Umps had said their salaries previously averaged $15,000 at Triple-A, $12,000 at Double-A, $10,000 in full-season A-ball and $5,500 in rookie leagues.
As part of the new deal, per diems rise $3 to $28 at Triple-A, $25 at Double-A and $23 at Class A. They will rise gradually to $40 at Triple-A in 2011, $35 at Double-A and $30 at Class A.
Umpires will return to work by June 12. They had been on strike since minor league seasons began April 6.
"Our goal from the beginning of these negotiations was to obtain a fair contract," Andy Roberts, president of the Association of Minor League Umpires, said in a statement. "It has been a tough struggle, but an important one for our membership. Now it's time to get back on the field. The umpires are ready to work, and we look forward to the rest of the season."
Umps and the Professional Baseball Umpire Corporation agreed to a contract April 27, but umpires rejected that agreement by a 2-1 margin on May 1. The sides resumed talks last Wednesday with the assistance of a federal mediator.
"Late Friday, the AMLU made a proposal to settle the strike that PBUC agreed was acceptable," management lawyer George Yund said in an e-mail Tuesday.
