Buyback contracts. Another contract which involves a license and a transfer of technology, is buyback. In fact buyback is a counter trade type of contract. In this series of contracts, Issuer undertakes additional and mutual commitments in addition to the common commitments of goods and services ‘contracts. (Xxxxxxx, 2004, p. 5). One of the properties of buyback, compared with "counter purchase," which is another kind of counter trade agreement, is the coherence and relationship between the exported goods and redeem of the exporter. In fact, what is exported and what is purchased are linked in a manufacturing process in a buyback contract. Exporter is committed to the supply of machinery, raw materials, technology, technical knowledge and technical assistance to the importer so that an economic unit is created. When the unit is built, the cost of exported products is compensated through the redemption of the goods produced in “the very economic unit ". (Ibid., Pp. 16, 17). It seems that in addition to the investment and financing of projects, transfer of technology and technical knowledge is one of the objectives of the contracts and, therefore, so the raw materials (hardware), technical management services (software), patents licensing’s rights and other industrial ownerships are recorded as buyback contracts. In our country the buyback mechanism is usually used to extract oil and gas deposits or develop them. In the foreign investment law and its regulations, the buyback and BOT contracts are investments in which the return of interests are purely possible through the operation of the projects, and does not rely on state guarantees or banks1
