Newbie with lease offer

Hello. Some family members and I inherited mineral rights in Greene County, PA. We were not aware of this until we were contacted by EQT with lease offers. Since none of us are familiar with this topic, I was hoping I could get some quick advice here. I did contact some lawyers in PA, but both said it wasn’t worth the money to get them involved because my share is so small (it could cost me more in legal fees than I would make from the lease). Here are the details of the lease: -5 years -38 acres -My share is 2.5% -$3500 lease signing bonus -18% cost-free royalty (no post-production deductions)

Does this look reasonable? I just want to make sure we are getting a fair deal. Thank you!
