Contribution Agreement
(Toshiba)

against any and all Losses arising out of or resulting from (a) the failure of any of Toshiba’s representations or warranties contained in this Agreement or the certificates to be delivered at Closing to be true and correct and (b) the failure of Toshiba to perform any of its covenants or obligations under this Agreement.

6.4 Indemnifications by the Company. Subject to the other terms of this Article VI, the Company shall indemnify, defend and hold harmless Toshiba and its directors, officers, employees, successors, assigns, and representatives (collectively, the “Contributing Parties”) from and against any and all Losses arising out of or resulting from (a) the failure of any of the Company’s representations or warranties contained in this Agreement or the certificates to be delivered at Closing to be true and correct or (b) the failure of the Company to perform any of its covenants or obligations under this Agreement.

6.5 Indemnification Procedure.

(a)

Promptly following receipt by either the Company Parties or the Contributing Parties (each an “Indemnified Party”) of notice by a third party (including any Governmental Authority) of any complaint or the commencement of any audit, investigation, action or proceeding (in each case, a “Claim”) with respect to which such Indemnified Party may be entitled to receive payment from the other Party for any Loss, such Indemnified Party shall notify Toshiba or the Company, as the case may be (the “Indemnifying Party”); provided, however, that the failure to so notify the Indemnifying Party shall relieve the Indemnifying Party from liability hereunder with respect to such Claim only if, and only to the extent that, such failure to so notify the Indemnifying Party results in the loss by the Indemnifying Party of (or other limitations to) rights and defenses otherwise available to the Indemnifying Party or the Indemnified Party with respect to such Claim. The Indemnifying Party shall have the right, upon written notice delivered to the Indemnified Party within twenty (20) days thereafter, to assume the defense of such Claim (which may be with a reservation of rights to deny liability under an indemnity), including the employment of counsel hired in consultation with the Indemnified Party (“Litigation Counsel”) and the payment of the fees and disbursements of such Litigation Counsel and other costs of such defense. In the event, however, that the Indemnifying Party declines or fails to assume the defense of such Claim as provided above or to employ Litigation Counsel, in either case within such twenty (20) day period, then such Indemnified Party may employ counsel to represent or defend the Indemnified Party in any such Claim, and the Indemnifying Party shall promptly reimburse the Indemnified Party for all reasonable fees and disbursements of such counsel and other reasonable costs of such defense (which reimbursement obligation shall accrue from the first dollar of such costs as incurred by the Indemnified Party). In any event, the Indemnifying Party shall not be required to pay the fees and disbursements

Contribution Agreement
(Toshiba)

			of more than one counsel for all Indemnified Parties in any jurisdiction in connection with such Claim, unless Litigation Counsel determines that continued representation of the Indemnified Party is inappropriate due to a conflict of interest under applicable ethical rules resulting from its representation of both the Indemnifying Party and such Indemnified Party, in which case, the Indemnifying Party shall have the option of (i) appointing substitute counsel that does not believe it is subject to such a conflict of interest or (ii) employing and paying the fees and disbursements of different counsel to represent such Indemnified Party. Notwithstanding the Indemnifying Party’s election to assume the defense of any third party Claim, the Indemnified Party shall have the right at its cost to employ separate counsel (including local counsel) to monitor (but not control) such defense. The Indemnifying Party or the Indemnified Party (as the case may be) shall at all times use commercially reasonable efforts to keep the Indemnifying Party or Indemnified Party (as the case may be) reasonably apprised of the status of the defense of any matter the defense of which it is maintaining and to cooperate in good faith with each other with respect to the defense of any such matter.

	(b)		No Indemnified Party may settle or compromise any Claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder without the prior written consent of the Indemnifying Party, unless (i) the Indemnifying Party fails to assume and maintain the defense of such Claim pursuant to Section 6.5(a), (ii) such settlement, compromise or consent does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnifying Party and (iii) such settlement, compromise or consent includes an unconditional release of the Indemnifying Party and its directors, officers, employees, successors, assigns and representatives from all liability arising out of such Claim. An Indemnifying Party may not, without the prior written consent of the Indemnified Party, settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder unless such settlement, compromise or consent (x) includes an unconditional release of the Indemnified Party and its directors, officers, employees, successors, assigns and representatives from all liability arising out of such Claim, (y) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnified Party and (z) does not contain any equitable order, judgment or term that in any material manner affects, restrains or interferes with the business of the Indemnified Party or any of the Indemnified Party’s Affiliates.

	(c)		If an Indemnified Party claims a right to payment pursuant hereto, such Indemnified Party shall send written notice of such Claim to the appropriate Indemnifying Party. Such notice shall specify the basis for

Contribution Agreement
(Toshiba)

such Claim. The failure by any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party with respect to any Claim made pursuant to this Section 6.5(c). If the Indemnifying Party agrees it is liable for such Claim, it shall pay the amount of such liability to the Indemnified Party **, or, in the case of any notice in which the amount of the Claim (or any portion of the Claim) is estimated, ** after such later date when the amount of such Claim (or such portion of such Claim) becomes finally determined. In the event the Indemnifying Party does not respond to such Claim or disputes its liability with respect to such Claim, such Indemnified Party and the appropriate Indemnifying Party shall, as promptly as possible, establish the merits and amount of such Claim by making good faith efforts to come to an agreement or, failing^** mutual agreement, by the exercise of such legal remedies as may be available, subject to Sections 6.6, 6.7 and 6.8.

6.6 Liability Limits. Except as expressly provided in the third sentence of Section 6.5(a), notwithstanding anything to the contrary set forth herein, in no event shall there be any liability under Section 6.3(a) or 6.4(a) until the aggregate amount of all Losses suffered arising from matters covered by the indemnity contained such Section exceeds ** (the “Basket Amount”). In no event shall any Company Party or Contributing Party be entitled to assert a claim under Section 6.3(a) or 6.4(a) (as applicable) unless such Claim is submitted in compliance with the other procedures of Section 6.5. The liability of the Indemnifying Party under Section 6.3(a) or 6.4(a) shall not exceed ** No claim for indemnification may be made under Section 6.3(a) or 6.4(a) if the Indemnified Party making the claim had actual knowledge of such breach prior to Closing and elected to consummate the Closing. In determining the amount of any Losses entitled to indemnification under Article VI, the gross amount thereof will be reduced by any insurance proceeds actually received by the claimant with respect to such Losses (net of any related deductibles and self insurance amounts).

6.7 Exclusive Remedy. Notwithstanding any other provision of this Agreement to the contrary or any remedies that might otherwise be available under Law (other than claims based on fraud), the remedies set forth in this Article VI and the specific performance remedy referenced in Section 7.11 shall constitute the sole and exclusive remedies of the Parties hereto (or any assignee of a Party to which conveyance is made as contemplated in connection herewith) for any claims arising under this Agreement, the certificates or any other documents executed pursuant to this Agreement to be delivered at Closing.

6.8 Consequential Damages. NOTWITHSTANDING ANY PROVISION OF THIS AGREEMENT, IN NO EVENT SHALL ANY PARTY EVER BE LIABLE TO ANY OTHER PARTY OR THIRD PARTY WITH RESPECT TO ANY CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT FOR ANY LOST OR PROSPECTIVE PROFITS OR ANY OTHER SPECIAL, PUNITIVE, EXEMPLARY, CONSEQUENTIAL, INCIDENTAL, OR INDIRECT LOSSES OR DAMAGES FROM ITS PERFORMANCE UNDER THIS AGREEMENT

OR FOR ANY FAILURE OR PERFORMANCE HEREUNDER OR RELATED HERETO, WHETHER ARISING OUT OF BREACH OF CONTRACT, NEGLIGENCE, TORT, STRICT LIABILITY, OR OTHERWISE AND WHETHER OR NOT ARISING FROM ANY OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT.

6.9 Termination. This Agreement may be terminated:

	(a)		by mutual consent in writing of the Parties;

	(b)		automatically if a notice is given pursuant to Section 3.4(b) or such notice is deemed to have been given;

	(c)		by Toshiba at any time on or prior to the date that is 31 calendar days after the Effective Date for any reason or no reason, and in its sole and absolute discretion;

	(d)		by written notice by any Party to the other Party, as the case may be, in the event the matters described in Section 3.2(m) have not been agreed in writing on or prior to May 2, 2008; and

	(e)		by written notice by any Party to the other Party, as the case may be, in the event the Closing has not occurred on or prior to ** (but such termination shall not relieve a Party of any default under this Agreement arising prior thereto).

7.6 Entire Agreement. This Agreement, the other Transaction Documents, the attached schedules and exhibits and the agreements and documents to be executed pursuant to this Agreement constitute the entire agreement between the Parties as of the date of this Agreement and supersede any prior understandings, agreements, or representations by or between the Parties, written or oral, to the extent they have related in any way to the subject matter hereof.

	(a)		Each Party hereby agrees that any dispute, controversy or claim between the Parties arises under this Agreement or is connected with or related in any way to this Agreement or any right, duty or obligation arising hereunder or the relationship of the Parties hereunder may be so submitted to binding arbitration hereunder and pursuant to the procedures set forth in Exhibit C, and if so submitted, shall be resolved exclusively and finally through such binding arbitration. This Section 7.8 and Exhibit C constitute a written agreement by the Parties to submit to arbitration any Dispute arising under or in connection with this Agreement within the meaning of the Federal Arbitration Act, 9 U.S.C. §§ 1, et. seq.

	(b)		Prior to the appointment of the arbitration tribunal, either Party may seek provisional relief, including provisional injunctive relief, from any court of competent jurisdiction, and the application for such relief shall not be deemed inconsistent with, or a waiver of, the right to arbitrate the Dispute. With respect to any such application for provisional relief, the Parties irrevocably submit to the personal jurisdiction of the state and federal courts located in Washington, D.C., and waive objection to venue. Once the arbitration tribunal is appointed, all subsequent applications for provisional relief shall be made to the arbitration tribunal.

In such event, the Parties hereto agree and consent that such provisions and this Agreement shall be modified and reformed so as to effect the original intent of the Parties as closely as possible with respect to those provisions which were held to be invalid or unenforceable.

7.10 Counterparts. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which shall constitute but one agreement.

7.11 Remedies. Each Party acknowledges that the remedies at law of the Parties for a breach or threatened breach of this Agreement would be inadequate and, in recognition of this fact, either Party, without posting any bond, and in addition to all other remedies that may be available, shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy that may then be available. Notwithstanding Section 7.8, either Party may seek a temporary restraining order or preliminary injunction from a court of competent jurisdiction pending mediation or arbitration.

Arbitration Procedures

1.1 Disputes. Any and all claims, counterclaims, demands, causes of action, disputes, controversies, and other matters in question arising out of or relating to this Agreement, or to the alleged breach hereof, or in any way relating to the subject matter of this Agreement or the relationship between the Parties created by this Agreement (whether extra-contractual in nature, sounding in contract, tort or otherwise, or provided for by federal or state statute, common law or otherwise) (hereafter a “Dispute”) shall be finally resolved by binding arbitration under the Non-Administered Arbitration Rules of the International Institute for Conflict Prevention and Resolution (the “Rules”) then in force to the extent such Rules are not inconsistent with the provisions of this Agreement.

1.2 Negotiation to Resolve Disputes. If a Dispute arises out of or relates to this Agreement, a Party may give notice to all other Parties that it intends to initiate the dispute resolution procedures set forth herein. Promptly upon receipt of such notice, each Party that is a party to the Dispute (each, a “Disputing Party”) shall refer such Dispute to a senior executive officer (“SEO”) of each Disputing Party (or of Toshiba’s Power Systems Company, in the case of Toshiba). The SEOs will meet in person or by teleconference as soon as mutually practicable in order to try and resolve the Dispute. If the SEOs are unable to resolve the Dispute on or before the 30^th Day after such notice, any Disputing Party may commence an arbitration under this Appendix B by notifying each Party (an “Arbitration Notice”).

1.3 Selection of Arbitrators.

(a) Three Arbitrators. Any arbitration conducted under this Appendix B shall be heard by three arbitrators (each an “Arbitrator” and collectively the “Tribunal”) selected in accordance with this Section 1.3. Each Disputing Party and any proposed Arbitrator shall, as soon as practicable, disclose to the other Disputing Parties any business, personal or other relationship or affiliation that may exist between any Party and the proposed Arbitrators. The Disputing Parties may then object to any of the proposed Arbitrators on the basis of such relationship or affiliation. The validity of any such objection shall be determined according to the Rules.

(b) Selection of Arbitrators. Except as provided for in this Section 1.3, the Tribunal shall be appointed according to the Rules. In the Arbitration Notice, the Disputing Party requesting arbitration shall nominate one Arbitrator. The Disputing Party named as respondent by the claimant shall nominate one Arbitrator. Within 30 Days of the appointment of the second Arbitrator, the two party-appointed Arbitrators shall appoint a third Arbitrator who shall chair the arbitration. Where the Dispute at issue involves more than two Disputing Parties, the International Institute for Conflict Prevention and Resolution (“CPR”) shall provide a list of potential Arbitrators. Within seven (7) days of receiving this list, each Disputing Party shall provide to CPR a ranking of the potential Arbitrators on such list showing such Disputing Party’s order of preference among such proposed Arbitrators, with any one or more Disputing Parties who are Affiliates of one another submitting one common ranked list. The CPR shall then

appoint all three Arbitrators as it shall determine in its discretion but taking into account to the extent practical the Disputing Parties’ preferences.

1.4 Conduct of Arbitration. The Tribunal shall expeditiously (and, if practicable, consistent with the Tribunal’s primary responsibility to justly adjudicate the dispute before it, within 180 Days after the appointment of the third Arbitrator) hear and decide all matters concerning the Dispute. Any arbitration hearing shall be held in Washington, D.C. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§1 et. seq. Except as expressly provided to the contrary in this Agreement, the Tribunal shall have the power to gather such materials, information, testimony and evidence as it deems relevant to the dispute before it (and each Party will provide such materials, information, testimony and evidence requested by the Tribunal, subject to such protective orders as the Tribunal determines necessary for the protection of any information so requested that is proprietary, subject to a third-party confidentiality restriction or to an attorney-client or other privilege) and to grant injunctive relief and enforce specific performance. The Tribunal shall not have the power to award punitive or any other form of indirect or non-compensatory damages, even if such are available under the governing law and even if a court would otherwise be empowered to avoid this limitation on damages to make such an award. If it deems necessary, the Tribunal may propose to the Disputing Parties that one or more other experts be retained to assist it in resolving the Dispute. The retention of such other experts shall require the unanimous consent of the Disputing Parties, which shall not be unreasonably withheld. The decision of the Tribunal (which shall be rendered in writing) shall be final, nonappealable and binding upon the Parties and may be enforced in any court of competent jurisdiction. Each Party hereby consents to the non-exclusive personal jurisdiction and venue of the Washington D.C. courts for any proceedings in aid of arbitration under this Section, including any request for interim or injunctive relief. Notwithstanding the foregoing consent, the Parties may nevertheless seek interim or injunctive relief from any court of competent jurisdiction.

1.5 Arbitration Costs and Expenses. The responsibility for paying the costs and expenses of the arbitration, including compensation to the Tribunal and any experts retained by the Tribunal, shall be borne by the Disputing Party or Disputing Parties who is or are the least successful in such process, which shall be determined by the Tribunal by comparing the position asserted by each Disputing Party on all disputed matters taken together to the final decision of the Tribunal on all disputed matters taken together, provided however, that each Disputing Party shall be responsible for the fees and expenses of its respective counsel, consultants and witnesses, unless the Tribunal determines that compelling reasons exist for allocating all or a portion of such costs and expenses to the other Disputing Parties.
