"an employer offered to pay a terminated employee $50,000 to release all claims the employee might have against the employer. the employee orally accepted the offer. the employer then prepared an unsigned release agreement and sent it to the employee for him to sign. the employee carefully prepared, signed, and sent to the employer a substitute release agreement that was identical to the original except that it excluded from the release any age discrimination claims. the employer signed the substitute release without reading it. shortly thereafter, the employee notified the employer that he intended to sue the employer for age discrimination. is the employer likely to prevail in an action seeking reformation of the release to conform to the parties’ oral agreement?
