ARTICLE IV

TRANSFERS OF SECURITIES

4.1           Tag-Along Rights.

(a)           Tag-Along Rights.  Prior to making any Transfer of Vestar Securities (other than a Transfer described in Section 4.1(b)) any holder of Vestar Securities proposing to make such a Transfer (for purposes of this Section 4.2, a “Selling Holder”) shall give at least thirty (30) days’ prior written notice to each holder of Park Avenue Securities or Other Investor Securities (for purposes of this Section 4.1, each an “Other Holder”), to the Corporation and to Holdings, which notice (for purposes of this Section 4.1, the “Sale Notice”) shall identify the type and amount of Vestar Securities to be sold (for purposes of this Section 4.1, the “Offered Securities”), describe the terms and conditions of such proposed Transfer, and identify each prospective Transferee.  Any of the Other Holders may, within fifteen (15) days of the receipt of the Sale Notice, give written notice (each, a “Tag-Along Notice”) to the Selling Holder that such Other Holder wishes to participate in such proposed Transfer upon the terms and conditions set forth in the Sale Notice, which Tag-Along Notice shall specify the Park Avenue Securities or Other Investor Securities such Other Holder desires to include in such proposed Transfer; provided, however, that (1) each Other Holder shall be required, as a condition to being permitted to sell Park Avenue Securities or Other Investor Securities pursuant to this Section 4.1(a) in connection with a Transfer of Offered Securities, to elect to sell Park Avenue Securities or Other Investor Securities of the same type and class and in the same relative proportions as the Securities which comprise the Offered Securities, (2) no Security that is at the time in question subject to vesting, forfeiture, repurchase or similar provisions shall be entitled to be sold pursuant to this Section 4.1(a) except to the extent that such vesting, forfeiture, repurchase or similar provisions have lapsed prior thereto or will lapse in accordance with the terms thereof upon the consummation of such transaction; and (3) to exercise its tag-along rights

5

hereunder, each Other Holder must agree to make to the Transferee the same representations, warranties, covenants (other than any non-competition covenants), indemnities and agreements as the Selling Holder agrees to make in connection with the Transfer of the Offered Securities (except that in the case of representations and warranties pertaining specifically to, or covenants made specifically by, the Selling Holder, the Other Holders shall make comparable representations and warranties pertaining specifically to (and, as applicable, covenants by) themselves), and must agree to bear his or its ratable share (which may be joint and several but shall be based on the value of Securities that are Transferred) of all liabilities to the Transferees arising out of representations, warranties and covenants (other than those representations, warranties and covenants that pertain specifically to a given Securityholder, who shall bear all of the liability related thereto), indemnities or other agreements made in connection with the Transfer.  Each Securityholder will bear (x) its or his or her own costs of any sale of Securities pursuant to this Section 4.1(a) and (y) its or his or her pro-rata share (based upon the relative amount of Securities sold) of the costs of any sale of Securities pursuant to this Section 4.1(a) (excluding all amounts paid to any Securityholder or his or its Affiliates as a transaction fee, broker’s fee, finder’s fee, advisory fee, success fee, or other similar fee or charge related to the consummation of such sale) to the extent such costs are incurred for the benefit of all Securityholders and are not otherwise paid by the Transferee.

If none of the Other Holders gives the Selling Holder a timely Tag-Along Notice with respect to the Transfer proposed in the Sale Notice, then (notwithstanding the first sentence of this Section 4.1(a)) the Selling Holder may, subject to the terms and conditions of the Holdings LLC Agreement and applicable law, Transfer such Offered Securities on the terms and conditions set forth, and to or among any of the Transferees identified (or Affiliates of Transferees identified), in the Sale Notice at any time within ninety (90) days after expiration of the fifteen-day period for giving Tag-Along Notices with respect to such Transfer.  Any such Offered Securities not Transferred by the Selling Holder during such ninety-day period will again be subject to the provisions of this Section 4.1(a) upon subsequent Transfer.  If one or more Other Holders give the Selling Holder a timely Tag-Along Notice, then the Selling Holder shall use all reasonable efforts to obtain the agreement of the prospective Transferee(s) to the participation of the Other Holders in any contemplated Transfer, on the same terms and conditions as are applicable to the Offered Securities, and no Selling Holder shall transfer any of its Securities to any prospective Transferee if such prospective Transferee(s) declines to allow the participation of the Other Holders.  If the prospective Transferee(s) is unwilling or unable to acquire all of the Offered Securities specified in a timely Tag-Along Notice upon such terms, then the Selling Holder may elect either to cancel such proposed Transfer or to allocate the maximum number of each class of Securities that the prospective Transferees are willing to purchase (the “Allocable Securities”) among the Selling Holder and the Other Holders giving timely Tag-Along Notices as follows (it being understood that the prospective Transferees shall be required to purchase Securities of the same class on the same terms and conditions taking into account the provisions of clause (1) of the first paragraph of this Section 4.1(a), whether or not they are represented by voting trust certificates, and to consummate such Transfer on those terms and conditions):

(i)            each participating Securityholder (including the Selling Holder) shall be entitled to sell a number of shares of each class of Securities (taking into account the provisions of clause (1) of the first paragraph of this Section 4.1(a)) (not to exceed,

6

for any Other Holder, the number of shares of such class of Securities identified in such Other Holder’s Tag-Along Notice) equal to the product of (A) the number of Allocable Securities of such class of Securities and (B) a fraction, the numerator of which is such Securityholder’s Ownership Percentage of such class of Securities and the denominator of which is the aggregate Ownership Percentage for all participating Securityholders of such class of Securities; and

(ii)           if after allocating the Allocable Securities of any class of Securities to such Securityholders in accordance with clause (i) above, there are any Allocable Securities of such class that remain unallocated, then they shall be allocated (in one or more successive allocations on the basis of the allocation method specified in clause (i) above) among the Selling Holder and each such Other Holder that has elected in its Tag-Along Notice to sell a greater number of shares of such class of Securities than previously has been allocated to it pursuant to clause (i) and this clause (ii) (all of whom (but no others) shall, for purposes of clause (i) above, be deemed to be the participating Securityholders) until all such Allocable Securities have been allocated in accordance with this clause (ii).

(b)           Excluded Transfers.  The rights and restrictions contained in Section 4.1(a) shall not apply with respect to any of the following Transfers of Securities:

(i)            any Transfer of Vestar Securities in a Public Sale;

(ii)           any Transfer of Vestar Securities to and among the members or partners of Vestar and the members, partners, securityholders and employees of such partners (subject to compliance with Sections 4.3 and 4.4 hereof);

(iii)          any Transfer of Vestar Securities in accordance with Section 5.1;

(iv)          any Transfer of Vestar Securities incidental to the exercise, conversion or exchange of such securities in accordance with their terms or any reclassification or combination of shares (including any reverse stock split);

(v)           any Transfer of Vestar Securities to employees or directors of, or consultants to, any of the Holdings and its Subsidiaries;

(vi)          any Transfer constituting an Exempt Individual Transfer;

(vii)         any Transfer of Securities pursuant to the Exchange Agreement; and

(viii)        any Transfer of Securities to the Corporation, Holdings or any of the their respective Subsidiaries if such Transfer is funded by the sale of Voting Securities by the Corporation, Holding or any of their respective Subsidiaries.

(c)           Excluded Securities.  No Securityholder shall be entitled to exercise any rights as an Other Holder under Section 4.1(a) with respect to Securities that have been transferred by the Selling Holder or an Other Holder in a Transfer pursuant to the provisions of

7

Section 4.1(a) (“Excluded Securities”), and no Excluded Securities held by a Selling Holder or any Other Holder shall be counted in determining the respective participation rights of such Holders in a Transfer subject to Section 4.1(a).

4.2           Securities Act Compliance  No Voting Securities may be Transferred by a Securityholder (other than pursuant to an effective registration statement under the Securities Act) unless such Securityholder first delivers to the Corporation an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to the Holdings, to the effect that such Transfer is not required to be registered under the Securities Act.  No Holdings Interests may be Transferred by a Securityholder other than in compliance with the terms of the Holdings LLC Agreement.

4.3           Certain Transferees Bound by Agreement. Each Securityholder hereby agrees that it shall, prior to any Transfer by such Securityholder of Securities that is not to be made (a) pursuant to an offering registered under the Securities Act (a “Public Offering”) , or to the public through a broker, dealer or market-maker pursuant to Rule 144 promulgated thereunder (a “Rule 144 Sale”) or (b) in a transaction that will result in the termination of this Agreement, deliver to the Corporation and to Holdings a written agreement of the proposed Transferee to become a Securityholder and to be bound by the terms of this Agreement; provided that the foregoing agreement shall not apply in respect of Transfers of Voting Securities and/or Holdings Interests to a limited partner of Vestar (excluding any such limited partner who is an employee either of the general partner of Vestar or an Affiliate of the general partner of Vestar).  All Park Avenue Securities and Other Investor Securities will continue to be Park Avenue Securities or Other Investor Securities, as the case may be, in the hands of any Transferee (other than the Corporation, Holdings or any of their Subsidiaries, Vestar or any Transferee in a Public Sale).  All Vestar Securities will continue to be Vestar Securities in the hands of any Transferee (other than the Corporation, Holdings or any of their Subsidiaries, Park Avenue, Other Investors or a Transferee in a Public Sale).

4.4           Transfers in Violation of Agreement. Any Transfer or attempted Transfer of any Securities in violation of any provision of this Agreement shall be void, and neither the Corporation nor Holdings shall record any such Transfer on its books or treat any purported transferee of such securities as the owner thereof for any purpose.

8

without their actual consent.  Without limiting the foregoing, (i) if the proposed Sale of DynaVox is structured as a sale of assets or a merger or consolidation, or otherwise requires equityholder approval, the Securityholders will vote or cause to be voted all Securities that they hold or with respect to which such Securityholder has the power to direct the voting and which are entitled to vote on such transaction in favor of such transaction and will waive any appraisal rights which they may have in connection therewith, and (ii) if the proposed Sale of DynaVox is structured as or involves a sale or redemption of Securities, the Securityholders will agree to sell their pro-rata share of the Securities being sold in such Sale of DynaVox on the terms and conditions approved by Vestar, and the Securityholders will execute any merger, asset purchase, security purchase, recapitalization or other sale agreement approved by Vestar in connection with such Sale of DynaVox.

(ii)           such Securityholder shall be  given the ability to exercise his or its  rights pursuant to the Exchange Agreement prior to the consummation of the Sale, and to receive in connection with such Sale the consideration which would be received on account of the Securities issuable pursuant to such exchange pursuant to the Exchange Agreement;

(iii)          any representations and warranties to be made by such Securityholder in connection with the Sale of DynaVox shall be limited to representations and warranties related to authority, ownership and the ability to convey title to such Securities and no Securityholder shall be liable for the inaccuracy of any representation or warranty made by any other Person in connection with the Sale of DynaVox, other than representations and warranties by or in respect of the Corporation and/or Holdings;

(iv)          the liability for indemnification, if any, of such Securityholder in the Sale of DynaVox and for the inaccuracy of any representations and warranties made by or in respect of  the Corporation or Holdings in connection with such Sale of DynaVox, is several and not joint with any other Person (except to the extent that funds may be paid out of an escrow established to cover breach), and is pro rata in proportion to the amount of consideration paid to such Securityholder in connection with such Sale of DynaVox;  and

(v)           the liability for indemnification shall be limited to such Securityholder’s applicable share (determined  based on the respective proceeds payable to each Securityholder in connection with such Sale of DynaVox) of a negotiated aggregate indemnification amount that applies equally to all Securityholders but that in

9

no event exceeds the amount of consideration otherwise payable to such Securityholder in connection with such Sale of DynaVox, except with respect to claims related to fraud or breaches of representations or warranties by such Securityholder, the liability for which need not be limited as to such Securityholder;

(c)           Each Securityholder will bear its or his pro-rata share (based upon the relative amount of Securities sold) of the reasonable costs of any sale of Securities pursuant to a Sale of DynaVox to the extent such costs are incurred for the benefit of all Securityholders and are not otherwise paid by the Corporation, Holdings or the acquiring party.  Costs incurred by or on behalf of a Securityholder for its or his sole benefit will not be considered costs of the transaction hereunder.  In the event that any transaction that Vestar elects to consummate or cause to be consummated pursuant to this Section 5.1 is not consummated for any reason, Holdings will reimburse Vestar for all actual and reasonable expenses paid or incurred by Vestar in connection therewith.

(d)           Notwithstanding any provision in this Agreement to the contrary, Vestar and Park Avenue and/or their Affiliates shall be entitled to be paid customary and reasonable fees by the Corporation and/or Holdings for any investment banking services provided by them in connection with a Sale of DynaVox.
