How to analyze this case using the I.R.A.C. Method

Case #4 Elizabeth Salsbury, a speech language pathologist employed by SunDance, was notified by letter from SunDance dated February 26, 1999, that the company was compelled to reduce its workforce and that Salsbury's job would be terminated effective March 1, 1999. The letter informed Salsbury that she would receive 80 hours' worth of severance pay after signing a separation agreement and general release. A provision of the agreement stated, "This Release and covenant not to sue also expressly, and without any limitation of the foregoing General Release, includes bot is not limited to any claims which Releasor may have or may assert under federal or state law prohibiting employment discrimination and claims growing out of any legal restrictions on the rights of Company to terminate its employees, whether statutory or arising under common law, including without limitations: Title VII of the Civil Rights Act of 1964 and the Americans with Disabilities Act. Releasor on behalf of herself and other releasers expressly agrees that she will not institute, commence, prosecute or otherwise pursue any proceeding, action, complaint, claim, charge or grievance against Company or any other released parties in any administrative, judicial or other forum whatsoever with respect to any acts or events occurring prior to the date hereof in the course of Releasor's dealing with Releasee." Salsbury decided not to sign the Separation Agreement. Question: Can severance pay be given conditional to the employee's promise to forego proceeding under Title VII of the Civil Rights Act and/or the Americans with Disabilities Act? Explain
