to inquire as to the authority of the Capital Guarantee Trustee to so act or as to its compliance with any of the terms and provisions of this Capital Securities Guarantee, both of which shall be conclusively evidenced by the Capital Guarantee Trustee's or its agent's taking such action.

(x) Whenever in the administration of this Capital Securities Guarantee the Capital Guarantee Trustee shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder, the Capital Guarantee Trustee (i) may request instructions from the Holders of a Majority in liquidation amount of the Capital Securities, (ii) may refrain from enforcing such remedy or right or taking such other action until such instructions are received, and (iii) shall be protected in conclusively relying on or acting in accordance with such instructions.
