                                (PHASE V - LAND)


        This PLEDGE AGREEMENT (PHASE V - LAND) (this "AGREEMENT") is made as of
March 1, 2000 (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 (Phase V - Land) dated as of the Effective Date (the "COMMON
DEFINITIONS AND PROVISIONS AGREEMENT (PHASE V - LAND)"); and (ii) a Purchase
Agreement (Phase V - Land) dated as of the Effective Date (the "PURCHASE
AGREEMENT"), pursuant to which NAI has agreed to make a "SUPPLEMENTAL PAYMENT"
(as defined in the Common Definitions and Provisions Agreement (Phase V -
Land)), in consideration of the rights granted to NAI by the Purchase Agreement.

        B. Pursuant to a Participation Agreement dated as of March 1, 2000 (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 (Phase
V - Land)), 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 BNPLC 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:

defined herein shall have the same meanings herein as set forth in the Common
Definitions and Provisions Agreement (Phase V - Land). All terms used in this
Agreement which are defined in the UCC and not



                                      -1-

        Taker into which Cash Collateral may be deposited at any time, excluding

                "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.

                "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 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

                "CERTIFICATE OF DEPOSIT" shall mean a certificate of deposit

        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

        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

        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 Part

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

                        (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 Land Lease an
                amount equal to interest at the Default Rate (as defined in the
                Land 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



                                      -3-
   8

                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
                Land 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 Land 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

                        (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 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.



                                      -4-

                "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 any right of setoff which
        arises without agreement in the ordinary course of business. "Lien" also
        means any filed financing statement, any registration with an issuer of
        uncertificated securities, or any other arrangement which would serve to
        perfect a Lien described in the preceding sentence, regardless of
        whether such financing statement is filed, such registration is made, or
        such arrangement is undertaken before or after such Lien exists.

                "MATERIAL LEASE DEFAULT" shall mean any of the following:

        (1) any "Event of Default" under and as defined in the Land Lease,
        including any such Event of Default consisting of a failure of NAI to
        comply with the requirements of Exhibit I attached to the Land Lease;
        and

        (2) (a) any failure of NAI to make any payment required by and when
        first due under the Land Lease, regardless of whether any period
        provided in the Land Lease for the cure of such failure by NAI shall
        have expired, and (b) any other 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" under and as
        defined in the Land 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
        include any noncompliance, the correction of which has been requested by
        a governmental authority, or because of which a threat of action against
        the Property or BNPLC has been asserted by a governmental authority.)

        1.4 Amendment of Defined Instruments. Unless the context otherwise
requires or unless otherwise provided herein, references in this Agreement to a
particular agreement, instrument or document (including references to the Land
Lease, Purchase Agreement and Participation Agreement) also refer to and include

Attachments, Articles, Sections, subsections, and other subdivisions refer to
the Attachments, Articles, Sections, subsections and other subdivisions of this
Agreement unless expressly provided otherwise. Titles appearing at the beginning
of any subdivision are for convenience only and do not constitute any part of
any such subdivision and shall be disregarded in construing the language
contained in this Agreement. The words "this Agreement", "herein", "hereof",
"hereby", "hereunder" and words of similar import refer to this Agreement as a
whole and not to any particular subdivision unless expressly so limited. The
phrases "this Article," "this Section" and "this subsection" and similar phrases
refer only to the Articles, Sections or subsections hereof in which the phrase
occurs. The word "or" is not exclusive, and the word "including" (in all of its



                                      -7-

                          ARTICLE II SECURITY INTEREST

        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.

        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

        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



                                      -8-
   13

Percentage so designated shall not become effective, however, until the
commencement of the later of (A) the first Base Rent Period to commence on or
after the first Business Day of September, 2001, or (B) the next following Base
Rent Period which is at least ten Business Days after the receipt of such notice
by Agent, BNPLC and the Participants. Further, after the first change in the
Collateral Percentage resulting from a designation by NAI of a Collateral
Percentage greater than zero percent (0%), any subsequent change resulting from
NAI's designation of a new Collateral Percentage shall not become effective
before the first Business Day of the first Base Rent Period that commences at
least ninety days after the effective date of the last preceding change in the
Collateral 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
this Section (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.

        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; or

                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 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.

        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

        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



                                      -9-
   14

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 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.

        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.

        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



                                      -10-
   15

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.

        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.

        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.

        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.

        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.

        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



                                      -11-
   16

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.

        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.

        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 "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

        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 Land Lease as received on the next following
Business



                                      -12-
   17

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.

        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.

        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
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.

        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



                                      -13-
   18

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.

        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.

        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:

        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.

        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



                                      -15-
   20

                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.

        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 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.

        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

        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.



                                      -16-
   21

                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
(Phase V - Land) 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.

        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, (C) cause the security interest of
Agent in any Collateral consisting of securities to be recorded or registered in
the books of any financial intermediary or clearing corporation requested by
Agent, and (D) reimburse Agent upon request for any legal opinion Agent may
elect to obtain from a nationally recognized commercial law firm authorized to
practice in New York concerning the enforceability, first priority and
perfection of Agent's security interest in any Collateral maintained in New
York, if BNPLC or any Participant should at any time elect to use a Deposit
Taker that will maintain one or more Accounts in New York.

                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).



                                      -17-
   22

                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 Land 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

        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 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



                                      -18-
   23

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

        9.1 Remedies. In addition to all other rights and remedies granted to
Agent, BNPLC or the Participants by this Agreement, the Land 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.


                            ARTICLE X OTHER RECOURSE

        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



                                      -19-
   24

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:

        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.

        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, 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



                                      -20-
   25

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 (7) 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.

        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.

        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.



                                      -21-
   26

        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 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.

        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.

        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.

        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 11 shall
continue to inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent.

   27

                            ARTICLE XII MISCELLANEOUS

        12.1 Provisions Incorporated From Other Operative Documents. Reference
is made to the Common Definitions and Provisions Agreement (Phase V - Land), 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 (Phase V -
Land) are incorporated into this Agreement for all purposes as if set forth in
this Article.

        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.

        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.

        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.

        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 (Phase V - Land) (the "PLEDGE
                        AGREEMENT") dated March 1, 2000 among Network Appliance,
                        Inc., BNP Leasing Corporation, Banque Nationale de Paris
                        and any other financial institutions which are from time

                        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 ($__________).



                                      -1-
   35

[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:


                     ____________________________ 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.

separate and apart from all other property and funds of NAI and all other
Persons and to permit no other funds to be deposited or credited to the
Account(s);

                (b) make a notation in its books and records of the interest of

credited thereto are subject to a pledge and security interest in favor of
Agent;

                (c) issue and redeem Certificates of Deposit evidencing the

the Collateral; and

                (e) upon receipt of notice from Agent that an Event of Default
has occurred, transfer and deliver to Agent or its nominee, together with all
necessary endorsements, all or such portion of the Collateral held by Deposit
Taker as Agent shall direct; provided, however, that in connection therewith the
Deposit Taker may require compliance by Agent with the provisions in Section 5.4

Deposit which evidence the Account(s).

        5. NAI and Agent agree that (a) the possession by Deposit Taker of all

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 Section 9305, 8313 or 8213 of the UCC (as the case may be), and (b)
notifications by Deposit Taker to other Persons holding any such property, and
Acknowledgments, receipts or confirmations from such Persons delivered to
Deposit Taker, shall be deemed notifications to, or Acknowledgments, receipts or
confirmations from, financial intermediaries, bailees or agents (as applicable)
of the Deposit Taker for the benefit of Agent for the purposes of perfecting
such security interests under applicable law.

        6. As contemplated by the Pledge Agreement, please acknowledge Deposit
Taker's receipt of, and consent to, this notice and confirm the representations

                               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 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 Land 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.



                                      -1-
   42

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..


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)

        D.     Participant C's  Deposit Taker ($1,680,000 less $0 already

               TOTAL................................................................   $1,200,000

Gentlemen:

        Capitalized terms used in this letter are intended to have the meanings
assigned to them in the Pledge Agreement (Phase V - Land) referenced above (the
"PLEDGE AGREEMENT"). 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 ($__________),



                                      -1-
   46

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.

        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.

Pledge Agreement, that pursuant to Section 6.4 of the Pledge Agreement, NAI

receive this notice.

To assure you that NAI has the right to require such withdrawal, and to induce
you to comply with this notice, NAI certifies to you that the Deposit Taker

SATISFIED, ALL IN SUFFICIENT DETAIL TO PERMIT THE PARTICIPANT FOR WHOM SUCH
DEPOSIT TAKER HAS BEEN MAINTAINING AN ACCOUNT TO RESPOND IF IT BELIEVES THAT NAI
IS IN ERROR.]

        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 the
Deposit Taker specified above 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 such Deposit
Taker to advise it 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 amount NAI believes you must withdraw to comply with Section
6.4 of the Pledge Agreement.

May 12, 2001                                   No
August 16, 2001                               Yes
November 11, 2001                              No

February 15, 2003                              No


Under these assumptions, the entire period from February 15, 2001 to February
18, 2002 falls within one or more Mandatory Collateral Periods. Also, the entire
period commencing May 14, 2002 and ending February 15, 2003 falls within one or
more Mandatory Collateral Periods. The period from February 18, 2002 to May 14,
2002 does not constitute Mandatory Collateral Period.

governmental approvals, rights, privileges and franchises necessary for the
conduct of its business; or fail to comply with the provisions of all documents
