(b) The Company shall withhold from any payments all federal, state, local or other taxes that are legally required to be withheld.

(c) Any payments due hereunder for Severance Pay and Pro-Rated Bonus Payment shall be reduced by any other severance or termination payment due to a Participant, including, by way of illustration and not limitation, any amounts paid pursuant to federal, state or local government worker notification (e.g., Worker Adjustment and Retraining Notification (W.A.R.N.)

In addition, to the extent any federal, state or local government regulation provides for payments related to accrued wages, bonuses, commissions, reimbursements, flextime or other benefits in an amount or manner different from the Employer’s policies and programs, including this Program, any payments hereunder for Severance Pay and Pro-Rated Bonus Payment shall be offset by such amounts.

In addition, a Participant that is subject to an Employer commission plan or arrangement shall receive all commissions properly earned, but not yet paid, in accordance with the terms of such plan or arrangement. All payments shall be subject to proper tax withholding.

3.7 Settlement of Accounts: The Company may deduct (after all applicable tax withholdings have been deducted) from payments hereunder any indebtedness, obligation or liability owed by the Participant to an Employer as of his or her date of termination, as permitted under applicable law.

ARTICLE 4

MISCELLANEOUS

4.1 Employment Status: This Severance Program does not constitute a contract of employment or impose on an Employer any obligation to retain any Eligible Employee as an employee or to change any employment policies of an Employer. Upon a Qualifying Termination hereunder, an Eligible Employee will thereafter cease to be an employee for any purpose.

4.2 Right to Amend or Terminate: The Company, by action of the Board or its duly authorized delegee, reserves the right at any time and from time to time to amend or terminate this Severance Program; provided, however, that subsequent to any Closing Date, the Program and each of the Severance Policies, all as in effect at the Closing Date, shall be maintained in substance and effect for at least 24 months following any Closing Date, subject only to administrative, process or other amendments or changes that do not materially affect the rights of Eligible Employees hereunder. In the event a Change of Control is structured as a sale of all or substantially all of the assets of the Company, the Company will negotiate for the Acquirer to assume and perform the obligations of the Company hereunder.

4.3 Large Scale Reduction in Force: In the event of a large scale reduction in force and except as otherwise limited by Section 4.2, the Company reserves the right, on its behalf and on behalf of all Employers, to reduce, due to economic factors, the benefits set forth in Article 3 of the Severance Program.

4.4 Code Section 409A: It is the intention of the parties that no payment or entitlement pursuant to this Program will give rise to any adverse tax consequences to any person pursuant to Code Section 409A. The Administrator shall interpret and apply the Program to that end, and shall not give effect to any provision herein in a manner that reasonably could be expected to give rise to adverse tax consequences under Code Section 409A; provided, however, that nothing herein shall require an Employer to provide a Participant with any gross-up for any tax, interest or penalty that may be incurred under Code Section 409A or otherwise. Any reimbursement due or expenses to be paid under any provision of this Severance Program shall be paid not later than March 15 of the year following the year in which the expense is incurred. In the case of any payment on termination (other than in compliance with the requirements of Treas. Reg. §1.409A-1(b)(9)(iii) or (v) or of any successor thereto or any other provision that exempts a payment from Code Section 409A and other than any payment that is a “short-term deferral” within the meaning of Treas. Reg. §1.409A-1(b)(4)(i)) while a Participant is a specified employee within the meaning of Code Section 409A(a)(2)(B)(i), in no event will such payment be made earlier than six months after the Participant’s “separation from service” within the meaning of Treas. Reg. §1.409A-1(h). In the event that, due to Code Section 409A, a Participant does not receive one or more cash payments that would otherwise be due during that six-month period, all such delayed payments will be made on the first day after the six-month anniversary of his or her “separation from service” within the meaning of Treas. Reg. §1.409A-1(h), and thereafter any remaining payments shall be made in accordance with any existing schedule.
