in connection with the adoption of such child or (ii) for purposes of caring for such child for a period beginning immediately following such birth or placement, the Participant shall not be granted Credited Service for such Period. Such leave
shall not, however, be regarded as a period of severance.

ARTICLE III

ELIGIBILITY

An officer of an Associated Company shall be a Participant only if his
participation in the Plan has been approved by the Compensation Committee of the Board of Directors of the Company. However, in no event may a Participant in this Plan also be eligible to participate in the Hawaiian Electric Industries, Inc. Excess

ARTICLE IV

CONTRIBUTIONS

The Associated Companies shall

ARTICLE

BENEFITS

Section 5.1 Normal
Retirement Income

The monthly amount of retirement income commencing on the Participants Normal Retirement Date on a single life
basis shall be as follows:

(a) (i) The product of the Participants years of Credited Service and 2.04% (but not more than a total of
60%), multiplied by the Participants Final Average Compensation reduced by (ii) (1) the Participants Primary Social Security Benefit in effect at his date or retirement or other termination of service (calculated as if payments
begin at the earliest age at which Social Security Benefits are available), (2) the benefit payable under the Retirement Plan (calculated without regard to the cost of living increases provided for in Section 5.10 of the Retirement Plan)
and (3) the benefit of the Participant derived from employer contributions to any other plan maintained by an Associated Company that qualifies under Section 401(a) of the Code (other than the Hawaiian Electric Industries Retirement
Savings Plan and the Hawaiian Electric Industries, Inc. Stock Ownership Plan). With regard to (ii)(2) and (3) above, the benefits to be offset



4



---

shall be the applicable plans benefit after application of Section 415 of the Code (as it may be amended from
time to time).

(b) Notwithstanding any provision herein to the contrary (including the age requirements of this Plan), a Participant shall
receive as retirement income (as determined on an annual basis, for benefits not paid in a lump sum) at least the amount which would have been paid pursuant to the benefit formula stated in Section 4.2 of the Hawaiian Electric Industries, Inc.
Excess Pay Supplemental Executive Retirement Plan. If benefits are paid in the form of a lump sum, the determination shall include the adjustments described in Section 5.7 and assumed increases in the maximum benefits limitations under
Section 415 of the Internal Revenue Code, in accordance with the applicable actuarial assumptions specified in Appendix I for lump sum distributions.

Section 5.2 Early Retirement Income

(a) If a Participant retires on an Early Retirement Date, his monthly retirement
income commencing on his Early Retirement Date shall be the retirement income payable pursuant to Section 5.1 of this Plan, reduced to reflect the fact that payments shall commence earlier according to the scale in Appendix I interpolated to
the nearest full month; provided, however, that no such reduction may exceed the Actuarial Equivalent reduction permitted to reflect the fact that payment shall commence earlier.

(b) A Participant who has satisfied the Credited Service requirements for an Early Retirement Date, but separated from service with the Participating
Employers and the Associated Companies before satisfying the age requirement for an Early Retirement Income, shall be entitled upon satisfaction of such age requirement to a benefit equal to the benefit to which he would be entitled at his Normal
Retirement Date, actuarially reduced in accordance with Appendix I.

Section 5.3 Postponed Retirement Income

If a Participant remains employed subsequent to his Normal Retirement Date and retires on a Postponed Retirement Date, his retirement income commencing on
his Postponed Retirement Date shall be computed based upon his Credited Service and Compensation (including Credited Service and Compensation credited subsequent to his Normal Retirement Date) as of his Postponed Retirement Date.

Section 5.4 Normal Form of Benefits and Optional Forms

(a) Retirement benefits under this Plan shall begin at the same time and be paid in the same form as the Participants benefit under the Retirement Plan, except that the option for the adjustment for Federal Old Age Benefits (Social
Security) under



5



---

Section 5.8 of the Retirement Plan shall not be applicable. Such benefit shall be the Actuarial Equivalent of the Participants Accrued Benefit,
based on the same actuarial assumptions used in determining optional forms of benefits under the Retirement Plan, as included in Appendix I attached.

(b) Notwithstanding the foregoing, a Participant may at any time within the 90-day period ending one (1) year prior to the annuity starting date make a written election, subject to the approval of the
Compensation Committee of the Board of Directors, to convert his Accrued Benefit into a lump sum payment that is the Actuarial Equivalent of his Accrued Benefit. During such period, his election may be revoked in writing, in which case benefits will
be paid under the same form as benefits under the Retirement Plan, as described in Section 5.4(a).

Section 5.5 Death Benefit for Certain
Participants

(a) If a Participant dies prior to commencement of distribution of his Accrued Benefit, his surviving spouse shall
automatically receive the appropriate survivor benefit provided in the Retirement Plan; provided, however, that if such Participant dies after attainment of his Early Retirement Date, but before actual retirement, his surviving spouse shall receive
a benefit equal to the greater of (i) the appropriate survivor benefit provided in the Retirement Plan or (ii) the survivor annuity described in Section 5.5(b) of this Plan. In the event a survivor annuity
under Section 5.5(b) of this Plan is the greater benefit, the Retirement Plan shall pay so much of that benefit as is permitted under the terms of the Retirement Plan, with the excess being paid from this Plan.

(b) For purposes of this Section 5.5, survivor annuity means a survivor annuity for the life of the surviving spouse of the Participant
under which the payments to the surviving spouse are not less than the amounts that would be payable as a survivor annuity under a Qualified Joint and Survivor Annuity based on the benefit calculated under Section 5.1 of this Plan. In the case
of a Participant who has not attained his Early Retirement Date at the time of death, the survivor annuity shall be calculated as if such Participant had (i) separated from service on his date of death, (ii) survived to his Early
Retirement Date, (iii) retired with an immediate Qualified Joint and Survivor Annuity at his Early Retirement Date and (iv) died on the day after the day on which he would have attained his Early Retirement Date. Such survivor annuity
shall commence to be paid on the first day of the month following the Participants death; provided that, in the case of a Participant who has not attained his Early Retirement Date at the time of death, such survivor annuity shall commence to
be paid as of the date the Participant would have been eligible to receive early retirement income. If the present value of the survivor annuity (as determined by using the interest rate that would be used as of the first day of the Plan Year in
which the



6



---

distribution occurs by the Pension Benefit Guaranty Corporation for purposes of determining the present value of a lump sum distribution on plan termination)
does not exceed $3,500, the Plan shall distribute such value in a lump sum rather than paying such value in the form of an annuity. No such lump sum distribution shall be made (i) if such present value exceeds $3,500 or (ii) after the
commencement of payment of any such annuity.

Section 5.6 Special Distribution Rules

(a) A Participant may request that the distribution of benefits under the Plan commence at a date later than his retirement date. This request must be
made by submitting to the Plan Administrator a written statement, signed by the Participant, that describes the form of distribution and the date on which the Participant requests payment to commence. The Committee shall determine in its sole
discretion whether to grant such request.

(b)    (1) Notwithstanding any other provision of this Plan, if a
change of control (as defined in Section 5.6(b)(2) occurs, then the Actuarial Equivalent of the Accrued Benefit of each retired Participant (or if the retired Participant has died, the portion of his Accrued Benefit to which his
spouse or other beneficiary is entitled) shall be paid in a lump sum to the retired Participant (or if the retired Participant has died, his spouse or other beneficiary) within 30 days of the date of such change in control.

(2) For the purposes of this Section 5.6(b), a change of control shall be deemed
to have taken place if (i) any person, including a group as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, becomes the beneficial owner of shares of the Company having 25% or more of the total number of votes that may
be cast for the election of Directors of the Company; (ii) as the result of, or in connection with, any cash tender or exchange offer, merger, or other business combination, sale of assets, or contested election, or any combination of the
foregoing transactions, the persons who were Directors of the Company before the transaction shall cease to constitute a majority of the Board of Directors of the Company or any successor to the Company; or (iii) a majority of the Board of
Directors of the Company determines in good faith that a change of control is imminent.
