Any such Free Writing Prospectus consented to by the Representative or the Issuer and Citibank (South Dakota) is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Issuer agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

The Issuer will use its best efforts to arrange for the qualification of the Class 200[•]-[A][B][C][•] Notes for sale under the laws of such jurisdictions as the Underwriters may designate, will maintain such qualifications in effect so long as required for the distribution of the Class 200[•]-[A][B][C][•] Notes and will arrange for the determination of the legality of the Class 200[•]-[A][B][C][•] Notes for purchase by institutional investors.

The Underwriters will have received opinions from Davenport, Evans, Xxxxxxx & Xxxxx, L.L.P., special counsel to Citibank (South Dakota), and the General Counsel or an Associate General Counsel of Citibank (South Dakota) or other counsel satisfactory to the Representative substantially to the combined effect that:

(i) Citibank (South Dakota) has been duly organized as an association licensed as a national banking association and is validly existing and in good standing under the laws of the United States, is duly qualified to do business and is in good standing under the laws of each jurisdiction which requires such qualification wherein it owns or leases material properties or conducts material business, and has full power and authority to own its properties, to conduct its business as described in the Registration Statement and the Prospectus, to enter into and perform its obligations under each of the Basic Documents to which it is a party, to execute the Collateral Certificate, to cause the Issuer to enter into the Basic Documents to which it is a party, to cause the Issuer to issue the Class 200[•]-[A][B][C][•] Notes under the Indenture, and to consummate the transactions contemplated by the Basic Documents to which Citibank (South Dakota) is a party.

(ii) Each of the Basic Documents to which Citibank (South Dakota) is a party has been duly authorized, executed and delivered by Citibank (South Dakota). The increase in the Invested Amount of the Collateral Certificate effected by the issuance of the Class 200[•]-[A][B][C][•] Notes has been duly authorized by Citibank (South Dakota).

(iii) Neither the execution nor the delivery of any of the Basic Documents to which Citibank (South Dakota) is a party, nor the issuance and delivery of the Collateral Certificate and the Class 200[•]-[A][B][C][•] Notes, nor the increase in the Invested Amount of the Collateral Certificate effected by the issuance of the Class 200[•]-[A][B][C][•] Notes, nor the consummation of any of the transactions contemplated in the Basic Documents, nor the fulfillment of the terms thereof, did or will conflict with or violate, result in a material breach of or constitute a default under

(A)

any term or provision of the charter or bylaws of Citibank (South Dakota) or any federal statute or regulation currently applicable to Citibank (South Dakota) or any South Dakota statute or regulation currently applicable to Citibank (South Dakota), the Master Trust or the Issuer,

(B)

any term or provision of any order known to such counsel to be currently applicable to Citibank (South Dakota), the Master Trust or the Issuer of any court, regulatory body, administrative agency or governmental body having jurisdiction over Citibank (South Dakota), the Master Trust or the Issuer, as the case may be, or

(C)

any term or provision of any indenture or other agreement or instrument known to such counsel to which Citibank (South Dakota), the Master Trust or the Issuer is a party or by which any of them or any of their properties are bound.

(iv) Except as otherwise disclosed in the Prospectus or the Registration Statement, there is no pending or, to the best knowledge of such counsel, threatened action, suit or proceeding before any court or governmental agency, authority or body or any arbitrator with respect to the Master Trust, the Issuer, the Basic Documents or any of the transactions contemplated therein or with respect to Citibank (South Dakota) which, in the case of any such action, suit or proceeding with respect to Citibank (South Dakota) if adversely determined, would have a material adverse effect on the Master Trust, the Issuer, the holders of the Class 200[•]-[A][B][C][•] Notes, or upon the ability of Citibank (South Dakota) to perform its obligations under the Basic Documents to which it is a party. To the best knowledge of such counsel, there is no material contract, franchise or document relating to the Master Trust, the property conveyed to the Master Trust, the Issuer or the Issuer’s property other than as disclosed in the Prospectus. The statements included in the Registration Statement and the Prospectus describing statutes, legal proceedings, contracts and other documents relating to Citibank (South Dakota), the Accounts, the Receivables, the business of Citibank (South Dakota), the Master Trust and the Issuer fairly summarize the matters therein described.

(v) Such counsel has no reason to believe (A) that the Registration Statement, at the time it became effective, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) that the Prospectus as of its issue date or the Closing Date included or includes any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or (C) that the [information contained in Schedule IV hereto,] [this language is to be included when a preliminary term sheet is used in lieu of a preliminary prospectus and the use of a preliminary prospectus is not required] [Preliminary Prospectus considered together with the information contained in Schedule III hereto,] [this language is to be included when the use of a preliminary prospectus is required] including the documents referred to therein and the documents incorporated by reference into such documents, at the Pricing Time, when taken together as a whole, does not contain 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

under which they are made, not misleading (but such counsel need express no opinion as to the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Indenture Trustee or as to the financial statements or other financial data contained or incorporated by reference in or omitted from the Registration Statement or any amendment thereto or the Prospectus or any supplement thereto or as to statements regarding tax or ERISA matters). Such opinion may be limited to information relating to Citibank (South Dakota), its credit card business, the Accounts and the Receivables.

(vi) No approval, authorization, consent, order, registration, filing, qualification, license or permit of or with any court or governmental agency or body is required for the consummation by Citibank (South Dakota), the Master Trust or the Issuer (except that, with respect to the Master Trust and the Issuer, this opinion may be limited to any court or governmental agency or body of the State of South Dakota) of the transactions contemplated in the Basic Documents, except such as have been obtained under the Securities Act and such as may be required under the blue sky laws of any jurisdiction inside the United States in connection with the purchase and distribution of the Class 200[•]-[A][B][C][•] Notes by the Underwriters and such filings or other approvals (specified in such opinion) as have been made or obtained.

(vii) Citibank (South Dakota) or one of its affiliates is the sole owner of all right, title and interest in, and has good and marketable title to, the Accounts. With respect to all Receivables transferred by Citibank (South Dakota) to the Master Trust, at the time of such transfer, Citibank (South Dakota) was the sole owner of all right, title and interest in, and had good and marketable title to, such Receivables. The assignment of such Receivables, all documents and instruments relating thereto and all proceeds thereof to the Master Trust Trustee, pursuant to the Pooling and Servicing Agreement, vested in the Master Trust Trustee all interests which were purported to be conveyed thereby (except to the extent that the assignment of such Receivables is held by a court to constitute a grant of a security interest in such Receivables, as described in clause (x) below), free and clear of any liens, security interests or encumbrances except as specifically permitted pursuant to the Pooling and Servicing Agreement.

(viii) The Receivables constitute “accounts” as defined in the Uniform Commercial Code in effect in the State of South Dakota.

(ix) A Uniform Commercial Code financing statement with respect to the Certificateholders’ Interest in the Receivables transferred and to be transferred by Citibank (South Dakota) to the Master Trust and the proceeds thereof has been filed in the office of the South Dakota Secretary of State. No other filings or other actions, with respect to the Master Trust Trustee’s interest in such Receivables, are necessary to perfect and maintain the interest of the Master Trust Trustee in such Receivables, and proceeds thereof, against third parties, except that appropriate continuation statements must be filed at five-year intervals.

(x) The assignment of the Receivables, all documents and instruments relating thereto and all proceeds thereof to the Master Trust Trustee, pursuant to the Pooling and Servicing Agreement, is intended to be a sale and if a court concludes that it is a sale, such assignment transferred all the right, title and interest of Citibank (South Dakota) in and to such Receivables in existence on May 29, 1991 and all Receivables which have come into existence from May 29, 1991 to the date of such opinion to the Master Trust, free and clear of any Liens then existing or thereafter created, but subject to the rights of the Sellers as holders of the Sellers’ Certificates. With respect to Receivables which come into existence after the date of such opinion, such sale will transfer all of the right, title and interest of Citibank (South Dakota) in and to such Receivables to the Master Trust free and clear of any Liens, but subject to the rights of the Sellers as holders of the Sellers’ Certificates. The Pooling and Servicing Agreement and the transactions provided for by the Pooling and Servicing Agreement constitute a grant by Citibank (South Dakota) to the Master Trust Trustee of a valid security interest and, together with the filing of the financing statement referred to in clause (ix) above, create a first priority perfected security interest in the Receivables transferred and to be transferred by Citibank (South Dakota) to the Master Trust, all documents and instruments relating thereto and all proceeds thereof. In rendering such opinion counsel may take such exceptions as are appropriate and reasonably acceptable under the circumstances.

(xi) A Uniform Commercial Code financing statement with respect to the Indenture Trustee’s security interest in the Collateral has been filed in the office of the South Dakota Secretary of State.

(xii) Assuming that the Indenture constitutes a grant by the Issuer to the Indenture Trustee of a valid security interest and such security interest has attached upon filing of the financing statement referred to in clause (xi) above with the South Dakota Secretary of State, the Indenture Trustee will have a first priority perfected security interest in the Issuer’s rights in such Collateral to the extent a security interest may be perfected by filing such financing statement in the State of South Dakota. No other filings or other actions are necessary to perfect and maintain the Indenture Trustee’s security interest in the Collateral against third parties, except that appropriate continuation statements must be filed at five-year intervals. In rendering such opinion, counsel may take such exceptions as are appropriate and reasonable under the circumstances.

(xiii) The statements in the Prospectus under the heading “Legal aspects could affect the timing and amount of payments to you”, to the extent that they constitute statements of matters of law or legal conclusions with respect thereto, are correct in all material respects.

(xiv) The Class 200[•]-[A][B][C][•] Notes have been duly authorized and established by all action required on the part of Citibank (South Dakota).

In rendering such opinion, counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of South Dakota and the United States, to the extent deemed proper and stated in such opinion, upon the opinion of other counsel of good standing believed by such counsel to be reliable and acceptable to the Representative and counsel to the Representative, and (B) as to matters of fact, to the extent deemed proper and as stated therein, on certificates of responsible officers of Citibank (South Dakota), the Master Trust, the Issuer and public officials.

(e) Opinion of New York Counsel to the Issuer and Citibank (South Dakota). The Underwriters will have received an opinion of New York counsel to the Issuer and Citibank (South Dakota) substantially to the effect that:

(i) Each of the Basic Documents to which Citibank (South Dakota) is a party has been duly authorized, executed and delivered by Citibank (South Dakota). Each of the Basic Documents to which Citibank (South Dakota) or the Issuer is a party (other than this Agreement) constitutes the legal, valid and binding agreement of Citibank (South Dakota) or the Issuer, as the case may be, enforceable in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium and other laws affecting creditors’ rights generally from time to time in effect and to the application of general principles of equity).

(ii) The Collateral Certificate has been duly authorized and executed by Citibank (South Dakota) and Citibank (Nevada) in accordance with the terms of the Pooling and Servicing Agreement. The Collateral Certificate is validly issued and outstanding, enforceable in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium and other laws affecting creditors’ rights generally from time to time in effect and to the application of general principles of equity) and is entitled to the benefits of the Pooling and Servicing Agreement.

(iii) The Class 200[•]-[A][B][C][•] Notes have been duly authorized and established in conformity with the Indenture and, when executed and authenticated in accordance with the terms of the Indenture and delivered to and paid for by the Underwriters pursuant to this Agreement, will be validly issued and outstanding, enforceable in accordance with their terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium and other laws affecting creditors’ rights generally from time to time in effect and to the application of general principles of equity) and will be entitled to the benefits of the Indenture.

(iv) Neither the execution nor the delivery of any of the Basic Documents to which Citibank (South Dakota) or the Issuer is a party nor the issuance and delivery of the Collateral Certificate or the Class 200[•]-[A][B][C][•] Notes, nor any increase in the Invested Amount of the Collateral Certificate, nor the consummation of any of the transactions contemplated by the Basic Documents, nor the fulfillment of the terms thereof, will conflict with or violate, result in a

material breach of or constitute a default under any Federal or New York statute or regulation currently applicable to Citibank (South Dakota), the Master Trust or the Issuer.

(v) No approval, authorization, consent, order, registration, filing, qualification, license or permit of or with any Federal or New York court or governmental body or agency is required for the consummation by Citibank (South Dakota), the Master Trust or the Issuer of the transactions contemplated by the Basic Documents or in connection with the issuance of the Collateral Certificate or the Class 200[•]-[A][B][C][•] Notes, except such as have been obtained under the Securities Act and such as may be required under the blue sky laws of any jurisdiction inside the United States in connection with the purchase and distribution of the Class 200[•]-[A][B][C][•] Notes by the Underwriters and such filings or approvals as have been made and obtained and except where the failure to obtain any thereof would not have a material adverse effect on the ability of Citibank (South Dakota), the Master Trust or the Issuer to perform its respective obligations under any of the Basic Documents.

(vi) The Registration Statement has become effective under the Securities Act. Any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b). To the best knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any notice that would prevent its use has been issued, and no proceedings for that purpose have been instituted or threatened; the Registration Statement, at the time it became effective, and the Prospectus as of the date of any such supplement and as of the date of such opinion, appeared on their faces to be appropriately responsive in all material respects to the requirements of the Securities Act, the Trust Indenture Act and the respective rules and regulations of the Commission thereunder (but such counsel need express no opinion as to the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Indenture Trustee or as to the financial statements or other financial data contained or incorporated by reference in or omitted from the Registration Statement or any amendment thereto or the Prospectus or any supplement thereto or as to statements regarding tax or ERISA matters).

(vii) Such counsel has no reason to believe (A) that the Registration Statement, at the time it became effective, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) that the Prospectus as of its issue date or the Closing Date included or includes any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or (C) that the [information contained in Schedule IV hereto,] [this language is to be included when a preliminary term sheet is used in lieu of a preliminary prospectus and the use of a preliminary prospectus is not required] [Preliminary Prospectus considered

together with the information contained in Schedule III hereto,] [this language is to be included when the use of a preliminary prospectus is required] including the documents referred to therein and the documents incorporated by reference into such documents, at the Pricing Time, when taken together as a whole, does not contain 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 under which they are made, not misleading (but such counsel need express no opinion as to the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Indenture Trustee or as to the financial statements or other financial data contained or incorporated by reference in or omitted from the Registration Statement or any amendment thereto or the Prospectus or as to statements regarding tax or ERISA matters). Such counsel has discussed the opinion described in this clause with the counsel giving the opinion referred to in clause (d).

(viii) The Pooling and Servicing Agreement is not required to be qualified under the Trust Indenture Act. The Indenture has been duly qualified under the Trust Indenture Act. Neither the Master Trust nor the Issuer is required to be registered under the Investment Company Act of 1940, as amended.

(ix) The assignment of the Receivables, all documents and instruments relating thereto and all proceeds thereof to the Master Trust Trustee, pursuant to the Pooling and Servicing Agreement, is intended to be a sale and if a court concludes that it is a sale, such sale transferred all the rights, titles and interests of Citibank (South Dakota) in and to such Receivables in existence on May 29, 1991 and all Receivables that have come into existence from May 29, 1991 to the date of such opinion to the Master Trust, free and clear of any Liens then existing or thereafter created, but subject to the rights of the Seller as holder of the Seller’s Certificate. With respect to Receivables that come into existence after the date of such opinion, such sale will transfer all of the right, title and interest of Citibank (South Dakota) in and to such Receivables to the Master Trust free and clear of any Liens, but subject to the rights of the Seller as holder of the Seller’s Certificate. The Pooling and Servicing Agreement and the transactions provided for by the Pooling and Servicing Agreement constitute a grant by Citibank (South Dakota) to the Master Trust Trustee of a valid security interest and create a valid security interest in the Receivables, all documents and instruments relating thereto and all proceeds thereof. In rendering such opinion counsel may take such exceptions as are appropriate and reasonably acceptable under the circumstances.

(x) The Collateral Certificate is either a “certificated security” within the meaning of Section 8-102(a)(4) of the New York Uniform Commercial Code (the “New York UCC”), or a “general intangible” within the meaning of Section 9-102(a)(42) of the New York UCC. The Indenture and the applicable terms document are effective to create a valid security interest in favor of the Indenture Trustee, for the benefit of the secured parties described in the Indenture, in the Issuer’s right, title and interest in and to (a) the Collateral Certificate and the proceeds (as defined in Section 9-102(a)(64) of the New York UCC) thereof, and

(b) the other Collateral consisting of “accounts”, “documents”, “general intangibles”, “instruments” and “investment property” within the meaning of the New York UCC to the extent that such Collateral is listed in the description of Collateral in the Indenture and the applicable terms document. If the Collateral Certificate is a “certificated security” within the meaning of Section 8-102(a)(4) of the New York UCC, the delivery on or before the date on which the Indenture was executed and delivered to, and continued possession thereafter by, the Indenture Trustee of the Collateral Certificate in the State of New York will perfect the security interest in the Collateral Certificate and, if the Collateral Certificate is accompanied by an effective endorsement (whether in the name of the Indenture Trustee or in blank), the Indenture Trustee will have the status of a protected purchaser with respect to the Collateral Certificate. In rendering such opinion counsel may take such exceptions as are appropriate and reasonably acceptable under the circumstances.

(xi) The Basic Documents conform in all material respects to the descriptions thereof contained in the Registration Statement and the Prospectus.

(xii) The statements in the Prospectus under the heading “Legal aspects could affect the timing and amount of payments to you” (other than those under the subheading “Changes in consumer protection laws may impede Citibank (South Dakota)’s collection efforts”), to the extent that they constitute statements of matters of law or legal conclusions with respect thereto, are correct in all material respects.

In rendering such opinion, counsel may rely (A) as to matters involving the application of laws other than the General Corporation Law of the State of Delaware or laws of any jurisdiction other than the State of New York and the United States, to the extent deemed proper and stated in such opinion, upon the opinion of other counsel of good standing believed by such counsel to be reliable and acceptable to the Representative and counsel to the Representative, and (B) as to matters of fact, to the extent deemed proper and as stated therein, on certificates of responsible officers of Citibank (South Dakota), the Master Trust, the Issuer and public officials.

(f) Underwriters’ Counsel’s Opinion. The Underwriters will have received an opinion or opinions of Cravath, Swaine & Xxxxx LLP, special counsel to the Underwriters, with respect to the issuance and sale of the Class 200[•]-[A][B][C][•] Notes and the Basic Documents and such other related matters as the Underwriters may reasonably require.

(g) Master Trust Trustee Opinion. The Underwriters will have received an opinion or opinions of Xxxxxxxxx Xxxxxxx LLP, counsel to the Master Trust Trustee substantially to the following effect:

(i) The Master Trust Trustee has been duly incorporated and is validly existing as a banking corporation under the laws of the State of New York, and has the power and authority (corporate and other) to enter into, and to take all action required of it under the Base P&S and the Series 2000 Supplement.

(ii) Each of the Base P&S and the Series 2000 Supplement has been duly authorized, executed and delivered by the Master Trust Trustee and each constitutes a legal, valid and binding agreement of the Master Trust Trustee, enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium or other laws relating to or affecting the enforcement of rights of creditors generally, the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and the limitations on rights to indemnification and contribution which may be imposed by applicable law or equitable principles.

(iii) The Collateral Certificate has been duly authenticated and delivered by the Master Trust Trustee.

(iv) The execution and delivery by the Master Trust Trustee of each of the Base P&S and the Series 2000 Supplement and the performance by the Master Trust Trustee of the terms of each do not conflict with or result in a violation of (A) any law or any regulation of the United States of America or the State of New York governing the banking or trust powers of the Master Trust Trustee, or (B) the articles of incorporation or bylaws of the Master Trust Trustee.

(v) No approval, authorization or other action by, or filing with, any governmental authority of the United States of America or the State of New York having jurisdiction over the banking or trust powers of the Master Trust Trustee is required in connection with its execution and delivery of each of the Base P&S and the Series 2000 Supplement or the performance by the Master Trust Trustee of the terms of each of the Base P&S and the Series 2000 Supplement.

(h) Issuer Delaware Opinion. The Underwriters will have received an opinion of Xxxxxxxx, Xxxxxx & Finger P.A., special Delaware counsel to the Issuer, substantially to the following effect:

(i) The Issuer has been duly formed and is validly existing as a statutory trust under Delaware Statutory Trust Act, 12 Del. C. § 3801, et seq. (the “Delaware ST Act”), and has the power and authority under the Trust Agreement and the Delaware ST Act to execute, deliver and perform its obligations under the Basic Documents to which it is a party.

(ii) The Basic Documents to which the Issuer is a party have been duly authorized, executed and delivered by the Issuer and the Class 200[•]-[A][B][C][•] Notes have been duly authorized by the Issuer.

(iii) The Trust Agreement is a legal, valid and binding obligation of the parties thereto, enforceable against the parties thereto, in accordance with its terms subject to (A) applicable bankruptcy, insolvency, moratorium, receivership,

reorganization, fraudulent transfer and similar laws relating to and affecting the rights and remedies of creditors generally, (B) principles of equity, including applicable law relating to fiduciary duties (regardless of whether considered and applied in a proceeding in equity or at law), and (C) applicable public policy with respect to the enforceability of provisions relating to indemnification or contribution.

(iv) Neither the execution, delivery and performance by the Issuer of the Basic Documents to which it is a party, nor the consummation by the Issuer of any of the transactions contemplated thereby, requires the consent or approval of, the withholding of objection on the part of, the giving of notice to, the filing, registration or qualification with, or the taking of any other action in respect of, any governmental authority or agency of the State of Delaware, other than the filing of the Certificate of Trust of the Issuer with the Secretary of State (which Certificate of Trust has been duly filed).

(v) Neither the execution, delivery and performance by the Issuer of the Basic Documents to which it is a party, nor the consummation by the Issuer of the transactions contemplated thereby, is in violation of the Trust Agreement or of any law, rule or regulation of the State of Delaware applicable to the Issuer.

(vii) Assuming that the Indenture constitutes a grant by the Issuer to the Indenture Trustee of a valid security interest and such security interest has attached upon filing of the financing statement referred to in clause (vi) above with the Delaware Secretary of State, the Indenture Trustee will have a first priority perfected security interest in the Issuer’s rights in such Collateral to the extent a security interest may be perfected by filing such financing statement in the State of Delaware. No other filings or other actions are necessary to perfect and maintain the Indenture Trustee’s security interest in the Collateral against third parties, except that appropriate continuation statements must be filed at five-year intervals. In rendering such opinion, counsel may take such exceptions as are appropriate and reasonable under the circumstances.

(viii) After due inquiry as of a specified recent date, limited to, and solely to the extent disclosed thereupon, court dockets for active cases of the Court of Chancery of the State of Delaware in and for New Castle County, Delaware, of the Superior Court of the State of Delaware in and for New Castle County, Delaware, and of the United States District Court sitting in the State of Delaware, such counsel is not aware of any legal or governmental proceeding pending against the Issuer.

(ii) The Trust Agreement has been duly authorized, executed and delivered by the Issuer Trustee.

(iii) Neither the execution, delivery and performance by the Issuer Trustee of the Trust Agreement, nor the consummation of any of the transactions by the Issuer Trustee contemplated thereby, requires the consent or approval of, the withholding of objection on the part of, the giving of notice to, the filing, registration or qualification with, or the taking of any other action in respect of, any governmental authority or agency of the State of Delaware or the United States of America governing the banking or trust powers of the Issuer Trustee.

(iv) Neither the execution, delivery and performance by the Issuer Trustee of the Trust Agreement, nor the consummation of any of the transactions by the Issuer Trustee contemplated thereby, is in violation of the charter or bylaws of the Issuer Trustee or of any law, governmental rule or regulation of the State of Delaware or of the United States of America governing the banking or trust powers of the Issuer Trustee or, to our knowledge, without independent investigation, of any indenture, mortgage, bank credit agreement, note or bond purchase agreement, long-term lease, license or other agreement or instrument to which it is a party or by which it is bound or, to our knowledge, without independent investigation, of any judgment or order applicable to the Issuer Trustee.

(v) To such counsel’s knowledge, without independent investigation, there are no proceedings pending or threatened against the Issuer Trustee in any court or before any governmental authority, agency or arbitration board or tribunal which, individually or in the aggregate, would have a material adverse effect on the right, power and authority of the Issuer Trustee to enter into or perform its obligations under the Trust Agreement.

(iii) The Class 200[•]-[A][B][C][•] Notes have been duly authenticated and delivered by or on behalf of the Indenture Trustee.

(iv) The execution and delivery of each of the Basic Documents to which the Indenture Trustee is a party and the performance by the Indenture Trustee of the terms of each do not conflict with or result in a violation of (A) any law or regulation of the United States of America or the State of New York governing the banking or trust powers of the Indenture Trustee, or (B) the articles of incorporation or bylaws of the Indenture Trustee.

(v) No approval, authorization or other action by, or filing with, any governmental authority of the United States of America or the State of New York having jurisdiction over the banking or trust powers of the Indenture Trustee is required in connection with its execution and delivery of the Basic Documents to which it is a party or the performance by the Indenture Trustee of the terms of the Basic Documents to which it is a party.

SECTION 8. Indemnification and Contribution.

(a) The Issuer and Citibank (South Dakota), jointly and severally, agree to indemnify and hold harmless each Underwriter and each person who controls any Underwriter within the meaning of the Securities Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Class 200[•]-[A][B][C][•] Notes as originally filed or in any amendment thereof, or in any Preliminary Prospectus, the Basic Prospectus, the Prospectus, any Issuer Free Writing Prospectus or the pricing information on Schedule III, [or the information contained in the final term sheet required to be prepared and

filed pursuant to Section 5(b) hereto,] [this language is to be included when a preliminary term sheet is used in lieu of a preliminary prospectus and the use of a preliminary prospectus is not required] or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agree to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, that the Issuer and Citibank (South Dakota) will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuer or Citibank (South Dakota) by or on behalf of any Underwriter specifically for use in connection with the preparation thereof. The Issuer’s obligation to indemnify the Underwriters will be limited to Finance Charge Collections from the Collateral Certificate received by the Issuer after making all required payments and required deposits under the Indenture with respect to the Indenture Trustee’s fees and expenses, principal, interest and reimbursements with respect to the Notes, and payments to Derivative Counterparties. This indemnity agreement will be in addition to any liability which the Issuer or Citibank (South Dakota) may otherwise have.

(b) Each Underwriter, severally, agrees to indemnify and hold harmless the Issuer, Citibank (South Dakota), each of their directors, each of the officers who signs the Registration Statement, and each person who controls Citibank (South Dakota) within the meaning of the Securities Act, to the same extent as the foregoing indemnities from the Issuer and Citibank (South Dakota) to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Issuer or Citibank (South Dakota) by or on behalf of such Underwriter specifically for use in the preparation of the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Issuer and Citibank (South Dakota) acknowledge that the statements relating to the Underwriters and this Agreement set forth in the second sentence under the heading “Risk Factors—Your ability to resell Notes may be limited” and the statements in the fourth paragraph under the heading “Plan of Distribution” in [the Preliminary Prospectus and] [this language to be included when the use of a preliminary prospectus is required] the Basic Prospectus and the statements in the first paragraph (including the information in the table), and the second, third, fifth, sixth and seventh paragraphs under the heading “Underwriting” in [the Preliminary Prospectus and] [this language to be included when the use of a preliminary prospectus is required] the Prospectus Supplement [and the information set forth opposite “Underwriters and allocations”, “Underwriters’ concession”, and “Reallowance concession” in (i) the Free Writing Prospectus included in Schedule II hereto and (ii) the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto] [this language to be included when a preliminary term sheet is used in lieu of a preliminary prospectus and the use of a preliminary prospectus is not required] constitute the only information furnished in writing by or on behalf of any Underwriter for inclusion in any Issuer Free Writing Prospectus, Preliminary Prospectus, the Basic Prospectus or the Prospectus, and each Underwriter confirms that such statements are correct.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be

made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 8. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled, jointly with any other indemnifying party similarly notified, to appoint counsel satisfactory to such indemnified party to represent the indemnified party in such action; provided, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties will have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to appoint counsel to defend such action and approval by the indemnified party of such counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party has employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party will not be liable for the expenses of more than one separate counsel, approved by the Underwriters in the case of paragraph (a) of this Section 8, representing the indemnified parties under such paragraph (a) who are parties to such action), (ii) the indemnifying party has not employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability will be only in respect of the counsel referred to in such clause (i) or (iii).

(d) To provide for just and equitable contribution in circumstances in which the indemnification provided for in paragraph (a) of this Section 8 is due in accordance with its terms but is for any reason held by a court to be unavailable on grounds of policy or otherwise, the Issuer and Citibank (South Dakota), on the one hand, and the Underwriters, on the other, will contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) to which the Issuer, Citibank (South Dakota) and the Underwriters may be subject in such proportion so that the Underwriters will be responsible for that portion represented by the percentage that the underwriting discount appearing on the cover page of the Prospectus bears to the public offering price appearing thereon and the Issuer and Citibank (South Dakota) will be jointly and severally responsible for the balance; provided, that (i) in no case will any Underwriter (except as may be provided in the agreement among underwriters relating to the offering of the Class 200[•]-[A][B][C][•] Notes) be responsible for any amount in excess of the underwriting discount applicable to the Class 200[•]-[A][B][C][•] Notes purchased by such Underwriter hereunder and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls any Underwriter within the meaning of the Securities Act will have the same rights to contribution as such Underwriter, and each person who controls the Issuer or Citibank (South Dakota) within the

meaning of the Securities Act, each officer of the Issuer or Citibank (South Dakota) who has signed the Registration Statement and each director of Citibank (South Dakota) will have the same rights to contribution as the Issuer and Citibank (South Dakota), as the case may be, subject in each case to clauses (i) and (ii) of this paragraph (d). Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against any other party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this paragraph (d).

SECTION 9. Termination. This Agreement will be subject to termination in the absolute discretion of the Underwriters, by notice given to the Issuer and Citibank (South Dakota) before delivery of and payment for the Class 200[•]-[A][B][C][•] Notes, if before such time (i) trading in securities generally on the New York or Irish Stock Exchange will have been suspended or limited, (ii) a banking moratorium will have been declared by Federal, New York, or South Dakota state authorities or (iii) there will have occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States of America, Japan or Europe is such as to make it, in the judgment of the Underwriters, impractical or inadvisable to market the Class 200[•]-[A][B][C][•] Notes.

SECTION 10. Representations and Indemnities To Survive. The respective agreements, representations, warranties, indemnities and other statements of the Issuer, Citibank (South Dakota) or the officers of each of them and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Issuer, Citibank (South Dakota) or any of the officers, directors or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Class 200[•]-[A][B][C][•] Notes.

The Issuer and Citibank (South Dakota) hereby acknowledge that (a) the purchase and sale of the Class 200[•]-[A][B][C][•] pursuant to this Agreement is an arm’s-length commercial transaction between the Issuer and Citibank (South Dakota), on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Issuer and Citibank (South Dakota) and (c) the Issuer and Citibank (South Dakota)’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Issuer and Citibank (South Dakota) agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Issuer or Citibank (South Dakota) on related or other matters). The Issuer and Citibank (South Dakota) agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuer or Citibank (South Dakota), in connection with such transaction or the process leading thereto.

The headings in this Agreement are for purposes of reference only and will not limit or otherwise affect the meaning hereof.

SECTION 17. Default by an Underwriter. If any one or more Underwriters fail to purchase and pay for any of the Class 200[•]-[A][B][C][•] Notes agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase constitutes a default in the performance of its or their obligations under this Agreement, the remaining Underwriters will be obligated severally to take up and pay for (in the respective proportions which the amount of Class 200[•]-[A][B][C][•] Notes set forth opposite their names in Schedule I hereto bears to the aggregate amount of Class 200[•]-[A][B][C][•] Notes set forth opposite the names of all the remaining Underwriters) the Class 200[•]-[A][B][C][•] Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, that if the aggregate amount of Class 200[•]-[A][B][C][•] Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase exceeds 10% of the aggregate principal amount of Class 200[•]-[A][B][C][•] Notes set forth in Schedule I hereto, the remaining Underwriters will have the right to purchase all, but will not be under any obligation to purchase any, of the Class 200[•]-[A][B][C][•] Notes, and if such nondefaulting Underwriters do not purchase all the Class 200[•]-[A][B][C][•] Notes, this Agreement will terminate without liability to any nondefaulting Underwriter, the Issuer or Citibank (South Dakota). In the event of a default by any Underwriter as set forth in this Section 17, the Closing Date will be postponed for such period, not exceeding seven days, as the Underwriters determine in order that the required changes in the Registration Statement and the Prospectus (and any supplements thereto) or in any other documents or arrangements may be effected.

SECTION 19. No Personal Liability of Issuer Trustee.

SECTION 20. No Petition. Each Underwriter agrees that it will not, before the date that is one year and one day after the date on which all notes or securities issued by the Issuer have been paid in full, acquiesce, petition or otherwise invoke or cause the Issuer to invoke the process of any governmental authority for the purpose of commencing or sustaining a case against the Issuer under any Federal or state bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Issuer or any substantial part of its property or ordering the winding-up or liquidation of the Issuer.

If you are in agreement with the foregoing, please sign four counterparts hereof and return one to Citibank (South Dakota) and the Issuer, whereupon this letter and your acceptance will become a binding agreement among Citibank (South Dakota), the Issuer and the several Underwriters.
