                                VOTING AGREEMENT

         This Voting Agreement (the "AGREEMENT") is made and entered into as of
November 12, 2001, by and among Washington Trust Bancorp., Inc., a Rhode Island
corporation (the "BUYER") and the undersigned stockholder (the "STOCKHOLDER") of
First Financial Corp., a Rhode Island corporation (the "SELLER").

                                    RECITALS

         A. Concurrently with the execution of this Agreement, Buyer and Seller
have entered into an Agreement and Plan of Merger (the "MERGER AGREEMENT"),
which provides for the merger (the "MERGER") of Seller with and into Buyer.
Pursuant to the Merger Agreement, shares of Seller Common Stock (as defined in
the Merger Agreement) will be converted into shares of Buyer Common Stock and
Cash Consideration (each, as defined in the Merger Agreement) on the basis
described in the Merger Agreement.

         B. The Stockholder is the record holder and has either sole or shared
voting power of such number of shares of the outstanding Seller Common Stock, as
is indicated on the final page of this Agreement (the "SHARES").

         C. Buyer desires the Stockholder to agree, and the Stockholder is
willing to agree, not to transfer or otherwise dispose of any of the Shares or
New Shares (as defined in Section 1.2 below, except as otherwise permitted
hereby), and to vote the Shares and New Shares in a manner so as to facilitate
consummation of the Merger, as provided herein.

         NOW, THEREFORE, intending to be legally bound, the parties agree as
follows:

         1.       AGREEMENT TO RETAIN SHARES.

         1.1 TRANSFER AND ENCUMBRANCE. Other than as provided herein, until the
Expiration Date (as defined below), Stockholder shall not hereafter (a) sell,
tender, transfer, pledge, encumber, assign or otherwise dispose of any of the
Shares or New Shares, (b) deposit any Shares or New Shares into a voting trust
or enter into a voting agreement or arrangement with respect to such Shares or
New Shares or grant any proxy or power of attorney with respect thereto, (c)
enter into any contract, option or other arrangement or undertaking with respect
to the direct or indirect sale, transfer, pledge, encumbrance, assignment or
other disposition of any Shares or New Shares, or (d) take any action that would
make any representation or warranty of Stockholder contained herein untrue or
incorrect or have the effect of preventing or disabling Stockholder from
performing Stockholder's obligations under this Agreement; PROVIDED, HOWEVER,
that Stockholder shall be permitted to transfer Shares or any New Shares (i) by
will or by operation of law to the estate of the Stockholder upon the death of
such Stockholder, in which case this Agreement shall be deemed to legally bind
the transferee without any further action on the part of the Buyer, (ii)
pursuant to a pledge agreement, subject to the pledgee agreeing in writing to be
bound by the terms of this Agreement, and (iii) for bona fide estate planning
purposes, subject to the transferee agreeing in writing to be bound by the terms
of this Agreement. As used herein, the term "EXPIRATION DATE" shall mean the
earlier to occur of (i)

                                       1

<Page>

the Effective Time (as defined in the Merger Agreement), and (ii) such date and
time as the Merger Agreement shall be terminated pursuant to Article VIII
thereof.

                  1.2 ADDITIONAL PURCHASES. Stockholder agrees that any shares
of capital stock of Seller that Stockholder purchases or with respect to which
Stockholder otherwise acquires sole or shared voting power after the execution
of this Agreement and prior to the Expiration Date ("NEW SHARES") shall be
subject to the terms and conditions of this Agreement to the same extent as if
they constituted the Shares.

         2. AGREEMENT TO VOTE SHARES. Hereafter until the Expiration Date, at
every meeting of the stockholders of Seller called with respect to any of the
following matters, and at every adjournment or postponement thereof, and on
every action or approval by written consent of the stockholders of Seller with
respect to any of the following matters, Stockholder shall vote the Shares and
any New Shares: (i) in favor of approval of the Merger Agreement and the Merger
and any matter necessary for consummation of the Merger; and (ii) against (x)
approval of any Competing Transaction (as defined in the Merger Agreement) and
(y) any proposal for any action or agreement that is reasonably likely to result
in a breach of any covenant, representation or warranty or any other obligation
or agreement of Seller under the Merger Agreement or which is reasonably likely
to result in any of the conditions of Seller's obligations under the Merger
Agreement not being fulfilled, and (z) any action which could reasonably be
expected to impede, interfere with, delay, postpone or materially adversely
affect consummation of the transactions contemplated by the Merger Agreement.

         3. IRREVOCABLE PROXY. By execution of this Agreement, Stockholder does
hereby appoint and constitute Buyer and the Chief Executive Officer and
President of Buyer, in their respective capacities as officers of Buyer and any
individual who shall hereafter succeed to any such office of Buyer and any other
designee of Buyer, and each of them individually until the Expiration Date, with
full power of substitution and resubstitution, as Stockholder's true and lawful
attorneys-in-fact and irrevocable proxies, to the full extent of the
undersigned's rights with respect to the Shares and any New Shares, to vote each
of such Shares and New Shares solely with respect to the matters set forth in
Section 2 hereof. Stockholder intends this proxy to be irrevocable and coupled
with an interest hereafter until the Expiration Date and hereby revokes any
proxy previously granted by Stockholder with respect to the Shares or New
Shares.

         4. REPRESENTATIONS, WARRANTIES AND COVENANTS OF STOCKHOLDER.
Stockholder hereby represents, warrants and covenants to Buyer as follows:

                  4.1 DUE AUTHORITY. Stockholder has full power, corporate or
otherwise, and authority to execute and deliver this Agreement and to perform
his, her or its obligations hereunder. This Agreement has been duly executed and
delivered by or on behalf of Stockholder and constitutes a legal, valid and
binding obligation of Stockholder, enforceable against Stockholder in accordance
with its terms.

                  4.2 NO CONFLICT; CONSENTS.

                                       2

<Page>

                  (a) The execution and delivery of this Agreement by
Stockholder do not, and the performance by Stockholder of the obligations under
this Agreement and the compliance by Stockholder with any provisions hereof do
not and will not, to the knowledge of the Stockholder, conflict with or violate
any law, statute, rule, regulation, order, writ, judgment or decree applicable
to Stockholder or the Shares or New Shares.

                  (b) The execution and delivery of this Agreement by
Stockholder do not, and the performance of this Agreement by Stockholder will
not, require any consent, approval, authorization or permit of, or filing with
or notification to, any governmental or regulatory authority by Stockholder
except for applicable requirements, if any, of the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"), and except where the failure to obtain
such consents, approvals, authorizations or permits, or to make such filings or
notifications, could not prevent or delay the performance by Stockholder of his,
her or its obligations under this Agreement in any material respect.

                  4.3 OWNERSHIP OF SHARES. Stockholder (i) has either sole or
shared voting power over all of the Shares, which at the date hereof are, and
along with all New Shares at all times up until the Expiration Date will be,
free and clear of any liens, claims, options, charges, proxies or voting
restrictions or other encumbrances, other than any liens, claims, options,
charges, proxies or voting restrictions imposed by this Agreement, and (ii) does
not have either sole or shared voting power over any shares of capital stock of
Seller other than the Shares.

                  4.4 NO SOLICITATIONS. Hereafter until the Expiration Date,
Stockholder shall not, nor, to the extent applicable to Stockholder, shall it
permit any of its affiliates to, nor shall it authorize any partner, officer,
director, employee, advisor or representative of, Stockholder or any of its
affiliates to, (i) solicit proxies or become a "participant" in a "solicitation"
(as such terms are defined in Regulation 14A under the Exchange Act) with
respect to a Competing Transaction, (ii) initiate a stockholders' vote or action
by consent of Seller's stockholders with respect to a Competing Transaction, or
(iii) become a member of a "group" (as such term is used in Section 13(d) of the
Exchange Act) with respect to any voting securities of Seller that takes any
action in support of a Competing Transaction.

         5. NO LIMITATION ON DISCRETION AS DIRECTOR. Notwithstanding anything
herein to the contrary, the covenants and agreements set forth herein shall not
prevent Stockholder or his, her or its representatives or designees who are
serving on the Board of Directors of Seller from exercising his or their duties
and obligations as a Director of Seller or otherwise taking any action, subject
to the applicable provisions of the Merger Agreement, while acting in such
capacity as a director of Seller.

         6. ADDITIONAL DOCUMENTS. Stockholder hereby covenants and agrees to
execute and deliver any additional documents necessary, in the reasonable
opinion of Buyer, to carry out the intent of this Agreement.

         7. TERMINATION. This Agreement shall terminate and shall have no
further force or effect as of the Expiration Date.

Agreement shall nevertheless remain in full force and effect so long as the

affected in any manner materially adverse to any party. Upon such determination

hereto agree that irreparable damage would occur in the event any provision of
this Agreement was not performed in accordance with the terms hereof or was
otherwise breached. It is accordingly agreed that the parties shall be entitled
to specific relief hereunder, including, without limitation, an injunction or
injunctions to prevent and enjoin breaches of the provisions of this Agreement
and to enforce specifically the terms and provisions hereof, in any state or
federal court in the State of Rhode Island, in addition to any other remedy to
which they may be entitled at law or in equity. Any requirements for the
securing or posting of any bond with respect to any such remedy are hereby
waived.

         Re: SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT

Ladies and Gentlemen:

         Reference is hereby made to (i) that certain Agreement and Plan of
Merger (the "MERGER AGREEMENT"), dated as of November 12, 2001, by and between
First Financial Corp., a Rhode Island corporation (the "COMPANY") and Washington
Trust Bancorp, Inc., a Rhode Island corporation (the "BUYER"), pursuant to which
the Buyer will acquire the Company and the Company's banking subsidiary, First
Bank and Trust Company, a Rhode Island commercial bank (the "BANK"), and (ii)
the Second Amended and Restated Employment Agreement, dated as of February 8,
1999, by and among the Company, the Bank and Patrick J. Shanahan, Jr. ("PJS"),
as Chairman, President and Chief Executive Officer of the Company and the Bank
(the "EMPLOYMENT AGREEMENT"). Capitalized terms used in this letter agreement
without definition shall have the meanings given to such terms in the Merger
Agreement or the Employment Agreement, as the case may be.

         As you are aware, Section 9 of the Employment Agreement provides for
the payment of certain compensation and benefits to PJS upon a termination of
his employment following a Change of Control. In connection with the execution
and delivery of the Merger Agreement, the Company, the Bank, PJS and the Buyer
have agreed to the following terms regarding the employment of PJS with the
Company and the Bank:

         1. TERMINATION OF EMPLOYMENT. The employment of PJS with the Company
and the Bank shall terminate on the later to occur of (a) March 1, 2002, if the
Closing occurs on or before February 28, 2002, and (b) the Closing Date. For
purposes of the Employment Agreement, the termination of PJS' employment with
the Company and

<Page>

the Bank pursuant to this Section 1 shall be deemed to occur pursuant to Section
9 of the Employment Agreement.

         2. SECTION 9 OF THE EMPLOYMENT AGREEMENT. Notwithstanding the terms of
Section 9 of the Employment Agreement to the contrary, upon the termination of
PJS' employment with the Company and the Bank in connection with the Merger,
assuming that (a) the payments referred to in Section 5.08 of the Merger
Agreement are made on or prior to December 31, 2001, and (b) the Buyer shall
have executed and delivered the Noncompetition Agreement on or prior to the
Effective Time, PJS shall no longer be entitled to any of the compensation or
benefits described in Section 9 of the Employment Agreement and in lieu of such
compensation and benefits, the Buyer shall provide or cause to be provided to
PJS, and PJS shall be entitled to receive, from and after the Effective Time,
each of the benefits described in EXHIBITS A AND B to this letter agreement
(other than those benefits already paid to PJS prior to the Effective Time);
PROVIDED, HOWEVER, that the aggregate present value of the non-cash benefits set
forth on EXHIBIT A shall be limited to $165,000.00 (subject to adjustment by
mutual agreement following the receipt of PJS's final 2001 W-2 in order to avoid
the imposition of an excise tax under Section 280G of the Code (as defined
below)) (the "MAXIMUM AMOUNT") and to the extent the aggregate present value of
such benefits exceeds the Maximum Amount, the benefits will be reduced or
adjusted in the manner requested by PJS. If either of (a) or (b) above does not
occur on or prior to the dates set forth above, this Section 2 shall be null and
void and PJS shall be entitled to receive the compensation and other benefits
provided under Section 9 of the Employment Agreement upon the termination of his
employment, subject to the terms thereof.

         3.       280G OF THE CODE.

                  (a) Each of the parties does not intend or expect that the
         arrangements described in (i) Section 5.08 of the Merger Agreement,
         (ii) the Noncompetition Agreement, (iii) this letter agreement, and
         (iv) any other payment or benefit to which PJS shall be entitled, will
         result in any "excess parachute payments" within the meaning of Section
         280G of the Internal Revenue Code of 1986, as amended (the "CODE"). The
         parties hereto further acknowledge that EXHIBIT B to this letter
         agreement sets forth the only compensation, payments or distributions
         to or for the benefit of PJS, which PJS is or may be entitled to
         receive following the date hereof (whether or not such payments are in
         connection with the Merger) by the Company, the Bank, the Buyer or any
         affiliate of Buyer in connection with his employment with the Company
         and the Bank prior to the Closing Date or the termination thereof. The
         Company has provided Buyer with true and correct copies of Forms W-2
         relating to PJS's compensation for each of the years ended December 31,
         1997 through 2000 and represent that, to its knowledge, Box 1 on the
         Form W-2 relating to PJS's compensation for the year ending December
         31, 2001 will be $443,088.53 (excluding the payment of the Special
         Bonus contemplated in Section 5.08 of the Merger

                                       2

         Agreement). PJS agrees to deliver a certificate (the "CLOSING
         CERTIFICATE") to Buyer dated the date of the closing date of the
         Merger, in which PJS will certify that he has not received, is not
         entitled to receive and has not entered into any agreement, arrangement
         or understanding pursuant to which he may be entitled to receive, any
         compensation, payment or distribution from the Company, the Bank, the
         Buyer or any affiliate of Buyer in connection with his employment with
         the Company and the Bank prior to the Closing Date or the termination
         thereof, other than as specified on EXHIBIT B, it being understood that
         EXHIBIT B shall not include any compensation or benefits to which PJS
         shall be entitled as a director of the Company, the Bank, Buyer and the
         Buyer Bank from and after the Closing Date ("DIRECTOR COMPENSATION").
         Buyer acknowledges and agrees that PJS will have no liability to the
         Buyer, the Company, the Bank or any affiliate of any of the foregoing
         in connection with the execution and delivery of the Closing
         Certificate; PROVIDED, HOWEVER, that the foregoing notwithstanding, no
         party hereto shall be relieved of any liability as a result of such
         party's gross negligence or willful misconduct.

                  (b) Subject to Section 3(c) hereof, in the event that it shall
         be determined by the Internal Revenue Service that any compensation,
         payment or distribution by the Seller, Bank, Buyer of any affiliate of
         the Buyer to or for the benefit of PJS (including, without limitation,
         entitlements subject to a contingency), whether paid or payable or
         distributed or distributable pursuant to the terms of this letter
         agreement or otherwise (the "SEVERANCE PAYMENTS"), would be subject to
         the excise tax imposed by Section 4999 of the Code, or any interest or
         penalties are incurred by PJS with respect to such excise tax (such
         excise tax, together with any such interest and penalties, are
         hereinafter collectively referred to as the "EXCISE TAX"), then PJS
         shall be entitled to receive an additional payment from the Company (or
         its successor) (a "GROSS-UP PAYMENT") such that the net amount retained
         by PJS, after deduction of any Excise Tax on the Severance Payments and
         Excise Tax (and federal, state and local income taxes and employment
         taxes) upon the payment provided by this subsection (applying maximum
         marginal rates of tax), but not after the deduction of any other taxes
         or amounts, shall be equal to the Severance Payments. (The Gross-Up
         Payment is not intended to compensate PJS for any income taxes payable
         with respect to the Severance Payments.)

                  (c) Notwithstanding anything in this letter agreement to the
         contrary, if it is determined that PJS has received or is entitled to
         receive (including, without limitation, entitlements subject to a
         contingency) any compensation, payments or distributions from Seller,
         Bank, Buyer or any affiliate of Buyer other than as specified on
         EXHIBIT B (including, without limitation, compensation, payments or
         distributions which may be

                                       3

<Page>

         contemplated on EXHIBIT B but which are effected other than as
         specified on EXHIBIT B) and other than Director Compensation, Buyer
         shall so notify PJS and PJS shall be entitled to notify Buyer within
         ten days that he elects to forego the receipt of such compensation,
         payment or distribution, in which case, the remaining provisions of
         this Section 3(c) shall not be applicable. If PJS does not deliver any
         such notice to Buyer within such time frame, PJS shall be deemed to
         have elected to forego the receipt of such compensation, payment or
         distribution, in which case, the remaining provisions of this Section
         3(c) shall not be applicable. If PJS notifies Buyer that he does not
         elect to forego the receipt of such compensation, payment or
         distribution, then Section 3(b) hereof shall be void and of no force
         and effect and the compensation, payments and distributions paid,
         payable, distributed or distributable to PJS pursuant to EXHIBIT B or
         otherwise shall be reduced (but not below zero) to the extent necessary
         so that the maximum amount of compensation, payments and distributions
         to which PJS is or may be entitled shall not exceed the Threshold
         Amount (as defined below). To the extent that there is more than one
         method of reducing the payments to bring them within the Threshold
         Amount, PJS shall determine which method shall be followed; provided
         that if PJS fails to make such determination within 10 days after the
         Buyer has sent PJS written notice of the need for such reduction, the
         Buyer may determine the amount of such reduction in its sole
         discretion. For the purposes of this Section 3(c), "THRESHOLD AMOUNT"
         shall mean three times PJS's "base amount" within the meaning of
         Section 280G(b)(3) of the Code and the regulations promulgated
         thereunder less one dollar ($1.00).

                  (d) The determination of the Excise Tax, the Gross-Up Amount
         and the Threshold Amount under this Section 3 shall initially be made
         by KPMG LLP, which shall provide detailed supporting calculations both
         to the Buyer and PJS upon the determination of any such amounts. PJS
         shall have ten days from the date of delivery to provide notice to
         Buyer that he disputes such calculations, in which case, Buyer and PJS
         shall cooperate in good faith to resolve such dispute as soon as
         possible thereafter and, in any event, within ten days after PJS
         notifies the Buyer of the disputed items. If, after such ten day
         period, no agreement of the parties is reached, such dispute shall be
         resolved by a nationally recognized accounting firm (other than KPMG
         LLP, Arthur Andersen LLP or any other accounting firm that provides
         services to the Buyer) selected by the Buyer and reasonably acceptable
         to PJS (the "Accounting Firm"). The parties shall use their best
         efforts to cause the Accounting Firm to resolve such dispute within ten
         days after the parties engage such Accounting Firm and, in connection
         therewith, shall provide the Accounting Firm with all documentation
         reasonably necessary for the Accounting Firm to resolve such dispute
         within such time period. Any determination by the Accounting Firm shall
         be binding upon

                                       4

         the Buyer and PJS. The costs and expenses of the Accounting Firm shall
         be borne by Buyer.

         This letter agreement shall terminate and the terms hereof shall be of
no force and effect if the Merger Agreement shall be terminated and, following
such termination, Buyer shall have no liability or obligation for any payments,
compensation or distributions contemplated hereunder.

         Except as expressly set forth herein, all terms and conditions of the
Employment Agreement shall remain in full force and effect.
