#### 1. Description of the Plan
The following description of the Bank of Hawaii Retirement Savings Plan (the “Plan”) provides only general information about the Plan’s provisions. Participants should refer to the Plan Document for a more complete description of the Plan’s provisions.

#### General
The Plan is a defined contribution plan for employees of Bank of Hawaii Corporation, and certain of its subsidiaries (collectively, the “Company”) who have at least 60 days of service. In addition, the Company provides matching contributions after completion of 12 months of service. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Bank of Hawaii (the “Bank” or the “Plan Administrator”), a subsidiary of the Company, is the Plan administrator and plan sponsor. All assets of the Plan are held in trust by Vanguard Fiduciary Trust Company (“Vanguard”), as trustee, and all benefits are provided by such trust.

Certain prior period information has been reclassified to conform with current year presentation.

#### Contributions
Participating employees are allowed to contribute up to 50% of their eligible compensation (within federal limits) on a pre-tax or after-tax basis to the Plan. The Company makes matching contributions on behalf of participants equal to $1.25 for each $1.00 contributed by participants, up to 2% of the participants’ eligible compensation, and $0.50 for every $1.00 contributed by participants over 2%, up to 5% of the participants’ eligible compensation. A 3% fixed contribution and a discretionary value-sharing contribution, that is linked to the Company’s financial goals, are made regardless of whether the participating employee contributes to the Plan and are invested in accordance with the participant’s selection of investment options available under the Plan
