                               PURCHASE AGREEMENT
                                (PHASE IV - LAND)

       This PURCHASE AGREEMENT (PHASE IV - LAND) (this "Agreement"), by and
between BNP LEASING CORPORATION, a Delaware corporation ("BNPLC"), and NETWORK
APPLIANCE, INC., a California corporation ("NAI"), is made and dated as of
October 2, 2000, the Effective Date. ("Effective Date" and other capitalized
terms used and not otherwise defined in this Agreement are intended to have the
meanings assigned to them in the Common Definitions and Provisions Agreement
(Phase IV - Land) executed by BNPLC and NAI contemporaneously with this
Agreement. By this reference, the Common Definitions and Provisions Agreement
(Phase IV - Land) is incorporated into and made a part of this Agreement for all
purposes.)

                                    RECITALS

       NAI and BNPLC previously executed that Purchase Agreement (Phase IV Land)
dated as of December 20, 1000 (the "Prior Purchase Agreement"). NAI and BNPLC
have agreed to amend, restate and replace the Prior Purchase Agreement with this
Agreement as provided in Paragraph 10 below.

       Pursuant to the Existing Contract, which covers the Land described in
Exhibit A, BNPLC has acquired the Land and any appurtenances thereto from
Seller. Pursuant to the Lease Agreement (Phase IV - Land) executed by BNPLC and
NAI contemporaneously with this Agreement (the "Land Lease"), BNPLC is leasing
the Land to NAI. (All of BNPLC's interests, including those created by the
documents delivered at the closing under the Existing Contracts, in the Land and
in all other real and personal property from time to time covered by the Land
Lease and included within the "Property" as defined therein are hereinafter
collectively referred to as the "Property". The Property does not include the
Improvements, it being understood that the Other Purchase Agreement constitutes
a separate agreement providing for the possible sale of the Improvements and the
appurtenances thereto, and only the Improvements and the appurtenances thereto,
from BNPLC to NAI or a third party designated by NAI.)

       NAI and BNPLC have reached agreement upon the terms and conditions upon
which NAI will purchase or arrange for the purchase of the Property, and by this
Agreement they desire to evidence such agreement.

                                   AGREEMENTS

       1.     NAI'S OPTIONS AND OBLIGATIONS ON THE DESIGNATED SALE DATE.

              (A) Right to Purchase; Right and Obligation to Remarket. Whether
or not an Event of Default shall have occurred and be continuing or the Land
Lease shall have been terminated, but subject to Paragraph 4 below:

                     (1) NAI shall have the right (the "Purchase Option") to
       purchase or cause an Affiliate of NAI to purchase the Property and
       BNPLC's interest in Escrowed



<PAGE>   5

       Proceeds, if any, on the Designated Sale Date for a cash price equal to
       the Break Even Price (as defined below).

                     (2) If neither NAI nor an Affiliate of NAI purchases the
       Property and BNPLC's interest in any Escrowed Proceeds on the Designated
       Sale Date as provided in the preceding subparagraph 1.(A)(1), then NAI
       shall have the following rights and obligations (collectively, "NAI's
       Initial Remarketing Rights and Obligations"):

                            (a) First, NAI shall have the right (but not the
              obligation) to cause an Applicable Purchaser who is not an
              Affiliate of NAI to purchase the Property and BNPLC's interest in
              any Escrowed Proceeds on the Designated Sale Date for a cash
              purchase price (the "Third Party Price") determined as provided
              below. If, however, the Break Even Price exceeds the sum of any
              Third Party Price tendered or to be tendered to BNPLC by an
              Applicable Purchaser and any Supplemental Payment paid by NAI as
              described below, then BNPLC may affirmatively elect to decline
              such tender from the Applicable Purchaser and to keep the Property
              and any Escrowed Proceeds rather than sell to the Applicable
              Purchaser pursuant to this subparagraph (a "Voluntary Retention of
              the Property").

                            (b) Second, if the Third Party Price actually paid
              by an Applicable Purchaser to BNPLC on the Designated Sale Date
              exceeds the Break Even Price, NAI shall be entitled to such
              excess, subject, however, to BNPLC's right to offset against such
              excess any and all sums that are then due from NAI to BNPLC under
              the other Operative Documents.

                            (c) Third, if for any reason whatsoever (including a
              Voluntary Retention of the Property or a decision by NAI not to
              exercise its right to purchase or cause an Applicable Purchaser to
              purchase from BNPLC as described above) neither NAI nor an
              Applicable Purchaser pays a net cash price to BNPLC on the
              Designated Sale Date equal to or in excess of the Break Even Price
              in connection with a sale of the Property and BNPLC's interest in
              any Escrowed Proceeds pursuant to this Agreement, then NAI shall
              have the obligation to pay to BNPLC on the Designated Sale Date a
              supplemental payment (the "Supplemental Payment") equal to the
              lesser of (1) the amount by which the Break Even Price exceeds
              such net cash price (if any) actually received by BNPLC on the
              Designated Sale Date (such excess being hereinafter called a
              "Deficiency") or (2) the Maximum Remarketing Obligation. As used
              herein, the "Maximum Remarketing Obligation" means a dollar amount
              determined in accordance with the following provisions:

                                   1) The "Maximum Remarketing Obligation" will
                     equal the product of (i) Stipulated Loss Value on the
                     Designated Sale Date, times (ii) 100% minus the Residual
                     Risk Percentage, provided that both of the following
                     conditions are satisfied:



                                       2
<PAGE>   6

              (x) NAI shall not have elected to accelerate the Designated Sale
       Date as provided in clause (2) of the definition of Designated Sale Date
       in the Common Definitions and Provisions Agreement (Phase IV - Land).

              (y) No Event of Default, other than an Issue 97-1
       Non-performance-related Subjective Event of Default, shall occur on or be
       continuing on the Designated Sale Date.

                                   2) If either of the conditions listed in
                     subparagraph 1) preceding are not satisfied, the "Maximum
                     Remarketing Obligation" will equal the Break Even Price.

If any Supplemental Payment or other amount payable to BNPLC pursuant to this
subparagraph 1.(A) is not actually paid to BNPLC on the Designated Sale Date,
NAI shall pay interest on the past due amount computed at the Default Rate from
the Designated Sale Date.

              (B) Determinations Concerning Price.

                     (1) Determination of the Break Even Price. As used herein,
       "Break Even Price" means an amount equal, on the Designated Sale Date, to
       Stipulated Loss Value, plus all out-of-pocket costs and expenses
       (including appraisal costs, withholding taxes (if any) not constituting
       Excluded Taxes, and Attorneys' Fees) incurred by BNPLC in connection with
       any sale of BNPLC's interests in the Property under this Agreement or in
       connection with collecting payments due hereunder, but less the aggregate
       amounts (if any) of Direct Payments to Participants and Deposit Taker
       Losses (other than Excluded Deposit Taker Losses).

                     (2) Determination of Third Party Price. The Third Party
       Price required of any Applicable Purchaser purchasing from BNPLC under
       subparagraph 1.(A)(2)(a) will be determined as follows:

                            (a) NAI may give a notice (a "REMARKETING NOTICE")
              to BNPLC and to each of the Participants no earlier than one
              hundred twenty days before the Designated Sale Date and no later
              than ninety days before the Designated Sale Date, specifying an
              amount as the Third Party Price that NAI believes in good faith to
              constitute reasonably equivalent value for the Property and any
              Escrowed Proceeds. Once given, a Remarketing Notice shall not be
              rescinded or modified without BNPLC's written consent.

                            (b) If BNPLC believes in good faith that the Third
              Party Price specified by NAI in a Remarketing Notice does not
              constitute reasonably equivalent value for the Property and any
              Escrowed Proceeds, BNPLC may at any time before sixty days prior
              to the Designated Sale Date respond to the Remarketing Notice with
              a notice back to NAI, objecting to the Third Party Price so
              specified by NAI. If BNPLC receives a Remarketing Notice, yet does
              not respond with an objection as provided in the preceding
              sentence, the Third Party Price suggested by NAI in the
              Remarketing Notice will be the Third Party Price for purposes of
              this Agreement. If, however, BNPLC does respond with an objection
              as provided in this subparagraph, and if NAI and BNPLC do not



                                       3
<PAGE>   7

              otherwise agree in writing upon a Third Party Price, then the
              Third Party Price will be the lesser of (I) fair market value of
              the Property, plus the amount of any Escrowed Proceeds, as
              determined by a professional independent appraiser satisfactory to
              BNPLC, or (II) the Break Even Price.

                            (c) If for any reason, including an acceleration of
              the Designated Sale Date as provided in the definition thereof in
              the Common Definitions and Provisions Agreement (Phase IV - Land),
              NAI does not deliver a Remarketing Notice to BNPLC within the time
              period specified above, then the Third Party Price will be an
              amount determined in good faith by BNPLC as constituting
              reasonably equivalent value for the Property and any Escrowed
              Proceeds, but in no event more than the Break Even Price.

If any payment to BNPLC by an Applicable Purchaser hereunder is held to
constitute a preference or a voidable transfer under Applicable Law, or must for
any other reason be refunded by BNPLC to the Applicable Purchaser or to another
Person, and if such payment to BNPLC reduced or had the effect of reducing a
Supplemental Payment or increased or had the effect of increasing any excess
sale proceeds paid to NAI pursuant to subparagraph 1(A)(2)(b) or pursuant to
subparagraph 2.(D), then NAI shall pay to BNPLC upon demand an amount equal to
the reduction of the Supplemental Payment or to the increase of the excess sale
proceeds paid to NAI, as applicable, and this Agreement shall continue to be
effective or shall be reinstated as necessary to permit BNPLC to enforce its
right to collect such amount from NAI.

              (C) Designation of the Purchaser. To give BNPLC the opportunity
before the Designated Sale Date to prepare the deed and other documents that
BNPLC must tender pursuant to Paragraph 3 (collectively, the "SALE CLOSING
DOCUMENTS"), NAI must, by a notice to BNPLC given at least seven days prior to
the Designated Sale Date, specify irrevocably, unequivocally and with
particularity the party who will purchase the Property in order to satisfy the
obligations of NAI set forth in subparagraph 1(A). If for any reason NAI fails
to so specify a party who will in accordance with the terms and conditions set
forth herein purchase the Property (be it NAI itself, an Affiliate of NAI or
another Applicable Purchaser), BNPLC shall be entitled to postpone the tender of
the Sale Closing Documents until a date after the Designated Sale Date and not
more than twenty days after NAI finally does so specify a party, but such
postponement will not relieve or postpone the obligation of NAI to make a
Supplemental Payment on the Designated Sale Date as provided in Paragraph
1.(A)(2)(c).

              (D) Effect of the Purchase Option and NAI's Initial Remarketing
Rights and Obligations on Subsequent Title Encumbrances. Any conveyance of the
Property to NAI or any Applicable Purchaser pursuant to this Paragraph 1.(A)
shall cut off and terminate any interest in the Land or other Property claimed
by, through or under BNPLC, including any interest claimed by the Participants
and including any Liens Removable by BNPLC (such as, but not limited to, any
judgment liens established against the Property because of a judgment rendered
against BNPLC and any leasehold or other interests conveyed by BNPLC in the
ordinary course of BNPLC's business), but not including personal obligations of
NAI to BNPLC under the Land Lease or other Operative Documents (including
obligations arising under the indemnities therein). Anyone accepting or taking
any interest in the Property by or through BNPLC after the date of this
Agreement shall acquire such interest subject to the Purchase Option and NAI's



                                       4
<PAGE>   8

Initial Remarketing Rights and Obligations. Further, NAI and any Applicable
Purchaser shall be entitled to pay any payment required by this Agreement for
the purchase of the Property directly to BNPLC notwithstanding any prior
conveyance or assignment by BNPLC, voluntary or otherwise, of any right or
interest in this Agreement or the Property, and neither NAI nor any Applicable
Purchaser shall be responsible for the proper distribution or application of any
such payments by BNPLC; and any such payment to BNPLC shall discharge the
obligation of NAI to cause such payment to all Persons claiming an interest in
such payment. Contemporaneously with the execution of this Agreement, the
parties shall record a memorandum of this Agreement for purposes of effecting
constructive notice to all Persons of NAI's rights under this Agreement,
including its rights under this subparagraph.

              (E) Security for the Purchase Option and NAI's Initial Remarketing
Rights and Obligations. To secure BNPLC's obligation to sell the Property
pursuant to Paragraph 1.(A) and to pay any damages to NAI caused by a breach of
such obligations, including any such breach caused by a rejection or termination
of this Agreement in any bankruptcy or insolvency proceeding instituted by or
against BNPLC, as debtor, BNPLC does hereby grant to NAI a lien and security
interest against all rights, title and interests of BNPLC from time to time in
and to the Land and other Property. NAI may enforce such lien and security
interest judicially after any such breach by BNPLC, but not otherwise.
Contemporaneously with the execution of this Agreement, NAI and BNPLC will
execute a memorandum of this Agreement which is in recordable form and which
specifically references the lien granted in this subparagraph, and NAI shall be
entitled to record such memorandum at any time prior to the Designated Sale
Date.

              (F) Delivery of Books and Records If BNPLC Retains the Property.
Unless NAI or its Affiliate or another Applicable Purchaser purchases the
Property pursuant to Paragraph 1.(A), promptly after the Designated Sale Date
NAI shall deliver to BNPLC copies of books and records of NAI which will be
necessary or useful to any future owner's or occupant's use of the Property in
the manner permitted by the Land Lease.

       2.     NAI'S RIGHTS AND OPTIONS AFTER THE DESIGNATED SALE DATE.

              (A) NAI's Extended Right to Remarket. During the two years
following the Designated Sale Date ("NAI'S EXTENDED REMARKETING PERIOD"), NAI
shall have the right ("NAI'S EXTENDED REMARKETING RIGHT") to cause an Applicable
Purchaser who is not an Affiliate of NAI to purchase the Property for a cash
purchase price not below the lesser of (I) the Minimum Extended Remarketing
Price (as defined below), or (II) if applicable, the Third Party Target Price
(as defined below) specified in any Third Party Sale Notice (as defined below)
given by BNPLC pursuant to subparagraph 2.(C)(2) within the ninety days prior to
the date (the "FINAL SALE DATE") upon which BNPLC receives such purchase price
from the Applicable Purchaser. NAI's Extended Remarketing Right shall, however,
be subject to all of the following conditions:

                     (1) The Property and BNPLC's interest in Escrowed Proceeds,
       if any, shall not have been sold on the Designated Sale Date as provided
       in Paragraph 1.



                                       5
<PAGE>   9

                     (2) No Voluntary Retention of the Property shall have
       occurred as described in subparagraph 1.(A)(2)(a).

                     (3) NAI's Extended Remarketing Right shall not have been
       terminated pursuant to subparagraph 4.(D) below because of NAI's failure
       to make any Supplemental Payment required on the Designated Sale Date.

                     (4) NAI's Extended Remarketing Right shall not have been
       terminated by BNPLC pursuant to subparagraph 4.(E) below to facilitate
       BNPLC's sale of the Property to a third party in accordance with
       subparagraph 2.(C).

                     (5) At least thirty days prior to the Final Sale Date, NAI
       shall have notified BNPLC of (x) the date proposed by NAI as the Final
       Sale Date (which must be a Business Day), (y) the full legal name of the
       Applicable Purchaser and such other information as will be required to
       prepare the Sale Closing Documents, and (z) the amount of the purchase
       price that the Applicable Purchaser will pay (consistent with the minimum
       required pursuant to the other provisions of this subparagraph 2.(A)) for
       the Property.

              (B) Definition of Minimum Extended Remarketing Price. As used
herein, "MINIMUM EXTENDED REMARKETING PRICE" means an amount equal to the sum of
the following:

                     (1) the amount by which the Break Even Price computed on
       the Designated Sale Date exceeds any Supplemental Payment actually paid
       to BNPLC on the Designated Sale Date, together with interest on such
       excess computed at the Default Rate from the period commencing on the
       Designated Sale Date and ending on the Final Sale Date, plus

                     (2) all out-of-pocket costs and expenses (including
       withholding taxes [if any], other than Excluded Taxes, and Attorneys'
       Fees) incurred by BNPLC in connection with the sale to the Applicable
       Purchaser, to the extent not already included in the computation of Break
       Even Price, and plus

                     (3) the sum of all Impositions, insurance premiums and
       other Losses of every kind suffered or incurred by BNPLC or any other
       Interested Party with respect to the ownership, operation or maintenance
       of the Property on or after the Designated Sale Date (except to the
       extent already reimbursed by any lessee of the Property after the
       Designated Sale Date), together with interest on such Impositions,
       insurance premiums and other Losses computed at the Default Rate from the
       date paid or incurred to the Final Sale Date.

If, however, Losses described in the preceding clause (3) consist of claims
against BNPLC or another Interested Party that have not been liquidated prior to
the Final Sale Date (and, thus, such Losses have yet to be fixed in amount as of
the Final Sale Date), then NAI may elect to exclude any such Losses from the
computation of the Minimum Extended Remarketing Price by providing to BNPLC, for
the benefit of BNPLC and other Interested Parties, a written agreement to
indemnify and defend BNPLC and other Interested Parties against such Losses. To
be effective hereunder for purposes of reducing the Minimum Extended Remarketing
Price (and,



                                       6
<PAGE>   10

thus, the Break Even Price), any such written indemnity must be fully executed
and delivered by NAI on or prior to the Final Sale Date, must include provisions
comparable to subparagraphs 5(c)(ii), (iii), (iv) and (v) of the Land Lease and
otherwise must be in form and substance satisfactory to BNPLC.

              (C) BNPLC's Right to Sell. After the Designated Sale Date, if the
Property has not already been sold by BNPLC pursuant to Paragraph 2 or this
Paragraph 2, BNPLC shall have the right to sell the Property or offer the
Property for sale to any third party on any terms believed to be appropriate by
BNPLC in its sole good faith business judgment; provided, however, that so long
as the conditions to NAI's Extended Remarketing Rights specified in subparagraph
2.(A) continue to be satisfied:

                     (1) BNPLC shall not sell the Property to an Affiliate of
       BNPLC on terms less favorable than those which BNPLC would require from a
       prospective purchaser not an Affiliate of BNPLC;

                     (2) If BNPLC receives or desires to make a written proposal
       (whether in the form of a "letter of intent" or other nonbinding
       expression of interest or in the form of a more definitive purchase and
       sale agreement) for a sale of the Property to a prospective purchaser (a
       "THIRD PARTY SALE PROPOSAL"), and if on the basis of such Third Party
       Sale Proposal BNPLC expects to enter into or to pursue negotiations for a
       definitive purchase and sale agreement with the prospective purchaser,
       then prior to executing any such definitive agreement, BNPLC shall submit
       the Third Party Sale Proposal to NAI with a notice (the "THIRD PARTY SALE
       NOTICE") explaining that (A) BNPLC is then prepared to accept a price not
       below an amount specified in such Third Party Sale Notice (the "THIRD
       PARTY TARGET Price") if BNPLC and the prospective purchaser reach
       agreement on other terms and conditions to be incorporated into a
       definitive purchase and sale agreement, and (B) NAI's Extended
       Remarketing Right may be terminated pursuant to subparagraph 4.(E) of
       this Agreement unless NAI causes an Applicable Purchaser to consummate a
       purchase of the Property pursuant to this Paragraph 2 within ninety days
       after the date of such Third Party Sale Notice.

              (D) NAI's Right to Excess Sales Proceeds. If the cash price
actually paid by any third party purchasing the Property from BNPLC during NAI's
Extended Remarketing Period, including any price paid by an Applicable Purchaser
purchasing from BNPLC pursuant to this Paragraph 2, exceeds the Minimum Extended
Remarketing Price, then NAI shall be entitled to the excess; provided, that
BNPLC may offset and retain from the excess any and all sums that are then due
and unpaid from NAI to BNPLC under any of the Operative Documents.

              (E) Permitted Transfers During NAI's Extended Remarketing Period.
Any "Permitted Transfer" described in clause (6) of the definition thereof in
the Common Definitions and Provisions Agreement (Phase IV - Land) to an
Affiliate of BNPLC or that covers BNPLC's entire interest in the Land will be
subject to NAI's Extended Remarketing Right if, at the time of the Permitted
Transfer, NAI's Extended Remarketing Right has not expired or been terminated as
provided herein. Any other Permitted Transfer described in clause (6) of the
definition thereof, however, will not be subject to NAI's Extended Remarketing
Right. Thus, for example, BNPLC's conveyance of a utility easement or space
lease more than thirty days after the



                                       7
<PAGE>   11

Designated Sale Date to a Person not an Affiliate of BNPLC shall not be subject
to NAI's Extended Remarketing Right, though following the conveyance of the
lesser estate, NAI's Extended Remarketing Right may continue to apply to BNPLC's
remaining interest in the Land and any Personal Property.

       3. TERMS OF CONVEYANCE UPON PURCHASE. As necessary to consummate any sale
of the Property to NAI or an Applicable Purchaser pursuant to this Agreement,
BNPLC must, subject to any postponement permitted by subparagraph 1.(C),
promptly after the tender of the purchase price and any other payments to BNPLC
required pursuant to Paragraph 1 or Paragraph 2, as applicable, convey all of
BNPLC's right, title and interest in the Land and other Property to NAI or the
Applicable Purchaser, as the case may be, by BNPLC's execution, acknowledgment
(where appropriate) and delivery of the Sale Closing Documents. Such conveyance
by BNPLC will be subject only to the Permitted Encumbrances and any other
encumbrances that do not constitute Liens Removable by BNPLC. However, such
conveyance shall not include the rights of BNPLC or other Interested Parties
under the indemnities provided in the Operative Documents, including rights to
any payments then due from NAI under the indemnities or that may become due
thereafter because of any expense or liability incurred by BNPLC or another
Interested Party resulting in whole or in part from events or circumstances
occurring or alleged to have occurred before such conveyance. All costs, both
foreseen and unforeseen, of any purchase by NAI or an Applicable Purchaser
hereunder shall be the responsibility of the purchaser. The Sale Closing
Documents used to accomplish such conveyance shall consist of the following: (1)
a Corporation Grant Deed in the form attached as Exhibit B-1 or Exhibit B-2 or
Exhibit B-4, as required by Exhibit B, (2) if required by Exhibit B, a Ground
Lease in the form attached as Exhibit B-3, which NAI or the Applicable Purchase
must execute and return to BNPLC, (3) a Bill of Sale and Assignment in the form
attached as Exhibit C, (4) an Acknowledgment of Disclaimer of Representations
and Warranties, in the form attached as Exhibit D, which NAI or the Applicable
Purchaser must execute and return to BNPLC, (5) a Secretary's Certificate in the
form attached as Exhibit E, and (6) a certificate concerning tax withholding in
the form attached as Exhibit F. If for any reason BNPLC fails to tender the Sale
Closing Documents as required by this Paragraph 3, BNPLC may cure such refusal
at any time before thirty days after receipt of a demand for such cure from NAI.

       4.     SURVIVAL AND TERMINATION OF THE RIGHTS AND OBLIGATIONS OF NAI AND
              BNPLC.

              (A) Status of this Agreement Generally. Except as expressly
provided herein, this Agreement shall not terminate; nor shall NAI have any
right to terminate this Agreement; nor shall NAI be entitled to any reduction of
the Break Even Price, any Deficiency, the Maximum Remarketing Obligation, any
Supplemental Payment or the Minimum Extended Remarketing Price hereunder; nor
shall the obligations of NAI to BNPLC under Paragraph 1 be affected, by reason
of (i) any damage to or the destruction of all or any part of the Property from
whatever cause (though it is understood that NAI will receive any remaining
Escrowed Proceeds yet to be applied as provided in the Land Lease that may
result from such damage if NAI purchases the Property and the Escrowed Proceeds
as herein provided), (ii) the taking of or damage to the Property or any portion
thereof by eminent domain or otherwise for any reason (though it is understood
that NAI will receive any remaining Escrowed Proceeds yet to be applied as
provided in the Land Lease that may result from such taking or damage if NAI



                                       8
<PAGE>   12

purchases the Property and the Escrowed Proceeds as herein provided), (iii) the
prohibition, limitation or restriction of NAI's use of all or any portion of the
Property or any interference with such use by governmental action or otherwise,
(iv) any eviction of NAI or any party claiming under NAI by paramount title or
otherwise, (v) NAI's prior acquisition or ownership of any interest in the
Property, (vi) any default on the part of BNPLC under this Agreement, the Land
Lease or any other agreement to which BNPLC is a party, or (vii) any other
cause, whether similar or dissimilar to the foregoing, any existing or future
law to the contrary notwithstanding. It is the intention of the parties hereto
that the obligations of NAI to make payment to BNPLC hereunder shall be separate
and independent covenants and agreements from BNPLC's obligations under this
Agreement or any other agreement between BNPLC and NAI; provided, however, that
nothing in this subparagraph shall excuse BNPLC from its obligation to tender
the Sale Closing Documents in substantially the form attached hereto as exhibits
when required by Paragraph 3. Further, nothing in this subparagraph shall be
construed as a waiver by NAI of any right NAI may have at law or in equity to
the following remedies, whether because of BNPLC's failure to remove a Lien
Removable by BNPLC or because of any other default by BNPLC under this
Agreement: (i) the recovery of monetary damages, (ii) injunctive relief in case
of the violation, or attempted or threatened violation, by BNPLC of any of the
express covenants, agreements, conditions or provisions of this Agreement which
are binding upon BNPLC, or (iii) a decree compelling performance by BNPLC of any
of the express covenants, agreements, conditions or provisions of this Agreement
which are binding upon BNPLC.

              (B) Intentionally Deleted.

              (C) Intentionally Deleted.

              (D) Automatic Termination of NAI's Rights. Without limiting
BNPLC's right to enforce NAI's obligation to pay any Supplemental Payment or
other amounts required by this Agreement, the rights of NAI (to be distinguished
from the obligations of NAI) included in NAI's Initial Remarketing Rights and
Obligations, the Purchase Option and NAI's Extended Remarketing Rights shall all
terminate automatically if NAI shall fail to pay the full amount of any
Supplemental Payment required by subparagraph 1.(A)(2)(c) on the Designated Sale
Date or if BNPLC shall elect a Voluntary Retention of the Property as provided
in subparagraph 1.(A)(2)(a). However, notwithstanding anything in this
subparagraph to the contrary, even after a failure to pay any required
Supplemental Payment on the Designated Sale Date, NAI may nonetheless tender to
BNPLC the full Break Even Price and all amounts then due under the Operative
Documents, together with interest on the total Break Even Price computed at the
Default Rate from the Designated Sale Date to the date of tender, on any
Business Day within thirty days after the Designated Sale Date, and if presented
with such a tender within thirty days after the Designated Sale Date, BNPLC must
accept it and promptly thereafter deliver any Escrowed Proceeds and the Sale
Closing Documents listed in Paragraph 3 to NAI.

              (E) Termination of NAI's Extended Remarketing Rights to Permit a
Sale by BNPLC. At any time more than ninety days after BNPLC has delivered a
Third Party Sale Notice to NAI as described in subparagraph 2.(C)(2), BNPLC may
terminate NAI's Extended Remarketing Rights contemporaneously with the
consummation of a sale of the Property by BNPLC to any third party (be it the
prospective purchaser named in the Third Party Sale Notice or another third
party) at a price equal to or in excess of the Third Party Target Price
specified in



                                       9
<PAGE>   13

the Third Party Sale Notice, so as to permit the sale of the Property
unencumbered by NAI's Extended Remarketing Rights.

              (F) Payment Only to BNPLC. All amounts payable under this
Agreement by NAI and, if applicable, by an Applicable Purchaser must be paid
directly to BNPLC, and no payment to any other party shall be effective for the
purposes of this Agreement. In addition to the payments required under
subparagraph 1.(A), on the Designated Sale Date NAI must pay all amounts then
due to BNPLC under the Land Lease or other Operative Documents.

              (G) Remedies Under the Other Operative Documents. No repossession
of or re-entering upon the Property or exercise of any other remedies available
to BNPLC under the Land Lease or other Operative Documents shall terminate NAI's
rights or obligations hereunder, all of which shall survive BNPLC's exercise of
remedies under the other Operative Documents. NAI acknowledges that the
consideration for this Agreement is separate and independent of the
consideration for the Land Lease and the Closing Certificate, and NAI's
obligations hereunder shall not be affected or impaired by any event or
circumstance that would excuse NAI from performance of its obligations under
such other Operative Documents.

              (H) Occupancy by NAI Prior to Closing of a Sale. Prior to the
closing of any sale of the Property to NAI or an Applicable Purchaser hereunder,
NAI's occupancy of the Land and its use of the Property shall continue to be
subject to the terms and conditions of the Land Lease, including the terms
setting forth NAI's obligation to pay rent, prior to any termination or
expiration of the Land Lease pursuant to its express terms and conditions.

       5. SECURITY FOR NAI'S OBLIGATIONS; RETURN OF FUNDS. NAI's obligations
under this Agreement are secured by the Pledge Agreement, reference to which is
hereby made for a description of the Collateral covered thereby and the rights
and remedies provided to BNPLC thereby. Although the collateral agent appointed
for BNPLC as provided in the Pledge Agreement shall be entitled to hold all
Collateral as security for the full and faithful performance by NAI of NAI's
covenants and obligations under this Agreement, the Collateral shall not be
considered an advance payment of the Break Even Price or any Supplemental
Payment or a measure of BNPLC's damages should NAI breach this Agreement. If NAI
does breach this Agreement and fails to cure the same within any time specified
herein for the cure, BNPLC may, from time to time, without prejudice to any
other remedy and without notice to NAI, require the collateral agent to
immediately apply the proceeds of any disposition of the Collateral (and any
cash included in the Collateral) to amounts then due hereunder from NAI. If by a
Permitted Transfer BNPLC conveys its interest in the Property before the
Designated Sale Date, BNPLC may also assign BNPLC's interest in the Collateral
to the transferee. BNPLC shall be entitled to return any Collateral not sold or
used to satisfy the obligations secured by the Pledge Agreement directly to NAI
notwithstanding any prior actual or attempted conveyance or assignment by NAI,
voluntary or otherwise, of any right to receive the same; neither BNPLC nor the
collateral agent named in the Pledge Agreement shall be responsible for the
proper distribution or application by NAI of any such Collateral returned to
NAI; and any such return of Collateral to NAI shall discharge any obligation of
BNPLC to deliver such Collateral to all Persons claiming an interest in the
Collateral. Further, BNPLC shall be entitled to deliver any Escrowed Proceeds it
holds on the Designated Sale Date directly to NAI or to any Applicable Purchaser
purchasing BNPLC's interest in the Property and the Escrowed Proceeds pursuant
to



                                       10
<PAGE>   14

this Agreement notwithstanding any prior actual or attempted conveyance or
assignment by NAI, voluntary or otherwise, of any right to receive the same;
BNPLC shall not be responsible for the proper distribution or application by NAI
or any Applicable Purchaser of any such Escrowed Proceeds paid over to NAI or
the Applicable Purchaser; and any such payment of Escrowed Proceeds to NAI or an
Applicable Purchaser shall discharge any obligation of BNPLC to deliver the same
to all Persons claiming an interest therein.

       6. CERTAIN REMEDIES CUMULATIVE. No right or remedy herein conferred upon
or reserved to BNPLC is intended to be exclusive of any other right or remedy
BNPLC has with respect to the Property, and each and every right and remedy
shall be cumulative and in addition to any other right or remedy given hereunder
or now or hereafter existing at law or in equity or by statute. In addition to
other remedies available under this Agreement, either party shall be entitled,
to the extent permitted by applicable law, to a decree compelling performance of
any of the other party's agreements hereunder.

       7. ATTORNEYS' FEES AND LEGAL EXPENSES. If either party to this Agreement
commences any legal action or other proceeding to enforce any of the terms of
this Agreement, or because of any breach by the other party or dispute
hereunder, the party prevailing in such action or proceeding shall be entitled
to recover from the other party all Attorneys' Fees incurred in connection
therewith, whether or not such controversy, claim or dispute is prosecuted to a
final judgment. Any such Attorneys' Fees incurred by either party in enforcing a
judgment in its favor under this Agreement shall be recoverable separately from
such judgment, and the obligation for such Attorneys' Fees is intended to be
severable from other provisions of this Agreement and not to be merged into any
such judgment.

       8. ESTOPPEL CERTIFICATE. Upon request by BNPLC, NAI shall execute,
acknowledge and deliver a written statement certifying that this Agreement is
unmodified and in full effect (or, if there have been modifications, that this
Agreement is in full effect as modified, and setting forth such modification)
and either stating that no default exists hereunder or specifying each such
default of which NAI has knowledge. Any such statement may be relied upon by any
Participant or prospective purchaser or assignee of BNPLC with respect to the
Property.

       9. SUCCESSORS AND ASSIGNS. The terms, provisions, covenants and
conditions hereof shall be binding upon NAI and BNPLC and their respective
permitted successors and assigns and shall inure to the benefit of NAI and BNPLC
and all permitted transferees, mortgagees, successors and assignees of NAI and
BNPLC with respect to the Property; provided, that (A) the rights of BNPLC
hereunder shall not pass to NAI or any Applicable Purchaser or any subsequent
owner claiming through NAI or an Applicable Purchaser, (B) BNPLC shall not
assign this Agreement or any rights hereunder except pursuant to a Permitted
Transfer, and (C) NAI shall not assign this Agreement or any rights hereunder
without the prior written consent of BNPLC.

                                    EXHIBIT B

              REQUIREMENTS RE: FORM OF GRANT DEED AND GROUND LEASE

The form of deed to be used to convey BNPLC's interest in the Land to NAI or an
Applicable Purchaser will depend upon whether BNPLC's interest in the
Improvements has been or is being conveyed at the same time to the same party.

If BNPLC's interests in both the Land and the Improvements are to be conveyed to
NAI or an Applicable Purchaser at the same time, because a sale under this
Purchase Agreement and a sale under the Other Purchase Agreement (covering the
Improvements) are being consummated at the same time and to the same party, then
the one deed in form attached as Exhibit B-1 will be used to convey both.

If, however, a sale of BNPLC's interest in the Improvements pursuant to the
Other Purchase Agreement has not been consummated before, and is not being
consummated contemporaneously with the sale of BNPLC's interest in the Land
under this Agreement, then BNPLC's interest in the Land will be conveyed by a
deed in the from attached as Exhibit B-2, and BNPLC and the grantee under such
deed shall, as a condition to BNPLC's obligation to deliver the deed, execute
and deliver a Ground Lease covering the Land in the form attached hereto as
Exhibit B-3.

Finally, BNPLC's interest in the Land will be conveyed by a deed in the from
attached as Exhibit B-4 if BNPLC's interest in the Improvements has been sold
pursuant to the Other Purchase Agreement before a sale of BNPLC's interest in
the Land under this Agreement, or if BNPLC's interest in the Improvements is
being sold contemporaneously with a sale of BNPLC's interest in the Land, but
the purchaser of the Improvements is not the same as the purchaser of the Land.

                                  GROUND LEASE

       This GROUND LEASE (this "GROUND LEASE"), by and between BNP LEASING
CORPORATION, a Delaware corporation ("BNPLC"), whose address is 12201 Merit
Drive, Suite 860,Dallas, Texas 75251, and [NAI or the Applicable Purchaser], a
___________ ("LESSOR"), whose address is ____________________. as of
____________, ____ (the "GL EFFECTIVE DATE").

                                    RECITALS

       This Ground Lease is being executed pursuant to a Purchase Agreement
(Phase IV - Land) dated as of October ___, 2000 (the "PURCHASE AGREEMENT"),
between BNP Leasing Corporation and Network Appliance, Inc., covering the land
described in Annex 1 attached hereto (the "LAND"). Incorporated by reference
into the Purchase Agreement is a Common Definitions and Provisions Agreement
(Phase IV - Land) dated as of the effective date of the Purchase Agreement (the
"CDPA"), between BNP Leasing Corporation and Network Appliance, Inc. The CDPA is
hereby incorporated into and made a part of this Ground Lease for all purposes.
Capitalized terms defined in the CDPA and used but not otherwise defined herein
are intended in this Ground Lease to have the respective meanings ascribed to
them in the CDPA. The provisions in Article II of the CDPA are intended to apply
to this Ground Lease as if set forth herein and as if this Ground Lease were one
of the "Operative Documents" as defined therein.

       Lessor and BNPLC have reached agreement as to the terms and conditions
upon which Lessor is willing to lease the Land described in Annex 1 to BNPLC for
a term of approximately just less that 35 years, and by this Ground Lease Lessor
and BNPLC desire to evidence such agreement.

                                GRANTING CLAUSES

       NOW, THEREFORE, in consideration of the rent to be paid and the covenants
and agreements to be performed by BNPLC, as hereinafter set forth, Lessor does
hereby LEASE, DEMISE and LET unto BNPLC for the term hereinafter set forth the
Land, together with:

              1.     all easements and rights-of-way now owned or hereafter
                     acquired by Lessor for use in connection with the Land or
                     as a means of access thereto; and

              2.     all right, title and interest of Lessor, now owned or
                     hereafter acquired, in and to (A) any land lying within the
                     right-of-way of any street, open or proposed, adjoining the
                     Land, (B) any and all sidewalks and alleys adjacent to the
                     Land and (C) any strips and gores between the Land and any
                     abutting land not owned by Lessor.

The Land and all of the property described in the preceding clauses (1) and (2)
are hereinafter referred to collectively as the "REAL PROPERTY".



                              EXHIBIT B-3 - PAGE 1
<PAGE>   42

       To the extent, but only to the extent, that assignable rights or
interests in, to or under the following have been or will be acquired by Lessor
as the owner of any interest in the Real Property, Lessor also hereby grants and
assigns to BNPLC for the term of this Ground Lease (and thereafter, if BNPLC
purchases the Real Property from Lessor pursuant to the Repurchase Option
described in Paragraph 12) the right to use and enjoy (and, in the case of
contract rights, to enforce) such rights or interests of Lessor:

                     (a)    the Permitted Encumbrances; and

                     (b) any general intangibles, permits, licenses, franchises,
       certificates, and other rights and privileges related to the Real
       Property that BNPLC (rather than Lessor) would have acquired if BNPLC had
       itself acquired the fee estate in the Real Property (excluding, however,
       any rights and privileges of Lessor under this Ground Lease, any rights
       or privileges of Lessor under the Purchase Agreement or other Operative
       Documents, and [without limiting Lessor's obligations under subparagraphs
       4.(B), 6.(B) or 6.(C)] any rights and privileges of Lessor under the
       Development Documents described in Annex 3).

Such rights and interests of Lessor, whether now existing or hereafter arising,
are hereinafter collectively called the "GL PERSONAL PROPERTY". The Real
Property and the GL Personal Property are hereinafter sometimes collectively
called the "GL PROPERTY."

       Provided, however, the leasehold estate conveyed hereby and BNPLC's
rights hereunder are expressly made subject and subordinate to the Permitted
Encumbrances, including those listed on Annex 2. FURTHER, IF AND SO LONG AS THE
OTHER LEASE AGREEMENT AND THE OTHER PURCHASE AGREEMENT (BOTH AS DEFINED IN THE
CDPA) REMAIN IN FORCE, THE RIGHTS AND OBLIGATIONS OF LESSOR AND BNPLC HEREUNDER
SHALL BE SUBJECT TO ANY CONTRARY PROVISIONS THEREIN. ACCORDINGLY, BNPLC'S RIGHTS
UNDER PARAGRAPH 7 BELOW SHALL BE SUBJECT TO THE PROVISIONS GOVERNING INSURANCE
AND CONDEMNATION IN THE OTHER LEASE AGREEMENT, IF AND SO LONG AS THE OTHER LEASE
AGREEMENT REMAINS IN FORCE.

                          GENERAL TERMS AND CONDITIONS

       The GL Property is leased by Lessor to BNPLC and is accepted and is to be
used and possessed by BNPLC upon and subject to the following terms and
conditions:

       1. GROUND LEASE TERM AND EARLY TERMINATION BY BNPLC. The term of this
Ground Lease (the "GROUND LEASE TERM") shall commence on and include the GL
Effective Date and end on last Business Day prior to the thirty-fifth
anniversary of the GL Effective Date. However, subject to the prior approval of
any Leasehold Mortgagee, BNPLC shall have the right to terminate this Ground
Lease by giving a notice to Lessor stating that BNPLC unequivocally elects to
terminate effective as of a date specified in such notice, which may be any date
more than thirty days after the notice and after the expiration or termination
of the Lease pursuant to its terms.



                              EXHIBIT B-3 - PAGE 2
<PAGE>   43

       2. NO OTHER GROUND LEASE TERMINATION. Except as expressly provided
herein, this Ground Lease shall not terminate, nor shall Lessor have any right
to terminate this Ground Lease, nor shall the obligations of Lessor under this
Ground Lease be excused, for any reason whatsoever, including any of the
following: (i) any damage to or the destruction of all or any part of the GL
Property from whatever cause, (ii) the taking of the GL Property or any portion
thereof by eminent domain or otherwise for any reason, (iii) any default on the
part of BNPLC under this Ground Lease or under any other agreement to which
Lessor and BNPLC are parties, or (iv) any other cause whether similar or
dissimilar to the foregoing, any existing or future law to the contrary
notwithstanding. It is the intention of the parties hereto that the obligations
of Lessor hereunder shall be separate and independent of the covenants and
agreements of BNPLC. However, nothing in this Paragraph shall be construed as a
waiver by Lessor of any right Lessor may have at law or in equity to recover
monetary damages for any default under this Ground Lease by BNPLC.

       3. GROUND LEASE RENT. On each anniversary of the GL Effective Date, BNPLC
shall make a payment to Lessor of rent for the then preceding year ("GROUND
LEASE RENT"), in currency that at the time of payment is legal tender for public
and private debts in the United States of America. Each such payment of Ground
Lease Rent shall equal the Fair Rental Value, determined as provided in Annex 4.

       4. USE OF GL PROPERTY.

              (A) Permitted Uses and Construction of Improvements. Subject to
the Permitted Encumbrances and the terms hereof, BNPLC may use and occupy the GL
Property for any purpose permitted by Applicable Laws and may construct,
maintain and use any Improvements on the Land which are permitted by Applicable
Laws.

              (B) Cooperation by Lessor and its Affiliates.

              (1) After the expiration or any earlier termination of the Lease,
       if a use of the GL Property by BNPLC or any new Improvements or any
       removal or modification of Improvements proposed by BNPLC would violate
       any Permitted Encumbrance, Development Document or Applicable Law unless
       Lessor or any of its Affiliates, as an owner of adjacent property or
       otherwise, gave its consent or approval thereto or agreed to join in a
       modification of a Permitted Encumbrance or Development Document, then
       Lessor shall give and cause its Affiliates to give such consent or
       approval or join in such modification.

              (2) To the extent, if any, that any Permitted Encumbrance,
       Development Document or Applicable Law requires the consent or approval
       of Lessor or any of its Affiliates or of the City of South San Francisco
       or any other Person to an assignment of this Ground Lease or a transfer
       of any interest in the GL Property by BNPLC or its successors or assigns,
       Lessor will without charge give and cause its Affiliates to give such
       consent or approval and will cooperate in any way reasonably requested by
       BNPLC to assist BNPLC to obtain such consent or approval from the City or
       any other Person; provided, however, the assignment or transfer is not
       then prohibited by the Lease.



                              EXHIBIT B-3 - PAGE 3
<PAGE>   44

              (3) Lessor's obligations under this subparagraph 4.(B) shall be
       binding upon any successor or assign of Lessor with respect to the Land
       and other properties encumbered by the Permitted Encumbrances or subject
       to the Development Documents, and such obligations shall survive any sale
       of Lessor's interest in the GL Property to BNPLC because of BNPLC's
       exercise of the Repurchase Option (as defined in Paragraph 12).

              (C) Title to Improvements. Any and all Improvements of whatever
nature at any time constructed, placed or maintained upon any part of the Land
shall be and remain the property of BNPLC and BNPLC's sublessee's, assignees,
licensees and concessionaires, as their interests may appear; provided, any such
Improvements which remain on the Land when this Ground Lease expires or is
terminated shall become and thereupon be the property of Lessor, free and clear
of any Liens Removable by BNPLC. It is the intention of Lessor and BNPLC that
severance of fee title to the Land and the Improvements shall not change the
character of the Improvements as real property. BNPLC may at any time after
Lessor ceases to have possession of the GL Property as tenant under the Lease
and prior to the expiration or termination of this Ground Lease remove all or
any Improvements from the Land without the consent of Lessor and without any
obligation to Lessor or its Affiliates to provide compensation or to construct
other Improvements on or about the Land.

       5. ASSIGNMENT AND SUBLETTING; PASS THROUGH OF BNPLC'S LIABILITY INSURANCE
AND INDEMNITY RIGHTS. BNPLC may sublet or assign this Ground Lease without the
consent of Lessor or any of its Affiliates, subject only to limitations set
forth in the Lease for the benefit of Lessor so long as those limitations remain
in force.

       To the extent that BNPLC may from time to time after the expiration or
earlier termination of the Other Lease Agreement require any subtenant to agree
to maintain liability insurance against claims of third parties and agree to
make BNPLC an additional or named insured under such insurance, BNPLC shall also
require the subtenant to agree to make Lessor an additional or named insured.
However, BNPLC shall have no liability to Lessor for a breach by the subtenant
of any such agreements, and to the extent that BNPLC's rights as an additional
or named insured are subject to exceptions or limitations concerning BNPLC's own
acts or omissions or the acts or omissions of anyone other than the subtenant,
so too may Lessor's rights as an additional or named insured be subject to
exceptions or limitations concerning Lessor's own acts or omissions or the acts
or omissions of anyone other than the subtenant.

       To the extent that BNPLC may itself from time to time after the
expiration or earlier termination of the Other Lease Agreement maintain
liability insurance against claims of third parties which may arise because of
any occurrence on or alleged to have occurred on or about the GL Property, BNPLC
shall cause Lessor to be an additional or named insured under such insurance,
provided Lessor pays or reimburses BNPLC for any additional insurance premium
required to have Lessor made an insured.

       To the extent that BNPLC may from time to time after the expiration or
earlier termination of the Other Lease Agreement require any subtenant to agree
to indemnify BNPLC against Environmental Losses or other Losses concerning the
GL Property, BNPLC shall also require the subtenant to agree to indemnify
Lessor. However, BNPLC shall have no liability to



                              EXHIBIT B-3 - PAGE 4
<PAGE>   45

Lessor for a breach by the subtenant of any such agreement, and to the extent
that BNPLC's rights as an indemnitee of the subtenant are subject to exceptions
or limitations concerning BNPLC's own acts or omissions or the acts or omissions
of anyone other than the subtenant, so too may Lessor's rights as an indemnitee
be subject to exceptions or limitations concerning Lessor's own acts or
omissions or the acts or omissions of anyone other than the subtenant.

       6. REPRESENTATIONS, WARRANTIES AND COVENANTS OF LESSOR CONCERNING THE
PROPERTY. Lessor represents, warrants and covenants as follows:

              (A) Title to the Property. This Ground Lease shall vest in BNPLC
good and marketable title to a leasehold estate in the Land, subject only to the
terms and conditions hereof, the Permitted Encumbrances, the Development
Documents and any Liens Removable by BNPLC. Lessor shall not, without the prior
consent of BNPLC, create, place or authorize, or through any act or failure to
act, acquiesce in the placing of, any deed of trust, mortgage or other Lien,
whether statutory, constitutional or contractual against or covering the GL
Property or any part thereof (other than Permitted Encumbrances and Liens
Removable by BNPLC), regardless of whether the same are expressly or otherwise
subordinate to the Operative Documents or BNPLC's interest in the Property.

              (B) Modification of Permitted Encumbrances and Development
Documents. Without the prior consent of BNPLC, Lessor shall not enter into,
initiate, approve or consent to any modification of any Permitted Encumbrance or
Development Document that would create or expand or purport to create or expand
obligations or restrictions which would encumber the GL Property or any
improvements constructed thereon.

              (C) Performance and Preservation of the Development Documents and
Permitted Encumbrances for the Benefit of BNPLC. Not only during the term of the
Other Lease Agreement, but thereafter throughout the term of this Ground Lease,
Lessor shall comply with and perform the obligations imposed by the Permitted
Encumbrances and the Development Documents upon Lessor or upon any owner of the
Land, and shall do whatever is required to preserve the rights and benefits
conferred or intended to be conferred by the Permitted Encumbrances and the
Development Documents, as necessary to facilitate the construction of the
Construction Project on the Land as contemplated in the Other Lease Agreement
and the use of the Improvements included in the Construction Project by BNPLC
and its successors, assigns and subtenants under this Ground Lease after the
expiration or any earlier termination of the Other Lease Agreement. Further, if
Lessor or any Affiliate of Lessor now or hereafter owns, acquires or leases land
(other than the Land) that is the subject of a Permitted Encumbrance or
Development Document, then Lessor shall, and shall cause its Affiliate to,
assume liability for and indemnify BNPLC and other Interested Parties and defend
and hold them harmless from and against all Losses (including Losses caused by
any decline in the value of the Property or of the Improvements) that they would
not have incurred or suffered but for (i) a termination of such Permitted
Encumbrance or Development Document, to which Lessor or its Affiliate agreed, or
which resulted from a breach thereof by Lessor or its Affiliate, or (ii) a
refusal of Lessor or its Affiliate to agree to any waiver or modification
requested by BNPLC of restrictions upon the Property or the transfer thereof
imposed by such Permitted Encumbrance or Development Document, or (iii) anything
done, authorized or suffered by Lessor or its Affiliate in violation of such
Permitted Encumbrance or Development Document. Lessor's obligations under this



                              EXHIBIT B-3 - PAGE 5
<PAGE>   46

subparagraph 6.(C) shall be binding upon any successor or assign of Lessor or
its Affiliates with respect to their interest in properties subject to the
Development Documents and Permitted Encumbrances.

       7. INSURANCE AND CONDEMNATION.

              (A) Entitlement to Insurance and Condemnation Proceeds. All
insurance and condemnation proceeds payable with respect to any damage to or
taking of the GL Property shall be payable to and become the property of BNPLC;
provided, however, Lessor shall be entitled to receive condemnation proceeds
awarded for the value of Lessor's remainder interest in the Land exclusive of
the Improvements. BNPLC is authorized to take all action necessary on behalf of
both BNPLC and Lessor (as lessor under this Ground Lease) to collect insurance
and condemnation proceeds.

              (B) Collection of Insurance Proceeds. In the event any of the GL
Property is destroyed or damaged by fire, explosion, windstorm, hail or by any
other casualty against which insurance shall have been required hereunder, (i)
BNPLC may make proof of loss, (ii) each insurance company concerned is hereby
authorized and directed to make payment for such loss directly to BNPLC for
application as required by subparagraph 7.(A), and (iii) BNPLC's consent must be
obtained for any settlement, adjustment or compromise of any claims for loss,
damage or destruction under any policy or policies of insurance.

              (C) Collection of Condemnation Proceeds. All proceeds of
condemnation awards or proceeds of sale in lieu of condemnation with respect to
the GL Property and all judgments, decrees and awards for injury or damage to
the GL Property shall be paid to BNPLC and applied as provided in subparagraph
7.(A) above. BNPLC is hereby authorized, in the name of Lessor, to execute and
deliver valid acquittances for, and to appeal from, any such judgment, decree or
award concerning condemnation of any of the GL Property. BNPLC shall not be, in
any event or circumstances, liable or responsible for failure to collect, or to
exercise diligence in the collection of, any such proceeds, judgments, decrees
or awards.

       8. LEASEHOLD MORTGAGES.

              (A) By Leasehold Mortgage BNPLC may encumber BNPLC's leasehold
estate in the GL Property created by this Ground Lease, as well as BNPLC's
rights and interests in buildings, fixtures, equipment and Improvements situated
on the Land and rents, issues, profits, revenues and other income to be derived
by BNPLC therefrom.

              (B) Any Leasehold Mortgagee or other party, including any
corporation formed by a Leasehold Mortgagee, may become the legal owner of the
leasehold estate created by this Ground Lease, and of the Improvements,
equipment, fixtures and other property assigned as additional security pursuant
to a Leasehold Mortgage, by foreclosure of a Leasehold Mortgage or as a result
of the assignment or conveyance in lieu of foreclosure. Further, any such
Leasehold Mortgagee or other party may itself, after becoming the legal owner
and holder of the leasehold estate created by this Ground Lease, or of any
Improvements, equipment, fixtures and other property assigned as additional
security pursuant to a Leasehold Mortgage, convey or pledge the same without the
consent of Lessor.



                              EXHIBIT B-3 - PAGE 6
<PAGE>   47

              (C) Lessor shall serve notice of any default by BNPLC hereunder
upon any Leasehold Mortgagee. No notice of a default by BNPLC shall be deemed
effective until it is so served. Any Leasehold Mortgagee shall have the right to
correct or cure any such default within the same period of time after receipt of
such notice as is given to BNPLC under this Ground Lease to correct or cure
defaults, plus an additional period of thirty days thereafter. Lessor will
accept performance by any Leasehold Mortgagee of any covenant, condition or
agreement on BNPLC's part to be performed hereunder with the same force and
effect as though performed by BNPLC.

              (D) If this Ground Lease should terminate by reason of a
disaffirmance or rejection of this Ground Lease by BNPLC or any receiver,
liquidator or trustee for the property of BNPLC, or by any governmental
authority which had taken possession of the business or property of BNPLC by
reason of the insolvency or alleged insolvency of BNPLC, then:

              (1) Lessor shall give notice thereof to each Leasehold Mortgagee;
       and upon request of any Leasehold Mortgagee made within sixty days after
       Lessor has given such notice, Lessor shall enter into a new ground lease
       of the GL Property with such Leasehold Mortgagee for the remainder of the
       Ground Lease Term, at the same Ground Lease Rent and on the same terms
       and conditions as contained in this Ground Lease.

              (2) The estate of the Leasehold Mortgagee, as lessee under the new
       lease, shall have priority equal to the estate of BNPLC hereunder. That
       is, there shall be no charge, lien or burden upon the GL Property prior
       to or superior to the estate granted by such new lease which was not
       prior to or superior to the estate of BNPLC under this Ground Lease as of
       the date immediately preceding the termination of this Ground Lease.

              (3) Notwithstanding the foregoing, if Lessor shall receive
       requests to enter into a new ground lease from more than one Leasehold
       Mortgagee, Lessor shall be required to enter into only one new ground
       lease, and the new ground lease shall be to the requesting Leasehold
       Mortgagee who holds the highest priority lien or interest in BNPLC's
       leasehold estate in the Land. If the liens or security interests of two
       or more such requesting Leasehold Mortgagees which shared the highest
       priority just prior to the termination of this Ground Lease, the new
       ground lease shall name all such Leasehold Mortgagees as co-tenants
       thereunder.

              (E) If BNPLC has agreed with any Leasehold Mortgagee that such
Leasehold Mortgagee's consent will be required to any modification or early
termination of this Ground Lease by BNPLC, and if Lessor has been notified of
such agreement, such consent will be required.

              (F) No Leasehold Mortgagee will assume any liability under this
Ground Lease either by virtue of its Leasehold Mortgage or by any subsequent
receipt or collection of rents or profits generated from the GL Property, unless
and until the Leasehold Mortgagee acquires BNPLC's leasehold estate in the GL
Property at foreclosure or by deed in lieu of foreclosure.



                              EXHIBIT B-3 - PAGE 7
<PAGE>   48

              (G) Although the foregoing provisions concerning Leasehold
Mortgages and Leasehold Mortgagees will be self operative, Lessor agrees to
include, in addition to the items specified in Paragraph 11, confirmation of the
foregoing in any statement provided to a Leasehold Mortgagee or prospective
Leasehold Mortgagee pursuant to Paragraph 11.

       9. EVENTS OF DEFAULT.

              (A) Definition of Ground Lease Default. Each of the following
events shall be deemed to be a "Ground Lease Default" by BNPLC under this Ground
Lease:

              (1) BNPLC shall fail to pay when due any installment of Ground
       Lease Rent due hereunder and such failure shall continue for sixty days
       after BNPLC receives notice thereof.

              (2) BNPLC shall fail to comply with any term, provision or
       covenant of this Ground Lease (other than as described in the other
       clauses of this subparagraph 9.(A)), and shall not cure such failure
       prior to the earlier of (A) ninety days after notice thereof is sent to
       BNPLC, or (B) the date any writ or order is issued for the levy or sale
       of any property owned by Lessor or its Affiliates (including the GL
       Property) because of such failure or any criminal action is instituted
       against BNPLC or any of its directors, officers or employees because of
       such failure; provided, however, that so long as no such writ or order is
       issued and no such criminal actions is instituted, if such failure is
       susceptible of cure but cannot with reasonable diligence be cured within
       such ninety day period, and if BNPLC shall promptly have commenced to
       cure the same and shall thereafter prosecute the curing thereof with
       reasonable diligence, the period within which such failure may be cured
       shall be extended for such further period as shall be necessary for the
       curing thereof with reasonable diligence.

              (B) Remedy. Upon the occurrence of a Ground Lease Default which is
not cured within any applicable period expressly permitted by subparagraph
9.(A), Lessor's sole and exclusive remedies shall be to sue BNPLC for the
collection of any amount due under this Ground Lease, to sue for the specific
enforcement of BNPLC's obligations hereunder, or to enjoin the continuation of
the Ground Lease Default; provided, however, no limitation of Lessor's remedies
contained herein will prevent Lessor from recovering any reasonable costs Lessor
may incur to mitigate its damages by curing a Ground Lease Default that BNPLC
has failed to cure itself (so long as the cure by Lessor is pursued in a lawful
manner and the costs Lessor seeks to recover do not exceed the actual damages to
be mitigated). Lessor may not terminate this Ground Lease or BNPLC's right to
possession under this Ground Lease. Any judgment which Lessor may obtain against
BNPLC for amounts due under this Ground Lease may be collected only through
resort of a judgement lien against BNPLC's interest in the GL Property and any
Improvements. BNPLC shall have no personal liability for the payment amounts due
under this or for the performance of any obligations of BNPLC under this Ground
Lease.

       10. QUIET ENJOYMENT. Neither Lessor nor any third party lawfully claiming
any right or interest in the GL Property shall during the Ground Lease Term
disturb BNPLC's peaceable and quiet enjoyment of the GL Property; however, such
enjoyment shall be subject to



                              EXHIBIT B-3 - PAGE 8
<PAGE>   49

the terms, provisions, covenants, agreements and conditions of this Ground Lease
and the Permitted Encumbrances, to which this Ground Lease is subject and
subordinate as herein above set forth.

       11. ESTOPPEL CERTIFICATE. Lessor shall from time to time, within ten days
after receipt of request by BNPLC, deliver a statement in writing certifying:

              (A) that this Ground Lease is unmodified and in full force and
effect (or if modified that this Ground Lease as so modified is in full force
and effect);

              (B) that to the knowledge of Lessor BNPLC has not previously
assigned or hypothecated its rights or interests under this Ground Lease, except
as is described in such statement with as much specificity as Lessor is able to
provide;

              (C) the term of this Ground Lease and the Ground Lease Rent then
in effect and any additional charges;

              (D) that BNPLC is not in default under any provision of this
Ground Lease (or if in default, the nature thereof in detail) and a statement as
to any outstanding obligations on the part of Lessor or BNPLC; and

              (E) such other matters as are reasonably requested by BNPLC.

Lessor's failure to deliver such statement within such time shall be conclusive
upon BNPLC (i) that this Ground Lease is in full force and effect, without
modification except as may be represented by BNPLC, (ii) that there are no
uncured defaults in BNPLC's performance hereunder.

       12. OPTION TO REPURCHASE. Subject to the terms and conditions set forth
in Annex 5, BNPLC (and any assignee of BNPLC's entire interest in the GL
Property, but not any subtenant or assignee of a lesser interest) shall have the
option (the "REPURCHASE OPTION") to purchase Lessor's interest in the GL
Property. To secure BNPLC's right to recover any damages caused by a breach of
the Repurchase Option or other provisions of this Ground Lease by Lessor,
including any such breach caused by a rejection or termination of this Ground
Lease in any bankruptcy or insolvency proceeding instituted by or against
Lessor, as debtor, Lessor does hereby grant to BNPLC a lien and security
interest against the Land and against all rights, title and interests of Lessor
from time to time in and to the GL Property.

                       DETERMINATION OF FAIR RENTAL VALUE

       Each annual payment of Ground Lease Rent will equal the Fair Rental
Value, computed as of the most recent Rental Determination Date when such
payment becomes due. As used in this Annex:

              "FAIR RENTAL VALUE" means (and all appraisers and other persons
       involved in the determination of the Fair Rental Value will be so
       advised) the annual rent, as determined in accordance with this Annex,
       that would be agreed upon between a willing tenant, under no compulsion
       to lease, and a willing landlord, under no compulsion to lease, for
       unimproved land comparable in size and location to the Land, exclusive of
       any Improvements but assuming that there is no higher and better use for
       such land than as a site for improvements of comparable size and utility
       to the Improvements, at the time a determination is required under
       hereunder and taking into consideration the condition of the Land, the
       encumbrances affecting the title to the Land and all applicable zoning,
       land use approvals and other governmental permits relating to the Land at
       the time of such determination; and

              "RENTAL DETERMINATION DATE" means the GL Effective Date and each
       fifth anniversary of the GL Effective Date.

       If Lessor and BNPLC have not agreed upon Fair Rental Value as of any
Rental Determination Date within one hundred eighty days after the such date,
then Fair Rental Value will be determined as follows:

              (a) Lessor and BNPLC shall each appoint a real estate appraiser
       who is familiar with rental values for properties in the vicinity of the
       Land and who has not previously acted for either party. Each party will
       make the appointment no later than ten days after receipt of notice from
       the other party that the appraisal process described in this Annex has
       been invoked. The agreement of the two appraisers as to Fair Rental Value
       will be binding upon Lessor and BNPLC. If the two appraisers cannot agree
       upon the Fair Rental Value within ten days following their appointment,
       they shall within another ten days agree upon a third real estate
       appraiser. Immediately thereafter, each of the first two appraisers will
       submit his best estimate of the appropriate Fair Rental Value (together
       with a written report supporting such estimate) to the third appraiser
       and the third appraiser will choose between the two estimates. The
       estimate of Fair Rental Value chosen by the third appraiser as the
       closest to the prevailing annual fair rental value will be binding upon
       Lessor and BNPLC. Notification in writing of this estimate shall be made
       to Lessor and BNPLC within fifteen days following the selection of the
       third appraiser.

              (b) If appraisers must be selected under the procedure set out
       above and either BNPLC or Lessor fails to appoint an appraiser or fails
       to notify the other party of such appointment within fifteen days after
       receipt of notice that the prescribed time for appointing the appraisers
       has passed, then the other party's appraiser will determine the



                             EXHIBIT B-3 - PAGE 18
<PAGE>   59

       Fair Rental Value. All appraisers selected for the appraisal process set
       out in this Annex will be disinterested, reputable, qualified real estate
       appraisers with the designation of MAI or equivalent and with at least 5
       years experience in appraising properties comparable to the Land.

              (c) If a third appraiser must be chosen under the procedure set
       out above, he or she will be chosen on the basis of objectivity and
       competence, not on the basis of his relationship with the other
       appraisers or the parties to this Ground Lease, and the first two
       appraisers will be so advised. Although the first two appraisers will be
       instructed to attempt in good faith to agree upon the third appraiser, if
       for any reason they cannot agree within the prescribed time, either
       Lessor and BNPLC may require the first two appraisers to immediately
       submit its top choice for the third appraiser to the then highest ranking
       officer of the California Bar Association who will agree to help and who
       has no attorney/client or other significant relationship to either Lessor
       or BNPLC. Such officer will have complete discretion to select the most
       objective and competent third appraiser from between the choices of each
       of the first two appraisers, and will do so within twenty days after such
       choices are submitted to him.

              (d) Either Lessor or BNPLC may notify the appraiser selected by
       the other party to demand the submission of an estimate of Fair Rental
       Value or a choice of a third appraiser as required under the procedure
       described above; and if the submission of such an estimate or choice is
       required but the other party's appraiser fails to comply with the demand
       within fifteen days after receipt of such notice, then the Fair Rental
       Value or choice of the third appraiser, as the case may be, selected by
       the other appraiser (i.e., the notifying party's appraiser) will be
       binding upon Lessor and BNPLC.

              (e) Lessor and BNPLC shall each bear the expense of the appraiser
       appointed by it, and the expense of the third appraiser and of any
       officer of the California Bar Association who participates in the
       appraisal process described above will be shared equally by Lessor and
       BNPLC.

                                     ANNEX 5

                                REPURCHASE OPTION

       Subject to the terms of this Annex, BNPLC shall have an option (the
"OPTION") to buy Lessor's fee interest in the GL Property at any time during the
term of this Ground Lease for a purchase price (the "OPTION PRICE") to Lessor
equal to the fair market value of the GL Property, determined as described in
the next paragraph.

       For the purposes of this Annex, "fair market value" of the GL Property
means (and all appraisers and other persons involved in the determination of the
Option Price will be so advised) the price that would be agreed upon between a
willing buyer, under no compulsion to buy, and a willing seller, under no
compulsion to sell, for the Land, exclusive of any Improvements as if the Land
were unimproved, but assuming that there is no higher and better use for the
Land than as a site for the construction of improvements of comparable size and
utility to the Improvements, at the time of BNPLC's exercise of the Option and
taking into consideration the encumbrances affecting the title to the Land and
all applicable zoning, land use approvals and other governmental permits
relating to the Land at the time of the exercise of the Option.

       If BNPLC exercises the Option, which BNPLC may do by notifying Lessor
that BNPLC has elected to buy Lessor's interest in the GL Property as provided
herein, then:

              (a) To the extent, if any, required as a condition imposed by law
       to the conveyance of the fee interest in the GL Property to BNPLC, Lessor
       shall promptly at its expense do whatever is necessary to obtain
       approvals of a new Parcel Map or lot line adjustments.

              (b) Upon BNPLC's tender of the Option Price to Lessor, Lessor will
       convey to BNPLC by general warranty deed and assignment, subject only to
       the Permitted Encumbrances, good and marketable title to the fee estate
       in the Land, to Lessor's interest in all other GL Property and, to the
       extent still in force, to Lessor's Extended Remarketing Rights under the
       Purchase Agreement.

              (c) BNPLC's obligation to close the purchase shall be subject to
       the following terms and conditions, all of which are for the benefit of
       BNPLC: (1) BNPLC shall have been furnished with evidence satisfactory to
       BNPLC that Lessor can convey title as required by the preceding
       subparagraph; (2) nothing shall have occurred or been discovered after
       BNPLC exercised the Option that could significantly and adversely affect
       title to the GL Property or BNPLC's use thereof, (3) all of the
       representations of Lessor in this Ground Lease shall continue to be true
       as if made effective on the date of the closing and, with respect to any
       such representations which may be limited to the knowledge of Lessor or
       any of Lessor's representatives, would continue to be true on the date of
       the closing if all relevant facts and circumstances were known to Lessor
       and such representatives, (4) BNPLC shall find the Option Price
       acceptable after it is determined as provided in this Annex, and (5)
       BNPLC shall have been tendered the deed and other



                             EXHIBIT B-3 - PAGE 20
<PAGE>   61

       documents which are described in this Annex as documents to be delivered
       to BNPLC at the closing of BNPLC's purchase.

              (d) Closing of the purchase will be scheduled on the first
       Business Day following thirty days after the Option Price is established
       in accordance with the terms and conditions of this Annex and after any
       approvals described in subparagraph (a) above are obtained, and prior to
       closing BNPLC's occupancy of the GL Property shall continue to be subject
       to the terms and conditions of this Ground Lease, including the terms
       setting forth BNPLC's obligation to pay rent. Closing shall take place at
       the offices of any title insurance company reasonably selected by BNPLC
       to insure title under the title insurance policy described below.

              (e) Any transfer taxes or notices or registrations required by law
       in connection with the sale contemplated by this Annex will be the
       responsibility of Lessor.

              (f) Lessor will deliver a certificate of nonforeign status to
       BNPLC at closing as needed to comply with the provisions of the Foreign
       Investors Real Property Tax Act (FIRPTA) or any comparable federal, state
       or local law in effect at the time.

              (g) Lessor will also pay for and deliver to BNPLC at the closing
       an owner's title insurance policy in the full amount of the Option Price,
       issued by a title insurance company designated by BNPLC (or written
       confirmation from the title company that it is then prepared to issue
       such a policy), and subject only to standard printed exceptions which the
       title insurance company refuses to delete or modify in a manner
       acceptable to BNPLC and to Permitted Encumbrances.

              (h) Lessor shall also deliver at the closing all other documents
       or things reasonably required to be delivered to BNPLC or by the title
       insurance company to evidence Lessor's ability to transfer the GL
       Property to BNPLC.

       If Lessor and BNPLC do not otherwise agree upon the amount of the Option
Price within twenty days after BNPLC exercises the Option, the Option Price
shall be determined in accordance with the following procedure:

                     (1) Lessor and BNPLC shall each appoint a real estate
              appraiser who is familiar with properties in the vicinity of the
              Land and who has not previously acted for either party. Each party
              will make the appointment no later than ten days after receipt of
              notice from the other party that the appraisal process described
              in this Annex has been invoked. The agreement of the two
              appraisers as to the Option Price will be binding upon Lessor and
              BNPLC. If the two appraisers cannot agree upon the Option Price
              within ten days following their appointment, they shall within
              another ten days agree upon a third real estate appraiser.
              Immediately thereafter, each of the first two appraisers will
              submit his best estimate of the appropriate Option Price (together
              with a written report supporting such estimate) to the third
              appraiser and the third appraiser will choose between the two
              estimates. The estimate of Option Price chosen by the third
              appraiser as the closest to the prevailing fair market value will
              be binding upon



                             EXHIBIT B-3 - PAGE 21
<PAGE>   62

              Lessor and BNPLC. Notification in writing of the Option Price
              shall be made to Lessor and BNPLC within fifteen days following
              the selection of the third appraiser.

                     (2) If appraisers must be selected under the procedure set
              out above and either BNPLC or Lessor fails to appoint an appraiser
              or fails to notify the other party of such appointment within
              fifteen days after receipt of notice that the prescribed time for
              appointing the appraisers has passed, then the other party's
              appraiser will determine the Option Price. All appraisers selected
              for the appraisal process set out in this Annex will be
              disinterested, reputable, qualified real estate appraisers with
              the designation of MAI or equivalent and with at least 5 years
              experience in appraising properties comparable to the Land.

                     (3) If a third appraiser must be chosen under the procedure
              set out above, he will be chosen on the basis of objectivity and
              competence, not on the basis of his relationship with the other
              appraisers or the parties to this Ground Lease, and the first two
              appraisers will be so advised. Although the first two appraisers
              will be instructed to attempt in good faith to agree upon the
              third appraiser, if for any reason they cannot agree within the
              prescribed time, either Lessor and BNPLC may require the first two
              appraisers to immediately submit its top choice for the third
              appraiser to the then highest ranking officer of the California
              Bar Association who will agree to help and who has no
              attorney/client or other significant relationship to either Lessor
              or BNPLC. Such officer will have complete discretion to select the
              most objective and competent third appraiser from between the
              choices of each of the first two appraisers, and will do so within
              ten days after such choices are submitted to him.

                     (4) Either Lessor or BNPLC may notify the appraiser
              selected by the other party to demand the submission of an
              estimate of Option Price or a choice of a third appraiser as
              required under the procedure described above; and if the
              submission of such an estimate or choice is required but the other
              party's appraiser fails to comply with the demand within fifteen
              days after receipt of such notice, then the Option Price or choice
              of the third appraiser, as the case may be, selected by the other
              appraiser (i.e., the notifying party's appraiser) will be binding
              upon Lessor and BNPLC.

                     (5) Lessor and BNPLC shall each bear the expense of the
              appraiser appointed by it, and the expense of the third appraiser
              and of any officer of the California Bar Association who
              participates in the appraisal process described above will be
              shared equally by Lessor and BNPLC.

                           BILL OF SALE AND ASSIGNMENT

       Reference is made to: (1) that certain Purchase Agreement (Phase IV Land)
between BNP Leasing Corporation ("ASSIGNOR") and Network Appliance, Inc., dated
as of October 2, 2000, (the "PURCHASE AGREEMENT") and (2) that certain Lease
Agreement (Phase IV - Land) between Assignor, as landlord, and Network
Appliance, Inc., as tenant, dated as of October 2, 2000 (the "LAND LEASE").
(Capitalized terms used and not otherwise defined in this document are intended
to have the meanings assigned to them in the Common Definitions and Provisions
Agreement (Phase IV - Land) incorporated by reference into both the Purchase
Agreement and Land Lease.)

       As contemplated by the Purchase Agreement, Assignor hereby sells,
transfers and assigns unto [NAI OR THE APPLICABLE PURCHASER, AS THE CASE MAY
BE], a _____________ ("ASSIGNEE"), all of Assignor's right, title and interest
in and to the following property, if any, to the extent such property is
assignable:

       (a) the Land Lease;

       (b) any pending or future award made because of any condemnation
affecting the Property or because of any conveyance to be made in lieu thereof,
and any unpaid award for damage to the Property and any unpaid proceeds of
insurance or claim or cause of action for damage, loss or injury to the
Property; and

       (c) all other property included within the definition of "Property" as
set forth in the Purchase Agreement.

Provided, however, excluded from this conveyance and reserved to Assignor are
any rights or privileges of Assignor under the following ("EXCLUDED RIGHTS"):
(1) the indemnities set forth in the Land Lease, whether such rights are
presently known or unknown, including rights of the Assignor to be indemnified
against environmental claims of third parties as provided in the Land Lease
which may not presently be known, (2) provisions in the Land Lease that
establish the right of Assignor to recover any accrued unpaid rent under the
Land Lease which may be outstanding as of the date hereof, (3) agreements
between Assignor and "BNPLC's Parent" or any "Participant," both as defined in
the Land Lease, or any modification or extension thereof, or (4) any other
instrument being delivered to Assignor contemporaneously herewith pursuant to
the Purchase Agreement. To the extent that this conveyance does include any
rights to receive future payments under the Land Lease, such rights ("INCLUDED
RIGHTS") shall be subordinate to Assignor's Excluded Rights, and Assignee hereby
waives any rights to enforce Included Rights until such time as Assignor has
received all payments to which it remains entitled by reason of Excluded Rights.
If any amount shall be paid to Assignee on account of any Included Rights at any
time before Assignor has received all payments to which it is entitled because
of Excluded Rights, such amount shall be held in trust by Assignee for the
benefit of Assignor, shall be segregated from the other funds of Assignee and
shall forthwith be paid over to Assignor to be held by Assignor as collateral
for, or then or at any time thereafter applied in whole or in part by



                               EXHIBIT C - PAGE 1
<PAGE>   64

Assignor against, the payments due to Assignor because of Excluded Rights,
whether matured or unmatured, in such order as Assignor shall elect.

       Assignor does for itself and its successors covenant and agree to warrant
and defend the title to the property assigned herein against the just and lawful
claims and demands of any person claiming under or through a Lien Removable by
BNPLC, but not otherwise.

       Assignee hereby assumes and agrees to keep, perform and fulfill
Assignor's obligations, if any, relating to any permits or contracts, under
which Assignor has rights being assigned herein.

       IN WITNESS WHEREOF, the parties have executed this instrument as of
_______________, _____.

       WHEREAS, pursuant to that certain Purchase Agreement (Phase IV - Land)
(herein called the "Purchase Agreement") dated as of October 2, 2000, by and

                                FIRPTA STATEMENT

       Section 1445 of the Internal Revenue Code of 1986, as amended, provides
that a transferee of a U.S. real property interest must withhold tax if the
transferor is a foreign person. Sections 18805, 18815 and 26131 of the
California Revenue and Taxation Code, as amended, provide that a transferee of a
California real property interest must withhold income tax if the transferor is
a nonresident seller.

       To inform [NAI OR THE APPLICABLE PURCHASER] (the "Transferee") that
withholding of tax is not required upon the disposition of a California real
property interest by transferor, BNP Leasing Corporation (the "Seller"), the
undersigned hereby certifies the following on behalf of the Seller:

       1. The Seller is not a foreign corporation, foreign partnership, foreign
trust, or foreign estate (as those terms are defined in the Internal Revenue
Code and Income Tax Regulations);

       2. The United States employer identification number for the Seller is
_____________________;

       3. The office address of the Seller is ______________
_________________________ _________________.

       4. The Seller is qualified to do business in California.

       The Seller understands that this certification may be disclosed to the
Internal Revenue Service and/or to the California Franchise Tax Board by the
Transferee and that any false statement contained herein could be punished by
fine, imprisonment, or both.

       The Seller understands that the Transferee is relying on this affidavit
in determining whether withholding is required upon said transfer.

       Under penalties of perjury I declare that I have examined this
certification and to the best of my knowledge and belief it is true, correct and
complete, and I further declare that I have authority to sign this document on
behalf of the Seller.

       Dated: ___________, ____.
