The Mercer HR Services Retirement Plan (the "Plan") is a tax-qualified retirement plan. Each calendar quarter, Mercer HR Services ("Mercer HR Services" or the "Company") plans to contribute an amount to a retirement account set up for you. The amount will be based on your years of service and your eligible compensation. You then will be able to invest your account in a number of investment funds. The Plan does not accept employee contributions.

Under this Plan, you assume responsibility for investing your account and the investment choices you make. Plan participation involves investment risk. If the value of the funds in which your account is invested decreases or increases, the value of your account in the Plan will also decrease or increase.

The Plan is intended to be tax qualified under Section 401(a) of the Internal Revenue Code. Accordingly, the Company's contributions may not exceed the applicable limits set forth in the Internal Revenue Code.

This section describes the Plan provisions as of June 6, 2008, and applies if you are employed by the Company on or after June 6, 2008.

As used throughout this document, "employee," "you" and "your" always mean a U.S. salaried employee of Mercer HR Services. Individuals classified on payroll as hourly, who are leased employees, who are compensated as independent contractors, who are employed in Puerto Rico, or who are interns are not eligible to participate.
