3.       Exercise Procedure Prior to Registration.

                  (a) Until the holder of Options has been notified by Conexant
that a registration statement registering the Option Shares to be issued upon
exercise of the Options (the "Registration Statement") has been declared
effective by the Securities and Exchange Commission (the "SEC"), to exercise all
or any part of Options any holder of Options (or any other person entitled to

that the exercise contain or be accompanied by written acknowledgment that such
holder is making the representations and warranties contained in Section 8 as of
the date of exercise. In addition, in the case of an exercise of the Options by
any person other than the original holder seeking to exercise the Options, the
Secretary of Conexant may require additional documents to establish to its
satisfaction that the person seeking to exercise the Options is entitled to do
so.

                  (c) An exercise of the whole or any part of the Options shall
be effective:

                  (i) if a holder of Options elects to pay the exercise price
         for the Option Shares entirely in cash, after full payment of the
         exercise price and personal withholding taxes (if applicable) is made
         to Conexant (such payment must be received within five business days
         after the exercise) and upon receipt by Conexant of any documents
         required pursuant to Section 3(b); and

                  (ii) if a holder of Options elects to pay the exercise price
         of the Option Shares in Shares or in a combination of Shares and cash,
         after full payment of the exercise price (as defined in Section 3(f))
         and personal withholding taxes (if

                                       3
<PAGE>   4
         applicable) is made to Conexant (such payment must be received within
         five business days after the exercise) and upon receipt by Conexant of
         any documents required pursuant to Section 3(b).

                  (iii) A holder of Options (or a person entitled to exercise
         the Options) who chooses to use already-owned Shares to pay all or part
         of the exercise price for the Option Shares to be purchased on exercise
         of any of the Options must deliver to Conexant one or more certificates
         (and executed stock powers), or authorize the book-entry transfer to
         Conexant of shares, representing:

                     -     at least the number of Shares whose value, based on
                           the closing price of Common Stock of Conexant on the
                           NASDAQ reporting system on the day the holder of
                           Options has exercised his or her Options, equals the
                           exercise price for those Option Shares; or

                     -     any lesser number of Shares a holder of Options
                           desires to use to pay the exercise price for those
                           Option Shares and a cheque in the amount of such
                           exercise price less the value of the Shares
                           delivered, based on the closing price of Common Stock
                           of Conexant on the NASDAQ reporting system on the day
                           the Options have been exercised.

                  (iv) Notwithstanding any other provision of this Stock Option
         Agreement, the Secretary of Conexant may limit the number, frequency or
         volume of successive exercises of any of the Options in which payment
         is made, in whole or in part, by delivery of Shares pursuant to this
         subparagraph (c) to prevent unreasonable pyramiding of such exercises.

                  (d) If a holder of Options chooses to pay the exercise price
for the Option Shares to be purchased on exercise of any of the Options entirely
by cash, payment must be made by delivering to Conexant a cheque for, or by wire
transfer of the full amount of the exercise price for those Option Shares.

                  In accordance with Section 3(f), full payment of the exercise
price for the Option Shares purchased must be made within five business days
after the exercise is received by Conexant.

                  (e) Subject to Section 5, a holder of Options may be entitled
to exercise the Options through a cashless exercise (as defined in Section 5).

Shares purchased will be issued as soon as practicable (i) after Conexant has
received full payment therefor or (ii) at Conexant's election in its sole
discretion, after Conexant has received (x) full payment of the exercise price
of those Option Shares and (y) any reimbursement in respect of personal
withholding taxes due pursuant to Section 7. Any certificates for Conexant
Shares issued upon exercise of the Options shall bear a legend stating, among
other things, that the Option Shares issued upon exercise of the Options have
not been registered under the Securities Act of 1933, as amended (the
"Securities Act") and have not been registered or qualified under blue sky or
other securities laws of any state of the United States.

4.       Exercise Procedure After Registration.

                  (a) Following notification by Conexant that the Registration
Statement has been declared effective by the SEC, any holder of Options (or any
other person entitled to exercise the Options) who wishes to exercise all or any

         and speak to a Customer Service Representative);

                  (ii) confirm the Option transaction through the IVR system by
         receiving a confirmation number;

                  (iii) at any time the holder of Options may speak to a

         (ii) in Shares; (iii) in a combination of cash and Shares; or (iv)

                  (v) in the case of an exercise of the Options by any person
         other than the original holder seeking to exercise the Options, such
         documents as ChaseMellon or the Secretary of Conexant may require

         seeking to exercise the Options is entitled to do so.

<PAGE>   6
                  (b) An exercise of the whole or any part of the Options shall
be effective:

                  (i) if a holder of Options elects to pay the exercise price
         for the Option Shares entirely in cash, (i) upon confirmation of the
         transaction by using the IVR system and full payment of the exercise
         price and personal withholding taxes (if applicable) are received by
         ChaseMellon within five business days after the confirmation; and (ii)
         receipt by Conexant of any documents required pursuant to Section
         4(a)(v); and

                  (ii) if a holder of Options elects to pay the exercise price
         of the Option Shares in Shares or in a combination of Shares and cash:
         (i) upon confirmation of the transaction by using the IVR system and

         within five business days following the confirmation; and (ii) receipt
         of any documents required pursuant to Section 4(a)(v).

                  (iii) Once the Registration Statement has been declared
         effective by the SEC, a holder of Options (or a person entitled to
         exercise the Options) who chooses to use already-owned Shares to pay
         all or part of the exercise price for the Option Shares to be purchased
         on exercise of any of the Options must deliver to ChaseMellon one or
         more certificates (and executed stock powers), or authorize the
         book-entry transfer to Conexant of shares, representing:

                    -      at least the number of Shares whose value, based on
                           the closing price of Common Stock of Conexant on the
                           NASDAQ reporting system on the day the holder of
                           Options has exercised his or her Options through the
                           IVR system, equals the exercise price for those
                           Option Shares; or

                    -      any lesser number of Shares a holder of Options
                           desires to use to pay the exercise price for those
                           Option Shares and a cheque in the amount of such
                           exercise price less the value of the Shares
                           delivered, based on the closing price of Common Stock
                           of Conexant on the NASDAQ reporting system on the day
                           the Options have been exercised through the IVR
                           system.

                  (iv) Notwithstanding any other provision of this Stock Option
         Agreement, the Secretary of Conexant may limit the number, frequency or
         volume of successive exercises of any of the Options in which payment
         is made,

                                       6
<PAGE>   7
         in whole or in part, by delivery of Shares pursuant to this
         subparagraph (b) to prevent unreasonable pyramiding of such exercises.

                  (c) If a holder of Options, or other person entitled to
exercise the Options, chooses to pay the exercise price for the Option Shares to
be purchased on exercise of any of the Options entirely in cash, payment must be
made by delivering to ChaseMellon a cheque for the full amount of the exercise
price for those Option Shares, or by wire transfer.

                  In accordance with Section 4(d), full payment of the exercise
price for the Option Shares purchased must be made within five business days
after the exercise has been conducted and confirmed through the IVR system.

                  (d) An exercise conducted and confirmed through the IVR
system, whether or not full payment of the exercise price for the Option Shares
is received by ChaseMellon, shall constitute a binding contractual obligation by
the holder of Options (or any other person entitled to exercise the Options) to
proceed with and complete that exercise of the Options (but only so long as the
holder of Options, or such other person, continues to be entitled to exercise
the Options on that date). By the holder's acceptance of this Stock Option
Agreement, the holder of Options agrees to deliver or cause to be delivered to
ChaseMellon any balance of the exercise price for the Option Shares to be
purchased upon the exercise pursuant to the transaction conducted through the
IVR system required to pay in full the exercise price for those Option Shares,
that payment being (i) in cash, (ii) in Shares, (iii) in a combination of cash
and Shares or (iv) subject to Section 5, by a cashless exercise, on or before
the later of the fifth business day after the date on which the holder of
Options (or any other person entitled to exercise the Options) confirms the
transaction through the IVR system. If such payment is not made, the holder of
Options (and any other person entitled to exercise the Options) authorizes
Conexant, in its discretion, to set off against salary payments or other amounts
due or which may become due the holder of Options (or any other person entitled
to exercise the Options) from Conexant (other than amounts payable under the
Stock Purchase Agreement) any balance of the exercise price for those Option
Shares remaining unpaid thereafter.

                  (e) Subject to Section 5, a holder of Options may be entitled
to exercise the Options through a cashless exercise (as defined in Section 5).

                  (f) A book entry statement or stock certificate representing
the number of Option Shares purchased will be issued as soon as practicable (i)
after ChaseMellon has received full payment therefor or (ii) at Conexant's or
ChaseMellon's election in its

                                       7
<PAGE>   8
sole discretion, after Conexant or ChaseMellon has received (x) full payment of
the exercise price of those Option Shares and (y) any reimbursement in respect
of personal withholding taxes due pursuant to Section 7.

5.       Cashless Exercise.

                  (a)(i) Until the resolutions authorizing the repurchase by
         Conexant of Option Shares described in Section 5(a)(ii) is passed by
         the Board no holder of Options shall be permitted to make a cashless
         exercise.

                  (ii) From and after the effective date of the resolutions of
         the Board of Directors referred to in the immediately following
         sentence, a holder of Options (or any other person entitled to exercise
         the Options) may simultaneously exercise such Options and sell to
         Conexant the number of Option Shares thereby acquired necessary to make
         payment of the exercise price of the Options and any applicable
         personal withholding taxes (a "cashless exercise"). Within 30 days
         after the Closing Date (as defined in the Stock Purchase Agreement),
         the Conexant Board of Directors will pass a resolution authorizing the
         purchase by Conexant of that number of Option Shares issued upon
         exercise of Options, at a price per share equal to the closing price of
         Common Stock on the NASDAQ reporting system on the day the Option is
         exercised, as is necessary so that the proceeds of such purchases would
         be sufficient to pay the exercise price of the Option and any
         applicable personal withholding taxes. From the date on which the Board
         adopts such resolution authorizing the repurchase by Conexant of Option
         Shares until the date on which the Registration Statement has been
         declared effective by the SEC, a holder of Options shall be permitted
         to make a cashless exercise solely by notifying the Conexant Office of
         Stock Administration.

                  (iii) Once Conexant has received notice that the Registration
         Statement has been declared effective by the SEC, a holder of Options
         shall be permitted to make a cashless exercise through ChaseMellon,
         using the IVR system or the Conexant stock program website.

6.       Transferability.

                  (a) The Options and the Option Shares to be issued upon
exercise of the Options have not been registered under the Securities Act of
1933, as amended (the "Securities Act") and have not been registered or
qualified under blue sky or other securities laws of any state of the United
States.

                                       8
<PAGE>   9
                  (b) The Options and the Option Shares to be issued upon
exercise of the Options may not be offered, sold, assigned, pledged,
hypothecated, gifted, encumbered or otherwise disposed of or transferred unless
registered under the Securities Act and any other applicable law of any
jurisdiction, or disposed of pursuant to an exemption from registration. Any
certificates for Conexant Shares issued upon exercise of the Options shall bear
a legend to the foregoing effect. Hedging transactions involving the Conexant
Options may not be conducted unless in compliance with the Securities Act.

                  (c) Pursuant to the Stock Purchase Agreement, Conexant has
agreed to file one or more registration statements under the Securities Act
covering the Option Shares that are issued upon exercise of the Options granted
under the Plan. The Options and the Option Shares have not been registered under
the Securities Act or any applicable U.S. state securities laws and may not be
offered or transferred, sold, assigned, pledged, hypothecated, gifted,
encumbered or otherwise disposed of prior to the date which is two years after
the date of original issue of such Option Shares except (i) to Conexant or any
subsidiary of Conexant or (ii) pursuant to a registration statement which has
been declared effective under the Securities Act or (iii) pursuant to offers and
sales to non-U.S. persons that occur outside the United States in an offshore
transaction within the meaning of Rule 902 of Regulation S under the Securities
Act or (iv) pursuant to Rule 144 under the Securities Act or (v) pursuant to any
other available exemption from the registration requirements of the Securities
Act, if in the opinion of counsel reasonably acceptable to Conexant such
exemption is applicable. No Option Shares and/or Options may be transferred in
violation of the provisions of any applicable U.S. federal or state, United
Kingdom or other jurisdiction's securities laws.

7.       Withholding.

                  Conexant or ChaseMellon shall have the right, in connection
with the exercise of the Options in whole or in part, to deduct from any payment
to be made by Conexant or ChaseMellon under the Plan an amount equal to the
personal taxes required to be withheld by law with respect to such exercise
(including by retaining the notional proceeds received by Conexant on a cashless
exercise of Options by a sale to Conexant or the cash proceeds received by
ChaseMellon from a cashless exercise of Options and remitting the cash or cash
equivalent to Microcosm in order for Microcosm to withhold the applicable
personal taxes in connection with such cashless exercise) or to require the
holder of the Options (or any other person entitled to exercise the Options) to
pay to it an amount sufficient to provide for any such taxes so required to be
withheld. By his or her acceptance of this Stock Option Agreement, the holder of
the Options agrees (for himself or herself and on behalf of any other person who
becomes entitled to exercise the

                                       9
<PAGE>   10
Options) that if Conexant or ChaseMellon elects to require the holder of the
Options (or such other person) to remit an amount sufficient to pay such
personal withholding taxes, the holder of the Options (or such other person)
must remit that amount within five business days after the confirmation of the
Option exercise (Sections 3(f) and 4(d)). If such payment is not made, Conexant,
in its discretion, shall have the same right of set-off with respect to payment
of the personal withholding taxes in connection with the exercise of the Option
as provided under Section 3(f) with respect to payment of the exercise price.

8.       Rights as Shareowner.

                  A holder of Options will not have any rights as a shareowner
with respect to any Option Shares unless and until he or she becomes the holder
of such Option Shares on the books and records of Conexant in accordance with
Section 3(f) or 4(d).

9.       Representations and Warranties.

                  Until the Registration Statement has been declared effective
by the SEC, in connection with the delivery of any Option Shares upon exercise
of an Option, Conexant will have the right to require as a condition of such
delivery that the holder of the Option represent and warrant the following:

                  (a) he or she is an accredited investor as such term is
defined in Rule 501(a) under the Securities Act and is acquiring the Option
Shares issuable upon exercise of the Options for its own account for investment
purposes only and not with a view to, or for sale or resale in connection with,
any public distribution thereof or with any present intention of selling,
distributing or otherwise disposing of any of such shares in violation of the
Securities Act; or

                  (b) he or she is not a U.S. person within the meaning of Rule
902(k) of Regulation S under the Securities Act, which term includes: (i) a

separate entity for federal income tax purposes pursuant to Treasury Regulation

parties agree not to take any action inconsistent with such intended federal

purpose of this Trust as set forth in the introductory sentence of Section 2.03.

         (a) Pursuant to Section 3803(a) of the Business Trust Statute, the
Trust Depositor shall be liable directly to and will indemnify any injured party
or any other creditor of the Trust for all losses, claims, damages, liabilities
and expenses of the Trust to the extent that the Trust Depositor would be liable
if the Trust were a partnership under the Delaware Revised Uniform Limited
Partnership Act in which Trust Depositor were a general partner (including any
New Jersey personal property replacement tax that is imposed on the Trust as a
partnership); provided, however, that Trust Depositor shall not be liable for
any losses incurred by a Certificateholder in the capacity of an investor in the
Trust Certificate or a Noteholder in the capacity of an investor in the Notes.
In addition, any third party creditors of the Trust (other than in connection
with the obligations described in the immediately preceding sentence for which
the Trust Depositor shall not be liable) shall be deemed third party
beneficiaries of this paragraph. The obligations of the Trust Depositor under
this paragraph shall be evidenced by the Trust Certificate described in Section
3.11.

         (b) Other than to the extent set forth in Section 2.07(a), no Owner,
solely by virtue of its being the Holder of the Trust Certificate, shall have
any personal liability for any liability or obligation of the Trust.

         SECTION 2.08. TITLE TO TRUST PROPERTY. Legal title to the Trust Estate
shall be vested at all times in the Trust as a separate legal entity except
where applicable law in any jurisdiction requires title to any part of the Trust
Estate to be vested in an Owner Trustee or Owner Trustees, in which case title
shall be deemed to be vested in the Owner Trustee, a co-trustee and/or a
separate trustee, as the case may be.

         SECTION 2.09. SITUS OF TRUST. The Trust will be located and
administered in the State of Delaware or the State of Illinois. All bank
accounts maintained by the Owner Trustee on behalf of the Trust shall be located

employees in any state other than Delaware;

                                      -7-
<PAGE>   13

provided, however, that nothing herein shall restrict or prohibit the Owner
Trustee from having employees within or without the State of Delaware. Payments
will be received by the Trust only in Delaware or Illinois and payments will be
made by the Trust only from Delaware or Illinois. The only office of the Trust
will be at the Owner Trustee Corporate Trust Office.

         SECTION 2.10. REPRESENTATIONS AND WARRANTIES OF THE TRUST DEPOSITOR.

         The Trust Depositor hereby represents and warrants to the Owner Trustee
that:

         (i)      The Trust Depositor is duly organized and validly existing as
                  a corporation organized and existing and in good standing
                  under the laws of the State of Delaware, with power and
                  authority to own its properties and to conduct its business
                  and had at all relevant times, and has, power, authority and
                  legal right to acquire and own the Contracts.

         (ii)     The Trust Depositor is duly qualified to do business as a
                  foreign corporation in good standing and has obtained all
                  necessary licenses and approvals in all jurisdictions in which
                  the ownership or lease of property or the conduct of its
                  business requires such qualifications.

         (iii)    The Trust Depositor has the power and authority to execute and
                  deliver this Agreement and to carry out its terms; the Trust
                  Depositor has full power and authority to sell and assign the
                  property to be sold and assigned to and deposited with the
                  Owner Trustee on behalf of the Trust as part of the Trust
                  Estate and has duly authorized such sale and assignment and
                  deposit with the Owner Trustee on behalf of the Trust by all
                  necessary corporate action; and the execution, delivery and
                  performance of this Agreement have been duly authorized by the
                  Trust Depositor by all necessary corporate action. This
                  Agreement constitutes the legal, valid and binding obligation
                  of the Trust Depositor and is enforceable in accordance with
                  its terms, except as enforcement of such terms may be limited
                  by bankruptcy, insolvency or similar laws affecting the
                  enforcement of creditors' rights generally and by the
                  availability of equitable remedies.

         (iv)     The consummation of the transactions contemplated by this
                  Agreement and the fulfillment of the terms hereof do not
                  conflict with, result in any breach of any of the terms and
                  provisions of, nor constitute (with or without notice or lapse
                  of time) a default under, the articles of incorporation or
                  bylaws of the Trust Depositor, or any indenture, agreement or
                  other instrument to which the Trust Depositor is a party or

                                      -8-
<PAGE>   14

                  by which it is bound; nor result in the creation or imposition
                  of any Lien upon any of the properties of the Trust Depositor
                  pursuant to the terms of any such indenture, agreement or
                  other instrument (other than pursuant to the Transaction
                  Documents); nor violate any law or any order, rule or
                  regulation applicable to the Trust Depositor of any court or
                  of any federal or state regulatory body, administrative agency
                  or other governmental instrumentality having jurisdiction over
                  the Trust Depositor or its properties.

         (v)      All approvals, authorizations, consents, orders or other
                  actions of any person or any governmental entity required in
                  connection with the execution and delivery of this Agreement
                  and the fulfillment of the terms hereof have been obtained.

         (vi)     There are no proceedings or investigations pending, or to the
                  Trust Depositor's best knowledge threatened, before any court,
                  regulatory body, administrative agency or other governmental
                  instrumentality having jurisdiction over the Trust Depositor
                  or its properties: (A) asserting the invalidity of this
                  Agreement, any of the other Transaction Documents or the Trust
                  Certificate, (B) seeking to prevent the issuance of the Trust
                  Certificate or the consummation of any of the transactions
                  contemplated by this Agreement or any of the other Transaction
                  Documents, (C) seeking any determination or ruling that might
                  materially and adversely affect the performance by the Trust
                  Depositor of its obligations under, or the validity or
                  enforceability of, this Agreement, any of the other
                  Transaction Documents or the Trust Certificate or (D)
                  involving the Trust Depositor and which might adversely affect
                  the federal income tax or other federal, state or local tax
                  attributes of the Trust Certificate.

         SECTION 2.11. FEDERAL INCOME TAX TREATMENT. It is the intention of the
Trust Depositor that the Trust be disregarded as a separate entity for federal
income tax purposes pursuant to Treasury Regulations Section
301.7701-3(b)(1)(ii) as in effect for periods after January 1, 1997. The Trust
Certificate constitutes the sole equity interest in the Trust and must at all
times be held by either the Trust Depositor or its transferee as sole owner. The
Trust Depositor agrees not to take any action inconsistent with such intended
federal income tax treatment. Because for federal income tax purposes the Trust
will be disregarded as a separate entity, Trust items of income, gain, loss and
deduction for any month as determined for federal income tax purposes shall be
allocated entirely to the Trust Depositor (or subsequent purchaser of the Trust
Certificate) as the sole Certificateholder.

realized losses and (ii) any litigation with claims in excess of $1,000,000 to

immediately following the commencement of such litigation and continuing until

has resulted in a final judgment against the Trust Depositor, such judgment has
been satisfied), the Trust Depositor shall not pay any dividend to OCAI, or make
any distribution on or in respect of its capital stock to OCAI, or repay the
principal amount of any indebtedness of the Trust Depositor held by OCAI, unless
(i) after giving effect to such payment, distribution or repayment, the Trust
Depositor's liquid assets shall not be less than the amount of actual damages
claimed in such litigation or (ii) the Rating Agencies shall not downgrade the
then existing rating on the Certificate with respect to any such payment,
distribution or repayment;

         (b) it shall not, for any reason, institute proceedings for the Trust

seeking or consenting to reorganization or relief under any applicable federal
or state law relating to the bankruptcy of the Trust, or consent to the
appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other
similar official) of the Trust or a substantial part of the property of the

engage in any business, except, in each case, as permitted by its articles of
incorporation, by-laws and the Transaction Documents;

such counterparty that prior to the occurrence of the event specified in Section
9.01(e) such counterparty shall not institute against, or join any other Person
in instituting against, it or the Trust, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings or other similar proceedings
under the laws of the United States or any state of the United States; and

                                      -10-
<PAGE>   16

         (e) it shall not, for any reason, withdraw or attempt to withdraw from
this Agreement, dissolve, institute proceedings for it to be adjudicated a
bankrupt or insolvent, or consent to the institution of bankruptcy or insolvency
proceedings against it, or file a petition seeking or consenting to
reorganization or relief under any applicable federal or state law relating to
bankruptcy, or consent to the appointment of a receiver, liquidator, assignee,
trustee, sequestrator (or other similar official) of it or a substantial part of
its property, or make any assignment for the benefit of creditors, or admit in
writing its inability to pay its debts generally as they become due, or declare
or effect a moratorium on its debt or take any action in furtherance of any such

         (b) No transfer of the Trust Certificate shall be made unless such
transfer is made in a transaction which does not require registration or
qualification under the Securities Act of 1933 or qualification under any state
securities or "Blue Sky" laws. Neither the Owner Trustee nor the Certificate
Registrar shall effect the registration of any transfer of the Trust Certificate
unless, (i) prior to such transfer the Owner Trustee shall have received a Tax
Opinion, and (ii) following such transfer, there would be no more than one
Holder of the Trust Certificate and the Holder of the Trust Certificate would
not be a Foreign Person, a partnership, Subchapter S corporation or grantor
trust.

         SECTION 3.02. THE TRUST CERTIFICATE. The Trust Certificate shall be
substantially in the form of Exhibit B hereto. The Trust Certificate shall be
issued in an amount equal to the Certificate Balance. The Trust Certificate
shall be executed by the Owner Trustee on behalf of the Trust by manual or
facsimile signature of an authorized officer of the Owner Trustee and shall be
deemed to have been validly issued when so executed. The Trust Certificate
bearing the manual or facsimile signature of individuals who were, at the time
when such signatures were affixed, authorized to sign on behalf of the Owner
Trustee shall be a valid and binding obligation of the Trust, notwithstanding
that such individuals or any of them have ceased to be so authorized prior to
the authentication and delivery of such Trust Certificate or did not hold such
offices at the date of such Trust Certificate. The Trust Certificate shall be
dated the date of its authentication.

Trustee of the Contract Files and the other Trust Assets, a Trust Certificate

authentication substantially in the form set forth in the form of Trust
Certificate attached hereto as Exhibit B, executed by the Owner Trustee or its
authenticating agent, by manual signature, and such certificate upon any Trust
Certificate shall be conclusive evidence, and the only evidence, that such Trust
Certificate has been duly authenticated and delivered hereunder. Upon issuance,

Certificate Register, subject to such reasonable regulations as it may
prescribe. The Certificate Register shall provide for the registration of the
Trust Certificate and transfers and exchanges of the Trust Certificate as

         (c) Every Trust Certificate presented or surrendered for registration
of transfer shall be accompanied by a written instrument of transfer in form
satisfactory to the Owner Trustee and the Certificate Registrar duly executed by
the Holder thereof or his attorney duly authorized in writing.

         (d) No service charge shall be made for any registration of transfer or
exchange of the Trust Certificate, but the Owner 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 the Trust Certificate.

         (e) All Trust Certificates surrendered for registration of transfer
shall be canceled and subsequently destroyed by the Owner Trustee.

         SECTION 3.05. MUTILATED, DESTROYED, LOST OR STOLEN TRUST CERTIFICATES.
If (i) any mutilated Trust Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Trust Certificate, and (ii) there is
delivered to the Certificate Registrar and the Owner Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice that such Trust Certificate has been acquired by a bona fide
purchaser, the Owner Trustee on behalf of the Trust shall execute and the Owner
Trustee or its authenticating agent shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Trust
Certificate, a new Trust Certificate of like tenor and fractional undivided
interest. In connection with the issuance of any new Trust Certificate under
this Section, the Owner Trustee may require the payment by the Holder of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto. Any duplicate Trust Certificate issued pursuant to this
Section shall constitute complete and indefeasible evidence of ownership in the
Trust, as if originally issued, whether or not the lost, stolen or destroyed
Trust Certificate shall be found at any time.

         SECTION 3.06. PERSONS DEEMED OWNERS. Prior to due presentation of a
Trust Certificate for registration of transfer, the Owner Trustee, the
Certificate Registrar and any of their respective agents may treat the Person in
whose name any Trust Certificate is registered as the owner of such Trust
Certificate for the purpose of receiving distributions pursuant to Section 5.02
and for all other purposes whatsoever, and none of the Owner Trustee, the
Certificate Registrar, any Paying Agent or any of their respective agents shall
be affected by any notice of the contrary.

         SECTION 3.07. ACCESS TO LIST OF CERTIFICATEHOLDER'S NAME AND ADDRESSES.
The Owner Trustee shall furnish or cause to be furnished to the Servicer and the
Trust Depositor, within 15 days after receipt by the Certificate Registrar of a
written request therefor from the Servicer or the Trust Depositor, the name and
address of the Certificate-

                                      -13-
<PAGE>   19

holder as of the most recent Record Date in such form as the Servicer or the
Trust Depositor may reasonably require. Every Certificateholder, by receiving
and holding a Trust Certificate, agrees with the Servicer, the Trust Depositor
and the Owner Trustee that none of the Servicer, the Trust Depositor or the
Owner Trustee shall be held accountable by reason of the disclosure of any such
information as to the name and address of the Certificateholder hereunder,
regardless of the source from which such information was derived.

         SECTION 3.08. MAINTENANCE OF OFFICE OR AGENCY. The Owner Trustee shall
maintain in Delaware, an office or offices or agency or agencies where the Trust
Certificate may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Owner Trustee in respect of the Trust
Certificate and this Agreement may be served. The Owner Trustee hereby
designates the Owner Trustee Corporate Trust Office as its office for such
purposes. The Owner Trustee shall give prompt written notice to the Trust
Depositor, the Servicer and to the Certificateholder of any change in the
location of the Certificate Register or any such office or agency.

         SECTION 3.09. TEMPORARY TRUST CERTIFICATE. Pending the preparation of
the definitive fully registered Trust Certificate (the "Definitive Trust
Certificate"), the Owner Trustee, on behalf of the Trust, may execute,
authenticate and deliver, a temporary Trust Certificate that is printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the Definitive Trust Certificate in
lieu of which it is issued. If a temporary Trust Certificate is issued, the
Trust Depositor will cause the Definitive Trust Certificate to be prepared
without unreasonable delay. After the preparation of the Definitive Trust
Certificate, the temporary Trust Certificate shall be exchangeable for the
Definitive Trust Certificate upon surrender of the temporary Trust Certificate
at the office or agency to be maintained as provided in Section 3.08, without
charge to the Holder. Upon surrender for cancellation of the temporary Trust
Certificate, the Owner Trustee shall execute and authenticate and deliver in
exchange therefor a like principal amount of the Definitive Trust Certificate.
Until so exchanged, the temporary Trust Certificate shall in all respects be
entitled to the same benefits hereunder as a Definitive Trust Certificate.

         SECTION 3.10. APPOINTMENT OF PAYING AGENT. The Paying Agent shall make
distributions to the Certificateholder from the Certificate Distribution Account
pursuant to Section 5.02(a) and shall report the amounts of such distributions
to the Owner Trustee. Any Paying Agent shall have the revocable power to
withdraw funds from the Certificate Distribution Account for the purpose of
making the distributions referred to above. The Owner Trustee may revoke such
power and remove the Paying Agent if the Owner Trustee determines in its sole
discretion that the Paying Agent shall have failed to perform its obligations
under this Agreement in any material respect. The Paying Agent initially shall
be Harris Trust and Savings Bank, and any co-paying agent chosen by the

                                      -14-
<PAGE>   20

Paying Agent that is acceptable to the Owner Trustee. Each Paying Agent shall be
permitted to resign as Paying Agent upon 30 days' written notice to the Owner
Trustee. In the event that Harris Trust and Savings Bank shall no longer be the
Paying Agent, the Owner Trustee shall appoint a successor to act as Paying Agent
(which shall be a bank or trust company). The Owner Trustee shall cause such
successor Paying Agent or any additional Paying Agent appointed by the Owner
Trustee to execute and deliver to the Owner Trustee an instrument in which such
successor Paying Agent or additional Paying Agent shall agree with the Owner
Trustee that, as Paying Agent, such successor Paying Agent or additional Paying
Agent will hold all sums, if any, held by it for payment to the
Certificateholder in trust for the benefit of the Certificateholder entitled
thereto until such sums shall be paid to such Certificateholder. The Paying
Agent shall return all unclaimed funds to the Owner Trustee and upon removal of
a Paying Agent such Paying Agent shall also return all funds in its possession
to the Owner Trustee. The provisions of Sections 7.01, 7.03, 7.04 and 8.01 shall
apply to the Owner Trustee also in its role as Paying Agent, for so long as the
Owner Trustee shall act as Paying Agent and, to the extent applicable, to any
other paying agent appointed hereunder. Any reference in this Agreement to the
Paying Agent shall include any co-paying agent unless the context requires
otherwise.

         SECTION 3.11. OWNERSHIP BY TRUST DEPOSITOR OF TRUST CERTIFICATE. Trust
Depositor shall on the Closing Date purchase from the Trust a Trust Certificate
representing the Certificate Balance.

                  lawsuit brought by or against the Trust (except with respect

                  the interest of the Owner;

         (e)      the amendment, change or modification of the Administration
                  Agreement, except to cure any ambiguity or to amend or
                  supplement any provision in a manner or add any provision that
                  would not materially and adversely affect the interests of the
                  Owner; or

         (f)      the appointment pursuant to the Indenture of a successor Note
                  Registrar, Paying Agent or Indenture Trustee or pursuant to
                  this Agreement of a successor Certificate Registrar, or the

the preceding sentence only upon written instructions signed by the Owner.

         SECTION 4.03. ACTION BY OWNER WITH RESPECT TO BANKRUPTCY. Subject to
Section 2.12(b), the Owner Trustee shall not have the power to commence a

         SECTION 4.04. RESTRICTIONS ON OWNER'S POWER. The Owner shall not direct
the Owner Trustee to take or to refrain from taking any action if such action or
inaction would be contrary to any obligation of the Trust or the Owner Trustee

                                  ARTICLE FIVE

                           APPLICATION OF TRUST FUNDS;
                                 CERTAIN DUTIES

         SECTION 5.01. ESTABLISHMENT OF TRUST ACCOUNT. The Owner Trustee, for
the benefit of the Certificateholder, shall establish and maintain in the name
of the Trust an Eligible Account (the "Certificate Distribution Account"),
bearing a designation clearly indicating that the funds deposited therein are
held for the benefit of the Certificateholder.

         The Owner Trustee shall possess all right, title and interest in all
funds on deposit from time to time in the Certificate Distribution Account and
in all proceeds thereof. Except as otherwise expressly provided herein, the
Certificate Distribution Account shall be under the sole dominion and control of
the Owner Trustee for the benefit of the Certificateholder. If, at any time, the
Certificate Distribution Account ceases to be an Eligible Account, the Owner
Trustee (or the Trust Depositor on behalf of the Owner Trustee, if the
Certificate Distribution Account is not then held by the Owner Trustee or an
Affiliate thereof) shall within ten Business Days (or such longer period, not to
exceed 30 calendar days, as to which each Rating Agency may consent) establish a

         SECTION 5.02. APPLICATION OF TRUST FUNDS.

<PAGE>   23

         (c) In the event that any withholding tax is imposed on the Trust's
payment (or allocation of income) to the Certificateholder, such tax shall
reduce the amount otherwise distributable to the Certificateholder in accordance
with this Section. The Paying Agent is hereby authorized and directed to retain
from amounts otherwise distributable to the Owner sufficient funds for the
payment of any tax that is legally owed by the Trust (but such authorization
shall not prevent the Owner Trustee from contesting any such tax in appropriate
proceedings, and withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings). The amount of any withholding tax imposed with
respect to the Certificateholder shall be treated as cash distributed to such
Certificateholder at the time it is withheld by the Trust and remitted to the
appropriate taxing authority. If there is a possibility that withholding tax is
payable with respect to a distribution, the Paying Agent may in its sole
discretion withhold such amounts in accordance with this paragraph (c).

the final payment upon retirement of the Certificate, distributions required to

Certificateholder appearing in the Certificate Register.

         SECTION 5.04. NO SEGREGATION OF MONEYS; NO INTEREST. Subject to
Sections 5.01 and 5.02, moneys received by the Owner Trustee hereunder need not
be segregated in any manner except to the extent required by law or the Transfer
and Servicing Agreement and may be deposited under such general conditions as
may be prescribed by law, and the Owner Trustee shall not be liable for any
interest thereon.

         SECTION 5.05. ACCOUNTING AND REPORTS TO THE CERTIFICATEHOLDER, THE
INTERNAL REVENUE SERVICE AND OTHERS. The Administrator shall (a) maintain (or
cause to be maintained) the books of the Trust on a fiscal year basis that is
consistent with the fiscal year basis used by the Originator and on a cash basis
method of accounting, (b) deliver to the Owner, as may be required by the Code
and applicable Treasury Regulations, such information as may be required to
enable the Owner to prepare its federal and state income tax returns, (c) file
such tax returns relating to the Trust and make such elections as from time to
time may be required or appropriate under any applicable state or federal
statute or any rule or regulation thereunder so as to maintain the federal
income tax treatment for the Trust as set forth in Section 2.11, (d) cause such
tax returns to be signed in the manner required by law and (e) collect or cause
to be collected any withholding tax as described in and in accordance with
Section 5.02(c) with respect to income or distributions to Owner. The Owner
Trustee shall elect under Section 1278 of the Code to include in income

applicable, the Owner Trustee shall not make the election provided under Section
754 or Section 761 of the Code.

                      AUTHORITY AND DUTIES OF OWNER TRUSTEE

         SECTION 6.01. GENERAL AUTHORITY. Subject to the provisions and
limitations of Sections 2.03 and 2.06, the Owner Trustee is authorized and
directed to execute and deliver the Transaction Documents to which the Trust is
to be a party and each certificate or other document attached as an exhibit to
or contemplated by the Transaction Documents to which the Trust is to be a party
and any amendment or other agreement, as evidenced conclusively by the Owner
Trustee's execution thereof. In addition to the foregoing, the Owner Trustee is
authorized, but shall not be obligated, to take all actions required of the
Trust pursuant to the Transaction Documents. The Owner Trustee is further
authorized from time to time to take such action as the Administrator recommends
with respect to the Transaction Documents.

         SECTION 6.02. GENERAL DUTIES. Subject to the provisions and limitations
of Sections 2.03 and 2.06, it shall be the duty of the Owner Trustee to
discharge (or cause to be discharged through the Administrator) all of its
responsibilities pursuant to the terms of this Agreement and the Transaction
Documents to which the Trust is a party and under which it has expressly assumed
any responsibility and to administer the Trust in the interest of the Owner,
subject to the Transaction Documents and in accordance with the provisions of
this Agreement. Without limiting the foregoing, the Owner Trustee shall on
behalf of the Trust file and prove any claim or claims that may exist against
OCAI in connection with any claims paying procedure as part of an insolvency or
receivership proceeding involving OCAI. Notwithstanding the foregoing, the Owner
Trustee shall be deemed to have discharged its duties and responsibilities
hereunder and under the Transaction Documents to the extent the Administrator
has agreed in the Administration Agreement to perform any act or to discharge
any duty of the Owner Trustee hereunder or under any Transaction Document, and
the Owner Trustee shall not be held liable for the default or failure of the
Administrator to carry out its obligations under the Administration Agreement.

<PAGE>   25

         SECTION 6.03.  ACTION UPON INSTRUCTION.

         (a) Subject to Article Four, in accordance with the terms of the
Transaction Documents the Owner may by written instruction direct the Owner
Trustee in the management of the Trust.

         (b) The Owner Trustee shall not be required to take any action
hereunder or under any other Transaction Document if the Owner Trustee shall
have reasonably determined, or shall have been advised by counsel, that such
action is likely to result in liability on the part of the Owner Trustee or is
contrary to the terms hereof or of any other Transaction Document or is
otherwise contrary to law.

         (c) Whenever the Owner Trustee is unable to decide between alternative
courses of action permitted or required by the terms of this Agreement or under
any other Transaction Document, the Owner Trustee shall promptly give notice (in
such form as shall be appropriate under the circumstances) to the Owner
requesting instruction as to the course of action to be adopted, and to the
extent the Owner Trustee acts in good faith in accordance with any written
instruction of the Owner received, the Owner Trustee shall not be liable on
account of such action to any Person. If the Owner Trustee shall not have
received appropriate instruction within ten days of such notice (or within such
shorter period of time as reasonably may be specified in such notice or may be
necessary under the circumstances) it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Agreement and the
other Transaction Documents, as it shall deem to be in the best interests of the
Owner, and shall have no liability to any Person for such action or inaction.

         (d) In the event that the Owner Trustee is unsure as to the
applicability of any provision of this Agreement or any other Transaction
Document or any such provision is ambiguous as to its application, or is, or
appears to be, in conflict with any other applicable provision, or in the event
that this Agreement permits any determination by the Owner Trustee or is silent
or incomplete as to the course of action that the Owner Trustee is required to
take with respect to a particular set of facts, the Owner Trustee may give
notice (in such form as shall be appropriate under the circumstances) to the
Owner requesting instruction and, to the extent that the Owner Trustee acts or
refrains from acting in good faith in accordance with any such instruction
received, the Owner Trustee shall not be liable, on account of such action or
inaction, to any Person. If the Owner Trustee shall not have received
appropriate instruction within ten days of such notice (or within such shorter
period of time as reasonably may be specified in such notice or may be necessary
under the circumstances) it may, but shall be under no duty to, take or refrain
from taking such action not inconsistent with this Agreement or the other
Transaction Documents, as it shall deem to be in the best interests of the
Owner, and shall have no liability to any Person for such action or inaction.

<PAGE>   26

         (e) Notwithstanding anything contained herein to the contrary, the
Owner Trustee shall not be required to take any action in any jurisdiction other
than in the State of Delaware if the taking of such action will (i) require the
registration with, licensing by or the taking of any other similar action in
respect of, any state or other governmental authority or agency of any
jurisdiction other than the State of Delaware by or with respect to the Owner
Trustee; (ii) result in any fee, tax or other governmental charge under the laws
of any jurisdiction or any political subdivisions thereof in existence on the
date hereof other than the State of Delaware being payable by the Owner Trustee;
or (iii) subject the Owner Trustee to personal jurisdiction in any jurisdiction
other than the State of Delaware for causes of action arising from acts
unrelated to the consummation of the transactions by the Owner Trustee
contemplated in this Agreement. In the event that the Owner Trustee has
determined that any action set forth in clauses (i)-(iii) will result in the
consequences stated therein, the Administrator and the Owner Trustee shall
appoint one or more Persons to act as co-trustee pursuant to Section 10.05.

         SECTION 6.04. NO DUTIES EXCEPT AS SPECIFIED IN THIS AGREEMENT OR IN
INSTRUCTIONS. The Owner Trustee shall not have any duty or obligation to manage,
make any payment with respect to, register, record, sell, dispose of or
otherwise deal with the Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any document contemplated hereby
to which the Owner Trustee is a party, except as expressly provided by the terms
of this Agreement or any document or written instruction received by the Owner
Trustee pursuant to Section 6.03; and no implied duties or obligations shall be
read into this Agreement or any other Transaction Document against the Owner
Trustee. The Owner Trustee shall have no responsibility for filing any financing
or continuation statement in any public office at any time or to otherwise
perfect or maintain the perfection of any security interest or lien granted to
it hereunder or to prepare or file any Commission filing for the Trust or to
record this Agreement or any other Transaction Document, which shall be the
responsibility of the Administrator pursuant to the Administration Agreement.
The Owner Trustee nevertheless agrees that it will, at its own cost and expense,
promptly take all action as may be necessary to discharge any liens on any part
of the Trust Estate that result from actions by, or claims against, the Owner
Trustee in its individual capacity that are not related to the ownership or the
administration of the Trust Estate.

         SECTION 6.05. NO ACTION EXCEPT UNDER SPECIFIED DOCUMENTS OR
INSTRUCTIONS. The Owner Trustee shall not manage, control, use, sell, dispose of
or otherwise deal with any part of the Trust Estate except (i) in accordance
with the powers granted to and the authority conferred upon the Owner Trustee

Documents and (iii) in accordance with any document or instruction delivered to
the Owner Trustee pursuant to Section 6.03.

         SECTION 6.06. RESTRICTIONS. The Owner Trustee shall not take any action
(i) that is inconsistent with the purposes of the Trust set forth in Section
2.03 or (ii) that, to the actual knowledge of a Responsible Officer of the Owner
Trustee, would result in the Trust's becoming taxable as a corporation for
federal or state income tax purposes. The Owner shall not direct the Owner
Trustee to take actions that would violate the provisions of this Section.

                                  ARTICLE SEVEN

                          CONCERNING THE OWNER TRUSTEE

         SECTION 7.01. ACCEPTANCE OF TRUSTS AND DUTIES. The Owner Trustee
accepts the trusts hereby created and agrees to perform its duties hereunder
with respect to such trusts but only upon the terms of this Agreement. The Owner
Trustee also agrees to disburse all moneys actually received by it constituting
part of the Trust Estate upon the terms of the Transaction Documents and this
Agreement. The Owner Trustee shall not be answerable or accountable hereunder or
under any other Transaction Document under any circumstances, except (i) for its
own willful misconduct or gross negligence or (ii) in the case of the inaccuracy
of any representation or warranty contained in Section 7.03 expressly made by
the Owner Trustee in its individual capacity. In particular, but not by way of
limitation (and subject to the exceptions set forth in the preceding sentence):

         (a)      the Owner Trustee shall not be liable for any error of
                  judgment made by a responsible officer of the Owner Trustee
                  which did not result from gross negligence on the part of such
                  responsible officer;

         (b)      the Owner Trustee shall not be liable with respect to any
                  action taken or omitted to be taken by it in accordance with
                  the instructions of the Administrator or any Owner;

         (c)      no provision of this Agreement or any other Transaction
                  Document shall require the Owner Trustee to expend or risk
                  funds or otherwise incur any financial liability in the
                  performance of any of its rights or powers hereunder or under
                  any Transaction Document if the Owner Trustee shall have
                  reasonable grounds for believing that repayment of such funds

         SECTION 7.03. REPRESENTATIONS AND WARRANTIES. The Owner Trustee hereby
represents and warrants to the Trust Depositor and the Owner that:

         (a)      It is a banking corporation duly organized and validly
                  existing in good standing under the laws of the State of
                  Delaware. It has all requisite corporate power and authority
                  to execute, deliver and perform its obligations under this
                  Agreement.

         (b)      It has taken all corporate action necessary to authorize the
                  execution and delivery by it of this Agreement, and this
                  Agreement will be executed and delivered by one of its
                  officers who is duly authorized to execute and deliver this
                  Agreement on its behalf.

         (c)      Neither the execution nor the delivery by it of this
                  Agreement, nor the consummation by it of the transactions
                  contemplated hereby nor compliance by it with any of the terms
                  or provisions hereof will contravene any federal or Delaware
                  law, governmental rule or regulation governing the banking or
                  trust powers of the Owner Trustee or any judgment or order
                  binding on it, or constitute any default under its charter
                  documents or bylaws or any indenture, mortgage, contract,
                  agreement or instrument to which it is a party or by which any
                  of its properties may be bound or result in the creation or
                  imposition of any lien, charge or encumbrance on the Trust
                  Estate resulting from actions by or claims against the Owner
                  Trustee individually which are unrelated to this Agreement or
                  the other Transaction Documents.

         SECTION 7.04. RELIANCE; ADVICE OF COUNSEL.

         (a) The Owner Trustee shall incur no liability to anyone in acting upon
any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties. The
Owner Trustee may accept a certified copy of a resolution of the board of
directors or other governing body of any corporate party as conclusive evidence
that such resolution has been duly adopted by such body and that the same is in
full force and effect. As to any fact or matter the method of determination of
which is not specifically prescribed herein, the Owner Trustee may for all
purposes hereof rely on a certificate, signed by the president or any vice
president or by the treasurer or other authorized officers of the relevant
party, as to such fact or matter and such certificate shall constitute full
protection to the Owner Trustee for any action taken or omitted to be taken by
it in good faith in reliance thereon.

         (b) In the exercise or administration of the trusts hereunder and in
the performance of its duties and obligations under this Agreement or the other
Transaction Documents, the Owner Trustee (i) may, at the expense of the Trust
Depositor, act directly or through its agents or attorneys pursuant to
agreements entered into by any of them, and the Owner Trustee shall not be
liable for the conduct or misconduct of such agents or attorneys as shall have
been selected by the Owner Trustee with reasonable care, and (ii) may, at the
expense of the Trust Depositor, consult with counsel, accountants and other
skilled persons to be selected with reasonable care and employed by it. The
Owner Trustee shall not be liable for anything done, suffered or omitted in good
faith by it in accordance with the written opinion or advice of any such
counsel, accountants or other such persons.

         SECTION 7.05. NOT ACTING IN INDIVIDUAL CAPACITY. Except as provided in
this Article Seven, in accepting the trusts hereby created, The Bank of New York
(Delaware) acts solely as Owner Trustee hereunder and not in its individual
capacity, and all Persons having any claim against the Owner Trustee by reason
of the transactions contemplated by this Agreement or any other Transaction
Document shall look only to the Trust Estate for payment or satisfaction
thereof.

         SECTION 7.06. OWNER TRUSTEE NOT LIABLE FOR TRUST CERTIFICATE, NOTES OR
CONTRACTS. The recitals contained herein and in the Trust Certificate (other
than the signature and countersignature of the Owner Trustee and the certificate
of authentication on the Trust Certificate) shall be taken as the statements of
the Trust Depositor, and the Owner Trustee assumes no responsibility for the
correctness thereof. The Owner Trustee makes no representations as to the
validity or sufficiency of this Agreement, any other Transaction Document or the
Trust Certificate (other than the signature and countersignature of the Owner
Trustee and the certificate of authentication on the Trust Certificate) or the
Notes, or of any Contract or related documents. The Owner Trustee shall at no
time have any responsibility or liability for or with respect to the legality,
validity and enforceability of any Contract, or the perfection and priority of
any security interest created by any Contract in any Equipment or the
maintenance of any such perfection and priority, or for or with respect to the
sufficiency of the Trust Estate or its ability to generate the payments to be
distributed to the Certificateholder under this Agreement or the Noteholders
under the Indenture, including, without limitation, the existence, condition and
ownership of any Equipment; the existence and enforceability of any insurance
thereon; the existence and contents of any Contract on any computer or other

or in any related document or the accuracy of any such warranty or
representation; or any action of the

                                      -25-

Administrator, the Indenture Trustee or the Servicer or any subservicer taken in
the name of the Owner Trustee.

         SECTION 7.07. OWNER TRUSTEE MAY OWN TRUST CERTIFICATE AND NOTES. The
Owner Trustee in its individual or any other capacity may become the owner or
pledgee of the Trust Certificate or Notes and may deal with the Trust Depositor,
the Administrator, the Indenture Trustee and the Servicer in banking
transactions with the same rights as it would have if it were not Owner Trustee.

primary obligor for, and shall indemnify the Owner Trustee and its successors,
assigns and servants (collectively, the "Indemnified Parties") from and against,
any and all liabilities, obligations, losses, damages, taxes, claims, actions
and suits, and any and all reasonable costs, expenses and disbursements
(including reasonable legal fees and expenses) of any kind and nature whatsoever
(collectively, "Expenses") which may at any time be imposed on, incurred by or
asserted against the Owner Trustee or any Indemnified Party in any way relating
to or arising out of this Agreement, the other Transaction Documents, the Trust
Estate, the administration of the Trust Estate or the action or inaction of the
Owner Trustee hereunder, except only that the Trust Depositor shall not be
liable for or required to indemnify an Indemnified Party from and against
Expenses arising or resulting from any of the matters described in the third
sentence of Section 7.01. The indemnities contained in this Section shall
survive the resignation or termination of the Owner Trustee or the termination
of this Agreement. In the event of any claim, action or proceeding for which
indemnity will be sought pursuant to this Section, the Owner Trustee's choice of
legal counsel shall be subject to the approval of the Trust Depositor, which

                         TERMINATION OF TRUST AGREEMENT

         SECTION 9.01. TERMINATION OF TRUST AGREEMENT.

         (a) This Trust shall dissolve upon the earlier of (i) the day following
the final distribution by the Owner Trustee of all moneys or other property or
proceeds of the Trust Estate in accordance with the terms of the Indenture, the
Transfer and Servicing Agreement and Article Five, provided that the Trust
Depositor shall have delivered a written notice to the Owner Trustee electing
to terminate the Trust, and (ii) the time provided in Section 9.02. The
bankruptcy, liquidation, dissolution, death or incapacity of any Owner, other
than the Trust Depositor as described in Section 9.02, shall not (i) operate to
terminate this Agreement or the Trust, (ii) entitle such Owner's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of all or any part of the
Trust or Trust Estate or (iii) otherwise affect the rights, obligations and
liabilities of the parties hereto.

Date upon which the Certificateholder shall surrender its Trust Certificate to
the Paying Agent for payment of the final distribution and cancellation, shall
be given by the Owner Trustee by letter to the Certificateholder mailed within
five Business Days of receipt of notice of termination from the Servicer given

the Distribution Date upon or with respect to which final payment of the Trust
Certificate shall be made upon presentation and surrender of the Trust

amount of any such final payment and (iii) that the Record Date otherwise
applicable to such Distribution Date is not applicable, payments being made only

distributed to the Certificateholder amounts distributable on such Distribution
Date pursuant to Section 5.02.

<PAGE>   33

         (d) In the event that the Certificateholder shall not surrender its
Trust Certificate for cancellation within six months after the date specified in
the above mentioned written notice, the Owner Trustee shall give a second
written notice to such Certificateholder to surrender its Trust Certificate for
cancellation and receive the final distribution with respect thereto. If within
one year after the second notice the Trust Certificate shall not have been
surrendered for cancellation, the Owner Trustee may take appropriate steps, or
may appoint an agent to take appropriate steps, to contact the Certificateholder
concerning surrender of its Trust Certificates, and the cost thereof shall be
paid out of the funds and other assets that shall remain subject to this
Agreement. Any funds remaining in the Trust after exhaustion of such remedies
shall be distributed by the Owner Trustee to the Trust Depositor.

         (e) Upon the winding up of the Trust and payment of all liabilities in
accordance with Section 3808 of the Business Trust Statute, the Owner Trustee
shall cause the Certificate of Trust to be canceled by filing a certificate of
cancellation with the Secretary of State in accordance with the provisions of
Section 3810 of the Business Trust Statute at which time the Trust shall
terminate. The Administrator shall be the liquidator of the Trust.

         SECTION 9.02. DISSOLUTION UPON BANKRUPTCY OF TRUST DEPOSITOR OR
WITHDRAWAL OR REMOVAL OF TRUST DEPOSITOR. In the event that an Insolvency Event
shall occur with respect to the Trust Depositor or the Trust Depositor shall
withdraw, liquidate or be removed from the Trust, this Agreement shall be
terminated in accordance with Section 9.01 90 days after the date of such event,
unless within such 90 day period, the Owner Trustee shall have received written
instructions from the Required Holders not to dissolve or terminate the Trust.
Promptly after the occurrence of any Insolvency Event with respect to the Trust
Depositor, the Trust Depositor shall give the Indenture Trustee and Owner
Trustee written notice thereof, and the Indenture Trustee shall give prompt
written notice to the Noteholders thereof. Upon a termination pursuant to this
Section, the Owner Trustee shall direct the Indenture Trustee promptly to sell,
at the expense of the Trust, the Trust Assets in a commercially reasonable
manner and on commercially reasonable terms. The proceeds of such a sale of the
Trust Assets shall be treated as Collections under the Transfer and Servicing
Agreement.

powers; and (a) having a combined capital and surplus of at least $50,000,000
and subject to supervision or

                                      -28-

examination by federal or state authorities; and having (or having a parent that
has) a rating of at least Baa3 by Moody's, BBB- by S&P, and BBB- by Fitch (if
rated by Fitch); or (b) which the Rating Agencies have otherwise indicated in
writing is an entity acceptable to act as Owner Trustee hereunder. If such
corporation shall publish reports of condition at least annually pursuant to law
or to the requirements of the aforesaid supervising or examining authority, then
for the purpose of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time the
Owner Trustee shall cease to be eligible in accordance with the provisions of
this Section, the Owner Trustee shall resign immediately in the manner and with
the effect specified in Section 10.02.

         SECTION 10.02. RESIGNATION OR REMOVAL OF OWNER TRUSTEE. The Owner
Trustee may at any time resign and be discharged from the trusts hereby created
by giving written notice thereof to the Administrator. Upon receiving such
notice of resignation, the Administrator shall promptly appoint a successor
Owner Trustee by written instrument, in duplicate, one copy of which instrument
shall be delivered to the resigning Owner Trustee and one copy to the successor
Owner Trustee. If no successor Owner Trustee shall have been so appointed and
have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Owner Trustee may petition any court of competent
jurisdiction for the appointment of a successor Owner Trustee. Any successor
Owner Trustee appointed hereunder shall promptly file an amendment to the
Certificate of Trust to the extent required by Delaware law.

         If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 10.01 and shall fail to resign after
written request therefor by the Administrator, or if at any time the Owner
Trustee shall be legally unable to act, or shall be adjudged bankrupt or
insolvent, or a receiver of the Owner Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Owner
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then the Administrator, may remove the Owner
Trustee. If the Administrator shall remove the Owner Trustee under the authority
of the immediately preceding sentence, the Administrator shall promptly appoint
a successor Owner Trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the outgoing Owner Trustee so removed and one
copy to the successor Owner Trustee, and shall pay all fees owed to the outgoing
Owner Trustee.

         Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 10.03 and payment of all fees and expenses owed to
the outgoing Owner Trustee.

                                      -29-

Owner Trustee to each Rating Agency.

         SECTION 10.03. SUCCESSOR OWNER TRUSTEE. Any successor Owner Trustee
appointed pursuant to Section 10.02 shall execute, acknowledge and deliver to
the Administrator, and to its predecessor Owner Trustee an instrument accepting
such appointment under this Agreement, and thereupon the resignation or removal
of the predecessor Owner Trustee shall become effective, and such successor
Owner Trustee, without any further act, deed or conveyance, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
under this Agreement, with like effect as if originally named as Owner Trustee.
The predecessor Owner Trustee shall upon payment of its fees and expenses
deliver to the successor Owner Trustee all documents and statements and monies
held by it under this Agreement; and the Administrator and the predecessor Owner
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 Owner Trustee all such rights, powers, duties and obligations.

         No successor Owner Trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor Owner Trustee shall
be eligible pursuant to Section 10.01.

         Upon acceptance of appointment by a successor Owner Trustee pursuant to
this Section, the Administrator shall mail notice thereof to the
Certificateholder, the Indenture Trustee, the Noteholders and each Rating
Agency. If the Administrator shall fail to mail such notice within ten days
after acceptance of such appointment by the successor Owner Trustee, the
successor Owner Trustee shall cause such notice to be mailed at the expense of
the Administrator.

         SECTION 10.04. MERGER OR CONSOLIDATION OF OWNER TRUSTEE. Any
corporation into which the Owner 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 Owner Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Owner Trustee, shall be the successor of the Owner Trustee
hereunder, without the execution or filing of any instrument or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, that such corporation shall be eligible pursuant to
Section 10.01 and, provided, further, that the Owner Trustee shall mail notice
of such merger or consolidation to each Rating Agency.

         SECTION 10.05. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Estate or any

                                      -30-
<PAGE>   36

financed Equipment may at the time be located, the Administrator and the Owner
Trustee acting jointly shall have the power and shall execute and deliver all
instruments to appoint one or more Persons approved by the Administrator and
Owner Trustee to act as co-trustee, jointly with the Owner Trustee, or as
separate trustee or separate trustees, of all or any part of the Trust Estate,
and to vest in such Person, in such capacity, such title to the Trust or any
part thereof and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as the Administrator and the Owner
Trustee may consider necessary or desirable. If the Administrator shall not have
joined in such appointment within 15 days after the receipt by it of a request
so to do, the Owner Trustee alone shall have the power to make such appointment.
No co-trustee or separate trustee under this Agreement shall be required to meet
the terms of eligibility as a successor Owner Trustee pursuant to Section 10.01
and no notice of the appointment of any co-trustee or separate trustee shall be
required pursuant to Section 10.03.

         Each separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:

         (a)      all rights, powers, duties and obligations conferred or
                  imposed upon the Owner Trustee shall be conferred upon and
                  exercised or performed by the Owner Trustee and such separate
                  trustee or co-trustee jointly (it being understood that such
                  separate trustee or co-trustee is not authorized to act
                  separately without the Owner 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, the
                  Owner 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
                  Estate or any portion thereof in any such jurisdiction) shall
                  be exercised and performed singly by such separate trustee or
                  co-trustee, but solely at the direction of the Owner Trustee;

         (b)      no trustee under this Agreement shall be personally liable by
                  reason of any act or omission of any other trustee under this
                  Agreement; and

         (c)      the Administrator and the Owner Trustee acting jointly may at
                  any time accept the resignation of or remove any separate
                  trustee or co-trustee.

         Any notice, request or other writing given to the Owner Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article. Each separate trustee and co-trustee, upon its
acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Owner
Trustee

                                      -31-
<PAGE>   37

or separately, as may be provided therein, subject to all the provisions of this
Agreement, specifically including every provision of this Agreement relating to
the conduct of, affecting the liability of or affording protection to, the Owner
Trustee. Each such instrument shall be filed with the Owner Trustee and a copy
thereof given to the Administrator.

         Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as 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

Trustee, without the consent of any of the Noteholders or the Certificateholder,
to cure any ambiguity, to correct or supplement any provisions in this Agreement
or to add any other provisions with respect to matters or questions arising

Opinion of Counsel, adversely affect in any material respect the interests of
any Noteholder or the Certificateholder.

         (b) This Agreement may also be amended from time to time by the Trust
Depositor, and the Owner Trustee, with the consent of the Required Holders, for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement, or of modifying in any manner the
rights of the Noteholders or the Certificateholder; provided, however, that no
such amendment shall increase or reduce in any manner the amount of, or
accelerate or delay the timing of, (i) collections of payments on Contracts or
distributions that shall be required to be made for the benefit of the
Noteholders or the Certificateholder, or (ii) eliminate the Certificateholder

         (c) Prior to the execution of any such amendment or consent, the Trust
Depositor shall furnish written notification of the substance of such amendment
or consent, together with a copy thereof, to the Indenture Trustee, the
Administrator and each Rating Agency.

         (d) Promptly after the execution of any such amendment or consent, the
Owner Trustee shall furnish written notification of the substance of such
amendment or consent to each Certificateholder. It shall not be necessary for
the consent of the Certificateholder, Noteholders or the Indenture Trustee
pursuant to this Section to approve the particular form of any proposed
amendment or consent, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents (and any other
consents of the Certificateholder provided for in this Agreement or in any other
Transaction Document) and of evidencing the authorization of the execution
thereof by the Certificateholder shall be subject to such reasonable
requirements as the Owner Trustee may prescribe.

         (e) Promptly after the execution of any amendment to the Certificate of
Trust, the Owner Trustee shall cause the filing of such amendment with the
Secretary of State.

         (f) Prior to the execution of any amendment to this Agreement or the
Certificate of Trust, the Owner Trustee shall be entitled to receive and rely
upon an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement. The Owner Trustee may, but shall not
be obligated to, enter into any such amendment that affects the Owner Trustee's
own rights, duties or immunities under this Agreement or otherwise.

         SECTION 11.02. NO LEGAL TITLE TO TRUST ESTATE IN OWNER. The Owner shall
not have legal title to any part of the Trust Estate. The Owner shall be
entitled to receive distributions with respect to its undivided ownership
interest herein only in accordance with Articles Five and Nine. No transfer, by
operation of law or otherwise, of any right, title or interest of the Owner to
and in its ownership interest in the Trust Estate shall operate to terminate
this Agreement or the trusts hereunder or entitle any transferee to an
accounting or to the transfer to it of legal title to any part of the Trust
Estate.

         SECTION 11.03. LIMITATIONS ON RIGHTS OF OTHERS. Except for Section
2.07, the provisions of this Agreement are solely for the benefit of the Owner
Trustee, the Trust Depositor, the Owner, the Administrator and, to the extent
expressly provided herein, the Indenture Trustee and the Noteholders, and
nothing in this Agreement (other than Section 2.07), whether express or implied,
shall be construed to give to any other Person any legal or equitable right,
remedy or claim in the Trust Estate or under or in respect of this Agreement or
any covenants, conditions or provisions contained herein.

Owner Trustee, Indenture Trustee and the Certificateholder that, for purposes of
federal income, state and local income and single business tax and any other
income taxes, the Trust will be disregarded as a separate entity for federal

credit of the Trust will be treated as such items of the Certificateholder. The

Depositor and any other Certificateholder, by acceptance of a Trust Certificate,
agrees to treat, and to take no action inconsistent with such treatment of, the
Trust for federal, state and local income tax purposes.

         Each Certificateholder, by its acceptance of a Trust Certificate or
beneficial interest in a Trust Certificate, covenants and agrees that such
Certificateholder will not at any time institute against the Trust or the Trust
Depositor, or join in any institution against the Trust or the Trust Depositor
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings, or other proceedings under any United States federal or state
bankruptcy or similar law in connection with any obligations relating to the
Trust Certificate, the Notes, the Trust Agreement or any of the other
Transaction Documents.

         Distributions on this Trust Certificate will be made as provided in the
Trust Agreement by the Owner Trustee or its Agent by wire transfer or check
mailed to the Certificateholder of record in the Certificate Register without
the presentation or surrender of this Trust Certificate or the making of any
notation hereon. Except as otherwise provided in the Trust Agreement and
notwithstanding the above, the final distribution on this Trust Certificate will
be made after due notice by the Owner Trustee of the pendency of such
distribution and only upon presentation and surrender of this Trust Certificate
at the office or agency maintained for that purpose by the Owner Trustee's
affiliate, The Bank of New York, in the City of New York, State of New York.

         Reference is hereby made to the further provisions of this Trust
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon shall have been
executed by an authorized officer of the Owner Trustee, by manual signature,
this Trust Certificate shall not entitle the Holder hereof to any benefit under
the Trust Agreement or any other Transaction Document or be valid for any
purpose.

         THIS TRUST CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS,
AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                            {REVERSE OF CERTIFICATE}

         The Trust Certificate does not represent an obligation of, or an
interest in the Trust Depositor, ORIX Credit Alliance, as the Originator or
Servicer, the Owner Trustee, the Indenture Trustee or any of their respective
Affiliates and no recourse may be had against such parties or their assets,
except as expressly set forth or contemplated herein or in the Trust Agreement
or the other Transaction Documents. In addition, this Trust Certificate is not
guaranteed by any governmental agency or instrumentality and is limited in right
of payment to certain collections and recoveries with respect to the Contracts
and certain other amounts, in each case as more specifically set forth herein
and in the Transfer and Servicing Agreement. A copy of each of the Transfer and
Servicing Agreement and the Trust Agreement may be examined by any
Certificateholder upon written request during normal business hours at the
principal office of the Trust Depositor and at such other places, if any,
designated by the Trust Depositor.

         The Trust Agreement permits, with certain exceptions therein provided,
the amendment thereof and the modification of the rights and obligations of the
Trust Depositor and the rights of the Certificateholder under the Trust
Agreement at any time by the Trust Depositor and the Owner Trustee with the
consent of the Required Holders (as defined in the Transfer and Servicing
Agreement). Any such consent shall be conclusive and binding on the Holder and
on all future Holders of this Trust Certificate and of any Trust Certificate
issued upon the transfer hereof or in exchange hereof or in lieu hereof, whether
or not notation of such consent is made upon this Trust Certificate. The Trust
Agreement also permits the amendment thereof, in certain limited circumstances,
without the consent of the Holder of the Trust Certificate or any Noteholder.

         As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of this Trust Certificate is registerable in the
Certificate Register upon surrender of this Trust Certificate for registration
of transfer at the offices or agencies of the Certificate Registrar maintained
by The Bank of New York, an affiliate of the Owner Trustee in New York, New
York, accompanied by a written instrument of transfer in form satisfactory to
the Owner Trustee and the Certificate Registrar in Newark, Delaware executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon a new Trust Certificate evidencing the same aggregate interest in the
Trust will

                                      -4-

be issued to the designated transferee. The initial Certificate Registrar
appointed under the Trust Agreement is the Owner Trustee.

         Except as provided in the Trust Agreement, the Trust Certificate is
issuable only as a registered Trust Certificate without coupons. No service
charge will be made for any registration of transfer of such Trust Certificate,
but the Owner Trustee or the Certificate Registrar may require payment of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

         The Owner Trustee, the Certificate Registrar and any of their
respective agents may treat the Person in whose name this Trust Certificate is
registered as the owner hereof for all purposes, and none of the Owner Trustee,
the Certificate Registrar or any such agent shall be affected by any notice to
the contrary.

         The obligations and responsibilities created by the Trust Agreement and
the Trust created thereby shall terminate upon the payment to Certificateholder
of all amounts required to be paid to such Holder pursuant to the Trust
Agreement and the Transfer and Servicing Agreement and the deposition of all
property held as part of the Trust Estate. The Trust Depositor may at its option
purchase the Trust Estate at the times and at the prices specified in the
Transfer and Servicing Agreement.

         The Trust Certificate may not be acquired by a Benefit Plan. By
accepting and holding this Trust Certificate, the Holder hereof shall be deemed
to have represented and warranted that it is not a Benefit Plan and is not
acquiring this Trust Certificate or an interest therein for the account of such
an entity.
