     NOW, THEREFORE, the Parties, in consideration of the premises and the terms, covenants and conditions set forth below, hereby agree as follows:

AGREEMENT

1. DEFINITIONS; INTERPRETATION.

     1.1 Terms Not Defined in this Agreement. Term used but not otherwise defined herein shall have the meanings given to such terms in the Put Option Agreement.

     1.2 Interpretation.

     (a) Certain Terms. The words “hereof,” “herein,” “hereunder” and similar words refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “including” is not limited and means “including without limitation.”

     (b) Section References; Titles and Subtitles. Unless otherwise noted, all references to Sections herein are to Sections of this Agreement. The titles, captions and headings of this Agreement are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.

2. REIMBURSEMENT OBLIGATION.

     2.1 Reimbursement by Shaw. (a) If and to the extent that, (i) in connection with the transfer of Shares pursuant to the Put Option Agreements, Toshiba or its subsidiaries are required to pay any stamp duty, stamp duty reserve tax, transfer tax or other similar tax or duty (“Transfer Taxes”) or (ii) in accordance with Section 3.2 either of the Put Option Agreement, Toshiba (or its permitted designee under a Put Option Agreement) (A) is required under applicable law to withhold or deduct from the Put Price any taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or within Japan or any authority therein or thereof having power to tax (“Taxes”) and (B) pays to NEH any additional amounts as will result in the receipt by NEH of such amounts as would have been received by NEH had no withholding or deduction been required (“Tax Gross-Up Amounts”), Shaw shall reimburse Toshiba for (x) all such Tax Gross-Up Amounts, (y) all such Transfer Taxes and (z) additional Taxes paid or payable by Toshiba in respect of the amounts reimbursed under the preceding clauses (x) and (y) (collectively, the “Put Loss Amounts”) within two Business Days after receipt from Toshiba of a written request for payment thereof (together with substantiating documentation).

     (b) In addition, Shaw agrees to pay on demand any and all costs, including reasonable legal fees and expenses, and other expenses incurred by Toshiba in enforcing Shaw’s payment obligations under this Section 2.1; provided that Shaw shall not be liable for any such costs and expenses if no payment under this Section 2.1 is due (such amounts, together with the Put Loss Amounts, the “Reimbursable Amounts”).

     2.2 Nature of Obligations. The obligations of Shaw hereunder are primary and unconditional, and Toshiba shall not be required to bring an action against NEH to enforce its rights against Shaw with respect to any Reimbursable Amounts. Until payment in full of Reimbursable Amounts, Shaw expressly waives, on behalf of itself and NEH, any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which Shaw or NEH may now or hereafter have against Toshiba arising from the existence or performance of this Agreement or any other agreement.

     2.3 Dividend. Upon receipt by Shaw of a written request for payment as contemplated by Section 2.1, Shaw shall cause NEH (subject to any restrictions in NEH’s financing documentation) to assign and pay over to Toshiba all Dividends that NEH receives after exercise of the Put Right up to an amount, when combined with any payments made by or on behalf of Shaw in respect of its obligations under Section 2.1, equal to the full amount of all Reimbursable Amounts (“Assigned Dividends”), and all such rights shall thereupon become

vested in Toshiba, which shall have the sole and exclusive right and authority to receive and retain any such Assigned Dividends. In such event, Shaw shall cause NEH to promptly notify (or if NEH does not do so promptly, shall allow Toshiba to notify) the applicable HoldCo and instruct such HoldCo to pay any and all such Assigned Dividends directly to Toshiba free and clear of, and without withholding or deduction for, any taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by any Government Authority having power to tax, unless such withholding or deduction is required by law. All Assigned Dividends received by Shaw or its Subsidiaries contrary to the provisions of this Section 2.3 shall be held in trust for the benefit of Toshiba, shall be segregated from other property or funds of Shaw and such Subsidiaries and upon receipt shall be forthwith delivered to Toshiba in the same form as so received (with any necessary endorsement), free and clear of, and without withholding or deduction for, any taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by any Government Authority having power to tax, unless such withholding or deduction is required by law. For the purposes of this Section 2.3, the term “Dividends” shall mean any dividends, interest, cash, instruments and other property distributed from time to time by the applicable HoldCo in respect of the Shares or any shares, interests or other securities issued or distributed by the applicable HoldCo with respect thereto.

3. RANKING, PAYMENTS AND SET-OFF.

     3.1 Ranking. The payment obligations of Shaw under this Agreement shall, save for such exceptions as may be provided in applicable bankruptcy Law, at all times rank pari passu with all of Shaw’s other present and future unsecured and unsubordinated obligations.

     3.2 Withholding. All payments made by or on behalf of Shaw under this Agreement shall be made free and clear of, and without withholding or deduction for, any taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by any Government Authority having power to tax, unless such withholding or deduction is required by law, in which event Shaw shall pay such additional amounts as will result in receipt by Toshiba of the full amount of Reimbursable Amounts it would have received had no such withholding or deduction been required.

     3.3 Set-off. Toshiba shall be absolutely entitled to receive all amounts payable in respect of this Agreement, and Shaw hereby waives, on behalf of itself and NEH, as against Toshiba, all rights of set-off or counterclaim that would or might otherwise be available to Shaw or NEH.
