| ·   | Contracts are predominately short-term in nature (less than six months) and revenue is recognized as costs are incurred and billed.  Revenues recognized in excess of amounts billed are recorded as an asset.  In the event interim billings exceed costs and estimated profit, the net amount of deferred revenue is shown as a current liability.  Estimated losses are recorded in full when identified. |

| ·   | The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, which results in bad debt expense.  Management determines the adequacy of this allowance by continually evaluating individual customer receivables, considering the customer's financial condition, credit history and current economic conditions.  If the financial condition of customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. |

| ·   | The Company maintains a valuation allowance for deferred tax assets to reduce these assets to their realizable amounts.  Recognition of these amounts and the adjustment of the corresponding allowance is dependent on the generation of taxable income in current and future years.  As circumstances change with respect to management’s expectations of future taxable income, the valuation allowance is adjusted. |

| (a)   | Disclosure Controls and Procedures. |
|-----------------|-------------------------------------|

| During the quarter ended June 30, 2010, the Company enacted changes to internal controls over financial reporting based on a material weakness identified for the year ended December 31, 2009 regarding unearned revenue and financial reporting.  The unearned revenue review process now includes a more in-depth cost and standard gross margin analysis, review with field personnel, and a comparison to subsequent billing by job.  Additionally, financial reporting controls have been enhanced to include an in-depth review of collectability by customer with collection and sales personnel to ensure any customer agreements made have been properly disclosed. |
