(viii)         each Underwriter severally represents, warrants and agrees that: in relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), it has not made and will not make an offer of the Securities to the public in that Relevant Member State, except that it may make an offer of Securities to the public in that Relevant Member State at any time under the following exemptions under the Prospectus Directive (as defined below), if they have been implemented in that Relevant Member State: (i) to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities; (ii) to any legal entity which has two or more of the following: (1) an average of at least 250 employees during the last financial year, (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; (iii) to fewer than 100 natural or legal persons (other than qualified investors as defined in the Prospectus Directive) subject to obtaining the prior consent of the Representatives for any such offer; or (iv) in any other circumstances falling within Article 3(2) of the Prospectus Directive, provided that no such offer of Securities to the

12

public shall result in a requirement for the publication by the Bank or the Underwriters of a prospectus pursuant to Article 3 of the Prospectus Directive.  For the purposes of this preceding paragraph, the expression “offer of Securities to the public” in relation to any Securities in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase the Securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

SECTION 2.            Purchase and Sale; Closing .

(a)            Purchase of the Securities by the Underwriters .  On the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, the Bank agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter agrees, severally and not jointly, to purchase from the Bank the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 99.548% of the principal amount.  The Bank will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.  The Bank understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Prospectus.  The Bank acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter, provided that any such affiliate agrees to be bound by the representations, warranties and agreements of the Underwriters set forth in this Agreement, and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

(b)            Payment .  Payment for and delivery of the Securities will be made at the offices of Sidley Austin LLP , 787 Seventh Avenue, New York, New York 10019 at 10:00 a.m. New York City time on August 27, 2009, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Bank may agree upon in writing.  The time and date of such payment and delivery is referred to herein as the “Closing Date”.  Payment for the Securities shall be made by wire transfer in immediately available funds to the account(s) specified by the Bank to the Representatives against delivery to the nominee of The Depository Trust Company (“DTC”), for the account of the Underwriters, of one or more global notes representing the Securities (collectively, the “Global Note”), with any transfer taxes payable in connection with the sale of the Securities duly paid by the Bank.  The Global Note will be made available for inspection by the Representatives not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date.

(c)            No Fiduciary Duty .  The Bank acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Bank with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Bank or any other person.  Additionally, under this Agreement, neither the Representatives nor any other

13

Underwriter is advising the Bank or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction.  The Bank will consult with its own advisors concerning such matters and will be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and, except as expressly provided in this Agreement,  the Underwriters will have no responsibility or liability to the Bank with respect thereto. Any review by the Underwriters of the Bank, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and will not be on behalf of the Bank.

(b)            Amendments or Supplements; Issuer Free Writing  Prospectuses .  Before using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus relating to the Securities, and before filing any amendment or supplement to the Registration Statement or the Prospectus, in each case prior to the expiry of the Prospectus Delivery Period (as defined below), whether before or after the time that the Registration Statement becomes effective, the Bank will furnish to the Representatives and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not use or refer to, or authorize or approve others to use or refer to, in each case in connection with the offering of the Securities, or file with the Commission, any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement to which the Representatives reasonably object and shall have given notice of such objection to the Bank in a timely manner.

(c)            Notice to the Representatives .  The Bank will advise the Representatives promptly, and confirm such advice in writing, (i) when the Registration Statement has become effective, if it is not effective prior to the date of this Agreement; (ii) when any amendment to the Registration Statement has been filed or becomes effective; (iii) when any supplement to the Prospectus or any amendment to the Prospectus or any Issuer Free Writing Prospectus has been filed; (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (v) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (vi) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus or the Time of Sale Information as then amended or supplemented would include any untrue statement of a material

14

fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus or the Time of Sale Information is delivered to a purchaser, not misleading; and (vii) of the receipt by the Bank of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Bank will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(d)            Time of Sale Information .  If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances, not misleading or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Bank will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(e)            Delivery of Copies .  The Bank will deliver, without charge, (i) to the Representatives, one signed copy of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith and documents incorporated by reference therein; and (ii) to each Underwriter (A) a conformed copy of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith (other than any exhibits or consents incorporated by reference therein) and (B) during the Prospectus Delivery Period, as many copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) and each Issuer Free Writing Prospectus as the Representatives may reasonably request.  As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Securities as in the opinion of counsel for the Underwriters a prospectus relating to the Securities is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Securities by any Underwriter or dealer.

(f)             Continued Compliance with Securities Laws .  If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Bank will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the

15

Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law.

(g)            Blue Sky Qualifications .  The Bank will endeavor, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Underwriters may request and to which the Bank shall not have objected, and will maintain such qualifications in effect for as long as may be required for the distribution of the Securities and will pay any fee of the Financial Industry Regulatory Authority Inc. (“FINRA”) in connection with the review of the offering of the Securities; provided, however, that in connection therewith the Bank shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to take any action that would subject itself to taxation in respect of doing business in such jurisdiction or to service of process in suits, other than those arising out of the offering or issuance of the Securities, in any jurisdiction in which it is not otherwise so subject.  The Bank will file promptly such statements and reports as may be required by the laws of each jurisdiction in which the Securities have been qualified as above provided.  The Bank will promptly advise the Representatives of the receipt by the Bank of any notification with respect to the suspension of the qualification of the Securities for sale in any such state or jurisdiction or the initiating or threatening of any proceeding for such purpose.

(h)            Earnings Statement .  The Bank will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder.

(i)             Clear Market .  During the period from the date hereof through the Closing Date, the Bank will not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of, any United States dollar-denominated debt securities issued or guaranteed by the Bank for its own account and having a tenor of more than one year; provided, however , that nothing in this Agreement shall prevent the Bank from offering, selling, contracting to sell or otherwise disposing of (i) United States dollar-denominated debt securities, whether or not guaranteed by the Commonwealth of Australia, under the Bank’s European Medium-Term Notes program outside of the United States or (ii) United States dollar-denominated debt securities guaranteed by the Commonwealth of Australia under the Bank’s United States Medium-Term Notes program either inside or outside the United States.

SECTION 6.            Indemnification .

(a)            Indemnification of Underwriters .  The Bank agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 405 under the 1933 Act, its and their partners, directors and officers and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

(i)                 against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, as amended or supplemented, any Issuer Free Writing Prospectus (when taken together with the Time of Sale Information) or any Time of Sale Information (collectively, the “Indemnified Disclosure”), or the omission or alleged omission therefrom of a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)                against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the prior written consent of the Bank; and

(iii)               against any and all reasonable expense whatsoever, (including, subject to Section 6(c) hereof, the reasonable fees and disbursements of counsel chosen in accordance with Section 6(c) below), incurred, in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however , that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Bank by any Underwriter through the Representatives expressly for use in the Indemnified Disclosure.

(b)            Indemnification of the Bank, Directors and Officers .  Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Bank, its directors, its officers who signed the Registration Statement, and each person, if any, who controls the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and

20

all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a) above, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information in reliance upon and in conformity with written information furnished to the Bank by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information.

(c)            General .  In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) above, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon the request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding.  Any failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have otherwise than on account of this indemnity agreement. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and, in the reasonable opinion of counsel to the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred.  Such firm shall be designated in writing by the Underwriters in the case of parties indemnified pursuant to paragraph (a) above and by the Bank in the case of parties indemnified pursuant to paragraph (b) above.  The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d)            Settlement without Consent if Failure to Reimburse .  If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) above effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received

21

notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7.            Contribution .  In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Bank and the Underwriter in respect of which such indemnity agreement is held to be unenforceable shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Bank and such Underwriter, as incurred, in such proportions that such Underwriter is responsible for that portion represented by the total commissions and underwriting discounts received by such Underwriter as set forth in the table on the cover page of the Prospectus bears to the total net proceeds (before deducting expenses) received by the Bank from the sale of the Securities, and the Bank is responsible for the balance; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, each director of the Bank, each officer of the Bank who signed the Registration Statement, and each person, if any, who controls the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Bank.  The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of securities sold to or through each Underwriter and not joint.

SECTION 8.            Representations, Warranties and Agreements to Survive Delivery .  All representations, warranties and agreements contained in this Agreement or contained in certificates of officers of the Bank submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of an Underwriter or controlling person of an Underwriter, or by or on behalf of the Bank, and shall survive each delivery of and payment for any of the Securities.

SECTION 9.            Termination .

(a)            Termination .  This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Bank, if after execution and delivery of this Agreement and prior to the Closing Date (i) there has been, since the date of this Agreement or since the respective dates as of which information is given in the Registration Statement, the Time of Sale Information or the Prospectus, any material adverse change, or any development that could reasonably be expected to result in a prospective material adverse change, in the condition, financial or otherwise, or in or affecting the earnings or operations of the Bank and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, which, in the reasonable judgment of the Representatives, makes it impracticable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus; (ii) there shall have occurred any

suspension or limitation of trading in securities generally on the New York Stock Exchange, Inc., or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Bank on any exchange or in the over-the-counter market; (iii) there shall have occurred any banking moratorium declared by United States federal, New York or Australian authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States ; (iv) after the time and date of this Agreement, there has been any actual or prospective change in Australia or United States tax laws or regulations that materially adversely affects the Securities to be issued pursuant to this Agreement; (v) there shall have occurred any outbreak or escalation of major hostilities in which the United States or Australia is involved, any declaration of war by Congress or any other national or international calamity or emergency and, in the reasonable judgment of the Representatives, the effect of any such outbreak, escalation, declaration, calamity or emergency makes it impractical to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

(b)            Liabilities .  If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 13, 14, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 10.          Default by One or More of the Underwriters .  (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Bank on the terms contained in this Agreement.  If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Bank shall be entitled to a further period of 36 hours within which to procure other persons reasonably satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms.  If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Bank may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Bank or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Bank agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes.  As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b)            If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Bank as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Bank shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter

23

agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)            If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Bank as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Bank shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters.  Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Bank, except that the Bank will continue to be liable for the payment of expenses as set forth in Section 4 hereof and except that the provisions of Sections 6 and 7 hereof shall not terminate and shall remain in effect.

(d)            Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Bank or any non-defaulting Underwriter for damages caused by its default.

SECTION 11.          Notices .  All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.  Notices to the Underwriters shall be directed to the Representatives c/o Banc of America Securities LLC, One Bryant Park, NY1-100-18-03, New York, New York 10036, Attention: High Grade Transaction Management/Legal.  Notices to the Bank shall be directed to Westpac Banking Corporation, Level 19, 275 Kent Street, Sydney NSW 2000, Australia, attention of Global Funding, Group Treasury.  Any party to this Agreement may from time to time designate another address to receive notice pursuant to this Agreement by notice duly given in accordance with the terms of this Section 11.

(b)           The Bank hereby irrevocably designates, appoints and empowers its Senior Vice President & Chief Operating  Officer, with offices at 575 Fifth Avenue, New York, New York 10017, as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and its properties, assets and revenues, service of any and all legal process, summons, notices and documents which may be served in any such action, suit or proceeding brought in any United States or State court with respect to its obligations, liabilities or any other matter arising out of or in connection with this Agreement and which may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts.  If for any reason such designee, appointee and agent hereunder shall cease to be available to act as such, the Bank agrees to designate a new designee, appointee and agent in The City of New York on the terms and for the purposes of this Section 13 satisfactory to the Underwriters.  The Bank further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by serving a copy thereof upon the relevant agent for service of process referred to in this Section 13 (whether or not the appointment of such agent shall for any reason prove to be ineffective or such agent shall accept or acknowledge such service) or by mailing copies thereof by registered or certified mail, first class, postage prepaid, to the Bank at its address specified in or designated pursuant to this Agreement.  The Bank agrees that the failure of any such designee, appointee and agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon.  Nothing herein shall in any way be deemed to limit the ability of the holders of the Securities, the Underwriters and the other persons referred to in Section 12 hereof to serve any such legal process, summons, notices and documents in any other manner permitted by applicable law or to obtain jurisdiction over the Bank or bring actions, suits or proceedings against the Bank in any jurisdiction, and in any manner, as may be permitted by applicable law.  The Bank hereby irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with this Agreement brought in the United States federal courts located in The City of New York or the courts of the State of New York and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

(c)           The provisions of this Section 13 shall survive any termination of this Agreement, in whole or in part.

SECTION 14.         Foreign Taxes .  Any amounts payable hereunder, other than payments of interest, principal or premium, if any, in respect of any of the Securities, to an Underwriter shall be made free and clear of and without withholding or deduction for or on account of any and all taxes, levies, imposts, duties, charges or fees of whatsoever nature now or hereafter imposed, levied, collected, deducted or withheld or assessed by or on behalf of Australia or any political

25

subdivision thereof or by any jurisdiction, other than the United States of America or any taxing authority or political subdivision thereof, in which the Bank has a branch, an office or any agency from which payment is made (a “Taxing Authority”), excluding (i) any such tax which would not have been imposed if such Underwriter had no present or former connection with any such jurisdiction other than the performance of its obligations hereunder, (ii) any income or franchise tax imposed on the net income of such Underwriter by any jurisdiction of which such Underwriter is a resident, citizen or domiciliary, or in which such Underwriter is engaged in business and (iii) any tax imposed that would not have been imposed but for the failure by such Underwriter to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with any Taxing Authority if compliance is required by such Taxing Authority as a pre-condition to exemption from, or reduction in rate of, such tax (all such non-excluded taxes, the “Foreign Taxes”).  If, by operation of law or otherwise, that portion of amounts payable hereunder represented by Foreign Taxes withheld or deducted cannot be paid or remitted, then amounts payable under this Agreement shall be increased to such amounts as are necessary to yield and remit to such Underwriter amounts which, after deduction of all Foreign Taxes (including all Foreign Taxes payable on such increased payments) equal the amounts that would have been payable if no Foreign Taxes had been so withheld or deducted (the “Additional Amount”); provided , however , that no Additional Amount with respect to any payment or compensation to such Underwriter hereunder shall be required to be paid in the event that such payment or compensation is subject to such Foreign Tax by reason of such Underwriter being connected with the jurisdiction of the Taxing Authority other than by reason of merely receiving payment hereunder.

SECTION 15.         Waiver of Sovereign Immunity .  To the extent that the Bank or any of its properties, assets or revenues may have or may hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty, from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Agreement or the Securities, the Bank hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement.

SECTION 16.         Judgment Currency .  The Bank agrees to indemnify each Underwriter against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “Judgment Currency”) other than United States dollars and as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the rate of exchange at which such Underwriter would have been able to purchase United States dollars with the amount of the Judgment Currency actually received by such Underwriter had such Underwriter utilized such amount of Judgment Currency to purchase United States dollars as promptly as practicable upon such Underwriter’s receipt thereof.  The foregoing indemnity shall constitute a separate and independent obligation of the Bank and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid.  The term “rate of exchange”

26

shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.
