                          GENERAL TERMS AND CONDITIONS

I.   GENERAL: lodged at the office of the court of Utrecht on 10th April 1984,
              where registered under number 230/84.

         The Lessor guarantees that the consent required for this tenancy
agreement has been obtained from the mortgagees.

II.  RENT

         A. The rent shall be paid in legal Dutch currency or by remittance into
a bank or Girobank account to be indicated by the lessor. Payment shall be made
such as to enable the lessor to dispose of the money latest on the due date of
the respective instalment of rent. 

         B. Whenever it is agreed that value added tax shall be charged, the
following shall apply;

_    The tenant irrevocably authorizes the lessor to lodge the petition, also in
     his, the tenant's, name, referred to in subsection b, fifth, of paragraph 1
     of section 11 of the 1968 Sales Tax Act, to the effect that value added tax
     may be charged on the rent referred to in paragraph 1 clause 3 of the
     tenancy agreement.

_    In the event the lessor proves that dismissal of the above petition is due
     to the tenant, the rent shall be increased by the amount of value added tax
     that would be payable if the petition had been granted.

     The same shall apply if the petition is granted as at a later date than the
     date asked for, albeit only for the period expiring on the date of
     commencement of the taxed letting.

_    In the event the tenant proves that dismissal of the petition is due to the
     lessor, the rent referred to in paragraph 1 of clause 3 of the tenancy
     agreement shall not be increased by value added tax.

_    The value added tax due shall be paid simultaneously with the rent. In the
     event of a sale of the property hired by the lessor, the new owner and
     tenant shall be bound to what has been agreed between the lessor and the
     tenant with regard to the value added tax, unless the new owner and tenant
     should agree to the contrary.

   13
         c. The annual adjustment of the rent shall take place in accordance
with the modification of the price-index figure of family consumption, series of
wage-earning families having in 1985 a family income below the maximum wage
level for entitlement to national health insurance, fixed by the Central
Statistical Office on the most recent time basis. The new rent shall be obtained
each time by multiplying the current rent in force until the date of adjustment
of this ruling rent by a factor to be obtained by dividing the average
price-index figure of the calendar year preceding the date of adjustment of the
rent by the average price-index figure of the calendar year preceding the date
of commencement of the then prevailing rent and by rounding off the figure so
obtained to three decimal places.

Consequently,   the new rent shall be: price-index figure for the calendar 
                year preceding the date of commencement of the new rent

prevailing rent X ____________________________________________________________
                price-index figure for the calendar year preceding the date
                of commencement of the rent in force. 

         D. If the Central Statistical Office suspends the announcement of the
said price-index figure or changes the basis of its calculation, a possibly
comparable index figure shall be applied.

In the case of difference of opinion on this matter, the willing party may ask
the Central Statistical Office for a judgment that shall be binding upon the
parties. Any expenses connected therewith shall be borne by the parties on a
fifty-fifty basis.

         E. If either of the parties wants to make use of the power to revise
the rent, he shall notify the other party accordingly by registered letter with
acknowledgement of receipt latest six months prior to the date on which the
revision shall become effective. Failing the parties to come to an
understanding within two months from receipt of the notice referred to above,
the rent shall be fixed by three estate agents, members of the Dutch
Association of Estate Agents NVM. Of these three agents each party shall
nominate one within a fortnight from the date on which a party shall have
received a request to this end from the other party.

The third agent shall be nominated by these two agents within eight days from
their acceptance of the nomination. The judgment of third agent shall be
decisive failing agreement between the agents on the rent to be fixed.

Failing one of the parties to nominate an agent or failing both nominated agents
to agree on the nomination of a third agent, the willing party may ask the
nomination from the chairman of the Chamber of Commerce and Factories of the
district in which the estate is located, in the first instance of the two agents
and in the second instance of one agent. The agents' fees shall be borne by the
parties on a fifty-fifty basis. The agents shall issue their report within six
weeks from definite nomination.

         B.  The tenant shall be obliged to supply the lessor each year with a
specified summary of the expenses referred to in the preceding paragraph.

opinion there is a reason for it, extend, reduce or annul the supplies and
services both in terms of type and volume.

IV.  THE PROPERTY HIRED

         A.  The tenant shall arrange to obtain licences and/or exemptions, if
required, for the conduct of business, while their cancellation or withdrawal
can never cause the tenancy agreement to be annulled or nullified nor any other
action against the lessor.

         B.  If the lessor and/or co-tenant(s) should be charged with a higher
premium for fire insurance in connection with the nature and/or conduct of
tenant's business, the tenant shall refund to the lessor and/or co-tenant(s)
such extra premium calculated in respect of the aggregate insured sum.

The lessor shall be free in fixing the sum to be insured, in electing the
insurance company/companies and in judging the fairness of the premium due.

         C.  Any taxes and duties due for items fitted by the tenant or his
legal predecessor, the property tax for account of factual use as well as the

lessor.

V. THE USE

         A. The tenant declares to be sufficiently familiar with the property
hired, not requiring any further description thereof. The lessor shall not be
liable for the consequences of apparent or latent defects of the property hired.

Such defects shall also include the defective functioning or failure to
function of the piping and installations serving for the supply and discharge
of heat, water and electricity.

         B. The tenant shall use the property hired as a tenant should and in
conformity with the purpose stated in clause 6 of the tenancy agreement, while,
in addition, he shall, in line with this purpose, provide and keep it provided
with adequate inventory c.q. the required fittings and furniture. The tenant
shall not be free without written consent from the lessor, to change the
purpose of the property hired.

The tenant shall be obliged to take care that he, or any third party working
for his and/or any member of the household, causes no inconvenience to users of
the premises involved c.q. the adjoining premises. The tenant undertakes to
conduct his business as a tenant should.

         C. Without the previous written consent of the lessor, the tenant
shall not have the property hired used, neither wholly nor partly, by any third
party or sublet it to any third party.

In the event the tenancy rights fall under an undivided estate, the transfer of
the tenancy rights, following allotment in the case of partition of property,
shall take place only with previous written consent of the lessor. The tenant
shall, without the previous written consent from the lessor, be prohibited from
bringing any tenancy right under the present contract into a company,
partnership and the like, or from making use of his tenancy rights in each
company or partnership.

   17
         D. The tenant shall not provide, change or remove anything in or to the
property hired, nor to the piping and discharge systems belonging to it, unless
with the previous explicit written consent of the lessor. The tenant shall be
liable to ensure that in carrying out the works, the pertinent requisites made
or to be made by the authorities are complied with, and also that any licences
required shall be obtained.

         Whatever the tenant shall have provided, changed or removed in or to
the property hired, and this entirely for his own risk and account, shall be
left intact by him on expiry of the tenancy without the tenant's right to claim
any corresponding compensation from the lessor.

         Any exception to this rule shall be valid only if, in granting the
consent referred to in the first sentence of this section, the lessor shall have
reserved his right to require the tenant, on expiry of the tenancy, to bring the
property hired in the condition in which it was on commencement of the tenancy
agreement.

         E. The tenant shall not provide any advertisements or signs without
having obtained the explicit written consent of the lessor.

         The lessor shall for himself and/or for third parties reserve the right
to provide advertisements to or on the property hired or the complex to which
the property hired belongs, to the extent that this shall not affect the
tenant's conduct of business c.q. causes him inconvenience.

         Without the explicit written consent of the lessor, no aerials and
piping shall be provided on or to the property hired. The tenant shall forfeit 
a penalty of NLG 250.-- for each day on which he maintains an aerial and/or 
a pipeline without the previous written consent of the lessor.

         The tenant shall ensure that no people are allowed on the roof and that
no objects are put on it.

         No items shall be provided in or to the property hired that may cause
damage to it.

VI.  MAINTENANCE AND REPAIRS

         A. The tenant shall be obliged to continue keeping in proper state of
maintenance the object hired, including the sanitary jettings, which he has
accepted in good condition, with pipelines and discharge system, and to have the
chimneys swept for his account.

         The tenant shall, for his own account, substitute as soon as possible
by quite identical new panes, all glass panes of the property hired, including
plate glass windows or shop-windows, which should break or be damaged during the
tenancy.

         In the case of frost or snow the tenant shall take all steps to avoid
damage to the property hired or to property of any third party, in particular he
shall during frosty weather take all measures to prevent heating systems and/or
hot water plants (if and when available in the property hired), pipeline and
discharge systems from freezing. The tenant shall be liable for the proper and
professional maintenance and use of all facilities and installations existing in
or to the property hired.

         B. The repairs referred to in section 1619 of the Civil Code as
running for the tenant's account shall also include those to door/window
furniture, sanitary fittings, electric installation and gas plant, awnings,
partition walls, ceiling covering, as well as ventilating and airconditioning
plant(s) and central heating system(s) (including the renewal of radiator
cocks).

         In the event the lessor wants to institute investigations into the
advisability to have repairs carried out as referred to in clause 1591 of the
Civil Code, or if he wants to have such repairs prepared or carried out, or if
works have to be done on behalf of other tenants or occupants, the tenant shall
be obliged to give the lessor, or the person reporting to him in the name of the
lessor, as soon as possible but latest within 24 hours from receiving the notice
to be given to the tenant on the part of the lessor, access to this effect to
the property hired and to enable him to carry out the intended investigations
and/or the works deemed necessary by the lessor, without being entitled to make
any condition in this respect nor to require any consideration.

         This shall hold good regardless of the duration of such works.

VII. DEFAULT

         A. If the tenant, on written demand, is in default in the fulfilment of
any obligation imposed on him by the law, the local regulations and customs
and/or the present contract, the lessor shall be entitled to notify him to
terminate the tenancy forthwith before expiry, without giving any further notice
or judicial interposition to this effect being required, so far as permitted by
law. Alternatively, in the event of the above demand, such notification may
already take place conditionally, namely if such demand is ignored.

         The costs of demand and notification shall run for the tenant's
account, the former also if on its receipt the tenant as yet complies with his
obligations.

         B. The tenant shall be bound to compensate the lessor for any damage
sustained by the latter due to the default and/or the termination of tenancy
before expiry referred to above, without prejudice to both parties' obligation
to meet with any liability that should occur for each of them until the expiry
of the tenancy.

         C. Any cost, both in and out of court, caused to the lessor by the
tenant's default against any of the clauses of this contract, shall run for the
tenant's account. Any extrajudicial costs running for the tenant's account,
shall, in the case of default in payment of the rent, be fixed by the parties
at at least 15% of the rent due for payment.

         D. In the case of non-payment of rent the lessor shall be entitled,
without any demand and/or giving further notice being required, to charge an
interest of 1% per month (or part of a month) on the rent in arrears.

         E. These stipulations shall leave intact the lessor's power to demand
at law, under the provisions of section 1302 of the Civil Code, annulment of
the tenancy agreement on the ground of default by the tenant, coupled with
indemnification and clearance of the property hired.

         A. The security c.q. bank guarantee shall serve as security:

- -    for whatever the tenant, under the present contract or its extension, if
     any, shall become due to the lessor or his successor(s) in title,
     (including any indemnification to be for the tenant's account as well as
     the interest and costs referred to in clause VII).

- -    as well as for any financial damage sustained by the lessor in the case of
     termination of the tenancy agreement before its expiry, due to the tenant's
     bankruptcy, to the extent that no recovery against the tenant and/or the
     estate shall be possible.

         B. If during the currency of the tenancy agreement the lessor is forced
to call on the security c.q. bank guarantee, the tenant shall pay same up as
soon as possible but anyway within two weeks.

         C. The bank guarantee shall remain valid until at least three months
from expiry of the tenancy agreement.

         D. No interest shall be paid on the security.

         E. The tenant shall not be entitled to require any amount due to the
lessor to be set off against the security.

         F. On expiry of the tenancy, the clearance and the delivery, the lessor
shall fix as soon as possible the amount of his claims, and, so far as possible
after setting off same against the security, pay over the balance of the
security to the tenant, c.q. give his consent to the tenant to withdraw the bank
guarantee.

IX. DELIVERY

         The tenant shall renounce the rights which he may enforce against the
lessor, in the event the latter is unable to place the property hired at the
tenant's disposal on the agreed date, provided this is due to any act or default
of a third party, if and to the extent that the lessor cannot reasonably be
blamed for this.

the present tenancy agreement.

XI.  TERMINATION OF THE TENANCY AND A POSSIBLE PURCHASE

         A. For a period of twelve months prior to termination of the tenancy,

tenant shall be obliged to permit the property hired to be inspected from 14.00
to 16.00 hours on every Tuesday and Thursday, alternatively, if local customs so
require, on two other days of the week and, in addition, on the date of the
public sale, as well as to permit notices of the public sale, selling or letting
boards or notices being put up.

         B. On termination of the tenancy, the tenant shall be obliged to timely
vacate the property and, with due observance of clause V D, to place same in
good condition and properly cleaned at the lessor's disposal, as well as to hand
the keys over to the lessor.

keys in time, he shall be entitled to gain entrance into the property hired at
the tenant's expense, without prejudice to the tenant's obligation to indemnify
him for any damage that should occur due to this failure.

Re: Newbuilding industrial building Inventair at Nieuwegein.


Woarden, 12th April 1989

Dear Mr van Wijk,

With reference to our statement made during the meeting of 16th December 1988
that the amendments required by you, as reproduced on the drawing no. 88027-DO-1
dated 14-12-1988, had still to be looked into by our designer to establish their
consequences, we have now pleasure in enclosing the construction drawings no.
88290 pages A and B dated 16-03-89 and 15-03-1989.

Due to the changed column lay-out in connection with the routing and machine
scheduling as well as the addition of the extra intermediate floors and the
fitting of a roof structure on behalf of the mechanical ventilation, the
quantity of steel has increased by approximately 35,000 kilos.

The extra charge involved will in terms of annual rent amount to NLG 8,850. -
excluding V.A.T.

We Trust that the above information will be sufficient for your purpose.

Yours faithfully,

Esbouw Projectmanagement B.V.

Re: adjustment rent Parkerbaan, of Nieuwegein.

Dear Sirs,

In accordance with what is laid down in the tenancy agreement signed with you in
respect of the above object, the rent will be adjusted every year on 1st
December on the basis of the price-index figure of family consumption, series of
wage-earning families, as published by the Central Statistical Office.

Proceeding from the clause included in the tenancy agreement we have calculated
the new yearly rent as follows:

- -    index figure calendar year 1991 - 107.7 (1985=100)
- -    index figure calendar year 1990 - 103.7 (1985=100)

New rent: 107.7/103.7 - 1.039 x NLG 336,456.17 = NLG 349,577.96

Per quarter: NLG 87,394.49.

The next rent invoices will be based directly on the new yearly rent.

We trust that our information is sufficient for your purpose.

Yours faithfully,

sgd.: illegible
