Each Holder hereby agrees, subject to the terms and conditions hereof, and provided that no Valid Withdrawal Condition shall exist, that prior to 5:00 p.m., New York City time, on the Tender Date, such Holder will accept the Exchange Offers and thereby consent to the 13% Notes Amendments and Lien Release and, if such Holder Beneficially Owns 14.25% Notes, the 14.25% Notes Amendments, in each case pursuant to the Exchange Offers and Consent Solicitations by causing the Subject Existing Notes held by such Holder to be validly tendered and deposited in accordance with the terms and conditions of the Exchange Offers and Consent Solicitations and this Agreement.

Each Holder shall only have the right to withdraw its acceptance of the Exchange Offers and revoke its tender of the Subject Existing Notes held by such Holder in the Exchange Offers and its consent to the 13% Notes Amendments and Lien Release and, if applicable, 14.25% Notes Amendments pursuant to the Consent Solicitations at the time that a Valid Withdrawal Condition exists or this Agreement is terminated pursuant to Section 7.

Subject to the terms and conditions hereof, immediately prior to the Expiration Time, each Holder who has agreed to purchase Additional Exchange Notes (as evidenced by the designation of a Specified Portion in excess of 0% on such Holder’s signature page, as such percentages may be reallocated in accordance with the definition of “Specified Portion”) hereby agrees to deposit with the Escrow Agent (as defined in Section 21) the purchase price for its Specified Portion of Additional Exchange Notes in accordance with Section 21 hereof and thereafter to purchase such Additional Exchange Notes contemporaneously with the Consummation, subject to the terms and conditions of this Agreement; provided that, in each case, (i) no Valid Withdrawal Condition exists and (ii) the Minimum Consent Condition has been satisfied. At a mutually agreed upon time prior to the Expiration Time, the Company shall notify the Holders of the principal amount of Unexchanged 14.25% Notes and the principal amount of Additional Exchange Notes to be purchased by each applicable Holder in accordance with such Holder’s Specified Portion. Immediately prior to the Consummation, each Holder who has agreed to purchase Additional Exchange Notes will direct the escrow agent to pay to the Issuer the purchase price for its Specified Portion of Additional Exchange Notes by wire transfer of immediately available funds to an account or accounts maintained by the trustee for the 14.25% Notes and held in trust in connection with the redemption and discharge of the Unexchanged 14.25% Notes provided that (i) no Valid Withdrawal Condition exists and (ii) the Minimum Consent Condition has been satisfied. Without limitation of the Company’s rights to enforce this Agreement against any defaulting Holder or to seek an alternate purchaser for the Additional Exchange Notes to have been purchased by a defaulting Holder, in the event one or more Holders fails to deposit its Specified Portion of Additional Exchange Notes in accordance with this Section 2(c), the non-defaulting Holders may but shall not be obligated to purchase the aggregate principal amount of all such Additional Exchange Notes prior to the close of business as of the date of the Consummation.

Subject to the terms and conditions hereof, immediately prior to the Consummation, (i) IHC shall call all Unexchanged 14.25% Notes for redemption in accordance with the terms of the indenture governing the 14.25% Notes and (ii) in connection therewith, Company shall (A) cause all conditions to such redemption to be satisfied and (B) deposit with the trustee for the 14.25% Notes such amounts as may be necessary to discharge, effective as of such date of Consummation, IHC’s obligations under the indenture governing the 14.25% Notes (and Company’s obligations to redeem Unexchanged 14.25% Notes in accordance with the provisions hereof). Each of the Holders who purchases Additional Exchange Notes agrees that its purchase of Additional Exchange Notes pursuant to Section 2(c) shall be funded in a manner so as to enable the proceeds of such purchase to be included in the deposit referenced in the immediately preceding sentence. The Company agrees to deposit with the Escrow Agent its portion of the redemption price for the Unexchanged 14.25% Notes immediately prior to the Expiration Time in accordance with Section 21 hereof.

Notwithstanding anything in this Agreement to the contrary (but without limiting the provisions of the definition of “Valid Withdrawal Condition” set forth herein or any other provisions hereof that require that all 14.25% Notes be exchanged and/or redeemed concurrently with the Consummation), the Company may elect not to solicit consents to the 14.25% Notes Amendments, and in the event the

Company elects not to solicit such consents, (i) this Agreement will be deemed to have been amended mutatis mutandis as if references to the 14.25% Notes Amendments had never been included herein, and (ii) such election will not be deemed to be a Prohibited Modification or a breach of this Agreement.

Each Holder represents and warrants to the Company as follows:
