Market Terms Schedule

Australia

Lender acknowledges and accepts that:

with regards to any Institutional Share Offering (“ISO”) offered by an Australian issuer to Lender, Lender shall be solely responsible for informing J.P. Morgan that Lender has (a) been invited to participate in such ISO and (b) intends to, or otherwise, exercise any rights in relation to Securities on Loan;

due to the nature of an ISO, J.P. Morgan will be unaware of such ISO arising and will therefore rely solely on Lender’s notification provided in (a) above;

subject to Clause 4 hereof (Instructions), Lender must provide election Instructions to J.P. Morgan:

prior to market expiry where the timing of the ISO announcement makes it reasonably practicable to permit election Instructions to be given prior to such market expiry; and

ii.

in all other cases, prior to the applicable Cut-Off Time.

Such election Instructions must specify whether Lender wishes to (i) take up the ISO; (ii) lapse the ISO; or (iii) lapse and take up any available cashbook build. Upon receipt, J.P. Morgan shall use reasonable endeavours to forward such election Instructions to Borrower;

J.P. Morgan shall not be liable to Lender in the event that:

iii.

Lender does not provide to J.P. Morgan any election Instructions; or

iv.

Lender fails to provide J.P. Morgan with timely election Instructions with respect to such an ISO, and J.P. Morgan in its sole discretion does not take any action in relation to such election Instructions; or

election Instructions were received by Borrower after market expiry of the ISO and Borrower is unable to accept such election Instructions.

II.

France

Lender acknowledges and accepts that when lending Securities issued by French issuers (“French Securities”), any additional tax credits (including, but not limited to, Credit d’Impot) that may be due to the holder of such French Securities had they not been on Loan over record date, will not form part of the manufactured Income (as defined in the applicable MSLA) that is collected from a Borrower on behalf of the Lender.

III.

Hungary, Japan, Mexico, Singapore

To the extent that Lender has approved in this Schedule that the following jurisdictions are eligible markets, Lender represents and warrants that it does not have a “permanent establishment” in:

Hungary
