The agreement also reserved the "coal and asphalt lands" from the allotment process. These lands were to be sold or leased and the proceeds used for the benefit of the two tribes.
Under this agreement, the tribal governments were to be terminated on March 4, 1906.
The two tribes ratified the document in November, 1897. However, Chickasaw law required that it be submitted to the voters of the Chickasaw Nation, who rejected it. The Curtis Act required that the Atoka Agreement be resubmitted to the voters of both nations. The agreement was approved in a joint election on August 24, 1898.
