References under this Letter Agreement to your termination of employment shall be deemed to refer to the date upon which you have experienced a “separation from service” within the meaning of Section 409A of the Code. Each payment made under this Letter Agreement shall be designated as a “separate payment” within the meaning of Section 409A of the Code.

Reg. Section 1.409A-3(i)(1)(iv).

8. No Additional Payments: The payments and benefits described in this Letter Agreement will be the only such payments and benefits you are to receive in connection with the

5

termination of your employment with the DynaVox Group and you acknowledge and agree you are not entitled to any additional payments, rights or benefits not otherwise described in this Letter Agreement. You hereby acknowledge and agree that you are not eligible to be a participant in any severance or incentive compensation plan of any member of the DynaVox Group. Any payments, rights or benefits received under this Letter Agreement will not be taken into account for purposes of determining benefits under any employee benefit plan of any member of the DynaVox Group, except to the extent required by law, or as otherwise expressly provided by the terms of such plan.

9. Legal Fees: DynaVox shall promptly reimburse you for the reasonable legal fees incurred by you in connection with the negotiation of this Letter Agreement, subject to (x) receiving customary back-up and supporting documentation regarding such fees and (y) a cap of $25,000. Payment in respect of approved legal fees shall be made no later than 30 days after your provision of customary back-up and supporting documentation and in accordance with Section 7.

10. No Mitigation; Offset: You will not be required to mitigate damages with respect to the termination of your employment under the Employment Agreement by seeking other employment or otherwise, and there will be no offset against amounts due to you under this Letter Agreement on account of subsequent employment. Additionally, amounts owed to you under this Letter Agreement will not be offset by any claims any member of the DynaVox Group may have against you.

11. Assignment: This Letter Agreement, and all of your rights and duties hereunder, shall not be assignable or delegable by you. Any purported assignment or delegation by you in violation of the foregoing shall be null and void ab initio and of no force and effect. This Letter Agreement shall be assigned to any successor of DynaVox. Upon such assignment, the rights and obligations of DynaVox hereunder shall become the rights and obligations of such affiliate or successor person or entity.

12. Successors; Binding Agreement: This Letter Agreement shall inure to the benefit of and be binding upon personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

Judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.

14. Governing Law: The validity, interpretation, construction, and performance of this Letter Agreement shall be governed by the laws of the State of Delaware without regard to its principles of conflicts of law.

15. Withholding: Notwithstanding any other provision of this Letter Agreement, any payments or benefits hereunder will be subject to the withholding of such amounts, if any,

6

relating to tax and other payroll deductions as DynaVox reasonably determines it should withhold pursuant to any applicable law or regulation.

16. Severability: In the event that any one or more of the provisions of this Letter Agreement shall be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this Letter Agreement shall not be affected thereby.
