provided, that in the event oil on which such tax becomes due is not

sold at the time of production, but is retained by the producer, the

tax on such oil not so sold shall be paid by the producer including

the tax due on royalty oil not sold; and provided, further, that in

settlement with royalty owner, such producer shall have the right to

deduct the amount of tax so paid on royalty oil, or to deduct

therefrom royalty oil equivalent in value at the time such tax

becomes due with the amount of tax paid.

The provisions of this subsection shall terminate on June 30,
