Here is all I have found for the moment but I wonder why the design life has been reduced from 12 years to 10 ?

Itar-Tass Wednesday 4th February, 2015
Russia's new-generation satellite to be launched from Plesetsk Feb 2015 -- Defense Ministry MOSCOW, February 4. /TASS/. A yet-to-be identified glitch has upset the operation of Russia's telecommunications satellite Express-AM33 on Wednesday, a source in the space rocket industry has told TASS, adding that specialists are currently trying to determine the causes.
Express-AM33 was put in orbit in January 2008 and commissioned in 2008.
According to information available from open sources, the satellite is a joint product of the Reshetnev Company "Information Satellite Systems" and Thales Alenia Space, built under a contract with the federal state unitarian enterprise Satellite Communications.

2008 Jan. 28: Russia launched an Express-series communications satellite in the pre-dawn hours of Monday. A Proton-M rocket equipped witha Briz-M upper stage lifted off on Jan. 28, 2008, at 3:18:00 Moscow Time from Site 200 at the Baikonur Cosmodrome. It carried the Ekspress-AM33 satellite toward a geostationary orbit. The spacecraft was developed by NPO PM of Zheleznogorsk for Russia's Satellite Communications Company, RSCC.
The Russian space agency, Roskosmos, reported that the Briz-M upper stage and its payload successfully separated from the rocket and continued their path toward their final orbit. The 2,600-kilogram Express-AM33 satellite was to be placed at 96.5 degrees East longitude above the Equator, where it was expected to function for 12 years. The launch of Express-AM33 was previously expected in September 2007.
