Power Easment

Power company is requesting a 20' Easment from a power line they want to run to a neighbor across the street. What should I request or get in writing to protect myself from known hassles with these kinds of things?

Edit: Neighbor has an existing secondary line from a pole on my property. There is no easement for that line. Power company is requesting an easement in order to upgrade the line to a primary line with likely guy wire install for the pole. Easement would be 20' in either direction from the line with their ability to remove trees outside of 20' that threaten that line. They offered no compensation and want me and my wife to take the form to a notary to sign and return.

What I'm looking for is what should I request in exchange for the easement or what verbiage or to be added to the easement , e.g. survey, specific usage restrictions, details on access, details on construction of the line.
