Report of Independent Public Accountants



To the Stockholders of Perini Corporation:

We have audited the  accompanying  combined  balance sheet of the joint ventures
identified  in  Note  1 as of  December  31,  1997,  and  the  related  combined
statements of income,  venturers' equity and cash flows for the year then ended.
These  financial  statements  are the  responsibility  of the  joint  venturers'
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of the joint ventures  identified
in Note 1 as of December 31, 1997, and the results of their operations and their
cash  flows  for the year  then  ended in  conformity  with  generally  accepted
accounting principles.

                               Perini Corporation
      Notes to Combined Financial Statements of Significant Joint Ventures
                      For the Year Ended December 31, 1997


[1]  Basis of Combination

Perini Corporation (the "Company"),  in the normal conduct of its business,  has
entered into  partnership  arrangements,  referred to as "joint  ventures",  for
certain construction  projects in order to share risk, working capital,  bonding
and  other  financial  requirements,  and in  some  instances,  to  obtain  more
extensive  knowledge  of a new  local  construction  market  or  certain  unique
construction  expertise  required.  Each of the joint  venture  participants  is
usually committed to supply a predetermined  percentage of capital, as required,
and to share in a predetermined percentage of the income or loss of the project.
These joint  ventures  are  temporary  in nature,  generally  from three to five
years, since they are formed to bid on a specific project,  execute the work, if
awarded  the  contract,  and are  liquidated  at the end of the  project.  While
control over the actual construction work performed is normally delegated to the
designated  joint  venture  sponsor,  usually the  partner  with a 50% or higher
percentage interest in the project,  the overall management of the joint venture
resides with a Management  Committee that requires unanimous approval of certain
key  operational  and financial  matters such as the amount of the original bid,
ability to borrow  funds,  incur  debt,  guarantees  and lease  commitments  and
investment policy regarding venture funds. In addition, the Management Committee
requires  unanimous  approval over terms of sale of venture  assets,  settlement
guidelines  related to  contract  claims and any  transaction  between the joint
venture and any of its partners.

In  accordance  with Rule 3-09 of  Regulation  S-X,  the Company  has  presented
combined  financial  statements of joint  ventures  considered to be significant
under the test,  because the  Company  believes  that  reporting  the  financial
results of any one joint venture by itself would not be significant to users and
could be detrimental to the Company when negotiating  unapproved contract change
orders  and  claims  with the  owner of the  project  or could  unfairly  assist
competitors when bidding against the Company on similar contracts in the future.
The following  joint ventures have been combined in the  accompanying  financial
statements:

[2]  Significant Accounting Policies

[a]  Long-Term Contracts
Profits from construction  joint venture  contracts are generally  recognized by
applying  percentages of completion for each year to the total estimated profits
for the respective  contracts.  The  percentages of completion are determined by
relating the actual cost of the work performed to date to the current  estimated
total  cost  of the  respective  contracts.  When  the  estimate  on a  contract
indicates  a loss,  the  ventures'  policy is to record  the  entire  loss.  The
cumulative  effect of revisions in estimates of total cost or revenue during the
course of the work is reflected in the accounting period in which the facts that
caused the revision become known.  An amount equal to the costs  attributable to
unapproved  change orders and claims is included in the total estimated  revenue
when realization is probable. Profit from unapproved change orders and claims is
recorded in the year such amounts are resolved.

In  accordance  with normal  practice in the  construction  industry,  the joint
ventures  include in current assets and current  liabilities  amounts related to
construction  contracts  realizable  and payable  over a period in excess of one
year.  Unbilled  work  represents  the  excess of  contract  costs  and  profits
recognized  to date on the  percentage  of  completion  accounting  method  over
billings to date on certain contracts.  Deferred contract revenue represents the
excess  of  billings  to date  over the  amount of  contract  costs and  profits
recognized  to date on the  percentage of  completion  accounting  method on the
remaining contracts.

[b]  Income Taxes
The joint  ventures  have not  recorded  any  provision  for income taxes in the
accompanying  financial statements as such liabilities are the responsibility of
the joint venture partners.

[c]  Use of Estimates
The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent assets and liabilities as of the date of the financial statements and
the reported amounts of revenues and expenses during the reporting  period.  The
most significant estimates with regard to the accompanying  financial statements
related to the estimating of final  construction  contract  profit in accordance
with accounting for long-term contracts (see Note 2[a]) and estimating potential
liabilities in conjunction with certain commitments and

                                       6




contingencies,  as  discussed  in Note  3.  Actual  results  could  differ  from
management's estimates and assumptions.

[d]  Fair Value of Financial Instruments
The joint ventures'  financial  instruments  consist  primarily of cash and cash
equivalents,   contract  accounts  receivable,   accounts  payable  and  accrued
expenses.  The carrying amount of these financial instruments  approximates fair
value due to their short-term nature.

[e]  Property and Equipment
Property  and  equipment  are  recorded  at cost and are  depreciated  using the
straight-line method over the estimated remaining life of the contract.

[f]  Cash and Cash Equivalents
Cash equivalents  include  short-term,  highly liquid  investments with original
maturities of three months or less.

[3]  Contingencies and Commitments

Certain joint  ventures  have  noncancellable  office and equipment  leases with
varying expiration dates through March 31, 2000. The following is a schedule, by
year, of future minimum rental payments required under all operating leases that
have initial or remaining noncancellable lease terms as of December 31, 1997:

                              Lease
       Year                Commitments
- ------------------      ------------------
       1998               $      1,217,062
       1999                      1,052,263
       2000                        128,441
                        ------------------
                          $      2,397,766
                        ==================

Rent expense  included in contract costs amounted to $680,846 for the year ended
December 31, 1997.

During 1997, a joint venture, in which the Company is a 50% participant, entered
into a $5  million  line of  credit,  secured  by the joint  venture's  accounts
receivable.  The line of  credit  is  available  for the  duration  of the joint
venture and is guaranteed by the Company on a joint and several basis, and as of
December 31, 1997, no amounts were outstanding under the line.

Contingent  liabilities  include  liability of contractors  for  performance and
completion  of joint  venture  construction  contracts.  In addition,  the joint
ventures are defendants in various lawsuits, arbitration and alternative dispute
resolution  ("ADR")  proceedings.  In the opinion of  management  of the various
joint  ventures,  the resolution of these  proceedings  will not have a material
effect on the results of  operations  or financial  condition as reported in the
accompanying combined financial statements.

[5]  Employee Benefit Plans

The  combined  joint  ventures  contribute  to  various   multi-employer   union
retirement  plans  under  collective   bargaining   agreements,   which  provide
retirement  benefits for  substantially  all of its union employees.  The Multi-
employer   Pension  Plan  Amendments  Act  of  1980  defines  certain   employer
obligations under multi-employer  plans.  Information regarding union retirement
plans are not  available  from plan  administrators  to enable  the  Company  to
determine its share of unfunded vested liabilities.

Supervisory   personnel  are  generally   covered  under  the  sponsoring  joint
venturer's plan.
