Dundee have completed the signings of former Rotherham United full-back David Worrell and David O'Brien, the winger having left Stirling Albion.
David Worrell and David O'Brien were out of contract
Worrell and O'Brien were out of contract and are the first of six summer signings planned by Dundee.
O'Brien, 23, leaves after helping Stirling win promotion to Division One.
Worrell, 29, who enjoyed two promotions with Plymouth, told Dundee's website: "We're obviously going to have a real go at winning promotion to the SPL."
In 1999, he had been signed for £50,000 by Dundee United from Blackburn Rovers.
"One of my first matches was a Dundee derby," he recalled.
"Coming from reserve team football at Blackburn to that atmosphere was a total culture shock.
"I couldn't believe the pace of the game and the passion of both sets of fans was unbelievable."
First Division Dundee have also confirmed that manager Alex Rae will receive an increased budget for next season.
But chairman Bob Brannan has stressed to the Tayside business community that further cash will have to be raised to balance the budget.
Chief executive Dave MacKinnon pointed out that the club is considering developing land for housing.
Dundee are looking at developing the Dens Park side of their stadium "with a new South Stand as part of the development".
MacKinnon has held initial discussions with a building developer.
