Glasgow Warriors flankers Rob Harley and Tyrone Holmes have both agreed new deals to prolong their stay at Scotstoun.
The back-row pair have penned extended two-year contracts, which will keep them at the club until at least May 2016.
Harley joined Glasgow in 2010 and has made 93 appearances for the RaboDirect Pro12 side.
The 23-year-old has become a regular in the Warriors pack and won his first of five Scotland caps on the 2012 summer tour to the South Seas, scoring a try on his debut against Samoa.
Harley said: "I've really developed as a player over the last four years, getting regular game time at the Warriors and playing for Scotland.
"I feel like this is the perfect place for me to continue my development, working with a great group of players and coaches."
Holmes joined the club last summer on a one-year deal and has featured regularly this season, making 17 appearances.
The 28-year-old said: "It was a great decision to come to Glasgow in the summer and I'm delighted to be staying for another two years.
"My father was born in Peebles and he is so proud of what I've achieved in Scotland this season."
Warriors head coach Gregor Townsend said: "It was really important for us to get Rob and Tyrone re-signed as the back-row is a very competitive area for most teams.
"Rob is a very consistent player and is extremely hard working. He is always prepared to put his body on the line in training and in games.
"Tyrone has been great for us since joining in the summer. He's really given us competition at openside and has pushed Chris Fusaro to playing at his best.
"As we approach the most important part of our season, it is a boost to have secured Rob and Tyrone for the next two seasons."
Meanwhile, the club have signed scrum-half Murray McConnell on a one-year contract from next season.
The 21-year-old development player has impressed for Ayr in the RBS Premiership this season and was included on the bench for Glasgow in their win over Connacht at Scotstoun in February.
