Sec. 106. Sale of Military Equipment, Materials, and Services.— (a) The President may, in order to carry out the purpose of this chapter, sell or enter into contracts (without requirement for charge to any appropriation or contract authorization) for the procurement for sale of equipment, materials, or services to any nation or international organization: Provided, That prior to the transfer of any such equipment, materials, or services to any nation which has not signed an agreement under section 142 of this Act or joined with the United States in a regional collective defense arrangement, the President shall have received commitments satisfactory to him that such equipment, materials, or services are required for and will be used by such nation solely to maintain its internal security, its legitimate self-defense, or to permit it to participate in the defense of the area of which it is a part, or in collective security arrangements and measures consistent with the Charter of the United Nations, and that it will not undertake any act of aggression against any other state. (b) Whenever equipment or materials are sold from the stocks of or services are rendered by any United States Government agency to any nation or international organization as provided in subsection (a), such nation or international organization shall first make available the fair value, as determined by the President, of such equipment, materials, or services before delivery or, when the President determines it to be in the best interests of the United States, within sixty days thereafter or, as determined by the President, within a reasonable period not to exceed three years. The fair value for the purpose of this subsection shall not be less than the value as defined in subsection (h) of section 545: Provided, That with respect to excess equipment or materials the fair value may not be determined to be less than (i) the minimum value specified in that subsection plus the scrap value, or (ii) the market value, if ascertainable, whichever is the greater. Before a contract for new production is entered into, or rehabilitation work is undertaken, such nation or international organization shall (A) provide the United States with a dependable undertaking to pay the full amount of such contract or the cost of such rehabilitation which will assure the United States against any loss on the contract or rehabilitation work, and (B) shall make funds available in such amounts and at such times as may be necessary to meet the payments required by the contract or the rehabilitation work in advance of the time such payments are due, in addition to the estimated amount of any damages and costs that may accrue from the cancellation of such contract or rehabilitation work.
