DEREK Adams is to remain at Home Park until 2020.
On the eve of the new Sky Bet League Two season, the Argyle manager has agreed a new four-year deal which replaces his current contract that was scheduled to expire at the end of the upcoming 2016-17 campaign.
The extension of Derek's tenure comes just over a year after he joined the Pilgrims in succession to John Sheridan.
In his debut season, the 41-year-old Scot steered the Pilgrims to the Sky Bet League Two Play-off Final, taking the club to Wembley for only the second time in Argyle's history.
He has rebuilt the squad this summer in preparation for another promotion push, which begins with Saturday's visit of Luton Town to Home Park.
Argyle Chairman James Brent said: "I am delighted that the Board and Derek have agreed an extension to his contract to 2020.
"Derek has already made a major contribution to Plymouth Argyle and the Board believes he has much more to offer.
"Much of what football clubs do is focused on the current season and yet, to achieve sustainable success, we believe that plans need to be implemented for the medium-term, as well.
"Derek's contract extension to 2020 – when we and the rest of Plymouth will be celebrating the 400th anniversary of the sailing of the Mayflower and the founding of modern America – will help enhance the club's focus on the medium and longer terms. ”
