ITEM 2.   ACQUISITION AND DISPOSITION OF ASSETS

     In July 1995, the registrant committed to dispose of its Transit segment
and on October 17, 1995, the registrant reached an agreement to transfer
substantially all of the assets and certain liabilities of its Transit segment
to American Passenger Rail Car Company, L.L.C. ("Amerail") a newly-formed
company wholly owned by persons not affiliated with the registrant. The
consideration for the disposition included the payment by Amerail of $42.1
million, borrowed by Amerail under new financing extended by banks, to pay off
the registrant's interim financing facilities for the Transit segment entered
into as of July 31, 1995 and the assumption of certain liabilities of the
Transit segment including its performance obligations for its major transit car
manufacturing and remanufacturing contracts. The guarantee by the registrant of
Amerail's reimbursement obligations does not allow this transfer to be treated
as a divestiture for accounting purposes according to SAB 5E, however this
transfer does represent an abandonment of the Transit segment by the registrant.
In accordance with SAB 93 the transfer will be accounted for as a discontinued
business. See the Asset Purchase Agreement which is filed as Exhibit 10.1 and is
incorporated herein by reference.

ITEM 5.   OTHER MATERIAL IMPORTANT EVENTS.

(a)  FINANCIAL RESTRUCTURING EVENTS.

     In connection with the transfer of the Transit segment (described above),
the two interim financing facilities established as of July 31, 1995 to fund the
operations of the Transit segment pending its disposition were paid off and
terminated on October 17, 1995. In addition, on October 10, 1995, the registrant
entered into amendments to its existing credit facilities to reflect the
disposition of the Transit segment and to reduce the maximum secured borrowing
amount under the bridge loan from $129 million to $100 million. See the Amended
and Restated Override Agreement and the First Amendment to Amended and Restated
Credit Agreement which are filed as Exhibits 4.1 and 4.2, each of which is
incorporated herein by this reference.

     As part of the disposition of the Transit segment, the registrant's primary
reimbursement obligations to certain banks with respect to the standby letter of
credit supporting the performance of the Transit segment's new transit car
manufacturing and remanufacturing contract with Metra was replaced with the
registrant's guaranty of Amerail's reimbursement obligations to the same bank
group under a replacement letter of credit and a new revolving credit facility
in the aggregate amount of $141 million provided by such banks to Amerail to
support its performance of the Metra contract. See the Guaranty which is filed
as Exhibit 4.4 and is incorporated herein by reference.

     In connection with the disposition of the Transit segment, the registrant
entered into a Reimbursement Agreement with its bonding company pursuant to
which the reimbursement obligations of the registrant to its bonding company for
the bonding company's losses on its payment and performance bonds supporting
certain non-Metra transit contracts (certain Transit contracts other than the
Metra contract) and certain secured financing to be provided to Amerail to
finance completion of such contracts were capped at approximately $31 million.
See the Reimbursement Agreement which is filed as Exhibit 4.3 and is
incorporated herein by reference.

(b)  SALE OF NORTH PACIFIC OPERATIONS.

     On September 22, 1995, the registrant completed the sale of its North
Pacific Operations to Tutor-Saliba Corporation for $17.1 million in cash. See
the Stock Purchase Agreement which is filed as Exhibit 10.2 and is incorporated
herein by this reference.

                         SATISFACTION OF THE BORROWERS'
                      OBLIGATIONS UNDER EXISTING AGREEMENTS

     2.1. ACKNOWLEDGEMENT OF OBLIGATIONS.  The Borrowers agree and acknowledge
that, as of July 1, 1995, they were obligated to the respective Existing Lenders
under their respective Existing Agreements in the amount of each such Existing
Lender's Initial Exposure.

     2.2. CONVERSION OF CONTINGENT TO FUNDED OBLIGATION.  Upon the occurrence of
a Conversion Event, the amount of the relevant Existing Lender's Existing Loans
shall be increased by the amount of the Liquidated Contingent Liability arising
by reason of such Conversion Event, and the amount of such Existing Lender's
Existing Contingent Indebtedness shall be decreased by a like amount.

     2.3. MATURITY OF EXISTING INDEBTEDNESS; TERMINATION DATE.  Each Existing
Loan and all other Obligations with respect to which a Conversion Event shall
have then occurred shall mature, and the principal amount thereof shall be due
and payable, on the Termination Date notwithstanding any earlier maturity date
or termination date in the Existing Agreements as in effect immediately prior to
the Original Closing Date.  Any obligation of either Borrower or any Guarantor

<PAGE>

than as required by SECTION 2.11.  On the Termination Date, the Agent on behalf

Metra Guaranty be prepaid or cash collateralized as required pursuant to the
terms of the applicable Existing Agreements as in effect immediately prior to
the Original Closing Date or, with respect to the Metra Guaranty, the Closing
Date, by delivering such prepayment or cash collateral to the Collateral Agent.
On the Termination Date, the Agent may demand payment in full of all Existing
Loans and take any other action as provided in ARTICLE IX.  Nothing in this
Agreement or any of the other Restructuring Documents, shall restrict or impair
any Existing Lender's right to seek recovery of Existing Contingent Indebtedness
or Obligations under the Metra Credit Agreement, and interest, fees and other
amounts payable in respect thereof from any Person other than the Borrowers and
the Guarantors.

     2.4. DEFERRED PAYMENTS AND AMORTIZATION.

          (a)  Subject to the terms of this Agreement, each Existing Lender
agrees to defer payment of all unpaid principal due under its Existing
Agreements from July 1, 1995, until the Termination Date, except pursuant to
SECTION 2.4(b).

          (b)  On September 30, 1996, the Borrowers shall pay to the Agent for
the benefit of the Existing Lenders in respect of the then unpaid amount of
their Existing Indebtedness, an amount equal to $100,000,000 plus interest and
fees accrued on Existing Loans as of such date, plus interest, fees and other
charges then accrued and unpaid under the Metra Guaranty to the extent necessary
to achieve and maintain Equilibrium.  Such payment shall be paid to the Agent
for the benefit of the Existing Lenders, shall be payable to each Existing
Lender in an amount equal to such Existing Lender's Pro Rata Share of such
payment as provided in SECTION 2.11, and applied to the Obligations as provided
in SECTION 2.10.

     2.5. INTEREST RATES; DEFERRAL OF INTEREST AND LETTER OF CREDIT FEES.

          (a)  Except as provided in SECTION 2.5(b), each Existing Loan shall
bear interest on the outstanding principal amount thereof, for each day after
July 1, 1995 until it becomes due, at a rate per annum equal to the Prime Rate;
PROVIDED, HOWEVER, that interest owing on Existing Loans which arise by reason
of a Conversion Event shall begin to accrue as of the date of such Conversion
Event.  The Borrowers agree that to the extent the Agent is required to
distribute payments into the Metra Holdback, as provided in SECTION 2.11(a), to
achieve and maintain Equilibrium, the Borrowers shall pay additional amounts to
the Agent to insure full payment of the amounts required to be paid to the Non-
Metra Lenders under SECTION 2.11(a) and this SECTION 2.5(a).  Deferred Interest
shall be paid as set forth in


                                       23
<PAGE>

SECTION 2.6.  The Deferred Interest accruing during each calendar month shall be
calculated as of the last day of such calendar month and interest on such amount
shall begin to accrue on the first day of the following calendar month.
Interest on Existing Loans, Facility Fees and Letter of Credit Fees accruing
after the Deferral Period until the Termination Date shall be payable on the
last day of each calendar month and on the Termination Date.  Except as provided
in SECTION 2.5(b), interest shall accrue on the Deferred Interest at a rate per
annum equal to the Prime Rate and during the Deferral Period shall be added to
the Deferred Interest.  Letter of Credit Fees and Facility Fees shall accrue in
the amounts provided under the applicable Existing Agreements.  Letter of Credit
Fees with respect to the NYCTA/PB Letters of Credit shall be paid directly to
the respective issuers thereof.  Interest, fees and other charges accruing under
the Metra Guaranty shall be payable hereunder only to the extent necessary to
achieve and maintain Equilibrium at the time of any payment to the Non-Metra
Lenders.

          (b)  Any Letter of Credit Fees, Facility Fees, principal of or
interest on any Existing Loan, any Deferred Interest and interest thereon and
any other amounts payable hereunder (including sums necessary to achieve
Equilibrium as more particularly described in the second sentence of SECTION
2.5(a)) not paid in the time specified in this Agreement (or to the extent
applicable, the Existing Agreement) shall bear interest, payable on demand, for
each day until paid at a rate per annum equal to the Default Rate.  In addition,
from and after the occurrence of any Event of Default (including any Event of
Default resulting from the filing of a bankruptcy case) and continuing until
such Event of Default is cured or has been waived in writing in accordance with
the terms of this Agreement, interest shall accrue on all Existing Loans at the
Default Rate and shall be payable on demand.  Any interest, reasonable
professional fees and expenses of the Agent and the Collateral Agent, or other
reasonable professional fees, expenses and charges of the Steering Committee
Lenders due under SECTION 12.4, which are not paid as and when due, shall bear
interest at the Default Rate and be payable on demand.  The interest rate
increase shall take effect immediately upon the occurrence of an Event of
Default, without prior notice to the Borrowers.

          (c)  For the purposes of calculating interest owing under an Existing
Agreement which constitutes a Contingent Obligation, such interest shall at all
times be deemed to accrue on unpaid principal at the rate at which interest is
then accruing with respect to Existing Loans.  In no event shall interest be
deemed to have accrued with respect to the unfunded principal portion of any
Obligation.

     2.6. PAYMENT OF DEFERRED INTEREST.  The Deferred Interest shall be repaid
in six equal monthly installments, together with interest accruing on the unpaid
amount thereof, on the last day of each calendar month commencing on April 30,
1996 (unless such


                                       24
<PAGE>

Deferred Interest has been repaid pursuant to a prepayment as provided in
SECTION 2.8 and SECTION 2.9).  Each such payment shall be paid to the Agent for
the benefit of the Existing Lenders, shall be payable to each Existing Lender in
an amount equal to such Existing Lender's Pro Rata Share of the Deferred
Interest as provided in SECTION 2.11.

     2.7. FEES.

          (a)  THE AGENT'S FEE.  The Borrowers shall pay to the Agent a non-
refundable monthly fee on the first day of each month in advance, in an amount
equal to $30,000 per month (the "Agent's Fee"), commencing the date the
obligations under the Bridge Loan Agreement are paid in full until such time as
the Borrowers and the Agent have no obligations under this Agreement and the
other Loan Documents (other than the Warrants).  The obligation to pay the
Agent's Fee shall survive the payment in full of the Obligations under this
Agreement.

          (b)  THE COLLATERAL AGENT'S FEE.  The Borrowers shall pay to the
Collateral Agent a non-refundable monthly fee on the first day of each month in
advance, in an amount equal to $30,000 per month (the "Collateral Agent's Fee"),
commencing the date the obligations under the Bridge Loan Agreement are paid in
full until such time as the Borrowers and the Collateral Agent have no
obligations under this Agreement and the other Loan Documents (other than the
Warrants).  The obligation to pay the Collateral Agent's Fee shall survive the
payment in full of the Obligations under this Agreement.

          (c)  FEES CUMULATIVE.  All fees payable under this Agreement shall be
cumulative, and fully earned on the date such payment is due.

     2.8. OPTIONAL PREPAYMENTS.

          (a)  Subject to the terms and conditions of the Intercreditor
Agreement and the Distribution Agreement, the Borrowers may, upon at least one
Business Day's notice to the Agent, prepay all or any portion of the
Obligations, in each case in whole at any time, or from time to time in part in
amounts aggregating $1,000,000 or any larger multiple of $1,000,000.  Each such
optional prepayment shall be paid to the Agent for the benefit of the Existing
Lenders, shall be payable to the Existing Lenders as provided in SECTION 2.11
and applied to the Obligations as provided in SECTION 2.10.

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


                                       25
<PAGE>

     2.9. MANDATORY PREPAYMENT.  Subject to the terms and conditions of the
Intercreditor Agreement, the Borrowers shall make prepayments as provided in
this SECTION 2.9.  Each such prepayment shall be paid to the Agent for the
benefit of the Existing Lenders, shall be payable to the Existing Lenders as
provided in SECTION 2.11 and applied to the Obligations as provided in
SECTION 2.10.

          (a)  Immediately upon receipt by any Borrower or any Consolidated
Subsidiary (other than Emkay Development Company, Inc.) or the Agent of (i) Net

sales in the ordinary course of business, sales under SECTION 8.4(ii), (iii),
(iv) and (v) or sales of equipment which are promptly replaced), (ii) Net Cash
Proceeds of any issuance of capital stock by the Borrowers or (iii) insurance
proceeds, the Borrowers shall pay or cause to be paid such Net Cash Proceeds or
insurance proceeds to the Agent on account of the Obligations for the benefit of
Existing Lenders; PROVIDED, HOWEVER, that so long as no Event of Default exists
and is continuing at the time such proceeds are received and unless otherwise
set forth in the Security Documents, (x) the Borrowers may retain up to an
aggregate amount of $1,000,000 of insurance proceeds to rebuild or replace
insured property destroyed or damaged, if such property is capable of being
rebuilt or replaced within a reasonable period of time, (y) the Borrowers may

between MKD and Morrison Knudsen Engenharia S.A. dated __________, 1995 in
substantially the form attached hereto as Schedule 2.9.

          (b)  Immediately upon receipt by the Borrowers of any repayment or

Section 4.5 of the Collateral Agent Agreement) as follows (regardless of how
each Existing Lender may treat such payments for purposes of its own


                                       26
<PAGE>


accounting):  FIRST to interest on Deferred Interest (to the extent then due);
SECOND to then due Letter of Credit Fees and interest on the Existing Loans
(other than Deferred Interest) accrued and unpaid prior to the date such funds
are received by the Existing Lenders; THIRD to Deferred Interest (to the extent
then due); and FOURTH to the unpaid principal amount of the Obligations.
Subject to the requirements of SECTION 2.11(b), sums payable to any of the Metra
Lenders hereunder shall be paid to the Metra Agent for the account of the Metra
Lenders and for distribution and application in accordance with the terms of the
Metra Credit Agreement.

     2.11.     GENERAL PROVISIONS AS TO PAYMENTS.

          (a)  The Borrowers shall make each payment of principal of, and
interest on, the Existing Loans and of fees and of all other Obligations (other
than Obligations payable under the Cash Management System and Letter of Credit
Fees with respect to the NYCTA/PB Letters of Credit), not later than 12:00 Noon
(Pittsburgh, Pennsylvania time) on the date when due, in Federal or other funds
immediately available in Pittsburgh, Pennsylvania, to the Agent at its address
referred to in the Schedule for Notices.  Subject to the provisions of this
SECTION 2.11, the Agent will promptly distribute each payment received by it on
account of the Obligations, FIRST, to the Agent on account of then due and
outstanding fees and expenses or other charges of the Agent or the Collateral
Agent under this Agreement or any of the other Loan Documents to the extent
payable by the Borrowers; SECOND, ratably in accordance with their Pro Rata
Shares, either to the Non-Metra Lenders or the Metra Lenders to the extent
required to achieve Equilibrium; THIRD, ratably to all Existing Lenders in
accordance with their Pro Rata Shares; and, FOURTH, to all other Obligations.
The Borrowers agree to pay to the Agent, upon demand, the amount of any payment
received by the Agent pursuant to the terms of the Cash Management System that
is subsequently returned to any bank that has transferred funds to the
Concentration Account in accordance with the Cash Management System, because
such bank transferred funds in advance of final collection and such funds are
not finally collected.  If such payment has already been applied in accordance
with SECTION 2.10 and is not paid by the Borrowers within one (1) Business Day
after the Agent's demand therefor, then each Existing Lender shall pay to the
Agent the share of such returned payment that it received and the Agent may
direct the Collateral Agent to disburse the share of such returned payment
deposited in the Contingent Indebtedness Account to the Agent.  Upon receipt by
the Agent of any such payment from the Borrowers, or from the Existing Lenders
and the Contingent Indebtedness Account in the event the Borrowers fail to make
such payment after the Agent's demand, the Agent shall pay such funds to Bank of
America Illinois, Bank of America National Trust and Savings Association or Key
Bank of Idaho, as appropriate, in such bank's capacity as a Deposit Bank in
order to pay the bank that transferred funds that were not finally collected and
the Borrowers' Obligations


                                       27
<PAGE>

shall be reinstated to the extent the Agent makes such payment.  The Agent's
determination of each Existing Lender's share of a returned payment received or
deposited in the Contingent Indebtedness Account shall be conclusive absent
manifest error.  Whenever any payment in respect of the Obligations 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)  The Agent shall make the distributions on account of the Existing
Contingent Indebtedness and, prior to the Metra Final Accounting Date, the Metra
Guaranty into an account established pursuant to SECTION 6.1 of the Collateral
Agent Agreement (the "Contingent Indebtedness Account").  From and after the
Metra Final Accounting Date, sums payable to any Metra Lender hereunder shall be
paid to the Metra Agent for distribution under the Metra Credit Agreement.
Funds distributed to the Non-Metra Lenders pursuant to SECTION 2.11(a) shall be
distributed, FIRST, ratably to each Non-Metra Lender in accordance with its
share of interest on the Deferred Interest; SECOND, to the extent of any
remaining balance, ratably to each Non-Metra Lender in accordance with its share
of the then due Letter of Credit Fees and interest on the Existing Loans (other
than Deferred Interest) accrued and unpaid prior to the date such funds are
received by the Non-Metra Lenders; THIRD, to the extent of any remaining
balance, ratably to each Non-Metra Lender in accordance with its share of the
Deferred Interest (to the extent then due); and FOURTH, to the extent of any
remaining balance, ratably to each Non-Metra Lender in accordance with its Pro
Rata Share for application to the unpaid principal amount of the Obligations.

          (c)  In the event that Conversion Events have occurred with respect to
Existing Contingent Indebtedness since the date of the last Recalculation, the
Agent shall request the Collateral Agent to disburse funds from the Contingent
Indebtedness Account to the Agent for distribution to each holder of Existing
Contingent Indebtedness for which such a Conversion Event has occurred, to the
extent necessary to provide that each such holder shall receive cash bearing the
same proportion to the amount of Existing Contingent Indebtedness that shall
have become Existing Loans at such time as the proportion that the aggregate
amount of all principal payments made under this Agreement with respect to any
Existing Loans outstanding July 1, 1995 bears to the outstanding principal
amount of such Existing Loans as of July 1, 1995.  In the event a Conversion
Event occurs with respect to the Metra Obligations, and the Metra Exposure
Percentage (calculated, for the purposes of this SECTION 2.11(c), as if the
Metra Holdback is zero) then exceeds the Non-Metra Exposure Percentage, then the
Agent will instruct the Collateral Agent to disburse funds from the Contingent
Indebtedness Account to the Agent for distribution to the Metra Agent for the
benefit


                                       28
<PAGE>

of the Metra Lenders in such amount sufficient to achieve Equilibrium
(calculated, for the purposes of this SECTION 2.11(c), as if the Metra Holdback
is zero).  In the event that either (i) funds remain in the Metra Holdback after
the disbursement described in the preceding sentence or (ii) following a
Conversion Event with respect to the Metra Obligations, the Non-Metra Exposure
Percentage then equals or exceeds the Metra Exposure Percentage (calculated, for
the purposes of this SECTION 2.11(c), as if the Metra Holdback is zero), then
the Agent shall request that the Collateral Agent deliver the balance then held
in the Metra Holdback to the Agent and the Agent shall promptly distribute such
amount in the same manner as if it were a new payment to be distributed pursuant
to this SECTION 2.11, including making a distribution to the Contingent
Indebtedness Account on account of the Existing Contingent Indebtedness and, to
the extent then so required, to the Metra Lenders on account of the Metra
Obligations.

          (d)  If any Reductions in Liability shall occur at any time with
respect to any Existing Contingent Indebtedness, the Agent shall request the
Collateral Agent to disburse excess funds which may have arisen in the
Contingent Indebtedness Account as follows:  FIRST, the Agent shall calculate
the percentage that (i) the aggregate amount of all principal payments paid
under this Agreement with respect to any Existing Loans outstanding on July 1,
1995 bears to (ii) the outstanding principal amount of such Existing Loans as of
July 1, 1995; SECOND, the Agent shall determine the amount of funds that should
remain in the Contingent Indebtedness Account by multiplying such percentage by
the aggregate principal amount of all Existing Contingent Indebtedness
immediately after giving effect to any such Reduction in Liability; and THIRD,
to the extent that the amount of funds on deposit in the Contingent Indebtedness
Account exceeds the amount that should remain on deposit, as so determined by
the Agent, the Agent shall request that the Collateral Agent deliver such excess
to the Agent and the Agent shall promptly distribute such amount in the same
manner as if it were a new payment to be distributed pursuant to this
SECTION 2.11, including making a distribution to the Contingent Indebtedness
Account on account of the Existing Contingent Indebtedness and, to the extent
then required, to the Metra Lenders on account of the Metra Obligations.  Upon
the occurrence of each Reduction in Liability with respect to the Metra
Obligations the Agent shall request the Collateral Agent to disburse from the
Metra Holdback the lesser of (i) the entire balance of the Metra Holdback and
(ii) an amount necessary to achieve Equilibrium (by the resulting increase in
the Metra Exposure Percentage).  The Agent shall promptly distribute funds so
disbursed in the same manner as if it were a new payment to be distributed
pursuant to this SECTION 2.11, including making a distribution to the Contingent
Indebtedness Account on account of the Existing Contingent Indebtedness and, to
the extent then required, to the Metra Lenders on account of the Metra
Obligations.


                                       29
<PAGE>

          (e)  Except as set forth in SECTION 2.11(c) and SECTION 2.11(f), funds
that would otherwise have been distributed to the Metra Agent for the benefit of
the Metra Lenders pursuant to SECTIONS 2.11(b), 2.11(c) and 2.11(d) shall remain
in the Contingent Indebtedness Account (the "Metra Holdback") until the Metra
Final Accounting Date.

          (f)  If eight years after the Termination Date, no Event of Default
under SECTION 9.1(f) or 9.1(g) has occurred and funds remain in the Contingent
Indebtedness Account, the Agent shall distribute to each Existing Lender its Pro
Rata Share of the Contingent Indebtedness Account; PROVIDED, that for the
purposes of determining each Existing Lender's Pro Rata Share under this
SECTION 2.11(f), only Existing Loans or other Obligations with respect to which
a Conversion Event has occurred shall be included in the calculation of each
Existing Lender's Exposure and the Aggregate Exposure, unless all Existing Loans
and all other Obligations with respect to which a Conversion Event has occurred
have been paid in full, in which case, the Agent shall distribute to each
Existing Lender holding Existing Contingent Indebtedness and Metra Obligations
(if the Metra Final Accounting Date has not occurred) its Pro Rata Share of the
Contingent Indebtedness Account.  Any distribution to Existing Lenders on
account of the Metra Obligations or Existing Contingent Indebtedness shall be
held by such Existing Lender as cash collateral and applied to such Obligations
upon maturity.

     2.12.     RECALCULATION.  On the Original Closing Date and on the first day
of each calendar quarter, commencing with the calendar quarter beginning
October 1, 1995, at such other times as may be requested by the Majority Lenders
or the Metra Agent, and at such other time or times as Agent may deem
appropriate for the purposes of determining distributions, voting, or any other
act under this Agreement to which each Existing Lender's Pro Rata Share may be
relevant, the Agent shall recalculate (a "Recalculation") each Existing Lender's
Existing Contingent Indebtedness, Existing Loans and Metra Obligations on the
basis of Reallocation Certificates most recently submitted pursuant to SECTION
2.13 to determine the amount of each such Existing Lender's Exposure as of each
such date (the "Periodic Exposure").  For purposes of voting and of making
distributions pursuant to SECTION 2.11, the Agent shall use the Pro Rata Shares
and Pro Rata Shares of Deferred Interest determined as of the Original Closing
Date until the next Recalculation, and thereafter the Agent shall use the Pro
Rata Shares and Pro Rata Shares of Deferred Interest determined as of the most
recent Recalculation.  In the event that any such Reallocation Certificate
states that any Reductions in Liabilities have occurred then the Agent shall:
(a) recalculate each Existing Lender's Pro Rata Share; (b) indicate to each
Existing Lender who shall have experienced Reductions in Liability, the amount,
if any, by which such Existing Lender has received distributions pursuant to
this Agreement in excess of the amount such Existing Lender would otherwise be
entitled to receive under this Agreement (calculated


                                       30
<PAGE>


other than for purposes of accruing interest and fees, as if such Reduction in
Liability had occurred before July 1, 1995) and the amount of Obligations, if
any, to be purchased by such Existing Lender pursuant to SECTION 12.5(b) by
reason of any Reductions of Liability (in which event such Existing Lender shall
promptly comply with its obligations under SECTION 12.5(b) of this Agreement);
and (c) comply with the Agent's obligations regarding the Contingent
Indebtedness Account as more particularly described in SECTION 2.11 above.  In
the event that any such Reallocation Certificate states that any Conversion
Events have occurred, then the Agent shall (a) determine the amount of interest
then due and payable on account of any Existing Loans which may have been
created by such Conversion Event and so advise the Borrowers and (b) comply with
the Agent's obligations regarding the Contingent Indebtedness Account as more
particularly described in SECTION 2.11 above.

     2.13.     DELIVERY OF REALLOCATION CERTIFICATES.  Five (5) Business Days
prior to the beginning of each calendar quarter, commencing with the calendar
quarter beginning October 1, 1995, each Existing Lender who is the holder of
Existing Loans or Existing Contingent Indebtedness shall deliver to the Agent a
current Reallocation Certificate, and the Metra Agent shall deliver to the Agent
a current Reallocation Certificate with respect to the Metra Obligations held by
each Metra Lender.  In addition to Reallocation Certificates required under the
first sentence of this Section, within five (5) Business Days after request by
the Agent, any Existing Lender or the Metra Agent, as the case may be, shall
deliver to the Agent a current Reallocation Certificate.  Each of the Existing
Lenders and the Metra Agent may, in its discretion and from time to time,
deliver to the Agent a current Reallocation Certification.  Should any Existing
Lender or the Metra Agent fail to comply with its obligations under this
SECTION 2.13 the Agent may withhold distribution of funds otherwise payable to
such Existing Lender or the Metra Agent, as the case may be, under this
Agreement until such Existing Lender or the Metra Agent has so complied.  If
such Existing Lender or the Metra Agent has not complied ninety (90) days after
written request from the Agent (including the Agent's initial request) and
forty-five (45) days after a second written request from the Agent, such
Existing Lender's Exposure, or, in the case of the Metra Agent, the Metra
Obligations, shall be deemed to be zero (0).

     2.14.     COMPUTATION OF INTEREST AND FEES.  Interest and 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).

     2.15.     CASH MANAGEMENT SYSTEM.  Each Borrower has established, on or
prior to the Original Closing Date, and each Borrower will maintain until the
Obligations have been paid in full, the Cash Management System described in

     2.16.     TAXES.

          (a)  Any and all payments by either Borrower to or for the account of
any Existing Lender or the Agent hereunder or any other Loan Document shall be
made without deduction for any Taxes or Other Taxes; PROVIDED, that if either
Borrower shall be required by law to deduct any Taxes or Other Taxes from any
such payments, (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 2.16) such Existing Lender 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) such Borrower shall make such deductions, (iii)
such Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law and (iv) such
Borrower shall furnish to the Agent, at its address referred to in the Schedule
for Notices, the original or a certified copy of a receipt evidencing payment
thereof.

          (b)  The Borrowers agree to indemnify each Existing Lender and the
Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other
Taxes imposed or asserted by any jurisdiction on amounts payable under this
SECTION 2.16) paid by such Existing Lender 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 Existing Lender or the Agent (as the case may be) makes demand therefor.

          (c)  Each Existing Lender 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 Existing Lender listed on the signature
pages hereof and on or prior to the date on which it becomes an Existing Lender
in the case of each other Existing Lender, and from time to time thereafter if
requested in writing by the Borrowers (but only so long as such Existing Lender
remains lawfully able to do so), shall provide the Borrowers with Internal
Revenue Service form 1001 or 4224, as appropriate, or any successor form
prescribed by the Internal Revenue Service, certifying that such Existing Lender
is entitled to benefits under an income tax treaty to which the United States is
a party which exempts the Existing Lender from United States withholding tax or
reduces the rate of withholding tax on payments of interest for the account of
such Existing Lender 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.

          (d)  For any period with respect to which an Existing Lender has
failed to provide the Borrowers with the appropriate form pursuant to
SECTION 2.16(c) (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


                                       32
<PAGE>

to be provided), such Existing Lender shall not be entitled to indemnification
under SECTION 2.16(b) or 2.16(c) with respect to Taxes imposed by the United
States on payments by such Borrower; PROVIDED, that if an Existing Lender, 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, such Borrower shall take such steps as such Existing Lender shall
reasonably request to assist such Existing Lender to recover such Taxes.

          (e)  If either Borrower is required to pay additional amounts to or
for the account of any Existing Lender pursuant to this SECTION 2.16, then such
Existing Lender will change the jurisdiction of its lending office to an office
it maintains if, in the judgment of such Existing Lender, such change (i) will
eliminate or reduce any such additional payment which may thereafter accrue and
(ii) is not otherwise disadvantageous to such Existing Lender.

Documents by the Borrowers or the


                                       33

                         REPRESENTATIONS AND WARRANTIES

          In order to induce the Agents and the Existing Lenders to enter into
this Agreement, the Borrowers hereby make the following representations and
warranties to the Agent and to each Existing Lender:

     6.1. ORGANIZATION AND QUALIFICATION.  Each of the Borrowers and the
Guarantors is a corporation duly organized, validly existing and in good
standing under the laws of the state of its incorporation and is duly qualified
and in good standing in each jurisdiction wherein the conduct of its business or
the ownership of its properties requires such qualification, except for those
jurisdictions in which the failure to be qualified and in good standing would
not have or result in a Material Adverse Effect or would not materially
adversely affect the ability of the Collateral Agent to collect any material
account receivable.

     6.2. CORPORATE POWER AND AUTHORIZATION; BINDING EFFECT.  Each of the
Borrowers and the Guarantors has the corporate power and has taken all corporate
action necessary to authorize it to execute, deliver, and perform this
Agreement, each of the other Restructuring Documents and the T-Co Asset Purchase
Documents, executed by it and to grant the security interests and liens granted
or created thereunder.  This Agreement constitutes, and when executed the other
Restructuring Documents and the T-Co Asset Purchase Documents, will constitute,
legal and valid obligations of each Borrower binding upon it and enforceable in
accordance with their respective terms, except as the enforceability of each
such Restructuring Document and T-Co Asset Purchase Document may be subject to

other similar laws relating to or affecting the rights of creditors and except
as the availability of equitable remedies are subject to the application of
equitable principles.

     6.3. NO CONFLICT.  The execution, delivery and performance of this
Agreement, the other Restructuring Documents and the secured financing
transactions contemplated hereby, and the T-Co Asset Purchase Documents, the use
of proceeds thereof, and the performance by the Borrowers and the Guarantors (a)
do not conflict with or violate any provision of the Articles of Incorporation
or Certificate of Incorporation, as the case may be, or By-Laws of any Borrower
or any Guarantor, any material Requirement of Law or any Contractual Obligation
of any Borrower or any Guarantor, (b) do not conflict with, constitute a default
or require any consent under any Contractual Obligation of any


                                       37
<PAGE>

Borrower or any Guarantor, and (c) do not result in the creation of any Lien
other than a Permitted Lien upon any property or assets of any Borrower or any
Guarantor.

     6.4. NO CONSENTS.  All necessary consents, approvals and authorizations of,
filings with, and acts by or with respect to all Governmental Authorities and
other Persons (except possession of certain collateral or filings with the
appropriate Governmental Authorities necessary to perfect the security interests
under the Security Documents) required to be obtained, made or taken by the
Borrowers or the Guarantors in connection with the secured financing
transactions contemplated hereby or with the execution, delivery, performance,
validity or enforceability of this Agreement, the other Restructuring Documents
or the T-Co Asset Purchase Documents, have been obtained, made or taken, and
remain in effect.  All applicable waiting periods have expired without any
Governmental Authority or other Person taking any action which restricts,
prevents or imposes materially adverse conditions upon the consummation of the
secured financing transactions contemplated hereby.

     6.5. ABSENCE OF LITIGATION.  Except as otherwise set forth in
SCHEDULE 5.1(c), there are no actions, suits, proceedings or other litigation
(including proceedings by or before any arbitrator or Governmental Authority)
pending, or, to the Borrowers' knowledge, threatened, against or affecting the
Borrowers or the Guarantors or any of their Consolidated Subsidiaries or, to the
knowledge of the Borrowers, any basis therefor, (a) which challenge the validity
or propriety of the secured financing transactions contemplated hereby, (b)
which could reasonably be expected to have or result in, individually or in the
aggregate, a Material Adverse Effect, or (c) which could materially affect the
ability of the Borrowers to perform their obligations under this Agreement or
the other Restructuring Documents.

     6.6. NO DEFAULT UNDER THE RESTRUCTURING DOCUMENTS.  No Default or Event of
Default has occurred and is continuing.

     6.7. INDEBTEDNESS.  Set forth on SCHEDULE 6.7A hereto is a complete and
correct list of all Indebtedness of the Borrowers and the Guarantors in excess
of $2,000,000, other than Contingent Obligations, and the approximate aggregate

and correct list of all Contingent Obligations for which the principal amount
outstanding or the amount for which the Borrowers or the Guarantors are liable
exceeds $1,000,000, and the approximate aggregate amount of such principal or of
such liability outstanding.

     6.8. MATERIAL CONTRACTS.  Set forth on SCHEDULE 6.8 hereto is a complete
and accurate list of (a) each Material Contract, and (b) each Capital Lease
Obligation of the Borrowers and the Guarantors existing on the Original Closing
Date which


                                       38
<PAGE>

exceeds $10,000,000 annually; other than as set forth in SCHEDULE 6.8 or
otherwise disclosed in writing to the Agent, each such Material Contract or
Capital Lease is, and after giving effect to the consummation of the
transactions contemplated by the T-Co Restructuring will be, in full force and
effect in accordance with the terms thereof.  Except as previously disclosed to
the Agent and the Existing Lenders or as listed in SCHEDULE 6.8A hereto, there
are no defaults by the Borrowers or the Guarantors or, to the best of their
knowledge, by any other party under any such Material Contract which could
reasonably be expected to have or result in a Material Adverse Effect, or could
reasonably be expected to affect the Borrowers' or the Guarantors' ability to
perform their Obligations under this Agreement and the other Restructuring
Documents and the T-Co Asset Purchase Documents.  Neither the Borrowers nor the
Guarantors are in default (nor has any event occurred which, with notice or
lapse of time or both would constitute a default) under any of the Existing
Agreements.  The Borrowers and the Guarantors have delivered to the Agent a true
and complete copy of each Material Contract required to be listed on
SCHEDULE 6.8.

described in Item No. 2.00 of the Schedule of Documents delivered in connection
with the July 31, 1995  Restructuring, and delivered to the Agent in connection

the Consolidated financial condition of the Borrowers, the Guarantors and their
Consolidated Subsidiaries as of the date thereof, (b) disclose all material
liabilities of the Borrowers, the Guarantors and their Consolidated
Subsidiaries, whether liquidated or unliquidated, fixed or contingent, that are
required to be disclosed under Generally Accepted Accounting Principles as of
the date thereof, and (c) have been prepared in accordance with Generally
Accepted Accounting Principles, consistently applied.  Each of the Budget and
the projections delivered to the Agent in connection herewith are based upon
reasonable estimates and assumptions, and reflect the reasonable estimates of
the Borrowers and their Consolidated Subsidiaries of the results of
operations and other information projected therein.

     6.11.     SECURITY DOCUMENTS.  The Security Documents to which the
Borrowers and the Guarantors are a party create in favor of the Collateral Agent
for the benefit of the Existing Lenders to secure the Obligations valid, and,

<PAGE>

     6.12.     TAXES.  The Borrowers and the Guarantors have filed all tax
returns which were required to be filed in any jurisdiction, and paid all taxes
shown thereon to be due or otherwise due upon the Borrowers and the Guarantors
or any of their properties, income or franchises, including interest,
assessments, fees and penalties (other than any immaterial amounts, which the
Borrowers or the Guarantors shall pay or make provision to pay), or have
provided adequate reserves for the payment thereof.  To the best knowledge of
the Borrowers, no claims are threatened, pending or being asserted with respect
to, or in connection with any return referred to in this SECTION 6.12, which
could reasonably be expected to have or result in a Material Adverse Effect, or
could reasonably be expected to affect the Borrowers' ability to perform their
Obligations under this Agreement and the other Restructuring Documents.

     6.13.     NO BURDENSOME RESTRICTIONS.  No Material Contract and no material
Requirement of Law relating to or otherwise affecting the Borrowers or the
Guarantors will result in a Material Adverse Effect.

     6.14.     JUDGMENTS.  There are no outstanding or unpaid judgments against
the Borrowers or the Guarantors in excess of (a) $100,000 individually, or
(b) $2,000,000 in the aggregate, except as expressly set forth in SCHEDULE 6.14.

     6.15.     COMPLIANCE WITH LAWS.  The Borrowers and the Guarantors are not
and will not be in violation of, or not in compliance with, any Requirement of
Law binding upon the Borrowers and the Guarantors or their properties and
assets, including any building, zoning, occupational safety and health
ordinances or regulations relating to their structure or equipment, or the
operation thereof or of its respective business, or any applicable fair
employment, equal opportunity or similar law, ordinance or regulation, the
noncompliance with which could reasonably be expected to have or result in a
Material Adverse Effect, and are not a party to any agreement or instrument, or
subject to any judgment, order, writ, rule, regulation, code or ordinance which
could reasonably be expected to have or result in a Material Adverse Effect.

     6.16.     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 Multi-employer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could reasonably result in the imposition of a Lien


                                       40
<PAGE>

or the posting of a bond or other security under ERISA or the Internal Revenue
Code or (iii) except as set forth on SCHEDULE 6.16, incurred any liability under
Title IV of ERISA other than a liability to the PBGC for premiums under
Section 4007 of ERISA.

     6.17.     GOVERNMENTAL AUTHORIZATIONS; PERMITS, LICENSES AND
ACCREDITATIONS; OTHER RIGHTs.  The Borrowers and the Guarantors have all
licenses, permits, approvals, qualifications, consents, certificates of needs
and accreditations (where such are required) and other authorizations necessary
for the lawful conduct of their respective businesses or operations wherever now
conducted and as planned to be conducted, pursuant to all applicable statutes,
laws, ordinances, rules and regulations of all Governmental Authorities having,
asserting or claiming jurisdiction over the Borrowers or the Guarantors, except
where such failure could not have or result in a Material Adverse Effect.
Copies of all such licenses, permits, approvals, qualifications, consents and
other authorizations shall be provided to the Agent upon request.  Neither the
Borrowers nor the Guarantors are in default under any of such licenses, permits,
approvals, consents, qualifications or authorizations and no event has occurred,
and no condition exists, which, with the giving of notice, the passage of time,
or both, would constitute a default thereunder or would result in the
suspension, revocation, impairment, forfeiture or non-renewal of any such
permit, license, authorization or accreditation, except where such failure could
not have or result in a Material Adverse Effect.  The continuation, validity and
effectiveness of all material licenses, permits, approvals, consents,
qualifications and authorizations will not be adversely affected by the
transactions contemplated by this Agreement.  The Borrowers know of no reason
why they or the Guarantors will not be able to maintain all licenses, permits,
approvals, consents, qualifications, accreditations and other authorizations
necessary or appropriate to own and operate their respective current businesses
and to obtain such licenses, permits, approvals, consents, qualifications and
other authorizations necessary to own and operate their respective current
businesses, and otherwise conduct the business of the Borrowers, the Guarantors
and their Consolidated Subsidiaries as now conducted and presently proposed to
be conducted.

     6.18.     ENVIRONMENTAL MATTERS.  In the ordinary course of their business,
the Borrowers conduct an ongoing review of the effect of Environmental Laws on
the business, operations and properties of the Borrowers, the Guarantors and
their Consolidated Subsidiaries, in the course of which they identify and
evaluate associated liabilities and costs (including any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or

representation or warranty by the Agent to any Existing Lender.  Each Existing
Lender represents to the Agent that, independently and without reliance upon the
Agent or any other Existing Lender and based on such documents and information
as it has deemed appropriate, it has made its own appraisal of and investigation
into the business, operations, property, financial and other condition and
creditworthiness of the Borrowers and has made its own decision to enter into
this Agreement.  Each Existing Lender also represents that, independently and
without reliance upon the Agent or any other Existing Lender, and based on such
documents and information as it deems appropriate at the time, it shall continue
to make its own credit analysis, appraisals and decisions in taking or not
taking action under this Agreement and the other Loan Documents and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrowers.  Except for notices, reports and other documents expressly required
to be furnished to the Existing Lenders by the Agent hereunder, the Agent shall
have no obligation or liability to provide any Existing Lender with any credit
or other information concerning the business, operations, property, financial
and other condition or creditworthiness of the Borrowers which may come into the
possession of either of the


                                       63
<PAGE>

Agent or any of their officers, directors, employees, agents, attorneys-in-fact
or affiliates.

     10.9.     COLLATERAL.  Each of the Existing Lenders represents to the Agent
and each of the other Existing Lenders 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.

     10.10.    INDEMNIFICATION.  Each of the Existing Lenders shall indemnify,
defend and hold harmless the Agent in its capacity as such (to the extent not
reimbursed by the Borrowers and without limiting the obligation of the Borrowers
to do so), ratably according to their Pro Rata Share as of date demand for
payment is made upon such Existing Lenders from and against any and all claims,
demands, lawsuits, costs, expenses, fees, liabilities, obligations, losses,
damages, actions, recoveries, judgments, suits, costs, expenses or disbursements
of any kind whatsoever, including interest, penalties and attorneys' fees and
costs, whether direct, indirect, consequential or incidental, which at any time
(including at any time following the payment of all amounts payable under the
Existing Agreements and the Restructuring Documents) may be imposed on, incurred
by or asserted against the Agent in its capacity as such and not in its
individual capacity in any way relating to, resulting from or arising out of
this Agreement, or the Restructuring Documents, the transactions contemplated
hereby or any action taken or omitted by the Agent under or in connection with
any of the foregoing; PROVIDED, HOWEVER, that no Existing Lender shall be liable
for the payment of any portion of such claims, demands, lawsuits, costs,
expenses, fees, liabilities, obligations, losses, damages, actions, remedies,
judgments, suits, costs, expenses or disbursements to the extent such result
from the Agent's gross negligence or willful misconduct.  The agreements in this
SECTION 10.10 shall survive the payment of all amounts payable under
Restructuring Documents and shall be in addition to and not in lieu of any other
indemnification agreements set forth in the Restructuring Documents.

     10.11.    THE AGENT IN ITS INDIVIDUAL CAPACITY.  The Agent in its
individual capacity, and its Affiliates, may make loans and other financial
accommodations to, accept deposits from and generally engage in any kind of
business with the Borrowers and their Subsidiaries as though the Agent was not
the Agent hereunder.  With respect to its Existing Indebtedness and any other
Indebtedness made or renewed by it, the Agent in its individual capacity shall
have the same benefits, rights, powers and privileges under this Agreement, and
the Loan Documents as any Existing Lender and may exercise the same as though it
were not the Agent, and the terms "Existing Lender" and "Existing Lenders" shall
include the Agent in its individual capacity.

     10.12.    THE SUCCESSOR AGENT.  The Agent may resign as such upon ten days'
prior written notice to the Existing Lenders.  The


                                       64
<PAGE>

Agent shall concurrently provide the Borrowers with a copy of such notice.  If
the Agent shall resign as such under this Agreement, then the Majority Lenders
shall appoint from among the Existing Lenders a successor agent for the Existing
Lenders.  A successor agent may also be appointed by the Majority Lenders if the
Agent ceases to have any Existing Indebtedness, and upon such appointment of a
successor agent the Agent shall resign as such.  Upon acceptance of its
appointment as the successor agent in writing, (a) such successor agent shall
succeed to the rights, powers, privileges and duties of the Agent as the case
may be, (b) the retiring Agent shall be discharged of all its obligations and
liabilities in such capacity under this Agreement, and the Loan Documents, (c)
the term "Agent" shall mean such successor agent effective upon its appointment,
and (d) the retiring Agent's rights, powers and duties as the Agent as the case
may be shall be terminated, without any other or further act or deed on the part
of such former Agent or any of the parties to this Agreement or their successors
and assigns.  With respect to any actions taken or omitted to be taken by the
retiring Agent while it was the Agent (for which retiring Agent may still have
liability), the retiring Agent shall continue to receive the benefits of this
ARTICLE X, including SECTION 10.10.

     10.13.    APPLICABILITY OF SECTION TO THE BORROWERS.  Notwithstanding any
other provision contained in this ARTICLE X, the rights and obligations of the
Borrowers under this Agreement shall not be affected by any provision otherwise
included in this ARTICLE X.  The Borrowers shall be permitted to rely on
communications from the Agent which it reasonably believes are made on behalf of
the Agent and, if specified therein, the Existing Lenders, and except as
otherwise set forth specifically herein, all notices and payments to be made by
the Borrowers hereunder shall be made to the Agent.  Further, if any Existing
Lender shall be in default hereunder, such default shall not affect the right
and obligations of the Borrowers hereunder.  The Agent shall provide the
Borrowers with prompt notice of any default by any Existing Lender.

     10.14.    DELIVERY TO THE AGENT OF EXISTING AGREEMENTS.  If requested by
the Agent in order to enforce any of the rights or remedies of the Existing
Lenders under the Loan Documents, each Existing Lender shall deliver to the
Agent the originals of any promissory notes or other Existing Agreements held by
such Existing Lender evidencing the Existing Indebtedness, and if requested by
the Agent from time to time for any other reason shall deliver to the Agent
copies of any such promissory notes or other Existing Agreements.

                                   ARTICLE XI

                           JOINT AND SEVERAL LIABILITY

     11.1.     JOINT AND SEVERAL LIABILITY.  Each Borrower agrees that such
Borrower is jointly and severally liable for the Obligations hereunder and that
all Obligations of each Borrower now or hereafter existing under this Agreement,
whether for principal, interest, fees, indemnification, expenses or other- wise,
will be paid strictly in accordance with the terms of this Agreement and the
other Restructuring Documents regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Agent or the Existing Lenders with respect thereto.  So long as
the Obligations have not been paid in full, the liability of each Borrower
hereunder shall be absolute and unconditional irrespective of:

          (a)  any taking, exchange, release, or nonperfection of any Collateral
or any release or amendment or waiver of or consent to departure from any
guaranty, for all or any of the Obligations; or

          (b)  any other circumstance which might otherwise constitute a defense
available to, or a discharge of, any Borrower.

     11.2.     THE GUARANTEES.  If and to the extent any Obligation of any
Borrower to the Agent or any Existing Lender shall be considered an obligation
of guaranty or suretyship, each Borrower hereby unconditionally guarantees the
full and punctual payment (whether at stated maturity, upon acceleration or
otherwise) of the Obligations.  Upon failure by either Borrower to pay
punctually any such amount, the other Borrower shall forthwith on demand pay the
amount not so paid at the place and in the manner specified in this Agreement.

     11.3.     GUARANTEES UNCONDITIONAL.  The Obligations of each Borrower
hereunder shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by:

          (a)  Any extension, renewal, settlement, compromise, waiver or release
in respect of any Obligation of the other Borrower under this Agreement, the
Existing Agreements, the other Restructuring Documents or by operation of law or
otherwise;

          (b)  Any modification or amendment of or supplement to this Agreement,
the Existing Agreements or the other Restructuring Documents;

          (c)  Any release, impairment, non-perfection or invalidity of any
direct or indirect security for any Obligation


                                       66
<PAGE>

of the other Borrower under this Agreement, the Existing Agreements or the other
Restructuring Documents;

          (d)  Any change in the corporate existence, structure or ownership of
the other Borrower, or any insolvency, bankruptcy, reorganization or other
similar proceeding affecting the other Borrower or its assets or any resulting
release or discharge of any Obligation of the other Borrower contained in this
Agreement, the Existing Agreements or the other Restructuring Documents;

          (e)  The existence of any claim, set-off or other rights which a
Borrower may have at any time against the other Borrower, the Agent, any
Existing Lender or any other Person, whether in connection herewith or any
unrelated transactions; PROVIDED, that nothing herein shall prevent the
assertion of any such claim by separate suit or compulsory counterclaim;

          (f)  Any invalidity or unenforceability relating to or against the
other Borrower for any reason of this Agreement, the Existing Agreements or the
other Restructuring Documents, or any provision of applicable law or regulation
purporting to prohibit the payment by the other Borrower of the principal,
interest or any other amount payable by it under this Agreement or the other
Restructuring Documents; or

          (g)  Any other act or omission to act or delay of any kind by the
other Borrower, the Agent, any Existing Lender or any other Person or any other
circumstance whatsoever which might, but for the provisions of this paragraph,
constitute a legal or equitable discharge of its Obligations under this
Agreement, the Existing Agreements or the other Restructuring Documents.

     11.4.     DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES.  The Borrowers' Obligations hereunder shall remain in full force
and effect until the Obligations have been paid in full.  If at any time any
payment of the principal of or interest on any Existing Indebtedness or any
other amount payable by a Borrower under this Agreement is rescinded or must be
otherwise restored or returned upon the insolvency, bankruptcy or reorganization
of a Borrower or otherwise, the other Borrower's Obligations hereunder with
respect to such payment shall be reinstated at such time as though such payment
had been due but not made at such time.

     11.5.     WAIVERS BY THE BORROWERS.  The following waivers shall apply to
the guarantees under this ARTICLE XI:

          (a)  EACH BORROWER EXPRESSLY WAIVES THE RIGHT TO REQUIRE THE AGENT,
THE COLLATERAL AGENT OR ANY EXISTING LENDER FIRST TO PURSUE THE OTHER BORROWER
OR ANY OTHER PERSON, THE COLLATERAL, OR ANY OTHER SECURITY OR GUARANTY THAT MAY
BE HELD FOR THE OBLIGATIONS, OR TO APPLY ANY SUCH SECURITY OR GUARANTY TO



                                       67
<PAGE>

THE OBLIGATIONS BEFORE SEEKING FROM SUCH BORROWER PAYMENT IN FULL OF ITS
OBLIGATIONS TO THE AGENT AND THE EXISTING LENDERS OR PROCEEDING AGAINST SUCH
BORROWER FOR SAME;

          (b)  EACH BORROWER ACKNOWLEDGES THAT:

               (i)  IF A DEFAULT OR EVENT OF DEFAULT OCCURS AND SUCH BORROWER
PAYS TO THE AGENT AND THE EXISTING LENDERS ALL OR PART OF THE OBLIGATIONS, SUCH
BORROWER WOULD HAVE A RIGHT TO PROCEED AGAINST THE OTHER BORROWER TO THE EXTENT
OF THE OBLIGATIONS SO PAID BY SUCH BORROWER AND TO HAVE THE BENEFIT OF ANY
SECURITY HELD BY THE AGENT OR COLLATERAL AGENT FOR THE OBLIGATIONS TO THE EXTENT
OF THE OBLIGATIONS SO PAID BY THE BORROWER.  SUCH RIGHT IS COMMONLY KNOWN AS THE
"RIGHT OF SUBROGATION."

               (ii) IF AN EVENT OF DEFAULT OCCURS, THE AGENT, AMONG OTHER
THINGS, MAY ENFORCE ANY LIEN UPON ANY INTEREST IN REAL PROPERTY ("REAL PROPERTY
LIEN") BY MEANS OF JUDICIAL ACTION OR BY NON-JUDICIAL ACTION COMMONLY KNOWN AS A
"NON-JUDICIAL FORECLOSURE," "TRUSTEE'S SALE" OR "POWER OF SALE FORECLOSURE."

               (iii) IF AN EVENT OF DEFAULT OCCURS, AND THE AGENT ENFORCES ANY
REAL PROPERTY LIEN BY MEANS OF A NON-JUDICIAL FORECLOSURE, TRUSTEE'S SALE OR
POWER OF SALE FORECLOSURE, SUCH BORROWER'S RIGHT OF SUBROGATION TO PROCEED
AGAINST THE OTHER BORROWER WOULD BE EXTINGUISHED BY THE OPERATION OF CALIFORNIA
CODE OF CIVIL PROCEDURE ("CCP") SECTION 580 OR SIMILAR LAWS, AND, IN SUCH CASE,
SUCH BORROWER MIGHT HAVE A DEFENSE AGAINST PAYMENT.

               (iv) IF AN EVENT OF DEFAULT OCCURS, AND THE AGENT ENFORCES ANY
REAL PROPERTY LIEN BY MEANS OF JUDICIAL ACTION, SUCH BORROWER'S RIGHT TO PROCEED
AGAINST THE OTHER BORROWER MIGHT BE LIMITED BY THE OPERATION OF CCP SECTION 580
OR SIMILAR LAWS, IN WHICH CASE SUCH BORROWER MIGHT HAVE A COMPLETE OR PARTIAL
DEFENSE AGAINST PAYMENT.

               NEVERTHELESS, SUCH BORROWER EXPRESSLY, KNOWINGLY AND
INTENTIONALLY WAIVES AND RELINQUISHES ANY AND ALL RIGHTS, DEFENSES OR BENEFITS
THE BORROWER MIGHT HAVE UNDER CCP SECTIONS 580(b) OR 580(d) OR SIMILAR LAWS.

               (v)  IN ADDITION, THE BORROWER WAIVES ALL RIGHTS AND DEFENSES
ARISING OUT OF AN ELECTION OF REMEDIES BY THE EXISTING LENDERS, EVEN THOUGH THAT
ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH RESPECT TO SECURITY
FOR A GUARANTEED OBLIGATION, HAS DESTROYED THE GUARANTOR'S RIGHTS OF SUBROGATION
AND REIMBURSEMENT AGAINST THE PRINCIPAL BY THE OPERATION OF CCP SECTION 580, OR
SIMILAR LAWS OR OTHERWISE.

               (vi) SUCH BORROWER ALSO AGREES THAT THIS AGREEMENT WILL REMAIN
FULLY EFFECTIVE, AND SUCH BORROWER WILL BE LIABLE TO THE AGENT AND THE EXISTING
LENDERS FOR ANY OBLIGATIONS EVEN IF THE AGENT SELLS AN INTEREST IN REAL PROPERTY
BY JUDICIAL


                                       68
<PAGE>

FORECLOSURE ACTION AND SUCH BORROWER'S RIGHTS AGAINST THE BORROWERS ARE LIMITED
BY THE OPERATION OF CCP SECTIONS 580b OR 580d OR SIMILAR LAWS.

          (c)  SUCH BORROWER AGREES THAT THE AGENT AND THE EXISTING LENDERS
SHALL BE UNDER NO OBLIGATION TO:  MARSHAL ANY ASSETS IN FAVOR OF SUCH PERSON, TO
PROCEED FIRST AGAINST ANY OTHER PERSON OR ANY PROPERTY OF ANY OTHER PERSON OR
AGAINST ANY COLLATERAL, ENFORCE FIRST ANY OTHER GUARANTY OBLIGATIONS WITH
RESPECT TO, OR SECURITY FOR, THE OBLIGATIONS, PURSUE ANY OTHER REMEDY IN THE
AGENT'S OR ANY EXISTING LENDER'S POWER THAT SUCH BORROWER MAY NOT BE ABLE TO
PURSUE ITSELF AND THAT MAY LIGHTEN SUCH BORROWER'S BURDEN, ANY RIGHT TO WHICH
SUCH BORROWER HEREBY EXPRESSLY WAIVES.

               EACH BORROWER ACKNOWLEDGES THAT THE FOREGOING WAIVERS ARE A
MATERIAL INDUCEMENT TO THE AGENT'S, THE CO-AGENTS' AND EACH EXISTING LENDER'S
ENTERING INTO THIS AGREEMENT AND THAT THE AGENT, THE CO-AGENTS AND EACH EXISTING
LENDER ARE RELYING UPON THE FOREGOING WAIVERS IN THEIR FUTURE DEALINGS WITH SUCH
BORROWER.  EACH BORROWER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THE
FOREGOING WAIVERS WITH ITS LEGAL COUNSEL.

     11.6.     SUBROGATION.  Each Borrower agrees that it shall have no right of
subrogation, contribution or reimbursement against the other Borrower until the
Obligations are paid in full.  Each Borrower agrees upon making any payment
hereunder to be subrogated to the rights of the payee against the other Borrower
with respect to such payment or against any direct or indirect security
therefor, or otherwise to be reimbursed, indemnified or exonerated by or for the
account of the other Borrower in respect thereof.

     11.7.     STAY OF ACCELERATION.  In the event that acceleration of the time
for payment of any amount payable by either Borrower under this Agreement is
stayed upon insolvency, bankruptcy or reorganization of such Borrower, all such
amounts otherwise subject to acceleration under the terms of this Agreement
shall nonetheless be payable by the other Borrower hereunder forthwith on demand
by the Agent made at the request of the Majority Lenders.


                                   ARTICLE XII

                                  MISCELLANEOUS

     12.1.     NOTICES.  All notices, requests and other communications to any
party hereunder shall be in writing (including bank wire, facsimile transmission
or similar writing) and shall be given to such party at its address or facsimile
number set forth on the Schedule for Notices attached hereto or such other
address or facsimile number as such party may hereafter specify for the purpose
by notice to the Agent and the


                                       69
<PAGE>

Borrowers.  Each such notice, request or other communication shall be effective,
(i) if given by facsimile transmission, when transmitted to the facsimile number
specified in this Section and confirmation of receipt is received, (ii) if given
by mail, seventy-two (72) hours after such communication is deposited in the
mails with first class postage prepaid, addressed as aforesaid or (iii) 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.

     12.2.     ENTIRE AGREEMENT.  The execution and delivery of this Agreement
and the other Loan Documents supersede all the negotiations or stipulations
concerning matters thereof which preceded or accompanied the execution and
delivery hereof and thereof.  This Agreement, and the other Loan Documents are
intended, by the parties hereto and thereto, to be a complete and exclusive
statement of the terms and conditions hereof and thereof.

     12.3.     NO WAIVERS.  No failure or delay by the Agent or any Lender in
exercising any right, power or privilege hereunder or under the other
Restructuring Documents 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
herein provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

     12.4.     EXPENSES; INDEMNIFICATION.

          (a)  The Borrowers shall pay (i) all reasonable out-of-pocket expenses
of the Agent and the Steering Committee Lenders as a group, as such group is
constituted on the Closing Date (as set forth in the attached SCHEDULE 12.4) and
as such group may be reconstituted from time to time including reasonable fees
and disbursements of the Professionals retained by the Steering Committee
Lenders as a whole, in connection with the preparation and administration of
this Agreement, any waiver or consent hereunder or any amendment hereof or any
Default or alleged Default hereunder, (ii) if an Event of Default occurs, all
reasonable out-of-pocket expenses incurred by the Agent and each Steering
Committee Lender, or their Professionals, including the reasonable fees and
disbursements of counsel (including allocated costs of internal counsel), in
connection with such Event of Default and collection, bankruptcy, insolvency and
other enforcement proceedings resulting therefrom, and (iii) all reasonable out-
of-pocket legal fees and expenses of each Existing Lender accruing from and
after the Termination Date in connection with payment of the Obligations.

          (b)  The Borrowers agree to indemnify the Agent and each Existing
Lender, their respective Affiliates and the respective directors, officers,
agents and employees of the foregoing (each an "Indemnitee") and hold each
Indemnitee


                                       70
<PAGE>

harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including the reasonable fees and disbursements of counsel
(including allocated costs of internal counsel), which may be incurred by such
Indemnitee in connection with any investigative, administrative or judicial
proceeding (whether or not such Indemnitee shall be designated a party thereto)
brought or threatened (i) relating to or arising out of this Agreement or any
actual or proposed use of proceeds of Existing Loans hereunder or (ii) directly
or indirectly resulting from, arising out of, or based upon (x) the presence,
use, generation, manufacture, installation, release, discharge, storage or
disposal, at any time, of any Hazardous Materials on, under, in or about, or the
transportation of any such materials to or from, any Real Property or real
property owned, leased or operated by Borrower or any Affiliate of Borrower
(collectively, the "Subject Property") or (y) the violation or alleged violation
by Borrower or any Affiliate of Borrower of any law, statute, ordinance, order,
rule, regulation, permit, judgment or license relating to the use, generation,
manufacture, installation, release, discharge, storage or disposal of Hazardous
Materials to or from the Subject Property; PROVIDED, that no Indemnitee shall
have the right to be indemnified hereunder (A) for such Indemnitee's own gross
negligence or willful misconduct or (B) in the case of any Existing Lender, for
its failure to perform the duties expressly required to be performed by it by
the terms of this Agreement, in each case as determined by a court of competent
jurisdiction.

     12.5.     SET-OFF; SHARING UPON SET-OFF REDUCTIONS IN LIABILITY AND
CONVERSION EVENTS.

          (a)  In addition to any rights and remedies of the Existing Lenders
provided by law, the Existing Lenders each shall have a security interest in any
and all deposits of the Borrowers (general or special, time or demand,
provisional or final) at any time held by any Existing Lender which security
interest shall secure the Obligations.  Upon the occurrence and during the
continuance of an Event of Default, provided that it has first received the
written consent of the Agent, without prior notice to the Borrowers (any such
notice being specifically waived by the Borrowers to the fullest extent
permitted by applicable law) each Existing Lender may set off and apply against
any Obligations, whether matured or unmatured, of the Borrowers to the Existing
Lenders, any amount owing from the Existing Lenders to the Borrowers.  No
Existing Lender shall exercise any right of set-off it may have against any
Borrower or Guarantor in connection with the Obligations without the prior
written consent of the Agent.  Each Existing Lender promptly shall notify the
Borrowers and the Agent after any such setoff and application made by any such
Existing Lender; PROVIDED, HOWEVER, that failure to give such notice shall not
affect the validity of such setoff and application.  Provided that an Event of
Default described in either SECTION 9.1(f) or SECTION 9.1(g) has not occurred,
Bank of America National Trust and Savings Association expressly agrees


                                       71
<PAGE>

that it will not exercise set-off rights with respect to cash in the Cash
Management System for application against any Indebtedness, liabilities or other
obligations of any of the Borrowers, Guarantors or any Consolidated Subsidiaries
under any agreements, other than the Existing Agreements and the other
Restructuring Documents.  Any such set-off rights will be subject to the
Intercreditor Agreement.

          (b)  Each Existing Lender (other than Citibank, N.A. and Morgan
Guaranty Trust Company of New York with respect to Letter of Credit Fees under
the reimbursement agreements under which the NYCTA/PB Letters of Credit were
issued) agrees that:

               (i)  to the extent that it shall receive or shall have received
or collect, in respect of any of the Obligations, any payment or distribution of
any cash or other property of any Borrower or any Guarantor at any time,
including by payment or distribution from any Borrower or any Guarantor, by
exercise of any right of set-off or counterclaim by liquidation of Collateral,
by reason of Conversion Events or Reductions in Liability, as a distribution in
a bankruptcy, insolvency or similar proceeding or otherwise, and any such
payment or distribution results in such Existing Lender's receiving or having
received more than it would otherwise be entitled to receive under this
Agreement (in the case of a Reduction in Liability, calculated, other than for
purposes of accruing interest and fees, as if such Reduction in Liability had
occurred before July 1, 1995), such Existing Lender shall promptly deliver the
same to the Agent in cash or the form received (except for the endorsement or
the assignment of or by such Existing Lender where necessary), and subject to
SECTION 12.5(d), the Agent shall promptly distribute the same to all Existing
Lenders in the same manner as if it were a payment to be distributed pursuant to
SECTION 2.11 (and such payment shall be applied as provided in SECTION 2.10),
including making a distribution to the Contingent Indebtedness Account on
account of the Existing Contingent Indebtedness and the Metra Guaranty as
provided in SECTION 2.11(b), and until so delivered or disbursed pursuant to
SECTION 2.11(f), the same shall be held in trust by such Existing Lender as
property of all Existing Lenders; and

               (ii) to the extent that any payment or other transfer made under
this Agreement on account of the principal portion of any Obligations shall be
recovered (a "Returned Payment") from any Existing Lender pursuant to any
preference, fraudulent transfer of similar provision under any bankruptcy,
insolvency or similar law or otherwise, each other Existing Lender shall
purchase from such Existing Lender a participation in its Pro Rata Share of such
Returned Payment; PROVIDED, that nothing in this Section shall impair the right
of any Existing Lender (other than Bank of America National Trust and Savings
Association with respect to the Cash Management System) to exercise any right of
set-off or counterclaim it may have and to apply the amount subject to such
exercise to the payment of


                                       72
<PAGE>

Indebtedness of a Borrower other than its Existing Indebtedness; AND PROVIDED
FURTHER, that no Existing Lender shall be required to purchase any such
participation pursuant to this SECTION 12.5(b) because of a Reduction in
Liability, except to the extent such Existing Lender has, as determined pursuant
to SECTION 2.12, received amounts under this Agreement in excess of the amount
that it is otherwise entitled to receive under this Agreement (calculated, other
than for purposes of accruing interest and fees, as if such Reduction in
Liability had occurred before July 1, 1995).

          (c)  To the extent that any Existing Lender is required by the
provisions of SECTION 12.5(b) to purchase a participation in the Existing Loans
of one or more other Existing Lenders, such purchase shall be effected by (i)
the payment to the Agent by the Existing Lender making such purchase of the
amount required to be paid, and (ii) the Agent's distribution of the amount or
amounts required to be paid to the respective Existing Lender or Existing
Lenders from whom such purchase is required to be made.  To the extent that any
Existing Lender is required by the provisions of SECTION 12.5(b) to purchase a
participation in the Existing Contingent Indebtedness or the Contingent
Obligations with respect to the Metra Guaranty of one or more other Existing
Lenders, such purchase shall be effected by (x) the payment to the Agent by the
Existing Lender making such purchase of the amount required to be paid, and
(y) the Agent's distribution into the Contingent Indebtedness Account pursuant
to SECTION 2.11(b) of the amount or amounts required to be paid for the account
of the respective Existing Lender or Existing Lenders from whom such purchase is
required to be made; PROVIDED that funds held in the Contingent Indebtedness
Account may be applied by the Agent to effect the purchase of a participation by
Existing Lenders on whose behalf such funds are held.  Each Borrower agrees, to
the fullest extent it may effectively do so under applicable law, that any
holder of a participation in Existing Indebtedness, whether or not acquired
pursuant to the foregoing arrangements, may exercise any rights of set-off or
counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of such Borrower in the
amount of such participation.

          (d)  The Existing Lenders shall deliver to the Agent any distributions
of property other than cash (distributions of cash shall be treated as provided
in SECTION 12.5(b)) received from the Borrowers, the Guarantors or their
successors in interest on account of the Obligations in connection with any
recapitalization of the Borrowers (other than a recapitalization in connection
with any bankruptcy or insolvency proceeding) that the Existing Lenders receive
on account of the Obligations.  The Agent shall deposit such property with the
Collateral Agent and upon the liquidation of such property, such property shall
be distributed to the Existing Lenders as provided in SECTION 2.11 and applied
to the Obligations as provided in SECTION 2.10.


                                       73
<PAGE>

          (e)  Each Existing Lender agrees to the provisions of this SECTION
12.5 on behalf of any assignee under its Existing Agreement.

     12.6.     AMENDMENTS AND WAIVERS.  Any provision of this Agreement or the
other Loan Documents other than the Warrants may be amended or waived if, but
only if, such amendment or waiver is in writing and is signed by the Borrowers,
the Agent and the Majority Lenders; PROVIDED, that (i) the consent of All
Existing Lenders shall be required to amend, modify or waive any provision
relating to (a) a change in the amount or the time of payment of any amount
owing on any of the Existing Indebtedness, (b) a change in the rate of interest
or fees to be paid by the Borrowers with respect to any of the Existing
Indebtedness, (c) a change in the definitions of "All Lenders," "Conversion
Event," "Equilibrium," "Exposure," "Liquidated Contingent Liability," "Majority
Lenders," "Metra Exposure Percentage," "Metra Final Accounting Date," "Metra
Lenders," "Non-Metra Exposure Percentage," "Non-Metra Lenders," "Pro Rata
Share," "Pro Rata Share of Deferred Interest," "Reductions in Liability," or the
definitions referred to therein, (d) any change that subjects any Existing
Lender to any additional obligation, (e) this SECTION 12.6, SECTION 2.11,
SECTION 12.5(b), SECTION 12.20, or SECTION 12.21, (f) the release of any
Guarantor or any Borrower, (g) any change in the lien priorities created by, or
other material terms of, the Intercreditor Agreement or the Distribution
Agreement, and
(h) release of any Collateral that is not identified in the Asset Disposition
Program (for which the consent of the Majority Lenders shall be required) or
otherwise permitted to be released in connection with the Loan Documents; (ii)
any change in the duties of or indemnities in this Agreement in favor of any
Existing Lender or in an Existing Lender's Pro Rata Share or Pro Rata Share of
Deferred Interest shall require the consent of such Existing Lender; and
(iii) any change in the duties of or indemnities in favor of the Agent shall
require the consent of the Agent.  Notwithstanding anything to the contrary
herein, the Agent and the Majority Lenders may modify, amend, restate,
supplement or waive any provision of ARTICLE X, other than SECTION 10.13,
without the consent of the Borrowers; AND PROVIDED further that amendments or
waivers of this Agreement are subject to the Intercreditor Agreement.

     12.7.     EFFECT OF WAIVERS; MODIFICATION OF DOCUMENTS.  The Agent's, the
Collateral Agent's or the Existing Lenders' failure, at any time or times, to
require strict performance by the Borrowers or any other Person of any provision
of this Agreement or any of the other Loan Documents shall not waive, affect or
diminish any right of the Agent, the Collateral Agent or the Existing Lenders
thereafter to demand strict compliance and performance therewith.  Any
suspension or waiver by the Agent, the Collateral Agent or the Existing Lenders
of a Default or Event of Default under this Agreement or any of the other Loan
Documents, shall not suspend, waive or affect any other Default


                                       74
<PAGE>

or Event of Default under this Agreement or any of the other Loan Documents,
whether the same is prior or subsequent thereto and whether of the same or of a
different type.  Subject to SECTION 12.20 and the Intercreditor Agreement, no
waiver of any provision of this Agreement or any other Loan Documents, nor
consent to any departure by the Borrowers, or any other person or entity
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Agent or the Majority Lenders or All Existing Lenders, as the
case may be, necessary to effectuate such waiver or consent and then such waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given.

     12.8.     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 neither Borrower may assign or otherwise transfer any of
its rights under this Agreement without the prior written consent of All
Existing Lenders.

          (b)  Any Existing Lender may at any time grant a participating
interest in its Existing Indebtedness to any Person (a "Participant").  In the
event of any such grant by an Existing Lender of a participating interest to a
Participant, whether or not upon notice to the Borrowers and the Agent, such
Existing Lender shall remain responsible for the performance of its obligations
hereunder, and the Borrowers and the Agent shall continue to deal solely and
directly with such Existing Lender in connection with such Existing Lender's
rights and obligations under this Agreement.  Any agreement pursuant to which
any Existing Lender may grant such a participating interest shall provide that
such Existing Lender shall retain the sole right and responsibility to enforce
the Obligations of the Borrowers hereunder, including the right to approve any
amendment, modification or waiver of any provision of this Agreement.  The
Borrowers agree that each Participant shall, to the extent provided in its
participation agreement, be entitled to the benefits of ARTICLE II with respect
to its participating interest.  An assignment or other transfer which is not
permitted by subsection (c) 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 Existing Lender may at any time assign to any Person (each an
"Assignee") all of its rights and obligations under this Agreement or its
Existing Agreements, as modified hereby or any part thereof, and such Assignee
shall assume such rights and obligations, pursuant to an assignment and
assumption agreement executed by such Assignee and such transferor Existing
Lender in substantially the form attached hereto as EXHIBIT B.  Upon execution
and delivery of such instrument and payment by such Assignee to such transferor
Existing Lender of an amount


                                       75
<PAGE>

equal to the purchase price agreed to between such transferor Existing Lender
and such Assignee, such Assignee shall be deemed to be an Existing Lender under
this Agreement and shall have all of the rights and obligations of an Existing
Lender with a proportionate share of the transferor Existing Lender's Pro Rata
Share and Pro Rata Share of Deferred Interest, if any, as set forth in such
instrument of assumption, and the transferor Existing Lender shall be released
from its obligations hereunder to a corresponding extent, and no further consent
or action by any party shall be required.

          (d)  Notwithstanding anything to the contrary in the foregoing, the
assignment and transfer of rights and obligations of any Metra Lenders under the
Metra Guaranty shall also be subject to any conditions or limitations set forth
in the Metra Credit Agreement.

          (e)  Each Existing Lender agrees that it shall not assign all or any
portion of its interests under its Existing Agreements or the Metra Guaranty
unless the assignee has agreed to be bound by SECTION 12.5.

     12.9.     HEADINGS AND CAPTIONS.  The headings and captions used in this
Agreement and the other Restructuring Documents are solely for the purpose of
reference and are not to be considered as construing or interpreting the
provisions hereof or thereof.

     12.10.    INTERPRETATION.  Neither this Agreement or the other
Restructuring Documents, nor any uncertainty or ambiguity herein or therein
shall be construed or resolved against the Agent, the Existing Lenders or the
Borrowers, whether under any rule of construction or otherwise.  This Agreement
and the other Restructuring Documents have been reviewed by all the parties
hereto and thereto and shall be construed and interpreted according to the
ordinary meaning of the words used as to fairly accomplish the purposes and
intentions of all such parties.

     12.11.    INCONSISTENCIES WITH OTHER DOCUMENTS.  In the event there is a
conflict or inconsistency between this Agreement and the other Loan Documents,
FIRST the terms of the Intercreditor Agreement shall control and SECOND the
terms of this Agreement shall control; PROVIDED, HOWEVER, that any provision of
the Security Documents which imposes additional burdens on the Borrowers or
further restricts the rights of the Borrowers or gives the Existing Lenders
additional rights shall not be deemed to be in conflict or inconsistent with
this Agreement and shall be given full force and effect.

     12.12.    SEVERABILITY.  If any portion of this Agreement, and the other
Loan Documents shall be judged by a court of competent jurisdiction to be
unenforceable, the remaining portions shall be valid and enforceable to the
extent that the remaining terms thereof provide for the grant of collateral
security for the Obligations under this Agreement, and the payment of principal


                                       76
<PAGE>

PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS, ON BEHALF OF THEMSELVES AND THEIR
PROPERTY, IN THE MANNER SPECIFIED IN SECTION 12.1 (PROVIDED TELECOPY NOTICES MAY
NOT BE USED FOR THIS PURPOSE).  NOTHING IN THIS SECTION 12.14 SHALL AFFECT THE
RIGHT OF THE AGENT OR ANY EXISTING LENDER TO SERVE LEGAL PROCESS IN ANY OTHER
MANNER PERMITTED BY LAW OR AFFECT THE RIGHT OF THE AGENT OR ANY EXISTING LENDER
TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWERS OR THEIR PROPERTIES IN
THE COURTS OF ANY OTHER JURISDICTIONS.

     12.15.    WAIVER OF JURY TRIAL.  THE AGENT, EACH EXISTING LENDER AND THE
BORROWERS EACH HEREBY IRREVOCABLY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT
TO ANY ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN
CONNECTION WITH THIS AGREEMENT, THE OTHER LOAN DOCUMENTS OR THE EXISTING
AGREEMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE
PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

                                       77
<PAGE>

     12.18.    RELATIONSHIP OF THE PARTIES.  Neither the Agent nor the Existing
Lenders shall be deemed partners or joint venturers with the Borrowers or any
Affiliate thereof in making this Agreement or by any action taken hereunder.

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

     12.20.    VOTING BY THE METRA LENDERS.  Any vote (a) at any time at which
the Non-Metra Exposure Percentage exceeds the Metra Exposure Percentage, with
respect to the following:

          (i)  the reduction in the amount or a postponement of the time of
payment of any amount owing on any of the Obligations,

recapitalization of any Borrower or any Guarantor, including property received
in connection with the events specified in subclauses (a)(v) and (a)(vi) of this
SECTION 12.20;

shall require the consent of All Existing Lenders, PROVIDED that if one Metra
Lender does not consent and all other Existing Lenders do consent, such vote

consent, the requisite vote will have been obtained and if two Metra Lenders do
not consent, the requisite vote will not have been obtained); PROVIDED FURTHER
that any such action shall equally affect an amount of each Existing Lender's

entitled to receive any payment or distribution at any time in respect of the
Metra Guaranty from the Borrowers, any Guarantor or proceeds of Collateral in
connection with this Agreement or the other Loan Documents prior to the first
time on or after the Metra Final Accounting Date that the Metra Exposure
Percentage equals or exceeds the Non-Metra Exposure Percentage calculated, for
the purpose of this SECTION 12.21 as if the Metra Holdback is zero (0).  If any
such payments are received they shall be paid to the Agent pursuant to SECTION
12.5.

     12.22.    AFFIRMATION OF PAYMENTS OF OBLIGATIONS.  Nothing contained in
SECTIONS 2.10, 2.11 or 12.5, or any other provision of this Agreement, is
intended to or shall impair the obligations of the Borrowers and the Guarantors,
which are absolute and unconditional, to pay all amounts owing in respect of the
Obligations as and when the same shall become due and payable in accordance with
their terms.

     12.23.    AMENDMENT OF METRA CREDIT AGREEMENT.  The Metra Agent and the
Metra Lenders hereby agree that they shall not enter into any amendment or
modification of the Metra Credit Agreement that increases the maximum amount
payable under the Metra Credit Agreement without the consent of All Existing
Lenders.

     12.24.    ACKNOWLEDGEMENT AND ACCEPTANCE OF THE INTERCREDITOR AGREEMENT.
Each of the Existing Lenders and the Metra Agent agree to and acknowledge the
terms of the Intercreditor Agreement and agree to be bound by the terms thereof
as it applies to the Existing Lenders and the Agent.

     12.25.    APPROVAL OF FIRST AMENDMENT TO COLLATERAL AGENT AGREEMENT.  The
Agent and the Existing Lenders hereby agree to the terms of the First Amendment
to Collateral Agent Agreement and Mortagage Trust in the form of EXHIBIT D,
agree to be bound by such amendment as if they had executed it, and appoint
Mellon Bank, N.A. as Collateral Agent and Mortgage Trustee thereunder, as set
forth therein.

            FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT


          THIS FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT (this
"Amendment") dated as of October 10, 1995 is entered into among MORRISON KNUDSEN
CORPORATION, a Delaware corporation ("MKD"), and MORRISON KNUDSEN CORPORATION,
an Ohio corporation ("MKO") (MKD and MKO each a "Borrower," and collectively,

to the Credit Agreement (as defined below) and whose signatures appear on the
signature pages hereto (each, together with its successors and assigns, a
"Lender," and collectively, the "Lenders"), Mellon Bank, N.A., as administrative
agent for the Lenders (in such capacity, the "Administrative Agent"), and Mellon

the following facts:

                                    RECITALS

     A.   Pursuant to the Amended and Restated Credit Agreement dated as of July
31, 1995 by and among the Borrowers, the Lenders, the Administrative Agent and
the Co-Agents (the "Credit Agreement"), the Lenders agreed to make certain
financial accommodations to or for the benefit of the Borrowers upon the terms
and conditions contained therein.  Unless otherwise defined in this Amendment,
(i) capitalized terms used herein shall have the meanings attributed to them in
the Credit Agreement as amended hereby, and (ii) references to sections and
subsections shall refer to sections or subsections of the Credit Agreement.

     B.   In connection with the second phase of the restructuring of the

requested that the Credit Agreement be amended.

     D.   The Lenders are willing to amend the Credit Agreement upon the terms
and conditions set forth in this Amendment, but only upon the condition, among
others, that the Borrowers, the Administrative Agent, the Co-Agents and the
Lenders shall have executed and delivered this Amendment to the Administrative
Agent.

          NOW, THEREFORE, in consideration of the continued performance by the
Borrowers of their promises and obligations under the Credit Agreement and the
other Loan Documents, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

                                A G R E E M E N T

     1.   AMENDMENT TO CREDIT AGREEMENT.

          1.1  Section 1.1 of the Credit Agreement is hereby amended as follows:

              (a)   The definition of Cash Equivalent is hereby amended by
deleting the phrase "Standard & Poor's Corporation" and substituting the phrase

                             REIMBURSEMENT AGREEMENT

          THIS REIMBURSEMENT AGREEMENT ("Agreement") dated as of October 10,
1995, by each of Morrison Knudsen Corporation, a Delaware corporation ("MKD"),
Morrison Knudsen Corporation, an Ohio Corporation ("MKO"), and each of the
affiliates of MKD listed on the signature pages hereof (collectively, the
"Obligors," and each, an "Obligor"), to and for the benefit of Fidelity and
Deposit Company of Maryland (the "Bonding Company").

                                    RECITALS

          A.   Reference is made to (1) the Guaranty Agreement dated as of
October 10, 1995 by the Bonding Company in favor of Credit Suisse (the "Guaranty
Agreement") and (2) the Override Agreement dated as of July 31, 1995 among MKD,
MKO, the Banks and Other Financial Institutions Named Therein and Mellon Bank,
N.A., as Agent (as amended from time to time, the "Override Agreement").
Capitalized terms used but not defined herein have the meanings assigned to such
terms in the Guaranty Agreement.

          B.   In order to induce the Bonding Company to participate in a global
restructuring (the "Global Restructuring") of certain obligations of MKO and
MKD, the Bonding Company has required that the Obligors execute and deliver to
the Bonding Company this Agreement.

<PAGE>

          C.   MKO has operated a public transportation manufacturing business
(the "Business") providing engineering services and manufacturing and
refurbishing light rail cars for various municipalities and other governmental
entities (collectively, the "Transit Division Customers").

          D.   The Transit Division Customers, the Obligors, the Bonding
Company, and other parties have agreed to a global restructuring of certain
obligations of the Obligors (the "Global Restructuring"), the principal terms
and conditions of which include, among other things, that MKO would transfer and
assign to American Passenger Rail Car Company, L.L.C. (the "Borrower") assets
used to conduct the Business in accordance with the terms of an Asset Purchase
Agreement dated as of October 10, 1995 (the "Asset Purchase Agreement").  In
connection with the Guaranty Agreement, the Bonding Company and the Borrower
have entered into an Indemnification and Reimbursement Agreement dated as of
October 10, 1995 (the "Indemnification and Reimbursement Agreement").

          E.   The Sureties are concurrently entering into a Release of even
date in reliance upon each of the following, and would not execute such Release
in the absence of any of the following:  (i) the validity and enforceability of
this Agreement, the Distribution Agreement (as defined in the Override Agreement
as in effect on the date hereof) and the documents securing the obligations of
the Obligors under this Agreement, (ii) the validity and enforceability of each
of the transactions contemplated by


                                       -2-
<PAGE>

the Asset Purchase Agreement, (iii) neither the Borrower nor the Sureties will
be required to make any post closing payments as a consequence of any bankruptcy
proceeding or otherwise, in order to retain the benefits of the assets
transferred in the Asset Purchase Agreement, including the contracts with the
Transit Division Customers.

          F.   Accordingly, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, the Obligors hereby agree as
follows:

          SECTION 1.     Each of the Obligors absolutely and unconditionally
agrees, jointly and severally, to indemnify and pay the Bonding Company (a) for
any losses incurred by the Bonding Company under, pursuant to or in connection
with the Guaranty Agreement or the Indemnification and Reimbursement Agreement
and (b) for any losses incurred by the Bonding Company in connection with (i)
any loan it makes to the Borrower, (ii) any extensions of credit made pursuant
to Section 2.4 of the Intercreditor and Subordination Agreement dated as of
October 10, 1995 among the Bonding Company, Bank of America National Trust and
Savings Association, as agent for itself and certain other banks and financial
institutions, or (iii) matters referred to in Section 2 of the Agreement of
Indemnity dated as of October 10, 1995 between the Borrower and the Bonding
Company (in calculating the losses of the Bonding Company under this paragraph,
any amounts paid by the Bonding Company to any third party shall bear interest
at the interest rate then being charged under the Override Agreement (which may


                                       -3-
<PAGE>

be the Prime Rate or the Default Rate, each as defined in the Override
Agreement) (the "Obligations"); PROVIDED, HOWEVER, that the maximum amount of
the Obligations hereunder shall not, except for interest referred to in the
following sentence, exceed $31,249,377.00.  After the amount of the
"Obligations" hereunder has become fixed at an amount not to exceed
$31,249,377.00, such amount shall thereafter bear interest until paid at the
interest rate then being charged under the Override Agreement (which may be the
Prime Rate or the Default Rate, each as defined in the Override Agreement).  The
losses referred to in this Section 1 refer only to losses incurred in connection
with the Borrower's performance of the Transit Division Contracts (as defined in
the Asset Purchase Agreement) and not in connection with the Borrower's
performance of other contracts or projects undertaken by the Borrower.  In
calculating the amount of such losses, any recovery received by the Bonding
Company from any disposition of the Borrower shall not reduce such loss.  The
losses referred to above will be fixed on the day (the "Loss Determination
Date") that is ninety (90) days after the date the last railcar manufactured
pursuant to the Transit Division Contracts (as defined in the Asset Purchase
Agreement) is accepted by a Transit Division Customer.  The Obligors shall make
payments with respect to the Obligations in accordance with the Distribution
Agreement (as defined in the Override Agreement as in effect on the date
hereof).

          SECTION 2.     Each of the Obligors waives presentment to, demand of
payment from and protest to any other corporation, partnership, company, person,
firm or other entity (any of which a "Person") obligated with respect to any of
the Obligations,


                                       -4-
<PAGE>

and also waives notice of acceptance and notice of protest for nonpayment.  The
obligations of each Obligor hereunder shall not be affected by: (a) the failure
of the Bonding Company to assert any claim or demand or to enforce any right or
remedy against any Obligor; or (b) any rescission, waiver, amendment or
modification of, or any release from any of the terms or provisions of, any
guarantee or any other agreement, including with respect to any other Obligor
under this Agreement.

          SECTION 3.  Each of the Obligors waives any right to require that any
resort be had by the Bonding Company to any other Person responsible for the
Obligations or any security held for payment of the Obligations.

          SECTION 4.  The obligations of each Obligor hereunder shall be
absolute and unconditional and shall not be subject to any reduction,
limitation, impairment or termination for any reason, including, without
limitation, any claim of waiver, release, surrender, alteration or compromise,
and shall not be subject to any setoff, counterclaim, deduction, diminution,
abatement, suspension, reduction, recoupment, termination or defense (other than
full and strict indefeasible satisfaction of the Obligations) whatsoever.
Without limiting the generality of the foregoing, the obligations of each
Obligor hereunder shall not be released, discharged, impaired or otherwise
affected by any circumstance or condition whatsoever (whether or not the Obligor
has knowledge thereof) which may or might in any manner or to any extent vary
the risk of any Obligor or otherwise operate as a discharge of any Obligor as a
matter of law or equity (other than the indefeasible


                                       -5-
<PAGE>

payment in full of all of the Obligations), including, without limitation:

               (a)  any amendment, modification, addition, deletion or
supplement to or other change to any of the terms of the Guaranty Agreement, the
Credit Agreement or any other instrument or agreement applicable to any of the
parties hereto or thereto, or any assignment or transfer of any thereof, or any
furnishing, acceptance, surrender, substitution, modification or release of any
security for any of the Obligations, or the failure of any security or the
failure of any person to perfect any interest in any collateral;

               (b)  any failure, forbearance, omission or delay on the part of
any Obligor or the Bonding Company to conform or comply with any term of any
instrument or agreement, or any failure to give notice to any Person of the
occurrence of an Event of Default under the Guaranty Agreement or the Credit
Agreement;

               (c)  any waiver of the payment, performance or observance of any
of the obligations, conditions, covenants or agreements contained in the
Guaranty Agreement or the Credit Agreement, or any other waiver, consent,
extension, renewal, indulgence, compromise, release, settlement, refunding or
other action or inaction under or in respect of the Obligations, or under or in
respect of any obligation or liability of the Borrower or any Obligor or the
Bonding Company or any exercise or non-exercise of any right, remedy, power or
privilege under or in respect of any of the foregoing;


                                       -6-
<PAGE>

               (d)  any extension of the time for payment of the principal of or
interest, or of the time for performance, of any obligations, covenants or
agreements under or arising out of the Guaranty Agreement or the Credit
Agreement, or the extension or the renewal thereof;

               (e)  any failure, omission or delay on the part of the Bonding
Company to enforce, assert or exercise any right, power or remedy conferred on
it in any agreement relating to the Obligations, or any other failure, omission,
delay, action or inaction on the part of the Bonding Company;

               (f)  to the extent permitted by applicable law, any voluntary or
involuntary bankruptcy, insolvency, reorganization, moratorium, arrangement,
adjustment, readjustment, composition, assignment for the benefit of creditors,
receivership, conservatorship, custodianship, liquidation, marshaling of assets
and liabilities or similar proceedings with respect to any Obligor or any other
Person or any of their respective properties or creditors, or any action taken
by any trustee or receiver or by any court in any such proceeding (including,
without limitation, any automatic stay incident to any such proceeding); or

               (g)  any other occurrence, circumstance, happening or event
whatsoever, whether similar or dissimilar to the foregoing, whether foreseen or
unforeseen, and any other circumstance which might otherwise constitute a legal
or



                                       -7-
<PAGE>

equitable defense, release or discharge (including the release or discharge of
the liabilities of a obligor or surety or which might otherwise limit recourse
against any Obligor, whether or not the Obligor shall have notice or knowledge
of the foregoing).

          SECTION 5.  Each of the Obligors agrees that its obligations hereunder
shall continue to be effective or be reinstated, as the case may be, if at any
time payment, or any part thereof, of any Obligation is rescinded, invalidated,
declared to be fraudulent or preferential, or must otherwise be returned,
refunded, repaid or restored by the Bonding Company upon the bankruptcy or
reorganization of any Obligor or otherwise.

          SECTION 6.  None of the Obligors shall have any right by way of
subrogation, contribution or otherwise as a result of the payment of any sums
hereunder.  Each of the Obligors agrees that it will never have, and hereby
waives and disclaims, any claim or right against the Borrower or any other
Person by way of subrogation, contribution or otherwise in respect of any
payment that such Obligor may be required to make hereunder.

          SECTION 7.  Each Obligor represents, warrants and covenants that this
Agreement has been duly authorized by each Obligor and constitutes the legal,
valid and binding obligation of each Obligor, enforceable against each Obligor
in accordance with its terms.


                                       -8-
<PAGE>

          SECTION 8.  This Agreement shall be binding upon each Obligor and its
successors, and shall inure to the benefit of the Bonding Company and its
successors and assigns.  None of the Obligors may assign or transfer any of its
rights or obligations under this Agreement, without the prior written consent of
the Bonding Company.

          SECTION 9.  No failure on the part of the Bonding Company to exercise,
and no delay in exercising, any right, power or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right,
power or remedy by the Bonding Company preclude any other or further exercise
thereof or the exercise of any other right, power or remedy.  All remedies
hereunder are cumulative and are not exclusive of any other remedies provided by
law.  The Bonding Company shall not be deemed to have waived any rights
hereunder or under any other agreement or instrument unless such waiver shall be
in writing and signed by the Bonding Company.

          SECTION 10.  This Agreement shall be construed in accordance with and
governed by the laws of the State of New York, without regard to its conflict of
laws doctrine.

          SECTION 11.    All notices, requests and other communications to any
party hereunder shall be in writing (including telex, facsimile transmission or
similar writing) and shall be given to such party at its address, facsimile
number or telex number set forth below or such other address, facsimile number
or telex number as such party may

                                    GUARANTY


          This GUARANTY is entered into as of October 10, 1995, among MORRISON
KNUDSEN CORPORATION, a Delaware corporation ("MKD") and MORRISON KNUDSEN
CORPORATION, an Ohio corporation ("MKO" and with MKD, collectively, the

agent (in such capacity, the "AGENT") for itself and the banks (collectively,
the "BANKS" and individually a "BANK") party to the Revolving Credit Agreement
referred to below.

                                    RECITALS

          A.   Prior to the date hereof MKO, the Agent and certain of the Banks
entered into that certain Standby Letter of Credit Reimbursement Agreement dated
as of August 4, 1992, as amended by that certain Waiver and Amendment to Credit
Agreement dated as of December 22, 1992, by that certain Waiver and Second

          B.   Pursuant to the Reimbursement Agreement, Bank of America National
Trust and Savings Association, in its capacity as issuing bank, issued a letter
of credit (as amended to the date hereof, the "ORIGINAL LETTER OF CREDIT") for
the benefit of Metra (as defined in the Revolving Credit Agreement referred to
below) and for the account of MKO, which Letter of Credit is in the form of
Exhibit 2.01 to the Reimbursement Agreement.

          D.   MKO, the Agent and certain of the Banks have entered into that
certain Revolving Credit Agreement dated as of July 31, 1995, as amended to date
(as so amended, the "ORIGINAL CREDIT AGREEMENT").

          E.   Pursuant to the Original Credit Agreement, the Banks agreed to
provide financing to MKO to be used by MKO exclusively to fund MKO's performance
of the Contract (as defined in the Revolving Credit Agreement referred to
below).

          F.   Pursuant to that certain Guaranty dated as of July 31, 1995, MKD
guaranteed all obligations of MKO under the Original Credit Agreement.

          G.   Pursuant to a restructuring being entered into concurrently
herewith, (i) the Company has requested that the Issuing Bank (as defined in the
Revolving Credit Agreement referred to below) issue, for the account of American
Passenger Rail Car Company, L.L.C., a Delaware limited liability company (the
"Borrower"), a letter of credit to Metra as beneficiary in substitution for the
Original Letter of Credit, (ii) MKO has agreed to transfer all of its rights,
duties and obligations under the Contract to the Borrower, and the Borrower has
agreed to assume and become liable therefor and (iii) the Borrower has requested
that the Banks provide revolving credit to the Borrower on the terms and
conditions herein set forth in that certain Revolving Credit Agreement dated as
of October 10, 1995 (the "Revolving Credit Agreement").

          H.   In connection with the restructuring, the Issuing Bank has issued
or is issuing concurrently herewith a letter of credit for the benefit of Metra
and for the account of the Borrower, which letter of credit is in the form of
EXHIBIT 2.01 to the Revolving Credit Agreement (as amended, modified or
supplemented from time to time, the "LETTER OF CREDIT").  The Banks have agreed
to participate in such letter of credit on the terms set forth in the Revolving
Credit Agreement, and the Borrower has agreed to reimburse the Banks for any
drawing under the Letter of Credit pursuant to the provisions of the Revolving
Credit Agreement.

          I.   Further, in connection with the restructuring, the Banks have
agreed to make certain amounts available to the Borrower pursuant to the
provisions of the Revolving Credit Agreement and the Borrower has agreed to
repay the Banks for amounts so made


                                       -2-

available pursuant to the terms of the Revolving Credit Agreement.  Upon
occurrence of the Closing Date, as defined in the Revolving Credit Agreement,
among other things, (i) the Reimbursement Agreement and the Original Credit
Agreement shall terminate, except for certain warranties and indemnities
provided therein, (ii) the Original Letter of Credit shall be returned to the
Issuing Bank, (iii) the Revolving Credit Agreement shall become effective and
(iv) the Letter of Credit shall be issued and delivered to Metra.

          J.   Further, in connection with the restructuring and as a material
part of it, MKD and MKO have agreed, at the request of the Banks, to guarantee
all obligations of the Borrower existing from time to time under the terms of
the Revolving Credit Agreement and any other documents entered into by the
Borrower in connection herewith.

          K.   In order to induce the Banks to commit to extend credit to the
Borrower as provided in the Revolving Credit Agreement, and for other valuable
consideration, the Guarantors issue this Guaranty of the Borrower's indebtedness
and obligations under the Revolving Credit Agreement.

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, and to induce Banks to make the Loans pursuant to
the terms of the Credit Agreement, it is agreed as follows:

2.   THE GUARANTY

     2.1  GUARANTY OF THE OBLIGATIONS.  In consideration of the Loans and all
other financial accommodations to or for the benefit of the Borrower, and for
other valuable consideration, receipt of which Guarantors hereby acknowledge and
for the benefit of Agent and each Bank, and their successors, endorsees,
transferees, and assigns, Guarantors hereby jointly and severally (i)
unconditionally guarantee to Agent, the prompt payment (whether at stated
maturity, by acceleration or otherwise) and performance of the Obligations and
(ii) agree to pay all indebtedness, liabilities and obligations of the
Guarantors to Agent or the Banks, whether now existing or hereafter arising,
under the Guaranty or any other Related Document.

     2.2  ABSOLUTE GUARANTY.  The Guaranty Liabilities are the immediate,
direct, primary, and absolute obligations of Guarantors, shall not be subject to
any condition precedent, and are independent of and not co-extensive with the
Obligations.  The Guaranty Liabilities shall remain in full force and effect
without regard to, and shall not be impaired or affected by, or be deemed to be
satisfied by, nor shall Guarantors or the Collateral be exonerated, discharged,
or released by, any of the following events:


                                       -5-
<PAGE>

          (a)  Agent's or any Bank's exercise or enforcement of, or failure or

the Obligations or the Guaranty Liabilities;

          (b)  insolvency, bankruptcy, reorganization, arrangement, adjustment,
composition, assignment for the benefit of creditors, appointment of a receiver

          (c)  any limitation, discharge, cessation, or partial satisfaction of

Agent or any Bank, or any invalidity, voidability, unenforceability, or
irregularity, or future change to or amendment of, in whole or in part, the
Revolving Credit Agreement, this Guaranty, any other Related  Document, or any
other document evidencing any Obligations;

          (d)  any merger, acquisition, consolidation or change in structure of
Borrower or Guarantor or any guarantor of the Obligations; or any sale, lease,
transfer, or other disposition of any or all of the assets or shares of Borrower
or Guarantors or any other guarantor of the Obligations;

          (e)  any assignment or other transfer, in whole or in part, of Agent's
or any Bank's interest in and rights


                                       -6-
<PAGE>

under the Revolving Credit Agreement or any other Related Document, including
this Guaranty, or of Agent's or any Bank's interest in the Obligations, the
Guaranty Liabilities, or the Collateral;

          (f)  any claim, defense, counterclaim, or set-off, other than (i) any
defense of prior performance or (ii) any defense based on any applicable
provision of the UCC requiring that the Collateral be disposed of in a
commercially reasonable manner, which Borrower, Guarantors, or any other
guarantor of the Obligations may have or assert, including any defense of
incapacity, disability, or lack of corporate or other authority to execute any
documents relating to the Obligations, the Guaranty Liabilities, the Collateral,
or any other guaranty of the Obligations;

          (g)  any cancellation, renunciation, or surrender of any pledge,

Liabilities;

          (h)  Agent's or any Bank's vote, claim, distribution, election,
acceptance, action, or inaction in any bankruptcy or reorganization case related
to the Collateral, the Obligations, or the Guaranty Liabilities;

          (i)  Obligations arising under the Revolving Credit Agreement as a
result of the Bonding Company's borrowing Revolving Loans pursuant to its rights
to do so, for the account of the Borrower, under Section 2.22 of the Revolving
Credit Agreement;

          (j)  any other action or circumstances that might otherwise constitute
a defense available to, or a legal or equitable discharge of, any surety,
guarantor or pledgor; or

          (k)  the fact that any of the Obligations or the Guaranty Liabilities
may become due or payable in connection with or by reason of any agreement or
transaction that may be illegal, invalid, or unenforceable in whole or in part;
it being agreed by Guarantors that the Guaranty Liabilities shall not be
discharged.

     2.3  DEMAND BY AGENT.  In addition to the terms of the guaranty set forth
in Sections 2.1 and 2.2, and in no manner imposing any limitation on such terms,
it is expressly understood and agreed that, if the Obligations are declared to
be or otherwise become immediately due and


                                       -7-
<PAGE>

payable, then Guarantors shall, upon demand in writing therefor by Agent to
Guarantors, or either one of them, immediately pay the Guaranty Liabilities to
Agent, for its own account and for the benefit of Banks, to be credited and
applied upon the Obligations.  Payment shall be in immediately available funds
to an account designated by Agent or at the address set forth herein for the
giving of notice to Agent or at any other address that may be specified in
writing from time to time by Agent.  This Section shall in no way affect Agent's
and any Bank's right to resort to the Collateral without demand, as provided in
Section 6.  Any payment received by Agent with respect to the Obligations shall
reduce the Guaranty Liabilities by the amount of such payment.

     2.4  GUARANTOR WAIVERS.  In addition to any other waivers contained herein,
Guarantors, jointly and severally, waive and agree as follows:

          (a)   each Guarantor expressly waives any right it may now or in the
future have to require Agent or any Bank to, and neither Agent nor any Bank
shall have any liability to, first pursue or enforce its rights and remedies
against Borrower, any of Borrower's properties or assets, the Collateral, or any
other security, guaranty, or pledge that may now or hereafter be held by Agent
for its benefit or the benefit of Banks for the Obligations or for the Guaranty
Liabilities, or to apply such security, guaranty, or pledge to the Obligations
or to the Guaranty Liabilities, or to pursue any other right or remedy in
Agent's or any Bank's power that such Guarantor may or may not be able to pursue
itself and that may lighten such Guarantor's burden, before proceeding against
the Collateral.  Each Guarantor agrees that any notice or directive given at any
time to Agent that is inconsistent with the waiver in the immediately preceding
sentence shall be null and void and may be ignored by Agent, and, in addition,
may not be pleaded or introduced as evidence in any litigation or other dispute
resolution procedure relating to this Guaranty for the reason that such pleading
or introduction would be at variance with the written terms of this Guaranty,
unless Agent have specifically agreed otherwise in writing.  Each Guarantor
shall remain liable for the Guaranty Liabilities, notwithstanding any judgment
Agent may obtain for the benefit of Agent or Banks against Borrower, any other
guarantor of the Obligations, or any other Person, or any modification,
extension, or renewal with respect thereto.


                                       -8-
<PAGE>

          (b)  Each Guarantor has entered into this Guaranty based solely upon
its independent knowledge of Borrower's financial condition and such Guarantor
assumes full responsibility for obtaining any further information with respect
to Borrower or the conduct of its business.  Each Guarantor represents that it
is now, and during the terms of this Guaranty will be, responsible for
ascertaining the financial condition of Borrower.  Each Guarantor hereby waives
any duty on the part of Agent or any Bank to disclose to such Guarantor, and
agrees that it is not relying upon nor expecting Agent or any Bank to disclose
to it, any fact known or hereafter known by Agent or any Bank relating to the
operation or condition of Borrower or its business or relating to the existence,
liability, or financial condition of any other guarantor of the Obligations.
Each Guarantor knowingly accepts the full range of risk encompassed in a
contract of guaranty, which risk includes the possibility that the Borrower may
incur Obligations after its financial condition or its ability to pay its debts
as they mature has deteriorated.

          (c)  Neither Agent nor any Bank shall be under any liability to
marshal any assets in favor of Guarantors or in payment of any or all of the
Obligations or Guaranty Liabilities.

          (d)  Each Guarantor hereby waives:  (i) presentment, demand, protest,
notice of acceleration, dishonor, non-payment, protest, or any delay related
thereto, with respect to any instruments or documents relating to the
Obligations or the Guaranty Liabilities, except as specifically provided in
Section 2.3; (ii) notice of any extension, modification, renewal, or amendment
of any of the terms of the Revolving Credit Agreement or any other Related
Document relating to the Obligations or the Guaranty Liabilities; (iii) notice
of the occurrence of any Default or Event of Default with respect to the
Obligations, the Guaranty Liabilities, or the Collateral; and (iv) notice of any
exercise or non-exercise by Agent or any Bank of any right, power, or remedy
with respect to the Obligations, the Collateral, or the Guaranty Liabilities.

          If Agent may, under applicable law, proceed to realize its benefits
under any Related Document giving Agent a Lien for the ratable benefit of Agent
and each Bank upon any Collateral, whether owned by Borrower or by any other
Person, either by judicial foreclosure or by nonjudicial sale or enforcement,
Agent may, at its sole option, determine which of its remedies or rights it may


                                       -9-
<PAGE>

pursue without affecting any of its rights and remedies under this Guaranty.
If, in the exercise of any of its rights and remedies, Agent shall forfeit any
of its rights or remedies under any Related Document, including obtaining a
deficiency judgment against Borrower or any other Person, whether because of any
applicable laws pertaining to "election of remedies," anti-deficiency rules, or
the like, each Guarantor hereby consents to such action by Agent and waives any
claim based upon such action.  Any election of remedies that results in the
denial or impairment of the right of Agent to seek a deficiency judgment against
Borrower shall not impair such Guarantor's obligations under this Guaranty.  In
the event Agent shall bid at any foreclosure or trustee's sale or at any public
or private sale permitted by law or the Related Documents, Agent may bid all or
less than the amount of the Obligations or the Guaranty Liabilities and the
amount of such bid need not be paid by Agent but shall be credited and applied
as set forth in Section 8.  The amount of the successful bid at any such sale,
whether Agent or any other party (including Guarantors) is the successful
bidder, shall be deemed to be PRIMA FACIE evidence of the fair market value of
the Collateral and the amount remaining after application of such bid amount in
the manner set forth in Section 8 shall be deemed to be PRIMA FACIE evidence of
the amount of the Obligations guaranteed under this Guaranty, notwithstanding
that any present or future law or court decision or ruling may have the effect
of reducing the amount of any deficiency claim to which Agent might otherwise be
entitled but for such bidding at any such sale.

          (e)  Each Guarantor agrees and represents that the Obligations are and
shall be incurred by Borrower, and that the Guaranty Liabilities are and shall
be incurred by Guarantors, for business and commercial purposes only.  Each
Guarantor agrees that any claim of Agent or any Bank against such Guarantor
arising out of this Guaranty arises out of the conduct by that Guarantor of its
trade, business, or profession.  Each Guarantor undertakes all the risks
encompassed in the Revolving Credit Agreement and the other Related Documents as
they may be now or are hereafter agreed upon by Agent, Banks and Borrower.
Agent, in such manner and upon such terms and at such time as it deems best, and
with or without notice to Guarantors, may release, add, subordinate or
substitute security for the Obligations or the Guaranty Liabilities.

          (f)  Each Guarantor waives and agrees that it shall not at any time
insist upon, plead, or in any manner


                                      -10-
<PAGE>

whatever claim or take the benefit or advantage of, any appraisal, valuation,
stay, extension, or redemption laws, or exemption, whether now or at any time
hereafter in force, which may delay, prevent, or otherwise affect the
performance by such Guarantor of the Guaranty Liabilities or the enforcement by
Agent of this Guaranty.

          (g)  A separate action or actions may be brought and prosecuted by
Agent against, either or both Guarantors whether or not an action is brought
against Borrower, or whether Borrower are joined in any such action or actions.
Without limiting the generality of the foregoing, each Guarantor expressly
waives the benefit of any statute of limitation affecting the Obligations and
expressly agrees that the running of a period of limitation on, or Agent's delay
or omission in, any action by Agent against Borrower or for the foreclosure of
any lien or the enforcement of any security interest in the Collateral shall not
exonerate or affect such Guarantor's liability to pay and perform the Guaranty
Liabilities.

     2.5  WAIVERS UNDER STATUTES.  Each Guarantor expressly acknowledges that:

          (a)  If Borrower defaults in the payment or performance of the
Obligations and Guarantors pay to Agent all or part of the Obligations,
Guarantors would have a right to proceed against Borrower to the extent of the
Obligations so paid by Guarantors and to have the benefit of any security held
by Agent, for the ratable benefit of Agent and Banks, for the Obligations to the
extent of the Obligations so paid by Guarantors.  Such right is commonly known
as the "right of subrogation."

          (b)  If Borrower defaults in the payment or performance of the
Obligations, Agent, among other things, may foreclose upon any real property
security by means of judicial action or by non-judicial action commonly known as
a "non-judicial foreclosure," "trustee's sale" or "power of sale foreclosure."

          (c)  If Borrower so defaults and Agent sells any real property
security by means of a non-judicial foreclosure, trustee's sale or power of sale
foreclosure, Guarantors' right of subrogation to proceed against Borrower would
be extinguished by the operation of California Code of Civil Procedure ("CCP")
Section 580d or similar laws, and, in such case, Guarantors might have a defense
against payment under this Guaranty.


                                      -11-
<PAGE>

          (d)  If Borrower so defaults and Agent sells any real property
security by means of judicial action, Guarantors' right to proceed against
Borrower might be limited by the operation of CCP Section 580a or similar laws,
in which case Guarantors might have a complete or partial defense against
payment under this Guaranty.

          Nevertheless, each Guarantor expressly, knowingly and intentionally
waives and relinquishes any and all rights, defenses or benefits such Guarantor
might have under CCP Sections 580a or 580d or similar laws.  In addition, each
Guarantor also expressly, knowingly and intentionally waives and relinquishes
any and all rights, defenses or benefits such Guarantor may have based upon an
election of remedies by Agent which in any manner impairs, affects, reduces,
releases, destroys and/or extinguishes that Guarantor's subrogation rights
and/or that Guarantor's rights to proceed against Borrower and/or against any
other person or any security for the Guaranty Liabilities by way of subrogation,
indemnity, contribution, reimbursement or otherwise.  In particular, each
Guarantor agrees that this Guaranty will remain fully effective and such
Guarantor will be liable to Agent for any Guaranty Liabilities even if Agent
sells real property security for the Obligations by non-judicial foreclosure,
trustee's sale or power of sale foreclosure and the effect of such sale is to
prevent such Guarantor from taking any action against Borrower to recover any
amounts paid by such Guarantor to Agent under this Guaranty or otherwise limits
or destroys such Guarantor's right of subrogation.

          Each Guarantor also agrees that this Guaranty will remain fully
effective and such Guarantor will be liable to Agent for any Guaranty
Liabilities even if Agent sells real property by judicial foreclosure action and
such Guarantor's rights against Borrower are limited by the operation of CCP
Sections 580a or 580d or similar laws.

     2.6  WAIVERS OF DEFENSES.   Each Guarantor waives any defense based upon or
arising by reason of:  (a) any disability or other defense of Borrower or any
other Person; (b) the cessation of liability or limitation from any cause
whatsoever of the Obligations or any portion thereof, other than payment in
full; (c) any lack of authority of any agent or other Person acting or
purporting to act on behalf of Borrower, or any defect in the formation of
Borrower; (d) the application by Borrower of the proceeds of the Obligations or
any other obligation of Borrower to Agent or Banks for purposes other than the


                                      -12-
<PAGE>

purposes represented to, or intended or understood by, Agent, Banks or
Guarantors; (e) any act or omission by Agent or any Bank that directly or
indirectly results in or aids the discharge of Borrower or any portion of the
Obligations or any other obligation of Borrower to Agent or Banks by operation
of law or otherwise; or (f) any modification of the Obligations or any other
obligation of Borrower to Agent or Banks in any form whatsoever, including the
renewal, extension, acceleration or other change in time for payment of the
Obligations, or other change in the terms of the Obligations or any part
thereof, including increase or decrease of the rate of interest thereon.  This
Guaranty shall remain in full force and effect notwithstanding any release of
the Borrower by the Banks from liability given in connection with or pursuant to
(i) the Manager Option Agreement, (ii) that certain Agreement to Provide Notice
of Non-Liability, dated as of September 15, 1995, among the Bonding Company, the
Agent and the Managers, or (iii) the Collateral Intercreditor Agreement.

          Without limiting the generality of the foregoing, each Guarantor
waives any defenses or rights arising under California Civil Code sections 2795,
2808, 2809, 2810, 2815, 2819 through 2825 (inclusive), 2832, 2839, 2845 through
2850 (inclusive), and 2855 or any similar laws.

     2.7  BENEFITS OF GUARANTY.  The provisions of this Guaranty are for the
benefit of Agent and the Banks and their respective successors, transferees,
endorsees, and assigns, and nothing herein shall impair, as between Borrower,
Agent, and Banks, the Obligations.  No such transfer, endorsement, or assignment
shall increase or diminish any of the Guaranty Liabilities hereunder.  This
Guaranty binds Guarantors, and Guarantors may not assign, transfer, or endorse
this Guaranty.  In the event all or any part of the Obligations are transferred,
endorsed, or assigned by Agent or any Bank to any Person, any reference to
"Agent" or "Bank" herein shall be deemed to refer equally to such Person.

     2.8  CONTINUING GUARANTY.  Each Guarantor agrees that (a) this is a
continuing guaranty, (b) this Guaranty shall remain in full force and effect
until the Obligations are paid in full and the Guaranty Liabilities shall have
been completely satisfied, and (c) the Guaranty Liabilities hereunder shall
extend to each and every extension or renewal, if any, of the Revolving Credit
Agreement, regardless of whether the Obligations may, in successive


                                      -13-
<PAGE>

transactions, be paid, repaid, advanced, or renewed from time to time.

     2.9  SUBORDINATION.

          (a)  Each Guarantor hereby agrees that all obligations and all
indebtedness of Borrower to such Guarantor, including any and all present and
future indebtedness regardless of its nature or manner of origination now or
hereafter to become due and owing by Borrower to such Guarantor (collectively,
the "Subordinated Indebtedness"), are hereby unconditionally and forever
subordinated and postponed and shall be inferior, in all respects, to the
Obligations.

          (b)  In no circumstance shall any Subordinated Indebtedness be
entitled to any collateral security; PROVIDED, that in the event any such
collateral security exists, each Guarantor agrees that any now existing or
hereafter arising Lien upon or security interest in any of the assets of
Borrower, or any of the assets of any other guarantor of the Obligations, in
favor of such Guarantor, whether created by contract, assignment, subrogation,
reimbursement, indemnity, operation of law, principles of equity or otherwise,
shall be junior and inferior to, and is hereby subordinated in priority to any
now existing or hereafter arising Lien or security interest in favor of Agent,
for the ratable benefit of Agent and Banks, or in and against the Collateral,
regardless of the time, manner or order of creation, attachment or perfection of
the respective liens or security interests.

          (c)  Neither Guarantor shall assert, collect, accept payment on or
enforce any of the Subordinated Indebtedness or take collateral or other
security to secure payment of the Subordinated Indebtedness unless and until the
Obligations are paid in full.  Neither Guarantor shall demand payment of,
accelerate the maturity of, or declare a default or event of default under the
Subordinated Indebtedness unless and until the Obligations are paid in full.
Neither Guarantor shall cause or permit Borrower to make or give, and such
Guarantor shall not receive or accept, payment in any form (direct or indirect,
including by transfer to an affiliate or subsidiary of Borrower or such
Guarantor) on account of the Subordinated Indebtedness, make any transfers in
respect of the Subordinated Indebtedness without the express prior written
consent of the Majority Banks, or give any collateral security for the
Subordinated Indebtedness.  Any payment,



                                      -14-
<PAGE>

transfer, or collateral security so made or given by Borrower and received or
accepted by such Guarantor, without the express prior written consent of the
Majority Banks, shall be held in trust by that Guarantor for Agent, for the
account of Agent and Banks, and that Guarantor shall immediately turn over, in
kind, any such payment to Agent for application in reduction of, or (in the case
of property other than cash) as security for, the Guaranty Liabilities.

     2.10  SUBROGATION.

          Neither Guarantor will exercise any rights which it may acquire by way
of subrogation under this Guaranty, by any payment made hereunder or otherwise,
until all the Obligations shall have been paid in full.  If any amount shall be
paid to either Guarantor on account of such subrogation rights at any time when
all the Obligations shall not have been paid in full, such amount shall be held
in trust for the benefit of Agent, for the ratable benefit of Agent and Banks,
and shall forthwith be paid to Agent to be credited and applied upon the
Obligations, whether matured or unmatured, in accordance with the terms of the
Revolving Credit Agreement.  If (i) either Guarantor shall make payment to Agent
of all or any part of the Obligations and (ii) all the Obligations shall be paid
in full, Agent will, at such Guarantor's request, execute and deliver to that
Guarantor appropriate documents, without recourse and without representation or
warranty, necessary to evidence the transfer by subrogation to that Guarantor of
an interest in the Obligations resulting from such payment by that Guarantor.

     2.11  LIMIT OF LIABILITY.  The obligations of Guarantors under this
Guaranty shall be limited to an aggregate amount equal to the largest amount
that would not render their joint and several obligations under this Guaranty
subject to avoidance under Section 548 of the Bankruptcy Code or any comparable
provisions of any applicable state law.

     2.12  NO OFFSET, DEFENSE, OR COUNTERCLAIM.  Each Guarantor represents,
warrants and agrees that, as of the date of this Guaranty, the Guaranty
Liabilities are not subject to any offset or defense against Agent, any Bank, or
Borrower of any kind, and such Guarantor specifically waives its right to assert
any such defense or right of offset.  Each Guarantor further agrees that the
Guaranty Liabilities shall not be subject to any counterclaims,


                                      -15-
<PAGE>

offsets, or defenses against Agent, any Bank or Borrower that may arise in the
future, except for (a) any defense of prior performance or payment, or (b) any
defense based on any applicable provision of the UCC requiring that the
Collateral be disposed of in a commercially reasonable manner, which Borrower,
such Guarantor, or other guarantor of the Obligations may have or assert.

                   a.  The Company agrees to pay Premium, Indemnity, interest,
and all other amounts due hereunder without set-off or counterclaim or any

shall accrue on such due and unpaid amount at the Default Rate.

          F.   REIMBURSEMENT.  Except as set forth in Section 8.2(b) hereof
with respect to the payment of Indemnity, whenever the Surety shall sustain or
incur any losses or out-of-pocket expenses in connection with a Default, the
Company agrees to pay to such Surety, upon the Surety's demand, an amount
sufficient to compensate the Surety for all such losses and out-of-pocket
expenses.  The Surety's good faith determination of the amount of such losses
and out-of-pocket expenses, absent manifest error, shall be binding and
conclusive.  Losses subject to reimbursement hereunder shall include, without
limiting the generality of the foregoing, expenses incurred by any Surety or any
co-surety or reinsurer of the Surety.

          G.   APPLICATION OF PAYMENTS.  If some but less than all amounts due
from the Company are received by the Surety, the Surety shall distribute such
amounts in the following order of priority: FIRST, to the payment of any
Indemnity then due and payable to the Surety hereunder or under any Bond,
including, without limitation, (i) to damages, losses, and expenses incurred by
the Surety by reason of execution of any Bond, any breach hereof or of any other
Bond Document; and (ii) attorneys, fees and expenses incurred by the Surety in
the collection of amounts under this Agreement or of any Bond; SECOND, to the
payment of interest then due and payable on the  Bonds; THIRD, to the payment of

<PAGE>

all other Obligations not otherwise referred to in this Section 2.7(a) then due
and payable.

          H.  MAXIMUM RATE OF INTEREST.  In no contingency or event whatsoever
shall the aggregate of all amounts deemed interest on the accrued but unpaid
Premiums and Indemnity and charged or collected pursuant to the terms of this
Agreement or pursuant to the Bond exceed the highest rate permissible under any
law which a court of competent jurisdiction shall, in a final determination,
deem applicable thereto.  In the event that such a court determines that the
Surety charged or received interest hereunder in excess of the highest
applicable rate, the rate in effect hereunder shall automatically be reduced to
the maximum rate permitted by Applicable Law and the Surety shall promptly
refund to the Company any interest received by it in excess of the maximum
lawful rate or, if so requested by the Company, shall apply such excess to the
principal balance of the Obligations.  It is the intent hereof that the Company
not pay or contract to pay, and that the Surety not receive or contract to
receive, directly or indirectly in any manner whatsoever, interest in excess of
that which may be paid by the Company under Applicable Law.

                                      -34-
<PAGE>

Base Deficiency will exist, after giving effect to any replacement Eligible
Equipment added to Collateral in accordance with Section 5.13(e) below.

               b.  If no specific dollar value is attributed to the portion of
Eligible Equipment proposed to be removed from the Collateral in the Independent
Appraiser's Initial Report, the Company may propose an Amendment to Schedule 1.1
only if it delivers a Bonding Base Certificate, signed by the Independent
Appraiser, which shall demonstrate that, after giving effect to the removal of
the portion of Eligible Equipment proposed to be removed, no Bonding Base
Deficiency will exist, after giving effect to any replacement Eligible Equipment
added to Collateral in accordance with Section 5.13(e) below.

               c. The Company may propose an Amendment to Schedule 1.1 which
would remove a portion of cash or securities from Collateral if and only if,
after giving effect to the removal of said portion of cash or securities, no
Bonding Base Deficiency will exist.

would remove a portion of the Collateral, the Bonding Base shall be
appropriately reduced;

               e.  No amendment to Schedule 1.1 removing any portion of the

PROVIDED that all of the conditions (i) through (v) of this Section 5.13(d) are

          5. ADDITION OF COLLATERAL.  The Company may propose an amendment to
Schedule 1.1 increasing the amount of Eligible Equipment only if it delivers a
Bonding Base Certificate, signed by the Independent Appraiser, which shall state
the Value of Eligible Equipment proposed to be added to Collateral.

          The Surety will execute such proposed amendment to Schedule 1.1;
provided that each item of equipment proposed to be added to Collateral
constitutes Eligible Equipment.

          6.  MAINTENANCE OF COLLATERAL.  The Company, at its expense, shall
take all steps necessary or appropriate to maintain the Eligible Equipment which
is Collateral in a manner consistent with prudent industry practice and as
necessary to maintain the value attributed to such Eligible Equipment in the
Independent Appraiser's Initial Report.


                                      -35-
<PAGE>

In the event that any Collateral is damaged (whether by accidental occurrence or
any other event or occurrence) or is not properly maintained, or for any other
reason ceases to meet the requirements of Eligible Equipment or fails to
maintain the value attributed to such Collateral in the Independent Appraiser's
Initial Report, the entire value of said Collateral shall be subtracted from the
Bonding Base immediately; provided, however, that the decreased value of said
Collateral may be subsequently added to Collateral if the Company delivers a
Bonding Base Certificate, signed by the Independent Appraiser, which shall state
the revised Value of said Eligible Equipment.

      N. FURTHER ASSURANCES.  The Company shall promptly cure, or cause to be
cured, defects in the creation and issuance of the Bond and the execution and

and deliver to the Surety, or cause to be executed and delivered to the Surety,

          2.  Any party hereto may change the address to which notices shall be
directed under this Section 8.1 by giving ten (10) days' written notice of such
change to the other parties.

     B.  INDEMNIFICATION OF SURETY.

          1. INDEMNIFICATION.  The Company shall exonerate, indemnify, and keep
indemnified the Surety from and against any and all liability for losses and/or
expenses of whatsoever kind or nature (including, but not limited to, interest,
court costs and counsel fees) and from and against any and all such losses
and/or expenses which the Surety may sustain and incur:

                    (1) By reason of having issued, executed, or procured the
issuance or execution of any of the Bonds,

                    (2) By reason of the failure of the Company to perform or
comply with the covenants and conditions of this Agreement; or

                    (3) In enforcing the covenants and conditions of this
Agreement.

          2. PAYMENT OF INDEMNITY.  Notwithstanding anything to the contrary
herein, payment by reason of the causes specified in Section 8.2(a) shall be
made in immediately available funds to the Surety by the Company as soon as
liability exists or is asserted against the Surety, whether or not the Surety
shall have made any payment therefor.  Such payment shall be equal to the amount
of the reserve set by the Surety.  In the event of any payment by the Surety,
the Company further agrees that in any accounting between the Surety and the
Company, the Surety shall be entitled to charge for any and all disbursements
made by it in good faith in and about the matters herein contemplated by this
Agreement under the belief that it is or was liable for the sums and amounts to
disbursed, or that it was necessary or expedient to make such disbursements,
whether or not such liability, necessity or expediency existed; and that the
vouchers or other evidence of any such payments made by the Surety shall be
PRIMA FACIE evidence of the fact and amount of the liability to the Surety.

     C.  EXPENSES.  The Company agrees to promptly pay:

          1.   All reasonable out-of-pocket expenses of the Surety in connection


                                      -48-
<PAGE>

with the preparation, negotiation, execution, and delivery of this Agreement and
the other Bond Documents, the transactions contemplated hereunder and
thereunder, and the making of the initial Bond hereunder, including, but not
limited to, the fees and disbursements of counsel and consultants for the Surety
up to $2.5 million;

          2.   All reasonable out-of-pocket costs and expenses of the Surety in
connection with any restructuring, refinancing, or, "work-out" of the
transactions contemplated by this Agreement, and of obtaining performance under
this Agreement or the other Bond Documents, and all out-of-pocket costs and
expenses of collection if default is made in the payment of the Bond, which in
each case shall include fees and out-of-pocket expenses of counsel for the
Surety, and the fees and out-of-pocket expenses of any experts, agents, or
consultants of the Surety; and

(d)  All taxes, assessments, general or special, and other charges levied on, or
assessed, placed or made against any of the Collateral, the Bond Documents, or
the Obligations.

     D.    WAIVERS.  The rights and remedies of the Surety under this Agreement
and the other Bond Documents shall be cumulative and not exclusive of any rights
or remedies which they would otherwise have.  No failure or delay by the Surety,
in exercising any right shall operate as a waiver of such right.  The Surety
expressly reserves the right to require strict compliance with the terms of this
Agreement in connection with any funding of a request for a Bond.  In the event
the Surety decides to fund a request for a Bond at a time when the Company is
not in strict compliance with the terms of this Agreement, such decision by the
Surety shall not be deemed to constitute an undertaking by the Surety to fund
any further requests for Bonds or preclude the Surety from exercising any rights
available to the Surety under the Bond Documents or at law or in equity.  Any
waiver or indulgence granted by the Surety shall not constitute a modification
of this Agreement, except to the extent expressly provided in such waiver or
indulgence, or constitute a course of dealing by the Surety  at variance with
the terms of the Agreement such as to require further notice by the Surety of
the Surety's intent to require strict adherence to the terms of the Agreement in
the future.  Any such actions shall not in any way affect the ability of the
Surety, in its discretion, to exercise any rights available to it under this
Agreement or under any other agreement, whether or not the Surety is a party,
relating to the Company.

     E.    SET-OFF.  In addition to any rights now or hereafter granted under
Applicable Law and not by way of limitation of any such rights, upon the
occurrence of a Default or an Event of Default and during the continuation
thereof, the Surety and any subsequent holder or holders of the Bond is hereby
authorized by the Company at any time or from time to time, without notice to
the Company or to any other Person, any such notice


                                      -47-
<PAGE>

being hereby expressly waived, to set-off and to appropriate and apply any and
all deposits (general or special, time or demand, including, but not limited to,
Indebtedness evidenced by certificates of deposit, in each case whether matured
or unmatured) and any other Indebtedness at any time held or owing by the Surety
or such holder to or for the credit or the account of the Company, against and
on account of the Obligations, irrespective of whether or not (a) the Surety or
the holder of the Bond shall have made any demand hereunder or (b) the Surety
shall have declared the principal of and interest on the Bonds and the Bond and
other amounts due hereunder to be due and payable as permitted by Section 7.2
and although said obligations and liabilities, or any of them, shall be
contingent or unmatured.

     F.    ASSIGNMENT.

          1.   The Company may not assign or transfer any of its rights or
obligations hereunder, under the Bond or under any other Bond Document without
the prior written consent of the Surety.

          2.   The Surety may at any time assign all of its rights hereunder,
under the Bond and under any other Bond Document.  The Surety may at any time
enter into participations with one or more other co-sureties or other Persons
pursuant to which the Surety may participate its interest under this Agreement
and the other Bond Documents, including, its interest in any particular Bond or
portion thereof.  In the event the Surety procures the execution of the Bonds by
the other sureties, or executes the Bonds, with co-sureties, or reinsures any
portion of said Bonds with reinsuring sureties, then all the terms and
conditions of this Agreement shall inure to the benefit of such other sureties,
co-sureties and reinsuring sureties, as their interest may appear.

     G. COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

     H.  GOVERNING LAW.  This Agreement and the Bond Documents shall be
construed in accordance with and governed by the laws of the State of New York
without regard to its conflict of laws doctrine.

     I.  SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable shall be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof in that
jurisdiction or affecting the validity or enforceability of such provision in
any other jurisdiction.

     J.  HEADINGS.  Headings used in this Agreement are for convenience only and
shall


                                      -48-
<PAGE>

not be used in connection with the interpretation of any provision hereof.

     K.  ENTIRE AGREEMENT.  Except as otherwise expressly provided herein, this
Agreement and the other documents described or contemplated herein embody the
entire Agreement and understanding among the parties hereto and thereto and
supersede all prior agreements, understandings, and conversations relating to
the subject matter hereof and thereof.  The parties explicitly acknowledge that
any indemnification agreement existing as of the date hereof between the Surety
and the Company or any of its Affiliates shall not apply to any Bonds issued
pursuant to this Agreement.  The Company represents and warrants to the Surety
that it has read the provisions of this Section 8.11 and discussed the
provisions of this Section 8.11 and the rest of the Bond Agreement with counsel
for the Company, and the Company acknowledges and agrees that the Surety is
expressly relying upon such representations and warranties of the Company (as
well as the other representations and warranties of the Company set forth in
Article 4 hereof) in entering into this Agreement.

     L. HOMESTEAD. The Company hereby waives, so far as their respective
obligations under this Agreement are concerned, all rights to claim any of their
property, including their respective homesteads, as exempt from levy, execution,
sale or other legal process under the laws of any State, Territory, or
Possession.

     M. SETTLEMENTS.  The Surety shall have the right to adjust, settle or
compromise any claim, demand, suit or judgment upon the Bonds, unless the
Company shall request the Surety to litigate such claim or demand, or to defend
such suit, or to appeal from such judgment, and shall deposit with the Surety,
at the time of such request, cash or collateral satisfactory to the Surety in
kind and amount, to be used in paying any judgment or judgments rendered or that
may be rendered, with interest, costs, expenses and attorneys' fees, including
those of the Surety.

     N.  AMENDMENT; WAIVER.

 Neither this Agreement nor any term hereof may be amended orally, nor may any
provision hereof be waived orally but only by an instrument in writing signed by
the Surety and the Company.

     O.  OTHER RELATIONSHIPS.  No relationship created hereunder or under any
other Bond Document shall in any way affect the ability of the Surety to enter
into or maintain business relationships with the Company, or any of its
Affiliates, beyond the relationships specifically contemplated by this Agreement
and the other Bond Documents.

     P.  PRONOUNS.  The pronouns used herein shall include, when appropriate,

sentences shall conform thereto.

XXII.     JURISDICTION, VENUE AND WAIVER OF JURY TRIAL

     A.  JURISDICTION AND SERVICE OF PROCESS.  For purposes of any legal action
or proceeding brought by the Surety with respect to this Agreement or any other
Bond Document, the Company hereby irrevocably submits to the personal

Columbia.  The consent to jurisdiction herein shall be exclusive.  The Company
further irrevocably consents to service of process in any such action or
proceeding by the mailing of copies thereof by registered or certified mail to
the Company at the address set forth above, such service to become effective

service of legal process cannot be made in the manner described above, such
service may be made in such manner as permitted by law.

     B.  CONSENT TO VENUE.  The Company hereby irrevocably waives any objection
it would make now or hereafter for the laying of venue of any suit, action, or
proceeding arising out of or relating to this Agreement or any other Bond
Document brought in the federal courts of the United States of America sitting
in Washington, D.C. and hereby irrevocably waives any claim that any such suit,
action, or proceeding has been brought in an inconvenient forum.

     C.  WAIVER OF JURY TRIAL.  THE COMPANY AND THE SURETY WAIVE, AND OTHERWISE
AGREE NOT TO REQUEST, A TRIAL BY JURY IN ANY COURT AND IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM OF ANY TYPE IN WHICH THE COMPANY, THE SURETY, OR ANY OF THEIR
RESPECTIVE SUCCESSORS IS A PARTY, AS TO ALL MATTERS AND THINGS ARISING DIRECTLY
OR INDIRECTLY OUT OF THIS AGREEMENT, THE BOND OR THE OTHER BOND DOCUMENTS AND

among American Passenger Rail Car Company, L.L.C., a Delaware limited liability
company (the "Buyer"), Morrison Knudsen Corporation, an Ohio corporation

Knudsen Corporation, a Delaware corporation ("MK Delaware"), and each of the
entities listed on Schedule 1 hereto (collectively, MK Delaware and the entities
listed on Schedule 1 hereto, the "MK Affiliates").

          WHEREAS, MK Delaware is the sole owner, of record and beneficially, of
all of the issued and outstanding capital stock of the Seller and has Affiliates
(as hereinafter defined) including the entities listed in Schedule 1 hereto;

          WHEREAS, the Seller, among other things, conducts a public
transportation manufacturing business, which provides  engineering services and
manufactures and refurbishes commuter passenger and transit railcars for various
municipalities and other governmental entities pursuant to the Transit Division
Contracts (as hereinafter defined) (the "Business");

          WHEREAS, the Seller and its advisors have attempted to find a
purchaser for the Business and anticipated having to pay potential transferees
of the Purchased Assets (as defined below) to accept them, but, due to potential
liabilities and other concerns, have been unsuccessful in concluding any such
transaction;

          WHEREAS, at the request of the Seller, Fidelity and Deposit Company of
Maryland, on its own behalf and on behalf of its co-sureties and reinsurers
(collectively, the "Sureties"), executed and delivered that certain guarantee
(the "$25,000,000 Guarantee") dated as of July 31, 1995, guaranteeing certain
obligations of the Seller, up to a maximum principal amount of Twenty-five
Million Dollars ($25,000,000.00), under that certain credit agreement (the
"Previous Credit Agreement") described in Schedule R1, conditioned on certain
principal terms and conditions set forth in the T-Co Term Sheet (as hereinafter
defined), executed contemporaneously with the $25,000,000 Guarantee, which
principal terms and conditions provided, among other things, that the Seller
would transfer and assign to the Buyer the assets used to conduct the Business
in accordance with the terms of this Agreement;


                                        2
<PAGE>

          WHEREAS, certain financial institutions that are lenders to the Seller
(the "Banks") extended to the Seller financing (the "New Financing"), subject to
and conditioned on certain principal terms and conditions set forth in the T-Co
Term Sheet, executed contemporaneously with the extending of such financing,
which principal terms and conditions provided, among other things, that the
Seller would transfer and assign to the Buyer the assets used to conduct the
Business in accordance with the terms of this Agreement.

          WHEREAS, if the transactions contemplated by this Agreement did not
occur, such failure to consummate the transactions contemplated by this
Agreement would constitute an event of default with respect to the New Financing
and all original financing provided by the Banks to or for the benefit of the
Seller, entitling the Banks to accelerate such financing and to enforce certain
rights and remedies against the Seller, including the right to enforce the
Banks' security interests in certain assets and property of the Seller;

          WHEREAS, the Sureties have agreed, at the request of the Seller and
the Buyer, to enter into an agreement (the "New Bonds Agreement"), at Closing,
to issue the bond or bonds described in the New Bonds Agreement (the "New
Bonds"), on the terms and conditions set forth in the New Bonds Agreement,
subject to, and conditioned upon, the Buyer agreeing to assume the Buyer
Obligations, certain banks and financial institutions extending new credit and
the Seller transferring and assigning the Purchased Assets to the Buyer
contemporaneously with the entering into of the New Bonds Agreement, on the
terms and conditions herein set forth;

          WHEREAS, pursuant to Section 2.05 of this Agreement, the Buyer will
pay the amount set forth on Exhibit 2.05(a) to the Seller as partial
consideration for the Purchased Assets;

          WHEREAS, a financial advisor has provided an opinion as to the
fairness of the transaction contemplated by this Agreement;

          WHEREAS, since the Seller believes that the New Financing and the New
Bonds are necessary for the continued operation and viability of the Seller's
remaining business and that the value of such New Financing and New Bonds,
together with the cash payment to be made by the Buyer pursuant to Section 2.05
is at least equivalent to the value of the Purchased Assets, and, further, to
avoid the acceleration of the Seller's existing financing and the exercise of
the Banks' rights and remedies against the Seller and its assets and properties
as aforesaid, the Seller desires to sell the Purchased Assets to the Buyer, upon
the terms and subject to the conditions of this Agreement; and

          WHEREAS, the Buyer desires to purchase the Purchased Assets and has


                                        3

agreed to assume the Buyer Obligations, upon the terms and subject to the

Closing Statement of Net Assets To Be Sold and the draft of the Closing Deloitte
& Touche Report and the Agreed Upon Procedures Report (and any employees of the
Seller and officers of the Buyer of the level of controller or above shall be
entitled to access to Deloitte & Touche's work papers prepared in connection
with its draft reports) and to submit in writing any suggestions for changes
thereto to Deloitte & Touche.  Any suggestions submitted to Deloitte & Touche
shall concurrently be submitted to the Buyer or the Seller, as applicable.  For
a period of fifteen (15) Business Days after the expiration of such fifteen (l5)
Business Day period, the Buyer and the Seller shall consult with each other and
with Deloitte & Touche to determine if any such suggested changes may be
resolved to the mutual satisfaction in writing of the Buyer and the Seller.

          Within fifteen (15) Business Days after the Report Delivery Date, the
Buyer shall deliver to the Seller a statement identifying (i) any disbursements
made from July 1, 1995 to the Closing Date by or on behalf of the transit
division of the Seller that the Buyer contends were not Necessary for the
Business (each, a "Buyer Reimbursable Disbursement") and (ii) any overhead
allocated by the Seller to its transit division from July 1, 1995 to the Closing
Date that the Buyer contends constitutes Excluded Overhead that have not been
previously reimbursed to the Buyer or the transit division of the Seller and
either applied as described in Section 3.24 of this Agreement or acquired by the
Buyer at the Closing (a "Buyer Reimbursable Overhead Payment").  The Seller has
determined that there were checks aggregating $4,232,069.94 that had been
written prior to July 1, 1995 but did not clear until on or after July 1, 1995.
Based on such determination, for purposes of this Section 2.07, the parties
agree that $3,239,967.63 of that amount is to be considered a post-July 1, 1995
disbursement and that $992,102.31 of that amount is to be considered a pre-July
1, 1995 disbursement.

          Within fifteen (15) Business Days after the Report Delivery Date, the
Seller shall deliver to the Buyer a statement identifying (i) any disbursements
made from July 1, 1995 to the Closing Date by or on behalf of the Seller
(excluding its transit division) or any MK Affiliate that the Seller contends
were Necessary for the Business and that have not been previously reimbursed to
the Seller (excluding its transit division) or any MK Affiliate (a "Seller
Reimbursable Disbursement") and (ii) any overhead items on the 1995 Proposed
Overhead Budget allocable to the Seller's transit division from July 1, 1995 to
the Closing Date that does not constitute Excluded Overhead that has not been
previously reimbursed to the Seller (excluding its transit division) or any MK
Affiliate (a "Seller Reimbursable Overhead Payment").  The Buyer and Seller
shall have fifteen (15) Business Days from the


                                       20
<PAGE>

date of delivery of the foregoing statements to reach agreement as to the amount
required to be paid by either party to the other party in accordance with the
foregoing statements.  To the extent the Buyer and the Seller agree on the
amounts required to be paid by either to the other, the party owing such amount
shall pay such amount to the other within five (5) Business Days after reaching
such agreement.

          If the Buyer and Seller are unable to reach agreement with respect to
any suggested changes to the Closing Statement of Net Assets To Be Sold (the
"Unresolved Changes") and/or amounts required to be paid by either party to the
other by the end of the applicable periods specified above, then the matter(s)
shall be submitted to arbitration in accordance with section 9.04 and 10.04
hereof.  At the completion of the arbitration process, the resolution of the
Unresolved Changes shall be reflected in the Closing Statement of Net Assets To
Be Sold, which statement, and the executed Closing Deloitte & Touche Report and
the executed Agreed Upon Procedures Report, shall be final and binding upon the
parties hereto.  In addition, the decision of the arbitrator as to the amount of
any Buyer Reimbursable Disbursement, Buyer Reimbursable Overhead Payment, Seller
Reimbursable Disbursement or Seller Reimbursable Overhead Payment shall be final
and binding upon the parties hereto.

          All fees, costs, and expenses (including attorneys' fees and expenses)
incurred by the party that prevails in any such arbitration may be assessed
against the party that does not prevail in such arbitration.  This provision for
arbitration shall be specifically enforceable by the parties.  No statement made
in the footnotes to either Net Assets Statement shall expand or reduce the
Liabilities that come within the definition of Buyer Obligations as set forth in
this Agreement.

          Notwithstanding any other provision of this Section 2.07, neither the
Buyer nor the Seller shall be obligated to pay any amount to the other pursuant
to Section 2.07 or Section 2.08 based on the audit of the Closing Statement of
Net Assets To Be Sold or the Agreed Upon Procedures Report, except for Buyer
Reimbursable Disbursements, Buyer Reimbursable Overhead Payments, Seller
Reimbursable Disbursements, and Seller Reimbursable Overhead Payments.

          For purposes of this Section 2.07, (i) "Necessary for the Business"
means necessarily incurred in performance of the Transit Division Contracts in
the ordinary course of the Business, and (ii) "Excluded Overhead" means "401(k)
and SERP Expenses", "Legal and Audit Services", "Professional and Consulting
Services", and "other Outside Services" as those terms are used in the 1995
Proposed Overhead Budget attached as an exhibit to the Indemnification and
Reimbursement Agreement.

          (b) The Buyer shall provide all reasonable assistance and cooperation
of its


                                       21
<PAGE>

employees and representatives to assist in the preparation of the Closing
Statement of Net Assets To Be Sold, and the Seller shall require Deloitte &
Touche to allow the Buyer and its auditors to examine all of the auditors' work
papers (including observation of inventories, review of open contracts and all
memoranda prepared in connection with the completion of the Closing Statement of
Net Assets To Be Sold and the preparation of the Closing Deloitte & Touche
Report and the Agreed Upon Procedures Report), schedules and other documents
prepared in connection with the preparation of the Closing Statement of Net
Assets To Be Sold.  The right to examine work papers, schedules and documents
shall continue after completion of the examination.

          2.08.  REIMBURSEMENTS.

          (a)  To the extent that the arbitrator determines that there is any
Buyer Reimbursable Disbursement, Buyer Reimbursable Overhead Payment, Seller
Reimbursable Disbursement, or Seller Reimbursable Overhead Payment, the Seller
shall pay the amount of any Buyer Reimbursable Disbursement and Buyer
Reimbursable Overhead Payment to the Buyer, and the Buyer shall pay the amount
of any Seller Reimbursable Disbursement and Seller Reimbursable Overhead Payment
to the Seller, within fifteen (15) days of the completion of the arbitration.

          (b) Any payments pursuant to this Section 2.08 shall be made in
immediately available funds by wire transfer to an account designated by the
recipient at least two (2) Business Days prior to the payment date.  The amount
of any payment to be made pursuant to this Section 2.08 shall bear interest from
and including the Closing Date (but excluding the date of payment) through the
date of payment in full, at a rate per annum equal to the Reference Rate.  Such
interest shall be payable at the same time as the payment to which it relates
and shall be calculated daily on the basis of a year of 365 days.

enforceable against the Seller in accordance with its terms (i) except as
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws now or hereafter in effect relating to or affecting

Schedule, such financial statements have been prepared based on the books and
records of the Seller and have been prepared in accordance with GAAP, consistent
with past practice.  All management letters and all other letters, reports and
other documents delivered to the Seller or any of its Affiliates by Deloitte &

          3.09.  PROPERTIES; LEASES; TANGIBLE ASSETS.

          (a) Except as disclosed in Section 3.09(a) of the Disclosure Schedule,

building restrictions, or any other rights of others or other adverse interests
of any kind, including leases, chattel mortgages, conditional sales contracts,
collateral security arrangements and other title or interest retention
arrangements (collectively, "Encumbrances"), except Permitted Liens.  Except as
disclosed in Section 3.09(a) of the Disclosure Schedule, to the Seller's
knowledge, there are no governmental assessments, charges or claims (other than
Taxes) the payment of which is not yet due, which would create a Lien on any of

          (c) the Seller does not own any real property that is Attributable to
the Business.

          (d) Section 3.09(d) of the Disclosure Schedule sets forth all personal

Leases" and those leases relating to personal property and indicating where
appropriate those leases which have been recorded for tax, protection of title
of interest, or other purposes) entered into in connection with the Business
(the "Leases").  With respect to the Real Property Leases and the Leases, there
exist no defaults or violations by the Seller or, to the Seller's knowledge, any
default or violation or threatened default or violation by any third party
thereunder that has affected or could reasonably be expected to affect the

<PAGE>

representations set forth in this Section 3.09(d) if the Seller fails to include

with respect to any property subject to any of the Real Property Leases (the
"Real Property"), to the knowledge of the Seller, there exists no applicable
restrictive covenant, zoning ordinance, building code, use or occupancy
restriction, or any violation of any such ordinance, code or restriction, or any
condemnation action or proceeding with respect thereto, that will interfere with
the assignment thereof to the Buyer pursuant hereto or will materially interfere
with the enjoyment thereof by the Buyer following the Closing in the conduct of
the Business.

          (f) Except as disclosed in Section 3.09(f) of the Disclosure Schedule,
to the knowledge of the Seller, none of the buildings and structures located on
any Real Property nor any appurtenances thereto or equipment thereon, nor the
operation or maintenance thereof, violates any restrictive covenants or
encroaches on any property owned by others, except for such violations or
encroachments, if any, that do not have a Material Adverse Effect.  To the
knowledge of the Seller, no condemnation proceeding is pending or threatened
which would preclude or impair the use of any Real Property for the uses
permitted under the Real Property Leases.  No expropriation proceeding is
pending, or to the Seller's knowledge threatened, with respect to the Business
or any of the Purchased Assets.

          3.10.  SUFFICIENCY OF PURCHASED ASSETS.  The Purchased Assets

thereunder) as to which either (i) notices would be required to be filed with
the PBGC; or (ii) penalties have not been waived under PBGC Technical Update 95-
3.  The PBGC has not instituted proceedings to terminate any such plan pursuant
to Subtitle 1 of Title IV of ERISA, and there is no pending or threatened
action, proceeding or investigation under Title IV of ERISA against or involving
any such plan.  There are no liens pending against the Seller or any ERISA

                      INDEMNIFICATION OF BUYER INDEMNITEES
                              FOLLOWING THE CLOSING

          9.01.  AGREEMENT TO INDEMNIFY.  If the Closing occurs, the Buyer and
its Affiliates (collectively, the "Buyer Indemnitees") shall be indemnified and
held harmless to the extent set forth in this Article IX by the Seller in
respect of any and all Damages incurred by any Buyer Indemnitee as a result of
each of the following:

     (a) any breach of any representation or warranty made by the Seller or any

Disclosure Schedule or other schedule of the Seller hereto;
     (b) the breach or failure to perform by the Seller after the Closing Date
of any of the covenants, agreements or obligations of the Seller contained in
this Agreement or the Conveyance Documents, or in any exhibit or schedule,
hereto;
     (c) any Liabilities of the Seller, other than the Buyer Obligations;
     (d) any Environmental Liability of the Buyer or the Seller that arose out

approval, authorization, certificate, consent, license, order, permit or other
similar authorization of any Governmental Authority or other Person required by

     (e) any claim asserted by any Person (other than claims with respect to

any failure or alleged failure of the Seller to pay any amounts due creditors of
the Seller as of the Closing Date under any bulk sales or similar laws
(including Tax laws relating to sales in bulk); and
     (f) all actions, suits, proceedings, demands, assessments, judgments, costs
and expenses incident to any of the foregoing.

          9.02.  SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  All
representations and warranties made by the Seller in this Agreement or in any
exhibit hereto, the Disclosure Schedule or other schedule hereto, shall survive
the Closing for a period of two years.  Notwithstanding any investigation or

complete the Closing, each party shall be entitled to rely upon the
representations and warranties set forth herein and therein.  Any


                                       48
<PAGE>

claim for indemnification pursuant to Section 9.02(a) made prior to the end of
the survival period shall continue to be subject to indemnification in
accordance with this Agreement.  All covenants of the Seller contained in this
Agreement or in any exhibit or schedule hereto shall survive the Closing.

          9.03.  CLAIMS FOR INDEMNIFICATION.  If any Buyer Indemnitee shall
believe that such Buyer Indemnitee is entitled to indemnification pursuant to
this Article IX in respect of any Damages, such Buyer Indemnitee shall give the
Seller prompt written notice thereof.  Any such notice shall set forth in
reasonable detail and to the extent then known the basis for such claim for
indemnification.  The failure of such Buyer Indemnitee to give notice of any
claim for indemnification promptly shall not adversely affect such Buyer
Indemnitee's right to indemnity hereunder except to the extent that such failure
adversely affects the right of the Seller to assert any reasonable defense to
such claim.  The Seller shall have twenty (20) Business Days following its
receipt of such notice either (y) to acquiesce in such claim by giving such
Buyer Indemnitee written notice of such acquiescence or (z) to object to the
claim by giving such Buyer Indemnitee written notice of the objection.  If the
Seller acquiesces in such claim or the Seller does object thereto within such
twenty (20) Business Day period, such Buyer Indemnitee shall be entitled to be
indemnified for all Damages incurred by such Buyer Indemnitee in respect of such
claim.  If the Seller timely objects to such claim and such Buyer Indemnitee and
the Seller is unable to resolve their dispute within ten (10) Business Days
following such objection (or such additional period of time as may be mutually
agreed to by Buyer Indemnitee and the Seller), the claim shall be submitted
immediately to arbitration pursuant to Section 9.04.

          9.04.  ARBITRATION OF DISPUTES RELATING TO INDEMNIFICATION.

          (a) Any dispute between any Buyer Indemnitee and the Seller under this
Article IX shall be resolved by one arbitrator in accordance with the procedures
set forth in this Section 9.04.  Within ten (10) Business Days after expiration
of the ten (10) Business Day period referred to in Section 9.03, each of (y) the
Seller and (z) the relevant Buyer Indemnitee(s) shall designate a mutually
acceptable arbitrator who is, in any such case, not affiliated with any party in
interest to such arbitration and who has substantial professional experience
with regard to corporate legal matters.  If the Seller and the relevant Buyer
Indemnitee(s) fail to agree upon such arbitrator within such ten (10) Business
Day period, the arbitrator shall be appointed by the American Arbitration
Association as soon as practicable, and shall be, in any such case, a person who
is not affiliated with any party in interest to such arbitration and who has
substantial professional experience with regard to corporate legal matters.

          (b) The arbitrator shall consider the dispute at issue at Washington,
D.C. at a mutually agreed upon time and place within thirty (30) (or such longer
period as may be


                                       49
<PAGE>

acceptable to such Buyer Indemnitee(s) and the Seller) days of the designation
of the arbitrator.  The arbitration proceeding shall be held in accordance with
the Center for Public Resources Rules for Non-Administered Arbitration of
Business Disputes in effect on the date of the initial request by the relevant
Buyer Indemnitee or the Seller, as the case may be, that gave rise to the
dispute to be arbitrated (as such rules are modified by the terms of this
Agreement or may be further modified by mutual agreement of the relevant Buyer
Indemnitee(s) and the Seller) and shall include an opportunity for the parties
to conduct discovery in advance of the proceeding.  Notwithstanding the
foregoing, the relevant Buyer Indemnitee(s) and the Seller agree that they will
attempt, and they intend that they and the arbitrator should use their best
efforts in that attempt, to conclude the arbitration proceeding and have a final
decision from the arbitrator within ninety (90) days (or such longer period as
may be mutually acceptable to such Buyer Indemnitee(s) and the Seller) from the
date of selection of the arbitrator; provided, however, that the arbitrator
shall be entitled to extend such 90-day period one or more times to the extent
necessary for such arbitrator to place a dollar value on any claim that may be
unliquidated.  The arbitrator shall immediately deliver his or her written
decision with respect to the dispute to each of the parties, who shall promptly
act in accordance therewith.  Each Buyer Indemnitee and the Seller agree that
any decision of the arbitrator shall be final, conclusive and binding and that
they will not contest any action by any other party thereto in accordance with a
decision of the arbitrator.  It is specifically understood and agreed that any
party may enforce any award rendered pursuant to the arbitration provisions of
this Section 9.04 by bringing suit in any court of competent jurisdiction.

          (c) All fees, costs and expenses (including attorneys' fees and
expenses) incurred by the party that prevails in any such arbitration commenced
pursuant to this Section 9.04 or any judicial action or proceeding seeking to
enforce the agreement to arbitrate disputes as set forth in this Section 9.04 or
seeking to enforce any order or award of any arbitration commenced pursuant to
this Section 9.04 may be assessed against the party or parties that do not
prevail in such arbitration in such manner as the arbitrator or the court in
such judicial action, as the case may be, may determine to be appropriate under
the circumstances.  All costs and expenses attributable to the arbitrator shall
be allocated among the parties to the arbitration in such manner as the
arbitrator shall determine to be appropriate under the circumstances.

          9.05.  DEFENSE BY THE SELLER OF CLAIMS.  In connection with any claim
which may give rise to indemnity under this Article IX resulting from or arising
out of any claim or Proceeding against a Buyer Indemnitee by a Person that is
not a party hereto, the Seller may (unless such Buyer Indemnitee elects not to
seek indemnity hereunder for such claim), upon written notice to the relevant
Buyer Indemnitee, assume the defense of any such claim or Proceeding if the
Seller acknowledges to the relevant Buyer Indemnitee its right to indemnity
pursuant hereto in respect of the entirety of such claim (as such claim may have


                                       50
<PAGE>

been modified through written agreement of the parties or arbitration hereunder)
and provides assurances, reasonably satisfactory to such Buyer Indemnitee, that
the Seller will be financially able to satisfy such claim in full if such claim
or Proceeding is decided adversely.  If the Seller assume the defense of any
such claim or Proceeding, the Seller shall select counsel reasonably acceptable
to such Buyer Indemnitee to conduct the defense of such claim or Proceeding,
shall take all steps necessary in the defense or settlement thereof and shall at
all times diligently and promptly pursue the resolution thereof.  If the Seller
shall have assumed the defense of any claim or Proceeding in accordance with
this Section 9.05, the Seller shall be authorized to consent to a settlement of,
or the entry of any judgment arising from, any such claim or Proceeding, without
the prior written consent of such Buyer Indemnitee; provided, however, that the
Seller shall pay or cause to be paid all amounts arising out of such settlement
or judgment concurrently with the effectiveness thereof; provided, further, that
the Seller shall not be authorized to encumber any of the assets of any Buyer
Indemnitee or to agree to any restriction that would apply to any Buyer
Indemnitee or to its conduct of business; and provided, further, that a
condition to any such settlement shall be a complete release of such Buyer
Indemnitee with respect to such claim.  Such Buyer Indemnitee shall be entitled
to participate in (but not control) the defense of any such action, with its own
counsel and at its own expense.  Each Buyer Indemnitee shall, and shall cause
each of its Affiliates, officers, employees, consultants and agents to,
cooperate fully with the Seller in the defense of any claim or Proceeding being
defended by the Seller pursuant to this Section 9.05.  If the Seller does assume
the defense of any claim or Proceeding resulting therefrom in accordance with
the terms of this Section 9.05, such Buyer Indemnitee may defend against such
claim or Proceeding in such manner as it may deem appropriate, including
settling such claim or Proceeding after giving notice of the same to the Seller,
on such terms as such Buyer Indemnitee may deem reasonably appropriate.  If the
Seller seeks to question the manner in which such Buyer Indemnitee defended such
claim or Proceeding or the amount of or nature of any such settlement, the
Seller shall have the burden to prove by a preponderance of the evidence that
such Buyer Indemnitee did not defend such claim or Proceeding in a reasonably
prudent manner.

                      INDEMNIFICATION OF SELLER INDEMNITEES
                              FOLLOWING THE CLOSING

          10.01.  AGREEMENT TO INDEMNIFY.  If the Closing shall occur, the
Seller and each of the MK Affiliates (collectively, the "Seller Indemnitees")
shall be indemnified and held harmless to the extent set forth in this Article X
by the Buyer in respect of any and all Damages incurred by any Seller Indemnitee
as a result of each of the following:


                                       51
<PAGE>

          (a)  breach of any representation or warranty made by the Buyer in
this Agreement or in any exhibit or schedule of the Buyer hereto;
          (b) the breach or failure to perform by the Buyer after the Closing
Date of any of the covenants, agreements or obligations of the Buyer contained
in this Agreement or the Conveyance Documents, or in any exhibit or schedule,
hereto;
          (c)  any Buyer Obligations;
          (d)  any Environmental Liability of the Buyer or the Seller that
arises out of or results from the Business or any of the Purchased Assets from
and after the Closing Date, other than any Environmental Liability that arises
out of or results from the failure of the Seller to have obtained an approval,
authorization, certificate, consent, license, order, permit or other similar
authorization of any Governmental Authority or other Person required by any
Environmental Law;
          (e)  any Liability that arises out of or results from the Business or
any of the Purchased Assets from and after the Closing Date; and
          (f)  all actions, suits, proceedings, demands, assessments, judgments,
costs and expenses incident to the foregoing.

          10.02.    SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.  All
representations and warranties made by the Buyer in this Agreement or in any
exhibit or schedule hereto shall survive the Closing for a period of two years.
Notwithstanding any investigation or audit conducted before or after the Closing
Date or the decision of any party to complete the Closing, each party shall be
entitled to rely upon the representations and warranties set forth herein and
therein.  Any claim for indemnification pursuant to Section 10.01(a) made prior
to the end of the survival period shall continue to be subject to
indemnification in accordance with this Agreement.  All covenants of the Buyer
contained in this Agreement or in any exhibit or schedule hereto shall survive
the Closing.

          10.03.    CLAIMS FOR INDEMNIFICATION.  If any Seller Indemnitee shall
believe that such Seller Indemnitee is entitled to indemnification pursuant to
this Article X in respect of any Damages, such Seller Indemnitee shall give the
Buyer prompt written notice thereof.  Any such notice shall set forth in
reasonable detail and to the extent then known the basis for such claim for
indemnification.  The failure of such Seller Indemnitee to give notice of any
claim for indemnification promptly shall not adversely affect such Seller
Indemnitee's right to indemnity hereunder except to the extent that such failure
adversely affects the right of the Buyer to assert any reasonable defense to
such claim.  The Buyer shall have twenty (20) Business Days following its
receipt of such notice either (y) to acquiesce in such claim by giving such
Seller Indemnitee written notice of such acquiescence or (z) to object to the
claim by giving such Seller Indemnitee written notice of the objection.  If the
Buyer acquiesces in such claim or does not object thereto within such twenty
(20) Business Day period, such Seller Indemnitee shall be entitled to be
indemnified for all Damages incurred by such Seller Indemnitee in respect of
such claim.  If the Buyer timely objects to such claim


                                       52
<PAGE>

and such Seller Indemnitee and the Buyer are unable to resolve their dispute
within ten (10) Business Days following such objection (or such additional
period of time as may be mutually agreed to by such Seller Indemnitee and the
Buyer), the claim shall be submitted immediately to arbitration pursuant to
Section 10.04.

          10.04.    ARBITRATION OF DISPUTES RELATING TO INDEMNIFICATION.

          (a) Any dispute between any Seller Indemnitee and the Buyer under this
Article X shall be resolved by one arbitrator in accordance with the procedures
set forth in this Section 10.04.  Within ten (10) Business Days after expiration
of the ten (10) Business Day period referred to in Section l0.03, each of (y)
the relevant Seller Indemnitee(s) and (z) the Buyer shall designate a mutually
acceptable arbitrator who is, in any such case, not affiliated with any party in
interest to such arbitration and who has substantial professional experience
with regard to corporate legal matters.  If the Buyer and the relevant Seller
Indemnitee(s) fail to agree upon such arbitrator within such ten (10) Business
Day period, the arbitrator shall be appointed by the American Arbitration
Association as soon as practicable and shall be, in any such case, a person who
is not affiliated with any party in interest to such arbitration and who has
substantial professional experience with regard to corporate legal matters.

          (b)  The arbitrator shall consider the dispute at issue at a mutually
agreed upon time and place within thirty (30) (or such longer period as may be
acceptable to such Seller Indemnitee(s) and the Buyer) days of the designation
of the arbitrator.  The arbitration proceeding shall be held in accordance with
the Center for Public Resources Rules for Non-Administered Arbitration of
Business Disputes in effect on the date of the initial request by the relevant
Seller Indemnitee(s) or the Buyer, as the case may be, that gave rise to the
dispute to be arbitrated (as such rules are modified by the terms of this
Agreement or may be further modified by mutual agreement of the relevant Seller
Indemnitee(s) and the Buyer) and shall include an opportunity for the parties to
conduct discovery in advance of the proceeding.  Notwithstanding the foregoing,
the relevant Seller Indemnitee(s) and the Buyer agree that they will attempt,
and they intend that they and the arbitrator should use their best efforts in
that attempt, to conclude the arbitration proceeding and have a final decision
from the arbitrator within ninety (90) days (or such longer period as may be
mutually acceptable to such Seller Indemnitee(s) and the Buyer) from the date of
selection of the arbitrator; provided, however, that the arbitrator shall be
entitled to extend such 90-day period one or more times to the extent necessary
for such arbitrator to place a dollar value on any claim that may be
unliquidated.  The arbitrator shall immediately deliver his or her written
decision with respect to the dispute to each of the parties, who shall promptly
act in accordance therewith.  Each Seller Indemnitee and the Buyer agree that
any decision of the arbitrator shall be final, conclusive and binding and that
they will not contest any action by the other party in accordance with a
decision of the


                                       53
<PAGE>

arbitrator.  It is specifically understood and agreed that any party may enforce
any award rendered pursuant to the arbitration provisions of this Section 10.04
by bringing suit in any court of competent jurisdiction.

          (c) All fees, costs and expenses (including attorneys' fees and
expenses) incurred by the party that prevails in any such arbitration commenced
pursuant to this Section 10.04 or any judicial action or proceeding seeking to
enforce the agreement to arbitrate disputes as set forth in this Section 10.04
or seeking to enforce any order or award of any arbitration commenced pursuant
to this Section 10.04 may be assessed against the party or parties that do not
prevail in such arbitration in such manner as the arbitrator or the court in
such judicial action, as the case may be, may determine to be appropriate under
the circumstances.  All costs and expenses attributable to the arbitrator shall
be allocated among the parties to the arbitration in such manner as the
arbitrator shall determine to be appropriate under the circumstances.

          10.05.  DEFENSE BY THE BUYER OF CLAIMS.  In connection with any claim
which may give rise to indemnity under this Article X resulting from or arising
out of any claim or Proceeding against a Seller Indemnitee by a Person that is
not a party hereto, the Buyer may (unless such Seller Indemnitee elects not to
seek indemnity hereunder for such claim), upon written notice to the relevant
Seller Indemnitee, assume the defense of any such claim or Proceeding if the
Buyer acknowledges to the relevant Seller Indemnitee the right of such Seller
Indemnitee to indemnity pursuant hereto in respect of the entirety of such claim
(as such claim may have been modified through written agreement of the parties
or arbitration hereunder) and provides assurances, reasonably satisfactory to
such Seller Indemnitee, that the Buyer will be financially able to satisfy such
claim in full if such claim or Proceeding is decided adversely.  If the Buyer
assumes the defense of any such claim or Proceeding, the Buyer shall select
counsel reasonably acceptable to such Seller Indemnitee to conduct the defense
of such claim or Proceeding, shall take all steps necessary in the defense or
settlement thereof and shall at all times diligently and promptly pursue the
resolution thereof.  If the Buyer shall have assumed the defense of any claim or
Proceeding in accordance with this Section 10.05, the Buyer shall be authorized
to consent to a settlement of, or the entry of any judgment arising from, any
such claim or Proceeding, without the prior written consent of such Seller
Indemnitee; PROVIDED, HOWEVER, that the Buyer shall pay or cause to be paid all
amounts arising out of such settlement or judgment concurrently with the
effectiveness thereof; PROVIDED, FURTHER that the Buyer shall not be authorized
to encumber any of the assets of any Seller Indemnitee or to agree to any
restriction that would apply to any Seller Indemnitee or to its conduct of
business; PROVIDED, FURTHER that a condition to any such settlement shall be a
complete release of such Seller Indemnitee with respect to such claim.  Such
Seller Indemnitee shall be entitled to participate in (but not control) the
defense of any such action, with its own counsel and at its own expense.  Each
Seller Indemnitee shall, and shall cause each of his, her or its Affiliates,
officers, employees,


                                       54
<PAGE>

consultants and agents to, cooperate fully with the Buyer in the defense of any
claim or Proceeding being defended by the Buyer pursuant to this Section 10.05.
If the Buyer does not assume the defense of any such claim or Proceeding
resulting therefrom in accordance with the terms of this Section 10.05, such
Seller Indemnitee may defend against such claim or Proceeding in such manner as
such Seller Indemnitee may deem appropriate, including settling such claim or
Proceeding after giving notice of the same to the Buyer, on such terms as such
Seller Indemnitee may deem reasonably appropriate.  If the Buyer seeks to
question the manner in which such Seller Indemnitee defended such claim or
Proceeding or the amount of or nature of any such settlement, the Buyer shall
have the burden to prove by a preponderance of the evidence that such Seller
Indemnitee did not defend such claim or Proceeding in a reasonably prudent
manner.

          10.06.  POST-CLOSING OBLIGATIONS.  Notwithstanding anything in this
Agreement to the contrary, it is expressly agreed that none of the Sureties or
the Banks have any obligations or liabilities under this Agreement.

reference only and shall be ignored in the construction or interpretation
hereof.  All references to an Article or Section include all subparts thereof.

          12.10.  SEVERABILITY.  If any provision of this Agreement, or the
application thereof to any Person, place or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other Persons,
places and circumstances shall remain in full force and effect only if, after

provide for the consummation of the transactions contemplated hereby in
substantially the same manner as originally set forth at the later of the date
this Agreement was executed or last amended.

          (a) Whenever required by the context, any gender shall include any
other gender, the singular shall include the plural and the plural shall include
the singular.  The words "herein," "hereof," "hereunder," and words of similar
import refer to the Agreement as a whole and not to a particular section.
Whenever the word "including" is used in this Agreement, it shall be deemed to
mean "including, without limitation," "including, but not limited to" or other
words of similar import such that the items following the word "including" shall
be deemed to be a list by way of illustration only and shall not be deemed to be
an exhaustive list of applicable items in the context thereof.  All references
in this Agreement to Seller shall include the predecessor thereof.

          (b) The parties hereto intend that each representation, warranty, and
covenant contained herein shall have independent significance.  If any party has
breached any representation, warranty or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant
relating to the same subject matter (regardless of the relative levels of
specificity) which the party has not breached shall not detract from or mitigate
the fact that the party is in breach of the first representation, warranty or
covenant.

          12.12.  CUMULATIVE REMEDIES.  Except as expressly provided in Section
11.02 hereof, the rights, remedies, powers and privileges herein provided are

                            STOCK PURCHASE AGREEMENT

     This Stock Purchase Agreement ("Agreement") is made and entered into as of
the 21st day of September, 1995, by and between Morrison Knudsen Corporation, a
Delaware corporation ("Morrison Knudsen"), and Morrison Knudsen Corporation, an
Ohio corporation ("MKC") (Morrison Knudsen and MKC being referred to
individually as a "Seller" and collectively as the "Sellers"), and Tutor-Saliba
Corporation, a California corporation (the "Purchaser").

                               W I T N E S E T H:

     WHEREAS, Morrison Knudsen is the owner of all the issued and outstanding
shares of capital stock of MKC; MKC is the owner of all the issued and

("Black Micro") (MKI, MKP, Murphy, E.E. Black, Black Construction and Black

referred to as the "Companies"); and

     WHEREAS, the Purchaser desires to acquire the shares of issued and
outstanding capital stock of each of the Companies as contemplated herein by
acquiring all the issued and outstanding shares of capital stock of MKI (the
"MKI Shares"), and the Sellers have agreed to sell the MKI Shares to the
Purchaser on the terms and subject to the conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the premises and the respective
representations, warranties, covenants, agreements and conditions contained
herein, the parties hereto agree as follows:

<PAGE>

                                    ARTICLE I

                                PURCHASE AND SALE

     1.1  TRANSFER OF SHARES.  Pursuant to the terms of this Agreement, on the
Effective Date (as hereinafter defined), MKC will sell, transfer, convey and
assign the MKI Shares and deliver to the Purchaser certificates representing the
MKI Shares, together with stock powers duly endorsed by MKC so that the MKI
Shares may be duly registered in the Purchaser's name.

     1.2  CONSIDERATION.  On the terms and subject to the conditions of this
Agreement, on the Effective Date, the Purchaser will purchase the MKI Shares in
exchange for $17,100,000.00 in cash ("Purchase Price").

     1.3  CONTEMPLATED TRANSFER OF RETAINED ASSETS AND RELATED MATTERS.  (a)
Prior to the Closing (as defined below), the Sellers shall cause (i) each of
MKI, MKP and E.E. Black (collectively, the "Designated Companies") to transfer
to MKC, by dividend or otherwise, the assets of each of the Designated Companies
(the "Retained Assets"), except for the assets listed on Schedule 1.3A which
shall include all small tools, office furniture, fixtures and equipment and any
other items categorized as minor equipment in the books and records of the
Designated Companies (except for mutually acceptable exclusions), and (ii) MKC
to assume all the liabilities, commitments and other obligations of each of the
Designated Companies of every type and description whether recorded or not
("Retained Liabilities), except for the intercompany accounts payable by any
Company to any other Company, MKC or Morrison Knudsen and the liabilities listed
on Schedule 1.3B.  In addition, prior to the Closing, MKC shall transfer to its
payroll all employees of the Designated Companies.

          (b)  Prior to the Closing, the Sellers shall secure and deliver to the
Purchaser the written agreement of the Fidelity and Deposit Company of Maryland
("F&D") to release the Purchaser and E.E. Black from all liabilities arising out
of, or in any way relating to any performance, payment or material bond issued
by F&D prior to the Effective Date with respect to any E.E. Black project
(individually an "E.E. Black Project Bond" and collectively the "E.E. Black
Project Bonds").

          (c)  As promptly as practicable after the date of this Agreement, the
Seller shall secure and deliver to the Purchaser (i) written evidence of the
release of each of the Designated Companies from the obligation to pay, perform
or discharge each of the Retained Liabilities from the owner, lessor, joint
venture partner, bonding company, surety, or other entity or person entitled to
the benefits thereof, as the case


                                       -2-
<PAGE>

may be, and (ii) written evidence that each E.E. Black Project Bond has been
cancelled and substituted with a new performance, payment or material bond, as
the case may be, that does not guarantee the performance by E.E. Black of any
obligations covered thereby.

          (d)  The Sellers desire to retain the sole authority to direct the
defense of the matters described on Schedule 1.3D (the "Schedule 1.3D Items")
involving Murphy, Black Construction and Black Micro (an "Additional Designated
Company" or the "Additional Designated Companies").  Accordingly, for the
limited purpose of clause (e) of this Section 1.3 and for the limited purpose of
resolving the Schedule 1.3D Items, the Schedule 1.3D Items shall be deemed to be
Retained Liabilities.  If requested by the Sellers after the Closing, the
Purchaser shall cause the officers and employees of the Additional Designated
Companies to cooperate with the Sellers in connection with the resolution of the
Schedule 1.3D Items, including, without limitation, providing reasonable access
to books and records of the Additional Designated Companies relating to the
Schedule 1.3D Items.

          (e)  The Sellers, jointly and severally, agree to protect, indemnify,
defend and hold harmless the Purchaser, E.E. Black and the Additional Designated
Companies from all damages (including, exemplary damages and penalties), losses,
deficiencies, costs, expenses, obligations, fines, expenditures, claims and
liabilities, including reasonable counsel fees and reasonable expenses of
investigating, defending and prosecuting litigation (collectively, the
"Damages"), suffered by E.E. Black, any Additional Designated Company or the
Purchaser as a result of, caused by, arising out of, or in any way relating to
any of the Retained Liabilities (including, without limitation, the E.E. Black
Project Bonds and the Schedule 1.3D Items).  Notwithstanding any provision in
this Agreement to the contrary, the foregoing indemnity agreement shall neither
be subject to any time limit nor any limit on the amount of Damages recoverable
by E.E. Black, any Additional Designated Company or the Purchaser thereunder.

          (f)  For the purposes of this Agreement, the performance by the
Sellers of their obligations under this Section 1.3 shall not be considered a
material adverse change in the financial condition or results of operations of
E.E. Black, the Additional Designated Companies with respect to the Schedule
1.3D Items only, or the combined operations of the Companies, and none of the
representations, warranties or covenants of the Sellers set forth in this
Agreement shall relate to the Retained Assets and/or the Retained Liabilities.
Furthermore, neither the Retained Assets nor the Retained Liabilities need be
disclosed on any other schedule required to be delivered by the Sellers to the
Purchaser pursuant to this Agreement.

     1.4  ELIMINATION OF INTERCOMPANY ACCOUNTS.  Immediately prior to the
Closing, the Sellers shall contribute all long-term debt payable by any Company
to the Sellers or any affiliate thereof and all other accounts payable by any
Company to the Sellers or any affiliate thereof to the capital of the
appropriate Company as additional paid in capital, and all other intercompany
accounts between the Sellers or any affiliate thereof on the one hand and any
Company on the other hand, shall be eliminated by contribution to capital or
dividend.

                                   ARTICLE II

                                     CLOSING

     2.1  CLOSING.  Subject to the satisfaction of the conditions to closing set
forth in Article VI, the closing (the "Closing") of the acquisition of the MKI
Shares shall be held at the offices of Morrison Knudsen at Morrison Knudsen
Plaza, Boise, Idaho, 83712 commencing at 9:00 a.m., Boise, Idaho time, on the
earlier of September 22, 1995 or the first business day following the
satisfaction of the conditions set forth in Article VI, provided that the
parties may select such other place, date and time as may be mutually agreed
upon by them.  The "Effective Date," as referred to herein, shall mean the date

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE SELLERS

     The Sellers, jointly and severally, hereby represent and warrant to the
Purchaser that as of (a) the date hereof (except in the case of any
representation and warranty that is expressly made subject to a schedule listed
in Schedule 6.1(q) hereof in which event such representation and warranty shall
be deemed to be made only as of the time the Purchaser accepts such schedule
pursuant to Section 6.1(q) hereof) and (b) as of the Effective Date:

     3.1  ORGANIZATION AND EXISTENCE.  Each Company is duly incorporated,
validly existing and in good standing  under the laws of the jurisdiction
indicated in Schedule 3.1.  Each Company has full corporate power and authority
to own and hold the properties and assets it now owns and holds and to carry on
its businesses as and where such properties are now owned or held and such
business is now conducted.  Each Company is duly licensed or qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
in which the character of the properties and assets now owned or held by it or
the nature of the business now conducted by it requires it


                                       -4-
<PAGE>

to be so licensed or qualified and where the failure so to qualify would not
reasonably be expected to affect materially and adversely the business,
operations, affairs, properties, assets or condition (financial or otherwise) of
such Company.  Schedule 3.1 contains a list of each jurisdiction in which each
Company is duly licensed or qualified to do business as a foreign corporation.
Except as disclosed in Schedule 3.1, no Company has any direct or indirect
investment or interest in or control over any other corporation, partnership,
joint venture or other business entity other than another Company.

     3.2  CAPITALIZATION.  (a) The entire authorized capital stock of each
Company consists of the class or classes of capital stock listed in Schedule
3.2.  Schedule 3.2 also sets forth the number of shares of each class of
authorized capital stock of each Company that is issued and outstanding.  All
issued and outstanding shares of capital stock of each Company are fully paid
and nonassessable.  The outstanding shares of capital stock of each Company are
owned beneficially and of record by the party indicated in Schedule 3.2, free
and clear of all liens, security interests, claims, charges, encumbrances,
rights, options to purchase, voting trusts or other voting agreements and calls
and commitments of every kind (collectively, the "Stock Encumbrances").

          (b)  There are no outstanding subscriptions, options, convertible
securities, warrants, calls or rights of any kind (issued or granted by, or
binding upon, the Sellers or any Company) to purchase or otherwise acquire any
security of or equity interest in any Company.  Except as set forth in Schedule
3.2, MKC has full legal right to sell, assign and transfer the MKI Shares to the
Purchaser and will, upon delivery of the MKI Shares to the Purchaser pursuant to
the terms hereof, transfer to the Purchaser good and valid title to the MKI
Shares, free and clear of all Stock Encumbrances.

     3.3  AUTHORITY AND APPROVAL.  Each Seller has the corporate power and
authority to execute and deliver this Agreement and the other agreements and
documents contemplated to be delivered by it pursuant to Article VI hereof
("Seller Related Documents"), to consummate the transactions contemplated hereby
and thereby and to perform all the terms and conditions hereof and thereof to be
performed by it.  The execution and delivery by each Seller of this Agreement
and the Seller Related Documents, the performance by each Seller of all the
terms and conditions hereof and thereof to be performed by it and the
consummation of the transactions contemplated hereby and thereby have been duly
authorized and approved by the Board of Directors of each Seller and no approval
of the stockholders of either Seller is required in connection with the
consummation of the transactions contemplated hereby and thereby.  This
Agreement constitutes and, upon execution and delivery, the Seller Related
Documents will constitute the valid and binding obligation of each Seller
enforceable in


                                       -5-
<PAGE>

accordance with their respective terms, except as such enforcement may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting enforcement of creditors' rights generally and by general
principles of equity (whether applied in a proceeding at law or in equity).

     3.4  NO CONFLICT.  Except as set forth in Schedule 3.4, this Agreement and
the Seller Related Documents and the execution and delivery hereof and thereof
by each Seller do not and will not, and the fulfillment and compliance with the
terms and conditions hereof and thereof and the consummation of the transactions
contemplated hereby and thereby will not, (a) conflict with any of, or require
the consent of any person or entity under, the terms, conditions or provisions
of the charter documents or bylaws or equivalent governing instruments of either
Seller or any Company, (b) violate any provision of, or require any consent,
authorization or approval under, any law or administrative regulation or any
judicial, administrative or arbitration order, award, judgment, writ, injunction
or decree applicable to either Seller that has not already been obtained under

as set forth in Schedule 3.4, conflict with, result in a breach of, constitute a
default under (whether with notice or the lapse of time or both), or accelerate
or permit the acceleration of the performance required by, or require any
consent, authorization or approval under, any indenture, mortgage or lien, or
any agreement, contract, commitment or instrument to which either Seller or any
Company is a party or by which any of them is bound or to which any property of
either Seller or any Company is subject, or (d) result in the creation of any
Encumbrances (as defined below) on the assets of any Company under any such
indenture, mortgage, lien, lease, agreement or instrument.

     3.5  LAWS AND REGULATIONS; LITIGATION.  Except as set forth in Schedule 3.5
and except for those violations which would not reasonably be expected
materially and adversely to affect the businesses, operations, affairs,
properties, assets or condition (financial or otherwise) of a particular
Company, no Company is in violation of or in default under any law or
regulation, or under any order of any court or foreign, federal, state,
municipal, territorial or other governmental department, commission, board,
bureau, agency or instrumentality applicable to it; and, except to the extent
set forth in Schedule 3.9 and except for those claims, fines, actions, suits,
demands, investigations or proceedings which would not reasonably be expected
materially and adversely to affect the business, operations, affairs,
properties, assets or condition (financial or otherwise) of a particular
Company, there are no claims, fines, actions, suits, demands, investigations or
proceedings pending or, to the best knowledge of the Sellers, threatened against
or affecting any Company, at law or in equity, or before or by any foreign,
federal, state, municipal, territorial or other governmental department,


                                       -6-
<PAGE>

commission, board, bureau, agency or instrumentality having jurisdiction over
any Company.  Except as set forth in Schedule 3.9 or Schedule 3.12 and except
for such lack of compliance, violations or liabilities that would not reasonably
be expected materially and adversely to affect the businesses, operations,
affairs, properties, assets, or condition (financial or otherwise) of a
particular Company, each Company is in material compliance with all applicable
foreign, federal, state, territorial and local statutes, ordinances, permits,
permit applications, licenses, orders, approvals, variances, rules and
regulations expressly applicable to it.

     3.6  NO DEFAULT.  Except as set forth in Schedule 3.6, no Company is in
default under, and no condition exists that with notice or lapse of time or both
would constitute a default under, (a) any mortgage, loan agreement, indenture,
evidence of indebtedness or other instrument evidencing borrowed money to which
it or any of its properties is bound, (b) any judgment, order or injunction of
any court, arbitrator or governmental agency, or (c) any construction contract,
surety agreement or other agreement, except for such defaults and conditions
that, individually and in the aggregate, would not reasonably be expected
materially and adversely to affect the business, operations, affairs,
properties, assets or condition (financial or otherwise) of such Company.

     3.7  FINANCIAL STATEMENTS.  Attached as Schedule 3.7 is a copy of the
unaudited consolidating balance sheet of the Companies (the "Balance Sheet") as
at April 30, 1995 (the "Balance Sheet Date").

     3.8  NO ADVERSE CHANGES.  Except as disclosed in Schedule 3.8 and except on
account of matters that generally affect the economy or the industry in which
each Company is engaged, since the Balance Sheet Date there have been no
material adverse changes in (a) the financial condition of any Company from that
set forth in the Balance Sheet or (b) the business, operations, affairs,
properties, assets or condition (financial or otherwise) of any Company, in each
case other than changes in the ordinary course of business, consistent with past
practices.  Except as disclosed in Schedule 3.8, since the Balance Sheet Date no
Company has declared, set aside or paid any dividends, or made any
distributions, in respect of its equity securities, or repurchased, redeemed or
otherwise acquired any such securities or transferred any cash to the Sellers
except in payment for services actually rendered to or in reimbursement for
expenses actually paid on behalf of such Company.

     3.9  LIABILITIES.  Except as set forth in Schedule 3.9 or as otherwise set
forth in the Balance Sheet, no Company has any obligation or liability material
to that Company (whether accrued, absolute, contingent, unliquidated or
otherwise, whether


                                       -7-
<PAGE>

due or to become due), other than contractual liabilities incurred in the
ordinary course of business which are not required to be disclosed in the
Balance Sheet and other than liabilities which have arisen after the Balance
Sheet Date in the ordinary course of business, consistent with past practices.

     3.10 TAXES.  Except as otherwise expressly noted in this Section 3.10 or
set forth in Schedule 3.10:  The operations of the Companies have been reflected
in the consolidated federal income tax returns of the affiliated group of
corporations having Morrison Knudsen as its common parent (the "Seller Group")
that have been filed or will be timely filed pursuant to the Internal Revenue
Code of 1986, as amended (the "Code"), for the taxable years ended on or before
December 31, 1994 during which Morrison Knudsen owned, directly or indirectly,
100% of the capital stock of any Company.  Black Construction and Black Micro
are not included in the Seller Group but have filed separate tax returns in Guam
and the Commonwealth of the Northern Mariana Islands as the circumstances
require.  Each Company and Morrison Knudsen have (or will have by the Closing)
caused to be duly filed in a timely manner (taking into account all extensions
of due dates) with the appropriate foreign, federal, state, local, territorial
and other governmental authorities all material returns, information returns or
statements, and reports with respect to Taxes (as defined in subsection (a) of
Section 7.1 hereof) which are required to be filed by or with respect to each
Company or with respect to any member of the Seller Group, to the extent any
Company could be liable for such Taxes, and have (or will have by the Closing)
caused to be paid or deposited or made adequate provision in accordance with
generally accepted accounting principles consistently applied for the payment of
all Taxes (including estimated Taxes) required with respect to the periods
covered by such returns, statements or reports or by any taxing authority.
Adequate provision has been made for all Taxes due with respect to each Company
and with respect to each member of the Seller Group, to the extent any Company
could be liable for such Taxes, for all periods through the Balance Sheet Date,
and adequate provision will be made for all such Taxes for the period between
the Balance Sheet Date and the Effective Date.  Except as set forth in Schedule
3.10 and except for tax liens securing the payment of Taxes not yet due and
payable, (a) there are no tax liens upon any assets of any Company, (b) there
are no outstanding agreements or waivers by or with respect to any Company or
any member of the Seller Group extending the period for assessment or collection
of any Taxes for which any Company could be liable, (c) there is no pending
action, proceeding or investigation, and, to the best knowledge of the Sellers,
no action, proceeding or investigation has been threatened by any governmental
authority, for assessment or collection of Taxes with respect to any Company or
Taxes of any member of the Seller Group for which any Company could be held
liable, and (d) no claim for assessment or collection of Taxes has been asserted
and no actual or proposed assessment has been made against the


                                       -8-
<PAGE>

Sellers or any Company with respect to the Taxes of any Company or Taxes of any
member of the Seller Group for which any Company could be held liable.  No
consent or election under Section 341(f) of the Code has been filed by or for
any Company.

     3.11 RECEIVABLES.  Schedule 3.11 sets forth a list, as of the Balance Sheet
Date, of the accounts receivable (in the form of an aged account balance) and
notes receivable of each Company.  Except to the extent of the reserve for bad
debts reflected on Schedule 3.11, such accounts and notes are collectible in the
amounts shown in Schedule 3.11.  With respect to all accounts receivable and
notes receivable that have been created by each Company subsequent to the
Balance Sheet Date there is no pending contest to the amount or validity thereof
and, to the best knowledge of the Sellers, no reasonable basis exists for any
such contest.

     3.12 INTELLECTUAL PROPERTY.  All patents, trademarks, trade names, brand
names and copyrights (in each case, whether issued or pending), and all licenses
or rights in favor of each Company with respect to any of the foregoing, owned
or possessed by each Company (collectively, the "Intellectual Property

report, if any, for each employee pension benefit plan and Internal Revenue
Service Forms 5500 for each Company Plan for which a Form 5500 has been required
since August 14, 1992.  All financial statements and actuarial reports have been
prepared in accordance with generally accepted accounting principles and
actuarial principles, applied on a uniform and consistent basis.

          (b)  Schedule 3.19 identifies each of the Company Plans which purports

A copy of each Qualified Plan and the most recent determination by the Internal
Revenue Service with respect to each of the Qualified Plans has been delivered
to the Purchaser.  All of such determination letters remain in effect and have
not been revoked.  Except as listed on Schedule 3.19, no Qualified Plan has been
amended since the issuance of the most recent determination letter.  Except as
listed on Schedule 3.19, no issue concerning qualification of any Qualified Plan
is pending before or, to the best knowledge of the Sellers, threatened by the
Internal Revenue Service.  In all materials respects each Qualified Plan has
been administered according to its terms, except for those terms which are
inconsistent with the changes required by the Code and any regulations and
rulings promulgated thereunder for which changes are not yet required to be
made, in which case each Qualified Plan has been administered in accordance with
the provisions of the Code and such regulations and rulings, and no Company or
any fiduciary of any Qualified Plan has done anything which would adversely
affect the qualified status of any Qualified Plan or any related trust.

          (c)  Except as listed in Schedule 3.19, each Company is in material
compliance with the requirements prescribed by any and all statutes, orders,
governmental rules, and regulations applicable to the Company Plans and all
material reports and disclosures relating to the Company Plans required to be

Plan has occurred, nor has a notice of intent to terminate any existing
Qualified Plan been issued by a Company.  The Pension Benefit Guaranty
Corporation (the "PBGC") has not instituted, and, to the best knowledge of the
Sellers, is not expected to institute, any proceedings to terminate any Company
Plan.

          (e)  No Qualified Plan has suffered any "accumulated funding
deficiency" within the meaning of ERISA Section 302 and Section 412 of the Code
(which remains outstanding on the Effective Date), whether or not waived, and if
any Qualified Plan were terminated on the Effective Date, no Company would have
any material liability to any participants or beneficiaries as a result of the
termination except to the extent of funds set aside for such purpose or
reflected as reserved for such purpose in the Balance Sheet.  Except as listed
in Schedule 3.19, each Company has made full and timely payment of, or has
accrued pending full and timely payment, all amounts which are required under
the terms of each Qualified Plan and in accordance with applicable laws to be
paid as a contribution to each Qualified Plan.  Schedule 3.19 sets forth the

Multiemployer Plan within the meaning of the Multiemployer Pension Plan
Amendments Act of 1980.

          (h)  No Company has any material liability to the PBGC.  Except as
listed in Schedule 3.19, with respect to any Qualified Plan or any Company, no
termination liability to the PBGC or material withdrawal liability to any
Multiemployer Plan has been or is expected to be incurred or would be incurred
if any Qualified Plan were terminated on the Effective Date or if any Company
were to withdraw from any Multiemployer Plan on the Effective Date.  Except as
listed in Schedule 3.19, since August 14, 1992, there has been no "reportable
event," as defined in Section 4043(b) or 4043(c) of ERISA, with respect to any
Qualified Plan that is subject to Title IV of ERISA, for which notice has not
been waived.

          (i)  No Company is liable or has been advised that it is liable for
any funding taxes under Code Sections 413(b)(6) or 4971 on account of an
accumulated funding deficiency of any Multiemployer Plan to which any Company
has contributed or is required to contribute.

          (j)  No Company has made or is obligated to make any nondeductible

rate of compensation payable or to become payable to any of its officers,
directors, employees, consultants or agents, or make any commitment or incur any
liability to any labor union (not currently set forth in the collective
bargaining agreement), or pay or agree to pay any bonuses or severance pay other
than in accordance with currently established policies or agreements.

          (m)  The transaction contemplated by this Agreement along with any
amounts paid or payable by any Company or any member of the Controlled Group (as
defined in paragraph (x) below) has not resulted in and will not result in
payments to "disqualified individuals" (as defined in Section 280G(c) of the
Code) of any Company which, individually or in the aggregate, will constitute
"excess parachute payments" (as defined in Section 280G(b) of the Code)
resulting in the imposition of the excise tax under Section 4999 of the Code or
the disallowance of deductions under Section 280G of the Code.

          (n)  Except as listed in Schedule 3.15, no Company (i) is a party to
any collective bargaining agreement; (ii) is obligated to bargain with any other
labor organization, (iii) knows of any charges or threatened charges of unfair
labor practices, or (iv) has failed to materially comply with all applicable,
foreign, federal, territorial, state and local regulations respecting employment
and employment practices.

          (o)  Except as set forth in Schedule 3.19, no Company is liable for

assessments or forfeitures arising from any employment matter.

          (p)  No Company has committed any material violations of the Civil
Rights Act of 1964, as amended, the federal wage and hour laws, federal or state
income, unemployment or social security withholding laws or any laws of a
similar or comparable nature in Guam, the Federated States of Micronesia, the
Commonwealth of the Northern Mariana Islands, Palau and the Philippines.

          (q)  Each Company has complied in all material respects with
applicable workers compensation statutes.

          (r)  No Company or any other "disqualified person" or "party in
interest," as defined in Section 4975 of the Code and ERISA Section 3(14),
respectively,


                                      -15-
<PAGE>

has engaged in any "prohibited transaction," as defined in Section 4975 of the
Code or ERISA Section 406 with respect to the Company Plans for which an
exemption does not exist, and all "fiduciaries," as defined in Section 3(21) of
ERISA, with respect to the Company Plans have complied in all material respects
with the requirements of Section 404(a) or (b) of ERISA.  Neither any Company
nor any party in interest or disqualified person with respect to the Company
Plans has taken or omitted to take any action with respect to the Company Plans
which could lead to the imposition of a material excise tax under the Code or a
material fine under ERISA.

          (s)  Other than routine claims for benefits, there are no actions,
audits, investigations, suits, or claims pending, or, to the best knowledge of
the Sellers, threatened (collectively, the "Actions") against any of the Company
Plans or any fiduciary of any of the Company Plans (but such representation is
limited to Actions with respect to any fiduciary while acting on behalf of the
Company Plans) or against the assets of any of the Company Plans.

          (t)  Except as listed in Schedule 3.19, as of the Effective Date, the
consummation of the transactions contemplated hereby will not accelerate or
increase any liability under any Company Plan because of an acceleration or
increase of any of the rights or benefits to which employees may be entitled
thereunder.

          (u)  Unless otherwise expressly permitted or required by the terms of
this Agreement, from the date hereof until the Effective Date, no Company shall
amend any Company Plans, except to the extent necessary to maintain compliance
with the Code or ERISA or to obtain a favorable determination letter from the
IRS for any Qualified Plan, increase any benefits or rights under any Company
Plan, or adopt any new plan, program, policy, or arrangement which, if it
existed as of the Effective Date, would constitute a Company Plan.

          (v)  Except as listed in Schedule 3.19, or as required by law, no
Company has any obligation to any retired or former employee, or any current
employee upon retirement, under any Company Plan.  As of the Effective Date,
except for professional fees, any applicable IRS user or filing fees and any
obligations arising under applicable laws of the Territory of Guam and
surrounding islands, any Company Plan can be terminated without resulting in
additional penalties, premiums, fees, or similar charges to the sponsoring
Company or to the Purchaser.  To the extent such obligations exist, such
obligations are fully funded or adequately reserved for by each Company or
represent Retained Liabilities to be retained by the Sellers.

Section 414 of the Code ("Controlled Group"), sponsors or maintains any employee

Company, any Company Plan, the fiduciaries thereof, or their respective plan
assets, to any material taxes, liens, encumbrances, penalties, or any other
material liabilities.

          (y)  Neither the Company nor any member of its Controlled Group is a

     5.3  ACCESS.  Upon specific request made to either James S. Voorhees of MKC
or Jonathan M. Robertson of Morrison Knudsen, the Sellers will afford to the
Purchaser and its authorized representatives reasonable access to each Company's
financial, title, tax, corporate and legal materials and operating data and
information available as of the date hereof and which becomes available to the
Sellers at any time prior to the Effective Date, and will furnish to the
Purchaser such other information as it may reasonably request, unless any such
access and disclosure would violate the terms of any agreement to which either
Seller or any Company is bound or any applicable law or regulation.  The Sellers
will use their reasonable business efforts to secure all requisite consents for
the examination by the Purchaser and its representatives of all information
covered by confidentiality agreements.  The Sellers will cause each Company to
allow the Purchaser access to and consultation with the lawyers, accountants,
and other professionals employed by or used by such Company for the purposes of
negotiating, preparing, executing and performing this Agreement.  Any such
consultation shall occur under circumstances appropriate to maintain intact the
attorney-client privilege as to privileged communications and attorney work
product.  Additionally, the Sellers will afford to the


                                      -25-
<PAGE>

Purchaser and its authorized representatives reasonable access to the books and
records of the Sellers insofar as they relate to property, accounting and tax
matters of any Company.  Until the Effective Date, the confidentiality of any
data or information so acquired shall be maintained by the Purchaser and its
representatives, except in those cases where, on the advice of counsel,
disclosure is required in governmental filings or judicial, administrative or
arbitration proceedings.  Further, the Sellers will afford to the Purchaser and
its authorized representatives reasonable access from the date hereof until the
Effective Date, during normal business hours, to each Company's assets and
properties; provided that such access shall be at the sole cost, expense and
risk of the Purchaser.  The Sellers acknowledge that the Purchaser has had
access and will continue to have access to the senior management of each Company
and that each of such members of senior management is entitled to reveal to the
Purchaser and its representatives information concerning any Company that may be
deemed confidential and proprietary.

     5.4  ANTITRUST NOTIFICATION; OTHER REPORTING REQUIREMENTS.  The Sellers and
the Purchaser previously filed with the Federal Trade Commission and the

waiting period provided for thereunder.  The Sellers shall cause each Company

foreign, federal, state, territorial, local and other governmental authorities

     5.7  ADDITIONAL DISCLOSURES AND INFORMATION.  The Sellers shall give the
Purchaser prompt notice if at any time on or prior to the Effective Date there
is a change in any state of facts, or there is the occurrence, nonoccurrence or
existence of any event subsequent to the date of this Agreement, which change or
event is known to any executive officer of either Seller and which would make
any representation and warranty (including the information set forth in the
schedules) made by the Sellers to the Purchaser not true or correct in any
material respect, it being the intention of the parties to this Agreement that
the Sellers shall engage in a continuous disclosure process from the date of
this Agreement through the Effective Date.

     5.8  DISCLOSURE OF BREACH.  The Purchaser covenants and agrees that if, in
the course of its investigation of the businesses of the Companies, anything
comes to its attention that indicates there has been or there is or there could

agreements contained in this Agreement, Purchaser will promptly notify the
Sellers of such matter and will give the Sellers a reasonable opportunity to
cure or correct any such breach.

     5.9  NOTICE OF FAILURE OF CONDITION.  Each party hereto will as promptly as
reasonably practicable notify each other party in writing of the occurrence of
any event of which it obtains knowledge which will result in the failure to
satisfy the conditions specified in Section 6.1 hereof, in the case of events
relating to the Sellers, and Section 6.2 hereof, in the case of events relating
to the Purchaser.

     5.10 INTERFERENCE WITH RELATIONSHIPS.  From the date hereof until the
Effective Date, the Purchaser will not take any action or engage in any practice
calculated or designed to impair the relationships of the Companies with their
customers, suppliers or others having business dealings with any of them.

to comply with applicable requirements of Environmental Law concerning the
transfer of the MKI Shares, including without limitation the filing with
appropriate permitting agencies of any notices required in reference to the
change in ownership for the purpose of effecting the transfer or issuance of the
permits required under Environmental Law for the operation and the conduct of
the business of any Company.  The Sellers shall assist the Purchaser in
effectuating the issuance or transfer, as promptly as is reasonably possible, of
all Environmental Permits required as of the Effective Date.  The Sellers shall
notify the Purchaser of any notices or reports required from the Purchaser in
connection with the transfer or issuance of the required Environmental Permits,
and the Purchaser shall cooperate in providing promptly such notices or reports.

occupy the space, MKC shall permit the Purchaser (a) to store the office
furniture and equipment owned by E.E. Black on the Effective Date at MKC's
leased premises in Honolulu and (b) to store construction equipment as space
permits at MKC's Campbell Yard, in each case without a requirement for the
payment of rent by the Purchaser.

     5.13 FURTHER ASSURANCES.  Each of the Purchaser and the Sellers agrees that
it will execute and deliver, and cause to be executed and delivered, on and
after the Effective Date, all such instruments and will take all reasonable
actions as may be necessary to transfer the MKI shares to the Purchaser, on the
terms contained herein, and otherwise secure the benefits of this Agreement to
the Purchaser and the Sellers in accordance with the terms hereof.  The Sellers
also agree, to the extent practicable under the circumstances, to cooperate with
the Purchaser after the Closing by permitting any resident management employee
or other designated person named in any contractor license of a Company in
Hawaii or elsewhere (an "RME") who is no longer an employee of such Company
after the Effective Date to continue to serve as the RME under such contractor's
license until the Purchaser can secure the substitution of another RME (which
the Purchaser undertakes to do promptly), all to the end that each Company can
continue to maintain its contractor licenses after the Closing without
interruption.

                    properties and assets now owned or held by it or the nature
                    of business now conducted by it requires it to be so

                    affecting the enforcement of creditors' rights generally,
                    and except that such counsel need not express an opinion as
                    to whether any covenant contained in this Agreement or any
                    Seller Related Document is specifically enforceable);

with each other, in the negotiation and settlement of any proceeding described
in this Section 7.3.  The Purchaser will provide, or cause to be provided, to
the Sellers necessary authorizations, including powers of attorney, to control
any proceedings which the Sellers are entitled to control pursuant to this
Section 7.3.

     7.4  PAYMENT OF TAXES.  All Taxes with respect to any Company shall be paid
by the party that is legally responsible therefor.  Except as otherwise provided
in this Article VII, any amount to which a party is entitled under this Article
VII shall be promptly paid to such party by the party obligated to make such
payment following written notice to the party so obligated stating that the
Taxes to which such amount relates have been paid or incurred and providing
details supporting the calculation of such amount.

     7.5  COOPERATION AND EXCHANGE OF INFORMATION.  The Purchaser on the one
hand, and the Sellers on the other hand, will provide, or cause to be provided,
to the other party copies of all correspondence received from any taxing
authority by such party or any of its affiliates in connection with the
liability of any for Taxes for any period for which such other party is or may
be liable under subsection (b) or (c) of Section 7.1 hereof.  The Sellers shall
assist the Purchaser in obtaining the consent of the partners in any tax
partnership in which any Company owns an interest to make (i) any elections in a
return of the tax partnership which the Purchaser deems necessary and (ii) an
allocation of tax partnership items in the manner described in subsection (d) of
Section 7.1 hereof.  The parties will provide each other with such cooperation
and information as they may reasonably request of each other in preparing or
filing any return, amended return, or claim for refund, in determining a
liability or a right of refund, or in conducting any audit or other proceeding,
in respect of Taxes imposed on the parties or their respective affiliates.  The
Purchaser on the one hand, and the Sellers


                                      -40-
<PAGE>

on the other hand, and their affiliates will preserve and retain all returns,
schedules, work papers and all material records or other documents relating to
any such returns, claims, audits, or other proceedings until the expiration of
the statutory period of limitations (including extensions) of the taxable
periods to which such documents relate and until the final determination of any
payments which may be required with respect to such periods under this Agreement
and shall make such documents available at the then current administrative
headquarters of such party to the other party or any affiliate thereof, and
their respective officers, employees and agents, upon reasonable notice and at
reasonable times, it being understood that such representatives shall be
entitled to make copies of any such books and records relating to any Company as
they shall deem necessary.  The Purchaser on the one hand, and the Sellers on
the other hand, further agree to permit representatives of the other party or
any affiliate thereof to meet with employees of such party on a mutually
convenient basis in order to enable such representatives to obtain additional
information and explanations of any documents provided pursuant to this Section
7.5.  The Purchaser on the one hand, and the Sellers on the other hand, shall
make available to the representatives of the other party or any affiliate
thereof sufficient work space and facilities to perform the activities described
in the two preceding sentences.  Any information obtained pursuant to this
Section 7.5 shall be kept confidential, except as may be otherwise necessary in
connection with the filing of returns or claims for refund or in conducting any
audit or other proceeding.  Each party shall provide the cooperation and
information required by this Section 7.5 at its own expense.

     7.6  SURVIVAL OF OBLIGATIONS.  The obligations of the parties set forth in
this Article VII shall be unconditional and absolute and shall remain in effect
without limitation as to time.

     7.7  CONFLICT.  In the event of a conflict between the provisions of this
Article VII and any other provisions of this Agreement, the provisions of this
Article VII shall control.  The provisions of Article XI shall not apply to any
Taxes for which any party is liable under this Article VII.

     7.8  TAX ALLOCATION ARRANGEMENTS.  Effective as of the Effective Date, all
liabilities and obligations between any Company on one hand and the Sellers or
their affiliates on the other hand under any tax allocation agreement or
arrangement in effect prior to the Effective Date shall be extinguished in full
(without the necessity of any payment with respect thereto) and any liabilities
or rights existing under any such agreement or arrangement shall terminate and
shall no longer be enforceable.  The Sellers and their affiliates shall execute
any documents necessary to effectuate the provisions of this Section 7.8.


                                      -41-

     7.9  LOSS CARRYOVERS.  To the extent that the Purchaser determines that it
is unable to utilize any net operating loss carryovers and otherwise would elect
to treat the loss carryover as expiring under Treasury Regulation Section
1.1502-32(b)(4), the Purchaser shall jointly enter into an election with the
Sellers pursuant to Treasury Regulation Section 1.1502-20(g)(1) to reattribute
losses of E.E. Black to Morrison Knudsen.  The amount of losses to be
reattributed shall not exceed the taxable loss that would be disallowed by
Treasury Regulation Section 1.1501-20(a)(1) and 1.1502-20(c) as determined by
the Sellers.  The determination of the amount of losses to be reattributed shall
be made by August 31, 1996.


                                  ARTICLE VIII

                         EMPLOYEES AND EMPLOYEE BENEFITS

     8.1  STATUS OF EMPLOYEES.  Except for such employees covered by employment
agreements listed in Schedule 3.18 or subject to collective bargaining
agreements listed in Schedule 3.15 or 3.19 and except for any obligations or
covenants of the Purchaser set forth in Section 8.2 hereof, (a) neither the
Purchaser nor any Company shall have any obligation to continue the employment
of any employee of any Company after the Effective Date, and (b) after the
Effective Date any continued employment of the employees of any Company shall be
on such terms and conditions and include such benefits as the Purchaser shall
deem appropriate in its sole and unlimited discretion (except for those benefits
arising under the 401(k) Plan of Black Construction Corporation ("401(k) Plan"),
the G.W. Murphy Construction Company, Inc. Pension Plan ("Pension Plan") and the
plans referred to as items (a)(3) and (a)(4) on Schedule 3.19 (Guam Plans")).

     8.2  CERTAIN BENEFITS OF EMPLOYEES.  (a)  Except for the 401(k) Plan, the
Pension Plan and the Guam Plans, which shall be continued after the Effective
Date, effective as of the Effective Date, participation by each Company under
all employee benefit plans, programs, practices or arrangements, whether written
or oral, sponsored by the Sellers ("Benefit Plans"), in which any of the
Companies has theretofore participated shall cease; and each participant who is
an employee of any Company immediately after the Effective Date and who was a
participant in any Benefit Plan immediately prior to the Effective Date shall be
entitled to the benefits due to such employee as a result of such termination as
provided in each Benefit Plan (but only if permitted by applicable law).  Each
employee of any Company that participates in the employee benefit plans of the
Purchaser or any affiliate thereof shall be credited under such employee benefit
plans with the same amount of service for eligibility and vesting


                                      -42-
<PAGE>

purposes credited to such employees as of the Effective Date under the employee
benefit plans in which they have theretofore participated, provided such
employee benefit plans are substantially similar to the employee benefit plans
of the Purchaser.  To the extent required by law, the "group health plans"
providing medical coverage to the "covered employees" of the Companies prior to
the Effective Date will provide COBRA health care continuation coverage with
respect to individuals who are "qualified beneficiaries" and who have a
"qualifying event" on or prior to the Effective Date.  The terms used in the
preceding sentence shall have those meanings set forth in Code Section 4980B.
Notwithstanding anything herein to the contrary, the Purchaser intends to
provide health care benefits and coverage to the employees of each Company
(other than the employees of Black Construction who are located in Guam) that
are substantially similar to the health care benefits and coverage that are
provided to the employees of the Purchaser immediately prior to the Effective
Date.

          (b)  Prior to the first anniversary of the Effective Date, the
Purchaser shall, at the sole cost and expense of the Sellers, cause Murphy to
use its best efforts to obtain a favorable determination letter from the
Internal Revenue Service to the effect that the termination of the G. W. Murphy
Construction Company, Inc. Pension Plan ("Pension Plan") does not affect the
qualification of the Pension Plan, and liquidate the trust and disburse Pension
Plan funds to the participants in accordance with the terms and provisions of
the Pension Plan.  Nothing herein shall be construed to relieve the Sellers of
liability arising in connection with claims brought by participants in the
Pension Plan or its beneficiaries with respect to the operation or
administration of such plan prior to the Effective Date.  The Purchaser shall
cooperate with the Sellers in all material respects regarding the filing of the
Pension Plan with the IRS and the PBGC.  The Sellers shall have control over the
content of any such filings and shall select the advisors and other
professionals who will prepare and advise the Purchaser with respect to such
filings.

          (c)  The provisions of this Article VIII to the contrary
notwithstanding, the parties hereto may in the period between the date hereof
and the Effective Date mutually agree to handle the issues addressed therein in
some other manner and, in such event, any provisions agreed to by the parties
hereto in writing pursuant to subsection (c) of this Section 8.2 shall govern.

          (d)  Except with respect to liabilities under the 401(k) Plan, the
Pension Plan, the Guam Plans, the Employment Agreement dated as of November 8,
1992 between Murphy and Gordon L. Scruton, the Deferred Compensation Agreement
dated November 15, 1990 between Murphy and Angel C. Abcede and all obligations
under the collective bargaining agreements listed in Schedule 3.15 or 3.19,
neither the Purchaser


                                      -43-
<PAGE>

nor any Company or their respective affiliates shall have any liability or
obligation with respect to employment matters, any of the Benefit Plans, the
E.E. Black Limited Savings and Retirement Plan or any other liability, whether
contingent or otherwise, relating to or arising out of the employment of
employees or the engagement of independent contractors by any Company or the
Sellers or any of their respective affiliates for periods prior to and including
the Effective Date.

          (e)  The Purchaser and its affiliates will cooperate fully with the
Sellers and allow the Sellers access (in the same manner as set forth in Section
5.3  hereof) with respect to any and all matters relating to the E.E. Black
Limited Savings & Retirement Plan until the latter of (i) the receipt of any
voluntary closing agreement, the application for which is filed with the IRS
within 12 months of the Effective Date, or (ii) three years from the Effective
Date.

                                   ARTICLE IX

                           INVESTIGATION; LIMITATIONS

     9.1  SCOPE OF THE PURCHASER'S INVESTIGATIONS AND WAIVER.  In determining
the Purchase Price to be paid for the MKI Shares, the Purchaser relied upon the
substance of the unaudited April 30, 1995 consolidating balance sheet of the
Companies, a copy of which is included in Schedule 3.7 hereof and the accuracy
of which is being confirmed by the audit provided for in subsection (m) of
Section 6.1 hereof, the express representations, warranties and conditions set
forth in this Agreement and an inspection of the construction equipment and
certain real property owned by the Companies.  ACCORDINGLY, THE PURCHASER IS
WILLING TO DISCLAIM AND NEGATE AND DOES HEREBY DISCLAIM AND NEGATE ANY OTHER
EXPRESSED OR IMPLIED REPRESENTATION OR WARRANTY THAT IS NOT SET FORTH IN THIS
AGREEMENT, THE SELLER RELATED DOCUMENTS OR ANY OTHER AGREEMENT DELIVERED IN
CONNECTION HEREWITH RELATING TO THE ASSETS AND OPERATIONS OF EACH COMPANY.

     9.2  SURVIVAL.  The liability of the Sellers for the breach of the
representations and warranties of the Sellers set forth in Article III hereof
shall be limited to claims for which the Purchaser delivers written notice to
the Sellers on or before (a) the first anniversary date of the Effective Date in
the case of claims relating to Black Construction and Black Micro, (b) the
second anniversary date of the Effective Date in the case of Murphy, MKI and MKP
and (c) the date upon which the assertion of a claim is barred by the statute of
limitations in the case of E.E. Black.  The liability of the Purchaser for the
breach of the representations and warranties of the Purchaser set


                                      -44-
<PAGE>

forth in Article IV hereof shall be limited to claims for which the Sellers
shall deliver written notice to the Purchaser on or before the second
anniversary date of the Effective Date.

                                    ARTICLE X

                                   TERMINATION

     10.1 EVENTS OF TERMINATION.  Subject to the terms of Section 6.3 hereof and
notwithstanding any other provision hereof, this Agreement shall terminate upon
the occurrence of any of the following events:

     (a)  The written consent of the Sellers and the Purchaser;

     (b)  By the Sellers in writing, without liability to the Sellers, if
Purchaser shall (i) fail to perform in any material respect its agreements
contained herein required to be performed by it on or prior to the Effective
Date, or (ii) materially breach any of its representations, warranties or
covenants contained herein, which failure or breach is not cured within ten days
after the Sellers shall have notified the Purchaser of their intent to terminate
this Agreement pursuant to subsection (b) of this Section 10.1;

     (c)  By the Purchaser in writing, without liability to the Purchaser, if
the Sellers shall (i) fail to perform in any material respect their agreements
contained herein required to be performed by them on or prior to the Effective
Date, or (ii) materially breach any of their representations, warranties or
covenants contained herein, which failure or breach is not cured within ten days
after the Purchaser has notified the Sellers of its intent to terminate this
Agreement pursuant to subsection (c) of this Section 10.1;

     (d)  By either the Sellers or the Purchaser in writing, without liability,
if there shall be any order, writ, injunction or decree of any court or
governmental or regulatory agency binding on the Purchaser or the Sellers, which
prohibits or restrains the Purchaser or the Sellers from consummating the
transactions contemplated hereby, provided that the Purchaser and the Sellers
shall have used their best efforts to have any such order, writ, injunction or
decree lifted and the same shall not have been lifted within 30 days after entry
by any such court or governmental or regulatory agency; or

     (e)  The written notice from the Purchaser to the Sellers or the Sellers to
the Purchaser if the Closing has not occurred, without fault on any party's
part, by October 31, 1995.


                                      -45-

     10.2 EFFECT OF TERMINATION.  The following provisions shall apply in the
event of a termination of this Agreement:

     (a)  If this Agreement is terminated by the Sellers or by the Purchaser as
permitted under Section 10.1 hereof and not as the result of the negligent or
willful failure of any party to perform its obligations hereunder, such
termination shall be without liability to any party to this Agreement or any
shareholder, director, officer, employee, agent or representative of such party.

     (b)  The Purchaser and the Sellers acknowledge that the MKI Shares are not
readily available in the open market and the assets of each Company are unique
and specifically identifiable.  Accordingly, the Purchaser and the Sellers
further agree and stipulate that if the Closing does not occur because of the
willful failure of the Sellers, on the one hand, or the Purchaser, on the other
hand, to perform their respective obligations hereunder, (i) monetary damages
and any other remedy at law will not be adequate, (ii) the non-defaulting party
shall be entitled to specific performance as the remedy for such breach, (iii)
each party hereto agrees to waive any objection to the remedy of specific
performance, (iv) each party agrees that the granting of specific performance by
any court will not be deemed to be harsh or oppressive to the party who is
ordered specifically to perform its obligations under this Agreement, and (v) in
connection with any action for specific performance, the prevailing party shall
be entitled to reasonable attorneys' fees and other costs of prosecuting or
defending such action.

     (c)  The right to seek specific performance hereunder shall not preclude
any party to seek any other remedy at law or in equity.

                                   ARTICLE XI

                                 INDEMNIFICATION

     11.1 INDEMNIFICATION OF THE SELLERS.  The Purchaser, from and after the
Effective Date, shall protect, indemnify and hold the Sellers harmless from and
against any and all Damages suffered by the Sellers as a result of, caused by,
arising out of, or in any way relating to (a) any misrepresentation, breach of
warranty, or nonfulfillment of any agreement or covenant on the part of the
Purchaser under this Agreement, any Purchaser Related Document or any
misrepresentation in or omission from any list, schedule, certificate, or other
instrument furnished or to be furnished to the Sellers by the Purchaser pursuant
to the terms of this Agreement or (b) the performance (or lack of performance)
by any Company after the Effective Date of its obligations under any


                                      -46-
<PAGE>

contract that was in existence prior to the Effective Date, other than any
contract representing part of the Retained Assets.

     11.2 INDEMNIFICATION OF THE PURCHASER.  Subject to the limitations set
forth in Section 9.2 hereof, the Sellers, jointly and severally, shall protect,
indemnify and hold the Purchaser and each Company harmless from and against any
and all Damages suffered by the Purchaser or any Company as a result of, caused
by, arising out of, or in any way relating to (a) any misrepresentation, breach
of warranty, or nonfulfillment of any agreement or covenant (including without
limitation Section 1.3 hereof) on the part of the Sellers under this Agreement,
any Seller Related Document or any misrepresentation in or omission from any
list, schedule, certificate, or other instrument furnished or to be furnished to
the Purchaser by the Sellers or any Company pursuant to the terms of this
Agreement or (b) the performance (or lack of performance) by any Company of any
contractual obligation that is performable by it on or prior to the Effective
Date, including without limitation any obligation arising from a contract
representing part of the Retained Assets.

     11.3 DEMANDS.  Each indemnified party hereunder agrees that promptly upon
its discovery of facts giving rise to a claim for indemnity under the provisions
of this Agreement, including receipt by it of notice of any demand, assertion,
claim, action or proceeding, judicial or otherwise, by any third party (such
discovery of facts or third-party action being collectively referred to herein
as a "Matter"), with respect to any Matter as to which it claims to be entitled
to indemnity under the provisions of this Agreement, it will give prompt notice
thereof in writing to the indemnifying party, together with a statement of such
information respecting any of the foregoing as it shall have.  Such notice shall
include a formal demand for indemnification under this Agreement.  The
indemnifying party shall not be obligated to indemnify the indemnified party
with respect to any Matter if the indemnified party knowingly failed to notify
the indemnifying party thereof in accordance with the provisions of this
Agreement in sufficient time to permit the indemnifying party or its counsel to
defend against such Matter and to make a timely response thereto including,
without limitation, any responsive motion or answer to a complaint, petition,
notice or other legal, equitable or administrative process relating to the
Matter, only insofar as such knowing failure to notify the indemnifying party
has actually resulted in prejudice or damage to the indemnifying party.

     11.4 RIGHT TO CONTEST AND DEFEND.  The indemnifying party shall be entitled
at its cost and expense to contest and defend by all appropriate legal
proceedings any Matter with respect to which it is called upon to indemnify the
indemnified party under the provisions of this Agreement; provided, that notice
of the intention so to contest


                                      -47-
<PAGE>

shall be delivered by the indemnifying party to the indemnified party within 20
days from the date of receipt by the indemnifying party of notice by the
indemnified party of the assertion of the Matter.  If the indemnifying party has
elected to assume the defense of any Matter, except as otherwise provided in
this Section 11.4, the indemnifying party will not be liable for any legal
expenses subsequently incurred by the indemnified party in connection with the
defense thereof; provided, however, that if the indemnifying party fails to
notify the indemnified party of its intent to assume the defense of the Matter
within such 20-day period, the indemnified party may assume its own defense, and
the indemnifying party will be liable for any reasonable expenses thereof.  Any
such contest may be conducted in the name and on behalf of the indemnifying
party or the indemnified party as may be appropriate.  Such contest shall be
conducted by reputable counsel employed by the indemnifying party, but the
indemnified party shall have the right but not the obligation to participate in
such proceedings and to be represented by counsel of its own choosing at its
sole cost and expense.  The indemnifying party shall have full authority to
determine all action to be taken with respect thereto; provided, however, that
the indemnifying party will not have the authority to subject the indemnified
party to any obligation whatsoever, other than the performance of purely
ministerial tasks or obligations not involving material expense.  If the
indemnifying party does not elect to contest any particular Matter, the
indemnifying party shall be bound by the result obtained with respect thereto by
the indemnified party.  At any time after the commencement of the defense of any
Matter, the indemnifying party may request the indemnified party to agree in
writing to the abandonment of such contest or to the payment or compromise by
the indemnified party of the asserted Matter, whereupon such action shall be
taken unless the indemnified party reasonably determines that the contest should
be continued, and so notifies the indemnifying party in writing within 15 days
of such request from the indemnifying party.  If the indemnifying party
ultimately determines that the contest should be continued, all legal fees and
disbursements and other expenses associated with continuing the contest shall be
borne by the indemnifying party.  If the indemnified party determines that the
contest should be continued, the indemnifying party shall be liable hereunder
only to the extent of the amount that the other party to the contested Matter
had agreed unconditionally to accept in payment or compromise as of the time the
indemnifying party made its request therefor to the indemnified party.  The
indemnified party shall not settle any Matter for which it is seeking
indemnification without the prior written consent of the indemnifying party
(which consent shall not be unreasonably withheld).

     11.5 COOPERATION.  If requested by the indemnifying party, the indemnified
party agrees to cooperate, including, without limitation, providing reasonable
access to its books and records relating to the Matter, with the indemnifying
party and its counsel in contesting any Matter that the indemnifying party
elects to contest or, if appropriate,


                                      -48-
<PAGE>

in making any counterclaim against the person asserting the Matter, or any
cross-complaint against any person, and the indemnifying party will reimburse
the indemnified party for any expenses incurred by it in so cooperating.  At no
cost or expense to the indemnified party, the indemnifying party shall cooperate
with the indemnified party and its counsel in contesting any Matter with respect
to all reasonable requests for such cooperation.

     11.6 RIGHT TO PARTICIPATE.  The indemnified party agrees to afford the
indemnifying party and its counsel the opportunity to be present at, and to
participate in, conferences with all persons, including governmental
authorities, asserting any Matter against the indemnified party or conferences
with representatives of or counsel for such persons.

     11.7 PAYMENT OF DAMAGES.  The indemnifying party shall pay to the
indemnified party in immediately available funds any amounts to which the
indemnified party may become entitled by reason of the provisions of this
Agreement, such payment to be made within five days after any such amounts are
finally determined either by mutual agreement of the parties hereto or pursuant
to the final unappealable judgment of a court of competent jurisdiction. In
calculating any amount to be paid by an indemnifying party by reason of the
provisions of this Agreement, the amount shall be reduced by all tax benefits
and other reimbursements credited to or received by the other party related to
the Damages.

     11.8 LIMITATIONS ON INDEMNIFICATION.  The Sellers shall not be liable to
indemnify the Purchaser or any Company for Damages under Section 11.2 hereof
unless the aggregate amount of Damages for which the Sellers would, but for the
provisions of this Section 11.8, be liable exceeds, on an aggregate basis,
$25,000, and then only to the extent of any such excess and in no event shall
the total liability of the Sellers hereunder exceed $855,000 in the aggregate;
provided that notwithstanding the foregoing, the Sellers shall be fully liable
to indemnify the Purchaser and the Companies for Damages as a result of, caused
by, arising out of, or in any way relating to (a) any Taxes for which the
Sellers are liable under Article VII, (b) the breach by the Sellers of the
representations or covenants set forth in Sections 1.3(c), 1.3(d), 1.4, 3.10 and
3.23 hereof and (c) the agreement contemplated by subsection (l) of Section 6.1
hereof.

arising out of the preparation and maintenance of any data rooms established in
connection with the offering for sale of the stock or assets of one or more of
the Companies, and all legal and accounting fees and expenses incurred in

venue or based on the grounds of FORUM NON CONVENIENS, which it may now or
hereafter have to the bringing of any legal action in that jurisdiction;
PROVIDED, HOWEVER, that each of the Sellers and the Purchaser may assert in a
legal action in any other jurisdiction or venue each defense, third-party claim
or similar claim that, if not so asserted in such legal action, may thereafter
not be asserted by such party in an original legal action in the courts referred
to in clause (i) above.

     12.5 PUBLIC STATEMENTS.  The parties hereto shall consult with each other
and no party shall issue any public announcement or statement with respect to
the transactions contemplated hereby without the consent of the other parties,
unless the party desiring to make such announcement or statement, after seeking
such consent


                                      -51-
<PAGE>

from the other parties, obtains advice from legal counsel that a public
announcement or statement is required by applicable law.

     12.6 FORM OF PAYMENT.  All payments hereunder shall be made in United
States dollars and, unless the parties making and receiving such payments shall
agree otherwise or the provisions hereof provide otherwise, shall be made by
wire or interbank transfer of immediately available funds by 12:00 Noon, Boise,
Idaho time, on the date such payment is due to such account as the party
receiving payment may designate at least three business days prior to the
proposed date of payment.

     12.7 ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS.  This Agreement, together
with schedules attached hereto, and any documents delivered pursuant hereto,
constitutes the entire agreement between the parties hereto pertaining to the
subject matter hereof and supersedes all prior agreements, understandings,
negotiations and discussions, whether oral or written, of the parties,
including, without limitation, that certain Letter of Intent, dated July 21,
1995, as amended, by and between the Purchaser and Morrison Knudsen, and there
are no warranties, representations or other agreements between the parties in
connection with the subject matter hereof except as set forth specifically
herein or contemplated hereby.  No supplement, modification or waiver of this
Agreement shall be binding unless executed in writing by each party to be bound
thereby.  No waiver of any of the provisions of this Agreement shall be deemed
or shall constitute a waiver of any other provision hereof (regardless of
whether similar), nor shall any such waiver constitute a continuing waiver
unless otherwise expressly provided.

     12.8 BINDING EFFECT AND ASSIGNMENT.  This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective permitted
successors and assigns; but neither this Agreement nor any of the rights,
benefits or obligations hereunder shall be assigned, by operation of law or
otherwise, by any party hereto without the prior written consent of the other
parties; provided that the Purchaser may assign all of its rights, privileges
and obligations hereunder to any direct or indirect wholly-owned subsidiary of
the Purchaser organized under the laws of any of the United States.  No such
assignment shall relieve the Purchaser of any of its obligations under this
Agreement.  Nothing in this Agreement, express or implied, is intended to confer
upon any person or entity other than the parties hereto and their respective
permitted successors and assigns, any rights, benefits or obligations hereunder.

     12.9 SEVERABILITY.  If any one or more of the provisions contained in this
Agreement or in any other document delivered pursuant hereto shall, for any
reason, be held to be invalid, illegal or unenforceable in any respect, such
invalidity, illegality or


                                      -52-
<PAGE>

unenforceability shall not affect any other provision of this Agreement or any
other such document.  Furthermore, in lieu of such illegal, invalid or
unenforceable provision, there shall be added automatically as part of this
Agreement, a provision as similar in its term to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.

     12.10     DEFINITION OF "MATERIAL".  The misstatement or omission of an
item of data in or from a representation or warranty in a section of this
Agreement, or in or from any list, schedule, certificate or other instrument
furnished pursuant to the terms of this Agreement (or the failure to perform an
obligation set forth in a section of this Agreement), shall be considered
"material", "materially adverse" or other words and phrases of similar purport
if such misstatement or omission, when aggregated with all other misstatements
or omissions in or from the same section of this Agreement, or such list,
schedule, certificate or other instrument (or such failure, when aggregated with
all other failures under the same section), results in indemnifiable Damages
under Article XI hereof in excess of $25,000 without regard to the provisions of
Section 11.8 hereof.

     12.11     HEADINGS AND SCHEDULES.  The headings of the several Articles and
Sections herein are inserted for convenience of reference only and are not

schedules referred to herein are attached hereto and incorporated herein by this

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

     EXECUTED as of the date first set forth above.
