Item 5: Fees and Compensation
Method of Compensation and Fee Schedule
 QUALIFIED PLANS
 The annual fee for services shall be calculated as an annual investment advisory fee of no
 more than 1% of the total assets under management. The annual fee is negotiable and may
 be charged as a percentage of the Included Assets or as a flat fee. Consulting fees are based
 on the scope of work and estimated hours of completion. Flat fees are based on selected
 services and will not exceed 3% of plan assets. The following items include but are not
 limited to determining flat fees:
    •     Plan size
    •     In person meetings for participants or plan sponsor
    •     Associated travel time and costs
    •     Education requirements
    •     Assumed liabilities
    •     Scope of services, for example, leading an employer through an RFP for a new
          recordkeeper or TPA, assistance with transitioning plans to the new providers, etc.

 Also, to be noted, at times fees may exceed the money market yield.
 Fees may be charged quarterly or monthly in arrears or in advance based on the assets as
 calculated by the custodian or record keeper of the Included Assets (without adjustments
 for anticipated withdrawals by Plan participants or other anticipated or scheduled
 transfers or distribution of assets). If the Qualified Plan Agreement is terminated prior to
 the end of the fee period, Mainstreet shall be entitled to a prorated fee based on the
 number of days during the fee period services were provided or Client will be due a
 prorated refund of fees for days services were not provided in the fee period.
 The fee schedule, which includes compensation of Mainstreet for the services is described
 in detail in Schedule A of the Qualified Plan Agreement. The Plan is obligated to pay the
 fees; however, the Plan Sponsor may elect to pay the fees. Client may elect to be billed
 directly or have fees deducted from Plan Assets. Mainstreet does not reasonably expect to
 receive any additional compensation, directly or indirectly, for its services under this
 Agreement. If additional compensation is received, Mainstreet will disclose this
 compensation, the services rendered, and the payer of compensation. Mainstreet will offset
 the compensation against the fees agreed upon under this Agreement.
