ADA-ES Retirement Plan

The ADA-Es Retirement Plan is composed of three elements: 401(k) Employee Contributions, 401(k) ADA-ES Matching Contributions, and Profit Sharing.

401(k) – Elective Contributions

Full-time employees may begin contributing to their 401(k) Employee Contributions account immediately upon employment. An employee can elect to defer up to $14,000 of salary (for 2005) into the account (or up to the IRS limit for such contributions). The contribution is made on a “before-tax” basis in order to reduce the employee’s taxable compensation. These funds are fully vested at all times. If you are over age 50, see the Human Resources Manager for the ability to make “catch-up” contributions.

401(k) – ADA-ES Matching Contributions

ADA-ES will contribute 100% of an employee’s 401(k) contribution up to a maximum of 5% of salary into the 401(k) Employers Contribution account. Employees are eligible to begin receiving these contributions following the 1-year anniversary of employment. Funds in this account are vested based on the 2-20 rule, where employees are vested at 20% after 2 years of service, 40% after 3 years, 60% after 4 years, 80% after 5 years, and 100% after 6 years. These contributions are normally made in cash.

Profit Sharing

See the Profit Sharing Plan for more details.

Morgan Stanley establishes and administers the ADA-ES Retirement Plan accounts for employees. Employees work directly with Morgan Stanley to direct the investment of funds.

Profit Sharing Plan

Eligible employees may earn additional cash, stock or 401K contributions at the end of each calendar year. Each employee’s share is derived as a calculation based on ADA-ES net earnings before taxes. 50% of the earned allotment is applied to the ADA-ES Retirement Plan, 20% is awarded as a company wide distribution of cash or stock, and 30% is a cash or stock award based on employee performance.

Automatic Payroll Deposit

ADA-ES will automatically deposit an employee’s pay, or portions of pay to employee-directed accounts (savings accounts, checking accounts, credit union, etc.). The receiving institution must have a direct-deposit option for account holders.

Credit Union

The company is a member of the Bellco Credit Union. Employees may elect to become a member at their discretion.

Supplemental Insurance

Employees may elect to purchase supplemental insurance products through AFLAC at discounted rates. Payment to the program is made through bi-weekly payroll deduction. Some of the products offered include:

Other plans offered by AFLAC are available to employees. If interested in more information, contact the Human Resources Manager.

Mr. Rich Miller

4589 Lehigh Drive

Walnutport, PA 18088

Dear Rich:

ADA-ES is pleased to offer you employment as Vice President, Sales reporting to our President and Chief Executive Officer, currently Michael Durham. The bi-weekly salary for this position will be $5,000.00 (equivalent to $130,000.00 on an annualized basis). Employment will begin on November 28, 2005.

Vice President, Sales is an executive position responsible for developing and executing sales plans on existing and new ADA-ES products, personnel management and development, and managing all aspects of assigned product line and project budget and financial results. As you know, travel will be required as part of the job. This is a full-time, exempt position, and as such, the position is eligible to receive our standard benefits package.

As additional incentives, during your initial year of employment, ADA-ES is offering to match up to 5% of your base salary in contributions to an individual IRA account or other qualified pension plan. Vesting rules under the ADA-ES Retirement Plan would apply. A copy of the Summary Plan Description is attached. ADA-ES will also provide an allowance, initially in the amount of $1,000 per month towards mileage used for a personal car. Mileage in excess of this amount will be reimbursed at the government-approved rate. We would expect to review the allowance amount periodically to determine its appropriateness.

Typically, the Board of Directors offers new employees ADA-ES stock options shares related to the employee’s base salary. A request for 13,000 share options will be submitted on your behalf and will be awarded contingent upon Board approval at their next regularly scheduled meeting. Vesting of these shares typically occurs at a rate of 25% semi-annually with 100% vesting after 24 months of employment. As an executive, you will also be covered by the Company’s Executive Compensation Plan, a copy of which has been provided to you.

We recognize that by joining ADA-ES you will forego benefits that you earned through your years of employment with others and we will make an exception to our vacation policy by granting you vacation at the 13-year employee level, accruing vacation at 13-1/3 hours per month, for a full-time employee.
