Okla. Stat. tit. 62, § 62-589: Collection of costs - Reimbursement

A. An issuer, prior to or at original issuance of registered

public obligations, may provide as a part of a system of

registration that the transferor or transferee of the registered

public obligations pay all or a designated part of the costs of the

system as a condition precedent to transfer, that costs be paid out

of proceeds of the registered public obligations, or that both

methods be used. The portion of the costs of the system not

provided to be paid for by the transferor or transferee or out of

proceeds shall be the liability of the issuer.

B. The issuer may as a part of a system of registration provide

for reimbursement or for satisfaction of its liability by payment by

others. The issuer may enter into agreements with others respecting

such reimbursement or payment, may establish fees and charges

pursuant to such agreements or otherwise, and may provide that the

amount or estimated amount of such fees and charges shall be

reimbursed or paid from the same sources and by means of the same

collection and enforcement procedures and with the same priority and

effect as with respect to the obligations.
