APPOINTMENT OF THE COLLATERAL AGENT AND RELATED MATTERS 2.1 APPOINTMENT AND DUTIES OF THE COLLATERAL AGENT; COLLATERAL AGENT AS JOINT CREDITOR (a) The Requisite Noteholders acting pursuant to the Second Noteholders Meeting have approved the Appointment of the Collateral Agent and, as a result thereof and pursuant hereto, KBC 2 Execution copy Bank NV is hereby irrevocably appointed to act as collateral agent hereunder and under the Subsidiary Guaranties and the Collateral Documents on behalf of and for the benefit of the Noteholders with such powers as are expressly granted to the Collateral Agent by the terms of this Agreement, the Subsidiary Guaranties and the Collateral Documents, together with such other powers as are reasonably incidental thereto. The Collateral Agent hereby accepts such appointment, and agrees to act as Collateral Agent as set out herein and therein. The Credit Parties, by execution of a counterpart hereof, and the Collateral Agent acknowledge that the Collateral Agent, as joint creditor of the Obligations, acts in respect of the Collateral, the Subsidiary Guaranties and the Collateral Documents, in its own name and for its own account, and for the benefit of the Noteholders, as set out herein. (b) In furtherance but not in limitation of the foregoing, the Collateral Agent is authorised to: (i) perform the duties and to exercise the rights, powers and discretions of a secured creditor under the applicable law in respect of the Subsidiary Guaranties, the Collateral Documents and the Collateral, together with any other incidental rights, powers and discretions; (ii) execute each Subsidiary Guaranty and Collateral Document expressed to be executed by the Collateral Agent; and (iii) take the steps required to perfect the Collateral. (c) The Issuer and each Subsidiary Guarantor agree that the Collateral Agent shall be the joint creditor (together with the relevant Noteholders) of each and every obligation of the Issuer and of each Subsidiary Guarantor towards the Noteholders under the Notes and under each Subsidiary Guaranty, and the other Credit Documents to which the Issuer or such Subsidiary Guarantor is party, as the case may be. Accordingly, the Collateral Agent will have its own independent right to demand performance by the Issuer and each Subsidiary Guarantor of those obligations. However, any discharge of such obligations to one of the Collateral Agent or a Noteholder shall, to the same extent, discharge the corresponding obligation owing to the other. Without limiting or affecting the Collateral Agent's rights against the Issuer or any Subsidiary Guarantor (whether under this paragraph or under any provision of any Collateral Document), the Collateral Agent agrees for the benefit of each Noteholder (on a several and divided basis) that, subject as set out in the next sentence, it will not exercise its rights as a joint creditor with a Noteholder except as provided in this Collateral Agency Agreement. However, for the avoidance of doubt, nothing in the previous sentence shall in any way limit the Collateral Agent's right to act in the protection or preservation of rights under or to enforce any Subsidiary Guaranty or Collateral Document or other Credit Document (or to do any act reasonably incidental to any of the foregoing). 2.2 POSITION OF THE COLLATERAL AGENT (a) To the extent that it is a Noteholder, the Collateral Agent shall have the same rights and powers as any other Noteholder and may exercise such rights and powers as though it were not the Collateral Agent. (b) The Collateral Agent may: (i) carry on any business with a Noteholder, the Issuer, a Subsidiary Guarantor, or any of their respective Affiliates; and 3 Execution copy (ii) retain any profits or remuneration it receives in relation to any other business it carries on with a Noteholder, the Issuer, a Subsidiary Guarantor, or any of their respective Affiliates. 2.3 RELIANCE The Collateral Agent may: (a) rely on any notice or document believed by it in good faith to be genuine and correct and to have been signed by, or with the authority of, the proper Person or Persons; (b) rely on any statement made by any Person regarding any matters which may reasonably be assumed to be within his knowledge or within his power to verify; (c) rely on the written direction of the Requisite Noteholders or certifying that the Persons signing such direction constitute the Requisite Noteholders; (d) engage, pay for and rely on professional advisers selected by it; and (e) act under the Subsidiary Guaranties and the Collateral Documents through its personnel and agents. 2.4 REQUISITE NOTEHOLDERS' INSTRUCTIONS (a) The Collateral Agent shall be entitled to act and shall be fully protected if it acts upon the instructions of the Requisite Noteholders in the exercise of any right, power or discretion or any matter not expressly provided for in the Subsidiary Guaranties or the Collateral Documents. Any such instructions given by the Requisite Noteholders will be binding on all the Noteholders. In the absence of instructions from the Requisite Noteholders, the Collateral Agent may act as it considers to be in the best interests of all the Noteholders. (b) The Collateral Agent may assume that, unless it has received notice to the contrary, any right, power, authority or discretion vested in any Noteholder has not been exercised. (c) The Collateral Agent may require the receipt of security reasonably satisfactory to it, whether by way of payment in advance or otherwise, against any liability or loss which it may incur in complying with the instructions of the Requisite Noteholders. (d) Persons indirectly holding Notes through accounts held with intermediary institutions shall be entitled to instruct the Collateral Agent, shall be deemed to be a "Noteholder" for purposes of such instructions and the Collateral Agent shall be entitled to rely thereon. 2.5 APPOINTMENT OF CO-COLLATERAL AGENT The Collateral Agent may and, upon the request of the Requisite Noteholders, shall, upon the consent of the Issuer (which consent shall not be unreasonably withheld and shall not be required if an Event of Default has occurred and is continuing) and by an instrument in writing delivered to the Issuer, the Subsidiary Guarantors and each Noteholder, appoint a bank or trust company or an individual to act as separate Collateral Agent or co-Collateral Agent in a jurisdiction where the Collateral Agent is disqualified from acting or for any other purpose deemed by the Collateral Agent or the Requisite Noteholders to be advantageous to their respective interests, such separate Collateral Agent or co-Collateral Agent to exercise only such rights and to have only such duties as shall be specified in the instrument of appointment. The Issuer will pay the reasonable compensation and expenses of any such 4 Execution copy separate Collateral Agent or co-Collateral Agent and, if requested by the Collateral Agent, such separate Collateral Agent or co-Collateral Agent or the Requisite Noteholders, the Issuer and the Subsidiary Guarantors will enter into an amendment to this Agreement, satisfactory in substance and form to the Collateral Agent or the Requisite Noteholders and such separate Collateral Agent or co-Collateral Agent, confirming the rights and duties of such separate Collateral Agent or co-Collateral Agent. 3.
