The parties acknowledge and agree that any decision on the part of either party to terminate this Agreement shall be subject to the procedures set forth in Article VI.

SECTION 5.4. Effect of Termination; Survival.

(a) Upon any termination of this Agreement pursuant to Section 5.3(a) or (b) hereof, all further obligations of the parties hereunder shall terminate without any further liability of either party, except as provided in this Section 5.4(a).

(b) Upon any termination of this Agreement due to a material breach or failure to perform any of the representations, warranties, covenants or agreements of this Agreement or the Technology Transfer Agreement pursuant to Section 5.3(c)(i) hereof, the parties hereby agree that the remedies set forth in Article IX of the Technology Transfer Agreement shall govern.

(c) Upon any termination of this Agreement due to a material breach or failure to perform any of the representations, warranties, covenants or agreements of this Agreement or the Technology Transfer Agreement pursuant to Section 5.3(c)(ii), the parties hereby agree that the remedies set forth in Article IX of the Technology Transfer Agreement shall govern.

ARTICLE VI
DISPUTES AND ARBITRATION

SECTION 6.1. Efforts to Resolve by Mutual Agreement.

Any dispute, action, claim or controversy of any kind arising from or in connection with this Agreement or the relationship of the parties under this Agreement (the “Dispute”) whether based on contract, tort, common law, equity, statute, regulation, order or otherwise, shall be resolved as follows:

(a) Upon written request of either FCE or POSCO Power, the parties shall meet and attempt to resolve any such Dispute. Such meetings may take place via teleconference or videoconference.

(b) The parties shall meet as often as the parties reasonably deem necessary to discuss the problem in an effort to resolve the Dispute without the necessity of any formal proceeding.

(c) Formal proceedings for the resolution of a Dispute may not be commenced until the earlier of (i) the Parties concluding in good faith that amicable resolution through continued negotiation of the matter does not appear likely; or (ii) the expiration of a sixty (60) day period immediately following the initial request by either party to resolve the Dispute; provided, however, that this Section 6.1 will not be construed to prevent a party from instituting formal proceedings earlier to avoid the expiration of any applicable limitations period, to preserve a superior position with respect to other creditors or to seek temporary or preliminary injunctive relief.

SECTION 6.2. Arbitration. If the Parties are unable to resolve any Dispute, pursuant to Section 6.1 above and except as otherwise specified in Section 6.4, the Dispute shall be finally settled under the Rules of Arbitration (the “Rules”) of the International Chamber of Commerce (“ICC”) by three (3) arbitrators designated by the parties. Each party shall designate one arbitrator. The third arbitrator shall be designated by the two arbitrators designated by the parties. If either party fails to designate an arbitrator within thirty (30) days after the filing of the Dispute with the ICC, such arbitrator shall be appointed in the manner prescribed by the Rules. An arbitration proceeding hereunder shall be conducted in London, U.K., and shall be conducted in the English language. The decision or award of the arbitrators shall be in writing and is final and binding on both parties. The arbitration panel shall award the prevailing party its attorneys’ fees and costs, arbitration administrative fees, panel member fees and costs, and any other costs associated with the arbitration; provided, however, that if the claims or defenses are granted in part and rejected in part, the arbitration panel shall proportionately allocate between the parties those arbitration expenses in accordance with the outcomes. The arbitration panel may only award damages as provided for under the terms of this Agreement and in no event may punitive, consequential and special damages (or as otherwise specified in this Agreement, including, without limitation, Section 6.3) be awarded. In the event of any conflict between the Rules and any provision of this Agreement, this Agreement shall govern.

SECTION 6.3. Limitation on Recoverable Damages. In no event shall the measure of damages payable by either party under or in connection with this Agreement or the transactions or arrangements contemplated hereby include, nor will either party be liable for, any amounts for loss of income, profit or savings or indirect, incidental, consequential, exemplary, punitive or special damages of any party, including third parties, whether or not foreseeable, even if such party has been advised of the possibility of such damages in advance, and all such damages are expressly disclaimed. Notwithstanding anything contained herein to the contrary, the parties hereto shall be entitled to seek specific performance or injunctive relief in connection with any material breach by another party of its obligations under this Agreement.

SECTION 6.4. Specific Performance. The parties acknowledge and agree that the FCE Technology is unique and further acknowledge and agree that POSCO Power will suffer irreparable harm, which is not compensable by monetary damage, in the event the FCE Technology has not been fully transferred to POSCO Power at the time of the termination of this agreement due to a material breach by FCE of this Agreement. Accordingly, the parties agree that POSCO Power shall be entitled to an injunction or injunctions to enforce specifically the transfer of the FCE Technology to POSCO Power in accordance with Article IX of the Technology Transfer Agreement, in addition to any other remedy to which it may be entitled under this Agreement.

ARTICLE VII
CONFIDENTIALITY

This confidentiality provision supplements, but does not replace, the confidentiality provisions of the other Transaction Agreements. As used in this Agreement, the term “confidential information” means any and all trade secrets and other confidential information and know-how related directly or indirectly to a party’s business or its products and services, which is not covered by the confidentiality provisions of other Transaction Agreements. Each party shall hold each other’s confidential information in confidence and shall not use or disclose any confidential information, or permit any person to examine or copy any confidential information, regardless of the manner in which such party gained access to it, except as necessary for the performance of its obligations under this Agreement, including, without limitation, to such party’s legal advisors, financial advisors and accountants. Each party’s obligation of confidentiality with respect to confidential information supplied by the other hereunder shall not include or extend to information which: (i) at the date such information is disclosed to the recipient is generally known by or available to the public; (ii) after such information is disclosed to the recipient becomes generally known or available to the public, through no fault of the recipient; (iii) becomes available or is known to the recipient prior to the time of it being disclosed to the recipient as evidenced by the written records of the recipient and was not received directly or indirectly from the provider; (iv) became or becomes available to the recipient from an independent third party who is not bound by a confidentiality agreement with the provider; or (v) is required to be disclosed by the recipient to a third party in response to a subpoena or order of a court or an administrative agency, provided that the recipient shall inform the provider promptly so that the provider shall have an opportunity to seek a protective order and the recipient shall not interfere with the provider’s lawful efforts to obtain said protective order. POSCO Power shall use best efforts to require, as a condition precedent to any agreement with respect to the sale, lease or such similar transaction of any FCE Product or POSCO Product, the purchaser, lessor, customer or any such party of such transaction (x) to agree and (y) to use such party’s good faith efforts to cause any subsequent purchaser, lessor, customer or such similar party thereof, in each case, to be bound to confidentiality obligations substantially similar to the terms hereof.

ARTICLE VIII
INDEMNIFICATION

SECTION 8.1. Claims. This indemnification provision supplements, but does not replace, the indemnification provisions of the other Transaction Agreements. For purposes of this Agreement, “Claim” shall mean any liability, claim, suit, demand, loss, damage, judgment, and expense (including reasonable attorneys’ fees and costs and the cost of settlement), that is not covered by the indemnification provisions of other Transaction Agreements.

SECTION 8.2. Indemnification by POSCO. POSCO Power shall indemnify, defend, and hold harmless FCE and its representatives, successors and permitted assigns from and against any and all Claims made or threatened by any third party and all related losses, expenses, damages, costs and liabilities, including reasonable attorneys’ fees and expenses incurred in investigation or defense of such claims (“Damages”), to the extent such Damages relate to or arise out of (i) any breach of or any inaccuracy in any representation or warranty made by POSCO Power in this Agreement or (ii) any breach of or failure by POSCO Power to perform or comply with any of its covenants or agreements contained in this Agreement.

SECTION 8.3. Indemnification by FCE. FCE shall indemnify, defend, and hold harmless POSCO Power and its representatives, successors and permitted assigns from and against any and all Claims made or threatened by any third party and all related Damages, to the extent such Damages relate to or arise out of (i) any breach of or any inaccuracy in any representation or warranty made by FCE in this Agreement or (ii) any breach of or failure by FCE to perform or comply with any of its covenants or agreements contained in this Agreement.

SECTION 8.4. Indemnification Procedure. In the event a Claim by a third party for which indemnification may be available under this Agreement is made or filed against a party, the party against which the claim, suit or proceeding is made (the “Indemnified Party”), shall promptly notify the other party (the “Indemnifying Party”) in writing of the claim, suit or proceeding. The Indemnifying Party, within thirty (30) days, or such shorter period as is required to avoid any prejudice in the claim, suit or proceeding, after the notice, may elect to defend, compromise, or settle the third party claim, suit or proceeding at its expense. In any third party claim, suit or proceeding which the Indemnifying Party has elected to defend, compromise or settle, the Indemnifying Party shall not after the election be responsible for the expenses, including counsel fees, of the Indemnified Party but the Indemnified Party may participate therein and retain counsel at its own expense. In any third party claim, suit or proceeding the defense of which the Indemnifying Party shall have assumed, the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the matter without the consent of the Indemnifying Party and the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement affecting the Indemnified Party to the extent that the judgment or settlement involves more than the payment of money without the written consent of the Indemnified Party. The Indemnified Party shall provide to the Indemnifying Party all information, assistance and authority reasonably requested in order to evaluate any third party claim, suit or proceeding and effect any defense, compromise or settlement.

ARTICLE IX

Form of MTU Consent

February 7, 2007

Mr. Michael Bode
President and CEO
MTU CFC Solutions GmbH
81663 Munchen, Germany

Re: BOP Sub-license with POSCO Power of Korea

Dear Michael:

This letter refers to Article 2.a. of the MTU/FCE Balance of Plant (BOP) Cross License of July 16, 1998, as modified December 15, 1999 (the “BOP Cross License”). As we have discussed, FCE intends to execute a direct sub-license with POSCO Power of Korea (the “POSCO Power Sub-License”). This POSCO Power Sub-License will be on a non-exclusive basis, will comply with the terms of the existing BOP Cross License, as amended by the attached supplementary agreement, and will provide for the transfer of existing BOP Know How to POSCO Power.

Therefore, FCE requests MTU’s approval, in accordance with Article 2.a of the BOP Cross License, for FCE to enter into the POSCO Power Sub-License.

In addition, FCE proposes the attached revision to the BOP Cross License, to allow for POSCO Power to retain rights to use MTU’s existing BOP technology, regardless of any termination of the BOP Cross License, subject to continued payment of royalties by FCE to MTU, and provided that MTU shall have no rights to use any BOP technology developed by POSCO Power.

Please indicate your approval of this plan by signing both copies of this letter and the attached modification and returning one copy of each to my attention. If you need further information, please call or email.

Very truly yours,

/s/ Ross M. Levine, Esq

SUPPLEMENTARY AGREEMENT

by and between

FUEL CELL ENERGY, INC (“FCE”)

and

MTU CFC SOLUTIONS GmbH (“MTU”)

This Supplementary Agreement is made and entered into this 7^th day of February 2007 (the Effective Date) by and between FCE and MTU.

WHEREAS

FCE and MTU presently are parties to the Balance of Plant Cross-License of July 16, 1998 (the BOP Cross License), as modified on December 15, 1999.

WHEREAS

MTU and FCE wish to revise certain terms relating to rights of the Parties upon termination of the BOP Cross License

WHEREAS

FCE intends to execute a direct sub-license with POSCO Power of Korea entitled the “Technology Transfer License and Distribution Agreement dated as of February 7, 2007 (the “POSCO Power Sub-License”), which will be on a non-exclusive basis, will comply with the terms of the existing BOP Cross License, and will provide for the transfer of existing BOP Know How to POSCO Power.

THEREFORE

The parties agree as follows:

	1.		All rights of POSCO Power to use MTU’s existing (as of the date hereof) BOP Know-How to be transferred by FCE to POSCO Power under the POSCO Power Sub-License shall remain in full force and effect regardless of termination of the BOP Cross License.

	2.		FCE will continue to pay royalties to MTU for all such use by POSCO Power at the rates as agreed in the BOP Cross License as if the BOP Cross License remained in full force and effect.

	3.		It is understood that the BOP Know How being licensed to POSCO Power is based on the following definition of BOP:

			“Balance of Plant” or “BOP” shall mean all subsystems for operation and generation of electrical power by Molten Carbonate Fuel Cell Direct FuelCells (DFC) in one or more stacks and including, but not limited to, fuel pre-treatment boilers, water recovery, fuel exhaust burner, inverter, control system, utility interface and start-up and stand-by equipment. For the avoidance of doubt, BOP shall mean all components of the DFC Power Plant other than the Fuel Cell Stack Module.”

	4.		Any and all BOP Know How that FCE may obtain from POSCO Power during the course of the POSCO Power Sub-License shall be excluded from all requirements of Article V of the BOP Cross License so that FCE is not required to transfer such BOP Know How to MTU.

	5.		Any and all BOP Know How that FCE may obtain from MTU subsequent to the date hereof shall not be transferred to POSCO Power.

Except as expressly amended above, all other terms and conditions of the BOP Cross License are unchanged and remain as first written.

IN WITNESS WHEREOF, the parties hereto have caused this Supplementary Agreement to be executed in a manner binding upon them by their duly authorized officers as of the date shown below.

KOREA WAIVER AGREEMENT

This Korea Waiver Agreement (this “Agreement”) is entered into by and between Marubeni Corporation, a Japanese corporation having its principal office at 4-2 Ohtemachi-I-Chome Chiyoda-ku Tokyo 100-8088, Japan (“MC”), and FuelCell Energy, Inc., a Delaware corporation having its principal office at 3 Great Pasture Rd., Danbury, CT 06813, USA (“FCE”), as of February 9, 2007.

RECITALS

WHEREAS, FCE and MC have entered into an Alliance Agreement dated June 15, 2001, subsequently modified by Modification Agreements 1 through 3 (collectively “Distribution Agreements”), wherein FCE has granted exclusive rights to sell the fuel cell products manufactured by FCE (the “Products” or “Direct FuelCells^®” or “DFC^®”) in Japan, as well as non-exclusive right to sell the Products in Korea;

WHEREAS, FCE intends to enter into an Alliance Agreement (the “POSCO Power Alliance Agreement”) and Technology Transfer, License and Distribution Agreement (the “Technology License Agreement”) with POSCO Power, a Korean corporation (“POSCO Power”); the effective date of the POSCO Power Alliance Agreement is conditioned upon the receipt of certain third-party approvals, which date is expected to be no later than April 7, 2007;

WHEREAS, MC desires to waive, abandon, release, and relinquish its rights to sell or distribute the Products in Korea as granted in Article 2.1 of the Distribution Agreements (the “Distribution Rights”), and, as consideration therefor, MC has requested a payment of US$ * from each of FCE and POSCO Power, and each of FCE and POSCO Power have agreed to make such payment to MC upon the effective date of the POSCO Power Alliance Agreement and Technology License Agreement referred to above in the second whereas clause; and

WHEREAS, under an agreement dated April 6, 2004 MC committed to order 4 MW from FCE (“4 MW Order”), and under a separate agreement dated March 21, 2006 MC committed to order 6 MW from FCE (“6 MW Order”).


*		Confidential information has been omitted and filed separately with the Securities and Exchange Commission pursuant to a request for Confidential Treatment.

NOW THEREFORE, IT IS AGREED AS FOLLOWS:

ARTICLE I. WAIVER AND RELEASE BY MC

Subject to and conditioned upon FCE’s fulfillment of its obligations hereunder, and notwithstanding any agreement, oral or written, or understanding to the contrary herein, if any, MC hereby abandons, relinquishes, releases and waives (this “Waiver”) the Distribution Rights in Korea. This Waiver of the Distribution Rights by MC shall become effective on the Effective Date referred to in the POSCO Power Alliance Agreement, it being understood and agreed that the Distribution Rights waived hereunder shall revert back to MC if POSCO Power will not have begun manufacture of the commercial balance of plant in Korea for use with fuel cell stack modules manufactured by FCE at its facilities in Connecticut, USA, within two years of the Effective Date referred to in the POSCO Power Alliance Agreement, provided that, if the delay in the manufacture of the commercial balance of plant in Korea is caused by reasons beyond the reasonable control of POSCO Power, or any delay in FCE’s transfer of the relevant know-how, technology and other necessary information for the manufacture of the balance of plant, POSCO Power shall be given an additional reasonable period as long as POSCO Power is making good faith efforts to begin the manufacture of the commercial balance of plant, as mutually agreed upon by FCE, MC, and POSCO Power in good faith, to manufacture the commercial balance of plant in Korea. In the event of any delays for which extension of period is required, FCE, MC and POSCO Power shall start the discussion about corrective action and agree upon a reasonable extension period immediately.

ARTICLE II. FCE OBLIGATIONS

In consideration for the Waiver of the Distribution Rights, POSCO Power will agree under a separate agreement with MC to make a payment to MC in the sum of * U.S. Dollars (U.S.$ * ) within sixty (60) days after the Effective Date referred to in the POSCO Power Alliance Agreement; and FCE agrees hereunder to pay MC the sum of * U.S. Dollars (U.S.$ * ) on or before the first anniversary of the Effective Date referred to in the POSCO Power Alliance Agreement.

FCE further agrees that, as orders are received from POSCO Power under the POSCO Power Alliance Agreement, MC shall receive credit against existing backlog commitments to FCE, up to a maximum of 2.25 MW; and such credit shall be applied sequentially, first to the 4 MW Order and subsequently to the 6 MW Order, thereby reducing the order obligation from MC to FCE in aggregate by 2.25 MW. In the event that an order is placed to FCE by MC pursuant to this Agreement which exceeds the remaining backlog commitment under the 4 MW Order, FCE agrees that the remaining credit will be applied to the 6 MW Order at the same time.

FCE further acknowledges that MC is planning to establish an independent power plant (IPP) in Korea (hereinafter “IPP Project”), and that POSCO Power has consented to the IPP Project as part of the POSCO Power Alliance Agreement. In the event that the IPP Project det-ermines to use the Products at its discretion, MC agrees to purchase said Products for the IPP Project from FCE and subsequently to sell said Products to POSCO Power, subject to POSCO Power’s agreement in turn to sell said Products to the IPP Project with nominal mark-up by POSCO Power. The IPP Project shall be no larger than 5.3 MW in total output except for such IPP projects as approved by POSCO in good faith negotiation with MC. The production release from MC to FCE, under 4 MW Order first and subsequently under 6 MW Order, for such Products must be received in a form acceptable to FCE within 12 months after the Effective Date referred to in the POSCO Power Alliance Agreement, and must be delivered to the customer site within 24 months of said date, subject only to any delays caused by FCE’s normal manufacturing schedule. Pricing from FCE to MC for such Products under the IPP Project for DFC1500MA and/or DFC3000 units (“MW-class DFC Units”) shall be $ * until the remaining backlog order commitment under the 4 MW Order is exhausted; after which the pricing for MW-class DFC Units pursuant to this Agreement from FCE to MC shall be $ *.


*		Confidential information has been omitted and filed separately with the Securities and Exchange Commission pursuant to a request for Confidential Treatment.

Subject to POSCO Power’s agreement to allow the development of additional projects by MC in Korea after the second anniversary of the effective date of the POSCO Power Alliance Agreement, MC agrees to purchase power plants under such projects from POSCO Power directly.

All such IPP Projects in Korea shall require a long-term service agreement (LTSA) to be executed by the IPP with FCE, or FCE’s servicing representative as shall be designated by FCE to provide service on behalf of FCE, at prices indicated on FCE’s standard service agreements in effect as of October 2007, or other price as may be mutually agreed to make the IPP Projects economically feasible.
