7. In exercising the rights, duties and obligations prescribed or confirmed by this Agreement, the Trustee will act honestly and in good faith and will exercise that degree of care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

8. The Undersigned and the Issuer agree from time to time and at all times hereafter well and truly to save, defend and keep harmless and fully indemnify the Trustee, its successors and assigns from and against all loss, costs, charges, suits, demands, claims, damages and expenses which the Trustee, its successors or assigns may at any time or times hereafter bear, sustain, suffer or be put unto for or by reason or on account of its acting pursuant to this Agreement or anything in any manner relating thereto or by reason of the Trustee’s compliance in good faith with the terms hereof.

12. Except as herein otherwise provided, the Trustee is authorized and directed to disregard any and all notices and warnings which may be given to it by any of the parties hereto or by any other person, firm, association or corporation. It will, however, obey the order, judgment or decree of any court of competent jurisdiction, and it is hereby authorized to comply with and obey such orders, judgments or decrees and in case of such compliance, it shall not be liable by reason thereof to any of the parties hereto or to any other person, firm, association or corporation, even if thereafter any such order, judgment or decree may be reversed, modified, annulled, set aside or vacated.

13. If the Trustee receives any valid court order contrary to the instructions contained in this Agreement, the Trustee may continue to hold the Pooling Shares until the lawful determination of the issue between the parties hereto.

14. If written notice of protest is made by any of the Undersigned and/or the Issuer to the Trustee to any action contemplated by the Trustee under this Agreement, and such notice sets out reasons for such protest, the Trustee may, at its sole discretion, continue to hold the Pooling Shares until the right to the documents is legally determined by a court of competent jurisdiction or otherwise.
