The relegated Raydale Park outfit remain in administration amid continuing fears they could go out of business when the Clydesdale Bank Premier League season ends.
An unidentified American group have been suggested as possible candidates in recent weeks.
Although Wadsworth was unable to specify the credentials of each party, he feels the club may be edging towards a brighter future.
He said: "In terms of people interested, I believe there are four interested parties.
"Who they are, I honestly couldn't tell you.
"We obviously hope one of those parties is capable of taking the club over when the right time comes at the end of the season to give the club the opportunity to carry on.
"It's certainly a better situation than it's been at other times. We've been really down on our heels, in desperate straits really, believing that the club could close and finish at any time.
"Suffice to say, a lot of people have suffered, lost their jobs, like previous employees and players.
"We're okay because we're training and working, that's what we enjoy, but a lot of people have suffered and will all suffer, in a sense, because probably most of us will not be at the club from the end of the season onwards."
