Okla. Stat. tit. 6, § 6-1101: Merger or conversion

A. Resulting State Bank. Upon approval of the Board, banks or

savings associations may be merged with or converted into a

resulting state bank as hereafter prescribed, except that the action

by a constituent national bank or federal savings association shall

be taken in the manner prescribed by and shall be subject to any

limitation or requirements imposed by any law of the United States

which shall also govern the rights of its dissenting shareholders.

B. Resulting National Bank. Nothing in the law of this state

shall restrict the right of a state bank or state savings

association to merge with or convert into a resulting national bank.

The action to be taken by a constituent state bank or state savings

association and its rights and liabilities and those of its

shareholders shall be the same as those prescribed for national

banks at the time of the action by the applicable laws of the United

States and not by the laws of this state. Upon the completion of

the merger or conversion into a national bank, all authority and the

charter of any merging or converting state bank or state savings

association shall automatically terminate.
