A fundamental flaw of the LOI, lies in what Vasilios J. Kalogredis, a Wayne, Pennsylvania attorney, calls "the uncertainty and potential risk of any such undertaking." Kalogredisis, a business contract law expert, explains it this way:
"Buyer who is serious, ready and able to purchase [crude oil], will sign [an] LOI and all the necessary documents that protect the rights of the Brokers and proceed. There is nothing to lose in signing those documents. This is how it is usually done and this is how it should be."
