11

(b)                                 the Guarantor’s failure to make due payment under the Guarantee; or

(c)                                  Notes not being issued for any reason (other than as a result of the failure of any Dealer to pay) after an agreement for the sale of such Notes has been made; or

(d)                                 any breach or alleged breach of the representations, warranties, covenants or agreements made by the relevant Issuer or the Guarantor in this Agreement, or

(e)                                  any untrue statement or alleged untrue statement of any material fact contained in the Disclosure Documents or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading in any material respect unless, in the case of an alleged untrue statement or omission, the allegation is being made by any of the Dealer’s Related Parties,

the Issuers or, as the case may be, the Guarantor shall pay to the Dealer on demand an amount equal to such Loss.  The Dealer shall not have any duty or other obligation, whether as fiduciary or trustee for any of its Related Parties or otherwise, to recover any such payment or to account to any other person for any amounts paid to it under this Clause.

(f)                                   In case any allegation as described in sub-paragraphs (4.1.2)(d) or (4.1.2)(e) above is made or any action is brought against any Dealer or any of the Dealer’s Related Parties in respect of which recovery may be sought from the Issuer and/or the Guarantor, as the case may be, under this Clause 4.1, the relevant Dealer shall promptly notify the Issuer and/or the Guarantor, as the case may be, in writing but failure to do so will not relieve the Issuer or the Guarantor from any liability under this Agreement.  If any such allegation is made, the parties agree to consult in good faith with respect to the nature of the allegation.  Subject to paragraph (g) below, the Issuer or, as the case may be, the Guarantor may participate at its own expense in the defence of any action.

(g)                                  If it so elects within a reasonable time after receipt of the notice referred to in paragraph (f) above, the Issuer or, as the case may be, the Guarantor may, subject as provided below, assume the defence of the action with legal advisers chosen by it and approved by the relevant Dealer (such approval not to be unreasonably withheld or delayed).  Notwithstanding any such election a Dealer or any of the Dealer’s Related Parties may employ separate legal advisers reasonably acceptable to the Issuer and the Guarantor, and the Issuer or the Guarantor shall not be entitled to assume such defence and shall bear the reasonable fees and expenses of such separate legal advisers if:

(i)                                     the use of the legal advisers chosen by the Issuer or the Guarantor to represent the Dealer or any of the Dealer’s Related Parties would present such legal advisers with a conflict of interest;

12

(ii)                                  the actual or potential defendants in, or targets of, any such action include both the Dealer or any of the Dealer’s Related Parties and the Issuer or the Guarantor and the Dealer concludes that there may be legal defences available to it and/or other Relevant Parties which are different from or additional to those available to the Issuer or the Guarantor; or

(iii)                               the Issuer or the Guarantor has not employed legal advisers reasonably satisfactory to the Dealer to represent the Dealer or any of the Dealer’s Related Parties within a reasonable time after notice of the institution of such action.

(h)                                 If the Issuer or, as the case may be, the Guarantor assumes the defence of the action, the Issuer or, as the case may be, the Guarantor shall not be liable for any fees and expenses of legal advisers of the Dealer or any of the Dealer’s Related Parties incurred thereafter in connection with the action, except as stated in paragraph (g) above.

(i)                                     Neither the Issuer nor the Guarantor shall be liable in respect of any settlement of any action effected without its written consent, such consent not to be unreasonably withheld or delayed.  Neither the Issuer nor the Guarantor shall, without the prior written consent of the Dealer (such consent not to be unreasonably withheld or delayed), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim or action in respect of which recovery may be sought (whether or not the Dealer or any of the Dealer’s Related Parties is an actual or potential party to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each Dealer and any of the Dealer’s Related Parties from all liability arising out of such claim or action and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of a Dealer or any of the Dealer’s Related Parties.

4.1.3                     Expenses, stamp duties, amendments:  each of the Issuers and the Guarantor will:

(a)                                 Arranger’s expenses:  pay, or reimburse the Arranger for, all reasonable out-of-pocket costs and expenses (including (i) an amount equal to any United Kingdom value added tax but only to the extent the Arranger, or any other member of the group to which the Arranger belongs for value added tax purposes, reasonably determines that it is not entitled to recover (whether by credit or repayment) such value added tax and (ii) fees and disbursements of counsel to such Arranger) incurred by the Arranger in connection with the preparation, negotiation, printing, execution and delivery of this Agreement and all documents contemplated by this Agreement;

(b)                                 Dealers’ expenses:  pay, or reimburse each Dealer for, all reasonable out-of-pocket costs and expenses (including (i) an amount equal to any United Kingdom value added tax but only to the extent the relevant

Dealer, or any other member of the group to which that Dealer belongs for value added tax purposes, reasonably determines that it is not entitled to recover (whether by credit or repayment) such value added tax and (ii) fees and disbursements of counsel to such Dealer) incurred by such Dealer in connection with the enforcement or protection of its rights under this Agreement;

(c)                                  Stamp duties:  pay all stamp, registration and other similar taxes and duties (including any interest and penalties thereon or in connection therewith) which may be payable upon or in connection with the creation and issue of the Notes and the execution, delivery and performance of the Agreements and the Guarantee, except for any taxes payable regarding Luxembourg registration duties (droits d’enregistrement) due to a registration, submission or filing of the Agreements and the Guarantee where such registration, submission or filing is or was not required to maintain or preserve the rights of the Dealers under the Agreements and the Guarantee, and the Issuers shall jointly and severally indemnify each Dealer against any claim, demand, action, liability, damages, cost, loss or expense (including (i) an amount equal to any United Kingdom value added tax but only to the extent the relevant Dealer, or any other member of the group to which that Dealer belongs for value added tax purposes, reasonably determines that it is not entitled to recover (whether by credit or repayment) such value added tax and (ii) fees and disbursements of counsel to such Dealer)  which it may incur as a result or arising out of or in relation to any failure to pay or delay in paying any of the same;

(d)                                 Amendments:  notify each Dealer of any change in the identity of or the offices of the Issue and Paying Agent and any material change or amendment to or termination of the Agency Agreement or the Deed of Covenant or the Guarantee not later than five days prior to the making of any such change or amendment or such termination; and it will not permit to become effective any such change, amendment or termination which could reasonably be expected to affect adversely the interests of any Dealer or the holder of any Notes then outstanding;

(b)                                 Redemption value:  the redemption value of each Note is not less than £100,000 (or an amount of equivalent value denominated wholly or partly in a currency other than Sterling), and no part of any Note may be transferred unless the redemption value of that part is not less than £100,000 (or such an equivalent amount); and

4.1.5                     Sanctions: the Issuers and the Guarantor will each ensure that proceeds raised in connection with the issue of any Notes will not directly or indirectly be lent,

14

contributed or otherwise made available to any person or entity (whether or not related to any Issuer or the Guarantor) for the purpose of financing the activities of any person or entity or for the benefit of any country currently the subject of any Sanctions, except and only as permitted by applicable law.

4.2                               Compliance

4.3                               Selling restrictions

4.4                               Dealers’ obligations several

The obligations of each Dealer contained in this Agreement are several.

4.5                               Status of Arranger

In relation to each issue of Notes, it shall be a condition precedent to the purchase thereof by any Dealer that (a) the representations and warranties in Clause 3.1 shall be true and correct in all material respects on each date upon which an agreement for the sale of Notes is made hereunder and on the date on which such Notes are issued and that (b) there is no other material breach of any of the obligations of the relevant Issuer or the Guarantor or either of them under any of the Agreements, the Notes or the Guarantee and that (c) the Dealer having received (in a form satisfactory to the Dealer) a duly executed or a conformed copy of the agreement between the relevant Issuer and the ICSDs with respect to the settlement in the ICSDs of New Global Notes.

6.1                               Termination

The Issuers may terminate the appointment of any Dealer, and any Dealer may resign, on not less than ten days’ written notice to the relevant Dealer or the Issuers, as the

16

case may be.  The Issuers shall promptly inform the other Dealer(s), the Guarantor and the Issue and Paying Agent of any such termination or resignation.  The rights and obligations of each party hereto shall not terminate in respect of any rights or obligations accrued or incurred before the date on which such termination takes effect and the provisions of sub-clause 4.1.2 and 4.1.3 shall survive termination of this Agreement and delivery against payment for any of the Notes.

6.2                               Additional Dealers

Nothing in this Agreement shall prevent the Issuers from appointing one or more additional Dealers upon the terms of this Agreement provided that any additional Dealer shall have first confirmed acceptance of its appointment upon such terms in writing to the Issuers in substantially the form of the letter set out in Schedule 5, whereupon it shall become a party to this Agreement vested with all the authority, rights, powers, duties and obligations as if originally named as a Dealer hereunder.  The Issuers shall promptly inform the other Dealer(s), the Guarantor and the Issue and Paying Agent of any such appointment.  The Issuers and the Guarantor hereby agrees to supply to such additional Dealer, upon such appointment, such legal opinions as are specified in paragraph 6 of Schedule 1, if requested, or reliance letters in respect thereof.

7.                                      NOTICES

All notices and other communications hereunder shall, save as otherwise provided in this Agreement, be made in writing and in English (by letter, fax or email) and shall be sent to the intended recipient at the address, fax number or email address and marked for the attention of the person (if any) from time to time designated by that party to the other parties hereto for such purpose.  The initial address, fax number and email address so designated by each party are set out in the Programme Summary.

7.2                               Effectiveness

Any communication from any party to any other under this Agreement shall be effective upon receipt by the addressee, provided that any such notice or other communication which would otherwise take effect after 4.00 p.m. on any particular day shall not take effect until 10.00 a.m. on the immediately succeeding business day in the place of the addressee.

7.3                               Assignment

If, at any time, any Dealer shall transfer all or substantially all of its euro-commercial paper business to any affiliate then, on the date such transfer becomes effective, such affiliate shall become the successor to the relevant Dealer under this Agreement without the execution or filing of any paper or any further act on the part of the parties hereto so that the Issuers and the Guarantor and such affiliate shall acquire and become subject to the same rights and obligations between themselves as if they had entered into an agreement in the form (the relevant changes having been made) of this Agreement.  After the said effective date all references in this Agreement to the relevant Dealer shall be deemed to be references to such affiliate.  The relevant Dealer

17

shall, as soon as reasonably practicable, give notice of any such transfer to the Issuers.  In this Clause 7.3, “affiliate” means, in relation to any person, any entity controlled, directly or indirectly, by such person, any entity that controls, directly or indirectly, such person, or any entity under common control with such person.  For this purpose “control” of any entity or person means ownership of a majority of the voting power of the entity or person.

The courts of England have exclusive jurisdiction to settle any dispute (a “Dispute”), arising from or connected with this Agreement (including a dispute regarding the existence, validity or termination of this Agreement or any non-contractual obligation arising out of or in connection with this Agreement) or the consequences of its nullity.

9.3                               Appropriate forum

The parties agree that the courts of England are the most appropriate and convenient courts to settle any Dispute and, accordingly, that they will not argue to the contrary.

9.4                               Rights of the Dealers to take proceedings outside England

Clause 9.2 (English courts) is for the benefit of the Dealers only.  As a result, nothing in this Clause 9 (Law and jurisdiction) prevents the Dealers from taking proceedings relating to a Dispute (“Proceedings”) in any other courts with jurisdiction.  To the extent allowed by law, the Dealers may take concurrent Proceedings in any number of jurisdictions.

9.5                               Process agent

Each Issuer and the Guarantor agrees that the documents which start any Proceedings and any other documents required to be served in relation to those Proceedings may be served on it by being delivered to Ecolab Limited at P.O Box 11, Winnington Avenue, Northwich, Cheshire, United Kingdom CW8 4DX or, if different, its registered office for the time being or at any address of the relevant Issuer or the Guarantor in Great Britain at which process may be served on it in accordance with The Companies Act 2006.  If such person is not or ceases to be effectively appointed to accept service of process on behalf of the Issuers and the Guarantor, the Issuers and the Guarantor shall, on the written demand of any Dealer addressed and delivered to

18

the Issuers and the Guarantor appoint a further person in England to accept service of process on its behalf and, failing such appointment within 15 days, any Dealer shall be entitled to appoint such a person by written notice addressed to the Issuers and the Guarantor and delivered to the Issuers and the Guarantor.  Nothing in this paragraph shall affect the right of any Dealer to serve process in any other manner permitted by law.  This clause applies to Proceedings in England and to Proceedings elsewhere.

9.                                      LAW AND JURISDICTION

9.1                               Governing law

This Agreement and any non-contractual obligations arising out of or in connection with it are governed by English law.

9.2                               Jurisdiction

The Issuer agrees for the benefit of the Calculation Agent that the courts of England shall have jurisdiction to hear and determine any suit, action or proceedings, and to settle any disputes, which may arise out of or in connection with this Agreement (including a dispute regarding the existence, validity or termination of this Agreement or any non-contractual obligation arising out of or in connection with this Agreement) or the consequences of its nullity (respectively, “Proceedings” and “Disputes”) and, for such purposes, irrevocably submits to the jurisdiction of such courts.

9.3                               Appropriate forum

The Issuer irrevocably waives any objection which it might now or hereafter have to the courts of England being nominated as the forum to hear and determine any Proceedings and to settle any Disputes, and agrees not to claim that any such court is not a convenient or appropriate forum.

9.4                               Process agent

The Issuer agrees that the process by which any Proceedings in England are begun may be served on it by being delivered to Ecolab Limited at P.O Box 11, Winnington Avenue, Northwich, Cheshire, United Kingdom CW8 4DX or, if different, its registered office for the time being.  If such person is not or ceases to be effectively appointed to accept service of process on behalf of the Issuer, the Issuer shall, on the written demand of the Calculation Agent addressed to the Issuer and delivered to the Issuer appoint a further person in England to accept service of process on its behalf and, failing such appointment within 15 days, the Calculation Agent shall be entitled to appoint such a person by written notice addressed to the Issuer and delivered to the

The submission to the jurisdiction of the courts of England shall not (and shall not be construed so as to) limit the right of the Calculation Agent to take Proceedings in any other court of competent jurisdiction, nor shall the taking of Proceedings in any one or more jurisdictions preclude the taking of Proceedings in any other jurisdiction (whether concurrently or not) if and to the extent permitted by law.
