9. Concentration of Risk

Key Supplier. GEL is the exclusive supplier of crude oil to the Nixon Facility pursuant to the Crude Supply Agreement, which expires on August 12, 2014.

Significant Customers. Customers for our refined petroleum products include distributors, wholesalers and refineries primarily in the lower portion of the Texas Triangle (the Houston - San Antonio - Dallas/Fort Worth area). We have bulk term contracts in place with most of our customers. Many of these arrangements are subject to periodic renegotiation, which could result in us receiving higher or lower relative prices for our refined petroleum products. For the twelve months ended December 31, 2012, our four largest customers accounted for approximately 84% of our refined petroleum products sales.

Sales by Product. All of our refined petroleum products were sold in the United States. The following table summarizes the percentages of all refined petroleum products sales to total sales:
