5. Representations and Warranties of the Shareholder. The Shareholder hereby represents and warrants to Quantum as follows:

(a) The Shareholder is the sole record owner and beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good, valid and marketable title to, or has a valid proxy to vote, the Shareholder’s Covered Shares, free and clear of any Liens (other than as created by this Agreement or the Governing Documents of the Company). As of the date hereof, other than the Covered Shares set forth opposite the Shareholder’s name on Schedule 1, the Shareholder does not own beneficially or of record any shares of Company Stock (or any securities convertible into shares of Company Stock) or any interest therein.

(b) The Shareholder, except as provided in this Agreement or the Governing Documents of the Company, (i) has full voting power, full power of disposition and full power to issue instructions with respect to the matters set forth herein, whether by ownership or by proxy, in each case, with respect to the Shareholder’s Covered Shares, (ii) has not entered into any voting agreement or voting trust, and has no knowledge and is not aware of any such voting agreement or voting trust in effect with respect to any of the Shareholder’s Covered Shares, that is inconsistent with the Shareholder’s obligations pursuant to this Agreement, (iii) has not granted a proxy or power of attorney with respect to any of the Shareholder’s Covered Shares that is inconsistent with the Shareholder’s obligations pursuant to this Agreement, and has no knowledge and is not aware of any such proxy or power of attorney in effect, and (iv) has not entered into any agreement or undertaking that is otherwise inconsistent with, or would interfere with, or prohibit or prevent it from satisfying, its obligations pursuant to this Agreement, and has no knowledge and is not aware of any such agreement or undertaking.

(c) The Shareholder affirms that it (A) is a legal entity duly organized, validly existing and, to the extent such concept is applicable, in good standing under the Laws of the jurisdiction of its organization and (B) has all requisite corporate or other power and authority to, and has taken all corporate or other action necessary in order to, execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby. This Agreement has been duly executed and delivered by the Shareholder and, subject to the due execution and delivery of this Agreement by each of the Company and Quantum, constitutes a legally valid and binding agreement of the Shareholder enforceable against the Shareholder in accordance with the terms hereof (except as enforceability may be limited by bankruptcy Laws or other similar Laws affecting creditors’ rights and general principles of equity affecting the availability of specific performance and other equitable remedies).

(d) Other than the filings, notices and reports pursuant to, in compliance with or required to be made under the Exchange Act and the Financial Instruments and Exchange Act of Japan (Act No. 25 of April 13, 1948, as amended), no filings, notices, reports, consents, registrations, approvals, permits, waivers, expirations of waiting periods or authorizations are required to be obtained by the Shareholder from, or to be given by the Shareholder to, or to be made by the Shareholder with, any Governmental Authority in connection with the execution, delivery and performance by the Shareholder of this Agreement, the consummation of the transactions contemplated hereby or the Transactions.

(e) The execution, delivery and performance of this Agreement by the Shareholder does not, and the consummation of the transactions contemplated hereby and the Transactions will not, constitute or result in (i) a breach or violation of, or a default under, the Governing Documents of the Shareholder, (ii) a breach or violation of, a termination (or right of termination) of or a default under, the loss of any benefit under, the creation, modification or acceleration of any obligations under or the creation of a Lien on any of the properties, rights or assets of the Shareholder pursuant to any Contract binding upon the Shareholder or, assuming (solely with respect to performance of this Agreement and the transactions contemplated hereby), compliance with the matters referred to in Section 5(d), under any applicable Law to which the Shareholder is subject, (iii) any change in the rights or obligations of any party under any Contract legally binding upon the Shareholder or (iv) any violation of applicable Law, except, in the case of clauses (ii), (iii) or (iv) directly above, for any such breach, violation, termination, default, creation, acceleration or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay or impair the Shareholder’s ability to perform its obligations hereunder or to consummate the transactions contemplated hereby or the Transactions.

(f) As of the date of this Agreement, there is no Action pending against the Shareholder or, to the knowledge of the Shareholder, threatened against the Shareholder that, in any manner, questions the beneficial or record ownership of the Shareholder’s Covered Shares or the validity of this Agreement, or challenges or seeks to prevent, enjoin or materially delay the performance by the Shareholder of its obligations under this Agreement.

(a) This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the internal Laws of the State of Delaware, including its statute of limitations, without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of the Laws or statute of limitations of another jurisdiction.

(b) Any Action based upon, arising out of or related to this Agreement or the transactions contemplated hereby may only be brought in the Court of Chancery of the State of Delaware or, if such court lacks jurisdiction, the state and federal courts in the State of Delaware, and each of the Parties irrevocably submits to the exclusive jurisdiction of each such court in any such Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Action shall be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any other court.

Neither this Agreement nor any of the rights, interests or obligations hereunder shall (a) be assigned by any of the Shareholder, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of Quantum and the Company or (b) be assigned by Quantum or the Company, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the Company (in the case of an attempted assignment by Quantum) or Quantum (in the case of an attempted assignment by the Company). Any such assignment without such consent shall be null and void. This Agreement shall be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

18. Enforcement. The Parties agree that irreparable damage (for which monetary damages, even if available, would not be an adequate remedy) would occur, and that the Parties would not have any adequate remedy at law, in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to specific performance, an injunction or injunctions, or other equitable relief to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, including the Company’s obligations under Section 1 and the Shareholder’s obligations under Section 2, without proof of actual damages or otherwise (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at Law or in equity. Each Party acknowledges and agrees that the right of specific enforcement is an integral part of the transactions contemplated hereby and that, without such right, none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other Parties have an adequate remedy at Law. In the event of a final non-appealable judgement from a court of competent jurisdiction relating to this Agreement, the prevailing party in such action shall be entitled to reasonable and documented fees and expenses (including reasonable and documented attorney’s fees) from the non-prevailing party.

19. Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms and provisions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

10

20. Counterparts.
