Indemnified Party is a party thereto.&#160; Counterparty will not be liable

court of competent jurisdiction to have resulted from Citi&#8217;s breach of a term of
this Master Confirmation, willful misconduct or gross negligence.&#160; If for

such harm was not caused by Citi&#8217;s breach of any term of this Master
Confirmation, willful misconduct or gross negligence), to the amount paid or
payable by the Indemnified Party as a result of such loss, claim, damage or
liability.&#160; Counterparty also agrees that no Indemnified Party shall have
any liability to Counterparty or any person asserting claims on behalf of or in
right of Counterparty in connection with or as a result of any matter referred
to in this Master Confirmation or the Agreement except to the extent that any
losses, claims, damages, liabilities or expenses incurred by Counterparty result
from the breach of a material term of this Master Confirmation, or the
Indemnified Party&#8217;s gross negligence or willful misconduct.&#160; The provisions
of this Section 6(h) shall survive completion of the Transactions contemplated

Support Amount.&#160; In lieu of the meaning specified in Paragraph 12 of the
Form Credit Support Annex, &#8220;Credit Support Amount&#8221; means, with respect to
Counterparty as Pledgor, the sum, across all Transactions under the Master
Confirmation, of the Credit Support Amounts specified as such in the Pricing
Supplement for each such Transaction, each of which Credit Support Amounts shall
be equal, as of each day occurring during the term of any Transaction prior to
the Cash Settlement Payment Date for such Transaction, to the product of (i) the
Number of Shares for such Transaction, and (ii) the Initial Price for such
Transaction.&#160; For the avoidance of doubt, the Credit Support Amount with
respect to a Transaction will be reduced to USD 0 on the Cash Settlement Payment
Date applicable to such Transaction.&#160; Notwithstanding anything to the
contrary in Paragraphs 3(b) or 4(b) of the Form Credit Support Annex, Citi shall
Transfer to Counterparty an amount equal to the Return Amount resulting from
such reduction in the Credit Support Amount on the same day as such reduction
occurs, without any requirement for a demand therefor by Counterparty.&#160; If
the Equity Amount applicable to a Transaction is a negative number, Citi shall,
in lieu of Transferring to Counterparty the amount that would otherwise be due
to Counterparty under Paragraph 3(b) of the Form Credit Support Annex, Transfer
to Counterparty an amount net of the absolute value of the Equity Amount
applicable to such Transaction, and Counterparty&#8217;s obligation to pay the
absolute value of such Equity Amount on the relevant Cash Settlement Payment
Date shall thereby be satisfied and discharged as a result of such
netting.&#160; In addition, in connection with the payment of the Commission for
any Transaction on the Cash Settlement Payment Date for such Transaction, in
lieu of Transferring to Counterparty the amount that would otherwise be due to
Counterparty under Paragraph 3(b) of the Form Credit Support Annex, Citi shall
Transfer to Counterparty an amount net of such Commission, and Counterparty&#8217;s
obligation to pay such Commission on the relevant Cash Settlement Payment Date
shall thereby be satisfied and discharged as a result of such
netting.</font></div><br>
