Funds derived from offshore mineral leases and held in escrow under agreement between the state and the United States pending settlement of the dispute between the parties shall be deposited in the state treasury when received. Upon such settlement, these funds and the interest from their investment, except the portion otherwise allocated or dedicated by this constitution, shall be used by the state treasurer to purchase, retire, or pay in advance of maturity the existing bonded indebtedness of the state or shall be invested for that purpose. If any of these funds cannot be so expended within one year, the legislature may appropriate annually, for capital improvements or for the purchase of land, ten percent of the remaining funds, not to exceed ten million dollars in one year.
