 market practice for use of the Benchmark Replacement exists, in such other manner as we (in consultation, to the extent practicable, with the calculation agent) or our designee (in consultation with us) determines is appropriate (acting in good faith)).

Any determination, decision or election that may be made by us pursuant to the Benchmark Transition Provisions will, if made by us, be made in consultation with the calculation agent, to the extent practicable, and, if made by our designee, be made after consulting with us and, in each case, will become effective without consent from the holders of the Floating Rate Notes or any other party. Any designee that we may appoint in connection with these determinations may be our affiliate. When performing such functions, potential conflicts of interest may exist between us, our designee or the calculation agent and holders of the Floating Rate Notes. All determinations by us (in consultation with the calculation agent, to the extent practicable) or our designee (after consulting with us) will be conclusive for all purposes and binding on us and holders of the Floating Rate Notes absent manifest error. In making these potentially subjective determinations, we, our designee or the calculation agent may have economic interests that are adverse to your interests, and such determinations may adversely affect the value of and return on the Floating Rate Notes. Because the Benchmark Replacement is uncertain, we (in consultation, to the extent practicable, with the calculation agent) or our designee (in consultation with us) are likely to exercise more discretion in respect of calculating interest payable on the Floating Rate Notes than would be the case in the absence of a Benchmark Transition Event and related Benchmark Replacement Date. Neither they nor we will have any obligation to consider your interests as a noteholder in taking any action that might affect the value of the Floating Rate Notes.

The application of a Benchmark Replacement and Benchmark Replacement Adjustment, and any implementation of Benchmark Replacement Conforming Changes, could result in adverse consequences to the amount of interest payable on the Floating Rate Notes, which could adversely affect the return on, value of and market for such Floating Rate Notes. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark that it is replacing.
