teṣāṃ jyāyaso 'dhikenāṃśena samāt samena hīnādd hīneneti samasaṃdhiḥ //

When the kings of superior, equal or inferior power make peace with the conqueror and agree to pay a greater, or equal, or less amount of profit in proportion to the army supplied, it is termed even peace; that which is of the reverse character is styled uneven peace; and when the profit is proportionally very high, it is termed deception (atisandhi).
