The central issue of this summary judgment appeal is whether former employees ratified a release waiving all discrimination claims against their former employer thereby precluding later suit for age discrimination. Concluding that they have, we affirm the summary judgment.

On May 3, 1993, appellee Lomas Information Systems, Inc. ("Lomas") terminated appellants Tom Blakeney, Michael Blohm, Robert S. Huffer, Erin Phelps, James Ruska, Linn Madsen, Kathy Howell, and Mike Sweet (collectively "the employees"). In accordance with Lomas's 1993 Reduction in Force Program, each employee was entitled to severance benefits as consideration for signing a document entitled "General Release." This release included a broad waiver of all discrimination claims.1 Each employee voluntarily signed the release and received the appropriate severance pay.

Despite having signed the release specifically waiving all discrimination claims, the employees subsequently filed charges of unlawful age discrimination with the Equal Employment Opportunity Commission. On July 18, 1994, the former employees sued Lomas alleging that they were victims of age discrimination when Lomas terminated them and when the company failed to rehire them. To escape the effect of the release, the employees alleged that it had no force because it failed to comply with the provisions of the Older Workers Benefit Protection Act, Pub.L. No. 101-433, 104 Stat. 978 (codified at 29 U.S.C. Sec. 626(f)) ("OWBPA").

In the district court, Lomas moved for summary judgment on the ground that the employees waived their right to sue by signing the release and retaining their severance benefits. The district court agreed and granted summary judgment for Lomas on that basis. The court concluded that the release, while failing to meet the requirements of the OWBPA, created a voidable contract which the employees ratified by retention of the severance pay. The employees appeal contending primarily that failure to comply with the OWBPA precludes ratification of the release.

We review the granting of a summary judgment de novo under well-established standards. See Celotex Corp. v. Catrett, 477 U.S. 317, 323-24, 106 S. Ct. 2548, 2552-53, 91 L. Ed. 2d 265 (1986); Sterling Property Management, Inc. v. Texas Commerce Bank, Nat'l Ass'n, 32 F.3d 964, 966 (5th Cir.1994).

The OWBPA amended the Age Discrimination in Employment Act ("ADEA") to enable an employer to enforce a waiver of age discrimination claims. See 29 U.S.C. Sec. 626(f)(1). Section 626(f)(1) provides that an individual may not waive rights under the statute unless the waiver is "knowing and voluntary." To constitute a knowing and voluntary waiver, the release must meet specific statutory requirements such as specifically referring to the ADEA, advising the individual to consult with an attorney, and providing a grace period to consider signing the agreement. See 29 U.S.C. Secs. 626(f)(1)(B), (E), (F).

It is undisputed that the release signed by the employees failed to meet these statutory requirements. The parties, however, disagree about the effect of this deficiency. Relying on our decision in Wamsley v. Champlin Refining & Chemicals, Inc., 11 F.3d 534 (5th Cir.1993), cert. denied, --- U.S. ----, 115 S. Ct. 1403, 131 L. Ed. 2d 290 (1995), Lomas contends that the defective release was not void, but merely voidable at the employees' election. As such, the release could be subsequently ratified by failing to timely tender the consideration on which the initial voidable contract was based. Confronted with this authority, the employees argue that Wamsley does not control because Lomas made no attempt to comply with the statutory requirements of section 626(f)(1).

We believe Wamsley, which is binding on this Court, does control the outcome of this appeal. In Wamsley, we held that failure to meet the requirements outlined in section 626(f)(1)(A)-(H) did not create a void contract, but merely a voidable one. 11 F.3d at 539. Failure to tender back the consideration for the promise not to sue, manifests an intention to be bound by the terms of the waiver. Id. at 540. This ratification creates a new promise and a new obligation that is enforceable despite the waiver's failure to meet the statutory requirements. Id. at 540 n. 11. While it is true that the Wamsley release contained the bulk of the requirements outlined in section 626(f)(1), our discussion of the voidability of the release did not hinge on substantial compliance with the OWBPA. Rather, it was rooted in the fact that failure to comply with any of the waiver requirements merely renders the release not "knowing and voluntary" as required by the statute. Such defective waivers "are subject to being avoided at the election of the employee." Id. at 539; see Wittorf v. Shell Oil Co., 37 F.3d 1151, 1154 (5th Cir.1994). Substantial compliance is not a prerequisite. A waiver either meets all the requirements of section 626(f)(1) and is valid under the OWBPA, or it fails to meet the requirements and is voidable. In this case, the release failed to meet the statutory requirements and was therefore voidable.

The employees, however, did not exercise this option. Instead, they chose to keep the benefit of their bargain, the severance pay. Retaining the consideration after learning that the release is voidable constitutes a ratification of the release. Wittorf, 37 F.3d at 1154; Grillet v. Sears, Roebuck & Co., 927 F.2d 217, 220 (5th Cir.1991). To properly rescind the contract, the employees had to meet two burdens. Initially, they had to restore the status quo ante. Grillet, 927 F.2d at 220. Secondly, their rescission had to occur shortly after the discovery of the alleged deficiency. Id. at 221. In this case, the employees did neither. They made only a belated tender, after suit was filed, to return that part of the severance pay that was attributable to age discrimination claims.2 This offer not only fails to return the status quo, but by any standard is untimely.3 See Id. at 220-21. As a result, the employees have ratified the release.

In an attempt to revive their lawsuit, the employees argue that the ratification of the release only applies to their termination claims and not their rehiring claims. According to the employees, because they cannot prospectively waive age discrimination claims, summary judgment was improper on the rehiring claim. This argument, however, is unpersuasive because the rehiring claim is not a future claim. In the release, the employees waived all rights to suit arising out of their termination. The employees' cause of action for failure to rehire is simply an attempt to revive claims they were paid to release. Any claim concerning failure to rehire certainly arises out of their termination and was extant when the release was ratified.

We conclude that the district court properly granted summary judgment because no genuine issue of material fact exists and Lomas is entitled to a judgment as a matter of law.4 As a matter of law, the employees ratified the release thereby waiving all claims of age discrimination. The summary judgment is AFFIRMED.
