shall have a unilateral right to termination on 2020-12-31, and 2021-12-31 with a 9-month notice period each year. For this reason,
the Tenant's base rent will increase by 100 SEK/sqm which gives a new base rent of SEK 1 896 906 excluding VAT.


 


2) The Landlord will order and perform adaptation in the premises
in accordance with the attached adaptation attachment.


 


3) The Tenant must pay for the adjustment during three years

181 935 excluding VAT shall be paid. A total of SEK 2 183 233 excluding VAT. Should the Tenant exercise his right to early
termination, the Tenant will pay the remaining amount, as a one-off payment in connection with the last invoice.
