ITEM 5.           OTHER EVENTS.

GROUND BREAKING FOR NEW CORPORATE HEADQUARTERS AND CENTRAL WAREHOUSE FACILITY

         On January 4, 1999, the ground breaking for the construction of the
Company's new corporate headquarters and warehouse facility (the "New Facility")
took place. The New Facility, which will be located on a 41 acre parcel in the
City of Miramar, Florida, will contain approximately 630,000 square feet of
space and consist of two buildings. One building, which will contain
approximately 545,000 square feet, will consolidate the operations of the
Company's aircraft spare parts redistribution business, as well as serve as the
corporate headquarters for the Company's distribution services, maintenance,
repair and overhaul ("MR&O"), leasing and manufacturing businesses. The other
building, which will contain approximately 85,000 square feet, will be used as
office and warehouse space by the Company's subsidiary, Caribe Aviation, Inc.

DEVELOPMENT AND LEASING OF THE NEW FACILITY

         On December 17, 1998, the Company entered into a tax retention
operating lease for the New Facility (the "Lease") with First Security Bank,
National Association, as trustee (the "Trustee") of the Aviation Sales Trust
1998-1 (the "Trust"), as lessor. The Lease has an initial term of five years and
is a triple net lease with annual rent as provided in the Lease. The Lease
contains certain financial covenants regarding the financial performance of the
Company and certain other affirmative and negative covenants which the Company
will be obligated to comply with during the term of the Lease. Substantially all
of the Company's subsidiaries have guaranteed the Company's obligations under
the Lease. Additionally, the Company has an option to acquire the New Facility
at the end of the Lease for an option price as determined in the Lease.
Alternatively, if the Company does not purchase the New Facility at the end of
the Lease, the Company will be obligated to pay certain amounts as provided in
the Lease.

         The development of the New Facility has been financed through a $34.4
million operating lease facility provided by a syndicate of financial
institutions (the "TROL Financing"). Pursuant to the TROL Financing documents,
the Company is obligated to develop the New Facility on behalf of the Trust and
is responsible for the timely completion thereof within an established
construction budget. The Company and substantially all of its subsidiaries have
guaranteed the repayment of $31.2 million of the Trustee's obligations under a
credit agreement with certain lenders (the "Credit Agreement"). The Trust's
obligations under the Credit Agreement are secured by a lien on the real
property and improvements comprising the New Facility and on the fixtures
therein. Further, the Company has posted an irrevocable letter of credit in
favor of the Trustee in the amount of approximately $8.0 million to secure
both the Company's obligations under the Lease and the Trustee's obligations
under the Credit Agreement.

         The foregoing is a summary of certain information contained in the
above-referenced documents. Reference is made to the more detailed information
contained in such documents which are attached hereto as Exhibits 10.1-10.5.

AMENDMENT TO THE COMPANY'S SENIOR CREDIT FACILITY

         On December 15, 1998, the Company entered into an agreement amending
its existing senior credit facility pursuant to the terms of an Amendment No. 4
and Consent to Third Amended and Restated Credit Agreement dated as of October
17, 1997 (the "Fourth Amendment to Credit Facility Agreement"). Under the terms
of the Fourth Amendment to Credit Facility Agreement, the Company's existing
credit facility was amended to allow for the TROL Financing and to make other
non-substantive changes to the Company's amended credit facility.

         The foregoing is a summary of certain information contained in the
above-referenced document. Reference is made to the more detailed information
contained in such document, which is attached hereto as Exhibit 10.6.

IMPACT OF THE YEAR 2000

         Over the last year, the Company has been implementing new management
information ("MIS") systems in order to both allow that the Company's computer
systems, which are an important component of its businesses, to meet the
Company's needs into the foreseeable future and to mitigate the Year 2000 issues
which the Company's management believes could be inherent in the Company's
existing MIS systems. The Company has also grown rapidly over the last year, and
particularly over the last six months, and has expanded its operations beyond
the redistribution of aircraft spare parts into the MR&O of aircraft and
aircraft components and into the manufacturing of aircraft parts for sale to
original equipment manufacturers. Due to its rapid expansion, the Company
recently commenced an assessment of the MIS requirements in all of its
businesses.

         The Year 2000 issue is the potential for system and processing failures
of date-related data and the result of computer-controlled systems using two
digits rather than four to define the applicable year. The Company may be
affected by Year 2000 issues in its own non-compliant information technology
("IT") systems or non-IT systems, as well as by Year 2000 issues related to
non-compliant IT and non-IT systems operated by third parties.

         The following discussion contains forward-looking statements, which are
based upon the Company's expectations and are subject to a number of risks and
uncertainties, many of which are beyond the control of the Company. Should one
or more of these risks or uncertainties materialize, or should the assumptions
underlying these forward looking statements prove incorrect, actual results
could differ significantly and adversely from the results expressed or implied
in these forward looking

                                        3


<PAGE>



statements. The Company does not undertake any obligation to revise these
forward looking statements to reflect future events or circumstances. See also
the cautionary statements contained in the MD & A section of the Company's
Quarterly Report on Form 10-Q for the quarter ended September 30, 1998.

         STATE OF READINESS

         The Company has substantially completed an assessment of its internal
and external (third-party) IT systems and non-IT systems. At this point in its
assessment, which the Company believes is approximately 75% complete (in the
aggregate), other than as described herein, the Company is not currently aware
of any Year 2000 problems relating to its systems or the systems operated by
third parties which would have a material effect on the Company's business,
results of operations or financial condition, without taking into account the
Company's efforts to avoid such problems, although there can be no assurance
thereof. In addition, the Company believes that it is approximately 25% and
15% complete (in the aggregate), respectively, with its Year 2000 remediation
and validation.

         The Company's IT systems consist of software licensed from third
parties and hardware purchased or leased from vendors. The Company is currently
implementing new MIS systems, which are primarily designed to service the
Company's distribution services and manufacturing businesses, including new
software and hardware, which management believes that, once fully implemented,
will be Year 2000 compliant and will meet the requirements of the Company's
distribution services and manufacturing businesses into the foreseeable future.
The Company anticipates the systems for each of the distribution services
operations and the manufacturing operations will be substantially implemented by
the end of the third quarter of 1999, although there can be no assurance
thereof.

         The Company has determined that the MIS system which is currently being
used by its distribution services business is not Year 2000 compliant. If the
implementation of the Company's new MIS system is delayed for any reason beyond
April 1999, the Company may decide to modify its existing MIS system to make it
Year 2000 compliant. The Company believes that such modifications would need to
commence no later than July 1999 for the Company to be in a position to
implement, remediate and validate its existing system, as modified, for Year
2000 compliance prior to January 1, 2000. While the Company has been informed by
its vendors that its existing MIS system can be brought into Year 2000
compliance on a timely basis, there can be no assurance of this fact.

         To date, the Company has determined that some of the MIS systems which
are currently being used by its MR&O businesses are not Year 2000 compliant.
Excluding its TIMCO Greensboro, Lake City and Macon facilities, the Company has
substantially completed its assessment of the hardware and software being used
by its non-heavy maintenance MR&O operations and believes that such systems can
be made Year 2000 compliant by the end of 1999. The Company is still in the
process of conducting an assessment of the Year 2000 compliance of the hardware
and software systems for its TIMCO Greensboro, Lake City and Macon facilities,
which were acquired in 1998. Until such time

                                        4


<PAGE>



as the Company substantially completes such assessment, the Company is unable to
determine the scope of remediation and validation work associated with the IT
and non-IT systems at such facilities.

         The Company has also determined that its MIS systems which are being
used by its manufacturing business are not Year 2000 compliant. The Company has
substantially completed its assessment of the hardware and software being used
by its manufacturing operations and believes that such systems can be made Year
2000 compliant either through replacement of the MIS systems or remediation of
the existing hardware and software of its various manufacturing operations. It
expects to complete such changes prior to the end of 1999.

         Excluding its TIMCO Greensboro, Lake City and Macon facilities, the
Company has further substantially completed an assessment of its non-IT systems
which the Company has identified as containing embedded chip systems for Year
2000 issues. At this point in its assessment, the Company is not currently aware
of any Year 2000 problems relating to these systems which would have a material
effect on the Company's business, results of operations, or financial condition,
without taking into account the Company's efforts to avoid such problems.

         Additionally, the Company is reviewing the efforts of its vendors and
customers to become Year 2000 compliant. Letters and questionnaires have been or
are in the process of being sent to all critical entities with which the Company
does business to assess their Year 2000 readiness. To date, the Company has
received responses from approximately 40% of such third parties, and
approximately 60% of the companies that have responded have provided assurances
to the Company that they have already addressed, or that they will address on a
timely basis, all of their known significant Year 2000 issues. The Company
anticipates that these activities will be on-going for all of 1999 and will
include follow-up telephone interviews, correspondence and on-site meetings as
considered necessary in the circumstances. Although this review is continuing,
the Company is not currently aware of any vendor or customer circumstances that
may have a material adverse impact on the Company. The Company will seek
alternative suppliers if circumstances warrant. The Company can provide no
assurance that Year 2000 compliance plans of its vendors and customers will be
completed on a timely manner.

         In that regard, the Company believes that issues relating to the Year
2000 compliance of aircraft spare parts in its inventory, if any, will
ultimately be the responsibility of the manufacturers of such parts, although
there can be no assurance. Further, it is unclear whether the Company's product
liability insurance would ultimately cover a claim based upon a Year 2000
problem in a part sold by the Company.

         The Company's IT systems and other business resources rely on IT
systems and non-IT systems provided by service providers and therefore may be
vulnerable to those service providers' failure to remediate their own Year 2000
issues. Such service providers include those for the Company's network and
e-mail services and landlords for the Company's currently occupied leased office
spaces. The Company has contacted these principal service providers and has been
notified that the IT and non-IT systems which they provide to the Company are
Year 2000 compliant.

                                        5

         COSTS

         The Company believes that the cost of the new MIS system (i) for its
distribution services business will be approximately $13.5 million, of which
approximately $4.8 million has been expended to date and approximately $8.7
million of which it believes will be expended during 1999 and (ii) for its
manufacturing business will be approximately $2.1 million of which approximately
$947,000 has been spent to date and approximately $1.15 million will be expended
during 1999. At present, the Company is in the early stages of assessing the
Year 2000 compliance of its TIMCO Greensboro, Lake City and Macon facilities.
Until such assessment is substantially complete, the Company does not believe it
will be in a position to estimate the Year 2000 compliance costs for its MR&O
business. The costs of the Company's new MIS systems are being funded from the
Company's existing lines of credit. The $4.8 million and $976,000, respectively,
spent to date has related substantially to the cost of the new MIS systems and
not to bringing the Company's existing MIS systems into Year 2000 compliance.
Such cost estimates include both hardware and software costs, as well as the
anticipated costs of the use of consultant services, but do not include Company
internal costs associated with such efforts, which are not separately tracked
for Year 2000 compliance efforts. Such internal costs principally consist of the
payroll costs for Company employees working on such compliance efforts.

         If the Company determines that due to delays in the implementation of
its new MIS system for its distribution services business, it is in the
Company's best interest to update its existing MIS system for such business to
make it Year 2000 compliant, so that such system remains available for use in
the Company's business until the new MIS system for business becomes
operational, the cost of such update is expected to be approximately $3.5
million. Such cost, if incurred, would be in addition to the costs associated
with the development and implementation of the new MIS system for its
distribution services business as described above, and would not be recoverable
in connection with the development and implementation of the new MIS system for
such business.

         RISKS RELATING TO THE COMPANY'S FAILURE TO BECOME YEAR 2000 COMPLIANT

         To the extent that the Company's assessment is finalized without
identifying any additional material non-compliant IT systems operated by the
Company or by third parties, the most reasonably likely worst case Year 2000
scenario is that the Company will have to bring its existing MIS systems into
Year 2000 compliance; provided, however, that while the Company believes based
upon its assessments that its existing systems can be made Year 2000 compliant
prior to December 31, 1999, there can be no assurance of this fact. The Company
believes that it will be able to either bring its new MIS systems substantially
into operation or bring its existing systems into Year 2000 compliance by the
end of 1999, although there can be no assurance.

         The Company's failure to bring either its new MIS systems into
operation or bring its existing MIS systems into Year 2000 compliance by the end
of 1999 would likely have a material adverse effect on the Company, in that it
would make it very difficult for the Company to operate its business in the
ordinary course and would likely cause the Company to lose revenues, have
increased operating

                                        6


<PAGE>



costs and have business interruptions of a material nature (which would likely
not be covered by the Company's existing business interruption insurance) until
such systems were in place. In addition, there can be no assurance that the Year
2000 issues of other entities will not have a material adverse impact on the
Company's systems or results of operations.

         CONTINGENCY PLANS

         As discussed above, the Company is engaged in an ongoing Year 2000
assessment in order to determine the operational problems and costs (including
loss of revenues) that would be reasonably likely to result from the failure by
the Company and certain third parties to complete efforts necessary to achieve
Year 2000 compliance on a timely basis. The Company is currently continuing to
develop its new MIS systems for its distribution services business, and hopes to
be in a position by March 1999 to determine whether such system will be far
enough along in its development so that it can be made operational prior to the
end of 1999. Alternatively, unless by the end of April 1999 the Company has
determined that it is reasonably likely that it will be in a position to bring
its new MIS system for its distribution services business into operation prior
to the end of the year, the Company will likely opt to expend the costs
associated with bringing the Company's existing MIS system for its distribution
services business into Year 2000 compliance.

         The Company is currently considering what its contingency plans will be
in the event that the Company is not able to bring its existing MIS systems for
its TIMCO Greensboro, Lake City and Macon facilities into Year 2000 compliance
by the end of 1999. The Company currently plans to complete such contingency
plans by the end of March 1999.

FILING OF PAINEWEBBER LAWSUIT

         On January 8, 1999, PaineWebber Incorporated ("PaineWebber") filed in
the Supreme Court of the State of New York a complaint against the Company and
its subsidiary, Whitehall Corporation ("Whitehall") alleging breach of contract
claims and related claims against the Company and Whitehall and a tortious
interference with a contract claim against the Company in connection with the
Company's acquisition of TIMCO in September 1998. These claims primarily arose
based upon a 1997 agreement between Whitehall and PaineWebber relating to
certain investment banking services to be provided to Whitehall by PaineWebber
in connection with a proposed acquisition of TIMCO by Whitehall. PaineWebber is
seeking damages of approximately $1.0 million, plus costs, payment of
approximately $250,000 allegedly due relating to the failure of Whitehall to
honor an alleged right of first refusal in the 1997 agreement, and an unstated
amount of punitive damages.

         The Company believes that its acquisition of TIMCO was not within the
scope of the PaineWebber/Whitehall agreement and that claims brought under this
agreement against the Company and Whitehall are without merit. The Company
intends to vigorously defend these claims. Although no assurance can be given,
the Company believes that the ultimate outcome of this matter will not have a
material adverse effect on the financial condition of the Company.

                   SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

         2.1.       COMMITMENTS.

                    (a) Subject to the terms and conditions hereof, each Lender
         severally agrees to make Series A Loans and Series B Loans to the
         Borrower from time to time during the Commitment Period for the purpose
         of enabling the Borrower to purchase the Properties and to pay Property
         Acquisition Costs, Property Costs and Transaction Expenses, in an
         aggregate principal amount as to each Category of Loans at any one time
         outstanding not to exceed such Lender's Commitment applicable to such
         Category of Loans; PROVIDED that (i) after giving effect to any Loan,
         the aggregate outstanding principal amount of all Loans of a specified
         Category shall not exceed the Total Commitment for such Category, and
         (ii) all borrowings under this SECTION 2.1(A), when aggregated with
         corresponding Holder Fundings, shall be allocated as follows: Series A
         Loans--88%; Series B Loans--9%; and Holder Fundings--3%.

                    (b) The Loans may be Base Rate Loans or Eurodollar Loans
         having an Interest Period of one, two, three or six months, as
         specified in the definition of "Interest Period," subject only to the
         limitations specified in such definition and to the provisions of
         SECTIONS 2.7, 2.9(C) AND 2.11. Any Loan other than a Eurodollar Loan
         shall constitute a Base Rate Loan.

         2.2. NOTES. The Loans made by each Lender shall be evidenced by (i) in
the case of Series A Loans, a promissory note of the Borrower, substantially in
the form of EXHIBIT A (the "Series A Note"), and (ii) in the case of Series B
Loans, a promissory note of the Borrower, substantially in the form of EXHIBIT B
(the "Series B Note" and together with the Series A Notes, the "Notes"), in each
case with appropriate insertions as to payee, date and principal amount, payable
to the order of such Lender and in a principal amount equal to the applicable
Commitment of such Lender. Each Lender is hereby authorized to record the date,
Type and amount of each Loan made by such Lender, each continuation thereof,
each conversion of all or a portion thereof to another Type, and the date and
amount of each payment or prepayment of principal thereof on the schedule
annexed to and constituting a part of any of its Notes, and any such recordation
shall constitute PRIMA FACIE evidence of the accuracy of the information so
recorded, PROVIDED that the failure to make any such recordation or any error in
such recordation shall not affect the Borrower's obligations hereunder or under
such Note. Each Note shall (i) be dated the Initial Closing Date (ii) be stated
to mature on the Maturity Date, and (iii) provide for the payment of interest in
accordance with SECTION 2.8.

         2.3.       PROCEDURE FOR BORROWING; AMOUNTS OF BORROWINGS.

                    (a) The Borrower may borrow under the Commitments during the
         Commitment Period on any Business Day that a Funding may be requested
         pursuant to the terms of SECTION 5.2 of the Participation Agreement,
         PROVIDED that the Borrower shall give the Administrative Agent
         irrevocable notice (which must be received by the Administrative Agent
         (i) prior to 11:00 A.M., Charlotte, North Carolina time, three Business
         Days prior to the requested Borrowing Date if all or any part of the
         requested Loans are to be Eurodollar Loans, or (ii)

                                        2


<PAGE>



         prior to 11:00 A.M., Charlotte, North Carolina time one (1) Business
         Day prior to the requested Borrowing Date with respect to any Loans
         that are to be Base Rate Loans) specifying (A) the amount to be
         borrowed (which on any date shall not be in excess of the then
         Available Commitments), (B) the requested Borrowing Date, (C) whether
         the borrowing is to be of Eurodollar Loans, Base Rate Loans or a
         combination thereof, and (D) if the borrowing is to be a combination of
         Eurodollar Loans and Base Rate Loans, the respective amounts of each
         Type of Loan; PROVIDED, HOWEVER, that prior to the Completion Date for
         any specified Property (1) there shall be only one Interest Period in
         effect at any specified time, which Interest Period shall apply to all
         amounts then outstanding hereunder with respect to such Property that
         are bearing interest based on the Eurodollar Rate and which Interest
         Period shall each be one month in length (subject to the adjustments
         set forth in the definition of "Interest Period"), (2) the first
         Interest Period shall commence on the date that the first Eurodollar
         Loan hereunder is extended, (3) each succeeding Interest Period shall
         begin on the last day of the preceding Interest Period, and (4) any
         amounts borrowed or converted hereunder which are to bear interest
         based on the Eurodollar Rate may only be borrowed or converted on the
         first day of a permitted Interest Period. Pursuant to the terms of the
         Participation Agreement, the Borrower shall be deemed to have delivered
         such notice upon the delivery of a notice by the Construction Agent or
         the Lessee containing such required information. Upon receipt of any
         such notice from the Borrower, the Administrative Agent shall promptly
         notify each Lender thereof. Subject to the terms and conditions hereof
         (including specifically without limitation SECTION 4.2), each Lender
         will make the amount of its pro rata share of each borrowing of each
         Category available to the Administrative Agent for the account of the
         Borrower at the office of the Administrative Agent specified in SECTION
         9.2 prior to 2:00 P.M., Charlotte, North Carolina time, on the
         Borrowing Date requested by the Borrower in funds immediately available
         to the Administrative Agent. Such borrowing will then be made available
         to the Borrower by the Administrative Agent crediting an account
         designated, subject to SECTION 11.1 of the Participation Agreement, by
         the Borrower on the books of such office with the aggregate of the
         amounts made available to the Administrative Agent by the Lenders and
         in like funds as received by the Administrative Agent. No amount of any
         Loan which is repaid or prepaid may be reborrowed hereunder.

                    (b) The Borrower shall deliver an Allocation Notice to the
         Administrative Agent at least five (5) Business Days before any
         Scheduled Interest Payment Date. On each date which is three (3)
         Business Days prior to any Scheduled Interest Payment Date that occurs
         during the Commitment Period, the Borrower shall be deemed to have
         requested a Eurodollar Loan pursuant to SECTION 2.3(A) in an amount
         equal to the aggregate amount of Allocated Interest due and payable on
         such date with respect to the Construction Period Properties. Upon
         receipt of any Allocation Notice from the Borrower with respect to such
         Allocated Interest, the Administrative Agent shall promptly notify each
         Lender thereof. The Borrowing Date with respect to any such borrowing
         shall be the relevant Scheduled Interest Payment Date (PROVIDED that
         the making of the Loans pursuant to such borrowing shall be subject to
         satisfaction of the applicable conditions precedent set forth in
         SECTION 4.2) and the proceeds of such borrowing shall be applied to pay
         such Allocated Interest. On each such Borrowing Date, the Loan Property
         Cost and Construction Loan Property Cost shall be increased by an

                                        3


<PAGE>



         amount equal to the Allocated Interest paid on such date with respect
         to such Property with the proceeds of such borrowing.

                    (c) The aggregate amount of any borrowing constituting a
         Eurodollar Loan and any conversion thereof shall be in an amount of at
         least $1,000,000.

         2.4. UNUSED FEES. Promptly after receipt from the Lessee of payment of
any Unused Fees payable pursuant to the Participation Agreement, the
Administrative Agent shall distribute such payment to the Lenders pro rata
according to their respective Commitment Percentages.

         2.5.       TERMINATION OR REDUCTION OF COMMITMENTS.

                    (a) The Borrower shall have the right, upon not less than
         five (5) Business Days' written notice to the Administrative Agent, to
         terminate the Commitments or, from time to time (but not more than
         twice), to permanently reduce the amount of the Commitments, such
         reductions to be effected pro rata among Categories of Loans and in
         conjunction with simultaneous pro rata reductions of the Holder
         Commitments, PROVIDED, that (i) after giving effect to such reduction,
         the aggregate outstanding principal amount of the Loans of any Category
         shall not exceed the aggregate Commitments of such Category and the
         aggregate outstanding amount of Holder Fundings shall not exceed the
         aggregate Holder Commitments, (ii) such notice shall be accompanied by
         a certificate of the Construction Agent stating that the amount equal
         to 97% of aggregate Budgeted Total Loan Property Cost as of the date of
         such reduction does not exceed the aggregate amount of Available
         Commitments as of such date after giving effect to such reduction and
         (iii) unless a Lease Default or Lease Event of Default has occurred and
         is continuing, the Lessee or the Construction Agent shall have
         consented to such reduction or termination. Any such reduction of
         Commitments and Holder Commitments shall be in an aggregate amount
         equal to the lesser of (A) $1,000,000 or any integral multiple thereof
         or (B) the remaining Available Commitments of each Category and the
         remaining Available Holder Commitments, and shall reduce permanently
         the Commitments of each Category and the Holder Commitments then in
         effect.

                    (b) On any date on which the Commitments of any Category
         shall automatically be reduced to zero pursuant to SECTION 6, the
         Borrower shall prepay all outstanding Loans, together with accrued
         unpaid interest thereon and all other amounts owing hereunder or under
         any other Credit Document.

         2.6.       PREPAYMENTS AND PAYMENTS.

                    (a) The Borrower may at any time and from time to time
         prepay the Loans, in whole or in part, without premium or penalty, upon
         at least two (2) Business Days' irrevocable notice to the
         Administrative Agent, specifying the date and amount of prepayment and
         whether the prepayment is of Eurodollar Loans, Base Rate Loans or a
         combination thereof, and, if a combination thereof, the amount
         allocable to each; provided that all prepayments of Loans shall be
         applied pro rata between Series A Loans (aggregated as a single amount)
         and Series B Loans (aggregated as a single amount). Upon receipt of any

                                        4


<PAGE>



         such notice the Administrative Agent shall promptly notify each Lender
         thereof. If any such notice is given, the amount specified in such
         notice shall be due and payable on the date specified therein. Amounts
         prepaid may not be reborrowed.

                    (b) If on any date the Administrative Agent or the Lessor
         shall receive any payment in respect of (i) any Casualty or
         Condemnation pursuant to SECTION 15.1(A) or 15.1(G) of the Lease
         (excluding any payments in respect thereof which are payable to Lessee
         in accordance with the Lease), or (ii) the Termination Value of any
         Property in connection with the delivery of a Termination Notice
         pursuant to ARTICLE XVI of the Lease, or (iii) the Termination Value of
         any Property in connection with the exercise of the option to purchase
         any Property under SECTION 17.11 of the Lease, or (iv) the Termination
         Value of any Property in connection with the exercise of a Purchase
         Option under SECTION 20.1 of the Lease or the exercise of the option of
         the Lessee to transfer the Properties to a third party pursuant to
         SECTION 20.1 of the Lease, or (v) any payment required to be made or
         elected to be made by the Construction Agent to the Lessor pursuant to
         the terms of the Agency Agreement, then in each case, the Borrower
         shall be required to prepay the principal balance of the Loans on such
         date (such prepayment to be applied pro rata as between Series A Loans
         (aggregated as a single amount) and Series B Loans (aggregated as a
         single amount)) in an amount equal to ninety-seven percent (97%) of
         such payment and shall apply the remaining three percent (3%) of such
         payment pro rata to the principal amount of outstanding Holder
         Fundings.

                    (c) Each prepayment of the Loans pursuant to SECTION 2.6(B)
         shall be allocated to reduce the Loan Property Cost of the affected
         Property. Each prepayment of the Loans pursuant to SECTION 2.6(A) shall
         be allocated to reduce the respective Loan Property Costs of all
         Properties pro rata according to the Loan Property Costs of such
         Properties immediately before giving effect to such prepayment. Any
         amounts applied to reduce the Loan Property Cost of any Construction
         Period Property pursuant to this paragraph (c) shall also be applied to
         reduce the Construction Loan Property Cost of such Property until such
         Construction Loan Property Cost has been reduced to zero. Each
         prepayment of the Loans pursuant to SECTION 2.6(A) or 2.6(B) shall be
         accompanied by a simultaneous prepayment of accrued interest on such
         Loan and the simultaneous payment of any amounts payable under SECTION
         2.12 hereof in connection with the prepayment of such Loan.

                    (d) The outstanding principal amount of the Loans shall be
         due and payable in full to the Agent for the benefit of each Lender on
         the Maturity Date, or earlier as specified herein or in any other
         Operative Agreement.

         2.7.       CONVERSION AND CONTINUATION OPTIONS.

                    (a) Subject to the restrictions set forth in SECTIONS 2.3, 
         2.9(C) AND 2.11 the Borrower may:

                             (i) upon delivery of written notice to the Agent on
                    or before 11:00 A.M. one (1) Business Day prior to the date
                    of such conversion, convert all or a part of

                                        5


<PAGE>



                    Eurodollar Rate Loans to Base Rate Loans on the last day of
                    the Interest Period for such Eurodollar Rate Loans; and

                             (ii) upon delivery of written notice to the Agent
                    on or before 11:00 A.M. three (3) Business Days' prior to
                    the date of such election or conversion:

                                     (A) elect a subsequent Interest Period for
                             all or a portion of Eurodollar Rate Loans to begin
                             on the last day of the then current Interest Period
                             for such Eurodollar Rate Loans; and

                                     (B) convert Base Rate Loans to Eurodollar
                             Rate Loans on any Business Day.

         All or any part of outstanding Eurodollar Loans or Base Rate Loans may
         be converted as provided herein, PROVIDED that (i) no Base Rate Loan
         may be converted into a Eurodollar Loan when any Event of Default has
         occurred and is continuing, (ii) no Base Rate Loan may be converted
         into a Eurodollar Loan which matures after the Maturity Date, (iii)
         during the Commitment Period such conversion may only occur on the
         first day of an Interest Period permitted pursuant to the terms of
         SECTION 2.3 hereof and (iv) such notice of conversion shall contain an
         election by the Borrower of an Interest Period for such Eurodollar Loan
         to be created by such conversion and such Interest Period shall be in
         accordance with the terms of the definition of the term "Interest
         Period" as set forth in Appendix A to the Participation Agreement and
         PROVIDED, FURTHER, that with respect to each conversion or continuation
         of any Eurodollar Rate Loan, if the Borrower shall fail to give any
         required notice or if such continuation is not permitted pursuant to
         the preceding provision, such Loan shall be automatically converted to
         a Base Rate Loan on the last day of such then expiring Interest Period.

         2.8.       INTEREST RATES AND PAYMENT DATES.

                    (a) Each Eurodollar Loan shall bear interest for each day
         during each Interest Period with respect thereto at a rate per annum
         equal to the Eurodollar Rate for such day for such Loan.

                    (b) Each Base Rate Loan shall bear interest at a rate per
         annum equal to the Base Rate.

                    (c) If all or a portion of (i) the principal amount of any
         Loan, (ii) any interest payable on any Loan or (iii) any other amount
         payable hereunder shall not be paid when due (subject to applicable
         grace periods) (whether at the stated maturity, by acceleration or
         otherwise), such overdue amount shall bear interest at a rate per annum
         which is the lesser of (x) the interest rate applicable to such Loan
         (or in the case of clause (iii) above, the Base Rate) plus 2% and (y)
         the highest interest rate permitted by applicable law, in each case
         from the date of such non-payment until such amount is paid in full
         (whether after or before judgment).

                                        6


<PAGE>



                    (d) Interest shall be payable in arrears on each Scheduled
         Interest Payment Date, PROVIDED that (i) interest accruing pursuant to
         paragraph (c) of this SECTION 2.8 shall be payable from time to time on
         demand and (ii) each prepayment of any Loan shall be accompanied by
         accrued interest to the date of such prepayment on the amount prepaid.

         2.9.       COMPUTATION OF INTEREST.

                    (a) Interest shall be calculated on the basis established in
         SECTION 14.16 of the Participation Agreement, with respect to length of
         a "year" and number of days for which interest is accrued. The
         Administrative Agent shall as soon as practicable notify the Borrower
         and the Lenders of each determination of a Eurodollar Rate. Any change
         in the interest rate on a Loan resulting from a change in the Base
         Rate, or the Reserve Percentage, shall become effective as of the day
         on which such change in the Base Rate or Reserve Percentage becomes
         effective. The Administrative Agent shall as practicable notify the
         Borrower and the Lenders of the effective date and the amount of each
         such change in interest rate.

                    (b) Each determination of an interest rate by the
         Administrative Agent pursuant to any provision of this Agreement shall
         be conclusive and binding on the Borrower and the Lenders in the
         absence of manifest error.

                    (c) If the Eurodollar Rate cannot be determined by the
         Administrative Agent in the manner specified in the definition of the
         term "Eurodollar Rate" referenced in Appendix A to the Participation
         Agreement, the Administrative Agent shall give telefacsimile or
         telephonic notice thereof to the Borrower and the Lenders as soon as
         practicable thereafter. Until such time as the Eurodollar Rate can be
         determined by the Administrative Agent in the manner specified in such
         definition of such term, no further Eurodollar Loans shall be made or
         continued as such at the end of the then current Interest Period and
         all Loans shall continue as Base Rate Loans.

         2.10.      PRO RATA TREATMENT AND PAYMENTS.

                    (a) Each borrowing by the Borrower from the Lenders
         hereunder and any reduction of the Commitments of any Category of the
         Lenders shall be made pro rata according to the respective Commitment
         Percentages of such Category of the Lenders. Each payment (including
         each prepayment) by the Borrower on account of principal of and
         interest on the Series A Loans or the Series B Loans, as the case may
         be, shall be made pro rata according to the respective outstanding
         principal amounts on the Loans of each such Category then held by each
         Lender. All payments (including prepayments) to be made by the Borrower
         hereunder and under the Notes, whether on account of principal,
         interest or otherwise, shall be made without setoff, counterclaim or
         other defense and shall be made prior to 12:00 Noon, Charlotte, North
         Carolina time, on the due date thereof to the Administrative Agent, for
         the account of the Lenders, at the Administrative Agent's office
         specified in SECTION 9.2, in Dollars and in immediately available
         funds. The Administrative Agent shall distribute such payments to the
         Lenders promptly upon receipt in like funds as received. If any payment
         hereunder becomes due and payable on a day other than a Business Day,
         such

                                        7


<PAGE>



         payment shall be extended to the next succeeding Business Day;
         PROVIDED, HOWEVER, if such payment includes an amount of interest
         calculated with reference to the Eurodollar Rate and the result of such
         extension would be to extend such payment into another calendar month,
         then such payment shall be made on the immediately preceding Business
         Day. In the case of any extension of any payment of principal pursuant
         to the preceding two sentences, interest thereon shall be payable at
         the then applicable rate during such extension.

                    (b) Unless the Administrative Agent shall have been notified
         in writing by any Lender prior to a borrowing that such Lender will not
         make its share of such borrowing available to the Administrative Agent,
         the Administrative Agent may assume that such Lender is making such
         amount available to the Administrative Agent, and the Administrative
         Agent may, in reliance upon such assumption, make available to the
         Borrower a corresponding amount. If such amount is not made available
         to the Administrative Agent by the required time on the Borrowing Date
         therefor, such Lender shall pay to the Administrative Agent, on demand,
         such amount with interest thereon at a rate equal to the daily average
         Federal Funds Rate for the period until such Lender makes such amount
         immediately available to the Administrative Agent. A certificate of the
         Administrative Agent submitted to any Lender with respect to any
         amounts owing under this SECTION 2.10(B) shall be conclusive in the
         absence of manifest error. If such Lender's share of such borrowing is
         not made available to the Administrative Agent by such Lender within
         three Business Days of such Borrowing Date, the Administrative Agent
         shall also be entitled to recover such amount with interest thereon at
         the rate as set forth above on demand from the Borrower.

         2.11.      CHANGE IN CIRCUMSTANCES.

                    (a) INCREASED COST. If, after the date hereof, the adoption
         of any applicable law, rule, or regulation, or any change in any
         applicable law, rule, or regulation, or any change in the
         interpretation or administration thereof by any governmental authority,
         central bank, or comparable agency charged with the interpretation or
         administration thereof, or compliance by any Lender (or its Applicable
         Funding Office) with any request or directive (whether or not having
         the force of law) of any such governmental authority, central bank, or
         comparable agency:

                             (i) shall subject such Lender (or its Applicable
                    Funding Office) to any tax, duty or other charge with
                    respect to any Eurodollar Loans, its Notes, or its
                    obligation to make Eurodollar Loans, or change the basis of
                    taxation of any amounts payable to such Lender (or its
                    Applicable Funding Office) under this Agreement or its Notes
                    in respect of any Eurodollar Loans (other than taxes imposed
                    on the overall net income of such Lender by the jurisdiction
                    in which such Lender has its principal office or such
                    Applicable Funding Office);

                             (ii) shall impose, modify, or deem applicable any
                    reserve, special deposit, assessment, or similar requirement
                    (other than the Reserve Requirement utilized in the
                    determination of the Eurodollar Rate) relating to any
                    extensions of credit or other assets of, or any deposits
                    with or other liabilities or commitments of, such

                                        8


<PAGE>



                    Lender (or its Applicable Funding Office), including the
                    Commitment of such Lender hereunder; or

                             (iii) shall impose on such Lender (or its
                    Applicable Funding Office) or on the London interbank market
                    any other condition affecting this Agreement, its Notes, any
                    other Operative Agreement or any of such extensions of
                    credit or liabilities and commitments;

         and the result of any of the foregoing is to increase the cost to such
         Lender (or its Applicable Lending Office) of making, converting into,
         continuing, or maintaining any Eurodollar Loans or to reduce any sum
         received or receivable by such Lender (or its Applicable Funding
         Office) under this Agreement or its Notes with respect to any
         Eurodollar Loans, then the Borrower shall pay to such Lender on demand
         such amount or amounts as will compensate such Lender for such
         increased cost or reduction. If any Lender requests compensation by the
         Borrower under this SECTION 2.11(A), the Borrower may, by notice to
         such Lender (with a copy to the Administrative Agent), suspend the
         obligation of such Lender to make or continue loans of the Type with
         respect to which such compensation is requested, or to convert Loans of
         any other Type into Loans of such Type, until the event or condition
         giving rise to such request ceases to be in effect (in which case the
         provisions of SECTION 2.11(F) shall be applicable); provided that such
         suspension shall not affect the right of such Lender to receive the
         compensation so requested.

                    (b) REDUCED RETURN. If, after the date hereof, any Lender
         shall have determined that the adoption of any applicable law, rule or
         regulation regarding capital adequacy or any change therein or in the
         interpretation or administration thereof by any governmental authority,
         central bank or comparable agency charged with the interpretation or
         administration thereof, or any request or directive regarding capital
         adequacy (whether or not having the force of law) of any such
         governmental authority, central bank or comparable agency, has or would
         have the effect of reducing the rate of return on the capital of such
         Lender or any corporation controlling such Lender as a consequence of
         such Lender's obligations hereunder to a level below that which such
         Lender or such corporation could have achieved but for such adoption,
         change, request, or directive (taking into consideration its policies
         with respect to capital adequacy), then from time to time upon demand
         by such Lender the Borrower shall pay to such Lender such additional
         amount or amounts as will compensate such Lender for such reduction.

                    (c) NOTICE; DESIGNATION OF APPLICABLE FUNDING OFFICE. Each
         Lender shall promptly notify the Borrower and the Administrative Agent
         of any event of which it has knowledge, occurring after the date
         hereof, which will entitle such Lender to compensation pursuant to this
         SECTION 2.11 and will designate a different Applicable Funding Office
         if such designation will avoid the need for, or materially reduce the
         amount of, such compensation and will not, in the judgment of such
         Lender, be otherwise disadvantageous to it. Any Lender claiming
         compensation under this SECTION 2.11 shall furnish to the Borrower and
         the Administrative Agent a statement setting forth the additional
         amount or amounts to be paid

                                        9


<PAGE>



         to it hereunder which shall be conclusive in the absence of manifest
         error. In determining such amount, such Lender may use any reasonable
         averaging and attribution methods.

                    (d) LIMITATION ON TYPES OF LOANS. If on or prior to the
         first day of any Interest Period for any Eurodollar Loan:

                             (i) the Administrative Agent determines (which
                    determination shall be conclusive) that by reason of
                    circumstances affecting the relevant market, adequate and
                    reasonable means do not exist for ascertaining the
                    Eurodollar Rate for such Interest Period; or

                             (ii) the Majority Lenders determine (which
                    determination shall be conclusive) and notify the
                    Administrative Agent that the Eurodollar Rate will not
                    adequately and fairly reflect the cost to the Lenders of
                    funding Eurodollar Loans for such Interest Period;

         then the Administrative Agent shall give the Borrower prompt notice
         thereof specifying the relevant Type of Loans and the relevant amounts
         or periods, and so long as such condition remains in effect, the
         Lenders shall be under no obligation to make additional Loans of such
         Type, continue Loans of such Type, or to convert Loans of any other
         Type into Loans of such Type and the Borrower shall, on the last day(s)
         of the then current Interest Period(s) for the outstanding Loans of the
         affected Type, either prepay such Loans, or convert such Loans into
         another Type of Loan in accordance with the terms of this Agreement.

                    (e) ILLEGALITY. Notwithstanding any other provision of this
         Agreement, in the event that it becomes unlawful for any Lender or its
         Applicable Funding Office to make, maintain, or fund Eurodollar Loans
         hereunder, then such Lender shall promptly notify the Borrower thereof
         and such Lender's obligation to make or continue Eurodollar Loans and
         to convert other Types of Loans into Eurodollar Loans shall be
         suspended until such time as such Lender may again make, maintain, and
         fund Eurodollar Loans (in which case the provisions of SECTION 2.11(F)
         shall be applicable).

                    (f) TREATMENT OF AFFECTED LOANS. If the obligation of any
         Lender to make a Eurodollar Loan or to continue, or to convert Loans of
         any other Type into, Loans of a particular Type shall be suspended
         pursuant to SECTION 2.11(A), (B) or (E) (Loans of such Type being
         herein called "Affected Loans" and such Type being herein called the
         "Affected Type"), such Lender's Affected Loans shall be automatically
         converted into Base Rate Loans on the last day(s) of the then current
         Interest Period(s) for Affected Loans (or, in the case of a conversion
         required by SECTION 2.11(E), on such earlier date as such Lender may
         specify to the Borrower with a copy to the Administrative Agent) and,
         unless and until such Lender gives notice as provided below that the
         circumstances specified in SECTION 2.11(A), (B) or (E) that gave rise
         to such conversion no longer exist:

                                       10


<PAGE>



                             (i) to the extent that such Lender's Affected Loans
                    have been so converted, all payments and prepayments of
                    principal that would otherwise be applied to such Lender's
                    Affected Loans shall be applied instead to its Base Rate
                    Loans; and

                             (ii) all Loans that would otherwise be made or
                    continued by such Lender as Loans of the Affected Type shall
                    be made or continued instead as Base Rate Loans, and all
                    Loans of such Lender that would otherwise be converted into
                    Loans of the Affected Type shall be converted instead into
                    (or shall remain as) Base Rate Loans.

         If such Lender gives notice to the Borrower (with a copy to the
         Administrative Agent) that the circumstances specified in SECTION
         2.11(A), (B) or (E) that gave rise to the conversion of such Lender's
         Affected Loans pursuant to this SECTION 2.11(F) no longer exist (which
         such Lender agrees to do promptly upon such circumstances ceasing to
         exist) at a time when Loans of the Affected Type made by other Lenders
         are outstanding, such Lender's Base Rate Loans shall be automatically
         converted, on the first day(s) of the next succeeding Interest
         Period(s) for such outstanding Loans of the Affected Type, to the
         extent necessary so that, after giving effect thereto, all Loans held
         by the Lenders holding Loans of the Affected Type and by such Lender
         are held pro rata (as to principal amounts, Types, and Interest
         Periods) in accordance with their respective Commitments.

         2.12. COMPENSATION. Upon the request of any Lender, the Borrower shall
pay to such Lender such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost, or
expense (including loss of anticipated profits) incurred by it as a result of:

                    (a) any payment, prepayment, or conversion of a Eurodollar
         Loan for any reason (including, without limitation, the acceleration of
         the Loans pursuant to SECTION 6) on a date other than the last day of
         the Interest Period for such Loan; or

                    (b) any failure by the Borrower for any reason (including,
         without limitation, the failure of any condition precedent specified in
         SECTION 4 hereof or SECTION 5 of the Participation Agreement to be
         satisfied) to borrow, convert, continue, or prepay a Eurodollar Loan on
         the date for such borrowing, conversion, continuation, or prepayment
         specified in the relevant notice of borrowing, prepayment,
         continuation, or conversion under this Agreement.

         2.13.      TAXES.

                    (a) Any and all payments by the Borrower to or for the
         account of any Lender or the Administrative Agent hereunder or under
         any other Operative Agreement shall be made free and clear of and
         without deduction for any and all present or future taxes, duties,
         levies, imposts, deductions, charges or withholdings, and all
         liabilities with respect thereto, EXCLUDING, in the case of each Lender
         and the Administrative Agent, taxes imposed on its income, capital
         gains, net worth, capital or equity and franchise taxes imposed on it,
         by the
                                       11


<PAGE>



         jurisdiction under the laws of which such Lender (or its Applicable
         Funding Office or any other office) or the Administrative Agent (as the
         case may be) is organized or any political subdivision thereof (all
         such non-excluded taxes, duties, levies, imposts, deductions, charges,
         withholdings, and liabilities being hereinafter referred to as
         "Non-Excluded Taxes"). If the Borrower shall be required by law to
         deduct any Non-Excluded Taxes from or in respect of any sum payable
         under this Agreement or any other Operative Agreement to any Lender or
         the Administrative Agent, (i) the sum payable shall be increased as
         necessary so that after making all required deductions (including
         deductions applicable to additional sums payable under this SECTION
         2.13) such Lender or the Administrative Agent receives an amount equal
         to the sum it would have received had no such deductions been made,
         (ii) the Borrower shall make such deductions, (iii) the Borrower shall
         pay the full amount deducted to the relevant taxation authority or
         other authority in accordance with applicable law, and (iv) the
         Borrower shall furnish to the Administrative Agent, at its address
         referred to in SECTION 9.2, the original or a certified copy of a
         receipt evidencing payment thereof.

                    (b) In addition, the Borrower agrees to pay or cause to be
         paid any and all present or future stamp or documentary taxes and any
         other excise or property taxes or charges or similar levies which arise
         from any payment made under this Agreement or any other Operative
         Agreement or from the execution or delivery of, or otherwise with
         respect to, this Agreement or any other Operative Agreement
         (hereinafter referred to as "Other Taxes").

                    (c) The Borrower agrees to indemnify each Lender and the
         Administrative Agent for the full amount of Non-Excluded Taxes and
         Other Taxes (including, without limitation, any Non-Excluded Taxes or
         Other Taxes imposed or asserted by any jurisdiction on amounts payable
         under this SECTION 2.13) paid by such Lender or the Administrative
         Agent (as the case may be) and any liability (including penalties,
         interest, and expenses) arising therefrom or with respect thereto.

                    (d) Each Lender organized under the laws of a jurisdiction
         outside the United States, on or prior to the date of its execution and
         delivery of this Agreement in the case of each Lender listed on the
         signature pages hereof and on or prior to the date on which it becomes
         a Lender in the case of each other Lender, and from time to time
         thereafter if requested in writing by the Borrower or the
         Administrative Agent (but only so long as such Lender remains lawfully
         able to do so), shall provide the Borrower and the Administrative Agent
         with (i) Internal Revenue Service Form 1001 or 4224, as appropriate, or
         any successor form prescribed by the Internal Revenue Service,
         certifying that such Lender is entitled to benefits under an income tax
         treaty to which the United States is a party which reduces the rate of
         withholding tax on payments of interest or certifying that the income
         receivable pursuant to this Agreement is effectively connected with the
         conduct of a trade or business in the United States, (ii) Internal
         Revenue Service Form W-8 or W-9, as appropriate, or any successor form
         prescribed by the Internal Revenue Service, and (iii) any other form or
         certificate required by any taxing authority (including any certificate
         required by Sections 871(h) and 881(c) of the Internal Revenue Code),
         certifying that such Lender is entitled to


                                       12


<PAGE>



         an exemption from or a reduced rate of tax on payments pursuant to this
         Agreement or any of the other Operative Agreements.

                    (e) For any period with respect to which a Lender has failed
         to provide the Borrower and the Administrative Agent with the
         appropriate form pursuant to SECTION 2.13(D) (unless such failure is
         due to a change in treaty, law, or regulation occurring subsequent to
         the date on which a form originally was required to be provided), such
         Lender shall not be entitled to indemnification under SECTION 2.13(A)
         or (B) with respect to Non-Excluded Taxes to the extent that the
         provision of such form would have prevented any such Non-Excluded
         Taxes; PROVIDED, however, that should a Lender, which is otherwise
         exempt from or subject to a reduced rate of withholding tax, become
         subject to Non-Excluded Taxes because of its failure to deliver a form
         required hereunder, the Borrower shall take such steps as such Lender
         (at such Lender's expense) shall reasonably request to assist such
         Lender to recover such Non-Excluded Taxes.

                    (f) If the Borrower is required to pay additional amounts to
         or for the account of any Lender pursuant to this SECTION 2.13, then
         such Lender will agree to use reasonable efforts to change the
         jurisdiction of its Applicable Funding Office so as to eliminate or
         reduce any such additional payment which may thereafter accrue if such
         change, in the judgment of such Lender, is not otherwise
         disadvantageous to such Lender.

                    (g) Within thirty (30) days after the date of any payment of
         Non-Excluded Taxes, the Borrower shall furnish to the Administrative
         Agent the original or a certified copy of a receipt evidencing such
         payment.

                    (h) Without prejudice to the survival of any other agreement
         of the Borrower hereunder, the agreements and obligations of the
         Borrower contained in this SECTION 2.13 shall survive the termination
         of the Commitments and the payment in full of the Notes.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

         To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make the Loans, each of the Trust Company and the Owner Trustee
hereby represents and warrants to the Administrative Agent and each Lender as
follows (PROVIDED that the representations in SECTIONS 3.8, 3.9, 3.10, 3.12 and
3.13 are made solely by the Owner Trustee in its capacity as such):

         3.1. DUE ORGANIZATION, ETC. It is a national banking association duly
organized, validly existing and in good standing under the laws of the United
States and has the power and authority to enter into and perform its obligations
under the Trust Agreement and (assuming due authorization, execution and
delivery of the Trust Agreement by the Holders) has the trust power and
authority to act as the Owner Trustee and to enter into and perform the
obligations under each of the other Operative Agreements to which the Trust
Company or the Owner Trustee, as the case may be, is or will be a party and each
other agreement, instrument and document to be executed and delivered by it on
or before the date this representation is made or deemed made in connection with
or as

                                       13


<PAGE>



contemplated by each such Operative Agreement to which the Trust Company or the
Owner Trustee, as the case may be, is or will be a party.

         3.2. AUTHORIZATION; NO CONFLICT. The execution, delivery and
performance of each Operative Agreement to which it is or will be a party,
either in its individual capacity or (assuming due authorization, execution and
delivery of the Trust Agreement by the Holders) as the Owner Trustee, as the
case may be, has been duly authorized by all necessary action on its part and
neither the execution and delivery thereof, nor the consummation of the
transactions contemplated thereby, nor compliance by it with any of the terms
and provisions thereof (a) requires or will require any approval of its
stockholders or any approval or consent of any trustee or holders of any of its
indebtedness or obligations, (b) violates or will violate any current law,
governmental rule or regulation relating to its banking or trust powers, (c)
violates or will violate or result in any breach of or constitute any default
under, or result in the creation of any Lien upon any of its property under, (i)
its charter or by-laws, or (ii) any indenture, mortgage, chattel mortgage, deed
of trust, conditional sales contract, bank loan or credit agreement or other
agreement or instrument to which it is a party or by which it or its properties
may be bound or affected, which violation, breach, default or Lien under clause
(ii) would materially and adversely affect its ability, in its individual
capacity or as Owner Trustee, to perform its obligations under the Operative
Agreements to which it is a party or (d) requires or will require any
Governmental Action by any Governmental Authority regulating its banking or
trust powers.

         3.3. ENFORCEABILITY, ETC. The Trust Agreement and, assuming the Trust
Agreement is the legal, valid and binding obligation of the Holders, each other
Operative Agreement to which the Trust Company or the Owner Trustee, as the case
may be, is or will be a party have been, or will be, duly executed and delivered
by the Trust Company or the Owner Trustee, as the case may be, and the Trust
Agreement and each such other Operative Agreement to which the Trust Company or
the Owner Trustee, as the case may be, is a party constitutes, or upon execution
and delivery will constitute, a legal, valid and binding obligation enforceable
against the Trust Company or the Owner Trustee, as the case may be, in
accordance with the terms thereof.

         3.4. LITIGATION. There is no action or proceeding pending or, to its
knowledge, threatened to which it is or will be a party, either in its
individual capacity or as the Owner Trustee, before any Governmental Authority
that concerns any Property being purchased or leased or Construction Funding
being funded on the date this representation is made or deemed made or that, if
adversely determined, would materially and adversely affect its ability, in its
individual capacity or as Owner Trustee, to perform its obligations under the
Operative Agreements to which it is a party or would question the validity or
enforceability of any of the Operative Agreements to which it is or will become
a party.

         3.5. LESSOR LIENS. Each Property is free and clear of all Lessor Liens.

         3.6. ASSIGNMENT. It has not assigned or transferred any of its right,
title or interest in or under the Lease, the Agency Agreement or its interest in
any Property, except in accordance with the Operative Agreements.

other Operative Agreement attributable to it has occurred and is continuing.

         3.8. DOCUMENTATION. The Owner Trustee, in its trust capacity, is a
party to no documents, instruments or agreements other than the Operative
Agreements (and any other documents delivered in connection with the Operative
Agreements).

         3.9. USE OF PROCEEDS. The Owner Trustee shall use the proceeds of the
Loans solely in accordance with the terms of the Operative Agreements.

         3.10. SECURITIES ACT. Neither the Owner Trustee nor any Person
authorized by the Owner Trustee to act on its behalf has offered or sold any
interest in the Trust Estate or the Notes, or in any similar security relating
to a Property, or in any security the offering of which for the purposes of the
Securities Act of 1933, as amended, would be deemed to be part of the same
offering as the offering of the aforementioned securities to, or solicited any
offer to acquire any of the same from, any Person other than in the case of the
Notes, the Lenders, and neither the Owner Trustee nor any Person authorized by
the Owner Trustee to act on its behalf will take any action which would subject,
as a direct result of such action alone, the issuance or sale of any interest in
the Trust Estate or the Notes to the provisions of Section 5 of the Securities
Act of 1933, as amended, or require the qualification of any Operative Agreement
under the Trust Indenture Act of 1939, as amended.

         3.11. CHIEF PLACE OF BUSINESS. The Owner Trustee's chief place of
business, chief executive office and office where the documents, accounts and
records relating to the transactions contemplated by this Agreement and each
other Operative Agreement are kept are each located at 79 South Main Street,
Salt Lake City, Utah 84111.

         3.12. FEDERAL RESERVE REGULATIONS. The Owner Trustee is not engaged
principally in, and does not have as one of its important activities, the
business of extending credit for the purpose of purchasing or carrying any
margin stock (within the meaning of Regulation U of the Board), and no part of
the proceeds of the Loans will be used by it to purchase or carry any margin
stock or to extend credit to others for the purpose of purchasing or carrying
any such margin stock or for any purpose that violates, or is inconsistent with,
the provisions of Regulations T, U or X of the Board.

         3.13. INVESTMENT COMPANY ACT. The Owner Trustee is not an "investment
company" or a company controlled by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended.

         4.1. CONDITIONS TO EFFECTIVENESS. The effectiveness of this Agreement
is subject to the satisfaction of all conditions precedent set forth in SECTION

                    (e) ALLOCATION NOTICE. With respect to each Interest Payment
         Loan, the Administrative Agent shall have received an Allocation Notice

in connection with the activities described in SECTION 5.1 (including, without

written request of the Administrative Agent, and at the sole expense of the
Borrower, the Borrower will promptly and duly execute and deliver such further

will create or permit to exist at any time (and each of the Borrower and the
Trust Company will, at its own expense, promptly take such action as may be
necessary duly to discharge, or cause to be discharged), any Lessor Liens
attributable to it on the Properties, PROVIDED that the Borrower and the Trust
Company shall not be required to discharge any Lessor Lien while the same is
being contested in good faith by appropriate proceedings diligently prosecuted

impairment of any of the Liens contemplated by the Security Documents or of the
sale, forfeiture or loss of any Property or title thereto or any interest
therein or the payment of Rent, (b) such proceedings shall not materially
interfere with the construction of Improvements on any Property, and (c) such

rights or interests of the Administrative Agent or the Lenders hereunder or
under the other Operative Agreements and (c) agrees to comply with all of the

         as of which made or deemed made; or

                    (f) There shall have occurred and be continuing:

                              (i) any Lease Event of Default or other "Event of
                    Default" (as defined in the Participation Agreement); or

         order, judgment or decree appointing a custodian, receiver, trustee,
         liquidator or conservator of the Borrower or of the whole or any

         rights, powers and privileges purported to be created thereby
         (including, without limitation, a first priority perfected security
         interest in, and Lien on, all of the Properties), in favor of the
         Administrative Agent on behalf of itself and the Lenders, superior to
         and prior to the rights of all third Persons and subject to no other
         Liens (except Permitted Liens); or

                    (i) The Lease, the Guaranty or any other Operative Agreement
         shall cease to be enforceable against the Lessee, the Construction
         Agent or any Guarantor; or

                    (k) Any default by any party shall have occurred and be
         continuing under any lease or sublease (other than the Lease or any
         sublease by Lessee permitted under SECTION 25.2(B) of the Lease) of any
         portion of any Property;

then, and in any such event, (A) if such event is an Event of Default specified
in paragraph (g) above with respect to the Borrower, the Commitments shall
automatically and immediately terminate and the Loans hereunder (with accrued
interest thereon) and all other amounts owing under this Agreement, the Notes
and any other Credit Documents, shall immediately become due and payable,

                                       19


<PAGE>



and (B) if such event is any other Event of Default, either or both of the
following actions may be taken: (i) with the consent of the Majority Lenders,
the Administrative Agent may, or upon the request of the Majority Lenders, the
Administrative Agent shall, by notice to the Borrower, declare the Commitments
to be terminated forthwith, whereupon the Commitments shall immediately
terminate; and (ii) with the consent of the Majority Lenders, the Administrative
Agent may, or upon the request of the Majority Lenders, the Administrative Agent
shall, by notice to the Borrower, declare the Loans hereunder (with accrued
interest thereon) and all other amounts owing under this Agreement, the Notes
and any other Credit Documents, to be due and payable forthwith, whereupon the
same shall immediately become due and payable (any of the foregoing occurrences
or actions referred to in clause (A) or (B) above, being referred to as an
"Acceleration"). Except as expressly provided above in this SECTION 6,
presentment, demand, protest and all other notices of any kind are hereby
expressly waived.

         Upon the occurrence of any Event of Default and at any time thereafter
so long as any Event of Default shall be continuing, the Administrative Agent
may, and upon the written instructions of the Majority Lenders shall, exercise
any or all of the rights and powers and pursue any or all of the remedies
available to it hereunder and under the other Credit Documents and the Lease and
shall have any and all rights and remedies available under the Uniform
Commercial Code or any other provision of law (all such remedies being
cumulative and in addition to any other remedies that may be available).

         Upon the occurrence of any Event of Default and at any time thereafter
so long as any Event of Default shall be continuing, the Administrative Agent
may, and upon request of the Majority Lenders shall, proceed to protect and
enforce this Agreement, the Notes, the Lease, and the other Operative Agreements
by one or more suits or proceedings in equity, at law or in bankruptcy, whether
for the specific performance of any covenant or agreement contained therein or
in execution or aid of any power granted therein, or for foreclosure hereunder,
or for the appointment of a receiver for any Property, or for the recovery of
judgment for any indebtedness secured thereby, or for the enforcement of any
other remedy available under applicable laws.

         The Borrower shall be liable for any and all accrued and unpaid amounts
due hereunder before, during or after the exercise of any of the foregoing
remedies, including without limitation all reasonable legal fees and other
reasonable costs and expenses incurred by the Administrative Agent or any Lender
by reason of the occurrence of any Event of Default or the exercise of remedies
with respect thereto.

                       SECTION 7. THE ADMINISTRATIVE AGENT

         7.1. APPOINTMENT; POWERS, AND IMMUNITIES. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its agent
under this Agreement and the other Operative Agreements with such powers and
discretion as are specifically delegated to the Administrative Agent by the
terms of this Agreement and the other Operative Agreements, together with such
other powers as are reasonably incidental thereto. The Administrative Agent
(which term

                                       20


<PAGE>



as used in this sentence and in SECTION 7.7 and the first sentence of SECTION
7.6 hereof shall include its Affiliates and its own and its Affiliates'
officers, directors, employees, and agents):

                    (a) shall not have any duties or responsibilities except
         those expressly set forth in this Agreement and shall not be a trustee
         or fiduciary for any Lender;

                    (b) shall not be responsible to the Lenders for any recital,
         statement, representation, or warranty (whether written or oral) made
         in or in connection with any Operative Agreement or any certificate or
         other document referred to or provided for in, or received by any of
         them under, any Operative Agreement, or for the value, validity,
         effectiveness, genuineness, enforceability, or sufficiency of any
         Operative Agreement, or any other document referred to or provided for
         therein or for any failure by any Person to perform any of its
         obligations thereunder;

                    (c) shall not be responsible for or have any duty to
         ascertain, inquire into, or verify the performance or observance of any
         covenants or agreements by any Person or the satisfaction of any
         condition or to inspect the property (including the books and records)
         of any Person;

                    (d) shall not be required to initiate or conduct any
         litigation or collection proceedings under any Operative Agreement; and

                    (e) shall not be responsible for any action taken or omitted
         to be taken by it under or in connection with any Operative Agreement,
         except for its own gross negligence or willful misconduct.

         7.2. DELEGATION OF DUTIES. The Administrative Agent may execute any of
its duties under this Agreement and the other Operative Agreements through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

         7.3. RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent shall
be entitled to rely upon any certification, notice, instrument, writing, or
other communication (including, without limitation, any thereof by telephone or
telefacsimile) believed by it to be genuine and correct and to have been signed,
sent or made by or on behalf of the proper Person or Persons, and upon advice
and statements of legal counsel (including counsel for any other Person),
independent accountants, and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note as the holder
thereof for all purposes hereof unless and until the Administrative Agent
receives and accepts an Assignment and Acceptance executed in accordance with
SECTION 9.8 hereof. As to any matters not expressly provided for by this
Agreement, the Administrative Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Lenders, and such instructions shall be
binding on all of the Lenders; PROVIDED, HOWEVER, that the Administrative Agent
shall not be required to take any action that

                                       21


<PAGE>



exposes the Administrative Agent to personal liability or that is contrary to
any Operative Agreement or applicable law or unless it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by it by reason of taking any such action.

         7.4. NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Administrative Agent has received written notice from a
Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". In the
event that the Administrative Agent receives such a notice, the Administrative
Agent shall give notice thereof to the Lenders. The Administrative Agent shall
take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Majority Lenders; PROVIDED that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interest of the Lenders.

         7.5. NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Borrower, the Lessee, the Guarantors and their Subsidiaries and decision to
enter into this Agreement and that it will, independently and without reliance
upon the Administrative Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own analysis and decisions in taking or not taking action under the Operative
Agreements. Except for notices, reports, and other documents and information
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition, or business of the Borrower, the Lessee or any Guarantor or
any of their Subsidiaries or Affiliates that may come into the possession of the
Administrative Agent or any of its Affiliates.

         7.6. INDEMNIFICATION. The Lenders agree to indemnify the Administrative
Agent (to the extent not reimbursed by the Borrower or Lessee, but without
limiting the obligations of the Borrower or the Lessee to do so) ratably in
accordance with their respective Commitments, for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including attorneys' fees), or disbursements of any kind and nature
whatsoever that may be imposed on, incurred by or asserted against the
Administrative Agent (including by any Lender) in any way relating to or arising
out of any Operative Agreement or the transactions contemplated thereby or any
action taken or omitted by the Administrative Agent under any Operative
Agreement; PROVIDED that no Lender shall be liable for any of the foregoing to
the extent they arise from the gross negligence or willful misconduct of the
Person to be indemnified. Without limitation of the foregoing, each Lender
agrees to reimburse the Administrative Agent promptly upon demand for its
ratable share of any costs or expenses payable by the Borrower or Lessee, to the
extent that the Administrative Agent is not promptly reimbursed for such costs
and expenses by the Borrower or Lessee. The agreements contained in this SECTION
7.7 shall survive payment in full of the Loans and all other amounts payable
under this Agreement.

                                       22


<PAGE>




         7.7. RIGHTS AS LENDER. With respect to its Commitment and the Loans
made by it, NationsBank (and any successor acting as Administrative Agent) in
its capacity as a Lender hereunder shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
acting as the Administrative Agent, and the term "Lender" or "Lenders" shall,
unless the context otherwise indicates, include the Administrative Agent in its
individual capacity. NationsBank (and any successor acting as Administrative
Agent) and its affiliates may (without having to account therefor to any Lender)
accept deposits from, lend money to, make investments in, provide services to,
and generally engage in any kind of lending, trust, or other business with any
of the Borrower, the Lessee, or any Guarantor or any of their Subsidiaries or
Affiliates as if it were not acting as Administrative Agent, and NationsBank
(and any successor acting as Administrative Agent) and its Affiliates may accept
fees and other consideration from any of the Borrower, the Lessee or any
Guarantor or any of their Subsidiaries or Affiliates for services in connection
with this Agreement or otherwise without having to account for the same to the
Lenders.

         7.8. RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative Agent may
resign at any time by giving notice thereof to the Lenders and the Borrower. In
the event that the Administrative Agent shall neither be a Lender nor a Holder
under the Operative Agreements, the Lessee may require the Administrative Agent
to resign. Upon any such resignation, the Majority Lenders shall have the right
to appoint (with the consent of the Lessee so long as there shall not have
occurred and be continuing a Lease Default or Lease Event of Default, which
consent shall not be unreasonably withheld) a successor Administrative Agent. If
no successor Administrative Agent shall have been so appointed by the Majority
Lenders and shall have accepted such appointment within thirty (30) days after
the retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent which shall be a commercial bank organized under the laws
of the United States of America having combined capital and surplus of at least
$500,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor, such successor shall thereupon succeed to and become
vested with all the rights, powers, discretion, privileges, and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this SECTION 7 shall continue in effect for its benefit in respect
of any actions taken or omitted to be taken by it while it was acting as
Administrative Agent.

              SECTION 8. MATTERS RELATING TO PAYMENT AND COLLATERAL

         8.1.       COLLECTION OF PAYMENTS AND OTHER AMOUNTS.

                    (a) The Lessee has agreed pursuant to the terms of the

         Lessee to the Lessor or the Owner Trustee under the Lease or any other
         Operative Agreement. The Administrative Agent shall, promptly after
         receipt, apply in accordance with the terms of this SECTION 8 any such
         amounts received from the Lessee and all other payments, receipts and
         other consideration received by the Administrative Agent

         pursuant to the Security Agreement or otherwise received by the
         Administrative Agent or any of the Lenders in connection with the
         Collateral, the Security Documents or any of the other Operative
         Agreements.

                    (b) Payments and other amounts received by the
         Administrative Agent from time to time in accordance with the terms of

                  Event of Default has occurred and is continuing, any excess
                  shall be paid to such Person or Persons as the Lessee may
                  designate; PROVIDED that if a Default or Event of Default is
                  in effect, such excess (if any) shall instead be held by the
                  Administrative Agent until the earlier of (I) the first date
                  thereafter on which no Default or Event of Default shall be
                  continuing (in which case such payments shall then be made to
                  such other Person or Persons designated by the Lessee) and
                  (II) the Maturity Date (or, if earlier, the date of any

                  under the Operative Agreements and thereafter as the Borrower
                  and the Holders shall determine.

         disbursement in accordance with the Operative Agreements and if not
         provided for thereunder to such other Person or Persons as the Borrower
         may designate. In the event of an Acceleration it is agreed that, prior
         to the application of amounts received by the Administrative Agent in
         the order described in SECTION 8.1(B) above, any such amounts shall
         first be applied to the payment of (i) any and all sums advanced by the
         Administrative Agent in order to preserve the Collateral or preserve
         its security interest therein, (ii) the reasonable expenses of
         retaking, holding, preparing for sale or lease, selling or otherwise
         disposing or realizing on the Collateral, or of any exercise by the
         Administrative Agent of its rights under the Security Documents,
         together with reasonable attorneys' fees and court costs and (iii) any
         other amounts owed to the Administrative Agent under or in connection
         with the transactions contemplated by the Operative Agreements
         (including without limitation any accrued and unpaid administration
         fees).

         8.2. CERTAIN REMEDIAL MATTERS. Notwithstanding any other provision of
this Agreement or any other Credit Document:

                    (a) the Borrower shall at all times retain all rights to
         Excepted Payments payable to or for the account of the Owner Trustee or
         any of the Holders and to demand, collect or commence an action at law
         to obtain such payments and to enforce any judgment with respect
         thereto (but not to terminate the Lease as a result thereof); and


                                       25


<PAGE>



                    (b) the Borrower shall at all times retain the right, but
         not to the exclusion of the Administrative Agent, (A) to receive from
         the Lessee all notices, certificates and other documents and all
         information that the Lessee is permitted or required to give or furnish
         to the Borrower or the Lessor pursuant to the Lease, the Participation
         Agreement or any other Operative Agreement, (B) to retain all rights
         with respect to insurance that ARTICLE XIV of the Lease specifically
         confers upon the "Lessor", (C) to provide such insurance as the Lessee
         shall have failed to maintain or as the Borrower may desire, and (D) to
         enforce compliance by the Lessee with the provisions of ARTICLES VIII,
         IX, X, XI, XIV AND XVII of the Lease.

         8.3. RELEASE OF PROPERTIES, ETC. If the Lessee shall at any time
purchase any Property pursuant to the terms of the Lease, or the Construction
Agent shall purchase any Property pursuant to the Agency Agreement, or if any
Property shall be sold in accordance with ARTICLE XXII of the Lease, then, upon
satisfaction by the Borrower of its obligation to prepay the Loans and to pay
accrued interest on the Loans so prepaid pursuant to SECTION 2.6, the
Administrative Agent is hereby authorized to release such Property from the
Liens created by the Security Documents. In addition, upon the termination of
the Commitments and the payment in full of the Loans and all other amounts owing
by the Borrower, the Lessee and the Construction Agent hereunder or under any
other Operative Agreement the Administrative Agent is hereby authorized to
release all of the Properties from the Liens created by the Security Documents;
provided that such payment shall be sufficient to pay in full the Loans and all
other amounts owing by the Borrower, the Lessee or the Construction Agent
hereunder or under the other Operative Agreements. Upon request of the Borrower
or the Lessee following any such release, the Administrative Agent shall, at the
sole cost and expense of the Borrower or the Lessee, execute and deliver to the
Borrower or the Lessee such documents as the Borrower or the Lessee shall
reasonably request to evidence such release.

         8.4. EXCEPTED PAYMENTS. Notwithstanding any other provision of this
Agreement or the Security Documents, any Excepted Payment received at any time
by the Administrative Agent shall be distributed promptly to the Person entitled
to receive such Excepted Payment.

                            SECTION 9. MISCELLANEOUS

         9.1. AMENDMENTS AND WAIVERS. Neither this Agreement nor any other
Credit Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this SECTION 9.1. The
Majority Lenders may, or, with the written consent of the Majority Lenders, the
Administrative Agent may, from time to time, (a) enter into written agreements
with the Borrower, amending, modifying or supplementing the Credit Documents for
the purpose of adding any provisions to the Credit Documents or changing in any
manner the rights of the Administrative Agent, the Lenders or the Borrower
thereunder or (b) waive, on such terms and conditions as the Majority Lenders
may specify in such instrument, any of the requirements of the Credit Documents
or any Default or Event of Default and its consequences. In addition, the
Administrative Agent may from time to time consent in writing to amendments,
supplements, modifications or waivers with respect to any Operative Agreement
(other than the Credit Documents but including the Guaranty Agreement), subject
to receipt of the prior written consent of the Majority Lenders; PROVIDED,
HOWEVER, that so long as the Administrative Agent has no actual knowledge of the
existence of an Event of Default the Administrative Agent may grant waivers or
consents with

                                       26


<PAGE>



respect to the terms and requirements of the Participation Agreement without the
prior consent of the Lenders (as such authority of the Administrative Agent is
more specifically described in SECTION 7.1 hereof). Notwithstanding the
foregoing, no such amendment, supplement, modification or waiver shall (i)
reduce the amount or extend the scheduled date of maturity of any Note, or
reduce the stated rate of any interest payable hereunder (other than as a result
of waiving the applicability of any post default increase in interest rates) or
any Unused Fees payable under the Participation Agreement, or extend the
scheduled date of any payment of such interest or Unused Fees, or increase the
amount or extend the expiration date of any Lender's Commitment, or permit any
Loan by any Lender in excess of its Commitment, or elect to decline the funding
of any fees, taxes, expenses, disbursements, Transaction Expenses or
indemnifying payments (as described in SECTIONS 9.1(A), 9.1(B) or 13.5), in each
case without the consent of each Lender directly affected thereby, or (ii)
amend, modify or waive any provision of this SECTION 9.1 or reduce the
percentage specified in the definition of Majority Lenders, or consent to the
assignment or transfer by the Borrower of or release the Borrower from any of
its rights and obligations under the Credit Documents, or release a material
portion of the Collateral (except in accordance with SECTION 8.3), or release
the Lessee from its obligations under the Lease, or release any Guarantor from
its obligations under the Guaranty, or otherwise alter any payment obligations
of the Lessee to the Lessor or the Lessor to the Administrative Agent or the
Lenders under the Operative Agreements, in each case without the written consent
of all the Lenders, or (iii) amend, modify or waive any provision of SECTION 7
without the written consent of the then Administrative Agent. Any such waiver,
amendment, supplement or modification shall be binding upon the Borrower, the
Lessee, the Lenders and the Administrative Agent and all future holders of the
Notes. In the case of any waiver, the Borrower, the Lessee, the Lenders and the
Administrative Agent shall be restored to their former position and rights under
the Credit Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent
thereon.

         9.2. NOTICES. All notices, requests and demands to or upon the
respective parties hereto shall be in writing and, unless otherwise expressly

delay in exercising, on the part of the Administrative Agent or any Lender, any
right remedy, power or privilege hereunder or under the other Credit Documents

<PAGE>



not assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of each Lender.

         9.7. PARTICIPATIONS. Any Lender may, in the ordinary course of its
business and in accordance with applicable law, at any time sell to one or more
banks, financial institutions or other entities (each, a "Participant")
participating interests in any Loan owing to such Lender, the Notes held by such
Lender, any Commitment of such Lender or any other interest of such Lender
hereunder and under the other Operative Agreements; PROVIDED that any such sale
of a participating interest shall be in a principal amount of at least
$5,000,000. In the event of any such sale by a Lender of a participating
interest to a Participant, such Lender's obligations under this Agreement shall
remain unchanged, such Lender shall remain solely responsible for the
performance thereof, such Lender shall remain the holder of any such Note for
all purposes under this Agreement and the Notes, and the Borrower and the
Administrative Agent shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under this Agreement and
the Notes. In no event shall any Participant have any right to approve any
amendment or waiver of any provision of this Agreement or any other Operative
Agreement, or any consent to any departure by the Borrower or any other Person
therefrom, except to the extent that such amendment, waiver or consent would (a)
reduce the principal of, or interest on, any Loan or Note, or postpone the date
of the final maturity of any Loan or Note, or reduce the amount of any Unused
Fee, in each case to the extent subject to such participation or (b) release all
or substantially all of the Collateral.

         9.8. ASSIGNMENTS; ADDITIONAL COMMITMENT.

                    (a) Any Lender may, in accordance with applicable law, at
         any time and from time to time assign to any Lender or any affiliate of
         any Lender or, with the consent (subject to SECTION 11.1 of the
         Participation Agreement) of the Borrower and the Administrative Agent
         (which in each case shall not be unreasonably withheld, conditioned or
         delayed), to an additional bank, financial institution or other entity
         that (i) is either organized under the laws of the United States or any
         state thereof or is a foreign bank that operates a branch office in the
         United States and (ii) in either case, is not the Lessee or any
         affiliate of the Lessee, (each such permitted assignee being referred
         to as a "Purchasing Lender"), all or any part of its rights and
         obligations under this Agreement and the other Operative Agreements
         pursuant to an Assignment and Acceptance, substantially in the form of
         EXHIBIT C, executed by such Purchasing Lender, such assigning Lender
         (and, in the case of a Purchasing Lender that is not a Lender or an
         affiliate thereof, subject to SECTION 11.1 of the Participation
         Agreement, by the Borrower and the Administrative Agent) and delivered
         to the Administrative Agent for its acceptance and recording in the
         Register; PROVIDED that no such assignment to a Purchasing Lender
         (other than any Lender or any affiliate thereof) of the Commitments
         hereunder shall be in an aggregate principal amount less than
         $5,000,000 (other than in the case of an assignment of all of a
         Lender's interests under this Agreement and the Notes), and PROVIDED
         FURTHER that the assigning Lender shall simultaneously assign to the
         same Purchasing Lender the same percentage of the assigning Lender's
         rights and obligations under each of the Operative Agreements (with
         respect to each of the Series A Loans and the Series B Loans). Upon
         such execution, delivery, acceptance and recording, from and after the
         effective date determined pursuant to such Assignment and Acceptance,
         (x) the Purchasing Lender

                                       30


<PAGE>



         thereunder shall be a party hereto and, to the extent provided in such
         Assignment and Acceptance, have the rights and obligations of a Lender
         hereunder with a Commitment as set forth therein, and (y) the assigning
         Lender thereunder shall, to the extent provided in such Assignment and
         Acceptance, be released from its obligations under this Agreement (and,
         in the case of an Assignment and Acceptance covering all of the
         remaining portion of an assigning Lender's rights and obligations under
         this Agreement, such assigning Lender shall cease to be a party
         hereto). Notwithstanding anything to the contrary in this Agreement,
         the consent of the Borrower shall not be required, and, unless
         requested by the relevant Purchasing Lender or assigning Lender, new
         Notes shall not be required to be executed and delivered by the
         Borrower, for any assignment which occurs at any time when any of the
         events described in SECTION 6(G) shall have occurred and be continuing.

                    (b) Upon its receipt of an Assignment and Acceptance
         executed by an assigning Lender and a Purchasing Lender (and, in the
         case of a Purchasing Lender that is not a Lender or an affiliate
         thereof, by the Borrower and the Administrative Agent) together with
         payment to the Administrative Agent of a registration and processing
         fee of $3,500 (which shall not be payable by the Borrower, except in
         connection with an assignment requested in accordance with SECTION
         2.14(B)), the Administrative Agent shall (i) promptly accept such
         Assignment and Acceptance and (ii) promptly after the effective date
         determined pursuant thereto, record the information contained therein
         in the Register and give notice of such acceptance and recordation to
         the Lenders and the Borrower on or prior to such effective date, the
         Borrower, at its own expense, shall execute and deliver to the
         Administrative Agent new Notes (in exchange for the Notes of the
         assigning Lender), each in an amount equal to the Commitment assumed or
         Loans purchased by the relevant Purchasing Lender pursuant to such
         Assignment and Acceptance, and, if the assigning Lender has retained a
         Commitment or any Loan hereunder, new Notes to the order of the
         assigning Lender, each in an amount equal to the Commitment or Loans
         retained by it hereunder. Such new Notes shall be dated the Effective
         Date and shall otherwise be in the form of the Notes replaced thereby.

                    (c) Each Purchasing Lender (other than any Lender organized
         and existing under the laws of the U.S. or any state thereof, or any
         political subdivision of the U.S. or of any such state), by executing
         and delivering an Assignment and Acceptance,

                              (i) agrees to execute and deliver to the
                    Administrative Agent, as promptly as practicable, four
                    signed copies (two for the Administrative Agent and two for
                    delivery by the Administrative Agent to the Borrower) of IRS
                    Form 1001, Form 4224 or Form W-8 (or any successor form or
                    comparable form) claiming complete exemption from
                    withholding and deduction for or on account of U.S. Federal
                    taxes on or in respect of payments of principal and interest
                    under or in respect of this Agreement (it being understood
                    that if the applicable form is not so delivered, payments
                    under or in respect of this Agreement may be subject to
                    withholding and deduction);

                             (ii) represents and warrants to the Borrower and
                    the Administrative Agent that the form so delivered is true
                    and accurate and that, as of the effective

                                       31


<PAGE>



                    date of the applicable Assignment and Acceptance, each of
                    such Purchasing Lender's Lending Offices is entitled to
                    receive payments of principal and interest under or in
                    respect of this Agreement without withholding or deduction
                    for or on account of any taxes imposed by the U.S. Federal
                    government;

                             (iii) agrees to deliver annually hereafter to each
                    of the Borrower and the Administrative Agent not later than
                    December 31 of the year preceding the year to which it will
                    apply, two further properly completed signed copies of IRS
                    Form 1001, Form 4224 or Form W-8 (or any successor form or
                    comparable form), as appropriate, unless an event has
                    occurred which renders the relevant form inapplicable (it
                    being understood that if the applicable form is not so
                    delivered, payments under or in respect of this Agreement
                    may be subject to withholding and deduction);

                             (iv) agrees to promptly notify the Borrower and the
                    Administrative Agent in writing if it ceases to be entitled
                    to receive payments of principal and interest under or in
                    respect of this Agreement without withholding or deduction
                    for or on account of any taxes imposed by the U.S. or any
                    political subdivision in or of the U.S. (it being understood
                    that payments under or in respect of this Agreement may be
                    subject to withholding and deduction in such event);

                              (v) acknowledges that in the event it ceases to be
                    exempt from withholding or deduction of such taxes, the
                    Administrative Agent may withhold or deduct the applicable
                    amount from any payments to which such assignee Lender would
                    otherwise be entitled, without any liability to such
                    assignee Lender therefor; and

                             (vi) agrees to indemnify the Borrower and the
                    Administrative Agent from and against any and all
                    liabilities, obligations, losses, damages, penalties,
                    actions, judgments, suits, costs or expenses that result
                    from such assignee Lender's breach of any such
                    representation, warranty or agreement.

                    (d) Any Lender party to this Agreement may, from time to
         time and without the consent of the Borrower or any other Person,
         pledge or assign for security purposes any portion of its Loans or any
         other interests in this Agreement and the other Credit Documents to any
         Federal Reserve Bank.

         9.9. THE REGISTER; DISCLOSURE. The Administrative Agent shall maintain
at its address referred to in SECTION 9.2 a copy of each Assignment and
Acceptance delivered to it and a register (the "Register") for the recordation
of the names and addresses of the Lenders, the Commitments of the Lenders, and
the principal amount of the Loans by Series owing to each Lender from time to
time. The entries in the Register shall be conclusive, in the absence of clearly
demonstrable error, and the Borrower, the Administrative Agent and the Lenders
may treat each Person whose name is recorded in the Register as the owner of the
Loan recorded therein for all purposes of this Agreement. The

                                       32


<PAGE>



Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable notice.

         9.10.      ADJUSTMENTS; SET-OFF.

                    (a) If any Lender (a "BENEFITTED LENDER") shall at any time
         receive any payment of all or part of its Loans, or interest thereon,
         or receive any collateral in respect thereof (whether voluntarily or
         involuntarily, by set-off, pursuant to events or proceedings of the
         nature referred to in SECTION 6(G), or otherwise), in a greater
         proportion than any such payment to or collateral received by any other
         Lender, if any, in respect of such other Lender's Loans, or interest
         thereon, such Benefitted Lender shall purchase for cash from the other
         Lenders a participating interest in such portion of each such other
         Lender's Loans, or shall provide such other Lenders with the benefits
         of any such collateral, or the proceeds thereof, as shall be necessary
         to cause such Benefitted Lender to share the excess payment or benefits
         of such collateral or proceeds ratably with each of the Lenders as to
         each Category of Loans; PROVIDED, HOWEVER, that if all or any portion
         of such excess payment or benefit is thereafter recovered from such
         Benefitted Lender, such purchase shall be rescinded, and the purchase
         price and benefits returned, to the extent of such recovery, but
         without interest. The Borrower agrees that any Lender so purchasing a
         participation from a Lender pursuant to this SECTION 9.10 may, to the
         fullest extent permitted by law, exercise all of its rights of payment
         (including the right of set-off) with respect to such participation as
         fully as if such Person were the direct creditor of the Borrower in the
         amount of such participation.

                    (b) 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 of an Event of Default, each of the
         Administrative Agent and each Lender is hereby authorized at any time
         or from time to time, without presentment, demand, protest or other
         notice of any kind to the Borrower or to 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 Administrative Agent or
         such Lender (including, without limitation, by branches and agencies of
         the Administrative Agent or such Lender wherever located) to or for the
         credit or the account of the Borrower against and on account of the
         obligations and liabilities of the Borrower to the Administrative Agent
         or such Lender under this Agreement or under any of the other Operative
         Agreements, including, without limitation, all interests in obligations
         of the Borrower purchased by any such Lender pursuant to SECTION
         9.10(A), and all other claims of any nature or description arising out
         of or connected with this Agreement or any other Operative Agreement,
         irrespective or whether or not the Administrative Agent or such Lender
         shall have made any demand and although said obligations, liabilities
         or claims, or any of them, shall be contingent or unmatured.

         9.11. COUNTERPARTS. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by telefacsimile), and all of said counterparts taken together shall be deemed
to constitute one and the same instrument. A set of the copies of this Agreement
signed by all the parties shall be lodged with the Borrower and the
Administrative Agent.

         9.12. SEVERABILITY. Any provision of this Agreement 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.

         9.13. INTEGRATION. This Agreement and the other Operative Documents
represent the agreement of the Borrower, the Administrative Agent, and the
Lenders with respect to the subject mater hereof, and there are no promises,
undertakings, representations or warranties by the Administrative Agent or any
Lender relative to subject matter hereof not expressly set forth or referred to
herein or in the other Operative Documents.

         9.14. GOVERNING LAW; WAIVER OF JURY TRIAL.

                    (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
         INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF FLORIDA,
         WITHOUT REGARD TO ANY OTHERWISE APPLICABLE PRINCIPLES OF CONFLICT OF
         LAWS.

                    (b) TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, EACH
         OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY
         JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AND
         FOR ANY COUNTERCLAIM THEREIN.

         9.15. SUBMISSION TO JURISDICTION; WAIVERS. The Borrower hereby
irrevocably and unconditionally:

                    (a) submits for itself and its property in any legal action
         or proceeding relating to this Agreement and the other Credit Documents
         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 Courts of the State of Florida and the courts of the United
         States of America, in each case sitting in Broward County, Florida, and
         appellate courts from any thereof;

                    (b) consents that any such action or proceeding may be
         brought in such courts and waives any objection that it may now or
         hereafter have to the venue of any such action or proceeding in any
         such court or that such action or proceeding was brought in an
         inconvenient court and agrees not to plead or claim the same,

                    (c) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail) postage
         prepaid, to the Borrower at its address set forth in SECTION 9.2 or at
         such other address of which the Administrative Agent shall have been
         notified pursuant thereto;

                                       34


<PAGE>



                    (d) 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 to sue in any other jurisdiction; and

                    (e) waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this SECTION 9.15 any special, exemplary, punitive or
         consequential damages.

         9.16. ACKNOWLEDGMENTS. Borrower hereby acknowledges that:

                    (a) neither the Administrative Agent nor any Lender has any
         fiduciary relationship with or duty to the Borrower arising out of or
         in connection with this Agreement or any of the other Credit Documents,
         and the relationship between the Administrative Agent and the Lenders,
         on one hand, and the Borrower, on the other hand, in connection
         herewith or therewith is solely that of debtor and creditor; and

                    (b) no joint venture is created hereby or by the other
         Credit Documents or otherwise exists by virtue of the transactions
         contemplated hereby among the Lenders or among the Borrower and the
         Lenders.

         9.17. NONRECOURSE. Anything to the contrary contained in this Agreement
or in any other Operative Agreement notwithstanding, neither the Borrower nor
any Holder nor any officer, director or shareholder thereof, nor any of the
Borrower's successors or assigns (all such Persons being hereinafter referred to
collectively as the "Exculpated Persons"), shall be liable in its individual
capacity in any respect for any liability or obligation hereunder or under any
other Operative Agreement including the payment of the principal of, or interest
on, the Notes, or for monetary damages for the breach of performance of any of
the covenants contained in this Agreement, the Notes or any of the other
Operative Agreements. The Administrative Agent and the Lenders agree that, in
the event any of them pursues any remedies available to them under this
Agreement, the Notes or any other Operative Agreement, neither the
Administrative Agent nor the Lenders shall have any recourse against the
Borrower, in its individual capacity, nor any other Exculpated Person, for any
deficiency, loss or claim for monetary damages or otherwise resulting therefrom
and recourse shall be had solely and exclusively against the Trust Estate and
the Lessee; but nothing contained herein shall be taken to prevent recourse
against or the enforcement of remedies against the Trust Estate in respect of
any and all liabilities, obligations and undertakings contained in this
Agreement, the Notes or any other Operative Agreement. Notwithstanding the
provisions of this Section, nothing in this Agreement, the Participation
Agreement, the Notes, the Security Agreement, the Mortgage Instruments or any
other Operative Agreement shall: (a) constitute a waiver, release or discharge
of any indebtedness or obligation evidenced by the Notes or arising under this
Agreement, the Security Agreement, the Mortgage Instruments or the Participation
Agreement or secured by the Security Agreement, the Mortgage Instruments or any
other Operative Agreement, but the same shall continue until paid or discharged;
(b) relieve the Lessor or any Exculpated Person from liability and
responsibility for (but only to the extent of the damages arising by reason of):
(i) active waste knowingly committed by the Lessor or any Exculpated Person with
respect to the Properties or (ii) any fraud, gross negligence, willful
misconduct or willful breach on the part of the Lessor or any such

                                       35


<PAGE>



Exculpated Person; (c) relieve the Lessor or any Exculpated Person from
liability and responsibility for (but only to the extent of the moneys
misappropriated, misapplied or not turned over) (i) misappropriation or
misapplication by the Lessor (i.e., application in a manner contrary to any
Operative Agreement) of any insurance proceeds or condemnation award paid or
delivered to the Lessor by any Person other than the Agent, (ii) any deposits or
any escrows or amounts owed by the Lessee under the Agency Agreement held by the
Lessor or (iii) any rents or other income received by the Lessor from the Lessee
that are not turned over to the Agent; or (d) affect or in any way limit the
Agent's rights and remedies under any Operative Agreement with respect to the
Rents and its rights and powers thereunder or to obtain a judgment against the
Lessor's interest in the Properties.

         9.18. USURY SAVINGS CLAUSE. Notwithstanding any other provision herein,
the aggregate interest rate charged under any of the Notes, including all
charges or fees in connection therewith deemed in the nature of interest under
applicable law shall not exceed the Highest Lawful Rate (as such term is defined
below). If the rate of interest (determined without regard to the preceding
sentence) under this Agreement or any other Operative Agreement at any time
exceeds the Highest Lawful Rate (as defined below), the outstanding amount of
the Loans made hereunder shall bear interest at the Highest Lawful Rate until
the total amount of interest due hereunder equals the amount of interest which
would have been due hereunder if the stated rates of interest set forth in this
Agreement and the other Operative Agreements had at all times been in effect. In
addition, if when the Loans made hereunder are repaid in full the total interest
due hereunder and under the other Operative Agreements (taking into account the
increase provided for above) is less than the total amount of interest which
would have been due hereunder and thereunder if the stated rates of interest set
forth in this Agreement and in such Operative Agreements had at all times been
in effect, then to the extent permitted by law, the Borrower shall pay to the
Agent an amount equal to the difference between the amount of interest paid and
the amount of interest which would have been paid if the Highest Lawful Rate had
at all times been in effect. Notwithstanding the foregoing, it is the intention
of the Lenders and the Borrower to conform strictly to any applicable usury
laws. Accordingly, if any Lender contracts for, charges, or receives any
consideration which constitutes interest in excess of the Highest Lawful Rate,
then any such excess shall be cancelled automatically and, if previously paid,
shall at such Lender's option be applied to the outstanding amount of the Loans
made hereunder or be refunded to the Borrower. As used in this paragraph, the
term "Highest Lawful Rate" means the maximum lawful interest rate, if any, that
at any time or from time to time may be contracted for, charged, or received
under the laws applicable to such Lender which are presently in effect or, to
the extent allowed by law, under such applicable laws which may hereafter be in
effect and which allow a higher maximum nonusurious interest rate than
applicable laws now allow.

Lessor or the name of Lessee or otherwise, to execute any Lease Supplement which
Lessee fails or refuses to sign in accordance with the terms of this SECTION
2.4.

                                   ARTICLE III

         3.1 RENT.

                  (a) Lessee shall pay Basic Rent on each Payment Date, and on
         any date on which this Lease shall terminate with respect to any or all
         Properties during the Term; provided, however, with respect to each
         individual Property Lessee shall have no obligation to pay Basic Rent
         with respect to such Property until the earlier of (i) the Completion
         Date for such Property or (ii) if such Property is a Construction
         Period Property as of the date of any Agency Agreement Event of
         Default, the date of such Agency Agreement Event of Default (in each
         case, such earlier date being referred to as the "Basic Rent
         Commencement Date").

                  (b) Basic Rent shall be due and payable in lawful money of the
         United States and shall be paid in immediately available funds on the
         due date therefor (or within the applicable grace period) to such
         account or accounts as Lessor shall from time to time direct.

                  (c) Lessee's inability or failure to take possession of all or
         any portion of any Property when delivered by Lessor, whether or not
         attributable to any act or omission of the Lessor, the Construction
         Agent, Lessee, or any other Person, or for any other reason whatsoever,
         shall not delay or otherwise affect Lessee's obligation to pay Rent for
         such Property in accordance with the terms of this Lease.

                                        2

         3.2 PAYMENT OF BASIC RENT. Basic Rent shall be paid absolutely net to
Lessor or its designee, so that this Lease shall yield to Lessor the full amount
of Basic Rent, without setoff, deduction or reduction.

         3.3 SUPPLEMENTAL RENT. Lessee shall pay to Lessor or its designee or to
the Person entitled thereto any and all Supplemental Rent promptly as the same
shall become due and payable, and if Lessee fails to pay any Supplemental Rent,
Lessor shall have all rights, powers and remedies provided for herein or by law
or equity or otherwise in the case of nonpayment of Basic Rent. Without limiting
the generality of the definition of "Supplemental Rent," Lessee shall pay to
Lessor as Supplemental Rent, among other things, on demand, to the extent
permitted by applicable Legal Requirements, (a) any and all unpaid Unused Fees,
Holder Unused Fees, Owner Trustee fees, other fees, charges, prepayment
penalties, Taxes, insurance costs, indemnities, expenses, payments and other
obligations (except the obligations of Lessor to pay the principal amount of the
Loans and the Holder Amount) due and owing by Lessor under the Credit Agreement,
the Trust Agreement or any other Operative Agreement (including specifically
without limitation any amounts owing to the Lenders under SECTION 2.11 or
SECTION 2.12 of the Credit Agreement and any amounts owing to the Holders under
SECTION 3.9 or SECTION 3.10 of the Trust Agreement) and (b) interest at the
applicable Overdue Rate on any installment of Basic Rent not paid when due
(subject to the applicable grace period) for the period for which the same shall
be overdue and on any payment of Supplemental Rent not paid when due or demanded
by the appropriate Person for the period from the due date or the date of any
such demand, as the case may be, until the same shall be paid. The expiration or
other termination of Lessee's obligations to pay Basic Rent hereunder shall not
limit or modify the obligations of Lessee with respect to Supplemental Rent.
Unless expressly provided otherwise in this Lease, in the event of any failure
on the part of Lessee to pay and discharge any Supplemental Rent as and when
due, Lessee shall also promptly pay and discharge any fine, penalty, interest or
cost which may be assessed or added, pursuant to any Operative Agreement or
otherwise, in each case for nonpayment or late payment of such Supplemental
Rent, all of which shall also constitute Supplemental Rent.

         3.4 PERFORMANCE ON A NON-BUSINESS DAY. If any Basic Rent is required
hereunder on a day that is not a Business Day, then such Basic Rent shall be due
on the corresponding Scheduled Interest Payment Date. If any Supplemental Rent
is required hereunder on a day that is not a Business Day, then such
Supplemental Rent shall be due on the next succeeding Business Day.

         3.5 RENT PAYMENT PROVISIONS. Lessee shall make payment of all Basic
Rent and Supplemental Rent when due regardless of whether any of the Operative
Agreements pursuant to which same is calculated and is owing shall have been
rejected, avoided or disavowed in any bankruptcy or insolvency proceeding
involving any of the parties to any of the Operative Agreements. Such provisions
of such Operative Agreements and their related definitions are incorporated
herein by reference and shall survive any termination, amendment or rejection of
any such Operative Agreements.

                                   ARTICLE IV

         4.1 UTILITY CHARGES; TAXES. Lessee shall pay or cause to be paid all
charges for electricity, power, gas, oil, water, telephone, sanitary sewer
service and all other rents and utilities used in or on a Property and related
real property during the Term. Lessee shall be entitled to receive any credit or
refund with respect to any utility charge paid by Lessee, PROVIDED THAT Lessee
must collect any such credit or refund from Lessor or the respective utility
company (as the case may be) and shall not be entitled to offset any such amount
owed to Lessee against Rent payable by the Lessee hereunder. Unless a Lease
Default or Lease Event of Default shall have occurred and be continuing, the
amount of any credit or refund received by Lessor on account of any utility
charges paid by Lessee, net of the costs and expenses incurred by Lessor in
obtaining such credit or refund, shall be promptly paid over to Lessee. In
addition, Lessee shall pay or cause to be paid all taxes or taxes assessments
against a Property. All charges for utilities and all taxes or tax assessments
imposed with respect to a Property for a billing period (or in the cases of tax
assessments, a tax period) during which this Lease expires or terminates shall
be adjusted and prorated on a daily basis between Lessor and Lessee, and each
party shall pay or reimburse the other for such party's pro rata share thereof.

                                    ARTICLE V

         5.1 QUIET ENJOYMENT. Subject to the rights of Lessor contained in
SECTIONS 17.2 AND 17.3 and the other terms of this Lease and the other Operative
Agreements and so long as no Lease Event of Default shall have occurred and be
continuing, Lessee shall peaceably and quietly have, hold and enjoy each
Property for the applicable Term, free of any claim or other action by Lessor or
anyone rightfully claiming by, through or under Lessor (other than Lessee) with
respect to any matters arising from and after the applicable Basic Term
Commencement Date.

                                   ARTICLE VI

         6.1 NET LEASE. This Lease shall constitute a net lease. Any present or
future law to the contrary notwithstanding, this Lease shall not terminate, nor
shall Lessee be entitled to any abatement, suspension, deferment, reduction,
setoff, counterclaim, or defense with respect to the Rent, nor shall the
obligations of Lessee hereunder be affected (except as expressly herein
permitted and by performance of the obligations in connection therewith) by
reason of: (a) any damage to or destruction of any Property or any part thereof;
(b) any taking of any Property or any part thereof or interest therein by
Condemnation or otherwise; (c) any prohibition, limitation, restriction or
prevention of Lessee's use, occupancy or enjoyment of any Property or any part
thereof, or any interference with such use, occupancy or enjoyment by any Person
or for any other reason; (d) any title defect, Lien or any matter affecting
title to any Property; (e) any eviction by paramount title or otherwise; (f) any
default by Lessor hereunder; (g) any action for bankruptcy, insolvency,
reorganization, liquidation, dissolution or other proceeding relating to or
affecting the Agent, any Lender, Lessor, Lessee, any Holder or any Governmental
Authority; (h) the impossibility or illegality of performance by Lessor, Lessee
or both; (i) any action of any Governmental Authority or any other Person; (j)
Lessee's acquisition of ownership of all or part of any Property; (k) breach of
any warranty or representation with respect to any Property or any Operative
Agreement; (l) any defect in the condition, quality or fitness for use of any
Property or any part thereof; or (m) any other cause or

                                        4

<PAGE>

circumstance whether similar or dissimilar to the foregoing and whether or not
Lessee shall have notice or knowledge of any of the foregoing. The foregoing
clause (j) shall not prevent the termination of the Lease in accordance with the
terms hereof if the Lessee purchases all of the Properties pursuant to SECTION
20.1. The parties intend that the obligations of Lessee hereunder shall be
covenants, agreements and obligations that are separate and independent from any
obligations of Lessor hereunder and shall continue unaffected unless such
covenants, agreements and obligations shall have been modified or terminated in
accordance with an express provision of this Lease. Lessor and Lessee
acknowledge and agree that the provisions of this SECTION 6.1 have been
specifically reviewed and subject to negotiation.

         6.2 NO TERMINATION OR ABATEMENT. Lessee shall remain obligated under
this Lease in accordance with its terms and shall not take any action to
terminate, rescind or avoid this Lease, notwithstanding any action for
bankruptcy, insolvency, reorganization, liquidation, dissolution, or other
proceeding affecting Lessor, any other Person or any Governmental Authority, or
any action with respect to this Lease or any Operative Agreement which may be
taken by any trustee, receiver or liquidator of Lessor, any other Person or any
Governmental Authority or by any court with respect to Lessor, any other Person
or any Governmental Authority. Lessee hereby waives all right (a) to terminate
or surrender this Lease (except as permitted under the terms of the Operative
Agreements) or (b) to avail itself of any abatement, suspension, deferment,
reduction, setoff, counterclaim or defense with respect to any Rent. Lessee
shall remain obligated under this Lease in accordance with its terms and Lessee
hereby waives any and all rights now or hereafter conferred by statute or
otherwise to modify or to avoid strict compliance with its obligations under
this Lease. Notwithstanding any such statute or otherwise, Lessee shall be bound
by all of the terms and conditions contained in this Lease.

                                   ARTICLE VII

         7.1      OWNERSHIP OF THE PROPERTIES.

                  (a) Lessor and Lessee intend that for federal and all state
         and local income tax purposes and other tax purposes, for bankruptcy
         purposes, creditor's rights purposes, environmental law purposes, for
         purposes of exercising remedies against the Lessee, the Construction
         Agent or the Properties, and for all other legal purposes (A) this
         Lease will be treated as a loan and financing arrangement and not a
         true lease, (B) Lessee will be treated as the owner of the Properties
         and will be entitled to all tax benefits ordinarily available to owners
         of property similar to the Properties for such tax purposes, and (C)
         all payments of Basic Rent shall be deemed to be interest payments.
         Consistent with the foregoing, Lessee intends to claim depreciation and
         cost recovery deductions associated with the Property, and Lessor
         agrees not to take any inconsistent position on its income tax returns.
         Neither Lessor, the Agent, any Lender, any Holder nor NMS makes any
         representation or warranty with respect to the foregoing matters
         described in this SECTION 7.1 and will assume no liability for the
         Lessee's accounting treatment of this transaction.

                  (b) Lessor and Lessee further intend and agree that, for the
         purpose of securing Lessee's obligations hereunder, (i) this Lease
         shall be deemed to be a security agreement and

                                        5

<PAGE>

         financing statement within the meaning of Article 9 of the Uniform
         Commercial Code respecting each of the Properties to the extent such is
         personal property and an irrevocable grant and conveyance of a lien and
         mortgage on each of the Properties to the extent such is real property;
         (ii) the acquisition of title (or to the extent applicable, a leasehold
         interest) in each Property referenced in ARTICLE II shall be deemed to
         be (A) a grant by Lessee to Lessor of a lien on and security interest
         in all of Lessee's right, title and interest in and to each Property
         and all proceeds (including without limitation insurance proceeds) of
         any of the Property, whether in the form of cash, investments,
         securities or other property, and (B) an assignment by Lessee to Lessor
         of all rents, profits and income produced by any of the Property; and
         (iii) notifications to Persons holding such property, and
         acknowledgments, receipts or confirmations from financial
         intermediaries, bankers or agents (as applicable) of Lessee shall be
         deemed to have been given for the purpose of perfecting such security
         interest under applicable law. Lessor and Lessee shall promptly take
         such actions as may be necessary or advisable in either party's opinion
         (including without limitation the filing of Uniform Commercial Code
         Financing Statements or Uniform Commercial Code Fixture Filings) to
         ensure that the lien and security interest in each Property will be
         deemed to be a perfected lien and security interest of first priority
         under applicable law and will be maintained as such throughout the
         Term.

                  (c) The Lessor agrees that it will not assert against any
         inventory or equipment of the Lessee (other than equipment constituting
         Collateral under the Operative Agreements) any statutory or possessory
         lien including, without limitation, rights of levy or distraint for
         rent, all of which it hereby waives. The foregoing notwithstanding, the
         Lessor retains the right to assert any such liens and rights against
         any property of the Lessee that constitutes Collateral (including
         without limitation any Property, Land, Equipment and Improvements, and
         any proceeds of the foregoing).

                                  ARTICLE VIII

         8.1 CONDITION OF THE PROPERTIES. LESSEE ACKNOWLEDGES AND AGREES THAT IT
IS LEASING EACH PROPERTY "AS IS" WITHOUT REPRESENTATION, WARRANTY OR COVENANT
(EXPRESS OR IMPLIED) BY LESSOR AND IN EACH CASE SUBJECT TO (A) THE EXISTING
STATE OF TITLE, (B) THE RIGHTS OF ANY PARTIES IN POSSESSION THEREOF (IF ANY),
(C) ANY STATE OF FACTS WHICH AN ACCURATE SURVEY OR PHYSICAL INSPECTION MIGHT
SHOW, (D) ALL APPLICABLE LEGAL REQUIREMENTS AND (E) VIOLATIONS OF LEGAL
REQUIREMENTS WHICH MAY EXIST ON THE DATE OF THE APPLICABLE LEASE SUPPLEMENT.
NEITHER LESSOR NOR THE AGENT NOR ANY LENDER NOR ANY HOLDER HAS MADE OR SHALL BE
DEEMED TO HAVE MADE ANY REPRESENTATION, WARRANTY OR COVENANT (EXPRESS OR
IMPLIED) OR SHALL BE DEEMED TO HAVE ANY LIABILITY WHATSOEVER AS TO THE TITLE,
VALUE, HABITABILITY, USE, CONDITION, DESIGN, OPERATION, MERCHANTABILITY OR
FITNESS FOR USE OF ANY PROPERTY (OR ANY PART THEREOF), OR ANY OTHER
REPRESENTATION, WARRANTY OR COVENANT WHATSOEVER, EXPRESS OR IMPLIED, WITH
RESPECT TO ANY PROPERTY (OR ANY PART THEREOF), AND NEITHER LESSOR NOR THE AGENT
NOR ANY LENDER NOR ANY HOLDER SHALL BE LIABLE FOR ANY

                                        6

<PAGE>

LATENT, HIDDEN, OR PATENT DEFECT THEREON OR THE FAILURE OF ANY PROPERTY, OR ANY
PART THEREOF, TO COMPLY WITH ANY LEGAL REQUIREMENT. THE LESSEE HAS OR WILL HAVE
BEEN AFFORDED FULL OPPORTUNITY TO INSPECT EACH PROPERTY AND THE IMPROVEMENTS
THEREON (IF ANY), IS OR WILL BE (INSOFAR AS THE LESSOR, THE AGENT, EACH LENDER
AND EACH HOLDER ARE CONCERNED) SATISFIED WITH THE RESULTS OF ITS INSPECTIONS AND
IS ENTERING INTO THIS LEASE SOLELY ON THE BASIS OF THE RESULTS OF ITS OWN
INSPECTIONS, AND ALL RISKS INCIDENT TO THE MATTERS DESCRIBED IN THE PRECEDING
SENTENCE, AS BETWEEN THE LESSOR, THE AGENT, THE LENDERS AND THE HOLDERS, ON THE
ONE HAND, AND THE LESSEE, ON THE OTHER HAND, ARE TO BE BORNE BY LESSEE.

         8.2      POSSESSION AND USE OF THE PROPERTIES.

                  (a) At all times during the Term with respect to each
         Property, such Property shall be used by Lessee in the ordinary course
         of its business. Lessee shall pay, or cause to be paid, all charges and
         costs required in connection with the use of the Properties as
         contemplated by this Lease. Lessee shall not commit or permit any waste
         of the Properties or any part thereof.

                  (b) Lessee represents and warrants that the address stated in
         SECTION 29.1 of this Lease is the chief place of business and chief
         executive office of Lessee (as such terms are used in Section 9-103 of
         the Uniform Commercial Code of any applicable jurisdiction), and Lessee
         will provide Lessor with prior written notice of any change of location
         of its chief place of business or chief executive office. Regarding
         each Property, Lessee represents and warrants that each Lease
         Supplement correctly identifies the initial location of the related
         Equipment and Improvements and contains an accurate legal description
         for the related parcel of Land. Lessee has no other places of business
         where the Equipment or Improvements will be located other than those
         identified on the applicable Lease Supplement.

                  (c) Lessee will not attach or incorporate any item of
         Equipment to or in any other item of equipment or personal property or
         to or in any real property (except the Land identified in the Lease
         Supplement in which such Equipment is also described) in a manner that
         could give rise to the assertion of any Lien (other than a Permitted
         Lien) on such item of Equipment by reason of such attachment or the
         assertion of a claim that such item of Equipment has become a fixture
         and is subject to a Lien in favor of a third party that is prior to the
         Liens thereon created by the Operative Agreements.

                  (d) Each Lease Supplement delivered under the terms of this
         Lease shall contain, in regard to the relevant Property, an Equipment
         Schedule that has a complete description of each item of Equipment, an
         Improvement Schedule that has a complete description of each
         Improvement and a legal description of the Land, to be leased hereunder
         as of such date. Simultaneously with the execution and delivery of each
         Lease Supplement, such Equipment, Improvements and Land shall be deemed
         to have been accepted by Lessee for all purposes of this Lease and to
         be subject to this Lease.

                                        7

<PAGE>

                  (e) At all times during the Term with respect to each
         Property, Lessee will comply with all obligations under, and (to the
         extent no Event of Default has occurred and is continuing and provided
         that such exercise will not impair the value of such Property) shall be
         permitted to exercise all rights and remedies under, all operation and
         easement agreements and related or similar agreements applicable to
         such Property.

                                   ARTICLE IX

         9.1 COMPLIANCE WITH LEGAL REQUIREMENTS AND INSURANCE REQUIREMENTS.
Subject to the terms of ARTICLE XIII relating to permitted contests, Lessee, at
its sole cost and expense, shall (i) comply in all material respects with all
Legal Requirements (including without limitation all Environmental Laws), and
all Insurance Requirements relating to the Properties, including the use,
development, construction, operation, maintenance, repair, refurbishment and
restoration thereof, whether or not compliance therewith shall require
structural or extraordinary changes in the Improvements or interfere with the
use and enjoyment of the Properties, and (ii) procure, maintain and comply in
all material respects with all licenses, permits, orders, approvals, consents
and other authorizations required for the construction, use, maintenance and
operation of the Properties and for the use, development, construction,
operation, maintenance, repair and restoration of the Improvements.

                                    ARTICLE X

         10.1 MAINTENANCE AND REPAIR; RETURN.

                  (a) Lessee, at its sole cost and expense, shall maintain each
         Property in good condition, repair and working order (ordinary wear and
         tear excepted) and make all necessary repairs thereto, of every kind
         and nature whatsoever, whether interior or exterior, ordinary or
         extraordinary, structural or nonstructural, or foreseen or unforeseen,
         in each case as required by all Legal Requirements, Insurance
         Requirements, and manufacturer's specifications and standards and on a
         basis consistent with the operation and maintenance of properties or
         equipment comparable in type and function to the applicable Property
         and in compliance with standard industry practice, subject, however, to
         the provisions of ARTICLE XV with respect to Condemnation and Casualty.

                  (b) Lessee shall not use or locate any component of any
         Property outside of any Approved State. Lessee shall not move or
         relocate any component of any Property beyond the boundaries of the
         Land described in the applicable Lease Supplement without Lessor's
         prior written consent, which consent shall not be unreasonably withheld
         or delayed.

                  (c) If any material component of any Property becomes worn
         out, lost, destroyed, damaged beyond repair or otherwise permanently
         rendered unfit for use, Lessee, at its own expense, will within a
         reasonable time replace such component with a replacement component
         which is free and clear of all Liens (other than Permitted Liens) and
         has a value, utility and useful life at least equal to the component
         replaced. All components which are added to any Property shall
         immediately become the property of, and title thereto shall vest in,
         Lessor, and

                                        8

<PAGE>

         shall be deemed incorporated in such Property and subject to the terms
         of this Lease as if originally leased hereunder.

                  (d) Upon reasonable advance notice, Lessor and its agents
         shall have the right to inspect each Property and all maintenance
         records with respect thereto at any reasonable time during normal
         business hours but shall not materially disrupt the business of Lessee.

                  (e) If, at any time, because of a condemnation, casualty or
         other event or condition, Lessor has reason to believe that the
         appraised value of any Property has materially decreased, then the
         Lessor or the Agent (at Lessee's sole expense) may cause an additional
         Appraisal (addressed to the Lessor and the Agent) to be prepared. In
         addition, Lessor or the Agent (at Lessee's sole expense) may cause to
         be prepared (at Lessee's sole expense) any additional Appraisals (or
         reappraisals) as Lessor or the Agent may deem appropriate (i) if an
         Event of Default has occurred and is continuing, or (ii) if any one of
         Lessor, the Agent, any Lender or any Holder is required pursuant to any
         applicable Legal Requirement to obtain such an Appraisal (or
         reappraisal).

                  (f) Lessor shall under no circumstances be required to build
         any improvements on any Property, make any repairs, replacements,
         alterations or renewals of any nature or description to any Property,
         make any expenditure whatsoever in connection with this Lease or
         maintain any Property in any way. Lessor shall not be required to
         maintain, repair or rebuild all or any part of any Property, and Lessee
         waives the right to (i) require Lessor to maintain, repair, or rebuild
         all or any part of any Property (unless such repairs are needed to cure
         damage to a Property caused by the gross negligence or willful
         misconduct of the Lessor), or (ii) make repairs at the expense of
         Lessor pursuant to any Legal Requirement, Insurance Requirement,
         contract, agreement, covenants, condition or restriction at any time in
         effect.

                  (g) Lessee shall, upon the expiration of the Term or earlier
         termination of this Lease with respect to a Property, if Lessee shall
         not have exercised its Purchase Option with respect to such Property,
         surrender such Property to Lessor, or the third party purchaser, as the
         case may be, subject to Lessee's obligations under this Lease
         (including without limitation SECTIONS 9.1, 10.1(A)-(F), 10.2, 11.1,
         12.1, 22.1 AND 23.1).

         10.2 ENVIRONMENTAL INSPECTION. If (a) Lessee has not given notice of
the exercise of its Purchase Option on the Expiration Date pursuant to SECTION
20.1(B), or (b) Lessee has given notice, pursuant to SECTION 20.1(B) of its
election to remarket the Properties on the Expiration Date or a Payment Date
pursuant to SECTION 22.1 then, in either case, not more than one hundred twenty
(120) days nor less than sixty (60) days prior to such Expiration Date or
Payment Date, Lessee shall, at its sole cost and expense, provide to Lessor and
the Agent a report by a reputable environmental consultant selected by Lessee,
which report shall be in form and substance reasonably satisfactory to Lessor
and the Agent and shall include without limitation a "Phase I" environmental
report (or update of a prior "Phase I" report that was previously delivered to
the Lessor and the Agent) on each of the Properties. If the report delivered
pursuant to the preceding sentence recommends that a "Phase II" report or other
supplemental report be obtained, the Lessee shall, at its own cost and expense,
not

                                        9

<PAGE>

less than thirty (30) days prior to such Expiration Date or Payment Date,
provide to Lessor and the Agent such "Phase II" or other report, in form and
substance reasonably satisfactory to Lessor and the Agent. If Lessee fails to
provide such Phase I, Phase II or other supplemental reports with respect to any
Property within the time periods required by this SECTION 10.2, or if such
report or reports are not satisfactory in scope or content to the Agent or the
Lessor (in their sole discretion), then notwithstanding any other provision of
this Lease, Lessor may require Lessee to purchase all of the Properties on such
Expiration Date or Payment Date for the Termination Value thereof, plus all Rent
due and payable, and all other amounts due and owing under any Operative
Agreement.

                                   ARTICLE XI

         11.1 MODIFICATIONS.

                  (a) Lessee at its sole cost and expense, at any time and from
         time to time without the consent of Lessor may make alterations,
         renovations, improvements and additions to any Property or any part
         thereof and substitutions and replacements therefor (collectively,
         "Modifications") (and shall make any Modification required by
         applicable Legal Requirements); PROVIDED, that: (i) except for any
         Modification required to be made pursuant to a Legal Requirement, no
         Modification shall materially impair the value, utility or useful life
         of any Property from that which existed immediately prior to such
         Modification; (ii) the Modification shall be done expeditiously and in
         a good and workmanlike manner; (iii) Lessee shall comply with all
         material Legal Requirements (including all Environmental Laws) and
         Insurance Requirements applicable to the Modification, including
         without limitation the obtaining of all permits and certificates of
         occupancy, and the structural integrity of any Property shall not be
         adversely affected; (iv) to the extent required by SECTION 14.2(A),
         Lessee shall maintain builders' risk insurance at all times when a
         Modification is in progress; (v) subject to the terms of ARTICLE XIII
         relating to permitted contests, Lessee shall pay all costs and expenses
         and discharge any Liens (other than Permitted Liens) arising with
         respect to the Modification; (vi) such Modification shall comply with
         the requirements of this Lease (including without limitation SECTIONS
         8.2 AND 10.1); and (vii) no Improvements shall be demolished unless
         Lessee shall finance the proposed Modification outside of this lease
         facility. Modifications that (y) are not required for any Property or
         any part thereof pursuant to any Legal Requirement or otherwise and (z)
         are severable from the applicable Property without damage or other loss
         of value to such Property shall become property of the Lessee, and
         title to such Modifications shall rest with the Lessee. Except as set
         forth in the immediately preceding sentence, all Modifications shall
         become property of the Lessor and shall be subject to this Lease, and
         title to any component of any Property comprising any such
         Modifications shall immediately vest in Lessor.

                  (b) The construction process provided for in the Agency
         Agreement is acknowledged by Lessor and the Agent to be consistent with
         and in compliance with the terms and provisions of this ARTICLE XI.

                                   ARTICLE XII

         12.1 WARRANTY OF TITLE.

                  (a) Lessee agrees that, except as otherwise provided herein
         and subject to the terms of ARTICLE XIII relating to permitted
         contests, Lessee shall not directly or indirectly create or allow to
         remain, and shall promptly discharge at its sole cost and expense, (i)
         any Lien, defect, attachment, levy, title retention agreement or claim
         upon any Property or any Modifications or (ii) any Lien, attachment,
         levy or claim with respect to the Rent or with respect to any amounts
         held by the Agent pursuant to the Credit Agreement, in each case other
         than Permitted Liens and Lessor Liens. Lessee shall promptly notify
         Lessor in the event it receives actual knowledge that a Lien other than
         a Permitted Lien or Lessor Lien has occurred with respect to a
         Property, and Lessee represents and warrants to, and covenants with,
         Lessor that the Liens in favor of the Lessor created by the Operative
         Agreements are first priority perfected Liens subject only to Permitted
         Liens.

                  (b) Nothing contained in this Lease shall be construed as
         constituting the consent or request of Lessor, expressed or implied, to
         or for the performance by any contractor, mechanic, laborer,
         materialman, supplier or vendor of any labor or services or for the
         furnishing of any materials for any construction, alteration, addition,
         repair or demolition of or to any Property or any part thereof. NOTICE
         IS HEREBY GIVEN THAT LESSOR IS NOT AND SHALL NOT BE LIABLE FOR ANY
         LABOR, SERVICES OR MATERIALS FURNISHED OR TO BE FURNISHED TO LESSEE, OR
         TO ANYONE HOLDING A PROPERTY OR ANY PART THEREOF THROUGH OR UNDER
         LESSEE, AND THAT NO MECHANIC'S OR OTHER LIENS FOR ANY SUCH LABOR,
         SERVICES OR MATERIALS SHALL ATTACH TO OR AFFECT THE INTEREST OF LESSOR
         IN AND TO ANY PROPERTY.

                                  ARTICLE XIII

         13.1 PERMITTED CONTESTS OTHER THAN IN RESPECT OF INDEMNITIES. Except to
the extent otherwise provided for in SECTION 13 of the Participation Agreement,
Lessee, on its own or on Lessor's behalf but at Lessee's sole cost and expense,
may contest, by appropriate administrative or judicial proceedings conducted in
good faith and with due diligence, the amount, validity or application, in whole
or in part, of any Legal Requirement, or utility charges payable pursuant to
SECTION 4.1 or any Lien, attachment, levy, encumbrance or encroachment, and
Lessor agrees not to pay, settle or otherwise compromise any such item, provided
that (a) the commencement and continuation of such proceedings shall suspend the
collection of any such contested amount from, and suspend the enforcement
thereof against, the applicable Properties, Lessor, each Holder, the Agent and
each Lender; (b) there shall not be imposed a Lien (other than Permitted Liens)
on any Property and no part of any Property nor any Rent shall be in any danger
of being sold, forfeited, lost or deferred; (c) at no time during the permitted
contest shall there be a risk of the imposition of criminal liability or
material civil liability on Lessor, any Holder, the Agent or any Lender for
failure to comply therewith; and (d) in the event that, at any time, there shall
be a material risk of extending the application of such item beyond the end of
the Term, then Lessee shall deliver to Lessor an Officer's

                                       11

<PAGE>

Certificate certifying as to the matters set forth in clauses (a), (b) and (c)
of this SECTION 13.1. Lessor, at Lessee's sole cost and expense, shall execute
and deliver to Lessee such authorizations and other documents as may reasonably
be required in connection with any such contest and, if reasonably requested by
Lessee, shall join as a party therein at Lessee's sole cost and expense.

                                   ARTICLE XIV

         14.1 PUBLIC LIABILITY AND WORKERS' COMPENSATION INSURANCE. During the
Term of each Property, Lessee shall procure and carry, at Lessee's sole cost and
expense, commercial general liability insurance for claims for injuries or death
sustained by persons or damage to property while on the Properties or the
premises where the Equipment is located and such other public liability
coverages as are then customarily carried by similarly situated companies
conducting business similar to that conducted by Lessee. Such insurance shall be
on terms and in amounts (and with deductibles and limitations on coverage) that
are (a) reasonably satisfactory to Lessor and the Agent and (b) no less
favorable than insurance maintained by Lessee with respect to similar properties
and equipment that it owns and are then carried by similarly situated companies
conducting business similar to that conducted by Lessee. The policies shall be
endorsed to name Lessor, the Agent, the Lenders and the Holders as additional
insureds. The policies shall also specifically provide that such policies shall
be considered primary insurance which shall apply to any loss or claim before
any contribution by any insurance which Lessor, any Holder, the Agent or any
Lender may have in force. Lessee shall, in the operation of the Properties,
comply with the applicable workers' compensation laws and protect Lessor, each
Holder, the Agent and each Lender against any liability under such laws.

         14.2 HAZARD AND OTHER INSURANCE.

                  (a) During the Term for each Property, Lessee shall keep, or
         cause to be kept, such Property insured against loss or damage by fire
         and all other risks and shall maintain builders' risk insurance during
         construction of any Improvements or Modifications in amounts not less
         than the replacement value from time to time of such Property and on
         terms that (i) are no less favorable than insurance covering other
         similar properties owned by Lessee and (ii) are then carried by
         similarly situated companies conducting business similar to that
         conducted by Lessee. Lessee shall not be required to maintain separate
         builder's insurance solely by reason of the Modifications to a Property
         if the cost of such Modifications will not exceed $25,000 in the
         aggregate. The policies shall be endorsed to name Lessor and the Agent
         (for itself and on behalf of the Lenders and the Holders), to the
         extent of their respective interests, as additional insureds and loss
         payees; PROVIDED, that so long as no Lease Event of Default has
         occurred and is continuing, any loss payable under the insurance
         policies required by this Section will be paid to Lessee.

                  (b) If, during the Term with respect to a Property the area in
         which such Property is located is designated a "flood-prone" area
         pursuant to the Flood Disaster Protection Act of 1973, or any
         amendments or supplements thereto, then Lessee shall comply with the
         National Flood Insurance Program as set forth in the Flood Disaster
         Protection Act of 1973. In addition, Lessee will fully comply with the
         requirements of the National Flood Insurance Act of 1968 and the Flood
         Disaster Protection Act of 1973, as each may be amended from

                                       12

<PAGE>

         time to time, and with any other Legal Requirement concerning flood
         insurance to the extent that it may apply to any such Property.

         14.3 COVERAGE.

                  (a) As of the date of this Lease and annually thereafter,
         Lessee shall furnish Lessor and the Agent with certificates prepared by
         the insurers or insurance broker of Lessee showing the insurance
         required under SECTIONS 14.1 AND 14.2 to be in effect, naming (except
         with respect to workers' compensation insurance) Lessor, the Agent,
         each Lender and each Holder as an additional insured on all insurance
         described in SECTION 14.1, and the Agent (for itself and on behalf of
         the Lenders and the Holders) as additional insured and loss payee on
         all insurance described in SECTION 14.2, and in each case evidencing
         the other requirements of this ARTICLE XIV. All such insurance shall be
         at the cost and expense of Lessee and provided by nationally
         recognized, financially sound insurance companies. Such certificates
         shall include a provision for thirty (30) days' advance written notice
         by the insurer to Lessor and the Agent in the event of cancellation or
         material alteration of such insurance. If a Lease Event of Default has
         occurred and is continuing and Lessor so requests, Lessee shall deliver
         to Lessor copies of all insurance policies required by SECTIONS 14.1
         AND 14.2.

                  (b) Lessee agrees that any insurance policy required by
         SECTIONS 14.1, 14.2(A) AND 14.2(B) shall include an appropriate
         provision that such policy will not be invalidated should Lessee waive,
         at any time, any or all rights of recovery against any party for losses
         covered by such policy or due to any breach of warranty, fraud, action,
         inaction or misrepresentation by Lessee or any Person acting on behalf
         of Lessee. Lessee hereby waives any and all such rights against the
         Lessor, the Holders, the Agent and the Lenders to the extent of
         payments made to any such Person under any such policy.

                  (c) Neither Lessor nor Lessee shall carry separate insurance
         concurrent in kind or form or contributing in the event of loss with
         any insurance required under this ARTICLE XIV, except that Lessor may
         carry separate liability insurance at Lessor's sole cost so long as (i)
         Lessee's insurance is designated as primary and in no event excess or
         contributory to any insurance Lessor may have in force which would
         apply to a loss covered under Lessee's policy and (ii) each such
         insurance policy will not cause Lessee's insurance required under this
         ARTICLE XIV to be subject to a coinsurance exception of any kind.

                  (d) Lessee shall pay as they become due all premiums for the
         insurance required by SECTION 14.1 AND SECTION 14.2, shall renew or
         replace each policy prior to the expiration date thereof, and shall
         otherwise maintain the coverage required by such Sections without any
         lapse in coverage.

         14.4 ADDITIONAL INSURANCE REQUIREMENTS. Without limiting the generality
of SECTIONS 14.1 through 14.3 above or any other provision of any Operative
Agreement, Lessee shall obtain any and all additional insurance policies with
regard to the Properties or otherwise with respect to the transactions
contemplated by the Operative Agreements, as requested from time to time by
Lessor.

                                   ARTICLE XV

         15.1 CASUALTY AND CONDEMNATION.

                  (a) Subject to the provisions of this ARTICLE XV and ARTICLE
         XVI (in the event Lessee delivers, or is obligated to deliver, a
         Termination Notice), and prior to the occurrence and continuation of a
         Lease Default or Lease Event of Default, Lessee shall be entitled to
         receive (and Lessor hereby irrevocably assigns to Lessee all of
         Lessor's right, title and interest in) any award, compensation or
         insurance proceeds under SECTIONS 14.2(A) OR (B) hereof to which Lessee
         or Lessor may become entitled by reason of their respective interests
         in a Property (i) if all or a portion of such Property is damaged or
         destroyed in whole or in part by a Casualty or (ii) if the use, access,
         occupancy, easement rights or title to such Property or any part
         thereof is the subject of a Condemnation; PROVIDED, HOWEVER, if a Lease
         Default or Lease Event of Default shall have occurred and be continuing
         such award, compensation or insurance proceeds shall be paid directly
         to Lessor or, if received by Lessee, shall be held in trust for Lessor,
         and shall be paid over by Lessee to Lessor and held in accordance with
         the terms of this paragraph (a). All amounts held by Lessor hereunder
         on account of any award, compensation or insurance proceeds either paid
         directly to Lessor or turned over to Lessor shall be held as security
         for the performance of Lessee's obligations hereunder.

                  (b) Lessee may appear in any proceeding or action to
         negotiate, prosecute, adjust or appeal any claim for any award,
         compensation or insurance payment on account of any such Casualty or
         Condemnation and shall pay all expenses thereof. At Lessee's reasonable
         request, and at Lessee's sole cost and expense, Lessor and the Agent
         shall participate in any such proceeding, action, negotiation,
         prosecution or adjustment. Lessor and Lessee agree that this Lease
         shall control the rights of Lessor and Lessee in and to any such award,
         compensation or insurance payment.

                  (c) If Lessee shall receive notice of a Casualty or a possible
         Condemnation of a Property or any interest therein where damage to the
         affected Property is estimated to equal or exceed ten percent (10%) of
         the Property Cost of such Property, Lessee shall give notice thereof to
         the Lessor and to the Agent promptly after the receipt of such notice.

                  (d) In the event of a Casualty or a Condemnation (regardless
         of whether notice thereof must be given pursuant to paragraph (c)),
         this Lease shall terminate with respect to the applicable Property in
         accordance with SECTION 16.1 if Lessee, within thirty (30) days after
         such occurrence, delivers to Lessor and the Agent a Termination Notice
         to such effect.

                  (e) If, pursuant to this SECTION 15.1, this Lease shall
         continue in full force and effect following a Casualty or Condemnation
         with respect to the affected Property, Lessee shall, at its sole cost
         and expense and using, if available, the proceeds of any award,
         compensation or insurance with respect to such Casualty or Condemnation
         (including, without limitation, any such award, compensation or
         insurance which has been received by the Agent and which should be
         turned over to Lessee pursuant to the terms of the Operative

                                       14

<PAGE>

         Agreements, and if not available or sufficient, using its own funds),
         promptly and diligently repair any damage to the applicable Property
         caused by such Casualty or Condemnation in conformity with the
         requirements of SECTIONS 10.1 AND 11.1, using the as-built plans and
         specifications or manufacturer's specifications for the applicable
         Improvements or Equipment (as modified to give effect to any subsequent
         Modifications, any Condemnation affecting the Property and all
         applicable Legal Requirements), so as to restore the applicable
         Property to substantially the same condition, operation, function and
         value as existed immediately prior to such Casualty or Condemnation. In
         such event, title to the applicable Property shall remain with Lessor.

                  (f) In no event shall a Casualty or Condemnation with respect
         to which this Lease remains in full force and effect under this SECTION
         15.1 affect Lessee's obligations to pay Rent pursuant to SECTION 3.1.

                  (g) Notwithstanding anything to the contrary set forth in
         SECTION 15.1(A) OR SECTION 15.1(E), if during the Term with respect to
         a Property a Casualty occurs with respect to such Property or Lessee
         receives notice of a Condemnation with respect to such Property, and
         following such Casualty or Condemnation, (i) the applicable Property
         cannot reasonably be restored, repaired or replaced on or before the
         180th day prior to the Expiration Date (if such Casualty or
         Condemnation occurs during the Term) to substantially the same
         condition as existed immediately prior to such Casualty or
         Condemnation, or (ii) on or before such day such Property is not in
         fact so restored, repaired or replaced, then Lessee shall be required
         to purchase such Property on the next Payment Date and pay Lessor the
         Termination Value for such Property, plus any and all Rent then due and
         owing, plus all other amounts then due and owing (including without
         limitation amounts described in clause FIRST of SECTION 22.2).

         15.2 ENVIRONMENTAL MATTERS. Promptly upon Lessee's actual knowledge of
the presence of Hazardous Substances in any portion of any Property (or in any
other property that is not subject to this Lease if Lessee has reason to believe
that such Hazardous Substances may be caused by an emission from or on, or a
condition on, any Property) in concentrations and conditions that constitute an
Environmental Violation and as to which, in the reasonable opinion of Lessee,
the cost to undertake any legally required response, clean up, remedial or other
action might result in a cost to Lessee or loss in the value of such Property of
more than $100,000, Lessee shall notify Lessor in writing of such condition. In
the event of any Environmental Violation (regardless of whether notice thereof
must be given to Lessor pursuant to the preceding sentence), Lessee shall, not
later than sixty (60) days after Lessee has actual knowledge of such
Environmental Violation, either deliver to Lessor a Termination Notice with
respect to the applicable Property or Properties pursuant to SECTION 16.1, if
applicable, or, at Lessee's sole cost and expense, promptly and diligently
undertake and complete any response, clean up, remedial or other action
necessary to remove, cleanup or remediate the Environmental Violation in
accordance with all Environmental Laws. If Lessee does not deliver a Termination
Notice with respect to such Property pursuant to SECTION 16.1, Lessee shall,
upon completion of remedial action by Lessee, cause to be prepared by a
reputable environmental consultant acceptable to Lessor a report describing the
Environmental Violation and the actions taken by Lessee (or its agents) in
response to such Environmental Violation, and a statement by the

                                       15

<PAGE>

consultant that the Environmental Violation has been remedied in full compliance
with applicable Environmental Law.

         15.3 NOTICE OF ENVIRONMENTAL MATTERS. Promptly, but in any event within
thirty (30) days from the date Lessee has actual knowledge thereof, Lessee shall
provide to Lessor written notice of any pending or threatened Environmental
Claim involving any Environmental Law or any Release on or in connection with
any Property. All such notices shall describe in reasonable detail the nature of
the claim, action or proceeding and Lessee's proposed response thereto. In
addition, Lessee shall provide to Lessor, within five (5) Business Days of
receipt, copies of all material written communications with any Governmental
Authority relating to any Environmental Law in connection with any Property.
Lessee shall also promptly provide such detailed reports of any such material
Environmental Claims as may reasonably be requested by Lessor.

                                   ARTICLE XVI

         16.1 TERMINATION UPON CERTAIN EVENTS. If any of the following occur:
(i) if the requirements of SECTION 15.1(C) are satisfied, or (ii) if the
requirements of SECTION 15.1(D) are satisfied and Lessee has determined pursuant
to such section that following the applicable Casualty or Condemnation this
Lease shall terminate with respect to the affected Property, or (iii) Lessee has
determined pursuant to the second sentence of SECTION 15.2 that, due to the
occurrence of an Environmental Violation, this Lease shall terminate with
respect to the affected Property, then Lessee shall be obligated to deliver,
within sixty (60) days of its receipt of notice of the applicable Condemnation
or the occurrence of the applicable Casualty or Environmental Violation, a
written notice to the Lessor in the form described in SECTION 16.2(A) (a
"Termination Notice") of the termination of this Lease with respect to the
applicable Property.

         16.2 PROCEDURES.

                  (a) A Termination Notice shall contain: (i) notice of
         termination of this Lease with respect to the affected Property on a
         Payment Date not more than sixty (60) days after Lessor's receipt of
         such Termination Notice (the "Termination Date"); and (ii) a binding
         and irrevocable agreement of Lessee to pay the Termination Value for
         the applicable Property, any and all Rent then due and owing and all
         other amounts then due and owing from Lessee under any of the Operative
         Agreements (including without limitation amounts described in clause
         FIRST of SECTION 22.2) and purchase such Property on such Termination
         Date.

                  (b) On each Termination Date, Lessee shall pay to Lessor the
         Termination Value for the applicable Property, any and all Rent then
         due and owing and all other amounts then due and owing from Lessee
         under any of the Operative Agreements (including without limitation
         amounts described in clause FIRST of SECTION 22.2), and Lessor shall
         convey such Property, or the remaining portion thereof, if any, to
         Lessee (or Lessee's designee), all in accordance with SECTION 19.1.

<PAGE>

                  (o) Any Operative Agreement shall cease to be in full force
         and effect; or

                  (p) Any material adverse change in (i) the business, condition
         (financial or otherwise) assets, liabilities or operations of Aviation

         of any Lien on any Property created by any of the Operative Agreements,

then, in any such event, Lessor may, in addition to the other rights and
remedies provided for in this ARTICLE XVII and in SECTION 18.1, terminate this
Lease by giving Lessee fifteen (15) days notice of such termination, and this
Lease shall terminate, and all rights of Lessee under this Lease shall cease.
Lessee shall, to the fullest extent permitted by law, pay as Supplemental Rent
all costs and expenses incurred by or on behalf of Lessor, including without
limitation reasonable fees and expenses of counsel, as a result of any Lease
Event of Default hereunder.

         17.2 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 17.1, Lessee shall, upon thirty (30) days written
notice, surrender to Lessor possession of the Properties. Lessor may enter upon
and repossess the Properties by such means as are available at law or in equity,
and may remove Lessee and all other Persons and any and all personal property
and Lessee's equipment and personalty and severable Modifications from the
Properties. Lessor shall have no liability by reason of any such entry,
repossession or removal performed in accordance with applicable law. Upon the
written demand of Lessor, Lessee shall return the Properties promptly to Lessor,
in the manner and condition required by, and otherwise in accordance with the
provisions of, SECTION 22.1(C) hereof.

         17.3 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 17.1, Lessor may, but shall be under no obligation to, relet any or all
of the Properties, for the account of 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 Lessor may determine, and
Lessor may collect, receive and retain the rents resulting from such reletting.
Lessor shall not be liable to Lessee for any failure to relet any Property or
for any failure to collect any rent due upon such reletting.

         17.4 DAMAGES. Neither (a) the termination of this Lease as to all or
any of the Properties pursuant to SECTION 17.1; (b) the repossession of all or
any of the Properties; nor (c) the failure of Lessor to relet all or any of the
Properties, the reletting of all or any portion thereof, nor the failure of
Lessor to collect or receive any rentals due upon any such reletting, shall
relieve Lessee of its liabilities 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 17.1, Lessee shall forthwith pay
to Lessor all Rent and other sums due and payable hereunder to and including the
date of such termination. Thereafter,

                                       19

<PAGE>

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 17.1 and until the end of the Term
hereof or what would have been the Term in the absence of such termination,
Lessee shall pay 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 Lessee hereunder if this Lease had not been terminated
pursuant to SECTION 17.1, provided that Lessee's obligation to make payments of
Basic Rent and Supplemental Rent under this SECTION 17.4 shall continue only so
long as Lessor shall not have received the amounts specified in SECTION 17.5.
The amount of Lessee's liabilities and obligations under this Lease shall not be
reduced or offset by any proceeds Lessor may receive from any reletting of any
Property, EXCEPT THAT the net proceeds, if any, which are actually received by
Lessor from reletting of any Property shall be offset against the final
liquidated damages amount specified in SECTION 17.5. In calculating the amount
of such net proceeds from reletting, there shall be deducted all of Lessor's,
any Holder's, the Agent's and any Lender's reasonable expenses in connection
therewith, including repossession costs, brokerage or sales commissions, fees
and expenses of counsel and any necessary repair or alteration costs and
expenses incurred in preparation for such reletting. To the extent Lessor
receives any damages pursuant to this SECTION 17.4, such amounts shall be
regarded as amounts paid on account of Rent. Lessee specifically acknowledges
and agrees that its obligations under this SECTION 17.4 shall be absolute and
unconditional under any and all circumstances and shall be paid or performed, as
the case may be, without notice or demand and without any abatement, reduction,
diminution, setoff, defense, counterclaim or recoupment whatsoever.

         17.5 FINAL LIQUIDATED DAMAGES. If a Lease Event of Default shall have
occurred and be continuing, whether or not this Lease shall have been terminated
pursuant to SECTION 17.1 and whether or not Lessor shall have collected any
current liquidated damages pursuant to SECTION 17.4, Lessor shall have the right
to recover, by demand to Lessee and at Lessor's election, and Lessee shall pay
to Lessor, as and for final liquidated damages, but exclusive of the indemnities
payable under SECTION 13 of the Participation Agreement, and in lieu of all
current liquidated damages beyond the date of such demand (it being agreed that
it would be impossible accurately to determine actual damages) the sum of (a)
the Termination Value for all Properties remaining under this Lease, PLUS (b)
all other amounts owing in respect of Rent, Supplemental Rent and other amounts
then due and payable under this Lease or any other Operative Agreement. It is
intended and agreed that the foregoing amount is and will be liquidated damages
and not a penalty. Upon payment of the amount specified pursuant to the first
sentence of this SECTION 17.5, Lessee shall be entitled to receive from Lessor,
either at Lessee's request or upon Lessor's election, in either case at Lessee's
cost, an assignment of Lessor's entire right, title and interest in and to the
Properties, the Improvements, Fixtures, Modifications and Equipment, in each
case in recordable form and otherwise in conformity with local custom and free
and clear of the Lien of this Lease (including the release of any memoranda of
Lease or the Lease Supplement recorded in connection therewith) and any Lessor
Liens. The Properties shall be conveyed to Lessee "AS IS" "WHERE IS" and in
their then present physical condition. If any statute or rule of law shall limit
the amount of such final liquidated damages to less than the amount agreed upon,
Lessor shall be entitled to the maximum amount allowable under such statute or
rule of law; PROVIDED, HOWEVER, Lessee shall not be entitled to receive an
assignment of Lessor's interest in the Properties, the Improvements, Fixtures,
Modifications or Equipment or

                                       20

<PAGE>

documents unless Lessee shall have paid in full the Termination Value and all
other amounts due and owing hereunder and under the other Operative Agreements.
Lessee specifically acknowledges and agrees that its obligations under this
SECTION 17.5 shall be absolute and unconditional under any and all circumstances
and shall be paid or performed, as the case may be, without notice or demand
(except as otherwise specifically provided herein) and without any abatement,
reduction, diminution, setoff, defense, counterclaim or recoupment whatsoever.

         17.6 WAIVER OF CERTAIN RIGHTS. If this Lease shall be terminated
pursuant to SECTION 17.1, 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 possession; (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 Lessor's rights or remedies under this ARTICLE XVII.

         17.7 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 17.1, Lessee shall upon Lessor's demand
immediately assign, transfer and set over to Lessor all of Lessee's right, title
and interest in and to each agreement executed by Lessee in connection with the
purchase, construction, development, use or operation of the Properties
(including, without limitation, all right, title and interest of Lessee with
respect to all warranty, performance, service and indemnity provisions), as and
to the extent that the same relate to the purchase, construction, use and
operation of the Properties.

         17.8 ENVIRONMENTAL COSTS. 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 17.1, Lessee shall pay directly to any third
party (or at Lessor's election, reimburse Lessor) for the cost of any
environmental testing or remediation work undertaken respecting any Property as
such testing or work is deemed appropriate in the reasonable judgment of Lessor.
Lessee shall pay all amounts referenced in the immediately preceding sentence
within ten (10) days of any request by Lessor for such payment.

         17.9 REMEDIES CUMULATIVE. The remedies herein provided shall be
cumulative and in addition to (and not in limitation of) any other remedies
available at law, equity or otherwise, including, without limitation, any
mortgage foreclosure remedies.

         17.10 NOTICE OF DEFAULT OR EVENT OF DEFAULT. Lessee shall promptly
notify the Lessor and the Agent if any Responsible Officer of Lessee has
received notice, or has actual knowledge, of any Default or Event of Default.

                                  ARTICLE XVIII

         18.1 LESSOR'S RIGHT TO CURE LESSEE'S LEASE DEFAULTS. Lessor, without
waiving or releasing any obligation or Lease Event of Default, may (but shall be
under no obligation to) remedy any Lease Event of Default for the account and at
the sole cost and expense of Lessee, including the failure by

                                       21

<PAGE>

Lessee to maintain the insurance required by ARTICLE XIV, and may, to the
fullest extent permitted by law, and notwithstanding any right of quiet
enjoyment in favor of Lessee, enter upon any Property, or real property owned or
leased by Lessee, take all such action thereon as may be necessary or
appropriate therefor, and inspect or copy any records relating to any Property
or the transactions contemplated hereby (and Lessee shall make available to
Lessor, for inspection thereof, any such records). No such entry shall be deemed
an eviction of any lessee. All reasonable out-of-pocket costs and expenses so
incurred (including without limitation reasonable fees and expenses of counsel),
together with interest thereon at the Overdue Rate from the date on which such
sums or expenses are paid by Lessor, shall be paid by Lessee to Lessor on
demand.

                                   ARTICLE XIX

         19.1 PROVISIONS RELATING TO LESSEE'S EXERCISE OF ITS PURCHASE OPTION.
Subject to SECTION 19.2, in connection with any termination of this Lease with
respect to any Property pursuant to the terms of SECTION 16.2, or in connection
with Lessee's exercise of its Purchase Option or its option to purchase all
Properties pursuant to SECTION 20.1, upon the date on which this Lease is to
terminate with respect to a Property or all of the Properties, and upon tender
by Lessee of the amounts set forth in SECTIONS 16.2(B) OR 20.1, as applicable,
Lessor shall execute and deliver to Lessee (or to Lessee's designee) at Lessee's
cost and expense an assignment of Lessor's entire interest in the applicable
Property, in each case in recordable form and otherwise in conformity with local
custom and free and clear of the Lien of this Lease and any Lessor Liens
attributable to Lessor but without any other warranties (of title or otherwise)
from the Lessor. The Lessor's interest in the applicable Property shall be
conveyed to Lessee "AS IS" "WHERE IS" and in then present physical condition. In
addition, Lessor shall, upon Lessee's request and at Lessee's expense, execute
and deliver any documents (including any appropriate releases of or amendments
to financing statements or recorded memoranda of this Lease) necessary to
release the Lien of this Lease on the applicable Property.

         19.2 NO TERMINATION WITH RESPECT TO LESS THAN ALL OF A PROPERTY. Lessee
shall not be entitled to exercise its Purchase Option separately with respect to
Property consisting of Land, Equipment and Improvements but shall be required to
exercise its Purchase Option with respect to an entire Property.

                                   ARTICLE XX

         20.1 PURCHASE PRIOR TO END OF TERM; PURCHASE OR SALE OPTION AT END OF
              TERM.

                  (a) PURCHASE OPTION PRIOR TO END OF TERM. Provided no Default
         or Event of Default shall have occurred and be continuing and provided
         that the Election Notice referred to in SECTION 20.1(B) has not been
         delivered, Lessee shall have the option, exercisable by giving the
         Agent and Lessor no more than one hundred twenty (120) days and no less
         than thirty (30) days written notice of Lessee's election to exercise
         such option, to purchase all (but not less than all) of the Properties
         on a Scheduled Interest Payment Date as identified in such written
         notice, at a price equal to the Termination Value for such Properties
         and all Rent then due and owing and all other amounts then due and
         owing (by the Lessee or the Construction Agent) under this Lease or
         under any other Operative Agreement (including

                                       22

<PAGE>

         without limitation amounts, if any, described in clause FIRST of
         SECTION 22.2) (which the parties do not intend to be a "bargain"
         purchase price); and, upon receipt of such amount, Lessor shall
         transfer to Lessee all Lessor's right, title and interest in and to
         such Properties in accordance with SECTION 19.1 as of the Business Day
         on which such purchase occurs; and the Expiration Date shall be deemed
         to have occurred on such date.

                  (b) PURCHASE OR SALE OPTION AT END OF TERM. Not less than 120
         days and no more than 180 days prior to the Expiration Date, Lessee may
         give Lessor and Agent irrevocable written notice (the "Election
         Notice") that Lessee is electing to exercise either (a) the option to
         purchase all, but not less than all, of the Properties on the
         Expiration Date (the "Purchase Option") or (b) the option to remarket
         all of the Properties and cause a sale of all of the Properties
         pursuant to the terms of SECTION 22.1 (the "Sale Option"), such sale to
         occur on the Expiration Date. If Lessee does not give an Election
         Notice indicating the Sale Option at least 120 days and not more than
         180 days prior to the Expiration Date, then Lessee shall be deemed to
         have elected the Purchase Option for the Expiration Date. Lessor shall
         have no obligation to sell any Property unless all of the Properties
         are sold on the Expiration Date. If Lessee shall (i) elect (or be
         deemed to elect) to exercise the Purchase Option, or (ii) elect to
         remarket all of the Properties pursuant to SECTION 22.1 and fail to
         deliver the environmental report required by SECTION 10.2 at the time
         specified in such Section, or (iii) elect to remarket all of the
         Properties pursuant to SECTION 22.1 and fail to cause all of the
         Properties to be sold in accordance with the terms of SECTION 22.1 on
         the Expiration Date on which such a sale of all of the Properties is
         required in connection with such election, then in each case, Lessee
         shall pay to Lessor on the Expiration Date or Payment Date an amount
         (the "Purchase Option Price") equal to the Termination Value for all
         the Properties (which the parties do not intend to be a "bargain"
         purchase) plus all Rent and other amounts then due and payable under
         this Lease or under any other Operative Agreement (including without
         limitation the amounts described in clause FIRST of SECTION 22.2), and,
         upon receipt of such amount, Lessor shall transfer to Lessee all of
         Lessor's right, title and interest in and to the Properties in
         accordance with SECTION 19.1. Lessee may not elect the Sale Option, and
         Lessor shall have no obligation to sell any Property pursuant to
         SECTION 22.1, if a Lease Event of Default has occurred and is
         continuing on the date of the Election Notice or the Sale Date.

         20.2 ACCOUNTING CHANGES. Although neither Lessor, the Agent, NMS, nor
any Lender or Holder makes any representation or warranty with respect to the
Lessee's accounting treatment of this transaction, Lessee represents that a
material incentive for Lessee to enter into this Lease is the advice of the
Lessee's independent auditors that this Lease may be treated as an operating
lease for financial accounting purposes under the applicable rules and
interpretations of the Financial Accounting Standards Board and/or the
Securities Exchange Commission (the "Lease Accounting Rules") in effect as of
the date of this Lease. In the event that Lessee's independent auditors shall
determine that any subsequent change in the Lease Accounting Rules will preclude
the Lessee (or raise a substantial question as to whether the Lessee is
precluded) from continuing to account for this Lease as an operating lease with
substantially the same financial accounting benefits as before the change in
Lease Accounting Rules, then the Lessee shall so notify the Lessor and the Agent
in writing of such determination by its auditors; and Lessee may elect (by
delivery of irrevocable written notice of such election to the Lessor and the
Agent) to purchase all of the Properties or to cause all of the

                                       23

<PAGE>

Properties to be transferred to a third party transferee designated by Lessee
(such purchase or transfer to be consummated on a date (the "Accounting Change
Transfer Date") specified by Lessee in such notice and in any event within sixty
(60) days after the date of such notice). On the Accounting Change Transfer Date
(whether the Properties are to be purchased by Lessee or transferred to a third
party), Lessee shall pay to Lessor an amount equal to the Termination Value for
all the Properties (which the parties do not intend to be a "bargain" purchase)
plus all Rent and other amounts then due and payable under this Lease or under
any other Operative Agreement (including without limitation the amounts
described in clause FIRST of SECTION 22.2), and, upon receipt of such amount,
Lessor shall transfer to Lessee (or to the third party designated by Lessee) all
of Lessor's right, title and interest in and to the Properties in accordance
with SECTION 19.1 and the Expiration Date shall be deemed to have occurred on
the date of such transfer (without giving Lessee the right to remarket
Properties pursuant to Section 22.1).

         22.1 SALE PROCEDURE.

                  (a) During the Marketing Period, Lessee, on behalf of the
         Lessor, shall obtain bids for the cash purchase of all of the
         Properties in connection with a sale to one or more purchasers (other
         than Lessee or any Subsidiary or Affiliate of Lessee) to be consummated
         on the Expiration Date for the highest price available, shall notify
         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 any Property and shall provide Lessor with such additional
         information about the bids and the bid solicitation procedure as Lessor
         may reasonably request from time to time. Lessor may reject any and all
         bids and may assume sole responsibility for obtaining bids by giving
         Lessee written notice to that effect; PROVIDED, HOWEVER, that
         notwithstanding the foregoing, Lessor may not reject the highest bids
         for the Properties submitted by the Lessee if (i) such bids, in the
         aggregate, are greater than or equal to the sum of the Limited Recourse
         Amount for all of the Properties, plus all reasonable costs and
         expenses referred to in clause FIRST of SECTION 22.2 and represent bona
         fide offers from one or more third party purchasers, and (ii) prior to
         Lessor's acceptance of any such bid, Lessee has delivered to the Agent
         cash collateral in an amount not less than the anticipated Deficiency
         Balance (as defined in SECTION 22.1(B) below) as determined by the
         Agent. If the price which a prospective purchaser or purchasers shall
         have offered to pay for the Properties is less than the sum of the
         Limited Recourse Amount plus all reasonable costs and expenses referred
         to in clause FIRST of SECTION 22.2, Lessor may elect to retain the
         Properties by giving Lessee prior written notice of Lessor's election
         to retain the Properties, and upon receipt of such notice, Lessee shall
         surrender the Properties to Lessor pursuant to SECTION 10.1. Unless
         Lessor shall have elected to retain the Properties pursuant to the
         preceding sentence, Lessee shall arrange for Lessor to sell the
         Properties free and clear of the Lien of this Lease and any Lessor
         Liens attributable to it, without recourse or warranty (of

                                       24

<PAGE>

         title or otherwise), for cash on the last day of the Marketing Period
         (such date being hereafter referred to as the "Sale Date") to the
         purchaser or purchasers identified by Lessee or Lessor, as the case may
         be; PROVIDED, HOWEVER, solely as to Lessor or the Trust Company, in its
         individual capacity, any Lessor Lien shall not constitute a Lessor Lien
         so long as Lessor or the Trust Company, in its individual capacity, is
         diligently contesting such Lessor Lien by appropriate proceedings in
         good faith; and PROVIDED FURTHER that Lessor shall have no obligation
         to sell any Property if a Lease Event of Default has occurred and is
         continuing on the Date of the Election Notice or the Sale Date. Lessee
         shall surrender the Property so sold or subject to such documents to
         each purchaser in the condition specified in SECTION 10.1. Lessee shall
         not take or fail to take any action which would have the effect of
         unreasonably discouraging bona fide third party bids for any Property.
         Lessor shall have no obligation to sell any Property on the Sale Date
         unless all of the Properties are sold (and Lessor has received full
         payment therefor in cash in the amount required pursuant to this
         SECTION 22.1) on the Sale Date. If all of the Properties are not either
         (i) sold on the Sale Date in accordance with the terms of this SECTION
         22.1, or (ii) retained by the Lessor pursuant to an affirmative
         election made by the Lessor pursuant to the third sentence of this
         SECTION 22.1(A), then the Lessee shall be obligated to pay the Lessor
         on the Sale Date an amount equal to the Termination Value for all of
         the Properties (plus all Rent and other amounts then due and payable
         under this Lease and any other Operative Agreements) in accordance with
         the terms of SECTION 20.2.

                  (b) If the Properties are sold on the Sale Date to one or more
         third party purchasers in accordance with the terms of SECTION 22.1(A)
         and the aggregate purchase price paid for the Properties minus the sum
         of all costs and expenses referred to in clause FIRST of SECTION 22.2
         is less than the sum of the aggregate Termination Values for all of the
         Properties plus all Rent and other amounts then due and payable under
         this Lease and under any other Operative Agreements (hereinafter such
         difference shall be referred to as the "Deficiency Balance"), then the
         Lessee hereby unconditionally promises to pay to the Lessor on the Sale
         Date the lesser of (i) the Deficiency Balance, or (ii) the Maximum
         Residual Guarantee Amount for all of the Properties. If the Properties
         are retained by the Lessor pursuant to an affirmative election made by
         the Lessor pursuant to the third sentence of SECTION 22.1(A), then the
         Lessee hereby unconditionally promises to pay to the Lessor on the Sale
         Date an amount equal to the Maximum Residual Guarantee Amount for all
         of the Properties.

                  (c) In the event that the Properties are either sold to one or
         more third party purchasers on the Sale Date or retained by the Lessor
         in connection with an affirmative election made by the Lessor pursuant
         to the third sentence of SECTION 22.1(A), then in either case on the
         Sale Date the Lessee shall provide Lessor or such third party
         purchasers with (i) all permits, certificates of occupancy,
         governmental licenses and authorizations necessary to use and operate
         such Property for its intended purposes, (ii) such easements, licenses,
         rights-of-way and other rights and privileges in the nature of an
         easement as are reasonably necessary or desirable in connection with
         the use, repair, access to or maintenance of such Property for its
         intended purpose or otherwise as the Lessor shall reasonably request,
         and (iii) a services agreement covering such services as Lessor or such
         third party purchaser may

                                       25

<PAGE>

         request in order to use and operate a Property for its intended
         purposes at such rates (not in excess of arm's-length fair market
         rates) as shall be acceptable to Lessee and Lessor or such third party
         purchaser. All assignments, licenses, easements, agreements and other
         deliveries required by clauses (i) and (ii) of this paragraph (c) shall
         be in form reasonably satisfactory to the Lessor or such third party
         purchaser, as applicable, and shall be fully assignable (including both
         primary assignments and assignments given in the nature of security)
         without payment of any fee, cost or other charge.

         22.2 APPLICATION OF PROCEEDS OF SALE. The Lessor shall apply the
proceeds of sale of any Property in the following order of priority:

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

                  (b) SECOND, so long as the Participation Agreement, the Credit
         Agreement or the Trust Agreement is in effect and any Loan, Holder
         Advance or any other amount is owing to the Lenders, the Holders or any
         other Person under any Operative Agreement, to the Agent to be applied
         pursuant to inter-creditor provisions between the Lenders and the
         Holders contained in the Operative Agreements; and

                  (c) THIRD, to the Lessee.

         22.3 INDEMNITY FOR EXCESSIVE WEAR. If the proceeds of the sale
described in SECTION 22.1 with respect to the Properties, less all expenses
incurred by Lessor in connection with such sale, shall be less than the Limited
Recourse Amount with respect to the Properties, and at the time of such sale it
shall have been reasonably determined (pursuant to the Appraisal Procedure) that
the Fair Market Sales Value of the Properties, shall have been impaired by
greater than expected wear and tear during the term of the Lease, Lessee shall
pay to Lessor within ten (10) days after receipt of Lessor's written statement
(i) the amount of such excess wear and tear determined by the Appraisal
Procedure or (ii) the amount of the Net Sale Proceeds Shortfall, whichever
amount is less.

         22.4 APPRAISAL PROCEDURE. For determining the Fair Market Sales Value
of any Property or any other amount which may, pursuant to any provision of any
Operative Agreement, be determined by an appraisal procedure, Lessor and Lessee
shall use the following procedure (the "Appraisal Procedure"). Lessor and Lessee
shall endeavor to reach a mutual agreement as to such amount for a period of ten
(10) days from commencement of the Appraisal Procedure under the applicable
section of the Lease, and if they cannot agree within ten (10) days, then two
qualified appraisers, one chosen by Lessee and one chosen by Lessor, shall
mutually 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 Lessee and 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
(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
appraiser most different from the

                                       26

<PAGE>

average of the other two shall be discarded and such average shall be binding on
Lessor and Lessee; PROVIDED that if the highest appraisal and the lowest
appraisal are equidistant from the third appraisal, the third appraisal shall be
binding on Lessor and Lessee. The fees and expenses of the appraiser appointed
by Lessee shall be paid by Lessee; the fees and expenses of the appraiser
appointed by Lessor shall be paid by Lessor (such fees and expenses not being
indemnified pursuant to SECTION 13 of the Participation Agreement); and the fees
and expenses of the third appraiser shall be divided equally between Lessee and
Lessor.

         22.5 CERTAIN OBLIGATIONS CONTINUE. During the Marketing Period, the
obligation of Lessee to pay Rent with respect to the Properties (including the
installment of Basic Rent due on the Expiration Date) shall continue
undiminished until payment in full to Lessor of the sale proceeds, if any, the
Maximum Residual Guarantee Amount, the amount due under SECTION 22.3, if any,
and all other amounts due to Lessor with respect to all Properties. Lessor shall
have the right, but shall be under no duty, to solicit bids, to inquire into the
efforts of Lessee to obtain bids or otherwise to take action in connection with
any such sale, other than as expressly provided in this ARTICLE XXII.

                                  ARTICLE XXIII

         23.1 HOLDING OVER. If Lessee shall for any reason remain in possession
of a Property after the expiration or earlier termination of this Lease as to
such Property (unless such Property is conveyed to Lessee), such possession
shall be as a tenancy at sufferance during which time Lessee shall continue to
pay Supplemental Rent that would be payable by Lessee hereunder were the Lease
then in full force and effect with respect to the Property and Lessee shall
continue to pay Basic Rent at 110% of the Basic Rent that would otherwise be due
and payable at such time. Such Basic Rent shall be payable from time to time
upon demand by Lessor and such additional 10% amount shall be applied by the
Lessor to the payment of the Loans pursuant to the Credit Agreement and the
Holder Advances pursuant to the Trust Agreement pro rata between the Loans and
the Holder Advances. During any period of tenancy at sufferance, Lessee shall,
subject to the first sentence of this paragraph, be obligated to perform and
observe all of the terms, covenants and conditions of this Lease, but shall have
no rights hereunder other than the right, to the extent given by law to tenants
at sufferance, to continue their occupancy and use of such Property. Nothing
contained in this ARTICLE XXIII shall constitute the consent, express or
implied, of Lessor to the holding over of Lessee after the expiration or earlier
termination of this Lease as to any Property (unless such Property is conveyed
to Lessee) and nothing contained herein shall be read or construed as preventing
Lessor from maintaining a suit for possession of such Property or exercising any
other remedy available to Lessor at law or in equity.

                                  ARTICLE XXIV

         24.1 RISK OF LOSS. During the Term, unless Lessee shall not be in
actual possession of the Property in question solely by reason of Lessor's
exercise of its remedies of dispossession under ARTICLE XVII, the risk of loss
or decrease in the enjoyment and beneficial use of such Property as a result of
the damage or destruction thereof by fire, the elements, casualties, thefts,
riots, wars or otherwise is assumed by Lessee, and Lessor shall in no event be
answerable or accountable therefor.

                                   ARTICLE XXV

         25.1 ASSIGNMENT.

                  (a) Lessee may not assign, mortgage, pledge or encumber this
         Lease or any of its rights or obligations hereunder in whole or in part
         to any Person without the prior written consent of the Agent, the
         Lessor and the Lenders, with such consent to be given or withheld in
         the sole discretion of each such party.

                  (b) No such assignment or other relinquishment of possession
         to any Property shall in any way discharge or diminish any of the
         obligations of Lessee to Lessor hereunder and Lessee shall remain
         directly and primarily liable under this Lease.

         25.2 SUBLEASES.

                  (a) Except as set forth in this Section 25.2(a), Lessee may
         not sublet any Property or portion thereof without first obtaining the
         prior written consent of the Lessor and the Agent, which consent may be
         given or withheld in the sole discretion of each such party.

                  (b) Lessee may, without the consent of Lessor or the Agent,
         sublet a Property only if:

                           (i) Lessee remains fully liable for all obligations
                  (including without limitation all Rent and other obligations
                  with respect to such subleased Properties and any other
                  Properties) under this Lease, each Lease Supplement and the
                  other Operative Agreements;

                           (ii) Such sublease is in writing and is expressly
                  subject and subordinate to the rights of the Lessor, the
                  Agent, the Lenders and the Holders under this Lease, the
                  Security Agreement, each Mortgage Instrument and all other
                  Operative Agreements; and

                           (iii) Such sublease is on commercially reasonable
                  terms and at market rates, and has a term that does not extend
                  past the Expiration Date, and such Property is at all times
                  used for the purposes set forth in this paragraph and in the
                  definition of "Property."

                  (c) No sublease or other relinquishment of possession to any
         Property shall in any way discharge or diminish any of Lessee's
         obligations to Lessor hereunder and Lessee shall remain directly and
         primarily liable under this Lease as to the Property so sublet.

                                       28

<PAGE>

                  (d) Each insurance policy carried by Lessee pursuant to
         ARTICLE XIV hereof shall be endorsed to name each sublessee under any
         such sublease as an additional insured. Prior to the effectiveness of
         any such sublease, Lessee shall deliver a copy thereof to the Lessor
         and the Agent.

                  (e) Promptly but in any event within five (5) days following
         the execution and delivery of any sublease permitted by this ARTICLE
         XXV, Lessee shall notify Lessor and the Agent of the execution of such
         sublease. As of the date of each Lease Supplement, Lessee shall lease
         the respective Properties described in such Lease Supplement from
         Lessor, and (without limiting the generality of SECTIONS 25.2(A) - (D))
         any existing tenant respecting such Property shall automatically be
         deemed to be a subtenant of Lessee and not a tenant of Lessor.

                                  ARTICLE XXVI

         26.1 NO WAIVER. No failure by Lessor or Lessee to insist upon the
strict performance of any term hereof or to exercise any right, power or remedy
upon a default hereunder, and no acceptance of full or partial payment of Rent
during the continuance of any such default, shall constitute a waiver of any
such default or of any such term. To the fullest extent permitted by law, no
waiver of any default shall affect or alter this Lease, and this Lease shall
continue in full force and effect with respect to any other then existing or
subsequent default.

                                  ARTICLE XXVII

         27.1 ACCEPTANCE OF SURRENDER. No surrender to Lessor of this Lease or
of all or any portion of any Property or of any part of any thereof or of any
interest therein shall be valid or effective unless agreed to and accepted in
writing by Lessor and the Agent, and no act by Lessor or the Agent or any
representative or agent of Lessor or the Agent, other than a written acceptance,
shall constitute an acceptance of any such surrender.

         27.2 NO MERGER OF TITLE. There shall be no merger of this Lease or of
the leasehold estate created hereby by reason of the fact that the same Person
may acquire, own or hold, directly or indirectly, in whole or in part, (a) this
Lease or the leasehold estate created hereby or any interest in this Lease or
such leasehold estate, (b) any right, title or interest in any Property, (c) any
Notes, or (d) a beneficial interest in Lessor.

                                 ARTICLE XXVIII

         28.1 REPORTING COVENANTS. The Lessee covenants and agrees that, until
the obligations of the Lessee, the Construction Agent and the Guarantors under
the Operative Agreements have been paid and satisfied in full and the Operative
Agreements have been terminated in accordance with the terms thereof, unless the
Lessor and the Majority Lenders shall otherwise give their prior written consent
thereto:

         practices to permit preparation of consolidated and consolidating Fin-

                  to any fiscal quarter is delayed for any reason and Lessee has

                  connection with such Financial Statements has been made in
                  accordance with generally accepted auditing standards.
                  Notwithstanding the foregoing, in the event (1) the filing of
                  the Lessee's annual report with the SEC with respect to any

                  delay by the due date for the reports required for such Fiscal
                  Year under this CLAUSE (II) and (2) the Lessee shall deliver
                  either the required reports or interim good faith estimates of
                  the information required to be reported under this CLAUSE (II)
                  within one hundred (100) days after the end of each Fiscal
                  Year, upon delivery of such required reports or interim
                  estimates within such period the Lessee shall be deemed to
                  have complied with the requirements of this CLAUSE (II) with
                  respect to such Fiscal Year PROVIDED THAT the Lessee delivers

                           (iii) OFFICER'S CERTIFICATE. Together with each
                  delivery of any Financial Statement pursuant to this SECTION
                  28.1(A), (A) an Officer's Certificate on behalf of the Lessee

                  Person signatory thereto has reviewed the terms of the
                  Operative Agreements, and has made, or caused to be made under
                  his/her supervision, a review in reasonable detail of the
                  transactions and financial condition of the Lessee and its
                  Subsidiaries during the accounting period covered by such
                  Financial Statements, that such review has not disclosed the
                  existence during or at the end of such accounting period, and
                  that such Person does not have knowledge of the existence as
                  at the date of such Officer's Certificate, of any condition or
                  event which constitutes an Event of Default or Default, or, if
                  any such condition or event existed or exists, specifying the
                  nature and period of existence thereof and what action the
                  Lessee or any Subsidiary has taken, is taking and proposes to
                  take with respect thereto; and (B) a certificate (the
                  "Compliance Certificate"), signed by the Lessee's chief
                  financial officer, setting forth calculations (with such
                  specificity as the Lessor or the Agent may reasonably request)
                  for the period then ended which demonstrate compliance, when
                  applicable, with the provisions of SECTION 28.4.

                           (iv) ACCOUNTANT'S STATEMENT AND PRIVITY LETTER.
                  Together with each delivery of the Financial Statements
                  referred to in SECTION 28.1(A)(I), a written statement, in
                  form and substance satisfactory to the Lessor and the Agent,
                  of the firm of independent certified public accountants
                  giving the report thereon (A) stating that their audit
                  examination has included a review of the terms of this
                  Agreement as it relates to accounting matters, (B) stating
                  whether, in connection with their audit examination, any
                  condition or event which constitutes an Event of Default or
                  Default has come to

                                       31

<PAGE>

                  their attention, and if such condition or event has come to
                  their attention, specifying the nature and period of existence
                  thereof; PROVIDED THAT such accountants shall not be liable by
                  reason of any failure to obtain knowledge of any such
                  condition or event that would not be disclosed in the course
                  of their audit examination, and (C) stating that based on
                  their audit examination nothing has come to their attention
                  which causes them to believe that the information contained in
                  either or both of the certificates delivered therewith
                  pursuant to SECTION 28.1(A)(III) (as the information contained
                  in such certificates relates to financial covenants set forth
                  in SECTION 28.4) is not correct or that the matters set forth
                  in the Compliance Certificate delivered therewith pursuant to
                  SECTION 28.1(A)(III)(B) for the applicable Fiscal Year are not
                  stated in accordance with the terms of this Agreement. The

                  of the management letter or any similar report delivered to
                  the Lessee or any Subsidiary or to any officer or employee
                  thereof by such accountants in connection with such Financial
                  Statements and (2) a letter in substantially the form of

                  Financial Statements audited by such accountants and delivered
                  to the Agent the Lessor, the Lenders and the Holders pursuant
                  to SECTION 28.1(A)(II). The Agent or the Lessor may, with the
                  written consent of the Lessee (which consent shall not be
                  unreasonably withheld or delayed), communicate directly with

         directly, by assumption or by Accommodation Obligation, with respect to
         any lease, whether an Operating Lease or a Capital Lease, of any Assets
         (whether real or personal property or mixed property) which it (a) sold
         or transferred or is to sell or transfer to any other Person, or (b)

notwithstanding, all claims against and liabilities of Lessee or Lessor arising
from events commencing prior to the expiration or earlier termination of this
Lease shall survive such expiration or earlier termination. If any provision of
this Lease shall be held to be unenforceable in any jurisdiction, such

Supplement nor any provision hereof may be amended, waived, discharged or

otherwise affect the meaning hereof.

         30.5 COUNTERPARTS. This Lease may be executed in any number of

together constitute one and the same instrument.

         30.6 GOVERNING LAW. THIS LEASE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF FLORIDA WITHOUT REGARD TO ANY OTHERWISE
APPLICABLE PRINCIPLES OF CONFLICT OF LAWS, EXCEPT TO THE EXTENT THE LAWS OF THE

PERFECTION, FORECLOSURE AND ENFORCEMENT OF LIENS ON SUCH PROPERTY.

         30.7 CALCULATION OF RENT. All calculation of Rent payable hereunder

<PAGE>

Lease Supplement (in substantially the form of EXHIBIT B attached hereto)
regarding each Property promptly after the acquisition thereof in the local

and as required under applicable law to sufficiently evidence this Lease or any
such Lease Supplement in the applicable real estate filing records.

         30.9 ALLOCATIONS BETWEEN THE LENDERS AND THE HOLDERS. Notwithstanding
any other term or provision of this Lease to the contrary, the allocations of
the proceeds of the Properties and any and all other Rent and other amounts
received hereunder shall be subject to the inter-creditor provisions between the

agreed among the Lenders and the Holders from time to time).

         30.10 LIMITATIONS ON RECOURSE. Notwithstanding anything contained in
this Lease to the contrary, Lessee agrees to look solely to Lessor's estate and
interest in the Properties for the collection of any judgment requiring the
payment of money by Lessor in the event of liability by Lessor, and no other
property or assets of Lessor or any shareholder, owner or partner (direct or
indirect) in or of Lessor, or any director, officer, employee, beneficiary,
Affiliate of any of the foregoing shall be subject to levy, execution or other
enforcement procedure for the satisfaction of the remedies of Lessee under or
with respect to this Lease, the relationship of Lessor and Lessee hereunder or
Lessee's use of the Properties or any other liability of Lessor to Lessee,
EXCEPT to the extent expressly provided in SECTION 10.2(A) or 14.11(B) of the

constitutes chattel paper, as such term is defined in the Uniform Commercial

Lease may be created through the transfer or possession of any counterpart other
than the Original Executed Counterpart.

         30.13 MORTGAGE GRANT AND REMEDIES. Without limiting any other remedies
set forth in this Lease, in the event that a court of competent jurisdiction
rules that this Lease constitutes a mortgage, deed of trust, security deed or
other secured financing, as is the intent of the parties, then the Lessor and
the Lessee agree that the Lessee hereby grants, bargains, sells, conveys,
mortgages, and grants a security interest in each Property to Lessor WITH POWER
OF SALE to secure the payment of all sums due and owing by Lessee or the
Construction Agent hereunder or under any other Operative Agreement, and that,
upon the occurrence of any Event of Default, the Lessor shall have the power and
authority, to the extent provided by law or the Operative Agreements, after
prior notice and lapse of such time as may be required by law, to foreclose its
interest (or cause such interest to be foreclosed) in all or any part of any
Property, to appoint or obtain the appointment of a receiver for

                                       46

<PAGE>

all or any part of the Property, and to exercise any other right or remedy that
may be available under applicable law to the holder of a mortgage, deed of
trust, security deed or other secured financing.

         30.14 EXERCISE OF LESSOR RIGHTS. The Lessee hereby acknowledges and
agrees that the rights and powers of the Lessor under this Lease have been
collaterally assigned to the Agent pursuant to the terms of the Security
Agreement and the other Operative Agreements, and that the Lessor has encumbered
the Properties by various Mortgage Instruments made by the Lessor in favor of
the Agent, all as security for certain indebtedness and obligations described
therein of the Lessor to the Agent, the Lenders and the Holders under the
Operative Agreements. Lessee hereby consents to said assignment and said
Mortgage Instruments in favor of the Agent and further acknowledges and agrees
as follows:

                  (a) In the event that a court of competent jurisdiction rules
         that this Lease constitutes a mortgage, deed of trust, security deed or
         other secured financing as is the intent of the parties, then the
         Lessor and the Lessee agree that the Lessor's collateral assignment of
         this Lease to the Agent shall be deemed to be a collateral assignment
         of such mortgage, deed of trust, security deed or other secured
         financing, and the Agent as such collateral assignee shall be entitled
         to exercise any and all rights and remedies of the Lessor set forth
         herein during the existence of any Event of Default, including without
         limitation the Lessor's rights to obtain a receiver, to obtain
         possession of the Properties and the rents and revenues thereof, to
         foreclose this Lease, to sell the Lessee's interest in the Properties,
         and to exercise any other rights or remedies that may then be available
         to the Lessor under applicable law on account of such Event of Default.

                  (b) Lessee's interest in the Properties is junior and
         subordinate to the lien of any Mortgage Instruments made by the Lessor
         in favor of the Agent against the respective Properties from time to
         time in connection with the Operative Agreements; provided, however,
         that for so long as no Event of Default shall have occurred and be
         continuing, (i) the Agent shall not disturb Lessee's possession of the
         Properties through any foreclosure or other remedial action against the
         Properties under any Mortgage Instrument, and (ii) if Lessor's interest
         in any Property shall be transferred to any Person other than the
         Lessee as the result of the Agent's foreclosure or other remedial
         action under any Mortgage Instrument, the Lessee shall (upon request of
         the Agent) attorn to such transferee and recognize the transferee as
         the Lessee's landlord under this Lease.

                  (c) During the existence of an Event of Default, the Agent as
         holder of the Mortgage Instruments and as collateral assignee of this
         Lease may exercise any and all rights and remedies that may then be
         available under applicable law to the Agent in either or both
         capacities, whether exercised singly, successively or concurrently.
         Without limiting the generality of the foregoing, the Agent as
         collateral assignee may enforce the Lessee's payment obligations under
         this Lease (regardless of whether this Lease shall be deemed a
         mortgage, deed of trust, security deed or other secured financing) even
         if Lessee's interest and estate in any Property under this Lease shall
         have been extinguished or forfeited under applicable law through the
         foreclosure or other enforcement of any Mortgage Instrument.

         SECTION 4. RATIFICATION. Except as specifically modified hereby, the
terms and provisions of the Lease and the Operative Agreements are hereby
ratified and confirmed and remain in full force and effect.

         SECTION 5. ORIGINAL LEASE SUPPLEMENT. The single executed original of
this Lease Supplement marked "THIS COUNTERPART IS THE ORIGINAL EXECUTED
COUNTERPART" on the signature page thereof and containing the receipt of the
Agent therefor on or following the signature page thereof shall be the original
executed counterpart of this Lease Supplement (the "Original Executed
Counterpart"). To the extent that this Lease Supplement constitutes chattel
paper, as such term is defined in the Uniform Commercial Code as in effect in
any applicable jurisdiction, no security interest in this Lease Supplement may
be created through the transfer or possession of any counterpart other than the
Original Executed Counterpart.

         SECTION 6. GOVERNING LAW. AS TO MATTERS RELATING TO THE CREATION,
PERFECTION, AND FORECLOSURE OF LIENS, AND ENFORCEMENT OF RIGHTS AND REMEDIES
AGAINST THE LEASED PROPERTY, THIS LEASE SUPPLEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF ________________ WITHOUT
REGARD TO ANY OTHERWISE APPLICABLE PRINCIPLES OF CONFLICT OF LAWS. THIS LEASE
SUPPLEMENT SHALL IN ALL OTHER RESPECTS BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF FLORIDA.

         SECTION 7. MORTGAGE GRANT AND REMEDIES.  Without limiting any other
remedies set forth in the Lease, in the event that a court of competent
jurisdiction rules that the Lease constitutes a mortgage, deed of trust,
security deed or other secured financing as is the intent of the parties, then
the Lessor and the Lessee agree that the Lessee hereby grants, bargains, sells,
conveys, mortgages, and grants a security interest in each Property to Lessor
WITH POWER OF SALE to secure the payment of all sums due and owing by Lessee or
the Construction Agent hereunder or under any other Operative Agreement, and
that, upon the occurrence of any Event of Default, the Lessor shall have the
power and authority, to the extent provided by law or the Operative Agreements,
after prior notice and lapse of such time as may be required by law, to
foreclose its interest (or cause such interest to be foreclosed) in all or any
part of any Property, to appoint or obtain the appointment of a receiver for all
or any part of the Property, and to exercise any other right or remedy that may
be available under applicable law to the holder of a mortgage, deed of trust,
security deed or other secured financing.

         SECTION 8. EXERCISE OF LESSOR RIGHTS. The Lessee hereby acknowledges
and agrees that the rights and powers of the Lessor under the Lease have been
collaterally assigned to the Agent pursuant to the terms of the Security
Agreement and the other Operative Agreements, and that the Lessor has encumbered
the Properties by various Mortgage Instruments made by the Lessor in favor of
the Agent, all as security for certain indebtedness and obligations described
therein of the Lessor to the Agent, the Lenders and the Holders under the
Operative Agreements. Lessee hereby consents to said assignment and said
Mortgage Instruments in favor of the Agent and further acknowledges and agrees
as follows:

                  (i) In the event that a court of competent jurisdiction rules
         that the Lease constitutes a mortgage, deed of trust, security deed or
         other secured financing as is the intent of the parties, then the
         Lessor and the Lessee agree that the Lessor's collateral assignment of
         the Lease to the Agent shall be deemed to be a collateral assignment of
         such mortgage, deed of

                                       50

<PAGE>

         trust, security deed or other secured financing, and the Agent as such
         collateral assignee shall be entitled to exercise any and all rights
         and remedies of the Lessor set forth herein during the existence of any
         Event of Default, including without limitation the Lessor's rights to
         obtain a receiver, to obtain possession of the Properties and the rents
         and revenues thereof, to foreclose the Lease, to sell the Lessee's
         interest in the Properties, and to exercise any other rights or
         remedies that may then be available to the Lessor under applicable law
         on account of such Event of Default.

                  (ii) Lessee's interest in the Properties is junior and
         subordinate to the lien of any Mortgage Instruments made by the Lessor
         in favor of the Agent against the respective Properties from time to
         time in connection with the Operative Agreements; provided, however,
         that for so long as no Lease Event of Default shall have occurred and
         be continuing, (i) except to the extent permitted by SECTION 5.1 of the
         Lease, the Agent shall not disturb Lessee's possession of the
         Properties through any foreclosure or other remedial action against the
         Properties under any Mortgage Instrument, and (ii) if Lessor's interest
         in any Property shall be transferred to any Person other than the
         Lessee as the result of the Agent's foreclosure or other remedial
         action under any Mortgage Instrument, the Lessee shall (upon request of
         the Agent) attorn to such transferee and recognize the transferee as
         the Lessee's landlord under the Lease.

                  (iii) During the existence of an Event of Default, the Agent
         as holder of the Mortgage Instruments and as collateral assignee of the
         Lease may exercise any and all rights and remedies that may then be
         available under applicable law to the Agent in either or both
         capacities, whether exercised singly, successively or concurrently.
         Without limiting the generality of the foregoing, the Agent as
         collateral assignee may enforce the Lessee's payment obligations under
         the Lease (regardless of whether the Lease shall be deemed a mortgage,
         deed of trust, security deed or other secured financing) even if
         Lessee's interest and estate in any Property under this Lease shall
         have been extinguished or forfeited under applicable law through the
         foreclosure or other enforcement of any Mortgage Instrument.

         SECTION 9. COUNTERPART EXECUTION. This Lease Supplement may be executed
in any number of counterparts and by each of the parties hereto in separate
counterparts, all such counterparts together constituting but one and the same
instrument.

<PAGE>
                               GUARANTY AGREEMENT
                             (SERIES A OBLIGATIONS)

         THIS GUARANTY AGREEMENT (SERIES A OBLIGATIONS) (the "Guaranty
Agreement" or the "Guaranty"), dated as of December 17, 1998 is made by AVIATION
SALES COMPANY, a Delaware corporation ("Aviation Sales" or the "Lessee") and THE
OTHER GUARANTORS SIGNATORY HERETO (collectively with Aviation Sales, the
"Guarantors") to NATIONSBANK, NATIONAL ASSOCIATION, as Administrative Agent (the
"Agent") for the ratable benefit of the Series A Lenders (as defined in the
Participation Agreement referred to below).

                              W I T N E S S E T H:

         WHEREAS, the Agent and First Security Bank, N.A. (the "Borrower") have
entered into the Credit Agreement dated as of the date hereof (as from time to
time amended, modified, restated or supplemented, the "Credit Agreement"); and
Aviation Sales, as Construction Agent (the "Construction Agent"), Aviation
Sales, as Lessee (the "Lessee"), the Borrower, the Holders party thereto from
time to time, the Lenders party thereto from time to time, and the Agent have
entered into the Participation Agreement dated as of the date hereof (as from
time to time amended, modified, restated or supplemented, the "Participation
Agreement"); and

         WHEREAS, pursuant to the Credit Agreement, the Participation Agreement
and certain other Operative Agreements (as defined in the Participation
Agreement), the Lenders with respect to the Series A Loans (the "Series A
Lenders") will extend a credit facility to the Borrower in the aggregate
principal amount of up to the aggregate Commitments for Series A Loans under the
Credit Agreement; and

         WHEREAS, the proceeds of the Series A Loans will be used by the
Borrower to acquire and improve certain Properties which will be leased by the
Borrower to the Lessee as set forth in the Operative Agreements; and

         WHEREAS, it is condition to the obligations of the Series A Loans under
the Credit Agreement that the Guarantors execute and deliver this Guaranty
Agreement; and

         WHEREAS, Aviation Sales is the Lessee of the Properties and the other
Guarantors are direct or indirect subsidiaries of Aviation Sales, all of which
will materially benefit from (a) the Series A Lenders' extension of the credit
facility and making of Series A Loans to the Borrower, and (b) the Borrower's
acquisition and improvement of the Properties and its lease of the Properties to
the Lessee; and the Guarantors are willing to enter into this Guaranty to
provide an inducement for the Series A Lenders to extend the credit facility and
make Series A Loans to the Borrower;

         NOW, THEREFORE, as required under the Operative Agreements and in order
to induce the Series A Lenders to extend the credit facility and to make Series
A Loans, each Guarantor agrees as follows:

                                        2


<PAGE>



         1. DEFINITIONS. All capitalized terms not otherwise defined herein
shall have the meanings ascribed to such terms in the Credit Agreement or (if
not defined in the Credit Agreement) in the Participation Agreement.

         2. GUARANTY. Each Guarantor hereby, effective immediately following the
Completion of a Property (the "Completion Date"), unconditionally, absolutely,
continually and irrevocably guarantees to the Agent and the Series A Lenders the
payment in full of the Borrower's Liabilities (as defined below). For all
purposes of this Guaranty Agreement, "Borrower's Liabilities" means: the
Borrower's prompt payment in full, when due or declared due and at all such
times, of all Series A Loans and all other amounts pursuant to the terms of the
Credit Agreement, the Series A Notes and all other Operative Agreements
heretofore, now or at any time or times hereafter owing, arising, due or payable
from the Borrower to the Series A Lenders (or to the Agent on behalf of the
Series A Lenders), including without limitation all principal and interest on
any Series A Loans, and any fees or expenses (including, but not limited to,
attorneys' fees and expenses). Each Guarantor's obligations to the Agent and the
Series A Lenders under this Guaranty Agreement are hereinafter collectively
referred to as the "Guarantors' Obligations".

         Each Guarantor agrees that, as of the Completion Date it shall be
directly and primarily liable for the Borrower's Liabilities.

         3. PAYMENT. If the Borrower shall, on or after the Completion Date
default in payment of any Borrower's Liabilities, when and as the same shall
become due (and such default is not cured within the applicable grace period, if
any), whether according to the terms of the Credit Agreement, any Series A Note
or any other Operative Agreement, by acceleration, or otherwise, or upon the
occurrence of any other Event of Default that has not been cured or waived, then
each Guarantor, upon demand thereof by the Agent, or its successors or assigns,
will AS OF THE DATE OF THE AGENT'S DEMAND fully pay to the Agent (for the
benefit of the Series A Lenders), an amount equal to all of the Guarantors'
Obligations then due and owing.

         4. UNCONDITIONAL OBLIGATIONS. This is a guaranty of payment and not of
collection. The Guarantors' Obligations under this Guaranty Agreement shall be
absolute and unconditional irrespective of the validity, legality or
enforceability of the Credit Agreement, any Series A Note or any other Operative
Agreement, or any other guaranty of the Borrower's Liabilities, and shall not be
affected by any action taken under the Credit Agreement, any Series A Note or
any other Operative Agreement, any other guaranty of the Borrower's Liabilities,
or any other agreement between the Borrower and the Agent, any Series A Lender
or any other Person, in the exercise of any right or power therein conferred, or
by any failure or omission to enforce any right conferred thereby, or by any
waiver of any covenant or condition therein provided, or by any acceleration of
the maturity of any of the Borrower's Liabilities, or by the release or other
disposal of any security for any of the Borrower's Liabilities, or by the
dissolution of the Lessee or the combination or consolidation of the Lessee or
the Borrower into or with another entity or any transfer or disposition of any
assets of the Lessee or the Borrower, or by any extension or renewal of the
Credit Agreement, any Series A Note or any other Operative Agreement, in whole
or in part, or by any modification, alteration, amendment or addition of or to
the Credit Agreement, any Series A Note or any other Operative Agreement, any
other guaranty of the Borrower's Liabilities, or any other agreement between the
Borrower and the

                                        3


<PAGE>



Agent, any Series A Lender or any other Person, or by any defense to or
avoidance or rejection (by a bankruptcy trustee or otherwise) of the Credit
Agreement, any Series A Note or any other Operative Agreement in any bankruptcy
or similar proceeding, or by any other circumstance whatsoever (with or without
notice to or knowledge of any Guarantor) which may or might in any manner or to
any extent vary the risks of any Guarantor, or might otherwise constitute a
legal or equitable discharge of a surety or guarantor; it being the purpose and
intent of the parties hereto that this Guaranty Agreement and the Guarantors'
Obligations hereunder shall be absolute and unconditional under any and all
circumstances and shall not be discharged except by payment as herein provided.
Without limiting the generality of the foregoing, each Guarantor acknowledges
and agrees that (a) the Guarantors' Obligations are absolute and separate from
the Borrower's obligations under the Credit Agreement, any Series A Note or any
other Operative Agreement, (b) the Guarantors' Obligations hereunder shall not
be reduced, limited or otherwise affected if the Credit Agreement, any Series A
Note or any other Operative Agreement is avoided, rejected or limited as an
executory contract in a bankruptcy or similar proceeding, and (c) for the
purpose of defining the Guarantor's Obligations, hereunder, the amount of the
Borrower's Liabilities shall include without limitation all principal and
interest on any Series A Loan and any other amount which is due or may become
due under the Credit Agreement, any Series A Note or any other Operative
Agreement, including without limitation any principal, interest or other amount
that would have been payable at any time but for the avoidance, rejection or
limitation of any Operative Agreement in a bankruptcy or similar proceeding.

         5. CURRENCY AND FUNDS OF PAYMENT. Each Guarantor hereby guarantees that
the Guarantor's Obligations will be paid in lawful currency of the United States
of America and in immediately available funds, regardless of any law, regulation
or decree now or hereafter in effect that might in any manner affect the
Borrower's Liabilities, or the rights of the Agent (or any Series A Lender) with
respect thereto as against the Borrower, or cause or permit to be invoked any
alteration in the time, amount or manner of payment by the Lessee of any or all
of the Borrower's Liabilities.

         6. EVENTS OF DEFAULT. In the event that (a) any Guarantor shall file a
petition to take advantage of any insolvency statute; (b) any Guarantor shall
commence or suffer to exist a proceeding for the appointment of a receiver,
trustee, liquidator or conservator of itself or of the whole or substantially
all of its property; (c) any Guarantor shall file a petition or answer seeking
reorganization or arrangement or similar relief under the Federal bankruptcy
laws or any other applicable law or statute of the United States of America or
any state or similar law of any other country; (d) a court of competent
jurisdiction shall enter an order, judgment or decree appointing a custodian,
receiver, trustee, liquidator or conservator of any Guarantor or of the whole or
substantially all of its properties, or approve a petition filed against any
Guarantor seeking reorganization or arrangement or similar relief under the
Federal bankruptcy laws or any other applicable law or statute of the United
States of America or any state or similar law of any other country, or if, under
the provisions of any other law for the relief or aid of debtors, a court of
competent jurisdiction shall assume custody or control of any Guarantor or of
the whole or substantially all of its properties and such order, judgment,
decree, approval or assumption remains unstayed or undismissed for a period of
sixty (60) consecutive days; (e) there is commenced against any Guarantor any
proceeding or petition seeking reorganization, arrangement or similar relief
under the Federal bankruptcy laws or any other applicable law or statute of the
United States of America or any state, which proceeding or petition

                                        4


<PAGE>



remains unstayed or undismissed for a period of sixty (60) consecutive days; (f)
there shall occur Event of Default (as defined in the Participation Agreement);
(g) any default shall occur in the payment of amounts due hereunder; or (h) any
other default shall occur hereunder which remains uncured or unwaived for a
period of thirty (30) days after receipt of written notice thereof from the
Agent or the Lessor thereof (each of the foregoing an "Event of Default"
hereunder); then notwithstanding any collateral that the Agent or any Lender may
possess from the Borrower or any Guarantor or any other guarantor of the
Borrower's Liabilities, or any other party, at the Agent's election and without
notice thereof or demand therefor, so long as such Event of Default shall be
continuing, the Guarantor's Obligations shall immediately become due and
payable.

         7. SUITS. Each Guarantor shall from time to time on or after the
Completion Date pay to the Agent (on behalf of the Series A Lenders), on demand,
at the Agent's place of business set forth in the Credit Agreement, the
Guarantor's Obligations as they become or are declared due, and in the event
such payment is not made forthwith, the Agent may proceed to suit against any
Guarantor or all the Guarantors. At the Agent's election, one or more and
successive or concurrent suits may be brought hereon by the Agent against the
Guarantors, whether or not suit has been commenced against the Borrower, any
other guarantor of the Borrower's Liabilities, or any other Person and whether
or not the Agent has taken or failed to take any other action to collect all or
any portion of the Borrower's Liabilities.

         8. SET-OFF AND WAIVER. Each Guarantor waives any right to assert
against the Agent or any Series A Lender as a defense, counterclaim, set-off or
cross claim, any defense (legal or equitable) or other claim which such
Guarantor may now or at any time hereafter have against the Lessee, the
Borrower, the Agent, any Lender, or any Holder, without waiving any additional
defenses, set-offs, counterclaims or other claims otherwise available to such
Guarantor. If at any time hereafter the Agent or any Series A Lender employs
counsel for advice or other representation to enforce the Guarantor's
Obligations that arise out of an Event of Default, then, in any of the foregoing
events, all of the attorneys' fees arising from such services and all expenses,
costs and charges in any way or respect arising in connection therewith or
relating thereto shall be obligations of the Guarantors and shall be paid by the
Guarantors to the Agent (or such Series A Lender), on demand.

         9. WAIVER; SUBROGATION.

         (a) Each Guarantor hereby waives notice of the following events or
occurrences: (i) the Agent's (or any Lender's) acceptance of this Guaranty
Agreement; (ii) any Series A Lender's heretofore, now or from time to time
hereafter, making any advances to the Borrower whether pursuant to the Credit
Agreement or any Series A Note, or any amendments, modifications, restatements
or supplements thereto, or replacements or extensions thereof; (iii) the
Borrower, the Agent or any Lender heretofore, now or at any time hereafter,
obtaining, amending, substituting for, releasing, waiving or modifying the
Credit Agreement, any Series A Note or any other Operative Agreements; (iv)
presentment, demand, notices of default, non-payment, partial payment and
protest; (v) the Agent (or any Lender) heretofore, now or at any time hereafter,
granting to the Borrower (or any other party liable to the Lessor on account of
the Borrower's Liabilities) any indulgence or extensions of time of payment of
the Borrower's Liabilities; and (vi) the Borrower heretofore, now

                                        5


<PAGE>



or at any time hereafter, accepting from the Agent (or any Lender) or any other
person, any partial payment or payments on account of the Borrower's Liabilities
or any collateral securing the payment thereof or the Agent (or any Lender)
settling, subordinating, compromising, discharging or releasing the same. Each
Guarantor agrees that on or after the Completion Date the Agent (or any Lender)
may at any time thereafter do any or all of the foregoing in such manner, upon
such terms and at such times as the Agent (or any Lender), in its sole and
absolute discretion, deems advisable, without in any way or respect impairing,
affecting, reducing or releasing any Guarantor from the Guarantor's Obligations,
and each Guarantor hereby consents to each and all of the foregoing events or
occurrences.

         (b) Each Guarantor hereby agrees that payment or performance by such
Guarantor of the Guarantor's Obligations under this Guaranty Agreement may be
enforced by the Agent upon demand by the Agent to such Guarantor without the
Agent being required, each Guarantor expressly waiving any right it may have to
require the Agent, to (i) prosecute collection or seek to enforce or resort to
any remedies against the Lessee, the Borrower or the other Guarantors or any
other guarantor of the Lessee's Liabilities, IT BEING EXPRESSLY UNDERSTOOD,
ACKNOWLEDGED AND AGREED TO BY EACH GUARANTOR THAT DEMAND UNDER THIS GUARANTY
AGREEMENT MAY BE MADE BY THE AGENT, AND THE PROVISIONS HEREOF ENFORCED BY THE
AGENT, EFFECTIVE AS OF THE FIRST DATE ON OR AFTER THE COMPLETION DATE ANY EVENT
OF DEFAULT OCCURS AND IS CONTINUING, or (ii) seek to enforce or resort to any
remedies with respect to any security interests, Liens or encumbrances granted
to the Agent by the Borrower or any other Person on account of the Lessee's
Liabilities or any guaranty thereof. The Agent shall not have any obligation to
protect, secure or insure any of the foregoing security interests, Liens or
encumbrances on the properties or interests in properties subject thereto. The
Guarantor's Obligations shall in no way be impaired, affected, reduced, or
released by reason of the Agent's failure or delay to do or take any of the
acts, actions or things described in this Guaranty Agreement including, without
limiting the generality of the foregoing, those acts, actions and things
described in this SECTION 10.

         (c) Each Guarantor further agrees with respect to this Guaranty
Agreement that, until the Borrower's Liabilities have been paid in full and the
Lenders and the Holders have no further obligation to make any Loan or Holder
Advance, no Guarantor shall have any right of subrogation, reimbursement or
indemnity, nor any right of recourse to security for the Borrower's Liabilities.
This waiver is expressly intended to prevent the existence of any claim in
respect to such reimbursement by any Guarantor against the estate of Borrower
within the meaning of Section 101 of the Bankruptcy Code, and to prevent each
Guarantor from constituting a creditor of Borrower in respect of such
reimbursement within the meaning of Section 547(b) of the Bankruptcy Code in the
event of a subsequent case involving the Lessee.

         (d) Any claim or claims that the Agent may at any time hereafter have
against any Guarantor under this Guaranty Agreement may be asserted by the Agent
by written notice directed to such Guarantor.

         10. EFFECTIVENESS; ENFORCEABILITY. This Guaranty Agreement shall be
effective as of the Completion Date and shall continue in full force and effect
until the Borrower's Liabilities are fully

                                        6

paid and the Credit Agreement, each Series A Note and the Participation
Agreement have terminated in accordance with their respective terms. The Agent
shall give the Guarantors written notice of such termination at the address set
forth in Section 17 below. This Guaranty Agreement shall be binding upon each
Guarantor and its successors and assigns and shall inure to the benefit of the
Agent, each Series A Lender, and their respective successors and assigns.
Notwithstanding the foregoing, no Guarantor may, without the prior written
consent of the Agent, assign any rights, powers, duties or obligations
hereunder.

         11. REPRESENTATIONS AND WARRANTIES. Each Guarantor warrants and
represents to the Agent and each Series A Lender that such Guarantor is duly
authorized to execute, deliver and perform this Guaranty Agreement, that this
Guaranty Agreement is legal, valid, binding and enforceable against such
Guarantor in accordance with its terms except as enforceability may be limited
by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of creditors' rights generally and by general equitable
principles; and that such Guarantor's execution, delivery and performance of
this Guaranty Agreement do not violate or constitute a breach of its certificate
of incorporation or other documents of corporate governance or any agreement to
which such Guarantor is a party, or any applicable laws, in each case, which
violation or breach could reasonably be expected to have a material adverse
effect on the business, operations or condition (financial or otherwise) of such
Guarantor.

         12. INCORPORATION OF COVENANTS. Reference is made to Article XXVIII of
the Lease, and the "Incorporated Covenants" (as defined therein). Each Guarantor
agrees with the Lessor that, effective as of the date hereof (whether or not the
Basic Term has commenced with respect to any Property), the Incorporated
Covenants (and all other relevant provisions of the Existing Aviation Sales
Credit Agreement related thereto) are hereby incorporated by reference into this
Guaranty Agreement to the same extent and with the same effect as if set forth
fully herein and shall inure to the benefit of the Lessor, without giving effect
to any waiver, amendment, modification or replacement of the Existing Aviation
Sales Credit Agreement or any term or provision of the Incorporated Covenants
occurring subsequent to the date of this Guaranty, except to the extent any such
waiver or modification (or any covenants contained in any New Facility) are
approved as Incorporated Covenants pursuant to Section 28.1(a) of the Lease.
Without limiting the generality of the foregoing, from and after the date hereof
(whether or not the Basic Term has commenced with respect to any Property), to
the extent that the Incorporated Covenants require Aviation Sales or any of its
Subsidiaries to deliver any financial statement, certificate, notice, report, or
other document or information to the Existing Credit Agent (or any other agent
under the applicable credit facility), each Guarantor shall simultaneously
deliver a copy of such financial statement, certificate, notice, report,
document or information to the Agent, each Lender and (upon Lessor's request)
the Lessor.

         13. EXPENSES. Each Guarantor agrees to be liable for the payment of all
fees and expenses, including attorney's fees, incurred by the Agent or any
Series A Lender in connection with the enforcement of this Guaranty Agreement.

         14. REINSTATEMENT. Each Guarantor agrees that this Guaranty Agreement
shall continue to be effective or be reinstated, as the case may be, at any time
payment received by the Lessor under

of counterparts, each of which shall be deemed to be an original as against any
party whose signature appears thereon, and all of which shall constitute one and

each Series A Lender that: (a) such Guarantor has adequate means to obtain from
Borrower, on a continuing basis, information concerning Lessee or Borrower and
Lessee's or Borrower's financial condition and affairs and has full and complete
access to Lessee's or Borrower's books and records; (b) such Guarantor is not
relying on the Agent, any Lender, or any of their respective employees, agents
or other representatives, to provide such information, now or in the future; (c)
such Guarantor is executing this Guaranty Agreement freely and deliberately, and
understands the obligations and financial risk undertaken by providing this
Guaranty; (d) such Guarantor has relied solely on its own independent
investigation, appraisal and analysis of Lessee and Borrower and Lessee's and
Borrower's financial condition and affairs in deciding to provide this Guaranty
and is fully aware of the same; and (e) such Guarantor has not depended or
relied on the Agent, any Lender, or any of their respective employees, agents or
representatives, for any information whatsoever concerning Lessee or Borrower or
Lessee's or Borrower's financial condition and affairs or other matters material
to such Guarantor's decision to provide this Guaranty or for any counseling,
guidance, or special consideration or any promise therefor with respect to such
decision. Each Guarantor agrees that neither the Agent nor any Lender has any
duty or responsibility whatsoever, now or in the future, to provide to such
Guarantor any information concerning Lessee or the Borrower or Lessee's or the
Borrower's financial condition and affairs, other than as expressly provided
herein, and that, if such Guarantor receives any such information from the
Agent, any Lender, or any of their respective employees, agents or other
representatives, such Guarantor will independently verify the information and
will not rely on the Agent, any Lender, or any of their respective employees,
agents or other representatives, with respect to such information.

         17. TERMINATION. This Guaranty Agreement and all obligations of the
Guarantors hereunder shall terminate without delivery of any instrument or
performance of any act by any party on the date when all of the Borrower's
Liabilities have been fully paid and the Credit Agreement, each Series A Note
and the Participation Agreement have terminated in accordance with their
respective terms.

                               GUARANTY AGREEMENT

         THIS GUARANTY AGREEMENT (the "Guaranty Agreement" or the "Guaranty"),
dated as of December 17, 1998, is made by THE GUARANTORS SIGNATORY HERETO (the
"Guarantors"), to FIRST SECURITY BANK, NATIONAL ASSOCIATION, as Owner Trustee
under the Aviation Sales Trust 1998-1, as Lessor under the Lease (defined below)
(the "Lessor").

                              W I T N E S S E T H:

         WHEREAS, the Lessor and Aviation Sales Company, a Delaware corporation
("Aviation Sales" or the "Lessee") have entered into that certain Lease
Agreement dated as of the date hereof (as from time to time amended, modified or
supplemented, the "Lease"), pursuant to which the Lessor has leased or will
lease certain Properties to the Lessee, subject to the terms and conditions of
the Lease; and

         WHEREAS, the Guarantors are direct or indirect subsidiaries of the
Lessee and will derive direct and indirect benefits from the Lessee entering
into the Lease; and

         WHEREAS, it is a condition to the Lessor entering into the Lease that
the Guarantors execute and deliver this Guaranty, and that the Guarantors
guaranty the obligations of the Lessee as hereinafter set forth;

         NOW, THEREFORE, as required under the Lease and in order to induce the
Lessor to lease the Properties to the Lessee thereunder, the Guarantors agree as
follows:

         1. DEFINITIONS. All capitalized terms not otherwise defined herein
shall have the meanings ascribed to such terms in the Lease or (if not defined
in the Lease) in the Participation Agreement dated as of the date hereof among
Aviation Sales, as Construction Agent, the Lessee, the Lessor, the Holders party
thereto, the Lenders party thereto, and NationsBank, National Association, as
Administrative Agent (such agreement, as from time to time amended, modified or
supplemented, being referred to as the "Participation Agreement").

         2. GUARANTY. Each Guarantor hereby unconditionally, absolutely,
continually and irrevocably guarantees to the Lessor the payment and performance
in full of the Lessee's Liabilities (as defined below). For all purposes of this
Guaranty Agreement, "Lessee's Liabilities" means: (a) the Lessee's prompt
payment in full, when due or declared due and at all such times, of all Rent and
all other amounts pursuant to the terms of the Lease, the Lease Supplements, the
Participation Agreement, the Agency Agreement, and all other Operative
Agreements executed in connection with the Lease or the Agency Agreement
heretofore, now or at any time or times hereafter owing, arising, due or payable
from the Lessee to the Lessor, including without limitation any payment or
amount owed by the Lessee in its capacity as Lessee or as Construction Agent,
and including without limitation Basic Rent, Supplemental Rent, any purchase
price, Deficiency Balance or Maximum Residual Guaranty Amount with respect to
any Property, and any fees or expenses (including, but not limited to,
attorneys' fees and expenses); and (b) the Lessee's prompt, full and faithful
performance,

                                        2


<PAGE>



observance and discharge of each and every agreement, undertaking, covenant and
provision to be performed, observed or discharged by the Lessee under the Lease,
the Lease Supplements, the Participation Agreement, the Agency Agreement and all
other Operative Agreements executed in connection with the Lease or the Agency
Agreement, including without limitation any obligation of the Lessee in its
capacity as Lessee or as Construction Agent. Each Guarantor's obligations to the
Lessor under this Guaranty Agreement are hereinafter collectively referred to as
the "Guarantor's Obligations."

         Each Guarantor agrees that it is directly and primarily liable for the
Lessee's Liabilities.

         3. PAYMENT. If the Lessee shall default in payment or performance of
any Lessee's Liabilities, when and as the same shall become due (and such is not
cured within the applicable grace period, if any), whether according to the
terms of the Lease, any Lease Supplement, the Participation Agreement, the
Agency Agreement or any other Operative Agreement, by acceleration, or
otherwise, or upon the occurrence of any other Event of Default that has not
been cured or waived, then each Guarantor, upon demand thereof by the Lessor or
its successors or assigns, will AS OF THE DATE OF THE LESSOR'S DEMAND fully pay
to the Lessor an amount equal to all of the Guarantors' Obligations then due and
owing.

         4. UNCONDITIONAL OBLIGATIONS. This is a guaranty of payment and not of
collection. The Guarantors' Obligations under this Guaranty Agreement shall be
absolute and unconditional irrespective of the validity, legality or
enforceability of the Lease, any Lease Supplement, the Participation Agreement,
the Agency Agreement or any other Operative Agreement, or any other guaranty of
the Lessee's Liabilities, and shall not be affected by any action taken under
the Lease, any Lease Supplement, the Participation Agreement, or any other
Operative Agreement, any other guaranty of the Lessee's Liabilities, or any
other agreement between the Lessor and the Lessee or any other person, in the
exercise of any right or power therein conferred, or by any failure or omission
to enforce any right conferred thereby, or by any waiver of any covenant or
condition therein provided, or by any acceleration of the maturity of any of the
Lessee's Liabilities, or by the release or other disposal of any security for
any of the Lessee's Liabilities, or by the dissolution of the Lessee or the
combination or consolidation of the Lessee into or with another entity or any
transfer or disposition of any assets of the Lessee or by any extension or
renewal of the Lease, any Lease Supplement, the Participation Agreement, the
Agency Agreement or any other Operative Agreement, in whole or in part, or by
any modification, alteration, amendment or addition of or to the Lease, any
Lease Supplement, the Participation Agreement or any other Operative Agreement,
any other guaranty of the Lessee's Liabilities, or any other agreement between
the Lessor and the Lessee or any other Person, or by any defense to or avoidance
or rejection (by a bankruptcy trustee or otherwise) of the Lease, any Lease
Supplement, the Participation Agreement, the Agency Agreement or any other
Operative Agreement in any bankruptcy or similar proceeding, or by any other
circumstance whatsoever (with or without notice to or knowledge of any
Guarantor) which may or might in any manner or to any extent vary the risks of
any Guarantor, or might otherwise constitute a legal or equitable discharge of a
surety or guarantor; it being the purpose and intent of the parties hereto that
this Guaranty Agreement and the Lessee's Obligations hereunder shall be absolute
and unconditional under any and all circumstances and shall not be discharged
except by payment as herein provided. Without limiting the generality of the
foregoing, each Guarantor acknowledges and agrees that (a)

Agreement, including without limitation any Basic Rent, Supplemental Rent or
other amount that would have been payable at any time but for the avoidance,
rejection or limitation of the Lease, any Lease Supplement or other Operative
Agreement in a bankruptcy or similar proceeding.

         5. CURRENCY AND FUNDS OF PAYMENT. Each Guarantor hereby guarantees that
the Guarantors' Obligations will be paid in lawful currency of the United States
of America and in immediately available funds, regardless of any law, regulation
or decree now or hereafter in effect that might in any manner affect the
Lessee's Liabilities, or the rights of the Lessor with respect thereto as
against the Lessee, or cause or permit to be invoked any alteration in the time,
amount or manner of payment by the Lessee of any or all of the Lessee's
Liabilities.

         6. EVENTS OF DEFAULT. In the event that (a) any Guarantor shall file a
petition to take advantage of any insolvency statute; (b) any Guarantor shall
commence or suffer to exist a proceeding for the appointment of a receiver,
trustee, liquidator or conservator of itself or of the whole or substantially
all of its property; (c) any Guarantor shall file a petition or answer seeking

Federal bankruptcy laws or any other applicable law or statute of the United
States of America or any state or similar law of any other country, or if, under
the provisions of any other law for the relief or aid of debtors, a court of

decree, approval or assumption remains unstayed or undismissed for a period of
sixty (60) consecutive days; (e) there is commenced against any Guarantor any

notwithstanding any collateral that the Lessor may possess from Lessee or any
Guarantor or any other guarantor of the Lessee's Liabilities, or any other
party, at the Lessor's election and without notice thereof or demand therefor,
so long as such Event of Default shall be continuing, the Guarantors'
Obligations shall immediately become due and payable.

                                        4


<PAGE>



         7. SUITS. The Guarantors shall pay to the Lessor, on demand, at the
Lessor's place of business set forth in the Lease, the Guarantors' Obligations
as they become or are declared due, and in the event such payment is not made
forthwith, the Lessor may proceed to suit against any Guarantor. At the Lessor's
election, one or more and successive or concurrent suits may be brought hereon
by the Lessor against any Guarantor, whether or not suit has been commenced
against the Lessee, any other Guarantor, any other guarantor of the Lessee's
Liabilities, or any other Person and whether or not the Lessor has taken or
failed to take any other action to collect all or any portion of the Lessee's
Liabilities.

         8. SET-OFF AND WAIVER. Each Guarantor waives any right to assert
against the Lessor as a defense, counterclaim, set-off or cross claim, any
defense (legal or equitable) or other claim which such Guarantor may now or at
any time hereafter have against the Lessee or the Lessor, without waiving any
additional defenses, set-offs, counterclaims or other claims otherwise available
to such Guarantor. If at any time hereafter the Lessor employs counsel for
advice or other representation to enforce the Guarantors' Obligations that
arise out of an Event of Default, then, in any of the foregoing events, all of
the attorneys' fees arising from such services and all expenses, costs and
charges in any way or respect arising in connection therewith or relating
thereto shall be obligations of the Guarantors and shall be paid by the
Guarantors to the Lessor, on demand.

         9.       WAIVER; SUBROGATION.

         (a) Each Guarantor hereby waives notice of the following events or
occurrences: (i) the Lessor's acceptance of this Guaranty Agreement; (ii) the
Lessor's heretofore, now or from time to time hereafter making any advances to
the Construction Agent or leasing any Property to the Lessee, whether pursuant
to the Lease or any amendments, modifications, restatements or supplements
thereto, or replacements or extensions thereof; (iii) the Lessor or the Lessee
heretofore, now or at any time hereafter, obtaining, amending, substituting for,
releasing, waiving or modifying the Lease, the Agency Agreement or any other
Operative Agreements; (iv) presentment, demand, notices of default, non-payment,
partial payment and protest; (v) the Lessor heretofore, now or at any time
hereafter granting to the Lessee (or any other party liable to the Lessor on
account of the Lessee's Liabilities) any indulgence or extensions of time of
payment of the Lessee's Liabilities; and (vi) the Lessor heretofore, now or at
any time hereafter accepting from the Lessee or any other person, any partial
payment or payments on account of the Lessee's Liabilities or any collateral
securing the payment thereof or the Lessor settling, subordinating,
compromising, discharging or releasing the same. Each Guarantor agrees that the
Lessor may heretofore, now or at any time hereafter do any or all of the
foregoing in such manner, upon such terms and at such times as the Lessor, in
its sole and absolute discretion, deems advisable, without in any way or respect
impairing, affecting, reducing or releasing any Guarantor from the Guarantors'
Obligations, and each Guarantor hereby consents to each and all of the foregoing
events or occurrences.

         (b) Each Guarantor hereby agrees that payment or performance by such
Guarantor of the Guarantors' Obligations under this Guaranty Agreement may be
enforced by the Lessor upon demand by the Lessor to such Guarantor without the
Lessor being required, each Guarantor expressly waiving any right it may have to
require the Lessor, to (i) prosecute collection or seek to enforce or resort to
any remedies against the Lessee, any other Guarantor, or any other guarantor of
the Lessee's

                                        5


<PAGE>



Liabilities, IT BEING EXPRESSLY UNDERSTOOD, ACKNOWLEDGED AND AGREED TO BY EACH
GUARANTOR THAT DEMAND UNDER THIS GUARANTY AGREEMENT MAY BE MADE BY THE LESSOR,
AND THE PROVISIONS HEREOF ENFORCED BY THE LESSOR, EFFECTIVE AS OF THE FIRST DATE
ANY EVENT OF DEFAULT OCCURS AND IS CONTINUING, or (ii) seek to enforce or resort
to any remedies with respect to any security interests, Liens or encumbrances
granted to the Lessor by the Lessee or any other Person on account of the
Lessee's Liabilities or any guaranty thereof. The Lessor shall not have any
obligation to protect, secure or insure any of the foregoing security interests,
Liens or encumbrances on the properties or interests in properties subject
thereto. The Guarantors' Obligations shall in no way be impaired, affected,
reduced, or released by reason of the Lessor's failure or delay to do or take
any of the acts, actions or things described in this Guaranty Agreement
including, without limiting the generality of the foregoing, those acts, actions
and things described in this SECTION 10.

         (c) Each Guarantor further agrees with respect to this Guaranty
Agreement that, until the Lessee's Liabilities have been paid in full and the
Lenders and the Holders have no further obligation to make any Loan or Holder
Advance, such Guarantor shall have no right of subrogation, reimbursement or
indemnity, nor any right of recourse to security for the Lessee's Liabilities.
This waiver is expressly intended to prevent the existence of any claim in
respect to such reimbursement by any Guarantor against the estate of Lessee
within the meaning of Section 101 of the Bankruptcy Code, and to prevent any
Guarantor from constituting a creditor of Lessee in respect of such
reimbursement within the meaning of Section 547(b) of the Bankruptcy Code in the
event of a subsequent case involving the Lessee.

         (d) Any claim or claims that the Lessor may at any time hereafter have
against any Guarantor under this Guaranty Agreement may be asserted by the
Lessor by written notice directed to such Guarantor.

         10. EFFECTIVENESS; ENFORCEABILITY. This Guaranty Agreement shall be
effective as of the date of the Initial Closing Date and shall continue in full
force and effect until the Lessee's Liabilities are fully paid and the Lease,
the Agency Agreement and the Participation Agreement have terminated in
accordance with their respective terms. The Lessor shall give each Guarantor
written notice of such termination in case of the Lessee at the Lessee's address
set forth in Section 17 below. This Guaranty Agreement shall be binding upon and
inure to the benefit of each Guarantor and the Lessor and their respective
successors and assigns. Notwithstanding the foregoing, no Guarantor may, without
the prior written consent of the Lessor, assign any rights, powers, duties or
obligations hereunder. Each Guarantor acknowledges and agrees that the rights
and powers of the Lessor under this Guaranty have been collaterally assigned to
the Agent pursuant to the terms of the Security Agreement and the other
Operative Agreements.

         11. REPRESENTATIONS AND WARRANTIES. Each Guarantor warrants and
represents to the Lessor that it is duly authorized to execute, deliver and
perform this Guaranty Agreement, that this Guaranty Agreement is legal, valid,
binding and enforceable against such Guarantor in accordance with its terms
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles; and that such
Guarantor's execution, delivery and performance of this Guaranty

                                        6


<PAGE>



Agreement do not violate or constitute a breach of its certificate of
incorporation or other documents of corporate governance or any agreement to
which such Guarantor is a party, or any applicable laws, in each case, which
violation or breach could reasonably be expected to have a material adverse
effect on the business, operations or condition (financial or otherwise) of such
Guarantor.

         12. EXPENSES. Each Guarantor agrees to be liable for the payment of all
fees and expenses, including attorney's fees, incurred by the Lessor in
connection with the enforcement of this Guaranty Agreement.

         13. REINSTATEMENT. Each Guarantor agrees that this Guaranty Agreement
shall continue to be effective or be reinstated, as the case may be, at any time
payment received by the Lessor under the Lease, the Agency Agreement, any other
Operative Agreement or this Guaranty Agreement is rescinded or must be restored
for any reason.

         14. COUNTERPARTS. This Guaranty Agreement may be executed in any number
of counterparts, each of which shall be deemed to be an original as against any
party whose signature appears thereon, and all of which shall constitute one and
the same instrument.

         15. RELIANCE. Each Guarantor represents and warrants to the Lessor
that: (a) such Guarantor has adequate means to obtain from Lessee, on a
continuing basis, information concerning Lessee and Lessee's financial condition
and affairs and has full and complete access to Lessee's books and records; (b)
such Guarantor is not relying on the Lessor, the Agent, any Lender, or any of
their respective employees, agents or other representatives, to provide such
information, now or in the future; (c) such Guarantor is executing this Guaranty
Agreement freely and deliberately, and understands the obligations and financial
risk undertaken by providing this Guaranty; (d) such Guarantor has relied solely
on its own independent investigation, appraisal and analysis of Lessee and
Lessee's financial condition and affairs in deciding to provide this Guaranty
and is fully aware of the same; and (e) such Guarantor has not depended or
relied on the Lessor, the Agent, any Lender, or any of their respective
employees, agents or representatives, for any information whatsoever concerning
Lessee or Lessee's financial condition and affairs or other matters material to
such Guarantor's decision to provide this Guaranty or for any counseling,
guidance, or special consideration or any promise therefor with respect to such
decision. Each Guarantor agrees that neither the Lessor nor the Agent or any
Lender has any duty or responsibility whatsoever, now or in the future, to
provide to such Guarantor any information concerning Lessee or Lessee's
financial condition and affairs, other than as expressly provided herein, and
that, if such Guarantor receives any such information from the Lessor, the
Agent, any Lender, or any of their respective employees, agents or other
representatives, such Guarantor will independently verify the information and
will not rely on the Lessor, the Agent, any Lender, or any of their respective
employees, agents or other representatives, with respect to such information.

         16. TERMINATION. This Guaranty Agreement and all obligations of the
Guarantors hereunder shall terminate without delivery of any instrument or
performance of any act by any party on the date when all of the Lessee's
Liabilities have been fully paid and the Lease, the Agency Agreement and the
Participation Agreement have terminated in accordance with their respective
terms.

                             PARTICIPATION AGREEMENT

         THIS PARTICIPATION AGREEMENT, dated as of December 17, 1998 (as
amended, modified, restated or supplemented from time to time, this
"Agreement"), is by and among AVIATION SALES COMPANY, a Delaware corporation
(the "Construction Agent"); AVIATION SALES COMPANY, as Lessee (the "Lessee");
FIRST SECURITY BANK, NATIONAL ASSOCIATION, a national banking association, not
individually (in its individual capacity, the "Trust Company"), except as
expressly stated herein, but solely as Owner Trustee under the Aviation Sales
Trust 1998-1 (the "Owner Trustee" or the "Lessor"); NATIONSBANK, NATIONAL
ASSOCIATION, as Administrative Agent (in such capacity, the "Agent") for the
Lenders; NATIONSBANK, NATIONAL ASSOCIATION, a national banking association and
the various other banks and lending institutions which are parties hereto from
time to time as Holders; NATIONSBANK, NATIONAL ASSOCIATION and the various other
banks and lending institutions which are parties hereto from time to time as
Lenders. Capitalized terms used but not otherwise defined in this Agreement
shall have the meanings set forth in Appendix A hereto.

         In consideration of the mutual agreements herein contained and other
good and valuable consideration, receipt of which is hereby acknowledged, the
parties hereto hereby agree as follows:

         SECTION 1.  THE LOANS.

         The Lenders have agreed to make Loans to the Lessor from time to time
in an aggregate principal amount of up to the aggregate amount of the
Commitments of the Lenders in order for the Lessor to acquire the Properties and
certain Improvements and to develop and construct certain Improvements in
accordance with the Agency Agreement and the terms and provisions hereof, and in
consideration of the receipt of the proceeds of such Loans, the Lessor will
issue the Notes (together with any note or notes issued in exchange or
substitution therefor in accordance with the Credit Agreement, the "Notes"). The
Loans shall be made and the Notes shall be issued pursuant to the Credit
Agreement. Pursuant to SECTION 5 of this Agreement and SECTION 2 of the Credit
Agreement, the Loans will be made to the Lessor from time to time upon the
appropriate submission by the Construction Agent of a Requisition therefor, in
accordance with this Agreement and the other Operative Agreements. The Loans and
the obligations of the Lessor under the Credit Agreement shall be secured by the
Collateral. The Lessee and the Construction Agent agree that each Property shall
be improved for business purposes and shall not merely be held as unimproved
Land for speculative purposes.

         SECTION 2.  HOLDER FUNDINGS.

         Subject to the terms and conditions of this Agreement and in reliance
on the representations and warranties of each of the parties hereto contained
herein or made pursuant hereto on each date Fundings are made in accordance with
SECTION 5 hereof, each Holder shall make a Holder Funding on a pro rata basis to
the Owner Trustee with respect to the Aviation Sales Trust 1998-1 based on its
Holder Commitment in an amount in immediately available funds such that the
aggregate of all Holder Fundings shall be three percent (3%) of the amount of
the

                                        1


<PAGE>
Funding being funded on such date; provided, no Holder shall be obligated for
any Holder Funding in excess of its pro rata share of the Available Holder
Commitment. The aggregate amount of Holder Fundings shall be up to the aggregate
amount of the Holder Commitments. No prepayment or any other payment with
respect to any Funding shall be permitted such that the Holder Funding with
respect to such Funding is less than 3% of the outstanding amount of such
Funding, except in connection with termination or expiration of the Term or in
connection with the exercise of remedies relating to the occurrence of a Lease
Event of Default. The representations, warranties, covenants and agreements of
the Holders herein and in the other Operative Agreements are several, not joint,
and not joint and several.

         SECTION 3.  SUMMARY OF TRANSACTIONS.

         3.1. OPERATIVE AGREEMENTS. As of the date hereof (the "Initial Closing
Date"), each of the respective parties hereto and thereto shall execute and
deliver this Agreement, the Lease, the Agency Agreement, the Credit Agreement,
the Notes, the Certificates, the Trust Agreement, the Security Agreement and
such other documents, instruments, certificates and opinions of counsel as
agreed to by the parties hereto.

         3.2. PROPERTY PURCHASE. On each Property Closing Date and subject to
the terms and conditions of this Agreement (a) the Holders will each make a
Holder Funding in accordance with SECTIONS 2 AND 5 of this Agreement and the
terms and provisions of the Trust Agreement, (b) the Lenders will make Loans in
accordance with SECTIONS 1 AND 5 of this Agreement and the terms and provisions
of the Credit Agreement, and (c) the Lessor will purchase, or lease pursuant to
a Ground Lease, the applicable Property identified by the Construction Agent,
and grant the Agent a Lien on such Property by execution of the required
Security Documents.

Construction Fundings will be made with respect to particular Improvements to be
constructed and with respect to ongoing Work regarding the Equipment and ongoing
construction of particular Improvements, in each case, pursuant to the terms and
conditions of this Agreement and the Agency Agreement. The Construction Agent
will act as a construction agent on behalf of the Lessor respecting such Work
and the construction of such Improvements and the expenditures of the
Construction Fundings related thereto. The Construction Agent shall promptly
notify the Lessor upon Completion of the Improvements with respect to each
Property.

provision of this Participation Agreement or any other Operative Agreement,

Property, there shall be only one Property as described in the definition of

                  (a) The Construction Agent shall designate the date for
         Fundings hereunder in accordance with the terms and provisions hereof;
         provided, however, it is understood and agreed that no more than one
         (1) Funding may be requested during any calendar month other than
         Fundings which are made solely to fund interest and Holder Yield. Not
         less than five (5) Business Days prior to the date of any requested
         Base Rate Funding or Eurodollar Funding, the Construction Agent shall

         performed, each of the foregoing in a form reasonably acceptable to the
         Lessor and the Agent) and (B) with respect to each Construction
         Funding, a Requisition identifying (among other things) the Property to

         Requisition for an Acquisition Funding) shall be delivered to the
         Lessor and the Agent on a date between (and including) the first (1st)
         and the fifth (5th) Business Day of a calendar month.

                  (b) Each Requisition shall: (i) be irrevocable, (ii) request
         funds in an amount that is not in excess of the total aggregate of the
         Available Commitments plus the Available Holder Commitments at such
         time, and (iii) request that the Holders make Holder Fundings and that
         the Lenders make Loans to the Lessor for the payment of the Property
         Acquisition Costs (in the case of an Acquisition Funding) or other
         Property Costs, including the cost of Improvements (in the case of a
         Construction Funding) that have previously been incurred and were not
         subject to a prior Requisition, in each case as specified in the
         Requisition.

                  (c) Subject to the terms and conditions of the Credit
         Agreement and the Trust Agreement and subject to the satisfaction of
         the conditions precedent set forth in SECTIONS 5.3, 5.4 or 5.5, as
         applicable, on each Property Closing Date or the date on which the

                           (i) the Lenders shall make Loans to the Lessor in an
                  aggregate amount equal to 97% of the sum of (A) the Requested
                  Funds specified in any Requisition, (B) any additional amount

Completion Date for each Property, the Construction Agent shall deliver to the
Agent, and the Owner Trustee an Officer's Certificate in the form attached
hereto as EXHIBIT B specifying (a) the Completion Date for the construction of
Improvements at the Property, (b) the aggregate Property Cost for the Property
and (c) if any of the Property consists of Tangible Personal Property, a
separate statement of the Property Cost attributable to such Tangible Personal
Property. Such Officer's Certificate shall also include, in form and in detail
reasonably acceptable to the Agent and the Holders, a summary of the Property
Cost figures and a certification to the effect that all Improvements have been
made in accordance with all applicable material Legal Requirements, in a good
and workmanlike manner and otherwise in substantial compliance with the
standards and practices of the Construction Agent with respect to similar
properties and improvements owned by the Construction Agent, and that no consent
or approval of any Person is required for such Improvements except for consents
and approvals which have already been obtained. Furthermore, (i) on the
Completion Date for each Property, the Construction Agent shall deliver or cause
to be delivered originals of the following to the Agent (and copies thereof to
the Owner Trustee) each of which shall be in a form reasonably acceptable to the
Agent: (1) insurance certificates with respect to the Property as required under

amendments or modifications to the Lender Financing Statements or the Lessor
Financing Statements executed by the Lessee and the Lessor; and (ii) on or prior
to the Completion Date for each Property (and in no event later than the date of
the last Funding with respect to such Property, as set forth in Exhibit I), the
Construction Agent shall deliver or cause to be delivered originals of the
following to the Agent (and copies thereof to the Owner Trustee) each of which
shall be in a form reasonably acceptable to the Agent: (1) three copies of a
final as-built survey for the applicable Property, (2) an endorsement of the
title insurance policy regarding such Property, amending the effective date of
such policy to the date of such endorsement and taking no exception for any Lien
on account of materials furnished or labor performed in connection with the
Property, and otherwise showing no title changes or any additional exceptions to

Specifications for such Property. In addition, on the Completion Date for such
Property the Construction Agent covenants and agrees that the recording fees,
documentary stamp taxes or similar amounts paid or required to be paid in
connection with the related Mortgage Instrument shall be in an amount required
by applicable law. If such Property has been completed in accordance with the
Plans and Specifications (excluding immaterial punch list items) and the total
Property Cost of such Property as of the Completion Date (after giving effect to
any Fundings on such date) is less than the amount of Fundings estimated in the
Construction Budget for such Property (such shortfall not in excess of
$2,000,000 being referred to as the "Funding Shortfall"), then on any date on or
after the Completion Date, at the election of the Lessee, upon notice to the
Agent and the Lessor, (y) the Total Commitment and Total Holder Commitment shall
be permanently reduced (in accordance with the Operative Agreements) by an
aggregate amount (not in excess of $2,000,000) equal to the Funding Shortfall
(such reduction to be applied pro rata among the Commitments and Holder
Commitments), and (z) simultaneously with such

 

                                       12


<PAGE>
reduction in Commitments and Holder Commitments, the amount of the Letter of
Credit shall be reduced by an amount equal to the Funding Shortfall.

         5.7. CONSTRUCTION AGENT DELIVERY OF ALLOCATION NOTICE AND CONSTRUCTION
BUDGET MODIFICATIONS. The Construction Agent covenants and agrees to deliver (i)
to the Agent at least five (5) Business Days before any Scheduled Interest
Payment Date during the Commitment Period the Allocation Notice referred to in
the first sentence of SECTION 2.3(B) of the Credit Agreement, and (ii) to the
Agent and the Owner Trustee each month any modification to any Construction
Budget regarding any Property; provided, no Construction Budget may be amended
unless (a) the title insurance policies referenced in SECTION 5.3(B)(VIII) are
also modified or endorsed, if necessary, to provide for insurance in an amount
that satisfies the requirements of SECTION 5.4(F)(I) of this Agreement and, if
necessary, any additional recording fees, documentary stamp taxes or similar
amounts paid in connection with the related Mortgage Instrument in an amount
sufficient to comply with the requirements of SECTION 5.4(F)(II), and (b) after
giving effect to any such amendment the Construction Budget remains in
compliance with the requirements of SECTION 5.4(E) of this Agreement. Any
amendment to the Construction Budget is also subject to the requirements of the
Agency Agreement.

         5.8. INSPECTION OF DOCUMENTS; HOLD HARMLESS; REMOVAL OF PROPERTIES. Any
document or item (including without limitation any environmental report)
delivered to the Agent shall be available for inspection at any time during
ordinary business hours upon reasonable notice by any Lender or Holder. The
Agent shall not incur any liability to any Lender, any Holder, the Owner Trustee
or any other Person (and each Lender, each Holder, the Owner Trustee, the Lessee
and the Construction Agent hereby holds the Agent harmless from any such
liability) as a result of any such document or item, any information contained
therein, the failure to receive any such document, or the Agent's approval of
any Property. In the event the Majority Lenders determine that any environmental
site assessment reveals an Environmental Violation and they or the Agent so
notify the Lessee, then the Lessee shall remedy or purchase such Property in
accordance with SECTIONS 15.2, 16.1 AND 16.2 of the Lease, provided that if the
Property is a Construction Period Property, the Construction Agent shall be
responsible for such remedy or purchase.

         if in the future it should decide to dispose of its interest in the
         Trust Estate, it understands that it may do so only in compliance with
         the Securities Act and the rules and regulations of the Securities and
         Exchange Commission thereunder and any applicable state securities

         affect its ability, in its individual capacity or as Owner Trustee, to
         perform its obligations under the Operative Agreements to which it is a
         party or would question the validity or enforceability of any of the
         Operative Agreements to which it is or will become a party;

         Property, or in any security the offering of which for the purposes of
         the Securities Act would be deemed to be part of the same offering as
         the offering of the aforementioned securities to, or solicited any
         offer to acquire any of the same from, any Person other than, in the
         case of the Notes, the Lenders, and neither the Owner Trustee nor any
         Person authorized by the Owner Trustee to act on its behalf will take

         alone, the issuance or sale of any interest in the Trust Estate or the
         Notes to the provisions of Section 5 of the Securities Act, or require
         the qualification of any Operative Agreement under the Trust Indenture
         Act of 1939, as amended;

         Construction Agent and the Lessee and their Subsidiaries on a

                  4975 or ERISA;

                  current value of the assets of such employee benefit plans
                  allocable to such benefits;

                           (D) The consummation of the transactions contemplated
                  by the Operative Agreements will not involve any prohibited

supplements requested by the Lessee with respect to any of the Operative
Agreements, whether or not such amendments or supplements are ultimately entered
into, or giving or withholding of waivers of consents hereto or thereto which
have been requested by the Lessee, or any purchase of any Property by the Lessee
pursuant to ARTICLE XX of the Lease, (ii) all reasonable costs and expenses
(including reasonable counsel fees and expenses) incurred by the Lessor, the
Construction Agent, the Lessee, the Holders, the Lenders or the Agent in
connection with the enforcement of any Operative Agreement or any exercise of
remedies under any Operative Agreement, and (iii) (following the Completion Date

                                       32


<PAGE>
successor owner trustee, for acting as owner trustee under the Trust Agreement.
From the date of this Agreement through the Completion Date for the initial
Property, the Owner Trustee shall cause to be paid the initial and annual Owner
Trustee's fee and all reasonable expenses of the Owner Trustee and any necessary
co-trustees (including reasonable outside counsel fees and expenses) or any
successor owner trustee, (a) to the extent, but only to the extent, amounts are
available therefor under the Available Commitments and Available Holder
Commitments and (b) unless each Lender and each Holder has declined in writing
to fund such amount. Notwithstanding any other provision in any other Operative
Agreement to the contrary, all amounts so advanced shall be deemed added to the
Property Cost of all the Properties (ratably with respect to each Property,
based on the ratio of the Property Cost for such Property individually to the
aggregate Property Cost of all Properties at such time).

         9.3. UNUSED FEE AND HOLDER UNUSED FEE. From the date hereof through the
Construction Period Termination Date, the Owner Trustee shall pay (a) to the
Agent, for the pro rata benefit of the Lenders of each Category of Loans based
on the Commitment Percentage of each such Lender during the period for which
payment is made, the Unused Fee; and (b) to the Lessor, for the pro rata benefit
of the Holders based on the Holder Commitment of each such Holder during the
period for which payment is made, the Holder Unused Fee; PROVIDED that such
amounts under clauses (a) and (b) shall be paid by the Owner Trustee (i) to the
extent, but only to the extent, amounts are available therefor under the
Available Commitments and Available Holder Commitments and (ii) unless each
Lender and each Holder has declined in writing to fund such amount.
Notwithstanding any other provision in any other Operative Agreement to the
contrary, all amounts so advanced shall be deemed added to the Property Cost of
all the Properties (ratably with respect to each Property, based on the ratio of
the Property Cost for such Property individually to the aggregate Property Cost
of all Properties at such time). Such payments of fees provided for in this
SECTION 9.3 shall be due in arrears on each Unused Fee Payment Date.
Notwithstanding the foregoing, so long as any Lender or Holder fails (in
violation of the Operative Agreements) to make available any portion of its
Commitment or Holder Commitment when requested, such Person shall not be
entitled to receive payment of its pro rata share of its Unused Fee or Holder
Unused Fee (as the case may be) until such Person shall make available such
portion. Each such fee shall be calculated on the basis of a year of 360 days
for the actual number of days elapsed. If all or a portion of any Unused Fee or
Holder Unused Fee shall not be paid when due, such overdue amount shall bear
interest, payable by the Lessee on demand, at a rate per annum equal to the Base
Rate plus 2%, from the date of such non-payment until such amount is paid in
full (as well after as before judgment).

         SECTION 10.  OTHER COVENANTS AND AGREEMENTS.

         10.1. COOPERATION WITH THE CONSTRUCTION AGENT OR THE LESSEE. The
Holders, the Owner Trustee (at the direction of the Holders) and the Agent
shall, to the extent reasonably requested by the Construction Agent or Lessee
(but without assuming additional liabilities on account thereof), at the
Construction Agent's or the Lessee's expense, cooperate with the Construction
Agent or the Lessee in connection with its covenants contained herein including,
without limitation, at any time and from time to time, upon the request of the
Construction Agent or the Lessee, promptly and duly executing and delivering any

         Section) in respect of the Properties, and (iii) upon and during the

         Covenants and any other covenants set forth in (or incorporated by
         reference into) Article XXVIII of the Lease, in accordance with their
         respective terms.

                  (j) The Lessee and the Construction Agent shall take all
         reasonable and necessary steps to identify any wetlands, tidelands or
         swamp and overflow lands on any Property prior to development of, or

         notice to the Agent and the Owner Trustee in the event that any
         condition arising from or affecting any Property or arising from or

                                       37

         threatens to have a significant adverse effect upon human health or the
         environment at such Property or upon the use or value of such Property.

         10.4. SHARING OF CERTAIN PAYMENTS. The parties hereto acknowledge and
agree that all payments due and owing by the Lessee to the Lessor under the
Lease or any of the other Operative Agreements shall be made by the Lessee
directly to the Agent as more particularly provided in SECTION 10.3 hereof. The
Holders and the Agent, on behalf of the Lenders, acknowledge the terms of
SECTION 8 of the Credit Agreement regarding the allocation of payments and other
amounts made or received from time to time under the Operative Agreements and
agree all such payments and amounts are to be allocated as provided in SECTION 8
of the Credit Agreement. In connection therewith the Holders hereby (a) appoint

granted by the Mortgage Instruments to secure the Holder Amount and (b)
acknowledge and agree and direct that the rights and remedies of the
beneficiaries of the Lien of the Mortgage Instruments shall be exercised by the
Agent on behalf of the Lenders and the Holders as directed from time to time by
the Lenders without notice to or consent from the Holders.

         10.5. GRANT OF EASEMENTS, VOTING AT MEETINGS, ETC. The Agent and the
Holders hereby agree that, so long as no Event of Default shall have occurred
and be continuing, and until such time as the Agent gives instructions to the

request of the Lessee, in connection with the transactions contemplated by the
Agency Agreement, the Lease or the other Operative Agreements, (i) grant
easements and other rights in the nature of easements with respect to any
Property, (ii) release existing easements or other rights in the nature of
easements which are for the benefit of any Property, (iii) execute and deliver
to any Person any instrument appropriate to confirm or effect such grants or
releases, and (iv) execute and deliver to any Person such other documents or
materials in connection with the acquisition, development or operation of any
Property, including, without limitation, reciprocal easement agreements,
operating agreements, development agreements, plats, replats or subdivision
documents; provided, that each of the agreements and documents referred to in
this SECTION 10.5 shall be of the type normally executed by the Lessee in the
ordinary course of the Lessee's business and shall be on commercially reasonable
terms so as not to diminish the value of any Property in any material respect.

         SECTION 11.  CREDIT AGREEMENT AND TRUST AGREEMENT.

         11.1. CONSTRUCTION AGENT'S AND LESSEE'S CREDIT AGREEMENT RIGHTS.
Notwithstanding anything to the contrary contained in the Credit Agreement, the

         Commitments pursuant to SECTION 2.5(A) of the Credit Agreement;

                  (d) the Lessee shall have the right to exercise the conversion
         and continuation options pursuant to SECTION 2.7 of the Credit
         Agreement;

                  (e) the Lessee shall have the right to approve any successor
         agent pursuant to SECTION 7.9 of the Credit Agreement;

                  (f) the Lessee shall have the right to consent to any
         assignment by a Lender to which the Lessor has the right to consent

                  (g) without limiting the foregoing clauses (a) through (f),
         and in addition thereto, the Lessee shall have the right to exercise
         any other right of the Owner Trustee under the Credit Agreement upon
         not less than five (5) Business Days' prior written notice from the
         Lessee to the Owner Trustee and the Agent.

         11.2. CONSTRUCTION AGENT'S AND LESSEE'S TRUST AGREEMENT RIGHTS.
Notwithstanding anything to the contrary contained in the Trust Agreement, the
Construction Agent, the Lessee, the Owner Trustee and the Holders hereby agree
that, prior to the occurrence and continuation of any Lease Default or Lease
Event of Default, the Construction Agent and the Lessee (as designated below)
shall have the following rights:

                  (a) the Construction Agent shall have the right and the
         obligation (as more specifically provided in SECTION 5.7 hereof) to
         designate the portion of the Holder Fundings on which Holder Yield is
         due and payable for purposes of the definition of Allocated Return in
         this Agreement;

                  (b) the Lessee shall have the right to exercise the conversion
         and continuation options pursuant to SECTION 3.8 of the Trust
         Agreement;

                  (c) no removal of the Owner Trustee or appointment of a
         successor Owner Trustee pursuant to SECTION 9.1 of the Trust Agreement
         shall be made without the prior written consent (not to be unreasonably
         withheld or delayed) of the Lessee; and

                  (d) the Holders and the Owner Trustee shall not amend,
         supplement or otherwise modify any provision of the Trust Agreement in
         such a manner as to adversely affect the rights of the Lessee without
         the prior written consent (not to be unreasonably withheld or delayed)
         of the Lessee.

         SECTION 12.  TRANSFER OF INTEREST.

 

                                       39


<PAGE>
         12.1. RESTRICTIONS ON TRANSFER. The Holders may, directly or
indirectly, assign, convey or otherwise transfer any of their right, title or
interest in or to the Trust Estate or the Trust Agreement with the prior written
consent of the Agent, and (provided no Default or Event of Default has occurred
and is continuing) the Lessee, and (only if such proposed assignee is not a
Lender) the Majority Lenders (which consent in each case shall not be
unreasonably withheld or delayed), PROVIDED that such consents shall not be
required for an assignment to a Lender or an Affiliate of a Lender. The Owner
Trustee may, subject to the Lien of the applicable Security Documents, but only
with the prior written consent of the Agent, the Holders (which consent may be
withheld by the Agent or the Holders in their sole discretion) and (provided no
Default or Event of Default has occurred and is continuing) the Lessee, directly
or indirectly, assign, convey, appoint an agent with respect to enforcement of,
or otherwise transfer any of the Owner Trustee's right, title or interest in or
to any Property, the Lease, the Trust Agreement, this Agreement (including,
without limitation, any right to indemnification thereunder), or any other
document relating to a Property or any interest in a Property as provided in the
Trust Agreement and the Lease. The provisions of the immediately preceding
sentence shall not apply to the obligations of the Owner Trustee to transfer
Property to the Lessee or a third party purchaser pursuant to ARTICLE XXII of
the Lease upon payment for such Property in accordance with each of the terms
and conditions of the Lease.

         12.2. EFFECT OF TRANSFER. From and after any transfer effected in
accordance with this SECTION 12, the transferor shall be released, to the extent
of such transfer, from its liability hereunder and under the other documents to
which it is a party in respect of obligations to be performed on or after the
date of such transfer; provided, however, that any transferor Holder shall
remain liable under ARTICLE XI of the Trust Agreement to the extent that the
transferee Holder shall not have assumed the obligations of the transferor
Holder thereunder. Upon any transfer by the Owner Trustee or a Holder as above
provided, any such transferee shall assume the obligations of the Owner Trustee
and Lessor or the obligations of a Holder, as the case may be, and shall be
deemed an "Owner Trustee", "Lessor" or "Holder", as the case may be, for all
purposes of such documents and each reference herein to the transferor shall
thereafter be deemed a reference to such transferee for all purposes, except as
provided in the preceding sentence. Notwithstanding any transfer of all or a
portion of the transferor's interest as provided in this SECTION 12, the
transferor shall be entitled to all benefits accrued and all rights vested prior
to such transfer including, without limitation, rights to indemnification under
any such document.

         SECTION 13.  INDEMNIFICATION.

         13.1. GENERAL INDEMNITY. Subject to the provisions of SECTIONS 13.4 AND
13.5, and whether or not any of the transactions contemplated hereby shall be
consummated, the Indemnity Provider hereby assumes liability for and agrees to
defend, indemnify and hold harmless each Indemnified Person on an After Tax
Basis from and against any Claims which may be imposed on, incurred by or
asserted against an Indemnified Person by any other Person (but not to the
extent such Claims arise from the gross negligence or willful misconduct of such
Indemnified Person) in any way relating to or arising, or alleged (by any Person
asserting such a Claim against an Indemnified Person) to arise, out of the
execution, delivery, performance or enforcement of this Agreement, the Lease,
any other Operative Agreement or on or with respect to any Property or any part
thereof, including, without limitation, Claims in any way relating to or arising
or alleged to arise out of (a) the financing, refinancing, purchase, acceptance,
rejection, ownership, design,

 

                                       40


<PAGE>
construction, refurbishment, development, delivery, acceptance, nondelivery,
leasing, subleasing, possession, use, operation, maintenance, repair,
modification, transportation, condition, sale, return, repossession (whether by
summary proceedings or otherwise), or any other disposition of a Property, or
any part thereof, including the acquisition, holding or disposition of any
interest in any Property, lease or agreement comprising a portion of any
thereof; (b) any latent or other defect in any property whether or not
discoverable by an Indemnified Person or the Indemnity Provider; (c) any
Environmental Claim, any violation of Environmental Laws, or any other loss of
or damage to any property or the environment relating to any Property, the
Lease, the Agency Agreement or the Indemnity Provider; (d) the Operative
Agreements, or any transaction contemplated thereby; (e) any breach by the
Construction Agent or the Lessee of any of its representations or warranties
under the Operative Agreements to which it is a party or failure by the
Construction Agent or the Lessee to perform or observe any covenant or agreement
to be performed by it under any of the Operative Agreements; (f) the
transactions contemplated hereby or by any other Operative Agreement, in respect
of the application of Parts 4 and 5 of Subtitle B of Title I of ERISA; (g) any
personal injury, death or property damage, including without limitation Claims
based on strict or absolute liability in tort; (h) any easement, right,
agreement or document referred to in SECTION 10.5 of this Agreement; or (i) any
Lien on any Property (other than Liens created by the Operative Agreements).

         If a written Claim is made against any Indemnified Person or if any
proceeding shall be commenced against such Indemnified Person (including a
written notice of such proceeding) for any Claim, such Indemnified Person shall
promptly notify the Indemnity Provider in writing and shall not take action with
respect to such Claim without the consent of the Indemnity Provider for thirty
(30) days after the receipt of such notice by the Indemnity Provider; PROVIDED,
HOWEVER, that, in the case of any such Claim, if action shall be required by law
or regulation to be taken prior to the end of such 30-day period, such
Indemnified Person shall endeavor, in such notice to the Indemnity Provider, to
inform the Indemnity Provider of such shorter period, and no action shall be
taken with respect to such Claim without the consent of the Indemnity Provider
before seven (7) days before the end of such shorter period; PROVIDED, FURTHER,
that the failure of such Indemnified Person to give the notices referred to in
this sentence shall not diminish the Indemnity Provider's obligation hereunder
except to the extent such failure materially precludes the Indemnity Provider
from contesting such Claim.

         If, within thirty (30) days of receipt of such notice from the
Indemnified Person (or such shorter period as the Indemnified Person has
notified the Indemnity Provider is required by law or regulation for the
Indemnified Person to respond to such Claim), the Indemnity Provider shall
request in writing that such Indemnified Person respond to such Claim, the
Indemnified Person shall, at the expense of the Indemnity Provider, in good
faith conduct and control such action (including, without limitation by pursuit
of appeals) (provided, however, that (A) if such Claim can be pursued by the
Indemnity Provider on behalf of or in the name of such Indemnified Person, the
Indemnified Person, at the Indemnity Provider's request, shall allow the
Indemnity Provider to conduct and control the response to such Claim and (B) in
the case of any Claim, the Indemnified Person may request the Indemnity Provider
to conduct and control the response to such Claim (with counsel to be selected
by the Indemnity Provider and consented to by such Indemnified Person, such
consent not to be unreasonably withheld, conditioned or delayed; provided,
however, that any Indemnified Person may retain separate counsel at the expense
of the Indemnity Provider in the event of a conflict)) by, in the sole
discretion of the Person conducting and

 

                                       41


<PAGE>
controlling the response to such Claim, (1) resisting payment thereof, (2) not
paying the same except under protest, if protest is necessary and proper, (3) if
the payment be made, using reasonable efforts to obtain a refund thereof in
appropriate administrative and judicial proceedings, or (4) taking such other
action as is reasonably requested by the Indemnity Provider from time to time.

         The party controlling the response to any Claim shall consult in good
faith with the non-controlling party and shall keep the non-controlling party
reasonably informed as to the conduct of the response to such Claim; PROVIDED,
that all decisions ultimately shall be made in the discretion of the controlling
party, except that the Indemnity Provider may not agree to any dismissal or
settlement of, or other agreement in connection with, any claim without the
prior written consent of such Indemnified Person, if such dismissal, settlement
or agreement would require any admission or acknowledgment of any culpability or
wrongdoing by such Indemnified Person or provide for any nonmonetary relief to
be performed by such Indemnified Person. The parties agree that an Indemnified
Person may at any time decline to take further action with respect to the
response to such Claim and may settle such Claim if such Indemnified Person
shall waive its rights to any indemnity from the Indemnity Provider that
otherwise would be payable in respect of such Claim (and any future Claim, the
pursuit of which is precluded by reason of such resolution of such Claim) and
shall pay to the Indemnity Provider any amount previously paid or advanced by
the Indemnity Provider pursuant to this SECTION 13.1 by way of indemnification
or advance for the payment of any amount regarding such Claim other than
expenses of the action relating to such Claim.

         Notwithstanding the foregoing provisions of this SECTION 13.1, an
Indemnified Person shall not be required to take any action and no Indemnity
Provider shall be permitted to respond to any Claim in its own name or that of
the Indemnified Person unless (A) the Indemnity Provider shall have agreed to
pay and shall pay to such Indemnified Person on demand and on an After Tax Basis
all reasonable costs, losses and expenses that such Indemnified Person actually
incurs in connection with such Claim, including, without limitation, all
reasonable legal, accounting and investigatory fees and disbursements, (B) the
Indemnified Person shall have reasonably determined that the action to be taken
will not result in any material danger of sale, forfeiture or loss of any
Property, or any part thereof or interest therein, will not interfere with the
payment of Rent, and will not result in risk of criminal liability, (C) if such
Claim shall involve the payment of any amount prior to the resolution of such
Claim, the Indemnity Provider shall provide to the Indemnified Person an
interest-free advance in an amount equal to the amount that the Indemnified
Person is required to pay (with no additional net after-tax cost to such
Indemnified Person), (D) in the case of a Claim that must be pursued in the name
of an Indemnified Person (or an Affiliate thereof), the Indemnity Provider shall
have provided to such Indemnified Person an opinion of independent counsel
selected by the Indemnified Person and reasonably satisfactory to the Indemnity
Provider stating that a reasonable basis exists to contest such Claim, (E) such
claim is covered by insurance and (F) no Event of Default shall have occurred
and be continuing. In addition, an Indemnified Person shall not be required to
contest any Claim in its name (or that of an Affiliate) if the subject matter
thereof shall be of a continuing nature and shall have previously been decided
adversely by a court of competent jurisdiction pursuant to the contest
provisions of this SECTION 13.1, unless there shall have been a change in law
(or interpretation thereof) and the Indemnified Person shall have received, at
the Indemnity Provider's expense, an opinion of independent counsel selected by
the Indemnified Person and reasonably acceptable to the

 

                                       42


<PAGE>
Indemnity Provider stating that as a result of such change in law (or
interpretation thereof), it is more likely than not that the Indemnified Person
will prevail in such contest.

         13.2.    GENERAL TAX INDEMNITY.

                  (a) Subject to the provisions of SECTIONS 13.4 AND 13.5, and
         the Indemnity Provider shall pay and assume liability for, and does
         hereby agree to indemnify, protect and defend each Property and all
         Indemnified Persons, and hold them harmless against, all Impositions on
         an After Tax Basis.

                  (b) (i) Subject to the terms of SECTION 13.2(F), the Indemnity
                  Provider shall pay or cause to be paid all Impositions
                  directly to the taxing authorities where feasible and
                  otherwise to the Indemnified Person, as appropriate, and the
                  Indemnity Provider shall at its own expense, upon such
                  Indemnified Person's reasonable request, furnish to such
                  Indemnified Person copies of official receipts or other
                  satisfactory proof evidencing such payment.

                           (ii) In the case of Impositions for which no contest
                  is conducted pursuant to SECTION 13.2(F) and which the
                  Indemnity Provider pays directly to the taxing authorities,
                  the Indemnity Provider shall pay such Impositions prior to the
                  latest time permitted by the relevant taxing authority for
                  timely payment. In the case of Impositions for which the
                  Indemnity Provider reimburses an Indemnified Person, the
                  Indemnity Provider shall do so within thirty (30) days after
                  receipt by the Indemnity Provider of demand by such
                  Indemnified Person describing in reasonable detail the nature
                  of the Imposition and the basis for the demand (including the
                  computation of the amount payable). In the case of Impositions
                  for which a contest is conducted pursuant to SECTION 13.2(F),
                  the Indemnity Provider shall pay such Impositions or reimburse
                  such Indemnified Person for such Impositions, to the extent
                  not previously paid or reimbursed pursuant to subsection (a),
                  prior to the latest time permitted by the relevant taxing
                  authority for timely payment after conclusion of all contests
                  under SECTION 13.2(F).

                           (iii) Impositions imposed with respect to a Property
                  for a billing period during which the Lease expires or
                  terminates with respect to such Property (unless the Lessee
                  has exercised the Purchase Option with respect to such
                  Property or the Lessee has otherwise purchased such Property)
                  shall be adjusted and prorated on a daily basis between the
                  Indemnity Provider and the Lessor, whether or not such
                  Imposition is imposed before or after such expiration or
                  termination and each party shall pay its pro rata share
                  thereof.

                           (iv) At the Indemnity Provider's request, the amount
                  of any indemnification payment by the Indemnity Provider
                  pursuant to subsection (a) shall be verified and certified by
                  an independent public accounting firm mutually acceptable to
                  the Indemnity Provider and the Indemnified Person. The fees
                  and expenses of such independent public accounting firm shall
                  be paid by the Indemnity Provider unless such verification
                  shall result in an adjustment in the Indemnity

 

                                       43


<PAGE>
                  Provider's favor of 15% or more of the payment as computed by
                  the Indemnified Person, in which case such fee shall be paid
                  by the Indemnified Person.

                           (v) The Indemnified Persons shall use good faith
                  efforts to take lawful deductions in their respective tax
                  returns so as to reduce the Impositions required to be
                  reimbursed by the Indemnity Provider hereunder; PROVIDED,
                  HOWEVER, that the failure of any Indemnified Person to take
                  any deduction shall not impair in any way such Person's right
                  to indemnification from the Indemnity Provider for any
                  Impositions.

                  (c) (i) The Indemnity Provider shall be responsible for
         preparing and filing any real and personal property or ad valorem tax
         returns with respect to each Property. In case any other report or tax
         return shall be required to be made with respect to any obligations of
         the Indemnity Provider under or arising out of subsection (a) and of
         which the Indemnity Provider has knowledge or should have knowledge,
         the Indemnity Provider, at its sole cost and expense, shall notify the
         relevant Indemnified Person of such requirement and (except if such
         Indemnified Person notifies the Indemnity Provider that such
         Indemnified Person intends to file such report or return) (A) to the
         extent required or permitted by and consistent with Legal Requirements,
         make and file in Indemnity Provider's name such return, statement or
         report; and (B) in the case of any other such return, statement or
         report required to be made in the name of such Indemnified Person,
         advise such Indemnified Person of such fact and prepare such return,
         statement or report for filing by such Indemnified Person or, where
         such return, statement or report shall be required to reflect items in
         addition to any obligations of the Indemnity Provider under or arising
         out of subsection (a), provide such Indemnified Person at the Indemnity
         Provider's expense with information sufficient to permit such return,
         statement or report to be properly made with respect to any obligations
         of the Indemnity Provider under or arising out of subsection (a). Such
         Indemnified Person shall, upon the Indemnity Provider's request and at
         the Indemnity Provider's expense, provide any data maintained by such
         Indemnified Person (and not otherwise available to or within the
         control of the Indemnity Provider) with respect to any Property which
         the Indemnity Provider may reasonably require to prepare any required
         tax returns or reports.

                  (d) If as a result of the payment or reimbursement by the
         Indemnity Provider of any Imposition or other reasonable expenses of
         the Lessor or the payment of any Transaction Expenses incurred in
         connection with the transactions contemplated by the Operative
         Agreements, the Lessor, the Holders or partners of any Holder shall
         suffer a net increase in any federal, state or local income tax
         liability, the Indemnity Provider shall indemnify such Persons (without
         duplication of any indemnification required by subsection (a)) on an
         After Tax Basis for the amount of such increase. The calculation of any
         such net increase shall take into account any current or future tax
         savings (including tax deductions, net operating loss carry-forward or
         tax credits) realized or reasonably expected to be realized by such
         Person in respect thereof, as well as any interest, penalties and
         additions to tax payable by such Lessor, or such Holder, or such
         Affiliate, in respect thereof.

                  (e) As between the Indemnity Provider on one hand, and the
         Lessor or the Agent, any Lender or any Holder on the other hand, the
         Indemnity Provider shall be responsible for, and the Indemnity Provider
         shall indemnify and hold harmless the Lessor, the Agent, the Lenders
         and each Holder (without duplication of any indemnification required by
         subsection (a)) on an After Tax Basis against, any obligation for
         United States or foreign withholding taxes imposed in respect of
         payments on the Notes or Certificates or with respect to Rent payments
         under the Lease (and, if the Lessor, the Agent, any Lender or any
         Holder receives a demand for such payment from any taxing authority,
         the Indemnity Provider shall discharge such demand on behalf of the
         Lessor, the Agent, such Lender or such Holder); provided, however, that
         the right of any Lender to make a claim for indemnification under this
         SECTION 13.2(E) is subject to the compliance by such Lender with the
         requirements of SECTION 2.13 of the Credit Agreement.

                  (f) (i)  If a written Claim is made against any Indemnified
                           Person, or if any proceeding shall be commenced
                           against such Indemnified Person (including a written
                           notice of such proceeding), for any Impositions, such
                           Indemnified Person shall promptly notify the
                           Indemnity Provider in writing and shall not take
                           action with respect to such Claim or proceeding
                           without the consent of the Indemnity Provider for
                           thirty (30) days after the receipt of such notice by
                           the Indemnity Provider; PROVIDED, HOWEVER, that, in
                           the case of any such Claim or proceeding, if action
                           shall be required by law or regulation to be taken
                           prior to the end of such 30-day period, such
                           Indemnified Person shall, in such notice to the
                           Indemnity Provider, inform the Indemnity Provider of
                           such shorter period, and no action shall be taken
                           with respect to such Claim or proceeding without the
                           consent of the Indemnity Provider before seven (7)
                           days before the end of such shorter period; PROVIDED,
                           FURTHER, that the failure of such Indemnified Person
                           to give the notices referred to this sentence shall
                           not diminish the Indemnity Provider's obligation
                           hereunder except to the extent such failure precludes
                           the Indemnity Provider from contesting such Claim.

                      (ii) If, within thirty (30) days of receipt of such notice
                           from the Indemnified Person (or such shorter period
                           as the Indemnified Person has notified the Indemnity
                           Provider is required by law or regulation for the
                           Indemnified Person to commence such contest), the
                           Indemnity Provider shall request in writing that such
                           Indemnified Person contest such Imposition, the
                           Indemnified Person shall, at the expense of the
                           Indemnity Provider, in good faith conduct and control
                           such contest (including, without limitation, by
                           pursuit of appeals) relating to the validity,
                           applicability or amount of such Imposition (provided,
                           however, that (A) if such contest can be pursued
                           independently from any other proceeding involving a
                           tax liability of such Indemnified Person, the
                           Indemnified Person, at the Indemnity Provider's
                           request, shall allow the Indemnity Provider to
                           conduct and control such contest and (B) in the case
                           of any contest, the Indemnified Person may request
                           the Indemnity Provider to conduct and control such
                           contest (with counsel to be selected by the Indemnity
                           Provider and consented to by such Indemnified Person,
                           such consent not to be unreasonably withheld,
                           conditioned or delayed; provided, however, that any
                           Indemnified Person may retain separate counsel at the
                           expense of the Indemnity Provider in the event of a
                           conflict)) by, in the sole discretion of

 

                                       45


<PAGE>
                  the Person conducting and controlling such contest, (1)
                  resisting payment thereof, (2) not paying the same except
                  under protest, if protest is necessary and proper, (3) if the
                  payment be made, using reasonable efforts to obtain a refund
                  thereof in appropriate administrative and judicial
                  proceedings, or (4) taking such other action as is reasonably
                  requested by the Indemnity Provider from time to time.

                           (iii) The party controlling any contest shall consult
                  in good faith with the non-controlling party and shall keep
                  the non-controlling party reasonably informed as to the
                  conduct of such contest; PROVIDED, that all decisions
                  ultimately shall be made in the sole discretion of the
                  controlling party, except that the Indemnity Provider may not
                  agree to any dismissal or settlement of, or other agreement in
                  connection with, any claim without the prior written consent
                  of such Indemnified Person, if such dismissal, settlement or
                  agreement would require any admission or acknowledgment of any
                  culpability or wrongdoing by such Indemnified Person or
                  provide for any nonmonetary relief to be performed by such
                  Indemnified Person. The parties agree that an Indemnified
                  Person may at any time decline to take further action with
                  respect to the contest of any Imposition and may settle such
                  contest if such Indemnified Person shall waive its rights to
                  any indemnity from the Indemnity Provider that otherwise would
                  be payable in respect of such Imposition (and any future Claim
                  by any taxing authority, the contest of which is precluded by
                  reason of such resolution of such contest) and shall pay to
                  the Indemnity Provider any amount previously paid or advanced
                  by the Indemnity Provider pursuant to this SECTION 13.2 by way
                  of indemnification or advance for the payment of any amount
                  regarding such Imposition other than expenses of such contest.

                           (iv) Notwithstanding the foregoing provisions of this
                  SECTION 13.2, an Indemnified Person shall not be required to
                  take any action and no Indemnity Provider shall be permitted
                  to contest any Imposition in its own name or that of the
                  Indemnified Person unless (A) the Indemnity Provider shall
                  have agreed to pay and shall pay to such Indemnified Person on
                  demand and on an After Tax Basis all reasonable costs, losses
                  and expenses that such Indemnified Person actually incurs in
                  connection with contesting such Imposition, including, without
                  limitation, all reasonable legal, accounting and investigatory
                  fees and disbursements, (B) the Indemnified Person shall have
                  reasonably determined that the action to be taken will not
                  result in any material danger of sale, forfeiture or loss of
                  any Property, or any part thereof or interest therein, will
                  not interfere with the payment of Rent, and will not result in
                  risk of criminal liability, (C) if such contest shall involve
                  the payment of the Imposition prior to or during the contest,
                  the Indemnity Provider shall provide to the Indemnified Person
                  an interest-free advance in an amount equal to the Imposition
                  that the Indemnified Person is required to pay (with no
                  additional net after-tax cost to such Indemnified Person), (D)
                  in the case of a Claim that must be pursued in the name of an
                  Indemnified Person (or an Affiliate thereof), the Indemnity
                  Provider shall have provided to such Indemnified Person an
                  opinion of independent tax counsel selected by the Indemnified
                  Person and reasonably satisfactory to the Indemnity Provider
                  stating that a reasonable basis exists to contest such Claim,
                  and (E) no Event of Default shall have occurred and

 

                                       46


<PAGE>
                  be continuing. In addition, an Indemnified Person shall not be
                  required to contest any claim in its name (or that of an
                  Affiliate) if the subject matter thereof shall be of a
                  continuing nature and shall have previously been decided
                  adversely by a court of competent jurisdiction pursuant to the
                  contest provisions of this SECTION 13.2, unless there shall
                  have been a change in law (or interpretation thereof) and the
                  Indemnified Person shall have received, at the Indemnity
                  Provider's expense, an opinion of independent tax counsel
                  selected by the Indemnified Person and reasonably acceptable
                  to the Indemnity Provider stating that as a result of such
                  change in law (or interpretation thereof), it is more likely
                  than not that the Indemnified Person will prevail in such
                  contest.

         13.3. ENVIRONMENTAL INDEMNITY. Without limiting the generality of the
foregoing, whether or not the transactions contemplated hereby shall be
consummated, the Indemnity Provider hereby assumes liability for and agrees to
defend, indemnify and hold harmless each Indemnified Person on an After Tax
Basis from and against any Claims which may be imposed on, incurred by or
asserted against an Indemnified Person by any other Person (but not to the
extent such Claims arise from the gross negligence or willful misconduct of such
Indemnified Person) in any way relating to or arising, or alleged (by any Person
asserting such a Claim against an Indemnified Person) to arise, out of any
Environmental Claim, any violation of Environmental Laws, or any other loss of
or damage to any Property or the environment (including without limitation the
presence on any Property of wetlands, tidelands or swamp or overflow lands, or
any condition arising from or affecting any Property or arising from or
affecting any lands nearby or adjacent to any Property that has or threatens to
have any adverse effect upon human health or the environment at such Property or
upon the use or value of such Property), in each case relating to any Property,
the Lease, the Agency Agreement or the Indemnity Provider.

         13.4. ADDITIONAL PROVISIONS REGARDING INDEMNIFICATION DURING
CONSTRUCTION PERIOD OF A PROPERTY. Notwithstanding the provisions of SECTIONS
13.1, 13.2 AND 13.3, (a) the Owner Trustee shall be the only beneficiary of the
provisions set forth in SECTIONS 13.1, 13.2 AND 13.3, with respect to any
Property during the Construction Period for such Property (except that other
Indemnified Persons may benefit from the Environmental Indemnities to the extent
set forth in clause (c) below); (b) in the case of third-party Claims, the
indemnity benefitting the Owner Trustee referred to in clause (a) above shall be
limited to (i) Claims caused by or resulting from the acts or omissions of the
Indemnity Provider, any contractor or subcontractor of the Indemnity Provider,
or any other Person acting by, through or under the Indemnity Provider or any
such contractor or subcontractor, (ii) Environmental Indemnities, or (iii)
Claims for personal injury or death, property damage, loss or theft, strict
liability, workmen's compensation, and other similar insurable liabilities; and
(c) during the Construction Period of a Property, the indemnity provided with
respect to such Property to Indemnified Persons other than the Owner Trustee
shall be limited to Environmental Indemnities for environmental risks or
conditions that exist on the Property Closing Date for such Property. After the
Construction Period for a Property, each Indemnified Person shall be a
beneficiary of the provisions of SECTIONS 13.1, 13.2 AND 13.3 to the fullest
extent of such provisions.

         13.5. INDEMNIFICATION PROVIDED BY THE OWNER TRUSTEE IN FAVOR OF THE
OTHER INDEMNIFIED PERSONS. To the extent the Indemnity Provider is not obligated
to indemnify any Indemnified Person with respect to the various matters
described in this SECTION 13.5, the Owner Trustee shall,

 

                                       47


<PAGE>
and does hereby, provide such indemnities in favor of each Indemnified Person
(subject to clauses (a) and (b) below) and shall pay all such amounts owed
pursuant to this SECTION 13.5 with amounts advanced by the Lenders and the
Holders (a) to the extent, but only to the extent, amounts are available
therefor under the Available Commitments and Available Holder Commitments and
(b) unless each Lender and each Holder has declined in writing to fund such
amount. Notwithstanding any other provision in any other Operative Agreement to
the contrary, all amounts so advanced shall be deemed added to the Property Cost
of all the Properties (ratably with respect to each Property, based on the ratio
of the Property Cost for such Property individually to the aggregate Property
Cost of all Properties at such time).

         Whether or not any of the transactions contemplated hereby shall be
consummated, the Owner Trustee hereby assumes liability for and agrees to
defend, indemnify and hold harmless each Indemnified Person on an After Tax
Basis from and against any Claims which may be imposed on, incurred by or
asserted against an Indemnified Person by any other Person (but not to the
extent such Claims arise from the gross negligence or willful misconduct of such
Indemnified Person) in any way relating to or arising, or alleged (by any Person
asserting such a Claim against an Indemnified Person) to arise, out of the
execution, delivery, performance or enforcement of this Agreement, the Lease,
any other Operative Agreement or on or with respect to any Property or any part
thereof, including, without limitation, Claims in any way relating to or arising
or alleged to arise out of any of the matters set forth in SECTION 13.1
(including any Claims that would be indemnified by the Indemnity Provider
pursuant to SECTION 13.1 but for the effect of SECTION 13.4).

         The Owner Trustee shall pay and assume liability for, and does hereby
agree to indemnify, protect and defend each Property and all Indemnified
Persons, and hold them harmless against, all Impositions on an After Tax Basis
(including any Impositions that would be paid, assumed or indemnified by the
Indemnity Provider pursuant to SECTION 13.2 but for the effect of SECTION 13.4).

         THE INDEMNITY OBLIGATIONS UNDERTAKEN BY THE OWNER TRUSTEE PURSUANT TO
THIS SECTION 13.5 ARE IN ALL RESPECTS SUBJECT TO THE LIMITATIONS ON LIABILITY
DESCRIBED IN SECTION 14.11.

         SECTION 14.  MISCELLANEOUS.

         14.1. SURVIVAL OF AGREEMENTS. The representations, warranties,
covenants, indemnities and agreements of the parties provided for in the
Operative Agreements, and the parties' obligations under any and all thereof,
shall survive the execution and delivery of this Agreement, the transfer of any
Property to the Owner Trustee, the acquisition of any Equipment, the
construction of any Improvements, any disposition of any interest of the Owner
Trustee in any Property or any interest of the Holders in the Owner Trust, the
payment of the Notes and any disposition thereof, and shall be and continue in
effect notwithstanding any investigation made by any party and the fact that any
party may waive compliance with any of the other terms, provisions or conditions
of any of the Operative Agreements. Except as otherwise expressly set forth
herein or in other Operative Agreements, the indemnities of the parties provided
for in the Operative Agreements shall survive the expiration or termination of
any thereof. In furtherance and not in limitation of the foregoing and
notwithstanding the occurrence of any Closing Date or

 

                                       48


<PAGE>
the completion of any Funding under this Agreement pursuant to SECTION 5.3 OR
5.5, each condition precedent in connection with any such Closing Date or
Funding which is not fully satisfied may be subsequently required by the Agent
to be satisfied (unless such has been expressly waived in writing by the Agent).

         14.2. NO BROKER, ETC. Each of the parties hereto represents to the
others that it has not retained or employed any broker, finder or financial
adviser to act on its behalf in connection with this Agreement, nor has it
authorized any broker, finder or financial adviser retained or employed by any
other Person so to act. Any party who is in breach of this representation shall
indemnify and hold the other parties harmless from and against any liability
arising out of such breach of this representation.

         14.3. NOTICES. Unless otherwise specifically provided herein, all
notices, consents, directions, approvals, instructions, requests and other
communications required or permitted by the terms hereof to be given to any

         action or proceeding in any such court or that such action or

         Agreements to which it is a party (other than the Trust Agreement and
         other than as set forth in SECTION 7.2 of this Agreement), solely in
         its capacity as trustee under the Trust Agreement and not in its
         individual capacity and that Trust Company shall not be liable or
         accountable under any circumstances whatsoever in its individual
         capacity for or on account of any statements, representations,
         warranties, covenants or obligations stated to be those of the Owner
         Trustee, except for its own gross negligence or willful misconduct and
         except as otherwise expressly provided herein or in the other Operative
         Agreements.

                  (b) Anything to the contrary contained in this Agreement, the
         Credit Agreement, the Notes or in any other Operative Agreement
         notwithstanding, neither the Lessor nor any Holder (in its capacity as
         a Holder) nor any officer, director, shareholder, or partner thereof,
         nor any of the successors or assigns of the foregoing (all such Persons
         being hereinafter referred to collectively as the "Exculpated
         Persons"), shall be personally liable in any respect for any liability
         or obligation hereunder or under any other Operative Agreement
         including the payment of the principal of, or interest on, the Notes,
         or for monetary damages for the breach of performance of any of the

                                       53


<PAGE>
         Operative Agreements. The Agent (for itself and on behalf of the
         Lenders) agrees that, in the event the Agent or any Lender pursues any
         remedies available to them under the Credit Agreement, the Notes, this
         Agreement, the Security Agreement, the Mortgage Instruments or under
         any other Operative Agreement, neither the Lenders nor the Agent shall
         have any recourse against any Exculpated Person, for any deficiency,
         loss or Claim for monetary damages or otherwise resulting therefrom,
         and recourse shall be had solely and exclusively against the Trust
         Estate and the Lessee (with respect to the Lessee's obligations under
         the Lease, the Participation Agreement and the Agency Agreement); but
         nothing contained herein shall be taken to prevent recourse against or
         the enforcement of remedies against the Trust Estate in respect of any
         and all liabilities, obligations and undertakings contained herein, in
         the Credit Agreement, in the Notes, in the Security Agreement, the
         Mortgage Instruments or in any other Operative Agreement.
         Notwithstanding the provisions of this Section, nothing in this
         Agreement, the Credit Agreement, the Notes, the Security Agreement, the
         Mortgage Instruments or any other Operative Agreement shall: (i)
         constitute a waiver, release or discharge of any indebtedness or
         obligation evidenced by the Notes or arising under this Agreement, the
         Security Agreement, the Mortgage Instruments or the Credit Agreement or
         secured by the Security Agreement, the Mortgage Instruments or any
         other Operative Agreement, but the same shall continue until paid or
         discharged; (ii) relieve the Lessor or any Exculpated Person from
         liability and responsibility for (but only to the extent of the damages
         arising by reason of): (a) active waste knowingly committed by such
         Lessor or such Exculpated Person with respect to the Properties or (b)
         any fraud, gross negligence, willful misconduct or willful breach on
         the part of such Lessor or such Exculpated Person; (iii) relieve such
         Lessor or such Exculpated Person from liability and responsibility for
         (but only to the extent of the moneys misappropriated, misapplied or
         not turned over) (a) misappropriation or misapplication by such Lessor
         (I.E., application in a manner contrary to any Operative Agreement) of
         any insurance proceeds or condemnation award paid or delivered to such
         Lessor by any Person other than the Agent, (b) any deposits or any
         escrows or amounts owed by the Lessee under the Agency Agreement held
         by such Lessor or (c) any rents or other income received by such Lessor
         from the Lessee that are not turned over to the Agent; or (iv) affect
         or in any way limit the Agent's rights and remedies under any Operative
         Agreement with respect to the Rents and its rights thereunder or its
         right to obtain a judgment against the Lessor's interest in the
         Properties.

         14.12. RIGHTS OF LESSEE. Notwithstanding any provision of the Operative
Agreements, if at any time all obligations (i) of the Owner Trustee under the
Credit Agreement, the Security Documents, the Trust Agreement and the other
Operative Agreements and (ii) of the Lessee under the Operative Agreements have
in each case been satisfied or discharged in full, then the Lessee shall be
entitled to (a) terminate the Lease and (b) receive all amounts then held under
the Operative Agreements and all proceeds with respect to any of the Properties.
Upon the termination of the Lease pursuant to the foregoing clause (a), the
Lessor shall transfer to the Lessee all of its right, title and interest free
and clear of the Lien of the Lease and all Lessor Liens in and to any Properties
then subject to the Lease and any amounts or proceeds referred to in the
foregoing clause (b) shall be paid over to the Lessee.

<PAGE>
         14.13. FURTHER ASSURANCES. The parties hereto shall promptly cause to
be taken, executed, acknowledged or delivered, at the sole expense of the
Lessee, all such further acts, conveyances, documents and assurances as the
other parties may from time to time reasonably request in order to carry out and
effectuate the intent and purposes of this Participation Agreement, the other
Operative Agreements and the transactions contemplated hereby and thereby
(including, without limitation, the preparation, execution and filing of any and
all Uniform Commercial Code financing statements and other filings or
registrations which the parties hereto may from time to time request to be filed
or effected). The Lessee, at its own expense and without need of any prior
request from any other party, shall take such action as may be necessary
(including any action specified in the preceding sentence), or (if Owner Trustee
shall so request) as so requested, in order to maintain and protect all security
interests provided for hereunder or under any other Operative Agreement.

         14.14. CALCULATIONS UNDER OPERATIVE AGREEMENTS. The parties hereto
agree that all calculations and numerical determinations to be made under the
Operative Agreements by the Owner Trustee shall be made by the Agent and that
such calculations and determinations shall be conclusive and binding on the
parties hereto in the absence of manifest error.

         14.15. CONFIDENTIALITY. Each of the Owner Trustee, the Holders, the
Agent and the Lenders severally agrees to use reasonable efforts to keep
confidential all non-public information pertaining to the Lessee or its
Subsidiaries which is provided to it by the Lessee or its Subsidiaries, and
shall not intentionally disclose such information to any Person except:

                  (a) to the extent such information is public when received by
         such Person or becomes public thereafter due to the act or omission of
         any party other than such Person;

                  (b) to the extent such information is independently obtained
         from a source other than the Lessee or any of its Subsidiaries and such
         information from such source is not, to such Person's knowledge,
         subject to an obligation of confidentiality or, if such information is
         subject to an obligation of confidentiality, that disclosure of such
         information is permitted;

                  (c) to any Affiliate of any such Person or to counsel,
         auditors or accountants retained by any such Person or any such
         Affiliate, provided they agree to keep such information confidential as
         if such Person or Affiliate were party to this Agreement and to
         financial institution regulators, including examiners of any Lender,
         the Agent or the Owner Trustee, any Holder or any Affiliate in the
         course of examinations of such Persons;

                  (d) in connection with any litigation or the enforcement or
         preservation of the rights of the Agent, the Owner Trustee, the Lessor,
         any Lender or any Holder under the Operative Agreements;

                  (e) to the extent required by any applicable statute, rule or
         regulation or court order (including, without limitation, by way of
         subpoena) or pursuant to the request of any regulatory or Governmental
         Authority having jurisdiction over any such Person; PROVIDED,

 

                                       55


<PAGE>
         HOWEVER, that such Person shall endeavor (if not otherwise prohibited
         by Law) to notify the Lessee prior to any disclosure made pursuant to
         this clause (e), except that no such Person shall be subject to any
         liability whatsoever for any failure to so notify the Lessee;

                  (f) to the Agent, any Lender or any Holder; or

                  (g) to the extent disclosure to any other financial
         institution or other Person is appropriate in connection with any
         proposed or actual (i) assignment or grant of a participation by any of
         the Lenders of interests in the Credit Agreement or any Note to such
         other financial institution or (ii) assignment by any Holder of
         interests in the Trust Agreement to another Person.

         14.16. CALCULATION OF RENT, INTEREST, HOLDER YIELD AND FEES. Except as
otherwise expressly set forth in the Operative Agreements, all calculation of
Rent, interest, Holder Yield, Overdue Rate, Holder Overdue Rate, Unused Fees, or
Holder Unused Fees payable hereunder shall be computed based on the actual
number of days elapsed over a year of 360 days.

         IN WITNESS WHEREOF, the parties hereto have caused this Participation
Agreement to be duly executed by their respective officers thereunto duly
authorized as of the day and year first above written.
