The undersigned, HECO Capital Trust III (the “Trust”), a statutory trust created under the Statutory Trust Act of the State of Delaware (Title 12, Chapter 38 of the Delaware Code, 12 Del. C. Section 3801 et seq.) (the “Delaware Act”), proposes to issue and sell to the several underwriters named in Schedule I hereto (the “Underwriters,” which term, when the context permits, shall also include any underwriters substituted as hereinafter in Section 11 hereof provided), for whom you are acting as representatives (in such capacity, you shall hereinafter be referred to as the “Representatives”), 2,000,000 of its 6.500% Cumulative Quarterly Income Preferred Securities, Series 2004 (liquidation preference $25 per preferred security), representing preferred undivided beneficial interests in the assets of the Trust (the “Trust Preferred Securities”), as follows:

Such registration statement, as amended at the time it (or the most recent post-effective amendment thereto) became effective under the Securities Act, including the information deemed to be part thereof pursuant to Rule 430A(b) under the Securities Act, is hereinafter referred to as the “Registration Statement.” The prospectus constituting a part of the Registration Statement, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, in the form transmitted for filing to the Commission pursuant to Rule 424(b)(1) or (b)(4) under the Securities Act and as it may thereafter be amended or supplemented pursuant to Section 6(d) hereof, is hereinafter referred to as the “Prospectus” (except that if any revised prospectus shall be provided to the Underwriters by the Offerors for use in connection with the offering of the Securities that differs from the Prospectus transmitted for filing to the Commission pursuant to

(r) The Companies and the Trust will furnish the Underwriters with additional conformed copies of such opinions, certificates, letters and documents as may be reasonably requested.

If any of the conditions specified in this Section 7 shall not have been fulfilled, this Underwriting Agreement may be terminated by the Underwriters on or prior to the Closing Date upon notice thereof to the Offerors. Any such termination shall be without liability of any party to any other party, except as otherwise provided in Sections 6(g) and Section 10 hereof.

Section 8. Condition to the Obligations of the Offerors. The obligations of the Companies and the Trust hereunder shall be subject to the condition that no stop order suspending the effectiveness of the Registration Statement shall be in effect at or prior to the Closing Date, and no proceedings for that purpose shall be pending before, or threatened by, the Commission on the Closing Date. In case such condition shall not have been fulfilled, this Underwriting Agreement may be terminated by the Offerors upon notice thereof to the Representatives. Any such termination shall be without liability of any party to any other party, except as otherwise provided in Sections 6(g) and 10 hereof.

Section 9. Indemnification and Contribution. (a) The Companies and the Trust jointly and severally will indemnify and hold harmless each Underwriter, and each person, if any, who controls each Underwriter within the meaning of Section 15 of the Securities Act from and against any and all losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as amended, or 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, or arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus or in the Prospectus, as it may be amended or supplemented, or any omission or alleged omission to state therein a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading, and will reimburse such Underwriter for any legal or other expenses reasonably incurred by each Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither any Company nor the Trust shall 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 omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Information; provided further, however, that neither the Companies nor the Trust shall be required to reimburse any Underwriter or such person for fees and expenses of counsel other than one counsel for all Underwriters and one counsel for all Underwriters in each jurisdiction in which proceedings are or are threatened to be brought or of which matters of law are or may be at issue, unless and to the extent that there are actual or potential conflicts of interest between or among Underwriters or defenses available to one or more Underwriters that are not available to other Underwriters; provided further, however, that the indemnification contained in this Section 9(a) with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) on account of any such loss, claim, damage, liability or expense arising from the sale of the Trust Preferred Securities by such Underwriter to any person if the Companies and the Trust have established that a copy of the Prospectus was not delivered or sent to such person within the time required by the Securities Act and the rules and regulations thereunder, and the untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in such Preliminary Prospectus was corrected in the Prospectus, provided that the Offerors have delivered the Prospectus to the several Underwriters in requisite quantity on a timely basis to permit such delivery or sending.

(b) Each Underwriter will indemnify and hold harmless the Companies and the Trust, their respective directors and officers who signed the Registration Statement and each person, if any, who controls any of the Companies or the Trust within the meaning of Section 15 of the Securities Act from and against any and all losses, claims, damages or liabilities to which the Companies or the Trust may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as amended, or 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, or arise out of or are based upon any untrue statement or alleged untrue statement of

a material fact contained in any Preliminary Prospectus or in the Prospectus, as it may be amended or supplemented, or any omission or alleged omission to state therein a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Information, and will reimburse the Companies and the Trust for any legal or other expenses reasonably incurred by the Companies and the Trust in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under Section 9(a) or 9(b) hereof of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under Section 9(a) or 9(b), notify such indemnifying party in writing of the commencement thereof; but the failure to so notify such indemnifying party shall neither relieve such indemnifying party from any liability that it may have to the indemnified party that failed to give such notice unless and only to the extent that such indemnifying party has been prejudiced by such failure nor relieve it from any liability that it may have to such indemnified party otherwise than under Section 9(a) or 9(b). In case any such action is brought against any such indemnified party and it notifies such indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other indemnifying parties similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of such indemnified party, be counsel to such indemnifying party), and, after notice from such indemnifying party to such indemnified party of its election to so assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under Section 9(a) or 9(b) for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No such indemnifying party shall, without the prior written consent of such indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not such indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of such indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in Section 9(a) or 9(b) hereof is unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) described therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Companies and the Trust on the one hand and the Underwriters on the other from the offering of the Trust Preferred Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if such indemnified party failed to give the notice required under Section 9(c) hereof and such indemnifying party was prejudiced by such failure, then each such indemnified party shall contribute to such amount paid or payable by such indemnified party in

such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Companies and the Trust on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Companies and the Trust on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Trust bear to the total underwriting commission received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Companies or the Trust on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Companies, the Trust and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or any other method of allocation that does not take account of the equitable considerations referred to above in this Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 9(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Trust Preferred Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or allege untrue statement or omission or alleged omission. 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 9(d), each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls any of the Companies or the Trust within the meaning of Section 15 of the Securities Act and each officer or director of such Company or the Trust shall have the same rights to contribution as such Offeror, as the case may be, subject in each case to Sections 9(a) and 9(b) hereof.

Section 10. Survival of Certain Representations and Obligations. Any other provision of this Underwriting Agreement to the contrary notwithstanding, (a) the indemnity and contribution agreements contained in Section 9 hereof, and the representations and warranties and other agreements of the Companies and the Trust contained herein, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or by or on behalf of any of the Companies or the Trust or its directors or officers, or any of the other persons referred to in Section 9 hereof and (ii) acceptance of and payment for the Trust Preferred Securities and (b) the indemnity and contribution agreements contained in Section 9 hereof shall remain operative and in full force and effect regardless of any termination of this Underwriting Agreement.

Section 11. Default of Underwriters. (a) If any Underwriter defaults in its obligation to purchase the number of Trust Preferred Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for such non-defaulting Underwriters or another party or other parties to purchase such number of Trust Preferred Securities on the terms contained herein. If within twenty-four hours after such default by any Underwriter such non-defaulting Underwriters do not arrange for the purchase of such number of Trust Preferred Securities, then the Offerors shall be entitled to a further period of twenty-four hours within which to, but shall not be required to, procure another party or other parties satisfactory to such non-defaulting Underwriters to purchase such Securities on such terms. In the event that, within the respective periods prescribed above, such non-defaulting Underwriters notify the Offerors that they have so arranged for the purchase of such number of Trust Preferred Securities, or the Offerors notify the Underwriters that they have so arranged for the purchase of such number of Trust Preferred Securities, then such non-defaulting Underwriters or the Offerors shall have the right to postpone the Closing Date, for a period of not more than five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Companies and the Trust agree to file promptly any amendments to the Registration Statement or the Prospectus that in the opinion of such non-defaulting Underwriters may thereby be made necessary.

(b) If, after giving effect to any arrangements for the purchase of Trust Preferred Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriter or Underwriters and the Offerors as provided in Section 11(a) hereof, the aggregate number of Trust Preferred Securities that remains unpurchased does not exceed one-eleventh of the aggregate number of all the Trust Preferred Securities to be purchased hereunder, then the Offerors shall have the right to require each non-defaulting Underwriter to purchase the number of Trust Preferred Securities that such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Trust Preferred Securities that such Underwriter agreed to purchase hereunder) of the Trust Preferred Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made, but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Trust Preferred Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriter or Underwriters and the Offerors as provided in Section 11(a) hereof, the aggregate number of Trust Preferred Securities that remains unpurchased exceeds one-eleventh of the aggregate number of all the Trust Preferred Securities to be purchased hereunder, or if the Offerors do not exercise the right provided in Section 11(b) hereof to require such non-defaulting Underwriters to purchase Trust Preferred Securities of a defaulting Underwriter or Underwriters, then this Underwriting Agreement shall thereupon terminate, without liability on the part of any such non-defaulting Underwriter or either of the Offerors, except for the indemnity agreements in Section 9 hereof, but nothing herein shall relieve a defaulting Underwriter from liability for its default.

Section 12. Miscellaneous. THE RIGHTS AND DUTIES OF THE PARTIES TO THIS UNDERWRITING AGREEMENT SHALL, PURSUANT TO NEW YORK GENERAL OBLIGATIONS LAW SECTION 5-1401, BE GOVERNED BY THE LAW OF THE STATE

Nothing herein is intended or shall be construed to give to any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of any provision in this Underwriting Agreement. The term “successor” as used in this Underwriting Agreement shall not include any purchaser, as such purchaser, of any Trust Preferred Securities from the Underwriters.
