AMENDMENT NO. 1 TO

EXCHANGE AGREEMENT

AMENDMENT NO. 1 TO EXCHANGE AGREEMENT, dated as of April 26, 2011 (this “Amendment”), among DynaVox Inc., a Delaware corporation, and the Holdings Unitholders party hereto.

WHEREAS, the Corporation and the holders of Holdings Units from time to time party thereto have entered into an Exchange Agreement, dated as of April 21, 2010 (the “Exchange Agreement”). Capitalized terms used but not defined herein shall have the meaning ascribed thereto in the Exchange Agreement;

WHEREAS, Section 4.6 of the Exchange Agreement provides that the Exchange Agreement may be amended only by the affirmative vote or written consent of each of (i) the Corporation and (ii) Holdings Unitholders holding at least two thirds of the then outstanding Holdings Units (excluding Holdings Units held by the Corporation);

WHEREAS, notwithstanding the foregoing, in addition to any other consent that may be required, the prior written consent of each of Vestar Capital Partners IV, L.P. and Edward L. Donnelly, Jr. shall also be required for any amendment of the Exchange Agreement that adversely affects such Holdings Unitholder and/or its affiliates for so long as such Holdings Unitholder continues, together with its affiliates, to hold a number of Holdings Units that is equal to or greater than 3% of the number of Holdings Units outstanding immediately following the closing of the IPO and the related repurchase of Holdings Units with the proceeds therefrom (such number to be adjusted for any subdivision or combination of the Holdings Units effected after the closing of the IPO); provided that except as otherwise provided therein (including, without limitation, in Section 2.1(d) of the Exchange Agreement), no amendment may materially and adversely affect the rights of a Holdings Unitholder, as such, other than on a pro rata basis with other Holdings Unitholders without the consent of such Holdings Unitholder (or, if there is more than one such Holdings Unitholder that is so affected, without the consent of a majority of such affected Holdings Unitholder in accordance with their holdings of Holdings Units); and

WHEREAS, this Amendment is consented to by Vestar Capital Partners IV, L.P., Edward L. Donnelly, Jr. and the other Holdings Unitholders party hereto, which parties collectively hold at least two thirds of the outstanding Holdings Units (excluding Holdings Units held by the Corporation).

NOW, THEREFORE, in consideration of the mutual agreements contained herein and for other good and valuable consideration acknowledged hereby, the parties hereto agree as follows:

1. Amendments to Exchange Agreement. (a) Section 2.1(a)(i) of the Exchange Agreement is hereby amended by adding the following new sentence immediately after the end of such section:

“Notwithstanding the foregoing, subject to Section 2.1(a)(ii) hereof, for so long as Holdings Unitholders other than the Corporation hold in excess of 25% of the outstanding Holdings Units (including Holdings Units held by the Corporation), Holdings Unitholders shall only be entitled to effect Exchanges on the second Friday or last day of each fiscal month of the Corporation occurring following the date of the initial filing by the Corporation of a Registration Statement on Form S-3 to cover delivery of shares of Class A Common Stock to Holdings Unitholders upon Exchanges; provided that Holdings Unitholders may effect Exchanges on a day that is not the second Friday or last day of a fiscal month of the Corporation during the one week period immediately following the effective date of such Registration Statement on Form S-3.”

(b) The first and second sentences in Section 2.1(b) of the Exchange Agreement are hereby amended in full to read as follows:

“A Holdings Unitholder shall exercise its right to Exchange Holdings Units as set forth in Section 2.1(a) above by delivering to the Corporation a written election of exchange in respect of the Holdings Units to be Exchanged substantially in the form of Exhibit A hereto, duly executed by such holder or such holder’s duly authorized attorney, in each case delivered during normal business hours at the principal executive offices of the Corporation; provided that, for so long as Holdings Unitholders other than the Corporation hold in excess of 25% of the outstanding Holdings Units (including Holdings Units held by the Corporation), such written election of exchange shall, as to any Exchange to be effected on the second Friday or last day of the Corporation’s fiscal month, be delivered to the Corporation at least five business days prior to the intended date of the applicable Exchange. Subject to Section 2.1(a)(ii), the Corporation shall deliver or cause to be delivered at the offices of the then-acting registrar and transfer agent of the Class A Common Stock or, if there is no then-acting registrar and transfer agent of the Class A Common Stock, at the principal executive offices of the Corporation, the number of shares of Class A Common Stock deliverable upon such Exchange, registered in the name of the relevant Exchanging Holdings Unitholder, (X) as to any Exchange to be effected on a day other than the second Friday or last day of the Corporation’s fiscal month, as promptly as practicable following the delivery of such a written election of exchange, and in any event within three business days, or (Y) as to any Exchange to be effected on the second Friday or last day of the Corporation’s fiscal month, on the second Friday or last day, as the case may be, of such fiscal month.”

2. Applicable Law. This Amendment shall be governed by, and construed in accordance with, the law of the State of Delaware.

IN WITNESS WHEREOF, the parties have caused this Amendment to be duly executed and delivered, all as of the date first set forth above.
