NOW, THEREFORE, in consideration of the foregoing and the mutual premises, representations, warranties, covenants and agreements contained herein, the parties hereto, intending to be legally bound, hereby agree as follows:

Section 1.1 Capitalized Terms. For purposes of this Agreement, capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

(a) “Affiliate” means, with respect to any specified Person, any Person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the Person specified. For purposes of this Agreement, with respect to each Stockholder, the term “Affiliate” shall not include the Company and the Persons that directly, or indirectly through one or more intermediaries, are controlled by the Company.

(b) “Representative” means, with respect to any particular Person, any director, officer, employee, accountant, consultant, legal counsel, investment banker, advisor, agent or other representatives of such Person.

(c) “Subject Shares” means, with respect to any particular Stockholder, (i) the number of shares of common stock, par value $0.01 per share (the “Common Stock”), of the Company set forth opposite such Stockholder’s name on Schedule I hereto, including any other shares of Common Stock the voting power over which is acquired by such Stockholder during the period from and including the date hereof through and including the date on which this Agreement is terminated in accordance with its terms and (ii) any securities into which or for which any or all of the Subject Shares may be changed or exchanged or which are received as a result of any stock dividend or distribution, split-up, recapitalization, combination, exchange of shares or the like.

Section 2.1 Agreement to Vote the Subject Shares. Each Stockholder, in its capacity as such, hereby agrees that, during the period commencing on the date hereof and continuing until the termination of this Agreement (such period, the “Voting Period”), at any meeting (or any adjournment or postponement thereof) of the Company’s stockholders, however called, or in connection with any written consent of the Company’s stockholders, such Stockholder shall vote (or cause its controlled Affiliates to vote) the Subject Shares (x) in favor of the adoption of the Merger Agreement, the Merger and the other transactions contemplated by the Merger Agreement (and any actions required in furtherance thereof), (y) against any action, proposal, transaction or agreement that would result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, and (z) except with the written consent of Toppan, against the following actions or proposals (other than the transactions contemplated by the Merger Agreement): (i) any Takeover Proposal; and (ii) (A) any change in the board of directors of the Company; (B) any amendment of the Company’s certificate of incorporation or bylaws; or (C) any other action or proposal involving the Company or any of its Subsidiaries that, in the case of (A), (B) or (C), is intended, or could reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect the transactions contemplated by the Merger Agreement; provided, however, that nothing in this Agreement shall limit or affect any actions taken by any member of the board of directors of the Company nominated by, or appointed at the request of, any Stockholder solely in his or her capacity as a director of the Company. Any such vote shall be cast or consent shall be given in accordance with such procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent. Each Stockholder agrees not to enter into any agreement or commitment with any Person the effect of which would be inconsistent with or violative of the provisions and agreements contained in this Article II.

Section 2.2 Grant of Irrevocable Proxy. Each Stockholder hereby appoints any officer of Toppan and any designee of Toppan, and each of them individually, as such Stockholder’s proxy

and attorney-in-fact, with full power of substitution and re-substitution, to vote or act by written consent during the Voting Period with respect the Subject Shares in accordance with Section 2.1. This proxy is given to secure the performance of the duties of each Stockholder under this Agreement. Each Stockholder shall promptly cause a copy of this Agreement to be deposited with the Company at its principal place of business. Each Stockholder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy.

Section 2.3 Nature of Irrevocable Proxy. The proxy and power of attorney granted pursuant to Section 2.2 by each Stockholder shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by such Stockholder with respect to the subject matter contemplated by Section 2.1.

(b) No Exercise of Registration Rights. Each Stockholder agrees that it shall not, and it shall cause its controlled Affiliates not to, directly or indirectly, exercise any registration rights with respect to the Subject Shares, including, without limitation, the registration rights set forth that certain Registration Rights Agreement, dated December 31, 1995, by and among the Company and DCEO.
