Downstream market sales question

We received a lease to review. It purports to be a no deduction on royalties lease with the following exception. I have not come across these terms before and was wondering if anybody could explain the clause and the possible costs incurred.

Thanks.

....except for, if applicable, Lessor’s proportionate share of downstream transportation
expenses for any sales of Leased Products made at a distant sales point in a
downstream market (e.g., New York City Gate) after delivery to the point of
sale at the interconnect with the interstate pipeline, accompanied with
supporting documentation as to the cost basis of such downstream market sales;

Strike the clause. You should not be responsible for transport of the product. You want pay at the wellhead.

If they work a deal with the local interstae pipeline to not pay you until it gets to a major hub, you would be paying all transportation costs. Strike it. They may be inserting this to try to deduct the cost of compressing gas into liquid for purposes of exporting it.

Thanks. That is the info I wanted. Now, waiting on a second lease.
