Consultant shall keep reasonably detailed records of all hours worked on Decibel’s behalf under this Agreement and shall make those records available to Decibel upon Decibel’s reasonable request. Each party represents that, to the best of its knowledge, the fee set forth in Schedule A constitutes fair market value for the Services. Consultant shall provide said summary of Services to the attention of Accounts Payable for Services rendered hereunder with a copy to the attention of the V.P. Finance.
