PART I

ITEM 1. BUSINESS

The Company was incorporated as Aspen Exploration Corporation under the laws of the State of Delaware on February 28, 1980 for the primary purpose of acquiring, exploring and developing oil and natural gas and other mineral properties. During the first half of 2009, Aspen disposed of its oil and natural gas producing assets and as a result was no longer engaged in active business operations. On June 24, 2010, Aspen entered into an Agreement and Plan of Merger and Reorganization with Dillco Fluid Service, Inc. (“Dillco”) which set forth the terms by which Dillco became a wholly owned subsidiary of Aspen on July 27, 2010 (the “Merger Transaction”).

On December 30, 2010, Aspen changed its name to “Enservco Corporation.” As such, throughout this report the terms the “Company” and/or “Enservco” are intended to refer to the Company on a post Merger Transaction basis and as a whole, with respect to both historical and forward looking contexts. As a result of the Merger Transaction, the Company’s fiscal year was modified to be the calendar year as described below.

The Company’s executive (or corporate) offices are located at 501 South Cherry St., Ste. 320, Denver, CO 80246. Our telephone number is (303) 333-3678, and our facsimile number is (720) 974-3417. Our website is www.enservco.com.

Corporate Structure

Immediately prior to closing the Merger Transaction and as a result of an internal reorganization that commenced in 2009, Dillco’s assets and the ownership interests of its subsidiaries were held and controlled primarily through a holding company, Enservco LLC (“LLC”). Certain of these reorganizational transactions are further described under Item 13 of this Annual Report.

On July 26, 2010, immediately prior to completion of the Merger Transaction, Dillco merged into LLC, with Dillco being the surviving entity in that transaction. Prior to that transaction, the LLC served as a holding company for Dillco, Heat Waves Hot Oil Express LLC (“Heat Waves”), and other entities that owned assets utilized by the Company in its business operations.

Immediately prior to the completion of the Merger Transaction, Dillco had two owners, Michael D. Herman (90%) and Rick D. Kasch (10%). Mr. Herman has been a Manager, Chairman, Chief Executive Officer, and control person of the LLC, Dillco, Heat Waves and the other Dillco subsidiaries since the time of their formation and/or acquisition by the LLC. Mr. Kasch has served as the Chief Financial Officer and a Manager for these same entities since the time of their formation and/or acquisition. Messrs. Herman and Kasch became significant shareholders of the Company as a result of the Merger Transaction.

The Company’s business operations are conducted primarily through Dillco and Heat Waves (100% owned by Dillco). The below table provides an overview of the Company’s current subsidiaries and their activities.

Overview of Business Operations

As described above, Enservco primarily conducts its business operations through two subsidiaries, Dillco and Heat Waves, which provide oil field services to the domestic onshore oil and natural gas industry. These services include pressure testing, hot oiling, acidizing, frac heating, freshwater and saltwater hauling, fluid disposal, frac tank rental, well site construction and other general oil field services. As described in the table above, certain assets utilized by Dillco and Heat Waves in their business operations are owned by other subsidiary entities.
