                       PERINI CORPORATION AND SUBSIDIARIES

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS


(1)     Significant Accounting Policies

        The  significant  accounting  policies  followed  by the Company and its
        subsidiaries in preparing its consolidated  financial statements are set
        forth in Note (1) to such financial statements included in Form 10-K for
        the year ended  December 31, 1995.  The Company has made no  significant
        change in these policies during 1996.

(2)     Income (Loss) From Operations

        The three and nine month  periods  ended  September  30, 1995  include a
        charge,  which  aggregated  $25.6  million,  to provide  for a liability
        related to  previously  disclosed  litigation  discussed  under "Item 1.
        Legal  Proceedings" in the Company's Form 10-Q for the quarterly  period
        ended September 30, 1995, and downward  revisions in estimated  probable
        recoveries on certain outstanding contract claims.

(3)     Provision For Income Taxes

        The lower than  normal tax rate in 1996 is due to the  realization  of a
        portion of the Federal tax benefit  resulting  from the  operating  loss
        recorded in 1995. Because of certain accounting limitations, the Company
        was not able to  recognize a portion of the tax  benefit  related to the
        operating loss experienced in fiscal 1995.

(4)     Per Share Data

        Computations  of  earnings  per common  share  amounts  are based on the
        weighted  average  number of the  Company's  common  shares  outstanding
        during the periods  presented.  Earnings  per common  share  reflect the
        effect of  preferred  dividends  accrued  during  both the 1996 and 1995
        three  and nine  month  periods  ended  September  30, of  $531,000  and
        $1,593,000, respectively. Common stock equivalents related to additional
        shares of common stock  issuable upon exercise of stock options have not
        been included since their effect would be  antidilutive.  Per share data
        on a  fully  diluted  basis  is not  presented  because  the  effect  of
        conversion  of  the  Company's   depositary   convertible   exchangeable
        preferred shares into common stock is also antidilutive.

(5)     Cash Dividends

        There were no cash dividends on common stock declared or paid during the
        periods  presented in the consolidated  condensed  financial  statements
        presented  herein.  As  previously  disclosed in the 1995 Form 10-K,  in
        conjunction with the covenants of the Company's Amended Revolving Credit
        Agreement,  the Company is required to suspend the payment of  quarterly
        dividends on its preferred  stock until the Bridge Loan commitment is no
        longer  outstanding,  if a default exists under the terms of the Amended
        Revolving Credit Agreement,  or if the ratio of long-term debt to equity
        exceeds 50%.  Therefore,  the dividends on preferred stock that normally
        would have been  declared  during  December of 1995 and March,  June and
        September of 1996,  and payable on March 15, June 15,  September 15, and
        December 15, 1996,  respectively,  have not been declared (although they
        have been fully accrued due to the "cumulative" feature of the preferred
        stock).

(6)     Capitalization

        In addition to its $114.5 million revolving credit agreement,  effective
        February 26, 1996, the Company entered into a Bridge Loan Agreement with
        its revolver  banks to borrow up to an  additional  $15 million  through
        July 31, 1996 at an interest  rate of prime plus 2%.  Subsequently,  the
        Bridge Loan Agreement has been increased to provide  another $10 million
        of borrowing  capacity at an interest rate of prime plus 4% and extended
        through  the  earlier of the  closing of the below  mentioned  preferred
        stock  transaction or January 31, 1997. The Revolving  Credit  Agreement
        has been  renegotiated  and will total $129.5 million  subsequent to the
        closing of the preferred stock transaction.  Additionally, in July 1996,
        the Company  announced  that it had entered  into an  agreement  with an
        investor  group  led by  Richard  C.  Blum &  Associates,  L.  P. of San
        Francisco, California, for a $30 million investment in the form of a new
        issuance of 150,150 shares of redeemable  cumulative  convertible junior
        preferred stock in the Company. The preferred stock will

                                        6

(6)     Capitalization (continued)

        be  convertible  into  shares  of  common  stock  of  the  Company  at a
        conversion  price of  approximately  $9.68 per share.  The  issuance and
        listing of any such  common  stock on the  American  Stock  Exchange  is
        subject to  shareholder  ratification  of the  transaction  at a Special
        Meeting of Stockholders  of the Company,  the date of which has not been
        set.  The  preferred  shares  will  carry  voting  rights   representing
        approximately 37% of the outstanding common shares and will also entitle
        the investor group to the  appointment of three members to the Company's
        Board of Directors.  Subject to the  ratification  of the transaction by
        the  stockholders,   the  Company  expects  to  be  able  to  close  the
        transaction by year end.

(7)     Management's Opinion

        The unaudited  consolidated  condensed  financial  statements  presented
        herein have been prepared in accordance  with the  instructions  to Form
        10-Q and do not  include  all of the  information  and note  disclosures
        required by generally accepted accounting  principles.  These statements
        should be read in  conjunction  with the financial  statements and notes
        thereto  included in the Company's Form 10-K for the year ended December
        31,  1995.  In the opinion of  management,  the  accompanying  unaudited
        condensed financial statements include all adjustments,  consisting only
        of  normal  recurring  adjustments,  necessary  to  present  fairly  the
        Company's  financial  position as of September 30, 1996 and December 31,
        1995 and results of operations and cash flows for the nine month periods
        ended  September 30, 1996 and 1995.  The results of  operations  for the
        nine month period ended  September 30, 1996 may not be indicative of the
        results  that may be  expected  for the year  ending  December  31, 1996
        because the Company's  results  generally consist of a limited number of
        large transactions in both construction and real estate. Therefore, such
        results  can  vary  depending  on the  timing  of  transactions  and the
        profitability of projects being reported.

       MANAGEMENT'S DISCUSSION AND ANALYSIS OF THE CONSOLIDATED CONDENSED
                              FINANCIAL STATEMENTS

RESULTS OF OPERATIONS

     Comparison of the Third Quarter of 1996 with the Third Quarter of 1995
     ----------------------------------------------------------------------

Revenues  increased  $107.7  million  (or 46.2%),  from $233  million in 1995 to
$340.7  million in 1996.  This  increase  resulted from  increased  construction
revenues  of $96  million  (or  42.9%),  from  $223.7  million in 1995 to $319.7
million  in 1996,  due  primarily  to an  increase  in  revenues  from  building
operations  of $70  million (or  45.2%),  from $154.9  million in 1995 to $224.9
million in 1996.  This  increase was due primarily to the timing in the start-up
of certain fast track hotel/casino projects in the western United States as well
as several  prison/detention and medical facilities projects in the northeastern
United  States.  Revenues  from heavy  operations  increased  by $26 million (or
37.8%), from $68.8 million in 1995 to $94.8 million in 1996 due primarily to the
favorable  impact of several  large  infrastructure  projects  under way in late
1995,  primarily in the metropolitan New York,  Boston and Los Angeles areas. In
addition,  revenues from real estate operations increased by $11.7 million, from
$9.3  million in 1995 to $21  million  in 1996 due  primarily  to the  Company's
acquisition  during  1996 of an  increased  ownership  position in The Resort at
Squaw Creek joint venture in California.

Along  with  the  increase  in  revenues,   the  total  gross  profit  increased
substantially,  from a loss of $23 million in 1995 to a profit of $13 million in
1996, due to an overall increase in gross profit from construction operations of
$36.4 million, from a loss of $23.2 million in 1995 to a profit of $13.2 million
in 1996. The gross loss from construction operations recognized in 1995 included
a pretax charge,  which  aggregated  $25.6  million,  to provide for a liability
related to  litigation  involving  a joint  venture in which the  Company  was a
minority  partner,  and the  Washington  Metropolitan  Transit  Authority on two
subway  construction  projects in Washington,  D.C.,  and downward  revisions in
estimated  probable  recoveries  on  certain  outstanding  contract  claims.  In
addition,  the 1995 gross profit was adversely  impacted by an overall reduction
in the profit level on a tunnel  project in the Midwest.  The pretax  charges in
1995, coupled with the increased construction revenues in 1996 referred to above
and the favorable profit impact in 1996 of several large infrastructure projects
underway in late 1995,  primarily in the metropolitan  New York,  Boston and Los
Angeles  areas,  resulted  in the  substantial  increase  in gross  profit  from
construction operations in 1996. Real estate operations experienced a gross loss
of $.2 million in 1996  compared to a gross profit of $.2 million in 1995 due to
a lower volume of condominium  sales in Georgia and land sales in Arizona during
1996.

The decrease in general, administrative and selling expenses of $1.0 million (or
11.6%),  from $9 million in 1995 to $8 million in 1996,  resulted primarily from
continued  emphasis on reducing overall Company overhead expenses in conjunction
with the Company's  re-engineering efforts commenced in prior years, the sale in
June of 1996 of Pioneer Construction, a former subsidiary of the Company located
in West Virginia which performed reclamation projects on abandoned mine lands in
that  state,   and  the   continuation  of  the  down-sizing  of  the  Company's
environmental remediation construction operation.

Interest expense increased by $.4 million (or 18.9%),  from $2.2 million in 1995
to $2.6 million in 1996,  due to a higher  average  level of  borrowings  during
1996.

The lower than normal tax rate in 1996 is due to the realization of a portion of
the Federal tax benefit  resulting  from the  operating  loss  recorded in 1995.
Because of certain accounting limitations, the Company was not able to recognize
a portion of the tax benefit related to the operating loss experienced in fiscal
1995.

   Comparison of the Nine Months Ended September 30, 1996 with the Nine Months
                            Ended September 30, 1995
                            ------------------------

Revenues  increased  $124.2  million  (or 15.5%),  from $803  million in 1995 to
$927.2  million in 1996.  This  increase  resulted from  increased  construction
revenues of $114.7  million (or  14.9%),  from $770.7  million in 1995 to $885.4
million  in  1996,   due  primarily  to  an  increase  in  revenues  from  heavy
construction operations of $75.1 million (or 36.9%), from $203.7 million in 1995
to $278.8 million in 1996, as well as an

                                        8

<PAGE>



increase in revenues from building construction  operations of $39.6 million (or
7.0%),  from $567  million  in 1995 to $606.6  million  in 1996.  These  revenue
fluctuations reflect the timing in the start-up of new construction projects, in
particular  several  fast  track  hotel/casino   projects  in  the  western  and
midwestern  United  States,  several  prison/detention  and  medical  facilities
projects in the northeastern United States, and several long-term infrastructure
rehabilitation  projects in the  metropolitan  New York,  Boston and Los Angeles
areas.  Revenues from real estate operations increased $9.5 million,  from $32.3
million  in  1995 to  $41.8  million  in 1996  due  primarily  to the  Company's
acquisition  during  1996 of an  increased  ownership  position in The Resort at
Squaw Creek joint venture in California.

Along  with  the  increase  in  revenues,   the  total  gross  profit  increased
substantially,  from $1.6  million in 1995 to $38.5  million in 1996,  due to an
overall increase in gross profit from construction  operations of $37.3 million,
from $1.7 million in 1995 to $39 million in 1996.  Overall gross profit  margins
on both  building  and heavy  construction  operations  in 1996  exceeded  those
experienced  in 1995.  The marginal  gross profit from  construction  operations
recognized in 1995 included a pretax charge,  which aggregated $25.6 million, to
provide for a liability related to litigation involving a joint venture in which
the Company was a minority  partner,  and the  Washington  Metropolitan  Transit
Authority on two subway construction projects in Washington,  D.C., and downward
revisions in  estimated  probable  recoveries  on certain  outstanding  contract
claims as well as an overall  reduction in the profit level on a tunnel  project
in the  Midwest.  These  pretax  charges  in 1995,  coupled  with the  increased
construction  revenues in 1996 referred to above and the favorable profit impact
in 1996  of  several  large  infrastructure  projects  underway  in  late  1995,
primarily in the metropolitan New York,  Boston and Los Angeles areas,  resulted
in the  substantial  increase in gross profit from  construction  operations  in
1996.  Real estate  operations  experienced  a gross loss of $.5 million in 1996
compared  to a gross loss of $.1  million in 1995 due to a lower  volume of land
sales in Florida, Arizona and Massachusetts.

General,  administrative  and selling  expenses  decreased  by $2.6  million (or
9.4%),  from $27.2  million in 1995 to $24.6  million in 1996  primarily  due to
continued  emphasis on reducing overall Company overhead expenses in conjunction
with the Company's  re-engineering efforts commenced in prior years, the sale in
June of 1996 of Pioneer Construction, a former subsidiary of the Company located
in West Virginia which performed reclamation projects on abandoned mine lands in
that state,  and the  continuation  of the gradual  down-sizing of the Company's
real estate and environmental remediation construction operations.

Other expense increased $.3 million,  from $.1 million in 1995 to $.4 million in
1996  primarily due to higher bank charges  experienced  in 1996 in  conjunction
with the Company's  renegotiation of certain  provisions of its Revolving Credit
Agreement and Bridge Loan Agreement.

Interest expense increased by $.9 million (or 14.8%),  from $6.1 million in 1995
to $7 million in 1996 due to a higher average level of borrowings during 1996.

The lower than normal tax rate in 1996 is due to the realization of a portion of
the Federal tax benefit  resulting  from the  operating  loss  recorded in 1995.
Because of certain accounting limitations, the Company was not able to recognize
a portion of the tax benefit related to the operating loss experienced in fiscal
1995.

FINANCIAL CONDITION

Working capital  increased $39.7 million,  from $36.5 million at the end of 1995
to $76.2  million at  September  30,  1996  primarily  as a result of  increased
borrowings  under the Company's  Revolving Credit  Agreement.  The current ratio
increased from 1.12:1 to 1.28:1 during this same period.

During  the first nine  months of 1996 the  Company  used $31.5  million in cash
provided from financing  activities,  primarily  from net  borrowings  under its
long-term  credit  facilities,  plus $14.2 million from cash on hand to fund its
construction and real estate operations, including $13.6 million for investments
in or advances to joint ventures.

Long-term  debt at September 30, 1996 was $114.7  million,  an increase of $30.5
million from December 31, 1995.  The long-term  debt to equity ratio at June 30,
1996 was 1.02 to 1, compared to .80 to 1 at December 31, 1995.

                                        9

<PAGE>



The above  factors  reflect  the  Company's  need to rely  heavily on  long-term
financing  arrangements to fund the current working capital  requirements of its
core  construction  business,  primarily  in its  heavy/civil  operations  which
typically  require a long  start-up  period  and  significant  up-front  working
capital,  as well as to fund  cash  shortfalls  experienced  in its real  estate
operations. In addition to internally generated funds, the Company has access to
funds under its $114.5 million  long-term Credit Agreement.  Effective  February
26, 1996, the Company entered into a Bridge Loan Agreement for an additional $15
million through July 31, 1996. Subsequently, this Bridge Loan Agreement has been
extended  through  January  31,  1997.  Additionally,  in July 1996 the  Company
announced  that it had entered into an agreement  with an investor  group led by
Richard C. Blum &  Associates,  L. P. of San  Francisco,  California,  for a $30
million investment in the form of a new issuance of 150,150 shares of cumulative
convertible  junior  preferred  stock in the Company  subject to certain closing
conditions.  Initially, the Company expected to be able to close the transaction
in early October.  However,  certain  regulations of the American Stock Exchange
require  shareholder  approval of the  transaction  in advance,  therefore,  the
anticipated  closing  date of the  transaction  is now  expected by year end. At
September 30, 1996 there was no borrowing capacity available under the Company's
long-term  credit  facility  and $5.8  million  available  under the Bridge Loan
Agreement.

OUTLOOK

The  statements  contained in this Outlook  that are not purely  historical  are
forward-looking  statements  within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the  Securities  Exchange Act of 1934,  including
statements regarding the Company's expectations,  hopes, beliefs,  intentions or
strategies regarding the future. All forward-looking statements included in this
Outlook are based on  information  available  to the Company on the date hereof,
and the  Company  assumes  no  obligation  to  update  any such  forward-looking
statements.  It is important to note that the  Company's  actual  results  could
differ materially from those in such forward-looking statements.

At least until the closing of the new equity  investment  discussed  above,  the
Company's financial resources and short-term liquidity position will continue to
be tight,  resulting in the payment of many vendors beyond the Company's  normal
payment terms.  In the near term, the Company  intends to continue to manage its
cash receipts and  disbursements  as effectively as possible in  anticipation of
closing  the new  equity  investment  and the  receipt of the  proceeds  related
thereto.  In addition,  the Company has been  successful  in  extending  its $15
million  Bridge  Loan  Agreement  until at least  January 31, 1997 as well as in
arranging  for $20 million in  additional  borrowing  capacity  through its bank
credit facility: $10 million via certain bonding arrangements in lieu of posting
letters of credit,  and $10 million via a temporary  loan made  available to the
Company through a participation  under the existing loan agreement by a group of
investors  led by  Richard C. Blum &  Associates,  L. P. of San  Francisco,  the
Company's  potential new equity investor.  This $10 million temporary  financing
will be  repayable  by the  Company  at the  earlier  of the  completion  of the
proposed $30 million equity investment referred to above or January 31, 1997.

In order to generate  cash and reduce the  Company's  dependence on bank debt to
fund the working capital needs of its core construction operations as well as to
lower the Company's  substantial  interest  expense and  strengthen  the balance
sheet in the longer term,  the Company will continue to sell certain real estate
assets as market  opportunities  present  themselves;  to  actively  pursue  the
favorable   conclusion  of  various  construction  claims;  to  focus  new  work
acquisition  efforts on various  niche  markets and  geographic  areas where the
Company has a proven history of success;  to down-size or close  operations with
marginal  prospects  for  success;  to continue to restrict  the payment of cash
dividends on the Company's $1 par value common stock and depositary  convertible
exchangeable  preferred  stock; and to continue to seek ways to control overhead
expenses. In addition, the Company is reviewing all of the Company's real estate
assets and current  strategies related to those assets with the possibility that
a plan may be developed to generate  short term liquidity of up to an additional
$20 million for the Company.  Currently, the Company's strategy has been to hold
its real estate  assets  through the  necessary  development  and  stabilization
periods to achieve full value.  A strategy which  includes  earlier  disposal of
certain of those assets  could  require a write down of such assets to the lower
of carrying  amounts or current  fair values,  less costs to sell.  The specific
assets  or  timing  of  such  sales  has  not  yet  been  determined,  but it is
anticipated that implementation  would require the Company to take a significant
writedown  of its real estate  assets  which could range from $30 million to $80
million on a pretax basis.  If such a writedown  were  required,  it is expected
that it would be done during 1996

                                       10

<PAGE>



after the plan was formalized,  but in advance of the actual sale of properties.
Management  believes that cash generated from operations,  existing credit lines
and additional borrowings,  including the anticipated proceeds from the issuance
of cumulative  convertible  junior  preferred  stock  referred to above,  should
probably be adequate to meet the Company's funding requirements for at least the
next twelve months.  However,  the withdrawal of many commercial lending sources
from both the real estate and  construction  markets and/or  restrictions on new
borrowings  and  extensions  on  maturing  loans by  these  same  sources  cause
uncertainties in predicting liquidity.

Item 3. - Defaults Upon Senior Securities

(a)     None

        As previously  disclosed in the 1995 Form 10-K, in conjunction  with the
        covenants of the  Company's  Amended  Revolving  Credit  Agreement,  the
        Company is required to suspend the payment of quarterly dividends on its
        depositary  convertible  exchangeable  preferred  stock  until  the  $15
        million Bridge Loan  commitment is no longer  outstanding,  if a default
        exists under the terms of the Amended Revolving Credit Agreement,  or if
        the  ratio of  long-term  debt to equity  exceeds  50%.  Therefore,  the
        dividends on the preferred  stock that normally would have been declared
        during  December  of 1995 and March,  June and  September  of 1996,  and
        payable on March 15,  June 15,  September  15, and  December  15,  1996,

the full corporate power and authority to execute and deliver this Agreement and
each other  Transaction  Document  and to  perform  its  obligations  under this
Agreement  and each  other  Transaction  Document.  Seller  has taken all action

this Agreement and each other Transaction Document. This Agreement is, and after
the  Closing  each  other  Transaction  Document  will be, a valid  and  binding
obligation of Seller,  enforceable  in  accordance  with its  respective  terms,
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 that
rights  to  indemnity  and  contribution  may be  limited  by  federal  or state
securities  laws or policies  underlying  such laws. True and complete copies of
the  Articles  of  Organization  and  bylaws  of Seller as in effect on the date

with the terms of its employee  benefit plans as in existence on March 31, 1996,
and 6,925 shares of Common Stock in accordance with the quarterly payment of the

of business and in a manner and in amounts consistent with past practice.

                  (b) All of the  shares  of  Series  B  Cumulative  Convertible
Preferred  Stock  issued at the Closing or issued as  dividends  pursuant to the
Articles of  Organization  and the Certificate of Vote of Directors will be duly
authorized,  validly issued,  fully paid and  nonassessable  and entitled to the
benefits  of, and have the terms and  conditions  set forth in, the  Articles of
Organization  and the  Certificate of Vote of Directors.  The Conversion  Shares
will be reserved and will be duly  authorized  for issuance  and, when issued in

upon or  known to the  Seller  and  have  been  issued  in  compliance  with all
applicable  federal and state securities or "blue sky" laws. No further approval
or authority of the  shareholders or of the Board of Directors of Seller will be
required for the consummation by Seller of the transactions contemplated by this
Agreement and each of the other  Transaction  Documents,  except for approval of
the Shareholder Meeting Matters at the Shareholder Meeting.

                  5.3 SEC Documents.  Each of the SEC Documents,  as of the date
of its filing  with the SEC and as of the  Closing,  did not  include any untrue
statement  of a material  fact or omit to state any material  fact  necessary to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading.

                  5.4  Authority  and  Qualification  of Seller.  Seller has the
corporate  power and authority to own,  lease and operate its  properties and to
conduct its business as described in the SEC Documents and as currently owned or
leased and conducted. Seller is duly qualified to transact business as a foreign
corporation and is in good standing in each jurisdiction in which the conduct of
its business or its  ownership,  leasing or operation of property  requires such
qualification,  other than any failure to be so qualified or in good standing as
would not singly or in the aggregate with all such other failures  reasonably be
expected to have a material adverse effect on the assets,  liabilities,  results
of operations, prospects or condition (financial or otherwise) of Seller and the
Subsidiaries taken as a whole (each a "Material Adverse Effect").

                  5.5 Subsidiaries. Exhibit 22 to Seller's Annual Report on Form
10-K  for the year  ended  December  31,  1995 as  filed  with the SEC  ("Annual

required  to be set forth in  Exhibit  21 by the  regulations  of the SEC.  Each
Subsidiary has been duly  incorporated or organized and is validly existing as a
corporation  or  other  legal  entity  in good  standing  under  the laws of the
jurisdiction of its incorporation or formation, has the corporate or other power
and  authority  to own,  lease and  operate  its  properties  and to conduct its
business as described in the SEC Documents and as currently  owned or leased and
conducted and is duly qualified to transact business as a foreign corporation or
other legal entity and is in good standing (if applicable) in each  jurisdiction
in which the conduct of its business or its  ownership,  leasing or operation of
property requires such qualification,  other than any failure to be so qualified
or in good standing as would not singly or in the aggregate  with all such other
failures  reasonably be expected to have a Material  Adverse  Effect.  Except as
disclosed  in the SEC  Documents  filed  with the SEC  prior to the date of this
Agreement, all of the outstanding capital stock of each Subsidiary has been duly
authorized and validly issued,  is fully paid and  nonassessable and all capital
stock of Subsidiaries owned by Seller,  directly or through  Subsidiaries (other
than directors' qualifying shares), are free and clear of any mortgage,  pledge,
lien,  security  interest,   restriction  upon  voting  or  transfer,  claim  or
encumbrance of any kind ("Encumbrance")  (other than such transfer  restrictions
as may exist under federal and state  securities  laws), and there are no rights
granted to or in favor of any third party (whether


                                     - 12 -

<PAGE>



acting in an  individual,  fiduciary  or other  capacity)  other than  Seller to
acquire  any such  capital  stock,  any  additional  capital  stock or any other
securities of any Subsidiary.

                  5.6  Outstanding  Securities.  Except  as set forth in the SEC
Documents  filed with the SEC prior to the date of this  Agreement and except as
contemplated  by this  Agreement,  there are no  outstanding  (a)  securities or
obligations of Seller  convertible into or exchangeable for any capital stock of
Seller, (b) warrants, rights or options to subscribe for or purchase from Seller
any such capital stock or any such  convertible  or  exchangeable  securities or
obligations  or (c)  obligations  of  Seller  to  issue  such  shares,  any such
convertible or  exchangeable  securities or  obligations,  or any such warrants,
rights or options.

                  5.7 No Contravention,  Conflict,  Breach,  Etc. The execution,
delivery  and  performance  of each  of this  Agreement  and  each of the  other
Transaction  Documents by Seller and the consummation of the transactions herein
and therein  contemplated  will not (a) contravene any provision of the Articles
of Organization,  by-laws or other organization documents of it or of any of the
Subsidiaries,  or (b) conflict with or result in a breach or violation of any of
the terms and  provisions  of, or constitute a default  under,  or result in the
creation or imposition  of any lien,  charge or  encumbrance  upon any assets or
properties  of it or of  any of  the  Subsidiaries  under,  any  statute,  rule,
regulation, order or decree of any Government Entity having jurisdiction over it
or the  Subsidiaries  or any of its or their  respective  properties,  assets or
operations, or any indenture,  mortgage, loan agreement, note or other agreement
or instrument for borrowed  money,  any guarantee of any agreement or instrument
for  borrowed  money  or any  lease,  permit,  license  or  other  agreement  or
instrument to which it or any of the  Subsidiaries  is a party or by which it or
any  such  Subsidiary  is bound or to which  any of the  properties,  assets  or
operations  of it or any such  Subsidiary  is subject  which  conflict,  breach,
violation, default, creation or imposition has, or will have, individually or in
the aggregate, a Material Adverse Effect.

                  5.8  Consents.  No consent,  approval,  authorization,  order,
registration,  filing or qualification  of or with any (a) Government  Entity or
(b) other third  party  (whether  acting in an  individual,  fiduciary  or other
capacity) is required for the consummation of the  transactions  contemplated by
this Agreement or by any of the other  Transaction  Documents to be performed by
Seller, except (i) shareholder approval at the Shareholder Meeting, (ii) such as
will have been  obtained and made and will be in full force and effect as of the
Closing  and (iii) such as may be  required  under the Act and state  securities
laws in connection with the  performance by Seller of its obligations  under the
Registration Rights Agreement.

                  5.9 No Existing  Violation or Default.  Neither Seller nor any
of the  Subsidiaries  is in  violation  of (a) its  charter,  by-laws  or  other
organization  documents or (b) any applicable law, ordinance,  administrative or
governmental  rule or  regulation  or (c) any order,  decree or  judgment of any
Government  Entity  having  jurisdiction  over  Seller  or any  Subsidiary.  The
properties, assets and operations of Seller and the Subsidiaries are in


                                     - 13 -

compliance in all material respects with all applicable  federal,  state,  local
and foreign laws, rules and regulations, orders, decrees, judgments, permits and
licenses relating to public and worker health and safety.

                  5.10     Environmental Matters.

Environmental  Claim,  and  Seller and the  Subsidiaries  have  complied  in all
material  respects  with all  regulatory  requirements  relating to the storage,

Environmental   Subsidiary's  insurance  policies,  except  where  such  claims,
actions,  causes of  action or other  written  notice  will not have a  Material
Adverse Effect.

Subsidiaries  are in compliance in all material  respects with their  respective
obligations under such Licenses,  with such exceptions as individually or in the

periods have  expired),  and no  deficiencies  were asserted as a result of such
examinations that have not been resolved and fully paid;  neither Seller nor any
Subsidiary has granted any requests,  agreements,  consents or waivers to extend
the statutory  period of  limitations  applicable to the assessment of any Taxes
for which Seller or any Subsidiary may be liable;

                  (e) there are no Tax liens  outstanding  against  any  assets,

                  (j) the aggregate  unpaid Taxes of the Seller and Subsidiaries
did not, as of March 31, 1996, exceed the reserve for Tax liability (rather than
any reserve for deferred Taxes established to reflect timing differences between
book and Tax  income)  set  forth  in the  most  recent  SEC  Document,  and the
aggregate  unpaid Taxes of Seller and Subsidiaries do not exceed that reserve as
adjusted for payments and accruals  made through the Closing Date in  accordance
with the past custom and practice of Seller and Subsidiaries in filing their Tax
Returns; and

                                    - 17 -

                  (d) neither  Seller nor any  Subsidiary  has  experienced  any
significant  work stoppage nor has Seller or any Subsidiary  been a party to any
proceedings  before the National Labor  Relations Board for the past three years
or been a party to any arbitration proceeding arising out of or under collective
bargaining agreements for the past three years;

                  (e)  there is no  charge  or  compliance  proceeding  actually
pending  or  threatened  against  Seller  or any  Subsidiary  before  the  Equal
Employment  Opportunity  Commission  or  any  state,  local  or  foreign  agency
responsible for the prevention of unlawful employment practices; and

                  (f) neither Seller nor any  Subsidiary has received  notice of
the intent of any Government Entity  responsible for the enforcement of labor or
employment laws to conduct an  investigation,  and no such  investigation  is in
progress.

                  5.16 No Illegal or Improper  Transactions.  Neither Seller nor
any Subsidiary has, nor, to the Knowledge of Seller,  has any director,  officer
or employee of Seller or any Subsidiary,  directly or indirectly,  used funds or
other assets of Seller or any Subsidiary,  or made any promise or undertaking in
such  regard,  for (a)  illegal  contributions,  gifts,  entertainment  or other
expenses  relating to  political  activity;  (b) illegal  payments to or for the
benefit of governmental officials or employees, whether domestic or foreign; (c)

there have been no false or  fictitious  entries made in the books or records of

                  5.17 Contracts.  All of Seller's  material  contracts that are
required to be described in the SEC Documents or to be filed as exhibits thereto
are described in the SEC Documents or filed as exhibits  thereto and are in full
force and effect.  Neither Seller nor any of the  Subsidiaries  nor, to the best
knowledge of Seller,  any other party is in breach of or default  under any such
contracts except for such breaches and defaults as in the aggregate have not had
and would not have a Material Adverse Effect.

                  5.18  Finder's  Fees.  Except  as  set  forth  on  the  Perini
Disclosure  Schedule,  no broker,  finder or other  party is entitled to receive

finder's  fee or any  other  fee,  commission  or  payment  as a  result  of the
transactions contemplated by this Agreement.

statements and related  schedules and notes included in the SEC Documents comply
in all material  respects with the  requirements of the Exchange Act and the Act
and the rules and regulations of the SEC thereunder, were prepared in accordance
with generally accepted accounting  principles  consistently  applied throughout
the period involved and fairly present the financial condition,


                                     - 19 -

<PAGE>



results of  operations,  cash flows and changes in  stockholders'  equity of the
Seller and the  Subsidiaries  at the dates and for the  periods  presented.  The
unaudited  quarterly  consolidated  financial  statements  and the related notes
included in the SEC Documents present fairly the financial condition, results of
operations  and cash flows of Seller and the  Subsidiaries  at the dates and for
the  periods  to which  they  relate,  subject  to  year-end  audit  adjustments
(consisting only of normal recurring accruals), have been prepared in accordance
with generally  accepted  accounting  principles  applied on a consistent  basis
except  as  otherwise   stated  therein  and  have  been  prepared  on  a  basis
substantially  consistent with that of the audited financial statements referred
to above except as otherwise stated therein.

                  5.20     Employee Benefit Plans; ERISA.

                  (a)  Schedule  5.20(a)  lists  each  Seller  Plan.  Seller has

                  (b) (i) none of the  Seller  Plans is or has been  subject  to
Title IV of the Employee  Retirement  Income  Security  Act of 1974,  as amended
("ERISA"),  (ii) there is no outstanding or contingent  liability under Title IV
of ERISA with respect to any Seller Plan; (iii) full and timely payment has been

                  (c)  Neither  Seller  nor  any  of  its  ERISA  Affiliates  is
contributing  to or is obligated to contribute to a  Multiemployer  Pension Plan
nor does Seller or any Subsidiary have any outstanding liability with respect to
any  Multiemployer  Pension  Plan.  Neither  the  Seller  nor  any of its  ERISA
Affiliates  has incurred or expects to incur any  liability,  except for ongoing
funding  obligations,  under Title IV of ERISA with respect to any Multiemployer
Pension Plan.

                  (d) Neither  Seller nor any  Subsidiary  has, since January 1,
1996, made any commitment (i) to create any additional  Seller Plan or to modify
in any material respect any existing Seller Plan covering  employees  engaged in
its  businesses or (ii) to create or modify in any material  respect any salary,
bonus, and/or profit-sharing arrangement covering such employees.

                  (e) Neither  Seller nor any Subsidiary and no Seller Plan (nor
any trust  created  thereunder  nor any trustee or  administrator  thereof)  has
engaged in any  transaction,  taken any action,  or failed to take any action in
connection  with  which  Seller  or any  Subsidiary  could be  subject  (whether
directly or indirectly or as  indemnitor)  to any liability  (whether  actual or
contingent) or material civil penalty assessed pursuant to Sections 409, 502(c),
502(i),  502(l),  or 4071 of ERISA or material tax or material  penalty  imposed
pursuant to Sections 4971, 4972, 4975 to 4980A, or 5000 of the Code. All returns
and  reports  that were  required  to be filed with any  Government  Entity with
 respect to Seller Plans have been filed on a timely basis and were correct and
complete in all material respects.

                  (f) There are no pending,  threatened,  or anticipated  claims
(other than routine claims for benefits) by, on behalf of, or against any Seller
Plan.  No Seller Plan is presently  under audit or  examination  (nor has notice
been  received  of a  potential  audit) by the  Internal  Revenue  Service,  the
Department of Labor, or Pension Benefit Guaranty Corporation,  nor are there any
matters  pending  with  respect to any  Seller  Plan with the  Internal  Revenue
Service under its Voluntary Compliance Resolution program, its Closing Agreement
Program, or other similar programs.

                  (g)  Each  Seller  Plan  has  been  operated  in all  material
respects in accordance with its terms and with applicable Law.

                  (h) Except for ongoing funding obligations, no liability under
Title IV of ERISA  has been or is  expected  to be  incurred  by  Seller  or any
Subsidiary  with respect to any ongoing,  frozen or terminated  "single-employer
plan," within the meaning of Section  4001(a)(15)  of ERISA (a "Title IV Pension
Plan"),  currently or formerly maintained by any of them, or any single-employer
plan (an "ERISA  Affiliate  Plan") of any entity that is considered one employer
with the  Seller  under  Section  4001 of ERISA or  Section  414 of the Code (an
"ERISA  Affiliate").  Neither any Seller Plan which is a funded employee pension
benefit plan ("Pension  Plan") nor any ERISA  Affiliate Plan has an "accumulated
funding deficiency"


                                     - 21 -

<PAGE>



(whether or not waived) within the meaning of Section 412 of the Code or Section
302 of ERISA. Neither Seller nor any Subsidiary has provided,  or is required to
provide, security to any Pension Plan or to any ERISA Affiliate Plan pursuant to
Section  401(a)(29) of the Code.  Neither Seller nor any ERISA Affiliate is, or,
within the last seven years has been, a participating  employer under a multiple
employer plan within the meaning of Section 4063 or 4064 of ERISA.

                  (i) Except for the Employment  Contracts referenced in Section
3.6, the  consummation of the  transactions  contemplated by this Agreement will
not (i) entitle any employee to severance pay, unemployment  compensation or any
other payment or (ii) accelerate the timing of any payment or the vesting of any
rights or increase  the amount of any  compensation  due any  employee or former
employee.  Each Seller Plan may be  unilaterally  amended or terminated  without
liability  except as to benefits  accrued  thereunder  prior to the amendment or
termination.

                  5.21  Contingent  Liabilities.  Except as fully  reflected  or
reserved  against in the financial  statements  included in the Annual Report or
the Quarterly Report, or disclosed in the footnotes  contained in such financial
statements,   Seller  and  Subsidiaries   had  no  liabilities   (including  tax
liabilities) at the date of such financial  statements,  absolute or contingent,
that were  material  either  individually  or in the  aggregate  to  Seller  and
Subsidiaries taken as a whole. Except as so reflected,  reserved,  or disclosed,
Seller and Subsidiaries have no commitments which are materially  adverse either
individually or in the aggregate to Seller and Subsidiaries taken as a whole.

                  5.22 No Material  Adverse Change.  Since the latest date as of
which  information  with  respect  to the  following  items  is given in the SEC
Documents  filed  prior  to  July  24,  1996  and  except  as  contained  in the
Transaction Documents and the transactions  contemplated therein,  there has not
been:

                  (a) any change that by itself or together  with other  changes
has a Material Adverse Effect; or

                  (b) any damage, destruction or loss (whether or not covered by
insurance)  materially adversely affecting the properties or business of Seller;
or

                  (c) except as  provided  for in this  Agreement  and the other
Transaction Documents,  any change in the authorized capital of Seller or in its
outstanding  securities or any change in its ownership interests or any grant of
any options, warrants, calls, conversion rights or commitments; or

                  (d) any declaration or payment of any dividend or distribution
in respect of the capital stock or any direct or indirect  redemption,  purchase
or other acquisition of any of the capital stock of Seller; or

                  (e) any increase in the compensation, bonus, sales commissions
or fee  arrangements  payable  or to  become  payable  by  Seller  to any of its
officers directors,  stockholders,  employees, consultants or agents, except for
ordinary and customary  bonuses and salary increased for employees in accordance
with past practice; or

                  (f) any work interruptions,  labor grievances or claims filed,
or any  similar  event  or  condition  of any  character,  materially  adversely
affecting the business or future prospects of Seller; or

                  (g)  any  sale  or  transfer,  or any  agreement  to  sell  or
transfer, any material assets property or rights of Seller to any person; or

                  (h) any cancellation, or agreement to cancel, any indebtedness
or other  obligation  owing to Seller,  provided  that Seller may  negotiate and
adjust  bills in the course of good faith  disputes  with  customers in a manner
consistent with past practice; or

                  (i)  any  plan,   agreement   or   arrangement   granting  any
preferential  rights to purchase  or acquire any  interest in any of the assets,
property or rights of Seller or  requiring  consent of any party to the transfer
and assignment of any such assets, property or rights; or

                  (j) any  purchase or  acquisition  of, or  agreement,  plan or
arrangement  to purchase or acquire,  any property,  rights or assets outside of
the ordinary course of business of Seller; or

                  (k) any waiver of any material rights or claims of Seller; or

                  (l) any  material  breach,  amendment  or  termination  of any
material contract,  agreement, license, permit or other right to which Seller is
a party; or

                  (m) any  transaction by Seller outside the ordinary  course of
business; or

                  (n) any capital  expenditures or commitment by Seller,  either
individually or in the aggregate, exceeding $5,000,000.00; or



                                     - 23 -

                  (o) any change in accounting  methods or practices  (including
any change in depreciation  or amortization  policies or rates) by Seller or the
revaluation by Seller of any of its assets; or

                  (p) any  creation  or  assumption  by Seller of any  mortgage,
pledge,  security interest or lien or other encumbrance on any asset (other than
liens arising under existing lease financing arrangements which are not material
and liens for taxes not yet due and payable); or

                  (q) any entry into, amendment of, relinquishment,  termination
or non-renewal by Seller of any contract, lease transaction, commitment or other
right or obligation that would have a Material Adverse Effect; or

                  (r) any loan by Seller to any person or entity,  incurring  by
Seller,  of any  indebtedness,  guaranteeing  by  Seller  of  any  indebtedness,

securities of others; or

                  (s) the  commencement  or notice or threat of  commencement of
any  lawsuit  or  proceeding  against or  investigation  of Seller or any of its
affairs; or

                  (t)  negotiation  or  agreement  by Seller or any  officer  or
employee thereof to do any of the things described in the preceding  clauses (a)
through (s) (other than negotiations with RCBA and its representatives regarding
the transactions contemplated by this Agreement).

                  5.23 Investment Company. Seller is not an "investment company"
within the meaning of the Investment Company Act of 1940, as amended.

                  5.24 Exemption from  Registration;  Restrictions  on Offer and
Sale of Same or Similar Securities.  Assuming the representations and warranties
of RCBA and Purchaser set forth in Article VI hereof are true and correct in all
material  respects,  the  offer and sale of the  Shares  made  pursuant  to this
Agreement will be exempt from the registration  requirements of the Act. Neither
Seller nor any Person acting on its behalf has, in connection  with the offering
of the  Shares,  engaged  in (a) any form of  general  solicitation  or  general
advertising (as those terms are used within the meaning of Rule 502(c) under the
Act), (b) any action  involving a public  offering within the meaning of Section
4(2) of the Act, or (c) any action which would require the  registration  of the
offering  and sale of the Shares  pursuant  to this  Agreement  under the Act or
which would violate  applicable state securities or "blue sky" laws.  Seller has
not made and will not make, directly or indirectly,  any offer or sale of Shares
or of securities of the same or a similar class as the Shares if as a result the
offer  and sale of Shares  contemplated  hereby  could  fail to be  entitled  to
exemption from the registration requirements


                                     - 24 -

of the Act.  As used herein, the terms "offer" and "sale" have the meanings 
specified in Section 2(3) of the Act.

                  5.25 Disclosure.  No representation or warranty concerning the
Seller or any Subsidiary in this Agreement or any Exhibit or Schedule hereto, or
contained in any certificate or instrument delivered or to be delivered by or on
behalf of Seller or any  Subsidiaries  pursuant to this  Agreement,  contains or
will  contain an untrue  statement  of material  fact,  or omits or will omit to
state a material  fact  necessary  to make the  statements  contained  herein or
therein, in light of the circumstances in which they were made, not misleading.

                                   ARTICLE VI
                         REPRESENTATIONS AND WARRANTIES
                              OF RCBA AND PURCHASER

                  RCBA and  Purchaser  each hereby  represents  and  warrants to
Seller that:

                  6.1 Organization,  Good Standing,  Power, Authority, Etc. Each
of RCBA and  Purchaser  has the full power and  authority to execute and deliver
this  Agreement  and the  Registration  Rights  Agreement,  and to  perform  its
obligations under this Agreement and the Registration Rights Agreement.  Each of
RCBA and  Purchaser  has taken all action  required  by law,  its  charter,  its
by-laws or otherwise  required to be taken by it to authorize  the execution and
delivery  of  this  Agreement  and the  Registration  Rights  Agreement  and the
consummation of the  transactions  contemplated to be performed by it hereby and
thereby. Each of this Agreement and the Registration Rights Agreement is a valid
and binding agreement of RCBA and Purchaser,  enforceable in accordance with its
respective  terms,  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.

                  6.2 No  Conflicts;  No  Consents.  Neither the  execution  and
delivery  of  this  Agreement  and the  Registration  Rights  Agreement  nor the
consummation by Purchaser of the purchase  contemplated hereby will (i) conflict
with,  or result in a breach of, any provision of its  partnership  agreement or
(ii)  violate  any  statute or law or any  judgment,  order,  writ,  injunction,
decree,  rule  or  regulation  applicable  to  RCBA or  Purchaser.  No  consent,
authorization  or approval of, or declaration,  filing or registration  with, or
exemption by, any governmental or regulatory authority is required in connection
with the execution and delivery of, and the  performance by RCBA or Purchaser of
their obligations under, this Agreement or the Registration  Rights Agreement or
the  consummation by RCBA or Purchaser of the transactions to be performed by it
as contemplated hereby and thereby.

                  6.3 Investment Intent,  Etc. Purchaser (a) has such knowledge,
sophistication  and  experience  in business  and  financial  matters that it is
capable of evaluating  the merits and risks of an investment in the Shares,  (b)
fully understands the nature,  scope and duration of the limitations on transfer
contained in this Agreement,  (c) can bear the economic risk of an investment in
the  Shares  and can  afford  a  complete  loss of such  investment,  and (d) is
purchasing  the Shares for  investment  and not with a view to, or for a sale in

acknowledges  (y) receipt of the SEC  Documents  filed with the SEC prior to the
date of this  Agreement  and (z)  that  such  Purchaser  has been  afforded  the
opportunity to ask such questions as it has deemed  necessary of, and to receive
answers  from,  representatives  of Seller  concerning  the  merits and risks of
investing in the Shares,  and to obtain such additional  information that Seller
possesses  or can  acquire  without  unreasonable  effort  or  expense  that  is
necessary to verify the accuracy and  completeness of the information  contained
in such SEC Documents.

                  6.4 Litigation. There is no claim, suit, action, proceeding or
investigation  (whether at law or equity,  before or by any Government Entity or
before  any  arbitrator)  pending  or, to the  knowledge  of RCBA or  Purchaser,
threatened against or affecting RCBA or Purchaser, the outcome of which would in
any manner  impair the ability of RCBA or Purchaser  to perform its  obligations
hereunder or against the transactions contemplated by this Agreement.

                  6.5 Certain Fees. Neither RCBA nor Purchaser has entered into,
nor  will  enter  into,  during  the  term of  this  Agreement,  any  agreement,
arrangement or understanding  with any Person that will result in the obligation
of Seller to pay any finder's fee,  brokerage  commission or similar  payment in
connection with the transactions contemplated hereby.

                  6.6 Financial  Ability.  Purchaser is financially  capable and
has, or will have upon the Closing  Date,  sufficient  cash and other  resources
available to complete the  transactions  contemplated by this Agreement upon the
terms and conditions set forth in this Agreement.

                  7.1 Restrictive  Legends.  Purchaser covenants and agrees with
Seller that Purchaser will not dispose of any of Purchaser's  shares of Series B
Cumulative  Convertible  Preferred  Stock or  Conversion  Shares  (unless,  with
respect to such Conversion Shares, such Conversion Shares were previously issued
pursuant to an effective  registration  statement under the Act) except pursuant
to (a) an effective  registration  statement  under the Act or (b) an applicable
exemption from registration under the Act. In connection with any sale by


                                     - 26 -

<PAGE>



Purchaser  pursuant to clause (b) of the  preceding  sentence,  Purchaser  shall
furnish to Seller an opinion of counsel reasonably satisfactory to Seller to the
effect that such exemption  from  registration  is available in connection  with
such sale.

                  7.2 Executive  Committee.  Seller shall,  immediately upon the
issuance of the Shares, reconstitute its Executive Committee such that:

                  (a) the Executive  Committee  shall have five voting  members,
three of whom shall be designated directors of Seller by the Purchaser of Series
B  Cumulative  Convertible  Preferred  Stock  and two of whom  shall be David B.
Perini  and/or  such  other  director(s)  as may be  designated  by the Board of
Directors of Seller (excluding directors designated by the holders of the Series
B Cumulative  Convertible Preferred Stock pursuant to the Certificate of Vote of
Directors);   provided,  however,  that  the  holders  of  Series  B  Cumulative
Convertible  shall not be entitled to designate any greater number of members of
the  Executive  Committee  than the number  which they are entitled to designate
pursuant to the terms of the Certificate of Vote of Directors, and

                  (b)  the  Executive  Committee  shall  meet  regularly  and as
needed, in Person or by telephone, and

                  (c) the Board of  Directors  shall  delegate to the  Executive
Committee  its power set forth in Section 4 of  Seller's  by-laws to oversee and
direct the CEO of Seller, and

                  (d) the  Board of  Directors  shall  have  adopted  the  Bylaw
Amendments as set forth in Exhibit 1.6 to prevent the modification of the powers
of the Executive  Committee set forth in this Section 7.2 and/or the dissolution
of the Executive Committee, and

                  (e) the  provisions of this Section shall  terminate and be of
no further  force and  effect  when and if the  holders  of Series B  Cumulative
Convertible  Preferred  Stock shall not be entitled to  designate  more than one
director pursuant to the terms of the Certificate of Vote of Directors.

                  7.3 Seller's  Board of Directors.  Seller  shall,  immediately
upon  issuance of the Shares,  expand its Board of  Directors  by three  members
("New  Directors"),  one of whom  shall be a Class I  director,  another of whom
shall  be a Class  II  director  and the  third  of whom  shall  be a Class  III
director,   shall  appoint  persons  designated  by  Purchaser  to  these  three
directorships,  and shall not remove such New Directors  without  cause.  For so
long as Purchaser is entitled to nominate at least one  Designated  Director (as
defined in the Certificate of Vote of Directors)  pursuant to the Certificate of
Vote of Directors, Seller shall appoint a


                                     - 27 -

                  7.6 Removal of Legends.  After  termination of the requirement
that all or part of such legend be placed upon a certificate, Seller shall, upon
receipt  by  Seller  of  evidence  reasonably   satisfactory  to  it  that  such
requirement  has  terminated  and upon the  written  request  of the  holders of
Conversion Shares issue  certificates for the Conversion Shares that do not bear
such legend.

                  7.7  Pre-Closing  Activities.  From and after the date of this
Agreement until the Closing,  each of Seller,  RCBA and Purchaser shall act with
good faith towards, and shall use commercially reasonable efforts to consummate,
the transactions  contemplated by this Agreement,  and none of Seller,  RCBA, or
Purchaser  will take any action  that would  prohibit  or impair its  ability to
consummate the transactions contemplated by this Agreement.

                  7.8  Information.  So long as any of the  Series B  Cumulative
Convertible  Preferred Stock or the Conversion  Shares are  outstanding,  Seller
shall  file  with the SEC the  annual  reports  and  quarterly  reports  and the
information,  documents and other reports that are required to be filed with the
SEC pursuant to Sections 13 and 15 of the Exchange Act, whether


                                     - 29 -

<PAGE>



or not Seller has or is required to have a class of securities  registered under
the  Exchange  Act and  whether or not Seller is then  subject to the  reporting
requirements  of the Exchange Act, at the time Seller is or would be required to
file the same with the SEC and, promptly after Seller is or would be required to
file such reports, information or documents with the SEC, to mail copies of such
reports,  information  and  documents  to the holders of the Series B Cumulative
Convertible  Preferred  Stock and the Conversion  Shares at their  addresses set
forth in the register of Shares and Conversion Shares maintained by the transfer
agent therefor.

                  7.9 Shareholder  Meeting.  In connection with the next meeting
of the shareholders of Seller ("Shareholder  Meeting"),  Seller shall recommend,
and shall use  commercially  reasonable  efforts  (including the preparation and
circulation of the Proxy Statement) to obtain,  the approval of such holders for
the Transaction Documents, and the transactions  contemplated by the Transaction
Documents,  and  the  ratification  of the  Bylaw  Amendments  (such  items  the
"Shareholder Meeting Matters").

                  7.10  Proxy   Statement.   Seller  covenants  that  the  Proxy
Statement  will not include any untrue  statement of a material fact, or omit to
state any material fact,  necessary to make the statements therein, in the light
of the  circumstances  under  which they were made,  not  misleading;  provided,
however,  Seller's  covenant  shall not encompass any  information  in the Proxy
Statement  that was  furnished  in  writing  to the  Seller  by or on  behalf of
Purchaser or RCBA for use specifically in connection with the preparation of the
Proxy  Statement.  The Proxy Statement  shall not be filed,  and no amendment or
supplement to the Proxy Statement shall be made, without  consultation with RCBA
and Purchaser. Seller shall notify RCBA and Purchaser promptly of the receipt by
it of any  comments  from the SEC or its staff and of any request by the SEC for
amendments  or  supplements  to the Proxy  Statement  and shall  supply RCBA and
Purchaser with copies of all correspondence  between it and its representatives,
on the one hand,  and the SEC or the  members of its staff,  on the other  hand,
with respect to the Proxy Statement.

                  7.11   Registration   Rights.   Subject  to  approval  by  the
shareholders of Seller,  Conversion Shares shall be Registrable  Securities,  as
defined in the Registration Rights Agreement, and the holders of such Conversion
Shares shall be entitled to the rights of such a holder  under the  Registration
Rights Agreement.

                  7.12 Stock  Exchange  Listing.  Subsequent  to approval by the
shareholders  of  the  Seller  of  the   Shareholder   Meeting  Matters  at  the
Shareholders  Meeting,  Seller shall take all steps necessary to ensure that the
Conversion Shares are approved for listing, subject to notice of issuance by the
American  Stock Exchange and any other  securities  exchange on which the Common
Stock is listed.

                  7.13 HSR. To the extent applicable, Seller, RCBA and Purchaser
shall make all filings and furnish all information  required with respect to the
transactions contemplated by


                                     - 30 -

<PAGE>



this  Agreement  by the HSR Act and shall use their  best  efforts to obtain the
early  termination  of the waiting  period  thereunder,  provided  that  neither
Seller,  RCBA nor  Purchaser  shall be  required  to agree to dispose of or hold
separate any portion of its business or assets.

                  7.14     Acquisition Proposals.

                  (a) Prior to the Closing,  Seller  agrees that neither  Seller
nor any Subsidiary nor any of the respective officers and directors of Seller or
any of the Subsidiaries  shall, and Seller shall direct and use its best efforts
to  cause  its  employees,  agents  and  representatives   (including,   without
limitation,  any investment banker, attorney or accountant retained by Seller or
any Subsidiary) not to, initiate, solicit or encourage,  directly or indirectly,
any  inquiries  or the  making  of any  proposal  or offer  (including,  without
limitation,  any proposal or offer to  stockholders of Seller) with respect to a
merger,  consolidation or similar transaction involving,  or any purchase of all
or any substantial  portion of the assets or any equity securities of, Seller or
any of the Subsidiaries (any such proposal or offer being  hereinafter  referred
to as an "Acquisition  Proposal") or engage in any negotiations  concerning,  or
provide any confidential  information or data to, or have any discussions  with,
any Person relating to an Acquisition Proposal, or otherwise facilitate directly
or  indirectly  any  effort  or  attempt  to make or  implement  an  Acquisition
Proposal; and

                  (b) Seller will  immediately  cease and cause to be terminated
any existing activities,  discussions or negotiations with any parties conducted
heretofore with respect to any of the foregoing.  Seller will take the necessary
steps to inform the  individuals  or entities  referred to in the first sentence
hereof of the  obligations  undertaken in this subsection  7.14(b).  Seller will
notify RCBA and  Purchaser  immediately  if any such  inquiries or proposals are
received by, any such information is requested from, or any such negotiations or
discussions  are sought to be initiated or  continued  with RCBA and  Purchaser.
Nothing contained in this Agreement shall prohibit Seller and its directors from
(i) pursuing  Acquisition  Proposals if, in the exercise of Seller's  directors'
good faith  judgment  (which  judgment is based upon the advice of  independent,
outside  legal  counsel)  their  fiduciary  duties to Seller's  shareholders  so
require,  (ii) making to the stockholders any  recommendation and related filing
with the SEC, as required by Rules 14e-2 and 14d-9 under the Exchange  Act, with
respect to any tender offer, or (iii) from informing the  stockholders of Seller
in the proxy materials with respect to the  Shareholder  Meeting to consider the
transactions  contemplated by this Agreement of information  that is material to
the vote with respect to such transactions.

                  7.15 Publicity.  Seller,  RCBA and Purchaser will consult with
each other and obtain each other's  consent  before issuing any press release or
otherwise  making  any  public  statements  with  respect  to  the  transactions
contemplated  hereby and shall not issue any such press release or make any such
public  statement  prior to such  consultation  and  consent,  except  as may be
required by law or by  obligations  pursuant to any listing  agreement  with any
securities exchange.

                  7.16 Reservation of Shares.  Seller shall at all times reserve
and keep  available,  out of its authorized and unissued  stock,  solely for the
purpose of effecting the conversion of Series B Cumulative Convertible Preferred
Stock,  such number of shares of its Common Stock free of  preemptive  rights as
shall  from time to time be  sufficient  to effect  the  conversion  of Series B
Cumulative Convertible Preferred Stock from time to time.

                  7.17   Confidentiality.   Each  of  RCBA  and  the   Purchaser
recognizes and acknowledges  that it has in the past,  currently has, and in the
future may possibly have, access to certain confidential  information of Seller.
Each of RCBA  and  Purchaser  agrees  that it  will  not  disclose  confidential
information with respect to Seller to any person, firm, corporation, association
or other  entity for any  purpose  or reason  whatsoever,  except to  authorized
representatives of Seller and to counsel and other advisers,  provided that such
advisers  (other than counsel) agree to the  confidentiality  provisions of this
Section 7.17, unless (i) such information  becomes known to the public generally
through no fault of RCBA or Purchaser, (ii) disclosure is required by law or the
order of any governmental  authority under color of law, or (iii) the disclosing
party  reasonably  believes that such  disclosure is required in connection with
the defense of a lawsuit against the disclosing party,  provided,  that prior to
disclosing any information  pursuant to clauses (i), (ii), or (iii) above,  RCBA
and/or Purchaser shall, if possible, give prior written notice thereof to Seller
and provide Seller with the opportunity to contest such disclosure.

                  7.18  Use of  Proceeds.  The net  proceeds  of the sale of the
Shares  will be used  by  Seller  and its  Subsidiaries  for  general  corporate
purposes,  and shall not,  without the prior written consent of Purchaser (which
consent may be withheld in its sole  discretion) be used to pay dividends or pay
down or reduce  any debt or  securities  senior  in  liquidation  preference  or
dividend  to the Shares  ("Action"),  provided,  however,  that no such  written
consent  of  Purchaser  shall be  required  where a majority  of the  Designated
Directors  (as defined in the  Certificate  of Vote of  Directors)  approves the
proposed  Action.  Seller  intends  that  such  net  proceeds  will be used  for
investment in the continuing businesses of Seller and the Subsidiaries.

                  7.19  Maintenance of Business.  Seller  covenants that between
the date of this  Agreement  and  Closing,  it shall and shall cause each of its
Subsidiaries to:

                  (a)  conduct  its  business  (including,  but not  limited to,
making loans,  paying directors,  officers and employees,  including any salary,
bonus,  or  other  compensation  policy,  disposing  or  acquiring  assets,  and
incurring  liabilities)  only  in the  ordinary  course,  consistent  with  past
practice,

<PAGE>



                  (b)  use  commercially  reasonable  efforts  to  preserve  its
business  organizations  intact,  to retain the services of its present officers
and  employees  and to preserve the good will of the suppliers and customers and
others having business relations with it,

                  (c) comply in all material  respects with all laws that may be
applicable to its business,  (d) not make any noncash distributions or dividends
to its stockholders, and

                  (e) comply with its stated official  accounting  policies with
respect to charge-offs and loss provisions.

                  Subject to the  foregoing,  any  transaction or action that is
not in the ordinary course of business,  consistent with Seller's past practice,
shall be subject to the prior written consent of Purchaser.

Vote of Directors,  (x) as a result of a stock split,  stock dividend or similar

directly  from  Seller  pursuant  to a  distribution  to  stockholders  or  from
acquiring  such Rights  directly  from Seller;  and provided,  further,  that if
during the Standstill Period, as a result of a business combination  transaction

Securities,  with the exception of any group all of whose members are Affiliates
of Purchaser (such group, excluding such Affiliates, a "13D Group").

                  8.2 Voting.  Nothing in this Article VIII shall  preclude RCBA

been waived in  accordance  with the terms  hereof for all  purposes  and at all
times by the parties to whom the benefit of such performance is to be rendered).

the other parties. RCBA or Purchaser may assign to one or more of its affiliated
partnerships  its  obligations  hereunder in whole or in part,  but shall not be
relieved of such obligations.

contracts  made and performed  within the State of Delaware,  without  regard to

the remainder of this  Agreement in the manner which it determines  most closely

                  14.5 Headings.  The index and section  headings herein are for

                  14.6 Entire Agreement.  This Agreement together with the other

oral,  among  Seller,  RCBA and  Purchaser,  or  between  or among  any  agents,
representatives,  parents, subsidiaries, affiliates, predecessors in interest or
successors in interest, with respect to the subject matter hereof.

                  14.7   Counterparts.   This   Agreement  may  be  executed  in
counterparts,  each of which shall be deemed to be an original  and all of which
together shall be deemed to be one and the same instrument.

hereto or any other person or entity.

                  14.9 Mutual Drafting.  This Agreement is the mutual product of
the parties  hereto,  and each  provision  hereof has been subject to the mutual
consultation, negotiation and agreement of each of the parties, and shall not be
construed for or against any party hereto.

party further  represents that it is being  independently  advised as to the tax
consequences  of the  transactions  contemplated  by this  Agreement  and is not

tax consequences.

                  14.11    Specific Performance; Remedies.

                  (a) Seller  acknowledges  that  Purchaser  will be irreparably

Seller of the  covenants  or  agreements  contained in Sections 7.2 (a) and (c),
7.3, 7.6, 7.9, 7.12, 7.15 and 7.16 of this


                                     - 40 -

Agreement.  It is  accordingly  agreed that,  in addition to any other  remedies
which may be  available  upon the breach of any such  covenants  or  agreements,
Purchaser shall have the right to obtain  injunctive relief to restrain a breach
or threatened  breach of, or otherwise to obtain specific  performance of, these
covenants and agreements of the Seller.

                  (b)  Purchaser  acknowledges  that Seller will be  irreparably
harmed and that there will be no  adequate  remedy at law for any  violation  by
Purchaser of the covenants or agreements contained in Sections 7.15 and 7.17 and
Article 8 of this Agreement.  It is accordingly  agreed that, in addition to any
other  remedies  which may be available upon the breach of any such covenants or
agreements,  Seller shall have the right to obtain injunctive relief to restrain
a breach or threatened  breach of, or otherwise to obtain  specific  performance
of, these covenants and agreements of Purchaser.


                  14.12 Right of First Refusal; Transfer of Securities.

                  (a)  For  two (2)  years  from  the  Closing  Date,  Purchaser
covenants not to transfer the Shares and the Conversion Shares to any Person who
engages  in the  construction  business  as a general  contractor,  construction
manager or engineer  constructor  competitive  with the business of Seller (such
share transfer, a "Competitor Transfer").

                  (b) After  two (2)  years  from the  Closing  Date,  Purchaser
grants to Seller the right of first refusal,  each time that Purchaser  plans to
effect a Competitor Transfer. In each such event,  Purchaser shall notify Seller
of such  proposed  Competitor  Transfer  and  provide  Seller with the number of
Shares  and/or  Conversion  Shares  to be  transferred  and the  price and terms
(including  tax  treatment)  of  the  proposed  Share  and/or  Conversion  Share
transfer.  Seller shall have the right in its sole  discretion,  for a period of
fifteen  (15) days  after  receipt  of the notice  from  Purchaser,  to elect by
written  notice to  Purchaser to purchase all Shares  and/or  Conversion  Shares
subject to the  proposed  Competitor  Transfer on the same terms and  conditions
offered by such Competitor  ("Purchase  Notice").  Seller shall have thirty (30)
days from the date such Purchaser Notice is delivered to Purchaser to effect the
purchase.  In the event that Seller does not send the Purchase Notice within the
fifteen (15) day period or does not purchase the Shares and/or Conversion Shares
within  thirty (30) days after the  Purchase  Notice is  delivered,  Purchaser's
right of first refusal to the proposed Competitor Transfer shall terminate.

                  (c) The  Seller's  decision  as to  whether to send a Purchase
Notice  and/or  effect the  purchase  of the  Shares  and/or  Conversion  Shares
encompassed  by the Purchase  Notice shall not require  action of the  Executive
Committee nor shall the Designated  Directors (as defined in the  Certificate of
Vote of Directors) vote on this matter.

<PAGE>



                  (d) The  rights of first  refusal  set  forth in this  Section
shall terminate at the earlier of the fourth  anniversary of the Closing Date or
at such time as  Purchaser  holds  less than 50% of the Shares  acquired  on the
Closing Date  (including any  Conversion  Shares into which any such Shares have
been converted).

                  (e)  For  two (2)  years  from  the  Closing  Date,  Purchaser
covenants  not to sell or otherwise  transfer,  or permit anyone else to sell or
otherwise  transfer,  any interest in Purchaser to any Person who engages in the
construction business as a general contractor,  construction manager or engineer
constructor competitive with the business of Seller.

                  4.  Section  3.5 is amended and  restated  in its  entirety as
follows:

                  3.5 Rights  Agreement.  The Rights  Agreement shall be in full
force and effect and not have been amended,  modified or supplemented on orafter
the date of this Agreement other than as provided in the following sentence. The
Board of Directors of the Seller shall have (a) amended or waived  provisions of
the Rights  Agreement  such that neither the  execution nor the delivery of this
Agreement and the other  Transaction  Documents nor the fulfillment of the terms
of this  Agreement by the Seller nor the issuance of shares of Conversion  Stock
as herein  contemplated  will cause  there to be a Stock  Acquisition  Date or a
Distribution  Date (as those  terms are  defined in the Rights  Agreement),  (b)
amended the provisions of the Rights  Agreement to provide that Purchaser  shall
not be deemed to be an  Adverse  Person  (as that term is  defined in the Rights
Agreement), and (c) amended the provisions of the Rights Agreement (i) to lower,
for at least  thirty-eight  months  following  the Closing,  the  threshold  for

issued and  outstanding  Common Stock to  beneficial  ownership  10% of the then
issued and outstanding  Common Stock, and (ii) to change the Initial  Expiration
Date to a date that is at least thirty-eight months following the Closing.

                  5.  Section  3.7  is  amended  by  striking  the  words  "upon
ratification  within  one year  hereof of the sale of Shares  described  in this
Agreement by shareholders of Seller (including holders of the Shares)".

                  6.  Article  III is  amended  by adding  the  following  after
Section 3.14:

                  3.15 Shareholder  Meeting Matters.  Seller shall have held the

Shareholder Meeting Matters by the requisite votes required by applicable law.

                  3.16 Ronald  Tutor.  Ronald Tutor shall not be prevented  from
serving  on the Board of  Directors  of Seller or from  acting  chief  operating
officer  of  Seller  by (a)  any  action  of a  state  or  federal  governmental
authority,  or (b) his death or  disability.  No state or  federal  governmental
authority  shall have  threatened to file a lawsuit or institute  administrative
action (x) to prevent Ronald Tutor from so serving, (y) to limit his role as

                                      - 2 -

<PAGE>



officer or  director  of Seller,  or (z) to seek  civil or  criminal  damages or
penalties  against  any of the  parties  hereto  or Tutor  should he serve as an
officer or director of Seller,  and, in the reasonable  judgment of RCBA,  there
shall not be a material risk of such a suit or action. Seller shall have entered
into a management  agreement with Tutor-Saliba  Corporation in substantially the
form of Exhibit 3.16 hereto, with such changes as shall be required by any state
or federal  governmental  authority (which changes are reasonably  acceptable to
Seller, Tutor-Saliba Corporation, and RCBA), and such agreement shall be in full
force and effect.

                  3.17 Conflict of Interest.  RCBA has previously advised Seller
of its insistence that RCBA, PB, and Seller avoid any and all possible  conflict
of interest  issue  arising out of PB's  proposed  investment  in Seller and the
relationship of a principal of RCBA to a United States  Senator.  There fore, it
is a  condition  to Closing  (a) that the Senate  Ethics  Committee  and regular
counsel  for the  Senator  on such  matters  shall  each have  given an  opinion
concerning  RCBA's  involvement with Seller that, in the reason able judgment of
RCBA,  does not require the imposition of material  restrictions on the business
of Seller or upon the  ability  of the  Senator to vote on matters of concern to
her  constituents,  and (b) that RCBA be assured by the  Executive  Committee of
Seller's  Board of Directors  that it will cause Seller not to bid for a project
when and if advised of RCBA's view that such bid could create a significant risk
of  exposing  Seller,  RCBA,  PB,  and/or the  Senator to a conflict of interest
problem .

                  7. Article IV is amended by adding the following after Section
4.9:

                  4.10 Shareholder  Meeting Matters.  Seller shall have held the
Shareholder  Meeting and the  shareholders  of Seller  shall have  approved  the
Shareholder Meeting Matters by the requisite votes required by applicable law.

                  8.  Section  5.22 is amended and  restated in its  entirety as
follows:

                  5.22 No Material  Adverse Change.  Since the latest date as of
which  information  with  respect  to the  following  items  is given in the SEC
Documents  filed  prior  to  July  24,  1996  and  except  as  contained  in the

by RCBA); or

                  (e) any material  increase in the compensation,  bonus,  sales
commissions or fee arrangements payable or to become payable by Seller to any of
its officers directors,  stockholders,  employees, consultants or agents, except
for  ordinary  and  customary  bonuses and salary  increased  for  employees  in
accordance with past practice; or

                  (f) any work interruptions,  labor grievances or claims filed,
or any  similar  event  or  condition  of any  character,  materially  adversely
affecting the business or future prospects of Seller; or

transfer,  any material assets property or rights of Seller to any person (other

                  (i)  any  plan,   agreement   or   arrangement   granting  any

certain  letter  agreement  dated as of  November  7, 1996  between  Seller  and

Seller acknowledges that RCBA has incurred  significant expenses in the interest
of  expediting  and  completing  the  transaction,  and has  also  incurred  due
diligence  expenses  that will benefit  Seller on an ongoing  basis;  therefore,

EXHIBIT 1.32                                                       
                                                                        

                          REGISTRATION RIGHTS AGREEMENT

                  This  REGISTRATION  RIGHTS  AGREEMENT  (this  "Agreement")  is
entered  into as of  September  __, 1996,  by and among  PERINI  CORPORATION,  a
Massachusetts  corporation (the  "Corporation"),  and PB CAPITAL PARTNERS,  INC.
("PB").  Terms not  defined  herein  shall have the  meanings  given them in the
Purchase Agreement (defined below).

                                    RECITALS

                  WHEREAS, the Corporation and PB have entered into that certain
Stock  Purchase  Agreement,  dated  July __,  1996 (the  "Purchase  Agreement"),
pursuant to which,  in pertinent  part,  PB purchased and the  Corporation  sold
certain  securities  of the  Corporation  (the "Series B Cumulative  Convertible
Preferred Stock");

                  WHEREAS,  pursuant to the terms of the Purchase Agreement, the
Series B Cumulative  Convertible  Preferred Stock is convertible  into shares of
the Corporation's common stock (the "Common Stock"); and

                  WHEREAS,  as a result of the  foregoing  and  pursuant  to the
terms of the  Purchase  Agreement,  the  Corporation  has agreed to register the
shares of Common Stock  received by PB pursuant to the terms and  conditions set
forth herein.

                                   AGREEMENTS

                  NOW THEREFORE,  in consideration of the foregoing recitals and
other good and valuable consideration,  the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

                  1. In the event the Corporation files one or more registration
statements  (each, a  "Registration  Statement")  for its Common Stock under the
Securities  Act of 1933, as amended (the "Act") for a purpose and on a form that
would permit the  registration  of the Conversion  Shares after such time as the
shareholders  of the  Corporation  have  ratified  the  issuance of the Series B
Cumulative  Convertible  Preferred  Stock to PB and approved the issuance of the
Common Stock upon  conversion of the Series B Cumulative  Convertible  Preferred
Stock, the Corporation shall afford PB and any permitted  successors and assigns
under the Purchase  Agreement (the  "Purchasers")  a right to participate in the
offering under such registration  statement;  provided,  however, that where the
offeror  is  the  Corporation,  such  piggy-back  right  shall  subject  to  the
reasonable   judgment  of  the  lead  underwriter  of  the  offering  that  such
participation  will not  impair  the  ability  of the  Corporation  to raise the
capital being sought by it; provided further, however, that the Purchasers shall
participate  in any such  offering on a basis at least as favorable as any other
offeror (other than the Corporation). The Corporation shall use its best efforts
to keep such Registration  Statements  continuously  useable and effective until
such time as such  underwriter has completed the  distribution of all securities
of the Purchasers registered thereunder (the "Section 1 Effective Period").

                  2. In the event that (a) no  Registration  Statement under the
Act has been filed under Section 1 hereof by the later of (i) September __, 1998
or (ii) such time as the  shareholders  of the  Corporation  have  ratified  the
issuance of the Series B Cumulative  Convertible  Preferred  Stock to PB, or (b)
such a  Registration  Statement  was  filed  but  Purchasers  continue  to  hold
unregistered  Conversion  Shares or Series B  Cumulative  Convertible  Preferred
Stock,  then, as promptly as practicable  upon request from  Purchasers  holding
unregistered  Conversion  Shares  (not  previous  ly sold under Rule 144 without
registration) and Series B Cumulative  Convertible  Preferred Stock representing
at least fifty percent (50%) of the voting power of the outstanding unregistered
Conversion  Shares  and Series B  Cumulative  Convertible  Preferred  Stock (the
"Requisite   Purchasers")   (provided  that  the  requesting   Purchasers   hold
unregistered  Conversion  Shares  (not  previously  sold under Rule 144  without
registration)  and  Series B  Cumulative  Convertible  Preferred  Stock with the
voting power of at least ______ shares of Common Stock),  the Corporation  shall
file  and use its best  efforts  to cause to be  declared  effective  a  "shelf"
Registration  Statement on any appropriate form pursuant to Rule 415 (or similar
rule that may be adopted by the Securities and Exchange  Commission (the "SEC"))
under the Act for all such unregistered  Common Stock held by the Purchasers and
any Common Stock into which the Series B Cumulative  Convertible Preferred Stock
held by the Purchasers may be converted (the  "Registrable  Securities"),  which
form shall be available for the sale of the Registrable Securities in accordance
with the intended method or methods of distribution thereof. Except as set forth
below,  the Corporation  agrees to use its best efforts to keep the Registration
Statement continuously effective and usable for resale of Registrable Securities
until such time as all the Registrable Securities have been sold pursuant to the
Registration Statement (the "Section 2 Effective Period"). In the event that the
Corporation  shall fail to maintain an effective  shelf  registration  until the
Purchasers  have  sold  all  of  their  Registrable  Securities,  the  Requisite
Purchasers  shall have the right to demand that the Corporation file and use its
best  efforts to cause to be declared  effective a second  "shelf"  Registration
Statement on any appropriate form pursuant to Rule 415 (or similar rule that may
be adopted by the Securities and Exchange  Commission (the "SEC")) under the Act
for any and all remaining Registrable Securities.

                  3. In any such  Registration  Statement  in  which  Purchasers
participate, the following provisions shall apply:

                  (a) The Corporation  shall pay all reasonable costs (excluding
registration fees,  transfer taxes, if any, and fees and expenses of Purchasers'
counsel  and  any  underwriting  or  selling  commissions),  fees  and  expenses
including,  without  limitation,  the  Corporation's  legal and accounting  fees
(including  the costs and  expenses of any special  audit or other  procedures),
printing expenses and blue sky fees and expenses.

                  (b) The Corporation  will take all necessary  action which may
be  required  in  qualifying  or  registering  the  securities  included  in the
registration  statement  for offering and sale under the  securities or blue sky
laws of such states as reasonably are requested by Purchasers


                                      - 2 -


<PAGE>



pursuant to such registration statement and in no event shall the Corporation be
required to effect such  qualification or registration if such act would require
the Corporation to qualify as a foreign corporation or to file a general consent
to service of process in any  jurisdiction  where it is not now so  qualified or
required to file such a consent.

                  (c)  Upon  any  such  registration  becoming  effective,   the
Corporation shall use its best efforts to: (i) keep such registration  statement
current  until the  Purchasers  have sold the shares it had  registered to sell;
(ii) prepare and file with the SEC amendments and  post-effective  amendments to
the Registration Statement and such amendments and supplements to the prospectus
used in connection  therewith as may be necessary to maintain the  effectiveness
of such  registration  during the  Section 1  Effective  Period or the Section 2
Effective  Period,  as the case may be (the  "Effective  Period"),  or as may be
required  by  the  rules,   regulations  or   instructions   applicable  to  the
registration  form  utilized  by the  Corporation  or by the  Act or  rules  and
regulations thereunder for shelf registration or otherwise necessary to keep the
Registration  Statement  effective  for  the  Effective  Period  and  cause  the
prospectus as so  supplemented  to be filed  pursuant to Rule 424 under the Act,
and to  otherwise  comply with the  provisions  of the Act during the  Effective
Period; (iii) cause all the securities  registered pursuant to such registration
statement to be listed on each exchange or automated  quotation  system on which
the securities are then listed;  (iv) provide a transfer agent and registrar for
all stock registered  pursuant to such  registration  statement and CUSIP number
for all such  stock,  in each case not  later  than the  effective  date of such
registration;  and (v)  otherwise  use its  best  efforts  to  comply  with  all
applicable  rules and  regulations of the SEC;  provided,  however,  that before
filing the  Registration  Statement or a prospectus  contained  therein,  or any
amendments  or  supplements   thereto,  the  Corporation  will  furnish  to  the
Purchasers  and their  counsel for review and comment,  copies of all  documents
proposed to be filed.

                  (d) As  expeditiously  as possible  furnish to the  Purchasers
such  reasonable  numbers of copies of the  prospectus,  including a preliminary
prospectus,  in  conformity  with the  requirements  of the Act,  and such other
documents as the Purchasers  may  reasonably  request in order to facilitate the
public sale or other  disposition of the securities owned by the Purchasers.  If
the  Corporation  has delivered  preliminary or final  prospectuses to a selling
holder and after  having done so the  prospectus  must be amended to comply with
the  requirements of the Act, the Corporation  shall promptly notify the selling
holder and such holder shall cease making offers of the  securities  immediately
upon such  request  and to  return  all  prospectuses  to the  Corporation.  The
Corporation shall promptly provide the selling holder with revised  prospectuses
and, following receipt of the revised prospectuses,  the selling holder shall be
free to resume making offers of the securities.

                  (e) The  Corporation  shall  indemnify  and hold  harmless the
holder(s) of the  securities to be sold pursuant to any  registration  statement
and each person,  if any, who controls such holder within the meaning of Section
15 of the Act or Section 20(a) of the Securities

Exchange Act of 1934,  as amended  (the  "Exchange  Act"),  against and from all
loss, claim,  damage,  expense or liability  (including all expenses  reasonably
incurred in investigating,  preparing or defending against any claim whatsoever)
to which any of them may  become  subject  under the Act,  the  Exchange  Act or
otherwise,  arising  from such  registration  statement,  except such matters in
respect of which such holders are required to indemnify  the  Corporation  under
the next succeeding paragraph.

                  (f) Each  Purchaser,  as the holder of  securities  to be sold
pursuant to a registration  statement,  and its or their successors and assigns,
shall  indemnify and hold harmless the  Corporation,  its officers and directors
and each person,  if any, who  controls  the  Corporation  within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act, against and from all
loss, claim,  damage,  expense or liability  (including all expenses  reasonably
incurred in investigating,  preparing or defending against any claim whatsoever)
to which they may become  subject  under the Act, the Exchange Act or otherwise,
arising  from  information  furnished  by or on behalf of such holders or its or
their  successors  or  assigns,  for  specific  inclusion  in such  registration
statement.

                  (g) Any person entitled to indemnification  under this Section
will (i) give prompt written notice to the indemnifying  party of any claim with
respect to which it seeks  indemnification  and (ii) unless in such  indemnified
party's reasonable  judgment a conflict of interest between such indemnified and
indemnifying  parties  may  exist  with  respect  to  such  claim,  permit  such
indemnifying  party to assume the defense of such claim with counsel  reasonably
satisfactory  to  the  indemnified  party.  If  such  defense  is  assumed,  the
indemnifying  party will not be subject to any liability for any settlement made
by the  indemnified  party  without its consent  (but such  consent  will not be
unreasonably  withheld). An indemnifying party who is not entitled to, or elects
not to,  assume the defense of a claim will not be obligated to pay the fees and
expenses  of  more  than  one  counsel  for  all  parties  indemnified  by  such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any  indemnified  party  a  conflict  of  interest  may  exist  between  such
indemnified party and any other of such indemnified parties with respect to such
claim.

                  (h) If the  indemnification  provided for in this Section from
the  indemnifying  party is unavailable to an indemnified  party hereunder or is
insufficient to hold such  indemnified  party harmless in respect of any losses,
claims,  damages,  liabilities or expenses  referred to herein and to which this
Section  would  apply by its  terms,  then the  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 losses,  claims,  damages,
liabilities  or expenses in such  proportion  as is  appropriate  to reflect the
relative fault of the indemnifying  party and indemnified  parties in connection
with the actions or inactions  which resulted in such losses,  claims,  damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative fault of such indemnifying  party and indemnified  parties shall be
determined by


                                      - 4 -

reference to, among other things, whether any action in question,  including any
untrue or alleged  untrue  statement  of a material  fact or omission or alleged
omission to state a material  fact,  has been made by, or relates to information
supplied by, such indemnifying  party or indemnified  parties,  and the parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent  such  action.  The amount paid or payable by a party as a result of the
losses,  claims,  damages,  liabilities and expenses  referred to above shall be
deemed to include  any legal or other fees or  expenses  reasonably  incurred by
such party in connection with any investigation or proceeding.

                  (i) The  parties  hereto  agree  that it would not be just and
equitable if contribution pursuant to this paragraph were determined by pro rata
allocations or by any other method of allocation  which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No  person  guilty  of  fraudulent   misrepresentation   shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation. shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

                  (j) If  indemnification  is available under this Section,  the
indemnifying  parties shall indemnify each indemnified  party to the full extent
provided in  paragraphs  E and F without  regard to the  relative  fault of said
indemnifying  party or indemnified  party or any other  equitable  consideration
provided for in this Section.

                   Amendment to By-Laws of Perini Corporation


                  1. Section 3.3 of the By-Laws shall be amended and restated in
its entirety as follows:

                  "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:  (a) any borrowing or guarantee by the
corporation  exceeding  $15 million,  (b) except for issuances of stock or stock
options pursuant to the corporation's  incentive compensation plans or programs,
any  issu  ance of  stock  (whether  common  or  preferred,  whether  voting  or
non-voting,  whether  junior or senior to the  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
September __, 1996, (c) any strategic  alliance (other than a construction joint
venture) involving a capital commitment exceeding $5 million, (d) any asset sale
or lease  exceeding $5 million (other than equipment  dispositions in the normal
course of business);  (e) any  redemption  or amendment 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
prior  to  September  __,  1996  ('Rights'),  or  the  preferred  stock  of  the
Corporation  issuable upon the exercise of such Rights,  or any amendment of the
Rights  Agreement by and between the  Corporation and the First National Bank at
Boston,  dated as of September 23, 1988, as amended;  and (f) any termination of
or  amendment  to  the  management   agreement   between  the   Corporation  and
Tutor-Saliba Corporation;  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.
Notwith  standing  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


                                      - 1 -

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 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."

                  2.  Section 4.5 of the By-Laws  shall be amended by  replacing
the phrase  "subject to the  direction  of the  directors"  each time it appears
therein with "subject to the direction of the Executive Committee for so long as
it exists and thereafter subject to the direction of the directors."

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 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


                                      - 3 -


<PAGE>



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  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  Con
vertible  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
Cumula tive 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 Cumu lative  Convertible  Preferred  Stock.  Each fractional share of Series B
Cumulative  Convertible  Preferred Stock outstanding shall also be entitled to a
ratably propor tionate  amount of any other  distributions  made with respect to
each outstanding share of Series B Cumulative  Convertible  Preferred Stock, and
all such


                                      - 4 -


<PAGE>



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)).

                  (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 peri ods terminating on or prior to the date of payment of such
full cumulative divi dends. 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 contempora neously 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


                                      - 5 -


<PAGE>



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.

                  (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


                                      - 6 -


<PAGE>



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  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


                                      - 7 -


<PAGE>



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
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


                                      - 8 -


<PAGE>



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.

                  (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


                                      - 9 -


<PAGE>



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 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);

<PAGE>




                  (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 between the Corporation 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 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

                  (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 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 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  Cents ($9.68),  and shall be adjusted from time
to time after the Original Issue Date in accordance  with the provisions of this
Section 8.

                  (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:


                                     - 15 -


<PAGE>




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


                                     - 16 -


<PAGE>



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  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


                                     - 17 -


<PAGE>



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  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


                                     - 18 -


<PAGE>



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 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


                                     - 19 -


<PAGE>



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 "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


                                     - 20 -


<PAGE>



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
conclu  sive) 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

                  (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


                                     - 21 -


<PAGE>



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,  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 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.

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

become effective,  and the date, if any, as of which it is expected that holders

                  (iii) "Extraordinary Equity Payment" shall mean:

                  (1) the  declaration or payment on or after the Original Issue

<PAGE>



Cumulative  Convertible  Preferred Stock in accordance with the terms thereof as
in effect on the Original Issue Date;

                  (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

Stock and shall have paid in full such dividends in cash when due;

                  (2)  any  repurchases,   redemptions,   retirements  or  other

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

                  (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


                                     - 26 -


<PAGE>



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
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


                                     - 27 -

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.

                  (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


                                     - 28 -


<PAGE>



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
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 equal to (x) the
number of votes  possessed  by such  share  immediately  preceding  such  event,
multiplied by (y) the conversion price immediately preceding such event, divided
by (z) 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
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


                                     - 30 -


<PAGE>



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.

         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

complied  with,  all in  accordance  with  such  reasonable  regulations  as the

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

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.

                  (iii) In the event that the holders of the Series B Cumulative
Convertible Preferred Stock dispose of such stock or Conversion


                                     - 33 -


<PAGE>



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


                                     - 34 -


<PAGE>



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


                                     - 35 -


<PAGE>



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 than Common Stock
in an aggre gate 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  between
the  Corporation  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


                                     - 36 -

decreased,  then such court may make such change as shall be necessary to render
the provision in question effective and valid under applicable law.

         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

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

the representatives of PB designated in accordance with the Certificate of Vote,
and shall call such  Stockholders'  meetings as may be necessary or requested by

shares of the  Perini  Voting  Stock held by the  Stockholders  by reason of any
stock  dividend,  stock split,  consolidation  of shares,  reclassification,  or

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:

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

              $30,000,000  equity  investment in the Borrower in accordance with
              the Stock Purchase Agreement;

              Borrower  and its  Subsidiaries  and  that  each  of RCBA  and the
              Purchaser is fully satisfied with the results thereof;

                      (d)  November  1,  1996,  unless on or before  such date a
              proxy statement  soliciting  consents from the shareholders of the
              Borrower to the sale of shares of Series B Cumulative  Convertible
              Preferred  Stock to the  Purchaser  in  accordance  with the Stock

              3. Waiver of Certain  Events of Default.  Subject to clause (e) of
the definition of "Bridge  Termination  Date" as modified by paragraph 2 of this

Termination  Date,  the Banks and the Bridge Banks hereby waive (i) the Defaults

Bridge Credit Agreement exists.

              5. Effect of Amendments and Waivers. Except as expressly set forth
herein,  the  amendments  and waivers  contained  herein shall not constitute an
amendment or waiver of any term or condition of the Credit Agreement, the Bridge
Credit  Agreement  or any  other  Financing  Documents,  and all such  terms and
conditions  shall  remain in full force and effect and are hereby  ratified  and
confirmed in all respects.

              6.  Governing Law.  This Amendment shall be governed by and
construed in accordance with the laws of the State of New York.

              NOW, THEREFORE, the parties hereto agree as follows:

              1. Definitions;  References. Unless otherwise specifically defined
herein,  each term used herein which is defined in the Bridge  Credit  Agreement
shall have the meaning assigned to such term in the Bridge Credit Agreement,  as
the case may be. Each reference to "hereof", "hereunder",  "herein" and "hereby"
and each other similar reference and each reference to "this Agreement" and each
other similar reference  contained in the Bridge Credit Agreement shall from and

Default  under the  Credit  Agreement  and no Default  under the  Bridge  Credit
Agreement exists.

              4. Effect of Amendment.  Except as expressly set forth herein, the
amendments  and waivers  contained  herein shall not  constitute an amendment or
waiver of any term or  condition  of the Credit  Agreement,  the  Bridge  Credit
Agreement or any other  Financing  Documents,  and all such terms and conditions
shall remain in full force and effect and are hereby  ratified and  confirmed in
all respects.

              5.  Governing Law.  This Amendment shall be governed by and
construed in accordance with the laws of the State of New York.

              6.  Counterparts.  This Amendment may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

              7. Effectiveness.  This Amendment shall become effective as of the
date hereof when the Agent shall have received duly executed counterparts hereof
signed by the Borrower,  each of the Bridge Banks and each Subsidiary  Guarantor
(or, in the case of any party as to which an executed counterpart shall not have
been received, the Agent shall have received telegraphic, telex or other written
confirmation  from  such  party of  execution  of a  counterpart  hereof by such
party).


              IN WITNESS WHEREOF,  the parties hereto have caused this Amendment
to be duly executed by their respective authorized officers as of the date first
above written.

entirety as follows:

                           SECTION 2.01.  The Bridge Loans.

                           (a) On the  Amendment  No.  8  Effective  Date,  each
         Bridge  Bank with a Bridge Term  Commitment  severally  agrees,  on the
         terms and conditions set forth in this Agreement, to make a single loan
         to  the  Borrower  in a  principal  amount  equal  to its  Bridge  Term
         Commitment  on such date (each such loan, a "Bridge  Term  Loan").  The
         Bridge Term Loans are not  revolving  in nature and any amounts of such
         Bridge Term Loans repaid or prepaid may not be reborrowed.

         pursuant to Section  2.01 of this  Agreement  as in effect prior to the
         Amendment  No. 8  Effective  Date.  From  time to time on and after the
         Amendment  No. 8  Effective  Date but prior to the  Bridge  Termination
         Date,  each Bridge Bank severally  agrees,  on the terms and conditions

         Agreement  prior to the  Amendment  No. 8  Effective  Date,  a  "Bridge
         Revolving Loan") in amounts such that the outstanding  principal amount
         of such Bridge Bank's Bridge  Revolving Loans shall not exceed,  in the
         aggregate at any time, the amount of its Bridge  Revolving  Commitment.
         Each  Bridge  Borrowing  under  this  Section  2.01(b)  shall  be in an
         aggregate  principal  amount of $500,000 or any larger multiple thereof
         (except that any such Bridge  Borrowing may be in the aggregate  amount
         of the unused Bridge  Revolving  Commitments)  and shall be made by the
         several Bridge Banks ratably in proportion to their  respective  Bridge
         Revolving  Commitments.  Within the foregoing limits,  the Borrower may
         borrow under this Section 2.01(b), repay, or to the extent permitted by
         Section  2.10 or  Section  2.11,  prepay  Bridge  Revolving  Loans  and
         reborrow  under  this  Section  2.01(b) at any time prior to the Bridge
         Termination Date.

2.05 of the Bridge Credit Agreement is amended and restated in its entirety as
follows:

                           SECTION 2.05.  Interest Rates. Each Bridge Loan shall
         bear interest on the outstanding principal amount thereof, for each day
         from the date such Bridge Loan is made until it becomes  due, at a rate
         per annum equal to the sum of the Base Rate for such day plus (i) 4% in
         the case of any Bridge Term Loan,  or (ii) 2% in the case of any Bridge
         Revolving  Loan.  Interest on all Bridge  Loans shall be payable on the
         last Business Day of each month and on the Bridge Termination Date. Any
         overdue  principal  of or  interest  on  any  Bridge  Loan  shall  bear
         interest,  payable  on  demand,  for each day until  paid at a rate per
         annum equal to the sum of 2% plus the rate otherwise applicable to such
         Bridge Loan for such day.


                  SECTION 5. Amendments to Provisions for Mandatory  Termination
or Reduction of Bridge  Commitments.  Subsections (c) and (d) of Section 2.10 of
the Bridge  Credit  Agreement  are  amended and  restated  in their  entirety as

         to Section  2.10(b)  shall be applied  first to reduce the Bridge  Term
         Commitments  and,  when the  Bridge  Term  Commitments  shall have been
         reduced to zero, then to reduce the Bridge  Revolving  Commitments.  On
         each day on which  any  Bridge  Commitments  are  reduced  pursuant  to
         Section 2.10(b), the Borrower shall repay such principal amount of each
         Bridge Bank's  outstanding Bridge Loans (together with accrued interest
         thereon)  as may be  necessary  so that after such  repayment:  (i) the
         aggregate  unpaid  principal  amount of such Bridge  Bank's Bridge Term
         Loans shall not exceed the amount of its Bridge Term  Commitment  after
         giving effect to such reduction and (ii) the aggregate unpaid principal
         amount of such Bridge  Bank's Bridge  Revolving  Loans shall not exceed
         the amount of its Bridge  Revolving  Commitment  after giving effect to
         such reduction.

                           (d) Any  reduction  of the  Bridge  Term  Commitments
         pursuant  to this  Section  2.10  shall be applied to reduce the Bridge
         Term Commitments pro rata among the Bridge Banks in proportion to their
         respective  Bridge Term  Commitments at that time, and any reduction of
         the Bridge Revolving Commitments pursuant to this Section 2.10 shall be
         applied to reduce the Bridge  Revolving  Commitments pro rata among the
         Bridge  Banks  in  proportion  to  their  respective  Bridge  Revolving
         Commitments at that time.
