England fly-half Danny Cipriani is among 13 players who have committed their future to Wasps for at least one more year.
The news comes just two weeks after the confirmation that England trio James Haskell, Riki Flutey and Tom Palmer are all joining French sides at the end of the season.
Staying put along with Cipriani are fellow internationals Phil Vickery, Tom Rees, Tim Payne, Dave Walder, Simon Shaw and Mark van Gisbergen, plus Dominic Waldouck, Danny Birkett, Tom French, John Hart and academy pair Joe Simpson and James Honeyben.
Director of rugby Ian McGeechan said: "We are delighted with the volume of players committing to the club for next season and for those to come.
"This is a great show of intent from the players and our board as we see a mixture of experienced and international calibre players combine with up-and-coming names.
"All of these play a pivotal role in our campaign both now and in the future and are core to the continuing development of the team and our rugby."
Cipriani is one of those who have signed just a one-year deal - Vickery, Rees and Shaw are for two years and prop Payne for three - but executive director Mark Rigsby commented: "We're absolutely delighted to be making this announcement.
"We hope today goes an awful long way to putting an end to the speculation."
No figures have been revealed, but flanker Haskell was reported to have been offered an annual wage of around £300,000 by Stade Francais.
That is a figure way out of the range of Guinness Premiership sides, who recently opted to freeze their player budgets at £4million for the next two seasons.
Cipriani, axed by England after the November defeats to Australia and South Africa, made it clear in December that he wanted to stay put.
"I'd like to stay at Wasps and have my future here. I've just got to know about the players who are going to stay around as well.
"You want to make sure you have all the young players and you have all the talented players coming through together and staying on.
"Wasps is such a great club. It is a unique place with the values to win.
"There are some of the best coaches in the world here (Ian McGeechan has Wales coach Shaun Edwards assisting him) and their winning mentality rubs off on the younger players.
"Winning trophies is what it is all about. It is the best feeling."
Wales' acting head coach Rob Howley has given Sam Davies and Rory Thornton a boost ahead of the RBS 6 Nations by naming the uncapped Ospreys duo in his largely experienced squad for the Autumn Internationals.
