Invoices. Spark shall invoice Genable for all amounts due under a Work Order in accordance with the timing set forth in the Work Order. Invoices shall, except to the extent correctly disputed, be payable within [**] days after Genable’s receipt thereof. Genable shall be responsible for the payment of all taxes arising from any Work Order or delivery or use of the Product (other than taxes on the income of Spark arising therefrom). For the avoidance of doubt, Genable shall pay to Spark within [**] days of Spark receiving from Genable a properly executed work start order [**]% of the total cost of the Work Order.

The remaining [**]% payment shall be made within [**] days of Genable receiving the finished goods.

6.3 If applicable laws of Ireland require that withholding taxes be withheld with respect to any payments by Genable to Spark under this Agreement, Genable will: (a) deduct those taxes from the remittable payment, (b) pay the taxes to the proper taxing authority, and (c) send evidence of the obligation together with proof of tax payment to Spark on a timely basis following that tax payment. If Spark is a taxable entity in the United States and is therefore entitled to the benefits of the double taxation treaty between Ireland and the United States, and Spark provides Genable with a Form 6166 from the United States Internal Revenue Service with respect to such taxable status, at or prior to the time of any payment potentially subject to the Irish withholding tax is made hereunder, then payments made by Genable to Spark hereunder shall be made without withholding tax; provided that, if such double taxation treaty is modified after the Effective Date so that payments to Spark hereunder are subject to withholding taxes, Genable shall give notice to Spark of such change and shall pay to Spark such additional amount as may be necessary so that Spark shall receive, after deduction of such withholding tax, the amount which Spark would have received in the absence of such withholding tax less [**] percent ([**]%) of the withholding tax amount (i.e., the Parties [**] percent ([**]%) of the withholding tax amount). If Spark is not able to meet the above criteria for withholding tax treaty benefits (e.g., by ceasing to be, or by assigning its interest in this Agreement to an entity that is not, a taxable entity in the United States entitled to the benefits of the double taxation treaty between Ireland and the United States), then Genable shall make payments less any required withholding tax, and such withholding taxes required under Irish law shall be borne solely by Spark. If Genable or any successor or assign of Genable makes any payment to Spark hereunder in a manner that subjects such payment to a withholding tax obligation under the laws of any jurisdiction other than those of Ireland (i.e., either by such entity being or becoming domiciled in any jurisdiction other than Ireland or by such entity making any payment to Spark from a jurisdiction outside of Ireland), then Genable shall give notice to Spark of such requirement and shall pay to Spark such additional amount as may be necessary so that Spark shall receive, after deduction of such withholding tax, the amount which Spark would have received in the absence of such withholding tax. Each Party agrees to cooperate with the other Party in claiming refunds or exemptions from such deductions or withholdings under any relevant agreement or treaty that is in

11

effect (e.g., Genable shall not withhold Irish withholding tax without first confirming with Spark that Spark is not able to provide the documentation of its taxable status as described above). The Parties shall discuss and cooperate regarding applicable mechanisms for minimizing such taxes to the extent possible in compliance with applicable law. In addition, the Parties shall cooperate in accordance with applicable law to minimize indirect taxes (such as value added tax, sales tax, consumption tax and other similar taxes) in connection with this Agreement.
