ITEM 5.  OTHER EVENTS.

Change in Real Estate Strategy.
- -------------------------------

         On February 14, 1997, Perini Corporation (the "Company") announced that
it had completed a review of its current real estate strategy following the sale
of shares of newly issued Series B Cumulative  Convertible  Preferred  Stock for
$30,030,000  to  an  investor  group,  as  more  fully  described   below.   The
transaction,  and the  resulting  improvement  in the Company's  balance  sheet,
provides the Company with an  opportunity  to  substantially  improve  liquidity
during 1997 and beyond by changing  its  strategy  with  respect to certain real
estate assets from one of holding them through the development and stabilization
periods to a new strategy of placing  these  properties  on the market now. This
change in strategy  substantially  reduces the  estimated  future cash flow from
these  properties  and has  resulted  in a non-cash  charge  taken in the fourth
quarter  of 1996  in an  aggregate  amount  of  approximately  $80  million.  In
furtherance  of the new  strategy,  Perini  Land and  Development  Company,  the
Company's  wholly owned real estate  development  subsidiary,  recently signed a
letter of intent  to sell its  interest  in the  Resort  at Squaw  Creek,  Squaw
Valley,  California,  to its partner,  HCV Pacific  Investors  III, a California
limited partnership, for a purchase price of $21 million.

Issuance of Series B Preferred Stock.
- -------------------------------------

         On January 17, 1997 (the "Closing Date"), the Company sold an aggregate
of 150,150  shares (the "Shares") of Series B Cumulative  Convertible  Preferred
Stock  ("Series B Preferred  Stock") to an investor  group made up of PB Capital
Partners,  L.P. ("PB  Capital"),  The Common Fund for  Non-Profit  Organizations
("The Common Fund"),  and The Union Labor Life Insurance  Company  ("ULLICO") on
behalf of its Separate  Account P, a commingled fund available for investment by
qualified pension plans. The issuance and sale of the Shares, as well as certain
amendments to the By-Laws of the Company,  were approved by the  stockholders of
the Company at a special  meeting on that date,  and are  described in the proxy
statement  with  respect to such special  meeting  filed by the Company with the
Securities and Exchange Commission on December 17, 1996 (the "Proxy Statement").
The transaction is described in the Proxy Statement under the section  captioned
"Description of Transaction."

         PB  Capital  acquired  92,350  Shares  for  a  total  consideration  of
$18,470,000, which consideration was paid out of funds provided to PB Capital by
its limited  partners.  Richard C. Blum &  Associates,  L.P.  ("RCBA")  acquired
23,300  Shares  on  behalf  of The  Common  Fund  for a total  consideration  of
$4,660,000,  which  consideration  was paid by The Common Fund.  ULLICO acquired
34,500 shares for a total  consideration of $6,900,000,  which consideration was
paid out of funds  provided  to  ULLICO by unit  holders  of  ULLICO's  Separate
Account P.

         The  Shares  were  sold  pursuant  to (i) a  Stock  Purchase  and  Sale
Agreement  dated as of July 24,  1996 by and among the  Company,  PB Capital and
RCBA, as amended,  (ii) a Stock Assignment and Assumption  Agreement dated as of
December 13, 1996 by and among the Company,  PB Capital and ULLICO,  and (iii) a
Stock Assignment and Assumption







Agreement  dated as of January  17, 1997 by and among the  Company,  PB Capital,
RCBA and The Common Fund.

         The Company  amended and restated  its By-Laws as of the Closing  Date.
The By-Law  amendments  are described in the Proxy  Statement  under the section
captioned "Proposal 2:
Approval of Amendment of By-Laws."

         The  holders  of the Series B  Preferred  Stock  designated  Michael R.
Klein, Douglas J. McCarron, and Ronald N. Tutor (the "Designated  Directors") as
their nominees, and they were elected directors of the Company as of January 17,
1997. All three Designated  Directors were appointed to the newly  reconstituted
Executive Committee of the Board of Directors.

         On the Closing  Date,  PB Capital,  David B.  Perini,  Perini  Memorial
Foundation, David B. Perini Testamentary Trust, Ronald N. Tutor and Tutor-Saliba
Corporation  entered into a Voting Agreement.  The Voting Agreement is described
in the Proxy Statement  under the section  captioned  "Voting  Agreement" and is
filed herewith as an exhibit.

         On the Closing Date,  the Company  entered into a  Registration  Rights
Agreement  with PB Capital and ULLICO and a Management  Agreement with Ronald N.
Tutor and  Tutor-Saliba  Corporation.  The  Registration  Rights  Agreement  and
Management  Agreement  are described in the Proxy  Statement  under the sections
captioned   "Registration   Rights   Agreement"  and   "Management   Agreement,"
respectively, and are filed herewith as exhibits.

                              AMENDED AND RESTATED
                          BY-LAWS OF PERINI CORPORATION
                       As amended through January 17, 1997


SECTION 1.        Articles of Organization

         These  by-laws  shall be subject to the  provisions  of the articles of
organization of the corporation, as amended and in effect from time to time.


SECTION 2.        Stockholders

         2.1 Annual  Meeting.  The annual meeting of the  stockholders  shall be
held within six months  after the end of the fiscal year of the  corporation  at
the hour, date and place which is fixed by the board of directors,  the chairman
of the board or the president.

         2.2 Special  Meeting in Place of Annual  Meeting.  If no annual meeting
has been held in accordance with the foregoing provisions,  a special meeting of
the  stockholders  may be held in place  thereof,  and any action  taken at such
special  meeting  shall have the same force and effect as if taken at the annual
meeting and in such case all  references in these by-laws to the annual  meeting
of the stockholders  shall be deemed to refer to such special meeting.  Any such
special meeting shall be called as provided in Section 2.3.

         2.3 Special Meetings. Special meetings of stockholders may be called by
the  chairman  of the  board,  by the  president  or by the board of  directors.
Special meetings shall be called by the clerk, or in case of the death, absence,
incapacity  or  refusal  of  the  clerk,  by any  other  officer,  upon  written
application of one or more stockholders who hold at least forty percent (40%) in
interest of the capital stock entitled to vote at such meeting.

         2.4  Place  of  Meetings.  Meetings  of the  stockholders  may be  held
anywhere  within  the  United  States  at such  place  as  shall be fixed by the
chairman of the board, the president or the directors.  Any adjourned session of
any  meeting of the  stockholders  shall be held at the same city or town as the
initial session, or within Massachusetts, in either case at the place designated
in the vote of adjournment.

         2.5  Notice  of  Meetings.   A  written   notice  of  each  meeting  of
stockholders,  stating the place, date and hour and the purposes of the meeting,
shall be given at least ten days before the meeting to each stockholder entitled
to vote  there  at and to each  stockholder  who,  by law,  by the  articles  of
organization or by these by-laws,  is entitled to notice, by leaving such notice
with him or at his  residence  or usual  place of  business,  or by mailing  it,
postage prepaid,  and addressed to such stockholder at his address as it appears
in the records of the corporation. Such notice shall be given by the clerk or an
assistant clerk or by the secretary or an assistant secretary.  No notice of any
meeting of  stockholders  need be given to a stockholder  if a written waiver of
notice, executed before or after the meeting by such






stockholder or his attorney thereunto duly authorized, if filed with the records
of the meeting.

         2.6  Quorum of  Stockholders.  At any  meeting of the  stockholders,  a
quorum  shall  consist  of a  majority  in  interest  of all  stock  issued  and
outstanding  and  entitled  to vote at the  meeting;  except that if two or more
classes or series of stock are  entitled to vote as separate  classes or series,
then in the case of each  such  class or  series a  quorum  shall  consist  of a
majority  in  interest  of  all  stock  of  that  class  or  series  issued  and
outstanding; and except when a larger quorum is required by law, by the articles
of organization  or by these by-laws.  Stock owned directly or indirectly by the
corporation,  if any, shall not be deemed  outstanding  for this  purposes.  Any
meeting may be adjourned  from time to time by a majority of the votes  properly
cast upon the question,  whether or not a quorum is present, and the meeting may
be held as adjourned without further notice.

         2.7  Action  by Vote.  When a  quorum  is  present  at any  meeting,  a
plurality of the votes  properly  cast for election to any office shall elect to
such office,  and a majority of the votes  properly cast upon any question other
than an election to an office  shall decide the  question,  except when a larger
vote is required by law, by the articles of organization or by these by-laws. No
ballot  shall be required  for any election  unless  requested by a  stockholder
present or represented at the meeting and entitled to vote in the election.

         2.8  Voting.   Except  as   otherwise   provided  in  the  articles  of
organization,  stockholders  entitled to vote shall have one vote for each share
of stock entitled to vote held by them of record according to the records of the
corporation.  The corporation shall not, directly or indirectly,  vote any share
of its own stock.

         2.9 Matters to be considered at Annual Meeting. At an annual meeting of
stockholders,  only such business  shall be conducted,  and only such  proposals
shall be acted  upon,  as shall  have been  properly  brought  before the annual
meeting (a) by, or at the  direction of, a majority of the board of directors or
(b) by any  holder of record  (both as of the time  notice of such  proposal  is
given by the  stockholder  as set forth  below and as of the record date for the
annual  meeting in question) of any shares of the  corporation's  capital  stock
entitled to vote at such annual  meeting who complies  with the  procedures  set
forth in this  Section  2.9.  For a proposal  to be properly  brought  before an
annual meeting by a stockholder,  the stockholder  must have given timely notice
thereof in writing to the clerk of the corporation,  and such stockholder or his
representative  must be present in person at the annual meeting. To be timely, a
stockholder's  notice  must be  delivered  to, or mailed  and  received  at, the
principal  executive  offices of the  corporation not less than 75 days nor more
than 180 days prior to the day on which the annual meeting immediately preceding
the  annual  meeting  at which the  proposal  is  proposed  to be acted upon was
initially  convened (the "Anniversary  Date");  provided,  however,  that if the
annual meeting in any year is scheduled to be held on a day which is more than 7
days earlier  than the  Anniversary  Date,  then notice by a  stockholder  to be
timely must be so  delivered or received not later than the close of business on
(a) on the 20th day following the earlier of (i) the day on which such notice of
the date of the  annual  meeting  is  mailed  or (ii)  the day on  which  public
disclosure  of the date of the annual  meeting  is made,  or (b) if such date of
notice or public disclosure occurs more than 75 days prior to the scheduled date
of such meeting, then the later of (i) the 20th day following the first to occur
of such notice or such public disclosure or (ii) the






75th day prior to such scheduled date of such meeting. A stockholder's notice to
the clerk  shall set forth as to each matter the  stockholder  proposes to bring
before the annual meeting (a) a brief  description of the proposal desired to be
brought before the annual  meeting and the reasons for conducting  such business
at the  annual  meeting,  (b)  the  name  and  address,  as they  appear  on the
corporation's  stock transfer books, of the stockholder  proposing such business
and  of the  beneficial  owners  (if  any)  of  the  stock  registered  in  such
stockholder's  name and the name and address of other stockholders known by such
stockholder  to be supporting  such  proposal on the date of such  stockholder's
notice,  (c) the class and number of shares of the  corporation's  capital stock
which are beneficially  owned by the stockholder and such beneficial  owners (if
any) on the date of such  stockholder's  notice  and by any  other  stockholders
known by such  stockholder  to be  supporting  such proposal on the date of such
stockholder's  notice, and (d) any financial interest of the stockholder in such
proposal.

         If  the  board  of  directors,   or  a  designated  committee  thereof,
determines that any stockholder  proposal was not timely made in accordance with
the terms of this Section 2.9, such  proposal  shall not be presented for action
at the annual  meeting in question.  If the board of directors,  or a designated
committee thereof,  determines that the information  provided in a stockholder's
notice does not satisfy the  informational  requirements  of this section in any
material  respect,  the clerk of the  corporation  shall  promptly  notify  such
stockholder  of the  deficiency in the notice.  Such  stockholder  shall have an
opportunity  to cure the deficiency by providing  additional  information to the
clerk  within  such  period  of time,  not to  exceed 5 days  from the date such
deficiency notice is given to the stockholder, as the board of directors or such
committee shall reasonably determine. If the deficiency is not cured within such
period,  or if the board of  directors  or such  committee  determines  that the
additional   information   provided  by  the  stockholder,   together  with  the
information  previously  provided,  does not  satisfy the  requirements  of this
Section 2.9 in any material  respect,  then such proposal shall not be presented
for action at the annual meeting in question.

         Notwithstanding the procedure set forth in the preceding paragraph,  if
neither the board of directors nor such committee  makes a  determination  as to
the  validity of any  stockholder  proposal as set forth  above,  the  presiding
officer of the annual meeting shall  determine and declare at the annual meeting
whether the  stockholder  proposal was made in accordance with the terms of this
Section 2.9. If the presiding officer determines that a stockholder proposal was
made in  accordance  with the terms of this  Section 2.9, he shall so declare at
the annual  meeting.  If the  presiding  officer  determines  that a stockholder
proposal was not made in accordance  with the provisions of this Section 2.9, he
shall so declare at the annual meeting and such proposal shall not be acted upon
at the annual meeting.

         This  provision  shall not prevent the  consideration  and  approval or
disapproval  at the  annual  meeting  of  reports  of  officers,  directors  and
committees of the board of directors,  but in connection  with such reports,  no
new business  shall be acted upon at such annual  meeting  except in  accordance
with the provisions of this Section 2.9.

         2.10 Action by Writing.  Any action to be taken by stockholders  may be
taken  without a meeting  if all  stockholders  entitled  to vote on the  matter
consent to the action by a writing  filed with the  records of the  meetings  of
stockholders.  Such  consent  shall be treated  for all  purposes as a vote at a
meeting.







         2.11 Proxies.  Stockholders  entitled to vote may vote either in person
or by proxy.  Any proxy must be in  writing  and must be filed with the clerk or
other person  responsible to record the  proceedings of the meeting before being
voted.  No proxy  dated more than six months  before the meeting  named  therein
shall be valid.  Unless  otherwise  specifically  limited by their  terms,  such
proxies shall  entitle the holders  thereof to vote at the meeting named therein
and at any  adjournment  of such meeting,  but no proxy shall be valid after the
final  adjournment  of such  meeting.  A proxy with respect to stock held in the
name of two or more  persons  shall  be  valid  if  executed  by any one of them
unless,  at or prior to  exercise  of the  proxy,  the  corporation  receives  a
specific written notice to the contrary from any one of them. A proxy purporting
to be executed by or on behalf of a  stockholder  shall be deemed  valid  unless
challenged  at or prior to its  exercise  and the burden of  proving  invalidity
shall rest on the challenger.

         2.12  Postponement  or  Adjournment of Annual or Special  Meeting.  The
board of  directors  acting  by  resolution  may  postpone  and  reschedule  any
previously  scheduled annual or special meeting of  stockholders.  The presiding
officer at all annual or special meetings of stockholders  shall have the power,
among other  things,  to adjourn such meeting at any time and from time to time,
subject to Section 2.6. The order of business and all other matters of procedure

SECTION 3.        Board of Directors

         3.1      Election, Number and Qualification.

                  (a) During any time that the corporation is subject to Section
50A of Chapter 156B of the  Massachusetts  General Laws ("Section 50A"), (1) the
number of directors  (which shall not be less than three or less than the number
of  stockholders,  if less than three)  shall be  determined  and  increased  or
decreased  from time to time only by vote of the board of directors  and (2) the
directors,  other than  those who may be elected by the  holders of any class or
series of  preferred  stock,  shall be  classified  with respect to the term for
which they generally hold office, pursuant to the terms of Section 50A.

                  (b) During  any time that the  corporation  is not  subject to
Section 50A, (1) the number of directors  shall be  determined  and increased or
decreased from time to time only by vote of the board of directors,  except that
the board of  directors  may be enlarged  by the  stockholders  at any  meeting,
provided that the vacancies  created by such an  enlargement  shall be filled in
accordance  with Section 6 and (2) except as  otherwise  provided by law, by the
articles of organization or by these by-laws,  directors shall hold office until
the next annual meeting of  stockholders  and until their  successors are chosen
and qualified.

                  (c) No  director  need be a  stockholder.  No  decrease in the
number of directors shall shorten the term of any incumbent Director.

         3.2 Powers;  Issuance of Stock.  Except as reserved to the stockholders
by law, by the articles of organization or by these by-laws, the business of the
corporation  shall be managed by the directors,  who shall have and may exercise
all the powers of the  corporation.  In  particular,  and without  limiting  the
generality of the foregoing,  the board of







directors  shall have the  authority  to issue or reserve for issue from time to
time the whole or any part of the capital stock of the corporation  which may be
authorized  from  time to  time,  to such  persons  or  organizations,  for such
consideration,  whether cash, property,  services or expenses, and on such terms
as the board of  directors  may  determine,  including  without  limitation  the
granting of options,  warrants,  or  conversion  or other rights to subscribe to
said capital stock.

         3.3 Executive Committee and Other Committees.  The directors, by a vote
of a majority of the directors then in office,  shall elect from their number an
Executive Committee composed of five members and may elect such other committees
the directors shall determine,  and delegate to them authority to act as and for
the board to the extent permitted by law and as provided herein.

                  (a) Neither the board of directors nor the  corporation  shall
take any of the following  actions  without the prior  approval of a majority of
the members of the  Executive  Committee:  (i) any borrowing or guarantee by the
corporation  exceeding $15 million;  (ii) except for issuances of stock or stock
options pursuant to the corporation's  incentive  compensation plan or programs,
any  issuance  of  stock  (whether  common  or  preferred,   whether  voting  or
non-voting,  whether junior or senior to the  corporation's  Series B Cumulative
Convertible  Preferred  Stock) other than common stock of the  corporation in an
amount not  exceeding  five  percent (5%) of the issued and  outstanding  common
stock  on  January  17,  1997;  (iii)  any  strategic  alliance  (other  than  a
construction joint venture) involving a capital commitment exceeding $5 million;
(iv)  any  asset  sale or lease  exceeding  $5  million  (other  than  equipment

of the Preferred Share Purchase  Rights,  of the kind authorized and declared on
September 23, 1988 and  distributed by the  corporation in September 1988 as the
same  have been  amended  on or  before  January  17,  1997  ("Rights"),  or the
preferred stock of the corporation issuable upon the exercise of such Rights, or
any amendment of the Shareholder Rights Agreement by and between the corporation
and State Street Bank and Trust Company,  as Rights Agent, dated as of September
23, 1988,  as amended  through  January 17, 1997;  and (vi) any  termination  of
(other  than a  termination  on  expiration)  or  amendment  to  the  management
agreement among the corporation,  Tutor-Saliba  Corporation and Ronald N. Tutor;
provided,  however,  that for  purposes of this  Section  3.3(a) of the by-laws,
approval of the  Executive  Committee  shall not be required for any decision by
the board of directors to redeem the Series B Cumulative  Convertible  Preferred
Stock  pursuant  to  Section  6(a) of the  terms  thereof.  Notwithstanding  the
foregoing  sentence,  the board of directors of the  corporation may take any of
the actions specified in the preceding  sentence if, after having consulted with
and considered the advice of outside  counsel,  it has reasonably  determined in
good faith that the failure of the board to take such action  would be likely to
cause  the  members  of such  board  to  breach  their  fiduciary  duties  under
applicable law.

                  (b) The  Executive  Committee  shall  make the  rules  for the
conduct of its  business;  provided,  however,  that it shall have no  permanent
chairman,  shall  report its actions to the board of  directors,  and shall keep
minutes of its meetings.  Other committees  created and elected by the directors
may  exercise  such powers other than those  powers  delegated to the  Executive
Committee,  as the  directors  determine.  Except as the directors may otherwise
determine,  any such other  committee  may make the rules for the conduct of its
business, but unless otherwise provided by the directors or waived, its business
shall be conducted,  or its







actions taken in as nearly as may be the same manner as is provided for by these
by-laws with respect to meetings or for the conduct of business or the taking of
action by the directors.

                  (c) All members of such  committees  shall hold such  offices,
and all such  committees  shall  exist,  solely at the  pleasure of the board of
directors; provided, however, that the Executive Committee may not be disbanded,
reorganized,  or reconstituted  without the prior written approval of a majority
of the members of the Executive  Committee as  constituted  prior to such change
(if the holders of the Series B Cumulative Convertible Preferred Stock then have
the right to designate more than one member of the Executive  Committee pursuant
to the Certificate of Vote  establishing  such series,  including the members so
designated  by the  holders of the  Series B  Cumulative  Convertible  Preferred
Stock); provided further, however, that the board shall not take any action that
would result in there being fewer members of the Executive Committee  designated
by the holders of the Series B Cumulative  Convertible Preferred Stock than such
holders  are  entitled  to  designate   pursuant  to  the  Certificate  of  Vote
establishing  such series.  The board shall have the power to rescind any action
of any committee  (other than  decisions or actions of the  Executive  Committee
pursuant  to Section  3.3(a) or 4.5  hereof);  provided,  however,  that no such
rescission shall have any retroactive effect.

         3.4 Meetings.  Regular  meetings of the directors,  including the first
meeting of the board  following the annual meeting of the  stockholders,  may be
held  without  call or notice at such places and at such times as the  directors
may from time to time  determine,  provided  that  notice  of the first  regular
meeting  following any such  determination  shall be given to absent  directors.
Special  meetings  of the  directors  may be held at any time  and at any  place
designated  in the call of the meeting when called by the chairman of the board,
the  vice  chairman  of  the  board,  the  president,  the  treasurer  or by the
directors,  notice  thereof  being  given to each  director  by the  clerk or an
assistant clerk or by the secretary or an assistant  secretary or by the officer
or the directors  calling the meeting.  Directors may participate in meetings of
the  board  of   directors   by  means  of   conference   telephone  or  similar
communications  equipment by means of which all directors  participating  in the
meeting  can hear each  other,  and  participation  in a meeting  in  accordance
herewith shall constitute presence in person at such meeting.

3.5 Notice.  It shall be sufficient  notice to a director to send notice by mail
at least  forty-eight hours or by telegram at least twenty-four hours before the
meeting  addressed  to him at his  usual or last  known  business  or  residence
address or to give notice to him in person or by telephone at least  twenty-four
hours before the meeting.  Notice of a meeting need not be given to any director
if a written waiver of notice,  executed by him before or after the meeting,  is
filed with the  records of the  meeting,  or to any  director  who  attends  the
meeting  without  protesting  prior thereto or at its  commencement  the lack of
notice to him. Neither notice of a meeting nor a waiver of a notice need specify
the purposes of the meeting.

         3.6 Quorum. At any meeting of the directors a majority of the directors
then in office shall constitute a quorum. Any meeting may be adjourned from time
to time by a  majority  of the votes  cast upon the  question,  whether or not a
quorum is  present,  and the meeting may be held as  adjourned  without  further
notice.






         3.7 Action by Vote. When a quorum is present at any meeting, a majority
of the  directors  present  may take any  action  except  when a larger  vote is
required by law, by the articles of organization or by these by-laws.

         3.8 Action by Writing.  Any action required or permitted to be taken at
any meeting of the directors may be taken without a meeting if a written consent
thereto is signed by all the  directors  and such written  consent is filed with
the records of the meetings of the directors.  Such consent shall be treated for
all purposes as a vote at a meeting.

         3.9 Nomination of Directors.  Nominations of candidates for election as
directors of the corporation at any annual meeting of  stockholders  may be made
(a) by, or at the  direction  of, a majority of the board of directors or (b) by
any holder of record (both as of the time notice of such  nomination is given by
the  stockholder  as set forth  below and as of the  record  date for the annual
meeting in question) of any shares of the  corporation's  capital stock entitled
to vote at such  meeting  who  complies  with the  procedures  set forth in this
Section  3.9.  Any  stockholder  who  seeks to make  such a  nomination,  or his
representative,  must be present in person at the annual  meeting.  Only persons
nominated in accordance  with the procedures set forth in this Section 3.9 shall
be eligible for election as directors at an annual meeting of stockholders.

         Nominations,  other  than those  made by, or at the  direction  of, the
board of  directors,  shall be made  pursuant to timely notice in writing to the
clerk of the  corporation  as set forth in this  Section  3.9.  To be timely,  a
stockholder's  notice  shall be  delivered  to, or mailed and  received  at, the
principal  executive  offices of the  corporation not less than 75 days nor more
than 180 days prior to the  Anniversary  Date;  provided,  however,  that if the
annual meeting in any year is scheduled to be held on a day which is more than 7
days earlier than the Anniversary Date then notice by a stockholder to be timely
must be so delivered or received not later than the close of business on (a) the
20th day  following  the earlier of (i) the day on which such notice of the date
of the annual  meeting is mailed or (ii) the day on which public  disclosure  of
the date of the annual  meeting is made, or (b) if such date of notice or public
disclosure occurs more than 75 days prior to the scheduled date of such meeting,
then the later of (i) the 20th day  following  the first to occur of such notice
or such public  disclosure or (ii) the 75th day prior to such  scheduled date of
such meeting.  Such  stockholder's  notice shall set forth (a) as to each person
whom the  stockholder  proposes to nominate  for  election or  re-election  as a
director  (i) the name,  age,  business  address and  residence  address of such
person, (ii) the principal  occupation or employment of such person for the past
five years and (iii) the class and number of shares of the corporation's capital
stock  which  are  beneficially  owned  by  such  person  on the  date  of  such
stockholder  notice and (b) as to the stockholder giving the notice (i) the name
and address,  as they appear on the corporation's  stock transfer books, of such
stockholder  and of the  beneficial  owners (if any) of the stock  registered in
such  stockholder's name and the name and address of other stockholders known by
such   stockholder  to  be  supporting   such  nominees  on  the  date  of  such
stockholder's   notice   and  (ii)  the  class  and  number  of  shares  of  the
corporation's capital stock which are beneficially owned by such stockholder and
such beneficial  owners (if any) on the date of such  stockholder  notice and by
any other  stockholders known by such stockholder to be supporting such nominees
on the  date  of  such  stockholder  notice.  At the  request  of the  board  of
directors,  any  person  nominated  by,  or at the  direction  of,  the board of
directors  for election as a director at an annual  meeting shall furnish to the
clerk of the corporation that






information  required to be set forth in a  stockholder's  notice of  nomination
which pertains to the nominee.

         No person  shall be elected by the  stockholders  as a director  of the
corporation unless nominated in accordance with the procedures set forth in this
Section  3.9. If the board of  directors,  or a  designated  committee  thereof,
determines  that any  stockholder  nomination  was not timely made in accordance
with the terms of this Section such  nomination  shall not be  considered at the
annual meeting in question. If the board of directors, or a designated committee
thereof, determines that the information provided in a stockholder's notice does
not satisfy the  informational  requirements of this Section 3.9 in any material
respect,  the clerk of the corporation shall promptly notify such stockholder of
the deficiency in the notice. Such stockholder shall have an opportunity to cure
the  deficiency  by providing  additional  information  to the clerk within such
period of time,  not to exceed 5 days  from the date such  deficiency  notice is
given to the  stockholder,  as the board of  directors or such  committee  shall
determine. If the deficiency is not cured within such period, or if the board of
directors  or  such  committee   reasonably   determines   that  the  additional
information   provided  by  the  stockholder,   together  with  the  information
previously  provided,  does not satisfy the  requirements of this Section 3.9 in
any material  respect,  such  nomination  shall not be  considered at the annual
meeting in question.

         Notwithstanding the procedure set forth in the preceding paragraph,  if
neither the board of directors nor such committee  makes a  determination  as to
the  validity  of any  nominations  by a  stockholder  as set forth  above,  the
presiding  officer of the annual  meeting  shall  determine  and  declare at the
annual  meeting  whether a nomination  was made in accordance  with the terms of
this Section 3.9. If the presiding officer determines that a nomination was made
in  accordance  with the terms of this  Section  3.9, he shall so declare at the
annual meeting.  If the presiding  officer  determines that a nomination was not
made in  accordance  with the terms of this  Section 3.9, he shall so declare at
the annual meeting and such nomination shall be disregarded.

vice president and by the treasurer or an assistant  treasurer.  Such signatures
may be  facsimiles  if the  certificate  is signed by a  transfer  agent or by a
registrar,  other than a director,  officer or employee of the  corporation.  In
case any officer






who has signed or whose facsimile  signature has been placed on such certificate
shall have ceased to be such officer before such  certificate is issued,  it may
be issued by the corporation  with the same effect as if he were such officer at
the time of its issue.  Every  certificate for shares of stock which are subject
to any restriction on transfer and every certificate issued when the corporation
is authorized to issue more than one class or series of stock shall contain such
legend with respect thereto as is required by law.

articles of organization or by these by-laws,  the corporation shall be entitled
to treat the  record  holder of stock as shown on its books as the owner of such

receive  notice and to vote with respect  thereto,  regardless  of any transfer,
pledge  or  other  disposition  of  such  stock,  until  the  shares  have  been
transferred on the books of the corporation in accordance with the  requirements
of these by-laws.

         It shall be the duty of each  stockholder to notify the  corporation of
his post office address.

         8.3 Record Date and Closing  Transfer  Books.  The directors may fix in
advance a time,  not more than  sixty  days  before  the date of any  meeting of
stockholders  or  the  date  for  payment  of  any  dividend  or  making  of any
distribution  to stockholders or the last day on which the consent or dissent of
stockholders  may be effectively  expressed for any purpose,  as the record date
for  determining the  stockholders  having the right to notice of and to vote at
such meeting and any  adjournment  thereof or the right to receive such dividend
or distribution or the right to give such consent or dissent. In such case, only
stockholders   of  record  on  such   record   date  shall   have  such   right,
notwithstanding  any transfer of stock on the books of the corporation after the
record date.  Without fixing such record date, the directors may for any of such
purposes close the transfer books for all or any part of such period.








SECTION 9.        Indemnification of Directors and Officers

         9.1  General.  Subject  to  the  provision  of  this  Section  and  any
limitations  imposed by law, the  corporation  shall indemnify its directors and
officers against all expenses incurred by them in connection with any proceeding
in which they are involved by reason of their serving in such capacities  except
that (i) no  indemnification  shall be provided for any director or officer with
respect  to any matter as to which he shall  have been  adjudicated  not to have
acted in good faith and in the reasonable belief that his action was in the best
interests of the corporation,  or with respect to a criminal matter, that he had
reasonable  cause  to  believe  that  his  conduct  was  unlawful,  and  (ii) no
indemnification  shall be provided for any director or officer with respect to a
proceeding by or in the right of the  corporation  in which he is adjudicated to
be liable to the corporation. Such indemnification may be provided to an officer
or director  in  connection  with a  proceeding  in which it is alleged  that he
received an improper  personal benefit by reason of his position,  regardless of
whether  the claim  involves  his  services  in such  capacity,  subject  to the
foregoing  limitation,  unless it shall have been  determined  that an  improper
personal benefit was received by the director or officer.  Except as provided in
Section 9.2,  indemnification  under this Section 9 shall be  authorized in each
case as determined by the board of directors, which may act notwithstanding that
one or more of these  members  are  parties to the  proceeding  in  question  or
otherwise have an interest in such indemnification.

         9.2 Mandatory Indemnification.  Notwithstanding any contrary provisions
of this  Section,  if a director or officer of the  corporation  has been wholly
successful  on the merits in defense of any  proceeding in which he was involved
by  reason  of his  position  or as a result  of his  serving  in such  capacity
(including  the  termination of  investigative  or other  proceedings  without a
finding  of  fault  on the  part  of the  director  of  officer),  he  shall  be
indemnified  by  the  corporation  against  all  expenses  incurred  by  him  in
connection therewith.

         9.3      Definitions.  For purposes of this Section 9:

                  (a) A "director" or "officer"  means any person  serving in an
office filled by  appointment  or election by the directors or the  stockholders
and also  includes (i) a director or officer of the  corporation  serving at the
request of the corporation as a director, officer, employee, trustee, partner or
other agent of another  organization,  (ii) any person who formerly  served as a
director or officer,  and (iii) the heirs or  personal  representatives  of such
persons;

                  (b) "Expenses" means all expenses  (including  attorneys' fees
and disbursements)  actually and reasonably  incurred in defense of a proceeding
or in successfully  seeking  indemnification  under Section 9.2 hereof,  and any
judgments, awards, fines, penalties and reasonable amounts paid in settlement of
a proceeding; and

                  (c) A "proceeding" means any threatened,  pending or completed
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative, and any claim which could be the subject of a proceeding.






         9.4 Advances. Except as limited by law, expenses incurred by a director
or officer in  defending  any  proceeding  in which he is  involved by reason of
serving in such  capacities  may be paid by the  corporation in advance of final
disposition of the proceeding  upon receipt of his written  undertaking to repay
such  amount  if it is  ultimately  determined  that  he is not  eligible  to be
indemnified, which undertaking shall be an unlimited general obligation but need
not be secured and may be accepted  without  regard to the financial  ability of
such persons to make repayment;  provided, that no such advance payment shall be
made  if it is  determined  by  the  board  of  directors  on the  basis  of the
circumstances  known at the  time  (without  further  investigation)  that  said
director or officer will  ultimately be ineligible to be indemnified  under this
Section 9.

         9.5 Settlement  Proceedings.  If a proceeding is compromised or settled
in a manner which imposes a liability or obligation  upon a director or officer,
(i) no indemnification  shall be provided to him with respect to a proceeding by
or in the right of the corporation  unless the board of directors  determines in
its discretion that indemnification is appropriate under the circumstances,  and
(ii) no indemnification  shall be provided to him with respect to any other type
of proceeding  if it is determined by the board of directors  that said director
or  officer  is  ineligible  to  be  indemnified   under  this  Section  9.  The
determination  by the board of directors in each case shall be made on the basis
of the circumstances know to it at that time without further investigation.

         9.6  Insurance.  The  corporation  shall  have  power to  purchase  and
maintain insurance on behalf of any director,  officer, employee or agent of the
corporation  against any  liability or cost incurred by him in any such capacity
or arising out of his status as such,  whether or not the corporation would have
the power to indemnify him against such liability or cost.

         9.7 Employee  Benefit Plans. If the corporation or any of its directors
or officers  sponsors,  undertakes or incurs any  responsibility  as a fiduciary
with respect to an employee benefit plan, then, for purposes of  indemnification
of such person under this Section (i) a "director" or "officer"  shall be deemed
to include any director or officer of the  corporation who serves at its request
in any capacity  with respect to said plan,  (ii) such director or officer shall
be deemed not to have  failed to have acted in good faith and in the  reasonable
belief that his action has in the best interests of the  corporation if he acted
in good  faith and in the  reasonable  belief  that his  action  was in the best
interest of the participants or beneficiaries of said plan, and (iii) "expenses"
shall be deemed to include any taxes or penalties  assessed on such  director or
officer with respect to said plan under applicable law.

         9.8 Other  Provisions.  The  provisions  of this Section 9 shall not be
construed to limit the power of the  corporation  to  indemnify  its officers or
directors to the full extent  permitted by law and enter specific  agreements or
arrangements for this purpose. In addition,  the corporation shall have power to
indemnify  any of its agents or employees  who are not  directors or officers on
any terms consistent with law which it deems to be appropriate.

         9.9  Amendment.  The  provisions  of this  Section 9 may be  amended or
repealed  by the  stockholders;  however,  no such  amendment  or  repeal  which
adversely  affects the rights






of a  director  of  officer  under  this  Section 9 with  respect to his acts or
omissions  at any time prior to such  amendment  or repeal,  shall  apply to him
without consent.

                     General Laws, Chapter 156B, Section 26


         We, David B. Perini,  President and Richard E. Burnham, Clerk of Perini
Corporation located at 73 Mt. Wayte Avenue,  Framingham,  Massachusetts 01701 do
hereby  certify that at a meeting of the  directors of the  corporation  held on
January 10, 1997, the following vote  establishing and designating a series of a
class of stock and determining  the relative rights and preferences  thereof was
duly adopted:

That  pursuant  to the  authority  vested  in the  Board  of  Directors  of this
Corporation  in  accordance  with the  provisions  of its  Restated  Articles of
Organization,  as amended, a series of Preferred Stock (the "Series B Cumulative
Convertible  Preferred  Stock") of the Corporation be, and it hereby is, created
and that the designation  and amount thereof and the voting powers,  preferences
and relative, participating,  optional and other special rights of the shares of
such series, and the qualifications, limitations and restrictions thereof are as
set forth on Exhibit A hereto.

                                                                       EXHIBIT A

                 SERIES B CUMULATIVE CONVERTIBLE PREFERRED STOCK

         1.  Designation and Amount.  There shall be a series of Preferred Stock
designated as "Series B Cumulative  Convertible  Preferred Stock" and the number
of shares  constituting such series shall be 500,000,  of which 150,150 shall be
issued initially (the date of such issuance,  the "Original Issue Date") and the
remainder  shall be reserved  for  issuance as  dividends  pursuant to Section 3
below.  The  number of  shares  designated  as  shares  of  Series B  Cumulative
Convertible Preferred Stock may be decreased (but not increased) by the Board of
Directors without a vote of stockholders;  provided,  however,  that such number
may not be decreased  without the approval of the holders of 66-2/3% of the then
outstanding shares of Series B Cumulative Convertible Preferred Stock.

         2.  Preemptive  Rights.  Holders  of  shares  of  Series  B  Cumulative
Convertible  Preferred  Stock are not entitled to any preemptive or subscription
rights in respect of any securities of the Corporation.


                                        1



         3.       Dividends.

                  (a) The holders of shares of Series B  Cumulative  Convertible
Preferred  Stock  shall be  entitled  to  receive,  when and as  authorized  and
declared by the Board of Directors  out of funds at the time  legally  available
therefor,  dividends at the Cash Dividend  Rate (defined  below) per annum times
the Liquidation  Preference  (defined below in Section 4(a)) if paid in cash, or
at the In-Kind  Dividend  Rate (defined  below) per annum times the  Liquidation
Preference  if paid in  additional  shares  of Series B  Cumulative  Convertible
Preferred Stock, and no more, which shall be fully cumulative, shall accrue with
respect to any such  share  from the  original  date of  issuance  of such share
without interest and shall be payable quarterly in arrears on March 15, June 15,
September  15  and  December  15 of  each  year  (a  "Dividend  Payment  Date"),
commencing March 15, 1997 (except that if any such date is a Saturday, Sunday or
legal holiday, then such dividend shall be payable on the next day that is not a
Saturday,  Sunday or legal holiday) to holders of record as they appear upon the
stock transfer books of the Corporation on each March 1, June 1, September 1 and
December 1 immediately preceding the payment dates, or such other dates as shall
be  fixed at the  time of the  authorization  and  declaration  by the  Board of
Directors  (or, to the extent  permitted by  applicable  law, a duly  authorized
committee  thereof),  which  date  shall not be less than ten (10) nor more than
sixty (60) days  preceding  the relevant  dividend  payment  date.  For purposes
hereof,   the  term  "legal  holiday"  shall  mean  any  day  on  which  banking
institutions  are  authorized  to close in New  York,  New York.  The  amount of
dividends payable per share of Series B Cumulative  Convertible  Preferred Stock
for each  quarterly  dividend  period  shall be computed by dividing  the annual
dividend  amount by four and shall  include  fractional  shares.  The  amount of
dividends  payable for the initial dividend period and any period shorter than a
full quarterly  period during which shares are outstanding  shall be computed on
the basis of a 360-day  year of twelve  30-day  months and the actual  number of
days  elapsed in the period in which  payable.  No interest  shall be payable in
respect of any dividend payment on the Series B Cumulative Convertible Preferred
Stock or any other Parity Dividend Stock (as  hereinafter  defined) which may be
in arrears.  The "Cash  Dividend Rate" shall be 9 percent per annum if a Special
Default  (defined  below) has occurred and is  continuing at any time during the
applicable  Annual Payment Period (defined  below) or Semiannual  Payment Period
(defined  below),  and shall be 7 percent  per  annum at all  other  times.  The
"In-Kind  Dividend Rate" shall be 12 percent per annum if a Special  Default has
occurred and is  continuing  at any time during the  applicable  Annual  Payment
Period or Semiannual  Payment  Period,  and shall be 10 percent per annum at all
other times.

                  (b) Any dividend  payments may be made, in the sole discretion
of the Board of Directors, as follows (for purposes of this


                                        2


determination, the Designated Directors (defined below in Section 13) shall not
vote):

                           (i)      Prior to December 15, 1999:

                                    (1) on or prior to the  Original  Issue Date
and prior to December 15, 1997 and 1998, the Board of Directors  shall determine
whether  dividend  payments  payable  on the next four  Dividend  Payment  Dates
beginning  December 15 (each, an "Annual  Payment  Period") shall be paid in (i)
cash or (ii)  additional  shares of Series B  Cumulative  Convertible  Preferred
Stock valued at the  Liquidation  Preference (but not in any combination of cash
and  additional  shares of Series B  Cumulative  Convertible  Preferred  Stock);
provided, however, that the first Annual Payment Period shall commence March 15,
1997,  and run for three  Dividend  Payment Dates if the Original  Issue Date is
between December 15, 1996 and March 15, 1997;

                                    (2) in the  event  that,  during  an  Annual
Payment  Period  when the Board has  elected  to pay  dividends  on the Series B
Cumulative  Convertible  Preferred  Stock  in  cash,  the  Corporation  fails to
authorize, declare and pay in cash on a Dividend Payment Date the full amount of
the cash  dividend  due at the Cash  Dividend  Rate,  then,  on or prior to such
Dividend Payment Date, the Board shall authorize, declare and pay a supplemental
stock  dividend in shares of Series B  Cumulative  Convertible  Preferred  Stock
(valued at the  Liquidation  Preference)  equal to the  difference  between  the
dividend  that  would  have been  paid  in-kind  at the  In-Kind  Dividend  Rate
(assuming  that the Board had elected to pay dividends  for such period  in-kind
and assuming  that a Special  Default  existed) and the cash  dividend  actually
declared and paid on such  Dividend  Payment  Date and on the previous  Dividend
Payment Date during such Annual Payment Period, if any.

                           (ii)     On or after December 15, 1999:

                                    (1) On or prior to December  15, 1999 and on
or prior to each June 15 and  December  15  thereafter,  the Board of  Directors
shall  determine  whether  dividend  payments  accruing on the next two Dividend
Payment  Dates  beginning  on such  Dividend  Payment  Date (each a  "Semiannual
Payment Period") shall be paid in (i) cash or (ii) additional shares of Series B
Cumulative Convertible Preferred Stock valued at the Liquidation Preference (but
not in any  combination  of cash and  additional  shares of Series B  Cumulative
Convertible Preferred Stock);

                                    (2) in the event that,  during a  Semiannual
Payment  Period  when the Board has  elected  to pay  dividends  on the Series B
Cumulative  Convertible  Preferred  Stock  in  cash,  the  Corporation  fails to
authorize, declare and pay in cash on a Dividend Payment Date the full amount of
the cash dividend due at the Cash Dividend Rate, then, on such


                                        3


Dividend Payment Date, the Board shall authorize, declare and pay a supplemental
stock  dividend in shares of Series B  Cumulative  Convertible  Preferred  Stock
(valued at the  Liquidation  Preference)  equal to the  difference  between  the
dividend  that  would  have been  paid  in-kind  at the  In-Kind  Dividend  Rate
(assuming  that the Board had elected to pay dividends  for such period  in-kind
and assuming  that a Special  Default  existed) and the cash  dividend  actually
declared and paid on such  Dividend  Payment  Date and on the previous  Dividend
Payment Date during such Semiannual Payment Period, if any.

                           (iii) All shares of Series B  Cumulative  Convertible
Preferred  Stock  issued as a dividend  with  respect to the Series B Cumulative
Convertible Preferred Stock shall thereupon be duly authorized,  validly issued,
fully paid and nonassessable.

                  (c) In the case of shares of Series B  Cumulative  Convertible
Preferred Stock issued on the Original Issue Date, dividends shall accrue and be
cumulative  from  such  date.  In the case of  shares  of  Series  B  Cumulative
Convertible  Preferred  Stock  issued  as a  dividend  on  shares  of  Series  B
Cumulative Convertible Preferred Stock, dividends shall accrue and be cumulative
from the  dividend  payment date in respect of which such shares were (or should
have been) issued as a dividend.

                  (d) Each fractional  share of Series B Cumulative  Convertible
Preferred Stock outstanding shall be entitled to a ratably  proportionate amount
of all  dividends  accruing with respect to each  outstanding  share of Series B
Cumulative  Convertible  Preferred Stock, and all such dividends with respect to
such outstanding fractional shares shall be cumulative and shall accrue (whether
or not  declared),  and shall be payable in the same manner and at such times as
provided for above with respect to dividends on each outstanding share of Series
B Cumulative  Convertible  Preferred  Stock.  Each fractional  share of Series B
Cumulative  Convertible  Preferred Stock outstanding shall also be entitled to a
ratably  proportionate  amount of any other  distributions  made with respect to
each outstanding share of Series B Cumulative  Convertible  Preferred Stock, and
all such distributions  shall be payable in the same manner and at the same time
as distributions on each  outstanding  share of Series B Cumulative  Convertible
Preferred Stock.

                  (e) No dividends or other  distributions  shall be authorized,
declared,  paid or set apart for payment on any shares of Common  Stock or other
stock  of the  Corporation  ranking  junior  as to  dividends  to the  Series  B
Cumulative  Convertible  Preferred  Stock  (collectively,  the "Junior  Dividend
Stock") except for dividends or distributions that are not Extraordinary  Equity
Payments (defined below in Section 8(h)).


                                        4


                  (f) If at any  time any  dividend  on the  $21.25  Convertible
Exchangeable  Preferred Stock (the "$21.25  Preferred Stock") or any other stock
of the Corporation hereafter issued ranking senior as to dividends to the Series
B Cumulative Convertible Preferred Stock (collectively with the $21.25 Preferred
Stock, the "Senior  Dividend  Stock") shall be in arrears,  in whole or in part,
then (except to the extent allowed by the terms of such Senior  Dividend  Stock)
no cash dividend shall be authorized, declared, paid or set apart for payment on
the Series B Cumulative Convertible Preferred Stock unless and until all accrued
and unpaid  dividends with respect to the Senior  Dividend Stock for all payment
periods ending on or prior to the date of payment of the current dividend on the
Series B  Cumulative  Convertible  Preferred  Stock shall have been  authorized,
declared  and paid or set apart for  payment.  Dividends  payable in  additional
shares of Series B Cumulative  Convertible Preferred Stock are permitted and not
subordinated in payment to payment of dividends on the Senior Dividend Stock.

                  (g) No dividends or other  distributions  shall be authorized,
declared,  paid  or  set  apart  for  payment  on any  class  or  series  of the
Corporation's stock heretofore or hereafter issued ranking, as to dividends,  on
a parity with the Series B Cumulative  Convertible  Preferred Stock (the "Parity
Dividend  Stock") for any period unless full cumulative  dividends have been, or
contemporaneously  are, authorized,  declared and paid or set apart in trust for
such  payment on the Series B  Cumulative  Convertible  Preferred  Stock for all
dividend payment periods  terminating on or prior to the date of payment of such
full cumulative  dividends.  No full dividends (other than dividends  payable in
additional shares of Series B Cumulative  Convertible  Preferred Stock) shall be
authorized,  declared,  paid or set apart for payment on the Series B Cumulative
Convertible Preferred Stock for any period unless full cumulative dividends have
been, or contemporaneously  are, authorized,  declared and paid or set apart for
payment on the Parity Dividend Stock for all dividend periods  terminating on or
prior to the date of payment of such full  cumulative  dividends.  When  accrued
dividends are not paid in full on the Series B Cumulative  Convertible Preferred
Stock and the Parity Dividend Stock, all cash dividends authorized, declared and
paid or set apart for payment on the Series B Cumulative  Convertible  Preferred
Stock and the Parity Dividend Stock shall be authorized,  declared,  paid or set
apart for payment pro rata so that the amount of dividends authorized, declared,
paid or set apart for payment per share on the Series B  Cumulative  Convertible
Preferred  Stock and the Parity  Dividend  Stock shall in all cases bear to each
other the same ratio that accrued and unpaid dividends per share on the Series B
Cumulative  Convertible  Preferred  Stock and the Parity  Dividend Stock bear to
each other.

         4.       Liquidation Preference.


                                        5


                  (a) The  liquidation  preference  of the  Series B  Cumulative
Convertible  Preferred  Stock  shall be  $200.00  per  share  (the  "Liquidation
Preference").  Subject to the full payment of the liquidation preferences of the
$21.25  Preferred  Stock and the  shares of stock of the  Corporation  hereafter
issued  ranking  senior  as to  liquidation  rights to the  Series B  Cumulative
Convertible  Preferred Stock (the "Senior Liquidation Stock"), in the event of a
liquidation,  dissolution or winding up of the Corporation, whether voluntary or
involuntary,  the holders of shares of Series B Cumulative Convertible Preferred
Stock shall be entitled to receive out of the assets of the Corporation, whether
such assets are stated capital or surplus of any nature,  an amount equal to the
dividends accrued and unpaid on such shares on the date of final distribution to
such holders, whether or not declared, without interest, plus a sum equal to the
Liquidation  Preference,  and no more,  before any payment  shall be made or any
assets  distributed  to the holders of shares of Common Stock or any other class
or series of the  Corporation's  stock  hereafter  issued  ranking  junior as to
liquidation  rights  to the  Series B  Cumulative  Convertible  Preferred  Stock
(collectively, the "Junior Liquidation Stock").

                  (b) The assets of the Corporation  available for  distribution
after the liquidation  preferences of the Senior Liquidation Stock are fully met
shall be  distributed  ratably  among the  holders  of the  Series B  Cumulative
Convertible  Preferred Stock and any other class or series of the  Corporation's
stock  hereafter  issued ranking on a parity as to  liquidation  rights with the
Series B Cumulative  Convertible Preferred Stock in proportion to the respective
preferential  amounts to which each is entitled  (but only to the extent of such
preferential  amounts);  provided,  however,  that after  payment in full of the
Liquidation  Preferences,  the holders of the shares of the Series B  Cumulative
Convertible  Preferred Stock shall not be entitled to any further  participation
in any  distribution of assets by the  Corporation.  Neither a consolidation  or
merger of the Corporation  with or into another  corporation nor a merger of any
other corporation with or into the Corporation, nor a sale or transfer of all or
any part of the  Corporation's  assets for cash,  securities or other  property,
will be considered a liquidation, dissolution or winding up of the Corporation.

         5. Limitation on Share Repurchase.  If at any time any dividends on the
Series B  Cumulative  Convertible  Preferred  Stock  shall be in  arrears or the
Corporation  shall  have  failed  to make any  purchase  of  shares  of Series B
Cumulative Convertible Preferred Stock tendered to it pursuant to Section 7, the
Corporation  shall  not -- and  the  Corporation  shall  not  permit  any  other
corporation or legal entity directly or indirectly controlled by the Corporation
(collectively, the "subsidiaries") to -- repurchase, redeem, retire or otherwise
acquire any shares of Junior Dividend Stock,  Junior  Liquidation  Stock, or any
warrants,  rights,  calls or options  exercisable  for or  convertible  into any
shares  of  Junior  Dividend  Stock  or  Junior  Liquidation  Stock,  except  by
conversion

                                        6


into or exchange for shares of Junior Dividend Stock or Junior Liquidation Stock
and other than purchases, redemptions, retirements or acquisitions made pursuant
to and as required by the terms of any employee incentive or benefit plan of the
Corporation or any  subsidiary of the  Corporation in effect on July 24, 1996 or
as  amended  or  adopted  by the  Corporation  with  approval  of the  Executive
Committee  of the  Corporation.  Notwithstanding  the  preceding  sentence,  any
subsidiary  which is wholly owned by the  Corporation  may  repurchase,  redeem,
retire or otherwise acquire shares of its stock.

         6. Redemption at Option of the Corporation.

                  (a) So long as shares of Common Stock shall have traded on the
Primary  Exchange  (defined below) (i) for at least forty (40) of the forty-five
(45)  trading  days  (each of which  trading  days  shall  be  after  the  third
anniversary  of the Original Issue Date (the "Third  Anniversary"))  immediately
preceding the  Determination  Date (defined below),  and (ii) on each of the ten
(10)  consecutive  trading  days  immediately  prior to the  Determination  Date
(defined  below),  at a Closing Price (as hereinafter  defined) in excess of the
Hurdle Percentage (defined below) of the conversion price then in effect for the
Series B Cumulative  Convertible Preferred Stock for each such trading day, all,
but not less than all, of Series B Cumulative  Convertible  Preferred  Stock may
thereafter  be redeemed at the  election of the Board of  Directors  made on any
date (the  "Determination  Date") on or after  the  Third  Anniversary,  for the
Redemption  Price (defined below in Section 7(b)),  plus an amount in cash equal
to accrued and unpaid dividends thereon,  whether or not authorized or declared,
to  but  excluding  the  date  fixed  for   redemption.   For  purposes  of  the
determination of the Board called for in the preceding sentence,  the Designated
Directors  (defined  below in Section 13) shall not vote. The date on which such
shares shall be redeemed  shall be a date that is at least ten (10), but no more
than thirty (30),  business  days after the  Determination  Date  (during  which
period the holders of the Series B Cumulative  Convertible  Preferred Stock may,
but shall not be required to, convert such stock into Common Stock).  The Hurdle
Percentage shall be 150% from and after the Third Anniversary,  and to the fifth
anniversary of the Original Issue Date; thereafter,  the Hurdle Percentage shall
be 125%. "Primary Exchange" shall mean the American Stock Exchange or such other
principal national  securities  exchange or quotation system on which the Common
Stock of the Corporation is quoted or listed or admitted to trading.

                  (b) Not more than thirty (30) nor less than ten (10)  business
days  prior  to the  redemption  date  fixed  by the  Board  of  Directors,  the
Corporation  shall give  notice by hand or  overnight  courier to the holders of
record of shares of the Series B Cumulative  Convertible  Preferred  Stock to be
redeemed,  addressed to such  holders at their last  addresses as shown upon the
stock transfer books of the  Corporation.  Each such notice of redemption  shall
specify the date fixed for redemption; the Redemption Price (defined below in

                                        7


Section  7(b))  plus an amount in cash equal to  accrued  and  unpaid  dividends
thereon,  whether or not authorized or declared, to but excluding the date fixed
for redemption;  the place or places of payment;  that payment will be made upon
presentation  and  surrender  of the shares of Series B  Cumulative  Convertible
Preferred  Stock;  that on and after the redemption date dividends will cease to
accrue on such shares;  the then effective  conversion price pursuant to Section
8; and that the right of  holders  to  convert  shares  of  Series B  Cumulative
Convertible  Preferred  Stock  shall  terminate  at the close of business on the
business day prior to the redemption  date (unless the  Corporation  defaults in
the payment of the Redemption  Price plus an amount in cash equal to accrued and
unpaid  dividends  thereon,  whether  or  not  authorized  or  declared,  to but
excluding the date fixed for redemption).

                  (c) Any notice as herein  provided shall be deemed to be given
when delivered to the address  specified in the preceding  section.  On or after
the date  fixed for  redemption  as stated in such  notice,  each  holder of the
shares called for  redemption,  unless such holder has  exercised  such holder's
right to convert shares of Series B Cumulative  Convertible  Preferred  Stock as
provided above, shall surrender the certificate  representing such shares to the
Corporation  at the place  designated  in such  notice  and shall  thereupon  be
entitled to receive  payment of the  Redemption  Price (defined below in Section
7(b))  plus an amount in cash equal to accrued  and  unpaid  dividends  thereon,
whether or not  authorized  or  declared,  to but  excluding  the date fixed for
redemption.  If less  than all the  shares  evidenced  by any  such  surrendered
certificate are redeemed,  a new certificate  shall be issued  representing  the
unredeemed shares. Notice having been given as aforesaid,  if, on the date fixed
for redemption,  funds necessary for the redemption shall be available  therefor
and shall have been irrevocably  deposited or set aside in trust for the holders
of the  shares  of  Series  B  Cumulative  Convertible  Preferred  Stock,  then,
notwithstanding  that the  certificates  representing  any  shares so called for
redemption shall not have been surrendered, dividends with respect to the shares
so called shall cease to accrue after the date fixed for redemption, such shares
shall no longer be deemed  outstanding,  the holders  thereof  shall cease to be
stockholders of the  Corporation  and all rights  whatsoever with respect to the
shares so called for redemption  (except the right of the holders to receive the
Redemption  Price plus an amount in cash equal to accrued  and unpaid  dividends
thereon,  whether or not authorized or declared, to but excluding the date fixed
for redemption,  without interest upon surrender of their certificates therefor)
shall terminate.  If funds legally available for such purpose are not sufficient
for redemption of the shares of Series B Cumulative  Convertible Preferred Stock
to be redeemed,  then the certificates  representing such shares shall be deemed
not to be  surrendered,  such shares shall remain  outstanding and the rights of
holders of shares of Series B Cumulative  Convertible Preferred Stock thereafter
shall continue to be only those of a holder of shares of the Series B Cumulative
Convertible Preferred Stock.


                                        8


                  (d)  Except as  provided  in Section 7, the shares of Series B
Cumulative  Convertible Preferred Stock shall not be subject to the operation of
any mandatory purchase, retirement or sinking fund.

         7. Mandatory Repurchase and Repurchase at Option of the Holder.


                  (a) On the eighth  anniversary of the Original Issue Date, the
Corporation  shall  purchase  from each holder of shares of Series B  Cumulative
Convertible  Preferred  Stock  one-third of the number of shares of the Series B
Cumulative  Convertible  Preferred  Shares  held by such  holder on such  eighth
anniversary.   On  the  ninth  anniversary  of  the  Original  Issue  Date,  the
Corporation  shall  purchase  from each holder of shares of Series B  Cumulative
Convertible  Preferred  Stock  one-half  of the number of shares of the Series B
Cumulative  Convertible  Preferred  Shares  held by such  holder  on such  ninth
anniversary.   On  the  tenth  anniversary  of  the  Original  Issue  Date,  the
Corporation  shall  purchase  from each holder of shares of Series B  Cumulative
Convertible  Preferred  Stock the  number of shares of the  Series B  Cumulative
Convertible  Preferred  Shares  held by such  holder on such tenth  anniversary.
Repurchases  made  pursuant  to this  Section  7(a)  shall be  effected  on such
anniversary date (or such other day as the holder and the Corporation may agree)
and shall be for the  Redemption  Price  (defined below in Section 7(b)) plus an
amount in cash equal to the accrued and unpaid dividends thereon, whether or not
authorized  or declared,  to but excluding  the date fixed for  repurchase.  Any
shares of Series B  Cumulative  Convertible  Preferred  Stock  which  would have
accrued  but have not been paid on any shares  tendered  for  purchase  shall be
deemed to be tendered for purchase.

                  (b) (i) If one or more  Special  Defaults  shall  occur at any
time or from time to time on or after the  Original  Issue Date,  each holder of
shares of the Series B  Cumulative  Convertible  Preferred  Stock shall have the
right, at such holder's option exercisable at any time within 120 days after the
happening of each such Special  Default,  to require the Corporation to purchase
all or any part of the shares of Series B Cumulative Convertible Preferred Stock
then  held by such  holder as such  holder  may  elect at the  Redemption  Price
(defined  below) plus,  in each case, an amount in cash equal to the accrued and
unpaid  dividends  thereon,  whether  or  not  authorized  or  declared,  to but
excluding  the date  fixed for  redemption.  Any  shares of Series B  Cumulative
Convertible  Preferred  Stock which would have accrued but have not been paid on
any shares  tendered for purchase  shall be deemed to be tendered for  purchase.
The "Redemption Price" shall be the Liquidation Preference where there have been
no Special Defaults, and -- after there has been one or more Special Defaults --
shall be 130% of the greater of the  Liquidation  Preference or the market value
of the  Common  Stock  (valued  at the  average  of the  Closing  Prices  on the
preceding  twenty (20) trading days  immediately  prior to the occurrence of the
Special Default) into which the

                                        9


Series B  Cumulative  Convertible  Preferred  Stock  would  then be  convertible
assuming such shares to be immediately  convertible  (whether or not such shares
were then actually convertible);

                           (ii)  A  "Special  Default"  shall  mean  any  of the
following  events  which occur after the  Original  Issuance  Date and while any
shares of the Series B Cumulative Convertible Preferred Stock are outstanding:

                                    (1) the  disbanding or other  restructuring,
reorganization,  or reconstitution  (including  without limitation change in the
number of members) of the  Executive  Committee  of the Board  without the prior
written  approval of a majority of the members of the  Executive  Committee  who
were members prior to such change (and, for so long as the holders of the Series
B Cumulative  Convertible Preferred Stock shall have the right to designate more
than one director to the  Executive  Committee  pursuant to Section 13(b) below,
including  the members so  designated  by the holders of the Series B Cumulative
Convertible Preferred Stock);

                                    (2)  the  taking  of any  of  the  following
actions by the  Corporation  or the Board  without the approval of a majority of
the members of the Executive  Committee of the Board (whether or not such action
was  taken by the Board in view of its  fiduciary  duties  pursuant  to the last
sentence of Section 3.3(A) of the By-Laws of the Corporation,  as amended):  (A)
any borrowing or guarantee by the Corporation  exceeding $15 million, (B) except
for issuance of stock or stock options pursuant to the  Corporation's  incentive
compensation  plans or  programs,  any  issuance  of stock  (whether  common  or
preferred,  whether voting or non-voting,  whether junior, pari passu, or senior
to the Series B Cumulative  Convertible Preferred Stock) other than Common Stock
of the Corporation in an aggregate amount not exceeding five percent (5%) of the
Common Stock of the  Corporation  issued and  outstanding  on the Original Issue
Date,  (C) any strategic  alliance  (other than a  construction  joint  venture)
involving a capital commitment by the Corporation  exceeding $5 million, (D) any
asset sale by the  Corporation  or lease as lessor  exceeding $5 million  (other
than  equipment  dispositions  in  the  normal  course  of  business);  (E)  any
redemption or amendment of the Rights  (defined below) or the preferred stock of
the Corporation  issuable upon the exercise of such Rights,  or any amendment of
the Rights Agreement  (defined below),  and (F) any termination of (other than a
termination upon expiration) or amendment to the management  agreement among the
Corporation, Ronald Tutor and Tutor- Saliba Corporation; provided, however, that
for purposes of this Section  8(b)(ii)(2),  approval of the Executive  Committee
shall not be required  for any  decision by the Board of Directors to redeem the
Series B Cumulative Convertible Preferred Stock pursuant to Section 6(a);

                                    (3) any  change  by the  Corporation  in the
composition of the Executive Committee of the Board which results in


                                       10


members of such  Committee  selected by the  holders of the Series B  Cumulative
Convertible Preferred Stock pursuant to Section 13(b) below being fewer than the
number of  directors  that the  holders of the Series B  Cumulative  Convertible
Preferred Stock are then entitled to designate pursuant to that provision or the
failure of the  Corporation  to nominate for director the persons  designated by
the holders of the Series B Cumulative Convertible Preferred Stock in accordance
with Section 13(a) below; or

                                    (4)  solely  for  purposes  of the  right to
elect additional  directors pursuant to Section 9(b) and not for purposes of any
other Section,  the failure of the  Corporation to authorize,  declare,  and pay
dividends payable in Series B Cumulative Convertible Preferred Stock when due in
accordance with Section 3.

                  (c) The date fixed for each such  repurchase  shall be (x) the
anniversary of the Original Issue Date  immediately  succeeding the notice given
pursuant to Section 7(a),  or (y) the 121st day following the  occurrence of the
Special Default giving rise to a repurchase  pursuant to Section 7(b). The place
of  payment  shall be at an  office or agency  in  Boston,  Massachusetts  fixed
therefor by the Corporation or, if not fixed, at the principal  executive office
of the Corporation.

                  (d) The Corporation shall, within 20 days of the occurrence of
a Special  Default,  give a written  notice  thereof by  registered or certified
mail,  postage prepaid,  return receipt  requested,  to the holders of record of
shares of the Series B Cumulative Convertible Preferred Stock, addressed to such
holders at their last  addresses as shown upon the stock  transfer  books of the
Corporation.  Each such  notice  shall  specify the  Special  Default  which has
occurred and the date of such  occurrence,  the place or places of payment,  the
then  effective  conversion  price  pursuant  to Section  8, the then  effective
repurchase  price  and the  date  the  right  of such  holder  to  require  such
repurchase shall  terminate.  Any notice that is mailed as herein provided shall
be conclusively  presumed to have been duly given,  whether or not the holder of
shares of Series B Cumulative  Convertible Preferred Stock receives such notice;
and failure to give such notice by mail,  or any defect in such  notice,  to the
holders of any shares shall not affect the validity of the  proceedings  for the
repurchase  of any other  shares of Series B  Cumulative  Convertible  Preferred
Stock.

                  (e) (i) On the date fixed for any such repurchase, each holder
of shares of Series B Cumulative  Convertible Preferred Stock who elects to have
shares of Series B Cumulative  Convertible  Preferred Stock held by it purchased
shall surrender the certificate  representing  such shares to the Corporation at
the place  designated  in such  notice  together  with an  election to have such
purchase  made and shall  thereupon  be  entitled  to receive  payment  therefor
provided in this Section 7. If less than all the shares represented by


                                       11


any such  surrendered  certificate are repurchased,  a new certificate  shall be
issued representing the unpurchased shares. Dividends with respect to the shares
of Series B Cumulative  Convertible  Preferred Stock so purchased shall cease to
accrue  after  the date so  purchased,  such  shares  shall no  longer be deemed
outstanding  after  such  date  and  the  holders  thereof  shall  cease  to  be
stockholders of the  Corporation  and all rights  whatsoever with respect to the
shares so purchased shall terminate.

                           (ii) If the funds legally available for such purchase
are not sufficient to purchase all the shares of Series B Cumulative Convertible
Preferred Stock tendered to the Corporation for purchase,  the Corporation shall
purchase  the  greatest  number  of whole  shares  for which  such  funds are so
available on a pro rata basis among all tendering  holders based on the ratio of
the number of shares  tendered  by each of them to the  aggregate  amount of all
shares so tendered,  and the certificates  representing  the unpurchased  shares
shall be deemed not to be surrendered for repurchase,  such  unpurchased  shares
shall  remain  outstanding  and the rights of the  holders of shares of Series B
Cumulative  Convertible Preferred Stock thereafter shall continue to be those of
a holder of shares  of the  Series B  Cumulative  Convertible  Preferred  Stock;
provided,  however,  the Corporation  shall thereafter be required to repurchase
all such  remaining  shares at the first date it has  sufficient  funds  legally
available  for such  purpose  at the  price it would  have paid at the date such
shares were actually tendered and the Corporation shall give notice as aforesaid
to each holder whose shares were not repurchased for such reason and such holder
shall thereafter have the right to elect to have such shares  repurchased,  such
election to be made within 30 days of receipt of such  notice.  For  purposes of
this  Section,  the  Corporation  shall be deemed not to have  sufficient  funds
legally  available  for any such  purchase if the Board of Directors  reasonably
determines  that  immediately  after such  repurchase the  Corporation  would be
insolvent.

                           (iii) For so long as there remain  shares of Series B
Cumulative Convertible Preferred Stock that have been surrendered for repurchase
in  accordance  with this  Section 7 that  have not been so  repurchased  by the
Corporation:  (1) the  number  of  members  of the Board of  Directors  shall be
increased by such number as is necessary to allow the election of the  directors
specified  in clause (2) of this  Section,  and (2) the  holders of the Series B
Cumulative Convertible Preferred Stock, voting separately as a class, shall have
the right to elect an  additional  number of directors to the Board of Directors
such that the Designated Directors (defined below in Section 13) who are serving
on the Board of Directors,  plus the directors elected by such holders voting as
a class under this  clause,  constitute  a majority  of Board.  The right of the
holders of the Series B Cumulative  Convertible Preferred Stock to vote for such
additional  directors  shall  terminate  when shares of the Series B  Cumulative
Convertible  Preferred Stock properly  tendered for repurchase  pursuant to this
Section 7 have been repurchased. The term of


                                       12



office  of all  directors  so  elected  shall  terminate  immediately  upon  the
termination  of the right of the holders of the Series B Cumulative  Convertible
Preferred  Stock  to vote for  such  additional  directors,  and the  number  of
directors of the Board of Directors shall immediately thereafter be reduced.

                           (iv) The foregoing right of the holders of the Series
B  Cumulative  Convertible  Preferred  Stock  with  respect to the  election  of
additional  directors may be exercised at each annual meeting of stockholders or
at any special  meeting of stockholders  held for such purpose.  If the right to
elect  additional  directors  shall have  accrued to the holders of the Series B
Cumulative  Convertible Preferred Stock more than thirty (30) days preceding the
date established for the next annual meeting of  stockholders,  the President of
the  Corporation  shall,  within  five  (5)  days  after  the  delivery  to  the
Corporation at its principal  office of a written  request for a special meeting
signed by the holders of at least 10% of all outstanding  shares of the Series B
Cumulative Convertible Preferred Stock, call a special meeting of the holders of
the Series B Cumulative  Convertible  Preferred  Stock to be held as promptly as
practicable  after the delivery of such request for the purpose of electing such
additional directors.

                           (v)  The   holders   of  the   Series  B   Cumulative
Convertible  Preferred  Stock  voting as a class  shall have the right to remove
with or without cause at any time and replace any  directors  such holders shall
have  elected  pursuant to this Section 7 and the holders of each other class of
stock of the Corporation shall not have the right to remove any such directors.

         8.       Conversion.

                  (a) Right of  Conversion.  Each  share of Series B  Cumulative
Convertible  Preferred Stock, whether issued originally or in-kind as a dividend
payment,  shall be convertible at the option of the holder thereof,  at any time
(provided, however, that where the Corporation has elected to redeem such stock,
the option of the holder  described in this  section must be exercised  prior to
the close of business on the business day prior to the date fixed for redemption
of such share as herein provided),  into fully paid and nonassessable  shares of
Common Stock and such other securities and property as hereinafter  provided, at
the rate of that number of shares of Common  Stock for each full share of Series
B  Cumulative  Convertible  Preferred  Stock  that is equal  to the  Liquidation
Preference  plus an amount in cash equal to the  accrued  and  unpaid  dividends
thereon, whether or not authorized or declared,  divided by the conversion price
applicable  per share of Common Stock.  For purposes of this Section  8(a),  the
"conversion price" applicable per share of Common Stock shall initially be equal
to Nine Dollars and Sixty-Eight and Two-Hundred Nineteen  One-Thousandths  Cents
($9.68219),   and  shall  be   adjusted   from  time  to  time  to  the  nearest
one-thousandth  of a cent after the Original  Issue Date in accordance  with the
provisions of this Section 8.


                                       13



                  (b)      Conversion Procedures.

                           (i) Any  holder  of  shares  of  Series B  Cumulative
Convertible  Preferred  Stock  desiring to convert such shares into Common Stock
shall  surrender the  certificate or  certificates  representing  such shares of
Series B Cumulative  Convertible  Preferred  Stock at the office of the transfer
agent for the Series B Cumulative Convertible Preferred Stock, which certificate
or certificates,  if the Corporation shall so require, shall be duly endorsed to
the Corporation or in blank, or accompanied by proper instruments of transfer to
the  Corporation or in blank,  accompanied by irrevocable  written notice to the
Corporation  that the  holder  elects  so to  convert  such  shares  of Series B
Cumulative  Convertible  Preferred  Stock and specifying the name or names (with
address or addresses) in which a certificate or certificates  evidencing  shares
of Common Stock are to be issued.

                           (ii) Subject to Section  8(k) hereof,  no payments or
adjustments in respect of dividends on shares of Series B Cumulative Convertible
Preferred Stock  surrendered for conversion or on account of any dividend on the
Common Stock issued upon  conversion  shall be made upon the  conversion  of any
shares of Series B Cumulative Convertible Preferred Stock.

                           (iii) The  Corporation  shall, as soon as practicable
after such deposit of  certificates  representing  shares of Series B Cumulative
Convertible  Preferred  Stock  accompanied  by the written notice and compliance
with any  other  conditions  herein  contained,  deliver  at such  office of the
transfer  agent  to the  person  for  whose  account  such  shares  of  Series B
Cumulative  Convertible Preferred Stock were so surrendered or to the nominee or
nominees of such person  certificates  representing the number of full shares of
Common Stock to which such person shall be entitled as aforesaid,  together with
a cash  adjustment  in respect  of any  fraction  of a share of Common  Stock as
hereinafter  provided.  Subject to the following  provisions of this  paragraph,
such  conversion  shall  be  deemed  to have  been  made as of the  date of such
surrender of the shares of Series B Cumulative Convertible Preferred Stock to be
converted,  and the  person or persons  entitled  to  receive  the Common  Stock
deliverable  upon conversion of such Series B Cumulative  Convertible  Preferred
Stock shall be treated for all purposes as the record  holder or holders of such
Common Stock on such date.

                  (c) Adjustment of Conversion  Price.  The conversion  price at
which a share of Series B Cumulative  Convertible Preferred Stock is convertible
into Common Stock shall be subject to adjustment from time to time as follows:

                           (i) (1) In case the  Corporation  shall pay or make a
dividend or other distribution on its Common Stock exclusively in Common


                                       14


Stock or shall pay or make a dividend or other  distribution  on any other class
of stock of the Corporation which dividend or distribution includes Common Stock
or shall  exchange  outstanding  Rights (as defined in Section  8(j) hereof) for
shares of Common  Stock,  the  conversion  price in  effect  at the  opening  of
business  on  the  day  following  the  date  fixed  for  the  determination  of
stockholders  entitled  to receive  such  dividend or other  distribution  or to
exchange such Rights shall be reduced by multiplying  such conversion price by a
fraction of which the  numerator  shall be the number of shares of Common  Stock
outstanding  at the close of business  on the date fixed for such  determination
and the  denominator  shall be the sum of such  number of  shares  and the total
number of shares  constituting such dividend or other  distribution or exchange,
such reduction to become effective  immediately after the opening of business on
the day following the date fixed for such determination.

                                    (2) In case the  Corporation  shall issue or
otherwise  sell or  distribute  shares of Common Stock for a  consideration  per
share in cash or property  less than the most recent  Closing Price prior to the
time of such issuance (and, if shares are issued,  sold, or distributed pursuant
to the exercise or conversion of options,  warrants,  convertible securities, or
other  rights,  the exercise or  conversion  price  thereof  when such  options,
warrants, convertible securities, or rights were granted or issued was less than
the Closing Price (defined below in Section 8(h) at the time of issuance of such
options,  warrants,  convertible  securities,  or other rights),  the conversion
price then in effect shall be reduced by multiplying  such conversion price by a
fraction of which the  numerator  shall be the number of shares of Common  Stock
outstanding  immediately  prior to such issuance,  sale or distribution plus the
number of shares of Common Stock which the aggregate  consideration  received by
the Corporation for such issuance, sale or distribution (such consideration,  if
other than cash, as determined  by the Board of Directors,  whose  determination
shall be conclusive  and  described in a vote of the Board of  Directors)  would
purchase at the current market price per share and the denominator  shall be the
number of shares of Common Stock outstanding  immediately after giving effecting
to such issuance, sale or distribution.

                           (ii)  In case  the  Corporation  shall  pay or make a
dividend or other distribution on its Common Stock consisting exclusively of, or
shall otherwise issue to all or  substantially  all holders of its Common Stock,
rights or warrants  entitling  the holders  thereof to subscribe for or purchase
shares of Common  Stock at a price per share less than the then  current  market
price per share  (determined as provided in  subparagraph  (vii) of this Section
8(c))  of  the  Common  Stock  on  the  date  fixed  for  the  determination  of
stockholders  entitled to receive such rights or warrants,  the conversion price
in effect at the  opening of business  on the day  following  the date fixed for
such  determination  shall be reduced by multiplying  such conversion price by a
fraction of which the  numerator  shall be the number of shares of Common  Stock
outstanding at the close of business on the date fixed for such


                                       15


determination  plus the number of shares of Common Stock which the  aggregate of
the offering  price of the total number of shares of Common Stock so offered for
subscription  or purchase  would  purchase at such current  market price and the
denominator  shall be the number of shares of Common  Stock  outstanding  at the
close of  business on the date fixed for such  determination  plus the number of
shares of Common Stock so offered for  subscription or purchase,  such reduction
to  become  effective  immediately  after the  opening  of  business  on the day
following the date fixed for such determination.  In case any rights or warrants
referred to in this  subparagraph  (ii) in respect of which an adjustment  shall
have  been  made  shall  expire  unexercised,  the  conversion  price  shall  be
readjusted  at the time of such  expiration to the  conversion  price that would
have  been  in  effect  if no  adjustment  had  been  made  on  account  of  the
distribution or issuance of such expired rights or warrants. For the purposes of
this Section 8(c)(ii), if both a Distribution Date and a Section 11(a)(ii) Event
(as  such  terms  are  defined  in  the  Rights  Agreement  by and  between  the
Corporation  and the First  National  Bank at Boston,  dated as of September 23,
1988, as amended (the "Rights  Agreement")) shall have occurred,  then the later
to occur of such events shall be deemed to  constitute  an issuance of rights to
purchase shares of Common Stock.

                           (iii) In case  outstanding  shares  of  Common  Stock
shall be  subdivided  into a greater  number of  shares  of  Common  Stock,  the
conversion  price in effect at the opening of business on the day  following the
day upon which  such  subdivision  becomes  effective  shall be  proportionately
reduced,  and conversely,  in case outstanding shares of Common Stock shall each
be combined  into a smaller  number of shares of Common  Stock,  the  conversion
price in effect at the  opening of business  on the day  following  the day upon
which such combination  becomes  effective shall be  proportionately  increased,
such reduction or increase,  as the case may be, to become effective immediately
after the  opening  of  business  on the day  following  the day upon which such
subdivision or combination becomes effective.

                           (iv) (1) In case the  Corporation  shall, by dividend
or otherwise,  make a Section  8(c)(iv)  Distribution  (defined below in Section
8(h)) to all or  substantially  all holders of its Common Stock,  the conversion
price  shall be  reduced so that the same shall  equal the price  determined  by
multiplying the conversion  price in effect  immediately  following the close of
business on the Determination Date (as defined in Section 8(h)) by a fraction of
which the numerator  shall be the current market price per share  (determined as
provided in subparagraph  (vii) of this Section 8(c)) of the Common Stock on the
Determination  Date less the fair market  value (as  determined  by the Board of
Directors, whose determination shall be conclusive and described in a resolution
of the Board of Directors), on the date of such effectiveness, of the portion of
the Section  8(c)(iv)  Distribution  so  distributed  applicable to one share of
Common Stock and the denominator shall be such current market price per share of
the Common Stock, such reduction to become effective


                                       16


immediately  prior  to  the  opening  of  business  on  the  day  following  the
Determination  Date.  If the Board of Directors so  determines  as aforesaid the
fair market value of any distribution for purposes of this  subparagraph (iv) by
reference  to the  actual  or  when-issued  trading  market  for any  securities
comprising  such  distribution,  it must in doing so consider the prices in such
market over the same period used in computing the current market price per share
of Common Stock pursuant to subparagraph (vii) of this Section 8(c).

                                    (2)  Notwithstanding  the foregoing,  if the
Corporation  elects to reserve,  for distribution to the holders of the Series B
Cumulative  Convertible  Preferred  Stock upon the  conversion  of the shares of
Series  B  Cumulative   Convertible   Preferred  Stock,  the  evidences  of  the
Corporation's  indebtedness,  shares of any class of stock, or assets that would
have been  distributed  to the  holders of the Series B  Cumulative  Convertible
Preferred  Stock if they had converted  their shares into shares of Common Stock
so that any such holder  converting  shares of Series B  Cumulative  Convertible
Preferred Stock will receive upon such conversion,  in addition to the shares of
the Common Stock to which such holder is  entitled,  the amount and kind of such
evidences of the  Corporation's  indebtedness,  shares of any class of stock, or
assets  which such holder  would have  received if such holder had,  immediately
prior to the Determination  Date for such distribution of securities,  converted
its shares of Series B Cumulative Convertible Preferred Stock into Common Stock,
the fair market value of the securities shall, for purposes of this subparagraph
(iv), be deemed to be zero.

                           (v) Subject to the last sentence of this subparagraph
(v),  in case the  Corporation  shall,  by dividend  or  otherwise,  at any time
distribute  to  all  holders  of its  Common  Stock  cash  (excluding  any  cash
representing  an amount per share of  capital  stock of the  Corporation  to the
extent such cash does not  constitute  an  Extraordinary  Equity  Payment),  the
conversion  price  shall be  reduced  so that the same  shall  equal  the  price
determined by multiplying the conversion  price in effect  immediately  prior to
the  effectiveness  of the  conversion  price  reduction  contemplated  by  this
subparagraph  (v) by a  fraction  of which the  numerator  shall be the  current
market price per share  (determined  as provided in  subparagraph  (vii) of this
Section 8(c)) of the Common Stock on the  Determination  Date less the amount of
cash so distributed  and not excluded as above provided  applicable to one share
of Common Stock and the denominator shall be such current market price per share
of the Common Stock, such reduction to become effective immediately prior to the
opening of business on the day following the Determination Date. Notwithstanding
the foregoing,  if the Corporation  elects to reserve the cash to be distributed
for distribution to the holders of the Series B Cumulative Convertible Preferred
Stock  upon the  conversion  of the  shares of Series B  Cumulative  Convertible
Preferred Stock so that any such holder converting shares of Series B Cumulative
Convertible  Preferred Stock will receive upon such  conversion,  in addition to
the shares of the Common Stock


                                       17



to which such holder is  entitled,  the amount of cash which such  holder  would
have received if such holder had,  immediately prior to the  Determination  Date
for such  distribution  of cash,  converted  its  shares of Series B  Cumulative
Convertible  Preferred Stock into Common Stock,  then the conversion price shall
not be so reduced.

                           (vi) In case a tender or  exchange  offer made by the
Corporation or any subsidiary of the  Corporation  for all or any portion of the
Corporation's  Common Stock shall expire and such tender or exchange offer shall
involve the payment by the Corporation or such subsidiary of  consideration  per
share of Common Stock having a fair market value (as  determined by the Board of
Directors, whose determination shall be conclusive and described in a resolution
of the Board of Directors) at the last time (the  "Expiration  Time") tenders or
exchanges  may be made  pursuant to such  tender or exchange  offer (as it shall
have been amended) that exceeds the current  market price per share  (determined
as provided in  subparagraph  (vii) of this Section 8(c)) of the Common Stock on
the Trading Day next succeeding the Expiration  Time, the conversion price shall
be reduced so that the same shall equal the price  determined by multiplying the
conversion  price  in  effect  immediately  prior  to the  Expiration  Time by a
fraction of which the  numerator  shall be the number of shares of Common  Stock
outstanding  (including any tendered or exchanged shares) on the Expiration Time
multiplied  by the current  market  price per share  (determined  as provided in
subparagraph  (vii) of this Section 8(c)) of the Common Stock on the Trading Day
next succeeding the Expiration Time and the denominator  shall be the sum of (x)
the fair market value  (determined as aforesaid) of the aggregate  consideration
payable to stockholders  based on the acceptance (up to any maximum specified in
the terms of the tender or  exchange  offer) of all shares  validly  tendered or
exchanged  and not  withdrawn as of the  Expiration  Time (the shares  deemed so
accepted,  up to any such maximum,  being referred to as the "Purchased Shares")
and (y) the product of the number of shares of Common  Stock  outstanding  (less
any Purchased  Shares) on the  Expiration  Time and the current market price per
share (determined as provided in subparagraph (vii) of this Section 8(c)) of the
Common  Stock on the Trading  Day next  succeeding  the  Expiration  Time,  such
reduction to become  effective  immediately  prior to the opening of business on
the day following the Expiration Time.

                           (vii) For  purposes  of any  computation  under  this
section, the current market price per share of Common Stock on any date shall be
deemed to be the  volume-weighted  average trading price of the Common Stock for
the five-day  period before the earlier of the day in question and the "ex" date
with  respect  to any  issuance  or  distribution  requiring  such  computation;
provided,  however,  that for  purposes  of clause  (3) of this  paragraph,  the
current market price per share shall be deemed to be the volume-weighted average
trading  price of the Common Stock for the five-day  period after the "ex date."
For purposes of this subparagraph (vii), the term


                                       18


"ex" date, (1) when used with respect to any issuance or distribution, means the
first date on which the Common Stock trades regular way on the relevant exchange
or in the relevant market from which the Closing Price was obtained  without the
right to receive such  issuance or  distribution,  (2) when used with respect to
any  subdivision or combination of shares of Common Stock,  means the first date
on which the Common Stock trades  regular way on such exchange or in such market
after the time at which such subdivision or combination  becomes effective,  and
(3) when used with respect to any tender or exchange offer, means the first date
on which the Common Stock trades  regular way on such exchange or in such market
after the Expiration Time of such offer.

                           (viii) The  Corporation  may make such  reductions in
the conversion price, in addition to those required by subparagraphs  (i), (ii),
(iii),  (iv), (v) and (vi) of this Section 8(c), as it considers to be advisable
to avoid or  diminish  any income  tax to  holders of Common  Stock or rights to
purchase  Common Stock  resulting from any dividend or distribution of stock (or
rights to  acquire  stock)  or from any event  treated  as such for  income  tax
purposes.

                           (ix) No adjustment in the  conversion  price shall be
required  unless  such  adjustment  would  require an increase or decrease of at
least 1% in the conversion price; provided,  however, that any adjustments which
by reason of this subparagraph (ix) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment.

                           (x)  Notwithstanding  any  other  provision  of  this
Section 8 and without  implication that the contrary would otherwise be true, no
issuance,  dividend or distribution requiring adjustment of the conversion price
pursuant to Section  8(c) hereof  shall be deemed to have  occurred in the event
that, upon,  following or in connection with the redemption or expiration of the
Rights or the termination of the Rights Agreement or otherwise,  the Corporation
enters  into a new  agreement  that is  comparable  in purpose and effect to the
Rights Agreement (as determined by the Board of Directors,  whose  determination
shall be conclusive)  and  distributes  rights to purchase  Preferred  Stock (or
other similar stock  purchase  rights under such  agreement that are attached to
the Common Stock) to the holders of Common Stock.

                           (xi)  Whenever  the  conversion  price is adjusted as
herein provided:

                                    (1)  the   Corporation   shall  compute  the
adjusted  conversion  price  and  shall  prepare  a  certificate  signed  by the
Treasurer of the  Corporation  setting forth the adjusted  conversion  price and
showing in reasonable  detail the acts upon which such adjustment is based,  and
such certificate shall forthwith be filed with the transfer agent for the Series
B Cumulative Convertible Preferred Stock; and


                                       19


                                    (2) a notice  stating the  conversion  price
has been  adjusted  and  setting  forth  the  adjusted  conversion  price  shall
forthwith be required,  and as soon as  practicable  after it is required,  such
notice  shall be mailed by the  Corporation  to all record  holders of shares of
Series B Cumulative  Convertible Preferred Stock at their last addresses as they
shall appear upon the stock transfer books of the Corporation.

                  (d) No  Fractional  Shares.  No  fractional  shares  or  scrip
representing  fractional  shares of Common Stock shall be issued upon conversion
of Series B Cumulative Convertible Preferred Stock. If more than one certificate
representing shares of Series B Cumulative  Convertible Preferred Stock shall be
surrendered  for  conversion at one time by the same holder,  the number of full
shares  issuable upon  conversion  thereof shall be computed on the basis of the
aggregate number of shares of Series B Cumulative Convertible Preferred Stock so
surrendered.  Instead  of any  fractional  share  of  Common  Stock  that  would
otherwise  be  issuable  upon  conversion  of any shares of Series B  Cumulative
Convertible  Preferred  Stock,  the  Corporation  shall pay a cash adjustment in
respect of such  fractional  interest in an amount equal to the same fraction of
the  market  price  per share of Common  Stock  (as  determined  by the Board of
Directors or in any manner prescribed by the Board of Directors,  which, so long
as the Common  Stock is listed on the Primary  Exchange,  shall be the  reported
last sale price regular way on the Primary Exchange) at the close of business on
the day of conversion.

                  (e)  Reclassification,   Consolidation,  Merger,  or  Sale  of
Assets. If any capital  reorganization or  reclassification of the capital stock
of the  Corporation,  or consolidation or merger of the Corporation with another
corporation,  or the sale of all or  substantially  all of its assets to another
corporation  shall be effected in such a way that  holders of Common Stock shall
be entitled to receive stock, securities, cash or other property with respect to
or in exchange for Common Stock,  then,  as a condition of such  reorganization,
reclassification,  consolidation,  merger or sale, lawful and adequate provision
shall  be made  whereby  the  holders  of the  Series B  Cumulative  Convertible
Preferred  Stock shall have the right to acquire and receive upon  conversion of
the Series B Cumulative  Convertible  Preferred Stock, which right shall be pari
passu  with the rights of  holders  of Parity  Dividend  Stock and senior to the
rights of the holders of Junior Dividend Stock and Junior Liquidation Stock (but
after and subject to the rights of holders of Senior  Dividend  Stock and Senior
Liquidation  Stock,  if any),  such shares of stock,  securities,  cash or other
property issuable or payable (as part of the  reorganization,  reclassification,
consolidation, merger or sale) with respect to or in exchange for such number of
outstanding  shares of Common Stock as would have been received upon  conversion
of the Series B Cumulative  Convertible  Preferred Stock at the conversion price
then in effect,

                                       20


whether or not such stock is then  convertible.  The Corporation will not effect
any such consolidation, merger or sale, unless prior to the consummation thereof
the successor  corporation (if other than the  Corporation)  resulting from such
consolidation  or merger or the corporation  purchasing such assets shall assume
by written  instrument in reasonable  and customary  form mailed or delivered to
the holders of the Series B Cumulative  Convertible  Preferred Stock at the last
address  of each such  holder  appearing  on the books of the  Corporation,  the
obligation  to deliver to each such holder such shares of stock,  securities  or
assets as, in  accordance  with the  foregoing  provisions,  such  holder may be
entitled to purchase.

                  (f) Reservation of Shares; Transfer Taxes; Etc.

                           (i) The  Corporation  shall at all times  reserve and
keep available, out of its authorized and unissued stock, solely for the purpose
of effecting  the  conversion of the Series B Cumulative  Convertible  Preferred
Stock,  such  number of  shares of its  Common  Stock or  Common  Stock  free of
preemptive  rights  as shall  from  time to time be  sufficient  to  effect  the
conversion of all shares of Series B Cumulative Convertible Preferred Stock from
time to time outstanding. The Corporation shall from time to time, in accordance
with the laws of the State of  Massachusetts,  increase the number of authorized
shares of Common  Stock if at any time the  number of shares of  authorized  and
unissued  Common Stock shall not be sufficient  to permit the  conversion of all
the then outstanding shares of Series B Cumulative Convertible Preferred Stock.

                           (ii) If any  shares of Common  Stock  required  to be
reserved  for  purposes of  conversion  of the Series B  Cumulative  Convertible
Preferred  Stock  hereunder  require   registration  with  or  approval  of  any
governmental  authority under any Federal or State law before such shares may be
issued upon conversion,  the Corporation will in good faith and as expeditiously
as possible endeavor to cause such shares to be duly registered or approved,  as
the case may be. If the Common Stock is listed on the American Stock Exchange or
any other  national  securities  exchange or  national  quotation  service,  the
Corporation will list and keep listed on such exchange,  upon official notice of
issuance,  all shares of Common Stock issuable upon  conversion of the shares of
Series B Cumulative Convertible Preferred Stock.

                           (iii) The Corporation  shall pay any and all issue or
other taxes that may be payable in respect of any issue or delivery of shares of
Common  Stock on  conversion  of the Series B Cumulative  Convertible  Preferred
Stock. The Corporation shall not, however,  be required to pay any tax which may
be payable  in respect of any  transfer  involved  in the issue or  delivery  of
Common Stock (or other  securities or assets) in a name other than that in which
the shares of Series B Cumulative  Convertible Preferred Stock so converted were
registered, and no such issue or delivery shall be made unless


                                       21


and until the  person  requesting  such  issue has paid to the  Corporation  the
amount of such tax or has  established,  to the satisfaction of the Corporation,
that such tax has been paid.

                  (g) Prior Notice of Certain Events. In case:

                           (i) the  Corporation  shall  declare or  authorize  a
redemption or  repurchase  of in excess of five percent of the then  outstanding
shares of Common Stock; or

                           (ii) the Corporation  shall authorize the granting to
all holders of Common Stock of rights or warrants to  subscribe  for or purchase
any shares of stock of any class or of any other rights or warrants  (other than
pursuant to the Rights  Agreement or,  following the redemption or expiration of
the Rights or the  termination  of the  Rights  Agreement,  any new  shareholder
rights  agreement  that is  comparable  in  purpose  and  effect  to the  Rights
Agreement); or

                           (iii) of any  reclassification of Common Stock (other
than a subdivision or combination of the  outstanding  Common Stock, or a change
in par  value,  or from par value to no par  value,  or from no par value to par
value),  or of any  consolidation  or merger to which the Corporation is a party
and for which approval of any stockholders of the Corporation shall be required,
or of the sale or  transfer  of all or  substantially  all of the  assets of the
Corporation  or of any  compulsory  share  exchange  whereby the Common Stock is
converted into other securities, cash or other property; or

                           (iv) of the  voluntary  or  involuntary  dissolution,
liquidation or winding up of the Corporation;

then the  Corporation  shall cause to be filed with the  transfer  agent for the
Series B Cumulative Convertible Preferred Stock, and shall cause to be mailed to
the holders of record of the Series B Cumulative Convertible Preferred Stock, at
their last  addresses as they shall appear upon the stock  transfer books of the
Corporation,  at  least  fifteen  days  prior  to  the  applicable  record  date
hereinafter specified, a notice stating, as the case may be, (x) the record date
(if any) for the purpose of such dividend, distribution,  redemption, repurchase
or granting of rights or warrants  or, if no record date is to be set,  the date
as of which the  holders  of  Common  Stock of  record  to be  entitled  to such
dividend,  distribution,  redemption, rights or warrants are to be determined or
(y) the  date on  which  such  reclassification,  consolidation,  merger,  sale,
transfer, share exchange, dissolution,  liquidation or winding up is expected to
become effective,  and the date, if any, as of which it is expected that holders
of shares of Common Stock of record  shall be entitled to exchange  their shares
of  Common  Stock  for  securities  or  other  property  deliverable  upon  such
reclassification, consolidation, merger, sale, transfer, share exchange,


                                       22


dissolution,  liquidation  or winding up (but no failure to mail such  notice or
any defect  therein or in the mailing  thereof  shall affect the validity of the
corporate action required to be specified in such notice).

                  (h)  Definitions.  The  following  definitions  shall apply to
terms used in this Section 8:

                           (i) "Closing Price" on any day shall mean the closing
sale price  regular way on such day or, in case no such sale takes place on such
day,  the average of the reported  closing bid and asked prices  regular way, in
each case on the  Primary  Exchange,  or, if not quoted or listed or admitted to
trading on any national  securities exchange or quotation system, the average of
the closing  bid and asked  prices of the Common  Stock on the  over-the-counter
market on the day in  question  as reported  by the  National  Quotation  Bureau
Incorporated,  or a similarly generally accepted reporting service, or if not so
available in such manner,  as furnished by any American  Stock  Exchange  member
firm selected from time to time by the Board of Directors of the Corporation for
that purpose.

                           (ii) "Determination Date" shall mean, with respect to
any dividend, distribution or other transaction or event in which the holders of
Common Stock have the right to receive any cash, securities or other property or
assets or in which the Common Stock (or other applicable  security) is exchanged
for or converted into any combination of cash, securities or other property, the
date fixed for  determination  of  stockholders  entitled to receive  such cash,
securities or other property or assets  (whether such date is fixed by the Board
of Directors or by statute, contract or otherwise).

                           (iii) "Extraordinary Equity Payment" shall mean:

                                    (1) the  declaration  or payment on or after
the Original Issue Date by the  Corporation,  or any of its  subsidiaries of any
dividend or distribution on any class or series of its stock other than:

                                            (A)  any  dividend  or  distribution
from one  subsidiary  of the  Corporation  to a  wholly-owned  subsidiary of the
Corporation or from a subsidiary of the Corporation to the Corporation; provided
that  all of  such  dividend  paid  or  distribution  made,  net  of  applicable
withholding taxes, is received by the Corporation, or such recipient subsidiary;

                                            (B) any regularly scheduled (whether
or not overdue)  periodic cash dividend on the $21.25 Preferred Stock and Series
B Cumulative Convertible Preferred Stock in accordance with the terms thereof as
in effect on the Original Issue Date;


                                       23



                                            (C) any cash dividends on the Common
Stock or other  capital  stock  after  September  1, 2001 that do not  exceed in
aggregate more than twenty-five percent (25%) of the Corporation's  consolidated
net income  available for distribution to common  shareholders  (after preferred
dividends);  provided, however, that the Corporation shall have elected, for the
preceding four fiscal quarters, to pay cash dividends on the Series B Cumulative
Convertible  Preferred  Stock and shall have paid in full such dividends in cash
when due;

                                    (2)    any     repurchases,     redemptions,
retirements or other  acquisitions  directly or indirectly by the Corporation or
any of its  subsidiaries on or after the Original Issue Date of any stock of the
Corporation or any of its  subsidiaries  (other than a wholly-owned  subsidiary)
(other than  redemptions or  repurchases of the Series B Cumulative  Convertible
Preferred Stock in accordance with Sections 6 and 7).

                           (iv)  "Fundamental  Change" shall mean the occurrence
of any  transaction or event in connection with a plan or agreement to which, in
either case, the  Corporation is a party pursuant to which all or  substantially
all of the  shares of Common  Stock  shall be  exchanged  for,  converted  into,
acquired  for or  constitute  solely  the  right to  receive  cash,  securities,
property or other assets  (whether by means of an exchange  offer,  liquidation,
tender   offer,   consolidation,    merger,    combination,    reclassification,
recapitalization  or  otherwise);  provided,  however,  in  the  case  of a plan
involving more than one such transaction or event, for purposes of adjustment of
the conversion price,  such Fundamental  Change shall be deemed to have occurred
when substantially all of the shares of Common Stock of the Corporation shall be
exchanged for,  converted into or acquired for or constitute solely the right to
receive cash, securities,  property or other assets, but the adjustment shall be
based upon the consideration  which the holders of Common Stock received in such
transaction  or event as a result of which more than 50% of the shares of Common
Stock of the  Corporation  shall have been  exchanged  for,  converted  into, or
acquired  for or  constitute  solely  the  right to  receive  cash,  securities,
property or other assets; provided, further, that such term does not include (i)
any  such  transaction  or  event in which  the  Corporation  and/or  any of its
subsidiaries  are the  issuers of all the cash,  securities,  property  or other
assets exchanged,  acquired or otherwise issued in such transaction or event, or
(ii) any such  transaction or event in which the holders of Common Stock receive
securities of an issuer other than the  Corporation  if,  immediately  following
such transaction or event, such holders hold a majority of the securities having
the power to vote  normally in the  election of  directors  of such other issuer
outstanding immediately following such transaction or other event.

                           (v)  "Section  8(c)(iv)   Distribution"   shall  mean
evidences of the  Corporation's  indebtedness,  shares of any class of stock, or
assets,  including securities,  but excluding any rights or warrants referred to
in

                                       24



subparagraph  (ii) of Section 8(c),  excluding any dividend or distribution paid
in cash, and excluding any dividend or distribution  referred to in subparagraph
(i) of Section 8(c).

                           (vi)  "Trading  Day"  shall  mean a day on which  the
national  securities  exchange  or the NASDAQ  National  Market  System  used to
determine  the  Closing  Price is open for the  transaction  of  business or the
reporting of trades.

                  (i) Dividend or Interest  Reinvestment Plans.  Notwithstanding
the foregoing provisions, the issuance of any shares of Common Stock pursuant to
any plan  providing  for the  reinvestment  of dividends or interest  payable on
securities of the Corporation and the investment of additional  optional amounts
in shares of Common Stock under any such plan, and the issuance of any shares of
Common  Stock or options  or rights to  purchase  such  shares  pursuant  to any
employee  benefit plan or program of the  Corporation or pursuant to any option,
warrant,  right or exercisable,  exchangeable or convertible  security issued or
outstanding on the Original Issue Date (except as expressly  provided in Section
8(c)(i) or 8(c)(ii) with respect to certain events under the Rights  Agreement),
and any  issuance  of Rights  (defined  below) or other  rights  referred  to in
Section 8(c)(x),  shall not be deemed to constitute an issuance of Common Stock,
options,   warrants,   rights,  or  exercisable,   exchangeable  or  convertible
securities by the  Corporation  or any of its  subsidiaries  to which any of the
adjustment  provisions  described  above in this Section 8 applies.  There shall
also be no  adjustment  of the  conversion  price in case of the issuance of any
stock  (or  options,   warrants,  rights,  or  securities  convertible  into  or
exchangeable or exercisable for stock) of the Corporation except as specifically
described  in this  Section 8. If any action  would  require  adjustment  of the
conversion  price pursuant to more than one of the provisions  described  above,
only one  adjustment  shall be made and such  adjustment  shall be the amount of
adjustment  which has the  highest  absolute  value to the  holders  of Series B
Cumulative Convertible Preferred Stock.

                  (j)  Preferred  Share  Purchase  Rights.  So long as Preferred
Share Purchase Rights, of the kind authorized and declared on September 23, 1988
and  distributed by the  Corporation in September 1988 as the same have been and
may hereafter be amended  ("Rights"),  are attached to the outstanding shares of
Common  Stock  of the  Corporation,  each  share of  Common  Stock  issued  upon
conversion  of the shares of Series B  Cumulative  Convertible  Preferred  Stock
prior to the  earliest  of any  Distribution  Date  (as  defined  in the  Rights
Agreement),  the date of  redemption  of the Rights or the date of expiration of
the  Rights  shall be issued  with  Rights in an amount  equal to the  amount of
Rights then attached to each such outstanding share of Common Stock.


                                       25



                  (k) Certain  Additional Rights. In case the Corporation shall,
by dividend  or  otherwise,  authorize,  declare or make a  distribution  on its
Common Stock referred to in Section 8(c)(iv) or Section  8(c)(v),  the holder of
each  share  of  Series  B  Cumulative  Convertible  Preferred  Stock,  upon the
conversion thereof subsequent to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution and prior to
the  effectiveness  of the  conversion  price  adjustment  in  respect  of  such
distribution pursuant to Section 8(c)(iv) or Section 8(c)(v),  shall be entitled
to  receive  for each  share of Common  Stock  into which such share of Series B
Cumulative  Convertible  Preferred  Stock  is  converted,  the  portion  of  the
evidences  of  indebtedness,  shares of stock,  cash and  assets so  distributed
applicable  to one  share of  Common  Stock;  provided,  however,  that,  at the
election of the Corporation  (whose election shall be evidenced by a vote of the
Board of Directors)  with respect to all holders so converting,  the Corporation
may, in lieu of distributing to such holder any portion of such distribution not
consisting of cash or securities of the  Corporation,  pay such holder an amount
in cash equal to the fair market value  thereof (as  determined  by the Board of
Directors,  whose  determination  shall be conclusive and described in a vote of
the Board of  Directors).  If any  conversion  of a share of Series B Cumulative
Convertible  Preferred  Stock described in the  immediately  preceding  sentence
occurs prior to the payment date for a  distribution  to holders of Common Stock
which the holder of the share of Series B Cumulative Convertible Preferred Stock
so converted is entitled to receive in accordance with the immediately preceding
sentence,  the  Corporation  may  elect  (such  election  to be  evidenced  by a
resolution  of the Board of  Directors)  to distribute to such holder a due bill
for the evidences of indebtedness, shares of stock, cash or assets to which such
holder is so  entitled;  provided  that  such due bill (i) meets any  applicable
requirements of the principal  national  securities  exchange or other market on
which the Common Stock is then traded and (ii)  requires  payment or delivery of
such evidences of  indebtedness,  shares of stock,  cash or assets no later than
the date of payment or  delivery  thereof to holders of Common  Stock  receiving
such  distribution.  The rights  provided in this  Section  8(k) with respect to
distribution referred to in Section 8(c)(iv) or Section 8(c)(v) shall be in lieu
of,  and not in  addition  to,  the  rights  accorded  to  holders  of  Series B
Cumulative Convertible Preferred Stock in those Sections.

                  (l) Other. Notwithstanding any other provision in this Section
8 to  the  contrary,  if  the  Corporation  shall,  by  dividend  or  otherwise,
authorize,  declare or make a  distribution  on its Common Stock  referred to in
Section 8(c)(iv) and such  distribution  shall include shares of stock of one or
more  corporations that immediately prior to such distribution was or would have
been a  subsidiary  (a  "Spin-Off"),  the  holder  of each  share  of  Series  B
Cumulative Convertible Preferred Stock shall be entitled to receive its pro rata
share of the  securities  distributed in the Spin-Off as if such holder had been
the  holder of record of the  number of shares of Common  Stock  into  which the
Series B Cumulative Convertible Preferred Stock would be convertible (but for


                                       26



any restrictions on convertibility  contained in this Certificate of Vote) as of
the record date for such distribution.  The rights provided in this Section 8(l)
with  respect  to  Spin-Offs  shall be in lieu of, and not in  addition  to, the
rights  accorded to holders of Series B Cumulative  Convertible  Preferred Stock
with respect to Spin-Offs in Section 8(c)(iv).

         9.       Voting Rights.

                  (a)  General.  The  holders  of shares of Series B  Cumulative
Convertible  Preferred  Stock shall each  initially  have Twenty and  Sixty-Five
Thousand Six Hundred and Forty-Eight  Hundred-Thousandths  (20.65648)  votes for
each share held, which such shares shall be voted as a class with the holders of
the Common  Stock on all matters on which the Common  Stock may vote,  except as
set forth below.  Upon the  occurrence of any event that causes an adjustment to
the conversion  price pursuant to Section 8(c), the number of votes possessed by
each share of Series B Cumulative  Convertible Stock shall be adjusted such that
the number of votes  possessed  by each such share  immediately  after the event
giving rise to the adjustment under Section 8(c) shall be the number, rounded to
the nearest one-hundred thousandth,  equal to the Liquidation Preference divided
by the conversion  price  immediately  after such event.  Any shares of Series B
Cumulative  Convertible  Preferred  Stock held by the  Corporation or any entity
controlled by the Corporation  shall not have voting rights  hereunder and shall
not be counted in determining the presence of a quorum.

                  (b)      Special Default Voting Rights.

                           (i) Whenever a Special Default exists, (1) the number
of members of the Board of  Directors  shall be  increased  by such number as is
necessary  to allow the election of the  directors  specified in clause (2), and
(2) the holders of the Series B Cumulative  Convertible  Preferred Stock, voting
separately  as a class,  shall have the right to elect an  additional  number of
directors to the Board of Directors such that Designated  Directors  selected by
the holders of the Series B Cumulative  Convertible  Preferred  Stock,  plus the
directors  elected  by  such  holders  voting  as a  class  under  this  clause,
constitute a majority of Board.  Notwithstanding  the  foregoing  sentence,  the
holders  of  the  Series  B  Cumulative   Convertible  Preferred  Stock  (voting
separately as a class) will not have the right to vote for additional  directors
pursuant to this Section 9(b) where (x) such holders have exercised  their right
to elect  additional  directors  pursuant  to  Section  7(e)(iii),  and (y) such
additional  directors continue to serve as such. The right of the holders of the
Series B  Cumulative  Convertible  Preferred  Stock to vote for such  additional
directors  shall  terminate  at the  earlier  to occur of (A) when such  Special
Default  no longer  exists or (ii) two years  after the  election  of  directors
pursuant to clause (2) of the first sentence of this Section. The term of office
of all directors so elected shall terminate immediately upon the termination of


                                       27


the right of the holders of the Series B Cumulative  Convertible Preferred Stock
to vote for such additional directors,  and the number of directors of the Board
of Directors shall immediately thereafter be reduced.

                           (ii) The foregoing right of the holders of the Series
B  Cumulative  Convertible  Preferred  Stock  with  respect to the  election  of
additional  directors may be exercised at each annual meeting of stockholders or
at any special  meeting of stockholders  held for such purpose.  If the right to
elect  directors  shall have  accrued to the holders of the Series B  Cumulative
Convertible  Preferred  Stock  more than  thirty  (30) days  preceding  the date
established  for the next annual meeting of  stockholders,  the President of the
Corporation shall, within five (5) days after the delivery to the Corporation at
its principal  office of a written  request for a special  meeting signed by the
holders of at least 10% of all  outstanding  shares of the  Series B  Cumulative
Convertible Preferred Stock, call a special meeting of the holders of the Series
B Cumulative  Convertible  Preferred Stock to be held as promptly as practicable
after the delivery of such request for the purpose of electing  such  additional
directors.

                           (iii)  The   holders  of  the  Series  B   Cumulative
Convertible  Preferred  Stock referred to above voting as a class shall have the
right to remove with or without cause at any time and replace any directors such
holders shall have elected pursuant to this Section 9(c) and the holders of each
other class of stock of the  Corporation  shall not have the right to remove any
such directors.

                  (c) Class Voting Rights. So long as any shares of the Series B
Cumulative  Convertible  Preferred Stock are outstanding,  the Corporation shall
not,  directly or  indirectly,  without the  affirmative  vote or consent of the
holders of at least 66 2/3% (unless a higher  percentage  shall then be required
by applicable law or the  Corporation's  Articles) of all outstanding  shares of
the Series B  Cumulative  Convertible  Preferred  Stock voting  separately  as a
class: (i) amend, alter or repeal any provision of the Articles,  Certificate of
Vote, or the bylaws of the Corporation, if such amendment,  alteration or repeal
would alter the contract rights,  as expressly set forth herein, of the Series B
Cumulative  Convertible  Preferred  Stock or otherwise  to adversely  affect the
rights of the holders  thereof or the holders of the Common Stock,  (ii) create,
authorize  or  issue,  or amend the terms of in a manner  adversely  affect  the
rights of the holders the Series B Cumulative  Convertible  Preferred  Stock, or
reclassify  shares of any authorized stock of the Corporation  into, or increase
the authorized amount of, any Senior Dividend Stock,  Senior  Liquidation Stock,
Parity Dividend Stock, or Parity  Liquidation Stock or any security  convertible
into such senior or Parity Stock, or (iii) approve a Fundamental Change.


                                       28


         10.  Outstanding  Shares. For purposes of this Certificate of Vote, all
shares  of  Series  B  Cumulative  Convertible  Preferred  Stock  issued  by the
Corporation  shall be  deemed  outstanding  except  (i) from the date  fixed for
redemption  pursuant  to  Section 6 hereof,  all  shares of Series B  Cumulative
Convertible  Preferred  Stock  that  have been so called  for  redemption  under
Section 6, to the extent provided thereunder; (ii) from the date of surrender of
certificates  representing shares of Series B Cumulative  Convertible  Preferred
Stock, all shares of Series B Cumulative  Convertible  Preferred Stock converted
into Common Stock or  repurchased  pursuant to Section 7 hereof;  and (iii) from
the date of  registration  of  transfer,  all  shares  of  Series  B  Cumulative
Convertible   Preferred   Stock  held  of  record  by  the  Corporation  or  any
majority-owned subsidiary of the Corporation.

         11.      Transfer Restrictions.

                  (a) Legends on Series B Cumulative Convertible Preferred Stock
and Common Stock.  The certificates  representing  shares of Series B Cumulative
Convertible  Preferred Stock shall,  unless  otherwise agreed by the Corporation
and the holders of any such  certificates,  bear a legend  substantially  to the
following effect:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE AND ANY SECURITIES ISSUABLE
         UPON  CONVERSION  OR EXCHANGE  HEREOF MAY NOT BE OFFERED OR SOLD EXCEPT
         PURSUANT  TO  (i)  AN  EFFECTIVE   REGISTRATION   STATEMENT  UNDER  THE
         SECURITIES   ACT  OF  1933,  OR  (ii)  AN  APPLICABLE   EXEMPTION  FROM
         REGISTRATION  THEREUNDER.  ANY  SALE  PURSUANT  TO  CLAUSE  (ii) OF THE
         PRECEDING  SENTENCE  MUST  BE  ACCOMPANIED  BY AN  OPINION  OF  COUNSEL
         REASONABLY  SATISFACTORY TO PERINI  CORPORATION TO THE EFFECT THAT SUCH
         EXEMPTION FROM  REGISTRATION IS AVAILABLE IN CONNECTION WITH SUCH SALE.
         IN  ADDITION,  THE  VOTING,  SALE,  ASSIGNMENT,   TRANSFER,  PLEDGE  OR
         HYPOTHECATION OF THE SHARES  REPRESENTED BY THIS CERTIFICATE IS FURTHER
         SUBJECT TO RESTRIC TIONS WHICH ARE  CONTAINED IN THE RESTATED  ARTICLES

         PERINI  CORPORATION  AND WILL BE  FURNISHED BY THE  CORPORATION  TO THE
         STOCKHOLDER ON REQUEST AND WITHOUT CHARGE."


                                       29



                  (b) Transfer Agent Requirements. The transfer agent (which may
be the  Corporation)  for the Series B Cumulative  Convertible  Preferred  Stock
shall not be  required  to accept for  registration  of  transfer  any shares of
Series B Cumulative  Convertible Preferred Stock bearing the legend contained in
paragraph  (a) above,  except  upon  presentation  of evidence  satisfactory  to
transfer  agent  that the  restrictions  on  transfer  of shares of the Series B
Cumulative  Convertible  Preferred  Stock referred to in the legend in paragraph
(a) have been complied with, all in accordance with such reasonable  regulations
as the  Corporation  may from time to time  agree  with the  transfer  agent for
shares of the Series B Cumulative Convertible Preferred Stock.

         12.  Status  of  Acquired   Shares.   Shares  of  Series  B  Cumulative
Convertible Preferred Stock redeemed or repurchased by the Corporation, received
upon conversion  pursuant to Section 8 or otherwise  acquired by the Corporation
will be restored to the status of  authorized  but unissued  shares of Preferred
Stock, without designation as to class, and may thereafter be issued, but not as
shares of Series B Cumulative Convertible Preferred Stock.

         13.      Special Covenants.

                  (a)  Nomination  of  Directors.  Effective  as of the Original
Issue  Date,  the  Corporation  shall  elect  to the  board of  directors  three
directors designated by the holders of such stock (such directors, together with
their replacements as provided below, the "Designated  Directors"),  one of whom
shall be a Class I director,  one of whom shall be a Class II director,  and one
of whom shall be a Class III director. The holders of a majority of the Series B
Cumulative  Convertible  Preferred  Stock  shall  designate  the classes of such
initial Designated Directors.

                           (i) In the event that any  Designated  Director shall
resign,  be unable to serve, or be removed (a "Replaced  Designated  Director"),
the holders of a majority of the Series B Cumulative Convertible Preferred Stock
shall have the right to designate a replacement to serve as Designated  Director
until the next meeting of  shareholders  at which directors of the same class as
the Replaced  Designated  Director are elected.  Any Designated  Director may be
removed from the Board,  with or without cause,  by the holders of a majority of
the Series B Cumulative Convertible Preferred Stock.

                           (ii) Except as provided  below,  at any time when the
term of a Designated  Director  shall have ended and there shall be a meeting of
shareholders  of the  Corporation  to elect  directors,  the  Corporation  shall
nominate  for  election  to  the  board  of  directors,  as a  successor  to any
Designated  Director  serving  pursuant  to Section  13(a) or clause (i) of such
provision,  such  person as is  designated  to be a  Designated  Director by the
holders of a majority of the Series B Cumulative Convertible Preferred Stock.


                                       30


                           (iii) In the event  that the  holders of the Series B
Cumulative  Convertible  Preferred  Stock  dispose of such  stock or  Conversion
Shares (defined below)  representing more than sixty-six and two-thirds  percent
(66-2/3%) and less than or equal to eighty  percent (80%) of the voting power of
the Series B Cumulative Convertible Preferred Stock issued on the Original Issue
Date (plus any payment-in-kind dividends paid thereon), the number of Designated
Directors  shall be reduced to two.  If there are then more than two  Designated
Directors  serving on the  board,  the  holders  of a  majority  of the Series B
Cumulative Convertible Preferred Stock shall remove one such Designated Director
and the holders of such stock shall not have any right,  pursuant to clause (ii)
or otherwise,  to cause the  Corporation  to nominate a designated  successor to
such removed director.

                           (iv) In the event  that the  holders  of the Series B
Cumulative  Convertible  Preferred  Stock  dispose of such  stock or  Conversion
Shares representing more than eighty percent (80%) and less than or equal ninety
percent  (90%) of the  voting  power  of the  Series  B  Cumulative  Convertible
Preferred  Stock  issued on the  Original  Issue Date (plus any  payment-in-kind
dividends paid thereon),  the number of Designated Directors shall be reduced to
one. If there is then more than one  Designated  Director  serving on the board,
the holders of a majority of the Series B Cumulative Convertible Preferred Stock
shall remove all but one such Designated  Director and the holders of such stock
shall not have any right,  pursuant  to clause (ii) or  otherwise,  to cause the
Corporation to nominate a designated successor to such removed director(s).

                           (v) In the event  that the  holders  of the  Series B
Cumulative  Convertible  Preferred  Stock  dispose of such  stock or  Conversion
Shares  representing  more than ninety  percent (90%) of the voting power of the
Series B Cumulative  Convertible  Preferred  Stock issued on the Original  Issue
Date  (plus any  payment-in-kind  dividends  paid  thereon),  there  shall be no
Designated  Directors  and any  Designated  Directors  then serving on the board
shall be removed,  and their terms in office shall immediately  expire,  without
any further action of the holders of such stock.

                           (vi) The right to nominate directors pursuant to this
provision  is in addition  to, and not in  limitation  of, any other  rights and
powers  of the  Series  B  Cumulative  Convertible  Preferred  Stock.  Directors
nominated by the holders of the Series B Cumulative  Convertible Preferred Stock
in their  capacity  as  holders  of  capital  stock of the  Corporation  and not
pursuant to clause (i),  (ii), or (iii) above are not  Designated  Directors for
purposes of this Certificate of Vote.

                           (vii) The vote of the holders of Series B  Cumulative
Convertible Preferred Stock referred to in this Section may be exercised at a


                                       31


meeting  of such  holders or by written  consent of holders  with the  requisite
percentage of the voting power outstanding.

                           (viii)   Upon   the   reasonable   request   of   the
Corporation,  the holders of the Series B Cumulative Convertible Preferred Stock
shall certify in writing to the Corporation their holding of Conversion Shares.

                           (ix)     For purposes of this Section:

                                    (1) "voting  power" shall mean the number of
votes each such share possesses in the election of directors; and

                                    (2)  "Conversion   Shares"  shall  mean  the
shares of Common Stock which are both (A) issuable or issued upon  conversion of
the Series B Cumulative  Convertible  Preferred  Stock  pursuant to the terms of
this  Certificate of Vote of Directors,  and (B) held by a person who either (x)
acquired the shares of the Series B Cumulative  Convertible Preferred Stock from
which the shares referred to in clause (A) of this definition were converted and
has held such Common Stock continuously  thereafter,  or (y) acquired the shares
referred to in clause (A) of this definition from a person referred to in clause
(B)(x)  of this  definition  through  a  distribution  to the  partners  by,  or
dissolution of, a partnership.

                  (b) Appointment to Executive  Committee.  At any time at which
the holders of the Series B Cumulative  Convertible  Preferred  Stock shall have
the right to nominate  directors  for election to the board  pursuant to Section
13(a) hereof,  such holders shall also have the right to designate a like number
of persons from among the members of the board of directors to be members of the
Executive Committee of the board (the "Designated Executive Committee Members").
In the event that any Designated  Executive  Committee  Member shall resign,  be
unable to serve,  or be  removed,  the  holders  of a  majority  of the Series B
Cumulative  Convertible  Preferred  Stock  shall have the right to  designate  a
replacement  Designated  Executive  Committee Member.  Any Designated  Executive
Committee  Member may be removed from the Executive  Committee,  with or without
cause,  by the  holders of a majority  of the  Series B  Cumulative  Convertible
Preferred Stock.

                  (c) Approval of Certain  Actions.  Neither the Corporation nor
the Board shall take any of the  following  actions  without  the  approval of a
majority  of the  members  of the  Executive  Committee  of the  Board:  (A) any
borrowing or guarantee by the Corporation  exceeding $15 million, (B) except for
issuance of stock or stock options pursuant to (x) the  Corporation's  incentive
compensation  plans and programs,  (y) any warrants  outstanding on the Original
Issue  Date,  or (z) the  Rights,  any  issuance  of stock  (whether  common  or
preferred,  whether voting or non-voting,  whether junior, pari passu, or senior
to the Series B Cumulative Convertible Preferred Stock) other


                                       32



than Common Stock in an aggregate  amount not exceeding five percent (5%) of the
Common  Stock  issued  and  outstanding  on the  Original  Issue  Date,  (C) any
strategic alliance (other than a construction joint venture) involving a capital
commitment by the  Corporation  exceeding $5 million,  (D) any asset sale by the
Corporation or lease by it as lessor  exceeding $5 million (other than equipment
dispositions in the normal course of business);  (E) any redemption or amendment
of the  Rights  or the  preferred  stock of the  Corporation  issuable  upon the
exercise of such Rights, or any amendment of the Rights  Agreement;  and (F) any
termination  of (other than a termination  upon  expiration) or amendment to the
management  agreement  among the  Corporation,  Ronald  Tutor  and  Tutor-Saliba
Corporation;  provided,  however,  that  for  purposes  of this  Section  13(c),
approval of the  Executive  Committee  shall not be required for any decision by
the Board of Directors to redeem the Series B Cumulative  Convertible  Preferred
Stock  pursuant to Section 6(a).  Notwithstanding  the foregoing  sentence,  the
board of directors of the Corporation  may take any of the actions  specified in
the preceding sentence if, after having consulted with and considered the advice
of outside counsel, it has reasonably  determined in good faith that the failure
of the board to take such  action  would be likely to cause the  members of such
board to breach their fiduciary duties under applicable law.

         14.  Severability  of  Provisions.  Whenever  possible,  each provision
hereof  shall be  interpreted  in a manner as to be  effective  and valid  under
applicable  law,  but if any  provision  hereof is held to be  prohibited  by or
invalid under  applicable law, such provision  shall be ineffective  only to the
extent of such  prohibition or  invalidity,  without  invalidating  or otherwise
adversely  affecting the remaining  provisions  hereof.  If a court of competent
jurisdiction  should  determine  that a  provision  hereof  would  be  valid  or
enforceable  if a period of time were  extended  or  shortened  or a  particular
percentage were increased or decreased,  then such court may make such change as

                    STOCK ASSIGNMENT AND ASSUMPTION AGREEMENT

         This Stock Assignment and Assumption Agreement ("Assignment Agreement")
is entered into this 17th day of January 1997, by and among PB Capital Partners,
L.P.,  a  Delaware  limited  partnership  ("Assignor"),   The  Common  Fund  for
Non-Profit  Organizations  ("Assignee"),  Richard  C.  Blum &  Associates,  L.P.
("RCBA"), and Perini Corporation ("Seller").

         WHEREAS,  Assignor is a party to a Stock Purchase and Sale Agreement by
and among Assignor,  Seller,  and RCBA,  dated July 24, 1996,  together with all
exhibits and schedules  thereto and all  amendments  and  modifications  thereof
(collectively referred to as the "Stock Purchase Agreement"),  pursuant to which
Assignor  agreed to purchase  150,150 shares of newly issued Series B Cumulative
Convertible  Preferred Stock, par value $1.00 per share (the "Series B Preferred
Stock"), of Seller for $30,030,000;

         WHEREAS,  Assignor wishes to assign to Assignee, and Assignee wishes to
accept  assignment from Assignor,  (i) all of Assignor's  rights and obligations
under the Stock  Purchase  Agreement to purchase  from Seller  23,300  shares of
Series B Preferred Stock of Seller (the "Assigned  Shares"),  and (ii) all other
rights, remedies, and obligations of Assignor under the Stock Purchase Agreement
with respect to the Assigned Shares;

         WHEREAS,  pursuant to an Investment  Management  Agreement between RCBA
and  Assignee,   dated  July  1,  1993,  RCBA  is  the  investment  manager  and
attorney-in-fact for the Assignee with respect to certain investments;

         NOW, THEREFORE,  in consideration of the premises and of the respective
representations,  warranties,  covenants,  agreements and  conditions  contained
herein and other good and valuable  consideration the receipt and sufficiency of
which is hereby acknowledged, each of the parties agrees as follows:

         1.       Assignment and Assumption.

         (a) Upon the terms and subject to the conditions  appearing herein, the
Assignor  hereby  transfers,  assigns  and  delegates  to  the  Assignee  all of
Assignor's rights, title, interest, remedies, duties and obligations relating to
the  purchase  of  the  Assigned  Shares  under  the  Stock  Purchase  Agreement
(collectively, the "Assigned Rights").

         (b) Upon the terms and subject to the conditions  appearing  herein, on
the basis of the  representations,  warranties  and  covenants  of Seller in the
Stock Purchase Agreement,  Assignee hereby accepts the foregoing  assignment and
delegation and, in addition,  expressly assumes and agrees to keep,  perform and
fulfill all of the terms, covenants,  conditions, duties and obligations insofar
as they relate to the Assignee's purchase of the Assigned Shares of the Series B
Preferred  Stock which are required to be kept,  performed  and fulfilled by the
Assignor  pursuant to the Stock  Purchase  Agreement  from and after the date of
this Assignment. Assignor represents and







warrants that it has delivered to Assignee a true and complete copy of the Stock
Purchase Agreement.

         (c)      Assignor, Assignee and Seller hereby agree as follows:

                  (1) All  obligations  of Assignor and Assignee under the Stock
Purchase  Agreement  shall be several,  and Assignee  and Assignor  shall not be
jointly obligated in any respect.

                  (2) All  covenants,  duties,  obligations  and  liabilities of
Assignee  arising  under  the  Stock  Purchase  Agreement  as a  result  of this
Agreement shall be limited to the covenants, duties, obligations and liabilities
that relate to the  Assigned  Shares.  Without  limiting the  generality  of the
immediately  preceding  sentence,  neither  Assignee nor Assignor shall have any
responsibility  for any breach or  default,  or failure in  performance,  of the
other under the Stock Purchase Agreement.

                  (3)  Except as  hereinafter  provided,  wherever  in the Stock
Purchase  Agreement  there is any  reference to  "Purchaser",  as defined in the
Stock  Purchase  Agreement,  that  reference  shall  mean  and  refer to each of
"Purchaser" and "The Common Fund for NonProfit  Organizations." Without limiting
the  generality of the  foregoing,  (i) all  obligations of Seller to Purchaser,
including,   without  limitation,   those  arising  under  the  representations,
warranties  and  covenants  of Seller in, or as  provided  for under,  the Stock
Purchase  Agreement,  shall  be to each  of  Assignor  and  Assignee,  (ii)  all
approvals,  agreements,  consents  and  waivers  of  Purchaser  under  the Stock
Purchase  Agreement  must be given by each of Assignor and  Assignee,  (iii) all
disclosures  that  Seller  is  required  to make to  Purchaser  under  the Stock
Purchase  Agreement  or  applicable  law and all  information  that  Seller must
provide to Purchaser  must be made and provided to Assignor  and  Assignee,  and
(iv) the Stock  Purchase  Agreement  may not be amended or modified  without the
written consent of each of Assignor and Assignee.

                  (4) Assignee shall not make any  representations or warranties
of Assignor under Article VI of the Stock Purchase  Agreement.  RCBA  represents
and warrants to Seller that it has all requisite power and authority to execute,
deliver, and perform this Agreement on behalf of Assignee.

                  (5)  Seller  shall  take  reasonable   measures  to  establish
procedures to deal with,  and minimize the effects of,  conflicts of interest of
directors  and officers of Seller and shall from time to time  provide  Assignee
with such information  with respect to such procedures and their  application to
specific circumstances as Assignee may reasonably request.

                  (6) All notices to Assignee under the Stock Purchase Agreement
shall be given in the manner provided in Section 14.1 thereof and to Assignee as
follows:

                           Facsimile: 415-434-3130

                  (7)  Assignee's  obligation  to purchase the  Assigned  Shares

3(d) hereof being true and correct as of the Closing Date.

                  (8)  The  Stock  Purchase   Agreement  is  hereby  amended  to
incorporate  the  foregoing  provisions  of  this  Section  1(c)  to the  extent
necessary  to give  effect to such  provisions  and to avoid  any  inconsistency
between such provisions and the Stock Purchase Agreement.

         2.  Modification.  This  Assignment  Agreement  shall not be  modified,
discharged or terminated  except by an instrument in writing signed by the party
against whom any waiver, change, discharge or termination is sought.

Assignment  Agreement  shall be  binding  upon and inure to the  benefit  of the
parties  and  their  heirs,  executors,  administrators,  successors  and  legal
representatives,  except  that such  enforcement  may be subject to  bankruptcy,
insolvency,  reorganization,  moratorium, or other similar laws now or hereafter
in effect  relating to  creditors'  rights and general  principles of equity and
except to the extent that rights to indemnity and contribution may be limited by
federal or state securities laws or policies underlying such laws.

Purchase Agreement,  the Registration Rights Agreement,  the Certificate of Vote
of Directors with respect to the Series B Preferred Stock and the  Shareholders'
Agreement  constitute  the entire  agreement  of the  parties,  and there are no
representations,  covenants or other agreements  except as stated or referred to
herein.

         6.  Assignability.  This  Assignment  Agreement is not  transferable or
assignable by any party hereto.


                                      - 3 -

construed in accordance  with the laws of the State of Delaware,  without giving
effect to the principles of the conflicts of laws thereof.

         8. Counterparts.  This Assignment Agreement may be executed through the
use of separate  signature pages or in any number of  counterparts,  and each of
such counterparts  shall, for all purposes,  constitute one agreement binding on
all the parties,  notwithstanding  that all parties are not  signatories  to the
same counterpart.

                                VOTING AGREEMENT


         THIS VOTING AGREEMENT, dated as of January 17, 1997 (this "Agreement"),
is by and among PB  CAPITAL  PARTNERS,  L.P.,  a  Delaware  limited  partnership
("PB"),  PERINI CORPORATION,  a Massachusetts  corporation (the  "Corporation"),
DAVID B. PERINI ("D. Perini"),  PERINI MEMORIAL  FOUNDATION (the  "Foundation"),
DAVID B. PERINI TESTAMENTARY TRUST (the "Trust"), RONALD N. TUTOR ("Tutor"), and
TUTOR-SALIBA CORPORATION  ("Tutor-Saliba").  PB, D. Perini, the Foundation,  the
Trust,  Tutor,  and  Tutor-Saliba  are  referred to  collectively  herein as the
"Stockholders" and each individually as a "Stockholder."

         WHEREAS,  each  Stockholder is the record and  beneficial  owner of (1)
that  number  of  shares of Common  Stock,  par value  $1.00 per share  ("Common
Stock"),  (2) that number of Series B  Cumulative  Convertible  Preferred  Stock
("Series B  Cumulative  Convertible  Preferred  Stock"),  and (3) that number of
Series A Junior  Participating  Cumulative  Preferred  Stock  ("Series  A Junior
Participating Stock") of the Corporation,  set forth opposite such Stockholder's
name on  Exhibit A  attached  hereto  (the  Common  Stock,  Series B  Cumulative
Convertible  Preferred Stock, and Series A Junior Participating Stock,  together
with  any  other  series  or  classes  of  voting  stock  to be  issued  by  the
Corporation, collectively the "Perini Voting Stock"); and

         WHEREAS,  pursuant to a Stock Purchase and Sale Agreement,  dated as of
July 24, 1996, as amended,  by and among PB, Richard C. Blum & Associates,  L.P.
("RCBA") and the Corporation (the "Stock Purchase  Agreement"),  the Corporation
has agreed to sell to PB, and PB has agreed to  purchase  from the  Corporation,
150,150  shares  of  Series  B  Cumulative   Convertible   Preferred   Stock  in
consideration for the payment to the Corporation of $30,030,000.00; and

         WHEREAS, PB has made the execution of this Voting Agreement a condition
to the purchase of the shares of Series B Cumulative Convertible Preferred Stock
and regards  this Voting  Agreement  as integral to the  economic  value of such
securities; and

         WHEREAS,  PB (together  with certain of its assigns) is  simultaneously
purchasing such securities; and

         WHEREAS,  in  order to  induce  PB to enter  into  the  Stock  Purchase
Agreement,  the  Stockholders  desire to enter into this Agreement,  which shall
inure to the benefit of PB;






                                      - 2 -




         NOW, THEREFORE, for and in consideration of $10.00 and the premises and
mutual covenants and agreements hereinafter  contained,  the Stockholders hereby
agree as follows:

         1. Voting of Shares for Election of Directors.  Each Stockholder hereby
agrees to vote or cause to be voted all Perini  Voting  Stock owned or hereafter
acquired  by him or it,  or  over  which  he or it has  voting  control  in such
Stockholder's  own right,  in favor of the election to the Board of Directors of
the  representative  designated  by PB at the next annual or special  meeting of
stockholders  at which  directors  will be elected  ("Meeting"),  which Director
shall serve until his  successor  is elected and  qualified or until his earlier
resignation  or  removal.  At any time  during the term of this  Agreement,  the
Corporation shall cause the nomination for election to the Board of Directors of
the  representatives of PB designated in accordance with the Certificate of Vote
of  directors  setting  forth the terms of the Series B  Cumulative  Convertible
Preferred Stock, and shall call such stockholders'  meetings as may be necessary
or requested by PB to effect any such election.  The representatives  designated
by PB shall be reasonably satisfactory to the Corporation.

         2.  Term.  This  Agreement  shall  remain  in force  and  effect  until
immediately  after  the  holding  of the  next  Meeting  at which  the  Director
designated pursuant to Section 1 is elected.

         3. Changes in Common Stock. In the event that subsequent to the date of
this  Agreement  any  shares  or other  securities  (other  than any  shares  or
securities of another  corporation issued to the stockholders of the Corporation
pursuant  to a plan of merger)  are issued on, or in  exchange  for,  any of the
shares of the  Perini  Voting  Stock held by the  Stockholders  by reason of any
stock  dividend,  stock split,  consolidation  of shares,  reclassification,  or
consolidation  involving the  Corporation,  such shares or  securities  shall be
deemed to be Perini Stock for purposes of this Agreement.

         4. Representations of Stockholders.  Each Stockholder hereby represents
and warrants  that (i) he owns and has the right to vote the number of shares of
the  Perini  Voting  Stock set forth  opposite  his name on  Exhibit A  attached
hereto,  (ii)  each of the  Stockholders  has  full  power to  enter  into  this
Agreement  and  has  not,  prior  to the  date of this  Agreement,  executed  or
delivered  any proxy or  entered  into any other  voting  agreement  or  similar
arrangement  that  would  conflict  with  the  purposes  or  provisions  of this
Agreement,  and (iii) he will not take any action inconsistent with the purposes
and provisions of this Agreement.

         5.  Enforceability;  Validity.  Irreparable  damage would result in the
event that the  provisions  of this  Agreement  are not  specifically  enforced.
Therefore,  the  rights  to, or  obligations  of, the  parties  hereto  shall be
enforceable  in a court  of  equity  by a decree  of  specific  performance  and
appropriate  injunctive  relief may be  applied  for and  granted in  connection
therewith. Such remedies, and all other remedies provided for in this Agreement,
shall,  however, be cumulative and not exclusive and shall be in addition to any
other remedies which any party may have under this Agreement or otherwise.




                                      -3-


         6.  Benefit.  Subject to the  provisions  of Section 9, this  Agreement
shall be binding  upon,  and inure to the  benefit  of, the  respective  parties
hereto and their successors, assigns, and transferees.

         7. Governing Law. This Agreement shall be governed by and construed and
enforced  in  accordance  with the  laws of the  Commonwealth  of  Massachusetts
applicable  to  agreements  made  and  to  be  performed   entirely  within  the
Commonwealth of Massachusetts

         8.  Counterparts.  This  Agreement  may be  executed  in  one  or  more
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together shall constitute one and the same instrument.

         9. Legending. Upon the execution of this Agreement, each certificate or
other instrument for Perini Voting  Securities now registered or to be issued in
the  name  of  the  Stockholders  shall  be  endorsed  by the  Secretary  of the
Corporation as follows:

         "This  certificate is subject to that certain Voting Agreement dated as
         of January  17,  1997 by and among the  Corporation  and certain of the
         holders of its voting  stock,  a copy of which is on file in the office
         of the  Corporation  and is available  upon request of any  Stockholder
         without charge."

Provided,  however,  that each of the Trust and the Foundation shall be entitled
to withhold from the legending  required by this Section up to ten percent (10%)
of its  Perini  Voting  Stock  and  that  such  stock  -- if  disposed  of to an
unaffiliated  third  party  prior to the Meeting -- shall not be subject to this
Voting Agreement.

         10. Terms. All terms not otherwise defined in this Agreement shall have
the meaning set forth in the Stock Purchase Agreement.


                                      -4-



         IN WITNESS WHEREOF,  each of the parties has executed this Agreement as
of the date first above written.

                               REGISTRATION RIGHTS

              SECTION 2.1 Shelf Registration.

              (a) As soon as  practicable  but in any event  not later  than the
date (the "Filing Date") that is sixty (60) days after receipt by the Company of
a written  request by the holder or  holders  of a majority  of all  outstanding
Conversion  Shares and Series B Preferred Stock (such majority  determined,  for
purposes of this Section 2.1, based on the aggregate number of Conversion Shares
then outstanding plus the number of Conversion Shares into which any outstanding
shares  of  Series B  Preferred  Stock are then  convertible)  (the  "Initiating
Holders"),  the  Company  shall  prepare  and file  with the SEC a  Registration
Statement for an offering to be made on a delayed or continuous  basis  pursuant
to Rule 415 of the  Securities  Act (a  "Shelf  Registration")  registering  the
resale  from  time to  time by the  holders  thereof  of all of the  Registrable
Securities  upon and following  conversion of the Series B Preferred  Stock (the
"Initial  Shelf  Registration").   The  Registration  Statement  for  any  Shelf
Registration  shall  be on  Form  S-3 or  another  appropriate  form  permitting
registration  of such  Registrable  Securities for resale by such holders in the
manner or manners designated by them (including, without limitation, one or more
Underwritten  Offerings).  The Company shall use its reasonable efforts to cause
the Initial Shelf  Registration to become  effective under the Securities Act as
promptly  as  is  practicable  and  to  keep  the  Initial  Shelf   Registration
continuously   effective   under  the  Securities  Act  until  the  end  of  the
Effectiveness Period.

              (b) If the Initial  Shelf  Registration  or any  Subsequent  Shelf
Registration  (as defined  below)  ceases to be effective  for any reason at any
time  during the  Effectiveness  Period  (other  than  because  all  Registrable
Securities  shall  have  been  sold  or  shall  have  ceased  to be  Registrable
Securities),  the Company shall use all reasonable  efforts to obtain the prompt
withdrawal of any order suspending the effectiveness  thereof,  and in any event
shall  within  thirty days of such  cessation of  effectiveness  amend the Shelf
Registration  in a manner  reasonably  expected to obtain the  withdrawal of the
order  suspending  the  effectiveness  thereof,  or  file  an  additional  Shelf
Registration covering all of the Registrable Securities (a "Subsequent Shelf

                                        5





Registration").  If a Subsequent Shelf  Registration is filed, the Company shall
use all reasonable  efforts to cause the Subsequent Shelf Registration to become
effective  as  promptly  as is  practicable  after such  filing and to keep such
Registration Statement continuously effective until the end of the Effectiveness
Period.

              (c) The Company shall supplement and amend the Shelf  Registration
if  required  by  the  rules,  regulations  or  instructions  applicable  to the
registration form used by the Company for such Shelf  Registration,  if required
by  the  Securities  Act,  or if  reasonably  requested  by  any  holder  of the
Registrable Securities covered by such Registration Statement or by any Managing
Underwriter of such Registrable Securities.

              (d) Each Series B Securityholder  agrees that if it wishes to sell
any  Registrable  Securities  pursuant  to  a  Shelf  Registration  and  related
Prospectus,  it will do so only in  accordance  with this Section  2.1(d).  Each
holder of Registrable Securities agrees to give written notice to the Company at
least six  Business  Days  prior to any  intended  distribution  of  Registrable
Securities under the Shelf Registration,  which notice shall specify the date on
which such holder intends to begin such  distribution  and any information  with
respect to such holder and the intended  distribution of Registrable  Securities
by such holder required to amend or supplement the  Registration  Statement with
respect to such intended distribution of Registrable  Securities by such holder;
provided that no holder may give such notice  unless such notice,  together with
notices given by other holders of Registrable  Securities joining in such notice
or giving similar notices, covers at least 30,000 Conversion Shares. As promptly
as is  practicable  after the date such  notice  is  provided,  and in any event
within five Business Days after such date, the Company shall either:

              (i) (A) prepare and file with the SEC a  post-effective  amendment
     to the Shelf  Registration  or a supplement to the related  Prospectus or a
     supplement or amendment to any document  incorporated  therein by reference
     or any other required  document,  so that such Registration  Statement will
     not  contain  any untrue  statement  of a material  fact or omit to state a
     material  fact  required  to be stated  therein  or  necessary  to make the
     statements therein not misleading,  and so that, as thereafter delivered to
     purchasers  of the  Registrable  Securities  being  sold  thereunder,  such
     Prospectus will not contain any untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein, in light of the circumstances under which they were
     made,  not  misleading;  (B)  provide  each  Notice  Holder  a copy  of any
     documents  filed  pursuant  to Section  2.1(d)(i)(A);  and (C) inform  each
     Notice Holder that the Company has complied with its obligations in Section
     2.1(d)(i)(A) and that the Registration Statement and related Prospectus may
     be  used  for  the  purpose  of  selling  all or any  of  such  Registrable
     Securities (or that, if the Company has filed a post-effective amendment to
     the Shelf  Registration  which  has not yet been  declared  effective,  the
     Company  will  notify  each  Notice  Holder  to that  effect,  will use all
     reasonable  efforts  to secure  the  effectiveness  of such  post-effective
     amendment and will immediately so notify each Notice Holder when the

                                        6





     amendment has become effective); each Notice Holder will sell all or any or
     such Registrable  Securities pursuant to the Shelf Registration and related
     Prospectus only during the 45-day period  commencing with the date on which
     the  Company  gives  notice,  pursuant  to Section  2.1(d)(i)(C),  that the
     Registration  Statement and  Prospectus  may be used for such purpose (such
     45-day  period is referred to as a "Selling  Period");  each Notice  Holder
     agrees  that it will not sell any  Restricted  Securities  pursuant to such
     Registration  Statement or  Prospectus  after such Selling  Period  without
     giving a new notice of intention to sell pursuant to Section  2.1(d) hereof
     and  receiving  a further  notice  from the  Company  pursuant  to  Section
     2.1(d)(i)(C) hereof; or

              (ii) if,  in the  judgment  of the  Company,  it is  advisable  to
     suspend use of the Prospectus for a period of time due to pending  material
     corporate  developments  or similar  material events that have not yet been
     publicly  disclosed and as to which the Company believes public  disclosure
     will be prejudicial to the Company, the Company shall deliver a certificate
     in writing,  signed by its Chief Executive Officer, Chief Financial Officer
     or General  Counsel,  to the Notice  Holders,  the Special  Counsel and the
     Managing  Underwriters,  if any, to the effect of the  foregoing  and, upon
     receipt of such certificate,  each such Notice Holder's Selling Period will
     not  commence  until  such  Notice  Holder's   receipt  of  copies  of  the
     supplemented  or amended  Prospectus  provided for in Section  2.1(d)(i)(A)
     hereof,  or  until  it is  advised  in  writing  by the  Company  that  the
     Prospectus  may be used,  and has  received  copies  of any  additional  or
     supplemental  filings  that are  incorporated  or  deemed  incorporated  by
     reference in such Prospectus.  The Company will use all reasonable  efforts
     to ensure that the use of the  Prospectus  may be resumed,  and the Selling
     Period will  commence,  upon the earlier of (x) public  disclosure  of such
     pending material  corporate  development or similar material event or (y) a
     determination  by the Company that, in the judgment of the Company,  public
     disclosure of such material corporate development or similar material event
     would not be prejudicial to the Company. Notwithstanding the foregoing, the
     Company shall not under any circumstances be entitled to exercise its right
     under this Section  2.1(d) to defer the  commencement  of a Selling  Period
     more  than  one  time  in  any  three-month  period  or  two  times  in any
     twelve-month  period, and the period in which a Selling Period is suspended
     shall not exceed  fifteen  days  unless the Company  shall  deliver to such
     Notice Holders a second  certificate  to the effect set forth above,  which
     shall have the effect of  extending  the period  during  which such Selling
     Period is deferred by up to an  additional  fifteen  days,  or such shorter
     period of time as is  specified  in such  second  certificate.  In no event
     shall the  Company be  permitted  to extend the  period  during  which such
     Selling Period is deferred from and after the date a Notice Holder provides
     notice  to the  Company  in  accordance  with  this  Section  2.1(d) of its
     intention to distribute Registrable Securities (a "Deferral Period") beyond
     such 30-day period.

Registration  Statements  on any  appropriate  form  under  the  Securities  Act
available for the sale of the  Registrable  Securities by the holders thereof in
accordance with the intended method or methods of distribution  thereof, and use
its  reasonable  efforts to cause  each such  Registration  Statement  to become
effective and remain effective as provided herein;  provided, that before filing
any such  Registration  Statement or Prospectus or any amendments or supplements
thereto  (other  than  documents  that  would be  incorporated  or  deemed to be
incorporated therein by reference and that the Company is required by applicable
securities  laws or stock  exchange  requirements  to file)  the  Company  shall
furnish to the Initial Stockholders, the Initiating Holders, the Special Counsel
and the  Managing  Underwriters  of such  offering,  if any,  copies of all such
documents proposed to be filed, which documents will be subject to the review of
the Initial  Stockholders,  the Initiating Holders, the Special Counsel and such
Managing  Underwriters,  and the  Company  shall not file any such  Registration
Statement or  amendment  thereto or any  Prospectus  or any  supplement  thereto
(other than such documents which,  upon filing,  would be incorporated or deemed
to be  incorporated  by  reference  therein  and that the Company is required by
applicable  securities laws or stock exchange requirements to file) to which the
holders of a majority of the Registrable Securities covered by such Registration
Statement,  the  Initial  Stockholders,  the  Initiating  Holders or the Special
Counsel shall reasonably object in writing within two full Business Days.

              (b)   Prepare   and  file  with  the  SEC  such   amendments   and
post-effective  amendments to each Registration Statement as may be necessary to
keep such  Registration  Statement  continuously  effective  for the  applicable
period specified in Section 2.1; cause the related Prospectus to be supplemented
by any  required  Prospectus  supplement,  and as so  supplemented  to be  filed
pursuant  to Rule  424 (or any  similar  provisions  then in  force)  under  the
Securities  Act;  and comply  with the  provisions  of the  Securities  Act with
respect  to the  disposition  of all  securities  covered  by such  Registration
Statement  during the applicable  period in accordance with the intended methods
of disposition by the sellers thereof set forth in such  Registration  Statement
as so amended or such Prospectus as so supplemented.

              (c) Notify the selling Series B Securityholders, the Initial Stock
holders,   the  Initiating  Holders,   the  Special  Counsel  and  the  Managing
Underwriters,  if any,  promptly,  and (if requested by any such person) confirm
such notice in writing,  (i) when a Prospectus,  any  Prospectus  supplement,  a
Registration Statement or a post-effective amendment to a Registration Statement
has been filed with the SEC,  and, with respect to a  Registration  Statement or
any post-effective amendment, when the same has

                                        8





become  effective,  (ii) of any request by the SEC or any other federal or state
governmental authority for amendments or supplements to a Registration Statement
or related Prospectus or for additional information, and of the contents of such
request,  (iii)  of the  issuance  by the  SEC or any  other  federal  or  state
governmental  authority  of any stop order  suspending  the  effectiveness  of a
Registration  Statement or the initiation or threatening of any  proceedings for
that  purpose,  (iv) of the  receipt  by the  Company of any  notification  with
respect to the suspension of the  qualification or exemption from  qualification
of any  of the  Registrable  Securities  for  sale  in any  jurisdiction  or the
initiation  or  threatening  of any  proceeding  for  such  purpose,  (v) of the
existence of any fact or  happening of any event which makes any  statement of a
material  fact in such  Registration  Statement  or  related  Prospectus  or any
document  incorporated or deemed to be incorporated  therein by reference untrue
or which would require the making of any changes in the  Registration  Statement
or Prospectus in order that, in the case of the Registration  Statement, it will
not  contain  any  untrue  statement  of a  material  fact or omit to state  any
material fact required to be stated  therein or necessary to make the statements
therein  not  misleading,  and that in the case of the  Prospectus,  it will not
contain any untrue  statement  of a material  fact or omit to state any material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary  to make the  statements  therein,  in the light of the  circumstances
under which they were made, not misleading,  provided that the Company shall not
be required  to  disclose  such fact or event if such fact or event has not been
publicly   disclosed,   and  (vi)  of  the   Company's   determination   that  a
post-effective amendment to a Registration Statement would be appropriate.

              (d) Use all  reasonable  efforts to obtain the  withdrawal  of any
order suspending the effectiveness of a Registration  Statement,  or the lifting
of any suspension of the qualification (or exemption from  qualification) of any
of the  Registrable  Securities  for sale in any  jurisdiction,  at the earliest
possible moment.

              (e)  If  reasonably  requested  by  an  Initial  Stockholder,  the
Initiating Holders, the Special Counsel, the Managing  Underwriters,  if any, or
the holders of a majority of the Registrable Securities being sold, (i) promptly
incorporate  in  a  Prospectus  supplement  or  post-effective  amendment  to  a
Registration  Statement  such  information  as  the  Initial  Stockholders,  the
Initiating Holders, the Special Counsel, the Managing  Underwriters,  if any, or
such holders, in connection with any offering of Registrable  Securities,  agree

required filings of such Prospectus supplement or such post-effective  amendment
as promptly as is practicable after the Company has received notification of the
matters to be  incorporated  in such  Prospectus  supplement  or  post-effective
amendment;  provided, that the Company shall not be required to take any actions
under this Section 2.2(e) that are not, in the reasonable opinion of counsel for
the Company, in compliance with or required by applicable law.

              (f) Furnish to each selling Series B  Securityholder,  the Special
Counsel,  the  Initial  Stockholders,  and each  Managing  Underwriter,  if any,
without  charge,  at least one conformed copy of the  Registration  Statement or

                                        9





amendment thereto,  including financial statements but excluding schedules,  all

Special Counsel, the Initial  Stockholders,  and each Managing  Underwriter,  if
any, in connection with any offering of Registrable Securities,  without charge,
as many copies of the Prospectus or  Prospectuses  relating to such  Registrable
Securities  (including  each  preliminary   prospectus)  and  any  amendment  or
supplement  thereto as such  persons  may  reasonably  request;  and the Company
hereby  consents to the use of such  Prospectus or each  amendment or supplement
thereto  by  each of the  selling  holders  of  Registrable  Securities  and the
underwriters,  if  any,  in  connection  with  any  offering  and  sale  of  the
Registrable Securities covered by such Prospectus or any amendment or supplement
thereto.

              (h) Prior to any public  offering of  Registrable  Securities,  to
register or qualify or cooperate with the selling Series B Securityholders,  the
Managing  Underwriters,  if any, and the Special  Counsel in connection with the
registration  or   qualification   (or  exemption  from  such   registration  or
qualification)  of such  Registrable  Securities  for offer  and sale  under the
securities  or Blue Sky laws of such  jurisdictions  within the United States as
any selling Series B Securityholder or Managing Underwriter  reasonably requests
in writing to the Company;  keep each such  registration  or  qualification  (or
exemption therefrom) effective during the period such Registration  Statement is
required to be kept effective and do any and all other acts or things  necessary
or advisable to enable the disposition in such  jurisdictions of the Registrable
Securities covered by the applicable Registration Statement;  provided, that the
Company  will not be  required to (i)  qualify  generally  to do business in any
jurisdiction  where it is not then so  qualified  or (ii) take any  action  that
would  subject it to general  service of process in suits or to  taxation in any
such jurisdiction where it is not then so subject.

              (i) Cause the  Registrable  Securities  covered by the  applicable
Registration  Statement  to  be  registered  with  or  approved  by  such  other
governmental  agencies or authorities within the United States, except as may be
required  solely  as a  consequence  of  the  nature  of  a  selling  holder  of
Registrable  Securities,  in  which  case  the  Company  will  cooperate  in all
reasonable  respects  with the  filing of such  Registration  Statement  and the
granting of such approvals,  as may be necessary to enable the selling holder or
holders  thereof  or the  Managing  Underwriters,  if  any,  to  consummate  the
disposition of such Registrable Securities.

              (j)  During  any  Selling  Period  (other  than  during a Deferral
Period),  immediately  upon the  existence of any fact or the  occurrence of any
event as a result of which a  Registration  Statement  shall  contain any untrue
statement of a material  fact or omit to state any material  fact required to be
stated therein or necessary to make the statements therein not misleading,  or a
Prospectus shall contain any untrue statement of a

                                       10





material fact or omit to state any material  fact required to be stated  therein
or necessary to make the statements  therein,  in the light of the circumstances
under  which  they  were  made,  not  misleading,  promptly  prepare  and file a
post-effective  amendment to each Registration  Statement or a supplement to the
related Prospectus or any document incorporated therein by reference or file any
other  required  document  (such as a Current  Report on Form 8-K) that would be
incorporated  by  reference  into  the   Registration   Statement  so  that  the
Registration Statement shall not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading,  and so that the Prospectus will not
contain any untrue  statement  of a material  fact or omit to state any material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary  to make the  statements  therein,  in the light of the  circumstances
under which they were made,  not  misleading,  as  thereafter  delivered  to the
purchasers of the Registrable Securities being sold thereunder, and, in the case
of a post-effective  amendment to a Registration  Statement,  use all reasonable
efforts to cause it to become effective as promptly as is practicable.

              (k) Enter  into  such  agreements  (including,  in the event of an
Underwritten Offering, an underwriting agreement in form, scope and substance as
is  customary  in  Underwritten  Offerings)  and take all such other  actions in
connection therewith (including, in the event of an underwritten offering, those
reasonably requested by the Managing  Underwriters,  if any, or the holders of a
majority  of the  Registrable  Securities  being  sold) in order to  expedite or
facilitate  the  disposition  of  such   Registrable   Securities  and  in  such
connection, whether or not an underwriting agreement is entered into, and if the
registration is an underwritten registration,  (i) make such representations and
warranties,  subject to the  Company's  ability to do so, to the holders of such
Registrable  Securities and the underwriters with respect to the business of the
Company  and  its  subsidiaries,  the  Registration  Statement,  Prospectus  and
documents incorporated by reference or deemed incorporated by reference, if any,
in each case, in form, substance and scope as are customarily made by issuers to
underwriters  in  underwritten  offerings  and  confirm  the  same  if and  when
requested;  (ii) obtain  opinions of counsel to the Company and updates  thereof
(which counsel and opinions (in form,  scope and substance)  shall be reasonably
satisfactory  to the  Managing  Underwriters,  if any,  Special  Counsel and the
holders of a majority of the  Registrable  Securities  being sold)  addressed to
each of the underwriters  covering the matters  customarily  covered in opinions
requested in underwritten  offerings and such other matters as may be reasonably
requested  by such  Special  Counsel and  Managing  Underwriters;  (iii)  obtain
"comfort"  letters and updates  thereof from the  independent  certified  public
accountants  of the Company  (and,  if  necessary,  any other  certified  public
accountants of any  subsidiary of the Company or any business  acquired or to be
acquired by the Company for which financial statements and financial data is, or
is required to be, included in the Registration Statement), addressed to each of
the Managing  Underwriters,  if any,  such  letters to be in customary  form and
covering  matters  of the type  customarily  covered  in  "comfort"  letters  in
connection  with  Underwritten  Offerings;  and (iv) deliver such  documents and
certificates as may be reasonably  requested by the holders of a majority of the
Registrable  Securities  being  sold,  the  Special  Counsel  and  the  Managing
Underwriters, if

                                       11





any, to evidence the continued validity of the representations and warranties of
the  Company  and its  subsidiaries  made  pursuant  to clause  (i) above and to
evidence compliance with any customary  conditions contained in the underwriting
agreement or other agreement entered into by the Company.

              (l) If requested in connection  with a disposition  of Registrable
Securities pursuant to a Registration  Statement,  make available for inspection
by a  representative  of the holders of Registrable  Securities  being sold, any
Managing Underwriter participating in any disposition of Registrable Securities,
if any,  and any  attorney or  accountant  retained by such  selling  holders or
underwriter,  financial and other  records,  pertinent  corporate  documents and
properties  of the  Company  and  its  subsidiaries,  and  cause  the  executive
officers,  directors and employees of the Company and its subsidiaries to supply
all  information  reasonably  requested  by any  such  representative,  Managing
Underwriter, attorney or accountant in connection with such disposition; subject
to reasonable  written assurances by each such person that such information will
only be used in connection with matters relating to such Registration Statement.

              (m) Comply with all  applicable  rules and  regulations of the SEC
and make generally  available to its  securityholders  earning statements (which
need  not  be  audited)  satisfying  the  provisions  of  Section  11(a)  of the
Securities Act and Rule 158 thereunder  (or any similar rule  promulgated  under
the Securities  Act) no later than 45 days after the end of any 12-month  period
(or 90 days  after the end of any  12-month  period  if such  period is a fiscal
year) (i)  commencing  at the end of any  fiscal  quarter  in which  Registrable
Securities  are  sold to  underwriters  in a firm  commitment  or  best  efforts
underwritten offering, and (ii) if not sold to underwriters in such an offering,
commencing  on  the  first  day of  the  first  fiscal  quarter  of the  Company
commencing  after  the  effective  date  of  a  Registration  Statement,   which
statements shall cover said 12- month periods.

              (n)  Cooperate  with  the  selling  Series  B  Securityholders  to
facilitate  the timely  preparation  and delivery of  certificates  representing
Registrable  Securities to be sold and not bearing any restrictive  legends; and
enable such Registrable Securities to be in such denominations and registered in
such names as the selling Series B Securityholders may request.

              (o) Use all  reasonable  efforts to provide a CUSIP number for the
Registrable Securities not later than the effective date of the registration.

              (p) Cause all Registrable  Securities  covered by the Registration
Statement to be listed on each securities  exchange or quotation system on which
the  Company's  Common  Stock  is  then  listed  no  later  than  the  date  the
Registration  Statement is declared effective and, in connection  therewith,  to
the extent  applicable,  to make such filings under the Exchange Act (e.g.,  the
filing  of a  Registration  Statement  on Form  8-A)  and to have  such  filings
declared effective thereunder.

                                       12





              (q) Cooperate  and assist in any filings  required to be made with
the National Association of Securities Dealers, Inc.

              (r)  Provide  and  cause to be  maintained  a  transfer  agent and
registrar for all Registrable  Securities covered by such registration statement
from and after a date not later  than the  effective  date of such  Registration
Statement.

              SECTION 2.3.  Holder's Obligations.

              (a) Each holder of Registrable  Securities  agrees,  by becoming a
transferee  of  any  Registrable  Securities,  that  no  holder  of  Registrable
Securities shall be entitled to sell any of such Registrable Securities pursuant
to a Registration Statement or to receive a Prospectus relating thereto,  unless
such holder has  furnished  the  Company  with the notice  required  pursuant to
Section  2.1(d) hereof  (including  the  information  required to accompany such
notice)  and,  promptly  after the  Company's  request,  such other  information
regarding such holder and the distribution of such Registrable Securities as the
Company may from time to time reasonably  request.  The Company may exclude from
such registration the Registrable  Securities of any holder who does not furnish
such  information  provided  above  for so long as  such  information  is not so
furnished.  Each holder of Registrable  Securities as to which any  Registration
Statement  is being  effected  agrees  promptly  to furnish to the  Company  all
information required to be disclosed in order to make the information previously
furnished  to the  Company  by  such  holder  not  misleading.  Any  sale of any
Registrable  Securities  by any holder  shall  constitute a  representation  and
warranty  by such holder  that the  information  relating to such holder and its
plan of distribution is as set forth in the Prospectus  delivered by such holder
in connection  with such  disposition,  that such  Prospectus does not as of the
time of such sale contain any untrue  statement of a material  fact  relating to
such holder or its plan of distribution  and that such Prospectus does not as of
the time of such sale omit to state any material fact relating to such holder or
its plan of distribution necessary to make the statements in such Prospectus, in
light of the circumstances under which they were made, not misleading.

              (b) The  Company  agrees  (x) that if any  holder  of  Registrable
Securities   shall  send  a  written  notice  to  the  Company  of  an  intended
distribution of Registrable  Securities under the Shelf Registration pursuant to
Section  2.1(d),  the Company  shall not to sell,  make any short sale of, loan,
grant any option for the purchase of, effect any public sale or  distribution of
or otherwise dispose of its equity securities or securities  convertible into or
exchangeable or exercisable  for any of such  securities  during the period from
first day of the applicable  Selling Period until the date that is 90 days after
the date when such  holder  shall  have made such  distribution  of  Registrable
Securities under the Shelf Registration,  as the holder or managing  underwriter
(in the case of an  Underwritten  Offering)  shall advise the Company  (provided
that if the holder or managing  underwriter  shall fail to advise the Company of
any such date prior to the end of the  applicable  Selling  Period,  such period
shall end on the last day of the applicable Selling Period),  except (i) as part
of such registration, (ii) pursuant to

                                       13





registrations  on Form S-4 or S-8 or any  successor or similar  forms thereto or
(iii) as otherwise  permitted by the managing  underwriter  of such offering (if
any), and (y) to use all  reasonable  efforts to cause each holder of its equity
securities or any securities convertible into or exchangeable or exercisable for
any of such  securities,  in each case  purchased  from the  Company at any time
after the date of this Agreement  (other than in a public offering) to agree not
to sell,  make any short sale of,  loan,  grant any option for the  purchase of,
effect  any  public  sale  or  distribution  of or  otherwise  dispose  of  such
securities during such period except as part of such underwritten  registration;
provided that no holder of Registrable  Securities  included in any underwritten
registration shall be required to make any  representations or warranties to the
Company or the underwriters other than  representations and warranties regarding
such holder and such holder's intended method of distribution.

              SECTION 2.4. Registration Expenses. All fees and expenses incident
to the Company's performance of or compliance with this Agreement shall be borne
by the  Company  whether  or  not  any of  the  Registration  Statements  become
effective.  Such fees and expenses shall include,  without  limitation,  (i) all
registration and filing fees (including,  without limitation,  fees and expenses
(x) with respect to filings required to be made with the National Association of
Securities  Dealers,  Inc. and (y) of compliance with federal securities or Blue
Sky laws  (including,  without  limitation,  fees and  disbursements  of Special
Counsel in connection with Blue Sky qualifications of the Registrable Securities
laws of such jurisdictions as the Managing Underwriters, if any, or holders of a
majority of the Registrable Securities being sold may designate),  (ii) printing
expenses (including,  without limitation,  expenses of printing certificates for
Registrable  Securities in a form eligible for deposit with The Depositary Trust
Company  and  of  printing  prospectuses  if the  printing  of  prospectuses  is
requested by the Special Counsel or the holders of a majority of the Registrable
Securities included in any Registration Statement),  (iii) messenger,  telephone
and delivery expenses, (iv) reasonable fees and disbursements of counsel for the
Company and the Special  Counsel in connection with the  Registration,  (v) fees
and disbursements of all independent certified public accountants referred to in
Section  2.2(k)(iii)  hereof  (including  the expenses of any special  audit and
"comfort"  letters  required  by or  incident  to  such  performance)  and  (vi)
Securities  Act  liability  insurance  obtained  by  the  Company  in  its  sole
discretion. In addition, the Company shall pay its internal expenses (including,
without  limitation,  all salaries  and  expenses of its officers and  employees
performing  legal or accounting  duties),  the expense of any annual audit,  the
fees and expenses  incurred in connection  with the listing of the securities to
be registered on any securities  exchange on which similar  securities issued by
the Company are then listed and the fees and  expenses of any person,  including
special experts, retained by the Company. Notwithstanding the provisions of this
Section 2.4, each seller of Registrable  Securities  shall pay all  registration
expenses to the extent the Company is  prohibited  by  applicable  Blue Sky laws
from paying for or on behalf of such seller of Registrable Securities.

              SECTION 2.5.  Indemnification.


                                       14





              (a) The Company  agrees to indemnify and hold harmless each holder
of  Registrable  Securities  whose  Registrable  Securities  are  covered by any
registration  statement,  its directors  and officers and each other Person,  if
any, who controls such holder within the meaning of the Securities Act,  against
any losses, claims, damages or liabilities,  joint or several, to which any such
indemnified  party may become  subject  under the  Securities  Act or otherwise,
insofar  as  such  losses,   claims,  damages  or  liabilities  (or  actions  or
proceedings,  whether commenced or threatened,  in respect thereof) arise out of
or are based  upon any  untrue  statement  or alleged  untrue  statement  of any
material  fact  contained  in  any  registration   statement  under  which  such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus  contained  therein,  or any amendment or
supplement  thereto,  or any  omission or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading,  and the Company will reimburse  each such  indemnified
party  for any  legal  or any  other  expenses  reasonably  incurred  by them in
connection  with  investigating  or defending any such loss,  claim,  liability,
action or proceeding;  provided that the Company shall not be liable in any such
case to the extent that any such loss,  claim,  damage,  liability (or action or
proceeding  in respect  thereof)  or  expense  arises out of or is based upon an
untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in such  registration  statement,  any such preliminary  prospectus,  final
prospectus, summary prospectus,  amendment or supplement in reliance upon and in
conformity with written information  furnished to the Company by or on behalf of
such holder specifically for use in the preparation  thereof.  In addition,  the
Company shall  indemnify any underwriter of such offering and each other Person,
if any, who controls any such  underwriter  within the meaning of the Securities
Act in substantially the same manner and to substantially the same extent as the
indemnity herein provided to each Indemnified Party. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
such holder or any such director, officer, underwriter or controlling person and
shall survive the transfer of such securities by such holder.

              (b) Each prospective  seller of Registrable  Securities  hereunder
shall  indemnify and hold harmless (in the same manner and to the same extent as
set forth in subdivision (a) of this Section 2.5) the Company,  each director of
the  Company,  each  officer of the Company and each other  person,  if any, who
controls the Company within the meaning of the  Securities  Act, with respect to
any statement or alleged  statement in or omission or alleged omission from such
registration statement, any preliminary prospectus,  final prospectus or summary
prospectus  contained therein,  or any amendment or supplement  thereof, if such
statement  or alleged  statement  or  omission or alleged  omission  was made in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by or on behalf of such seller  specifically  for use in the preparation
of  such  registration  statement,  preliminary  prospectus,  final  prospectus,
summary prospectus,  amendment or supplement. Any such indemnity shall remain in
full force and effect,  regardless of any investigation  made by or on behalf of
the  Company  or any such  director,  officer  or  controlling  person and shall
survive the transfer of such  securities by such seller.  The amount  payable by
any prospective seller of

                                       15





Registrable  Securities  with respect to the  indemnification  set forth in this
subsection (b) in connection  with any offering of Registrable  Securities  will
not exceed the amount of the gain realized by such  prospective  seller pursuant
to such offering.

              (c) Promptly  after receipt by an  indemnified  party of notice of
the  commencement  of any action or proceeding  involving a claim referred to in
the preceding  subdivisions of this Section 2.5, such indemnified party will, if
a claim in respect  thereof is to be made against an  indemnifying  party,  give
written notice to the latter of the  commencement of such action;  provided that
the failure of any indemnified party to give notice as provided herein shall not
relieve  the  indemnifying   party  of  its  obligations   under  the  preceding
subdivisions  of this  Section 2.5,  except to the extent that the  indemnifying
party is actually  prejudiced  by such failure to give notice.  In case any such
action is  brought  against an  indemnified  party,  unless in such  indemnified
party's reasonable  judgment a conflict of interest between such indemnified and
indemnifying  parties may exist in respect of such claim, the indemnifying party
shall be entitled to participate in and to assume the defense  thereof,  jointly
with any other  indemnifying  party similarly  notified,  to the extent that the
indemnifying  party may  wish,  with  counsel  reasonably  satisfactory  to such
indemnified  party,  and  after  notice  from  the  indemnifying  party  to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense  thereof.  No  indemnifying  party  shall,  without  the  consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
of any such action which does not include as an  unconditional  term thereof the
giving by the claimant or plaintiff to such indemnified  party of a release from
all liability in respect to such claim or litigation. No indemnified party shall
consent to entry of any judgment or enter into any settlement of any such action
the  defense of which has been  assumed by an  indemnifying  party  without  the
consent of such indemnifying party.

              (d)  If  the   indemnification   provided  for  in  the  preceding
subdivisions  of this  Section 2.5 is  unavailable  to an  indemnified  party in
respect of any expense,  loss, claim,  damage or liability  referred to therein,
then each indemnifying  party, in lieu of indemnifying  such indemnified  party,
shall  contribute to the amount paid or payable by such  indemnified  party as a
result of such expense,  loss, claim, damage or liability (i) in such proportion
as is  appropriate to reflect the relative  benefits  received by the Company on
the one hand and the  holder  or  underwriter,  as the case may be, on the other
from the  distribution of the  Registrable  Securities or (ii) if the allocation
provided  by clause  (i)  above is not  permitted  by  applicable  law,  in such
proportion as is appropriate to reflect not only the relative  benefits referred
to in clause  (i) above but also the  relative  fault of the  Company on the one
hand and of the  holder  or  underwriter,  as the case may be,  on the  other in
connection  with the  statements  or omissions  which  resulted in such expense,
loss,   damage  or  liability,   as  well  as  any  other   relevant   equitable
considerations.  The relative  benefits  received by the Company on the one hand
and the holder or  underwriter,  as the case may be, on the other in  connection
with the distribution of the Registrable Securities shall be deemed to be in the
same proportion as (i) the product of the

                                       16





Liquidation  Preference  (as  defined  in  Exhibit  1.7 of the Stock  Agreement)
multiplied  by the number of shares of Series B  Preferred  Stock into which the
Conversion Shares subject to the relevant distribution were converted,  bears to
(ii) the gain realized by the selling holder or the  underwriting  discounts and
commissions received by the underwriter,  as the case may be. The relative fault
of the Company on the one hand and of the holder or underwriter, as the case may
be, on the other shall be  determined  by  reference  to,  among  other  things,
whether the untrue or alleged untrue statement of a material fact or omission to
state a material  fact relates to  information  supplied by the Company,  by the
holder or by the underwriter and parties' relative intent, knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission;
provided  that the  foregoing  contribution  agreement  shall  not  inure to the
benefit of any indemnified party if indemnification would be unavailable to such
indemnified  party by reason of the proviso  contained in the first  sentence of
subdivision (a) of this Section 2.5, and in no event shall the obligation of any
indemnifying  party to contribute  under this  subdivision (d) exceed the amount
that  such  indemnifying  party  would  have  been  obligated  to  pay by way of
indemnification  if the  indemnification  provided for under subdivisions (a) or
(b) of this Section 2.5 had been available under the circumstances.

              The Company and the holders of Registrable  Securities  agree that
it would not be just and equitable if contribution  pursuant to this subdivision
(d)  were  determined  by pro  rata  allocation  (even  if the  holders  and any
underwriters were treated as one entity for such purpose) or by any other method
of  allocation  that  does  not take  account  of the  equitable  considerations
referred to in the immediately  preceding  paragraph and subdivision (c) of this
Section 2.5. The amount paid or payable by an  indemnified  party as a result of
the losses,  claims,  damages  and  liabilities  referred to in the  immediately
preceding  paragraph shall be deemed to include,  subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.

              Notwithstanding  the provisions of this subdivision (d), no holder
of  Registrable  Securities or  underwriter  shall be required to contribute any
amount in excess of the amount by which (i) in the case of any such holder,  the
gain realized by such holder from the sale of Registrable  Securities or (ii) in
the case of an underwriter,  the total price at which the Registrable Securities
purchased  by it and  distributed  to the  public  were  offered  to the  public
exceeds,  in any such  case,  the  amount of any  damages  that  such  holder or
underwriter  has  otherwise  been  required  to pay by reason of such  untrue or
alleged   untrue   statement  or  omission.   No  Person  guilty  of  fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent misrepresentation.

                                       17






              SECTION 2.6. Rule 144; Rule 144A; Form S-3.

              (a) The Company  will file all reports  required to be filed by it
under the  Securities  Act and the  Exchange  Act and the rules and  regulations
adopted by the  Commission  thereunder  and will take such further action as any

                              MANAGEMENT AGREEMENT

         THIS MANAGEMENT AGREEMENT (the "Agreement") is made and entered into as
of January 17, 1997 by and among Perini Corporation, a Massachusetts corporation
("Perini"),  Tutor-Saliba Corporation, a California corporation ("Tutor-Saliba")
and Ronald N. Tutor ("Tutor"), an individual and President of Tutor-Saliba.

         WHEREAS,  Perini has had some difficulty  meeting its cash requirements
for the past year due to, inter alia, its high level of capital-intensive  civil
construction work and the cash support required by its real estate assets;

         WHEREAS,  Perini's  financial  condition  has  impeded  its  ability to
perform on existing projects and to bid on new projects;

         WHEREAS,  during the  course of 1996,  Perini  engaged in an  extensive
search  for new  capital  to  support  its  cash  needs  and to  provide  it the
opportunity to improve operations and improve its competitiveness in the general
contracting and construction industry;

         WHEREAS,  as a result of its search for capital,  Perini entered into a
Stock  Purchase and Sale Agreement  dated July 24, 1996 by and among Perini,  PB
Capital Partners,  L.P., a Delaware limited partnership ("PB Capital Partners"),
and  Richard  C. Blum &  Associates,  L.P.,  a  California  limited  partnership
("RCBA") (as amended through the date hereof,  the "Stock Purchase  Agreement"),
pursuant  to  which  it is  contemplated  that  Perini  will  issue  convertible
preferred  stock to PB Capital  Partners in  exchange  for an  investment  by PB
Capital Partners of $30,030,000 (the "Investment");

         WHEREAS, Tutor-Saliba is a limited partner of PB Capital Partners;

         WHEREAS,   Tutor-Saliba   directly  owns  approximately  7.24%  of  the
outstanding  common  stock,  par value $1.00 per share (the  "Common  Stock") of
Perini;

         WHEREAS,  Tutor-Saliba  has from time to time  engaged in  construction
joint ventures with Perini under the name Tutor-Saliba/Perini;

         WHEREAS,  considering the existing and potential relationships,  direct
and indirect,  between Tutor-Saliba and Perini, as well as Tutor's expertise and
achievements  in the  construction  industry,  the  parties  hereto  desire,  in
connection with and contingent upon the Investment,  that  Tutor-Saliba  provide
the  services of Tutor to Perini,  for the  purpose of  providing  direction  to
Perini  with  respect to its  ongoing  and future  construction  operations  and
improving  Perini's  operating  efficiency and thus its ability to  successfully
compete for new projects and in new areas;

         NOW  THEREFORE,  in  consideration  of the  premises  and of the mutual
covenants herein contained, the parties hereby agree as follows:








         1.  Effectiveness.  Unless  sooner  terminated  pursuant  to  Section 6
hereof,  this Agreement shall become effective on the date of the closing of the
Investment (the "Effective Date").

         2.       Management.

                  (a)  Tutor-Saliba  and Tutor each  hereby  agree to provide to
Perini the management services of Tutor, to assist Perini from time to time (but
for no more  than  ten (10)  days in any  calendar  month,  unless  the  parties
otherwise  agree in  writing)  as  described  in Section  2(b)  hereof or as the
parties hereto may otherwise agree.

                  (b) Tutor  shall  initially  serve as acting  Chief  Operating
Officer of Perini,  and will provide  direction with respect to Perini's ongoing
and future construction operations, with the goal of achieving greater operating
efficiencies,  reducing  Perini's need for working  capital,  reducing  Perini's
exposure to risk by negotiating and bidding on  construction  projects that will
yield higher profit  margins than current  projects,  negotiating  with Perini's
lenders,  bonding companies and insurers,  and generally improving Perini's cash
flow  situation  and  competitive   position  in  the  general  contracting  and
construction industry.

                  (c)  Perini  hereby  agrees  to take all  action  which may be
required to: (i) appoint Tutor acting Chief  Operating  Officer of Perini;  (ii)
provide Tutor with the use of an office at Perini's principal  executive offices
and administrative and other support services as may be reasonably  necessary in
connection with the  performance of Tutor's  services under Section 2(b) hereof;
(iii)  make  available  to  Tutor  the  services  of such of its  employees  and
consultants  as may be reasonably  necessary to the  performance of the services
described  in Section 2(b) above;  and (iv) issue the Option (as defined  below)
and otherwise pay the management fee pursuant to Section 3 hereof.

         3.  Compensation.  In return for the  provision  of  Tutor's  services,
Perini shall pay a management fee as follows:

                  (a) On the  Effective  Date,  Perini  shall  issue  to  Tutor,
pursuant to  Perini's  1982 Stock  Option and  Long-Term  Performance  Incentive
Compensation  Plan,  as amended  (the  "Plan")  (or,  in the event  options  are
unavailable  for issuance under such plan,  with similar terms and conditions as
under the Plan),  an option (the  "Option")  exercisable  for 150,000  shares of
Common Stock, with an exercise price per share equal to the closing price of the
Common Stock on the American  Stock  Exchange on the day prior to the  Effective
Date. The Option will first become  exercisable forty months after the Effective
Date.

                  (b) Beginning on the Effective Date, Perini shall pay a fee to
Tutor-Saliba  at the rate of $150,000 per year, such amount to be paid in twelve
equal  monthly  installments  in  arrears on the 15th of each  month,  or as the
parties hereto shall otherwise agree in writing.


                                        2





         4.       Limitation of Liability.

                  (a)  Neither  Tutor  nor  Tutor-Saliba  makes any  express  or
implied representation,  warranty or guaranty to Perini relating to the services
to be performed by Tutor pursuant to this Agreement or the quality or results of
such services.

                  (b) Neither Tutor nor  Tutor-Saliba  shall be liable to Perini
or to any of its subsidiaries or affiliates or to any third party for failure to
perform  the  services  to be  performed  by  either  of them  pursuant  to this
Agreement for any expense, claim, loss or damage, including, without limitation,
indirect,  special,  consequential or exemplary damages,  suffered other than by
reason of such  party's  intentional  failure  to  perform  the  services  to be
performed by such party pursuant to this Agreement, or by reason of action taken
or omitted to be taken by such party  which was in bad faith and in a manner not
reasonably believed by such party to be in the best interests of Perini.

         5.   Indemnification.   Perini  shall  indemnify  and  hold  Tutor  and
Tutor-Saliba  harmless against all loss, cost, liability and expense arising out
of the  performance of this Agreement by Tutor and  Tutor-Saliba,  upon the same
terms and  conditions  as those  provided to officers and directors of Perini by
Section 9 of the By-laws of Perini. A true, complete and correct copy of Section
9 of the By-laws of Perini is attached hereto as Exhibit A.

         6.  Termination.   Unless  earlier  terminated  by  the  parties,  this
Agreement  shall  terminate upon the earliest to occur of (i) December 31, 1998,
(ii)  Tutor's  inability to perform the services  contemplated  hereby,  whether
because of death,  disability or otherwise,  (iii) written notice from Perini to
Tutor after, in the  determination  of a majority of the Executive  Committee of
the Board of  Directors of Perini,  Tutor has failed to perform his  obligations
under this  Agreement,  and (iv) the  reasonable  determination  by the Board of
Directors or Executive Committee of Perini, and written notice thereof to Tutor,
that it would be  inadvisable  for Tutor to  continue  performing  the  services
contemplated by this Agreement.

         7. Governing Law. This Agreement  shall be construed under and governed
by the internal laws of the Commonwealth of Massachusetts  without regard to its
conflict of laws provisions.

                                    EXHIBIT A

SECTION 9.        Indemnification of Directors and Officers

         9.1  General.  Subject  to  the  provision  of  this  Section  and  any
limitations  imposed by law, the  corporation  shall indemnify its directors and
officers against all expenses incurred by them in connection with any proceeding
in which they are involved by reason of their serving in such capacities  except
that (i) no  indemnification  shall be provided for any director or officer with
respect  to any matter as to which he shall  have been  adjudicated  not to have
acted in good faith and in the reasonable belief that his action was in the best
interests of the corporation,  or with respect to a criminal matter, that he had
reasonable  cause  to  believe  that  his  conduct  was  unlawful,  and  (ii) no
indemnification  shall be provided for any director or officer with respect to a
proceeding by or in the right of the  corporation  in which he is adjudicated to
be liable to the corporation. Such indemnification may be provided to an officer
or director  in  connection  with a  proceeding  in which it is alleged  that he
received an improper  personal benefit by reason of his position,  regardless of
whether  the claim  involves  his  services  in such  capacity,  subject  to the
foregoing  limitation,  unless it shall have been  determined  that an  improper
personal benefit was received by the director or officer.  Except as provided in
Section 9.2,  indemnification  under this Section 9 shall be  authorized in each
case as determined by the board of directors, which may act notwithstanding that
one or more of these  members  are  parties to the  proceeding  in  question  or
otherwise have an interest in such indemnification.

         9.2 Mandatory Indemnification.  Notwithstanding any contrary provisions
of this  Section,  if a director or officer of the  corporation  has been wholly
successful  on the merits in defense of any  proceeding in which he was involved
by  reason  of his  position  or as a result  of his  serving  in such  capacity
(including  the  termination of  investigative  or other  proceedings  without a
finding  of  fault  on the  part  of the  director  of  officer),  he  shall  be
indemnified  by  the  corporation  against  all  expenses  incurred  by  him  in
connection therewith.

         9.3      Definitions.  For purposes of this Section 9:

                  (a) A "director" or "officer"  means any person  serving in an
office filled by  appointment  or election by the directors or the  stockholders
and also  includes (i) a director or officer of the  corporation  serving at the
request of the corporation as a director, officer, employee, trustee, partner or
other agent of another  organization,  (ii) any person who formerly  served as a
director or officer,  and (iii) the heirs or  personal  representatives  of such
persons;

                  (b) "Expenses" means all expenses  (including  attorneys' fees
and disbursements)  actually and reasonably  incurred in defense of a proceeding
or in successfully  seeking  indemnification  under Section 9.2 hereof,  and any
judgments, awards, fines, penalties and reasonable amounts paid in settlement of
a proceeding; and


                                        7





                  (c) A "proceeding" means any threatened,  pending or completed
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative, and any claim which could be the subject of a proceeding.

         9.4 Advances. Except as limited by law, expenses incurred by a director
or officer in  defending  any  proceeding  in which he is  involved by reason of
serving in such  capacities  may be paid by the  corporation in advance of final
disposition of the proceeding  upon receipt of his written  undertaking to repay
such  amount  if it is  ultimately  determined  that  he is not  eligible  to be
indemnified, which undertaking shall be an unlimited general obligation but need
not be secured and may be accepted  without  regard to the financial  ability of
such persons to make repayment;  provided, that no such advance payment shall be
made  if it is  determined  by  the  board  of  directors  on the  basis  of the
circumstances  known at the  time  (without  further  investigation)  that  said
director or officer will  ultimately be ineligible to be indemnified  under this
Section 9.

         9.5 Settlement  Proceedings.  If a proceeding is compromised or settled
in a manner which imposes a liability or obligation  upon a director or officer,
(i) no indemnification  shall be provided to him with respect to a proceeding by
or in the right of the corporation  unless the board of directors  determines in
its discretion that indemnification is appropriate under the circumstances,  and
(ii) no indemnification  shall be provided to him with respect to any other type
of proceeding  if it is determined by the board of directors  that said director
or  officer  is  ineligible  to  be  indemnified   under  this  Section  9.  The
determination  by the board of directors in each case shall be made on the basis
of the circumstances know to it at that time without further investigation.

         9.6  Insurance.  The  corporation  shall  have  power to  purchase  and
maintain insurance on behalf of any director,  officer, employee or agent of the
corporation  against any  liability or cost incurred by him in any such capacity
or arising out of his status as such,  whether or not the corporation would have
the power to indemnify him against such liability or cost.

         9.7 Employee  Benefit Plans. If the corporation or any of its directors
or officers  sponsors,  undertakes or incurs any  responsibility  as a fiduciary
with respect to an employee benefit plan, then, for purposes of  indemnification
of such person under this Section (i) a "director" or "officer"  shall be deemed
to include any director or officer of the  corporation who serves at its request
in any capacity  with respect to said plan,  (ii) such director or officer shall
be deemed not to have  failed to have acted in good faith and in the  reasonable
belief that his action has in the best interests of the  corporation if he acted
in good  faith and in the  reasonable  belief  that his  action  was in the best
interest of the participants or beneficiaries of said plan, and (iii) "expenses"
shall be deemed to include any taxes or penalties  assessed on such  director or
officer with respect to said plan under applicable law.

         9.8 Other  Provisions.  The  provisions  of this Section 9 shall not be
construed to limit the power of the  corporation  to  indemnify  its officers or
directors to the full extent  permitted by law and enter specific  agreements or
arrangements for this purpose. In addition,  the corporation shall have power to
indemnify any of its agents or employees who

                                        8




are not directors or officers on any terms consistent with law which it deems to
be appropriate.

         9.9  Amendment.  The  provisions  of this  Section 9 may be  amended or
repealed  by the  stockholders;  however,  no such  amendment  or  repeal  which
adversely  affects the rights of a director of officer under this Section 9 with
respect to his acts or omissions at any time prior to such  amendment or repeal,
shall apply to him without consent.
