| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | the Dividend would be required to be paid other than out of the profits of AofA, within the meaning of section 254T of the Corporations Act; or
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the declaration or payment of the Dividend would cause AofA to be unable to pay all its debts as and when they become due and payable, taking into account the requirements of this

| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | payment of the Dividend would result in AofA having insufficient franking credits available to fully frank the next scheduled Dividend relating to a Minimum Dividend Amount, taking
into account franking credits that would reasonably be expected to be generated or received by AofA by the end of the franking year (as defined in the 1997 Act) in which that next scheduled Dividend would be paid;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

820-90 or section 820-190 of the 1997 Act (whichever is applicable to AofA for the tax year in which the Dividend would be paid).
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | If, but for this clause 3.2(b), clause 3.2(a)(iii) would apply to preclude the payment of any Excess Dividend (whether wholly or in part), the parties will promptly negotiate in
good faith and use reasonable endeavours to procure that clause 3.2(a)(iii) does not so apply, or applies only to the minimum extent possible, including in the case of clause 3.2(a)(iii)(d) by:

year in which indebtedness is being determined). However, if, but for this sentence, this clause 4.8(b) would apply to preclude the making of Enterprise Loans (or the making of Enterprise Loans to a certain extent), the parties will promptly
negotiate in good faith and use reasonable endeavours to procure that this clause 4.8(b) does not so apply, or applies only to restrict the making of Enterprise Loans to the minimum extent possible, including:
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

purposes of determining the level of AofAs maximum allowable debt amount for the purposes of section 820-90 or section 820-190 (as applicable) of the 1997 Act, in which case, AofA, AAH and Alcoa may not unreasonably refuse or delay
their assistance in such effort and will provide such information in their possession or control as may be reasonably requested for the valuation,

|--- | --------------

If either Alcoa or Alumina fails to
pay (or procure payment by its Affiliates of) its Share of the funds requested in a Valid Call when due as required by this clause 4 (including by failing to make payment of a Contribution Amount to the Enterprise Funding Partnership), the parties
agree that the consequences of such failure will be the same as those that apply to a failure to make an equity contribution required by the Charter, as set out in section 8 of the Charter (as such section 8 may be modified as provided in

|Repayment:                  |  | (a)      Each drawing will be repayable over the remaining Repayment Term. Subject to paragraph (b), a
pro rata payment in respect of each such drawing (each a Scheduled Payment) will be due on 31 January of each year and on the Final Repayment Date (each a Repayment Date).                                                       
|                            | 
|                            |  | (b)      If on any Repayment Date (other than the Final Repayment Date) the total amount of Scheduled Payments
for that Repayment Date exceeds 100% of the Borrowers available cash on that Repayment Date, the Borrower will only be required to pay the Scheduled Payments to the extent of its available cash on that Repayment Date.
