Where the Board would otherwise be expressly liable to make payment by way of a claim to Project Co including amounts which, in turn, comprise amounts payable to any Sub-Contractors payable by Project Co, the Board shall not be entitled to withhold, reduce or avoid any such payment to Project Co in reliance only on the fact that the amount which is due from Project Co to the Sub-Contractor or the entitlement of the Sub-Contractor to payment of such amount as a result of the circumstances giving rise to the Board's obligation to pay under such claim, is conditional on the entitlement of, or receipt of payment by Project Co from the Board
