      SECTION 6.6     Observer.

Notwithstanding anything to the contrary contained in this Agreement, the Company may in its discretion withdraw any registration commenced pursuant to this Section 2.2 without liability to the holders of Registrable Securities.

      (b) Indemnification by Mitsui. As a condition to including any Registrable Securities in any registration statement, Mitsui shall indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a) of this Section 2.6) the Company, and each director of the Company, each officer of the Company and each other Person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, but only to the extent such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of Mitsui specifically stating that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement; provided, however, that the liability of such indemnifying party under this Section 2.6(b) shall be limited to the amount of proceeds (net of expenses and underwriting discounts and commissions) received by such indemnifying party in the offering giving rise to such liability. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the transfer of such securities by Mitsui.

      (c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding subsections of this Section 2.6, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action or proceeding; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding subsections of this Section 2.4, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice, and shall not relieve the indemnifying party from any liability which it may have to the indemnified party otherwise than under this Section 2.6. In case any such action or proceeding is brought against an indemnified party, the indemnifying party shall be entitled to participate therein and, unless in the opinion of outside counsel to the indemnified party a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party; provided, however, that if the defendants in any such action or proceeding include both the indemnified party and the indemnifying party and if in the opinion of outside counsel to the indemnified party there may be legal defenses available to such indemnified party and/or other indemnified parties which are in conflict with or in addition to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to defend such action or proceeding on behalf of such indemnified party or parties, provided, however, that the indemnifying party shall be obligated to pay for only one counsel and one local counsel for all indemnified parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal expenses subsequently incurred by the latter in connection with the defense thereof (unless the first proviso in the preceding sentence shall be applicable). No indemnifying party shall be liable for any settlement

B-9

      (d) Contribution. If the indemnification provided for in this Section 2.6 shall for any reason be held by a court to be unavailable to an indemnified party under subsection (a) or (b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, then, in lieu of the amount paid or payable under subsection (a) or (b) hereof, the indemnified party and the indemnifying party under subsection (a) or (b) hereof shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating the same), (i) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand, and the indemnified party on the other, which resulted in such loss, claim, damage or liability, or action in respect thereof, with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as shall be appropriate to reflect not only the relative fault but also the relative benefits received by the indemnifying party and the indemnified party from the offering of the securities covered by such registration statement as well as any other relevant equitable considerations. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 2.6(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the preceding sentence of this Section 2.6(d). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. In addition, no Person shall be obligated to contribute hereunder any amounts in payment for any settlement of any action or claim effected without such Person’s consent, which consent shall not be unreasonably withheld. Notwithstanding anything in this subsection (d) to the contrary, no indemnifying party (other than the Company) shall be required to contribute any amount in excess of the proceeds (net of expenses and underwriting discounts and commissions) received by such party from the sale of the Registrable Securities in the offering to which the losses, claims, damages or liabilities of the indemnified parties relate.

      (e) Other Indemnification. Indemnification and contribution similar to that specified in the preceding subsections of this Section 2.6 (with appropriate modifications) shall be given by the Company and Mitsui with respect to any required registration or other qualification of securities under any federal, state or blue sky law or regulation of any governmental authority other than the Securities Act. The indemnification agreements contained in this Section 2.6 shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the transfer of any of the Registrable Securities by Mitsui.

      (f) Indemnification Payments. The indemnification and contribution required by this Section 2.6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred.

      2.7     Unlegended Certificates. In connection with the offering of any Registrable Securities registered pursuant to this Section 2, the Company shall promptly after the sale of such Registrable Securities (i) facilitate the timely preparation and delivery to Mitsui and the underwriters, if any, participating in such offering, of unlegended certificates representing ownership of such Registrable Securities being sold in such denominations and registered in such names as requested by Mitsui or such underwriters, and (ii) instruct any transfer agent and registrar of such Registrable Securities to release any stop transfer orders with respect to any such Registrable Securities.
