(a) Except as provided in Subsection (c) of this section, a court may award the promisee under a covenant not to compete damages, injunctive relief, or both damages and injunctive relief for a breach by the promisor of the covenant.
(b) If the primary purpose of the agreement to which the covenant is ancillary is to obligate the promisor to render personal services, for a term or at will, the promisee has the burden of establishing that the covenant meets the criteria specified by § 15.50 of this code. If the agreement has a different primary purpose, the promisor has the burden of establishing that the covenant does not meet those criteria. For the purposes of this subsection, the “burden of establishing” a fact means the burden of persuading the triers of fact that the existence of the fact is more probable than its nonexistence.

(c) If the covenant is found to be ancillary to or part of an otherwise enforceable agreement but contains limitations as to time, geographical area, or scope of activity to be restrained that are not reasonable and impose a greater restraint than is necessary to protect the goodwill or other business interest of the promisee, the court shall reform the covenant to the extent necessary to cause the limitations contained in the covenant as to time, geographical area, and scope of activity to be restrained to be reasonable and to impose a restraint that is not greater than necessary to protect the goodwill or other business interest of the promisee and enforce the covenant as reformed, except that the court may not award the promisee damages for a breach of the covenant before its reformation and the relief granted to the promisee shall be limited to injunctive relief. If the primary purpose of the agreement to which the covenant is ancillary is to obligate the promisor to render personal services, the promisor establishes that the promisee knew at the time of the execution of the agreement that the covenant did not contain limitations as to time, geographical area, and scope of activity to be restrained that were reasonable and the limitations imposed a greater restraint than necessary to protect the goodwill or other business interest of the promisee, and the promisee sought to enforce the covenant to a greater extent than was necessary to protect the goodwill or other business interest of the promisee, the court may award the promisor the costs, including reasonable attorney’s fees, actually and reasonably incurred by the promisor in defending the action to enforce the covenant.
