MORRISON KNUDSEN CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(ALL DOLLAR AMOUNTS IN THOUSANDS)

THE TERM "CORPORATION" AS USED IN THIS QUARTERLY REPORT INCLUDES MORRISON
KNUDSEN CORPORATION AND ITS CONSOLIDATED SUBSIDIARIES UNLESS OTHERWISE
INDICATED.

1.   BASIS OF PRESENTATION AND MANAGEMENT'S PLANS


In March 1995, the Corporation announced its decision to sell its 65% ownership
interest in MK Rail Corporation ("MK Rail"). The accompanying consolidated
financial statements and financial statement footnotes as of and for the three
and six month periods ended June 30, 1995 and 1994 give effect to the
anticipated sale of the Corporation's 65% ownership interest in MK Rail. The
disposal of the MK Rail segment has been accounted for as a discontinued
operation at March 31, and June 30, 1995 and accordingly, its results of
operations and cash flows are segregated and reported as discontinued operations
in the accompanying consolidated statements of operations and cash flows for the
three and six month periods ended June 30, 1995. The assets and liabilities of
MK Rail have been segregated on the consolidated balance sheet at June 30, 1995,
from their historical classifications consistent with the presentation of the
related results of operations of MK Rail as a separate item in the accompanying
statements of operations. Prior period consolidated financial statements have
been restated to present MK Rail as a discontinued operation. The comparative
consolidated balance sheet and financial statement footnotes included herein as
December 31, 1994 amounts have been derived from the audited balance sheet and
financial statement footnotes at December 31, 1994. See Note 2. "Changes in
Business - Discontinued Operations".

The accompanying consolidated financial statements include the accounts of the
Corporation and its majority-owned subsidiaries. Investments in 20 percent to 50
percent owned companies and joint ventures are accounted for by the equity
method. The Corporation's proportionate share of joint venture revenue, cost of
revenue and operating income (loss) is included in the consolidated statements
of operations. Intercompany accounts and transactions have been eliminated.

The consolidated financial statements have been prepared without audit, pursuant
to the rules and regulations of the Securities and Exchange Commission. Certain
financial information and footnote disclosures normally included in annual
financial statements have been condensed or omitted pursuant to such rules and
regulations. These consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
included in the Corporation's Annual Report to Stockholders or the Corporation's
Annual Report on Form 10-K for the year ended December 31, 1994.

The unaudited consolidated financial statements included herein reflect all
adjustments consisting of normal recurring adjustments which are, in the opinion
of management, necessary to a fair presentation of the results of operations and
cash flows for the interim period. The results of operations for the six month
period ended June 30, 1995 are not necessarily indicative of the results to be
expected for the full year.

The Corporation's consolidated financial statements have been prepared on the
basis that it will continue as a going concern, which contemplates the
realization of asset values and the satisfaction of liabilities in the normal
course of business. There are certain conditions that raise substantial doubt
about the Corporation's ability to continue as a going concern:

- -    The Corporation reported net losses of $63,707 and $349,635 for the six
     month period ended June 30, 1995 and year ended December 31, 1994,
     respectively.

- -    Net cash used by the Corporation's operating activities was $117,380 and
     $142,536 for the six month period ended June 30, 1995 and year ended
     December 31, 1994, respectively.

- -    At June 30, 1995 and December 31, 1994 stockholders' equity was $3,908 and
     $62,893, respectively, and included retained deficits of $311,916 and
     $248,209 at June 30, 1995 and December 31, 1994, respectively.

- -    At June 30, 1995 and December 31, 1994 there were working capital deficits
     of $81,707 and $108,465, respectively.

- -    The Corporation expects significant negative cash flow from operations in
     1995 and will require additional funding to cover expected negative cash
     flows.


                                       I-5

<PAGE>

The Corporation received bank waivers on certain covenant defaults under its
credit agreements, additional funding of $50,000 from its banks (of which
$31,200 was repaid prior to June 30, 1995) and received extensions of all the
bank credit agreements through July 31, 1995. On August 11, 1995, the
Corporation its bank lenders and sureties agreed as of July 31, 1995 to a
restructuring of the Corporation's existing indebtedness and the establishment
of new interim credit facilities, expiring September 1, 1995 to advance funds to
the Transit segment prior to its planned divestiture as a limited liability
company, anticipated by September 1, 1995. The restructuring provides for an
increase in the amount of the bridge loans from $122,100 to $129,000.
Outstanding borrowings under the bridge loans are due and payable on March 31,
1996. The restructuring agreements require the repayment of $100,000 of the
antecedent bank debt on September 30, 1996 and the balance payable on December
31, 1996. In addition to these required payments, the restructuring agreements
also provide for the Corporation to repay (i) net cash proceeds in excess of
$10,000 received from the sales of certain businesses and assets currently held
for sale, (ii) any prepayments or repayments received by the Corporation on the
$52,200 note receivable from MK Rail, and (iii) any tax refunds received.

In addition, in July 1995, the Corporation reached a preliminary agreement
("transit agreement") with its surety-syndicate-manager and letter-of-credit
banks ("LC banks") to fund the Transit segment's anticipated cash flow
deficiency. The transit agreement contemplates, among other matters, the sharing
of Transit's cash flow deficiency between the Corporation and its surety
syndicate and LC  banks, including limits on the Corporation's funding
requirements and participation in future operating losses.

The restructuring provides ongoing indebtedness of the Corporation to the lender
banks and its sureties  to be secured and the Corporation will grant stock
purchase warrants to the lender banks and sureties for unissued common stock up
to 14,859,430 shares. In connection with the restructuring the Corporation would
also receive limited bonding capacity.

The Corporation believes that the funds available under the restructuring
agreements, together with the anticipated net proceeds from sales of businesses
and assets currently held for sale will provide sufficient liquidity until
September 1996 when the Corporation believes, a substantial recapitalization
through an equity infusion or new debt will be required. Unless the Corporation
is able to obtain alternative sources of cash to meet the mandatory interim
$100,000 repayment of the antecedent bank debt on September 30, 1996 required
under the restructuring, the Corporation may, among other alternatives, seek
protection from its creditors under the United States Bankruptcy Code. The
Corporation believes that, in such circumstances, the ability, if any, of its
stockholders to recover their investments would be significantly impaired and
that any such recovery, if available, would be substantially delayed.

The Corporation's ability to continue as a going concern is dependent upon the
Corporation successfully completing a recapitalization by obtaining additional
debt or equity capital and returning the Corporation to profitable operations.
In this connection, the Corporation has adopted the following operating and
management plans to:

- -    Sell non-core businesses and use the cash proceeds to substantially reduce
     the debt burden. See Note 2. "Changes in Business" and Note 7. "Short-Term
     Debt - New and Amended Credit Facilities".

- -    Successfully resolve the stockholders' litigation. See Note 9. "Commitments
     and Contingencies - Legal Proceedings" and Item 1. "Legal Proceedings" in
     Part II of this Quarterly Report on Form 10-Q.

- -    Continue to obtain new, profitable contracts and to generate positive cash
     flow from continuing operations in 1996 and beyond.

Although the results of these actions cannot be predicted with certainty,
management believes that if the Corporation can continue to receive the
cooperation of its banks and surety syndicate, and can obtain additional debt or
equity financing that the Corporation has the ability ultimately to return to
profitability and repay or refinance the existing indebtedness.

2.   CHANGES IN BUSINESS

The Corporation decided in the fourth quarter of 1994 and the first quarter of
1995 to pursue the sale of certain of its consolidated subsidiaries and
investments in unconsolidated affiliates.

DISCONTINUED OPERATIONS: In March 1995, the Corporation adopted a plan to sell
its 65% ownership interest in MK Rail Corporation. The sale is expected to be
completed no later than March 31, 1996. Accordingly, the Corporation has
accounted for the planned divestiture of MK Rail as a discontinued operation,
and the accompanying consolidated financial statements have been reclassified to
report the net assets, results of operations and cash flows of MK Rail
separately. Prior period consolidated financial statements have been restated to
present MK Rail as a discontinued operation. The Corporation has recorded an
estimated loss on sale of its ownership interest in MK Rail based upon the
information available in the circumstances. However, there can be no assurance
that the net proceeds realized by the Corporation from the ultimate sale of its
ownership interest therein will not be less than the estimated fair value
assumed in this estimate.

Summary results of operations for the discontinued MK Rail segment for the six
months in the periods ended June 30, 1995 and 1994 follows:

(1) Included in the net loss for the six months ended June 30, 1995 is an
aggregate after-tax loss of $7,285 in connection with MK Rail's wholly-owned
subsidiary Morrison Knudsen Corporation of Australia, Ltd. ("MKA"). MK Rail
recognized a $4,485 operating loss from MKA's operations and a $2,800 loss on
sale of its ownership interest in MKA to the Corporation. See Note 10.

MK RAIL INTERCOMPANY AGREEMENT: On June 15, 1995, the Corporation entered into
an agreement with MK Rail regarding the amount of intercompany indebtedness owed
by MK Rail to the Corporation and certain other matters. The agreement resulted
in the Corporation reducing its receivable from MK Rail through a capital
contribution of $29,500. The remaining balance of $52,200 was converted into a
note, with interest at the prime rate, due in 2000 with earlier repayments under
certain default and change-of-interest conditions. The outstanding balance of
the intercompany debt is due and payable in full upon the acquisition of all of
the common stock or substantially all of the assets of MK Rail by a third party.
The estimated loss on sale of MK Rail recognized includes the effect of this
additional capital contribution to MK Rail.

ASSETS OF SUBSIDIARIES AND INVESTMENTS HELD FOR SALE: The assets and liabilities
of the Corporation's subsidiaries - McConnell Dowell Corporation, Ltd., MK
Investments, Inc. (North Pacific construction operations) and Western Aircraft,
Inc. and the Corporation's investment in Amerbank, have been segregated on the

DISPOSITIONS IN 1994

WRITE OFF OF INVESTMENT IN TEXAS TGV CORPORATION ("TEXAS TGV"): Texas TGV was
awarded a franchise in May 1991 to finance, construct and operate a high speed
rail system in Texas. Because Texas TGV failed to provide equity financing by
December 31, 1993 as required under the franchise agreement and since its
efforts to extend the deadline or to negotiate amendments to the franchise
agreement with the Texas High Speed Rail Authority in early 1994 were
unsuccessful, the Corporation abandoned the project and wrote-off its $13,828
investment in Texas TGV in June 1994.

SALE OF INTEREST IN STRAIT CROSSING DEVELOPMENT, INC. ("SCDI"): In October 1993,
Strait Crossing Development, Inc., a 45% owned unconsolidated subsidiary,
entered into a development agreement with the government of Canada to design,
construct and operate for 35 years an 8.4 mile long toll bridge linking the
Atlantic Provinces of New Brunswick and Prince Edward Island. On March 31, 1994,
the Corporation entered into an agreement to sell a portion of its ownership
interest in SCDI to a third party for $1,301 cash and a $3,576 note receivable
with interest at 7% per annum, due and payable on the earlier of the date of
final completion of the toll bridge or May 31, 1998. The sale decreased the
Corporation's ownership interest in SCDI from 45% to 36%. The Corporation
recognized a pretax gain of $4,877 on the change of interest.

5.   CONSTRUCTION JOINT VENTURES

The Corporation has from time to time entered into a number of partnership
arrangements with other contractors commonly referred to as "joint ventures".
Construction joint ventures frequently have a short life span, since they are
designed and created for the sole purpose of bidding on, negotiating for, and
completing one specific project and are liquidated when the project is
completed. The number of joint ventures in which the Corporation participates
and the size, scope and duration of the projects vary between periods. Specific
joint ventures change from period to period, and the comparability of the
following summary financial information between periods may not be meaningful.
The following table presents summarized financial information of the
construction joint ventures on a combined 100 percent basis at June 30, 1995 and
December 31, 1994 and for the six months in the periods ended June 30, 1995 and
1994.

</TABLE>

The weighted average interest rates on short-term borrowings outstanding of
$307,617 at June 30, 1995 and $192,152 at December 31, 1994 were 10.4% and 6.6%,
respectively.

CREDIT FACILITY: On April 11, 1995, the Corporation and its current lender banks
entered into a Credit Facility under which certain of the lender banks provided
secured bridge loans of $110,000. The Facility included establishment of $50,000
in new borrowing capacity and absorption of a then existing $60,000 accounts
receivable purchase agreement. The Credit Facility also waived until May 31,
1995, non-compliance with various financial covenants under the unsecured
antecedent bank debt agreement. Interest on the outstanding unsecured antecedent
bank debt, equal to the prime rate (9% at June 30, 1995), is generally payable
on the last day of each month. On April 25, 1995 the Credit Facility was amended
to include an additional accounts receivable facility of $12,100. The $122,100
outstanding under the  Credit Facility was due and payable on May 31, 1995.
Effective June 1, 1995, the Credit Facility was amended to (i) extend the loan
termination date and the waivers from May 31, 1995 to July 31, 1995 and (ii)
require the Corporation to repay $31,200 of the secured bridge loans by July 31,
1995. The Corporation repaid $31,200 prior to June 30, 1995. Interest on the
outstanding $122,100 secured bridge loans, equal to the prime rate plus three
percent per annum (12% at June 30, 1995), is payable on the last day of each
month and on July 31, 1995. The Credit Facility specifies certain events of
default. These events of default arise upon the occurrence of, among other
things, (i) the Corporation's failure to pay amounts owing under the secured
bridge loans (ii) breaches of covenants, representations and warranties and
(iii) other events that customarily constitute events of default under loan
agreements similar to the secured bridge loans.

NEW AND AMENDED CREDIT FACILITIES: On August 11, 1995, the Corporation its bank
lenders and sureties agreed as of July 31, 1995 to (i) a restructuring of the
Corporation's existing indebtedness (ii) establishment of an interim Revolving
Credit Facility, expiring September 1, 1995, to advance funds of up to $15,000
with interest at the prime rate to the Transit segment to finance its operations
in connection with its Metra contract, and (iii) establishment of an Interim
Loan Facility, expiring September 1, 1995, to advance funds of up to $25,000 to
the Transit segment prior to its planned divestiture as a limited liability
company, anticipated by September 1, 1995. Funds advanced to the Transit segment
bear interest at the prime rate and are to be used solely for financing its
operations in connection with its non-Metra contracts and are guaranteed by the
Corporation's principal surety.

In connection with the restructuring, the bank lenders increased the amount of
the secured bridge loans from $122,100 to $129,000. Amounts borrowed are to be
used for non-Transit-segment working capital purposes. As of July 31, 1995 the
Corporation had unused borrowing capacity under the secured bridge loans of
$52,287. Outstanding borrowings under the secured bridge loans are due and
payable on March 31, 1996 and bear interest at a rate equal to the prime rate
plus three percent. Interest is payable on the last day of each calendar month
and on March 31, 1996. The Corporation paid a closing fee of $1,290 on August
11, 1995.

The restructuring permits the deferral of principal payments on the antecedent
bank debt from July 1, 1995 until December 31, 1996, except, the Corporation is
required to repay $100,000 on September 30, 1996 plus interest and periodic bank
fees accrued to that date. Outstanding borrowings under the antecedent bank debt
bear interest at the prime rate. Interest accrued on outstanding borrowings
after July 1, 1995, may be deferred and paid in six equal monthly installments,
together with accrued interest thereon at the prime rate on the unpaid interest,
commencing April 30, 1996 unless repaid with optional principal prepayments.
Under the restructuring agreements, the antecedent bank debt was secured by
security interests and mortgages on substantially all of the assets of the
Corporation and certain of its subsidiaries.

<PAGE>

In addition to the required repayment of the outstanding balance under the
bridge loans at March 31, 1996 and $100,000 repayment under the antecedent bank
debt at September 30, 1996, the restructuring agreements also provide for (i)
optional prepayments and (ii) mandatory prepayments. The Corporation may, at its
option, prepay at any time all or part of the amount outstanding under the
antecedent bank debt and bridge loans. The Corporation must prepay (i) net cash
proceeds in excess of $10,000 received from the sales of certain businesses and
assets currently held for sale, (ii) any prepayments or repayments received by
the Corporation on the $52,200 note receivable from MK Rail, and (iii) any tax
refunds received.

In connection with the restructuring, the Corporation as of July 31, 1995,
granted to the bank lenders two stock purchase warrants to acquire a total of
14,029,391 shares of unissued common stock at an exercise price of $6.75 per
share. The warrants may be exercised for all or any part thereof at December 31,
1996, or earlier upon a payment default on the antecedent bank debt, but not
later than July 31, 2000. The Corporation's obligation for the warrant covering
9,415,696 shares can be (i) eliminated if the Corporation repays the outstanding
balance of the antecedent bank debt by June 30, 1996 or (ii) reduced by 50% if
repaid during the period from July 1, 1996 through September 30, 1996. The
Corporation's obligation for the warrant covering 4,613,695 shares can be (i)
eliminated if the Corporation repays the outstanding balance of all indebtedness
in connection with Transit segment's Metra contract by June 30, 1996 or (ii)
reduced by 50% if repaid during the period from July 1, 1996 through December
31, 1996 or (iii) reduced by 25% if repaid during the period from January 1,
1997 through June 30, 1997. The Corporation's sureties were also granted a stock
purchase warrant to acquire a total of 830,039 shares of unissued common stock
at an exercise price of $6.75 per share. The sureties warrant may be exercised
for all or any part thereof at December 31, 1996, or earlier upon a payment
default with respect to the Corporation's reimbursement obligation to its
sureties for Transit segment liabilities, but not later than July 31, 2000. The
Corporation's obligation for the sureties warrant can be (i) eliminated if the
Corporation satisfies its reimbursement obligation to the sureties for their
Transit segment liabilities by June 30, 1996 or (ii) reduced by 50% if satisfied
during the period from July 1, 1996 through September 30, 1996.

9.   COMMITMENTS AND CONTINGENCIES

LEGAL PROCEEDINGS:  The Corporation and several of its current and former
officers and the Corporation's auditors were named as defendants in lawsuits
asserted by certain stockholders who claim to represent a class of stockholders
that purchased shares of the Corporation's common stock between October 15, 1993
and March 20, 1995 (the "MK Securities Class Actions"). These class action
complaints, which were first filed on July 28, 1994, purport to present claims
under federal and state securities and other laws and seek equitable relief and
unspecified damages for losses resulting from alleged improper disclosures
during the class periods. The Corporation, MK Rail, several of MK Rail's
officers and directors, and the managing underwriters of MK Rail's initial
public offering were named as defendants in lawsuits asserted by stockholders
who claim to represent a class of stockholders that purchased shares of MK
Rail's common stock between April 26, 1994 and September 29, 1994 (the "MK Rail
Securities Class Actions"). The complaints, which were first filed on October
20, 1994, purport to present claims under the federal securities laws and seek
equitable relief and unspecified damages for losses resulting from, among other
things, alleged improper disclosures during the class period. Certain of the
Corporation's current and former directors and officers have been named as
defendants in thirteen derivative actions which have been filed in state courts
in Idaho and Delaware between February 13 and June 2, 1995. The Corporation is a
nominal defendant in each of these actions. Plaintiffs assert that the
defendants authorized or acquiesced in wrongful conduct on the part of the
Corporation's former chairman and failed to properly supervise his activities,
and also allege waste of corporate assets through payment of excessive
compensation.

Preliminary agreements as to the principal economic terms of a settlement of
securities class actions and derivative actions were reached in June 1995,
subject, among other things, to approval by the appropriate courts. The $69,000
settlement will include payment of cash and the issuance of stock. The $40,000
cash settlement will be paid by the Corporation's and MK Rail's insurers. The
Corporation and MK Rail will issue new common and preferred stock in the amounts
of $25,000 and $4,000, respectively, based on predetermined stock prices.
Effective December 1994, the Corporation recognized an aggregate pretax charge
of $25,000 for the estimated costs of the settlement. The estimated liability
for the $25,000 settlement is included in the balance sheets at December 31,
1994 and June 30, 1995 as a non-current liability. Assuming court approval and
issuance of the stock, the $25,000 will be reflected in stockholders' equity.
However, there can be no assurance that all the parties to the preliminary
agreements will agree on the terms of the final settlement or that such final
settlement will be approved by the appropriate courts. Although the Corporation
has recorded its estimate of the minimum liability, the ultimate outcome of the
litigation cannot presently be determined. Accordingly, no provision for
additional loss that may result upon resolution of this matter has been made in
the consolidated financial statements.

On February 7, 1995 the Corporation was named a defendant in lawsuits by former
stockholders of Touchstone. The plaintiffs allege that certain financial
statements of the Corporation, upon which they based their decision to exchange
their shares for shares of common stock of the Corporation, were misleading. The
plaintiffs purport to state claims for violation of federal and state securities
laws and also assert certain common law and contractual claims. The Touchstone
actions are at a preliminary state of proceedings and accordingly, the outcome
cannot be predicted with any certainty. As a result, the Corporation cannot make
a determination if the affects of the Touchstone actions will have a material
adverse affect on the Corporation's financial position.


                                      I-14

<PAGE>

The Corporation is a defendant in a number of other legal actions of the type
normally associated with the Corporation's business and involving claims for
damages. The Corporation is of the opinion that such actions will not result in
any material adverse effect on the Corporation's financial position.

LETTERS OF CREDIT:  The Corporation was contingently liable, in the normal
course of business, for $298,000 in standby and financial letters of credit not
reflected in the accompanying financial statements at June 30, 1995 for contract
performance guarantees on a number of Engineering and Construction and Transit
segment contracts.

DISCONTINUED SHIPBUILDING OPERATIONS:  In April 1989, the Corporation sold its
interest in National Steel and Shipbuilding Company ("NASSCO") and in June 1994,
the Corporation renegotiated and amended the April 1989 sale agreement with
NASSCO. Under the terms of the amended agreement the Corporation will provide
NASSCO a $21,000 credit facility continuing for a period of three years after
completion of a U.S. Navy contract, expected in mid 1996, and NASSCO will
relinquish its right to require the Corporation to accept repayment in NASSCO
preferred stock for any balance outstanding under the credit facility. At June
30, 1995, NASSCO had no balance outstanding under the Corporation's credit
facility.

At June 30, 1995, the Corporation was contingently liable up to a maximum of
$21,000 on a bank credit facility obtained by NASSCO. The balance outstanding
under NASSCO's bank credit facility at June 30, 1995 was $21,000. The
Corporation's credit facility is reduced by the amount of funds borrowed under
NASSCO's bank credit facility. The Corporation has also guaranteed $21,000 of
NASSCO's port facility bonds until not later than December 1, 2002, and
guaranteed $1,793 of NASSCO's federal workers' compensation bonds. NASSCO's
floating dry dock is pledged as collateral for the $21,000 port facility bonds.

DISCONTINUED REAL ESTATE OPERATIONS:  At June 30, 1995, the Corporation was
contingently liable for $30,980 of bank loans in connection with commercial real
estate operations discontinued in 1987. Net assets of the real estate operations
of Emkay Development Company, Inc. ("Emkay"), a subsidiary of the Corporation,
are included in the accompanying balance sheets under the caption "Other
investments and assets" and consist of:

The notes receivable are due at various dates from 1995 through 1999 at interest
rates ranging from 6.4% to 6.9%. Most of the notes are collateralized by deeds
of trust.

On March 31, 1995, Emkay failed to make a scheduled $5,000 payment under one of
two unsecured loan agreements with banks. The Corporation and the banks have
reached a Forbearance Agreement which, among other things, provides for the
waiving of existing defaults resulting from the nonpayment of the $5,000 owed
under the loan agreement and the granting to the banks of security interests and
mortgages in all of Emkay's real estate and other assets, and the repayment of
the outstanding loan balance by June 30, 1996. Interest on the outstanding
secured bank loans, equal to the prime rate (9% at June 30, 1995), is payable on
the last day of each month.

10.  SUBSEQUENT EVENTS

MORRISON KNUDSEN CORPORATION OF AUSTRALIA, LTD.:  Effective July 1, 1995, the
Corporation acquired MK Rail's ownership interest in Morrison Knudsen
Corporation of Australia, Ltd. ("MKA") for $3,000 in preferred stock of MKA.

SALE OF WESTERN AIRCRAFT, INC. ("WESTERN"):  On July 21, 1995, the Corporation
sold its ownership interest in Western for $4,900 cash. Since the Corporation's
carrying value of its investment in Western was written down to its estimated
realizable value at December 31, 1994, no gain or loss was recognized upon
closing of the sale transaction.

RETENTION AND SEVERANCE PAY PLANS:  Effective July 7, 1995, the Corporation
adopted a key employee retention and severance program to retain certain key
executives and key employees. The program encourages employees to remain
employed at the Corporation by providing additional compensation from the date
of adoption through July 1, 1996, and by providing enhanced severance benefits
to any covered employee who is involuntarily terminated prior to July 1, 1996.
Under the retention plan, covered employees will receive awards in cash and
stock ranging from 23.3% to 62.5% of their annual base salaries, payable on
December 15, 1995, and July 1, 1996. Under the severance plan, covered employees
who are involuntarily terminated after the occurrence of (i) a change in control
of either the Corporation or the covered employee's division, or (ii) a
bankruptcy filing, will receive cash awards ranging from four to nine months
annual base salary. The severance plan terminates on July 1, 1996, provided that
neither event has occurred. The aggregate amount of the retention plan awards
are estimated to be approximately $12,000, which amount will be accrued ratably
over the service period from July 1995 through June 1996.

NEW AND AMENDED CREDIT FACILITIES:  On August 11, 1995, the Corporation and its
lender banks and sureties agreed to a restructuring of the Corporation's
existing indebtedness.  See Note 7. "Short-Term Debt" for a description of the
restructuring of the Corporation's existing indebtedness, establishment of
interim credit facilities for its Transit segment, issuance of stock purchase
warrants to its lender banks and sureties, and other matters.

ENGINEERING AND CONSTRUCTION:  E&C's revenue for the second quarter of 1995 was
$513.8 million an increase of $14.7 million compared to the same period of 1994.
The increase is principally due to an increase in additional revenue from claim
settlements of $9.5 million.

The E&C segment reported $12.9 million operating income in the second quarter of
1995 compared to an $8.7 million operating loss in the comparable period of
1994. The second quarter 1995 results of operations were affected by the
recognition of certain unusual items consisting of (i) a $9.5 million favorable
impact from the settlement of a number of claims on contracts completed in prior
periods which benefit was partially offset by (ii) the adverse impact of a $2.2
million provision for anticipated costs of settling a long-term real estate
lease obligation.

The second quarter 1994 results of operations were affected by the recognition
of certain unusual items consisting of (i) the adverse impact from the
recognition of a $17.6 million charge to write down investments in two
environmental businesses and fixed assets and provide for an anticipated loss on
a long-term construction project which charge was partially offset by (ii) the
beneficial impact from the recognition of $1.4 million proceeds from a claim
settlement.

TRANSIT: Transit's revenue for the second quarter of 1995 was $120.1 million an
increase of $101.9 million compared to the same period of 1994. The increase was
due to the higher volume of new transit car deliveries for the second quarter
of 1995 as reflected in the table below.

<PAGE>

Transit reported a $2.1 million operating loss in the second quarter of 1995
compared to a $63.1 million operating loss in the comparable period of 1994. The
1995 operating loss stems almost entirely from the recognition of
non-manufacturing  overhead costs and expenses. In 1994 the Transit segment
recognized $198.0 million of pretax charges to operating income for anticipated
cost overruns on fixed-price new transit cars in the early stages of production
which were anticipated to be manufactured and delivered in 1995 and 1996.

In the second quarter of 1994 the Transit segment recognized $59.4 million of
pretax charges to operating income for anticipated cost overruns on fixed-price
new transit cars in the early stages of production which were anticipated to be
manufactured and delivered in 1995 and 1996.

GENERAL AND ADMINISTRATIVE EXPENSES:  General and administrative expenses for
the second quarter of 1995 increased $6.9 million or 84% compared to the same
period of 1994. The increase is due to substantial non-recurring expenses for
legal and other professional fees associated with pending litigation and
financial restructuring offset by allocations of centralized common-service
costs to segment operations.

INTEREST EXPENSE:  Interest expense for the second quarter of 1995 increased
$7.8 million from $1.2 million in the same period of 1994. The significant
increase in interest expense in 1995 is attributed to a substantially higher
level of short-term debt outstanding during the second quarter of 1995 compared
to the comparable period of 1994 and a weighted average cost of borrowing during
the second quarter of 1995 of 10.4% compared to 4.3% during the comparable
period of 1994.

OTHER INCOME (EXPENSE), NET:  Other income of $2.0 million, net for the second
quarter of 1995 is comprised principally of interest earned on short-term
investments. Other expense of $4.3 million, net for the second quarter of 1994
is comprised principally of losses on disposals of assets, write-downs of
certain assets held overseas, and a loan guarantee loss. See Note 8. "Other
Income (Expense), Net".

EQUITY IN NET INCOME (LOSS) OF UNCONSOLIDATED AFFILIATES:  The Corporation's
share of unconsolidated affiliates' income decreased from $4.8 million in the
second quarter of 1994 to $1.7 million in the comparable quarter of 1995. The
decrease is due to the recognition by the Corporation of its $5.6 million equity
in the net income of MIBRAG mbH in the second quarter of 1994. Although MIBRAG
mbH was acquired effective January 1, 1994, the Corporation deferred recognition
of its equity in the net income of MIBRAG mbH for the first quarter of 1994
until certain contingencies existing at March 31, 1994 were resolved in the
second quarter of 1994. See Note 6. "Investments in and Advances to
Unconsolidated Affiliates".

DISPOSITION OF INVESTMENTS IN AFFILIATES:  The $1.3 million loss on disposition
of investments in affiliates for the second quarter of 1995 is the result of
writing-down the increase in the carrying value of its investment in an
affiliate resulting from the Corporation's recognition of affiliate's periodic
income which increase is not expected to be realized through subsequent
disposition of the affiliate. The $13.8 million loss on disposition of
affiliates for the second quarter of 1994 is the result of the Corporation
writing off its investment in Texas TGV Corporation after Texas TGV's failure to
provide equity financing for a high speed rail system project as required under
the franchise agreement. See Note 3. "Disposition of Investments in Affiliates".

INCOME TAX EXPENSES:  The Corporation recognized tax expense for the second
quarter of 1995 of $.9 million consisting only of estimated foreign and state
income taxes relating to certain jurisdictions in which the Corporation had net
taxable income. The Corporation did not provide any tax benefit in 1995 because
management could not predict with reasonable certainty the amount of such
benefit which would be realized from future taxable income. Income taxes
provided in the second quarter of 1994 was based upon an estimated annual
effective tax rate of 40.0% which was slightly lower than the Corporation's
blended statutory tax rate of 40.85% because of anticipated utilization of
foreign tax credits to offset U.S. income taxes.

DISCONTINUED OPERATIONS:  Consistent with the presentation of MK Rail as a
discontinued operation, the Corporation's share of MK Rail's results of
operations for the three month period ended June 30, 1994 and the
Corporation's gain recognized from MK Rail's sale of stock in May 1994, have
been segregated and reported as discontinued operations in the statements of
operations. On May 3, 1994, MK Rail completed an IPO of 6,000,000 shares of
its common stock at an offering price of $16.00 per share which decreased the
Corporation's investment to 65%. The Corporation recognized a $24.0 million
pretax gain with respect to such shares because MK Rail's public offering
price per share exceeded the Corporation's carrying value per share.

ENGINEERING AND CONSTRUCTION: E&C's revenue for the first six months of 1995 was
$929.7 million, a decrease of $25.5 million compared to the same period of 1994
reflecting the decline in new work booked in prior periods.

The E&C segment reported $20.6 million operating income for the first six months
of 1995 compared to $1.8 million operating income in the comparable period of
1994. The results of operations for the first six months of 1995 were affected
by the recognition of certain unusual items consisting of (i) a $12.8 million
favorable impact from the settlement of claims on contracts completed in prior
periods which benefit was partially offset by (ii) the adverse impact of a $2.2
million provision for anticipated costs of settling a long-term real estate

The results of operations for the first six months of 1994 were affected by the

environmental businesses and fixed assets and provide for an anticipated loss on
a long-term project which charge was partially offset by (ii) the benefit from
recognition of $1.4 million proceeds from a claim settlement.

TRANSIT: Transit's revenue for the first six months of 1995 was $221.3 million
an increase of $197.4 million compared to the same period of 1994. The increase
was due to the higher volume of new transit car deliveries for the first six
months of 1995 as reflected in the table below.

</TABLE>

Transit reported a $3.8 million operating loss in the first half of 1995
compared to a $63.9 million operating loss in the comparable period of 1994. The
1995 operating loss stems almost entirely from the recognition of
non-manufacturing overhead costs and expenses.


                                      I-19

<PAGE>

In the first half of 1994 the Transit segment recognized $59.4 million of pretax
charges to operating income for anticipated cost overruns on fixed-price new
transit cars in the early stages of production which were anticipated to be
manufactured and delivered in 1995 and 1996.

GENERAL AND ADMINISTRATIVE EXPENSES: General and administrative expense for the
first half of 1995 increased $8.8 million or 52% compared to the same period of
1994. The increase is due to substantial non-recurring expenses for legal and
other professional fees associated with pending litigation and financial
restructuring offset by allocations of centralized common-services costs to
segment operations.

INTEREST EXPENSE: Interest expense for the first half of 1995 increased $12.6
million from $1.8 million in the same period of 1994. The significant increase
in interest expense in 1995 is attributed to a substantially higher level of
short-term debt outstanding during the first half of 1995 compared to the
comparable period of 1994 and a weighted average cost of borrowing during the
first half of 1995 of 9.4% compared to 4.2% during the comparable period of
1994.

OTHER INCOME (EXPENSE), Net: Other income of $1.7 million, net for the first
half of 1995 is comprised principally of interest earned on short-term
investments. Other expense, net for the first half of 1994 is comprised
principally of losses on disposals of assets, write-downs of certain assets held
overseas, and a loan-guarantee loss, offset by investment gains, underwriting
income and gain from MK Gold's sale of stock. See Note 8. "Other Income
(Expense), Net".

EQUITY IN NET INCOME (LOSS) OF UNCONSOLIDATED AFFILIATES: The Corporation's
share of unconsolidated affiliates' income for the first half of 1995 remained
about the same as reported for the comparable period of 1994 due to the
recognition by the Corporation of its $5.7 million and $5.6 million equity in
the net income of MIBRAG mbH for the first six months of 1995 and 1994,
respectively. See Note 6. "Investments in and Advances to Unconsolidated
Affiliates".

DISPOSITION OF INVESTMENTS IN AFFILIATES: The $8.1 million net loss on
disposition of investments in affiliates for the first half of 1995 consisted of
a pretax gain of $10.0 million in connection with the sale of a McConnell Dowell
subsidiary, offset by a pretax loss of $9.3 million in connection with the
Corporation's sale in June 1995 of its remaining ownership interest in MK Gold
Company and a pretax loss provision of $8.8 million to write-down the carrying
amount of its investment in MK Investments, Inc. (North Pacific construction
operations). The $8.9 million net loss on disposition of investments in
affiliates for the first half of 1994 resulted from a $4.9 million gain on the
Corporation's sale of a portion of its ownership interest in Strait Crossing
Development, Inc. and a $13.8 million loss from writing off the Corporation's
investment in Texas TGV after Texas TGV's failure to provide equity financing
for a high speed rail system project as required under the franchise agreement.
See Note 3. "Disposition of Investments in Affiliates".

INCOME TAX EXPENSES: The Corporation recognized tax expense for the first half
of 1995 of $2.3 million consisting only of estimated foreign and state income
taxes relating to certain jurisdictions in which the Corporation had net taxable
income. The Corporation did not provide any tax benefit in 1995 because
management could not predict with reasonable certainty the amount of such
benefit which would be realized from future taxable income. Income taxes
provided in the first half of 1994 was based upon an estimated annual effective
tax rate of 40.0% which was slightly lower than the Corporation's blended
statutory tax rate of 40.85% because of anticipated utilization of foreign tax
credits to offset U.S. income taxes.

DISCONTINUED OPERATIONS: In connection with its decision to sell MK Rail, the
Corporation recorded a loss from discontinued operations of $31.4 million in
March 1995, without providing any future tax benefit. The loss includes (i) a
$25.5 million write-down of the Corporation's carrying value of its investment
in MK Rail to estimated net realizable value based upon information available in
the circumstances and (ii) an estimated $5.9 million provision for the
Corporation's share of MK Rail's estimated net operating loss until the expected
time of disposal. See Note 2. "Changes in Business - Discontinued Operations".

Consistent with the presentation of MK Rail as a discontinued operation, the
Corporation's share of MK Rail's results of operations for the three and six
month periods ended June 30, 1994 and the Corporation's gain recognized from MK
Rail's sale of stock in May 1994 have been segregated and reported as
discontinued operations in the statements of operations. On May 3, 1994, MK Rail
completed an IPO of 6,000,000 shares of its common stock at an offering price of
$16.00 per share which decreased the Corporation's investment to 65%. The
Corporation recognized a $24.0 million pretax gain with respect to such shares
because MK Rail's public offering price per share exceeded the Corporation's
carrying value per share.

Net cash used for operating activities of $117.4 million in the first half of
1995 included an increase in accounts receivable at June 30, 1995 of $60.0
million. These accounts receivable were sold at December 31, 1994, cancelled
effective March 31, 1995, and subsequently absorbed into the new bank credit
facility on April 11, 1995. In addition, the balance of $57.4 million was
principally used to fund cost overruns on fixed-price contracts, which cost
overruns had been fully reserved in prior periods.

Net cash used for operating activities of $81.3 million in the first half of
1994 was primarily used to fund Transit segment inventories, accounts receivable
and unbilled receivables.

Net cash provided by investing activities in the first half of 1995 of $35.9
million arose principally from (i) $4.3 million net proceeds from sales and
purchases of securities available for sale (ii) $32.5 million proceeds from the
sales of investments in affiliates which included $10.0 million from the sale of
McConnell Dowell's ownership interest in Benjamin Developments, Ltd. and $22.5
million from the sale of the Corporation's ownership interest in MK Gold and
(iii) $1.7 million from collection of outstanding accounts receivables from
affiliates.

Net cash used by investing activities in the first half of 1994 of $15.0 million
resulted from (i) $7.5 million for net acquisitions of property and equipment
and (ii) $7.5 million net investment in and advances to unconsolidated
affiliates. See Note 3. "Disposition of Investments in Affiliates".

Net cash provided by financing activities in the first half of 1995 of $114.9
million included $121.1 million additional borrowings under bank credit
agreements less the payment of the fourth quarter 1994 cash dividend of $6.2
million.

Net cash provided by financing activities in the first half of 1994 of $113.4
million included $132.1 million additional net borrowings under bank credit
agreements less the payment of $19.2 million cash dividends for the three
quarters ended June 1994.

LIQUIDITY

As of August 18, 1995, the Corporation had available cash and credit of $75.9
million for working capital requirements. The Corporation expects significant
negative cash flow from operations during 1995, due primarily to the funding of
the operating losses recognized in 1994, interest cost on bank debt and legal
and professional service fees in connection with the Corporation's legal
proceedings and financial restructuring. Cash has been generated from the sales
of non-core businesses, including MK Gold Corporation which was sold in June
1995 for $22.5 million cash and Western Aircraft, Inc. which was sold in July
1995 for $4.9 million cash. During the second half of 1995, planned sales of
other non-core business units, including MK Rail Corporation, McConnell Dowell
and North Pacific construction operations


                                      I-21

and the investment in AmerBank are, if consummated, expected to generate
significant cash which is required to be used to repay existing indebtedness. No
assurance can be given as to the amount or timing of the proceeds from such
sales.

On April 11, 1995, the Corporation and certain lenders entered into a Credit
Facility ("the Facility") under which the lenders provided secured bridge loans
of $110.0 million and waived conditions of default under its unsecured credit
agreements through May 31, 1995. The Facility established $50.0 million of new
credit capacity and the absorption of an existing $60.0 million accounts
receivable facility. On April 25, 1995 the Facility was amended to include an
additional accounts receivable facility of $12.1 million. The $122.1 million
outstanding under the secured bridge loans was due and payable on May 31, 1995.
On June 14, 1995, a second amendment was signed which extended the maturity date
and waivers to July 31, 1995. Interest on the outstanding balance under the
Facility accrues at the prime rate plus three percent, (12% at June 30, 1995)
and is payable on the last day of each month. Interest on the antecedent bank
debt, equal to the prime rate (9% at June 30, 1995) is generally payable on the
last day of each month. The Corporation repaid $31.2 million of the secured
bridge loans prior to June 30, 1995.

On August 11, 1995, the Corporation, its bank lenders and sureties agreed as
of July 31, 1995 to a restructuring of the Corporation's existing indebtedness
and the establishment of new interim credit facilities, expiring September 1,
1995 to advance funds to the Transit segment prior to its planned divestiture as
a limited liability company, anticipated by September 1, 1995. The restructuring
provides, among other things, for (i) an increase in the amount of the secured
bridge loans from $122.1 million to $129.0 million, (ii) extension of the
maturity date for the secured bridge loans to  March 31, 1996 and extension of
the maturity date for the antecedent bank debt to December 31, 1996, (iii)
mandatory repayment of $100.0 million of antecedent bank debt on September 30,
1996, (iv) required repayments with the net cash proceeds from sales of certain
businesses and assets, and cash collected on certain receivables and (v) the
granting of stock purchase warrants to the lender banks and sureties.

The restructuring provides that ongoing indebtedness of the Corporation to the
banks and its surety syndicate to be secured. In connection with the
restructuring the Corporation would also receive limited bonding capacity.

The Corporation anticipates that the funds available under the restructuring
agreements together with the  net proceeds from planned sales of businesses and
assets currently held for sale and collection of certain receivables should
provide sufficient liquidity until September 30, 1996 when the Corporation
believes, a substantial recapitalization through an equity infusion or new debt
will be required.Unless the Corporation is able to obtain alternative sources of
cash to meet the scheduled repayments at September 30, 1996 and December 31,
1996 required under the restructuring, the Corporation may, among other
alternatives, seek protection from its creditors under the United States
Bankruptcy Code. The Corporation believes that, in such circumstances, the
ability, if any, of its stockholders to recover their investments would be
significantly impaired and that any such recovery, if available, would be
substantially delayed.

PART II. OTHER INFORMATION

ITEM 1.   LEGAL PROCEEDINGS

               The Corporation previously has reported in its Annual Report on
               Form 10-K for the fiscal year ending December 31, 1994, that
               lawsuits in the following four general categories currently are
               pending against the Corporation and its directors and/or
               officers: (1) class actions relating to transactions in the
               common stock of the Corporation ("MK Securities Class Actions");
               (2) class actions relating to the issuance of, and transactions
               in, the common stock of MK Rail ("MK Rail Securities Class
               Actions"); (3) derivative actions brought by persons who claim to
               be stockholders of the Corporation ("Derivative Actions"); and
               (4) claims brought by the former stockholders of Touchstone, Inc.
               ("Touchstone Litigation").

               The MK Securities Class Actions consist of seven separate cases
               which have been consolidated as IN RE: MORRISON KNUDSEN
               SECURITIES LITIGATION, No. 94-0334-S-EJL (U.S. District Court,
               Dist. of Idaho) (first filed July 28, 1994). The defendants
               include the Corporation, certain of the Corporation's current and
               former officers, and the Corporation's auditors. The MK Rail
               Securities Class Actions consist of two cases relating to the
               issuance of, and transactions in, the common stock of MK Rail
               which have been consolidated in the U.S. District Court for the
               District of Idaho. The defendants include the Corporation, MK
               Rail, certain current and former officers and directors of the
               Corporation and MK Rail, and the managing underwriters of MK
               Rail's initial public offering. Those two cases are: SUSSER, ET
               AL. V. AGEE, ET AL., No. CIV 94-0477-S-LMB (U.S. District Court
               for the District of Idaho); and NEWMAN, ET AL. V. AGEE, ET AL.,
               No. CIV 94-0478-S-EJL (U.S. District Court for the District of
               Idaho) (both filed October 20, 1994).

               The Derivative Actions consist of 13 derivative actions which
               have been filed in state courts in Idaho and Delaware , naming as
               defendants certain of the Corporation's President and former
               Directors and Officers. The Corporation is a nominal defendant in
               each of these actions. The five Idaho derivative cases are as
               follows: (i) DEKLOTZ, ET AL. V. MORRISON KNUDSEN CO., ET AL.,
               No. CV-00-9500605D (Idaho District Court, Ada County) (filed

               OF ADMINISTRATION OF FLORIDA V. MORRISON KNUDSEN CORPORATION, ET
               AL., No. CV-OC-9502463D (Idaho District Court, Ada County) (filed
               June 2, 1995) and the eight Delaware derivative cases are as
               follows: (i) STERN V. AGEE, ET AL., Civil Action No. 14032
               (Delaware Chancery Court) (filed February 13, 1995); (ii) HAGER
               V. AGEE, ET AL., Civil Action No. 14034 (Delaware Chancery
               Court) (filed February 14, 1995); (iii) TROY V. AGEE, ET AL.,
               Civil Action No. 14167 (Delaware Chancery Court) (filed March 31,
               1995); (iv) CAFFREY V. AGEE, ET AL., Civil Action No. 14033
               (Delaware Chancery Court) (filed February 13, 1995); (v)
               HAMMERSLOUGH V. AGEE, ET AL., Civil Action No. 14042 (Delaware
               Chancery Court) (filed February 17, 1995); (vi) ROSENN V. AGEE,
               ET AL., Civil Action No. 14106 (Delaware Chancery Court) (filed
               March 9, 1995); (vii) CITRON V. AGEE, ET AL., Civil Action No.
               14136 (Delaware Chancery Court) (filed March 22, 1995); and
               (viii) ANTONICELLO V. AGEE, ET AL., Civil Action No. 14182
               (Delaware Chancery Court) (filed April 4, 1995).

               The Touchstone Litigation consists of two cases brought by the
               former stockholders of Touchstone which currently are pending in
               U.S. District Court in Tennessee: THEODORE E. NELSON V. MORRISON
               KNUDSEN CORP., No. 95-1029 (U.S.D.C. W.D. Tenn.) (filed February
               7, 1995); and RICHARD JACOBS, ET AL. V. MORRISON KNUDSEN CORP.,
               No. 95-1024 (U.S.D.C. W.D. Tenn.) (filed February 7, 1995). The
               plaintiffs, who among other things purport to state claims for
               violation of federal and Tennessee securities laws, purport to be
               all of the stockholders of Touchstone prior to the Corporation's
               acquisition of Touchstone through an exchange offer. The
               Corporation is the sole defendant in these two cases. The
               Corporation has been advised that the plaintiffs have filed a
               separate lawsuit against William J. Agee, the Corporation's
               former chairman: RICHARD L. JACOBS, ET AL. V. WILLIAM J. AGEE,
               No. 95-1168 (U.S.D.C. W.D. Tenn.) (filed July 18, 1995). The
               Corporation further has been advised that the complaint naming
               Mr. Agee, which contains allegations similar to those against the
               Corporation, has not been served and that such case currently
               remains inactive.

               As has been previously reported, settlement discussions have been
               held among the Corporation, MK Rail, certain of their present and
               former officers and directors, their insurance carriers, the
               underwriter defendants, and plaintiffs, and that those
               discussions have resulted in agreements as to the principal terms
               of settlement of the MK Securities Class Actions, the MK Rail
               Securities Class Actions and the Derivative Actions (other than
               the FLORIDA case pending in Idaho) as to all defendants in those
               cases other than the Corporation's auditors. Discussions are
               continuing between certain of the plaintiffs and defendants with
               respect to the final terms of the memoranda of understanding with
               respect to the settlements. Once the final terms have been agreed
               to, it is anticipated that the parties will enter into formal
               settlement documentation; the settlements then will be submitted
               for and be subject to approval by the appropriate courts.

               The settlement terms will require the Corporation, as its share
               of the settlement; to (i) issue 2,976,923 shares of Common Stock
               in connection with the settlement of the MK Securities Class
               Actions, (ii) issue 869,231 shares of Common Stock in connection
               with the settlement of the MK Rail Securities Class Actions,
               (iii) pay the net (after plaintiffs attorneys fees and related
               expenses) insurance proceeds received by the Corporation in
               connection with the settlement of the Derivative Actions into a
               settlement fund to be created in connection with the settlement
               of the MK Securities Class Actions, and (iv) implement certain
               corporate governance procedures (including, among other things,
               making reasonable efforts to appoint up to seven additional
               non-employee directors, a presumption that Board and Stockholders
               meetings will be held in Boise or certain other specified
               locations, disclosure of certain common memberships of directors
               or their immediate families on governing bodies of not-for-profit
               organizations, and a requirement that future executive
               compensation not be based on non-recurring items without
               stockholder approval). In addition, the defendant non-employee
               directors (other than Mrs. Peden) would relinquish five years of
               credited service for purposes of the Corporation's Retirement
               Plan for Non-Employee Directors. The settlement terms also would
               require MK Rail, as its share of the settlement of the MK Rail
               Securities Class Actions, to issue 413,793 shares of Common Stock
               and shares of a new class of Preferred Stock with a redemption
               value of $1 million. The Corporation's insurance carriers will
               pay $35 million (including the amounts referred to in clause
               (iii) above) on behalf of the individual defendants in the MK
               Securities Class Actions and the Derivative Actions, and MK
               Rail's insurance carrier will pay $6 million into a settlement
               fund to be created in connection with the settlement of the MK
               Rail Securities Class Actions, such payments to be made with
               respect to the individual defendants in those cases. The funds
               paid by MK Rail's insurance carrier will include the purchase
               from the settlement fund of the MK Rail Preferred Stock referred
               to above for $1 million. As part of the proposed settlement of
               the Derivative Actions, Mr. Agee would relinquish his claim to
               contractual severance pay and all other contractual benefits
               other than his Supplemental Savings Plan account (approximately
               $350,000 as of April 20, 1995, the date the Plan was terminated),
               a reduced lifetime (with right of survivorship) annual
               supplemental retirement benefit of $99,750 commencing in 1995,
               and prepaid medical and dental benefits for Mr. Agee and his
               family.

               In connection with the agreements as to the principal terms of
               settlement of the MK Securities Class Actions, the MK Rail
               Securities Class Actions, and the Derivative Actions (other than
               the FLORIDA case pending in Idaho), the Corporation and MK Rail
               accrued a total estimated liability of $29 million at December
               31, 1994. However, there can be no assurance that all the parties
               to these agreements will agree on the terms of the final
               settlement or that such final settlement will be approved by the
               appropriate courts.

               The Corporation has been advised that it may become
               subject to an ongoing investigation by the Central Regional
               Office of the Securities and Exchange Commission of the issuance
               by the City and County of Denver of revenue bonds to finance the
               construction of the new Denver International Airport. A
               subsidiary of the Corporation is a joint venture partner of The
               Greiner/MKE Team, which was the program management support
               consultant in connection with the construction of the new
               airport.

such amount is made available to the Borrowers until the date such amount is
repaid to the Administrative Agent, at (i) in the case of the Borrowers, a rate
per annum equal to the Prime Rate plus three percent (3%), and (ii) in the case
of such Lender, the Federal Funds Rate.  If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Lender's Loan included in such Borrowing for purposes of this
Agreement.

                (a)   The Loans of each Lender to the Borrowers shall be

in an original principal amount equal to such Lender's Commitment.

                (b)   Upon receipt of each Lender's Note pursuant to SECTION
5.1(b), the Administrative Agent shall forward such Note to such Lender.  Each
Lender shall record the date, amount and maturity of each Loan made by it to the
Borrowers and the date and amount of each payment of principal made by the
Borrowers with respect thereto, and may, if such Lender so elects in connection
with any transfer or enforcement of its Note, endorse on the schedule forming a
part thereof appropriate notations to evidence the foregoing information with
respect to each such Loan then outstanding; PROVIDED, that the failure of any
Lender to


                                        22
<PAGE>



make any such recordation or endorsement shall not affect the obligations of
either Borrower hereunder or under the Notes absent manifest error.  Each Lender
is hereby irrevocably authorized by each Borrower so to endorse its Note and to
attach to and make a part of any Note a continuation of any such schedule as and
when required.

      2.5.      MATURITY OF LOANS.  Each Loan included in any Borrowing shall
mature, and the principal amount thereof shall be due and payable, on the
Termination Date.

      2.6.      INTEREST RATES.

                (a)   Except as provided in SECTION 2.6(b), each Loan shall
bear interest on the outstanding principal amount thereof, for each day from the
date such Loan is made until it becomes due, at a rate per annum equal to the
Prime Rate for such day plus three percent (3%).  Interest shall be payable each
calendar month on the last day of such month and on the Termination Date.

                (b)   Any overdue principal of or interest on any Loan 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 by the Administrative Agent in accordance with the terms of
this Agreement, interest shall accrue on the Obligations at the Default Rate and
is payable on demand.  Any interest, reasonable professional fees and expenses
of the Administrative Agent, the Co-Agents and the Collateral Agent, or other
reasonable professional fees, expenses and charges of the Steering Committee
Lenders due under SECTION 13.4, which are not paid as and when due, shall bear
interest at the Default Rate.  The interest rate increase shall take effect

Borrowers.

                (a)   CLOSING FEE.  The Borrowers shall pay to the
Administrative Agent for the benefit of the Lenders, on the Closing Date, a

Fee").  The Bank of America Fee is payable from the Closing Date until such time
as the Borrowers and the Co-Agents have no Obligations under this Agreement and
the other Loan Documents and the obligation to pay the Bank of America Fee shall

of the Obligations under this Agreement.

                (e)   FEES CUMULATIVE.  All fees payable under this Agreement
shall be cumulative, and fully earned on the date of payment.

time, or from time to time in part in amounts aggregating $1,000,000 or any
larger multiple of $1,000,000, by paying the principal amount to be prepaid
together with accrued interest thereon to the date of prepayment.  Each such
optional prepayment shall be applied to prepay each Lender's Loans in an amount
equal to such Lender's Applicable Pro Rata Share of such prepayment.

                (b)   Upon receipt of a notice of prepayment pursuant to this
Section, the Administrative Agent shall promptly notify each Lender of the
contents thereof and of such Lender's Applicable Pro Rata Share of such

immediately pay to the Administrative Agent for the benefit of such Lender, the
amount necessary to reduce the aggregate principal amount of such Loans to the

    2.10.     APPLICATION OF PAYMENTS.  All payments (including
prepayments), other than regularly scheduled interest payments, on the Loans or
on any of the other Obligations (other than Obligations under the Cash
Management System) shall be made to the Administrative Agent for application

treat such payments for purposes of its own accounting):  FIRST to then due
and outstanding fees, expenses or other charges of the Administrative Agent, the
Co-Agents, the Steering Committee Lenders or the Collateral Agent under this
Agreement or any of the other Loan Documents to the extent payable by the
Borrowers or the Guarantors; SECOND to then due interest on the Loans accrued
and unpaid prior to the date such funds are received by the Lenders; and THIRD
to the principal balance of the Loans (as provided in SECTION 12.2).

      2.11.     GENERAL PROVISIONS AS TO PAYMENTS.  The Borrowers shall make
each payment of principal of, and interest on, the Loans and of fees and of all

<PAGE>



such payment received by the Administrative Agent for the account of the
Lenders.  The Borrowers agree to pay to the Administrative Agent, upon demand,
the amount of any payment received by the Administrative 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 Administrative Agent's demand
therefor, then each Lender shall pay to the Administrative Agent the share of
such returned payment received by it.  Upon receipt by the Administrative Agent
of any such payment from the Borrowers, or from the Lenders in the event the
Borrowers fail to make such payment after the Administrative Agent's demand, the
Administrative 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 Loans shall be
reinstated to the extent the Administrative Agent makes such payment.  Whenever
any payment of principal of, or interest on, the Loans or of fees with respect
to the Loans or of any other 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.

      2.12.     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).

      2.13.     CASH MANAGEMENT SYSTEM.  Each Borrower will establish, on or
prior to the Closing Date, and each Borrower will maintain until the Obligations
have been paid in full and all Commitments have been terminated, the Cash
Management System described in SCHEDULE F.


                                  ARTICLE III

                           CHANGE IN CIRCUMSTANCES

      3.1.      INCREASED COST.

                (a)   If any Lender shall have determined that, after the date
hereof, the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or


                                        27
<PAGE>



administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on capital of such Lender (or its Parent)
as a consequence of such Lender's obligations hereunder to a level below that
which such Lender (or its Parent) could have achieved but for such adoption,
change, request or directive (taking into consideration its policies with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time, within 15 days after demand by such Lender (with a copy
to the Administrative Agent), the Borrowers shall pay to such Lender such
additional amount or amounts as will compensate such Lender (or its Parent) for
such reduction.

                (b)   Each Lender will promptly notify the Borrowers and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Lender to compensation pursuant to this
SECTION 3.1.  A certificate of any Lender claiming compensation under this
SECTION 3.1 and setting forth the additional amount or amounts to be paid to
it hereunder shall be conclusive in the absence of manifest error.  In
determining such amount, such Lender may use any reasonable averaging and
attribution methods.

      3.2.      TAXES.

                (a)   Any and all payments by either Borrower to or for the
account of any Lender or the Agents hereunder or under any Note 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 3.2) such Lender or
the Agents (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 Administrative 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 Lender and each
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 3.2) paid by such Lender or the Agents (as the case may be) and any
liability


                                        28
<PAGE>



(including penalties, interest and expenses) arising therefrom or with respect
thereto.  This indemnification shall be paid within 15 days after such Lender or
the Agents (as the case may be) makes demand therefor.

                (c)   Each 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 Lender listed on the signature pages
hereof and on or prior to the date on which it becomes a Lender in the case of
each other Lender, and from time to time thereafter if requested in writing by
the Borrowers (but only so long as such 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 Lender is entitled to benefits under an income tax treaty
to which the United States is a party which exempts the Lender from United
States withholding tax or reduces the rate of withholding tax on payments of
interest for the account of such 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 a Lender has failed
to provide the Borrowers with the appropriate form pursuant to SECTION 3.2(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 to be
provided), such Lender shall not be entitled to indemnification under SECTION
3.2(b) or (c) with respect to Taxes imposed by the United States on payments
by such Borrower; PROVIDED, that if a 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 Lender shall reasonably request to assist such Lender to
recover such Taxes.

                (e)   If either Borrower is required to pay additional amounts
to or for the account of any Lender pursuant to this SECTION 3.2, then such
Lender will change the jurisdiction of its lending office to an office it
maintains if, in the judgment of such Lender, such change (i) will eliminate or
reduce any such additional payment which may thereafter accrue and (ii) is not
otherwise disadvantageous to such Lender.

Agreement, and to make the Loans and other financial accommodations provided for
herein, the Borrowers hereby make the following representations and warranties

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

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 and each of the other Restructuring 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 will
constitute, legal and valid obligations of each Borrower binding upon it and

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 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

financing transactions contemplated hereby or with the execution, delivery,
performance, validity or enforceability of this Agreement or the other
Restructuring 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

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.

Material Adverse Effect, or could reasonably be expected to affect the
Borrowers' or the Guarantors' ability to perform their Obligations under this
Agreement, the Notes and the other Restructuring 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
Administrative Agent a true and complete copy of each Material Contract required
to be listed on SCHEDULE 6.8.

      6.9.      CORRECTNESS OF COLLATERAL SCHEDULES.  The Certification of

the Borrowers and their Consolidated


                                        37
<PAGE>



Subsidiaries of the results of operations and other information projected

assets described in the Security Documents capable of being perfected by the
filing of a Financing Statement, subject only to Permitted Liens.

      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

or any of their properties, income or franchises, including interest,

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,


                                        38
<PAGE>



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 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 Administrative 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,


                                        39
<PAGE>



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
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Materials, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses).  On the
basis of this review, the Borrowers have reasonably concluded that such
associated liabilities and costs, including the costs of compliance with
Environmental Laws, are unlikely to have or result in a Material Adverse Effect.

      6.19.     NO MATERIAL ADVERSE EFFECT.  Since June 26, 1995, there has
been no Material Adverse Effect, other than as disclosed in SCHEDULE 6.19.

      6.20.     CONSOLIDATED SUBSIDIARIES; SUBSIDIARIES.  Each of the

other entity duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization, and has all legal powers and all
material governmental licenses, authorizations, consents and approvals required
to carry on its business as now conducted.  Set forth on SCHEDULE 6.20 is a
complete and correct list of each of the Borrower's Subsidiaries.  Set forth on
SCHEDULE E is a complete and correct list of each of the Borrower's
wholly-owned Subsidiaries other than foreign wholly-owned subsidiaries, Emkay
Development Company, Inc. and Emkay Capital Investments, Inc.

      6.21.     MARGIN SECURITIES.  Neither Borrower nor any Guarantor is
engaged principally in, nor has as one of its most important activities, the
business of extending credit for the purpose of purchasing or carrying "margin
stock" as that term is defined in Regulation U promulgated by the Board of
Governors of the Federal Reserve System, as now in effect.  No part of the


                                        40
<PAGE>



Indebtedness evidenced by the Notes, or Indebtedness otherwise created in
connection with this Agreement or the other Restructuring Documents, shall be
used, directly or indirectly, for the purpose of purchasing any such margin
stock.  If requested by the Administrative Agent, the Borrowers shall furnish or
cause to be furnished to the Administrative Agent a statement, in conformity
with the requirements of Federal Reserve Form U-1 referred to in Regulation U,
to the foregoing effect.

      6.22.     INVESTMENT COMPANY ACT.  Neither of the Borrowers nor any
Guarantor is an "investment company" nor a company "controlled" by an investment
company within the meaning of the Investment Company Act of 1940, as now in
effect.

      6.23.     BUSINESS LOCATIONS AND TRADE NAMES.  Set forth on SCHEDULE
6.23A is a complete and correct list of each location where each of the

records.  Set forth on SCHEDULE 6.23B is a complete and correct list of each
name under or by which each Borrower and Guarantor conducts its business, or by
which each Borrower and Guarantor (or its predecessors in interest) has
conducted its business during the past five years.

      6.24.     TITLE TO REAL PROPERTY AND OTHER ASSETS.  The Borrowers and
the Guarantors have good and marketable title (or good and marketable leasehold
interests with respect to leased property) to all their Real Property and all
personal property assets and fixtures subject to no Liens other than Permitted
Liens.  The Borrowers and the Guarantors hold directly the fee and leasehold
interest in all facilities constituting the Real Property Collateral.  As of the
Closing Date, there are no contracts or options by either Borrower, any
Guarantor or any of their Subsidiaries for the sale or lease of any of the Real
Property Collateral, except as set forth on SCHEDULE 6.24.  All easements,
servitudes and rights of way necessary to the operations presently conducted or
proposed to be conducted at the facilities constituting the Real Property
Collateral have been obtained.

      6.25.     LABOR MATTERS.  There are no controversies pending between the
Borrowers, the Guarantors or their Subsidiaries and their employees which may
constitute or result in a Material Adverse Effect.

6.26 is a complete and accurate list of (i) all employment agreements and
executive compensation arrangements to which any Borrower, any Guarantor or any
Subsidiary of a Borrower or a Guarantor is a party which provides for aggregate
compensation to any Person (assuming compliance with or

satisfaction of all contingencies or conditions) of more than $150,000 per year,
and (ii) all agreements relating to the voting or disposition of any outstanding
shares of capital stock of each Borrower, Guarantor or any of their
Subsidiaries.  The Borrowers and the Guarantors have delivered to the
Administrative Agent a true and complete copy of each of the agreements required
to be listed in SCHEDULE 6.26.

      6.27.     NO MISSTATEMENTS.  Neither this Agreement, the Notes, the
other Restructuring Documents, nor any document, instrument and other agreement,
certificate, statement or other information referred to herein or expressly
furnished to the Administrative Agent or to any of the Lenders pursuant hereto
or thereto, contains any misstatement of a material fact or omits to state any
material fact or any fact necessary to make the statements contained herein or
therein not misleading on the date furnished or on the Closing Date, except as
otherwise subsequently disclosed to the Administrative Agent and all Lenders in
writing on or prior to the Closing Date.

      6.28.     RESTRUCTURING.  The Restructuring has occurred.

      6.29.     MK RAIL LOCK BOX.  Lock Box number 98485 maintained at

not collections related to any Borrower or any Guarantor.  No Borrower or

such Borrower or such Guarantor to make any payment to Lock Box number 98485.

      6.30.     CASH MANAGEMENT SYSTEM.  Each Borrower acknowledges that the
Cash Management System is part of this Agreement and each of the representations

without expiration of any period of grace (other than that specifically provided
herein), may enforce payment of all Obligations of any Borrower to the
Administrative Agent and the Lenders and the Administrative Agent shall be
entitled to all remedies available hereunder and thereunder.

      9.3.      OTHER REMEDIES.   Subject to the Intercreditor Agreements,
upon the occurrence of an Event of Default or at any time thereafter, after

in relying, (x) upon any writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document, instrument or conversation believed by it to
be genuine and correct and to have been signed, sent or made by the proper
Person or Persons, or (y) upon advice and statements of legal counsel,
independent accountants and other experts selected by the Administrative Agent
and each Co-Agent.  The Administrative Agent and each Co-Agent may deem and
treat each Lender party hereto or any Assignee as a Lender for all purposes
unless a written notice of the assignment, negotiation or transfer thereof, in
accordance with the provisions of this Agreement shall have been delivered to
the Administrative Agent or Co-Agents identifying the name of any successor or

future holders of the Notes.

shall not be deemed to have knowledge or notice of the occurrence of any Event
of Default unless the Administrative Agent and each Co-Agent has received notice
from a Lender or the Borrowers referring to this Agreement, describing such

Administrative Agent or Co-Agents receives such a notice or has actual knowledge
of the occurrence of an Event of Default,


                                        62
<PAGE>



the Administrative Agent or Co-Agents promptly shall give notice thereof to the
Lenders.  The Administrative Agent and Co-Agents shall take such action with
respect to such Event of Default as shall be directed by the Majority Lenders;
PROVIDED, HOWEVER, that unless and until the Administrative Agent and each
Co-Agent shall have received such directions, the Administrative Agent and each
Co-Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Event of Default as it deems advisable
in the best interests of the Lenders.

      10.8.     NON-RELIANCE ON THE ADMINISTRATIVE AGENT, CO-AGENTS AND THE
Other Lenders.  Each Lender expressly acknowledges that neither the
Administrative Agent, Co-Agents nor any of their officers, directors, employees,
agents, attorneys-in-fact or affiliates has made any representations or
warranties to it.  The Administrative Agent and each Co-Agent shall have no
obligation or liability to any of the Lenders regarding the creditworthiness or
financial condition of any Borrower.  No act by the Administrative Agent or
Co-Agents hereinafter taken, including any review of the Borrowers, shall be
deemed to constitute any representation or warranty by the Administrative Agent
or Co-Agents to any Lender.  Each Lender represents to the Administrative Agent
and each Co-Agent that, independently and without reliance upon the
Administrative Agent or Co-Agents or any other 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 make its Loans hereunder and to enter into this Agreement.
Each Lender also represents that, independently and without reliance upon the
Administrative Agent or Co-Agents or any other 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 Lenders by the Administrative Agent or Co-Agents
hereunder, the Administrative Agent and Co-Agents shall have no obligation or
liability to provide any 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 Administrative Agent, the Co-Agents or any of their officers, directors,
employees, agents, attorneys-in-fact or affiliates.

      10.9.     COLLATERAL.  Each of the Lenders represents to the
Administrative Agent, each Co-Agent and each of the other Lenders


                                        63
<PAGE>



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 Lenders shall indemnify, defend
and hold harmless the Administrative Agent and each Co-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 Equalization
Pro Rata Share as of date demand for payment is made 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 Administrative
Agent or any Co-Agent in their capacity as such and not in their 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 Administrative Agent or any Co-Agent under
or in connection with any of the foregoing; PROVIDED, HOWEVER, that no
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 Administrative Agent's or any Co-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.    EACH AGENT IN ITS INDIVIDUAL CAPACITY.  Each of the Agents 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 such Agent was not
an Agent hereunder.  With respect to its Existing Indebtedness and any other
Loans made or renewed by it, such Agent in its individual capacity shall have
the same benefits, rights, powers and privileges under this Agreement, and the
Loan Documents as any Lender and may exercise the same as though it were not an
Agent, and the terms "Lender" and "Lenders" shall include such Agent in its
individual capacity.

      10.12.    SUCCESSOR ADMINISTRATIVE AGENT AND CO-AGENT.  The
Administrative Agent and each Co-Agent may resign as such upon ten days' prior
written notice to the Lenders.  The


                                        64
<PAGE>



Administrative Agent and each Co-Agent shall concurrently provide the Borrowers
with a copy of such notice.  If the Administrative Agent or either Co-Agent
shall resign as such under this Agreement, then the Majority Lenders shall
appoint from among the Lenders a successor agent for the Lenders.  A successor
agent may also be appointed by the Majority Lenders if the Administrative Agent
or either Co-Agent ceases to have any Loans hereunder, and upon such appointment
of a successor agent the Administrative Agent or Co-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 Administrative Agent or Co-Agent, as the case may be, (b) the retiring
Administrative Agent or Co-Agent shall be discharged of all its obligations and
liabilities in such capacity under this Agreement, and the Loan Documents, (c)
the term "Administrative Agent" and "Co-Agents" shall mean such successor agent
effective upon its appointment, and (d) the retiring Administrative Agent's or
Co-Agent's rights, powers and duties as the Administrative Agent or Co-Agent as
the case may be shall be terminated, without any other or further act or deed on
the part of such former Administrative Agent or Co-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 Administrative Agent or Co-Agent
while it was the Administrative Agent or Co-Agent (for which retiring
Administrative Agent or Co-Agent may still have liability), the retiring
Administrative Agent or Co-Agent shall continue to receive the benefits of this
ARTICLE X, including SECTION 10.10.

      10.13.    APPLICABILITY OF SECTION TO THE BORROWERS.  Notwithstanding

                                  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 otherwise,
will be paid strictly in accordance with the terms of this Agreement and the
other Loan 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
Administrative Agent or the 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 Administrative Agent or any 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,
any Note, the other Restructuring Documents or by operation of law or otherwise;

                (b)   Any modification or amendment of or supplement to this
Agreement, any Note 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, any Note 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, any Note 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 Administrative
Agent, any 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, any Note 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 of or
interest on any Note 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 Administrative Agent, any 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, any Note 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 Commitments shall have terminated and the principal of and
interest on the Notes and all other amounts payable by the Borrowers under this
Agreement shall have been paid in full.  If at any time any payment of the
principal of or interest on any Note 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
ADMINISTRATIVE AGENT, THE CO-AGENTS, THE COLLATERAL


                                        67
<PAGE>



AGENT OR ANY 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 THE OBLIGATIONS BEFORE
SEEKING FROM SUCH BORROWER PAYMENT IN FULL OF ITS OBLIGATIONS TO THE
ADMINISTRATIVE AGENT AND THE 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 ADMINISTRATIVE AGENT AND THE 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 ADMINISTRATIVE 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 ADMINISTRATIVE
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
ADMINISTRATIVE 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
ADMINISTRATIVE 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 LENDERS, EVEN THOUGH THAT
ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH RESPECT TO SECURITY
FOR A GUARANTEED


                                        68
<PAGE>



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 ADMINISTRATIVE
AGENT AND THE LENDERS FOR ANY OBLIGATIONS EVEN IF THE ADMINISTRATIVE AGENT SELLS
AN INTEREST IN REAL PROPERTY BY JUDICIAL FORECLOSURE ACTION AND SUCH BORROWER'S
RIGHTS AGAINST THE BORROWERS ARE LIMITED BY THE OPERATION OF CCP SECTIONS 580b
OR 580d OR SIMILAR LAWS; AND

                (c)   SUCH BORROWER AGREES THAT THE ADMINISTRATIVE AGENT AND THE
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 ADMINISTRATIVE AGENT'S OR ANY 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 ADMINISTRATIVE AGENT'S, THE CO-AGENTS' AND EACH
LENDER'S ENTERING INTO THIS AGREEMENT AND THAT THE ADMINISTRATIVE AGENT, THE
CO-AGENTS AND EACH 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
or its Notes 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 Administrative Agent made at the request of the
Majority Lenders.

                                  ARTICLE XII

              TREATMENT OF LENDER'S APPLICABLE PRO RATA SHARES

      12.1.     FUNDING OF LOANS.

                (a)   Prior to the Equalization Date, each Lender's Applicable
Pro Rata Share of each Alpha Loan shall be such Lender's Alpha Pro Rata Share
and such Lender's Applicable Pro Rata Share of each Beta Loan shall be such
Lender's Beta Pro Rata Share.  Each Lender acknowledges and agrees that until
the Equalization Date: (i) any Borrowing which would cause the aggregate amount
of all Loans to increase from an amount below $69,198,468 to an amount less than
the Equalization Date Loan Amount will consist of Alpha Loans to the extent of
the portion which would cause the aggregate amount of all Loans to equal
$69,198,468 and Beta Loans to the extent of the portion of the Borrowing which
would cause the aggregate amount of all Loans to exceed $69,198,468 but be less
than the Equalization Date Loan Amount and (ii) each Lender's share of any
Borrowing which would cause the aggregate amount of all Loans to exceed the
Equalization Date Loan Amount shall be the amount necessary such that
immediately after such Borrowing, each Lender's Outstanding Pro Rata Share shall
be equal to such Lender's Equalization Pro Rata Share.

                (b)   After the Equalization Date each Lender's Applicable Pro
Rata Share of the Loans shall be such Lender's Equalization Pro Rata Share.

      12.2.     PREPAYMENTS AND REPAYMENTS OF LOANS.

                Prepayments and repayments to be applied to the principal
balance of the Loans shall be distributed by the Administrative Agent pursuant
to the requirements of SECTION 2.10 and SECTION 2.11 to the Lenders as
follows:

                (i) until the Equalization Date, to the Lenders, each in
accordance with its Outstanding Pro Rata Share and (ii) on or after the
Equalization Date, to the Lenders, each in accordance with its Equalization Pro
Rata Share; PROVIDED that from and after acceleration of the Obligations: (a)
until the Equalization Date, payments (including receipt of proceeds of
Collateral) shall be based upon each Lender's Alpha Pro Rata Share but only to
the extent that, after giving effect to any such payment, the outstanding
balance of the Loans does not equal or exceed the Equalization Date Loan Amount
and (b) on or after the Equalization Date after giving effect to the payments
described in clause (a) above, payments (including receipt of proceeds of
Collateral) shall be based upon each Lender's Equalization Pro Rata Share.



                                        70
<PAGE>



      12.3.     TREATMENT OF MAXIMUM LOAN AMOUNTS AND COMMITMENTS.  Reductions
of each Lender's Maximum Loan Amount and Commitments pursuant to SECTION 2.9
shall be applied to each Lender's Maximum Loan Amount and Commitments based upon
such Lender's Equalization Pro Rata Share.

      12.4.     TREATMENT OF LOANS FOR VOTING PURPOSES.  Any vote, consent or
other action to be taken by the Majority Lenders under the Loan Documents shall
be calculated based on each Lender's Equalization Pro Rata Share.  Any vote,
consent or other action to be taken by All Lenders shall require the vote,
consent or other action of each of the Lenders.

      12.5.     EQUALIZATION OF APPLICABLE PRO RATA SHARES.  On each date
prior to the Equalization Date upon which any Borrowings occur or payments or
prepayments on account of Loans are received by the Administrative Agent, and on
the Equalization Date, the Administrative Agent shall calculate the amount of
each Lender's Outstanding Pro Rata Share.  In the event that the Equalization
Date shall have occurred for any reason other than clause (iv) of the definition
of "Equalization Date", then each Purchasing Lender shall purchase an assignment
in such portion of all Selling Lenders' Loans, for a purchase price in each case
equal to the outstanding principal amount of each such portion as shall cause
such Purchasing Lender's Outstanding Pro Rata Share to equal its Equalization
Pro Rata Share.  Each Purchasing Lender shall satisfy its obligation under this
Section 12.5 by paying to the Administrative Agent on such Equalization Date an
amount equal to the aggregate amount due from it to all Selling Lenders in
immediately available funds no later than 1:00 p.m., (Pittsburgh, Pennsylvania
time).  Administrative Agent shall distribute to each Selling Lender on such
date amounts due to such Selling Lender from funds paid to the Administrative
Agent by each Purchasing Lender in immediately available funds no later than
3:00 p.m. (Pittsburgh, Pennsylvania time).  In the event any Purchasing Lender
fails to honor its purchase obligation under this Section 12.5, Administrative
Agent shall pay sums otherwise payable to such Purchasing Lender under Section
12.2 pro rata to each Selling Lender until such Purchasing Lender's Outstanding
Pro Rata Share of all Loans equals its Equalization Pro Rata Share for all
Loans.

      12.6.     ADMINISTRATIVE AGENT'S CALCULATION OF APPLICABLE PRO RATA
SHARES.  The Administrative Agent's calculation of each Lender's Applicable Pro
Rata Share shall be binding upon each Lender absent manifest error.

                                 ARTICLE XIII

                                MISCELLANEOUS

      13.1.     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 Administrative Agent and the 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 Administrative Agent under ARTICLE II or
ARTICLE III shall not be effective until received.

      13.2.     ENTIRE AGREEMENT.  The execution and delivery of this
Agreement, the Notes 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, the Notes 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.

      13.3.     NO WAIVERS.  No failure or delay by the Administrative Agent
or any Lender in exercising any right, power or privilege hereunder or under any
Note or 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.

      13.4.     EXPENSES; INDEMNIFICATION.

                (a)   The Borrowers shall pay (i) all reasonable out-of-pocket
expenses of the Administrative Agent, the Co-Agents and the Steering Committee
Lenders as a group, as such group is constituted on the Closing Date (as set
forth in the attached SCHEDULE 13.4) 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


                                        72
<PAGE>



hereof or any Default or alleged Default hereunder, (ii) if an Event of Default
occurs, all reasonable out-of-pocket expenses incurred by the Administrative
Agent, the Co-Agents 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 Lender accruing from and after the Termination Date in connection with
payment of the Obligations.

                (b)   The Borrowers agree to indemnify the Administrative Agent,
the Co-Agents and each Lender, their respective Affiliates and the respective
directors, officers, agents and employees of the foregoing (each an
"Indemnitee") and hold each Indemnitee harmless from and against any and all
liabilities, losses, damages, costs and expenses of any kind, including 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 Loans hereunder or (ii) directly or indirectly resulting from,
arising out of, or is 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 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.

      13.5.     SET-OFF; SHARING OF SET-OFFS.

                (a)   In addition to any rights and remedies of the Lenders
provided by law, the 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 Lender which security interest shall secure the
Obligations.  Upon the occurrence and during the continuance of


                                        73
<PAGE>



an Event of Default, provided that it has first received the written consent of
the Administrative 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 Lender may set off and apply against any Obligations,
whether matured or unmatured, of the Borrowers to the Lenders, any amount owing
from the Lenders to the Borrowers.  No 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 Administrative Agent.  Each
Lender promptly shall notify the Borrowers and the Administrative Agent after
any such setoff and application made by any such 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 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
Loan Documents.  Any such set-off rights will be subject to the Intercreditor
Agreements.

                (b)   Each Lender agrees that if it shall, by exercising any
right of set-off or counterclaim or otherwise, receive payment of a proportion
of the aggregate amount of principal and interest due to it which is greater
than the proportion received by any other Lender in respect of the aggregate
amount of principal and interest due to such other Lender, the Lender receiving
such proportionately greater payment shall purchase such participations in the
Loans held by the other Lenders, and such other adjustments shall be made, as
may be required so that all such payments of principal and interest with respect
to the Loans held by the Lenders shall be shared by the Lenders pro rata;
PROVIDED, that nothing in this Section shall impair the right of any Lender 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 Indebtedness of a Borrower
other than its Indebtedness hereunder.  Each Borrower agrees, to the fullest
extent it may effectively do so under applicable law, that any holder of a
participation in a Loan, whether or not acquired pursuant to the foregoing
arrangements, may exercise 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.

      13.6.     AMENDMENTS AND WAIVERS.  Any provision of this Agreement, the
Notes or the other Loan Documents may be amended or waived if, but only if, such
amendment or waiver is in writing and is signed by the Borrowers, the
Administrative Agent, the Co-


                                       74

<PAGE>



Agents and the Majority Lenders; PROVIDED, that
(i) the consent of All 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 Loans, (b) a change in the rate of interest or fees
to be paid by the Borrowers with respect to any of the Loans, (c) a change in
the definitions of "All Lenders", "Majority Lenders", "Applicable Pro Rata
Share" or the definitions referred to therein, (d) any increase in the total
amounts of the Commitments or in any Lender's Maximum Loan Amount or Commitment
or any change that subjects any Lender to any additional obligation, (e) this
SECTION 13.6 or ARTICLE XII, (f) the release of any Guarantor or any
Borrower, (g) any change in lien priorities created by, or other material terms
of, the Intercreditor Agreements; 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 Lender or in a Lender's Applicable
Pro Rata Share shall require the consent of such Lender; and (iii) any change in
the duties of or indemnities in favor of the Agents shall require the consent of
the Administrative Agent.  Notwithstanding anything to the contrary herein, the
Administrative Agent, the Co-Agents and the Majority Lenders may modify, amend,
restate, supplement or waive any provision of ARTICLE X, other than SECTION
10.13, and ARTICLE XII without the consent of the Borrowers; PROVIDED,
FURTHER, that amendments or waivers of this Agreement are subject to the
Intercreditor Agreements.

      13.7.     EFFECT OF WAIVERS; MODIFICATION OF DOCUMENTS.  The
Administrative Agent's, the Co-Agents', the Collateral Agent's or the 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 Administrative
Agent, the Co-Agents, the Collateral Agent or the Lenders thereafter to demand
strict compliance and performance therewith.  Any suspension or waiver by the
Administrative Agent, the Co-Agents, the Collateral Agent or the 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 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.  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 Administrative Agent or the Majority Lenders or All 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.

      13.8.     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
Lenders.

                (b)   Any Lender may at any time grant to one or more of the
Existing Lenders (each a "Participant") participating interests in its
Commitment or any or all of its Loans.  In the event of any such grant by a
Lender of a participating interest to a Participant, whether or not upon notice
to the Borrowers and the Administrative Agent, such Lender shall remain
responsible for the performance of its obligations hereunder, and the Borrowers
and the Administrative Agent shall continue to deal solely and directly with
such Lender in connection with such Lender's rights and obligations under this
Agreement.  Any agreement pursuant to which any Lender may grant such a
participating interest shall provide that such 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 III 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)   Lenders may at any time assign to one or more of the
Existing Lenders or an Affiliate thereof (each an "Assignee") all of its rights
and obligations under this Agreement and the Notes 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 Lender in
substantially the form attached hereto as EXHIBIT E.  Upon execution and
delivery of such instrument and payment by such Assignee to such transferor
Lender of an amount equal to the purchase price agreed to between such
transferor Lender and such Assignee, such Assignee shall be deemed to be a
Lender under this Agreement and shall have all of the rights and obligations of
a Lender with a Commitment as set forth in such instrument of assumption, and
the transferor Lender shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required.  Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Lender, the Administrative Agent and the Borrowers shall
make appropriate arrangements so that new Notes are issued to the Assignee and
an updated Schedule of Lenders is annexed to the Credit Agreement.  If the
Assignee is not incorporated under the laws of the United States or a state
thereof, then it shall deliver to the Borrowers and the

purpose of reference and are not to be considered as construing or interpreting
the provisions hereof or thereof.

shall not be deemed to be in conflict or inconsistent with this Agreement and
shall be given full force and effect.

      13.12.    SEVERABILITY.  If any portion of this Agreement, the Notes 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 consummation of the
issuance of the Notes, the grant of collateral security therefor, and the

PERMITTED BY LAW OR AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT, THE CO-AGENTS
OR ANY LENDER TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWERS OR THEIR
PROPERTIES IN THE COURTS OF ANY OTHER JURISDICTIONS.

                               OVERRIDE AGREEMENT


            This Override Agreement (the "Agreement") dated as of July 31, 1995
is entered into among Morrison Knudsen Corporation ("MKD"), a Delaware
corporation, and Morrison Knudsen Corporation ("MKO"), an Ohio corporation (each
a "Borrower" and collectively the "Borrowers"), and the banks and other
financial institutions named herein and whose names appear on the signature
pages hereof (each, together with its successors and assigns an "Existing
Lender" and collectively, the "Existing Lenders"), and Mellon Bank, N.A. as the
agent for the Existing Lenders (in such capacity, the "Agent").

            The parties hereto agree as follows:

                                    RECITALS

      A.    The Borrowers are currently indebted to certain of the Existing
Lenders (the "Bridge Loan Lenders") in the amount of approximately $77,000,000
(the "Bridge Loan"), pursuant to that certain Credit Agreement dated as of April
11, 1995, as amended April 25, 1995 and June 1, 1995 (the "Bridge Loan
Agreement").

      B.    MKO and MKD have obligations (funded, contingent or otherwise) of
$521,592,587 (the "Existing Indebtedness") to the Existing Lenders pursuant to
the terms of the respective loan agreements and other financing arrangements set
forth on the Schedule of Existing Lenders attached hereto as SCHEDULE A (as
heretofore amended and as amended hereby, the "Existing Agreements").

      C.    The Borrowers are currently indebted to Fidelity and Deposit Company
of Maryland and Colonial American Casualty and Surety Company and certain other
sureties for payment and/or performance bonds.

      D.    The Borrowers have requested, and the Existing Lenders, the Bridge
Loan Lenders, Fidelity and Deposit Company of Maryland and Colonial American
Casualty and Surety Company have agreed to, a restructuring of the Existing
Indebtedness and the Bridge Loan, the establishment of an interim credit
facility to finance the operations required in connection with the Metra
Contract (as hereinafter defined) (the "Metra Transaction"), and the
establishment of an as yet unformed and unnamed limited liability company
("T-Co") as contemplated by the terms of the T-Co Term Sheet (as hereinafter
defined) (the "T-Co Transaction").  The Borrowers anticipate that T-Co will be
formed by September 1, 1995, and that prior to such formation, certain of the
Existing Lenders will advance funds to MKO's transit division (the "Transit
Division") pursuant to various credit facilities as set forth in the T-Co Term
Sheet (the "Interim T-Co Transaction").  The restructuring of the Existing
Indebtedness, the Bridge Loan,


                                        1
<PAGE>



the Metra Transaction and the Interim T-Co Transaction shall collectively be
referred to as the "Restructuring."

      E.    The Borrowers are in default under various provisions of the
Existing Agreements.

      F.    In connection with the Restructuring, the Borrowers have requested
the Existing Lenders to (i) make certain agreements concerning the respective
rights and remedies of the Existing Lenders under the Existing Agreements
arising from the defaults thereunder; and (ii) amend certain provisions of the
Existing Agreements.  In addition, the Borrowers have requested the Bridge Loan
Lenders to amend and restate the Bridge Loan Agreement to, among other things,
increase the amount of the secured loans to up to approximately $129,000,000 to
be used for non-Transit Division working capital purposes.

      G.    The Existing Lenders have agreed to such requests on the terms and
conditions set forth herein and in the documents executed in connection
herewith, including the condition that the Borrowers secure their obligations
under this Agreement with substantially all of their assets other than certain
assets associated with the Transit Division.

      In consideration of the foregoing, MKD, MKO, each of the Existing Lenders
and the Agent hereby agree as follows:

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 the Obligations (other than Existing Contingent Indebtedness and the
Metra Obligations that do not constitute 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.

      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 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


                                        24
<PAGE>



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 of payment.

      2.8.      OPTIONAL PREPAYMENTS.

                (a)   Subject to the terms and conditions of the Intercreditor
Agreements, the Borrowers may, upon at least one Business Day's notice to the
Agent, prepay all or any portion of the Existing Indebtedness and the Deferred
Interest, 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, by paying
the principal amount to be prepaid together with accrued interest thereon to the
date of prepayment.  Each such optional prepayment 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 or Pro Rata
Share of Deferred Interest 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 Pro Rata Share or Pro Rata Share of
Deferred Interest of such prepayment and such notice shall not thereafter be
revocable by the Borrowers.

      2.9.      MANDATORY PREPAYMENT.  Subject to the terms and conditions of
the Intercreditor Agreements, 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 each Existing Lender in an
amount equal to such Existing Lender's Pro Rata Share or Pro Rata Share of
Deferred Interest 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 or the Agent of Net Cash Proceeds of (i) any sale, lease
or other disposition of assets (other than 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) issuance of capital stock by the
Borrowers or (iii) insurance proceeds, the Borrowers shall pay or cause to be
paid such Net Cash 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


                                        25
<PAGE>

                (b)   Immediately upon receipt by the Borrowers of any repayment
or prepayment of the MK Rail Note, the Borrowers shall pay the amount of such
payment received in connection with the MK Rail Note to the Agent on account of
the Obligations for the benefit of the Existing Lenders.

                (c)   Immediately upon receipt by the Borrowers of any tax
refund, the Borrowers shall pay or cause to be paid the amount of such tax
refunds to the Agent on account of the Obligations for the benefit of the
Existing Lenders.

      2.10.     APPLICATION OF PAYMENTS.  Subject to Section 4.5 of the
Collateral Agent Agreement, all payments (including prepayments, but excluding
(a) payments made from proceeds of Metra Collateral, and (b) regularly scheduled
payments of interest, Facility Fees and Letter of Credit Fees not constituting
Deferred Interest), on any of the Obligations (other than Obligations under
the Cash Management System which shall be paid pursuant to Section 4.5 of the
Collateral Agent Agreement) shall be made to the Agent for application against
the Borrowers' Obligations as follows (regardless of how each Existing Lender
may treat such payments for purposes of its own accounting):  FIRST to then
due and outstanding fees, expenses or other charges of the Agent, the Steering
Committee Lenders or the Collateral Agent under this Agreement or any of the
other Loan Documents to the extent payable by the Borrowers; SECOND to
interest on Deferred Interest (to the extent then due); THIRD ratably 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; FOURTH to Deferred Interest (to the extent then due);
FIFTH to the unpaid principal amount of the Obligations including on account
of Existing Contingent Indebtedness and the Metra Obligations; SIXTH to all
other Obligations.

      2.11.     GENERAL PROVISIONS AS TO PAYMENTS.

                (a)   The Borrowers shall make each payment (other than payments
made from proceeds of Metra Collateral) 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, Letter of Credit Fees with respect to
the NYCTA/PB/Metro North Letters of Credit and Letter of Credit Fees with
respect to the Metra Letter of Credit), not later than


                                        26
<PAGE>



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 SECTION 2.10 and this SECTION 2.11, the Agent will promptly distribute to
each Existing Lender its share of the interest, Facility Fees and Letter of
Credit Fees paid, and its Pro Rata Share of any principal payments made under
this Agreement and its Pro Rata Share of Deferred Interest of each such payment
received by the Agent for the account of the Existing Lenders (or, in the case
of payments to the Metra Lenders with respect to payments on the Metra
Obligations hereunder, Agent will promptly distribute to the Metra Agent the
aggregate amount payable based on all Metra Lenders' shares of the interest,
Facility Fees and Letter of Credit Fees paid, and their aggregate Pro Rata
Shares of any principal payments made under this Agreement and their aggregate
Pro Rata Shares of Deferred Interest of each such payment, for allocation and
distribution by the Metra Agent among the Metra Lenders and the "Issuing Banks"
under the Metra Reimbursement Agreement in accordance with the provisions of the
Metra Reimbursement Agreement).  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.  Upon receipt by the Agent of any such payment from the
Borrowers, or from the Existing Lenders 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 shall be reinstated to the extent the Agent makes
such payment.  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)   Each Existing Lender shall be entitled to its share of the
interest, Facility Fees and Letter of Credit Fees paid, its Pro Rata Share of
any principal payments made under this Agreement and its Pro Rata Share of
Deferred Interest, including on account of Existing Contingent Indebtedness and
the Metra Obligations.  The Agent shall make the distributions on account of the
Existing Contingent Indebtedness and the Metra


                                        27
<PAGE>



Obligations into an account established pursuant to SECTION 6.1 of the
Collateral Agent Agreement (the "Contingent Indebtedness Account").

                (c)   Subject to SECTION 2.11(e), in the event that Conversion
Events have occurred with respect to Existing Contingent Indebtedness or the
Metra Obligations since the date of the last Recalculation (or, in the case of
any Recalculations to occur as of October 1, 1995, since the Closing Date), the
Agent shall request the Collateral Agent to disburse funds from the Contingent
Indebtedness Account to the Agent for distribution to the Metra Agent for the
benefit of the Metra Lenders or 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 or each Metra Lender, as the case may
be, shall receive cash bearing the same proportion to the amount of Existing
Contingent Indebtedness or the Metra Obligations 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 on July 1, 1995 bears to the outstanding principal amount of such
Existing Loans as of July 1, 1995.

                (d)   If any Reductions in Liability shall occur at any time
with respect to any Existing Contingent Indebtedness or the Metra Obligations,
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 made 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 and Metra Obligations 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 the Metra Obligations as provided in SECTION
2.11(b).

                (e)   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 Reduction Equalization Event.  If the Metra
Reduction Equalization Event has occurred, the Agent shall


                                        28
<PAGE>



distribute funds from the Metra Holdback to the Metra Agent for the benefit of
the Metra Lenders in the amount that would cause the Metra Exposure Reduction to
equal the Non-Metra Exposure Reduction as of the date of such distribution;
PROVIDED that, if the Metra Exposure Reduction exceeds the Non-Metra Exposure
Reduction and all interest, fees and costs under the Existing Loans accrued as
of the date of the distribution have not been paid in full (including Deferred
Interest), such funds shall not be disbursed from the Metra Holdback until such
time as such interest, fees and costs have been paid in full.

      2.12.     RECALCULATION.  On the Closing Date and on the first day of
each calendar quarter, commencing with the calendar quarter beginning October 1,
1995, or at such other times as may be requested by the Majority Lenders, the
Agent shall recalculate (a "Recalculation") each Existing Lender's Existing
Contingent Indebtedness, Existing Loans and Metra Obligations on the basis of
Reallocation Certificates 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 Closing Date, 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 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.  On the Closing Date
and no later than 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


                                        29
<PAGE>



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.  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.

      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 will establish, on or
prior to the Closing Date, and each Borrower will maintain until the Obligations
have been paid in full, the Cash Management System described in SCHEDULE E.

      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.


                                        30
<PAGE>



                (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 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.


                                  ARTICLE III

               ADDITIONAL AMENDMENTS TO THE EXISTING AGREEMENTS
                      AND EFFECT ON EXISTING AGREEMENTS

      3.1.      WAIVER OF COVENANTS.  Except to the extent provided in the

and Guarantors' obligations to comply with any of the terms contained in the
Existing Agreements from the date hereof through the Termination Date, other
than


                                        31
<PAGE>



(i) terms with respect to the payment of principal, interest and fees in respect
of the Existing Loans and payment of reimbursement obligations, interest thereon
and Letter of Credit Fees in respect of Existing Letters of Credit, and any
guaranty with respect to such payment (in each case, which terms shall be
modified as provided herein), and (ii) terms providing for the ongoing payment
of Letter of Credit Fees under the Metra Reimbursement Agreement and the
reimbursement agreements applicable to which the NYCTA/PB/Metro North Letters of
Credit were issued, (b) waives all defaults and events of default existing on
the Closing Date or which may arise on or after the Closing Date under any
Existing Agreement to which it is a party due to (i) the execution, delivery or
performance of the Loan Documents and the other Restructuring Documents, (ii)
the incurrence by the Borrowers and any of the Guarantors of obligations under
the Loan Documents and the other Restructuring Documents, and (iii) the granting
of the security interests, liens and mortgages to secure such obligations under
the Loan Documents and the other Restructuring Documents, (c) waives compliance
with the provisions in any Existing Agreement to which it is a party that may
result in the creation of a Lien under its Existing Agreement upon the
execution, delivery or performance of the Loan Documents or other Restructuring
Documents; (d) agrees that neither the execution and delivery nor performance of
the Loan Documents or the other Restructuring Documents by the Borrowers or the
Guarantors will conflict with or result in a default or creation of a Lien under
any Existing Agreement to which it is a party; and (e) waives all breaches and
defaults occurring or existing under the Existing Agreements on or prior to the

or remedies it may have under its Existing Agreements, including any rights or
remedies it may have to accelerate the Borrowers' or the Guarantors' obligations
under its Existing Agreements (if not previously accelerated), to terminate its
Existing Agreements (if not previously terminated), or to enforce its interest
in its Individual Collateral other than Individual Collateral securing
obligations under the Metra Interim Credit Agreement, if such rights or remedies
arise solely because of the termination of its Existing Agreements or the
Borrowers' or the Guarantors' default under its Existing Agreements prior to the
date of this Agreement.

      3.3.      TERM.  The rights and obligations of the Borrowers
arising under this Agreement with respect to any Existing Lender, and the rights

<PAGE>



force and effect with respect to such Existing Lender including at all times
after the Termination Date unless and until the Borrowers shall have paid and
performed all of their obligations under such Existing Lender's Existing
Agreements, as modified by this Agreement.

amends each Existing Lender's Existing Agreements and in the event of any
conflict between the terms hereof and the terms of any Existing Agreements or
any instruments, documents or agreements executed in connection therewith with
respect to the subject matter, the terms of this Agreement and the Loan
Documents shall govern and control.  Each of the Existing Agreements and such
other related instruments, documents or agreements, and all obligations of the
Borrowers and Guarantors and all rights and remedies of each Existing Lender

                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:

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

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

Agreement and each of the other Restructuring Documents executed by it and to

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, the use of proceeds thereof, and the
performance by the Borrowers and the Guarantors (a) do not conflict with or

authorizations of, filings with, and acts by or with respect to all Governmental

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 or the other Restructuring Documents, have been
obtained, made or taken, and remain in effect.  All applicable waiting periods

      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)

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

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

      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 Closing

transactions contemplated by the Restructuring Documents will be, in full force
and effect in accordance with the terms thereof.  Except as previously disclosed

there are no defaults by the Borrowers or

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.  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.

      6.9.      CORRECTNESS OF COLLATERAL SCHEDULES.  The Certification of

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,

property and assets described in the Security Documents capable of being
perfected by the filing of a Financing Statement, subject only to Permitted
Liens.

      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


                                        38
<PAGE>



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 or the
posting of a bond or other security under ERISA or the Internal Revenue Code or

<PAGE>



      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
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Materials, and any actual or potential liabilities to
third parties, including employees, and any


                                        40
<PAGE>



related costs and expenses).  On the basis of this review, the Borrowers have
reasonably concluded that such associated liabilities and costs, including the
costs of compliance with Environmental Laws, are unlikely to have or result in a
Material Adverse Effect.

      6.19.     NO MATERIAL ADVERSE EFFECT.  Since June 26, 1995, there has
been no Material Adverse Effect, other than as disclosed in SCHEDULE 6.19.

      6.20.     CONSOLIDATED SUBSIDIARIES; SUBSIDIARIES.  Each of the
Borrowers' and the Guarantors' Consolidated Subsidiaries is a corporation or
other entity duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization, and has all legal powers and all
material governmental licenses, authorizations, consents and approvals required
to carry on its business as now conducted.  Set forth on SCHEDULE 6.20 is a
complete and correct list of each of the Borrower's Subsidiaries.  Set forth on
SCHEDULE D is a complete and correct list of each of the Borrower's
wholly-owned Subsidiaries other than foreign wholly-owned subsidiaries, Emkay
Development Company, Inc. and Emkay Capital Investments, Inc.

      6.21.     MARGIN SECURITIES.  Neither Borrower nor any Guarantor is
engaged principally in, nor has as one of its most important activities, the
business of extending credit for the purpose of purchasing or carrying "margin
stock" as that term is defined in Regulation U promulgated by the Board of
Governors of the Federal Reserve System, as now in effect.  No part of the
Existing Indebtedness or Indebtedness otherwise created in connection with this
Agreement or the other Restructuring Documents, shall be used, directly or
indirectly, for the purpose of purchasing any such margin stock.  If requested
by the Agent, the Borrowers shall furnish or cause to be furnished to the Agent
a statement, in conformity with the requirements of Federal Reserve Form U-1
referred to in Regulation U, to the foregoing effect.

      6.22.     INVESTMENT COMPANY ACT.  Neither of the Borrowers nor any
Guarantor is an "investment company" nor a company "controlled" by an investment
company within the meaning of the Investment Company Act of 1940, as now in
effect.

      6.23.     BUSINESS LOCATIONS AND TRADE NAMES.  Set forth on SCHEDULE
6.23A is a complete and correct list of each location where each of the
Borrowers and the Guarantors maintains its chief executive office, its principal
place of business, an office, a place of business or any material financial
records.  Set forth on SCHEDULE 6.23B is a complete and correct list of each
name under or by which each Borrower and Guarantor conducts its business, or by
which each Borrower and Guarantor (or its predecessors in interest) has
conducted its business during the past five years.



                                        41
<PAGE>



      6.24.     TITLE TO REAL PROPERTY AND OTHER ASSETS.  The Borrowers and
the Guarantors have good and marketable title (or good and marketable leasehold
interests with respect to leased property) to all their Real Property and all
personal property assets and fixtures subject to no Liens other than Permitted
Liens.  The Borrowers and the Guarantors hold directly the fee and leasehold
interest in all facilities constituting the Real Property Collateral.  As of the
Closing Date, there are no contracts or options by either Borrower, any
Guarantor or any of their Subsidiaries for the sale or lease of any of the Real
Property Collateral, except as set forth on SCHEDULE 6.24.  All easements,
servitudes and rights of way necessary to the operations presently conducted or
proposed to be conducted at the facilities constituting the Real Property
Collateral have been obtained.

      6.25.     LABOR MATTERS.  There are no controversies pending between the
Borrowers, the Guarantors or their Subsidiaries and their employees which may
constitute or result in a Material Adverse Effect.

      6.26.     EMPLOYMENT AND INVESTMENT AGREEMENTS.  Set forth in SCHEDULE
6.26 is a complete and accurate list of (i) all employment agreements and
executive compensation arrangements to which any Borrower, any Guarantor or any
Subsidiary of a Borrower or a Guarantor is a party which provides for aggregate
compensation to any Person (assuming compliance with or satisfaction of all
contingencies or conditions) of more than $150,000 per year, and (ii) all
agreements relating to the voting or disposition of any outstanding shares of
capital stock of each Borrower, Guarantor or any of their Subsidiaries.  The
Borrowers and the Guarantors have delivered to the Agent a true and complete
copy of each of the agreements required to be listed in SCHEDULE 6.26.

      6.27.     NO MISSTATEMENTS.  Neither this Agreement, the other
Restructuring Documents, nor any document, instrument and other agreement,
certificate, statement or other information referred to herein or expressly
furnished to the Agent or to any of the Existing Lenders pursuant hereto or
thereto, contains any misstatement of a material fact or omits to state any
material fact or any fact necessary to make the statements contained herein or
therein not misleading on the date furnished or on the Closing Date, except as
otherwise subsequently disclosed to the Agent and all Existing Lenders in
writing on or prior to the Closing Date.

      6.28.     RESTRUCTURING.  The Restructuring has occurred.

      6.29.     MK RAIL LOCK BOX.  Lock Box number 98485 maintained at Bank of
America Illinois is used solely for collections related to MK Rail and not
collections related to any Borrower or any Guarantor.  No Borrower or Guarantor
has instructed any


                                        42
<PAGE>



account debtor or other person owing any monies to such Borrower or such
Guarantor to make any payment to Lock Box number 98485.

      6.30.     CASH MANAGEMENT SYSTEM.  Each Borrower acknowledges that the
Cash Management System is part of this Agreement and that each of the
representations and warranties made by each Borrower in the Cash Management
System constitutes representations and warranties of this Agreement.

liabilities shall be read into this Agreement and the other Loan Documents or
otherwise exist against the Agent.

      10.2.     THE AGENT AND AFFILIATES.  The Agent shall have the same
rights and powers under this Agreement as any other Existing Lender and may

generally engage in any kind of business with either Borrower or any Subsidiary
or Affiliate of either Borrower as if it were not the Agent hereunder.

      10.3.     RETENTION OF DOCUMENTS AND INFORMATION TO THE EXISTING
LENDERS.  The Agent shall deliver to each Existing Lender any material
documents and written information required under this Agreement to be delivered

powers or execute any of its duties under this Agreement and the other Loan
Documents by or through one or more agents or attorneys-in-fact and shall be

pertaining to such rights and duties.  The Agent may utilize the services of
such agents and attorneys-in-fact as the Agent in its sole discretion reasonably
determines, and all fees and expenses of such agents and attorneys-in-fact shall

      10.5.     LIMITATION OF LIABILITY.  Neither the Agent nor their
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(a) liable for any waiver, consent or approval given or any action taken or
omitted to be given or taken by them or by such Person under or in connection
with this Agreement or the other the Loan Documents or (b) responsible for the
consequences of any oversight or error in judgment by them or such Person
whatsoever, except for their or such Person's own gross negligence or willful
misconduct.  The Agent shall not be responsible for (v) the execution, validity,
enforceability, effectiveness or genuineness of this Agreement or the other Loan
Documents or Existing Agreements, (w) the collectability of any amounts owing
under this Agreement or the other Loan Documents or Existing Agreements, (x) the
value, sufficiency, enforceability or collectability of any Collateral security
therefor, (y) the failure by any Borrower to perform its Obligations hereunder
or (z) the truth, accuracy and completeness of the recitals, statements,
representations or warranties made by any Borrower or any officer or agent
thereof contained in this Agreement, the other Loan Documents or Existing
Agreements or in any certificate, report, statement or other document referred
to or provided for in, or received by the Agent in connection with, this
Agreement or the other Loan Documents or Existing Agreements.

      10.6.     RELIANCE BY THE AGENT.  The Agent shall not have any
obligation (a) to ascertain or to inquire as to the observance or performance of
any of the conditions, covenants or agreements in this Agreement or the other
Loan Documents or in any document, instrument or agreement at any time
constituting, or intended to constitute, collateral security therefor, (b) to
ascertain or inquire as to whether any notice, consent, waiver or request
delivered to them shall have been duly authorized or is genuine, accurate and
complete, or (c) to inspect the properties, books or records of the Borrowers.
The Agent shall be entitled to rely, and shall be fully protected in relying,
(x) upon any writing, resolution, notice, consent, certificate, affidavit,
letter, cablegram, telegram, telecopy, telex or teletype message, statement,
order or other document, instrument or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons, or (y) upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent.  The Agent may deem and
treat each Existing Lender party hereto or any Assignee as an Existing Lender
for all purposes unless a written notice of the assignment, negotiation or
transfer thereof, in accordance with the provisions of this Agreement shall have
been delivered to the Agent identifying the name of any successor or Assignee.
The Agent shall be entitled to fail or refuse, and shall be fully protected in
failing or refusing, to take any action under this Agreement or the other Loan
Documents unless (a) it first shall receive such advice or concurrence of the
Majority Lenders as it deems appropriate, or (b) it first shall be indemnified
to its satisfaction by the Existing Lenders against any and all


                                        61
<PAGE>



liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.  In all cases the Agent shall be fully
protected in acting, or in refraining from acting, under this Agreement or the
Loan Documents in accordance with a request of the Majority Lenders, and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Existing Lenders and all future holders of Existing Indebtedness.

      10.7.     NOTICE OF DEFAULT.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default unless the Agent
has received notice from an Existing Lender or the Borrowers referring to this
Agreement, describing such Event of Default and stating that such notice is a
"notice of default."  If the Agent receives such a notice or has actual
knowledge of the occurrence of an Event of Default, the Agent promptly shall
give notice thereof to the Existing Lenders.  The Agent shall take such action
with respect to such Event of Default as shall be directed by the Majority
Lenders; PROVIDED, HOWEVER, that unless and until the Agent shall have
received such directions, the Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Event of
Default as it deems advisable in the best interests of the Existing Lenders.

      10.8.     NON-RELIANCE ON THE AGENT AND THE OTHER EXISTING LENDERS.
Each Existing Lender expressly acknowledges that neither the Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or affiliates has
made any representations or warranties to it.  The Agent shall have no
obligation or liability to any of the Existing Lenders regarding the
creditworthiness or financial condition of any Borrower.  No act by the Agent
hereinafter taken, including any review of the Borrowers, shall be deemed to
constitute any 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


                                        62
<PAGE>



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 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 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 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 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


                                        65
<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


                                        66
<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


                                        67
<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


                                        68
<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


                                        69
<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


                                        70
<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, excluding the T-Co Interim Credit Agreement.  Any such
set-off rights will be subject to the Intercreditor Agreements.

                (b)   Each Existing Lender (other than (1) the Metra Lenders
solely with respect to the Metra Collateral and the Letter of Credit Fees under
the Metra Reimbursement Agreement, and (2) Citibank, N.A., Morgan Guaranty Trust
Company of New York and PNC Bank, N.A. with respect to Letter of Credit Fees
under the reimbursement agreements under which the NYCTA/PB/Metro North 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
SECTIONS 2.10 or 2.11, 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 Obligations as
provided in SECTION 2.11(b), and until so delivered, 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


                                        71
<PAGE>



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 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.

                (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 Reimbursement Agreement 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 (other than the
Metra Lenders with respect to the Metra Collateral in connection with the Metra
Interim Credit Agreement).  The Agent shall deposit such property with the
Collateral Agent and upon the liquidation of such property, such property shall
be


                                        72
<PAGE>



distributed to the Existing Lenders as provided in SECTION 2.11 and applied to
the Obligations as provided in SECTION 2.10.

                (e)   Each Existing Lender agrees to the provisions of this
SECTION 12.5 on behalf of any assignee under its Existing Agreement or the
Metra Interim Credit 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," "Exposure," "Liquidated Contingent Liability," "Majority
Lenders," "Metra Exposure Reduction," "Metra Final Accounting Date," "Metra
Reduction Equalization Event," "Non-Metra Exposure Reduction," "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 12.22, (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 Agreements, 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 Agreements.

      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


                                        73
<PAGE>



Documents, shall not suspend, waive or affect any other Default 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 Agreements, 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)   Prior to the earlier to occur of September 1, 1995, or the
consummation of the T-Co Transaction any Existing Lender may at any time grant
to one or more of the Existing Lenders (each a "Participant") participating
interests in or any or all of its Existing Indebtedness.  After the earlier to
occur of September 1, 1995, or the consummation of the T-Co Transaction, any
Existing Lender may at any time grant a participating interest in its Existing
Indebtedness to any Person.  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)   Prior to the earlier to occur of September 1, 1995, or the
consummation of the T-Co Transaction, any Existing


                                        74
<PAGE>



Lender may at any time assign to one or more of the Existing Lenders (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 C.  After the
earlier to occur of September 1, 1995 or consummation of the T-Co Transaction,
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 C.  Upon execution and
delivery of such instrument and payment by such Assignee to such transferor
Existing Lender of an amount equal to the purchase price agreed to between such
transferor Existing Lender and such Assignee, such Assignee shall be deemed to

corporation, and MORRISON KNUDSEN CORPORATION ("MKO"), an Ohio corporation (each
a "Borrower," and collectively, the "Borrowers"), the banks and other financial
institutions named on SCHEDULE A hereto (the "Schedule of Lenders") and whose
signatures appear on the signature pages hereto (each, together with its
successors and assigns, a "Lender," and collectively, the "Lenders"), and Mellon
Bank, N.A., as agent for the Lenders (in such capacity, the "Agent").

            The parties hereto agree as follows:


                                 RECITALS

      A.    MKO and MKD have obligations (funded, contingent or otherwise) in
excess of $521,600,000 (the "Existing Indebtedness") to certain lenders or their
predecessors in interest (the "Existing Lenders") pursuant to the terms of the
respective loan agreements and other financing arrangements set forth on the
Schedule of the Existing Lenders attached hereto as SCHEDULE B (the "Existing
Agreements").

      B.    The Borrowers are entering into that certain Amended and Restated
Credit Agreement of even date herewith (the "Bridge Loan Agreement"), pursuant
to which certain of the Existing Lenders (the "Bridge Loan Lenders") are
continuing to make loans and other financial accommodations available to the
Borrowers (the "Bridge Loan").

      C.    The Borrowers are currently indebted to Fidelity and Deposit Company
of Maryland and Colonial American Casualty and Surety Company and certain other
sureties for payment and/or performance bonds.

      D.    The Borrowers have requested, and the Lenders, the Existing Lenders,
Fidelity and Deposit Company of Maryland, and Colonial American Casualty and
Surety Company have agreed to, a restructuring of the Existing Indebtedness and

terms of the T-Co Term Sheet (as hereinafter defined) (the "T-Co Transaction").
The Borrowers anticipate that T-Co will be formed by September 1, 1995, and that
prior to such formation, certain of the Lenders will advance funds to MKO's
transit division (the "Transit Division") pursuant to various credit facilities
as set forth in the T-Co Term Sheet.  The restructuring of the Existing

Agreement is being guaranteed by the Bonding Company, and such guaranty is being
backed by a letter of credit.  Pursuant to the Five Party Agreement (as defined

Agreement.

and conditions set forth herein and in the documents executed in connection
herewith, including the condition that MKO secure the Borrowers' Obligations

defined below).

      In consideration of the foregoing, MKD, MKO, the Agent and each of the
Lenders hereby agree as follows:

that such Lender has made such Pro Rata Share available to the Agent on the date
of such Borrowing in accordance with subsection (b) of this SECTION 2.3 and
the Agent may, in reliance upon such assumption, make available to the Borrowers
on such date a corresponding amount.  If and to the extent that such Lender

and the Borrowers severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrowers until the date such amount is

thereof appropriate notations to evidence the foregoing information with respect
to each such Loan then outstanding; PROVIDED, that the failure of any Lender
to make any such recordation or endorsement shall not affect the obligations of
either Borrower hereunder or under the Notes absent manifest error.  Each Lender
is hereby irrevocably authorized by each Borrower so to endorse its Note and to
attach to and make a part of any Note a continuation of any such schedule as and
when required.

payments for purposes of its own accounting):  FIRST to then due and
outstanding fees, expenses or other charges of the Agent, or the Steering
Committee Lenders under this Agreement or any of the other Loan Documents to the
extent payable by the Borrowers; SECOND to then due interest on the Loans
accrued and unpaid prior to the date such funds are received by the Lenders; and

Schedule for Notices.  Subject to the provisions of SECTION 2.9, the Agent
will promptly distribute to each Lender entitled to receive a portion of such
payment its Pro Rata Share of each such payment received by the Agent for the
account of the Lenders.  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 2.9 and is not paid by the
Borrowers within one (1) Business Day after the Agent's demand therefor, then
each Lender shall pay to the Agent the share of such returned payment received
by it.  Upon receipt by Agent of any such payment from the Borrowers, or from
the Lenders in the event the Borrowers fail to make such payment after Agent's
demand, 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 Loans shall be reinstated to the
extent the Agent makes such payment.  Whenever any payment of principal of, or
interest on, the Loans or of fees with respect to the Loans or of any other
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


                                        21
<PAGE>



operation of law or otherwise, interest thereon shall be payable for such
extended time.

prior to the Closing Date, and each Borrower will maintain until the Obligations

setting forth the additional amount or amounts to be paid to it hereunder shall

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

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
3.2) paid by such 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 Lender or
the Agent (as the case may be) makes demand therefor.

                (c)   Each 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 Lender listed on the signature pages
hereof and on or prior to the date on which it becomes a Lender in the case of

States withholding tax or reduces the rate of withholding tax on payments of
interest for the account of such 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 a Lender has failed
to provide the Borrowers with the appropriate form pursuant to SECTION 3.2(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 to be
provided), such Lender shall not be entitled to indemnification under


                                        23
<PAGE>



SECTION 3.2(b) or (c) with respect to Taxes imposed by the United States on
payments by such Borrower; PROVIDED, that if a 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 Lender shall reasonably request to assist such
Lender to recover such Taxes.

                (e)   If either Borrower is required to pay additional amounts
to or for the account of any Lender pursuant to this SECTION 3.2, then such
Lender will change the jurisdiction of its lending office to an office it
maintains if, in the judgment of such Lender, such change (i) will eliminate or

                In order to induce the Agent and the Lenders to enter into this
Agreement, and to make the Loans and other financial accommodations provided for
herein, the Borrowers hereby make the following representations and warranties
to the Agent and to each Lender:

      6.1.      ORGANIZATION AND QUALIFICATION.  Each of the Borrowers 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 has the corporate power and has taken all


                                        27
<PAGE>



corporate action necessary to authorize it to execute, deliver, and perform this
Agreement and each of the other Restructuring 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 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 may be subject to or limited
by bankruptcy, insolvency, reorganization, arrangement, moratorium or 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 Notes, the other Restructuring Documents and the secured
financing transactions contemplated hereby, the use of proceeds thereof, and the
performance by the Borrowers (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, any material Requirement of Law or any
Contractual Obligation of any Borrower, (b) do not conflict with, constitute a
default or require any consent under any Contractual Obligation of any Borrower,
and (c) do not result in the creation of any Lien other than a Permitted Lien
upon any property or assets of any Borrower.

      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 required to be obtained, made or taken by the
Borrowers in connection with the secured financing transactions contemplated
hereby or with the execution, delivery, performance, validity or enforceability
of this Agreement or the other Restructuring 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 6.5, 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 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.      CORRECTNESS OF SCHEDULES.  The Certification of Schedules
listed as ITEM NO. 4.24 of the Schedule of Documents and delivered to the
Agent in connection herewith is complete and correct in all material respects.

of the Borrowers and their Consolidated Subsidiaries as of the date thereof, (b)

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 described in ITEM NOS. 1.41 AND 2.4 of the Schedule of
Documents and delivered to 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.

      6.9.      SECURITY DOCUMENTS.  The Security Documents to which the
Borrowers are a party create in favor of the Collateral Agent for the benefit of
the Lenders to secure the Obligations valid, and, upon the proper filing by the
Collateral Agent of Financing Statements at appropriate offices, a first
priority, perfected security interests in the property and assets described in
the Security Documents capable of being perfected by the filing of a Financing
Statement, subject only to Permitted Liens.

      6.10.     TAXES.  The Borrowers 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 or any of their properties, income or
franchises, including interest, assessments, fees and penalties (other than any
immaterial amounts, which the Borrowers 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 6.10,
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.


                                        29
<PAGE>



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

      6.12.     JUDGMENTS.  There are no outstanding or unpaid judgments
against the Borrowers in excess of (a) $100,000 individually, or (b) $2,000,000
in the aggregate, except as expressly set forth in SCHEDULE 6.12.

      6.13.     COMPLIANCE WITH LAWS.  The Borrowers are not and will not be
in violation of, or not in compliance with, any Requirement of Law binding upon
the Borrowers 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.

      6.14.     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 or the
posting of a bond or other security under ERISA or the Internal Revenue Code or
(iii) except as set forth on SCHEDULE 6.14, incurred any liability under Title
IV of ERISA other than a liability to the PBGC for premiums under Section 4007
of ERISA.

      6.15.     GOVERNMENTAL AUTHORIZATIONS; PERMITS, LICENSES AND
ACCREDITATIONS; OTHER RIGHTS.  The Borrowers 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, 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.  The Borrowers are


                                        30
<PAGE>



not 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 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 and their Consolidated Subsidiaries as now
conducted and presently proposed to be conducted.

      6.16.     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 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
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Materials, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses).  On the
basis of this review, the Borrowers have reasonably concluded that such
associated liabilities and costs, including the costs of compliance with
Environmental Laws, are unlikely to have or result in a Material Adverse Effect.

      6.17.     NO MATERIAL ADVERSE EFFECT.  Since June 26, 1995, there has
been no Material Adverse Effect, other than as disclosed in SCHEDULE 6.17.

      6.18.     CONSOLIDATED SUBSIDIARIES; SUBSIDIARIES.  Each of the
Borrowers' Consolidated Subsidiaries is a corporation or other entity duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, and has all legal powers and all material
governmental licenses,


                                        31
<PAGE>



authorizations, consents and approvals required to carry on its business as now
conducted.  Set forth on SCHEDULE 6.18 is a complete and correct list of each
of the Borrower's Subsidiaries.

      6.19.     MARGIN SECURITIES.  Neither Borrower is engaged principally
in, nor has as one of its most important activities, the business of extending
credit for the purpose of purchasing or carrying "margin stock" as that term is
defined in Regulation U promulgated by the Board of Governors of the Federal
Reserve System, as now in effect.  No part of the Indebtedness evidenced by the
Notes, or Indebtedness otherwise created in connection with this Agreement or
the other Restructuring Documents, shall be used, directly or indirectly, for
the purpose of purchasing any such margin stock.  If requested by the Agent, the
Borrowers shall furnish or cause to be furnished to the Agent a statement, in
conformity with the requirements of Federal Reserve Form U-1 referred to in
Regulation U, to the foregoing effect.

      6.20.     INVESTMENT COMPANY ACT.  Neither of the Borrowers is an
"investment company" nor a company "controlled" by an investment company within
the meaning of the Investment Company Act of 1940, as now in effect.

      6.21.     BUSINESS LOCATIONS AND TRADE NAMES.  Set forth on  SCHEDULE
6.21A is a complete and correct list of each location where each of the
Borrowers maintains its chief executive office, its principal place of business,
an office, a place of business or any material financial records.  Set forth on
SCHEDULE 6.21B is a complete and correct list of each name under or by which
each Borrower conducts its business, or by which each Borrower (or its
predecessors in interest) has conducted its business during the past five years.

      6.22.     TITLE TO REAL PROPERTY AND OTHER ASSETS.  The Borrowers have
good and marketable title (or good and marketable leasehold interests with
respect to leased property) to all their Real Property and all personal property
assets and fixtures subject to no Liens other than Permitted Liens.

      6.23.     LABOR MATTERS.  There are no controversies pending between the
Borrowers or their Subsidiaries and their employees which may constitute or
result in a Material Adverse Effect.

      6.24.     NO MISSTATEMENTS.  Neither this Agreement, the Notes, the
other Restructuring Documents, nor any document, instrument and other agreement,
certificate, statement or other information referred to herein or expressly
furnished to the Agent or to any of the Lenders pursuant hereto or thereto,
contains any misstatement of a material fact or omits to state any material fact
or any fact necessary to make the statements contained herein or therein not
misleading on the date furnished or on the Closing Date, except as otherwise
subsequently disclosed to the Agent and all Lenders in writing on or prior to
the Closing Date.

      6.26.     CASH MANAGEMENT SYSTEM.  Each Borrower acknowledges that the
Cash Management System is part of this Agreement and each of the representations
and warranties made by each Borrower in the Cash Management System constitute
representations and warranties of this Agreement.

occurrence of a Special Event of Default or at any time thereafter, after notice
and the lapse of any cure period, where applicable, and in each and every case,
until such Event of Default shall have been remedied or waived in writing in
accordance with SECTION 12.6, either one or both of the following actions may
be taken: (a) upon the request of the Majority Lenders, the Agent shall, by
notice in writing to the Borrowers, terminate any or all of the Commitments,
whereupon such Commitments of the Lenders thereunder immediately shall
terminate; and (b) upon the request of the Majority Lenders, the Agent shall, by
notice in writing to the Borrowers (a "Notice of Acceleration") declare all the
Obligations due hereunder and under the Loan Documents to be immediately due and
payable, without presentment, demand, protest or notice of any kind (other than
notices provided herein), all of which are hereby expressly waived to the extent
permitted by applicable law; PROVIDED, HOWEVER, that upon the occurrence
of any event specified in either SECTION 9.1(f) or SECTION 9.1(g) (and, in
the case of SECTION 9.1(g), after the lapse of the 20 day period referred to
therein) the Commitments shall automatically terminate, and all amounts owing
under this Agreement, the Notes and the other Loan Documents immediately shall
automatically be due and payable in full without declaration or other notice

Agent shall be entitled to all remedies available hereunder and thereunder.

                (b)   OCCURRENCE OF A STANDARD EVENT OF DEFAULT.  Upon the

Commitments of the Lenders thereunder immediately shall terminate and may
deliver a Notice of Acceleration declaring all the Obligations due hereunder and
under the Loan Documents to be immediately due and payable, without presentment,
demand, protest or notice of any kind (other than notices provided herein), all

      9.3.      OTHER REMEDIES.  Subject to the Intercreditor Agreements, upon
the occurrence of an Event of Default or at any time thereafter, after notice
and the lapse of any cure period, where applicable, and in each and every case,
until such Event of Default shall have been remedied or waived in writing in
accordance with SECTION 12.6, in addition to the remedies listed in SECTION
9.2 upon the earlier of a Notice of Acceleration or acceleration of the
Obligations, the Lenders acting by and through the Agent shall have all rights,
powers and remedies available under each of the Loan Documents and applicable
law, including (i) enforcing the Collateral Agent's security interest in the
Collateral by means of one or more public or private sales thereof, (ii) taking
possession of all or any portion of the Collateral, in person or by means of a
court appointed receiver (who shall be appointed without regard to the value of
Collateral Agent's security), and (iii) exercising any or all of the rights of a
beneficiary or secured party pursuant to applicable law.  All rights, powers and
remedies of the Agent or the Lenders in connection with each of the Loan
Documents may be exercised at any time or from time to time, are cumulative and
not exclusive, and shall be in addition to any other rights, powers or remedies
provided by law or equity.  Upon the request of the Majority Lenders after the
occurrence of an Event of Default, the Agent shall instruct the Collateral Agent
to exercise any remedies under the Loan Documents, including collection of funds
in deposit accounts and commencement of or actions in court proceedings.

      9.4.      WAIVERS BY BORROWERS.  Except as otherwise provided for in
this Agreement and applicable law, the Borrowers waive (i) presentment, demand
and protest and notice of presentment, dishonor, notice of intent to accelerate,
notice of acceleration, protest, default, nonpayment, maturity, release,
compromise, settlement, extension or renewal of any or all commercial paper,
accounts, contract rights, documents, instruments, chattel paper and guaranties
at any time held by the Agent, the Collateral Agent or the Lenders on which the
Borrowers may in any way be liable and hereby ratify and confirm whatever the
Agent, the Collateral Agent or the Lenders may do in this regard, (ii) all
rights to notice and a hearing prior to the Collateral Agent's taking possession
or control of, or replevy, attachment or levy upon, the Collateral, or any bond
or security which might be required by any court prior to allowing the Agent or
the Collateral Agent to exercise any of its remedies, and (iii) the benefit of
all valuation, appraisal and exemption laws.  Each Borrower acknowledges that it
has been advised by counsel of its choice with respect to the effect of the
foregoing waivers and this Agreement, the other Loan Documents and the
transactions evidenced by this Agreement and the other Loan Documents,
generally.

and to exercise such powers and perform such duties as are expressly delegated
to the Agent by the terms of this Agreement and the other Loan Documents,
together with such other powers as are reasonably incidental thereto.
Notwithstanding anything to the contrary herein, the Agent shall have no duties,
except those expressly set forth in this Agreement and the other Loan Documents,
and no implied covenants, responsibilities, duties, obligations or liabilities
shall be read into this Agreement and the other Loan Documents or otherwise
exist against the Agent.

      10.2.     AGENT AND AFFILIATES.  The Agent shall have the same rights
and powers under this Agreement as any other Lender and may exercise or refrain
from exercising the same as though it were not the Agent, and the Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of business with either Borrower or any Subsidiary or Affiliate of either
Borrower as if it were not the Agent hereunder.

      10.3.     RETENTION OF DOCUMENTS AND INFORMATION TO THE LENDERS.  Agent
shall deliver to each Lender any material documents and written information
required under this Agreement to be delivered by the Borrowers to Agent within a
reasonable period after the Agent's receipt of such documents or information.

      10.4.     DELEGATION OF DUTIES.  The Agent may exercise any of its
powers or execute any of its duties under this Agreement and the other Loan
Documents by or through one or more agents or attorneys-in-fact and shall be
entitled to take, and to rely on, advice of counsel concerning all matters
pertaining to such rights and duties.  The Agent may utilize the services of
such agents and attorneys-in-fact as the Agent in its sole discretion reasonably
determines, and all fees and expenses of such agents and attorneys-in-fact shall
be paid by the Borrowers on demand.  The Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by the
Agent with reasonable care.

      10.5.     LIMITATION OF LIABILITY.  Neither the Agent, nor its officers,
directors, employees, agents, attorneys-in-fact or affiliates shall be (a)
liable for any waiver, consent or approval given or any action taken or omitted

Agreement or the other the Loan Documents or (b) responsible for the
consequences of any oversight or error in judgment by them or


                                        49
<PAGE>



such Person whatsoever, except for their or such Person's own gross negligence
or willful misconduct.  The Agent shall not be responsible for (v) the
execution, validity, enforceability, effectiveness or genuineness of this
Agreement or the other Loan Documents, (w) the collectability of any amounts
owing under this Agreement or the other Loan Documents, (x) the value,
sufficiency, enforceability or collectability of any Collateral security
therefore, (y) the failure by any Borrower to perform its Obligations hereunder
or (z) the truth, accuracy and completeness of the recitals, statements,
representations or warranties made by any Borrower or any officer or agent
thereof contained in this Agreement, the other Loan Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent in connection with, this Agreement or the other Loan
Documents.

      10.6.     RELIANCE BY THE AGENT.  The Agent shall not have any
obligation (a) to ascertain or to inquire as to the observance or performance of
any of the conditions, covenants or agreements in this Agreement or the other
Loan Documents or in any document, instrument or agreement at any time
constituting, or intended to constitute, collateral security therefor, (b) to
ascertain or inquire as to whether any notice, consent, waiver or request
delivered to it shall have been duly authorized or is genuine, accurate and
complete, or (c) to inspect the properties, books or records of the Borrowers.
The Agent shall be entitled to rely, and shall be fully protected in relying,
(x) upon any writing, resolution, notice, consent, certificate, affidavit,
letter, cablegram, telegram, telecopy, telex or teletype message, statement,
order or other document, instrument or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons, or (y) upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent.  The Agent may deem and
treat each Lender party hereto or any Assignee as a Lender for all purposes
unless a written notice of the assignment, negotiation or transfer thereof, in
accordance with the provisions of this Agreement, shall have been delivered to
the Agent identifying the name of any successor or Assignee.  The Agent shall be
entitled to fail or refuse, and shall be fully protected in failing or refusing,
to take any action under this Agreement or the other Loan Documents unless (a)
it first shall receive such advice or concurrence of the Majority Lenders as it
deems appropriate, or (b) it first shall be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.  In all cases the
Agent shall be fully protected in acting, or in refraining from acting, under

Majority Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of

      10.7.     NOTICE OF DEFAULT.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default unless the Agent
has received notice from a Lender or the Borrowers referring to this Agreement,
describing such Event of Default and stating that such notice is a "notice of
default."  If the Agent receives such a notice or has actual knowledge of the
occurrence of an Event of Default, the Agent promptly shall give notice thereof
to the Lenders.  The Agent shall take such action with respect to such Event of
Default as shall be directed by the Majority Lenders; PROVIDED, HOWEVER,
that unless and until the Agent shall have received such directions, the Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Event of Default as it deems advisable in the
best interests of the Lenders.

      10.8.     NON-RELIANCE ON THE AGENT AND THE OTHER LENDERS.  Each Lender
expressly acknowledges that neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates has made any
representations or warranties to it.  The Agent shall have no obligation or
liability to any of the Lenders regarding the creditworthiness or financial
condition of any Borrower.  No act by the Agent hereinafter taken, including any
review of the Borrowers, shall be deemed to constitute any representation or
warranty by the Agent to any Lender.  Each Lender represents to the Agent that,
independently and without reliance upon the Agent or any other 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 make its Loans hereunder and to enter into this Agreement.
Each Lender also represents that, independently and without reliance upon the
Agent or any other 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
Lenders by the Agent hereunder, the Agent shall have no obligation or liability
to provide any 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
the Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

      10.9.     COLLATERAL.  Each of the Lenders represents to the Agent and
each of the other 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 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, 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 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 the 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.    AGENT IN ITS INDIVIDUAL CAPACITY.  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 Agent was not the Agent hereunder.
With respect to its Existing Indebtedness and any other Loans made or renewed by
it, Agent in its individual capacity shall have the same benefits, rights,
powers and privileges under this Agreement and the Loan Documents as any Lender
and may exercise the same as though it were not Agent, and the terms "Lender"
and "Lenders" shall include Agent in its individual capacity.

      10.12.    SUCCESSOR AGENT.  The Agent may resign as such upon ten days'
prior written notice to the Lenders.  The 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 Lenders a
successor agent for the Lenders.  A successor agent may also be appointed by the
Majority Lenders if the Agent ceases to have any Loans hereunder, 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, (b) the retiring Agent shall be discharged of all its obligations and
liabilities in such capacity under this Agreement


                                        52
<PAGE>



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 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 10.8.

      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 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 Lender
shall be in default hereunder, such default shall not affect the rights and
obligations of the Borrowers hereunder.  The Agent shall provide the Borrowers
with prompt notice of any default by any Lender.

      10.14.    AUTHORIZATION TO AGENT TO ENTER INTO AND ABIDE BY FIVE-PARTY
Agreement.  Each Lender authorizes the Agent to enter into the Five-Party
Agreement on behalf of the Lenders and to act in accordance with the terms of
the Five-Party Agreement.  In the event that there is a conflict between the
terms of this Agreement and the terms of the Five-Party Agreement, the Agent is
authorized to comply with the terms of the Five-Party Agreement.


                                  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 otherwise,
will be paid strictly in accordance with the terms of this Agreement and the
other Loan 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 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


                                        53
<PAGE>



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 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,
any Note, the other Restructuring Documents or by operation of law or otherwise;

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

                (c)   Any release, impairment, non-perfection or invalidity of
any direct or indirect security for any Obligation of the other Borrower under
this Agreement, any Note 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, any Note 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
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, any Note 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 of or
interest on


                                        54
<PAGE>



any Note 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 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, any Note 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 Commitments shall have terminated and the principal of and
interest on the Notes and all other amounts payable by the Borrowers under this
Agreement shall have been paid in full.  If at any time any payment of the
principal of or interest on any Note 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 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 THE
OBLIGATIONS BEFORE SEEKING FROM SUCH BORROWER PAYMENT IN FULL OF ITS OBLIGATIONS
TO THE AGENT AND THE LENDERS OR PROCEEDING AGAINST SUCH BORROWER FOR SAME; AND

                (b)   SUCH BORROWER AGREES THAT THE AGENT AND THE 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; OR PURSUE ANY OTHER REMEDY IN THE
AGENT'S OR ANY 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 AND EACH LENDER'S ENTERING INTO THIS
AGREEMENT AND THAT THE AGENT AND EACH 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
or its Notes 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 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 or ARTICLE III shall not be effective
until received.

      12.2.     ENTIRE AGREEMENT.  The execution and delivery of this
Agreement, the Notes 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, the Notes 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 any Note or the
other Restructuring Documents shall operate


                                        56
<PAGE>



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 on 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 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
Lender, their respective Affiliates and the respective directors, officers,
agents and employees of the foregoing (each an "Indemnitee") and hold each
Indemnitee harmless from and against any and all liabilities, losses, damages,
costs and expenses of any kind, including 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 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


                                        57
<PAGE>



gross negligence or willful misconduct or (b) in the case of any 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 OF SET-OFFS.

                (a)   In addition to any rights and remedies of the Lenders
provided by law, the 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 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 Lender
may set off and apply against any Obligations, whether matured or unmatured, of
the Borrowers to the Lenders, any amount owing from the Lenders to the
Borrowers.  No 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 Lender promptly shall notify the Borrowers
and the Agent after any such setoff and application made by any such 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 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 or any of their Consolidated Subsidiaries under any
agreements other than the Loan Documents.  Any such set-off rights will be
subject to the Intercreditor Agreements.

                (b)   Each Lender agrees that if it shall, by exercising any
right of set-off or counterclaim or otherwise, receive payment of a proportion
of the aggregate amount of principal and interest due to it which is greater
than the proportion received by any other Lender in respect of the aggregate
amount of principal and interest due to such other Lender, the Lender receiving
such proportionately greater payment shall purchase such participations in the
Loans held by the other Lenders, and such other adjustments shall be made, as
may be required so that all such payments of principal and interest with respect
to the Loans held by the Lenders shall be shared by the Lenders pro rata;
PROVIDED, that nothing in this Section shall impair the right of any Lender 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 Indebtedness of a Borrower
other than its Indebtedness hereunder.  Each Borrower agrees, to the fullest
extent it may effectively do so under applicable law, that any holder of a
participation in a Loan, whether or not


                                        58
<PAGE>



acquired pursuant to the foregoing arrangements, may exercise 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.

      12.6.     AMENDMENTS AND WAIVERS.  Any provision of this Agreement, the
Notes or the other Loan Documents may be amended or waived only if permitted by
the Five-Party Agreement and 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 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 Loans, (b) a change in the rate of
interest or fees to be paid by the Borrowers with respect to any of the Loans,
(c) a change in the definitions of "All Lenders", "Majority Lenders" or "Pro
Rata Share," (d) any increase in the total amounts of the Commitments or in any
Lender's Commitment or any change that subjects any Lender to any additional
obligation, (e) this SECTION 12.6, (f) the release of any Guarantor or any
Borrower, and (g) any change in the terms of the Letter of Credit; (ii) any
change in the duties of or indemnities in this Agreement in favor of any Lender
or in a Lender's Pro Rata Share shall require the consent of such 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 XI, other than SECTION 10.12,
without the consent of the Borrowers; PROVIDED, FURTHER, that amendments or
waivers of this Agreement are subject to the Intercreditor Agreements and to the
Five-Party Agreement.

      12.7.     EFFECT OF WAIVERS; MODIFICATION OF DOCUMENTS.  The Agent's,
the Collateral Agent's, or the 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 Lenders thereafter
to demand strict compliance and performance therewith.  Any suspension or waiver
by the Agent or the 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 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.  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
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
Lenders.

                (b)   Any Lender may at any time grant to one or more of the
Existing Lenders (each a "Participant") participating interests in its
Commitment or any or all of its Loans.  In the event of any such grant by a
Lender of a participating interest to a Participant, whether or not upon notice
to the Borrowers and the Agent, such 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 Lender in connection with such
Lender's rights and obligations under this Agreement.  Any agreement pursuant to
which any Lender may grant such a participating interest shall provide that such
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 III 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)   Lenders may at any time assign to one or more of the
Existing Lenders or an Affiliate thereof (each an "Assignee") all of its rights
and obligations under this Agreement and the Notes 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 Lender in
substantially the form attached hereto as EXHIBIT E.  Upon execution and
delivery of such instrument and payment by such Assignee to such transferor
Lender of an amount equal to the purchase price agreed to between such
transferor Lender and such Assignee, such Assignee shall be deemed to be a
Lender under this Agreement and shall have all of the rights and obligations of
a Lender with a Commitment as set forth in such instrument of assumption, and
the transferor Lender shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required.  Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Lender, the Agent and the Borrowers shall make appropriate
arrangements so that new Notes are issued to the Assignee and an updated
Schedule of Lenders is annexed to the Credit Agreement.  If the Assignee is not
incorporated under the laws of the United States or a state thereof, then it
shall deliver to the Borrowers and the Agent


                                        60
<PAGE>



certification as to its exemption from deduction or withholding of any United

Agreements and subject to the Five-Party Agreement; 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
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, the Notes 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 consummation of the
issuance of the Notes, the grant of collateral security therefor, and the
payment of principal and interest on the Loans substantially on the same terms
and subject to the same conditions as set forth herein and therein.

OTHER MANNER PERMITTED BY LAW OR AFFECT THE RIGHT OF THE AGENT OR ANY LENDER TO
BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWERS OR THEIR PROPERTIES IN THE
COURTS OF ANY OTHER JURISDICTIONS.

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.

Stock called for by this Warrant, which new Warrant shall in all other respects

any provision herein to the contrary, the Company shall not be required to

Company shall pay all expenses in connection with, and all taxes and other
governmental charges that may be imposed with respect to, the issue of the

not be required, however, to pay any tax or other charge imposed in connection
with any transfer involved in the issue of any certificate for shares of Common
Stock issuable upon exercise of this Warrant in any name other than that of

thereunder), shall continue to be entitled with respect to such shares to all
rights to which it would have been entitled as Holder under SECTIONS 9, 10, 13,
14 and 17 of this Warrant.  The Company will, at the time of each exercise of

fail to make any


                                        7
<PAGE>

SECTION 3.

        3.4    MAINTENANCE OF BOOKS.  The Company agrees to maintain, at its
aforesaid office or agency, books for the registration, and the registration of

        4.2    STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any time
the Company shall:

               (a)  take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, Additional Shares of Common Stock;

               (b)  subdivide its outstanding shares of Common Stock into a
larger number of shares of Common Stock, or

               (c)  combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock,

then (i) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (ii) the Current Warrant Price
shall be adjusted to equal (A) the Current Warrant Price in effect immediately
prior to the occurrence of such event, multiplied by the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to the


                                        9
<PAGE>



adjustment divided by (B) the number of shares for which this Warrant is
exercisable immediately after such adjustment.

        4.3    OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION.
The following provisions shall be applicable to the making of adjustments
pursuant to this SECTION 4, of the number of shares of Common Stock for which
this Warrant is exercisable:

               (a)  WHEN ADJUSTMENTS TO BE MADE.  The adjustments required by
this SECTION 4 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment of the number of
shares of Common Stock for which this Warrant is exercisable that would
otherwise be required may be postponed (except in the case of an adjustment
pursuant to SECTION 4.1 or a subdivision or combination of shares of the
Common Stock, as provided for in SECTION 4.2) up to, but not beyond the date
of exercise of this Warrant (or date of repurchase by the Company under SECTION
14) if such adjustment either by itself or with other adjustments not
previously made adds or subtracts less than one percent (1%) of the shares of
Common Stock for which this Warrant is exercisable immediately prior to the
making of such adjustment.  Any adjustment representing a change of less than
such minimum amount (except as aforesaid) which is postponed shall be carried
forward and made as soon as such adjustment, together with other adjustments
required by this SECTION 4 and not previously made, would result in a minimum
adjustment or on the date of exercise or repurchase.  For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close of
business on the date of its occurrence.

               (b)  FRACTIONAL INTERESTS.  In computing adjustments under this
SECTION 4, fractional interests in Common Stock shall be taken into account to
the nearest 1/10th of a share.

               (c)  WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver
such dividend or distribution, then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made
in respect thereof shall be rescinded and annulled.

        4.4    REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation), or sell,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger,


                                        10
<PAGE>

or acquiring corporation, or any cash, shares of stock or other securities or
property of any nature whatsoever (including warrants or other subscription or
purchase rights) in addition to or in lieu of common stock of the successor or
acquiring corporation ("Other Property"), are to be received by or distributed
to the holders of Common Stock of the Company, then each Holder shall have the
right thereafter to receive, upon exercise of such Holder's Warrant, the number
of shares of common stock of the successor or acquiring corporation and Other
Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event.  In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation shall expressly assume the due and punctual observance
and performance of each and every covenant and condition of this Warrant to be
performed and observed by the Company and all the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as
determined by resolution of the Board of Directors of the Company) in order to
provide for adjustments of the shares of Common Stock for which this Warrant is
exercisable, which adjustments shall be as nearly equivalent as practicable to
the adjustments provided for in this SECTION 4.  For purposes of this SECTION
4.4, "common stock of the successor or acquiring corporation" shall include
stock of such corporation of any class which is not preferred as to dividends or
rights on liquidation over any other class of stock of such corporation and
which is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon a specified date or
the happening of a specified event and any warrants or other rights to subscribe
for or purchase any such stock.  The foregoing provisions of this SECTION 4.4
shall similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or dispositions of assets.


5.      NOTICES TO WARRANT HOLDERS

be adjusted pursuant to SECTION 4, the Company shall forthwith prepare a
certificate to be executed by the chief financial officer of the Company setting
forth, in reasonable detail, the event requiring the adjustment and the method
by which such adjustment was calculated, specifying the number of shares of
Common Stock for which this Warrant is exercisable and (if such adjustment was
made pursuant to SECTION 4.4) describing the number and kind of


                                        11
<PAGE>



any other shares of stock or Other Property for which this Warrant is

be available for inspection at said office during normal business hours by any
Holder or any prospective purchaser of a Warrant designated by a Holder thereof.

entitled to the same rights to receive notice of corporate action as any holder
of Common Stock.

observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms.  Without
limiting the generality of the foregoing, the Company will (a) not increase the
par value of any shares of Common Stock receivable upon the exercise of this
Warrant above the amount payable therefor upon such exercise immediately prior

appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock, upon the exercise of this Warrant, and

necessary to enable the Company to perform its obligations under this Warrant.

period this Warrant is outstanding acknowledge in writing, in form reasonably
satisfactory to Holder, the continuing validity of this Warrant and the
obligations of the Company hereunder.

        APPROVAL OF ANY GOVERNMENTAL AUTHORITY; PREFERRED STOCK

        From and after the Closing Date, the Company shall at all times reserve
and keep available for issuance upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants.  All shares of Common Stock
which shall be so issuable, when issued upon exercise of any Warrant and payment
therefor in accordance with the terms of such Warrant, shall be duly and validly
issued and fully paid and nonassessable, and not subject to preemptive rights.


                                        12
<PAGE>



        Before taking any action which would cause an adjustment reducing the
Current Warrant Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and nonassessable shares of such Common Stock at
such adjusted Current Warrant Price.

        Before taking any action which would result in an adjustment in the
number of shares of Common Stock for which this Warrant is exercisable or in the
Current Warrant Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

        If any shares of Common Stock required to be reserved for issuance upon
exercise of Warrants require registration or qualification with any governmental
authority under any federal or state law (otherwise than as provided in SECTION
9) before such shares may be so issued, the Company will in good faith and as
expeditiously as possible and at its expense endeavor to cause such shares to be
duly registered or qualified.


8.      TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

        In the case of all dividends or other distributions by the Company to
the holders of its Common Stock with respect to which any provision of SECTION
4 refers to the taking of a record of such holders, the Company will in each
such case take such a record and will take such record as of the close of
business on a Business Day.  The Company will not at any time, except upon
dissolution, liquidation or winding up of the Company, close its stock transfer
books or Warrant transfer books so as to result in preventing or delaying the
exercise or transfer of any Warrant.


9.      RESTRICTIONS ON TRANSFERABILITY

        The Warrants and the Warrant Stock shall not be transferred,
hypothecated or assigned before satisfaction of the conditions specified in this
SECTION 9, which conditions are intended to ensure compliance with the
provisions of the Securities Act and state law, with respect to the Transfer of
any Warrant or any Warrant Stock.  Holder, by acceptance of this Warrant, agrees
to be bound by the provisions of this SECTION 9.

        9.1    RESTRICTIVE LEGEND.

               (a)  Except as otherwise provided in this SECTION 9, each
certificate for Warrant Stock initially issued upon the exercise of this
Warrant, and each certificate for Warrant Stock issued to any subsequent
transferee of any such certificate,


                                        13
<PAGE>



shall be stamped or otherwise imprinted with a legend in substantially the
following form:

               "The shares represented by this certificate have not been
        registered under the Securities Act of 1933, as amended, and are subject
        to the conditions specified in a certain Warrant dated as of August ___,
        1995, originally issued by Morrison Knudsen Corporation.  No transfer of
        the shares represented by this certificate shall be valid or effective
        until such conditions and any requirements of federal and state law have
        been fulfilled.  A copy of the form of said Warrant is on file with the
        Secretary of Morrison Knudsen Corporation.  The holder of this
        certificate, by acceptance of this certificate, agrees to be bound by
        the provisions of such Warrant."

               (b)  Except as otherwise provided in this SECTION 9, each
Warrant shall be stamped or otherwise imprinted with a legend in substantially
the following form:

               "This Warrant and the securities represented hereby have not been
        registered under the Securities Act of 1933, as amended, and may not be
        transferred in violation of such Act or state law, the rules and
        regulations thereunder or the provisions of this Warrant."

        9.2    NOTICE OF PROPOSED TRANSFERS; REQUESTS FOR REGISTRATION.  Prior
to any Transfer or attempted Transfer of any Warrants or any shares of
Restricted Common Stock, the holder of such Warrants or Restricted Common Stock
shall give 10 days prior written notice (a "Transfer Notice") to the Company of
such holder's intention to effect such Transfer, describing the manner and
circumstances of the proposed Transfer, and shall deliver to the Company a
certificate of such holder representing and warranting that the proposed
Transfer of such Warrants or such Restricted Common Stock may be effected
without registration under the Securities Act.  After receipt of the Transfer
Notice and certificate, the Company shall, within five days thereof, so notify
the holder of such Warrants or such Restricted Common Stock and such holder
shall thereupon be entitled to Transfer such Warrants or such Restricted Common
Stock, in accordance with the terms of the Transfer Notice.  Each certificate,
if any, evidencing such shares of Restricted Common Stock issued upon such
Transfer shall bear the restrictive legend set forth in SECTION 9.1(a), and
each Warrant issued upon such Transfer shall bear the restrictive legend set
forth in SECTION 9.1(b).  The holder of the Warrants or the Restricted Common
Stock, as the case may be, giving the Transfer Notice shall not be entitled to
transfer and shall not transfer such Warrants or such Restricted Common Stock
until receipt of notice from the Company under this SECTION 9.2(a).


                                        14
<PAGE>



        The holders of Warrants and Warrant Stock shall have the right to
request registration of such Warrant Stock pursuant to and in accordance with
the terms of the Registration Rights Agreement.

        9.3    TERMINATION OF RESTRICTIONS.  Notwithstanding the foregoing
provisions of SECTION 9, the restrictions imposed by this SECTION 9 upon the
transferability of the Warrants, the Warrant Stock and the Restricted Common
Stock (or Common Stock issuable upon the exercise of the Warrants) and the
legend requirements of SECTION 9.1 shall terminate as to any particular
Warrant or share of Warrant Stock or Restricted Common Stock (or Common Stock
issuable upon the exercise of the Warrants) (i) when and so long as such
security shall have been effectively registered under the Securities Act and
disposed of pursuant thereto or (ii) when the Company shall have received an
opinion of counsel reasonably satisfactory to it that such legend is not
required in order to ensure compliance with the Securities Act.  Whenever the
restrictions imposed by this SECTION 9 shall terminate as to this Warrant, as
hereinabove provided, the Holder hereof shall be entitled to receive from the
Company, at the expense of the Company, a new Warrant bearing the following
legend in place of the restrictive legend set forth hereon:

               "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN WARRANT
        CONTAINED IN SECTION 9 HEREOF TERMINATED ON       , 19   , AND ARE
        OF NO FURTHER FORCE AND EFFECT."

All Warrants thereafter issued upon registration of transfer, division or
combination of, or in substitution for, any Warrant or Warrants entitled to bear
such legend shall have a similar legend endorsed thereon.  Whenever the
restrictions imposed by this SECTION 9 shall terminate as to any share of
Restricted Common Stock, as hereinabove provided, the holder thereof shall be
entitled to receive from the Company, at the Company's expense, a new
certificate representing such Common Stock not bearing the restrictive legend
set forth in SECTION 9.1(a).

        9.4    LISTING ON SECURITIES EXCHANGE.  So long as the Company shall
list any shares of Common Stock on any securities exchange, it will, at its
expense, list thereon, maintain and, when necessary, increase such listing of,
all shares of Common Stock issued or, to the extent permissible under the
applicable securities exchange rules, issuable upon the exercise of this
Warrant, so long as any shares of Common Stock shall be so listed during the
Exercise Period.


10.     SUPPLYING INFORMATION

        The Company shall cooperate with each holder of a Warrant or Restricted
Common Stock in supplying such information as may be reasonably necessary for
such holder to complete and file any


                                        15
<PAGE>



information reporting forms presently or hereafter required by the Commission as
a condition to the availability of an exemption from the Securities Act for the
sale of any Warrant or Restricted Common Stock.


11.     LOSS OR MUTILATION

        Upon receipt by the Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity reasonably satisfactory to it, and in
case of mutilation upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder;
PROVIDED, in the case of mutilation, no indemnity shall be required if this
Warrant in identifiable form is surrendered to the Company for cancellation.


12.     OFFICE OF THE COMPANY

        As long as any of the Warrants remain outstanding, the Company shall
maintain an office or agency (which may be the principal executive offices of
the Company) where the Warrants may be presented for exercise, registration of
transfer, division or combination as provided in this Warrant.  The Company
shall notify Holder in writing prior to any change of the address of the office
at which the Warrants may be presented.


13.     FINANCIAL AND BUSINESS INFORMATION

        13.1   FILINGS.  So long as the Company is a "Public Company" (as
hereinafter defined), the Company will file with the Commission on or before the
due date all regular or periodic reports required to be filed pursuant to the
Exchange Act, and will deliver to the Holder, promptly upon its becoming
available, one copy of each report, notice or proxy statement sent by the
Company to its shareholders generally, and one copy of each regular or periodic
report (including, without limitation, reports on Form 8-K) pursuant to the
Exchange Act or any registration statement, prospectus or written communication

available) pursuant to the Securities Act, filed by the Company with (i) the
Commission or (ii) any securities exchange on which shares of the Common Stock
are listed.

               For purposes of this SECTION 13, the term "Public Company"

Section 15(d) of the Exchange Act, or (ii) any of whose securities are
registered pursuant to Section 12(b) or 12(g) of the Exchange Act.



                                        16

the Company, the Company will deliver to the Agent a consolidated balance sheet
of the Company and its consolidated Subsidiaries as of the end of such quarter
and the related consolidated statements of income and cash flows for such
quarter and for the portion of the Company's fiscal year ended at the end of
such quarter, setting forth in the case of such income and cash flows in

fiscal year, all reported on in a manner acceptable to the Commission by
Deloitte & Touche or other independent public accountants of nationally
recognized standing, together with an unaudited annual report prepared on a
consolidating basis in conformity with GAAP.


14.     THE COMPANY'S REPURCHASE OF THE WARRANT

        14.1   OPTION TO REPURCHASE WARRANT.  From time to time on or after
the Initial Exercise Date and until the Expiration Date, the Company shall have
the right, upon not less than thirty (30) days prior written notice to any
Holder, to repurchase from such Holder, from any source of funds legally
available therefor, on the date and in the manner set forth in SECTION 14.2,
all or any part of the Warrant then held by such Holder for an amount
determined by multiplying (x) the number of shares of Common Stock subject to
such Warrant or portion thereof being repurchased, by (y) the difference between
(i) 110% of the higher of the Current Market Price per share of Common Stock and
the Current Warrant Price per share of Common Stock as of the date of such
notice, and (ii) the Current Warrant Price per share of Common Stock as of the
date of such notice; PROVIDED, HOWEVER, that nothing herein shall preclude
the exercise by Holder of any portion of this Warrant exercisable at any time
prior to such repurchase.


                                        17
<PAGE>



        14.2   DETERMINATION AND PAYMENT OF REPURCHASE PRICE.

               (a)  The purchase price for any repurchase pursuant to this
SECTION 14 (the "Repurchase Price") shall be determined within ten (10) days
of the date of the repurchase notice given by the Company pursuant to SECTION
14.1, and shall be payable in cash from any source of funds legally available
therefor within ten (10) days following the date of such determination of the
Repurchase Price.  On the date of any repurchase of this Warrant pursuant to
this SECTION 14, each Holder shall assign to the Company such Holder's Warrant
or portion thereof being repurchased, without any representations (other than a
representation that such Holder owns such Warrant free and clear of any liens,
pledges or encumbrances), by the surrender of such Holder's Warrant at the
principal office of the Company referred to in SECTION 2.1 against payment
therefor of the Repurchase Price by, at the option of such Holder, and subject
to the immediately following sentence, (i) wire transfer to an account in a bank
located in the United States designated by such Holder for such purpose or (ii)
a certified or official bank check drawn on a member of the New York Clearing
House payable to the order of such Holder.  If less than all of any Holder's
Warrant is being repurchased, the Company shall, pursuant to SECTION 3, cancel
such Warrant and issue in the name of, and deliver to, such Holder a new Warrant
for the portion not being repurchased.

               (b)  Each Holder of Warrants shall have the right at any time to
object to the determination of the Repurchase Price pursuant to this SECTION
14 by specifying in writing to the Company the nature of its objection and,
unless such objection is resolved by agreement of the Company and such Holder,
the Company and such Holder shall each have the right to subject the disputed
determination to separate firms of independent accountants of recognized
national standing for a joint resolution of the objection of such Holder (which
firms of independent accountants may, in either case, be the firms of
accountants regularly retained by the Company or such Holder).  If such firms
cannot jointly resolve the objection of such Holder, then, unless otherwise
directed by agreement of the Company and such Holder, such firms shall in their
sole discretion choose another firm of independent certified public accountants
of recognized national standing, which is not the regular auditor of such Holder
or the Company, which firm shall resolve such objection.  In either case, for
purposes hereof the determination so made shall be conclusive and binding on the
Company, such Holder and all Persons claiming under or through any of them, and
any adjustment in the determination of the Repurchase Price per share of Common
Stock resulting from such determination shall be made.  The cost of any such
determination shall be borne by the Company if it results in an increase of the
aggregate Repurchase Price for all shares of Common Stock issuable upon the
exercise hereof and by such Holder if it results in no adjustment or a decrease
of the


                                        18
<PAGE>



aggregate Repurchase Price for all shares of Common Stock issuable upon the
exercise hereof.

               (c)  Any repurchase by the Company of all or any portion of the
Warrant pursuant to SECTION 14.1 which is delayed by (1) the failure of the
Company to determine the Repurchase Price within the time periods required in
SECTION 14.3(a) or (2) an objection by any Holder of the Warrant to any such
determination pursuant to SECTION 14.3(b) shall be consummated within ten (10)
days after, as the case may be, the determination of the Repurchase Price or the
resolution of such objection.

               (d)  In the event that the determination of the Repurchase Price
requires an opinion from an investment banking firm or accounting firm, all
costs and fees associated therewith shall, except to the extent otherwise
provided in SECTION 14.3(b) above, be paid by the Company.

        14.3   PRO RATA REPURCHASE OF WARRANTS.  Notwithstanding anything to
the contrary contained in this SECTION 14, any repurchase by the Company of
this Warrant or any portion thereof shall be made pro rata and on the same terms
with respect to all Warrants and all Metra Warrants then outstanding, and any
obligation of Holder pursuant to this SECTION 14 to sell this Warrant or any
portion thereof to the Company is conditioned upon the Company's compliance with
such requirement.


15.     APPRAISAL

        If required under this Warrant, the determination of the Appraised Value
per share of Common Stock shall be made by an investment banking firm of
nationally recognized standing selected by the Company and acceptable to the
Majority Holders.  If the investment banking firm selected by the Company is not
acceptable to the Majority Holders and the Company and the Majority Holders
cannot agree on a mutually acceptable investment banking firm, then the Majority
Holders and the Company shall each choose one such investment banking firm and
the respective chosen firms shall agree on another investment banking firm which
shall make the determination.  The Company shall retain, at its sole cost, such
investment banking firms as may be necessary for the determination of Appraised
Value required by the terms of this Warrant.


16.     LIMITATION OF LIABILITY

        No provision hereof (including, without limitation, any of the
provisions under Section 7), in the absence of affirmative action by Holder to
purchase shares of Common Stock, and no enumeration herein of the rights or
privileges of Holder hereof, shall give rise to any liability of such Holder for
the purchase price of any Common Stock or as a stockholder of the Company,


                                        19
<PAGE>



whether such liability is asserted by the Company, or by creditors of the
Company.


17.     MISCELLANEOUS

        17.1   NONWAIVER AND EXPENSES.  No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies.
If the Company fails to make, when due, any payments provided for hereunder, or
fails to comply with any other provision of this Warrant, the Company shall pay
to Holder such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys' fees, including those of
appellate proceedings, incurred by Holder in collecting any amounts due pursuant
hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

        17.3   INDEMNIFICATION.  In addition to the indemnities provided in
the Registration Rights Agreement, the Company agrees to indemnify and hold
harmless Holder, its officers, directors, employees, agents, and attorneys from
and against any liabilities, obligations, losses, damages, penalties, actions,

any kind which may be imposed upon, incurred by or asserted against Holder
relating to or arising out of (i) Holder's exercise of this Warrant and/or
ownership of any shares of Warrant Stock issued in consequence thereof, or (ii)
any litigation to which Holder is made a party in its capacity as a stockholder
or warrant holder of the Company; PROVIDED, HOWEVER, that the Company will
not be liable hereunder to the extent that any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs, attorneys' fees,
expenses or disbursements are found in a final non-appealable judgment by a

misconduct, (ii) actions or omissions taken or not taken by Holder in any
capacity other than as a stockholder or warrant holder of the Company, or (iii)
any violation of federal or state securities laws by Holder, which is not caused
by any action or inaction of the Company.

        17.4   REMEDIES.  Each holder of Warrants and Warrant Stock, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under SECTIONS 9, 10, 13 AND 14 of this Warrant.  Each party agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of SECTION 9, 10, 13 OR 14 of this
Warrant and hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

        17.5   SUCCESSORS AND ASSIGNS.  Subject to the provisions of SECTIONS
3.1 AND 9, this Warrant and the rights evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and assigns of Holder.  The provisions of this Warrant are intended to be for
the benefit of all Holders from time to time of this Warrant, and shall be
enforceable by any such Holder.

        17.6   AMENDMENT.  This Warrant and all other Warrants may be modified
or amended or the provisions hereof waived with the written consent of the
Company and the Majority Holders; PROVIDED, HOWEVER, that no such Warrant
may be modified or amended to reduce the number of shares of Common Stock for
which such Warrant is exercisable (including, without limitation, by way of
amendment of SECTION 4.1), to increase the price at which such shares may be
purchased upon exercise of such Warrant (before giving effect to any adjustment
as provided therein), or to modify the time period during which such Warrant may
be exercised, without the prior written consent of the Holder thereof; AND
PROVIDED FURTHER, that no such Warrant may be modified or amended unless the
"Majority Holders" as defined under the Metra Warrant have agreed to the same
modification or amendment of the Metra Warrant.

        17.7   SEVERABILITY.  Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.

        17.8   HEADINGS.  The headings used in this Warrant are for the

number of shares of Common Stock to be purchased; (b) payment of the Warrant
Price in the manner specified below; and (c) this Warrant.  Such notice shall be
substantially in the form of the subscription form appearing at the end of this
Warrant as EXHIBIT A, duly executed by Holder or its agent or attorney.
Upon receipt thereof, the Company shall, as promptly as practicable, and in any
event within five (5) Business Days thereafter, execute and deliver to Holder a
certificate or certificates representing the aggregate number of shares of
Common Stock issuable upon such exercise.  The stock certificate or certificates
so delivered shall be, to the extent possible, in such denomination or
denominations as such Holder shall request in the notice and shall be registered
in the name of Holder or, subject to SECTION 9, such other names as shall be
designated in the notice.  This Warrant shall be deemed to have been exercised
and such certificate or certificates of Common Stock shall be deemed to have
been issued, and Holder or any other Person so designated to be named therein
shall be deemed to have become a holder of record of such shares for all
purposes, as of the date the notice, together with the payment as set forth
below, and this Warrant are received by the Company as described above and all
taxes, if any, required to be paid by Holder pursuant to SECTION 2.2 prior to
the issuance of such shares of Common Stock, have been paid or Holder has agreed
to pay such taxes when finally determined.  If this Warrant shall have been
exercised in part, the Company shall, at the time of delivery of the certificate
or certificates representing Warrant Stock, deliver to Holder a new Warrant
evidencing the rights of Holder to purchase the unpurchased shares of Common
Stock called for by this Warrant, which new Warrant shall in all other respects
be


                                        6

<PAGE>

identical with this Warrant, or, at the request of Holder, appropriate notation
may be made on this Warrant and the same returned to Holder.  Notwithstanding
any provision herein to the contrary, the Company shall not be required to
register shares of Warrant Stock in the name of any Person who acquired this
Warrant (or part hereof) or any Warrant Stock otherwise than in accordance with
this Warrant.

               Payment of the Warrant Price shall be made at the option of the
Holder (i) by certified or official bank check payable to the order of the
Company, (ii) by cancellation of indebtedness, if any, owed by the Company to
such Holder, (iii) by receiving from the Company the number of shares of Common
Stock equal to (x) the number of shares of Common Stock as to which this Warrant
is being exercised, MINUS (y) the number of shares of Common Stock having a
value, based on the Current Market Price on the date of such exercise, equal to
the Warrant Price, or (iv) by a combination thereof.

        2.2    PAYMENT OF TAXES.  All shares of Common Stock issuable upon the
exercise of this Warrant pursuant to the terms hereof shall be validly issued,
fully paid, nonassessable, free of liens or encumbrances (except for the
restrictive legend provided for herein) and without any preemptive rights.  The
Company shall pay all expenses in connection with, and all taxes and other
governmental charges that may be imposed with respect to, the issue of the
Common Stock hereunder, unless such tax or charge is imposed by law upon Holder,
in which case such taxes or charges shall be paid by Holder.  The Company shall
not be required, however, to pay any tax or other charge imposed in connection
with any transfer involved in the issue of any certificate for shares of Common
Stock issuable upon exercise of this Warrant in any name other than that of
Holder, and in such case the Company shall not be required to issue or deliver
any stock certificate until such tax or other charge has been paid or the Person
designated to receive such shares has agreed in writing to pay such tax or
charge or it has been established to the satisfaction of the Company that no
such tax or other charge is due.

        2.3    CONTINUED VALIDITY.  A holder of shares of Common Stock issued
upon the exercise of this Warrant, in whole or in part (other than a holder who
acquires such shares after the same have been publicly sold pursuant to a
Registration Statement under the Securities Act or sold pursuant to Rule 144
thereunder), shall continue to be entitled with respect to such shares to all
rights to which it would have been entitled as Holder under SECTIONS 9, 10, 13,
14 and 17 of this Warrant.  The Company will, at the time of each exercise of
this Warrant, in whole or in part, upon the request of the holder of the shares
of Common Stock issued upon such exercise hereof, acknowledge in writing, in
form reasonably satisfactory to such holder, its continuing obligation to afford
to such holder all such rights; PROVIDED, HOWEVER, that if such holder shall
fail to make any


                                        7

<PAGE>

such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder all such rights.


3.      TRANSFER, DIVISION AND COMBINATION

        3.1    TRANSFER.  Subject to compliance with SECTIONS 9 AND 14,
transfer of this Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the principal office of the Company referred to in
SECTION 2.1 or the office or agency designated by the Company pursuant to
SECTION 12, together with a written assignment of this Warrant substantially
in the form of EXHIBIT B hereto duly executed by Holder or its agent or
attorney and if such transfer is not to be made pursuant to SECTION 14, funds
sufficient to pay any transfer taxes payable upon the making of such transfer.
Upon such surrender and, if required, such payment, the Company shall, subject
to SECTION 9, execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be canceled.  A
Warrant, if properly assigned in compliance with SECTION 9, may be exercised
by a new Holder for the purchase of shares of Common Stock without having a new
Warrant issued.  If requested by the Company, a new Holder shall acknowledge in
writing, in form reasonably satisfactory to the Company, such Holder's
continuing obligations under SECTIONS 9 AND 14 of this Warrant.

        3.2    DIVISION AND COMBINATION.  Subject to SECTION 9, this Warrant
may be divided or combined with other Warrants upon presentation hereof at the
aforesaid office or agency of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by Holder or its agent or attorney.  Subject to compliance with SECTION
3.1 and with SECTION 9, as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

        3.3    EXPENSES.  The Company shall prepare, issue and deliver at its
own expense (other than transfer taxes) the new Warrant or Warrants under this
SECTION 3.

        3.4    MAINTENANCE OF BOOKS.  The Company agrees to maintain, at its
aforesaid office or agency, books for the registration, and the registration of
transfer, of the Warrants.

4.      ADJUSTMENTS

        The number of shares of Common Stock for which this Warrant is
exercisable, or the price at which such shares may be purchased upon exercise of
this Warrant, shall be subject to adjustment from time to time as set forth in
this SECTION 4.  The Company shall give each Holder notice of any event
described below which requires an adjustment pursuant to this SECTION 4 at the
time of such event.

        4.1    PREPAYMENT OF OBLIGATIONS UNDER OVERRIDE AGREEMENT.  If the
Repayment Event occurs on or prior to the earlier of the Initial Exercise Date
and September 30, 1996, then the number of shares of Common Stock for which this
Warrant is exercisable immediately after the occurrence of such event shall be
adjusted as follows:


- -------------------------------------------------------------------------------
If the Repayment Event occurs          Then the number of shares of
during the following period            Common Stock for which this
                                       Warrant is exercisable
                                       immediately prior
                                       to such event is reduced by
- -------------------------------------------------------------------------------
Closing Date through June 30,          100%
1996
- -------------------------------------------------------------------------------
July 1, 1996 through                   50%
December 31, 1996
- -------------------------------------------------------------------------------
- -------------------------------------------------------------------------------
January 1, 1997 through                25%
June 30, 1997
- -------------------------------------------------------------------------------
- -------------------------------------------------------------------------------

        4.2    STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any time
the Company shall:

               (a)  take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, Additional Shares of Common Stock;

               (b)  subdivide its outstanding shares of Common Stock into a
larger number of shares of Common Stock, or

               (c)  combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock,

then (i) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (ii) the Current Warrant Price
shall be adjusted to equal (A) the Current Warrant


                                        9

<PAGE>

Price in effect immediately prior to the occurrence of such event, multiplied by
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the adjustment divided by (B) the number of shares for
which this Warrant is exercisable immediately after such adjustment.

        4.3    OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION.
The following provisions shall be applicable to the making of adjustments
pursuant to this SECTION 4, of the number of shares of Common Stock for which
this Warrant is exercisable:

               (a)  WHEN ADJUSTMENTS TO BE MADE.  The adjustments required by
this SECTION 4 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment of the number of
shares of Common Stock for which this Warrant is exercisable that would
otherwise be required may be postponed (except in the case of an adjustment
pursuant to SECTION 4.1 or a subdivision or combination of shares of the
Common Stock, as provided for in SECTION 4.2) up to, but not beyond the date
of exercise of this Warrant (or date of repurchase by the Company under SECTION
14) if such adjustment either by itself or with other adjustments not
previously made adds or subtracts less than one percent (1%) of the shares of
Common Stock for which this Warrant is exercisable immediately prior to the
making of such adjustment.  Any adjustment representing a change of less than
such minimum amount (except as aforesaid) which is postponed shall be carried
forward and made as soon as such adjustment, together with other adjustments
required by this SECTION 4 and not previously made, would result in a minimum
adjustment or on the date of exercise or repurchase.  For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close of
business on the date of its occurrence.

               (b)  FRACTIONAL INTERESTS.  In computing adjustments under this
SECTION 4, fractional interests in Common Stock shall be taken into account to
the nearest 1/10th of a share.

               (c)  WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver
such dividend or distribution, then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made
in respect thereof shall be rescinded and annulled.

        4.4    REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation), or sell,
transfer or


                                        10

<PAGE>

otherwise dispose of all or substantially all its property, assets or business
to another corporation and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation or disposition of assets, shares of
common stock of the successor or acquiring corporation, or any cash, shares of
stock or other securities or property of any nature whatsoever (including
warrants or other subscription or purchase rights) in addition to or in lieu of
common stock of the successor or acquiring corporation ("Other Property"), are
to be received by or distributed to the holders of Common Stock of the Company,
then each Holder shall have the right thereafter to receive, upon exercise of
such Holder's Warrant, the number of shares of common stock of the successor or
acquiring corporation and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event.  In case of any such
reorganization, reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation shall expressly assume the due
and punctual observance and performance of each and every covenant and condition
of this Warrant to be performed and observed by the Company and all the
obligations and liabilities hereunder, subject to such modifications as may be
deemed appropriate (as determined by resolution of the Board of Directors of the
Company) in order to provide for adjustments of the shares of Common Stock for
which this Warrant is exercisable, which adjustments shall be as nearly
equivalent as practicable to the adjustments provided for in this SECTION 4.
For purposes of this SECTION 4.4, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or rights on liquidation over any other class of stock
of such corporation and which is not subject to redemption and shall also
include any evidences of indebtedness, shares of stock or other securities which
are convertible into or exchangeable for any such stock, either immediately or
upon a specified date or the happening of a specified event and any warrants or
other rights to subscribe for or purchase any such stock.  The foregoing
provisions of this SECTION 4.4 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or dispositions of
assets.


5.      NOTICES TO WARRANT HOLDERS

        5.1    NOTICE OF ADJUSTMENTS.  Whenever the number of shares of Common
Stock for which this Warrant is exercisable, or whenever the price at which a
share of such Common Stock may be purchased upon exercise of the Warrants, shall
be adjusted pursuant to SECTION 4, the Company shall forthwith prepare a
certificate to be executed by the chief financial officer of the Company setting
forth, in reasonable detail, the event requiring the adjustment and the method
by which such adjustment was


                                        11

<PAGE>

calculated, specifying the number of shares of Common Stock for which this
Warrant is exercisable and (if such adjustment was made pursuant to SECTION
4.4) describing the number and kind of any other shares of stock or Other
Property for which this Warrant is exercisable, and any change in the purchase
price or prices thereof, after giving effect to such adjustment or change.  The
Company shall promptly cause a signed copy of such certificate to be delivered
to each Holder in accordance with SECTION 17.2.  The Company shall keep at its
office or agency designated pursuant to SECTION 12 copies of all such
certificates and cause the same to be available for inspection at said office
during normal business hours by any Holder or any prospective purchaser of a
Warrant designated by a Holder thereof.

        5.2    NOTICE OF CERTAIN CORPORATE ACTION.  The Holder shall be
entitled to the same rights to receive notice of corporate action as any holder
of Common Stock.


6.      NO IMPAIRMENT

        The Company shall not by any action avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms.  Without
limiting the generality of the foregoing, the Company will (a) not increase the
par value of any shares of Common Stock receivable upon the exercise of this
Warrant above the amount payable therefor upon such exercise immediately prior
to such increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock, upon the exercise of this Warrant, and
(c) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

        Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form reasonably
satisfactory to Holder, the continuing validity of this Warrant and the
obligations of the Company hereunder.


7.      RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR
        APPROVAL OF ANY GOVERNMENTAL AUTHORITY; PREFERRED STOCK

        From and after the Closing Date, the Company shall at all times reserve
and keep available for issuance upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants.  All shares of Common Stock
which shall be so issuable, when issued upon exercise of any Warrant


                                        12

<PAGE>

and payment therefor in accordance with the terms of such Warrant, shall be duly
and validly issued and fully paid and nonassessable, and not subject to
preemptive rights.

        Before taking any action which would cause an adjustment reducing the
Current Warrant Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and nonassessable shares of such Common Stock at
such adjusted Current Warrant Price.

        Before taking any action which would result in an adjustment in the
number of shares of Common Stock for which this Warrant is exercisable or in the
Current Warrant Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

        If any shares of Common Stock required to be reserved for issuance upon
exercise of Warrants require registration or qualification with any governmental
authority under any federal or state law (otherwise than as provided in SECTION
9) before such shares may be so issued, the Company will in good faith and as
expeditiously as possible and at its expense endeavor to cause such shares to be
duly registered or qualified.


8.      TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

        In the case of all dividends or other distributions by the Company to
the holders of its Common Stock with respect to which any provision of SECTION
4 refers to the taking of a record of such holders, the Company will in each
such case take such a record and will take such record as of the close of
business on a Business Day.  The Company will not at any time, except upon
dissolution, liquidation or winding up of the Company, close its stock transfer
books or Warrant transfer books so as to result in preventing or delaying the
exercise or transfer of any Warrant.


9.      RESTRICTIONS ON TRANSFERABILITY

        The Warrants and the Warrant Stock shall not be transferred,
hypothecated or assigned before satisfaction of the conditions specified in this
SECTION 9, which conditions are intended to ensure compliance with the
provisions of the Securities Act and state law, with respect to the Transfer of
any Warrant or any Warrant Stock.  Holder, by acceptance of this Warrant, agrees
to be bound by the provisions of this SECTION 9.


                                        13

<PAGE>

        9.1    RESTRICTIVE LEGEND.

               (a)  Except as otherwise provided in this SECTION 9, each
certificate for Warrant Stock initially issued upon the exercise of this
Warrant, and each certificate for Warrant Stock issued to any subsequent
transferee of any such certificate, shall be stamped or otherwise imprinted with
a legend in substantially the following form:

               "The shares represented by this certificate have not been
        registered under the Securities Act of 1933, as amended, and are
        subject to the conditions specified in a certain Warrant dated
        as of August ___, 1995, originally issued by Morrison Knudsen
        Corporation.  No transfer of the shares represented by this
        certificate shall be valid or effective  until such conditions
        and any requirements of federal and state law have been fulfilled.
        A copy of the form of said Warrant is on file with the Secretary
        of Morrison Knudsen Corporation.  The holder of this certificate,
        by acceptance of this certificate, agrees to be bound by the provisions
        of such Warrant."

               (b)  Except as otherwise provided in this SECTION 9, each
Warrant shall be stamped or otherwise imprinted with a legend in substantially
the following form:

               "This Warrant and the securities represented hereby have
        not been registered under the Securities Act of 1933, as
        amended, and may not be transferred in violation of such Act or
        state law, the rules and regulations thereunder or the
        provisions of this Warrant."

        9.2    NOTICE OF PROPOSED TRANSFERS; REQUESTS FOR REGISTRATION.  Prior
to any Transfer or attempted Transfer of any Warrants or any shares of
Restricted Common Stock, the holder of such Warrants or Restricted Common Stock
shall give 10 days prior written notice (a "Transfer Notice") to the Company of
such holder's intention to effect such Transfer, describing the manner and
circumstances of the proposed Transfer, and shall deliver to the Company a
certificate of such holder representing and warranting that the proposed
Transfer of such Warrants or such Restricted Common Stock may be effected
without registration under the Securities Act.  After receipt of the Transfer
Notice and certificate, the Company shall, within five days thereof, so notify
the holder of such Warrants or such Restricted Common Stock and such holder
shall thereupon be entitled to Transfer such Warrants or such Restricted Common
Stock, in accordance with the terms of the Transfer Notice.  Each certificate,
if any, evidencing such shares of Restricted Common Stock issued upon such
Transfer shall bear the restrictive legend set forth in SECTION 9.1(a), and
each Warrant issued upon such Transfer shall


                                        14

<PAGE>

bear the restrictive legend set forth in SECTION 9.1(b).  The holder of the
Warrants or the Restricted Common Stock, as the case may be, giving the Transfer
Notice shall not be entitled to transfer and shall not transfer such Warrants or
such Restricted Common Stock until receipt of notice from the Company under this
SECTION 9.2(a).

        The holders of Warrants and Warrant Stock shall have the right to
request registration of such Warrant Stock pursuant to and in accordance with
the terms of the Registration Rights Agreement.

        9.3    TERMINATION OF RESTRICTIONS.  Notwithstanding the foregoing
provisions of SECTION 9, the restrictions imposed by this SECTION 9 upon the
transferability of the Warrants, the Warrant Stock and the Restricted Common
Stock (or Common Stock issuable upon the exercise of the Warrants) and the
legend requirements of SECTION 9.1 shall terminate as to any particular
Warrant or share of Warrant Stock or Restricted Common Stock (or Common Stock
issuable upon the exercise of the Warrants) (i) when and so long as such
security shall have been effectively registered under the Securities Act and
disposed of pursuant thereto or (ii) when the Company shall have received an
opinion of counsel reasonably satisfactory to it that such legend is not
required in order to ensure compliance with the Securities Act.  Whenever the
restrictions imposed by this SECTION 9 shall terminate as to this Warrant, as
hereinabove provided, the Holder hereof shall be entitled to receive from the
Company, at the expense of the Company, a new Warrant bearing the following
legend in place of the restrictive legend set forth hereon:

               "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN WARRANT
        CONTAINED IN SECTION 9 HEREOF TERMINATED ON ___________________, 19___,
        AND ARE OF NO FURTHER FORCE AND EFFECT."

All Warrants thereafter issued upon registration of transfer, division or
combination of, or in substitution for, any Warrant or Warrants entitled to bear
such legend shall have a similar legend endorsed thereon.  Whenever the
restrictions imposed by this SECTION 9 shall terminate as to any share of
Restricted Common Stock, as hereinabove provided, the holder thereof shall be
entitled to receive from the Company, at the Company's expense, a new
certificate representing such Common Stock not bearing the restrictive legend
set forth in SECTION 9.1(a).

        9.4    LISTING ON SECURITIES EXCHANGE.  So long as the Company shall
list any shares of Common Stock on any securities exchange, it will, at its
expense, list thereon, maintain and, when necessary, increase such listing of,
all shares of Common Stock issued or, to the extent permissible under the
applicable securities exchange rules, issuable upon the exercise of this
Warrant, so long as any shares of Common Stock shall be so listed during the
Exercise Period.

<PAGE>

10.     SUPPLYING INFORMATION

        The Company shall cooperate with each holder of a Warrant or Restricted
Common Stock in supplying such information as may be reasonably necessary for
such holder to complete and file any information reporting forms presently or
hereafter required by the Commission as a condition to the availability of an
exemption from the Securities Act for the sale of any Warrant or Restricted
Common Stock.


11.     LOSS OR MUTILATION

        Upon receipt by the Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity reasonably satisfactory to it, and in
case of mutilation upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder;
PROVIDED, in the case of mutilation, no indemnity shall be required if this
Warrant in identifiable form is surrendered to the Company for cancellation.


12.     OFFICE OF THE COMPANY

        As long as any of the Warrants remain outstanding, the Company shall
maintain an office or agency (which may be the principal executive offices of
the Company) where the Warrants may be presented for exercise, registration of
transfer, division or combination as provided in this Warrant.  The Company
shall notify Holder in writing prior to any change of the address of the office
at which the Warrants may be presented.


13.     FINANCIAL AND BUSINESS INFORMATION

        13.1   FILINGS.  So long as the Company is a "Public Company" (as
hereinafter defined), the Company will file with the Commission on or before the
due date all regular or periodic reports required to be filed pursuant to the
Exchange Act, and will deliver to the Holder, promptly upon its becoming
available, one copy of each report, notice or proxy statement sent by the
Company to its shareholders generally, and one copy of each regular or periodic
report (including, without limitation, reports on Form 8-K) pursuant to the
Exchange Act or any registration statement, prospectus or written communication
(other than transmittal letters and other communications that are not publicly
available) pursuant to the Securities Act, filed by the Company with (i) the
Commission or (ii) any securities exchange on which shares of the Common Stock
are listed.

<PAGE>

               For purposes of this SECTION 13, the term "Public Company"
shall mean a company (i) that is subject to the reporting requirements
of Section 15(d) of the Exchange Act, or (ii) any of whose securities are
registered pursuant to Section 12(b) or 12(g) of the Exchange Act.

        13.2   QUARTERLY INFORMATION.  During any period in which the Company
is not a Public Company, as soon as available and in any event within 45 days
after the end of each of the first three fiscal quarters of each fiscal year of
the Company, the Company will deliver to the Agent a consolidated balance sheet
of the Company and its consolidated Subsidiaries as of the end of such quarter
and the related consolidated statements of income and cash flows for such
quarter and for the portion of the Company's fiscal year ended at the end of
such quarter, setting forth in the case of such income and cash flows in
comparative form the figures for the corresponding quarter and the corresponding
portion of the Company's previous fiscal year, all certified (subject to normal
year-end adjustments) as to fairness of presentation, GAAP, and consistency by
the chief financial officer, controller or treasurer of the Company.

        13.3   ANNUAL INFORMATION.  During any period in which the Company is
not a Public Company, as soon as available and in any event within 90 days after
the end of each fiscal year of the Company, the Company will deliver to the
Agent a consolidated balance sheet of the Company and its consolidated
Subsidiaries as of the end of such fiscal year and the related consolidated
statements of income, retained earnings and cash flows for such fiscal year,
setting forth in each case in comparative form the figures for the previous
fiscal year, all reported on in a manner acceptable to the Commission by
Deloitte & Touche or other independent public accountants of nationally
recognized standing, together with an unaudited annual report prepared on a
consolidating basis in conformity with GAAP.


14.     THE COMPANY'S REPURCHASE OF THE WARRANT

        14.1   OPTION TO REPURCHASE WARRANT.  From time to time on or after
the Initial Exercise Date and until the Expiration Date, the Company shall have
the right, upon not less than thirty (30) days prior written notice to any
Holder, to repurchase from such Holder, from any source of funds legally
available therefor, on the date and in the manner set forth in SECTION 14.2,
all or any part of the Warrant then held by such Holder for an amount
determined by multiplying (x) the number of shares of Common Stock subject to
such Warrant or portion thereof being repurchased, by (y) the difference between
(i) 110% of the higher of the Current Market Price per share of Common Stock and
the Current Warrant Price per share of Common Stock as of the date of such
notice, and (ii) the Current Warrant Price per share of Common Stock as of the
date of such notice; PROVIDED, HOWEVER, that nothing herein shall preclude
the exercise by Holder of any


                                        17

<PAGE>

portion of this Warrant exercisable at any time prior to such repurchase.

        14.2   DETERMINATION AND PAYMENT OF REPURCHASE PRICE.

               (a)  The purchase price for any repurchase pursuant to this
SECTION 14 (the "Repurchase Price") shall be determined within ten (10) days
of the date of the repurchase notice given by the Company pursuant to SECTION
14.1, and shall be payable in cash from any source of funds legally available
therefor within ten (10) days following the date of such determination of the
Repurchase Price.  On the date of any repurchase of this Warrant pursuant to
this SECTION 14, each Holder shall assign to the Company such Holder's Warrant
or portion thereof being repurchased, without any representations (other than a
representation that such Holder owns such Warrant free and clear of any liens,
pledges or encumbrances), by the surrender of such Holder's Warrant at the
principal office of the Company referred to in SECTION 2.1 against payment
therefor of the Repurchase Price by, at the option of such Holder, and subject
to the immediately following sentence, (i) wire transfer to an account in a bank
located in the United States designated by such Holder for such purpose or (ii)
a certified or official bank check drawn on a member of the New York Clearing
House payable to the order of such Holder.  If less than all of any Holder's
Warrant is being repurchased, the Company shall, pursuant to SECTION 3, cancel
such Warrant and issue in the name of, and deliver to, such Holder a new Warrant
for the portion not being repurchased.

               (b)  Each Holder of Warrants shall have the right at any time to
object to the determination of the Repurchase Price pursuant to this SECTION
14 by specifying in writing to the Company the nature of its objection and,
unless such objection is resolved by agreement of the Company and such Holder,
the Company and such Holder shall each have the right to subject the disputed
determination to separate firms of independent accountants of recognized
national standing for a joint resolution of the objection of such Holder (which
firms of independent accountants may, in either case, be the firms of
accountants regularly retained by the Company or such Holder).  If such firms
cannot jointly resolve the objection of such Holder, then, unless otherwise
directed by agreement of the Company and such Holder, such firms shall in their
sole discretion choose another firm of independent certified public accountants
of recognized national standing, which is not the regular auditor of such Holder
or the Company, which firm shall resolve such objection.  In either case, for
purposes hereof the determination so made shall be conclusive and binding on the
Company, such Holder and all Persons claiming under or through any of them, and
any adjustment in the determination of the Repurchase Price per share of Common
Stock resulting from such determination shall be made.  The cost of any such
determination shall be borne by the Company if it results in an increase of the
aggregate Repurchase Price for all shares of Common Stock issuable upon the
exercise hereof and by



                                        18

<PAGE>

such Holder if it results in no adjustment or a decrease of the aggregate
Repurchase Price for all shares of Common Stock issuable upon the exercise
hereof.

               (c)  Any repurchase by the Company of all or any portion of the
Warrant pursuant to SECTION 14.1 which is delayed by (1) the failure of the
Company to determine the Repurchase Price within the time periods required in
SECTION 14.3(a) or (2) an objection by any Holder of the Warrant to any such
determination pursuant to SECTION 14.3(b) shall be consummated within ten (10)
days after, as the case may be, the determination of the Repurchase Price or the
resolution of such objection.

               (d)  In the event that the determination of the Repurchase Price
requires an opinion from an investment banking firm or accounting firm, all
costs and fees associated therewith shall, except to the extent otherwise
provided in SECTION 14.3(b) above, be paid by the Company.

        14.3   PRO RATA REPURCHASE OF WARRANTS.  Notwithstanding anything to
the contrary contained in this SECTION 14, any repurchase by the Company of
this Warrant or any portion thereof shall be made pro rata and on the same terms
with respect to all Warrants and all Antecedent Debt Warrants then outstanding,
and any obligation of Holder pursuant to this SECTION 14 to sell this Warrant
or any portion thereof to the Company is conditioned upon the Company's
compliance with such requirement.


15.     APPRAISAL

        If required under this Warrant, the determination of the Appraised Value
per share of Common Stock shall be made by an investment banking firm of
nationally recognized standing selected by the Company and acceptable to the
Majority Holders.  If the investment banking firm selected by the Company is not
acceptable to the Majority Holders and the Company and the Majority Holders
cannot agree on a mutually acceptable investment banking firm, then the Majority
Holders and the Company shall each choose one such investment banking firm and
the respective chosen firms shall agree on another investment banking firm which
shall make the determination.  The Company shall retain, at its sole cost, such
investment banking firms as may be necessary for the determination of Appraised
Value required by the terms of this Warrant.


16.     LIMITATION OF LIABILITY

        No provision hereof (including, without limitation, any of the
provisions under Section 7), in the absence of affirmative action by Holder to
purchase shares of Common Stock, and no enumeration herein of the rights or
privileges of Holder hereof, shall give rise to any liability of such Holder for
the purchase


                                        19

<PAGE>

price of any Common Stock or as a stockholder of the Company, whether such
liability is asserted by the Company, or by creditors of the Company.


17.     MISCELLANEOUS

        17.1   NONWAIVER AND EXPENSES.  No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies.
If the Company fails to make, when due, any payments provided for hereunder, or
fails to comply with any other provision of this Warrant, the Company shall pay
to Holder such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys' fees, including those of
appellate proceedings, incurred by Holder in collecting any amounts due pursuant
hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights

monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of SECTION 9, 10, 13 OR 14 of this
Warrant and hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

        17.5   SUCCESSORS AND ASSIGNS.  Subject to the provisions of SECTIONS
3.1 and 9, this Warrant and the rights evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors

enforceable by any such Holder.

may be modified or amended to reduce the number of shares of Common Stock for

amendment of SECTION 4.1), to increase the price at which such shares may be
purchased upon exercise of such Warrant (before giving effect to any adjustment
as provided therein), or to modify the time period during which such Warrant may

PROVIDED FURTHER, that no such Warrant may be modified or amended unless the
"Majority Holders" as defined under the Antecedent Debt Warrant have agreed to
the same modification or amendment of the Antecedent Debt Warrant.

        17.7   SEVERABILITY.  Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under

of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.

                                  RECITALS

           WHEREAS, the Company and Morrison Knudsen Corporation, an Ohio

Purchasers and certain other banks and other financial institutions (each an

subscribe for and purchase from the Company, and the Company agrees to authorize
as necessary and to sell and issue to such Purchaser a Warrant to purchase
shares of the Company's Common Stock in accordance with such Purchaser's Warrant
Allocation, in consideration of, among other things, such Purchaser's agreement
to enter into the Override Agreement.  The Warrants and the Warrant Stock (as

into separate Warrants for each individual Purchaser thereof, (ii) the Company
will deliver to the Agent such separate Warrants in exchange for the single
Antecedent Debt Warrant, (iii) the single Metra Warrant will be divided in

separate Warrants, the Agent shall deliver each of them to the respective
Purchasers thereof.

           2.3   ORIGINAL ISSUE DISCOUNT.  The Company and each Purchaser
hereby acknowledge and agree that there is no original issue discount with
respect to the Warrants and, for all tax and accounting purposes, each of them
shall treat the Warrants in such manner.

      3.   EACH PURCHASER'S REPRESENTATIONS AND WARRANTIES

           Each Purchaser makes the following representations and warranties to
the Company, each and all of which shall survive the execution and delivery of
this Agreement and the Closing:

           3.1   INVESTMENT REPRESENTATIONS.  Such Purchaser is purchasing
the Securities for its own account and not with a view to the distribution
thereof.  Such Purchaser agrees that it will not, directly or indirectly, offer,

Securities (or solicit any offers to buy, purchase, or otherwise acquire or take
a pledge of any of the Securities), except in compliance with the Securities Act
of 1933, as amended (the "Securities Act") and the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and the rules and regulations under the

           Such Purchaser (a) is an institutional "accredited investor" within

had an opportunity to investigate the business and financial condition of the
Company, and to obtain such information as it requires from the officers and

in financial and business matters that it is capable of evaluating the merits
and risks of purchasing the Securities; (d) is aware that it may be required to
bear the

economic risk of an investment in the Securities for an indefinite period of
time and is able to bear such risk for an indefinite period of time; and (e) is
not purchasing any Securities on behalf of any managed accounts.

      4.   COMPANY'S REPRESENTATIONS AND WARRANTIES

           The Company makes the following representations and warranties to
the Agent and each Purchaser, each and all of which shall survive the execution
and delivery of this Agreement and the Closing; provided the Company shall not
be required to make any representation or warranty under Section 4.2 with
respect to any matters arising from or in connection with its application to the
New York Stock Exchange, until the Closing:

           4.1   AUTHORIZED AND OUTSTANDING SHARES OF CAPITAL STOCK.  After
giving effect to the Closing, the authorized capital stock of the Company
consists of 100,000,000 shares of Common Stock, par value One Dollar and
Sixty-Six and Two-Thirds Cents ($1.66-2/3) per share, of which 33,490,664 shares
are issued and outstanding, and 10,000,000 shares of Preferred Stock, par value
Ten Cents (10CENTS) per share, none of which shares are issued and outstanding.
Except for the Securities and the commitments, warrants, options, or other
matters described in EXHIBIT B hereto, after giving effect to the Closing and
as of the date hereof, there is no commitment, contingent or otherwise, of the
Company to issue any shares of any class of capital stock of the Company or any
securities convertible into such capital stock, warrants, options or other such
rights or securities.

           4.2   AUTHORIZATION OF AGREEMENT AND ISSUANCE OF SECURITIES.  The
Company is authorized to enter into this Agreement, to perform its obligations
hereunder and to consummate the transactions contemplated hereby, including the
issuance of the Warrants.  Upon delivery of the Warrants to the Agent, the
Warrants will have been duly executed and issued and, when delivered in exchange
for the consideration set forth in SECTION 2.1, will constitute the legal,
valid and binding obligation of the Company, enforceable in accordance with its
terms.  The issuance of the Warrant Stock has been duly authorized and, when
issued upon exercise of, and pursuant to, the Warrants, will have been validly
issued and will be fully paid and non-assessable, free and clear of all pledges,
liens, encumbrances and preemptive rights.  14,029,391 shares of Common Stock
have been duly reserved for issuance pursuant to the Warrants.

           4.3   SECURITIES LAWS.  In reliance on, among other things, the
investment representations contained in SECTION 3.1, the offer, issuance, sale
and delivery of the Warrants as provided in this Agreement, and the offer,

Purchaser

registration requirements of Section 5 of the Securities Act and all applicable
state securities laws.

      5.   COVENANTS

           The Company covenants and agrees that from and after the date hereof
(except as otherwise provided herein, or unless Purchasers then holding the
beneficial interest in at least sixty-six and two-thirds percent (66-2/3%) of
the Securities (the "Required Purchasers") have given their prior written
consent), so long as any Purchaser is the beneficial holder of any Securities:

           5.1   BOOKS AND RECORDS.  The Company shall keep adequate records
and books of account with respect to its business activities in which proper
entries, reflecting all of its financial transactions, are made in accordance

Agent or its officers, employees, and/or agents, during normal business hours
(or at such other times as may reasonably be requested by the Agent), as
frequently as the Agent deems appropriate, to inspect such records and books of
account and the properties and facilities of the Company, and the Company shall
provide extracts and/or photocopies of such records and books of account as
reasonably requested by the Agent at no cost to the Agent.  The rights set forth
in this SECTION 5.1 shall not negate any other rights that the Agent may have
under any applicable law.

           5.2   FINANCIAL AND BUSINESS INFORMATION.

                 (a)   FILINGS.  So long as the Company is a "Public Company"

communications that are not publicly available) pursuant to the Securities Act,
filed by the Company with (i) the Commission or (ii) any securities exchange on
which shares of the Common Stock are listed.  For purposes of this SECTION

consolidating basis in conformity with Generally Accepted Accounting Principles.

           5.3   TAX COMPLIANCE.  The Company shall pay all transfer, excise
or similar taxes (not including income or franchise taxes) in connection with
the issuance, sale, delivery or transfer by the Company to the Agent or any
Purchaser of the Securities and shall save the Agent, each Purchaser, and any
other holder of the Securities harmless without limitation as to time against
any and all liabilities with respect to such taxes.  The Company shall not be

opinions in the forms attached as EXHIBIT D hereto.

      6.   CONDITIONS PRECEDENT

<PAGE>

of each of the conditions precedent set forth in Article V of the Override

Purchaser shall otherwise agree.

      7.   SECURITIES LAW LEGEND

           The Warrants and each certificate representing the Warrant Stock

      SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
      STATEMENT UNDER THE ACT OR AN EXEMPTION THEREFROM.

      8.   INDEMNIFICATION

           The Company agrees to indemnify and hold harmless the Agent and each
Purchaser from and against any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, attorneys' fees and
expenses (including reasonable attorneys' fees and disbursements and other costs
of investigations or defense, including those incurred upon any appeal) (each,
an "Indemnified Claim") which may be imposed upon, incurred by or asserted
against the Agent or such Purchaser in any manner relating to or arising out of
any untrue representation, breach of warranty or failure to perform any
covenants by the Company contained herein or in any certificate delivered
pursuant hereto; PROVIDED, that the Company shall not be liable for any
indemnification to the Agent or such Purchaser to the extent that any
Indemnified Claim was solely the result of its own gross negligence or willful
misconduct.

      9.   CONSIDERATION OF CERTAIN MATTERS

           The Company acknowledges that the Purchasers may from time to time
request the Agent or another representative designated by the Required

including, without limitation, coordinating any filings or notices that may be
required under federal securities laws.  If the Agent or such other

benefit of the parties to this Agreement and their respective successors and
permitted assigns.  Neither this Agreement nor any right, remedy, obligation or
liability arising hereunder or by reason hereof shall be assignable by the
Company, the Agent, or any Purchaser without the prior written consent of each
other party hereto, which consent shall not unreasonably be withheld;
PROVIDED, that any successor agent for Agent appointed under the Override

this Agreement or their respective successors or permitted assigns any legal or
equitable right, remedy or claim under or in respect of any agreement or any
provision contained herein.

           10.3  APPLICABILITY OF AGENCY PROVISIONS IN OVERRIDE AGREEMENT.
The Company, the Agent and each Purchaser acknowledge and agree that the
provisions of Article X of the Override Agreement apply generally to this
Agreement and any actions taken hereunder; PROVIDED, that solely with respect
to the application of those provisions to this Agreement and any actions taken

deemed a reference to "Purchaser" or "Purchasers", each reference to "Majority
Lenders" shall be deemed a reference to "Required Purchasers", and each
reference to "Pro Rata Share" shall be deemed a reference to "Warrant
Allocations".  If there is no longer an "Agent" acting under the Override
Agreement, any delivery or notice required to be made or given by the Company to
the Agent shall be delivered directly to each Purchaser then holding the
beneficial interest in any of the Securities.

           10.4  AMENDMENTS AND WAIVERS.  Any provision of this Agreement may
be amended or waived if, but only if, such


                                        8

<PAGE>

amendment or waiver is in writing and is signed by the Company, the Agent and
the Required Purchasers; PROVIDED, that (i) the consent of one hundred percent
(100%) of the Purchasers ("All Purchasers") shall be required to amend, modify
or waive any provision relating to (a) a change in the definitions of "Required
Purchasers", "All Purchasers" or "Warrant Allocations", or (b) any change that
subjects any Purchaser to any additional obligation, or (c) this SECTION
10.4; (ii) any change in the duties of or indemnities in favor of any
Purchaser or in a Purchaser's Warrant Allocations shall require the consent of
such Purchaser; and (iii) any change in the duties of or indemnities in favor of

           10.5  EFFECT OF WAIVERS; MODIFICATION OF DOCUMENTS.  The Agent's
or the Purchasers' failure, at any time or times, to require strict performance
by the Company or any other Person of any provision of this Agreement shall not
waive, affect or diminish any right of the Agent or the Purchasers to demand
strict compliance and performance therewith.  Any suspension or waiver by the
Agent or the Purchasers of any default under this Agreement shall not suspend,
waive or affect any other default under this Agreement, whether the same is
prior or subsequent thereto and whether of the same or of a different type.  No
waiver of any provision of this Agreement, nor consent to any departure by the
Company or any other Person therefrom shall in any event be effective unless the
same shall be in writing and signed by the Agent or the Required Purchasers or
All Purchasers, 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.

           10.6  SECTION AND OTHER HEADINGS.  The section and other headings
contained in this Agreement are for reference purposes only and shall not affect
the meaning or interpretation of this Agreement.

           10.7  SEVERABILITY.  In the event that any one or more of the
provisions contained in this Agreement shall be determined to be invalid,
illegal or unenforceable in any respect for any reason, the validity, legality
and enforceability of any such provision or provisions in every other respect
and the remaining provisions of this Agreement shall not be in any way impaired.

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

                                                                    Item 1.20A

Rights Agreement) the following respective meanings (such meanings being equally
applicable to both the singular and plural form of the terms defined):

representing at least an aggregate of fifty percent (50%) of the total of
Registrable Securities not previously sold in a public sale, requesting that the
Company effect the registration of Warrant Stock issuable upon the exercise of
such holder's Warrants or of any of such holder's Warrant Stock under the
Securities Act and specifying the intended method or methods of disposition
thereof, the Company shall promptly notify all holders of Warrants and Warrant
Stock in writing of the receipt of such request and each such holder, in lieu of
exercising its rights under SECTION 3, may elect (by written notice sent to
the Company within 10 Business Days from the date of such holder's receipt of
the aforementioned Company's notice) to have its shares of Warrant Stock
included in such registration thereof pursuant to this SECTION 2.  Thereupon
the Company shall, as expeditiously as is possible, use its best efforts to
effect the registration under the Securities Act of all shares of Warrant Stock
which the Company has been so requested to register by such holders for sale,
all to the extent


                                        2
<PAGE>



required to permit the disposition (in accordance with the intended method or
methods thereof, as aforesaid) of the Warrant Stock so registered; PROVIDED,
HOWEVER, that the Company shall not be required to effect more than two (2)
registrations of any Registrable Securities pursuant to this SECTION 2.

            3.    INCIDENTAL REGISTRATION.  If the Company at any time, on or
prior to July 31, 2003, proposes to file on its behalf and/or on behalf of any

(other than a Registration Statement on Form S-4 or S-8 or any successor form
for securities to be offered in a transaction of the type referred to in Rule
145 under the Securities Act or to employees of the Company pursuant to any
employee benefit plan, respectively) for the general registration of securities
with respect to its Common Stock or any other class of equity security (as
defined in Section 3(a)(11) of the Exchange Act) of the Company, it will give
written notice to all holders of Warrants or Warrant Stock at least 45 days
before the initial filing with the Commission of such Registration Statement,
which notice shall set forth the intended method of disposition of the
securities proposed to be registered by the Company.  The notice shall offer to
include in such filing the aggregate number of shares of Warrant Stock, and the
number of shares of Common Stock into which such Warrants are exercisable, as
such holders may request.  Nothing herein shall preclude the Company from
discontinuing the registration of its securities being effected on its behalf or
on behalf of the demanding security holders at any time prior to the effective
date of the Registration Statement relating thereto.

             Each holder of any such Registrable Securities desiring to have
Warrant Stock registered under this SECTION 3 shall advise the Company in
writing within 30 days after the date of receipt of such offer from the Company,
setting forth the number of shares of such Warrant Stock and shares of Common
Stock into which such Warrants are exercisable for which registration is
requested.  The Company shall thereupon include in such filing the number of
shares of Warrant Stock and shares of common stock into which such Warrants are
exercisable for which registration is so requested and shall use its best
efforts to effect registration under the Securities Act of such shares.  Except
as otherwise provided in SECTION 5, all expenses of such registration shall be
borne by the Company.

            4.    REGISTRATION PROCEDURES.  If the Company is required by the
provisions of SECTION 2 OR 3 to use its best efforts to effect the
registration of any of its securities under the Securities Act, the Company
will, as expeditiously as possible:



                                        3
<PAGE>



                  (a)   prepare and file with the Commission a Registration
Statement with respect to such securities and use its best efforts to cause such
Registration Statement to become and remain effective for a period of time
required for the disposition of such securities by the holders thereof;

                  (b)   prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such Registration Statement until
the earlier of such time as all of such securities have been disposed of in a
public offering or the expiration of 180 days;

                  (c)   furnish to any selling security holders such number of
copies of a summary prospectus or other prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such
other documents, as such selling security holders may reasonably request;

                  (d)   use its best efforts to register or qualify the
securities covered by such Registration Statement under such other securities or
blue sky laws of such jurisdictions within the United States and Puerto Rico as
each holder of such securities shall request (provided, however, the Company
shall not be obligated to qualify as a foreign corporation to do business under
the laws of any jurisdiction in which it is not then qualified or to file any
general consent to service of process), and do such other reasonable acts and
things as may be required of it to enable such holder to consummate the
disposition in such jurisdiction of the securities covered by such Registration
Statement;

                  (e)   unless waived in writing by each holder of securities
being included in such registration, use its best efforts to obtain from a
nationally recognized underwriter or investment banker a firm commitment
(pursuant to an underwriting agreement in customary form) to underwrite the
public offering of the securities covered by such Registration Statement;

                  (f)   furnish, at the request of any holder requesting
registration of Registrable Securities pursuant to SECTION 2, on the date that
such shares of Registrable Securities are delivered to the underwriters for sale
pursuant to such registration or, if such Registrable Securities are not being
sold through underwriters, on the date that the Registration Statement with
respect to such shares of Registrable Securities becomes effective, (1) a copy
of an opinion in form and substance satisfactory to such holder, dated such
date, of the independent counsel representing the Company for the purposes of
such


                                        4
<PAGE>



registration, addressed to the underwriters, if any, and to the holders making
such request, substantially to the effect that such Registration Statement has
become effective under the Securities Act and that (i) to the best knowledge of
such counsel, no stop order suspending the effectiveness thereof has been issued
and no proceedings for that purpose have been instituted or are pending or
contemplated under the Securities Act, (ii) the Registration Statement, the
related prospectus, and each amendment or supplement thereto, comply as to form
in all material respects with the requirements of the Securities Act and the
applicable rules and regulations of the Commission thereunder (except that such
counsel need express no opinion as to financial statements and data contained
therein), (iii) the descriptions in the Registration Statement or the
prospectus, or any amendment or supplement thereto, of all legal matters and
contracts and other legal documents or instruments are accurate and fairly
present the information required to be shown, and (iv) such counsel does not
know of any legal or governmental proceedings, pending or contemplated, required
to be described in the Registration Statement or prospectus, or any amendment or
supplement thereto, which are not described as required, nor of any contracts or
documents or instruments of a character required to be described in the
Registration Statement or prospectus, or any amendment or supplement thereto, or
to be filed as exhibits to the Registration Statement which are not described
and filed or incorporated by reference as required; such counsel shall also
confirm that it has no reason to believe that either the Registration Statement
or the prospectus, or any amendment or supplement thereto (other than financial
statements and data as to which such counsel need make no statement) contains
any untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which made, not misleading; and (2) a letter dated
such date, from the independent certified public accountants of the Company,
addressed to the underwriters, if any, and to the holders making such request
(or if such accountants are unable to deliver such letter to such holders under
applicable professional rules or guidelines, then to the Company) stating that
they are independent certified public accountants within the meaning of the
Securities Act and that, in the opinion of such accountants, the financial
statements and other financial data of the Company included in the Registration
Statement or the prospectus, or any amendment or supplement thereto, comply as
to form in all material respects with the applicable accounting requirements of
the Securities Act and, if permitted under applicable professional rules or
guidelines, that such opinion is rendered for the benefit of the selling
security holders and that they have a right to rely thereon.  Such opinion of
counsel shall additionally cover such other legal matters with respect to the
registration in respect of which such opinion is being given as such holders of
Registrable Securities may reasonably request.


                                        5
<PAGE>



Such letter from the independent certified public accountants shall additionally
cover such other financial matters (including information as to the period
ending not more than five Business Days prior to the date of such letter) with
respect to the registration in respect of which such letter is being given as
the holders of such securities may reasonably request;

                  (g)   enter into customary agreements (including an
underwriting agreement in customary form containing standard indemnification
provisions) and take such other actions as are reasonably required in order to
expedite or facilitate the disposition of such Registrable Securities; and
otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, but not later than 18 months after the effective
date of the Registration Statement, an earnings statement covering the period of
at least 12 months beginning with the first full month after the effective date
of such Registration Statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act.

            5.    EXPENSES; LIMITATIONS ON REGISTRATION.  All expenses
incurred in complying with this Agreement, including, without limitation, all
registration and filing fees (including all expenses incident to filing with the
NASD), printing expenses, fees and disbursements of counsel for the Company, the
reasonable fees and expenses of counsel for the selling security holders
(selected by those holding a majority of the shares being registered), expenses
of any special audits incident to or required by any such registration and
expenses of complying with the securities or blue sky laws of any jurisdictions
pursuant to SECTION 4(d), shall be paid by the Company, except that

                  (a)   all such expenses in connection with any amendment or
supplement to the Registration Statement or prospectus filed more than 180 days
after the effective date of such Registration Statement because any holder of
Registrable Securities has not effected the disposition of the securities
requested to be registered shall be paid by such holder; and

                  (b)   the Company shall not be liable for any fees, discounts
or commissions to any underwriter or any fees or disbursements of counsel for
any underwriter in respect of the securities sold by such holder of Registrable
Securities.

            It shall be a condition precedent to the obligation of the Company
to take any action pursuant to this Agreement in respect of the securities which
are to be registered at the request of any holder of Registrable Securities that
such holder shall furnish to the Company such information as may be deemed
necessary by the Company under the Securities Act with respect to such holder,
including information regarding the securities held


                                        6
<PAGE>



by such holder and the intended method of disposition thereof as the Company
shall reasonably request and as shall be required in connection with the action
taken by the Company.

            6.    INDEMNIFICATION AND CONTRIBUTION.

                  (a)   In the event of any registration of any Registrable
Securities under the Securities Act pursuant to this Agreement, the Company
shall indemnify and hold harmless the holder of such Registrable Securities,
such holder's directors and officers, and each other Person, if any, who
controls such holder within the meaning of the Securities Act, against any
losses, claims, damages or liabilities, joint or several, to which such holder
or any such director or officer or controlling Person may become subject under
the Securities Act or any other statute or at common law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any alleged untrue statement of any material fact
contained in any Registration Statement under which such securities were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereto, or (ii)
any alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and shall
reimburse such holder or such director, officer or controlling Person for any
legal or any other expenses reasonably incurred by such holder or such director,
officer or controlling Person in connection with investigating or defending any
such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any alleged untrue
statement or alleged omission made in such Registration Statement, preliminary
prospectus, prospectus or amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such holder
specifically for use therein.  Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such holder or
such director, officer or controlling Person, and shall survive the transfer of
such securities by such holder.

                  (b)   Each holder of Registrable Securities agrees to
indemnify and hold harmless the Company, its directors and officers and each
other Person, if any, who controls the Company within the meaning of the
Securities Act against any losses, claims, damages or liabilities, joint or
several, to which the Company or any such director or officer or any such Person
may become subject under the Securities Act or any other statute or at common
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon written information provided to
the Company by such holder of such Warrant or Warrant Stock specifically for use


                                        7
<PAGE>



therein and contained, on the effective date thereof, in any Registration
Statement under which securities were registered under the Securities Act at the
request of such holder, any final prospectus contained therein, or any amendment
or supplement thereto; PROVIDED, HOWEVER, that such holder's obligation
under this SECTION 6(b) to indemnify and hold harmless the Company shall in no
event exceed, with respect to all such obligations, the lesser of the proceeds
received by such selling security holder from the sale of the Registrable
Securities through such offering, or the damage attributable solely to the
inclusion of such written information in such Registration Statement,
prospectus, or amendment or supplement suffered by the Person or Persons whose
claims gave rise to such losses, claims, damages or liabilities; and FURTHER
PROVIDED, HOWEVER, that no such indemnity shall exist with respect to any
Person making claims or demands to whom the Company or any other Person
responsible for delivering a final Prospectus to such claimant failed to deliver
such prospectus as amended or supplemented.

                  (c)   If the indemnification provided for in this SECTION 6
from the indemnifying party is unavailable to an indemnified party hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
herein, then the indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and the indemnified parties in connection with the actions that resulted
in such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations.  The relative fault of such indemnifying
party and indemnified parties shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been made by, or relates to information supplied by, such indemnifying
party or indemnified parties, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such action.  The
amount paid or payable by a party as a result of the losses, claims, damages,
liabilities and expenses referred to above shall be deemed to include any legal
or other fees or expenses reasonably incurred by such party in connection with
any investigation or proceeding.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this SECTION 6(c) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall


                                        8
<PAGE>



be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

            7.    CERTAIN LIMITATIONS ON REGISTRATION RIGHTS.  Notwithstanding
the other provisions of this Agreement, the Company shall not be obligated to
register the Registrable Securities of any holder if (x) in the opinion of
counsel to the Company reasonably satisfactory to the holder and its counsel
(or, if the holder has engaged an investment banking firm, to such investment
banking firm and its counsel), the sale or other disposition of such stock, in
the manner proposed by such holder (or by such investment banking firm), may be
effected without registering such stock under the Securities Act, and (y) the
failure of the Company to register such stock will not result in a reduction in
the net proceeds to be received by such holder in connection with such sale or
other disposition.

            8.    MISCELLANEOUS.

                  (a)   NOTICES.  All notices, requests and other

hereafter specify for the purpose by notice to the Company.  Each such notice,
request or other communication shall be effective, (i) if given by facsimile

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 8(a).

                  (b)   SUCCESSORS AND ASSIGNS.  This Agreement shall inure to
the benefit of and be binding upon the successors and assigns of each of the
parties hereto including any Person to whom Registrable Securities are
transferred.

                  (c)   AMENDMENTS AND WAIVERS.  This Agreement may be
modified or amended or the provisions hereof waived with the written consent of
each of (i) the Company, (ii) the Majority Holders (as defined in the Antecedent
Debt Warrant) and (iii) the Majority Holders (as defined in the Metra Warrant).

headings contained in this Agreement are for reference purposes only and shall
not affect the meaning or interpretation of this Agreement.

number of counterparts, each of which shall be deemed to be an original and all
of which together shall be deemed to be one and the same instrument.

1995, between MORRISON KNUDSEN CORPORATION, a Delaware corporation (the

(the "Purchaser") and Purchaser as agent for certain cosureties and other
reinsurers (in such capacity, the "Agent"), is made with reference to the
following facts:


                                    RECITALS

          WHEREAS, the Company and Morrison Knudsen Corporation, an Ohio

described in EXHIBIT B hereto, after giving effect to the Closing and as of the

for the consideration set forth in SECTION 2.1, will constitute the legal, valid
and binding obligation of the Company, enforceable in accordance with its terms.
The issuance of the Warrant Stock has been duly authorized and, when issued upon
exercise of, and pursuant to, the Warrants, will have been validly issued and
will be fully paid and non-assessable, free and clear of all pledges, liens,
encumbrances and preemptive rights.  830,039 shares of Common Stock have been
duly reserved for issuance pursuant to the Warrants.

investment representations contained in SECTION 3.1, the offer, issuance, sale
and delivery of the Warrants as provided in this Agreement, and the offer,
issuance, sale and delivery of any Warrant Stock that may be issued to the
Purchaser upon exercise of, and pursuant to, the Warrants, are exempt from the
registration requirements of Section 5 of the Securities Act and all applicable
state securities laws.

          The Company covenants and agrees that from and after the date hereof,
except as otherwise provided herein, or unless the Purchaser has given its prior
written consent:

books of account with respect to its business activities in which proper
entries, reflecting all of its financial transactions, are made in accordance
with Generally Accepted Accounting Principles.  The Company shall permit the
Agent or its officers, employees, and/or agents, during normal business hours
(or at such other times as may reasonably be requested by the Agent), as
frequently as the Agent deems appropriate, to inspect such records and books of
account and the properties and facilities of the Company, and the Company shall
provide extracts and/or photocopies of such records and books of account as
reasonably requested by the Agent at no cost to the Agent.  The rights set forth
in this SECTION 5.1 shall not negate any other rights that the Agent may have
under any applicable law.

Company shall pay all expenses in connection with, and all taxes and other

of Common Stock issued upon such exercise hereof, acknowledge in writing, in
form reasonably satisfactory to such holder, its continuing obligation to afford
to such holder all such rights; PROVIDED, HOWEVER, that if such holder shall
fail to make any such request, such failure shall not affect the continuing
obligation of the Company to afford to such holder all such rights.


3.    TRANSFER, DIVISION AND COMBINATION

      3.1   TRANSFER.  Subject to compliance with SECTIONS 9 AND 14, transfer
of this Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the principal office of the Company referred to in
SECTION 2.1 or the office or agency designated by the Company pursuant to
SECTION 12, together with a written assignment of this Warrant substantially in
the form of EXHIBIT B hereto duly executed by Holder or its agent or attorney
and if such transfer is not to be made pursuant to SECTION 14, funds sufficient
to pay any transfer taxes payable upon the making of such transfer.  Upon such
surrender and, if required, such payment, the Company shall, subject to
SECTION 9, execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be canceled.  A
Warrant, if properly assigned in compliance with SECTION 9, may be exercised by
a new Holder for the purchase of shares of Common Stock without having a new
Warrant issued.  If requested by the Company, a new Holder shall acknowledge in
writing, in form reasonably satisfactory to the Company, such Holder's
continuing obligations under SECTIONS 9 AND 14 of this Warrant.

      3.2   DIVISION AND COMBINATION.  Subject to SECTION 9, this Warrant may
be divided or combined with other Warrants upon presentation hereof at the
aforesaid office or agency of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by Holder or its agent or attorney.  Subject to compliance with
SECTION 3.1 and with SECTION 9, as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

      3.3   EXPENSES.  The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
SECTION 3.

      3.4   MAINTENANCE OF BOOKS.  The Company agrees to maintain, at its
aforesaid office or agency, books for the registration, and the registration of
transfer, of the Warrants.


4.    ADJUSTMENTS

      The number of shares of Common Stock for which this Warrant is
exercisable, or the price at which such shares may be purchased upon exercise of
this Warrant, shall be subject to adjustment from time to time as set forth in
this SECTION 4.  The Company shall give each Holder notice of any event
described below which requires an adjustment pursuant to this SECTION 4 at the
time of such event.

      4.1   PREPAYMENT OF OBLIGATIONS UNDER OVERRIDE AGREEMENT.  The number of
shares of Common Stock for which this Warrant is exercisable immediately after
the occurrence of a Repayment Event shall be adjusted as follows:

- ------------------------------------------------------------------------------
If the Repayment Event occurs       Then the number of shares of Common Stock
during the following period         for which this Warrant is exercisable
                                    immediately prior to such event is reduced
                                    by
- ------------------------------------------------------------------------------
Closing Date through June 30,       100%
1996
- ------------------------------------------------------------------------------
July 1, 1996 through                50%
December 31, 1996
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

      4.2   STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any time the
Company shall:

            (a)  take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend

                                        9

<PAGE>

payable in, or other distribution of, Additional Shares of Common Stock;

            (b)  subdivide its outstanding shares of Common Stock into a larger
number of shares of Common Stock, or

            (c)  combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock,

then (i) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (ii) the Current Warrant Price
shall be adjusted to equal (A) the Current Warrant Price in effect immediately
prior to the occurrence of such event, multiplied by the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to the
adjustment divided by (B) the number of shares for which this Warrant is
exercisable immediately after such adjustment.

      4.3   OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION.  The
following provisions shall be applicable to the making of adjustments pursuant
to this SECTION 4, of the number of shares of Common Stock for which this
Warrant is exercisable:

            (a)  WHEN ADJUSTMENTS TO BE MADE.  The adjustments required by this
SECTION 4 shall be made whenever and as often as any specified event requiring
an adjustment shall occur, except that any adjustment of the number of shares of
Common Stock for which this Warrant is exercisable that would otherwise be
required may be postponed (except in the case of an adjustment pursuant to
SECTION 4.1 or a subdivision or combination of shares of the Common Stock, as
provided for in SECTION 4.2) up to, but not beyond the date of exercise of this
Warrant (or date of repurchase by the Company under SECTION 14) if such
adjustment either by itself or with other adjustments not previously made adds
or subtracts less than one percent (1%) of the shares of Common Stock for which
this Warrant is exercisable immediately prior to the making of such adjustment.
Any adjustment representing a change of less than such minimum amount (except as
aforesaid) which is postponed shall be carried forward and made as soon as such
adjustment, together with other adjustments required by this SECTION 4 and not
previously made, would result in a minimum adjustment or on the date of exercise
or repurchase.  For the purpose of any adjustment, any specified event shall be
deemed to have occurred at the close of business on the date of its occurrence.

                                       10

<PAGE>

            (b) FRACTIONAL INTERESTS.  In computing adjustments under this
SECTION 4, fractional interests in Common Stock shall be taken into account to
the nearest 1/10th of a share.

            (c)  WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver
such dividend or distribution, then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made
in respect thereof shall be rescinded and annulled.

      4.4   REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation), or sell,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then each Holder shall have the right thereafter to receive,
upon exercise of such Holder's Warrant, the number of shares of common stock of
the successor or acquiring corporation and Other Property receivable upon or as
a result of such reorganization, reclassification, merger, consolidation or
disposition of assets by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event.  In case of
any such reorganization, reclassification, merger, consolidation or disposition
of assets, the successor or acquiring corporation shall expressly assume the due
and punctual observance and performance of each and every covenant and condition
of this Warrant to be performed and observed by the Company and all the
obligations and liabilities hereunder, subject to such modifications as may be
deemed appropriate (as determined by resolution of the Board of Directors of the
Company) in order to provide for adjustments of the shares of Common Stock for
which this Warrant is exercisable, which adjustments shall be as nearly
equivalent as practicable to the adjustments provided for in this SECTION 4.
For purposes of this SECTION 4.4, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or rights on liquidation over any other class of stock
of such corporation and which is not subject to redemption and shall also
include any evidences of indebtedness, shares of stock or other securities which
are

                                       11
<PAGE>

convertible into or exchangeable for any such stock, either immediately or upon
a specified date or the happening of a specified event and any warrants or other
rights to subscribe for or purchase any such stock.  The foregoing provisions of
this SECTION 4.4 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or dispositions of assets.


5.    NOTICES TO WARRANT HOLDERS

      5.1   NOTICE OF ADJUSTMENTS.  Whenever the number of shares of Common
Stock for which this Warrant is exercisable, or whenever the price at which a
share of such Common Stock may be purchased upon exercise of the Warrants, shall
be adjusted pursuant to SECTION 4, the Company shall forthwith prepare a
certificate to be executed by the chief financial officer of the Company setting
forth, in reasonable detail, the event requiring the adjustment and the method
by which such adjustment was calculated, specifying the number of shares of
Common Stock for which this Warrant is exercisable and (if such adjustment was
made pursuant to SECTION 4.4) describing the number and kind of any other shares
of stock or Other Property for which this Warrant is exercisable, and any change
in the purchase price or prices thereof, after giving effect to such adjustment
or change.  The Company shall promptly cause a signed copy of such certificate
to be delivered to each Holder in accordance with SECTION 17.2.  The Company
shall keep at its office or agency designated pursuant to SECTION 12 copies of
all such certificates and cause the same to be available for inspection at said
office during normal business hours by any Holder or any prospective purchaser
of a Warrant designated by a Holder thereof.

      5.2   NOTICE OF CERTAIN CORPORATE ACTION.  The Holder shall be entitled
to the same rights to receive notice of corporate action as any holder of Common
Stock.

6.    NO IMPAIRMENT

      The Company shall not by any action avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms.  Without limiting the
generality of the foregoing, the Company will (a) not increase the par value of
any shares of Common Stock receivable upon the exercise of this Warrant above
the amount payable therefor upon such exercise immediately prior to such
increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock, upon the exercise of this Warrant, and
(c) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory

                                       12

<PAGE>

body having jurisdiction thereof as may be necessary to enable the Company to
perform its obligations under this Warrant.

      Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form reasonably
satisfactory to Holder, the continuing validity of this Warrant and the
obligations of the Company hereunder.


7.    RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR
      APPROVAL OF ANY GOVERNMENTAL AUTHORITY; PREFERRED STOCK

      From and after the Closing Date, the Company shall at all times reserve
and keep available for issuance upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants.  All shares of Common Stock
which shall be so issuable, when issued upon exercise of any Warrant and payment
therefor in accordance with the terms of such Warrant, shall be duly and validly
issued and fully paid and nonassessable, and not subject to preemptive rights.

      Before taking any action which would cause an adjustment reducing the
Current Warrant Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and nonassessable shares of such Common Stock at
such adjusted Current Warrant Price.

      Before taking any action which would result in an adjustment in the
number of shares of Common Stock for which this Warrant is exercisable or in the
Current Warrant Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

      If any shares of Common Stock required to be reserved for issuance upon
exercise of Warrants require registration or qualification with any governmental
authority under any federal or state law (otherwise than as provided in
SECTION 9) before such shares may be so issued, the Company will in good faith
and as expeditiously as possible and at its expense endeavor to cause such
shares to be duly registered or qualified.


8.    TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

      In the case of all dividends or other distributions by the Company to the
holders of its Common Stock with respect to which any provision of SECTION 4
refers to the taking of a record of such holders, the Company will in each such
case take such a

                                       13

<PAGE>

record and will take such record as of the close of business on a Business Day.
The Company will not at any time, except upon dissolution, liquidation or
winding up of the Company, close its stock transfer books or Warrant transfer
books so as to result in preventing or delaying the exercise or transfer of any
Warrant.


9.    RESTRICTIONS ON TRANSFERABILITY

      The Warrants and the Warrant Stock shall not be transferred, hypothecated
or assigned before satisfaction of the conditions specified in this SECTION 9,
which conditions are intended to ensure compliance with the provisions of the
Securities Act and state law, with respect to the Transfer of any Warrant or any
Warrant Stock.  Holder, by acceptance of this Warrant, agrees to be bound by the
provisions of this SECTION 9.

      9.1   RESTRICTIVE LEGEND.

            (a)  Except as otherwise provided in this SECTION 9, each
certificate for Warrant Stock initially issued upon the exercise of this
Warrant, and each certificate for Warrant Stock issued to any subsequent
transferee of any such certificate, shall be stamped or otherwise imprinted with
a legend in substantially the following form:

            "The shares represented by this certificate have not been
      registered under the Securities Act of 1933, as amended, and are
      subject to the conditions specified in a certain Warrant dated as
      of August ___, 1995, originally issued by Morrison Knudsen
      Corporation.  No transfer of the shares represented by this
      certificate shall be valid or effective until such conditions and
      any requirements of federal and state law have been fulfilled.  A
      copy of the form of said Warrant is on file with the Secretary of
      Morrison Knudsen Corporation.  The holder of this certificate, by
      acceptance of this certificate, agrees to be bound by the
      provisions of such Warrant."

            (b)  Except as otherwise provided in this SECTION 9, each Warrant
shall be stamped or otherwise imprinted with a legend in substantially the
following form:

            "This Warrant and the securities represented hereby have not been
      registered under the Securities Act of 1933, as amended, and may not be
      transferred in violation of such Act or state law, the rules and
      regulations thereunder or the provisions of this Warrant."

                                       14

<PAGE>

      9.2   NOTICE OF PROPOSED TRANSFERS; REQUESTS FOR REGISTRATION.  Prior to
any Transfer or attempted Transfer of any Warrants or any shares of Restricted
Common Stock, the holder of such Warrants or Restricted Common Stock shall give
10 days prior written notice (a "Transfer Notice") to the Company of such
holder's intention to effect such Transfer, describing the manner and
circumstances of the proposed Transfer, and shall deliver to the Company a
certificate of such holder representing and warranting that the proposed
Transfer of such Warrants or such Restricted Common Stock may be effected
without registration under the Securities Act.  After receipt of the Transfer
Notice and certificate, the Company shall, within five days thereof, so notify
the holder of such Warrants or such Restricted Common Stock and such holder
shall thereupon be entitled to Transfer such Warrants or such Restricted Common
Stock, in accordance with the terms of the Transfer Notice.  Each certificate,
if any, evidencing such shares of Restricted Common Stock issued upon such
Transfer shall bear the restrictive legend set forth in SECTION 9.1(a), and each
Warrant issued upon such Transfer shall bear the restrictive legend set forth in
SECTION 9.1(b).  The holder of the Warrants or the Restricted Common Stock, as
the case may be, giving the Transfer Notice shall not be entitled to transfer
and shall not transfer such Warrants or such Restricted Common Stock until
receipt of notice from the Company under this SECTION 9.2(a).

      The holders of Warrants and Warrant Stock shall have the right to request
registration of such Warrant Stock pursuant to and in accordance with the terms
of the Registration Rights Agreement.

      9.3   TERMINATION OF RESTRICTIONS.  Notwithstanding the foregoing
provisions of SECTION 9, the restrictions imposed by this SECTION 9 upon the
transferability of the Warrants, the Warrant Stock and the Restricted Common
Stock (or Common Stock issuable upon the exercise of the Warrants) and the
legend requirements of SECTION 9.1 shall terminate as to any particular Warrant
or share of Warrant Stock or Restricted Common Stock (or Common Stock issuable
upon the exercise of the Warrants) (i) when and so long as such security shall
have been effectively registered under the Securities Act and disposed of
pursuant thereto or (ii) when the Company shall have received an opinion of
counsel reasonably satisfactory to it that such legend is not required in order
to ensure compliance with the Securities Act.  Whenever the restrictions imposed
by this SECTION 9 shall terminate as to this Warrant, as hereinabove provided,
the Holder hereof shall be entitled to receive from the Company, at the expense
of the Company, a new Warrant bearing the following legend in place of the
restrictive legend set forth hereon:

            "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN WARRANT
      CONTAINED IN SECTION 9 HEREOF TERMINATED ON                , 19   , AND
      ARE OF NO FURTHER FORCE AND EFFECT."

                                       15

<PAGE>

All Warrants thereafter issued upon registration of transfer, division or
combination of, or in substitution for, any Warrant or Warrants entitled to bear
such legend shall have a similar legend endorsed thereon.  Whenever the
restrictions imposed by this SECTION 9 shall terminate as to any share of
Restricted Common Stock, as hereinabove provided, the holder thereof shall be
entitled to receive from the Company, at the Company's expense, a new
certificate representing such Common Stock not bearing the restrictive legend
set forth in SECTION 9.1(a).

      9.4   LISTING ON SECURITIES EXCHANGE.  So long as the Company shall list
any shares of Common Stock on any securities exchange, it will, at its expense,
list thereon, maintain and, when necessary, increase such listing of, all shares
of Common Stock issued or, to the extent permissible under the applicable
securities exchange rules, issuable upon the exercise of this Warrant, so long
as any shares of Common Stock shall be so listed during the Exercise Period.


10.   SUPPLYING INFORMATION

      The Company shall cooperate with each holder of a Warrant or Restricted
Common Stock in supplying such information as may be reasonably necessary for
such holder to complete and file any information reporting forms presently or
hereafter required by the Commission as a condition to the availability of an
exemption from the Securities Act for the sale of any Warrant or Restricted
Common Stock.


11.   LOSS OR MUTILATION

      Upon receipt by the Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity reasonably satisfactory to it, and in
case of mutilation upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder;
PROVIDED, in the case of mutilation, no indemnity shall be required if this
Warrant in identifiable form is surrendered to the Company for cancellation.


12.   OFFICE OF THE COMPANY

      As long as any of the Warrants remain outstanding, the Company shall
maintain an office or agency (which may be the principal executive offices of
the Company) where the Warrants may be presented for exercise, registration of
transfer, division or combination as provided in this Warrant.  The Company
shall notify Holder in writing prior to any change of the address of the office
at which the Warrants may be presented.

13.   FINANCIAL AND BUSINESS INFORMATION

      13.1  FILINGS.  So long as the Company is a "Public Company" (as
hereinafter defined), the Company will file with the Commission on or before the
due date all regular or periodic reports required to be filed pursuant to the
Exchange Act, and will deliver to the Holder, promptly upon its becoming
available, one copy of each report, notice or proxy statement sent by the
Company to its shareholders generally, and one copy of each regular or periodic

available) pursuant to the Securities Act, filed by the Company with (i) the
Commission or (ii) any securities exchange on which shares of the Common Stock
are listed.

            For purposes of this SECTION 13, the term "Public Company" shall
mean a company (i) that is subject to the reporting requirements of
Section 15(d) of the Exchange Act, or (ii) any of whose securities are
registered pursuant to Section 12(b) or 12(g) of the Exchange Act.

      13.2  QUARTERLY INFORMATION.  During any period in which the Company is
not a Public Company, as soon as available and in any event within 45 days after
the end of each of the first three fiscal quarters of each fiscal year of the
Company, the Company will deliver to the Agent a consolidated balance sheet of
the Company and its consolidated Subsidiaries as of the end of such quarter and
the related consolidated statements of income and cash flows for such quarter
and for the portion of the Company's fiscal year ended at the end of such
quarter, setting forth in the case of such income and cash flows in comparative
form the figures for the corresponding quarter and the corresponding portion of
the Company's previous fiscal year, all certified (subject to normal year-end
adjustments) as to fairness of presentation, GAAP, and consistency by the chief
financial officer, controller or treasurer of the Company.

consolidated balance sheet of the Company and its consolidated Subsidiaries as
of the end of such fiscal year and the related consolidated statements of
income, retained earnings and cash flows for such fiscal year, setting forth in
each case in comparative form the figures for the previous fiscal year, all
reported on in a manner acceptable to the Commission by Deloitte & Touche or
other independent public accountants of nationally recognized standing, together
with an unaudited annual report prepared on a consolidating basis in conformity
with GAAP.

14.   THE COMPANY'S REPURCHASE OF THE WARRANT

      14.1  OPTION TO REPURCHASE WARRANT.  From time to time on or after the
Initial Exercise Date and until the Expiration Date, the Company shall have the
right, upon not less than thirty (30) days prior written notice to any Holder,
to repurchase from such Holder, from any source of funds legally available
therefor, on the date and in the manner set forth in SECTION 14.2, all or any
part of the Warrant then held by such Holder for an amount  determined by
multiplying (x) the number of shares of Common Stock subject to such Warrant or
portion thereof being repurchased, by (y) the difference between (i) 110% of the
higher of the Current Market Price per share of Common Stock and the Current
Warrant Price per share of Common Stock as of the date of such notice, and
(ii) the Current Warrant Price per share of Common Stock as of the date of such
notice; PROVIDED, HOWEVER, that nothing herein shall preclude the exercise by
Holder of any portion of this Warrant exercisable at any time prior to such
repurchase.
      14.2  DETERMINATION AND PAYMENT OF REPURCHASE PRICE.

            (a)  The purchase price for any repurchase pursuant to this
SECTION 14 (the "Repurchase Price") shall be determined within ten (10) days of
the date of the repurchase notice given by the Company pursuant to SECTION 14.1,
and shall be payable in cash from any source of funds legally available therefor
within ten (10) days following the date of such determination of the Repurchase
Price.  On the date of any repurchase of this Warrant pursuant to this
SECTION 14, each Holder shall assign to the Company such Holder's Warrant or
portion thereof being repurchased, without any representations (other than a
representation that such Holder owns such Warrant free and clear of any liens,
pledges or encumbrances), by the surrender of such Holder's Warrant at the
principal office of the Company referred to in SECTION 2.1 against payment
therefor of the Repurchase Price by, at the option of such Holder, and subject
to the immediately following sentence, (i) wire transfer to an account in a bank
located in the United States designated by such Holder for such purpose or
(ii) a certified or official bank check drawn on a member of the New York
Clearing House payable to the order of such Holder.  If less than all of any
Holder's Warrant is being repurchased, the Company shall, pursuant to SECTION 3,
cancel such Warrant and issue in the name of, and deliver to, such Holder a new
Warrant for the portion not being repurchased.

            (b)  Each Holder of Warrants shall have the right at any time to
object to the determination of the Repurchase Price pursuant to this SECTION 14
by specifying in writing to the Company the nature of its objection and, unless
such objection is resolved by agreement of the Company and such Holder, the
Company and such Holder shall each have the right to subject the disputed
determination to separate firms of independent accountants of recognized
national standing for a joint resolution of the

                                       18

<PAGE>

objection of such Holder (which firms of independent accountants may, in either
case, be the firms of accountants regularly retained by the Company or such
Holder).  If such firms cannot jointly resolve the objection of such Holder,
then, unless otherwise directed by agreement of the Company and such Holder,
such firms shall in their sole discretion choose another firm of independent
certified public accountants of recognized national standing, which is not the
regular auditor of such Holder or the Company, which firm shall resolve such
objection.  In either case, for purposes hereof the determination so made shall
be conclusive and binding on the Company, such Holder and all Persons claiming
under or through any of them, and any adjustment in the determination of the
Repurchase Price per share of Common Stock resulting from such determination
shall be made.  The cost of any such determination shall be borne by the Company
if it results in an increase of the aggregate Repurchase Price for all shares of
Common Stock issuable upon the exercise hereof and by such Holder if it results
in no adjustment or a decrease of the aggregate Repurchase Price for all shares
of Common Stock issuable upon the exercise hereof.

            (c)  Any repurchase by the Company of all or any portion of the
Warrant pursuant to SECTION 14.1 which is delayed by (1) the failure of the
Company to determine the Repurchase Price within the time periods required in
SECTION 14.3(a) or (2) an objection by any Holder of the Warrant to any such
determination pursuant to SECTION 14.3(b) shall be consummated within ten (10)
days after, as the case may be, the determination of the Repurchase Price or the
resolution of such objection.

            (d)  In the event that the determination of the Repurchase Price
requires an opinion from an investment banking firm or accounting firm, all
costs and fees associated therewith shall, except to the extent otherwise
provided in SECTION 14.3(b) above, be paid by the Company.

      14.3  PRO RATA REPURCHASE OF WARRANTS.  Notwithstanding anything to the

such requirement.


15.   APPRAISAL

Majority Holders cannot agree on a mutually acceptable investment banking firm,
then the Majority Holders and the Company shall each choose one such investment
banking firm and the respective chosen firms shall agree on another investment
banking firm which shall make the determination.  The Company shall retain, at
its sole cost, such investment banking firms as may be necessary for the
determination of Appraised Value required by the terms of this Warrant.

      No provision hereof (including, without limitation, any of the provisions
under Section 7), in the absence of affirmative action by Holder to purchase
shares of Common Stock, and no enumeration herein of the rights or privileges of
Holder hereof, shall give rise to any liability of such Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such
liability is asserted by the Company, or by creditors of the Company.


17.   MISCELLANEOUS

      17.1  NONWAIVER AND EXPENSES.  No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies.
If the Company fails to make, when due, any payments provided for hereunder, or
fails to comply with any other provision of this Warrant, the Company shall pay
to Holder such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys' fees, including those of
appellate proceedings, incurred by Holder in collecting any amounts due pursuant
hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

costs, attorneys' fees, expenses or disbursements are found in a final non-
appealable judgment by a court to have resulted from either (i) Holder's gross
negligence or willful misconduct, (ii) actions or omissions taken or not taken

to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under
SECTIONS 9, 10, 13 AND 14 of this Warrant.  Each party agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by it of the provisions of SECTION 9, 10, 13 OR 14 of this Warrant and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate.

      17.5  SUCCESSORS AND ASSIGNS.  Subject to the provisions of SECTIONS 3.1
AND 9, this Warrant and the rights evidenced hereby shall inure to the benefit
of and be binding upon the successors of the Company and the successors and

amended or the provisions hereof waived with the written consent of the Company
and the Majority Holders; PROVIDED, HOWEVER, that no such Warrant may be
modified or amended to reduce the number of shares of Common Stock for which
such Warrant is exercisable (including, without limitation, by way of amendment
of SECTION 4.1), or to increase the price at which such shares may be purchased
upon exercise of such Warrant (before giving effect to any adjustment as
provided therein), or to modify the time period during which such Warrant may be
exercised without the prior written consent of the Holder thereof.

      17.7  SEVERABILITY.  Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such

          NOW, THEREFORE, in consideration of the premises and the covenants
hereinafter contained, it is agreed as follows:

          1.   DEFINITIONS.  Unless otherwise defined herein, terms defined in
the Warrant are used herein as therein defined, and the following shall have

laws of such jurisdictions within the United States and Puerto Rico as each
holder of such securities shall request (provided, however, the Company shall
not be obligated to qualify as a foreign corporation to do business under the
laws of any jurisdiction in which it is not then qualified or to file any
general consent to service of process), and do such other reasonable acts and
things as may be required of it to enable such holder to consummate the
disposition in such jurisdiction of the securities covered by such Registration
Statement;

               (e)  unless waived in writing by each holder of securities being
included in such registration, use its best efforts to obtain from a nationally

pending or contemplated under the Securities Act, (ii) the Registration
Statement, the related prospectus, and each amendment or supplement thereto,
comply as to form in all material respects with the requirements of the

Registration Statement or the prospectus, or any amendment or supplement
thereto, of all legal matters and contracts and other legal documents or
instruments are accurate and fairly present the information required to be

proceedings, pending or contemplated, required to be described in the

instruments of a character required to be described in the Registration
Statement or prospectus, or any amendment or supplement thereto, or to be filed
as exhibits to the Registration Statement which are not described and filed or
incorporated by reference as required; such counsel shall also confirm that it
has no reason to believe that either the Registration Statement or the
prospectus, or any amendment or supplement thereto (other than financial
statements and data as to which such counsel need make no statement) contains
any untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which made, not misleading; and (2) a letter dated

of the Company included in the Registration Statement or the prospectus, or any

the applicable accounting requirements of the Securities Act and, if permitted
under applicable professional rules or guidelines, that such opinion is rendered
for the benefit of the selling security holders and that they have a right to
rely thereon.  Such opinion of counsel shall additionally cover such other legal
matters with respect to the registration in respect of which such opinion is
being given as such holders of Registrable Securities may reasonably request.
Such letter from the independent certified public accountants shall additionally
cover such other financial matters (including information as to the period
ending not more than five Business Days prior to the date of such letter) with
respect to the registration in respect of which such letter is being given as

facilitate the disposition of such Registrable Securities; and otherwise use its

Commission, and make available to its security holders, as soon as reasonably
practicable, but not later than 18 months after the effective date of the
Registration Statement, an earnings statement covering the period of at least
12 months beginning with the first full month after the effective date of such
Registration Statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act.

controls such holder within the meaning of the Securities Act, against any
losses, claims, damages or liabilities, joint or several, to which such holder
or any such director or officer or controlling Person may become subject under
the Securities Act or any other statute or at common law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any alleged untrue statement of any material fact
contained in any Registration Statement under which such securities were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereto, or (ii)
any alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and shall
reimburse such holder or such director, officer or controlling Person for any
legal or any other expenses reasonably incurred by such holder or such director,
officer or controlling Person in connection with investigating or defending any
such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any alleged untrue
statement or alleged omission made in such Registration Statement, preliminary
prospectus, prospectus or amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such holder
specifically for use therein.  Such indemnity shall remain in full force and
effect regardless of any investigation

                                        6

<PAGE>

made by or on behalf of such holder or such director, officer or controlling
Person, and shall survive the transfer of such securities by such holder.

               (b)  Each holder of Registrable Securities agrees to indemnify
and hold harmless the Company, its directors and officers and each other Person,
if any, who controls the Company within the meaning of the Securities Act
against any losses, claims, damages or liabilities, joint or several, to which
the Company or any such director or officer or any such Person may become
subject under the Securities Act or any other statute or at common law, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon written information provided to the Company by
such holder of such Warrant or Warrant Stock specifically for use therein and
contained, on the effective date thereof, in any Registration Statement under
which securities were registered under the Securities Act at the request of such
holder, any final prospectus contained therein, or any amendment or supplement
thereto; PROVIDED, HOWEVER, that such holder's obligation under this
SECTION 6(b) to indemnify and hold harmless the Company shall in no event
exceed, with respect to all such obligations, the lesser of the proceeds
received by such selling security holder from the sale of the Registrable
Securities through such offering, or the damage attributable solely to the
inclusion of such written information in such Registration Statement,
prospectus, or amendment or supplement suffered by the Person or Persons whose
claims gave rise to such losses, claims, damages or liabilities; and FURTHER
PROVIDED, HOWEVER, that no such indemnity shall exist with respect to any Person
making claims or demands to whom the Company or any other Person responsible for
delivering a final Prospectus to such claimant failed to deliver such prospectus
as amended or supplemented.

               (c)  If the indemnification provided for in this SECTION 6 from
the indemnifying party is unavailable to an indemnified party hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
herein, then the indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and the indemnified parties in connection with the actions that resulted
in such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations.  The relative fault of such indemnifying
party and indemnified parties shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been made by, or relates to information supplied by, such indemnifying
party or indemnified

                                        7

<PAGE>

parties, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such action.  The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include any legal or other fees or expenses
reasonably incurred by such party in connection with any investigation or
proceeding.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this SECTION 6(c) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          7.   CERTAIN LIMITATIONS ON REGISTRATION RIGHTS.  Notwithstanding the
other provisions of this Agreement, the Company shall not be obligated to
register the Registrable Securities of any holder if (x) in the opinion of
counsel to the Company reasonably satisfactory to the holder and its counsel
(or, if the holder has engaged an investment banking firm, to such investment
banking firm and its counsel), the sale or other disposition of such stock, in
the manner proposed by such holder (or by such investment banking firm), may be
effected without registering such stock under the Securities Act, and (y) the
failure of the Company to register such stock will not result in a reduction in
the net proceeds to be received by such holder in connection with such sale or
other disposition.

          8.   MISCELLANEOUS.

               (a)  NOTICES.  All notices, requests and other communications to

      2.01 THE LOANS. Subject to and upon the terms and conditions set forth
herein, each Bank severally agrees, at any time and from time to time on and
after the Closing Date and prior to the Maturity Date, to make a loan or loans
(each a "LOAN" and collectively, the "LOANS") to the Company, which Loans
may be prepaid and reborrowed in accordance with the provisions hereof;
PROVIDED, HOWEVER, that (i) the aggregate principal amount of Loans
outstanding from any Bank shall at no time exceed the Commitment of such Bank
and (ii) the aggregate principal amount of Loans outstanding from all Banks
shall at no time exceed the then current Incremental L/C Reduction Amount.
Unless repaid in full prior thereto, all Loans shall be due and payable on the
Maturity Date.

       2.02 MINIMUM AMOUNT OF EACH BORROWING.  The aggregate principal amount
of each Borrowing shall not be less than $500,000.



                                        13
<PAGE>



      2.03  NOTICE OF BORROWING AND DISBURSEMENT REQUEST.

            (a)   Whenever the Company desires to make a Borrowing hereunder it
shall give the Agent at its Notice Office at least one Business Day's prior
irrevocable notice of each Loan to be made hereunder, PROVIDED THAT any such
notice shall be deemed to have been given on a certain day only if given before
11:00 a.m. (San Francisco time) on such day.  Each such notice (each, a "NOTICE
OF BORROWING")  (i) shall be irrevocable, (ii) shall be given by the Company in
the form of EXHIBIT B-1, appropriately completed to specify the date of such
Borrowing (which shall be a Business Day) and the aggregate principal amount of
the Loans to be made pursuant to such Borrowing (which amount, when added to the
aggregate principal amount of Loans then outstanding, shall not exceed the
Incremental L/C Reduction Amount as of the date of such Borrowing), and (iii)
shall be delivered no earlier than one calendar week after the previously
delivered Notice of Borrowing.  The Agent shall promptly give each Bank notice
of such proposed Borrowing, of such Bank's Commitment Percentage thereof and of
the other matters required by the immediately preceding sentence to be specified
in the Notice of Borrowing.

            (b)   Whenever the Company desires a disbursement of amounts from
the Loan Proceeds Account to the Operating Account hereunder it shall give the
Agent at its Notice Office irrevocable notice of each such disbursement to be
made hereunder, PROVIDED THAT any such notice shall be deemed to have been
given on a certain day only if given before 11:00 a.m. (San Francisco time) on
such day.  Each such notice (each, a "DISBURSEMENT REQUEST") (i) shall be
irrevocable, (ii) shall be given by the Company in the form of EXHIBIT B-2,
appropriately completed to specify the date of such disbursement (which shall be
a Business Day) and the aggregate principal amount of such disbursement, and
(iii) shall be delivered no more often than twice in any calendar week.  The
Agent shall promptly give each Bank notice of such disbursement or proposed
disbursement.

      2.04  DISBURSEMENT OF FUNDS.

            (a) No later than 11:00 a.m. (San Francisco time) on the date
specified in each Notice of Borrowing, each Bank will make available, through
such Bank's Lending Office, its Commitment Percentage of each Borrowing
requested to be made on such date, in Dollars and in immediately available funds
at the Agent's Payment Office and, upon receipt thereof, the Agent will deposit
the aggregate of the amounts made available by the Banks into the Loan Proceeds
Account.  Unless the Agent shall have been notified by any Bank prior to the
date of Borrowing that such Bank does not intend to make available to the Agent
such Bank's portion of any Borrowing to be made on such date, the Agent may
assume that such Bank has made such amount available to the Agent on such date
of Borrowing and the Agent may, in reliance upon such assumption, make available
to the Loan Proceeds Account a corresponding amount.  If such corresponding
amount is not in


                                        14
<PAGE>



fact made available to the Agent by such Bank, the Agent shall be entitled to
recover such corresponding amount from such Bank on demand.  If such Bank does
not pay such corresponding amount forthwith upon the Agent's demand therefor,
the Agent may either (i) withdraw any such corresponding amount from the Loan
Proceeds Account or (ii) notify the Company and the Company shall immediately
pay such corresponding amount to the Agent.  The Agent shall also be entitled to
recover on demand from such Bank or the Company interest on such corresponding
amount in respect of each day from the date such corresponding amount was made
available by the Agent to the Company until the date such corresponding amount
is recovered by the Agent, at a rate per annum equal to (a) if recovered from
such Bank, the Federal Funds Rate and (b) if recovered from the Company, the
Reference Rate for the first two Business Days after demand by the Agent and
thereafter at a rate per annum for overdue payments as provided in Section
2.08(c) hereof.  Nothing in this Section 2.04 shall be deemed to relieve any
Bank of its obligation to make Loans hereunder or to prejudice any rights which
the Company may have against any Bank as a result of any failure by such Bank to
make Loans hereunder.

            (b)   No later than 2:00 p.m. (San Francisco time) on the date
specified in each Disbursement Request and provided the applicable conditions to
a disbursement have been satisfied, the Agent will transfer the amounts
requested in the Disbursement Request from the Loan Proceeds Account to the
Operating Account.  The Agent shall have no duty to or liability to confirm the
information contained in any Disbursement Request and its sole duty thereunder
shall be to disburse the amounts specified in a Disbursement Request conforming
on its face to the requirements of Section 2.03(b) to the Operating Account.

      2.05  NOTES.

            (a)   The Company's obligation to pay the principal of, and interest
on, each of the Loans made by each Bank shall be evidenced by a promissory note
issued to such Bank (the "Note") duly executed and delivered by the Company
substantially in the form of Exhibit A hereto with blanks appropriately
completed in conformity herewith.

            (b)   The Note issued to each Bank shall (i) be payable to the order
of such Bank and be dated the Closing Date, (ii) be in a stated principal amount
equal to such Bank's Commitment and be payable in the principal amount of the
Loans evidenced thereby, (iii) mature, with respect to each Loan evidenced
thereby, on the Maturity Date, (iv) be subject to prepayments as provided in
Section 2.09, (v) bear interest as provided in Section 2.07 and (vi) be entitled
to the benefits of the Security Documents.

            (c)  Each Bank will note on its internal records the amount of each
Loan made by it and each payment in respect


                                        15
<PAGE>



thereof (which records shall, absent manifest error, be final and conclusive and
binding on all parties hereto) and will prior to any transfer of its Note
endorse on the reverse side thereof the outstanding principal amount of Loans
evidenced thereby.  Failure to make any such notation shall not affect the
Company's obligations in respect of such Loans.

      2.06  PRO RATA BORROWINGS.  All Borrowings of Loans under this Agreement
shall be made by the Banks pro rata on the basis of their Commitment Percentage.
It is understood that no Bank shall be responsible for any default by any other
Bank of its obligation to make Loans hereunder and that each Bank shall be
obligated to make the Loans provided to be made by it hereunder regardless of
the failure of any other Bank to make its Loans hereunder.

      2.07  COMPUTATION OF FEES AND INTEREST.

            (a)   All computations of fees (other than as provided in Section
2.15) and interest under this Agreement shall be made on the basis of a 360-day
year and actual days elapsed, which results in more interest being paid than if
computed on the basis of a 365-day year.  Interest and fees shall accrue during
each period during which interest or such fees are computed from the first day
thereof to the last day thereof.  Interest on each Loan shall be computed at and
accrue at the Reference Rate from and including the date on which each Loan is
made available to the Loan Proceeds Account.

            (b)   Each determination of an interest rate by the Agent pursuant
to any provision of this Agreement shall be conclusive and binding on the
Company and the Banks in the absence of manifest error.  The Agent will, at the
request of the Company or any Bank, deliver to the Company or the Bank, as the
case may be, a statement showing the quotations used by the Agent in determining
any interest rate.

            (c)  Accrued interest shall be payable (i) monthly in arrears on the
last Business Day of each calendar month, (ii) on the date of any repayment of
principal that reduces the outstanding principal amount of the Loans to zero,
(iii) at maturity (whether by acceleration or otherwise) of the Loans and (iv)
after such maturity, on demand.

      2.08  PAYMENTS BY THE COMPANY.

            (a)   All payments (including prepayments) to be made by the Company
on account of principal, interest, fees, and other sums due hereunder shall be
made without set-off or counterclaim and shall be made to the Agent, for the
account of the Banks, except as otherwise provided in this Agreement, at the
Agent's Payment Office, in Dollars and in immediately available funds no later
than 11:00 a.m. (San Francisco time) on the date when due.  In the case of
principal, interest, fees and other amounts which


                                        16
<PAGE>



are paid to the Agent for the account or benefit of all of the Banks the Agent
will promptly distribute to each Bank its Commitment Percentage of such
principal, interest, fees, or other amounts, in like funds as received.  Any
payment which is received by the Agent later than 11:00 a.m. (San Francisco
time) shall be deemed to have been received on the immediately succeeding
Business Day.

            (b)   Whenever any payment hereunder shall be stated to be due on a
day other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of interest or fees, as the case may be.

            (c)   In the event that any principal, interest (to the extent
permitted by law), fee, or any other amount due hereunder from the Company is
not paid on the date when due, such principal, interest, fee or other amount
shall thereafter bear interest at the Reference Rate plus 2%.

            (d) All payments (including prepayments), other than regularly
scheduled interest payments, on the Loans or on any of the other Obligations
shall be made to the Agent for application as follows (regardless of how the
Company may treat such payment for purposes of its own accounting): first, to
then due and outstanding fees, expenses or other charges of the Agent under this
Agreement or any of the other Related Documents to the extent payable by the
Company; second, to then due interest on the Loans accrued and unpaid prior to
the date such funds are received by the Banks and third, to the principal
balance of the Loans.

      2.09  PREPAYMENTS.

            (a)  The Company shall have the right to prepay the Loans in whole
or in part without penalty, premium or fee from time to time on the following
terms and conditions:  (i) the Company shall give the Agent at its Notice Office
at least one Business Day's prior notice of its intent to prepay the Loans and
the amount of such prepayment, which notice the Agent shall promptly transmit to
each of the Banks, PROVIDED THAT for the purposes of this clause (i) any
notice received after 11:00 a.m. (San Francisco time) shall not be deemed
delivered until the following Business Day; (ii) each partial prepayment of
Loans shall be in an aggregate principal amount of at least $1,000,000 and
$1,000,000 multiples in excess thereof and (iii) each prepayment in respect of
any Loans shall be applied as provided in Section 2.08.

            (b)  On any day on which amounts are deposited into the Metra
Payment Account, the Agent shall apply all such amounts in accordance with
Section 2.08(d); PROVIDED THAT (i) any amounts deposited into the Metra
Payment Account after 11:00 a.m. (San Francisco time) shall not be deemed
deposited until the following


                                        17
<PAGE>



Business Day; and (ii) each prepayment in respect of any Loans shall be applied
as provided in Section 2.08.

      2.10  SHARING OF PAYMENTS, ETC.  If, other than as expressly
contemplated herein, any Bank shall obtain on account of its Note or this
Agreement any payment (whether voluntary, involuntary, through the exercise of
any right of set-off, or otherwise) in excess of its Commitment Percentage of
payments on account of its Note or this Agreement obtained by all the Banks,
such Bank shall forthwith (a) notify the Agent of such fact, and (b) purchase
from the other Banks such participations in the Loans made by them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with
each of them; PROVIDED, HOWEVER, that if all or any portion of such excess
payment is thereafter recovered from the purchasing Bank, such purchase shall to
that extent be rescinded and each other Bank shall repay to the purchasing Bank
the purchase price paid thereto together with an amount equal to such paying
Bank's Commitment Percentage (according to the proportion of (i) the amount of
such paying Bank's required repayment to (ii) the total amount so recovered from
the purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  The Company agrees
that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.10 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off, but subject to Section 10.09)
with respect to such participation as fully as if such Bank were the direct
creditor of the Company in the amount of such participation.  Each Bank involved
in the purchase of a participation under this Section 2.10 or in a refund under
this Section 2.10 shall notify the Agent of the details of such purchase or
refund.  The Agent shall keep records (which shall be conclusive and binding in

purchases.

<PAGE>



present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of each Bank

Agent and any liability (including penalties, interest, additions to tax and

            (f)   Each Bank which is a foreign person (i.e., a person other than
a United States person for United States Federal income tax purposes) agrees
that:

             (i)  it shall, no later than the Closing Date (or, in the case of a
      Bank which becomes a party hereto pursuant to Section 10.08 after the
      Closing Date, the date upon which the Bank becomes a party hereto) deliver
      to the Agent (and the Agent shall deliver a copy thereof to the Company)
      two accurate and complete signed originals of Internal Revenue Service
      Form 4224 or any successor thereto ("FORM 4224"), or two accurate and
      complete signed originals of Internal Revenue Service Form 1001 or any
      successor thereto ("FORM 1001"), as appropriate, in each case indicating
      that the Bank is on the date of delivery thereof entitled to receive
      payment of principal, interest and fees under this Agreement free from
      withholding of United States Federal income tax;

            (ii)  if at any time such Bank makes any changes necessitating a new
      Form 4224 or Form 1001, it shall with reasonable promptness deliver to the
      Agent (and the Agent shall deliver a copy thereof to the Company) in
      replacement for, or in addition to, the forms previously delivered by it
      hereunder, two accurate and complete signed originals of Form 4224, or two
      accurate and complete signed originals of Form 1001, as appropriate, in
      each case indicating that such Bank is on the date of delivery thereof
      entitled to receive payment of reimbursements, interest, fees, and other
      sums under this Agreement free from withholding of United States Federal
      income tax;

           (iii)  it shall (to the extent it may lawfully do so), before or
      promptly after the occurrence of any event (including the passing of time
      but excluding any event mentioned in (ii) above) requiring a change or
      renewal in the most recent Form 4224 or Form 1001 previously delivered by
      such Bank, deliver to the Agent (and the Agent shall deliver a copy
      thereof to the Company) two accurate and complete original signed copies
      of Form 4224 or Form 1001 in replacement for the forms previously
      delivered by such Bank; and

            (iv)  it shall, promptly upon the Agent's or the Company's
      reasonable request to that effect, deliver to the Agent (and the Agent
      shall deliver a copy thereof to the Company) such other forms or similar
      documentation as may be required from time to time by any applicable law,
      treaty, rule or regulation in order to establish such Bank's tax status
      for withholding purposes.

            (g)   The Company will not be required to pay any additional amounts
in respect of United States Federal income tax pursuant to subsection 3.01(d)(i)
to any Bank for the account of any Lending Office of such Bank:


                                        21
<PAGE>



             (i)  if the obligation to pay such additional amounts would not
      have arisen but for a failure by such Bank to comply with its obligations
      under subsection 3.01(f) in respect of such Lending Office;

            (ii)  if such Bank shall have delivered to the Agent for delivery to
      the Company a Form 4224 in respect of such Lending Office pursuant to
      subsection 3.01(f), and such Bank shall not at any time be entitled to
      exemption from deduction or withholding of United States Federal income
      tax in respect of payments by the Company hereunder for the account of
      such Lending Office for any reason other than a change in United States
      law or regulations or in the official interpretation of such law or
      regulations by any Governmental Authority charged with the interpretation
      or administration thereof (whether or not having the force of law) after
      the date of delivery of such Form 4224; or

           (iii)  if the Bank shall have delivered to the Agent for delivery to
      the Company a Form 1001 in respect of such Lending Office pursuant to
      Section 3.01(f), and such Bank shall not at any time be entitled to
      exemption from deduction or withholding of United States Federal income
      tax in respect of payments by the Company hereunder for the account of
      such Lending Office for any reason other than a change in United States
      law or regulations or any applicable tax treaty or regulations or in the
      official interpretation of any such law, treaty or regulations by any
      Governmental Authority charged with the interpretation or administration
      thereof (whether or not having the force of law) after the date of
      delivery of such Form 1001.

            (h)   If, at any time, the Agent or the Company requests any Bank to
deliver any forms or other documentation pursuant to subsection 3.01(f)(iv),
then the Company shall, on demand of such Bank through the Agent, reimburse such
Bank for any costs and expenses (including expenses of outside legal counsel and
the allocated costs of in-house counsel) reasonably incurred by such Bank in the
preparation or delivery of such forms or other documentation.

            (i)   If the Company is required to pay additional amounts to any
Bank or the Agent pursuant to subsection 3.01(d), then such Bank shall use its
reasonable best efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Company which may thereafter accrue if such change in
the judgment of such Bank is not otherwise disadvantageous to such Bank.

municipal or other authority within the United States (including any agency or
subdivision thereof) asserts a claim that the Agent did not properly withhold
tax from amounts


                                        22
<PAGE>



paid to or for the account of a Bank (because the appropriate tax form was not
delivered, was not properly executed, because the Bank was not entitled to
exemption or reduction of withholding tax, or for any other reason), then that
Bank shall indemnify the Agent (to the extent the Agent has not been reimbursed
therefor by the Company) for all amounts paid directly or indirectly by the
Agent as tax or otherwise, including penalties and interest (and any taxes
imposed by any jurisdiction on the amounts payable tb the Agent hereunder),
together with all costs, expenses, and attorneys' fees (including the allocated
costs for in-house legal services).

      3.02  INCREASED COSTS AND REDUCTION OF RETURN.

            (a)   If any Bank shall determine that, due to either (i) the
introduction of or any change in the interpretation of any law or regulation or
(ii) the compliance with any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law), there shall be
any increase in the cost to such Bank of agreeing to issue, amend, maintain,
fund, or participate in this Agreement, any Loans, or its Commitment hereunder,
then the Company shall be liable for, and shall from time to time, upon demand
therefor by such Bank (with a copy of such demand to the Agent), pay to the
Agent for the account of such Bank, additional amounts as are sufficient to
compensate such Bank for such increased costs.

            (b)   If any Bank shall have determined that (i) the introduction
after the date hereof of any Capital Adequacy Regulation, (ii) any change in any
Capital Adequacy Regulation, (iii) any change in the interpretation or
administration of any Capital Adequacy Regulation by any central bank or other
Governmental Authority charged with the interpretation or administration
thereof, or (iv) compliance by such Bank (or its Lending Office) or any
corporation controlling such Bank, with any request, guideline or directive
regarding capital adequacy (whether or not having the force of law) of any such
central bank or other authority, affects or would affect the amount of capital
required or expected to be maintained by such Bank or any corporation
controlling such Bank and (taking into consideration such Bank's or such
corporation's policies with respect to capital adequacy and such Bank's desired
return on capital) determines that the amount of such capital is increased as a
consequence of its obligation under this Agreement, then such Bank shall
promptly notify the Company of such determination and, upon demand of such Bank
(and such Bank shall deliver a copy of such demand to the Agent), the Company
shall immediately pay to such Bank, from time to time as specified by such Bank,
additional amounts sufficient to compensate the Bank for such increase.

      3.03  CERTIFICATES OF BANKS.  Any Bank claiming reimbursement or
compensation pursuant to this Article III shall deliver to the Company (with a
copy to the Agent) a certificate


                                        23

such certificate shall be conclusive and binding on the Company in the absence
of manifest error.

in this Article III and of the Banks contained in Section 3.01(j) shall survive

perfected security interest in all such assets which are capable of being
perfected by the filing of a financing statement under applicable law, subject
only to Permitted Liens.

or levied against a substantial part of the Company's or any of its
Subsidiaries' assets and any such proceedings or petition shall not be
dismissed, or such writ, judgment, warrant of attachment, execution or similar
process shall not be released, vacated or fully bonded within 60 days after

respect to the Guarantor; or

            (i)    SECURITY DOCUMENTS.  The Guaranty, the Security Agreement,

obligation thereunder; or the Agent shall cease to have a first priority
mortgage on the Chicago, Cook County, Illinois leasehold property or a the first
priority, perfected security interest in the Collateral, subject only to
Permitted Liens.

      8.02  REMEDIES.  If any Event of Default occurs, the Agent shall, at the
request of, or may, with the consent of, the Majority Banks, (a) declare the
Commitments of each Bank to be terminated, whereupon such Commitments shall
forthwith be terminated; (b) declare the unpaid principal amount of all
outstanding Loans, all interest accrued and unpaid thereon and all other amounts
payable hereunder to be immediately due and payable, without presentment,
demand, protest or other notice of any kind, all of which are hereby expressly
waived by the Company; or (c) exercise all rights and remedies available to it
under this Agreement or the other Related Documents or applicable law;
PROVIDED, HOWEVER, that upon the occurrence of any event specified in clause
(e) or (f) of Section 8.01 above or upon the occurrence with respect to the
Guarantor of any event described in paragraphs (e) or (f) of Section 8.01 (in
the case of


                                        35
<PAGE>



such reference to clause (f) upon the expiration of the 60 day period mentioned
herein), the Commitment of each Bank shall automatically terminate and the
unpaid principal amount of all outstanding Loans and all interest and other
amounts as aforesaid shall automatically become due and payable without further
act of the Agent or any Bank.

      8.03  RIGHTS NOT EXCLUSIVE.  The rights provided for in this Agreement
and the other Related Documents are cumulative and are not exclusive of any
other rights, powers, privileges or remedies provided by law or in equity, or

                                  ARTICLE IX

                                  THE AGENT

      9.01  APPOINTMENT AND AUTHORIZATION.  Each Bank hereby irrevocably
appoints, designates and authorizes the Agent to enter into the Related
Documents to which it is a party and to take such action on its behalf under the
provisions of this Agreement and each other Related Document and to exercise
such powers and perform such duties as are expressly delegated to it by the
terms of this Agreement or any other Related Document, together with such powers
as are reasonably incidental thereto.  Notwithstanding any provision to the
contrary contained elsewhere in this Agreement or in any other Related Document,
the Agent shall not have any duties or responsibilities, except those expressly
set forth herein, or any fiduciary relationship with any Bank, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or any other Related Document or otherwise exist
against the Agent.  Without limiting the generality of the foregoing sentence,
the use of the term "agent" in this Agreement with reference to the Agent is not
intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine or any applicable law.  Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties.

      9.02  DELEGATION OF DUTIES.  The Agent may execute any of its duties
under this Agreement or any other Related Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties.  The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care.

      9.03  LIABILITY OF AGENT.  None of the Agent, its Affiliates, or any of
their respective officers, directors, employees, agents, or attorneys-in-fact
(collectively, the "AGENT-RELATED PERSONS") shall (i) be liable for any action
taken


                                        36
<PAGE>



or omitted to be taken by any of them under or in connection with this Agreement
or any Related Document or the transaction contemplated thereby (except for its
own gross negligence or willful misconduct) or (ii) be responsible in any manner
to any of the Banks for any recital, statement, representation or warranty made
by the Company or any Subsidiary or Affiliate of the Company or any officer
thereof contained in this Agreement or in any other Related Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Related Document, or the value of the Collateral or any other collateral,
or the validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any other Related Document, or for any failure of the Company
or any other party to any Related Document to perform its obligations hereunder
or thereunder.  No Agent-Related Person shall be under any obligation to any
Bank to ascertain or to inquire as to the observance or performance of any of
the agreements contained in, or conditions of, this Agreement or any other
Related Document, or to inspect the properties, books or records of the Company,
the Guarantor, or any of its Subsidiaries.

      9.04  RELIANCE BY AGENT.

            (a)   The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel (including counsel to the
Company), independent accountants and other experts selected by the Agent.  The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Related Document unless it shall first receive such
advice or concurrence of the Majority Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action.  The Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Agreement
or any other Related Document in accordance with a request or consent of the
Majority Banks and such request and any action taken or failure to act pursuant
thereto shall be binding upon all of the Banks.

            (b)   For purposes of determining compliance with the conditions
specified in Sections 4.01, each Bank which authorizes the Agent to release its
signature page to this Agreement shall be deemed to have consented to, approved
of, accepted or to be satisfied with, each of the conditions required to be
consented to, approved of, accepted by or satisfactory to, such Bank.



                                        37
<PAGE>



      9.05  NOTICE OF DEFAULT.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees payable
to the Agent for the account of the Banks, unless the Agent shall have received
written notice from a Bank or the Company referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default".  In the event that the Agent receives such a notice, the
Agent shall give notice thereof to the Banks.  The Agent shall take such action
with respect to such Default or Event of Default as shall be requested by the
Majority Banks in accordance with Article VIII; PROVIDED, HOWEVER, that
unless and until the Agent shall have received any such request, the Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or Event of Default as it shall deem
advisable or in the best interests of the Banks.

      9.06  CREDIT DECISION.  Each Bank expressly acknowledges that none of
the Agent-Related Persons has made any representation or warranty to it and that
no act by the Agent hereinafter taken, including any review of the affairs of
the Company, the Guarantor, and their Subsidiaries and Affiliates shall be
deemed to constitute any representation or warranty by the Agent to any Bank.
Each Bank represents to the Agent that it has, independently and without
reliance upon the Agent and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Company, the Guarantor, and their Subsidiaries and
Affiliates and all applicable bank regulatory laws relating to the transaction
contemplated hereby and made its own decision to enter into this Agreement and
extend credit to the Company hereunder.  Each Bank also represents that it will,
independently and without reliance upon the Agent and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Related Documents, and to make such
investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Company and the Guarantor.  Except for notices, reports
and other documents expressly required to be furnished to the Banks by the Agent
hereunder, the Agent shall not have any duty or responsibility to provide any
Bank with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of the
Company or the Guarantor which may come into the possession of any of the
Agent-Related Persons.

      9.07  INDEMNIFICATION OF AGENT.  The Banks shall indemnify upon demand
the Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Company and without limiting the obligation of the Company to do so), ratably
according to the


                                        38
<PAGE>



respective amounts of their Commitments, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses and disbursements of any kind whatsoever which may at any time
(including at any time following the repayment of the Obligations) be imposed
on, incurred by, or asserted against any such Person in any way relating to or
arising out of this Agreement or any Related Document or any document
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by any such Person
under or in connection with any of the foregoing; PROVIDED, HOWEVER, that no
Bank shall be liable for the payment to the Agent-Related Persons of any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from such
Person's gross negligence or willful misconduct.  Without limitation of the
foregoing, each Bank shall reimburse the Agent promptly upon demand for its
ratable share of any costs or out-of-pocket expenses (including fees and
expenses of counsel and the allocated cost of in-house counsel) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Related Document, or any
document contemplated by or referred to herein to the extent that the Agent is
not reimbursed for such expenses by or on behalf of the Company.  The
obligations of the Banks under this Section 9.07 shall survive the payment of
all Obligations hereunder.

      9.08  AGENT IN INDIVIDUAL CAPACITY.  BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from and
generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with the Company and its Subsidiaries and Affiliates as though
BofA were not the Agent hereunder and without notice to or consent of the Banks.
The Banks acknowledge that, pursuant to such activities, BofA or its Affiliates
may receive information regarding the Company or its Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Company or to such Affiliate) and acknowledge that the Agent shall be under no
obligation to provide such information to them.  With respect to its Loans and
Commitment, BofA shall have the same rights and powers under this Agreement as
any other Bank and may exercise the same as though it were not the Agent, and
the terms "Bank" and "Banks" shall include BofA in its individual capacity.

      9.09  SUCCESSOR AGENT.  The Agent may, and at the request of the
Majority Banks shall, resign as Agent upon 30 days' notice to the Banks.  If the
Agent shall resign as Agent under this Agreement, the Majority Banks, with the
consent of the Company (which consent shall not be unreasonably withheld), shall
appoint from among the Banks a successor agent for the Banks.  If no


                                        39
<PAGE>



successor agent is appointed prior to the effective date of the resignation of
the Agent, the Agent shall appoint, after consulting with the Banks and the
Company, a successor agent from among the Banks.  Upon the acceptance of its
appointment as successor agent hereunder, such successor agent shall succeed to
all the rights, powers and duties of the retiring Agent and the term "Agent"
shall mean such successor agent and the retiring Agent's rights, powers and
duties as Agent shall be terminated.  After any retiring Agent's resignation
hereunder as Agent, the provisions of this Article IX and Sections 10.04 and
10.05 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent under this Agreement.

      9.10  COLLATERAL MATTERS.

            (a)   The Agent is authorized on behalf of all the Banks, without
the necessity of any notice to or further consent from the Banks, from time to
time to take any action with respect to any collateral or the security
agreements and other documents relating to such collateral which may be
necessary to perfect and maintain perfected the security interest in and Liens
upon such collateral.

            (b)   The Banks irrevocably authorize the Agent, at its option and
in its discretion, to release any Lien granted to or held by the Agent upon any
collateral for the Obligations (i) upon termination of the Commitments and
payment in full of all the Obligations payable under this Agreement and under
any other Related Document; (ii) constituting assets sold or to be sold or
disposed of as part of or in connection with any disposition permitted
hereunder; (iii) constituting assets in which the Company or any Subsidiary of
the Company owned no interest at the time the Lien was granted or at any time
thereafter; (iv) constituting assets leased to the Company, the Guarantor, or
any Subsidiary of the Guarantor under a lease which has expired or been
terminated in a transaction permitted under this Agreement or is about to expire
and which has not been, and is not intended by the Company or such Subsidiary to
be, renewed or extended; (v) consisting of an instrument evidencing Indebtedness
or other debt instrument, if the indebtedness evidenced thereby has been paid in
full; or (vi) if approved, authorized or ratified in writing by the Majority
Banks as provided in subsection 10.01(f).  Upon request by the Agent at any
time, the Banks will confirm in writing the Agent's authority to release
particular types or items of collateral pursuant to this subsection 9.10(b).

                                MISCELLANEOUS

      10.01     AMENDMENTS AND WAIVERS.  No amendment or waiver of any
provision of this Agreement or any other Related Document and no consent with
respect to any departure by the Company


                                        40

therefrom, shall be effective unless the same shall be in writing and signed by
the Majority Banks, and then such waiver shall be effective only in the specific
instance and for the specific purpose for which given; PROVIDED, HOWEVER,
that no such waiver, amendment, or consent shall, unless in writing and signed
by all the Banks do any of the following:

            (a)   increase the Commitment of any Bank or subject any Bank to any
additional obligations;

            (b)   postpone or delay any date fixed for any payment of principal,
interest, fees or other amounts due hereunder or under any Related Document;

            (c)   reduce the principal of, or the rate of interest of any Loan,
or of any fees or other amounts payable hereunder or under any Related Document;

            (d)   change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Loans which shall be required for the Banks or
any of them to take any action hereunder;

            (e)   amend this Section 10.01 or Section 2.10;

the Guaranty or any amendment of Section 2 of the Guaranty; or

and, PROVIDED FURTHER, that no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Majority Banks, or all Banks
if so required by this Agreement, affect the rights or duties of the Agent under
this Agreement or any other Related Document.

      10.02  NOTICES.

            (a)   All notices, requests and other communications provided for

provides, telegraphic, telex, facsimile transmission or cable communication) and
mailed, telegraphed, telexed or delivered, (i) if to the Company, to its address
specified on Schedule I hereof, (ii) if to any Bank, to its Lending Office, and
(iii) if to the Agent, to its Notice Office; or, as to the Company, to such
other address as shall be designated by the Company in a written notice to the
other parties, and as to each other party, at such other address as shall be
designated by such party in a written notice to all other parties.  All notices,
requests, and other communications provided for hereunder shall, if sent by
facsimile, telegraphic, or telexed transmission, be confirmed in writing (other

Agent and the Banks in Article II herein to receive certain notices by telephone

The Agent and Banks shall be entitled to rely on the authority of any Person
purporting to be a Person authorized by the Company to give such notice and the
Agent and the Banks shall not have any liability to the Company or other Person
on account of any action taken or not taken by the Agent and the Banks in
reliance upon such telephonic or facsimile notice.  The obligation of the
Company to repay the Obligations shall not be affected in any way or to any
extent by any failure by the Agent and the Banks to receive written confirmation
of any telephonic or facsimile notice or the receipt by the Agent and the Banks
of a confirmation which is at variance with the terms understood by the Agent
and the Banks to be contained in the telephonic or facsimile notice.

      10.03  NO WAIVER; CUMULATIVE REMEDIES.  No failure to exercise and no
delay in exercising, on the part of any Agent or any Bank, any right, remedy,
power or privilege hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

      10.04  COSTS, EXPENSES AND CERTAIN FEES.  The Company shall, whether or
not the transactions contemplated hereby shall be consummated:

            (a)   pay or reimburse the Agent on demand for all costs and
expenses incurred in connection with the development, preparation, delivery,
administration and execution of, and any amendment, supplement, waiver or
modification to, this Agreement, any Related Document and any other documents
prepared in connection herewith or therewith, and the consummation of the
transactions contemplated hereby and thereby, including the reasonable costs and
expenses of counsel to the Agent (and the allocated cost of internal counsel)
with respect thereto;

            (b)   in the event the Agent takes any action in connection with the
enforcement or preservation of any rights (including in connection with any
Insolvency Proceeding,


                                        42
<PAGE>



"workout" or restructuring regarding the Company, this Agreement or any Related
Document), pay or reimburse the Agent on demand for all costs and expenses
incurred by them in connection with such enforcement or preservation of any
rights (including in connection with any Insolvency Proceeding, "workout" or
restructuring regarding the Company, this Agreement or any Related Document)
under this Agreement, any Related Document, and any such other documents,
including costs, fees and out-of-pocket expenses of counsel (and the allocated
cost of internal counsel) to the Agent; and

the Agent and each of their respective officers, directors, employees, counsel,
agents and attorneys-in-fact (each, an "INDEMNIFIED PERSON") harmless from and

actions, judgments, suits, costs, charges, expenses or disbursements (including
fees and expenses of counsel and allocated costs of internal counsel) of any
kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration (including any action taken or not taken by an
Indemnified Person pursuant to Section 10.02 hereof) of this Agreement and any
other Related Documents or the transactions contemplated herein, and with
respect to any investigation, litigation or proceeding related to this Agreement
or any Related Document or the use hereof or thereof (whether or not any
Indemnified Person is a party thereto) (all the foregoing, collectively, the
"INDEMNIFIED LIABILITIES"); PROVIDED, that the Company shall have no
obligation hereunder to any Indemnified Person with respect to Indemnified
Liabilities arising from the gross negligence or willful misconduct of such
Indemnified Person.  The agreements in this section shall survive payment of all
other Obligations.

      10.06  MARSHALLING; PAYMENTS SET ASIDE.  Neither the Agent nor the Banks
shall be under any obligation to marshall any assets in favor of the Company or
any other Person or against or in payment of any or all of the Obligations.  To
the extent that the Company makes a payment or payments to the Agent or the
Banks, or the Agent or the Banks enforce their Liens or exercise their rights of
set-off, and such payment or payments or the proceeds of such enforcement or
set-off or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party in connection with any Insolvency


                                        43
<PAGE>

part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such
enforcement or set-off had not occurred.

      10.07  SUCCESSORS AND ASSIGNS.  The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Company may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of each Bank.

      10.08  ASSIGNMENTS, PARTICIPATIONS, ETC.

            (a)   Prior to the Maturity Date, the Commitments, Loan and
obligations of any Bank may not be assigned.  From and after the Maturity Date,
any Bank may, with the written consent of the Agent, at any time assign and
delegate to one or more Eligible Assignees (provided that no written consent of
the Agent shall be required in connection with any assignment and delegation by
a Bank to a Bank Affiliate of such Bank) (each an "ASSIGNEE") all or any
ratable part of all of the Commitments, Loans and the other rights and
obligations of such Bank hereunder, in a minimum amount of $1,000,000;
PROVIDED, HOWEVER, that (i) the Company and may continue to deal solely and
directly with such Bank in connection with the interest so assigned to an
Assignee until (A) written notice of such assignment, together with payment
instructions, addresses and related information with respect to the Assignee
shall have been given to the Company and the Agent by such Bank and the
Assignee; and (B) such Bank and its Assignee shall have delivered to the Company
and the Agent an Assignment and Acceptance in the form of EXHIBIT F (an
"ASSIGNMENT AND ACCEPTANCE") and (ii) until such time as the Reimbursement
Agreement shall have been terminated, no such assignment shall be effective
unless concurrently with the delivery of such assignment, such Bank shall have
assigned the same proportion of its Commitment and L\C Borrowings (each as
defined in the Reimbursement Agreement) and other rights and obligations under
the Reimbursement Agreement to such Assignee pursuant to the terms of the
Reimbursement Agreement.

            (b)   From and after the date that the Agent notifies the assignor
Bank that it has received an executed Assignment and Acceptance, payment of the
processing fee and when applicable, the applicable assignment and acceptance to
be delivered under the Reimbursement Agreement, (i) the Assignee thereunder
shall be a party hereto and, to the extent that rights and obligations hereunder
have been assigned to it pursuant to such Assignment and Acceptance, shall have
the rights and obligations of a Bank under the Related Documents, and (ii) the
assignor Bank shall, to the extent that rights and obligations hereunder have
been assigned by it pursuant to such Assignment and Acceptance,


                                        44
<PAGE>



relinquish its rights and be released from its obligations under the Related
Documents.

            (c)   Immediately upon each Assignee making its payment under the
Assignment and Acceptance, this Agreement shall be deemed to be amended to the
extent, but only to the extent, necessary to reflect the addition of the
Assignee and the resulting adjustment of the Commitments arising therefrom.  The
Commitment allocated to each Assignee shall reduce such Commitment of the
assigning Bank pro tanto.

            (d)   Any Bank may at any time sell to one or more commercial banks
(a "PARTICIPANT") participating interests in the Commitment and Loans of that
Bank and the other interests of that Bank (the "ORIGINATING BANK") hereunder
and under the other Related Documents; PROVIDED, HOWEVER, that (i) the
Originating Bank's obligations under this Agreement shall remain unchanged, (ii)
the Originating Bank shall remain solely responsible for the performance of such
obligations, (iii) the Company and the Agent shall continue to deal solely and
directly with the Originating Bank in connection with the Originating Bank's
rights and obligations under this Agreement and the other Related Documents, and
(iv) no Bank shall transfer or grant any participating interest under which the
Participant shall have rights to approve any amendment to, or any consent or
waiver with respect to, this Agreement or any other Related Document, except to
the extent such amendment, consent or waiver would require unanimous consent as
described in the first PROVISO to Section 10.01.  In the case of any such
participation, the Participant shall not have any rights under this Agreement,
or any of the other Related Documents, and all amounts payable by the Company
hereunder shall be determined as if such Bank had not sold such participation;
except that, if amounts outstanding under this Agreement are due and unpaid, or
shall have been declared or shall have become due and payable upon the
occurrence of an Event of Default, each Participant shall be deemed to have the
right of set-off in respect of its participating interest in amounts owing under
this Agreement to the same extent as if the amount of its participating interest
were owing directly to it as a Bank under this Agreement.

            (e)   Each Bank agrees to take normal and reasonable precautions and
exercise due care to maintain the confidentiality of all non-public information
provided to it by the Company or any Subsidiary of the Company, or by the Agent
on such Company's or Subsidiary's behalf, in connection with this Agreement or
any other Related Document, and neither it nor any of its Affiliates shall use
any such information for any purpose or in any manner other than pursuant to the
terms contemplated by this Agreement; except to the extent such information (i)
was or becomes generally available to the public other than as a result of a
disclosure by the Bank, or (ii) was or becomes available on a non-confidential
basis from a source other than the Company, provided that such source is not
bound by a confidentiality


                                        45
<PAGE>



agreement with the Company known to the Bank; PROVIDED FURTHER, HOWEVER,
that any Bank may disclose such information, (a) at the request or pursuant to
any requirement of any Governmental Authority to which the Bank is subject or in
connection with an examination of such Bank by any such authority; (b) pursuant
to subpoena or other court process; (c) when required to do so in accordance
with the provisions of any applicable Requirement of Law; (d) to such Bank's
independent auditors and other professional advisors; and (e) to any other
financial institution who has advanced funds to or made other financial
accommodations on behalf of the Company.  Notwithstanding the foregoing, the
Company authorizes each Bank to disclose to any Participant or Assignee (each, a
"TRANSFEREE") and to any prospective Transferee, such financial and other
information in such Bank's possession concerning the Guarantor or its
Subsidiaries which has been delivered to the Agent or the Banks pursuant to this
Agreement or which has been delivered to the Agent or the Banks by the Company
in connection with the Banks' credit evaluation of the Company; PROVIDED that,
unless otherwise agreed by the Company, such Transferee agrees in writing to
such Bank to keep such information confidential to the same extent required of
the Banks hereunder.

      10.09  SET-OFF.  (a) In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists, each Bank is authorized at any
time and from time to time, without prior notice to the Company, any such notice
being waived by the Company to the fullest extent permitted by law, to set-off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time owing by such Bank
to or for the credit or the account of the Company against any and all
obligations of the Company now or hereafter existing under this Agreement or any
other Related Document irrespective of whether or not the Agent or such Bank
shall have made demand under this Agreement or any Related Document and although
such obligations may be contingent or unmatured.  Each Bank agrees promptly to
notify the Company and the Agent after any such set-off and application made by
such Bank; PROVIDED, HOWEVER, that the failure to give such notice shall not
affect the validity of such set-off and application.  The rights of each Bank
under this Section 10.09 are in addition to the other rights and remedies
(including without limitation, other rights of set-off) which the Bank may have.
Notwithstanding anything else to the contrary herein or in any Related Document,
the Agent expressly agrees that it will not exercise set-off rights in respect
of this Agreement or any Related Document other than in respect of the
Collateral.

            (b)  Notwithstanding the foregoing subsection (a), at any time that
the Loans or any other Obligation shall be secured by real property located in
California, no Bank shall exercise a right of setoff, banker's lien or
counterclaim or take any court or administrative action or institute any
proceeding to enforce any provision of this agreement or any Note that is not
taken by


                                        46
<PAGE>



the Majority Banks or approved in writing by the Majority Banks if such setoff
or action or proceeding would or might (pursuant to Sections 580a, 580b, 580d
and 726 of the California Code of Civil Procedure or Section 2924 of the
California Civil Code, if applicable, or otherwise) affect or impair the
validity, priority, or enforceability of the liens granted to the Agent pursuant
to the Security Documents or the enforceability of the Notes and other
Obligations hereunder, and any attempted exercise by any Bank of any such right
without obtaining such consent of the Majority Banks shall be null and void.
This subsection (b) shall be solely for the benefit of each of the Banks
hereunder.

      10.10  NOTIFICATION OF ADDRESSES, LENDING OFFICES, ETC.  Each Bank shall
notify the Agent in writing of any changes in the address to which notices to
the Bank should be directed, of addresses of its Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

      10.11  COUNTERPARTS.  This Agreement may be executed by one or more of
the parties to this Agreement in any number of separate counterparts, each of
which, when so executed, shall be deemed an original, and all of said
counterparts taken together shall be deemed to constitute but one and the same
instrument.  A set of the copies of this Agreement signed by all the parties
shall be lodged with the Company and the Agent.

      10.12  SEVERABILITY.  The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality of, enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

      10.13  TIME.  Time is of the essence as to each term or provision of
this Agreement and each of the other Related Documents.

      10.14  GOVERNING LAW AND JURISDICTION.

            (a)   THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA.

            (b)   ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT
MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES

AGREEMENT, EACH OF THE COMPANY, THE AGENT AND THE BANKS CONSENTS, FOR ITSELF AND

PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT


                                        47
<PAGE>



RELATED HERETO.  THE COMPANY, THE AGENT AND THE BANKS EACH WAIVE PERSONAL
SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY
OTHER MEANS PERMITTED BY CALIFORNIA LAW.

OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER
PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR
OTHERWISE.  THE COMPANY, THE BANKS AND THE AGENT AGREE THAT ANY SUCH CLAIM OR
CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY.  WITHOUT
LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO
A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION,
COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE

between and has been reviewed by counsel to the Agent, the Banks, the Company

                              GUARANTY


            This GUARANTY is entered into as of July 31, 1995, between MORRISON

            B.    Pursuant to the Reimbursement Agreement, the issuing bank
issued a letter of credit on behalf of the Borrower.

            C.    Pursuant to a Guaranty dated as of August 4, 1992 (as amended,

and obligations under the Credit Agreement.

            NOW, THEREFORE, in consideration of the premises and the mutual

provision of the UCC requiring that the Collateral be disposed of in a
commercially reasonable manner, which Borrower, Guarantor, 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,
guaranty, or any debt instrument evidencing the Obligations or the Guaranty
Liabilities;

            (h)   Agent's or any Bank's vote, claim, distribution, election,
acceptance, action, or inaction in


                                     -4-
<PAGE>


any bankruptcy or reorganization case related to the Collateral, the
Obligations, or the Guaranty Liabilities;

            (i)   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

            (j)   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 Guarantor 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 payable, then Guarantor
shall, upon demand in writing therefor by Agent to Guarantor, 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 5.  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, Guarantor waives and agrees as follows:

            (a)    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


                                     -5-
<PAGE>


Liabilities, or to pursue any other right or remedy in Agent's or any Bank's
power that Guarantor may or may not be able to pursue itself and that may
lighten Guarantor's burden, before proceeding against the Collateral.  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.  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.

            (b)   Guarantor has entered into this Guaranty based solely upon its
independent knowledge of Borrower's financial condition and Guarantor assumes
full responsibility for obtaining any further information with respect to
Borrower or the conduct of its business.  Guarantor represents that it is now,
and during the terms of this Guaranty will be, responsible for ascertaining the
financial condition of Borrower.  Guarantor hereby waives any duty on the part
of Agent or any Bank to disclose to 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.  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 Guarantor or in payment of any or all of the
Obligations or Guaranty Liabilities.

            (d)  Guarantor hereby waives:  (i) presentment, demand, protest,
notice of acceleration, dishonor, non-payment, protest, or any delay related
thereto, with


                                     -6-
<PAGE>


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 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
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, 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 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 6.  The amount of the successful bid at any such sale, whether Agent or
any other party (including Guarantor) 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 6 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


                                     -7-
<PAGE>


deficiency claim to which Agent might otherwise be entitled but for such bidding
at any such sale.

            (e)  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 Guarantor, for business and commercial purposes only.  Guarantor
agrees that any claim of Agent or any Bank against Guarantor arising out of this
Guaranty arises out of the conduct by Guarantor of its trade, business, or
profession.  Guarantor undertakes all the risks encompassed in the 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
Guarantor, may release, add, subordinate or substitute security for the
Obligations or the Guaranty Liabilities.

            (f)  Guarantor waives and agrees that it shall not at any time
insist upon, plead, or in any manner 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 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 Guarantor 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, 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 Guarantor's liability to pay and perform the Guaranty Liabilities.

      2.5   WAIVERS UNDER STATUTES.  Guarantor expressly acknowledges that:

            (a)   If Borrower defaults in the payment or performance of the
Obligations and Guarantor pays to Agent all or part of the Obligations,
Guarantor would have a right to proceed against Borrower to the extent of the
Obligations so paid by Guarantor and to have the benefit of


                                     -8-
<PAGE>


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 Guarantor.  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, Guarantor's 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, Guarantor might have a defense
against payment under this Guaranty.

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

            Nevertheless, Guarantor expressly, knowingly and intentionally
waives and relinquishes any and all rights, defenses or benefits Guarantor might
have under CCP Sections 580a or 580d or similar laws.  In addition, Guarantor
also expressly, knowingly and intentionally waives and relinquishes any and all
rights, defenses or benefits Guarantor may have based upon an election of
remedies by Agent which in any manner impairs, affects, reduces, releases,
destroys and/or extinguishes Guarantor's subrogation rights and/or 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, Guarantor agrees that
this Guaranty will remain fully effective and 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 Guarantor from taking any
action against Borrower to recover any amounts paid by Guarantor to Agent under
this


                                     -9-
<PAGE>


Guaranty or otherwise limits or destroys Guarantor's right of subrogation.

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

      2.6  WAIVERS OF DEFENSES.   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
purposes represented to, or intended or understood by, Agent, Banks or
Guarantor; (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.

            Without limiting the generality of the foregoing, 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 Guarantor, and Guarantor may not assign, transfer, or endorse
this Guaranty.  In the event all or


                                     -10-
<PAGE>


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.  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 Credit Agreement,
regardless of whether the Obligations may, in successive transactions, be paid,
repaid, advanced, or renewed from time to time.

      2.9   SUBORDINATION.

            (a)   Guarantor hereby agrees that all obligations and all
indebtedness of Borrower to 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 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, 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 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)   Guarantor shall not 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.  Guarantor shall not demand payment of, accelerate
the maturity of, or declare a


                                     -11-
<PAGE>


default or event of default under the Subordinated Indebtedness unless and until
the Obligations are paid in full.  Guarantor shall not cause or permit Borrower
to make or give, and Guarantor shall not receive or accept, payment in any form
(direct or indirect, including by transfer to an affiliate or subsidiary of
Borrower or 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, transfer, or collateral security so
made or given by Borrower and received or accepted by Guarantor, without the
express prior written consent of the Majority Banks, shall be held in trust by
Guarantor for Agent, for the account of Agent and Banks, and 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.

            Guarantor will not 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 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 Credit
Agreement.  If (i) 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 Guarantor's request, execute and deliver to Guarantor appropriate documents,
without recourse and without representation or warranty, necessary to evidence
the transfer by subrogation to Guarantor of an interest in the Obligations
resulting from such payment by Guarantor.

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


                                     -12-
<PAGE>


      2.12  NO OFFSET, DEFENSE, OR COUNTERCLAIM.  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 Guarantor specifically waives its right to assert any
such defense or right of offset.  Guarantor further agrees that the Guaranty
Liabilities shall not be subject to any counterclaims, 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, Guarantor, or other guarantor
of the Obligations may have or assert.

      2.13  CONSULTATION WITH LEGAL COUNSEL.       Guarantor acknowledges that
the waivers in Section 2.4, 2.5 and 2.6 herein are a material inducement to
Banks to make the Loans under the Credit Agreement and that Banks are relying
upon the foregoing waivers in its future dealings with Borrower.  Guarantor
acknowledges and certifies that it has reviewed the foregoing waivers with its
legal counsel and that, after such review with its legal counsel, Guarantor has
agreed to the foregoing waivers.

3.    PAYMENTS FREE AND CLEAR OF TAXES

      All payments required to be made by Guarantor hereunder shall be made to
Agent free and clear of, and without deduction for, any and all present or
future Taxes or Other Taxes that would otherwise have been payable by Agent for
the account of each Bank if Borrower had paid the Obligations under the Credit
Agreement to Agent in accordance with the terms of the Related Documents.  Upon
request by Agent, Guarantor shall furnish to Agent a receipt for any Taxes or
Other Taxes paid by Guarantor pursuant to this Section 3 or, if no Taxes or
Other Taxes are payable with respect to any payments required to be made by
Guarantor hereunder, either a certificate from each appropriate taxing authority
or an opinion of counsel acceptable to Agent, in either case stating that such
payment is exempt from or not subject to Taxes or Other Taxes.  If Taxes or
Other Taxes are paid by Agent on behalf of any Bank, as a result of payments
under this Guaranty, Guarantor will, upon demand of Agent, and whether or not
such Taxes or Other Taxes shall be correctly or legally asserted, indemnify
Agent and Banks for such payments, together with any interest, penalties, and
expenses in connection therewith plus interest thereon at the rate


                                     -13-
<PAGE>


applicable to overdue amounts under the Credit Agreement.  Guarantor will assume
all the rights and responsibilities of Borrower as set forth in Section 3.01 of
the Credit Agreement, and Agent and Banks will assume all of the rights and
responsibilities of Agent and Banks as set forth in Section 3.01(f) of the
Credit Agreement.

4.    REINSTATEMENT

      This Guaranty shall remain in full force and effect and continue to be
effective, as the case may be, if at any time payment and performance of the
Obligations under the Credit Agreement or the Guaranty Liabilities, or any part
thereof, is, pursuant to applicable law, avoided, rescinded or reduced in
amount, or must otherwise be restored or returned by Agent or any Bank or any
obligee of the Obligations under the Credit Agreement or the Guaranty
Liabilities, whether as a "voidable preference," "fraudulent conveyance," or
otherwise, all as though such payment or performance had not been made.  In the
event that any payment, or any part thereof, is avoided, rescinded, reduced,
restored, or returned, the Obligations under the Credit Agreement or the
Guaranty Liabilities, as the case may be, shall be reinstated and deemed reduced
only by such amount paid and not so avoided, rescinded, reduced, restored, or
returned.

5.  REMEDIES UPON EVENT OF DEFAULT

      Upon the occurrence of an Event of Default and the continuation of such
Event of Default, Agent may, subject to Section 8.5, declare all of the Guaranty
Liabilities, immediately and without demand, notice or legal process of any
kind, to be, and such Guaranty Liabilities shall immediately become, due and
payable, and then, or at any subsequent time, Agent may exercise for the benefit
of each Bank any or all of its rights and remedies under this Guaranty, the
Credit Agreement and any other Related Document, and under applicable law, and
may, in addition

            (a)  make demand upon Guarantor for the payment of the Guaranty
Liabilities; and

            (b)  resort to the Collateral for payment of the Guaranty
Liabilities, without notice, declaration, or demand by Agent to the extent not
prohibited by applicable law;


                                     -14-
<PAGE>


PROVIDED, that upon the occurrence of an Event of Default specified in clauses
(e) or (f) of Section 8.01 of the Credit Agreement, the Guaranty Liabilities
shall become immediately due and payable without declaration, notice or demand
by the Agent or any Bank.

6.    APPLICATION OF PAYMENTS

      Any payment made by Guarantor under this Guaranty shall be applied by
Agent first, to the satisfaction of Guarantor's indemnification liabilities
pursuant to Section 7; second, to the unreimbursed expenses of the Agent; third,
to then due interest on the Loans accrued and unpaid prior to the date such
payment is received by the Banks; and fourth, to reduce the principal balance of
the Loans.

7.    INDEMNIFICATION

      Guarantor agrees to indemnify and hold Agent and Banks harmless from and
against any Taxes, Other Taxes, liabilities, claims and damages, including
reasonable costs, attorneys' fees, and disbursements, and other expenses
incurred or arising by reason of the taking or the failure to take action by
Agent, in good faith, in respect of any transaction effected under this
Guaranty, including any action to enforce payment of the Guaranty Liabilities,
or in connection with the Lien upon the Collateral, including any Taxes or Other
Taxes payable in connection with the delivery of any of the Collateral as
provided herein and any action taken to protect, assert, or enforce the rights
or claims of the Agent or the Banks in any proceeding under the Bankruptcy Code.
The liabilities of Guarantor under this Section 7 shall survive the termination
of this Guaranty.

8.  MISCELLANEOUS

California Civil Code, if applicable, or otherwise) affect or impair the

to the Security Documents or the enforceability of the Notes and other
Obligations hereunder, and any attempted exercise by any Bank of any such right
without obtaining such consent of the Majority Banks shall be null and void.
This subsection (b) shall be solely for the benefit of each of the Banks
hereunder.

      8.14  PARTICIPATIONS; NOVATIONS.  Any Bank may from time to time,
without notice to the Guarantor and without affecting the Guarantor's
obligations hereunder, transfer its interest in the Obligations to Participants

to the Credit Agreement and this Guaranty.  The Guarantor authorizes the Agent

                                  INTRODUCTION


               The Board of Directors (the "Board") of Morrison Knudsen
Corporation, a Delaware corporation (the "Company"), has considered the effect
that recent events have had on employees of the Company and its subsidiaries
(collectively, the "Employer").  The Board recognizes and understands the
concern such employees have for their careers and their personal financial
security.  As a result, absent appropriate assurances, employees are likely to
seek more secure career opportunities, particularly if a reorganization or
restructuring transaction is proposed or threatened.

               This Plan is designed to enable such employees to make career
decisions without the time pressure and financial uncertainty which may result
from a proposed or threatened transaction, to encourage such employees to remain
employees of the Employer notwithstanding the outcome of any such proposed
transaction.

               As a result, the Board believes that this Plan will assist the
Company in attracting and retaining qualified employees.  Accordingly, the
following Plan is hereby adopted.

                                    ARTICLE I

                                   DEFINITIONS

               When used in this Plan and initially capitalized, the following
words and phrases shall have the following respective meanings unless the
context clearly requires otherwise:

<PAGE>

           1.1  "AWARD" shall mean an award granted pursuant to Section 4 of the
Plan.

           1.2  "BASE SALARY" as to any Covered Employee for any period, shall
mean (i) the base rate of salary paid to the Covered Employee by the Company at
the date of his or her inclusion in the Plan before reduction because of an
election between benefits or cash provided under a plan of the Company
maintained pursuant to Section 125 or 401(k) of the Internal Revenue Code of
1986, as amended, and before reduction for any other amounts contributed by the
Company on his or her behalf to any other employee-benefit plan or (ii) in the
event the Board acts to change the category in which the Covered Employee has
been placed, the base rate of salary paid to the Covered Employee by the
Employer (before any reductions provided in clause (i)) at the time the Board so
acts; PROVIDED, HOWEVER, that clause (ii) will not apply if its application
would adversely affect a Covered Employee's rights or benefits, contingent or
otherwise, under this Plan unless the Covered Employee consents to the
application of clause (ii).

directors of the Company.

demonstrably and materially injurious to the

Employer monetarily or otherwise.  For purposes of clauses (i) and (ii) of this
definition, no act, or failure to act, on the Employee's part shall be deemed
"willful" unless done, or omitted to be done, by the Employee not in good faith
and without reasonable belief that the Employee's act, or failure to act, was in
the best interest of the Employer.

           1.5  "CHANGE IN CONTROL OF THE BOARD" shall mean the event occurring
when, during any period of two consecutive years, individuals who at the
beginning of such period constituted the directors of the Company cease for any
reason to constitute a majority thereof (unless the election, or the nomination
for election by the Company's shareholders, of each director of the Company
first elected during such period was approved by a vote of at least two-thirds
of the directors then still in office who were directors of the Company at the
beginning of any such period).

           1.6  "COMPANY" shall mean Morrison Knudsen Corporation, a Delaware
corporation, or any entity that is a successor to Morrison Knudsen Corporation
in ownership of a majority of its assets.

New York Stock Exchange on such date, or if there are no reported sales on such
date, on the last preceding date on which sales were reported.  The Fair Market
Value determined by the Committee in good faith in such manner shall be final,
binding and conclusive on all parties.

           1.12 "INVOLUNTARY TERMINATION OF EMPLOYMENT" shall mean a termination
of employment with the Employer at the Employer's option other than for Cause.
An Involuntary Termination of Employment shall also occur upon the sale of

vest on July 1, 1996 if such Covered Employee is employed by the Employer on
such date; PROVIDED, HOWEVER, that:  (a) if a Covered Employee suffers an

4.3(a)(i) and 4.3(c)(i), as applicable, shall vest and such amounts shall
become immediately payable and (b) if a Covered Employee suffers an

Incentive Award.  The Covered Employee shall not be

           5.1  The Company shall have the right to withhold from amounts due
Participants or to collect from Participants directly, the amount which the
Company deems necessary to satisfy any taxes required by law to be withheld at
any time by reason of participation in the Plan and the obligations of the
Company under the Plan shall be conditional on payment of such taxes. The
Participant may, prior to the due date of any taxes, pay such amounts to the
Company in cash or, with the consent of the Committee, in Shares (which shall be
valued at their Fair Market Value on the date of payment). There is no
obligation under this Plan that any Participant be advised of the existence of
the tax or the amount required to be withheld. Without limiting the generality
of the foregoing, in any case where the Company determines that a tax is or will
be required to be withheld in connection with the issuance or transfer of Shares
under this Plan, the Company may, pursuant to such rules as the Committee may
establish, reduce the number of such Shares so issued or transferred by such
number of Shares as the Company may deem appropriate in its sole discretion to
accomplish such withholding or make such other arrangements as it deems
satisfactory. Notwithstanding any other provision of this Plan, the Committee
may impose such conditions on the payment of any withholding obligation as may
be required to satisfy applicable regulatory requirements.

provided to a Covered Employee (or his successor in interest) (unless such

                                  INTRODUCTION


          The Board of Directors (the "Board") of Morrison Knudsen Corporation,
a Delaware corporation (the "Company"), has considered the effect that recent
events have had on employees of the Company.  The Board recognizes and
understands the concern such employees have for their careers and their personal
financial security.  As a result, absent appropriate assurances, employees are
likely to seek more secure career opportunities, particularly if a
reorganization or restructuring transaction is proposed or threatened.

          This Plan is designed to enable such employees to make career
decisions without the time pressure and financial uncertainty which may result
from a proposed or threatened transaction, to encourage such employees to remain
employees of the Company notwithstanding the outcome of any such proposed
transaction, and to assure fair treatment of such employees in the event of a
corporate reorganization or restructuring.

          As a result, the Board believes that this Plan will assist the Company
in attracting and retaining qualified employees.  Accordingly, the following
Plan is hereby adopted.

                                    ARTICLE I

                                   DEFINITIONS

          When used in this Plan and initially capitalized, the following words
and phrases shall have the following respective meanings unless the context
clearly requires otherwise:

          1.1  "BASE SALARY" as to any Eligible Employee for any period, shall
mean (i) the base rate of salary paid to the


<PAGE>

Eligible Employee by the Company on the applicable Effective Date before
reduction because of an election between benefits or cash provided under a plan
of the Company maintained pursuant to Section 125 or 401(k) of the Internal
Revenue Code of 1986, as amended, and before reduction for any other amounts
contributed by the Company on his or her behalf to any other employee benefit
plan or (ii) in the event that the Committee acts to change the category under
Section 3.1 in which an Eligible Employee has been placed, the base rate of
salary paid to the Eligible Employee by the Employer (before any reductions
listed in clause (i)) at the time the Committee so acts; PROVIDED, HOWEVER, that
clause (ii) will not apply if its application would adversely affect an Eligible
Employee's rights or benefits, contingent or otherwise, under this Plan.

          1.2  "CAUSE" for termination by the Company, shall mean termination by
the Company for (i) the willful and continued failure by the Employee to
substantially perform the Employee's duties with the Company (other than any
such failure resulting from the Employee's incapacity due to physical or mental
illness) or (ii) the willful engaging by the Employee in conduct which is
demonstrably and materially injurious to the Company monetarily or otherwise.
For purposes of clauses (i) and (ii) of this definition, no act, or failure to
act, on the Employee's part shall be deemed "willful" unless done, or omitted to
be done, by the Employee not in good faith and without reasonable belief that
the Employee's act, or failure to act, was in the best interest of the Company.

     corporations or entities, in a single transaction or a series of related
     transactions, more than one-half of the voting shares or assets of any
     business unit, division or subsidiary of the Company, unless by an
     affirmative vote of two-thirds of the members of the Board of Directors,
     the transaction or transactions are exempted from the operation of this
     provision based on a good faith finding that the transaction or
     transactions are not within the intended scope of this definition for
     purposes of this instrument; or

               (b)  The filing of a petition of bankruptcy under Title 11 of the
     United States Code.

               (c)  If during any period of two consecutive years, individuals
who at the beginning of such period constituted the directors of the Company
cease for any reason to constitute a majority thereof (unless the election, or
the nomination for election by the Company's shareholders, of each director of
the Company first elected during such period was approved by a vote of at least
two-thirds of the directors then still in office who were directors of the
Company at the beginning of any such period).

          1.7  "ELIGIBLE EMPLOYEE" shall mean an employee of the Company as
provided in Section 2.1 hereof.

          1.8  "INVOLUNTARY TERMINATION OF EMPLOYMENT" shall mean a termination

other than for Cause; and in the event an Effective Date arises pursuant to
Section 1.6(a)  and the (i)Purchaser does not offer Employee employment with
comparable responsibility, pay and benefits provided to Employee while engaged
in employment at the Company or (ii)Purchaser has terminated the employee for a
reason other than Cause and such termination occurs within one year following
the occurrence of the Effective Date under 1.6(a).  Employee shall be deemed to
have received comparable  pay if Purchaser offers Employee an annual base salary

the occurrence of the Effective Date arising pursuant to Section 1.6(a).

          1.9  "PLAN" shall mean this Morrison Knudsen Corporation Retention

(listed on Schedule A of this Plan) of any other division, business unit or
subsidiary that is sold.

          6.1  IN GENERAL.  The Plan shall be administered by the Company, which
hereby delegates to the Committee all administrative duties, including without
limitation duties with respect to the processing, review, investigation,
approval, and payment of benefits under the Plan.  The Committee shall be the
named fiduciary under the Plan.  The Committee shall have the sole and absolute
discretion to interpret where necessary all provisions of the Plan (including,
without limitation, by supplying omissions from, correcting deficiencies in, or
resolving inconsistencies or ambiguities in, the language of the Plan), to
determine the rights and status under the Plan of


                                        7

<PAGE>

Eligible Employees, Covered Employees or other persons, to resolve questions or
disputes arising under the Plan and to make any determinations with respect to
the benefits payable hereunder and the persons entitled thereto as may be
necessary for the purposes of the Plan.  Without limiting the generality of the
foregoing, the Committee is hereby granted the authority to determine whether a
particular employee is an Eligible Employee or Covered Employee.

          6.2  REGULATIONS.  The Committee shall promulgate any rules and
regulations that it deems necessary to carry out the purposes of the Plan, or to
interpret the terms and conditions of the Plan; provided that no rule,
regulation, or interpretation shall be contrary to the provisions of the Plan.
The rules, regulations, and interpretations made by the Committee shall, subject
only to the claims procedure outlined in Section 6.3 hereof, be final and
binding on any employee or former employee of the Company, or any successor in
interest of either.

          6.3  CLAIMS PROCEDURE.  The Committee shall determine the rights of
any employee or former employee of the Company to any benefits hereunder.  Any
employee or former employee of the Company who believes that he or she is
entitled to receive any benefits other than as initially determined by the
Committee, may  file a claim in writing with the Committee.  The Committee shall
no later than 60 days after the receipt of a claim either allow or deny the
claim in writing.

          A denial of a claim, wholly or partially, shall be written in a manner
calculated to be understood by the claimant and shall include:


                                        8

<PAGE>

               (a)  the specific reason or reasons for the denial;

               (b)  a specific reference to pertinent Plan provisions on which
                    the denial is based;

               (c)  a description of any additional material or information
                    necessary for the claimant to perfect the claim and an
                    explanation of why such material or information is
                    necessary; and

               (d)  an explanation of the claim-review procedure.

          A claimant whose claim is denied (or his duly authorized
representative) may, within 60 days after receipt of denial of his or her claim:

          (a)  request a review upon written application to Human Resources;

          (b)  review pertinent documents; and

          (c)  submit issues and comments in writing.

          The Committee shall notify the claimant of its decision on review
within 60 days after receipt of a request for review.  Notice of the decision on
review shall be in writing.

          6.4  REVOCABILITY OF COMMITTEE ACTION.  Any action taken by the
Committee with respect to the rights under the Plan of any  employee or former
employee shall be revocable by the Committee as to payments or distributions not
yet made to such person, and acceptance of any benefits under the Plan
constitutes acceptance of and agreement to any appropriate adjustments made by
the Committee in future payments or distributions to such


                                        9

<PAGE>

person to offset any excess or underpayment previously made to him or her with
respect to any benefits.

                                   ARTICLE VII

                        AMENDMENT OR TERMINATION OF PLAN

          7.1  RIGHT TO AMEND OR TERMINATE.  The Company, by resolution adopted
by a majority of the members of the Board, reserves the right at any time prior
to an Effective Date, and without prior or other approval of any employee or
former employee, to change, modify, amend, or terminate the Plan.  All such
changes, modifications, or amendments may be retroactive to any date and shall
be retroactive to that date unless some other provision is specifically made.
Following the Effective Date, except as may be required by law, this Plan shall
not be amended without the consent of the Eligible Employees, unless such
amendment will not adversely affect the Eligible Employees.  An amendment of
this Plan shall automatically effect a corresponding amendment to the rights of
all Covered Employees under this Plan.

          7.2  AUTOMATIC TERMINATION.  This Plan will terminate automatically as
of July 1, 1996, if there is no Effective Date prior to that date. Termination
pursuant to this Section 7.2 shall occur without any action on the part of the
Company and shall be effective without prior notice to or approval of any
employee or former employee of the Company.

                                  ARTICLE VIII

                                METHOD OF FUNDING

          8.1  PLAN IS NOT FUNDED.  The Company shall pay benefits under the
Plan from its general assets.  No property of



                                       10

<PAGE>

the Company is or shall be, by reason of this Plan, held in trust for any
employee of the Company, nor shall any person have any interest in or any lien
or prior claim upon any property of the Company by reason of the Plan or the
Company's obligations to make payments hereunder.

                                   ARTICLE IX

                           CONFIDENTIALITY AND RELEASE

           9.1  CONFIDENTIALITY.  Payment of the Severance Pay set forth in
Article III hereof to or for the benefit of a Covered Employee is conditioned
upon the Covered Employee agreeing in writing with the Company that all trade
secrets, customer lists, and other confidential business information are the
exclusive property of the Company and that the Covered Employee shall not at any
time reveal or cause to be revealed to any person or entity such trade secrets,
customer lists and other confidential business information obtained as a result
of such Covered Employee's employment or relationship with the Company.

          9.2  RELEASE.  Payment of the severance pay and provision of the
benefits set forth in Article III hereof to or for the benefit of a Covered
Employee is conditioned upon the Covered Employee executing and delivering a
release satisfactory to the Company releasing the Company from any and all
claims, demands, damages, actions and/or causes of action whatsoever, which he
or she may have had on account of the termination of his or her employment,
including, but not limited to claims of discrimination, including on the basis
of sex, race, age,


                                       11

<PAGE>

national origin, religion, or handicapped status (with all applicable periods
during which the Covered Employee may revoke the release or any provision
thereof having expired), and any and all claims, demands and causes of action
for retirement (other than under any "pension benefit plan" or under any
"welfare benefit plan" of the Company (as those terms are defined in Sections
3(1) and 3(2) of the Employee Retirement Income Security Act of 1974, as
amended)), severance pay (other than under a "welfare benefit plan") or other
termination pay.  Such release shall not, however, apply to the ongoing
obligations of the Company arising under this Plan, or rights of indemnification
the Covered Employee may have under the Company's By-laws or by contract or by
statute.

                                                  EXHIBIT 10.1

                              FORBEARANCE AGREEMENT


          This Forbearance Agreement (the "Agreement") is entered into this 30
day of June, 1995, among MELLON BANK, N.A., ("Mellon"), UNITED STATES NATIONAL
BANK OF OREGON ("USNB"), EMKAY DEVELOPMENT COMPANY, INC. ("Emkay") and MORRISON
KNUDSEN CORPORATION, a Delaware corporation ("Morrison").

                                    RECITALS

          A.   Emkay is indebted to Mellon pursuant to a promissory note dated
December 15, 1994, in the original principal amount of $20,180,000 (the "Mellon
Note").  As of June 30, 1995, Emkay owed Mellon the principal amount of
$20,180,000 and accrued interest of $182,449.32 pursuant to the Mellon Note.

          B.   Emkay is indebted to USNB pursuant to a promissory note dated
December 8, 1994, (the "USNB Note") in the original principal amount of
$10,897,963.11.  As of June 30, 1995, Emkay owed USNB the principal amount of
$10,897,963.11 and accrued interest (computed at USNB's prime rate of interest
since March 14, 1995) of $296,969.49 pursuant to the USNB Note.

          C.   The amounts due under the Mellon Note and the USNB Note are
collectively referred to as the "Loans."  Those notes, Morrison's guaranties
with respect thereto, and any loan agreements or other documents related to the
Loans are referred to below collectively as the "Existing Loan Documents."

          D.   Payment of the obligations of Emkay to Mellon and USNB with
respect to the Loans is guaranteed unconditionally by Morrison.

          E.   Interest continues to accrue on the promissory notes described
above on and after July 1, 1995, and is due and owing by Emkay to Mellon and
USNB (the "Banks") in addition to the amounts specified above.  In addition,
Emkay is obligated to reimburse the Banks for certain attorney fees and costs
incurred by the Banks.

          F.   Emkay is in default on the Loans as a result of Emkay's failure
to pay the Loans as agreed.  The defaults described in the preceding sentence
and any other defaults on the Loans or under the Existing Loan Documents as of
the date of this Agreement, whether or not such defaults are known to the Banks,
are referred to below collectively as the "Existing Defaults."

          G.   Emkay and Morrison have requested the Banks to forbear from
exercising the Banks' rights and remedies against Emkay and Morrison as a result
of the Existing Defaults.  The


                                      - 1 -

<PAGE>

Banks are willing to do so, subject to the terms and conditions of this
Agreement.

                              TERMS AND CONDITIONS

          NOW, THEREFORE, in consideration of the mutual covenants contained in
this Agreement and for other good and valuable consideration, the receipt and
sufficiency of which hereby are acknowledged, the parties to this Agreement
agree as follows:

                                    SECTION I

                           PAYMENT OF THE OBLIGATIONS

          1.1  CONDITIONAL AGREEMENT TO FORBEAR.  The Banks hereby agree to
forbear from exercising their existing rights and remedies against Emkay and
Morrison with respect to the Loans (and Morrison's guaranties of the Loans) as a
result of the Existing Defaults until the earlier of (a) June 30, 1996; or
(b) the occurrence of an Event of Default (as defined in paragraph 7.1 of this
Agreement).

          1.2  ACKNOWLEDGMENT OF AMOUNTS OWED WITH RESPECT TO THE EXISTING
NOTES.  Emkay and Morrison hereby acknowledge and agree that the entire amounts
of principal and interest specified in the Recitals to this Agreement are due
and payable to the Banks and, except with respect to the counterclaims asserted
by Emkay and Morrison against USNB in the Litigation (as defined in paragraph
4.1 of this Agreement), are not subject to any offset, defense, counterclaim, or
claim of recoupment by Emkay or Morrison, or either of them.  Furthermore, Emkay
and Morrison acknowledge the accuracy of the other recitals to this Agreement.
Emkay and Morrison acknowledge and agree that, contemporaneously with the
execution of this Agreement, which includes the release specified in
paragraph 4.3 below, the above-described counterclaims against USNB are released
and dismissed and the entire amount of principal and interest specified in
Recital B to this Agreement is due and owing to USNB without offset, defense,
counterclaim, or claim of recoupment.

          1.3  REAFFIRMATION OF GUARANTIES.  Morrison hereby reaffirms its
obligations to the Banks under its guaranties to unconditionally guarantee
prompt payment and performance of Emkay's obligations with respect to the Loans.


          1.4  PAYMENT OF ACCRUED INTEREST, COSTS, AND ATTORNEY FEES.  On the
date of execution of this Agreement, Emkay shall pay to Mellon and USNB all
accrued but unpaid interest as of the date of this Agreement pursuant to the
Mellon Note and the USNB Note, respectively.  In addition, on the date of
execution of this Agreement, Emkay shall reimburse the Banks for all reasonable
costs and expenses, including reasonable attorney fees, incurred by either of
the Banks to the date of this Agreement


                                      - 2 -

<PAGE>

in connection with the negotiation and documentation of this Agreement and the
transactions contemplated by this Agreement (but specifically excluding any
attorney fees incurred by USNB in connection with the Litigation).  The Banks
shall provide Emkay with reasonably detailed evidence of such attorney fees.

          1.5  APPLICABLE INTEREST RATES.  Except as specified in the following
sentence, the rate of interest applicable to amounts owed by Emkay pursuant to
the Mellon Note and the USNB Note on and after the date of this Agreement shall
be Mellon's publicly announced prime rate (fully floating) and USNB's publicly
announced prime rate (fully floating), respectively.  Nothing herein shall
affect, alter, or impair the Banks' rights to charge Emkay the default rates of
interest specified in the Mellon Note and the USNB Note (as applicable)
following an Event of Default.

          1.6  PAYMENT OF THE NOTES.  On July 5, 1995, and the same day of each
month thereafter through and including June 1996, Emkay shall pay Mellon and
USNB an amount equal to interest accrued through the last day of the preceding
month on the Mellon Note and the USNB Note, respectively.  The entire unpaid
balance of principal and interest owed to Mellon on the Mellon Note and to USNB
on the USNB Note shall be due and payable by Emkay on June 30, 1996 (the
"Maturity Date"), subject to the right of Mellon and USNB (or either of them) to
accelerate the amounts owed pursuant to those notes prior to the Maturity Date
upon the occurrence of an Event of Default.  The Notes may be prepaid at any
time without premium or penalty.

          1.7  ONGOING EXPENSES OF THE BANKS.  Emkay shall reimburse the Banks
for all necessary expenses reasonably incurred by the Banks on and after the
date of this Agreement, including, but not limited to, recording charges, escrow
charges, travel expenses, appraisal costs, environmental survey and
investigation costs, collateral examination and inspection costs, and the
reasonable fees and expenses of legal counsel for the Banks (including in-house
legal counsel), in connection with (a) the preparation, negotiation, closing,
administration, amendment, modification, and enforcement of this Agreement, or
the agreement evidenced hereby; (b) the valuation, evaluation, preservation, or
protection of the Collateral (as that term is defined in paragraph 2.1 of this
Agreement) (or the Banks' security interests therein); or (c) actions taken as
required by applicable law, rules, regulations, and policies.  Except as
provided in Section 2.3 of this Agreement, the amounts owed by Emkay pursuant to
the preceding sentence of this Agreement shall be paid by Emkay to the bank in
question within ten days of the date Emkay receives a bill (which may be sent by
facsimile transmission and shall be deemed to have been received by Emkay upon
completion of such transmission) from Mellon or USNB for such amounts, with
adequate detail supporting the billing.  If


                                      - 3 -

<PAGE>

Emkay fails to pay all or any portion of the amounts referred to in the
preceding sentence, such unpaid amounts shall be due and owing to the Banks (or
such bank as is not paid), together with interest thereon at the default rate
specified in the applicable promissory note from the date Emkay received the
bill therefor, until paid.

          1.8  ATTORNEY FEES.  Without limiting the meaning of the term
"enforcement" as used in the preceding paragraph of this Agreement, if the Banks
(or either of them) incur any attorney fees (including those of in-house
counsel) in any action, suit, or bankruptcy case or proceeding in relation to or
involving this Agreement, the Security Agreements, or any other instrument or
agreement between or among the parties to this Agreement (or any of them) or any
appeal of any of the foregoing, in which the Banks (or either of them) are the
prevailing party, such bank or banks in addition to all other sums that the
other party may be called upon to pay, shall be entitled to recover the
prevailing party's reasonable attorney fees incurred therein.

          1.9  INTERCREDITOR AGREEMENT.  The Banks will enter into such
intercreditor agreement, collateral agency agreement, and other agreements that
the Banks believe are necessary to provide for a pro rata sharing of all income
and proceeds from the Collateral and perfection and protection of their security
interests and liens in the Collateral.  Emkay and Morrison shall take any
actions reasonably requested by the Banks that will facilitate the Banks'
agreement to share the Collateral and the proceeds thereof on a pro rata basis.
The pro rata sharing between the Banks shall be computed in accordance with the
principal balances owed with respect to the Mellon Note and the USNB Note as of
the date of this Agreement, which means that Mellon's share of pro rata payments
and expenses is 64.9335 percent and USNB's share thereof is 35.0665 percent (the
"Pro Rata Shares").

          1.10  CONTINUED VALIDITY OF AGREEMENTS.  Emkay and Morrison hereby
expressly acknowledge and agree that the Mellon Note and any related documents,
the USNB Note and any related documents, Morrison's guaranties with respect to
those notes, and any other agreements between or among the parties to this
Agreement (or any of them), are valid, binding agreements and are enforceable
against Emkay and Morrison (as applicable) in accordance with the terms of those
agreements, except to the extent expressly modified or amended by this
Agreement.  The Banks' forbearance hereunder is only with respect to the
Existing Defaults and does not apply or extend to an Event of Default hereunder,
or to any default under any other agreements between or among the parties to
this Agreement.

                                   SECTION II

                         COLLATERAL FOR THE OBLIGATIONS

          2.1  GRANTING OF SECURITY INTERESTS.  Contemporaneously with the
execution of this Agreement, Emkay shall execute and deliver to the Banks such
security agreements, trust deeds, or other documents (the "Security Agreements")
that the Banks reasonably believe are necessary or desirable to grant the Banks
security interests and liens in or with respect to all existing and after-
acquired assets of Emkay, including all income and rents from such assets and
all proceeds of the sale or other disposition of all such assets.  The assets
that are the subject of the Banks' security interests and liens described in the
preceding sentence (including all proceeds thereof) are referred to in this
Agreement collectively as the "Collateral."

          2.2  OTHER DOCUMENTS.  Emkay hereby agrees that until the Mellon Note
and the USNB Note have been paid in full, Emkay promptly shall execute and
deliver to the Banks all documents reasonably deemed necessary or desirable by
the Banks to create, evidence, perfect, or continue their security interests or
liens in the Collateral.

          2.3  APPRAISALS AND ENVIRONMENTAL REPORTS.  Emkay promptly will take
any and all action reasonably requested by the Banks (or either of them) that
the Banks believe is necessary or desirable to enable the Banks to obtain
appraisals and environmental reports on all real property owned by Emkay, or
subject to any interest, claim, or right of Emkay.  The determination of whether
it is necessary or desirable to obtain appraisals and environmental reports will
be made by the Banks (or either of them) in their good faith discretion, but
will consider, among other things, whether the real property or the assets of
Emkay related to the real property is subject to a pending disposition by Emkay.
Emkay hereby agrees that costs incurred by the Banks with respect to appraisals
and environmental studies shall be added to the obligations of Emkay to the
Banks with respect to the Loans and shall be paid by Emkay on or before the
maturity of the Loans.

          2.4  CERTIFICATION REGARDING ASSETS.  Prior to or contemporaneously
with the execution of this Agreement, Emkay shall deliver to the Banks a written
list of all assets of Emkay having a book or market value of $10,000, or more.

          2.5  THE BANKS' RIGHT TO INSPECT THE COLLATERAL.  Emkay hereby agrees
that the Banks (or either of them) may inspect all or any portion of the
Collateral at any reasonable time on reasonable advance notice to Emkay.
Notwithstanding the foregoing, after an Event of Default hereunder, the Banks
(or either of them) may take any action permitted by law at any time,


                                      - 5 -

<PAGE>

with or without notice to, or the permission of, Emkay or Morrison.

                                   SECTION III

                             THE LIQUIDATION PROCESS

          3.1  THE SALES AGENT.  On or before July 10, 1995, Emkay will retain a
sales agent (the "Sales Agent") reasonably acceptable to the Banks on terms
reasonably acceptable to the Banks.  The Sales Agent will be authorized and
directed by Emkay to obtain offers to purchase, or otherwise arrange sales of,
in each case subject to approval by Emkay's Board of Directors, Emkay's
interests in the Collateral on or before June 30, 1996.

          3.2  ASSET LIQUIDATION PROGRAM.  On or before July 17, 1995, Emkay,
with the assistance of the Sales Agent, shall develop and deliver to the Banks a
plan for the liquidation of the Collateral (the "Liquidation Plan") by June 30,
1996, which plan must be reasonably acceptable to the Banks.  At the same time,
Emkay and the Sales Agent shall deliver to the Banks a budget setting forth the
projected income and expenses relating to the proposed plan for the liquidation
of Emkay's assets (the "Liquidation Budget"), which budget must be reasonably
acceptable to the Banks.  The Banks acknowledge that the Liquidation Plan may
reflect that proceeds resulting from the liquidation of the Collateral may be
insufficient to pay the Loans in full and agree that such fact, in and of
itself, shall not cause the Liquidation Plan to be unacceptable to the Banks.

          3.3  THE EMKAY CASH COLLATERAL ACCOUNT.  All proceeds of the
Collateral, including rents, profits, other revenue or payments, and proceeds
resulting from the sale or disposition of all or any portion of the Collateral,
shall be deposited into an account maintained by Emkay at USNB (the "Emkay Cash
Collateral Account").  Prior to or contemporaneously with the execution of this
Agreement, Emkay shall grant the Banks security interests and liens in the Emkay
Cash Collateral Account and all funds now or hereafter in that account.

          3.4  USE OF FUNDS IN THE EMKAY CASH COLLATERAL ACCOUNT.  Funds on
deposit in the Emkay Cash Collateral Account may be used by Emkay only for the
following purposes:

               (a)  To pay the reasonable expenses of Emkay incurred in
          connection with the preservation, protection, and liquidation of the
          Collateral; and

               (b)  To pay the obligations owing by Emkay to the Banks pursuant
          to the Loans and this Agreement.

Proceeds of the Collateral, including funds in the Emkay Cash Collateral
Account, may not be paid, transferred, delivered, or


                                      - 6 -

<PAGE>

otherwise given to or received by Morrison until Emkay has paid in full its
obligations to the Banks pursuant to the Loans and this Agreement.  Accordingly,
Morrison shall not be reimbursed by Emkay (or with proceeds of the Collateral)
for support services, if any, provided by Morrison to Emkay until Emkay has paid
in full its obligations to the Banks pursuant to the Loans and this Agreement.

          3.5  MANDATORY DISTRIBUTION OF AMOUNTS IN THE EMKAY CASH COLLATERAL
ACCOUNT.  Unless the parties to this Agreement agree in writing to a different
schedule for disbursement, the entire balance of funds in the Emkay Cash
Collateral Account, except for such amount that must reasonably be retained to
fund payment of the items discussed in paragraph 3.4 above, shall be disbursed
to the Banks (according to their Pro Rata Shares) on the last day of each month
following the date of this Agreement.  Notwithstanding the foregoing, all
amounts in the Cash Collateral Account shall be disbursed to the Banks according
to their Pro Rata Shares immediately after the occurrence of an Event of
Default.

          3.6  LIMIT ON VARIANCE FROM THE LIQUIDATION BUDGET.  Emkay's
expenditures with respect to the matters identified in paragraph 3.4(a) above
shall not exceed the expenses projected in the Liquidation Budget by more than
10 percent, measured on an aggregate basis from the date of this Agreement.

          3.7  LIEN RELEASE MECHANISM.  The Banks agree that they shall consent
to a sale by Emkay of all or any portion of the Collateral (and shall release
their liens and security interests in the asset or assets in question upon
Emkay's compliance with paragraph 3.3 of this Agreement) that would result in
payment in cash to Emkay on or before June 30, 1996, in an amount equal to or
greater than the price specified in the Liquidation Plan for the asset or assets
in question, provided that such sale is evidenced by a binding, written
agreement and is to a buyer that is determined by the Sales Agent to be ready,
willing, and able to close the transaction.  If Emkay proposes to sell all or
any portion of the Collateral for an amount less than specified in the
Liquidation Plan (or the sale is proposed prior to delivery of the Liquidation
Plan to the Banks and approval by the Banks thereof), and the terms of such
proposed sale or sales constitute a Recommended Sale (as defined in the
following sentence), and the Banks do not consent to such sale and do not agree
to release their liens or security interests in the asset or assets in question
upon Emkay's compliance with paragraph 3.3 of this Agreement, then, in the event
that a subsequent sale of the asset or assets in question results in less
proceeds paid to Emkay than the proceeds that would have been received by Emkay
if the Recommended Sale had closed, Emkay shall receive a credit against the
amount owed with respect to the Loans (which shall be allocated between the
loans in accordance with the Banks' Pro Rata Shares) equal to the difference
between the proceeds actually received by Emkay from the sale of the asset or
assets


                                      - 7 -

<PAGE>

in question and the proceeds Emkay would have received if the Recommended Sale
had closed.  The term "Recommended Sale" as used in this Agreement means a sale
of all or any portion of the Collateral that has been recommended by the Sales
Agent and approved by Emkay's Board of Directors that would result in payment of
the agreed-upon purchase price in cash on or before June 30, 1996, pursuant to a
binding, written agreement by a buyer that is determined by the Sales Agent to
be ready, willing, and able to close the transaction.

               (ii)  No material adverse change has occurred in the

                                   SECTION VI

                         REPRESENTATIONS AND WARRANTIES

          6.1  GENERAL REPRESENTATIONS, WARRANTIES, AND COVENANTS.  To induce
the Banks to enter into this Agreement, Emkay and Morrison represent and warrant
to the Banks as follows:

          (a)  Emkay and Morrison are duly organized and existing under the
     laws of the states of Nevada and Delaware, respectively.  Emkay and
     Morrison have the power to own their property and carry on their
     businesses as now being conducted.  Furthermore, Emkay and Morrison
     are duly qualified and authorized to do business and are in good
     standing in every state, county, or other jurisdiction in which the
     nature of their properties and businesses make such qualification
     necessary and where the failure to so qualify and remain in good
     standing would have a material adverse effect on their ability to


                                     - 11 -

<PAGE>

     own their property or carry on their businesses as now being conducted;

          (b)  Emkay and Morrison are authorized to execute, deliver, and
     perform this Agreement, and any other instrument, document, or
     agreement required hereunder.  The execution, delivery, and
     performance by Emkay and Morrison (or either of them) of this
     Agreement, the Security Agreements, and the other documents,
     instruments, or agreements referred to herein does not contravene any
     law, the terms of the charter, bylaws or other incorporation papers of
     Emkay and Morrison, or any indenture, agreement, or undertaking to
     which Emkay or Morrison is a party, or by which Emkay or Morrison is
     bound;

          (c)  The officers of Emkay and Morrison who execute this
     Agreement, the Security Agreements, or any other instrument, document,
     or agreement required hereunder to be executed by Emkay or Morrison,
     are duly and properly in office and fully authorized to execute the
     same;

          (d)  Emkay has filed all tax returns required by law to be filed
     and have paid and will pay in a timely fashion all taxes, assessments,
     and other governmental charges, including, but not limited to,
     employment taxes, withholding taxes, income taxes, and taxes levied
     upon any of their property, assets, or income, other than those not
     yet delinquent and those not substantial in aggregate amount and being
     or about to be contested in good faith by appropriate means;

          (e)  Emkay shall maintain fire and public liability insurance
     with respect to its properties and operations in such coverage
     amounts, deductibles, and other terms, and with such insurers, as are
     reasonably acceptable to the Banks;

          (f)  Emkay shall maintain insurance with an insurer and in amount
     reasonably satisfactory to the Banks with respect to the Collateral
     (which amount shall be at least equal to the greater of the aggregate
     amount of the Loans, or the amount specified in any co-insurance
     clause in any applicable insurance policy at which Emkay does not bear
     any portion of the risk of loss (other than the deductible amount
     specified in the policy) for either a partial or total destruction of
     the insured property) until such time as Emkay has satisfied fully its
     obligations with respect to the Loans; provided, however, that nothing
     herein shall obligate Emkay to insure the Collateral for more than its
     insurable value.  Each policy of insurance shall bear a lender's loss
     payable endorsement in a form satisfactory to the Banks naming


                                     - 12 -

<PAGE>

     the Banks as loss payee, or otherwise insuring and protecting the Banks'
     interest in the property.  Notwithstanding anything in this Agreement or
     any of the Security Agreements to the contrary, Emkay shall have no
     obligation to maintain fire insurance with respect to bare land.  Prior to
     or contemporaneously with the date of this Agreement, Emkay shall provide
     the Banks evidence that they have obtained insurance as described herein;
     and

          (g)  All information, reports, and other papers and data
     furnished by Emkay or Morrison to the Banks are, to the best of
     Emkay's and Morrison's knowledge, based upon reasonable investigation,
     at the time such documents are provided to the Banks, complete and
     correct in all material respects to the extent necessary to give the
     Banks true and accurate information regarding the subject matter
     thereof.

                                   SECTION VII

                              DEFAULT AND REMEDIES

          7.1  EVENTS OF DEFAULT.  The occurrence of any of the following events
("Event(s) of Default") shall constitute a default by Emkay and Morrison under
this Agreement and the notes and guaranties referred to above:

          (a)  FAILURE TO PAY.  Emkay fails to pay any amount owed to the
     Banks pursuant to either the Mellon Note or the USNB Note, within ten
     (10) days after written notice that such amount is due;

          (b)  FAILURE TO PAY ATTORNEY FEES AND COSTS.  Emkay fails to pay
     any of the Banks' attorney fees, costs, and expenses as required by
     paragraph 1.7 of this Agreement;

          (c)  FAILURE TO DEPOSIT PROCEEDS.  Emkay fails to deposit or
     cause to be deposited any proceeds of the Collateral into the Emkay
     Cash Collateral Account;

          (d)  FAILURE TO APPOINT SALES AGENT OR DELIVER LIQUIDATION PLAN.
     Emkay fails to retain the Sales Agent, or to deliver the Liquidation
     Plan and the Liquidation Budget to the Banks as required by
     paragraphs 3.1 and 3.2, respectively, of this Agreement;

          (e)  FAILURE TO COMPLY WITH OTHER OBLIGATIONS.  Emkay fails to
     comply with any other covenant, agreement, term, or condition imposed
     upon Emkay by this Agreement, the Security Agreements, or any other
     agreement with the Banks pertaining to the Loans executed by Emkay on
     or after the date of this Agreement, and does not remedy or


                                     - 13 -

<PAGE>

     cure such failure within thirty (30) days following written notice from the
     Banks of such failure (notwithstanding the foregoing, the Existing Defaults
     shall not constitute an Event of Default under this Agreement);

          (f)  INCORRECT OR MISLEADING STATEMENT.  Any material statement,
     representation, or warranty made by Emkay or Morrison in this
     Agreement or in any written statement furnished to the Banks in
     connection with this Agreement, whether contemporaneously with or
     subsequent to the delivery of this Agreement, proves to have been
     incorrect or misleading in any material respect when made; or

          (g)  RECEIVERSHIP/BANKRUPTCY.  A receiver or trustee is appointed
     for Emkay or Morrison, or for any substantial part of any of their
     assets, or any bankruptcy case is instituted by or with respect to
     Emkay or Morrison.

          7.2  ACCELERATION.  At the option of the Banks (or either of them),
upon the occurrence of any Event of Default, all of the obligations of Emkay and
Morrison to the Banks under this Agreement and the promissory notes and
guaranties described in this Agreement immediately shall become due and payable.

          7.3  REMEDIES.  Following the occurrence of an Event of Default, the
Banks (or either of them) immediately and without notice to Emkay or Morrison
may exercise any or all of their rights and remedies under this Agreement, the
promissory notes, the guaranties, the Security Agreements, any other agreements
between or among the parties, and applicable law, all of which rights and
remedies are cumulative.

          8.4  SEVERABILITY.  If any term, condition, or provision of this
Agreement, or any other document or instrument referred to in this Agreement, is
held invalid for any reason, such offending term, condition, or provision shall
be stricken therefrom, and the remainder thereof shall not be affected thereby.

          8.5  AMENDMENTS.  This Agreement may be amended or modified only by a
written agreement signed by an authorized representative of Emkay, Morrison, and
the Banks that by its terms expressly supersedes, modifies, amends, or alters
this Agreement.

          8.6  NEGOTIATED AGREEMENT.  This Agreement is a negotiated agreement.
In the event of any ambiguity in this Agreement, such ambiguity shall not be
subject to a rule of


                                     - 15 -

<PAGE>

contract interpretation that would cause the ambiguity to be construed against
any of the parties to this Agreement.

          8.7  VOLUNTARY AND ENTIRE AGREEMENT.  The only consideration for the
execution of this Agreement is the consideration expressly recited herein.  This
Agreement and the other agreements and instruments referred to in this Agreement
set forth and constitute the entire agreement among the parties hereto with
respect to the subject matter of this Agreement.  No oral promise or agreement
of any kind or nature, other than those that have been reduced to writing and
set forth herein, has been made between or among the Banks and any of the other
parties to this Agreement.  Emkay and Morrison acknowledge that they have been
represented by legal counsel in connection with the negotiation and execution of
this Agreement and the other agreements and instruments referred to in this
Agreement.  Emkay and Morrison voluntarily executed this Agreement and the other
agreements and instruments referred to in this Agreement.

          8.8  CONSTRUCTION AND CONFLICT WITH OTHER AGREEMENTS.  In the event of

          8.9  WAIVERS.  No waiver of any provision of this Agreement, the
promissory notes, the Security Agreements, the guaranties, or any other
agreement between or among the parties hereto, nor consent to any failure by
Emkay or Morrison to comply with such provisions, shall be effective unless the
same shall be in writing and signed by the Banks, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given.

          8.10 APPLICABLE LAW.  This Agreement and any other instrument or
agreement required or contemplated hereunder shall be governed by, and construed
under, the laws of the state of Oregon without regard to principles of conflicts
of law.
