In the event the Secretary and a participating Indian tribe are unable to agree, in whole or in part, on the terms of a compact or funding agreement (including funding levels), the Indian tribe may submit a final offer to the Secretary. Not more than 45 days after such submission, or within a longer time agreed upon by the Indian tribe, the Secretary shall review and make a determination with respect to such offer. In the absence of a timely rejection of the offer, in whole or in part, made in compliance with subsection (c) of this section, the offer shall be deemed agreed to by the Secretary.
