<PAGE>

9.1.2    In the event that it was agreed that sales tax will be charged on the
         rent, the lessee and the lessor explicitly declare that the starting
         point for determining the rent was that the lessee will continue to use
         the leased space or cause it to be used for purposes for at least the
         percentage determined by law or a minimum percentage to be determined
         at a later date for activities which entitle the lessee to deduct sales
         tax, in such a way that the parties can opt for taxed rent.

9.1.3    The lessee and lessor will make use of the possibility by virtue of
         Notification 45, decision of 24 March 1999, no. VB 99/571 to waive the
         right to submit a joint request to opt for rent subject to sales tax
         and to limit it to a statement to be filled in and signed by the
         lessee, which statement forms an integral part of the present lease.
         The stipulations of Article 5.3 of the lease are therefore hereby
         declared to be inapplicable.

9.1.4    The lessee will send a signed and completed statement to the lessor in
         accordance with a model to be made available by the lessor not later
         than on the date of signing this lease from which it appears that the
         lessee will use the leased space or have it used for purposes for which
         a right to make a complete or practically complete deduction of sales
         tax exists as laid down in Section 15 of the Wet op de Omzetbelasting
         1968 (Sales Tax Act 1968).

9.1.5    The lessee hereby declares that its financial year runs from January 1
         to December 31.

9.1.6.a  If the decision to grant taxed rent should be cancelled because the
         lessee no longer uses the leased space or causes it to be used for
         activities which entitle it to deduct sales tax, the lessee will no
         longer owe the lessor or its successor(s) in title sales tax on the
         rent, but the lessee will owe the lessor or its successor(s) in title
         in addition to the rent exclusive of sales tax commencing on the date
         on which the decision to grant taxed rent has been cancelled by way of
         a separate payment such an amount that the latter is fully compensated
         for:

         I.    The sales tax which the lessor or its successor(s) in title is no
               longer allowed to deduct as a result of the cancellation of the
               possibility to deduct sales tax from the operating costs of or
               from investments in the leased space.

         II.   The sales tax which the lessor or its successor(s) in title has
               to pay to the tax authorities as a result of the cancellation of
               the possibility to deduct sales tax due to a recalculation of the
               taxed rent as referred to in Section 15, subsection 4 of the Wet
               op de Omzetbelasting 1968 or revision as referred to in Sections
               11, 12 and 13 of the Uitvoeringsbeschikking Cmzetbelasting 1968
               (Sales Tax (Implementation) Decree 1968).

         III.  All other loss which the lessor or its successor(s) in title
               incurs as a result of the cancellation of the possibility to
               deduct sales tax.

9.1.6.b  The financial loss incurred by the lessor or its successor(s) in title
         as a result of the cancellation of the option for taxed rent will be
         paid by the lessee to the lessor or its

--------------------------------------------------------------------------------
Initials lessor:                                                Initials lessee:
<PAGE>

         successor(s) in title every time together with the periodic rent
         payments and will, with the exception of the loss as referred to under
         I in 9.1.6.a, if possible be equally divided by means of an annuity
         over the remaining periods of the current lease term, but will be due
         and payable in full and immediately by the lessee if the lease is
         terminated prematurely, for whatever reason.

9.1.7    The stipulation referred to in II under 9.1.6.a will not apply if at
         the time when the present lease is concluded the revision period for
         deducting sales tax already paid with respect to the leased space has
         expired.

9.1.8    The stipulations referred to under 9.1.6 also apply if at the time when
         the lease is concluded the lessee has not provided the lessor with a
         signed `Sales Tax statement' filled in and signed by the lessee, as
         referred to under 9.1.3. The stipulation of 15.2 of the General
         Conditions is consequently hereby declared to be inapplicable.

9.1.9    If a situation as referred to in 9.1.6 occurs, the lessor or its
         successor(s) in title will inform the lessee what amounts must be paid
         by the lessor or its successor(s) in title to the tax authorities and
         provide insight into the other losses as referred to in 9.1.6, with the
         exception of loss determined in advance as referred to in I under
         9.1.6.a. The lessor or its successor(s) in title will give its
         cooperation if the lessee wishes to have the specification of this
         additional loss made by the lessor or its successor(s) in title checked
         by an independent registered accountant. The costs of this will be at
         the lessee's expense.

9.1.10   In the event that the use to which the lessee puts the leased space or
         causes it to be put is not complied with in accordance with the
         purposes referred to under 9.1.2, the lessee will inform the lessor or
         its successor(s) in title of this by means of a signed statement within
         four weeks of the end of the financial year concerned. The lessee will
         also send a copy of this statement to the Sales Tax Inspectorate within
         the same period of time.

9.1.11   If the lessee does not fulfill the obligation to provide information as
         referred to under 9.1.3 or under 9.1.9 and/or does not comply with the
         obligation of occupation as referred to under 9.1.12 or if it turns out
         in retrospect that its assumptions were incorrect, and it turns out in
         retrospect that the lessor or its successor(s) in title has wrongly
         charged sales tax on the rent, the lessee shall be in default, and the
         lessor or its successor(s) in title shall be entitled to recover the
         resulting financial loss from the lessee. This loss concerns the full
         sales tax still due by the lessor or its successor(s) in title to the
         tax authorities plus interest and any increases as well as additional
         costs and loss. The stipulations in this paragraph contain an
         arrangement for compensation in the event that the taxed rent ceases to
         be applicable with retroactive effect, in addition to the arrangement
         set out in 9.1.6. The additional loss which results for the lessor or
         its successor(s) in title from the retroactive effect, will be payable
         by the lessee immediately, in full and as a lump sum. The lessor or its
         successor(s) in title will give its cooperation if the lessee wants to
         have the specification of this additional loss made by the lessor or
         its successor(s) in title checked by an independent registered
         accountant. The costs of this will be at the lessee's expense.

<PAGE>

9.1.12   The stipulations set out under 9.1.6, 9.1.8 and 9.1.10 will also apply
         if the lessor or its successor(s) in title is confronted with a loss
         after the termination of the lease, whether premature or not, due to
         the cancellation of the taxed rent agreed upon by the parties. This
         loss will then be payable by the lessee to the lessor or its
         successor(s) in title immediately, in full and as a lump sum.

9.1.13   Without prejudicing the other relevant stipulations in the lease, the
         lessee will in any event put the leased space into use or cause it to
         be put into use before the end of the financial year in which it
         started to lease the space with application of the right of opting for
         taxed rent.

Payments

9.2      Payments by the lessee must be made by automatic transfer.

Carrying out work in the leased space

9.3      The lessee is permitted to carry out fitting-out work from October 1,
         2000 (based on the planning of the building work by Slavenburg's
         Bouwbedrijven) without rent being payable to the lessor. The lessee
         will ensure its fitting-out work will not cause any nuisance to the
         fitting-out work carried out by the lessor's (sub)contractor(s). In
         consultation with Maasstede Vastgoed Ontwikkeling and Slavenburg's
         Bouwbedrijven, the lessee will submit to the lessor the standards and
         specifications (together with drawings) of the fixtures and fittings to
         be installed in the leased space for its approval. The lessee will not
         be permitted to carry out work in or on the leased space before the
         lessor has granted its written permission for the proposed alterations.
         Lessor shall not unreasonably withhold its approval.

Commencement date of the lease

9.4      The commencement date of the lease as mentioned in Article 3.1 and in
         accordance with the rent payment obligation of the lessee is a target
         date. The commencement of the lease will be 6 (six) months after the
         date in Article 9.3 mentioned "carrying out work in the leased space".
         When the "carrying out work in the leased space" moves in time, the
         commencement date of the lease will be so much earlier or later subject
         to a period of 6 (six) months. The commencement date is a goal date. If
         goal date is not met, the rent date is moved along accordingly to six
         (6) months from fitting-out date.

Level of outfitting

9.5      The leased space will be delivered by the lessor in accordance with:

         a.    the drawings WE250f, WE251d, WE252d, WE253c, WE254e, WE255f and
               WE256c, all dated March 22, 2000 of Group 5 Van Der Ven (project
               number 98p22) and;

         b.    schedule of alterations Equinix dated April 14, 2000 to
               specification number 372-2 dated December 1, 1999.

Publicity with respect to the lessee and the leased space

9.6      For security reasons, the lessee and the lessor will draw up rules in
         joint consultation providing for a manual for the provision, in any
         way, of information and publicity matters with respect to the lessee,
         the nature of the leased space and the activities in the leased space
         of the lessee and its clients.

Subletting and reletting

9.7      The lessee has the right to sublet the leased space or parts thereof to
         companies belonging to the same group, including parent, sister or
         subsidiary companies as that of the lessee in accordance with the
         definition of Section 2:24 (a) and (b) of the Netherlands Civil Code,

       charges.

       period of five consecutive years and after the lessee has shown a
       positive result on the basis of the EBITDA measurement system for the
       last three consecutive years of the said five year period.

10.7   After the conditions mentioned in subsection 10.6 have been fulfilled,
       the rental bank guarantee will be decreased further with an amount equal
       to 1 month rent (including service charges and VAT) if, the lessee has
       shown a positive result on the basis of the EBITDA measurement system in
       each following year after the five years referred to in subsection 10.6

         state and condition in which it was originally planned to be built,
         which means that the equipment which were not installed or which were
         replaced by the lessee's own equipment shall have to be installed and

         of the lessee.

Revision / assessment of the rent against the market rent

11.1     Without prejudice to the stipulations mentioned in Article 4.3 both
         parties are entitled to require an assessment of the rent against the
         market rent, for the first time after a period of 15 (fifteen) years
         and subsequently after each period of 5 (five) years.

11.2     The market rent is the rent amount of similar storage space on the
         spot. If one of the parties wishes a revision, it will notify the other
         party by certified mail 6 months prior to the date the revised market
         rent will have to commence. The revision will never lead to a lower
         lease price than the initial lease price at the time of the
         commencement date of this lease agreement.

11.3     In case parties will not have reached agreement about the lease price

          will, within 2 (two) weeks after their appointment, jointly appoint a
          third expert. The 3 (three) experts will determine the lease price
          within 1 (one) month after the appointment of the third expert.

11.4      In the case lessee and lessor agree that 1 (one) expert will suffice
          and the appointment of this one expert has been agreed to in writing,
          this one expert will obligatorily determine the lease price contrary
          to the aforementioned stipulations.

11.5      When it becomes apparent that the expert has not been appointed within
          the stipulated period or that the experts have not determined the
          lease price within the stipulated period then the subsequent party can
          apply to the subdistrict court, within whose jurisdiction the leased
          space is located, to determine the revision of the lease price.

                              Title and Condition
                              -------------------

     4.1  Title to the Real Property. Seller shall convey to Buyer good and
          --------------------------
marketable fee title to the Real Property, by a duly executed and acknowledged
Grant Deed (the "Grant Deed") in the form of Exhibit E attached hereto, free and
clear of liens, encumbrances, leases, easements, restrictions, rights, covenants
and conditions, except the following (the "Permitted Exceptions"): (a) the
matters shown as exceptions 1 (lien of property taxes and assessments not yet
delinquent), 2 (as modified by that certain letter dated May 15, 2000 from
William Murray to Glenn Snyder and Christine Shen (the "Title Letter")), 3, 4,
5, 6 and 7 (as modified by the Title Letter) in the Preliminary Report, (b)
matters shown by the ALTA Survey or by a physical inspection of the Real
Property, (c) any liens, assessments or other liabilities arising by virtue of
the Real Property's being located within any present or future improvement
district or assessment district, and (d) any other matters created, permitted or
approved by Buyer. Buyer has engaged the Surveyor to produce an ALTA/ACSM Survey
of the Real Property (the "ALTA Survey"), which shall be complete prior to
Closing but in no event later than June 15, 2000. Buyer shall pay the cost of
the ALTA Survey. Buyer and Seller acknowledge that the ALTA Survey could reveal
a Material Encumbrance (as hereinafter defined) not shown on the Boundary
Survey. In such event, Buyer and Seller agree that (i) if the Material
Encumbrance results in an FAR Reduction (as hereinafter defined) of less than
ten percent (10%), then the Purchase Price shall be reduced by a percentage
equal to the FAR Reduction and (ii) if the Material Encumbrance results in an
FAR Reduction of more than ten percent (10%), then Buyer shall have the right to
(x) reduce the Purchase Price by ten percent (10%) and purchase the Real
Property at such reduced Purchase Price or (y) terminate this Agreement and
receive a refund of the Deposit. As used herein, the term "Material Encumbrance"
shall mean an encumbrance on the Real Property that has the effect of reducing
the floor area ratio that can be developed by Buyer on the Real Property and the
term "FAR Reduction" shall mean the percentage by which the floor area ratio
that can be developed by Buyer on the Real Property is reduced as a result of
any Material Encumbrance. Seller shall transfer to Buyer good title to the
Permits and the Agreements, by a duly executed Assignment (the "Assignment") in
the form of Exhibit F attached hereto, free and clear of liens, security
interests and adverse claims. Buyer's acceptance of title from Seller subject to
future assessment districts does not constitute Buyer's approval of any such
future assessment districts.

     4.2  Acceptance of Title. Buyer's acceptance of the Grant Deed from Seller
          -------------------
for the Real Property at the Closing on the Closing Date and the issuance of a
title insurance policy to Buyer by the Title Company on the Closing Date shall
conclusively establish that Seller conveyed the Real Property to Buyer as
required by this Agreement and shall discharge in full Seller's obligations
under section 4.1 hereof with respect to title to the Real Property.

     4.3  Condition of the Property. Except for the express representations and
          -------------------------
warranties of Seller set forth in section 5.1 hereof and in Seller's Closing
Certificate (as hereinafter

                                      -3-
<PAGE>

defined), and except for the express covenants of Seller in this Agreement,
Buyer is acquiring the Property "AS IS, WHERE IS, AND WITH ALL FAULTS," without
any covenant, representation or warranty of any kind or nature whatsoever,
express or implied, and Buyer is relying solely on Buyer's own investigation of
the Property. Except for such express representations, warranties and covenants,
Seller makes no covenants, representations or warranties, express or implied, of
any kind or nature whatsoever with respect to the Property. Buyer acknowledges
that defects, deficiencies or flaws may exist in the quality, legal compliance,
physical condition or general utility of the Property and Buyer acknowledges
that Buyer has been given the opportunity to investigate and evaluate any such
defects, deficiencies and flaws. Buyer expressly assumes all risks of any such
defects, deficiencies and flaws and Buyer agrees that Seller shall have no
liability whatsoever for any such defects, deficiencies or flaws, except only
for such express representations and warranties made by Seller in section 5.1
hereof and in Seller's Closing Certificate and except for the express covenants
of Seller in this Agreement. Without limiting the foregoing, in connection with
Buyer's investigation of the Real Property, Buyer has investigated the presence
of hazardous substances (as hereinafter defined) in, on or under the Real
Property and the violation of environmental laws (as hereinafter defined) at the
Real Property. As used in this Agreement, "hazardous substance" means any
substance or material that is described as a toxic or hazardous substance, waste
or material or a pollutant or contaminant, or words of similar import, in any
environmental law and "environmental law" means all federal, state and local
laws, ordinances, rules and regulations now or hereafter in force, as amended
from time to time, in any way relating to or regulating human health or safety,
or industrial hygiene or environmental conditions, or protection of the
environment, or pollution or contamination of the air, soil, surface water or
groundwater. Buyer hereby expressly, fully, forever and irrevocably waives and
releases all claims, demands, liabilities, losses and causes of action against
Seller that in any way (directly or indirectly) arise out of, result from or
relate to the presence of any hazardous substance in, on or under the Real
Property or the violation of any environmental law at the Real Property. Buyer
intends this Agreement to be a general release that covers all such claims,
demands, liabilities, losses and causes of action, whether known or unknown or
suspected or unsuspected. Buyer hereby waives all rights under California Civil
Code Section 1542, which provides:

                           A general release does not extend to claims
                  which the creditor does not know or suspect to exist
                  in his favor at the time of executing the release,
                  which if known by him must have materially affected
                  his settlement with the debtor.

Buyer agrees that this Agreement is a full and final general release of all such
claims, demands, liabilities, losses and causes of action against Seller.

     4.4  Assessment Districts. Buyer acknowledges that the City of San Jose is
          --------------------
reviewing the possibility of forming one or more assessment districts which may
include the Real Property. Buyer has satisfied itself as to the benefits and
burdens of such possible assessment districts, and agrees that Seller shall have
no liability to Buyer with respect to any assessments or other obligations
relating thereto.

reasonably required by IBM.
