Okla. Stat. tit. 79, § 79-208: Acquisition of stock or assets of competitor

No person engaged in trade or commerce in this state shall

acquire, in any manner whatever, the stock or the whole or any part

of the assets of any competing person engaged in the same or similar

line of trade or commerce, in or out of this state, where, in any

relevant market in this state or in any line of trade or commerce in

this state, the effect of the acquisition is to substantially lessen

competition or to tend to create a monopoly; provided, however, that

this section shall have no application to corporations owning or

holding the stock of subsidiary corporations when the ownership of

stock in subsidiary corporations does not violate Section 3 of this

act.
