              The
                Pledgor shall be responsible for all the fees (including but not
                limited
                to any taxes, formalities fees, management fees, litigation fees,
                attorney's fees, and various insurance premiums in connection with
                disposition of Pledge) incurred by the Pledgor for the reason that
                (1) the
                Pledgor fails to pay any payable taxes, fees or charges in accordance
                with
                this Agreement; or (2) the Pledgee has recourse to any foregoing
                taxes,
                charges or fees by any means for other
                reasons.

              12.1

            	
              If
                this Agreement is delayed in or prevented from performing in the
                event of
                Force Majeure (“Event of Force Majeure”), only within the limitation of
                such delay or prevention, the affected party is absolved from any
                liability under this Agreement. Force Majeure, which includes acts
                of
                governments, acts of nature, fire, explosion, typhoon, flood, earthquake,
                tide, lightning, war, means any unforeseen events beyond the prevented
                party’s reasonable control and cannot be prevented with reasonable care.
                However, any shortage of credit, capital or finance shall not be
                regarded
                as an event beyond
                a Party’s reasonable control. The Pledge effected by Force Majeure who
                claims for exemption from performing any obligations under this Agreement
                or under any Article herein shall notify the other party of such
                exemption
                promptly and advice him of the steps to be taken for completion of
                the
                performance.

              12.2

            	
              The
                party affected by Force Majeure shall not assume any liability under
                this
                Agreement. However, subject to the party affected by Force Majeure
                having
                taken its reasonable and practicable efforts to perform this Agreement,
                the Party claiming for exemption of the liabilities may only be exempted
                from performing such liability as within limitation of the part
                performance delayed or prevented by Force Majeure. Once causes for
                such
                exemption of liabilities are rectified and remedied, both parties
                agree to
                resume performance of this Agreement with their best
                efforts.
