The new CBA has added a 4th tender amount to the old scheme that had the high (match or 1st and 3rd compensation), middle (match or 1st round compensation) and low (match and receive a pick equal to where the lost player was drafted) tenders. Now they have added a 4th tender that is a match or get a 2nd round pick.

For 2007, the tender amounts are:

1st and 3rd: $2.35M
1st: $1.85M
2nd: $1.3M
low tender: $850K
