Payment Intangibles;  (xii)          All Goods;  (xiii)         All Instruments;  (xiv)        All Intellectual Property;  (xv)         All Inventory;  (xvi)        All Investment Property;  (xvii)       All Letter-of-Credit Rights;  (xviii)      All Money;  (xix)         All Records;  (xx)          All Supporting Obligations;  (xxi)         All property of the Issuer held by the

description now or hereafter in the possession or custody of or in transit to
the Indenture Trustee for any purpose, including, without limitation,

which the Issuer may have any right or power (but only to the extent such
property relates to the Owner Compressors and other Collateral acquired from
time to time);  (xxii)        All insurance proceeds of the Owner
Compressors and the other Collateral and all proceeds of the voluntary or

above, all income, payments and Proceeds of each of the foregoing and all
accessions to, substitutions and replacements for, and rents, profits and
products of each of the foregoing.  All of the property described
in this Granting Clause is herein collectively called the Collateral.  For avoidance of doubt it is expressly
understood and agreed that, to the extent the UCC is revised subsequent to the
date hereof such that the definition of any of the foregoing terms included in
the description of Collateral is changed, the parties hereto desire that any
property which is included in such changed definitions which would not
otherwise be included in the foregoing grant on the date hereof be included in
such grant immediately upon the effective date of such revision, it being the
intention of the  2


Issuer that
the description of Collateral set forth above be construed to include the
broadest range of assets. 
Notwithstanding the immediately preceding sentence, the foregoing grant
is intended to apply immediately on the date hereof to all Collateral to
fullest extent permitted by Applicable Law regardless of whether any particular
item of Collateral is currently subject to the UCC.  The Issuer hereby irrevocably
authorizes the Indenture Trustee and each Series Enhancer at any time, and from
time to time, to file, without the signature of the Issuer, in any filing
office in any jurisdiction necessary or desirable to perfect the security
interests and Liens granted herein or in any other Related Documents any
financing statements (including any such financing statement claiming a
security interest in all assets of the Issuer), continuation statements and
amendments thereto that (i) indicate or describe the Collateral regardless of
whether any particular asset comprised in the Collateral falls within the scope
of Article 9 of the UCC, in the same manner as described herein or in any other
manner as the Indenture Trustee or any Series Enhancer may determine in its
sole discretion is necessary or desirable to ensure the perfection of the
security interests and Liens granted herein, or (ii) provide any other
information required by Article 9 of the UCC for the sufficiency or filing
office acceptance of any financing statement or amendment, including whether
the Issuer is an organization, the type of organization and any organizational
identification number issued to the Issuer. 
The Issuer agrees to furnish any such information to the Indenture
Trustee or any Series Enhancer promptly upon the request from the Indenture
Trustee or such Series Enhancer.  The
Issuer also ratifies its authorization for the Indenture Trustee or any Series
Enhancer to have filed in any jurisdiction any like initial financing
statements or amendments thereto if filed prior to the date hereof.  Nothing in the foregoing shall be deemed to
create an obligation of the Indenture Trustee to file any financing statements,
continuation statements or amendments thereto.  ARTICLE I

certificate or other document, and accounting terms partly defined in this

under GAAP or regulatory accounting principles, the definitions contained in
this Indenture or in any such certificate or other document shall control.  3

Period, the related Record Date, the related Determination Date, and the related
Payment Date, shall mean, respectively, the Record Date occurring on the last
Business Day of such Collection Period and the Determination Date and Payment
Date next following the end of such Collection Period.  (e)      With respect to any
Series of Notes, the related Supplement shall mean the Supplement pursuant to
which such Series of Notes is issued and the related Series Enhancer shall
mean the Series Enhancer for such Series of Notes.  (f)       All references to the

applied, with respect to the Manager.  Section 103.           Computation of Time Periods.  Unless otherwise stated in this Indenture or
any Supplement issued pursuant to the terms hereof, in the computation of a
period of time from a specified date to a later specified date, the word from
means from and including and the words to and until each means to but
excluding.  Section 104.           Power of Attorney.    The Issuer hereby appoints the Indenture
Trustee as its designee for purposes of exercising any power of attorney or
right granted by the Manager pursuant to the Management Agreement.  ARTICLE II
THE NOTES  Section 201.           Authorization of Notes.  (a)  The number of Series or
Classes of Notes which may be created by this Indenture is not limited; provided, however, that, the issuance of
any Series of Notes shall (i) comply with the provisions of Section 1006 hereof
and (ii) not result in, or with the giving of notice or the passage of time or
both would result in, the occurrence of a Trigger Event.  The aggregate principal amount of Notes of
each Series which may be issued, authenticated and delivered under this
Indenture is not limited except as shall be set forth in any Supplement and as
restricted by the provisions of this Indenture.  (b)      The Notes issuable under
this Indenture shall be issued in such Series, and such Class or Classes within
a Series, as may from time to time be created by Supplement pursuant to this
Indenture.  Each Series shall be created
by a different Supplement and shall be designated, upon the face thereof, to
differentiate the Notes of such Series from the Notes of any other Series.  All of the Notes of a Series shall be
identical except to the extent set forth in the related Supplement.  The Issuer intends that each such Note shall
constitute a security within the meaning of Article 8 of the UCC.  (c)      Upon satisfaction of and
compliance with the requirements and conditions to closing set forth in the
related Supplement, Notes of the Series to be executed and delivered on a
particular Series Issuance Date pursuant to such related Supplement, may be
executed by the Issuer and  4


delivered
to the Indenture Trustee for authentication following the execution and
delivery of the related Supplement creating such Series or from time to time
thereafter, and the Indenture Trustee shall authenticate and deliver Notes upon
an Issuer request set forth in an Officers Certificate of the Issuer signed by
one of its Authorized Signatories, without further action on the part of the
Issuer.  Section 202.           Form of Notes; Global Notes.  (a)      Notes of any Series or
Class may be issued, authenticated and delivered, at the option of the Issuer,
as Public Global Notes, Rule 144A Global Notes, or Definitive Notes or as may
otherwise be set forth in a Supplement, and the form of such Notes shall be
substantially in the form attached as an exhibit to the related
Supplement.  Notes of each Series shall
be dated the date of their authentication and shall bear interest at such rate,
be payable as to principal, premium, if any, and interest on such date or dates,
and shall contain such other terms and provisions as shall be established in
the related Supplement.  Except as
otherwise provided in any Supplement, the Notes shall be issued in minimum
denominations of $1,000,000 and in integral multiples of $1,000,000 in excess
thereof; provided that one Note of each Class may be issued in a nonstandard
denomination.  (b)      If the Issuer shall
choose to issue Public Global Notes or Rule 144A Global Notes, such notes shall
be issued in the form of one or more Public Global Notes or one or more Rule
144A Global Notes which (i) shall represent, and shall be denominated in
an aggregate amount equal to, the aggregate principal amount of all Notes to be
issued hereunder, (ii) shall be delivered as one or more Notes held by the
Book Entry Custodian, or, if appointed to hold such Notes as provided below,
the Notes shall be registered in the name of the Depositary or its nominee,
(iii) shall be substantially in the form of the exhibits attached to the
related Supplement, with such changes therein as may be necessary to reflect
that each such Note is a Global Note, and (iv) shall each bear a legend
substantially to the effect included in the form of the exhibits attached to
the related Supplement.  (c)      Notwithstanding any other
provisions of this Section 202 or of Section 205, unless and until a
Global Note is exchanged in whole for Definitive Notes, a Global Note may be
transferred, in whole, but not in part, and in the manner provided in this
Section 202, only by (i) the Depositary to a nominee of such Depositary,
or (ii) by a nominee of such Depositary to such Depositary or another nominee
of such Depositary or (iii) by such Depositary or any such nominee to a
successor Depositary selected or approved by the Issuer or to a nominee of such
successor Depositary or in the manner specified in Section 202(d).  The Depositary shall order the Note Registrar
to authenticate and deliver any Book Entry Notes and any Global Note for each
Class of Notes having an aggregate initial outstanding principal balance equal
to the initial outstanding balance of such Class.  Note Owners shall hold their respective
Ownership Interests in and to such Notes through the book-entry facilities of
the Depositary.  Without limiting the
foregoing, any Note Owners shall hold their respective Ownership Interests, if
any, in Public Global Notes only through Depositary Participants.  (d)      If (i) the Issuer elects
to issue Definitive Notes, (ii) the Depositary for the Notes represented by one
or more Global Notes at any time notifies the Issuer that it is unwilling or
unable to continue as Depositary of the Notes or if at any time the Depositary
shall no longer be a clearing agency registered under the Exchange Act and any
other applicable statute or regulation, and a successor Depositary is not
appointed or approved by the Issuer within 90 days after the Issuer receives
such notice or becomes aware of such condition, as the case may be, (iii) the
Indenture Trustee, at the direction of the Control Party for a Series of Notes,
elects to terminate the book-entry system through the Depositary with respect
to such Series, or (iv) after an Event of Default or a Manager Default,
Noteholders representing more than fifty percent (50%) of a Series notify the
Depositary, or Book Entry Custodian, as the case may be, in writing that the
continuation of a book-entry system through the Depositary, or the Book Entry
Custodian, as the case may be, is no longer in the best interest of the  5


Noteholders
of such Series, the Issuer will promptly execute, and the Indenture Trustee,
upon receipt of an Officers Certificate evidencing such determination by the
Issuer, will promptly authenticate and make available for delivery, Definitive
Notes without coupons, in authorized denominations and in an aggregate
principal amount equal to the principal amount of the Global Note then
outstanding in exchange for such Global Note or as an original issuance of
Notes and this Section 202(d) shall no longer be applicable to the Notes.  Upon the exchange of the Global Notes for
such Definitive Notes without coupons, in authorized denominations, such Global
Notes shall be canceled by the Indenture Trustee.  All Definitive Notes shall be issued without
coupons.  Such Definitive Notes in
definitive form issued in exchange of the Global Notes pursuant to this
Section 202(d) shall be registered in such names and in such authorized
denominations as the Depositary in the case of an exchange or the Note
Registrar in the case of an original issuance, pursuant to instructions from
its direct or indirect participants or otherwise, shall instruct the Indenture
Trustee.  The Indenture Trustee may
conclusively rely on any such instructions furnished by the Depositary or the
Note Registrar, as the case may be, and shall not be liable for any delay in
delivery of such instructions.  The
Indenture Trustee shall make such Notes available for delivery to the Persons
in whose names such Notes are so registered.  (e)      As long as the Notes outstanding are represented by one or more
Global Notes:  (i)            the Note Registrar
and the Indenture Trustee may deal with the Depositary for all purposes
(including the payment of principal of and interest on the Notes) as the
authorized representative of the Note Owners;  (ii)           the rights of Note
Owners shall be exercised only through the Depositary and shall be limited to
those established by law and agreements between such Note Owners and the
Depositary and/or the Depositary Participants. 
Unless and until Definitive Notes are issued, the Depositary will make
book-entry transfers among the Depositary Participants and receive and transmit
payments of principal of, and interest on, the Notes to such Depositary
Participants; and  (iii)          whenever this
Indenture requires or permits actions to be taken based upon instructions or
directions of Holders of Notes evidencing a specified percentage of the voting
rights of a particular Series, the Depositary shall be deemed to represent such
percentage only to the extent that it has received instructions to such effect
from Note Owners and/or Depositary Participants owning or representing,
respectively, such required percentage of the beneficial interest in such
Series of Notes (or Class of Notes) and has delivered such instruction to the
Indenture Trustee.  (f)       Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Notes have been issued in definitive form to Note Owners, the
Indenture Trustee shall give all such notices and communications to the Depositary,
with a copy to each Series Enhancer.  (g)      The Indenture Trustee is
hereby initially appointed as the Book Entry Custodian and hereby agrees to act
as such in accordance with the agreement that it has with the Depositary
authorizing it to act as such.  The Book
Entry Custodian may, and, if it is no longer qualified to act as such, the Book
Entry Custodian shall, appoint, by written instrument delivered to the Issuer
and the Depositary, any other transfer agent (including the Depositary or any
successor Depositary) to act as Book Entry Custodian under such conditions as
the predecessor Book Entry Custodian and the Depositary or any successor
Depositary may prescribe, provided
that the predecessor Book Entry Custodian shall not be relieved of any of its
duties or responsibilities by reason of any such appointment of other than the
Depositary.  If the Indenture Trustee
resigns or is removed in accordance  6


with
the terms hereof, the successor Indenture Trustee or, if it so elects, the
Depositary shall immediately succeed to its predecessors duties as Book Entry
Custodian.  The Issuer and the Series
Enhancer for any Series shall have the right to inspect, and to obtain copies
of, any Notes held as Book-Entry Notes by the Book Entry Custodian.  (h)      No transfer of any Class
of Note or interest therein shall be made unless that transfer is made pursuant
to an effective registration statement under the Securities Act, and effective
registration or qualification under applicable state securities laws, or is
made in a transaction that does not require such registration or
qualification.  If a transfer of any
Definitive Note is to be made without registration under the Securities Act
(other than in connection with the initial issuance thereof or a transfer
thereof by the Depositary or one of its Affiliates), then the Note Registrar
shall refuse to register such transfer unless it receives (and upon receipt,
may conclusively rely upon) either:  (i)
a certificate from such Noteholder substantially in the form attached as
Exhibit A hereto or such other certification reasonably acceptable to the
Indenture Trustee and a certificate from such Noteholders prospective
transferee substantially in the form attached as Exhibit A hereto or such other
certification reasonably acceptable to the Indenture Trustee; or (ii) an
Opinion of Counsel satisfactory to the Indenture Trustee (which Opinion of
Counsel shall not be an expense of the Issuer or any Affiliate thereof) to the
effect that such transfer may be made without registration under the Securities
Act, together with the written certification(s) as to the facts surrounding
such transfer from the Noteholder desiring to effect such transfer and/or such
Noteholders prospective transferee on which such Opinion of Counsel is
based.  If such a transfer of any
interest in a Book-Entry Note is to be made without registration under the
Securities Act, the transferor will be deemed to have made each of the
representations and warranties set forth on Exhibit A hereto in respect of such
interest as if it was evidenced by a Definitive Note and the transferee will be
deemed to have made each of the representations and warranties set forth in
either Exhibit A hereto in respect of such interest as if it was evidenced by a
Definitive Note.  None of the Depositary,
the Issuer, the Indenture Trustee or the Note Registrar is obligated to
register or qualify any Class of Notes under the Securities Act or any other
securities law or to take any action not otherwise required under this
Indenture to permit the transfer of any Note or interest therein without
registration or qualification.  Any
Noteholder or Note Owner desiring to effect such a transfer shall, and does
hereby agree to, indemnify the Depositary, the Issuer, the Indenture Trustee,
each Series Enhancer and the Note Registrar against any liability that may
result if the transfer is not so exempt or is not made in accordance with such
federal and state laws.  Section 203.           Execution; Non-Recourse Obligation.  The Notes shall be executed on behalf of the
Issuer by manual or facsimile signature of an Authorized Signatory of the
Issuer.  The Notes shall be dated the
date of their authentication by the Indenture Trustee.  In case any Authorized Signatory
of the Issuer whose signature or facsimile signature shall appear on the Notes
shall cease to be an Authorized Signatory of the Issuer before the
authentication by the Indenture Trustee or the delivery of such Notes, such
signature or facsimile signature shall nevertheless be valid, sufficient and
binding for all purposes.  All Notes and the interest
thereon shall be limited recourse obligations of the Issuer and shall be
secured by all of the Issuers right, title and interest in the
Collateral.  The Notes shall never
constitute obligations of the Indenture Trustee, the Contributor, the Manager,
the Seller, any Series Enhancer or of any shareholder or any Affiliate of any
such Person (other than the Issuer) or any officers, directors, employees or
agents of any thereof, and no recourse may be had under or upon any obligation,
covenant or agreement of this Indenture, any Supplement or of any Notes, or for
any claim based thereon or otherwise in respect thereof, against any
incorporator or against any past, present, or future owner, partner of an owner
or any officer, employee or director thereof or of any successor entity, or any
other Person, either directly or through the Issuer, whether by virtue of any
constitution, statute or rule of law,  7


or by the
enforcement of any assessment or penalty or otherwise; it being expressly
agreed that this Indenture and the obligations issued hereunder and under any
Supplements hereto are solely obligations of the Issuer, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, any
other Person under or by reason of this Indenture, any Supplement or any Notes
or implied therefrom, or for any claim based thereon or in respect thereof, all
such liability and any and all such claims being hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Notes. 
Except as may be provided in any Supplement, no Person other than the
Issuer shall be liable for any obligation of the Issuer under this Indenture or
any Note or any losses incurred by any Noteholder.  Section 204.           Certificate of Authentication.  No Notes shall be secured hereby or entitled
to the benefit hereof or shall be or become valid or obligatory for any purpose
unless there shall be endorsed thereon by manual signature a certificate of
authentication by the Indenture Trustee, substantially in the form set forth in
the form of Note attached to the related Supplement.  Such certificate on any Note issued by the
Issuer shall be conclusive evidence and the only competent evidence that it has
been duly authenticated and delivered hereunder.  At the written direction of the
Issuer, the Indenture Trustee shall authenticate and deliver the Notes.  The Notes shall be dated the date of
authentication and delivery thereto by the Indenture Trustee.  It shall not be necessary that the same Authorized
Signatory of the Indenture Trustee execute the certificate of authentication on
each of the Notes.  Section 205.           Registration; Registration of
Transfer and Exchange of Notes.  (a)      The Indenture Trustee
shall keep at its Corporate Trust Office books in written form for the
registration and transfer or exchange of the Notes (the Note Register).  The Issuer hereby appoints the Indenture
Trustee as its registrar (the Note Registrar) and transfer agent to keep such
books and make such registrations and transfers or exchanges as are hereinafter
set forth in this Section 205 and also authorizes and directs the Indenture
Trustee to provide, upon written request by the Deal Agent or any Series
Enhancer, a copy of such registration record to the Deal Agent or such Series
Enhancer, as the case may be.  The names
and addresses of the Holders of all Notes and all transfers of, and the names
and addresses of the transferee of, all Notes will be registered in such Note
Register.  The Person in whose name any
Note is registered shall be deemed and treated as the owner and Holder thereof
for all purposes of this Indenture, and the Indenture Trustee, any related
Series Enhancer and the Issuer shall not be affected by any notice or knowledge
to the contrary.  If a Person other than
the Indenture Trustee is appointed by the Issuer to maintain the Note Register,
the Issuer will give the Indenture Trustee, the Deal Agent and any Series
Enhancer prompt written notice of such appointment and of the location, and any
change in the location, of the successor note registrar, and the Indenture
Trustee, the Deal Agent and any related Series Enhancer shall have the right to
inspect the Note Register at all reasonable times and to obtain copies thereof,
and the Indenture Trustee shall have the right to conclusively rely upon a
certificate executed on behalf of such successor note registrar by an officer
thereof as to the names and addresses of the Noteholders and Series, Class and
the principal amounts and number of such Notes.  (b)      Payments of principal,
premium, if any, and interest on any Note shall be payable on each Payment Date
only to the registered Holder thereof on the Record Date immediately preceding
such Payment Date.  The principal of,
premium, if any, and interest on each Note shall be payable at the Corporate
Trust Office of the Indenture Trustee in immediately available funds in such
coin or currency of the United States of America as at the time for payment
shall be legal tender for the payment of public and private debts.  Notwithstanding the foregoing or any
provision in any Note to the contrary, if so requested by the registered Holder
of any Note by written notice to the Indenture  8


Trustee,
all amounts payable to such registered Holder may be paid either (i) by
crediting the amount to be distributed to such registered Holder to an account
maintained by such registered Holder with the Indenture Trustee or by
transferring such amount by wire to such other bank in the United States,
including a Federal Reserve Bank, as shall have been specified in such notice,
for credit to the account of such registered Holder maintained at such bank, or
(ii) by mailing a check to such address as such Holder shall have
specified in such notice, in either case (subject to the provisions of
Section 207 hereof) without any presentment or surrender of such Note to
the Indenture Trustee at the Corporate Trust Office of the Indenture Trustee.  (c)      Upon surrender for
registration of transfer of any Note at the Corporate Trust Office and subject
to the conditions of this Section 205 the Issuer shall execute and the
Indenture Trustee or its agent, upon written request, shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Notes of the same Class, of any authorized denominations and of a like
aggregate original principal amount.  (d)      All Notes issued upon any
registration of transfer or exchange of Notes shall be the legal, valid and
binding obligations of the Issuer, evidencing the same debt, and entitled to
the same benefits under this Indenture and any Supplement, as the Notes
surrendered upon such registration of transfer or exchange.  (e)      Every Note presented or
surrendered for registration of transfer or for exchange shall (if so required
by the Issuer or the Indenture Trustee) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Issuer and the
Indenture Trustee duly executed, by the Holder thereof or his attorney duly
authorized in writing.  (f)       Any service charge, fees
or expenses made or expense incurred by the Indenture Trustee for any such
registration, discharge from registration or exchange referred to in this
Section 205 shall be paid by the Noteholder. 
The Indenture Trustee or the Issuer may require payment by the Holder of
a sum sufficient to cover any tax expense or other governmental charge payable
in connection therewith.  (g)      If Notes are issued or
exchanged in definitive form under Section 202, such Notes will not be
registered by the Indenture Trustee unless each Prospective Owner provides the
Manager, the Issuer, the Indenture Trustee and any Replacement Manager with a
written representation that the statements in either subsections (1) or (2) of
Section 208 is an accurate representation as to all sources of funds to be used
to pay the purchase price of the Notes.  (h)      No transfer of a Note
shall be deemed effective unless (x) the transferee of such Note has
certified (or shall have been deemed to have certified) that it is not a
Competitor and (y) the registration and prospectus delivery requirements
of Section 5 of the Securities Act and any applicable state securities or Blue
Sky laws are complied with, or such transfer is exempt from the registration
and prospectus delivery requirements under the Securities Act and such
laws.  In the event that a transfer is to
be made without registration or qualification, such Noteholders prospective
transferee shall deliver to the Indenture Trustee an investment letter
substantially in the form of Exhibit A hereto (the Investment Letter).  The Indenture Trustee is not under any
obligation to register the Notes under the Securities Act or any other
securities law or to bear any expense with respect to such registration by any
other Person or monitor compliance of any transfer with the securities laws of
the United States, regulations promulgated in connection thereto or ERISA
unless the Notes are issued or exchanged in definitive form under Section 202.  9


(i)       Notwithstanding the
foregoing, the restrictions set forth in clauses (g) and (h) of Section 205
hereof shall not be applicable to any transfer of any Note (or an interest
therein) by (i) any Noteholder to any liquidity provider as provided in the
Supplement for a Series of Warehouse Notes, (ii) any Noteholder to any Series
Enhancer with respect to such Series of Notes, or (iii) at any time any
Reimbursement Amounts are owing to a Series Enhancer, any Series Enhancer to
any subsequent Noteholder.  Section 206.           Mutilated, Destroyed, Lost and
Stolen Notes.  (a)  If
(i) any mutilated Note is surrendered to the Indenture Trustee or the Note
Registrar, or the Indenture Trustee receives evidence to its satisfaction of
the destruction, loss or theft of any Note, and (ii) there is delivered to
the Indenture Trustee, the Issuer or each Series Enhancer with respect to such
Note, such security or indemnity as the Indenture Trustee, the Issuer and such
Series Enhancer may require to hold the Indenture Trustee, the Issuer and such Series
Enhancer (and any agent of any of them) harmless (the unsecured indemnity of a
Rated Institutional Noteholder being deemed satisfactory for such purpose),
then the Issuer shall execute and the Indenture Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Note, a replacement Note of the same Series and Class and maturity and
of like terms as the mutilated, destroyed, lost or stolen Note; provided, however, that if any such
destroyed, lost or stolen Note, but not a mutilated Note, shall have become, or
within thirty (30) days shall be or become due and payable, the Issuer may pay
such destroyed, lost or stolen Note when so due or payable instead of issuing a
replacement Note.  (b)      If, after the delivery of
such replacement Note, or payment of a destroyed, lost or stolen Note pursuant
to the proviso to the preceding sentence, a bona fide purchaser of the original
Note in lieu of which such replacement Note was issued presents for payment
such original Note, the Issuer, the related Series Enhancer for such Series and
the Indenture Trustee shall be entitled to recover upon the security or
indemnity provided therefor to the extent of any and all loss, damage, cost or
expense incurred by the Issuer or the Indenture Trustee in connection
therewith.  (c)      The Indenture Trustee and
the Issuer may, for each new Note authenticated and delivered under the
provisions of this Section 206, require the advance payment by the Noteholder
of the expenses, including counsel fees, service charges and any tax or
governmental charge which may be incurred by the Indenture Trustee or the
Issuer.  Any Note issued under the
provisions of this Section 206 in lieu of any Note alleged to be destroyed,
mutilated, lost or stolen, shall be equally and proportionately entitled to the
benefits of this Indenture with all other Notes of the same Series and
Class.  The provisions of this Section
206 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 Notes.  Section 207.           Delivery, Retention and
Cancellation of Notes.  Each
Noteholder is required, and hereby agrees, to surrender to the Indenture
Trustee, prior to the Legal Final Maturity Date for such Series, any Note on
which the final payment due thereon has been made.  Any such Note as to which the Indenture
Trustee has made or holds the final payment thereon shall be deemed canceled
and, unless any unreimbursed payment on such Note has been made by a Series
Enhancer for such Series, shall no longer be Outstanding for any purpose of
this Indenture, whether or not such Note is ever returned to the Indenture
Trustee.  Matured Notes delivered upon
final payment to the Indenture Trustee and any Notes transferred or exchanged
for other Notes shall be canceled and disposed of by the Indenture Trustee in
accordance with its policy of disposal and the Indenture Trustee shall promptly
deliver to the Issuer such canceled Notes upon reasonable prior written
request.  If the Indenture Trustee shall
acquire, for its own account, any of the Notes, such acquisition shall not
operate as a redemption or satisfaction of the indebtedness represented by such
Notes.  If the Issuer shall acquire any
of the Notes, such acquisition shall operate as a redemption or satisfaction of
the indebtedness represented by such Notes. 
Notes which  10


have been canceled by the Indenture Trustee
in accordance with the terms of this Indenture shall be deemed paid and
discharged for all purposes under this Indenture.  Section 208.           ERISA Deemed Representations.  Each prospective initial Noteholder acquiring
Notes, each prospective transferee acquiring the Notes, and each prospective
owner (or transferee thereof) of a beneficial interest in Notes (each, a Prospective
Owner) will be deemed to have represented by such purchase to the Issuer, the
Indenture Trustee, the Manager and any Replacement Manager that either (i) it
is not acquiring the Notes with the assets of a Plan or (ii) the acquisition
and holding of the Notes will not give rise to a nonexempt prohibited
transaction under Section 406(a) of ERISA or Section 4975 of the Code.  Section 209.           Determination of Requisite Global
Majority.  A requisite global
majority (a Requisite Global Majority) shall exist with respect to any action
proposed to be taken pursuant to the terms of the Indenture or any Supplement
if: (a) the Control Party or Control Parties, as the case may be,
representing in aggregate more than fifty percent (50%) of the then Aggregate
Note Principal Balance shall approve or direct such proposed action (in making
such a determination the following rules shall be employed: (i) for purposes of
measuring the Aggregate Note Principal Balance, a Series of Warehouse Notes for
which the Commitment Termination Date has not occurred shall be deemed to have
an unpaid principal balance equal to the aggregate Existing Commitment of such
Series, and (ii) each Control Party of a Series shall be deemed to have voted
the entire unpaid principal balance of all Notes of the related Series in favor
of, or in opposition to, such proposed action, as the case may be); and
(b) unless Control Parties representing in aggregate more than sixty-six
and two thirds percent (66 2/3%) of the Aggregate Note Principal Balance shall
have approved or directed such proposed action, each Series Enhancer with
respect to each Series of Notes, regardless of whether a Series Enhancer Default
with respect to such Series Enhancer shall have occurred and be continuing as
of any date of determination, shall have also approved or directed such
proposed action.  Except as otherwise provided in
Section 1002, the Indenture Trustee, provided it has sent out notices in
accordance with this Indenture, shall act as directed by the Requisite Global
Majority.  In addition, the Indenture
Trustee shall not have any liability for failing to act if not directed by the
Requisite Global Majority in a reasonably timely manner.  By acceptance of a Note, each Noteholder and
Note Owner agree to the foregoing provisions.  ARTICLE III
PAYMENT OF NOTES; ESTABLISHMENT OF ACCOUNTS; CONTROL REQUIREMENTS; STATEMENTS
TO NOTEHOLDERS  Section 301.           Principal and Interest.  Distributions of principal, premium, if any,
and interest on any Series or Class of Notes shall be made to Noteholders of
each Series and Class as set forth in Section 302 of this Indenture and the
related Supplement.  The Overdue Rate for
the Note of any Series shall be as set forth in the related Supplement.  If interest or principal amounts are paid by
a Series Enhancer, then the Default Fee shall be owed to such Series Enhancer
and shall not be paid to applicable Noteholders of such Series. If a Series
Enhancer shall have failed to pay interest or principal amounts when due in
accordance with the terms of any applicable Enhancement Agreement, then any
such Default Fee shall be payable to the Noteholders of such Series.  Section 302.           Trust Account.  (a)  On or prior to the Closing
Date, the Indenture Trustee shall establish and maintain the Trust Account with
Wells Fargo Bank, National Association until all Outstanding Obligations and
all amounts owing by the Issuer pursuant to the terms of each Enhancement Agreement
and each Interest Rate Swap Agreement have been paid in full.  The Trust  11


Account shall be in the name of the Indenture
Trustee, on behalf of the Noteholders, each Letter of Credit Bank, each Interest
Rate Hedge Provider and each Series Enhancer, pursuant to the terms of this
Indenture. Neither the Issuer nor the Indenture Trustee shall establish any
additional Trust Accounts or other bank or investment accounts without the
prior written consent of each Letter of Credit Bank and each Series Enhancer.  The Issuer shall promptly notify each
Interest Rate Hedge Provider of any new or additional Trust Account established
subsequent to the Closing Date.  (b)      The Issuer shall cause
all Securitization Collections (whether received directly by the Issuer or on
deposit from time to time in the Lockbox Account or the ABS Lockbox Account) to
be deposited into the Trust Account or, to the extent provided herein, the
Purchase Account.  (c)      The Issuer hereby directs
and authorizes the Indenture Trustee, upon the Indenture Trustees receipt of
any written request to such effect from the Manager pursuant to the terms of
Section 7.3 of the Management Agreement and subject to the provisions of this
Section 302(c), to distribute to the Manager from the Trust Account on a
Business Day other than a Payment Date funds in an amount equal to the sum of
(i) an estimate (based on actual accrued amounts as of the date of such
request) of the Operations Fee and S&A Fee expected to be paid on the
immediately succeeding Payment Date, and (ii) so long as the Overhaul Fee
Release Conditions are satisfied on the date of such request, an estimate of
the Overhaul Fee (based on actual accrued amounts) expected to be paid on the
immediately succeeding Payment Date; provided, however,
that notwithstanding any right of the Manager pursuant hereto or pursuant to
the Management Agreement to request such interim distributions with respect to
the Operations Fee, S&A Fee and Overhaul Fee, such interim distributions
shall be made only so long as (i) no Event of Default or Manager Default shall
have occurred and be continuing, and (ii) unless the Indenture Trustee (as
directed by the Requisite Global Majority) shall have consented to such interim
distribution(s), the Manager Termination Date shall not have occurred.  In addition,
so long as no Event of Default shall have occurred and be continuing, the
Issuer hereby directs and authorizes the Indenture Trustee, upon the Indenture
Trustees receipt of a written request from Manager on any Business Day, to
distribute to the Manager from the Trust Account an amount equal to the sum of
(x) all Excluded Payments then on deposit in the Trust Account, and (y) so long
as all Scheduled Principal Payment Amounts with respect to all Series of Notes
then Outstanding were paid in full on the immediately preceding Payment Date,
all Ineligible Collections then on deposit in the Trust Account.  All interim
distributions pursuant to the provisions of this Section 302(c) shall be made
on the same day on which such request of the Manager is received, unless such
request is received after 10:00 a.m., New York City time, in which case such
amount shall be distributed on the immediately succeeding Business Day.  The Indenture Trustee is under no obligation
to verify that the conditions to any interim distributions set forth in this
Section 302(c) have been satisfied before making such distributions; provided, that the Indenture Trustee shall not make any such
interim distributions if it shall have received written notice from the Issuer
or any Series Enhancer that such applicable conditions are not satisfied and
the Indenture Trustee shall not have received any subsequent notice from such
Person terminating such earlier notice.  (d)      On each Payment Date on
which no Event of Default is then continuing, the Indenture Trustee (based on
the Manager Report delivered to it pursuant to the Management Agreement), shall
distribute the Available Distribution Amount (as reduced by any amounts
distributed during the related Collection Period pursuant to Section 302(c)
above) from the Trust Account by wire transfer in immediately available funds
to the following Persons in the following order of priority and in the
following amounts:  12


(1)      to the Indenture Trustee,
an amount equal to the sum of (i) all Indenture Trustees Fees and
(ii) Indenture Trustee Indemnified Amounts then due and payable for all
Series then Outstanding; provided, however,
that the amount set forth in clause (ii) shall not exceed $20,000 annually for
each Series then Outstanding;  (2)first, to the Manager, any Excluded Payments
received during the related Collection Period (to the extent not previously
paid to the Manager pursuant to the provisions of Section 302(c)) which amounts
shall, if applicable, be promptly remitted by the Manager to the relevant tax
authorities, and second, after all amounts owing pursuant to clause first have been paid, to the Manager,
reimbursement for any unpaid Manager Advances in accordance with the terms of
the Management Agreement;  (3)      to the Manager, an amount
equal to any S&A Fee and Operations Fee then due and payable (which amounts
shall have been reduced for any related amounts previously distributed to the
Manager pursuant to Section 302(c) hereof);  (4)first, to the Back-up Manager, an amount equal to
any Back-up Manager Fee then due and owing and not previously paid by the
Manager; and second, after the
payments pursuant to clause first have been
paid, to the Manager, an amount
equal to any Back-up Manager Fee previously paid by the Manager and not
previously reimbursed;  (5)      if the Manager is not a
Universal Affiliate, then first,
to each applicable insurance provider or such other Person to whom such amounts
are payable, on a pro rata basis
based on the relative amounts then owing, an amount equal to any premiums then
due in respect of Property Insurance and Liability Insurance (to the extent not
paid by any Universal Affiliate), and second,
to the Control Party for each Series, on a pro
rata basis based on the relative amounts then owing, an amount equal
to any unreimbursed premiums previously paid by such Control Party in respect
of Property Insurance and Liability Insurance (to the extent not paid by any
Universal Affiliate);  (6)      to each Letter of Credit
Bank, on a pro rata basis based
on the relative amount of Letter of Credit Fees then owing to each Letter of
Credit Bank, an amount equal to the Letter of Credit Fees then due and payable
to such Letter of Credit Bank;  (7)      to each Series Enhancer,
on a pro rata basis based on the
relative amounts of Premium owing to each Series Enhancer, an amount equal to
all Premiums then due and payable to such Series Enhancer;  (8)      to each Interest Rate
Hedge Provider (on apro
rata basis based on the
relative amounts owing to all such Interest Rate Hedge Providers), an amount
equal to any scheduled payments (other than termination payments), and any
accrued interest thereon, then due and payable pursuant to the terms of all
Interest Rate Swap Agreements then in effect to which such Interest Rate Hedge
Provider is a counterparty with the Issuer;  13


(9)      to the Series Account for
each Series of Notes then Outstanding, an amount equal to the Interest Payments
for each such Series then due and payable (provided that any portion of the
Interest Payments relating to the reimbursement of Interest Payments previously
paid by a Series Enhancer (together with interest thereon at the rate specified
in the applicable Enhancement Agreement) shall be paid directly to the related
Series Enhancer).  If sufficient funds do
not exist on such Payment Date to pay in full all amounts then due and owing
pursuant to this clause (9), the remaining Available Distribution Amount shall
be allocated among all Series of Notes then Outstanding in the same proportion
as the ratio of (x) the Interest Payments then due and owing with respect to a
particular Series of Notes, to (y) the aggregate amount of all Interest
Payments then due and owing to all Series of Notes pursuant to this clause (9);  (10)    in payment of the amounts
described in clauses (A) and (B) below:  (A)          to
the Series Account for each Series of Warehouse Notes then Outstanding, on a pro rata basis, an amount equal to the sum of the Commitment

Trustee to the Reserve Account shall be invested in Eligible Investments in
accordance with this Indenture and shall be distributed in accordance with this
Section 313 and Section 314(d).  (b)      On each Payment Date, the
Indenture Trustee shall, in accordance with the Manager Report, withdraw from
the Reserve Account and deposit into the Trust Account funds in an amount equal
to the excess, if any, of (A) an amount equal to the sum of (i) amounts
then on deposit in the Reserve Account (calculated after giving effect to all
deposits to, and withdrawals from, the Reserve Account on such Payment Date)
and (ii) the aggregate Available Drawing Amount under all Eligible Letters
of Credit in effect on such Payment Date (in each case calculated after giving
effect to all Letter of Credit Drawings to be made on such Payment Date) or if
established, the amount on deposit in the Letter of Credit Collateral Account,
over (B) the Required Reserve Amount for such Payment Date.  (c)      In the event that the
Manager Report with respect to any Determination Date shall state that
(i) funds on deposit in the Trust Account will not be sufficient  (after giving effect to the payment of all
amounts payable higher in priority under Section 302(d) or 302(e), as
applicable) to make payment in full of the maintenance payments, Overhaul Fees,
Operations Fees, or S&A Fees then due and payable(the amount of any such deficiency, collectively, a Maintenance
Payment Deficiency), and/or (ii) the funds on deposit in any Series
Account will not be sufficient (after giving effect to the payment of all
amounts payable higher in priority under Section 302(d) or 302(e), as
applicable) to make payment in full on the related Payment Date of the related
Interest Payment then due for such Series (the amount of any such deficiency,
an Interest Payment Deficiency), then the Indenture Trustee shall draw on the
Reserve Account, in accordance with the Manager Report,  in an amount equal to the lesser of (x) the
Permitted Payment Date Withdrawal and (y) the amount of funds then on
deposit in the Reserve Account.  In
either case, the Indenture Trustee shall transfer funds from the Reserve
Account to the Manager, in the case of a Maintenance Payment Deficiency, or the
related Series Account in the case of an Interest Payment Deficiency, in
accordance with the Manager Report.  As
used herein, Permitted Payment Date Withdrawal means the sum of (i) the
Maintenance Payment Deficiency and (ii) the Interest Payment Deficiency.  24


(d)If the amount on deposit in the Reserve Account on a Determination Date
is not sufficient to pay in full the aggregate Permitted Payment Date
Withdrawals referred to in Section 313(c) above, then a drawing will be made on
the Letter of Credit (or if established, the Letter of Credit Collateral
Account(s)) in accordance with the provisions of Section 314 hereof.  (e)On the Legal Final Maturity Date for the Series with the latest Legal
Final Maturity Date, any remaining funds in the Reserve Account shall be
deposited in the Trust Account and distributed in accordance with Section 302
of this Indenture and the related Supplements.  Section 314.Letters
of Credit.  (a)The Issuer shall provide to the Indenture Trustee on or before the
Closing Date and maintain so long as any Outstanding Obligations remain unpaid,
one or more Eligible Letters of Credit, for the benefit of the Indenture
Trustee, on behalf of the Noteholders and the other Entitled Parties, in an
aggregate available amount on any date of not less than the Required Reserve
Amount.  (b)If the amounts withdrawn from the Reserve Account on a Payment Date in
accordance with the provisions of Section 313(c) hereof are not sufficient to
pay in full all Permitted Payment Date Withdrawals for such Payment Date (the
amount of such deficiency, the Letter of Credit Permitted Draw), then the
Indenture Trustee shall, in accordance with the Manager Report, submit to the
Letter of Credit Bank (or, if established, make a draw from amounts on deposit
in the Letter of Credit Collateral Account) a completed Drawing Certificate (as
defined in the Letter of Credit) requesting a drawing, in accordance with, and
under the Letter of Credit (a Letter of Credit Drawing) in an amount equal to
the lesser of (x) the Letter of Credit Permitted Draw and (y) the
Available Drawing Amount.  If more than
one Eligible Letter of Credit is in effect on such date, then such Letter of
Credit Drawing will be allocated among such Eligible Letters of Credit (or, if
applicable, the Letter of Credit Collateral Account), on a pro rata
basis, based on the relative Available Drawing Amounts on each such Eligible
Letter of Credit (or, in the case of a Letter of Credit Collateral Account,
based on amounts then on deposit therein).  (c)The Indenture Trustee shall receive the proceeds of all Letter of
Credit Drawings as attorney-in-fact for each of the Entitled Parties (and shall
deposit such proceeds into the Trust Account) and any such Letter of Credit
Drawings shall be used only to pay any Letter of Credit Permitted Drawings.  The making of any Letter of Credit Drawing
does not relieve the Issuer of any obligation under the Indenture or any other
Related Documents.  (d)If at any time the Letter of Credit Bank shall not be an Eligible Bank,
and the Issuer or the new Letter of Credit Bank shall fail to deliver a
replacement Eligible Letter of Credit within three (3) Business Days after the
Requisite Global Majority delivered written notice to the Indenture Trustee
that such condition initially occurred, the Indenture Trustee shall, unless the
Requisite Global Majority otherwise directs the Indenture Trustee in writing,
submit to the Letter of Credit Bank a completed Drawing Certificate in amount
equal to the remaining Available Drawing Amount under such Letter of
Credit.  Any amount received by the
Indenture Trustee as a result of any such drawing under this Section 314(d)
shall be deposited into a separate Eligible Account with the Corporate Trust
Office of the Indenture Trustee which shall be designated as a letter of credit
collateral account (a Letter of Credit Collateral Account) and disbursed in
accordance with the provisions of this Section 314 hereof.  Upon receipt by the Indenture Trustee of a
replacement Eligible Letter of Credit in accordance with the provisions of this
Section 314(d), the Indenture Trustee shall withdraw from the Letter of Credit
Collateral Account and remit to the Letter of Credit Bank for the replaced
Letter of Credit, funds in an amount equal to the lesser of (i) the Available
Drawing Amount on the  25


replacement
Eligible Letter of Credit and (ii) the amounts then on deposit in the Letter
of Credit Collateral Account.  Section 315.Purchase
Account.  (a)On or prior to the Closing Date, the Indenture Trustee shall establish
and maintain in the name of the Indenture Trustee an Eligible Account with the
Corporate Trust Office of the Indenture Trustee which shall be designated the
purchase account (the Purchase Account) and which shall be held by the
Indenture Trustee pursuant to this Indenture. 
Any and all moneys remitted by the Issuer, or the Manager on the Issuers
behalf, to the Purchase Account, together with any Eligible Investments in
which such moneys are or will be invested or reinvested, shall be held in the
Purchase Account.  Any and all moneys in
the Purchase Account shall be invested in Eligible Investments in accordance
with this Indenture and shall be distributed in accordance with this Section
315.  (b)The Issuer shall (or shall cause the Manager to) deposit into the
Purchase Account all Compressor Reinvestment Sales Proceeds.  The Issuer may, so long as no Series Enhancer
has sent written direction to the contrary to each of the Issuer, the Manager,
the Indenture Trustee and each other Series Enhancer, use, or cause the use of,
all or any portion of the Compressor Reinvestment Sales Proceeds then on
deposit in the Purchase Account to pay to the Contributor the purchase price
for one or more Compressors that satisfy the Additional Compressor Criteria and
the Purchase Criteria pursuant to a transaction complying with the terms of the
Contribution Agreement and this Indenture, by delivering a written notice and
certificate to the Indenture Trustee (1) specifying (x) the amount of
Compressor Reinvestment Sales Proceeds to be released from the Purchase Account
and paid over to the Contributor, (y) the applicable Purchase Date on
which such amount shall be released and paid and (z) a description of the
Additional Compressors to be purchased and (2) representing and warranting to
the Indenture Trustee, each Noteholder, each Series Enhancer, each Letter of
Credit Bank and each Interest Rate Hedge Provider that, as at the Purchase Date
for such Additional Compressors, such Additional Compressors satisfy all of the
Additional Compressor Criteria and the Purchase Criteria.  (c)If the Issuer does not utilize all of the Compressor Reinvestment Sales
Proceeds to purchase Additional Compressors within thirty (30) days after the
date on which such Compressor Reinvestment Sales Proceeds were initially
deposited into the Purchase Account, then the Indenture Trustee, at the
direction of the Manager or any Series Enhancer, shall transfer from the
Purchase Account to the Trust Account any unused portion of such Compressor
Reinvestment Sales Proceeds. In determining whether or not all of the
Compressor Reinvestment Sales Proceeds arising from a specific Owner Compressor
were re-invested in Additional Compressors within a thirty (30) day period, the
Issuer shall utilize a first-in, first out method of tracking Compressor
Reinvestment Sales Proceeds.  (d)Upon the occurrence of either a Trigger Event or a Prospective Trigger
Event, the Indenture Trustee, at the direction of the Manager or any Series
Enhancer, as the case may be, shall promptly liquidate all Eligible Investments
credited to the Purchase Account and transfer all funds from the Purchase
Account to the Trust Account.  ARTICLE IV

Trustee for the benefit of the Noteholders, each Series Enhancer, each Letter
of Credit Bank and each Interest Rate Hedge Provider, and (y) payments in
respect of such User Contracts, Accounts, Contracts and Instruments shall be
made directly to the ABS Lockbox Account, and the Indenture Trustee and/or the
Requisite Global Majority (and/or any such designee) may communicate with such
Users and other Account Debtors, parties to such Contracts and obligors in
respect of such Instruments to verify with such parties, to the Indenture
Trustees and Requisite Global Majoritys satisfaction, the existence, amount
and terms of such User Contracts, Accounts, Contracts and Instruments.  The Indenture Trustee hereby agrees that it
will cause amounts on deposit from time to time in the ABS Lockbox Account, if
any, to be deposited into the Trust Account.  Section 402.Pro
Rata Interest.  (a) All Series
of Notes Outstanding shall be equally and ratably entitled to the benefits of
this Indenture without preference, priority or distinction, all in accordance
with the terms and provisions of this Indenture and the related Supplement.  (b)With respect to each Series of Notes, the execution and delivery of the
related Supplement shall be upon the express condition that, if the conditions

Indenture with respect to such Series of Notes shall cease and become null and
void and all of the property, rights, and interest granted as security for the

direction of, the Requisite Global Majority, shall perform or comply, or
otherwise cause performance or compliance, with such agreement.  The  29


reasonable
expenses, including attorneys fees and expenses, of the Indenture Trustee
incurred in connection with such performance or compliance, together with
interest thereon at the Overdue Rate specified in the related Supplement, shall
be payable by the Issuer to the Indenture Trustee on demand and shall
constitute additional Outstanding Obligations secured hereby.  (f)Each of the Issuer, the Indenture Trustee, each Series Enhancer and, by
its acceptance of its respective Note, each Noteholder, hereby agrees that, if
the Indenture Trustee shall fail to act as directed by the Requisite Global
Majority at any time at which it is so required to act hereunder or under any
other Related Document, or if the Indenture Trustee shall fail to deliver a
completed Drawing Certificate to the Letter of Credit Bank as and when required
under Section 314 hereof, then, in each case, the Requisite Global Majority
shall be entitled to take such action directly in its own capacity or on behalf

when so required to act under any Related Document, then the Indenture Trustee
shall, upon the request of the Requisite Global Majority, irrevocably appoint
the Person designated by the Requisite Global Majority, and any officer or
agent thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of the Indenture Trustee and in the name of the Indenture Trustee or in
its own name, to take any and all actions that the Indenture Trustee is
authorized to take under any Related Document, to the extent the Indenture
Trustee has failed to take such action when and as required under such Related
Document.  Section 404.Release

a Manager Termination Notice terminating the Manager of its responsibilities in
accordance with the terms of the Management Agreement.  Upon receipt of such Manager Termination
Notice, the Back-up Manager shall, subject to the limitations set forth in the

evidencing such inability as set forth in the Back-up Management Agreement) and
if the Back-up Manager is unable to locate and qualify a replacement Manager
within sixty (60) days after the date of delivery of the Manager Termination

the Indenture Trustee or  30


Deal Agent may, with the written consent of
the Requisite Global Majority, make such arrangements for the compensation of
such Replacement Manager out of the Trust Account as the Indenture Trustee
acting at the direction of the Requisite Global Majority and such Replacement
Manager shall agree.  The Indenture
Trustee shall take such action, consistent with the Management Agreement and
the other Related Documents, as shall be necessary to effectuate the
appointment and installation of the Back-up Manager or another Replacement
Manager.  (b)Upon a Corporate Trust Officers obtaining the receipt of written
notice by the Indenture Trustee that a Warranty Purchase Amount has not been
paid when due pursuant to the terms of the Related Documents, the Indenture
Trustee shall notify each Control Party and each Series Enhancer of such event
and shall, in the name of the Issuer, in the Indenture Trustees own name or
otherwise (as directed by the Requisite Global Majority) enforce any applicable
repurchase obligations of the Seller, the Contributor or any other Person at
the direction of the Requisite Global Majority.  (c)The Indenture Trustee shall as promptly as practicable (and in any

contemplated under the Related Documents, including, inter alia, any issuance or sale of the Notes pursuant to

Regulations.  The Issuer does not own
any margin security, as that term is defined in Regulation U of the Federal
Reserve Board, and the proceeds of the Notes issued under this Indenture will
be used only for the purposes contemplated hereunder. None of the proceeds of
the Notes will be used, directly or indirectly, for the purpose of purchasing
or carrying any margin security, for the purpose of reducing or retiring any
indebtedness which was originally incurred to purchase or carry any margin
security or for any other purpose which might cause any of the loans under this
Indenture to be considered a purpose credit within the meaning of Regulations
T, U and X. Issuer will not take or permit any agent acting on its behalf to
take any action which might cause this Indenture or any document or instrument

impositions shown thereon to be due and payable by Issuer have been paid prior
to the date on which any fine, penalty, interest or late charge may be added
thereto for nonpayment thereof, or any such fine, penalty, interest, late
charge or loss has been paid, or Issuer is contesting its liability therefor in
good faith and has fully reserved all such amounts according to GAAP in the
financial statements provided to the Noteholders pursuant to Section 626 of
this Indenture.  Issuer has paid when due
and payable all material charges upon the books of Issuer and no Governmental
Authority has asserted any Lien against Issuer with respect to unpaid Taxes.  Proper and accurate amounts have been
withheld by Issuer from its employees for all periods in full and complete
compliance with the tax, social security and unemployment withholding
provisions of applicable federal, state, local and foreign law and such
withholdings have been timely paid to the respective Governmental Authorities.  Section 512.Other

and the application of the proceeds and repayment thereof by Issuer, the
granting of the security interest and Liens hereunder and the performance of

with the terms of this Indenture or any other Related Document to which it is a

respect to transactions contemplated by this Indenture and the other Related
Documents to which it is a party; and  (iii)is not in violation in any respect of any term of any agreement,

respects.  Section 522.Security
Interest Representations.  (a) This
Indenture creates a valid and continuing security interest (as defined in the
UCC) and Lien in the Collateral in favor of the Indenture Trustee for the
benefit of the Noteholders, each Series Enhancer and each Interest Rate Hedge
Provider, which security interest, upon the execution and delivery of the
Control Agreements and the completion of the filings referred to in Section
522(d) being duly made, is a perfected first priority security interest prior
to all other Liens, and is enforceable as such as against creditors of and
purchasers from the Issuer.  (b)The Compressors constitute equipment or inventory within the
meaning of the UCC.  The User Contracts
constitute tangible chattel paper or accounts within the meaning of the UCC
and the rights thereunder constitute general intangibles within the meaning
of the UCC.  Each of the Transaction

of similar import to be duly filed in the proper filing office in the
appropriate jurisdictions under Applicable Law in order to perfect the security
interest in the Collateral granted to the Indenture Trustee in this Indenture

interest in favor of the Indenture Trustee.

statement to the following effect: A purchase of, or security interest in or a
Lien on, any collateral described in this financing statement will violate the
rights of the Indenture Trustee.  (e)Other than the security interest granted to the Indenture Trustee
pursuant to this Indenture or granted in any of the Related Documents, the
Issuer has not pledged, assigned, sold, granted a security interest in or a
Lien (except for Permitted Encumbrances) on or otherwise conveyed any of the
Collateral, except as permitted pursuant hereto or in the Related
Documents.  The User Contracts that
constitute or evidence the Collateral do not have any marks or notations
indicating that they have been pledged, assigned or otherwise conveyed to any
Person other than the Indenture Trustee. 
The Issuer has not authorized the filing of, and is not aware of, any
financing statements against the Issuer that include a description of
collateral covering any Collateral other than any financing statement or
document of similar import (i) relating to the security interest granted to the
Indenture Trustee in this Indenture, or (ii) that has been terminated.  The Issuer is not aware of any judgment or
tax lien filings against the Issuer.  (f)The Issuer has received all necessary consents and approvals required
by the terms of the Collateral to pledge to the Indenture Trustee of its interest
and rights in such Collateral hereunder.  (g)The Issuer has taken all steps necessary to cause the Securities

records the Indenture Trustee as the Person having a security entitlement in

the Indenture Trustee or the Securities Intermediary.  Neither the Issuer nor the Indenture Trustee
has  consented to compliance of the
Securities Intermediary with entitlement orders of any Person other than the
Indenture Trustee.  The representations and
warranties set forth in this Section 522 shall survive until this Indenture is
terminated in accordance with its terms. 
Breaches of the representations and warranties set forth in this Section
522 may not be waived by the Indenture Trustee (acting at the direction of the
Requisite Global Majority and the Interest Rate Hedge Providers), unless the
Rating Agency Condition shall have been satisfied prior to such waiver.  Section 523.Ordinary
Course.  The transactions
contemplated by this Indenture and the other Related Documents are being
consummated by the Issuer in furtherance of the Issuers ordinary business
purposes and constitute a practical and reasonable course of action by the
Issuer designed to improve the financial position of the Issuer, with no
contemplation of insolvency and with no intent to hinder, delay or defraud any
of its present or future creditors.  37

Requisite Global Majority, with appropriate changes thereof and additions
thereto as from time to time may be required by law in order to protect Issuers

Outstanding Obligations, the representations and warranties contained herein
shall have a continuing effect as having been true when made.  Section 526.Intellectual
Property.  The Issuer has no
Intellectual Property.  ARTICLE VI

Requirements.  (a) The Issuer
will enter into within thirty (30) days after the Closing Date and within thirty
(30) days after the issuance of any additional Series entered into after the
Closing Date (or such shorter time period as set forth in the related Series Supplement)
and at all times that any Outstanding Obligations remain unpaid maintain one or
more Interest Rate Swap Agreements with one or more Interest Rate Hedge
Providers having an aggregate notional balance at any time of (x) not less
than the product of (i) ninety percent (90%) and (ii) an amount equal
to the sum of (1) the then unpaid principal balance of all Series of Term
Notes then Outstanding that bear interest based on a variable rate of interest,
and (2) the excess of (A) the then unpaid principal balance of all
Series of Warehouse Notes then Outstanding that bear interest based on a
variable rate of interest, over (B) Twenty Million Dollars ($20,000,000)
(the amount described in this clause (x), the Minimum Hedging Amount), and
(y) not more than the product of (i) one hundred five percent (105%) and (ii)
the then Aggregate Note Principal Balance (the product set forth in this clause
(y), the Maximum Hedging  45


Amount). 
Each Interest Rate Hedge Provider shall be an Eligible Interest Rate
Hedge Counterparty on the date on which the related Interest Rate Swap
Agreement is originated.  The
amortization of the Interest Rate Swap Agreement(s) will be consistent with the
expected current and future principal balances of the above-referenced Notes
without taking into consideration additional acquisitions of Owner
Compressors.  All of the foregoing
requirements shall be collectively referred to as the Hedging Requirements.  Each Series Enhancer shall have the right to
review and approve prior to the execution thereof by the Issuer, each Interest
Rate Swap Agreement (or amendments to any existing Interest Rate Swap
Agreement) entered into subsequent to the Closing Date that differs in any
material respect from the Interest Rate Swap Agreements in effect on the
Closing Date.  (b)If the Issuer is required to enter into additional transactions and/or
terminate transactions under existing Interest Rate Swap Agreements in order to
comply with the Hedging Requirements, then
the Issuer shall provide notice of such condition to the Indenture Trustee,
each Interest Rate Hedge Provider and each Series Enhancer within five (5)
Business Days after such condition is determined to exist. The Issuer (or the
Manager on behalf of the Issuer) shall remedy such imbalance by the next
succeeding Payment Date.  If the Hedging
Requirements are not satisfied, and if the Issuer has failed to remedy same
within such period, then the Indenture Trustee (at the written direction of the
Requisite Global Majority) shall have the right to (i) with respect to a
failure to comply with the Minimum Hedging Amount, enter into (and shall enter
into as and when the Requisite Global Majority Party shall direct in writing)
Interest Rate Swap Agreements on behalf of the Issuer to remedy such condition,
and (ii) with respect to a failure to comply with the Maximum Hedging Amount,
terminate, on behalf of the Issuer, one or more Interest Rate Swap Agreements
in order to remedy such condition.  The
calculations to be made under this Section 631 shall exclude all transactions
where the Issuer is not required to make any scheduled periodic payments other
than premium payments or fees.  So long
as a Trigger Event is continuing, neither the Issuer nor the Manager on its
behalf shall enter into any additional transactions under Interest Rate Swap
Agreements, except with the approval of each Series Enhancer and each Interest
Rate Hedge Provider.  So long as no Trigger
Event is then continuing, the Issuer may exercise its commercially reasonable
discretion in selecting the specific transactions and notional amounts thereof
to be terminated or reduced.  If a
Trigger Event is then continuing, then (i) if there is only one
institution serving as the Interest Rate Hedge Provider with respect to all
Interest Rate Swap Agreements then in effect, such Interest Rate Hedge Provider
shall select the specific Interest Rate Swap Agreements to be terminated and
(ii) at all times not covered by clause (i), the notional reductions shall
be effected over all outstanding transactions under Interest Rate Swap
Agreements then in effect on a pro rata
basis, based on the respective notional amounts for each calculation period, so
that the notional amounts for each current and future calculation period will
comply with the Hedging Requirements.  If
the Issuer fails to terminate or reduce transactions as required in this
Section 631, the Indenture Trustee (acting at the written direction of the
Requisite Global Majority) shall reduce the notional amounts, in whole or in
part, for all outstanding transactions under each Interest Rate Swap Agreement
then in effect on a pro rata
basis, based on the respective notional amounts for each calculation period in
accordance with the Hedging Requirements. 
The Indenture Trustee shall have no duty to monitor such events, and
shall be required to take action in respect of the provisions of this Section
631 only upon written direction of the Person(s) entitled to give such
direction.  (c)[Intentionally Omitted]  (d)[Intentionally Omitted]  (e)On each Determination Date, Issuer shall provide or cause to be
provided to the Indenture Trustee, each Interest Rate Hedge Provider and each
Series Enhancer, a monthly report reflecting the hedging policy calculations as
of the end of the preceding calendar month based on all  46


transactions
outstanding as of the end of such month under Interest Rate Swap Agreements
then in effect, including transactions which are scheduled to commence on a
future date.  (f)The termination provisions provided for in this Indenture relating to
the Interest Rate Swap Agreements are in addition to, and not to the exclusion
of, any termination provisions contained in the Interest Rate Swap Agreements.  (g)All payments received from an Interest Rate Hedge Provider shall be
deposited by the Issuer directly into the Trust Account in accordance with
Section 302 hereof.  Section 632.Separate
Identity.  The Issuer makes herein by
this reference each of the representations and warranties made by it to Gardere
Wynne Sewell LLP in support of its opinions respecting the consolidation of the
Issuer and certain other parties issued and delivered in connection with the
issuance of the Notes, as if specifically made herein and agrees to comply with
each of the factual assumptions contained in such opinions.  Section 633.Annual
Perfection Opinion.  Within 90 days

Issuer shall furnish to the Indenture Trustee, the Deal Agent, each Interest
Rate Hedge Provider, each Rating Agency and each Series Enhancer, an Opinion of
Counsel either stating that, in the opinion of such counsel, such action has
been taken with respect to the recording, filing, re-recording and refiling of

with respect to the execution and filing of any financing statements and
continuation statements, as are necessary to maintain the Lien created by this
Indenture and reciting the details of such action or stating that, in the
opinion of such counsel, no such action is necessary to maintain such Lien.  Section 634.Identification
Marks.  The Issuer shall use its best
efforts to cause, within ninety (90) days after the Closing Date, the
applicable Contribution Date or the applicable Substitution Date, as the case
may be, and at all times thereafter, each Owner Compressor acquired by the
Issuer on the Closing Date or any Contribution Date or Substitution Date, to
prominently display a sticker with the applicable phrase described in Section
525 hereof, or other appropriate words designated by the Indenture Trustee,
with appropriate changes thereof and additions thereto as from time to time may
be required by law in order to protect Issuers and the Indenture Trustees
interests in such Owner Compressors.  The
Issuer shall not allow the name of any Person to be placed upon any Owner
Compressor as a designation that might be interpreted as indicating a claim of
ownership thereto or a security interest therein by any Person other than
Issuer or the Indenture Trustee.  Section 635.Storage
of Contract Files.  The Issuer shall
at all times cause the Manager to maintain at its Houston, Texas office, all

pollution laws (including notifications and

used and operated solely in the manner for which it was intended and in
accordance with the license or certificate, if any, provided by the
manufacturer thereof.  The Issuer shall
use reasonable precautions to prevent loss or damage to each Owner Compressor
from fire and other hazards.  The Issuer
shall not permit any Owner Compressor to be used in any unlawful trade or in
any manner that would violate any law that would expose such Owner Compressor
to penalty, forfeiture or capture.  Section 637.Maintenance
and Repair of Owner Compressors.  The
Issuer, at its sole cost and expense, shall maintain (or cause the Manager to
maintain):  (i)each Owner Compressor in a manner consistent

provisions of this Section 638, the Issuer shall not modify or alter any
Owner Compressor without the prior written approval of the Indenture Trustee (acting
at the direction of the Requisite Global Majority).  (ii)In case any Owner Compressor (or any part or component thereof) is
required to be altered, added to, replaced or modified in order to comply with
any insurance policies required pursuant to this Indenture or Applicable Law
(any such alteration, additional replacement or modification, a Required
Alteration), the Issuer agrees to promptly make (or cause to be made) such
Required Alteration at its own expense. Thereupon, such Required Alteration
shall immediately become subject to the terms and conditions of this Indenture.  (iii)The Issuer may make any optional renovation, improvement, addition, or
alteration to any Owner Compressor (any such renovation, improvement, addition
or alteration, an Optional Alteration) provided that such Optional Alteration
does not  48


impair
the value, use or remaining useful life of such Owner Compressor. To the extent
any Optional Alteration is not readily removable without impairing the value,
use or remaining useful life of the Owner Compressor to which such Optional
Alteration has been made, or is a part or appliance which replaces any part or
appliance originally incorporated or installed in or attached to such Owner
Compressor on the Effective Date for the related Supplement, such Optional
Alteration shall be subject to the terms of this Indenture and the Supplement
to which the related Owner Compressor is subject.  Section 639.User

satisfaction and discharge of this Indenture and the security and Liens hereby
created, and to release the Issuer from its covenants contained in this
Indenture and the Supplements hereto in connection with the satisfaction and
discharge of the Indenture.  The
Indenture Trustee shall be entitled to receive an Opinion of Counsel stating
that such satisfaction and discharge is authorized and permitted.  Section 702.Prepayment
of Notes.  (a)Optional Prepayments.  The Issuer may, from time to time, make an
optional Prepayment of principal of the Notes of any Series at the times, in
the amounts and subject to the conditions and limitations set forth in the
Supplement for the Series of Notes to be prepaid.  Any optional Prepayment of principal made by
the Issuer pursuant to this Section 702 shall also include accrued interest to
the date of the prepayment on the amount being prepaid.  All Prepayments made in accordance with this
Section 702(a) shall be accomplished by a deposit of funds (including any
amounts required pursuant to the provisions of Section 702(c) hereof) directly into
the Trust Account.  Notice of any
voluntary prepayment of a Series of Term Notes to be made by the Issuer
pursuant to the provisions of this Section 702(a) shall be given by the Issuer
to the Indenture Trustee and, if applicable, any Series Enhancer for such
Series of Notes to be prepaid, not later than the tenth (10th) day
prior to the date of such prepayment and not earlier than the Payment Date
immediately preceding the date of such prepayment.  (b)Mandatory Prepayments.  If at any time the Supplemental Principal
Payment Amount for any Payment Date is more than zero, then the Issuer shall,
in accordance with Section 302 on such Payment Date make a payment of the
Supplemental Principal Payment Amount which Supplemental Principal Payment
Amount shall be paid in the following order of priority:  (i)to each Series of Warehouse Notes then
Outstanding for which the Commitment Termination Date has not occurred on pro rata basis, in
proportion to the  52


then
unpaid principal balance of such Series of Warehouse Notes to the unpaid
principal balances of all such Series of Warehouse Notes, until the principal
balances of all such Series of Warehouse Notes have been paid in full;  (ii)if any Supplemental Principal Amount remains after application of
clause (i), then the aggregate amount of such excess shall be applied to each
Series of Warehouse Notes then Outstanding for which the Commitment Termination
Date has occurred on a pro ratabasis,
in proportion to the then unpaid principal balance of such Series of Warehouse
Notes to the unpaid principal balances of all such Series of Warehouse Notes
then Outstanding, until the principal balances of all of such Series of Warehouse
Notes have been paid in full; and  (iii)if any Supplemental Principal Amount remains after application of
clause (ii), then the aggregate amount of such excess shall be applied to each
Series of Term Notes then Outstanding on a pro ratabasis,
in proportion to the then unpaid principal balance of such Series of Term Notes
to the unpaid principal balances of all Series of Term Notes then Outstanding.  Solely for purposes of determining the
Supplemental Principal Payment Amount for purposes of this Section 702(b), a
determination of whether or not a Trigger Event is continuing on any Payment
Date shall be determined in accordance with the following criteria:  (i)each of a Manager Default and an Event of
Default shall continue until such event or condition has been waived by
(i) in the case of any payment default (including an Event of Default
under clause (i) or (ii) of Section 801 hereof), 100% of the Control
Parties and, to the extent required pursuant to Section 808 or 1002(a), each
affected Noteholder, and (ii) in any other case, the Requisite Global
Majority and any other Person or Persons required to consent to such waiver
pursuant to Section 813;  (ii)a Net Revenue Event shall continue until the next succeeding
Determination Date on which the related Manager Report indicates that such condition
no longer exists, at which time such event shall be deemed to have been cured;
and  (iii)an Undercollateralization Event shall continue until the next
succeeding Determination Date on which the related Manager Report indicates
that such condition no longer exists, at which time such event shall be deemed
to have been cured;  provided, however,the
events described in clauses (i), (ii) and (iii) may not, solely for purposes of
determining whether a Supplemental Principal Payment Amount is payable, be
waived or cured on more than two (2) occasions.  (c)Repayment of Interest Rate Hedge Provider.  If
the Issuer has elected to make a voluntary Prepayment in accordance with the
provisions of Section 702(a) above or is required to make a Prepayment in accordance
with the provisions of Section 702(b) above, then in addition to such
Prepayment, the Issuer shall pay such amount, including any termination
payments, necessary (in each case as determined by the Requisite Global
Majority and after taking account of payment priorities set forth in Section
302 hereunder) to reduce the aggregate notional balance of all outstanding
transactions under the Interest Rate Swap Agreements in accordance with the
terms of Section 631 hereof and the terms of the related Interest Rate Swap
Agreements.  So long as no Trigger Event
or Event of Default is then continuing, the Issuer (or the Manager on its
behalf) may exercise its discretion in selecting the specific transactions and
the notional amounts thereof to be terminated. 
If a Trigger Event or Event of  53


Default is then continuing the outstanding transactions under the
Interest Rate Swap Agreements will be terminated on a pro rata basis, based on the respective
notional amounts for each remaining calculation period so that the remaining
notional amounts for all future calculation periods under such transactions
shall comply with the requirements of Section 631(a) and not exceed such
requirements by more than the amounts set forth in Section 631(b)(ii) hereof.  (d)Adjustment of Prospective Minimum Principal Payment Amounts and
Scheduled Principal Payment Amounts for Partial Voluntary Prepayments.  In
the event that the Issuer makes a voluntary prepayment of less than all of the
then unpaid principal balance of any Series of Term Notes in accordance with
the provisions of Section 702(a), then the Issuer shall promptly (but in any
event within ten (10) Business Days after the date on which such prepayment is
made) thereafter recalculate the Minimum Targeted Principal Balances and
Scheduled Targeted Principal Balances for such Series of Notes for each future
Payment Date such that, after giving effect to such adjustment, each subsequent
Minimum Targeted Principal Balance and Scheduled Targeted Principal Balance for
such Series of Term Notes shall be reduced by an amount equal to the quotient
of (i) the aggregate amount of such prepayment actually received by the
Noteholders of such Series, divided by (ii) the number of remaining Payment
Dates to and including, the Legal Final Maturity Date (in the case of
adjustments to future Minimum Principal Payment Amounts) or Expected Final
Payment Date (in the case of adjustments to future Scheduled Principal Payment
Amounts).  (e)Allocation
of Targeted Adjustment Amount.  If
the Manager Report delivered on any Determination Date indicates that a
Targeted Adjustment Amount exists, then the Issuer shall promptly (but in any
event within ten (10) Business Days) after receipt of such Manager Report, apply
such Targeted Adjustment Amount in the following order of priority:  (i)to
reduce (but not below zero) by the amount of such Targeted Adjustment Amount each
of the Minimum Targeted Principal Balance and the Scheduled Targeted Principal
Balance, in each case, for all remaining Payment Dates of any Series of
Warehouse Notes for which the Commitment Termination Date has occurred (or, if
there are multiple Series of Warehouse Notes for which the Commitment
Termination Date has occurred, such Targeted Adjustment Amount shall be
allocated among each such Series of Warehouse Notes on a pro ratabasis
based on each such Seriess then respective unpaid principal balances, and  (ii)if
any Targeted Adjustment Amount remains after application of clause (i), with
respect to either the Minimum Targeted Principal Balance or the Scheduled
Targeted Principal Balance on the next succeeding Payment Date, then, in each
such case, the amount of such excess in the aggregate shall be allocated on a pro rata basis (based on then unpaid principal balances)
among all Series of Term Notes then Outstanding and the amount allocated to
each such Series shall then be used toreduce
(but not below zero) the Minimum Targeted Principal Balances and the Scheduled
Targeted Principal Balances, as applicable, in each case, for all remaining
Payment Dates of such Series of Term Notes by the amount of such allocated Targeted
Adjustment Amount.  ARTICLE VIII

Note; and, in addition thereto, such further amount as shall be sufficient to
cover all other Outstanding Obligations and the costs and out-of-pocket
expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Indenture Trustee, any Series Enhancer and their respective

however,that no Owner Compressor may be sold pursuant
to this Section 804 unless the purchase price therefor is in cash in an amount
not less than the Depreciated Value for such Owner Compressor, unless all of the
Control Parties consent to such sale; and provided, further,

Section 804 unless the aggregate Net Compressor Sales Proceeds to be realized
from such Sale equal or exceed the amount required to repay in full all of the

shall not be necessary to make any Noteholder a party to any such Proceedings.  (b)      All rights of action and
claims under this Indenture, the related Supplement or such Notes may be
prosecuted and enforced by the Indenture Trustee without the possession of any
of the Notes or the production thereof in any Proceeding relating thereto, and
any such Proceeding instituted by the Indenture Trustee shall be brought in its
own name as trustee of an express trust, and any recovery whether by judgment,
settlement or otherwise shall, after provision for the payment of the

made, by the Indenture Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Notes and each Interest Rate Hedge Provider,
subject to the subordination of payments among Classes of a particular Series
as set forth in the related Supplement.  Section 806.           Allocation of Money Collected.  If the Notes of all Series have been declared
due and payable following an Event of Default and such declaration and its
consequences have not been rescinded or annulled, any money collected by the

Trustee has, for thirty (30) days after its receipt by a Corporate Trust
Officer of such notice, request and offer of security or indemnity, failed to
institute any such Proceeding;  (v)           no direction
inconsistent with such written request has been given to the Indenture Trustee
during such thirty (30) day period by the Requisite Global Majority; and  (vi)          if such Series of
Notes has the benefit of an Enhancement Agreement, a Series Enhancer Default has
occurred and is continuing.  60

Supplement) or to enforce any right under this Indenture, except in the manner
herein provided and for the benefit of all Noteholders.  Section 808.           Right of Holders to Receive

right to receive payment of principal under its Notes prior to the Legal Final
Maturity Date therefor nor shall any such Noteholder institute any Proceeding
for the enforcement of any such payment prior to such Legal Final Maturity

Trustee, any Series Enhancer, any Interest Rate Hedge Provider or any Holder of
any Note to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. 
Every right and remedy given by this Article or by law to the Indenture
Trustee or to the Holders may be exercised from time to time, and as often as
may be deemed expedient, by the Indenture Trustee, any Series Enhancer, any
Interest Rate Hedge Provider, any Letter of Credit Bank, or the Holders, as the
case may be, subject to the right of the Control Party to control such right pursuant
to Section 812 hereof.  Section 812.           Control by Requisite Global
Majority.  Upon the occurrence of an
Event of Default, the Requisite Global Majority shall, except as set forth in
the proviso to Section 804 hereof, have the right to direct the time, method
and place of conducting any Proceeding for any remedy available to the
Indenture Trustee or exercising any trust or power conferred on the Indenture
Trustee, provided that
(i) such direction shall not be in conflict with any rule of law or with
this Indenture, including, without limitation, Section 804 hereof,
(ii) such Requisite Global Majority has offered to the Indenture Trustee
reasonable security or indemnity against costs, expenses and liabilities which
it might incur in connection therewith as provided in Section 902(iii) hereof
and (iii) the Indenture Trustee may take any other action deemed proper by
the Indenture Trustee which is not inconsistent with such direction.  61


Section 813.           Waiver of Past Defaults.  (a) The Requisite Global Majority may,
on behalf of all Noteholders of all Series, waive any past Event of Default and
its consequences, except that:  (i)            a waiver of any
payment default (including any Event of Default under clause (i) or (ii) of
Section 801 hereof) shall require the consent of all of the Control Parties and,
to the extent required pursuant to Section 1002(a), each affected Noteholder, and
shall not require Requisite Global Majority consent;  (ii)           any waiver in
respect of a covenant or provision hereof which, pursuant to Section 1002
hereof, cannot be modified or amended without the consent of (x) each
Holder of each Outstanding Note affected thereby and each Series Enhancer or
(y) each Control Party for each Series of Notes or (z) the Series
Enhancer under the Series 2005-1 Supplement, shall require the consent of such
Persons as are required to amend such covenant or provision (in addition to the
consent of the Requisite Global Majority); and  (iii)          any
waiver by the Requisite Global Majority with respect to any Event of Default
shall not be effective until the tenth (10th) Business Day following
delivery of notice thereof to the Series Enhancer for the Series 2005-1 Notes
unless such Series Enhancer otherwise agrees.  (b)      Upon any waiver pursuant
to Section 813(a) above, such Event of 
Default shall cease to exist and shall be deemed to have been cured and
not to have occurred for every purpose of this Indenture; provided, however, that no such waiver
shall extend to any subsequent or other Event of Default or impair any right
consequent thereon.  No such waiver shall
affect any Interest Rate Swap Agreement that has been terminated in accordance
with its terms.  Section 814.           Undertaking for Costs.  All parties to this Indenture agree, and each
Holder of any Note by acceptance thereof shall be deemed to have agreed, that
any court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Indenture Trustee
for any action taken, suffered or omitted by it as the Indenture Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys fees and expenses, against any party litigant
in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; provided,
however, that the provisions of this Section shall not apply to any
suit instituted by the Indenture Trustee, to any suit instituted by any Holder,
or group of Holders, holding in the aggregate more than 10% of the aggregate
principal balance of the Notes of all Series then Outstanding, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of
or interest on any Note on or after the Legal Final Maturity Date of such Note.  Section 815.           Waiver of Stay or Extension Laws.  The Issuer covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Indenture; and the Issuer
(to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Indenture Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.  Section 816.           Sale of Collateral.  (a) The power to effect any sale (a Sale)
of any portion of the Collateral pursuant to Section 804 hereof shall not be
exhausted by any one or more Sales as to any portion of the Collateral
remaining unsold, but shall continue unimpaired until the entire  62


Collateral shall have been sold or all
Outstanding Obligations shall have been paid in full.  The Indenture Trustee (at the direction of
the Requisite Global Majority) may from time to time postpone any Sale by
public announcement made at the time and place of such Sale.  (b)      Upon any Sale, whether
made under the power of sale hereby given or under judgment, order or decree in
any Proceeding for the foreclosure or involving the enforcement of this
Indenture:  (i) the Indenture
Trustee, at the written direction of the Requisite Global Majority, may bid for
and purchase the property being sold, and upon compliance with the terms of
such Sale may hold, retain and possess and dispose of such property in
accordance with the terms of this Indenture; and (ii) the receipt of the
Indenture Trustee or of any officer thereof making such Sale shall be a
sufficient discharge to the purchaser or purchasers at such Sale for its or
their purchase money, and such purchaser or purchasers, and its or their
assigns or personal representatives, shall not, after paying such purchase money
and receiving such receipt of the Indenture Trustee or of such officer
therefor, be obliged to see to the application of such purchase money or be in
any way answerable for any loss, misappropriation or non-application thereof.  (c)      The Indenture Trustee shall
execute and deliver an appropriate instrument of conveyance transferring its
interest in any portion of the Collateral in connection with a Sale
thereof.  In addition, the Indenture
Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the
Issuer to transfer and convey its interest (subject to users rights of quiet
enjoyment) in any portion of the Collateral in connection with a Sale thereof,
and to take all action necessary to effect such Sale.  No purchaser or transferee at such a Sale
shall be bound to ascertain the Indenture Trustees authority, inquire into the
satisfaction of any conditions precedent or see to the application of any
monies.  (d)      The Indenture Trustee
acknowledges that its right to sell, transfer or otherwise convey any Interest
Rate Swap Agreement or exercise any foreclosure rights with respect thereto
shall be subject to compliance with the provisions of the applicable Interest
Rate Swap Agreement.  Section 817.           .Action on Notes.  The Indenture Trustees right to seek and
recover judgment on the Notes or under this Indenture or any Supplement shall
not be affected by the seeking, obtaining or application of any other relief
under or with respect to this Indenture or any Supplement.  Neither the Lien of this Indenture nor any
rights or remedies of the Indenture Trustee, any Series Enhancer, any Interest
Rate Hedge Provider or the Noteholders shall be impaired by the recovery of any
judgment by the Indenture Trustee against the Issuer or by the levy of any
execution under such judgment upon any portion of the Collateral or upon any of
the assets of the Issuer.  Section 818.           Determination of Existence of
Event of Default for Purposes of Section 302(e).  The Indenture Trustee shall distribute
amounts pursuant to the provisions of Section 302(e) hereof on each Payment
Date that occurs during the period commencing on the Indenture Trustees
receipt of notice from the Manager, the Issuer, the Contributor or the
Requisite Global Majority that an Event of Default has occurred and is
continuing on the date of such notice and ending on the date on which the
applicable Event of Default has been waived in a written notice to the
Indenture Trustee and Issuer executed by the Persons required to consent
thereto pursuant to Section 813.  Section 819.           Waiver of Trigger Event.  Any waiver of a Trigger Event (other
than an Event of Default) shall not be effective until the fifth (5th)
Business Day following delivery of notice thereof to the Series Enhancer for
the Series 2005-1 Notes unless such Series Enhancer otherwise agrees.  Section 820.           Notification of Each Series
Enhancer.  Upon the Indenture Trustees
receipt of notice with respect to, without duplication, (1) any exercise
by the Requisite Global Majority of its rights under any Related Document,
(2) any direction or instruction by the Requisite Global Majority  63


with respect to any Related Document or
(3) any declaration, waiver or other action of the Requisite Global
Majority under any Related Document, the Indenture Trustee shall deliver a
written notice to each Series Enhancer (other than any Series Enhancer
constituting part of such Requisite Global Majority) informing it of such
exercise, direction, instruction, declaration, waiver or action no later than
one (1) Business Day after the Indenture Trustees receipt of the applicable
notice.  ARTICLE IX
CONCERNING THE INDENTURE TRUSTEE  Section 901.           Duties of the Indenture Trustee.  The Indenture Trustee, prior to the occurrence
of an Event of Default or after the cure or waiver of any Event of Default that
may have occurred, undertakes to perform such duties and only such duties as
are specifically set forth in this Indenture and the related Supplement and no
implied duties shall be inferred against it. 
If an Event of Default with respect to any Series has occurred and is
continuing, the Indenture Trustee, at the written direction of the Control
Party, shall exercise such of the rights and powers vested in it by this
Indenture and the related Supplement, and use the same degree of care and skill
in its exercise as a prudent Person would exercise or use under the
circumstances in the conduct of such Persons own affairs.  The Indenture Trustee, upon
receipt of all resolutions, certificates, statements, opinions, reports,
documents, orders or other instruments furnished to the Indenture Trustee which
are specifically required to be furnished pursuant to any provisions of this
Indenture and any applicable Supplement, shall determine whether they are
substantially in the form required by this Indenture and any applicable
Supplement; provided, however,
that the Indenture Trustee shall not be responsible for the accuracy or content
(including mathematical calculations) of any such resolution, certificate,
statement, opinion, report, document, order or other instrument furnished
pursuant to this Indenture and any applicable Supplement.  No provision
of this Indenture or any Supplement shall be construed to relieve the Indenture
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct; provided,
however, that:  (i)            Prior to the
occurrence of an Event of Default and after the cure or waiver of any Event of
Default that may have occurred, the duties and obligations of the Indenture
Trustee shall be determined solely by the express provisions of this Indenture
and any Supplements issued pursuant to the terms hereof.  The Indenture Trustee shall not be liable
except for the performance of such duties and obligations as are specifically
set forth in this Indenture and any Supplements issued pursuant to the terms
hereof, and no implied covenants or obligations shall be read into this
Indenture against the Indenture Trustee and, in the absence of bad faith on the
part of the Indenture Trustee, the Indenture Trustee may conclusively rely, as
to the truth of the statements and the correctness of the opinions expressed
therein, upon any certificates, statements, reports, documents, orders, opinions
or other instruments (whether in their original or facsimile form) furnished to
the Indenture Trustee and conforming to the requirements of this Indenture and
any Supplements issued pursuant to the terms hereof;  (ii)           The Indenture
Trustee shall not be liable for an error of judgment made in good faith by a
Corporate Trust Officer or Corporate Trust Officers of the Indenture Trustee,
unless it shall be proved that the Indenture Trustee was negligent in
ascertaining the pertinent facts; and  64


(iii)          The Indenture
Trustee shall not be personally liable with respect to any action taken,
suffered or omitted to be taken by it in good faith in accordance with the
direction of the Control Party relating to the time, method and place of
conducting any proceeding for any remedy available to the Indenture Trustee, or
exercising any trust or power conferred upon the Indenture Trustee, under this
Indenture.  No provisions of this Indenture
shall require the Indenture Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of its duties
hereunder, 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
security or indemnity against such risk or liability is not reasonably assured
to it (the unsecured indemnity of (A) a Rated Institutional Noteholder, or (B)
any Series Enhancer (so long as its claims paying ability is rated AAA by
S&P or Aaa by Moodys, as applicable) shall not constitute reasonable
grounds for believing that repayment of any such funds is not reasonably
assured to it.)  Whether or not therein
expressly so provided, every provision of this Indenture relating to the
conduct or affecting the liability of or affording protection to the Indenture
Trustee shall be subject to the provisions of this Section 901.  Section 902.           Certain Matters Affecting the
Indenture Trustee.  Except as
otherwise provided in Section 901 hereof:  (i)            The Indenture
Trustee may conclusively rely and shall be fully protected in acting or
refraining from acting upon any Opinion of Counsel, certificate of an officer
of the Manager, certificate of auditors or any other certificate, statement,
instrument, opinion, report, notice, request, consent, order, appraisal, bond
or other paper or document (whether in its original or facsimile form)
reasonably believed by it to be genuine and to have been signed or presented by
the proper party or parties;  (ii)           The Indenture
Trustee may consult with counsel of its selection and any advice of such
counsel shall be full and complete authorization and protection in respect of
any action taken or suffered or omitted by it hereunder in good faith and in
accordance in reliance thereof;  (iii)          The Indenture
Trustee shall be under no obligation to institute, conduct or defend any
litigation or proceeding hereunder or in relation hereto at the request, order
or direction of the Control Party, pursuant to the provisions of this Indenture,
unless the Control Party shall have offered to the Indenture Trustee reasonable
security or indemnity satisfactory to it against the costs, expenses and
liabilities which may be incurred therein or thereby (the unsecured indemnity
of (A) a Rated Institutional Noteholder being deemed satisfactory for such
purpose or (B) any Series Enhancer (so long as its claims paying ability is
rated AAA by S&P or Aaa by Moodys as applicable) being deemed
satisfactory for such purpose);  (iv)          The Indenture Trustee
shall not be liable for any action taken, suffered or omitted by it in good
faith and believed by it to be authorized or within the discretion or rights or
powers conferred upon it by this Indenture;  (v)           The Indenture
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, consent, order, approval, bond or other paper or document,
unless requested in writing to do so by the Control Party; provided, however that the Indenture  65


Trustee
may require reasonable security or indemnity satisfactory to it against any
cost, expense or liability likely to be incurred in making such investigation
as a condition to so proceeding (the unsecured indemnity of (A) a Rated
Institutional Noteholder being deemed satisfactory for such purposes or (B) any
Series Enhancer (so long as its claims paying ability is rated AAA by S&P
or Aaa, by Moodys as applicable) being deemed satisfactory for such
purpose).  The reasonable expense of any
such examination shall be paid, on a pro
rata basis, by the Noteholders or, if paid by the Indenture Trustee,
shall be reimbursed by such Noteholders upon demand;  (vi)          The Indenture
Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through its agents or attorneys and the
Indenture Trustee shall not be responsible for any misconduct or negligence on
the part of any agent or attorney appointed by it with due care hereunder; provided, however, that any agreement with
an agent or an attorney shall provide for due care by such agent or attorney in
respect of the Issuer;  (vii)         The Indenture
Trustee shall not be charged with knowledge of any default or Event of Default
unless either a Corporate Trust Officer of the Indenture Trustee shall have
actual knowledge or written notice of such shall have been actually received by
a Corporate Trust Officer of the Indenture Trustee; and  (viii)        the rights,
privileges, protections, immunities and benefits given to the Indenture
Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Indenture Trustee in each of its
capacities hereunder, and to each agent, custodian and other Person employed to
act hereunder.  The provisions of this Section
902 shall be applicable to the Indenture Trustee in its capacity as the
Indenture Trustee under this Indenture. 
Delivery of any reports, information and documents to the Indenture
Trustee provided for herein (or in any Related Document) is for informational
purposes only and the Indenture Trustees receipt of such shall not constitute
constructive knowledge of any information contained therein or determinable
from information contained therein, including the Managers or Issuers
compliance with any of its representations, warranties or covenants under this
Indenture or any of the Related Documents (as to which the Indenture Trustee is
entitled to rely exclusively on Officers Certificates).  Section 903.           Indenture Trustee Not Liable.  (a)  The recitals contained herein
(other than the representations and warranties contained in Section 911
hereof), in any Supplement and in the Notes (other than the certificate of
authentication on the Notes) shall be taken as the statements of the Issuer,
and the Indenture Trustee assumes no responsibility for their correctness.  The Indenture Trustee makes no
representations as to the validity or sufficiency of this Indenture, any
Supplement, the Notes, the Collateral or of any related document.  The Indenture Trustee shall not be
accountable for the use or application by the Issuer of any of the Notes or of
the proceeds thereof, or for the use or application of any funds paid to the
Issuer or the Manager in respect of the Collateral.  (b)      The Indenture Trustee
shall have no responsibility or liability for or with respect to the existence
or validity of any Owner Compressor, the perfection of any security interest
(whether as of the date hereof or at any future time), the maintenance of or
the taking of any action to maintain such perfection, the validity of the
assignment of any portion of the Collateral to the Indenture Trustee or of any
intervening assignment, the compliance by any Universal Affiliate with any
covenant or the breach by any Universal Affiliate of any warranty or
representation made hereunder, in any Supplement or in any related document or
the accuracy of such warranty or representation, any  66


investment
of monies in the Trust Account or any Series Account or any loss resulting
therefrom (provided that such
investments are made in accordance with the provisions of Section 303 hereof),
or the acts or omissions of the Manager taken in the name of the Indenture
Trustee.  (c)      Except as expressly
provided herein or in any Supplement, the Indenture Trustee shall not have any
obligation or liability under any Contract by reason of or arising out of this
Indenture or the granting of a security interest in such Contract hereunder or
the receipt by the Indenture Trustee of any payment relating to any Contract
pursuant hereto, nor shall the Indenture Trustee be required or obligated in
any manner to perform or fulfill any of the obligations of the Issuer or the
Manager under or pursuant to any Contract, or to make any payment, or to make
any inquiry as to the nature or the sufficiency of any payment received by it,
or the sufficiency of any performance by any party, under any Contract.  Section 904.           Indenture Trustee May Own Notes.  The Indenture Trustee in its individual or
any other capacity may become the owner or pledgee of Notes with the same
rights it would have if it were not the Indenture Trustee; provided that such transaction shall not
result in the disqualification of the Indenture Trustee for purposes of Rule
3a-7 under the Investment Company Act of 1940.  Section 905.           Indenture Trustees Fees and
Expenses.  The fees (Indenture
Trustees Fees) of the Indenture Trustee shall be paid by the Issuer in
accordance with Section 302 hereof in an amount equal to $12,000 per year.  In addition, on the Closing Date, the Issuer
shall pay to the Indenture Trustee an up-front fee equal to $7,500 plus
reasonable attorneys fees.  Subject to
the provisions of Section 902(iii) hereof, the Issuer shall, to the extent not
paid by the Manager, indemnify the Indenture Trustee and each of its officers,
directors and employees for, and hold them harmless against, (i) any loss,
liability, damage claim or expense (including attorneys fees and expenses)
incurred without negligence or willful misconduct on their part, arising out of
or in connection with the acceptance or administration of this trust, including
the costs and expenses of defending itself both individually and in its
representative capacity against any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder and (ii) any
loss, liability or expense directly or indirectly incurred as a result of any
penalty or other cost imposed by the Internal Revenue Service or other taxing
authority (the amounts described in clauses (i) and (ii) collectively, the Indenture
Trustee Indemnified Amounts).  The obligations of the Issuer
under this Section 905 to compensate the Indenture Trustee, to pay or reimburse
the Indenture Trustee for expenses, disbursements and advances and to indemnify
and hold harmless, the Indenture Trustee shall constitute Outstanding Obligations
hereunder and shall survive the resignation or removal of the Indenture Trustee
and the satisfaction and discharge of this Indenture.  When the Indenture Trustee
incurs expenses or renders services in connection with an Event of Default
specified in Section 801(xi) or Section 801(xii), the expenses and the
compensation for the services are intended to constitute expenses of
administration under any bankruptcy law.  Section 906.           Eligibility Requirements for the
Indenture Trustee.  The Indenture
Trustee hereunder shall at all times be a national banking association or a
corporation, organized and doing business under the laws of the United States
of America or any State, and authorized under such laws to exercise corporate
trust powers.  In addition, the Indenture
Trustee or its parent corporation shall at all times (i) have a combined
capital and surplus of at least $250,000,000, (ii) be subject to
supervision or examination by Federal or state authority and (iii) have a
long-term unsecured senior debt rating of A-2 or better by Moodys Investors
Service, Inc. and a long-term unsecured senior debt rating of A by Standard
& Poors Rating Services and short-term unsecured senior debt rating of P-1
or better by Moodys Investors Service, Inc. and a short-term unsecured senior
debt rating of A-2 by Standard &  67


Poors Rating Services.  If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of such supervising
or examining authority, then, for the purposes of this Section 906, 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
condition so published.  In case at any
time the Indenture Trustee shall cease to be eligible in accordance with the
provisions of this Section, the Indenture Trustee shall resign promptly in the
manner and with the effect specified in Section 907 hereof.  Section 907.           Resignation and Removal of the
Indenture Trustee.  The Indenture
Trustee may at any time resign and be discharged from the trusts hereby created
by giving written notice thereof to the Issuer, the Manager, the Deal Agent,
each Series Enhancer, each Interest Rate Hedge Provider and the
Noteholders.  Upon receiving such notice
of resignation, the Issuer shall promptly appoint a successor trustee by
written instrument, a copy of which original instrument shall be delivered to
the resigning Indenture Trustee and the successor Indenture Trustee.  A copy of the instrument shall also be
delivered to the Deal Agent.  If no
successor Indenture Trustee shall have been so appointed and have accepted
appointment within 90 days after the giving of such notice of resignation, the
Requisite Global Majority may appoint a successor trustee or, if it does not do
so within 30 days thereafter, the resigning Indenture Trustee may petition at
the expense of the Issuer any court of competent jurisdiction for the
appointment of a successor trustee, which successor trustee shall meet the
eligibility standards set forth in Section 906.  If at any time the Indenture
Trustee shall cease to be eligible in accordance with the provisions of Section
906 hereof and shall fail to resign after written request therefor by the
Issuer, any Series Enhancer or the Manager, or if at any time the Indenture
Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Indenture Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Indenture
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then the Issuer shall remove the Indenture Trustee
and appoint a successor Indenture Trustee by written instrument, in duplicate,
one copy of which original instrument shall be delivered to the Indenture
Trustee so removed and one copy to the successor Indenture Trustee.  Any resignation or removal of
the Indenture Trustee and appointment of a successor trustee pursuant to any of
the provisions of this Section shall become effective upon, and only upon,
acceptance of appointment by the successor trustee as provided in Section 908
hereof.  Section 908.           Successor Indenture Trustee.  Any successor Indenture Trustee appointed as
provided in Section 907 hereof shall execute, acknowledge and deliver to the
Issuer and to its predecessor Indenture Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Indenture Trustee shall become effective and such successor
Indenture Trustee, without any further act, deed or conveyance, shall become
fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as the Indenture
Trustee herein.  The predecessor
Indenture Trustee shall upon payment of all charges due it, its agents and
counsel deliver to the successor Indenture Trustee all documents relating to
the Collateral, if any, delivered to it, together with any amount remaining in
the Trust Account, and any other Series Accounts.  In addition, the predecessor Indenture
Trustee and, upon request of the successor Indenture Trustee, the Issuer shall
execute and deliver such instruments and do such other things as may reasonably
be required for more fully and certainly vesting and confirming in the
successor Indenture Trustee all such rights, powers, duties and obligations.  No successor Indenture Trustee
shall accept appointment as provided in this Section unless at the time of such
acceptance such successor Indenture Trustee shall be eligible under the  68


provisions of
Section 906 hereof and the Requisite Global Majority has not objected to such
appointment within ten (10) days.  Upon acceptance of appointment
by a successor Indenture Trustee as provided in this Section, the Issuer shall
mail notice of the succession of such Indenture Trustee hereunder to each
Interest Rate Hedge Provider and to all Noteholders at their addresses as shown
in the registration books maintained by the Indenture Trustee.  If the Issuer fails to mail such notice
within 10 days after acceptance of appointment by the successor Indenture
Trustee, the successor Indenture Trustee shall cause such notice to be mailed
at the expense of the Issuer.  Section 909.           Merger or Consolidation of the
Indenture Trustee.  Any entity into
which the Indenture Trustee may be merged or converted or with which it may be
consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Indenture Trustee shall be a party, or any entity
succeeding to the business of the Indenture Trustee, shall be the successor of
the Indenture Trustee hereunder, provided such entity shall be eligible under
the provisions of Section 906 hereof, without the execution or filing of any
paper, deed or conveyance or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding.  Section 910.           Separate Indenture Trustees,
Co-Indenture Trustees and Custodians. 
If the Indenture Trustee is not capable of acting outside the United
States, it shall have the power from time to time to appoint one or more
Persons or corporations to act either as co-trustees jointly with the Indenture
Trustee, or as separate trustees, or as custodians, for the purpose of holding
title to, foreclosing or otherwise taking action with respect to any of the
Collateral, when such separate trustee or co-trustee is necessary or advisable
under any Applicable Laws or for the purpose of otherwise conforming to any
legal requirement, restriction or condition in any applicable
jurisdiction.  The separate trustees,
co-trustees, or custodians so appointed shall be trustees, co-trustees, or
custodians for the benefit of all Noteholders and each Interest Rate Hedge
Provider, and shall have such powers, rights and remedies as shall be specified
in the instrument of appointment; provided,
however, that no such appointment shall, or shall be deemed to,
constitute the appointee an agent of the Indenture Trustee.  The Issuer shall join in any such
appointment, but such joining shall not be necessary for the effectiveness of
such appointment.  Every separate
trustee, co-trustee and custodian shall, to the extent permitted by law, be
appointed and act subject to the following provisions and conditions:  (i)            all powers, duties,
obligations and rights conferred upon the Indenture Trustee in respect of the
receipt, custody and payment of moneys shall be exercised solely by the
Indenture Trustee;  (ii)           all other rights,
powers, duties and obligations conferred or imposed upon the Indenture Trustee
shall be conferred or imposed upon and exercised or performed by the Indenture
Trustee and such separate trustee, co-trustee, or custodian jointly, except to
the extent that under any law of any jurisdiction in which any particular act
or acts are to be performed the Indenture Trustee shall be incompetent or

duties and obligations (including the holding of title to the Collateral or any
portion thereof in any such jurisdiction) shall be exercised and performed by
such separate trustee, co-trustee or custodian;  (iii)          no trustee or
custodian hereunder shall be personally liable by reason of any act or omission

(iv)          the Issuer or the
Indenture Trustee may at any time accept the resignation of or remove any
separate trustee, co-trustee or custodian so appointed by it or them if such
resignation or removal does not violate the other terms of this Indenture.  Any notice, request or other
writing given to the Indenture Trustee shall be deemed to have been given to
each of the then separate trustees and co-trustees, as effectively as if given
to each of them.  Every instrument
appointing any separate trustee, co-trustee, or custodian shall refer to this
Indenture and the conditions of this Article. 
Each separate trustee and co-trustee, upon its acceptance of the trusts
conferred, shall be vested with the estates or property specified in its
instrument of appointment, either jointly with the Indenture Trustee or
separately, as may be provided therein, subject to all the provisions of this
Indenture, specifically including every provision of this Indenture relating to
the conduct of, affecting the liability of, or affording protection to, the
Indenture Trustee.  Every such instrument

co-trustees, or custodian may, at any time, constitute the Indenture Trustee,
its agent or attorney-in-fact, with full power and authority, to the extent not
prohibited by law, to do any lawful act under or in respect of this Indenture
on its behalf and in its name.  If any
separate trustee, co-trustee, or custodian shall die, become incapable of
acting, resign or be removed, all of its estates, properties, rights, remedies
and trusts shall vest in and be exercised by the Indenture Trustee, to the
extent permitted by law, without the appointment of a new or successor trustee
or custodian.  No separate trustee, co-trustee
or custodian hereunder shall be required to meet the terms of eligibility as
successor trustee under Section 906 hereof and no notice to Noteholders of the
appointment thereof shall be required under Section 908 hereof.  The Indenture Trustee agrees to
instruct the co-trustees, if any, to the extent necessary to fulfill the
Indenture Trustees obligations hereunder.  Section 911.           Representations and Warranties.  The Indenture Trustee hereby represents and

trust companies in particular and (ii) the remedy of specific performance
and injunctive and other forms of equitable relief may be subject to certain
equitable defenses and to the discretion of the court before which any

(d)      No Violation.  The performance by the Indenture Trustee of
its obligations under this Indenture and each Supplement will not conflict
with, result in any breach of any of the terms and provisions of, or constitute
(with or without notice, lapse of time or both) a default under, the charter
documents or bylaws of the Indenture Trustee;  (e)      No Proceedings.  There are no proceedings or investigations to
which the Indenture Trustee is a party pending, or, to the knowledge of the

Authority (A) asserting the invalidity of this Indenture or the Notes,
(B) seeking to prevent the issuance of the Notes or the consummation of
any of the transactions contemplated by this Indenture or (C) seeking any
determination or ruling that would materially and adversely affect the
performance by the Indenture Trustee of its obligations under, or the validity
or enforceability of, this Indenture or the Notes;  (f)       Approvals.  Neither the execution or delivery by the
Indenture Trustee of this Indenture nor the consummation of the transactions by
the Indenture Trustee contemplated hereby requires the consent or approval of,
the giving of notice to, the registration with or the taking of any other
action with respect to any Governmental Authority under any existing federal or
State of Minnesota law governing the banking or trust powers of the Indenture
Trustee;  (g)      Control of Indenture

Provider, the Deal Agent and the Contributor if it at any time it becomes

Claims.  Wells Fargo Bank, National
Association does not have any knowledge of adverse claim with respect to the

any order, writ, judgment, injunction, decree, determination or award of any

lapse of time or both) a default under this Indenture, the Related Documents,
any other indenture or other loan or credit agreement, or other agreement or
instrument to which Indenture Trustee is a party or by which Indenture Trustee,
or its property and assets may be bound or affected that could result in a
Material Adverse Change or result in a Lien on any Collateral other than

default under any law, rule, regulation, order, writ, judgment, injunction,
decree, determination or award or any contract, agreement, lease, license,
indenture or other instrument to which it is a party that could result in a
Material Adverse Change; and  (j)       Compliance with Law. 
The Indenture Trustee:  (i)            is not in violation
of (1) any laws, ordinances, governmental rules or regulations, or (2) court

interests of the Noteholders, any Series Enhancer or Eligible Interest Rate
Hedge Counterparty in any Collateral.  Section 912.           Indenture Trustee Offices.  The Indenture Trustee shall maintain in the

(5) Business Days) give written notice thereof to each Noteholder, each
Interest Rate Hedge Provider and any Rating Agency and Series Enhancer of such
Series.  For all purposes of this
Indenture, in the absence of actual knowledge by a Corporate Trust Officer of

Indenture Trustee a certificate stating that all conditions precedent, if any,
provided for in this Indenture and any relevant Supplement relating to the
proposed action have been complied with and, if deemed reasonably necessary by
the Indenture Trustee or if required pursuant to the terms of this Indenture,
an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.  (b)      Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:  (i)            a statement that,
in the opinion of each such individual, he has made such examination or

Indenture Trustee.  (a)  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.  (b)      Any certificate or

required to make, give or execute two or more applications, requests, consents,

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 Indenture
Trustee deems sufficient.  (c)      The ownership of Notes
shall be proved by the Note Register.  (d)      Any request, demand,
authorization, direction, notice, consent, waiver or other Act of the Holder of

not notation of such action is made upon such Note.  Section 1204.         Inspection.  The Requisite Global Majority shall have the

whether pursuant to a judgment or otherwise,
except to the extent actually received by the Person entitled thereto and
converted into Dollars by such Person (it being understood and agreed that, if
any transaction party shall so receive an amount in a currency other than
Dollars, it shall (A) if it is not the Person entitled to receive payment,
promptly return the same (in the currency in which received) to the Person from
whom it was received or (B) if it is the Person entitled to receive
payment, either, in its sole discretion, (x) promptly return the same (in
the currency in which received) to the Person from whom it was received or (y) subject
to reasonable commercial practices, promptly cause the conversion of the same
into Dollars), (iv) to the extent that the amount so paid on prompt
conversion to Dollars under normal commercial practices does not yield the
requisite amount of Dollars, the obligee of such payment shall have a separate
cause of action against the party obligated to make the relevant payment for
the additional amount necessary to yield the amount due and owing under the
Related Documents, (v) if, for the purpose of obtaining a judgment in any
court with respect to any obligation under any of the Related Documents, it
shall be necessary to convert to any other currency any amount in Dollars due
thereunder and a change shall occur between the rate of exchange applied in
making such conversion and the rate of exchange prevailing on the date of
payment of such judgment, the obligor in respect of such obligation will pay
such additional amounts (if any) as may be necessary to insure that the amount
paid on the date of payment is the amount in such other currency which, when
converted into Dollars and transferred to New York City, New York, in accordance
with normal banking procedures, will result in realization of the amount then
due in Dollars and (vi) any amount due under this paragraph shall be due
as a separate debt and shall not be affected by or merged into any judgment
being obtained for any other sum due under or in respect of the Related
Documents.  In no event, however, shall
the respective judgment debtor be required to pay a larger amount in such other
currency, at the rate of exchange in effect on the date of payment than the
amount of Dollars stated to be due under the respective Related Document, so
that in any event the obligations of the respective judgment debtor under the
Related Document will be effectively maintained as Dollar obligations.  Section 1216.         Assignment of Rights of a Series
Enhancer.  During the continuation of
a Series Enhancer Default with respect to any Series Enhancer, all of the
rights and privileges (but none of the duties or obligations) of such Series
Enhancer hereunder or under the Related Documents shall vest in the related
Control Party for the applicable Series).  Section 1217.         Limitation on Payment.  Any amounts payable by the Issuer hereunder are
contingent upon the availability of funds to make each payment in accordance

not constitute a Claim (as defined in Section 101(5) of the Bankruptcy Code)
against the Issuer in any bankruptcy, reorganization, arrangement, insolvency
or liquidation proceedings involving the Issuer.  [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK  SIGNATURE
