3.2 Arm’s Length Markup. In addition to the Reimbursed Costs described in Section 3.1, Company shall pay Service Provider hereunder an Arm’s Length Markup calculated as a percentage (as specified in Exhibit B) of particular Costs comprising the Reimbursed Costs (other than costs for employer social charges, payroll taxes on employee stock-based compensation, restructuring costs and similar types of expenses). Notwithstanding the foregoing, there shall be no markup on any Pass-Through Costs unless otherwise agreed to by the Parties in writing.

Service Provider will cooperate with and provide reasonable assistance to Company with respect to recovery, if possible, of any applicable Taxes. If the Service Payments are subject to income tax withholding, such amounts may be withheld from the Service Payments payable to Service Provider in accordance with any applicable laws. Company or its designee shall remit such withheld sums to the applicable taxing authority and upon request shall provide Service Provider with official receipts issued by the appropriate taxing authority (or such other evidence as is reasonably requested by Service Provider) to establish that any such withholding taxes have been paid.

Service Provider shall maintain adequate records of provision of Management Consulting Services to allow Company to monitor the Management Consulting Services provided and to allow proper invoices to be issued, and shall administer all financial aspects of this Agreement.

3.6 Adjustments. The Parties shall update the Arm’s Length Markup from time to time on a regular basis to ensure it remains consistent with arm’s length principles.
