Okla. Stat. tit. 71, § 71-417: Discrimination prohibited

No offeror shall make a multinational corporation take-over bid

which is not made to all holders residing in this state of the

equity security that is the subject of such multinational

corporation take-over bid, or which is not made to such holders on

the same terms as such multinational corporation take-over bid is

made to holders of such equity security not residing in this state.

If an offeror makes a tender offer or request or invitation for

tenders for less than all the outstanding equity securities of a

class, and if a greater number of securities is deposited pursuant

thereto within ten (10) days after copies of the offer or request or

invitation for tenders are first published or sent or given to

security holders that such offeror is bound or willing to take up

and pay for, the securities shall be taken up as nearly as may be

pro rata, disregarding fractions, according to the number of

securities deposited by each offeree. This section shall apply to

securities deposited within ten (10) days after notice of an

increase in the consideration offered to security holders, as

described in this section, is first published or sent or given to

security holders. If the terms of a multinational corporation take-

over bid are changed before its expiration by increasing the

consideration offered to offerees, the offeror shall pay the

increased consideration for all equity securities taken up, whether

the same are deposited or taken up before or after the change in the

terms of the multinational corporation take-over bid.
