Notwithstanding termination of this Agreement, neither Party shall be relieved of any of its respective obligations and liabilities arising hereunder prior to the effective date of such termination.

ARTICLE 4

COMPENSATION; RECORDS

4.1         Compensation. Subject to the terms and conditions of this Agreement, Company agrees to pay, and Consultant agrees to accept, as compensation for the Services, payment at a rate of $500 per hour. Company shall also timely reimburse Consultant for reasonable expenses incurred by Consultant while performing Services; provided, however, that Consultant shall not incur expenses greater than $100 per day without Company’s express written authorisation.

4.2         Hours Cap. There is no formal cap to the hours Consultant may work hereunder but neither Company nor Consultant intend for Consultant to perform Services requiring or consuming more than 20 percent of the time Consultant spent in the ordinary course of his employment with Company as defined as the average level of bona fide services performed by Consultant for Company over the 36-month period ending on the Effective Date. As of the Effective Date, the Parties intend that Consultant shall have incurred a “separation from service” with the Company and its Affiliates as determined under Section 409A of the Code, and this Agreement shall be administered and interpreted by the Parties in a manner that is consistent with such intent.

4.3         Invoices. Consultant shall submit monthly or project-based invoices to Company for Services as agreed with Company at the outset of any assignment. Except as otherwise authorised in writing by Company, all invoices shall include the information requested by Company and shall be submitted in accordance with the Company’s invoicing instructions through the Company’s electronic invoicing system or to such other location as Company designates in writing (including by e-mail) to Consultant. All invoices must be supported by the following documentation:

Company reserves the right to request additional information regarding Consultant’s invoices. All invoices must be rendered within sixty (60) days after the end of the month in which the Services have been performed, and any invoice not received within such sixty (60) day period shall not be paid unless there has been advance written consent to such delay by Company.

4.4         Time of Payment. Company shall pay undisputed invoices properly submitted in compliance with the requirements of this Agreement within sixty (60) days from the date that the invoice is received by Company in accordance with this Agreement. Invoice payment is contingent on the following conditions: (i) the invoice conforms to the requirements specified in this Article 4; (ii) all Services have been performed for the relevant time period; (iii) Company has been furnished all information with respect to the invoice that may have been requested by it under the terms of this Agreement; and (iv) all other conditions precedent for payment have been fulfilled. It is understood and agreed, however, that payment by Company of an invoice, disputed or undisputed, shall not constitute a waiver of Company’s right subsequently to audit or otherwise question or contest the amount or correctness of such invoice, and to obtain reimbursement.

4.5         Disputed Charges. Company shall have the right to dispute in good faith any charge contained in any invoice. In the event Company disputes an invoice, in whole or in part, Company shall reject the invoice and provide Consultant with prompt notification of all reason(s) for such rejection; provided, however, that such notice shall be delivered to Consultant within thirty (30) days of the Company’s receipt of the invoice in question. Unless otherwise directed by Company, Consultant shall submit a new invoice revised to include only the undisputed amounts and the time for payment shall commence only upon receipt of such undisputed invoice. With respect to the disputed items in an invoice, which shall not accrue interest, Company and Consultant shall work together in good faith to resolve such disputed items. Any payment of a disputed amount by Company shall not act as a waiver of its rights, including the right to seek reimbursement. Furthermore, Company shall not be obligated to pay any invoice (nor shall interest accrue thereon) that is not submitted in strict compliance with Company’s invoicing procedures as set forth in Article 4.
