person thereof may become subject, under the Act or the Exchange Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Underwriter Information (as defined below) or (ii) information in any Derived Information provided by such Underwriter (except to the extent that such untrue statements or errors contained therein are Seller-Provided Information or Prospectus Information), and shall reimburse the applicable HSBC Entity, promptly on demand, and any such director, officer or controlling person for any documented legal or other documented expenses reasonably incurred by such HSBC Entity, or any director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. “Underwriter Information” means the information set forth under the caption “Underwriting” in the Prospectus.

The foregoing indemnity agreement is in addition to any liability which the Underwriters may otherwise have to any HSBC Entity or any such director, officer or controlling person.

C. Promptly after receipt by any indemnified party under this Section 10 of notice of any claim or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party under this Section 10, promptly notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced by such failure; and provided, further, that the failure to notify any indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 10.

If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party, unless such indemnified party reasonably objects to such assumption on the ground that there may be legal defenses available to it which are different from or in addition to those available to such indemnifying party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, except to the extent provided in the next following paragraph, the indemnifying party shall not be liable to the indemnified party under this Section 10 for any fees and expenses of counsel subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation.

Any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless: (i) the employment thereof has been specifically authorized by the indemnifying party in writing; (ii) such indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ

separate counsel; or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to local counsel) at any time for all such indemnified parties, which firm shall be designated in writing by the Representative, if the indemnified parties under this Section 10 consist of the Underwriters or any of their controlling persons, or by the HSBC Entities, if the indemnified parties under this Section 10 consist of any of the HSBC Entities or any of the HSBC Entities’ directors, officers or controlling persons, but in either case reasonably satisfactory to the indemnified party.

Each indemnified party, as a condition of the indemnity agreements contained in Sections 10A and B, shall use its best efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which such 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 any claims that are the subject matter of such action.

D. If the indemnification provided for in this Section 10 shall for any reason be unavailable to hold harmless an indemnified party under Section 10A or B in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the HSBC Entities on the one hand and the Underwriters on the other from the offering of the Series 2005-3 Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the HSBC Entities on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations.

The relative benefits of the Underwriters and the HSBC Entities shall be deemed to be in such proportion so that the Underwriters are 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 on the cover page of the Prospectus.

The relative fault of the Underwriters and the HSBC Entities shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the HSBC Entities or by one of the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission and other equitable considerations.

The HSBC Entities and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 10D were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10D shall be deemed to include, for purposes of this Section 10D, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.

Each person, if any, who controls each Underwriter within the meaning of the Act or the Exchange Act shall have the same rights to contribution as each of the Underwriters and each director of a HSBC Entity, each officer of a HSBC Entity who signed the Registration Statement, and each person, if any, who controls a HSBC Entity within the meaning of the Act or the Exchange Act shall have the same rights to contribution as the applicable HSBC Entity.

Except in the case of any loss, claim, damage, liability or expense resulting solely from a breach of the Underwriter’s representation and warranty set forth in Section 3(a), (b) or (c) hereof, in no case shall any Underwriter be responsible for any amount in excess of the underwriting discount applicable to the Series 2005-3 Notes purchased by such Underwriter hereunder. 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.

E. The Underwriters severally confirm that the information set forth (i) in the Prospectus relating to market making and (ii) under the caption “Underwriting” in the Prospectus Supplement is correct and constitutes the only information furnished in writing to a HSBC Entity by or on behalf of the Underwriters specifically for inclusion in the Prospectus.

Section 11. Default by One or More of the Underwriters. If one or more of the Underwriters participating in the public offering of the Series 2005-3 Notes shall fail at the Closing Date to purchase the Series 2005-3 Notes which it is obligated to purchase hereunder (the “Defaulted Securities”), then the non-defaulting Underwriter(s) shall have the right, within 24 hours thereafter, to make arrangements to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Underwriter(s) have not completed such arrangements within such 24-hour period, then:

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Series 2005-3 Notes to be purchased pursuant to this Agreement, the non-defaulting

Underwriter(s) shall be obligated to purchase the full amount thereof, severally in the same proportions as the principal amount of Series 2005-3 Notes set forth opposite their respective names in Schedule 1 hereto, or

(ii) if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of the Series 2005-3 Notes to be purchased pursuant to this Agreement, this Agreement shall terminate, without any liability on the part of any non-defaulting Underwriter(s).

No action taken pursuant to this Section shall relieve the defaulting Underwriter(s) from the liability with respect to any default of such Underwriter(s) under this Agreement.

In the event of a default by an Underwriter as set forth in this Section, each of the Underwriters and the Seller shall have the right to postpone the Closing Date for a period not exceeding five Business Days in order that any required changes in the Registration Statement or Prospectus or in any other documents or arrangements may be effected.

Section 12. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Seller and HAFI prior to delivery of and payment for the Series 2005-3 Notes if prior to such time (i) trading in securities generally on the New York Stock Exchange or the National Association of Securities Dealers National Market System shall have been suspended or limited, or minimum prices shall have been established on such exchange or market system; (ii) a banking moratorium shall have been declared by either Federal, New York State authorities or the State of California; (iii) there shall have occurred any outbreak or material escalation of hostilities involving the United States of America where armed conflict or the declaration of war appears imminent, if, the effect of such event makes it, in the reasonable judgment of the Representative, impractical or inadvisable to proceed with the completion of the sale and payment for the Series 2005-3 Notes; or (iv) any other calamity or crisis having an effect on the U.S. financial markets that, in the reasonable judgment of the Representative, makes it impractical or inadvisable to proceed with the public offering or the delivery of the Securities as contemplated by the Registration Statement. Upon such notice being given, the parties to this Agreement shall (except for any liability arising before or in relation to such termination) be released and discharged from their respective obligations under this Agreement.

Section 13. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or contained in certificates of officers of the HSBC Entities submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Representative or controlling person of the Representative, or by or on behalf of the HSBC Entities or any officers, directors or controlling persons and shall survive delivery of any certificates to the Representative or any controlling person.

Section 14. 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 to the Underwriters at HSBC Securities (USA) Inc., 452

Fifth Avenue, 9^th Floor, New York, New York 10018, Attention: , Fax: (000) 000-0000; if sent to any HSBC Entity to 0000 Xxxxxxx Xxxx, Xxxxxxxx Xxxxxxx, Xxxxxxxx 00000, Attention: General Counsel, Fax: (000) 000-0000.

Section 15. Parties. This Agreement shall inure to the benefit of and be binding upon the Representative and the HSBC Entities, and their respective successors or assigns. Nothing expressed or mentioned in this Agreement is intended nor shall it be construed to give any person, firm or corporation, other than the parties hereto or thereto and their respective successors and the controlling persons and officers and directors referred to in Section 10 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties and their respective successors and said controlling persons and officers and directors and their heirs and legal representatives (to the extent of their rights as specified herein and therein) and except as provided above for the benefit of no other person, firm or corporation. No purchaser of Series 2005-3 Notes from the Representative shall be deemed to be a successor by reason merely of such purchase.

Section 16. No Advisory or Fiduciary Responsibility. Each of the HSBC Entities acknowledges and agrees that (a) the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the HSBC Entities with respect to the offering of the Series 2005-3 Notes contemplated hereby (including in connection with determining the terms of the offering) and not as a fiduciary to, or an agent of, any of the HSBC Entities or any other person, (b) the Underwriters owe the HSBC Entities only those obligations set forth in this Agreement and (c) the Underwriters may have interests that differ from those of the HSBC Entities. Additionally, neither the Representative nor any other Underwriter is advising the HSBC Entities or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The HSBC Entities shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby. Any review by the Underwriters of the HSBC Entities, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the HSBC Entities.

Section 17. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED IN ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS THEREOF. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

Section 18. Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but together they shall constitute but one instrument.

Section 19. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of or affect the meaning or interpretation of, this Agreement.

If the foregoing is in accordance with the Representative’s understanding of our agreement, please sign and return to us a counterpart hereof, whereupon this instrument along with all counterparts will become a binding agreement between the Representative, the Seller, HAFI, HACI and HSBC Finance in accordance with its terms.

Very truly yours,
