Initials lessor:                                                Initials lessee:


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:


         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.

- --------------------------------------------------------------------------------
Initials lessor:                                                Initials lessee:


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
