          This statement is filed on behalf of CFX Corporation ("CFX").  CFX is
a New Hampshire corporation with its principal executive offices at 102 Main
Street, Keene, New Hampshire 03431.  CFX is a bank holding company registered

engaged in the business of managing and controlling banks and activities closely
related to banking.

          Filed as Schedule I to this Schedule 13D is a list of the executive

to each such person:  (a) name, (b) business address and (c) present principal

competent jurisdiction and as a result was or is subject to a judgment, decree

Item 3.   Source and Amount of Funds or Other Consideration.
- ------    -------------------------------------------------

          Pursuant to a Stock Option Agreement dated as of January 5, 1996
("Option Agreement"), Safety Fund has granted to CFX an option ("Option") to
purchase up to 332,000 shares of common stock, par value $5.00 per share, of
Safety Fund ("Safety Fund Common Stock"), subject to adjustment as provided in
the Option Agreement.  The exercise price under the Option Agreement is $20.00
per share and the aggregate amount of funds required to exercise the Option in
full would be $6,640,000.  [If and when the Option is exercised, CFX's source of
funds will be either working capital or funds borrowed from one or more banks in
the ordinary course of business; the identity of such bank or banks has not yet
been determined.]

Item 4.   Purpose of Transaction.
- ------    ----------------------

          On January 5, 1996, CFX and Safety Fund entered into an Agreement and
Plan of Merger ("Merger Agreement") that provides for the merger of a wholly
owned subsidiary of CFX to be formed under Massachusetts law with and into
Safety Fund followed by the merger of the surviving corporation with and into
CFX ("Merger") and the conversion of each outstanding share of Safety Fund
Common Stock (except as provided in the Merger Agreement) into a specified
number of shares of common stock of CFX (based on an exchange ratio to be
determined in accordance with the Merger Agreement), and cash in lieu of certain
fractional shares.  The Merger Agreement also contemplates the possible merger
of certain subsidiaries of Safety Fund and CFX after the consummation of the
Merger.

          CFX and Safety Fund have entered into the Option Agreement in order to
facilitate the consummation of the Merger and other transactions contemplated by
the Merger Agreement.  Consummation of the Merger is subject to, among other
things, receipt of all necessary shareholder and government approvals.

          CFX has no present intention to acquire any shares of Safety Fund
Common Stock except pursuant to the Merger Agreement and the Option Agreement.

          Except as otherwise set forth in Items 4, 5 and 6 hereof and the
Exhibits to this Schedule 13D (which are hereby incorporated by reference herein
and made a part hereof to the same extent as though set forth herein in full),
CFX does not now have any plans or proposals which relate to or would result in
(i) the acquisition by any person of additional securities of Safety Fund, or
the disposition of securities of Safety Fund; (ii) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving Safety
Fund or any of its subsidiaries; (iii) any change in the present Board of
Directors or management of Safety Fund, including any change in the number or
term of Safety Fund directors or the filling of any existing vacancies on the
Board of Directors of Safety Fund; (iv) any material change in the present
capitalization or dividend policy of Safety Fund; (v) any other material change
in the business or corporate structure of Safety Fund; (vi) changes in Safety
Fund's charter, bylaws or instruments corresponding thereto or other actions
which may impede the acquisition of control of Safety Fund by any person;
(vii) causing a class of securities of Safety Fund to be delisted from a
national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association;
or (viii) a class of equity securities of Safety Fund becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Securities
Exchange Act of 1934.


Item 5.  Interest in Securities of the Issuer.
- ------   ------------------------------------
          The 332,000 shares of Safety Fund Common Stock subject to the Option
represent approximately 16.7% of the 1,992,665 shares of Safety Fund Common
Stock that would be issued and outstanding upon exercise of the Option in full.
 Unless and until the Option is exercised, CFX disclaims beneficial ownership of
the Safety Fund Common Stock subject to the Option.

          Except as otherwise described herein, neither CFX, nor, to the best of
CFX's knowledge, any of the persons listed on Schedule I hereto, beneficially
owns any shares of Safety Fund Common Stock.  Other than as described in this
Schedule 13D, no transactions in Safety Fund Common Stock were effected during
the past 60 days by CFX, or, to the best of CFX's knowledge, by any of the
persons listed on Schedule I hereto.

Item 6.   Contracts, Arrangements, Understandings or Relationships with Respect
- ------    ---------------------------------------------------------------------
          to Securities of the Issuer.
          ---------------------------


Option Agreement
- ----------------

          Set forth below is a description of selected provisions of the Option
Agreement.  Such description is qualified in its entirety by reference to the
copy of the Option Agreement filed as an Exhibit hereto, which is incorporated
herein by reference and made a part hereof to the same extent as though set
forth herein in full.

          Under the Option Agreement, Safety Fund granted CFX the right to
purchase up to 332,000 shares of Safety Fund Common Stock at a purchase price of
$20.00 per share.  The Option Agreement was executed to facilitate the Merger.
CFX may exercise the Option upon the occurrence of any of the following events
(each a "Purchase Event") after the execution of the Option Agreement:

          (a)  any person (other than Safety Fund, any Safety Fund subsidiary,
CFX, or any CFX affiliate) shall have commenced a bona fide tender or exchange
offer to purchase shares of Safety Fund Common Stock such that, upon
consummation of such offer, such person would own or control 10% or more of the
outstanding shares of Safety Fund Common Stock;

          (b)  any person (other than Safety Fund or any Safety Fund
subsidiary), other than in connection with a transaction to which CFX has given
its prior written consent, shall have filed an application or notice with any
federal or state regulatory agency for clearance or approval, to (i) merge or
consolidate, or enter into any similar transaction, with Safety Fund or any
Safety Fund subsidiary, (ii) purchase, lease or otherwise acquire all or
substantially all the assets of Safety Fund or any Safety Fund subsidiary, or
(iii) purchase or otherwise acquire (including by way of merger, consolidation,
share exchange or any similar transaction) securities representing 10% or more
of the voting power of Safety Fund or any Safety Fund subsidiary;

          (c)  any person (other than Safety Fund, any Safety Fund subsidiary,
subsidiaries of Safety Fund in a fiduciary capacity, CFX, affiliates of CFX, or
subsidiaries of CFX in a fiduciary capacity) shall have acquired beneficial
ownership or the right to acquire beneficial ownership of 10% or more of the
outstanding shares of Safety Fund Common Stock (the term "beneficial ownership"
for purposes of the Option Agreement having the meaning assigned thereto in
Section 13(d) of the Securities Exchange Act of 1934 and the regulations
promulgated thereunder);

          (d)  any person (other than Safety Fund or any Safety Fund subsidiary)
shall have made a bona fide proposal to Safety Fund by public announcement or
written communication that is or becomes the subject of public disclosure to
(i) acquire Safety Fund or any Safety Fund subsidiary by merger, consolidation,
purchase of all or substantially all its assets or any other similar
transaction, or (ii) make an offer described in clause (a) above; or

          (e)  Safety Fund shall have willfully breached any covenant contained
in the Merger Agreement, which breach would entitle CFX to terminate the Merger
Agreement (without regard to the cure periods provided for therein) and such
breach shall not have been cured in accordance with the Option Agreement.

          The Option may be exercised in whole or in part, at one or more
closings, and may be exercised at any time if a Purchase Event shall have
occurred and be continuing after the date of the Option Agreement and before the
Option Agreement is terminated.  The Option Agreement provides that, to the
extent that it shall have not been exercised, the Option shall terminate on the
earliest of:

          (a)  the effective date of the Merger;

          (b)  the termination of the Merger Agreement in accordance with the
provisions thereof prior to the occurrence of a Purchase Event (other than a
termination resulting from a willful breach by Safety Fund of any covenants
contained therein); or

          (c)  six months after termination of the Merger Agreement if such
termination follows the occurrence of a Purchase Event or is due to a willful
breach by Safety Fund of any covenant contained therein.

          In the event of any change in Safety Fund Common Stock by reason of
stock dividends, split-ups, mergers, recapitalizations, combinations, exchanges
of shares or the like, the type and number of shares subject to the Option, and
the purchase price therefor, shall be adjusted appropriately.  Also, in the
event that any additional shares of Safety Fund Common Stock are issued or
otherwise become outstanding after the date of the Option Agreement (other than
pursuant to the Option Agreement), the number of shares of Safety Fund Common
Stock subject to the Option shall be adjusted so that, after such issuance, it
equals 19.9% of the number of shares of Safety Fund Common Stock then issued and
outstanding without giving effect to any shares subject or issued pursuant to
the Option.  In the event Safety Fund issues or agrees to issue any shares of
Safety Fund Common Stock in breach of its obligations under the Merger Agreement
at a price less than $20.00 per share (as adjusted pursuant to the Option
Agreement), the exercise price on the Option shall be equal to such lesser
price.

          The Option Agreement also provides that Safety Fund will repurchase
the Option (whether or not previously terminated) from CFX, together with any
shares of Safety Fund Common Stock purchased by CFX pursuant to the Option, at
the request of CFX at any time commencing upon the occurrence of one of the
following events and ending nine months thereafter:

          (a)  any person (other than Safety Fund, any Safety Fund subsidiary,
CFX, or any CFX affiliate) shall have acquired beneficial ownership of 51% or
more of the outstanding shares of Safety Fund Common Stock; or

          (b)  any person (other than CFX or any CFX affiliate) shall have
entered into an agreement, arrangement or understanding (whether or not in
writing) with Safety Fund or any Safety Fund subsidiary to (i) merge or
consolidate, or enter into any similar transaction, with Safety Fund or any
Safety Fund subsidiary, (ii) purchase, lease or otherwise acquire all or
substantially all the assets of Safety Fund or any Safety Fund subsidiary, or
(iii) purchase or otherwise acquire (including by way of merger, consolidation,
share exchange or any similar transaction) securities representing 51% or more
of the voting power of Safety Fund or any Safety Fund subsidiary.

          The repurchase price shall be equal to the sum of:

          (a)  the exercise price paid by CFX for any shares of Safety Fund
Common Stock acquired pursuant to the Option;

          (b)  the difference between the "market/tender offer" price for shares
of Safety Fund Common Stock (defined as the higher of the highest price per
share at which a tender or exchange offer has been made or the highest reported
sale price for shares of Safety Fund Common Stock within that portion of the
Repurchase Period preceding the date CFX gives notice of the required
repurchase) and the exercise price as determined pursuant to the Option
Agreement multiplied by the number of shares of Safety Fund Common Stock with
respect to which the Option has not been exercised, but only if the
market/tender offer price is greater than such exercise price;

          (c)  the difference between the market/tender offer price and the
exercise price paid by CFX for any shares of Safety Fund Common Stock purchased
pursuant to the exercise of the Option, multiplied by the number of shares so
purchased, but only if the market/tender offer price is greater than such
exercise price; and

          (d)  CFX's out-of-pocket expenses incurred in connection with the
transactions contemplated by the Merger Agreement, including, without
limitation, legal, accounting and investment banking fees.


Merger Agreement
- ----------------


          Set forth below is a description of selected provisions of the Merger
Agreement.  Such description is qualified in its entirety by reference to the
copy of the Merger Agreement filed as an Exhibit hereto, which is incorporated
herein by reference and made a part hereof to the same extent as though set
forth herein in full.

          The Merger Agreement provides that, on the effective date of the
Merger, a wholly owned subsidiary of CFX to be formed under Massachusetts law
will be merged with and into Safety Fund followed by the merger of the surviving
corporation with and into CFX and the conversion of each outstanding share of
Safety Fund Common Stock (except as provided in the Merger Agreement and
including any rights attached thereto) into a specified number of shares of
common stock of CFX (based on an exchange ratio to be determined in accordance
with the Merger Agreement), and cash in lieu of certain fractional shares.

          The Merger Agreement also provides that, from the date of the Merger
Agreement until the effective date of the Merger, except with the written
consent of CFX, Safety Fund will operate its business, and will cause each of
its subsidiaries to operate its business, only in the usual regular and ordinary
course of business, will use reasonable efforts to preserve intact its business
organization and assets and maintain its rights and franchises, and will take no
action which would materially adversely affect the ability of CFX or Safety Fund
to obtain necessary approvals of governmental authorities required for the
transactions contemplated by the Merger Agreement or materially increase the
period of time necessary to obtain such approvals, or materially adversely
affect Safety Fund's ability to perform its covenants and agreements under the
Merger Agreement.

          During such period, Safety Fund also agreed, among other things, that,
except as otherwise specifically permitted or required by the Merger Agreement
or consented to by CFX, Safety Fund will not and will cause each of its
subsidiaries not to:

          (a)  Change or waive any provision of its charter documents.

          (b)  Change the number of shares of its authorized or issued capital
stock except as may be required by the Option Agreement or as contemplated in
connection with Safety Fund's Shareholder Rights Plan ("Shareholder Rights
Plan").

          (c)  Issue or grant any option, warrant, call, commitment,
subscription, right to purchase or agreement of any character relating to the
authorized or issued capital stock of Safety Fund or any of its subsidiaries, or
any security convertible into shares of such stock, except as contemplated by
the Shareholders Rights Plan, the Option Agreement or any Safety Fund employee
stock option plan.

          (d)  Effect any recapitalization, reclassification, stock dividend,
stock split or like change in capitalization, or redeem repurchase or otherwise
acquire any shares of Safety Fund Common Stock except pursuant to any
Shareholder Rights Plan.

          (e)  Declare or pay any dividends or other distributions with respect
to its capital stock except for (i) dividends and distributions paid pursuant to
the Shareholder Rights Plan, (ii) dividends or distributions paid by any Safety
Fund Subsidiary to Safety Fund, and (iii) specified quarterly cash dividends
with respect to Safety Fund Common Stock declared and paid by Safety Fund in
accordance with applicable law, regulation and contractual and regulatory
commitments.

          (f)  Enter into, amend in any material respect or terminate any
contract or agreement that is or may reasonably be expected to have a material
adverse effect on Safety Fund and its subsidiaries, taken as a whole, except in
the ordinary course of business consistent with past practice.

          (g)  Incur any material liabilities or material obligations or acquire
any equity, debt, or other investment securities except in the ordinary course
of business consistent with past practice.

          (h)  Make any capital expenditures other than in the ordinary course
of business or as necessary to maintain existing assets in good repair.

          (i)  Merge into, consolidate with, affiliate with, or be purchased or
acquired by, any other person, or permit any other person to be merged,
consolidated or affiliated with Safety Fund.

          (j) Take or cause any action to be taken which would disqualify the
Merger as a "pooling of interests for accounting purposes or a tax free
reorganization under the Internal Revenue Code of 1986, as amended.

          Safety Fund also agreed not to authorize or permit any of its
officers, directors, employees or agents to directly or indirectly solicit,
initiate or encourage any inquiries relating to, or the making of any proposal
which constitutes, any tender or exchange offer, proposal for a merger,
consolidation or other business combination involving Safety Fund or any if its
subsidiaries or any proposal or offer to acquire in any manner a substantial
portion of the assets of Safety Fund or any of its subsidiaries, other than as
contemplated or permitted by the Merger Agreement or the Option Agreement.
Safety Fund also agreed not to recommend or endorse any such proposal (except to
the extent legally required for the discharge of the fiduciary duties of Safety
Fund's Board of Directors) or participate in any discussions or negotiations or
provide third parties with any non-public information relating to any such
inquiry or proposal.

          Both CFX and Safety Fund have agreed to use all reasonable efforts to
obtain as soon as practicable all consents and approvals of any persons
necessary or desirable for the consummation of the Merger and other transactions
contemplated by the Merger Agreement, including the approval of the respective
shareholders of CFX and Safety Fund and all consents and approvals required of
applicable federal and state regulatory authorities.

          Reference is made to Item 4 hereof for a description of certain other
provisions of the Merger Agreements.


Additional Agreements
- ---------------------

          In connection with the Merger, each member of the Board of Directors
of Safety Fund, each in his or her capacity as a shareholder of such company,
has agreed with CFX to vote or cause to be voted for approval of the Merger
Agreement all of his or her shares which he or she is entitled to vote with
respect thereto.  In addition, each of such persons has agreed not to transfer
or otherwise dispose of his or her shares of Safety Fund Common Stock or to
pledge or otherwise encumber any additional shares prior to shareholder approval
of the Merger Agreement or termination of the Merger Agreement pursuant to the
terms thereof.  Each such person has also agreed not to take any action that
would substantially impair the prospects of completing the Merger pursuant to
the Merger Agreements.

and outstanding immediately prior to the Effective Time (other than Dissenting
Shares (as such term is defined in Section 2.10 hereof) and other than Safety
Fund Common Stock then owned by Safety Fund, any Safety Fund Subsidiary, Buyer,
or any Buyer Subsidiary (in each case other than in a fiduciary capacity or in
connection with debts previously contracted)), including each attached right 
issued pursuant to the Shareholder Rights Plan (as hereinafter defined), shall,
by virtue of the Merger and without any action on the part of the holder
thereof, be converted into and exchangeable for an amount of common stock, par

number of shares of Buyer Common Stock, rounded down to the nearest whole share,
determined by multiplying the number of shares of Safety Fund Common Stock held
of record and beneficially by such Holder as of the Closing by the difference
between the Pooling Exchange Ratio and the Purchase Exchange Ratio.  A
Triggering Event shall have occurred if, on or before the date which is three
months after the Closing Date, a Pooling Determination is made with respect to
the Merger.  During the three-month period following the Effective Date, Buyer
shall regularly cause an inquiry to be made as to whether a Pooling
Determination can be made and shall cause a Pooling Determination to be made as
promptly as practicable after the occurrence of events that would permit such a
determination to be made based on facts not determinable prior to the Effective

to mail to each Record Holder of a Certificate or Certificates, a form letter of
transmittal for return to the Exchange Agent and instructions for use in
effecting the surrender of the Certificates for certificates representing the
Buyer Common Stock and the cash in lieu of fractional shares into which the
Safety Fund Common Stock represented by such Certificates shall have been
converted as a result of the Merger.  The form letter (which shall be subject to
the reasonable approval of Safety Fund) shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
delivery of the Certificates to the Exchange Agent.  Upon surrender of a
Certificate for exchange and cancellation to the Exchange Agent, together with
such letter of transmittal, duly executed, the holder of such Certificate shall

<PAGE>
 
such holder has the right to receive in respect of Certificates surrendered
pursuant to the provisions of this Section 2.8, and the Certificates so
surrendered shall forthwith be cancelled.  In the event any Certificate shall

fact by the person claiming such Certificate to be lost, stolen or destroyed
and, if required by Buyer, the posting by such person of a bond in such amount
as Buyer may direct as indemnity against any claim that may be made against it

such lost, stolen or destroyed Certificate the Merger Consideration deliverable

an "affiliate" of Safety Fund for purposes of Rule 145(c) under the Securities
Act of 1933, as amended (the "Securities Act") shall not be exchanged for

the written agreement of such person contemplated by Section 7.3 hereof.

          (c)  RIGHTS OF CERTIFICATE HOLDERS AFTER THE EFFECTIVE TIME.  The
holder of a Certificate that prior to the Merger represented issued and
outstanding Safety Fund Common Stock shall have no rights, after the Effective
Time, with respect to such Safety Fund Common Stock except to surrender the
Certificate in exchange for the Merger Consideration as provided in this
Agreement or to perfect the rights of appraisal as a holder of Dissenting Shares
that such holder may have pursuant to the applicable provisions of Massachusetts
law. No dividends or other distributions declared after the Effective Time with
respect to Buyer Common Stock shall be paid to the holder of any un-surrendered
Certificate until the holder thereof shall surrender such Certificate in
accordance with this Section 2.8. After the surrender of a Certificate in
accordance with this Section 2.8, the record holder thereof shall be entitled to
receive any such dividends or other distributions, without any interest thereon,
which theretofore had become payable with respect to shares of Buyer Common
Stock represented by such Certificate.

          (d)  FRACTIONAL SHARES.  Notwithstanding anything to the contrary
contained herein, no certificates or scrip representing fractional shares of
Buyer Common Stock shall be issued upon the surrender for exchange of
Certificates, no dividend or distribution with respect to Buyer Common Stock
shall be payable on or with respect to any fractional share, and such fractional
share interests shall not entitle the owner thereof to vote or to any other
rights of a stockholder of Buyer.  In lieu of the issuance of any such
fractional share, Buyer shall pay to each former holder of Safety Fund Common
Stock who otherwise would be entitled to receive a fractional share of Buyer
Common Stock, an amount in cash determined by multiplying the closing sale price
of Buyer Common Stock on the Stock Exchange as reported by The Wall Street
Journal for the trading day immediately preceding the date of the Effective Time
(the "Last Closing Price") by the fraction of a share of Buyer Common Stock
      ------------------

hereof.  No interest will be paid on the cash which the holders of such
fractional shares shall be entitled to receive upon such delivery.

          (e)  SURRENDER BY PERSONS OTHER THAN RECORD HOLDERS.  If the Person
surrendering a Certificate and signing the accompanying letter of transmittal is
not the Record Holder thereof, then it shall be a condition of the payment of
the Merger Consideration that such Certificate is properly endorsed to such
Person or is accompanied by appropriate stock powers, in either case signed
exactly as the name of the Record Holder appears on such Certificate, and is
otherwise in proper form for transfer, or is accompanied by appropriate evidence
of the authority of the Person surrendering such Certificate and signing the
letter of transmittal to do so on behalf of the Record Holder and that the
person requesting such exchange shall pay to the Exchange Agent in

                                       8

changed for the Merger Consideration and cancelled as provided in this Section
2.8.

          (g)  RETURN OF EXCHANGE FUND.  At any time following the 12-month
period after the Effective Time, Buyer shall be entitled to require the Exchange
Agent to deliver to it any portions of the Exchange Fund which had been made
available to the Exchange Agent and not disbursed to holders of Certificates
(including, without limitation, all interest and other income received by the
Exchange Agent in respect of all funds made available to it), and thereafter
such holders shall be entitled to look to Buyer (subject to abandoned property,
escheat and other similar laws) only as general creditors thereof with respect
to any Merger Consideration that may be payable upon due surrender of the
Certificates held by them. Notwithstanding the foregoing, neither Buyer nor the
Exchange Agent shall be liable to any holder of a Certificate for any Merger
Consideration delivered in respect of such Certificate to a public official
pursuant to any abandoned property, escheat or other similar law.

issued and outstanding immediately prior to the Effective Time shall be
converted into one share of common stock of the Surviving Corporation at the
Effective Time.

     2.10  DISSENTERS' RIGHTS.  Notwithstanding anything in this Agreement to
the contrary and unless otherwise provided by applicable law, Safety Fund Common
Stock which is issued and outstanding immediately prior to the Effective Time
and which is owned by stockholders who, pursuant to applicable law, (a) deliver
to Safety Fund in the manner provided by law, before the taking of the vote of
Safety Fund's stockholders on the Merger, a written objection to the Merger and
a written demand for the appraisal of their shares if the Merger is effected and
(b) whose shares are not voted in favor of the Merger, nor consented thereto in
writing (the "Dissenting Shares"), shall not be converted into the right to

holders thereof shall be entitled to payment of the appraised value of such
Dissenting Shares in accordance with the provisions of Chapter 156B, (S)(S)86-98
of the Massachusetts Business Corporation Law (as amended, the "MBCL").  If any
                                                                ----           
such holder shall have failed to perfect or shall have effectively withdrawn or
lost such right of appraisal, the Safety Fund Common Stock of such holder shall
thereupon be deemed to have been converted into and be exchangeable for, at the
Effective Time, the right to receive the Merger Consideration.  Buyer shall have
the right to participate in any proceeding involving dissenters' rights.

     2.11  STOCK OPTIONS.  (a)  At the Effective Time, each holder of a then
outstanding stock option to purchase Safety Fund Common Stock ("Safety Fund

     3.11  TAXES AND TAX RETURNS.  (a)  Safety Fund, all Safety Fund
Subsidiaries, and all predecessors of Safety Fund have timely filed all federal,
state, and local tax returns required by applicable law to be filed except for
filings which are filed pursuant to routine extensions permitted by law or the
failure to file which or the late filing of which would not have a Material
Adverse Effect on Safety Fund and the Safety Fund Subsidiaries, taken as a
whole.  Such returns were accurate and complete in all material respects except
where the failure to be accurate or complete would not have a Material Adverse
Effect on Safety Fund and the Safety Fund Subsidiaries, taken as a whole.

          (b)  Safety Fund, all Safety Fund Subsidiaries, and all predecessors
of Safety Fund have paid or, where payment is not required to have been made,

periods covered by such returns and as of the date hereof, including but not
limited to accruals or withholdings relating to any tax withholding, social
security or unemployment provisions of the applicable federal, state and local

on Safety Fund and the Safety Fund Subsidiaries, taken as a whole. As of the
respective dates of the Safety Fund Financial Statements in which such reserves
or accruals are established and the date hereof, neither Safety Fund nor any
Safety Fund Subsidiary had any liability for any such taxes in excess of the
amounts so paid or reserved or accruals so established which was material to

accruals are reflected in the Safety Fund Financial Statements, neither Safety
Fund nor any of the Safety Fund Subsidiaries is delinquent in the payment of any
material tax, assessment or governmental charge the failure to pay which would
have a Material Adverse Effect on Safety Fund and the Safety Fund Subsidiaries,
taken as a whole, and none of them has requested any extension of time within

instrumentality, domestic or foreign, including, without limitation, any Bank
Regulator, except (i) for applicable requirements, if any, of the Securities
Act, the Exchange Act or the laws of certain states under which a "blue sky"
filing or consent may be required, state takeover laws, and filing and

Hampshire law, (ii) for consents and approvals of or filings or registrations
with the Bank Regulators, and (iii) where failure to obtain any such consent,

obligations under this Agreement, or would not have a Material Adverse Effect on
Buyer and its subsidiaries, taken as a whole.

     4.6  REGULATORY APPROVAL.  Buyer is not aware of any reason why the
conditions set forth in Section 8.1(c) hereof would not be satisfied without
significant delay.  Buyer is not aware of any reason why the Merger cannot

which constitutes, a "takeover proposal" (as defined below), or, except to the
extent legally required for the discharge of the fiduciary duties of its Board
of Directors, recommend or endorse any takeover proposal, or participate in any
discussions or negotiations, or provide third parties with any non-public

this Section 5.2 shall prohibit Safety Fund or Safety Fund's Board from taking
and disclosing to Safety Fund's stockholders a position with respect to a tender
offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated under the
Exchange Act or making such other disclosure to Safety Fund's stockholders
which, in the judgment of the Safety Fund Board, based upon the advice of
outside counsel, may be required under applicable law, or making disclosure to
the Safety Fund's stockholders of the absence of an opinion from the Safety Fund
Investment Advisor as to the fairness of the Merger Consideration dated the date
of the Proxy Statement.  Safety Fund will take all reasonable actions necessary
or advisable to inform the appropriate individuals or entities referred to in
the first sentence hereof of the obligations undertaken herein.  Safety Fund
will notify Buyer immediately if any such inquiries or takeover proposals are
received by, any such information requested from, or any such negotiations or
discussions are sought to be initiated or continued with, Safety Fund,
indicating in reasonable detail the identity of the person making such proposal,
offer, inquiry or contact and the terms and conditions of such proposal, offer,
inquiry or contact.  As used in this Agreement, "takeover proposal" shall mean
any tender or exchange offer, proposal for a merger, consolidation or other
business combination involving Safety Fund or any of its Subsidiaries or any
proposal or offer to acquire in any manner a substantial equity interest in, or
a substantial portion of the assets of, Safety Fund or any of its Subsidiaries
other than the transactions contemplated or permitted by this Agreement or the
Option Agreement.

     5.3  CURRENT INFORMATION.  During the period from the date of this
Agreement to the Effective Time, Safety Fund will cause one or more of its
representatives to confer with representatives of Buyer and report the general
status of its ongoing operations at such times as Buyer may reasonably request.
Safety Fund will promptly notify Buyer of any material change in the normal
course of its business or in the operation of its properties and, to the extent
permitted by applicable law, of any governmental complaints, investigations or
hearings (or communications indicating that the same may be contemplated), or
the institution or the threat of material litigation involving Safety Fund.
Safety Fund will also provide Buyer such information with respect to such events
as Buyer may reasonably request from time to time.

     5.4  ACCESS TO PROPERTIES AND RECORDS.  Safety Fund shall permit Buyer
reasonable access to its properties and those of the Safety Fund Subsidiaries,

properties, operations, obligations and liabilities, including, but not limited
to, all books of account (including the general ledger), tax records, minute
books of directors' and stockholders' meetings, organizational documents, by-
laws, material contracts and agreements, filings with any regulatory authority,
litigation files, plans affecting employees, and any other business activities
or prospects in which Buyer may have a reasonable interest; provided, however,
that Safety Fund shall not be required to take any action that would provide
access to or to disclose information where such access or disclosure would
violate or prejudice the rights or business interests or confidences of any
customer or other person or would result in the waiver by it of the privilege
protecting communications between it and any of its counsel.

Board of Directors of Safety Fund will recommend to Safety Fund's stockholders
the approval of this Agreement and the transactions contemplated hereby and will
use all reasonable efforts to obtain, as promptly as practicable, the necessary
approvals by Safety Fund's stockholders of this Agreement and the transactions
contemplated hereby, provided, however, that nothing contained herein shall
prohibit the Board of Directors of Safety Fund from failing to make such a
recommendation or modifying or withdrawing its recommendation, if such Board
shall have concluded in good faith with the advice of counsel that such action
is required to prevent such Board from breaching its fiduciary duties to the
stockholders of Safety Fund, and no such action shall constitute a breach of
this Agreement.

     5.7  DISCLOSURE SUPPLEMENTS.  From time to time prior to the Effective
Time, Safety Fund will promptly supplement or amend the Schedules delivered in
connection herewith pursuant to Article III with respect to any matter hereafter
arising which, if existing, occurring or known at the date of this Agreement,
would have been required to be set forth or described in such Schedules or which
is necessary to correct any information in such Schedules which has been
rendered inaccurate thereby. No supplement or amendment to such Schedules shall
have any effect for the purpose of determining satisfaction of the conditions
set forth in Article VIII or the compliance by Safety Fund with the covenants
set forth in Section 5.1 hereof.

     5.8  FAILURE TO FULFILL CONDITIONS.  In the event that Safety Fund
determines that a condition to its obligation to complete the Merger cannot be
fulfilled and that it will not waive that condition, it will promptly notify
Buyer.

     5.9  CONSENTS AND APPROVALS OF THIRD PARTIES.  Safety Fund shall use all
reasonable efforts to obtain as soon as practicable all consents and approvals
of any other Persons necessary or desirable for the consummation of the
transactions contemplated by this Agreement.  Without limiting the generality of
the foregoing, Safety Fund may utilize the services of a professional proxy
soliciting firm to help obtain the shareholder vote required to be obtained by
it hereunder.

     5.10  ALL REASONABLE EFFORTS.  Subject to the terms and conditions herein
provided, Safety Fund agrees to use all reasonable efforts to take, or cause to
be taken, all corporate or other action and to do, or cause to be done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement.

     5.11  SAFETY FUND SUBSIDIARIES.  Safety Fund undertakes and agrees that, if
so requested by Buyer, it shall take all necessary action to facilitate the
merger of Safety Fund Subsidiaries (other than SFNB) with subsidiaries of Buyer
effective on or after the Effective Time; provided, however, that in no event
shall the Closing be delayed in order to facilitate any such merger and provided
further, however, that Safety Fund shall not be required to take any action that
could adversely affect the qualification of the Merger as a reorganization
within the meaning of Section 368(a) of the Code or the treatment of the Merger
as a pooling of interests for accounting purposes.

                                  ARTICLE VI

                              COVENANTS OF BUYER

     6.1  CONDUCT OF BUSINESS.  During the period from the date of this
Agreement to the Effective Time, except with the written consent of Safety Fund
and except as provided below, Buyer will take no action which would (i)
materially adversely affect the ability of Buyer or Safety Fund to obtain any
necessary approvals of governmental authorities required for the transactions
contemplated hereby or materially increase the period of time necessary to
obtain such approvals, or (ii) materially adversely affect its ability to
perform its covenants and agreements under this Agreement, or (iii) disqualify
the Merger as a "pooling of interests" for accounting purposes or a tax free
reorganization under Section 368 of the Code, or (iv) result in the
representations and warranties of Buyer contained in this Agreement not being
true and correct on the date of this Agreement or at any future date on or
prior to the Closing Date; provided that nothing herein contained shall preclude
Buyer from exercising its rights under the Option Agreement or from taking any
action described on Schedule 6.1 hereto.
                    ------------        

     6.2  CERTAIN BUSINESS TRANSACTIONS.  Buyer will not enter into any
agreement with respect to an Acquisition of another Person without the prior
written consent of Safety Fund if such Acquisition would (i) require the
approval of Buyer's shareholders; or (ii) involve Buyer's payment of
consideration having a value that equals or exceeds $30 million; or (iii) be
reasonably likely to result in a delay in the consummation of the Merger in any
material respect; or (iv) be reasonably likely to reduce in any material respect
the chances that the Merger will be consum-

                                       32
 
<PAGE>
 
mated in accordance with the terms of this Agreement.  Safety Fund agrees not to
withhold unreasonably or delay any response to a request by Buyer for consent
under this Section 6.2.  The term "Acquisition" shall mean Buyer's purchase or
other acquisition (including by way of merger, consolidation, share exchange or
any similar transaction) of securities representing 50% or more of the voting
power of a Person other than Safety Fund; or Buyer's purchase or other
acquisition of assets of another Person as a going concern, but shall not
include:  (i) internal reorganizations or consolidations involving subsidiaries,
(ii) foreclosures in the ordinary course of business, (iii) acquisitions of
control by a banking subsidiary in its fiduciary capacity, or (iv) the creation
of new subsidiaries other than in the context of a purchase or acquisition of
assets from another Person.

     6.3  CURRENT INFORMATION.  During the period from the date of this
Agreement to the Effective Time, Buyer will cause one or more of its
representatives to confer with representatives of Safety Fund and report the
general status of its ongoing operations at such times as Safety Fund may
reasonably request.  Buyer will promptly notify Safety Fund of any material
change in the normal course of its business or in the operation of its
properties and, to the extent permitted by applicable law, of any governmental
complaints, investigations or hearings (or communications indicating that the
same may be contemplated), or the institution or the threat of material
litigation involving Buyer.  Buyer will also provide Safety Fund such
information with respect to such events as Safety Fund may reasonably request
from time to time.

     6.4  ACCESS TO PROPERTIES AND RECORDS.  Buyer shall permit Safety Fund
reasonable access to its properties and those of its subsidiaries, and shall
disclose and make available to Safety Fund during normal business hours all of
its books, papers and records relating to the assets, stock ownership,
properties, operations, obligations and liabilities, including, but not limited
to, all books of account (including the general ledger), tax records, minute
books of directors' and stockholders' meetings, organizational documents, by-
laws, material contracts and agreements, filings with any regulatory authority,
litigation files, plans affecting employees, and any other business activities
or prospects in which Safety Fund may have a reasonable interest; provided,
however, that Buyer shall not be required to take any action that would provide
access to or to disclose information where such access or disclosure would
violate or prejudice the rights or business interests or confidences of any
customer or other person or would result in the waiver by it of the privilege
protecting communications between it and any of its counsel.

     6.5  FINANCIAL AND OTHER STATEMENTS. (a)  Promptly upon receipt thereof,
Buyer will furnish to Safety Fund copies of each annual, interim or special
audit of the books of Buyer and its subsidiaries made by its independent
accountants and copies of all internal control reports submitted to Buyer by
such accountants in connection with each annual, interim or special audit of the
books of Buyer and its subsidiaries made by such accountants.

          (b)  As soon as practicable, Buyer will furnish to Safety Fund copies
of all such financial statements and reports as it shall send to its
stockholders, the SEC, the OCC or any other regulatory authority, except as
legally prohibited thereby.

          (c)  Buyer will advise Safety Fund promptly of Buyer's receipt of any
examination report of any federal or state regulatory or examination authority
with respect to the condition or activities of Buyer or any of its subsidiaries.

                                       33
 
<PAGE>
 
          (d)  With reasonable promptness, Buyer will furnish to Safety Fund
such additional financial data as Safety Fund may reasonably request, including
without limitation, detailed monthly financial statements and loan reports.

     6.6  CONSENTS AND APPROVALS OF THIRD PARTIES.  Buyer shall use all
reasonable efforts to obtain as soon as practicable all consents and approvals
of any other Persons necessary or desirable for the consummation of the
transactions contemplated by this Agreement.  Without limiting the generality of
the foregoing, Buyer may utilize the services of a professional proxy soliciting
firm to help obtain the shareholder vote required to be obtained by it
hereunder.

     6.7  ALL REASONABLE EFFORTS.  Subject to the terms and conditions herein
provided, Buyer agrees to use all reasonable efforts to take, or cause to be
taken, all action and to do, or cause to be done, all things necessary, proper
or advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement.

     6.8  FAILURE TO FULFILL CONDITIONS.  In the event that Buyer determines
that a condition to its obligation to complete the Merger, the BHC Merger, or
the Bank Merger cannot be fulfilled and that it will not waive that condition,
it will promptly notify Safety Fund.

     6.9  DISCLOSURE SUPPLEMENTS.  From time to time prior to the Effective
Time, Buyer will promptly supplement or amend the Schedules delivered in
connection herewith pursuant to Article  with respect to any matter hereafter
arising which, if existing, occurring or known at the date of this Agreement,
would have been required to be set forth or described in such Schedules or which
is necessary to correct any information in such Schedules which has been
rendered inaccurate thereby.  No supplement or amendment to such Schedules shall
have any effect for the purpose of determining satisfaction of the conditions
set forth in Article VII.

     6.10  EMPLOYEE BENEFITS.  (a) All employees of Safety Fund and its
Subsidiaries as of the Effective Time shall become employees of Buyer or a
Subsidiary as of the Effective Time.  Nothing in this Agreement shall give any
employee of Safety Fund or its Subsidiaries a right to continuing employment
with Buyer after the Effective Time.  Any employee of Safety Fund whose
employment with Buyer is terminated after the Effective Time shall be entitled
to the same severance benefits generally available to employees of Buyer,
provided, however, that for purposes of determining eligibility for and vesting
of such severance benefits, service with Safety Fund or any Safety Fund
Subsidiary prior to the Effective Time shall be treated as service with an
"employer" to the same extent as if such persons had been employees of Buyer.  A
copy of Buyer's severance policy has previously been made available to Safety
Fund.

          (b) As soon as practicable after the Effective Time, Buyer shall
provide or cause to be provided to all employees of Safety Fund and any Safety
Fund Subsidiary who remain employed by Buyer or any of Buyer's Subsidiaries
after the Effective Time with employee benefits which, in the aggregate, are no
less favorable than those generally afforded to other employees of Buyer or
Buyer's Subsidiaries holding similar positions, subject to the terms and
conditions under which those employee benefits are made available to such
employees, provided, however, that (i) for purposes of determining eligibility
for and vesting of such employee benefits only (and not for pension benefit
accrual purposes), service with Safety Fund or any Safety Fund Subsidiary prior
to the Effective Time shall be treated as service with an "employer" to the same
extent as if such persons had been employees of Buyer, (ii) this Section 6.10
shall not be

                                       34
 
<PAGE>
 
construed to limit the ability of Buyer and its Subsidiaries to terminate the
employment of any employee or to review employee benefits programs from time to
time and to make such changes as they deem appropriate, and (iii) neither Buyer
nor any of its Subsidiaries shall be required to provide any employees or former
employees of Safety Fund with post-retirement medical benefits more favorable
than those provided to new hires of Buyer.

          (c)  Safety Fund has listed certain employment and change of control
agreements and a tin parachute plan in Schedule 6.10 hereto.  Following the
                                       -------------                       
Effective Time, Buyer shall honor or cause its Subsidiaries to honor in
accordance with their terms all such employment and change of control agreements
and the tin parachute plan and assume or cause its Subsidiaries to assume all
duties, liabilities and obligations under such agreements and  arrangements.
Buyer agrees that the consummation of the transactions contemplated hereby
constitutes a "Change in Control" as defined in the change of control agreements
entered into between Safety Fund or any Safety Fund Subsidiary and certain
officers as disclosed in Schedule 6.10 hereto.  The provisions of this Section
                         -------------                                        
6.10 are expressly intended to be for the irrevocable benefit of, and shall be
enforceable by, each director, officer, employee and former employee covered
hereby and his or her heirs and representatives.

     6.11  DIRECTORS AND OFFICERS INDEMNIFICATION AND INSURANCE.

          (a)  CONTRACTUAL INDEMNIFICATION.  In the event of any threatened or
actual claim, action, suit, proceeding or investigation, whether civil,
administrative or criminal, including, without limitation, any such claim,
action, suit, proceeding or investigation in which any Person who is now, or has
been at any time prior to the date hereof, or who becomes prior to the Effective
Time, a director or officer of Safety Fund or any Safety Fund Subsidiary (the
                                                                             
"Indemnified Parties") is, or is threatened to be, made a party, based in whole
- ---------------------                                                           
or in part on, or arising in whole or in part out of, or pertaining to, this
Agreement or any of the transactions contemplated hereby, whether in any case
asserted or arising before or after the Effective Time, the parties hereto agree
to cooperate and use their reasonable efforts to defend against and respond to
such claim, action, suit, proceedings or investigation.  It is understood and
agreed that from and after the Effective Time, Buyer shall indemnify and hold
harmless, as and to the fullest extent permitted by applicable law, each
Indemnified Party against any and all losses, claims, damages, liabilities and
fines, and amounts paid in settlement, in connection with any such threatened or
actual claim, action, suit, proceeding or investigation (whether asserted or
arising before or after the Effective Time).  In connection with any such claim,
action, suit, proceeding or investigation, (x) Buyer shall pay expenses
(including without limitation reasonable attorney fees) in advance of the final
disposition of any such claim, suit, proceeding or investigation to each
Indemnified Party to the fullest extent permitted by applicable law upon receipt
of any undertaking required by applicable law, and (y) Buyer shall use all
reasonable efforts to assist in the vigorous defense of any such matter;
provided, however, that (1) Buyer shall have the right to assume the defense
thereof and upon such assumption Buyer shall not be liable to any Indemnified
Party for any legal expenses of other counsel or any other expenses subsequently
incurred by any Indemnified Party in connection with the defense thereof, except
that if Buyer does not assume such defense or counsel for the Indemnified
Parties reasonably advises that there are issues which raise conflicts of
interest between Buyer and the Indemnified Parties, the Indemnified Parties may
retain counsel reasonably satisfactory to them after consultation with Buyer,
and Buyer shall pay the reasonable fees and expenses of such counsel for the
Indemnified Parties, (2) Buyer shall be obligated pursuant to this paragraph to
pay for only one firm of counsel for all Indemnified

                                       35
 
<PAGE>
 
Parties, (3) Buyer shall not be liable for any settlement effected without its
prior written consent (which consent shall not be unreasonably withheld) and (4)
Buyer shall have no obligation hereunder to any Indemnified Party when and if a
court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and nonappealable, that indemnification
of such Indemnified Party in the manner contemplated hereby is prohibited by
applicable law.

          (b)  PROCEDURAL LIMITATIONS.  Any Indemnified Party wishing to claim
indemnification under Section 6.11 shall, upon learning of any such claim,
action, suit, proceeding or investigation, notify Buyer thereof, provided that
the failure so to notify shall not affect the obligations of Buyer under Section
6.11 except to the extent such failure materially prejudices it.  As a condition
to receiving indemnification under Section 6.11, the party claiming
indemnification shall assign, by separate writing, to Buyer all right, title and
interest to and in proceeds of any insurance maintained or provided by Safety
Fund or Buyer or any of their respective affiliates for the benefit of claimant,
to the extent of indemnification actually received from Buyer hereunder.  Any
Person entitled to indemnification pursuant to Section 6.11 shall be required to
cooperate in the defense and investigation of any claim as to which
indemnification may be made and shall send such notices as Buyer may reasonably
request under any applicable directors and officers liability or bankers blanket
bond insurance coverage to preserve claims of which the claiming party is aware.
No person shall be entitled to indemnification under Section 6.11 if such Person
is seeking indemnification based on a claim (other than a claim arising as a
supplier to, customer of or borrower from Buyer or the Buyer Subsidiaries or
Safety Fund or the Safety Fund Subsidiaries) brought by such person or by an
entity of which such person is a general partner, executive officer, director,
trustee, beneficiary or controlling person unless such Person or entity has
waived any right to participate in any damage or other award to such claiming
party or other entity in any such action, suit or proceeding.

          (c)  CHARTER AND BY-LAWS.  All rights to indemnification and all
limitations of liability existing in favor of the Indemnified Parties as
provided in Safety Fund's Charter and By-laws, or similar governing documents of
any Safety Fund Subsidiary, as in effect as of the date hereof with respect to
claims or liabilities arising from facts or events existing or occurring prior
to the Effective Time shall survive the Merger and shall continue in full force
and effect, without any amendment thereto, for a period of six (6) years from
the Effective Time; provided, however, that all rights to indemnification in
respect of any claim asserted or made within such period shall continue until
the final disposition of such claim.  Buyer shall indemnify, defend and hold
harmless the Indemnified Parties pursuant to the rights surviving pursuant to
the preceding sentence to the full extent permitted under applicable law.

          (d)  PURCHASE OF INSURANCE.  Buyer, from and after the Effective Time,
will cause the persons who served as directors or officers of Safety Fund on or
before the Effective Time to be covered by Safety Fund's existing directors' and
officers' liability insurance policy (provided that Buyer may substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are not less advantageous than such policy) but in no event
shall any insured person be entitled under this Section 6.11 to insurance
coverage more favorable than that provided to him or her in such capacities at
the date hereof with respect to acts or omissions resulting from their service
as such on or prior to the Effective Time.  Such insurance coverage shall
commence on the Effective Date and will be provided for a period of no less than
six years after the Effective Time; provided, however, that in no event shall
Buyer be required to expend

                                       36
 
<PAGE>
 
in any year more than 150% of the current per annum amount expended by Safety
Fund to maintain or procure insurance coverage pursuant hereto.  Safety Fund
agrees to renew any such existing insurance or to purchase any "discovery
period" insurance provided for thereunder at Buyer's request.

          (e)  SUCCESSORS OR ASSIGNS.  To the extent not otherwise provided by
applicable law, contract or otherwise, and to the extent necessary under the
circumstances for Buyer's successors or assigns to be bound, in the event Buyer
or any of its successors or assigns (i) consolidates with or merges into any
other Person and shall not be the continuing or surviving corporation or entity
of such consolidation or merger, or (ii) transfers or conveys all or
substantially all of its properties and assets to any Person, proper provision
shall be made so that the successors and assigns of Buyer assume the obligations
set forth in this Section 6.11.

          (f)  THIRD PARTY BENEFICIARY.  The provisions of this Section 6.11 are
expressly intended to be for the irrevocable benefit of, and shall be
enforceable by, each director or officer covered hereby and his or her heirs and
representatives.

     6.12  STOCK EXCHANGE LISTING.  Buyer shall apply for approval to list the
shares of Buyer Common Stock to be issued in the Merger on the Stock Exchange,
subject to official notice of issuance, prior to the Effective Time.

     6.13  BUYER SUB.  Prior to the Effective Time, Buyer will take any and all
necessary action to cause (i) Buyer Sub to be organized, (ii) Buyer Sub to
become a direct or indirect wholly-owned subsidiary of Buyer, (iii) the
directors and stockholder or stockholders of Buyer Sub to approve the
transactions contemplated by this Agreement

                                  ARTICLE VII

                         REGULATORY AND OTHER MATTERS

     7.1  PROXY STATEMENT-PROSPECTUS.  For the purposes (x) of registering
Buyer's Common Stock to be issued to holders of Safety Fund's Common Stock in
connection with the Merger with the SEC under the Securities Act and applicable
state securities laws and (y) of holding the Safety Fund shareholders' meeting,
Buyer and Safety Fund shall cooperate in the preparation of a registration
statement (such registration statement, together with all and any amendments and
supplements thereto, being herein referred to as the "Registration Statement"),
                                                      ----------------------   
including a proxy statement/prospectus or statements satisfying all applicable
requirements of applicable state securities and banking laws, and of the
Securities Act and the Exchange Act, and the rules and regulations thereunder
(such proxy statement/prospectus in the form mailed by Safety Fund to the Safety
Fund shareholders, together with any and all amendments or supplements thereto,
being herein referred to as the "Proxy Statement-Prospectus").   Buyer shall
                                 --------------------------                 
file the Registration Statement with the SEC.  Each of Buyer and Safety Fund
shall use their best efforts to have the Registration Statement declared
effective under the Securities Act as promptly as practicable after such filing,
and Safety Fund shall thereafter promptly mail the Proxy Statement-Prospectus to
its stockholders.  Buyer shall also use its best efforts to obtain all necessary
state securities law or "Blue Sky" permits and approvals required to carry out
the transactions contemplated by this Agreement, and Safety Fund shall furnish
all information concerning Safety Fund and the holders of Safety Fund Common
Stock as may be reasonably requested in connection with any such

                                       37
 
<PAGE>
 
action.  Safety Fund and Buyer shall each promptly notify the other if at any
time it becomes aware that the Proxy Statement-Prospectus contains any untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements contained therein, in light
of the circumstances under which they were made, not misleading.  In such event,
Safety Fund and Buyer shall cooperate in the preparation of a supplement or
amendment to the Proxy Statement-Prospectus, which corrects such misstatement or
omission, and shall cause the same to be filed with the SEC and distributed to
stockholders of Safety Fund.

     7.2  REGULATORY APPROVALS.  Each of Safety Fund and Buyer will cooperate
with the other and use all reasonable efforts to prepare all necessary
documentation, to effect all necessary filings and to obtain all necessary
permits, consents, approvals and authorizations of all third parties and
governmental bodies necessary to consummate the transactions contemplated by
this Agreement, including without limitation the Merger, the BHC Merger, and the
Bank Merger.  Safety Fund and Buyer will furnish each other and each other's
counsel with all information concerning themselves, their subsidiaries,
directors, officers and stockholders and such other matters as may be necessary
or advisable in connection with the Proxy Statement-Prospectus and any
application, petition or any other statement or application made by or on behalf
of Safety Fund or Buyer to any governmental body in connection with the Merger,
the BHC Merger, the Bank Merger, and the other transactions contemplated by this
Agreement.  Safety Fund and Buyer shall have the right to review and approve in
advance all characterizations of the information relating to Buyer or Safety
Fund, as the case may be, and any of their respective subsidiaries, which
appear in any filing made in connection with the transactions contemplated by
this Agreement with any governmental body.  In addition, Safety Fund and Buyer
shall each furnish to the other a final copy of each such filing made in
connection with the transactions contemplated by this Agreement with any
governmental body.

     7.3  AFFILIATES; PUBLICATION OF COMBINED FINANCIAL RESULTS.  (a)  Each of
Buyer and Safety Fund shall use all reasonable efforts to cause each director,
executive officer and other person who is an "affiliate" (for purposes of Rule
145 under the Securities Act and for purposes of qualifying the Merger for
"pooling of interests" accounting treatment) of such party to deliver to the
other party hereto, as soon as practicable after the date of this Agreement, and
prior to the date of the shareholders meeting called by Safety Fund to approve
this Agreement, a written agreement, in the form of Exhibit 7.3 hereto,
                                                    -----------        
providing that such person will not sell, pledge, transfer or otherwise dispose
of any shares of Buyer Common Stock or Safety Fund Common Stock held by such
"affiliate", and, in the case of the "affiliates" of Safety Fund, the shares of
Buyer Common Stock to be received by such "affiliate" in the Merger: (1)
otherwise than in compliance with the applicable provisions of the Securities
Act and the rules and regulations thereunder or (2) unless the parties shall
have agreed that it will be impossible to obtain pooling treatment for the
Merger, during the period commencing 30 days prior to the Merger and ending at
the time of the publication of financial results covering at least 30 days of
combined operations of Buyer and Safety Fund.

          (b)  Buyer shall use its best efforts to publish no later than twenty-
five (25) days after the end of the first calendar quarter in which there are at
least thirty (30) days of post-Merger combined operations (which calendar
quarter may be the calendar quarter in which the Effective Time occurs),
combined sales and net income figures as contemplated by and in accordance with
the terms of SEC Accounting Series Release No. 135.

                              CLOSING CONDITIONS

     8.1  CONDITIONS TO EACH PARTY'S OBLIGATIONS UNDER THIS AGREEMENT.  The
respective obligations of each party under this Agreement shall be subject to
the fulfillment at or prior to the Effective Time of the following conditions,
none of which may be waived:

          (a)  STOCKHOLDER APPROVAL.  This Agreement and the transactions
contemplated hereby shall have been approved in accordance with applicable law
and Stock Exchange policy by the requisite vote of the stockholders of Safety
Fund and Buyer.

          (b)  INJUNCTIONS.  None of the parties hereto shall be subject to any

Agreement.

          (c)  REGULATORY APPROVALS. All necessary approvals, authorizations and
consents of all governmental bodies required to consummate the transactions
contemplated by this Agreement shall have been obtained and shall remain in full
force and effect and all waiting periods relating to such approvals,
authorizations or consents shall have expired; and no such approval, authoriza-
tion or consent shall include any condition or requirement, not reasonably
foreseen as of the date of this Agreement, that would, in the good faith
reasonable judgment of the Board of Directors of either Buyer or Safety Fund,
materially and adversely affect the business, operations, financial condition,
property or assets of the combined enterprise or of Safety Fund or SFNB or
otherwise materially impair the value of Safety Fund or SFNB to Buyer; provided,
however, that no condition or requirement that relates primarily to regulatory
matters existing at the date hereof with respect to Buyer's pre-Merger business
or activities shall be deemed to affect the business, operations, financial
condition, property or assets of the combined enterprise or of Safety Fund or
otherwise materially impair the value of Safety Fund to Buyer.

          (d)  EFFECTIVENESS OF REGISTRATION STATEMENT. The Registration
Statement shall have become effective under the Securities Act and no stop order
suspending the effectiveness of the Registration Statement shall have been
issued, and no proceedings for that purpose shall have been initiated or

Effective Time, each of Buyer and Safety Fund shall have received an opinion of
Arnold & Porter reasonably acceptable in form and substance to Buyer and Safety
Fund dated as of the Closing Date, substantially to the effect that, for federal
income tax purposes:

or such later date as shall have been agreed to in writing by Buyer and Safety

connection with this Agreement and the transactions contemplated hereby under
circumstances in which neither party has the right to terminate this Agreement
pursuant to Section 10.1 hereof;

          (d)  By either Safety Fund or Buyer if the stockholders of Safety Fund
or Buyer shall have voted at the Annual or Special Meeting on the transactions
contemplated by this Agreement and such vote shall not have been sufficient to
approve such transactions;

a regulatory authority whose approval is required in connection with this
Agreement and the transactions contemplated hereby, which final action (i) has
become unappealable and (ii) does not approve this Agreement or the transactions
contemplated hereby; or

          (f)  By Safety Fund, in accordance with the provisions of Section 2.12
hereof.

of Sections 10.3, 11.1, 12.1, 12.6, 12.9, and 12.10 (and of this Section 10.2)
shall survive such termination of this Agreement and remain in full force and

     (a), 10.1(c), 10.1(d), 10.1(e), or 10.1(f) hereof (other than as a result
     of a wilful breach or gross negligence by a party hereto) shall be without
     cost or expense on the part of any party to the other; and

               (2)  In the event of a termination of this Agreement pursuant to
     Section 10.1(b) hereof as a result of a breach of a representation,
     warranty or covenant which is caused by the wilful conduct or gross
     negligence of a party, such party shall (while remaining liable for any
     liabilities or damages arising out of such wilful breach or gross
     negligence) be obligated to reimburse the other party for all out-of-pocket
     costs and expenses, including, without limitation, reasonable legal,
     accounting and investment banking fees and expenses, incurred by such other
     party in connection with the entering into of this Agreement and the
     carrying out of any and all acts contemplated hereunder (collectively
     referred to as "Expenses").
                     --------   

          (c)  The payment of Expenses is not an exclusive remedy, but is in
addition to any other rights or remedies available to the parties hereto at law
or in equity and notwithstanding anything to the contrary contained herein, no
party shall be relieved or released from any liabilities or damages arising out
of its gross negligence or wilful breach of any provision of this Agreement.

          (d)  In no event shall any officer, agent or director of Safety Fund,
any Safety Fund Subsidiary, Buyer or any Buyer subsidiary, be personally liable
thereunder for any default by any party in any of its obligations hereunder
unless any such default was intentionally caused by such officer, agent or
director.

     10.3  EXPENSES.  Except as provided in Section 10.2 hereof, whether or not
the Merger is consummated, all Expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be borne by the party

printing and mailing the Proxy Statement-Prospectus and all filings with the SEC
in connection therewith shall be shared by Buyer and by Safety Fund in
accordance with the procedures set forth in Schedule 10.3 hereto, provided,
                                            -------------                  
further, however, that nothing contained herein shall limit either party's

recover any liability or damages arising out of the other party's gross
negligence or wilful breach of this Agreement.

time prior to the Effective Time (whether before or after approval thereof by

Agreement, (b) extend the time for the performance of any of the obligations or
other acts of any other party hereto, (c) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered

Agreement and the transactions contemplated hereby by the stockholders of Safety
Fund, there may not be, without further approval of such stockholders, any
amendment of this Agreement which reduces the amount or changes the form of
consideration to be delivered to Safety Fund's stockholders pursuant to this
Agreement.  This Agreement may not be amended except by an instrument in writing
signed on behalf of each of the parties hereto.  Any agreement on the part of a
party hereto to any extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party, but such waiver or failure
to insist on strict compliance with such obligation, covenant, agreement or
condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure.

                            STOCK OPTION AGREEMENT
                            ----------------------

     THIS STOCK OPTION AGREEMENT ("Option Agreement"), dated as of January 5,
1996, is by and between The Safety Fund Corporation ("Safety Fund"), a
Massachusetts corporation registered as a bank holding company under the Bank
Holding Company Act of 1956, as amended ("BHC Act"), and CFX Corporation
("CFX"), a New Hampshire corporation registered as a bank holding company under
the BHC Act.

                                   WITNESSETH
                                   ----------

     WHEREAS, the Boards of Directors of Safety Fund and CFX have approved an
Agreement and Plan of Merger ("Merger Agreement"), providing for certain
transactions pursuant to which Safety Fund would be merged with and into CFX;

     WHEREAS, as a condition to CFX's entry into the Merger Agreement and to
induce such entry, Safety Fund has agreed to grant to CFX the option set forth
herein to purchase authorized but unissued shares of Safety Fund Common Stock;

     NOW, THEREFORE, in consideration of the premises herein contained, the
parties agree as follows:

     1.  DEFINITIONS.  Capitalized terms defined in the Merger Agreement and
used herein shall have the same meanings as in the Merger Agreement.

     2.  GRANT OF OPTION.  Subject to the terms and conditions set forth herein,
Safety Fund hereby grants to CFX an option ("Option") to purchase up to 332,000
shares of Safety Fund Common Stock, at a price of $20.00 per share payable in
cash as provided in Section 4 hereof; provided, however, that in the event
Safety Fund issues or agrees to issue any shares of Safety Fund Common Stock in
breach of its obligations under the Merger Agreement at a price less than $20.00
per share (as adjusted pursuant to Section 6 hereof), the exercise price shall
be equal to such lesser price.  Notwithstanding anything else in this Agreement
to the contrary, the number of shares of Safety Fund Common Stock subject to the
Option shall be reduced to such lesser number, if any, as may from time to time
be necessary, but only for so long as may be necessary, to cause CFX not to
become an "interested stockholder" for purposes of Chapter 11OF of the General
Laws of the Commonwealth of Massachusetts.

     3.  EXERCISE OF OPTION.

          (a)  CFX may exercise the Option, in whole or part, at any time or
from time to time if a Purchase Event (as defined below) shall have occurred and
be continuing; provided that to the extent the Option shall not have been
exercised, it shall terminate and be of no further force and effect upon the
earliest to occur of (i) the Effective Time of the Merger or (ii) termination
(other than a termination resulting from a willful breach by Safety Fund of any
covenant contained therein) of the Merger Agreement in accordance with the
provisions thereof prior to the
 
<PAGE>
 
occurrence of a Subsequent Purchase Event (as defined below) or (iii) six months
after termination of the Merger Agreement if such termination follows the
occurrence of a Subsequent Purchase Event or is due to a willful breach by
Safety Fund of any covenant contained therein; and provided further that any
such exercise shall be subject to compliance with applicable provisions of law.
As used herein "Subsequent Purchase Event" shall mean a Purchase Event that
occurs after the date hereof.

          (b)  As used herein, a "Purchase Event" shall mean any of the
following events or transactions:

               (1)  any person (other than Safety Fund, any Safety Fund
subsidiary, CFX, or any CFX affiliate) shall have commenced a bona fide tender
or exchange offer to purchase shares of Safety Fund Common Stock such that upon
consummation of such offer such person would own or control 10% or more of the
outstanding shares of Safety Fund Common Stock;

               (2)  any person (other than Safety Fund or any Safety Fund
subsidiary), other than in connection with a transaction to which CFX has given
its prior written consent, shall have filed an application or notice with any
federal or state regulatory agency for clearance or approval, to (i) merge or
consolidate, or enter into any similar transaction, with Safety Fund or any
Safety Fund subsidiary, (ii) purchase, lease or otherwise acquire all or
substantially all the assets of Safety Fund or any Safety Fund subsidiary, or
(iii) purchase or otherwise acquire (including by way of merger, consolidation,
share exchange or any similar transaction) securities representing 10% or more
of the voting power of Safety Fund or any Safety Fund subsidiary;

               (3)  any person (other than Safety Fund, any Safety Fund
subsidiary, subsidiaries of Safety Fund in a fiduciary capacity, CFX, affiliates
of CFX, or subsidiaries of CFX in a fiduciary capacity) shall have acquired
beneficial ownership or the right to acquire beneficial ownership of 10% or more
of the outstanding shares of Safety Fund Common Stock (the term "beneficial
ownership" for purposes of this Option Agreement having the meaning assigned
thereto in Section 13(d) of the Exchange Act and the regulations promulgated
thereunder);

               (4)  any person (other than Safety Fund or any Safety Fund
subsidiary) shall have made a bona fide proposal to Safety Fund by public
announcement or written communication that is or becomes the subject of public
disclosure to (i) acquire Safety Fund or any Safety Fund subsidiary by merger,
consolidation, purchase of all or substantially all its assets or any other
similar transaction, or (ii) make an offer described in clause (i) above; or

               (5)  Safety Fund shall have willfully breached any covenant
contained in the Merger Agreement, which breach would entitle CFX to terminate
the Merger Agreement (without regard to the cure periods provided for therein)
and such breach shall not have been cured prior to the Notice Date (as defined
below).

          (c)  If more than one of the transactions giving rise to a Purchase
Event under Section 3(b) is undertaken or effected, then all such transactions
shall give rise only to one Purchase Event, which Purchase Event shall be deemed
continuing for all purposes hereunder until all such transactions are abandoned.
As used in this Option Agreement, "person" shall have the meanings specified in
Sections 3(a)(9) and 13(d)(3) of the Exchange Act, and shall also include
persons (other than Safety Fund, any Safety Fund subsidiary, CFX, or any CFX

                                     - 2 -
 
<PAGE>
 
affiliate), who have entered into an agreement, arrangement or understanding
(whether or not in writing), or who are acting in concert or with conscious
parallel behavior, for the purpose of acquiring, holding, voting or disposing of
any voting securities of Safety Fund (except pursuant solely to a revocable
proxy given in response to a public proxy or consent solicitation made pursuant
to, and in accordance with, the applicable provisions of the Exchange Act and
the regulations promulgated thereunder).

          (d)  In the event CFX wishes to exercise the Option, it shall send to
Safety Fund a written notice (the date of which being herein referred to as
"Notice Date") specifying (i) the total number of shares it will purchase
pursuant to such exercise, and (ii) a place and date not earlier than three
business days nor later than 60 business days from the Notice Date for the
closing of such purchase ("Closing Date"); provided that, if prior notification
to or approval of any federal or state regulatory agency is required in
connection with such purchase, CFX shall promptly file the required notice or
application for approval and shall expeditiously process the same and the period
of time that otherwise would run pursuant to this sentence shall run instead
from the date on which any required notification period has expired or been
terminated or such approval has been obtained and any requisite waiting period
shall have passed.

     4.  PAYMENT AND DELIVERY OF CERTIFICATES.

          (a)  At the closing referred to in Section 3 hereof, CFX shall pay to
Safety Fund the aggregate purchase price for the shares of Safety Fund Common
Stock purchased pursuant to the exercise of the Option in immediately available
funds by a wire transfer to a bank account designated by Safety Fund.

          (b)  At such closing, simultaneously with the delivery of cash as
provided in subsection (a), Safety Fund shall deliver to CFX a certificate or
certificates representing the number of shares of Safety Fund Common Stock
purchased by CFX, and CFX shall deliver to Safety Fund a letter agreeing that
CFX will not offer to sell or otherwise dispose of such shares in violation of
applicable law or the provisions of this Option Agreement.

          (c)  Certificates for Safety Fund Common Stock delivered at a closing
hereunder may be endorsed with a restrictive legend which shall read
substantially as follows:

     "The transfer of the shares represented by this certificate is subject to
     certain provisions of an agreement between the registered holder hereof and
     The Safety Fund Corporation and to resale restrictions arising under the
     Securities Act of 1933, as amended, a copy of which agreement is on file at
     the principal office of The Safety Fund Corporation.  A copy of such
     agreement will be provided to the holder hereof without charge upon receipt
     by The Safety Fund Corporation of a written request."

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if CFX shall have delivered to
Safety Fund a copy of a letter from the staff of the Commission, or an opinion
of counsel, in form and substance satisfactory to Safety Fund, to the effect
that such legend is not required for purposes of the Securities Act.

     5.  REPRESENTATIONS.  Safety Fund hereby represents, warrants and covenants
to CFX as follows:

                                     - 3 -
 
<PAGE>
 
          (a)  Safety Fund shall at all times maintain sufficient authorized but
unissued shares of Safety Fund Common Stock so that the option may be exercised
without authorization of additional shares of Safety Fund Common Stock.

          (b)  The shares to be issued upon due exercise, in whole or in part,
of the Option, when paid for as provided herein, will be duly authorized,
validly issued, fully paid and nonassessable.

     6.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  In the event of any change
in Safety Fund Common Stock by reason of stock dividends, split-ups,
recapitalizations, combinations, exchanges of shares or the like, the type and
number of shares subject to the Option, and the purchase price per share, as the
case may be, shall be adjusted appropriately.  In the event that any additional
shares of Safety Fund Common Stock are issued or otherwise become outstanding
after the date of this Option Agreement (other than pursuant to this Option
Agreement), the number of shares of Safety Fund Common Stock subject to the
Option shall be adjusted so that, after such issuance, it equals 19.99%. of the
number of shares of Safety Fund Common Stock then issued and outstanding without
giving effect to any shares subject or issued pursuant to the Option.  Nothing
contained in this Section 6 shall be deemed to authorize Safety Fund to breach
any provision of the Merger Agreement.

     7.  REGISTRATION RIGHTS.  Safety Fund shall, if requested by CFX, as
expeditiously as possible following the occurrence of a Purchase Event and prior
to the second anniversary thereof, file a registration statement on a form of
general use under the Securities Act if necessary in order to permit the sale or
other disposition of the shares of Safety Fund Common Stock that have been
acquired upon exercise of the Option in accordance with the intended method of
sale or other disposition requested by CFX.  CFX shall provide all information
reasonably requested by Safety Fund for inclusion in any registration statement
to be filed hereunder.  Safety Fund will use its best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 270 days from the day such registration
statement first becomes effective as may be reasonably necessary to effect such
sales or other dispositions.  The obligations of Safety Fund hereunder to file a
registration statement and to maintain its effectiveness may be suspended for
one or more periods of time not exceeding 60 days in the aggregate if the Board
of Directors of Safety Fund shall have determined that the filing of such
registration statement or the maintenance of its effectiveness would require
disclosure of non-public information that would materially and adversely affect
Safety Fund.  The first registration effected under this Section 7 shall be at
Safety Fund's expense except for underwriting commissions and the fees and
disbursements of CFX's counsel attributable to the registration of such Safety
Fund Common Stock.  A second registration may be requested hereunder at CFX's
expense.  In no event shall Safety Fund be required to effect more than two
registrations hereunder.  The filing of any registration statement hereunder may
be delayed for such period of time as may reasonably be required to facilitate
any public distribution by Safety Fund of Safety Fund Common Stock.  If
requested by CFX, in connection with any such registration, Safety Fund will
become a party to any underwriting agreement relating to the sale of such
shares, but only to the extent of obligating itself in respect of
representations, warranties, indemnities and other agreements customarily
included in such underwriting agreements.  Upon receiving any request from CFX
or assignee thereof under this Section 7, Safety Fund agrees to send a copy
thereof to CFX and to any assignee thereof known to Safety Fund, in each case by
promptly mailing the same, postage prepaid, to the address of record of

                                     - 4 -
 
<PAGE>
 
the persons entitled to receive such copies.

     8.  REPURCHASE.

          (a)  At the request of CFX at any time commencing upon the occurrence
of a Repurchase Event (as defined in subsection (c) below) and ending nine
months thereafter ("Repurchase Period"), Safety Fund shall repurchase the Option
(whether or not previously terminated) from CFX together with any shares of
Safety Fund Common Stock purchased by CFX pursuant thereto, at a price equal to
the sum of:

               (1)  the exercise price paid by CFX for any shares of Safety Fund
Common Stock acquired pursuant to the Option;

               (2)  the difference between the "market/tender offer" price for
shares of Safety Fund Common Stock (defined as the higher of the highest price
per share at which a tender or exchange offer has been made or the highest
reported sale price for shares of Safety Fund Common Stock within that portion
of the Repurchase Period preceding the date CFX gives notice of the required
repurchase under this Section 8) and the exercise price as determined pursuant
to Section 2 hereof multiplied by the number of shares of Safety Fund Common
Stock with respect to which the Option has not been exercised, but only if the
market/tender offer price is greater than such exercise price;

               (3)  the difference between the market/tender offer price (as
defined in Section 8(b) hereof) and the exercise price paid by CFX for any
shares of Safety Fund Common Stock purchased pursuant to the exercise of the
option, multiplied by the number of shares so purchased, but only if the
market/tender offer price is greater than such exercise price; and

               (4)  CFX's reasonable out-of-pocket expenses incurred in
connection with the transactions contemplated by the Merger Agreement,
including, without limitation, legal, accounting and investment banking fees.

          (b)  In the event CFX exercises its rights under this Section 8,
Safety Fund shall, within three business days thereafter, pay the required
amount to CFX in immediately available funds and CFX shall surrender to Safety
Fund the Option and the certificates evidencing the shares of Safety Fund Common
Stock purchased thereunder and CFX shall warrant that it owns such shares and
that the same are then free and clear of all liens and encumbrances; provided
that, if prior notification to the Federal Reserve Board is required in
connection with such purchase, Safety Fund shall promptly file the required
notice or application for approval and shall expeditiously process the same and
the period of time that otherwise would run pursuant to this sentence shall run
instead from the date on which any required notification period has expired or
been terminated or such approval has been obtained and any requisite waiting
period shall have passed.

          (c)  A "Repurchase Event" shall mean any of the following:

               (1)  any person (other than Safety Fund, any Safety Fund
subsidiary, CFX, or any CFX affiliate) shall have acquired beneficial ownership
of 51% or more of the outstanding shares of Safety Fund Common Stock; or

                                     - 5 -
 
<PAGE>
 
               (2)  any person (other than CFX or any CFX affiliate) shall have
entered into an agreement, arrangement or understanding (whether or not in
writing) with Safety Fund or any Safety Fund subsidiary to (i) merge or
consolidate, or enter into any similar transaction, with Safety Fund or any
Safety Fund subsidiary, (ii) purchase, lease or otherwise acquire all or
substantially all the assets of Safety Fund or any Safety Fund subsidiary, or
(iii) purchase or otherwise acquire (including by way of merger, consolidation,
share exchange or any similar transaction) securities representing 51% or more
of the voting power of Safety Fund or any Safety Fund subsidiary.

     9.  SEVERABILITY.  If any term, provision, covenant or restriction
contained in this Option Agreement is held by a court or a federal or state
regulatory agency of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions and covenants and
restrictions contained in this Option Agreement shall remain in full force and
effect, and shall in no way be affected, impaired or invalidated.  If for any
reason such court or regulatory agency determines that the Option will not
permit the holder to acquire or Safety Fund to repurchase the full number of
shares of Safety Fund Common Stock provided in Section 2 hereof (as adjusted
pursuant to Section 6 hereof), it is the express intention of Safety Fund to
allow the holder to acquire or to require Safety Fund to repurchase such lesser
number of shares as may be permissible, without any amendment or modification
hereof.

     10.  MISCELLANEOUS.

          (a)  EXPENSES.  Except as otherwise provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees and expenses of its own financial consultants, investment bankers,
accountants and counsel.

          (b)  ENTIRE AGREEMENT.  Except as otherwise expressly provided herein,
this Option Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereto, written or oral.
Notwithstanding anything to the contrary contained in this Agreement or the
Merger Agreement, this Agreement shall be deemed to amend the Confidentiality
Agreement so as to permit CFX to enter into this Agreement and exercise all its
rights hereunder, including its right to acquire Safety Fund Common Stock upon
exercise of the Option.  The terms and conditions of this Option Agreement shall
inure to the benefit of and be binding upon the parties hereto and their
respective successors and assigns.  Nothing in this Option Agreement, expressed
or implied, is intended to confer upon any party, other than the parties hereto,
and their respective successors and assigns, any rights, remedies, obligations
or liabilities under or by reason of this Option Agreement, except as expressly
provided herein.

          (c)  ASSIGNMENT.  Neither of the parties hereto may assign any of its
rights or obligations under this Option Agreement or the Option created
hereunder to any other person, without the express written consent of the other
party, except that in the event a Purchase Event shall have occurred and be
continuing CFX may assign in whole or in part its rights and obligations
hereunder; provided, however, that until the date 30 days following the date on
which the Federal Reserve Board approves an application by CFX under the BHC Act
to acquire the shares of Safety Fund Common Stock subject to the Option, CFX may
not assign its rights under the Option except in (i) a widely dispersed public
distribution, (ii) a private placement in which

                                     - 6 -
 
<PAGE>
 
no one party acquires the right to purchase in excess of 2% of the voting shares
of Safety Fund, (iii) an assignment to a single party (e.g., a broker or
investment banker) for the purpose of conducting a widely dispersed public
distribution on CFX's behalf, or (iv) any other manner approved by the Federal
Reserve Board.  If at any time prior to the expiration of the Option, CFX shall
desire to assign all or any part of the Option, other than in a manner described
in clause (i), (ii), or (iii) above, it shall give Safety Fund written notice of
the proposed transaction ("Offeror's Notice"), identifying the proposed
transferee and setting forth the terms of the proposed transaction.  An
Offeror's Notice shall be deemed an offer by CFX to Safety Fund, which may be
accepted within two business days of the receipt of such Offeror's Notice, on
the same terms and conditions and at the same price at which CFX is proposing to
transfer the Option or portion thereof to a third party.  Settlement shall be
within five business days of the date of the acceptance of the offer and the
purchase price shall be paid in immediately available funds.  In the event of
the failure or refusal of Safety Fund to purchase all of the portion of the
Option covered by the Offeror's Notice, CFX may, within 60 days from the date of
the Offeror's Notice, sell all, but not less than all, of such portion of the
Option to such third party at no less than the price specified and on terms no
more favorable than those set forth in the Offeror's Notice.

          (d)  NOTICES.  All notices or other communications which are required
or permitted hereunder shall be in writing and sufficient if delivered
personally or sent by overnight express or by registered or certified mail,
postage prepaid, addressed as provided in the Merger Agreement. A party may
change its address for notice purposes by written notice to the other party
hereto.

          (e)  COUNTERPARTS.  This Option Agreement may be executed in any
number of counterparts, and each such counterpart shall be deemed to be an
original instrument, but all such counterparts together shall constitute but one
agreement.

          (f)  SPECIFIC PERFORMANCE.  The parties agree that damages would be an
inadequate remedy for a breach of the provisions of this option Agreement by
either party hereto and that this Option Agreement may be enforced by either
party hereto through injunctive or other equitable relief.

          (g)  GOVERNING LAW.  This option Agreement shall be governed by and
construed in accordance with the laws of Massachusetts applicable to agreements
made and entirely to be performed within such state and such federal laws as may
be applicable.
