Remember, I cannot read your documents on this forum, so I cannot give you a firm answer on this question (I just want to make sure there is no misunderstanding).
The proposed business
arrangement appears to be overly complex. If the LLP is designed to make arrangements for the delivery of cattle, and it is separate and apart from the packing plant, there does not seem to be any issue with the current management of the plant. The only issue that appears from a pure economics study is that without the plant operating it will be more costly for the LLP to deliver cattle to another processor.
The right to deliver, and the grid and agreement appear to be rights owned by the contemplated LLP. However, from your post I am not certain that this is the case. If this is not the case, it would appear that the LLP owns nothing, and merely organizes cattle.
There does not appear from what you have described anything that would require new plant owners or operators to honor a grid agreement absent express contract
between the plant and the coop. If the LLP has a procurement contract with the Plant for a period of time into the future, that could be part of a plant purchase agreement and be binding on future plant owners.
This all depends on the language in the contract.
If the grid agreement and the easements are the important issues for you in this transaction - look to make sure that they are spelled out clearly and in plain language in (1) the LLP partnership agreement, (2) a contract between the LLP and the processing plant, and (3) any contracts binding landowners or necessary partys to the grid or easements with the LLP.
If you are giving away any easements on your own property, I would advise getting an attorney to at least take a look at the document to make sure it is not overreaching and can be terminated appropriately.
