Form of Nonqualified Stock Option Certificate and Statement of Terms and Conditions under the Washington Trust Bancorp, Inc. 2013 Stock Option and Incentive Plan for employees

THIS OPTION is made as of the Grant Date by WASHINGTON TRUST BANCORP, INC. (the “Corporation”) to [NAME] (the “Optionee”).

Pursuant to the Plan and the Statement of Terms and Conditions attached hereto and incorporated herein by reference (the “Statement”), the Corporation hereby awards as of the Grant Date to the Optionee a stock option (the “Option”), as described below, to purchase the Option Shares.

Acceptance of this Option requires no action on the part of the Optionee. However, if the Optionee desires to refuse the Option, he or she must notify the Corporation at the address listed in the attached Statement. This Option is not intended to be an “incentive stock option,” as that term is described in Section 422 of the Internal Revenue Code of 1986, as amended.

This Statement of Terms and Conditions (the “Statement”) supplies the terms and conditions of a grant of a nonqualified stock option (the “Option”) by Washington Trust Bancorp, Inc. (the “Corporation”) under the Washington Trust Bancorp, Inc. 2013 Stock Option and Incentive Plan (the “Plan”). The Option shall be subject to the provisions of the Plan, this Statement and the Certificate.

1.Vesting.

This Option shall become vested and exercisable in accordance with the schedule set forth on the Certificate, provided in each case that the Optionee is then, and since the Grant Date has continuously been, employed by the Corporation or its Subsidiaries. Notwithstanding the Certificate provisions regarding the vesting and exercisability of any option shares in installments, this Option shall become immediately exercisable prior to the vesting date set forth on the Certificate in the following circumstances:

(a)In the event of a Change of Control of the Corporation (as defined in the Plan), any portion of this Option that has not previously been forfeited shall immediately vest; provided that the Optionee is then employed by the Corporation or its Subsidiaries.

(b)In the event of the Optionee’s death, any portion of this Option that has not previously been forfeited shall immediately vest; provided that the Optionee was employed by the Corporation or its Subsidiaries immediately prior to the date of death.

(c)    Upon the Retirement of the Optionee prior to the Vesting Date, the Optionee shall vest in a number of his or her Option shares determined by multiplying the number of Option shares granted to the Optionee by a fraction, the numerator of which shall be the number of full months from the Grant Date to the date of the Optionee’s Retirement and the denominator of which shall be __________. For purposes of this Statement, “Retirement” shall mean the Optionee’s termination of employment with the Company or a Subsidiary after attaining age 65 or after attaining age 55 with at least ten years of service.

2.Termination.

(a)This Option shall terminate and be of no force or effect as of the earliest of the

following:

Notwithstanding the foregoing, in the case of termination for cause, the ability to exercise this Option shall terminate on the date of termination of employment and may be terminated on such earlier date as the Corporation may specify, and such date may be set so as to prevent the Optionee from further exercising any portion of this Option.

Upon the Optionee’s termination of employment, any portion of this Option that is not exercisable at such time shall immediately terminate and be of no force or effect.

(b)The Administrator, as defined in the Plan, shall have discretion to determine whether any termination of the Optionee’s employment by the Corporation is to be considered for cause, or retirement with the consent of the Corporation for the purposes of this Option and this Statement and whether an authorized leave of absence on military or government service or otherwise shall constitute a termination of employment for the purposes of this Option or this Statement. Any determination made by the Administrator with respect to any matter referred to in this Section 2 shall be final and conclusive on all persons affected thereby. Employment by the Corporation shall be deemed to include employment of the Optionee by, and to continue during any period in which the Optionee is in the employment of, a subsidiary of the Corporation.

3.Nontransferability; Persons Able to Exercise. This Option may not be transferred other than by will or the laws of descent and distribution. During the life of the Optionee, only the Optionee may exercise the Option. If the Optionee dies while still affiliated with the Corporation, or during the period specified in Section 2, this Option may be exercised by his executors, administrators, legatees or distributees, provided that such person or persons comply with the provisions of the Certificate, this Statement, and the Plan applicable to the Optionee.

4.Method of Exercising Option. The Option may be exercised, in whole or in part, by written notice to the Chief Human Resources Officer of the Corporation, on any business day prior to the Expiration Date or earlier date specified in Section 2, specifying the number of shares which the Optionee wishes to purchase and including payment of the Option Exercise Price as provided below, provided that the Corporation, in its discretion, may modify or augment these requirements as provided in Section 8 of this Statement, or where appropriate because a person other than the Optionee is exercising the Option pursuant to Section 3. In the event this Option is exercised by any person other than the Optionee, the notice shall be accompanied by appropriate proof of the right of such person to exercise the Option. The written notice specified in this Section must be accompanied by payment of the Option Exercise Price for the shares being purchased in United States dollars in cash or bank check or other instrument acceptable to the Administrator. If approved by the Administrator, in its sole discretion, payment may also be made as follows:

(a)through the delivery (or attestation to the ownership) of shares of Stock, valued at Fair Market Value on the exercise date, that have been purchased by the Optionee on the open market or that are beneficially owned by the Optionee and are not then subject to restrictions under any Corporation plan; or

(b)by the Optionee delivering to the Corporation a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Corporation cash or a check payable and acceptable to the Corporation to pay the purchase price; provided that in the event the Optionee chooses to pay the purchase price as so provided, the Optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure;

(c)by a “net exercise” arrangement pursuant to which the Corporation will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; or

(d)by any combination of the foregoing.

Payment instruments will be received subject to collection. The transfer to the Optionee on the records of the Corporation or of the transfer agent of the Option Shares will be contingent upon (i) the Corporation’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any

other requirements contained in the Certificate, this Statement or in the Plan or in any other agreement or provision of law, and (iii) the receipt by the Corporation of any agreement, statement or other evidence that the Corporation may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of the Option shall be net of the number of shares attested to.

As soon as practical after receipt of this notice and payment and compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with the transfer of shares of Stock upon the exercise of this Option and with the requirements of this Statement, the Certificate and of the Plan, the shares of Stock purchased upon the exercise of this Option shall be transferred to the Optionee on the records of the Corporation or of the transfer agent. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Option unless and until this Option shall have been exercised pursuant to the terms hereof, the Corporation or the transfer agent shall have transferred the shares to the Optionee, and the Optionee’s name shall have been entered as the shareholder of record on the books of the Corporation. Thereupon, the Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. All shares purchased upon the exercise of this Option and payment of the full Option Exercise Price will be fully paid and nonassessable.

This Option shall not be exercised for the purchase of fewer than 50 shares or all shares to which the Option is currently exercisable if such number is less than 50. Notwithstanding any other provision hereof of or the Plan, no portion of this Option shall be exercisable after the Expiration Date hereof.

5.Change of Control. If the Corporation is merged into or consolidated with another corporation under circumstances where the Corporation is not the surviving corporation, or if the Corporation is liquidated or sells or otherwise disposes of all or substantially all of its assets to another corporation while unexercised options remain outstanding under the Plan after the effective date of such merger, consolidation or sale, as the case may be, the Optionee shall be entitled, upon exercise of this Option, to receive in lieu of shares of Stock, shares of such stock or other securities as the holders of shares of Stock received pursuant to the terms of the merger, consolidation or sale.

6.No Rights Other Than Those Expressly Created. Neither this Option, nor the Certificate, nor this Statement, nor the Plan, nor any action taken hereunder shall be construed as (i) giving the Optionee any right to be retained in the employ of, or continue to be affiliated with, the Corporation, (ii) giving the Optionee any equity or interest of any kind in any assets of the Corporation, or (iii) creating a trust of any kind or a fiduciary relationship of any kind between the Optionee and the Corporation. As to any claim for any unpaid amounts under this Option or this Statement, any person having a claim for payments shall be an unsecured creditor. The Optionee shall not have any of the rights of a shareholder with respect to any Option Shares until such time as this Option has been exercised and Option Shares have been issued.

7.Withholding of Taxes. The Optionee shall, not later than the date as of which the exercise of this Option becomes a taxable event for Federal income tax purposes, pay to the Corporation or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. The Corporation shall have the authority to cause the tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Stock to be issued to the Optionee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding amount due.

(a)Amendment. This Option may only be modified or amended by a writing signed by both parties, unless the Administrator determines that the proposed modification or amendment would not

materially and adversely affect the Optionee, in which case the Optionee’s consent shall not be required for such modification or amendment.
