The Employment Agreement also provides that if Ms. Schmidt's employment is terminated (i) by the Company without "cause" or (ii) by Ms. Schmidt for "good reason" (each, a "Qualifying Termination"), then, provided that Ms. Schmidt timely executes and does not revoke a release of claims and abides by the restrictive covenants included in the Employment Agreement, Ms. Schmidt will be eligible to receive: (A) a severance payment, payable in 12 substantially equal installments, in an aggregate amount equal to (i) one (the "Severance Multiple") multiplied by (ii) the sum of: (x) Ms. Schmidt's base salary for the year in which such termination occurs and (y) Ms. Schmidt's then-current target annual bonus; (B) a prorated annual bonus for the year in which such Qualifying Termination occurs, subject to achievement of the applicable performance criteria; and (iii) if Ms. Schmidt elects COBRA continuation coverage, monthly reimbursement for the amount paid by Ms. Schmidt to continue such coverage for up to 18 months following the date of such Qualifying Termination. If such Qualifying Termination occurs within 24 months following a change in control, the Severance Multiple will be equal to two.
