YIT Sverige AB has signed an agreement with Locum AB regarding technical

covers buildings and infrastructure within an area of approximately 390,000     
square meters.                                                                  

YIT will be providing services for heating, ventilation, cooling, control and   
regulation, high and low voltage, backup power, medical gases, sterilization    
technology, lifts, pneumatic tubes, etc. YIT also has an operations centre in   
the hospital area that is staffed around the clock and monitors all fields of   
technology in the hospital area.                                                

"Locum chose YIT due to their good evaluation ratings in, among other things,   
quality management and development, organization and competence, as well as work
with energy optimization," says Marie Boestad, property manager at Locum. "For  
Locum, it's important that the contractor focuses on high operational           
reliability so as to ensure that the highly specialized care that is provided at
the university hospital is not affected by disturbances."                       

Locum procures all property services under competitive forms in the open market.
In this way, the quality of the services are defined to comply with the needs of
Locum and health and medical care, while at the same time, cost levels are      
attained that are based on conditions in the market.                            

"Competitive procurement gives Locum continued good cost control combined with a
focus on safety and energy savings," says Marie Boestad.                        

The terms of the agreement are five years with the option of extending the      
agreement two years at a time. It will go into effect for buildings on July 1,  
2010 and on April 1, 2011 for infrastructure.                                   

Since 2002, YIT Sverige AB has had a corresponding agreement with Locum AB and  
maintained an established operational organisation with a staff of about 50 at  
the Karolinska University Hospital area in Solna.                               

"It is very satisfying to have received this vote of confidence in furthering   
the excellent results we've achieved together with Locum and health and medical 
care during the past several years," says Pierre Holman, business unit manager  
within Facilities Management at YIT Sverige AB. "It's going to be exciting to be
able to continue following developments at Karolinska University Hospital in    
Solna."
