Howe told BBC Radio Northampton: "I don't intend to go back to Peterborough. Hopefully something can get sorted here or elsewhere.
"My family lives 10 minutes away and I've enjoyed my time here. But I don't know what's going to happen."
Howe was a prolific scorer at Bedford Town and Kettering Town before joining Peterborough United where he was used largely as a substitute in the 2007/08 season, scoring once in 17 appearances.
He has had loan spells at Rochdale, Morecambe, Lincoln City and Gillingham.
