401K PLAN INFORMATION:

Remedial Construction Services, L.P. (the “Company”) currently sponsors the Remedial Construction Services, L.P. 401(k) Plan (the

“Plan”) for the benefit of its employees. The Plan provider, Transamerica Retirement Solutions, has over 70 years of experience in the

business, and is ranked among the nation’s top providers.

By participating in this retirement Plan, you may enjoy immediate and future federal income tax savings, as all contributions taken out

of your pay toward this plan are not subject to federal income tax at the time of payroll deduction. This means you save on your

payroll taxes immediately, and your contributions, as well as earnings, can grow substantially over time. Your account will be subject

to federal income tax only when funds are withdrawn from the Plan.

AUTOMATIC PLAN ENROLLMENT PROVISION

The Company is helping to make savings for retirement under the Plan easier by offering Automatic Plan Enrollment. The Plan uses

a “negative enrollment process” under which, upon meeting the Plan eligibility requirements listed below, 2% of your compensation

will be automatically contributed to your 401k account each pay period unless you either:

(1) Opt-out of the automatic enrollment provision by signing in the Opt-Out Election box below, or

(2) Select a different contribution percentage/flat dollar amount by accessing your personal account on the Transamerica

Retirement Solutions website prior to your eligibility date.

All automatic enrollments will be invested in the Vanguard Target Retirement portfolio fund closest to the employee’s 65 th birthday,

unless you elect a different investment direction.

ELIGIBILITY Eligibility to participate in the Company’s 401(k) plan is effective after you have met the following requirements:

You have attained age 18,

You have completed 90 days of service, and

You are not a union employee, non-resident alien employee or employee from a stock acquisition or merger

Rehired employees who have attained the above eligibility during a prior tenure with the Company will begin

Automatic Enrollment contributions immediately upon rehire, unless a signed Opt-Out Election Notice is submitted

during the current rehire process (Opt Out notices signed during a prior tenure will not be applicable).

CONTRIBUTION LIMITS AND COMPANY MATCH

The 2016 IRS 401(k) elective Contribution Limit: $18,000

The 2016 additional Catch up contribution for employees 50 years of age or over: $ 6,000

The Company currently makes a match of 50% of the employee’s contributions, up to a maximum employee contribution of 6% of

pay (3% effective). This match is funded weekly at the same time as your contributions are made. An additional match may be

awarded at the end of each year based on company performance. These Company matches are discretionary, meaning that they could

each be changed or stopped at any time upon decision of the board.

CONTRIBUTION AND INVESTMENT CHANGES As an eligible participant, you may change your contribution amounts or stop deferrals into the Plan at any time by accessing your

online account at www.ta-retirement.com, or by calling Transamerica Employee Solutions Desk (800-401-8726). Contribution

investment allocations at any time by contacting Transamerica by phone or online. Fund allocation changes are effective immediately.
