The mediation committee reconvened on 25 December and agreed to increase the child payments to JPY30,000 (USD83) per child. The Mutual Aid Society held a vote of its members but the agreement was rejected by a single vote. Society leader Watanabe offered his resignation in protest but when another vote was held on 27 December members accepted the agreement and his resignation was withdrawn. As usual, the agreement did not admit responsibility for Minamata disease. The payments were "sympathy money" and the agreement included a clause that, "Even if in the future it is determined that the cause of Minamata disease "is" the factory's wastewater, patients will make absolutely no further demands for compensation", along with an extra clause that, "If in the future it is determined that the cause of Minamata disease is "not" the factory's wastewater, the company shall end payments at the end of that month." The final agreement was accepted by both sides on 29 December 1959.
