Item 2.  Acquisition or Disposition of Assets

Description of the Notes and the Contracts

         First Sierra Receivables II, Inc. and First Sierra Receivables III,
Inc. (the "Depositor" and, together with First Sierra Receivables II, Inc. (the
"Registrants") have registered issuances of an aggregate of up to $1,537,161,697
in principal amount of lease-backed securities, on a delayed or continuous basis
pursuant to Rule 415 under the Securities Act of 1933, as amended (the "Act"),
by a Registration Statement on Form S-3 (Registration File No. 333-12199) (as
amended, the "Registration Statement"). Pursuant to the Registration Statement,
the Depositor formed a trust, the First Sierra Equipment Contract Trust 1998-1,
a common law trust acting through its trustee First Union Trust Company,
National Association, not in its individual capacity but solely as Owner Trustee
(the "Trust"), pursuant to which the Trust issued Notes under an Indenture (the
"Indenture"), attached hereto as Exhibit 4.1, dated as of December 1, 1998, by
and between the Trust, First Sierra Financial, Inc., as servicer and originator
("First Sierra," the "Servicer" and the "Originator") and Bankers Trust Company,
as indenture trustee (the "Trustee"). This Current Report on Form 8-K is being
filed to satisfy an undertaking to file copies of certain agreements executed in
connection with the issuance of the Notes, the forms of which were filed as
Exhibits to the Registration Statement.

         The Notes consist of seven classes, the Class A-1 Notes, Class A-2
Notes, Class A-3 Notes, Class A-4 Notes, Class B-1 Notes, Class B-2 Notes and
Class B-3 Notes. Only the Class A-1 Notes, Class A-2 Notes, Class A-3 Notes and
Class A-4 Notes (the "Class A Notes") were issued pursuant to the Registration
Statement. The Class A-1 Notes represent the right to receive repayment of the
Initial Class A-1 Note Principal Balance ($70,687,140) of the Class A-1 Notes
and monthly interest at a rate of 5.215% per annum on the unpaid portion of such
principal amount, the Class A-2 Notes represent the right to receive repayment
of the Initial Class A-2 Note Principal Balance ($53,856,869) of the Class A-2
Notes and monthly interest at a rate of 5.490% per annum on the unpaid portion
of such principal amount, the Class A-3 Notes represent the right to receive
repayment of the Initial Class A-3 Note Principal Balance ($70,687,140) of the
Class A-3 Notes and monthly interest at a rate of 5.450% per annum on the unpaid
portion of such principal amount and the Class A-4 Notes represent the right to
receive repayment of the Initial Class A-4 Note Principal Balance ($70,687,140)
of the Class A-4 Notes and monthly interest at a rate of 5.628% per annum on the
unpaid portion of such principal amount.

         The rights to receive such payments are based solely upon the interests
represented by the Class A Notes in the Trust Property (the "Trust Property")
which secures the Class A Notes. The assets of the Trust Property will consist
of certain finance leases and commercial loans received after the close of
business on December 1, 1998 (the "Cut-Off Date") (such leases, the
"Contracts"), a security interest in the underlying equipment or property leased
thereby (the "Equipment" and, together with the Contracts, the "Receivables")
and certain other property more fully described in the Prospectus Supplement.

         On December 17, 1998 (the "Closing Date"), the Depositor and certain
trusts sponsored by First Sierra transferred the Contracts and the related
Equipment to the Trust pursuant to the Receivables Transfer Agreement, dated as
of December 1, 1998 (the "Receivables Transfer Agreement"), attached hereto as
Exhibit 10.1, between First Sierra, the Depositor, Prudential Securities Credit
Corporation, First Union National Bank, Variable Funding Capital Corporation,
the Trustee and the Trust.

         Principal and interest will be paid to the Class A Noteholders monthly
on the 12th day (or the next succeeding business day thereafter) of each month,
commencing January 12, 1998 (each, a "Payment Date"), as further described
herein. Interest will accrue on the Class A Notes from Payment Date to Payment
Date, or with respect to the initial Payment Date, from December 17, 1998.


                                       2

         The Class A Notes will be unconditionally and irrevocably guaranteed as
to the payment of scheduled interest and ultimate principal thereon on each
payment date pursuant to the terms of a note insurance policy (the "Note
Insurance Policy") to be issued by MBIA Insurance Corporation and attached
hereto as Exhibit 4.2.

         As of the Closing Date, the Contracts possessed the characteristics
described in the Prospectus dated November 25, 1998 and the Prospectus
Supplement dated December 10, 1998, filed pursuant to Rule 424(b)(2) of the Act.

other amendment to the Registration Statement becomes effective, and when any
supplement to the Prospectus is filed with the Commission, and at the Closing
Date, (i) the Registration Statement, as amended as of any such time, and the
Prospectus, as amended or supplemented as of any such time, will comply in all
material respects with the applicable requirements of the Act and the rules
thereunder and (ii) the Registration Statement, as amended as of any such time,

amendment thereof or supplement thereto in reliance upon and in conformity with
the information furnished in writing to the Company by or on behalf of the
Underwriters specifically for use in connection with the preparation of the

and other) to own its properties and conduct its business as now conducted by
it, and as described in the Prospectus, and is duly qualified to do business in
each jurisdiction in which it owns or leases equipment (to the extent such

does not involve (i) a material risk to, or a material adverse effect on, the
business, properties, financial position, operations or results of operations of
the Company or (ii) any risk whatsoever as to the enforceability of any
Contract.

         D. There are no actions, proceedings or investigations pending, or, to
the knowledge of the Company, threatened, before any court, governmental agency
or body or other tribunal (i) asserting the invalidity of this Agreement, the

consummation of the transactions therein contemplated and compliance with the

adversely affects, or may in the future materially and adversely affect, (i) the
ability of the Company to perform its obligations under the Agreements or (ii)
the business, operations, results of operations, financial position, income,
properties or assets of the Company.

         F. This Agreement has been duly executed and delivered by the Company,

it and as described in the Prospectus and there are no proceedings, pending or,
to the best knowledge of the Company, threatened, relating to the revocation or
modification of any such license, certificate, permit or other authorization

earnings, business or operations of the Company or its subsidiaries, taken as a
whole, from September 30, 1998.

         L. The Agreements will conform in all material respects to the

         M. The Company is not aware of (i) any request by the Commission for
any further amendment of the Registration Statement or the Prospectus or for any
additional information; (ii) the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the institution or
threatening of any proceeding for that purpose; or (iii) any notification with
respect to the suspension of the qualification of the Class A Notes for sale in
any jurisdiction or the initiation or threatening of any proceeding for such
purpose.

         3. Agreements of the Underwriters. Each Underwriter, severally and not
jointly, agrees with the Company that upon the execution of this Agreement and
authorization by each Underwriter of the release of the Class A Notes, each
Underwriter shall offer the Class A Notes for sale upon the terms and conditions
set forth in the Prospectus as amended or supplemented in the amounts set forth
in Annex A hereto.

         4. Purchase, Sale and Delivery of the Class A Notes. The Company hereby
agrees, subject to the terms and conditions hereof, to sell the Class A Notes to
the Underwriters, who, upon the basis of the representations and warranties
herein contained, but subject to the conditions hereinafter stated, hereby
severally and not jointly agree to purchase the principal amount of the Class A
Notes set forth in Annex A hereto. At the time of issuance of the Class A Notes,
the Receivables will be transferred by the Sellers, at the direction of the
Company, to the Trust pursuant to the Receivables Transfer Agreement.

         The Class A Notes to be purchased by each Underwriter will be delivered
by the Company to each Underwriter (which delivery shall be made through the
facilities of The Depository Trust Company ("DTC")) against payment of the
purchase price therefor, equal to $247,169,088.46, by a same day federal funds
wire payable to the order of the Company.

         Settlement shall take place at the offices of Dewey Ballantine, 1301

at such other time thereafter as the Underwriters and the Company determine

Underwriter may request, registered in the name of Cede & Co., as nominee of
DTC.

         The Company agrees to have the Class A Notes available for inspection
and review by the Underwriters in New York City not later than 10 a.m. New York
City time on the business day prior to the Closing Date.

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

         A. The Company will promptly advise each Underwriter and its counsel
(i) when any amendment to the Registration Statement shall have become
effective; (ii) of any request 



                                       5
<PAGE>   6

by the Commission for any amendment to the Registration Statement or the
Prospectus or for any additional information; (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or the institution or threatening of any proceeding for that purpose;
and (iv) of the receipt by the Company of any notification with respect to the
suspension of the qualification of the Class A Notes for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose. The Company will not file any amendment to the Registration Statement
or supplement to the Prospectus after the date hereof and prior to the Closing
Date for the Class A Notes unless the Company has furnished each Underwriter and
its counsel copies of such amendment or supplement for their review prior to
filing and will not file any such proposed amendment or supplement to which such
Underwriter reasonably objects, unless such filing is required by law. The
Company will use its best efforts to prevent the issuance of any stop order
suspending the effectiveness of the Registration Statement and, if issued, to
obtain as soon as possible the withdrawal thereof.

         B. If, at any time during the period in which the Prospectus is
required by law to be delivered, any event occurs as a result of which the
Prospectus as then amended or supplemented would include any untrue statement of
a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary to amend or supplement the
Prospectus to comply with the Act or the rules under the Act, the Company will
promptly prepare and file with the Commission, subject to Paragraph A of this
Section 5, an amendment or supplement that will correct such statement or
omission or an amendment that will effect such compliance and, if such amendment
or supplement is required to be contained in a post-effective amendment to the
Registration Statement, will use its best efforts to cause such amendment of the
Registration Statement to be made effective as soon as possible.

         C. The Company will furnish to each Underwriter, without charge,
executed copies of the Registration Statement (including exhibits thereto) and,
so long as delivery of a Prospectus by the Underwriters or a dealer may be
required by the Act, as many copies of the Prospectus, as amended or
supplemented, and any amendments and supplements thereto as the Underwriters may
reasonably request. The Company will pay the expenses of printing all offering
documents relating to the offering of the Class A Notes.

         D. As soon as practicable, but not later than sixteen months after the
effective date of the Registration Statement, the Company will make generally
available to Class A Noteholders an earnings statement covering a period of at
least twelve months beginning after the effective date of the Registration
Statement which will satisfy the provisions of Section 11(a) of the Act and, at
the option of the Company, will satisfy the requirements of Rule 158 under the
Act.

         E. So long as any of the Class A Notes are outstanding, the Company
will cause to be delivered to each Underwriter (i) all documents required to be
distributed to the Class A Noteholders and (ii) from time to time, any other
information filed with any government or regulatory authority that is otherwise
publicly available, as any of the Underwriters may reasonably request.

         F. The Company, whether or not the transactions contemplated hereunder
are consummated or this Agreement is terminated, will pay all expenses in
connection with the 



                                       6
<PAGE>   7

transactions contemplated herein, including but not limited to the expenses of
printing (or otherwise reproducing) all documents relating to the offering, the
fees and disbursements of its counsel and expenses of each Underwriter incurred
in connection with (i) the issuance and delivery of the Class A Notes; (ii)
preparation of all documents specified in this Agreement; (iii) any fees and
expenses of the Indenture Trustee; (iv) any fees and expenses of the Owner
Trustee; (v) any fees and expenses of the Insurer; and (vi) any fees charged by
investment rating agencies for rating the Class A Notes.

         G. The Company agrees that, so long as any of the Class A Notes shall
be outstanding, it will deliver or cause to be delivered to each Underwriter (i)
the annual statement as to compliance delivered to the Indenture Trustee
pursuant to the Servicing Agreement; (ii) the annual statement of a firm of
independent public accountants furnished to the Indenture Trustee pursuant to
the Servicing Agreement as soon as such statement is furnished to the Company;
and (iii) any information and reports required to be delivered by the Servicer
pursuant to Article 4 of the Servicing Agreement.

         H. The Company will enter into the Agreements and all related
agreements on or prior to the Closing Date.

         I. The Company will endeavor to qualify the Class A Notes for sale to
the extent necessary under any state securities or Blue Sky laws in any
jurisdictions as may be reasonably requested by the Underwriters, if any, and
will pay all expenses (including fees and disbursements of counsel) in
connection with such qualification and in connection with the determination of
the eligibility of the Class A Notes for investment under the laws of such
jurisdictions as the Underwriters may reasonably designate, if any.

         6. Conditions of the Underwriters' Obligation. The obligation of each
Underwriter to purchase and pay for the Class A Notes as provided herein shall
be subject to the accuracy as of the date hereof and the Closing Date (as if
made at the Closing Date) of the representations and warranties of the Company
contained herein (including those representations and warranties set forth in
the Servicing Agreement and the Indenture and incorporated herein), to the
accuracy of the statements of the Company made in any certificate or other
document delivered pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder, and to the following additional

Registration Statement shall have been issued and no proceedings for that
purpose shall have been instituted or threatened, and the Prospectus shall have
been filed pursuant to Rule 424(b).

         B. The Underwriters shall have received the Indenture and the Class A
Notes in form and substance satisfactory to the Underwriters, duly executed by
all signatories required pursuant to the respective terms thereof.

         C. The Underwriters shall have received the favorable opinion of Dewey
Ballantine LLP, counsel to the Company with respect to the following items,
dated the Closing Date, to the effect that:


                                       7

                  (1) The Company has been duly organized and is validly
         existing as a corporation in good standing under the laws of the State
         of Delaware, and is qualified to do business in each state necessary to

         Company has the requisite power and authority to execute and deliver,
         engage in the transactions contemplated by, and perform and observe the

         authorized, executed and delivered by the Company, all requisite
         corporate action having been taken with respect thereto, and each
         constitutes the valid, legal and binding agreement of the Company, and
         would be enforceable against the Company in accordance with their
         respective terms.

                  (3) Neither the transfer of the Receivables to the Trust, the
         issuance or sale of the Class A Notes nor the execution, delivery or
         performance by the Company of, the Agreements (A) conflicts or will
         conflict with or results or will result in a breach of, or constitutes
         or will constitute a default under, (i) any term or provision of the
         certificate of incorporation or bylaws of the Company; (ii) to the best
         of such counsel's knowledge, any term or provision of any material
         agreement, contract, instrument or indenture, to which the Company is a
         party or is bound; or (iii) to the best of such counsel's knowledge,
         any order, judgment, writ, injunction or decree of any court or
         governmental agency or body or other tribunal having jurisdiction over
         the Company; or (B) results in, or will result in the creation or
         imposition of any lien, charge or encumbrance upon the Trust or upon
         the Class A Notes, except as otherwise contemplated by the Indenture.

                  (4) No consent, approval, authorization or order of,
         registration or filing with, or notice to, courts, governmental agency
         or body or other tribunal is required under the laws of the State of
         New York, for the execution, delivery and performance of the
         Agreements, or the offer, issuance, sale or delivery of the Class A
         Notes or the consummation of any other transaction contemplated thereby
         by the Company, except such which have been obtained.

                  (5) There are no actions, proceedings or investigations
         pending or, to such counsel's knowledge, threatened against the Company
         before any court, governmental agency or body or other tribunal (i)
         asserting the invalidity of the Agreements or the Class A Notes; (ii)
         seeking to prevent the issuance of the Class A Notes or the
         consummation of any of the transactions contemplated by the Agreements;
         or (iii) which would materially and adversely affect the performance by
         the Company of obligations under, or the validity or enforceability of,
         the Class A Notes or the Agreements.

                  (6) Except as to any financial or statistical data contained
         in the Registration Statement, to the best of such counsel's knowledge,
         the Registration Statement does not contain any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary in order to make the statements therein not
         misleading.


                                       8
<PAGE>   9

                  (7) To the best of the knowledge of such counsel, the
         Commission has not issued any stop order suspending the effectiveness
         of the Registration Statement or any order directed to any prospectus
         relating to the Class A Notes (including the Prospectus), and has not
         initiated or threatened any proceeding for that purpose.

         In rendering their opinions, the counsel described in this Paragraph C
may rely, as to matters of fact, on certificates of responsible officers of the
Company, the Indenture Trustee and public officials. Such opinions may also
assume the due authorization, execution and delivery of the instruments and
documents referred to therein by the parties thereto other than the Company.

         D. The Underwriters shall have received a letter from Arthur Andersen,
dated on or before the Closing Date, in form and substance satisfactory to the

         F. The Underwriters shall have received from the Company a certificate,
signed by the president, a senior vice president or a vice president of the
Company, dated the Closing Date, to the effect that the signer of such
certificate has carefully examined the Registration Statement and the Agreements
and that, to the best of his or her knowledge based upon reasonable
investigation:

                  (1) the representations and warranties of the Company in this
         Agreement, as of the Closing Date, and in the other Agreements and in
         all related Agreements, as of the date specified in such Agreements,
         are true and correct, and the Company has complied with all the
         agreements and satisfied all the conditions on its part to be performed
         or satisfied at or prior to the Closing Date;

                  (2) there are no actions, suits or proceedings pending, or to
         the best of such officer's knowledge, threatened against or affecting
         the Company which if adversely determined, individually or in the
         aggregate, would be reasonably likely to adversely affect the Company's
         obligations under the Agreements in any material way; and no merger,
         liquidation, dissolution or bankruptcy of the Company is pending or
         contemplated;



                                       9
<PAGE>   10

                  (3) the information contained in the Registration Statement
         relating to the Company and the Receivables is true and accurate in all
         material respects and nothing has come to his or her attention that
         would lead such officer to believe that the Registration Statement
         includes any untrue statement of a material fact or omits to state a
         material fact necessary to make the statements therein not misleading;

                  (4) the information set forth in the List of Contracts
         required to be furnished pursuant to the Receivables Transfer Agreement
         is true and correct in all material respects;

                  (5) there has been no amendment or other document filed
         affecting the articles of incorporation or bylaws of the Company since
         December 1, 1998, and no such amendment has been authorized. No event
         has occurred since November 16, 1998, which has affected the good
         standing of the Company under the laws of the State of Delaware;

                  (6) there has not occurred any material adverse change, or any
         development involving a prospective material adverse change, in the
         condition, financial or otherwise, or in the earnings, business or
         operations of the Company and its subsidiaries, taken as a whole, from
         September 30, 1998; and

                  (7) each person who, as an officer or representative of the
         Company, signed or signs the Registration Statement, the Agreements or
         any other document delivered pursuant hereto, on the date of such
         execution, or on the Closing Date, as the case may be, in connection
         with the transactions described in this Agreement was, at the
         respective times of such signing and delivery, and is now, duly elected
         or appointed, qualified and acting as such officer or representative,
         and the signatures of such persons appearing on such documents are
         their genuine signatures.

         The Company shall attach to such certificate a true and correct copy of
its articles of incorporation and bylaws which are in full force and effect on
the date of such certificate, and a certified true copy of the resolutions of
its Board of Directors with respect to the transactions contemplated herein.

         G. There shall not have occurred any change, or any development
involving a prospective change, in the condition, financial or otherwise, or in
the earnings, business or operations, since September 30, 1998, of (A) the
Company its subsidiaries and affiliates or (B) the Insurer, that is in the
Underwriters' judgment material and adverse and that makes it in the
Underwriters' judgment impracticable to market the Class A Notes on the terms
and in the manner contemplated in the Prospectus.

         H. The Policy relating to the Class A Notes shall have been duly
executed and issued at or prior to the Closing Date and shall conform in all
material respects to the description thereof in the Prospectus.

         I. The Underwriters shall have received a favorable opinion of Kutak
Rock, counsel to the Insurer, dated the Closing Date and in form and substance
satisfactory to counsel for the Underwriters, to the effect that:


                                       10
<PAGE>   11

                  (1) the Insurer is a stock insurance corporation, duly
         incorporated and validly existing under the laws of the State of New
         York. The Insurer is validly licensed and authorized to issue the
         Policy and perform its obligations under the Policy in accordance with
         the terms thereof, under the laws of the State of New York;

                  (2) the execution and delivery by the Insurer of the Policy,
         the Insurance Agreement and the Indemnification Agreement are within
         the corporate power of the Insurer and have been authorized by all
         necessary corporate action on the part of the Insurer; the Policy has
         been duly executed and is the valid and binding obligation of the
         Insurer enforceable in accordance with its terms except that the
         enforcement of the Policy may be limited by laws relating to
         bankruptcy, insolvency, reorganization, moratorium, receivership and
         other similar laws affecting creditors' rights generally and by general
         principles of equity;

                  (3) the Insurer is authorized to deliver the Insurance
         Agreement and the Indemnification Agreement, and the Insurance
         Agreement and the Indemnification Agreement have been duly executed and
         are the valid and binding obligations of the Insurer enforceable in
         accordance with its terms except that the enforcement of the Insurance
         Agreement and the Indemnification Agreement may be limited by laws
         relating to bankruptcy, insolvency, reorganization, moratorium,
         receivership and other similar laws affecting creditors' rights
         generally and by general principles of equity and by public policy
         considerations relating to indemnification for securities law
         violations;

                  (4) no consent, approval, authorization or order of any state
         or federal court or governmental agency or body is required on the part
         of the Insurer, the lack of which would adversely affect the validity
         or enforceability of the Policy; to the extent required by applicable
         legal requirements that would adversely affect the validity or
         enforceability of the Policy, the form of the Policy has been filed
         with, and approved by, all governmental authorities having jurisdiction
         over the Insurer in connection with such Policy;

                  (5) to the extent the Policy constitutes certificates within
         the meaning of Section 2(1) of the Securities Act of 1933, as amended
         (the "Act"), they are certificates that are exempt from the
         registration requirements of the Act; and

                  (6) the information set forth under the caption "THE NOTE
         INSURANCE POLICY AND THE NOTE INSURER" in the Prospectus, insofar as
         such statements constitute a description of the Policy, accurately
         summarizes the Policy.

         In rendering this opinion, such counsel may rely, as to matters of
fact, on certificates of responsible officers of the Company, the Indenture
Trustee, the Insurer and public officials. Such opinion may assume the due
authorization, execution and delivery of the instruments and documents referred
to therein by the parties thereto other than the Insurer.

         J. On or prior to the Closing Date there shall not have occurred any
downgrading, nor shall any notice have been given of (A) any intended or
potential downgrading or (B) any review or possible change in rating the
direction of which has not been indicated, in the



                                       11
<PAGE>   12

rating accorded the Insurer's claims paying ability by any "nationally
recognized statistical rating organization," as such term is defined for
purposes of the Act.

         K. The Underwriter shall have received from the Insurer a certificate,
signed by the President, a senior vice president or a vice president of the
Insurer, dated the Closing Date, to the effect that the signer of such
certificate has carefully examined the Policy, the Insurance Agreement, the
Indemnification Agreement and the related documents and that, to the best of his
or her knowledge based on reasonable investigation:

                  (1) there are no actions, suits or proceedings pending or
         threatened against or affecting the Insurer which, if adversely
         determined, individually or in the aggregate, would adversely affect
         the Insurer's performance under the Policy, the Insurance Agreement or
         the Indemnification Agreement;

                  (2) each person who as an officer or representative of the
         Insurer, signed or signs the Policy, the Insurance Agreement, the
         Indemnification Agreement or any other document delivered pursuant
         hereto, on the date thereof, or on the Closing Date, in connection with
         the transactions described in this Agreement was, at the respective
         times of such signing and delivery, and is now, duly elected or
         appointed, qualified and acting as such officer or representative, and
         the signatures of such persons appearing on such documents are their
         genuine signatures;

                  (3) the information contained in the Prospectus under the
         caption "THE NOTE INSURANCE POLICY AND THE NOTE INSURER" is true and
         correct in all material respects and does not omit to state a material
         fact with respect to the description of the Policy or the ability of
         the Insurer to meet its payment obligations under the Policy;

                  (4) the tables regarding the Insurer's capitalization set
         forth in the Prospectus under the heading "THE NOTE INSURANCE POLICY
         AND THE NOTE INSURER" presents fairly the capitalization of the Insurer
         as of September 30, 1998;

                  (5) on or prior to the Closing Date, there has been no
         downgrading, nor has any notice been given of (A) any intended or
         potential downgrading or (B) any review or possible changes in rating,
         the direction of which has not been indicated, in the rating accorded
         the claims paying ability of the Insurer by any "nationally recognized
         statistical rating organization," as such term is defined for purposes
         of the Act;

                  (6) the consolidated financial statements of the Insurer, a
         wholly owned subsidiary of MBIA Inc., and its subsidiaries as of
         December 31, 1997 and December 31, 1996 and for the three years ended
         December 31, 1997, prepared in accordance with generally accepted
         accounting principles, included in the Annual Report on Form 10-K of
         MBIA Inc., for the year ended December 31, 1997, and the consolidated
         financial statements of the Insurer and its subsidiaries as of
         September 30, 1998 and for the nine-month periods ended September 30,
         1998 and September 30, 1997 included in the Quarterly Report on Form
         10-Q of MBIA Inc. for the period ending September 30, 1998,
         incorporated by referenced into the Prospectus, fairly present in all
         material respects the financial 



                                       12
<PAGE>   13

         condition of the Insurer as of such date and for the period covered by
         such statements in accordance with generally accepted accounting
         principles consistently applied; and

                  (7) to the best knowledge of such officer, since September 30,
         1998, no material adverse change has occurred in the financial position
         of the Insurer other than as set forth in the Prospectus.

The officer of the Insurer certifying to items 5 through 7 shall be an officer
in charge of a principal financial function.

         The Insurer shall attach to such certificate a true and correct copy of
its certificate or articles of incorporation, as appropriate, and its bylaws,
all of which are in full force and effect on the date of such certificate.

         L. The Underwriters shall have received a favorable opinion of counsel
to the Indenture Trustee, dated the Closing Date and in form and substance
satisfactory to the Underwriters, to the effect that:

                  (1) the Indenture Trustee is a banking corporation duly
         organized, validly existing and in good standing under the laws of the
         State of New York and has the power and authority to enter into and to
         take all actions required of it under the Indenture;

                  (2) each of (i) the Indenture, (ii) the Servicing Agreement
         and (iii) the Insurance Agreement has been duly authorized, executed
         and delivered by the Indenture Trustee and each constitutes the legal,
         valid and binding obligation of the Indenture Trustee, enforceable
         against the Indenture Trustee in accordance with its respective terms,
         except as enforceability thereof may be limited by (A) bankruptcy,
         insolvency, reorganization or other similar laws affecting the
         enforcement of creditors' rights generally, as such laws would apply in
         the event of a bankruptcy, insolvency or reorganization or similar
         occurrence affecting the Indenture Trustee, and (B) general principles
         of equity regardless of whether such enforcement is sought in a
         proceeding at law or in equity;

                  (3) no consent, approval, authorization or other action by any
         governmental agency or body or other tribunal is required on the part
         of the Indenture Trustee in connection with its execution and delivery
         of the Indenture, the Servicing Agreement or the Insurance Agreement or
         the performance of its obligations thereunder;

                  (4) the Notes have been duly executed, authenticated and
         delivered by the Indenture Trustee and assuming delivery and payment
         are validly issued therefor and outstanding and are entitled to the
         benefits of the Indenture; and

                  (5) the execution and delivery of, and performance by the
         Indenture Trustee of its obligations under, the Indenture, the
         Servicing Agreement or the Insurance Agreement do not conflict with or
         result in a violation of any statute or regulation applicable to the
         Indenture Trustee, or the charter or bylaws of the Indenture Trustee,
         or to the best knowledge of such counsel, any governmental authority
         having jurisdiction 



                                       13
<PAGE>   14

         over the Indenture Trustee or the terms of any indenture or other
         agreement or instrument to which the Indenture Trustee is a party or by
         which it is bound.

         In rendering such opinion, such counsel may rely, as to matters of
fact, on certificates of responsible officers of the Company, the Indenture
Trustee and public officials. Such opinion may also assume the due
authorization, execution and delivery of the instruments and documents referred
to therein by the parties thereto other than the Indenture Trustee.

         M. The Underwriters shall have received from the Indenture Trustee a
certificate, signed by the president, a senior vice president or a vice
president of the Indenture Trustee, dated the Closing Date, to the effect that
each person who, as an officer or representative of the Indenture Trustee,
signed or signs the Notes, the Indenture, the Servicing Agreement or any other
document delivered pursuant hereto, on the date hereof or on the Closing Date,
in connection with the transactions described in the Indenture was, at the
respective times of such signing and delivery, and is now, duly elected or
appointed, qualified and acting as such officer or representative, and the
signatures of such persons appearing on such documents are their genuine
signatures.

         N. The Underwriters shall have received a favorable opinion of counsel
to the Owner Trustee, dated the Closing Date and in form and substance
satisfactory to the Underwriters, to the effect that:

                  (1) The Owner Trustee is duly incorporated, validly existing
         and in good standing as a banking corporation under the laws of the
         State of Delaware.

                  (2) The Owner Trustee has the power and authority to execute,
         deliver and perform the Trust Agreement, the Receivables Transfer
         Agreement, the Servicing Agreement and the Indenture (collectively, the
         "Owner Trustee Agreements").

                  (3) Each of the Owner Trust Agreements has been duly
         authorized, executed and delivered by the Owner Trustee and constitutes
         a legal, valid and binding obligation of the Owner Trustee, enforceable
         against the Owner Trustee, in accordance with its terms.

                  (4) To the best of counsel's knowledge, without independent
         investigation, neither the execution or delivery by the Owner Trustee
         of the Owner Trustee Agreements nor the compliance by the Owner Trustee
         with any of the terms thereof or consummation of the transactions
         contemplated thereby requires the consent or approval of, the giving of
         notice to, the registration with, or the taking of any action with
         respect to, any governmental authority or agency under the laws of the
         State of Delaware.

                  (5) Neither the execution, delivery and performance by the
         Owner Trustee of the Owner Trustee Agreements, nor the consummation of
         the transactions contemplated thereby, nor compliance with the terms
         thereof, will violate or result in a breach of, or constitute a default
         under the provisions of such Owner Trustee Agreements or the articles
         of association or by-laws of the Owner Trustee or, to the best of
         counsel's knowledge, without independent investigation, any law, rule
         or regulation of the State of Delaware applicable to the Owner Trustee.


                                       14
<PAGE>   15

         O. The Underwriters shall have received from the Owner Trustee a
certificate, signed by the president, a senior vice president or a vice
president of the Owner Trustee, dated the Closing Date, to the effect that each
person who, as an officer or representative of the Owner Trustee, signed or
signs the Certificates, the Owner Trustee Agreements or any other document
delivered pursuant hereto, on the date hereof or on the Closing Date, in
connection with the transactions described in the Indenture was, at the
respective times of such signing and delivery, and is now, duly elected or
appointed, qualified and acting as such officer or representative, and the
signatures of such persons appearing on such documents are their genuine
signatures.

         P. The Underwriters shall have received from Dewey Ballantine LLP,
special counsel to the Underwriters, such opinion or opinions, dated the Closing
Date, with respect to the issuance and sale of the Class A Notes, the Prospectus
and such other related matters as the Underwriters shall reasonably require.

         Q. The Underwriters and their counsel shall have received copies of any
opinions of counsel to the Company or the Indenture Trustee supplied to the
Indenture Trustee relating to matters with respect to the Notes, the formation
of the Trust or the acquisition of the Receivables. Any such opinions shall be
satisfactory to the Underwriters in form and substance.

         R. The Underwriters shall have received an opinion from Dewey
Ballantine LLP, special tax counsel to the Company to the effect that the
statements in the Prospectus Supplement under the heading "CERTAIN FEDERAL
INCOME TAX CONSIDERATIONS" accurately describe the material federal income tax
consequences to the holders of the Class A Notes.

         S. The Underwriters shall have received such further information,
certificates and documents as the Underwriters may reasonably have requested not
fewer than three (3) full business days prior to the Closing Date.

         If any of the conditions specified in this Section 6 shall not have
been fulfilled in all respects when and as provided in this Agreement, if the
Company is in breach of any covenants or agreements contained herein or if any
of the opinions and certificates mentioned above or elsewhere in this Agreement
shall not be in all material respects reasonably satisfactory in form and
substance to the Underwriters and their counsel, this Agreement and all
obligations of the Underwriters hereunder, may be canceled on, or at any time
prior to, the Closing Date by the Underwriters. Notice of such cancellation
shall be given to the Company in writing, or by telephone or telegraph confirmed
in writing.

         7. Expenses. If the sale of the Class A Notes provided for herein is
not consummated by reason of a default by the Company in its obligations
hereunder, then the Company will reimburse the Underwriters, upon demand, for
all reasonable out-of-pocket expenses (including, but not limited to, the
reasonable fees and expenses of counsel for the Underwriters) that shall have
been incurred by it in connection with its investigation with regard to the
Company and the Class A Notes and the proposed purchase and sale of the Class A
Notes.


                                       15
<PAGE>   16

         8. Indemnification and Contribution.

         A. Regardless of whether any Class A Notes are sold, the Company will
indemnify and hold harmless each Underwriter, each of their respective officers
and directors and each person who controls each Underwriter within the meaning
of the Act or the Securities Exchange Act of 1934 (the "1934 Act"), against any
and all losses, claims, damages, or liabilities (including the cost of any
investigation, legal and other expenses incurred in connection with and amounts
paid in settlement of any action, suit, proceeding or claim asserted), joint or
several, to which they may become subject, under the Act, the 1934 Act or other
federal or state law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained (i) in the Registration Statement, or any amendment
thereof or supplement thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact necessary to make the
statements therein, not misleading or (ii) in the Basic Prospectus or the
Prospectus Supplement or any amendment thereto or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and will reimburse
each such indemnified party for any legal or other expenses reasonably incurred
by it in connection with investigating or defending against such loss, claim,
damage, liability or action; provided, however, that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information relating to the Underwriter furnished to the
Company by such Underwriter specifically for use in connection with the
preparation thereof.

         B. Regardless of whether any Class A Notes are sold, each Underwriter,
severally and not jointly, will indemnify and hold harmless the Company, each of
its officers and directors and each person, if any, who controls the Company
within the meaning of the Act or the 1934 Act against any losses, claims,
damages or liabilities to which they become subject under the Act, the 1934 Act
or other federal or state law or regulation, at common law or otherwise, to the
same extent as the foregoing indemnity, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in (i)
the Registration Statement, or any amendment thereof or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact necessary to make the statements therein not misleading or in
(ii) the Basic Prospectus or the Prospectus Supplement or any amendment thereto
or supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
therein in reliance upon and in conformity with written information relating to
the Underwriter furnished to the Company by such Underwriter specifically for
use in the preparation thereof and so acknowledged in writing, and will
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending against such loss, claim,
damage, liability or action.

         C. In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to paragraphs 



                                       16
<PAGE>   17

A, B and E of this Section 8, such person (hereinafter called the indemnified
party) shall promptly notify the person against whom such indemnity may be
sought (hereinafter called the indemnifying party) in writing thereof; but the
omission to notify the indemnifying party shall not relieve such indemnifying
party from any liability which it may have to any indemnified party otherwise
than under such Paragraph. The indemnifying party, upon request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such proceeding
any indemnified party shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such indemnified
party unless (i) the indemnifying party and the indemnified party shall have
mutually agreed to the retention of such counsel, or (ii) the named parties to
any such proceeding (including any impleaded parties) include both the
indemnifying party and the indemnified party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the indemnifying party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all such indemnified parties, and that
all such fees and expenses shall be reimbursed as they are incurred. Such firm
shall be designated in writing by the Underwriters in the case of parties
indemnified pursuant to paragraph A of this Section 8 and by the Company in the
case of parties indemnified pursuant to paragraphs B and E of this Section 8.
The indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. Notwithstanding the foregoing sentence, if at
any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
above, the indemnifying party agrees that it shall be liable for any settlement
of any proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party,
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

         D. Each Underwriter agrees, severally and not jointly, to provide the
Company no later than the date on which the Prospectus Supplement is required to
be filed pursuant to Rule 424 with a copy of any Derived Information (defined
below) for filing with the Commission on Form 8-K.

         E. Each Underwriter agrees, jointly and not severally, assuming all
Company-Provided Information (defined below) is accurate and complete in all
material respects, to indemnify and hold harmless the Company, its respective
officers and directors and each person who controls the Company within the
meaning of the Securities Act or the Exchange Act against any and all losses,
claims, damages 



                                       17
<PAGE>   18

or liabilities, joint or several, to which they may become subject under the
Securities Act or the Exchange Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement of a material fact contained in the Derived
Information provided by such Underwriter, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and agrees to
reimburse each such indemnified party for any legal or other expenses reasonably
incurred by him, her or it in connection with investigating or defending or
preparing to defend any such loss, claim, damage, liability or action as such
expenses are incurred. The several obligations of each Underwriter under this
Section 8(E) shall be in addition to any liability which each Underwriter may
otherwise have.

         The procedures set forth in Section 8(C) shall be equally applicable to
this Section 8(E).

         F. For purposes of this Section 8, the term "Derived Information" means
such portion, if any, of the information delivered to the Companies pursuant to
Section 8(D) for filing with the Commission on Form 8-K as: (i) is not contained
in the Prospectus without taking into account information incorporated therein
by reference; and (ii) does not constitute Company-Provided Information.
"Company-Provided Information" means any computer tape furnished to the
Underwriters by the Company concerning the assets comprising the Trust.

         G. If the indemnification provided for in this Section 8 is unavailable
to an indemnified party in respect of any losses, claims, damages or liabilities
referred to herein, then each indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company and each Underwriter from the sale of the Class A Notes or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only relative benefits
referred to in clause (i) above but also the relative fault of the Company and
of each Underwriter in connection with the statements or omissions that resulted
in such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative benefits received by the Company and each
Underwriter shall be deemed to be in such proportion so that each Underwriter is
responsible for that portion determined by multiplying the total amount of such
losses, claims, damages and liabilities, including legal and other expenses, by
a fraction, the numerator of which is (x) the excess of the Aggregate Resale
Price (as defined below) of the Class A Notes underwritten by such Underwriter
over the aggregate purchase price of such Class A Notes specified in Section 4
of this Agreement and the related Prospectus Supplement, and the denominator of
which is (y) the Aggregate Resale Price of such Class A Notes, and the Company
is responsible for the balance; provided, however, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of the immediately preceding
sentence, the "Aggregate Resale Price" of the Class A Notes at the time of any
determination shall be the weighted average of the purchase prices (in each case
expressed as a percentage of the aggregate principal amount of the Class A Notes
so purchased), determined on the basis of such principal amounts, paid to the
Underwriter by all subsequent purchasers that purchased the Class A Notes on or
prior to such date of determination. The relative fault of the Company and each
Underwriter shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material 



                                       18
<PAGE>   19

fact relates to information supplied by the Company or by any of the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

         H. The Company and each Underwriter agree that it would not be just and
equitable if contribution pursuant to this Section 8 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph G of this Section 8. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in paragraph G of this Section 8
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, none of the Underwriters shall
be required to contribute any amount by which the Aggregate Resale Price exceeds
the amount of any damages that such Underwriter has otherwise been required to
pay by reason of any untrue or alleged untrue statement or omission or alleged
omission.

         I. The Company and each Underwriter each expressly waive, and agree not
to assert, any defense to their respective indemnification and contribution
obligations under this Section 8 which they might otherwise assert based upon
any claim that such obligations are unenforceable under federal or state
securities laws or by reasons of public policy.

         J. The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls the
Underwriter within the meaning of the Act or the 1934 Act; and the obligations
of the Underwriters under this Section 8 shall be in addition to any liability
that the Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company and to each person, if any, who
controls the Company within the meaning of the Act or the 1934 Act; provided,
however, that in no event shall the Company or any of the Underwriters be liable
for double indemnification.

         9. Information Supplied by Underwriters. The statements set forth on
the front cover page of the Prospectus Supplement regarding market-making and
under the heading "Method of Distribution" in the Prospectus Supplement (to the
extent such statements relate to the Underwriter) constitute the only
information furnished by the Underwriters to the Company for the purposes of
Sections 2(B) and 8(A) hereof. Each Underwriter confirms that such statements
(to such extent) are correct.

         10. Notices. All communications hereunder shall be in writing and, if
sent to the Underwriters, shall be mailed or delivered or telecopied and
confirmed in writing to Wheat First Securities, Inc., doing business as First
Union Capital Markets, a division of Wheat First Securities, Inc., One First
Union Center, TW-06, Charlotte, North Carolina 28288, Attention: Leah Torstrick;
and, if sent to the Company, shall be mailed, delivered or telegraphed and
confirmed in writing to First Sierra Financial, Inc., 600 Travis Street, Suite
7050, Houston, Texas 77002, Attention: Roger Gebhart.

         11. Survival. All representations, warranties, covenants and agreements
of the Company contained herein or in agreements or certificates delivered
pursuant hereto, the 



                                       19
<PAGE>   20

agreements of the Underwriters and the Company contained in Section 8 hereof,
and the agreement of the Underwriters contained in Section 3 hereof, shall
remain operative and in full force and effect regardless of any investigation
made by or on behalf of the Underwriters or any controlling persons, or any
subsequent purchaser or the Company or any of its officers, directors or any
controlling persons, and shall survive delivery of and payment for the Class A
Notes. The provisions of Sections 5, 7 and 8 hereof shall survive the
termination or cancellation of this Agreement.

         12. Termination. The Underwriters shall have the right to terminate
this Agreement by giving notice as hereinafter specified at any time at or prior
to the Closing Date if (a) trading generally shall have been suspended or
materially limited on or by, as the case may be, the New York Stock Exchange or
the American Stock Exchange, (b) trading of any securities of the Company shall
have been suspended on any exchange or in any over-the-counter market, (c) a
general moratorium on commercial banking activities shall have been declared by
either federal or New York State authorities, (d) there shall have occurred any
outbreak or escalation of hostilities or any change in financial markets or any
calamity or crisis which, in the Underwriters' reasonable judgment, is material
and adverse, and, in the case of any of the events specified in clauses (a)
through (d), such event singly or together with any other such event makes it in
the Underwriters' reasonable judgment impractical to market the Class A Notes.
Any such termination shall be without liability of any other party except that
the provisions of Paragraph G of Section 5 (except with respect to expenses of
the Underwriters) and Sections 7 and 8 hereof shall at all times be effective.

         This Agreement will inure to the benefit of and be binding upon the
signatories hereto and their respective successors and assigns (which successors
and assigns do not include any person purchasing a Class A Note from the
Underwriters), and the officers and directors and controlling persons referred
to in Section 8 hereof and their respective successors and assigns, and no other
persons will have any right or obligations hereunder.

         14. APPLICABLE LAW; VENUE. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK. ANY
ACTION OR PROCEEDING BROUGHT TO ENFORCE OR ARISING OUT OF ANY PROVISION OF THIS
AGREEMENT SHALL BE BROUGHT ONLY IN A STATE OR FEDERAL COURT LOCATED IN THE
BOROUGH OF MANHATTAN, NEW YORK CITY, NEW YORK, AND THE PARTIES HERETO EXPRESSLY
CONSENT TO THE JURISDICTION OF SUCH COURTS AND AGREE TO WAIVE ANY DEFENSE OR
CLAIM OF FORUM NON CONVENIENS THEY MAY HAVE WITH RESPECT TO ANY SUCH ACTION OR
PROCEEDING BROUGHT.

         15. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall together constitute but one and the same
instrument.

         16. Amendments and Waivers. This Agreement may be amended, modified,

         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 Trust Property and provide no recourse against First Sierra, the
Depositor, the Servicer, the Indenture Trustee, the Owner Trustee or any other
Person other than the Note Insurer under the Note Insurance Policy.

         (b) Neither First Sierra, 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, 5.05, 5.07 and
5.08 of the Servicing Agreement and Section 4.01(g) of the Receivables Transfer
Agreement. Without limiting the generality of the foregoing, if any Obligor
fails to pay any Scheduled Payment, Final Scheduled Payment or other amounts due
under a Contract, then neither the Indenture Trustee nor the Noteholders will
have any recourse against First Sierra or the Servicer for such Scheduled
Payment, Final Scheduled Payment, other amounts due under the Contract or any
losses, damages, claims, liabilities or expenses incurred by the Indenture
Trustee or any Noteholder as a direct or indirect result thereof, except as may
be provided for in Article VI hereof and Sections 5.01, 5.03, 5.05, 5.07 and
5.08 of the Servicing Agreement and Section 4.01(g) of the Receivables Transfer
Agreement.

         (c) The Indenture Trustee agrees that in the event of a default by an
Obligor under the terms of a Contract, which default is not cured within any
applicable cure period set forth in such Contract, the Indenture Trustee and the
Noteholders shall be expressly limited to the sources of payment specified
herein. In addition, the Indenture Trustee shall have the right to exercise the
rights of the Originator 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, the Note Insurer or any Noteholder of any
obligation (except for the obligation not to disturb an Obligor's right of quiet
enjoyment) of the Originator 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 Subordinate 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
Subordinate 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 



                                       5
<PAGE>   12

of the Subordinate 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 First Sierra, any
other obligor upon the Notes or an Affiliate of First Sierra 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.

                     ACCOUNTS; ALLOCATION AND APPLICATION OF

         Section 3.01 Collection Account. (a) The Servicer shall establish and

the Noteholders and the Note Insurer as an Eligible Bank Account, in the name of

trust for the registered holders of Equipment Contract-Backed Notes." At the
Servicer's written direction, the Indenture Trustee shall make withdrawals from
the Collection Account only as provided in this Indenture. The Indenture Trustee
shall possess all right, title and interest in all funds on deposit from time to
time in the Collection Account and all proceeds thereof. The Collection Account
shall be under the sole dominion and control of the Indenture Trustee for the
benefit of the Noteholders and the Note Insurer.

         (b) At the times indicated in this Section 3.01(b) or in Section
3.01(c) below, the following amounts (net of Excluded Amounts) shall be
deposited in the Collection Account in immediately available funds:

                  (i) The Servicer shall deposit or cause to be deposited the
         aggregate amounts of Actual Payments;

                  (ii) The Servicer shall deposit the aggregate Servicer

                  (iv) Investment Earnings, as described in Section 3.02(a)

deposit the aggregate amount of Servicer Advances no later than one day prior to
the related Payment Date. The Servicer shall instruct the Indenture Trustee in
writing to deposit the portion of any Advance Payment due and owing for a
Collection Period no later than the related Determination Date. Except as
otherwise expressly set forth, any other deposits and transfers of funds to be

Business Day immediately preceding the related Payment Date.

         Notwithstanding the foregoing, the Servicer may deduct from amounts
otherwise payable to the Collection Account amounts previously deposited by the
Servicer into the Collection Account but (i) subsequently uncollectable as a
result of dishonor of the instrument of payment for or on behalf of the Obligor
or (ii) later determined to have resulted from mistaken deposits.

         Section 3.02 Investment of Monies Held in the Accounts; Subaccounts.
(a) The Servicer shall direct the Indenture Trustee in writing to invest the
amounts in any Account in Eligible Investments that mature not later than the
Business Day immediately preceding the next Payment Date following the

of prior to their maturities. Investment Earnings on amounts held in any Account
shall be deposited in the Collection Account as earned. The amount of any
Insured Payment shall be held uninvested.

         (b) The Indenture Trustee and the Servicer may, from time to time and
in connection with the administration of any Account, establish and maintain
with the Indenture Trustee one or more sub-accounts of any of the Accounts, as
the Indenture Trustee and/or the Servicer may consider useful.

         Section 3.03 The Note Insurance Policy

         (a) On each Determination Date, the Servicer shall determine with
respect to the immediately following Payment Date, the amounts to be on deposit
in the Collection Account on such Payment Date with respect to the immediately
preceding Collection Period and equal to the total of (A) Available Funds with
respect to such Collection Period minus (B) the Trust Operating Expenses (the
"Available Distribution Amount") and shall inform the Indenture Trustee in
writing no later than 10:00 a.m., New York City time, on such Determination Date
of the results of such determination.

         (b) If the Class A Insured Distribution Amount for any Payment Date
exceeds the Available Distribution Amount for such Payment Date (such event
being an "Available Funds Shortfall"), the Indenture Trustee shall complete a
Notice in the form of Exhibit A to the Note Insurance Policy and submit such
notice to the Note Insurer via facsimile transmission no later than 12:00 noon
New York City time on the second Business Day preceding such Payment Date as a
claim for an Insured Payment in an amount equal to such Available Funds
Shortfall.

         (c) Upon receipt of Insured Payments from the Note Insurer, the
Indenture Trustee shall immediately deposit such Insured Payments in the
Collection Account and shall distribute such Insured Payments, or the proceeds
thereof, in accordance with Section 3.04 hereof to the Class A Noteholders
exclusively. The parties hereto recognize that the making of 



                                       7
<PAGE>   14

an Insured Payment does not relieve any of the parties hereto of any obligation
hereunder or under any of the Transaction Documents.

         (d) The Indenture Trustee shall (x) receive Insured Payments as
attorney-in-fact of each of the Class A Noteholders and (y) disburse such
Insured Payment to the Class A Noteholders as set forth in Section 3.04 hereof.
The Note Insurer shall be entitled to receive the related Reimbursement Amount
pursuant to Sections 3.04(b)(xiii) hereof with respect to each Insured Payment
made by the Note Insurer. The Indenture Trustee hereby agrees on behalf of each
Class A Noteholder and the Trust for the benefit of the Note Insurer that it
recognizes that to the extent the Note Insurer makes Insured Payments, either
directly or indirectly (as by paying through the Indenture Trustee), to the
Class A Noteholders, the Note Insurer will be entitled to receive the related
Reimbursement Amount pursuant to Sections 3.04(b)(xiii) hereof.

         (e) The Class A Notes will be insured by the Note Insurance Policy
pursuant to the terms set forth therein, notwithstanding any provisions to the
contrary contained in this Indenture. All amounts received under the Note
Insurance Policy shall be used solely for the payment to Class A Noteholders of
principal at maturity and interest on the Class A Notes.

         (f) If a Responsible Officer of the Indenture Trustee at any time has
actual knowledge that there will not be sufficient moneys in the Collection
Account to make all required payments of principal and interest to the Class A
Noteholders on the applicable Payment Date, the Indenture Trustee shall
immediately notify the Note Insurer or its designee by telephone, promptly
confirmed in writing by overnight mail or facsimile transmission, of the amount
of such deficiency. In addition, if a Responsible Officer of the Indenture
Trustee has actual notice that any of the Class A Noteholders have been required
to disgorge payments of principal or interest on the Class A Note pursuant to a
final judgment by a court of competent jurisdiction that such payment
constitutes a voidable preference to such Holders within the meaning of any
applicable bankruptcy laws, then the Indenture Trustee shall notify the Note
Insurer or its designees of such fact by telephone, promptly confirmed in
writing by overnight mail or facsimile transmission. Such notice shall be in
addition to the procedures set forth in the Note Insurance Policy for making a
claim under the Note Insurance Policy.

         (g) The parties hereto recognize that, to the extent that the Note
Insurer makes payments, directly or indirectly, on account of principal of or
interest on the Class A Notes, the Note Insurer shall be subrogated to the
rights of the Holders of the Class A Notes to receive distributions of principal
and interest in accordance with the terms hereof.

         (h) The parties hereto grant to the Note Insurer the right of prior
approval of amendments or supplements to the Transaction Documents and of the
exercise of any option, vote, right, power or the like available to the Class A
Noteholders hereunder.

         Section 3.04 Disbursements From Collection Account. (a) On each Payment
Date, the Indenture Trustee shall pay the entire amount of money then on deposit
in the Collection Account with respect to the related Collection Period, as
indicated on the Monthly Statement, as applicable, to the Persons to which such
money is then due, calculated on the basis of and in accordance with the Monthly
Statement for the related Collection Period; provided, however, that in the
event the Servicer fails to deliver a Monthly Statement by a Payment Date 



                                       8
<PAGE>   15

the Indenture Trustee shall, nevertheless, pay interest on each Class of Notes
from the sources of funding set forth herein, in each case in an amount with
respect to each Class equal to the product of (i) one-twelfth, (ii) the related
Note Rate and (iii) the related Note Principal Balance, as reflected on the
Monthly Statement most recently delivered by the Servicer (net of any principal
payments in respect thereof on the immediately preceding Payment Date).

the following Persons, in the following order of priority, without duplication:

         inadvertently deposited in the Collection Account;

                  (iii) From the Available Funds then remaining in the
         Collection Account, to the Servicer by wire transfer to the account
         designated in writing by the Servicer of immediately available funds,
         the aggregate amount of the following:

                           (A) An amount equal to the unreimbursed Servicer

         Period;

                  (ix) From the Available Funds then remaining in the Collection
         Account, to the extent that such disbursement shall not result in an
         Available Funds Shortfall, from Available Funds then remaining in the

         (b) By January 31 of each calendar year, commencing January 31, 1999,
or as otherwise required by applicable law, the Indenture Trustee shall furnish
to each Person who at any time during the immediately preceding calendar year
was a Noteholder a statement prepared by the Servicer, and delivered to the
Indenture Trustee, containing the applicable aggregate amounts with respect to
such Noteholder hereof for such calendar year or, in the event such Person was a
Noteholder during a portion of such calendar year, for the applicable portion of
such year, for the purposes of such Noteholder's preparation of federal income
tax returns. In addition to the foregoing the Servicer and the Indenture Trustee
(to the extent the Servicer has provided the necessary information to the
Indenture Trustee) shall make available to Noteholders or the Note Insurer any
other information provided to the Servicer or the Indenture Trustee or otherwise
in the Indenture Trustee's possession reasonably requested by Noteholders or the
Note Insurer in connection with tax matters, in accordance with the written
directions of the Servicer.

         (c) The Servicer shall furnish to each Subordinate Noteholder, on
request, during the term of this Indenture, such periodic, special or other
reports or information not specifically provided for herein, as shall be
necessary, reasonable or appropriate with respect to such Subordinate Noteholder
all such reports or information to be provided by and in accordance 



                                       13
<PAGE>   20

with such applicable instructions and directions as the Subordinate Noteholder
may reasonably require and as the Servicer may reasonably be able to produce;
provided, however, that the Servicer may require such Subordinate Noteholder to
execute a confidentiality agreement in form and substance acceptable to the
Servicer.

         (d) The Indenture Trustee shall promptly send to each Noteholder and
the Note Insurer and to the Rating Agencies in writing:

                  (i) Notice of any breach by First Sierra, the Depositor, the
         Trust, the Originator or the Servicer of any of their respective
         representations, warranties and covenants made herein, the Servicing
         Agreement or in the Receivables Transfer Agreement.

                  (ii) A copy of each Servicer compliance statement delivered to
         the Indenture Trustee pursuant to Section 4.08 of the Servicing
         Agreement.;

                  (iii) Notice of any breach by the Indenture Trustee of its
         representations and warranties set forth in Section 7.17 hereof of
         which a Responsible Officer has actual knowledge;

                  (iv) Notice of the occurrence of any Event of Default (which
         shall also be given to the Rating Agencies);

                  (v) Notice of any Event of Servicing Termination, default
         under the Insurance Agreement or any other default under any of the
         Transaction Documents; and

                  (vi) Notice of the resignation or removal of the Indenture
         Trustee;

provided, however, that in each case the Indenture Trustee shall only be
required to send such notices and other items to the Subordinate Noteholders to
the extent that the Indenture Trustee has itself received the related
information and the Subordinate Noteholders have not already received such
notice or other items. Except as may be specifically provided herein, the
Indenture Trustee shall have no obligation to seek to obtain any such
information.



                                       14

         Section 3.06 Compliance With Withholding Requirements. Notwithstanding
any other provisions of this Indenture, the Indenture Trustee, as paying agent
for and on behalf of, and at the direction of the Servicer, shall comply with
all federal withholding requirements respecting payments (or advances thereof)
to Noteholders as may be applicable to instruments constituting indebtedness for
federal income tax purposes. Any amounts so withheld shall be treated as having
been paid to the related Noteholder for all purposes of this Indenture. In no
event shall the consent of Noteholders be required for any withholding.


                                   ARTICLE IV.

                        REMOVAL OF NON-CONFORMING PLEDGED
                       PROPERTY; SUBSTITUTION OF CONTRACTS

         Section 4.01 Removal of Non-Conforming Pledged Property. (a) Upon
discovery by the Trust, the Note Insurer, the Servicer (or any of its successors
or assigns) or in the case of the Indenture Trustee, upon actual knowledge of a
Responsible Officer of the Indenture Trustee, of a breach of any of the
representations or warranties set forth in Section 2.02 of the Servicing
Agreement that materially and adversely affects any Contract, the related
Equipment or the related Contract File, as the case may be, or if the Servicer
fails to cause delivery of evidence of filing or copies of any UCC financing
statement or delivery of any Certificate of Title in accordance with the
Servicing Agreement (any such event, a "Warranty Event"), the party (including
any such successor or assign) discovering such breach shall give prompt written
notice to the other parties. The Note Insurer in its reasonable discretion shall
then determine whether the related Contract, Equipment or Contract File has been
materially and adversely affected by such breach of a representation or warranty
set forth in Section 2.02 of the Servicing Agreement. As of the last day of the
calendar month following the month of its discovery or its receipt of notice of
breach (or, at First Sierra's election, any earlier date), First Sierra shall
deposit (or cause to be deposited) in 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 be a Defaulted Contract for purposes of this
Article IV.

         (b) The obligation of First Sierra to remove any Trust Property from
the Trust and to remit the Repurchase Amount, as appropriate, with respect to
the related Contract as to which a breach has occurred and is continuing shall
constitute the sole remedy against First Sierra 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 First Sierra.

         Section 4.02 Substitution of Contracts. (a) Subject to the provisions
of Sections 4.02(b) through (d) hereof, First Sierra, upon notice from the
Servicer and with the consent of the Note Insurer, may substitute one or more
Contracts (each a "Substitute Contract") and transfer all of its right, title
and interest in the related Equipment for and replace Contracts and terminate
the security interest in the related Equipment that (i) becomes a Defaulted
Contract or an Early Termination Contract or (ii) are the subject of a
Prepayment, a Casualty Loss or a Warranty Event.


                                       15
<PAGE>   22

         (b) Each Substitute Contract shall be a Contract, with respect to which
all of the representations and warranties set forth in Section 2.02 of the
Servicing Agreement were true as of the related Substitute Contract Cut-Off
Date.

         (c) Prior to any substitution pursuant to this Section 4.02, the
Indenture Trustee shall have received an executed transfer agreement between the
Trust and First Sierra providing for the unconditional sale and transfer of the
Substitute Contracts and related Equipment by First Sierra to the Trust, the
List of Substitute Contracts reflecting the substitution, 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 Transfer Date if:

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

                  (ii) as of the related Substitute Cut-Off Date, the Substitute
         Contracts then being transferred have a Discounted Contract Principal
         Balance not less than the Discounted Contract Principal Balance of the
         Contracts being replaced; 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.

         (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 all proceeds
thereon shall be terminated and such replaced Contract and the related Equipment
shall be transferred to the Trust.

         Section 4.03 Release of Trust Property. (a) The Indenture Trustee when
required by the Trust and the provisions of this Indenture shall execute
instruments provided to it in order to release property from the lien of this
Indenture, in a manner and under circumstances that are not inconsistent with
the provisions of this Indenture and the Servicing Agreement. No party 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 and the Note Insurer pursuant
to the Insurance Agreement have each been paid, release any remaining portion of
the Trust 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 and any subaccounts thereof as may have been
established pursuant to Section 3.02(b). The Indenture Trustee shall release
property from the lien of this Indenture pursuant to this Section 4.03(b) only
upon receipt of an Issuer Request 



                                       16
<PAGE>   23

accompanied by an Officer's Certificate, an Opinion of Counsel and (if required
by the TIA) Independent Certificates in accordance with TIA ss.ss. 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, the Initial Class A-3 Note Principal Balance, the Initial
Class A-4 Note Principal Balance and the Subordinate Notes will be issued in
denominations of $1,000,000 and $1,000 increments above $1,000,000 of the
Initial Class B-1 Note Principal Balance, the Initial Class B-2 Note Principal
Balance and the Initial Class B-3 Note Principal Balance. Each Note shall
represent a validly issued and binding obligation, 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, Class A-2 Notes, Class A-3 Notes and Class A-4
Notes shall be substantially in the forms set forth in Exhibits C-1, C-2, C-3
and C-4 hereto, respectively, all Class B-1 Notes shall be substantially in the
form set forth in Exhibit D-1 hereto, all Class B-2 Notes shall be substantially
in the form set forth in Exhibit D-2 hereto, all Class B-3 Notes shall be
substantially in the form set forth in Exhibit D-3 hereto. Each Note shall be
dated the date of their authentication. Neither the Notes nor the Contracts are
insured by the Federal Deposit Insurance Corporation or any other governmental
agency.

         (b) It is intended that the Offered Notes be registered so as to
participate in a global book-entry system with the Trust, as set forth herein.
The Offered 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, Class A-3 Note and Class A-4 Note, each with a denomination equal to
the Initial Class A-1 Note Principal Balance, the Initial Class A-2 Note
Principal Balance, the Initial Class A-3 Note Principal Balance and the Initial
Class A-4 Note Principal Balance, respectively. Upon initial issuance, the
ownership of each such Offered Note shall be registered in the Register in the
name of Cede & Co., or any successor thereto, as nominee for the Trustee.



                                       17
<PAGE>   24

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

         With respect to Offered 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 Offered 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 Offered 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 Offered 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 Offered Notes. No
Person other than a Noteholder shall receive a certificate evidencing such
Offered 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 Offered 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 Offered 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 Offered 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 Offered Notes may be registered in whatever name or names Noteholders
transferring Offered Notes shall designate, in accordance with the provisions
hereof; provided, however, that any such registration shall be at the expense of
the Servicer.

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



                                       18
<PAGE>   25

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.

         (e) No transfer of any Subordinate Note shall be made unless such
transfer is made in a transaction which does not require registration or
qualification under the Securities Act or qualification under any state
securities or "Blue Sky" laws. If such a transfer is to be made in reliance upon
an exemption from the Securities Act other than Rule 144A thereunder, (A) the
Indenture Trustee shall receive an Opinion of Counsel that such transfer may be
made pursuant to an exemption from the Securities Act, describing the applicable
exemption and the basis therefor, which Opinion of Counsel shall not be an
expense of First Sierra, the Depositor, the Servicer, the Trust or the Indenture
Trustee or (B) the Indenture Trustee shall require the transferee to execute a
certification, substantially in the form of Exhibit F hereto, setting forth the
facts surrounding such transfer. In the event that a transfer is to be made in
reliance on Rule 144A under the Securities Act, the Subordinate Noteholder shall
cause its prospective transferee to execute and deliver a certificate
substantially in the form of Exhibit G hereto; provided, however, that with
respect to any sale of a Subordinate Note by an investment company registered
under the Investment Company Act of 1940, as amended, made in reliance on Rule
144A, the Subordinate Noteholder may (in lieu of delivering a certificate in the
form of Exhibit G) deliver to the Indenture Trustee a certificate in the form of
Exhibit H hereto with a copy of a Qualified Institutional Buyer Certificate in
the form of Addendum 1 thereto. The Servicer promptly shall furnish to any
Holder, or any prospective purchaser designated by a Holder, the information
required to be delivered to Holders and prospective purchasers of Subordinate
Notes in connection with the resale of the Subordinate Notes to permit
compliance with Rule 144A in connection with such resale. No Subordinate Note
may be subdivided for resale or other transfer into a unit smaller than a unit
the initial offering price of which would have been in the aggregate $1,000,000.
No resale or other transfer of the Subordinate Notes may be made to a
nonresident alien individual, foreign corporation or other non-United States
person.

         (f) Notwithstanding anything else contained in this Indenture, neither
the Indenture Trustee nor the Note Registrar shall effect the registration of
any transfer of a Subordinate Note (i) unless, prior to such transfer, the
Indenture Trustee shall have received from the Subordinate Noteholder (with a
copy to each Rating Agency) an Opinion of Counsel to the effect that such
transfer will not result in the Trust becoming subject to taxation as an
association taxable as a corporation or (ii) if following such transfer the sum
of (a) the number of Holders of a Subordinate Note and (b) the number of Holders
of the Trust Certificate, would be more than 99. Ownership of the Trust
Certificate shall be nontransferable, but may be pledged to secure non-recourse
debt of the Depositor.

         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 Subordinate Notes executed by
the Trust in authorized denominations equaling in the aggregate the Initial
Class A Note Principal Balance, the Initial Class B-1 Note 



                                       19
<PAGE>   26

Principal Balance, the Initial Class B-2 Note Principal Balance and the Initial
Class B-3 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, subject to the requirements of Sections 5.01(e) and
(f) hereof in the case of the Subordinate Notes, 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, Class A-3 Percentage Interest, Class A-4 Percentage
Interest, Class B-1 Percentage Interest, Class B-2 Percentage Interest or Class
B-3 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 Subordinate Notes) of a like aggregate Class A-1 Percentage Interest,
Class A-2 Percentage Interest, Class A-3 Percentage Interest, Class A-4
Percentage Interest, Class B-1 Percentage Interest, Class B-2 Percentage
Interest or Class B-3 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. Every Note presented or surrendered for registration of
transfer or exchange shall be accompanied by a written instrument of transfer
substantially in the form of Exhibit H hereto, duly executed by the Noteholder
thereof or its attorney duly authorized in writing.

         (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 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 an Offered 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 



                                       20
<PAGE>   27

Plan, or (ii) with respect to the transfer of any Note other than a Class B-3
Note, that the transferee's acquisition and continued holding of the Note will
be covered by a U.S. Department of Labor Prohibited Transaction Class Exemption.
Each transferee of a beneficial interest in an Offered 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 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 (provided, that with respect to a
Subordinate Noteholder which is an insurance company whose long-term debt or
claims paying ability is rated investment grade or better by the Rating Agencies
at such time, a letter of indemnity furnished by it shall be sufficient for this
purpose), 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 and the Note
Insurer 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 3.04
hereof and for all other purposes whatsoever, and the Note Insurer 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, a Class B-1 Percentage Interest, a Class B-2 Percentage
Interest or a Class B-3 Percentage Interest of not 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 Servicer
and the Indenture Trustee that none of the Trust, 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.

                                       21
<PAGE>   28

         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, the Note Insurer 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, First Sierra
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 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 Residual 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 Owner Trustee shall be under any liability to the Indenture Trustee, the
Noteholders, First Sierra, the Servicer, the Residual 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, First Sierra, the Servicer,
the Residual Holder or any other Person for any action taken or for refraining

<PAGE>   29

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

good faith on any document of any kind prima facie properly executed and
submitted by any other Person respecting any matters arising hereunder.

behalf of the Trust shall be deemed to have agreed to indemnify, defend and hold

its directors, employees, officers and agents), the Noteholders and the Note
Insurer 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 Residual Holder
pursuant to Section 3.04(b)(xviii) hereof.

         Section 6.04 Liabilities. Notwithstanding any provision of this
Indenture, by entering into this Indenture, the Trust and the Residual Holder

B-3 Noteholder in the capacity of an investor in the Class A Notes, the Class
B-1 Notes, the Class B-2 Notes or the Class B-3 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

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 and the Note Insurer, within
90 days after the end of each fiscal year of the Trust (commencing 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

                  (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 Trust will duly and
punctually pay the principal of and interest on the Notes in accordance with the
terms of the 



                                       23
<PAGE>   30

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 Trust will 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 Trust
hereby initially appoints the Indenture Trustee to serve as its agent for the
foregoing purposes. The Trust will give prompt written notice to the Indenture
Trustee of the location, and of any change in the location, of any such office
or agency. If at any time the Trust shall fail to maintain any such office or
agency or shall fail to furnish the Indenture Trustee with the address thereof,
such surrenders, notices and demands may be made or served at the Corporate
Trust Office, and the Trust hereby appoints the Indenture Trustee as its agent
to receive all such surrenders, notices and demands.

         Section 6.09 Money for Payments to be Held in Trust. On or before each
Payment Date, 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 Trust will cause each paying agent other than the Indenture Trustee
to execute and deliver to the Indenture Trustee and the Note Insurer 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

                  (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 



                                       24
<PAGE>   31

         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 with the written consent and direction of the Note
Insurer 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, if such money or any portion thereof had been
previously deposited by the Note Insurer with the Indenture Trustee for the
payment of principal or interest on the Notes, to the extent any amounts are
owing to the Note Insurer, such amounts shall be paid promptly to the Note
Insurer upon receipt of a written request by the Note Insurer to such effect;
and provided, further, 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.

         Section 6.11 Protection of Trust Property. The Trust intends the
security interest granted pursuant to this Indenture in favor of the Indenture
Trustee, the Note Insurer and the Noteholders, as their interests appear herein,
to be prior to all other liens in respect of the Trust Property, and the Trust
shall take all actions necessary to obtain and maintain, in favor of the
Indenture Trustee, for the benefit of the Noteholders and the Note Insurer, a
first lien on and a first priority, perfected security interest in the Trust
Property. 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 Trust
         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 and the Note Insurer, 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 Trust Property and the
         rights of the Indenture Trustee in such Trust Property against the
         claims of all persons and parties; and

                  (vi) pay all taxes or assessments levied or assessed upon the
         Trust 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 or the Note Insurer 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 Trust 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 acceptable to the Note
Insurer to assist it in performing its duties under this Indenture, and any
performance of such duties by a Person identified to the Indenture Trustee and
the Note Insurer 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 



                                       26
<PAGE>   33

Trust may rely upon information provided by 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 Trust 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, the
Note Insurer 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 a Servicer Termination Event 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
         Transaction Documents, sell, transfer, exchange or otherwise dispose of
         any of the properties or assets of the Trust, including those included
         in the Trust Property, unless directed to do so by the Note Insurer;

                  (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 Trust
         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 Trust 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), (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 Trust Property or (D) amend, modify or fail to comply
         with the provisions of the Transaction Documents without the prior
         written consent of the Note Insurer;

         Section 6.19 Capital Expenditures. The Trust shall not make any
expenditure (by long-term or operating lease or otherwise) for capital assets
(either realty or personal).

         Section 6.20 Compliance with Laws. The Trust shall comply with the
requirements of all applicable laws, the non-compliance with which would,
individually or in the aggregate, materially and adversely affect the ability of
the Trust to perform its obligations under the Notes, this Indenture or any
other Transaction Document.

         Section 6.21 Further Instruments and Acts. Upon request of the
Indenture Trustee or the Note Insurer, the Trust will execute and deliver such
further instruments and do such further acts as may be reasonably necessary or
proper to carry out more effectively the purpose of this Indenture and the other
Transaction Documents.


                                  ARTICLE VII.

                              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



                                       30
<PAGE>   37

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; 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%, 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, any Event of Default or
         Restricting Event 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, the Note Insurer 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 



                                       31
<PAGE>   38

         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 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 and the Note
Insurer if the total amount then on deposit in the Collection Account is less
than the amount indicated in the Monthly Statement.

         (f) The Indenture Trustee shall promptly notify the Note Insurer upon
obtaining actual knowledge or receipt of written notice by a Responsible Officer
of the Indenture Trustee of: (a) any proposed change herein or supplement
hereto; (b) the occurrence of any Event of Default, Event of Servicing
Termination or Restricting Event actually known to a Responsible Officer of the
Indenture Trustee; (c) any proposed change of the Indenture Trustee hereunder;
(d) any matter to be put to the Noteholders for election hereunder; (e) any
proposed exercise by the Noteholders of any option, vote, right, power or the
like hereunder; and (f) any other matter, notice of which is required hereunder
to be given to any of the Noteholders or to the Indenture Trustee.

         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 the Note Insurer and (ii) executing 



                                       32
<PAGE>   39

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 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 Note Insurer or 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 



                                       33
<PAGE>   40

         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 First Sierra, 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 and the Note Insurance Policy 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 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 First Sierra 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 First Sierra 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.



                                       34
<PAGE>   41

         Section 7.06 Indenture Trustee May Own Notes. The Indenture Trustee in
its individual or any other capacity may become the owner or pledge 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 Residual Holder agrees:

                  (i) to pay to the Indenture Trustee, pursuant to Section
         3.04(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); provided, however, that to the
         extent payment of any such Indenture Trustee Fees from the Collection
         Account would result in an Available Funds Shortfall, such Indenture
         Trustee Fees in an amount equal to the amount of the Available Funds
         Shortfall shall instead be paid directly by First Sierra to the
         Indenture Trustee;

                  (ii) except to the extent otherwise expressly provided herein,
         to reimburse the Indenture Trustee, pursuant to Section 3.04(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 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; provided, further, however, that to the extent
         payment of any such Indenture Trustee Expenses from the Collection
         Account would result in an Available Funds Shortfall, such Indenture
         Trustee Expenses in an amount equal to the amount of the Available
         Funds Shortfall shall instead be paid directly by First Sierra to the
         Indenture Trustee; and

                  (iii) to reimburse the Indenture Trustee, pursuant to Section
         3.04(b)(xvi), 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 



                                       35
<PAGE>   42

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 ss. 310(a).
The Indenture Trustee hereunder shall at all times be a corporation acceptable
to the Note Insurer 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 Offered Notes or the Subordinate
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 7.09 hereof. The Indenture
Trustee shall comply with TIA ss. 310(b), including the optional provision
permitted by the second sentence of TIA ss. 310(b)(9); provided, however, that
there shall be excluded from the operation of TIA ss. 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 ss. 310(b)(1) are met.

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



                                       36
<PAGE>   43

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 may, with the
consent of the Note Insurer, and shall, at the direction of (i) the Note Insurer
or (ii) the Holders of Notes of any Class evidencing Percentage Interests of
more than 25% of the related Class, with the consent of the Note Insurer, remove
the Indenture Trustee. Notwithstanding anything in this Indenture to the
contrary, the Note Insurer shall have the right to remove the Indenture Trustee
for "cause." For purposes of this section, "cause" shall mean (i) the gross
negligence or willful misconduct of the Indenture Trustee in the performance of
its duties under this Indenture or the Insurance Agreement or (ii) the failure
or unwillingness of the Indenture Trustee to perform its duties under this
Indenture or the Insurance Agreement; provided, however, the Note Insurer may
not remove the Indenture Trustee for "cause" pursuant to clause (ii) of the
immediately preceding sentence unless it has (A) consulted with the Indenture
Trustee in good faith and provided notice to the Indenture Trustee regarding any
actions or omissions of the Indenture Trustee under this Indenture or the
Insurance Agreement which the Note Insurer believes constitutes a failure or
unwillingness of the Indenture Trustee to perform its duties under this
Indenture or the Insurance Agreement and (B) provided the Indenture Trustee with
the opportunity to remedy such failure or unwillingness within 10 Business Days
(or such longer period to which the Note Insurer may reasonably consent)
following the receipt by the Indenture Trustee of written notice thereof. In the
event that the Indenture Trustee is removed by the Note Insurer pursuant to this
Section, the removal and substitution procedures set forth in this Section 7.10
and Section 7.11 hereof shall be followed. If the Servicer, the Note Insurer or
Noteholders remove the Indenture Trustee, the Servicer, the Note Insurer or such
Noteholders shall promptly appoint a successor Indenture Trustee acceptable to
the Note Insurer 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, the Note Insurer 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 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 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 



                                       37
<PAGE>   44

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 acceptable to the Note Insurer and 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 the Note Insurer and 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, with the consent of, or at the written direction of,
the Note Insurer, 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, and the Note Insurer 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; provided, however, that if there is
a conflict between the Trust, the Indenture Trustee and the Note Insurer
regarding the appointment of a co-Indenture Trustee or separate Indenture
Trustee, the Note Insurer shall prevail. 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 and Trust, acting jointly, 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

                                       38
<PAGE>   45

appointment of any co-Indenture Trustee or separate Indenture Trustee shall be
required under Section 7.12 hereof.

         (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 Trust 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.



                                       39
<PAGE>   46

         (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 and the Note Insurer 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, the Noteholders and the Note Insurer.

         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 or the Note Insurer, 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 and
the Note Insurer 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 



                                       40
<PAGE>   47

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

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 monthly Payment Date when such amount is due and payable; and

         (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 Maturity Date, the
Class A-3 Maturity Date, the Class A-4 Maturity Date, the Class B-1 Maturity



                                       41

         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 Controlling Parties, shall
declare the principal of all of the Notes to be immediately due and payable, by

principal (together with all accrued and previously unpaid interest) shall
become immediately due and payable. The Indenture Trustee shall give notice to
each Noteholder, the Note Insurer 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 Controlling Parties, 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 Subordinate Notes;

                  (ii) the principal of any of the Class A Notes or the
         Subordinate 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,

         the Subordinate 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, or the Note Insurer hereunder or

         reasonable compensation, expenses, disbursements and advances of the
         Indenture Trustee, the Note Insurer and their respective 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 has 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 and the
Note Insurer ten days notice of its intention to take such actions.

         Section 8.03 Remedies. (a) If an Event of Default shall have occurred

         (c) 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;

         (d) 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

         (e) 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, the Note Insurer or the
Noteholders hereunder.

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, the Note Insurer
(including, in each case, any claim for the reasonable compensation, expenses,
disbursements and advances of the Indenture Trustee, the Note Insurer, and their
respective 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



                                       43
<PAGE>   50

         (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 payments directly to
the Note Insurer or 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 the Note Insurer or any
Noteholder any plan of reorganization, arrangement, adjustment or composition
affecting, the Note Insurer, the Notes or the rights of any Holder thereof, or
to authorize the Indenture Trustee to vote in respect of the claim of the Note
Insurer or any Noteholder in any such Proceeding.

         Section 8.07 Allocation of Money Collected. If the Notes have been
declared due and payable following an Event of Default and such declaration and
its consequences have not been rescinded and annulled, any money collected by
the Indenture Trustee with respect to the Notes pursuant to this Article (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

the prior written consent of the Note Insurer) may, by one or more instruments
in writing, waive any Event of Default hereunder and its consequences, except a
continuing Event of Default:

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,

Trustee of a continuing Event of Default;

         (b) the Controlling Parties shall have made written request to the

this Indenture to affect, disturb or prejudice the rights of any other Holders
or the Note Insurer or to enforce any right under this Indenture, except in the
manner herein provided.

Noteholder, then and in every such case, the Indenture Trustee, the Note Insurer
and the Noteholders shall, subject to any determination in such Proceeding, be
restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies hereunder shall continue as though no such
Proceeding has been instituted.

         Section 8.12 Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Indenture Trustee, the Note Insurer 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, the Note Insurer 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,
the Note Insurer 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, the 



                                       46

Note Insurer or the Noteholders, subject however to the right of the Note
Insurer to control any such right and remedy.

shall have the right to direct in writing the decision whether to conduct, and
the time, method and place of conducting, any Proceeding for any remedy
available to the Indenture Trustee with respect to the Notes or exercising any
trust or power conferred on the Indenture Trustee with respect to the Notes;
provided, that:

         (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
unimpaired until the entire Pledged Property securing the Notes shall have been
sold or all amounts payable under this Indenture with respect thereto shall have
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. To the extent
permitted by law, the Indenture Trustee shall not sell the Pledged Property
without the prior written consent of the Note Insurer.

ten days after notice thereof is commercially reasonable.

         (d) The Indenture Trustee shall execute and deliver an appropriate
instrument of conveyance, provided to it by the Servicer, transferring its
interest in any portion of the Pledged Property in connection with a sale
thereof. In addition, the Indenture Trustee is hereby irrevocably appointed the
agent and attorney-in-fact of the Trust to transfer and convey its interest in
any portion of the Pledged Property in connection with a sale thereof, and to
take all action necessary to effect such sale. No purchaser or transferee at
such a sale shall be bound to ascertain the Indenture Trustee's authority,
inquire into the satisfaction of any conditions precedent or see to the
application of any monies.

         Section 8.16 Action on Notes. The Indenture Trustee's right to seek and
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 



                                       47

Depositor or by the levy of any execution under such judgment upon any portion

in writing by no later than two (2) Business Days prior to a notice required to

upon which final payment of the Notes will be made, (ii) the scheduled amount of
any such final payment, (iii) that interest shall cease to accrue on the Class A
Notes and the Subordinate Notes on such final Payment Date and (iv) the address
for presentation of the Notes for final payment. On such final Payment Date, the
Indenture Trustee shall cause to be distributed the amounts otherwise
distributable on such Payment Date pursuant to Section 3.04 hereof, taking into
account the purchase pursuant to Section 9.02(a). After such Payment Date,
interest on the Class A and Subordinate Notes shall cease to accrue.

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.

extent not otherwise defined herein, the capitalized terms used herein have the
meanings assigned to them in the Indenture.

                  This Class A-1 Note is one of the duly authorized Class A-1
Notes designated as "5.215% Equipment Contract Backed Notes of First Sierra
Equipment Contract Trust 1998-1, Class A-1" (the "Class A-1 Notes"). This Class
A-1 Note is issued under and is subject to the terms, provisions and conditions
of the Indenture, to which Indenture the Holder of this Class A-1 Note, by
virtue of the acceptance hereof, assents and by which such Holder is bound.

                  This Class A-1 Note does not purport to summarize the
Indenture and reference is made to the Indenture for information with respect to
the interests, rights, benefits, obligations, proceeds and duties evidenced
hereby and the rights, duties and immunities of the Issuer. Copies of the
Indenture and all amendments thereto will be provided to any Class A-1
Noteholder, at its expense, upon a written request to the Servicer: 600 Travis

such Person in accordance with the terms of the Indenture or by such other means
as the Person entitled thereto and the Indenture Trustee shall agree, without
the presentation or surrender of this Class A-1 Note or the making of any
notation hereon.

                  The Holder hereof, by its acceptance of this Class A-1 Note,
agrees to look solely to the funds in the Collection Account to the extent
available for payment to the Holder hereof as provided in the Indenture for
payment hereunder and that the Indenture Trustee in its individual capacity is

A-1 Note or the Indenture. In addition, the Holder hereof, by its acceptance of
this Note, agrees to treat such Note as indebtedness of the Issuer and hereby

interest in, First Union Trust Company, National Association, First Sierra or
any Affiliate thereof. The Class A-1 Notes are limited in right of payment to
certain collections and recoveries respecting the Contracts, all as more

PAYMENT IN FULL OF ALL AMOUNTS OF PRINCIPAL AND INTEREST DUE AND PAYABLE ON THE
CLASS A NOTES ON EACH PAYMENT DATE.

                  The Indenture permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the Servicer and the rights of the Class A-1
Noteholders under the Indenture at any time by the Servicer, the Issuer and the
Indenture Trustee with the consent of the Majority Holders and the Note Insurer.
Any such consent by the Holder of this Class A-1 Note shall be conclusive and
binding on such Holder and upon all future Holders of this Class A-1 Note and of
any Class A-1 Note issued upon the transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent is made upon this Class A-1
Note. The Indenture also permits the amendment thereof, in certain limited
circumstances, without the consent of the Class A-1 Noteholders.

                  By its acceptance of this Class A-1 Note, each Holder shall be
deemed to have agreed that such Holder will not directly or indirectly
institute, or cause to be instituted, against the Residual 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.

                  As provided in the Indenture, the transfer of this Class A-1
Note is registrable in the Register upon surrender of this Class A-1 Note for
registration of transfer at the offices or agencies maintained by the Indenture
Trustee accompanied by a written instrument of transfer in form satisfactory to
the Indenture Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Class A-1
Notes of authorized denominations evidencing the same aggregate Class A-1
Percentage Interest in the Trust Property will be issued to the designated
transferee or transferees.

                  Each transferee of a beneficial interest in this Class A-1
Note shall be deemed to represent either (i) that it is not (A) an employee
benefit plan (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("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 Internal
Revenue Code of 1986, as amended (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 its
acquisition and continued holding of this Class A-1 Note will be covered by a
U.S. Department of Labor Prohibited Transaction Class Exemption.

                  The Class A-1 Notes are issuable only as registered Class A-1
Notes without coupons in minimum denominations of $1,000 of the Initial Class
A-1 Note Principal Amount. As provided in the Indenture and subject to certain
limitations therein set forth, Class A-1 Notes are exchangeable for new Class
A-1 Notes of authorized denominations evidencing the same aggregate Class A-1
Percentage Interest, as requested by the Class A-1 Noteholder surrendering the
same.

                  Unless earlier declared, or they otherwise become, due and
payable by reason of an Event of Default, the Notes are payable only at the time
and in the manner provided in the Indenture and are not redeemable or prepayable
before such time except that the Residual Holder will have the option, subject
to certain conditions set forth in the Indenture, including the deposit of the
sum specified in the Indenture, to cause early retirement of the Notes as of any
Payment Date following the date on which the aggregate Class A Note Principal
Balance and the Subordinate Note Principal Balance is less than 10% of the
Initial Class A Note Principal Amount and the Initial Subordinate Note Principal
Amount. In the event of such redemption, the entire outstanding Class A Note
Principal Balance and the Subordinate Note Principal Balance, together with
accrued interest thereon at the related Note Rate, will be required to be paid
to the respective Class A Noteholders and the respective Subordinate Noteholders
on such Payment Date. If an Event of Default as defined in the Indenture shall
occur and be continuing, the principal of all the Notes may become or be
declared due and payable in the manner and with the effect provided in the
Indenture.

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

                  The Servicer, the Issuer and the Indenture Trustee and any
agent of any of the foregoing may treat the person in whose name this Class A-1
Note is registered as the owner hereof for all purposes, and none of the
foregoing shall be affected by any notice to the contrary.

funds are properly applied by the Trustee. Insured Payments shall be made only
at the time set forth in the Policy, and no accelerated Insured Payments shall
be made regardless of any acceleration of the Class A-1 Notes, unless such
acceleration is at the sole option of the Insurer.

                  Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Trust or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                  The Insurer will pay any Insured Payment that is a Preference
Amount (as described below) on the Business Day following receipt on a Business
Day by the Fiscal Agent (as described below) of (i) a certified copy of the
order requiring the return of a preference payment, (ii) an opinion of counsel
satisfactory to the Insurer that such order is final and not subject to appeal,
(iii) an assignment in such form as is reasonably required by the Insurer,
irrevocably assigning to the Insurer all rights and claims of the Owner relating
to or arising under the Class A-1 Notes against the debtor which made such
preference payment or otherwise with respect to such preference payment and (iv)
appropriate instruments to effect the appointment of the Insurer as agent for
such Owner in any legal proceeding related to such preference payment, such
instruments being in a form satisfactory to the Insurer, provided that if such
documents are received after 12:00 noon, New York City time on such Business
Day, they will be deemed to be received on the following Business Day. Such
payments shall be disbursed to the receiver or trustee in bankruptcy named in
the final order of the court exercising jurisdiction on behalf of the Owner and
not to any Owner directly unless such Owner has returned principal or interest
paid on the Class A-1 Notes to such receiver or trustee in bankruptcy, in which
case such payment shall be disbursed to such Owner.

                  The Insurer will pay any other amount payable under the Policy
no later than 12:00 noon, New York City time, on the later of the Payment Date
on which the related Deficiency Amount is due or the second Business Day
following receipt in New York, New York on a Business Day by State Street Bank
and Trust Company, N.A., as Fiscal Agent for the Insurer or any successor fiscal
agent appointed by the Insurer (the "Fiscal Agent") of a Notice (as described
below); provided that if such Notice is received after 12:00 noon, New York City
time, on such Business Day, it will be deemed to be received on the following
Business Day. If any such Notice received by the Fiscal Agent is not in proper
form or is otherwise insufficient for the purpose of making claim under the
Policy, it shall be deemed not to have been received by the Fiscal Agent for
purposes of this paragraph, and the Insurer or the Fiscal Agent, as the case may
be, shall promptly so advise the Trustee and the Trustee may submit an amended
Notice.

                  Insured Payments due under the Policy, unless otherwise stated
in the Policy, will be disbursed by the Fiscal Agent to the Trustee on behalf of
the Owners by wire transfer of immediately available funds in the amount of the
Insured Payment less, in respect of Insured Payments related to Preference
Amounts, any amount held by the Trustee for the payment of such Insured Payment
and legally available therefor.

"Servicer" and "Originator") and Bankers Trust Company, as Indenture Trustee
(the "Indenture Trustee"), at all times from the sources and on the terms and
conditions hereinafter set forth and as more fully set forth in the Indenture.

                  The property pledged by the Owner Trustee, on behalf of the
Issuer, to the Indenture Trustee as security for the Class A-2 Notes includes
the Contracts, the Equipment, all Scheduled Payments, Final Scheduled Payments,

extent not otherwise defined herein, the capitalized terms used herein have the
meanings assigned to them in the Indenture.

                  This Class A-2 Note is one of the duly authorized Class A-2
Notes designated as "5.490% Equipment Contract Backed Notes of First Sierra
Equipment Contract Trust 1998-1, Class A-2" (the "Class A-2 Notes"). This Class
A-2 Note is issued under and is subject to the terms, provisions and conditions
of the Indenture, to which Indenture the Holder of this Class A-2 Note, by
virtue of the acceptance hereof, assents and by which such Holder is bound.

                  This Class A-2 Note does not purport to summarize the
Indenture and reference is made to the Indenture for information with respect to
the interests, rights, benefits, obligations, proceeds and duties evidenced
hereby and the rights, duties and immunities of the Issuer. Copies of the
Indenture and all amendments thereto will be provided to any Class A-2
Noteholder, at its expense, upon a written request to the Servicer: 600 Travis
Street, Suite 7050, Houston, Texas 77002; Attention: Sandy Ho, Chief Financial
Officer.

                  Under the Indenture, the Issuer is obligated to cause the
Indenture Trustee to pay, to the extent that monies are available in the
Collection Account for such distributions, on the 12th day of each Payment Date,

specified in the Register at the close of business on the Record Date, an amount

and (ii) the Class A Base Principal Distribution Amount. The final payment of
principal and interest on this Class A-2 Note will not be later than the April,
2001 Payment Date.

                  Payments on this Class A-2 Note will be made by the Indenture
Trustee by check mailed, or upon request of the Holder hereof, by wire transfer
of immediately available funds, to the Person entitled thereto, as specified by
such Person in accordance with the terms of the Indenture or by such other means
as the Person entitled thereto and the Indenture Trustee shall agree, without
the presentation or surrender of this Class A-2 Note or the making of any
notation hereon.

                  The Holder hereof, by its acceptance of this Class A-2 Note,
agrees to look solely to the funds in the Collection Account to the extent
available for payment to the Holder hereof as provided in the Indenture for
payment hereunder and that the Indenture Trustee in its individual capacity is
not personally liable to the Holder hereof for any amounts due under this Class
A-2 Note or the Indenture. In addition, the Holder hereof, by its acceptance of
this Note, agrees to treat such Note as indebtedness of the Issuer and hereby
instructs the Indenture Trustee to treat such Note as indebtedness of the Issuer
for purposes of Federal, state and local income and franchise and any other
income taxes.

                  The Class A-2 Notes do not represent an obligation of, or an
interest in, First Union Trust Company, National Association, First Sierra or
any Affiliate thereof. The Class A-2 Notes are limited in right of payment to
certain collections and recoveries respecting the Contracts, all as more
specifically set forth above in the Indenture. Pursuant to the Indenture, the
Indenture Trustee shall, in addition to the Class A-2 Notes, issue Class A-1
Notes, Class A-3 Notes and Class A-4 Notes (together with the Class A-2 Notes,
the "Class A Notes or the "Offered Notes") and Class B-1 Notes, B-2 Notes and
Class B-3 Notes (collectively the Subordinate Notes") and pursuant to the Trust
Agreement, the Owner Trustee shall issue the Trust Certificate. THE RIGHT TO
RECEIVE PAYMENTS OF INTEREST WITH RESPECT TO EACH CLASS OF CLASS A NOTES IS PARI
PASSU WITH EACH OTHER CLASS OF CLASS A NOTES AND THE RIGHT TO RECEIVE PAYMENTS
OF PRINCIPAL WITH RESPECT TO EACH CLASS OF CLASS A NOTES IS ON A SEQUENTIAL-PAY

BASIS WHEREBY PRINCIPAL IS APPLIED TO REDUCE THE NOTE PRINCIPAL BALANCE OF THE
CLASS A NOTES THEN OUTSTANDING AND HAVING THE LOWEST NUMERICAL DESIGNATION
(E.G., FIRST TO THE CLASS A-1 NOTES) TO ZERO BEFORE ANY PRINCIPAL PAYMENT IS
MADE TO THE NEXT CLASS. THE RIGHT TO RECEIVE PAYMENTS WITH RESPECT TO THE
SUBORDINATE NOTES AND THE TRUST CERTIFICATE IS SUBORDINATE TO THE PRIOR PAYMENT
IN FULL OF ALL AMOUNTS OF PRINCIPAL AND INTEREST DUE AND PAYABLE ON THE CLASS A
NOTES ON EACH PAYMENT DATE.

                  The Indenture permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the Servicer and the rights of the Class A-2
Noteholders under the Indenture at any time by the Servicer, the Issuer and the
Indenture Trustee with the consent of the Majority Holders and the Note Insurer.
Any such consent by the Holder of this Class A-2 Note shall be conclusive and
binding on such Holder and upon all future Holders of this Class A-2 Note and of
any Class A-2 Note issued upon the transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent is made upon this Class A-2
Note. The Indenture also permits the amendment thereof, in certain limited
circumstances, without the consent of the Class A-2 Noteholders.

                  By its acceptance of this Class A-2 Note, each Holder shall be
deemed to have agreed that such Holder will not directly or indirectly
institute, or cause to be instituted, against the Residual 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.

                  As provided in the Indenture, the transfer of this Class A-2
Note is registrable in the Register upon surrender of this Class A-2 Note for
registration of transfer at the offices or agencies maintained by the Indenture
Trustee accompanied by a written instrument of transfer in form satisfactory to
the Indenture Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Class A-2
Notes of authorized denominations evidencing the same aggregate Class A-2
Percentage Interest in the Trust Property will be issued to the designated
transferee or transferees.

                  Each transferee of a beneficial interest in this Class A-2
Note shall be deemed to represent either (i) that it is not (A) an employee
benefit plan (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("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 Internal
Revenue Code of 1986, as amended (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 its
acquisition and continued holding of this Class A-2 Note will be covered by a
U.S. Department of Labor Prohibited Transaction Class Exemption.

                  The Class A-2 Notes are issuable only as registered Class A-2
Notes without coupons in minimum denominations of $1,000 of the Initial Class
A-2 Note Principal Amount. As provided in the Indenture and subject to certain
limitations therein set forth, Class A-2 Notes are exchangeable for new Class
A-2 Notes of authorized denominations evidencing the same aggregate Class A-2
Percentage Interest, as requested by the Class A-2 Noteholder surrendering the
same.

                  Unless earlier declared, or they otherwise become, due and
payable by reason of an Event of Default, the Notes are payable only at the time
and in the manner provided in the Indenture and are not redeemable or prepayable
before such time except that the Residual Holder will have the option, subject
to certain conditions set forth in the Indenture, including the deposit of the
sum specified in the Indenture, to cause early retirement of the Notes as of any
Payment Date following the date on which the aggregate Class A Note Principal
Balance and the Subordinate Note Principal Balance is less than 10% of the
Initial Class A Note Principal Amount and the Initial Subordinate Note Principal
Amount. In the event of such redemption, the entire outstanding Class A Note
Principal Balance and the Subordinate Note Principal Balance, together with
accrued interest thereon at the related Note Rate, will be required to be paid
to the respective Class A Noteholders and the respective Subordinate Noteholders
on such Payment Date. If an Event of Default as defined in the Indenture shall
occur and be continuing, the principal of all the Notes may become or be
declared due and payable in the manner and with the effect provided in the
Indenture.

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

                  The Servicer, the Issuer and the Indenture Trustee and any
agent of any of the foregoing may treat the person in whose name this Class A-2
Note is registered as the owner hereof for all purposes, and none of the
foregoing shall be affected by any notice to the contrary.

                        Class A-2 Notes, 5.490% Interest Rate

                  MBIA Insurance Corporation (the "Insurer") has issued a Note
Guaranty Insurance Policy (the "Policy") relating to the Class A-2 Notes
containing the following provisions, the Policy being on file at the Corporate
Trust Office of the Trustee (as defined herein).

                  The Insurer, in consideration of the payment of the premium
and subject to the terms of this Policy, hereby unconditionally and irrevocably
guarantees to any Owner that an amount equal to each full and complete Insured
Payment will be received by Bankers Trust Company, or its successor, as trustee
for the Owners (the "Trustee"), on behalf of the Owners from the Insurer, for
distribution by the Trustee to each Owner of each Owner's proportionate share of
the Insured Payment. The Insurer's obligations under the Policy with respect to
a particular Insured Payment shall be discharged to the extent funds equal to
the applicable Insured Payment are received by the Trustee, whether or not such
funds are properly applied by the Trustee. Insured Payments shall be made only
at the time set forth in the Policy, and no accelerated Insured Payments shall
be made regardless of any acceleration of the Class A-2 Notes, unless such
acceleration is at the sole option of the Insurer.

                  Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Trust or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                  The Insurer will pay any Insured Payment that is a Preference
Amount (as described below) on the Business Day following receipt on a Business
Day by the Fiscal Agent (as described below) of (i) a certified copy of the
order requiring the return of a preference payment, (ii) an opinion of counsel
satisfactory to the Insurer that such order is final and not subject to appeal,
(iii) an assignment in such form as is reasonably required by the Insurer,
irrevocably assigning to the Insurer all rights and claims of the Owner relating
to or arising under the Class A-2 Notes against the debtor which made such
preference payment or otherwise with respect to such preference payment and (iv)
appropriate instruments to effect the appointment of the Insurer as agent for
such Owner in any legal proceeding related to such preference payment, such
instruments being in a form satisfactory to the Insurer, provided that if such

time, on such Business Day, it will be deemed to be received on the following

Issuer, to the Indenture Trustee as security for the Class A-3 Notes includes
the Contracts, the Equipment, all Scheduled Payments, Final Scheduled Payments,

extent not otherwise defined herein, the capitalized terms used herein have the
meanings assigned to them in the Indenture.

                  This Class A-3 Note is one of the duly authorized Class A-3
Notes designated as "5.450% Equipment Contract Backed Notes of First Sierra
Equipment Contract Trust 1998-1, Class A-3" (the "Class A-3 Notes"). This Class
A-3 Note is issued under and is subject to the terms, provisions and conditions
of the Indenture, to which Indenture the Holder of this Class A-3 Note, by
virtue of the acceptance hereof, assents and by which such Holder is bound.

                  This Class A-3 Note does not purport to summarize the
Indenture and reference is made to the Indenture for information with respect to
the interests, rights, benefits, obligations, proceeds and duties evidenced
hereby and the rights, duties and immunities of the Issuer. Copies of the
Indenture and all amendments thereto will be provided to any Class A-3
Noteholder, at its expense, upon a written request to the Servicer: 600 Travis
Street, Suite 7050, Houston, Texas 77002; Attention: Sandy Ho, Chief Financial
Officer.

                  Under the Indenture, the Issuer is obligated to cause the
Indenture Trustee to pay, to the extent that monies are available in the
Collection Account for such distributions, on the 12th day of each Payment Date,
to the person in whose name this Class A-3 Note is registered and at the address
specified in the Register at the close of business on the Record Date, an amount
from certain monies deposited in the Collection Account with respect to the

and (ii) the Class A Base Principal Distribution Amount. The final payment of
principal and interest on this Class A-3 Note will not be later than the
February, 2002 Payment Date.

                  Payments on this Class A-3 Note will be made by the Indenture
Trustee by check mailed, or upon request of the Holder hereof, by wire transfer
of immediately available funds, to the Person entitled thereto, as specified by
such Person in accordance with the terms of the Indenture or by such other means
as the Person entitled thereto and the Indenture Trustee shall agree, without
the presentation or surrender of this Class A-3 Note or the making of any
notation hereon.

                  The Holder hereof, by its acceptance of this Class A-3 Note,
agrees to look solely to the funds in the Collection Account to the extent
available for payment to the Holder hereof as provided in the Indenture for
payment hereunder and that the Indenture Trustee in its individual capacity is
not personally liable to the Holder hereof for any amounts due under this Class
A-3 Note or the Indenture. In addition, the Holder hereof, by its acceptance of
this Note, agrees to treat such Note as indebtedness of the Issuer and hereby
instructs the Indenture Trustee to treat such Note as indebtedness of the Issuer
for purposes of Federal, state and local income and franchise and any other
income taxes.

                  The Class A-3 Notes do not represent an obligation of, or an
interest in, First Union Trust Company, National Association, First Sierra or
any Affiliate thereof. The Class A-3 Notes are limited in right of payment to
certain collections and recoveries respecting the Contracts, all as more
specifically set forth above in the Indenture. Pursuant to the Indenture, the

the "Class A Notes" or the "Offered Notes") and Class B-1 Notes, Class B-2 Notes
and Class B-3 Notes (collectively the "Subordinate Notes") and pursuant to the
Trust Agreement, the Owner Trustee shall issue the Trust Certificate. THE RIGHT
TO RECEIVE PAYMENTS OF INTEREST WITH RESPECT TO EACH CLASS OF CLASS A NOTES IS

PAYMENTS OF PRINCIPAL WITH RESPECT TO EACH CLASS OF CLASS A NOTES IS ON A

BALANCE OF THE CLASS A NOTES THEN OUTSTANDING AND HAVING THE LOWEST NUMERICAL
DESIGNATION (E.G., FIRST TO THE CLASS A-1 NOTES) TO ZERO BEFORE ANY PRINCIPAL
PAYMENT IS MADE TO THE NEXT CLASS. THE RIGHT TO RECEIVE PAYMENTS WITH RESPECT TO
THE SUBORDINATE NOTES AND THE TRUST CERTIFICATE IS SUBORDINATE TO THE PRIOR
PAYMENT IN FULL OF ALL AMOUNTS OF PRINCIPAL AND INTEREST DUE AND PAYABLE ON THE
CLASS A NOTES ON EACH PAYMENT DATE.

                  The Indenture permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the Servicer and the rights of the Class A-3
Noteholders under the Indenture at any time by the Servicer, the Issuer and the
Indenture Trustee with the consent of the Majority Holders and the Note Insurer.
Any such consent by the Holder of this Class A-3 Note shall be conclusive and
binding on such Holder and upon all future Holders of this Class A-3 Note and of
any Class A-3 Note issued upon the transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent is made upon this Class A-3
Note. The Indenture also permits the amendment thereof, in certain limited
circumstances, without the consent of the Class A-3 Noteholders.

                  By its acceptance of this Class A-3 Note, each Holder shall be
deemed to have agreed that such Holder will not directly or indirectly
institute, or cause to be instituted, against the Residual 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.

                  As provided in the Indenture, the transfer of this Class A-3
Note is registrable in the Register upon surrender of this Class A-3 Note for
registration of transfer at the offices or agencies maintained by the Indenture
Trustee accompanied by a written instrument of transfer in form satisfactory to
the Indenture Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Class A-3
Notes of authorized denominations evidencing the same aggregate Class A-3
Percentage Interest in the Trust Property will be issued to the designated
transferee or transferees.

                  Each transferee of a beneficial interest in this Class A-3
Note shall be deemed to represent either (i) that it is not (A) an employee
benefit plan (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("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 Internal
Revenue Code of 1986, as amended (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 its
acquisition and continued holding of this Class A-3 Note will be covered by a
U.S. Department of Labor Prohibited Transaction Class Exemption.

                  The Class A-3 Notes are issuable only as registered Class A-3
Notes without coupons in minimum denominations of $1,000 of the Initial Class
A-3 Note Principal Amount. As provided in the Indenture and subject to certain
limitations therein set forth, Class A-3 Notes are exchangeable for new Class
A-3 Notes of authorized denominations evidencing the same aggregate Class A-3
Percentage Interest, as requested by the Class A-3 Noteholder surrendering the
same.

                  Unless earlier declared, or they otherwise become, due and
payable by reason of an Event of Default, the Notes are payable only at the time
and in the manner provided in the Indenture and are not redeemable or prepayable
before such time except that the Residual Holder will have the option, subject
to certain conditions set forth in the Indenture, including the deposit of the
sum specified in the Indenture, to cause early retirement of the Notes as of any
Payment Date following the date on which the aggregate Class A Note Principal
Balance and the Subordinate Note Principal Balance is less than 10% of the
Initial Class A Note Principal Amount and the Initial Subordinate Note Principal
Amount. In the event of such redemption, the entire outstanding Class A Note
Principal Balance and the Subordinate Note Principal Balance, together with
accrued interest thereon at the related Note Rate, will be required to be paid
to the respective Class A Noteholders and the respective Subordinate Noteholders
on such Payment Date. If an Event of Default as defined in the Indenture shall
occur and be continuing, the principal of all the Notes may become or be
declared due and payable in the manner and with the effect provided in the
Indenture.

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

                  The Servicer, the Issuer and the Indenture Trustee and any
agent of any of the foregoing may treat the person in whose name this Class A-3
Note is registered as the owner hereof for all purposes, and none of the
foregoing shall be affected by any notice to the contrary.

                        Class A-3 Notes, 5.450% Interest Rate

                  MBIA Insurance Corporation (the "Insurer") has issued a Note
Guaranty Insurance Policy (the "Policy") relating to the Class A-3 Notes
containing the following provisions, the Policy being on file at the Corporate
Trust Office of the Trustee (as defined herein).

                  The Insurer, in consideration of the payment of the premium
and subject to the terms of this Policy, hereby unconditionally and irrevocably
guarantees to any Owner that an amount equal to each full and complete Insured
Payment will be received by Bankers Trust Company, or its successor, as trustee
for the Owners (the "Trustee"), on behalf of the Owners from the Insurer, for
distribution by the Trustee to each Owner of each Owner's proportionate share of
the Insured Payment. The Insurer's obligations under the Policy with respect to
a particular Insured Payment shall be discharged to the extent funds equal to
the applicable Insured Payment are received by the Trustee, whether or not such
funds are properly applied by the Trustee. Insured Payments shall be made only
at the time set forth in the Policy, and no accelerated Insured Payments shall
be made regardless of any acceleration of the Class A-3 Notes, unless such
acceleration is at the sole option of the Insurer.

                  Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Trust or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                  The Insurer will pay any Insured Payment that is a Preference
Amount (as described below) on the Business Day following receipt on a Business
Day by the Fiscal Agent (as described below) of (i) a certified copy of the
order requiring the return of a preference payment, (ii) an opinion of counsel
satisfactory to the Insurer that such order is final and not subject to appeal,
(iii) an assignment in such form as is reasonably required by the Insurer,
irrevocably assigning to the Insurer all rights and claims of the Owner relating
to or arising under the Class A-3 Notes against the debtor which made such
preference payment or otherwise with respect to such preference payment and (iv)
appropriate instruments to effect the appointment of the Insurer as agent for
such Owner in any legal proceeding related to such preference payment, such
instruments being in a form satisfactory to the Insurer, provided that if such
documents are received after 12:00 noon, New York City time on such Business
Day, they will be deemed to be received on the following Business Day. Such
payments shall be disbursed to the receiver or trustee in bankruptcy named in
the final order of the court exercising jurisdiction on behalf of the Owner and
not to any Owner directly unless such Owner has returned principal or interest
paid on the Class A-3 Notes to such receiver or trustee in bankruptcy, in which
case such payment shall be disbursed to such Owner.

                  The Insurer will pay any other amount payable under the Policy
no later than 12:00 noon, New York City time, on the later of the Payment Date
on which the related Deficiency Amount is due or the second Business Day
following receipt in New York, New York on a Business Day by State Street Bank
and Trust Company, N.A., as Fiscal Agent for the Insurer or any successor fiscal
agent appointed by the Insurer (the "Fiscal Agent") of a Notice (as described
below); provided that if such Notice is received after 12:00 noon, New York City
time, on such Business Day, it will be deemed to be received on the following
Business Day. If any such Notice received by the Fiscal Agent is not in proper
form or is otherwise insufficient for the purpose of making claim under the
Policy, it shall be deemed not to have been received by the Fiscal Agent for
purposes of this paragraph, and the Insurer or the Fiscal Agent, as the case may
be, shall promptly so advise the Trustee and the Trustee may submit an amended
Notice.

                  Insured Payments due under the Policy, unless otherwise stated

extent not otherwise defined herein, the capitalized terms used herein have the
meanings assigned to them in the Indenture.

                  This Class A-4 Note is one of the duly authorized Class A-4
Notes designated as "5.628% Equipment Contract Backed Notes of First Sierra
Equipment Contract Trust 1998-1, Class A-4" (the "Class A-4 Notes"). This Class
A-4 Note is issued under and is subject to the terms, provisions and conditions
of the Indenture, to which Indenture the Holder of this Class A-4 Note, by
virtue of the acceptance hereof, assents and by which such Holder is bound.

                  This Class A-4 Note does not purport to summarize the
Indenture and reference is made to the Indenture for information with respect to
the interests, rights, benefits, obligations, proceeds and duties evidenced
hereby and the rights, duties and immunities of the Issuer. Copies of the
Indenture and all amendments thereto will be provided to any Class A-4
Noteholder, at its expense, upon a written request to the Servicer: 600 Travis
Street, Suite 7050, Houston, Texas 77002; Attention: Sandy Ho, Chief Financial

                  Under the Indenture, the Issuer is obligated to cause the
Indenture Trustee to pay, to the extent that monies are available in the
Collection Account for such distributions, on the 12th day of each Payment Date,

                  Payments on this Class A-4 Note will be made by the Indenture
Trustee by check mailed, or upon request of the Holder hereof, by wire transfer
of immediately available funds, to the Person entitled thereto, as specified by
such Person in accordance with the terms of the Indenture or by such other means
as the Person entitled thereto and the Indenture Trustee shall agree, without
the presentation or surrender of this Class A-4 Note or the making of any
notation hereon.

                  The Holder hereof, by its acceptance of this Class A-4 Note,
agrees to look solely to the funds in the Collection Account to the extent
available for payment to the Holder hereof as provided in the Indenture for
payment hereunder and that the Indenture Trustee in its individual capacity is
not personally liable to the Holder hereof for any amounts due under this Class
A-4 Note or the Indenture. In addition, the Holder hereof, by its acceptance of
this Note, agrees to treat such Note as indebtedness of the Issuer and hereby
instructs the Indenture Trustee to treat such Note as indebtedness of the Issuer
for purposes of Federal, state and local income and franchise and any other
income taxes.

                  The Class A-4 Notes do not represent an obligation of, or an
interest in, First Union Trust Company, National Association, First Sierra or
any Affiliate thereof. The Class A-4 Notes are limited in right of payment to
certain collections and recoveries respecting the Contracts, all as more
specifically set forth above in the Indenture. Pursuant to the Indenture, the
Indenture Trustee shall, in addition to the Class A-4 Notes, issue Class A-1
Notes, Class A-2 Notes and Class A-3 Notes (together with the Class A-4 Notes,
the "Class A Notes" or the "Offered Notes") and Class B-1 Notes, Class B-2 Notes
and Class B-3 Notes (collectively the "Subordinate Notes") and pursuant to the
Trust Agreement, the Owner Trustee shall issue the Trust Certificate. THE RIGHT
TO RECEIVE PAYMENTS OF INTEREST WITH RESPECT TO EACH CLASS OF CLASS A NOTES IS
PARI PASSU WITH EACH OTHER CLASS OF CLASS A NOTES AND THE RIGHT TO RECEIVE
PAYMENTS OF PRINCIPAL WITH RESPECT TO EACH CLASS OF CLASS A NOTES IS ON A

SEQUENTIAL-PAY BASIS WHEREBY PRINCIPAL IS APPLIED TO REDUCE THE NOTE PRINCIPAL
BALANCE OF THE CLASS A NOTES THEN OUTSTANDING AND HAVING THE LOWEST NUMERICAL
DESIGNATION (E.G., FIRST TO THE CLASS A-1 NOTES) TO ZERO BEFORE ANY PRINCIPAL
PAYMENT IS MADE TO THE NEXT CLASS. THE RIGHT TO RECEIVE PAYMENTS WITH RESPECT TO
THE SUBORDINATE NOTES AND THE TRUST CERTIFICATE IS SUBORDINATE TO THE PRIOR
PAYMENT IN FULL OF ALL AMOUNTS OF PRINCIPAL AND INTEREST DUE AND PAYABLE ON THE
CLASS A NOTES ON EACH PAYMENT DATE.

                  The Indenture permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer and the Servicer and the rights of the Class A-4
Noteholders under the Indenture at any time by the Servicer, the Issuer and the
Indenture Trustee with the consent of the Majority Holders and the Note Insurer.
Any such consent by the Holder of this Class A-4 Note shall be conclusive and
binding on such Holder and upon all future Holders of this Class A-4 Note and of
any Class A-4 Note issued upon the transfer hereof or in exchange hereof or in
lieu hereof whether or not notation of such consent is made upon this Class A-4
Note. The Indenture also permits the amendment thereof, in certain limited
circumstances, without the consent of the Class A-4 Noteholders.

                  By its acceptance of this Class A-4 Note, each Holder shall be
deemed to have agreed that such Holder will not directly or indirectly
institute, or cause to be instituted, against the Residual 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.

                  As provided in the Indenture, the transfer of this Class A-4
Note is registrable in the Register upon surrender of this Class A-4 Note for
registration of transfer at the offices or agencies maintained by the Indenture
Trustee accompanied by a written instrument of transfer in form satisfactory to
the Indenture Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Class A-4
Notes of authorized denominations evidencing the same aggregate Class A-4
Percentage Interest in the Trust Property will be issued to the designated
transferee or transferees.

                  Each transferee of a beneficial interest in this Class A-4
Note shall be deemed to represent either (i) that it is not (A) an employee
benefit plan (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("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 Internal
Revenue Code of 1986, as amended (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 its
acquisition and continued holding of this Class A-4 Note will be covered by a
U.S. Department of Labor Prohibited Transaction Class Exemption.

                  The Class A-4 Notes are issuable only as registered Class A-4
Notes without coupons in minimum denominations of $1,000 of the Initial Class
A-4 Note Principal Amount. As provided in the Indenture and subject to certain
limitations therein set forth, Class A-4 Notes are exchangeable for new Class
A-4 Notes of authorized denominations evidencing the same aggregate Class A-4
Percentage Interest, as requested by the Class A-4 Noteholder surrendering the
same.

                  Unless earlier declared, or they otherwise become, due and
payable by reason of an Event of Default, the Notes are payable only at the time
and in the manner provided in the Indenture and are not redeemable or prepayable
before such time except that the Residual Holder will have the option, subject
to certain conditions set forth in the Indenture, including the deposit of the
sum specified in the Indenture, to cause early retirement of the Notes as of any
Payment Date following the date on which the aggregate Class A Note Principal
Balance and the Subordinate Note Principal Balance is less than 10% of the
Initial Class A Note Principal Amount and the Initial Subordinate Note Principal
Amount. In the event of such redemption, the entire outstanding Class A Note
Principal Balance and the Subordinate Note Principal Balance, together with
accrued interest thereon at the related Note Rate, will be required to be paid
to the respective Class A Noteholders and the respective Subordinate Noteholders
on such Payment Date. If an Event of Default as defined in the Indenture shall
occur and be continuing, the principal of all the Notes may become or be
declared due and payable in the manner and with the effect provided in the
Indenture.

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

                  The Servicer, the Issuer and the Indenture Trustee and any
agent of any of the foregoing may treat the person in whose name this Class A-4
Note is registered as the owner hereof for all purposes, and none of the
foregoing shall be affected by any notice to the contrary.

                        Class A-4 Notes, 5.628% Interest Rate

                  MBIA Insurance Corporation (the "Insurer") has issued a Note
Guaranty Insurance Policy (the "Policy") relating to the Class A-4 Notes
containing the following provisions, the Policy being on file at the Corporate
Trust Office of the Trustee (as defined herein).

                  The Insurer, in consideration of the payment of the premium
and subject to the terms of this Policy, hereby unconditionally and irrevocably
guarantees to any Owner that an amount equal to each full and complete Insured
Payment will be received by Bankers Trust Company, or its successor, as trustee
for the Owners (the "Trustee"), on behalf of the Owners from the Insurer, for
distribution by the Trustee to each Owner of each Owner's proportionate share of
the Insured Payment. The Insurer's obligations under the Policy with respect to
a particular Insured Payment shall be discharged to the extent funds equal to
the applicable Insured Payment are received by the Trustee, whether or not such
funds are properly applied by the Trustee. Insured Payments shall be made only
at the time set forth in the Policy, and no accelerated Insured Payments shall
be made regardless of any acceleration of the Class A-4 Notes, unless such
acceleration is at the sole option of the Insurer.

                  Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Trust or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                  The Insurer will pay any Insured Payment that is a Preference
Amount (as described below) on the Business Day following receipt on a Business
Day by the Fiscal Agent (as described below) of (i) a certified copy of the
order requiring the return of a preference payment, (ii) an opinion of counsel
satisfactory to the Insurer that such order is final and not subject to appeal,
(iii) an assignment in such form as is reasonably required by the Insurer,
irrevocably assigning to the Insurer all rights and claims of the Owner relating
to or arising under the Class A-4 Notes against the debtor which made such
preference payment or otherwise with respect to such preference payment and (iv)
appropriate instruments to effect the appointment of the Insurer as agent for
such Owner in any legal proceeding related to such preference payment, such
instruments being in a form satisfactory to the Insurer, provided that if such
documents are received after 12:00 noon, New York City time on such Business
Day, they will be deemed to be received on the following Business Day. Such
payments shall be disbursed to the receiver or trustee in bankruptcy named in
the final order of the court exercising jurisdiction on behalf of the Owner and
not to any Owner directly unless such Owner has returned principal or interest
paid on the Class A-4 Notes to such receiver or trustee in bankruptcy, in which
case such payment shall be disbursed to such Owner.

                  The Insurer will pay any other amount payable under the Policy
no later than 12:00 noon, New York City time, on the later of the Payment Date
on which the related Deficiency Amount is due or the second Business Day
following receipt in New York, New York on a Business Day by State Street Bank
and Trust Company, N.A., as Fiscal Agent for the Insurer or any successor fiscal
agent appointed by the Insurer (the "Fiscal Agent") of a Notice (as described
below); provided that if such Notice is received after 12:00 noon, New York City
time, on such Business Day, it will be deemed to be received on the following
Business Day. If any such Notice received by the Fiscal Agent is not in proper
form or is otherwise insufficient for the purpose of making claim under the
Policy, it shall be deemed not to have been received by the Fiscal Agent for
purposes of this paragraph, and the Insurer or the Fiscal Agent, as the case may
be, shall promptly so advise the Trustee and the Trustee may submit an amended
Notice.

                  Insured Payments due under the Policy, unless otherwise stated
in the Policy, will be disbursed by the Fiscal Agent to the Trustee on behalf of
the Owners by wire transfer of immediately available funds in the amount of the
Insured Payment less, in respect of Insured Payments related to Preference
Amounts, any amount held by the Trustee for the payment of such Insured Payment
and legally available therefor.

                  The Fiscal Agent is the agent of the Insurer only, and the
Fiscal Agent shall in no event be liable to Owners for any acts of the Fiscal
Agent or any failure of the Insurer to deposit, or cause to be deposited,
sufficient funds to make payments due under the Policy.

                  Subject to the terms of the Agreement, the Insurer shall be
subrogated to the rights of each Owner to receive payments under the Class A-4
Notes to the extent of any payment by the Insurer under the Policy.

                  As used in the Policy, the following terms shall have the
following meanings:

                  "Agreement" means the Indenture dated as of December 1, 1998

attorney duly authorized in writing, and thereupon one or more new Class B-1
Notes of authorized denominations evidencing the same aggregate Class B-1
Percentage Interest in the Trust Property will be issued to the designated
transferee or transferees.

                  The transfer of this Class B-1 Note shall not be registered
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 the Employee Retirement
Income Security Act of 1974, as amended ("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 Internal Revenue Code of 1986, as amended (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 this Class B-1 Note will

limitations therein set forth, Class B-1 Notes are exchangeable for new Class
B-1 Notes of authorized denominations evidencing the same aggregate Class B-1
Percentage Interest, as requested by the Class B-1 Noteholder surrendering the
same.

                  Unless earlier declared, or they otherwise become, due and
payable by reason of an Event of Default, the Notes are payable only at the time
and in the manner provided in the Indenture and are not redeemable or prepayable
before such time except that the Residual Holder will have the option, subject
to certain conditions set forth in the Indenture, including the deposit of the
sum specified in the Indenture, to cause early retirement of the

Notes as of any Payment Date following the date on which the aggregate Class A
Note Principal Balance and the Subordinate Note Principal Balance is less than
10% of the Initial Class A Note Principal Amount and the Initial Subordinate
Note Principal Amount. In the event of such redemption, the entire outstanding
Class A Note Principal Balance and the Subordinate Note Principal Balance,
together with accrued interest thereon at the related Note Rate, will be
required to be paid to the respective Class A Noteholders and the respective
Subordinate Noteholders on such Payment Date. If an Event of Default as defined
in the Indenture shall occur and be continuing, the principal of all the Notes
may become or be declared due and payable in the manner and with the effect
provided in the Indenture.

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

                  The Servicer, the Issuer and the Indenture Trustee and any
agent of any of the foregoing may treat the person in whose name this Class B-1
Note is registered as the owner hereof for all purposes, and none of the
foregoing shall be affected by any notice to the contrary.

Percentage Interest in the Trust Property will be issued to the designated
transferee or transferees.

                  The transfer of this Class B-2 Note shall not be registered

employee benefit plan (as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) that is subject to the

to Section 4975 of the Code (each of the foregoing, a "Benefit Plan"), and is

together with accrued interest thereon at the related Note Rate, will be
required to be paid to the respective Class A Noteholders and the respective
Subordinate Noteholders on such Payment Date. If an Event of Default as defined

may become or be declared due and payable in the manner and with the effect
provided in the Indenture.

transfer or exchange, but the Indenture Trustee may require payment of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

                  The Servicer, the Issuer and the Indenture Trustee and any
agent of any of the foregoing may treat the person in whose name this Class B-2
Note is registered as the owner hereof for all purposes, and none of the
foregoing shall be affected by any notice to the contrary.

                                       1
<PAGE>   124

         ___      Investment Advisor. The Purchaser is an investment advisor
                  registered under the Investment Advisers Act of 1940.


                  3. The term "securities" as used herein does not include (i)
securities of issuers that are affiliated with the Purchaser, (ii) securities
that are part of an unsold allotment to or subscription by the Purchaser, if the
Purchaser is a dealer, (iii) bank deposit notes and certificates of deposit,
(iv) loan participations, (v) repurchase agreements, (vi) securities owned but
subject to a repurchase agreement and (vii) currency, interest rate and
commodity swaps.


                  4. For purposes of determining the aggregate amount of
securities owned and/or invested on a discretionary basis by the Purchaser, the
Purchaser used the cost of such securities to the Purchaser and did not include
any of the securities referred to in the preceding paragraph. Further, in
determining such aggregate amount, the Purchaser may have included securities
owned by subsidiaries of the Purchaser, but only if such subsidiaries are
consolidated with the Purchaser in its financial statements prepared in
accordance with generally accepted, accounting principles and if the investments
of such subsidiaries are managed under the Purchaser's direction. However, such
securities were not included if the Purchaser is a majority-owned, consolidated
subsidiary of another enterprise and the Purchaser is not itself a reporting
company under the Securities Exchange Act of 1934.


                  5. The Purchaser acknowledges that it is familiar with Rule
144A and understands that the seller to it and other parties related to the
Notes are relying and will continue to rely on the statements made herein
because one or more sales to the Purchaser may be in reliance on Rule 144A.


      ____             ___       Will the Purchaser be purchasing the Note
      Yes              No        only for the Purchaser's own account?


                  6. If the answer to the foregoing question is "no", the
Purchaser agrees that, in connection with any purchase of securities sold to the
Purchaser for the account of a third party (including any separate account) in
reliance on Rule 144A, the Purchaser will only purchase for the account of a
third party that at the time is a "qualified institutional buyer" within the
meaning of Rule 144A. In addition, the Purchaser agrees that the Purchaser will
not purchase securities for a third party unless the Purchaser has obtained a
current representation letter from such third party or taken other appropriate
steps contemplated by Rule 144A to conclude that such third party independently
meets the definition of "qualified institutional buyer" set forth in Rule 144A.


                  7. The Purchaser will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice is given, the Purchaser's purchase of the Note will constitute
a reaffirmation of this certification as of the date of such purchase.

To the Parties Listed on Schedule I:


Ladies and Gentlemen:

                  We have acted as special tax counsel to First Sierra
Financial, Inc. ("First Sierra") and First Sierra Receivables III, Inc. (the
"Depositor"), in connection with the issuance by First Sierra Equipment Contract
Trust 1998-1, a Delaware common law trust acting through First Union Trust
Company, National Association, not in its individual capacity but solely as
Owner Trustee (the "Trust"), established pursuant to a Trust Agreement, dated as
of December 1, 1998, between the Depositor and First Union Trust Company,
National Association, not in its individual capacity but solely as owner
trustee, of (i) $70,687,140 of 5.215% Equipment Contract Backed Notes, Class A-1
(the "Class A-1 Notes"), (ii) $53,856,869 of 5.490% Equipment Contract Backed
Notes, Class A-2 (the "Class A-2 Notes"), (iii) $52,510,447 of 5.450% Equipment
Contract Backed Notes, Class A-3 (the "Class A-3 Notes"), (iv) $70,687,140 of
5.628% Equipment Contract Backed Notes, Class A-4 (the "Class A-4 Notes" and,
together with the Class A-1 Notes, the Class A-2 Notes and the Class A-3 Notes,
the "Class A Notes"), (v) $5,385,687 of 7.340% Equipment Contract Backed Notes,
Class B-1 (the "Class B-1 Notes"), (vi) $2,692,843 of 9.510% Equipment Contract
Backed Notes, Class B-2 (the "Class B-2 Notes"), and (vii) $5,385,687 of 6.242%
Equipment Contract Backed Notes, Class B-3 (the "Class B-3 Notes"). The Class A
Notes, the Class B-1 Notes, the Class B-2 Notes and the Class B-3 Notes are
collectively referred to as the "Notes." The Notes were issued pursuant to an
Indenture, dated as of December 1, 1998 (the "Indenture"), among the Trust,
First Sierra, as servicer and as originator, and Bankers Trust Company, as
indenture trustee (the "Indenture Trustee"). Pursuant to the Indenture, the
Pledged Property (as defined in the Indenture) will be pledged by the Trust to
the Indenture Trustee for the benefit of the Noteholders. Capitalized terms used
herein, unless otherwise defined, shall have the meanings set forth in the
Indenture.

                  You have asked for our opinion concerning the tax treatment 
of the Notes for Federal income tax purposes. Although no transaction closely
comparable to the transactions contemplated by the Indenture has been the
subject of any Treasury regulation, revenue ruling, or judicial decision,
subject to the assumptions and qualifications set forth below, it is our opinion
that, for Federal income tax purposes, the Notes, other than the Class B-3
Notes, will be characterized as indebtedness. In addition, it is our opinion for
Federal income tax purposes, that the Trust will not be characterized as an
association or as a publicly traded partnership taxable as a corporation.
Further, it is our opinion that the Notes, other than the Class B-3 Notes, will
be 


<PAGE>   2

treated as indebtedness under the laws of the State of New York. In addition,
we confirm that the discussion of federal income tax consequences appearing in
the Prospectus and in the Prospectus Supplement under the caption "Material
Federal Income Tax Consequences" is our opinion as to the material federal
income tax consequences of purchasing, owning and disposing of the securities
and expressly adopt it as such.

                  Our opinion is based, in part, upon (i) the agreement of the
Company, the Depositor, the Trust, the Indenture Trustee and the Noteholders to
treat the Notes for Federal, state, local, foreign, and other tax purposes as
indebtedness (and assumed compliance with such agreement) and (ii) our
conclusion that the Federal income tax treatment of the Notes will be determined
based on the economic substance of the transactions resulting from the
Indenture. Although there can be no assurance that the Internal Revenue Service
(the "IRS") will not take one or more possible contrary positions, it is our
opinion that none of those positions, if asserted by the IRS, would prevail. Our
opinion is based upon the present provisions of the Internal Revenue Code of
1986 as amended, the regulations promulgated thereunder, and judicial or ruling
authority, all of which are subject to change, which change may be retroactive.
No ruling on any issue discussed above will be sought from the IRS.

                  Our opinion contained herein is rendered only as of the date
hereof, and we undertake no obligation to update this letter or the opinion
contained herein after the date hereof. We hereby expressly reserve our opinion
with regard to the Class B-3 Notes.

                  This opinion is furnished by us as counsel in connection with
the issuance of the Notes, and is not to be used, circulated, quoted, or
otherwise referred to for any other purpose without our express written consent.

                                             Very truly yours,

                                             /s/ Dewey Ballantine LLP

                  (e) Except for the obligations of First Sierra pursuant to the
Servicing Agreement and the Indenture with respect to any breach of a
representation, warranty or covenant made herein, the sale and conveyance of the
Contracts will be without recourse to the Sellers.

                  SECTION 2.02 Custody of Contract Files. In connection with the
sale, assignment, transfer and conveyance of the Contracts to the Trust pursuant
to this Agreement, First Sierra, as Servicer under the Servicing Agreement and
as agent of the Indenture Trustee will retain the Contract Files and any related
evidence of insurance and payments; provided, however, that First Sierra will
physically convey the original executed counterparts of each Contract and the
related Certificate of Title, if applicable, to the Indenture Trustee in
accordance with the terms of the Indenture.

                  SECTION 2.03 Intention of the Parties; Grant of Security
Interest. It is the intention of the parties hereto that each transfer of the
Conveyed Released 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
Released Asset, and all income and proceeds thereof.

                             (xi) Fair Consideration. The consideration received
             by Receivables III as set forth herein is fair consideration having
             value reasonably equivalent to or in excess of the value of the

             III's obligation hereunder; and

                             (xii) Principal Place of Business. The principal

             with respect to such changes occurring after the date of this
             Agreement, as shall have been specifically disclosed to the

<PAGE>   12

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

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

                             (xv) Accounting Treatment. Receivables III 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, except with respect to
             a portion of the Conveyed Assets which will be treated as owned by
             Receivables III and which will be treated as consolidated for
             accounting purposes with First Sierra.

             state law, in each case, where the failure to be so qualified,

             materially and adversely to affect the ability of Prudential to
             comply with the terms of this Agreement or any other transaction
             document to which it is a party;

                             (iii) Power and Authority. Prudential has the

             behalf of the Trust, of all right, title, and interest of
             Prudential 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 Prudential, 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 Prudential enforceable against Prudential in
             accordance with its 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 Prudential, or any material term of any
             indenture, agreement, mortgage, deed of trust, or other instrument
             to which Prudential 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 Prudential of any court or of any
             federal or state regulatory body, administrative agency, or other
             Governmental Authority having jurisdiction over Prudential or any
             of its properties which would have a material adverse effect on the
             Conveyed Assets;

                             (vii) Valid Business Reasons. Prudential 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 Prudential's operations or its ability to
             perform its obligations under the Transaction Documents to which it
             is a party;

                             (ix) Insolvency. Prudential 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 Transaction Document to which it is a
             party;

                             (x) No Proceedings. There are no proceedings or
             investigations pending, or, to the knowledge of Prudential,
             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 Prudential) materially and adversely
             affect the performance by Prudential of its obligations under, or
             the validity or enforceability of, this Agreement;



                                       11
<PAGE>   14

                             (xi) No Consent Required. Prudential 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 Prudential 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
             Prudential's obligations hereunder; and

                             (xiii) Accounting Treatment. Prudential 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.

                  (d) First Union hereby makes the following representations and
warranties for the benefit of the Indenture Trustee, the Noteholders, the Note

             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 First Union to
             comply with the terms of this Agreement or any other Transaction
             Document to which it is a party;

                             (iii) Power and Authority. First Union has the

                             (v) Valid Assignment; Binding Obligations. This
             Agreement constitutes a valid contribution, assignment, transfer
             and conveyance to the Owner Trustee, on behalf of the Trust, of all
             right, title, and interest of First Union 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
             First Union, 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 legal,
             valid, and binding obligation of First Union enforceable against
             First Union in accordance with their respective terms subject as to

                             (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

             notice or lapse of time) a default under, the articles of
             incorporation or bylaws of First Union, or any material term of any
             indenture, agreement, mortgage, deed of trust, or other instrument
             to which First Union 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

             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

             received by First Union as set forth herein is fair consideration
             having value reasonably equivalent to or in excess of the value of

             the assignment of the Conveyed Assets to the Trust pursuant to

             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 VFCC to comply
             with the terms of this Agreement or any other Transaction Document
             to which it is a party;

                             (iii) Power and Authority. VFCC has the corporate

             Trustee granted pursuant to the Indenture; and this Agreement, when

                  SECTION 3.02 [Reserved]

                  SECTION 3.03 Substitution of Contracts and Equipment by First
Sierra.

                  (a) With respect to a substitution of Contracts in accordance
with the provisions of this Section 3.03 and Section 4.02 of the Indenture, each
proposed Substitute Contract must (i) be an Eligible Contract, (ii) satisfy all
of the representations and warranties set forth in Section 2.02 of the Servicing
Agreement, (iii) have a Discounted Contract Principal Balance of not less than
the Discounted Contract Principal Balance of the Contract being replaced and
(iv) is eligible to be substituted by First Sierra under the Indenture. For
purposes of determining compliance with clause (iii) of the preceding sentence,
if more than one Substitute Contract is being provided on any date, the
Discounted Contract Principal Balance of the Substitute Contracts and the
Contracts being replaced shall be determined on an aggregate basis.

                  (b) Any substitution of a Contract pursuant to this Agreement
will be effected by (i) delivery to the Indenture Trustee of the Contract File
for each such Substitute Contracts, (ii) filing of any UCC financing statements
necessary to perfect the interest of the Indenture Trustee in the Substitute
Contracts, (iii) delivery to the Indenture Trustee of a supplement to the List
of Contracts reflecting such substitution and (iv) delivery to the Indenture
Trustee of a release request and the originally executed trust receipt relating
thereto.

                  (c) The parties hereto agree that in addition to the
obligation of First Sierra 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, First Sierra will enforce
its remedies against any Source under any Source Agreement. In consideration of
the purchase of the Equipment and the Contract, First Sierra 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 First
Sierra with respect to a breach as provided in this Section 3.03 and Section


                                       16
<PAGE>   19

4.01 of the Indenture constitute the sole remedy against First Sierra for such
breach available to the Trust, the Note Insurer, the Indenture Trustee and
Noteholders. The representations and warranties set forth in Sections 3.01 and
3.02 shall survive the assignment of the Conveyed Assets to 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

                  SECTION 4.01 Seller and First Sierra Covenants. First Sierra
and the Sellers, as applicable, hereby covenant and agree with the Trust, the
Note Insurer, 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 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. First Sierra shall deliver (or cause
to be delivered) to the Trust file-stamped copies of, or filing receipts for,
any document filed as provided above, as soon as available following such
filing.

                  (b) Obligations with Respect to Conveyed Assets. Each of the
Sellers will duly fulfill all obligations on its part to be fulfilled under or
in connection with each Contract and each Source Agreement, and will do nothing
to impair the rights of the Trust, the Note Insurer or the Indenture Trustee in
any of the Conveyed Assets.

                  (c) Compliance with Law. First Sierra will comply, in all
material respects, with all acts, rules, requisitions, orders, decrees and
directions of any Governmental Authority applicable to its business and to the
Conveyed Assets or any part thereof; provided, however, that First Sierra 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, the Note Insurer or the Owner Trustee in the Conveyed Assets.

                  (d) Conveyance of Conveyed Assets; Security Interests. Except
for the transfers and conveyances hereunder, or under any Transaction Document,
the Sellers will not sell, pledge, assign or transfer to any other Person, or
grant, create, incur, assume or suffer to exist any Lien, on any Conveyed Asset,
or any interest therein and First Sierra shall defend the right, title, and
interest of the Owner Trustee, on behalf of the Trust, the Indenture Trustee,
the Note Insurer 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(f) shall
prevent or be deemed to prohibit First Sierra from suffering to exist upon any
of the Conveyed Assets any Liens for municipal or other local taxes if such


                                       17
<PAGE>   20

taxes shall not at the time be due and payable or if First Sierra 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,
the Indenture Trustee and the Note Insurer promptly, in reasonable detail, upon
discovery of the occurrence of any breach by First Sierra of any of its
representations, warranties and covenants contained herein.

                  (f) Further Assurances. (i) First Sierra will make, execute or
             endorse, acknowledge and file or deliver to the Trust and the
             Indenture Trustee from time to time such schedules, confirmatory
             assignments, conveyances, transfer endorsements, powers of
             attorney, certificates, 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, the Note
             Insurer 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 Note Insurer, and the rating, issuance
             and sale of the Notes.

                  (g) Indemnification. First Sierra agrees to indemnify, defend
and hold the Trust, the Note Insurer and the Indenture Trustee harmless from and
against any and all loss, liability, damage, judgment, claim, deficiency, or
expense (including interest, penalties, reasonable attorneys' fees and amounts
paid in settlement) to which any of them may become subject insofar as such
loss, liability, damage, judgment, claim, deficiency, or expense arises out of
or is based upon a breach by First Sierra of its covenants contained in Section
4.01, or any information certified set forth in this Agreement or in any
schedule delivered by First Sierra hereunder, being untrue in any material
respect at any time. The obligations of First Sierra under this Section 4.01(g)
shall be considered to have been relied upon by the Trust, the Note Insurer and
the Indenture Trustee and shall survive the execution, delivery, and performance
of this Agreement regardless of any investigation made by the Trust, the
Indenture Trustee, the Note Insurer or on their respective behalf. THE
INDEMNIFICATION OBLIGATIONS OF FIRST SIERRA PURSUANT TO THE PRECEDING PROVISIONS
OF THIS PARAGRAPH SHALL APPLY REGARDLESS OF ANY NEGLIGENCE OR OTHER FAULT ON THE
PART OF THE TRUST, THE INDENTURE TRUSTEE, THE NOTE INSURER OR ANY OF THEIR
RESPECTIVE OFFICERS, EMPLOYEES OR AGENTS.

                  (h) Notice of Liens. First Sierra shall notify the Trust, the
Note Insurer and the Indenture Trustee, promptly after becoming aware of any
Lien on any Conveyed Asset.

                  (i) Taxes. First Sierra shall promptly pay all applicable
taxes required to be paid in connection with the assignment of the Conveyed
Assets and acknowledges that the Trust 



                                       18
<PAGE>   21

shall have no responsibility with respect thereto. First Sierra 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 thereafter without penalty or (ii) such as may be
contested in good faith by appropriate proceedings and for which an adequate
reserve has been established and is maintained in accordance with GAAP. First
Sierra shall promptly notify the Trust, the Indenture Trustee, the Note Insurer
and the Noteholders of any material challenge, contest or proceeding pending by
or against First Sierra before any taxing authority. First Sierra and the
Depositor shall enter into a Tax Sharing Agreement, pursuant to which (i) First
Sierra 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 First Sierra in respect
of its separate federal income tax liability. So long as any Notes remain
outstanding, First Sierra and the Depositor shall not terminate or amend such
Tax Sharing Agreement without the prior written consent of the Indenture Trustee
acting upon the written direction of the Note Insurer, except that First Sierra
shall not require the Depositor to make any payments to First Sierra, 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. First Sierra shall promptly
pay and discharge all material taxes, assessments, fees, claims and other
governmental charges when due and payable by First Sierra, the First Sierra
Group, or any member of the First Sierra Group, except (i) such as may be paid
thereafter without penalty or (ii) such as may be contested in good faith by
appropriate proceedings and for which an adequate reserve has been established
and is maintained in accordance with GAAP. First Sierra shall promptly notify
the Trust, the Note Insurer and the Indenture Trustee of any material challenge,
contest or proceeding pending by or against First Sierra or the First Sierra
Group before any taxing authority.

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

                  (l) No Agency. First Sierra will not act as an agent of
Receivables III or Holding Trust I 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 I;

                  (m) Financial Statements. The financial statements and books
and records of First Sierra reflect the separate existence of Receivables III
and Holding Trust I.

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



                                       19
<PAGE>   22

                  (a) Receivables III Certificate. Prior to each date as of
which Contracts and the interest of Receivables III in the Equipment subject to
such Contracts are to be re-purchased by First Sierra pursuant to the Indenture,
Receivables III shall submit to First Sierra a certificate signed by the
president, executive vice president, any vice president or the treasurer of
Receivables III (a "Receivables III Certificate"), executed by Receivables III
and completed as to its date and the date of this Agreement. Each Receivables
III Certificate shall operate as an assignment, without recourse,
representation, or warranty, to First Sierra of all Receivables III's right,
title, and interest in and to such purchased Contract, Receivables III's
interest in the related Equipment, and all security and documents relating
thereto, such assignment being an assignment outright and not for security; and
upon payment of the Repurchase Amount, First Sierra will thereupon own such
Contract, such interest in the related Equipment and all such security and
documents, free of any further obligation to Receivables III with respect
thereto. If in any enforcement suit or legal proceeding it is held that the
Servicer may not enforce a Contract on the ground that it is not a real party in
interest or holder entitled to enforce the Contract, Receivables III shall, at
the Servicer's expense, take such steps as the Servicer deems necessary to
enforce the Contract, including bringing suit in Receivables III's name.

                  (b) 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.

                  (c) 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;

                           (iii) not be involved in the day-to-day management of
         First Sierra and/or Holding Trust I;

                           (iv) not incur, assume or guarantee any indebtedness
         except for such indebtedness as may be incurred by Receivables III in
         connection with the issuance of the Notes or as otherwise permitted by
         the Note Insurer;

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



                                       20
<PAGE>   23

                             (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, First Sierra's creditors or Holding Trust I'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;

                             (ix) not engage in any business or activity other
             than in connection with or relating to its Certificate of
             Incorporation and/or Bylaws;

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

                             (xi) comply with all restrictions and covenants in,
             and shall 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 First Sierra (including through the maintenance of a
             separate bank account);

                             (xiii) manage its day-to-day business without the
             involvement of First Sierra and/or Holding Trust I;

                             (xiv) maintain a separate office from that of First
             Sierra and/or Holding Trust I;

                             (xv) not act as an agent of First Sierra or Holding
             Trust I, except to the limited extent provided in the Transaction
             Documents; and

                             (xvi) maintain at all times two independent
             directors as required by its Certificate of Incorporation and/or 
             Bylaws.

                  (d) 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 



                                       21
<PAGE>   24

         assumption to perform all of Receivables III's obligations under this
         Agreement, and upon such execution will be Receivables III's successor
         under this Agreement, without the execution or filing of any document
         or any further act on the part of any of the parties to this Agreement,
         anything in this Agreement 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 Note Insurer, 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, merger, or
         succession and such agreement of assumption comply with this Section
         4.02(d) 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 Note Insurer, 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, (d) such partnership or corporation shall
         have organizational documents with similar restrictions as those of
         Receivables III, and (e) the Note Insurer has given its prior written
         consent.

                  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 Note Insurer and
the Noteholders, pursuant to the Indenture. Each Seller 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.

                              CONDITIONS PRECEDENT

                  SECTION 5.01 Conditions to Trust Obligations. The obligations
of the Trust to accept the transfer of the Conveyed Assets on the Closing Date
shall be subject to the satisfaction of the following conditions:

                  (a) All representations and warranties of each Seller,
Receivables III and each Investor contained in this Agreement shall be true and
correct on the Closing Date with the same effect as though such representations
and warranties had been made on such date;

                  (b) All information concerning the Conveyed Assets provided to
the Trust shall be true and correct as of the Cut-Off Date in all material
respects;

                  (c) Each Seller shall have delivered to the Trust a List of
Contracts with respect to its respective Contracts as of the Cut-Off Date and
shall have substantially performed all other obligations required to be
performed by the provisions of this Agreement;

                  (d) Each Seller shall have recorded and filed, at its expense,
any financing statement with respect to the Contracts and the other Conveyed
Assets to be transferred from time to time to 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 Contracts and the other Conveyed Assets from each such Seller to the Owner
Trustee, on behalf of Trust, and shall deliver a file-stamped copy of such
financing statements or other evidence of such filings to the Trust;

                  (e) All corporate and legal proceedings and all instruments in
connection with the transactions contemplated by this Agreement shall be
satisfactory in form and substance to the Trust, and the Trust shall have
received from each Seller copies of all documents (including, without

herein contemplated as the Trust may reasonably have requested; and

                  (f) All respective conditions necessary to vest in each Seller
good title, free and clear of all Liens (other than Liens permitted in the

                                   ARTICLE VI

                                   TERMINATION

                  SECTION 6.01 Termination. The respective obligations and
responsibilities of each Seller, First Sierra 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, 



                                       23

that the indemnifications contained in Section 4.01(g) herein shall survive the
termination of this Agreement.

                  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,
neither the failure of the Trust to deliver a Trust Certificate pursuant to
Section 4.02, nor the failure of First Sierra to pay a Repurchase Amount shall
render such transfer or obligation executory, nor shall the continued duties of
the parties pursuant to Article 4 or Section 7.06 of this Agreement render an
executed sale executory.


                                   ARTICLE VII
