(a) Actual or threatened misappropriation may be enjoined. Upon application to the court, an injunction shall be terminated when the trade secret has ceased to exist, but the injunction may be continued for an additional reasonable period of time in appropriate circumstances for reasons including, but not limited to, an elimination of commercial advantage that otherwise would be derived from the misappropriation or where the trade secret ceases to exist due to the fault of the enjoined party or others by improper means.

(b) In exceptional circumstances, if the court determines that it would be unreasonable to prohibit future use, an injunction may condition future use upon payment of a reasonable royalty for no longer than the period of time for which use could have been prohibited. Exceptional circumstances include, but are not limited to, a material and prejudicial change of position prior to acquiring knowledge or reason to know of misappropriation that renders a prohibitive injunction inequitable.

(c) In appropriate circumstances, affirmative acts to protect a trade secret may be compelled by court order.

(d) In no event shall a contract be required in order to maintain an action or to obtain injunctive relief for misappropriation of a trade secret.
