Fees for the Services provided hereunder are based on the billing rates set forth in the applicable Statement of Services. Client will reimburse RGP for actual expenses incurred by Consultants in connection with the performance of Services which are consistent with Client's expense policy, a copy of which will be provided by Client concurrent with its execution of this Agreement, and documented with itemized receipts. Any travel by Consultant must be pre-approved by Client. Fees and applicable expenses will be billed weekly, payable upon receipt of RGP's invoices. Should Client dispute the amount of any fees or expenses, resolution of the dispute will not delay payment of the remainder of such invoice. If the Statement of Services provides for Client to pay a retainer prior to the commencement of Services, fees will not be billed against the retainer. RGP reserves the right to collect interest or other penalty from Client for promptly submitted invoices or, in the event of a dispute, for the undisputed portion thereof, upon which payment is not received within thirty (30) days of Client's receipt of such invoice. Specifically, RGP will be entitled to a late charge of the lesser of (i) 11/2% per month or (ii) the highest rate allowable by law, in each case compounded monthly to the extent allowable by law. RGP further reserves the right to withdraw all Consultants provided to Client and to cease performing Services hereunder if any invoice is not promptly paid when due.
