Pursuant to the Washington Trust Bancorp, Inc. 2013 Stock Option and Incentive Plan (the “Plan”) as amended through the date hereof, Washington Trust Bancorp, Inc. (the “Corporation”) hereby grants a Restricted Stock Award (an “Award”) to the Grantee named above. Upon acceptance of this Award, the Grantee shall receive the number of shares of common stock, par value U.S. $0.0625 per share (the “Stock”) of the Corporation specified above, subject to the restrictions and conditions set forth herein and in the Plan. Any consideration due to the Corporation with respect to the par value of the Stock will be satisfied in the form of cash or by past or future services rendered to the Corporation by the Grantee or such other form of consideration as is acceptable to the Administrator.

1.Acceptance of Award. The Grantee shall have no rights with respect to this Award unless he or she shall have accepted this Award by signing and delivering to the Corporation a copy of this Award Agreement. Upon acceptance of this Award by the Grantee, the shares of Restricted Stock so accepted shall be issued and held by the Corporation’s transfer agent in book entry form or issued in the form of stock certificates, as determined by the Corporation, and the Grantee’s name shall be entered as the shareholder of record on the books of the Corporation. Thereupon, the Grantee shall have all the rights of a shareholder with respect to such shares, including voting and dividend rights, subject, however, to the restrictions and conditions specified herein.

2.Restrictions and Conditions.

(a)Shares of Restricted Stock granted herein may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of by the Grantee prior to vesting.

(b)In the event the Grantee ceases to be an active member of the Board for any reason other than those provided in Section 3 of this Statement prior to the applicable Vesting Date, all shares of Restricted Stock that have not vested shall be immediately and automatically be forfeited and returned to the Corporation.

3.Vesting of Restricted Stock. The restrictions and conditions in Paragraph 2 of this Agreement shall lapse on the Vesting Date or Dates specified in the following schedule so long as the Grantee remains an active member of the Board on such Dates. If a series of Vesting Dates is specified, then the restrictions and conditions in Section 2 shall lapse only with respect to the number of shares of Restricted Stock specified as vested on such date.

Subsequent to such Vesting Date or Dates, the shares of Stock on which all restrictions and conditions have lapsed shall no longer be deemed Restricted Stock. The Administrator may at any time accelerate the vesting schedule specified in this Section 3.

Notwithstanding the foregoing, the Grantee shall become vested in the shares of Restricted Stock prior to the Vesting Dates in the following circumstances:

(a)In the event of a Change of Control of the Corporation (as defined in the Plan), all shares of Restricted Stock that have not previously been forfeited shall immediately vest; provided that the Grantee is then an active member of the Board.

(b)In the event of the Grantee’s death, all shares of Restricted Stock that have not previously been forfeited shall immediately vest; provided that the Grantee was an active member of the Board immediately prior to the date of death.

(c)Upon the Retirement of the Grantee prior to the final Vesting Date, all shares of Restricted Stock that have not been previously forfeited shall immediately vest.

For purposes hereof, “Retirement” shall mean the Grantee’s cessation of service as a Director as of the Annual Meeting date following the attainment of age 70.

4.Certificates.

(a)Legended Certificates. The Grantee is executing and delivering to the Corporation blank stock powers to be used in the event of forfeiture. Any certificates representing shares of unvested Restricted Stock shall be held by the Corporation and such certificates (and, to the extent determined by the Corporation, any other evidence of ownership of unvested Restricted Stock) shall contain the following legend:

THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) OF THE ISSUER’S 2013 STOCK OPTION AND INCENTIVE PLAN AND A RESTRICTED STOCK AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER AND THE ISSUER. COPIES OF SUCH PLAN AND AGREEMENT ARE ON FILE IN THE OFFICES OF THE ISSUER.

(b)Book Entry. Any book entries for the shares of Restricted Stock granted herein shall bear an appropriate legend, as determined by the Administrator in its sole discretion, to the effect that such shares are subject to restrictions as set forth herein and in the Plan. If unvested shares of Restricted Stock are held in book entry form, the Grantee agrees that the Corporation may give stop transfer instructions to the transfer agent to ensure compliance with the provisions of this Agreement.

(c)Acknowledgement. The Grantee hereby (i) acknowledges that the Restricted Stock may be held in the book entry form on the books of the Corporation’s transfer agent and irrevocably authorizes the Corporation to take such actions as may be necessary or appropriate to effectuate a transfer of the record ownership of any such shares that are unvested and forfeited hereunder; (ii) agrees to deliver to the Corporation, as a precondition to the issuance of any certificate or certificates with respect to unvested shares of Restricted Stock, one or more stock powers, endorsed in blank, with respect to such shares; and (iii) agrees to sign other powers and take such other action as the Corporation may reasonably request to accomplish the transfer or forfeiture of any shares of unvested Restricted Stock that are forfeited hereunder.

8.Amendment. This Agreement 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 Grantee, in which case the Grantee’s consent shall not be required for such modification or amendment.
