Is Lease offer reasonable? Section 65, Block 1, Lot 44

We’ve been offered a 3 year lease at $8,000 NMA on in Section 65, Block 1, Lot 44 W&WN RR, Loving County, TX, 2.5 Acres = $6,666 for .83 NMA. Royalty: 1/4th (25%)

Is this a reasonable offer? Is engaging an attorney worth it? Thanks for your help. Bob
