Subject to paragraphs (8) and (9) of this clause, the value of petroleum delivered to the Minister in pursuance of clause 10 of this licence shall be ascertained for the purposes of this clause and clause 8A on such basis (or, where petroleum of more than one kind is delivered, such bases) as the Minister and Licensee agree.

8

If the Minister and the Licensee fail to agree on the value of any petroleum delivered to the Minister in pursuance of clause 10 of this licence, it shall be ascertained on such basis as the Minister may specify as fair in a notice in writing given by him to the Licensee.

The Licensee may, during the period of 28 days beginning with the day on which he receives a notice from the Minister under paragraph (8) of this clause, refer to arbitration in the manner provided by clause 40 of this licence any question as to whether the basis of valuation specified in the notice is fair.

If in any chargeable period the Licensee delivers to the Minister in pursuance of clause 10 of this licence petroleum having a value greater than the appropriate percentage of the aggregate of—

the value of the petroleum delivered (ignoring any such excess as is mentioned in clause 8(10) of this licence), and

the value of the petroleum relating to that period,

the Minister shall pay to the Licensee a sum equal to the difference.

If a payment is made by the Minister in pursuance of clause 8A of this licence more than two months after the end of the chargeable period to which the payment relates, an amount in respect of interest on the payment from the end of those two months shall also be payable by him to the Licensee.

8B

Interest under paragraph (8A) of this clause shall be calculated in such manner as the Minister may specify from time to time in a notice in writing given by him to the Licensee (but sub-paragraph (a) of paragraph (8) of this clause shall apply to such a notice as it applies to a notice under paragraph (8)).

from each part of the licensed area which is an oil field for the purposes of the Oil Taxation Act 1975,

c

from each well producing petroleum from a part of the licensed area which is not within such an oil field.
