                                  THE COMPANY
 
We are the world's largest air cargo outsourcer, with an all Boeing fleet of 747
freighter aircraft that comply with Stage 3 FAA noise regulations. We provide
reliable airport-to-airport cargo transportation services throughout the world
to major international air carriers generally under three- to five-year
fixed-rate U.S. dollar denominated contracts which typically require that we
supply aircraft, crew, maintenance and insurance. Our customers currently
include China Airlines Ltd., British Airways World Cargo, Scandinavian Airlines
System, The International Airline of the United Arab Emirates, Thai Airways
International Public Company Limited, Fast Air Carrier, S.A., Lineas Aereas
Suramericanas, S.A., Cargolux Airlines International, S.A., Linee Aeree Italiane
S.p.A., Iberia Airlines of Spain, El Al Israel Airlines Ltd. and Federal Express
Corporation. We provide efficient, cost effective service to our customers
primarily as a result of our productive work force, the outsourcing of a
significant part of our regular maintenance work on a long-term, fixed-cost
contractual basis and the advantageous cost economies realized in the operation
of our fleet, comprised solely of Boeing 747 aircraft which are configured for
service in long-haul cargo operations.
 
Atlas is incorporated under the laws of the State of Delaware. Our principal
executive offices are located at 538 Commons Drive, Golden, Colorado 80401, and

                                USE OF PROCEEDS
 
Except as otherwise provided in the applicable Prospectus Supplement, the net
proceeds to the Company from the sale of the Securities offered hereby will be
available for general corporate purposes, including, but not limited to,
repayment of short-term or long-term indebtedness, capital expenditures,
repurchases of common stock and acquisitions. The Company will not receive any
of the proceeds from the sale of Common Stock by any selling stockholders.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
The ratio of earnings to fixed charges represents the number of times that fixed
charges were covered by earnings. For purposes of computing the ratio of
earnings to fixed charges,
 
                                        2
<PAGE>   7
 
"earnings" consists of income (loss) prior to income tax benefit (expense), as
adjusted to exclude the "Write-off of capital investment and other" in the
second quarter of 1997, and fixed charges (excluding capitalized interest for
the period). "Fixed charges" consist of interest expense (including amounts
capitalized), amortization of debt issuance costs and one-third of rental
payments on operating leases (such one-third portion having been deemed by us to
represent the interest portion of such payments). The table below presents the
ratio of earnings to fixed charges for the years ended December 31, 1993, 1994,
1995, 1996 and 1997 and the nine months ended September 30, 1997 and 1998.

and the exchange of and the transfer of Debt Securities will be registrable, at
the office or agency of the Company in Golden, Colorado maintained for such
purpose and at any other office or agency maintained for such purpose, except
that, at the option of the Company, interest may be paid by mailing a check to
the address of the Person entitled thereto as it appears on the Security
Register. (Section 301, 305 and 1002) Unless otherwise indicated in the
applicable Prospectus Supplement, the Debt Securities will be issued in
denominations of $1,000 or integral multiples thereof. (Section 302) No service
charge will be made for any registration or transfer or exchange of the Debt
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge imposed in connection therewith. (Section 305)
 
All monies paid by the Company to a Paying Agent for the payment of principal
or, premium, if any, or interest on any Debt Security which remain unclaimed for
two years after such principal, premium or interest has become due and payable
may be repaid to the Company and thereafter the Holder of such Debt Security may
look only to the Company for payment thereof. (Section 1003)
 
BOOK-ENTRY DEBT SECURITIES
 
The Debt Securities of a series may be issued in the form of one or more Global
Securities that will be deposited with a Depositary or its nominee identified in
the applicable Prospectus Supplement. In such a case, one or more Global
Securities will be issued in a denomination or aggregate denominations equal to
the portion of the aggregate principal amount of Outstanding Debt Securities of
the series to be represented by such Global Security or Securities. Unless and
until it is exchanged in whole or in part for Debt Securities in registered
form, a Global Security may not be registered for transfer or exchange except as
a whole by the Depositary for such Global Security to a nominee of such
Depositary and except in the circumstances described in the applicable
Prospectus Supplement. (Section 204 and 305)
 
The specific terms of the depositary arrangement with respect to any portion of
a series of Debt Securities to be represented by a Global Security will be
described in the applicable Prospectus Supplement. The Company expects that the
following provisions will apply to depositary arrangements.
 
Unless otherwise specified in the applicable Prospectus Supplement, Debt
Securities which are to be represented by a Global Security to be deposited with
or on behalf of a Depositary will be represented by a Global Security registered
in the name of such Depositary or its nominee. Upon the issuance of such Global
Security, and the deposit of such Global Security with or on behalf of the
Depositary for such Global Security, the Depositary will credit, on its
book-entry registration and transfer system, the respective principal amounts of
the Debt Securities represented by such Global Security to the accounts of
institutions that have accounts with such Depository or its nominee
("participants"). The accounts to be credited will be designated by the
underwriters or agents of such Debt Securities or by the Company, if such Debt
Securities are offered and sold directly by the Company. Ownership of beneficial
interest in such Global Security will be limited to participants or Persons that
may hold interest through participants. Ownership of beneficial interests by
participants in such Global Security will be shown on, and the transfer of that
ownership interest will be effected only through, records
 
                                        5
<PAGE>   10
 
maintained by the Depositary or its nominees for such Global Security. Ownership
of beneficial interests in such Global Security by Persons that hold through
participants will be shown on, and the transfer of that ownership interest
within such participant will be effected only through, records maintained by
such participant. The laws of some jurisdictions require that certain purchasers
of securities take physical delivery of such securities in certificated form.
The foregoing limitations and such laws may impair the ability to transfer
beneficial interests in such Global Securities.
 
So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will considered the sole owner or Holder of the Debt Securities
otherwise represented by such Global Security for all purposes under the
Indenture. Unless otherwise specified in the applicable Prospectus Supplement,
owners of beneficial interests in such Global Security will not be entitled to
have Debt Securities of the series represented by such Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of Debt Securities of such series in certificated form and will not be
considered the Holders thereof for any purposes under the Indenture. (Section
204 and 305) Accordingly, each Person owning a beneficial interest in such
Global Security must rely on the procedures of the Depositary and, if such
Person is not a participant, on the procedures of the participant through which
such Person owns its interest, to exercise any rights of a Holder under the
Indenture. Payments, transfers, exchanges and other matters relating to
beneficial interests in a Global Security may be subject to various policies and
procedures adopted by the Depositary from time to time. None of the Company, the
Trustee or any agent of the Company or the Trustee will have any responsibility
or liability for any aspect of the Depositary's or any participant's records
relating to, or for payments made on account of, beneficial interests in a
Global Security, or for maintaining, supervising or reviewing any records
relating to such beneficial interests.
 
The Indenture provides that the Depositary may grant proxies and otherwise
authorize participants to give or take any request, demand, authorization,
direction, notice, consent, waiver or other action which a Holder is entitled to
give or take under the Indenture. (Section 104) The Company understands that
under existing industry practices, if the Company requests any action of Holders
or an owner of a beneficial interest in such Global Security desires to give any
notice or take any action a Holder is entitled to give or take under the
Indenture, the Depositary would authorize the participants to give such notice
or take such action, and participants would authorize beneficial owners owning
through such participants to give such notice or take such action or would
otherwise act upon the instructions of beneficial owners owning through them.
 
Principal of, premium, if any, and interest on a Global Security will be payable
in the manner described in the applicable Prospectus Supplement.
 
EVENTS OF DEFAULT
 
Unless otherwise specified in the applicable Prospectus Supplement, the
following are Events of Default under the Indenture with respect to Debt
Securities of any series: (a) failure to pay principal of or premium, if any, on
any Debt Security of that series when due, continued for five Business Days; (b)
failure to pay any interest on any Debt Security of that series when due,
continued for 30 days; (c) failure to perform any other covenant of the Company
in the Indenture (other than a covenant included in the Indenture solely for the
benefit of a series of Debt Securities other than that series), continued for 60
days after written notice as provided in the Indenture; (d) a default under
 
                                        6
<PAGE>   11
 
any evidence of indebtedness for money borrowed by the Company or a Restricted
Subsidiary (including a default with respect to Debt Securities of any other
series) or under any instrument under which there may be issued or by which
there may be secured or evidenced any indebtedness for money borrowed by the
Company or a Restricted Subsidiary (including the Indenture), whether such
indebtedness exists as of the date of the Indenture or is thereafter created,
which default (i) results from the failure by the Company or any Restricted
Subsidiary to pay the principal amount due upon the final stated maturity of
such indebtedness in an amount in excess of $20 million after the expiration of
any applicable grace period, or (ii) results in the acceleration of such
indebtedness in an amount in excess of $20 million, in either case, without such
indebtedness having been discharged, or such acceleration having been rescinded
or annulled, within 10 days, after written notice to the Company by the Trustee
or by the Holders of at least 25% in principal amount of the Outstanding Debt
Securities of such series as provided in the Indenture; (e) certain events of
bankruptcy, insolvency or reorganization; and (f) any other Event of Default
provided with respect to Debt Securities of that series. (Section 501) If an
Event of Default with respect to Outstanding Debt Securities of any series shall
occur and be continuing, either the Trustee or the Holders of at least 25% in
principal amount of the Outstanding Debt Securities of that series by notice as
provided in the Indenture may declare the principal amount (or, if the Debt
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) of all
Debt Securities of that series or such specified amount to be due an payable
immediately. However, at any time after a declaration of acceleration with
respect to Debt Securities of any series has been made, but before a judgment or
decree based on such acceleration has been obtained, the Holders of a majority
in principal amount of the Outstanding Debt Securities of that series may, under
certain circumstances, rescind and annul such acceleration. (Section 502) For
information as to waiver of defaults, see "Modification and Waiver" below.
 
The Indenture provides that, subject to the duty of the Trustee during an Event
of Default to act with the required standard of care, the Trustee will be under
no obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the Holders, unless such Holders shall have
offered to the Trustee reasonable security or indemnity. (Sections 601 and 603)
Subject to certain provisions, including those requiring security or
indemnification of the Trustee, the Holders of a majority in principal amount of
the Outstanding Debt Securities of any series will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Debt Securities of that series. (Section 512)
 
No holder of a Debt Security of any series will have any right to initiate any
proceeding with respect to the Indenture, or for the appointment of a receiver
or a trustee, or for any other remedy thereunder, unless (i) such Holder has
previously given to the Trustee written notice of a continuing Event of Default
with respect to the Debt Securities of that series, (ii) the Holders of at least
25% in aggregate principal amount of the Outstanding Debt Securities of that
series have made written request, and such Holder or Holders have offered
reasonable indemnity to the Trustee, to institute such proceeding as trustee and
(iii) the Trustee has failed to institute such proceeding, and has not received
from the Holders of a majority in aggregate principal amount of the Outstanding
Debt Securities of that series a direction inconsistent with such request,
within 60 days after such notice, request and offer. (Section 507) However, such
limitations do not apply to a suit instituted
 
                                        7
<PAGE>   12
 
by a Holder of a Security for the enforcement of payment of the principal of, or
premium, if any, or interest on such Security on or after the applicable due
date specified in such Debt Security. (Section 508)
 
The Company will be required to furnish to the Trustee annually a statement as
to the performance by the Company of its obligations under the Indenture and as
to any default in such performance. (Section 1004) The Indenture provides that
the Trustee may withhold notice to the Holders of the Debt Securities of any
series of the default (except in the case of a default in the payment of the
principal of, premium, if any, or interest on any Debt Securities of such series
or in the payment of any sinking fund installment with respect to Debt
Securities of such series) if the Trustee considers it in the interest of the
Holders of the Debt Securities to do so. (Section 602)
 
MODIFICATION AND WAIVER
 
Modifications and amendments of the Indenture may be made by the Company and the
Trustee with the consent of the Holders of not less than a majority in principal
amount of the Outstanding Debt Securities of each series affected thereby;
provided, however, that no such modification or amendment may, without the
consent of the Holder of each Outstanding Debt Security affected thereby: (a)
change the Stated Maturity of the principal of, or any installment of principal
of, or interest on, any Debt Security; (b) (unless otherwise provided in the
applicable Prospectus Supplement) reduce the principal amount of, the rate of
interest on, or the premium, if any, payable upon the redemption of, any Debt
Security; (c) reduce the amount of principal or an Original Issue Discount
Security payable upon acceleration of the Maturity thereof; (d) change the place
or currency of payment of principal of, premium, if any, or interest on any Debt
Security; (e) impair the right to institute suit for the enforcement of any
payment on or with respect to any Debt Security; or (f) reduce the percentage in
principal amount of Outstanding Debt Securities of any series, the consent of
the Holders of which is required for modification or amendment of the Indenture
or for waiver of compliance with certain provisions of the Indenture or for
waiver of certain defaults. (Section 902)
 
The Holders of not less than a majority in principal amount of the Outstanding
Debt Securities of any series may on behalf of the Holders of all Debt
Securities of that series waive, insofar as that series is concerned, compliance
by the Company with certain covenants of the Indenture. (Section 1006) The
Holders of not less than a majority in principal amount of the Outstanding Debt
Securities of any series may, on behalf of the Holders of all Debt Securities of
that series, waive any past default under the Indenture with respect to that
series, except a default in the payment of the principal of, premium, if any, or
interest on, any Debt Security of that series or in respect of a provision which
under the Indenture cannot be modified or amended without the consent of the
Holder of each Outstanding Debt Security of that series affected. (Section 513)
 
Without the consent of any Holder of Outstanding Debt Securities, the Company
and the Trustee may amend the Indenture to cure any ambiguity, omission, defect
or inconsistency, to provide for the assumption by a successor corporation,
partnership, trust or limited liability company of the obligations of the
Company under the Indenture, to provide for uncertificated Debt Securities in
addition to or in place of certificated Debt Securities (provided that the
uncertificated Debt Securities are issued in registered form for purposes of
Section 163(f) of the Internal Revenue Code of 1986, as amended (the "Code"), or
in a manner such that the uncertificated Debt Securities are described in
Section 163(f)(2)(B) of the Code), to secure the Debt Securities, to add to the
covenants
 
                                        8
<PAGE>   13
 
of the Company for the benefit of the holders or to surrender any right or power
conferred upon the Company, to make any change that does not adversely affect
the rights of any Holder or to comply with any requirement of the Commission in
connection with the qualification of the Indenture under the Trust Indenture Act
of 1939, as amended (the "Indenture Act").
 
Except in certain limited circumstances, the Company will be entitled to set any
day as a record date for the purpose of determining the Holders of Outstanding
Debt Securities of any series entitled to give or take any direction, notice,
consent, waiver or other action under the Indenture, in the manner and subject
to the limitations provided in the Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
The Company, without the consent of any Holders of Outstanding Debt Securities,
may consolidate with or merge into, or transfer or lease its assets
substantially as an entirety to, any Person, and any other Person may
consolidate with or merge into, or transfer or lease its assets substantially as
an entirety to, the Company, provided (a) that the Person (if other than the
Company) formed by such consolidation or into which the Company is merged or
which acquires or leases the assets of the Company substantially as an entirety
is a Person organized and existing under the laws of any United States
jurisdiction and assumes the Company's obligations on the Debt Securities and
under the Indenture, (b) that after giving effect to such transaction no Event
of Default, and no event which, after notice or lapse of time or both, would
become an Event of Default, shall have happened and be continuing, and (c) that
certain other conditions are met. (Article Eight)
 
DEFEASANCE
 
Unless otherwise indicated in the applicable Prospectus Supplement with respect
to the Debt Securities of a series, the Company, at its option, (i) will be
discharged from any and all obligations in respect of the Debt Securities of
such series (except for certain obligations to register the transfer or exchange
of Debt Securities of such series, to replace stolen, lost or mutilated Debt
Securities of such series, and to maintain paying agents and hold moneys for
payment in trust) or (ii) need not comply with any covenants that are specified
in a Prospectus Supplement, and the occurrence of an event described under
clause (c) with respect to any defeased covenant and clause (d) of the "Events
of Default" shall no longer be an Event of Default if, in each case, the Company
deposits with the Trustee, in trust, money or U.S. Government Obligations that
through the payment of interest thereon and principal thereof in accordance with
their terms will provide money in an amount sufficient to pay all the principal
of (and premium, if any) and any interest on the Debt Securities of such series
on the dates such payments are due (which may include one or more redemption
dates designated by the Company) in accordance with the terms of such Debt
Securities. Such a trust may only be established if, among other things, (a) no
Event of Default or event which with the giving of notice or lapse of time, or
both, would become an Event of Default under the Indenture shall have occurred
and be continuing on the date of such deposit, (b) in the event of a defeasance
of the type described in clause (i) above, no Event of Default described under
clause (e) of "Events of Default" above or event which with the giving of notice
or lapse of time, or both, would become an Event of Default described under such
clause (e) shall have occurred and be continuing at any time during the period
ending on the 91st day following such date of deposit, and (c) the Company shall
have delivered an Opinion of Counsel to the effect that the Holders of the Debt
Securities will not recognize income, gain or loss
 
                                        9
<PAGE>   14
 
for federal income tax purposes as a result of such deposit or defeasance and
will be subject to federal income tax in the same manner as if such defeasance
had not occurred.
 
In the event the Company omits to comply with its remaining obligations under
the Indenture after a defeasance of the Indenture with respect to the Debt
Securities of any series as described under clause (ii) above and the Debt
Securities of such series are declared due and payable because of the occurrence
of any undefeased Event of Default, the amount of money and U.S. Government
Obligations on deposit with the Trustee may be insufficient to pay amounts due
on the Debt Securities of such series at the time of the acceleration resulting
from such Event of Default. However, the Company will remain liable in respect
of such payments. (Article Thirteen)
 
GOVERNING LAW
 
The Indenture and the Debt Securities will be governed by, and construed in
accordance with, the laws of the State of New York. (Section 112)
 
REGARDING THE TRUSTEE
 
The Trustee and certain of its affiliates are the trustees under a number of
other indentures qualified under the Indenture Act, in respect of which the
Company is the obligor with respect to certain unsecured debt securities and are
the trustees under a number of indentures qualified under the Indenture Act in
respect of which the Company is the lessee of the equipment that constitutes the
collateral for the debt obligations issued pursuant to such indentures.
Affiliates of the Trustee are also the trustees under one or more indentures
with the Company that have not been qualified under the Indenture Act. Upon the
occurrence of an Event of Default, or any event of default under such other
indenture, the Trustee may be deemed to have a conflicting interest with respect
to the Securities for purposes of the Indenture Act and, accordingly, may be
required to resign as Trustee under the Indenture.
 
The Indenture contains certain limitations on the right of the Trustee, should
it become a creditor of the Company, to obtain payment of claims in certain
cases, or to realize for its own account on certain property received in respect
of any such claim as security or otherwise. (Section 613) The Trustee will be
permitted to engage in certain other transactions; however, if it acquires any
conflicting interest it must eliminate such conflict or resign. (Section 608)
 
                              SELLING STOCKHOLDERS
 
Some of the shares of Common Stock being offered pursuant to this Prospectus may
be offered by certain Selling Stockholders, including Michael A. Chowdry, the
Chairman, Chief Executive Officer and President of the Company, and certain
other officers of the Company. Identification of any such selling stockholder
will be made in the applicable Prospectus Supplement.
 
                              PLAN OF DISTRIBUTION
 
The Company (and with respect to shares of Common Stock, the selling
stockholders) may sell the Securities to or through underwriters and also may
sell Debt Securities directly to other purchasers or through agents.
 
                                       10
<PAGE>   15
 
The distribution of the Securities may be effected from time to time in one or
more transactions at a fixed price or prices, which may be changed, or at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices.
 
In connection with the sale of the Securities, underwriters or agents may
receive compensation from the Company or from purchasers of the Securities for
whom they may act as agents in the form of discounts, concessions or
commissions. Underwriters may sell the Securities to or through dealers, and
such dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agents. Underwriters, dealers and agents that participate
in the distribution of the Securities may be deemed to be underwriters, and any
discounts or commissions received by them from the Company and any profit on the
resale of the Securities by them may be deemed to be underwriting discounts and
commissions, under the Securities Act. Any such underwriter or agent will be
identified, and any such compensation received from the Company will be
described, in the applicable Prospectus Supplement.
 
Under agreements which may be entered into by the Company, underwriters and
agents who participate in the distribution of the Securities may be entitled to
indemnification by the Company against liabilities, including liabilities under
the Securities Act.
 
If so indicated in the applicable Prospectus Supplement, the Company will
authorize underwriters or other persons acting as the Company's agents to
solicit offers by certain institutions to purchase the Securities from the
Company pursuant to contracts providing for payment and delivery on a future
date. Institutions with which such contracts may be made include commercial and
savings banks, insurance companies, pension funds, investment companies,
educational and charitable institutions and others, but in all cases such
institutions must be approved by the Company. The obligations of any purchaser
under any such contract will be subject to the condition that the purchase of
the Securities being offered is not at the time of delivery prohibited under the
laws of the jurisdiction to which such purchaser is subject. The underwriters
and such other agents will not have any responsibility in respect of the
validity or performance of such contracts.
 
Unless otherwise indicated in the applicable Prospectus Supplement, Atlas does
not intend to apply for the listing of any Debt Securities on a national
securities exchange. If any Securities are sold to or through underwriters,
dealers or agents, the underwriters, dealers or agents may make a market in such
Securities, as permitted by applicable laws and regulations. No underwriter,
dealer or agent would be obligated, however, to make a market in such
Securities, and any such market-making could be discontinued at any time at the
sole discretion of the underwriter, dealer or agent. Accordingly, no assurance
can be given as to the liquidity of, or trading markets for, such Securities.
 
Certain of the underwritings or agents and their associates may be customers of,
engage in transactions with, and perform services for, the Company in the
ordinary course of business.
 
                           VALIDITY OF THE SECURITIES
 
Unless otherwise indicated in the applicable Prospectus Supplement, the validity
of the Securities offered hereby will be passed upon for the Company by Cahill
Gordon & Reindel (a partnership including a professional corporation), New York,
New York.

                       GENERAL OUTLINE OF TRUST STRUCTURE
 
A separate Trust will be formed for each series of Certificates to be offered
pursuant to a Pass Through Trust Agreement (the "Basic Agreement") and one or
more supplements thereto (each, a "Trust Supplement") between Atlas and the
trustee named therein (the "Trustee"), as trustee under each Trust. Concurrently
with the execution and delivery of each Trust Supplement, the Trustee, on behalf
of the Trust formed thereby, will enter into one or more purchase or refunding
agreements (each such agreement being herein referred to as a "Note Purchase
Agreement") pursuant to which it will agree to purchase one or more equipment
notes ("Equipment Notes") relating to one or more of the Aircraft described in
the applicable Prospectus Supplement. Pursuant to the applicable Note Purchase
Agreement or Note Purchase Agreements, the Trustee, on behalf of each Trust,
will purchase Equipment Notes of one or more series such that the Equipment
Notes that constitute the property of such Trust will have identical interest
rates (in each case equal to the rate applicable to the Certificates issued by
such Trust) and identical priority of payment relative to each of the other
Equipment Notes issued under the Related
 
                                        2
<PAGE>   21
 
Indentures (as defined below). The maturity dates of the Equipment Notes
acquired by each Trust will occur on or before the final distribution date
applicable to the Certificates that will be issued by such Trust. The Trustee
will distribute the amount of payments of principal, premium, if any, and
interest received by it as holder of the Equipment Notes to the registered
holders of Certificates of the Trust (the "Certificateholders") in which such
Equipment Notes are held, subject to the effect of any cross-subordination
provisions described in the Prospectus Supplement for a series of Certificates.
To the extent that the proceeds of any offering of Certificates are not used to
purchase Equipment Notes on the date of issuance of such Certificates, such
proceeds will be held for the benefit of the holders of such Certificates. If
any such proceeds are not subsequently utilized to purchase Equipment Notes by
the relevant date specified in the applicable Prospectus Supplement, such
proceeds will be returned to the holders of such Certificates. See "Description
of the Certificates" and "Description of the Equipment Notes".
 
                                USE OF PROCEEDS
 
Except as otherwise provided in the applicable Prospectus Supplement for a
specific offering of Certificates, the Certificates will be issued in order to
(a) finance or refinance the debt portion and, in certain cases, refinance some
of the equity portion of one or more separate leveraged Lease transactions
entered into by Atlas, as lessee, with respect to the Leased Aircraft, as
described in the applicable Prospectus Supplement, or (b) finance or refinance
the aggregate purchase price in respect of the Owned Aircraft as described in
the applicable Prospectus Supplement. Except as otherwise provided in the
applicable Prospectus Supplement for a specific offering of Certificates, the
proceeds from the sale of the Certificates will be used by the Trustee on behalf
of the applicable Trust or Trusts to purchase either (a) Leased Aircraft Notes
issued by the respective Owner Trustee or Owner Trustees to finance or refinance
(as specified in the applicable Prospectus Supplement) the related Leased
Aircraft, or (b) Owned Aircraft Notes issued by Atlas to finance or refinance
(as specified in the applicable Prospectus Supplement) the related Owned
Aircraft. To the extent that the proceeds of any offering of Certificates are
not used to purchase Equipment Notes on the date of issuance of such
Certificates, such proceeds will be held for the benefit of the holders of such
Certificates. If any such proceeds are not subsequently utilized to purchase
Equipment Notes by the relevant date specified in the applicable Prospectus
Supplement, such proceeds will be returned to the holders of such Certificates.
See "Description of Certificates -- Delayed Purchase of Equipment Notes".
 
The Leased Aircraft Notes will be issued under separate trust indentures (the
"Leased Aircraft Indentures") between a bank, trust company or other institution
specified in the related Prospectus Supplement, as trustee thereunder (in such
capacity, herein referred to as the "Loan Trustee"), and an institution
specified in the related Prospectus Supplement acting, not in its individual
capacity, but solely as owner trustee (an "Owner Trustee") of a separate trust
for the benefit of one or more institutional investors (each, an "Owner
Participant"). With respect to each Leased Aircraft, the related Owner
Participant will have provided or will provide from sources other than the
Leased Aircraft Notes a portion of the equipment cost of the related Leased
Aircraft. No Owner Participant, however, will be personally liable for any
amount payable under the related Leased Aircraft Indenture or the Leased
Aircraft Notes issued thereunder. Each Leased Aircraft will have been or will be
leased by the related Owner Trustee to Atlas pursuant to a separate lease
agreement (each such lease agreement, a "Lease"). The Owned Aircraft Notes will
be issued under
 
                                        3
<PAGE>   22
 
separate trust indentures (the "Owned Aircraft Indentures" and, together with
any Leased Aircraft Indentures, the "Indentures") between the applicable Loan
Trustee and Atlas.
 
                                  RISK FACTORS
 
In addition to the information set forth elsewhere in this Prospectus and the
applicable Prospectus Supplement, prospective purchasers of the Certificates
offered hereby should consider carefully the factors set forth below in
connection with an investment in Certificates as well as the risk factors
incorporated by reference in this Prospectus.
 
APPRAISALS AND REALIZABLE VALUE OF AIRCRAFT
 
The Prospectus Supplement will contain the appraised value of each Aircraft
based upon the lesser of the average and the median value of such Aircraft as
appraised by independent appraisers who will be named in the applicable
Prospectus Supplement (the "Appraisals") and whose report will be contained
therein. The Appraisals will be based on various assumptions and methodologies,
which vary among the Appraisals.
 
Appraisals based on different assumptions or methodologies may result in
valuations that are significantly different from those contained in the
Appraisals. An appraisal is only an estimate of value and should not be relied
upon as a measure of realizable value. The proceeds realized upon the sale of
any Aircraft may be less than the appraised value thereof. In addition, the
value of the Aircraft in the event of the exercise of remedies under the related
Indenture will depend on market and economic conditions at the time, the
availability of buyers, the condition of the Aircraft, whether the Aircraft are
sold separately or as a block and other factors. Accordingly, there can be no
assurance that the proceeds realized upon any such exercise with respect to the
Certificates and the Aircraft pursuant to the related Indenture will be as
appraised or sufficient to satisfy in full payments due on the Certificates
issued thereunder.
 
The Certificates are not cross-collateralized and, consequently, liquidation
proceeds from the sale of an Aircraft in excess of the principal amount of the
Certificates related to such Aircraft will not be available to cover losses, if
any, on any other Certificates.
 
PRIORITY OF DISTRIBUTIONS; SUBORDINATION
 
The Intercreditor Agreement may provide for the subordination of some series of
Certificates to other series, which may result in the holders of the
subordinated Certificates receiving less than the full amount due to them after
the occurrence of a payment default under any Equipment Note.
 
LACK OF CROSS-COLLATERALIZATION AND CROSS-DEFAULT PROVISIONS
 
There will be no cross-collateralization provisions in the Indentures and
consequently the Certificates issued in respect of one Aircraft will be secured
only by that Aircraft and will not be secured by any other Aircraft or the
Leases related to such other Aircraft. There will be no cross-default provisions
in the Indentures and consequently events resulting in an Indenture Event of
Default under any particular Indenture may not result in an Indenture Event of
Default occurring under any other Indenture.
 
RATINGS OF THE CERTIFICATES
 
It is expected that the Certificates will be assigned a rating by one or more
Rating Agencies. Such rating or ratings will be set forth in the Prospectus
Supplement applicable
 
                                        4
<PAGE>   23
 
to the Certificates being sold. A rating is not a recommendation to purchase,
hold or sell Certificates, inasmuch as such rating does not address market price
or suitability for a particular investor. There is no assurance that a rating
will remain for any given period of time or that a rating will not be lowered or
withdrawn entirely by a Rating Agency if in its judgment circumstances in the
future (including the downgrading of the Company) so warrant. The rating of the
Certificates will be based primarily on the default risk of the Certificates and
the collateral value provided by the Aircraft. The ratings are expected to
address the likelihood of timely payment of interest (at the non-default rate)
when due on the Certificates and the ultimate payment of principal of the
Certificates on the final expected distribution date. Such ratings are not
expected to address the possibility of a Lease Event of Default or Indenture
Event of Default or other circumstances (such as an Event of Loss) which may
result in the payment of the outstanding principal amount of the Certificates
prior to such final expected distribution date.
 
Unless specified in the applicable Prospectus Supplement, the reduction,
suspension or withdrawal of the ratings of the Certificates will not, in and of
itself, constitute an Indenture Event of Default.
 
HIGHLY LEVERAGED TRANSACTION
 
The Indentures contain no debt covenants or provisions that would afford the
Holders protection in the event of a highly leveraged transaction involving the
Company.
 
ABSENCE OF A PUBLIC MARKET FOR THE CERTIFICATES
 
Prior to their issuance, there will have been no public market for the
Certificates of any Series and there can be no assurance that one will develop.
Unless otherwise indicated in the applicable Prospectus Supplement, the Company
does not intend to apply for the listing of any Certificates on a national
securities exchange. There can be no assurance as to the liquidity of the public
market for the Certificates or that any active public market for the
Certificates will develop or continue. If an active public market does not
develop or continue, the market price and liquidity of the Certificates may be
adversely affected.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
The ratio of earnings to fixed charges represents the number of times that fixed
charges were covered by earnings. For purposes of computing the ratio of
earnings to fixed charges, "earnings" consists of income (loss) prior to income
tax benefit (expense), as adjusted to exclude the "Write-off of capital
investment and other" in the second quarter of 1997, and fixed charges
(excluding capitalized interest for the period). "Fixed charges" consist of
interest expense (including amounts capitalized), amortization of debt issuance
costs and one-third of rental payments on operating leases (such one-third
portion having been deemed by us to represent the interest portion of such
payments). The table below
 
                                        5
<PAGE>   24
 
presents the ratio of earnings to fixed charges for the years ended December 31,
1993, 1994, 1995, 1996 and 1997 and the nine months ended September 30, 1997 and
1998.

                        DESCRIPTION OF THE CERTIFICATES
 
In connection with each offering of Certificates, one or more separate Trusts
will be formed and one or more series of Certificates will be issued pursuant to
the Basic Agreement and one or more separate Trust Supplements to be entered
into between Atlas and the Trustee. The statements made under this caption are
summaries and reference is made to the detailed provisions of the Basic
Agreement, the form of which has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part. The summaries relate to the Basic
Agreement and each of the Trust Supplements, the Trusts to be formed thereby and
the Certificates to be issued by each Trust except to the extent, if any,
described in the applicable Prospectus Supplement. The Prospectus Supplement
that accompanies this Prospectus contains a glossary of the material terms used
with respect to the specific series of Certificates being offered thereby. The
Trust Supplement relating to each series of Certificates and the forms of the
related Note Purchase Agreement, Indenture, Lease, trust agreement,
Participation Agreement, intercreditor agreement and liquidity facility
arrangement, as applicable, will be filed as exhibits to a post-effective
amendment to the Registration Statement of which this Prospectus is a part, a
Current Report on Form 8-K, a Quarterly Report on Form 10-Q or an Annual Report
on Form 10-K, as applicable, filed by Atlas with the Commission.
 
The Certificates offered pursuant to this Prospectus will be limited to
$650,000,000 aggregate public offering price.
 
To the extent that any provision in any Prospectus Supplement is inconsistent
with any provision in this summary, the provision of such Prospectus Supplement
will control.
 
GENERAL
 
Each Certificate will represent a fractional undivided interest in the Trust
created by the Trust Supplement pursuant to which such Certificate was issued
and all payments and distributions shall be made only from the related Trust
Property (as defined below). The property of each Trust (the "Trust Property")
will include (i) the Equipment Notes held in such Trust and all monies at any
time paid thereon and all monies due and to become due thereunder, subject to
the effect of any cross-subordination provisions described in the Prospectus
Supplement for a series of Certificates, (ii) funds from time to time deposited
with the Trustee in accounts relating to such Trust and (iii) if so specified in
the Prospectus Supplement related to a series of Certificates, rights under
intercreditor agreements relating to cross-subordination arrangements and monies
receivable under a liquidity facility. Each Certificate will represent a pro
rata share of the outstanding principal amount of the Equipment Notes held in
the related Trust and, unless otherwise
 
                                        6
<PAGE>   25
 
specified in the applicable Prospectus Supplement, will be issued in minimum
denominations of $1,000 or any integral multiple thereof except that one
Certificate of each series may be issued in a different denomination. The
Certificates do not represent an interest in or obligation of Atlas, the
Trustee, any of the Loan Trustees or Owner Trustees in their individual
capacities, any Owner Participant, or any affiliate of any thereof. Each
Certificateholder by its acceptance of a Certificate agrees to look solely to
the income and proceeds from the Trust Property as provided in the Basic
Agreement and the applicable Trust Supplement.
 
The Equipment Notes issued under an Indenture may be held in more than one Trust
and one Trust may hold Equipment Notes issued under more than one Indenture
(each Indenture the Equipment Notes of which are held in a Trust, a "Related
Indenture"). Unless otherwise provided in a Prospectus Supplement, only
Equipment Notes having the same priority of payment (the Equipment Notes of any
such priority, a "Class") may be held in the same Trust.
 
Interest will be passed through to Certificateholders of each Trust at the rate
per annum payable on the Equipment Notes held in such Trust, as set forth for
such Trust on the cover page of the applicable Prospectus Supplement, subject to
the effect of any cross-subordination provisions described in the Prospectus
Supplement for a series of Certificates.
 
Reference is made to the Prospectus Supplement that accompanies this Prospectus
for a description of the specific series of Certificates being offered thereby,
including (1) the specific designation and title of such Certificates; (2) the
Regular Distribution Dates (as defined below) and Special Distribution Dates (as

considerations, specific terms and other information with respect to such
Certificates and such foreign currency or currency units will be set forth in
the applicable Prospectus Supplement.
 
                            BOOK-ENTRY REGISTRATION
 
GENERAL
 
If specified in the applicable Prospectus Supplement, the Certificates will be
subject to the provisions described below and under the caption "-- Definitive
Certificates". Upon issuance, each series of Certificates will be represented by
one or more fully registered global certificates. Unless otherwise provided in a
Prospectus Supplement, each global certificate will be deposited with, or on
behalf of, The Depository Trust Company ("DTC") and registered in the name of
Cede & Co. ("Cede"), the nominee of DTC. No person acquiring an interest in such
Certificates ("Certificate Owner") will be entitled to receive a certificate
representing such person's interest in such Certificates, except as set forth
below under "-- Definitive Certificates". Unless and until Definitive
Certificates are issued under the limited circumstances described herein, all
references to actions by Certificateholders shall refer to actions taken by DTC
upon instructions from DTC Participants (as defined below), and all references
herein to distributions, notices, reports and statements to Certificateholders
shall refer, as the case may be, to distributions, notices, reports and
statements to DTC or Cede, as the registered holder of such Certificates, or to
DTC Participants for distribution to Certificate Owners in accordance with DTC
procedures.
 
DTC is a limited purpose trust company organized under the laws of the State of
New York, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code and a "clearing
agency" registered pursuant to section 17A of the Exchange Act. DTC was created
to hold securities for its participants ("DTC Participants") and to facilitate
the clearance and settlement of securities transactions between DTC Participants
through electronic book-entries, thereby eliminating the need for physical
transfer of certificates. DTC Participants include securities brokers and
dealers, banks, trust companies and clearing corporations. Indirect access to
the DTC system also is available to others such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with DTC
Participant either directly or indirectly ("Indirect Participants").
 
Certificate Owners that are not DTC Participants or Indirect Participants but
desire to purchase, sell or otherwise transfer ownership of, or other interests
in, the Certificates may do so only through DTC Participants and Indirect
Participants. In addition, Certificate Owners will receive all distributions of
principal and interest from the Trustee through DTC Participants or Indirect
Participants, as the case may be. Under a book-entry format, Certificate Owners
may experience some delay in their receipt of payments, because such payments
will be forwarded by the Trustee to Cede, as nominee for DTC. DTC will forward
such payments in same-day funds to DTC Participants who are credited with
ownership of the Certificates in amounts proportionate to the principal amount
of each such DTC Participant's respective holdings of beneficial interests in
the Certificates. DTC
 
                                        8
<PAGE>   27
 
Participants will thereafter forward payments to Indirect Participants or
Certificate Owners, as the case may be, in accordance with customary industry
practices. The forwarding of such distributions to the Certificate Owners will
be the responsibility of such DTC Participants. Unless and until the Definitive
Certificates are issued under the limited circumstances described herein, the
only "Certificateholder" will be Cede, as nominee of DTC. Certificate Owners
will not be recognized by the Trustee as Certificateholders, as such term is
used in the Basic Agreement, and Certificate Owners will be permitted to
exercise the rights of Certificateholders only indirectly through DTC and DTC
Participants.
 
Under the rules, regulations and procedures creating and affecting DTC and its
operations (the "Rules"), DTC is required to make book-entry transfers of the
Certificates among DTC Participants on whose behalf it acts with respect to the
Certificates and to receive and transmit distributions of principal, premium, if
any, and interest with respect to the Certificates. DTC Participants and
Indirect Participants with which Certificate Owners have accounts with respect
to the Certificates similarly are required to make book-entry transfers and
receive and transmit such payments on behalf of their respective customers.
Accordingly, although Certificate owners will not possess the Certificates, the
Rules provide a mechanism by which Certificate Owners will receive payments and
will be able to transfer their interests.
 
Because DTC can only act on behalf of DTC Participants, who in turn act on
behalf of Indirect Participants, the ability of a Certificate Owner to pledge
the Certificates to persons or entities that do not participate in the DTC
system, or to otherwise act with respect to such Certificates, may be limited
due to the lack of a physical certificate for such Certificates.
 
DTC will take any action permitted to be taken by a Certificateholder under the
Basic Agreement only at the direction of one or more DTC Participants to whose
accounts with DTC the Certificates are credited. Additionally, in the event any
action requires approval by Certificateholders of a certain percentage of
beneficial interest in each Trust, DTC will take such action only at the
direction of and on behalf of DTC Participants whose holdings include undivided
interests that satisfy any such percentage. DTC may take conflicting actions
with respect to other undivided interests to the extent that such actions are
taken on behalf of DTC Participants whose holdings include such undivided
interests.
 
Neither Atlas nor the Trustee will have any liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the Certificates held by Cede, as nominee for DTC, or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
The applicable Prospectus Supplement will specify any additional book-entry
registration procedures applicable to Certificates denominated in a currency
other than United States dollars.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
So long as the Certificates are registered in the name of DTC or its nominee,
all payments made by Atlas to the Loan Trustee under any Lease or any Owned
Aircraft Indenture will be in immediately available funds. Such payments,
including the final distribution of principal with respect to the Certificates
of any Trust, will be passed through to DTC in immediately available funds.
 
                                        9
<PAGE>   28
 
Any Certificates registered in the name of DTC or its nominee, will trade in
DTC's Same-Day Funds Settlement System until maturity, and secondary market
trading activity in the Certificates will therefrom be required by DTC to settle
in immediately available funds. No assurance can be given as to the effect, if
any, of settlement in same-day funds on trading activity in the Certificates.
 
DEFINITIVE CERTIFICATES
 
Certificates will be issued in certificated form ("Definitive Certificates") to
Certificate Owners or their nominees, rather than to DTC or its nominee, only if
(i) Atlas advises the Trustee in writing that DTC is no longer willing or able
to discharge properly its responsibilities as depository with respect to such
Certificates and Atlas is unable to locate a qualified successor, (ii) Atlas, at
its option, elects to terminate the book-entry system through DTC or (iii) after
the occurrence of certain events of default or other events specified in the
related Prospectus Supplement, Certificate Owners with fractional undivided
interests aggregating not less than a majority in interest in such Trust advise
the Trustee, Atlas and DTC through DTC Participants in writing that the
continuation of a book-entry system through DTC (or a successor thereto) is no
longer in the Certificate Owners' best interest. Upon the occurrence of any
event described in the immediately preceding sentence, the Trustee will be
required to notify all Certificate Owners through DTC Participants of the
availability of Definitive Certificates. Upon surrender by DTC of the
certificates representing the Certificates and receipt of instructions for
re-registration, the Trustee will reissue the Certificates as Definitive
Certificates to Certificate Owners.
 
Distributions of principal, premium, if any, and interest with respect to
Certificates will thereafter be made by the Trustee directly in accordance with
the procedures set forth in the Basic Agreement and the applicable Trust
Supplements, to holders in whose names the Definitive Certificates were
registered at the close of business on the applicable record date. Such
distributions will be made by check mailed to the address of such holder as it
appears on the register maintained by the Trustee. The final payment on any
Certificate, however, will be made only upon presentation and surrender of such
Certificate at the office or agency specified in the notice of final
distribution to Certificateholders.
 
Definitive Certificates will be freely transferable and exchangeable at the
office of the Trustee upon compliance with the requirements set forth in the
Basic Agreement and the applicable Trust Supplements. No service charge will be
imposed for any registration of transfer or exchange, but payment of a sum
sufficient to cover any tax or other governmental charge shall be required.
 
PAYMENTS AND DISTRIBUTIONS
 
Subject to the effect of any cross-subordination provisions set forth in the
Prospectus Supplement for a series of Certificates, payments of principal,
premium, if any, and interest with respect to the Equipment Notes held in each
Trust will be distributed by the Trustee, upon receipt, to Certificateholders of
such Trust on the dates specified in the applicable Prospectus Supplement,
except in certain cases when some or all of such Equipment Notes are in default
as described in the applicable Prospectus Supplement. Payments of principal of,
and interest on, the unpaid principal amount of the Equipment Notes held in each
Trust will be scheduled to be received by the Trustee on the dates specified in
the applicable Prospectus Supplement (such scheduled payments of interest and
principal on the Equipment Notes to the Trustee are herein referred to as
"Scheduled Payments", and the dates specified in the applicable Prospectus
Supplement for
 
                                       10
<PAGE>   29
 
distribution of Scheduled Payments to the Trustee are herein referred to as
"Regular Distribution Dates"). See "Description of the Equipment
Notes -- General". Subject to the effect of any cross-subordination provisions
set forth in the Prospectus Supplement for a series of Certificates, each
Certificateholder of each Trust will be entitled to receive a pro rata share of
any distribution in respect of Scheduled Payments of principal and interest made
on the Equipment Notes held in the Trust.
 
Payments of principal, premium, if any, and interest received by the Trustee on
account of the early redemption or purchase, if any, of the Equipment Notes
relating to one or more Aircraft held in a Trust, and payments, other than
Scheduled Payments received on a Regular Distribution Date or within five days
thereafter ("Special Payments"), received by the Trustee relating to one or more
Aircraft will be distributed on the date determined as described in the
applicable Prospectus Supplement (a "Special Distribution Date") except that, if
specified in the applicable Prospectus Supplement, payments received by the
Trustee following default in respect of the Equipment Notes on a Regular
Distribution Date as a result of a drawing under any liquidity facility, as
described in the applicable Prospectus Supplement (each, a "Liquidity
Facility"), provided for the benefit of the specified Certificateholders shall
be distributed on such Regular Distribution Date to such Certificateholders. The
Trustee will mail notice to the Certificateholders of record of the applicable
Trust stating any anticipated Special Distribution Date.
 
POOL FACTORS
 
Unless otherwise described in the applicable Prospectus Supplement, the "Pool
Balance" for each Trust or for the Certificates issued by any Trust indicates,
as of any date, the original aggregate face amount of the Certificates of such
Trust less the aggregate amount of all payments made in respect of the
Certificates of such Trust other than payments made in respect of interest or
premium thereon or reimbursement of any costs and expenses in connection
therewith. The Pool Balance for each Trust as of any Regular Distribution Date
or Special Distribution Date shall be computed after giving effect to the
payment of principal, if any, on the Equipment Notes or other Trust Property
held in such Trust and the distribution thereof to be made on that date.
 
Unless otherwise described in the applicable Prospectus Supplement, the "Pool
Factor" for each Trust as of any Regular Distribution Date or Special
Distribution Date is the quotient (rounded to the seventh decimal place)
computed by dividing (i) the Pool Balance by (ii) the aggregate original face
amount of the Certificates of such Trust. The Pool Factor for each Trust as of
any Regular Distribution Date or Special Distribution Date shall be computed
after giving effect to the payment of principal, if any, on the Equipment Notes
or other Trust Property held in such Trust and distribution thereof to be made
on that date. The Pool Factor for each Trust will initially be 1.0000000;
thereafter, the Pool Factor for each Trust will decline as described herein to
reflect reductions in the Pool Balance of such Trust. The amount of a
Certificateholder's pro rata share of the Pool Balance of a Trust can be
determined by multiplying the original denomination of the holder's Certificate
of such Trust by the Pool Factor for such Trust as of the applicable Regular
Distribution Date or Special Distribution Date. The Pool Factor and the Pool
Balance for each Trust will be mailed to Certificateholders of such Trust on
each Regular Distribution Date and Special Distribution Date.
 
Unless there has been an early redemption, a purchase of an issue of Equipment
Notes by the related Owner Trustee after an Indenture Default (as defined
below), a default in the payment of principal in respect of one or more issues
of the Equipment Notes held in a
 
                                       11
<PAGE>   30
 
Trust or certain actions have been taken following a default thereon, as
described in the applicable Prospectus Supplement, the Pool Factor for the
Trusts will decline in proportion to the scheduled repayments of principal on
the Equipment Notes held in such Trust as described in the applicable Prospectus
Supplement. In the event of such redemption, purchase or payment default (if
such payment is not made within five days of the Regular Distribution Date), the
Pool Factor and the Pool Balance of each Trust so affected will be recomputed
after giving effect thereto and notice thereof will be mailed to the
Certificateholders of such Trust. Each Trust will have a separate Pool Factor.
 
REPORTS TO CERTIFICATEHOLDERS
 
On each Regular Distribution Date and Special Distribution Date, the Trustee
will include with each distribution of a Scheduled Payment or Special Payment to
Certificateholders of the related Trust a statement, giving effect to such
distribution to be made on such Regular Distribution Date or Special
Distribution Date, setting forth the following information (per $1,000 aggregate
principal amount of Certificate for such Trust, as to (i) and (ii) below):
 
      (i) the amount of such distribution allocable to principal and the amount
          allocable to premium, if any;
 
      (ii) the amount of such distribution allocable to interest; and
 
     (iii) the Pool Balance and the Pool Factor for such Trust.
 
So long as the Certificates are registered in the name of DTC or its nominee, on
the record date prior to each Regular Distribution Date and Special Distribution
Date, the Trustee will request from DTC a securities position listing setting
forth the names of all DTC Participants reflected on DTC's books as holding
interests in the Certificates on such record date. On each Regular Distribution
Date and Special Distribution Date, the applicable Trustee will mail to each
such DTC Participant the statement described above and will make available
additional copies as requested by such DTC Participant for forwarding to
Certificate Owners.
 
In addition, after the end of each calendar year, the Trustee will prepare for
each Certificateholder of each Trust at any time during the preceding calendar
year a report containing the sum of the amounts determined pursuant to clauses
(i) and (ii) above with respect to the Trust for such calendar year or, in the
event such person was a Certificateholder during only a portion of such calendar
year, for the applicable portion of such calendar year, and such other items as
are readily available to the Trustee and which a Certificateholder shall
reasonably request as necessary for the purpose of such Certificateholder's
preparation of its federal income tax returns. Such report and such other items
shall be prepared on the basis of information supplied to the Trustee by the DTC
Participants and shall be delivered by the Trustee to such DTC Participants to
be available for forwarding by such DTC Participants to Certificate Owners in
the manner described above.
 
At such time, if any, as the Certificates are issued in the form of Definitive
Certificates, the Trustee will prepare and deliver the information described
above to each Certificateholder of record of each Trust as the name and period
of ownership of such Certificateholder appears on the records of the registrar
of the Certificates.
 
                                       12
<PAGE>   31
 
VOTING OF EQUIPMENT NOTES
 
Subject to the effect of any cross-subordination provisions set forth in the
related Prospectus Supplement, the Trustee, as holder of the Equipment Notes
held in each Trust, has the right to vote and give consents and waivers with
respect to such Equipment Notes under the Related Indentures. The Basic
Agreement and related Trust Supplement set forth (i) the circumstances in which
the Trustee may direct any action or cast any vote as the holder of the
Equipment Notes held in the applicable Trust at its own discretion, (ii) the
circumstances in which the Trustee shall seek instructions from the
Certificateholders of such Trust and (iii) the percentage of Certificateholders
required to direct the Trustee to take any such action. If specified in the
related Prospectus Supplement, the right of a Trustee to vote and give consents
and waivers with respect to the Equipment Notes held in the related Trust may,
in the circumstances set forth in an intercreditor agreement to be executed by
such Trustee and specified in such Prospectus Supplement, be exercisable by
another person specified in such Prospectus Supplement.
 
EVENTS OF DEFAULT AND CERTAIN RIGHTS UPON AN EVENT OF DEFAULT
 
The Prospectus Supplement will specify the events of default under the Basic
Agreement (an "Event of Default") and the Related Indentures (an "Indenture
Default"). The Indenture Defaults in the case of Leased Aircraft Indentures will
include events of default under the related Leases (a "Lease Event of Default").
With respect to any Equipment Notes which are supported by a Liquidity Facility,
the Indenture Defaults or Events of Default may include events of default under
such Liquidity Facility. Unless otherwise provided in a Prospectus Supplement,
all of the Equipment Notes issued under the same Indenture will relate to a
specific Aircraft and there will be no cross-collateralization or cross-default
provisions in the Indentures; accordingly, events resulting in an Indenture
Default under any particular Indenture would not necessarily result in an
Indenture Default occurring under any other Indenture. If an Indenture Default
occurs in fewer than all of the Indentures, notwithstanding the treatment of
Equipment Notes issued under any Indenture under which an Indenture Default has
occurred, payments of principal and interest on the Equipment Notes issued
pursuant to Indentures with respect to which an Indenture Default has not
occurred will continue to be made as originally scheduled. As described below
under "-- Cross-Subordination Issues", a Prospectus Supplement may provide the
terms of any cross-subordination provisions among Certificateholders of separate
Trusts. If such provisions are so provided, payments made pursuant to a Related
Indenture under which an Indenture Default has not occurred may be distributed
first to the holders of the Certificates issued under the Trust which holds the
most senior Equipment Notes issued under all Related Indentures.
 
The ability of the applicable Owner Trustee or Owner Participant under a Leased
Aircraft Indenture to cure Indenture Defaults, including an Indenture Default
that results from the occurrence of a Lease Event of Default under the related
Lease, will be described in the Prospectus Supplement. Unless otherwise provided
in a Prospectus Supplement, with respect to any Certificates or Equipment Notes
entitled to the benefits of a Liquidity Facility, a drawing under any such
Liquidity Facility for the purpose of making a payment of interest as a result
of the failure by Atlas to have made a corresponding payment will not cure an
Indenture Default or any Lease Default related to such failure by Atlas.
 
The Prospectus Supplement related to a series of Certificates will describe the
circumstances under which the Trustee of the related Trust may vote some or all
of the Equipment Notes held in such Trust. Such Prospectus Supplement also will
set forth the
 
                                       13
<PAGE>   32
 
percentage of Certificateholders of such Trust entitled to direct the Trustee to
take any action with respect to such Equipment Notes. If the Equipment Notes
outstanding under an Indenture are held by more than one Trust, then the ability
of the Certificateholders issued with respect to any one Trust to cause the Loan
Trustee with respect to any Equipment Notes held in such Trust to accelerate the
Equipment Notes under the applicable Indenture or to direct the exercise of
remedies by the Loan Trustee under the applicable Indenture will depend, in
part, upon the proportion of the aggregate principal amount of the Equipment
Notes outstanding under such Indenture and held in such Trust to the aggregate
principal amount of all Equipment Notes outstanding under such Indenture. In
addition, if cross-subordination provisions are applicable to any series of
Certificates, then the ability of the Certificateholders of any one Trust
holding Equipment Notes issued under an Indenture to cause the Loan Trustee with
respect to any Equipment Notes held in such Trust to accelerate the Equipment
Notes under such Indenture or to direct the exercise of remedies by the Loan
Trustee under such Indenture will depend, in part, upon the Class of Equipment
Notes held in such Trust. If the Equipment Notes outstanding under an Indenture
are held by more than one Trust, then each Trust will hold Equipment Notes with
different terms from the Equipment Notes held in the other Trusts and therefore
the Certificateholders of each Trust may have divergent or conflicting interests
from those of the Certificateholders of the other Trusts holding Equipment Notes
issued under the same Indenture. In addition, so long as the same institution
acts as Trustee of each Trust, in the absence of instructions from the
Certificateholders of any such Trust, the Trustee for such Trust could for the
same reason be faced with a potential conflict of interest upon an Indenture
Default. In such event, the Trustee has indicated that it would resign as
Trustee of one or all such Trusts, and a successor trustee would be appointed in
accordance with the terms of the Basic Agreement.
 
The Prospectus Supplement for a series of Certificates will specify whether and
under what circumstances the Trustee may sell for cash to any person all or part
of the Equipment Notes held in the related Trust. Any proceeds received by the
Trustee upon any such sale shall be deposited in an account established by the
Trustee for the benefit of the Certificateholders of such Trust for the deposit
of such Special Payments (the "Special Payments Account") and shall be
distributed to the Certificateholders of such Trust on a Special Distribution
Date. The market for Equipment Notes in default may be very limited, and there
can be no assurance that they could be sold for a reasonable price. Furthermore,
so long as the same institution acts as Trustee of multiple Trusts, it may be
faced with a conflict in deciding from which Trust to sell Equipment Notes to
available buyers. If the Trustee sells any such Equipment Notes with respect to
which an Indenture Default exists for less than their outstanding principal
amount, the Certificateholders of such Trust will receive a smaller amount of
principal distributions than anticipated and will not have any claim for the
shortfall against Atlas, any Owner Trustee, Owner Participant or the Trustee.
Furthermore, unless otherwise specified in the applicable Prospectus Supplement,
neither the Trustee nor the Certificateholders of such Trust could take any
action with respect to any remaining Equipment Notes held in such Trust so long
as no Indenture Defaults exist with respect thereto.
 
Any amount, other than Scheduled Payments received on a Regular Distribution
Date or within five days thereafter, distributed to the Trustee of any Trust by
the Loan Trustee under any Indenture on account of the Equipment Notes held in
such Trust following an Indenture Default under such Indenture shall be
deposited in the Special Payments Account for such Trust and shall be
distributed to the Certificateholders of such Trust on a Special Distribution
Date. In addition, if a Prospectus Supplement provides that the
 
                                       14
<PAGE>   33
 
applicable Owner Trustee may, under circumstances specified therein, redeem or
purchase the outstanding Equipment Notes issued under the applicable Indenture,
the price paid by such Owner Trustee to the Trustee of any Trust for the
Equipment Notes issued under such Indenture and held in such Trust shall be
deposited in the Special Payments Account for such Trust and shall be
distributed to the Certificateholders of such Trust on a Special Distribution
Date.
 
Any funds representing payments received with respect to any Equipment Notes in
default held in a Trust, or the proceeds from the sale by the Trustee of any
such Equipment Notes, held by the Trustee in the Special Payments Account for
such Trust shall, to the extent practicable, be invested and reinvested by the
Trustee in Permitted Investments pending the distribution of such funds on a
Special Distribution Date. "Permitted Investments" will be specified in the
related Prospectus Supplement.
 
The Basic Agreement provides that the Trustee of each Trust shall, within 90
days after the occurrence of a default (as defined below) in respect of such
Trust, give to the Certificateholders of such Trust notice, transmitted by mail,
of all uncured or unwaived defaults with respect to such Trust known to it,
provided that, except in the case of default in the payment of principal,
premium, if any, or interest on any of the Equipment Notes held in such Trust,
the Trustee shall be protected in withholding such notice if it in good faith
determines that the withholding of such notice is in the interests of such
Certificateholders. The term "default" as used in this paragraph only means the
occurrence of an Indenture Default with respect to Equipment Notes held in a
Trust as described above, except that in determining whether any such Indenture
Default has occurred, any grace period or notice in connection therewith shall
be disregarded.
 
The Basic Agreement contains a provision entitling the Trustee of each Trust,
subject to the duty of the Trustee during a default to act with the required
standard of care, to be offered reasonable security or indemnity by the
Certificateholders of such Trust before proceeding to exercise any right or
power under the Basic Agreement at the request of such Certificateholders.
 
The Prospectus Supplement for a series of Certificates will specify the
percentage of Certificateholders entitled to waive, or to instruct the Trustee
to waive, any past Event of Default with respect to such Trust and its
consequences. The Prospectus Supplement for a series of Certificates also will
specify the percentage of Certificateholders (and whether of such Trust or of
any other Trust holding Equipment Notes issued under Related Indentures)
entitled to waive, or to instruct the Trustee or the Loan Trustee to waive, any
past Indenture Default under any Related Indenture and thereby annul any
direction given with respect thereto.
 
MERGER, CONSOLIDATION AND TRANSFER OF ASSETS
 
Atlas will be prohibited from consolidating with or merging into any other
corporation or transferring substantially all of its assets as an entirety to
any other corporation unless (i) the surviving, successor or transferee
corporation shall (a) be organized and validly existing under the laws of the
United States or any state thereof or the District of Columbia, (b) be a
"citizen of the United States" (as defined in Title 49 of the United States Code
relating to aviation (the "Transportation Code")) holding an air carrier
operating certificate issued by the Secretary of Transportation pursuant to
Chapter 447 of Title 49, United States Code, if, and so long as, such status is
a condition of entitlement to the benefits of Section 1110 of the Bankruptcy
Code, and (c) expressly assume all of the obligations of Atlas contained in the
Basic Agreement and any Trust
 
                                       15
<PAGE>   34
 
Supplement, the Note Purchase Agreements, any Owned Aircraft Indentures and,
with respect to the Leased Aircraft, the applicable Participation Agreements and
Leases, and any other operative documents; and (ii) Atlas shall have delivered a
certificate and an opinion or opinions of counsel indicating that such
transaction, in effect, complies with such conditions.
 
The Pass Through Trust Agreements, the Note Purchase Agreement, the Indentures,
the Participation Agreements and the Leases will not contain any covenants or
provisions which may afford the applicable Trustee or Certificateholders
protection in the event of a highly leveraged transaction, including
transactions effected by management or affiliates, which may or may not result
in a change in control of Atlas.
 
MODIFICATIONS OF THE BASIC AGREEMENT
 
The Basic Agreement contains provisions permitting Atlas and the Trustee of each
Trust to enter into a supplemental trust agreement, without the consent of the
holders of any of the Certificates of such Trust, including among other things
(i) to provide for the formation of such Trust and the issuance of a series of
Certificates, (ii) to evidence the succession of another corporation to Atlas
and the assumption by such corporation of Atlas' obligations under the Basic
Agreement and the applicable Trust Supplement, (iii) to add to the covenants of
Atlas for the benefit of holders of such Certificates, or to surrender any right
or power in the Basic Agreement conferred upon Atlas, (iv) to cure any ambiguity
or correct or supplement any defective or inconsistent provision of the Basic
Agreement or the applicable Trust Supplement or to make any other provisions
with respect to matters or questions arising thereunder, provided such action
shall not materially adversely affect the interests of the holders of such
Certificates, or to cure any ambiguity or correct any mistake or (without
limitation of the foregoing), to give effect or provide for replacement
liquidity facilities, if applicable to such Certificates, (v) to comply with any
requirement of the Commission, any applicable law, rules or regulations of any
exchange or quotation system, on which any Certificates may be listed or of any
regulatory body, (vi) to modify, eliminate or add to the provisions of the Basic
Agreement to the extent as shall be necessary to continue the qualification of
the Basic Agreement (including any supplemental agreement) under the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act") and to add to the
Basic Agreement such other provisions as may be expressly permitted by the Trust
Indenture Act, with certain exceptions, (vii) to provide for a successor Trustee
or to add to or change any provision of the Basic Agreement as shall be
necessary to facilitate the administration of the Trusts thereunder by more than
one Trustee and (viii) to make any other amendments or modifications to the
Basic Agreement, provided such amendments or modifications shall only apply to
Certificates issued thereafter;provided, in the case of clauses (i) through
(viii) above, that no such supplemental trust agreement shall adversely affect
the status of any Trust as a grantor trust for U.S. federal income tax purposes.
 
The Basic Agreement also contains provisions permitting Atlas and the Trustee of
each Trust, with the consent of the Certificateholders of such Trust evidencing
fractional undivided interests aggregating not less than a majority in interest
of such Trust (and with the consent of any related Owner Trustee), to execute
supplemental trust agreements adding any provisions to or changing or
eliminating any of the provisions of the Basic Agreement, to the extent relating
to such Trust, and the applicable Trust Supplement, or modifying the rights of
the Certificateholders, except that no such supplemental trust agreement may,
without the consent of each Certificateholder so affected thereby, (a) reduce in
any manner the amount of, or delay the timing of, any receipt by the
 
                                       16
<PAGE>   35
 
Trustee of payments on the Equipment Notes held in such Trust or distributions
in respect of any Certificate related to such Trust, or change the date or place
of any payment in respect of any Certificate, or make distributions payable in
coin or currency other than that provided for in such Certificates, or impair
the right of any Certificateholder of such Trust to institute suit for the
enforcement of any such payment when due, (b) permit the disposition of any
Equipment Note held in such Trust, except as provided in the Basic Agreement or
the applicable Trust Supplement, or otherwise deprive any Certificateholder of
the benefit of the ownership of the applicable Equipment Notes, (c) reduce the
percentage of the aggregate fractional undivided interests of the Trust provided
for in the Basic Agreement or the applicable Trust Supplement, the consent of
the holders of which is required for any such supplemental trust agreement or
for any waiver provided for in the Basic Agreement or such Trust Supplement, (d)
modify any of the provisions relating to the rights of the Certificateholders in
respect of the waiver of events of default or supplemental agreements, with
certain limited exceptions, (e) alter the priority of distributions specified in
any applicable intercreditor agreement in a manner materially adverse to the
interests of the Certificateholders of such Trust or (f) adversely affect the
status of any Trust as a grantor trust for U.S. federal income tax purposes.
 
MODIFICATION OF INDENTURE AND RELATED AGREEMENTS
 
The Prospectus Supplement will specify the Trustee's obligations in the event
that the Trustee, as the holder of any Equipment Notes held in a Trust, receives
a request for its consent to any amendment, modification or waiver under the
Indenture or other documents relating to such Equipment Notes (including any
Lease with respect to Leased Aircraft Notes) or any Liquidity Facility.
 
CROSS-SUBORDINATION ISSUES
 
The Equipment Notes issued under an Indenture may be held in more than one Trust
and one Trust may hold Equipment Notes issued under more than one Related
Indenture. Unless otherwise provided in a Prospectus Supplement, only Equipment
Notes of the same Class may be held in the same Trust. In such event, payments
made on account of a subordinate class of Certificates issued under a Prospectus
Supplement may, under circumstances described in such Prospectus Supplement, be
subordinated to the prior payment of all amounts owing to Certificateholders of
a Trust which holds senior Equipment Notes issued under any Related Indentures.
The Prospectus Supplement related to an issuance of Certificates will describe
any such "cross-subordination" provisions and any related terms, including the
percentage of Certificateholders under any Trust which are permitted to (i)
grant waivers of defaults under any Related Indenture, (ii) consent to the
amendment or modification of any Related Indenture or (iii) direct the exercise
of remedial actions under any Related Indenture. Payments made on account of
Certificates may also be subordinated to the rights of the provider of any
related Liquidity Facility, as described below.
 
TERMINATION OF THE TRUSTS
 
The obligations of Atlas and the Trustee with respect to a Trust will terminate
upon the distribution to Certificateholders of such Trust of all amounts
required to be distributed to them pursuant to the Basic Agreement and the
applicable Trust Supplement and the disposition of all property held in such
Trust. The Trustee will send to each Certificateholder of record of such Trust
notice of the termination of such Trust, the amount of the proposed final
payment and the proposed date for the distribution of such
 
                                       17
<PAGE>   36
 
final payment for such Trust. The final distribution to any Certificateholder of
such Trust will be made only upon surrender of such Certificateholder's
Certificates at the office or agency of the Trustee specified in such notice of
termination.
 
DELAYED PURCHASE OF EQUIPMENT NOTES
 
In the event that, on the issuance date of any Certificates, all of the proceeds
from the sale of such Certificates are not used to purchase the Equipment Notes
contemplated to be held in the related Trust, such Equipment Notes may be
purchased by the Trustee at any time on or prior to the date specified in the
applicable Prospectus Supplement. In such event, the proceeds from the sale of
such Certificates not used to purchase Equipment Notes will be held under an
arrangement described in the applicable Prospectus Supplement pending the
purchase of the Equipment Notes not so purchased. The arrangements with respect
to the payment of interest on funds so held will be described in the applicable
Prospectus Supplement. If any such proceeds are not subsequently utilized to
purchase Equipment Notes by the relevant date specified in the applicable
Prospectus Supplement, such proceeds will be returned to the holders of such
Certificates.
 
LIQUIDITY FACILITY
 
The related Prospectus Supplement may provide that distributions made by the
Trustee with respect to the related Certificates will be supported by a
Liquidity Facility issued by an institution identified in the related Prospectus
Supplement. The provider of such Liquidity Facility may have a claim senior to
the Certificateholders' as specified in the related Prospectus Supplement.
 
THE TRUSTEE
 
Unless otherwise provided in the Prospectus Supplement for any series of
Certificates, the Trustee for each series of Certificates will be Wilmington
Trust Company. With certain exceptions, the Trustee makes no representations as
to the validity or sufficiency of the Basic Agreement, the Trust Supplements,
the Certificates, the Equipment Notes, the Indentures, the Leases or other
related documents. The Trustee shall not be liable with respect to any series of
Certificates for any action taken or omitted to be taken by it in good faith in
accordance with the direction of the holders of a majority in principal amount
of outstanding Certificates of such series issued under the Basic Agreement.
Subject to such provisions, such Trustee shall be under no obligation to
exercise any of its rights or powers under the Basic Agreement at the request of
any holders of Certificates issued thereunder unless they shall have offered to
the Trustee indemnity satisfactory to it. The Basic Agreement provides that the
Trustee in its individual or any other capacity may acquire and hold
Certificates issued thereunder and, subject to certain conditions, may otherwise
deal with Atlas and, with respect to the Leased Aircraft, with any Owner Trustee
with the same rights it would have if it were not the Trustee.
 
The Trustee may resign with respect to any or all of the Trusts at any time, in
which event Atlas will be obligated to appoint a successor trustee. If the
Trustee ceases to be eligible to continue as Trustee with respect to a Trust or
becomes incapable of acting as Trustee or becomes insolvent, Atlas may remove
such Trustee, or any Certificateholder of such Trust for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of such Trustee and the appointment of
a successor trustee. Any resignation or removal of the Trustee with respect to a
Trust and appointment of a successor trustee for such Trust does not become
effective until acceptance of the appointment by the successor trustee. Pursuant
to such resignation and
                                       18
<PAGE>   37
 
successor trustee provisions, it is possible that a different trustee could be
appointed to act as the successor trustee with respect to each Trust. All
references in this Prospectus to the Trustee should be read to take into account
the possibility that the Trusts could have different successor trustees in the
event of such a resignation or removal.
 
The Basic Agreement provides that Atlas will pay the Trustee's fees and expenses
and indemnify the Trustee against certain liabilities.
 
                       DESCRIPTION OF THE EQUIPMENT NOTES
 
The statements made under this caption are summaries and reference is made to
the entire Prospectus and detailed information appearing in the applicable
Prospectus Supplement. Where no distinction is made between the Leased Aircraft
Notes and the Owned Aircraft Notes or between their respective Indentures, such
statements refer to any Equipment Notes and any Indenture.
 
To the extent that any provision in any Prospectus Supplement is inconsistent
with any provision in this summary, the provision of such Prospectus Supplement
will control.
 
GENERAL
 
Equipment Notes will be issued under Indentures either (a) between the related
Owner Trustee of a trust for the benefit of the Owner Participant who is the
beneficial owner of the related Aircraft, and the related Loan Trustee, or (b)
between Atlas and the related Loan Trustee. The Equipment Notes issued pursuant
to clause (a) of the preceding sentence will be nonrecourse obligations of the
applicable Owner Trust. Each Equipment Note will be authenticated under an
Indenture by the Loan Trustee. All Equipment Notes issued under the same
Indenture will relate to, and be secured by, one or more Aircraft identified and
described in the related Prospectus Supplement and which, in the case of the
Equipment Notes issued as described in such clause (a), are leased to Atlas
pursuant to a Lease between the Owner Trustee under the applicable Owner Trust
and Atlas or, in the case of Equipment Notes issued as described in clause (b),
owned by Atlas.
 
With respect to each Leased Aircraft, the related Owner Trustee has acquired or
will acquire such Aircraft, will grant a security interest in such Aircraft to
the related Loan Trustee as security for the payments of the related Leased
Aircraft Notes, and has leased or will lease such Aircraft to Atlas pursuant to
the related Lease which has been or will be assigned to the related Loan
Trustee. Pursuant to each such Lease, Atlas will be obligated to make or cause
to be made rental and other payments to the related Loan Trustee on behalf of
the related Owner Trustee.
 
PRINCIPAL AND INTEREST PAYMENTS
 
Interest received by the Trustee on the Equipment Notes held in each Trust will
be passed through to the Certificateholders of such Trust on the dates and at
the rate per annum set forth in the applicable Prospectus Supplement until the
final distribution for such Trust. Principal payments received by the Trustee on
the Equipment Notes held in each Trust will be passed through to the
Certificateholders of such Trust in scheduled amounts on the dates set forth in
the applicable Prospectus Supplement until the final distribution date for such
Trust.
 
                                       19
<PAGE>   38
 
If any date scheduled for any payment of principal, premium, if any, or interest
with respect to Equipment Notes is not a Business Day, such payment will be made
on the next succeeding Business Day without any additional interest.
 
REDEMPTION
 
The applicable Prospectus Supplement will describe the circumstances, whether
voluntary or involuntary, under which the Equipment Notes may be redeemed or
purchased prior to the stated maturity date thereof, in whole or in part, the
premium, if any, applicable upon certain redemptions or purchases and other
terms applying to the redemptions or purchases of such Equipment Notes.
 
SECURITY
 
The Leased Aircraft Notes will be secured by (i) an assignment by the related
Owner Trustee to the related Loan Trustee of such Owner Trustee's rights (except
for certain rights, including those described below) under the Lease or Leases
with respect to the related Aircraft, including the right to receive payments of
rent thereunder, and (ii) a mortgage granted to such Loan Trustee in such
Aircraft, subject to the rights of Atlas under such Lease or Leases. Under the
terms of each Lease, Atlas' obligations in respect of each Leased Aircraft will
be those of a Lessee under a "net lease". Accordingly, Atlas will be obligated,
among other things and at its expense, to cause each Leased Aircraft to be duly
registered, to pay all costs of operating such Aircraft and to maintain,
service, repair and overhaul (or cause to be maintained, serviced, repaired and
overhauled) such Aircraft. With respect to the Leased Aircraft, the assignment
by the related Owner Trustee to the related Loan Trustee of its rights under the
related Lease will exclude, among other things, rights of such Owner Trustee and
the related Owner Participant relating to indemnification by Atlas for certain
matters, insurance proceeds payable to such Owner Trustee in its individual
capacity and to such Owner Participant under liability insurance maintained by
Atlas pursuant to such Lease or by such Owner Trustee or such Owner Participant,
insurance proceeds payable to such Owner Trustee in its individual capacity or
to such Owner Participant under certain casualty insurance maintained by such
Owner Trustee or such Owner Participant pursuant to such Lease and any rights of
such Owner Participant or such Owner Trustee to enforce payment of the foregoing
amounts and their respective rights to the proceeds of the foregoing.
 
The Owned Aircraft Notes will be secured by a mortgage granted to the related
Loan Trustee of all of Atlas' right, title and interest in and to the Owned
Aircraft specified in the related Owned Aircraft Indenture. Under the terms of
each Owned Aircraft Indenture, Atlas will be obligated, among other things and
at its expense, to cause each Owned Aircraft to be duly registered, to pay all
costs of operating such Aircraft and to maintain, service, repair and overhaul
(or cause to be maintained, serviced, repaired and overhauled) such Aircraft.
 
The Prospectus Supplement will describe the required insurance coverage with
respect to the Aircraft.
 
Atlas will be required, except under certain circumstances, to keep each
Aircraft registered under the Transportation Code, and to record the Indenture
and the Lease, if applicable, among other documents, with respect to each
Aircraft under the Transportation Code. Such recordation of the Indenture, the
Lease, if applicable, and other documents with respect to each Aircraft will
give the related Loan Trustee a perfected security interest in the related
Aircraft whenever it is located in the United States or any of its territories
and
 
                                       20
<PAGE>   39
 
possessions; the Convention on the International Recognition of Rights in
Aircraft (the "Convention") provides that such security will also be recognized,
with certain limited exceptions, in those jurisdictions that have ratified or
adhere to the Convention. Atlas will have the right, subject to certain
conditions, at its own expense to register each Aircraft in countries other than
the United States. Each Aircraft may also be operated by Atlas or under lease,
sublease or interchange arrangements in countries that are not parties to the
Convention. The extent to which the related Loan Trustee's security interest
would be recognized in an Aircraft located in a country that is not a party to
the Convention, and the extent to which such security interest would be
recognized in a jurisdiction adhering to the Convention if the Aircraft is
registered in a jurisdiction not a party to the Convention, is uncertain.
Moreover, in the case of an Indenture Default, the ability of the related Loan
Trustee to realize upon its security interest in an Aircraft could be adversely
affected as a legal or practical matter if such Aircraft were registered or
located outside the United States.
 
Unless otherwise specified in the applicable Prospectus Supplement, the
Equipment Notes will not be cross-collateralized and consequently the Equipment
Notes issued in respect of any one Aircraft will not be secured by any other
Aircraft or, in the case of Leased Aircraft Notes, the Lease related thereto.
Unless and until an Indenture Default with respect to a Leased Aircraft has
occurred and is continuing, the related Loan Trustee may exercise only limited
rights of the related Owner Trustee under the related Lease.
 
Funds, if any, held from time to time by the Loan Trustee with respect to any
Aircraft, prior to the distribution thereof, will be invested and reinvested by
such Loan Trustee. Such investment and reinvestment will be at the direction of
Atlas (except, with respect to a Leased Aircraft, in the case of a Lease Event
of Default under the applicable Lease or, with respect to an Owned Aircraft, in
the case of an Indenture Default under the applicable Indenture or an incipient
payment default or incipient bankruptcy default), in certain investments
described in the applicable Indenture. The net amount of any loss resulting from
any such investments will be paid by Atlas.
 
Section 1110 of the U.S. Bankruptcy Code provides in relevant part that the
right of lessors, conditional vendors and holders of security interests with
respect to "equipment" (as defined in Section 1110 of the U.S. Bankruptcy Code)
to take possession of such equipment in compliance with the provisions of a
lease, conditional sale contract or security agreement, as the case may be, is
not affected by (a) the automatic stay provision of the U.S. Bankruptcy Code,
which provision enjoins repossessions by creditors for the duration of the
reorganization period, (b) the provision of the U.S. Bankruptcy Code allowing
the trustee in reorganization to use property of the debtor during the
reorganization period, (c) Section 1129 of the U.S. Bankruptcy Code (which
governs the confirmation of plans of reorganization in Chapter 11 cases) and (d)
any power of the bankruptcy court to enjoin a repossession. Section 1110
provides, however, in relevant part that the right of a lessor, conditional
vendor or holder of a security interest to take possession of an aircraft in the
event of an event of default may not be exercised for 60 days following the date
of commencement of the reorganization proceedings (unless specifically permitted
by the bankruptcy court) and may not be exercised at all if, within such 60-day
period (or such longer period consented to by the lessor, conditional vendor or
holder of a security interest), the trustee in reorganization agrees to perform
the debtor's obligations that become due on or after such date and cures all
existing defaults (other than defaults resulting solely from the financial
condition, bankruptcy, insolvency or reorganization of the debtor). "Equipment"
is defined in Section 1110 of the U.S. Bankruptcy Code, in part, as an aircraft,
aircraft engine, propeller, appliance, or spare part
 
                                       21
<PAGE>   40
 
(as defined in Section 40102 of Title 49 of the U.S. Code) that is subject to a
security interest granted by, leased to, or conditionally sold to a debtor that
is a citizen of the United States (as defined in Section 40102 of Title 49 of
the U.S. Code) holding an air carrier operating certificate issued by the
Secretary of Transportation pursuant to chapter 447 of Title 49 of the U.S. Code
for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more
of cargo (subject to certain limitations in the case of equipment first placed
in service on or prior to October 22, 1994).
 
In connection with any issuance of Certificates under this Prospectus and the
applicable Prospectus Supplement, it is a condition to the Trustee's obligation
to purchase Equipment Notes with respect to each Aircraft that outside counsel
to Atlas provide its opinion to such Trustee that (i) if such Aircraft is a
Leased Aircraft, the Owner Trustee, as lessor under the Lease for such Aircraft,
and the Loan Trustee, as assignee of such Owner Trustee's rights under such
Lease pursuant to the applicable Indenture, will be entitled to the benefits of
Section 1110 of the U.S. Bankruptcy Code with respect to the airframe and
engines comprising such Aircraft or (ii) if such Aircraft is an Owned Aircraft,
the Loan Trustee will be entitled to the benefits of Section 1110 with respect
to the airframe and engines comprising such Owned Aircraft, in each case so long
as Atlas continues to be a "citizen of the United States" as defined in Section
40102 of Title 49 of the U.S. Code holding an air carrier operating certificate
issued by the Secretary of Transportation pursuant to Chapter 447 of Title 49 of
the U.S. Code for aircraft capable of carrying 10 or more individuals or 6,000
pounds or more of cargo. Such opinion will not address the possible replacement
of an Aircraft after an Event of Loss (as defined in the Indenture) in the
future.
 
RANKING OF EQUIPMENT NOTES
 
Some of the Equipment Notes related to one or more Aircraft, as described in the
related Prospectus Supplement, may be subordinated and junior in right of
payment to other Equipment Notes related to the same Aircraft. The terms of such
subordination, if any, will be described in the related Prospectus Supplement.
 
PAYMENTS AND LIMITATION OF LIABILITY
 
Each Leased Aircraft will be leased by the related Owner Trustee to Atlas for a
term commencing on the delivery date thereof to such Owner Trustee and expiring
on a date not earlier than the latest maturity date of the related Leased
Aircraft Notes, unless previously terminated as permitted by the terms of the
related Lease. The basic rent and certain other payments under each such Lease
will be payable by Atlas and will assigned by the related Owner Trustee under
the applicable Indenture to the related Loan Trustee to provide the funds
necessary to pay principal of, premium, if any, and interest due from such Owner
Trustee on the Leased Aircraft Notes issued under such Indenture. In certain
cases, the basic rent payments under a Lease may be adjusted, but each Lease
will provide that under no circumstances will rent payments by Atlas be less
than the scheduled payments on the related Leased Aircraft Notes. The balance of
any basic rent payment under each Lease, after payment of amounts due on the
Leased Aircraft Notes issued under the Indenture corresponding to such Lease,
will be paid over to the applicable Owner Trustee. Atlas' obligation to pay rent
and to cause other payments to be made under each Lease will be general
obligations of Atlas.
 
With respect to the Leased Aircraft Notes, except in certain circumstances
involving Atlas' purchase of a Leased Aircraft and the assumption by Atlas of
certain obligations relating
 
                                       22
<PAGE>   41
 
thereto, including the obligation to make payments in respect of the related
Leased Aircraft Notes, the Leased Aircraft Notes will not be obligations of, or
guaranteed by, Atlas. With respect to the Leased Aircraft Notes, none of the
Owner Trustees, the Owner Participants or the Loan Trustees shall be personally
liable to any holder of such Leased Aircraft Notes for amounts payable under
such Leased Aircraft Notes, or, except as provided in the Indentures relating
thereto in the case of the Owner Trustees and the Loan Trustees, for any
liability under such Indentures. Except in the circumstances referred to above,
all amounts payable under any Leased Aircraft Notes (other than payments made in
connection with an optional redemption or purchase by the related Owner Trustee
or the related Owner Participant) will be made only from (i) the assets subject
to the lien of the applicable Indenture with respect to such Aircraft or the
income and proceeds received by the related Loan Trustee therefrom (including
rent payable by Atlas under the related Lease) or (ii) if so provided in the
related Prospectus Supplement, the applicable Liquidity Facility. With respect
to the Leased Aircraft Notes, except as otherwise provided in the applicable
Indenture, no Owner Trustee shall be personally liable for any amount payable or
for any statements, representations, warranties, agreements or obligations under
any such Indenture or under such Leased Aircraft Notes except for its own
willful misconduct or gross negligence. None of the Owner Participants shall
have any duty or responsibility under the Leased Aircraft Indentures or under
such Leased Aircraft Notes to the related Loan Trustee or to any holder of any
such Leased Aircraft Note.
 
Atlas' obligations under each Owned Aircraft Indenture and under the Owned
Aircraft Notes will be general obligations of Atlas.
 
DEFEASANCE OF THE INDENTURES AND THE EQUIPMENT NOTES IN CERTAIN CIRCUMSTANCES
 
Unless otherwise specified in the applicable Prospectus Supplement, each
Indenture provides that the obligations of the related Loan Trustee and, with
respect to any Leased Aircraft Notes, the related Owner Trustee or, with respect
to any Owned Aircraft Notes, Atlas under the applicable Indenture shall be
deemed to have been discharged and paid in full (except for certain obligations,
including the obligations to register the transfer or exchange of Equipment
Notes, to replace stolen, lost, destroyed or mutilated Equipment Notes and to
maintain paying agencies and hold money or payment in trust) on the 91st day
after the date of irrevocable deposit with the related Loan Trustee of money or
certain obligations of the United States or any agency or instrumentality
thereof the payment of which is backed by the full faith and credit of the
United States which, through the payment of principal and interest in respect
thereof in accordance with their terms, will provide money in an aggregate
amount sufficient to pay when due (including as a consequence of redemption in
respect of which notice is given on or prior to the date of such deposit)
principal of, premium, if any, and interest on all Equipment Notes issued
thereunder in accordance with the terms of such Indenture. Such discharge may
occur only if, among other things, (a) no event of default or event which with
the giving of notice or lapse of time, or both, would become an event of default
under such Indenture shall have occurred and be continuing on the date of such
deposit and (b) Atlas shall have delivered an opinion of counsel to the effect
that holders of such Equipment Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such deposit, defeasance and
discharge and will be subject to federal income tax on the same amount and in
the same manner and at the same time as would have been the case if such
deposit, defeasance and discharge had not occurred.
 
                                       23
<PAGE>   42
 
Upon such defeasance, or upon payment in full of the principal of, premium, if
any, and interest on all Equipment Notes issued under any Indenture on the
maturity date therefor or deposit with the applicable Loan Trustee of money
sufficient therefor no earlier than one year prior to the date of such maturity,
the holders of such Equipment Notes will have no beneficial interest in or other
rights with respect to the related Aircraft or other assets subject to the lien
of such Indenture and such lien shall terminate.
 
ASSUMPTION OF OBLIGATIONS BY ATLAS
 
Unless otherwise specified in the applicable Prospectus Supplement with respect
to Leased Aircraft, upon the exercise by Atlas of any purchase options it may
have under the related Lease prior to the end of the term of such Lease, Atlas
may assume on a full recourse basis all of the obligations of the Owner Trustee
(other than its obligations in its individual capacity) under the Indenture with
respect to such Aircraft, including the obligations to make payments in respect
of the related Leased Aircraft Notes. In such event, certain relevant provisions
of the related Lease, including (among others) provisions relating to
maintenance, possession and use of the related Aircraft, liens, insurance and
events of default will be incorporated into such Indenture, and the Leased
Aircraft Notes issued under such Indenture will not be redeemed and will
continue to be secured by such Aircraft.
 
LIQUIDITY FACILITY
 
The related Prospectus Supplement may provide that one or more payments of
interest on the related Equipment Notes of one or more series will be supported
by a Liquidity Facility issued by an institution identified in the related
Prospectus Supplement. Unless otherwise provided in the related Prospectus
Supplement, the provider of the Liquidity Facility will have a senior claim upon
the assets securing the Equipment Notes.
 
INTERCREDITOR ISSUES
 
Equipment Notes may be issued in different Classes, which means that the
Equipment Notes may have different payment priorities even though they are
issued by the same borrower and relate to the same Aircraft. In such event, the
related Prospectus Supplement will describe the priority of distributions among
such Equipment Notes (and any Liquidity Facilities therefor), the ability of any
Class to exercise and/or enforce any or all remedies with respect to the related
Aircraft (and, if the Equipment Notes are Leased Aircraft Notes, the Lease
related thereto) and certain other intercreditor terms and provisions.
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
Unless otherwise indicated in the applicable Prospectus Supplement, the
following summary describes the material U.S. federal income tax consequences to
Certificateholders of the purchase, ownership and disposition of the
Certificates offered hereby and in the opinion of Cahill Gordon & Reindel,
special tax counsel to Atlas ("Tax Counsel"), is accurate in all material
respects. Except as otherwise specified, the summary is addressed to beneficial
owners of Certificates ("U.S. Certificateholders") that are citizens or
residents of the United States, corporations, partnerships or other entities
created or organized in or under the laws of the United States or any state
therein, estates the
 
                                       24
<PAGE>   43
 
income of which is subject to U.S. federal income taxation regardless of its
source and trusts that meet the following two tests: (a) a U.S. court is able to
exercise primary supervision over the administration of the trust and (b) one or
more United States persons have the authority to control all the substantial
decisions of such trust ("U.S. Persons") that will hold the Certificates as
capital assets. This summary does not address the tax treatment of U.S.
Certificateholders that may be subject to special tax rules, such as banks,
insurance companies, dealers in securities or commodities, tax-exempt entities,
holders that will hold Certificates as part of a straddle or holders that have a
"functional currency" other than the U.S. dollar, nor, except as specifically
indicated, does it address the tax treatment of U.S. Certificateholders that do
not acquire Certificates at the initial offering price as part of the initial
offering thereof. The summary does not purport to be a comprehensive description
of all of the tax considerations that may be relevant to a decision to purchase
Certificates. This summary does not describe any tax consequences arising under
the laws of any state, locality or taxing jurisdiction other than the United
States.
 
The summary is based upon the tax laws of the United States as in effect on the
date of this Prospectus, as well as judicial and administrative interpretations
thereof available on or before such date. All of the foregoing are subject to
change, which change could apply retroactively. Prospective investors should
note that no rulings have been sought from the Internal Revenue Service (the
"IRS") with respect to the federal income tax consequences discussed below, and
no assurances can be given that the IRS will not take contrary positions. The
Trusts are not indemnified for any U.S. federal income taxes that may be imposed
upon them, and the imposition of any such taxes on a Trust could result in a
reduction in the amounts available for distribution to the Certificateholders of
such Trust. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH
RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE
PURCHASE, OWNERSHIP AND DISPOSITION OF THE CERTIFICATES.
 
TAX STATUS OF THE TRUSTS
 
In the opinion of Tax Counsel, each Trust will be classified as a grantor trust
for U.S. federal income tax purposes.
 
TAXATION OF CERTIFICATEHOLDERS GENERALLY
 
A U.S. Certificateholder will be treated as owning its pro rata undivided
interest in each of the Equipment Notes and any other property held by the
related Trust. Accordingly, each U.S. Certificateholder's share of interest paid
on the Equipment Notes will be taxable as ordinary income, as it is paid or
accrued, in accordance with such U.S. Certificateholder's method of accounting
for U.S. federal income tax purposes, and a U.S. Certificateholder's share of
premium, if any, paid on redemption of an Equipment Note will be treated as
capital gain. In the event that a Trust is supported by a Liquidity Facility,
any amounts received by the Trust under the Liquidity Facility with respect to
unpaid interest will be treated for U.S. federal income tax purposes as having
the same characteristics as the payments they replace. If Atlas were to assume
an Owner Trust's obligations under Leased Aircraft Notes, such assumption would
be treated for federal income tax purposes as a taxable exchange of such Leased
Aircraft Notes, resulting in recognition of taxable gain or loss by the U.S.
Certificateholder.
 
Each U.S. Certificateholder will be entitled to deduct, consistent with its
method of accounting, its pro rata share of fees and expenses paid or incurred
by the corresponding
 
                                       25
<PAGE>   44
 
Trust as provided in Section 162 or 212 of the Code. Certain fees and expenses,
including fees paid to the Trustee and Liquidity Facility providers (if
applicable), will be borne by parties other than the Certificateholders. It is
possible that such fees and expenses will be treated as constructively received
by the Trust, in which event a U.S. Certificateholder will be required to
include in income and will be entitled to deduct its pro rata share of such fees
and expenses. If a U.S. Certificateholder is an individual, estate or trust, the
deduction for such holder's share of such fees or expenses will be allowed only
to the extent that all of such holder's miscellaneous itemized deductions,
including such holder's share of such fees and expenses, exceed 2% of such
holder's adjusted gross income. In addition, in the case of U.S.
Certificateholders who are individuals, certain otherwise allowable itemized
deductions will be subject generally to additional limitations on itemized
deductions under applicable provisions of the Code.
 
EFFECT OF SUBORDINATION OF SUBORDINATED CERTIFICATEHOLDERS
 
In the event that any Trust (such Trust being a "Subordinated Trust" and the
related Certificates being "Subordinated Certificates") is subordinated in right
of payment to any other Trust and the Subordinated Trust receives less than the
full amount of the receipts of interest, principal or premium paid with respect
to the Equipment Notes held by it (any shortfall in such receipts being the
"Shortfall Amounts") because of the subordination of such Trust, the
corresponding owners of beneficial interests in the Subordinated Certificates
(the "Subordinated Certificateholders") would probably be treated for federal
income tax purposes as if they had (1) received as distributions their full
share of such receipts, (2) paid over to the relevant preferred class of
Certificateholders an amount equal to their share of such Shortfall Amount, and
(3) retained the right to reimbursement of such amounts to the extent of future
amounts payable to such Subordinated Certificateholders with respect to such
Shortfall Amount.
 
Under this analysis, (1) Subordinated Certificateholders incurring a Shortfall
Amount would be required to include as current income any interest or other
income of the corresponding Subordinated Trust that was a component of the
Shortfall Amount, even though such amount was in fact paid to the relevant
preferred class of Certificateholders, (2) a loss would only be allowed to such
Subordinated Certificateholders when their right to receive reimbursement of
such Shortfall Amount becomes worthless (i.e., when it becomes clear that funds
will not be available from any source to reimburse such loss), and (3)
reimbursement of such Shortfall Amount prior to such a claim of worthlessness
would not be taxable income to Subordinated Certificateholders because such
amount was previously included in income. These results should not significantly
affect the inclusion of income for Subordinated Certificateholders on the
accrual method of accounting, but could accelerate inclusion of income to
Subordinated Certificateholders on the cash method of accounting by, in effect,
placing them on the accrual method.
 
ORIGINAL ISSUE DISCOUNT
 
The Equipment Notes may be issued with original issue discount ("OID"). The
applicable Prospectus Supplement will state whether any Equipment Notes to be
held by the related Trust will be issued with OID and, if applicable, will
describe the special U.S. federal income tax rules governing debt instruments
issued with OID. Generally, a holder of a debt instrument issued with OID that
is not de minimis must include such OID in income for federal income tax
purposes as it accrues, in advance of the receipt of the cash attributable to
such income, under a method that takes into account the compounding of interest.
 
                                       26
<PAGE>   45
 
SALE OR OTHER DISPOSITION OF THE CERTIFICATES
 
Upon the sale, exchange or other disposition of a Certificate, a U.S.
Certificateholder generally will recognize capital gain or loss (subject to the
possible recognition of ordinary income under market discount rules) equal to
the difference between the amount realized on the disposition (other than any
amount attributable to accrued interest which will be taxable as ordinary
income) and the U.S. Certificateholder's adjusted tax basis in the related Note
Purchase Agreement, Equipment Notes and any other property held by the
corresponding Trust. Any gain or loss will be long-term capital gain or loss to
the extent attributable to property held by the Trust for more than one year. In
the case of individuals, estates and trusts, long-term capital gains generally
are taxable at a lower rate than short-term capital gains. Any gain with respect
to an interest in a Deposit likely will be treated as ordinary income.
 
FOREIGN CERTIFICATEHOLDERS
 
Subject to the discussion of backup withholding below, payments of principal and
interest on the Equipment Notes to, or on behalf of, any beneficial owner of a
Certificate that is not a U.S. Person (a "Non-U.S. Certificateholder") will not
be subject to U.S. federal withholding tax; provided, in the case of interest,
that (i) such Non-U.S. Certificateholder does not actually or constructively own
10% or more of the total combined voting power of all classes of the stock of
Atlas or any Owner Participant or any transferee of such Owner Participant's
interest in the relevant Owner Trust, (ii) such Non-U.S. Certificateholder is
not a controlled foreign corporation for U.S. tax purposes that is related to
Atlas or any Owner Participant or any transferee of such Owner Participant's
interest in the relevant Owner Trust and (iii) either (A) the Non-U.S.
Certificateholder certifies, under penalties of perjury, that it is not a U.S.
person and provides its name and address or (B) a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "financial
institution") and holds the Certificate certifies, under penalties of perjury,
that such statement has been received from the Non-U.S. Certificateholder by it
or by another financial institution and furnishes the payor with a copy thereof.
The IRS issued final regulations on October 6, 1997, which modify the
certification requirements described in clause (iii) with respect to certain
payments after December 31, 1998.
 
Any capital gain realized upon the sale, exchange, retirement or other
disposition of a Certificate or upon receipt of premium paid on an Equipment
Note by a Non-U.S. Certificateholder will not be subject to U.S. federal income
or withholding taxes if (i) such gain is not effectively connected with a U.S.
trade or business of the Non-U.S. Certificateholder and (ii) in the case of an
individual, such Non-U.S. Certificateholder is not present in the United States
for 183 days or more in the taxable year of the sale, exchange, retirement or
other disposition or receipt.
 
BACKUP WITHHOLDING
 
Payments made on the Certificates and proceeds from the sale of Certificates
will not be subject to a backup withholding tax of 31% unless, in general, the
Certificateholder fails to comply with certain reporting procedures or otherwise
fails to establish an exemption from such tax under applicable provisions of the
Code.

<PAGE>   46
 
                              ERISA CONSIDERATIONS
 
Unless otherwise indicated in the applicable Prospectus Supplement, the
Certificates may, subject to certain legal restrictions, be purchased and held
by an employee benefit plan (a "Plan") subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or an individual
retirement account or an employee benefit plan subject to section 4975 of the
Code. A fiduciary of a Plan must determine that the purchase and holding of a
Certificate is consistent with its fiduciary duties under ERISA and does not
result in a non-exempt prohibited transaction as defined in section 406 of ERISA
or section 4975 of the Code. Employee benefit plans which are governmental plans
(as defined in section 3(32) of ERISA) and certain church plans (as defined in
section 3(33) of ERISA) are not subject to Title I of ERISA or section 4975 of
the Code. The Certificates may, subject to certain legal restrictions, be
purchased and held by such plans.
 
                              PLAN OF DISTRIBUTION
 
Certificates may be sold to one or more underwriters for public offering and
sale by them or to investors or other persons directly or through one or more
dealers or agents. Any such underwriter, dealer or agent involved in the offer
and sale of the Certificates will be named in an applicable Prospectus
Supplement.
 
The Certificates may be sold at a fixed price or prices, which may be changed,
or from time to time at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. Dealer trading
may take place in certain of the Certificates, including Certificates not listed
on any securities exchange. Atlas does not intend to apply for listing of the
Certificates on a national securities exchange. Atlas also may, from time to
time, authorize underwriters acting as Atlas' agents to offer and sell the
Certificates upon the terms and conditions as shall be set forth in any
Prospectus Supplement. In connection with the sale of Certificates, underwriters
may be deemed to have received compensation from Atlas in the form of
underwriting discounts or commissions and may also receive commissions from
purchasers of Certificates for whom they may act as agent. Underwriters may sell
Certificates to or through dealers, and such dealers may receive compensation in
the form of discounts, concessions or commissions from the underwriters and/or
commissions (which may be changed from time to time) from the purchasers for
whom they may act as agent.
 
If a dealer is used directly by Atlas in the sale of Certificates in respect of
which this Prospectus is delivered, such Certificates will be sold to the
dealer, as principal. The dealer may then resell such Certificates to the public
at varying prices to be determined by such dealer at the time of resale. Any
such dealer and the terms of any such sale will be set forth in the Prospectus
Supplement relating thereto.
 
Certificates may be offered and sold through agents designated by Atlas from
time to time. Any such agent involved in the offer or sale of the Certificates
in respect of which this Prospectus is delivered will be named in, and any
commission payable by Atlas to such agent will be set forth in, the applicable
Prospectus Supplement. Unless otherwise indicated in the applicable Prospectus
Supplement, any such agent will be acting on a best efforts basis for the period
of its appointment.
 
Offers to purchase Certificates may be solicited directly by Atlas and sales
thereof may be made by Atlas directly to institutional investors or others who
may be deemed to be underwriters within the meaning of the Securities Act with
respect to any resale thereof.
 
                                       28
<PAGE>   47
 
The terms of any such sales will be described in the Prospectus Supplement
relating thereto. Except as set forth in the applicable Prospectus Supplement,
no director, officer or employee of Atlas will solicit or receive a commission
in connection with direct sales by Atlas of the Certificates, although such
persons may respond to inquiries by potential purchasers and perform ministerial
and clerical work in connection with any such direct sales.
 
Any underwriting compensation paid by Atlas to underwriters, dealers or agents
in connection with the offering of Certificates, and any discounts, concessions
or commissions allowed by underwriters to participating dealers, will be set
forth in an applicable Prospectus Supplement. Underwriters, dealers and agents
participating in the distribution of the Certificates may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the Certificates may be deemed to be underwriting
discounts and commissions under the Securities Act. Underwriters, dealers and
agents may be entitled, under agreements with Atlas, to indemnification against
and contribution toward certain civil liabilities, including liabilities under
the Securities Act, and to reimbursement by Atlas for certain expenses.
 
Underwriters, dealers and agents may engage in transactions with, or perform
services for, Atlas and its subsidiaries in the ordinary course of business.
 
If so indicated in an applicable Prospectus Supplement and subject to existing
market conditions, Atlas will authorize dealers acting as Atlas' agents to
solicit offers by certain institutions to purchase Certificates at the public
offering price set forth in such Prospectus Supplement pursuant to Delay
Delivery Contracts ("Contracts") providing for payment and delivery on the date
or dates stated in such Prospectus Supplement. Each Contract will be for an
amount not less than, and the aggregate principal amount of Certificates sold
pursuant to Contracts shall not be less nor more than, the respective amounts
stated in such Prospectus Supplement. Institutions with whom Contracts, when
authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions and other institutions, but will in all cases be subject to the
approval of Atlas. Contracts will not be subject to any conditions except the
purchase by an institution of the Certificates covered by its Contracts shall
not at the time of delivery be prohibited under the laws of any jurisdiction in
the United States to which such institution is subject. A commission indicated
in the applicable Prospectus Supplement will be granted to underwriters and
agents soliciting purchases of Certificates pursuant to Contracts accepted by
Atlas. Agents and underwriters will have no responsibility in respect of the
delivery or performance of Contracts.
 
If an underwriter or underwriters are utilized in the sale of any Certificates,
the applicable Prospectus Supplement will contain a statement as to the
intention, if any, of such underwriters at the date of such Prospectus
Supplement to make a market in the Certificates. No assurances can be given that
there will be a market for the Certificates.
 
The place and time of delivery for the Certificates in respect of which this
Prospectus is delivered will be set forth in the applicable Prospectus
Supplement.

ITEM 17. UNDERTAKINGS.
 
The undersigned Registrant hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
     (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933 ("Securities Act");
 
     (ii) To reflect in the prospectus any facts or events arising after the
     effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement; and
 
     (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement;
 
     provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed pursuant to Section 13 or
     Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
     by reference in the registration statement.
 
(2) That, for the purpose of determining any liability under the Securities Act,
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.
 
                                      II-8
<PAGE>   57
 
(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
(4) That, for purposes of determining any liability under the Securities Act,
each filing of the registrant's annual report pursuant to Section 13(a) or 15(d)
of the Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement 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.
 
The undersigned registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to section 13(a) or section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement 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.
 
The undersigned registrant hereby undertakes to deliver or cause to be delivered
with the prospectus, to each person to whom the prospectus is sent or given, the
latest annual report to security holders that is incorporated by reference in
the prospectus and furnished pursuant to and meeting the requirements of Rule
14a-3 or Rule 14c-3 under the Securities Exchange act of 1934; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X are not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.
 
The undersigned registrant hereby undertakes that:
 
(1) For purposes of determining any liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
(2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus 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 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 Commission such indemnification is against
public policy as expressed in the Securities 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 such 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 Securities Act and will be governed by the final
adjudication of such issue.

     a possible change that does not indicate the direction of the possible
     change, in the rating accorded any of the Company's securities by any
     "nationally recognized statistical rating organization," as such term is
     defined for purposes of Rule 436(g)(2) under the Act; and

          (ii) there shall not have occurred any change, or any development
     involving a prospective change, in the condition, financial or otherwise,
     or in the earnings, business or operations of the Company and its
     Subsidiaries, taken as a whole, from that set forth in the Final Prospectus
     (exclusive of any amendments or supplements thereto subsequent to the date
     of this Agreement) that, in your judgment, is material and adverse and that
     makes it, in your judgment, impracticable to market the Shares on the terms
     and in the manner contemplated in the Final Prospectus.

     (b) (i) The Underwriters shall have received on the Closing Date a
  certificate, dated the Closing Date and signed by an executive officer of the
  Company, to the effect set forth in Section 6(a)(i) above and to the effect
  that the representations and warranties of the Company contained in this
  Agreement are true and correct as of the Closing Date and that the Company has
  complied with all of the agreements and satisfied all of the conditions on its
  part to be performed or satisfied hereunder on or before the Closing Date.

          (ii) The Underwriters shall have received on the Closing Date a
     certificate, dated the Closing Date from each Selling Stockholder signed by
     an officer of a corporation, a general partner of a limited partnership, a
     member of a limited liability company or a trustee of a trust from each
     Selling Stockholder that is a corporation, limited partnership or trust,
     respectively, to the effect that the representations and warranties of each
     Selling Stockholder contained in Section 2 of this Agreement are true and
     correct as of the Closing Date and that each Selling Stockholder has
     complied with all of the agreements and satisfied all of the conditions on
     its part to be performed or satisfied hereunder on or before the Closing
     Date. The officer, general partner or trustee, as the case may be, signing
     and delivering such

                                      -16-


     certificate may rely upon the best of his or her knowledge as to
     proceedings threatened.

     (c) The Underwriters shall have received on the Closing Date an opinion of
  Cahill Gordon & Reindel, outside counsel for the Company, dated the Closing
  Date, to the effect that:

          (i) The Company has been duly incorporated and is validly existing as
     a corporation and is in good standing under the laws of the State of
     Delaware with corporate power and authority under such laws to own, lease
     and operate its properties and conduct its business as described in the
     Final Prospectus.

          (ii) The Shares sold by the Company pursuant to the provisions of this
     Agreement against the consideration set forth in this Agreement, have been
     duly authorized and validly issued and are fully paid and non-assessable;
     such Shares are not subject to the preemptive rights of any stockholder of
     the Company, and all corporate action required to be taken for the
     authorization, issue and sale of such Shares has been validly and
     sufficiently taken.

          (iii) The authorized, issued and outstanding capital stock of the
     Company is as set forth in the Final Prospectus under the heading
     "Capitalization".

          (iv) The Shares conform in all material respects as to legal matters
     to the description thereof in the Final Prospectus.

          (v) This Agreement has been duly authorized, executed and delivered by
     the Company.

          (vi) No authorization, approval, consent or license of any government,
     governmental instrumentality or court, domestic or foreign (other than
     under the Act, the Exchange Act and the securities or blue sky laws of the
     various states), is required for the valid authorization, issuance, sale
     and delivery of the Shares.

          (vii) The statements made in the Final Prospectus under "Description
     of Capital Stock" and [ ], to the extent that they constitute matters of
     law or legal conclusions, have

<PAGE>   18
                                      -17-


     been reviewed by such counsel and fairly present the information disclosed
     therein in all material respects.

          (viii) The Company is not and, after giving effect to the offering and
     sale of the Shares and the application of the proceeds thereof as described
     in the Final Prospectus, will not be an "investment company" or an entity
     "controlled" by an "investment company", as such terms are defined in the
     Investment Company Act of 1940, as amended.

          (ix) The execution and delivery of this Agreement, the issuance and
     delivery of the Shares, the consummation by the Company of the transactions
     contemplated in this Agreement and in the Final Prospectus and compliance
     by the Company with the terms of this Agreement do not and will not result
     in any violation of the charter or by-laws of the Company or any
     Subsidiary, and do not and will not conflict with, or result in a breach of
     any of the terms or provisions of, or constitute a default under, or result
     in the creation of or imposition of any lien, charge or encumbrance upon
     any property or assets of the Company or any Subsidiary under any contract,
     indenture, loan agreement, note, lease or other agreement or instrument
     that is filed as an exhibit to the Registration Statement (except for such
     conflicts, breaches or defaults or liens, charges or encumbrances that
     would not have a material adverse effect on the condition (financial or
     otherwise) of the Company and its Subsidiaries, considered as one
     enterprise).

          (x) The Registration Statement, the Final Prospectus and each
     amendment or supplement thereto (except for the financial statements and
     other financial or statistical data included therein or omitted therefrom,
     as to which such counsel need express no opinion), as of their respective
     effective or issue dates, appear on their face to comply as to form in all
     material respects to the requirements of the Act and the regulations
     thereunder.

          (xi) Such counsel have participated in conferences with officers and
     other representatives of the Company, representatives of the independent
     public accountants for the Company, representatives of the

<PAGE>   19
                                      -18-


     Underwriters and counsel for the Underwriters, at which the contents of the
     Registration Statement and Final Prospectus and related matters were
     discussed. Although such counsel are not passing upon and do not assume any
     responsibility for the accuracy, completeness or fairness of the statements
     contained in the Registration Statement and Final Prospectus (except as
     specified in clauses (iv) and (vii) above), on the basis of the foregoing
     (relying as to materiality to a large extent on discussions with, and
     representations and opinions of officers and other representatives of the
     Company), and no facts have come to the attention of such counsel to lead
     them to believe (A) that the Registration Statement or any amendment
     thereto (except for the financial statements and other financial or
     statistical data included therein or omitted therefrom, as to which such
     counsel need express no opinion), at the time the Registration Statement or
     any such amendment became effective, contained or contains an untrue
     statement of a material fact or omitted to state a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading or (B) that the Final Prospectus or any amendment or supplement
     thereto (except for the financial statements and other financial or
     statistical data included therein or omitted therefrom, as to which such
     counsel need express no opinion), at the time the Final Prospectus was
     issued, at the time any such amended or supplemented prospectus was issued
     or at the Closing Time, included or includes an untrue statement of a
     material fact or omitted or omits to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. If at the time the opinion is
     delivered, no amendment to the Registration Statement or amendment or
     supplement to the Final Prospectus has been filed or issued, such opinion
     need not opine as to any such amendment or supplement.

Such opinion shall be to such further effect with respect to other legal matters
relating to this Agreement and the sale of the Shares pursuant to this Agreement
as counsel for the Underwriters may reasonably request. In giving such opinion,
such counsel may rely, as to all matters governed by the laws of jurisdictions
other than the law of the State of New York, the federal law of the United
States and the General Corporation Law of the State of Delaware, upon opinions
of other counsel,

<PAGE>   20
                                      -19-


who shall be counsel satisfactory to counsel for the Underwriters in which case
the opinion shall state that they believe you and they are entitled to so rely.
Such counsel may also state that, insofar as such opinion involves factual
matters, they have relied, to the extent they deem proper, upon certificates of
officers of the Company and certificates of public officials; provided that such
certificates have been delivered to the Underwriters.

     (d) ___ of an opinion of _______, General Counsel for the Company, dated as
  of the Closing Time, together with reproduced copies of such opinion for each
  of the other Underwriters, in form and substance satisfactory to counsel for
  the Underwriters, to the effect that:

          (i) The Company is duly qualified to transact business as a foreign
     corporation and is in good standing in each other jurisdiction in the
     United States in which it owns or leases property of a nature, or transacts
     business of a type, that would make such qualification necessary, except to
     the extent that the failure to so qualify or be in good standing would not
     have a material adverse effect on the Company and its Subsidiaries,
     considered as one enterprise.

          (ii) Each Subsidiary is a corporation duly organized under the laws of
     its jurisdiction of incorporation and is duly qualified to transact
     business as a foreign corporation and is in good standing in each other
     jurisdiction in which it owns or leases property of a nature, or transacts
     business of a type, that would make such qualification necessary, except to
     the extent that the failure to so qualify or be in good standing would not
     have a material adverse effect on the Company and its Subsidiaries,
     considered as one enterprise.

          (iii) All of the other outstanding shares of capital stock of the
     Company, including shares sold by the Selling Shareholders pursuant to the
     provisions of this Agreement, have been duly authorized and validly issued
     and are fully paid and non-assessable; and none of the outstanding shares
     of capital stock of the Company was issued in violation of the preemptive
     rights arising under the Restated Certificate of Incorporation of the
     Company or under Delaware General Corporation Law.

                                      -20-


          (iv) Such counsel does not know of any statutes or regulations, or any
     pending or threatened legal or governmental proceedings, required to be
     described in the Final Prospectus that are not described as required, nor
     of any contracts or documents of a character required to be described or
     referred to in the Registration Statement or the Final Prospectus or to be
     filed as exhibits to the Registration Statement that are not described,
     referred to or filed as required.

          (v) The descriptions in the Final Prospectus of the statutes,
     regulations, legal or governmental proceedings and the statements under
     "Business -- Governmental Regulations", are accurate, and to the extent
     that they constitute matters of law or legal conclusions, have been
     reviewed by such counsel and fairly represent the information disclosed
     therein in all material respects.

          (vi) The Company is an "air carrier" and a "citizen of the United
     States" within the meaning of that portion of the United States Code
     comprising those provisions formerly referred to as the Federal Aviation
     Act of 1958, and now primarily codified in Title 49 of the United States
     Code, as amended (the "Aviation Act") and holds an "air carrier operating
     certificate issued by the Secretary of Transportation" within the meaning
     of 11 U.S.C. Section 1110. The statements in the Final Prospectus as to the
     routes relating to its services which the Company presently operates or is
     authorized to operate are correct in all material respects and such routes
     presently operated are being operated pursuant to valid Certificates or
     Exemption Orders issued by the Department of Transportation, and no such
     Certificate or Exemption Order is the subject of any "show cause" or other
     order of, or any proceeding before, or any investigation by, the Department
     of Transportation, which in the opinion of such counsel might reasonably
     result in a final order impairing the validity of such Certificates or
     Exemption Orders.

          (vii) To the knowledge of such counsel, no default exists in the
     performance or observance of any material obligation, agreement, covenant
     or condition contained in any contract, indenture, loan agreement, note,
     lease or other agreement or instrument that is

<PAGE>   22
                                      -21-


     described or referred to in the Registration Statement or the Final
     Prospectus or filed as an exhibit to the Registration Statement, except for
     such defaults that would not have a material adverse effect on the
     condition (financial or otherwise) of the Company and its Subsidiaries,
     considered as one enterprise.

          (viii) The execution and delivery of this Agreement, the issuance and
     delivery of the Shares, the consummation by the Company of the transactions
     contemplated in this Agreement and in the Registration Statement and
     compliance by the Company with the terms of this Agreement do not conflict
     with, or result in a breach of any of the terms or provisions of, or
     constitute a default under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any property or assets of the Company or
     any Subsidiary under (A) any contract, indenture, mortgage, loan agreement,
     note, lease or any other agreement or instrument known to such counsel, to
     which the Company or any Subsidiary is a party or by which it may be bound
     or to which any of its properties may be subject (except for such
     conflicts, breaches or defaults or liens, charges or encumbrances that
     would not have a material adverse effect on the condition (financial or
     otherwise), earnings, business affairs or business prospects of the Company
     and any Subsidiary, considered as one enterprise), (B) any existing
     applicable law, rule or regulation (other than the securities or blue sky
     laws of the various states, as to which such counsel need express no
     opinion) or (C) any judgment, order or decree of any government,
     governmental instrumentality or court, domestic or foreign, having
     jurisdiction over the Company or the Subsidiary or any of their respective
     properties (except for such conflicts, breaches or defaults or liens,
     charges or encumbrances that would not have a material adverse effect on
     the condition (financial or otherwise)) of the Company and any Subsidiary,
     considered as one enterprise.

          (ix) Such counsel has participated in the preparation of the
     Registration Statement and Final Prospectus. Although such counsel is not
     passing upon and does not assume any responsibility for the accuracy,
     completeness or fairness of the statements contained in the Registration
     Statement and Final

<PAGE>   23
                                      -22-


     Prospectus (except as specified in clauses (v) and (vi) above), on the
     basis of the foregoing (relying as to materiality to a large extent on
     discussions with, and representations and opinions of officers and other
     representatives of the Company), no facts have come to the attention of
     such counsel to lead him to believe (A) that the Registration Statement or
     any amendment thereto (except for the financial statements and other
     financial or statistical data included therein or omitted therefrom, as to
     which such counsel need express no opinion), at the time the Registration
     Statement or any such amendment became effective, contained or contains an
     untrue statement of a material fact or omitted to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading or (B) that the Final Prospectus or any amendment or
     supplement thereto (except for the financial statements and other financial
     or statistical data included therein or omitted therefrom, as to which such
     counsel need express no opinion), at the time the Final Prospectus was
     issued, at the time any such amended or supplemented prospectus was issued
     or at the Closing Time, included or includes an untrue statement of a
     material fact or omitted or omits to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading.

Such opinion shall be to such further effect with respect to other legal matters
relating to this Agreement and the sale of the Shares pursuant to this Agreement
as counsel for the Underwriters may reasonably request. In giving such opinion,
such counsel may rely, as to all matters governed by the laws of jurisdictions
other than the law of the District of Columbia, the federal law of the United
States, the State of Colorado, and the General Corporation Law of the State of
Delaware, upon opinions of other counsel, who shall be counsel satisfactory to
counsel for the Underwriters, in which case the opinion shall state that they
believe you and they are entitled to so rely. Such counsel may also state that,
insofar as such opinion involves factual matters, they have relied, to the
extent they deem proper, upon certificates of officers of the Company and
certificates of public officials; provided that such certificates have been
delivered to the Underwriters.

                                      -23-


     (e) An opinion of         , counsel for the Selling Stockholders, together
  with reproduced copies of such opinion for each of the other Underwriters, to
  the effect that:

          (i) this Agreement has been duly authorized, executed and delivered by
     or on behalf of each of the Selling Stockholders;

          (ii) the execution and delivery by each Selling Stockholder of, and
     the performance by such Selling Stockholder of his or its obligations under
     this Agreement will not contravene any provision of applicable law, or the
     certificate of incorporation or by-laws or certificate of limited
     partnership of such Selling Stockholder (if such Selling Stockholder is a
     corporation or a partnership) or any stockholders' agreement among such
     Selling Stockholders or, to the best of such counsel's knowledge, any
     agreement or other instrument binding upon such Selling Stockholder or, to
     the best of such counsel's knowledge, any judgment, order or decree of any
     governmental body, agency or court having jurisdiction over such Selling
     Stockholder, and no consent, approval, authorization or order of, or
     qualification with, any governmental body or agency is required for the
     performance by such Selling Stockholder of his or its obligations under
     this Agreement except the order of the Commission declaring the
     Registration Statement effective and such as may be required by the
     securities or blue sky laws of the various states in connection with offer
     and sale of the Shares (as to which securities laws such counsel expresses
     no opinion);

          (iii) each of the Selling Stockholders has valid title to the Shares
     to be sold by such Selling Stockholder and the legal right and power, and
     all authorization and approval required by law, to enter into this
     Agreement and to sell, transfer and deliver the Shares to be sold by such
     Selling Stockholder; and

          (iv) delivery of the Shares to be sold by such Selling Stockholder and
     payment therefor by the Underwriters pursuant to this Agreement will pass
     title to such Shares free and clear of any security interests, claims,
     liens, equities and other encumbrances.

<PAGE>   25
                                      -24-


     Such opinion shall be to such further effect with respect to other legal
     matters relating to this Agreement and the sale of the Shares pursuant to
     this Agreement as counsel for the Underwriters may reasonably request. In
     giving such opinion, such counsel may rely, as to all matters governed by
     the laws of jurisdictions other than the law of the State of [          ]
     or [      ] and the current laws of the United States, upon opinions of
     other counsel, who shall be counsel satisfactory to counsel for the
     Underwriters, in which case the opinion shall state that they believe you
     and they are entitled to so rely. For purposes of such opinion, the term
     "to the best of such counsel's knowledge" means the conscious awareness of
     facts or other information by the lawyer who signs such opinion and other
     lawyers at such counsel's firm who have active involvement in representing
     either of the Selling Stockholders. Such counsel may also state that,
     insofar as such opinion involves factual matters, they have relied, to the
     extent they deem proper, upon certificates of the Selling Stockholders,
     officers of the Company, certificates of public officials and a certificate
     of the transfer agent of the Company; provided that such certificates have
     been delivered to the Underwriters. Such counsel need express no opinion as
     to compliance with federal or state securities laws or any aviation law,
     including without limitation, the Aviation Act. Further, in giving such
     opinion, such counsel may assume that all natural persons who are
     signatories to any documents are legally competent at the time of
     execution, that the Representatives have no notice of any claim that a
     transfer of the Shares by the Selling Stockholders is wrongful or that a
     particular adverse person is the owner of or has any interest in such
     Shares, and that all signatures on documents reviewed by such counsel are
     genuine.

          With respect to Section 6(e) above, the Selling Stockholders' Counsels
     may rely upon an opinion or opinions of counsel for any Selling
     Stockholders and, with respect to factual matters and to the extent such
     counsel deems appropriate, upon the representations of each Selling
     Stockholder contained herein and in the Custody Agreement and Power of
     Attorney of such Selling Stockholder and in other docu-

<PAGE>   26
                                      -25-


     ments and instruments; provided that (A) each such counsel for the Selling
     Stockholders is satisfactory to your counsel, (B) a copy of each opinion so
     relied upon is delivered to you and is in form and substance satisfactory
     to your counsel, (C) copies of such Custody Agreements and Powers of
     Attorney and of any such other documents and instruments shall be delivered
     to you and shall be in form and substance satisfactory to your counsel and
     (D) the Selling Stockholders' Counsels shall state in their opinion that
     they are justified in relying on each such other opinion.

     (f) The Underwriters shall have received on the Closing Date an opinion of
  [ ], counsel for the Underwriters, dated the Closing Date, covering certain
  matters referred to in Section 6(c) above.

     The opinions of Cahill Gordon & Reindel, General Counsel of the Company,
and the Selling Stockholders' Counsels described in Sections 6(c), 6(d) and 6(e)
above (and any opinions of counsel for any Selling Stockholder referred to in
the immediately preceding paragraph) shall be rendered to the Underwriters at
the request of the Company or one or more of the Selling Stockholders, as the
case may be, and shall so state therein.

     (g) The Underwriters shall have received, on each of the date hereof and
  the Closing Date, a letter dated the date hereof or the Closing Date, as the
  case may be, in form and substance satisfactory to the Underwriters, from
  Arthur Andersen L.L.P., independent auditors, containing statements of
  information of the type ordinarily included in accountants' "comfort letters"
  to underwriters with respect to the financial statements and certain financial
  information contained in the Registration statement and the Final Prospectus;
  provided that the letter delivered on the Closing Date shall use a "cut-off
  date" not earlier than the date hereof.

     (h) The "lock-up" agreements, each substantially in the form of Exhibit A
  hereto, between you and certain stockholders, officers and directors of the
  Company relating to sales and certain other dispositions of shares of Common
  Stock or certain other securities, delivered to you on or before the date
  hereof, shall be in full force and effect on the Closing Date.

     The several obligations of the Underwriters to purchase Additional Shares
hereunder are subject to the delivery to you on the Option Closing Date of such
documents as you may reasonably request with respect to the good standing of the
Company, the due authorization and issuance of the Additional Shares and other
matters related to the issuance of the Additional Shares.

     7. Covenants of the Company. In further consideration of the agreements of
the Underwriters herein contained, the Company covenants with each Underwriter
as follows:

     (a) To furnish to you, without charge, signed copies of the Registration
  Statement (including exhibits thereto) and for delivery to each other
  Underwriter a conformed copy of the Registration Statement (without exhibits
  thereto) and to furnish to you in New York City, without charge, prior to
  10:00 a.m. New York city time on the business day next succeeding the date of
  this Agreement and during the period mentioned in Section 7(c) below, as many
  copies of the Final Prospectus and any supplements and amendments thereto or
  to the Registration Statement as you may reasonably request.

     (b) Before amending or supplementing the Registration Statement or the
  Final Prospectus, to furnish to you a copy of each such proposed amendment or
  supplement and not to file any such proposed amendment or supplement to which
  you reasonably object, and to file with the Commission within the applicable
  period specified in Rule 424(b) under the Act any prospectus required to be
  filed pursuant to such Rule.

     (c) If, during such period after the first date of the public offering of
  the Shares as in the opinion of counsel for the Underwriters the Final
  Prospectus is required by law to be delivered in connection with sales by an
  Underwriter or dealer, any event shall occur or condition exist as a result of
  which it is necessary to amend or supplement the Final Prospectus in order to
  make the statements therein, in the light of the circumstances when the Final
  Prospectus is delivered to a purchaser, not misleading, or if, in the opinion
  of counsel for the Underwriters, it is necessary to amend or supplement the
  Final Prospectus to comply with applicable law, forthwith to prepare, file
  with the Commission and furnish to the Underwriters and to the dealers (whose
  names and addresses you will furnish to the Company) to which Shares may have
  been sold by you on behalf of the Underwriters and to any other dealers upon
  request, either amendments or supplements to the Final Prospectus so that the
  statements in the Final Prospectus as so amended or supplemented will not, in
  the light of the circumstances when the FinalProspectus is delivered to a
  purchaser, be misleading or so that the Final Prospectus, as amended or
  supplemented, will comply with law. If, in accordance with the preced-

<PAGE>   28
                                      -27-


  ing sentence, it shall be necessary to amend or supplement the Final
  Prospectus at any time prior to the expiration of nine months after the first

     (e) To make generally available to the Company's security holders and to

<PAGE>   29
                                      -28-

other costs and expenses incident to the performance of the obligations of the
Company hereunder for which provision is not otherwise made in this Section 8.
It is understood, however, that except as provided in this Section 8, Section 9

below, the Underwriters will pay all of their costs and expenses, including fees
and disbursements of their counsel, stock transfer taxes payable on resale of
any of the Shares by them and any advertising expenses connected with any offers
they may make.

     The provisions of this Section shall not supersede or otherwise affect any
agreement that the Sellers may otherwise have for the allocation of such
expenses among themselves.

     9. Indemnity and Contribution.

     (a) The Company agrees to indemnity and hold harmless each Underwriter and
  each person, if any, who controls any Underwriter within the meaning of either
  Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
  against any and all losses, claims, damages and liabilities (including,
  without limitation, any reasonable legal or other expenses reasonably incurred
  in connection with defending or investigating any such action or claim) caused
  by any untrue statement or alleged untrue statement of a material fact
  contained in the Registration Statement or any amendment thereof, any
  Preliminary Final Prospectus or the Final Prospectus (as amended or
  supplemented if the Company shall have furnished any amendments or supplements
  thereto), or caused by any omission or alleged omission to state therein a
  material fact required to be stated therein or necessary to make the

<PAGE>   30
                                      -29-


  statements therein not misleading, except insofar as such losses, clams,
  damages or liabilities are caused by any such untrue statement or omission or
  alleged untrue statement or omission based upon information relating to any
  Underwriter furnished to the Company in writing by such Underwriter through
  you expressly for use therein.

     (b) Each Selling Stockholder agrees, severally and not jointly, to
  indemnity and hold harmless (i) the Company, its directors, its officers who
  sign the Registration Statement and each person, if any, who controls the
  Company within the meaning of either Section 15 of the Act or Section 20 of
  the Exchange Act and (ii) each Underwriter and each person, if any, who
  controls any Underwriter within the meaning of either Section 15 of the Act or
  Section 20 of the Exchange Act, from and against any and all losses, claims,
  damages and liabilities (including, without limitation, any reasonable legal
  or other expenses reasonably incurred in connection with defending or
  investigating any such action or claim) caused by any untrue statement or
  alleged untrue statement of a material fact contained in the Registration
  Statement or any amendment thereof, any Preliminary Final Prospectus or the
  Final Prospectus (as amended or supplemented if the Company shall have
  furnished any amendments or supplements thereto), or caused by any omission or
  alleged omission to state therein a material fact required to be stated
  therein or necessary to make the statements therein not misleading, but only
  with reference to information relating to such Selling Stockholder furnished
  in writing by or on behalf of such Selling Stockholder expressly for use in
  the Registration Statement, any Preliminary Final Prospectus, the Final
  Prospectus or any amendments or supplements thereto.

     (c) The Company agrees to indemnify and hold harmless each Selling
  Stockholder and each person, if any, who controls each Selling Stockholder
  within the meaning of either Section 15 of the Act or Section 20 of the
  Exchange Act, from and against any and all losses, claims, damages and
  liabilities (including, without limitation, any reasonable legal or other
  expenses reasonably incurred in connection with defending or investigating any
  such action or claim) caused by any untrue statement or alleged untrue
  statement of a material fact contained in the Registration Statement or any
  amendment thereof, any Preliminary Final Prospectus or the Final Prospectus
  (as amended or supplemented if the Company shall have furnished any amendments

<PAGE>   31
                                      -30-


  or supplements thereto), or caused by any omission or alleged omission to
  state therein a material fact required to be stated therein or necessary to
  make the statements therein not misleading, except insofar as such losses,
  claims, damages or liabilities are caused by any such untrue statement or
  omission or alleged untrue statement or omission based upon information
  relating to any Selling Stockholder furnished to the Company in writing by
  such Selling Stockholder or any information relating to any Underwriter
  furnished to the Company in writing by such Underwriter expressly for use
  therein.

     (d) Each Underwriter agrees, severally and not jointly, to indemnify and
  hold harmless the Company, the Selling Stockholders, the directors of the
  Company, the officers of the Company who sign the Registration Statement and
  each person, if any, who controls the Company or any Selling Stockholder
  within the meaning of either Section 15 of the Act or Section 20 of the
  Exchange Act from and against any and all losses, claims, damages and
  liabilities (including, without limitation, any reasonable legal or other
  expenses reasonably incurred in connection with defending or investigating any
  such action or claim) caused by any untrue statement or alleged untrue
  statement of a material fact contained in the Registration Statement or any
  amendment thereof, any Preliminary Final Prospectus or the Final Prospectus
  (as amended or supplemented if the Company shall have furnished any amendments
  or supplements thereto), or caused by any omission or alleged omission to
  state therein a material fact required to be stated therein or necessary to
  make the statements therein not misleading, but only with reference to
  information relating to such Underwriter furnished to the Company in writing
  by such Underwriter through you expressly for use in the Registration
  Statement, any Preliminary Final Prospectus, the Final Prospectus or any
  amendments or supplements thereto.

     (e) In case any proceeding (including any governmental investigation) shall
  be instituted involving any person in respect of which indemnity may be sought
  pursuant to Section 9(a), 9(b), 9(c) or 9(d), such person (the "INDEMNIFIED
  PARTY") shall promptly notify the person against whom such indemnity may be
  sought (the "INDEMNIFYING PARTY") in writing and the indemnifying party, upon
  request of the indemnified party, shall retain counsel reasonably satisfactory
  to the indemnified party to represent the indemnified party and any others the
  in-

<PAGE>   32
                                      -31-


  demnifying party may designate in such proceeding and shall pay the fees
  and disbursements of such counsel related to such proceeding. In any such
  proceeding, any indemnified party shall have the right to retain its own
  counsel, but the fees and expenses of such counsel shall be at the expense of
  such indemnified party unless (i) the indemnifying party and the indemnified
  party shall have mutually agreed to the retention of such counsel or (ii) the
  named parties to any such proceeding (including any impleaded parties) include
  both the indemnifying party and the indemnified party and representation of
  both parties by the same counsel would be inappropriate due to actual or
  potential differing interests between them. It is understood that the
  indemnifying party shall not, in respect of the legal expenses of any
  indemnified party in connection with any proceeding or related proceedings in
  the same jurisdiction, be liable for (i) the reasonable fees and expenses of
  more than one separate firm (in addition to any local counsel) for all
  Underwriters and all persons, if any, who control any Underwriter within the
  meaning of either Section 15 of the Act or Section 20 of the Exchange Act,
  (ii) the reasonable fees and expenses of more than one separate firm (in
  addition to any local counsel) for the Company, its directors, its officers
  who sign the Registration Statement and each person, if any, who controls the
  Company within the meaning of either such Section and (iii) the reasonable
  fees and expenses of more than one separate firm (in addition to any local
  counsel) for all Selling Stockholders and all persons, if any, who control any
  Selling Stockholder within the meaning of either such Section, and that all
  such fees and expenses shall be reimbursed as they are incurred. In the case
  of any such separate firm for the Underwriters and such control persons of any
  Underwriters, such firm shall be designated in writing by [Managing
  Underwriter]. In the case of any such separate firm for the Company, and such
  directors, officers and control persons of the Company, such firm shall be
  designated in writing by the Company. In the case of any such separate firm
  for the Selling Stockholders and such control persons of any Selling
  Stockholders, such firm shall be designated in writing by the Selling
  Stockholders holding a majority of the outstanding shares of Common Stock held
  by the Selling Stockholders considered as a group. The indemnifying party
  shall not be liable for any settlement of any proceeding effected without its
  written consent, but if settled with such consent or if there be a final
  judgment for the plaintiff, the indemnifying party agrees to indemnify the
  indemnified

<PAGE>   33
                                      -32-


  party from and against any loss or liability by reason of such settlement
  or judgment. No indemnifying party shall, without the prior written consent of
  the indemnified party, effect any settlement of any pending or threatened
  proceeding in respect of which any indemnified party is or could have been a
  party and indemnity could have been sought hereunder by such indemnified
  party, unless such settlement includes an unconditional release of such
  indemnified party from all liability on claims that are the subject matter of
  such proceeding.

     (f) To the extent the indemnification provided for in Section 9(a), 9(b),
  9(c) or 9(d) is unavailable to an indemnified party or insufficient in respect
  of any losses, claims, damages or liabilities referred to therein, then each
  indemnifying party under such paragraph, in lieu of indemnifying such
  indemnified party thereunder, shall contribute to the amount paid or payable
  by such indemnified party as a result of such losses, claims, damages or
  liabilities (i) in such proportion as is appropriate to reflect the relative
  benefits received by the indemnifying party or parties on the one hand and the
  indemnified party or parties on the other hand from the offering of the Shares
  or (ii) if the allocation provided by clause 9(f)(i) above is not permitted by
  applicable law, in such proportion as is appropriate to reflect not only the
  relative benefits referred to in clause 9(f)(i) above but also the relative
  fault of the indemnifying party or parties on the one hand and of the
  indemnified party or parties on the other hand in connection with the
  statements or omissions that resulted in such losses, claims, damages or
  liabilities, as well as any other relevant equitable considerations. The
  relative benefits received by the Sellers on the one hand and the Underwriters
  on the other hand in connection with the offering of the Shares shall be
  deemed to be in the same respective proportions as the net proceeds from the
  offering of the Shares (before deducting expenses) received by each Seller and
  the total underwriting discounts and commissions received by the Underwriters,
  in each case as set forth in the table on the cover of the Final Prospectus,
  bear to the aggregate Public Offering Price of the Shares. The relative fault
  of the Sellers on the one hand and the Underwriters on the other hand shall be
  determined by reference to among other things, whether the untrue or alleged
  untrue statement of a material fact or the omission or alleged omission to
  state a material fact relates to information supplied by the Company, the
  Selling Stock-

<PAGE>   34
                                      -33-


  holders or by the Underwriters and the parties' relative intent, knowledge,
  access to information and opportunity to correct or prevent such statement or
  omission. The Underwriters' respective obligations to contribute pursuant to
  this Section 9 are several in proportion to the respective number of Shares
  they have purchased hereunder, and not joint.

     (g) The Sellers and the Underwriters agree that it would not be just or
  equitable if contribution pursuant to this Section 9 were determined by pro
  rata allocation (even if the Underwriters were treated as one entity for such
  purpose) or by any other method of allocation that does not take account of
  the equitable considerations referred to in Section 9(f). The amount paid or
  payable by an indemnified party as a result of the losses, claims, damages and
  liabilities referred to in the immediately preceding paragraph shall be deemed
  to include, subject to the limitations set forth above, any legal or other
  expenses reasonably incurred by such indemnified party in connection with
  investigating or defending any such action or claim. Notwithstanding the
  provisions of this Section 9, no Underwriter shall be required to contribute
  any amount in excess of the amount by which the total price at which the
  Shares underwritten by it and distributed to the public were offered to the
  public exceeds the amount of any damages that such Underwriter has otherwise
  been required to pay by reason of such untrue or alleged untrue statement or
  omission or alleged omission. Notwithstanding the provisions of this Section
  9, no Selling Stockholder shall be required to indemnify or contribute any
  amount in excess of the net proceeds from the offering of the Shares (before
  deducting expenses) received by such Selling Stockholder, by reason of such
  untrue or alleged untrue statement or omission or alleged omission. No person
  guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
  the Act) shall be entitled to contribution from any person who was not guilty
  of such fraudulent misrepresentation. The remedies provided for in this
  Section 9 are not exclusive and shall not limit any rights or remedies which
  may otherwise be available to any indemnified party at law or in equity.

     (h) The indemnity and contribution provisions contained in this Section 9
  and the representations, warranties and other statements of the Company and
  the Selling Stockholders contained in this Agreement shall remain operative
  and in full force and effect regardless of (i) any

<PAGE>   35
                                      -34-


  termination of this Agreement, (ii) any investigation made by or on behalf
  of any Underwriter or any person controlling any Underwriter, any Selling
  Stockholder or any person controlling any Selling Stockholder, or the Company,
  its officers or directors or any person controlling the Company and(iii)
  acceptance of and payment for any of the Shares.

     10. Termination. This Agreement shall be subject to termination by notice
given by you to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited on or by, as the case may be, any of the New
York Stock Exchange or the National Association of Securities Dealers, Inc.,
(ii) trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities or (iv) there shall have occurred any
outbreak or escalation of hostilities or any change in financial markets or any
calamity or crisis that, in your judgment, is material and adverse and (b) in
the case of any of the events specified in clauses 10(a)(i) through 10(a)(iv),
such event, singly or together with any other such event, makes it, in your
judgment, impracticable to market the Shares on the terms and in the manner
contemplated in the Final Prospectus.

     11. Effectiveness; Defaulting Underwriters. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

     If, on the Closing Date or the Option Closing Date, as the case may be, any
one or more of the Underwriters shall fail or refuse to purchase Shares that it
has or they have agreed to purchase hereunder on such date, and the aggregate
number of Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of the Shares to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the number of Firm Shares set forth
opposite their respective names in Schedule II or Schedule III bears to the
aggregate number of Firm Shares set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as you may specify, to
purchase the Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase on such date; provided that in no event shall the
number of Shares that any Underwriter has

<PAGE>   36
                                      -35-


agreed to purchase pursuant to this Agreement be increased pursuant to this
Section 11 by an amount in excess of one-ninth of such number of Shares without
the written consent of such Underwriter. If, on the Closing Date, any
Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the
aggregate number of Firm Shares with respect to which such default occurs is
more than one-tenth of the aggregate number of Firm Shares to be purchased, and
arrangements satisfactory to you, the Company and the Selling Stockholders for
the purchase of such Firm Shares are not made within 36 hours after such
default, this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter, the Company or the Selling Stockholders. In any such
case either you or the relevant Sellers shall have the right to postpone the
Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and in the Prospectus or
in any other documents or arrangements may be effected. If, on the option
Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase
Additional Shares and the aggregate number of Additional Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of
Additional Shares to be purchased, the non-defaulting Underwriters shall have
the option to (i) terminate their obligation hereunder to purchase Additional
Shares or (ii) purchase not less than the number of Additional Shares that such
non-defaulting Underwriters would have been obligated to purchase in the absence
of such default. Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of any Seller to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason any Seller shall be unable to perform its obligations under this
Agreement, the Sellers will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the reasonable fees and disbursements of their
counsel) reasonably incurred by such Underwriters in connection with this
Agreement or the offering contemplated hereunder.

     12. Counterparts. This Agreement may be signed in two or more counterparts,
each of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument.

     13. Applicable Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York.

     14. Headings. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

[Underwriter]

Dear Ladies and Gentlemen:

     The undersigned understands that [Managing Underwriters] propose to enter
into an Underwriting Agreement (the "UNDERWRITING AGREEMENT") with Atlas Air,
Inc., a Delaware corporation (the "COMPANY") and certain stockholders of the
Company (the "SELLING STOCKHOLDERS") providing for the public offering (the
"PUBLIC OFFERING") by the several Underwriters, including (the "UNDERWRITERS")
of ___ shares (the "SHARES") of the common stock, par value ($0.01 per share, of
the Company (the "COMMON STOCK").

     To induce the Underwriters that may participate in the Public Offering to
continue their efforts in connection with the Public Offering, the undersigned
hereby agrees that, without the prior written consent of [Managing Underwriter]
on behalf of the Underwriters, it will not, during the period commencing on the
date hereof and ending 90 days after the date of the final U.S. and
International prospectuses relating to the Public Offering (the "Prospectuses"),
(1) offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock or (2) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of Common Stock, whether any such transaction
described in clause (1) or (2) above is to be settled by delivery of Common
Stock or such other securities, in cash or otherwise. The foregoing sentence
shall not apply to (a) the sale of any Shares to the Underwriters pursuant to
the Underwriting Agreement, (b) the issuance by the Company of the shares of
Common Stock upon the exercise of an option or 


                                      A-1
<PAGE>   43
warrant or the conversion of a security outstanding on the date of the
Prospectuses and which option, warrant or conversion feature is described in the
Prospectuses, (c) if applicable, the sale of any shares of Common Stock to the
Company or the purchase of any shares of Common Stock by the Company pursuant to
the Company's employee benefit plans or (d) transactions relating to shares of
Common Stock or other securities acquired in open market transactions after the
completion of the Public Offering. In addition, the undersigned agrees that,
without the prior written consent of [Managing Underwriter] on behalf of the
Underwriters, it will not, during the period commencing on the date hereof and
ending 90 days after the date of the Prospectuses, make any demand for, or
exercise any right with respect to, the registration of any shares of Common
Stock or any security convertible into or exercisable or exchangeable for Common
Stock which would cause the Company to file a registration statement with the
Securities and Exchange Commission prior to the expiration of such 90 day
period.

     Whether or not the Public Offering actually occurs depends on a number of
factors, including market conditions. Any Public Offering will only be made
pursuant to the Underwriting Agreement, the terms of which are subject to
negotiation between the Company, the Selling Stockholders and the Underwriters.

                                                     Very truly yours,

Ladies and Gentlemen:

                  Atlas Air, Inc., a Delaware corporation (the "Company"),
hereby confirms its agreement with you (the "Underwriters"), as set forth below.

                  1. The Securities. Subject to the terms and conditions herein
contained, the Company proposes to issue and sell to the Underwriters (the

                  The Company has filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 and a related
preliminary prospectus for the registration of the Securities under the
Securities Act of 1933, as amended (the "Act"), and has filed such amendments
thereto, if any, as may have been required prior to the date hereof. Such
registration statement, as amended at the date of the Agreement, meets the
requirements set forth in Rule 415(a)(1)(x) under the Act and complies in all
other material respects with said rule.

                  As used in this Agreement, the term "Registration Statement"

declared effective, including any 462(b) Registration Statement (as defined) and

under the Rules and Regulations (as defined), if applica-

ble, and included in the Prospectus (as defined); the term "Preliminary
Prospectus" means each prospectus relating to the Securities filed with such
registration statement or any amendment thereto (including the prospectus, if
any, included in such registration statement or any amendment thereto at the
time it was or is declared effective; and the term "Prospectus" means the
prospectus relating to the Securities filed with the Registration Statement with
the Commission pursuant to Rule 430A and Rule 424(b) ("Rule 424(b)") under the
Rules and Regulations, if required, or, if no prospectus is required to be filed
pursuant to Rule 430A or Rule 424(b), such term means the prospectus included in
such Registration Statement. All references in this Agreement to the
Registration Statement, Preliminary Prospectus and Prospectus and to financial
statements and schedules and other information that is "contained," "included,"
"set forth," "described in" or "stated" therein (and all other references of
like import) shall be deemed to mean and include all such financial statements
and schedules and other information that is or is deemed to be incorporated by
reference therein; and all references in this Agreement to amendments or
supplements to the Registration Statement, the Preliminary Prospectus or the
Prospectus shall be deemed to mean and include the filing of any document under
the Securities Exchange Act of 1934, as amended (the "1934 Act"), that is or is
deemed to be incorporated by reference therein.

2. Representations and Warranties of the Company. The Company represents and
warrants to, and agrees with, each Underwriter that:

                  (a) A registration statement on Form S-3 has been filed with
         the Commission with respect to the Securities (File No.  ), including
         the form of prospectus, together with all amendments thereto, and has
         been prepared by the Company in conformity in all material respects
         with the requirements of the Act and the rules and regulations (the
         "Rules and Regulations") of the Commission thereunder and the Company
         meets all the requirements for filing on Form S-3. The Registration
         Statement at the time it was or will be declared effective and at the
         Closing Date (as defined) complies and will comply in all material
         respects with the requirements of the Act and the Rules and
         Regulations.

                  (b) The Commission has not issued any order preventing or
         suspending the use of any Preliminary Prospectus nor instituted any
         proceeding for such purpose. When any Preliminary Prospectus was filed
         with the Commission it
<PAGE>   4
                                      -4-

         (x) complied in all material respects with the requirements of the Act
         and (y) did not include any untrue statement of a material fact or omit
         to state any material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading. When the Registration Statement or any amendment
         thereto was or is declared effective and on the Closing Date, it did
         not and will not contain any untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading. The
         Prospectus, and any amendments or supplements thereto on the date first
         filed with the Commission pursuant to Rule 424(b) (or if not so filed,
         on the date the Registration Statement or the amendment thereto
         containing the Prospectus or amendment or supplement to the Prospectus
         was or is declared effective) and on the Closing Date, (i) complied and
         will comply in all material respects with the requirements of the Act
         and the Rules and Regulations and (ii) did not and will not contain any
         untrue statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading. The foregoing provisions of this paragraph (b) do not
         apply to statements or omissions in the Registration Statement or any
         amendment thereto or the Prospectus or any amendment or supplement
         thereto made in reliance upon and in conformity with written
         information with respect to the Underwriters furnished to the Company
         by [managing Underwriter] specifically for use therein.

                  The foregoing provisions of this paragraph (b) do not apply to
         statements or omissions made in any Preliminary Prospectus, the
         Registration Statement or any amendment thereto or the Prospectus or
         any amendment or supplement thereto in reliance upon and in conformity
         with written information furnished to the Company by the Underwriters
         specifically for use therein or to the Statement of Eligibility and
         Qualification (the "Form T-1") under the Trust Indenture Act of 1939,
         as amended (the "Trust Indenture Act"), of the Trustee filed as
         exhibits to the Registration Statement.

                  (c) The documents incorporated or deemed to be incorporated by
         reference in the Prospectus, at the time they were or hereafter are
         filed with the Commission, complied and will comply in all material
         respects with the
<PAGE>   5
                                      -5-

         requirements of the 1934 Act and the rules and regulations (the "1934
         Act Regulations") of the Commission thereunder, and when read together
         with the other information in the Prospectus, at the time the
         Registration Statement and any amendments thereto became or becomes
         effective and at the Closing Date, did not and will not contain an
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading.

                  (d) The Company has been duly incorporated, is validly
         existing as a corporation in good standing under the laws of the
         jurisdiction of its incorporation, has the corporate power and
         authority to own its property and to conduct its business as described
         in the Prospectus and to perform its obligations under this Agreement,
         the Indenture, and the Notes; the Company is duly qualified to transact
         business and is in good standing in each jurisdiction in which the
         conduct of its business or its ownership or leasing of property
         requires such qualification, except to the extent that the failure to
         be so qualified or be in good standing would not have a material
         adverse effect on the Company and its subsidiaries, taken as a whole (a
         "Material Adverse Effect").

                  (e) The Company's only subsidiaries are Atlas One, Inc., Atlas
         Freighter Leasing, Inc., Atlas Freighter Leasing II, Inc., Atlas Air
         Services Limited, LHC Properties, Inc., Atlas Flightlease, Inc. and
         Genessee Insurance Company, Ltd. (collectively, the "Subsidiaries").
         Each Subsidiary is a corporation duly organized, validly existing and
         in good standing under the laws of the jurisdiction of its
         incorporation with corporate power and authority under such laws to
         own, lease and operate its properties and conduct its business; and
         each Subsidiary is duly qualified to transact business as a foreign
         corporation and is in good standing in each other jurisdiction in which
         it owns or leases property of a nature, or transacts business of a
         type, that would make such qualification necessary, except to the
         extent that the failure to so qualify or be in good standing would not
         have a Material Adverse Effect. All of the outstanding shares of
         capital stock of each Subsidiary have been duly authorized and validly
         issued and are fully paid and non-assessable and are owned by the
         Company free and clear of any pledge, lien, security interest, charge,
         claim, equity or encumbrance of any kind.

                                      -6-

                  (f) The Company has all requisite corporate power and
         authority to execute, deliver, and perform each of its obligations
         under the Notes. The Notes have been duly and validly authorized by the
         Company for issuance and conform in all material respects to the
         description thereof in the Prospectus. The Notes, when executed by the
         Company and authenticated by the Trustee in accordance with the
         provisions of the Indenture, and delivered to and paid for by the
         Underwriters in accordance with the terms hereof, will have been duly
         executed, issued and delivered and will constitute valid and legally
         binding obligations of the Company, except that the enforcement thereof
         may be subject to (i) bankruptcy, insolvency, reorganization,
         moratorium or other similar laws now or hereafter in effect relating to
         creditors' rights generally, (ii) general principles of equity and the
         discretion of the court before which any proceeding therefor may be
         brought (regardless of whether such enforcement is considered in a
         proceeding in equity or at law), (iii) the unenforceability, under
         certain circumstances, of provisions imposing penalties, forfeitures,
         late payment charges or an increase in interest rate upon delinquency
         in payment or the occurrence of a default, and (iv) the
         unenforceability of any provision requiring the payment of attorneys'
         fees, except to the extent that a court determines such fees to be
         reasonable (each of clauses (i), (ii), (iii), and (iv), an
         "Enforceability Limitation").

                  (g) The Company has all requisite corporate power and
         authority to execute, deliver and perform its obligations under the
         Indenture. The Indenture has been duly authorized by the Company and,
         when executed and delivered by the Company (assuming the due
         authorization, execution and delivery thereof by the Trustee), will
         constitute a valid and legally binding agreement of the Company,
         enforceable against the Company in accordance with its terms, except
         that the enforcement thereof may be subject to the Enforceability
         Limitations. The Indenture has been qualified under the Trust Indenture
         Act and complies as to form in all material respects with the
         requirements of the Trust Indenture Act.

                  (h) The Company is a "citizen of the United States" (as
         defined in Section 40102(a)(15) of Title 49 of the United States Code,
         as amended) and is an air carrier operating under a certificate issued
         by the Secretary of Transportation pursuant to Chapter 447 of Title 49,
         United States Code, for aircraft capable of carrying 10 or more
<PAGE>   7
                                      -7-

         individuals or 6,000 pounds or more of cargo. There is in force with
         respect to the Company an air carrier operating certificate issued
         pursuant to Part 121 of the regulations under the sections of Title 49,
         United States Code, relating to aviation (the "Federal Aviation Act").
         All of the outstanding shares of capital stock of the Company have been
         duly authorized and validly issued and are fully paid and
         non-assessable.

                  (i) There has not occurred any material adverse change in the
         condition, financial or otherwise, or in the earnings, business or
         operations of the Company and the Subsidiaries, taken as a whole, from
         that set forth in the Prospectus.

                  (j) The Securities conform in all material respects to the
         description thereof contained in the Prospectus under the heading
         "Description of Debt Securities."

                  (k) The consolidated financial statements included or
         incorporated by reference in the Prospectus present fairly the
         consolidated financial position of the Company and its consolidated
         subsidiaries as of the dates indicated and the consolidated results of
         operations and cash flows or changes in financial position of the
         Company and its consolidated subsidiaries for the periods specified.
         Such financial statements have been prepared in conformity with
         generally accepted accounting principles applied on a consistent basis
         throughout the periods involved.

                  (l) The Company and the Subsidiaries possess adequate
         certificates, authorities and permits issued by appropriate
         governmental agencies or bodies necessary to conduct, in all material
         respects, the business now operated by them and have not received any
         notice of proceedings relating to the revocation or modification of any
         such certificate, authority or permit that would, individually or in
         the aggregate, have a Material Adverse Effect.

                  (m) The statistical and market-related data included in the
         Prospectus are based on or derived from sources that the Company and
         the Subsidiaries believe to be reliable and accurate.

                  (n) Except as accurately described in all material respects in
         the Prospectus and except as would not have a Material Adverse Effect
         and would not materially and ad-

         versely affect the ability of the Company to perform its obligations
         under this Agreement, the Notes, and the Indenture, or to consummate
         the transactions contemplated by the Prospectus, there are no legal or
         governmental proceedings pending or, to the best knowledge of the
         Company, threatened to which the Company or any of the Subsidiaries is
         or may be a party or to which any of the properties of the Company or
         any of the Subsidiaries is or may be subject.

                  (o) Except as described in the Prospectus, no consent,
         approval, authorization or order of any court or governmental agency or
         body is required for the performance of this Agreement, the Notes or
         the Indenture, by the Company or its Subsidiaries, except such as have
         been obtained or are contemplated to be obtained by the Prospectus and
         such as may be required under the Act, the Trust Indenture Act or state
         securities or "Blue Sky" laws in connection with the purchase and
         distribution of the Notes by the Underwriters. Each of the Company and
         the Subsidiaries has complied with all laws, regulations and orders
         applicable to it or its business, except for any violation of such
         laws, regulation or orders which would not have a Material Adverse
         Effect. Each of the Company and the Subsidiaries has performed in all
         material respects all of the obligations required to be performed by
         it, and is not in default under any indenture, mortgage, deed of trust,
         voting trust agreement, loan agreement, letter of credit agreement,
         bond, debenture, note agreement or other evidence of indebtedness,
         lease, contract or other agreement or instrument to which it is a party
         or by which it or any of its property is bound (collectively, the
         "Contracts"), except for such failures to perform or defaults as would
         not have a Material Adverse Effect, and, to the knowledge of the
         Company, no other party under any such Contracts is in material default
         in any respect thereunder, except for such defaults as would not have a
         Material Adverse Effect.

                  (p) The Company has all requisite corporate power and
         authority to execute, deliver and perform its obligations under this
         Agreement and to consummate the transactions contemplated hereby. This
         Agreement and the consummation by the Company of the transactions
         contemplated hereby have been duly authorized by the Company. This
         Agreement has been duly executed and delivered by the Company; no
         consent, approval, authorization or order of any court or governmental
         agency or body is required for the consummation by the Company of the
         transactions on its
<PAGE>   9
                                      -9-

         part herein contemplated, except such as may have been obtained under
         the Act or otherwise and such as may be required under state securities
         or "Blue Sky" laws; the performance of this Agreement and the
         consummation of the transactions contemplated hereby will not conflict
         with or result in a breach or violation of any of the terms and
         provisions of or constitute a default under the Certificate of
         Incorporation or By-laws of the Company. Except, in each case, for
         instances that would not result in a Material Adverse Effect or a
         material adverse effect on the ability of the Company to perform its
         obligations under this Agreement; the performance of this Agreement and
         consummation of the transactions contemplated hereby will not conflict
         with or result in a breach or violation of any of the terms and
         provisions of or constitute a default under or result in the creation
         or imposition of any lien, charge, or encumbrance upon the assets or
         properties of the Company or any Subsidiary, pursuant to any Contract
         statute, order, rule or regulation applicable to the Company or any
         Subsidiary or their respective businesses or properties or of any court
         or other governmental body.

                  (q) Each of the Company and the Subsidiaries has good and
         marketable title to all properties and assets described in the
         Prospectus as owned by it, free and clear of all liens, charges,
         encumbrances or restrictions, except such as are described in or
         referred to in the Prospectus or as would not have a Material Adverse
         Effect.

                  (r) The Company is not, and after giving effect to the
         transactions contemplated hereby or the Notes Offering (as defined)
         will not be, an "investment company" as such term is defined in the
         Investment Company Act of 1940 as amended.

                  (s) None of the Company, the Subsidiaries or an agent acting
         on their behalf has taken or will take any action that might cause this
         Agreement or the sale of the Securities to violate Regulation T, U or X
         of the Board of Governors of the Federal Reserve System.

                  (t) Except as described in the Prospectus, no labor problem
         exists with the Company's employees or with employees of any Subsidiary
         or, to the best knowledge of the Company, is imminent that could
         reasonably be expected to have a Material Adverse Effect, and the
         Company is not aware of any existing or imminent labor disturbance by
         the employees of any of its or any subsidiary's principal con-
<PAGE>   10
                                      -10-

         tractors or customers that could reasonably be expected to have a
         Material Adverse Effect.

                  (u) The Company and the Subsidiaries (A) are in compliance
         with any and all applicable foreign, federal, state and local laws and
         regulations relating to the protection of human health and safety, the
         environment or hazardous or toxic substances or wastes, pollutants or
         contaminants ("Environmental Laws"), (B) have received all permits,
         licenses or other approvals required of them under applicable
         Environmental Laws to conduct their respective businesses and (C) are
         in compliance with all terms and conditions of any such permit, license
         or approval, except where such noncompliance with Environmental Laws,
         failure to receive required permits, licenses or other approvals or
         failure to comply with the terms and conditions of such permits,
         licenses or approvals would not, singly or in the aggregate, have a
         Material Adverse Effect.

                  (v) Each of the Company and the Subsidiaries carries insurance
         in such amounts and covering such risks as it deems reasonable for the
         conduct of its business and the value of its properties.

                  3. Purchase, Sale and Delivery of the Securities. On the basis
of the representations, warranties, agreements and covenants herein contained
and subject to the terms and conditions herein set forth, the Company agrees to
issue and sell to the Underwriters, and each of the Underwriters severally
agrees to purchase from the Company, at [ ] of their principal amount, the
respective aggregate principal amounts of the Notes set forth opposite their
respective names on Schedule 1 hereto. The obligations of the Underwriters under
this Agreement are several and not joint. One or more certificates in definitive
form for the Notes that the Underwriters have agreed to purchase hereunder, and
in such denomination or denominations and registered in such name or names as
each Underwriter requests upon notice to the Company at least two business days
prior to the Closing Date, shall be delivered by or on behalf of the Company,

therefor (less an amount equivalent to payment of interest at the then
applicable Federal Funds Rate on the purchase price of the Securities for one
(1) day) by wire transfer or check of immediately available funds to the account
of the Company previously designated by it in writing. Such delivery of and
payment for the Securities shall be made at the offices of [ ] at 10:00 a.m.

<PAGE>   11
                                      -11-

time or date as the Underwriters and the Company may agree upon or as the
Underwriters may determine pursuant to Section 7(a) hereof, such time and date
of delivery against payment being herein referred to as the "Closing Date." The
Company will make such certificate or certificates for the Notes available for
checking and packaging by the Underwriters at the offices in New York, New York
of [ ] at least 24 hours prior to the Closing Date.

                  4. Offering by the Underwriters. After the Prospectus has been
filed pursuant to rule 424(b) promulgated under the Act, the Underwriters
propose to offer for sale to the public the Securities at the price and upon the
terms set forth in the Prospectus relating to the Securities.

                  5. Covenants of the Company. The Company covenants and agrees
with the Underwriters that:

                  (a) If required, the Company will file the Prospectus and any
         amendments or supplements thereto with the Commission in the manner and
         within the time period required by Rule 424(b) (but only if the
         Underwriters or their counsel have not reasonably objected thereto
         promptly after having been furnished a copy thereof a reasonable time
         prior to the proposed filing thereof). During any time when a
         prospectus relating to the Securities is required to be delivered under
         the Act, the Company (i) will comply with all requirements imposed upon
         it by the Act and the Rules and Regulations to the extent necessary to
         permit the continuation of sales of or dealings in the Securities in
         accordance with the provisions hereof and of the Prospectus, as then
         amended or supplemented, and (ii) will not file with the Commission the
         Prospectus or the amendment referred to in the second sentence of
         Section 2(a) hereof or any amendment or supplement to such Prospectus
         or any amendment to the Registration Statement of which the
         Underwriters and their counsel shall not previously have been advised
         and furnished a copy for a reasonable period of time prior to the
         proposed filing and as to which filing the Underwriters and their
         counsel shall not have given their respective consent, which consent
         will not be unreasonably withheld or delayed. The Company will prepare
         and will file with the Commission, in accordance with the Act and the
         Rules and Regulations, promptly upon request by the Underwriters or
         counsel for the Underwriters, any amendments to the Registration
         Statement or amendments or supplements to the Prospectus that may be
         necessary or reasonably advisable in connection with the
<PAGE>   12
                                      -12-

         distribution of the Securities by the Underwriters, and the Company
         will use its reasonable best efforts to cause any such amendment to the
         Registration Statement to be declared effective by the Commission
         promptly. The Company will advise the Underwriters, promptly after it
         receives notice thereof, of the time when the Registration Statement or
         any amendment thereto has been filed or declared effective or the
         Prospectus or any amendments or supplements thereto have been filed.

                  (b) The Company will advise the Underwriters, promptly after
         receiving notice or obtaining knowledge thereof, of (i) the issuance by
         the Commission of any stop order suspending the effectiveness of the
         Registration Statement or any amendment thereto or any order preventing
         or suspending the use of any Preliminary Prospectus or the Prospectus,
         or any amendments or supplements thereto, (ii) the suspension of the
         qualification of the Securities for offering or sale in any
         jurisdiction, (iii) the institution, threat or contemplation of any
         proceeding for any such purpose or (iv) any request made by the
         Commission for amending the Registration Statement, for amending or
         supplementing the Prospectus or for additional information. The Company
         will use its reasonable best efforts to prevent the issuance of any
         such stop order and, if any such stop order is issued, to obtain the
         withdrawal thereof as promptly as possible.

                  (c) The Company will cooperate with the Underwriters in
         arranging for the qualification of the Securities for offering and sale
         under the securities or "Blue Sky" laws of such jurisdictions in the
         United States and Canada as the Underwriters may designate and will
         continue such qualifications in effect for as long as may be necessary
         to complete the distribution of the Securities; provided that in
         connection therewith the Company shall not be required to qualify as a
         foreign corporation or to execute a general consent to service of
         process in any jurisdiction or to subject itself to taxation in respect
         of doing business in any jurisdiction in which it is not otherwise
         subject.

                  (d) During such time as a prospectus relating to the
         Securities is required to be delivered under the Act, if after due
         inquiry, the Company should become aware of any event that occurs, and
         as a result of which the Prospectus as then amended or supplemented
         would include any untrue statement of a material fact, or omit to state
         a material
<PAGE>   13
                                      -13-

         fact required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, or if the Company should be of the opinion that for any
         other reason it is necessary at any time to amend or supplement the
         Prospectus to comply with the Act or the Rules and Regulations, the
         Company will promptly notify the Underwriters and their counsel thereof
         and the Company will prepare and, subject to Section 5(a) hereof, will
         file with the Commission, at its sole expense, an amendment to the
         Registration Statement or an amendment or supplement to the Prospectus
         (in form and substance reasonably satisfactory to the Underwriters and
         their counsel and in compliance with the Act and the Rules and
         Regulations) so that the Prospectus as so supplemented or amended will
         not contain an untrue statement of material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading, or so that the Prospectus will comply with
         law, and will deliver to the Underwriters, without charge, such number
         of copies thereof as they may reasonably request.

                  (e) The Company will, without charge, provide (i) to the
         Underwriters and to their counsel a signed copy of the registration
         statement originally filed and each amendment thereto (in each case
         including exhibits thereto) and the Registration Statement and (ii) so
         long as a prospectus relating to the Securities is required to be
         delivered under the Act, as many copies of each Preliminary Prospectus
         and the Prospectus relating to the Securities and any amendment or
         supplement thereto as each Underwriter may reasonably request.

                  (f) The Company, as soon as practicable but not later than 90
         days after the close of the period covered thereby, will make generally
         available to holders of the Securities and to the Underwriters
         consolidated earning statements of the Company (which need not be
         certified by an independent public accountant) that satisfy the
         provisions of Section 11(a) of the Act and Rule 158 thereunder covering
         a twelve-month period ending [ ].

                  (g) For and during the period ending [five] years after the
         effective date of the Registration Statement, the Company will furnish
         to the Underwriters copies of all reports and other communications
         (financial or otherwise) furnished by the Company to its
         securityholders generally
<PAGE>   14
                                      -14-

         and copies of any reports or financial statements furnished to or filed
         by the Company with the Commission or any national securities exchange
         on which any class of securities of the Company may be listed.

                  (h) Prior to the Closing Date, the Company will furnish to the
         Underwriters, as soon as they have been prepared and are available, a
         copy of any unaudited interim consolidated financial statements of the
         Company and any pro forma information prepared in respect of any period
         subsequent to the period covered by its most recent financial
         statements included in the Registration Statement and the Prospectus.

                  (i) The Company will not at any time, directly or indirectly,
         take any action designed, or that might reasonably be expected, to
         cause or result in, or that will constitute, stabilization or
         manipulation of the price of the Notes to facilitate the sale or resale
         of any of the Securities in violation of the 1934 Act.

                  (j) The Company will apply the net proceeds from the sale of
         the Securities as set forth in the Prospectus.

                  6. Expenses. The Company agrees to pay all costs and expenses
incident to the performance of its obligations under this Agreement, whether or
not the transactions contemplated herein are consummated or this Agreement is
terminated, as provided in this Section 6 including all costs and expenses
incident to (i) the printing or other production of documents with respect to
the transactions, including any costs of printing the registration statement
originally filed with respect to the Securities and any amendment thereto and
the Registration Statement, any Preliminary Prospectus and the Prospectus and
any amendment or supplement thereto, (ii) the printing (or reproduction) and
delivery of this Agreement, the Securities, any Blue Sky Memoranda and all other
documents and agreements printed (or reproduced) and delivered in connection
with the offering of the Securities, (iii) all arrangements relating to the
delivery to the Underwriters of copies of the foregoing documents, (iv) the fees
and disbursements of the counsel, the accountants and any other experts or
advisors retained by the Company or its subsidiaries, (v) preparation (including

                                      -15-

fees of the Commission and the [New York Stock Exchange, Inc.] relating to the
Securities, (viii) expenses of the Company and its subsidiaries in connection

                  If the sale of the Securities provided for herein is not
consummated because any condition to the obligations of the Underwriters set
forth in Section 7 hereof is not satisfied, because this Agreement is terminated
pursuant to Section 10 hereof or because of any failure, refusal or inability on
the part of the Company to perform all obligations and satisfy all conditions on
its part to be performed or satisfied hereunder (other than solely by reason of
a default by the Underwriters of their obligations hereunder after all
conditions hereunder have been satisfied in accordance herewith), the Company
will promptly reimburse the Underwriters upon demand for all reasonable
out-of-pocket expenses (including reasonable fees and disbursements of counsel
for the Underwriters) that shall have been incurred by the Underwriters in
connection with the proposed purchase and sale of the Securities not so
delivered.

                  7. Conditions of the Underwriters' Obligations. The obligation

shall be subject to the following additional conditions:

                  (a) No stop order suspending the effectiveness of the
         Registration Statement or any amendment thereto or the qualification of
         the Indenture under the Trust Indenture Act shall have been issued and

         issued, fully paid and nonassessable.

                  (iv) The Company is not an "investment company" as defined in

<PAGE>   17
                                      -17-

         Statement or the Prospectus).

                  (vii) The descriptions in the Registration Statement and
         Prospectus of contracts and other documents are accurate in all
         material respects and fairly present the information required to be

         and will not conflict with or result in a breach of any of the terms or
         provisions of or violate or constitute a default under, the Certificate
         of Incorporation or By-laws of the Company, or, except, in each case,
         for instances that would not result in a Material Adverse Effect or a
         material adverse effect on the ability of the Company to perform its
         obligations under this Agreement, any material indenture or mortgage

         to such counsel to which the Company is a party or by which the Company
         or its properties is bound, or any existing federal or New York state
         statute, rule or regulation, or any judgment, order or decree known to
         such counsel, of any government, governmental instrumentality or
         Federal or New York State court, domestic or foreign, having

         jurisdiction over the Company or any of its properties.

                  Such counsel has participated in the preparation of the
Registration Statement and Prospectus. Although such counsel is not passing upon
and does not assume any responsibility for the accuracy, completeness or
fairness of the statements contained in the Registration Statement and
Prospectus on the basis of the foregoing (relying as to materiality to a large
extent on discussions with, and representations and opinions of officers and
other representatives of the Company), no facts have come to the attention of
such counsel to lead him to believe (A) that the Registration Statement or any
amendment thereto (except for the financial statements and other financial or
statistical data included therein or omitted therefrom, as to which such counsel
need express no opinion), at the time the Registration Statement or any such
amendment became effective, contained or contains an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading or (B) that the
Prospectus or any amendment or supplement thereto (except for the financial
statements and other financial or statistical data included therein or omitted
therefrom, as to which such counsel need express no opinion), at the time the
Prospectus was issued, at the time any such amended or supplemented prospectus
was issued or at the Closing Date, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                  In rendering the foregoing opinions, Such counsel may (i)
state that their opinion is limited to matters governed by the federal laws of
the United States of America, the laws of the State of [ ] and (ii) rely, to the
extent such counsel deems proper, upon the representations set forth herein and
on certificates of public officials and officers of the Company, with respect to
the accuracy of factual matters contained therein which were not independently
established.

                  (c) The Underwriters shall have received an opinion of
_______, General Counsel for the Company, dated as of the Closing Date, in form
and substance satisfactory to the Underwriters, to the effect that:

                  (i) The Company is duly qualified to transact business as a
         foreign corporation and is in good standing in each other jurisdiction
         in the United States in which it owns or leases property of a nature,
         or transacts business of a type, that would make such qualification
         necessary, except to the extent that the failure to so qualify or be in
         good standing would not have a Material Adverse Effect on the Company
         and its Subsidiaries, considered as one enterprise.

                  (ii) Each Subsidiary is a corporation duly organized under the
         laws of its jurisdiction of incorporation and is duly qualified to
         transact business as a foreign corporation and is in good standing in
         each other jurisdiction in which it owns or leases property of a
         nature, or transacts business of a type, that would make such
         qualification necessary, except to the extent that the failure to so
         qualify or be in good standing would not have a Material Adverse Effect
         on the Company and its Subsidiaries, considered as one enterprise.

                  (iii) Such counsel does not know of any statutes or
         regulations, or any pending or threatened legal or governmental
         proceedings, required to be described in the Prospectus that are not
         described as required, nor of any contracts or documents of a character
         required to be described or referred to in the Registration Statement
         or the Prospectus or to be filed as exhibits to the Registration
         Statement that are not described, referred to or filed as required.

                  (iv) All of the issued and outstanding shares of the capital
         stock of each Subsidiary are validly issued, fully paid and
         nonassessable and, to such counsel's knowledge, all of the issued and
         outstanding shares of stock of each Subsidiary are owned by the Company
         free and clear of all mortgages, pledges, liens, security interests,
         conditional sales agreements, charges and encumbrances of every nature.

                  (v) The Company possesses all state and federal
         authorizations, approvals, consents and licenses necessary for the
         operations of its business except for such authorizations, approvals,

         Material Adverse Affect.

                  (vi) The Company is an "air carrier" and a "citizen of the
         United States" within the meaning of Section 40102(a)(15) of Title 49
         of the United States Code, as amended, holding an air carrier operating
         certificate issued by the Secretary of Transportation pursuant to
         Chapter 447 of Title 49 of the United States Code, as amended, for
         aircraft capable of carrying 10 or more individuals or 6,000 pounds or
         more of cargo.

                  (vii) To the knowledge of such counsel, except as disclosed in
         the Prospectus, there is no event of default under any material
         agreement or instrument under which indebtedness of the Company is
         outstanding or by which it is bound or any of its properties is
         subject.

                  Such counsel has participated in the preparation of the
Registration Statement and Prospectus. Although such counsel is not passing upon
and does not assume any responsibility for the accuracy, completeness or
fairness of the statements contained in the Registration Statement and
Prospectus, on the basis of the foregoing (relying as to materiality to a large
extent on discussions with, and representations and opinions of officers and
other representatives of the Company), no facts have come to the attention of
such counsel to lead him to believe (A) that the Registration Statement or any
amendment thereto (except for the financial statements and other financial or
statistical data included therein or omitted therefrom, as to which such counsel
need express no opinion), at the time the Registration Statement or any such
amendment became effective, contained or contains an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading or (B) that the
Prospectus or any amendment or supplement thereto (except for the financial
statements and other financial or statistical data included therein or omitted
therefrom, as to which such counsel need express no opinion), at the time the
Prospectus was issued, at the time any such amended or supplemented prospectus
was issued or at the Closing Date, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

stock or long-term indebtedness of the Company and its Subsidiaries that is
material to the Company and the Subsidiaries, taken as a whole.

         Agreement are true and correct in all material respects as if made on
         and as of the Closing Date, and the Company has performed in all

                  (ii) No stop order suspending the effectiveness of the

                  8. Indemnification and Contribution.

                  (a) The Company and each of the Subsidiaries, jointly and
severally, agrees to indemnify and hold harmless each Underwriter, and each
person, if any, who controls any Underwriter within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act, against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter or such controlling
person may become subject under the Act, the Exchange Act or otherwise, insofar
as any such losses, claims,
<PAGE>   24
                                      -24-

damages or liabilities (or actions in respect thereof) arise out of or are based
upon:

                  (i) any untrue statement or alleged untrue statement of any
         material fact contained in (A) the Registration Statement or any
         amendment thereto or any Preliminary Prospectus or the Prospectus or
         any amendments or supplements thereto or (B) any application or other
         document, or any amendment or supplement thereto, executed by the
         Company or based upon written information furnished by or on behalf of
         the Company filed in any jurisdiction in order to qualify the
         Securities under the securities or "Blue Sky" laws thereof or filed
         with the Commission or any securities association or securities
         exchange (each an "Application"); or

                  (ii) the omission or alleged omission to state in such
         Registration Statement or any amendment thereto, any Preliminary
         Prospectus or the Prospectus or any amendment or supplement thereto, or
         any Application, a material fact required to be stated therein or
         necessary to make the statements therein not misleading,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any reasonable legal or other out-of-pocket expenses reasonably
incurred by any such Underwriter or any such controlling person in connection
with investigating or defending against or appearing as a third-party witness in
connection with any such loss, claim, damage, liability or action in respect
thereof; provided that the Company will not be liable in any such case to the
extent, but only to the extent, that any such loss, claim, damage, or liability
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in such Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any
amendments or supplements thereto, or any Application in reliance upon and in
conformity with written information furnished to the Company by the Underwriters
through the Underwriters with respect to the Underwriters specifically for use
therein; provided, further, that the Company and each of the Subsidiaries will
not be liable to any Underwriter if such untrue statement or omission or alleged
untrue statement or omission was contained or made in any Preliminary Prospectus
and completely corrected in the Prospectus and any such loss, liability, claim,
damage or expense suffered or incurred by any Underwriter resulted from any
action, claim or suit by any person who purchased Securities that are the
subject thereof from any Underwriter and such Underwriter failed to deliver or
pro-
<PAGE>   25
                                      -25-

vide a copy of the Prospectus relating to the Securities to such person with or
prior to the confirmation of the sale of such Securities sold to such person in
any case where delivery is required by the Act or the Rules and Regulations,
unless such failure to deliver or provide a copy of the Prospectus relating to
the Securities was a result of noncompliance by the Company with Section
5(e)(ii) of this Agreement. This indemnity agreement will be in addition to any
liability that the Company and each of the Subsidiaries may otherwise have to
the indemnified parties. The Company and each of the Subsidiaries shall not be
liable under this Section 8 for any settlement of any claim or action effected
without its prior written consent, which shall not be unreasonably withheld. The
Underwriters shall not, without the prior written consent of the Company, effect
any settlement or compromise of any pending or threatened proceeding in respect
of which the Company is or could have been a party, or indemnity could have been
sought hereunder by the Company, unless such settlement (A) includes an
unconditional written release of the Company, in form and substance reasonably
satisfactory to the Company, from all such liability on claims that are the
subject matter of such proceeding and (B) does not include any statement as to
an admission of fault, culpability or failure to act by or on behalf of the
Company.

                  (b) Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors and each of its officers who signed
the Registration Statement and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
against any losses, claims, damages or liabilities to which the Company, or any
such director, officer or controlling person may become subject under the Act,
the Exchange Act, or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement or any amendment thereto, any Preliminary
Prospectus or the Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged omission to state therein a
material fact required to be stated in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto, or any Application, or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through the Underwriters
specifically for use therein; and, subject to the
<PAGE>   26
                                      -26-

limitation set forth immediately preceding this clause, will reimburse, as
incurred, any legal or other expenses incurred by the Company or any such
director, officer or controlling person in connection with investigating or
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action in respect thereof. This indemnity
agreement will be in addition to any liability that the Underwriters may
otherwise have to the indemnified parties. No Underwriter shall be liable under
this Section 8 for any settlement of any claim or action effected without its
prior written consent, which shall not be unreasonably withheld. The Company
shall not, without the prior written consent of the applicable Underwriter,
effect any settlement or compromise of any pending or threatened proceeding in
respect of which such Underwriter is or could have been a party, or indemnity
could have been sought hereunder by such Underwriter, unless such settlement (A)
includes an unconditional written release of such Underwriter, in form and
substance reasonably satisfactory to such Underwriter, from all such liability
on claims that are the subject matter of such proceeding and (B) does not
include any statement as to an admission of fault, culpability or failure to act
by or on behalf of such Underwriter.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action for which such indemnified
party is entitled to indemnification under this Section 8, such indemnified
party will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party of the commencement
thereof, but the omission so to notify the indemnifying party (i) will not
relieve it from any liability under paragraph (a) or (b) above unless and to the
extent such failure results in the forfeiture by the indemnifying party of
substantial rights and defenses and (ii) will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligations provided in paragraphs (a) and (b) above. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party;
provided that if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have been
advised by counsel that there may be one or more legal defenses available to it
and/or other indemnified parties that are different from or additional to those
available to the indemni-
<PAGE>   27
                                      -27-

fying party, then the indemnifying party shall not have the right to direct the
defense of such action on behalf of such indemnified party or parties and such
indemnified party or parties shall have the right to select separate counsel to
defend such action on behalf of such indemnified party or parties. After notice
from the indemnifying party to such indemnified party of its election so to
assume the defense thereof and approval by such indemnified party of counsel
appointed to defend such action, the indemnifying party will not be liable to
such indemnified party under this Section 8 for any legal or other expenses,
other than reasonable costs of investigation, subsequently incurred by such
indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the immediately preceding sentence (it being understood, however,
that in connection with such action the indemnifying party shall not be liable
for the expenses of more than one separate counsel (in addition to local
counsel) in any one action or separate but substantially similar actions in the
same jurisdiction arising out of the same general allegations or circumstances,
designated by any Underwriter in the case of paragraph (a) of this Section 8 or
the Company, in the case of paragraph (b) of this Section 8, representing the
indemnified parties under such paragraph (a) or paragraph (b), as the case may
be, who are parties to such action or actions), (ii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party or (iii) the indemnifying party shall have failed to
assume the defense or retain counsel reasonably satisfactory to the indemnified
party. After such notice from the indemnifying party to such indemnified party,
the indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the consent
of the indemnifying party, which consent shall not be unreasonably withheld.

                  (d) In circumstances in which the indemnity agreement provided
for in the preceding paragraphs of this Section 8 is for any reason unavailable
or insufficient to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the offering of the Securities or (ii) if
the allocation provided by the foregoing clause (i)
<PAGE>   28
                                      -28-

is not permitted by applicable law, not only such relative benefits but also the
relative fault of the indemnifying party or parties on the one hand and the
indemnified party on the other in connection with the statements or omissions or
alleged statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof). The relative benefits received by
the Company on the one hand and the Underwriters on the other shall be deemed to
be in the same proportion as (x) the total proceeds from the offering (net of
underwriter's discounts and commissions but before deducting expenses) received
by the Company and (y) the total underwriting discounts and commissions received
by the Underwriters, respectively, in each case as set forth in the table on the
cover page of the Prospectus. The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by an indemnified party or
parties on the one hand, or the indemnifying party or parties on the other, the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission, and any other equitable
considerations appropriate in the circumstances. The Company and the
Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Company on the one hand and the Underwriters on the other hand were treated as
one entity for such purpose) or by any other method of allocation that does not
take into account the equitable considerations referred to in the first sentence
of this paragraph (d). Notwithstanding any other provision of this paragraph
(d), no Underwriter shall be obligated to make contributions hereunder that in
the aggregate exceed the total underwriting discounts and commissions received
by such Underwriter under this Agreement, less the aggregate amount of any
damages that such Underwriter has otherwise paid or been required to pay by
reason of the untrue or alleged untrue statements or the omissions or alleged
omissions to state a material fact, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this paragraph (d), each person, if any, who
controls an Underwriter within the meaning of Section 15 of the Act or Section
20 of the Exchange Act shall have the same rights to contribution as such
Underwriter, and each director of the Company, and each officer of the Company
who signed the Registration Statement and each person, if any, who controls the
Company within the meaning of Section 15 of the 
<PAGE>   29
                                      -29-

Act or Section 20 of the Exchange Act, shall have the same rights to
contribution as the Company.

                  9. Survival Clause. The respective representations,
warranties, agreements, covenants, indemnities and other statements of the
Company, the Company's officers, and the Underwriters set forth in this
Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement shall remain in full force and effect, regardless of (i) any
investigation made by or on behalf of the Company or any of its officers or
directors, the Underwriters or any controlling person referred to in Section 8
hereof and (ii) delivery of and payment for the Securities. The respective
agreements, covenants, indemnities and other statements set forth in Sections 6
and 8 hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement.

                  10. Termination.

                  (a) This Agreement may be terminated in the sole discretion of
the Underwriters by notice to the Company, given prior to the Closing Date, in
the event that the Company shall have failed, refused or become unable to
perform all obligations and satisfy all conditions on its part to be performed
or satisfied hereunder at or prior thereto or, if at or prior to the Closing
Date:

                  (i) trading in securities generally on the New York Stock
         Exchange, Inc., the American Stock Exchange or the Nasdaq Stock Market
         shall have been suspended or minimum or maximum prices shall have been
         established on any such exchange;

                  (ii) a banking moratorium shall have been declared by New York
         or United States authorities; or

                  (iii) there shall have been (A) an outbreak or escalation of
         hostilities between the United States and any foreign power, (B) an
         outbreak or escalation of any other insurrection or armed conflict
         involving the United States or any other national or international
         calamity or emergency or (C) any material change in the financial
         markets of the United States which, in the sole judgment of the
         Underwriters, makes it impracticable or inadvisable to proceed with the
         public offering or the delivery of the Securities as contemplated by
         the Registration Statement, as amended as of the date hereof.

                  (b) Termination of this Agreement pursuant to this Section 10
shall be without liability of any party to any other party except as provided in
Section 9 hereof.

                  11. Increase in Underwriters' Commitments. If any Underwriter
shall default in its obligation to take up and pay for the Securities to be
purchased by it hereunder on the Closing Date and if the amount of Securities
that all Underwriters so defaulting shall have agreed but failed to take up and
pay for does not exceed 10% of the total number of Securities that the
Underwriters are obligated to purchase on the Closing Date, the non-defaulting
Underwriters shall take up and pay for (in addition to the Securities they are
obligated to purchase pursuant to Section 1 hereof) the number of Securities
agreed to be purchased by all such defaulting Underwriters on the Closing Date,
as hereinafter provided. Such Securities shall be taken up and paid for by such
non-defaulting Underwriter or Underwriters in such amount or amounts as you may
designate with the consent of each Underwriter so designated or, in the event no
such designation is made, such Securities shall be taken up and paid for by all
non-defaulting Underwriters pro rata in proportion to the aggregate amount of
Securities set opposite the names of such non-defaulting Underwriters in
Schedule I.

                  If a new allocation is made in accordance with the foregoing
provision, you shall have the right to postpone the Closing Date, as the case
may be, for a period not exceeding five business days in order that any
necessary changes in the Registration Statement and Prospectus and other
documents may be effected.

                  The term Underwriter as used in this agreement shall refer to
and include any Underwriter substituted under this Section 11 with like effect
as if such substituted Underwriter had originally been named in Schedule I.

                  If the amount of Securities that all Underwriters so
defaulting shall have agreed but failed to take up and pay for exceeds 10% of
the total number of Securities that the Underwriters are obligated to purchase
on the Closing Date, this Agreement shall terminate without liability on the
part of any non-defaulting Underwriter.

                  12. Information Supplied by the Underwriters

                  The statements set forth in the last paragraph on the front

the Company for the purposes of Sections 2(b), 8(a) and 8(b) hereof. Each
Underwriter confirms that such statements, to the extent such statements relate

and be binding upon the Underwriters and the Company and their respective
successors and legal Underwriters, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal
or equitable right, remedy or claim under or in respect of this Agreement, or

provisions hereof are intended to be and are for the sole and exclusive benefit
of such persons and for the benefit of no other person except that (i) the

20 of the Exchange Act. No purchaser of Securities from the Underwriters will be

                  15. APPLICABLE LAW. THE VALIDITY AND INTERPRETATION OF THIS
AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY

                                 ATLAS AIR, INC.

                            Pass Through Certificates

                             Underwriting Agreement
                               Standard Provisions

                                                                   Date

     From time to time, Atlas Air, Inc., a Delaware corporation (the "Company"),
may enter into one or more underwriting agreements (each, an "Underwriting
Agreement") that provide for the sale of Designated Certificates (as defined
below) to the several underwriters named therein. Each Underwriting Agreement
will consist of a pricing agreement substantially in the form of Annex I hereto,
which may incorporate by reference the standard provisions set forth herein and
include such additions and deletions as the parties thereto may determine (the
"Pricing Agreement"). For any Underwriting Agreement, the term "Underwriters"
means the firms named in Schedule I to the applicable Pricing Agreement, and the
term "Representatives" means the firms designated in the Pricing Agreement as
the Representatives of the Underwriters in connection with such Underwriting
Agreement. The term "Representatives" also refers to a single firm acting as
sole representative of the Underwriters and to Underwriters who act without any
firm being designated as their representative.

     1. Sale of Pass Through Certificates. The Company proposes that from time
to time Wilmington Trust Company as Pass Through Trustee or another Pass Through
Trustee identified in a Pricing Agreement (the "Pass Through Trustee"), pursuant
to the Pass Through Agreement, as supplemented by a supplement thereto (each, a
"Series Supplement") between the Company and the Pass Through Trustee (such Pass
Through Agreement, as supplemented by each Series Supplement relating to the
Designated Certificates (as defined below) being herein referred to as the "Pass
Through Agreement"), issue Pass Through Certificates ("Pass Through
Certificates") and, subject to the terms and conditions set forth in the
applicable Underwriting Agreement, sell to the several Underwriters therefor the
Pass Through Certificates specified in Schedule II to the related Pricing
Agreement (the "Designated Certificates"). Each series of Designated
Certificates will represent interests in a separate trust (each, a "Trust")
established pursuant to the Pass Through Agreement to fund the purchase of notes
(with respect to any series of Des-

                                      -2-


ignated Certificates, the "Equipment Notes") issued (a) on a nonrecourse basis
by one or more owner trustees pursuant to separate leveraged lease transactions
(such Equipment Notes, the "Leased Aircraft Notes") to finance or refinance a
portion of the equipment cost of aircraft, including engines (each, a "Leased
Aircraft" and, collectively, the "Leased Aircraft"), which have been or will be
leased to the Company pursuant to a separate lease agreement (each such lease
agreement, a "Lease") for each Leased Aircraft, or (b) by, and with recourse to,
the Company (such Equipment Notes, the "Owned Aircraft Notes") either to finance
or refinance all or a portion of the equipment cost of, or to purchase all or a
portion of the outstanding debt with respect to, aircraft, including engines
(each, an "Owned Aircraft" and, collectively, the "Owned Aircraft"; together
with Leased Aircraft, the "Aircraft"), which have been or will be purchased and
owned by the Company. In the case of either Leased Aircraft Notes or Owned
Aircraft Notes, such financing or refinancing is referred to herein as a
"Financing" or "Refinancing", respectively. In connection with each series of
Equipment Notes, the Company will enter into a separate note purchase agreement
(each a "Note Purchase Agreement") in the form given to the Representatives
prior to execution of the relevant Pricing Agreement. Each series of Leased
Aircraft Notes will be issued under a Trust Indenture and Security Agreement
between Wilmington Trust Company, as indenture trustee, or another indenture
trustee identified in a Pricing Agreement (the "Loan Trustee"), and the Owner
Trustee (the "Leased Aircraft Indenture"), the form of which has been given to
the Representatives. Each series of Owned Aircraft Notes will be issued under a
Trust Indenture and Security Agreement between Wilmington Trust Company, as
indenture trustee, or another indenture trustee identified in a Pricing
Agreement, as Loan Trustee, and the Company (the "Owned Aircraft Indenture" and
together with the Leased Aircraft Indenture, the "Indentures"). Capitalized
terms used but not otherwise defined herein shall have the meaning, with respect
to each series of Pass Through Certificates as to which such reference relates,
specified in or pursuant to the Indenture or Note Purchase Agreement relating to
each related series of Equipment Notes.

     Each Pricing Agreement shall specify the aggregate face amount of the
Designated Certificates covered thereby, the initial public offering price of
such Designated Certificates, the purchase price to the Underwriters of such
Designated Certificates, the compensation payable to the Underwriters with
respect to such Designated Certificates, the names of the Underwriters of such
Designated Certificates, the names of the Rep-

<PAGE>   3
                                      -3-


resentatives of such Underwriters and the face amount of such Designated
Certificates to be purchased by each Underwriter and shall set forth the date,
time and manner of delivery of such Designated Certificates and payment
therefor. The Pricing Agreement shall also specify certain terms and rights of
such Designated Certificates, and may specify additional representations,
warranties, agreements and conditions applicable to the sale of such Designated
Certificates. A Pricing Agreement shall be in the form of an executed writing
(which may be in counterparts), and may be evidenced by an exchange of
telegraphic communications or any other rapid transmission device designed to
produce a written record of communications transmitted. For each Underwriting
Agreement, the obligations of the related Underwriters shall be several and not
joint.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (File No. 333-_____ the
"Initial Registration Statement") relating to certain equity securities, debt
securities and pass through certificates, including the Designated Certificates,
and the offering thereof from time to time in accordance with Rule 415 under the
Securities Act of 1933, as amended (the "Act"). The Company has filed with, or
transmitted for filing to, or shall within some period of time hereafter file
with or transmit for filing to, the Commission a prospectus supplement (the
"Prospectus Supplement") specifically relating to the Designated Certificates
pursuant to Rule 424 under the Act.

     The term "Preliminary Prospectus" means any preliminary prospectus included
in the Initial Registration Statement or filed with the Commission pursuant to
Rule 424(a) of the rules and regulations of the Commission under the Act. The
term "Registration Statement" means the various parts of the Initial
Registration Statement, including all exhibits thereto and including (i) the
information contained in the form of final prospectus filed with the Commission
pursuant to Rule 424(b) under the Act in accordance with Section 5(a) hereof and
deemed by virtue of Rule 430A under the Act to be part of the registration
statement at the time it was declared effective and (ii) the documents
incorporated by reference in the prospectus contained in the Initial
Registration Statement at the time such part of the registration statement
became effective but excluding Form T-1, each as amended at the time such part
of the registration statement became effective or such part of a registration
statement increasing the size of the offering filed pursuant to Rule 462(b)
under the Act (a "Rule 462(b) Registration Statement"), if any, became or
hereafter becomes effective, such final prospectus in form first filed pursuant

<PAGE>   4
                                      -4-


to Rule 424(b) under the Act, being hereafter called the "Prospectus"; any
reference herein to any preliminary Prospectus or the Prospectus shall be deemed
to refer to and include documents incorporated by reference therein pursuant to
Item 12 of Form S-3 under the Act, as of the date of such Preliminary Prospectus
or Prospectus, as the case may be; any reference to any amendment or supplement
to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and
include any documents filed after the date of such Preliminary Prospectus or
Prospectus, as the case may be, under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and incorporated by reference in such Preliminary
Prospectus or the Prospectus, as the case may be; any reference to any amendment
to the Registration Statement shall be deemed to refer to and include any annual
report of the Company filed pursuant to Section 13(a) or 15(d) of the Exchange
Act after the effective date of the Registration Statement that is incorporated
by reference in the Registration Statement; and any reference to the Prospectus
as amended or supplemented shall be deemed to refer to the Prospectus as amended
or supplemented in relation to the applicable Designated Certificates in the
form in which it is filed with the Commission pursuant to Rule 424(b) under the
Act in accordance with Section 5(a) hereof, including any documents incorporated
by reference therein as of the date of such filing. The term "Pass Through
Documents" with respect to any Designated Certificates means the Underwriting
Agreement, the Pass Through Agreement, each Note Document (as defined in the
Pass Through Agreement), any Participation Agreement relating to the Equipment
Notes underlying such Designated Certificates, and each other agreement or
document referred to in the relevant Pricing Agreement. The term "Company PTC
Documents" with respect to any Designated Certificates means the Pass Through
Documents relating to such Designated Certificates to which the Company is or is
intended to be a party.

     2. Representations and Warranties. For any Underwriting Agreement and the
related Designated Certificates the Company represents and warrants to, and
agrees with, each Underwriter therefor that:

          (a) The Company meets the requirements for use of Form S-3 under the
     Act for purposes of the registration under the Act of the Pass Through
     Certificates; the Company is the "issuer" within the meaning of the Act and
     appropriate registrant with respect to the Pass Through Certificates. The
     Initial Registration Statement and any post-effective amendment thereto,
     each in the form heretofore delivered to the Representatives

<PAGE>   5
                                      -5-


     and, excluding exhibits to the Initial Registration Statement, but
     including all documents incorporated by reference in the prospectus
     contained therein, to the Representatives for each of the other
     Underwriters, has been declared effective by the Commission in such form,
     other than a Rule 462(b) Registration Statement, if any, which became
     effective upon filing; no other document with respect to the Initial
     Registration Statement or document incorporated by reference therein has
     heretofore been filed or transmitted for filing with the Commission; no
     stop order suspending the effectiveness of the Initial Registration
     Statement has been issued and no proceeding for that purpose has been
     initiated or, to the Company's knowledge, threatened by the Commission;

          (b) The documents incorporated by reference in the Prospectus, when
     they became effective or were filed with the Commission, as the case may
     be, conformed in all material respects to the requirements of the Act or
     the Exchange Act, as applicable, and the rules and regulations of the
     Commission thereunder, and none of such documents contained an untrue
     statement of a material fact or omitted to state a material fact necessary
     to make the statements therein, in light of the circumstances under which
     they were made, not misleading; and any further documents so filed and
     incorporated by reference in the Prospectus, when such documents become
     effective or are filed with the Commission, as the case may be, will
     conform in all material respects to the requirements of the Act or the
     Exchange Act, as applicable, and the rules and regulations of the
     Commission thereunder and will not contain an untrue statement of a
     material fact or omit to state a material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by or on behalf of any Representative expressly for use in the Prospectus
     as amended or supplemented relating to such Designated Certificates;

          (c) The Registration Statement and the Prospectus conform, and any
     further amendments or supplements to the Registration Statement or the
     Prospectus will conform, in all material respects to the requirements of

<PAGE>   6
                                      -6-


     the Act and the rules and regulations of the Commission thereunder and do
     not and will not, as of the applicable effective date as to the
     Registration Statement and any amendment thereto and as of the applicable
     filing date and Time of Delivery (as defined below) as to the Prospectus
     and any amendment or supplement thereto, contain an untrue statement of a
     material fact or omit to state a material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by or on behalf of any Representative with respect to the Designated
     Certificates expressly for use in the Prospectus as amended or supplemented
     relating to such Designated Certificates; on the effective date of the
     Registration Statement the form of the Pass Through Agreement filed as an
     exhibit to the Registration Statement did comply in all material respects
     with the requirements of the Trust Indenture Act of 1939, as amended (the
     "Trust Indenture Act") and the rules thereunder, and as of the Time of
     Delivery the Pass Through Agreement will comply in all material respects
     with the requirements of the Trust Indenture Act and the rules thereunder;

          (d) Since the date of the latest financial statements included or
     incorporated by reference in the Prospectus, there has not occurred any
     material adverse change, or any development involving a prospective
     material adverse change, in the condition, financial or otherwise, or in
     the earnings, business or operations of the Company and its subsidiaries,
     taken as a whole, from that set forth in the Prospectus;

          (e) The Company has been duly organized, validly existing as a
     corporation in good standing under the laws of the jurisdiction of its
     incorporation, has the corporate power, and authority to own its property
     and conduct its business as described in the Prospectus and to perform its
     obligations under each such Company PTC Document to which it is, or is to
     be, a party; the Company is duly qualified to transact business and is in
     good standing in each jurisdiction in which the conduct of its business or
     its ownership or leasing of property requires such qualification, except to
     the extent that the failure to be so qualified or be in good standing

<PAGE>   7
                                      -7-


     would not have a material adverse effect on the Company and its
     subsidiaries, taken as a whole (an "Atlas Material Adverse Effect");

          (f) The Company is a "citizen of the United States" (as defined in
     Section 40102(a)(15) of Title 49 of the United States Code, as amended and
     is an air carrier operating under a certificate issued by the Secretary of
     Transportation pursuant to Chapter 447 of Title 49 of the United States
     Code, for aircraft capable of carrying 10 or more individuals or 6,600
     pounds or more of cargo. There is in force with respect to the Company an
     air carrier operating certificate issued pursuant to Part 121 of the
     regulations under sections of Title 49, United Stated Code (the "Federal
     Aviation Act").

          (g) The Company PTC Documents relating to such Designated Certificates
     to which the Company is, or is to be, a party, have each been duly
     authorized by the Company, do not require any stockholder approval, or
     approval or consent of any trustee or holder of any indebtedness or
     obligations of the Company, and do not and will not contravene any law,
     judgment, governmental rule, regulation, order or decree currently in
     effect or in effect at the time of execution and delivery of such document
     and applicable to the Company or any of its subsidiaries or the certificate
     of incorporation or by-laws of the Company or any of its subsidiaries or
     contravene or result in a breach of any of the terms or the provisions of,
     or constitute a default under, or result in the creation of any Lien (other
     than as permitted under each Lease and each Owned Aircraft Indenture
     relating to a series of Equipment Notes) upon the property of the Company
     under any indenture, mortgage, bank credit agreement, note or bond purchase
     agreement, long-term lease, license or other agreement or instrument to
     which the Company or any of its subsidiaries is a party or by which it or
     any of its subsidiaries may be bound or affected, which contravention,
     breach or default would have an Atlas Material Adverse Effect;

          (h) Neither the valid authorization, execution and delivery by the
     Company of the Company PTC Documents relating to such Designated
     Certificates in accordance with the provisions thereof, nor the
     consummation by the Company of any of the transactions contemplated
     thereby, requires the consent or approval of,

<PAGE>   8
                                      -8-

     Representatives may reasonably request, and, if the delivery of a
     prospectus is required at any time in connection with the offering or sale
     of such Designated Certificates and if at such time any event shall have
     occurred as a result of which the Prospectus as then amended or
     supplemented would include an untrue statement of a material fact or omit
     to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made when
     such Prospectus is delivered, not misleading, or, if for any other reason
     it shall be necessary during such same period to amend or supplement the
     Prospectus or to file under the Exchange Act any document incorporated by

     Act or the Trust Indenture Act, to notify the Representatives and upon
     their request to file such document and to prepare and furnish without
     charge to each Underwriter and to any dealer in securities (it being
     understood that each such Underwriter and dealer shall, at the Company's
     request, be specified by the Representatives to the Company) as many copies
     as the Representatives may from time to time reasonably request of an
     amended Prospectus or a supplement to the Prospectus which will correct
     such statement or omission or effect such compliance; and in case the
     Representatives or any of the Underwriters or any dealer in securities is
     required to deliver a prospectus in connection with sales of any Designated
     Certificates at any time nine months or more after the time of issue of the
     Prospectus as amended or supplemented relating to such Designated
     Certificates, then upon the request of the Representatives, but at the
     expense of the Representatives, the relevant Underwriters or the relevant
     dealers in securities, as the case may be, the Company shall prepare

<PAGE>   14
                                      -14-

     or supplemented prospectus complying with Section 10(a)(3) of the Act;

          (d) To make generally available to its security holders as soon as

     date of the Registration Statement (as defined in Rule 158(c)), an earning
     statement of the Company and its subsidiaries (which need not be audited)
     complying with Section 11(a) of the Act and the rules and regulations of
     the Commission thereunder (including at the option of the Company Rule
     158); (e) If the Company elects to rely upon Rule 462(b), the Company shall
     file a Rule 462(b) Registration Statement with the Commission in compliance

     earlier of (i) the termination of trading restrictions for such Designated
     Certificates, as notified to the Company by the Representatives, and (ii)
     the Time of Delivery for such Designated Certificates, not to offer, sell,
     contract to sell or otherwise dispose of any public debt securities
     registered under the Act or any debt securities which may be sold in a
     transaction exempt from the registration requirements of the Act in
     reliance on Rule 144A under the Act and which are marketed through the use
     of a disclosure document containing substantially the same information as a
     prospectus for similar debt securities registered under the Act without the
     prior written consent of the Representatives, which consent shall not be
     unreasonably withheld.

     In addition, the Company agrees with each Underwriter of Designated
Certificates that, if the purchase of any Equipment Notes is delayed pursuant to
a Postponement Notice (as defined

<PAGE>   15
                                      -15-


in the Pass Through Agreement) then, prior to any such purchase all conditions
specified in any related Participation Agreement, Note Purchase Agreement or
Pass Through Agreement to be performed or satisfied at or prior to such purchase
shall have been performed or satisfied; and the Company will provide (or cause
to be provided) to the Representatives executed copies of all documents
delivered under such Participation Agreement, Note Purchase Agreement or Pass
Through Agreement and of each opinion to be delivered pursuant to such
Participation Agreement (other than any opinion delivered to an Owner

Underwriting Agreement relating to such Designated Certificates are, at and as

          Delivery with the same effect as if made at the Time of Delivery and

          or incorporated by reference in the Prospectus, there has been no
          material adverse change in the financial condition or operations of
          the Company and its subsidiaries, taken as a whole, whether or not
          arising from transactions in the ordinary course of business, except
          as set forth in or contemplated in the Prospectus as amended or
          supplemented;

          (c) On the date of the Pricing Agreement for such Designated
     Certificates and at the Time of Delivery for the Designated Certificates,

     audited the financial statements of the Company and its subsidiaries

     the Commission containing financial statements and incorporated by
     reference in the Registration Statement, if the date of such report is
     later than such effective date, and a letter dated such Time of Delivery,
     respectively, to the effect set forth in Annex II hereto, and with respect

     cates, there shall not have been (i) any change or decrease specified in
     the letter or letters referred to in paragraph (c) of this Section 6 or
     (ii) any change, or any development involving a prospective change, in or
     affecting the business or properties of the Company and its subsidiaries,
     taken as a whole, the effect of which, in any case referred to in clause
     (i) or (ii) above, is, in the reasonable judgment of the Representatives,
     so material and adverse as to make it impractical or inadvisable to proceed
     with the public offering or the delivery of the Designated Certificates as
     contemplated by the Prospectus as amended or supplemented;

          (e) Subsequent to the time of execution of the Pricing Agreement
     relating to the Designated Certificates (i) there shall not have been any

     Notes, any opinion delivered to the Owner Participant relating to solely
     tax matters), addressed to the Representatives on behalf of the
     Underwriters or accompanied by a letter from counsel rendering such opinion
     authorizing the Underwriters to rely on such opinion as if it were
     addressed to them; provided, however, that this condition (f) need not be
     satisfied prior to the Time of Delivery with respect to conditions
     specified in any such Note Purchase Agreement or Participation

<PAGE>   19
                                      -19-


     Agreement under which the purchase of the Equipment Notes contemplated
     thereby is delayed until after the Time of Delivery pursuant to a
     Postponement Notice to the Pass Through Trustee pursuant thereto;

          (g) Prior to the Time of Delivery, the Company shall have furnished to
     the Representatives such further information, certificates and documents as
     the Representatives may reasonably request; and

          (h) The Company shall have complied with the provisions of Section
     5(c) hereof with respect to the furnishing of prospectuses on the New York
     Business Day next succeeding the date of the Pricing Agreement.

     All such opinions, certificates, letters and documents shall be deemed to
be in compliance with the provisions hereof only if they are in all material
respects reasonably satisfactory to the Representatives and counsel to the
Underwriters; provided, however, to the extent that any of the matters set forth
in the opinions annexed as Exhibits A, B or C hereto shall be separately covered
in substantially the same form in legal opinions of the relevant legal counsel
addressed to the Representatives and delivered at the Time of Delivery in
connection with the Note Purchase Agreement or Participation Agreements, such
other legal opinions shall be deemed to satisfy the foregoing requirements to
the extent of the matters covered.

     For any Underwriting Agreement, if any condition specified in this Section
shall not have been fulfilled in all material respects when and as required to
be fulfilled, other than by reason of any default by any Underwriter, such
failure to fulfill a condition may be waived by the Representatives, or such
Underwriting Agreement may be terminated by the Representatives by written
notice to the Company at, or at any time prior to, the Time of Delivery for the
related Designated Certificates. Notice of such termination shall be given to
the Company in writing or by oral communication or telegraph confirmed in
writing.

     7. Payment of Expenses. For any Underwriting Agreement, the Company will
pay the reasonable costs incident to the authorization, issuance, sale and
delivery of the Designated Certificates to be sold to the Underwriters and any
taxes payable in that connection; the reasonable costs (other than fees and

     8. Indemnification and Contribution. For any Underwriting Agreement:

          (a) The Company agrees to indemnify and hold harmless each Underwriter
     and each person who controls any Underwriter within the meaning of either
     the Act or the Exchange Act against any and all losses, claims, damages or
     liabilities, joint or several, to which they or any of them may become
     subject under the Act, the Exchange Act or other Federal or state statutory
     law or regulation, at common law or otherwise, insofar as such losses,
     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based upon any untrue statement or alleged untrue statement of a
     mate-

<PAGE>   21
                                      -21-


     rial fact contained in the Registration Statement or in any amendment
     thereof, or in any Preliminary Prospectus, preliminary prospectus
     supplement relating to the Designated Certificates or the Prospectus, or in
     any amendment thereof or supplement thereto, or in any other prospectus
     relating to the Pass Through Certificates, or arise out of or are based
     upon the omission or alleged omission to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, and agrees to reimburse each such indemnified party, as
     incurred, for any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such loss, claim, damage,
     liability or action; provided, however, that (i) the Company will not be
     liable in any such case to the extent that any such loss, claim, damage or
     liability arises out of or is based upon any such untrue statement or
     alleged untrue statement or omission or alleged omission made therein in
     reliance upon and in conformity with written information furnished to the
     Company by or on behalf of the Representatives specifically for use
     therein, (ii) such indemnity with respect to any Preliminary Prospectus
     shall not inure to the benefit of any Underwriter (or any person
     controlling such Underwriter) as to whom it shall be established did not
     send or deliver to the person asserting any such loss, claim, damage or
     liability and who purchased the Designated Certificates which are the
     subject thereof a copy of the Prospectus as amended or supplemented
     excluding documents incorporated therein by reference at or prior to the
     written confirmation of the sale of such Designated Certificates to such
     person in any case where such delivery is required by the Act and the
     untrue statement or omission of a material fact contained in such
     Preliminary Prospectus was corrected in the Prospectus as amended or
     supplemented and (iii) the Company will not be Liable for any such loss,
     claim, damage or liability in connection with any settlement of any pending
     or threatened litigation or any pending or threatened governmental agency
     investigation or proceeding if that settlement is effected without the
     prior written consent of the Company, which consent shall not be
     unreasonably withheld. This indemnity agreement will be in addition to any
     liability which the Company may otherwise have.

<PAGE>   22
                                      -22-


          (b) Each Underwriter severally agrees to indemnify and hold harmless
     the Company, each of its directors, each of its officers who signs the
     Registration Statement, and each person who controls the Company within the
     meaning of either the Act or the Exchange Act, to the same extent as the
     foregoing indemnity from the Company to each Underwriter and agrees to
     reimburse each such indemnified party, as incurred, for any legal or other
     expenses reasonably incurred by them in connection with investigating or
     defending any loss, claim, damage, liability or action, but only with
     reference to written information furnished to the Company by or on behalf
     of any Underwriter specifically for inclusion in the Registration
     Statement, any Preliminary Prospectus, any preliminary prospectus
     supplement relating to the Designated Certificates, the Prospectus, or in
     any amendment thereof or supplement thereto, or any other prospectus
     relating to the Designated Certificates. This indemnity agreement will be
     in addition to any liability which any Underwriter may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
     8 of notice of the commencement of any action or proceeding (including any
     governmental investigation), such indemnified party will, if a claim for
     indemnification in respect thereof is to be made against the indemnifying
     party under Section 8 (a) or (b) hereof, notify the indemnifying party in
     writing of the commencement thereof; but the omission so to notify the
     indemnifying party will not relieve it from any Liability which it may have
     to such indemnified party otherwise than under this Section 8 (a) or (b)
     hereof, and then only to the extent that the indemnifying party is
     prejudiced thereby. In case any such action or proceeding is brought
     against any indemnified party, and it notifies the indemnifying party of
     the commencement thereof, the indemnifying party will be entitled to
     participate therein (jointly with any other indemnifying party similarly
     notified), and to the extent that it may elect, by written notice,
     delivered to such indemnified party promptly after receiving the aforesaid
     notice from such indemnified party, to assume the defense thereof, with
     counsel reasonably satisfactory to such indemnified party; provided,
     however, that if the defendants in any such action include both the
     indemnified party and the indemnifying party and the indemnified party
     shall have reasonably concluded that

<PAGE>   23
                                      -23-


     there may be legal defenses available to it and/or other indemnified
     parties which are different from or additional to those available to the
     indemnifying party, the indemnified party or parties shall have the right
     to select separate counsel to defend such action on behalf of such
     indemnified party or parties. Upon receipt of notice from the indemnifying
     party to such indemnified party of its election so to appoint counsel to
     defend such action and approval by the indemnified party of such counsel,
     the indemnifying party will not be liable to such indemnified party under
     this Section 8 for any legal or other expenses subsequently incurred by
     such indemnified party in connection with the defense thereof unless (i)
     the indemnified party shall have employed separate counsel in accordance
     with the proviso to the next preceding sentence (it being understood,
     however, that the indemnifying party shall not be liable for the expenses
     of more than one separate counsel, approved by the Underwriters in the case
     of paragraph (a) of this Section 8, representing the indemnified parties
     under such paragraph (a) who are parties to such action), (ii) the
     indemnifying party shall not have employed counsel reasonably satisfactory
     to the indemnified party to represent the indemnified party within a
     reasonable time after notice of commencement of the action or (iii) the
     indemnifying party has authorized the employment of counsel for the
     indemnified party at the expense of the indemnifying party; and except
     that, if clause (i) or (iii) is applicable, such liability shall be only in
     respect of the counsel referred to in such clause (i) or (iii).

          (d) In order to provide for just and equitable contribution in
     circumstances in which the indemnification provided for in paragraph (a) or
     (b) of this Section 8 is due in accordance with its terms but is for any
     reason unavailable on grounds of policy or otherwise, the Company and the
     Underwriters shall contribute to the aggregate losses, claims, damages and
     liabilities (including legal or other expenses reasonably incurred in
     connection with investigating or defending same) to which the Company and
     one or more of the Underwriters may be subject in such proportion as is
     appropriate to reflect the relative benefits received by the Company on the
     one hand and the Underwriters on the other from the offering of the
     Designated Certificates to which such loss, claim, damage, or liability (or
     action in respect thereof) relates. If the allocation

<PAGE>   24
                                      -24-


     provided by the immediately preceding sentence is not permitted by
     applicable law or if the indemnified party failed to give the notice
     required under subsection (c) above, then each indemnifying party shall
     contribute to such amount paid or payable to such indemnified party in such
     proportion as is appropriate to reflect not only such relative benefits but
     also the relative fault of the Company on the one hand and the Underwriters
     on the other in connection with the statements or omissions which resulted
     in such losses, claims, damages or liabilities (or actions in respect
     thereof), as well as any other relevant equitable considerations. The
     relative benefits received by the Company on the one hand and the
     Underwriters on the other shall be deemed to be in the same proportion as
     the total proceeds from such offering net of compensation paid to the
     Underwriters with respect thereto (but before deducting expenses) bear to
     the total underwriting discounts and commissions received by such
     Underwriters. The relative fault shall be determined by reference to, among
     other things, whether the untrue or alleged untrue statement of a material
     fact or the omission or alleged omission to state a material fact relates
     to information supplied by the Company or such Underwriters and the
     parties' relative intent, knowledge, access to information and opportunity
     to correct or prevent such statement or omission. The Company and the
     Underwriters agree that it would not be just and equitable if contribution
     pursuant to this subsection (d) were determined by pro rata allocation
     (even if the Underwriters were treated as one entity for such purpose) or
     by any other method of allocation which does not take account of the
     equitable considerations referred to above in this subsection (d). Any
     party entitled to contribution will, promptly after receipt of notice of
     commencement of any action, suit or proceeding (including any governmental
     investigation) against such party in respect of which a claim for
     contribution may be made against another party or parties under this
     paragraph (d), notify such party or parties from whom contribution may be
     sought, but the omission to so notify such party or parties shall not
     relieve the party or parties from whom contribution may be sought from any
     other obligation it or they may have here under or otherwise than under
     this paragraph (d), except to the extent that the party or parties is
     prejudiced thereby. The amount paid or payable by an indemnified party as a
     result of the losses, claims, damages or liabilities (or actions in respect

<PAGE>   25
                                      -25-


     thereof) referred to above in this subsection (d) shall be deemed to
     include any legal or other expenses reasonably incurred by such indemnified
     party in connection with investigating or defending any such action or
     claim. Notwithstanding the provisions of this subsection (d), no
     Underwriter shall be required to contribute any amount in excess of the
     amount by which (i) the total price at which the applicable Designated
     Certificates underwritten by it and distributed to the public were offered
     to the public exceeds (ii) the amount of any damages which such Underwriter
     has otherwise been required to pay by reason of such untrue or alleged
     untrue statement or omission or alleged omission. No person guilty of
     fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Act) shall be entitled to contribution from any person who was not guilty
     of such fraudulent misrepresentation. For purposes of this Section 8, each
     person who controls any Underwriter within the meaning of either the Act or
     the Exchange Act shall have the same rights to contribution as any
     Underwriter, and each person who controls the Company within the meaning of
     either the Act or the Exchange Act, each officer of the Company who shall
     have signed the Registration Statement and each director of the Company
     shall have the same rights to contribution as the Company, subject in each
     case to the provisions of this paragraph (d). The obligations of the
     Underwriters of Designated Certificates in this subsection (d) to
     contribute are several in proportion to their respective underwriting
     obligations with respect to such Designated Certificates and not joint.

     9. Default by an Underwriter. (a) If any Underwriter shall default in its
obligation to purchase the Designated Certificates which it has agreed to
purchase under the Underwriting Agreement relating to such Designated
Certificates, the Representatives with respect thereto may in their discretion
arrange for themselves or another party or other parties to purchase such
Designated Certificates on the terms contained herein. If within thirty-six
hours after such default by any Underwriter such Representatives do not arrange
for the purchase of such Designated Certificates, then the Company shall be
entitled to a further period of thirty-six hours within which to procure another
party or other parties reasonably satisfactory to the Representatives to
purchase such Designated Certificates on such terms. In the event that, within
the respective prescribed period, such Representatives notify the Company that
they have so arranged for the purchase of such

<PAGE>   26
                                      -26-


Designated Certificates, or the Company notifies such Representatives that it
has so arranged for the purchase of such Designated Certificates, such
Representatives or the Company shall have the right to postpone the Time of
Delivery for such Designated Certificates for a period of not more than seven
days, in order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus or in any other documents or
arrangements, and the Company agrees to file promptly any amendments or
supplements to the Registration Statement or the Prospectus which in the
reasonable opinion of such Representatives may thereby be made necessary. The
term "Underwriter" as used in this Agreement shall include any person
substituted under this Section with like effect as if such person had originally
been a party to the Underwriting Agreement with respect to such Designated
Certificates.

     (b) If, after giving effect to any arrangements for the purchase of the
Designated Certificates of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate face amount of any series of such Designated Certificates which
remains unpurchased does not exceed one-eleventh of the aggregate face amount of
the relevant series of such Designated Certificates, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the face amount
of Designated Certificates which such Underwriter agreed to purchase under the
Underwriting Agreement relating to such Designated Certificates and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the face amount of Designated Certificates which such
Underwriter agreed to purchase under such Underwriting Agreement) of the
Designated Certificates of such defaulting Underwriter or Underwriters for which
such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     (c) If, after giving effect to any arrangements for the purchase of the
Designated Certificates of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate face amount of any series of Designated Certificates which remains
unpurchased exceeds one-eleventh of the aggregate face amount of the relevant
series of such Designated Certificates, as referred to in subsection (b) above,
or if the Company shall not exercise the right described in subsection (b) above
to require non-defaulting Underwriters to purchase Designated Certificates of a
defaulting Underwriter or Underwriters, then the Underwriting Agreement relating
to such Designated Certificates shall there-

<PAGE>   27
                                      -27-


upon terminate, without liability on the part of any non-defaulting Underwriter
or the Company, except for the expenses to be borne by the Company and the
Underwriters as provided in Sections 7 and 12 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     10. Termination. Any Underwriting Agreement shall be subject to termination
in the discretion of the Representatives with respect thereto, by notice given
to the Company prior to Time of Delivery for the applicable Designated
Certificates, if prior to such time (i) trading in the Company's common stock
shall have been suspended by the Commission or the New York Stock Exchange or
trading in securities generally on the New York Stock Exchange shall have been
suspended or materially limited or minimum prices shall have been established on
such Exchange, (ii) a banking moratorium shall have been declared either by
Federal or New York State authorities or (iii) there shall have occurred any
material outbreak or material escalation of hostilities or other calamity or
crisis the effect of which on the financial markets of the United States is such
as to make it, in the reasonable judgment of such Representatives, impracticable
to market such Designated Certificates.

     11. Representations and Indemnities to Survive. The respective indemnities,
agreements, representations, warranties and other statements of the Company or
its officers and of the Underwriters as set forth in or made by or pursuant to
any Underwriting Agreement shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any such Underwriter or the Company or any of the officers, directors
or controlling persons of the Company or the Underwriters referred to in Section
8 hereof, and shall survive delivery of and payment for the Designated
Certificates relating to such Underwriting Agreement. The provisions of Sections
8, 11 and 12 of such Underwriting Agreement shall survive the termination or
cancellation of such Underwriting Agreement.

     12. Reimbursement of Underwriters' Expenses. If the Underwriting Agreement
relating to the sale of any Designated Certificates shall be terminated pursuant
to Section 9 or Section 10 hereof, then the Company shall not then be under any
liability to any Underwriter with respect to the Designated Certificates
relating to such Underwriting Agreement except as provided in Section 7 and
Section 8 hereof; but if the sale of any Designated Certificates is not
consummated because any condition set forth in Section 6 hereof is not
satisfied, because

<PAGE>   28
                                      -28-


of any termination pursuant to Section 10 hereof or because of any refusal,
inability or failure on the part of the Company to perform any agreement in the
Underwriting Agreement relating to such Designated Certificates or comply with
any provision thereof other than by reason of a default by any of the
Underwriters for such Designated Certificates, the Company will reimburse such
Underwriters severally through the Representatives upon demand for all
reasonable out-of-pocket expenses approved in writing by the Representatives
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Designated Certificates but the Company shall then be under no further liability
to any Underwriter with respect to such Designated Certificates except as
provided in Section 7 and Section 8 hereof.

     13. Notices. In all dealings hereunder, the Representatives of the
Underwriters of Designated Certificates shall act on behalf of each of such
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by such Representatives Jointly or by such of the Representatives, if any,
as may be designated for such purpose in the Pricing Agreement.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement: Attention: Treasurer (with a copy to the General
Counsel); provided, however, that any notice to an Underwriter pursuant to
Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire, or telex constituting such Questionnaire, which address will be
supplied to the Company by the Representatives upon request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

     14. Successors. Each Underwriting Agreement shall be binding upon, and
inure solely to the benefit of, the Underwriters thereunder, the Company and, to
the extent provided in Section 8 and Section 11 hereof, the officers and
directors of the Company and each person who controls the Company or any such
Underwriter, and their respective heirs, executors, admin-

<PAGE>   29
                                      -29-


istrators, successors and assigns, and no other person shall acquire or have any
right under or by virtue of such Underwriting Agreement. No purchaser of any of
the Pass Through Certificates from any Underwriter therefor shall be deemed a
successor or assign by reason merely of such purchase.

     15. Time is of Essence. Time shall be of the essence of each Underwriting
Agreement. As used herein, "business day" shall mean any day when the
Commission's office in Washington, D.C. is open for business and "New York
Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday
which is not a day on which banking institutions in New York are generally
authorized or obligated by law or executive order to close.

     16. APPLICABLE LAW. EACH UNDERWRITING AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     17. Counterparts. Each Underwriting Agreement may be executed by any one or
more of the parties thereto in any number of counterparts, each of which shall
be deemed to be an original, but all such respective counterparts shall together
constitute one and the same instrument.

                                                     Very truly yours,

                                                     ATLAS AIR, INC.

                  Section 1.03. Form of Documents Delivered to Trustee. In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such
Persons as to other matters and any such Person may certify or give an opinion
as to such matters in one or several documents.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Basic Agreement or this Agreement, they may, but
need not, be consolidated and form one instrument.

                  Section 1.04. Directions of Certificateholders. (a) Any
direction, consent, request, demand, authorization, notice, waiver or other
action provided by this Agreement in respect of the Certificates of any series
to be given or taken by Certificateholders (a "Direction") may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such Certificateholders in person or by an agent or proxy duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee and, when it is hereby expressly required pursuant to this Agreement, to
the Company or any Loan Trustee. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Certificateholders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such
<PAGE>   20
                                      -14-


agent or proxy shall be sufficient for any purpose of this Trust Agreement and
conclusive in favor of the Trustee, the Company and the related Loan Trustee, if
made in the manner provided in this Section 1.04.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the certificate of any notary public
or other officer of any jurisdiction authorized to take acknowledgments of deeds
or administer oaths that the Person executing such instrument acknowledged to
him the execution thereof, or by an affidavit of a witness to such execution
sworn to before any such notary or such other officer, and where such execution
is by an officer of a corporation or association or a member of a partnership,
on behalf of such corporation, association or partnership, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and
date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other reasonable manner
which the Trustee deems sufficient.

                  (c) In determining whether the Certificateholders of the
requisite Fractional Undivided Interests of Certificates of any series
Outstanding have given any Direction under this Agreement, Certificates owned by
the Company or any Affiliate thereof shall be disregarded and deemed not to be
Outstanding for purposes of any such determination. In determining whether the
Trustee shall be protected in relying upon any such Direction, only Certificates
which the Trustee knows to be so owned shall be so disregarded. Notwithstanding
the foregoing, (i) if any such Person owns 100% of the Certificates of any
series Outstanding, such Certificates shall not be so disregarded, and (ii) if
any amount of Certificates of any series so owned by any such Person have been
pledged in good faith, such Certificates shall not be disregarded if the pledgee
establishes to the satisfaction of the Trustee the pledgee's right so to act
with respect to such Certificates and that the pledgee is not the Company or any
Affiliate thereof.

                  (d) The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates of any series, entitled to
give any Direction. Notwithstanding Section 316(c) of the Trust Indenture Act,
such record date shall be the record date specified in such Officer's
Certificate, which shall be a date not more than 30 days prior to the first
solicitation of Certificateholders of the applicable series in connection
therewith. If such a record date is fixed, such Direction may be given before or
after such record date, but only the Certificateholders of record of the
applicable series at the close of business on such record date shall be deemed
to be Certificateholders for the purposes of determining whether
Certificateholders of the requisite proportion of Outstanding Certificates of
such series have authorized or agreed or consented to such Direction, and for
that purpose the Outstanding Certificates shall be computed as of such record
date; provided, however, that no such Direction by the Certificateholders on
such rec-
<PAGE>   21
                                      -15-


ord date shall be deemed effective unless it shall become effective pursuant to
the provisions of this Agreement not later than one year after such record date.

                  (e) Any Direction by the Holder of any Certificate shall bind
the Holder of every Certificate issued upon the transfer thereof or in exchange
therefor or in lieu thereof, whether or not notation of such Direction is made
upon such Certificate.

                  (f) Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates of such
series.

issued from time to time in one or more series and shall be designated generally
as the "Pass Through Certificates", with such further designations added or

designation so selected for the series to which it belongs. All Certificates of
the same series shall be substantially identical except that the Certificates of
a series may differ as to denomination and as may otherwise be provided in the
Trust Supplement establishing the Certificates of such series. Each series of
Certificates issued pursuant to this Agreement will evidence fractional
undivided interests in the related Trust and, except as may be contained in any
Intercreditor Agreement, will have no rights, benefits or interests in respect
of any other Trust or the Trust Property held therein. All Certificates of the
same series shall be in all respects equally and ratably entitled to the
benefits of this Agreement without preference, priority or distinction on
account of the actual time or times of authentication and delivery, all in
accordance with the terms and provisions of this Agreement.

         distinguish such Trust from each other Trust created under this Basic
         Agreement and a Trust Supplement);

                  (2)  the specific title of the Certificates of such series
         (which title shall distinguish the Certificates of such series from
         each other series of Certificates created under this Basic Agreement
         and a Trust Supplement);

                  (3)  any limit upon the aggregate principal amount of the
         Certificates of such series which may be authenticated and delivered
         (which limit shall not pertain to Certificates authenticated and
         delivered upon registration of transfer of, or in exchange for, or in
         lieu of, other Certificates of the series pursuant to Sections 3.03,
         3.04 and 3.06);

         denominations in which the Certificates of such series shall be
         issuable;

                  (9)  if other than United States dollars, the currency or
         currencies (including currency units) in which the Certificates of such
         series shall be denominated;

                  (10) the specific form of the Certificates of such series
         (including the interest rate applicable thereto) and whether or not
         Certificates of such series are to be issued as Book-Entry Certificates
         and, if such Certificates are to be Book-Entry Certificates, the form
         of Letter of Representations, if any (or, in the case of any
         Certificates denominated in a currency other than United States dollars

         hereof permit or require further specification in the related Trust
         Supplement;

                  (13) any restrictions (including legends) in respect of ERISA;

                  (14) whether such series will be subject to an Intercreditor
         Agreement and, if so, the specific designation of such Intercreditor
         Agreement;

                  (15) whether such series will have the benefit of a Liquidity
         Facility and, if so, any terms appropriate thereto;

                  (16) whether there will be a deposit agreement or other
         arrangement prior to the delivery of one or more Aircraft and, if so,
         any terms appropriate thereto; and

                  (17) any other terms of the Certificates of such series (which
         terms shall not be inconsistent with the provisions of the Trust
         Indenture Act), including any terms of the Certificates of such series
         which may be required or advisable under United States laws or
         regulations or advisable in connection with the marketing of
         Certificates of the series.

                  (c) At any time and from time to time after the execution and
delivery of this Basic Agreement and a Trust Supplement forming a Trust and
establishing the terms of Certificates of a series, Certificates of such series
shall be executed, authenticated and delivered by the Trustee to the Person or
Persons specified by the Company upon request of the Company and upon
satisfaction or waiver of any conditions precedent set forth in such Trust
Supplement or in any other document to which a Trustee is a party relating to
the issuance of the Certificates of such series.

                  Section 2.02. Acquisition of Equipment Notes. (a) Unless
otherwise specified in the related Trust Supplement, on or prior to the Issuance
Date of the Certificates of a series, the Trustee shall execute and deliver the
related Note Purchase Agreements in the form delivered to the Trustee by the
Company and shall, subject to the respective terms thereof, perform its
obligations under such Note Purchase Agreements. The Trustee shall issue and
sell such Certificates, in authorized denominations and in such Fractional
Undivided Interests, so as to result in the receipt of consideration in an
amount equal to the aggregate purchase price of the Equipment Notes contemplated
to be purchased by the Trustee under the related Note Purchase Agreements and,
concurrently therewith, the Trustee shall purchase, pursuant to the terms and
conditions of the Note Purchase Agreements, such Equipment Notes at a purchase
<PAGE>   24
                                      -18-


price equal to the amount of such consideration so received. Except as provided
in Sections 3.03, 3.04 and 3.06 hereof, the Trustee shall not execute,
authenticate or deliver Certificates of such series in excess of the aggregate
amount specified in this paragraph. The provisions of this Subsection (a) are
subject to the provisions of Subsection (b) below.

                  (b) If on or prior to the Issuance Date with respect to a
series of Certificates the Company shall deliver to the Trustee a Postponement
Notice relating to one or more Postponed Notes, the Trustee shall postpone the
purchase of such Postponed Notes and shall deposit into an escrow account (as to
such Trust, the "Escrow Account") to be maintained as part of the related Trust
an amount equal to the purchase price of such Postponed Notes (the "Escrowed
Funds"). The portion of the Escrowed Funds so deposited with respect to any
particular Postponed Notes shall be invested by the Trustee at the written
direction and risk of, and for the benefit of, the Responsible Party in
Specified Investments (i) maturing no later than any scheduled Transfer Date
relating to such Postponed Notes or (ii) if no such Transfer Date has been
scheduled, maturing on the next Business Day, or (iii) if the Company has given
notice to the Trustee that such Postponed Notes will not be issued, maturing on
the next applicable Special Distribution Date, if such investments are
reasonably available for purchase. The Trustee shall make withdrawals from the
Escrow Account only as provided in this Agreement. Upon request of the Company
on one or more occasions and the satisfaction or waiver of the closing
conditions specified in the applicable Note Purchase Agreements on or prior to
the related Cut-off Date, the Trustee shall purchase the applicable Postponed
Notes with the Escrowed Funds withdrawn from the Escrow Account. The purchase
price shall equal the principal amount of such Postponed Notes.

                  The Trustee shall hold all Specified Investments until the
maturity thereof and will not sell or otherwise transfer Specified Investments.
If Specified Investments held in an Escrow Account mature prior to any
applicable Transfer Date, any proceeds received on the maturity of such
Specified Investments (other than any earnings thereon) shall be reinvested by
the Trustee at the written direction and risk of, and for the benefit of, the
Responsible Party in Specified Investments maturing as provided in the preceding
paragraph.

                  Any earnings on Specified Investments received from time to
time by the Trustee shall be promptly distributed to the Responsible Party. The
Responsible Party shall pay to the Trustee for deposit to the relevant Escrow
Account an amount equal to any losses on such Specified Investments as incurred.
On the Initial Regular Distribution Date in respect of the Certificates of any
series, the Responsible Party will pay (in immediately available funds) to the
Trustee an amount equal to the interest that would have accrued on any Postponed
Notes with respect to such Certificates, if any, purchased after the Issuance
Date if such Postponed Notes had been purchased on the Issuance Date, from the
Issuance Date to, but not including, the date of the purchase of such Postponed
Notes by the Trustee.
<PAGE>   25
                                      -19-


                  If, in respect of the Certificates of any series, the Company
notifies the Trustee prior to the Cut-off Date that any Postponed Notes will not
be issued on or prior to the Cut-off Date for any reason, on the next Special
Distribution Date for such Certificates occurring not less than 15 days
following the date of such notice, (i) the Responsible Party shall pay to the
Trustee for deposit in the related Special Payments Account, in immediately
available funds, an amount equal to the interest that would have accrued on the
Postponed Notes designated in such notice at a rate equal to the interest rate
applicable to such Certificates from the Issuance Date to, but not including,
such Special Distribution Date and (ii) the Trustee shall transfer an amount
equal to that amount of Escrowed Funds that would have been used to purchase the
Postponed Notes designated in such notice and the amount paid by the Responsible
Party pursuant to the immediately preceding clause (i) to the related Special
Payments Account for distribution as a Special Payment in accordance with the
provisions hereof.

                  If, on such Cut-off Date, an amount equal to less than all of
the Escrowed Funds (other than Escrowed Funds referred to in the immediately
preceding paragraph) has been used to purchase Postponed Notes, on the next such
Special Distribution Date occurring not less than 15 days following such Cut-off
Date (i) the Responsible Party shall pay to the Trustee for deposit in such
Special Payments Account, in immediately available funds, an amount equal to the
interest that would have accrued on such Postponed Notes contemplated to be
purchased with such unused Escrowed Funds (other than Escrowed Funds referred to
in the immediately preceding paragraph) but not so purchased at a rate equal to
the interest rate applicable to such Certificates from the Issuance Date to, but
not including, such Special Distribution Date and (ii) the Trustee shall
transfer such unused Escrowed Funds and the amount paid by the Responsible Party
pursuant to the immediately preceding clause (i) to such Special Payments
Account for distribution as a Special Payment in accordance with the provisions
hereof.

                  Section 2.03. Acceptance by Trustee. The Trustee, upon the
execution and delivery of a Trust Supplement creating a Trust and establishing a
series of Certificates, shall acknowledge its acceptance of all right, title and
interest in and to the Trust Property to be acquired pursuant to Section 2.02
hereof and the related Note Purchase Agreements and shall declare that the
Trustee holds and will hold all such right, title and interest for the benefit
of all then present and future Certificateholders of such series, upon the
trusts herein and in such Trust Supplement set forth. By the acceptance of each
Certificate of such series issued to it under this Agreement, each initial
Holder of such series as grantor of such Trust shall thereby join in the
creation and declaration of such Trust.

                  Section 2.04. Limitation of Powers. The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes provided
for in the related Trust Supplement, and, except as set forth herein, the
Trustee shall not be authorized or empowered to acquire any other investments or
engage in any other activities and, in particular, the Trustee shall not be
authorized or empowered to do anything that would cause such Trust to fail to
qualify as a "grantor trust" for federal income tax purposes (including, as
subject to this restriction, acquiring any Aircraft (as defined in the
respective Indentures) by bidding such Equipment Notes or otherwise, or taking
any action with respect to any such Aircraft once acquired).

Certificates of such series shall be typed, printed, lithographed or engraved or
produced by any combination of these methods or may be produced in any other
manner permitted by the rules of any securities exchange on which the
Certificates may be listed, all as determined by the officers executing such
Certificates, as evidenced by their execution of such Certificates.

                  Except as otherwise provided in the related Trust Supplement,
the Certificates of each series shall be issued in minimum denominations of
$1,000 or integral multiples thereof except that one Certificate of such series
may be issued in a different denomination.

                  The Certificates of such series shall be executed on behalf of
the Trustee by manual or facsimile signature of a Responsible Officer of the
Trustee. Certificates of any series bearing the manual or facsimile signature of
an individual who was, at the time when such signature was affixed, authorized
to sign on behalf of the Trustee shall be valid and binding obligations of the
Trustee, notwithstanding that such individual has ceased to be so authorized
prior to the authentication and delivery of such Certificates or did not hold
such office at the date of such Certificates.

                  Section 3.02. Authentication of Certificates. (a) On the
Issuance Date, the Trustee shall duly execute, authenticate and deliver
Certificates of each series in authorized denominations equalling in the
aggregate the aggregate principal amount of the Equipment Notes that may be
purchased by the Trustee pursuant to the related Note Purchase Agreements, and
evidencing the entire ownership of the related Trust. Thereafter, the Trustee
shall duly execute, authenticate and deliver the Certificates of such series as
herein provided.

                  (b) No Certificate of any series shall be entitled to any
benefit under this Agreement or be valid for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
set forth in Exhibit A hereto executed by the Trustee by the manual signature of
one of its authorized signatories, and such certificate of authentication upon
any Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates of any series shall be dated the date of their authentication.

                  Section 3.03. Temporary Certificates. Until definitive
Certificates are ready for delivery, the Trustee shall execute, authenticate and
deliver temporary Certificates of each series. Temporary Certificates of each
series shall be substantially in the form of definitive Certificates of each
series but may have insertions, substitutions, omissions and other variations
determined to be appropriate by the officers executing the temporary
Certificates of each series, as evidenced by their execution of such temporary
Certificates. If temporary Certificates of any series are issued, the Trustee
will cause definitive Certificates of each series to be prepared without
unreasonable delay. After the preparation of definitive Certificates of each
series, the temporary Certificates shall be exchangeable for definitive
Certificates upon surrender of the temporary Certificates at the office or
agency of the Trustee designated for such purpose pursuant to Section 7.12,
without charge to the Certificateholder. Upon surrender for cancellation of any
one or more temporary Certificates, the Trustee shall execute, authenticate and
deliver in exchange therefor a like face amount of definitive Certificates of
like series, in authorized denominations and of a like Fractional Undivided
Interest. Until so exchanged, the temporary Certificates shall be entitled to
the same benefits under this Agreement as definitive Certificates.

                  Section 3.04. Transfer and Exchange. The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with the
provisions of Section 7.12 of this Agreement a register (the "Register") for
each series of Certificates in which, subject to such reasonable regulations as
it may prescribe, the Trustee shall provide for the registration of the
Certificates of such series and of transfers and exchanges of such Certificates
as herein provided. The Trustee shall initially be the registrar (the
"Registrar") for the purpose of registering such Certificates of each series and
transfers and exchanges of such Certificates as herein provided.

                  All Certificates issued upon any registration of transfer or
exchange of Certificate of any series shall be valid obligations of the
applicable Trust, evidencing the same interest therein, and entitled to the same
benefits under this Agreement, as the Certificates of such series surrendered
upon such registration of transfer or exchange.

                  Upon surrender for registration of transfer of any Certificate
at the Corporate Trust Office or such other office or agency, the Trustee shall
execute, authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of like series, in authorized
denominations of a like aggregate Fractional Undivided Interest.

                  At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of like series, in authorized denominations and
of a like aggregate Fractional Undivided Interest, upon surrender of the
Certificates to be exchanged at any such office or agency. Whenever any
Certificates are so surrendered for exchange, the Trustee shall execute,
authenticate and deliver the Certificates that the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
registration of transfer or exchange shall be duly endorsed or accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Registrar duly executed by the Certificateholder thereof or its attorney duly
authorized in writing.

                  No service charge shall be made to a Certificateholder for any
registration of transfer or exchange of Certificates, but the Trustee shall
require payment of a sum sufficient to cover any tax or similar governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates. Certificates surrendered for registration of transfer or exchange
shall be canceled and subsequently destroyed by the Trustee.

                  Section 3.05. Book-Entry and Definitive Certificates.

                  (a) The Certificates of any series may be issued in the form
of one or more typewritten Certificates representing the Book-Entry Certificates
of such series, to be delivered to The Depository Trust Company, the initial
Clearing Agency, by, or on behalf of, the Company. In such case, the
Certificates of such series delivered to The Depository Trust Company shall
initially be registered on the Register in the name of CEDE & Co., the nomi-

                                      -23-


nee of the initial Clearing Agency, and no Certificate Owner will receive a
definitive certificate representing such Certificate Owner's interest in the
Certificates of such series, except as provided above and in Subsection (d)
below. As to the Certificates of any series, unless and until definitive, fully
registered Certificates (the "Definitive Certificates") have been issued
pursuant to Subsection (d) below:

                  (i)   the provisions of this Section 3.05 shall be in full
         force and effect;

                  (ii)  the Company, the Paying Agent, the Registrar and the
         Trustee may deal with the Clearing Agency Participants for all purposes
         (including the making of distributions on the Certificates) as the
         authorized representatives of the Certificate Owners;

                  (iii) to the extent that the provisions of this Section 3.05
         conflict with any other provisions of this Agreement (other than the
         provisions of any Trust Supplement expressly amending this Section 3.05
         as permitted by this Basic Agreement), the provisions of this Section
         3.05 shall control;

                  (iv)  the rights of Certificate Owners shall be exercised only
         through the Clearing Agency and shall be limited to those established
         by law and agreements between such Certificate Owners and the Clearing
         Agency Participants; and until Definitive Certificates are issued
         pursuant to Subsection (d) below, the Clearing Agency will make
         book-entry transfers among the Clearing Agency Participants and receive
         and transmit distributions of principal, interest and premium, if any,
         on the Certificates to such Clearing Agency Participants; and

                   (v)  whenever this Agreement requires or permits actions to
         be taken based upon instructions or directions of Certificateholders of
         such series holding Certificates of such series evidencing a specified
         percentage of the Fractional Undivided Interests in the related Trust,
         the Clearing Agency shall be deemed to represent such percentage only
         to the extent that it has received instructions to such effect from
         Clearing Agency Participants owning or representing, respectively, such
         required percentage of the beneficial interest in Certificates of such
         series and has delivered such instructions to the Trustee. The Trustee
         shall have no obligation to determine whether the Clearing Agency has
         in fact received any such instructions.

                  (b) Whenever notice or other communication to the
Certificateholders of such series is required under this Agreement, unless and
until Definitive Certificates shall have been issued pursuant to Subsection (e)
below, the Trustee shall give all such notices and communications specified
herein to be given to Certificateholders of such series to the Clearing Agency.
<PAGE>   30
                                      -24-


                  (c) Unless and until Definitive Certificates of a series are
issued pursuant to Subsection (d) below, on the Record Date prior to each
applicable Regular Distribution Date and Special Distribution Date, the Trustee
will request from the Clearing Agency a securities position listing setting
forth the names of all Clearing Agency Participants reflected on the Clearing
Agency's books as holding interests in the Certificates on such Record Date.

                  (d) If with respect to the Certificates of any series (i) the
Company advises the Trustee in writing that the Clearing Agency is no longer
willing or able to discharge properly its responsibilities and the Trustee or
the Company is unable to locate a qualified successor, (ii) the Company, at its
option, advises the Trustee in writing that it elects to terminate the
book-entry system through the Clearing Agency or (iii) after the occurrence of
an Event of Default, Certificate Owners of Book-Entry Certificates of such
series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the related Trust, by Act of such Certificate Owners
delivered to the Company and the Trustee, advise the Company, the Trustee and
the Clearing Agency through the Clearing Agency Participants in writing that the
continuation of a book-entry system through the Clearing Agency Participants is
no longer in the best interests of the Certificate Owners of such series, then
the Trustee shall notify all Certificate Owners of such series, through the
Clearing Agency, of the occurrence of any such event and of the availability of
Definitive Certificates. Upon surrender to the Trustee of all the Certificates
of such series held by the Clearing Agency, accompanied by registration
instructions from the Clearing Agency Participants for registration of
Definitive Certificates in the names of Certificate Owners of such series, the
Trustee shall issue and deliver the Definitive Certificates of such series in
accordance with the instructions of the Clearing Agency. Neither the Company,
the Registrar, the Paying Agent nor the Trustee shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such registration instructions. Upon the issuance of
Definitive Certificates of such series, the Trustee shall recognize the Person
in whose name the Definitive Certificates are registered in the Register as
Certificateholders hereunder. Neither the Company nor the Trustee shall be
liable if the Trustee or the Company is unable to Locate a qualified successor
Clearing Agency.

                  (e) Except as otherwise provided in the related Trust
Supplement, the Trustee shall enter into the applicable Letter of
Representations with respect to such series of Certificates and fulfill its
responsibilities thereunder.

                  (f) The provisions of this Section 3.05 may be made
inapplicable to any series or may be amended with respect to any series in the
related Trust Supplement.

                  Section 3.06. Mutilated, Destroyed, Lost or Stolen
Certificates. If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the
<PAGE>   31
                                      -25-


Registrar and the Trustee such security, indemnity or bond, as may be required
by them to save each of them harmless, then, in the absence of notice to the
Registrar or the Trustee that such destroyed, lost or stolen Certificate has
been acquired by a bona fide purchaser, and provided that the requirements of
Section 8-405 of the Uniform Commercial Code in effect in any applicable
jurisdiction are met, the Trustee shall execute, authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate or Certificates of like series, in authorized
denominations and of like Fractional Undivided Interest and bearing a number not
contemporaneously outstanding.

                  In connection with the issuance of any new Certificate under
this Section 3.06, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.

                  Any duplicate Certificate issued pursuant to this Section 3.06
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the related Trust, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

                  The provisions of this Section 3.06 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Certificates.

                  Section 3.07. Persons Deemed Owners. Prior to due presentment
of a Certificate for registration of transfer, the Trustee, the Registrar and
any Paying Agent may treat the Person in whose name any Certificate is
registered (as of the day of determination) as the owner of such Certificate for
the purpose of receiving distributions pursuant to Article IV and for all other
purposes whatsoever, and none of the Trustee, the Registrar or any Paying Agent
shall be affected by any notice to the contrary.

                  Section 3.08. Cancellation. All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar for
cancellation and shall promptly be canceled by it. No Certificates shall be
authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section 3.08, except as expressly permitted by this Agreement.
All cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                  Section 3.09. Limitation of Liability for Payments. All
payments and distributions made to Certificateholders of any series in respect
of the Certificates of such series shall be made only from the Trust Property of
the related Trust and only to the extent that the Trustee shall have sufficient
income or proceeds from the Trust Property to make such pay-
<PAGE>   32
                                      -26-


ments in accordance with the terms of Article IV of this Agreement. Each
Certificateholder, by its acceptance of a Certificate, agrees that it will look
solely to the income and proceeds from the Trust Property of the related Trust
for any payment or distribution due to such Certificateholder pursuant to the
terms of this Agreement and that it will not have any recourse to the Company,
the Trustee, the Loan Trustees, the Liquidity Providers, the Owner Trustees or
the Owner Participants, except as otherwise expressly provided herein or in the
Intercreditor Agreement.

                  The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise expressly
provided herein).

                          DISTRIBUTIONS; STATEMENTS TO
                               CERTIFICATEHOLDERS

                  Section 4.01. Certificate Account and Special Payments
Account. (a) The Trustee shall establish and maintain on behalf of the
Certificateholders of each series a Certificate Account as one or more
non-interest-bearing accounts. The Trustee shall hold such Certificate Account
in trust for the benefit of the Certificateholders of such series, and shall
make or permit withdrawals therefrom only as provided in this Agreement. On each
day when a Scheduled Payment is made to the Trustee (under the Intercreditor
Agreement, if applicable) with respect to the Certificates of such series, the
Trustee, upon receipt thereof, shall immediately deposit the aggregate amount of
such Scheduled Payment in such Certificate Account.

                  (b) The Trustee shall establish and maintain on behalf of the
Certificateholders of each series a Special Payments Account as one or more
accounts, which shall be non-interest bearing except as provided in Section
4.04. The Trustee shall hold the Special Payments Account in trust for the
benefit of the Certificateholders of such series and shall make or permit
withdrawals therefrom only as provided in this Agreement. On each day when one
or more Special Payments are made to the Trustee (under the Intercreditor
Agreement, if applicable) with respect to the Certificates of such series, the
Trustee, upon receipt thereof, shall immediately deposit the aggregate amount of
such Special Payments in such Special Payments Account.

                  (c) The Trustee shall present (or, if applicable, cause the
Subordination Agent to present) to the related Loan Trustee of each Equipment
Note such Equipment Note on the date of its stated final maturity or, in the
case of any Equipment Note which is to be redeemed
<PAGE>   33
                                      -27-


in whole pursuant to the related Indenture, on the applicable redemption date
under such Indenture.

                  Section 4.02. Distributions from Certificate Account and
Special Payments Account. (a) On each Regular Distribution Date with respect to
a series of Certificates or as soon thereafter as the Trustee has confined
receipt of the payment of all or any part of the Scheduled Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a). There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder) of the total
amount in the applicable Certificate Account, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                  (b) On each Special Distribution Date with respect to any
Special Payment with respect to a series of Certificates or as soon thereafter
as the Trustee has confirmed receipt of any Special Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust or realized upon the sale of such Equipment Notes, the Trustee shall
distribute out of the applicable Special Payments Account the entire amount of
such applicable Special Payment deposited therein pursuant to Section 4.01(b).
There shall be so distributed to each Certificateholder of record of such series
on the Record Date with respect to such Special Distribution Date (other than as
provided in Section 11.01 concerning the final distribution) by check mailed to
such Certificateholder, at the address appearing in the Register, such
Certificateholder's pro rata share (based on the Fractional Undivided Interest
in the related Trust held by such Certificateholder) of the total amount in the
applicable Special Payments Account on account of such Special Payment, except
that, with respect to Certificates registered on the Record Date in the name of
a Clearing Agency (or its nominee), such distribution shall be made by wire
transfer in immediately available funds to the account designated by such
Clearing Agency (or such nominee).

                  (c) The Trustee shall, at the expense of the Company, cause
notice of each Special Payment with respect to a series of Certificates to be
mailed to each Certificateholder at his address as it appears in the Register.
In the event of redemption or purchase of Equipment Notes held in the related
Trust, such notice shall be mailed not less than 15 days prior to the Special
Distribution Date for the Special Payment resulting from such redemption or
purchase, which Special Distribution Date shall be the date of such redemption
or purchase. In the event that the Trustee receives a notice from the Company
that Postponed Notes will not be purchased by the Trustee pursuant to Section
2.02, such notice of Special Payment shall be mailed as soon as practicable
after receipt of such notice from the Company and shall state the Special
Distribution Date for such Special Payment, which shall occur 15 days after the
date of such notice of Special Payment or (if such 15th day is not practicable)
as soon as practicable thereafter. In the event that any Special Payment is to
be made pursuant to the last paragraph of Section 2.02(b) hereof, there shall be
mailed on the Cut-off Date (or, if such mailing on the Cut-off Date is not
practicable, as soon as practicable after the Cut-off Date), notice of such
Special Payment stating the Special Distribution Date for such Special Payment,
which shall occur 15 days after the date of such notice of such Special Payment
(or, if such 15th day is not practicable, as soon as practicable thereafter). In
the case of any other Special Payments, such notice shall be mailed as soon as
practicable after the Trustee has confirmed that it has received funds for such
Special Payment, stating the Special Distribution Date for such Special Payment
which shall occur not less than 15 days after the date of such notice and as
soon as practicable thereafter. Notices mailed by the Trustee shall set forth:

                  (i)   the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);

                  (ii)  the amount of the Special Payment (taking into account
         any payment to be made by the Company pursuant to Section 2.02(b)) for
         each $1,000 face amount Certificate and the amount thereof constituting
         principal, premium, if any, and interest;

                  (iii) the reason for the Special Payment; and

                  (iv)  if the Special Distribution Date is the same date as a
         Regular Distribution Date for the Certificates, the total amount to be
         received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase of
an Equipment Note has not been calculated at the time that the Trustee mails
notice of a Special Payment, it shall be sufficient if the notice sets forth the
other amounts to be distributed and states that any premium received will also
be distributed.
<PAGE>   35
                                      -29-


                  If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

                  Section 4.03. Statements to Certificateholders. (a) On each
Regular Distribution Date and Special Distribution Date, the Trustee will
include with each distribution of a Scheduled Payment or Special Payment, as the
case may be, to Certificateholders of the related series a statement setting
forth the information provided below. Such statement shall set forth (per $1,000
aggregate principal amount of Certificate as to (i) and (ii) below) the
following information:

                  (i)   the amount of such distribution hereunder allocable to
         principal and the amount allocable to premium, if any;

                  (ii)  the amount of such distribution under this Agreement
         allocable to interest;

                  (iii) the Pool Balance and the Pool Factor of the related
         Trust.

                  With respect to the Certificates registered in the name of a
Clearing Agency or its nominee, on the Record Date prior to each Distribution
Date, the Trustee will request from the Clearing Agency a securities position
listing setting forth the names of all Clearing Agency Participants reflected on
the Clearing Agency's books as holding interests in the Certificates on such
Record Date. On each Distribution Date, the Trustee will mail to each such
Clearing Agency Participant the statement described above and will make
available additional copies as requested by such Clearing Agency Participant for
forwarding to holders of interests in the Certificates.

                  (b) Within a reasonable period of time after the end of each
calendar year but not later than the latest date permitted by law, the Trustee
shall furnish to each Person who at any time during such calendar year was a
Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i) and (a)(ii) above with respect to the
related Trust for such calendar year or, in the event such Person was a
Certificateholder of record during a portion of such calendar year, for the
applicable portion of such year, and such other items as are readily available
to the Trustee and which a Certificateholder shall reasonably request as
necessary for the purpose of such Certificateholder's preparation of its federal
income tax returns. With respect to Certificates registered in the name of a
Clearing Agency or its nominee, such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner
described in Section 4.03(a).

                  Section 4.04. Investment of Special Payment Moneys. Any money
received by the Trustee pursuant to Section 4.01(b) representing a Special
Payment which is not distributed on the date received shall, to the extent
practicable, be invested in Permitted Investments by the Trustee pending
distribution of such Special Payment pursuant to Section 4.02. Any investment
made pursuant to this Section 4.04 shall be in such Permitted Investments having
maturities not later than the date that such moneys are required to be used to
make the payment required under Section 4.02 on the applicable Special
Distribution Date and the Trustee shall hold any such Permitted Investments
until maturity. The Trustee shall have no liability with respect to any
investment made pursuant to this Section 4.04, other than by reason of the
willful misconduct or negligence of the Trustee. All income and earnings from
such investments shall be distributed on such Special Distribution Date as part
of such Special Payment.

at its own cost and expense, will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence, rights and

         all of the assets of the Company as an entirety shall execute and
         deliver to the Trustee applicable to the Certificates of each series a
         duly authorized, valid, binding and enforceable agreement in form and
         substance reasonably satisfactory to the Trustee containing an
         assumption by such successor corporation or Person of the due and
         punctual performance and observance of each covenant and condition of
         the Note Documents and of this Agreement applicable to the Certificates
         of each series to be performed or observed by the Company; and

conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Agreement
applicable to the Certificates of each series with the same effect as if such

as an entirety shall have the effect of releasing any successor corporation or
Person which shall have become such in the manner prescribed in this Section
5.02 from its liability in respect of this Agreement and any Note Document
applicable to the Certificates of such series to which it is a party.

Upon the occurrence and during the continuation of any Indenture Default under
any Indenture, the Trustee may (i) to the extent it is the Controlling Party at

                  (b) Purchase Rights of Certificateholders: At any time after
the occurrence and during the continuation of a Triggering Event, each
Certificateholder of Certificates of certain series (each, a "Potential
Purchaser" and, collectively, the "Potential Purchasers") will have certain
rights to purchase the Certificates of one or more other series, all as set
forth in the Trust Supplement applicable to the Certificates held by such
Potential Purchaser. The purchase price with respect to the Certificates of any
series shall be equal to the Pool Balance of the Certificates of such series,
together with accrued and unpaid interest thereon to the date of such purchase,
without premium, but including any other amounts then due and payable to the
Certificateholders of such series under this Agreement, any related
Intercreditor Agreement or any other Note Document or on or in respect of the
Certificates of such series; provided, however, that if such purchase occurs
after a Record Date, such purchase price shall be reduced by the amount to be
distributed hereunder on the related Distribution Date (which deducted amounts
shall remain distributable to, and may be retained by, the Certificateholder as
of such Record Date); provided, further, that no such purchase of Certificates
of such series shall be effective unless the purchasing Certificateholder (each,
a "Purchasing Certificateholder" and, collectively, the "Purchasing
Certificateholders") shall certify to the Trustee that contemporaneously with
such purchase, one or more Purchasing Certificateholders are purchasing,
pursuant to the terms of this Agreement and the other Agreements, if any,
relating to the Certificates of a series that are subject to the same
Intercreditor Agreement (such other Agreements, the "Other Agreements"), the
Certificates of each such series that the Trust Supplement applicable to the
Certificates held by the Purchasing Certificateholder specifies may be purchased
by such Purchasing Certificateholder. Each payment of the purchase price of the
Certificates of any series shall be made to an account or accounts designated by
the Trustee and each such purchase shall be subject to the terms of this Section
6.01. By acceptance of its Certificate, each Certificateholder (each, a "Selling
Certificateholder" and, collectively, the "Selling Certificateholders") of a
series that is subject to purchase by Potential Purchasers, all as set forth in
the Trust Supplement applicable to the Certificates held by the Selling
Certificateholders, agrees that, at any time after the occurrence and during the
continuance of a Triggering Event, it will, upon payment of the purchase price
specified herein by one or more Purchasing Certificateholders, forthwith sell,
assign, transfer and convey to such Purchasing Certificateholder (without
recourse, representation or warranty of any kind except for its own acts), all
of the right, title, interest and obligation of such Selling Certificateholder
in this Agreement, any related Intercreditor Agreement, the related Liquidity
Facility, the related Note Documents and all Certificates of such series held by
such Selling Certificateholder (excluding all right, title and interest under
any of the foregoing to the extent such right, title or interest is with respect
to an obligation not then due and payable as respects any action or inaction or
state of affairs occurring prior to such sale) and the Purchasing
Certificateholder shall assume all of such Selling Certificateholder's
obligations under this Agreement, any related Intercreditor Agreement, the
related Liquidity Facility and the related Note Documents. The Certificates of
such series will be deemed to be purchased on the date payment of the purchase
price is made notwithstanding the failure of any Selling Certificateholder to
deliver any
<PAGE>   39
                                      -33-


Certificates of such series and, upon such a purchase, (i) the only rights of
the Selling Certificateholders will be to deliver the Certificates to the
Purchasing Certificateholder and receive the purchase price for such
Certificates of such series and (ii) if the Purchasing Certificateholder shall
so request, such Selling Certificateholder will comply with all of the
provisions of Section 3.04 hereof to enable new Certificates of such series to
be issued to the Purchasing Certificateholder in such denominations as it shall
request. All charges and expenses in connection with the issuance of any such
new Certificates shall be borne by the Purchasing Certificateholder.

                  Section 6.02. Incidents of Sale of Equipment Notes. Upon any
sale of all or any part of the Equipment Notes held in the Trust made either
under the power of sale given under this Agreement or otherwise for the
enforcement of this Agreement, the following shall be applicable:

                  (a) Certificateholders and Trustee May Purchase Equipment
         Notes. Any Certificateholder, the Trustee in its individual or any
         other capacity or any other Person may bid for and purchase any of the
         Equipment Notes held in the Trust, and upon compliance with the terms
         of sale, may hold, retain, possess and dispose of such Equipment Notes
         in their own absolute right without further accountability.

                  (b) Receipt of Trustee Shall Discharge Purchaser. The receipt
         of the Trustee making such sale shall be a sufficient discharge to any
         purchaser for his purchase money, and, after paying such purchase money
         and receiving such receipt, such purchaser or its personal
         representative or assigns shall not be obliged to see to the
         application of such purchase money, or be in any way answerable for any
         loss, misapplication or nonapplication thereof.

                  (c) Application of Moneys Received upon Sale. Any moneys
         collected by the Trustee upon any sale made either under the power of
         sale given by this Agreement or otherwise for the enforcement of this
         Agreement shall be applied as provided in Section 4.02.

                  Section 6.03. Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit. If there shall be a failure to make payment of the
principal of, premium, if any, or interest on any Equipment Note held in the
related Trust, or if there shall be any failure to pay Rent (as defined in the
relevant Lease) under any Lease when due and payable, then the Trustee, in, its
own name and as trustee of an express trust, as holder of such Equipment Notes,
to the extent permitted by and in accordance with the terms of any related
Intercreditor Agreement and any related Note Documents (subject to rights of the
applicable Owner Trustee or Owner Participant to cure any such failure to pay
principal of, premium, if any, or interest on any Equipment Note or to pay Rent
under any Lease in accordance with the applicable Indenture), shall be entitled
and empowered to institute any suits, actions or proceedings at law, in equity
<PAGE>   40
                                      -34-


or otherwise, for the collection of the sums so due and unpaid on such Equipment
Notes or under such Lease and may prosecute any such claim or proceeding to
judgment or final decree with respect to the whole amount of any such sums so
due and unpaid.

                  Section 6.04. Control by Certificateholders. Subject to
Section 6.03 and the related Intercreditor Agreement, the Certificateholders
holding Certificates of a series evidencing Fractional Undivided Interests
aggregating not less than a majority in interest in the related Trust shall have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee with respect to the Trust or pursuant to the
terms of the Intercreditor Agreement, or exercising any trust or power conferred
on the Trustee under this Agreement or the Intercreditor Agreement, including
any right of the Trustee as Controlling Party under such Intercreditor Agreement
or as holder of the Equipment Notes held in the related Trust; provided,
however, that

                  (a) such Direction shall not in the opinion of the Trustee be
         in conflict with any rule of law or with this Agreement and would not
         involve the Trustee in personal liability or expense,

                  (b) the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders of
         such series not taking part in such Direction, and

                  (c) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such Direction.

                  Section 6.05. Waiver of Past Defaults. Subject to any related
Intercreditor Agreement, the Certificateholders holding Certificates of a series
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in the Trust (i) may on behalf of all of the Certificateholders
waive any past Event of Default hereunder and its consequences or (ii) if the
Trustee is the Controlling Party, may direct the Trustee to instruct the
applicable Loan Trustee to waive any past Indenture Event of Default under any
related Indenture and its consequences, and thereby annul any Direction given by
such Certificateholders or the Trustee to such Loan Trustee with respect
thereto, except a default:

                  (a) in the deposit of any Scheduled Payment or Special Payment
         under Section 4.01 or in the distribution of any payment under Section
         4.02 on the Certificates of a series, or

                  (b) in the payment of the principal of (premium, if any) or
         interest on the Equipment Notes held in the related Trust, or
<PAGE>   41
                                      -35-


                  (c) in respect of a covenant or provision hereof which under
         Article IX hereof cannot be modified or amended without the consent of
         each Certificateholder holding an Outstanding Certificate of a series
         affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates of such series and any Event of Default arising therefrom shall be
deemed to have been cured for every purpose and any direction given by the
Trustee on behalf of the Certificateholders of such series to the relevant Loan
Trustee shall be annulled with respect thereto; but no such waiver shall extend
to any subsequent or other default or Event of Default or impair any right
consequent thereon. Upon any such waiver, the Trustee shall vote the Equipment
Notes issued under the relevant Indenture to waive the corresponding Indenture
Event of Default.

                  Section 6.06. Right of Certificateholders to Receive Payments
Not To Be Impaired. Anything in this Agreement to the contrary notwithstanding,
including, without limitation, Section 6.07 hereof, but subject to any related
Intercreditor Agreement, the right of any Certificateholder to receive
distributions of payments required pursuant to Section 4.02 hereof on the
applicable Certificates when due, or to institute suit for the enforcement of
any such payment on or after the applicable Regular Distribution Date or Special
Distribution Date, shall not be impaired or affected without the consent of such
Certificateholder.

                  Section 6.07. Certificateholders May Not Bring Suit Except
Under Certain Conditions. A Certificateholder shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise with
respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

                  (a) such Certificateholder previously shall have given written
         notice to the Trustee of a continuing Event of Default;

                  (b) Certificateholders holding Certificates of such series
         evidencing Fractional Undivided Interests aggregating not less than 25%
         of the related Trust shall have requested the Trustee in writing to
         institute such action, suit or proceeding and shall have offered to the
         Trustee indemnity as provided in Section 7.03(e);

                  (c) the Trustee shall have refused or neglected to institute
         any such action, suit or proceeding for 60 days after receipt of such
         notice, request and offer of indemnity; and

                  (d) no direction inconsistent with such written request shall
         have been given to the Trustee during such 60-day period by
         Certificateholders holding Certificates of such series evidencing
         Fractional Undivided Interests aggregating not less than a majority in
         interest in the Trust.

                  It is understood and intended that no one or more of the
Certificateholders of any series shall have any right in any manner whatsoever
hereunder or under the related Trust Supplement or under the Certificates of
such series to (i) surrender, impair, waive, affect, disturb or prejudice any
property in the Trust Property of the Trust, or the lien of any related
Indenture on any property subject thereto, or the rights of the
Certificateholders of such series or the holders of the Equipment Notes, (ii)
obtain or seek to obtain priority over or preference with respect to any other
such Certificateholder of such series or (iii) enforce any right under this
Agreement, except in the manner herein provided and for the equal, ratable and
common benefit of all the Certificateholders of such series subject to the
provisions of this Agreement.

                  Section 6.08. Remedies Cumulative. Every remedy given
hereunder to the Trustee or to any of the Certificateholders of any series shall
not be exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                  Section 6.09. Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in the
manner and to the extent provided in the Trust Indenture Act; provided, however,
that neither this Section 6.09 nor the Trust Indenture Act shall be deemed to
authorize any court to require such an undertaking or to make such an assessment
in any suit instituted by the Company.

                                   THE TRUSTEE

                  Section 7.01. Certain Duties and Responsibilities. (a) Except
during the continuance of an Event of Default in respect of a Trust, the Trustee
undertakes to perform such duties in respect of the Trust as are specifically
set forth in this Agreement, and no implied covenants or obligations shall be
read into this Agreement against the Trustee.

                  (b) In case an Event of Default in respect of a Trust has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                  (c) No provision of this Agreement shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that

                  (i) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section 7.01; and

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer of the Trustee, unless it
         shall be proved that the Trustee was negligent in ascertaining the
         pertinent facts.

                  (d) Whether or not herein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 7.01.

transmit by mail to the Company, any related Owner Trustees, any related Owner
Participants, the related Loan Trustees and the Certificateholders holding
Certificates of the related series in accordance with Section 313(c) of the
Trust Indenture Act, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal, premium, if
any, or interest on any Equipment Note, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith shall determine that the withholding of such notice is in
the interests of the Certificateholders. For the purpose of this Section 7.02 in
respect of any Trust, the term "default" means any event that is, or after
notice or lapse of time or both would become, an Event of Default in respect of
that Trust.

                  Section 7.03. Certain Rights of Trustee. Subject to the
provisions of Section 315 of the Trust Indenture Act:

                  (a) the Trustee may rely and shall be protected in acting or

                  (c) whenever in the administration of this Agreement or the
         Intercreditor Agreement, the Trustee shall deem it desirable that a
         matter be proved or established prior to taking, suffering or omitting
         any action hereunder, the Trustee (unless other evidence be herein
         specifically prescribed) may, in the absence of bad faith on its part,

         Trustee or any related Loan Trustee;

                  (d) the Trustee may consult with counsel and the advice of
         such counsel or any Opinion of Counsel shall be full and complete

         Agreement, unless the Certificateholders shall have offered to the
         Trustee reasonable security or indemnity against the cost, expenses and
         liabilities which might be incurred by it in compliance with such
         Direction;

                  (f) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture or other paper or document;

                  (g) the Trustee may execute any of the trusts or powers under
         this Agreement or any Intercreditor Agreement or perform any duties
         under this Agreement or any Intercreditor Agreement either directly or
         by or through agents or attorneys, and the Trustee shall not be
         responsible for any misconduct or negligence on the part of any agent
         or attorney appointed with due care by it under this Agreement or any
         Intercreditor Agreement;

                  (h) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         Direction of the Certificateholders holding Certificates of any series

         majority in interest in the related Trust relating to the time, method
         and place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Agreement or any Intercreditor Agreement; and

                  (i) the Trustee shall not be required to expend or risk its
         own funds in the performance of any of its duties under this Agreement,
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that repayment of such funds or
         adequate indemnity against such risk is not reasonably assured to it.

         expenses and disbursements of its agents and counsel), except any such
         expense, disbursement or advance as may be attributable to its
         negligence, willful misconduct or bad faith or as may be incurred due
         to the Trustee's breach of its representations and warranties set forth
         in Section 7.15; and

                  (c) to indemnify, or cause to be indemnified, the Trustee with
         respect to the Certificates of any series, pursuant to the particular
         sections of the Note Purchase Agreement specified in the related Trust
         Supplement.

                  The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates of each series upon, all property and
funds held or collected by the Trustee in its capacity as Trustee with respect
to any series or the related Trust for any tax incurred without negligence, bad
faith or willful misconduct, on its part, arising out of or in connection with
the acceptance or administration of the Trust (other than any tax attributable
to the Trustee's compensation for serving as such), including any costs and
expenses incurred in contesting the imposition of any such tax. The Trustee
shall notify the Company of any claim for any tax for which it may seek
reimbursement. If the Trustee reimburses itself from the Trust Property of such
Trust for any such tax, it will mail a brief report within 30 days setting forth
the amount of such tax and the circumstances thereof to all Certificateholders
of such series as their names and addresses appear in the Register.

                  Section 7.08. Corporate Trustee Required; Eligibility. Each
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act and shall have a
combined capital and surplus of at least $75,000,000 (or a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000). If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08 the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

                  In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of any
Trust, the Trustee shall resign immediately as Trustee of such Trust in the
manner and with the effect specified in Section 7.09.

                  Section 7.09. Resignation and Removal, Appointment of
Successor. (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee of any Trust pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee under Section 7.10.

                  (b) The Trustee may resign at any time as Trustee of any or
all Trusts by giving prior written notice thereof to the Company, the Authorized
Agents, the related Owner Trustees and the related Loan Trustees. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Company, the related Owner Trustees and the Trustee within 30 days after the
giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  (c) The Trustee may be removed at any time by Direction of the
Certificateholders of the related series holding Certificates evidencing
Fractional Undivided Interests aggregating not less than a majority in interest
in such Trust delivered to the Trustee and to the Company, the related Owner
Trustees and the related Loan Trustees.

                  (d) If at any time in respect of the Trust:

                   (i) the Trustee shall fail to comply with Section 310 of the
         Trust Indenture Act, if applicable, after written request therefor by
         the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or

                  (ii) the Trustee shall cease to be eligible under Section 7.08
         and shall fail to resign after written request therefor by the Company
         or by any such Certificateholder; or

                 (iii) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
         its property shall be appointed or any public officer shall take charge
         or control of the Trustee or of its property or affairs for the purpose
         of rehabilitation, conservation or liquidation;

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder of the related series who has been a bona fide
Certificateholder for at least six months may, on behalf of itself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee of the Trust.

                                      -42-


                  (e) If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee of
such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax. The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where there
are no Avoidable Taxes. As used herein, an "Avoidable Tax" in respect of such
Trust means a state or local tax: (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of such Trust or (z) the Trustee for which the
Trustee is entitled to seek reimbursement from the Trust Property of such Trust,
and (ii) which would be avoided if the Trustee were located in another state, or
jurisdiction within a state, within the United States of America. A tax shall
not be an Avoidable Tax in respect of any Trust if the Company or any Owner
Trustee shall agree to pay, and shall pay, such tax.

                  (f) If the Trustee shall resign, be removed or become
incapable of acting as Trustee of any Trust or if a vacancy shall occur in the
office of the Trustee of any Trust for any cause, the Company shall promptly
appoint a successor Trustee of such Trust. If, within one year after such
resignation, removal or incapability, or other occurrence of such vacancy, a
successor Trustee of such Trust shall be appointed by Direction of the
Certificateholders of the related series holding Certificates of such series
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in such Trust delivered to the Company, the related Owner Trustees,
the related Loan Trustee and the retiring Trustee, then the successor Trustee so
appointed shall, with the approval of the Company of such appointment, which
approval shall not be unreasonably withheld, forthwith upon its acceptance of
such appointment, become the successor Trustee and supersede the successor
Trustee appointed as provided above. If no successor Trustee shall have been so
appointed as provided above and accepted appointment in the manner hereinafter
provided, the resigning Trustee or any Certificateholder who has been a bona
fide Certificateholder of the related series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                  (g) The successor Trustee shall give notice of the resignation
and removal of the Trustee and appointment of the successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Certificateholders of the related series as their names and addresses appear in
the Register. Each notice shall include the name of such successor Trustee and
the address of its Corporate Trust Office.

                  Section 7.10. Acceptance of Appointment by Successor. Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all Trust Property held by such retiring Trustee in respect of such
Trusts hereunder, subject nevertheless to its lien, if any, provided for in
Section 7.07. Upon request of any such successor Trustee, the Company, the
retiring Trustee and such successor Trustee shall execute and deliver any and
all instruments containing such provisions as shall be necessary or desirable to
transfer and confirm to, and for more fully and certainly vesting in, such
successor Trustee all such rights, powers and trusts.

                  If a successor Trustee is appointed with respect to one or
more (but not all) Trusts, the Company, the predecessor Trustee and each
successor Trustee with respect to any Trust shall execute and deliver a
supplemental agreement hereto which shall contain such provisions as shall be
deemed necessary or desirable to confirm that all the rights, powers, trusts and
duties of the predecessor Trustee with respect to the Trusts as to which the
predecessor Trustee is not retiring shall continue to be vested in the
predecessor Trustee, and shall add to or change any of the provisions of this
Basic Agreement and the applicable Trust Supplements as shall be necessary to
provide for or facilitate the administration of the Trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental agreement shall constitute such Trustees as co-Trustees of the same
Trust and that each such Trustee shall be Trustee of separate Trusts.

                  No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                  Section 7.11. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper or
any further act on the part of any of the parties hereto. In case any
Certificates shall have been executed or authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or consolidation
to such authenticating Trustee may adopt such execution or authentication and
deliver the Certificates so executed or authenticated with the same effect as if
such successor Trustee had itself executed or authenticated such Certificates.

                  Section 7.12. Maintenance of Agencies. (a) With respect to
each series of Certificates, there shall at all times be maintained an office or
agency in the location set forth in Section 12.04 where Certificates of such
series may be presented or surrendered for registration of transfer or for
exchange, and for payment thereof, and where notices and demands, to or upon the
Trustee in respect of such Certificates or this Agreement may be served;
provided, however, that, if it shall be necessary that the Trustee maintain an
office or agency in another location with respect to the Certificates (e.g., the
Certificates of such series shall be represented by Definitive Certificates and
shall be listed on a national securities exchange), the Trustee will make all
reasonable efforts to establish such an office or agency. Written notice of the
location of each such other office or agency and of any change of location
thereof shall be given by the Trustee to the Company, any Owner Trustees, the
Loan Trustees (in the case of any Owner Trustee or Loan Trustee, at its address
specified in the Note Documents or such other address as may be notified to the
Trustee) and the Certificateholders of such series. In the event that no such
office or agency shall be maintained or no such notice of location or of change
of location shall be given, presentations and demands may be made and notices
may be served at the Corporate Trust Office of the Trustee.

                  (b) There shall at all times be a Registrar and a Paying Agent
hereunder with respect to the Certificates of each series. Each such Authorized
Agent shall be a bank or trust company, shall be a corporation organized and
doing business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate trust
powers, subject to supervision by federal or state authorities. The Trustee
shall initially be the Paying Agent and, as provided in Section 3.04, Registrar
hereunder with respect to the Certificates of each series. Each Registrar shall
furnish to the Trustee, at stated intervals of not more than six months, and at
such
<PAGE>   51
                                      -45-


other times as the Trustee may request in writing, a copy of the Register
maintained by such Registrar.

                  (c) Any corporation into which any Authorized Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under this Section
7.12, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

                  (d) Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any related Owner
Trustees and the related Loan Trustees. The Company may, and at the request of
the Trustee shall, at any time terminate the agency of any Authorized Agent by
giving written notice of termination to such Authorized Agent and to the
Trustee. Upon the resignation or termination of an Authorized Agent or in case
at any time any such Authorized Agent shall cease to be eligible under this
Section 7.12 (when, in either case, no other Authorized Agent performing the
functions of such Authorized Agent shall have been appointed), the Company shall
promptly appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 7.12. The Company shall give written notice of
any such appointment made by it to the Trustee, any related Owner Trustees and
the related Loan Trustees; and in each case the Trustee shall mail notice of
such appointment to all Certificateholders of the related series as their names
and addresses appear on the Register for such series.

                  (e) The Company agrees to pay, or cause to be paid, from time
to time to each Authorized Agent reasonable compensation for its services and to
reimburse it for its reasonable expenses.

                  Section 7.13. Money for Certificate Payments to Be Held in
Trust. All moneys deposited with any Paying Agent for the purpose of any payment
on Certificates shall be deposited and held in trust for the benefit of the
Certificateholders entitled to such payment, subject to the provisions of this
Section 7.13. Moneys so deposited and held in trust shall constitute a separate
trust fund for the benefit of the Certificateholders with respect to which such
money was deposited.

                  The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by such Paying Agent; and, upon
<PAGE>   52
                                      -46-


such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

                  Section 7.14. Registration of Equipment Notes in Trustee's
Name. Subject to the provisions of any Intercreditor Agreement, the Trustee
agrees that all Equipment Notes to be purchased by any Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as Trustee for
the applicable Trust or its nominee and held by the Trustee in trust for the
benefit of the Certificateholders of such series, or, if not so held, the
Trustee or its nominee shall be reflected as the owner of such Equipment Notes
or Permitted Investments, as the case may be, in the register of the issuer of
such Equipment Notes or Permitted Investments, as the case may be.

                  Section 7.15. Representations and Warranties of Trustee. The
Trustee hereby represents and warrants that:

                  (a) the Trustee is a Delaware banking corporation organized
         and validly existing in good standing under the laws of the State of
         Delaware;

                  (b) the Trustee has full power, authority and legal right to
         execute, deliver and perform this Agreement, any Intercreditor
         Agreement and the Note Purchase Agreements and has taken all necessary
         action to authorize execution, delivery and performance by it of this
         Agreement, any Intercreditor Agreement and the Note Purchase
         Agreements.

                  (c) the execution, delivery and performance by the Trustee of
         this Agreement, any Intercreditor Agreement and the Note Purchase
         Agreements (i) will not violate any provision of any United States
         federal law or the law of the state of the United States where it is
         located governing the banking and trust powers of the Trustee or any
         order, writ, judgment, or decree of any court, arbitrator or
         governmental authority applicable to the Trustee or any of its assets,
         (ii) will not violate any provision of the articles of association or
         by-laws of the Trustee, and (iii) will not violate any provision of, or
         constitute, with or without notice or lapse of time, a default under,
         or result in the creation or imposition of any lien on any properties
         included in the Trust Property pursuant to the provisions of any
         mortgage, indenture, contract, agreement or other undertaking to which
         it is a party, which violation, default or lien could reasonably be
         expected to have an adverse effect on the Trustee's performance or
         ability to perform its duties hereunder or thereunder or on the
         transactions contemplated herein or therein;

                  (d) the execution, delivery and performance by the Trustee of
         this Agreement, any Intercreditor Agreement and the Note Purchase
         Agreements will not require the authorization, consent, or approval of,
         the giving of notice to, the filing or registration
<PAGE>   53
                                      -47-


         with, or the taking of any other action in respect of, any governmental
         authority or agency of the United States or the state of the United
         States where it is located regulating the banking and corporate trust
         activities of the Trustee; and

                  (e) this Agreement, any Intercreditor Agreement and the Note
         Purchase Agreements have been duly executed and delivered by the
         Trustee and constitute the legal, valid and binding agreements of the
         Trustee, enforceable against it in accordance with their respective
         terms; provided, however, that enforceability may be limited by (i)
         applicable bankruptcy, insolvency, reorganization, moratorium or
         similar laws affecting the rights of creditors generally and (ii)
         general principles of equity.

                  Section 7.16. Withholding Taxes: Information Reporting. As to
the Certificates of any series, the Trustee, as trustee of the related grantor
trust created by this Agreement, shall exclude and withhold from each
distribution of principal, premium, if any, and interest and other amounts due
under this Agreement or under the Certificates of such series any and all
withholding taxes applicable thereto as required by law. The Trustee agrees to
act as such withholding agent and, in connection therewith, whenever any present
or future taxes or similar charges are required to be withheld with respect to
any amounts payable in respect of the Certificates, to withhold such amounts and
timely pay the same to the appropriate authority in the name of and on behalf of
the Certificateholders of such series, that it will file any necessary
withholding tax returns or statements when due, and that, as promptly as
possible after the payment thereof, it will deliver to each such
Certificateholder of such series, appropriate documentation showing the payment
thereof, together with such additional documentary evidence as such
Certificateholders may reasonably request from time to time. The Trustee agrees
to file any other information reports as it may be required to file under United
States law.

                  Section 7.17. Trustee's Liens. The Trustee in its individual
capacity agrees that it will, in respect of each Trust created by this
Agreement, at its own cost and expense promptly take any action as may be
necessary to duly discharge and satisfy in full any mortgage, pledge, lien,
charge, encumbrance, security interest or claim ("Trustee's Liens") on or with
respect to the Trust Property of such Trust which is attributable to the Trustee
either (i) in its individual capacity and which is unrelated to the transactions
contemplated by this Agreement or the related Note Documents or (ii) as Trustee
hereunder or in its individual capacity and which arises out of acts or
omissions which are not contemplated by this Agreement.

                  Section 7.18. Preferential Collection of Claims. The Trustee
shall comply with Section 311(a) of the Trust Indenture Act, excluding any

         Agreement, any Intercreditor Agreement or any Liquidity Facility
         (including any supplemental agreement) under the Trust Indenture Act or

                  (i) to make any other amendments or modifications hereto,
         provided, however, that such amendments or modifications shall apply to

in such Trust, by Direction of said Certificateholders delivered to the Company
and the Trustee, the Company may (with the consent of the Owner Trustees, if

         Certificate of such series, or change the place of payment where, or

                  (b) permit the disposition of any Equipment Note included in

         provided for in this Agreement; or

         federal income tax purposes.

                  It shall not be necessary for any Direction of such

                                    ARTICLE X

                   AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS


                  Section 10.01. Amendments and Supplements to Indenture and
Other Note Documents. In the event that the Trustee, as holder (or beneficial
owner through the Subordination Agent) of any Equipment Notes (or as a
prospective purchaser of any Postponed Notes) in trust for the benefit of the
Certificateholders of any series or as Controlling Party under an Intercreditor
Agreement, receives (directly or indirectly through the Subordination Agent) a
request for a consent to any amendment, modification, waiver or supplement under
any Indenture, other Note Document or any other related document, which request
would require the consent of Certificateholders of any series under Section 9.02
hereof, the Trustee shall forthwith send a notice of such proposed amendment,
modification, waiver or supplement to each Certificateholder of such series
registered on the Register as of the date of such notice. The Trustee shall
request from the Certificateholders of such series a Direction as to (a) whether
or not to take or refrain from taking (or direct the Subordination Agent to take
or refrain from taking) any action which a holder of (or, with respect to
Postponed Notes, a prospective purchaser of) such Equipment Note the option to
direct, (b) whether or not to give or execute (or direct the Subordination Agent
to give or execute) any waivers, consents, amendments, modifications or
supplements as a holder of (or, with respect to Postponed Notes, a prospective
purchaser of) such Equipment Note or as Controlling Party and (c) how to vote
(or direct the Subordination Agent to vote) any Equipment Note (or, with respect
to a Postponed Note, its commitment to acquire such Postponed Note) if a vote
has been called for with respect thereto. Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment
<PAGE>   60
                                      -54-


Note (or in directing the Subordination Agent in any of the foregoing), (i)
other than as Controlling Party, the Trustee shall vote for or give consent to
any such action with respect to such Equipment Note (or Postponed Note) in the
same proportion as that of (A) the aggregate face amounts of all Certificates
actually voted in favor of or for giving consent to such action by such
Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders of
such series evidencing a Fractional Undivided Interest aggregating not less than
a majority in interest in the Trust. For purposes of the immediately preceding
sentence, a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent. Notwithstanding the
foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the
Trustee may, with respect to the Certificates of any series, in its own
discretion and at its own direction, consent and notify the relevant Loan
Trustee of such consent (or direct the Subordination Agent to consent and notify
the Loan Trustee of such consent) to any amendment, modification, waiver or
supplement under any related Indenture or any other related Note Document if an
Event of Default hereunder shall have occurred and be continuing or if such
amendment, modification, waiver or supplement will not materially adversely
affect the interests of the Certificateholders of such series.


                                   ARTICLE XI

                              TERMINATION OF TRUSTS


                  Section 11.01. Termination of the Trusts. In respect of each
Trust created by the Basic Agreement as supplemented by a related Trust
Supplement, the respective obligations and responsibilities of the Company and
the Trustee with respect to such Trust shall terminate upon the distribution to
all Holders of Certificates of the series of such Trust and the Trustee of all
amounts required to be distributed to them pursuant to this Agreement and the
disposition of all property held as part of the Trust Property of such Trust;
provided, however, that in no event shall the Trust continue beyond one hundred
ten (110) years following the date of the execution of the Trust Supplement with
respect to such Trust (or such other final expiration date as may be specified
in such Trust Supplement).

                  Notice of any termination of a Trust, specifying the
applicable Regular Distribution Date (or the applicable Special Distribution
Date, as the case may be) upon which the Certificateholders of any series may
surrender their Certificates to the Trustee for payment of the final
distribution and cancellation, shall be mailed promptly by the Trustee to
Certificateholders of such series not earlier than the minimum of days and not
later than the maximum number of days specified therefor in the related Trust
Supplement preceding such final distri-
<PAGE>   61
                                      -55-


bution specifying (A) the Regular Distribution Date (or Special Distribution
Date, as the case may be) upon which the proposed final payment of the
Certificates of such series will be made upon presentation and surrender of
Certificates of such series at the office or agency of the Trustee therein
specified, (B) the amount of any such proposed final payment, and (C) that the
Record Date otherwise applicable to such Regular Distribution Date (or Special
Distribution Date, as the case may be) is not applicable, payments being made
only upon presentation and surrender of the Certificates of such series at the
office or agency of the Trustee therein specified. The Trustee shall give such
notice to the Registrar at the time such notice is given to Certificateholders
of such series. Upon presentation and surrender of the Certificates of such
series in accordance with such notice, the Trustee shall cause to be distributed
to Certificateholders of such series amounts distributable on such Regular
Distribution Date (or Special Distribution Date, as the case may be) pursuant to
Section 4.02.

                  In the event that all of the Certificateholders of such series
shall not surrender their Certificates for cancellation within six months after
the date specified in the above-mentioned written notice, the Trustee shall give
a second written notice to the remaining Certificateholders of such series to
surrender their Certificates for cancellation and receive the final distribution
with respect thereto. No additional interest shall accrue on the Certificates of
such series after any Regular Distribution Date (or Special Distribution Date,
as the case may be) of such series, as specified in the first written notice. In
the event that any money held by the Trustee for the payment of distributions on
the Certificates of such series shall remain unclaimed for two years (or such
lesser time as the Trustee shall be satisfied, after 60 days' notice from the
Company, is one month prior to the escheat period provided under applicable law)
after the final distribution date with respect thereto, the Trustee shall pay to
each Loan Trustee the appropriate amount of money relating to such Loan Trustee
and shall give written notice thereof to the related Owner Trustees, the Owner
Participants and the Company.


                                   ARTICLE XII

                            MISCELLANEOUS PROVISIONS


                  Section 12.01. Limitation on Rights of Certificateholders. The
death or incapacity of any Certificateholder of any series shall not operate to
terminate this Agreement or the related Trust, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or commence any proceeding in any court for a partition or
winding up of the Trust, nor otherwise affect the rights, obligations, and
liabilities of the parties hereto or any of them.

                  Section 12.02. Liabilities of Certificateholders. Neither the
existence of the Trust nor any provision in this Agreement is intended to or
shall limit the liability the Certificateholders would otherwise incur if the
Certificateholders owned Trust Property as co-owners, or incurred any
obligations of the Trust, directly rather than through the Trust.

                  Section 12.03. Registration of Equipment Notes in Name of
Subordination Agent. If the Trust is party to an Intercreditor Agreement, the
Trustee agrees that all Equipment Notes to be purchased by such Trust shall be
issued in the name of the Subordination Agent under such Intercreditor Agreement
or its nominee and held by such Subordination Agent in trust for the benefit of
the Certificateholders, or, if not so held, such Subordination Agent or its
nominee shall be reflected as the owner of such Equipment Notes in the register
of the issuer of such Equipment Notes.

                  Section 12.04. Notices. (a) Unless otherwise specifically
provided herein or in the applicable Trust Supplement, all notices required
under the terms and provisions of this Basic Agreement or such Trust Supplement
shall be in English and in writing, and any such notice may be given by United
States mail, courier service or telecopy, and any such notice shall be effective

of the covenants, agreements, provisions or terms of this Agreement shall be for
any reason whatsoever held invalid, then such covenants, agreements, provisions,

or of the Certificates of such series or the rights of the Certificateholders
thereof.

1999 (the "Basic Agreement"), as supplemented by Trust Supplement No. ___
thereto dated ___, 1999 (collectively, the "Agreement"), between the Trustee and
Atlas Air, Inc., a corporation incorporated under Delaware law (the "Company"),
a summary of certain of the pertinent provisions of which is set forth below. To
the extent not otherwise defined herein, the capitalized terms used herein have
the meanings assigned to them in the Agreement. This Certificate is one of the
duly authorized Certificates designated as "___% Atlas Air Pass Through
Certificate, Series ___" (herein called the "Certificates"). This Certificate is
issued under and is subject to the terms, provisions and conditions of the
Agreement. By virtue of its acceptance hereof, the Certificateholder of this
Certificate assents to and agrees to be bound by the provisions of the Agreement
and any related Intercreditor Agreement. The property of the Trust includes
certain Equipment Notes and all rights of the Trust to receive any payments
under any Intercreditor Agreement or Liquidity Facility (the "Trust Property").
Each issue of the Equipment Notes is or will be secured by, among other things,
a security interest in aircraft leased to or owned by the Company.

                  The Certificates represent fractional undivided interests in
the Trust and the Trust Property, and have no rights, benefits or interest in
respect of any other separate trust established pursuant to the terms of the
Basic Agreement for any other series of certificates issued pursuant thereto.

                  Subject to and in accordance with the terms of the Agreement
and any related Intercreditor Agreement, from funds then available to the
Trustee, there will be distributed on each ___________ and ___________ (a
"Regular Distribution Date"), commencing on ___________, ____, to the Person in
whose name this Certificate is registered at the close of business on the 15th
day preceding the Regular Distribution Date, an amount in respect of the
Scheduled Payments on the Equipment Notes due on such Regular Distribution Date,
the receipt of which has been confirmed by the Trustee, equal to the product of
the percentage interest in the Trust evidenced by this Certificate and an amount
equal to the sum of such Scheduled Payments. Subject to and in accordance with
the terms of the Agreement and any related Intercreditor Agreement , in the
event that Special Payments on the Equipment Notes are received by the Trustee,
from funds then available to the Trustee, there shall be distributed on the
applicable Special Distribution Date, to the Person in whose name this
Certificate is registered at the close of business on the 15th day preceding the
Special Distribution Date, an amount in respect of such Special Payments on the
Equipment Notes, the receipt of which has been confirmed by the Trustee, equal
to the product of the percentage interest in the Trust evidenced by this
Certificate and an amount equal to the sum of such Special Payments so received.
If a Regular Distribution Date or Special Distribution Date is not a Business
Day, distribution shall be made on the immediately following Business Day with
the same force and effect as if made on such Regular Distribution Date or
Special Distribution Date and no interest shall accrue during the intervening
period. The Trustee shall mail notice of each Spe-

                                      -62-


cial Payment and the Special Distribution Date therefor to the Certificateholder
of this Certificate.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the Person entitled thereto, without the presentation or
surrender of this Certificate or the making of any notation hereon. Except as
otherwise provided in the Agreement and notwithstanding the above, the final
distribution on this Certificate will be made after notice mailed by the Trustee
of the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency of the Trustee specified in such
notice.

                  The Certificates do not represent a direct obligation of, or
an obligation guaranteed by, or an interest in, the Company or the Trustee or
any affiliate thereof. The Certificates are limited in right of payment, all as
more specifically set forth on the face hereof and in the Agreement. All
payments or distributions made to Certificateholders under the Agreement shall
be made only from the Trust Property and only to the extent that the Trustee
shall have sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of the Agreement. Each Certificateholder
of this Certificate, by its acceptance hereof, agrees that it will look solely
to the income and proceeds from the Trust Property to the extent available for
distribution to such Certificateholder as provided in the Agreement. This
Certificate does not purport to summarize the Agreement and reference is made to
the Agreement for information with respect to the interests, rights, benefits,
obligations, proceeds, and duties evidenced hereby. A copy of the Agreement may
be examined during normal business hours at the principal office of the Trustee,
and at such other places, if any, designated by the Trustee, by any
Certificateholder upon request.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Certificateholders under the
Agreement at any time by the Company and the Trustee with the consent of the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Trust. Any
such consent by the Certificateholder of this Certificate shall be conclusive
and binding on such Certificateholder and upon all future Certificateholders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Certificateholders of
any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations set forth, the transfer of this Certificate is registrable in the
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Trustee in its capacity as Registrar, or
by any successor Registrar duly endorsed or accompanied by a written instrument
<PAGE>   69
                                      -63-


of transfer in form satisfactory to the Trustee and the Registrar, duly executed
by the Certificateholder hereof or such Certificateholder's attorney duly
authorized in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in the
Trust will be issued to the designated transferees or transferees.

                  The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of $1,000 Fractional Undivided Interest
and integral multiples thereof except that one Certificate may be issued in a
different denomination. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of authorized denominations evidencing the same aggregate
Fractional Undivided Interest in the Trust, as requested by the
Certificateholder surrendering the same.

                  No service charge will be made for any such registration or
transfer or exchange, but the Trustee shall require payment of a sum sufficient
to cover any tax or governmental charge payable in connection therewith.

                  The Trustee, the Registrar, and any agent of the Trustee or
the Registrar may treat the person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Trustee, the Registrar,
nor any such agent shall be affected by any notice to the contrary.

                  The obligations and responsibilities created by the Agreement
and the Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant to
the Agreement and the disposition of all property held as part of the Trust
Property.

                  THIS CERTIFICATE AND THE AGREEMENT HAVE EACH BEEN DELIVERED IN
THE STATE OF NEW YORK AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES AND
CERTIFICATEHOLDERS HEREUNDER AND THEREUNDER SHALL BE DETERMINED IN ACCORDANCE
WITH SUCH LAWS.

be duly executed.

Section 1.03.     Form of Documents Delivered to Trustee.

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

Section 1.04.     Acts of Holders; Record Dates.

                  (a) Any request, demand,, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. 
<PAGE>   17
                                      -10-


Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this Indenture and (subject to
Section 6.01) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

                  Without limiting the generality of the foregoing, a Holder,
including a Depositary that is a Holder of a Global Security, may make, give or
take, by a proxy, or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be made, given or taken by Holders, and a Depositary that is a
Holder of a Global Security may provide its proxy or proxies to the beneficial
owners of interests in any such Global Security.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

                  (c) The Company may fix any day as the record date for the
purpose of determining the Holders of Securities of any series entitled to give
or take any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or taken by
Holders of Securities of such series, other than any such action provided or
permitted to be taken under Section 5.01, 5.02 or 5.12. Such record date shall
be not earlier than the 30th day prior to the first solicitation of any Holder
to give or take any such action and not later than the date of such first
solicitation. With regard to any record date for action to be taken by the
Holders of one or more series of Securities, only the Holders of Securities of
such series on such date (or their duly designated proxies) shall be entitled to
give or take the relevant action. The Company shall notify the Trustee in
writing of any such record date not later than the date of the first
solicitation of any Holder to give or take any action.

                  (d) The ownership of Securities shall be proved by the
Security Register.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

Section 1.05.     Notices, Etc., to Trustee and Comipany.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trust Department, or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument, to the
         attention of its Treasurer, with a separate copy to its General Counsel
         (provided that the failure of any Holder to send a separate copy shall
         not affect the sufficiency of the notice), or at any other address
         previously furnished in writing to the Trustee by the Company.

Section 1.06.     Notice to Holders; Waiver.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any 
<PAGE>   19
                                      -12-


notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

Section 1.07.     Conflict with Trust Indenture Act.

                  If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

Section 1.08.     Effect of Headings and Table of Contents.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

Section 1.09.     Successors and Assigns.

                  All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.

Section 1.10.     Separability Clause.

                  In case any provision in this Indenture or in the Securities
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

Section 1.11.     Benefits of Indenture.

                  Nothing in this Indenture or in the Securities, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder and the Holders, any benefit or any legal or equitable
right, remedy or claim under this Indenture. Section 1.12. Governing Law.

                  This Indenture and the Securities shall be governed by and
construed in accordance with the laws of the State of New York.

Section 1.13.     Legal Holidays.

                  In any case where any Interest Payment Date, Redemption Date
or Stated Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of the Securities of any series which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, provided
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

form set forth in this Article, or in such other form as shall be established by

a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 3.03 for the authentication and delivery of such
Securities.

                  The definitive Securities shall be printed, lithographed or

as determined by the officers executing such Securities, as evidenced by their
execution of such Securities.

percentages in principal amount of the Securities of each series at the time

compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu

such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default, the Holders of not less than 25% in principal
amount of the Outstanding Securities shall have made written request, and
offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee, and the Trustee shall not have received from the Holders of a majority

have failed to institute such proceedings within 60 days; provided, however,
that such limitations do not apply to a suit instituted by the Holder hereof for
the enforcement of payment of the principal of (and premium, if any) or any
interest on this Security on or after the respective due dates expressed herein.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the

<PAGE>   33
                                      -26-


determined in the manner provided, in the officers' Certificate referred to

                  If any of the terms of the series are established by action
taken pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of the series.

Section 3.02.     Denominations.

                  Unless otherwise specified as contemplated by Section 3.01,
the Securities of each series shall be issuable only in registered form without
coupons in such denominations as shall be specified as contemplated by Section
3.01. In the absence of any such specification with respect to the Securities of
any series, the Securities of such series shall be issuable in denominations of
$1,000 and any integral multiple thereof.

Section 3.03.     Execution, Authentication, Delivery and Dating.

                  The Securities shall be executed on behalf of the Company by
its Chairman of the Board, its President or one of its Vice Presidents, under
its corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

                  Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any Series
executed by the Company to the Trustee for authentication, together with a
Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.01 and 3.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Secu-
<PAGE>   34
                                      -27-


rities, the Trustee shall be entitled to receive, and (subject to Section 6.01)
shall be fully protected in relying upon, an Opinion of Counsel stating,

                  (a) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 2.01, that such
         form has been established in conformity with the provisions of this
         Indenture;

                  (b) if the terms of such Securities have been established by
         or pursuant to Board Resolution as permitted by Section 3.01, that such
         terms have been established in conformity with the provisions of this
         Indenture; and

                  (c) that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

                  If such form or terms have been so established, the Trustee
shall not be required to authenticate such Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee.

                  Notwithstanding the provisions of Section 3.01 and of the
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.01 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraph at or
prior to the time of authentication of each Security of such series if such
documents are delivered at or prior to the authentication upon original issuance
of the first Security of such series to be issued.

                  Each Security shall be dated the date of its authentication.

                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication 
<PAGE>   35
                                      -28-


substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder.

Section 3.04.     Temporary Securities.

                  Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

                  If temporary Securities of any series are issued, the Company
will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for
that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and tenor. Until so exchanged the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

Section 3.05.     Registration, Registration of Transfer and Exchange. 

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and of transfers of Securities. The Trustee
is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers 
<PAGE>   36
                                      -29-


of Securities as herein provided; provided that the Company may, from time to
time, designate (or change any designation of) any other Person or Persons to
act as Security Registrar or co-Security Registrars with respect to the
Securities of one or more series, with notice to the Trustee and as provided in
Section 1.06 to the Holders. At all reasonable times the Security Register shall
be open for inspection by the Company. In the event that the Trustee shall not
be the Security Registrar, it shall have the right to examine the Security
Register at all reasonable times. At all reasonable times the Security Register
shall be open for inspection by the Company. In the event that the Trustee shall
not be the Security Registrar, it shall have the right to examine the Security
Register at all reasonable times.

                  Upon surrender for registration of transfer of any Security of
any series at the office or agency in a Place of Payment for that series,, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount and tenor.

                  At the option of the Holder, Securities of any series may be
exchanged for other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Securities to be exchanged at such office or agency. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

                  All Securities issued upon any registration of transfer or
exchange of securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other 
<PAGE>   37
                                      -30-


governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
3.04, 9.06 or 11.07 not involving any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
11.03 and ending at the close of business on the day of such mailing, or (ii) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

                  Notwithstanding the foregoing, no Global Security shall be
registered for transfer or exchange, or authenticated and delivered, whether
pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or otherwise, in the
name of a Person other than the Depositary for such Global Security or its
nominee until (i) the Depositary with respect to a Global Security notifies the
Company that it is unwilling or unable to continue as Depositary for such Global
Security or the Depositary ceases to be a clearing agency registered under the
Exchange Act, (ii) the Company executes and delivers to the Trustee a Company
Order that such Global Security shall be so transferable and exchangeable or
(iii) there shall have occurred and be continuing an Event of Default, or any
event which after notice or lapse of time, or both, would constitute an Event of
Default, with respect to the Securities of such series. Upon the occurrence in
respect of any Global Security of any series of any one or more of the
conditions specified in clauses (i), (ii), (iii) of the preceding sentence or
such other conditions as may be specified as contemplated by Section 3.01 for
such series, such Global Security may be registered for transfer or exchange for
Securities registered in the names of, or authenticated and delivered to, such
Persons as the Depositary with respect to such series shall direct.

                  Except as provided in the preceding paragraph, any Security
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, any Global Security, whether pursuant to this Section,
Section 3.04, 3.06, 9.06 or 11.07 or otherwise, shall also be a Global Security
and bear the legend specified in Section 2.04.

Section 3.06.     Mutilated, Destroyed, Lost and Stolen Securities. 

                  If any mutilated Security is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company and the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
                  Every new Security of any series issued pursuant to this
Section in lieu of any mutilated, destroyed, lost or stolen Security shall
constitute an original additional contractual obligation of the Company, whether
or not the mutilated, destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.07.     Payment of Interest; Interest Rights Preserved.   

                  Except as otherwise provided as contemplated by Section 3.01
with respect to any series of Securities, interest on any Security which is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more

(herein called "Defaulted Interest") shall forthwith cease to be payable to the
Holder on the relevant Regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

                    (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series

         Defaulted Interest, which shall be fixed in the following manner. The
         Company shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security of such series and the

         deposit with the Trustee an amount of money equal to the aggregate
         amount proposed to be paid in respect of such Defaulted Interest or
         shall make arrangements satisfactory to the Trustee for such deposit
         prior to the date of the proposed payment, such money when deposited to
         be held in trust for the benefit of the Persons entitled to such
         Defaulted Interest as in this Clause provided. Thereupon the Trustee
         shall fix a Special Record Date for the payment of such Defaulted
         Interest which shall be not more than 15 days and not less than 10 days
         prior to the date of the proposed payment and not less than 10 days
         after the receipt by the Trustee of the notice of the proposed payment.
         The Trustee shall promptly notify the Company of such Special Record
         Date and, in the name and at the expense of the Company, shall cause
         notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor to be mailed, first class postage prepaid,
         to each Holder of Securities of such series at such Holder's address as
         it appears in the Security Register, not less than 10 days 
<PAGE>   40
                                      -33-


         prior to such Special Record Date. Notice of the proposed Payment of
         such Defaulted Interest and the Special Record Date therefor having
         been so mailed, such Defaulted Interest shall be paid to the Persons in
         whose names the Securities of such series (or their respective
         Predecessor Securities) are registered at the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following Clause (2).

                    (2) The Company may make payment of any Defaulted Interest
         on the Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Securities may be listed, and upon such notice as may be required
         by such exchange, if, after notice given by the Company to the Trustee
         of the proposed payment pursuant to this Clause, such manner of payment
         shall be deemed practicable by the Trustee.

                  Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

                  (8) any other Event of Default provided with respect to
         Securities of that series.

Section 5.02. Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in principal
amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if
<PAGE>   46
                                      -39-


                  (1) the Company has paid or deposited with the Trustee a sum
         sufficient to pay

                      (A) all overdue interest on all Securities of that series,

                      (B) the principal of (and premium, if any, on) any
                  Securities of that series which have become due otherwise than
                  by such declaration of acceleration and any interest thereon
                  at the rate or rates prescribed therefor in such Securities,

                      (C) to the extent that payment of such interest is lawful,
                  interest upon overdue interest at the rate or rates prescribed
                  therefor in such Securities, and

                      (D) all sums paid or advanced by the Trustee hereunder and

                  advances of the Trustee, its agents and counsel;

                  and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 5.13.

                  No such rescission shall affect any subsequent default or
impair any right consequent thereon.

Section 5.03. Collection of Indebtedness and Suits for Enforcement by Trustee.

                  The Company covenants that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof and such
         default continues for a period of 5 Business Days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount
<PAGE>   47
                                      -40-


then due and payable on such Securities for principal and any premium and
interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal and premium and on any overdue
interest, at the rate or rates prescribed therefor in such Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

Section 5.04. Trustee May File Proofs of Claim.

                  In case of any judicial proceeding relative to the Company (or
any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other Property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
6.07.

                  No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding;
provided, however, the Trustee may vote on behalf of

may be a member of a creditors or other similar committee.

Section 5.05. Trustee May Enforce Claims Without Possession of Securities.

                  All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

Section 5.06. Application of Money Collected.

                  Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
or any premium or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 6.07;

                  SECOND: To the payment of the amounts then due and unpaid for

         amounts due and payable on such Securities for principal and any
         premium and interest, respectively; and

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto.

Section 5.07. Limitation on Suits.

                  No Holder of any Security of any series shall have any right
to institute any proceeding, judicial or otherwise,
<PAGE>   49
                                      -42-


with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of that series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of

time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

                                      -44-


                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

series and its consequences, except a default

                  (1) in the payment of the principal of or any premium or
         interest on any Security of such series, or

         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

                  Upon any such waiver, such default shall cease to exist, and

every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

Section 5.14. Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
in the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company,
by any Holder, or group of Holders, holding in the aggregate more than 10% in
principal amount of the Outstanding Securities, or by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest

covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage of

by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,

payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the

adversely affect the Company's ability to perform its obligations under this
Indenture.

         Securities to be redeemed,

                  (4) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and, if
         applicable, that interest thereon will cease to accrue on and after
         said date,

accrued interest) such Securities shall cease to bear interest. Upon Surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest to the Redemption Date; provided, however, that, unless

until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

without service charge, a new Security or Securities of the same series and of

                  Re: Registration of Common Stock

Ladies and Gentlemen:

                  We have acted as counsel for Atlas Air, Inc., a Delaware
corporation ("Atlas"), in connection with the filing by Atlas of its
Registration Statement on Form S-3 (the "Registration Statement") under the
Securities Act of 1933, which registration statement relates to up to
$650,000,000 in aggregate principal amount of certain shares of Common Stock of
Atlas, $0.01 par value per share (the "Common Stock").

                  In so acting, we have examined and relied upon the accuracy of
original, certified, conformed or photographic copies of such records,
agreements, certificates and other documents as we have deemed necessary or
appropriate to enable us to render the opinions set forth below. In all such
examinations, we have assumed the genuineness of signatures on original
documents and the conformity to such original documents of all copies submitted
to us as certified, conformed or photographic copies and, as to certificates of
public officials and officers of Atlas, we have assumed the same to have been
properly given and to be accurate.

                  Based upon the foregoing, we are of the opinion that the
Common Stock, will be validly issued, fully paid and nonassessable when, as and
if (i) the Registration Statement shall have become effective pursuant to the
provisions of the Act, (ii) appropriate corpo-
<PAGE>   2
                                      -2-


rate action shall have been taken to authorize the issuance and sale of such
Common Stock, (iii) a Prospectus Supplement or Prospectus Supplements with
respect to the shares of Common Stock shall have been filed (or transmitted for
filing) with the Commission pursuant to Rule 424(b) of the Act and any exhibits
necessary under the rules and regulations of the Commission shall have been
filed with the Commission in an amendment to the Registration Statement or
incorporated by reference into the Registration Statement pursuant to a Current
Report on Form 8-K of the Company filed with the Commission, (iv) any legally
required consents, approvals, authorizations and other orders of the Commission
and any other regulatory authorities shall have been obtained and (v)
appropriate certificates representing the shares of Common Stock are duly
executed, countersigned by the Company's transfer agent/registrar, registered
and delivered against payment of the agreed consideration therefore in
accordance with the applicable Agreement.

                  The opinions expressed herein are limited in all respects to
the laws of the State of New York, the corporate laws of the State of Delaware
and the federal laws of the United States.

                  We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Validity of
the Common Stock" in the prospectus relating to the Common Stock that
constitutes a part of the Registration Statement.

                         Re:     Registration of Debt Securities

Ladies and Gentlemen:

                  We have acted as counsel for Atlas Air, Inc., a Delaware
corporation ("Atlas"), in connection with the filing by Atlas of its
Registration Statement on Form S-3 (the "Registration Statement") under the
Securities Act of 1933, which registration statement relates to up to
$650,000,000 in aggregate principal amount of certain debt securities of Atlas
(the "Debt Securities"). The Debt Securities are to be issued by Atlas in one or
more series pursuant to an Indenture to be entered into between Atlas and State
Street Bank and Trust Company (the "Trustee"), a form of which has been filed as
an exhibit to the Registration Statement.

                  In so acting, we have examined and relied upon the accuracy of
original, certified, conformed or photographic copies of such records,
agreements, certificates and other documents as we have deemed necessary or
appropriate to enable us to render the opinions set forth below. In all such
examinations, we have assumed the genuineness of signatures on original
documents and the conformity to such original documents of all copies submitted

                                      -2-

                  Based upon the foregoing, we are of the opinion that the Debt
Securities, when the final terms and provisions thereof have been duly
established and when duly executed on behalf of Atlas, authenticated by the
Trustee under the Indenture and sold by Atlas, will be validly issued, will
constitute valid and binding obligations of Atlas in accordance with their terms
and will be entitled to the benefits of the Indenture in accordance with their
terms and the terms of the Indenture.

                  The opinions set forth above are subject, as to enforcement,
to the effect of (i) any bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the rights and remedies of creditors generally,
(ii) general principles of equity (whether applied by a court of law or equity),
and (iii) requirements that a claim with respect to any Debt Securities
denominated other than in United States dollars (or a foreign currency or
composite currency judgment in respect of such claim) be converted into United
States dollars at a rate of exchange prevailing on a date determined pursuant to
applicable law.

                  The opinions expressed herein are limited in all respects to
the laws of the State of New York, the corporate laws of the State of Delaware
and the federal laws of the United States.

                  We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Validity of
the Debt Securities" in the prospectus relating to the Debt Securities that
constitutes a part of the Registration Statement.

                         Re:     Registration of Pass Through Certificates

Ladies and Gentlemen:

                  We have acted as counsel for Atlas Air, Inc., a Delaware
corporation ("Atlas"), in connection with the filing by Atlas of its
Registration Statement on Form S-3 (the "Registration Statement") under the
Securities Act of 1933, which registration statement relates to up to
$650,000,000 in aggregate principal amount of Pass Through Certificates of Atlas
(the "Pass Through Certificates"). The Pass Through Certificates will be issued
pursuant to the provisions of the Pass Through Trust Agreement to be entered
into between Atlas and Wilmington Trust Company, as Pass Through Trustee (the
"Pass Through Trustee"), a form which has been filed as an exhibit to the
Registration Statement (the "Pass Through Agreement"), as supplemented by a
separate Series Supplement for each series of Pass Through Certificates (each, a
"Series Supplement").

                  In so acting, we have examined and relied upon the accuracy of
original, certified, conformed or photographic copies of such records,
agreements, certificates and other documents as we have deemed necessary or
appropriate to enable us to render the opinions set forth below. In all such

officers of Atlas, we have assumed the same to have been properly given and to
be accurate.

                  Based upon the foregoing, we are of the opinion that, assuming
(i) the due authorization, execution and delivery of the Pass Through Agreement
and each applicable Series Supplement by each of the parties thereto, (ii) the
due authorization, execution, issue, delivery and authentication by the Pass
Through Trustee of the Pass Through Certificates to be issued under the Pass
Through Agreement and each applicable Series Supplement, (A) the Pass Through
Agreement constitutes, and each applicable Series Supplement, when duly executed
and delivered, will constitute, a valid and binding agreement of each of the
parties thereto, and (B) the Pass Through Certificates, when duly executed,
delivered and authenticated by the Pass Through Trustee in accordance with the
terms of the Pass Through Agreement and each applicable Series Supplement and
sold in accordance with the related purchase agreement or underwriting agreement
between Atlas and the purchasers or underwriters, as the case may be, named
therein, will be validly issued, will constitute valid and binding obligations
of the Pass Through Trustee in accordance with their terms and will be entitled
to the benefits of the Pass Through Agreement and each applicable Series
Supplement in accordance with their terms and the terms of the Pass Through
Agreement and such Series Supplement.

                  The opinions set forth above are subject, as to enforcement,
to the effect of (i) bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting the rights and remedies of creditors generally and (ii)

the laws of the State of New York, the corporate laws of the State of Delaware

Registration Statement and to the references to us under the caption "Validity
of the Certificates" and "Certain United States Federal Income Tax Consequences"

                    number of shares of Common Stock held by them respectively.

                    (3) Except as may otherwise be required by law or by the
                    provisions of such resolution or resolutions as may be
                    adopted by the Board of Directors pursuant to section (b) of
                    this Article FOURTH, each holder of Common Stock shall have
                    one vote in respect of each share of Common Stock held on
                    all matters voted upon by the stockholders.

            (d) No holder of any of the shares of any class or series of stock
            or of options, warrants or other rights to purchase shares of any

            shall have any preemptive right to purchase or subscribe for any
            unissued stock of any class or series or any additional shares of
            any class or series to be issued by reason of any increase of the
            authorized capital stock of the Corporation of any class or series,
            or bonds, certificates of indebtedness, debentures or other
            securities convertible into or exchangeable for stock of the
            Corporation of any class or series, or carrying any right to

            stock or securities convertible into or exchangeable for stock, or
            carrying any right to purchase stock, may be issued and disposed of
            pursuant to resolution of the Board of Directors to such persons,
            firms, corporations or associations, whether such holders or others,
            and upon such terms as may be deemed advisable by the Board of
            Directors in the exercise of its sole discretion.

            (e) The relative powers, preferences and rights of each series of
            Preferred Stock in relation to the relative powers, preferences and
            rights of each other series of Preferred Stock shall, in each case,
            be as fixed from time to time by the Board of Directors in the
            resolution or resolutions adopted pursuant to authority granted in
            section (b) of this Article FOURTH and the consent, by class or
            series vote or otherwise, of the holders of such of the series of
            Preferred Stock as are from time to time outstanding shall not be
            required for the issuance by the Board of Directors of any other
            series of Preferred Stock whether or not the powers, preferences and
            rights of such other series shall be fixed by the Board of Directors
            as senior to, or on a parity with, the powers, preferences and
            rights of such outstanding series, or any of them; provided,
            however, that the Board of Directors may provide in the resolution
            or resolutions as to any series of Preferred Stock adopted pursuant
            to section (b) of this Article FOURTH that the consent of the
            holders of a majority (or such greater proportion as shall be
            therein fixed) of the outstanding shares of such series voting
            thereon shall be required for the issuance of any or all other
            series of Preferred Stock.

            (f) Subject to the provisions of section (e), shares of any series
            of Preferred Stock may be issued from time to time as the Board of
            Directors of the Corporation shall determine and on such terms and
            for such consideration as shall be fixed by the Board of Directors.

            (g) Shares of Common Stock may be issued from time to time as the
            Board of Directors of the Corporation shall determine and on such
            terms and for such consideration as shall be fixed by the Board of
            Directors.

            (h) The authorized amount of shares of Common Stock and of Preferred
            Stock may, without a class or series vote, be increased or decreased
            from time to time by the affirmative vote of the holders of a
            majority of the stock of the Corporation entitled to vote thereon.

            FIFTH: - (a) The business and affairs of the Corporation shall be
            conducted and managed by a Board of Directors. The number of
            directors constituting the entire Board shall be not less than five
            nor more than twenty-five as fixed from time to time by vote of a
            majority of the whole Board, provided, however, that the number of
            directors shall not be reduced so as to shorten the term of any
            director at the time in office, and provided further, that the
            number of directors constituting the whole Board shall be
            twenty-four until otherwise fixed by a majority of the whole Board.

            (b) The Board of Directors shall be divided into three classes, as
            nearly equal in number as the then total number of directors
            constituting the whole Board permits, with the term of office of one
            class expiring each year. At the annual meeting of stockholders in
            1982, directors of the first class shall be elected to hold office
            for a term expiring at the next succeeding annual meeting, directors
            of the second class shall be elected to hold office for a term
            expiring at the second succeeding annual meeting and directors of
            the third class shall be elected to hold office for a term expiring
            at the third succeeding annual meeting. Any vacancies in the Board
            of Directors for any reason, and any newly created directorships
            resulting from any increase in the directors, may be filled by the
            Board of Directors, acting by a majority of the directors then in
            office, although less than a quorum, and any directors so chosen
            shall hold office until the next annual election of directors. At
            such election, the stockholders shall elect a successor to such
            director to hold office until the next election of the class for
            which such director shall have been chosen and until his successor
            shall be elected and qualified. No decrease in the number of
            directors shall shorten the term of any incumbent director.

            (c) Notwithstanding any other provisions of this Charter or Act of
            Incorporation or the By-Laws of the Corporation (and notwithstanding
            the fact that some lesser percentage may be specified by law, this
            Charter or Act of Incorporation or the By-Laws of the Corporation),
            any director or the entire Board of Directors of the

                                        8
<PAGE>   12
            Corporation may be removed at any time without cause, but only by
            the affirmative vote of the holders of two-thirds or more of the
            outstanding shares of capital stock of the Corporation entitled to
            vote generally in the election of directors (considered for this
            purpose as one class) cast at a meeting of the stockholders called
            for that purpose.

            (d) Nominations for the election of directors may be made by the
            Board of Directors or by any stockholder entitled to vote for the
            election of directors. Such nominations shall be made by notice in
            writing, delivered or mailed by first class United States mail,
            postage prepaid, to the Secretary of the Corporation not less than
            14 days nor more than 50 days prior to any meeting of the
            stockholders called for the election of directors; provided,
            however, that if less than 21 days' notice of the meeting is given
            to stockholders, such written notice shall be delivered or mailed,
            as prescribed, to the Secretary of the Corporation not later than
            the close of the seventh day following the day on which notice of
            the meeting was mailed to stockholders. Notice of nominations which
            are proposed by the Board of Directors shall be given by the
            Chairman on behalf of the Board.

            (e) Each notice under subsection (d) shall set forth (i) the name,
            age, business address and, if known, residence address of each
            nominee proposed in such notice, (ii) the principal occupation or
            employment of such nominee and (iii) the number of shares of stock
            of the Corporation which are beneficially owned by each such
            nominee.

            (f) The Chairman of the meeting may, if the facts warrant, determine
            and declare to the meeting that a nomination was not made in
            accordance with the foregoing procedure, and if he should so
            determine, he shall so declare to the meeting and the defective
            nomination shall be disregarded.

            (g) No action required to be taken or which may be taken at any
            annual or special meeting of stockholders of the Corporation may be
            taken without a meeting, and the power of stockholders to consent in
            writing, without a meeting, to the taking of any action is
            specifically denied.

            SIXTH: - The Directors shall choose such officers, agent and
            servants as may be provided in the By-Laws as they may from time to
            time find necessary or proper.

            SEVENTH: - The Corporation hereby created is hereby given the same
            powers, rights and privileges as may be conferred upon corporations
            organized under the Act entitled "An Act Providing a General

            amended.

            make, alter or repeal any By-Law whether or not adopted by them,
            provided however, that any such additional By-Laws, alterations or
            repeal may be adopted only by the affirmative vote of the holders of
            two-thirds or more of the outstanding shares of capital stock of the
            Corporation entitled to vote generally in the election of directors
            (considered for this purpose as one class).
