Item 9A. Controls and Procedures.  Conclusions of Management Regarding Effectiveness of Disclosure Controls and Procedures.  Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rule 15d-15(e) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that there was a material weakness affecting our internal control over financial reporting and, as a result of this weakness, our disclosure controls and procedures were not effective as of December 31, 2009.  Managements Report on Internal Control over Financial Reporting.  The Companys management is responsible for establishing and maintaining adequate internal control over financial reporting for the company. The Companys internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; providing reasonable assurance that receipts and expenditures of company assets are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected.  As of December 31, 2009 management conducted an assessment of the effectiveness of ESTs internal control over financial reporting based on the criteria for effective internal control over financial reporting established in Internal Control  Integrated Framework, issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission.

Management, under the supervision and with the participation of the Companys Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of the Companys internal control over financial reporting as of December 31, 2009 and concluded that it is ineffective in assuring that the financial reports of the Company are free from material errors or misstatements.

 The material weakness is as follows:  We did not maintain effective controls to ensure appropriate segregation of duties as the

same officer and employee was responsible

 for the initiating and recording of transactions, thereby creating segregation of duties weaknesses. Due to the (1) significance of segregation of duties to the preparation of reliable financial statements, (2) the significance of potential misstatement that could have resulted due to the deficient controls and (3) the absence of sufficient other mitigating controls, we determined that this control deficiency resulted in more than a remote likelihood that a material misstatement or lack of disclosure within the annual or interim financial statements will not be prevented or detected.  1    Managements Remediation Initiatives  Management has evaluated and continues to evaluate, avenues for mitigating our internal controls weaknesses, but mitigating controls that are practical and cost effective have not be found based on the size and structure of our organization.  Taking into account our reduced sales revenues during 2009, and continued uncertainty posed by the current United States economic downturn, management does not foresee implementing a cost effective method of mitigating our internal controls weaknesses in the near term.   Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.  These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake.  The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks.   Changes in internal control over financial reporting.  During the quarter ended December 31, 2009, there were no changes in the Companys internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.  2    SIGNATURES  In accordance with Section 13 or 15(d) of the Exchange Act, the Registrant has caused this Report to be signed on its behalf by the undersigned, thereunto duly authorized.
