Skipper Joseph Mills says the three points achieved against Leyton Orient last week could be a big result in the context of the season.
A Cobblers side missing Jon Guthrie, Shaun McWilliams and, for most of the game, Kion Etete, dug deep and ended Orient's eleven match unbeaten run with a 1-0 victory.
"We had a few players out last week and it felt a really big three points," said Mills.
"We overcame a really good side who are tough to beat. I thought Max Dyche did really well, he has been in and around the squad and he is a confident lad who knows what is required. He knows the level the lads have been performing at and I have seen the level of training has been brilliant in the last few weeks. Nicke Kabamba also did well in a tough role up front and a few of the lads did what they had to do in different roles and that is the spirit we have.
"The conditions were tough against Leyton Orient and on days like that you just have to grind things out. It is about finding a way to win, whether that be through great football or by grit and desire, you do what you have to do based on the circumstances you face. Orient are a very well organised side but we defended really well and took our chance at the right time.
"We are delighted with where we are in the league. There is a good spirit in the dressing room and that helps. We have some decent players too and while there is a long way to go and things can change quickly, we are pleased. There are some strong teams in this division but we can only deal with ourselves. We can rest a few legs this weekend and we head in to December well placed.
"Exeter will be a good game. They are always strong at this level and have made the play offs regularly over the last few years. There will be a good atmosphere there and we know what we are in for and I know the lads will be ready."
