liability for damage to the property of the Lessee or any subtenant of the
Lessee for any reason whatsoever except due to the Lessor's gross negligence or
willful misconduct.

                  (b) Nothing in this Lease shall be construed to release the
Lessor from the performance of any agreement on its part herein contained or as
a waiver by the Lessee of any rights or claims the Lessee may have against the
Lessor under this Lease or otherwise, but any recovery upon such rights and
claims shall be had from the Lessor separately (and not the Indenture Trustee),
it being the intent of this Lease that the Lessee shall be unconditionally and
absolutely obligated to perform filly all of its Obligations, agreements and
covenants under this Lease (including the obligation to pay Basic Rent and
Supplemental Rent) for the benefit of the Indenture Trustee, as pledgee of the
Bonds, the Noteholders and the Investor. The Lessee may, however, subject to any
provision of the Operative Agreements, at its own cost and expense and in its
own name or in the name of the Lessor, prosecute or defend any action or
proceeding or take any other action involving third persons which the Lessee
deems reasonably necessary in order to secure or protect its right of
possession, occupancy and use hereunder, and in such event the Lessor hereby
agrees to cooperate fully with the Lessee and to take all action necessary to
effect the substitution of the Lessee for the Lessor in any such action or
proceeding if the Lessee shall so request.

                  SECTION 4.4 PREPAYMENT. The Lessee may not at any time prepay

lawfully made, levied or assessed in lieu of or in addition to taxes or
assessments now customarily levied against real or personal property, and
further including all utility charges, assessments and other general
governmental charges and impositions whatsoever, foreseen or unforeseen, which
if not paid when due would impair the security of the Notes or encumber the
Lessor's title to the Facility; provided that with respect to any special
assessments or other governmental charges that are lawfully levied and assessed
which may be paid in installments, the Lessee shall be obligated to pay only
such installments thereof as become due and payable during the Term.

                  The Lessee shall have the right, subject to the provisions of
the Operative Agreements, in its own name or in the Lessor's name, to contest
the validity or amount of any tax, assessment or other governmental charge which
the Lessee is required to bear, pay and discharge pursuant to the terms of this
Article by appropriate legal proceedings instituted at least ten (10) days
before the tax, assessment or other governmental charge complained of becomes
delinquent if and provided (1) the Lessee, before instituting any such contest,
gives the Lessor written notice of its intention so to do, (2) the Lessee
diligently prosecutes any such contest and at all times effectively stays or
prevents any official or judicial sale therefor, under execution or otherwise,
(3) any Lien resulting from such tax, assessment or other governmental charge is
bonded or provided for, and (4) the Lessee promptly pays any final judgment
enforcing the tax, assessment or other governmental charge so contested and
thereafter promptly procures and records a recordable release or satisfaction
thereof. The Lessor agrees to cooperate fully with the Lessee in connection with
any and all administrative or judicial proceedings related to any tax,
assessment or other governmental charge. The Lessee shall indemnify and hold the
Lessor whole and harmless from any costs and expenses related to any of the
above.

                  SECTION 5.3 UTILITIES. All utilities and utility services used
in, on or about the Facility shall be paid for by the Lessee and shall be
contracted for by the Lessee in the Lessee's own name, and the Lessee shall, at
its sole cost and expense, procure any and all permits, licenses or
authorizations necessary in connection therewith. The Lessee shall be entitled
to receive any credit or refund with respect to any utility charge paid by the
Lessee and the amount of any credit or refund received by the Lessor on account
of any utility charges paid by the Lessee, net of the costs and expenses
incurred by the Lessor in obtaining such credit or refund, shall be promptly
paid over to the Lessee. All charges for utilities imposed with respect to the
Facility for a billing period during which this Lease expires or terminates

                  Prior to or simultaneously with the expiration of said

the insurance policies required under this Section, or originals or certificates
thereof, each bearing notations evidencing payment of the premiums or other

Indenture Trustee. All such policies of insurance pursuant to this Section, and
all renewals thereof, shall name the Board, the Bond Sublessor, the Lessor, the
Lessee, the Bond Trustee, and the Indenture Trustee as loss payees, as their
respective interests may appear, and shall contain a provision that such
insurance may not be canceled by the issuer thereof without at least thirty (30)
days' prior written notice (subject to the limitations inherent in the insurance
industry standard practice) to the Board, the Bond Sublessor, the Lessor, the
Bond Trustee, and the Indenture Trustee.

                  (b) Subject to the provisions of the Operative Agreements, in
the event of loss or damage to the Facility, the Net Proceeds of casualty

less than $50,000,000 and a deductible of not more than $500,000 in the
aggregate), and not less than $1,000,000 for property damage in any one
occurrence (subject to reasonable loss deductible clauses not to exceed $500,000
in the aggregate). The policies of said insurance shall contain a provision that
such insurance may not be canceled by the issuer thereof without at least thirty
(30) days' advance written notice to the Board, the Bond Sublessor, the Lessor,
the Bond Trustee, and the Indenture Trustee. Such policies or copies or
certificates thereof shall be furnished to the Lessor and the Indenture Trustee.

                  (b) In the event of a Casualty, the Net Proceeds of liability
insurance carried pursuant to this Section shall be applied toward the
satisfaction of the liability with respect to which such proceeds have been
paid.

                  SECTION 6.3 BLANKET INSURANCE POLICIES. The Lessee may satisfy
any of the insurance requirements set forth in this Article by using blanket

                           ALTERATION OF THE FACILITY

                  SECTION 7.1 ADDITIONS, MODIFICATIONS AND IMPROVEMENTS OF THE
FACILITY. So long as no Lease Event of Default has occurred and is continuing
and subject to the other provisions of this Article VII, the Lessee, at its sole
cost and expense, may at any time and from time to time make alterations,
renovations, improvements and additions to the Facility or any part thereof
(collectively, "MODIFICATIONS"); provided that: (i) except for any Modification
required to be made pursuant to a Legal Requirement or an Insurance Requirement,
no Modification shall impair the value, utility or remaining useful life of the
Facility from that which existed immediately prior to such Modification; (ii)
the Modification shall be performed expeditiously and in a good and work unalike
manner; (iii) the Lessee shall comply in all material respects with all Legal
Requirements (including all Environmental Laws) and Insurance Requirements
applicable to the Modification, including the obtaining of all permits and
certificates of occupancy, and the structural integrity of the Facility shall
not be adversely affected; (iv) the Lessee shall maintain or cause to be
maintained builders' risk-all risk insurance at all times when a Modification is
in progress; (v) subject to the terms of SECTION 3.3(b) relating to permitted
contests, the Lessee shall pay all costs and expenses and discharge any Liens
arising with respect to the Modification; (vi) such Modifications shall comply
with SECTIONS 3.5 and 5.1 and shall not change the primary character of the
Facility; and (vii) no improvements shall be demolished, except to the extent
such demolition, together with such replacement thereof or other Modification,
does not materially impair the value, utility or useful life of the Facility.
All Modifications (other than those that may be readily removed without
impairing the value, utility or remaining useful life of the Facility) shall
remain part of the realty and shall be subject to this Lease, and title thereto
shall immediately vest in the Lessor; provided, however, that additions to
machinery and equipment installed in the Facility by the Lessee not purchased or
acquired from funds deposited in the Escrow Account and not constituting
repairs, renewals or replacements of Equipment under SECTION 7.2 hereof shall
remain the property of the Lessee and may be removed

                                     - 14 -
<PAGE>
by the Lessee prior to the Expiration Date, subject to any provisions in the
Operative Agreements.

                  SECTION 7.2 REMOVAL OF EQUIPMENT. The Lessee shall have the
right, subject to any provisions in the Operative Agreements, provided no Lease
Event of Default has occurred and is continuing, to remove from the Facility and
(on behalf of the Lessor) sell, exchange or otherwise dispose of, without
responsibility or accountability to the Board, the Bond Sublessor, the Lessor,
the Bond Trustee, or the Indenture Trustee with respect thereto, any items of
machinery and equipment which constitute a part of the Equipment and which have
become inadequate, obsolete, worn out, unsuitable, undesirable or unnecessary or
which, in the sound discretion of the Lessee, are otherwise no longer useful to
the Lessee in its operations conducted on or in the Facility; provided that the
Lessee shall promptly replace all such Equipment so removed, except for any such
Equipment so removed having a fair market value of not more than $100,000 in any
one case and not more than $500,000 in the aggregate in any calendar year, with
machinery and equipment of the same or a different kind but with a value equal
to or greater than the fair market value of the Equipment (original cost of such
machinery or equipment less depreciation at rates calculated in accordance with
generally accepted accounting principles) so removed, and such machinery and
equipment shall be deemed a part of the Equipment, and (b) within thirty (30)
days after any such replacement, deliver to the Lessor and the Indenture Trustee
a certificate signed by the Lessee (1) setting forth a complete description,
including make, model and serial numbers, if any, of the machinery and equipment
which the Lessee has acquired to replace the Equipment so removed by the Lessee,
(2) stating the cost thereof, and (3) stating that the machinery and equipment
described in said certificate are fully paid for and have been installed on the
Facility.

                  The Lessor shall amend, and provide to the Indenture Trustee a
copy of, the list of Equipment maintained by it pursuant to SECTION 9.8 hereof
upon receipt of such certificate. All machinery and equipment which replaces
Equipment removed from the Facility by the Lessee pursuant to this Section shall
become and be deemed a part of the Facility.

                  In all cases, the Lessee shall pay all the costs and expenses
of any such removal and shall immediately repair at its expense all damage to
the Facility caused thereby. The Lessee's rights under this Section to remove
from the Facility machinery and equipment constituting a part of the Equipment
is intended only to permit the Lessee to maintain an efficient operation by the
removal of machinery and equipment which is no longer suitable to the Lessee's
use of the Facility for any of the reasons set forth in this Section, and such
right is not to be construed to permit a removal under any other circumstances
and specifically is not to be construed to permit the Lessee to make a wholesale
removal of the Equipment.

                  SECTION 7.3 ADDITIONAL IMPROVEMENTS. So long as no Lease Event
of Default has occurred and is continuing and subject to the other provisions of
this ARTICLE VII, the Lessee shall have and is hereby given the right, at its
sole cost and expense, subject to any provisions in the Operative Agreements, to
construct on portions of the Land not theretofore occupied by buildings or
improvements such additional buildings and improvements as the Lessee from time
to time may deem necessary or desirable for its business purposes. All
additional buildings and improvements constructed on the Land by the Lessee
pursuant to the authority of this Section shall become a part of the Facility.
The Lessee covenants and agrees to make any repairs and restorations required to
be made to the Facility because of the construction of, addition to, alteration
or removal of such additional buildings or improvements.

                  SECTION 7.4 PERMITS AND AUTHORIZATIONS. The Lessee shall not
do or permit others under its control to do any work on the Facility related to
any repair, rebuilding, restoration, replacement, modification or addition to
the Facility, or any part thereof, unless all requisite municipal and other
governmental permits and authorizations shall have been first procured. All such
work shall be done in a good and workmanlike mariner and in compliance with all
applicable building, zoning and other laws, ordinances, governmental regulations
and requirements and in accordance with the requirements, rules and regulations
of all insurers under the policies required to be carried under the provisions
of ARTICLE VI hereof.

                  SECTION 7.5 MECHANICS' LIENS.

                  (a) Neither the Lessor nor the Lessee shall do or suffer
anything to be done whereby the Facility, or any part thereof, may be encumbered
by any mechanics' or other similar Lien. Whenever and as often as any mechanics'
or other similar Lien is filed against the Facility, or any part thereof,
purporting to be for or on account of any labor done or materials or services
furnished in connection with any work in or about the Facility, the Lessee shall
comply with the provisions of the Operative Agreements and shall discharge the
same of record within sixty (60) days after the Lessee receives notice of the
filing thereof. Notice is hereby given that the Lessor shall not be liable for
any labor or materials furnished the Lessee or anyone claiming by, through or
under the Lessee, and that no mechanics' or other similar Lien for any such
labor, services or materials shall attach to or affect the reversionary or other
estate of the Board, the Bond Sublessor, or the Lessor in and to the Facility or
any part thereof.

                  (b) Notwithstanding paragraph (a) above, the Lessee shall have
the right, subject to the provisions of the Operative Agreements to contest any
such mechanics' or other similar Lien if within said 60-day period stated above
it notifies the Board, the Bond Sublessor, the Lessor, the Bond Trustee, and the
Indenture Trustee in writing of its intention so to do, and provided the Lessee
diligently prosecutes such contest, at all times effectively stays or prevents
any official or judicial sale of the Facility, or any part thereof or interest
therein, under execution or otherwise, and pays or otherwise satisfies any final
judgment enforcing such contested Lien claim and thereafter promptly procures
record release or satisfaction thereof. The Lessee shall indemnify and hold the
Board, the Bond Sublessor, the Lessor, the Bond Trustee, and the Indenture
Trustee whole and harmless from any loss, costs or expenses they may incur
related to any such contest. The Lessor shall cooperate fully with the Lessee in

                  (b) Should the Lessor elect to accept the Payment Offer, which
acceptance shall be at the Lessor's sole option and shall, subject to paragraph
(c) below, if made, be made in writing within sixty (60) days after receipt by
the Lessor of such offer, the Lessor and the Lessee shall enter into good faith
negotiations regarding the execution and delivery of a written amendment to this
Lease providing for the following:

                  (i) payment by the Lessor to the Lessee of the Expansion Cost
         within one hundred twenty (120) days after the date of the Lessor's
         acceptance of such Payment Offer, or in installment payments as agreed,
         or on the date of completion of the Expansion, whichever shall be the
         later;

                  (ii) an increase in the annual Basic Rent at such imputed rate
         of interest and upon such other terms as shall be agreed upon between
         the Lessor and the Lessee, but which shall be no less favorable than
         the prevailing interest rate and terms for first unsecured loans in a
         principal amount equal to the Expansion Cost for borrowers with credit
         ratings equivalent to that of the Lessee's at that time;

                  (iii) an increase in the Basic Rent to provide a rate of
         return on the Investor Contribution not less than the then prevailing
         market rate and an increase in the Termination Value and the Residual
         Guaranteed Maximum Amount; and

                  (iv) such other changes and amendments to the Bond Lease, the
         Bond Sublease, this Lease, the Guarantee, the Residual Value Policy and
         the other Operative Agreements as may be necessary or appropriate in
         view of such payment of the Expansion Cost by the Lessor.

The Lessee shall pay all costs and expenses incurred by the Lessor, the Board,
the Bond Sublessor, the Bond Trustee, the Indenture Trustee and the Noteholders
in connection with any such modification to this Lease and the other Operative
Agreements and such financing, including closing costs, brokerage fees, taxes,
recording charges and attorneys' fees and expenses.

                  (c) To the extent that the terms of the Security Documents or
any other Lien encumbering the Facility shall require the consent of the holder
or holders of any Lien on any of the Facility (the Secured Parties") to the
addition or construction of any Expansion or to the financing thereof by the
Lessor, the rights and obligations of the Lessor and the Lessee hereunder are
expressly conditioned upon the Lessee's obtaining, prior to the commencement of
any construction the Secured Parties written consent to such construction and to
such financing which consent may be withheld at the Secured Parties' sole
discretion.

                  (d) If the Lessor accepts the Payment Offer it may finance the
Expansion only by (i) issuance (in accordance with SECTION 2.1(d) of the
Indenture) and sale (subject to the right of first offer set forth in ARTICLE 11
of the Series A Note Purchase Agreement or any comparable provision in the
Series B Note Purchase Agreement) of Expansion Notes in the aggregate principal
amount not to exceed 97% of the Expansion Cost and (ii) receipt of additional
Investor Contribution in the amount not less than 3% of the Expansion Cost.

                  (e) Should any Payment Offer not be accepted by the Lessor
within said sixty (60) day period or should the Lessor and the Lessee be unable
in good faith to agree upon the terms of the modification of this Lease and the
other Operative Agreements, the Lessee shall,

                                     - 17 -
<PAGE>

subject to the provisions of this Lease, have the right to construct the
Expansion at the Lessee's sole cost and expense; provided that the Lessor shall
not reject the Payment Offer solely by reason of the Investor's inability or
unwillingness to provide the additional Investor Contribution referred to in the
foregoing clause (d) but shall (provided that all other conditions of this
Section have been satisfied) in such case allow the Lessee to secure the
additional Investor Contribution from other investors (complying with the
requirements of SECTION 10.1 of the Participation Agreement) that will upon
making of such additional Investor Contribution, become beneficiaries of the
Lessor, on parity with the Investor under the Operative Agreements. In any
event, the Expansion shall be the property of the Lessor and part of the
Facility subject to this Lease and the Lien of the Security Documents.

                  (f) Notwithstanding anything else in this SECTION 7.6 the
Lessor may prohibit in its sole discretion, any Expansion that could reasonably
be expected to cause a Material Adverse Effect.

                  SECTION 7.7 IMPROVEMENTS. If the Lessor determines that
additional financing is needed to complete the Facility by the Outside
Completion Date, the Lessor may, upon request of the Lessee, issue Lessor's
Series B Notes pursuant to the Indenture and in compliance with the other
Operative Agreements, in an aggregate principal amount not to exceed $5,000.000.

Environmental Violation and the actions taken by the Lessee (or its agents) in
response to such Environmental Violation, and a statement by the consultant that

                  SECTION 9.3 RIGHT OF ACCESS TO THE FACILITY. The Lessee agrees
that the Lessor, the Board, the Bond -Sublessor, the Bond Trustee, and the

rights or privileges, all with or without consideration and upon such terms and

                                   ARTICLE X

                         OPTION TO PURCHASE THE FACILITY

                  SECTION 10.1 PURCHASE OPTION. The Lessee shall have the option
on any Payment Date (exercisable by giving the Lessor irrevocable written notice
(the "PURCHASE NOTICE") of the Lessee's election to exercise such option not
less than one hundred and eighty (180) days prior to such Payment Date) to
purchase (i) the Lessor's interest in the Facility at any time, or (ii) the
Facility at any time after the seventh anniversary of the Closing Date; provided

                                     - 25 -
<PAGE>
that the conditions to the exercise of the Bond Sublessor's Purchase Option set
forth in SECTION 11.1 of the Bond Lease have been satisfied, in each case at a
price equal to the Termination Value. If the Lessee has exercised its option
pursuant to this Section (the "PURCHASE OPTION"), the Lessor shall transfer,
and, in the case of clause (ii) above, cause the Board and the Bond Sublessor to
transfer to the Lessee or the Lessee's designee all of the Lessor's, and their,
right, title and interest in and to the Facility in accordance with SECTION 3.6
as of the date specified in the Purchase Notice upon receipt of all Rent
(including the Termination Value) and other amounts then due and payable under
this Lease and other Operative Agreements. Upon receipt of such Purchase Notice,
the Lessor will give, and cause the Bond Sublessor to give, similar notices
exercising the comparable purchase options under the Bond Lease and the Bond
Sublease.

                  SECTION 10.2 MATURITY DATE PURCHASE OPTION. Not less than
twelve (12) months prior to the Maturity Date, the Lessee may give the Lessor
and Indenture Trustee irrevocable written notice (the "MATURITY DATE ELECTION
NOTICE") of the exercise of the Maturity Date Purchase Option or its election to
remarket the Facility pursuant to SECTION 10.3. The Lessee does not give a
Maturity Date Election Notice on or before the date twelve months prior to the
Maturity Date, then the Lessee shall be obligated to purchase the Facility
pursuant to this SECTION 10.2 (unless the Lessee has exercised the Purchase
Option in accordance with Section 10.1). If the Lessee has exercised the
Maturity Date Purchase Option, then on the Maturity Date the Lessee shall pay to
the Lessor the Termination Value and, upon receipt of such amount plus all other
amounts then due and payable under this Lease and any other Operative Agreement,
the Lessor shall transfer, and cause the Board and the Bond Sublessor to
transfer, to the Lessee or the Lessee's designee all of their right, title and
interest in and to the Facility in accordance with SECTION 3.6. Upon receipt of
such Maturity Date Election Notice, the Lessor will give, and cause the Bond
Sublessor to give, similar notices exercising the comparable purchase options
under the Bond Lease and the Bond Sublease. Notwithstanding anything herein to
the contrary, the Lessee shall be deemed to have elected the Maturity Date
Purchase Option if a Lease Event of Default has occurred and is continuing
during the Marketing Period, unless the Indenture Trustee and the Lessor have
consented to the Lessee's remarketing of the Facility under such circumstances,
which consent may be withheld by either of them in their sole and absolute
discretion.

                  SECTION 10.3 SALE PROCEDURE.

                  (a) During the Marketing Period, the Lessee, as nonexclusive
broker for the Lessor, shall use best efforts to obtain bids for the cash
purchase of the Facility for the highest price available in a commercially
reasonable sale in the relevant market, shall notify the Lessor promptly of the
name and address of each prospective purchaser and the cash price which each
prospective purchaser shall have offered to pay for the Facility and shall
provide the Lessor with such additional information about the bids and the bid
solicitation procedure as the Lessor may request from time to time. The Lessor
may reject any and all bids and may also obtain bids for the purchase of the
Facility; provided, however, that notwithstanding the foregoing, the Lessor
shall accept the highest bid providing for the sale of the Facility if such bid
is greater than or equal to the sum of the Non-Guaranteed Residual Amount and
all costs and expenses referred to in SECTION 10.4(i) and is a bona fide offer
by a third party purchaser who is not an Affiliate of the Lessee. If, ten
Business Days prior to the Maturity Date, no prospective purchaser shall have
offered to pay for the Facility in an amount equal to or greater than the sum of
the Non-Guaranteed Residual Amount and all costs and expenses referred to in
SECTION 10.4(i), the Lessor may elect to retain the Facility by giving the
Lessee at least two (2) Business Days' prior written notice of the Lessor's
election to retain the Facility, and upon receipt of such notice, the

                                     - 26 -
<PAGE>
Lessee shall surrender the Facility to the Lessor on the Maturity Date and pay
the Lessor the amounts provided for in SECTION 10.3(b). Unless the Lessor shall
have elected to retain the Facility pursuant to the preceding sentence, the
Lessor, or the Lessee on its behalf, shall sell the Facility free of any Lessor
Liens, without recourse or warranty, for cash to the purchaser or purchasers
identified by the Lessee or the Lessor, as the case may be, and the Lessee shall
surrender the Facility so sold to the purchaser in the condition specified in
SECTION 3.7. Failure to sell the Facility shall not constitute a Lease Event of
Default so long as the Lessee has complied with its obligations set forth in
this SECTION 10.3.

                  (b) If the Facility has not been sold on or prior to the
Maturity Date for any reason whatsoever, then on the Maturity Date, (i) the
Lessee shall pay to the Lessor the Maximum Residual Guarantee Amount and all
Supplemental Rent and other amounts then owing hereunder or under the other
Operative Agreements and (ii) this Lease and all of the Lessee's right, title
and interest in the Facility shall terminate, and the Lessee shall surrender the
Facility in the condition specified in SECTION 3.7. Thereafter, the Lessee will
use commercially reasonable efforts to assist the Lessor in remarketing the
Facility and transfer its interest therein to the Lessor.

                  SECTION 10.4 APPLICATION OF PROCEEDS FROM SALE. The Lessor
shall apply the proceeds of sale of the Facility in the following order of
priority:

                  (i) FIRST, to pay or to reimburse the Lessor and the Lessee
for the payment of all reasonable costs and expenses incurred by the Lessor in
connection with the sale; and

                  (ii) SECOND, the balance shall be paid to the Indenture
Trustee to be applied pursuant to the provisions of the Indenture.

                  SECTION 10.5 INDEMNITY FOR EXCESSIVE WEAR. If the proceeds of
the sale described in SECTION 10.3(a), less all expenses incurred by the Lessor
and the Lessee in connection with such sale, shall be less than the
Non-Guaranteed Residual Amount (such difference, the "Net Sale Proceeds
Shortfall") and if it shall have been determined (pursuant to the Appraisal
Procedure) that the Fair Market Sales Value of the Facility shall have been
impaired by greater than expected wear and tear during the Term, the Lessee
shall pay to the Lessor within ten (10) days after receipt of the Lessor's
written statement (i) the amount of such excess wear and tear determined by the
Appraisal Procedure set forth in SECTION 10.6 or (ii) the amount of the Net Sale
Proceeds Shortfall, whichever amount is less.

                  SECTION 10.6 APPRAISAL PROCEDURE. For determining the Fair
Market Sales Value of the Facility or any other amount which may, pursuant to
any provision of any Operative Agreement, be determined by an appraisal
procedure, the Lessor and the Lessee shall use the following procedure (the
"Appraisal Procedure"). The Lessor and the Lessee shall endeavor to reach an
agreement as to such amount for a period often (10) days from commencement of
the Appraisal Procedure, and if they cannot agree within ten (10) days, then two
qualified appraisers, one chosen by the Lessee and one chosen by the Lessor,
shall agree thereupon, but if either party shall fail to choose an appraiser
within twenty (20) days after notice from the other party of the selection of
its appraiser, then the appraisal by such appointed appraiser shall be binding
on the Lessee and the Lessor. If the two appraisers cannot agree within twenty
(20) days after both shall have been appointed, then a third appraiser shall be
selected by the two appraisers or, failing agreement as to such third appraiser
within thirty (30) days after both shall have been appointed, by the American
Arbitration Association. The decisions of the three appraisers shall be given
within twenty (20) days of the appointment of the third appraiser and the
decision of the

                                     - 27 -
<PAGE>
appraiser most different from the average of the other two shall be discarded
and such average shall be binding on the Lessor and the Lessee; provided that if
the highest appraisal and the lowest appraisal are equidistant from the third
appraisal, the third appraisal shall be binding on the Lessor and the Lessee.
The reasonable fees and expenses of all of the appraisers shall be paid by the
Lessee.

                  SECTION 10.7 CERTAIN OBLIGATIONS CONTINUE. During the
Marketing Period, the obligation of the Lessee to pay Rent with respect to the
Facility (including the installment of Basic Rent and all Supplemental Rent due
on the Maturity Date) shall continue undiminished until payment in full, without
duplication, to the Lessor of the sale proceeds, the Maximum Residual Guarantee
Amount, if any, the amount due under SECTION 10.5, (ii) any, and all other
amounts due to the Lessor with respect to the Facility. The Lessor shall have
the right, but shall be under no duty, to solicit bids, to inquire into the
efforts of the Lessee to obtain bids or otherwise to take action in connection
with any such sale, other than as expressly provided in this Article.

                                   ARTICLE XI

                              DEFAULTS AND REMEDIES

                  SECTION 11.1 EVENTS OF DEFAULT. If any one or more of the
following events shall occur (each a "Lease Event of Default"):

                  (a) Default in the due and punctual payment of (i) Basic Rent
         or Supplemental Rent (except to the extent such Supplemental Rent
         represents the payment of the Maximum Residual Guarantee Amount or the
         Termination Value) when the same has become due and payable and such
         default shall have continued for three days or (ii) the Maximum
         Residual Guarantee Amount or the Termination Value when the same has
         become due and payable; or

                  (b) Default in the due observance or performance of (x)
         Article VI or (y) any covenant, agreement, obligation or provision of
         this Lease or any other Operative Agreements on the Lessee's part to be
         observed or performed (except as specified elsewhere in this SECTION
         11.1), and such default shall continue for thirty (30) days after the
         Lessee has been given a notice specifying such default; provided that
         such 30-day period shall be extended (up to a maximum period of 180
         days) as to defaults which cannot be cured with the payment of money
         but are curable, though not reasonably capable of cure within such
         30-day period, so long as the Lessee has commenced to cure such default
         prior to the end of such 30-day period and prosecutes such cure to
         completion and such extension, individually or in the aggregate, could
         not reasonably be expected to have a Material Adverse Effect; or

                  (c) Any Agency Agreement Event of Default, any default under
         the Guarantee, any event of default under the Escrow Agreement or any
         Indenture Event of Default; or

                  (d) The Lessee shall: (1) admit in writing its inability to
         pay its debts as they become due; or (2) file a petition in bankruptcy
         or for reorganization, arrangement, composition, readjustment,
         liquidation, dissolution or similar relief under the federal bankruptcy
         laws of the United States of America or any other similar present or
         future

         federal or state statute or regulation, or file a pleading asking for
         such relief; or (3) make an assignment for the benefit of creditors; or
         (4) consent to the appointment of a trustee, receiver or liquidator for
         all or a major portion of its property or fail to have the appointment
         of any trustee, receiver or liquidator vacated or set aside; or (5) be
         finally adjudicated as bankrupt or insolvent under any federal or state
         law; or (6) be subject to any proceeding, or suffer the entry of a
         final and non-appealable court order, under any federal or state law
         appointing a trustee, receiver or liquidator for all or a major part of
         its property or ordering the winding-up or liquidation of its affairs,
         or approving a petition filed against it under the federal bankruptcy
         laws of the United States of America, which order or proceeding shall
         not be dismissed, vacated, denied, set aside or stayed within sixty
         (60) days after the day of entry or commencement; or

                  (e) The Lessee shall vacate or abandon the Facility, or shall
         have been ejected from the Facility or any material portion thereof by
         reason of a defect in title to the Facility or violation of any Legal
         Requirement; or

                  (f) Default under any Indebtedness of the Lessee (after the
         expiration of any applicable grace period) in making any payment in
         respect thereof or any default or other event shall occur or condition
         shall exist in respect of any Indebtedness, the effect of which is to
         cause, or permit any holder of such Indebtedness to cause, such
         Indebtedness to become due before its stated maturity or before its
         regularly scheduled dates of payment; or

                  (g) A judgment, decree, writ, warrant of attachment or similar
         process in an amount equal to or exceeding, individually or in the
         aggregate, $500,000 shall be entered against the Lessee or the Facility
         that is not satisfied, vacated, discharged, appealed from (with
         execution or similar process continuously stayed) within thirty (30)
         days of such entry; or

                  (h) Any representation or warranty of the Lessee set forth in
         any Operative Agreement or in any certificate delivered pursuant
         thereto shall be incorrect in any material respect when made;

then, in any such event, the Lessor may, in addition to the other rights and
remedies provided for in this Lease, terminate this Lease by giving the Lessee
five (5) days notice of such termination, whereupon this Lease shall terminate.
The Lessee shall pay as Supplemental Rent all costs and expenses incurred by or
on behalf of the Lessor and the Indenture Trustee, including fees and expenses
of counsel, as a result of any Lease Event of Default hereunder.

                  SECTION 11.2 FINAL LIQUIDATED DAMAGES. If a Lease Event of
Default shall have occurred and be continuing, the Lessor shall have the right
to recover, by demand upon the Lessee, and the Lessee shall pay to the Lessor,
without duplication, as final liquidated damages (but without limiting its
obligations hereunder or under the other Operative Agreements to indemnify the
Lessor, the Indenture Trustee and each other Indemnified Person), and in lieu of
all damages beyond the date of such demand, the sum of (a) the Termination
Value, plus (b) all Supplemental Rent and other amounts accruing under this
Lease. Upon payment of such sum, the Lessee shall be entitled to receive, at the
Lessee's request and cost, the conveyance and assignment of the Board's, the
Bond Sublessor's, and the Lessor's right, title and interest in the Facility, in
each case in recordable form and otherwise in conformity with local custom and
free and clear of the Lien of the Security Documents and any Lessor Liens. The
Facility shall be

                                     - 29 -
<PAGE>
conveyed to the Lessee (or the Lessee's designee) "AS IS" in all respects. If
any statute or rule of law shall limit the amount of such final liquidated
damages to less than the amount agreed upon, the Lessor shall be entitled to the
maximum amount allowable under such statute or rule of law, but the Lessee shall
not be entitled to receive the conveyance and assignment of the Facility unless
the Lessee shall have paid in full the sum specified in the first sentence of
this Section.

                  SECTION 11.3 LEASE REMEDIES. If the Lessor is unable to
enforce the remedies set forth in Section 11.2 against the Lessee and the
Facility, the following remedies shall be available to the Lessor with respect
to the Lessee and the Facility:

                  (a) Surrender of Possession. If a Lease Event of Default
shall have occurred and be continuing, and whether or not this Lease shall have
been terminated pursuant to SECTION 11.1, the Lessee shall, upon thirty (30)
days written notice, surrender to the Lessor possession of the Facility and the
Lessee shall quit the same. The Lessor may enter upon and repossess the Facility
by the means as are available at law or in equity, and may remove the Lessee and
all other Persons and remove or retain any and all personal property and the
Lessee's equipment and personality and severable Modifications from the
Facility. The Lessor shall have no liability by reason of any such entry,
repossession, removal or retention performed in accordance with applicable law.

                  (b) Reletting. If a Lease Event of Default shall have occurred
and be continuing, and whether or not this Lease shall have been terminated
pursuant to SECTION 11.1, the Lessor may, but shall be under no obligation to,
relet all, or any portion, of the Facility; for the account of the Lessee or
otherwise, for such term or terms (which may be greater or less than the period
which would otherwise have constituted the balance of the Term) and on such
conditions (which may include concessions or free rent) and for such purposes as
the Lessor may determine, and the Lessor may collect, receive and retain the
rents resulting from such reletting. The Lessor shall not be liable to the
Lessee for any failure to relet the Facility or for any failure to collect any
rent due upon such reletting.

                  (c) Damages. None of (a) the termination of this Lease
pursuant to SECTION 11.1; (b) the repossession of the Facility; or (c) except to
the extent required by applicable law, the failure of the Lessor to relet all,
or any portion, of the Facility, the reletting of all or any portion thereof, or
the failure of the Lessor to collect or receive any rentals due upon any such
reletting shall relieve the Lessee of its liability and obligations hereunder,
all of which shall survive any such termination, repossession or reletting. If
any Lease Event of Default shall have occurred and be continuing and
notwithstanding any termination of this Lease pursuant to SECTION 11.1, the
Lessee shall forthwith pay to the Lessor all Basic Rent, Supplemental Rent
(including the Termination Value) and other sums due and payable hereunder to
and including the date of such termination. Thereafter, on the days on which the
Basic Rent or Supplemental Rent, as applicable, are payable under this Lease or
would have been payable under this Lease if the same had not been terminated
pursuant to SECTION 11.1 and until the end of the Term or what would have been
the Term in the absence of such termination the Lessee shall pay the Lessor as
current liquidated damages (it being agreed that it would be impossible
accurately to determine actual damages) an amount equal to the Basic Rent and
Supplemental Rent that are payable under this Lease or would have been payable
by the Lessee hereunder if this Lease had not been terminated pursuant to
SECTION 11.1, less the net proceeds, if any, which are actually received by the
Lessor with respect to the period in question of any reletting of the Facility
or any portion thereof; provided that the Lessee's obligation to make payments
of Basic Rent and Supplemental Rent under this SECTION 11.3 shall continue only
so long as the Lessor shall not have received the

                                     - 30 -
<PAGE>
amounts specified in SECTION 11.2 or SECTION 11.3(d). In calculating the amount
of such net proceeds from reletting, there shall be deducted all of the
Lessor's, the Indenture Trustee's and any Noteholder's expenses in connection
therewith, including repossession costs, brokerage commissions, fees and
expenses for counsel and any necessary repair or alteration costs and expenses
incurred in preparation for such reletting. To the extent the Lessor receives
any damages pursuant to this SECTION 11.3, such amounts shall be regarded as
amounts paid on account of Rent.

                  (d) Acceleration of Rent. If a Lease Event of Default shall
have occurred and be continuing, and this Lease shall not have been terminated
pursuant to SECTION 11.1, and whether or not the Lessor shall have collected any
current liquidated damages pursuant to SECTION 11.3(c), the Lessor may upon
written notice to the Lessee (to the extent permitted by applicable law)
accelerate all payments of Basic Rent due hereunder and, upon such acceleration,
the Lessee shall immediately pay the Lessor, as final liquidated damages and in
lieu of all current liquidated damages on account of such Lease Event of Default
beyond the date of such acceleration (it being agreed that it would be
impossible accurately to determine actual damages) an amount equal to the sum
of(a) all Basic Rent (assuming interest at a rate per annum equal to the Overdue
Rate), as applicable, due from the date of such acceleration until the end of
the Term, (b) the Maximum Residual Guarantee Amount that would be payable under
SECTION 10.3(b) assuming the proceeds of the sale pursuant to such SECTION
10.3(a) are equal to zero, which sum is then discounted to present value at a
rate equal to the rate then being paid on United States treasury securities with
maturities corresponding to the then remaining Term plus 0.50%. Following
payment of such amount by the Lessee, so long as this Lease shall not have been
terminated pursuant to SECTION 11.1, the Lessee will be permitted to stay in
possession of the Facility for the remainder of the Term, subject to the terms
and conditions of this Lease, including the obligation to pay Supplemental Rent.
if any statute or rule of law shall limit the amount of such final liquidated
damages to less than the total amount of Rent for which this Lease expressly
provides, the Lessor shall be entitled to the maximum amount allowable under
such statute or rule of law, but the Lessee shall not be relieved of its
obligations hereunder unless the Lessee shall have paid in full the Termination
Value plus all Supplemental Rent and other amounts of Rent for which this Lease
expressly provides.

                  SECTION 11.4 WAIVER OF CERTAIN RIGHTS. If this Lease shall be
terminated pursuant to Section 11.1, the Lessee waives, to the fullest extent
permitted by law, (a) any notice of re-entry or the institution of legal
proceedings to obtain re-entry or possession; (b) any right of redemption,
re-entry or repossession; (c) the benefit of any laws now or hereafter in force
exempting property from liability for rent or for debt; and (d) any other rights
which might otherwise limit or modify any of the Lessor's nights or remedies
under this Article XI.

                  SECTION 11.5 ASSIGNMENT OF RIGHTS. Under Contracts if a Lease
Event of Default shall have occurred and be continuing and whether or not this
Lease shall have been terminated pursuant to SECTION 11.1 the Lessee shall upon
the Lessor's demand immediately assign, transfer and set over to the Lessor all
of the Lessee's right, title and interest in and to each agreement executed by
the Lessee in connection with the construction, renovation, development, use or
operation of the Facility (including all right, title and interest of the Lessee
with respect to all warranty, performance, service and indemnity provisions).

                  SECTION 11.6 SURVIVAL OF OBLIGATIONS. The Lessee covenants and
agrees with the Lessor, the Bond Trustee, the Indenture Trustee and Noteholders
that its obligations under this Lease shall survive the cancellation and
termination of this Lease, for any cause, and that the

                                     - 31 -
<PAGE>
Lessee shall continue to pay the Basic Rent and Supplemental Rent and perform
all other obligations provided for in this Lease, all at the time or times
provided in this Lease; provided, however, that upon the payment of all Basic
Rent and Supplemental Rent required under Article IV hereof, and upon the
satisfaction and discharge of the Bond Indenture and the Indenture, the Lessee's
obligation under this Lease shall thereupon cease and terminate in full.

                  SECTION 11.7 PERFORMANCE OF THE LESSEE'S OBLIGATIONS BY THE
LESSOR, THE BOND TRUSTEE OR THE INDENTURE TRUSTEE. If the Lessee shall fail to
keep or perform any of its obligations as provided in this Lease, then the
Lessor, the Bond Trustee or the Indenture Trustee may (but shall not be
obligated to), and without waiving or releasing the Lessee from any obligation
hereunder, as an additional but not exclusive remedy, perform such obligation,
and all amounts paid by the Lessor, the Bond Trustee or the Indenture Trustee
and all necessary incidental reasonable costs and expenses incurred by the
Lessor, the Bond Trustee or the Indenture Trustee in performing such obligations
shall be deemed Supplemental Rent and shall be paid to the Lessor, the Bond
Trustee or the Indenture Trustee on demand, and if not so paid by the Lessee,
the Lessor, the Bond Trustee or the Indenture Trustee shall have the same rights
and remedies provided for in this Article XI for a default in the payment of
Basic Rent.

                  SECTION 11.8 RIGHTS AND REMEDIES CUMULATIVE. The rights and
remedies provided herein and those available at law, equity or otherwise,
including any mortgage foreclosure remedies provided under the laws of the State
of Missouri, shall be construed as cumulative and continuing rights and
remedies, in addition to (and not in limitation of) one another. None of them
shall be exhausted by the exercise of any of them on one or more occasions. The
Lessor, the Bond Trustee and the Indenture Trustee shall each be entitled to
specific performance and injunctive or other equitable relief for any breach or
threatened breach of any of the provisions of this Lease, notwithstanding
availability of an adequate remedy at law, and the Lessee hereby waives the
right to raise such defense in any proceeding in equity.

                  SECTION 11.9 WAIVER OF BREACH. No waiver of any breach of any
covenant or agreement herein contained shall operate as a waiver of any
subsequent breach of the same covenant or agreement or as a waiver of any breach
of any other covenant or agreement, and in case of a breach by the Lessee of any
covenant, agreement or undertaking, the Lessor, the Bond Trustee or the
Indenture Trustee may nevertheless accept from the Lessee any payment or
payments hereunder without in any way waiving the Lessor's, the Bond Trustee's
or the Indenture Trustee's right to exercise any of its rights and remedies
provided for herein with respect to any such default or defaults of the Lessee
which were inexistence at the time such payment or payments were accepted by the
Lessor, the Bond Trustee or the Indenture Trustee. Notwithstanding anything else
contained herein, so long as any Bond or any Note is outstanding, any action by
the Bond Trustee or the Indenture Trustee automatically binds the Lessor with
respect to such action.

                  SECTION 11.10 INDENTURE TRUSTEE'S EXERCISE OF THE LESSOR'S
REMEDIES. Whenever any Lease Event of Default shall have occurred and be
continuing, the Indenture Trustee may, but shall not be obliged to, exercise any
or all of the rights of the Lessor under this Article. In addition, the
Indenture Trustee shall have available to it all of the remedies prescribed by
the Indenture.

            SECTION 12.1      ASSIGNMENT; SUBLEASE.

            (a) Subject to the provisions of the Operative Agreements and so
long as no Lease Event of Default has occurred and is continuing, the Lessee
shall have the right to assign, transfer, encumber or dispose of this Lease, but
only with the written consent of all of the Board, the Bond Sublessor, the

such consents shall be void. With respect to any assignment, the Lessee shall
comply with the following conditions:

      acknowledged by the assignor and in proper form for recording;

            (2)   Such assignment shall include the entire then unexpired
      term of this Lease;

            (3) A duplicate original of such assignment shall be delivered to
      the Board, the Bond Sublessor, the Lessor, the Investor, the Bond Trustee
      and the Indenture Trustee within ten (10) days after the execution
      thereof, together with an assumption agreement, duly executed and
      acknowledged by the assignee in proper form for recording, by which the
      assignee shall assume all of the terms, covenants and conditions of this
      Lease on the part of the Lessee to be thereafter performed and observed;

            (4) At the time of any such assignment there shall be no damage or
      destruction to the Facility which has not been repaired, restored and
      replaced in accordance with the provisions of this Lease, unless
      sufficient funds then held by the Lessee for the purposes of such repair,
      restoration and replacement are simultaneously transferred to the
      assignee; and

            (5) all Rent and all other amounts accruing under this Lease and the
      other Operative Agreements up to and including the effective date of the
      assignment shall have been paid in full.

            Upon the satisfaction of the conditions set forth herein, the
assignor shall be relieved of all further liability occurring on and after the
effective date of such assignment.

            (b) Subject to the provisions of the Operative Agreements, the
Lessee shall have the right to sublet all or any portion of the Facility. No
sublease of the Facility, or any portion thereof, shall release or discharge the
Lessee from its primary liability for the payment of the Basic Rent and
Supplemental Rent hereunder and the performance of all of the covenants and
agreements herein contained, and its duties and obligations under this Lease
shall continue as if no such sublease had been made. The Lessee shall, within
ten (10) days after the delivery thereof, furnish or cause to be furnished to
the Board, the Bond Sublessor, the Lessor, the Bond Trustee and the Indenture
Trustee a true and correct copy of each such sublease. Any sublease

                                      -33-

<PAGE>

may provide, at the Lessor's option, that the Lessor's consent shall not be
required in respect of any further subletting thereunder if such further
subletting is for a similar purpose as the original sublease and is for a
purpose permissible under this Lease.

            SECTION 12.2 ASSIGNMENT BY THE LESSOR. The Lessor shall assign and
pledge its interest in this Lease to the Bond Trustee pursuant to the Assignment
of Lease, as security for payment of the principal of, premium, if any, and
interest on, the Bonds and the Notes and the Lessee shall consent to such pledge
and assignment pursuant to the Consent to Assignment.

            SECTION 12.3 ASSIGNMENT OF LEASE. In order to secure the payment and
performance of the obligations of the Lessee under this Lease, the Lessee hereby
pledges and assigns to the Lessor all right, title and interest of the Lessee
in, to and under this Lease pursuant to the Lessee Leasehold Deed of Trust.

written consent of the Indenture Trustee and the Bond Trustee, given in
accordance with the provisions of the Indenture and the Bond Indenture (which
consent may be withheld in the Indenture Trustee's and the Bond Trustee's
absolute discretion), and any agreement or writing purporting to do so will be
void ab initio.

Party a certificate signed by an individual having the office of vice president
or higher in the Certifying Party certifying that this Lease is in full force

obligations hereunder (and, if so, the nature of such alleged default). Any such
certificate furnished pursuant to this SECTION 14.8 may be relied upon by the
Requesting Party (provided that such reliance shall not relieve such Requesting
Party from its obligations hereunder or under any other Operative Agreements),
and any existing or prospective mortgagee, purchaser or lender, and any
accountant or auditor, of, from or to the Requesting Party (or any Affiliate
thereof).

            SECTION 14.9 MEMORANDUM OF LEASE. This Lease shall not be recorded,

leasehold estate created by this Lease, or any interest in this Lease

                                      -36-

or in any such leasehold estate, and (ii) any such other estate or interest in
the Facility or any part thereof; and no such merger shall occur unless and
until all persons having an interest (including a security interest) in (a) this
Lease or the leasehold estate created by this Lease and (b) any such other
estate or interest in the Facility or any part thereof, shall join in a written
instrument effecting such merger and shall duly record the same.

                                    GUARANTEE

            GUARANTEE dated as of August 31, 1999 made by MASTERCARD
INTERNATIONAL INCORPORATED, a non-stock membership corporation organized under
the laws of the State of Delaware (the "Guarantor"), in favor of STATE STREET
BANK AND TRUST COMPANY OF MISSOURI, N.A., a national banking association, as
Indenture Trustee (in such capacity, the "Indenture Trustee") for the
Noteholders (the "Noteholders") under the Indenture, dated as of the date hereof
(as amended, supplemented, extended or otherwise modified from time to time, the
"Indenture"), from MCI O'Fallon 1999 Trust, a Delaware business trust (the
"Borrower"), to the Indenture Trustee.

                              Preliminary Statement

            Pursuant to the Note Purchase Agreement, dated as of the date hereof
(as amended, supplemented, extended or otherwise modified from time to time, the
"Series A Note Purchase Agreement"), the Noteholders have severally agreed to
purchase from the Borrower a $149,380,000 aggregate principal amount of its
7.36% Series A Senior Secured Notes due September 1, 2009 (the "Series A Notes,"
such term to include any such Notes issued in substitution or replacement
therefor under the Indenture), upon the terms and subject to the conditions set
forth therein, issued by the Borrower under the Indenture. The Borrower has
entered into the Series A Note Purchase Agreement for the purpose of
facilitating the financing, with the proceeds of the Series A Notes, for the
acquisition and construction of the Facility.

            The Borrower will sublease the Facility to the Lessee pursuant to
the Lease, which will be assigned to the Bond Trustee for the benefit of
Bondholders, as a security for the Bonds.

            The Borrower will use the proceeds of the Series A Notes, together
with other funds, to purchase the Series A Bonds. The Series A Bonds will be
endorsed to and registered in the name of the Indenture Trustee, and the rights,
privileges and benefits of the Bondholders under the Bond Indenture will be
assigned to the Indenture Trustee, in each case, for the benefit of the
Noteholders.

            In the event that additional financing is needed to complete the
Facility, the Borrower may, upon request of the Lessee and the Satisfaction of
certain conditions in the Indenture and the Participation Agreement, issue its
Series B Senior Secured Notes due September 1, 2009 (the "Series B Notes," such
term to include any such Notes issued in substitution or replacement therefore
under the Indenture, and together with the Series A Notes, the "Notes"), to be
sold pursuant to a note purchase agreement substantially in the form of the
Series A Note Purchase Agreement (as amended, supplemented, extended or
otherwise modified from time to time, the "Series B Note Purchase Agreement,"
and together with the Series A Note Purchase Agreement, the "Note Purchase
Agreements").

            The Borrower will use the proceeds of the Series B Notes, together
with other funds, to purchase the Series B Bonds. The Series B Bonds will be
endorsed to and registered in the name of the Indenture Trustee, and the rights,
privileges and benefits of the Bondholders

<PAGE>
under the Bond Indenture will be assigned to the Indenture Trustee, in each
case, for the benefit of the Noteholders.

            It is a condition precedent to the obligation of the Purchasers to
purchase Series A Notes from the Borrower under the Series A Note Purchase
Agreement (and, if any Series B Notes are issued and sold, it will be a
condition to the purchase thereof) that the Guarantor shall have executed and
delivered this Guarantee to the Indenture Trustee for the ratable benefit of the
Noteholders of Series A Notes and Series B Notes (if any), from time to time
Outstanding.

            NOW, THEREFORE, in consideration of the premises and to induce the
Indenture Trustee to enter into the Indenture and to induce the Purchasers to
purchase the Series A Notes from the Borrower under the Series A Note Purchase
Agreement (and, if any Series B Notes are issued and sold, to induce the
purchasers thereof to purchase any such Series B Notes under the Series B Note
Purchase Agreement), the Guarantor hereby agrees with the Indenture Trustee, for
the ratable benefit of the Noteholders, as follows:

            1. Defined Terms; Calculations and Computations. Capitalized terms
not otherwise defined herein shall have the meanings set forth on Annex A to the
Participation Agreement dated as of the date hereof among the Lessee, the
Lessor, the Trust Company, the Investor, the Indenture Trustee and the
Purchasers.

            2. Guarantee. (a) Subject, only in the case of the Non-Guaranteed
Residual Amount, to the limitations contained in Section 2(b), the Guarantor
hereby unconditionally and irrevocably guarantees and agrees to act as a primary
obligor and as a surety to the Indenture Trustee, for the ratable benefit of the
Noteholders and their respective successors, indorsees, transferees and assigns,
with respect to the prompt and complete payment and performance by the Borrower
and the Lessee, as applicable, when due (whether at the stated maturity, by
acceleration or otherwise) of each of the following (collectively, the
"Guaranteed Obligations"): (i) the unpaid principal of and interest on the Notes
and all other obligations and liabilities of the Borrower to the Indenture
Trustee or the Noteholders (including any applicable Make Whole Premium, any
interest accruing at the then applicable rate provided in respect of the Notes
after the occurrence of an Indenture Event of Default and any such interest
accruing at the then applicable rate provided in respect of the Notes after the
filing of any petition in bankruptcy, or the commencement of any insolvency,
reorganization or like proceeding, relating to the Borrower or the Lessee,
whether or not a claim for post-filing or post-petition interest is allowed in
such proceeding), whether direct or indirect, absolute or contingent, due or to
become due, now existing or hereafter incurred, which may arise under, out of,
or in connection with, the Note Purchase Agreements, the Notes, the Indenture,
the other Operative Agreements or any other document made, delivered or given in
connection therewith, whether on account of principal, interest, any applicable
Make Whole Premium, reimbursement obligations, fees, indemnities, costs,
expenses or otherwise (including all reasonable fees and expenses of counsel to
the Indenture Trustee or to the Noteholders that are required to be paid by the
Borrower pursuant to the terms of the Note Purchase Agreements or any other
Operative Agreement), (ii) all amounts payable by the Lessee under the Lease,
including, without limitation, the Basic Rent, the Supplemental Rent, the
Maximum Residual Guarantee Amount, the Construction Termination Amount and the
Termination Value, whether direct or indirect, absolute or contingent, due or to
become due, now existing or hereafter incurred, which may arise under, out of or
in connection with, the Lease, and (iii) all other amounts payable by the Lessee
under any of the Operative

                                      -2-
<PAGE>
Agreements (including indemnities) to the Indenture Trustee and/or the
Noteholders or to the Lessor for the direct or indirect benefit of the Indenture
Trustee and/or the Noteholders.

            (b) Anything herein or in any other Operative Agreement to the
contrary notwithstanding, the Guarantor shall not at any time be required to
make any payment hereunder in respect of the Non-Guaranteed Residual Amount: (A)
during the Construction Period, except with respect to the Guaranteed
Obligations following (i) any breach of the environmental indemnities set forth
in Section 11.1(a) of the Participation Agreement, (ii) third party Claims
(including by the Noteholders) against the Borrower caused by or resulting from
the Guarantor's own actions or failure to act (including any default in payment
under this Guarantee) other than Claims arising directly or indirectly out of
the Guarantor's (in its capacity as the Construction Agent) failure to achieve
the Completion of the Facility by the Outside Completion Date, (iii) Claims
brought by the Borrower relating to fraud, misappropriation of funds, illegal
acts, or willful misconduct on the part of the Guarantor (whether in its
capacity as the Lessee, the Guarantor or the Construction Agent) or (iv)
bankruptcy or insolvency of the Guarantor; or (B) at any time after the
Construction Period, unless at such time (i) a default under this Guarantee
(including any breach of the Guarantor's obligations to pay the entirety of all
amounts under the Notes and the Indenture due upon any acceleration thereof, but
excluding defaults relating to breaches of Article VIII and Sections 9.3 (other
than any breach of the Guarantor's payment obligations with respect to the Notes
and the Indenture, as aforesaid) through 9.7, inclusive, hereof) or (ii) a
Specified Lease Event of Default, in any case, has occurred and is continuing.

            (c) The Guarantor further agrees to pay any and all expenses
(including all reasonable fees and expenses of counsel) which may be paid or
incurred by the Indenture Trustee or any Noteholder, after the occurrence and
during the continuance of an Indenture Event of Default, in enforcing, or
obtaining advice of counsel in respect of, any rights with respect to, or
collecting, any or all of the Guaranteed Obligations and/or enforcing any rights
with respect to, or collecting against, the Guarantor under this Guarantee. This
Guarantee shall remain in full force and effect until the Guaranteed Obligations
and all amounts owing hereunder are indefeasibly paid in full, notwithstanding
that from time to time prior thereto the Borrower may be free from any
Guaranteed Obligations.

            (d) No payment or payments made by the Borrower, the Guarantor or
any other Person or received or collected by the Indenture Trustee or any
Noteholder from the Borrower, the Guarantor or any other Person by virtue of any
action or proceeding or any set-off or appropriation or application at any time
or from time to time in reduction of or in payment of the Guaranteed Obligations
shall be deemed to modify, reduce, release or otherwise affect the liability of
the Guarantor hereunder. The Guarantor shall, notwithstanding any such payment
or payments, remain liable for the Guaranteed Obligations until the Guaranteed
Obligations and all amounts owing hereunder are indefeasibly paid in full.

            (e) The Guarantor agrees that whenever, at any time, or from time to
time, it shall make any payment to the Indenture Trustee or any Noteholder on
account of its liability hereunder, it will notify the Indenture Trustee in
writing that such payment is made under this Guarantee for such purpose.

            3. No Subrogation. Notwithstanding any payment or payments made by
the Guarantor hereunder or any set-off or application of funds of the Guarantor
by any Noteholder,

                                      -3-
<PAGE>
the Guarantor shall not be entitled to exercise or enforce by way of subrogation
any rights of the Indenture Trustee or any Noteholder against the Borrower or
any other Person or any collateral security or guarantee or right of offset held
by the Indenture Trustee or any Noteholder for the payment of the Guaranteed
Obligations, nor shall the Guarantor, in its capacity as Guarantor, seek or be
entitled to seek any contribution or reimbursement from the Borrower or any
other Person in respect of payments made by the Guarantor hereunder, until all
amounts owing to the Indenture Trustee and the Noteholders by the Borrower on
account of the Guaranteed Obligations and all amounts owing hereunder are
indefeasibly paid in full. If any amount shall be paid to the Guarantor on
account of such subrogation rights at any time when all of the Guaranteed
Obligations and all amounts owing hereunder shall not have been paid in full,
such amount shall be held by the Guarantor in trust for the Indenture Trustee
and the Noteholders, segregated from other funds of the Guarantor, and shall,
forthwith upon receipt by the Guarantor, be turned over to the Indenture Trustee
in the exact form received by the Guarantor (duly indorsed by the Guarantor to
the Indenture Trustee, if required), to be applied against the Guaranteed
Obligations, whether matured or unmatured, in such order as the Indenture
Trustee may determine in accordance with the Indenture.

            4. Amendments, etc. with respect to the Guaranteed Obligations;
Waiver of Rights. The Guarantor shall remain obligated hereunder notwithstanding
that, without any reservation of rights against the Guarantor and without notice
to or further assent by the Guarantor, any demand for payment of any of the
Guaranteed Obligations made by the Indenture Trustee or any Noteholder may be
rescinded by such party and any of the Guaranteed Obligations continued, and the
Guaranteed Obligations, or the liability of any other party upon or for any part
thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the Indenture Trustee or any Noteholder, and the Indenture, the Note
Purchase Agreements and the other Operative Agreements may be amended, modified,
supplemented or terminated, in whole or in part, as the Indenture Trustee (or
the Required Holders, as the case may be) may deem advisable from time to time,
and any collateral security, guarantee or right of offset at any time held by
the Indenture Trustee or any Noteholder for the payment of the Guaranteed
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Indenture Trustee nor any Noteholder shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Guaranteed Obligations or for this Guarantee or any property subject thereto.
When making any demand hereunder against the Guarantor, the Indenture Trustee or
any Noteholder may, but shall be under no obligation to, make a similar demand
on the Borrower or any other guarantor, and any failure by the Indenture Trustee
or any Noteholder to make any such demand or to collect any payments from the
Borrower or any other guarantor or any release of the Borrower or such other
guarantor shall not relieve the Guarantor, and shall not impair or affect the
rights and remedies, express or implied, or as a matter of law, of the Indenture
Trustee or any Noteholder against the Guarantor. For the purposes hereof
"demand" shall include the commencement and continuance of any legal
proceedings.

            5. Guarantee Absolute and Unconditional. The Guarantor waives any
and all notice of the creation, renewal, extension or accrual of any of the
Guaranteed Obligations and notice of or proof of reliance by the Indenture
Trustee or any Noteholder upon this Guarantee or acceptance of this Guarantee;
the Guaranteed Obligations, and any of them, shall conclusively be deemed to
have been created, contracted or incurred, or renewed, extended, amended or
waived,

                                      -4-
<PAGE>
in reliance upon this Guarantee; and all dealings between the Borrower and the
Guarantor, on the one hand, and the Indenture Trustee and the Noteholders, on
the other hand, likewise shall be conclusively presumed to have been had or
consummated in reliance upon this Guarantee. The Guarantor waives diligence,
presentment, protest, demand for payment and notice of default or nonpayment to
or upon the Borrower or the Guarantor with respect to the Guaranteed
Obligations. The Guarantor understands and agrees that this Guarantee shall be
construed as a continuing, absolute and unconditional guarantee and primary
obligation and surety of payment and performance without regard to (a) the
validity, regularity or enforceability of the Notes, the Indenture, the Note
Purchase Agreements or any other Operative Agreement, any of the Guaranteed
Obligations or any other collateral security therefor or guarantee or right of
offset with respect thereto at any time or from time to time held by the
Indenture Trustee or any Noteholder, (b) any defense, set-off or counterclaim
(other than a defense of payment or performance) which may at any time be
available to or be asserted by the Borrower or the Guarantor against the
Indenture Trustee or any Noteholder, or (c) any other circumstance whatsoever
(with or without notice to or knowledge of the Borrower or the Guarantor) that
constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrower from the Guaranteed Obligations, or of the Guarantor
under this Guarantee, in bankruptcy or in any other instance. When pursuing its
rights and remedies hereunder against the Guarantor, the Indenture Trustee and
any Noteholder may, but shall be under no obligation to, pursue such rights and
remedies as it may have against the Borrower or any other Person or against any
collateral security or guarantee for the Guaranteed Obligations or any right of
offset with respect thereto, and any failure by the Indenture Trustee or any
Noteholder to pursue such other rights or remedies or to collect any payments
from the Borrower or any such other Person or to realize upon any such
collateral security or guarantee or to exercise any such right of offset, or any
release of the Borrower or any such other Person or any such collateral
security, guarantee or right of offset, shall not relieve the Guarantor of any
liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Indenture
Trustee and the Noteholders against the Guarantor. This Guarantee shall remain
in full force and effect and be binding in accordance with and to the extent of
its terms upon the Guarantor and the successors and assigns thereof, and shall
inure to the benefit of the Indenture Trustee, the Noteholders and their
respective successors, indorsees, transferees and assigns, until all the
Guaranteed Obligations and the obligations of the Guarantor under this Guarantee
shall have been satisfied by indefeasible payment in full, notwithstanding that
from time to time during the term of the Indenture and the Note Purchase
Agreements the Borrower may be free from any Guaranteed Obligations.

            6. Reinstatement. This Guarantee shall continue to be effective, or
be reinstated, as the case may be, if at any time payment, or any part thereof,
of any of the Guaranteed Obligations is rescinded or must otherwise be restored
or returned by the Indenture Trustee or any Noteholder upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or the
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Borrower or the
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made.

            7. Payments. The Guarantor hereby guarantees that payments hereunder
will be paid by the paid to the Indenture Trustee without set-off or
counterclaim in Dollars at the office of the Indenture Trustee located at One
Metropolitan Square, Suite 3900, 211 North

                                      -5-
<PAGE>
Broadway, St. Louis, MO 63102 which shall be distributed in accordance with
Articles 6 and 8 of the Indenture, as applicable.

            8. Representations; Warranties. In order to induce the Purchasers to
enter into the Series A Note Purchase Agreement and to purchase the Series A
Notes (and, if any Series B Notes are issued and sold, to induce the purchasers
thereof to purchase any such Series B Notes under the Series B Note Purchase
Agreement), the Guarantor hereby represents and warrants to the Indenture
Trustee and each Noteholder as of the Closing Date, as follows, all of which
shall survive the execution and delivery of this Guarantee, the Indenture and
the Note Purchase Agreements and the purchase of the Notes:

              8.1 Financial Condition. (i) The audited consolidated balance
      sheet of the Guarantor at the end of its most recent fiscal year and the
      related consolidated statements of income and comprehensive income, of
      changes in equity and of cash flows of the Guarantor for the fiscal period
      ended on such date, reported on by its independent public accountants, and
      (ii) the unaudited consolidated balance sheet of the Guarantor at the end
      of its most recent fiscal quarter and the related consolidated statements
      of income and cash flows of the Guarantor for the portion of the fiscal
      period ended on such date, certified as complete and correct and prepared
      in accordance with GAAP (subject to normal year-end adjustments) by the
      chief financial officer or treasurer of the Guarantor, copies of each of
      which have heretofore been furnished to each Noteholder, are complete and
      correct and present fairly (except, with respect to interim statements,
      for normal year end adjustments) the consolidated financial position of
      the Guarantor as of such dates, and the consolidated results of operations
      and cash flows for the fiscal periods then ended and, in the case of the
      statements referred to in the foregoing clause (ii), the portion of the
      fiscal year through such date. All such financial statements, including
      the related schedules and notes thereto in the case of statements referred
      to in the foregoing clause (ii), have been prepared in accordance with
      GAAP applied consistently throughout the periods involved (except, with
      respect to interim statements, for normal year-end adjustments and that
      such interim statements may be condensed and exclude detailed footnote
      disclosure and except as concurred with such accountants or such chief
      financial officer, as the case may be, and as disclosed therein). The
      Guarantor did not, as of the date of any such financial statements, have
      any material obligation, contingent or otherwise, which was not reflected
      in the foregoing statements or in the notes thereto and which,
      individually or in the aggregate, could reasonably be expected to have a
      Material Adverse Effect.

              8.2 No Material Change. Since the date of the most recent
      financial statements identified in Section 8.1(i) (i) there has been no
      occurrence which, individually or in the aggregate, could reasonably be
      expected to have a Material Adverse Effect, and (ii) other than as
      disclosed in any financial statements delivered hereunder pursuant to
      Section 8.1, the Guarantor has not, since such date, incurred any material
      obligation, contingent or otherwise, which, individually or in the
      aggregate, could reasonably be expected to have a Material Adverse Effect.

              8.3 Corporate Existence; Compliance with Law. The Guarantor (a) is
      a non-stock membership corporation duly organized, validly existing and in
      good standing under the laws of the jurisdiction of its incorporation, (b)
      has the corporate

                                      -6-
<PAGE>
      power and authority and the legal right to own and operate its
      property, to lease the property it operates and to conduct the business in
      which it is currently engaged (except to the extent that the failure to
      possess such corporate power and authority and such legal right,
      individually or in the aggregate, could not reasonably be expected to have
      a Material Adverse Effect), (c) is duly qualified as a foreign corporation
      and in good standing under the laws of each jurisdiction where its
      ownership, lease or operation of property or the conduct of its business
      requires such qualification, except where the failure to be so qualified,
      individually or in the aggregate, could not reasonably be expected to have
      a Material Adverse Effect and (d) is in compliance with all Legal
      Requirements (including, without limitation, CERCLA, any so-called
      "Superfund" or "Superlien" law, or any applicable federal, state, local or
      other statute, law, ordinance, code, rule, regulation, order or decree
      regulating, relating to, or imposing liability or standards of conduct
      concerning, any Hazardous Substances), except to the extent that the
      failure to comply therewith, individually or in the aggregate, could not
      reasonably be expected to have a Material Adverse Effect.

              8.4 Corporate Power: Authorization. The Guarantor has the
      corporate power and authority and the legal right to make, deliver and
      perform the Operative Agreements to which it is a party. The Guarantor has
      taken all necessary corporate action to authorize the execution, delivery
      and performance of the Operative Agreements to which it is a party. No
      consent or authorization of, or filing with, any Person (including,
      without limitation, any Governmental Authority) is required in connection
      with the execution, delivery or performance by the Guarantor or the
      validity or enforceability against the Guarantor of any Operative
      Agreement to which it is a party.

              8.5 Enforceable Obligations. Each of the Operative Agreements to
      which it is a party has been duly executed and delivered on behalf of the
      Guarantor and each of such Operative Agreements constitutes the legal,
      valid and binding obligation of the Guarantor, enforceable against the
      Guarantor in accordance with its terms, except as such enforceability may
      be limited by applicable bankruptcy, insolvency, reorganization,
      moratorium, or similar laws affecting creditors' rights generally and by
      general principles of equity (regardless of whether enforcement is sought
      in a proceeding in equity or at law).

              8.6 No Legal Bar. The performance of each Operative Agreement to
      which it is a party will not violate any Legal Requirement or any
      Contractual Obligation applicable to or binding upon the Guarantor or any
      of its properties or assets, which violations, individually or in the
      aggregate, could reasonably be expected to have a Material Adverse Effect,
      and will not result in the creation or imposition (or the obligation to
      create or impose) any Lien (other than Liens created under the Security
      Documents) on any of its properties or assets pursuant to any Legal
      Requirement applicable to it or any of its Contractual Obligations.

              8.7 No Material Litigation. Except as disclosed in Schedule 8.7,
      no litigation, investigation known to the Guarantor or proceeding of or by
      any Governmental Authority or any other Person is pending or, to its
      knowledge, threatened against the Guarantor (a) with respect to the
      validity, binding effect or enforceability of any Operative Agreement and
      the transactions contemplated thereby, or (b) which,

                                      -7-
<PAGE>
      individually or in the aggregate, could reasonably be expected to
      have a Material Adverse Effect.

              8.8 Investment Company Act. The Guarantor is not an "investment
      company" or a company "controlled" by an "investment company" (as each of
      the quoted terms is defined or used in the Investment Company Act of 1940,
      as amended).

              8.9 Federal Regulation. No part of the proceeds of the sale of the
      Notes will be used for any purpose which violates, or which would be
      inconsistent with, the provisions of Regulation T, U or X of the Federal
      Reserve Board. The Guarantor is not engaged and will not engage,
      principally or as one of its important activities, in the business of
      extending credit for the purpose of "purchasing" or "carrying" any "margin
      stock" within the respective meanings of the quoted terms under said
      Regulation U.

              8.10 No Default. The Guarantor is not in default in the payment or
      performance of any of its Contractual Obligations in any respect which,
      individually or in the aggregate, could reasonably be expected to have a
      Material Adverse Effect. The Guarantor is not in default under any order,
      award or decree of any Governmental Authority or arbitrator binding upon
      or affecting it or by which any of its properties or assets may be bound
      or affected in any respect which default, individually or in the
      aggregate, could reasonably be expected to have a Material Adverse Effect,
      and no such order, award or decree, individually or in the aggregate,
      could reasonably be expected to have a Material Adverse Effect.

              8.11 No Burdensome Restrictions. The Guarantor is neither a party
      to nor is bound by any Contractual Obligation or subject to any Legal
      Requirement or other corporate restriction which, individually or in the
      aggregate, could reasonably be expected to have a Material Adverse Effect.

              8.12 Taxes. The Guarantor has filed or caused to be filed or has
      timely requested an extension to file or has received an approved
      extension to file all tax returns which, to the knowledge of the
      Guarantor, are required to have been filed, and has paid all taxes shown
      to be due and payable on said returns or extension requests or on any
      assessments made against it or any of its property and all other taxes,
      fees or other charges imposed on it or any of its property by any
      Governmental Authority (other than those the amount or validity of which
      is currently being contested in good faith by appropriate proceedings and
      with respect to which reserves in conformity with GAAP have been provided
      in the books of the Guarantor), except where the failure to make or pay
      any such filings or taxes, fees or charges, individually or in the
      aggregate, could not reasonably be expected to have a Material Adverse
      Effect; and, to the knowledge of the Guarantor, no claims are being
      asserted with respect to any such taxes, fees or other charges (other than
      those the amount or validity of which is currently being contested in good
      faith by appropriate proceedings and with respect to which reserves in
      conformity with GAAP have been provided in the books of the Guarantor),
      except where the failure to pay any such taxes, fees or other charges,
      individually or in the aggregate, could not reasonably be expected to have
      a Material Adverse Effect. The federal income tax liabilities of the
      Guarantor have been determined by the United States Internal Revenue

                                      -8-
<PAGE>
      Service and paid for all fiscal years up to and including the
      fiscal year ended December 31, 1998.

              8.13 Ownership of Property: Liens. The Guarantor has good and
      marketable title to, or valid and subsisting leasehold interests in, all
      its real property, and good title to all its material other property,
      except to the extent the failure to have such good title or valid
      leasehold interest, individually or in the aggregate, could not reasonably
      be expected to have a Material Adverse Effect; and none of such property
      is subject, except as permitted hereunder or under the other Operative
      Agreements and except as, individually or in the aggregate, could not
      reasonably be expected to have a Material Adverse Effect, to any Lien
      (including, without limitation, federal, state and other tax Liens).

              8.14 ERISA. No "prohibited transaction" (as defined in Section 406
      of ERISA or Section 4975 of the Code) or "accumulated funding deficiency"
      (as defined in Section 302 of ERISA) or Reportable Event (other than a
      Reportable Event with respect to which the 30-day notice requirement under
      Section 4043 of ERISA has been waived) has occurred during the five years
      preceding each date on which this representation is made or deemed made,
      or will occur, after giving effect to the transactions contemplated by the
      Operative Agreements, with respect to any Plan in any case the
      consequences of which, individually or in the aggregate, could reasonably
      be expected to have a Material Adverse Effect. The present value of all
      accrued benefits under each Single Employer Plan maintained by the
      Guarantor or a Commonly Controlled Entity (based on those assumptions used
      to fund such Plan) did not, as of the most recent annual valuation date in
      respect of each such Plan, exceed the fair market value of the assets of
      the Plan (including for these purposes accrued but unpaid contributions)
      allocable to such benefits by an amount which, individually or in the
      aggregate, could reasonably be expected to have a Material Adverse Effect.
      The liability to which the Guarantor or any Commonly Controlled Entity
      would become subject under ERISA if the Guarantor or any such Commonly
      Controlled Entity were to withdraw completely from all Multiemployer Plans
      as of the valuation date most closely preceding the date hereof would not
      have a Material Adverse Effect. No Multiemployer Plan is either in
      Reorganization or Insolvent in any case the consequences of which,
      individually or in the aggregate, could reasonably be expected to have a
      Material Adverse Effect.

              8.15 Solvency. The Guarantor has received reasonably equivalent
      value in exchange for guaranteeing the Guaranteed Obligations. The net
      cash flow and the fair saleable value of the business and assets of the
      Guarantor, upon giving effect to the transactions contemplated by the
      Operative Agreements, shall be not less than the amount that shall be
      required to pay the probable liabilities of the Guarantor (including the
      Guaranteed Obligations and all contingent, fixed, subordinated,
      unsubordinated, matured, unmatured, liquidated and unliquidated
      liabilities) on existing debts as they may become absolute and matured.
      The Guarantor is not and, upon giving effect to the transactions
      contemplated by the Operative Agreements, shall not be "insolvent" (as
      defined in Title 11 of the United States Code or under any applicable
      state fraudulent conveyance or transfer statute, in each case as in effect
      from time to time), and shall not be engaged in any business or
      transaction, or about to engage in any business or transaction, for which
      the Guarantor has an unreasonably small capital, and the Guarantor has no
      intent (a) to

                                      -9-
<PAGE>
      hinder, delay or defraud any Person to which the Guarantor is, or
      anticipates it shall become, indebted or (b) to incur indebtedness that
      would be beyond its ability to pay as such indebtedness matures.

              8.16 Disclosure. The Guarantor, through the Arranger, has
      delivered to each Purchaser a copy of a Confidential Offering Memorandum
      (the "Memorandum") related to the transactions contemplated by the
      Operative Agreements. The Memorandum fairly describes, in all material
      respects, the general nature of the business and principal properties of
      the Guarantor. The Memorandum, this Guarantee and the other Operative
      Agreements and any other materials delivered by or on behalf of the
      Guarantor, taken as a whole, do not contain any untrue statement of a
      material fact or omit to state any material fact necessary to make the
      statements therein not misleading in light of the circumstances under
      which they were made. There is no fact known to the Guarantor that,
      individually or in the aggregate, could reasonably be expected to have a
      Material Adverse Effect and that has not been set forth in the Memorandum
      or in the Operative Agreements delivered by or on behalf of the Guarantor.

         9. Affirmative Covenants of the Guarantor. The Guarantor hereby agrees
that so long as this Guarantee is in effect and until the Guaranteed Obligations
and all amounts owing hereunder are indefeasibly paid in full it will:

            9.1 Financial Statements. Furnish to the Indenture Trustee (with
    sufficient copies for each Noteholder):

              (a) as soon as available, but in any event within 120 days after
      the end of each fiscal year of the Guarantor, a copy of the consolidated
      balance sheet of the Guarantor as at the end of such year and the related
      consolidated statements of income, of changes in equity and of cash flows
      for such year, setting forth in each case in comparative form the figures
      for the previous year, reported on (without a "going concern" or like
      qualification or exception or any qualification arising out of the scope
      of the audit) by independent certified public accountants of nationally
      recognized standing; and

              (b) as soon as available, but in any event not later than 60 days
      after the end of each of the first three quarterly periods of each fiscal
      year of the Guarantor, the unaudited consolidated balance sheet of the
      Guarantor as at the end of such quarter and the related unaudited
      consolidated statements of income, of changes in equity and of cash flows
      of the Guarantor for the portion of the fiscal year through the end of
      such quarter, setting forth in each case in comparative form the figures
      for the previous year, certified by a Responsible Officer as being fairly
      stated in all material respects (subject to normal year-end audit
      adjustments);

all of which financial statements shall be complete and correct in all material
respects (subject, in the case of interim statements, to normal year-end audit
adjustments) and shall be prepared in reasonable detail (except that interim
statements may be condensed and may exclude detailed footnote disclosure) and in
accordance with GAAP applied consistently throughout the periods reflected
therein and with prior periods (except as concurred with such accountants or a
Responsible Officer, as the case may be, and disclosed therein and except that
interim financial

                                      -10-
<PAGE>
statements need not be restated for changes in accounting principles which
require retroactive application, and operations which have been discontinued (as
defined in Accounting Principles Board Opinion No. 30) during the current year
need not be shown in interim financial statements as such either for the current
period or comparable prior period). In the event the Guarantor changes its
accounting methods because of changes in GAAP, or any change in GAAP occurs
which increases or diminishes the protection and coverage afforded to the
Noteholders under current GAAP accounting methods, the Guarantor or the
Indenture Trustee, as the case may be, may request of the other parties to this
Guarantee an amendment of the financial covenants contained in this Guarantee to
reflect such changes in GAAP and to provide the Noteholders with protection and
coverage equivalent to that existing prior to such changes in accounting methods
or GAAP, and each of the Guarantor, the Indenture Trustee and the Noteholders
agree to consider such request in good faith.

            9.2 Certificates; Other Information. Furnish to the Indenture
    Trustee (with sufficient copies for each Noteholder which shall be made
    available by the Indenture Trustee to any Noteholder upon request):

             (a) concurrently with the delivery of the financial statements
        referred to in Section 9.1(a), a letter from the Guarantor's independent
        certified public accountants reporting on such financial statements
        stating that in making the examination necessary to express their
        opinion on such financial statements no knowledge was obtained of any
        failure by the Guarantor to comply with Section 10.1 hereof, except as
        specified in such letter;

             (b) concurrently with each delivery of the financial statements
        referred to in Sections 9.1(a) and (b), a certificate of a Responsible
        Officer of the Guarantor (i) stating that such officer has reviewed and
        is familiar with this Guarantee and the other Operative Agreements and
        that, to the best of such officer's knowledge, the Guarantor has
        observed or performed all of its covenants and other agreements, and
        satisfied every condition, contained in this Guarantee, or in the other
        Operative Agreements to be observed, performed or satisfied by it, and
        that such officer has obtained no knowledge of any default under this
        Guarantee or any Lease Default or Lease Event of Default except as
        specified in such certificate, (ii) showing in detail as of the end of
        the related fiscal period the figures and calculations supporting such
        statement in respect of Section 10.1;

             (c) promptly upon receipt thereof, copies of all final reports
        submitted to the Guarantor by independent certified public accountants
        in connection with each annual, interim or special audit of the books of
        the Guarantor made by such accountants;

             (d) promptly upon their becoming available, copies of all financial
        statements, reports, notices and proxy statements sent or made available
        generally by the Guarantor and all regular and periodic reports and all
        final registration statements and final prospectuses, if any, filed by
        the Guarantor with any securities exchange or with the Securities and
        Exchange Commission or any Governmental Authority succeeding to any of
        its functions; and

                                      -11-
<PAGE>
             (e) promptly, such additional financial and other information as
        any Noteholder may from time to time reasonably request.

            9.3 Payment of Obligations. Pay, discharge or otherwise satisfy at
or before maturity or before they become delinquent, as the case may be, all of
its obligations and liabilities of whatever nature, except (a) when the amount
or validity thereof is currently being contested in good faith by appropriate
proceedings and adequate reserves in conformity with GAAP with respect thereto
have been established on the books of the Guarantor, (b) for delinquent
obligations which, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect and (c) for trade and other accounts
payable in the ordinary course of business in accordance with customary trade
terms and which are not overdue for a period of more than 120 days (or any
longer period if longer payment terms are accepted in the ordinary course of
business) or, if overdue for more than 120 days (or such longer period), as to
which a good faith dispute exists and is diligently being contested and adequate
reserves in conformity with GAAP have been established on the books of the
Guarantor.

            9.4 Conduct of Business and Maintenance of Existence. Continue to
engage in business of the same general type as now conducted by it, and
preserve, renew and keep in full force and effect its corporate existence and
take all reasonable action to maintain all rights, privileges and franchises
necessary or desirable in the normal conduct of its business except for rights,
privileges and franchises the loss of which, individually or in the aggregate,
could not reasonably be expected to have a Material Adverse Effect; and comply
with all applicable Legal Requirements except to the extent that the failure to
comply therewith, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.

            9.5 Maintenance of Property: Insurance. (a) Keep all property useful
and necessary in its business (other than the Facility, for which the provisions
of the Lease shall apply) in good working order and condition (ordinary wear and
tear excepted); and

            (b) Maintain with financially sound and reputable insurance
        companies insurance on all its property (other than the Facility, for
        which the provisions of the Lease shall apply) in at least such amounts
        and with only such deductibles as are usually maintained by, and against
        at least such risks as are usually insured against in the same general
        area by, companies engaged in the same or a similar business; provided
        that the Guarantor may implement programs of self insurance in the
        ordinary course of business and in accordance with industry standards
        for a company of similar size so long as reserves are maintained in

Noteholder:

        Multiemployer Plan, the Reorganization or Insolvency of such Plan, in
        each of the foregoing cases which, individually or in the aggregate,

        Noteholder whichever of the following may be applicable: (A) a
        certificate of the controller or treasurer of the Guarantor setting
        forth details as to such Reportable Event and the action that the
        Guarantor or such Commonly Controlled Entity proposes to take with
        respect thereto, together with a copy of any notice of such Reportable
        Event that may be required to be filed

                                      -13-
<PAGE>
        with PBGC, or (B) any notice delivered by PBGC evidencing its
        intent to institute such proceedings or any notice to PBGC that such
        Plan is to be terminated, as the case may be; and

             (e) of any event that, individually or in the aggregate, could
        reasonably be expected to have a Material Adverse Effect.

      Each notice pursuant to this Section 9.7 shall be accompanied by a
      statement of the controller or treasurer of the Guarantor setting forth
      details of the occurrence referred to therein and stating what action the
      Guarantor proposes to take with respect thereto.

            10. Negative Covenants. The Guarantor hereby agrees that so long as
this Guarantee is in effect and until the Guaranteed Obligations and all amounts
owing hereunder are indefeasibly paid in full, the Guarantor shall not, at any
time, directly or indirectly:

                10.1 Consolidated Net Worth. Permit Consolidated Net Worth at
        any time to be less than (a) $182,108,000 plus (b) 50% of its
        Consolidated Net Income (but only if positive) for each fiscal quarter,
        for the period beginning on the first day of the first full fiscal
        quarter following the Closing Date and ending on the last day of the
        fiscal quarter for which financial statements have been most recently
        delivered to the Indenture Trustee pursuant to Section 9.1.

                10.2 Fundamental Changes. Consolidate with or merge with, or
        convey, transfer or lease all or substantially all of its assets in a
        single transaction or series of transactions to, any Person; provided
        that the foregoing restrictions shall not apply to the consolidation or
        merger of the Guarantor with, or conveyance, transfer or lease of all or
        substantially all of the assets of the Guarantor in a single transaction
        or series of transactions to, any Person so long as:

                  (a) the successor formed by such consolidation or the survivor
        of such merger or the Person that acquires by conveyance, transfer or
        lease all or substantially all of the assets of the Guarantor as an
        entirety, as the case may be (the "Successor Guarantor"), shall be a
        solvent corporation organized under the laws of the United States of
        America, any state thereof or the District of Columbia;

                  (b) each such corporation shall have executed and delivered to
        the Indenture Trustee and the Noteholders its assumption of the due and
        punctual performance and observance of each covenant and condition of
        this Guarantee and each other Operative Agreement to which the Guarantor
        is a party;

                  (c) after giving effect to such transaction, the respective
        senior unsecured debt credit ratings of the Successor Guarantor by S&P
        and Moody's shall be no less than such ratings immediately before giving
        effect to such transaction; and

                  (d) immediately before and after giving effect to such
        transaction, no Indenture Default or Indenture Event of Default or any
        default under this Guarantee would exist.

                  10.3 ERISA. Use moneys from any Plan established by the
        Guarantor or for the benefit of the Guarantor's employees to perform any
        of the Guarantor's obligations under this Guarantee or any other
        Operative Agreements, nor will the Guarantor transfer its interests in
        the Collateral to any such Plan. The Guarantor will not, and will not
        permit any ERISA Affiliate to, withdraw from any Multiemployer Plan or
        permit any Plan maintained by it or for the benefit of its employees to
        be terminated if such withdrawal or termination would result in
        withdrawal liability (as described in Part I of Subtitle E of Title IV
        of ERISA) or the imposition of a Lien on the Collateral pursuant to
        Section 4068 of ERISA.

            11. Authority of Indenture Trustee. The Guarantor acknowledges that
the rights and responsibilities of the Indenture Trustee under this Guarantee
with respect to any action taken by the Indenture Trustee or the exercise or
non-exercise by the Indenture Trustee of any option, right, request, judgment or
other right or remedy provided for herein or resulting or arising out of this
Guarantee shall, as between the Indenture Trustee and the Noteholders, be
governed by the Indenture and by such other agreements with respect thereto as
may exist from time to time among them, but, as between the Indenture Trustee
and the Guarantor, the Indenture Trustee shall be conclusively presumed to be
acting as agent for the Noteholders with full and valid authority so to act or
refrain from acting, and the Guarantor shall not be under any obligation, or
entitlement, to make any inquiry respecting such authority.

            12. Notices. All notices, requests and demands to or upon the
Indenture Trustee, any Noteholder or the Guarantor to be effective shall be in
writing (including by telecopy or telex), and, unless otherwise expressly
provided herein, shall be deemed to have been duly given or made when delivered
in person or by mail, postage prepaid, by Federal Express or other reliable
24-hour delivery service, or, in the case of facsimile, when received, addressed
as follows:

            (a) if to the Indenture Trustee or any Noteholder, at its address or
transmission number for notices provided in Section 11.5 of the Indenture and
Schedule A of the Note Purchase Agreements, respectively; and

            (b) if to the Guarantor, at its address or transmission number for
notices set forth opposite its signature below.

            The Indenture Trustee, each Noteholder and the Guarantor may change
its address and transmission numbers for notices by notice in the manner
provided in this Section 12.

                                      -15-

            13. Severability. Any provision of this Guarantee which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            14. Integration. This Guarantee represents the agreement of the
Guarantor with respect to the subject matter hereof and there are no promises or
representations by the Indenture Trustee or any Noteholder relative to the
subject matter hereof not reflected herein.

            15. Amendments in Writing; No Waiver; Cumulative Remedies. (a) None
of the terms or provisions of this Guarantee may be waived, amended,
supplemented or otherwise modified except as provided in Section 11.1 of the
Indenture.

            (b) Neither the Indenture Trustee nor any Noteholder shall by any
act (except by a written instrument pursuant to Section 15(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Indenture Default or Indenture Event of
Default or in any breach of any of the terms and conditions hereof. No failure
to exercise, nor any delay in exercising, on the part of the Indenture Trustee
or any Noteholder, any right, power or privilege hereunder shall operate as a
waiver thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Indenture Trustee or any
Noteholder of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Indenture Trustee or such
Noteholder would otherwise have on any future occasion.

            (c) The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

            16. Section Headings. The section headings used in this Guarantee
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

            17. Successors and Assigns. This Guarantee shall be binding upon the
successors and assigns of the Guarantors and shall inure to the benefit of the
Indenture Trustee, the Noteholders and their successors and assigns.

            18. SUBMISSION TO JURISDICTION: WAIVERS. (a) THE GUARANTOR HEREBY
IRREVOCABLY AND UNCONDITIONALLY:

                (i) SUBMITS IN ALL LEGAL ACTIONS OR PROCEEDINGS RELATING TO THIS
        GUARANTEE OR ANY OTHER OPERATIVE AGREEMENT TO WHICH IT IS A PARTY, OR
        FOR RECOGNITION AND ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF, TO
        THE NON-EXCLUSIVE GENERAL JURISDICTION OF THE SUPREME COURT OF THE STATE
        OF NEW YORK AND THE APPELLATE COURTS THEREOF AND THE FEDERAL COURT FOR
        THE SOUTHERN DISTRICT OF NEW YORK;

                                      -16-
<PAGE>

                (ii) CONSENTS THAT ANY SUCH ACTION OR PROCEEDING MAY BE BROUGHT
        IN SUCH COURT, WAIVES ANY OBJECTION THAT IT MAY HAVE NOW OR HEREAFTER TO
        THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT AND WAIVES
        ANY OBJECTION THAT SUCH ACTION OR PROCEEDING IN ANY SUCH COURT WAS
        BROUGHT IN AN INCONVENIENT FORUM AND AGREES NOT TO PLEAD, CLAIM OR
        ASSERT THE SAME;

                (iii) AGREES THAT SERVICE OF PROCESS IN ANY SUCH ACTION OR
        PROCEEDING IN ANY SUCH COURT MAY BE EFFECTED BY MAILING A COPY THEREOF
        BY REGISTERED OR CERTIFIED MAIL (OR ANY SUBSTANTIALLY SIMILAR FORM OF
        MAIL), POSTAGE PREPAID TO, OR BY PERSONAL SERVICE AT, ITS ADDRESS SET
        FORTH HEREIN OR SUCH OTHER ADDRESS OF WHICH THE INDENTURE TRUSTEE SHALL
        HAVE BEEN NOTIFIED PURSUANT HERETO, WHETHER OR NOT SUCH ADDRESS BE
        WITHIN THE JURISDICTION OF ANY SUCH COURT;

                (iv) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT
        SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT
        THE RIGHT OF THE INDENTURE TRUSTEE (AND NOT OF THE GUARANTOR) TO SUE IN
        ANY OTHER JURISDICTION; AND

                (v) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY
        RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LEGAL ACTION OR PROCEEDING
        RELATING TO ANY OPERATIVE AGREEMENT OR RELATED DOCUMENT OR TRANSACTION
        ANY SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES.

        (b) THE GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY
JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS GUARANTEE OR ANY OTHER
OPERATIVE AGREEMENT AND FOR ANY COUNTERCLAIM THEREIN.

        (c) THE GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE
RIGHT TO ASSERT, ARGUE OR RAISE, IN ANY ACTION BROUGHT BY THE INDENTURE TRUSTEE
AGAINST THE GUARANTOR UNDER THIS GUARANTEE, THAT THE INDENTURE TRUSTEE OR THE
NOTEHOLDERS STRUCTURED THE TRANSACTION CONTEMPLATED BY THE OPERATIVE AGREEMENTS
IN SUCH A MANNER PRIMARILY TO CIRCUMVENT ANY ONE-FORM-OF-ACTION OR
ANTI-DEFICIENCY LAWS.

        (d) The Guarantor hereby waives all of the Guarantor's rights of
subrogation, reimbursement, contribution or in respect of suretyship and any
other rights and defenses available to the Guarantor, including (a) any defenses
the Guarantor may have to the obligations undertaken by the Guarantor in this
Guarantee by reason of an election of remedies by any Noteholder and (b) any
rights or defenses the Guarantor may have by reason of protection afforded by
the Borrower with respect to the obligations guaranteed hereby pursuant to the

                                      -17-
<PAGE>
antideficiency, bankruptcy, insolvency or other similar laws limiting or
discharging the Borrower's Indebtedness. The Guarantor's waiver of defenses
under clause (c) above is made even though an election of remedies by any
Noteholder, such as a nonjudicial foreclosure with respect to security for a
guaranteed obligation, may extinguish the Guarantor's rights of subrogation and
reimbursement against the Borrower. The foregoing waivers shall not be deemed a
waiver of the defense that the Guaranteed Obligations have been indefeasibly
paid in full. To the extent of any inconsistency between the provisions of this
Section 18(d) and Section 3, the provisions of Section 3 shall control.

        19. GOVERNING LAW. THIS GUARANTEE SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF YORK, WITHOUT REGARD
TO CONFLICTS OF LAWS PRINCIPLES WHICH MAY REQUIRE THE APPLICATION OF LAWS OF
ANOTHER STATE.

        20. Right of Set-Off. In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such
rights, upon the occurrence and during the continuance of an Indenture Event of
Default, the Indenture Trustee and each Noteholder are hereby authorized at any
time or from time to time, without presentment, demand, protest or other notice
of any kind to the Borrower, the Guarantor or any other Person, any such notice
being hereby expressly waived, to set off and to appropriate and apply any and
all deposits (general or special) and any other Indebtedness at any time held or
owing by the Indenture Trustee or such Noteholder (including, without
limitation, by branches and agencies of the Indenture Trustee or such Noteholder
wherever located) to or for the credit or the account of the Guarantor against
and on account of the obligations and liabilities of the Guarantor hereunder or
under any of the other Operative Agreements, and all other claims if any nature
or description arising out of or connected with this Guarantee or any other
Operative Agreement, irrespective of whether the Indenture Trustee or such
Noteholder shall have made any demand hereunder and although said obligations,
liabilities or claims, or any of them, shall be contingent or unmatured.

                                      -18-

            IN WITNESS WHEREOF, the undersigned has caused this Guarantee to be
