No. IV.6.3 - Fixing of price by one of the parties

If the contract provides that the price is to be fixed or determined by one of parties, and this determination is manifestly unreasonable, the other party may apply to a court or arbitral tribunal to have a reasonable price fixed, notwithstanding any agreements to the contrary.

1 This Principle takes account of the fact that the parties may leave the determination of the price to one of them. If in such a scenario the price fixed by one party is manifestly unreasonable, the other party may apply to a court or arbitral tribunal to have a reasonable price fixed.

2 The party which fixes the price enjoys a certain discretion. The other party may only apply to the court or arbitral tribunal if the price fixed is "manifestly", i.e. obviously unreasonable.

3 The parties may not derogate from that provision which is intended to protect the party which does not possess the right to fix the price.

The Products and Exhibits
Except as further set forth in an exhibit to this Agreement, X in its sole discretion will determine the pricing of the Product to Customers. Any change or addition to a Product must be agreed by the parties in writing and in accordance with the applicable provisions of the applicable exhibit to this Agreement.

X agrees that the target of the Fees and costs charged to Y will be X's actual costs in performing the Services. X shall set the Fees each year as part of the Annual Budget Process at such reasonable, good faith projection of actual costs (and any overhead costs allocated according to the principle set forth in the first sentence of this Section) plus five percent (5%) of X's costs.
