Subsidiaries

Shank Services

In February 2005 the Company purchased substantially all of the assets and business operations of Shank C&E Investments, L.L.C. ("Shank Services") a Houston, Texas based provider of commercial mobile and bulk fueling services, petroleum lubricants packaging and distribution and heavy haul transportation services.

The Shank Services acquisition significantly extended our presence in the major Texas markets of Houston, Dallas/Fort Worth, Austin and San Antonio and provides a platform for further growth in the Southwest.  This acquisition allowed us to enhance our product and service offerings by expanding into the sale and distribution of lubricants and related petroleum products.  It also increased our related bulk commercial operations and emergency generator fueling services.  Since Shank Services was experienced in delivering emergency response fueling services in disaster relief situations, the acquisition also increased our capability to provide this service regionally and nationally.

In October 2005, the Company acquired H &W Petroleum Company, Inc. (“H & W”), a Houston, Texas based marketer and distributor of lubricants, commercial fuels and petroleum products and Harkrider Distributing Company, Incorporated (“Harkrider”), a Houston based marketer and distributor of dry cleaning solvents, chemicals and petroleum products, which was related to H & W through some common shareholder ownership.

The H & W acquisition has enabled us to expand our services of marketing and distributing branded and non-branded lubricants, fuels and other petroleum products in Texas, together with adding the marketing and distributing dry cleaning solvents and chemicals.

H & W provides service to the Houston, Beaumont, Dallas/Fort Worth, Freeport, Longview, Lufkin, San Antonio, Waco/Temple and Waxahachie markets in Texas, and the Baton Rouge/New Orleans market in Louisiana.
