Ulster have announced that Stephen Ferris and Declan Fitzpatrick have agreed new deals with the province and Irish Rugby Football Union.
Prop Fitzpatrick has inked a two-year deal that will keep him at Ulster until at least mid-2016 while blindside flanker Ferris pens a short-term deal.
Fitzpatrick, who is in the international frame, has been capped seven times for Ireland and made his Ulster debut against Biarritz back in 2006.
"I am delighted to be staying at Ulster for a further two years," he told Ulster's official website.
"Both my family and I love living in Belfast so it is great to have our long-term future sorted out. I hope to make a significant contribution in the coming seasons and my aim next year is to nail down a starting place."
Ulster's Director of Rugby, David Humphreys, added: "Declan is a hugely important member of our squad and has proved at both Provincial and International level that he is a top performer."
"His opportunities have been restricted in recent seasons due to injury, so it is great to see him fully fit and playing some of the best rugby of his career.
"I am pleased that he has committed to Ulster for a further two years."
Ferris' deal meanwhile allows him to continue his rehabilitation from the ankle injury that he sustained against Edinburgh in November 2012.
"Stephen has shown remarkable drive and determination over the past year as he has worked to overcome the injury that has kept him out for so long," added Humphreys.
"We are committed to helping him in every way possible and his new contract extension will mean that he will continue to have the best medical, physiotherapy and strength and conditioning teams around him, to help his recovery."
