Dear Shareholder:
 
    We  are pleased to enclose your Notice of Annual Meeting and Proxy Statement
for the Annual Meeting of Shareholders  of The Safety Fund Corporation  ("Safety
Fund")  to be held on June 7, 1996, at 10:00 a.m., Eastern Daylight Time, at the
offices of Safety  Fund, located  at 470 Main  Street, Fitchburg,  Massachusetts
01420.
 
    At  the meeting you will be asked to  consider and vote on a proposed merger
of Safety Fund  with a  wholly owned subsidiary  of CFX  Corporation ("CFX"),  a
corporation  organized  under the  laws  of the  State  of New  Hampshire  and a
registered bank holding company  (the "Merger"). Immediately thereafter,  Safety
Fund  will be merged with  and into CFX, with  CFX as the surviving corporation.
Safety Fund National Bank will become a subsidiary of CFX.
 
    In the Merger, you will receive a  certain number of shares of common  stock
of  CFX for  each share of  common stock of  Safety Fund held  by you ("Exchange
Ratio") and cash in lieu of any  fractional share of CFX common stock which  you
otherwise  would  be entitled  to  receive. The  Exchange  Ratio depends  on two
principal factors. The first  factor is whether or  not the Merger is  accounted
for under applicable accounting rules as a pooling-of-interests transaction. The
second  factor is the average closing price  of CFX common stock on the American
Stock  Exchange  for  the  ten  consecutive  trading  days  preceding  the  last
regulatory  approval  required  for  consummation of  the  Merger  ("CFX Trading
Price").
 
    If the  Merger is  accounted for  as a  pooling-of-interests (or  is not  so
accounted for because of certain actions on the part of CFX), the Exchange Ratio
will  be between 1.6292 and 1.8063,  except in certain unusual circumstances. If
the Merger cannot be accounted for as a pooling-of-interests, the Exchange Ratio
will be between 1.2 and 1.6, except in certain unusual circumstances. In  either
case,  the Exchange Ratio decreases  as the CFX Trading  Price (and the value of
the CFX shares to be received by Safety Fund's shareholders) increases.
 
    CFX common stock is listed and  traded on the American Stock Exchange  under
the  symbol "CFX". The closing price of CFX common stock in composite trading on
April 24, 1996 was $14.63 per share, as reported in The Wall Street Journal.
 
    YOUR BOARD OF  DIRECTORS HAS  UNANIMOUSLY APPROVED THE  PROPOSED MERGER  AND
RECOMMENDS  A  VOTE "FOR"  THE  MERGER. The  Board  reached this  decision after
careful consideration  of a  number  of factors.  The enclosed  Proxy  Statement
contains  more  detailed information  concerning  the Board's  decision  and the
proposed transaction (including the method for determining the Exchange  Ratio).
We urge you to consider it carefully.
 
    Approval  of the Merger requires  the affirmative vote of  the holders of at
least a majority  of the shares  of Safety Fund's  common stock outstanding  and
entitled  to vote thereon. Accordingly, proxies  marked "Abstain" or shares that
are not voted will have the same effect as votes against the Merger. We urge you
to take the time to consider this important matter and vote now.
 
    In addition,  at  the  Annual Meeting  you  will  be asked  to  elect  three
directors  to serve  for the  terms for  which they  are nominated  or until the
proposed Merger is consummated. You will also be asked to ratify the appointment
of the auditors of Safety Fund for 1996.
 
    In order to make sure that your  vote is represented, indicate your vote  on
the  enclosed  proxy form,  date  and sign  it, and  return  it in  the enclosed
envelope. If you attend the meeting in person, you may revoke your proxy at  the
meeting  and vote in person. You should not send in certificates for your shares
of Safety Fund common stock at this time.
 
    On behalf of the  Board of Directors  of Safety Fund, I  thank you for  your
support and urge you to vote for approval of the Merger.
 
                                          Sincerely,
 
                                          Christopher W. Bramley

       Merger, as amended ("Agreement"), between Safety Fund and CFX Corporation
       ("CFX"), a bank holding company organized under New Hampshire law, a copy
       of which is included  as Appendix A to  the accompanying Proxy  Statement
       and  incorporated by  reference herein, pursuant  to which:  (i) a wholly
       owned subsidiary  of  CFX  will  be merged  with  and  into  Safety  Fund
       ("Merger")  followed immediately  by the merger  of Safety  Fund with and
       into CFX; and (ii) each outstanding share of common stock of Safety Fund,
       par value $5.00 per share, would be converted into a number of shares  of
       the  common stock of  CFX, par value  $0.66 2/3 per  share, determined in
       accordance with  the terms  of the  Agreement, and  cash in  lieu of  any
       fractional share;
 
    2.   To elect three directors to serve  for terms expiring in 1999, or until

    3.  To ratify the  appointment of KPMG Peat  Marwick LLP as the  independent

    Any  shareholder entitled to vote at the  Annual Meeting on the Merger shall

                                          Sincerely,

                                PROXY STATEMENT
                                      FOR
                         ANNUAL MEETING OF SHAREHOLDERS
                            TO BE HELD JUNE 7, 1996
                            ------------------------
 
                                  INTRODUCTION
 
    This  Proxy Statement is being furnished  to shareholders of The Safety Fund
Corporation ("Safety Fund") in  connection with the  solicitation of proxies  by
the  Board  of  Directors  of Safety  Fund  for  use at  the  Annual  Meeting of
Shareholders, and any adjournment thereof, to be held at the time and place  set
forth  in the accompanying notice ("Annual Meeting"). It is anticipated that the
mailing of this Proxy Statement and the enclosed proxy card will commence on  or
about May 1, 1996.
 
    At  the Annual Meeting, shareholders of Safety Fund will be asked to approve
an Agreement and Plan of  Merger, dated as of  January 5, 1996, as  subsequently
amended  ("Agreement"), providing  for the merger  ("Merger") of  a wholly owned
subsidiary of CFX  Corporation ("CFX") with  and into Safety  Fund, with  Safety
Fund   as   the  surviving   corporation  ("Surviving   Corporation"),  followed
immediately by  the merger  of Safety  Fund into  CFX. CFX  is a  New  Hampshire
corporation  and a registered bank holding company. The Agreement is attached to
this Proxy Statement as Appendix A.
 
    At the Effective Time  (as defined below), each  share of common stock,  par
value  $5.00 per share, of  Safety Fund ("Safety Fund  Common Stock") issued and
outstanding immediately prior to the Effective Time (each such share to  include
an  attached right  issued pursuant to  the Shareholder Rights  Plan (as defined
below)) other than Dissenting Shares (as defined in the Agreement) and except as
otherwise provided in the Agreement, will be converted into an amount of  common
stock,  par value $0.66 2/3 per share, of  CFX ("CFX Common Stock") equal to one
share multiplied by the appropriate Exchange  Ratio (as defined below) and  cash
in lieu of any fractional share of CFX Common Stock.
 
    The  number of shares of  CFX Common Stock to be  received for each share of
Safety Fund Common Stock  ("Exchange Ratio") depends  on two principal  factors.
The  first factor is whether (as the parties expect) the Merger may be accounted
for under  the pooling-of-interests  method of  accounting. Thus,  the  Exchange
Ratio  depends on whether  CFX, after consulting  with its independent auditors,
determines by the close of business on the business day preceding the  Effective
Time   that  the  Merger  qualifies   for  the  pooling-of-interests  method  of
accounting, or does not so  qualify as a result of  actions by CFX in breach  of
the  Agreement  ("Pooling  Determination").  The second  factor  is  the average
closing price of CFX  Common Stock on the  American Stock Exchange ("AMEX")  for
the ten consecutive trading days preceding the last regulatory approval required
for  consummation of the Merger ("CFX Trading  Price"). At any given price level
of CFX Common Stock, the number of shares of CFX Common Stock to be received for
each share of Safety Fund Common Stock will be less under a purchase  accounting
than under a pooling-of-interests accounting. The exercise of dissenters' rights
by  holders of ten  percent or more  of Safety Fund  Common Stock would preclude
pooling treatment. For  a more  complete description  of the  Agreement and  the
differences  in  accounting  treatment, see  "PROPOSED  MERGER --  Terms  of the
Merger" and "-- Accounting Treatment."
 
    The following tables show the Exchange  Ratio at various CFX Trading  Prices
if  a Pooling Determination is made or is not made, together with the Per Safety
Fund Share Value in each case. The Per Safety Fund Share Value is calculated  by
multiplying  the  CFX  Trading  Price  by  the  applicable  Exchange  Ratio, and
represents the value of a  share of CFX Common Stock  that would be received  in
the  Merger for each share of Safety Fund  Common Stock based on the CFX Trading
Price. The CFX
 
                                       1
<PAGE>
Trading Price is based on the CFX trading price on AMEX for the ten trading days
prior to receipt of the last  regulatory approval necessary for consummation  of
the  Merger and thus  could be determined  several weeks prior  to the Effective
Time. The market price of  CFX Common Stock at  the Effective Time could  differ
from  the CFX Trading Price used to determine the Exchange Ratio, and the actual
value of the shares  issued in the  Merger therefore could  differ from the  Per
Safety Fund Share Value.

(1)  If a Pooling Determination  is made, Safety Fund by  action of its Board of
    Directors may, but  need not,  seek to terminate  the Agreement  if the  CFX
    Trading Price is below $11.66. If Safety Fund does not seek to terminate the
    Agreement,  the Exchange Ratio would be 1.806  and the Per Safety Fund Share
    Value would  be less  than $21.06.  If Safety  Fund seeks  to terminate  the
    Agreement,  CFX may  adjust the Exchange  Ratio to the  amount determined by
    dividing $21.06 by  the CFX Trading  Price (resulting in  a Per Safety  Fund
    Share  Value of $21.06) and  the Merger would be  consummated on that basis.
    Alternatively, CFX could do nothing in response, in which case the Agreement
    would terminate.

(1) If a Pooling Determination is not  made, Safety Fund by action of its  Board
    of  Directors may, but need not, seek  to terminate the Agreement if the CFX
    Trading Price is below $12.50. If Safety Fund does not seek to terminate the
    Agreement, the Exchange Ratio would be  1.600 and the Per Safety Fund  Share
    Value  would be  less than  $20.00. If  Safety Fund  seeks to  terminate the
    Agreement, CFX may  adjust the Exchange  Ratio to the  amount determined  by
    dividing  $20.00 by the CFX Trading Price or make an additional cash payment
    (in either case resulting in  a Per Safety Fund  Share Value of $20.00)  and
    the  Merger would be consummated on  that basis. Alternatively, CFX could do
    nothing in response, in which case the Agreement would terminate.

Merger,  see the graphs depicting the  pricing mechanism in "SUMMARY -- Proposed

    This summary is necessarily general and abbreviated and has been prepared to
assist shareholders in their review of this Proxy Statement. This summary is not
intended to  be a  complete explanation  of the  matters covered  in this  Proxy
Statement  and is qualified  in all respects  by reference to  the more detailed

THE MEETING
 
    The Annual Meeting of Shareholders  of Safety Fund will  be held on June  7,
1996,  at  10:00 a.m.  Eastern Daylight  Time,  at the  offices of  Safety Fund,
located at  470 Main  Street, Fitchburg,  Massachusetts 01420.  Only holders  of
record  of Safety Fund Common  Stock at the close of  business on April 24, 1996
will be  entitled to  notice of  and to  vote at  such Annual  Meeting  ("Record
Date").  At  such  date,  1,660,665  shares of  Safety  Fund  Common  Stock were
outstanding and entitled to vote. For additional information with respect to the
Annual Meeting and the voting rights of shareholders, see "MEETING INFORMATION."
 
THE PROPOSED MERGER
 
    At the  Effective Time,  a wholly  owned subsidiary  of CFX  formed for  the
purpose  of effectuating the  Merger will be  merged with and  into Safety Fund,
with Safety Fund  as the surviving  corporation. Immediately thereafter,  Safety
Fund  will be  merged with  and into  CFX, whereupon  the separate  existence of
Safety Fund will cease. CFX, as the surviving entity in these transactions, will
continue unaffected and  unimpaired by such  transactions. Upon consummation  of
the Merger, SFNB will become a wholly-owned subsidiary of CFX.
 
    At  the Effective Time,  each share of  Safety Fund Common  Stock issued and
outstanding immediately prior to the Effective Time (each such share to  include
an attached right issued pursuant to the shareholder rights agreement adopted by
Safety  Fund on  the date of  the Agreement ("Shareholder  Rights Plan")), other
than Dissenting Shares and except as  otherwise provided in the Agreement,  will
be converted into an amount of CFX Common Stock equal to one share multiplied by
the  appropriate Exchange Ratio and cash in  lieu of any fractional share of CFX
Common Stock.
 
    The Exchange Ratio  depends on two  principal factors. The  first factor  is
whether a Pooling Determination is made and the second factor is the CFX Trading
Price. Although the parties expect that the transaction will be accounted for as
a  pooling-of-interests, the Agreement provides  for alternative Exchange Ratios
if a  Pooling  Determination  is not  made  in  order that  the  Merger  may  be
consummated  as a purchase transaction if necessary. See "PROPOSAL I -- PROPOSED
MERGER -- Background of the Merger;" and "-- Accounting Treatment." The Exchange
Ratio will be 1.7 if a Pooling  Determination is made and the CFX Trading  Price
is  between $13.21  and $17.87.  The Exchange  Ratio will  be 1.52  if a Pooling
Determination is  not made  and the  CFX  Trading Price  is between  $13.16  and
$16.44. The parties have agreed to other Exchange Ratios (based on whether there
is  a Pooling Determination and on the  CFX Trading Price) under which, over the
entire range  of  Exchange Ratios,  as  the  CFX Trading  Price  increases,  the
Exchange Ratio decreases and the Per
 
                                       7
<PAGE>
Safety  Fund Share Value increases. The  Agreement provides means of determining
the Exchange  Ratio at  other  CFX Trading  Prices.  This pricing  mechanism  is
depicted in tabular form in "INTRODUCTION" and in the following graphs:

<PAGE>
    If  the CFX Trading Price is less than $11.65 and a Pooling Determination is
made or the CFX Trading Price is less than $12.50 and a Pooling Determination is
not made, Safety Fund  by action of  its Board of Directors  may, but need  not,
seek  to terminate the  Agreement by giving  written notice to  CFX prior to the
third day preceding  the Closing Date  (as defined below).  Within two  business
days thereafter, CFX may elect to increase the Exchange Ratio (or pay additional
cash  where a Pooling Determination has not  been made) pursuant to the terms of
the Agreement. If CFX makes any such election, the Agreement will not  terminate
and  the Merger may  be consummated at  the increased Exchange  Ratio or payment
elected by CFX.  See "PROPOSAL I  -- PROPOSED  MERGER -- Effective  Time of  the
Merger; Termination."
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
    Subsequent  to  the  Merger,  those  persons  serving  as  directors  of CFX
immediately prior to the Effective Time  will continue to serve as directors  of
CFX,  together  with  four  current directors  of  Safety  Fund,  Christopher W.
Bramley, P. Kevin  Condron, William  E. Aubuchon, III  and David  R. Grenon.  In
addition,  nine of those persons currently serving  as directors of SFNB will be
selected by CFX, after  consultation with Safety Fund,  to continue to serve  as
directors  of SFNB for at least three  years from the Effective Time, subject to
certain considerations, and CFX initially will elect up to three additional  CFX
representatives  as directors  of SFNB. SFNB  will continue its  operations as a
subsidiary of CFX for at least three  years from the Effective Time, subject  to
certain  considerations. See  "PROPOSAL I --  PROPOSED MERGER  -- Management and
Operations After  the Merger"  and  "PROPOSAL II  --  ELECTION OF  DIRECTORS  --
Information Regarding Directors and Nominees."
 
EFFECT ON EMPLOYEES AND BENEFIT PLANS
 
    The  Agreement provides  for the assumption  by CFX  of employment contracts
that Safety Fund  (and/or SFNB)  currently has with  Christopher Bramley,  James
Garvey  and Stephen R.  Shirley, executive officers of  Safety Fund and/or SFNB.
Pursuant to  those  employment contracts,  the  officers would  be  entitled  to
receive  severance  benefits  if  a  "terminating  event"  (as  defined  in  the
contracts) occurs within one year (with  respect to Messrs. Shirley and  Garvey)
or three years (with respect to Mr. Bramley) following a "change in control" (as
defined  in the contracts). The Merger constitutes a change in control under the
contracts. The severance benefits payable to Messrs. Shirley and Garvey would be
equal to  one  year's  annual  base  salary  (currently  $110,000  and  $99,000,
respectively),  payable over a twelve  month period and offset  by 50 percent of
any wages earned  from other employment.  The severance benefit  payable to  Mr.
Bramley  would  be  equal to  $400,000,  payable in  one  lump sum,  or,  at Mr.
Bramley's option, continuation  of his salary  (currently $211,600) and  certain
employee  benefits for  the remainder  of his  contract (which  was amended with
CFX's consent on January 5, 1996 to have a rolling two-year rather than one-year
term). The Agreement also contains  provisions relating to, among other  things,
employee   benefits,  including  the  continuation  of  Safety  Fund's  employee
severance plan (which is  comparable to a  similar plan provided  by CFX to  its
employees),  indemnification  of  directors  and  officers  and  maintenance  of
directors' and officers' liability insurance  after the Merger. See "PROPOSAL  I
- -- PROPOSED MERGER -- Effect on Employees and Benefit Plans" and "PROPOSAL II --
ELECTION OF DIRECTORS -- Executive Compensation and Other Information."
 
REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The  Board of Directors of Safety  Fund has unanimously adopted a resolution
approving the Agreement and unanimously recommends approval and adoption of  the
Agreement  by Safety Fund's shareholders. The  Safety Fund Board believes in its
business judgment that  the terms  of the  Agreement are  fair and  in the  best
interests  of Safety Fund  and its shareholders  and that the  Exchange Ratio is
fair and  reasonable  to the  shareholders  of Safety  Fund.  The terms  of  the
Agreement,  including the  Exchange Ratio,  were reached  on the  basis of arms'
length negotiations between Safety Fund and  CFX. In the course of reaching  its
decision  to  approve  the Agreement,  the  Board  of Directors  of  Safety Fund
consulted with Foley,  Hoag &  Eliot, its  legal advisors,  regarding the  legal
terms  of  the  Agreement  and  the  Board  of  Directors'  obligations  in  its
consideration thereof, and with McConnell,
 
                                       9
<PAGE>
Budd, & Downes, Inc.  ("MB&D"), its financial  advisor, regarding the  financial
terms and fairness, from a financial point of view, of the Exchange Ratio in the
proposed  Merger. See "PROPOSAL I -- PROPOSED  MERGER -- Reasons for the Merger;
Recommendation of  the Board  of Directors"  and "--  Opinion of  the  Financial
Advisor."
 
OPINION OF THE FINANCIAL ADVISOR
 
    MB&D,  financial  advisor to  Safety  Fund, has  delivered  to the  Board of
Directors of Safety  Fund its  written opinion,  as of  the date  of this  Proxy
Statement,  that the Exchange Ratio is fair,  from a financial point of view, to
Safety Fund's shareholders. The full text of the opinion of MB&D dated as of the
date of  this  Proxy  Statement,  which sets  forth  assumptions  made,  matters
considered  and limits on the  review undertaken by MB&D,  is attached hereto as
Appendix C. Shareholders are urged to read this opinion in its entirety.  MB&D's
opinion  is  directed only  to  the Exchange  Ratio  and does  not  constitute a
recommendation to any  shareholder of  Safety Fund  as to  how such  shareholder
should vote at the Annual Meeting. See "PROPOSAL I -- PROPOSED MERGER -- Opinion
of the Financial Advisor."
 
VOTE REQUIRED
 
    Safety  Fund believes and has been advised  by its counsel that, pursuant to
its Articles  of Organization  (and  consistent with  Massachusetts  corporation
law),  the Merger must be approved by the  affirmative vote of the holders of at
least a  majority of  the shares  of Safety  Fund Common  Stock outstanding  and
entitled  to vote thereon.  One of Safety Fund's  shareholders, David G. Massad,
has informed Safety Fund through his counsel that he believes the Merger must be
approved by at least two-thirds of such shares. For information about the course
of prior communications between Safety Fund  and Mr. Massad, see "PROPOSAL I  --
PROPOSED  MERGER  -- Background  of  the Merger."  Safety  Fund has  engaged the
services of a proxy solicitor and will attempt to obtain the votes of as many of
its shareholders  as is  reasonably practicable.  However, Safety  Fund and  CFX
intend  to proceed with the consummation of  the Merger if the proposal receives
the approval of  at least  a majority  of the  shares of  stock outstanding  and
entitled  to vote thereon, assuming the other  conditions to the closing are met
or waived.
 
    The nominees for director  who receive the highest  number of votes cast  at
the Annual Meeting will be elected to serve on the Board. The appointment of the
independent  auditors of Safety Fund must be ratified by the affirmative vote of
the holders of a majority  of the outstanding shares  of stock entitled to  vote
thereon, present and voting, assuming a quorum is present.
 
    Directors  and officers  of Safety Fund  and affiliates of  such persons had
sole or shared voting power with respect to 196,234 shares of Safety Fund Common
Stock, representing 11.82 percent of Safety Fund Common Stock outstanding as  of
February  16,  1996. As  of  that date,  the Trust  Department  of SFNB  held an
aggregate of 9,499 shares  of Safety Fund Common  Stock over which it  exercises
shared  voting  authority, in  a  fiduciary capacity  for  the benefit  of other
persons. The Trust Department of SFNB  will vote such shares in accordance  with
the  terms of the governing trust  document, applicable law and SFNB's fiduciary
policies.
 
    CFX has entered into  agreements ("Voting Agreements")  with each member  of
the  Board of Directors of  Safety Fund, whereby each  such person has agreed to
vote all shares of Safety Fund Common Stock  that he or she is entitled to  vote
in  favor of  the Agreement,  not including  shares held  by such  director in a
fiduciary capacity.  See  "MEETING  INFORMATION  --  Voting  and  Revocation  of
Proxies."
 
DISSENTERS' RIGHTS
 
    Under  Massachusetts law, holders of Safety Fund Common Stock have the right
to dissent from  the Merger and  receive payment  equal to the  "fair value"  of
their  shares upon compliance  with applicable provisions  of Massachusetts law,
the full text of which  is attached as Appendix D  to this Proxy Statement.  See
"PROPOSAL I -- PROPOSED MERGER -- Rights of Dissenting Shareholders."
 
                                       10
<PAGE>
CONDITIONS; TERMINATION
 
    Consummation  of  the  Merger is  subject  to  satisfaction of  a  number of
conditions, including approval of  the Agreement by  the shareholders of  Safety
Fund  and CFX, and the receipt of  all regulatory approvals required or mutually
deemed necessary in connection  with the Merger. The  approval of the Merger  by
CFX  shareholders will be solicited at the Annual Meeting of Shareholders of CFX
scheduled to be held on May 31, 1996.
 
    Substantially all of  the conditions to  consummation of the  Merger may  be
waived at any time in a writing signed by both parties, and the Agreement may be
amended  at any time, by written agreement  of the parties, except that any such
waiver or amendment executed  after approval of the  Agreement by Safety  Fund's
shareholders  which reduces the amount or  form of consideration to be delivered
to such shareholders pursuant to the Agreement requires further approval of such
shareholders.  See  "PROPOSAL  I  --  PROPOSED  MERGER  --  Representations  and
Warranties; Conditions to the Merger; Waiver."
 
    In  addition, the Agreement may be terminated  by either CFX or Safety Fund,
either before or after shareholder approval, under certain circumstances. Safety
Fund may  also terminate  the Agreement  if the  CFX Trading  Price is  below  a
certain  price and CFX does not elect  to increase the Exchange Ratio (or, under
certain circumstances, make  an additional cash  payment in lieu  thereof) to  a
designated  Per Safety Fund Share  Value. See "PROPOSAL I  -- PROPOSED MERGER --
Effective Time of the Merger; Termination."
 
STOCK OPTION AGREEMENT
 
    In connection with execution of the Agreement, Safety Fund and CFX  executed
a  Stock Option  Agreement ("Stock Option  Agreement") pursuant  to which Safety
Fund granted CFX an option ("Option")  to purchase up to 332,000 authorized  but
unissued  shares of  Safety Fund  Common Stock  (constituting approximately 16.7
percent of the  shares of  Safety Fund Common  Stock that  would be  outstanding
following  the exercise of the Option) at a  price of $20 per share, such number
of  shares  and  exercise  price  being  subject  to  adjustment  under  certain
circumstances.   The  Option  is  exercisable   only  upon  the  occurrence  and
continuation of certain events that could jeopardize consummation of the  Merger
pursuant to the terms of the Agreement, one of which has occurred. See "PROPOSAL
I -- PROPOSED MERGER -- Stock Option Agreement" and the text of the Stock Option
Agreement, attached hereto as Appendix B.
 
REGULATORY AND OTHER APPROVALS
 
    CFX  has filed  an application  with the Board  of Governors  of the Federal
Reserve System ("Federal Reserve")  for prior approval of  the Merger under  the
BHCA,  and  with  the Massachusetts  Board  of Bank  Incorporation  ("MBBI") for
approval of the Merger. The BHCA provides that the Merger may not be consummated
until applicable periods have lapsed after Federal Reserve approval is received.
An agreement will also be negotiated  between CFX and the Massachusetts  Housing
Partnership  Fund  ("MHP  Fund")  for  participation by  CFX  in  the  Fund. See
"PROPOSAL I -- PROPOSED MERGER -- Regulatory and Other Approvals."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a  summary of the anticipated  material federal income  tax
consequences  of the  Merger to  shareholders of  Safety Fund.  A more extensive
summary is set forth under the heading "PROPOSAL I -- PROPOSED MERGER -- Certain
Federal Income Tax Consequences." Each of Safety Fund's shareholders should read
in full the detailed description of the material federal income tax consequences
under that heading. Moreover, because of the complexities of the federal  income
tax   laws  and  because  the  tax   consequences  may  vary  depending  upon  a
shareholder's individual circumstances or tax status, shareholders are  strongly
encouraged  to  consult with  their personal  tax advisors  with respect  to the
specific tax consequences of the Merger to them, including the tax  consequences
of applicable federal, state, local, foreign or other laws.
 
                                       11
<PAGE>
    CFX  has received an opinion from Arnold & Porter concerning certain federal
income tax consequences of the Merger. CFX and Safety Fund have provided  Arnold
&  Porter  with the  facts, representations  and assumptions  on which  Arnold &
Porter relied in rendering its opinion, which information is consistent with the
state of facts  that CFX  and Safety  Fund believe will  be existing  as of  the
Effective  Time, including  (but not limited  to) an assumption  that other than
cash paid to dissenters and cash paid in lieu of fractional shares, no cash will
be paid to Safety  Fund's shareholders pursuant to  the Merger. With respect  to
the  possibility of  an additional cash  payment if no  Pooling Determination is
made, see  "PROPOSAL  I  --  PROPOSED  MERGER  --  Certain  Federal  Income  Tax
Consequences."  Based on such  facts, representations and  assumptions, Arnold &
Porter has opined  that, among  other things,  the Merger,  when consummated  in
accordance  with  the  Agreement  and certain  related  agreements,  either will
constitute or will  be part of  a reorganization within  the meaning of  Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code").
 
    Additional  federal  income tax  consequences of  the Merger,  including the
federal income tax consequences of  exercising dissenters' rights and  receiving
cash  in lieu of a fractional share  interest in CFX Common Stock, are discussed
under the heading "PROPOSAL I --  PROPOSED MERGER -- Certain Federal Income  Tax
Consequences."
 
ACCOUNTING TREATMENT
 
    The  parties to  the Agreement expect  the Merger  to be accounted  for as a
pooling-of-interests under generally accepted  accounting principles. Not  later
than  the second  business day preceding  the Effective Time,  CFX shall consult
with its independent auditors to determine whether the Merger qualifies for such
treatment or will be required to be  accounted for under the purchase method  of
accounting.  The ability to account for  the Merger as a pooling-of-interests is
not a condition to the Merger but  may affect the Exchange Ratio. The  Agreement
provides  for alternative Exchange  Ratio calculations so  that the Merger still
may be consummated in  the event that  the Merger cannot be  accounted for as  a
pooling-of-interests.  See  "PROPOSAL  I  -- PROPOSED  MERGER  --  Terms  of the
Merger," "--  Effective Time  of  the Merger;  Termination" and  "--  Accounting
Treatment."
 
EFFECTIVE TIME OF THE MERGER
 
    CFX  and Safety Fund each anticipate that  the Effective Time will occur and
the Merger will be consummated in the second half of 1996. However, consummation
of the Merger could be delayed and there  can be no assurances as to if or  when
the  Merger will be consummated. See "PROPOSAL I -- PROPOSED MERGER -- Effective
Time of the Merger; Termination."
 
SURRENDER OF CERTIFICATES
 
    Within three business days after the  Effective Time, notice will be  mailed
to  holders of  Safety Fund  Common Stock  regarding the  manner in  which their
certificates representing  shares  of such  Safety  Fund Common  Stock  will  be
exchanged  for certificates representing shares of  CFX Common Stock and cash in
lieu of fractional shares.  Shareholders should not  send in their  certificates
until  they receive further instructions. See  "PROPOSAL I -- PROPOSED MERGER --
Surrender of Certificates."
 
CERTAIN DIFFERENCES IN THE RIGHTS OF SHAREHOLDERS
 
    Upon  completion  of   the  Merger,   shareholders  of   Safety  Fund   will
automatically  become  shareholders of  CFX  and their  rights  as such  will be
governed by CFX's Articles of Incorporation and Bylaws and by New Hampshire law.
The rights  of shareholders  of Safety  Fund currently  are governed  by  Safety
Fund's  Articles of  Organization, as amended,  and Bylaws  and by Massachusetts
law. The rights of  shareholders of CFX are  different in certain respects  from
the rights of shareholders of Safety Fund. See "PROPOSAL I -- PROPOSED MERGER --
Certain Differences in the Rights of Shareholders."

(1)  Safety Fund was listed on the Nasdaq Stock Market on December 12, 1995. The
    high and low sales  prices reported by Nasdaq  for the period from  December
    12, 1995 through December 31, 1995 were $26.00 and $18.50, respectively.
 
    No  assurance can be given as to what the CFX Trading Price will be when and
if the Merger is consummated. Shareholders of Safety Fund are advised to  obtain
current market quotations for CFX Common Stock.
 
    The  amount of future dividends  paid by CFX will  be determined in light of
CFX's results  of operations,  financial condition,  regulatory constraints  and
other  factors deemed relevant by  CFX's Board of Directors.  In order to comply
with technical  financial accounting  rules related  to the  payment of  special
dividends preceding a business combination, the CFX Board has determined to omit
CFX's  regular cash  dividend for  the second quarter  of 1996.  Omission of the
second quarter dividend in an amount equal  to the special dividend paid by  CFX
in  January 1996  is necessary  to permit  CFX to  account for  the Merger  as a
pooling  transaction.  See  "PROPOSAL  I   --  PROPOSED  MERGER  --   Accounting
Treatment."  CFX expects to resume normal  dividends during the third quarter of
1996. The ability to maintain dividends in the future also could be affected  by
the  level  of core  earnings, economic  conditions, credit  quality, regulatory
policies, capital  needs, growth  objectives, the  ability of  bank and  nonbank
subsidiaries  to  upstream  dividends to  CFX  and other  relevant  factors. CFX
engages in  no  business  other than  acting  as  the holding  company  for  its
subsidiaries.  The only funds available to CFX  for the payment of dividends are
cash and cash equivalents held at  the holding company level, dividends paid  to
CFX  by its subsidiaries and  borrowings. See "CERTAIN REGULATORY CONSIDERATIONS
- -- Restrictions on Payment of Dividends."

share data  for  CFX Common  Stock  (with Safety  Fund  only), (iii)  pro  forma
combined  per share data for CFX Common Stock (with Safety Fund and Milford) and
(iv)  equivalent  per  share  data  for  Safety  Fund  Common  Stock  reflecting
consummation  of the Merger only and consummation  of the Merger and the Milford
Acquisition. The first table presents pro forma information at an Exchange Ratio
of 1.7  assuming  that the  Pooling  Determination  is made.  The  second  table
presents pro forma information at an Exchange Ratio of 1.52 assuming the Pooling
Determination  is  not made.  The CFX  pro  forma data  (with Safety  Fund only)
represents the effect of the Merger on  a share of CFX Common Stock. The  Safety
Fund  equivalent pro forma data  represents the CFX pro  forma data (with Safety
Fund only) multiplied by  1.7 and 1.52, respectively,  and thereby reflects  the
effect of the Merger on a share of Safety Fund Common Stock.
 
    The  CFX pro forma combined data (with Safety Fund and Milford) is presented
assuming the  Milford Acquisition  is accounted  for as  a  pooling-of-interests
transaction  at an exchange ratio of 2.6446  shares of CFX Common Stock for each
share of  Milford  common stock.  The  actual  exchange ratios  in  the  Milford
Acquisition  will depend on the market price  of CFX Common Stock during the ten
trading days preceding  the last  regulatory approval required  for the  Milford
Acquisition.  The CFX  pro forma  combined (with  Safety Fund  and Milford) data
represents the effect of the  Merger and the Milford  Acquisition on a share  of
CFX Common Stock. The Safety Fund equivalent pro forma data (assuming the Merger
and Milford Acquisition) represents the CFX pro forma combined data (with Safety
Fund  and  Milford) multiplied  by the  applicable Exchange  Ratio (1.7  for the
pooling-of-interests table and 1.52 for the purchase table) and thereby reflects
the effect of the two mergers on  a share of Safety Fund Common Stock.  Earnings
per  share data is based on net earnings before cumulative effects of changes in
accounting principles for all companies.
 
    The information is derived from  the historical financial statements of  CFX
and  Milford, including the related notes  thereto, incorporated by reference in
this Proxy Statement, and  the historical financial  statements of Safety  Fund,
including  the related  notes thereto, appearing  elsewhere herein,  and the pro
forma combined financial information giving effect to the Merger and the Milford
Acquisition, appearing elsewhere herein, and should be read in conjunction  with
such  information. The pro forma data is presented for comparative purposes only
and is not necessarily indicative of the combined financial position or  results
of  operations  that  would  have  been  realized  had  the  Merger  and Milford
Acquisition been consummated during the periods or as of the dates for which the
pro forma  data is  presented  or which  will be  attained  in the  future.  See
"AVAILABLE   INFORMATION;  DOCUMENTS  INCORPORATED  BY  REFERENCE,"  "PRO  FORMA
CONSOLIDATED FINANCIAL INFORMATION (UNAUDITED)" and the 1995 Safety Fund  Annual
Report to Shareholders that accompanies this Proxy Statement. Furthermore, there
can  be no assurance that  the CFX Trading Price will  be such that the Exchange
Ratio would be 1.7 for a pooling-of-interests transaction or 1.52 for a purchase
transaction or  that  the  exchange  ratio  would  be  2.6446  for  the  Milford
Acquisition. See "PROPOSED MERGER -- Terms of the Merger."

                                CFX CORPORATION
                  NOTES TO SELECTED HISTORICAL FINANCIAL DATA
 
(1)  Prior   period  financial   data   has  been   restated  to   reflect   the
    pooling-of-interests  with Orange  Savings Bank, CFX's  3 for  2 stock split
    declared on June 13,  1995 to shareholders  of record on  June 23, 1995  and
    CFX's  5% stock  dividend declared on  December 12, 1995  to shareholders of
    record on December 22, 1995.
 
(2) On September 1, 1993, CFX,  through its subsidiary, Cheshire County  Savings
    Bank,  acquired the remaining 52.4%  of Colonial Mortgage, Inc. ("Colonial")
    (renamed CFX Mortgage, Inc.). Previously,  CFX owned 47.6% of Colonial  and,
    as  a result of the purchase, Colonial became a wholly owned subsidiary. The
    transaction was accounted for by the purchase method of accounting.
 
(3) On September 7, 1991, CFX, through its subsidiary, the Valley Bank, acquired
    certain assets and assumed  all deposits of The  Family Bank and Trust.  The
    Family  Bank and Trust had been declared insolvent by the New Hampshire Bank
    Commissioner  and  placed   into  Federal   Deposit  Insurance   Corporation
    receivership on September 6, 1991.
 
(4)  Statement of Financial Accounting Standards No. 109, "Accounting for Income

              SELECTED UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
    The  following  tables  set  forth  certain  unaudited  pro  forma  combined
financial data for CFX after giving effect to the Merger, as if it had  occurred
as  of the beginning  of each of  the periods presented,  after giving effect to
certain pro forma  adjustments: (i) using  an Exchange  Ratio of 1.7  as if  the
Merger  had  been accounted  for as  a pooling-of-interests;  and (ii)  using an
Exchange Ratio of 1.52 as  if the Merger had been  accounted for as a  purchase.
See  "PROPOSAL I --  PROPOSED MERGER --  Accounting Treatment." This information
should be read in  conjunction with the historical  financial statements of  CFX
and  Safety Fund, related notes and  other financial information incorporated by
reference herein or included  elsewhere in this Proxy  Statement. The pro  forma
consolidated  financial  statements  may  not  be  indicative  of  the financial
position or  results that  actually  would have  occurred  had the  Merger  been
consummated on the dates indicated, or which will be attained in the future. The
CFX  Trading Price is based on the CFX trading price on AMEX for the ten trading
days prior to receipt of the last regulatory approval necessary for consummation
of the Merger and thus could be determined several weeks prior to the  Effective
Time. The market price of CFX Common Stock at the Effective Time could therefore
differ  from the  CFX Trading  Price used to  determine the  Exchange Ratio. See
"AVAILABLE  INFORMATION;  DOCUMENTS  INCORPORATED  BY  REFERENCE,"  "PRO   FORMA
CONSOLIDATED  FINANCIAL INFORMATION  (UNAUDITED)," the  1995 Safety  Fund Annual
Report to Shareholders that  accompanies this Proxy Statement  and the 1995  CFX
Annual   Report  to   Shareholders  that   accompanies  this   Proxy  Statement.
Furthermore, there can be no assurance that  the CFX Trading Price will be  such
that  the Exchange Ratio would be  1.7 for a pooling-of-interests transaction or
1.52 for a purchase transaction or that  the exchange ratio would be 2.6446  for
the Milford Acquisition. See "PROPOSED MERGER -- Terms of the Merger."

of  and to  vote at  the Annual Meeting.  The holders  of each  of the 1,660,665
shares of  Safety Fund  Common Stock  outstanding  on the  Record Date  will  be
entitled  to one vote  for each share  held of record  upon each matter properly
submitted at the  Annual Meeting.  At such  date, there  were approximately  380
shareholders  of  record.  Under  Safety Fund's  Articles  of  Organization, the
presence, in person or by proxy, of the holders of a majority of the outstanding
shares of Safety Fund  Common Stock entitled  to vote at  the Annual Meeting  is
necessary  to constitute a quorum for the  transaction of business at the Annual
Meeting.
 
    Safety Fund believes and has been  advised by its counsel that, pursuant  to
its  Articles  of Organization  (and  consistent with  Massachusetts corporation
law), the Merger must be approved by  the affirmative vote of the holders of  at
least  a majority  of the  shares of  Safety Fund  Common Stock  outstanding and
entitled to vote thereon.  One of Safety Fund's  shareholders, David G.  Massad,
has informed Safety Fund through his counsel that he believes the Merger must be
approved by at least two-thirds of such shares. For information about the course
of  prior communications between Safety Fund  and Mr. Massad, see "-- Background
of the Merger." Safety Fund  has engaged the services  of a proxy solicitor  and
will attempt to obtain the votes of as many of its shareholders as is reasonably
practicable.   However,  Safety  Fund  and  CFX   intend  to  proceed  with  the
consummation of the Merger if the proposal  receives the approval of at least  a
majority  of  the shares  of  stock outstanding  and  entitled to  vote thereon,
assuming the other conditions to the closing are met or waived.
 
    The nominees for director  who receive the highest  number of votes cast  at
the Annual Meeting will be elected to serve on the Board. The appointment of the
auditors  of Safety Fund must be ratified by the affirmative vote of the holders
of a majority  of the  shares of  stock entitled  to vote  thereon, present  and
voting, assuming a quorum is present.
 
VOTING AND REVOCATION OF PROXIES
 
    Shares  of Safety Fund  Common Stock represented by  a proxy properly signed
and returned  will  be  voted at  the  Annual  Meeting in  accordance  with  the
instructions  thereon. If a proxy is  signed and returned without indicating any
voting instructions, the shares of Safety Fund Common Stock represented by  such
proxy  will be voted FOR approval of the Agreement, FOR election of the nominees
named herein as directors, FOR ratification of the appointment of Safety  Fund's
independent  auditors and, on other matters  presented for a vote, in accordance
with the judgment of the persons acting under the proxy.
 
    The presence of a shareholder at  the Annual Meeting will not  automatically
revoke such shareholder's proxy. However, shareholders may revoke a proxy at any
time  prior to its  exercise by filing with  the Clerk of  Safety Fund a written
notice of revocation, by delivering to Safety Fund a duly executed proxy bearing
a later date or by  attending the Annual Meeting  and voting in person.  Written
notices of revoked proxies may be directed to: John E. Howard, Clerk, The Safety
Fund Corporation, 470 Main Street, Fitchburg, MA 01420.
 
    Safety  Fund intends to count the shares of Safety Fund Common Stock present
in person at the Annual Meeting but not voting, and shares of Safety Fund Common
Stock for which it has  received proxies, but with  respect to which holders  of
shares  have  abstained on  any matter,  as  present at  the Annual  Meeting for
purposes of determining the presence or absence of a quorum for the  transaction
of  business. However, such nonvoting shares and abstentions will not be counted
as votes  cast  for purposes  of  determining  whether the  Agreement  has  been
approved and therefore will have the same
 
                                       23
<PAGE>
effect  as votes against the Agreement. In  addition, under the rules of the New
York Stock Exchange, brokers  who hold shares in  street name for customers  who
are  the beneficial owners of such shares  are prohibited from giving a proxy to
vote shares held for such  customers in favor of  the approval of the  Agreement
without  specific instructions from such  customers. Accordingly, the failure of
such customers to provide  instructions with respect to  their shares of  Safety
Fund  Common Stock to their broker will have the effect of such shares not being
voted and therefore will  have the same effect  as votes against the  Agreement.
Such instances, if any, are referred to as broker non-votes.
 
    The  Board of Directors of Safety Fund is not aware of any other business to
be acted upon at the  Annual Meeting other than as  described herein. It is  not
anticipated  that other matters  will be brought before  the Annual Meeting. If,
however, other  matters are  duly  brought before  the  Annual Meeting,  or  any
adjournment  thereof, the persons  appointed as proxies  will have discretion to
vote or  act thereon  according to  their best  judgment. The  persons named  as
proxies  by a shareholder may  propose and vote for  one or more adjournments or
postponements of the Annual Meeting to permit another solicitation of proxies in
favor of the Agreement. No proxy which is voted against the proposal to  approve
the Merger will be voted in favor of any such adjournment or postponement.
 
    In  connection with  the Merger,  each member of  the Board  of Directors of
Safety Fund has entered  into a Voting  Agreement to vote all  of the shares  of
Safety  Fund Common  Stock he is  entitled to  vote with respect  thereto at the
Annual Meeting  in favor  of  the Agreement,  not  including shares  which  such
director  holds in  a fiduciary  capacity. The number  of shares  of Safety Fund
Common Stock which such directors are entitled  to vote as of February 16,  1996
is  190,181, (11.45% of Safety Fund Common  Stock outstanding as of February 16,
1996). Additionally, each such  person 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 of Safety Fund  Common Stock prior  to
shareholder  approval of the Agreement or  termination of the Agreement pursuant
to the terms  thereof. Each such  person has also  agreed in his  capacity as  a
shareholder not to take any action that would substantially impair the prospects
of  completing the Merger pursuant to the Agreement. Assuming that directors and
executive officers of Safety  Fund and their  respective affiliates, holding  an
aggregate  of 196,234 shares of outstanding Safety Fund Common Stock (11.82%) as
of February  16,  1996,  vote  their  shares in  favor  of  the  Agreement,  the
affirmative vote of holders of approximately 634,099 additional shares of Safety
Fund Common Stock (38.18%) will be required in order for the Agreement to obtain
approval  by a majority of  the outstanding shares of  Safety Fund Common Stock.
See "-- Record Date; Voting Rights."
 
SOLICITATION OF PROXIES
 
    In addition to solicitation by mail, proxies may be solicited personally  or
by  telephone, and directors, officers and  employees of Safety Fund may solicit
proxies from the shareholders of Safety Fund without additional compensation  to
them and at nominal cost. Safety Fund has retained Morrow & Co. to assist in the
solicitation  of proxies. Safety Fund will pay Morrow  & Co. a fee of $4,000 for
its services, plus reimbursement for its out-of-pocket costs. Brokerage  houses,
nominees,  fiduciaries and other custodians have been requested to forward proxy
materials to beneficial owners  of Safety Fund Common  Stock and, upon  request,
will be reimbursed by Safety Fund for the expenses incurred by them. Safety Fund
will  bear the expenses  in connection with the  solicitation of proxies, except
that CFX and Safety  Fund will share the  expenses associated with the  printing
and  mailing of  this Proxy  Statement and  all filings  with the  Commission in
connection therewith.
 
                         PROPOSAL I -- PROPOSED MERGER
 
    This section  of  the Proxy  Statement  describes material  aspects  of  the
Merger.  The  following  description does  not  purport  to be  complete  and is
qualified in its entirety  by reference to the  Agreement, which is attached  as
Appendix  A to this Proxy Statement and is incorporated herein by reference. All
shareholders are urged to read the Agreement carefully and in its entirety.

BACKGROUND OF THE MERGER
 
    The Merger proposal is the culmination of a long process by Safety Fund  and
its  Board of Directors to maximize shareholder  value. Beginning in the Fall of
1993, the Board  of Directors  made significant  changes in  top management  and
began  formulating  a  new  financial plan.  In  February  1994,  Christopher W.
Bramley, a bank executive with experience  as a senior executive in the  Shawmut
Bank  organization, was hired to lead Safety  Fund. During the ensuing year, Mr.
Bramley hired a team  of executives who replaced  many members of Safety  Fund's
former  management. Management and the Board took  a number of steps designed to
redirect Safety Fund and put it on  stronger financial footing in the long  run.
Although  the steps taken by the Board  and management in 1993 and 1994 resulted
in a net loss of $3.1 million in  1993 and net income of only $158,048 in  1994,
the  Board believed  that these steps  were a  necessary prelude to  its goal of
rebuilding long-term shareholder value.
 
    By the beginning  of 1995, the  Board of Directors  felt that Safety  Fund's
financial  condition had  stabilized and  that Safety  Fund was  poised to begin
taking more affirmative steps to enhance  shareholder value. In March 1995,  the
Board voted to register Safety Fund Common Stock under the Exchange Act in order
to obtain the protections of the federal proxy and tender offer rules. The Board
also  adopted certain amendments  to Safety Fund's by-laws  which could have the
effect of  discouraging an  acquisition of  Safety Fund  or stock  purchases  in
furtherance  of an acquisition. These actions followed Safety Fund's receipt, in
January 1995, of  a Schedule  13D filing indicating  that one  of Safety  Fund's
shareholders,  David G. Massad,  had acquired approximately  6.7% of Safety Fund
Common Stock. Mr. Massad's Schedule 13D indicated that he might explore with the
management of Safety  Fund the possibility  of a business  combination or  other
transaction  between Safety Fund  and Commerce Bank  of Worcester, Massachusetts
("Commerce"). Commerce is a commercial bank with $179.2 million in assets as  of
September 30, 1995 that is more than 90% owned by Mr. Massad.
 
    In  order to better understand Mr. Massad's interest and intent with respect
to a Safety Fund/ Commerce combination, Safety Fund representatives met with Mr.
Massad on April 14, 1995, and met again  with an associate of Mr. Massad on  May
11,  1995. Although  Mr. Massad  did not  submit a  written proposal  for such a
combination, the Safety Fund representatives understood Mr. Massad's proposal to
be a business combination in which (i)  Safety Fund would acquire Commerce in  a
book  value for book  value exchange, (ii)  Mr. Massad would  be Chairman of the
Board and Mr. Bramley would  be President and (iii) a  majority of the board  of
directors of the ongoing entity would continue to be Safety Fund directors. Such
a  transaction would have had  the potential of Mr.  Massad's owning over 35% of
the combined entity. At the first  of those meetings, Mr. Massad also  expressed
his  opposition  to, and  said that  he intended  to campaign  publicly against,
certain amendments to Safety Fund's Articles of Organization which the Board had
proposed for  shareholder approval  at  the 1995  annual meeting  (the  proposed
amendments  would have conformed  Safety Fund's Articles  of Organization to the
1995 amendments to Safety Fund's by-laws and  were set forth and described in  a
proxy statement distributed to Safety Fund's shareholders in connection with the
1995 Annual Meeting). Subsequently, the Board determined that a contest over the
proposed  amendments would not be  in the best interests  of the Corporation and
decided not to pursue the proposed amendments.
 
    In light of the discussions with Mr.  Massad, at a meeting on May 22,  1995,
the  SFNB Board of Directors recommended  that the Directors' Advisory Committee
be re-established to review any proposals that might be received. The Committee,
consisting of  Messrs.  Condron, Grenon,  Heywood,  Kelly, Montuori,  Seder  and
Yates,  and Mr. Bramley  serving EX OFFICIO, met  immediately following the full
Board meeting.  The  Committee  discussed,  among  other  things,  the  business
combination  that had been suggested by Mr. Massad. The Committee concluded that
Safety Fund should seek the advice of outside advisors to guide the directors in
determining  the  actions  which  would  be   in  the  best  interests  of   the
shareholders.
 
                                       25
<PAGE>
    On  May 30, 1995,  the Directors' Advisory Committee  met to discuss further
the discussions with Mr. Massad as well as various other strategic  alternatives
available  to Safety  Fund, including  remaining independent  and combining with
another financial institution. At the meeting were Fredric Schluter, a financial
advisor whom  Safety Fund  was  considering engaging,  and a  representative  of
Foley,  Hoag  &  Eliot, Safety  Fund's  legal counsel.  The  Committee discussed
various  financial  and  legal   considerations  implicated  by  the   strategic
alternatives.  It was the sense  of the meeting that,  in order best to maximize
shareholder value, Safety Fund should  concentrate on continuing its  rebuilding
efforts before any further consideration could reasonably be given to sale to or
merger  with a  third party.  In July 1995,  the Company  engaged Mr. Schluter's
firm, MB&D, to serve as Safety Fund's financial advisor.
 
    The Directors'  Advisory Committee  met again  prior to  the full  Board  of
Directors' meeting on June 26, 1995 and further discussed, with counsel present,
the  discussions  with Mr.  Massad.  At the  full  Board meeting,  the Committee
reported to  the  Board  on  its  discussions  and  conclusions.  After  a  full
discussion,  the Board confirmed  the Committee's conclusion  that the terms Mr.
Massad and  his representatives  had outlined  for a  possible combination  with
Commerce were not attractive enough to pursue. Among the factors considered were
the  fact that, although the transaction would result in asset growth for Safety
Fund, the  Safety Fund  shareholders would  not receive  any premium  for  their
shares.  Instead, they would simply continue to own the stock of a merged entity
with a relatively  illiquid market for  its common stock  that would (after  the
merger)  be  dominated by  a single  controlling shareholder.  In coming  to its
conclusion, the  Board  noted  that  certain shareholders  with  whom  they  had
consulted had expressed no interest in such a transaction.
 
    Throughout  the  summer  and fall  of  1995,  the Board  and  the Directors'
Advisory Committee  continued to  focus  on various  steps consistent  with  its
decision  to remain independent and to  rebuild shareholder value. The Directors
focused on efforts to  improve Safety Fund's  financial condition and  earnings,
including the development of a new business plan. In addition, the Board and the
Committee  began to take  steps to improve  the liquidity of  Safety Fund Common
Stock and  to improve  the information  available to  shareholders. These  steps
included  listing Safety Fund Common Stock on the Nasdaq Stock Market, declaring
a stock  split, authorizing  the repurchase  of up  to $400,000  in Safety  Fund
Common  Stock and holding  a series of  informational meetings for shareholders.
The Board  also  adopted an  employee  severance plan.  Although  Safety  Fund's
energies  during this time were focused  on efforts to enhance shareholder value
as an independent company, the Board continued to investigate whether a business
combination with another financial institution might be in the best interests of
the shareholders.
 
    During this  time, Safety  Fund became  aware (through  a new  Schedule  13D
filing  in August) that Mr. Massad had acquired additional shares of Safety Fund
Common Stock, bringing  his aggregate  holdings to  9.9% of  Safety Fund  Common
Stock.  Mr. Massad's filing  indicated that he  remained interested in exploring
the possibility of a combination of Commerce  Bank and Safety Fund. In light  of
this  filing, representatives of the Directors'  Advisory Committee met with Mr.
Massad on September 1, 1995  with the goal of  learning more about Mr.  Massad's
ideas and plans for a possible combination with Commerce.
 
    From  that  meeting, the  Safety  Fund representatives  understood  that Mr.
Massad believed that a combined bank would  be stronger due to its larger  size,
but  that Mr. Massad had  not prepared any specific  business plans or pro forma
financial information  which  could demonstrate  that  a Commerce/  Safety  Fund
combination  would benefit the Safety Fund shareholders. They further understood
that Mr.  Massad planned  to  seek regulatory  approval to  purchase  additional
shares  of Safety Fund  Common Stock. The Directors'  Advisory Committee heard a
report about  the September  1 meeting  with Mr.  Massad at  the next  Committee
meeting  held on September  11, 1995. It was  the sense of  the meeting that Mr.
Massad had not added anything  to his proposal that  would cause them to  change
their  view that the proposed combination  between Safety Fund and Commerce Bank
would not be in the best interests of the Safety Fund shareholders.
 
                                       26
<PAGE>
    At a meeting on  September 26, 1995, the  SFNB Board of Directors  concluded
that   Mr.  Bramley  should  enter   into  preliminary  discussions  with  other
institutions that might  be interested in  combining with Safety  Fund on  terms
attractive  to the shareholders. At  its next meeting held  on October 23, 1995,
the Safety  Fund  Board  confirmed  the  direction  to  management  to  initiate
exploratory  discussions with selected potential  strategic partners in order to
assess more clearly the options available to Safety Fund and the possible  value
that might be realized for the shareholders.
 
    Following  the Board's direction, Mr. Bramley held meetings with a number of
financial institutions to  assess potential interest,  including a meeting  with
CFX on October 3, 1995. Mr. Bramley with the assistance of MB&D identified three
financial institutions (one of which was CFX, which had independently approached
Safety  Fund in  early 1995)  as the  most attractive  potential partners. These
three institutions were  selected by  applying two  criteria: the  institutions'
apparently  strong  strategic  need to  establish  a foothold  in  Safety Fund's
market, and  their apparent  financial capacity  to maximize  value for  all  of
Safety   Fund's  constituencies.  Based  upon   preliminary  inquiries,  it  was
determined that two of the three  institutions were interested in considering  a
merger with Safety Fund.
 
    At a meeting held on November 8, 1995, the Board of Directors again met with
Safety Fund's legal counsel and financial advisor, who made presentations to the
Board  outlining  the  various factors  to  be  considered by  the  directors in
evaluating certain strategic  alternatives, including  remaining an  independent
entity, combining with one or more business partners, or auctioning Safety Fund,
and  the advantages  and drawbacks of  each course. After  the presentations and
lengthy discussions, including questions to the Safety Fund advisors, the  Board
of  Directors voted that it intended to remain independent in order to implement
the business plan  and other  initiatives the  Board had  undertaken to  improve
shareholder value during the summer of 1995 and to fulfill Safety Fund's mission
statement, including the mission of being the premier, independent local bank in
central Massachusetts. However, the Board felt that it was prudent to retain the
flexibility to continue to pursue potential strategic partners.
 
    In  late November  1995, Safety  Fund learned  that Mr.  Massad had  filed a
regulatory application for approval to purchase up to 51% of Safety Fund  Common
Stock.  Mr. Massad's filing  indicated (among other things)  that he intended to
consider using any and all legal means to purchase additional shares (up to 51%)
of Safety  Fund  Common Stock,  including  open market  transactions,  privately
negotiated transactions and one or more tender offers.
 
    The Directors' Advisory Committee met on December 4, 1995 with Safety Fund's
legal  counsel and  its financial  advisor to  discuss Safety  Fund's options in
light of Mr. Massad's regulatory filing  and to hear presentations from the  two
financial  institutions which had  been identified as  attractive and interested
candidates for a  strategic combination.  The Committee  discussed Mr.  Massad's
regulatory  filing, and felt that  the interests of the  shareholders as a whole
would not be  served by a  single shareholder acquiring  a controlling  interest
(but not all) of Safety Fund Common Stock. The Committee concluded that it would
be  desirable  to  schedule  another  meeting with  Mr.  Massad  to  discuss his
regulatory filing and  to determine  whether he had  any interest  in making  an
offer to purchase Safety Fund as a whole.
 
    At the December 4 meeting, the Committee also received a presentation by its
financial  advisor about the two financial institutions that had been invited to
make   presentations   to   the   Committee.   Following   that    presentation,
representatives  of the two financial institutions made successive presentations
to the Committee. The purpose of these presentations was to enable the Committee
to learn about  the history,  financial performance and  banking philosophy  and
strategies  of these two companies, and to  determine whether or not Safety Fund
should move to the next step in pursuing a possible merger with either of  them.
After  hearing  those  presentations,  the  Committee  determined  that  written
nonbinding expressions of interest should be solicited from both institutions.
 
    On December 13, 1995, representatives  of the Directors' Advisory  Committee
(including  a representative of  MB&D) met with  Mr. Massad and  an associate as
requested by the  Committee. At  that meeting, the  Safety Fund  representatives
told    Mr.   Massad   that    they   thought   it    would   be   inappropriate
 
                                       27
<PAGE>
from  the  perspective  of  Safety  Fund's  other  shareholders  for  a   single
shareholder  to own 51% of Safety Fund  Common Stock (as Mr. Massad had proposed
through his regulatory filing). The  Safety Fund representatives understood  Mr.
Massad's position to be that he did not plan to make a proposal to purchase 100%
of Safety Fund Common Stock, and in fact he did not make such a proposal.
 
    The full Board of Directors met again on December 18, 1995. At that meeting,
the  Committee reported to the Board on the meetings the Committee had held with
the two financial institutions and with Mr. Massad. Both financial  institutions
had  submitted  nonbinding expressions  of interest  to  acquire Safety  Fund. A
representative  of  MB&D  made  a  presentation  to  the  Board  about  the  two
expressions  of interest, both  of which were  stock-for-stock merger proposals.
For a number of  reasons, the CFX  proposal was more  attractive than the  other
proposal, including the apparently greater strategic fit and the higher value of
the  consideration  offered  by CFX,  based  on  the market  prices  of  the two
offerors' stock at that time.
 
    It was important  to the  Board that  the transaction  have two  alternative
accounting structures (and that the closing of the transaction not be contingent
upon the availability of the pooling method of accounting), because facts beyond
Safety  Fund's control could dictate which accounting method must be applied. In
particular, if Safety  Fund shareholders holding  more than ten  percent of  the
Safety  Fund  Common  Stock exercise  their  dissenters' rights,  the  Merger is
required to be accounted for  with purchase accounting under generally  accepted
accounting  principles. At the  time the Merger  Agreement was being negotiated,
Mr. Massad owned 9.9 percent of the Safety Fund Common Stock and had applied for
regulatory approval to purchase up to  51 percent of such stock (which  approval
was  received on  January 19, 1996).  The Board authorized  management to pursue
negotiations with CFX, but  to make it clear  that the transaction must  include
both  purchase accounting and  pooling-of-interests accounting alternatives. The
Board also directed  management to  maintain contact with  the other  interested
party.  MB&D promptly informed  the other party that  Safety Fund was commencing
negotiations with another (unnamed)  party, that Safety  Fund felt it  necessary
for  any bidder to offer a purchase  accounting alternative and that Safety Fund
would still consider expressions of interest from the other party.
 
    On December 21,  1995, Safety  Fund and CFX  and their  legal and  financial
advisors  met to commence negotiations with respect to the definitive Agreement.
During Christmas week, each of Safety Fund and CFX conducted due diligence  with
respect to the other's financial condition and other relevant matters, and their
counsel  continued to  refine the  terms of the  Agreement. On  January 1, 1996,
Safety Fund representatives met with Safety Fund's legal and financial  advisors
to  discuss the status of the due diligence and the Agreement. On January 2, the
parties and  their advisors  met again  to continue  to negotiate  the  proposed
Agreement.
 
    The  Board of Directors held a special meeting on January 3, 1996 to discuss
the due diligence results  and the negotiation process  and to review copies  of
the  draft Agreement, Stock  Option Agreement and  related documents with Safety
Fund's legal and financial advisors. At that meeting, counsel reviewed in detail
with the directors the  terms of the Agreement  and the Stock Option  Agreement.
The  Board also  heard a detailed  presentation by MB&D  regarding the financial
terms of  the Merger,  and held  a  detailed discussion  of the  exchange  ratio
formula  and the alternative  pooling and purchase  accounting structures. After
several hours of discussion, the  Board authorized management and the  Committee
to move forward with the CFX transaction, subject to the Board's approval of the
final Agreement at a subsequent meeting.
 
    The  Board of Directors met  again on January 5,  1996. At that meeting, the
Board reviewed  with counsel  those  changes that  had  been negotiated  to  the
Agreement  since the January 3 meeting, and discussed the Stock Option Agreement
in detail. At that  meeting, a representative of  MB&D advised the Board  orally
that, in the opinion of MB&D, and based on facts known to MB&D at that date, the
Exchange  Ratio was  fair, from a  financial point  of view, to  the Safety Fund
shareholders as of that date. He also stated that, absent significant change  in
the  two companies' financial condition  or in the market  for their stock, MB&D
anticipated that  it  would be  prepared  to  issue a  similar  written  opinion
 
                                       28
<PAGE>
as  of the date of  the proxy statement to  shareholders. The Board of Directors
voted to approve the  Agreement and the Stock  Option Agreement at that  meeting
and also voted to adopt the Shareholder Rights Plan previously considered.
 
REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Safety Fund Board's decision to approve and adopt the Agreement reflects
its belief that the terms of the Agreement will provide significant value to all
Safety  Fund  shareholders  and will  also  enable  them to  participate  in the
opportunities for growth that  the Safety Fund Board  believes the Merger  makes
possible.  In the course of reaching its  decision to approve the Agreement, the
Board of Directors of Safety Fund consulted with Safety Fund management as  well
as  with  Safety  Fund's legal  and  financial advisors.  Without  assigning any
relative or  specific weights  thereto, the  Board of  Directors considered  the
factors  outlined below, among others, that it believed relevant to reaching its
determination.
 
    The terms of the  Agreement, including the Exchange  Ratio, were reached  on
the  basis of arms' length negotiations between Safety Fund and CFX. In reaching
the conclusion that the terms of the Agreement are fair, the Board of  Directors
considered, among other things, the market value, book value, earnings per share
and  dividends of Safety Fund Common Stock. The Board considered that the Merger
provides an  opportunity for  the  shareholders of  Safety  Fund to  receive  an
increase  in dividends  and to receive  consideration for their  shares having a
value in excess of the book value of the Safety Fund Common Stock and, based  on
the estimated value of the Merger consideration, at a premium over the prices at
which Safety Fund Common Stock has generally traded in the recent past.
 
    The  Board  of  Directors relied  upon  the  advice of  MB&D,  Safety Fund's
financial advisor. At the January 5, 1996 Safety Fund Board meeting, MB&D orally
rendered its opinion  that, based upon  information known as  of that date,  the
merger consideration is fair, from a financial point of view, to the Safety Fund
shareholders.  That opinion was rendered in writing as of the date of this Proxy
Statement. A  copy  of  the  written  opinion, dated  the  date  of  this  Proxy
Statement,  rendered by MB&D to the Board of Directors is attached as Appendix C
to this  Proxy  Statement.  Safety  Fund's Board  of  Directors  considered  the
analyses presented to it by MB&D relating to selected financial and stock market
data  concerning Safety Fund and CFX, certain financial analyses of the terms of
the Merger, including a  discounted cash flow analysis  and a comparison to  the
terms  of other recent acquisitions, which are described below under "-- Opinion
of Financial Advisor."
 
    The Board of  Directors considered the  strategic alternatives available  to
Safety Fund, including the possibility of remaining independent, seeking further
to solicit competing proposals from other potential bidders, and accepting CFX's
bid, before concluding for the reasons discussed in this section that the Merger
represented  the best available alternative to enhance shareholder value at this
time.
 
    In assessing the  alternatives for  remaining independent,  the Safety  Fund
Board  considered the long-range  prospects and risks  of Safety Fund's business
and its  financial  condition, results  of  operations and  capital  levels.  In
assessing  the long-range  prospects and  risks of  Safety Fund's  business, the
Safety Fund  Board considered:  (i)  the risk  that the  assumptions  underlying
Safety  Fund's business plan, such as assumptions about the future interest rate
environment, might not be realized; (ii) the risks associated with attempting to
achieve and sustain significant loan growth; and (iii) the fact that the banking
market in Worcester County is becoming increasingly competitive, particularly in
light of the pending entrance into the market of two out-of-state banks.
 
    The Board of Directors also considered  the possibility that, if it were  to
remain  independent, a  significant portion  of Safety  Fund Common  Stock could
become concentrated  in  the  hands  of a  single  shareholder  who  had  sought
regulatory  approval to acquire up to 51% of Safety Fund Common Stock. The Board
felt that such a concentration could make it more difficult for the Board to act
in a manner that it believes to be in the best interests of the shareholders  as
a whole.
 
    The  Board also considered the process  that was used to solicit indications
of interest on the part of potential acquirors of Safety Fund and believes  that
it was appropriate.
 
                                       29
<PAGE>
    The  Board  of Directors  considered the  advantages of  becoming part  of a
larger financial institution that has  considerably greater resources and  whose
stock  is traded on the AMEX. Safety Fund's Board of Directors believes that the
proposed  affiliation  with  CFX  could  provide  increased  liquidity  for  the
shareholders  of Safety Fund.  The Board also believes  that such an affiliation
could lead  to  competitive  advantages through  greater  diversity  in  product
offerings,  cost-savings through  integration of operations,  improved access to
capital and funding, and geographic expansion of operations.
 
    The Board of Directors  considered the historical  growth in CFX's  earnings
per  share and book value. The Board of Directors also considered the historical
dividends paid on Safety Fund Common  Stock and CFX Common Stock,  respectively,
and  the significant increase in dividends  which Safety Fund shareholders would
be likely  to enjoy  as a  result of  the Merger.  The Board  of Directors  also
considered the expectation that the Merger will be a tax-free reorganization.
 
    The  Board of Directors considered a  variety of factors, including, without
limitation, the  social and  economic effects  of a  transaction on  depositors,
borrowers  and employees of Safety Fund, and  on the communities in which Safety
Fund operates or  serves. Massachusetts  law permits  the Safety  Fund Board  to
consider  these  factors at  least to  the extent  there are  rationally related
benefits accruing  to shareholders.  The Board  of Directors  believes that  the
Merger,  if consummated, will provide expanded services, greater ability to grow
and diversify, and access to the resources of a strong financial parent. If  the
Safety Fund shareholders do not approve and adopt the Agreement or the Agreement
is  not consummated  for any  other reason,  the Board  of Directors  expects to
continue to operate Safety Fund as an ongoing business.
 
    Based on the foregoing,  the Safety Fund Board  concluded that the  proposed
Merger  would be in the best  interests of Safety Fund's shareholders, customers
and communities served. Accordingly, the Safety Fund Board unanimously voted  to
recommend that the Safety Fund shareholders vote "FOR" the approval and adoption
of the Agreement.
 
TERMS OF THE MERGER
 
    In  accordance with the terms of the Agreement, a wholly owned subsidiary of
CFX organized for the  purpose will be  merged with and  into Safety Fund,  with
Safety  Fund as the  surviving corporation. Immediately  thereafter, Safety Fund
will be merged  with and into  CFX, whereupon the  separate existence of  Safety
Fund  will  cease. CFX,  as  the surviving  entity  in these  transactions, will
continue unaffected and unimpaired by such transactions.
 
    At the Effective  Time, each share  of Safety Fund  Common Stock issued  and
outstanding  immediately  prior to  the  Effective Time,  other  than Dissenting
Shares and except as otherwise provided in the Agreement, will be converted into
an amount of CFX Common Stock equal  to one share multiplied by the  appropriate
Exchange Ratio and cash in lieu of any fractional share of CFX Common Stock.
 
    The  Exchange Ratio  depends on two  principal factors. The  first factor is
whether a Pooling  Determination has  been made. The  second factor  is the  CFX
Trading Price. See "INTRODUCTION." At any given price level of CFX Common Stock,
the number of shares of CFX Common Stock to be received for each share of Safety
Fund  Common Stock (and thus  the per share value to  be received by Safety Fund
shareholders)  will  be  less   under  a  purchase   accounting  than  under   a
pooling-of-interests  accounting. See the graphs depicting the pricing mechanism
in "SUMMARY  -- The  Proposed Merger."  The exercise  of dissenters'  rights  by
holders  of  ten percent  or more  of  Safety Fund  Common Stock  would preclude
pooling treatment.
 
    The following tables show the Exchange  Ratio at various CFX Trading  Prices
if  a Pooling Determination is made or is not made, together with the Per Safety
Fund Share Value in each case. As  used herein, the Per Safety Fund Share  Value
is  calculated by multiplying  the CFX Trading Price  by the applicable Exchange
Ratio, and represents the  value of a  share of CFX Common  Stock that would  be
received  in the Merger for each share of  Safety Fund Common Stock based on the
CFX Trading Price. The CFX  Trading Price is based on  the CFX trading price  on
AMEX  for the ten trading days prior  to receipt of the last regulatory approval
necessary for consummation of the Merger and thus
 
                                       30
<PAGE>
could be determined several weeks prior to the Effective Time. The market  price
of  CFX Common  Stock at the  Effective Time  could differ from  the CFX Trading
Price used to determine the Exchange Ratio,  and the actual value of the  shares
issued  in the  Merger therefore  could differ  from the  Per Safety  Fund Share
Value.

(1) If a Pooling Determination is  made, Safety Fund by  action of its Board  of

    Agreement, the Exchange Ratio would be  1.806 and the Per Safety Fund  Share
    Value  would be  less than  $21.06. If  Safety Fund  seeks to  terminate the
    Agreement, CFX may  adjust the Exchange  Ratio to the  amount determined  by
    dividing  $21.06 by the  CFX Trading Price  (resulting in a  Per Safety Fund
    Share Value of $21.06)  and the Merger would  be consummated on that  basis.
    Alternatively, CFX could do nothing in response, in which case the Agreement
    would terminate.

(1) If  a Pooling Determination is not made,  Safety Fund by action of its Board
    of Directors may, but need not, seek  to terminate the Agreement if the  CFX
    Trading Price is below $12.50. If Safety Fund does not seek to terminate the
    Agreement,  the Exchange Ratio would be 1.600  and the Per Safety Fund Share
    Value would  be less  than $20.00.  If Safety  Fund seeks  to terminate  the
    Agreement,  CFX may  adjust the Exchange  Ratio to the  amount determined by
    dividing $20.00 by the CFX Trading Price or make an additional cash  payment
    (in  either case resulting in  a Per Safety Fund  Share Value of $20.00) and
    the Merger would be consummated on  that basis. Alternatively, CFX could  do
    nothing in response, in which case the Agreement would terminate.
 
    Any  cash payment in lieu of fractional shares will be in an amount equal to
such fraction multiplied by the reported closing sale price of CFX Common  Stock
on  the  AMEX  as  reported in  THE  WALL  STREET JOURNAL  for  the  trading day
immediately preceding the date of the Effective Time.
 
    Safety Fund  has adopted  a 1984  Incentive  Stock Option  Plan and  a  1994
Incentive  and Nonqualified Stock Option  Plan (collectively, "Safety Fund Stock
Option Plans"). At the Effective Time, outstanding obligations under the  Safety
Fund  Stock Option Plans will  be assumed by CFX and,  except as provided in the
Agreement, each  stock option  outstanding under  the Safety  Fund Stock  Option
Plans  will become the right to receive,  upon payment of the exercise price, as
adjusted by the Exchange Ratio, a number of shares of CFX Common Stock equal  to
the  Exchange Ratio  multiplied by  the number of  shares of  Safety Fund Common
Stock covered by such options, rounded down to the
 
                                       31

nearest share. As  of March 28,  1996, there were  outstanding under the  Safety
Fund  Stock Option Plans  options held by  eight present and  former officers of
Safety Fund to acquire an aggregate of 50,850 shares of Safety Fund Common Stock
at an exercise  price ranging from  $10.33 per  share to $12.67  per share.  For
additional  information,  see  "PROPOSAL  I  --  PROPOSED  MERGER  --  Effect on
Employees and  Benefit  Plans" and  PROPOSAL  II  -- ELECTION  OF  DIRECTORS  --
Executive Compensation and Other Information."
 
    In  the event that, prior  to the Effective Time,  the outstanding shares of
CFX Common Stock shall have been increased, decreased, changed into or exchanged
for a different number of  shares or securities as  a result of a  distribution,
stock  dividend,  stock  split  or  stock combination  in  CFX  Common  Stock or
securities  convertible  into  CFX  Common  Stock,  all  without  CFX  receiving
consideration  therefor, then an appropriate  and proportionate adjustment shall
be made to the Exchange Ratio.
 
OPINION OF THE FINANCIAL ADVISOR
 
    MB&D has delivered  to the  Board of Directors  of Safety  Fund its  written
opinion  as  of  the date  of  this  Proxy Statement,  that  the  Exchange Ratio
(described in detail in this Proxy Statement) is fair, from a financial point of
view, to Safety  Fund's shareholders.  MB&D has  acted as  financial advisor  to
Safety  Fund since July 1995 in  connection with Safety Fund's ongoing strategic
planning process, including the evaluation of strategic and business plans,  the
evaluation  of hypothetical affiliation  opportunities and a  variety of general
corporate finance issues.
 
    MB&D advised Safety Fund  during the negotiation process  leading up to  the
execution  of the Agreement and provided Safety Fund with various analyses as to
the range of financially  feasible exchange ratios that  might be received in  a
hypothetical  transaction. Representatives of MB&D attended a number of meetings
of the Directors' Advisory Committee (which acted as the mergers and acquisition
committee) of the Safety Fund Board of Directors and met with the full Board  of
Directors  on several occasions in connection  with the preparation and analysis
of Safety Fund's  strategy. The Exchange  Ratio was arrived  at in  consultation
with  MB&D as to the terms of  arms' length negotiations between Safety Fund and
CFX.
 
    MB&D was  retained  based  on  its  qualifications  and  experience  in  the
financial analysis of financial institutions, knowledge of the banking market of
the  Northeast  United  States  and  of  Massachusetts  in  particular,  and its
experience  with  merger  and   acquisition  transactions  involving   financial
institutions.  Members of the Corporate Finance  Department of MB&D have advised
financial institution clients on more than 50 successfully completed mergers  or
acquisitions of financial institutions.
 
    The  full text of  the opinion of  MB&D, which sets  forth assumptions made,
matters considered and  limits on  the review  undertaken by  MB&D, is  attached
hereto  as Appendix C. Safety Fund's shareholders  are urged to read the opinion
in its entirety. MB&D's opinion is directed only to the Exchange Ratio and  does
not  constitute a recommendation to any holder of Safety Fund Common Stock as to
how such holder should vote at the Annual Meeting. The summary of the opinion of
MB&D set forth in this Proxy Statement  was provided to Safety Fund by MB&D  and
is  qualified  in its  entirety by  reference to  the full  text of  the opinion
itself.
 
    In arriving at its opinion, MB&D  (i) reviewed the Agreement and this  Proxy
Statement in substantially the form to be sent to Safety Fund shareholders; (ii)
reviewed  publicly available business and  financial information with respect to
both Safety  Fund  and  CFX  and  certain  internal  financial  information  and
financial  projections prepared by the managements of Safety Fund and CFX; (iii)
held discussions with members of the senior management and Board of Safety  Fund
concerning  the  past and  current  results of  operations  of Safety  Fund, its
current financial condition  and management's opinion  of its future  prospects;
(iv)  reviewed the  historical reported price  and record of  trading volume for
both Safety Fund Common  Stock and CFX Common  Stock; (v) held discussions  with
the  senior  management  of  CFX  concerning the  current  and  past  results of
operations of CFX, its current  financial condition and management's opinion  of
its future prospects; (vi) considered the current state
 
                                       32
<PAGE>
of  and future  prospects for the  economies of Massachusetts  and New Hampshire
generally and the relevant market areas  for Safety Fund and CFX in  particular;
(vii)  reviewed the  specific acquisition  analysis models  employed by  MB&D to
evaluate potential business combinations  of banking companies; (viii)  reviewed
the  reported financial  terms of  certain recent  business combinations  in the
banking industry; and  (ix) performed such  other studies and  analyses as  MB&D
considered  appropriate under the circumstances  associated with this particular
transaction.
 
    MB&D's opinion takes into account its assessment of general economic, market
and financial conditions and  its experience in other  transactions, as well  as
its experience in securities valuation and its knowledge of the banking industry
generally.  For purposes  of reaching its  opinion, MB&D has  assumed and relied
upon the accuracy and completeness of  the information provided to it by  Safety
Fund  and  CFX,  and does  not  assume  any responsibility  for  the independent
verification of  such information.  Further, MB&D  has not  received from  third
parties,  nor prepared,  any independent  valuation or  appraisal of  any of the
assets or  liabilities  of  either Safety  Fund  or  CFX. With  respect  to  the
financial  projections reviewed by MB&D in  the course of rendering its opinion,
MB&D has assumed that such projections have been reasonably prepared to  reflect
the best currently available estimates and judgment of the management of each of
Safety Fund and CFX as to the most likely future performance of their respective
companies.
 
    MB&D  also considered the results of its efforts (at the direction of Safety
Fund) to solicit expressions of interest  from third parties with respect to  an
affiliation  with Safety Fund and  its review and analysis  of the terms of such
expressions. See "-- Background of the Merger."
 
    The following  is  a  summary  of material  analyses  employed  by  MB&D  in
connection  with rendering its written  opinion. Given that it  is a summary, it
does not  purport to  be a  complete and  comprehensive description  of all  the
analyses  performed, or an enumeration of all  the matters considered by MB&D in
arriving at its opinion. The preparation of a fairness opinion is a  complicated
process,  involving  a determination  as to  the  most appropriate  and relevant
methods of  financial analysis  and  the application  of  those methods  to  the
particular  circumstances. Therefore, such an opinion is not readily susceptible
to a summary  description. In  arriving at its  fairness opinion,  MB&D did  not
attribute  any  particular  weight  to  any  one  specific  analysis  or  factor
considered by it and  made qualitative as well  as quantitative judgments as  to
the  significance of each analysis and  factor. Consequently, MB&D believes that
its analyses must  be considered  as a whole  and feels  that attributing  undue
weight  to any single analysis or factor considered could create a misleading or
incomplete view of the process leading to  the formation of its opinion. In  its
analyses,  MB&D has  made certain assumptions  with respect  to banking industry
performance, general business and economic conditions and other factors, many of
which are beyond the  control of management  of either Safety  Fund or CFX.  Any
estimates  which  are  referred  to  in  MB&D's  analyses  are  not  necessarily
indicative of actual values or predictive of future results or values, which may
vary significantly from those set forth.
 
    ANALYSIS OF THE  ANTICIPATED MERGER AND  THE EXCHANGE RATIO  IN RELATION  TO
CFX.   The consideration to be paid in the Merger, assuming an Exchange Ratio of
1.7 shares of CFX Common Stock for each  share of Safety Fund Common Stock in  a
pooling-of-interests  accounting  transaction  or  1.52  shares  in  a  purchase
accounting transaction, valued  at the  last sale  price of  Safety Fund  Common
Stock  ($23.25)  on January  3,  1996, the  last day  with  trades prior  to the
announcement of the  transaction, and the  last sale price  of CFX Common  Stock
($15.375)  on  January  4,  1996,  the day  prior  to  the  announcement  of the
transaction, represents the following transaction multiples:
 
    POOLING ACCOUNTING TRANSACTION VALUE: $26.14 PER SAFETY FUND SHARE VALUE:
 
    - MULTIPLE OF EARNINGS:  (i)  26.02 times Safety Fund's annualized  earnings
      per  share for the nine months ended  September 30, 1995; (ii) 27.23 times
      Safety Fund's  recorded earnings  per share  for the  twelve months  ended
      September 30, 1995; (iii) 23.34 times Safety Fund's earnings per share for
      1995;  and (iv) 14.09 times Safety Fund's estimated earnings per share for
      1996.
 
    - MULTIPLE OF BOOK VALUE:  (i) 2.18 times Safety Fund's tangible book  value
      per  share as  of September  30, 1995; and  (ii) 2.03  times Safety Fund's
      tangible book value per share as of December 31, 1995.
 
                                       33
<PAGE>
    - MULTIPLE OF MARKET  VALUE:   (i) a  12% premium  over the  sales price  of
      Safety  Fund Common Stock  reported on the  Nasdaq Stock Market  as of the
      close of business on January 3, 1996; (ii) a 54% premium over the  average
      sales  price of Safety Fund Common Stock for the period January 5, 1995 to
      January 5, 1996; and (iii) a 34%  premium over the average sales price  of
      Safety Fund Common Stock for the third quarter of 1995.
 
    PURCHASE ACCOUNTING TRANSACTION VALUE: $23.37 PER SAFETY FUND SHARE VALUE:
 
    - MULTIPLE  OF EARNINGS:  (i) 23.27  times Safety Fund's annualized earnings
      per share for the nine months  ended September 30, 1995; (ii) 24.34  times
      Safety  Fund's recorded  earnings per  share for  the twelve  months ended
      September 30,  1995; (iii)  20.87 times  Safety Fund's  1995 earnings  per
      share; and (iv) 12.60 times Safety Fund's estimated earnings per share for
      1996.
 
    - MULTIPLE  OF BOOK VALUE:  (i) 1.94 times Safety Fund's tangible book value
      per share as of September 30, 1995; and (ii) 1.81 times Safety Fund's book
      value per share as of December 31, 1995.
 
    - MULTIPLE OF MARKET VALUE:  (i) a 1% premium over the sales price of Safety
      Fund Common Stock reported on the Nasdaq  Stock Market as of the close  of
      business  on January 3,  1996; (ii) a  49% premium over  the average sales
      price of  Safety Fund  Common Stock  for  the period  January 5,  1995  to
      January  5, 1996; and (iii) a 29%  premium over the average sales price of
      Safety Fund Common Stock for the third quarter of 1995.
 
    SPECIFIC ACQUISITION  ANALYSIS.    MB&D  employs  a  number  of  proprietary
analysis  models to  examine hypothetical transactions  involving banking and/or
thrift companies. The models use forecast earnings data, selected current period
balance sheet and income statement data, current market and trading  information
and a number of assumptions as to interest rates for borrowed funds, opportunity
costs  of  funds,  discount rates,  dividend  streams, effective  tax  rates and
transaction structures (the alternative or combined uses of common equity, cash,
debt or other securities, to fund a transaction). The models distinguish between
purchase and pooling accounting treatments and inquire into the likely  economic
feasibility  of  a given  hypothetical transaction,  at a  given price  level or
specified exchange rate  and employing  a specified  transaction structure.  The
model also permits an examination of pro forma capital adequacy.
 
    In  connection with the Merger, MB&D evaluated two floating exchange ratios,
the first being  1.7 (subject to  certain adjustments) in  an all common  stock,
pooling  accounting transaction  and the second  being 1.52  (subject to certain
adjustments) in  an all  common stock,  purchase accounting  transaction.  After
considering the potential for the realization of expense savings expected by CFX
to  result from  the consolidation of  selected operational  functions of Safety
Fund and  CFX,  estimated to  be  20%  of historical  Safety  Fund  non-interest
expense,  little or no ongoing earnings dilution is projected to result from the
contemplated transaction.
 
    DISCOUNTED CASH FLOW ANALYSIS.  MB&D also performed two discounted cash flow
analyses to permit the conceptual  examination of the present discounted  values
of potential future results employing selected assumptions and discount rates.
 
    In  the  first  discounted  cash  flow  analysis,  MB&D  discussed  with the
management of Safety Fund a projection of hypothetical Safety Fund earnings  per
share results for calendar years 1996 and 1997 of $1.85 and $2.06, respectively,
with  subsequent earnings  equal to  a return  on assets  ("ROA") of  1.05%, and
employed a hypothetical dividend pay-out ratio assumption which depicted average
annual pay-outs of 30%. MB&D then  assumed that the control sale  price/earnings
ratio  at the end of  a five-year period would  approximate 12.0 times earnings.
Given the five-year time horizon and a discount rate of 12.5%, this resulted  in
a  present discounted value of  the resulting cash flows  of $22.32 which can be
compared to the nominal  present value of  the 1.7 and  1.52 Exchange Ratios  of
approximately $26.14 and $23.37 described above.
 
                                       34
<PAGE>
    In  the  second discounted  cash flow  analysis,  MB&D employed  an earnings
annuity concept in which it assumed  that future earnings for Safety Fund  would
equal  a 1.00% ROA in  the twelve months subsequent to  September 30, 1995 and a
1.05% ROA annually  for the  four following years,  with asset  growth equal  to
4.47%  in the twelve months subsequent to  September 30, 1995 and 6.00% annually
for the four following years, and that the dividend pay-out ratio would increase
from 14% to 30% in  the first two years and  thereafter remain constant at  30%.
MB&D employed a discount rate for all cash flows of 12.5% and a long term growth
rate  of earnings in years  six and beyond of  5.00% annually. Given a five-year
time horizon, this resulted in a present discounted value of the resulting  cash
flows  of $19.47, which can be compared to  the nominal present value of the 1.7
and 1.52 Exchange Ratios of approximately $26.14 and $23.37 described above.
 
    MB&D considers it  is important  that the discount  factors employed  embody
both the concept of a riskless time value of money and risk factors that reflect
the   uncertainty  of  the  forecast  cash  flows  and  terminal  price/earnings
multiples. Use of higher discount rates would result in lower discounted present
values and vice  versa. MB&D  advised the Safety  Fund Board  of Directors  that
although   the  discounted  cash  flow  analysis  is  a  widely  used  valuation
methodology, it  relies  on  numerous  assumptions,  including  discount  rates,
terminal values, earnings and asset growth, as well as dividend payout ratios.
 
    MB&D  also  considered  that Safety  Fund  shareholders  would substantially
increase their prospect for  annual dividends based  upon current and  projected
dividend  streams of both Safety Fund and CFX. Based upon the dividend currently
paid by CFX, Safety Fund shareholders  would receive an equivalent dividend  per
share  of Safety Fund Common Stock of $1.22 per year (assuming an Exchange Ratio
of 1.7). Assuming  an Exchange  Ratio of  1.52, Safety  Fund shareholders  would
receive  an annual dividend of $1.09. By  comparison, Safety Fund has not paid a
Safety Fund Common Stock dividend since August 31, 1993.
 
    ANALYSIS OF  OTHER COMPARABLE  TRANSACTIONS.   MB&D  is reluctant  to  place
excessive  emphasis on "comparables analysis" as  a valuation methodology due to
what it considers to be inherent  limitations of the application of the  results
to  specific  cases. It  has observed  that  such analysis  as employed  by some
industry observers and  financial advisors frequently  fails to adequately  take
into  consideration  such  factors  as material  differences  in  the underlying
capitalization  of  the  comparable  institutions  which  are  being   acquired;
differences in the historic earnings (or loss) patterns recorded by the compared
institutions which are being acquired; different trends than might be implied by
examining  only recent financial results; failure to exclude nonrecurring profit
or loss items from the last twelve months' earnings streams of target companies,
which can distort apparent earnings multiples; differences in the form or  forms
of  consideration  used to  complete  the transaction;  differences  between the
planned method  of  accounting for  the  completed transaction;  and  such  less
accessible  factors  as the  relative  population demographics  of  the acquired
entities' markets as compared or contrasted  to such factors for the markets  in
which  comparables are doing business. Comparables analysis also rarely seems to
take into consideration the degree of facilities overlap between the  acquiror's
market  and that of the target or the  absence of such overlap and the resulting
cost  savings  differentials   between  two   otherwise  apparently   comparable
transactions.  MB&D  consequently  believes that  comparables  analysis  has its
limitations.
 
    Nevertheless, in November and December 1995, MB&D reviewed a universe of  27
publicly  announced transactions in the financial institutions industry in which
either a bank or a thrift (or their respective holding companies) engaged in the
acquisition of another financial institution. These transactions were  announced
between  January  1994  and  December 1995.  All  of  the  examined transactions
involved entities  doing  business in  New  England. From  this  universe,  MB&D
selected  six transactions announced in 1995 as being most representative of the
CFX/Safety Fund transaction.
 
    The six transactions selected as  most representative are: Peoples  Heritage
Financial  Group  Inc.'s  acquisition  of  Bank  of  New  Hampshire Corporation;
Chittenden Corporation's acquisition of Flagship Bank & Trust Company; Community
Bankshares, Inc.'s acquisition of Centerpoint Bank; The
 
                                       35
<PAGE>
Co-operative Bank  of  Concord's acquisition  of  Bank of  Braintree;  BayBanks,
Inc.'s  acquisition of  Cornerstone Financial Corporation;  and Peoples Heritage
Financial Group Inc.'s acquisition of Bankcore, Inc.
 
    Within this group of six transactions, the median multiple of tangible  book
value  paid by the acquiror was 1.91, the maximum multiple paid was 2.30 and the
minimum multiple was  1.24. These  statistics can  be compared  to multiples  of
tangible  book value  of 2.17  and 1.94,  respectively, for  the two alternative
prices of the  CFX/Safety Fund transaction,  assuming that the  Per Safety  Fund
Share  Value  of the  Exchange  Ratio is  approximately  $26.14 for  the pooling
accounting transaction and $23.37 for the purchase accounting transaction  (such
values  being based on the  market price of CFX Common  Stock on January 4, 1996
multiplied by the Exchange Ratios of 1.7 and 1.52, respectively).
 
    With respect to  trailing 12 months  earnings multiples for  this same  data
sample,  the  median  price/earnings multiple  paid  was 12.29  and  the maximum
multiple (excluding  the acquisition  of weaker  earners) was  14.39, while  the
minimum  multiple was 10.00. These statistics  can be compared to price/earnings
multiples of 25.98 times and 23.16 times, respectively (based on the last twelve
months recorded earnings for Safety Fund), for the two alternative prices of the
CFX/Safety Fund transaction assuming that the Per Safety Fund Share Value at the
Exchange Ratio is  approximately $26.14 for  the pooling accounting  transaction
and  $23.37 for the purchase accounting  transaction (such values being based on
the market  price of  CFX Common  Stock on  January 4,  1996 multiplied  by  the
Exchange   Ratios  of  1.7   and  1.52,  respectively).   MB&D  noted  that  the
price/earnings multiple  for  the  CFX/Safety Fund  transaction  was  influenced
upward  by  Safety  Fund's  relatively  low  historic  earnings,  measured  as a
percentage of assets  or equity,  as compared to  the historic  earnings of  the
acquired  institutions  in the  six comparable  transactions. However,  based on
Safety Fund's  estimated  1996 earnings,  the  price/earnings multiple  for  the
CFX/Safety  Fund transaction would be 14.09 times and 12.60 times, respectively,
for the two alternative prices of the CFX/Safety Fund transaction.
 
    Pursuant to a letter agreement with Safety Fund dated January 4, 1996,  MB&D
will receive a fee of 1.00% of the value of the merger consideration received by
the  shareholders  of  Safety  Fund  for services  rendered  to  Safety  Fund in
conjunction with the proposed transaction.  The fee represents compensation  for
services rendered in connection with the analysis of the transaction, support of
the  negotiations and for the  rendering of its opinions.  Safety Fund paid MB&D
$100,000 following the  execution of  the Agreement and  an additional  $100,000
upon receipt of MB&D's final opinion included in this Proxy Statement. MB&D will
be  paid any additional amounts needed  to bring the total compensation received
to 1.00% of the  transaction value at  the time of  closing of the  transaction.
Based  upon a hypothetical transaction value  of $43 million, MB&D would receive
compensation of $430,000. In addition, Safety Fund has agreed to reimburse  MB&D
for  its  reasonable  out-of-pocket  expenses incurred  in  connection  with the
transaction. Safety Fund also  has agreed to indemnify  MB&D and its  directors,
officers  and employees against certain  losses, claims, damages and liabilities
relating to or arising out of MB&D's engagement, including liabilities under the
federal securities laws.
 
    MB&D has been engaged from time to time to provide services to CFX unrelated
to this Merger. The total consideration paid  by CFX to MB&D for these  services
during the past two years has been $7,500.
 
SURRENDER OF CERTIFICATES
 
    Within  three  business days  after the  Effective  Time, an  exchange agent
appointed by CFX and reasonably  satisfactory to Safety Fund ("Exchange  Agent")
will  mail  to  each record  holder  of Safety  Fund  Common Stock  a  letter of
transmittal, together  with instructions  for the  exchange of  its Safety  Fund
Common Stock certificates for certificates representing CFX Common Stock and the
cash  in lieu of  fractional shares, if  any, into which  the Safety Fund Common
Stock will have been converted as result of the Merger. Upon surrender of  their
Safety  Fund Common Stock certificates, such  holders will receive a certificate
for the number of whole  shares of CFX Common Stock  to which they are  entitled
and  a check  representing the  amount paid  in lieu  of issuing  any fractional
share. Until so
 
                                       36
<PAGE>
exchanged, the holder  of a  certificate representing Safety  Fund Common  Stock
outstanding  immediately prior to  the Effective Time shall  have no rights with
respect to such Safety Fund Common Stock except to surrender such certificate in
exchange for  a CFX  Common Stock  certificate and  cash in  lieu of  fractional
shares.  No dividends or other distributions  on CFX Common Stock declared after
the Effective Time will be made  to holders of unsurrendered Safety Fund  Common
Stock  certificates  until  the  holder  thereof  surrenders  such certificates.
Shareholders should not send  in their certificates  until they receive  further
instructions.
 
REPRESENTATIONS AND WARRANTIES; CONDITIONS TO THE MERGER; WAIVER
 
    The Agreement contains representations and warranties by Safety Fund and CFX
regarding  various customary legal, regulatory,  financial and business matters.
Except as  otherwise  provided  in  the  Agreement,  these  representations  and
warranties will not survive the Effective Time.
 
    The  obligations  of  CFX  and  Safety Fund  to  consummate  the  Merger are
conditioned upon,  among other  things: (i)  approval of  the Agreement  by  the
shareholders  of CFX and Safety Fund; (ii) the absence of orders prohibiting the
Merger; (iii)  the  receipt  of  all  necessary  regulatory  approvals  and  the
expiration   of  all  applicable  waiting  periods,  without  any  condition  or
requirement that causes the Board of Directors of CFX or Safety Fund to  abandon
the  Merger; (iv) the effectiveness under the Securities Act of the Registration
Statement and the absence  of any proceeding by  the Commission to suspend  such
effectiveness;  (v) approval for listing on the AMEX, subject to official notice
of issuance, of the shares of CFX Common Stock to be issued in the Merger;  (vi)
the  receipt of the tax  opinion described under "--  Certain Federal Income Tax
Consequences"; (vii) receipt  of all necessary  permits and authorizations;  and
(viii) receipt of other customary closing documents.
 
    Except  with  respect to  any required  shareholder or  regulatory approval,
substantially all of the conditions to consummation of the Merger may be  waived
at  any time by the party for whose benefit they operate, in a writing signed by
both parties, and the Agreement  may be amended or  supplemented at any time  by
written  agreement  of the  parties, except  that any  such waiver  or amendment
executed after approval  of the  Agreement by Safety  Fund's shareholders  which
reduces the amount or form of consideration to be delivered to such shareholders
pursuant to the Agreement requires the further approval of such shareholders.
 
REGULATORY AND OTHER APPROVALS
 
    The  Merger is subject  to approval by  the Federal Reserve  under the BHCA,
which requires that the  Federal Reserve take  into consideration the  financial
and  managerial  resources and  future prospects  of  the existing  and proposed
institutions and the convenience and needs of the communities to be served.  The
BHCA prohibits the Federal Reserve from approving the Merger if it would violate
certain  antitrust standards, unless it finds that the anticompetitive effect of
the Merger is clearly outweighed in  the public interest by the probable  effect
of the transaction in meeting the convenience and needs of the communities to be
served.  In addition,  the Federal Reserve  must take into  account the parties'
record of  performance in  meeting the  credit needs  of the  entire  community,
including  low  and moderate-income  neighborhoods. Federal  Reserve regulations
require publication of notice of the application for approval of the Merger  and
provide  an opportunity for the public to  comment on the application in writing
and to request a hearing. The Merger  may not be consummated until the 30th  day
after such approval (or such shorter period as the Federal Reserve may prescribe
with the concurrence of the Attorney General, but not less than 15 days), during
which  time the  United States Department  of Justice ("DOJ")  may challenge the
Merger on antitrust grounds.
 
    In addition, the Merger requires the approval of the MBBI. Such approval  is
based upon the determination that the proposed transaction does not unreasonably
affect competition among Massachusetts banking institutions and that it promotes
public  convenience and advantage. In making such a determination, the MBBI must
consider, among other things, a showing  of net new benefits, including  initial
capital  investment,  job creation  plans,  consumer and  business  services and
commitments to  maintain and  open branch  offices within  a bank's  statutorily
delineated local community.
 
                                       37
<PAGE>
    Prior  to approving the  Merger, the MBBI  must receive notice  from the MHP
Fund that  arrangements satisfactory  to the  MHP Fund  have been  made for  the
proposed  acquiror to  make 0.9 percent  of its assets  located in Massachusetts
available for call by  the MHP Fund for  a period of ten  years for purposes  of
funding  various affordable  housing programs.  Massachusetts law  provides that
such  funds  shall  bear  interest  at  rates  approved  by  the   Massachusetts
Commissioner  of Banks ("Commissioner"), which shall be based upon the cost (not
to include lost opportunity costs) incurred in making funds available to the MHP
Fund. Pursuant  to this  requirement, SFNB  and CFX,  as lender  and  guarantor,
respectively,  will  enter  into a  Loan  Agreement  with the  MHP  Fund's Board
pursuant to which SFNB will  agree to make funds available  for call by the  MHP
Fund's Board.
 
    Although   the  shares  issuable  upon  exercise  of  the  Option  represent
approximately 16.7  percent  of the  Safety  Fund  Common Stock  that  would  be
outstanding  after such  exercise, CFX  may not acquire  more than  5 percent of
Safety Fund Common Stock, pursuant to  the exercise of the Option or  otherwise,
without  prior approval of the  Federal Reserve. CFX has  applied to the Federal
Reserve for prior approval to exercise the Option following any applicable event
triggering the Option.
 
    To  the  extent  that  the  foregoing  information  describes  statutes  and
regulations,  it is  qualified in  its entirety  by reference  to the particular
statutes and regulations and the regulations promulgated under such statutes.
 
    The parties have filed applications for the foregoing regulatory  approvals.
The Merger will not proceed in the absence of all such required approvals. There
can  be  no assurance  that the  Federal Reserve  or the  MBBI will  approve the
Merger, and  if approved,  there can  be no  assurance as  to the  date of  such
approvals,  that such approvals will not  be conditioned upon matters that would
cause the Board of  Directors of CFX  or Safety Fund to  abandon the Merger,  or
that  no  action  will  be  brought  by  DOJ  challenging  the  Merger.  See "--
Representations and  Warranties;  Conditions  to the  Merger;  Waiver"  and  "--
Effective Time of the Merger; Termination."
 
    CFX  and Safety Fund  are not aware  of any other  governmental approvals or
actions that are  required for consummation  of the Merger  except as  described
above.  Should  any  such  approval  or  action  be  required,  it  is presently
contemplated that  such approval  or action  would be  sought. There  can be  no
assurance  that any such approval or action, if needed, could be obtained, would
not delay consummation of the  Merger and would not  be conditioned in a  manner
that would cause CFX or Safety Fund to abandon the Merger.
 
BUSINESS PENDING THE MERGER
 
    Under  the  terms of  the  Agreement, each  of  CFX, Safety  Fund  and their
respective subsidiaries  generally is  prohibited from  taking any  action  that
materially  affects the ability  of CFX or  Safety Fund to  obtain any necessary
governmental approvals, materially  increases the  period of  time necessary  to
obtain  such approvals, materially affects its  ability to perform its covenants
and  agreements   under   the   Agreement,  disqualifies   the   Merger   as   a
pooling-of-interests  for accounting purposes or a tax free reorganization under
Section 368 of the Code, or results in the representations and warranties of CFX
and Safety Fund in the Agreement not being  true and correct on the date of  the
Agreement  or at any  future date on or  prior to the Closing  Date. CFX may not
enter into other  acquisitions that  require the approval  of CFX  shareholders,
equal  or exceed $30  million in value,  or are reasonably  likely to materially
delay the Merger without the prior written consent of Safety Fund.
 
    Safety Fund, including its subsidiaries, is also required to use  reasonable
efforts to preserve intact its business organization and assets and maintain its
rights  and  franchises  and operate  its  business  in the  usual,  regular and
ordinary course.  In  addition, without  CFX's  prior consent  or  as  otherwise
provided  in the Agreement, Safety Fund may  not declare or pay any dividends or
other distributions on capital  stock other than  pursuant to specified  limits,
increase  compensation or  fringe benefits  of directors,  officers or employees
beyond customary limits, or take certain other actions.
 
    Safety Fund has also agreed in the Agreement, subject to certain exceptions,
that it will not authorize or  permit any of its officers, directors,  employees
or agents to directly or indirectly solicit,
 
                                       38
<PAGE>
initiate, or encourage any inquiries relating to, or the making of, any proposal
which  constitutes  a "takeover  proposal" (as  defined  in the  Agreement), 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 information,  relating to any  such inquiry  or proposal. Safety
Fund has agreed to notify CFX immediately of any such inquiry or proposal.
 
EFFECTIVE TIME OF THE MERGER; TERMINATION
 
    In the  event that  all conditions  to  the Merger  have been  satisfied  or
waived, the Effective Time shall be the time on the Closing Date that the Merger
becomes  effective  pursuant  to  applicable  provisions  of  Massachusetts law,
subject to the rights  of the parties  to terminate the  Agreement as set  forth
below.  Upon at  least three  business days  notice by  CFX, the  Merger will be
consummated at  a closing  to be  held as  soon as  practicable after  the  last
required approval has been obtained for the Merger and the merger of Safety Fund
with  and  into CFX  and the  last of  all required  waiting periods  under such
approvals have expired,  or such other  date as may  be agreed upon  by CFX  and
Safety Fund ("Closing Date").
 
    CFX  and Safety Fund each anticipates that the Merger will be consummated in
the second half of 1996. However, consummation  could be delayed as a result  of
delays  in obtaining the  necessary governmental and  regulatory approvals or if
any other condition to consummation of the Merger is not satisfied. There can be
no assurances as  to if  or when  such approvals will  be obtained  or that  the
Merger will be consummated. See "-- Regulatory and Other Approvals."
 
    The  Agreement may be  terminated at any  time prior to  the Effective Time,
whether before or  after approval of  the Merger by  the shareholders of  Safety
Fund:  (i) at any time  by the mutual written agreement  of CFX and Safety Fund;
(ii) by either Safety Fund or CFX in the event of a material breach by the other
party of any agreement, representation or warranty in the Agreement after notice
and an opportunity to cure; (iii) at  the election of either CFX or Safety  Fund
in  the event that the Closing Date does not occur on or before January 5, 1997,
or such later date as CFX and Safety Fund have agreed to in writing, subject  to
extension  in certain circumstances;  (iv) by either  Safety Fund or  CFX if the
shareholders of either party fail to approve the Agreement; (v) by either Safety
Fund or CFX if the Merger is disapproved by a relevant regulatory authority;  or
(vi)  by Safety Fund, if the CFX Trading  Price is below a certain price and CFX
elects not to adjust the  Exchange Ratio as provided  in the Agreement. See  "--
Terms of the Merger."
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
    Subsequent  to  the  Merger,  those  persons  serving  as  directors  of CFX
immediately prior  to the  Effective Time  will continue  as directors  of  CFX,
together  with four current directors of Safety Fund, Christopher W. Bramley, P.
Kevin Condron,  William  E.  Aubuchon,  III and  David  R.  Grenon.  Information
regarding  the  directors  of  CFX  is  included  in  documents  incorporated by
reference  herein.  See  "AVAILABLE   INFORMATION;  DOCUMENTS  INCORPORATED   BY
REFERENCE."  Information  regarding the  directors  of Safety  Fund  is included
elsewhere herein.  See "PROPOSAL  II  -- ELECTION  OF DIRECTORS  --  Information
Regarding Directors and Nominees."
 
    Under  the Agreement, CFX agrees, to  the extent permitted by applicable law
and appropriate  regulators,  to  maintain  SFNB  in  existence  as  a  separate
subsidiary of CFX for at least three years following the Effective Time, subject
to regulatory considerations, safe and sound banking practices and the fiduciary
duties  of CFX's directors. In addition, nine of those persons currently serving
as directors of SFNB will be  designated by CFX, after consultation with  Safety
Fund,  to  continue to  serve as  directors of  SFNB for  at least  three years,
subject to regulatory considerations, safe  and sound banking practices and  the
fiduciary  duties of CFX's directors,  and CFX initially will  elect up to three
additional CFX representatives as directors of SFNB.
 
                                       39
<PAGE>
EFFECT ON EMPLOYEES AND BENEFIT PLANS
 
    EMPLOYEES.  At  the Effective  Time, all employees  of Safety  Fund and  its
subsidiaries  shall be  employed by  CFX or  subsidiaries of  CFX, with employee
benefits which  in the  aggregate are  no less  favorable than  those  generally
afforded  to  other  employees  of CFX  or  CFX's  subsidiaries  holding similar
positions, subject  to  the terms  and  conditions under  which  those  employee
benefits are made available to such employees and to certain other provisions of
the Agreement. The parties are working to identify operational efficiencies that
may  be obtained through the consolidation of  the entities in the Merger. It is
anticipated that some positions may  be eliminated following the Effective  Time
and CFX is not under any continuing obligation with respect to the employment of
any specific employee of Safety Fund or SFNB other than the three officers whose
employment contracts are being assumed. See "-- Employment Agreements."
 
    At  the Effective Time, CFX will  assume Safety Fund's severance plan, which
covers all of the employees of Safety Fund and its subsidiaries. This  severance
plan  provides benefits comparable to those provided by CFX to its employees and
the employees of its subsidiaries.
 
    EMPLOYMENT AGREEMENTS.  Under the terms of the Agreement, CFX has agreed  to
assume  employment contracts  that Safety  Fund and/or  SFNB currently  has with
Christopher Bramley, James Garvey  and Stephen R.  Shirley, President and  Chief
Executive Officer, Senior Vice President and Senior Commercial Loan Officer, and
Senior  Vice President and  Senior Trust Officer,  respectively, of Safety Fund.
Pursuant to  those  employment contracts,  the  officers would  be  entitled  to
receive  severance  benefits  if  a  "terminating  event"  (as  defined  in  the
contracts) occurs within one year (with  respect to Messrs. Shirley and  Garvey)
or three years (with respect to Mr. Bramley) following a "change in control" (as
defined  in the contracts). The Merger constitutes a change in control under the
contracts. The severance benefits payable to Messrs. Shirley and Garvey would be
equal to  one  year's  annual  base  salary  (currently  $110,000  and  $99,000,
respectively),  payable over a twelve  month period and offset  by 50 percent of
any wages earned  from other employment.  The severance benefit  payable to  Mr.
Bramley  would  be  equal to  $400,000,  payable in  one  lump sum,  or,  at Mr.
Bramley's option, continuation  of his salary  (currently $211,600) and  certain
employee  benefits for  the remainder  of his  contract (which  was amended with
CFX's consent on January 5, 1996 to have a rolling two-year rather than one-year
term). Further  information  regarding  these  agreements  is  set  forth  under
"PROPOSAL  II  --  ELECTION OF  DIRECTORS  -- Executive  Compensation  and Other
Information."
 
    INDEMNIFICATION AND  INSURANCE.    The Agreement  provides  that  CFX  shall
indemnify  the directors and  officers of Safety Fund  and its subsidiaries with
respect to any  action arising  out of  or pertaining  to the  Agreement or  the
transactions  contemplated thereby.  The Agreement  also provides  that from and
after the  Effective Time,  CFX  will provide  indemnification, subject  to  the
limitations  and procedural requirements  contained in the  Agreement, for those
persons who served as directors and officers of Safety Fund or its subsidiaries,
at or before  the Effective Time,  in accordance with  the provisions of  Safety
Fund's  Articles of Organization and  Bylaws for a period  of six years from the
Effective Time.
 
    In addition,  CFX  has agreed  for  a period  of  not less  than  six  years
following the Effective Time to provide to those persons who served as directors
or  officers  of Safety  Fund on  or  before the  Effective Time,  Safety Fund's
existing insurance against  liabilities and claims  (and related expenses)  made
against  them resulting from their service as  such prior to the Effective Time,
or comparable  substitute  coverage.  It  is  currently  anticipated  that  such
coverage  may be obtained at a total  cost of approximately $21,000 per year. In
no event shall  CFX be  obligated to provide  insurance coverage  to an  insured
person  on more favorable terms than is currently provided to him or her in such
capacities. Safety  Fund agrees  to  renew any  such  existing insurance  or  to
purchase  any  "discovery period"  insurance  provided for  thereunder  at CFX's
request.
 
    SAFETY FUND STOCK OPTION  PLANS.  Certain  executive officers and  directors
have been granted stock options pursuant to the Safety Fund Stock Option Plans.
 
                                       40
<PAGE>
    The Safety Fund Stock Option Plans provide that if Safety Fund is a party to
a transaction involving a merger, any option granted under the Safety Fund Stock
Option  Plans shall pertain to and apply to  the securities to which a holder of
the number of shares  of Safety Fund  Common Stock subject  to the option  would
have  been entitled if he or she actually  owned the stock subject to the option
immediately prior  to  the time  such  transaction becomes  effective.  Although
Safety  Fund presently does  not intend to  do so, the  Safety Fund Stock Option
Plans provide that all unexercised  options granted thereunder may be  cancelled
by  Safety Fund  as of  the effective  date of  any such  transaction, by giving
proper notice to the holders thereof and by permitting the exercise, during  the
30-day  period  preceding  the  effective  date  of  such  transaction,  of  all
unexercised options in full.
 
    At the Effective Time, outstanding  obligations under the Safety Fund  Stock
Option  Plans will be assumed  by CFX and, except  as provided in the Agreement,
each stock option  outstanding under  the Safety  Fund Stock  Option Plans  will
become  an option to purchase, subject to  vesting, upon payment of the exercise
price, as adjusted by the Exchange Ratio, a number of shares of CFX Common Stock
equal to the Exchange Ratio  multiplied by the number  of shares of Safety  Fund
Common  Stock covered by such options, rounded  down to the nearest share. As of
March 28, 1996, there were outstanding under the Safety Fund Stock Option  Plans
options  held by five  present executive officers  of Safety Fund  to acquire an
aggregate of 42,750  shares of  Safety Fund Common  Stock at  an exercise  price
ranging  from $10.33 per share to $12.67 per share. Assuming consummation of the
Merger at  an  Exchange Ratio  of  1.7, the  outstanding  options held  by  such
executive  officers would become options to purchase 72,675 shares of CFX Common
Stock at an exercise price ranging from $6.08 to $7.45 per share. See  "PROPOSAL
I  -- PROPOSED  MERGER --Terms of  the Merger"  and "PROPOSAL II  -- ELECTION OF
DIRECTORS -- Safety Fund Stock Option Plans."
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
    Pursuant to Massachusetts  law, shareholders  of record on  the Record  Date
have  the right to dissent  to the Merger and, if  the Merger is consummated, to
receive compensation equal to  the "fair value" of  their shares of Safety  Fund
Common  Stock.  Any shareholder  desiring to  exercise such  statutory appraisal
rights will have the rights and duties and must follow the procedures set  forth
in  sections  85  to 98,  inclusive,  of chapter  156B  of the  General  Laws of
Massachusetts (the "Dissent Statute") in order  to perfect such rights. A  brief
summary  of the Dissent Statute  is set forth below.  The following summary does
not purport to  be a  complete statement  of the  procedures to  be followed  by
shareholders  desiring  to  exercise  their statutory  appraisal  rights  and is
qualified in its entirety by express reference to the Dissent Statute, the  full
text  of which is included in Appendix D attached hereto. Shareholders are urged
to read Appendix D in its entirety  since failure to comply with the  procedures
set forth therein may result in the loss of statutory appraisal rights.
 
    To exercise appraisal rights under Massachusetts law, a shareholder must (i)
deliver to Safety Fund, before the shareholder vote on the action giving rise to
such  appraisal rights,  a written  objection to  such action  stating that such
shareholder intends to demand payment for his or her shares through the exercise
of his or her statutory appraisal rights,  (ii) not vote in favor of or  consent
to  such action and (iii)  within twenty days after the  date of mailing to such
shareholder of  a written  notice that  the Merger  has become  effective,  make
written  demand  upon  Safety Fund  for  payment of  his  or her  shares  and an
appraisal of the value thereof. In  order to satisfy the requirements  described
in  clause (ii)  above, a  shareholder must  either vote  in person  or by proxy
against Proposal  I  or  abstain  from voting  on  such  proposal.  The  written
objection  described in clause (i) above may be  sent to Safety Fund at 470 Main
Street, Fitchburg, Massachusetts 01420, Attention: Mr. Christopher W. Bramley.
 
    After a shareholder makes a written demand for payment of his or her  shares
as  provided  above,  such  shareholder  ceases  to  be  entitled  to  notice of
shareholders' meetings, the right to vote and the right to receive dividends and
other distributions of Safety Fund, except in certain limited circumstances. The
Dissent Statute provides that, after a written  demand for payment is made by  a
dissenting  shareholder, such shareholder  shall not be  entitled to such rights
unless (i) a bill to determine the
 
                                       41
<PAGE>
fair value of such shareholder's shares is not timely filed as described  below,
(ii)  a bill to determine the fair value of the shares is dismissed with respect
to such shareholder,  or (iii)  such shareholder,  with the  approval of  Safety
Fund, withdraws his or her objections and accepts Safety Fund's action.
 
    Once  a  written demand  for  payment is  made  as described  above,  if the
dissenting shareholder and Safety Fund reach agreement on the fair value of such
shareholder's shares, Safety Fund will pay to such shareholder the fair value of
such shares within 30 days after the  expiration of the period during which  the
demand  may be made. If, within such 30-day period, the parties fail to agree as
to the fair value of  such shares, Safety Fund or  the shareholder may have  the
fair  value of the  stock of all dissenting  shareholders determined by judicial
proceedings by filing a bill in  equity in the Massachusetts Superior Court  for
Worcester  County within  four months after  the 30-day period  expires. For the
purposes of the Superior Court determination, the  value of the shares is to  be
determined  as of  the day preceding  the date  of the vote  of the shareholders
approving the  actions  giving  rise  to the  appraisal  rights,  and  shall  be
exclusive of any element of value arising from the expectation or accomplishment
of such actions.
 
    Failure  to satisfy all of  the conditions described above  and set forth in
the Dissent Statute will preclude  a shareholder's claim of statutory  appraisal
rights  under Massachusetts law. However, a shareholder who fails to perfect his
or her  statutory appraisal  rights will  nevertheless remain  a shareholder  of
Safety Fund entitled to all the rights and benefits appurtenant thereto.
 
    Under  the Dissent Statute,  the enforcement by  a dissenting shareholder of
such shareholder's right to receive payment for his or her shares in the  manner
provided thereby is stated to be the exclusive remedy of a shareholder objecting
to  the Merger, except upon the grounds that consummation of the Merger be or is
illegal or fraudulent as to that shareholder.
 
CERTAIN DIFFERENCES IN RIGHTS OF SHAREHOLDERS
 
    CFX is a  New Hampshire  corporation. The rights  of holders  of CFX  Common
Stock  are governed generally by the New Hampshire Business Corporation Act, RSA
293-A ("New Hampshire Corporate Law"), by the CFX Articles of Incorporation,  as
amended  (the  "CFX Articles")  and by  the  CFX By-Laws,  as amended  (the "CFX
By-Laws").
 
    Safety Fund is a Massachusetts corporation. The rights of holders of  Safety
Fund Common Stock are currently governed generally by the Massachusetts Business
Corporation  Law, Chapter  156B ("Massachusetts  Corporate Law"),  by the Safety
Fund Articles of Organization,  as amended (the "Safety  Fund Articles") and  by
the   Safety  Fund  By-Laws,  as  amended  (the  "Safety  Fund  By-Laws").  Upon
consummation of the Merger,  the shareholders of Safety  Fund (except those  who
exercise  dissenters' rights) will become shareholders  of CFX and as such their
rights will be governed by New Hampshire Corporate Law.
 
    The rights of shareholders of CFX and Safety Fund with respect to cumulative
voting, preemptive rights, dividends and repurchases of stock and classification
of directors are generally  comparable. Certain significant differences  between
the  rights  of  shareholders of  CFX  and  Safety Fund  with  respect  to other
provisions are set forth below.
 
    This summary contains a list of material differences, but is not meant to be
relied upon as an  exhaustive list or a  detailed description of the  provisions
discussed and is qualified in its entirety by reference to the CFX Articles, the
CFX By-Laws, the Safety Fund Articles and the Safety Fund By-Laws.
 
    SPECIAL  MEETINGS OF  SHAREHOLDERS.   CFX.  Pursuant  to the  CFX By-Laws, a
special meeting of shareholders may be called by the Chairman of the Board,  the
President, a Vice President, a majority of the board of directors or the holders
of at least 10% of the shares entitled to vote at the meeting.
 
    SAFETY  FUND.   Pursuant to  the Safety Fund  By-Laws, a  special meeting of
shareholders may  be  called  by the  Board,  the  Chairman of  the  Board,  the
President,  the directors or  the holders of  at least 40%  of the capital stock
entitled to vote at the meeting.
 
                                       42
<PAGE>
    INSPECTION OF RECORDS  BY SHAREHOLDERS.   CFX.   Pursuant  to New  Hampshire
Corporate  Law,  a shareholder  of a  corporation may  inspect and  copy, during
regular business hours at the corporation's principal office, certain records of
the corporation if the shareholder gives  the corporation written notice of  his
demand at least five business days before the date on which he wishes to inspect
and copy the records.
 
    SAFETY  FUND.  Pursuant  to Massachusetts Corporate Law  and the Safety Fund
By-Laws, the original, or attested copies,  of the Safety Fund Articles,  Safety
Fund  By-Laws and records of all meetings of the incorporators and shareholders,
and the  stock and  transfer records,  are available  for inspection  at  Safety
Fund's  principal  office by  any shareholder  at all  reasonable times  for any
proper purpose.
 
    ACTION BY  CONSENT  OF  SHAREHOLDERS.   CFX.    Pursuant  to  New  Hampshire
Corporate Law and CFX By-laws, any action required or permitted to be taken at a
shareholders'  meeting may be taken without a  meeting if the action is taken by
all the shareholders entitled to vote on the action, provided that the action is
evidenced by one or more written consents describing the action taken, signed by
the holders of all  of the issued  and outstanding shares  of stock entitled  to
vote upon such action.
 
    SAFETY FUND.  The Safety Fund By-Laws do not permit the shareholders to take
any action by consent.
 
    REMOVAL  OF  DIRECTORS.    CFX.   Under  New  Hampshire  Corporate  Law, the
shareholders of a corporation may remove  one or more directors with or  without
cause unless the articles of incorporation provide that directors may be removed
only  for cause. The  CFX Articles provide  that at any  meeting of shareholders
called expressly for the purpose, any Director may be removed from office by the
affirmative vote of the  holders of 75%  of the shares entitled  to vote or,  if
removal is for cause, then by a majority of the shares then entitled to vote.
 
    SAFETY FUND.  Under Massachusetts Corporate Law and the Safety Fund By-Laws,
a  Director may be removed from office (i)  with or without cause by the vote of
the holders of  a majority of  the shares entitled  to vote in  the election  of
directors  and (ii) with  cause by vote of  a majority of  the directors then in
office.
 
    VACANCIES ON THE  BOARD OF  DIRECTORS.  CFX.   New  Hampshire Corporate  Law
permits  and the CFX Articles provide that any vacancy in the board of directors
caused by  death, resignation,  retirement, disqualification,  removal or  other
cause,  shall be filled  by a majority  vote of the  remaining directors, though
less than a quorum. A director so chosen holds office for the unexpired term  of
the director's predecessor in office. Any directorship to be filled by reason of
an  increase in the authorized number of directors may be filled by the board of
directors for  a term  of office  continuing  only until  the next  election  of
directors by the shareholders.
 
    SAFETY  FUND.  The Safety Fund By-Laws provide that any vacancy in the board
of directors  may be  filled by  vote of  a majority  of the  directors then  in
office;  provided, however,  that if  at the  time of  such vacancy  there is an
"interested shareholder", such vacancy may only be filled by vote of at least  a
majority  of the  "continuing directors"  then in  office. The  term "interested
shareholder" generally includes any person who or which is the beneficial  owner
of  10%  or  more of  the  voting stock  of  Safety Fund.  The  term "continuing
directors" generally means any directors of  Safety Fund who are not  affiliated
with  the  interested shareholder.  A director  elected to  fill such  a vacancy
serves for the remainder of the full term of the class of directors in which the
vacancy occurred or the new directorship  was created and until such  director's
successor is elected and qualified, or until he sooner dies, resigns, is removed
or  becomes  disqualified. The  Safety  Fund Articles  and  By-Laws additionally
provide that should a director resign, be removed from office or die, and should
the remaining Directors fail to fill the vacancy within 45 days of the effective
date of  the resignation  or removal,  or within  45 days  of the  death of  the
director,  then the total number of  directors is automatically decreased by the
number of unfilled vacancies. The Safety Fund By-Laws provide that the board  of
directors  may not be enlarged by the addition of more than two directors in any
year, exclusive of
 
                                       43
<PAGE>
increases in the  number of  the directors in  connection with  the issuance  of
preferred  stock, unless the requirement is waived by the affirmative vote of at
least two-thirds of  the shareholders  or two-thirds  of the  directors then  in
office; provided that if at the time of such action by the directors there is an
interested  shareholder, such action in addition requires the vote of at least a
majority of the continuing directors then in office.
 
    BUSINESS COMBINATIONS.   CFX.  The  CFX Articles contain  a so-called  "fair
price"  provision pursuant to which certain business combinations (as defined in
the CFX Articles), including a merger or consolidation, require the approval  of
(i)  the holders of at least 80% of  the outstanding shares entitled to vote for
the election  of  directors unless  the  consideration  to be  received  by  the
shareholders  of CFX is of the same  value and form as the highest consideration
paid by the other party to  the business combination (the "Acquiring Party")  in
acquiring CFX common stock, and (ii) subject to the provisions in (i) above, the
vote  of the holders of at least 75%  of the outstanding shares entitled to vote
for the election of directors unless the business combination is approved by  at
least  two-thirds  of the  directors  of CFX  who  are not  affiliated  with, or
shareholders of, the Acquiring Party.
 
    The CFX Articles  allow the  board of  directors, in  evaluating a  business
combination  or a  tender or  exchange offer,  to consider,  in addition  to the
adequacy of  the amount  to be  paid on  connection with  any such  transaction,
certain  specified factors and any other factors the board deems relevant. Among
the factors the board may consider are:  the social and economic effects of  the
transaction  on  CFX,  its  employees,  depositors,  loan  and  other customers,
creditors and other  elements of  the communities in  which CFX  operates or  is
located;  the business  and financial  condition and  earnings prospects  of the
acquiring party or parties; and the competence, experience, and integrity of the
acquiring party or parties and its or their management.
 
    SAFETY FUND.   The Safety  Fund Articles  contain a  so-called "fair  price"
provision  pursuant to  which certain transactions  (defined in  the Safety Fund
Articles as a "Subject Transaction"), including a merger or consolidation, would
require, in addition to any other approval or consent required by law,  approval
by  (i) at least  80% of the  shares of each  class of the  stock of Safety Fund
outstanding and entitled to vote on the matter and by at least a majority of the
shares of each class  of the stock  of Safety Fund  outstanding and entitled  to
vote  on the matter which  are not owned, directly  or indirectly, by the entity
(other than  Safety  Fund) (x)  which  is a  party  to the  proposed  merger  or
consolidation,  (y) to which the assets of  Safety Fund are proposed to be sold,
leased, exchanged, transferred or distributed, or to which securities of  Safety
Fund  or any of  its subsidiaries are  proposed to be  issued or whose ownership
share of Safety Fund or any of its subsidiaries is proposed to be increased,  or
(z)  to which the  assets of Safety Fund  are proposed to  be distributed on any
dissolution or liquidation (in each case, the "Receiving Entity"); (ii) at least
80% of the directors of Safety Fund not affiliated with, or owners of shares of,
the Receiving  Entity (the  "Unaffiliated Directors");  or (iii)  a majority  of
Unaffiliated  Directors prior  to the date  on which the  Receiving Entity first
acquired any share  of stock of  Safety Fund.  The fair price  provision of  the
Safety  Fund Articles provides that a Subject  Transaction is not subject to the
foregoing requirements if (i) the transaction  is approved by the holders of  at
least  a  majority of  the shares  of each  class  of the  stock of  Safety Fund
outstanding and entitled to vote on the matter and by the holders of at least  a
majority of the shares of each class of the stock of Safety Fund outstanding and
entitled  to  vote  on the  matter  not owned  by  the Receiving  Entity  or any
shareholder of the Receiving Entity; and (ii) the aggregate of the cash and fair
market value of all consideration to be paid per share to the holders of  Safety
Fund  Common Stock  in connection  with the  transaction shall  be equal  to the
greatest of (x)  the highest price  per share  paid by the  Receiving Entity  in
acquiring  any of Safety  Fund's common stock;  (y) an amount  which is at least
three times the  market price  of Safety  Fund's common  stock on  the date  the
Receiving  Entity first acquired any share of Safety Fund's common stock; or (z)
an amount which is at least 15 times the aggregate earnings per share of  Safety
Fund  for  the four  immediately preceding  fiscal  quarters, provided  that the
consideration to be paid shall be in the same form as that paid by the Receiving
Entity for shares held by it.
 
    Under Massachusetts  Corporate  Law,  in determining  what  they  reasonably
believe  to be in the best interests of the corporation, corporate directors may
consider the interests of the corporation's
 
                                       44
<PAGE>
employees, suppliers, creditors and customers, the economy of the state,  region
and  nation,  community  and  societal  considerations,  and  the  long-term and
short-term interests of the corporation and its stockholders.
 
    AMENDMENTS TO  ARTICLES.    CFX.   New  Hampshire  Corporate  Law  generally
requires  the affirmative vote of a majority of the votes entitled to be cast on
the amendment by  any voting  group with respect  to which  the amendment  would
create  dissenters' rights, unless a greater vote is required by the articles of
organization of the corporation. The CFX Articles provide that the holders of at
least two-thirds of all of the shares  of CFX entitled to vote for the  election
of  directors  is required  to amend  or repeal,  or to  adopt any  provision in
contravention of or inconsistent with, the  CFX Articles. In addition, the  vote
of  the holders of at least 80% of all of the shares of CFX entitled to vote for
the election  of directors  is required  to amend  or repeal,  or to  adopt  any
provision  in contravention of or  inconsistent with, those provisions described
above in "-- Business Combinations."
 
    SAFETY FUND.  Under Massachusetts Corporate Law, a corporation may amend its
articles  of  organization  by  vote  of  two-thirds  of  each  class  of  stock
outstanding  and entitled to vote thereon or, if the articles of organization so
provide, by vote of  a lesser proportion  but not less than  a majority of  each
class  of  stock  outstanding and  entitled  to  vote thereon.  The  Safety Fund
Articles provide that the affirmative vote of at least 80% of the shares of each
class of the stock of Safety Fund  outstanding and entitled to vote is  required
to  amend or repeal the  section of the Safety  Fund Articles described above in
"-- Business Combinations" and in certain other respects.
 
    AMENDMENTS TO BY-LAWS.  CFX.  Pursuant to the CFX Articles and CFX  By-Laws,
the  CFX By-Laws  may be amended  by the affirmative  vote of a  majority of the
entire board  of  directors,  subject  to repeal,  change  or  adoption  of  any
contravening  or inconsistent provision only by vote  of the holders of at least
two-thirds of  all the  shares  entitled to  vote on  the  matter at  a  meeting
expressly called for that purpose.
 
    SAFETY  FUND.  Massachusetts Corporate Law  provides that the power to make,
amend or  repeal  by-laws is  vested  in  the shareholders,  provided  that  the
directors  may also  make, amend  or repeal  the by-laws,  if authorized  by the
articles of organization, except with respect to any provision thereof which  by
law,  the  articles  or  organization  or the  by-laws  requires  action  by the
shareholders. The Safety Fund By-Laws provide  that the Safety Fund By-laws  may
be amended by the affirmative vote of the holders of a majority of the shares of
each  class of the capital stock at the time outstanding and entitled to vote at
any annual or special meeting of shareholders, and by the affirmative vote of  a
majority  of the directors;  provided, however, that the  affirmative vote of at
least 80% of the  total number of  directors then in  office or the  affirmative
vote  of at least 80%  of the shares of each  class of Safety Fund's outstanding
stock entitled to  vote is  required to amend  any provision  governing (i)  the
power  to fix the size of the board  of directors, (ii) restrictions, if any, on
the ability to serve as a director following service as a director or officer of
another financial institution, (iii) the power to fill vacancies on the board of
directors, (iv) the automatic reduction in the size of the Board after a vacancy
remains unfilled for  45 days, (v)  the enlargement of  the board of  directors,
(vi)  the  division  of the  board  of  directors into  three  classes,  and the
apportionment of the directors among  the classes, (vii) resignation of  members
of  the board of directors, or (viii)  amendment of the Safety Fund By-Laws; and
further provided that the  directors may not amend  or repeal the provisions  of
the  Safety  Fund  By-Laws governing  (i)  the  removal of  directors,  (ii) the
indemnification of directors and (iii) the amendment of the Safety Fund By-Laws,
or any provisions  of the  Safety Fund  By-Laws which  by law,  the Safety  Fund
Articles  of  Organization or  the  Safety Fund  By-Laws  require action  by the
shareholders.
 
    ANTI-TAKEOVER STATUTES.  CFX.  New Hampshire does not have an  anti-takeover
statute applicable to CFX.
 
    SAFETY  FUND.   Under  Chapter  110F of  the  Massachusetts General  Laws, a
Massachusetts corporation,  like Safety  Fund, is  prohibited from  engaging  in
certain business combinations (defined by the
 
                                       45
<PAGE>
statute  to include certain  mergers and consolidations,  dispositions of assets
and issuances of  securities, as  well as  certain other  transactions) with  an
interested  shareholder  (defined  by the  statute  to include  holders  of five
percent or more of  the outstanding stock  of the corporation)  for a period  of
three  years  following  the date  that  such shareholder  became  an interested
shareholder, except under certain circumstances, which include prior approval by
the board of  directors of  the business  combination or  the transaction  which
resulted  in the shareholder  becoming an interested  shareholder, or subsequent
approval of the business combination by the board of directors and by a vote  of
at  least two-thirds of the  outstanding voting stock which  is not owned by the
interested shareholder. The statute includes an exception to the prohibitions of
the statute  if, upon  consummation of  the transaction  which resulted  in  the
shareholder  becoming an interested shareholder,  the shareholder owned at least
90% of the voting stock of the corporation.
 
    Under  Chapter  110D   of  the  Massachusetts   General  Laws,  any   person
(hereinafter,  the  "acquiror")  who makes  a  bona  fide offer  to  acquire, or
acquires, shares of  stock of  a Massachusetts corporation  that, when  combined
with  shares already owned, would increase  the acquiror's ownership to at least
20%, 33.33% or a majority of the  voting stock of such company, must obtain  the
approval  of a majority of  shares held by all  shareholders except the acquiror
and the officers and inside  directors of the corporation  in order to vote  the
shares acquired. The statute permits a Massachusetts corporation to elect not to
be  governed by its provisions  by including in its  articles of organization or
by-laws a provision pursuant to which the corporation "opts out" of the statute.
Safety Fund has not included such a provision in either its articles or by-laws.
 
    DISSENTERS' APPRAISAL RIGHTS.   CFX.  Under New  Hampshire Corporate Law,  a
shareholder is entitled to dissent from, and obtain payment of the fair value of
his  shares  in  the  event  of any  of  the  following  corporate  actions: (i)
consummation of  a  plan of  merger  to which  the  corporation is  a  party  if
shareholder  approval  is required  for  the merger  by  RSA 293-A:11.03  or the
articles of incorporation and the shareholder is entitled to vote on the merger,
or if the corporation is a subsidiary  that is merged with its parent under  RSA
293-A:11.04,  (ii)  consummation  of  a  plan of  share  exchange  to  which the
corporation is a party as the corporation whose shares will be acquired, if  the
shareholder  is entitled to  vote on the  plan, (iii) consummation  of a sale or
exchange of all, or substantially all, of the property of the corporation  other
than in the usual and regular course of business, if the shareholder is entitled
to  vote  on the  sale or  exchange, including  a sale  in dissolution,  but not
including a sale pursuant to court order or  a sale for cash pursuant to a  plan
by  which all  or substantially  all of  the net  proceeds of  the sale  will be
distributed to the shareholders within one year after the date of sale, (iv)  an
amendment of the articles of incorporation that materially and adversely affects
rights  in respect of a dissenter's shares in certain specified manners, and (v)
any corporate action  taken pursuant  to a shareholder  vote to  the extent  the
articles  of  incorporation,  bylaws or  board  resolution provides  a  right to
dissent.
 
    SAFETY FUND.    Under  Massachusetts Corporate  Law,  appraisal  rights  are
available in connection with statutory mergers or consolidations (unless no vote
of  shareholders  of  the  corporation  is required  to  approve  the  merger or
consolidation), with amendments to the articles of organization which  adversely
affect  the rights of shareholders, and with  the sale, lease or exchange of all
or substantially  all of  a corporation's  property and  assets. Such  appraisal
rights are not available when the corporation is to be the surviving corporation
and  no vote of its shareholders is required for the merger. No provision of the
Safety Fund  Articles  alters in  any  way the  appraisal  rights set  forth  in
Massachusetts Corporate Law.
 
    DERIVATIVE  PROCEEDINGS.    CFX.    Under  New  Hampshire  Corporate  Law, a
shareholder may bring suit on behalf of  a corporation if the shareholder was  a
shareholder of the corporation at the time of the act or omission complained of.
On  termination  of the  proceeding and  a  finding that  the commencement  of a
derivative action  by a  shareholder  was without  reasonable  cause or  for  an
improper  purpose, a court may require the plaintiff to pay to the parties named
as defendant the reasonable expenses, including legal fees, incurred by them  in
defense of such action.
 
                                       46
<PAGE>
    SAFETY  FUND.   Under Massachusetts Corporate  Law, a  shareholder may bring
suit on behalf  of a corporation  if the  shareholder was a  shareholder of  the
corporation   at  the  time  of  the  act  or  default  complained  of,  or  the
shareholder's stock devolved upon  him thereafter by operation  of law from  one
who was a shareholder at such time.
 
    ANTI-TAKEOVER  PROVISIONS -- RIGHTS  PLANS.  CFX.   CFX has  not adopted any
shareholders' rights plan.
 
    SAFETY FUND.   Safety Fund has  adopted a Shareholder  Rights Plan which  is
described   in  documents  incorporated  herein  by  reference.  See  "AVAILABLE
INFORMATION; DOCUMENTS INCORPORATED BY REFERENCE."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a  summary of the anticipated  material federal income  tax
consequences  of  the Merger  to  shareholders of  Safety  Fund. Because  of the
complexities of the federal income tax laws and because the tax consequences may
vary depending  upon a  shareholder's individual  circumstances or  tax  status,
shareholders are strongly encouraged to consult with their personal tax advisors
with  respect to the specific tax consequences  of the Merger to them, including
the tax consequences of applicable federal, state, local, foreign or other laws.
 
    The following is the opinion of Arnold  & Porter, counsel to CFX, as to  the
material federal income tax consequences of the Merger. That opinion is based on
laws, regulations, rulings and judicial decisions as they existed as of the date
of  the opinion. These authorities are all subject to change and such change may
be made with retroactive effect. Arnold & Porter cannot give any assurance that,
after any  such  change,  its opinion  would  not  be different,  and  does  not
undertake  any  responsibility to  update or  supplement  its opinion.  Arnold &
Porter's opinion  is  not a  complete  description  of the  federal  income  tax
consequences  of the Merger; for  example, the rules set  out in the opinion may
not apply to  a holder  of Safety  Fund Common Stock  in light  of the  holder's
particular circumstances or to holders subject to special rules, such as foreign
persons,  financial institutions, tax-exempt  organizations, insurance companies
and persons who  acquired shares  of Safety Fund  Common Stock  pursuant to  the
exercise of employee stock options or rights or otherwise as compensation.
 
    CFX  and  Safety  Fund  have  provided  Arnold  &  Porter  with  the  facts,
representations, and  assumptions  on  which  Arnold  &  Porter  has  relied  in
rendering  its opinion, which information is  consistent with the state of facts
that CFX and  Safety Fund believe  will be  existing as of  the Effective  Time,
including  (but  not limited  to) an  assumption  that other  than cash  paid to
dissenters and cash paid in lieu of  fractional shares, no cash will be paid  to
Safety  Fund's  shareholders  pursuant  to  the  Merger.  Based  on  such facts,
representations and assumptions, Arnold  & Porter has  opined that, for  federal
income  tax purposes:  (i) the Merger,  when consummated in  accordance with the
Agreement and certain related agreements, either will constitute or will be part
of a reorganization within the  meaning of Section 368(a)  of the Code; (ii)  no
gain  or loss will be  recognized by a shareholder  of Safety Fund who exchanges
all of the shareholder's  Safety Fund Common Stock  solely for CFX Common  Stock
pursuant  to the Merger (except as described below with respect to cash received
in lieu of a fractional share interest in CFX Common Stock); (iii) the aggregate
adjusted tax  basis  of the  CFX  Common Stock  received  by a  shareholder  who
exchanges  all  of the  shareholder's Safety  Fund Common  Stock solely  for CFX
Common Stock in the Merger will be the same as the aggregate adjusted tax  basis
of the Safety Fund Common Stock surrendered in exchange therefor, reduced by any
amount  allocable to a fractional share interest for which cash is received; and
(iv) the holding  period for CFX  Common Stock received  in exchange for  Safety
Fund  Common Stock will include the period during which the shareholder held the
Safety Fund Common Stock surrendered in  the exchange, provided that the  Safety
Fund Common Stock was held as a capital asset at the Effective Time.
 
    For  federal income tax purposes, a  shareholder of Safety Fund who receives
cash in lieu of a fractional share interest in CFX Common Stock will be  treated
as  having received such fractional share interest.  The cash received by such a
shareholder   in    lieu   of    a   fractional    share   interest    in    CFX
 
                                       47
<PAGE>
Common  Stock will be treated as received  in exchange for such fractional share
interest, and gain or loss generally  will be recognized for federal income  tax
purposes  measured by the difference between the amount of cash received and the
portion of the basis of the shares of Safety Fund Common Stock allocable to such
fractional share interest. Such gain or loss should be long-term capital gain or
loss if the shareholder's shares of Safety Fund Common Stock are held as capital
assets and have been held for more than one year at the Effective Time.
 
    A shareholder of Safety Fund  Common Stock who exercises dissenters'  rights
under the Dissent Statute and who receives cash payment of the fair value of the
holder's  shares of Safety Fund Common Stock  will be treated as having received
such payment in redemption  of such shares. Such  redemption will be subject  to
the  conditions  and  limitations of  Section  302  of the  Code,  including the
attribution rules of  Section 318  of the  Code. In  general, if  the shares  of
Safety  Fund Common  Stock are  held by  the holder  as a  capital asset  at the
Effective Time, a dissenting holder will recognize capital gain or loss measured
by the difference between  the amount of  cash received by  such holder and  the
basis  for  such  shares. If,  however,  such  holder owns,  either  actually or
constructively, any other  Safety Fund  Common Stock  or CFX  Common Stock,  the
payment  made to such  holder could be  treated as dividend  income. In general,
under the constructive ownership rules of  the Code, a holder may be  considered
to  own stock that is owned, and  in some cases constructively owned, by certain
related individuals or entities, as well  as stock that such holder (or  related
individuals  or entities) has  the right to  acquire by exercising  an option or
converting a convertible security. Each shareholder of Safety Fund Common  Stock
who contemplates exercising dissenters' rights should consult his or her own tax
advisor  as to  the possibility  that the  payment will  be treated  as dividend
income.
 
    As stated above,  the preceding  analysis is  based on  the assumption  that
other  than cash paid to dissenters and  cash paid in lieu of fractional shares,
no cash  will be  paid to  Safety Fund's  shareholders pursuant  to the  Merger.
However,  in the unlikely  event that (i)  a Pooling Determination  is not made,
(ii) the CFX  Trading Price  is below  $12.50 and  (iii) Safety  Fund elects  to
terminate  the  Agreement,  CFX may  adjust  the  Exchange Ratio  to  the amount
determined by dividing  $20.00 by the  CFX Trading Price  or make an  additional
cash  payment (in  either case  resulting in  a Per  Safety Fund  Share Value of
$20.00). See "--Terms of  the Merger." Should these  circumstances arise and  if
CFX  were  to make  such  an additional  cash  payment, the  federal  income tax
consequences of the Merger would be different than those described above.  Under
such circumstances, it is possible that the Merger would still either constitute
or  be part of a reorganization, but  that Safety Fund shareholders who exchange
their Safety Fund Common  Stock for CFX Common  Stock plus cash would  recognize
gain,  but not loss, as a result of the  Merger in an amount up to the amount of
cash received.
 
RESALE OF CFX COMMON STOCK
 
    The shares of CFX Common Stock issuable to shareholders of Safety Fund  upon
consummation  of the Merger have been registered under the Securities Act. It is
anticipated, and it is a condition to each of the parties' obligations to effect
the Merger, that such shares will be approved for listing, upon official  notice
of issuance, on the AMEX. Such shares may be traded freely by those shareholders
not  deemed to be  affiliates of Safety Fund  as that term  is defined under the
Securities Act. The term "affiliate"  generally means each person who  controls,
is controlled by or is under common control with, or is a member of a group that
controls, is controlled by or is under common control with, Safety Fund, and for
purposes hereof could be deemed to include all executive officers, directors and
10 percent shareholders of Safety Fund.
 
    Rule  145  promulgated  by  the Commission  under  the  Securities  Act will
restrict the sale of  CFX Common Stock received  in the Merger and  beneficially
owned  by those shareholders who are deemed  to be affiliates of Safety Fund and
certain of their family members and related interests. Such affiliates, provided
they are not affiliates of CFX at or following the Effective Time, may  publicly
resell  CFX  Common Stock  received by  them  in the  Merger subject  to certain
limitations, principally as to, among other things, the number of shares sold in
any quarter and the manner of sale, during the two years following the Effective
Time. After  the  two-year  period,  such affiliates  may  resell  their  shares
 
                                       48
<PAGE>
without restriction so long as there is adequate current public information with
respect  to CFX as  required by Rule  145. Persons who  become affiliates of CFX
prior to, at  or after the  Effective Time  may publicly resell  the CFX  Common
Stock  received by them in the Merger subject to similar limitations and subject
to certain filing requirements specified in  Rule 144. Affiliates also would  be
permitted  to resell  CFX Common  Stock received  in the  Merger pursuant  to an
effective registration statement under the  Securities Act or another  available
exemption   from  the  Securities  Act  registration  requirements.  This  Proxy
Statement does not cover any resales of CFX Common Stock received in the  Merger
by persons who may be deemed to be affiliates of CFX or Safety Fund.
 
    In addition, if the Merger is to be accounted for as a pooling-of-interests,
shares  of CFX Common Stock  and Safety Fund Common  Stock held by affiliates of
either company will  not be  transferable during  the period  beginning 30  days
prior  to the Effective Time and ending when financial results covering at least
30 days of  post-Merger combined  operations of CFX  and Safety  Fund have  been
published,  in  order  to  satisfy certain  requirements  of  the  Commission in
transactions  to  be   accounted  for   using  pooling-of-interests   accounting
treatment.  Under  the Agreement,  CFX has  agreed  to use  its best  efforts to
publish no later than  25 days after  the end of the  first calendar quarter  in
which  there are at least 30 days  of post-Merger combined operations (which 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 Commission's
Accounting Series Release No. 135.
 
    The Agreement provides  that CFX and  Safety Fund shall  use all  reasonable
efforts to cause those persons who may be deemed to be affiliates of Safety Fund
or  CFX to deliver to the other party,  as soon as practicable after the date of
the Agreement, and prior  to the Annual Meeting,  a written agreement  providing
that  such person will  not sell, pledge,  transfer or otherwise  dispose of any
shares of CFX Common Stock or Safety Fund Common Stock for the period  beginning
30  days prior to the Merger and  ending on the publication of financial results
covering at least 30 days of combined  operations of CFX and Safety Fund and  in
compliance  with the  Securities Act and  the rules  and regulations promulgated
thereunder. It is anticipated that each director and executive officer of Safety
Fund and CFX will execute such an agreement. Certificates of Safety Fund  Common
Stock surrendered for exchange pursuant to the Merger by any person deemed to be
an  affiliate shall not be exchanged for certificates representing shares of CFX
Common Stock  until CFX  has received  from that  person the  written  agreement
described in this paragraph.
 
ACCOUNTING TREATMENT
 
    In  the  Agreement, CFX  and  Safety Fund  agreed  to consummate  the Merger
whether it could be accounted for  as a pooling-of-interests transaction or  had
to  be accounted for as a purchase  transaction. CFX and Safety Fund also agreed
that they  would not  take any  action that  would disqualify  the Merger  as  a
pooling-of-interests  for  accounting purposes.  CFX and  Safety Fund  expect to
account for  the Merger  using the  pooling-of-interests method  of  accounting.
Under the pooling-of-interests method of accounting, the historical basis of the
assets  and liabilities  of CFX  and Safety  Fund will  be combined  and carried
forward at their previously  recorded amounts. Revenue and  expenses of CFX  and
Safety Fund will be combined at historically recorded amounts.
 
    In this connection, the Board of Directors of CFX has determined to omit the
regular  second quarter  cash dividend normally  payable to  CFX shareholders in
order to comply  with the  accounting rules related  to the  payment of  special
dividends  preceding  a business  combination.  Omission of  the  second quarter
dividend in an amount equal to the special dividend paid by CFX in January  1996
will  permit CFX to account for the Merger as a pooling transaction. CFX's Board
of  Directors  expects  to  resume  the  payment  of  normal  dividends  to  CFX
shareholders  in the third quarter  of 1996. As described  below, however, it is
still possible that  the Safety  Fund Merger  will not  qualify for  pooling-of-
interests accounting.
 
    Another  requirement of pooling treatment is  that affiliates of Safety Fund
cannot reduce their  holdings of Safety  Fund Common Stock  or CFX Common  Stock
received in the Merger, as the case may be, for a period beginning 30 days prior
to    the   Effective   Time   and   ending   upon   the   publication   of   at
 
                                       49
<PAGE>
least 30 days  of post-Merger combined  operations of CFX  and Safety Fund.  The
pooling-of-interests  method  will not  apply if  the holders  of more  than ten
percent  of  the  outstanding  shares  of  Safety  Fund  Common  exercise  their
dissenters'  rights. See "-- Background of the Merger," "-- Rights of Dissenting
Shareholders"  and  "PROPOSAL   II  --  ELECTION   OF  DIRECTORS  --   Principal
Shareholders."
 
    The Agreement provides that CFX is to consult with its independent certified
public  accountants  not  later  than  the  second  business  day  preceding the
Effective Time to  determine whether a  Pooling Determination can  be made.  The
Exchange  Ratio will differ depending upon  whether such a Pooling Determination
is made but a Pooling  Determination is not a  condition to consummation of  the
Merger,  which may  be consummated if  accounted for as  a purchase transaction.
Under the  purchase method  of accounting,  the net  assets and  liabilities  of
Safety Fund will be adjusted to their estimated fair market value at the date of
acquisition, and the purchase price over the fair market value of the net assets
will be recorded as goodwill, which is why the Per Safety Fund Share Value under
the  purchase  accounting  Exchange  Ratios are  lower  than  under  the Pooling
Determination Exchange Ratios. Pro  forma financial information provided  herein
is  presented  assuming use  of each  of  the pooling-of-interests  and purchase
accounting methods. See  "-- Terms of  the Merger" and  "PRO FORMA  CONSOLIDATED
FINANCIAL INFORMATION (UNAUDITED)."
 
    During the negotiation of the Agreement, both CFX and Safety Fund recognized
that,  while they  anticipated being  able to account  for the  transaction as a
pooling-of-interests, the  ability  of one  or  more Safety  Fund  shareholders,
holding  ten percent  or more  of the outstanding  shares of  Safety Fund Common
Stock, to  dissent  from the  transaction  could preclude  the  use of  such  an
accounting  treatment (the parties also noted  that Mr. Massad owned 9.9 percent
of the outstanding shares of  Safety Fund Common Stock  and had applied for  the
requisite  federal approval to acquire up to  51% of such shares, which approval
subsequently was granted). In recognition of this fact, the parties agreed  that
the  Merger would be consummated even if  the transaction could not be accounted
for as a pooling-of-interests (although with certain distinct results).  Because
the  Merger may be accounted for as either a pooling-of-interests transaction or
a purchase transaction, information  regarding the different possible  financial
results of the transaction under the two accounting methods is being provided to
shareholders herein.
 
STOCK OPTION AGREEMENT
 
    The  summary  information  below  in  this  Proxy  Statement  concerning the
material terms of  the Stock Option  Agreement is qualified  in its entirety  by
reference to the full text of such agreement, attached in its entirety hereto as
Appendix B.
 
    Under  the Stock Option Agreement, Safety Fund  has granted an Option to CFX
to purchase up to 332,000 authorized  but unissued shares of Safety Fund  Common
Stock  (constituting 16.7 percent of the shares of Safety Fund Common Stock that
would be outstanding following the exercise of the Option) at a price of $20 per
share. 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 therefor  shall be  adjusted appropriately.  If any  additional shares  of
Safety  Fund Common Stock  are issued or otherwise  become outstanding after the
date of the  Stock Option  Agreement (other than  as contemplated  in the  Stock
Option  Agreement), the number of shares of  Safety Fund Common Stock subject to
the Option shall be adjusted  so that, after such  issuance, it does not  exceed
19.99  percent of the number  of shares of Safety  Fund Common Stock then issued
and outstanding  without  giving effect  to  any  shares subject  to  or  issued
pursuant  to the  Option. At  the time  that CFX  submitted its  bid proposal to
Safety Fund, the $20 exercise price represented the prevailing market price  for
Safety Fund Common Stock.
 
    The purpose of the Option is to increase the likelihood that the Merger will
be  consummated by making it more difficult and more expensive for a third party
to acquire control of Safety Fund.  Accordingly, the Option is exercisable  only
upon   the  occurrence  of  certain  "Purchase  Events"  that  might  jeopardize
consummation of the  Merger pursuant  to the terms  of the  Agreement. The  term
"Purchase  Event" in the Stock Option Agreement generally relates to attempts by
one or more third
 
                                       50
<PAGE>
parties to acquire a significant interest in Safety Fund. Because a Safety  Fund
shareholder  has filed  an application for  approval with  and received approval
from federal  regulators  to acquire  securities  representing greater  then  10
percent  of the voting power  of Safety Fund, a  Purchase Event has occurred and
the Option is now exercisable, subject to the approval of the Federal Reserve as
discussed below.
 
    The Option would terminate:  (i) at the Effective  Time of the Merger;  (ii)
upon  termination of  the Agreement  in accordance  with the  provisions thereof
other than  as provided  in the  following  clause; or  (iii) six  months  after
termination  of the  Agreement due  to a  willful breach  by Safety  Fund of any
covenant contained therein.  For additional information  regarding the terms  of
the Option and events upon which it could be exercised, reference should be made
to the Stock Option Agreement, a copy of which is attached hereto as Appendix B.
 
    The  Stock Option Agreement also provides that at the election of CFX during
the nine  months immediately  following the  acquisition by  one or  more  third
parties  of 51% or more of the outstanding shares of Safety Fund Common Stock or
the execution by Safety Fund of an agreement  to sell 51% or more of the  voting
power  of  Safety  Fund or  any  subsidiary  (whether or  not  the  Stock Option
Agreement has been terminated), Safety Fund is required to repurchase the Option
from CFX together with any shares of  Safety Fund Common Stock purchased by  CFX
pursuant thereto, at a price specified in the Stock Option Agreement.
 
    Although   the  shares  issuable  upon  exercise  of  the  Option  represent
approximately 16.7  percent  of the  Safety  Fund  Common Stock  that  would  be
outstanding  after such exercise, CFX may not acquire more than 5 percent of the
Safety Fund Common Stock, pursuant to  the exercise of the Option or  otherwise,
without  prior approval of the  Federal Reserve. CFX has  applied to the Federal
Reserve for prior approval to exercise the Option following any applicable event
triggering the Option.

            PRO FORMA CONSOLIDATED FINANCIAL INFORMATION (UNAUDITED)
 
    The following unaudited  pro forma combined  condensed financial  statements
have  been prepared to  reflect the Merger on  both a pooling-of-interests basis
and a  purchase basis  and  the Milford  Acquisition on  a  pooling-of-interests
basis.  Under pooling-of-interests accounting  treatment for the  Merger and the
Milford Acquisition, the recorded assets and liabilities of CFX, Safety Fund and
Milford are carried forward to the  combined company at their recorded  amounts.
See  "PROPOSAL I  -- PROPOSED  MERGER --  Accounting Treatment."  Under purchase
accounting, the assets  and liabilities  of Safety  Fund are  adjusted to  their
estimated  fair  value  at the  date  of  acquisition. The  following  pro forma
financial statements reflect the  exchange of Safety Fund  Common Stock for  CFX
Common  Stock in connection  with the Merger at  an Exchange Ratio  of 1.7 for a
pooling-of-interests transaction and an  Exchange Ratio of  1.52 for a  purchase
transaction  and reflect  the exchange  of Milford  common stock  for CFX Common
Stock at an exchange ratio of 2.6446. The actual exchange ratios will depend  on
the  CFX Trading Price in the case of  the Merger and a similar determination in
the case of the Milford Acquisition. This unaudited pro forma combined financial
information should  be  read in  conjunction  with the  consolidated  historical
financial  statements  of  Milford,  including  notes  thereto,  incorporated by
reference herein,  the  consolidated  historical financial  statements  of  CFX,
including notes thereto, contained in the 1995 CFX Annual Report to Shareholders
that  accompanies this Proxy Statement and  is incorporated by reference herein,
and the consolidated historical financial  statements of Safety Fund,  including
notes  thereto, appearing in the 1995  Safety Fund Annual Report to Shareholders
that accompanies this Proxy Statement  and is incorporated by reference  herein.
See "AVAILABLE INFORMATION; DOCUMENTS INCORPORATED BY REFERENCE."
 
    The  unaudited pro forma combined condensed financial statements give effect
to the  Merger and  the  Milford Acquisition,  but  do not  reflect  anticipated
expenses  and  nonrecurring charges  which may  result from  the Merger  and the
Milford Acquisition  or  estimated  expense  savings  and  revenue  enhancements
anticipated to result from the Merger and the Milford Acquisition.
 
    The   unaudited  pro  forma  combined  financial  data  is  not  necessarily
indicative of the  financial position and  results of future  operations of  the
combined  entity or the actual financial position and results of operations that
would have been achieved had the Merger and Milford Acquisition been consummated
at the  dates indicated.  The  unaudited pro  forma combined  condensed  balance
sheets reflect preliminary pro forma adjustments made to combine CFX with Safety
Fund, utilizing both the pooling-of-interests accounting method and the purchase
accounting   method,  and   with  Milford   utilizing  the  pooling-of-interests
accounting  method,  respectively.  The  actual  adjustments  to  the  surviving
corporation's  accounts will be made as of  the Effective Time of the Merger and
may differ from those reflected in the pro forma financial statements.

    shares have been issued and are outstanding.

(2) The pro forma financial statements  reflect the exchange of Safety Fund  and
    Milford  Common Stock for CFX Common Stock in connection with the mergers at
    the exchange ratios of 1.7 and 2.6446, respectively.
 
    In combining the companies, a pro forma adjustment at December 31, 1995  was

    shareholders in  exchange for  the  outstanding shares  of Safety  Fund  and

    Common Stock, who would  otherwise have been entitled  to a fraction of  CFX
    Common  Stock,  will be  paid the  cash  value of  such fraction.  Such cash
    payments have not been reflected in the pro forma information.
 
(4) Pro forma  common shareholders' equity  per share was  computed by  dividing
    combined  historical common  shareholders' equity by  the sum  of the common
    shares outstanding at period end, adjusted to give effect to one or both  of
    the mergers, assuming the exchange ratios of 1.7 and 2.6446, respectively.
 
(5)   Pro  forma  weighted  average  common  shares  outstanding  represent  the
    historical weighted  average common  shares outstanding  of CFX  during  the

    Safety Fund  and Milford  adjusted to  give effect  to one  or both  of  the

                       CERTAIN REGULATORY CONSIDERATIONS
 
GENERAL
 
    Bank  holding  companies, banks  and many  of  their nonbank  affiliates are
extensively  regulated  under  both  federal   and  state  law.  The   following
information describes certain aspects of that regulation. To the extent that the
following  information describes  statutory provisions,  it is  qualified in its
entirety by reference to the particular statutory provisions and any regulations
promulgated thereunder.  The  following is  not  intended to  be  an  exhaustive
description of the statutes and regulations applicable to CFX's or Safety Fund's
business.   Additional  information  regarding  supervision  and  regulation  is
included  in  documents  incorporated   herein  by  reference.  See   "AVAILABLE
INFORMATION; DOCUMENTS INCORPORATED BY REFERENCE."
 
    CFX  is a  bank holding  company subject to  the supervision  of the Federal
Reserve under the BHCA.  As such, CFX  is a legal  entity separate and  distinct
from  its  subsidiary  banks ("Banks",  which  will include  SFNB  following the
Merger), and its  nonbanking subsidiaries.  Accordingly, the right  of CFX,  and
consequently  the right of creditors and  shareholders of CFX, to participate in
any distribution of  the assets  or earnings  of any  subsidiary is  necessarily
subject to the prior claims of creditors of the subsidiary, except to the extent
that  claims  of  CFX in  its  capacity as  a  creditor may  be  recognized. The
principal source of CFX's revenue and cash flows is dividends from its Banks and
nonbank subsidiaries. There  are legal limitations  on the extent  to which  the
Banks  can  finance  or  otherwise  supply  funds  to  CFX  and  its  nonbanking
subsidiaries.
 
    CFX Bank, a  subsidiary of  CFX, is a  New Hampshire-chartered  FDIC-insured
bank  and, therefore, is subject to  supervision and regulation by New Hampshire
bank regulators  and  the  FDIC. Orange  Savings  is  a  Massachusetts-chartered
FDIC-insured   savings  bank  subject  to  supervision  and  regulation  by  the
Commissioner and the  FDIC. SFNB is  a national banking  association subject  to
supervision  and regulation  by the  Office of  the Comptroller  of the Currency
("OCC").
 
RESTRICTIONS ON PAYMENT OF DIVIDENDS
 
    Because CFX derives  substantially all  of its  income from  the payment  of
dividends  by the Banks, its ability to pay dividends is affected by the ability
of its subsidiaries to pay dividends. The Banks are subject to various statutory
and regulatory  restrictions  on their  ability  to  pay dividends  to  CFX.  In
addition,  the FDIC, in the case of CFX  Bank and Orange Savings, and the OCC in
the case of SFNB, have authority to  prohibit any such Bank from engaging in  an
unsafe or unsound practice in conducting its business. The payment of dividends,
depending  upon the financial condition of the Bank in question, could be deemed
to constitute such an unsafe  or unsound practice. The  ability of the Banks  to
pay  dividends in the future  is presently, and could  be further, influenced by
federal and  state bank  regulatory  policies or  agreements and  by  regulatory
capital guidelines.
 
    In  addition, consistent  with its  policy regarding  bank holding companies
serving as a source of strength for their subsidiary banks, the Federal  Reserve
has  stated  that,  as a  matter  of  prudent banking,  a  bank  holding company
generally should not  maintain a rate  of cash dividends  unless its net  income
available  to  common  shareholders  has  been  sufficient  to  fund  fully  the
dividends, and  the  prospective  rate  of  earnings  retention  appears  to  be
consistent  with such holding company's capital needs, asset quality and overall
financial condition.
 
AFFILIATE TRANSACTION RESTRICTIONS
 
    The Banks are  subject to affiliate  transaction restrictions under  federal
law  which limit the transactions by subsidiary banks with or on behalf of their
parent company and to or on behalf  of any nonbank subsidiaries, whether in  the
form  of loans,  extensions of credit,  issuances of  guaranties, acceptances or
letters of  credit,  investments or  asset  purchases. Such  transactions  by  a
subsidiary  bank to its parent company or  to any nonbank subsidiary are limited
to 10 percent of a  bank subsidiary's capital and  surplus and, with respect  to
such  parent company and  all such nonbank  subsidiaries, to an  aggregate of 20
percent of such  bank subsidiary's capital  and surplus. An  exception to  these
qualitative restrictions is provided for transactions between insured banks that
are within the
 
                                       63
<PAGE>
same holding company structure where the holding company owns 80 percent or more
of  each institution. Further, such loans and extensions of credit generally are
required to be secured by eligible collateral in specified amounts. Federal  law
also  prohibits  subsidiary  banks  from  purchasing  "low-quality"  assets from
affiliates.
 
COMMUNITY REINVESTMENT ACT
 
    Bank holding  companies  and  their  subsidiary banks  are  subject  to  the
provisions  of the Community Reinvestment Act of 1977, as amended ("CRA"). Under
CRA, each subsidiary bank's record in meeting the credit needs of the  community
served  by  the  bank,  including  low-  and  moderate-income  neighborhoods, is
regularly assessed  by  the  bank's primary  regulatory  authority  (assessments
include   the  following   CRA  ratings  in   descending  order:  "Outstanding,"
"Satisfactory," "Needs to Improve" and "Substantial Noncompliance"). When a bank
holding company applies  for approval to  acquire a bank  or other bank  holding
company,  the Federal Reserve will review the assessment of each subsidiary bank
of the applicant bank  holding company, and  such records may  be the basis  for
denying  the application. At their most  recent respective CRA examinations, CFX
Bank received an overall CRA rating of "Outstanding" and Orange Savings and SFNB
received overall CRA ratings of "Satisfactory."
 
CROSS-GUARANTEE AND HOLDING COMPANY LIABILITY
 
    The Financial Institutions  Reform, Recovery,  and Enforcement  Act of  1989
contains  a "cross-guarantee" provision which could result in insured depository
institutions "commonly controlled" by  CFX being liable  for losses incurred  by
the FDIC in connection with assistance provided to, or the failure of, any other
insured  depository  institution  owned  by CFX.  Such  liability  could  have a
material adverse effect on the financial condition of any assessed Bank and CFX.
Under Federal Reserve policy, CFX  is expected to act  as a source of  financial
strength to each Bank and to commit resources to support each Bank. This support
may  be required  at times  when, absent  such policy,  CFX might  not otherwise
provide such support. In addition, any capital loans by CFX to any of the  Banks
would  be  subordinate in  right of  payment  to deposits  and to  certain other
indebtedness of the Banks.
 
    Under the  prompt  corrective  action  provisions  of  the  Federal  Deposit
Insurance  Corporation  Improvement  Act  of  1991  ("FDICIA")  and  the Federal
Reserve's source of strength policy, a  bank holding company may be required  to
infuse  sufficient capital into  a subsidiary insured  depository institution to
ensure  that  such  subsidiary  is  in  compliance  with  its  minimum   capital
requirements.  See  "--  Enforcement  Powers of  the  Federal  Banking Agencies;
Corrective Action" and "-- Capital Guidelines." Further, in the event of a  bank
holding  company's bankruptcy under Chapter 11  of the U.S. Bankruptcy Code, the
trustee will be deemed to have assumed  and is required to cure immediately  any
deficit under any commitment by the debtor holding company to any of the federal
banking  agencies to maintain the capital  of an insured depository institution,
and any claim for  breach of such obligation  will generally have priority  over
most other unsecured claims.
 
FDIC INSURANCE ASSESSMENTS
 
    Since  the deposits  of the  Banks are  insured by  the Bank  Insurance Fund
("BIF") of the FDIC,  the Banks are subject  to FDIC insurance assessments.  The
amount of FDIC assessments paid by individual insured depository institutions is
based  on  their relative  risk  as measured  by  regulatory capital  ratios and
certain other factors. Based  on this system,  FDIC regulations provided  during
the  first semi-annual period in  1995 for a minimum  assessment of 23 cents per
$100 of eligible  deposits for  the best-rated banks  and savings  associations,
with  a maximum of 31 cents per  $100 of eligible deposits for the weakest-rated
institutions. On  August 8,  1995, the  FDIC's Board  of Directors  reduced  the
assessment  rates for deposits insured by the BIF for the best-rated BIF-insured
banks for the second half  of 1995 to 0.044%  of insured deposits, but  retained
the  prior  assessment rates  applicable to  Savings Association  Insurance Fund
members. In November 1995, the FDIC  further reduced the BIF assessment for  the
1996  fiscal year  to the  legal minimum  of $2,000  a year  for the  best rated
institutions,
 
                                       64
<PAGE>
including CFX Bank, and 0.27% for the worst-rated institutions, because the  BIF
reserve  ratio exceeds  the 1.25% of  insured deposits required  by federal law.
SFNB currently pays premiums to the BIF at a rate of $.03 per $100 of  deposits,
totalling approximately $72,000 annually.
 
ENFORCEMENT POWERS OF THE FEDERAL BANKING AGENCIES; CORRECTIVE ACTION
 
    Failure   to  comply  with  applicable  laws,  regulations  and  supervisory
agreements could subject CFX and its  subsidiary banks, which will include  SFNB
following  the Merger, as well as officers, directors and institution-affiliated
parties of  these  institutions,  to administrative  sanctions  and  potentially
substantial civil money penalties.
 
    Under  FDICIA, the  federal banking  agencies possess  broad powers  to take
corrective action as  deemed appropriate for  an insured depository  institution
and  its holding companies. The extent of  these powers depends upon whether the
institution  in   question  is   considered  "well   capitalized,"   "adequately
capitalized,"    "undercapitalized,"    "significantly    undercapitalized"   or
"critically undercapitalized." As of  December 31, 1995, each  of the Banks,  as
well  as  SFNB,  exceeded  the  required  ratios  for  classification  as  "well
capitalized." The categorization  of depository institutions  under the  uniform
regulations  is solely  for the purpose  of applying the  federal bank agencies'
prompt corrective action powers  and is not  intended to be,  and should not  be
interpreted  as,  a  representation  of  the  depository  institution's  overall
financial condition or prospects.
 
    Generally, as an  institution is  deemed to  be less  well capitalized,  the
scope  and severity of  the agencies' powers  increase. The agencies' corrective
powers  can  include,  among  other  things,  requiring  an  insured   financial
institution  to adopt a capital restoration plan which cannot be approved unless
guaranteed by the institution's parent holding company; placing limits on  asset
growth and restrictions on activities; placing restrictions on transactions with
affiliates;  restricting the interest rate the  institution may pay on deposits;
prohibiting the institution  from accepting deposits  from correspondent  banks;
prohibiting   the  payment  of  principal  or  interest  on  subordinated  debt;
prohibiting the holding company from making capital distributions without  prior
regulatory approval; and, ultimately, appointing a receiver for the institution.
Business   activities  may  also  be  influenced  by  an  institution's  capital
classification. For instance, only  a "well capitalized" depository  institution
may  accept  brokered  deposits  without  prior  regulatory  approval  and  only
"adequately capitalized" institutions  may accept brokered  deposits with  prior
regulatory approval.
 
CAPITAL GUIDELINES
 
    CFX  and Safety Fund each are subject  to capital adequacy guidelines of the
Federal Reserve.  Under  the Federal  Reserve's  capital guidelines,  a  holding
company's  capital is divided into two tiers,  Tier 1 and Tier 2, the respective
components of which are described in materials incorporated herein by reference.
See  "AVAILABLE  INFORMATION;  DOCUMENTS  INCORPORATED  BY  REFERENCE."  Holding
companies are required to maintain a minimum ratio of total capital (Tier 1 plus
Tier  2 capital)  to total risk-adjusted  assets (which include  the credit risk
equivalents of certain off-balance sheet items)  of 8%, of which half (4%)  must
be  Tier 1 capital. In  addition, the Federal Reserve  requires a leverage ratio
(Tier 1  capital  to average  total  consolidated  assets) of  3%.  The  Federal
Reserve's   risk-based  and  leverage  ratios  are  minimum  supervisory  ratios
generally applicable  to  bank holding  companies  that meet  certain  specified
criteria,  including  that  they  have the  highest  regulatory  rating. Banking
organizations not meeting these  criteria are expected  to operate with  capital
positions  well above the minimum ratios. Each depository institution subsidiary
of CFX and  Safety Fund is  also subject to  similar minimum capital  guidelines
established  by  the subsidiary's  primary federal  regulator. The  federal bank
regulatory agencies  may  set  capital requirements  for  a  particular  banking
organization that are higher than the minimum ratios when circumstances warrant.
The  OCC has  requested that SFNB  endeavor to  maintain a leverage  ratio of at
least 6%  and the  SFNB Board  of Directors  has adopted  a resolution  to  that
effect.
 
    Effective  January  17,  1995, the  Federal  Reserve and  the  other federal
banking agencies  amended their  respective  risked-based capital  standards  by
explicitly  identifying concentrations of credit risk  and the risk arising from
non-traditional activities, as well as an institution's ability to manage  those
 
                                       65
<PAGE>
risks,  as important factors to be taken into account by the agency in assessing
an institution's overall  capital adequacy.  The federal  banking agencies  have
also  recently  adopted a  rule that  amends, effective  September 1,  1995, the
capital standards to include explicitly an institution's exposure to declines in
the economic value of its capital due  to changes in interest rates as a  factor
to  be considered in  evaluating capital adequacy.  This rule does  not codify a
measurement framework for assessing  the level of  interest rate exposure.  Such
agencies  have issued  for comment a  joint policy statement  that describes the
process to be used to  measure and assess the  exposure of an institution's  net
economic  value to  changes in  interest rates. It  is anticipated  that at some
future date such agencies would propose the establishment of an explicit minimum
capital requirement to account for such interest rate risks.
 
    Under federal banking laws, failure  to meet the minimum regulatory  capital
requirements  could subject  a banking institution  to a  variety of enforcement
remedies available to  federal regulatory  authorities, including,  in the  most
severe  cases, the termination of  deposit insurance by the  FDIC and seizure of
the institution.
 
    As of  December 31,  1995, CFX  and  Safety Fund's  capital ratios  and  the
capital  ratios of each of their subsidiary depository institutions exceeded the
minimum regulatory capital requirements  established by the appropriate  federal
regulatory agency. It is anticipated that, after the consummation of the Merger,
CFX  and its depository institution  subsidiaries, including SFNB, will continue
to exceed the minimum requirements.
 
RIEGLE-NEAL INTERSTATE BANKING AND BRANCHING EFFICIENCY ACT OF 1994
 
    On September  29,  1994,  the  President signed  into  law  the  Riegle-Neal
Interstate Banking and Branching Efficiency Act of 1994 ("IBBEA"), which permits
adequately  capitalized and adequately managed bank holding companies to acquire
banks in  any  state.  The  IBBEA  also permits  banks  in  separate  states  to
consolidate into single entities with branches in multiple states. Consequently,
effective  September 29, 1995, CFX has the authority to acquire any bank or bank
holding company,  and can  be acquired  by  any bank  or bank  holding  company,
located  anywhere in  the United  States. Further,  effective June  1, 1997, the
Banks will have the authority, subject to certain restrictions, including  state
opt-out  provisions,  to consolidate  with  other banking  subsidiaries  of CFX,
including SFNB. States may  affirmatively opt in, which  New Hampshire has  done
and  Massachusetts has legislation pending to  do, effective June 1, 1997. Among
other provisions, the IBBEA provides that interstate branches of national  banks
will  be  subject to  host state  laws, such  as intrastate  branching, consumer
protection, fair lending and community reinvestment laws, unless any such law is
preempted by federal law or is discriminatory in effect. The IBBEA provides that
interstate branches of  state banks  will be  subject to  the laws  of the  host
state.  In addition, among other things,  the IBBEA also increases the community
reinvestment requirements  applicable  to multi-state  depository  institutions.
This legislation may increase competition as banks branch across state lines and
enter new markets.
 
                      PROPOSAL II -- ELECTION OF DIRECTORS
 
GENERAL
 
    Safety Fund is governed by a Board of Directors which, under the Safety Fund
Articles  and the Safety Fund By-Laws, is  divided into three classes, as nearly
equal in number as possible, with the directors in each class serving a term  of
three years and until their successors are elected and qualified. As the term of
one  class expires,  a successor  class is  elected by  the shareholders  at the
annual meeting for that year.
 
    There are currently  17 directors  on the Board,  five of  whose terms  will
expire  at the Annual Meeting. Two of the five directors whose terms will expire
at the  Annual  Meeting will  retire  from the  Board  effective at  the  Annual
Meeting.  The Board  has set  the number  of directors  at 15,  effective at the
Annual Meeting.
 
                                       66
<PAGE>
    The Board  of Directors  has  selected and  recommended three  nominees  for
election  as directors, each to  serve for a three-year  term ending at the 1999
annual meeting of  shareholders or special  meeting in lieu  thereof, and  until
their  successors  are  duly  elected  and qualified,  or  until  the  Merger is
consummated. Each of the nominees is  currently serving as a director of  Safety
Fund.
 
    Unless authority is withheld, proxies in the accompanying form will be voted
FOR  the election  as directors  of the three  nominees. If  the proxy withholds
authority to  vote for  one or  more nominees  for director,  the  shareholder's
instructions will be followed.
 
    Safety Fund has no reason to believe that any of the nominees will be unable
to  serve. In the  event that any  nominee should not  be available, the persons
named in  the  proxy will  vote  for  the other  nominees  and may  vote  for  a
substitute for that nominee.
 
INFORMATION REGARDING DIRECTORS AND NOMINEES
 
    The  following table sets forth certain information (as of January 22, 1996)
regarding the current directors of Safety Fund (other than Bigelow Crocker,  Jr.
and George H. Heywood, Jr., both of whom will retire from the Board effective at
the  Annual Meeting) and the nominees for director. Each director also serves as
a director of  SFNB. No  director is  related to any  other director  or to  any
executive  officer of Safety Fund by blood,  marriage or adoption, and there are
no arrangements  or understandings  between any  director and  any other  person
pursuant to which the director was elected a director.

COMPENSATION OF DIRECTORS
 
    Directors of SFNB (all of whom are also directors of Safety Fund) receive  a
retainer  of $10,000 per year  and $200 for each  committee meeting and for each
meeting of the  Board of  Directors of  Safety Fund  or SFNB  that they  attend.
Directors  who are  also officers  of either  Safety Fund  or SFNB  are not paid
separately for their services as directors.
 
MEETINGS AND COMMITTEES OF THE BOARD
 
    The Board of Directors of Safety Fund held 11 meetings in 1995. The Board of
Directors of  SFNB  held 15  meetings  in 1995.  Safety  Fund has  a  Nominating
Committee;  it does  not have  an Audit  Committee or  a Compensation Committee.
However, SFNB has an  Audit Committee (which serves  as the Audit Committee  for
Safety  Fund) and  a Human  Resources/Compensation Committee  (the "Compensation
Committee").
 
    The Audit Committee's responsibilities  include reviewing any audit  reports
and  reporting to the full Board of  Directors. The Audit Committee met 12 times
in 1995. The Audit Committee members are Messrs. Howard (Chairman), D. Hall,  E.

Fund's employee benefit  policies and  the compensation of  senior officers  and
making  recommendations  with  respect  to  the such  matters  to  the  Board of
Directors.  The  Compensation  Committee  met   four  times  during  1995.   The
Compensation  Committee members are Messrs.  Yates (Chairman), Bramley, Condron,
D. Hall and Mara.
 
    The Nominating Committee's  responsibilities include making  recommendations
for  nominees as directors  to the Board of  Directors. The Nominating Committee

nominations by shareholders made  pursuant to notice delivered  to or mailed  to
and  received at the principal executive offices of Safety Fund not less than 60
nor more than  90 days prior  to the date  of the Annual  Meeting, provided  the
notice complies with the requirements set forth in the Safety Fund By-Laws.
 
    During  1995, each  director of  Safety Fund  attended at  least 75%  of the
aggregate of the total number of meetings that the Board held during the  period

    On  February  1,  1994, Safety  Fund  and  SFNB entered  into  an employment
agreement with Christopher  W. Bramley, President  and Chief Executive  Officer,
which  was amended  on October  6, 1995  and on  January 5,  1996. The agreement
provides for a rolling two-year term of employment, an annual base salary of not
less than  $200,000, stock  options to  purchase 37,500  shares of  Safety  Fund
Common  Stock (of which 22,500 options have  been granted to date) and a payment
in the amount of  $400,000 in the event  of a change in  control of Safety  Fund
under  certain circumstances  or, at Mr.  Bramley's option,  continuation of his
salary and certain employee benefits for the remaining term of his contract. The
Merger constitutes a change in control  under the agreement. The agreement  also
provides  for SFNB to  purchase term life  insurance in an  amount equal to five
times Mr. Bramley's base salary and  to contribute $30,000 to a retirement  fund
during  each year that Mr. Bramley is employed pursuant to the agreement. Safety
Fund has entered into a deferred  compensation agreement with Mr. Bramley  dated
as of December 29, 1995 for the purpose of defining the terms of such retirement
fund,  and established a  rabbi trust through which  such arrangement is funded.
Pursuant to such agreement,  Mr. Bramley is entitled  to receive the balance  of
the  fund in  60 monthly  installments commencing  not more  than 60  days after
termination of his employment or attainment of age 65.
 
    On June  1, 1994,  SFNB entered  into an  employment and  change of  control
agreement  with Stephen R. Shirley, Senior Vice President of SFNB. The agreement
provides for an  annual salary  of $105,000  per year  during each  year of  Mr.
Shirley's  employment with SFNB, or such other  rate as may be determined by the
Board of  Directors.  In  the  event  of  a  change  in  control  under  certain
circumstances,  SFNB has agreed to pay Mr. Shirley, in 12 equal installments, an
amount equal to  his then annual  base salary. If  Mr. Shirley becomes  employed
during  the time such payments are made to  him, from and after the date of such
employment, the  amounts payable  pursuant  to the  previous sentence  would  be
reduced by 50% of his wages from such employment.
 
    On  August 4, 1994,  SFNB entered into  an employment and  change of control
agreement with James Garvey,  Senior Vice President  and Senior Commercial  Loan
Officer. The terms of Mr. Garvey's agreement are substantially the same as those
of  Mr. Shirley's, except  that the agreement  provides for an  annual salary of
$95,000.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Directors and officers of  Safety Fund and  their associates were  customers
of,  and had transactions with,  SFNB in the ordinary  course of business during
1995. All outstanding loans and commitments were made on substantially the  same
terms,  including interest rates and collateral, as those prevailing at the time
for comparable transactions  with other persons  and did not  involve more  than
normal risk of collectability or other unfavorable features.
 
COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
    Charles  Troccia, who  became an executive  officer of SFNB  on December 18,
1995, failed to timely  file a Form 3.  Mr. Troccia does not  own any shares  of

                   AGREEMENT AND PLAN OF MERGER (AS AMENDED)
 
    THIS  AGREEMENT  AND  PLAN OF  MERGER  dated  as of  January  5,  1996 (this
"AGREEMENT"), by  and  between  CFX Corporation,  a  New  Hampshire  corporation
("Buyer"), and The Safety Fund Corporation, a Massachusetts corporation ("SAFETY
FUND").  (Certain capitalized terms used herein  shall have the meanings defined
in Section 11.1 hereof.)
 
    WHEREAS, Buyer intends to organize a Massachusetts corporation that will  be
a wholly-owned direct or indirect subsidiary of Buyer ("BUYER SUB"); and
 
    WHEREAS,  the respective Boards  of Directors of Buyer  and Safety Fund have
approved the acquisition of Safety Fund by Buyer pursuant to the merger of Buyer
Sub with and into Safety Fund (the "MERGER"); and
 
    WHEREAS, the parties hereto desire  that, following the consummation of  the
Merger,  Safety Fund will merge with and  into Buyer (the "BHC MERGER") pursuant
to a  merger  agreement in  a  form to  be  specified by  Buyer  and  reasonably
satisfactory to Safety Fund and consistent with the terms of this Agreement, and
that  Buyer may cause  the merger of  Orange Savings Bank  ("ORANGE SAVINGS"), a
wholly-owned subsidiary of  Buyer, with  Safety Fund National  Bank ("SFNB"),  a
wholly-owned subsidiary of Safety Fund (the "BANK MERGER"), pursuant to a merger
agreement  (the "BANK MERGER AGREEMENT") in a  form to be specified by Buyer and
reasonably satisfactory to  Safety Fund and  consistent with the  terms of  this
Agreement;
 
    NOW,  THEREFORE, in consideration of  the mutual covenants, representations,
warranties and  agreements herein  contained,  and of  other good  and  valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:
 
                                   ARTICLE I
                         THE MERGER AND THE BANK MERGER
 
    1.1   THE MERGER.  As promptly  as practicable following the satisfaction or
waiver of the conditions to  the parties' respective obligations hereunder,  and
subject to the terms and conditions of this Agreement, at the Effective Time (as
defined  in  Section  1.2  hereof): (a)  unless  theretofore  done,  Buyer shall
organize the Buyer Sub in accordance with Massachusetts law; (b) Buyer Sub shall
be merged  with  and  into  Safety  Fund, with  Safety  Fund  as  the  surviving
corporation  (the "SURVIVING  CORPORATION"); and  (c) the  separate existence of
Buyer Sub shall  cease and all  of the rights,  privileges, powers,  franchises,
properties,  assets, liabilities and obligations of Buyer Sub shall be vested in
and assumed by Safety Fund.
 
    1.2  EFFECTIVE TIME.  The Merger shall be effected by the filing of articles
of merger  (the  "ARTICLES  OF MERGER")  with  the  Secretary of  State  of  The
Commonwealth  of  Massachusetts (the  "SECRETARY OF  STATE") in  accordance with
Massachusetts law to become effective on the day of the closing ("CLOSING DATE")
provided for in  Article IX hereof  (the "CLOSING"). The  term "EFFECTIVE  TIME"
shall mean the time on the Closing Date (or a subsequent date not later than the
opening  of business on the next business day) when the Merger becomes effective
as set forth in the Articles of Merger.
 
    1.3   CHARTER  AND  BY-LAWS.   The  Charter  and By-laws  of  the  Surviving
Corporation  shall be the Articles of  Organization, as amended (the "CHARTER"),
and By-laws of Buyer Sub as in  effect immediately prior to the Effective  Time,
until thereafter amended as provided therein and by applicable law.
 
    1.4  DIRECTORS AND COMMITTEES OF SURVIVING CORPORATION AND BUYER.
 
    (a)The  Directors of Buyer Sub immediately prior to the Effective Time shall
       be the initial Directors of Surviving Corporation, each to hold office in
accordance with the Charter and By-Laws of Surviving Corporation.
 
    (b)Prior to or at the  Effective Time, four directors  of Safety Fund to  be
       designated  by Buyer after consultation with Safety Fund shall be elected
to the Board of Directors of Buyer, to be divided
 
                                      A-6
<PAGE>
proportionately among  the  classes.  The  Board of  Directors  of  Buyer  shall
nominate such persons for re-election, and support their re-election at the next
succeeding annual meeting of shareholders of Buyer to its Board of Directors, to
be  divided  proportionately  among  the  classes  of  directors.  Prior  to the
Effective Time, Buyer, in consultation with Safety Fund, shall reconstitute  the
committees  of its  Board of  Directors (as  well as  its joint management-Board
committees) so as to achieve substantially proportionate representation,  taking
into  account  to  the extent  practicable  the specific  skills,  education and
experience of the various designees, for the directors of Safety Fund designated
to become directors of Buyer.
 
    1.5   OFFICERS  OF  SURVIVING  CORPORATION.    The  officers  of  Buyer  Sub
immediately  prior  to  the Effective  Time  shall  be the  initial  officers of
Surviving Corporation, in each case  until their respective successors are  duly
elected or appointed and qualified.
 
    1.6  SURVIVING BANK.
 
    (a)In  the event Buyer determines to  accomplish the Bank Merger immediately
       following the Merger and the BHC Merger:
 
       (1) The Bank  Merger Agreement  shall specify  which of  SFNB and  Orange
           Savings  shall be the  surviving bank in  the Bank Merger ("SURVIVING
    BANK"), provided that the name of the Surviving Bank shall include the words
    "Safety Fund".
 
       (2) Buyer  agrees,  to  the  extent  permitted  by  applicable  law   and
           appropriate  federal  and  state  bank  regulators,  to  maintain the
    Surviving Bank in  existence as  a separate  subsidiary for  at least  three
    years  following the  Effective Time, subject  to regulatory considerations,
    safe and  sound  banking practices,  and  the fiduciary  duties  of  Buyer's
    directors.
 
       (3) The  officers of SFNB  immediately prior to  the Effective Time shall
           continue to  be the  officers  of the  Surviving Bank  following  the
    Effective  Time,  each to  hold office  in accordance  with the  Charter and
    By-Laws of the Surviving  Bank. Nine directors of  SFNB to be designated  by
    Buyer  after consultation with Safety Fund shall continue to be directors of
    the Surviving Bank  following the  Effective Time,  each to  hold office  in
    accordance with the Charter and By-Laws of the Surviving Bank. Buyer intends
    initially to elect up to three additional directors to serve on the Board of
    the  Surviving Bank. Buyer agrees that the continuing directors of SFNB will
    be  kept  in  place  for  at  least  three  years,  subject  to   regulatory
    considerations,  safe and sound banking  practices, and the fiduciary duties
    of Buyer's directors.
 
       (4) To the extent  any of  the Persons  designated in  this Agreement  to
           serve  as  a  director  of  Buyer  or  Surviving  Bank  is  unable or
    unwilling, as of the  Effective Time, to serve  in such position, Buyer  and
    Safety  Fund shall agree on  another member of the SFNB  Board to serve as a
    replacement for such designee.
 
    (b)In  the  event  Buyer  determines  not  to  accomplish  the  Bank  Merger
       immediately following the Merger and the BHC Merger, Buyer agrees to take
all  the measures specified in  Sections 1.6(a)(2), (3) and  (4) with respect to
SFNB to the same extent as they would have been applied to the Surviving Bank.
 
    (c)Nothing herein shall be deemed  to preclude Buyer from accomplishing  the
       Bank  Merger at  any time  from and  after the  Effective Time  as may be
determined by the Board of Directors of Buyer.
 
    1.7   ADDITIONAL  ACTIONS.   If,  at  any  time after  the  Effective  Time,
Surviving  Corporation shall consider or be advised that any further assignments
or assurances in law or any other  acts are necessary or desirable (a) to  vest,
perfect  or confirm, of record or  otherwise, in Surviving Corporation, title to
and possession of any property or right of Buyer Sub acquired or to be  acquired
by  reason of, or as a result of, the  Merger, or (b) otherwise to carry out the
purposes of this  Agreement, Buyer  Sub and  its proper  officers and  directors
shall be deemed to have granted to Surviving Corporation an irrevocable power of
attorney  to  execute  and  deliver  all  such  proper  deeds,  assignments  and
assurances in law and  to do all  acts necessary or proper  to vest, perfect  or
confirm title to and possession of such property
 
                                      A-7
<PAGE>
or  rights in Surviving Corporation  and otherwise to carry  out the purposes of
this Agreement; and the proper  officers and directors of Surviving  Corporation
are  fully authorized in the name of Buyer  Sub or otherwise to take any and all
such action.
 
    1.8  ADDITIONAL  AGREEMENTS.  Safety  Fund shall cause  SFNB to execute  and
deliver  the  Bank Merger  Agreement as  soon  as practicable  following Buyer's
request therefor. Safety Fund shall, and shall cause SFNB to, execute all  other
documents and take all actions as may be necessary or desirable for consummation
of the BHC Merger and the Bank Merger, as described in the recitals hereto.
 
    1.9   EFFECTS OF  THE MERGER.  At  and after the  Effective Time, the Merger
shall have the effects set forth in Chapter 156B, Section 80 of the General Laws
of The Commonwealth of Massachusetts, as amended.
 
    1.10  THE OPTION  AGREEMENT.  The parties  acknowledge that Safety Fund  and
Buyer  have entered into  that certain Stock  Option Agreement dated  as of even
date herewith (the "OPTION AGREEMENT") pursuant to which Safety Fund has granted
to Buyer the right to  purchase certain shares of  Safety Fund Common Stock  (as
defined in Section 2.1 hereof) upon terms and conditions specified in the Option
Agreement.
 
                                   ARTICLE II
                              CONVERSION OF SHARES
 
    2.1   CONVERSION.   At the Effective  Time, each share  of common stock, par
value $5.00 per share,  of Safety Fund ("SAFETY  FUND COMMON STOCK") issued  and
outstanding  immediately  prior to  the  Effective Time  (other  than Dissenting
Shares (as such term is  defined in Section 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
value  $0.66 2/3 per share,  of Buyer ("BUYER COMMON  STOCK") equal to one share
multiplied by  the  appropriate Exchange  Ratio  (rounded to  the  nearest  four
decimal places) determined in accordance with Section 2.4 or Section 2.5 hereof,
as the case may be (the "MERGER CONSIDERATION").
 
    2.2  CERTAIN DEFINED TERMS.  As used herein, the following capitalized terms
shall have the specified values or meanings.
 
    (a)"BUYER INDEX PRICE" shall mean $15.54 per share of Buyer Common Stock.
 
    (b)"BUYER  TRADING  PRICE" shall  mean the  average  closing price  of Buyer
       Common Stock  on  the  American Stock  Exchange  ("STOCK  EXCHANGE")  (as
reported  by  THE  WALL STREET  JOURNAL  or,  if not  reported  thereby, another
authoritative source)  for  the  ten  consecutive trading  days  ending  on  the
business  day before the date on which  the last regulatory approval required to
consummate the transactions contemplated hereby is obtained.
 
    (c)"POOLING DETERMINATION" shall  mean either (i)  a determination by  Buyer
       that   it  is  permissible  under  applicable  financial  and  regulatory
accounting principles  for Buyer  to  record the  Merger  under the  pooling  of
interests  method of accounting or (ii) a determination that, solely as a result
of actions  of Buyer  in breach  of this  Agreement, it  is impermissible  under
applicable  financial and regulatory  accounting principles for  Buyer to record
the Merger under the  pooling of interests method  of accounting and that  Buyer
will be required to use the purchase method of accounting for the Merger.
 
    2.3   DETERMINATION  OF APPLICABLE EXCHANGE  RATIO.  The  parties expect the
Merger to be accounted for under the pooling of interests method of  accounting.
In  view of the fact  that, among other possibilities,  a shareholder might take
actions so as  to preclude pooling  treatment for the  Merger, the parties  have
agreed  that the Merger Consideration  shall be paid as  follows. Not later than
the second
 
                                      A-8
<PAGE>
business day  preceding  the  Effective  Time,  Buyer  shall  consult  with  its
independent  certified public accountants as  to whether a Pooling Determination
can be made, and shall promptly advise Safety Fund of the determination. If,  as
of  the close  of business on  the day  preceding the Effective  Time, a Pooling
Determination shall have  been made,  the Exchange  Ratio shall  be the  Pooling
Exchange Ratio and the provisions of Section 2.4 shall apply. If as of such time
it  shall not have  been possible to  make a Pooling  Determination the Exchange
Ratio shall be  the Purchase Exchange  Ratio and the  provisions of Section  2.5
shall apply.
 
    2.4  POOLING OF INTERESTS ACCOUNTING EXCHANGE RATIOS.  The "POOLING EXCHANGE
RATIO" shall be determined as follows:
 
       (a) If  the Buyer Trading Price is equal to or greater than 85 percent of
           the Buyer Index Price and is no greater than 115 percent of the Buyer
    Index Price, the Pooling Exchange Ratio shall be 1.700.
 
       (b) If the Buyer Trading Price is  greater than 115 percent of the  Buyer
           Index  Price and is  no greater than  120 percent of  the Buyer Index
    Price, the Pooling Exchange Ratio shall be equal to:
 
                           Buyer Index Price X 1.955
                              Buyer Trading Price
 
       (c) If the Buyer Trading Price is  greater than 120 percent of the  Buyer
           Index Price, the Pooling Exchange Ratio shall be 1.629.
 
       (d) If the Buyer Trading Price is less than 85 percent of the Buyer Index

    2.6  CONVERSION OF STOCK.
 
    (a)All  Safety Fund Common Stock converted  into Buyer Common Stock pursuant
       to this Article II shall no longer be outstanding and shall automatically
be  cancelled  and  shall  cease  to   exist,  and  each  certificate  (each   a
"CERTIFICATE")  previously representing any such  Safety Fund Common Stock shall
thereafter represent the  right to  receive (i) the  number of  whole shares  of
Buyer  Common Stock, and (ii)  cash in lieu of  fractional shares into which the
Safety Fund Common Stock  represented by such  Certificate have been  converted.
Certificates previously representing Safety Fund Common Stock shall be exchanged
for  certificates representing  whole shares of  Buyer Common Stock  and cash in
lieu of fractional shares issued in consideration therefor upon the surrender of
such Certificates  in accordance  with this  Section 2.6,  without any  interest
thereon.
 
    (b)If  prior to the Effective Time Buyer  should split or combine its common
       stock (or other securities which are convertible into such common  stock)
or  pay a  dividend or  other distribution in  such common  stock or convertible
securities,  all  without  Buyer  receiving  consideration  therefor,  then   an
appropriate  and proportionate adjustment  shall be made  to the Exchange Ratio,
the Buyer Index Price and the Buyer Trading Price.
 
    (c)At the Effective Time, all shares of Safety Fund Common Stock held in the
       treasury of  Safety  Fund  other  than in  a  fiduciary  capacity  or  in
connection with debts previously contracted and all shares of Safety Fund Common
Stock owned by Buyer or owned beneficially by any subsidiary of Buyer other than
in  a fiduciary capacity or in connection with debts previously contracted shall

    2.7   PROCEDURES  FOR  EXCHANGE  OF SAFETY  FUND  COMMON  STOCK  FOR  MERGER
CONSIDERATION.
 
    (a)   BUYER TO MAKE SHARES AVAILABLE.   Buyer shall take all steps necessary
on and as of the Effective Time to deliver to the Exchange Agent (as hereinafter
defined), for  the benefit  of  the holders  of  Certificates, for  exchange  in
accordance  with  this Section  2.7, certificates  representing shares  of Buyer
Common Stock and the cash  in lieu of fractional shares  to be paid pursuant  to
this  Section 2.7 (such cash and certificates  for shares of Buyer Common Stock,
together  with  any  dividends  or  distributions  with  respect  thereto  being
hereinafter  referred  to as  the  "EXCHANGE FUND")  to  be issued  and  paid in
exchange for  outstanding  Safety Fund  Common  Stock in  accordance  with  this
Agreement. The Exchange Agent shall be such banking institution, corporate trust
company,  or  other  stock  transfer agent  appointed  by  Buyer  and reasonably
satisfactory to Safety  Fund to act  as exchange agent  hereunder. The  Exchange
Agent  shall act as agent  on behalf of record  holders (individually, a "RECORD
HOLDER") of Safety Fund  Common Stock at the  Effective Time, other than  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), or any Person holding Dissenting Shares.
 
    (b)    EXCHANGE  OF CERTIFICATES.    Within  three business  days  after the
Effective Time, Buyer shall take all steps necessary to cause the Exchange Agent
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
 
                                      A-10
<PAGE>
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
be entitled to receive in exchange therefor (x) a certificate for the number  of
whole  shares of Buyer Common  Stock to which such  holder of Safety Fund Common
Stock shall have become entitled pursuant to the provisions of this Section  2.7
and  (y)  a check  representing the  amount of  cash in  lieu of  the fractional
shares, if  any, which  such  holder has  the right  to  receive in  respect  of
Certificates surrendered pursuant to the provisions of this Section 2.7, and the
Certificates  so surrendered  shall forth  with be  cancelled. In  the event any
Certificate shall have  been lost, stolen  or destroyed, upon  the making of  an
affidavit  of that  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 with respect  to such Certificate,  the Exchange Agent  will
issue  in exchange  for such  lost, stolen  or destroyed  Certificate the Merger
Consideration deliverable  in  respect  thereof.  Certificates  surrendered  for
exchange by any person who is 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 certificates  representing shares  of Buyer  Common
Stock until Buyer has received 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 unsurrendered Certificate until
the holder  thereof shall  surrender such  Certificate in  accordance with  this
Section  2.7.  After the  surrender  of a  Certificate  in accordance  with this
Section 2.7, 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  which such  holder would
otherwise be entitled to receive pursuant to Section 2.7(b) 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
 
                                      A-11
<PAGE>
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 advance any transfer or other taxes required by reason of the
payment to  a  person  other  than the  registered  holder  of  the  Certificate
surrendered,  or  required  for any  other  reason,  or shall  establish  to the
satisfaction of  the Exchange  Agent  that such  tax has  been  paid or  is  not
payable.
 
    (f)   CLOSING OF TRANSFER  BOOKS.  From and  after the Effective Time, there
shall be no transfers on the stock  transfer books of Safety Fund of the  Safety
Fund  Common Stock  which were  outstanding immediately  prior to  the Effective
Time. If, after the  Effective Time, Certificates  representing such shares  are
presented  for transfer to the  Exchange Agent, they shall  be exchanged for the
Merger Consideration and cancelled as provided in this Section 2.7.
 
    (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 maybe 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.
 
    2.8  BUYER SUB COMMON STOCK.  Each share of common stock of Buyer Sub 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.
 
    2.9  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
receive, or be  exchangeable for,  the Merger Consideration,  but, instead,  the
holders  thereof shall  be entitled  to payment of  the appraised  value of such
Dissenting Shares in accordance  with the provisions of  Chapter 156B, 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 there
upon 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.
 
    2.10  STOCK  OPTIONS.  (a)   At the  Effective Time, each  holder of a  then
outstanding  stock option  to purchase  Safety Fund  Common Stock  ("SAFETY FUND
OPTION") pursuant to the 1984 Incentive Stock Option Plan or the 1994  Incentive
and  Nonqualified Stock Option Plan (collectively, the "SAFETY FUND STOCK OPTION
PLANS") (it being understood that the aggregate number of shares of Safety  Fund
Common  Stock subject to purchase  pursuant to the exercise  of such Safety Fund
Options is not and shall not be  more than 65,850), whether vested or  unvested,
will be assumed by Buyer. Each Safety Fund Option so assumed by Buyer under this
Agreement  shall  continue  to have,  and  be  subject to,  the  same  terms and
conditions set forth in the Safety Fund Stock Option Plans immediately prior  to
the Effective Time, except that (i) such Safety Fund Option shall be exercisable
(when vested) for that number of whole shares of Buyer Common Stock equal to the
product  of the  number of  shares of  Safety Fund  Common Stock  covered by the
Safety Fund Option multiplied by the Exchange Ratio,
 
                                      A-12
<PAGE>
provided that any  fractional share of  Buyer Common Stock  resulting from  such
multiplication shall be rounded down to the nearest share; and (ii) the exercise
price  per share of Buyer Common Stock shall  be equal to the exercise price per
share of Safety Fund  Common Stock of  such Safety Fund  Option, divided by  the
Exchange  Ratio, provided that  such exercise price  shall be rounded  up to the
nearest cent.
 
    (b)After the  Effective  Time,  Buyer  shall issue  to  each  holder  of  an
       outstanding  Safety  Fund  Option  a  document  evidencing  the foregoing
assumption of such Safety Fund Option by Buyer.
 
    (c)It is the intention of the  parties that the Safety Fund Options  assumed
       by  Buyer qualify following the Effective Time as incentive stock options
as defined in Section 422 of the Internal Revenue Code of 1986, as amended  (the
"CODE")  to the extent that the Safety Fund Options qualified as incentive stock
options immediately prior to the Effective Time.
 
    (d)Buyer shall not issue or pay for any fractional share otherwise  issuable
       upon exercise of a Safety Fund Option. Prior to the Effective Time, Buyer
shall  reserve for issuance  (and, if not previously  registered pursuant to the
Securities Act, register) the number of  shares of Buyer Common Stock  necessary
to  satisfy Buyer's  obligations with  respect to  the issuance  of Buyer Common
Stock pursuant to the exercise of Safety Fund Options.
 
    (e)The provisions of this Section 2.10 are expressly intended to be for  the
       irrevocable  benefit of,  and shall be  enforceable by, each  holder of a
Safety Fund Option and his or her heirs and representatives.
 
    2.11  TERMINATION, NOTICE AND CURE.  (a)  If (i) the Buyer Trading Price  is
less  than $11.65  and a  Pooling Determination  can be  made or  (ii) the Buyer
Trading Price is less  than $12.50 and a  Pooling Determination cannot be  made,
Safety  Fund may  elect by  giving written  notice to  Buyer prior  to the third

       (2) in  the event the Exchange Ratio  cannot be a Pooling Exchange Ratio,
           Buyer may elect  either to (X)  increase the Exchange  Ratio to  that
    Exchange  Ratio which when multiplied by the Buyer Trading Price has a value
    of $20.00 or (Y)  offer an Exchange  Ratio of 1.600 plus  an amount of  cash
    which  when added to the product of 1.600 and the Buyer Trading Price has an
    aggregate value of $20.00 per share of Safety Fund Common Stock;
 
    (b)In the event Buyer makes an election referred to in the preceding Section
       2.11(a), this Agreement shall not terminate and the Exchange Ratio  shall

not elect to increase the Exchange Ratio, this Agreement shall terminate on  the
date  established as the Closing Date with the consequences specified in Section

performance  of  this  Agreement or  the  Option  Agreement by  Safety  Fund nor
consummation of  the transaction  contemplated hereby  or thereby  requires  any
consent,  approval, authorization or  permit of, or  filing with or notification
to, any  court, administrative  agency or  commission or  other governmental  or
regulatory authority or instrumentality, domestic or foreign, including, without
limitation,  any  Bank  Regulator  (as  hereinafter  defined),  except  (i)  for
applicable requirements, if any, of the Securities Act, the Exchange Act,  state
takeover  laws, and  filing and recordation  of appropriate  merger documents as
required by Massachusetts, New Hampshire and Federal law, (ii) for consents  and

under this Agreement, or would not have a Material Adverse Effect on Safety Fund
and the Safety Fund Subsidiaries, taken as a whole, or on Buyer.

    3.11    TAXES  AND  TAX  RETURNS.    (a)    Safety  Fund,  all  Safety  Fund

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

or withholdings relating to any tax withholding, social security or unemployment
provisions of the  applicable federal, state  and local laws,  except where  the
failure to do so would not have a Material Adverse Effect on Safety Fund and the

Safety Fund  Financial  Statements  in  which  such  reserves  or  accruals  are
established  and  the  date hereof,  neither  Safety  Fund nor  any  Safety Fund

tax, assessment or  governmental charge the  failure to pay  which would have  a

settled and paid  or adequately reserved  against in the  Safety Fund  Financial
Statements  and  no requests  for  waivers of  the time  to  assess any  tax are
pending. Safety Fund and the Safety Fund Subsidiaries file consolidated  federal

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

course  of  business; use  reasonable efforts  to  preserve intact  its business
organization and assets  and maintain  its rights  and franchises;  and 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.
 
    (b)   NEGATIVE  COVENANTS.  Safety  Fund agrees  that from the  date of this
Agreement to the Effective Time,  except as otherwise specifically permitted  or
required  by this Agreement,  or consented to  by Buyer in  writing, Safety Fund

       (1) change or waive any provision of its Charter or By-laws;
 
       (2) change the number of shares of its authorized or issued capital stock
           (except (i) as may be required by the Option Agreement, (ii) for  the

    stock  options under the Safety Fund  Stock Option Plans, as contemplated by
    Section 3.2(b) hereof,  and (iii)  in connection  with its  adoption of  the
    Shareholder Rights Plan);
 
                                      A-27
<PAGE>
       (3) except in connection with its adoption of the Shareholder Rights Plan
           or as described in SCHEDULE 6.10, 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 the Safety Fund  Subsidiaries, or any securities convertible into
    shares of such stock; except that (i) Safety Fund may issue shares of Safety
    Fund Common  Stock  or  permit  treasury shares  to  become  outstanding  in
    accordance  with the terms of  the Safety Fund Stock  Option Plans, and (ii)
    Safety Fund  may  issue shares  of  Safety Fund  Common  Stock to  Buyer  in

    and $.09 per share in the first,  second, third and fourth quarters of  1996
    and the first quarter of 1997, respectively, declared and paid in accordance

    and for  dividends  paid by  any  Safety  Fund Subsidiary  to  Safety  Fund,

    may be increased to the Increased  Dividend (as defined below) per share  of
    Safety  Fund Common Stock beginning  in the first quarter  of 1997, and (ii)
    that the parties agree (x) to consult with respect to the amount of the last
    Safety Fund quarterly dividend payable prior to the Effective Time with  the
    objective  of assuring that the shareholders of Safety Fund do not receive a
    shortfall, or dividend or distribution from both Safety Fund and Buyer,  for
    such  quarter based on the  record and payment dates  of their last dividend
    prior to the Merger and the record  and payment dates of the first  dividend
    of  Buyer following the  Merger and (y)  that Safety Fund  may pay a special
    dividend to holders of record of Safety Fund Common Stock immediately  prior
    to  the Effective Time consistent with the objective described in clause (x)
    above. The parties agree that Buyer  dividends paid in any calendar  quarter
    are paid with respect to the then-preceding calendar quarter and that Safety
    Fund  dividends to be paid in any calendar quarter will be paid with respect

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
information, relating to any such inquiry or proposal. Nothing contained in this

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

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

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.

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. Safety
Fund shall provide  and shall request  its auditors to  provide Buyer with  such
historical  financial information  regarding it  (and related  audit reports and
consents) as Buyer may reasonably request for securities disclosure purposes.

transactions contemplated hereby. The date of the Special Meeting shall occur as
soon as practicable following the effectiveness of the Registration Statement on
Form S-4 (as more fully described in Section 7.1) filed with the SEC. The  Board

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

within  the meaning of Section 368(a) of the Code or the treatment of the Merger
as a pooling of interests for accounting purposes.

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

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 consummated  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"

    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 IV 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

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 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.

    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 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 non appealable, 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(a)  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(a)  except  to  the extent  such  failure  materially prejudices  it.  As a
condition to receiving indemnification under Section 6.11(a), 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 the irrespective 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(a) 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(a)
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.

<PAGE>
    (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(d) 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 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  there under 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, and  (iv) Buyer Sub to execute one
or more  counterparts  of  this Agreement  and  to  deliver at  least  one  such
counterpart so executed to Safety Fund, whereupon Buyer Sub shall become a party
to and be bound by this Agreement.

                          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 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
 
                                      A-36
<PAGE>
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.

    contemplated by this 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,  authorization  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

    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

                                      A-37
<PAGE>
    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:
 
           (1) The Merger, when consummated in accordance with the terms hereof,
               either  will constitute  a reorganization  within the  meaning of
       Section 368(a) of the Code or will be treated as part of a reorganization
       within the meaning of Section 368(a) of the Code,
 
           (2) The exchange of Safety Fund Common Stock to the extent  exchanged
               for  Buyer Common Stock will not give rise to recognition of gain
       or loss for  federal income tax  purposes to the  shareholders of  Safety
       Fund,

               fractional  shares deemed received for  tax purposes) by a Safety
       Fund shareholder will be the same as the basis of the Safety Fund  Common
       Stock surrendered pursuant to the Merger in exchange therefor, and

       surrendered in exchange therefor, PROVIDED  the Safety Fund Common  Stock
       surrendered is held as a capital asset at the Effective Time.
 
        Each  of Buyer  and Safety  Fund shall  provide Arnold  & Porter  with a
    letter setting forth  the facts,  assumptions and  representations on  which
    Arnold & Porter may rely in rendering its opinion.

    warranties to be  so true  and correct  constitute, individually  or in  the
    aggregate,  a Material  Adverse Effect  on Safety  Fund and  the Safety Fund
    Subsidiaries, taken as  a whole;  and Safety  Fund shall  have delivered  to
    Buyer  a  certificate of  Safety Fund  to  such effect  signed by  the Chief

       Closing Date, from Foley, Hoag & Eliot, counsel to Safety Fund as to such
    matters as Buyer  may reasonably  request with respect  to the  transactions

       obtained any and all material permits, authorizations, consents, waivers,
    clearances  or approvals required for the  lawful consummation of the Merger

       Devine, Millimet & Branch, counsel to  Buyer, dated the Closing Date,  as

    Date may be extended until April 5,  1997 by either party by written  notice
    to  the other party (given  not later than December  5, 1996) if the Closing

    circumstances  in  which  neither  party has  the  right  to  terminate this

    transactions contemplated by  this Agreement  and such vote  shall not  have
    been sufficient to approve such transactions;
 
       (e) By  either Safety Fund or  Buyer if final action  has been taken by 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

           hereof.

Agreement  pursuant  to  any provision  of  Section 10.1,  this  Agreement shall
forthwith become void and have no further force, except that (i) the  provisions
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

provision of this Agreement.

    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

    hereunder  unless any such default was intentionally caused by such officer,
    agent or director.
 
    10.3  EXPENSES.   Except as provided in  Section 10.2(b) 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
incurring  such  costs and  expenses, PROVIDED,  HOWEVER,  that the  Expenses of
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
rights  under Section  10.2 hereof,  including but not  limited to  the right to
recover any  liability  or  damages  arising out  of  the  other  party's  gross
negligence or wilful breach of this Agreement.
 
    10.4   AMENDMENT, EXTENSION AND  WAIVER.  Subject to  applicable law, at any

Agreement, (b) extend the time for the performance of any of the obligations  or

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 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;
 
                                      B-1
<PAGE>
        (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
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-2
<PAGE>
    (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:
 
    (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
 
                                      B-3
<PAGE>
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  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
 
                                      B-4
<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 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
 
                                      B-5
<PAGE>
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.
 
    IN WITNESS WHEREOF,  each of  the parties  hereto has  executed this  Option
Agreement as of the day and year first written above.

The Board of Directors:
 
    You  have requested our opinion as to the fairness from a financial point of
view to the shareholders of The  Safety Fund Corporation ("Safety Fund") of  the
consideration  to be paid to the shareholders  of Safety Fund in connection with
the proposed acquisition of Safety Fund by CFX Corporation ("CFX"), pursuant  to
the  Agreement and Plan of Merger (the "Merger Agreement") dated January 5, 1996
by and between Safety Fund and CFX.  Pursuant to the Merger Agreement, CFX  will
form  a wholly owned subsidiary, which will  be merged with and into Safety Fund
(the "Merger").
 
    As is more precisely set forth in the Merger Agreement, upon consummation of
the Merger, each outstanding share of the common stock of Safety Fund, par value
$5.00 per share ("Safety Fund Common  Stock"), except for any dissenting  shares
and  except for shares  held by CFX and  its subsidiaries or  by Safety Fund (in
both cases, other than  shares held in  a fiduciary capacity or  as a result  of
debts previously contracted), will be converted into and exchangeable for either
1.70 shares, in a pooling accounting transaction (the "Pooling Exchange Ratio"),
subject  to  certain  adjustments,  or  1.52  shares  in  a  purchase accounting
transaction (the "Purchase Exchange Ratio"), subject to certain adjustments,  of
the common stock, par value $0.666 per share of CFX ("CFX Common Stock").
 
    In  addition, upon consummation  of the Merger,  each then outstanding stock
option to purchase Safety Fund Common  Stock ("Safety Fund Option") pursuant  to
the  Safety  Fund  1984  and  1994  Stock  Option  Plans,  whether  or  not then
exercisable, will be assumed by CFX. Each  Safety Fund Option so assumed by  CFX
will  continue to  have, and be  subject to,  the same terms  and conditions set
forth in the Safety  Fund Stock Option Plan  immediately prior to the  effective
time  of the Merger, except that (i) each Safety Fund Option will be exercisable
(when vested) for that number of whole  shares of CFX Common Stock equal to  the
product  of  that number  of  shares of  Safety Fund  Common  Stock that  may be
purchased pursuant  to the  Safety  Fund Option,  multiplied by  the  applicable
Exchange  Ratio,  provided  that  any  fractional  shares  resulting  from  such
multiplication will be  rounded down to  the nearest whole  share; and (ii)  the
exercise  price per share of CFX Common  Stock that may be purchased pursuant to
the Safety Fund Option will  be equal to the  Safety Fund Option exercise  price
per  share, divided by the applicable Exchange  Ratio, rounded up to the nearest
cent.
 
    The reader is urged to carefully read all the terms of the Merger Agreement,
which is reproduced in its entirety elsewhere in the Proxy Statement.

negotiations leading to the proposed Transaction with CFX. In the course of  our
role as financial advisor to
 
                                      C-1
<PAGE>
Safety  Fund in connection  with the Transaction  we have received  fees for our
services and  will  receive additional  fees  contingent on  the  occurrence  of
certain  defined events. We will receive a  fee in connection with the rendering
of this opinion. In the  ordinary course of our business,  we may, from time  to
time,  trade the  equity securities  of Safety  Fund in  our capacity  as a NASD
market maker or of CFX in our capacity as a broker dealer, for our own  account,
for  the accounts of our customers and  for the accounts of individual employees
of McConnell, Budd & Downes, Inc. Accordingly we may, from time to time, hold  a
long or short position in the equity securities of either Safety Fund or CFX.
 
    In  arriving at our opinion, we have reviewed the Merger Agreement and Proxy
Statement-Prospectus in  substantially the  form  to be  mailed to  Safety  Fund
shareholders.  We have also reviewed  publicly available business, financial and
shareholder information relating  to Safety Fund  and its subsidiaries,  certain
publicly  available financial information relating  to CFX and certain financial
information relating to Safety Fund provided  by Safety Fund management as  well
as  certain financial information relating to CFX provided by CFX management. In
addition, we have reviewed certain other information, including internal reports
and  documents  of  Safety  Fund  and  certain  management  prepared   financial
information  provided to us  by CFX. We  have also met  with and had discussions
with members of the senior management of each of Safety Fund and CFX to  discuss
their  past  and current  business operations,  current financial  condition and
future  prospects,  including,  in  the  case  of  CFX,  other  pending   merger
transactions.  In connection  with the  foregoing, we  have reviewed  the annual
reports to shareholders and annual  report on Form 10-K  of Safety Fund for  the
fiscal  years ended December  31, 1993 and 1994  and in draft  form for 1995. We
have similarly reviewed the annual reports  of CFX for the calendar years  ended
December 31, 1992, 1993, 1994 and, in draft form annual report for 1995. We have
reviewed  and studied  the historical  stock prices  and trading  volumes of the
common stock of CFX as well as the terms and conditions of 27 recent acquisition
transactions  involving  publicly   traded  financial  institutions   conducting
business in the northeast and compared six of those transactions to the proposed
acquisition  of Safety Fund by CFX. We  also considered the current state of and
future  prospects  for  the  economy  of  New  Hampshire  and  the  economy   of
Massachusetts generally and the relevant market areas for CFX and Safety Fund in
particular.   We  have   also  conducted   such  other   studies,  analyses  and
investigations as we deemed appropriate under the circumstances surrounding this
proposed transaction.
 
    In the course of our review and analysis we considered, among other  things,
such   topics  as  relative  capitalization,  capital  adequacy,  profitability,
availability of non-interest  income, relative  asset quality,  adequacy of  the
reserve for loan losses and the composition of the loan portfolio of each of CFX
and  Safety Fund. We also considered  management's estimates of cost savings and
revenue enhancements which might result from  a consolidation of CFX and  Safety
Fund. In the conduct of our review and analysis we have relied upon and assumed,
without independent verification, the accuracy and completeness of the financial
information  provided  to  us  by  CFX and  Safety  Fund  or  otherwise publicly
obtainable. In reaching our opinion, we have not assumed any responsibility  for
the  independent  verification of  such information  nor  have we  completed any
independent valuation or appraisal  of any of the  assets or the liabilities  of
either  CFX  or Safety  Fund nor  have we  obtained from  any other  source, any
appraisals of the assets or  liabilities of either CFX  or Safety Fund. We  have
also relied on the management of Safety Fund as to the reasonableness of various
financial and operating forecasts, cost savings estimates and of the assumptions
on which they are based, which were provided to us for use in our analyses.
 
    In  the course of rendering  this opinion, which is  being rendered prior to
receipt of certain required  regulatory approvals necessary before  consummation
of  the Transaction, we have  assumed that no conditions  will be imposed by any
regulatory agency in connection with its  approval of the Transaction that  will
have  a  material adverse  effect on  the results  of operations,  the financial
condition or the prospects of CFX following consummation of the Transaction.

    Based upon and subject to the foregoing,  it is our opinion, that as of  the
date  of this letter, the Pooling Exchange Ratio and the Purchase Exchange Ratio
are fair to the shareholders of Safety Fund from a financial point of view.
 
                                          Very truly yours,

                      CHAPTER 156B, SECTIONS 85-98 OF THE
                     MASSACHUSETTS BUSINESS CORPORATION LAW
 
SECTION85.  DISSENTING STOCKHOLDER; RIGHT TO DEMAND PAYMENT FOR STOCK; EXCEPTION
 
    A  stockholder in any corporation organized  under the laws of Massachusetts
which shall have duly voted to consolidate or merge with another corporation  or
corporations  under the provisions of sections seventy-eight or seventy-nine who
objects to such consolidation  or merger may demand  payment for his stock  from
the  resulting or surviving corporation and  an appraisal in accordance with the
provisions  of  sections  eighty-six   to  ninety-eight,  inclusive,  and   such
stockholder and the resulting or surviving corporation shall have the rights and
duties  and follow the procedure set forth in those sections. This section shall
not apply to the  holders of any  shares of stock  of a constituent  corporation
surviving  a merger if, as permitted by subsection (C) of section seventy-eight,
the merger did not require  for its approval a vote  of the stockholders of  the
surviving corporation.
 
SECTION86.  SELECTIONS APPLICABLE TO APPRAISAL; PREREQUISITES
 
    If a corporation proposes to take a corporate action as to which any section
of  this chapter provides  that a stockholder  who objects to  such action shall
have the  right to  demand payment  for  his shares  and an  appraisal  thereof,
sections   eighty-seven  to  ninety-eight,  inclusive,  shall  apply  except  as
otherwise specifically  provided  in any  section  of this  chapter.  Except  as
provided in sections eighty-two and eighty-three, no stockholder shall have such
right  unless (1) he files with the corporation before the taking of the vote of
the shareholders on  such corporate  action, written objection  to the  proposed
action stating that he intends to demand payment for his shares if the action is
taken and (2) his shares are not voted in favor of the proposed action.
 
SECTION87.  STATEMENT OF RIGHTS OF OBJECTING STOCKHOLDERS IN NOTICE OF MEETING;
FORM
 
    The  notice of  the meeting  of stockholders at  which the  approval of such
proposed action is to be considered shall  contain a statement of the rights  of
objecting  stockholders. The giving of such notice shall not be deemed to create
any rights  in any  stockholder receiving  the same  to demand  payment for  his
stock,  and the directors  may authorize the  inclusion in any  such notice of a
statement of opinion by the management  as to the existence or non-existence  of
the  right of the stockholders  to demand payment for  their stock on account of
the proposed corporate action. The notice may  be in such form as the  directors
or officers calling the meeting deem advisable, but the following form of notice
shall be sufficient to comply with this section:
 
    "If  the action proposed is approved by  the stockholders at the meeting and
effected by the corporation, any stockholder (1) who files with the  corporation
before  the taking of the vote on the approval of such action, written objection
to the proposed action stating that he intends to demand payment for his  shares
if  the action  is taken and  (2) whose  shares are not  voted in  favor of such
action has or may have the right to demand in writing from the corporation  (OR,
IN THE CASE OF A CONSOLIDATION OR MERGER, THE NAME OF THE RESULTING OR SURVIVING
CORPORATION  SHALL BE INSERTED), within twenty days after the date of mailing to
him of notice in writing that the corporate action has become effective, payment
for his shares and an appraisal of  the value thereof. Such corporation and  any
such stockholder shall in such cases have the rights and duties and shall follow
the  procedure set forth in sections 88 to 98, inclusive, of Chapter 156B of the
General Laws of Massachusetts."
 
SECTION88.  NOTICE OF EFFECTIVENESS OF ACTION OBJECTED TO
 
    The corporation  taking  such  action,  or  in  the  case  of  a  merger  or
consolidation  the surviving  or resulting  corporation, shall,  within ten days
after the date  on which  such corporate  action became  effective, notify  each
stockholder  who filed a  written objection meeting  the requirements of section
eighty-six and whose  shares were not  voted in  favor of the  approval of  such
action,  that the action approved at the  meeting of the corporation of which he
is a stockholder has become effective. The
 
                                      D-1
<PAGE>
giving of  such  notice  shall  not  be deemed  to  create  any  rights  in  any
stockholder receiving the same to demand payment for his stock. The notice shall
be  sent by registered  or certified mail,  addressed to the  stockholder at his
last known address as it appears in the records of the corporation.
 
SECTION89.  DEMAND FOR PAYMENT; TIME FOR PAYMENT
 
    If within twenty days after the date of mailing of a notice under subsection
(E) of section eighty-two,  subsection (F) of  section eighty-three, or  section
eighty-eight,  any stockholder to whom the corporation was required to give such
notice shall demand in  writing from the corporation  taking such action, or  in
the  case  of  a  consolidation  or  merger  from  the  resulting  or  surviving
corporation, payment for his  stock, the corporation upon  which such demand  is
made  shall pay to him the fair value  of his stock within thirty days after the
expiration of the period during which such demand may be made.
 
SECTION90.  DEMAND FOR DETERMINATION OF VALUE; BILL IN EQUITY; VENUE
 
    If during the period of thirty days provided for in section eighty-nine  the
corporation  upon which such  demand is made and  any such objecting stockholder
fail to  agree as  to the  value of  such stock,  such corporation  or any  such
stockholder  may  within four  months after  the  expiration of  such thirty-day
period demand a determination of  the value of the  stock of all such  objecting
stockholders by a bill in equity filed in the superior court in the county where
the  corporation in which such  objecting stockholder held stock  had or has its
principal office in the commonwealth.
 
SECTION91.  PARTIES TO SUIT TO DETERMINE VALUE; SERVICE
 
    If the bill is filed by the corporation, it shall name as parties respondent
all stockholders who have  demanded payment for their  shares and with whom  the
corporation  has not reached agreement  as to the value  thereof. If the bill is
filed by a stockholder, he shall bring the bill in his own behalf and in  behalf
of  all other stockholders who  have demanded payment for  their shares and with
whom the corporation  has not  reached agreement as  to the  value thereof,  and
service  of the bill shall be made upon  the corporation by subpoena with a copy
of the bill annexed. The corporation shall file with its answer a duly  verified
list  of all such  other stockholders, and such  stockholders shall thereupon be
deemed to have been  added as parties  to the bill.  The corporation shall  give
notice in such form and returnable on such date as the court shall order to each
stockholder  party to the bill by registered or certified mail, addressed to the
last known  address  of  such  stockholder  as  shown  in  the  records  of  the
corporation,  and the court  may order such additional  notice by publication or
otherwise as it deems advisable. Each  stockholder who makes demand as  provided
in  section eighty-nine shall be  deemed to have consented  to the provisions of
this section relating to notice, and the giving of notice by the corporation  to
any  such  stockholder in  compliance with  the order  of the  court shall  be a
sufficient service of process on him. Failure to give notice to any  stockholder
making  demand shall not invalidate the  proceedings as to other stockholders to
whom notice was properly given, and the  court may at any time before the  entry
of a final decree make supplementary orders of notice.
 
SECTION92.  DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION DATE
 
    After  hearing the court shall enter a  decree determining the fair value of
the stock of those stockholders who have become entitled to the valuation of and
payment for their  shares, and shall  order the corporation  to make payment  of
such  value, together  with interest,  if any,  as hereinafter  provided, to the
stockholders entitled thereto upon  the transfer by them  to the corporation  of
the  certificates representing such stock if certificated or, if uncertificated,
upon receipt of an instruction transferring  such stock to the corporation.  For
this  purpose,  the  value of  the  shares shall  be  determined as  of  the day
preceding the date of the vote approving the proposed corporate action and shall
be  exclusive  of  any  element  of  value  arising  from  the  expectation   or
accomplishment of the proposed corporate action.
 
                                      D-2
<PAGE>
SECTION93.  REFERENCE TO SPECIAL MASTER
 
    The  court in  its discretion  may refer  the bill  or any  question arising
thereunder to a special master to hear the parties, make findings and report the
same to the court, all in accordance with the usual practice in suits in  equity
in the superior court.
 
SECTION94.  NOTATION ON STOCK CERTIFICATES OF PENDENCY OF BILL
 
    On  motion the  court may  order stockholder parties  to the  bill to submit
their certificates of stock to the  corporation for the notation thereon of  the
pendency  of the bill and may order the corporation to note such pendency in its
records with  respect to  any  uncertificated shares  held by  such  stockholder
parties,  and may on motion dismiss the bill  as to any stockholder who fails to
comply with such order.
 
SECTION95.  COSTS; INTEREST
 
    The costs of the bill, including reasonable compensation and expenses of any
master appointed by the court,  but exclusive of fees  of counsel or of  experts
retained  by any  party, shall  be determined  by the  court and  taxed upon the
parties to the bill, or any of them, in such manner as appears to be  equitable,
except  that all  costs of  giving notice  to stockholders  as provided  in this
chapter shall be paid by the corporation. Interest shall be paid upon any  award
from the date of the vote approving the proposed corporate action, and the court
may  on application of any interested party  determine the amount of interest to
be paid in the case of any stockholder.
 
SECTION96.  DIVIDENDS AND VOTING RIGHTS AFTER DEMAND FOR PAYMENT
 
    Any stockholder who has demanded payment  for his stock as provided in  this
chapter   shall  not  thereafter  be  entitled  to  notice  of  any  meeting  of
stockholders or to vote such stock for any purpose and shall not be entitled  to
the payment of dividends or other distribution on the stock (except dividends or
other  distributions payable to stockholders of record  at a date which is prior
to the date of the vote approving the proposed corporate action) unless:
 
        1.   A bill  shall not  be filed  within the  time provided  in  section
    ninety;
 
        2.  A bill, if filed, shall be dismissed as to such stockholder; or
 
        3.  Such stockholder shall with the written approval of the corporation,
    or  in the  case of  a consolidation or  merger, the  resulting or surviving
    corporation, deliver to it a written withdrawal of his objections to and  an
    acceptance of such corporate action.
 
    Notwithstanding  the  provisions  of  clauses (1)  to  (3),  inclusive, said
stockholder shall have only the  rights of a stockholder  who did not so  demand
payment for his stock as provided in this chapter.
 
SECTION97.  STATUS OF SHARES PAID FOR
 
    The  shares of the corporation  paid for by the  corporation pursuant to the
provisions of this chapter shall  have the status of  treasury stock, or in  the
case  of a consolidation or merger the shares or the securities of the resulting
or surviving corporation  into which  the shares of  such objecting  stockholder
would  have been converted had  he not objected to  such consolidation or merger
shall have the status of treasury stock or securities.
 
SECTION98.  EXCLUSIVE REMEDY; EXCEPTION
 
    The enforcement by  a stockholder of  his right to  receive payment for  his
shares  in the  manner provided  in this  chapter shall  be an  exclusive remedy
except that this  chapter shall  not exclude the  right of  such stockholder  to
bring  or maintain an appropriate proceeding to obtain relief on the ground that
such corporate action will be or is illegal or fraudulent as to him.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Sections 293-A:8.50-58 of the New Hampshire Business Corporation Act provide
that  a  business  corporation  may  indemnify  directors  and  officers against
liabilities they may  incur in  such capacities provided  certain standards  are
met,  including good faith and  the belief that the  particular action is in the
best interests of the corporation. In general, this power to indemnify does  not
exist in the case of actions against a director or officer by or in the right of
the  corporation  if  the person  entitled  to indemnification  shall  have been
adjudged to be  liable to  the corporation or  in connection  with a  proceeding
charging  improper  personal benefit.  A  corporation is  required  to indemnify
directors and  officers against  expenses they  may incur  in defending  actions
against  them  in  such capacities  if  they  are successful  on  the  merits or
otherwise in the defense of such actions.
 
    The Bylaws of CFX provide for the mandatory indemnification of directors and
officers in accordance with and to the full extent permitted by the laws of  New
Hampshire  as in effect at  the time of such  indemnification. CFX has purchased
directors' and officers' liability insurance covering certain liabilities  which
may  be incurred  by the officers  and directors  of CFX in  connection with the
performance of their duties.
 
ITEM 21.  EXHIBITS AND FINANCIAL STATEMENT SCHEDULES
 
    An index of exhibits appears at  page II-5, which is incorporated herein  by

ITEM 22.  UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes:
 
    1.   To file, during any  period in which offers or  sales are being made, a
post-effective amendment to the Registration Statement:
 
        (a) To  include  any prospectus  required  by Section  10(a)(3)  of  the
    Securities Act;
 
        (b)  To reflect in the prospectus any  facts or events arising after the
    effective  date  of   the  Registration  Statement   (or  the  most   recent
    post-effective  amendment thereof) which, individually  or in the aggregate,
    represent  a  fundamental  change  in  the  information  set  forth  in  the
    Registration  Statement.  Notwithstanding  the  foregoing,  any  increase or
    decrease in the volume of securities  offered (if the total dollar value  of
    securities  offered  would not  exceed that  which  was registered)  and any
    deviation from the low or high  end of the estimated maximum offering  range
    may  be  reflected  in the  form  of  prospectus filed  with  the Commission
    pursuant to Rule  424(b) if,  in the aggregate,  the changes  in volume  and
    price  represent no more than  a 20 percent change  in the maximum aggregate
    offering price set forth in the "Calculation of Registrant Fee" table in the
    effective registration statement; and
 
        (c) To include  any material  information with  respect to  the plan  of
    distribution  not previously disclosed in  the Registration Statement or any
    material change to such information in the Registration Statement;
 
Provided, however, that paragraphs 1(a) and 1(b) do not apply if the information
required to be  included in a  post-effective amendment by  those paragraphs  is
contained  in periodic reports filed by the Registrant pursuant to section 13 or
section 15(d) of  the Exchange  Act that are  incorporated by  reference in  the
Registration Statement.
 
    2.   That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered  therein, and the offering of  such
securities  at that time  shall be deemed  to be the  initial bona fide offering
thereof.
 
                                      II-1
<PAGE>
    3.  To remove from registration  by means of a post-effective amendment  any
of the securities being registered which remain unsold at the termination of the
offering.
 
    The  undersigned  Registrant hereby  undertakes to  respond to  requests for
information that is incorporated  by reference into  the Prospectus pursuant  to
Items  4, 10(b), 11  or 13 of this  Form, within one business  day of receipt of
such request, and  to send  the incorporated  documents by  first-class mail  or
other  equally prompt  means. This  includes information  contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
    The  undersigned  Registrant  hereby   undertakes  that,  for  purposes   of
determining  any liability under the Act, each filing of the Registrant's annual
report pursuant to Section 13(a)  or Section 15(d) of  the Exchange Act that  is
incorporated by reference in this Registration Statement shall be deemed to be a
new  registration statement relating to the  securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial  bona
fide offering thereof.
 
    The  undersigned  Registrant  hereby  undertakes to  supply  by  means  of a
post-effective amendment  all  information  concerning a  transaction,  and  the
company  being  acquired  involved therein,  that  was  not the  subject  of and
included in the Registration Statement when it became effective.
 
    The undersigned Registrant hereby undertakes  as follows: that prior to  any
public  reoffering  of  the securities  registered  hereunder through  use  of a
prospectus which is  a part  of this Registration  Statement, by  any person  or
party  who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering  prospectus will contain the  information
called  for by the  applicable registration form with  respect to reofferings by
persons who may be  deemed underwriters, in addition  to the information  called
for by the other Items of the applicable form.
 
    The  Registrant undertakes that every prospectus  (i) that is filed pursuant
to the  paragraph immediately  preceding,  or (ii)  that  purports to  meet  the
requirements  of section 10(a)(3) of  the Act and is  used in connection with an
offering of  securities subject  to Rule  415, will  be filed  as a  part of  an
amendment  to  the  Registration  Statement  and will  not  be  used  until such
amendment is  effective, and  that, for  purposes of  determining any  liability
under  the Act, each such  post-effective amendment shall be  deemed to be a new
registration statement  relating  to the  securities  offered therein,  and  the
offering  of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    Insofar as  indemnification for  liabilities arising  under the  Act may  be
permitted  to  directors, officers  and  controlling persons  of  the Registrant
pursuant to  the foregoing  provisions, or  otherwise, the  Registrant has  been
informed  that in the opinion of  the Commission such indemnification is against
public  policy  as  expressed   in  the  Securities   Act  and  is,   therefore,
unenforceable.  In  the  event that  a  claim for  indemnification  against such

        RE: AGREEMENT AND PLAN OF MERGER WITH THE SAFETY FUND CORPORATION

Ladies and Gentlemen:


        We have acted as counsel to CFX Corporation (the "Company") in 
connection with the Agreement and Plan of Merger dated as of January 5, 1996 
(the "Agreement") pursuant to which the Company will acquire all of the 
outstanding shares of common stock of The Safety Fund Corporation ("Safety 
Fund") in exchange for the issuance by the Company of up to 
3,200,000 shares of the Company's common stock, $0.66 2/3 par value (the 
"CFX Common Stock").


        Prior to rendering this opinion, we have reviewed such certificates,
documents and records as we have deemed necessary for the purposes hereof,
including the following:

        a.  Copies of the Articles of Agreement and the Bylaws of the Company as
            now in effect;


        b.  The Registration Statement on Form S-4 relating to the CFX Common
            Stock to be issued pursuant to the Agreement being filed with 
            the Securities and Exchange Commission contemporaneously herewith,
            including the exhibits thereto (the "Registration Statement"); and


        c.  Resolutions adopted by the Board of Directors of the Company
            authorizing the execution and delivery of the Agreement and the
            performance of the transactions contemplated therein, including the
            issuance of the CFX Common Stock.

        Based upon the foregoing and such other investigation as we have deemed
necessary, it is our opinion that when (i) the Agreement shall have been
approved by the shareholders of the Company, (ii) the Registration Statement
shall have become effective and (ii) the CFX Common Stock shall have been
issued and delivered to the shareholders of Safety Fund and the consideration
therefor shall have been received by the Company, all in accordance with the 
provisions of the Agreement, the CFX Common Stock will be validly issued, 
fully paid and non-assessable.

Ladies and Gentlemen,


    Reference is made to the information set forth under the heading "PROPOSAL
I -- PROPOSED MERGER -- Certain Federal Income Tax Consequences" contained in
the Proxy Statement, included in the Registration Statement on Form S-4 (the
"Registration Statement"), filed by CFX Corporation ("CFX") with the Securities
and Exchange Commission (the "SEC") in connection with the proposed merger (the
"Merger") of Buyer Sub, a wholly owned subsidiary of CFX with and into the
Safety Fund Corporation ("Safety Fund").  The discussion under that heading, to
the extent it describes the legal opinion of Arnold & Porter, and subject to 
the assumptions and conditions described therein, constitutes our opinion.


    Our opinion is based on the case law, Internal Revenue Code, Treasury
Regulations and Internal Revenue Service rulings as they exist at the date 
hereof.  These authorities are all subject to change, and such change may be 
made with retroactive effect.  We can give no assurance that, after such 
change, our opinion would not be different.  We undertake no responsibility 
to update or supplement our opinion.
