Okla. Stat. tit. 12 § 98
When a cause of action accrues against a person and that person is out of the state or has concealed himself, the period limited for the commencement of the action shall not begin to run until he comes into the state, or while he is concealed. If, after a cause of action accrues against a person and that person leaves the state or conceals himself, the time of his absence or concealment shall not be computed as any part of the period within which the action must be brought. Provided, however, that if any statute which extends the exercise of personal jurisdiction of courts over a person or corporation based upon service outside this state, or based upon substituted service upon an official of this or any other state or nation, or based upon service by publication permits the courts of this state to acquire personal jurisdiction over the person, the period of his absence or concealment shall be computed as part of the period within which the action must be brought.
