prescribed  by the PBGC for purposes of Section 4044 of ERISA,  exceeds (ii) the
fair market value of all Plan assets allocable to such  liabilities  under Title
IV of ERISA (excluding any accrued but unpaid contributions),  all determined as
of the then most  recent  valuation  date for such Plan,  but only to the extent
that such excess represents a potential liability of a member of the ERISA Group
to the PBGC or any other Person under Title IV of ERISA.

                  "Usage"  means,   at  any  date,  the  sum  of  the  aggregate
outstanding principal amount of the Bridge Loans at such date plus the aggregate
amount of Bridge Letter of Credit  Liabilities  at such date with respect to all
Bridge Letters of Credit.

                  "Wholly-Owned  Consolidated Subsidiary" means any Consolidated
Subsidiary of the Borrower all of the shares of capital stock or other ownership
interests  of  which  (except  directors'  qualifying  shares)  are at the  time
directly or indirectly owned by the Borrower.

                  SECTION  1.02.  Accounting  Terms and  Determinations.  Unless
otherwise   specified  herein,   all  accounting  terms  used  herein  shall  be
interpreted,  all  accounting  determinations  hereunder  shall be made, and all
financial  statements  required to be delivered  hereunder  shall be prepared in
accordance with generally accepted accounting  principles as in effect from time
to time,  applied on a basis consistent  (except for changes concurred in by the
Borrower's   independent  public  accountants)  with  the  most  recent  audited
consolidated   financial   statements  of  the  Borrower  and  its  Consolidated
Subsidiaries delivered to the Bridge Banks.


                                   ARTICLE II
                                  THE CREDITS

                  SECTION 2.01. The Bridge Loans. From time to time prior to the
Bridge  Termination  Date, each Bridge Bank severally  agrees,  on the terms and
conditions  set forth in this  Agreement,  to lend to the Borrower  from time to
time  amounts not to exceed in the  aggregate  at any one time  outstanding  the
amount of its Bridge Loan  Commitment.  Each Bridge Borrowing under this Section
shall be in an aggregate  principal  amount of $1,000,000 or any larger multiple
of $500,000  (except  that any such  Bridge  Borrowing  may be in the  aggregate
amount of the  unused  Bridge  Commitments)  and shall be made from the  several
Bridge Banks  ratably in  proportion  to their  respective  Bridge  Commitments.
Within the foregoing limits, the Borrower may borrow under this Section,  repay,
or to the extent permitted by Section 2.10 or Section 2.11,  prepay Bridge Loans
and  reborrow  at any time  prior to the  Bridge  Termination  Date  under  this
Section.

                  SECTION  2.02.  Method of Bridge  Borrowing.  (a) The Borrower
shall  give the Agent  notice (a "Notice  of Bridge  Borrowing")  not later than
11:30 A.M. (New York City time) on the date of each Bridge Borrowing  specifying
the date (which shall be a Business Day) and amount of such Bridge Borrowing.

                  (b) Upon  receipt of a Notice of Bridge  Borrowing,  the Agent
shall  promptly  notify  each Bridge  Bank of the  contents  thereof and of such
Bridge Bank's  ratable share of such Bridge  Borrowing and such Notice of Bridge
Borrowing shall not thereafter be revocable by the Borrower.

                  (c) Not later than 1:30 P.M.  (New York City time) on the date
of each  Bridge  Borrowing,  each  Bridge  Bank  shall  (except as  provided  in
subsection  (d) of this Section) make available its ratable share of such Bridge
Borrowing,  in Federal or other funds immediately available in New York City, to
the  Agent  at its  address  referred  to in  Section  8.01.  Unless  the  Agent
determines that any applicable  condition  specified in Article III has not been
satisfied,  the Agent  will make the funds so  received  from the  Bridge  Banks
available to the Borrower at the Agent's aforesaid address.

                  (d) If any Bridge Bank makes a new Bridge Loan  hereunder on a
day on which the Borrower is to repay all or any part of an  outstanding  Bridge
Loan from such Bridge Bank, such Bridge Bank shall apply the proceeds of its new
Bridge Loan to make such  repayment  and only an amount equal to the  difference
(if any) between the amount being  borrowed and the amount being repaid shall be
made available by such Bridge Bank to the Agent as provided in subsection (c) of
this  Section,  or remitted by the  Borrower to the Agent as provided in Section
2.12, as the case may be.

                  (e) Unless the Agent shall have received  notice from a Bridge
Bank  prior to noon (New York City  time) on the date of such  Bridge  Borrowing
that such Bridge Bank will not make  available  to the Agent such Bridge  Bank's
share of such Bridge  Borrowing,  the Agent may assume that such Bridge Bank has
made such share  available to the Agent on the date of such Bridge  Borrowing in
accordance with  subsections (c) and (d) of this Section 2.02 and the Agent may,
in reliance upon such assumption,  make available to the Borrower on such date a
corresponding  amount. If and to the extent that such Bridge Bank shall not have
so made such share  available  to the Agent,  such Bridge Bank and the  Borrower
severally  agree to repay to the Agent  forthwith  on demand such  corresponding
amount together with interest thereon, for each day from the date such amount is
made  available  to the  Borrower  until the date  such  amount is repaid to the
Agent, at (i) in the case of the Borrower,  a rate per annum equal to the higher
of the Federal Funds Rate and the interest rate applicable  thereto  pursuant to
Section 2.05 and (ii) in the case of such Bridge Bank,  the Federal  Funds Rate.
If such  Bridge Bank shall repay to the Agent such  corresponding  amount,  such
amount so repaid shall  constitute  such Bridge  Bank's  Bridge Loan included in
such Bridge Borrowing for purposes of this Agreement.

                  SECTION  2.03.  Bridge  Notes.  (a) The  Bridge  Loans of each
Bridge Bank shall be evidenced  by a single  Bridge Note payable to the order of
such Bridge Bank for the account of its Lending Office.

                  (b) Upon receipt of each Bridge Bank's Bridge Note pursuant to
Section  3.01(c),  the Agent shall forward such Bridge Note to such Bridge Bank.
Each Bridge Bank shall record the date,  amount and maturity of each Bridge Loan
made by it and the date and  amount of each  payment  of  principal  made by the
Borrower  with  respect  thereto,  and may,  if such  Bridge  Bank so  elects in
connection  with any transfer or enforcement of its Bridge Note,  endorse on the
schedule forming a part thereof appropriate  notations to evidence the foregoing
information  with  respect to each such Bridge Loan then  outstanding;  provided
that the failure of any Bridge Bank to make any such  recordation or endorsement
shall not affect the  obligations of the Borrower  hereunder or under the Bridge
Notes. Each Bridge Bank is hereby  irrevocably  authorized by the Borrower so to
endorse  its Bridge  Note and to attach to and make a part of its Bridge  Note a
continuation of any such schedule as and when required.

                  SECTION  2.04.  Maturity  of Bridge  Loans.  Each  Bridge Loan
included in any Bridge Borrowing shall mature,  and the principal amount thereof
shall be due and payable,  on the last day of the Interest Period  applicable to
such Bridge Borrowing.

                  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 2% plus the Base Rate for such day.  Such  interest  shall be payable for
each  Interest  Period on the last day  thereof.  Any  overdue  principal  of or
interest on any Base Rate 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 Bridge Loans for such day.

                  SECTION 2.06.  Bridge  Commitment Fees. The Borrower shall pay
to the Agent for the account of each Bridge Bank a commitment fee at the rate of
0.6% per annum on the daily average  unused portion of such Bridge Bank's Bridge
Commitments.  Such  commitment  fees shall accrue from and  including the Bridge
Effective Date to but excluding the Bridge  Termination  Date.  Such  commitment
fees  shall be payable on the last day of each  fiscal  quarter of the  Borrower
prior to the Bridge Termination Date and on the Bridge Termination Date. SECTION
2.07.  Participation Fee. The Borrower shall pay to the Agent for the account of
each Bridge Bank on the Bridge  Effective Date a participation  fee in an amount
equal to 2.0% of such Bridge Bank's Bridge Commitment.

                  SECTION 2.08.  Agency Fee. The Borrower shall pay to the Agent
as compensation  for its services  hereunder and under the Collateral  Documents
agency fees payable in the amounts and at the times  heretofore  agreed  between
the Borrower and the Agent.

                  SECTION  2.09.  Optional  Termination  or  Reduction of Bridge
Commitments.  The  Borrower  may,  upon 3  Business  Days'  notice to the Agent,
terminate at any time, or  proportionately  permanently reduce from time to time
by an aggregate  amount of $1,000,000 or any larger multiple of $1,000,000,  the
unused  portions  of the  Bridge  Commitments.  If the  Bridge  Commitments  are
terminated in their  entirety,  all accrued  commitment fees shall be payable on
the effective date of such termination.

                  SECTION  2.10.  Mandatory  Termination  or Reduction of Bridge
Commitments.   (a)  The  Bridge   Commitments  shall  terminate  on  the  Bridge
Termination  Date, and any Bridge Loans then outstanding  (together with accrued
interest thereon) shall be due and payable on such date.

                  (b) The  Bridge  Commitments  of all  Bridge  Banks  shall  be
permanently, automatically and ratably reduced:

                  (i) immediately upon receipt by the Borrower or any Subsidiary
         of the proceeds from the collection,  sale or other  disposition of any
         Collateral   (excluding   (A)  payments  in  the  ordinary   course  on
         construction  contracts,   (B)  operating  receipts  from  Real  Estate
         Investments,  (C)  liability  insurance  proceeds and (D) income of not
         more than $35,000 earned from Temporary Cash  Investments) by an amount
         equal to 100% of such  proceeds  net of all  out-of-pocket  costs,  all
         senior mortgage debt, fees,  commissions and other expenses  reasonably
         incurred in respect of such  collection,  sale or  disposition  and any
         taxes paid or  payable  (as  estimated  by a  financial  officer of the
         Borrower  in good  faith) in  respect  thereof;  provided  that no such
         reduction  shall be  required  unless and  until,  and then only to the
         extent that, the aggregate amount of such net proceeds  received by the
         Borrower  and  its  Subsidiaries  exceeds,  in the  case  of an item of
         Collateral  specified  in  Schedule  VII  hereto,  the amount set forth
         opposite such item or, in the case of other  Collateral,  $2,000,000 in
         the aggregate for all such other Collateral; and

                  (ii) by $15,000,000  upon the completion of an issuance by the
         Borrower of convertible preferred stock or other equity issue; provided
         that  in the  event  that  the  proceeds  of such  issuance  net of all
         out-of-pocket  expenses reasonably incurred in respect of such issuance
         and any taxes paid or payable (as  estimated by a financial  officer of
         the Borrower in good faith) in respect thereof exceeds $30,000,000, the
         aggregate  amount of the Commitments  shall be reduced by an amount not
         less  than  the  sum  of  $15,000,000  plus  50%  of  the  excess  over
         $30,000,000 of such proceeds.

                  (c) On each day on which  any  Bridge  Commitment  is  reduced
pursuant  to this  Section,  the  Borrower  shall  repay such  principal  amount
(together  with  accrued  interest  thereon) of each Bridge  Bank's  outstanding
Bridge  Loans as may be  necessary so that after such  repayment  the  aggregate
unpaid principal  amount of such Bridge Bank's Bridge Loans,  together with such
Bridge  Bank's  Percentage  of the  aggregate  amount of Bridge Letter of Credit
Liabilities,  does not exceed the amount of such Bridge Bank's Bridge Commitment
after giving effect to such reduction. In the event that the aggregate amount of
the Bridge Commitments is reduced to an amount less than the aggregate amount of
Bridge  Letter  of Credit  Liabilities  at such time in  respect  of all  Bridge
Letters of Credit,  the Borrower hereby agrees that it shall forthwith,  without
any demand or taking of any other  action by the  Required  Bridge  Banks or the
Agent,  pay to the Agent an amount in immediately  available  funds equal to the
difference  to be held as security for the Bridge  Letter of Credit  Liabilities
for the benefit of all Bridge Banks.

                  (d) Any  reduction  of the  Bridge  Commitments  described  in
clauses (a) and (b) above shall be applied to reduce the Bridge  Commitments pro
rata.

                  SECTION 2.11. Optional Prepayments. (a) The Borrower may, upon
notice to the  Agent  not later  than  11:30  A.M.  (New York City  time) on any
Business  Day,  prepay on such  Business  Day any Base Rate Bridge  Borrowing in
whole  at any  time,  or from  time to  time  in  part  in  amounts  aggregating
$1,000,000 or any larger multiple of $500,000, by paying the principal amount to
be prepaid  together with accrued  interest  thereon to the date of  prepayment.
Each such  optional  prepayment  shall be applied to prepay  ratably  the Bridge
Loans of the several Bridge Banks included in such Bridge Borrowing.

                  (b) Upon  receipt of a notice of  prepayment  pursuant to this
Section,  the Agent shall  promptly  notify  each  Bridge  Bank of the  contents
thereof and of such Bridge  Bank's  ratable  share of such  prepayment  and such
notice shall not thereafter be revocable by the Borrower.

                  SECTION  2.12.  General  Provisions  as to  Payments.  (a) The
Borrower  shall make each payment of  principal  of, and interest on, the Bridge
Loans and of fees  hereunder,  not later than 1:30 P.M.  (New York City time) on
the date when due, in Federal or other funds  immediately  available in New York
City, to the Agent at its address  referred to in Section  8.01.  The Agent will
promptly  distribute  to each Bridge Bank its ratable share of each such payment
received by the Agent for the account of the Bridge Banks.  Whenever any payment
of  principal  of, or interest on, the Bridge Loans or of fees shall be due on a
day which is not a Business Day, the date for payment  thereof shall be extended
to the next succeeding Business Day. If the date for any payment of principal is
extended by operation of law or otherwise, interest thereon shall be payable for
such extended time.

                  (b)  Unless  the Agent  shall have  received  notice  from the
Borrower  prior to the date on which  any  payment  is due to the  Bridge  Banks
hereunder  that the Borrower  will not make such payment in full,  the Agent may
assume that the Borrower has made such payment in full to the Agent on such date
and the Agent may, in reliance upon such assumption,  cause to be distributed to
each  Bridge  Bank on such due date an amount  equal to the amount then due such
Bridge Bank. If and to the extent that the Borrower  shall not have so made such
payment,  each  Bridge Bank shall  repay to the Agent  forthwith  on demand such
amount distributed to such Bridge Bank together with interest thereon,  for each
day from the date such amount is  distributed to such Bridge Bank until the date
such Bridge Bank repays such amount to the Agent, at the Federal Funds Rate.

                  SECTION 2.13. Computation of Interest and Fees. Interest based
on the Prime Rate shall be  computed  on the basis of a year of 365 days (or 366
days in a leap year) and paid for the actual  number of days elapsed  (including
the first day but excluding  the last day).  All other  interest and  commitment
fees  shall  be  computed  on the  basis  of a year of 360 days and paid for the
actual  number of days elapsed  (including  the first day but excluding the last
day).

                  SECTION 2.14.  Maximum Interest Rate. (a) Nothing contained in
this Agreement or the Bridge Notes shall require the Borrower to pay interest at
a rate  exceeding  the maximum rate  permitted by applicable  law.  Neither this
Section nor Section  8.08 is intended to limit the rate of interest  payable for
the account of any Bridge Bank to the maximum rate  permitted by the laws of the
State of New York if a higher rate is permitted with respect to such Bridge Bank
by supervening provisions of U.S. federal law.

                  (b) If the amount of  interest  payable for the account of any
Bridge Bank on any interest payment date in respect of the immediately preceding
interest computation period, computed pursuant to Section 2.05, would exceed the
maximum  amount  permitted by applicable  law to be charged by such Bridge Bank,
the amount of interest  payable for its account on such  interest  payment  date
shall be automatically reduced to such maximum permissible amount.

                  (c) If the amount of  interest  payable for the account of any
Bridge Bank in respect of any interest computation period is reduced pursuant to
clause (b) of this Section and the amount of interest payable for its account in
respect of any subsequent  interest  computation  period,  computed  pursuant to
Section 2.05,  would be less than the maximum amount permitted by applicable law
to be charged by such Bridge Bank,  then the amount of interest  payable for its
account in respect  of such  subsequent  interest  computation  period  shall be
automatically  increased to such maximum permissible amount; provided that at no
time shall the  aggregate  amount by which  interest paid for the account of any
Bridge Bank has been increased  pursuant to this clause (c) exceed the aggregate
amount by which  interest  paid for its account  has  theretofore  been  reduced
pursuant to clause (b) of this Section.

                  SECTION  2.15.  Bridge  Letters of Credit.  (a) Subject to the
terms and  conditions  hereof,  the  Bridge LC Bank  agrees to issue  letters of
credit  hereunder from time to time before the Bridge  Termination Date upon the
request of the Borrower (such letters of credit issued,  the "Bridge  Letters of
Credit");  provided that, immediately after each such Bridge Letter of Credit is
issued,  the aggregate amount of the Bridge Letter of Credit Liabilities for all
Bridge Letters of Credit shall not exceed the Available  Bridge LC Amount.  Upon
the date of  issuance  by the  Bridge  LC Bank of a Bridge  Letter  of Credit in
accordance  with this Section 2.15, the Bridge LC Bank shall be deemed,  without
further  action by any party hereto,  to have sold to each Bridge Bank, and each
Bridge Bank shall be deemed, without further action by any party hereto, to have
purchased  from the Bridge LC Bank,  a  participation  in such Bridge  Letter of
Credit and the related Bridge Letter of Credit  Liabilities in proportion to its
Percentage.

                  (b) The Borrower  shall give the Bridge LC Bank at least three
Business Days' prior notice  (effective  upon receipt)  specifying the date each
Bridge Letter of Credit is to be issued,  and  describing  the proposed terms of
such Bridge Letter of Credit and the nature of the  transactions  proposed to be
supported thereby. Upon receipt of such notice the Bridge LC Bank shall promptly
notify the Agent,  and the Agent shall  promptly  notify each Bridge Bank of the
contents  thereof and of the amount of such Bridge Bank's  participation in such
proposed  Bridge  Letter of Credit.  The  issuance  by the Bridge LC Bank of any
Bridge Letter of Credit shall, in addition to the conditions precedent set forth
in Article III (the  satisfaction of which the Bridge LC Bank shall have no duty
to ascertain), be subject to the conditions precedent that such Bridge Letter of
Credit shall be  satisfactory  to the Bridge LC Bank and that the Borrower shall
have executed and delivered such other  instruments  and agreements  relating to
such  Bridge  Letter of  Credit as the  Bridge  LC Bank  shall  have  reasonably
requested. Each Bridge Letter of Credit shall have an expiry date not later than
the Bridge Termination Date.

                  (c) The Borrower shall pay to the Agent a letter of credit fee
at a rate equal to (i) 1.75% per annum on the  aggregate  amount  available  for
drawings under each Performance Bridge Letter of Credit issued from time to time
and (ii) 2.75% per annum on the aggregate  amount  available for drawings  under
each Financial Bridge Letter of Credit issued from time to time, any such fee to
be payable for the account of the Bridge Banks  ratably in  proportion  to their
Percentages. Such fee shall be payable in arrears on the last day of each fiscal
quarter  of the  Borrower  for so  long as  such  Bridge  Letter  of  Credit  is
outstanding  and on the date of termination  thereof.  The Borrower shall pay to
the Bridge LC Bank  additional fees and expenses in the amounts and at the times
as agreed between the Borrower and the Bridge LC Bank.

                  (d) Upon receipt from the  beneficiary of any Bridge Letter of
Credit of any demand for payment or other  drawing  under such Bridge  Letter of
Credit,  the Bridge LC Bank shall notify the Agent and the Agent shall  promptly
notify the  Borrower and each other Bridge Bank as to the amount to be paid as a
result  of  such  demand  or  drawing  and  the  respective  payment  date.  The
responsibility  of the Bridge LC Bank to the Borrower and each Bridge Bank shall
be only to determine  that the documents  (including  each demand for payment or
other  drawing)  delivered  under each Bridge  Letter of Credit  issued by it in
connection with such presentment shall be in conformity in all material respects
with such Bridge Letter of Credit. The Bridge LC Bank shall endeavor to exercise
the same care in the issuance and administration of the Bridge Letters of Credit
as it does with  respect  to letters  of credit in which no  participations  are
granted,  it being  understood  that in the absence of any gross  negligence  or
willful misconduct by the Bridge LC Bank, each Bridge Bank severally agrees that
it shall  be  unconditionally  and  irrevocably  liable  without  regard  to the
occurrence of any Event of Default or any condition  precedent  whatsoever,  pro
rata to the extent of such Bridge Bank's Percentage,  to reimburse the Bridge LC
Bank on demand for the amount of each  payment  made by the Bridge LC Bank under
each  Bridge  Letter of Credit  issued by the Bridge LC Bank to the extent  such
amount is not  reimbursed by the Borrower  pursuant to clause (e) below together
with  interest on such amount for each day from the date of the Bridge LC Bank's
demand for such payment  (or, if such demand is made after 11:00 A.M.  (New York
City time) on such date, from the next  succeeding  Business Day) to the date of
payment by such Bridge Bank of such amount at a rate of interest per annum equal
to the Federal Funds Rate for such day.

                  (e) The  Borrower  shall be  irrevocably  and  unconditionally
obligated  forthwith to reimburse the Bridge LC Bank for any amounts paid by the
Bridge LC Bank upon any  drawing  under any  Bridge  Letter of  Credit,  without
presentment,  demand,  protest or other  formalities of any kind;  provided that
neither  the  Borrower  nor any  Bridge  Bank  shall  hereby be  precluded  from
asserting any claim for direct (but not  consequential)  damages suffered by the
Borrower or such Bridge  Bank to the extent,  but only to the extent,  caused by
(i)  the  willful  misconduct  or  gross  negligence  of the  Bridge  LC Bank in
determining  whether  a request  presented  under  any  Bridge  Letter of Credit
complied  with the terms of such  Bridge  Letter  of Credit or (ii) such  Bridge
Bank's  failure to pay under any Bridge Letter of Credit after the  presentation
to it of a request  strictly  complying  with the terms  and  conditions  of the
Bridge  Letter  of  Credit.  All such  amounts  paid by the  Bridge  LC Bank and
remaining  unpaid by the Borrower  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
applicable  to Bridge  Loans for such day.  The  Bridge LC Bank will pay to each
Bridge Bank ratably in accordance with its Percentage all amounts  received from
the  Borrower for  application  in payment,  in whole or in part,  of the Bridge
Reimbursement  Obligation in respect of any Bridge Letter of Credit, but only to
the extent such Bridge Bank has made payment to the Bridge LC Bank in respect of
such Bridge Letter of Credit pursuant to Section 2.15(d).

                  (f) If after the date hereof,  the adoption of any  applicable
law,  rule  or  regulation,  or  any  change  in any  applicable  law,  rule  or
regulation, or any change in the interpretation or administration thereof by any
governmental  authority,  central  bank or  comparable  agency  charged with the
interpretation or administration  thereof, or compliance by any Bridge Bank with
any  request or  directive  (whether or not having the force of law) of any such
authority,  central  bank or  comparable  agency  shall  impose,  modify or deem
applicable any tax, reserve,  special deposit or similar  requirement against or
with respect to or measured by reference to Bridge  Letters of Credit  issued or
to be issued  hereunder or  participations  therein,  and the result shall be to
increase the cost to any Bridge Bank of issuing or maintaining any Bridge Letter
of Credit or any participation  therein,  or reduce any amount receivable by any
Bridge Bank hereunder in respect of any Bridge Letter of Credit (which  increase
in cost, or reduction in amount  receivable,  shall be the result of such Bridge
Bank's  reasonable  allocation of the aggregate of such  increases or reductions
resulting from such event),  then, upon demand by such Bridge Bank (which demand
shall not be unreasonably  delayed,  provided that a demand within six months of
the accrual of such increased cost or reduction in amount receivable will not be
deemed to be  unreasonably  delayed),  the Borrower agrees to pay to such Bridge
Bank,  from time to time as  specified  by such  Bridge  Bank,  such  additional
amounts as shall be sufficient to compensate such Bridge Bank for such increased
costs or  reductions in amount  incurred by such Bridge Bank. A  certificate  of
such  Bridge  Bank  submitted  by such  Bridge  Bank to the  Borrower  shall  be
conclusive as to the amount thereof in the absence of manifest error.

                  (g) The Borrower's  obligations  under this Section 2.15 shall
be absolute and  unconditional  under any and all circumstances and irrespective
of any setoff, counterclaim or defense to payment which the Borrower may have or
have had against the Bridge LC Bank,  any Bridge  Bank or any  beneficiary  of a
Bridge Letter of Credit. The Borrower further agrees with the Bridge LC Bank and
the  Bridge  Banks that the  Bridge LC Bank and the  Bridge  Banks  shall not be
responsible for, and the Borrower's Bridge  Reimbursement  Obligation in respect
of any Bridge Letter of Credit shall not be affected by, among other things, the
validity or genuineness  of documents or of any  endorsements  thereon,  even if
such  documents  should  in fact  prove  to be in any or all  respects  invalid,
fraudulent or forged,  or any dispute between or among the Borrower,  any of its
Subsidiaries,  the  beneficiary  of any Bridge Letter of Credit or any financing
institution  or  other  party  to  whom  any  Bridge  Letter  of  Credit  may be
transferred  or any claims or defenses  whatsoever of the Borrower or any of its
Subsidiaries  against the beneficiary of any Bridge Letter of Credit or any such
transferee.  The Bridge LC Bank  shall not be liable  for any  error,  omission,
interruption  or delay in  transmission,  dispatch or delivery of any message or
advice,  however  transmitted,  in  connection  with any Bridge Letter of Credit
issued,  extended or renewed by it. The Borrower agrees that any action taken or
omitted  by the Bridge LC Bank or any Bridge  Bank under or in  connection  with
each Bridge Letter of Credit and the related  drafts and  documents,  if done in
good faith and without gross negligence,  shall be binding upon the Borrower and
shall not put the Bridge LC Bank or any Bridge Bank under any  liability  to the
Borrower.

                  (h) To the extent not inconsistent  with clause (g) above, the
Bridge  LC Bank  shall be  entitled  to rely,  and shall be fully  protected  in
relying upon, any Bridge Letter of Credit, draft, writing,  resolution,  notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype  message,  statement,  order or  other  document  believed  by it to be
genuine and correct and to have been signed,  sent or made by the proper  Person
or  Persons  and  upon  advice  and  statements  of legal  counsel,  independent
accountants and other experts selected by the Bridge LC Bank. The Bridge LC Bank
shall be fully  justified  in failing or refusing to take any action  under this
Agreement  unless it shall first have received such advice or concurrence of the
Required  Bridge Banks as it reasonably  deems  appropriate or it shall first be
indemnified to its reasonable  satisfaction  by the Bridge Banks against any and
all  liability  and  expense  which may be incurred by it by reason of taking or
continuing to take any such action.  Notwithstanding any other provision of this
Section  2.15,  the  Bridge  LC Bank  shall in all cases be fully  protected  in
acting, or in refraining from acting,  under this Agreement in accordance with a
request of the Required  Bridge Banks,  and such request and any action taken or
failure to act pursuant  thereto  shall be binding upon the Bridge Banks and all
future   holders   of   participations   in  any   Bridge   Letters  of  Credit.

                  (i) The Borrower  hereby  indemnifies  and holds harmless each
Bridge  Bank and the Agent from and  against  any and all  claims  and  damages,
losses,  liabilities,  costs or expenses which such Bridge Bank or the Agent may
incur (or which may be  claimed  against  such  Bridge  Bank or the Agent by any
Person whatsoever) by reason of or in connection with the execution and delivery
or transfer  of or payment or failure to pay under any Bridge  Letter of Credit,
including,  without limitation, any claims, damages, losses, liabilities,  costs
or  expenses  which the  Bridge LC Bank may incur by reason of or in  connection
with the  failure  of any  other  Bridge  Bank to  fulfill  or  comply  with its
obligations to the Bridge LC Bank hereunder (but nothing herein  contained shall
affect any rights the Borrower may have against such  defaulting  Bridge  Bank);
provided that the Borrower shall not be required to indemnify any Bridge Bank or
the Agent for any claims, damages, losses, liabilities, costs or expenses to the
extent,  but only to the extent,  caused by (i) the willful  misconduct or gross
negligence  of the  Bridge LC Bank in  determining  whether a request  presented
under any Bridge Letter of Credit  complied with the terms of such Bridge Letter
of Credit or (ii) the Bridge LC Bank's failure to pay under any Bridge Letter of
Credit after the  presentation  to it of a request  strictly  complying with the
terms and  conditions  of the Bridge  Letter of Credit.  Nothing in this Section
2.15(i) is intended to limit the  obligations  of the  Borrower  under any other
provision of this Agreement.

                  (j) Each  Bridge Bank shall,  ratably in  accordance  with its
Percentage,  indemnify the Bridge LC Bank, its  affiliates and their  respective
directors,  officers,  agents and employees (to the extent not reimbursed by the
Borrower)  against any cost,  expense  (including  reasonable  counsel  fees and
disbursements),  claim, demand, action, loss or liability (except such as result
from such indemnitees'  gross negligence or willful  misconduct or the Bridge LC
Bank's  failure to pay under any Bridge Letter of Credit after the  presentation
to it of a request  strictly  complying  with the terms  and  conditions  of the
Bridge Letter of Credit) that such indemnitees may suffer or incur in connection
with this  Section  2.15 or any  action  taken or  omitted  by such  indemnitees
hereunder.

                  (k) In its  capacity as a Bridge Bank the Bridge LC Bank shall
have the same rights and obligations as any other Bridge Bank.

                  SECTION 2.16.  Taxes.  (a) For purposes of this  Section,  the
following terms have the following meanings:

                  "Taxes"  means any and all  present or future  taxes,  duties,
levies, imposts, deductions, charges or withholdings with respect to any payment
by the Borrower  pursuant to this  Agreement  or under any Bridge Note,  and all
liabilities with respect thereto,  excluding (i) in the case of each Bridge Bank
and the Agent,  taxes  imposed on its income,  and  franchise  or similar  taxes
imposed on it, by a jurisdiction under the laws of which such Bridge Bank or the
Agent  (as the case may be) is  organized  or in which its  principal  executive
office is located  or, in the case of each  Bridge  Bank,  in which its  Lending
Office is located and (ii) in the case of each Bridge  Bank,  any United  States
withholding tax imposed on such payments but only to the extent that such Bridge
Bank is subject to United  States  withholding  tax at the time such Bridge Bank
first becomes a party to this Agreement.

                  "Other Taxes" means any present or future stamp or documentary
taxes and any other  excise or  property  taxes,  or similar  charges or levies,
which arise from any payment made pursuant to this Agreement or under any Bridge
Note or from the  execution or delivery  of, or otherwise  with respect to, this
Agreement or any Bridge Note.

                  (b) Any and all payments by the Borrower to or for the account
of any Bridge Bank or the Agent hereunder or under any Bridge Note shall be made
without  deduction for any Taxes or Other Taxes;  provided that, if the Borrower
shall be  required  by law to  deduct  any  Taxes or Other  Taxes  from any such
payments,  the sum payable hereunder or under any Bridge Note to any Bridge Bank
or the Agent,  (i) the sum payable shall be increased as necessary so that after
making all required deductions  (including  deductions  applicable to additional
sums payable  under this Section) such Bridge Bank or the Agent (as the case may
be)  receives  an amount  equal to the sum it would  have  received  had no such
deductions  been made, (ii) the Borrower shall make such  deductions,  (iii) the
Borrower shall pay the full amount deducted to the relevant  taxation  authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Agent,  at its address  referred to in Section 8.01, the original
or a certified copy of a receipt evidencing payment thereof.

                  (c) In addition, the Borrower agrees to pay all Other Taxes.

                  (d) The Borrower  agrees to indemnify each Bridge Bank and the
Agent  for  the  full  amount  of  Taxes  or  Other  Taxes  (including,  without
limitation,  any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts  payable  under this  Section) paid by such Bridge Bank or the Agent (as
the case may be) and any liability (including penalties,  interest and expenses)
arising therefrom or with respect thereto.  This  indemnification  shall be paid
within 15 days  after such  Bridge  Bank or the Agent (as the case may be) makes
demand therefor.

                  (e)  Each   Bridge  Bank   organized   under  the  laws  of  a
jurisdiction outside the United States, on or prior to the date of its execution
and  delivery  of this  Agreement  in the case of each Bridge Bank listed on the
signature  pages hereof and on or prior to the date on which it becomes a Bridge
Bank in the case of each other Bridge Bank, and from time to time  thereafter if
requested  in  writing by the  Borrower  (but only so long as such  Bridge  Bank
remains  lawfully able to do so),  shall provide the Borrower and the Agent with
Internal  Revenue  Service form 1001 or 4224, as  appropriate,  or any successor
form  prescribed by the Internal  Revenue  Service,  certifying that such Bridge
Bank is  entitled  to  benefits  under an income  tax treaty to which the United
States is a party which exempts the Bridge Bank from United  States  withholding
tax or reduces the rate of  withholding  tax on  payments  of  interest  for the
account of such Bridge Bank or certifying that the income receivable pursuant to
this Agreement is effectively  connected with the conduct of a trade or business
in the United  States.  If the form  provided  by a Bridge Bank at the time such
Bridge Bank first  becomes a party to this  Agreement  indicates a United States
interest  withholding  tax rate in excess of zero,  withholding tax at such rate
shall be considered  excluded from "Taxes" as defined in subsection  (a) of this
Section.

                  (f) For any period  with  respect  to which a Bridge  Bank has
failed to provide the Borrower or the Agent with the  appropriate  form pursuant
to  subsection  (d) of this  Section  (unless such failure is due to a change in
treaty,  law or regulation  occurring  subsequent to the date on which such form
originally was required to be provided),  such Bridge Bank shall not be entitled
to  indemnification  under subsection (b) or (c) of this Section with respect to
Taxes imposed by the United  States;  provided  that if a Bridge Bank,  which is
otherwise  exempt from or subject to a reduced rate of withholding  tax, becomes
subject to Taxes  because of its failure to deliver a form  required  hereunder,
the Borrower shall take such steps as such Bridge Bank shall reasonably  request
to assist such Bridge Bank to recover such Taxes.

                  (g) If the Borrower is required to pay  additional  amounts to
or for the account of any Bridge Bank pursuant to this Section, then such Bridge
Bank will change the  jurisdiction  of its Lending Office if, in the judgment of
such Bridge Bank,  such change (i) will eliminate or reduce any such  additional
payment which may thereafter  accrue and (ii) if such change, in the judgment of
such Bridge Bank, is not otherwise disadvantageous to such Bridge Bank.

                                   ARTICLE III
                                   CONDITIONS

                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

                  The Borrower represents and warrants that:

                  SECTION 4.01. Corporate Existence and Power. The Borrower is a
corporation duly  incorporated,  validly existing and in good standing under the
laws  of   Massachusetts,   and  has  all  corporate  powers  and  all  material
governmental licenses, authorizations,  consents and approvals required to carry
on its business as now conducted.

                  SECTION 4.02.  Corporate and  Governmental  Authorization;  No
Contravention.  (a) The execution,  delivery and  performance by each Obligor of
the Financing  Documents to which it is a party are within its corporate powers,
have been duly authorized by all necessary  corporate action,  require no action
by or in respect of, or filing with, any governmental  body,  agency or official
and do  not  contravene,  or  constitute  a  default  under,  any  provision  of
applicable law or regulation or of the certificate of  incorporation  or by-laws
of such Obligor or of any  agreement,  judgment,  injunction,  order,  decree or
other instrument  binding upon such Obligor or any of its Subsidiaries or result
in the  creation  or  imposition  of  any  Lien,  except  Liens  created  by the
Collateral Documents, on any asset of such Obligor or any of its Subsidiaries.

                  (b) The execution, delivery and performance by each Obligor of
the  amendments  to the  Financing  Documents  to  which  it is a party  and the
performance by each Obligor of the Financing  Documents as so amended are within
its corporate  powers,  have been duly  authorized  by all  necessary  corporate
action,  require no action by or in respect of, or filing with, any governmental
body,  agency or official and do not contravene,  or constitute a default under,
any  provision  of  applicable  law  or  regulation  or of  the  certificate  of
incorporation  or  by-laws  of  such  Obligor  or of  any  agreement,  judgment,
injunction,  order,  decree or other instrument binding upon such Obligor or any
of its Subsidiaries or result in the creation or imposition of any Lien,  except
Liens created by the  Collateral  Documents as so amended,  on any asset of such
Obligor or any of its Subsidiaries.

                  SECTION 4.03. Binding Effect;  Liens of Collateral  Documents.
(a) This Agreement constitutes a valid and binding agreement of the Borrower and
the Bridge Notes, when executed and delivered in accordance with this Agreement,
will  constitute  valid and  binding  obligations  of the  Borrower in each case
enforceable in accordance with their  respective  terms.  The Borrower  Security
Agreement and the Subsidiary  Pledge  Agreement,  when executed and delivered in
accordance with this Agreement,  will constitute valid and binding agreements of
each Obligor party thereto  enforceable  against each such Obligor in accordance
with their respective  terms.  Each amendment to each Financing  Document,  when
executed and delivered in accordance  with this  Agreement,  and each  Financing
Document as so amended  will  constitute  a valid and binding  agreement  of the
Obligor party thereto in each case enforceable in accordance with its terms.

                  (b) All real  property  in which  the  Borrower  or any of its
Subsidiaries  has an  interest,  directly  or  indirectly  (whether  through  an
interest in a joint venture or  partnership  or otherwise) as of the date hereof
is listed in Part 1 of Schedule III hereto. The list of property of the Borrower
and each of its  Subsidiaries,  security  interests  in which  are  governed  by
Article IX of the UCC as in effect in the relevant  jurisdictions,  set forth in
Part 2 of  Schedule  III  hereto  is  complete  in all  material  respects.  The
location,  ownership,  status and lien information  provided in Schedule III for
each item of real  property and each type of personal  property are complete and
correct.

                  (c) The Collateral  Documents create valid security  interests
in, and first mortgage Liens on, the Collateral purported to be covered thereby,
which  security  interests  and  mortgage  Liens are and will  remain  perfected
(except  in the  case of  inventory  located  at  construction  sites)  security
interests  and duly  recorded  mortgage  Liens,  prior to all other Liens except
Liens permitted by the Collateral Documents.

                  SECTION 4.04.  Financial Information.

                  (a) The  consolidated  balance  sheet of the  Borrower and its
Consolidated  Subsidiaries as of December 31, 1994 and the related  consolidated
statements  of income,  stockholders'  equity and cash flows for the fiscal year
then ended, reported on by Arthur Andersen & Co. and set forth in the Borrower's
1994 Form 10-K, a copy of which has been  delivered to each of the Bridge Banks,
fairly present, in conformity with generally accepted accounting principles, the
consolidated   financial   position  of  the  Borrower   and  its   Consolidated
Subsidiaries  as of such date and their  consolidated  results of operations and
cash flows for such fiscal year.

                  (b) The unaudited  consolidated  balance sheet of the Borrower
and its  Consolidated  Subsidiaries  as of  September  30,  1995 and the related
unaudited consolidated statements of income, stockholders' equity and cash flows
for the nine months then ended, set forth in the Borrower's quarterly report for
the fiscal  quarter ended  September 30, 1995 as filed with the  Securities  and
Exchange  Commission on Form 10-Q, a copy of which has been delivered to each of
the  Bridge  Banks,  fairly  present,  in  conformity  with  generally  accepted
accounting   principles  applied  on  a  basis  consistent  with  the  financial
statements  referred to in  subsection  (a) of this  Section,  the  consolidated
financial position of the Borrower and its Consolidated  Subsidiaries as of such
date and their  consolidated  results of operations and cash flows for such nine
month period (subject to normal year-end adjustments).

                  (c)  Since  September  30,  1995  there  has been no  material
adverse  change in the business,  financial  position,  results of operations or
prospects of the Borrower and its  Consolidated  Subsidiaries,  considered  as a
whole.

                  SECTION   4.05.   Litigation.   Except  as  disclosed  in  the
Borrower's  1994 Form  10-K and the Form 10-Q  referred  to in  Section  4.04(b)
above,  there  is no  action,  suit or  proceeding  pending  against,  or to the
knowledge of the Borrower  threatened against or affecting,  the Borrower or any
of its  Subsidiaries  before any court or arbitrator or any  governmental  body,
agency or  official  in which there is a  reasonable  possibility  of an adverse
decision  which could  materially  adversely  affect the business,  consolidated
financial position or consolidated results of operations of the Borrower and its
Consolidated  Subsidiaries  or which  in any  manner  draws  into  question  the
validity of any Financing Document.

                  SECTION 4.06.  Compliance with ERISA. Each member of the ERISA
Group has fulfilled its obligations under the minimum funding standards of ERISA
and the Internal  Revenue Code with respect to each Plan and is in compliance in
all material respects with the presently applicable  provisions of ERISA and the
Internal  Revenue Code with  respect to each Plan.  No member of the ERISA Group
has (i) sought a waiver of the minimum funding standard under Section 412 of the
Internal  Revenue  Code  in  respect  of any  Plan,  (ii)  failed  to  make  any
contribution or payment to any Plan or  Multiemployer  Plan or in respect of any
Benefit  Arrangement,  or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could result in the imposition of a Lien or the posting of
a bond or other  security  under  ERISA or the  Internal  Revenue  Code or (iii)
incurred  any  liability to the PBGC or any other Person under Title IV of ERISA
other than a liability to the PBGC for premiums under Section 4007 of ERISA.

                  SECTION 4.07.  Environmental Matters. 

                  (a) In the  ordinary  course  of its  business,  the  Borrower
conducts  periodic reviews of the effect of Environmental  Laws on the business,
operations  and properties of the Borrower and its  Subsidiaries  and compliance
therewith. The Borrower and its Subsidiaries also attempt, whenever possible, to
negotiate  specific  provisions  in contracts  for  construction  services  that
allocate to the  contracting  governmental  agency or private owner,  the entire
risk and responsibility for Hazardous  Substances  encountered during the course
of  construction.  On the basis of such  reviews  and  contract  provisions  and
procedures,  the Borrower has reasonably concluded that the costs and associated
liabilities  of  compliance  with  Environmental  Laws  are  unlikely  to have a
material  adverse  effect  on the  business,  financial  condition,  results  of
operations  or  prospects of the  Borrower  and its  Consolidated  Subsidiaries,
considered as a whole.

                  (b) Without limiting the foregoing, as of the Bridge Effective
Date:

                  (i) no notice, notification,  demand, request for information,
         citation, summons, complaint or order has been issued, no complaint has
         been filed, no penalty has been assessed and no investigation or review
         is pending or, to the  knowledge  of the  Obligors,  threatened  by any
         governmental or other entity with respect to any (A) alleged  violation
         by the Borrower or any of its  Subsidiaries  of any  Environmental  Law
         involving any Mortgaged  Facility,  (B) alleged failure by the Borrower
         or  any  of  its  Subsidiaries  to  have  any   environmental   permit,
         certificate,  license, approval, registration or authorization required
         in  connection  with  the  conduct  of its  business  at any  Mortgaged
         Facility,  (C) Regulated Activity conducted at any Addtional  Mortgaged
         Facility or (D) Release of  Hazardous  Substances  at or in  connection
         with any Mortgaged Facility;

                  (ii)  other  than   generation  of  Hazardous   Substances  in
         compliance  with  all  applicable   Environmental  Laws,  no  Regulated
         Activity has occurred at or on any Mortgaged Facility;

                  (iii) no polychlorinated biphenyls, radioactive material, urea
         formaldehyde,   lead,   asbestos,   asbestos-  containing  material  or
         underground  storage tank (active or  abandoned) is or has been present
         at any Mortgaged Facility;

                  (iv) no Hazardous  Substance has been Released (and no written
         notification of such Release has been filed) or is present  (whether or
         not in a reportable or threshold planning quantity) at, on or under any
         Mortgaged Facility;

                  (v) no  Mortgaged  Facility is listed or, to the  knowledge of
         the Obligors,  proposed for listing,  on the National  Priorities  List
         promulgated pursuant to CERCLA, on CERCLIS (as defined in CERCLA) or on
         any  similar  federal,   state  or  foreign  list  of  sites  requiring
         investigation or clean-up; and

                  (vi)  there  are no  Liens  under  Environmental  Laws  on any
         Mortgaged  Facility,  no  government  actions have been taken or are in
         process which could  subject any  Mortgaged  Property to such Liens and
         neither the Borrower nor any of its  Subsidiaries  would be required to
         place any notice or restriction relating to Hazardous Substances in any
         deed to any Mortgaged Facility.

                  (c) No environmental investigation, study, audit, test, review
or other  analysis has been  conducted of which the Obligors  have  knowledge in
relation to any Mortgaged  Facility  which has not been  delivered to the Bridge
Banks.

                  SECTION 4.08. Taxes.  United States Federal income tax returns
of the Borrower and its  Subsidiaries  have been examined and closed through the
fiscal year ended  December 31, 1989.  The  Borrower and its  Subsidiaries  have
filed all United States  Federal  income tax returns and all other  material tax
returns  which  are  required  to be filed by them and have  paid all  taxes due
pursuant to such returns or pursuant to any assessment  received by the Borrower
or any  Subsidiary.  The  charges,  accruals  and  reserves  on the books of the
Borrower and its Subsidiaries in respect of taxes or other governmental  charges
are, in the opinion of the Borrower, adequate.

                  SECTION 4.09. Subsidiaries. All of the Borrower's Subsidiaries
and all joint  ventures  and  partnerships  in which the  Borrower or any of its
Subsidiaries  have an  interest  as of the date hereof are listed in Schedule VI
hereto and the state of incorporation or organization and the ownership interest
of each Subsidiary, joint venture and partnership specified therein are complete
and correct. Each of the Borrower's corporate Subsidiaries is a corporation duly
incorporated,  validly  existing  and in good  standing  under  the  laws of its
jurisdiction  of  incorporation,  and has all corporate  powers and all material
governmental licenses, authorizations,  consents and approvals required to carry
on its business as now conducted.

                  SECTION 4.10. Not an Investment  Company.  The Borrower is not
an  "investment  company"  within the meaning of the  Investment  Company Act of
1940, as amended.

                  SECTION  4.11.  No  Burdensome  Restrictions;  No  Derivatives
Obligations;  Certain Existing Agreements.  (a) No contract, lease, agreement or
other  instrument to which the Borrower or any of its Subsidiaries is a party or
by which  any of its  property  is  bound  or  affected,  no  charge,  corporate
restriction,  judgment,  decree or order and no provision of  applicable  law or
governmental  regulation  has  or  is  reasonably  expected  to  materially  and
adversely affect the business, operations or financial condition of the Borrower
and its  Consolidated  Subsidiaries,  taken as a whole,  or the  ability  of the
Borrower to perform its obligations under this Agreement.

                  (b) Neither the Borrower nor any of its  Subsidiaries is party
to any Derivatives Obligation except the Rincon Swap.

                  (c) All  agreements  to which the  Borrower or any  Subsidiary
Guarantor  is a  party  or by  which  it is  bound  (other  than  the  Financing
Documents) containing a negative pledge or limitations on its incurrence of Debt
or sale of assets are listed on Schedule IV hereto.

                  SECTION 4.12.  Full  Disclosure.  All  information  heretofore
furnished  by the Borrower to the Agent or any Bridge Bank for purposes of or in
connection  with this Agreement or any transaction  contemplated  hereby is, and
all such  information  hereafter  furnished  by the Borrower to the Agent or any
Bridge Bank will be, true and accurate in all material  respects (or in the case
of projections  and similar  information  based on reasonable  estimates) on the
date as of which such  information  is stated or  certified.  The  Borrower  has
disclosed to the Bridge Banks in writing any and all facts which  materially and
adversely  affect or may  reasonably  be expected to  materially  and  adversely
affect (to the extent the Borrower can now  reasonably  foresee),  the business,
operations  or  financial   condition  of  the  Borrower  and  its  Consolidated
Subsidiaries,  taken as a whole,  or the ability of the  Borrower to perform its
obligations under this Agreement.

                  SECTION 4.13.  Ownership of Property;  Liens. The Borrower and
its Subsidiaries  have good and marketable title to and are in lawful possession
of, or have valid  leasehold  interests in, or have the right to use pursuant to
valid  and  enforceable  agreements  or  arrangements,  all of their  respective
properties and other assets (real or personal,  tangible,  intangible or mixed),
except  where the  failure  to have or  possess  the same with  respect  to such
properties or other assets could not, in the aggregate,  have a material adverse
effect on the business,  financial condition, results of operations or prospects
of the Borrower and its Consolidated  Subsidiaries,  considered as a whole. None
of such  properties  or other  assets is  subject to any Lien  except  Permitted
Liens.

                                    ARTICLE V
                                    COVENANTS

Reimbursement Obligation with respect thereto remains unpaid:

Consolidated Tangible Net Worth of the Borrower will at no time be less than the
Minimum Compliance Level, determined as set forth below. The "Minimum Compliance
Level" is an amount equal to the Base Compliance Amount subject to increase (but
in no case subject to decrease) from time to time as follows:  (i) at the end of
each fiscal year commencing  after December 31, 1996 for which  Consolidated Net
Income is a positive  number,  the Minimum  Compliance  Level shall be increased
effective  at the last day of such fiscal year by an amount equal to 50% of such
Consolidated  Net Income;  and (ii) on the date of each issuance by the Borrower
subsequent to December 31, 1996 of any capital  stock or other equity  interest,
the Minimum Compliance Level shall be increased by an amount equal to 75% of the
amount of the net proceeds received by the Borrower on account of such issuance.
For purposes of this Section,  "Base  Compliance  Amount" means (i) for any date
during the period from and including December 31, 1995 to but excluding June 30,

                  SECTION 5.11.  Negative  Pledge.  Neither the Borrower nor any
Consolidated  Subsidiary of the Borrower will create,  assume or suffer to exist
any  Lien  on  any  asset  (including,  without  limitation,  capital  stock  of
Subsidiaries) now owned or hereafter acquired by it, except:

                  (a)  Liens   existing  on  December  31,  1995  securing  Debt
         outstanding on December 31, 1995 as described in Schedule II;

                  (b) any Lien existing on any asset of any  corporation  at the
         time such corporation becomes a Consolidated Subsidiary of the Borrower
         and not created in contemplation of such event;

                  (c) any Lien on any asset  securing  Debt  incurred or assumed
         for the purpose of  financing  all or any part of the cost of acquiring
         such asset, provided that such Lien attaches to such asset concurrently
         with or within  90 days  after the  acquisition  thereof  and such Lien
         secures only such Debt;

                  (d) any Lien on any asset of any  corporation  existing at the
         time  such  corporation  is  merged  or  consolidated  with or into the
         Borrower or a  Consolidated  Subsidiary of the Borrower and not created
         in contemplation of such event;

                  (e) any Lien  existing on any asset  prior to the  acquisition
         thereof by the Borrower or a  Consolidated  Subsidiary  of the Borrower
         and not created in contemplation of such acquisition;

                  (f)  any  Lien  arising  out  of the  refinancing,  extension,
         renewal or refunding  of any Debt secured by any Lien  permitted by any
         of the foregoing  clauses of this  Section,  provided that such Debt is
         not increased and is not secured by any additional assets;

                  (g)  Liens  incidental  to  conduct  of  its  business  or the
         ownership of its assets which (i) do not secure Debt and (ii) do not in
         the  aggregate  materially  detract  from the  value of its  assets  or
         materially impair the use thereof in the operation of its business;

                  (h)  Permitted Encumbrances;

                  (i) Liens (whether statutory, by contract or at common law and
         whether in the nature of a security  interest or constructive  trust or
         otherwise)  of  subcontractors,   architects,   engineers,   surveyors,
         laborers,  materialmen,  bonding companies and other Persons performing
         labor or services or providing  material for  construction  projects in
         and under  construction  contracts  to which the Borrower or any of its
         Subsidiaries is a party as general or prime  contractor,  subcontractor
         or construction manager;

                  (j) Liens  granted to the  Bonding  Company to secure  amounts

         Bonding Company on behalf of the Borrower or any of its Subsidiaries in
         the ordinary course of their respective businesses; and

                  (k)      Liens created by the Collateral Documents.

                  SECTION 5.12. Consolidations, Mergers and Sales of Assets. (a)
The Borrower will not (i)  consolidate or merge with or into any other Person or
sell,  lease or otherwise  transfer all or any substantial part of its assets to
any other Person or (ii) permit any Material Subsidiary (other than a Subsidiary
Guarantor)  to  consolidate  or  merge  with or  into,  or  transfer  all or any
substantial  part of its  assets to, any  Person  other than the  Borrower  or a
Wholly-Owned  Consolidated Subsidiary;  provided that the Borrower or a Material
Subsidiary other than Perini Land and Development may sell or otherwise transfer
assets  if  Aggregate  Asset  Sale  Proceeds  after  such  sale  less  Aggregate
Reinvested  Proceeds does not at any time exceed  $15,000,000.  "Aggregate Asset
Sale  Proceeds"  means  the  sum  of the  proceeds  of  each  sale  in a  single
transaction or series of related transactions by the Borrower or any Subsidiary,
on or after the Bridge  Effective  Date,  of fixed assets  yielding  proceeds in
excess of 5% of the Consolidated Tangible Net Worth of the Borrower.  "Aggregate
Reinvested  Proceeds"  means the amount of Aggregate Asset Sale Proceeds used to
purchase fixed assets for use in the same general business  presently  conducted
by the Borrower or the Subsidiary  that realized such proceeds,  as the case may
be, provided such proceeds are so used within 18 months of receipt thereof.  The
Borrower will not permit any  Subsidiary  Guarantor to consolidate or merge with
or into, or transfer all or any  substantial  part of its assets to, any Person;
provided that the foregoing shall not prohibit (i) any Subsidiary Guarantor from
selling,  leasing or otherwise transferring assets in the ordinary course of its
business  or (ii) R. E.  Dailey & Co.  from  transferring  all of its  assets to
Perini Building Company.

                  (b) The  Borrower  will not,  and will not  permit  any of its
Subsidiaries  to,  sell,  lease or otherwise  dispose of any item of  Collateral
(except  Accounts,  Inventory  and items listed in Schedule VII hereto up to the
amounts specified  therein) unless (i) each of the Bridge Banks shall have given
its prior written consent thereto and (ii) the consideration  therefor (x) shall
be at least equal to the fair market value of such asset (as  determined in good
faith  by a  financial  officer  of the  Borrower  or,  if  such  value  exceeds
$15,000,000,  by the board of directors  of the  Borrower or a duly  constituted
committee thereof) and (y) in the case of any agreement entered into on or after
the  Bridge  Effective  Date for the sale,  lease or other  disposition  of such
Collateral  shall  consist of cash payable at closing;  provided  that the prior
written consent of the Bridge Banks shall not be required for any sale, lease or
other  disposition  of any item of  Collateral  having a fair  market  value not
exceeding  $100,000 if the aggregate amount of the fair market value of all such
items of Collateral sold, leased or otherwise disposed of during any fiscal year
does not exceed  $500,000 and the Borrower  delivers to each of the Bridge Banks
prompt written notice of each such sale, lease or other disposition.

                  SECTION  5.13.  Use of  Proceeds.  The  proceeds of the Bridge
Loans  made  under  this  Agreement  will be used by the  Borrower  for  general
corporate  purposes  other than for making or carrying Real Estate  Investments.
None of such proceeds  will be used,  directly or  indirectly,  for the purpose,
whether immediate, incidental or ultimate, of purchasing or carrying any "margin
stock" within the meaning of Regulation U.

                  SECTION 5.14. Restricted Payments. The aggregate amount of all
dividends which  constitute  Restricted  Payments  declared and other Restricted
Payments  made during any period of four  consecutive  fiscal  quarters will not
exceed an amount  equal to 50% of the excess,  if any, of (x)  Consolidated  Net
Income  for such  period  over  (y) the  aggregate  amount  of  preferred  stock
dividends not  constituting  Restricted  Payments  paid during such period.  The
Borrower will not declare any dividend payable more than 120 days after the date
of declaration  thereof;  provided that the Borrower will not declare or pay any
preferred stock dividend until the Bridge Credit Agreement is repaid in full and
terminated.

                  SECTION 5.15. Real Estate Investments.  The Borrower will not,
and will  not  permit  any  Consolidated  Subsidiary  to,  make any Real  Estate
Investment if, after giving effect  thereto,  the cumulative  amount of Net Real
Estate  Investments made (i) at any time during the period beginning  January 1,
1996 and ending  December  31, 1996 shall exceed  $4,000,000  or (ii) during any
fiscal year thereafter shall exceed  $4,000,000 plus 25% of the amount,  if any,
by which the Net Real Estate  Investments  made during the preceding period were
less  than the  applicable  limitation  specified  above  for such  period.  For
purposes of this Section, the cumulative amount of "Net Real Estate Investments"
made during any period,  as  measured  at any date  during such  period,  is the
aggregate  amount  of  Real  Estate  Investments  made by the  Borrower  and its
Consolidated Subsidiaries from and including the first day of such period to and
including  such  date,  less  the sum of all  cash or cash  equivalent  payments
received by the Borrower or one of its  Consolidated  Subsidiaries,  as the case
may be, in respect of Real Estate  Investments  from and including the first day
of such period to and including such date.

                  SECTION 5.16. Other Investments.  Neither the Borrower nor any
Consolidated  Subsidiary will make or acquire any Investment in any Person other
than:

                  (a) Real Estate Investments permitted by Section 5.15;

                  (b) Investments in Subsidiaries or joint ventures  principally
         engaged in the construction business;

                  (c) Temporary Cash Investments; and

                  (d) any  Investment  not otherwise  permitted by the foregoing
         clauses of this Section if,  immediately  after such Investment is made
         or acquired,  the aggregate net book value of all Investments permitted
         by this  clause (d) does not  exceed 5% of  Consolidated  Tangible  Net
         Worth;

provided that no Real Estate  Investment may be made pursuant to clause (b), (c)
or (d) above.

                  SECTION 5.17. Further  Assurances.  (a) The Borrower will, and
will  cause  each of its  Subsidiaries  to,  at its sole cost and  expense,  do,
execute,  acknowledge  and deliver all such further  acts,  deeds,  conveyances,
mortgages,  assignments,  notices of assignment, transfers and assurances as the
Agent shall from time to time  request,  which may be  necessary or desirable in
the  reasonable  judgment  of the Agent  from time to time to  assure,  perfect,
convey,  assign,  transfer  and confirm  unto the Agent the  property and rights
conveyed or assigned pursuant to the Collateral Documents, or which the Borrower
or such Subsidiaries may be or may hereafter become bound to convey or assign to
the Agent or which may facilitate the performance of the terms of the Collateral
Documents or the filing, registering or recording of the Collateral Documents.

                  (b) All costs and  expenses in  connection  with the  security
interests and Liens created by the Collateral  Documents,  including  reasonable
legal  fees and other  reasonable  costs and  expenses  in  connection  with the
granting,  perfecting and maintenance of such security  interests and Liens, the
preparation,  execution,  delivery,  recordation  or filing of documents and any
other acts in connection with the grant of such security  interests and Liens as
the Agent may reasonably  request,  shall be paid by the Borrower  promptly when
due.

its behalf and to exercise  such powers  under the  Financing  Documents  as are
delegated to the Agent by the terms  thereof,  together  with all such powers as
are reasonably incidental thereto.

                  SECTION 7.02.  Agent and  Affiliates.  Morgan  Guaranty  Trust
Company of New York shall have the same  rights and powers  under the  Financing
Documents as any other  Bridge Bank and may exercise or refrain from  exercising
the same as though it were not the Agent,  and Morgan  Guaranty Trust Company of
New York and its  affiliates  may  accept  deposits  from,  lend  money to,  and
generally  engage in any kind of business with the Borrower or any Subsidiary or
affiliate of the Borrower as if it were not the Agent hereunder.

                  SECTION 7.03.  Action by Agent.  The  obligations of the Agent
under the Financing Documents are only those expressly set forth herein. Without
limiting the  generality  of the  foregoing,  the Agent shall not be required to
take any action with  respect to any Default,  except as  expressly  provided in
Article VI.

                  SECTION 7.04. Consultation with Experts. The Agent may consult
with legal  counsel  (who may be counsel  for an  Obligor),  independent  public
accountants  and other  experts  selected  by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in  accordance  with the
advice of such counsel, accountants or experts.

                  SECTION 7.05. Liability of Agent. Neither the Agent nor any of
its  affiliates  nor any of their  respective  directors,  officers,  agents  or
employees  shall be liable for any action taken or not taken by it in connection
herewith (i) with the consent or at the request of the Required  Bridge Banks or
(ii) in the absence of its own gross negligence or willful  misconduct.  Neither
the  Agent  nor any of its  affiliates  nor any of their  respective  directors,
officers,  agents  or  employees  shall be  responsible  for or have any duty to
ascertain, inquire into or verify (i) any statement,  warranty or representation
made in connection with the Financing Documents or any borrowing hereunder; (ii)
the  performance  or  observance  of any of the  covenants or  agreements of the
Borrower;  (iii) the  satisfaction  of any  condition  specified in Article III,
except  receipt of items  required  to be  delivered  to the Agent;  or (iv) the
validity,  effectiveness  or genuineness of any Financing  Document or any other
instrument  or writing  furnished in  connection  herewith.  The Agent shall not
incur any liability by acting in reliance upon any notice, consent, certificate,
statement, or other writing (which may be a bank wire, telex or similar writing)
believed by it to be genuine or to be signed by the proper party or parties.

                  SECTION 7.06. Indemnification. Each Bridge Bank shall, ratably
in accordance with its Bridge  Commitment,  indemnify the Agent,  its affiliates
and their respective  directors,  officers,  agents and employees (to the extent
not reimbursed by the Borrower) against any cost, expense (including  reasonable
counsel  fees and  disbursements),  claim,  demand,  action,  loss or  liability
(except  such as result  from such  indemnitees'  gross  negligence  or  willful
misconduct)  that such  indemnitees  may suffer or incur in connection with this
Agreement or any action taken or omitted by such indemnitees hereunder.

                  SECTION 7.07.  Credit Decision.  Each Bridge Bank acknowledges
that it has,  independently  and  without  reliance  upon the Agent or any other
Bridge  Bank,  and based on such  documents  and  information  as it has  deemed
appropriate,  made its own  credit  analysis  and  decision  to enter  into this
Agreement.  Each Bridge Bank also acknowledges  that it will,  independently and
without  reliance  upon the Agent or any other  Bridge  Bank,  and based on such
documents and information as it shall deem appropriate at the time,  continue to
make its own credit  decisions  in taking or not  taking  any action  under this
Agreement.

                  SECTION  7.08.  Successor  Agent.  The Agent may resign at any
time by giving  notice  thereof to the Bridge Banks and the  Borrower.  Upon any
such  resignation,  the Required  Bridge Banks shall have the right to appoint a
successor  Agent.  If no  successor  Agent shall have been so  appointed  by the
Required Bridge Banks, and shall have accepted such appointment,  within 30 days
after the retiring  Agent gives notice of  resignation,  then the retiring Agent
may, on behalf of the Bridge Banks,  appoint a successor Agent, which shall be a
commercial  bank  organized or licensed  under the laws of the United  States of
America or of any State thereof and having a combined  capital and surplus of at
least $150,000,000. Upon the acceptance of its appointment as Agent hereunder by
a successor  Agent,  such successor Agent shall thereupon  succeed to and become
vested with all the rights and duties of the  retiring  Agent,  and the retiring
Agent shall be discharged from its duties and obligations  hereunder.  After any
retiring Agent's resignation  hereunder as Agent, the provisions of this Article
shall inure to its benefit as to any actions  taken or omitted to be taken by it
while it was Agent.

                  SECTION 7.09. Collateral Documents.  (a) As to any matters not
expressly  provided for in the  Collateral  Documents  (including the timing and
methods of realization upon the Collateral), the Agent shall act or refrain from
acting in accordance  with written  instructions  from the Required Bridge Banks
or, in the absence of such  instructions,  in  accordance  with its  discretion;
provided  that the Agent shall not be  obligated to take any action if the Agent
believes that such action is or may be contrary to any  applicable  law or might
cause  the  Agent  to  incur  any loss or  liability  for  which it has not been
indemnified to its satisfaction.

                  (b) The Agent  shall  not be  responsible  for the  existence,
genuineness or value of any of the  Collateral or for the validity,  perfection,
priority or enforceability  of the security  interests in any of the Collateral,
whether  impaired by  operation of law or by reason of any action or omission to
act on its part under the Collateral Documents.  The Agent shall have no duty to
ascertain or inquire as to the  performance or observance of any of the terms of
the Collateral Documents by any Obligor.


                                  ARTICLE VIII
                                  MISCELLANEOUS

                  SECTION  8.01.  Notices.  All  notices,   requests  and  other
communications to any party hereunder shall be in writing  (including bank wire,
telex,  facsimile  transmission  or similar  writing) and shall be given to such
party:  (x) in the case of the Borrower or the Agent, at its address or telex or
facsimile number set forth on the signature pages hereof, (y) in the case of any
Bridge  Bank,  at its  address  or telex or  facsimile  number  set forth in its
Administrative Questionnaire or (z) in the case of any party, such other address
or telex or facsimile number as such party may hereafter specify for the purpose
by notice to the Agent and the  Borrower.  Each such  notice,  request  or other
communication  shall be  effective  (i) if given by telex,  when  such  telex is
transmitted  to the telex number  specified in this Section and the  appropriate
answerback  is  received,  (ii) if given by  facsimile  transmission,  when such
facsimile is transmitted to the facsimile  number  specified in this Section and
receipt of such  facsimile is  confirmed,  either  orally or in writing,  by the
party  receiving such  transmission,  (iii) if given by certified mail, 72 hours
after such  communication  is  deposited  in the mails with first class  postage
prepaid,  addressed  as  aforesaid  or (iv) if given by any  other  means,  when
delivered at the address specified in this Section; provided that notices to the
Agent under Article II shall not be effective until received.

                  SECTION 8.02. No Waivers.  No failure or delay by the Agent or
any Bridge Bank in exercising any right,  power or privilege under any Financing
Document  shall  operate  as a waiver  thereof  nor shall any  single or partial
exercise  thereof preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. The rights and remedies therein provided
shall be cumulative and not exclusive of any rights or remedies provided by law.

                  SECTION 8.03.  Expenses;  Documentary Taxes;  Indemnification.
(a) The  Borrower  shall  pay  (i)  all  out-of-pocket  expenses  of the  Agent,
including fees and disbursements of special counsel for the Agent, in connection
with the preparation of the Financing Documents, any waiver or consent under any
Financing Document, or any amendment of any Financing Document or any Default or
alleged  Default  and (ii) if an  Event of  Default  occurs,  all  out-of-pocket
expenses  incurred  by the  Agent  and  each  Bridge  Bank,  including  fees and
disbursements  of counsel  (including  allocated  costs of internal  counsel and
disbursements of internal counsel), in connection with such Event of Default and
collection,  bankruptcy,  insolvency and other enforcement proceedings resulting
therefrom.  The Borrower  shall  indemnify each Bridge Bank against any transfer
taxes,  documentary  taxes,  assessments  or  charges  made by any  governmental
authority by reason of the execution and delivery of any Financing Document.

                  (b) The Borrower agrees to indemnify the Agent and each Bridge
Bank, their respective affiliates and the respective directors, officers, agents
and employees of the foregoing (each an  "Indemnitee")  and hold each Indemnitee
harmless from and against any and all liabilities,  losses,  damages,  costs and
expenses of any kind,  including,  without  limitation,  the reasonable fees and
disbursements  of counsel  (including  allocated  costs of internal  counsel and
disbursements of internal  counsel),  which may be incurred by any Indemnitee in
connection  with  any  investigative,   administrative  or  judicial  proceeding
(whether or not such Indemnitee  shall be designated a party thereto) brought or
threatened relating to or arising out of any Financing Document or any actual or
proposed use of proceeds of Bridge Loans hereunder;  provided that no Indemnitee
shall have the right to be indemnified hereunder for such Indemnitee's own gross
negligence  or  willful  misconduct  as  determined  by  a  court  of  competent
jurisdiction.

                  (c) The Borrower  agrees to indemnify each Indemnitee and hold
each  Indemnitee  harmless  from and  against any and all  liabilities,  losses,
damages, costs and expenses of any kind (including without limitation reasonable
expenses of  investigation by engineers,  environmental  consultants and similar
technical  personnel and reasonable fees and  disbursements of counsel including
allocated costs of internal counsel and  disbursements  of internal  counsel) of
any Indemnitee  arising out of, in respect of or in connection  with any and all
Environmental Liabilities. Without limiting the generality of the foregoing, the
Borrower  hereby  waives  all  rights for  contribution  or any other  rights of
recovery with respect to liabilities, losses, damages, costs or expenses arising
under or  related  to  Environmental  Laws  that it  might  have by  statute  or
otherwise against any Indemnitee.

                  SECTION 8.04. Sharing of Setoffs. Each Bridge Bank agrees that
if it shall,  by exercising  any right of setoff or  counterclaim  or otherwise,
receive payment of a proportion of the aggregate  amount due with respect to any
Bridge Loan or Bridge Reimbursement  Obligation owed to it which is greater than
the  proportion  received by any other  Bridge Bank in respect of the  aggregate
amount due with  respect to any Bridge Loan or Bridge  Reimbursement  Obligation
owed to such other Bridge Bank, the Bridge Bank  receiving such  proportionately
greater  payment  shall  purchase  such  participations  in the Bridge Loans and
Bridge Reimbursement  Obligations owed to the other Bridge Banks, and such other
adjustments  shall be made,  as may be required so that all such  payments  with
respect to the Bridge  Loans and Bridge  Reimbursement  Obligations  owed to the
Bridge  Banks shall be shared by the Bridge  Banks pro rata;  provided  that (i)
nothing in this  Section  shall  impair the right of any Bridge Bank to exercise
any right of setoff or  counterclaim it may have and to apply the amount subject
to such exercise to the payment of  indebtedness  of the Borrower other than its
indebtedness  hereunder  or under the Credit  Agreement  and (ii) nothing in any
Financing Documents shall require any Bridge Bank to share any payments received
by such Bridge  Bank if such  payments  were made in respect of any  obligations
(including  without  limitation  Other   Reimbursement   Obligations  and  Other
Mortgage/Lease   Obligations)   not   constituting   Bridge   Loans  or   Bridge
Reimbursement  Obligations.  The Borrower  agrees,  to the fullest extent it may
effectively do so under  applicable law, that any holder of a participation in a
Bridge Loan or Bridge Reimbursement Obligation, whether or not acquired pursuant
to the foregoing arrangements, may exercise rights of setoff or counterclaim and
other rights with respect to such  participation as fully as if such holder of a
participation  were a direct  creditor  of the  Borrower  in the  amount of such
participation.

                  SECTION 8.05.  Amendments  and Waivers.  Any provision of this
Agreement  or the Bridge  Notes may be  amended or waived if, but only if,  such
amendment or waiver is in writing and is signed by the Borrower and the Required
Bridge Banks (and, if the rights or duties of the Agent are affected thereby, by
it);  provided that no such amendment or waiver shall,  unless signed by all the
Bridge Banks, (i) increase or decrease the Bridge  Commitment of any Bridge Bank
(except for a ratable  decrease in the Bridge  Commitments of all Bridge Banks),
amend  Section  2.10(d)  hereof or  subject  any Bridge  Bank to any  additional
obligation,  (ii) reduce the principal of or rate of interest on any Bridge Loan
or any  fees  hereunder,  (iii)  postpone  the date  fixed  for any  payment  of
principal of or interest on any Bridge Loan, any Bridge Reimbursement Obligation
or any fees hereunder or for termination of any Bridge Commitment (provided that
the Required Banks may extend the Bridge  Termination  Date from time to time up
to but no later than  September  30,  1996),  (iv) change the  percentage of the
Bridge  Commitments or of the aggregate  unpaid  principal  amount of the Bridge
Notes,  or the number of Bridge  Banks,  which shall be required  for the Bridge
Banks  or any of them  to take  any  action  under  this  Section  or any  other
provision of the Financing Documents,  (v) release any Subsidiary Guarantor from
the Subsidiary  Guarantee  Agreement,  (vi) amend Section 8.04 or 8.06 hereof or
(vii)  notwithstanding any provision of any Collateral Document to the contrary,
release  any  item of  Collateral  from  the  Lien  provided  by the  Collateral
Documents except for the sale or other  disposition of such item by the Agent in
the exercise of its rights as provided therein (provided that unless an Event of
Default has occurred and is continuing,  the Agent may release any Collateral at
the request of the Borrower, without the consent of each of the Bridge Banks, if
(i) such  release  is  required  in  connection  with any  sale,  lease or other
disposition of such Collateral and (ii) such sale, lease or other disposition is
in  accordance  with  and  permitted  by the  terms  hereof  (including  without
limitation Sections 2.10(b)(i) and 5.12(b)) and of the Credit Agreement).

                  SECTION 8.06.  Successors  and Assigns.  (a) The provisions of
this  Agreement  shall be binding  upon and inure to the  benefit of the parties
hereto and their respective successors and assigns, except that the Borrower may
not assign or otherwise  transfer any of its rights under this Agreement without
the prior written consent of all Bridge Banks.

                  (b) Any Bridge Bank may at any time grant to one bank or other
institution (a "Participant") a participating  interest in its Bridge Commitment
and its Bridge Loans in the full amount of its Bridge  Commitment.  In the event
of any such grant by a Bridge Bank of a participating interest to a Participant,
whether or not upon notice to the Borrower and the Agent, such Bridge Bank shall
remain  responsible for the performance of its  obligations  hereunder,  and the
Borrower  and the Agent shall  continue to deal  solely and  directly  with such
Bridge Bank in connection with such Bridge Bank's rights and  obligations  under
this Agreement. Any agreement pursuant to which any Bridge Bank may grant such a
participating interest shall provide that such Bridge Bank shall retain the sole
right and  responsibility  to enforce the obligations of the Borrower  hereunder
including, without limitation, the right to approve any amendment,  modification
or waiver of any provision of this Agreement;  provided that such  participation
agreement may provide that such Bridge Bank will not agree to any  modification,
amendment or waiver of this Agreement  described in clause (i), (ii) or (iii) of
Section  8.05 without the consent of the  Participant.  An  assignment  or other
transfer  which is not permitted by  subsection  (c) or (d) below shall be given
effect for  purposes  of this  Agreement  only to the extent of a  participating
interest granted in accordance with this subsection (b).

                  (c)  Any  Bridge   Bank  may  assign  to  one  bank  or  other
institution  (each an "Assignee") all of its rights and  obligations  under this
Agreement  and the Bridge Notes and such  Assignee  shall assume such rights and
obligations, pursuant to an Assignment and Assumption Agreement in substantially
the form of  Exhibit K hereto  executed  by such  Assignee  and such  transferor
Bridge Bank, with (and subject to) the subscribed consent of the Borrower (which
shall not be unreasonably  withheld) and the Agent; provided that if an Assignee
is an affiliate of such  transferor  Bridge Bank or another Bridge Bank, no such
consent shall be required.  Upon  execution and delivery of such  instrument and
payment by such  Assignee to such  transferor  Bridge Bank of an amount equal to
the purchase  price  agreed  between such  transferor  ...  Bridge Bank and such
Assignee, such Assignee shall be a Bridge Bank party to this Agreement and shall
have all the rights and obligations of a Bridge Bank with a Bridge Commitment as
set forth in such instrument of assumption, and the transferor Bridge Bank shall
be released from its  obligations  hereunder to a corresponding  extent,  and no
further consent or action by any party shall be required.  Upon the consummation
of any assignment  pursuant to this subsection (c), the transferor  Bridge Bank,
the Agent and the  Borrower  shall make  appropriate  arrangements  so that,  if
required,  a new Bridge Note is issued to the Assignee.  In connection  with any
such  assignment,  the  transferor  Bridge  Bank  shall  pay  to  the  Agent  an
administrative fee for processing such assignment in the amount of $2,500.

                  (d) Any Bridge  Bank may at any time assign all or any portion
of its rights  under this  Agreement  and its Bridge  Note to a Federal  Reserve
Bank.  No such  assignment  shall  release the  transferor  Bridge Bank from its
obligations hereunder.

                  SECTION  8.07.  Certain  Collateral.  Each of the Bridge Banks
represents to the Agent and each of the other Bridge Banks that it in good faith
is not  relying  upon  any  "margin  stock"  (as  defined  in  Regulation  U) as
collateral in the extension or  maintenance  of the credit  provided for in this
Agreement.

                  SECTION 8.08. Governing Law; Submission to Jurisdiction.  This
Agreement  and each  Bridge  Note  shall be  construed  in  accordance  with and
governed by the law of the State of New York. The Borrower hereby submits to the
nonexclusive  jurisdiction  of the United States District Court for the Southern
District  of New York and of any New York State  court  sitting in New York City
for  purposes  of all  legal  proceedings  arising  out of or  relating  to this
Agreement or the  transactions  contemplated  hereby.  The Borrower  irrevocably
waives,  to the fullest extent  permitted by law, any objection which it may now
or hereafter have to the laying of the venue of any such  proceeding  brought in
such a court and any claim that any such proceeding  brought in such a court has
been brought in an inconvenient forum.

                  SECTION 8.09. Counterparts; Integration. This Agreement 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.  This Agreement  constitutes the entire agreement and  understanding
among  the  parties  hereto  and  supersedes  any and all prior  agreements  and
understandings, oral or written, relating to the subject matter hereof.

                  SECTION 8.10. WAIVER OF JURY TRIAL. EACH OF THE OBLIGORS,  THE
AGENT AND THE BRIDGE BANKS HEREBY  IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL
BY JURY IN ANY LEGAL PROCEEDING  ARISING OUT OF OR RELATING TO THIS AGREEMENT OR
THE TRANSACTIONS CONTEMPLATED HEREBY.

                  SECTION 8.11.  Reduced  Return.  If any Bridge Bank shall have
determined that, after the date hereof, the adoption of any applicable law, rule
or regulation regarding capital adequacy, or any change in any such law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental  authority,  central  bank or  comparable  agency  charged with the
interpretation or administration  thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable  agency, has or would have the effect of reducing the
rate of return on capital of such Bridge  Bank (or its Parent) as a  consequence
of such Bridge  Bank's  obligations  hereunder  to a level below that which such
Bridge Bank (or its Parent) could have achieved but for such  adoption,  change,
request or directive  (taking into  consideration  its policies  with respect to
capital  adequacy) by an amount deemed by such Bridge Bank to be material,  then
from time to time,  within 15 days after demand by such Bridge Bank (with a copy
to the Agent), the Borrower shall pay to such Bridge Bank such additional amount
or  amounts  as will  compensate  such  Bridge  Bank  (or its  Parent)  for such
reduction.  Each Bridge Bank will promptly  notify the Borrower and the Agent of
any event of which it has knowledge, occurring after the date hereof, which will
entitle such Bridge Bank to compensation pursuant to this Section. A certificate
of any Bridge Bank  claiming  compensation  under this Section and setting forth
the additional  amount or amounts to be paid to it hereunder shall be conclusive
in the absence of manifest error. In determining  such amount,  such Bridge Bank
may use any reasonable averaging and attribution methods.

                  SECTION 8.12. Other Reimbursement  Obligations.  The execution
of  this  Agreement  and any  other  documents,  agreements  or  instruments  in
connection  herewith  does not  constitute  a waiver or amendment of any term or
condition of any documents,  agreements or  instruments  evidencing or otherwise
delivered in connection  with the Other  Reimbursement  Obligations or the Other
Mortgage/Lease  Obligations.  No Bridge  Bank or Bank (as  defined in the Credit
Agreement)  shall  have any  rights or  obligations  under  any such  documents,
agreements or instruments unless party thereto and as set forth therein. Nothing
in any  Financing  Documents  requires  any  Bridge  Bank or Bank to obtain  any
consent from any other Bridge Bank or any other Bank in taking actions permitted
to be taken in  accordance  with the  terms  and  conditions  of any  documents,
agreements or instruments  evidencing or otherwise  delivered in connection with
the Other Reimbursement Obligations or Other Mortgage/Lease Obligations to which
it is a party, or in omitting to take any such actions.

                  SECTION  8.13.  Subordinate  Mortgages.  (a) Harris  Trust and
Savings Bank hereby  consent to the execution,  delivery and  recordation of the
Mortgage  relating to the Mortgaged  Facility  described as Item 12 in Part I of
Schedule III.

                  (b) Comerica Bank hereby  consents to the execution,  delivery
and recordation of the Mortgage relating to the Mortgaged  Facility described as
Item 15 in Part I of Schedule III.



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