As consideration for the payment described in paragraph 2 hereof, PMI hereby (i) sells, assigns and transfers to TPG, effective on the Effective Date, the QBE Note and (ii) consents to the vesting in TPG of the rights, privileges, interests and powers (but not PMI’s obligations) granted to TPG as set forth in Clause 2 of that certain Deed Poll (the “Australian Deed Poll”), dated as of May 29, 2009, by QBE in favor of the Noteholder from time to time, including but not limited to, the related rights (but not PMI’s obligations) under the SSA (such rights referred to herein collectively, as the “Granted Rights”).

2. As consideration for such sale, assignment and transfer of the QBE Note hereunder, TPG shall pay to PMI, on or before the Effective Date, the amount of US$75,000,000 in the form of cash and/or readily marketable securities.

5. PMI represents and warrants to TPG, as of the Effective Date, that:

(a) PMI (i) is a corporation duly organized, validly existing and in good standing under the laws of the State of Arizona and (ii) has all requisite power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby;

(g) no Claim (as defined in the SSA or SSD, as applicable) for breach of Warranty (as defined in the SSA or SSD, as applicable) has been asserted under the SSA, and to the best of PMI’s knowledge, there are no pending or threatened Claims for a breach of Warranty under the SSA, and PMI has no basis to believe there currently exists any such Claims that have not been asserted;

(h) as of the date hereof, the unpaid Principal balance of the QBE Note is not less than $186,505,850;
