|Unforeseeable expenses |  | Where, following the execution of this Agreement, unforeseen increases in costs arise in relation to the property as a consequence of:  a) the introduction of, or increases in taxes, charges or duties levied
specifically on the property as a result of decisions taken by Parliament, Government, municipalities, or other relevant authorities;  b) general rebuilding or the like of property which do not relate only to the premises and which the Lessor is obliged to execute as a result of
decisions of the Parliament, Government, municipalities, or other relevant authorities;  The Lessee shall, from the time of the cost increase, reimburse the Lessor in relation to the proportion of the total annual increase in costs for the property represented by the premises.  The proportion represented by the premises is 2.06 percent. If the proportion has not been indicated,
it shall be comprised of the proportion of the total rents for premises (excluding any value-added tax) represented by the Lessees rent (excluding any value-added tax) at the time of the increase in costs. Regarding unleased premises, the
market rent for the premises shall be estimated.  Taxes in a) above does not
refer to value-added tax and property tax to the extent that reimbursement for this is paid as per agreement. Unforeseen costs means such costs that were not decided upon by the authorities as set forth in sections a) and b) at the time
of the signing of the Agreement. Reimbursement shall be paid in the same manner as set forth below for rental payments.

|Clause    |                 | Of the rent stipulated in the Lease Agreement  SEK 2,074,800 , 100% or SEK 2,074,800 shall constitute the base rent. During the
term of the Lease Agreement, a surcharge to the rent, constituting a certain percentage of the base rent, shall be payable with regard to changes in the consumer price index (using the total index for 1980 as a base) according to the
following:   For lease agreements commencing during the period 1/1  6/30
the base rent is deemed to be adjusted to the index level for that of the month of October the previous year.   For lease agreements commencing during the period 7/1  12/31 the base rent is deemed to be adjusted to the index level for the month of October of the same year.   The index level for the October that the base rent is deemed to be adjusted to, as shown
above, becomes the base figure unless otherwise agreed by designating a year as per the following. Alternative agreed base figure is the index level for the month of October2005.  Should the index level any following October have risen in relation to the base figure, the
surcharge shall be calculated on the percentage by which the index has changed in relation to the base figure. Future surcharges will be based on the changes in the index, and the rental change is to be calculated on the percentage change between
the base figure and the index level for the month of October in question.  The rent
payable shall nevertheless never be adjusted below the rent stipulated in the Lease Agreement. A change in the rent is always effective from January 1stfollowing an adjustment due to a recalculation following a change in the previous October Index.  The instructions in page 2 are applicable to the agreement.

Instructions in respect of Index Clause for premises

Base Rent

Whether all or a part of the rent stipulated in the Lease Agreement shall constitute the base rent, is a subject to negotiation, and can depend on the terms of the Lease Agreement (such as for example the rent amount
expressed as SEK/m2 per year and what other obligations the Lessee is responsible for, etc.).

Base Figure

The index level for the month of October that the base rent is deemed to be aligned to constitutes the base figure, unless otherwise agreed by designating a year (as per
conditions stated on page 1).

Comparison of index levels shall be done as soon as the annual October index is published. During recent years the October
index has been published by the middle of November.

Calculation of the surcharge



|1) | Calculate the difference between the relevant October index and the base figure.
|-- | --------------------------------------------------------------------------------



|2) | If the difference is positive, divide the difference by the base figure.
|-- | ------------------------------------------------------------------------



|3) | The surcharge is calculated by multiplying the base rent by this quotient.
|-- | --------------------------------------------------------------------------

Example

Calculation of the surcharge for 2002

Presume that the base rent is SEK 100,000 per year and is aligned to the consumer price index for October 1999, which is 259.7 (the base figure). The October index for 2001 is 269.1.



| | 1. | Calculate the difference between the index figure 269.1 and 259.7. The difference is positive and amounts to 9.4.
| | -- | -----------------------------------------------------------------------------------------------------------------



| | 2. | Divide 9.4 by 259.7 and multiply the quotient (without rounding-off) by the base rent SEK 100,000. The result is SEK 3,619.56, which according to the clause, becomes the surcharge
for 2002.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Alternative A: Assume that the consumer price index for October 2001 instead had been lower than the year before, for example
262.0 (the index for October 2000 was 262.6).

The Difference between the assumed index level 262.0 and the base figure 259.7 would still be positive
and amount to 2.3. The quotient between 2.3 and the base figure 259.7, multiplied by the base rent would have amounted to a surcharge of SEK 885.63. The total rent would however have been lower than for 2001.

Alternative B: Assume that the consumer price index for October 2001 had instead been lower than the base figure 259.7, for example 259.5.

The difference between 259.5 and the base figure 259.7 would then have been negative. No surcharge would apply. The rent stated in the Lease Agreement would apply.

| |  |   |  | The premises share of the property tax applying to premises in the property is deemed to be
         per cent. The Lessee shall provide reimbursement for his share of changes in the applicable property tax for premises that take effect after the signing of the Lease Agreement (irrespective of the
cause) to the extent that the tax exceeds the amount that is included in the rent as reimbursement for property tax.  Should the property tax be reduced/cease so that Lessees share of the reimbursement is less than that as per above, is included in the rent specified in the Lease Agreement, the rent shall nevertheless be
payable with at least the original amount. This means therefore, due to other clauses (e.g. index) contained in the Agreement that the total rent payable by the Lessee is/may be greater than the rent shown in the Lease
Agreement.

INSTRUCTIONS

1.

The
Clause was formulated in June 1995, i.e. before the time (normally January 1 1996) that the property tax for premises takes effect. The clause therefore has a wording that makes it possible to add it to agreements signed before tax is payable,
as well as agreements that are signed when taxes are in fact payable.

2.

The compensation shall pay for increased management costs irrespective of who in reality is liable to tax. The Property Owner/Lessor is liable to tax. If
the Property Owner/Lessor is a trading company the Partners were liable to tax, according to earlier regulations. But the surcharges were nevertheless payable to the Lessor. After January 1 1997 it is however the Trading Company that is liable
to the property tax.

3.

According to 19§ of the Leasing Law the rent amount hall  with a few exceptions - be determined in the Lease Agreement. If the leasing term of the Lease is determined and at least three years, further reservations,
indicating that the rent shall be payable with an amount that is determined according to other grounds for calculation, for example index regulation, apply. This also means that the term of the Lease must be determined and at least three
years for the Lessor to be able to take compensation for property tax with an amount that may vary as the tax changes. Furthermore the grounds for calculation must be indicated in the Agreement. A condition for clause is therefore that the Parties
indicate how big a share of the tax the Lessee shall compensate the Lessor for.

According to the regulations in force at
the time of the preparation of this clause, the tax consists of a certain percentage of the tax value of premises (both land and buildings). The information can be found in the annual tax information. The Lessees share of the tax for the
premises can be determined as the ratio between the rent of the Lessee and the total rent amount of the property.

The
calculation method chosen by the Parties becomes a matter of negotiation. Also other bases of calculation can be used. To simplify the Lessees share should remain unchanged throughout the term of the Lease and thus independent of among other
how the tax might come to be calculated in the future as well as changes of the leasing market.

It is advisable to indicate
how the share of the premises has been calculated in therefore intended place. If this information were not to be interred, it shall nevertheless not mean that the agreement becomes invalid. There might exist different buildings with different value
yeas and different types of tax units (small house unit, apartment building unit, industrial unit and special unit) on one property. The tax  for which the Lessee shall pay compensation  shall only pertain to the building where the
premises are contained. Building normally refers to independent structure. The required data can be found in the information on decision regarding general property tax that the taxation authorities have handed over to the property owner. A property
owner, who has problems calculating the share of the Lessee, should contact his property federation for assistance.

Enter the share of
the Lessee!

4.

The clause
contains two alternatives. In the first alternative the compensation for the tax is payable as a surcharge beside the rent indicated in the Agreement. If the tax disappears, the surcharge disappears automatically. The second alternative
requires the Parties to agree on a certain rent wherein among other the compensation for the tax applicable at the time. The Lessee shall nevertheless pay for the increased expenses if the tax were to increase, regardless of the reason (for example
increased tax rate, increased tax value etc.). If the tax were to disappear, the rent returns to its original amount, i.e. the rent agreed upon (which includes compensation for the tax that was applicable at the beginning, and has now ceased).
