You're allowed to go 3 years on this but in order to do it you have to bump the yearly value to the minimum for 3 years. This means you'll pay $2m per year for 3 years, a total contract of $6m. Here's a breakdown of all your contract options:
Contract options:
1 year) $2m (2014-2015)
2 years) $1m (2015-2016)
3 years) $2m (2016-2017)
4 years) $3.5m (2017-2018)
5 years) $5.0m (2018-2019)
Here's the rule that governs this:
Contract Limits
Except for any contract inherited in 2011, all contracts must be no longer than five years. Also, for a given salary, all contracts have term limits (max years contract can be per the yearly salary) as provided below.

$5m+ - 5 years (the overall limit)
$3.5 to $4.9m - 4 years
