You definitely need more details before you decide whether to go further. Some things to consider: What type of gallery is it? Commercial, co-op, vanity? Are they looking for new artists to represent or is this for a one-time only exhibition of works from many new artists? Does the gallery's style match yours? Ask to see a copy of the contract in advance.
Be aware that commercial gallery commissions can be as high as 60% of the sales price and their contracts are fairly restrictive as far as sales rights. In other words, even if you sell a hanging piece to your neighbor while it's on exhibit, the gallery gets their commission. They do work very hard to market the artists they represent and the works they have however, and gallery representation is considered a major career step for many serious artists. Good luck to you!
