                            LEASE AGREEMENT [______]

      LEASE AGREEMENT [______], dated as of [_______________] (this "Agreement"
or "Lease"), between (a) WELLS FARGO BANK NORTHWEST, NATIONAL ASSOCIATION, a
national banking association, not in its individual capacity, except as
expressly provided herein, but solely as Owner Trustee (this and all other
capitalized terms used but not defined herein shall have the respective meanings
ascribed thereto in Section 1 below) ("Lessor" or "Owner Trustee"), and (b)
CONTINENTAL AIRLINES, INC., a Delaware corporation ("Lessee").

                                    RECITALS

      A. Lessor and Lessee are parties to the Participation Agreement, pursuant
to which, among other things, Lessor and Lessee have agreed to enter into this
Agreement.

      B. Pursuant to the Trust Agreement, Owner Participant has authorized
Lessor to enter into this Agreement.

      NOW, THEREFORE, for and in consideration of the premises and the mutual
agreements contained herein and for other good and valuable consideration, the
sufficiency and receipt of which are hereby acknowledged, the parties hereto
agree as follows:

SECTION 1.     DEFINITIONS AND CONSTRUCTION

      Capitalized terms used but not defined herein shall have the respective
meanings set forth or incorporated by reference, and shall be construed and
interpreted in the manner described, in Annex A.

SECTION 2.     DELIVERY AND ACCEPTANCE

        2.1    DELIVERY AND LEASE OF AIRCRAFT

      Lessor hereby agrees (subject to the satisfaction or waiver of the
conditions set forth in Section 5 of the Participation Agreement) to lease to
Lessee for the Term and Lessee hereby agrees (subject to the satisfaction or
waiver of the conditions set forth in Section 5 of the Participation Agreement)
to lease from Lessor for the Term, the Aircraft, commencing immediately upon
acquisition of the Aircraft by Lessor pursuant to the Purchase Agreement
Assignment.

<PAGE>

        2.2    ACCEPTANCE BY LESSEE

      (a) By executing and delivering Lease Supplement No. 1, Lessee confirms to
Lessor that Lessee has duly and irrevocably accepted delivery of the Aircraft
for all purposes of this Agreement.

      (b) Lessor has authorized one or more employees of Lessee, designated by
Lessee in writing, as the authorized representative or representatives of Lessor
to accept delivery of the Aircraft on behalf of Lessor pursuant to the Purchase
Agreement Assignment and the Participation Agreement. Lessee hereby agrees that
if delivery of the Aircraft shall be accepted by an employee or employees of
Lessee pursuant to such authorization by Lessor, such acceptance of delivery by
such employee or employees on behalf of Lessor shall, without further act,
irrevocably constitute acceptance by Lessee of the Aircraft for all purposes of
this Agreement.

SECTION 3.     TERM AND RENT

        3.1    TERM

      The Aircraft shall be leased hereunder for the Term, unless this Agreement
or the leasing of the Aircraft is earlier terminated in accordance with any
provision of this Agreement. Lessee shall have the option to renew the leasing
of the Aircraft hereunder pursuant to, and subject to the terms and conditions
of, Section 17, for the Renewal Lease Term.

        3.2    RENT

               3.2.1    INTERIM RENT; BASIC RENT; ADJUSTMENTS TO
                        BASIC RENT AND CERTAIN OTHER AMOUNTS

      (a) Lessee shall pay Interim Rent to Lessor on the last day of the Interim
Lease Term, which shall be allocated to the Interim Lease Term. During the Base
Lease Term, Lessee shall pay to Lessor, on each Payment Date, Basic Rent in the
amount equal to the percentage of Lessor's Cost specified in Schedule 2 for such
Payment Date, which shall be allocated to the Payment Period ending on such
Payment Date, if designated as a payment in arrears, or allocated to the Payment
Period commencing on such Payment Date, if designated as a payment in advance,
in each case as specified in Schedule 2, as such amount may be adjusted pursuant
to Section 3.2.1(b).

<PAGE>

      (b) Basic Rent, Stipulated Loss Values and Termination Values, shall be
subject to adjustment as follows:

            (i) In the event that Transaction Expenses paid by Lessor pursuant
      to Section 9.2 of the Participation Agreement are determined to be other
      than 1.0% of Lessor's Cost, then in each case the Basic Rent percentages
      set forth in Schedule 2, Stipulated Loss Value percentages set forth in
      Schedule 3 and the Termination Value percentages set forth in Schedule 4
      shall be recalculated (upwards or downwards) by the Owner Participant, on
      or prior to the 120th day after the Delivery Date using the same methods
      and assumptions used to calculate original Basic Rent, Stipulated Loss
      Value and Termination Value percentages in order to (1) maintain the Owner
      Participant's Net Economic Return and (2) minimize the Net Present Value
      of Rents to Lessee to the extent possible consistent with clause (1)
      hereof.

            (ii) In the event of a refinancing as contemplated by Section 11 of
      the Participation Agreement, then the Basic Rent percentages set forth in
      Schedule 2, Stipulated Loss Value percentages set forth in Schedule 3 and
      the Termination Value percentages set forth in Schedule 4 shall be
      recalculated (upwards and downwards) by the Owner Participant as
      contemplated by such Section to (1) maintain the Owner Participant's Net
      Economic Return and (2) to the extent possible consistent with clause (1)
      hereof, minimize the Net Present Value of Rents to Lessee.

            (iii) In the event that Lessee is required to indemnify the Owner
      Participant under the Tax Indemnity Agreement, then (A) in the event that
      the Lessee agrees to satisfy such indemnity obligation pursuant to Section
      __ of the Tax Indemnity Agreement, the Basic Rent percentages set forth in
      Schedule 2, and (B) in any event, the Stipulated Loss Value percentages
      set forth in Schedule 3 and the Termination Value percentages set forth in
      Schedule 4 shall be recalculated (upwards or downwards) by Owner
      Participant, using the same methods and assumptions (except to the extent
      such assumptions shall be varied to take into account the Tax Loss or
      Foreign Tax Credit Loss (as each such term is defined in the Tax Indemnity
      Agreement) that is the subject of such indemnification and any prior or
      contemporaneous Tax Loss or Foreign Tax Credit Loss) used to calculate the
      Basic Rent percentages, the Stipulated Loss Value percentages and the
      Termination Value percentages on the Delivery Date, in order to (1)

<PAGE>

      maintain the Owner Participant's Net Economic Return and (2) to the extent
      possible consistent with clause (1) hereof, minimize the Net Present Value
      of Rents to Lessee.

      (c) All adjustments pursuant to Section 3.2.1(b) shall be made as promptly
as practicable after either Owner Participant or Lessee gives notice to the
other that an event has occurred that requires an adjustment. Owner Participant
and Lessee shall give prompt notice to the other of any event requiring an
adjustment. Any recalculation of the percentages of Basic Rent, Stipulated Loss
Value and Termination Value shall be prepared by Owner Participant, subject to
verification at the request of Lessee in accordance with this Section 3.2.1(c),
on the basis of the same methodology and assumptions used by Owner Participant
in determining the percentages of Basic Rent, Stipulated Loss Value and
Termination Value as of the Delivery Date, except as such assumptions have been
modified to reflect the events giving rise to adjustments hereunder. Promptly
after an adjustment is made hereunder, Owner Participant shall deliver to Lessee
a description of such adjustment, setting forth in reasonable detail the
calculation thereof. All adjustments shall (i) be made so as to avoid
characterization of the Lease as a "disqualified leaseback or long-term
agreement" within the meaning of Section 467 of the Code unless such adjustments
are made in a manner that reflects the effect of such characterization and (ii)
be in compliance with the requirements of Sections 4.02(5), 4.07(l) and, on a
prospective basis, 4.08(1) of Revenue Procedure 75-28, except to the extent that
on the Delivery Date the Lease constituted a "disqualified leaseback or
long-term agreement" or was not in compliance with the regulations referred to
in clause (ii). All adjustments required pursuant to Section 3.2.1(b) shall be
set forth in a Lease Supplement or in an amendment to this Lease, and promptly
after execution thereof by Lessor and Lessee, Lessee shall give a copy thereof
to Mortgagee.

      (d) If Lessee believes that any calculations by Owner Participant pursuant
to Section 3.2.1(c) are in error, and if, after consultation, Lessee and Owner
Participant are unable to agree on an adjustment, then a nationally recognized
firm of accountants selected by Lessee and reasonably satisfactory to Owner
Participant shall verify such calculations. Owner Participant will make
available to such firm, but not, in any circumstances, to Lessee or any
representative of Lessee, the methodology and assumptions referred to in Section
3.2.1(c) and any modifications thereto made to reflect the events giving rise to
adjustments hereunder (subject to the execution by such firm of a

<PAGE>

confidentiality agreement, reasonably acceptable to Owner Participant,
prohibiting disclosure of such methodology and assumptions to any third party).
The determination by such firm of accountants shall be final. Lessee will pay
the reasonable costs and expenses of such further verification by such
accountants, provided that if it results in a decrease in Basic Rent which
decreases the remaining Net Present Value of Rents by ten or more basis points
from the remaining Net Present Value of Rents as recalculated by the Owner
Participant, then the Owner Participant will pay such costs and expenses.

      (e) Notwithstanding anything to the contrary in any Operative Agreement,
the amount of the payment of Basic Rent due and payable on each Payment Date
shall be at least sufficient to pay in full, as of such Payment Date (assuming
timely payment of the Equipment Notes prior to such Date), the aggregate
principal amount of scheduled installments due on the Equipment Notes
outstanding on such Payment Date, together with the accrued and unpaid interest
thereon, due on such Payment Date in respect of the Equipment Notes; provided,
however, that no installment of Basic Rent shall be increased to the extent such
increase would be based upon (i) any attachment or diversion of Basic Rent on
account of Lessor Liens, (ii) any modification of the payment terms of the
Equipment Notes, other than as required or permitted by any Operative Agreement
(including, without limitation, as permitted upon the occurrence of a Lease
Event of Default) or (iii) the acceleration of any Equipment Note or Equipment
Notes due solely to the occurrence of an Indenture Event of Default that does
not constitute a Lease Event of Default.

               3.2.2    SUPPLEMENTAL RENT

      Lessee shall pay to Lessor, or to whosoever shall be entitled thereto, any
and all Supplemental Rent when and as the same shall become due and owing.
Lessee will also pay to Lessor, or to whosoever shall be entitled thereto as
Supplemental Rent, to the extent permitted by applicable Law, interest at the
Payment Due Rate on any part of any amount of Rent (including, without
limitation, Supplemental Rent) not paid by 12:30 p.m., New York time, on the
date when due (so long as, in the case of any person not a party to the
Participation Agreement, Lessee had received timely notice of the account to
which such payment was required to be made), for the period from and including
the date on which the same was due to, but excluding, the date of payment in
full.

<PAGE>

        3.3    PAYMENTS

      (a) Payments of Rent by Lessee shall be paid by wire transfer of
immediately available Dollars, not later than 12:30 p.m., New York time, on the
date when due, to the account of Lessor specified in Schedule 1 to the
Participation Agreement or to such other account in the United States as
directed by Lessor to Lessee in writing at least 10 Business Days prior to the
date such payment of Rent is due or, in the case of any payment of Supplemental
Rent expressly payable to a person other than Lessor, to the person that shall
be entitled thereto to such account in the United States as such person may
specify from time to time to Lessee at least 10 Business Days prior to the date
such payment of Rent is due.

      (b) Except as otherwise expressly provided herein, whenever any payment of
Rent shall be due on a day that is not a Business Day, such payment shall be
made on the next day that is a Business Day, and, if such payment is made on
such next Business Day, no interest shall accrue on the amount of such payment
during such extension.

      (c) So long as Lessee has not received written notice from the Mortgagee
that the Lien of the Trust Indenture has been discharged, and notwithstanding
Section 3.3(a), Lessor hereby directs, and Lessee agrees, that all payments of
Rent and all other amounts payable by Lessee hereunder, other than Excluded
Payments, shall be paid directly to Mortgagee on behalf of Lessor by wire
transfer of immediately available Dollars to the account of Mortgagee specified
in Schedule 1 to the Participation Agreement, or to such other account in the
United States as Mortgagee may specify by written notice to Lessor and Lessee at
least 10 Business Days prior to the date such payment of Rent is due.

      (d) Excluded Payments shall be paid by wire transfer of immediately
available Dollars to the account of the person specified in the Participation
Agreement or, if not so specified, to such account in the United States as may
be specified by such person by written notice to Lessor and Lessee from time to
time at least 10 Business Days prior to the date such payment is required to be
made.

      (e) All computations of interest under this Agreement shall be made on the
basis of a year of 360 days comprised of twelve 30-day months.

suppliers, as the case may be, pursuant to and in accordance with the terms of
the Purchase Agreement Assignment.

        4.3    QUIET ENJOYMENT

      So long as no Lease Event of Default shall have occurred and be
continuing, Lessor shall not interfere with Lessee's rights hereunder to

during the Term.

        4.4    INVESTMENT OF FUNDS HELD AS SECURITY

               4.4.1    INVESTMENT

time to time as directed in writing by Lessee (or, if Lessee fails to so direct,
by or as directed by Lessor in its sole discretion) and at the expense and risk
of Lessee in Cash Equivalents so long as such Cash Equivalents specified by
Lessee or Lessor, as the case may be, can be acquired by Lessor using its best
efforts; provided, that so long as the Lien of the Trust Indenture shall not

Lessee or any Permitted Sublessee subject to a lease, conditional sale, trust
indenture or other security agreement that Lessor, its successors and assigns
will not acquire or claim, as against such lessor, conditional seller, indenture

      (a) Lessee and Lessor agree that this Lease is, and shall be treated as, a
lease for U.S. federal income tax purposes of the Aircraft, Airframe, Engines
and Parts.

      (b) It is the intention of each of Lessee and Lessor that Lessor (and
Mortgagee as assignee of Lessor under the Trust Indenture) shall be entitled to

        5.2    STORAGE AND RELATED MATTERS

      If Lessor gives written notice to Lessee not less than 60 days nor more
than 120 days prior to the end of the Term requesting storage of the Aircraft
upon its return hereunder, Lessee will provide Lessor, or cause Lessor to be
provided, with outdoor parking facilities for the Aircraft for a period up to 30
days, commencing on the date of such return, and upon request of Lessor to
Lessee made at least 10 days prior to the end of such initial 30 day period, for

(if available) for the Aircraft during such storage period, PROVIDED that Lessor
shall reimburse Lessee for Lessee's out-of-pocket cost of providing such
insurance. Such storage shall be at Lessor's risk, and Lessor shall pay all
applicable storage fees, except that Lessee shall pay the parking fees for the
initial 30 day storage period; PROVIDED that Lessee's obligation to provide
parking shall be subject to Lessor entering into an agreement prior to the
commencement of the storage period with the storage facility providing, among
other things, that Lessor shall bear all maintenance charges and other costs
(other than parking fees for the initial 30 day period) incurred.

      Upon the return of the Airframe upon any termination of this Lease, Lessor
shall pay Lessee, as compensation for any fuel or oil contained in the fuel or
oil tanks of such Airframe, the value of such fuel or oil at the price paid by
Lessee for such fuel or oil, PROVIDED that if the Aircraft is being returned in
connection with the exercise of remedies pursuant to Section 15, Lessor shall
have no obligation to make such payment to Lessee until Lessor shall have been
paid all amounts due to it pursuant to Section 15.

SECTION 6.     LIENS

      Lessee shall not, directly or indirectly, create, incur, assume or suffer

federal tax law consolidated group) for which Lessee is obligated to indemnify
such Tax Indemnitee under any of the Lessee Operative Agreements, in any such
case either not yet due or being contested in good faith by appropriate

material risk of the sale, forfeiture or loss of the Aircraft, the Airframe, any
Engine or the interest of any Participant therein or impair the lien of the
Trust Indenture; (e) materialmen's, mechanics', workers', repairers', employees'
or other like Liens arising in the ordinary course of business for amounts the
payment of which is either not yet delinquent for more than 60 days or is being

<PAGE>

contested in good faith by appropriate proceedings, so long as such Liens and
such proceedings do not involve any material risk of the sale, forfeiture or
loss of the Aircraft, the Airframe, any Engine or the interest of any
Participant therein or impair the lien of the Trust Indenture; (f) Liens arising
out of any judgment or award against Lessee (or against any Permitted
Sublessee), so long as such judgment shall, within 60 days after the entry
thereof, have been discharged or vacated, or execution thereof stayed pending
appeal or shall have been discharged, vacated or reversed within 60 days after
the expiration of such stay, and so long as during any such 60-day period there

such action as may be necessary duly to discharge (by bonding or otherwise) any
Lien not excepted above if the same shall at any time arise in respect of the
Aircraft, the Airframe, any Engine or any Part during the Term.

SECTION 7.     REGISTRATION, OPERATION, POSSESSION, SUBLEASING
               AND RECORDS

        7.1    REGISTRATION AND OPERATION

               7.1.1    REGISTRATION AND RECORDATION

      Subject to the compliance by Lessor and Owner Participant with their
respective obligations under Section 13 of the Participation Agreement, Lessee
shall cause the Aircraft to be, and at all times during the Term to remain, duly
registered with the FAA under the Act or with such other country of registry as
shall be permitted under Section 7.1.2 below, in the name of Lessor as owner and
lessor (except to the extent that such registration under the Act cannot be
effected with the FAA because of Lessor's or Owner Participant's failure to
comply with the citizenship requirements for registration of the Aircraft under
the Act). Lessor shall execute and deliver all such documents as Lessee (or any
Permitted Sublessee) may reasonably request for the purpose of effecting and
continuing such registration. Unless Mortgagee has given Lessee notice that the
Trust Indenture has been discharged, Lessee shall also cause the Trust Indenture
to be duly recorded and at all times maintained of record as a first-priority

<PAGE>

perfected mortgage (subject to Permitted Liens) on the Aircraft, the Airframe
and each of the Engines (except to the extent such perfection or priority cannot
be maintained solely as a result of the failure by Lessor or Mortgagee to
execute and deliver any necessary documents).

               7.1.2    REREGISTRATION

      So long as no Lease Event of Default shall have occurred and be
continuing, Lessee may, by written notice to Lessor, request to change the
country of registration of the Aircraft. Any such change in registration shall
be effected only in compliance with, and subject to all of the conditions set
forth in, Section 7.6.11 of the Participation Agreement.

               7.1.3    MARKINGS

      If permitted by applicable Law, on or reasonably promptly after the
Delivery Date, Lessee will cause to be affixed to, and maintained in, the
cockpit of the Airframe and on each Engine, in each case, in a clearly visible
location (it being understood that the location of such placards, as identified
to the Owner Participant prior to the Delivery Date, shall be deemed to be in
compliance with this requirement), a placard of a reasonable size and shape
bearing the legend, in English, set forth in Schedule 6. Such placards may be
removed temporarily, if necessary, in the course of maintenance of the Airframe
or Engines. If any such placard is damaged or becomes illegible, Lessee shall
promptly replace it with a placard complying with the requirements of this
Section 7.1.3.

               7.1.4    COMPLIANCE WITH LAWS

      Lessee shall not, and shall not allow any other person to, operate, use,
maintain, service, repair or overhaul the Aircraft (a) in violation of any Law
binding on or applicable to the Aircraft, the Airframe or any Engine, or (b) in
violation of any airworthiness certificate, license or registration of any
Government Entity relating to the Aircraft, the Airframe or any Engine, except
(1) immaterial or non-recurring violations with respect to which corrective
measures are taken promptly by Lessee or a Permitted Sublessee, as the case may
be, upon discovery thereof, and (2) to the extent Lessee or any Permitted
Sublessee is contesting the validity or application of any such Law or
requirement relating to any such certificate, license or registration in good
faith in any reasonable manner which does not involve any material risk of the
sale, forfeiture or loss of the Aircraft, the Airframe, any Engine or the

<PAGE>

interest of any Participant therein, any material risk of criminal liability or
of material civil penalty against Lessor, Mortgagee or any Participant or impair
the lien of the Trust Indenture.

               7.1.5    OPERATION

      Lessee agrees not to operate, use or locate the Aircraft, the Airframe or
any Engine, or allow the Aircraft, the Airframe or any Engine to be operated,
used or located (a) in any area excluded from coverage by any insurance required
by the terms of Section 11, except in the case of a requisition by the U.S.
Government where Lessee obtains an indemnity in lieu of such insurance from the
U.S. Government, or insurance from the U.S. Government, covering such area, in
accordance with Section 11.3 or (b) in any recognized area of hostilities unless
fully covered in accordance with Annex D by war-risk insurance as required by
the terms of Section 11 (including, without limitation, Section 11.3), unless in
any case referred to in this Section 7.1.5 the Aircraft is only temporarily
operated, used or located in such area as a result of an emergency, equipment
malfunction, navigational error, hijacking, weather condition or other similar
unforeseen circumstances, so long as Lessee diligently and in good faith
proceeds to remove the Aircraft from such area.

        7.2    POSSESSION

      Lessee will not, without the prior written consent of Lessor, sublease or
otherwise in any manner deliver, transfer or relinquish possession of the

Sublessee, as the case may be, in the ordinary course of business; PROVIDED,
HOWEVER, that if Lessor's title to any such Engine is divested under any such
agreement or arrangement, then such Engine shall be deemed to have suffered an
Event of Loss as of the date of such divestiture, with the effect that Lessee

requirements of, and in accordance with, Section 10.

               7.2.2    TESTING AND SERVICE

Aircraft, Airframe, any Engine or any Part (i) to the manufacturer thereof or to
any third-party maintenance provider, for testing, service, repair, maintenance
or overhaul work on the Aircraft, Airframe, any Engine or any Part, or, to the
extent required or permitted by the terms of Annex C, for alterations or
modifications in or additions to the Aircraft, Airframe or any Engine or (ii) to

to the Engines and (b) the rights of third parties under normal interchange or
pooling agreements and arrangements of the type that would be permitted under
Section 7.2.1.

               7.2.5    INSTALLATION OF ENGINES ON OTHER AIRFRAMES

      Install or permit any Permitted Sublessee to install an Engine on an
airframe leased to Lessee or such Permitted Sublessee, or purchased by Lessee or
such Permitted Sublessee subject to a mortgage, security agreement, conditional
sale or other secured financing arrangement, but only if (a) such airframe is
free and clear of all Liens, except (i) the rights of the parties to such lease,

<PAGE>

or any such secured financing arrangement, covering such airframe and (ii) Liens
of the type permitted by clauses (a) and (b) of Section 7.2.4 and (b) Lessee or
Permitted Sublessee, as the case may be, shall have received from the lessor,

Lessee shall comply with Section 10.2 hereof in respect thereof.

               7.2.7    SUBLEASING

      With respect to the Aircraft, Airframe or any Engine, so long as no Lease
Event of Default shall have occurred and is continuing, enter into a sublease

the United States maintains diplomatic relations with the country of domicile of
such Permitted Foreign Air Carrier (or, in the case of Taiwan, diplomatic
relations at least as good as those in effect on the Delivery Date) and (2)
Lessee shall have furnished Lessor and Mortgagee a favorable opinion of counsel,
reasonably satisfactory to Lessor, in the country of domicile of such Permitted
Foreign Air Carrier, that (i) the terms of such sublease are the legal, valid
and binding obligations of the parties thereto enforceable under the laws of
such jurisdiction, (ii) it is not necessary for Owner Participant, Lessor or
Mortgagee to register or qualify to do business in such jurisdiction, if not
already so registered or qualified, as a result, in whole or in part, of the
proposed sublease, (iii) Lessor's title to, and Mortgagee's Lien in respect of,
the Aircraft, Airframe and Engines will be recognized in such jurisdiction, (iv)
the Laws of such jurisdiction of domicile require fair compensation by the

      (g) Lessee shall reimburse Lessor, Mortgagee and Owner Participant for all
of their reasonable out-of-pocket fees and expenses, including, without
limitation, reasonable fees and disbursements of counsel, incurred by Lessor,
Mortgagee and Owner Participant in connection with any such sublease; and

      (h) No such sublease shall be made to a Permitted Foreign Air Carrier
prior to the close of the Tax Attribute Period, unless Lessee prepays on a
lump-sum basis any liability due under the Tax Indemnity Agreement as a result
of such sublease based upon the assumption that such sublease were to continue
for the remainder of the term of such sublease.

        7.3    CERTAIN LIMITATIONS ON SUBLEASING OR OTHER
               RELINQUISHMENT OF POSSESSION

of a Lease Event of Default;

      (b) Lessee shall remain primarily liable hereunder for the performance of
all the terms of this Lease to the same extent as if such transfer had not

obligations to Lessor hereunder or under any Operative Agreement;

      (c) Lessee shall ensure that no sublease, delivery, transfer or
relinquishment permitted under Section 7.2 shall affect the United States
registration of the Aircraft, unless also made in accordance with the provisions
of Section 7.1.2;

      (d) Any event that constitutes or would, with the passage of time,
constitute an Event of Loss under paragraph (c), (d), or (e) of the definition

<PAGE>

of such term (as set forth in Annex A) shall not be deemed to violate the
provisions of Section 7.2; and

      (e) Any Wet Lease shall not constitute a delivery, transfer or
relinquishment of possession for purposes of Section 7.2 and shall not be
prohibited by the terms hereof.

SECTION 8.     MAINTENANCE; REPLACEMENT AND POOLING OF PARTS;

               10.1.3   REPLACEMENT OF AIRFRAME AND ENGINES

      (a) If Lessee elects, in accordance with Section 10.1.1, to replace the

clear of all Liens other than Permitted Liens. If Lessee makes such election,
but for any reason fails or is unable to effect such replacement within such
time period and in compliance with the requirements set forth in Section 10.3,
then Lessee shall be deemed to have initially made the election set forth in
Section 10.1.2 with the effect that Lessee shall immediately pay, in the manner
and in funds of the type specified in Section 3.3, the amounts required under,
and in accordance with, Section 10.1.2.

      (b) Any such Replacement Airframe shall be an airframe that is the same
model as the Airframe to be replaced thereby, or an improved model, and that has
a value, utility and remaining useful life (without regard to hours or cycles
remaining until the next regular maintenance check), at least equal to the
Airframe to be replaced thereby (assuming that such Airframe had been maintained
in accordance with the Lease). Any such Replacement Engine shall meet the
requirements of, and be conveyed by Lessee to Lessor in accordance with, Section
10.2 (other than the notice requirement set forth in Section 10.2.1).

               10.2.1   NOTICE

               10.2.2   REPLACEMENT OF ENGINE

      Lessee shall, promptly and in any event within 60 days after the

which any Event of Loss occurred, title to a Replacement Engine free and clear

<PAGE>

of all Liens other than Permitted Liens. Such Replacement Engine shall be an
engine manufactured by Engine Manufacturer that is the same model as the Engine
to be replaced thereby, or an improved model, and that is suitable for
installation and use on the Airframe, and that has a value, utility and
remaining useful life (without regard to hours and cycles remaining until
overhaul) at least equal to the Engine to be replaced thereby (assuming that
such Engine had been maintained in accordance with the Lease).

               10.2.3   ENGINE EXCHANGE

      Upon not less than five (5) Business Days' prior written notice to Lessor,
Lessee may replace any Engine leased hereunder with another engine (the
"Exchanged Engine") meeting the requirements of Section 10.2.2. Such Exchanged
Engine shall be deemed to be a "Replacement Engine" and Lessor and Lessee shall
comply with the provisions of Section 10.3 with regard to the Exchanged Engine
and the Engine so replaced.

        10.3   CONDITIONS TO ANY REPLACEMENT

               10.3.1   DOCUMENTS

      Prior to or at the time of conveyance of title to any Replacement Airframe
or Replacement Engine to Lessor, Lessee shall take each of the following
actions:

      (a) furnish Lessor with a full warranty bill of sale duly conveying to
Lessor such Replacement Airframe or Replacement Engine, in form and substance
reasonably satisfactory to Lessor and cause such Replacement Airframe to be duly
registered in the name of Lessor pursuant to the Act;

      (b) cause (i) a Lease Supplement subjecting such Replacement Airframe or
Replacement Engine to this Lease, duly executed by Lessee, to be delivered to
Lessor for execution and, upon such execution, to be filed for recordation with
the FAA pursuant to the Act, (ii) a Trust Indenture Supplement, subjecting such
Replacement Airframe or Replacement Engine to the Trust Indenture, to be
delivered to Lessor for execution and, upon execution, to be filed for
recordation with the FAA pursuant to the Act and (iii) such Financing Statements
and other filings, as Lessor or Mortgagee may reasonably request, duly executed
by Lessee and, to the extent applicable, Lessor and Mortgagee (and Lessor and
Mortgagee shall execute and deliver the same), to be filed in such locations as
any such party may reasonably request;

<PAGE>

      (c) furnish such evidence of compliance with the insurance provisions of
Section 11 with respect to such Replacement Airframe or Replacement Engine as
Lessor may reasonably request;

      (d) furnish an opinion or opinions of Lessee's counsel (which may be
Lessee's legal department) reasonably satisfactory to Lessor and addressed to
Lessor and Mortgagee to the effect that (i) such full warranty bill of sale
referred to in Section 10.3.1(a) constitutes an effective instrument for the
conveyance of title to the Replacement Airframe or Replacement Engine and (ii)
in the case of a Replacement Airframe, Lessor and Mortgagee, as assignee of
Lessor, will be entitled to the benefits of Section 1110 with respect to the
Replacement Airframe, provided that such opinion referred to in this clause (ii)
need not be delivered to the extent that immediately prior to such replacement
the benefits of Section 1110 were not, solely by reason of a change in law or
court interpretation thereof, available to Lessor or Mortgagee, as assignee of
Lessor;

      (e) furnish an opinion of Lessee's aviation law counsel reasonably
satisfactory to Lessor and addressed to Lessor and Mortgagee as to the due
registration of any such Replacement Airframe and the due filing for recordation
of each Lease Supplement and Trust Indenture Supplement with respect to such
Replacement Airframe or Replacement Engine under the Act; and

      (f) with respect to the replacement of the Airframe, and any Engine
installed thereon at the time of the subject Event of Loss, if requested by
Lessor and at Lessor's expense, furnish a certified report of a qualified
independent aircraft appraiser, reasonably satisfactory to Lessor, certifying
that such Replacement Airframe and any such Replacement Engine complies with the
value, utility and remaining useful life requirements set forth in Section
10.1.3(b).

      Lessor and Lessee understand and agree that if at the time of any
replacement of the Airframe or any Engine, as contemplated in this Section 10,
the Airframe was registered in a jurisdiction other than the United States, then
the requirements set forth above in this Section 10.3.1 relating to compliance
with the requirements of the Act or the FAA, shall be deemed to refer to the
comparable applicable Law of, and the Aviation Authority of, such other
jurisdiction.

<PAGE>

               10.3.2   OTHER OBLIGATIONS

      (a) Lessor and Lessee agree that, upon any Replacement Airframe becoming
the Airframe hereunder, and upon any Replacement Engine becoming an Engine
hereunder, this Lease shall continue to be, and shall be treated as, a lease for
U.S. federal income tax purposes of, among other things, such Replacement
Airframe and such Replacement Engine. Without limiting the foregoing, Lessee and
Lessor intend that Lessor shall, in all events, be entitled to the benefits of
Section 1110 with respect to any Replacement Airframe or Replacement Engine and
Lessee and Lessor shall cooperate and take such action as the other may
reasonably request so as to ensure that Lessor shall be entitled to such
benefits.

      (b) No Event of Loss with respect to an Engine, or with respect to an
Airframe, shall result in, or otherwise allow or permit (other than as provided
in Section 10.1.2(b)), any reduction, deferral, discharge or other change in the
timing or amount of any Rent payable by Lessee hereunder, and (subject to such
Section 10.1.2(b)) Lessee shall pay all such Rent and other amounts as though
such Event of Loss had not occurred.

        10.4   CONVEYANCE TO LESSEE

      Upon compliance by Lessee with the applicable terms of Sections 10.1.3,
10.2 and 10.3.1, Lessor will transfer to Lessee the Airframe or Engine, as the
case may be, with respect to which such Event of Loss occurred, in accordance
with Section 4.5.

        10.5   APPLICATION OF PAYMENTS

      Any amounts, other than insurance proceeds in respect of damage or loss
not constituting an Event of Loss (the application of which is provided for in
Section 11), received at any time by Lessor, Lessee or any Permitted Sublessee
from any Government Entity or any other Person in respect of any Event of Loss
will be applied as follows:

               10.5.1   REPLACEMENT OF AIRFRAME AND ENGINES

      If such amounts are received with respect to the Airframe, and any Engine
installed thereon at the time of such Event of Loss, upon compliance by Lessee
with the applicable terms of Section 10.1.3 with respect to the Event of Loss
for which such amounts are received, such amounts shall be paid over to, or
retained by, Lessee.

<PAGE>

               10.5.2   LOSS OF ENGINE

      If such amounts are received with respect to an Engine (other than an
Engine installed on the Airframe at the time such Airframe suffers an Event of
Loss), upon compliance by Lessee with the applicable terms of Section 10.2.2
with respect to the Event of Loss for which such amounts are received, such
amounts shall be paid over to, or retained by, Lessee.

               10.5.3   PAYMENT OF LOSS

      If such amounts are received, in whole or in part, with respect to the
Airframe, and Lessee makes, has made or is deemed to have made the election set
forth in Section 10.1.2, such amounts shall be applied as follows:

      (a) FIRST, if the sum described in Section 10.1.2 has not then been paid
in full by Lessee, such amounts shall be paid to Lessor (or to Mortgagee so long
as Mortgagee has not given notice to Lessee that the Lien of the Trust Indenture
has been duly discharged, except with respect to Excluded Payments) to the
extent necessary to pay in full such sum;

      (b) SECOND, the remainder, if any, shall be paid to Lessee.

        10.6   REQUISITION OF AIRCRAFT FOR USE

      If any Government Entity shall requisition for use the Airframe and the
Engines or engines installed thereon, and if the same does not constitute an
Event of Loss, Lessee shall promptly notify Lessor and Mortgagee of such
requisition and all of Lessee's obligations under this Agreement shall continue
to the same extent as if such requisition had not occurred; PROVIDED, HOWEVER,
that if the Airframe and Engines or engines installed thereon are not returned
to Lessor by Lessee at the end of the Term or within 30 days thereafter, and
Lessor, upon notice given not less than 30 days nor more than 120 days before
the end of the Term, shall have elected to treat such event as constituting an
Event of Loss with respect to the Aircraft, Lessee shall then be deemed to have
made the election set forth in Section 10.1.2 with the effect that Lessee shall
be obligated to pay the Stipulated Loss Value and all other amounts payable
pursuant to Section 10.1.2 with respect to the Aircraft as if an Event of Loss
had occurred as of the end of the Term. If Lessor shall not have elected to
treat such event as an Event of Loss, Lessee shall be obligated to return the
Airframe and Engines or engines to Lessor pursuant to, and in all other respects

<PAGE>

to comply with the provisions of, Section 5 promptly upon their return by such
Government Entity, and Lessee shall pay to Lessor upon such return an amount

day after the end of the Term to but excluding the day of such return, up to a
maximum of 30 days.

        10.7   REQUISITION OF AN ENGINE FOR USE

      If any Government Entity shall requisition for use any Engine but not the
Airframe, Lessee will replace such Engine by complying with the applicable terms
of Sections 10.2 and 10.3 to the same extent as if an Event of Loss had occurred
with respect to such Engine, and any payments received by Lessor or Lessee from
such Government Entity with respect to such requisition shall be paid or
retained in accordance with Section 10.5.2.

        10.8   APPLICATION OF PAYMENTS

      All payments received by Lessor or Lessee, or any Permitted Sublessee,
from any Government Entity for the use of the Airframe and Engines or engines
installed thereon during the Term shall be paid over to, or retained by, Lessee
and all payments received by Lessor or Lessee from any Government Entity for the
use of the Airframe and Engines or engines installed thereon after the Term
shall be paid over to, or retained by, Lessor; provided that, if such
requisition constitutes an Event of Loss, or Lessor has elected under Section
10.6 to treat such requisition as an Event of Loss, then all such payments shall
be paid over to Lessor (or to Mortgagee so long as Mortgagee has not given
notice to Lessee that the Lien of the Trust Indenture has been duly discharged),
and held as provided in Section 10.5.

        10.9   APPLICATION OF PAYMENTS DURING EXISTENCE OF A
               LEASE EVENT OF DEFAULT

      Any amount described in this Section 10 that is payable or creditable to,
or retainable by, Lessee shall not be paid or credited to, or retained by,
Lessee if at the time such payment, credit or retention would otherwise occur a
Special Default or Lease Event of Default shall have occurred and be continuing,
but shall instead be held by or paid over to Lessor (or to Mortgagee so long as
Mortgagee has not given notice to Lessee that the Trust Indenture has been duly
discharged) as security for the obligations of Lessee under this Lease and the
other Lessee Operative Agreements and shall be invested pursuant to Section 4.4
hereof unless and until Lessor shall have demanded liquidated damages pursuant

<PAGE>

to Section 15.1.3 or 15.1.4 and such amount is applied, at the option of Lessor,
or upon the written request of Lessee to Lessor, from time to time during the
continuance of a Lease Event of Default, to Lessee's obligations under this
Lease as and when due, it being understood that any such application shall be
made to such obligations of Lessee as Lessor may determine in its sole
discretion. At such time as there shall not be continuing any Special Default or
Lease Event of Default, such amount shall be paid to Lessee to the extent not
previously applied in accordance with this Section 10.9.

SECTION 11.    INSURANCE

        11.1   LESSEE'S OBLIGATION TO INSURE

      Lessee shall comply with, or cause to be complied with, each of the
provisions of Annex D, which provisions are hereby incorporated by this

      Nothing in Section 11 shall limit or prohibit (a) Lessee from maintaining
the policies of insurance required under Annex D with higher limits than those
specified in Annex D, or (b) Lessor, Mortgagee or Owner Participant from
obtaining insurance for its own account (and any proceeds payable under such
separate insurance shall be payable as provided in the policy relating thereto);
PROVIDED, HOWEVER, that no insurance may be obtained or maintained that would
limit or otherwise adversely affect the coverage of any insurance required to be
obtained or maintained by Lessee pursuant to this Section 11 and Annex D.

               INSURANCE

respect to the Aircraft described in Annex D, indemnification from, or insurance
provided by, the U.S. Government, or upon the written consent of Lessor, other

of insurance (including permitted self-insurance), if any, against such risk
that Lessee (or any Permitted Sublessee) may continue to maintain, in accordance
with this Section 11, during the period of such requisition or transfer, shall
be at least equal to the amount of insurance against such risk otherwise
required by this Section 11.

will be applied in accordance with Section 10.5. All proceeds of insurance
required to be maintained by Lessee, in accordance with Section 11 and Section B
of Annex D, in respect of any property damage or loss not constituting an Event
of Loss with respect to the Aircraft, Airframe or any Engine will be applied in
payment (or to reimburse Lessee) for repairs or for replacement property, and
any balance remaining after such repairs or replacement with respect to such
damage or loss shall be paid over to, or retained by, Lessee.

               EVENT OF DEFAULT

      Any amount described in this Section 11 that is payable or creditable to,
or retainable by, Lessee shall not be paid or credited to, or retained by,
Lessee if at the time such payment, credit or retention would otherwise occur a
Special Default or Lease Event of Default shall have occurred and be continuing,
but shall instead be held by or paid over to Lessor (or to Mortgagee so long as
Mortgagee has not given notice to Lessee that the Lien of the Trust Indenture
has been duly discharged) as security for the obligations of Lessee under this
Lease and shall be invested pursuant to Section 4.4 hereof unless and until
Lessor shall have demanded liquidated damages pursuant to Section 15.1.3 or
15.1.4 and such amount is applied, at the option of Lessor, or upon the written
request of Lessee to Lessor, from time to time during the continuance of a Lease
Event of Default, to Lessee's obligations under this Lease and the other Lessee
Operative Agreements as and when due, it being understood that any such
application shall be made to such obligations of Lessee as Lessor may determine

to the extent not previously applied in accordance with this Section 11.5.

SECTION 12.    INSPECTION

      (a) At all reasonable times Lessor, Mortgagee or the Owner Participant,
and their respective authorized representatives (the "Inspecting Parties") may
(not more than once every 12 months unless a Lease Event of Default has occurred

<PAGE>

and is continuing then such inspection right shall not be so limited) inspect
the Aircraft, Airframe and Engines (including, without limitation, the Aircraft
Documents) and any such Inspecting Party may make copies of such Aircraft
Documents not reasonably deemed confidential by Lessee or such Permitted
Sublessee.

      (b) Any inspection of the Aircraft hereunder shall be limited to a visual,
walk-around inspection and shall not include the opening of any panels, bays or
other components of the Aircraft, and no such inspection shall interfere with
Lessee's or any Permitted Sublessee's maintenance and operation of the Aircraft,
Airframe and Engines.

      (c) With respect to such rights of inspection, Lessor, Owner Participant
and Mortgagee shall not have any duty or liability to make, or any duty or
liability by reason of not making, any such visit, inspection or survey.

      (d) Each Inspecting Party shall bear its own expenses in connection with
any such inspection (including the cost of any copies made in accordance with
Section 12(a)).

        13.1   IN GENERAL

and permitted assigns. Except as otherwise expressly permitted by the terms of
the Lease or any other Lessee Operative Agreement, Lessee will not, without the
prior written consent of Lessor and Mortgagee, assign any of its rights under
this Lease. Except as otherwise provided herein (including, without limitation,

      Lessee shall not consolidate with or merge into any other person under
circumstances in which Lessee is not the surviving corporation, or convey,
transfer or lease in one or more transactions all or substantially all of its
assets to any other person, unless:

<PAGE>

      (a) such person is organized, existing and in good standing under the Laws
of the United States, any State of the United States or the District Columbia
and, upon consummation of such transaction, such person will be a U.S. Air
Carrier;

      (b) such person executes and delivers to Lessor and Mortgagee a duly
authorized, legal, valid, binding and enforceable agreement, reasonably
satisfactory in form and substance to Lessor, containing an effective assumption
by such person of the due and punctual performance and observance of each
covenant, agreement and condition in the Lessee Operative Agreements to be
performed or observed by Lessee;

      (c) such person makes such filings and recordings with the FAA pursuant to
the Act as shall be necessary to evidence such consolidation or merger; and

      (d) immediately after giving effect to such consolidation or merger no
Lease Event of Default shall have occurred and be continuing.

               13.2.2   EFFECT OF MERGER

      Upon any such consolidation or merger of Lessee with or into, or the
conveyance, transfer or lease by Lessee of all or substantially all of its
assets to, any Person in accordance with this Section 13.2, such Person will
succeed to, and be substituted for, and may exercise every right and power of,
Lessee under the Lessee Operative Agreements with the same effect as if such
person had been named as "Lessee" therein. No such consolidation or merger, or
conveyance, transfer or lease, shall have the effect of releasing Lessee or such
Person from any of the obligations, liabilities, covenants or undertakings of
Lessee under the Lease.

        13.3   ASSIGNMENT SECURITY FOR LESSOR'S OBLIGATIONS

      In order to secure the indebtedness evidenced by the Equipment Notes,

of Mortgagee, subject to the reservations and conditions therein set forth.
Lessee hereby accepts and consents to the assignment of all Lessor's right,
title and interest in and to this Lease pursuant to the terms of the Trust
Indenture. In accordance with Section 3.3(c), Lessee agrees to pay directly to
Mortgagee (or, after receipt by Lessee of notice from Mortgagee of the discharge
of the Lien of the Trust Indenture, to Lessor), all amounts of Rent (other than

<PAGE>

Excluded Payments) due or to become due hereunder and assigned to Mortgagee and
Lessee agrees that Mortgagee's right to such payments hereunder shall be
absolute and unconditional and shall not be affected by any circumstance,
including, without limitation, the circumstances set forth in Section 16 hereof.
Notwithstanding the foregoing assignment of this Lease, the obligations of
Lessee to Lessor to perform the terms and conditions of this Lease shall remain
in full force and effect.

        13.4   SUCCESSOR OWNER TRUSTEE

      Lessee agrees that in the case of the appointment of any successor Owner
Trustee pursuant to the terms of the Participation Agreement and the Trust
Agreement, such successor Owner Trustee shall, upon written notice by such
successor Owner Trustee to Lessee, succeed to all the rights, powers and title
of Lessor hereunder and shall be deemed to be Lessor and the owner of the
Aircraft and the other assets of the Trust Estate for all purposes hereof
without the necessity of any consent or approval by Lessee and without in any
way altering the terms of this Lease or Lessee's obligations hereunder. An
appointment and designation of a successor Owner Trustee shall not exhaust the
right to appoint and designate further successor or additional Owner Trustees
pursuant to the Participation Agreement and the Trust Agreement, and such right
may be exercised repeatedly as long as this Lease shall be in effect.

SECTION 14.    LEASE EVENTS OF DEFAULT

      The occurrence of any one or more of the following circumstances,

occurrence of any Lease Event of Default or the exercise of Lessor's remedies
with respect thereto, including all reasonable costs and expenses incurred in
connection with the return of the Airframe or any Engine, in accordance with the
terms of Section 5 or in placing the Airframe or any Engine, in the condition
and airworthiness required by Section 5.

        15.2   LIMITATIONS UNDER CRAF

      Notwithstanding the provisions of Section 15.1, during any period that the
Aircraft, Airframe or any Engine is subject to CRAF in accordance with the
provisions of Section 7.2.3 and in the possession of the U.S. Government, Lessor
shall not, as a result of any Lease Event of Default, exercise its remedies
hereunder in such manner as to limit Lessee's control under this Lease (or any
Permitted Sublessee's control under any Permitted Sublease) of the Aircraft,
Airframe or such Engine, unless at least 30 days' (or such other period as may
then be applicable under CRAF) written notice of default hereunder shall have
been given by Lessor or Mortgagee by registered or certified mail to Lessee (and
any Permitted Sublessee) with a copy to the Contracting Officer Representative
or Representatives for the Military Airlift Command of the United States Air
Force to whom notices must be given under the contract governing Lessee's (or
any Permitted Sublessee's) participation in CRAF with respect to the Aircraft,
Airframe or any Engine.

        15.3   RIGHT TO PERFORM FOR LESSEE

      If Lessee (i) fails to make any payment of Rent required to be made by it
hereunder or (ii) fails to perform or comply with any of its agreements
contained herein and such failure continues for a period of thirty days after
written notice thereof is given by Lessor or Mortgagee to Lessee, Lessor or

<PAGE>

Mortgagee may (but shall not be obligated to) make such payment or perform or
comply with such agreement, and the amount of such payment and the amount of the
expenses of Lessor or Mortgagee incurred in connection with such payment or the
performance of or compliance with such agreement, as the case may be, together
with interest thereon at the Payment Due Rate, shall be deemed Supplemental
Rent, payable by Lessee upon demand by Lessor or Mortgagee, whichever is
entitled thereto. No such payment, performance or compliance shall be deemed to
cure any Lease Default or Lease Event of Default or otherwise relieve Lessee of
its obligations with respect thereto.

        15.4   DETERMINATION OF FAIR MARKET RENTAL VALUE AND
               FAIR MARKET SALES VALUE

      For the purpose of this Section 15, the "Fair Market Rental Value" or the
"Fair Market Sales Value" of the Aircraft, Airframe or any Engine, shall be
determined on an "as is, where is" basis and shall take into account customary
brokerage and other out-of-pocket fees and expenses which typically would be
incurred in connection with a re-lease or sale of the Aircraft, Airframe or any
Engine. Any such determination shall be made by an Appraiser selected by Lessor
and the costs and expenses associated therewith shall be borne by Lessee, unless
Lessor does not obtain possession of the Aircraft, Airframe and Engines pursuant
to this Section 15, in which case an Appraiser shall not be appointed and Fair
Market Rental Value and Fair Market Sales Value for purposes of this Section 15
shall be zero.

        15.5   REMEDIES CUMULATIVE

      Nothing contained in this Lease shall be construed to limit in any way any
right, power, remedy or privilege of Lessor hereunder or under any other
Operative Agreement or now or hereafter existing at law or in equity. Each and
every right, power, remedy and privilege hereby given to, or retained by, Lessor
in this Lease shall be in addition to and not in limitation of every other
right, power, remedy and privilege given under the Operative Agreements or now
or hereafter existing at law or in equity. Each and every right, power, remedy
and privilege of Lessor under this Lease and any other Operative Agreement may
be exercised from time to time or simultaneously and as often and in such order
as may be deemed expedient by Lessor. All such rights, powers, remedies and
privileges shall be cumulative and not mutually exclusive, and the exercise of
one shall not be deemed a waiver of the right to exercise any other. Lessee

<PAGE>

hereby waives to the extent permitted by applicable Law any right which it may
have to require Lessor to choose or elect remedies.

SECTION 16.    LESSEE'S OBLIGATIONS; NO SETOFF, COUNTERCLAIM,
               ETC.

      (a) Lessee's obligation to pay Rent hereunder shall be absolute and
unconditional, and shall not be affected by any event or circumstance,
including, without limitation: (i) any setoff, counterclaim, recoupment, defense
or other right that Lessee may have against Lessor, Mortgagee, any Participant,
any Note Holder, or any other Person for any reason whatsoever; (ii) any defect
in the title, airworthiness, condition, design, operation or fitness for use of,
or any damage to or loss or destruction of, the Aircraft, Airframe or any
Engine, or any interruption or cessation in the use or possession thereof by
Lessee for any reason whatsoever; (iii) any insolvency, bankruptcy,
reorganization or similar proceedings by or against Lessee or any other Person;
or (iv) any other circumstance, happening or event whatsoever, whether or not
similar to any of the foregoing.

      (b) If for any reason whatsoever this Lease shall be terminated in whole
or in part by operation of law or otherwise except as specifically provided
herein, Lessee nonetheless agrees to pay an amount equal to each Rent payment at
the time such payment would have become due and payable in accordance with the
terms hereof had this Agreement not been terminated in whole or in part. Lessee
hereby waives, to the extent permitted by applicable law, any and all rights
that it may now have or that at any time hereafter may be conferred upon it, by
statute or otherwise, to terminate, cancel, quit or surrender this Agreement,
except in accordance with the express terms hereof.

      (c) Nothing set forth in this Section 16 shall be construed to prohibit
Lessee from separately pursuing any claim that it may have from time to time
against Lessor or any other Person with respect to any matter (other than the
absolute and unconditional nature of Lessee's obligations hereunder to pay Rent,
and other than the matters specified in paragraphs (a) and (b) above).

SECTION 17.    RENEWAL AND PURCHASE OPTIONS

        17.1   NOTICES GENERALLY

      (a) At least 120 days prior to the Scheduled Expiration Date or, if a

<PAGE>

Expiration Date of such Renewal Lease Term, Lessee may provide notice to Lessor
that Lessee may exercise either the option to extend the leasing of the Aircraft
for a Renewal Lease Term pursuant to Section 17.2 or the option to purchase the
Aircraft on the Scheduled Expiration Date or Scheduled Renewal Term Expiration
Date of such Renewal Lease Term, as the case may be, pursuant to Section 17.3 (a
"Preliminary Notice").

      (b) If any such Preliminary Notice is given by Lessee, then Lessee may
provide a further notice specifying which option it intends to elect, with
respect to the relevant period, pursuant to Section 17.2.1 or 17.3.1, as the
case may be.

        17.2   RENEWAL OPTIONS

               17.2.1   RENEWAL NOTICE

      (a) If Lessee has given a Preliminary Notice, as specified in Section
17.1, and subject to the terms and conditions of this Section 17.2, Lessee may
exercise its option to extend the leasing of the Aircraft hereunder until the
next Scheduled Renewal Term Expiration Date, on the same terms, provisions and
conditions (except as contemplated by this Section 17) set forth herein and in
the other Lessee Operative Agreements with respect to the Base Lease Term, by
delivery of a notice (a "Renewal Notice") to Lessor not less than 90 days prior
to (i) if the Base Lease Term is then in effect, the Scheduled Expiration Date,
or (ii) if a Renewal Lease Term is then in effect, the Scheduled Renewal Term
Expiration Date for such Renewal Lease Term.

      (b) Notwithstanding anything to the contrary in this Agreement or any
other Operative Agreement:

            (i) No Preliminary Notice or Renewal Notice shall be binding on
      Lessor or oblige Lessor to extend the leasing of the Aircraft hereunder
      for a Renewal Lease Term if any Lease Event of Default shall have occurred
      and be continuing on and as of the date that such Renewal Lease Term would
      otherwise commence.

            (ii) Any Renewal Notice shall be revocable by Lessee until 10
      Business Days after the Renewal Rent is determined in accordance with
      Sections 17.2.2 and unless revoked by written notice by Lessee to Lessor
      shall thereafter become irrevocable and shall constitute an unconditional

<PAGE>

      obligation of Lessee to extend the leasing of the Aircraft hereunder for
      the Renewal Lease Term to which such Renewal Notice relates.

            (iii) Lessee shall not be entitled to give any Renewal Notice if it
      has (x) not delivered a Preliminary Notice or (y) delivered a Purchase
      Notice to Lessor.

               17.2.2   RENEWAL RENT

      (a) During the Renewal Lease Term, Lessee shall pay to Lessor on each
Payment Date, in the manner and in the funds of the type specified in Section
3.3, Renewal Rent in arrears.

      (b) The Renewal Rent payable by Lessee on each Payment Date during any
Fixed Renewal Lease Term shall be the lower of (i) the Renewal Rent Limit and
(ii) the Fair Market Rental Value of the Aircraft for such Renewal Lease Term.
The Renewal Rent payable by Lessee on each Payment Date during any Subsequent
Renewal Lease Term shall be the Fair Market Rental Value of the Aircraft for
such Renewal Lease Term. Any such Fair Market Rental Value shall be determined
not more than 120 days and not less than 100 days prior to the date of
commencement of such Renewal Lease Term by mutual agreement of Lessor and Lessee
or, if they shall be unable to agree, by an appraisal in accordance with Section
17.4. Notwithstanding the foregoing, (i) on the first Payment Date of a Renewal
Term, Lessee shall pay to Lessor a pro-rated amount of Renewal Rent equal to (x)
the Renewal Rent applicable to such Renewal Term divided by 180 multiplied by
(y) the actual number of days elapsed in such Payment Period and (ii) on the
last Payment Date in such Renewal Term Lessee shall pay to Lessor an amount
equal to the Renewal Rent minus the amount referred to in the preceding clause
(i).

               17.2.3   STIPULATED LOSS AND TERMINATION VALUES

      (a) For any Renewal Lease Term, Stipulated Loss Value Dates and
Termination Value Dates shall be extended throughout such Renewal Lease Term on
the same days and for the same months as during the Base Lease Term.

      (b) Stipulated Loss Value and Termination Value amounts that are payable
during any such Renewal Lease Term shall be determined at the same time that the
Renewal Rent for such Renewal Lease Term is determined under Section 17.2.2.
Stipulated Loss Values and Termination Values for any such Renewal Lease Term
shall, commencing on the first day of such Renewal Lease Term, be equal to the

<PAGE>

Fair Market Sales Value of the Aircraft, computed as of the first day of such
Renewal Lease Term, and shall decline ratably on a monthly basis to the Fair
Market Sales Value of the Aircraft as of the last day of such Renewal Lease
Term.

      (c) Any Fair Market Sales Value of the Aircraft, for purposes of
calculating Stipulated Loss Value and Termination Value amounts applicable
during any such Renewal Lease Term, shall be determined by mutual agreement of
Lessor and Lessee or, if they shall be unable to agree, by an appraisal in
accordance with Section 17.4.

        17.3   PURCHASE OPTION

               17.3.1   PURCHASE NOTICE

      (a) Subject to Section 17.1 and the terms and conditions of this Section
17.3, Lessee may elect to purchase the Aircraft, on any Purchase Date, at a
purchase price equal to the lesser of 50% of Lessor's Cost and the Fair Market
Sales Value of the Aircraft computed as of the Purchase Date.

      (b) Lessee may exercise such option to purchase the Aircraft, by delivery
of a notice (a "Purchase Notice") to Lessor not less than 90 days prior to the
Purchase Date specified in such Purchase Notice.

      (c) Notwithstanding anything to the contrary in this Agreement or any
other Operative Agreement:

            (i) Any Purchase Notice (whether delivered or deemed to have been
      delivered) shall be revocable until 10 Business Days after the
      determination of the Fair Market Sales Value in accordance with Section
      17.3.2 and unless revoked by written notice by Lessee to Lessor shall
      thereafter become irrevocable and shall constitute an unconditional
      obligation of Lessee to purchase the Aircraft under this Section 17.3.

            (ii) Lessee shall not be entitled to give any Purchase Notice in
      respect of any Purchase Date if it has delivered a Renewal Notice for a
      Renewal Lease Term that would commence immediately following such Purchase
      Date.

               17.3.2   DETERMINATION OF FAIR MARKET SALES VALUE

      The Fair Market Sales Value of the Aircraft shall be determined not more
than 120 days and not less than 100 days prior to the applicable Purchase Date

<PAGE>

by mutual agreement of Lessor and Lessee or, if they shall be unable to agree,
by an appraisal in accordance with Section 17.4.

               17.3.3   TITLE

      Upon full and final payment by Lessee of (a) the applicable purchase price
of the Aircraft, (b) all unpaid Rent due and payable through and including the
Purchase Date and (c) all other amounts due and payable by Lessee under this
Agreement, Lessor will transfer to Lessee title to the Aircraft in accordance
with Section 4.5.

        17.4   APPRAISALS

      Whenever Fair Market Rental Value or Fair Market Sales Value of the
Aircraft is required to be determined by an appraisal under this Section 17,
Lessee and Lessor shall appoint a mutually satisfactory Appraiser to conduct
such appraisal. If Lessee and Lessor fail to agree upon a satisfactory Appraiser
then each shall promptly appoint a separate Appraiser and such Appraisers shall
jointly determine such amount. If either Lessee or Lessor fails to so appoint an
Appraiser, the determination of the single Appraiser appointed shall be final.
If two Appraisers are appointed and within 7 days after the appointment of the
latter of such two Appraisers, they cannot agree upon such amount, such two
Appraisers shall, within 8 days after such latter appointment, appoint a third
Appraiser and such amount shall be determined by such three Appraisers, who
shall make their separate appraisals within 7 days following the appointment of
the third Appraiser, and any determination so made shall be conclusive and
binding upon Lessor and Lessee. If no such third Appraiser is appointed within
such 8-day period, either Lessor or Lessee may apply to the American Arbitration
Association to make such appointment, and both parties shall be bound by such
appointment. The foregoing appraisal procedure shall in any event be completed
no less than 125 days before the end of the Base Lease Term or the current
Renewal Lease Term, as the case may be. If three Appraisers are appointed and
the difference between the determination which is farther from the middle
determination and the middle determination is more than 125% of the difference
between the middle determination and the third determination, then such farther
determination shall be excluded, the remaining two determinations shall be
averaged and such average shall be final and binding upon Lessor and Lessee.
Otherwise, the average of all three determinations shall be final and binding
upon Lessor and Lessee. The fees and expenses of all such Appraisers and such
appraisal procedure shall be borne equally by Lessee and Lessor, PROVIDED that

<PAGE>

if Lessee elects not to renew this Lease or purchase the Aircraft following the
conclusion of such appraisal, Lessee shall pay all expenses of such appraisal.

      Lessor and Lessee have heretofore entered into that certain Lease

incorporated by reference in the Lease to the same extent as if fully set forth
therein.

      6. This Lease Supplement may be executed by the parties hereto in separate
counterparts, each of which when so executed and delivered shall be an original,
but all such counterparts shall together constitute but one and the same
instrument.

      7. To the extent, if any, that this Lease Supplement constitutes chattel

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, which shall be identified as the counterpart

                           PURCHASE AND SALE AGREEMENT

1.   ASSIGNEMENT. Prestige Capital Corporation ("Prestige") hereby buys and

     ("Seller") hereby sells, transfers and assigns all of Seller's right, title
     and interest in and to those specific accounts receivable owing to Seller
     as set forth on the assignment forms provided by Prestige (the
     "Assignments") together with all rights of action accrued or to accrue
     thereon, including without limitation, full power to collect, sue for,
     compromise, assign or in any other manner enforce collection thereof in
     Prestige's name or otherwise. (All of Seller's accounts receivable and
     contract rights which are presently or at any time hereafter assigned by
     Seller, and accepted by Prestige, are collectively referred to as the
     "Accounts".)

2.   DISCOUNT. Prestige's purchase of the Accounts from Seller is at a discount
     fee of TEN percent (10 %) from the face value of each Account.

3.   RESERVE. Upon Prestige's receipt and acceptance of each Assignment,
     Prestige shall pay to Seller SEVENTY-FIVE percent (75 %) of the net face
     value of the Accounts therein described (the "Down Payment"). Prestige will
     hold in reserve the difference between the Purchase Price (hereinafter
     defined) and the Down Payment (the "Reserve") and will pay to Seller the
     Reserve, less any sums due Prestige hereunder, on the Friday following the
     week in which all Accounts set forth on the applicable Assignment have been
     collected in good funds, charged back and/or deemed collected by Prestige
     due to an account debtor's (hereinafter defined) insolvency. For purpose of
     this Agreement, the term "Purchase Price" shall mean the net face value of
     Accounts, less: Prestige's discount fee described in paragraph 2 above;
     returns, credits, allowances and discounts on the shortest or, at
     Prestige's option, on alternative terms of sale offered by Seller to
     account debtors; and less all other sums charged or chargeable to Seller's
     accounts.

4.   REBATES. As on inducement to Seller to facilitate the prompt payment of the
     Accounts from Seller's customers ("account debtor"), Prestige agrees to
     return to Seller a rebate of SIX & 1/4 percent (6.25 %) if the Accounts are
     paid to Prestige within 30 days, a rebate of FIVE & 1/4 percent (5.25 %) if
     the Accounts are paid to Prestige within 45 days, a rebate of FOUR & 1/4
     percent (4.25 %) if the Accounts are paid to Prestige within 60 days, a
     rebate of TWO & 1/4 percent (2.25 %) if the Accounts are paid to Prestige
     within 90 days.

5.   WARRANTIES, REPRESENTATIONS AND COVENANTS. As an inducement for Prestige's
     entering into this Agreement and with full knowledge that the truth and
     accuracy of the warranties, representations and covenants in this Agreement
     are being relied upon by Prestige instead of the delay of a complete credit
     investigation, Seller warrants, represents and covenants that:

         (a) Seller is properly licensed and authorized to operate the business
             of software development;

             offset of counterclaim and which is due and payable in ninety days
             or less;
         (e) Each Account is an accurate statement of a bona fide sale, delivery
             and acceptance of merchandise or performance of service by Seller
             to an account debtor;
         (f) Seller does not own, control or exercise dominion in any way
             whatsoever, over the business of any account debtor;
         (g) All financial records, statements, books or other documents shown
             to Prestige by Seller at any time either before or after the
             signing of this Agreement are true and accurate;
         (h) Seller will not under any circumstance or in any manner whatsoever,
             interfere with any of prestige's rights under this Agreement;
         (i) Seller has not and will not, at any time, permit any lien, security
             interest or encumbrance to be created upon any of its accounts
             receivable and/or its inventory without the prior written consent
             of Prestige;
         (j) Seller will not change or modify the terms of the Accounts with any
             account debtor unless Prestige first consents in writing;
         (k) Seller will notify Prestige in writing in advance of: any change in
             Seller's place of business; Seller having or acquiring more than
             one place of business; any change in Seller's chief executive
             officer; and/or any change in the office or offices where Seller's
             books and records concerning accounts receivable are kept;
         (l) Seller will immediately notify Prestige of any proposed or actual
             change of the Seller's and/or any account debtor's identity, legal
             entity or corporate structure.
         (m) All invoices will state plainly on their face that the Accounts
             represented thereby have been sold and assigned to Prestige and are
             payable only and directly to Prestige; and
         (n) No Account shall be on a bill-and-hold, guaranteed sale,
             sale-and-return, sale on approval, consignment or any other
             repurchase or return basis.

         The warranties, representations and covenants contained in this
         paragraph 5 shall be continuous and be deemed to be renewed each time
         Seller assigns Accounts to Prestige. Notwithstanding the provisions
         contained in paragraph 6 of this Agreement, Prestige shall have
         recourse against the Seller in the event that any of the warranties,
         representations and covenants set forth in this paragraph 5 are
         breached.

6.   NO RECOURSE. Prestige shall have recourse against Seller in all instances
     except if payments are not received due to the "Insolvency" of an account
     debtor within 120 days of invoice date. For purposes of the foregoing,
     Insolvency shall be deemed to have occurred only when: (a) a voluntary or
     involuntary bankruptcy proceeding for the relief of an account debtor under
     either Chapter 7 or Chapter 11 shall have instituted in a United States
     Bankruptcy Court; (b) a receiver is appointed for the whole or any part of
     the property of an account debtor; (c) an account debtor's assets shall
     have been sold under a writ of execution or attachments, or a writ of
     execution shall have been returned unsatisfied; (d) an account debtor shall
     have absconded; or (e) an account debtor's assets shall have been sold
     under levy by any taxing authority or by a landlord.

7.   CHARGE-BACK. In the event that any Account is not paid within 100 days of
     invoice date for any reason whatsoever (other than as a result of a account
     debtor's Insolvency). Including, without limitation, any alleged defense,
     counterclaim, offset, dispute or other claim (real or merely asserted)
     whether arising from or relating to the sale of goods or rendition of
     services or arising from or relating to any other transaction or
     occurrence, then in any such event Prestige shall have the right to
     chargeback such Account to Seller. No chargeback shall be deemed a
     reassignment to Seller of the Account involved. Seller acknowledges that
     all amounts chargeable to Seller's account under this Agreement shall be
     payable by Seller on demand.

8.   NOTICE OF DISPUTE. Seller must immediately notify Prestige of any disputes
     between any account debtor and Seller.

9.   SETTLEMENT OF DISPUTE. Prestige may, at its option, settle any dispute with
     any account debtor. Such settlement does not relieve Seller of any of its
     obligations under this Agreement.

10.  SOLE PROPERTY. Once Prestige has purchased the Accounts, the payment from
     account debtors relative to the Accounts is the sole property of Prestige.
     Any interference by Seller with this payment will result in civil and/or
     criminal liability.

11.  SECURITY INTEREST. As a further inducement for Prestige to enter into this
     Agreement, and as security for the prompt performance, observance and
     payment of all obligations owing by Seller to Prestige herein, Seller
     hereby grants to Prestige a continuing security interest in and lien upon
     the following (herein collectively referred to as the "Collateral"): all
     accounts, instruments, documents, chattel paper and general intangibles (as
     such terms are defined in the Uniform Commercial Code), whether now owned
     or hereafter created or acquired by Seller, wherever located, and all
     replacements and substitutions therefore, accessions thereto, and products
     and proceeds thereof, and all property of Seller at any time in Prestige's
     possession.

12.  FINANCING STATEMENTS. Seller will, at its expense perform all acts and
     execute all documents requested by Prestige at any time to evidence,
     perfect, maintain and enforce Prestige's security interest and other rights
     in the Collateral and the priority thereof. Upon request, at any time and
     from time to time, Seller will execute and deliver to Prestige one or more
     UCC financing statements (in form and substance satisfactory to Prestige
     and its counsel).

13.  HOLD IN TRUST. Seller will hold in trust and safekeeping, as the property
     of Prestige and immediately turn over to Prestige, the identical check or
     other form of payment received by Seller if payment on the Accounts comes
     into Seller's possession. Should Seller come into possession of a check
     comprising payments owing to both Seller and Prestige, Seller shall turn
     over said check to Prestige. Thereafter, Prestige will refund Seller's
     portion, if any, to Seller.

14.  FINANCIAL RECORDS. Seller will furnish to Prestige financial statements and
     such other information as is, from time to time, requested by Prestige.

15.  BOOK ENTRY. Seller will immediately, upon the sale of the Accounts, make
     the proper entry on its books and records disclosing the absolute sale of
     the Accounts to Prestige.

16.  POWER OF ATTORNEY. In order to implement this Agreement, Seller irrevocably
     appoints Prestige its special attorney in fact or agent with power to:

         (a) Strike out Seller's address on any correspondence to any account
             debtor and put on Prestige's address;

         (b) Receive and open all mail addressed to Seller via Prestige's
             address;

         (c) Endorse the name of Seller or Seller's trade name on any checks or
             other evidences of payment that may come into the possession of
             Prestige in connection with the Accounts;

         (d) In Seller's name, or otherwise, demand, sue for, collect any and
             all monies due in connection with the Accounts; and

         (e) Compromise, prosecute or defend any action, claim or proceeding
             relative to the Accounts;

     The authority granted to Prestige shall remain in full force and effect
     until the Accounts are paid in full and the entire indebtedness of Seller
     to Prestige is discharged.

17.  NOTIFICATION; VERIFICATION OF ACCOUNTS

         (a) Without in any way limiting the terms and provisions of paragraph 5
             (m) hereinabove, Prestige may at any time and from time to time, in
             its sole discretion, notify any account debtor to make payment on
             any of Seller's open invoices to Prestige; and

         (b) Prestige may at any time verify the Accounts utilizing an audit
             control company, any agent of Prestige or any other means deemed
             appropriate by Prestige.

     impose any duty or obligation upon Prestige in favor of any account debtor
     and/or any other party in connection with the Accounts.

19.  FUTURE ASSIGNMENTS. Seller may from time to time, at Seller's option, sell,
     transfer and assign different Accounts to Prestige. The future sale of any
     Accounts shall be subject to and governed by this Agreement and such
     Accounts shall be identified by separate and subsequent Assignments.

20.  DISCRETION. Nothing contained in this Agreement shall be construed to
     impose any obligation upon Prestige to purchase Accounts from Seller.
     Prestige shall at its sole discretion determine which Accounts it shall
     purchase. Further, Prestige shall have the absolute right at any time to
     cease accepting any further assignments from Seller.

21.  LEGAL FEES: EXPENSES. Seller will pay on demand any and all collection
     expenses and reasonable attorneys' fees that Prestige incurs in the event
     it should become necessary for Prestige to enforce its rights under this
     Agreement. In addition, Seller will pay on demand all costs and expenses
     incurred by Prestige in connection with the preparation, execution and
     delivery of this Agreement and any supplement or modification thereof, and
     in any way relating to the transactions contemplated by this Agreement,
     including, without limitation, all reasonable attorneys' fees, Federal

     transfer any or all of its rights and obligations under this Agreement to
     any party without the prior written consent of Prestige.

23.  WAIVER: ENTIRE AGREEMENT. No failure or delay on Prestige's part in
     exercising any right, power or remedy granted to Prestige herein, will
     constitute or operate as a waiver thereof, nor shall any single or partial
     exercise of any such right, power or remedy preclude any other or further
     exercise thereof or the exercise of any other right set forth herein. This
     agreement contains the entire agreement and understanding of the parties
     hereto and no amendment, modification or waiver of, or consent with respect
     to, any provision of this Agreement, will in any event be effective unless
     the same is in writing and signed and delivered by Prestige.

24.  NEW JERSEY LAW. This agreement shall be deemed executed in the State of New
     Jersey and, in all respects, shall be governed and construed in accordance
     with the laws of the State of New Jersey.

25.  INDEMNITY. Seller shall hold Prestige harmless from and against any action
     or other proceeding brought by any account debtor against Prestige arising
     from Prestige's collecting or attempting to collect any of the Accounts.

26.  TERM. This Agreement will remain in effect until September 1, 2001 (the
     "Term"). Thereafter, the Term will be automatically extended for successive
     periods of three (3) months each unless either party provides the other
     with a written notice of cancellation at least sixty (60) days prior to the
