| | --- | ---------------------------------------------------------------------------------------------



| | (g) | Delegation by Employer.
| | --- | -----------------------

By authorizing the assets

conferred upon the Sponsor and each employer by the terms of this Agreement, and to take or refrain from taking any and all action which such employer might otherwise take or refrain from taking with respect to this Agreement, including the sole and

no obligation to account to any such employer or to follow the instructions of or otherwise deal with any such Employer, the intention being that the Trustee shall deal solely with the Sponsor.



| | (h) | The Sponsor shall be responsible for verifying that while any assets of a particular Plan are held in the Trust, the Plan (i) is qualified within the meaning
of section 401(a) of the Code; (ii) is permitted by existing or future rulings of the United States

| | Re: | American Savings Bank 401(k) Plan
| | --- | ---------------------------------

Dear Mr. Epstein:

In accordance with your request, we are writing with respect to the qualified status of the American Savings Bank 401(k) Plan (the
Plan) under section 401(a) of the Internal Revenue Code of 1986, as amended, (the Code).

The material facts
regarding the Plan as we understand them are as follows. The Plan is brand new. It was adopted by American Savings Bank, F.S.B. (ASB) on December 30, 2008, effective January 1, 2008. The initial contribution is expected to be a
discretionary, non-elective employer contribution attributable to the Plan year ending December 31, 2008. The initial contribution will be made on or before ASBs tax return deadline for 2008, including extensions thereof. Contributions to
the Plan are conditioned on the Internal Revenue Service making a favorable determination of the tax-qualified status of the Plan. The Plan will be submitted to the Internal Revenue Service for a favorable determination letter on or before
ASBs tax return deadline for 2008. ASB may need to make amendments to the Plan at the request of the Internal Revenue Service in order to obtain a favorable determination letter. We expect ASB to make any amendments reasonably required by the
Internal Revenue Service as part of the determination letter process.

It is expected that assets of the Plan will be invested in the HEI
Common Stock Fund, which is a unitized stock fund that invests primarily in common stock of Hawaiian Electric Industries, Inc., (HEI), a holding company and parent of a controlled group of corporations that includes ASB. The Plan is an
eligible individual account plan (as defined in section

407(d)(3) of the Employee Retirement Income Security Act of 1974, as amended, (ERISA)), and the shares of HEI common stock held in the HEI Common Stock Fund are qualifying employer securities (as defined in section
407(d)(5) of ERISA). We believe that the interests in the Plan will need to be registered under the Securities Act of 1933, as amended, prior to any Plan investments in the HEI Common Stock Fund. We will work with HEIs and ASBs
securities counsel to complete any necessary registration.
