<PAGE>   11

declares that the Indenture Trustee holds and will hold such right, title and
interest for the benefit of all present and future Noteholders for the use and
purpose and subject to the terms and provisions of this Indenture. The Trust
hereby (a) appoints the Indenture Trustee as the Trust's attorney-in-fact with

                  Section 2.05 Liabilities of the Trust and Parties to this
Indenture; Limitations Thereon. (a) The obligations evidenced by the Notes
provide recourse only to the Pledged Property and provide no recourse against
SierraCities.com, the Depositor, the Servicer, the Indenture Trustee, the Owner
Trustee or any other Person, except as set forth in paragraph (b) below and as
may be set forth in the Transaction Documents.

                  (b) Neither SierraCities.com, the Trust, the Depositor, the
Servicer nor any other Person shall be liable to the Indenture Trustee or the
Noteholders except as provided in Article VI hereof and Sections 5.01, 5.03, and
5.07 of the Servicing Agreement and Section 4.01(g) of the Receivables Transfer
Agreement. Without limiting the generality of the foregoing, if any Obligor

Payment, Final Scheduled Payment, other amounts due under the Contract or any

                  (c) The Indenture Trustee agrees that in the event of a

specified herein. In addition, the Indenture Trustee shall have the right to
exercise the rights of SierraCities.com under the Contracts, the Insurance
Policies and any document in any Contract File in the name of the Indenture
Trustee and the Noteholders, either directly or through the Servicer as agent,
and the Indenture Trustee is hereby directed by the Trust to exercise such
rights; provided, however, that the Indenture Trustee shall not be required to
take any action pursuant to this Section 2.05(c) except upon written
instructions from the Servicer. A carbon, photographic or other reproduction of
this Indenture or any financing statement is sufficient as a financing statement
in any State.

                  (d) The pledge of the Pledged Property by the Trust pursuant
to this Indenture does not constitute and is not intended to result in an
assumption by the Indenture Trustee, the Trust or any Noteholder of any
obligation (except for the obligation not to disturb an Obligor's right of quiet
enjoyment) of SierraCities.com or the Servicer to any Obligor or other Person in
connection with the Equipment, the Contracts, the Insurance Policies or any
document in the Contract Files.

                  Section 2.06 Intended Tax Characterization. The parties hereto
agree that it is their mutual intent that, for all applicable tax purposes, the
Class A Notes and the Class B

                                       5
<PAGE>   12

Notes will constitute indebtedness and that for all applicable tax purposes,
accordingly, the Trust will be treated as sole and exclusive owner of the
Pledged Property. Further, each party hereto and each Noteholder (by receiving
and holding a Note), hereby covenants to every other party hereto and to every
other Noteholder to treat the Class A Notes and the Class B Notes as
indebtedness for all applicable tax purposes in all tax filings, reports and
returns and otherwise, and further covenants that neither it nor any of its
Affiliates will take, or participate in the taking of or permit to be taken, any
action that is inconsistent with the treatment of the Class A Notes or of the
Class B Notes as indebtedness for tax purposes. All successors and assigns of
the parties hereto shall be bound by the provisions hereof.

                  Section 2.07 Treasury Securities. In determining whether the
Noteholders of the required outstanding principal balance of the Notes have
concurred in any direction, waiver or consent, Notes owned by SierraCities.com,
any other obligor upon the Notes or any Affiliate of SierraCities.com shall be
considered as though not outstanding, except that for the purposes of
determining whether the Indenture Trustee shall be protected in relying on any
such direction, waiver or consent, only Notes which a Responsible Officer
actually knows are so owned shall be so disregarded.

election, any earlier date), SierraCities.com shall deposit (or cause to be
deposited) to the Collection Account the Repurchase Amount with respect to such
Contract or replace such contract with a Substitute Contract pursuant to Section
4.02 hereof. Any such nonconforming Contract so removed shall not be deemed to

                  (b) The obligation of SierraCities.com to remove any Pledged
Property from the Trust and to remit the Repurchase Amount or substitute a
Substitute Contract, as appropriate, with respect to the related Contract as to
which a breach has occurred and is continuing shall constitute the sole remedy
against SierraCities.com for such breach available to the Indenture Trustee and
the Noteholders, except to the extent that such breach is the result of any
fraud or willful misconduct on the part of SierraCities.com.

                  (c) Upon the removal of a Contract and the related Equipment
and the payment of the related Repurchase Amount as described above, the
security interest of the Indenture Trustee in such replaced Contract, the
related Equipment and all proceeds thereon shall be terminated and the replaced
Contract and the related Equipment shall be released to the Trust.

                  Section 4.02 Substitution of Contracts. (a) Subject to the

Substitute Contracts reflecting the substitution, and (iv) delivering to the
Indenture Trustee a release request, in form and substance acceptable to the
Indenture Trustee, with respect to the Contract being replaced and the
originally executed trust receipt relating thereto.

                  (d) No such substitution under this Section 4.02 shall be
permitted on any Substitute Transfer Date if:

                           (i) on a cumulative basis from the related Cut-Off
         Date, the sum of the Aggregate Discounted Contract Balances (as of the
         related Substitute Cut-Off Date) of such Substitute Contracts would
         equal or exceed ten percent (10%) of the sum of the Aggregate
         Discounted Contract Balance of all Contracts as of the related Cut-Off
         Dates;

                           (ii) as of the related Substitute Cut-Off Date, the
         Substitute Contracts then being transferred have a Discounted Contract
         Balance less than the Discounted Contract Balance of the Contracts
         being replaced or have a maturity date later than the latest maturity
         date of any Contract then held by the Trust; and

                           (iii) as a result thereof, (x) the sum of the
         Scheduled Payments on all Contracts due in any Collection Period
         thereafter would be less than or increase the amount by which it is
         less than (y) the sum of the Scheduled Payments which would otherwise
         be due in such Collection Period.

                  For purposes of determining compliance with clause (ii), if
more than one Substitute Contract is being provided on any date, the Discounted
Contract Balance of the Substitute Contracts and the Contracts being replaced
shall be determined on an aggregate basis.

                  (e) Upon the replacement of a Contract and the related
Equipment with a Substitute Contract as described above, the security interest
of the Indenture Trustee in such replaced Contract, the related Equipment and

relying upon an instrument executed by the Indenture Trustee as provided in this
Article IV 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.

                  (b) The Indenture Trustee shall, at such time as there are no
Notes outstanding and all sums due the Indenture Trustee have each been paid,
release any remaining portion of the Pledged Property that secured the Note from
the lien of this Indenture and release to the Trust or any other Person entitled
thereto any funds then on deposit in the Collection Account or any subaccounts
thereof as may have been established pursuant to Sections 3.01 and 3.02. The
Indenture Trustee shall release property from the lien of this Indenture
pursuant to this Section 4.04(b) only upon receipt of an Issuer Request
accompanied by an Officer's Certificate, an Opinion of Counsel and (if required
by the TIA) Independent Certificates in accordance with TIA Sections 314(c) and
314(d)(1) meeting the applicable requirements of Section 10.05 hereof.

                                   ARTICLE V.

                                    THE NOTES

                  Section 5.01 The Notes. (a) The Class A Notes will be issued
in denominations of $1,000 and multiples of $1,000 in excess thereof (with the
exception of one Note of each class which will be issued in an odd amount) of
the Initial Class A-1 Note Principal Balance, the Initial Class A-2 Note
Principal Balance, and the Class B Notes will be issued in denominations of
$1,000,000 and $1,000 increments above $1,000,000 of the Initial Class B Note
Principal Balance. Each Note shall represent a validly issued and binding
obligation of the Trust, but only if such Note has been executed on behalf of
the Trust by a Responsible Officer of the Owner Trustee by manual signature, and
authenticated on behalf of the Indenture Trustee by a Responsible Officer of the
Indenture Trustee by manual signature. Each Note bearing the manual signatures
of individuals who were, at the time when such signatures were affixed,
authorized to sign on behalf of the Trust shall be valid and binding
obligations, notwithstanding that such individuals or any of them have ceased to
be so authorized prior to the authentication and delivery of such Note or did
not hold such offices at the date of such Note. No Note shall be entitled to any
benefit under this Indenture, or be valid for any purpose, unless there appears
on such Note a certificate of authentication substantially in the form set forth
in the form of the Notes of the related Class, each attached as Exhibits hereto,
signed by the Indenture Trustee by manual signature, and such signature upon any
Note shall be conclusive evidence, and the only evidence, that such Note has
been duly authenticated and delivered hereunder. All Class A-1 Notes and Class
A-2 Notes shall be substantially in the forms set forth in Exhibits C-1 and C-2
hereto, respectively, all Class B Notes shall be substantially in the form set
forth in Exhibit D-1 hereto. Each Note shall be dated the date of its
authentication. Neither the Notes nor the

                                       17
<PAGE>   24

Contracts are insured by the Federal Deposit Insurance Corporation or any other
governmental agency.

                  (b) It is intended that the Notes be registered so as to
participate in a global book-entry system with the Trust, as set forth herein.
The Notes shall, except as otherwise provided in the next paragraph, be
initially issued in the form of a single fully registered Class A-1 Note, Class
A-2 Note, and Class B Note, each with a denomination equal to the Initial Class
A-1 Note Principal Balance, the Initial Class A-2 Note Principal Balance, and
the Initial Class B Note Principal Balance, respectively. Upon initial issuance,
the ownership of each such Note shall be registered in the Register in the name
of Cede & Co., or any successor thereto, as nominee for the Trustee.

                  The Trust and the Indenture Trustee are hereby authorized to
execute and deliver the Representation Letter with the Depository.

                  With respect to Notes registered in the Register in the name
of Cede & Co., as nominee of the Depository, the Trust and the Indenture Trustee
shall have no responsibility or obligation to Direct or Indirect Participants or
beneficial owners for which the Depository holds Notes from time to time as a
trustee. Without limiting the immediately preceding sentence, the Trust, the
Servicer and the Indenture Trustee shall have no responsibility or obligation
with respect to (i) the accuracy of the records of the Depository, Cede & Co.,
or any Direct or Indirect Participant with respect to any ownership interest in
any Note, (ii) the delivery to any Direct or Indirect Participant or any other
Person, other than a Noteholder, of any notice with respect to the Notes or
(iii) the payment to any Direct or Indirect Participant or any other Person,
other than a Noteholder, of any amount with respect to any distribution of
principal or interest on the Notes. No Person other than a Noteholder shall
receive a certificate evidencing such Note.

                  Upon delivery by the Depository to the Indenture Trustee of
written notice to the effect that the Depository has determined to substitute a
new nominee in place of Cede & Co., and subject to the provisions hereof with
respect to the payment of interest by the mailing of checks or drafts to the
Noteholders appearing as Noteholders at the close of business on a Record Date,
the name "Cede & Co." in this Indenture shall refer to such new nominee of the
Depository.

                  (c) In the event that (i) the Depository or the Servicer
advises the Indenture Trustee in writing that the Depository is no longer
willing or able to discharge properly its responsibilities as nominee and
depository with respect to the Notes and the Servicer or the Depository is
unable to locate a qualified successor or (ii) the Indenture Trustee at its sole
option elects to terminate the book-entry system through the Depository, the
Notes shall no longer be restricted to being registered in the Register in the
name of Cede & Co. (or a successor nominee) as nominee of the Depository. At
that time, the Servicer may determine that the Notes shall be registered in the
name of and deposited with a successor depository operating a global book-entry
system, as may be acceptable to the Servicer, or such depository's agent or
designee but, if the Servicer does not select such alternative global book-entry
system, then the Notes may be registered in whatever name or names Noteholders
transferring Notes shall designate, in accordance with the provisions hereof;
provided, however, that any such registration shall be at the expense of the
Servicer.

                                       18
<PAGE>   25

                  (d) Notwithstanding any other provision of this Indenture to
the contrary, so long as any Note is registered in the name of Cede & Co., as
nominee of the Depository, all distributions of principal or interest on such
Notes, as the case may be, and all notices with respect to such Notes, as the
case may be, shall be made and given, respectively, in the manner provided in
the Representation Letter.

                  In the event any Notes are issued in book-entry form with the
Depository: (i) the Indenture Trustee may deal with the Depository as the
authorized representative of the Noteholders; (ii) the rights of the Noteholders
shall be exercised only through the Depository and shall be limited to those
established by law and agreement between the Noteholders and the Depository;
(iii) the Depository will make book-entry transfers among the direct
participants of the Depository and will receive and transmit distributions of
principal and interest on the Notes to such direct participants; and (iv) the
direct participants of the Depository shall have no rights under this Indenture
under or with respect to any of the Notes held on their behalf by the
Depository, and the Depository may be treated by the Indenture Trustee and its
agents, employees, officers and directors as the absolute owner of the Notes for
all purposes whatsoever.

                  Section 5.02 Initial Issuance of Notes. The Indenture Trustee
shall, upon the written instruction of the Trust, in exchange for the Pledged
Property, authenticate and deliver the Class A Notes and the Class B Notes
executed by the Trust in authorized denominations equaling in the aggregate the
Initial Class A Note Principal Balance and the Initial Class B Note Principal
Balance.

                  Section 5.03 Registration of Transfer and Exchange of Notes.
(a) The Indenture Trustee, as initial Note Registrar, shall maintain, or cause
to be maintained, at the Corporate Trust Office, a register (the "Register") in
which the Indenture Trustee shall provide for the registration of Notes and of
transfers and exchanges of Notes as herein provided. All Notes shall be so
registered.

                  (b) Upon surrender for registration of transfer of any Note at
the Corporate Trust Office, the Trust shall execute, and the Indenture Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes in authorized denominations of the same
class, of a like aggregate Class A-1 Percentage Interest, Class A-2 Percentage
Interest, and Class B Percentage Interest, as the case may be, dated the date of
such authentication.

                  (c) At the option of a Noteholder, Notes may be exchanged for
other Notes of the same class (of authorized denominations in the case of Class
A Notes and Class B Notes) of a like aggregate Class A-1 Percentage Interest,
Class A-2 Percentage Interest, and Class B Percentage Interest, as the case may
be, upon surrender of the Notes to be exchanged at any such office or agency.
Whenever any Notes are so surrendered for exchange, the Trust shall execute, and
the Indenture Trustee shall authenticate and deliver the Notes that the
Noteholder making the exchange is entitled to receive.

                  (d) No service charge shall be made for any registration of
transfer of any Note or for the exchange of any Note, but the Indenture Trustee
may require payment of a sum

                                       19
<PAGE>   26

sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer of any Note or exchange of any Note.

                  (e) All Notes surrendered for registration of transfer and all
Notes surrendered for exchange shall be delivered to the Indenture Trustee and
cancelled and subsequently destroyed by the Indenture Trustee in accordance with
its customary practices in effect from time to time.

                  (f) The Note Registrar shall not register the transfer of any
Note (other than the transfer of a Note to the nominee of the Depository or a
successor depository) unless the transferee has executed and delivered to the
Indenture Trustee a certification to the effect that either (i) the transferee
is not (A) an employee benefit plan (as defined in Section 3(3) of ERISA) that
is subject to the provisions of Title I of ERISA or (B) a plan (as defined in
Section 4975(e)(1) of the Code) that is subject to Section 4975 of the Code
(each of the foregoing, a "Benefit Plan"), and is not acting on behalf of or
investing the assets of a Benefit Plan, or (ii) that the transferee's
acquisition and continued holding of the Note will be entitled to exemptive
relief pursuant to a U.S. Department of Labor prohibited transaction class
exemption. Each transferee of a beneficial interest in a Note that is registered
in the name of, and deposited with, a depository operating a global book-entry
system shall be deemed to make one of the foregoing representations.

                  Section 5.04 Mutilated, Destroyed, Lost or Stolen Notes. If
any mutilated Note is surrendered to the Indenture Trustee, or the Indenture
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, and (a) there is delivered to the Trust, the Owner Trustee, the
Servicer and the Indenture Trustee such security or indemnity satisfactory to
each of them as may be required by them to save each of them harmless, then, in
the absence of notice to the Indenture Trustee that any such Note has been
acquired by a bona fide purchaser, the Trust 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 new Note of like Class and
Percentage Interest. In connection with the issuance of any new Note under this
Section 5.04, the Indenture Trustee may require the payment by the Noteholder of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto. Any other expenses (including the fees and expenses
of the Indenture Trustee) in connection therewith shall be paid by the Servicer.
Any duplicate Note issued pursuant to this Section 5.04 shall constitute a Note
duly issued by the Trust, as if originally issued, whether or not the lost,
stolen or destroyed Note shall be found at any time.

                  Section 5.05 Persons Deemed Owners. The Indenture Trustee may
treat the Person in whose name any Note is registered as the owner of such Note
for the purpose of receiving distributions pursuant to Section 3.05 hereof and
for all other purposes whatsoever, and the Indenture Trustee shall not be
affected by any notice to the contrary.

                  Section 5.06 Access to List of Noteholders' Names and
Addresses. (a) The Indenture Trustee will furnish or cause to be furnished to
the Servicer within 15 days after receipt by the Indenture Trustee of a request
therefor from the Servicer in writing, a list of the names and addresses of the
Noteholders as of the most recent Record Date. If one or more Noteholders
representing a Class A Percentage Interest or a Class B Percentage Interest of
not

                                       20
<PAGE>   27

less than 25% (an "Applicant") shall apply in writing to the Indenture Trustee,
and such application shall state that the Applicant desires to communicate with
other Noteholders with respect to its rights under this Indenture or under the
Notes, then the Indenture Trustee shall, within five Business Days after the
receipt of such application, send such notice to the current list of
Noteholders. Every Noteholder, by receiving and holding a Note, agrees with the
Trust, the Owner Trustee, the Servicer and the Indenture Trustee that none of
the Trust, the Owner Trustee, the Servicer nor the Indenture Trustee shall be
held accountable by reason of the disclosure of any such information, regardless
of the source from which such information was derived.

                  Section 5.07 Acts of Noteholders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Noteholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Noteholders in person or by an agent duly appointed in writing, and, except
as herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Indenture Trustee and, where
required, to the Trust or the Servicer. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 7.01 hereof) conclusive in
favor of the Indenture Trustee, the Trust, SierraCities.com and the Servicer, if
made in the manner provided in this Section 5.07.

                  (b) The fact and date of the execution by any Noteholder of
any such instrument or writing may be proven in any reasonable manner which the
Indenture Trustee deems sufficient.

                  (c) The ownership of Notes shall be proven by the Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other act by a Noteholder shall bind every holder of every
Note issued upon the registration of transfer thereof or in exchange therefor or
in lieu thereof, in respect of anything done or omitted to be done by the
Indenture Trustee, the Owner Trustee, the Trust or the Servicer in reliance
thereon, whether or not notation of such action is made upon such Note.

                  Section 5.08 No Proceedings. By its acceptance of a Note, each
Noteholder shall be deemed to have agreed that it will not directly or
indirectly institute, or cause to be instituted, against the Trust Certificate
Holder or the Trust any bankruptcy or insolvency proceeding so long as there
shall not have elapsed one year plus one day since the maturity date of the
latest maturing securities of the Trust.

                                   ARTICLE VI.

                                    THE TRUST

                  Section 6.01 Liability of the Trust. The Trust shall be liable
for payments in respect of the Notes in accordance herewith only to the extent
of the obligations specifically undertaken by the Trust herein.

                                       21
<PAGE>   28

                  Section 6.02 Limitation on Liability of the Trust. Neither the
Owner Trustee nor the directors, officers, employees or agents of the Trust or
the Owner Trustee shall be under any liability to the Indenture Trustee, the
Noteholders, SierraCities.com, the Servicer, the Trust Certificate Holder or any
other Person hereunder or pursuant to any document delivered hereunder, it being
expressly understood that all such liability is expressly waived and released as
a condition of, and as consideration for, the Trust's execution and delivery of
this Indenture and the issuance of the Notes. The Trust shall not be under any
liability to the Indenture Trustee, the Noteholders, SierraCities.com, the
Servicer, the Trust Certificate Holder or any other Person for any action taken
or for refraining from the taking of any action in its capacity as Trust
pursuant to this Indenture whether arising from express or implied duties under
this Indenture; provided, however, that this provision shall not protect the
Trust against any liability which would otherwise be imposed by reason of
willful misfeasance, bad faith, misrepresentation or gross negligence in the
performance of duties or by reason of reckless disregard of obligations and
duties hereunder. The Trust may rely in good faith on any document of any kind
prima facie properly executed and submitted by any other Person respecting any
matters arising hereunder.

                  Section 6.03 Indemnity for Liability Claims. The Trust
Certificate Holder on behalf of the Trust shall be deemed to have agreed to
indemnify, defend and hold harmless the Indenture Trustee (which shall include
any of its directors, employees, officers and agents), the Owner Trustee (which
shall include any of its directors, employees, officers and agents), the
Noteholders against and from any and all costs, expenses, losses, damages,
claims and liabilities arising out of or resulting from the use, repossession or
operation of the Equipment to the extent not covered by the Servicer's indemnity
provided by Section 5.01 of the Servicing Agreement; provided, however, that
such amounts shall be payable solely from amounts payable to the Trust
Certificate Holder pursuant to Section 3.05(b)(xii) hereof.

                  Section 6.04 Liabilities. Notwithstanding any provision of
this Indenture, by entering into this Indenture, the Trust and the Trust
Certificate Holder agrees to be liable, directly to the injured party, for the
entire amount of any losses, claims, damages or liabilities (other than those
losses incurred by a Class A Noteholder or a Class B Noteholder in the capacity
of an investor in the Class A Notes or the Class B Notes) imposed on or asserted
against the Trust or otherwise arising out of or based on the arrangements
created by this Indenture (to the extent of the Trust assets remaining after the
Class A Noteholders and the Class B Noteholders have been paid in full are
insufficient to pay such losses, claims, damages or liabilities).

                  Section 6.05 [Reserved.]

                  Section 6.06. Annual Statement as to Compliance. The Servicer
on behalf of the Trust will deliver to the Indenture Trustee, within 90 days
after the end of each fiscal year of the Trust (commencing with the fiscal year
ended December 31, 2000), and otherwise in compliance with the requirements of
TIA Section 314(a)(4) an Officer's Certificate stating, as to the Authorized
Officer signing such Officer's Certificate, that

                           (i) a review of the activities of the Trust during
         such year and of performance under this Indenture has been made under
         such Authorized Officer's supervision; and

                                       22
<PAGE>   29

                           (ii) to the best of such Authorized Officer's
         knowledge, based on such review, the Trust has complied with all
         conditions and covenants under this Indenture throughout such year, or,
         if there has been a default in the compliance of any such condition or
         covenant, specifying each such default known to such Authorized Officer
         and the nature and status thereof.

                  Section 6.07 Payment of Principal and Interest. The Indenture
Trustee on behalf of the Trust will pay or cause to be duly and punctually paid
the principal of and interest on the Notes in accordance with the terms of the
Notes and this Indenture. Amounts properly withheld under the Code by any Person
from a payment to any Noteholder of interest and/or principal shall be
considered as having been paid by the Trust to such Noteholder for all purposes
of this Indenture.

                  Section 6.08 Maintenance of Office or Agency. The Note
Registrar shall, and the Indenture Trustee, as initial Note Registrar agrees to,
maintain in New York, New York, an office or agency where Notes may be
surrendered for registration of transfer or exchange, and where notices and
demands to or upon the Trust in respect of the Notes and this Indenture may be
served. The Indenture Trustee will give prompt written notice to the Trust of
the location, and of any change in the location, of any such office or agency.

                  Section 6.09 Money for Payments to be Held in Trust. On or
before each Payment Date, the Servicer on behalf of the Trust shall deposit or
cause to be deposited in the Collection Account, but only from the sources
described herein, an aggregate sum sufficient to pay the amounts then becoming
due under the Notes, such sum to be held in trust for the benefit of the Persons
entitled thereto and (unless the paying agent is the Indenture Trustee) shall
promptly notify the Indenture Trustee of its action or failure so to act.

                  The Servicer on behalf of the Trust will cause each paying
agent other than the Indenture Trustee to execute and deliver to the Indenture
Trustee an instrument in which such paying agent shall agree with the Indenture
Trustee (and if the Indenture Trustee acts as paying agent, it hereby so
agrees), subject to the provisions of this Section, that such paying agent will:

                           (i) hold all sums held by it for the payment of
         amounts due with respect to the Notes in trust for the benefit of the
         Persons entitled thereto until such sums shall be paid to such Persons
         or otherwise disposed of as herein provided and pay such sums to such
         Persons as herein provided;

                           (ii) give the Indenture Trustee notice of any default
         by the Trust (or any other obligor upon the Notes) of which it has
         actual knowledge in the making of any payment required to be made with
         respect to the Notes;

                           (iii) at any time during the continuance of any such
         default, upon the written request of the Indenture Trustee, forthwith
         pay to the Indenture Trustee all sums so held in trust by such paying
         agent;

                           (iv) immediately resign as a paying agent and
         forthwith pay to the Indenture Trustee all sums held by it in trust for
         the payment of Notes if at any time it ceases to meet the standards
         required to be met by a paying agent at the time of its appointment;
         and

                                       23
<PAGE>   30

                           (v) comply with all requirements of the Code with
         respect to the withholding from any payments made by it on any Notes of
         any applicable withholding taxes imposed thereon and with respect to
         any applicable reporting requirements in connection therewith.

                  The Trust may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, direct
any paying agent to pay to the Indenture Trustee all sums held in trust by such
paying agent, such sums to be held by the Indenture Trustee upon the same trusts
as those upon which the sums were held by such paying agent; and upon such a
payment by any paying agent to the Indenture Trustee, such paying agent shall be
released from all further liability with respect to such money.

                  Subject to applicable laws with respect to the escheat of
funds, any money held by the Indenture Trustee or any paying agent in trust for
the payment of any amount due with respect to any Note and remaining unclaimed
for two years after such amount has become due and payable shall be discharged
from such trust and be paid to the Trust and shall be deposited by the Indenture
Trustee in the Collection Account; and the Holder of such Note shall thereafter,
as an unsecured general creditor, look only to the Trust for payment thereof
(but only to the extent of the amounts so paid to the Trust), and all liability
of the Indenture Trustee or such paying agent with respect to such trust money
shall thereupon cease; provided, however, that the Indenture Trustee or such
paying agent, before being required to make any such repayment, shall at the
expense of the Trust cause to be published once, in a newspaper published in the
English language, customarily published on each Business Day and of general
circulation in The City of New York, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Trust. The Indenture Trustee shall also adopt
and employ, at the expense of the Trust, any other reasonable means of
notification of such repayment (including, but not limited to, mailing notice of
such repayment to Holders whose Notes have been called but have not been
surrendered for redemption or whose right to or interest in moneys due and
payable but not claimed is determinable from the records of the Indenture
Trustee or of any paying agent, at the last address of record for each such
Holder).

                  Section 6.10 Existence. Except as otherwise permitted by the
provisions of Section 6.13, the Owner Trustee, on behalf of the Trust, will keep
in full effect the Trust's existence, rights and franchises as a common law
trust under the laws of the State of Delaware (unless the Trust becomes, or any
successor Trust hereunder is or becomes, organized under the laws of any other
state or of the United States of America, in which case the Owner Trustee or a
successor Owner Trustee, on behalf of the Trust, will keep in full effect the
Trust's existence, rights and franchises under the laws of such other
jurisdiction) and the Servicer, on behalf of the Trust, will obtain and preserve
the Trust's qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes and each other instrument or
agreement included in the Pledged Property.

<PAGE>   31

                  Section 6.11 Protection of Pledged Property. The Trust intends
the security interest granted pursuant to this Indenture in favor of the
Indenture Trustee and the Noteholders, as their interests appear herein, to be
prior to all other liens in respect of the Pledged Property, and the Servicer on
behalf of the Trust shall take all actions necessary to obtain and maintain, in
favor of the Indenture Trustee, for the benefit of the Noteholders, a first lien
on and a first priority, perfected security interest in the Pledged Property.
The Servicer on behalf of the Trust will from time to time prepare (or shall
cause to be prepared), execute and deliver all such supplements and amendments
hereto and all such financing statements, continuation statements, instruments
of further assurance and other instruments, and will take such other action
necessary or advisable to:

                           (i) grant more effectively all or any portion of the
         Pledged Property;

                           (ii) maintain or preserve the lien and security
         interest (and the priority thereof) in favor of the Indenture Trustee
         for the benefit of the Noteholders, created by this Indenture or carry
         out more effectively the purposes hereof;

                           (iii) perfect, publish notice of or protect the
         validity of any grant made or to be made by this Indenture;

                           (iv) enforce any of the Pledged Property;

                           (v) preserve and defend title to the Pledged Property
         and the rights of the Indenture Trustee in such Pledged Property
         against the claims of all persons and parties; and

                           (vi) pay all taxes or assessments levied or assessed
         upon the Pledged Property when due.

The Trust hereby designates the Indenture Trustee its agent and attorney-in-fact
to execute any financing statement, continuation statement or other instrument
required by the Indenture Trustee pursuant to this Section 6.11.

                  Section 6.12 Performance of Obligations; Servicing of
Receivables. (a) The Trust will not take any action and will use its best
efforts not to permit any action to be taken by others that would release any
Person from any of such Person's material covenants or obligations under any
instrument or agreement included in the Pledged Property or that would result in
the amendment, hypothecation, subordination, termination or discharge of, or
impair the validity or effectiveness of, any such instrument or agreement,
except as ordered by any bankruptcy or other court or as expressly provided in
this Indenture, the other Transaction Documents or any other instrument or
agreement.

                  (b) The Trust may contract with other Persons to assist it in
performing its duties under this Indenture, and any performance of such duties
by a Person identified to the Indenture Trustee in an Officer's Certificate of
the Trust shall be deemed to be action taken by the Trust. Initially, the Trust
has contracted with the Servicer to substantially perform the Trust's duties
under this Indenture, and in such regard, the Trust may rely upon information
provided by

                                       25
<PAGE>   32

the Servicer in connection with any Officer's Certificates of the Trust to be
provided pursuant to this Indenture and any other action to be take by the Trust
pursuant to this Indenture.

                  (c) The Trust will punctually perform and observe all of its
obligations and agreements contained in this Indenture, the other Transaction
Documents and in the instruments and agreements included in the Pledged
Property, including, but not limited to, preparing (or causing to be prepared)
and filing (or causing to be filed) all UCC financing statements and
continuation statements required to be filed by the terms of this Indenture and
the Servicing Agreement in accordance with and within the time periods provided
for herein and therein.

                  (d) If a Responsible Officer of the Owner Trustee shall have
actual knowledge of the occurrence of an Event of Servicing Termination under
the Servicing Agreement, the Trust shall promptly notify the Indenture Trustee
and the Rating Agencies in writing thereof, and shall specify in such notice the
action, if any, the Trust is taking in respect of such default. If an Event of
Servicing Termination shall arise from the failure of the Servicer to perform
any of its duties or obligations under the Servicing Agreement with respect to
the Contracts, the Trust shall take all reasonable steps available to it to
remedy such failure.

                  Section 6.13 Negative Covenants. So long as any Notes are
Outstanding, the Trust shall not:

                           (i) except as expressly permitted by this Indenture
         or the other Transaction Documents, sell, transfer, exchange or
         otherwise dispose of any of the properties or assets of the Trust,
         including those included in the Pledged Property;

                           (ii) claim any credit on, or make any deduction from
         the principal or interest payable in respect of, the Notes (other than
         amounts properly withheld from such payments under the Code) or assert
         any claim against any present or former Noteholder by reason of the
         payment of the taxes levied or assessed upon any part of the Pledged
         Property; or

                           (iii) (A) permit the validity or effectiveness of
         this Indenture to be impaired, or permit the lien in favor of the
         Indenture Trustee created by this Indenture to be amended,
         hypothecated, subordinated, terminated or discharged, or permit any
         Person to be released from any covenants or obligations with respect to
         the Notes under this Indenture except as may be expressly permitted
         hereby, (B) permit any lien, charge, excise, claim, security interest,
         mortgage or other encumbrance (other than the lien of this Indenture)
         to be created on or extend to or otherwise arise upon or burden the
         Pledged Property or any part thereof or any interest therein or the
         proceeds thereof (other than tax liens, mechanics' liens and other
         liens that arise by operation of law, in each case on Equipment and
         arising solely as a result of an action or omission of the related
         Obligor), or (C) permit the lien of this Indenture not to constitute a
         valid first priority (other than with respect to any such tax,
         mechanics' or other lien) security interest in the Pledged Property.

                              THE INDENTURE TRUSTEE

                  Section 7.01 Duties of Indenture Trustee. (a) The Indenture
Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture. If an Event of Default of which a
Responsible Officer of the Indenture Trustee shall have actual knowledge has
occurred and has not been cured or waived, the Indenture Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise as a prudent Person would exercise or
use under the circumstances in the conduct of such Person's own affairs.

                  (b) The Indenture Trustee, upon receipt of all resolutions,
certificates, statements, opinions, reports, documents, orders or other
instruments furnished to the Indenture Trustee that are specifically required to
be furnished pursuant to any provision of this Indenture, shall examine them to
determine whether they conform as to form to the requirements of this Indenture.
No acceptance of, or reliance on, any such item by the Indenture Trustee shall
constitute a representation by the Indenture Trustee of the enforceability or
sufficiency of such item.

                  (c) No provision of this Indenture shall be construed to
relieve the Indenture Trustee from liability for its own grossly negligent
action, its own grossly 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 curing of all such Events 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;

                                       29
<PAGE>   36

         the Indenture Trustee shall not be liable except for the performance
         of such duties and obligations as are specifically set forth in this
         Indenture; 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
         or opinions furnished to the Indenture Trustee and, if specifically
         required to be furnished pursuant to any provision of this Indenture,
         conforming to the requirements of this Indenture;

                           (ii) The Indenture Trustee shall not be liable for an
         error of judgment made in good faith by a Responsible Officer of the
         Indenture Trustee unless it shall be proved that the Indenture Trustee
         was grossly negligent in ascertaining the pertinent facts;

                           (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 this Indenture, pursuant
         to the direction of the Notes evidencing Percentage Interests in the
         related Class of not less than 25% of the Outstanding Amount of the
         related Class of Notes, relating to the time, method and place of
         conducting any proceeding for any remedy available to the Indenture
         Trustee, or exercising, suffering or omitting to take any trust or
         power conferred upon the Indenture Trustee, under this Indenture;

                           (iv) The Indenture Trustee shall not be charged with
         knowledge of any Event of Servicing Termination or any Event of Default
         unless a Responsible Officer of the Indenture Trustee obtains actual
         knowledge of such failure or event or the Indenture Trustee receives
         written notice of such failure or event from the Servicer, the Trust or
         any Noteholder; and

                           (v) The Indenture Trustee shall have no duty to
         monitor the performance of the Servicer (as custodian or otherwise),
         nor shall it have any liability in connection with the malfeasance or
         nonfeasance by the Servicer. The Indenture Trustee shall have no
         liability in connection with compliance of the Servicer or the Trust
         with statutory or regulatory requirements related to the Contracts or
         the related Equipment. The Indenture Trustee shall not make or be
         deemed to have made any representations or warranties with respect to
         the Contracts or related Equipment or the validity or sufficiency of
         any assignment of the Contracts to the Trust or the Indenture Trustee.
         The Indenture Trustee shall have no obligation or liability in respect
         of the maintenance of casualty or liability insurance in connection
         with the Contracts or the related Equipment.

                  (d) The Indenture Trustee shall not be required to expend or
risk its own funds or otherwise incur financial liability in the performance of
any of its duties hereunder, or in the exercise of any of its rights or powers,
if there is reasonable ground for believing that the repayment of such funds or
indemnity satisfactory to it against such risk or liability is not assured to
it, and none of the provisions contained in this Indenture shall in any event
require the Indenture Trustee to perform, or be responsible for the manner of
performance of, any of the obligations of the Servicer under this Indenture or
the Servicing Agreement except during such

                                       30
<PAGE>   37

time, if any, as the Indenture Trustee shall be the successor to, and be vested
with the rights, duties, powers and privileges of, the Servicer in accordance
with the terms of this Indenture.

                  (e) On each Determination Date, the Indenture Trustee shall
give notice, by facsimile, to a Servicing Officer of the Servicer if the total
amount then on deposit in the Collection Account in respect of the related
Collection Period is less than the amount indicated in the Monthly Statement.

                  Section 7.02 Eligible Investments. The Servicer shall direct
the Indenture Trustee to invest in Eligible Investments, as further specified
from time to time by written notice to the Indenture Trustee executed by a
Servicing Officer, any cash amounts deposited in the Collection Account pursuant
to the terms of this Indenture or the Servicing Agreement, immediately upon
deposit of any such cash amounts; provided, however, that each such Eligible
Investment (i) shall mature no later than the Business Day immediately preceding
the Payment Date in respect of the Collection Period during which such deposit
was made and (ii) shall not be sold or disposed of prior to its maturity. The
Indenture Trustee shall not be liable or responsible for the selection of or
losses on any investments made by it pursuant to and in compliance with such
instructions of the Servicer pursuant to this Section 7.02. The Indenture
Trustee shall have no obligation to initiate any investments in the absence of
such written direction.

                  Section 7.03 Indenture Trustee's Assignment of Contracts. If
in any enforcement suit or legal proceeding it is held, or in connection with
the collection of a Defaulted Contract the Servicer or its assigns reasonably
anticipates, that the Servicer or its assigns may not or will not be able to
enforce a Contract on the ground that neither the Servicer nor its assigns are a
real party in interest or a holder entitled to enforce the Contract, then the
Indenture Trustee shall, at the Servicer's or its assigns' expense, take such
steps as the Indenture Trustee deems necessary to enforce the Contract,
including (i) bringing suit in the Indenture Trustee's name or the names of the
Noteholders and (ii) executing and delivering all such instruments or documents
as shall be required to transfer title to a Contract to the Servicer or its
assigns or otherwise enforce such Contract.

                  Section 7.04 Certain Matters Affecting the Indenture Trustee.
Except as otherwise provided in Section 7.01:

                           (i) The Indenture Trustee may conclusively rely and
         shall be fully protected in acting or refraining from acting upon any
         resolution, Officer's Certificate, certificate of auditors or any other
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, appraisal, bond or other paper or document 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
         and any Opinion of Counsel or advice shall constitute 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 with such
         Opinion of Counsel or advice;

                           (iii) The Indenture Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by this
         Indenture, or to institute, conduct or defend any

                                       31
<PAGE>   38

         litigation hereunder or in relation hereto, at the request, order or
         direction of any of the Noteholders, pursuant to the provisions of this
         Indenture unless such Noteholders shall have offered to the Indenture
         Trustee such security or indemnity satisfactory to it against the
         costs, expenses, and liabilities that may be incurred therein or
         thereby that are reasonable in the opinion of the Indenture Trustee;
         provided, however, that nothing contained herein shall relieve the
         Indenture Trustee of the obligations, upon the occurrence of an Event
         of Default (that has not been cured), to exercise such of the rights
         and powers vested in it by this Indenture and to use the same degree of
         skill and care in their exercise as a prudent Person would exercise
         under the circumstances in the conduct of such Person's own affairs;

                           (iv) The Indenture Trustee shall not be personally
         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) Prior to the occurrence of an Event of Default of
         which a Responsible Officer of the Indenture Trustee shall have actual
         knowledge and after the curing of all Events of Default that may have
         occurred, 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 Holders of Notes of any Class
         evidencing Percentage Interests of not less than 25% of such Class;
         provided, however, that if the payment within a reasonable time to the
         Indenture Trustee of the costs, expenses or liabilities likely to be
         incurred by it in the making of such investigation is, in the opinion
         of the Indenture Trustee, not reasonably assured to the Indenture
         Trustee by the security afforded to it by the terms of this Indenture,
         the Indenture Trustee may require indemnity satisfactory to it against
         such cost, expense or liability as a condition to so proceeding. The
         reasonable expense of every such examination shall be paid by the
         requesting party or, if paid by the Indenture Trustee, shall be
         reimbursed by the Servicer upon demand. Nothing in this clause (v)
         shall derogate from the obligation of the Servicer to observe any
         applicable law prohibiting disclosure of information regarding the
         Obligors; and

                           (vi) The Indenture Trustee may execute any of the
         trusts or powers or perform any duties hereunder either directly or by
         or through agents or attorneys or a custodian. The Indenture Trustee
         shall not be responsible for the misconduct, negligence or for the
         supervision of any of the Indenture Trustee's agents or attorneys
         appointed with due care by the Indenture Trustee hereunder or that of
         SierraCities.com, the Servicer or the Trust.

                  Section 7.05 Indenture Trustee Not Liable for Notes or
Contracts. The Notes do not represent an obligation issued by the Indenture
Trustee or any Affiliate thereof. The promise to pay the Notes according to
their terms and the terms of this Indenture set forth in the Notes and in
Section 2.05 hereof provides recourse to the Pledged Property only. The
Indenture Trustee does not assume any responsibility for the accuracy of the
statements herein or in the Notes (other than as set forth in Section 7.17 and
the certificate of authentication on the Notes). The Indenture Trustee makes no
representations as to the validity or sufficiency of this Indenture

                                       32
<PAGE>   39

or of the Notes (other than the certificate of authentication on the Notes) or
of any Contract or related document. The Indenture Trustee shall at no time have
any responsibility or liability for or with respect to the legality, validity or
enforceability of any security interest in any Equipment or any Contract, to the
perfection or priority thereof, or to the efficacy of the Trust or any portion
thereof to pay any Note, the existence or validity of any Contract, the validity
of the assignment of any Contract or the related Pledged Property to the Trust
or of any intervening assignment, the review of any Contract, any Contract File
or the Computer Tape (it being understood that neither the Indenture Trustee nor
any of its agents have reviewed or intend to review such matters, the sole
responsibility for such review being vested in the Trust), the completeness of
any Contract File, the receipt by it or its custodian of any Contract, the
performance or enforcement of any Contract, subject to Section 4.01 of the
Servicing Agreement, the compliance by the Trust with any covenant or the breach
by SierraCities.com or the Trust of any warranty or representation made under
the Servicing Agreement, the Receivables Transfer Agreement or in any related
document or the accuracy of any such warranty or representation, any investment
of monies in the Collection Account (except to the extent that the Indenture
Trustee, in its individual capacity, is an obligor with respect to any such
investment) or any loss resulting therefrom, the acts or omissions of the
Servicer, or any Obligor, any action of the Servicer taken in the name of the
Indenture Trustee, any action by the Indenture Trustee taken at the instruction
of the Servicer or the preparation and filing of tax returns for the Trust. No
recourse shall be had for any claim based on any provision of this Indenture,
the Notes or any Contract or assignment thereof against Bankers Trust Company in
its individual capacity, and Bankers Trust Company shall not have any personal
obligation, liability or duty whatsoever to any Noteholder or any other Person
with respect to any such claim, and any such claim shall be asserted solely
against the Trust or any indemnitor who shall furnish indemnity as provided
herein, except for such liability as is determined to have resulted from its own
gross negligence or willful misconduct. The Indenture Trustee shall not be
accountable for the use or application by SierraCities.com or the Trust of any
of the Notes or of the proceeds of such Notes or for the use or application of
any funds paid to the Servicer in respect of the Contracts.

                  Section 7.06 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 as it would have if it were not Indenture Trustee,
subject to the definition of the term "Noteholder" in Annex A hereto.

                  Section 7.07 Indenture Trustee's Fees and Expenses. (a) The
Servicer on behalf of the Trust Certificate Holder agrees:

                           (i) to cause the Indenture Trustee to be paid
         pursuant to Section 3.05(b)(v), as applicable, on each Payment Date
         reasonable compensation for all services rendered by it hereunder
         (which compensation shall not be limited by any provision of law in
         regard to the compensation of a Indenture Trustee of an express trust);

                           (ii) except to the extent otherwise expressly
         provided herein, to cause the Indenture Trustee to be reimbursed
         pursuant to Section 3.05(b)(vi), as applicable, upon its request, for
         all reasonable expenses, disbursements and advances incurred or made by
         the Indenture Trustee in accordance with any provision of this
         Indenture (including

                                       33
<PAGE>   40

         the reasonable compensation and expenses and disbursements of any of
         its agents and counsel), except any such expense, disbursement or
         advance as may be attributable to its gross negligence or willful
         misconduct; provided, however, that for purposes of this clause (ii),
         such expenses, disbursements and advances shall be limited to an
         aggregate amount of $75,000; and

                           (iii) to cause the Indenture Trustee to be reimbursed
         pursuant to Section 3.05(b)(x), as applicable, for all reasonable
         expenses, disbursements and advances that would have been paid pursuant
         to Section 7.07(a)(ii) but for the $75,000 limitation.

                  (b) The Servicer's obligations under this Section 7.07 shall
survive the termination of this Indenture or the earlier resignation or removal
of the Indenture Trustee. The Indenture Trustee shall not be entitled to any
other or additional compensation or reimbursement, except as expressly provided
herein or as otherwise agreed from time to time.

                  (c) Subject to Section 7.10 hereof, the failure by the
Servicer to pay to the Indenture Trustee any compensation or other expenses
shall not relieve the Indenture Trustee of its obligations hereunder.

                  (d) In the event the Indenture Trustee performs services or
incurs expenses in the context of a proceeding described in Sections
6.01(a)(iv), 6.01(a)(v) or 6.01(a)(vii) of the Servicing Agreement, the fees for
such services and such expenses shall be considered expenses of administration
for the purposes of any bankruptcy laws or laws relating to creditors rights
generally.

                  Section 7.08 Eligibility Requirements for Indenture Trustee.
The Indenture Trustee shall at all times satisfy the requirements of TIA Section
310(a). The Indenture Trustee hereunder shall at all times be a corporation
having its principal office in a State, organized and doing business under the
laws of any State or the United States of America, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000 and subject to supervision or examination by federal or State
authority; provided, however, that no entity shall qualify as Indenture Trustee
hereunder to the extent that such qualification would, in itself, affect any
then current rating of the Notes by the Rating Agencies. If such corporation
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the
purpose of this Section 7.08, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. Any successor Indenture
Trustee's deposit ratings shall be at least "investment grade" by the Rating
Agencies. In case at any time the Indenture Trustee shall cease to be eligible
in accordance with the provisions of this Section 7.08, the Indenture Trustee
shall resign immediately in the manner and with the effect specified in Section
7.10 hereof. The Indenture Trustee shall comply with TIA Section 310(b),
including the optional provision permitted by the second sentence of TIA Section
310(b)(9); provided, however, that there shall be excluded from the operation of
TIA Section 310(b)(1) any indenture or indentures under which other securities
of the Trust are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

                                       34
<PAGE>   41

                  Section 7.09 Preferential Collection of Claims Against Issuer.
The Indenture Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). An Indenture Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated.

                  Section 7.10 Resignation or Removal of 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 Servicer, the Trust and
each Noteholder, which resignation will not become effective until such time as
a successor Indenture Trustee has been appointed in accordance with the
provisions of this Section 7.10. Upon receiving such notice of resignation, the
Servicer shall promptly appoint a successor Indenture Trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
resigning Indenture Trustee and one copy to the successor Indenture Trustee. If
no successor Indenture Trustee shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Indenture Trustee may petition any court of competent jurisdiction for
the appointment of a successor Indenture Trustee.

                  (a) If at any time the Indenture Trustee shall cease to be
eligible in accordance with the provisions of Section 7.08 hereof and shall fail
to resign after written request therefor by the Servicer, or the Holders of
Notes of any Class evidencing Percentage Interests of more than 25% of such
Class, or, if at any time the Indenture Trustee shall be legally unable to act,
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 Servicer
shall, at the direction of the Holders of Notes of any Class evidencing
Percentage Interests of more than 25% of the related Class remove the Indenture
Trustee. If the Servicer or Noteholders remove the Indenture Trustee, the
Servicer or such Noteholders shall promptly appoint a successor Indenture
Trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the Indenture Trustee so removed and one copy to the successor
Indenture Trustee.

                  (b) Any resignation or removal of the Indenture Trustee and
appointment of a successor Indenture Trustee pursuant to this Section 7.10 shall
not become effective until acceptance of appointment by the successor Indenture
Trustee as provided in Section 7.11 hereof. Notice of the resignation or removal
of the Indenture Trustee shall be given in writing to the Rating Agencies by the
Servicer. In the event no successor Indenture Trustee has been appointed within
30 days of the resignation or removal of the Indenture Trustee, the Indenture
Trustee or the Majority Holders of the Notes may petition a court of competent
jurisdiction to appoint a successor Indenture Trustee.

                  Section 7.11 Successor Indenture Trustee. (a) Any successor
Indenture Trustee appointed as provided in Section 7.10 hereof shall execute,
acknowledge and deliver to the Servicer, the Trust and the 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 Indenture Trustee. The

                                       35
<PAGE>   42

predecessor Indenture Trustee shall deliver to the successor Indenture Trustee
all documents and statements held by it hereunder. The Servicer, the Trust and
the predecessor Indenture Trustee shall execute and deliver such instruments and
do such other things as may reasonably be required for fully and certainly
vesting and confirming in the successor Indenture Trustee all such rights,
powers, duties and obligations. The predecessor Indenture Trustee shall not be
liable for the acts or omissions of any successor Indenture Trustee hereunder.

                  (b) No successor Indenture Trustee shall accept appointment as
provided in this Section 7.11 unless at the time of such acceptance such
successor Indenture Trustee shall be eligible as the Indenture Trustee under the
provisions of Section 7.08 hereof, and as a successor Servicer under the
provisions of Section 6.02 of the Servicing Agreement.

                  (c) Upon acceptance of appointment by a successor Indenture
Trustee as provided in this Section 7.11, the Servicer shall mail notice of the
succession of such Indenture Trustee hereunder to all Noteholders at their
addresses as shown in the Note Register. If the Servicer fails to mail such
notice within 10 days after acceptance of appointment by such successor
Indenture Trustee, then the successor Indenture Trustee shall cause such notice
to be mailed at the expense of the Servicer.

                  Section 7.12 Merger or Consolidation of Indenture Trustee. Any
corporation into which the Indenture Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion, or consolidation to which the Indenture Trustee shall be a party, or
any corporation succeeding to the corporate trust business of the Indenture
Trustee, shall be the successor of the Indenture Trustee hereunder, provided
such corporation shall be eligible under the provisions of Section 7.08 hereof,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

                  Section 7.13 Appointment of Co-Indenture Trustee or Separate
Indenture Trustee. (a) Notwithstanding any other provisions of this Indenture,
at any time, for the purpose of meeting any legal requirements of any
jurisdiction in which any part of the Trust or any Equipment may at the time be
located, the Indenture Trustee shall execute and deliver all instruments to
appoint one or more Persons approved by the Indenture Trustee to act as
co-Indenture Trustee or co-Indenture Trustees, jointly with the Indenture
Trustee, or separate Indenture Trustee or separate Indenture Trustees, of all or
any part of the Trust, and to vest in such Person or Persons, in such capacity
and for the benefit of the Noteholders, such title to the Trust, or any part
thereof, and, subject to the other provisions of this Section 7.13, such powers,
duties, obligations, rights and trusts as the Servicer, the Trust and the
Indenture Trustee may consider necessary or desirable. If the Servicer shall not
have joined in such appointment within 15 days after the receipt by it of a
request so to do, or in the case an Event of Servicing Termination shall have
occurred and be continuing, the Indenture Trustee alone shall have the power to
make such appointment; provided, however, that if the Trust shall not have
joined in such appointment within 15 days after the receipt by it of a request
so to do, the Indenture Trustee alone shall have the power to make such
appointment. No co-Indenture Trustee or separate Indenture Trustee hereunder
shall be required to meet the terms of eligibility as a successor Indenture
Trustee under Section 7.08 hereof, and no notice to Noteholders of the
appointment of any co-Indenture Trustee or separate Indenture Trustee shall be
required under Section 7.12 hereof.

                                       36
<PAGE>   43

                  (b) Every separate Indenture Trustee and co-Indenture Trustee
shall, to the extent permitted by law, be appointed and act subject to the
following provisions and conditions:

                           (i) All 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 Indenture Trustee or co-Indenture Trustee jointly (it
         being understood that such separate Indenture Trustee or co-Indenture
         Trustee is not authorized to act separately without the Indenture
         Trustee joining in such act), except to the extent that under any law
         of any jurisdiction in which any particular act or acts are to be
         performed (whether as Indenture Trustee hereunder or as successor to
         the Servicer hereunder), the Indenture Trustee shall be incompetent or
         unqualified to perform such act or acts, in which event such rights,
         powers, duties and obligations (including the holding of title to the
         Pledged Property or any portion thereof in any such jurisdiction) shall
         be exercised and performed singly by such separate Indenture Trustee or
         co-Indenture Trustee but solely at the direction of the Indenture
         Trustee;

                           (ii) No separate Indenture Trustee or co-Indenture
         Trustee hereunder shall be personally liable by reason of any act or
         omission of any other separate Indenture Trustee or co-Indenture
         Trustee hereunder; and

                           (iii) The Indenture Trustee may at any time accept
         the resignation of or remove any separate Indenture Trustee or
         co-Indenture Trustee.

                  (c) Any notice, request or other writing given to the
Indenture Trustee shall be deemed to have been given to each of the then
separate Indenture Trustees and co-Indenture Trustees, as effectively as if
given to each of them. Every instrument appointing any separate Indenture
Trustee or co-Indenture Trustee shall refer to this Indenture and the conditions
of this Article VII. Each separate Indenture Trustee and co-Indenture 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 shall be filed with
the Indenture Trustee and a copy thereof given to the Servicer and the Trust.

                  (d) Any separate Indenture Trustee or co-Indenture Trustee 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 Indenture Trustee or co-Indenture Trustee shall die, become
incapable of acting, resign or be removed, then 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 separate Indenture Trustee or successor co-Indenture Trustee.

                                       37
<PAGE>   44

                  (e) The Servicer shall be responsible for the payment of any
fees or expenses of any separate Indenture Trustee or co-Indenture Trustee.

                  Section 7.14 Indenture Trustee May Enforce Claims Without
Possession of Note. All rights of action and claims under this Indenture or the
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 or in its capacity as Indenture Trustee. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Indenture Trustee, its
agents and counsel, be for the ratable benefit of the Noteholders in respect of
which such judgment has been recovered.

                  Section 7.15 Suits for Enforcement. In case an Event of
Servicing Termination or other default by the Servicer under the Servicing
Agreement or under this Indenture shall occur and be continuing, the Indenture
Trustee, in its discretion, may, subject to the provisions of 6.04 of the
Servicing Agreement, proceed to protect and enforce its rights and the rights of
the Noteholders under this Indenture by a suit, action or proceeding in equity
or at law or otherwise, whether for the specific performance of any covenant or
agreement contained in this Indenture or in aid of the execution of any power
granted in this Indenture or for the enforcement of any other legal, equitable
or other remedy, as the Indenture Trustee, being advised by counsel, shall deem
most effectual to protect and enforce any of the rights of the Indenture Trustee
and the Noteholders.

                  Section 7.16 Undertaking for Costs. All parties to this
Indenture agree (and each holder of any Note by its 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
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,
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; but the
provisions of this Section shall not apply to any suit instituted by the
Indenture Trustee, to any suit instituted by any Noteholder, or group of
Noteholders, holding in the aggregate more than 10% of the then outstanding
principal balance of the Notes, or to any suit instituted by any Noteholder for
the enforcement of the payment of the principal of or interest on any Note on or
after the maturities for such payments, including the stated maturity as
applicable.

                  Section 7.17 Representations and Warranties of Indenture
Trustee. The Indenture Trustee represents and warrants for the benefit of the
Noteholders that:

                  (a) Organization and Good Standing. The Indenture Trustee is a
banking corporation duly organized, validly existing and in good standing under
the laws of the state of New York.

                  (b) Authorization. The Indenture Trustee has the power,
authority and legal right to execute, deliver and perform this Indenture, and
the execution, delivery and performance

                                       38
<PAGE>   45

of this Indenture have been duly authorized by the Indenture Trustee by all
necessary corporate action.

                  (c) Binding Obligations. This Indenture, assuming due
authorization, execution and delivery by all other parties thereto, constitutes
the legal, valid and binding obligation of the Indenture Trustee, enforceable
against the Indenture Trustee in accordance with its terms, except that (i) such
enforcement may be subject to bankruptcy, insolvency, reorganization, moratorium
or other similar laws (whether statutory, regulatory or decisional) now or
hereafter in effect relating to creditors' rights generally and the rights of
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
proceeding therefor may be brought, whether in a proceeding at law or in equity.

                  Section 7.18 Tax Returns. In the event the Trust shall be
required to file tax returns, the Servicer shall prepare or shall cause to be
prepared any tax returns required to be filed by the Trust and shall remit such
returns to the Owner Trustee for signature at least five days before such
returns are due to be filed. The Indenture Trustee, upon request, will furnish
the Servicer with all such information known to the Indenture Trustee as may be
reasonably required in connection with the preparation of all tax returns of the
Trust. In no event shall the Indenture Trustee or the Owner Trustee in their
respective individual capacities be liable for any liabilities, costs or
expenses of the Trust, the Noteholders or the Servicer arising under any tax law
or regulation, including, without limitation, federal, state or local income or
excise taxes or any other tax imposed on or measured by income (or any interest
or penalty with respect thereto or arising from any failure to comply
therewith).

                                  ARTICLE VIII.

                           EVENTS OF DEFAULT; REMEDIES

                  Section 8.01 Events of Default. "Event of Default" wherever
used herein means any one of the following events (whatever the reason for such
Event of Default and without regard to whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

                  (a) failure to distribute or cause to be distributed to the
Indenture Trustee, for the benefit of the Noteholders, all or part of any
payment of interest required to be made under the terms of such Notes or this
Indenture on each Payment Date when such amount is due and payable;

                  (b) failure to distribute or cause to be distributed to the
Indenture Trustee, for the benefit of the Noteholders (x) on any Payment Date,
an amount equal to the principal due on the Outstanding Notes as of such Payment
Date to the extent that sufficient Available Funds are on deposit in the
Collection Account or (y) on the Class A-1 Maturity Date, the Class A-2

                                       39
<PAGE>   46

Maturity Date, or the Class B Maturity Date, as the case may be, any remaining
principal owed on the Outstanding Class A-1 Notes, Class A-2 Notes, or Class B
Notes, as the case may be;

                  (c) any failure on the part of the Trust duly to observe or
perform in any material respect any other covenants or agreements of the Trust
set forth in the Notes, in this Agreement or in any of the Transaction
Documents, as the case may be, or any breach of a representation or warranty of
the Trust set forth in the Transaction Documents, which failure or breach (A)

                  Section 8.02 Acceleration of Maturity, Rescission and
Annulment. (a) If an Event of Default occurs and is continuing, then and in
every such case the Indenture Trustee, at the written direction of the Majority
Holders, shall declare the principal of all of the Notes to be immediately due
and payable, by a notice in writing to the Servicer, and upon any such
declaration such principal (together with all accrued and previously unpaid
interest) shall become immediately due and payable. The Indenture Trustee shall
give notice to each Noteholder and the Rating Agencies of such declaration.

                  (b) At any time, after such a declaration of acceleration has
been made, but before any sale of the Pledged Property has been made or a
judgment or decree for payment of the money due has been obtained by the
Indenture Trustee as hereinafter in this Article VIII provided, the Majority
Holders, by written notice to the Servicer and the Indenture Trustee, may
rescind and annul such declaration and its consequence if monies have been paid
or deposited with the Indenture Trustee in a sum sufficient to pay:

                           (i) all overdue installments of interest on all Class
         A Notes and the Class B Notes;

                           (ii) the principal of any of the Class A Notes or the
         Class B Notes which has become due otherwise than by such declaration
         of acceleration and interest thereon at the applicable Note Rate;

                           (iii) to the extent that payment of such interest is
         lawful, interest upon overdue installments of interest on the Class A
         Notes and the Class B Notes at the rate specified therefor in the
         applicable Notes; and

                           (iv) all sums paid or advanced, together with
         interest thereon, by the Indenture Trustee hereunder and the reasonable
         compensation, expenses, disbursements and advances of the Indenture
         Trustee and its agents and counsel.

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

Subsequent to any such declaration of acceleration and so long as such
declaration and its consequences have not been rescinded and annulled, prior to
the exercise by the Indenture Trustee of the remedies set forth in Section
8.03(b) or (c) hereof, the Indenture Trustee shall give the Noteholders ten days
notice of its intention to take such actions.

                  Section 8.03 Remedies. If an Event of Default shall have
occurred and be continuing, the Indenture Trustee, at the written direction of
the Majority Holders, may do one or more of the following:

                           (i) institute, in its own name and as Indenture
         Trustee, Proceedings for the collection of the entire amount of
         principal and interest remaining unpaid on the Notes, or under this
         Indenture in respect of the Notes, whether by declaration or otherwise,
         enforce any judgment obtained, and collect from the Pledged Property
         securing the Notes the monies adjudged due;

                                       41
<PAGE>   48

                           (ii) sell the Pledged Property or any portion thereof
         or rights or interest therein, at one or more sales called and
         conducted in any manner permitted by law;

                           (iii) institute Proceedings from time to time for the
         complete or partial foreclosure of this Indenture with respect to the
         Pledged Property securing the Notes; or

                           (iv) exercise any remedies of a secured party under
         the UCC or other applicable law and take any other appropriate action
         to protect and enforce the rights and remedies of the Indenture Trustee
         or the Noteholders hereunder.

                  Section 8.04 Notice of Event of Default. Within two Business
Days after a Responsible Officer obtaining actual knowledge of the occurrence of
any Event of Default, the Indenture Trustee shall transmit, by certified mail
return receipt requested, hand delivery or overnight courier, to all
Noteholders, as their names and addresses appear in the Register, notice of such
Event of Default, unless such Event of Default shall have been cured or waived.

                  Section 8.05 Exercise of Power by Indenture Trustee. In case
an Event of Default has occurred and is continuing to the actual knowledge of a
Responsible Officer of the Indenture Trustee, the Indenture Trustee shall
exercise such of the rights and powers vested in it by this Indenture, 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 his own affairs.

                  Section 8.06 Indenture Trustee May File Proofs of Claim. In
case of the pendency of any receivership, insolvency, liquidation,
reorganization, arrangement, adjustment, composition or other judicial
Proceeding, relating to the Trust or any other obligor upon the Notes or the
property of the Trust or of such other obligor or their creditors, the Indenture
Trustee (irrespective of whether the principal of any class of Notes shall then
be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Indenture Trustee shall have made any demand for the
payment of overdue principal or interest) shall be entitled and empowered, to
intervene in such proceeding or otherwise:

                  (a) to file and prove a claim for all amounts owing and unpaid
in respect of the Notes and to file such other papers or documents and take such
other action including participating as a member, voting or otherwise, in any
committee of creditors appointed in the matter, as may be necessary or advisable
in order to have the claims of the Indenture Trustee (including, in each case,
any claim for the reasonable compensation, expenses, disbursements and advances
of the Indenture Trustee and its agents and counsel) and the Noteholders allowed
in such judicial Proceeding;

                  (b) to petition for lifting of the automatic stay and
thereupon to foreclose upon the Pledged Property as elsewhere provided herein;
and

                  (c) to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, liquidator, or sequestrator (or other
similar official) in any such judicial Proceeding is hereby authorized by each
Noteholder to make such payments to the Indenture Trustee, and in the event that
the Indenture Trustee shall consent to the making of such

                                       42
<PAGE>   49

payments directly to the Noteholders, to pay to the Indenture Trustee any amount
due to it for the reasonable compensation, expenses, disbursements and advances
of the Indenture Trustee, its agents and counsel.

Nothing herein contained shall be deemed to authorize the Indenture Trustee to
authorize or to consent or accept or adopt on behalf of any Noteholder any plan
of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Indenture Trustee to vote
in respect of the claim of any Noteholder in any such Proceeding.

                  Section 8.07 Allocation of Money Collected. Any money
collected by the Indenture Trustee with respect to the Notes pursuant to the
remedies set forth in Section 8.03 (and any funds then held or thereafter
received by the Indenture Trustee) shall be applied in the following order, at
the date or dates fixed by the Indenture Trustee; provided, however, that the
provisions of this Section 8.07 shall not preclude the Indenture Trustee from
receiving indemnities satisfactory to it from the Noteholders against the costs,
expenses and liabilities it may incur in acting in compliance with the written
directions of any Noteholder or Noteholders:

                               First: To the payment of all amounts due the

                               Sixth: To the payment of all reasonable costs and

rights hereunder or under the Notes, ratably, without preference or priority of
any kind; and

the written direction of the Trust Certificate Holder.

                  Section 8.08 Waiver of Events of Default. (a) The holders of
66-2/3% of the Outstanding Amount of the Notes may, by one or more instruments
in writing, waive any Event of Default hereunder and its consequences, except a
continuing Event of Default:

                           (i) in respect of the payment of the principal of or
         interest on any Note (which may only be waived by the Holder of such
         Note), or

                           (ii) in respect of a covenant or provision hereof
         which under Article XI cannot be modified or amended without the
         consent of the Holder of each Note outstanding affected (which only may
         be waived by the Holders of all Notes outstanding affected).

                                       43
<PAGE>   50

         (b) A copy of each waiver pursuant to Section 8.08(a) shall be
furnished by the Servicer to the Indenture Trustee. Upon any such waiver, such
Event of Default shall cease to exist and shall be deemed to have been cured,
for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Event of Default or impair any right consequent thereon.

         Section 8.09 Limitation On Suits. No Holder shall have any right to
institute any Proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

         (a) such Holder has previously given written notice to the Indenture
Trustee of a continuing Event of Default;

Indenture Trustee to institute Proceedings in respect of such Event of Default
in its own name as Indenture Trustee hereunder;

indemnity reasonably satisfactory to it against the costs, expenses and
liabilities to be incurred in compliance with such request;

         (d) the Indenture Trustee for 30 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such Proceeding; and

         (e) no direction inconsistent with such written request has been given
to the Indenture Trustee during such 30 day period by the Majority Holders;

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

         Section 8.10 Unconditional Right of Noteholders to Receive Principal
and Interest. Notwithstanding any other provision in this Indenture, the

receive payment of the principal of and interest on such Note as such principal
and interest becomes due and payable in accordance with the terms of this
Indenture (including, without limitation, the limitation on such payments to the
extent of Available Funds on each Payment Date) and to institute suit for the

Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy in accordance with the terms of this Indenture and such Proceeding has

Indenture Trustee and the Noteholders shall, subject to any determination

conferred upon or reserved to the Indenture Trustee or the Noteholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

         Section 8.13 Delay or Omission Not Waiver. No delay or omission of the
Indenture Trustee or any Noteholder 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 the
Noteholders, or any of them, may be exercised from time to time, as often as may
be deemed expedient, by the Indenture Trustee or the Noteholders.

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

         (b) the Indenture Trustee may take any other action deemed proper by
the Indenture Trustee which is not inconsistent with such direction; provided,
however, that the Indenture Trustee need not take any action which it determines
might involve it in liability or be unjustly prejudicial to the Holders not
consenting.

         Section 8.15 Sale of Pledged Property. (a) The power to effect any sale
pursuant to Section 8.03 hereof shall not be exhausted by any one or more sales
as to any portion of the Pledged Property remaining unsold, but shall continue

been paid. The Indenture Trustee may from time to time postpone any sale by
public announcement made at the time and place of such sale.

         (b) Any Noteholder may bid for and acquire any portion of the Pledged
Property securing the Notes in connection with any sale thereof.

inquire into the satisfaction of any conditions precedent or see to the
application of any monies.

recover judgment on the Notes or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Noteholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Trust or the Depositor or by
the levy of any execution under such judgment upon any portion of the Pledged
Property or upon any of the assets of the Trust or the Depositor.

                                   ARTICLE IX.

unclaimed, the Servicer shall, at its expense, cause to be published once, in
the eastern edition of The Wall Street Journal, notice that such money remains
unclaimed. If, within two years after such publication, such amount remains
unclaimed, the Servicer shall be entitled to all unclaimed funds and other
assets which remain subject hereto, and the Indenture Trustee upon written
direction from the Servicer shall transfer such funds and shall be discharged of
any responsibility for such funds and, the Noteholders shall look to the
Servicer for payment.

         representations and warranties made in the Servicing Agreement and
         each Seller shall have performed all obligations to be performed by it
         hereunder on or prior to such Subsequent Transfer Date;

                  (iv) The Sellers shall not have selected such Subsequent
         Contracts in a manner that they reasonably believe is adverse to the
         interests of the Noteholders;

                  (v) Such sale and transfer shall not result in a material
         adverse tax consequence to the Trust;

                  (vi) The Pre-Funding Period shall not have terminated;

                  (vii) The Sellers shall have provided the Indenture Trustee

         transfer of such Subsequent Contracts.

the sale, assignment, transfer and conveyance of the Contracts to the Trust
pursuant to this Agreement, the Indenture Trustee will retain the Contract
Files and any related evidence of insurance and payments in accordance with the
terms of the Indenture.

                  SECTION 2.04 Intention of the Parties; Grant of Security
Interest. It is the intention of the parties hereto that each transfer of the
Conveyed Assets to be made pursuant to the terms hereof shall constitute an
absolute assignment and a sale of such Contract by each Seller to the Trust and
not a loan. In the event, however, that a court of competent jurisdiction were
to hold that any such transfer constitutes a loan and not a sale, it is the
intention of the parties hereto that this Agreement and each Subsequent
Transfer Agreement is deemed to be a security agreement and that each Seller
shall be deemed to have granted to the Trust as of the related Conveyance Date
a first priority perfected security interest in all of such Seller's right,
title and interest in, to and under each Conveyed Asset, and all income and
proceeds thereof. Such grant is made to secure the payment of all amounts
payable under this Agreement and each related Subsequent Transfer Agreement.

                  (x) No Proceedings. There are no proceedings or
         investigations pending, or, to the knowledge of VFCC, threatened,
         before any court, regulatory body, administrative agency, or other
         tribunal or Governmental Authority (A) asserting the invalidity of
         this Agreement, (B) seeking to prevent the consummation of any of the
         transactions contemplated by this Agreement, or

                                      17
<PAGE>   21

         (C) seeking any determination or ruling that might (in the reasonable
         judgment of VFCC) materially and adversely affect the performance by
         VFCC of its obligations under, or the validity or enforceability of,
         this Agreement;

                  (xi) No Consent Required. VFCC is not required to obtain the
         consent of any other Person, or any consent, license, approval or
         authorization or registration or declaration with, any governmental
         authority, bureau or agency in connection with the execution, delivery
         or performance of this Agreement and the other Transaction Documents
         to which it is a party except for such having been obtained, effected
         or made;

                  (xii) Fair Consideration. The consideration received by VFCC
         as set forth herein is fair consideration having value reasonably
         equivalent to or in excess of the value of the Conveyed Assets
         conveyed by it and the performance of VFCC's obligations hereunder;
         and

                  (xiii) Accounting Treatment. VFCC will treat the assignment
         of the Conveyed Assets to the Trust pursuant to Article II as a sale
         of the Conveyed Assets to the Trust for financial reporting and
         accounting purposes.

                  (e) FFC hereby makes the following representations and
warranties for the benefit of the Indenture Trustee, the Noteholders and the
Trust. Such representations and warranties are made as of each Conveyance Date
and shall survive each sale, assignment, transfer and conveyance by the Sellers
of the respective Conveyed Assets to the Trust and its successors and assigns:

                  (i) Organization and Good Standing. FFC is a corporation duly
         organized, validly existing and in good standing, under the laws of
         the State of Delaware, with corporate power and authority to own its
         properties and to conduct its business as such properties are
         currently owned and such business is currently conducted, and had at
         all relevant times, and now has, power, authority, and legal right to
         acquire and own the Conveyed Assets;

                  (ii) Due Qualification. FFC is qualified as a foreign
         corporation in any state where it is required to be so qualified to
         conduct its business and has obtained all necessary licenses, consents
         and approvals as required under federal and state law, in each case,
         where the failure to be so qualified, licensed, consented to or
         approved could reasonably be expected materially and adversely to
         affect the ability of FFC to comply with the terms of this Agreement
         or each Transaction Document to which it is a party;

                  (iii) Power and Authority. FFC has the corporate power and
         authority to execute and deliver this Agreement and any other
         Transaction Document to which it is a party, and to carry out their
         respective terms; and the execution, delivery, and performance of this
         Agreement and each Transaction Document to which it is a party has
         been duly authorized by FFC by all necessary corporate action;

                                      18
<PAGE>   22

                  (iv) Due Execution and Delivery. This Agreement has been duly
         executed and delivered on behalf of FFC;

                  (v) Valid Assignment; Binding Obligations. This Agreement
         constitute a valid sale, assignment, transfer and conveyance to the
         Owner Trustee, on behalf of the Trust, of all right, title, and
         interest of FFC in, to and under the Conveyed Assets and the Conveyed
         Assets will be held by the Trust free and clear of any Lien of any
         Person claiming, through or under FFC, except the lien on the Conveyed
         Assets in favor of the Indenture Trustee granted pursuant to the
         Indenture; and this Agreement, when duly executed and delivered, will
         constitute the legal, valid, and binding obligation of FFC enforceable
         against FFC in accordance with their respective terms subject as to
         enforceability to applicable bankruptcy, reorganization, insolvency,
         moratorium or other laws affecting creditors' rights generally and to
         general principles of equity (regardless of whether enforcement is
         sought in a proceeding in equity or at law);

                  (vi) No Violation. The consummation of the transactions
         contemplated by and the fulfillment of the terms of this Agreement
         will not conflict with, result in any breach of any of the terms and
         provisions of, or constitute (with or without notice or lapse of time)
         a default under, the articles of incorporation or bylaws of FFC, or
         any material term of any indenture, agreement, mortgage, deed of
         trust, or other instrument to which FFC is a party or by which it is
         bound, or result in the creation or imposition of any Lien upon any of
         its properties pursuant to the terms of any such indenture, agreement,
         mortgage, deed of trust, or other instrument, other than this
         Agreement, or violate any law or any order, injunction, writ, rule, or
         regulation applicable to FFC of any court or of any federal or state
         regulatory body, administrative agency, or other Governmental
         Authority having jurisdiction over FFC or any of its properties which
         would have a material adverse effect on the Conveyed Assets;

                  (vii) Valid Business Reasons. FFC has valid business reasons
         for selling its interest in the Conveyed Assets rather than obtaining
         a loan with the Conveyed Assets as collateral;

                  (viii) Absence of Event. No event has occurred which
         adversely affects FFC's operations or its ability to perform its
         obligations under the Transaction Documents to which it is a party;

                  (ix) Insolvency. FFC is not insolvent and will not be
         rendered insolvent by the transactions contemplated by this Agreement
         and has an adequate amount of capital to conduct its business in the
         ordinary course and to carry out its obligations hereunder and under
         each other Transaction Document to which it is a party;

                  (x) No Proceedings. There are no proceedings or
         investigations pending, or, to the knowledge of FFC, threatened,
         before any court, regulatory body, administrative agency, or other
         tribunal or Governmental Authority

         (A) asserting the invalidity of this Agreement, (B) seeking to prevent
         the consummation of any of the transactions contemplated by this
         Agreement, or (C) seeking any determination or ruling that might (in
         the reasonable judgment of FFC) materially and adversely affect the
         performance by FFC of its obligations under, or the validity or
         enforceability of, this Agreement;

                  (xi) No Consent Required. FFC is not required to obtain the
         consent of any other Person, or any consent, license, approval or
         authorization or registration or declaration with, any governmental
         authority, bureau or agency in connection with the execution, delivery
         or performance of this Agreement and the Transaction Documents to
         which it is a party except for such having been obtained, effected or
         made;

                  (xii) Fair Consideration. The consideration received by FFC
         as set forth herein is fair consideration having value reasonably
         equivalent to or in excess of the value of the Conveyed Assets
         conveyed by it and the performance of FFC's obligations hereunder; and

                  (xiii) Accounting Treatment. FFC will treat the assignment of
         the Conveyed Assets to the Trust pursuant to Article II as a sale of
         the Conveyed Assets to the Trust for financial reporting and
         accounting purposes.

                  SECTION 3.02 Removal of Non-Conforming Contracts by

Indenture.

                  (b) Any substitution of a Contract pursuant to this Agreement
will be effected by (i) delivery to the Indenture Trustee, as custodian of the

necessary to perfect the interest of the Trust and the Indenture Trustee in the
Substitute Contracts, (iii) delivery to the Indenture Trustee of a List of
Substitute Contracts reflecting such substitution and (iv) delivery to the

                  (c) The parties hereto agree that in addition to the
obligation of SierraCities.com to repurchase or to substitute any Contract and
the related Equipment as to which a breach of the representations set forth in
the Servicing Agreement has occurred and is continuing, SierraCities.com will
enforce its remedies against the Source under the Source Agreement. In
consideration of the purchase of the Equipment and the Contract,
SierraCities.com shall remit the Repurchase Amount to the Servicer for
allocation of such Repurchase Amount pursuant to the terms of the Indenture.
Except as may be set forth in the Transaction Documents, it is understood and
agreed that the obligations of SierraCities.com with respect to a breach as
provided in this Section 3.03 and Section 4.01 of the Indenture constitute the
sole remedy against SierraCities.com for such breach available to the Trust,
the Indenture Trustee and Noteholders. The representations and warranties set
forth in Sections 3.01 and 3.02 hereof shall survive the assignment of the
Conveyed Assets to the Owner Trustee, on behalf of the Trust, and the pledge of
the Pledged Property to the Indenture Trustee.

                  (d) Except as provided in this Article III, upon each
Seller's transfer of its interest in the Conveyed Assets to the Trust, the
Sellers will not bear any further risk with respect to the ultimate
collectibility of the Contracts or the adequacy of the collateral securing the
Contracts or the value or sufficiency of the Equipment.

                                  ARTICLE IV

                                   COVENANTS

the Trust, the Noteholders and the Indenture Trustee with respect to itself as
follows:

                  (a) Preservation of Security Interest. The Sellers shall
execute and file such financing statements and cause to be executed and filed
such continuation statements, all in such manner and in such places as may be
required by the Filing Requirements and by law fully to preserve, maintain, and
protect the respective right, title and interest of the Owner Trustee, on
behalf of the Trust, and the Indenture Trustee in the Conveyed Assets.
SierraCities.com shall deliver (or cause to be delivered) to the Trust
file-stamped copies of, or filing receipts for, any document filed as provided

Sellers and SierraCities.com will duly fulfill all obligations on its part to
be fulfilled under or in connection with each Contract and the Source
Agreement, and will do nothing to impair the rights of the Owner Trustee, on

material respects, with all acts, rules, requisitions, orders, decrees and
directions of any Governmental Authority applicable to its business and to the

may contest any act, regulation, order, decree or direction in any reasonable
manner which shall not materially and adversely affect the rights of the Trust,
the Indenture Trustee or the Owner Trustee in the Conveyed Assets.

                  (d) Conveyance of Conveyed Assets; Security Interests. Except

right, title, and interest of the Owner Trustee, on behalf of the Trust, the
Indenture Trustee and their respective successors and assigns in, to, and under
the Conveyed Assets, against all claims of third parties claiming, through or
under the Sellers; provided, however, that nothing in this Section 4.01(d)
shall prevent or be deemed to prohibit SierraCities.com from suffering to exist
upon any of the Conveyed Assets any Liens for municipal or other local taxes if
such taxes shall not at the time be due and payable or if SierraCities.com
shall concurrently be contesting the validity thereof in good faith by
appropriate proceedings and shall have set aside on its books adequate reserves
with respect thereto and such contests pose no risk of forfeiture.

                  (e) Notification of Breach. The Sellers will advise the Trust
and the Indenture Trustee promptly, in reasonable detail, upon discovery of the
occurrence of any breach by SierraCities.com of any of its representations,
warranties and covenants contained herein.

         reports and other assurances or instruments and take such further
         steps relating to the Conveyed Assets and other rights covered by this
         Agreement, as the Trust or the Indenture Trustee may request and
         reasonably require, provided that no UCC filing will be required with
         respect to the Equipment, except as required by the Filing
         Requirements.

                  (ii) The Sellers hereby agree to do all acts, transactions,
         and things and to execute and deliver all agreements, documents,
         instruments, and papers by and on behalf of the Sellers as the Trust
         or its counsel may reasonably request in order to consummate the
         transfer of the Conveyed Assets to the Trust and the subsequent pledge
         thereof to the Indenture Trustee for the benefit of the Noteholders,
         and the rating, issuance and sale of the Notes.

insofar as such loss, liability, damage, judgment, claim, deficiency, or
expense arises out of or is based upon a breach by SierraCities.com of its
representations and warranties contained in Section 3.01 or its covenants
contained in Section 4.01, or any information certified or set forth in this
Agreement or in any schedule delivered by SierraCities.com hereunder, being
untrue in any material respect at any time. The obligations of SierraCities.com
under this Section 4.01(g) shall be considered to have been relied upon by the
Trust, the Owner Trustee and the Indenture Trustee and shall survive the
execution, delivery, and performance of this Agreement regardless of any
investigation made by the Trust, the Owner Trustee, the Indenture Trustee or on
their respective behalf. THE INDEMNIFICATION OBLIGATIONS OF SIERRACITIES.COM
PURSUANT TO THE PRECEDING PROVISIONS OF THIS PARAGRAPH SHALL APPLY REGARDLESS
OF ANY NEGLIGENCE OR OTHER FAULT ON THE PART OF THE TRUST, THE OWNER TRUSTEE,
THE INDENTURE TRUSTEE OR ANY OF THEIR RESPECTIVE OFFICERS, EMPLOYEES OR AGENTS.

taxes required to be paid in connection with the assignment of the Conveyed
Assets and acknowledges that the Trust shall have no responsibility with
respect thereto. SierraCities.com shall promptly pay and discharge, or cause
the payment and discharge of, all federal income taxes (and all other material
taxes) when due and payable by each such Seller, except (i) such as may be paid

any taxing authority. SierraCities.com and the Depositor shall have entered
into a Tax Sharing Agreement, pursuant to which (i) SierraCities.com shall
assume the sole responsibility for making any required payments of taxes to the
Internal Revenue Service and shall agree to indemnify and hold the Depositor
harmless against any claims of liability for such taxes and (ii) the Depositor
shall be required to make certain payments to SierraCities.com in respect of
its separate federal income tax liability. So long as any Notes remain
outstanding, SierraCities.com and the Depositor shall not terminate or amend
such Tax Sharing Agreement without the prior written consent of the Indenture
Trustee, except that SierraCities.com shall not require the Depositor to make
any payments to SierraCities.com, pursuant to the Tax Sharing Agreement, which
exceed the aggregate federal income tax liability of the Depositor, on a
separate return basis for all taxable years covered by the Tax Sharing
Agreement, that would arise if all allowable losses arising at any time during
such period were applied to reduce the Depositor's aggregate separate taxable
income for all such years.

                  (j) Taxes and Other Liabilities. SierraCities.com shall
promptly pay and discharge all material taxes, assessments, fees, claims and
other governmental charges when due and payable by SierraCities.com, the First

faith by appropriate proceedings and for which an adequate reserve has been
established and is maintained in accordance with GAAP. SierraCities.com shall
promptly notify the Trust and the Indenture Trustee of any material challenge,
contest or proceeding pending by or against SierraCities.com or the First
Sierra Group before any taxing authority.

                  (k) Non-Consolidation. SierraCities.com shall be operated in
such a manner that Receivables III and/or the Holding Trust, the holder of the
trust certificate to be issued by the Trust, would not be substantively
consolidated with SierraCities.com, such that the separate corporate existence
of SierraCities.com and Receivables III, on the one hand, and Holding Trust
and/or the Trust, on the other hand, would be ignored in the event of a
bankruptcy of SierraCities.com.

                  (l) No Agency. SierraCities.com will not act as an agent of
Receivables III, Holding Trust or the Trust in any capacity except to the
limited extent provided in the Transaction Documents, but instead will present
itself to the public as a corporation separate from Receivables III and/or
Holding Trust or the Trust;

                  (m) Financial Statements. The financial statements and books
and records of SierraCities.com reflect the separate existence of Receivables
III, Holding Trust and the Trust.

                  SECTION 4.02 Receivables III Covenants. Receivables III
hereby covenants and agrees with the Trust, the Noteholders and the Indenture
Trustee as follows:

                  (a) Obligor's Quiet Enjoyment. Receivables III hereby
acknowledges and agrees that its rights in the Equipment are expressly subject
to the rights of the related Obligors in such Equipment pursuant to the
applicable Contracts. Receivables III covenants and agrees that, so long as an
Obligor shall not be in default of any of the provisions of the applicable
Contract, neither Receivables III nor any assignee of Receivables III will
disturb the Obligor's quiet and peaceful possession of the related Equipment
and the Obligor's use thereof for its intended purpose.

                  (b) Operation of Receivables III. Receivables III shall be
operated in such a manner that it would not be substantively consolidated in
the trust estate of another Person (that is, such that the separate legal
existence of Receivables III and such Person would be disregarded) and in that
regard, Receivables III shall:

                  (i) be a limited purpose corporation whose primary activities
         are restricted in its certificate of incorporation;

                  (ii) not engage in any action that would cause the separate
         legal identity of Receivables III not to be respected, including,
         without limitation, (a) holding itself out as being liable for the
         debts of any other party or (b) acting other than through its duly
         authorized agents;

                  (v) not commingle its funds, assets and records relating
         thereto with those of SierraCities.com or any other entity;

                  (vi) entitle the separate creditors of Receivables III to be
         satisfied out of Receivables III's assets prior to any value in
         Receivables III becoming available to Receivable III's equityholders,
         or SierraCities.com's creditors or Holding Trust's creditors;

                  (vii) act solely in its own name in the conduct of its
         business, including business correspondence and other communications,
         and shall conduct its business so as not to mislead others as to the
         identity of the entity with which they are concerned;

                  (viii) maintain company records and books of account and
         shall not commingle its company records and books of account with the
         records and books of account of any entity;

         connection with or relating to its Certificate of Incorporation and/or
         Bylaws;

                  (x) not form, or cause to be formed, any subsidiaries;

         not fail to comply with the corporate formalities established in, its
         Certificate of Incorporation and/or Bylaws;

                  (xii) maintain its assets separately from the assets of
         SierraCities.com, Holding Trust and First Sierra Healthcare Equipment
         Contract Trust 2000-1 (including, in each case, through the
         maintenance of a separate bank account);

                  (xiii) manage its day-to-day business without the involvement
         of SierraCities.com and/or Holding Trust;

                  (xiv) maintain a separate office from that of
         SierraCities.com and/or Holding Trust;

                  (xv) not act as an agent of SierraCities.com or Holding
         Trust, except to the limited extent provided in the Transaction

                  (c) Merger or Consolidation.

                  (i) Receivables III will keep in full effect its existence,
         rights and franchises as a corporation and will obtain and preserve
         its qualification to do business as a foreign corporation in each
         jurisdiction which permits such qualification and in which it is
         necessary to protect the validity and enforceability of this
         Agreement, any other Transaction Document to which it is a party or
         any of the Contracts and to perform its duties under this Agreement
         and each other Transaction Document to which it is a party.

                  (ii) Any partnership or corporation (i) into which
         Receivables III may be merged or consolidated, (ii) resulting from any
         merger, conversion, or consolidation to which Receivables III shall be
         party, or (iii) succeeding to Receivables III's business substantially
         as a whole, shall execute an agreement of assumption to perform all of
         Receivables III's obligations under this Agreement and any other
         Transaction Document to which Receivables III is a party, and upon
         such execution will be Receivables III's successor under this
         Agreement and any other such Transaction Document, without the
         execution or filing of any document or any further act on the part of
         any of the parties to this Agreement and any other such Transaction
         Document, anything in this Agreement and any other Transaction
         Document to the contrary notwithstanding; provided, however, that (a)
         immediately after giving effect to such transaction, no covenant made
         pursuant to Section 4.02(c) shall have been breached, (b) Receivables
         III shall have delivered to the Trust, the Rating Agencies, the Owner
         Trustee and the Indenture Trustee an Officer's Certificate and an
         opinion of counsel, satisfactory to each of them, each stating that
         such consolidation, conversion, merger, or succession and such
         agreement of assumption comply with this Section 4.02(c) and that all
         conditions precedent, if any, provided for in this Agreement relating
         to such transaction have been complied with, (c) Receivables III shall
         have delivered to the Trust, the Owner Trustee, the Rating Agencies
         and the Indenture Trustee an opinion of counsel, satisfactory to each
         of them, either (1) stating that, in the opinion of such counsel, all
         financing statements and continuation statements and amendments
         thereto have been executed and filed that are necessary fully to
         preserve and protect the interest of the Owner Trustee, on behalf of
         the Trust, in the Contracts and reciting the details of such filings,
         or (2) stating that, in the opinion of such counsel, no such action
         shall be necessary to preserve and protect such interest and (d) such
         partnership or corporation shall have organizational documents with
         similar restrictions as those of Receivables III.

                  (d) Non-Consolidation. Receivables III shall be operated in
such a manner that Holding Trust or the Trust would not be substantively
consolidated with Receivables III, such that the separate corporate existence
of Receivables III, on the one hand, and Holding Trust or the Trust, on the
other hand, would be ignored in the event of a bankruptcy of Receivables III.

                  (e) No Agency. Receivables III will not act as an agent of
Holding Trust or the Trust in any capacity except to the limited extent
provided in the Transaction Documents, but instead will present itself to the
public as a corporation separate from Holding Trust or the Trust.

                  SECTION 4.03 Transfer of Conveyed Assets. Each Seller,
Receivables III and each Investor understands that the Trust intends to pledge
the Pledged Property to the Indenture Trustee on behalf of the Noteholders,
pursuant to the Indenture. Each Seller, Receivables III and each Investor
agrees that such assignee of the Trust may exercise the rights of the Trust
hereunder and shall be entitled to all of the benefits of the Trust hereunder
to the extent provided for in such assignment.

                  (a) All representations and warranties of SierraCities.com,

time to the Owner Trustee, on behalf of the Trust, from each Seller pursuant to
this Agreement meeting the requirements of applicable state law in such manner
in such jurisdictions as are necessary to perfect the transfer of the Initial

such financing statements or other evidence of such filings to the Trust;

                  (e) All corporate and legal proceedings and all instruments

                                  TERMINATION

                  SECTION 6.01 Termination. The respective obligations and
responsibilities of each Seller, SierraCities.com and the Trust created by this
Agreement shall terminate upon the latest of (i) the maturity or other
liquidation of the last Contract and the disposition of any amounts received
upon disposition of any Defaulted Contracts and any Equipment leased
thereunder; and (ii) the termination of the Indenture in accordance with the
terms thereof; provided, however, that the indemnifications contained in

                  SECTION 6.02 Effect of Termination.

                    No termination or rejection or failure to assume the
executory obligations of this Agreement in the bankruptcy of any Seller or the
Trust shall be deemed to impair or affect the obligations pertaining to any
executed sale or executed obligations, including, without limitation,
pre-termination breaches of representations and warranties by any Seller.
Without limiting the foregoing, prior to termination, the failure of
SierraCities.com to pay a Repurchase Amount shall render such transfer or
obligation executory, nor shall the continued duties of the parties pursuant to
Article IV or Section 7.06 of this Agreement render an executed sale executory.

                  Section 1. Conveyance of Subsequent Conveyed Assets.

                  (a) Each of the Sellers does hereby sell, transfer, assign,
set over and convey to the Trust, without recourse, (i) all of its respective
right, title and interest in and to the Subsequent Equipment (except for any
licensed products that may accompany the Equipment) and any new unit or units
of Equipment substituted for any existing unit or units of Equipment, including
all income and proceeds upon any sale or other disposition of the Subsequent
Equipment, (ii) all of its respective right, title and interest in and to, but
not its obligations under, the Subsequent Contracts and all amendments,
additions and supplements including schedules, summary schedules and
subschedules made or hereafter made with respect thereto, (iii) all monies due
or to become due in payment of the Subsequent Contracts on or after the related
Subsequent Cut-Off Date, including without limitation, all Scheduled Payments
thereunder (whether or not due), any Prepayments, any payments in respect of a
casualty or early termination and any Liquidation Proceeds received with
respect thereto, but excluding any Excluded Amounts, (iv) the Contract Files,
(v) all Insurance Proceeds relating to the foregoing and such Seller's rights
and interests in the Insurance Policies relating to the foregoing, (vi) all

                  (b) Intention of the Parties; Grant of Security Interest. It
is the intention of the parties hereto that each transfer of the Conveyed
Assets to be made pursuant to the terms hereof shall constitute an absolute
assignment and a sale of such Contract by each Seller to the Trust and not a
loan. In the event, however, that a court of competent jurisdiction were to
hold that any such transfer constitutes a loan and not a sale, it is the
intention of the parties hereto that this Agreement is deemed to be a security
agreement and that each Seller shall be deemed to have granted to the Trust as
of the date hereof a first priority perfected security interest in all of such
Seller's right, title and interest in, to and under each Conveyed Asset, and
all income and proceeds thereof. Such grant is made to secure the payment of
all amounts payable under this Agreement.

                  (c) The expenses and costs relating to the delivery of the
Subsequent Conveyed Assets, this Agreement and such other items required under
the Receivables Transfer Agreement shall be borne by SierraCities.com.

warranties set forth in Section 3.01 of the Receivables Transfer Agreement that

execution and delivery of this Agreement or by the performance of its
respective obligations hereunder nor is it aware of any pending insolvency; no
petition of bankruptcy (or similar insolvency proceeding) has been filed by or
against any of the Sellers prior to the date hereof;
