ITEM 22. UNDERTAKINGS.
 
     (1) The undersigned registrants hereby undertake as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     (2) The registrants undertake that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of the
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the Registration Statement through the date
of responding to the request.
 
     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
     The undersigned registrants hereby undertake to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and
regulations prescribed by the SEC under Section 305(b)(2) of the Act.

                                   relating to

                         BOEING MODEL 747-400F AIRCRAFT


    1.   ENGINE ESCALATION.

(a) The Aircraft Basic Price of each Aircraft set forth in Table 1 of the
Purchase Agreement includes an aggregate price for CF6-80C2 engines and all
accessories, equipment and parts provided by the engine manufacturer. The
adjustment in Engine price applicable to each Aircraft (Engine Price Adjustment)
will be determined at the time of Aircraft delivery in accordance with the
following formula:

         P(e) =         (P(b) x  CPI  ) - P(b)
                        Base Year Index (CPI), as set forth in Table 1
                        of the Purchase Agreement

(b) The following definitions will apply herein:

         P(e)  =        Engine Price Adjustment
         P(b)  =        Engine Base Price (per Aircraft), as set forth in Table
                        1 of the Purchase Agreement.

         CPI is the Composite Price Index, a value determined using the Bureau
         of Labor Statistics, U.S. Department of Labor actual data in
         accordance with the formula below. The Index values utilized in the
         formula will be the numbers shown in the actual data for the ninth
         month prior to the month of scheduled Aircraft delivery or the ninth
         month prior to the Base Year Dollars month set forth in Table 1.

                 CPI = L + C + M + E

                 L =    The Labor Index will be equal to the quotient of the 
                        value associated with the Aircraft Delivery Month 
                        divided by the value associated with the Base Year 
                        Dollar month in "Hourly Earnings of Aircraft Engines and
                        Engine Parts Production Workers" SIC 3724, multiplied 
                        by 100 and then by 30%.


                                     EE1-1
P.A. No. 2021
<PAGE>   23


                 C =    The Industrial Commodities Index will be equal to 30%
                        of the Producer Price Index for "all commodities other
                        than Farm and Foods," Code 3-15 associated with the
                        scheduled Aircraft delivery month.

                 M =    The Metals and Metal Products Index will be equal to
                        30% of the Producer Price Index for "Metals and Metal
                        Products," Code 10 associated with the scheduled
                        Aircraft delivery month.

                 E =    The Fuel Index will be equal to 10% of the Producer
                        Price Index for "Fuel and Related Products and Power,"
                        Code 5 associated with the scheduled Aircraft delivery
                        month.

The Engine Price Adjustment will not be made if it would result in a decrease in
the Engine Base Price.

(c) The values of the Average Hourly Earnings and Producer Price Indices used
will be those published as of a date 30 days prior to the scheduled Aircraft
delivery to Customer. Such values will be considered final and no Engine Price
Adjustment will be made after Aircraft delivery for any subsequent changes in
published Index values.

(d) In the event the Engine price escalation provisions are made non-enforceable
or otherwise rendered null and void by any agency of the United States
Government, or if the U.S. Department of Labor, Bureau of Labor Statistics (i)
substantially revises the methodology (in contrast to benchmark adjustments or
other corrections of previously published data) or (ii) discontinues publication
of any of the data referred to above, General Electric Company (GE) agrees to
meet jointly with Boeing and Customer, (to the extent such parties may lawfully
do so,) to jointly select a substitute for the revised or discontinued data;
such substitute data to lead in application to the same adjustment result,
insofar as possible, as would have been achieved by continuing the use of the
original data as it may have fluctuated had it not been revised or discontinued.
If such Engine price escalation provisions, methodology or data publication are
subsequently reinstated, Boeing will make adjustments consistent with the
agreements defined in this Supplemental Exhibit EE1.

NOTE:        The factor (CPI divided by the base year index) by which the Engine
             Base Price is to be multiplied will be expressed as a decimal and
             rounded to the nearest thousandth. Any rounding of a number, as
             required under this Supplemental Exhibit EE1 with respect to
             escalation of the Engine price, will be accomplished as follows: if
             the first digit of the portion to be dropped from the number to be
             rounded is five or greater, the preceding digit will be raised to
             the next higher number.

         2.       ENGINE WARRANTY AND PRODUCT SUPPORT PLAN.

Boeing has obtained from GE the right to extend to Customer the provisions of
GE's Warranty and Product Support Plan; subject, however, to Customer's
acceptance of the conditions set forth herein and in such Warranty and Product
Support Plan. Accordingly, Boeing hereby extends to Customer and Customer hereby
accepts the provisions of GE's Warranty and Product Support Plan hereinafter set
forth, and such Warranty and Product Support Plan shall apply to all CF6
turbofan engines including all Modules and Parts thereof (Engines) installed in
the Aircraft at the time of delivery or purchased from Boeing by Customer for
support of the Aircraft except that, if Customer and GE have executed a General
Terms Agreement, then the terms of that Agreement shall be substituted for and
supersede the below-stated provisions and such provisions shall be of no force
or effect and neither Boeing nor GE shall have any obligation arising therefrom.
In consideration for Boeing's extension of the GE Warranty and Product Support
Plan to Customer, Customer hereby releases and discharges Boeing from any and
all claims, obligations and liabilities whatsoever arising out of the purchase
or use of such CF6 turbofan engines and Customer hereby waives, releases and
renounces all its rights in all such claims, obligations and liabilities.

         2.1.     Title. GE warrants that at the date of delivery, GE has legal
         title to and good and lawful right to sell its CF6 engine products and
         furthermore warrants that such title is free and clear of all claims,
         liens and encumbrances of any nature whatsoever.

         2.2.     Patents.

                  2.2.1. GE will handle all claims and defend any suit or
                  proceeding brought against Customer insofar as based on a
                  claim that any product or part furnished under this Agreement
                  constitutes an infringement of any patent of the United
                  States, and will pay all damages and costs awarded therein
                  against Customer. This paragraph will not apply to any product
                  or any part manufactured to Customer's design or to the
                  aircraft manufacturer's design. As to such product or part, GE
                  assumes no liability for patent infringement.

                  2.2.2. GE's liability hereunder is conditioned upon Customer
                  promptly notifying GE in writing and giving GE authority,
                  information and assistance (at GE's expense) for the defense
                  of any suit. In case said equipment or part is held in such
                  suit to constitute infringement and the use of said equipment
                  or part is enjoined, GE shall expeditiously, at its own
                  expense and at its option, either (1) procure for Customer the
                  rights to continue using said product or part; (2) replace the
                  same with satisfactory and noninfringing product or part; or
                  (3) modify the same so it becomes satisfactory and
                  noninfringing.


                                     EE1-3
P.A. No. 2021
<PAGE>   25

                  The foregoing shall constitute the sole remedy of Customer
                  and the sole liability of GE for patent infringement.

                  2.2.3. The above provisions also apply to products which are
                  the same as those covered by this Agreement and are delivered
                  to Customer as part of the installed equipment on CF6 powered
                  Aircraft.

         2.3. Initial Warranty. GE warrants that CF6 engine products will
         conform to GE's applicable specifications and will be free from defects
         in material and workmanship prior to Customer's initial use of such
         products. The provisions of the GE CF6 Product Support Plan shall
         apply.

         2.4. Product Support Plan. GE warrants and extends to Customer the
         provisions of GE's CF6 Product Support Plan in effect on the date of
         the execution of this Purchase Agreement.

         2.5. Warranty Pass On. GE will, upon the written request of Customer,
         extend Warranty coverage to Engines, Modules and Parts sold by Customer
         to another operator to the extent only, however, that such coverage
         exists at the time of such sale and subject to the provisions of the
         Warranty.

         2.6. Limitations. THE PROVISIONS SET FORTH HEREIN ARE EXCLUSIVE AND ARE
         IN LIEU OF ALL OTHER WARRANTIES WHETHER WRITTEN, ORAL OR IMPLIED. THERE
         ARE NO IMPLIED WARRANTIES OF FITNESS OR MERCHANTABILITY. SAID
         PROVISIONS SET FORTH THE MAXIMUM LIABILITY OF GE WITH RESPECT TO CLAIMS
         OF ANY KIND, INCLUDING NEGLIGENCE, ARISING OUT OF MANUFACTURE, SALE,
         POSSESSION, USE OR HANDLING OF THE PRODUCTS OR PARTS THEREOF OR
         THEREFOR, AND IN NO EVENT SHALL GE'S LIABILITY TO CUSTOMER EXCEED THE
         PURCHASE PRICE OF THE PRODUCT GIVING RISE TO CUSTOMER'S CLAIM OR
         INCLUDE INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Subject: Seller Purchased Equipment

Reference: Purchase Agreement No. 2021 (the Purchase Agreement) between The
           Boeing Company (Boeing) and Atlas Air, Inc. (Customer) relating to
           Model 747-400F aircraft (the Aircraft)


This Letter Agreement amends and supplements the Purchase Agreement. All terms
used but not defined in this Letter Agreement have the same meaning as in the
Purchase Agreement.

Definition of Terms:

Seller Purchased Equipment (SPE): Buyer Furnished Equipment (BFE) that Boeing
purchases for Customer.

Developmental Buyer Furnished Equipment (DBFE): BFE not previously certified for
installation on the same model aircraft.

Developmental Seller Purchased Equipment (DSPE): DBFE which is converted to SPE.
This Letter Agreement does not include developmental avionics. Developmental
avionics are avionics that have not been previously certified for installation
on the same model aircraft.

1.   Price.

     Advance Payments. An estimated SPE price will be included in the Advance
Payment Base Price for the purpose of establishing the advance payments for the
Aircraft. The estimated price of this SPE for the Aircraft is United States [ ]
expressed in 1995 dollars.

     Aircraft Price. The Aircraft Price will be adjusted to reflect (i) the
actual costs charged Boeing by the SPE suppliers, (ii) a handling fee of [ ] of
such costs and (iii)

P.A. No. 2021
Seller Purchased Equipment
<PAGE>   33
2021-1
Page 2

transportation charges. If all DBFE, except for developmental avionics, is
converted to SPE, Boeing will waive the handling fee for all SPE.

2.   Responsibilities.

     2.1. Customer is responsible for:

          (i)  selecting the supplier on or before:

          N/A (SFE)         for galleys
          June 6, 1997      for seats;

          (ii)  selecting a FAA certifiable part; and

          (iii) providing to Boeing the SPE part specification/Customer
                requirements.

     2.2. Boeing is responsible for:

          (i)   placing and managing the purchase order with the supplier;

          (ii)  coordinating with the suppliers on technical issues;

          (iii) ensuring that the delivered SPE complies with the part
                specification;

          (iv)  obtaining certification of the Aircraft with the SPE installed;
                and

          (v)   obtaining for Customer the supplier's standard warranty for the
                SPE. SPE is deemed to be BFE for purposes of Part 2 of Exhibit
                C, the Product Assurance Document.

3.   Supplier Selection For SPE Galleys and Seats.

     In addition to those responsibilities described above, for SPE galleys and
seats the following provisions apply with respect to Customer's selection of
suppliers:

     Galley Requirements. Customer will provide Boeing the definitive galley
configuration requirements not later than June 6, 1997.



P.A. No. 2021
Seller Purchased Equipment
<PAGE>   34
2021-1
Page 3


     Bidder's List. For information purposes, Boeing will submit to Customer a
bidder's list of existing suppliers of seats and galleys within 120 days of the
supplier selection date shown above.

     Request for Quotation (RFQ). Approximately 90 days prior to the supplier
selection date, Boeing will issue its RFQ inviting potential bidders to submit
bids for the galleys and seats within 30 days of the selection date.

     Recommended Bidders. Not later than 15 days prior to the supplier selection
date, Boeing will submit to Customer a list of recommended bidders from which to
choose a supplier for the galleys and seats. The recommendation is based on an
evaluation of the bids submitted using price, weight, warranty and schedule as
the criteria.

     Supplier Selection. If Customer selects a seat or galley supplier that is
not on the Boeing recommended list, such seat or galley will become BFE and the
provisions of Exhibit A, Buyer Furnished Equipment Provisions Document, of the
AGTA will apply.

4.   Changes.

     After this Letter Agreement is signed, changes to SPE may only be made by
and between Boeing and the suppliers. Customer's contacts with SPE suppliers
relating to design (including selection of materials and colors), weights,
prices or schedules are for informational purposes only. If Customer wants any
changes made, requests must be made directly to Boeing for coordination with the
supplier.

5.   Proprietary Rights.

     Boeing's obligation to purchase SPE will not impose upon Boeing any
obligation to compensate Customer or any supplier for any proprietary rights
Customer may have in the design of the SPE.

6.   Remedies.

     If Customer does not comply with the obligations above, Boeing may:

          (i)  delay delivery of the Aircraft;

          (ii) deliver the Aircraft without installing the SPE;



P.A. No. 2021
Seller Purchased Equipment

2021-1
Page 4


          (iii) substitute a comparable part and invoice Customer for the cost;

          (iv)  increase the Aircraft Price by the amount of Boeing's additional
                costs attributable to such noncompliance.

7.   Customer's Indemnification of Boeing.

     Except as provided in Article 8.1.1 of AGTA-TLS, Customer will indemnify
and hold harmless Boeing from and against all claims and liabilities, including
costs and expenses (including attorneys' fees) incident thereto or incident to
successfully establishing the right to indemnification, 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 Aircraft (but not
the Aircraft before delivery), arising out of or in any way connected with any
nonconformance or defect in any SPE and whether or not arising in tort or
occasioned in whole or in part by the negligence of Boeing. This indemnity will
not apply with respect to any nonconformance or defect caused solely by Boeing's
installation of the SPE.

Subject:     Escalation Sharing

Reference:   Purchase Agreement No. 2021 (the Purchase Agreement) between 
             The Boeing Company (Boeing) and Atlas Air, Inc. (Customer)
             relating to Model 747-400F aircraft (the Aircraft)


This Letter Agreement amends and supplements the Purchase Agreement. All terms
used but not defined in this Letter Agreement have the same meaning as in the
Purchase Agreement.

1.   Commitment.

     Boeing agrees to share one-half of the escalation, up to a maximum of 3
percent per year, in each of the years 1997 and 1998 according to the terms in
paragraph 2 below. This applies to any of Customer's aircraft which are
scheduled to deliver after December 31, 1996. For the purpose of this Letter
Agreement such aircraft are referred to as "Eligible Aircraft."

All escalation calculations under this Letter Agreement will be made in
accordance with Exhibit D to the AGTA between Boeing and Customer, using actual
escalation indices published for the applicable period.

2.   Escalation Credit Memo.

     2.1. Calculation - Eligible Aircraft Delivering in 1997.

          At the time of delivery of each Eligible Aircraft delivering in 1997,
Boeing will issue to Customer a credit memorandum (the 1997 Credit Memorandum)
which will be applied to the Aircraft Price of such Eligible Aircraft. The 1997
Credit Memorandum is calculated as follows:


P.A. No. 2021
Escalation Sharing
<PAGE>   44
2021-3
Page 2

     One-half of the difference between the airframe and special features
     escalation calculated for a December 1996 aircraft delivery position, and
     the escalation calculated for the month of delivery of the 1997 Eligible
     Aircraft; provided however,

     The maximum amount of the 1997 Credit Memorandum does not exceed 3 percent
     pursuant to the following calculation:

     At the time of the delivery of the 1997 Eligible Aircraft, the Base
     Airframe Price and Special Features prices will be escalated to a December
     1996 delivery month. The December 1996 escalated price will be referred to
     in the following formula as the "December 1996 Index Amount". The 1997
     Credit Memorandum for the 1997 Eligible Aircraft will not exceed an amount
     equal to:

     the December 1996 Index Amount times 0.03

     2.2. Calculation - Eligible Aircraft Delivering in 1998.

          At the time of delivery of each Eligible Aircraft delivering in 1998,
Boeing will issue to Customer a credit memorandum (the 1998 Credit Memorandum)
which shall be applied to the Aircraft Price of such Eligible Aircraft. The 1998
Credit Memorandum shall be calculated as follows:

          (i) One-half of the difference between the airframe and special
features escalation calculated for a December 1997 aircraft delivery position,
and the escalation calculated for the month of delivery of the 1998 Eligible
Aircraft;

     provided however,

     The maximum amount of the 1998 Credit Memorandum shall not exceed 3 percent
     pursuant to the following calculation:

          At the time of the delivery of the 1998 Eligible Aircraft, the Base
          Airframe Price and Special Features prices will be escalated to a
          December 1997 delivery month. The December 1997 escalated price will
          be referred to in the following formula as the "December 1997 Index
          Amount." The 1998 Credit Memorandum for the 1998 Eligible Aircraft
          will not exceed an amount equal to:

          the December 1997 Index Amount times 0.03;




P.A. No. 2021

         and,

            (ii) The amount calculated above in paragraph 2.1 for the 1997
Credit Memorandum calculated through December, 1997.

     2.3.   Eligible Aircraft Delivering after 1998.

            For Eligible Aircraft delivering after the calendar year 1998, the
amount of the Credit Memorandum will be the amount calculated pursuant to
paragraph 2.2 above through December 1998. This credit memorandum amount will
be escalated from December 1998 to the month of delivery.

     2.4.   Advance Payment Base Price.

     It is agreed that the Advance Payment Base Prices for the Eligible Aircraft
set forth in the Purchase Agreement include an estimate for the escalation
sharing Credit Memorandum pursuant to this Letter Agreement.

3.   Escalating Credits (STE).

     It is agreed that the credit memoranda specified in Letter Agreement No.
6-1162-DSF-083 which is expressed as a percentage of the escalated Aircraft
Price of the Eligible Aircraft, will be calculated using the same factors used
to develop the adjusted airframe escalation pursuant to this Letter Agreement.

Subject:    Demonstration Flights

Reference:  Purchase Agreement No. 2021 (the Purchase Agreement) between
            The Boeing Company (Boeing) and Atlas Air, Inc. (Customer)
            relating to Model 747-400F aircraft (the Aircraft)

This Letter Agreement amends and supplements the Purchase Agreement. All terms
used but not defined in this Letter Agreement shall have the same meaning as in
the Purchase Agreement.

Definition of Terms:

Correction Costs: Customer's direct labor costs and the cost of any material
required to correct a Flight Discrepancy where direct labor costs are equal to
the warranty labor rate in effect between the parties at the time such labor is
expended.

Flight Discrepancy: A failure or malfunction of an Aircraft, or the accessories,
equipment or parts installed on the Aircraft which results from a defect in the
Aircraft, Boeing Product, engine or Supplier Product or a nonconformance to the
Detail Specification for the Aircraft.

The AGTA provides that each aircraft will be test flown prior to delivery for
the purpose of demonstrating the functioning of such Aircraft and its equipment
to Customer; however, Customer may elect to waive this test flight. For each
test flight waived, Boeing agrees to provide Customer an amount of jet fuel at
delivery that, in addition to the standard fuel entitlement, totals the
following amount of fuel:

Further, Boeing agrees to reimburse Customer for any Correction Costs incurred
as a result of the discovery of a Flight Discrepancy during the first flight of
the aircraft by Customer following delivery to the extent such Correction Costs
are not covered under a warranty provided by Boeing, the engine manufacturer or
any of Boeing's suppliers.

Should a Flight Discrepancy be detected by Customer which requires the return of
the Aircraft to Boeing's facilities at Seattle, Washington, so that Boeing may
correct such Flight Discrepancy, Boeing and Customer agree that title to and
risk of loss of such Aircraft will remain with Customer. In addition, it is
agreed that Boeing will have responsibility for the Aircraft while it is on the
ground at Boeing's facilities in Seattle, Washington, as is chargeable by law to
a bailee for mutual benefit, but Boeing shall not be chargeable for loss of use.

To be reimbursed for Correction Costs, Customer shall submit a written itemized
statement describing any flight discrepancies and indicating the Correction Cost
incurred by Customer for each discrepancy. This request must be submitted to
Boeing's Contracts Regional Director at Renton, Washington, within ninety (90)
days after the first flight by Customer.

         4.1. Boeing Spare Parts. Customer will place orders for Provisioning
Items by September 1, 1997; provided, however, that in those instances where
Boeing submits any revision to the Provisioning Data, Customer will place orders
for Boeing Spare Parts covered by such revision within 60 days following the
date of such submittal. At Customer's request, Boeing will process "controlled
shipments" by shipping full or partial quantities of an order on a schedule
specified by Customer, provided the final shipment is made no later han 24
months after receipt of the order.

         4.2. Vendor Provisioning Items. Customer may place orders with Boeing
for Provisioning Items which are manufactured by vendors or to their detailed
design and are covered by the Provisioning Data as initial provisioning for the
Aircraft. The price to Customer for any such vendor Provisioning Item will be
112% of the vendor's quoted price to Boeing therefor. If Customer elects to
purchase such vendor Provisioning Items from Boeing, Customer will place its
orders therefor in accordance with the provisions of Paragraph 4.1 above.

         4.3. Ground Support Equipment and Special Tools. Customer may place
orders with Boeing for ground support equipment (GSE) and special tools
manufactured by vendors which Customer determines it will initially require for
maintenance, overhaul and servicing of the Aircraft and/or engines. The price to
Customer for such GSE or special tools will be one hundred twelve percent (112%)
of the vendor's quoted price to Boeing therefor. If Customer elects to purchase
such GSE and special tools from Boeing, Customer will place its orders therefor
by the date set forth in Paragraph 4.1 above, or such later date as the parties
may mutually agree.

agrees to review such listing and indicate by marking on one copy of such
listing those components that Customer desires included in its QEC kits.
Customer will return such marked copy to Boeing within 30 days after Customer's
receipt of such listing. Within 30 days after Boeing's receipt of such marked
copy, Boeing will republish such listing to reflect only those components
selected by Customer and will provide copies of such republished listing to
Customer. Boeing will from time to time furnish revisions to such republished
listing until a date approximately 90 days after delivery of the last QEC kit
ordered by Customer for the Aircraft. Boeing will furnish to Customer as soon as
practicable a statement setting forth a firm price for the QEC kit configuration
selected by Customer. Customer agrees to place orders with Boeing for the QEC
kits for the Aircraft by July 1, 1997.

         4.6. Terms and Conditions. Applicable terms and conditions of the
Customer Services General Terms Agreement between Boeing and Customer, if
executed, or the standard terms and conditions on a Spares Customer Account
Terms and Conditions form will be applicable to Provisioning Items ordered by
Customer from Boeing for the Aircraft.

5.       Delivery.

         Boeing will, insofar as reasonably possible, deliver to Customer the
Spare Parts ordered by Customer in accordance with the provisions of this letter
on dates reasonably calculated to conform to Customer's anticipated needs in

initial deliveries and all subsequent deliveries of such Spare Parts will be as
mutually agreed between Boeing and Customer.

6.       Substitution for Obsolete Spare Parts.

         6.1. Obligation to Substitute. In the event that, prior to delivery of
the first Aircraft pursuant to the Purchase Agreement, any Spare Part purchased
by Customer from Boeing in accordance with this letter is rendered obsolete or
unusable due to the redesign of the Aircraft or of any accessory, equipment or
part therefor, (other than a redesign at Customer's request), Boeing will
deliver to Customer new and usable Spare Parts in substitution for such obsolete
or unusable Spare Parts and Customer will return the obsolete or unusable Spare
Parts to Boeing. Boeing will credit Customer's account with Boeing with the
price paid by Customer for any such obsolete or unusable Spare Part and will
invoice Customer for the purchase price of any such substitute Spare Part
delivered to Customer.

         6.2. Delivery of Obsolete Spare Parts and Substitutes Therefor.
Obsolete or unusable Spare Parts returned by Customer pursuant to Paragraph 6
will be delivered to Boeing at its Seattle Distribution Center, or such other
destination as Boeing may reasonably designate. Spare Parts substituted for such
returned obsolete or unusable Spare Parts will be delivered to Customer at
Boeing's Seattle Distribution Center, or such other Boeing shipping point as
Boeing may reasonably designate. Boeing will pay the freight charges for
shipment from Customer to Boeing of any such obsolete or unusable Spare Part and
for shipment from Boeing to Customer of any such substitute Spare Part.

7.       Repurchase of Provisioning Items.

         7.1. Obligation to Repurchase. During a period commencing 1 year after
delivery of the first Aircraft under the Purchase Agreement, and ending 5 years
after such delivery, Boeing will, upon receipt of Customer's written request and
subject to the exceptions in Paragraph 7.2 below, repurchase unused and
undamaged Provisioning Items which (i) were recommended by Boeing in the
Provisioning Data as initial provisioning for the Aircraft, (ii) were purchased
by Customer from Boeing, and (iii) are surplus to Customer's needs.

         7.2. Exceptions. Boeing will not be obligated under Paragraph 7.1
above, to repurchase any of the following: (i) quantities of Provisioning Items
in excess of those quantities recommended by Boeing in the Provisioning Data for

Subject:          Multiple Aircraft Operating Weights

Reference:        Purchase Agreement No. 2021 (the Purchase Agreement) between
                  The Boeing Company (Boeing) and Atlas Air, Inc. (Customer)
                  relating to Model 747-400F aircraft (the Aircraft)

This Letter Agreement amends and supplements the Purchase Agreement. All terms
used but not defined in this Letter Agreement have the same meaning as in the
Purchase Agreement.

In this Letter Agreement, the term "Aircraft" means all Model 747-400F aircraft
that Customer legally owns or directly manages, whether purchased by Customer
under the Purchase Agreement or otherwise. It does not include any aircraft
which Customer may have obtained through an operating lease.

1.       Operation at Multiple Gross Weights.

Customer has requested and Boeing agrees to provide the required documentation
to allow the operation of the Aircraft at alternate Maximum Take-Off Weights
(MTOW). Boeing will provide an FAA approved Airplane Flight Manual such that
each Aircraft will include a basic MTOW of 850,000 pounds and two alternate MTOW
of 875,000 pounds and 800,000 pounds in appendices to the Airplane Flight
Manual. Customer may operate the Aircraft at the weights provided at Customer's
sole discretion as long as the annual average operational weight of the
Customer's fleet does not exceed 850,000 pounds. It will be the responsibility
of Customer to obtain concurrence of the cognizant aviation authority to use the
Airplane Flight Manual and its appendices.

2.       Payment Amounts.

Customer will pay to Boeing the amount of $[ ] ([ ]$ U.S. Subject to Escalation)
per Aircraft for this capability upon the delivery by Boeing of the Airplane
Flight Manual appendices described above. The weights and price shown above were
derived using the methods illustrated in Attachment A.

3.       Annual MTOW Use Report.

One year after the signing date of this Letter Agreement, and thereafter on an
annual basis, Customer will furnish to Boeing a MTOW Use Report signed by an
officer of Customer which reports the actual operating weights of the Aircraft
affected by this Letter Agreement in the previous year. If the actual
operational average gross weight utilization is greater than the average gross
weight purchased under this Letter Agreement, Customer will pay Boeing's then
current price per pound of difference above the average gross weight utilization
projected for the year for each Aircraft. If the actual operational average
gross weight utilization is less than the average gross weight projected under
this Letter Agreement or the MTOW Use Reports, no monetary credit will be given
to Customer for the difference.

4.       Sale or Lease of Aircraft by Customer.

         Concurrent with Customer's written notification to Boeing of its intent
to sell or lease one or more of its Aircraft (Disposed Aircraft) to a third
party (other than a subsidiary or affiliate of Customer,) Customer will elect
one of the following options with respect to each of the Disposed Aircraft:

         4.1. Upon request Boeing will, at no charge to Customer, provide
documentation to limit a Disposed Aircraft's certified MTOW to the one certified
MTOW which will be the average gross weight value applicable as of the date of
Customer's request; or

         4.2. If Customer desires to sell or lease a Disposed Aircraft certified
to operate at a higher MTOW than that specified in Paragraph 4.1, then Customer
may purchase, at Boeing's then current price for MTOW, the difference in pounds
between the average gross weight value applicable as of the date of Customer's
request and the MTOW desired, for a Disposed Aircraft; or

         4.3. If Customer desires to sell or lease a Disposed Aircraft certified
to operate at a lower MTOW than that specified in Paragraph 4.1, then Boeing
will, without charge or credit, provide documentation to limit a Disposed
Aircraft's certified MTOW to such lower value.

       Calculation Method for Average Gross Weight and Price per Aircraft

Customer has agreed to purchase an average gross weight based on expected use of
each Aircraft within Customer's specific minor model fleet. An average gross
weight utilization will be calculated and charged against every Aircraft in that
minor model fleet. The minimum gross weight for any individual Aircraft in the
average calculation shall be the basic gross weight.

The price per Aircraft for the average gross weight was calculated as follows:

                 PM = (NT * WA * PW) - (NE * WE * PW)
                       -----------------------------
                                    NT

The following definitions apply:

   PM = Purchase Price of Multiple Operating Weight per aircraft 
   NT = Total number of aircraft in Customer's fleet including the Aircraft 
   WA = Weighted Average minus the basic weight (in pounds) per minor model
        fleet 
   PW = Boeing's current price per pound for MTOW increases 
   NE = Number of previously purchased minor model aircraft in
        Customer's fleet
   WE = Total gross weight (in pounds) in excess of basic gross weight
        previously purchased for NE aircraft

Example Calculation of Average Gross Weight

Customer owns ten 757-200 aircraft currently at 230,000 pounds MTOW, each of
which had a basic gross weight of 220,000 pounds at initial purchase, and is
purchasing five additional 757-200's. Therefore, NT = 15

Step 1. Determine routes to be flown in the upcoming year for all 15 aircraft,
and determine the MTOW needed to support each planned route.

          27% of routes require 220,000 pounds or less 
          50% of routes require 230,000 pounds 
          23% of routes require 240,000 pounds


P.A. No. 2021

<PAGE>   62
Atlas Air, Inc.
Attachment A to Letter Agreement 2021-6
Page 2


Step 2.  Convert percentage of routes into Aircraft.

                  15 aircraft * 27% = 4.05 aircraft, round to  4
                  15 aircraft * 50% = 7.50 aircraft, round to  8
                  15 aircraft * 23% = 3.45 aircraft, round to  3
                                      -----                   --
                                    15 aircraft               15

Step 3.  Calculate weighted average of the entire minor model fleet

                  4 * 220,000 =    880,000
                  7 * 230,000 = 1,840,000
                  3 * 240,000 =    720,000
                                ----------
                      Total Weight   3,440,000 / 15 aircraft = 229,333 pounds, 
                      or 9,333 pounds above base MTOW per aircraft.

                      WA = 9,333 pounds

Step 4. Multiply NT times WA times current Boeing price per pound (PW).

                  15 * 9,333 * $55.22(1995$) = $7,730,524

Step 5. Determine value of weight previously purchased for the existing fleet,
by multiplying 10 Aircraft (NE) times 10,000 pounds (WE) times PW.

                  10 * 10,000 * $55.22(1995$) = $5,522,000

Step 6. Subtract the results in Step 5 from that of Step 4, and divide the
result by NT to determine Purchase Price of Multiple Operating Weight (PM).

                           $7,730,524 - $5,522,000 = $2,208,524
                         PM = $2,208,524/ 15 aircraft
                         PM = $147,200 per aircraft (Rounded to nearest $100)

4.                AIRCRAFT CONFIGURATION

4.1.              The guarantees contained in this Attachment are based on the
                  Aircraft configuration as defined in the original release of
                  Detail Specification D019U002 (hereinafter referred to as the
                  Detail Specification). Appropriate adjustment shall be made
                  for changes in such Detail Specification approved by the Buyer
                  and Boeing or otherwise allowed by the Purchase Agreement
                  which cause changes to the flight performance and/or weight
                  and balance of the Aircraft. Such adjustment shall be
                  accounted for by Boeing in its evidence of compliance with the
                  guarantees.

                  The Manufacturer's Empty Weight guarantee of Section 3 will be
                  adjusted by Boeing for the following in its evidence of
                  compliance with the guarantees:

                  (1) Changes to the Detail Specification including Change
                  Requests, Master Changes, Change Orders or any other changes
                  mutually agreed upon between the Buyer and Boeing or otherwise
                  allowed by the Purchase Agreement.

                  (2) The difference between the component weight allowances
                  given in Appendix IV of the Detail Specification and the
                  actual weights.

5.                GUARANTEE CONDITIONS

                  5.1.     All guaranteed performance data are based on the ICAO
                           International Standard Atmosphere (ISA) and specified
                           variations therefrom; altitudes are pressure
                           altitudes.

                  5.2.     The FAA Regulations (FAR) referred to in this
                           Attachment are, unless otherwise specified, the
                           747-400 Certification Basis regulations specified in
                           the Type Certificate Data Sheet A20WE, Revision B,
                           dated June 8, 1989.

                  5.3.     Requirement, or in the interpretation of any such
                           law, governmental regulation or requirement that
                           affects the certification basis for the Aircraft as
                           described in Paragraph 5.2, and as a result thereof,
                           a change is made to the configuration and/or the
                           performance of the Aircraft in order to obtain
                           certification, the guarantees set forth in this

                    Attachment shall be appropriately modified to reflect any 
                    such change.

               5.4. The takeoff portion of the mission guarantees are based on
                    hard surface, level and dry runways with no wind or
                    obstacles, no clearway or stopway, 235 mph tires, with
                    anti-skid operative, and with the Aircraft center of gravity
                    at the most forward limit unless otherwise specified. The
                    takeoff performance is based on no engine bleed for air
                    conditioning or thermal anti-icing and the Auxiliary Power
                    Unit (APU) turned off. The improved climb performance
                    procedure will be used for takeoff as required.

               5.5. The climb, cruise and descent portions of the mission
                    guarantees include allowances for normal power extraction
                    and engine bleed for normal operation of the air
                    conditioning system. Normal electrical power extraction
                    shall be defined as not less than a 100 kilowatts total
                    electrical load. Normal operation of the air conditioning
                    system shall be defined as pack switches in the "Normal"
                    position, the temperature control switches in the "Auto"
                    position that results in a nominal cabin temperature of
                    75 degrees F, and all air conditioning systems operating
                    normally. This operation allows a maximum cabin pressure
                    differential of 8.9 pounds per square inch, with a nominal
                    Aircraft cabin ventilation rate of 5,600 cubic feet per
                    minute including passenger cabin recirculation. The APU is
                    turned off unless otherwise specified.

               5.6. The climb, cruise and descent portions of the mission
                    guarantees are based on an Aircraft center of gravity
                    location of 20 percent of the mean a aerodynamic chord.

               5.7. Performance, where applicable, is based on a fuel Lower
                    Heating value (LHV) of 18,580 BTU per pound and a fuel
                    density of 6.75 pounds per U.S. gallon.

6.                GUARANTEE COMPLIANCE

                  6.1.     Compliance with the guarantees of Sections 2 and 3
                           shall be based on the conditions specified in those
                           sections, the Aircraft configuration of Section 4 and
                           the guarantee conditions of Section 5.

                           established by calculations based on flight test data
                           obtained from an aircraft in a configuration 4,
                           similar to that defined by the Detail specification.

                  6.4.     The OEW used for compliance with the mission
                           guarantees shall be the actual MEW plus the Standard
                           and Operational Items Allowance in Paragraph 3-60-0
                           of the Detail Specification.

                  6.5.     Compliance with the Manufacturer's Empty Weight
                           guarantee shall be based on information in the

Subject:          Aircraft Maintenance Cost Protection Program

Reference:        Purchase Agreement 2021 (the Purchase Agreement) between
                  The Boeing Company (Boeing) and Atlas Air, Inc. (Customer)
                  relating to Model 747-400F aircraft (the Aircraft)

This Letter Agreement amends the Purchase Agreement and Exhibit C of the AGTA.
All terms used but not defined in this Letter Agreement have the same meaning as
in the Purchase Agreement and AGTA.

In consideration of Customer's purchase of the Aircraft and in response to
Customer's request for contractual assurances regarding Aircraft maintenance
costs, Boeing agrees to amend Exhibit C (Product Assurance Document) of the AGTA
to include the aircraft maintenance material cost protection program described 
herein (the Program).

1.   Scope.

     1.1. Covered Aircraft.

     The Program applies to each of the Aircraft while operated by Customer on
Customer's routes during the Program Term, as defined in paragraph 1.2 below,
(the Covered Aircraft).

     1.2. Program Term.

          The term of the Program will be 10 consecutive years commencing on the
first day of the calendar quarter in which the first Covered Aircraft is
delivered by Boeing to Customer (Program Term).

     1.3. Covered Maintenance Work.

          The Program applies to materials consumed in the maintenance of the
airframe and component elements of the Covered Aircraft which are included in
aircraft systems 5, 7 through 11, relevant sections of 12 and 20, 21 through 57,

"Specification for Manufacturer's Technical Data," dated 1984) when such
maintenance is performed in accordance with Customer's FAA approved maintenance
program and such materials are properly charged to the following work
descriptions:

     (i) Scheduled Checks: All routine and required non-routine or corrective
maintenance performed by Customer during scheduled checks.

     (ii) Non-scheduled Maintenance: All non-scheduled required maintenance.

     (iii) Repair and Overhaul: Any required repair or overhaul of rotable or
repairable systems, accessories, equipment and parts.

     (iv) Modifications: Modifications required to make changes recommended by
Boeing or Boeing suppliers pursuant to paragraphs 5.1 and 7.1 herein.

The Program applies only to the maintenance described above (Airframe
Maintenance) and does not apply to materials consumed with respect to Engines,
as defined in Exhibit EE1 to the Purchase Agreement.

2.   Basic Definitions.

     2.1. "Fleet," for any Reporting Period, means the number of Covered
Aircraft operated by Customer on Customer's routes during such Reporting Period.

     2.2. "Fleet Hours," for any Reporting Period, means the total airborne time
(aircraft takeoff to touchdown) accumulated by the Covered Aircraft during such
Reporting Period.

     2.3. "Reporting Period" is a 12 month period commencing on either the date
the Program Term commences or on an anniversary thereof.

3.   Maintenance Material Cost Program Measures.

     3.1. Airframe Maintenance Material Cost.

     "Airframe Maintenance Material Cost" is the actual cost paid by Customer
for materials required to perform the Aircraft Maintenance, whether performed




P.A No. 2021
Maint Cost Protection

Page 3


by Customer or by others for Customer, exclusive of any surcharges, taxes,
duties, tariffs, interest or other similar charges added to the manufacturer's
standard price.

     3.2. Cumulative Average Reported Material Cost.

     The "Cumulative Average Reported Material Cost" or "Average Reported Cost,"
for any Reporting Period, is calculated as the aggregate Airframe Maintenance
Material Cost for all then-completed Reporting Periods divided by the Fleet
Hours for all such completed Reporting Periods.

     3.3. Target Material Cost.

     The "Target Material Cost" for the Covered Aircraft for any Reporting
Period is the projected net cost to Customer for materials set forth in
paragraph 3.1 above where such Target will be expressed as a dollar value per
flight hour.

          3.3.1. The Target Material Cost in year 1996 dollars is based on a
projected average airborne time per flight for the fleet of 9.0 hours (Projected
Average Flight Time), as follows:

          3.3.2.   The Target Material Cost for any Reporting Period will be 
adjusted for changes in material costs based on the following:
                  
                   3.3.2.1 To reflect changes in inflation rates, the Target 
Material Cost for such Reporting Period will be calculated by multiplying the 
base Target Material Cost by the arithmetic average of the 12 monthly Producer 
Price Indexes for "Aircraft parts and auxiliary equipment, n.e.c.," (Standard 
Industrial Classification Code 3728) for such Reporting Period and dividing the
result by the arithmetic average of such Indices for the year 199X.

(The index described in this paragraph 3.3.2.1 will be obtained from the
publication "Producer Prices and Price Indexes" published by the U.S. Department
of Labor, Bureau of Labor Statistics or any comparable successor publication
published by the U.S. Department of Labor, Bureau of Labor Statistics or any
comparable successor agency).

                   3.3.2.2 If the actual average airborne time per flight for
the  Fleet (Actual Average Flight Time) for any Reporting Period is different
from the Projected Average Flight Time of 9.0 hours, the Target Material Cost
for such Reporting Period will be adjusted to reflect such Actual Average
Flight Time for such Reporting Period in accordance with Attachment A to this
Program.
                                                                              
                   3.3.2.3 The Target Material Cost is based on (i) the number
of  Covered Aircraft and the delivery schedule for such Covered Aircraft set
forth in the Agreement and (ii) a projected average utilization for the Covered
Aircraft during any Reporting Period of 5,100 flight hours. If the number of
Covered Aircraft or their delivery schedules are revised prior to or during the
Program Term as provided under or by amendment to the Agreement or the average
utilization for the Covered Aircraft during any Reporting Period exceeds 5,400
or is less than 4,800 flight hours, Boeing will have the right to revise the
Target Material Cost to reflect the impact of any such revisions or excess.   

     3.4. Cumulative Average Target Material Cost.

          The "Cumulative Average Target Material Cost" or "Cumulative Average 
Target Cost" as of any Reporting Period means (i) the sum of the products of
the Target Material Cost for each completed Reporting Period multiplied by the
Fleet Hours for



P.A. No. 2021
Maint. Cost Protection
<PAGE>   92


Atlas Air, Inc.

each such completed Reporting Period (ii) divided by the total Fleet Hours for
all completed Reporting Periods.

4.   Deficiency.

     A "Deficiency" with respect to Airframe Maintenance Material Cost occurs
when the Cumulative Average Reported Cost for a Reporting Period exceeds [ ]% of
the Cumulative Average Target Cost as of such Reporting Period, all as may be
adjusted pursuant to the terms of the Program.

5.   [               ]

     5.1. If a [          ] exists, and Customer provides its reports to Boeing
pursuant to paragraph 6 herein, then Boeing will:

                  (i)      [                     ]

                  (ii)     [                     ]

                  [   ]

6.   Administrative Requirements.

     6.1. Customer will report to Boeing, within 90 days after the last day of
each Reporting Period, (i) the Cumulative Average Reported Cost broken down by
scheduled maintenance costs, non-scheduled maintenance costs, repair and
overhaul costs and modification costs, (ii) the Actual Average Flight Time for
the Fleet and (iii) the number of Covered Aircraft included in the Fleet.
Failure to file such reports within such 90 day period will constitute an
acknowledgment by Customer that there was no [ ] for that Reporting Period and
Boeing will not be obligated to provide any of the remedies arising under this
Program. However, if [ ] occurs, Customer will, within 90 days after the last
day of the applicable Reporting Period, report to Boeing the data identified
above for all then-completed Reporting Periods of the Program Term.

     6.2. Customer's reports will include sufficient data to substantiate any
claimed [ ]. Upon request, Customer will submit to Boeing reasonable proof of
the existence of any Airframe Maintenance Material Cost claimed by Customer as
the basis of a Deficiency under the terms of this Program. Customer will
maintain and submit to Boeing such records, data and reports as may reasonably
be required to (i) determine cost elements

                           Seattle, Washington  98124-2207

7.   Conditions and Limitations.

     7.1. If Boeing or any Boeing supplier issues no-charge service bulletins or
service bulletins with no-charge retrofit kits which would reduce Airframe
Maintenance Material Cost, Customer will make any changes recommended by such
service bulletins and install such retrofit kits within 240 days after issuance
of such instructions or receipt of such kits at Customer's facility, or such
longer period as may be mutually agreed by the parties. In the event of
Customer's failure to comply with the time requirements of this paragraph 7.1,
all Airframe Maintenance Material Cost which would have been eliminated if such
service bulletins or retrofit kits had been incorporated, as determined by
Boeing, will be subtracted from Cumulative Average Reported Cost reported after
expiration of such time requirements.

     7.2. Customer will promptly notify Boeing in writing of any existing or
contemplated variations in its maintenance cost accounting system or procedures
which affect or would affect the proper reporting of Airframe Maintenance
Material Cost. Boeing will have the right to adjust the Cumulative Average
Target Cost and the definition for Airframe Maintenance Material Cost to reflect
the effect of any such variations.

     7.3. Boeing will have the right to audit and investigate all costs charged
by Customer to the "Work Descriptions" listed in paragraph 1.3 herein, as well
as the mainte-

enance practices and procedures related thereto, at any reasonable time during
the Program Term. Boeing will also have the right to disapprove costs improperly
charged to such Work Descriptions. Boeing will provide Customer with written
notification of its disapproval of any such costs, and if Customer does not
provide proof that such costs are properly chargeable to such Work Descriptions
within 60 days after such notification, Boeing and Customer will determine the
amount to be deducted from the computation of the Average Reported Cost.

     7.4. Boeing will have the right at all reasonable times to inspect and
review Customer's maintenance facilities, programs and procedures. If Boeing
recommends in writing reasonable changes in Customer's maintenance programs and
procedures which would reduce the Average Reported Cost and offers reasonable
proof that such changes will reduce such costs and Customer does not effect such
changes or Customer delays effecting such changes beyond the period set forth in
paragraph 7.1 herein, Boeing will have the right to adjust the Cumulative
Average Target Cost to reflect the increased costs which Boeing estimates will
result from Customer's failure or delay in effecting such changes.

     7.5. The Airframe Maintenance Material Cost will not include the following:
costs arising from loss of, or damage to, any Covered Aircraft, or any
accessory, equipment or part thereof; any taxes, duties, tariffs, surcharges,
transportation, interest or overhead; the cost of initial or sustaining spare
parts or the depreciation of such spare parts; costs resulting from any
modification to the Covered Aircraft or any equipment, accessory or part thereof
other than modifications described under paragraph 1.3(iv) herein; costs
resulting from the negligent acts or omissions of Customer; costs resulting from
the improper operation, service, maintenance or overhaul of any Covered
Aircraft, or any system, accessory, equipment or part thereof; costs
attributable to loss of use, revenue or profit; costs of consumable fluids,
including fuel; costs due to acts of God, war, warlike operations,
insurrections, riots, fires, floods, explosions, accidents, epidemics or
quarantine restrictions; costs due to Government priorities, allocation
regulations or orders which affect materials or facilities needed for the
maintenance of Covered Aircraft; costs due to strikes or labor troubles causing
cessation, slowdown or interruption of work related to the maintenance of
Covered Aircraft; delay in transportation or inability to procure materials,
accessories, equipment or parts needed for the maintenance of Covered Aircraft;
or any other costs not included in Airframe Maintenance Material Cost as defined
in paragraph 3.1 herein.

     7.6. Customer's Cumulative Average Reported Cost as of any Reporting Period
will be reduced by any of the following items to the extent that such items have
been included as part of such Cumulative Average Reported Cost:



P.A. No. 2021

                 (i) the price for any part provided by Boeing or Boeing's
suppliers to Customer at no charge,   

                 (ii) an amount equal to the difference between the

reported price for any part and the reduced price for such part as provided by
Boeing or Boeing's suppliers to Customer,

                 (iii) the amount of any credit memorandum or other payment
scheme, established in Customer's favor, related to the materials involved in
any warranty, maintenance material cost guarantee or similar agreement and
issued by Boeing or Boeing suppliers to Customer.

     7.7. The Program will be suspended if during any Reporting Period the
average utilization for the Covered Aircraft is below 1,400 flight hours. Once
the average utilization for the Covered Aircraft exceeds the minimum average
utilization set forth above during any subsequent Reporting Period, the Program
will be resumed commencing on the first day of such subsequent Reporting Period.
Customer's report of Cumulative Average Reported Cost as of any Reporting Period
during the Program Term will exclude all Airframe Maintenance Material Cost
incurred and Fleet Hours accumulated by Customer during any Reporting Period in
which the Program was suspended as provided above. The Program will not be
extended to reflect any period wherein it was suspended.

     7.8. At Boeing's request, Customer will assign to Boeing, any of Customer's
rights against the manufacturer of any equipment, accessory or part installed in
the Covered Aircraft as Boeing may reasonably require to fulfill its obligations
with respect to any remedy provided by Boeing hereunder.

     7.9. THIS LETTER AGREEMENT AND THE RIGHTS AND REMEDIES OF CUSTOMER AND
OBLIGATIONS OF BOEING HEREIN ARE SUBJECT TO THE DISCLAIMER AND RELEASE AND
EXCLUSION OF CONSEQUENTIAL AND OTHER DAMAGES PROVISIONS OF ARTICLE 12 OF THE
AGREEMENT.

For the purpose of this paragraph, the term "Boeing" means The Boeing Company,
its division, subsidiaries and affiliates, the assignees of each, and their
directors, officers, employees and agents.

configuration for the Covered Aircraft as set forth in Detail Specification
D-TBD dated TBD (Exhibit A to the Purchase Agreement). Such target material cost
may be equitably adjusted by mutual agreement to appropriately reflect any
changes to the actual configuration of the Covered Aircraft at the time of
delivery thereof to Customer. Equitable adjustments to such target material cost
may also be made by mutual agreement at any time during the Program Term to
reflect any additional changes in the configuration of the Covered Aircraft.

9.   Duplicate Product Assurance Remedies.

     It is agreed that Boeing will not be obligated to provide to Customer any
remedy under this Program which is a duplicate of any other remedy which has
been provided to Customer under any Part of Exhibit C (Product Assurance
Document) to the AGTA.

10.  Confidential Treatment.

     Customer understands that certain commercial and financial information
contained in this Letter Agreement and attachment(s) hereto are considered by

Subject:   Open Configuration Matters

Reference: Purchase Agreement 2021 (the Purchase Agreement) between The Boeing
           Company (Boeing) and Atlas Air, Inc. (Customer) relating
           to Model 747-400F aircraft (the Aircraft)

This Letter Agreement amends the Purchase Agreement. All terms used but not
defined in this Letter Agreement have the same meaning as in the Purchase
Agreement.

1.   Aircraft Configuration.

     1.1. Initial Configuration. The initial configuration of Customer's Model
747-400F Aircraft has been defined by Boeing Model 747-400 Freighter Airplane
Configuration Specification D019U002 as described in Article 1 and Exhibit A of
the Purchase Agreement (the Aircraft Configuration). Given the long period of
time between the Purchase Agreement signing and delivery of the first Aircraft,
Customer may have the desire to incorporate certain configuration changes
(Options) into the Aircraft Configuration.

     1.2. Final Configuration Schedule. No later than 12 months prior to the
first Aircraft's scheduled delivery month, Boeing and Customer will discuss
potential Options. By May 16, 1997, Boeing will provide Customer with Option
proposals for those configuration changes that can be incorporated in Aircraft
production. By June 6, 1997, Customer will accept or reject these Options.

2.   Effect on Purchase Agreement.

     2.1. Basic Specification. Changes applicable to the basic Model 747-400F
aircraft which are developed by Boeing between the date of signing of the
Purchase Agreement and completion of the final configuration review described in
paragraph 1.2 above will be incorporated into the Aircraft Configuration by
written amendment.

     2.2. Exhibit A. The effects of all Options which are mutually agreed upon
between Boeing and Customer for incorporation into the Aircraft Configuration
will be incorporated into Exhibit A of the Purchase Agreement by written
amendment.

     2.3. Performance Guarantees. Within 60 days after Customer's acceptance of
any Options, Boeing will provide to Customer revisions to the Performance
Guarantees to reflect the effects, if any, of the incorporation of such Options
on Aircraft performance. Such revisions will be incorporated by written
amendment.

     2.4. Price Adjustments. The Aircraft Basic Price and Advance Payment Base
Price of each Aircraft included the amount of United States [ ] (95$) as an
estimate of the value of the Options which may be accepted and included in the
final Aircraft Configuration. The Aircraft Basic Price and the Advance Payment
Base Price of each Aircraft will be increased or decreased as required to
reflect the difference between such estimate and the actual prices plus any
required Seller Purchased Equipment, of the Options accepted by Customer.

3.   Purchase Agreement Amendment.

     Within 30 days after reaching agreement as to the final Aircraft
Configuration, Boeing will provide Customer an amendment to the Purchase
Agreement reflecting the effects of the configuration changes agreed to by the
parties.

         53.4         = The index of Commercial Jet fuel, Kerosene Base as
                      reflected in the Bureau of Labor Statistics, U.S.
                      Department of Labor "Producer Price Indexes" (Commodity
                      Code 05720301) for the month of July 1995 (1982 = 100).

(c)  In addition it is understood that at the time of [ ] calculation,
     Boeing may be unable to determine the precise amount of such value
     because the applicable fuel index used to determine Ca may not be
     released by the Bureau of Labor Statistics, or if released, it may be
     adjusted at a later date by such Bureau. Accordingly, the parties agree
     as follows:
     
          (i)  The commercial jet fuel index to be used in calculating the [ ]
               will be determined by utilizing the escalation provisions set
               forth above. The most current Bureau of Labor Statistics for the
               applicable month (including those noted as preliminary by the
               Bureau of labor statistics) and available to

                  Boeing at the time the escalation calculation is made shall be
                  used to calculate [ ]. If no value has been released for the
                  applicable year, the "preliminary" values first available for
                  the nearest preceding months will be used.

          (ii)     Subsequent to calculation of the [ ], Boeing may from time 
                   to time make adjustments to the value of the commercial jet 
                   fuel index for such [ ] to reflect any changes in index 
                   previously used to determine such [ ]. If the U.S. 
                   Department of Labor revises any previously released index 
                   value by removing or replacing such index, or by describing
                   such revision by footnote appendix or by any other method, 
                   the revised value shall be used to revise the value of the 
                   [ ]. Such adjustment(s) by Boeing, if any, shall be made 
                   within 12 months thereafter.                 

          (iii)    If the U.S. Department of Labor substantially revises the
                   methodology (in contrast to benchmark adjustments or other
                   corrections of previously released data) or discontinues
                   publishing the commercial jet fuel index, the parties shall
                   select a substitute for the revised or discontinued 
                   commercial jet fuel index, such substitute to lead in
                   application to the same adjustment result, insofar as
                   possible, as would have been achieved by continuing the use
                   of the original as it may have fluctuated had it not been
                   revised or discontinued. Appropriate revision of the formula
                   shall be made to accomplish this result. In the event
                   escalation provisions are made non enforceable or otherwise
                   rendered null and void by any agency of the United States
                   Government, the parties agree, to the extent they may
                   lawfully do so, to equitably adjust the price of any
                   affected ARV to reflect an allowance for increases in the
                   commercial jet fuel price.
        
     NOTE:         Any rounding of a number, as required under this Attachment
                   with respect to escalation of [ ], shall be accomplished as
                   follows: If the first digit of the portion to be dropped
                   from the number to be rounded is five or greater, the
                   preceding digit shall be raised to the next  higher number.

substitute for the advice of Customer's legal counsel.

         It is assumed and understood for purposes of this opinion, that the
delivery of the Aircraft is to be made to Customer in the State of Washington,
that title to the Aircraft will be either (i) transferred directly from Boeing
to Customer, and that the Aircraft is to be used by Customer in interstate and
foreign commerce for the transportation of property and persons for hire or (ii)
will be purchased by Customer or Customer's assignee solely for the purpose of
resale or lease, such resale or lease being in the regular course of Customer's
or Customer's assignee's business.

         Present Washington law exempts from the Washington State sales tax any:
"Sales of airplanes ... for use in conducting interstate or foreign commerce by
transporting therein or therewith property and persons for hire ...; component
part of such airplanes ... in the course of constructing, repairing, cleaning,
altering, or improving the same ..." RCW 82.08.0262.

         Present Washington law also exempts from the Washington State use tax:
"The use of any airplane ... used primarily in conducting interstate or foreign
commerce by trans-

Page 2


porting therein or therewith property and persons for hire ... and in respect to
use of tangible personal property which becomes a component part of any such
airplane ..." RCW 82.12.0254.

     By its definition, present Washington Law exempts from Washington State
Sales Tax: "Sales to a person who ... purchases for the purpose of resale as
tangible personal property in the regular course of business without intervening
use by such person...." RCW 82.04.050.

     Based on the foregoing, Boeing is of the opinion that under present law,
if the Exemption Certificate required by the rules of the Washington State Tax
Commission is given by Customer to Boeing, the sale of the Aircraft by Boeing
to Customer will not be subject to Washington sales or use tax, and Boeing need
not collect from Customer either a Washington sales tax or a Washington use tax
as a result of such sale.

     As of the date of this opinion, Boeing is not aware of any implemented or
pending Washington State legislation that will impose a sales, use, value added
or similar transfer tax on the Aircraft within the period contemplated for
delivery of the Aircraft.

2.       United States Taxes.

     As of the date of this opinion, under present United States law, the sale,
and use of aircraft are not subject to taxes nor is Boeing aware of any
implemented or pending legislation which will impose a sales, use, value added
or similar transfer tax on the Aircraft within the period contemplated for
delivery of the Aircraft.

Very truly yours,

THE BOEING COMPANY

            relating to Model 747-400F aircraft (the Aircraft)

This Letter Agreement amends and supplements the Purchase Agreement. All terms

                  1.1. Article 8.2.1 to AGTA-TLS, Insurance Requirements is
revised in its entirety to read: "The Customer will purchase and maintain
insurance [ ], and 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 the 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

the terms, limits, provisions and coverages required by this Article 8.2.1. The
failure of Boeing to demand compliance with

this 8.2.1 in any year will not in any way relieve Customer of its obligations
hereunder nor constitutes a waiver by Boeing of these obligations."

                  1.2. Exhibit A to AGTA-TLS, Buyer Furnished Equipment
Provisions Document, - Customer's configuration currently contains no items of
BFE. Should the configuration change to include any BFE, the Boeing BFE process
in place at that time will be the subject of discussion and negotiation between
Boeing and Customer.

                  1.3. Exhibit C to AGTA-TLS, Product Assurance Document, part
2, Article 4.5, Maximum Reimbursement is revised in its entirety to read:
"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 plus the
Direct Labor to remove and reinstall such Product."

                  1.4. Exhibit C to AGTA-TLS, Product Assurance Document, Part
2, Article 8.3.2, is revised in its entirety to read: "If Customer has a
critical parts shortage because Boeing has exceeded a Correction time objective
and Customer has procured spare Boeing Products for the defective Boeing Product
in quantities shown in Boeing's Recommended Spare Parts List (RSPL), [ ], then
Boeing will either expedite the Correction or provide a similar Product on a no
charge loan or lease basis until a Corrected Boeing Product is returned."

                  1.5. Letter Agreement 2021-1, paragraph 7, Customer's
Indemnification of Boeing, is revised in its entirety to read: "[ ] except as
provided in Article 8.1.1 of AGTA-TLS, Customer will indemnify and hold harmless
Boeing from and against all claims and liabilities, including costs and expense
(including attorneys' fees) incident thereto or incident to successfully
establishing the right to indemnification, 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 Aircraft (but not the Aircraft
before delivery), arising out of or in any way connected with any nonconformance
or defect in any SPE and whether or not arising in tort or occasioned in whole
or in part by the negligence of Boeing. This indemnity will not apply with
respect to any nonconformance or defect caused solely by Boeing's installation
of the SPE."

                  1.6. Exhibit C to AGTA-TLS, Part 2, Article 4.4, Credit Memo
Reimbursement, is revised in its entirety to read: "Boeing will make

memoranda which may be applied toward the purchase of Boeing goods and services.

     1.7. Customer will use its best efforts to have its insurance underwriters
accept the insurance provisions in Article 8.2 Insurance, of the AGTA. 
However, if Customer's insurance underwriters are unwilling to accept such
insurance provisions prior to the time such insurance is required of Customer,
the indemnity and insurance provisions in Attachment A hereto will supersede
Article 8.2.

     1.8. Letter Agreement 2021-5, paragraph 7.5, Price and Payment, is revised
in its entirety to read: "The price of each provisioning item repurchased by
Boeing pursuant to this paragraph 7 will be an amount equal to 100% of the
original invoice price thereof. In the case of Provisioning Items manufactured
by a vendor which were purchased pursuant to Paragraph 4, the repurchase price
will not include Boeing's 12% handling charge. Boeing will pay the repurchase
price by issuing a credit memorandum in favor of Customer which may be applied
against amounts due Boeing for the purchase of aircraft, Spare Parts, services
or the licensing of data, or at Customer's request. Boeing will make
reimbursement by check to Customer in an amount equal to the current net
repurchase price less any outstanding balance on Customer's account.

2.   Confidential Treatment.

     Customer understands that certain commercial and financial information
contained in this Letter Agreement are considered by Boeing as confidential.
Customer agrees that it will treat this Letter Agreement and the information
contained herein as confidential and will not, without the prior written consent
of Boeing, disclose this Letter Agreement or any information contained herein to
any other person or entity.

8.2  Customer's Indemnification of Boeing; Insurance.

        8.2.1   Customer's Indemnification of Boeing.

        Customer hereby indemnifies and holds harmless Boeing from and against
all claims and liabilities, including costs and expenses (including attorneys'
fees incident thereto) or incident to successfully establishing the right to
indemnification, 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 aircraft, arising out of or in any way related to
Materials provided by Boeing or the performance by Boeing of training, services
or other obligations pursuant to Exhibit B, Customer Support Document to the
AGTA, whether or not arising in tort or occasioned in whole or in part by the
negligence of Boeing.

        8.2.1.1  With regard to Materials, training, services and other
obligations, the foregoing indemnification will not apply to the 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.

        8.2.2  Customer's Insurance.

        Customer will cause Boeing to be named as an additional insured under

carriers to waive all rights of subrogation against Boeing to the extent of
Customer's above undertaking.

        8.2.2.1 Not later than 30 days prior to the scheduled delivery of the
first aircraft, Customer will furnish Boeing with certificates of insurance as
required by Boeing's then-standard practice, evidencing limits of liability
coverage and period of insurance, showing that Boeing has been named as an
additional insured, that insurance maintained by Customer will be primary and
not contributory with any insurance maintained by Boeing, and that subrogation
has been waived, and specifically referring to this Article 8.2.  Such
insurance certificates must reference all aircraft to be delivered or aircraft
to be used in connection with Boeing's performance of training, services or
other obligations under Exhibit B, Customer Support Document to the AGTA, or
separate certificates must be supplied for each such aircraft.  Such
certificates of insurance must be kept current and valid.

of its current insurance requirements to Customer.

        8.2.3   Definitions.

Boeing Company, its divisions, subsidiaries and affiliates, the assignees of
each, and their directors, officers, employees and agents.
