A Nathan Jarman double secured a point for Grimsby at home to Exeter.
Marcus Stewart put the visitors ahead with a fine finish following a quick free kick on eight minutes, but Jarman equalised on the stroke of half time.
The 22-year-old put Grimsby ahead nine minutes into the second half only for substitute Ryan Harley to claim a point in the 77th minute.
Grimsby could have had a third but Jean-Paul Kalala saw his effort rebound off the bar.
