If the Reorganized Company shall so postpone the filing of a registration statement, the Stockholders shall have the right to withdraw the request for registration by giving written notice to the Reorganized Company at any time and, in the event of such withdrawal, such request shall not be counted for purposes of the requests for registration to which the Stockholders are entitled pursuant to this Section 2.1. 2.2 Incidental Registration. (a) Right to Include Registrable Securities. If the Reorganized Company at any time proposes to register any of its securities under the Securities Act by registration on Form S-1, S-2 or S-3 or any successor or similar form(s) 7 (except registrations on any such Form or similar form(s) solely for registration of securities in connection with an employee benefit plan or dividend reinvestment plan or a merger or consolidation), whether or not for sale for its own account, it will each such time give prompt written notice to each of the Stockholders of its intention to do so and of the Stockholders' rights under this Section 2.2. Upon the written request of any of the Stockholders (which request shall specify the maximum number of Registrable Securities intended to be disposed of by the Stockholders), made as promptly as practicable and in any event within 30 days after the receipt of any such notice (15 days if the Reorganized Company states in such written notice or gives telephonic notice to the Stockholders, with written confirmation to follow promptly thereafter, stating that (i) such registration will be on Form S-3 and (ii) such shorter period of time is required because of a planned filing date), the Reorganized Company shall use its best efforts to effect the registration under the Securities Act of all Registrable Securities which the Reorganized Company has been so requested to register by the Stockholders; provided, however, that if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Reorganized Company shall determine for any reason not to register or to delay registration of such securities, the Reorganized Company shall give written notice of such determination and its reasons therefor to the Stockholders and (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from any obligation of the Reorganized Company to pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of the Stockholders to request that such registration be effected as a registration under Section 2.1 and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities, for the same period as the delay in registering such other securities. No registration effected under this Section 2.2 shall relieve the Reorganized Company of its obligation to effect any registration upon request under Section 2.1. The Reorganized Company will pay all Registration Expenses in connection with any registration of Registrable Securities requested pursuant to this Section 2.2. (b) Right to Withdraw.

As a condition to including any Registrable Securities in any registration statement, the Reorganized Company shall have received an undertaking reasonably satisfactory to it from each Registering Stockholder so including any Registrable Securities to 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 Reorganized Company, and each director of the Reorganized Company, each officer of the Reorganized Company and each other Person, if any, who controls the Reorganized 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 Reorganized Company through an instrument duly executed by such Registering Stockholder 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 Reorganized Company or any such director, officer or controlling Person and shall survive the transfer of such securities by such Stockholder. (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 2.6, 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 16 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 different from 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 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 other than reasonable costs of investigation (unless the first proviso in the preceding sentence shall be applicable). No indemnifying party shall be liable for any settlement of any action or proceeding effected without its written consent. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. (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 or if the allocation provided in this clause (ii) provides a greater amount to the indemnified party than clause (i) above, 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 17 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. The Registering Stockholders' obligations to contribute as provided in this subsection (d) are several and not joint and shall be in proportion to the relative value of their respective Registrable Securities covered by such registration statement. 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 Reorganized 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 Reorganized Company and the Registering Stockholders 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 any of the Stockholders. (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 Reorganized Company shall (i) facilitate the timely preparation and delivery to the Stockholders, the Other Investors 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 the Stockholders, the Other Investors 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. 2.8 Limitation on Sale of Securities. The Reorganized Company hereby agrees that if it shall previously have received a request for registration pursuant 18 to Section 2.1 or 2.2 hereof, and if such previous registration shall not have been withdrawn or abandoned, (i) the Reorganized Company shall not effect any public or private offer, sale or distribution of its securities or effect any registration of any of its equity securities under the Securities Act (other than a registration on Form S-8 or any successor or similar form which is then in effect), whether or not for sale for its own account, until a period of 90 days (or such shorter period as the Registering Stockholders shall be advised by their managing underwriter) shall have elapsed from the effective date of such previous registration, and the Reorganized Company shall so provide in any registration rights agreements hereafter entered into with respect to any of its securities; and (ii) the Reorganized Company shall use its best efforts to cause each holder of its equity securities purchased from the Reorganized Company at any time after the date of this Agreement to agree not to effect any public sale or distribution of any such securities during such period, including a sale pursuant to Rule 144 under the Securities Act. 2.9 No Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of any of the Stockholders to sell any Registrable Securities pursuant to any effective registration statement. 3. Rule 144. The Reorganized Company shall take all actions reasonably necessary to enable holders of Registrable Securities to sell such securities without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144, or (b) any similar rule or regulation hereafter adopted by the Commission including, without limiting the generality of the foregoing, filing on a timely basis all reports required to be filed by the Exchange Act. Upon the request of a Stockholder, the Reorganized Company will deliver to such holder a written statement as to whether it has complied with such requirements. 4. Amendments and Waivers. This Agreement may be amended, modified or supplemented only by written agreement of the party against whom enforcement of such amendment, modification or supplement is sought. 5. Other Investors. The parties hereto acknowledge and agree that no Other Investor has any right to request registration of the Common Stock held by such Other Investor or to participate in any registration of securities by the Reorganized Company, other than in accordance with the terms of the stockholder's agreement or option agreement, as the case may be, between such Other Investor and the Reorganized Company or any of its subsidiaries, pursuant to which such Other Investor generally may have the right or obligation to participate in any public offering in which all or a portion of the shares of Common Stock owned by the Stockholders are registered under the Securities Act. 6. Adjustments. In the event of any change in the capitalization of the Reorganized Company as a result of any stock split, stock dividend, reverse split, combination, recapitalization, merger, consolidation, or otherwise, the provisions of this 19 Agreement shall be appropriately adjusted. The Reorganized Company agrees that it shall not effect or permit to occur any combination or subdivision of shares which would adversely affect the ability of the Stockholders or the Other Investors to include any Registrable Securities in any registration contemplated by this Agreement or the marketability of such Registrable Securities in any such registration. The Reorganized Company agrees that it will take all reasonable steps necessary to effect a combination or subdivision of shares if in the reasonable judgment of the Stockholders such combination or subdivision would enhance the marketability of the Registrable Securities. 7. Notice. All notices and other communications hereunder shall be in writing and, unless otherwise provided herein, shall be deemed to have been given when received by the party to whom such notice is to be given at its address set forth below, or such other address for the party as shall be specified by notice given pursuant hereto: (a) If to any of the Stockholders, to it: c/o Appaloosa Management, L.P. 26 Main Street, 1st Floor Chatham, New Jersey 07928 Attention: James E.

No Inconsistent Agreements. The Reorganized Company will not, on or after the date of this Agreement, enter into any agreement with respect to its securities which is inconsistent with the rights granted to the Stockholders in this Agreement or otherwise conflicts with the provisions hereof.

The rights granted to the Stockholders hereunder do not in any way conflict with and are not inconsistent with any other agreements to which the Reorganized Company is a party or by which it is bound. The Reorganized Company further agrees that if any other registration rights agreement entered into after the date of this Agreement with respect to any of its securities contains terms which are more favorable to, or less restrictive on, the other party thereto than the terms and conditions contained in this Agreement are (insofar as they are applicable) with respect to the Stockholders, then the terms and conditions of this Agreement shall immediately be deemed to have been amended without further action by the Reorganized Company or the Stockholders so that the Stockholders shall be entitled to the benefit of any such more favorable or less restrictive terms or conditions. 11.
