Schedule 2 CLAUSE 9

Consideration for Licence

Periodic minimum (1) Upon the date mentioned in Clause 3 (“the said date”) or upon the grant of this Licence, payments whichever is the later, and on subsequent anniversaries of the said date during the term of the Licence, the Licensee shall pay the Minister sums (in this Schedule referred to as "periodic payments") calculated as follows: (a) upon the said date, £150 multiplied by the area factor; (b) upon the 1st anniversary of the said date, £150 multiplied by the area factor; (c) ” 2nd ” £150 ” (d) ” 3rd ” £150 ” (e) ” 4th ” £300 ” (f) ” 5th ” £1200 ” (g) ” 6th ” £2100 ” (h) ” 7th ” £3000 ” (i) ” 8th ” £3900 ” (j) ” 9th ” £4800 ” (k) ” 10th ” £5700 ” (l) ” 11th ” £6600 ” (m) upon the 12th and every subsequent anniversary of the said date, £7500 multiplied by the area factor. (2) The payments specified in sub-paragraph (1) above shall be subject to variation in accordance with the following provisions: (a) The periodic payments shall be increased or subsequently reduced in line with movements in the Index of the Price of Crude Oil acquired by Refineries (published in the Digest of UK Energy Statistics) if the Minister so determines. The Minister shall give notice of any such determination ("biennial determination") during the month preceding the eighth anniversary of the date of commencement of this Licence or any subsequent two-yearly anniversary of that date, and shall specify in the notice the increase or reduction in the amount payable. Movements in the Index shall be calculated by reference to a comparison between the arithmetic mean of the Index levels for the two latest calendar years for which figures are available at the time when the determination is made, and the arithmetic mean of the Index levels for 2001 and 2002. In the event that the Index of the Price of Crude Oil acquired by Refineries ceases to be published the Minister may substitute arrangements for redetermination of periodic payments having substantially similar effect to those set out above based on such other comparable Index as he may determine. (b) The increase or reduction specified in a biennial determination shall be payable or take effect on the anniversary of the date of commencement of this Licence next following the date of the relevant determination. (c) No biennial determination shall have effect so as to reduce the periodic payments below the levels set out in sub-paragraph (1) above. (d) The Minister shall not make a biennial determination increasing or reducing the amounts payable where that increase or reduction would be 5% or less of the levels set following the previous biennial determination. (3) In this Schedule “the area factor” means the number of square kilometres comprised in the Licensed Area at the date upon which the periodic payment in question becomes due.
