Adidas will continue to be the supplier of the official match balls  for all of Europe's leading tournaments and will also continue to equip staff, officials, referees, volunteers and ballboys for all  the national team competitions in Europe during the period.

Euro 2012 is to be held in Poland and Ukraine and the 2016 event is due to be awarded later this year.

Herbert Hainer, the chief executive and  chairman of Adidas said: "Adidas has been a clear winner of UEFA Euro 2008 and we are looking forward to continuing this success story with the long-term extension of our contract with UEFA for one of the biggest sports events in the world.

"The history of  adidas as a strong  partner of UEFA goes back more than three decades and will continue to be an important pillar in our strategy to expand our global market leadership in football in the future."
 

David Taylor, the UEFA general secretary, said: "It is  significant that  the first  UEFA Euro 2012 partnership agreement we are able to announce is with adidas.

"UEFA is all  about football and  the beautiful  game is also at the core of Adidas' business.

"They are the leading football brand in the sporting goods category, and beyond their promotional activities, they will also  be providing top-level support  to all our events and courses,  through the provision of official  match balls and other sporting goods and apparel.
 

"UEFA Euro is a hugely valuable and attractive event for sponsors  to be associated with, and, with further agreements due to be announced before the end of the year, we are confident of completing the global
sponsorship programme by the summer of 2010.

In addition to Euro 2012 and Euro 2016, the UEFA EUROTOP agreement also includes a relationship with UEFA over all the national team competitions, including major tournaments such as the UEFA European Under-21 Championship in 2011, 2013, 2015 and 2017 and the UEFA European  Women's Championship 2013 and 2017, and numerous education courses for coaches and referees through to the end  of 2017.
 

Adidas has supplied the official match balls to all major UEFA tournaments since 1972, and has also been the official supplier of the match ball for all UEFA Champions League games since 2006. 

The adidas Finale ball has been used for the UEFA Champions League final since the 2000/2001  season.

Starting  from this season, the UEFA Europa League and the UEFA Super Cup are  played with Adidas
balls as well.

Since 2008, adidas has also been the official supplier of the match ball for the African Cup of Nations organised by the Confederation Africaine de Football (CAF).

Adidas are also a Tier One sponsor of the London 2012 Olympics and Paralympics.
