A THIRD company, NEC, is reviewing its St Kilda sponsorship.

Bill Express has already quit as a co-naming rights sponsor of the club, and Vodafone is considering switching allegiances to Carlton.

NEC is one of two second-tier Leadership Group sponsors of St Kilda, along with The Age.

"We will be reviewing that contract over the next few weeks," an NEC spokesman said. "We review all sponsorship deals when they are due to expire."

St Kilda chief executive Archie Fraser confirmed that NEC was assessing its options for 2008.

"I am aware of that, but we are hopeful they will still (be) on board for next year," he said.
