by deposit of United States Dollars in immediately available funds in a bank
account in the United States designated by Boeing.

                  2.8      Taxes.

                           2.8.1    Taxes.  Customer agrees to pay, and to
defend, indemnify and hold Boeing harmless from all Taxes imposed on Boeing or
on Customer by any government except to the extent that any such Tax is measured
by the net or gross income or excess profits, receipts, capital, franchise, net
worth or business privilege Taxes of Boeing. If Boeing has reason to believe
that any such tax is applicable, Boeing shall separately state the amount of
such tax on its invoice. Such Taxes shall exclude any and all penalties, fines,
similar fees or other assessments imposed by a country or governing body as a
result of any violation of competition or antitrust law.

                           2.8.2    Contests.  If a claim is made against any
party for Taxes with respect to which the other party is liable for a payment or
indemnity hereunder, the party making such claim will promptly give the other
notice in writing within 15 days of receipt of such claim; provided however,
that failure to give notice will not relieve any party of its obligations
thereunder. Either party may, in good faith, with due diligence and at its
expense, contest (or permit the other party to contest in the name of such
party) the validity, applicability, or amount of such Taxes. If either party
receives any refund on account of any suit or action for a Tax for which the
other party has provided funds hereunder, such party shall promptly, but in any
event within thirty (30) days of receipt of such refund, remit such refund to
the other party, together with any interest refunded on such amount.

                           2.8.3    Reimbursement of Boeing.  Customer will
promptly reimburse Boeing on demand, net of additional Taxes thereon, for any
Taxes that are imposed on and paid by Boeing or for which Boeing is responsible
for collecting.

Article 6.        Regulatory Requirements and Certificates.

                  6.1 Certificates. Boeing will manufacture each Aircraft to
conform to the appropriate Type Certificate issued by the United States Federal
Aviation Administration (FAA) for the specific model of Aircraft and will obtain
from the FAA and furnish to Customer at Delivery of each Aircraft a Standard
Airworthiness Certificate issued pursuant to Part 21 of the Federal Aviation
Regulations. Boeing will assist Customer prior to Delivery in obtaining other
certificates required by Customer to operate the Aircraft; however, Boeing shall
not be obligated to obtain any other certificates or approvals for the Aircraft.

                  6.2  FAA or Applicable Regulatory Authority Manufacturer
                  Changes.

                  6.3 FAA Operator Changes. Boeing will deliver each Aircraft
with Operator Changes incorporated or, at Boeing's option, with suitable
provisions for the incorporation of such Operator Changes. Customer will pay
Boeing for each Operator Change incorporated in each Aircraft as set forth in
(a) and (b) below:



                         *This confidential information
                           has been omitted and filed
                         separately with the Commission.


                  6.4 Delay and Change Order. If Delivery of any Aircraft is
delayed by the incorporation in such Aircraft of any Change required to be made
under Articles 6.2 or 6.3 such delay shall be an Excusable Delay within the
meaning of Article 10. Boeing shall issue and Customer shall accept a Change
Order reflecting any Change required to be made under Article 6.2 or 6.3, which
Change Order shall set forth in detail the particular Changes to be made therein
and the effect, if any, of such changes on design, performance, weight, balance,
time of Delivery and the Aircraft Basic Price of the affected Aircraft.
Notwithstanding the provisions of Article 7 of this AGTA, any Change Orders
issued pursuant to this Article 6.4 need not be signed by Customer and shall be
deemed to be accepted by Customer and effective upon the date of Boeing's
transmittal of such Change Order.

                  6.5 Discontinuance. If the use of either of the Certificates
identified in Article 6.1 is discontinued during the performance of this
Agreement, thereafter reference to such discontinued Certificate shall be deemed
a reference to any other certificate or instrument issued by the FAA which
corresponds to such Certificate or, if there should not be any such other
certificate or instrument, then Boeing shall be deemed to have obtained such
discontinued Certificate or Certificates upon demonstrating that each Aircraft
complies substantially with the performance guarantees set forth in the Detail
Specification.

Article 7.        Detail Specification; Changes.

                  7.1 Change Order. The Detail Specification for an applicable
Aircraft model may, by mutual agreement, be amended from time to time by Change
Order or other written agreement, which shall set forth in detail the particular
changes to be made therein, and the effect, if any, of such changes on design,
performance, weight, balance, time of Delivery and basic price of the Aircraft.
Such Change Orders and other written agreements shall be signed on behalf of
Customer and Boeing by their respective duly authorized representatives.

                  7.2 Detail Specification Changes.  All changes which revise
the Detail Specification shall be made in accordance with the procedures
hereinafter set forth.

                           7.2.1    Master Change/Other Changes.  The Detail
Specification may be revised by mutual agreement of the parties by Master Change
(MC), Production Record Revisions (PRR), Rapid Revisions (RR), or other change
processes (which are acceptable to the FAA) which may be requested by Customer
or initiated by Boeing, as appropriate. Each change shall be proposed to
Customer by Boeing and shall describe the change to be accomplished, establish
the Aircraft effectivity, and the effect, if any, on weight, and the Aircraft
Basic Price . When signed by duly authorized representatives of both parties,
such changes shall be binding on both parties and may be released immediately by
Boeing to production. After acceptance of the change by Customer, Boeing will
provide Specification Revision Inserts (SRI) as addendum sheets to maintain the
currency of the Detail Specification. Periodically, such agreed changes shall be
accumulated in formal Change Orders. A complete revision to the Detail
Specification will be issued concurrently with the Change Order. The revision
will incorporate the SRIs. As the Detail Specification revisions are predicated
on incorporating accepted changes, formal release of the revised Detail
Specification shall be independent of formal acceptance of the Change Order.

7.2.2 Development Change. Development Changes are those deemed necessary to
correct defects, improve the Aircraft, prevent delay, or insure compliance with
this Agreement but which have no materially adverse effect on the design,
replaceability, interchangeability, weight, balance or functional
characteristics of the Aircraft. The Detail Specification may be revised by
Boeing without Customer's consent to incorporate Development Changes (DC's)
where such changes do not adversely affect price, Delivery, guaranteed weight or
guaranteed performance of the Aircraft or interchangeability, or replaceability
or functional characteristics of Spare Parts; *This confidential information has

Article 8.        Representatives, Inspection, Demonstration Flights, Test
                  Data, and Performance Guarantee Compliance.

                  8.1 Office Space. Commencing with the date of this AGTA and
continuing until the last Delivery of an Aircraft, Boeing shall furnish, without
additional charge, suitable office space and equipment in or conveniently
located with respect to its plant for the accommodation of up to five (5)
personnel of Customer.

                  8.2 Inspection. Boeing's manufacture of the Aircraft, and all
components obtained by Boeing therefor, shall at all reasonable times be open to
inspection by any duly authorized representatives of Customer. However, if
access to any part of Boeing's plant where manufacture is in progress or
components are stored is restricted by the United States Government, Boeing
shall be allowed a reasonable time to make the items available for inspection
elsewhere than in the restricted area. All inspections by Customer's
representatives shall be performed in such manner as not to unduly delay or
hinder manufacture or performance by Boeing.

                  8.3 Demonstration Flights. Each Aircraft shall be test flown
by Boeing for such periods as may be required to demonstrate to Customer the
functioning of the Aircraft and its equipment. Customer shall be permitted to
have a reasonable number of representatives participate in such flights as
observers.

                  8.4 Test Data; Performance Guarantee Compliance. Boeing shall
furnish to Customer, as soon as practicable, flight test data, obtained on an
aircraft of the type purchased hereunder, certified as correct by Boeing, to
evidence compliance with any performance guarantees set forth in the applicable
Purchase Agreement. Any performance guarantee shall be deemed to be met if
reasonable engineering interpretations and calculations based on such flight
test data establish that the Aircraft would, if actually flown, comply with such
guarantee.

                  8.5 Special Aircraft Test Requirements.  Subject to Customer's
prior consent, Boeing may use the Aircraft for flight and ground tests prior to
Delivery if such tests are deemed necessary by Boeing.

                  (a)      to obtain the certificates required under Article
                  6.1, and

                           (i)      other aircraft of the type purchased
                           hereunder are not available for such tests, or


                                       22


AGTA-DAL


   25





                      (ii) special features incorporated in the Aircraft (but
                      not incorporated in other aircraft of the type purchased
                      hereunder) necessitate such tests, or

                      (iii) the Engines (as defined in Exhibit D to this AGTA)
                      to be installed on the Aircraft are of different
                      manufacture or type from those installed on other aircraft
                      of the type purchased hereunder; or

                  (b) to evaluate actual or contemplated changes for the
improvement of aircraft of the type purchased hereunder which may be requested
for incorporation by Customer, in production or by retrofit, in any Aircraft.

Customer shall accept Delivery of any Aircraft used for such flight and ground
tests without any reduction in price for depreciation or wear and tear resulting
therefrom.

Article 9.        Delivery.

                  9.1 Notices of Delivery Dates. Boeing will notify Customer of
the approximate delivery date of each Aircraft at least sixty (60) days before
the approximate delivery date and again at least twenty-one (21) days before the
scheduled delivery date.

                  9.2 Place of Delivery. Each Aircraft shall be delivered at an
airport in the State of Washington selected by Boeing or at such alternate site
as may be mutually agreed upon in writing. If Delivery is made at an alternate
site, at Customer's request, Customer shall promptly reimburse Boeing for any
increased costs incurred by Boeing as a result thereof.

                  9.3 Documents of Title. Upon Delivery of and payment for each
Aircraft, Boeing shall deliver to Customer a bill of sale duly conveying to
Customer good title to such Aircraft free and clear of all liens, claims,
charges and encumbrances of every kind whatsoever, and such other appropriate
documents of title as Customer may reasonably request.

                  9.4 Delay. *This confidential information has been omitted

Article 10.       Excusable Delay.

                  10.1 Boeing Excusable Delay. Boeing will not be liable for any
delay beyond the Scheduled Delivery Month of an Aircraft or other performance
under a Purchase Agreement caused by (i) acts of God; (ii) war or armed
hostilities; (iii) government acts or priorities; (iv) fires, floods or
earthquakes; (v) strikes or labor troubles causing cessation, slowdown or
interruption of work; or (vi) any other cause to the extent such cause is beyond
Boeing's control and not occasioned by Boeing's fault or negligence. A delay
resulting from any such cause is defined as a Boeing Excusable Delay.

                  10.6 Aircraft Damaged Beyond Repair. If an Aircraft is
destroyed or damaged beyond repair for any reason before Delivery, Boeing will
give written notice to Customer specifying the earliest month possible,
consistent with Boeing's other contractual commitments and production
capabilities in which Boeing can deliver a replacement. Customer will have
thirty (30) days from receipt of such notice to elect to have Boeing manufacture
a replacement aircraft under the same terms and conditions of purchase, except
that the calculation of the Escalation Adjustment will be based upon the
Scheduled Delivery Month in effect immediately prior to the date of such notice,
or, failing such election, the applicable Purchase Agreement will terminate with
respect to such Aircraft. Boeing will not be obligated to manufacture a
replacement aircraft if reactivation of the production line for the specific
model of aircraft would be required.

                  10.7 Consequences of Termination. Termination of a Purchase
Agreement with respect to an Aircraft under this Article will discharge all
obligations and liabilities of Customer with respect to such Aircraft. If
Customer terminates a Purchase Agreement with respect to an Aircraft under this
Article, Boeing may elect,

                           11.1.2   Definition of Customer. For the purposes of
this Article, Customer is defined as Delta Air Lines, Inc., its divisions,
subsidiaries, affiliates, the assignees of each, and their respective directors,
officers, employees, and agents.

                  11.2     Insurance.

                           11.2.1   Insurance Requirements.  Customer will
purchase and maintain insurance acceptable to Boeing and will provide a
certificate of such insurance that names Boeing as an additional insured for any
and all claims and liabilities for injury to or death of any person or persons,
including employees of Customer but not employees of Boeing, or for loss of or
damage to any property, including any aircraft, arising out of or in any way
relating to Materials, training, services, or other things provided under
Exhibit B of this AGTA, which will be incorporated by reference into the
applicable Purchase Agreement, whether or not arising in tort or occasioned by
the negligence of Boeing, except with respect to legal liability to persons or
parties other than Customer or Customer's assignees arising out of an accident
caused solely by a product defect in an Aircraft. Customer will provide such
certificate of insurance at least thirty (30) days prior to the scheduled
delivery of the first Aircraft under a Purchase Agreement. The insurance
certificate will reference each Aircraft delivered to Customer pursuant to each
applicable Purchase Agreement. Annual renewal certificates will be submitted to
Boeing before the expiration of the policy periods. The form of the insurance
certificate, attached as Appendix 1, states the terms, limits, provisions, and
coverages required by this Article 11.2.1. The failure of Boeing to demand
compliance with this 11.2.1 in any year will not in any way relieve Customer of
its obligations hereunder nor constitute a waiver by Boeing of these
obligations.

                           11.2.2   Noncompliance with Insurance Requirements.
If Customer fails to comply with any of the insurance requirements of Article
11.2.1 or if any of the insurers fails to pay a claim covered by the insurance
or otherwise fails to meet any of insurer's obligations required by Appendix 1,
Customer will provide the same protection to Boeing as that required by Article
11.2.1 above.

                           11.2.3   Definition of Boeing.  For purposes of this
article, Boeing is defined as The Boeing Company, its divisions, subsidiaries,
affiliates, assignees of each, and their respective directors, officers,

2.       Warranty.

         2.1      Coverage.  Boeing warrants that at the time of Aircraft
delivery:

                  (i)      the Aircraft will conform to the then current
                           revision of the Detail Specification applicable to
                           the Aircraft delivered, except for portions stated to
                           be estimates, approximations or design objectives;

                  (ii)     all Boeing Products in the Aircraft will be free from
                           defects in material and workmanship, including
                           process of manufacture;

                  (iii)    all Boeing Products in the Aircraft will be free from
                           defects in design, including selection of materials
                           and the process of manufacture, in view of the state

Labor to perform certain inspections of the Aircraft to determine the existence
of a covered defect in a Boeing Product, provided:

                  4.2.1 the inspections for the covered defect are mandated by
the FAA or other governmental authority having jurisdiction over the Customer's
operation or are recommended by a Boeing service bulletin or service letter
issued by Boeing during the warranty period; and

                  4.2.2 *This confidential information has been omitted and
filed separately with the Commission.





         4.3 Credit Memorandum Reimbursement.  Boeing will make all
reimbursements by credit memoranda which may be applied toward the purchase of
Boeing goods and services.

         4.4 Maximum Reimbursement. Unless previously agreed, the maximum
reimbursement for Direct Labor and Direct Materials used to Correct a defective
Boeing Product will not exceed 65% of Boeing's then-current sales price for a
new replacement Boeing Product. If the estimate to Correct a defective Boeing
Product exceeds 65% of the price of a new part, Boeing will either provide a
credit to Customer at 65% of the replacement price of a new part or a new
replacement part, at Customer's' option.

         4.5      Year 2000 Compliance.

                  4.5.1 Customer has requested certain commitments from Boeing
regarding the year 2000 Compliance. Year 2000 Compliance Software is software
which will accommodate the change from year 1999 to and beyond year 2000. In
response to this request, Boeing warrants to Customer the following:

                  4.5.2 Boeing has designed its software system to preclude any
interruption in its operation due to the anomalies resulting from the value for
current date.

                  4.5.3 Boeing has designed its software system to produce
desired results for all valid date values within the application domain and in
combination with other products, prior to, through and beyond the year 2000.

                  4.5.4 Boeing's software systems use of date elements in
interfaces will permit specifying the century to eliminate date ambiguity
without human intervention, including leap year calculations.

                  4.5.5 Boeing's software systems will, where any date element
is represented without a century, provide that the correct century shall be
unambiguous for all manipulations involving that element.

                  In the event such software does not meet the requirements in
4.5.2 through 4.5.5 above at the time of Aircraft delivery to Customer, or in
the case of software furnished to Customer, pursuant to Exhibit B, Part 3 of the
AGTA such


                                     C-2-3

AGTA-DAL


   61




software, Boeing will, at its election, either modify such software to be Year
2000 Compliant, replace such non-compliant software with software that is Year
2000 Compliant or provide a reasonable workaround to allow continued use of such
software until final correction to the software can be accomplished. Customer's
remedies under this paragraph are sole and exclusive and are limited to
no-charge modification, replacement or workaround of the non-compliant software
and will be accomplished either prior to Aircraft delivery or, following
Aircraft delivery, as soon as practicable after discovery of noncompliance.

5.       Discovery and Notice.

         5.1 For a claim to be considered for reimbursement:

             (i)      the defect must be discovered during the warranty
                      period. For the purposes of this Section 5.1. (i)
                      the warranty period is extended for the periods
                      described in paragraph 3 and Supplemental Exhibits
                      to the Purchase Agreements.

             (ii)     Boeing Product Assurance Contracts must receive written
                      notice of the discovery no later than 90 days after
                      expiration of the warranty period.

         5.2 Receipt of Customer's notice of the discovery of a defect secures
Customer's rights to remedies under this Exhibit C, whether or not Customer has
performed the Correction at the time of the notice.

         5.3 Boeing may release service bulletins or service letters advising
Customer of the availability of certain warranty remedies. When such advice is
provided, Customer will be deemed to have fulfilled the requirements for
discovery of the defect and submittal of notice under this Exhibit C as of the
date specified in the service bulletin or service letter.

filed separately with the Commission.









7.       Limited Warranty for Certain Materials.

         7.1 Boeing warrants that, at the time of delivery, all Materials

                 equipment or qualified personnel to perform the
                           Correction; and

                  (iii)    it is not practical, in Boeing's estimation, to
                           dispatch Boeing personnel to perform the Correction
                           at a remote site.

the cooperative efforts of Boeing and the Supplier and will promptly advise
Customer of the resulting corrective actions and recommendations.

5.       General.

         So long as the Interface problem is corrected to Customer's
satisfaction or Customer is otherwise satisfied with the remedial action
proposed by Boeing to correct the Interface Problem, Customer will, if requested
by Boeing, assign to Boeing any of its rights against any supplier as Boeing may
require to fulfill its obligations hereunder.

                            ESCALATION ADJUSTMENT


1.           Formula.

             Airframe and Optional Features price adjustments (Airframe Price
Adjustment); are used to allow prices to be stated in current year dollars at
the signing of the applicable purchase agreement and to adjust the amount to be
paid by Customer at delivery for the effects of economic fluctuation. The
Airframe Price Adjustment will be determined at the time of aircraft delivery in
accordance with the following formula:

             P(a) = (P)(L + M - 1)

             Where:

                      P(a)   = Airframe Price Adjustment. (For Model 737-600,
                             737-700 and 737-800, the Airframe Price includes
                             the Engine Price.)

                      L =    .65 x  ECI
                                    ---
                                    base year index (as set forth in Table 1 of
                                     the applicable purchase agreement)

                      M =    .35 x  ICI
                                    ---
                                    base year index (as set forth in Table 1 of
                                     the applicable purchase agreement)

                      P      = Airframe Price plus Optional Features Price (as
                             set forth in the applicable purchase agreement).

                      ECI is a value determined using the U.S. Department of
                      Labor, Bureau of Labor Statistics "Employment Cost Index
                      for workers in aerospace manufacturing" (ECI code 3721),
                      calculated by establishing a three-month arithmetic
                      average value (expressed as a decimal and rounded to the
                      nearest tenth) using the values for the fifth, sixth and
                      seventh months prior to the month of scheduled delivery of
                      the applicable aircraft. As the Employment Cost Index
                      values are only released on a quarterly basis, the value
                      released for the month of March will be used for the
                      months of January and February; the value for June used
                      for April and May; the value for September used for July
                      and August; and the value for December used for October
                      and November.

                      ICI is a value determined using the U.S. Department of
                      Labor, Bureau of Labor Statistics "Producer Prices and
                      Price Index - Industrial Commodities Index", calculated as
                      a 3-month arithmetic average of the released monthly
                      values (expressed as a decimal and rounded to the


                                      D-1

AGTA-DAL

   79



                      nearest tenth) using the values for the 5th, 6th and 7th
                      months prior to the month of scheduled delivery of the
                      applicable aircraft.

                      As an example, for an aircraft scheduled to be delivered
                      in the month of January, the months June, July and August
                      of the preceding year will be utilized in determining the
                      value of ECI and ICI.

Note:        i.       In determining the values of L and M, all  calculations
             and resulting values will be expressed as a decimal rounded to the
             nearest ten-thousandth.

             ii.      .65 is the numeric ratio attributed to labor in the
             Airframe Price Adjustment formula.

             iii.     .35 is the numeric ratio attributed to materials in the
             Airframe Price Adjustment formula.

             iv. The denominators (base year indices) are the actual average
             values reported by the U.S. Department of Labor, Bureau of Labor
             Statistics (base year June 1989 = 100). The applicable base year
             and corresponding denominator will be provided by Boeing in the
             applicable purchase agreement.

2.           Values to be Utilized in the Event of Unavailability.

             2.1 If the Bureau of Labor Statistics substantially revises the
methodology used for the determination of the values to be used to determine the
ECI and ICI values (in contrast to benchmark adjustments or other corrections of
previously released values), or for any reason has not released values needed to
determine the applicable Airframe Price Adjustment, the parties will, prior to
the delivery of any such aircraft, select a substitute from other Bureau of
Labor Statistics data or similar data reported by non-governmental
organizations. Such substitute will result in the same adjustment, insofar as
possible, as would have been calculated utilizing the original values adjusted
for fluctuation during the applicable time period. However, if within 24 months
after delivery of the aircraft, the Bureau of Labor Statistics should resume
releasing values for the months needed to determine the Airframe Price
Adjustment, such values will be used to determine any increase or decrease in
the Airframe Price Adjustment for the aircraft from that determined at the time
of delivery of the aircraft.

             2.2 Notwithstanding Article 2.1 above, if prior to the scheduled
delivery month of an aircraft the Bureau of Labor Statistics changes the base
year for determination of the ECI and ICI values as defined above, such re-based
values will be incorporated in the Airframe Price Adjustment calculation.

             2.3 In the event escalation provisions are made non-enforceable or
otherwise rendered void by any agency of the United States Government, the
parties agree, to the extent they may lawfully do so, to equitably adjust the
Purchase Price of any affected aircraft to reflect an allowance for increases or
decreases in labor compensation

and material costs occurring since February, 1995, which is consistent with the
applicable provisions of paragraph 1 of this Exhibit D.

Note:        i.  The values released by the Bureau of Labor Statistics and
             available to Boeing 30 days prior to the scheduled delivery month
             of an aircraft will be used to determine the ECI and ICI values for
             the applicable months (including those noted as preliminary by the
             Bureau of Labor Statistics) to calculate the Airframe Price
             Adjustment for the aircraft invoice at the time of delivery. The
             values will be considered final and no Aircraft Price Adjustments
             will be made after Aircraft delivery for any subsequent changes in
             published Index values.

         4. For all purposes of this Assignment, Boeing will not be deemed to
have knowledge of or need to recognize the occurrence, continuance or
discontinuance of any event of default or termination under [specify document]
unless and until Boeing receives from Assignee written notice thereof, addressed
to its Vice President - Contracts, Boeing Commercial Airplane Group at P.O. Box
3707, Seattle, Washington 98124, if by mail, or to 32-9430 Answerback BOEINGREN
RNTN, if by telex. Until such notice has been given, Boeing will be entitled to
deal solely and exclusively with Assignor. Thereafter, until Assignee has
provided Boeing written notice that any such events no longer continue, Boeing
will be entitled to deal solely and exclusively with Assignee. Boeing may
conclusively rely on any such notice.

         5. Notwithstanding anything herein contained to the contrary, it is
expressly agreed that: (a) prior to the Delivery Date Assignor will perform its
obligations with respect to the Aircraft to be performed by it on or before such
delivery, (b) Assignor will at all times remain liable to Boeing under the
Boeing Purchase Agreement to perform all obligations of Customer thereunder to
the same extent as if this Assignment had not been executed, and (c) the
exercise by Assignee of any of the assigned rights will not release Assignor
from any of its obligations to Boeing under the Boeing Purchase Agreement,
except to the extent that such exercise constitutes performance of such
obligations.

         6. Notwithstanding anything herein to the contrary (but without in any
way releasing Assignor from any of its obligations under the Boeing Purchase
Agreement), Assignee confirms for the benefit of Boeing that, insofar as the
provisions of the Boeing Purchase Agreement relate to the Aircraft, in
exercising any rights under the Boeing Purchase Agreement, or in making any
claim with respect to the Aircraft or other things (including, without
limitation, Material, training and services) delivered or to be delivered
pursuant to the Boeing Purchase Agreement, the terms and conditions of the
Boeing Purchase Agreement, including, without limitation, the DISCLAIMER AND
RELEASE and EXCLUSION OF CONSEQUENTIAL AND OTHER DAMAGES in Article 12 of Part 2
of Exhibit C to the Aircraft General Terms Agreement which were incorporated by
reference into the Boeing Purchase Agreement and the insurance provisions in
Article 8.2 of the Aircraft General Terms Agreement which were incorporated by
reference into the Boeing Purchase Agreement, will apply to and be binding on
Assignee to the same extent as if Assignee had been the original "Customer"
thereunder. Assignee further agrees, expressly for the benefit of Boeing, upon
written request of Boeing, promptly to execute and deliver such further
assurances and documents and take such further action as Boeing may reasonably
request in order to obtain the full benefits of Assignee's agreements in this
paragraph.

         7. Nothing contained herein will subject Boeing to any liability to
which it would not otherwise be subject under the Boeing Purchase Agreement,
modify in any respect the contract rights of Boeing thereunder or require Boeing
to divest itself of title to or possession of the Aircraft or other things until
delivery thereof and payment therefor as provided therein.

         8. Notwithstanding anything herein to the contrary, after receipt of
notice of any event of default or termination under [specify document], Boeing
will continue to owe Assignor moneys in payment of claims made or obligations
arising before such notice, which moneys may be subject to rights of set-off
available to Boeing under applicable law. Similarly, after receipt of notice
that such event of default or termination no longer continues, Boeing will
continue to owe Assignee moneys in payment of claims made or obligations arising
before such notice, which moneys may be subject to rights of set-off available
to Boeing under applicable law.

         9. Effective at any time after an event of default has occurred, and
for so long as such event of default is continuing, Assignor does hereby
constitute Assignee as Assignor's true and lawful attorney, irrevocably, with
full power (in the name of Assignor or otherwise) to ask, require, demand,
receive and give acquittance for any and all moneys and claims for moneys due
and to become due under or arising out of the Boeing Purchase Agreement in
respect of the Aircraft, to the extent assigned by this Assignment.

         10. Assignee agrees expressly for the benefit of Boeing and Assignor
that it will not disclose, directly or indirectly, any terms of the Boeing
Purchase Agreement; provided, that Assignee may disclose any such information
(a) to its special counsel and public accountants, (b) as required by applicable
law to be disclosed or to the extent that Assignee may have received a subpoena
or other written demand under color of legal right for such information, but it
will first, as soon as practicable upon receipt of such requirement or demand,
furnish an explanation of the basis thereof to Boeing, and will afford Boeing
reasonable opportunity to obtain a protective order or other reasonably
satisfactory assurance of confidential treatment for the information required to
be disclosed, and (c) to any bona fide potential purchaser or lessee of the
Aircraft. Any disclosure pursuant to (a) and (c) above will be subject to
execution of a confidentiality agreement substantially similar to this paragraph
10.

         11. This Assignment may be executed by the parties in separate
counterparts, each of which when so executed and delivered will be an original,
but all such counterparts will together constitute but one and the same
instrument.
