                                PLEDGE AGREEMENT

     This PLEDGE AGREEMENT (this "AGREEMENT") is made as of January 20, 1999
(the "EFFECTIVE DATE"), by NETWORK APPLIANCE, INC., a California corporation
("NAI"); BNP LEASING CORPORATION, a Delaware corporation ("BNPLC"); BANQUE
NATIONALE DE PARIS ("BNPLC'S PARENT"), as a "PARTICIPANT"; and BANQUE NATIONALE
DE PARIS, acting in its capacity as agent for BNPLC and the Participants (in
such capacity, "AGENT"), is made and dated as of the Effective Date.

                                    RECITALS

     A.   NAI and BNPLC are parties to: (i) a Common Definitions and Provisions
Agreement dated as of the Effective Date (the "COMMON DEFINITIONS AND PROVISIONS
Agreement"); and (ii) a Purchase Agreement dated as of the Effective Date (the
"PURCHASE AGREEMENT"), pursuant to which NAI has agreed to make a "SUPPLEMENTAL
PAYMENT" or "ISSUE 97-10 PREPAYMENT" (both as defined in the Common Definitions
and Provisions Agreement), in consideration of the rights granted to NAI by the
Purchase Agreement.

     B.   Pursuant to a Participation Agreement dated the date hereof (the
"PARTICIPATION AGREEMENT"), BNPLC's Parent has agreed with BNPLC to participate
in the risks and rewards to BNPLC of the Purchase Agreement and other Operative
Documents (as defined in the Common Definitions and Provisions Agreement), and
the parties to this Agreement anticipate that other financial institutions may
become parties to the Participation Agreement as Participants, agreeing to
participate in the risks and rewards to BNPLC of the Purchase Agreement and
other Operative Documents.

     C.   NAI may from time to time deliver cash collateral for its obligations
to NPLC under the Purchase Agreement and for BNPLC's corresponding obligations
to Participants under the Participation Agreement. This Agreement sets forth the
terms and conditions governing such cash collateral.

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

                    ARTICLE I DEFINITIONS AND INTERPRETATION

     Section 1.1 Capitalized Terms Used But Not Defined in This Agreement. All
capitalized terms used in this Agreement which are defined in Article I of the
Common Definitions and Provisions Agreement and not otherwise defined herein
shall have the same meanings herein as set forth in the Common Definitions and
Provisions Agreement. All terms used in this Agreement which are defined in the
UCC and not otherwise defined herein shall have the same meanings herein as set
forth therein, except where the context otherwise requires.

     Section 1.2 Definitions. When used in this Agreement, the following terms
shall have the following respective meanings:

          "ACCOUNT" shall mean any deposit account maintained by a Deposit Taker
     into which Cash Collateral may be deposited at any time, excluding the
     Transition Account.

          "ACCOUNT OFFICE" shall mean, with respect to any Account maintained by
     any Deposit Taker, the office of such Deposit Taker in California or New
     York at which such Account is maintained as specified in the applicable
     Deposit Taker's Acknowledgment and Agreement.

   6

          "AGENT" shall have the meaning given to that term in the introductory
     paragraph hereof.

          "BNPLC" shall have the meaning given to that term in the introductory
     paragraph hereof.

          "BNPLC'S CORRESPONDING OBLIGATIONS TO PARTICIPANTS" shall mean BNPLC's
     obligations under the Participation Agreement to pay Participants their
     respective Percentages of (or amounts equal to their respective Percentages
     of) sums "actually received by BNPLC" (as defined in the Participation
     Agreement) in satisfaction of NAI's Purchase Agreement Obligations;
     provided, however, any modification of the Participation Agreement executed
     after the date hereof without NAI's written consent shall not be considered
     for purposes of determining BNPLC's Corresponding Obligations to
     Participants under this Agreement.

          "CASH COLLATERAL" shall mean (i) all money of NAI which NAI has
     delivered to Agent for deposit with a Deposit Taker pursuant to this
     Agreement, and (ii) any additional money delivered to Agent as Collateral
     pursuant to Section 4.9.

          "CERTIFICATE OF DEPOSIT" shall mean a certificate of deposit issued by
     a Deposit Taker as required by Section 5.4 below to evidence an Account
     into which Cash Collateral has been deposited pursuant to this Agreement.
     Each Certificate of Deposit shall be issued in an amount equal to the Value
     of the Account which it evidences and shall otherwise be in the form set
     forth as ATTACHMENT 1.

          "COLLATERAL" shall have the meaning given to that term in Section 2.1
     hereof.

          "COLLATERAL IMBALANCE" shall mean on any date prior to the Designated
     Sale Date that the Value (without duplication) of Accounts maintained by
     and Certificates of Deposit issued by the Deposit Taker for any Participant
     (other than a Disqualified Deposit Taker) does not equal such Participant's
     Percentage, multiplied by the lesser of (1) the Minimum Collateral Value in
     effect on such date, or (2) the aggregate Value of all Collateral subject
     to this Agreement on such date. For purposes of determining whether a
     Collateral Imbalance exists, the Value of any Accounts maintained by a bank
     that is acting as Deposit Taker for two or more Participants will be deemed
     to be held for them in proportion to their respective Percentages, and the
     Value of any Accounts maintained by a bank as Deposit Taker for both a
     Participant and BNPLC (as in the case of BNPLC's Parent acting as Deposit
     Taker for itself, as a Participant, and for BNPLC) will be deemed to be
     held for the Participant only to the extent necessary to prevent or
     mitigate a Collateral Imbalance and otherwise for BNPLC.

          "COLLATERAL PERCENTAGE" shall mean the percentage designated by NAI or
     required during a Mandatory Collateral Period pursuant to Article III.

          "DEFAULT" means any Event of Default and any default, event or
     condition which would, with the giving of any requisite notices and the
     passage of any requisite periods of time, constitute an Event of Default.

          "DEPOSIT TAKER" for BNPLC shall mean BNPLC's Parent and for each
     Participant shall mean the Participant itself; provided, that each of BNPLC
     and the Participants, for itself only, may from time to time designate
     another Deposit Taker as provided in Sections 4.4 and 4.5 below.

          "DEPOSIT TAKER LOSSES" shall mean the Value of any Cash Collateral
     delivered to a Deposit Taker, but that the Deposit Taker will not (because
     of the insolvency of the Deposit Taker, offsets by the Deposit Taker in
     violation of the Deposit Taker's Acknowledgment and Agreement, 



                                      -2-
   7

     or otherwise) return to NAI or return to Agent for disposition or
     application as provided herein or as required by applicable law.

          "DEPOSIT TAKER'S ACKNOWLEDGMENT AND AGREEMENT" shall have the meaning
     given to that term in subsection 4.1.2 hereof.

          "DISQUALIFIED DEPOSIT TAKER" shall mean any Deposit Taker with whom
     Agent may decline to deposit Collateral pursuant to Section 4.1.

          "EVENT OF DEFAULT" shall mean the occurrence of any of the following:

               (a)  the failure by NAI to pay all or any part of NAI's Purchase
          Agreement Obligations when due, after giving effect to any applicable
          notice and grace periods expressly provided for in the Purchase
          Agreement;

               (b)  the failure by NAI to provide funds as and when required by
          Section 5.1 of this Agreement, if within seven Business Days after
          such failure commences NAI does not (1) cure such failure by
          delivering the funds required by Section 5.1, and (2) pay to BNPLC as
          additional Rent under the Lease an amount equal to interest at the
          Default Rate (as defined in the Lease) on such funds for the period
          from which they were first due to the date of receipt by Agent;

               (c)  the failure of the pledge or security interest contemplated
          herein in the Transition Account or any Account, Certificate of
          Deposit or Cash Collateral to be a Qualified Pledge (regardless of the
          characterization of the Transition Account or any Accounts,
          Certificates of Deposit or Cash Collateral as deposit accounts,
          instruments or general intangibles under the UCC), if within five
          Business Days after NAI becomes aware of such failure, NAI does not
          (1) notify Agent, BNPLC and the Participants of such failure, and (2)
          cure such failure, and (3) to the extent required by Section 7.2.9,
          pay to BNPLC any additional Base Rent that has accrued under the Lease
          because of (or that would have accrued if BNPLC had been aware of)
          such failure, together with interest at the Default Rate on any such
          additional Base Rent;

               (d)  the failure of any representation herein by NAI to be true
          (other than a failure described in another clause of this definition
          of Event of Default), if such failure is not cured within thirty days
          after NAI receives written notice thereof from Agent;

               (e)  the failure of any representation made by NAI in subsection
          7.1.1 to be true, if within fifteen (15) days after NAI becomes aware
          of such failure, NAI does not (1) notify Agent, BNPLC and the
          Participants of such failure, and (2) cure such failure, and (3) pay
          to BNPLC any additional Base Rent that has accrued under the Lease
          because of (or that would have accrued if BNPLC had been aware of)
          such failure, and (4) pay to BNPLC interest at the Default Rate on any
          such additional Base Rent;

               (f)  the failure by NAI timely and properly to observe, keep or
          perform any covenant, agreement, warranty or condition herein required
          to be observed, kept or performed (other than a failure described in
          another clause of this definition of Event of Default), if such
          failure is not cured within thirty days after NAI receives written
          notice thereof from Agent; and



                                      -3-
   8

               (g)  the failure by BNPLC to pay when due on or after the
          Designated Sale Date any of BNPLC's Corresponding Obligations to
          Participants, after giving effect to any applicable notice and grace
          periods expressly provided for in the Participation Agreement.

     Notwithstanding the foregoing, if ever the aggregate Value of Cash
     Collateral held by Agent and the Deposit Takers EXCEEDS the Minimum
     Collateral Value then in effect, a failure of the pledge or security
     interest contemplated herein in SUCH EXCESS Cash Collateral to be a valid,
     perfected, first priority pledge or security interest shall not constitute
     an Event of Default under this Agreement. Accordingly, to provide a cure as
     required to avoid an Event of Default under clauses (c) or (e) of this
     definition, NAI could deliver additional Cash Collateral - the pledge of
     which or security interest in which created by this Agreement is a
     Qualified Pledge sufficient in amount to cause the aggregate Value of the
     Cash Collateral then held by Agent and the Deposit Takers subject to a
     Qualified Pledge hereunder to equal or exceed the Minimum Collateral Value.

          "FAILED COLLATERAL TEST DATE" means any date upon which commences a
     Mandatory Collateral Period as described in Part III of Schedule 1.

          "INITIALLY QUALIFIED DEPOSIT TAKER" means (1) Banque Nationale de
     Paris, acting through any branch, office or agency that can lawfully
     maintain an Account as a Deposit Taker hereunder, and (2) any of the fifty
     largest (measured by total assets) U.S. banks, or one of the one hundred
     largest (measured by total assets) banks in the world, with debt ratings of
     at least (i) A- (in the case of long term debt) and A-1 (in the case of
     short term debt) or the equivalent thereof by Standard and Poor's
     Corporation, and (ii) A3 (in the case of long term debt) and P-2 (in the
     case of short term debt) or the equivalent thereof by Moody's Investor
     Service, Inc. The parties believe it improbable that the ratings systems
     used by Standard and Poor's Corporation and by Moody's Investor Service,
     Inc. will be discontinued or changed, but if such ratings systems are
     discontinued or changed, NAI shall be entitled to select and use a
     comparable ratings systems as a substitute for the S&P Rating or the Moody
     Rating, as the case may be, for purposes of determining the status of any
     bank as an Initially Qualified Deposit Taker.

          "LIEN" shall mean, with respect to any property or assets, any right
     or interest therein of a creditor to secure indebtedness of any kind which
     is owed to him or any other arrangement with such creditor which provides
     for the payment of such indebtedness out of such property or assets or
     which allows him to have such indebtedness satisfied out of such property
     or assets prior to the general creditors of any owner thereof, including
     any lien, mortgage, security interest, pledge, deposit, production payment,
     rights of a vendor under any title retention or conditional sale agreement
     or lease substantially equivalent thereto, tax lien, mechanic's or
     materialman's lien, or any other charge or encumbrance for security
     purposes, whether arising by law or agreement or otherwise, but excluding

          with the giving of any requisite notices and the passage of any
          requisite periods of time, constitute an "Event of Default" under and
          as defined in the Lease, if such other default, event or failure
          involves a material noncompliance with Applicable Law. (For purposes
          of this definition, "material" noncompliance with Applicable Law will

     and as defined in the Participation Agreement for purposes of computing
     such Participant's right thereunder to receive payments of (or amounts
     equal to a percentage of) any sales proceeds or Supplemental Payment
     received by BNPLC under the Purchase Agreement. Percentages may be adjusted
     from time to time as provided in the Participation Agreement or as provided
     in supplements thereto executed as provided in the Participation Agreement.

     Section 1.5 References and Titles. All references in this Agreement to
Attachments, Articles, Sections, subsections, and other subdivisions refer to

                          ARTICLE II SECURITY INTEREST

     Section 2.1 Pledge and Grant of Security Interest. As security for the
Secured Obligations, NAI hereby pledges and assigns to Agent (for the ratable
benefit of BNPLC and the Participants) and grants to Agent (for the ratable
benefit of BNPLC and the Participants) a continuing security interest and lien
in and against all right, title and interest of NAI in and to the following
property, whether now owned or hereafter acquired by NAI (collectively and
severally, the "COLLATERAL"):

          (a)  All Cash Collateral, all Accounts, the Transition Account and all
     Certificates of Deposit issued from time to time and general intangibles
     arising therefrom or relating thereto (however, "general intangibles" as
     used in this clause shall not include any general intangibles not related
     to Cash Collateral, Accounts, the Transition Account or Certificates of
     Deposit issued from time to time, and thus will not include, without
     limitation, any intellectual property of NAI); and all documents,
     instruments and agreements evidencing the same; and all extensions,
     renewals, modifications and replacements of the foregoing; and any interest
     or other amounts payable in connection therewith; and

          (b)  All proceeds of the foregoing (including whatever is receivable
     or received when Collateral or proceeds is invested, sold, collected,
     exchanged, returned, substituted or otherwise disposed of, whether such
     disposition is voluntary or involuntary, including rights to payment and
     return premiums and insurance proceeds under insurance with respect to any
     Collateral, and all rights to payment with respect to any cause of action
     affecting or relating to the Collateral).

The pledge, assignment and grant of a security interest made by NAI hereunder is
for security of the Secured Obligations only; the parties to this Agreement do
not intend that NAI's delivery of the Collateral to Agent as herein provided
will constitute an advance payment of any Secured Obligations or liquidated
damages, nor do the parties intend that the Collateral increase the dollar
amount of the Secured Obligations.

     Section 2.2 Return of Collateral After the Secured Obligations are
Satisfied in Full. If any proceeds of Collateral remain after all Secured
Obligations have been paid in full, Agent will deliver or direct the Deposit
Takers to deliver such proceeds to NAI or other Persons entitled thereto by law.

            ARTICLE III DESIGNATION OF MINIMUM COLLATERAL PERCENTAGE

     Section 3.1 Determination of Minimum Collateral Percentage Generally.
Effective as of the date of this Agreement, and until a new Collateral
Percentage becomes effective, the Collateral Percentage is zero percent (0%).
Subject to the provisions of this Article III, NAI may from time to time
designate a new Collateral Percentage between 0% and 100% by written notice
delivered to Agent, BNPLC and the Participants in the form of ATTACHMENT 3. Any
new Collateral Percentage so designated shall not become effective, however,
until the commencement of the later of (A) the first Base Rent Period to
commence after the second anniversary of the Effective Date, or (B) the next
following Base Rent Period which is at least ten Business Days after (1) the
receipt of such notice by Agent, BNPLC and the Participants, and (2) the
approval in writing by a "Majority" under (and as defined in) the Participation
Agreement of the new Collateral Percentage designated by NAI (which approval may
be withheld in the sole and absolute discretion of BNPLC or any Participant);
provided, however, the prior approval of a Majority under the Participation
Agreement will not be required for a designation by NAI of a Collateral
Percentage above zero percent (0%) that is to become effective as of the
commencement the first Base 



                                      -7-
   12

Rent Period starting after the second anniversary of the Effective Date, if the
notice from NAI designating such Collateral Percentage is delivered to Agent,
BNPLC and the Participants at least ten Business Days prior to such Base Rent
Period. In any event, if NAI provides more than one notice of a change in the
Collateral Percentage to be effective on a particular Base Rent Date, then the
latest such notice from NAI which satisfies the requirements of the preceding
sentence (and of Sections 3.2 and 3.3) will control. After any Collateral
Percentage becomes effective as provided in this Article, it shall remain in
effect until a different Collateral Percentage becomes effective as provided in
this Article.

     Section 3.2 Limitations on NAI's Right to Lower the Collateral Percentage.
Notwithstanding the foregoing, no designation by NAI of a new Collateral
Percentage will be effective to reduce the Collateral Percentage if the
designation is given, or the reduction would otherwise become effective, on or
after the Designated Sale Date or when any of the following shall have occurred
and be continuing:

          3.2.1 any Material Lease Default;

          3.2.2 any Event of Default under and as defined in this Agreement;

          3.2.3 any Default under and as defined in this Agreement -- excluding,
     however, any such Default limited to a failure of NAI described in clause
     (c) or clause (e) of the definition of Event of Default above, with respect
     to which the time for cure specified in clause (c) or clause (e), as
     applicable, has not expired.

        Section 3.3 Mandatory Collateral Periods. NOTWITHSTANDING ANYTHING TO
THE CONTRARY HEREIN CONTAINED, THE COLLATERAL PERCENTAGE DURING ANY MANDATORY
COLLATERAL PERIOD SHALL BE ONE HUNDRED PERCENT (100%). No later than five
Business Days prior to any Failed Collateral Test Date, NAI shall notify Agent,
BNPLC and the Participants of the conditions set forth in Part III of Schedule 1
that NAI will be unable to satisfy on the Failed Collateral Test Date.

                 ARTICLE IV PROVISIONS CONCERNING DEPOSIT TAKERS

     Section 4.1 Qualification of Deposit Takers Generally. Agent may decline to
deposit or maintain Collateral hereunder with any Person designated as a Deposit
Taker, if such Person has failed to satisfy or no longer satisfies the following
requirements:

          4.1.1 Such Person must have received from Agent and NAI a completed,
     executed Notice of Security Interest in the form of ATTACHMENT 4 (a "NOTICE
     OF SECURITY INTEREST") which specifically identifies any and all Accounts
     in which such Person shall hold Cash Collateral delivered to it pursuant to
     this Agreement and which designates Account Offices with respect to all
     such Accounts in New York or California.

          4.1.2 Such Person must have executed the Acknowledgment and Agreement
     at the end of such Notice of Security Interest (the "DEPOSIT TAKER'S
     ACKNOWLEDGMENT AND AGREEMENT") and returned the same to Agent. Further,
     such Person must have complied with the Deposit Taker's Acknowledgment and
     Agreement, and the representations set forth therein with respect to such
     Person must continue to be true and correct.

          4.1.3 Such Person must be a commercial bank, organized under the laws
     of the United States of America or a state thereof or under the laws of
     another country which is doing business in the United States of America;
     must be authorized to maintain deposit accounts for others through Account
     Offices in New York or California (as specified in the Deposit Taker's



                                      -8-
   13

     Acknowledgment and Agreement); and must be an Affiliate of BNPLC or the
     Participant for whom such Person will act as Deposit Taker or must have a
     combined capital, surplus and undivided profits of at least $500,000,000.

          4.1.4 Such Person must have complied with the provisions in this
     Agreement applicable to Deposit Takers, including the provisions of Section
     5.4 concerning the issuance and redemption of Certificates of Deposit.

     Section 4.2 Existing Deposit Takers. BNPLC's Parent (as Deposit Taker for
itself and for BNPLC) has received a Notice of Security Agreement dated the
Effective Date and has responded to such a notice with a Deposit Taker's
Acknowledgment and Agreement dated the Effective Date, as contemplated in
subsections 4.1.1 and 4.1.2.

     Section 4.3 Replacement of Participants Proposed by NAI. So long as no
Event of Default has occurred and is continuing, BNPLC shall not unreasonably
withhold its approval for a substitution under the Participation Agreement of a
new Participant proposed by NAI for any Participant, the Deposit Taker for whom
would no longer meet the requirements for an Initially Qualified Deposit Taker;
provided, however, that (A) the proposed substitution can be accomplished
without a release or breach by BNPLC of its rights and obligations under the
Participation Agreement; (B) the new Participant will agree (by executing a
Supplement and a supplement to the Participation Agreement as contemplated
therein and by other agreements as may be reasonably required by BNPLC and NAI)
to become a party to the Participation Agreement and to this Agreement, to
designate an Initially Qualified Deposit Taker as the Deposit Taker for it under
this Agreement and to accept a Percentage under the Participation Agreement
equal to the Percentage of the Participant to be replaced; (C) the new
Participant (or NAI) will provide the funds required to pay the termination fee
by Section 6.4 of the Participation Agreement to accomplish the substitution;
(D) NAI (or the new Participant) agrees in writing to indemnify and defend BNPLC
for any and all Losses incurred by BNPLC in connection with or because of the
substitution, including the cost of preparing supplements to the Participation
Agreement and this Agreement and including any cost of defending and paying any
claim asserted by the Participant to be replaced because of the substitution
(but not including any liability of BNPLC to such Participant for damages caused
by BNPLC's bad faith or gross negligence in the performance of BNPLC's
obligations under the Participation Agreement prior to the substitution); (E)
the new Participant shall be a reputable financial institution having a net
worth of no less than seven and one half percent (7.5%) of total assets and
total assets of no less than $10,000,000,000.00 (all according to then recent
audited financial statements); and (F) in no event will BNPLC be required to
approve a substitution pursuant to this Section 4.3 which will replace a
Participant that is an Affiliate of BNPLC. BNPLC shall attempt in good faith to
assist (and cause BNPLC's Parent to attempt in good faith to assist) NAI in
identifying a new Participant that NAI may propose to substitute for an existing
Participant pursuant to this Section, as NAI may reasonably request from time to
time. However, in no event shall BNPLC itself, or any of its Affiliates, be
required to take the Percentage of any Participant to be replaced.

     Section 4.4 Mandatory Substitution for Disqualified Deposit Takers. If any
Deposit Taker shall cease to satisfy the requirements set forth in Section 4.1,
the party for whom such Disqualified Deposit Taker has been designated as
Deposit Taker (i.e., BNPLC or the applicable Participant) shall promptly (1)
provide notice thereof to Agent and NAI, and (2) designate a substitute Deposit
Taker and cause the substitute to satisfy the requirements set forth in Section
4.1. Pending the designation of the substitute and the satisfaction by it of the
requirements set forth in Section 4.1, Agent may withdraw Collateral held by the
Disqualified Deposit Taker and deposit such Collateral with other Deposit
Takers, subject to Section 5.3 below.



                                      -9-
   14

     Section 4.5 Voluntary Substitution of Deposit Takers. With the written
approval of Agent, which approval will not be unreasonably withheld, BNPLC or
any Participant may at any time designate for itself a new Deposit Taker (in
replacement of any prior Deposit Taker acting for it hereunder); provided, the
Person so designated has satisfied the requirements set forth in Section 4.1;
and, provided further, unless the designation of a new Deposit Taker is required
by Section 4.4 to replace a Disqualified Deposit Taker, at the time of the
replacement such Person must be an Initially Qualified Deposit Taker.

     Section 4.6 Delivery of Notice of Security Interest by NAI and Agent. To
the extent required for the designation of a new Deposit Taker by BNPLC or any
Participant pursuant to Section 4.5, or to permit the substitution or
replacement of a Deposit Taker for BNPLC or any Participant as provided in
Sections 4.4 and 4.5, NAI and Agent shall promptly execute and deliver any
properly completed Notice of Security Interest requested by BNPLC or the
applicable Participant.

     Section 4.7 Constructive Possession of Collateral. The possession by a
Deposit Taker of any deposit accounts, money, instruments, chattel paper or
other property constituting Collateral or evidencing Collateral shall be deemed
to be possession by Agent or a person designated by Agent, for purposes of
perfecting the security interest granted to Agent hereunder pursuant to the UCC
or other Applicable Law; and notifications to a Deposit Taker by other Persons
holding any such property, and Acknowledgments, receipts or confirmations from
any such Persons delivered to a Deposit Taker, shall be deemed notifications to,
or Acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of such Deposit Taker for the benefit of Agent
for the purposes of perfecting such security interests under Applicable Law.

     Section 4.8 Attempted Setoff by Deposit Takers. By delivery of a Deposit
Taker's Acknowledgment and Agreement, each Deposit Taker shall be required to
agree not to setoff or attempt a setoff, WITHOUT IN EACH CASE FIRST OBTAINING
THE PRIOR WRITTEN AUTHORIZATION OF AGENT, Secured Obligations owed to it against
any Collateral held by it from time to time. Further, by delivery of a Deposit
Taker's Acknowledgment and Agreement, each Deposit Taker shall be required to
agree not to setoff or attempt a setoff, WITHOUT IN EACH CASE FIRST OBTAINING
THE PRIOR WRITTEN AUTHORIZATION OF BOTH NAI AND AGENT, obligations owed to it
other than Secured Obligations against any Collateral held by it from time to
time. Any Deposit Taker for BNPLC or a Participant shall not be permitted by
BNPLC or the applicable Participant, as the case may be, to violate such
agreements. However, NAI acknowledges and agrees (without limiting its right to
recover damages from a Deposit Taker that violates such agreements) that Agent
shall not be responsible for, or be deemed to have taken any action against NAI
because of, any Deposit Taker's violation of such agreements; and, neither BNPLC
nor any Participant shall be responsible for, or be deemed to have taken any
action against NAI because of, any violation of such agreements by a Deposit
Taker for another party.

     Section 4.9 Deposit Taker Losses. Agent shall not be responsible for any
Deposit Taker Losses. However, Deposit Taker Losses with respect to a Deposit
Taker for a particular Participant shall reduce the amount of BNPLC's
Corresponding Obligations to Participants which are payable to such Participant
as provided in Section 2.2 of the Participation Agreement. Further, when Deposit
Taker Losses with respect to a Deposit Taker for a particular Participant are
incurred in excess of the payments of Secured Obligations that such Participant
would then have been entitled to receive under the Participation Agreement but
for such Deposit Taker Losses, such Participant must immediately pay the excess
to Agent as additional Collateral hereunder, failing which NAI may recover any
damages suffered by it because of the Deposit Taker Losses from such Deposit
Taker or such Participant.

     Section 4.10 Losses Resulting from Failure of Deposit Taker to Comply with
this Agreement. Any Participant, the Deposit Taker for whom has failed to comply
with the requirements of this Agreement or any Notices of Security Interest and
any Deposit Taker's Acknowledgments and Agreements (the 



                                      -10-
   15

"RESPONSIBLE PARTICIPANT") must defend, indemnify, and hold harmless BNPLC,
Agent and the other Participants from and against any Losses resulting from such
failure. Without limiting the foregoing, if the failure of a Deposit Taker for a
Responsible Participant to comply strictly with the terms of this Agreement
(including, without limitation, the provisions of Section 5.4 concerning the
issuance and redemption of Certificates of Deposit and the requirement that any
cash deposits be held in a deposit account located in either New York or
California) causes, in whole or in part, the security interest of Agent in the
Collateral held by such Deposit Taker to be unperfected, then any and all Losses
suffered as a result of such nonperfection shall be borne solely by the
Responsible Participant and shall not be shared by BNPLC, Agent or the other
Participants.

              ARTICLE V DELIVERY AND MAINTENANCE OF CASH COLLATERAL

     Section 5.1 Delivery of Funds by NAI. On each Base Rent Date, NAI must
deliver to Agent, subject to the pledge and security interest created hereby,
funds as Cash Collateral then needed (if any) to cause the Value of the
Collateral to be no less than the Minimum Collateral Value. Each delivery of
funds required by the preceding sentence must be received by Agent no later than
12:00 noon (San Francisco time) on the date it is required; if received after
12:00 noon it will be considered for purposes of the Lease as received on the
next following Business Day. At least five Business Days prior to any Base Rent
Date upon which it is expected that NAI will be required to deliver additional
funds pursuant to this Section, NAI shall notify BNPLC, Agent and each of the
Participants thereof and of the amount NAI expects to deliver to Agent as Cash
Collateral on the applicable Base Rent Date. In addition to required deliveries
of Cash Collateral as provided in the foregoing provisions, NAI may on any date
(whether or not a Base Rent Date) deliver additional Cash Collateral to Agent as
necessary to prevent any Default from becoming an Event of Default. Upon receipt
of any funds delivered to it by NAI as Cash Collateral, Agent shall immediately
deposit the same with the Deposit Takers in accordance with the requirements of
Sections 5.3 and 5.4 below.

     Section 5.2 Transition Account. Pending deposit in the Accounts or other
application as provided herein, all Cash Collateral received by Agent shall be
credited to and held by Agent in an account (the "TRANSITION ACCOUNT") styled
"NAI Collateral Account, held for the benefit of BNP Leasing Corporation and the
Participants," separate and apart from all other property and funds of NAI or
other Persons, and no other property or funds shall be deposited in the
Transition Account. The books and records of Agent shall reflect that the
Transition Account and all Cash Collateral on deposit therein are owned by NAI,
subject to a pledge and security interest in favor of Agent for the benefit of
BNPLC and Participants.

     Section 5.3 Allocation of Cash Collateral Among Deposit Takers. Funds
received by Agent from NAI as Cash Collateral will be allocated for deposit
among the Deposit Takers as follows:

     first, to the extent possible the funds will be allocated as required to
     rectify and prevent any Collateral Imbalance; and

     second, the funds will be allocated to the Deposit Taker for BNPLC, unless
     the Deposit Taker for BNPLC has become a Disqualified Deposit Taker, in
     which case the funds will be allocated to other Deposit Takers who are not
     Disqualified Deposit Takers as Agent deems appropriate.

Further, if for any reason a Collateral Imbalance is determined by Agent to
exist, Agent shall, as required to rectify or mitigate the Collateral Imbalance,
promptly reallocate Collateral among Deposit Takers by withdrawing Cash
Collateral from some Accounts and redepositing it in other Accounts. (If any
party to this Agreement believes that the Value of the Accounts held by a
particular Deposit Taker causes a Collateral Imbalance to exist, that party will
promptly notify BNPLC, NAI and Agent.) Subject to the foregoing, and provided
that Agent does not thereby create or exacerbate a Collateral Imbalance, Agent



                                      -11-
   16

may withdraw and redeposit Cash Collateral in order to reallocate the same among
Deposit Takers from time to time as Agent deems appropriate. For purposes of
illustration only, examples of the allocations required by this Section are set
forth in ATTACHMENT 5.

     Section 5.4 Issuance and Redemption of Certificates of Deposit. Upon the
receipt of any deposit of Cash Collateral from Agent, each Deposit Taker shall
issue a Certificate of Deposit evidencing the Account into which such deposit is
made and deliver such Certificate of Deposit to Agent for the benefit of BNPLC
and the Participants. Each Certificate of Deposit shall be issued in an amount
equal to the Value of the Account which it evidences and shall otherwise be in
the form set forth as ATTACHMENT 1 to this Agreement. Upon depositing any Cash
Collateral into an Account that is already evidenced by an outstanding
Certificate of Deposit, Agent will surrender the outstanding Certificate of
Deposit, and in exchange the Deposit Taker receiving the deposit will issue a
new Certificate of Deposit, evidencing the total amount of Cash Collateral in
the Account after the deposit. A Deposit Taker that has issued a Certificate of
Deposit may require the surrender of the Certificate of Deposit as a condition
to a withdrawal from the Account evidenced thereby, including any withdrawal
required or permitted by this Agreement. Upon surrender of a Certificate of
Deposit in connection with a withdrawal of less than all of the Cash Collateral
in the Account evidenced thereby, the applicable Deposit Taker will concurrently
issue a new Certificate of Deposit to Agent, evidencing the balance of the Cash
Collateral remaining on deposit in the Account after the withdrawal.
Notwithstanding the foregoing, if any Certificate of Deposit held by Agent shall
be destroyed, lost or stolen, the Deposit Taker that issued the Certificate,
upon the written request of Agent, shall issue a new Certificate of Deposit to
Agent in lieu of and in substitution for the Certificate of Deposit so
destroyed, lost or stolen. However, as applicant for the substitute Certificate
of Deposit, Agent must indemnify (at no cost to NAI) the applicable Deposit
Taker against any liability on the Certificate of Deposit destroyed, lost or
stolen, and Agent shall furnish to the Deposit Taker an affidavit of an officer
of Agent setting forth the fact of destruction, loss or theft and confirming the
status of Agent as holder of the Certificate of Deposit immediately prior to the
destruction, loss or theft. If any Certificate of Deposit held by Agent shall
become mutilated, the Deposit Taker that issued the Certificate, upon the
written request of Agent, shall issue a new Certificate of Deposit to Agent in
exchange and substitution for the mutilated Certificate of Deposit. Agent shall
hold all Certificates of Deposit for the benefit of BNPLC and the Participants,
subject to the pledge and security interest created hereby.

     Section 5.5 Status of the Accounts Under the Reserve Requirement
Regulations. Deposit Takers shall be permitted to structure the Accounts as
nonpersonal time deposits under 12 C.F.R., Part II, Chapter 204 (commonly known
as "Regulation D"). Accordingly, each Deposit Taker may require at least seven
days advance notice of any withdrawal or transfer of funds from Accounts it
maintains and may limit the number of withdrawals or transfers from such
Accounts to no more than six in any calendar month, notwithstanding anything to
the contrary herein or in any deposit agreement that NAI and any Deposit Taker
may enter into with respect to any Account. As necessary to satisfy the seven
days notice requirement with respect to withdrawals by Agent when required by
NAI pursuant to the provisions below, Agent shall notify Deposit Takers promptly
after receipt of any notice from NAI described in subsection 6.1.2 or 6.2.1 or
in Section 6.3.

     Section 5.6 Acknowledgment by NAI that Requirements of this Agreement are
Commercially Reasonable. NAI acknowledges and agrees that the requirements set
forth herein concerning receipt, deposit, withdrawal, allocation, application
and distribution of Cash Collateral by Agent, including the requirements and
time periods set forth in the next Article, are commercially reasonable.

                    ARTICLE VI WITHDRAWAL OF CASH COLLATERAL

NAI may not withdraw Cash Collateral, except as follows:

     Section 6.1 Withdrawal of Collateral Prior to the Designated Sale Date. NAI
may require Agent to present Certificates of Deposit for payment and withdraw
Cash Collateral from Accounts on any date prior to the Designated Sale Date and
to deliver such Cash Collateral to NAI (which delivery shall be free and clear
of all liens and security interests hereunder); provided, however, that in each
case:

          6.1.1 Such withdrawal and delivery of the Cash Collateral to NAI will
     not cause the Value of the remaining Collateral to be less than the Minimum
     Collateral Value.

          6.1.2 by a notice in the form of ATTACHMENT 6, NAI must give Agent,
     BNPLC and the Participants notice of the required withdrawal at least ten
     days prior to the date upon which the withdrawal is to occur.

          6.1.3 No Default or Event of Default shall have occurred and be
     continuing at the time NAI gives the notice required by the preceding
     subsection or on the date upon which the withdrawal is required.

          6.1.4 NAI must pay to Agent any and all costs incurred by Agent in
     connection with the withdrawal.

          6.1.5 Agent shall determine the Accounts from which to make any
     withdrawal required by NAI pursuant to this Section as necessary to prevent
     or mitigate any Collateral Imbalance.

     Section 6.2 Withdrawal and Application of Cash Collateral to Reduce or
Satisfy the Secured Obligations to the Participants. To reduce the "Break Even
Price" or "Supplemental Payment" required under (and as defined in) the Purchase
Agreement (and, thus, to reduce the Secured Obligations), NAI may require Agent
to withdraw Cash Collateral then held by or for Agent pursuant to this Agreement
on the Designated Sale Date and to deliver the same on the Designated Sale Date
or on any date thereafter prior to an Event of Default (which delivery shall be
free and clear of all liens and security interests hereunder) directly to the
Participants in proportion to their respective rights to payment of BNPLC's
Corresponding Obligations to Participants and for application thereto or the
reduction thereof pursuant to Section 2.2 of the Participation Agreement;
provided, that:

          6.2.1 by a notice in the form of ATTACHMENT 7, NAI must have notified
     Agent, BNPLC and each of the Participants of the required withdrawal and
     payment to Participants at least ten days prior to the date upon which it
     is to occur;

          6.2.2 the required withdrawal shall be made as determined by Agent,
     first, from the Accounts maintained by the Deposit Takers for the
     Participants, and then (to the extent necessary) from the Accounts
     maintained by the Deposit Taker for BNPLC; and

          6.2.3 in any event, no withdrawals or payments directly to
     Participants shall be required by this Section 6.2 (or permitted over the
     objection of BNPLC) in excess of those required to satisfy BNPLC's
     Corresponding Obligations to Participants or to reduce such obligations to
     zero under the Participation Agreement.

     Section 6.3 Withdrawal and Application of Cash Collateral to Reduce or
Satisfy the Secured Obligations to BNPLC. To satisfy NAI's Purchase Agreement
Obligations, NAI may require Agent to withdraw any Cash Collateral held by the
Deposit Taker for BNPLC pursuant to this Agreement on the 



                                      -13-
   18

Designated Sale Date and to deliver the same on the Designated Sale Date or on
any date thereafter prior to an Event of Default (which delivery shall be free
and clear of all liens and security interests hereunder) directly to BNPLC as a
payment on behalf of NAI of amounts due under the Purchase Agreement; provided,
that by a notice in the form of ATTACHMENT 8, NAI must have notified Agent and
BNPLC of the required withdrawal and payment to BNPLC at least ten days prior to
the date upon which it is to occur.

          Section 6.4 Withdrawal of Cash Collateral From Accounts Maintained by
     Disqualified Deposit Takers. NAI may from time to time prior to the
     Designated Sale Date (regardless of the existence of any Default or Event
     of Default) require Agent to withdraw any or all Cash Collateral from any
     Account maintained by a Disqualified Deposit Taker and deposit it, still
     subject to the pledge and grant of security interest hereunder, with other
     Deposit Takers who are not Disqualified Deposit Takers (in accordance with
     the requirements of Sections 5.3 and 5.4) on any date prior to the
     Designated Sale Date; provided, that by a notice in the form of ATTACHMENT
     9, NAI must have notified Agent, BNPLC and each of the Participants of the
     required withdrawal at least ten days prior to the date upon which it is to
     occur.

                ARTICLE VII REPRESENTATIONS AND COVENANTS OF NAI

     Section 7.1 Representations of NAI. NAI represents to BNPLC, Agent and the
Participants as follows:

          7.1.1 NAI is the legal and beneficial owner of the Collateral (or, in
     the case of after-acquired Collateral, at the time NAI acquires rights in
     the Collateral, will be the legal and beneficial owner thereof). No other
     Person has (or, in the case of after-acquired Collateral, at the time NAI
     acquires rights therein, will have) any right, title, claim or interest (by
     way of Lien, purchase option or otherwise) in, against or to the
     Collateral, except for rights created hereunder.

          7.1.2 Agent has (or in the case of after-acquired Collateral, at the
     time NAI acquires rights therein, will have) a valid, first priority,
     perfected pledge of and security interest in the Collateral, regardless of
     the characterization of the Collateral as deposit accounts, instruments or
     general intangibles under the UCC, but assuming that the representations of
     each Deposit Taker in its Deposit Taker's Acknowledgment and Agreement are
     true.

          7.1.3 NAI has delivered to Agent, together with all necessary stock
     powers, endorsements, assignments and other necessary instruments of
     transfer, the originals of all documents, instruments and agreements
     evidencing Accounts, Certificates of Deposit or Cash Collateral.

          7.1.4 NAI's chief executive office is located at the address of NAI
     set forth in Article II of the Common Definitions and Provisions Agreement
     or at another address in California specified in a notice that NAI has
     given to Agent as required by Section 7.2.4.

          7.1.5 To the knowledge of NAI, neither the ownership or the intended
     use of the Collateral by NAI, nor the pledge of Accounts or the grant of
     the security interest by NAI to Agent herein, nor the exercise by Agent of
     its rights or remedies hereunder, will (i) violate any provision of (a)
     Applicable Law, (b) the articles or certificate of incorporation, charter
     or bylaws of NAI, or (c) any agreement, judgment, license, order or permit
     applicable to or binding upon NAI, or (ii) result in or require the
     creation of any Lien, charge or encumbrance upon any assets or properties
     of NAI except as expressly contemplated in this Agreement. Except as
     expressly contemplated in this Agreement, to the knowledge of NAI no
     consent, approval, authorization or order of, and no notice to or filing
     with any court, governmental authority or third party is required in
     connection with the pledge or grant by NAI of the security interest
     contemplated herein or the exercise by Agent of its rights and remedies
     hereunder.

     Section 7.2 Covenants of NAI. NAI hereby agrees as follows:

          7.2.1 NAI, at NAI's expense, shall promptly procure, execute and
     deliver to Agent all documents, instruments and agreements and perform all
     acts which are necessary, or which Agent may reasonably request, to
     establish, maintain, preserve, protect and perfect the Collateral, the
     pledge thereof to Agent or the security interest granted to Agent therein
     and the first priority of such pledge or security interest or to enable
     Agent to exercise and enforce its rights and remedies hereunder with
     respect to any Collateral. Without limiting the generality of the preceding
     sentence, NAI shall (A) procure, execute and deliver to Agent all stock
     powers, endorsements, assignments, financing statements and other
     instruments of transfer requested by Agent, (B) deliver to Agent promptly
     upon receipt all originals of Collateral consisting of instruments,
     documents and chattel paper and (C) cause the security interest of Agent in
     any Collateral 



                                      -15-
   20

     consisting of securities to be recorded or registered in the books of any
     financial intermediary or clearing corporation requested by Agent.

          7.2.2 NAI shall not use or consent to any use of any Collateral in
     violation of any provision of the this Agreement or any other Transaction
     Document or any Applicable Law.

          7.2.3 NAI shall pay promptly when due all taxes and other governmental
     charges, all Liens and all other charges now or hereafter imposed upon,
     relating to or affecting any Collateral.

          7.2.4 Without thirty days' prior written notice to Agent, NAI shall
     not change NAI's name or place of business (or, if NAI has more than one
     place of business, its chief executive office).

          7.2.5 NAI shall appear in and defend, on behalf of Agent, any action
     or proceeding which may affect NAI's title to or Agent's interest in the
     Collateral.

          7.2.6 Subject to the express rights of NAI under Article VI, NAI shall
     not surrender or lose possession of (other than to Agent or a Deposit Taker
     pursuant hereto), sell, encumber, lease, rent, option, or otherwise dispose
     of or transfer any Collateral or right or interest therein, and NAI shall
     keep the Collateral free of all Liens.

          7.2.7 NAI will not take any action which would in any manner impair
     the value or enforceability of Agent's pledge of or security interest in
     any Collateral, nor will NAI fail to take any action which is required to
     prevent (and which NAI knows is required to prevent) an impairment of the
     value or enforceability of Agent's pledge of or security interest in any
     Collateral.

          7.2.8 NAI shall pay (and shall indemnify and hold harmless Agent from
     and against) all Losses incurred by Agent in connection with or because of
     (A) the interest acquired by Agent in any Collateral pursuant to this
     Agreement, or (B) the negotiation or administration of this Agreement,
     whether such Losses are incurred at the time of execution of this Agreement
     or at any time in the future. Costs and expenses included in such Losses
     may include, without limitation, all filing and recording fees, taxes, UCC
     search fees and Attorneys' Fees incurred by Agent with respect to the
     Collateral.

          7.2.9 Without limiting the foregoing, within five Business Days after
     NAI becomes aware of any failure of the pledge or security interest
     contemplated herein in the Transition Account or any Account, Certificate
     of Deposit or Cash Collateral to be a valid, perfected, first priority
     pledge or security interest (regardless of the characterization of the
     Transition Account or any Accounts, Certificates of Deposit or Cash
     Collateral as deposit accounts, instruments or general intangibles under
     the UCC), NAI shall notify Agent, BNPLC and the Participants of such
     failure. In addition, if the failure would not exist but for NAI's delivery
     of Cash Collateral to Agent subject to prior Liens or other claims by one
     or more third parties, or but for the grant by NAI itself of any Lien or
     other interest in the Collateral to one or more third parties, then, in
     addition to any other remedies available to BNPLC or Agent under the
     circumstances, NAI must pay to BNPLC any additional Base Rent that has
     accrued under the Lease because of (or that would have accrued if BNPLC had
     been aware of) the failure, together with interest at the Default Rate on
     any such additional Base Rent.

                     ARTICLE VIII AUTHORIZED ACTION BY AGENT

     Section 8.1 Power of Attorney. NAI hereby irrevocably appoints Agent as
NAI's attorney-in-fact for the purpose of authorizing Agent to perform (but
Agent shall not be obligated to and shall incur no 



                                      -16-
   21

liability to NAI or any third party for failure to perform) any act which NAI is
obligated by this Agreement to perform, and to exercise, consistent with the
other provisions of this Agreement, such rights and powers as NAI might exercise
with respect to the Collateral during any period in which a Default or Event of
Default has occurred and is continuing, including the right to (a) collect by
legal proceedings or otherwise and endorse, receive and receipt for all
dividends, interest, payments, proceeds and other sums and property now or
hereafter payable on or on account of the Collateral; (b) enter into any
extension, reorganization, deposit, merger, consolidation or other agreement
pertaining to, or deposit, surrender, accept, hold or apply other property in
exchange for the Collateral; (c) insure, process, preserve and enforce the
Collateral; (d) make any compromise or settlement, and take any action it deems
advisable, with respect to the Collateral; (e) pay any indebtedness of NAI
relating to the Collateral; and (f) execute UCC financing statements and other
documents, instruments and agreements required hereunder. NAI agrees that such
care as Agent gives to the safekeeping of its own property of like kind shall
constitute reasonable care of the Collateral when in Agent's possession;
provided, however, that Agent shall not be obligated to NAI to give any notice
or take any action to preserve rights against any other Person in connection
with the Secured Obligations or with respect to the Collateral.

                         ARTICLE IX DEFAULT AND REMEDIES

     Section 9.1 Remedies. In addition to all other rights and remedies granted
to Agent, BNPLC or the Participants by this Agreement, the Lease, the Purchase
Agreement, the Participation Agreement, the UCC and other Applicable Laws, Agent
may, upon the occurrence and during the continuance of any Event of Default,
exercise any one or more of the following rights and remedies, all of which will
be in furtherance of its rights as a secured party under the UCC:

          (a)  Agent may collect, receive, appropriate or realize upon the
     Collateral or otherwise foreclose or enforce the pledge of or security
     interests in any or all Collateral in any manner permitted by Applicable
     Law or in this Agreement; and

          (b)  Agent may notify any or all Deposit Takers to pay all or any
     portion of the Collateral held by such Deposit Taker(s) directly to Agent.

Agent shall distribute the proceeds of all Collateral received by Agent after
the occurrence of an Event of Default to BNPLC and the Participants for
application to the Secured Obligations. If any proceeds of Collateral remain
after all Secured Obligations have been paid in full, Agent will deliver or
direct the Deposit Takers to deliver such proceeds to NAI or other Persons
entitled thereto. In any case where notice of any sale or disposition of any
Collateral is required, NAI hereby agrees that seven (7) Business Days notice of
such sale or disposition is reasonable.



                                      -17-
   22

                            ARTICLE X OTHER RECOURSE

     Section 10.1 Recovery Not Limited. To the fullest extent permitted by
applicable law, NAI waives any right to require that Agent, BNPLC or the
Participants proceed against any other Person, exhaust any Collateral or other
security for the Secured Obligations, or to have any Other Liable Party joined
with NAI in any suit arising out of the Secured Obligations or this Agreement,
or pursue any other remedy in their power. NAI waives any and all notice of
acceptance of this Agreement. NAI further waives notice of the creation,
modification, rearrangement, renewal or extension for any period of any of the
Secured Obligations of any Other Liable Party from time to time and any defense
arising by reason of any disability or other defense of any Other Liable Party
or by reason of the cessation from any cause whatsoever of the liability of any
Other Liable Party. Until all of the Secured Obligations shall have been paid in
full, NAI shall have no right to subrogation, reimbursement, contribution or
indemnity against any Other Liable Party and NAI waives the right to enforce any
remedy which Agent, BNPLC or any Participant has or may hereafter have against
any Other Liable Party, and waives any benefit of and any right to participate
in any other security whatsoever now or hereafter held by Agent, BNPLC or any
Participant. NAI authorizes Agent, BNPLC and the Participants, without notice or
demand and without any reservation of rights against NAI and without affecting
NAI's liability hereunder or on the Secured Obligations, from time to time to
(a) take or hold any other property of any type from any other Person as
security for the Secured Obligations, and exchange, enforce, waive and release
any or all of such other property, (b) after any Event of Default, apply or
require the application of the Collateral (in accordance with this Agreement) or
such other property in any order they may determine and to direct the order or
manner of sale thereof as they may determine, (c) renew, extend for any period,
accelerate, modify, compromise, settle or release any of the obligations of any
Other Liable Party with respect to any or all of the Secured Obligations or
other security for the Secured Obligations, and (d) release or substitute any
Other Liable Party.

                     ARTICLE XI PROVISIONS CONCERNING AGENT

     In the event of any conflict between the following and other provisions in
this Agreement, the following will control:

     Section 11.1 Appointment and Authority. BNPLC and each Participant hereby
irrevocably authorizes Agent, and Agent hereby undertakes, to take all actions
and to exercise such powers under this Agreement as are specifically delegated
to Agent by the terms hereof, together with all other powers reasonably
incidental thereto. The relationship of Agent to the Participants is only that
of one commercial bank acting as collateral agent for others, and nothing herein
shall be construed to constitute Agent a trustee or other fiduciary for any
Participant or anyone claiming through or under a Participant nor to impose on
Agent duties and obligations other than those expressly provided for in this
Agreement. With respect to any matters not expressly provided for in this
Agreement and any matters which this Agreement places within the discretion of
Agent, Agent shall not be required to exercise any discretion or take any
action, and it may request instructions from BNPLC and Participants with respect
to any such matter, in which case it shall be required to act or to refrain from
acting (and shall be fully protected and free from liability to all Participants
in so acting or refraining from acting) upon the instructions of the Majority,
as defined in the Participation Agreement, including itself as a Participant and
BNPLC; provided, however, that Agent shall not be required to take any action
which exposes it to a risk of personal liability that it considers unreasonable
or which is contrary to this Agreement or the other documents referenced herein
or to Applicable Law.

     Section 11.2 Exculpation, Agent's Reliance, Etc. Neither Agent nor any of
its directors, officers, agents, attorneys, or employees shall be liable for any
action taken or omitted to be taken by any of them under or in connection with
this Agreement, INCLUDING THEIR NEGLIGENCE OF ANY KIND, 



                                      -18-
   23

EXCEPT THAT EACH SHALL BE LIABLE FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT. Without limiting the generality of the foregoing, Agent (1) may
treat the rights of any Participant under its Participation Agreement as
continuing until Agent receives written notice of the assignment or transfer of
those rights in accordance with such Participation Agreement, signed by such
Participant and in form satisfactory to Agent; (2) may consult with legal
counsel (including counsel for NAI), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts, unless the action taken or omitted constitutes
misconduct; (3) makes no warranty or representation and shall not be responsible
for any statements, warranties or representations made in or in connection with
this Agreement or the other documents referenced herein; (4) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants or conditions of the Transaction Documents on the part of
any party thereto, or to inspect the property (including the books and records)
of any party thereto; (5) shall not be responsible to any Participant for the
due execution, legality, validity, enforceability, genuineness, sufficiency or
value of any Transaction Document or any instrument or document furnished in
connection therewith; (6) may rely upon the representations and warranties of
NAI, Participants and Deposit Takers in exercising its powers hereunder; and (6)
shall incur no liability under or in respect of the Transaction Documents by
acting upon any notice, consent, certificate or other instrument or writing
(including any telecopy, telegram, cable or telex) believed by it to be genuine
and signed or sent by the proper Person or Persons.

     Section 11.3 Participant's Credit Decisions. Each Participant acknowledges
that it has, independently and without reliance upon Agent or any other
Participant, made its own analysis of NAI and the transactions contemplated
hereby and its own independent decision to enter into the Transaction Documents
to which it is a party. Each Participant also acknowledges that it will,
independently and without reliance upon Agent or any other Participant and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Transaction Documents.

     Section 11.4 Indemnity. Each Participant agrees to indemnify Agent (to the
extent not reimbursed by NAI within ten days after demand) from and against such
Participant's Percentage of any and all Losses of any kind or nature whatsoever
which to any extent (in whole or in part) may be imposed on, incurred by, or
asserted against Agent growing out of, resulting from or in any other way
associated with any of the Collateral, the Transaction Documents and the
transactions and events (including the enforcement thereof) at any time
associated therewith or contemplated therein. THE FOREGOING INDEMNIFICATION
SHALL APPLY WHETHER OR NOT SUCH LOSSES ARE IN ANY WAY OR TO ANY EXTENT OWED, IN
WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED,
IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,
PROVIDED ONLY THAT NO PARTICIPANT SHALL BE OBLIGATED UNDER THIS SECTION TO
INDEMNIFY AGENT FOR THAT PORTION, IF ANY, OF ANY LOSS WHICH IS PROXIMATELY
CAUSED BY AGENT'S OWN INDIVIDUAL GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS
DETERMINED IN A FINAL JUDGMENT RENDERED AGAINST AGENT. Cumulative of the
foregoing, each Participant agrees to reimburse Agent promptly upon demand for
such Participant's Percentage share of any costs and expenses to be paid to
Agent by NAI hereunder to the extent that Agent is not timely reimbursed by NAI
as provided in subsection 7.2.8. As used in this Section the term "Agent" shall
refer not only to the Person designated as such in the introductory paragraph of
this Agreement, but also to each director, officer, agent, attorney, employee,
representative and Affiliate of such Person.

     Section 11.5 Agent's Rights as Participant and Deposit Taker. In its
capacity as a Participant, Banque Nationale de Paris shall have the same rights
and obligations as any Participant and may exercise such rights as though it
were not Agent. In its capacity as a Deposit Taker, Banque Nationale de Paris



                                      -19-
   24

shall have the same rights and obligations as any Deposit Taker and may exercise
such rights as though it were not Agent. Banque Nationale de Paris and any of
its Affiliates may accept deposits from, lend money to, act as Trustee under
indentures of, and generally engage in any kind of business with NAI or its
Affiliates, all as if Banque Nationale de Paris were not designated as the Agent
hereunder and without any duty to account therefor to any other Participant.

     Section 11.6 Investments. Whenever Agent in good faith determines that it
is uncertain about how to distribute any funds which it has received hereunder,
or whenever Agent in good faith determines that there is any dispute among BNPLC
and Participants about how such funds should be distributed, Agent may choose to
defer distribution of the funds which are the subject of such uncertainty or
dispute. If Agent in good faith believes that the uncertainty or dispute will
not be promptly resolved, or if Agent is otherwise required to invest funds
pending distribution, Agent shall invest such funds pending distribution, all
interest on any such investment shall be distributed upon the distribution of
such investment and in the same proportion and to the same Persons as such
investment. All moneys received by Agent for distribution to BNPLC or
Participants shall be held by Agent pending such distribution solely as Agent
hereunder, and Agent shall have no equitable title to any portion thereof.

     Section 11.7 Benefit of Article XI. The provisions of this Article (other
than the following Section 11.8) are intended solely for the benefit of Agent,
BNPLC and Participants, and NAI shall not be entitled to rely on any such
provision or assert any such provision in a claim or defense against Agent,
BNPLC or any Participant. Agent, BNPLC and Participants may waive or amend such
provisions as they desire without any notice to or consent of NAI.

     Section 11.8 Resignation. Agent may resign at any time by giving written
notice thereof to BNPLC, Participants and NAI. Upon any such resignation the
Majority (as defined in the Participation Agreement) shall have the right to
appoint a successor Agent, subject to NAI's consent, such consent not to be
unreasonably withheld. A successor must be appointed for any retiring Agent, and
such Agent's resignation shall become effective when such successor accepts such
appointment. If, within thirty days after the date of the retiring Agent's
resignation, no successor Agent has been appointed and has accepted such
appointment, then the retiring Agent may appoint a successor Agent, which shall
be a commercial bank organized or licensed to conduct a banking or trust
business under the laws of the United States of America or of any state thereof.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
the retiring Agent shall be discharged from its duties and obligations under
this Agreement. After any retiring Agent's resignation hereunder, the provisions
of this Article 10.1 shall continue to inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent.

                            ARTICLE XII MISCELLANEOUS

     Section 12.1 Provisions Incorporated From Other Operative Documents.
Reference is made to the Common Definitions and Provisions Agreement, to the
Purchase Agreement and to the Participation Agreement for a statement of the
terms thereof. Without limiting the generality of the foregoing, the provisions
of Article II of the Common Definitions and Provisions Agreement are
incorporated into this Agreement for all purposes as if set forth in this
Article.

   25

     Section 12.2 Cumulative Rights, etc. Except as herein expressly provided to
the contrary, the rights, powers and remedies of Agent, BNPLC and the
Participants under this Agreement shall be in addition to all rights, powers and
remedies given to them by virtue of any Applicable Law, any other Transaction
Document or any other agreement, all of which rights, powers, and remedies shall
be cumulative and may be exercised successively or concurrently without
impairing their respective rights hereunder. NAI waives any right to require
Agent, BNPLC or any Participant to proceed against any Person or to exhaust any
Collateral or to pursue any remedy in Agent's, BNPLC's or such Participant's
power.

     Section 12.3 Survival of Agreements. All representations and warranties of
NAI herein, and all covenants and agreements herein shall survive the execution
and delivery of this Agreement, the execution and delivery of any other
Transaction Documents and the creation of the Secured Obligations and continue
until terminated or released as provided herein.

     Section 12.4 Other Liable Party. Neither this Agreement nor the exercise by
Agent or the failure of Agent to exercise any right, power or remedy conferred
herein or by law shall be construed as relieving any Other Liable Party from
liability on the Secured Obligations or any deficiency thereon. This Agreement
shall continue irrespective of the fact that the liability of any Other Liable
Party may have ceased or irrespective of the validity or enforceability of any
other agreement evidencing or securing the Secured Obligations to which NAI or
any Other Liable Party may be a party, and notwithstanding the reorganization,
death, incapacity or bankruptcy of any Other Liable Party, or any other event or
proceeding affecting any Other Liable Party.

     Section 12.5 Termination. Following the Designated Sale Date, upon
satisfaction in full of all Secured Obligations and upon written request for the
termination hereof delivered by NAI to Agent, (i) this Agreement and the pledge
and security interest created hereby shall terminate and all rights to the
Collateral shall revert to NAI and (ii) Agent will, upon NAI's request and at
NAI's expense execute and deliver to NAI such documents as NAI shall reasonably
request to evidence such termination and release.

Banque Nationale de Paris
[address of BNP]


Re:  Pledge Agreement (the "PLEDGE AGREEMENT") dated January 20, 1999 among
          Network Appliance, Inc., BNP Leasing Corporation, Banque Nationale de
          Paris and any other financial institutions which are from time to time
          Participants under such Pledge Agreement and Banque Nationale de
          Paris, acting in its capacity as agent for BNPLC and the Participants


Gentlemen:

Capitalized terms used in this letter are intended to have the meanings assigned
to them in the Pledge Agreement referenced above. This letter constitutes notice
to you, as Agent under the Pledge Agreement, that pursuant to Section 3.1 of the
Pledge Agreement, NAI elects to change the Collateral Percentage to:

                           __________ percent (___%),

on the following Base Rent Date:

                                __________, ____

NAI expects that multiplying the new Collateral Percentage specified above
against Stipulated Loss Value of:


               ____________________________ Dollars ($__________),

will result in an expected new Minimum Collateral Value of:


               ____________________________ Dollars ($__________).


[NOTE: THE NEXT PARAGRAPH WILL BE INCLUDED ONLY IN A NOTICE OF AN INCREASE IN
THE COLLATERAL PERCENTAGE, BECAUSE OF WHICH NAI WILL BE REQUIRED TO DELIVER
ADDITIONAL CASH COLLATERAL TO SATISFY THE MINIMUM COLLATERAL VALUE REQUIREMENTS
IN SECTION 5.1 OF THE PLEDGE AGREEMENT:

Because of the increase in the Collateral Percentage which will result from this
notice and the corresponding increase in the Minimum Collateral Value, NAI will
deliver additional Cash Collateral to you as required by Section 5.1 of the
Pledge Agreement no later than 12:00 noon (San Francisco time) on the Base Rent
Date specified above, in the amount of:

   32

              ____________________________ Dollars ($__________).]

To assure you that NAI has satisfied the conditions to its right to change the
Collateral Percentage as provided in this notice, and to induce you to rely upon
this notice in discharging your responsibilities under the Pledge Agreement, NAI
certifies to you that:

     1.   NAI is giving this notice to you, BNPLC and the Participants at least
ten Business Days prior to the Base Rent Date specified above, and such Base
Rent Date is the commencement of a Base Rent Period.

     2.   No Event of Default or other event or circumstance that would,
pursuant to Section 3.2 of the Pledge Agreement, preclude NAI from designating
the new Collateral Percentage above has occurred and is continuing, and NAI does
not anticipate that on the Base Rent Date specified above there will have
occurred and be continuing any such Event of Default or other event or
circumstance.

     3.   No Mandatory Collateral Period shall be in effect as of the effective
date specified above.

NOTE: YOU SHALL BE ENTITLED TO DISREGARD THIS NOTICE IF THE STATEMENTS ABOVE ARE
NOT CORRECT. HOWEVER, WE ASK THAT YOU NOTIFY NAI IMMEDIATELY IF FOR ANY REASON
YOU BELIEVE THIS NOTICE IS DEFECTIVE.

                                  ATTACHMENT 5
                               TO PLEDGE AGREEMENT

                        EXAMPLES OF CALCULATIONS REQUIRED
                         TO AVOID A COLLATERAL IMBALANCE

     The examples below are provided to illustrate the calculations required for
allocations of Cash Collateral in a manner that will avoid a Collateral
Imbalance. The examples are not intended to reflect actual numbers under this
Agreement or actual Percentages of BNPLC or any of the Participants; nor are the
examples intended to provide a formula for the allocations that would be
appropriate in every case. The examples also reflect adjustments that would be
appropriate if the Collateral Percentage were adjusted from time to time from
and after the Base Rent Commencement Date, although this Agreement provides that
such percentage is not to increase above zero until the second anniversary of
the Effective Date (expected to be well after the Base Rent Commencement Date),
except in a Mandatory Collateral Period, during which such percentage would be
100%.

                                  EXAMPLE NO. 1

Assumptions:

1.   Two Participants ("Participant A" and "Participant B") are parties to the
     Participation Agreement with BNPLC. Participant A's Percentage is 50% and
     Participant B's Percentage is 45%, leaving BNPLC with a Percentage of 5%.

2.   On the Base Rent Commencement Date, Funding Advances (including those to
     cover Carrying Costs under the Lease) totaled $12,000,000, resulting in a
     Stipulated Loss Value of $12,000,000, allocable as follows:


                                                                              
     A.   BNPLC's Parent (providing BNPLC's share) (5%)..........................$   600,000
     B.   Participant A (50%)....................................................  6,000,000
     C.   Participant B (45%)....................................................  5,400,000
                                                                                 -----------
          TOTAL..................................................................$12,000,000



3.   The Minimum Collateral Value on the Base Rent Commencement Date was
     $7,200,000 (reflecting a Collateral Percentage of 60% times Stipulated Loss
     Value).

4.   On the Base Rent Commencement Date, NAI had delivered to Agent Cash
     Collateral of $7,200,000, equal to the Minimum Collateral Value, as
     required by Section 5.1 of this Agreement.

Allocation of Cash Collateral Required: To avoid a Collateral Imbalance under
these assumptions, Agent would be required to allocate the $7,200,000 to the
Deposit Takers for BNPLC and the Participants as follows:


                                                                              
     A.   BNPLC's Deposit Taker (5% of Minimum Collateral Value).................$  360,000
     B.   Participant A's Deposit Taker (50% of Minimum Collateral Value)........ 3,600,000
     C.   Participant B's  Deposit Taker (45% of Minimum Collateral Value)....... 3,240,000
                                                                                 ----------
          TOTAL..................................................................$7,200,000



                                  EXAMPLE NO. 2

   38

Assumptions: Assume the same facts as in Example No. 1, and in addition assume
that:

1.   Effective as of the first Base Rent Date, NAI increased its Collateral
     Percentage from 60% to 80%, raising the Minimum Collateral Value to
     $9,600,000. Because of such increase, NAI also delivered an additional
     $2,400,000 as Cash Collateral to Agent on the first Base Rent Date,
     bringing the total of all Cash Collateral delivered by NAI to $9,600,000 as
     required by Section 5.1 of this Agreement.

2.   Also effective as of the first Base Rent Date, a new Participant approved
     by NAI ("Participant C") became a party to this Agreement and the
     Participation Agreement, taking a Percentage of 20%. Simultaneously,
     Participant A and Participant B entered into supplements to the
     Participation Agreement which reduced their Percentages to 40% and 35%,
     respectively.

Allocation of Cash Collateral Required: To avoid a Collateral Imbalance under
these assumptions, Agent would be required to allocate the Cash Collateral as
required to leave the Deposit Takers for BNPLC and the Participants with the
following amounts:


                                                                              
      A.  BNPLC's Deposit Taker (5% of Minimum Collateral Value).................$  480,000
      B.  Participant A's Deposit Taker (40% of Minimum Collateral Value)........ 3,840,000
      C.  Participant B's Deposit Taker (35% of Minimum Collateral Value)........ 3,360,000
      D.  Participant C's  Deposit Taker (20% of Minimum Collateral Value)....... 1,920,000
                                                                                 ----------
          TOTAL..................................................................$9,600,000


Thus, to prevent a Collateral Imbalance, Agent would have to allocate the
$2,400,000 of additional Cash Collateral it received on the first Base Rent Date
as follows:


                                                                               
     A.   BNPLC's Deposit Taker ($480,000 less $360,000 already on deposit) ......$  120,000
     B.   Participant A's Deposit Taker ($3,840,000 less $3,600,000 already
          on deposit).............................................................   240,000
     C.   Participant B's Deposit Taker ($3,360,000 less $3,240,000 already 
          on deposit).............................................................   120,000
     D.   Participant C's  Deposit Taker ($1,920,000 less $0 already on deposit).. 1,920,000
                                                                                   ---------
          TOTAL...................................................................$2,400,000



                                  EXAMPLE NO. 3

Assumptions: Assume the same facts as in Example No. 2, except that:

1.   Instead of increasing its Collateral Percentage from 60% to 80%, NAI
     increased its Collateral Percentage to 70% on the first Base Rent Date,
     raising the Minimum Collateral Value to $8,400,000. Because of such
     increase, NAI delivered an additional $1,200,000 as additional Cash
     Collateral to Agent on the first Base Rent Date, bringing the total of all
     Cash Collateral delivered by NAI to $8,400,000 as required by Section 5.1
     of this Agreement.

Allocation of Cash Collateral Required: To avoid a Collateral Imbalance under
these assumptions, Agent would be required to allocate the Cash Collateral as
required to leave the Deposit Takers for BNPLC and the Participants with the
following amounts:


                                                                              
     A.   BNPLC's Deposit Taker (5% of Minimum Collateral Value).................$  420,000

     B.   Participant A's Deposit Taker (40% of Minimum Collateral Value)........ 3,360,000
     C.   Participant B's Deposit Taker (35% of Minimum Collateral Value)........ 2,940,000
     D.   Participant C's  Deposit Taker (20% of Minimum Collateral Value)....... 1,680,000
                                                                                 ----------
          TOTAL..................................................................$8,400,000



Thus, to prevent a Collateral Imbalance, Agent would have to allocate the
$1,200,000 of additional Cash Collateral it received on the first Base Rent Date
as follows:


                                                                                      
     A.   BNPLC's Deposit Taker ($420,000 less $360,000 already on deposit) ......$   60,000
     B.   Participant A's Deposit Taker ($3,360,000 less $3,600,000 already 
          on deposit).............................................................  (240,000)
     C.   Participant B's Deposit Taker ($2,940,000 less $3,240,000 already 
          on deposit).............................................................  (300,000)
     D.   Participant C's  Deposit Taker ($1,680,000 less $0 already on deposit).. 1,680,000
                                                                                   ---------
          TOTAL...................................................................$1,200,000



NOTE: THE NEGATIVE AMOUNTS (IN PARENTHESIS) ABOVE REPRESENT REQUIRED WITHDRAWALS
RATHER THAN DEPOSITS. AS EXAMPLE NO. 3 ILLUSTRATES, TO AVOID A COLLATERAL
IMBALANCE AGENT MAY FROM TIME TO TIME HAVE TO WITHDRAW CASH COLLATERAL HELD BY
THE DEPOSIT TAKER FOR ONE PARTICIPANT AND DEPOSIT IT IN AN ACCOUNT MAINTAINED BY
A DEPOSIT TAKER FOR ANOTHER PARTICIPANT.

          Participants

Gentlemen:

     Capitalized terms used in this letter are intended to have the meanings
assigned to them in the Pledge Agreement referenced above. This letter
constitutes notice to you, as Agent under the Pledge Agreement, that pursuant to
Section 6.1 of the Pledge Agreement, NAI requires you to withdraw from the
Accounts and return to NAI the following amount:

               ____________________________ Dollars ($__________)

on the following date:

                                __________, ____


     To assure you that NAI has satisfied the conditions to its right to require
such withdrawal, and to induce you to comply with this notice, NAI certifies to
you that:

          1.   Your withdrawal and delivery of the amount specified above to NAI
     will not cause the Value of the remaining Collateral to be less than the
     Minimum Collateral Value. After giving effect to such withdrawal, the
     Collateral remaining in the Accounts maintained by the Deposit Takers will
     be:

               ____________________________ Dollars ($__________),

   41

     and the Minimum Collateral Value on the date specified above will equal:


               ____________________________ Dollars ($__________).


     Such Minimum Collateral Value equals the Collateral Percentage of:


                           __________ percent (___%),


     times the Stipulated Loss Value of:


               ____________________________ Dollars ($__________).


          2.   NAI is giving this notice to you, BNPLC and the Participants at
     least ten days prior to the Base Rent Date specified above.

          3.   No Default or Event of Default has occurred and is continuing as
     of the date of this notice, and NAI does not anticipate that any Default or
     Event of Default will have occurred and be continuing on the date upon
     which the withdrawal is required.

          4.   NAI agrees that you may determine the Accounts from which to make
     any withdrawal required by NAI pursuant to this Section as necessary to
     prevent or mitigate any Collateral Imbalance.


     NOTE: YOU SHALL BE ENTITLED TO DISREGARD THIS NOTICE IF THE STATEMENTS
     ABOVE ARE NOT CORRECT OR IF THE DATE FOR WITHDRAWAL SPECIFIED ABOVE IS LESS
     THAN TEN DAYS AFTER YOUR RECEIPT OF THIS NOTICE. HOWEVER, WE ASK THAT YOU
     NOTIFY NAI IMMEDIATELY IF FOR ANY REASON YOU BELIEVE THIS NOTICE IS
     DEFECTIVE.



                                      -2-
   42

     Please remember that the express terms of Certificates of Deposit issued
pursuant to the Pledge Agreement require presentment of the Certificates of
Deposit seven days before Cash Collateral is to be withdrawn from the Accounts
they evidence. Accordingly, you must present Certificates of Deposit to Deposit
Takers seven days prior to the withdrawal of Cash Collateral required by this
notice. For your convenience, we have attached a letter as Annex 1 to this
notice that you might execute and send to Deposit Takers to advise them of your
intent to withdraw and of your presentment of Certificates of Deposit as
required in connection therewith. The attached letter also sets forth the
amounts NAI believes you must withdraw from each Account to avoid a Collateral
Imbalance.
