(2) the consumer is not in a significantly disparate bargaining position; and
(3) the consumer is represented by legal counsel in seeking or acquiring the goods or services.
(b) A waiver under Subsection (a) is not effective if the consumer's legal counsel was directly or indirectly identified, suggested, or selected by a defendant or an agent of the defendant.
(c) A waiver under this section must be:
(1) conspicuous and in bold-face type of at least 10 points in size;
(2) identified by the heading "Waiver of Consumer Rights," or words of similar meaning; and
(3) in substantially the following form:
(d) The waiver required by Subsection (c) may be modified to waive only specified rights under this subchapter.
(e) The fact that a consumer has signed a waiver under this section is not a defense to an action brought by the attorney general under Section 17.47.
