INDEX CLAUSE FO R NO N-RES IDENTIA L PREM IS ES Pag e 2 (2) 2 Appendix no: Instructions for indexing of rent for non-residential premises Base rent W hether or not all, or a certain part, of the rent stated in the agreement and the f ixed rental supplements are to constitute the basic rent is a matter of negotiation and can depend on the terms of the lease otherwise (such as the amount of rent payable and what other obligations are incumbent upon the tenant). Base figure The index level f or the month of October to which the base rent is deemed to be adjusted constitutes the base f igure provided nothing else is stated by way of a statement of a year (see the provisions on page 1). Comparison between the index levels shall take place a soon as the index f or October becomes known. During recent years, the October index has become known in the middle of N ovember. Calculation of index supplement 1) Calculate the dif f erence between the relevant October index and the base f igure. 2) If the dif f erence is positive, divide the calculated dif f erence by the base f igure. 3) The size of the supplement is calculated by multiplying this quotient by the base rent. Example Calculation of index supplement f or 2008 The base rent is assumed to be SEK 100 000/year and is adjusted to the consumer price index (CPI) f or October 2005, which is 282.4 (base f igure). The October index f or 2007 is 293.85. 1. Calculate the dif f erence between the index 293.85 and 282.4 The dif f erence is positive and amounts to 11.45. 2. Divide 11.45 by 282.4 and multiply the quotient (without rounding of f ) by the base rent of SEK 100 000. The result is SEK 4 054.53 and constitutes the index supplement f or 2008 in accordance with the clause. Alternative: If the CPI f or October 2007 had instead been lower than the base f igure 282.4 e.g. 282.0, the dif f erence between 282.0 and the base level 282.4 would have been negative. N o index supplement would then be payable. The rent stated in the lease agreement and the f ixed rental supplements would apply.

PROPERTY TAX CLAUSE FO R NO N-RES IDENTIA L PREM IS ES Sid 2 (2) 3 Appendix no.: Instructions - Property tax clause for non-residential premises 1. The clause was f ormulated in June 1995, i.e. bef ore the time (normally the 1st of January 1996) f rom which property tax f or premises applies. Theref ore the clause has a wording which means that it can be incorporated in agreements that have been made bef ore the tax is payable, as well as in agreements where the tax is actually payable. 2. The reimbursement shall compensate f or the increased costs of administration irrespective of who is liable f or the tax. A property owner/landlord is liable f or tax. According to previous regulations if the property owner/landlord was a trading partnership the owners/shareholders were liable f or tax. The supplement was nevertheless to be paid to the Landlord as a matter of course. Af ter the 1st of January 1997 trading partnerships as such (and not the individual owners/shareholders) are liable f or property tax. 3. According to section 19 of the R ent Act the rent must – with some exceptions – be determined in the Lease Agreement. If the rental period is f ixed, and is f or at least three years, certain additional exceptions apply in that the rent shall be payable with such sums which are determined according to "dif f erent method of calculation" e.g. indexation. This also means that the rental period has to be f ixed and be at least three years to enable the Landlord to obtain reimbursement f or property tax in sums that can vary as the tax changes. F urthermore the method of calculation must be shown in the Lease Agreement. The clause theref ore presumes that the parties state what share of the tax the tenant shall provide reimbursement f or. According to the regulations that apply when this clause is f ormulated the tax is comprised of a certain percentage of the assessed value of the premises (both grounds and buildings). This inf ormation is to be f ound in the tax statement. The tenant’s share of the tax f or the premises can be determined by the relationship which the extent of that area leased by the tenant bears to the total lettable premises in the property or as a relationship between the tenant’s rent and the total of the rents f or premises in the property. It is a matter f or negotiation which method of calculation the parties choose. Other methods of calculation can be used. F or the sake of simplicity, however, the tenant’s share should be unchanged during the rental period, and thereby independent of among other things, how the tax in the f uture might be calculated and possible changes in the rental market. It is theref ore appropriate to show in the designated space how the premises share has been calculated. Should details in respect of this not be completed this does not mean that the agreement becomes invalid. A property can comprise of a variety of dif f erent buildings with dif f erent value years and dif f erent taxation categories (small dwelling houses, apartment blocks, industrial units and special units). The tax – that the tenant is due to pay reimbursement f or – shall only relate to the building in which the premises are located. A building is normally def ined as a f ree standing self -contained building. R elevant inf ormation can be ascertained f rom inf ormation regarding decisions ref erring to general property taxation that the tax authorities have advised the property owner. Any property owner who has a problem in ascertaining the tenant’s share should contact their property owners association f or assistance. Com p lete the tena nt´s sha r e! 4. The clause contains two alternatives. In the f irst the reimbursement f or the tax is payable as a supplement "alongside" the rent agreed in the Lease Agreement. If the tax disappears so does the supplement. The other alternative presumes that the parties agree a specif ic rent which includes, among other things, reimbursement f or the then applicable tax. Should the tax be increased irrespective of the cause (f or example increase in tax rates, increased assessed value etc) the tenant shall nevertheless tender reimbursement f or the increased cost. Should the tax disappear the rent reverts to the original sum, i.e. the agreed rent (which includes reimbursement f or the tax applicable at inception which has been discontinued).
