States and the District of Columbia, but excluding its territories and
possessions.

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

        SECTION 1.02, Accounting Terms and Determinations.  Unless otherwise
specified herein, all accounting terms used herein shall be interpreted, all
accounting determinations hereunder shall be made, and all financial statements
required to be delivered hereunder shall be prepared in accordance with
generally accepted accounting principles as in effect from time to time,
applied on a basis consistent (except for changes concurred in by the Company's
independent public accountants) with the most recent audited consolidated
financial statements of the Company and its Consolidated Subsidiaries delivered
to the Banks; provided that, if the Company notifies the Agent that the Company
wishes to amend any covenant in Article V to eliminate the effect of any change
in generally accepted accounting principles on the operation of such covenant
(or

                                       14
<PAGE>   20
if the Agent notifies the Company that the Required Banks wish to amend
Article V for such purpose), then the Company's compliance with such covenant
shall be determined on the basis of generally accepted accounting principles in
effect immediately before the relevant change in generally accepted accounting
principles became effective, until either such notice is withdrawn or such
covenant is amended in a manner satisfactory to the Company and the Required
Banks.

         SECTION 1.03.  Types of Borrowings.  The term "Borrowing" denotes the
aggregation of Loans of one or more Banks to be made to a Borrower pursuant to
Article II on a single date and for a single Interest Period.  Borrowings are
classified for purposes of this Agreement either by reference to the pricing of
Loans comprising such Borrowing (e.g., a "Euro-Dollar Borrowing" is a Borrowing
comprised of Euro-Dollar Loans) or by reference to the provisions of Article II
under which participation therein is determined (i.e., a "Committed Borrowing"
is a Borrowing under Section 2.01 in which all Banks participate in proportion
to their Commitments, while a "Money Market Borrowing" is a Borrowing under
Section 2.03 in which the Bank participants are determined on the basis of
their bids in accordance therewith).


                                   ARTICLE II

                                  THE CREDITS


         SECTION 2.01. Commitments.

         (a)     Commitments to Lend.  From time to time prior to its
Termination Date, each Bank severally agrees, on the terms and conditions set
forth in this Agreement, to make loans to either Borrower pursuant to this
Section from time to time in amounts such that the aggregate principal amount
of Committed Loans by such Bank at any one time outstanding to both Borrowers
shall not exceed the amount of its Commitment.  Each Borrowing under this
subsection (a) shall be in an aggregate principal amount of $3,000,000 or any
larger multiple of $1,000,000 (except that any such Borrowing may be in the
aggregate amount available in accordance with Section 3.02(c)) and shall be
made from the several Banks ratably in proportion to their respective
Commitments.  Within the foregoing limits, either Borrower may borrow under
this subsection (a), or to the extent permitted by Section 2.11, prepay Loans
and reborrow under this subsection (a).



                                       15
<PAGE>   21
         (b)     Extension of Commitments.  The Commitments and the Termination
Date(s) may be extended, in the manner set forth in this subsection (b), on
each successive anniversary of the Effective Date (each such date, an
"Extension Date"), in each case to the date one year from the Termination
Date(s) in effect at such time.  If the Borrowers wish to request an extension
of the Commitments and the Termination Date(s) on any Extension Date, they
shall give notice to that effect to the Agent, not less than 60 days nor more
than 90 days prior to such Extension Date, specifying the Extension Date and
proposed extended Termination Date(s), whereupon the Agent shall promptly
notify each of the Banks of such notice.  Each Bank will use its best efforts
to respond to such request, whether affirmatively or negatively as it may elect
in its sole and absolute discretion, at least 30 days prior to the Extension
Date to the Agent.  A Bank shall be considered to have responded negatively
unless its affirmative response consists of or is accompanied by an executed
counterpart of an Extension Agreement in substantially the form of Exhibit B
hereto, which upon delivery to the Agent shall be irrevocable.  If the Required
Banks do not respond affirmatively to the proposed extension, the Termination
Date(s) then in effect will be retained.  If Banks constituting the Required
Banks respond affirmatively at least 30 days prior to the Extension Date to the
proposed extension (such Banks, "Extending Banks") then the extension shall be
effective and the Commitments of the Extending Banks shall be extended from the
Termination Date(s) then in effect, effective on such Extension Date.  In the
case of any Bank that responded negatively to a proposed extension (a
"Non-Extending Bank"), its Commitment shall expire on, and the Termination Date
with respect to it shall remain as, the Termination Date in effect for it
before giving effect to such extension.  During the 120-day period following any
Extension Date on which the Commitments and the Termination Date(s) in effect
at such time were extended, the Company may notify a Non-Extending Bank of a
bank that is prepared to become an Assignee of its Commitment and its rights
and obligations under this Agreement and its Note, and upon receipt of such
notice such Non-Extending Bank shall promptly effect an assignment to such bank
pursuant to Section 11.06(c).  The Termination Date with respect to such
Assignee shall be the latest date to which the Termination Date(s) of the
Extending Banks were extended on such Extension Date.

         SECTION 2.02. Notice of Committed Borrowing.  The Borrower shall give
the Agent notice (a "Notice of Committed Borrowing") not later than 12:00 Noon
(New York City time) on (x) the date of each Base Rate Borrowing, (y) the
second Domestic Business Day before each CD Borrowing and (z) the

                                      16
<PAGE>   22
third Euro-Dollar Business Day before each Euro-Dollar Borrowing, specifying:

         (a)     the date of such Borrowing, which shall be a Domestic 
    Business Day in the case of a Domestic Borrowing or a Euro-Dollar Business 
    Day in the case of a Euro-Dollar Borrowing,

         (b)      the aggregate amount of such Borrowing,

         (c)      whether the Loans comprising such Borrowing are to be CD
    Loans, Base Rate Loans or Euro-Dollar Loans, and

         (d)     in the case of a Fixed Rate Borrowing, the duration of the
    Interest Period applicable thereto, subject to the provisions of the 
    definition of Interest Period.

         SECTION 2.03. Money Market Borrowings.

         (a)     The Money Market Option.  In addition to Committed Borrowings
pursuant to Section 2.01, a Borrower may, as set forth in this Section, request
the Banks to make offers to make Money Market Loans to such Borrower.  The
Banks may, but shall have no obligation to, make such offers and the Borrower
may, but shall have no obligation to, accept any such offers in the manner set
forth in this Section.

         (b)     Money Market Quote Request.  When a Borrower wishes to request
offers to make Money Market Loans under this Section, it shall transmit to the
Agent by telex or facsimile transmission a Money Market Quote Request
substantially in the form of Exhibit C hereto so as to be received no later
than 12:00 Noon (New York City time) on (x) the fifth Euro-Dollar Business Day
prior to the date of Borrowing proposed therein, in the case of a LIBOR Auction
or (y) the Domestic Business Day next preceding the date of Borrowing proposed
therein, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Company and the Agent shall have mutually agreed and
shall have notified to the Banks not later than the date of the Money Market
Quote Request for the first LIBOR Auction or Absolute Rate Auction for which
such change is to be effective) specifying:

         (i)     the proposed date of Borrowing, which shall be a Euro-Dollar
    Business Day in the case of a LIBOR Auction or a Domestic Business Day in 
    the case of an Absolute Rate Auction,



                                       17
<PAGE>   23
         (ii)    the aggregate amount of such Borrowing, which
    shall be $3,000,000 or a larger multiple of $1,000,000,

         (iii)   the duration of the Interest Period applicable thereto, 
    subject to the provisions of the definition of Interest Period, and

         (iv)    whether the Money Market Quotes requested are to set forth a
    Money Market Margin or a Money Market Absolute Rate.

The Borrower may request offers to make Money Market Loans for more than one
Interest Period in a single Money Market Quote Request.  No Money Market Quote
Request shall be given within five Euro-Dollar Business Days (or such other
number of days as the Company and the Agent may agree) of any other Money
Market Quote Request.

         (c)     Invitation for Money Market Quotes.  Promptly upon receipt of
a Money Market Quote Request, the Agent shall send to the Banks by telex or
facsimile transmission an Invitation for Money Market Quotes substantially in
the form of Exhibit D hereto, which shall constitute an invitation by the
Borrower to each Bank to submit Money Market Quotes offering to make the Money
Market Loans to which such Money Market Quote Request relates in accordance
with this Section.

         (d)     Submission and Contents of Money Market Quotes. (i) Each Bank
may submit a Money Market Quote containing an offer or offers to make Money
Market Loans in response to any Invitation for Money Market Quotes.  Each Money
Market Quote must comply with the requirements of this subsection (d) and must
be submitted to the Agent by telex or facsimile transmission at its offices
specified in or pursuant to Section 11.01 not later than (x) 2:00 P.M. (New
York City time) on the fourth Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) 11:15 A.M. (New York
City time) on the proposed date of Borrowing, in the case of an Absolute Rate
Auction (or, in either case, such other time or date as the Company and the
Agent shall have mutually agreed and shall have notified to the Banks not later
than the date of the Money Market Quote Request for the first LIBOR Auction or
Absolute Rate Auction for which such change is to be effective); provided that
Money Market Quotes submitted by the Agent (or any Affiliate of the Agent) in
the capacity of a Bank may be submitted, and may only be submitted, if the
Agent or such Affiliate notifies the Borrower of the terms of the offer or
offers contained therein not later than (x) one hour prior to the deadline for
the other Banks, in the case of a LIBOR Auction or (y) 15 minutes prior to the
deadline for the other Banks, in the case of an Absolute

                                       18
<PAGE>   24
Rate Auction.  Subject to Articles III and VI, any Money Market Quote so made 
shall be irrevocable except with the written consent of the Agent given on the 
instructions of the Borrower.

         (ii)    Each Money Market Quote shall be in substantially the form of
Exhibit E hereto and shall in any case specify:

         (A)      the proposed date of Borrowing,

         (B)     the principal amount of the Money Market Loan for which
    each such offer is being made, which principal amount (w) may be
    greater than or less than the Commitment of the quoting Bank, (x) must be
    $3,000,000 or a larger multiple of $1,000,000, (y) may not exceed the
    principal amount of Money Market Loans for which offers were requested and
    (z) may be subject to an aggregate limitation as to the principal amount of
    Money Market Loans for which offers being made by such quoting Bank may be
    accepted,

         (C)     in the case of a LIBOR Auction, the margin above or below the
    applicable London Interbank Offered Rate (the "Money Market Margin")
    offered for each such Money Market Loan, expressed as a percentage
    (specified to the nearest 1/10,000th of 1%) to be added to or subtracted
    from such base rate,

         (D)     in the case of an Absolute Rate Auction, the rate of interest
    per annum (specified to the nearest 1/10,000th of 1%) (the "Money
    Market Absolute Rate") offered for each such Money Market Loan, and

         (E)     the identity of the quoting Bank.

         A Money Market Quote may set forth up to five separate offers by the
quoting Bank with respect to each Interest Period specified in the related 
Invitation for Money Market Quotes.

         (iii)   Any Money Market Quote shall be disregarded if it:

         (A)     is not substantially in conformity with Exhibit E hereto or
    does not specify all of the information required by subsection (d)(ii);

         (B)     contains qualifying, conditional or similar language;




                                       19
<PAGE>   25
         (C)     proposes terms other than or in addition to those set forth in
    the applicable Invitation for Money Market Quotes; or

         (D)     arrives after the time set forth in subsection (d)(i).

         (e)     Notice to Borrower. The Agent shall promptly notify the
Borrower of the terms (x) of any Money Market Quote submitted by a Bank that is
in accordance with subsection (d) and (y) of any Money Market Quote that
amends, modifies or is otherwise inconsistent with a previous Money Market
Quote submitted by such Bank with respect to the same Money Market Quote
Request.  Any such subsequent Money Market Quote shall be disregarded by the
Agent unless such subsequent Money Market Quote is submitted solely to correct
a manifest error in such former Money Market Quote.  The Agent's notice to the
Borrower shall specify (A) the aggregate principal amount of Money Market Loans
for which offers have been received for each Interest Period specified in the
related Money Market Quote Request, (B) the respective principal amounts and
Money Market Margins or Money Market Absolute Rates, as the case may be, so
offered and (C) if applicable, limitations on the aggregate principal amount of
Money Market Loans for which offers in any single Money Market Quote may be
accepted.

         (f)     Acceptance and Notice by Borrower.  Not later than 12:00 Noon
(New York City time) on (x) the third Euro-Dollar Business Day prior to the
proposed date of Borrowing, in the case of a LIBOR Auction or (y) the proposed
date of Borrowing, in the case of an Absolute Rate Auction (or, in either case,
such other time or date as the Company and the Agent shall have mutually agreed
and shall have notified to the Banks not later than the date of the Money
Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for
which such change is to be effective) , the Borrower shall notify the Agent of
its acceptance or non-acceptance of the offers so notified to it pursuant to
subsection (e).  In the case of acceptance, such notice (a "Notice of Money
Market Borrowing") shall specify the aggregate principal amount of offers for
each Interest Period that are accepted.  The Borrower may accept any Money
Market Quote in whole or in part; provided that:

         (i)     the aggregate principal amount of each Money Market Borrowing
    may not exceed the applicable amount set forth in the related Money Market
    Quote Request,

         (ii)    the principal amount of each Money Market Borrowing must be
    $3,000,000 or a larger multiple of $1,000,000,

                                      20
<PAGE>   26
         (iii)   acceptance of offers may only be made on the basis of 
    ascending Money Market Margins or Money Market Absolute Rates, as the case 
    may be, and

         (iv)    the Borrower may not accept any offer that is described in
    subsection (d)(iii) or that otherwise fails to comply with the 
    requirements of this Agreement.

         (g)     Allocation by Agent.  If offers are made by two or more Banks
with the same Money Market Margins or Money Market Absolute Rates, as the case
may be, for a greater aggregate principal amount than the amount in respect of
which such offers are accepted for the related Interest Period, the principal
amount of Money Market Loans in respect of which such offers are accepted shall
be allocated by the Agent among such Banks as nearly as possible (in multiples
of $1,000,000, as the Agent may deem appropriate) in proportion to the
aggregate principal amounts of such offers.  Determinations by the Agent of the
amounts of Money Market Loans shall be conclusive in the absence of manifest
error.

         SECTION 2.04. Notice to Banks; Funding of Loans.

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

         (b)     Not later than 2:00 P.M. (New York City time) on the date of
each Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in
Federal or other funds immediately available in New York City, to the Agent at
its address referred to in Section 11.01. Unless the Agent determines that any
applicable condition specified in Article III has not been satisfied, the Agent
will make the funds so received from the Banks available to the Borrower at the
Agent's aforesaid address.

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


                                       21
<PAGE>   27
         (d)     Unless the Agent shall have received notice from a Bank prior
to the date of any Borrowing that such Bank will not make available to the
Agent such Bank's share of such Borrowing, the Agent may assume that such Bank
has made such share available to the Agent on the date of such Borrowing in
accordance with subsections (b) and (c) of this Section 2.04 and the Agent may,
in reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Bank shall not have so
made such share available to the Agent, such Bank and the Borrower severally
agree to repay to the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Agent, at
(i) in the case of the Borrower, a rate per annum equal to the higher of the
Federal Funds Rate and the interest rate applicable thereto pursuant to Section
2.07 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank
shall repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

         SECTION 2.05. Notes. (a) The Loans of each Bank to each Borrower shall
be evidenced by a single Note of such Borrower payable to the order of such
Bank for the account of its Applicable Lending Office in an amount equal to the
aggregate unpaid principal amount of such Bank's Loans to such Borrower.

         (b)     Each Bank may, by notice to either Borrower and the Agent,
request that its Loans of a particular type to such Borrower be evidenced by a
separate Note of such Borrower in an amount equal to the aggregate unpaid
principal amount of such Loans.  Each such Note shall be in substantially the
form of Exhibit A hereto with appropriate modifications to reflect the fact
that it evidences solely Loans of the relevant type.  Each reference in this
Agreement to a "Note" or the "Notes" of such Bank shall be deemed to refer to
and include any or all of such Notes, as the context may require.

         (c)     Upon receipt of each Bank's Note pursuant to Section 3.01(a),
the Agent shall forward such Note to such Bank.  Each Bank shall record the
date, amount, type and maturity of each Loan made by it to each Borrower and
the date and amount of each payment of principal made by the Borrower with
respect thereto, and may, if such Bank so elects in connection with any
transfer or enforcement of its Note of either Borrower, endorse on the schedule
forming a part thereof appropriate notations to evidence the foregoing
information with respect to each such Loan to such Borrower then outstanding;
provided that the failure of any Bank to

                                       22
<PAGE>   28
make any such recordation or endorsement shall not affect the obligations of
either Borrower hereunder or under the Notes.  Each Bank is hereby irrevocably
authorized by each Borrower so to endorse its Notes and to attach to and make a
part of any Note a continuation of any such schedule as and when required.

         SECTION 2.06.  Maturity of Loans.  Each Loan included in any Borrowing
shall mature, and the principal amount thereof shall be due and payable, on the
last day of the Interest Period applicable to such Borrowing.

         SECTION 2.07. Interest Rates. (a) Each Base Rate 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
Base Rate for such day.  Such interest shall be payable for each Interest
Period on the last day thereof.  Any overdue principal of or interest on any
Base Rate Loan shall bear interest, payable on demand, for each day until paid
at a rate per annum equal to the sum of 2% plus the rate otherwise applicable
to Base Rate Loans for such day.

         (b)     Each CD Loan shall bear interest on the outstanding principal
amount thereof, for each day during the Interest Period applicable thereto, at
a rate per annum equal to the sum of the CD Margin for such day plus the
Adjusted CD Rate applicable to such Interest Period; provided that if any CD
Loan or any portion thereof shall, as a result of clause (2)(b) of the
definition of Interest Period, have an Interest Period of less than 30 days,
such portion shall bear interest during such Interest Period at the rate
applicable to Base Rate Loans during such period.  Such interest shall be
payable for each Interest Period on the last day thereof and, if such Interest
Period is longer than 90 days, at intervals of 90 days after the first day
thereof. Any overdue principal of or interest on any CD Loan shall bear
interest, payable on demand, for each day until paid at a rate per annum equal
to the sum of 2% plus the higher of (i) the sum of the CD Margin for such day
plus the Adjusted CD Rate applicable to the Interest Period for such Loan and
(ii) the rate applicable to Base Rate Loans for such day.

         "CD Margin" means a rate per annum determined in accordance with the
Pricing Schedule.

         The "Adjusted CD Rate" applicable to any Interest Period means a rate
per annum determined pursuant to the following formula:




                                      23
<PAGE>   29
                                [  CDBR        ]*
                       ACDR  =  [  ----------  ]    + AR
                                [  1.00 - DRP  ]

                       ACDR  =  Adjusted CD Rate
                       CDBR  =  CD Base Rate

                        DRP  =  Domestic Reserve Percentage
                         AR  =  Assessment Rate

         ----------
         * The amount in brackets being rounded upward, if
           necessary, to the next higher 1/100 of 1%

         The "CD Base Rate" applicable to any Interest Period is the rate of
interest determined by the Agent to be the average (rounded upward, if
necessary, to the next higher 1/100 of 1%) of the prevailing rates per annum
bid at 10:00 A.M. (New York City time) (or as soon thereafter as practicable)
on the first day of such Interest Period by two or more New York certificate of
deposit dealers of recognized standing for the purchase at face value from each
CD Reference Bank of its certificates of deposit in an amount comparable to the
principal amount of the CD Loan of such CD Reference Bank to which such
Interest Period applies and having a maturity comparable to such Interest
Period.

         "Domestic Reserve Percentage" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement (including without limitation any
basic, supplemental or emergency reserves) for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of new non-personal time deposits in dollars in New York City having a
maturity comparable to the related Interest Period and in an amount of $100,000
or more. The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Domestic Reserve Percentage.

         "Assessment Rate" means for any day the annual assessment rate in
effect on such day which is payable by a member of the Bank Insurance Fund
classified as adequately capitalized and within supervisory subgroup "A" (or a
comparable successor assessment risk classification) within the meaning of 12
C.F.R. Sec. 327.3(d) (or any successor provision) to the Federal Deposit
Insurance Corporation (or any successor) for such Corporation's (or such
successor's) insuring time deposits at offices of such institution in the
United States.  The Adjusted CD Rate shall be adjusted


                                       24
<PAGE>   30
automatically on and as of the effective date of any change in the Assessment
Rate.

         (c)     Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for
such day plus the Adjusted London Interbank offered Rate applicable to such
Interest Period.  Such interest shall be payable for each Interest Period on
the last day thereof and, if such Interest Period is longer than three months,
at intervals of three months after the first day thereof.

         "Euro-Dollar Margin" means a rate per annum determined in accordance
with the Pricing Schedule.

         The "Adjusted London Interbank Offered Rate" applicable to any
Interest Period means a rate per annum equal to the quotient obtained (rounded
upward, if necessary, to the next higher 1/100 of 1%) by dividing (i) the
applicable London Interbank Offered Rate by (ii) 1.00 minus the Euro-Dollar
Reserve Percentage.

         The "London Interbank Offered Rate" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
each of the Euro-Dollar Reference Banks in the London interbank market, as
determined by each Euro-Dollar Reference Bank at approximately 11:00 A.M.
(London time) two Euro-Dollar Business Days before the first day of such
Interest Period in an amount approximately equal to the principal amount of the
Euro-Dollar Loan of such Euro-Dollar Reference Bank to which such Interest
Period is to apply and for a period of time comparable to such Interest Period.

         "Euro-Dollar Reserve Percentage" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or
other assets which includes loans by a non-United States office of any Bank to
United States residents).  The Adjusted London Interbank Offered Rate shall be
adjusted automatically on and as of the effective date of any change in the
Euro-Dollar Reserve Percentage.

         (d)     Any overdue principal of or interest on any Euro-Dollar Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the higher of (i) the sum of 2% plus the Euro-Dollar Margin for
such day plus the Adjusted London Interbank Offered Rate applicable to the
Interest Period for such Loan and (ii) the sum of 2% plus the Euro-Dollar
Margin for such day plus the quotient obtained (rounded upward, if necessary,
to the next higher 1/100 of 1%) by dividing (x) the average (rounded upward, if
necessary, to the next higher 1/16 of 1%) of the respective rates per annum at
which one day (or, if such amount due remains unpaid more than three
Euro-Dollar Business Days, then for such other period of time not longer than
six months as the Agent may select) deposits in dollars in an amount
approximately equal to such overdue payment due to each of the Euro-Dollar
Reference Banks are offered to such Euro-Dollar Reference Bank in the London
interbank market for the applicable period determined as provided above by (y)
1.00 minus the Euro-Dollar Reserve Percentage (or, if the circumstances
described in clause (a) or (b) of Section 8.01 shall exist, at a rate per annum
equal to the sum of 2% plus the rate applicable to Base Rate Loans for such
day).

         (e)     Subject to Section 8.01(a), each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the sum of the London
Interbank offered Rate for such Interest Period (determined in accordance with
Section 2.07(c) as if the related Money Market LIBOR Borrowing were a Committed
Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the
Bank making such Loan in accordance with Section 2.03. Each Money Market
Absolute Rate Loan shall bear interest on the outstanding principal amount
thereof, for the Interest Period applicable thereto, at a rate per annum equal
to the Money Market Absolute Rate quoted by the Bank making such Loan in
accordance with Section 2.03. Such interest shall be payable for each Interest
Period on the last day thereof and, if such Interest Period is longer than
three months, at intervals of three months after the first day thereof.  Any
overdue principal of or interest on any Money Market Loan shall bear interest,
payable on demand, for each day until paid at a rate per annum equal to the sum
of 2% plus the Base Rate for such day.

         (f)      The Agent shall determine each interest rate applicable to   
the Loans hereunder.  The Agent shall give prompt notice to the Borrower and
the participating Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.


                                       26
<PAGE>   32
         (g)     Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section.  If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available
on a timely basis, the provisions of Section 8.01 shall apply.  So long as
quotations are available from all four of the Reference Banks, the highest of
such quotations shall be disregarded for purposes of rate determinations
hereunder.

         SECTION 2.08. Fees.

         (a)     Facility Fee.  The Company shall pay to the Agent for the
account of each Bank a facility fee at the Facility Fee Rate (determined daily
in accordance with the Pricing Schedule).  Such facility fee shall accrue for
the account of each Bank (i) from and including the date hereof to but
excluding its Termination Date or earlier date of termination of its Commitment
in its entirety, on the daily amount of its Commitment (whether used or unused)
and (ii) from and including its Termination Date or such earlier date of
termination to but excluding the date its Loans shall be repaid in their
entirety, on the daily aggregate outstanding principal amount of its Loans.

         (b)     Payments.  Accrued fees under this Section shall be payable
quarterly on each March 31, June 30, September 30 and December 31 and upon the
date of termination of the Commitments in their entirety (or, with respect to a
Non-Extending Bank, the Termination Date applicable to it) and, if later, the
date the Loans of any Bank shall be repaid in their entirety.

         SECTION 2.09. Optional Termination or Reduction of Commitments.  The
Company may, upon at least three Domestic Business Days' notice to the Agent,
(i) terminate the Commitments at any time, if no Loans are outstanding at such
time or (ii) ratably reduce from time to time by an aggregate amount of
$1,000,000 or any larger multiple thereof, the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans.

         SECTION 2.10. Mandatory Termination of Commitments. The Commitment of
each Bank shall terminate on the Termination Date for such Bank, and any Loans
of such Bank then outstanding (together with accrued interest thereon) shall be
due and payable on such date.

         SECTION 2.11. Optional Prepayments. (a) Subject in the case of any
Fixed Rate Borrowing to Section 2.13, the Borrower may, upon at least one
Domestic Business Day's

                                       27
<PAGE>   33
notice to the Agent, prepay any Domestic Borrowing (or any Money Market
Borrowing bearing interest at the Base Rate pursuant to Section 8.01(a)) or
upon at least three EuroDollar Business Days' notice to the Agent, prepay any
EuroDollar Borrowing, in each case in whole at any time, or from time to time
in part in amounts aggregating $3,000,000 or any larger multiple of $l,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 ratably the Loans of the several Banks included in such
Borrowing.

         (b)     Except as provided in Section 2.11(a), neither Borrower may
prepay all or any portion of the principal amount of any Money Market Loan
prior to the maturity thereof.

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

         SECTION 2,12.  General Provisions as to Payments.

        (a)     The Borrowers shall make each payment of principal of, and
interest on, the Loans and of fees hereunder, not later than 12:00 Noon (New
York City time) on the date when due, in Federal or other funds immediately
available in New York City, to the Agent at its address referred to in Section
11.01. The Agent will promptly distribute to each Bank its ratable share of
each such payment received by the Agent for the account of the Banks.  Whenever
any payment of principal of, or interest on, the Domestic Loans or of fees
shall be due on a day which is not a Domestic Business Day, the date for
payment thereof shall be extended to the next succeeding Domestic Business Day. 
Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in another calendar month, in
which case the date for payment thereof shall be the next preceding Euro-Dollar
Business Day.  Whenever any payment of principal of, or interest on, the Money
Market Loans shall be due on a day which is not a Euro-Dollar Business Day,
the date for payment thereof shall be extended to the next succeeding
Euro-Dollar Business Day. If the date for any payment of principal is extended
by operation of law or otherwise, interest thereon shall be payable for such
extended time.

         (b)     Unless the Agent shall have received notice from either
Borrower prior to the date on which any payment is due from such Borrower to
the Banks hereunder that such

                                      28
<PAGE>   34
Borrower will not make such payment in full, the Agent may assume that such 
Borrower has made such payment in full to the Agent on such date and the Agent 
may, in reliance upon such assumption, cause to be distributed to each Bank on 
such due date an amount equal to the amount then due such Bank.  If and to the 
extent that such Borrower shall not have so made such payment, each Bank shall 
repay to the Agent forthwith on demand such amount distributed to such Bank 
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Agent, at the Federal Funds Rate.

         SECTION 2.13, Funding Losses.  If either Borrower makes any payment of
principal with respect to any Fixed Rate Loan (pursuant to Article VI or VIII
or otherwise) on any day other than the last day of the Interest Period
applicable thereto, or the last day of an applicable period fixed pursuant to
Section 2.07(d), or if either Borrower fails to borrow or prepay any Fixed Rate
Loans after notice has been given to any Bank in accordance with Section 2. 04
(a) or 2.11 (c), the Company shall reimburse each Bank within 15 days after
demand for any resulting loss or expense incurred by it (or by an existing or
prospective Participant in the related Loan), including (without limitation)
any loss incurred in obtaining, liquidating or employing deposits from third
parties, but excluding loss of margin for the period after any such payment or
failure to borrow or prepay, provided that such Bank shall have delivered to
the Company a certificate as to the amount of such loss or expense, which
certificate shall be conclusive in the absence of manifest error.

         SECTION 2.14. Computation of Interest and Fees.  Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
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).

    existence of each Borrower, the corporate authority for and the validity of
    this Agreement and the Notes of such Borrower, and any other matters 
    relevant hereto, all in form and substance satisfactory to the Agent.

The Agent shall promptly notify the Borrowers and the Banks of the Closing
Date, and such notice shall be conclusive and binding on all parties hereto.

         SECTION 3.02. Borrowings.  The obligation of any Bank to make a Loan
on the occasion of any Borrowing is subject to the satisfaction of the
following conditions:

         (a)      the fact that the Closing Date shall have occurred on or 
    prior to April 15, 1994;

    Default shall have occurred and be continuing; and

         (e)     the fact that the representations and warranties of the

<PAGE>   36
         been disclosed in writing by the Company to the Banks) shall be true
         on and as of the date of such Borrowing.

                 Each Borrowing hereunder shall be deemed to be a
representation and warranty by the Borrower on the date of such Borrowing as to
the facts specified in clauses (c), (d) and (e) of this Section.


                                   ARTICLE IV

         The Company represents and warrants that:

corporation duly incorporated, validly existing and in good standing under the
laws of the state of its incorporation, and has all corporate powers and all
material governmental licenses, authorizations, consents and approvals required
to carry on its business as now conducted.

         SECTION 4.02, Corporate and Governmental Authorization; No
Contravention.  The execution, delivery and performance by the Company of this
Agreement and the Notes are within the Company's corporate powers, have been
duly authorized by all necessary corporate action, require no action by or in
respect of, or filing with, any governmental body, agency or official and do
not contravene, or constitute a default under, any provision of applicable law
or regulation or of the certificate of incorporation or by-laws of the Company
or of any agreement, judgment, injunction, order, decree or other instrument
binding upon the Company or any of its Consolidated Subsidiaries or result in
the creation or imposition of any Lien on any asset of the Company or any of
its Consolidated Subsidiaries.

         SECTION 4.03. Binding Effect.  This Agreement constitutes a valid and
binding agreement of the Company and its Notes, when executed and delivered in
accordance with this Agreement, will constitute a valid and binding obligation
of the Company, in each case enforceable in accordance with its terms,

         SECTION 4.04. Financial Information.

         (a)     The consolidated balance sheet of the Company and its
Consolidated Subsidiaries as of December 31, 1992 and the related consolidated
statements of income, retained earnings and cash flows for the fiscal year then
ended,

                                       31
<PAGE>   37
reported on by Deloitte & Touche and set forth in the Company's 1992 Form 10-K,
a copy of which has been delivered to each of the Banks, fairly present, in
conformity with generally accepted accounting principles, the consolidated
financial position of the Company and its Consolidated Subsidiaries as of such
date and their consolidated results of operations and cash flows for such
fiscal year.

         (b)     The unaudited consolidated balance sheet of the Company and
its Consolidated Subsidiaries as of September 30, 1993 and the related
unaudited consolidated statements of income and cash flows for the nine months
then ended, set forth in the Company's Latest Form 10-Q, a copy of which has
been delivered to each of the Banks, fairly present, in conformity with
generally accepted accounting principles applied on a basis consistent with the
financial statements referred to in subsection (a) of this Section, the
consolidated financial position of the Company and its Consolidated
Subsidiaries as of such date and their consolidated results of operations and
cash flows for such nine month period (subject to year-end audit adjustments).

         (c)     Since September 30, 1993, there has been no material adverse
change in the business, financial position, results of operations or prospects
of the Company and its Consolidated Subsidiaries, considered as a whole.

         SECTION 4.05. Litigation.  There is no action, suit or proceeding
pending against, or to the knowledge of the Company threatened against or
affecting, the Company or any of its Consolidated Subsidiaries before any court
or arbitrator or any governmental body, agency or official in which there is a
reasonable possibility of an adverse decision which could materially adversely
affect the business, consolidated financial position or consolidated results of
operations of the Company and its Consolidated Subsidiaries, considered as a
whole, or which in any manner draws into question the validity of this
Agreement or the Notes.

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

                                       32
<PAGE>   38
Lien or the posting of a bond or other security under ERISA or the Internal
Revenue Code or (iii) incurred any liability under Title IV of ERISA other than
a liability to the PBGC for premiums under Section 4007 of ERISA.

         SECTION 4.07. Environmental Matters.  In the ordinary course of its
business, the company conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Company and its
Consolidated Subsidiaries, in the course of which it identifies and evaluates
associated liabilities and costs (including, without limitation, 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 Substances, and any actual or potential
liabilities to third parties, including employees, and any related costs and
expenses).  On the basis of this review, the Company has reasonably concluded
that such associated liabilities and costs, including the costs of compliance
with Environmental Laws, are unlikely to have a material adverse effect on the
business, financial condition, results of operations or prospects of the
Company and its Consolidated Subsidiaries, considered as a whole.

         SECTION 4.08.  Taxes.  The Company and its Consolidated Subsidiaries
have filed all United States Federal income tax returns and all other material
tax returns which are required to be filed by them and have paid all taxes due
pursuant to such returns or pursuant to any assessment received by the Company
or any Consolidated Subsidiary.  The charges, accruals and reserves an the
books of the Company and its Consolidated Subsidiaries in respect of taxes or
other governmental charges are, in the opinion of the Company, adequate.

         SECTION 4,09.  Consolidated Subsidiaries.  Each of the Company's
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.

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

    in excess in value, in the aggregate for all such sales, transfers,
    conveyances, leases or other disposals per fiscal year of the Company and
    Consolidated Subsidiaries of the Sale Limit (as hereinafter defined)
    (provided that any primary or secondary sale of equity securities of a

    Subsidiary shall be deemed to be a sale of all the assets of such
    Consolidated Subsidiary); or

          (c)    sell or assign, with or without recourse, any accounts
    receivable or chattel paper, in excess for the aggregate face amount of

                   (y)     any Consolidated Subsidiary may consolidate with 
         any other Consolidated Subsidiary so long as the resulting Person is a 
         Consolidated Subsidiary; and

                   (z)     any Consolidated Subsidiary may sell, transfer, 
         convey, lease or assign any or all of its assets to the Company or 
         other Consolidated Subsidiary; provided, in each of the cases 
         described in preceding clauses (x), (y) and (z), that immediately 
         thereafter and after giving effect thereto, no Default shall have 
         occurred and be continuing.

         For purposes of this Section 5.13 only, the "Sale Limit" shall mean an
annual amount equalling 25% of Consolidated Tangible Net Worth determined as of

    holder of such Indebtedness or any Person acting on such holder's behalf to
    accelerate the maturity thereof;

         (h)     the Company or any Consolidated Subsidiary shall commence a
    voluntary case or other proceeding seeking liquidation, reorganization
    or other relief with respect to itself or its debts under any bankruptcy,
    insolvency or other similar law now or hereafter in effect or seeking the
    appointment of a trustee, receiver, liquidator, custodian or other similar
    official of it or any substantial part of its property, or shall consent to
    any such relief or to the appointment of or taking possession by any such
    official in an involuntary case or other proceeding commenced against it,

    fail generally to pay its debts as they become due, or shall take any
    corporate action to authorize any of the foregoing;

                                       41
<PAGE>   47
         (i)     an involuntary case or other proceeding shall be commenced

    terminate a Material Plan shall be filed under Title IV of ERISA by any
    member of the ERISA Group, any plan administrator or any combination of the
    foregoing; or the PBGC shall institute proceedings under Title IV of ERISA
    to terminate, to impose liability (other than for premiums under Section
    4007 of ERISA) in respect of, or to cause a trustee to be appointed to
    administer any Material Plan; or a condition shall exist by reason of which
    the PBGC would be entitled to obtain a decree adjudicating that any
    Material Plan must be terminated; or there shall occur a complete or
    partial withdrawal from, or a default, within the meaning of Section
    4219(c)(5) of ERISA, with respect to, one or more Multiemployer Plans
    which could cause one or more members of the ERISA Group to incur a current
    payment obligation in excess of $10,000,000;

         (k)     judgments or orders for the payment of money in excess of
    $10,000,000 in the aggregate shall be rendered against the Company or any
    Consolidated Subsidiary and such judgments or orders shall continue 
    unsatisfied and unstayed for a period of 30 days; or

         (l)     any person or group of persons (within the meaning of Section
    13 or 14 of the Securities Exchange Act of 1934, as amended) shall have

                                      42
<PAGE>   48
    period shall cease to constitute a majority of the board of directors of 
    the Company;

then, and in every such event, the Agent shall (i) if requested by Banks having
more than 50% in aggregate amount of the Commitments, by notice to the Company
terminate the Commitments and they shall thereupon terminate, and (ii) if
requested by Banks holding Notes evidencing more than 50% in aggregate
principal amount of the Loans, by notice to the Borrowers declare the Notes
(together with accrued interest thereon) to be, and the Notes shall thereupon
become, immediately due and payable without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by each Borrower;
provided that in the case of any of the Events of Default specified in clause

                                   THE AGENT

         SECTION 7.01. Appointment and Authorization.  Each Bank irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement and the Notes as are delegated
to the Agent by the terms hereof or thereof, together with all such powers as
are reasonably incidental thereto.

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

         SECTION 7.03. Action by Agent.  The obligations of the Agent hereunder
are only those expressly set forth

                                       43
<PAGE>   49
herein.  Without limiting the generality of the foregoing, the Agent shall not
be required to take any action with respect to any Default, except as expressly
provided in Article VI.

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

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

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

         SECTION 7.07. Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made 

                                      44

<PAGE>   50
its own credit analysis and decision to enter into this Agreement.  Each Bank 
also acknowledges that it will, independently and without reliance upon the 
Agent or any other Bank, and based on such documents and information as it 
shall deem appropriate at the time, continue to make its own credit decisions 
in taking or not taking any action under this Agreement.

         SECTION 7.08. Successor Agent.  The Agent may resign at any time by
giving notice thereof to the Banks and the Company.  Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent.  If no
successor Agent shall have been so appointed by the Required Banks, and shall
have accepted such appointment, within 30 days after the retiring Agent gives
notice of resignation, then the retiring Agent may, on behalf of the Banks,
appoint a successor Agent, which shall be a commercial bank organized or
licensed under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $50,000,000.  Upon the
acceptance of its appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder.  After any retiring
Agent's resignation hereunder as Agent, the provisions of this Article shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent.

         SECTION 7.09. Agent's Fee.  The Company shall pay to the Agent for its
own account fees in the amounts and at the times previously agreed upon between
the Company and the Agent.


                                  ARTICLE VIII

                            CHANGE IN CIRCUMSTANCES

         SECTION 8.01. Basis for Determining Interest Rate Inadequate or
Unfair.  If on or prior to the first day of any Interest Period for any Fixed
Rate Borrowing:

         (a)     the Agent is advised by the Reference Banks that deposits in
    dollars (in the applicable amounts) are not being offered to the Reference
    Banks in the relevant market for such Interest Period, or

         (b)     in the case of a Committed Borrowing, Banks having 50% or more
    of the aggregate amount of the Commitments advise the Agent that the 
    Adjusted CD Rate

                                      45
<PAGE>   51
    or the Adjusted London Interbank Offered Rate, as the case may be, as
    determined by the Agent will not adequately and fairly reflect the cost to
    such Banks of funding their CD Loans or Euro-Dollar Loans, as the case may
    be, for such Interest Period,

the Agent shall forthwith give notice thereof to the Company and the Banks,
whereupon until the Agent notifies the Company that the circumstances giving
rise to such suspension no longer exist, the obligations of the Banks to make
CD Loans or Euro-Dollar Loans, as the case may be, shall be suspended.  Unless
the Borrower notifies the Agent at least two Domestic Business Days before the
date of any Fixed Rate Borrowing for which a Notice of Borrowing has previously
been given that it elects not to borrow on such date, (i) if such Fixed Rate
Borrowing is a Committed Borrowing, such Borrowing shall instead be made as a
Base Rate Borrowing and (ii) if such Fixed Rate Borrowing is a Money Market
LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing shall
bear interest for each day from and including the first day to but excluding
the last day of the Interest Period applicable thereto at the Base Rate for
such day.

         SECTION 8.02. Illegality.  If, on or after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Euro-Dollar Lending Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall make it unlawful or impossible for any
Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its
Euro-Dollar Loans to either Borrower and such Bank shall so notify the Agent,
the Agent shall forthwith give notice thereof to the other Banks and the
Borrower, whereupon until such Bank notifies the Borrower and the Agent that
the circumstances giving rise to such suspension no longer exist, the
obligation of such Bank to make Euro-Dollar Loans to such Borrower shall be
suspended.  Before giving any notice to the Agent pursuant to this Section,
such Bank shall designate a different Euro-Dollar Lending Office if such
designation will avoid the need for giving such notice and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank.  If such Bank
shall determine that it may not lawfully continue to maintain and fund any of
its outstanding Euro-Dollar Loans to maturity and shall so specify in such
notice, the Borrower shall immediately prepay in full the then outstanding
principal amount of each such Euro-Dollar Loan, together with accrued interest

                                      46
<PAGE>   52
thereon. Concurrently with prepaying each such Euro-Dollar Loan, the Borrower 
shall borrow a Base Rate Loan in an equal principal amount from such Bank (on 
which interest and principal shall be payable contemporaneously with the 
related Euro-Dollar Loans of the other Banks), and such Bank shall make such a 
Base Rate Loan.

         SECTION 8.03. Increased Cost and Reduced Return.  (a) If on or after
(x) the date hereof, in the case of any Committed Loan or any obligation to
make Committed Loans or (y) the date of the related Money Market Quote, in the
case of any Money Market Loan, the adoption of any applicable law, rule or
regulation, or any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall impose, modify
or deem applicable any reserve (including, without limitation, any such
requirement imposed by the Board of Governors of the Federal Reserve System,
but excluding (i) with respect to any CD Loan any such requirement included in
an applicable Domestic Reserve Percentage and (ii) with respect to any
Euro-Dollar Loan any such requirement included in an applicable Euro-Dollar
Reserve Percentage), special deposit, insurance assessment (excluding, with
respect to any CD Loan, any such requirement reflected in an applicable
Assessment Rate) or similar requirement against assets of, deposits with or for
the account of, or credit extended by, any Bank (or its Applicable Lending
Office) or shall impose on any Bank (or its Applicable Lending Office) or on
the United States market for certificates of deposit or the London interbank
market any other condition affecting its Fixed Rate Loans, its Note or its
obligation to make Fixed Rate Loans and the result of any of the foregoing is
to increase the cost to such Bank (or its Applicable Lending Office) of making
or maintaining any Fixed Rate Loan, or to reduce the amount of any sum received
or receivable by such Bank (or its Applicable Lending Office) under this
Agreement or under its Note with respect thereto, by an amount deemed by such
Bank to be material, then, within 15 days after demand by such Bank (with a
copy to the Agent), the Company shall pay to such Bank such additional amount
or amounts as will compensate such Bank for such increased cost or reduction.

         (b)     If any Bank shall have determined that, after the date hereof,
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental

                                      47


<PAGE>   53
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 Bank (or its Parent) as a consequence of such Bank's
obligations hereunder to a level below that which such Bank (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Bank to be material, then from time to time, within 15 days
after demand by such Bank (with a copy to the Agent), the company shall pay to
such Bank such additional amount or amounts as will compensate such Bank (or
its Parent) for such reduction.

         (c)     Each Bank will promptly notify the Company and the Agent of
any event of which it has knowledge, occurring after the date hereof, which
will entitle such Bank to compensation pursuant to this Section and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank.  A
certificate of any Bank claiming compensation under this Section and setting
forth the additional amount or amounts to be paid to it hereunder shall be
conclusive in the absence of manifest error.  In determining such amount, such
Bank may use any reasonable averaging and attribution methods.

         SECTION 8.04. Taxes.  (a) For purposes of this Section 8.04, the
following terms have the following meanings:

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


                                      48
<PAGE>   54
         "Other Taxes" means any present or future stamp or documentary taxes
and any other excise or property taxes, or similar charges or levies, which
arise from any payment made pursuant to this Agreement or under any Note or
from the execution or delivery of, or otherwise with respect to, this Agreement
or any Note.

         (b)     Any and all payments by either Borrower to or for the account
of any Bank or the Agent hereunder or under any Note 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 8.04) such Bank or the Agent (as the case may be) receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) 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 Section 11.01, the original
or a certified copy of a receipt evidencing payment thereof,

         (c)     The Company agrees to indemnify each Bank and the Agent for
the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable
under this Section 8.04) paid by such Bank or the Agent (as the case may be)
and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto.  This indemnification shall be paid within
15 days after such Bank or the Agent (as the case may be) makes demand
therefor.

         (d)     Each Bank organized under the laws of a jurisdiction outside
the United States, on or prior to the date of its execution and delivery of
this Agreement in the case of each Bank listed on the signature pages hereof
and on or prior to the date on which it becomes a Bank in the case of each
other Bank, and from time to time thereafter if requested in writing by the
Borrower (but only so long as such Bank remains lawfully able to do so), shall
provide each Borrower with Internal Revenue Service form 1001 or 4224, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Bank is entitled to benefits under an income tax treaty to
which the United States is a party which exempts the Bank from United States
withholding tax or reduces the rate of withholding tax on payments of interest
for the account of such Bank or certifying that the income receivable pursuant
to this

                                      49
<PAGE>   55
Agreement is effectively connected with the conduct of a trade or business in
the United States.

         (e)     For any period with respect to which a Bank has failed to
provide either Borrower with the appropriate form pursuant to Section 8.04(d)
(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 Bank shall not be entitled to indemnification under Section
8.04(b) or (c) with respect to Taxes imposed by the United States on payments
by such Borrower; provided that if a Bank, which is otherwise exempt from or
subject to a reduced rate of withholding tax, becomes subject to Taxes because
of its failure to deliver a form required hereunder, such Borrower shall take
such steps as such Bank shall reasonably request to assist such Bank to recover
such Taxes,

         (f)     If either Borrower is required to pay additional amounts to or
for the account of any Bank pursuant to this Section 8.04, then such Bank will
change the jurisdiction of its Applicable Lending office if, in the judgment of
such Bank, such change (i) will eliminate or reduce any such additional payment
which may thereafter accrue and (ii) is not otherwise disadvantageous to such
Bank.

         SECTION 8.05.  Base Rate Loans Substituted for Affected Fixed Rate
Loans.  If (i) the obligation of any Bank to make Euro-Dollar Loans to either
Borrower has been suspended pursuant to Section 8,02 or (ii) any Bank has
demanded compensation under Section 8.03 or 8.04 with respect to its CD Loans
or Euro-Dollar Loans and the Borrower shall, by at least five Euro-Dollar
Business Days' prior notice to such Bank through the Agent, have elected that
the provisions of this Section shall apply to such Bank, then, unless and until
such Bank notifies the Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist:

         (a)     all Loans to such Borrower which would otherwise be made by
    such Bank as CD Loans or Euro-Dollar Loans, as the case may be, shall
    be made instead as Base Rate Loans (on which interest and principal shall
    be payable contemporaneously with the related Fixed Rate Loans of the other
    Banks), and

         (b)     after each of its CD Loans or Euro-Dollar Loans, as the case
    may be, to such Borrower has been repaid, all payments of principal
    which would otherwise be applied to repay such Fixed Rate Loans shall be
    applied to repay its Base Rate Loans instead.


                                      50
<PAGE>   56
         SECTION 8.06. Substitution of Bank.  If (i) the obligation of any Bank
to make Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii)
any Bank has demanded compensation under Section 8.03 or 8.04, the Borrowers
shall have the right, with the assistance of the Agent, to seek a mutually
satisfactory substitute bank or banks (which may be one or more of the Banks)
to purchase the Note and assume the Commitment of such Bank.

the obligations of each Borrower hereunder shall be unconditional and absolute
and, without limiting the generality of the foregoing, shall not be released,

    any Bank 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;

         (vi)    any invalidity or unenforceability relating to or against the
    other Borrower for any reason of this Agreement or any Note, 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

                                      52
<PAGE>   58
         (vii)   any other act or omission to act or delay of any kind by the
    other Borrower, the Agent, any Bank 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 
    hereunder.

         SECTION 10.03. 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
Company and MK-Ohio 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.

         SECTION 10.04.  Waiver by the Borrowers.  Each Borrower irrevocably

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 Required
Banks.

         SECTION 10.07. Limit of Liability.  The obligations of MK-Ohio under
this Article X shall be limited to an aggregate amount equal to the largest

                                   ARTICLE XI

                                 MISCELLANEOUS


         SECTION 11.01. Notices.  All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission or similar writing) and shall be given to such
party: (X) in the case of either Borrower or the Agent, at its address,
facsimile number or telex number set forth on the signature pages hereof, (y)
in the case of any Bank, at its address, facsimile number or telex number set
forth in its Administrative Questionnaire or (z) in the case of any party, such
other address, facsimile number or telex number as such party may hereafter
specify for the purpose by notice to the Agent and the Company.  Each such
notice, request or other communication shall be effective (i) if given by
telex, when such telex is transmitted to the telex number specified in this
Section and the appropriate answerback is received, (ii) if given by facsimile
transmission, when transmitted to the facsimile number specified in this
Section and confirmation of receipt is received, (iii) if given by mail, 72
hours after such communication is deposited in the mails with first class
postage prepaid, addressed as aforesaid or (iv) if given by any other means,
when delivered at the address specified in this Section; provided that notices
to the Agent under Article II or Article VIII shall not be effective until
received.

         SECTION 11.02.  No Waivers.  No failure or delay by the Agent or any
Bank in exercising any right, power or privilege hereunder or under any Note
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.

         SECTION 11.03. Expenses; Indemnification.  (a) The Company shall pay
(i) all reasonable out-of-pocket expenses of the Agent, including reasonable
fees and disbursements of special counsel for the Agent, 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
and (ii) if an Event of Default occurs, all reasonable out-of-pocket expenses
incurred by the Agent and each Bank, including the

                                      54
<PAGE>   60
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.

         (b)     The Company agrees to indemnify the Agent and each Bank, their
respective Affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel (including allocated costs of internal counsel), 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 relating to or arising out of
this Agreement or any actual or proposed use of proceeds of Loans hereunder;
provided that no Indemnitee shall have the right to be indemnified hereunder
(i) for such Indemnitee's own gross negligence or willful misconduct or (ii) in
the case of any Bank, 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.

         SECTION 11.04. Sharing of Set-Offs.  Each Bank 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
with respect to any Note held by it which is greater than the proportion
received by any other Bank in respect of the aggregate amount of principal and
interest due with respect to any Note held by such other Bank, the Bank
receiving such proportionately greater payment shall purchase such
participations in the Notes held by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Banks shall be shared by the
Banks pro rata; provided that nothing in this Section shall impair the right of
any Bank 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 Note, 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.

                                      55
<PAGE>   61
         SECTION 11.05.  Amendments and Waivers.  Any provision of this
Agreement or the Notes may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Borrowers and the Required Banks
(and, if the rights or duties of the Agent are affected thereby, by the Agent);
provided that no such amendment or waiver shall, unless signed by all the
Banks, (i) increase or decrease the Commitment of any Bank (except for a
ratable decrease in the Commitments of all Banks) or subject any Bank to any
additional obligation, (ii) reduce the principal of or rate of interest on any
Loan or any fees hereunder, (iii) postpone the date fixed for any payment of
principal of or interest on any Loan or any fees hereunder or for any reduction
or termination of any Commitment, (iv) change the aggregate amount by which or
to which the Commitments are required to be reduced on or prior to any
Commitment Reduction Date or (v) change the percentage of the Commitments or of
the aggregate unpaid principal amount of the Notes, or the number of Banks,
which shall be required for the Banks or any of them to take any action under
this Section or any other provision of this Agreement.

         SECTION 11.06. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that neither Borrower may
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

         (b)     Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment
or any or all of its Loans.  In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrowers and the Agent, such Bank 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 Bank in connection with such Bank's rights
and obligations under this Agreement.  Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrowers hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
that such participation agreement may provide that such Bank will not agree to
any modification, amendment or waiver of this Agreement described in clause
(i), (ii), (iii) or (iv) of Section 11.05 without the consent of the
Participant. The Borrowers agree that each Participant shall, to the extent
provided in its participation agreement, be entitled to the benefits of Article
VIII with respect to its participating interest.  An assignment or other
transfer which is not

                                      56
<PAGE>   62
permitted by subsection (c) or (d) below shall be given effect for purposes of 
this Agreement only to the extent of a participating interest granted in 
accordance with this subsection (b).

         (c)     Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part (equivalent to
an initial Commitment of not less than $10,000,000) of all, of its rights and
obligations under this Agreement and the Notes, and such Assignee shall assume
such rights and obligations, pursuant to an Assignment and Assumption Agreement
in substantially the form of Exhibit H hereto executed by such Assignee and
such transferor Bank, with (and subject to) the subscribed consent of the
Company and the Agent; provided that if an Assignee is an Affiliate of such
transferor Bank or was a Bank immediately prior to such assignment, no such
consent shall be required; and provided further that such assignment may, but
need not, include rights of the transferor Bank in respect of outstanding Money
Market Loans.  Upon execution and delivery of such instrument and payment by
such Assignee to such transferor Bank of an amount equal to the purchase price
agreed between such transferor Bank and such Assignee, such Assignee shall be a
Bank party to this Agreement and shall have all the rights and obligations of a
Bank with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required. Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Bank, the Agent and the Borrowers shall make appropriate
arrangements so that, if required, new Notes are issued to the Assignee.  In
connection with any such assignment, the transferor Bank shall pay to the Agent
an administrative fee for processing such assignment in the amount of $2,500.
If the Assignee is not incorporated under the laws of the United States of
America or a state thereof, it shall deliver to the Borrowers and the Agent
certification as to exemption from deduction or withholding of any United
States federal income taxes in accordance with Section 8.04.

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

         (e)     No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under Section 8.03 or
8.04 than such Bank would have been entitled to receive with respect to the
rights transferred, unless such transfer is made with the Company's prior
written consent or by reason of the

                                      57
<PAGE>   63
provisions of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a
different Applicable Lending Office under certain circumstances or at a time
when the circumstances giving rise to such greater payment did not exist.

         SECTION 11.07. Collateral.  Each of the Banks represents to the Agent
and each of the other Banks that it in good faith is not relying upon any
"margin stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement,

         SECTION 11.08. Governing Law; Submission to Jurisdiction. This
Agreement and each Note shall be governed by and construed in accordance with
the laws of the State of New York.  Each Borrower hereby submits to the
nonexclusive jurisdiction of the United States District Court for the Southern
District of New York and of any New York State court sitting in New York City
for purposes of all legal proceedings arising out of or relating to this
Agreement or the transactions contemplated hereby.  Each Borrower irrevocably
waives, to the fullest extent permitted by law, any objection which it may now
or hereafter have to the laying of the venue of any such proceeding brought in
such a court and any claim that any such proceeding brought in such a court has
been brought in an inconvenient forum.

         SECTION 11.09. Counterparts; Integration; Effectiveness.  This
Agreement may be signed in any number of counterparts, each of which shall be
an original, with the same effect as if the signatures thereto and hereto were
upon the same instrument.  This Agreement constitutes the entire agreement and
understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof.  This Agreement shall become effective upon

                                      58
<PAGE>   64
receipt by the Agent of counterparts hereof signed by each of the parties
hereto (or, in the case of any party as to which an executed counterpart
shall not have been received, receipt by the Agent in form satisfactory to it
of telegraphic, telex, facsimile or other written confirmation from such party
of execution of a counterpart hereof by such party),

         SECTION 11.10. WAIVER OF JURY TRIAL, EACH OF THE BORROWERS, THE AGENT
AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

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

                                   OPINION OF
                            COUNSEL FOR THE BORROWER




To the Banks and the Agent 
  Referred to Below 
c/o Morgan Guaranty Trust Company
  of New York, as Agent 
60 Wall Street
New York, New York 10260

Dear Sirs:

               We have acted as counsel for Morrison Knudsen Corporation, a
Delaware corporation, and Morrison Knudsen Corporation, an Ohio corporation
(the "Borrowers"), in connection with the Credit Agreement (the "Credit
Agreement") dated as of March 31, 1994 among the Borrowers, the banks listed on
the signature pages thereof and Morgan Guaranty Trust Company of New York, as
Agent.  Terms defined in the Credit Agreement are used herein as therein
defined.  This opinion is being rendered to you at the request of our clients
pursuant to Section 3.01(b) of the Credit Agreement.

               We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as we have deemed necessary or advisable
for purposes of this opinion.

               Upon the basis of the foregoing, we are of the opinion that:

               1.  Each Borrower is a corporation duly incorporated, validly
existing and in good standing under the laws of its jurisdiction of
incorporation, and has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted.

               2.  The execution, delivery and performance by each Borrower of
the Credit Agreement and its Notes are within its corporate powers, have been
duly authorized by all necessary corporate action, require no action by or in
respect of, or filing with, any governmental body, agency or 


<PAGE>   88
official and do not contravene, or constitute a default under, any provision of
applicable law or regulation or of the certificate of incorporation or by-laws
of either Borrower or of any agreement, judgment, injunction, order, decree or
other instrument binding upon the Company or any of its Consolidated
Subsidiaries or result in the creation or imposition of any Lien on any asset
of the Company or any of its Consolidated Subsidiaries.

           3.  The Credit Agreement constitutes a valid and binding agreement
of each Borrower and each Note of each Borrower constitutes a valid and binding
obligation of such Borrower, in each case enforceable in accordance with its
terms, except as the same may be limited by bankruptcy, insolvency or similar
laws affecting creditors rights generally and by general principles of equity.

           4.  There is no action, suit or proceeding pending against, or to
the best of our knowledge threatened against or affecting, the Company or any
of its Consolidated Subsidiaries before any court or arbitrator or any
governmental body, agency or official, in which there is a reasonable
possibility of an adverse decision which could materially adversely affect the
business, consolidated financial position or consolidated results of operations
of the Company and its Consolidated Subsidiaries, considered as a whole or
which in any manner draws into question the validity of the Credit Agreement or
the Notes.

           5.  Each of the Borrower's 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.


                               Very truly yours,

                                   OPINION OF
                     DAVIS POLK & WARDWELL, SPECIAL COUNSEL
                                 FOR THE AGENT




To the Banks and the Agent 
   Referred to Below 
c/o Morgan Guaranty Trust Company 
   of New York, as Agent 
60 Wall Street 
New York, New York 10260

Dear Sirs:

               We have participated in the preparation of the Credit Agreement
(the "Credit Agreement") dated as of March 31, 1994 among Morrison Knudsen
Corporation, a Delaware corporation, and Morrison Knudsen Corporation, an Ohio
corporation (the "Borrowers"), the banks listed on the signature pages thereof
(the "Banks") and Morgan Guaranty Trust Company of New York, as Agent (the
"Agent"), and have acted as special counsel for the Agent for the purpose of
rendering this opinion pursuant to Section 3.01(c) of the Credit Agreement.
Terms defined in the Credit Agreement are used herein as therein defined.

               We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as we have deemed necessary or advisable
for purposes of this opinion.

               Upon the basis of the foregoing, we are of the opinion that:

               1. The execution, delivery and performance by the Company of the
Credit Agreement and its Notes are within the Company's corporate powers and
have been duly authorized by all necessary corporate action.

               2. The Credit Agreement constitutes a valid and binding agreement
of each Borrower and each Note of each Borrower constitutes a valid and binding
obligation of such 

<PAGE>   90
Borrower, in each case enforceable in accordance with its
terms, except as the same may be limited by bankruptcy, insolvency or similar
laws affecting creditors' rights generally and by general principles of equity.

               We are members of the Bar of the State of New York and the
foregoing opinion is limited to the laws of the State of New York, the federal
laws of the United States of America and the General Corporation Law of the
State of Delaware.  In giving the foregoing opinion, (i) we have assumed,
without independent investigation, that the execution, delivery and performance
by MK-Ohio of the Credit Agreement and its Notes are within its corporate power
and have been duly authorized by all necessary corporate action and (ii) we
express no opinion as to the effect (if any) of any law of any jurisdiction
(except the State of New York) in which any Bank is located which limits the
rate of interest that such Bank may charge or collect.

               We express no opinion as to the applicability (and, if
applicable, the effect) of Section 548 of the United States Bankruptcy Code or
any comparable provision of state law to the questions addressed above or the
conclusions expressed with respect thereto.

               This opinion is rendered solely to you in connection with the
above matter.  This opinion may not be relied upon by you for any other purpose
or relied upon by or furnished to any other person without our prior written
consent.

                                                        Very truly yours,

                      ASSIGNMENT AND ASSUMPTION AGREEMENT




                      AGREEMENT dated as of            , 19   among [ASSIGNOR]
  (the "Assignor"), [ASSIGNEE] (the Assignee"), MORRISON KNUDSEN CORPORATION, a
  Delaware corporation (the "Company"), and MORGAN GUARANTY TRUST COMPANY OF
  NEW YORK, as Agent (the "Agent"),


                              W I T N E S S E T H


             WHEREAS, this Assignment and Assumption Agreement (the 
"Agreement") relates to the Credit Agreement dated as of ______________, 1994 
among the Company, Morrison Knudsen Corporation,            a Delaware 
Corporation, Morrison Knudsen Corporation,            an Ohio Corporation, 
the Assignor and the other Banks party thereto, as Banks, and the Agent 
(the "Credit Agreement");

             WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Borrowers in an aggregate principal amount at
any time outstanding not to exceed $__________;

             WHEREAS, Committed Loans made to the Borrowers by the Assignor 
under the Credit Agreement in the aggregate principal amount of $_________ are
outstanding at the date hereof; and

             WHEREAS, the Assignor proposes to assign to the Assignee all of the
rights of the Assignor under the Credit Agreement in respect of a portion of
its Commitment thereunder in an amount equal to $______________ (the "Assigned
Amount"), together with a corresponding portion of its outstanding Committed
Loans, and the Assignee proposes to accept assignment of such rights and
assume the corresponding obligations from the Assignor on such terms;

             NOW, THEREFORE, in consideration of the foregoing and the mutual 
agreements contained herein, the parties hereto agree as follows:

             SECTION 1. Definitions.  All capitalized terms not otherwise 
defined herein shall have the respective meanings set forth in the Credit 
Agreement.


<PAGE>   92
               SECTION 2. Assignment.  The Assignor hereby assigns and sells to
the Assignee all of the rights of the Assignor under the Credit Agreement to
the extent of the Assigned Amount, and the Assignee hereby accepts such
assignment from the Assignor and assumes all of the obligations of the Assignor
under the Credit Agreement to the extent of the Assigned Amount, including the
purchase from the Assignor of the corresponding portion of the principal amount
of the Committed Loans made by the Assignor outstanding at the date hereof.
Upon the execution and delivery hereof by the Assignor, the Assignee, the
Company and the Agent and the payment of the amounts specified in Section 3
required to be paid on the date hereof (i) the Assignee shall, as of the date
hereof, succeed to the rights and be obligated to perform the obligations of a
Bank under the Credit Agreement with a Commitment in an amount equal to the
Assigned Amount, and (ii) the Commitment of the Assignor shall, as of the date
hereof, be reduced by a like amount and the Assignor released from its
obligations under the Credit Agreement to the extent such obligations have been
assumed by the Assignee.  The assignment provided for herein shall be without
recourse to the Assignor.

               SECTION 3. Payments.  As consideration for the assignment and
sale contemplated in Section 2 hereof, the Assignee shall pay to the Assignor
on the date hereof in Federal funds the amount heretofore agreed between them.*
It is understood that commitment and/or facility fees accrued to the date
hereof are for the account of the Assignor and such fees accruing from and
including the date hereof are for the account of the Assignee.  Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under
the Credit Agreement which is for the account of the other party hereto, it
shall receive the same for the account of such other party to the extent of
such other party's interest therein and shall promptly pay the same to such
other party.

               SECTION 4. Consent of the Company and the Agent.  This Agreement
is conditioned upon the consent of the Company and the Agent pursuant to
Section 11.06(c) of the Credit Agreement.  The execution of this Agreement by
the Company and the Agent is evidence of this consent.


- -----------------
               * Amount should combine principal together with accrued interest
and breakage compensation, if any, to be paid by the Assignee, net of any
portion of any upfront fee to be paid by the Assignor to the Assignee.  It may
be preferable in an appropriate case to specify these amounts generically or by
formula rather than as a fixed sum.

<PAGE>   93
               SECTION 5. Non-Reliance on Assignor.  The Assignor makes no 
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Borrowers, or the validity and enforceability of the obligations of the
Borrowers in respect of the Credit Agreement or any Note.  The Assignee
acknowledges that it has, independently and without reliance on the Assignor,
and based on such documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement and will
continue to be responsible for making its own independent appraisal of the
business, affairs and financial condition of the Borrower.

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

               SECTION 7. Counterparts.  This Agreement may be signed in any 
number of counterparts, each of which shall be an original, with the same 
effect as if the signatures thereto and hereto were upon the same instrument.

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

<PAGE>   25
         Letter of Credit, that one or more of the applicable conditions

         not accept the Letter of Credit as amended.

before the Business Day immediately preceding the date the Issuing Bank is to
amend the Letter of Credit (A) from the Agent directing the Issuing Bank not to
issue such amendment to the Letter of Credit because such amendment would cause
the Available Amount to exceed the Maximum Amount; or (B) from the Agent or any
Bank that one or more applicable conditions specified in Section 4.02(b) or (c)
are not then satisfied; then, subject to the terms and conditions hereof, the
Issuing Bank will, on the requested date, amend the Letter of Credit in

                 (c)      The Agent will promptly (i) notify the Banks of the

                 (a)      Immediately upon the effectiveness of this Agreement
and upon each amendment of the Letter of Credit pursuant to Section 2.02, each
Bank (other than the Issuing Bank) shall be deemed to, and hereby irrevocably
and unconditionally agrees to, purchase from the Issuing Bank a participation
in the Letter of Credit and each drawing thereunder in an amount equal to the
product of (i) the Commitment Percentage of such Bank, times (ii) the Available
Amount of the Letter of Credit at the time of such issuance or amendment;
provided that the amount of each Bank's participation shall not exceed such
Bank's Commitment Amount.

                 (b)      The Company shall reimburse the Issuing Bank for the
full amount of any drawing under the Letter of Credit.  The Company shall
notify the Agent by 10:00 a.m. (San Francisco time) on the date of a drawing
under the Letter of Credit whether the Company will reimburse the Issuing Bank
in full on the date of such drawing, and the Agent shall promptly notify 


                                       19
<PAGE>   26
the Banks of the amount of such drawing and the contents of such notice.  If the
Company notifies the Agent prior to such time that it will reimburse the
Issuing Bank in the full amount of such drawing on the date of such drawing,
then the Company shall pay to the Issuing Bank the full amount of such drawing
no later than 11:00 a.m. (San Francisco time) on the date of such drawing.  In
the event that the Company does not so notify the Agent by 10:00 a.m. (San
Francisco time) on the date of such drawing that it intends to reimburse such
drawing on such date, or in the event that the Company fails to reimburse the
Issuing Bank the full amount of any drawing by 11:00 a.m. (San Francisco time)
on the date of such drawing, then the Company shall be deemed to have incurred
an L/C Borrowing in the principal amount of such drawing, and the Issuing Bank
shall be deemed to have made a loan to the Company in the principal amount of
such drawing (provided that no L/C Borrowing shall be permitted, and the full
amount of each drawing shall be immediately reimbursed to the Issuing Bank, if
any Default or Event of Default shall have occurred and be continuing).  Each
L/C Borrowing shall be due and payable on demand made by the Agent (together
with interest from the date of such drawing) and shall bear interest until
such demand at a rate per annum equal to the Reference Rate plus one percent
(1.0%), provided, however, that at least one day of such interest on the amount
of such drawing shall be payable even if the Company reimburses the Issuing
Bank, on the date of such drawing, in the full amount of such drawing.  The
Agent shall demand payment in full of each L/C Borrowing on the Business Day
immediately following the drawing under the Letter of Credit which gave rise to
such L/C Borrowing, unless the date for such demand is extended by the Banks in
accordance with the provisions of Section 10.01(b). Any notice given by the
Issuing Bank or the Agent pursuant hereto may be oral if immediately confirmed
in writing (including by facsimile).

                 (c)      Each Bank will, upon receipt of any notice pursuant
to subsection 2.03(b) of an L/C Borrowing or other unreimbursed drawing under
the Letter of Credit, make available to the Agent for the account of the
Issuing Bank an amount in immediately available funds equal to such Bank's
Commitment Percentage of the amount of the relevant drawing, whereupon the
participating Banks shall each be deemed to have made a payment in satisfaction
of its participation obligation under subsection 2.03(a). If any Bank is
notified by 11:00 a.m. (San Francisco time) on the date of a drawing that there
has been a drawing under the Letter of Credit and that the Company intends to
or will incur an L/C Borrowing, then such Bank shall make available to the
Agent for the account of the Issuing Bank, no later than 1:00 p.m. (San
Francisco time) on the date of such drawing, such Bank's Commitment Percentage
of such L/C Borrowing.  If a Bank is notified of a drawing after 11:00 a.m.
(San Francisco time) on the date of such drawing, then such Bank shall make
available to the Agent for the account of the Issuing Bank such Bank's


                                       20
<PAGE>   27
Commitment Percentage of such L/C Borrowing no later than 1:00 p.m. (San
Francisco time) on the Business Day immediately following the date of such
drawing.  If any Bank notified (at any time) of any L/C Borrowing shall fail,
for any reason whatsoever, to make available to the Agent for the account of
the Issuing Bank the amount of such Bank's Commitment Percentage of such L/C
Borrowing by no later than 1:00 p.m. (San Francisco time) on the date such
drawing was honored by the Issuing Bank (the "Participation Date" with respect
to such drawing), then interest shall accrue on such Bank's obligation to make
such payment, for the account of the Issuing Bank, from the Participation Date
through the date which is one Business Day after the date such drawing was
honored by the Issuing Bank, at a rate per annum equal to the Federal Funds
Rate in effect from time to time.  The Agent will promptly give notice to the
Banks of the occurrence of the Participation Date, but failure of the Agent to
give any such notice on the Participation Date or in sufficient time to enable
any Bank to effect such payment on such date shall not relieve such Bank from
its obligations under this Section 2.03 to purchase and pay for a participation
in the drawing giving rise to such Participation Date.

                 (d)      IN DETERMINING WHETHER TO PAY UNDER THE LETTER OF
CREDIT, THE ISSUING BANK SHALL BE RESPONSIBLE ONLY TO DETERMINE THAT THE
DOCUMENTS AND CERTIFICATES REQUIRED TO BE DELIVERED UNDER THE LETTER OF CREDIT
HAVE BEEN DELIVERED AND THAT THEY COMPLY ON THEIR FACE WITH THE REQUIREMENTS OF
THE LETTER OF CREDIT.

         2.04    Repayment of Participations.

                 (a)      Upon (and only upon) receipt  by the Agent for the
account of the Issuing Bank of funds from the Company (i) in reimbursement of
any payment made by the Issuing Bank under the Letter of Credit with respect to
which any Bank has theretofore paid the Agent for the account of the Issuing
Bank for such Bank's participation in the Letter of Credit pursuant to Section
2.03, or (ii) in payment of interest thereon; the Agent will pay to each Bank
such Bank's Commitment Percentage share of such funds (subject to the other
provisions of this Section 2.04(a)), and the Issuing Bank shall receive the
Commitment Percentage share of any Bank that did not so pay the Agent for the
account of the Issuing Bank (including such Bank's Commitment Percentage of any
interest accruing on such L/C Borrowing or other unreimbursed drawing).  If any
Bank shall fail to make available to the Agent its Commitment Percentage of an
L/C Borrowing or other unreimbursed drawing by 1:00 p.m. (San Francisco time)
on the Business Day immediately following the date of the relevant drawing,
then such Bank's Commitment Percentage of any interest accruing on such L/C
Borrowing or other unreimbursed drawing from 1:00 p.m. (San Francisco time) 
on the Business Day immediately following the date of such drawing to the date
such


                                       21
<PAGE>   28
Bank makes available its Commitment Percentage of such L/C Borrowing or other
unreimbursed drawing to the Agent, shall be payable to the Issuing Bank. 
Nothing in this Section 2.04(a) shall relieve any Bank of any of its
obligations under Section 2.03.

                 (b)      If the Agent or the Issuing Bank is required at any
time to return to the Company or to a trustee, receiver, liquidator, custodian,
or any official in any Insolvency Proceeding, any portion of the payments made
by the Company to the Agent for the account of the Issuing Bank pursuant to
subsection 2.04 (a) in reimbursement of a payment made under the Letter of
Credit or interest thereon, each Bank shall, on demand of the Agent, forthwith
return to the Agent or the Issuing Bank its Commitment Percentage share of any
amounts so returned by the Agent or the Issuing Bank plus interest thereon from
the date such demand is made to the date such amounts are returned by such Bank
to the Agent or the Issuing Bank, at a rate per annum equal to the Federal
Funds Rate in effect from time to time.

         2.05    Role of the Issuing Bank.

                 (a)      Each Bank agrees that, in paying any drawing under
the Letter of Credit, the Issuing Bank shall not have any responsibility to
obtain any document (other than a demand for payment expressly required by the
Letter of Credit) or to ascertain or inquire as to the validity or accuracy of
any such document or the authority of the Person executing or delivering any
such document.  Neither the Issuing Bank nor any of its Affiliates,
correspondents, participants or assignees, or any of their respective officers,
directors or employees, shall be liable to any Bank for:

                          (i)     any action taken or omitted in connection
         herewith at the request or with the approval of the Banks (including
         the Majority Banks, as applicable);

                          (ii)    any action taken or omitted in the absence of
         gross negligence or wilful misconduct; or

                          (iii)   the due execution, effectiveness, validity or
         enforceability of any L/C Related Document.

                 (b)      The Company hereby assumes all risks of the acts or
omissions of any beneficiary or transferee with respect to its use of the
Letter of Credit; provided, however, that this assumption is not intended to,
and shall not, preclude the Company's pursuing such rights and remedies as it
may have against the beneficiary or transferee at law or under any other
agreement.  Neither the Issuing Bank, nor any of its Affiliates,
correspondents, participants or assignees, or any of their


                                       22
<PAGE>   29
respective officers, directors or employees, shall be liable or responsible 
for any of the matters described in paragraphs (i) through (vii) of Section 
2.06; provided, however, anything in such clauses to the contrary 
notwithstanding, that the Company may have a claim against the Issuing Bank, 
and the Issuing Bank may be liable to the Company, to the extent, but only to
the extent, of any direct, as opposed to consequential or exemplary, damages
suffered by the Company which the Company proves were caused by (i) the 
Issuing Bank's willful misconduct or gross negligence or (ii) the Issuing 
Bank's willful failure to pay under the Letter of Credit after the presentation
to it by the beneficiary of a demand for payment strictly complying with the
terms and conditions of the Letter of Credit except where the failure to 
pay results from the Issuing Bank's attempts to comply with any Requirement of
Law.  In furtherance and not in limitation of the foregoing, the Issuing Bank
may accept documents that appear on their face to be in order, without 
responsibility for further investigation, regardless of any notice or 
information to the contrary.

         2.06    Obligations Absolute.  The obligations of the Company under
this Agreement and any L/C Related Document to reimburse the Issuing Bank, and
to repay L/C Borrowings, shall be unconditional and irrevocable, and shall be
paid strictly in accordance with the terms of this Agreement and such other L/C
Related Document under all circumstances, including the following:

                 (i)      any lack of validity or enforceability of this
         Agreement, the Letter of Credit or any other L/C Related Document;

                 (ii)     any change in the time, manner or  place of payment
         of, or in any other term of, all or any of the obligations of the
         Company in respect of the Letter of Credit or any other amendment or
         waiver of or any consent to departure from all or any of the L/C
         Related Documents;

                 (iii)    the existence of any claim, set-off, defense or other
         right that the Company may have at any time against any beneficiary or
         any transferee of the Letter of Credit (or any Person for whom any
         such beneficiary or any such transferee may be acting), the Issuing
         Bank or any other Person, whether in connection with this Agreement,
         the transactions contemplated hereby or by the L/C Related Documents
         or any unrelated transaction;

                 (iv)     any certificate or other document presented under the
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;


                                       23
<PAGE>   30
                 (v)      any payment by the Issuing Bank under the Letter of
         Credit against presentation of a demand for payment, draft or
         certificate that does not strictly comply with the terms of the Letter
         of Credit; or any payment is made by the Issuing Bank under the Letter
         of Credit to any Person purporting to be a trustee in bankruptcy,
         debtor-in-possession, assignee for the benefit of creditors,
         liquidator, receiver or other representative of or successor to any
         beneficiary or any transferee of the Letter of Credit, including any
         arising in connection with any Insolvency Proceeding;

                 (vi)     any release or amendment or waiver of or consent to
         departure from any guarantee for all or any of the obligations of the
         Company in respect of the Letter of Credit; or

                 (vii)    any other circumstance or happening whatsoever,
         whether or not similar to any of the foregoing, including any other
         circumstance that might otherwise constitute a defense available to,
         or a discharge of, the Company or a guarantor.

         2.07    Cash Collateral Pledge.  Upon the request of the Agent, if, as
of the Termination Date, the Letter of Credit may for any reason remain
outstanding and partially or wholly undrawn, the Company shall immediately pay
over, pledge and deliver, pursuant to a pledge and security agreement in the
form of Exhibit 2.07, cash in an amount equal to the Outstanding Amount, to the
Agent for the benefit of the Banks as collateral for the Company's obligations
under this Agreement and the other L/C Related Documents.

         2.08    Letter of Credit Fees. (a) The Company shall pay to the Agent
for the account of the Banks, letter of credit fees equal to 0.40% per annum of
the average daily amount of the Available Amount.  Such fees shall accrue from
the Closing Date to the Termination Date, and shall be payable quarterly in
arrears on the last day of each calendar quarter, commencing with the calendar
quarter ending September 30, 1992, and on the Termination Date.

                 (b)      The Company shall pay the Issuing Bank, for the
account of the Issuing Bank, a letter of credit fronting fee in the amount and
at the times set forth in a letter agreement between the Company and the
Issuing Bank.


                                       24
<PAGE>   31
         2.09    Additional Fees.

                 (a)      Arrangement Fee.  The Company shall pay to the Agent
for the Agent's own account an arrangement fee in the amount and at the times
set forth in a letter agreement between the Company and the Agent.

                 (b)      Commitment Fees.  The Company shall pay to the Agent
for the account of each Bank a commitment fee in the amount of 0.30 percent
(0.30%) per annum on the average daily amount of the Unavailable Portion.  Such
commitment fee shall accrue from Closing Date to the Termination Date and shall
be payable quarterly in arrears on the last day of each calendar quarter,
commencing with the calendar quarter ending September 30, 1992, and on the
Termination Date.

         2.10    Computation of Fees and Interest.

                 (a)      All computations of fees 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.

                 (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.

         2.11    Payments by the Company.

                 (a)      All payments (including prepayments) to be made by
the Company on account of reimbursements, 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 of a
drawing under the Letter of Credit, in the case of reimbursement, and otherwise
on such other date when due.  In the case of reimbursements, interest, fees and
other amounts which are paid to the Agent for the account or benefit of all of
the Banks the Agent will promptly distribute such payments to each Bank
(subject to the provisions of Section 2.04) its Commitment Percentage of such
reimbursements, interest, fees, or other amounts, in like funds as received.
In the case of fees and other amounts which are paid to the Agent for the
account or


                                       25
<PAGE>   32
benefit of the Issuing Bank or the Agent, the Agent will promptly distribute
such payments to the Issuing Bank or the Agent, as appropriate, such 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 reimbursement, L/C Borrowing,
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
reimbursement, L/C Borrowing, interest, fee or other amount shall thereafter
bear interest at the rate of the Reference Rate plus 3%.

         2.12    Payments by the Banks to the Agent.

                 (a)      Except to the extent otherwise specifically provided
herein, the Agent may assume that each Bank has made available to the Agent on
the date of any L/C Borrowing the amount of such Bank's Commitment Percentage
of such L/C Borrowing, and the Agent may (but shall not be so required), in
reliance upon such assumption, make available to the Issuing Bank on such date
a corresponding amount.  If and to the extent any Bank shall not have made its
full amount available to the Agent and the Agent in such circumstances has made
available to the Issuing Bank such amount, that Bank shall on the next 
Business Day following the date of such L/C Borrowing make such amount
available to the Agent, together with interest at the Federal Funds Rate for
each day during such period.  A certificate of the Agent submitted to any Bank
with respect to amounts owing under this subsection 2.12(a) shall be
conclusive, absent manifest error.  If such amount is so made available, such
payment to the Agent shall constitute such Bank's payment to the Issuing Bank
pursuant to Section 2.03(c) on the date of such L/C Borrowing for all purposes
of this Agreement.

                 (b)      The failure of any Bank to make any payments due to
the Issuing Bank with respect to an L/C Borrowing on the date of such L/C
Borrowing shall not relieve such Bank or any other Bank of any obligation
hereunder to pay the sums due from such other Bank with respect to such L/C
Borrowing pursuant to Section 2.03, but no Bank shall be responsible for the
failure of any other Bank to make any such payment to be made by such other
Bank on the date of any L/C Borrowing.

<PAGE>   33
         2.13    Sharing of Payments, Etc.  If, other than as expressly
contemplated herein, any Bank shall obtain on account of the Letter of Credit
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 the Letter of Credit 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 L/C
Borrowings 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 2.13 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 2.13 or in a refund under this
Section 2.13 shall notify the Agent of the details of such purchase or refund.
The Agent shall keep records (which shall be conclusive and binding in the
absence of manifest error), of participations purchased pursuant to this
Section 2.13 and shall in each case notify the Banks following any such
purchases.

         2.14    Guaranty.  All obligations of the Company under this Agreement
and all other L/C Related Documents shall be unconditionally guaranteed by the
Guarantor pursuant to a guaranty and agreement (the "Guaranty") in the form of
Exhibit 2.14 attached hereto.

                                  ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01    Taxes.

                 (a)      Subject to subsection 3.01(g), any and all payments
by the Company to each Bank or the Agent under this Agreement shall be made
free and clear of, and without deduction or withholding for, any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all


                                       27
<PAGE>   34
liabilities with respect thereto, excluding, in the case of each Bank
and the Agent, such taxes (including income taxes or franchise taxes) as are
imposed on or measured by each Bank's or the Agent's net income by the
jurisdiction under the laws of which such Bank or the Agent, as the case may
be, is organized or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").

                 (b)      In addition, the Company shall pay any present or
future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other L/C Related Documents (hereinafter referred to as "Other
Taxes").

                 (c)      Subject to subsection 3.01(g), the Company shall
indemnify and hold harmless each Bank and the Agent for the full amount of
Taxes or Other Taxes (including without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 3.01) paid by
the Bank or the Agent and any liability (including penalties, interest,
additions to tax and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted.
Payment under this indemnification shall be made within 30 days from the date
the Bank or the Agent makes written demand therefor.

                 (d)      If the Company shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to any Bank or the Agent, then, subject to subsection 3.01(g):

                          (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
         3.01) such Bank or the Agent, as the case may be, receives an amount
         equal to the sum it would have received had no such deductions been
         made;

                          (ii)    the Company shall make such deductions, and

                          (iii)   the Company shall pay the full amount
         deducted to the relevant taxation authority or other authority in
         accordance with applicable law.

                 (e)       Within 30 days after the date of any payment by the
Company of Taxes or Other Taxes, the Company shall furnish to the Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to the Agent.

<PAGE>   35
                 (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 payments 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
         payments 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.

<PAGE>   36
                 (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:

                          (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


                                       30
<PAGE>   37
such change in the judgment of such Bank is not otherwise disadvantageous to
such Bank.

                 (j)      If the Internal Revenue Service or any other Federal,
state, 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 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
to 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 the Letter of Credit, any L/C
Borrowings, or other unreimbursed drawings, 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


                                       31
<PAGE>   38
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.

                 (c)      If any Governmental Authority shall require that any
Bank treat the Letter of Credit as a financial letter of credit rather than as
a performance letter of credit, and if there shall be any increase in the cost
to such Bank of agreeing to issue, amend, maintain, fund, or participate in the
Letter of Credit, any unreimbursed drawings, or any L/C Borrowings, 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 determined by such Bank, as
are sufficient to compensate such Bank for such increased costs.

         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 setting forth in reasonable detail the amount
payable to the Bank hereunder and such certificate shall be conclusive and
binding on the Company in the absence of manifest error.

         3.04    Survival.  The agreements and obligations of the Company
contained in this Article III and of the Banks contained in Section 3.01(j)
shall survive the payment in full of all other obligations of the Company under
this Agreement.

         3.05    Replacement of Banks.  If any Bank (a "Notice Bank) makes
demand for amounts owed under Section 3.02, then the Company, with the consent
of the Agent, shall have the right, if no Default or Event of Default exists,
and subject to the terms and conditions set forth in Section 10.08, to
designate any Eligible Assignee (a "Replacement Bank") to purchase the Notice
Bank's participation in the Letter of Credit, the drawings thereunder and L/C
Borrowings, interest thereon, and fees and to assume the Notice Bank's
obligations to the Company under this Agreement.  Such purchase shall be at a
price equal to the Notice Bank's Commitment Percentage of such drawings and L/C
Borrowings, interest thereon, and fees, all as of the time of such purchase.
Subject to the foregoing, the Notice Bank agrees to assign without recourse to
the Replacement Bank its participation in the Letter of Credit, the drawings
thereunder, L/C Borrowings, and its Commitment, and to delegate to the
Replacement Bank its obligations to the Company under this Agreement and its
future obligations to the Agent under this Agreement.  Upon such sale and
delegation by the Notice Bank and the purchase and assumption by the
Replacement Bank, and compliance with the provisions of Section 10.08, the
Notice Bank


                                       32
<PAGE>   39
shall cease to be a Bank hereunder and the Replacement Bank shall become a 
Bank under this Agreement, providing, however, that to the extent (and
solely to the extent) relating to L/C Borrowings extended, acts or omissions
made, or other matters arising prior to the date of such Notice Bank's sale and
delegation, the Notice Bank shall at all times remain a "Bank" hereunder.

except, in each case referred to in Section 5.01(c) or Section 5.01(d), to the

true and complete in all material respects. The Withdrawal Liabilities
(including such liabilities with respect to Multiemployer Plans not listed on
Schedule 5.07) do not exceed $10,000,000.

                 (b)      Except for Multi-employer Plans not maintained or

in all material respects with the applicable provisions of ERISA, the Code and
other Federal or state law, including all requirements under the Code or ERISA
for filing reports (which are true and correct in all material respects as of
the date filed), except to the extent that non-compliance for all Plans in the
aggregate would not have a Material Adverse Effect, and benefits have been paid
in accordance with the provisions of the Plan.

                 (c)      Except for Multi-employer Plans not maintained or
sponsored by the Company or the Guarantor but to which the Company or the
Guarantor contributes or is obligated to contribute, each Qualified Plan has
been determined by the IRS to qualify under Section 401 of the Code, and the
trusts created thereunder have been determined to be exempt from tax under the
provisions of Section 501 of the Code, and to the best knowledge


                                       38
<PAGE>   45
of the Company nothing has occurred which would cause the loss of such

(as to which the Company or the Guarantor is or may be liable), nor with
respect to any Plan to which the Company or any ERISA Affiliate (wherein the
Company or the Guarantor is or may be liable) contributes or is obligated to
contribute.

                 (e)      Except as set forth on Schedule 5.07, none of the

maintained or sponsored by the Company or the Guarantor provides medical or
other welfare benefits or extends coverage relating to such benefits beyond the
date of a participant's termination of employment with the Company or the
Guarantor, except to the extent required by Section 4980B of the Code and at
the sole expense of the participant or the beneficiary of the participant to
the fullest extent permissible under such Section of the Code. The Company and
Guarantor have complied in all material respects with the notice and
continuation coverage requirements of Section 4980B of the Code.

                 (g)      Except for Multiemployer Plans not maintained by the
Company or the Guarantor but to which the Company or the Guarantor contributes
or is obligated to contribute, and except as set forth in Schedule 5.07, no
ERISA Event has occurred or is reasonably expected to occur with respect to any
Plan maintained or sponsored by the Company or the Guarantor or to which the
Company or the Guarantor is obligated to contribute.

                 (h)      There are no pending or, to the best knowledge of the

respective assets, (ii) any member of the Controlled Group with respect to any
Qualified Plan of the Company or the Guarantor, or (iii) any fiduciary with

Company nor the Guarantor has incurred nor reasonably expects to incur (i) any
liability (and no event has occurred which, with


                                       39
<PAGE>   46
the giving of notice under Section 4219 Of ERISA, would result in such
liability) under Section 4201 or 4243 of ERISA with respect to a Multiemployer
Plan or (ii) any liability under Title IV of ERISA (other than premiums due and
not delinquent under Section 4007 of ERISA) with respect to a Plan.

                 (j)      Except as set forth in Schedule 5.07, neither the
Company nor the Guarantor has transferred any Unfunded Pension Liability
outside of the Controlled Group or otherwise engaged in a transaction that
could be subject to Section 4069 or 4212(c) of ERISA.

                 (k)      Neither the Company nor the Guarantor has engaged,
directly or indirectly, in a non-exempt prohibited transaction (as defined in
Section 4975 of the Code or Section 406 of ERISA) in connection with any Plan

in connection with the execution, delivery, performance or enforcement against
the Company, the Guarantor or any of their respective Subsidiaries of the
Contract or any other documents and agreements related thereto.

                 (c)      The Contract and the other documents and agreements
related thereto which the Company, the Guarantor or any of their respective

                               NEGATIVE COVENANTS

         The Company hereby covenants and Agrees that, so long as any Bank
shall have any Commitment hereunder, or the Letter of Credit is outstanding or
any amount payable hereunder shall remain unpaid, unless the Majority Banks
waive compliance in writing:

         7.01    Limitation on Liens.  The Company shall not, nor shall it

make, create, incur, assume or suffer to exist any Lien upon or with respect to
any part of its or their Property, whether now owned or hereafter acquired,
other than the following ("Permitted Liens"):

                 (b)      Liens for taxes, fees, assessments or other
governmental charges which are not delinquent or remain payable without
penalty, or to the extent that non-payment thereof is permitted by Section

                 (c)      carriers', warehousemen's, mechanics', landlords',
materialmen's, repairmen's or other similar Liens arising in the Ordinary

which proceedings have the effect of preventing the forfeiture or sale of the
Property subject thereto;

                 (d)      Liens (other than any Lien imposed by ERISA)
consisting of pledges or deposits required in the Ordinary Course of Business

<PAGE>   58
contracts (other than for borrowed money), leases, statutory obligations, and
(ii) other obligations of a like nature; in each case, incurred in the ordinary
Course of Business, provided all such Lions in the aggregate would not (even if

                 (f)      Liens consisting of judgment or judicial attachment
liens, provided that the enforcement of such Liens is effectively stayed;

                 (g)      easements, rights-of-way, restrictions and other
similar encumbrances incurred in the Ordinary Course of Business which, in the
aggregate, are not substantial in amount, and which do not in any case
materially detract from the value of the Property subject thereto or interfere
with the ordinary conduct of the businesses of the Guarantor and its
Subsidiaries;

                 (h)      Purchase money security interests on any Property
acquired or held by the Guarantor or its Subsidiaries in the Ordinary Course of
Business, other than any collateral required hereunder, securing Indebtedness
incurred or assumed for the purpose of financing all or any part of the cost of
acquiring such Property; Provided that (i) any such Lien attaches to such
Property concurrently with or within 20 days after the acquisition thereof,
(ii) such Lien attaches solely to the Property so acquired in such transaction,
and (iii) the principal amount of the debt secured thereby does not exceed 100%
of the cost of such Property;

                 (i)      Liens arising from the sale of accounts receivable

described on Exhibit 7.02.

         7.02    Mergers, Consolidations, Purchases and Sales.  The Company
shall not and shall not permit the Guarantor or any of the Guarantor's
Subsidiaries to:

                 (a)      be a party to any merger or consolidation;

                 (b)      transfer, convey, lease or otherwise dispose of all
         or any of the assets of the Guarantor and its Subsidiaries taken as a
         whole, or sell, transfer, convey, lease or otherwise dispose of any
         stock, ownership interest or other equity interest in any Subsidiary
         of the Guarantor, with value in the aggregate for all such sales,
         transfers, conveyances, leases or other disposals per fiscal year of


                                       52
<PAGE>   59
         the Guarantor and its Subsidiaries in excess of the Sale Limit; or

                 (c)      sell or assign, with or without recourse, any
         accounts receivable or chattel paper, in excess for the aggregate face
         amount of all accounts receivable or chattel paper sold and
         outstanding at any one time of $100,000,000, excluding the sales of
         chattel paper on June 26, 1992, pursuant to an agreement with
         Burlington Northern Railroad Company, aggregating not more than
         $27,200,000, as such sales are more particularly described on Exhibit
         7.02.

Notwithstanding the foregoing:

                 (x)      any wholly-owned Subsidiary of the Guarantor may
         merge into the Guarantor or into or with any other wholly-owned
         Subsidiary of the Guarantor;

                 (y)      any wholly-owned Subsidiary of the Guarantor may
         consolidate with any other wholly-owned Subsidiary of the Guarantor so
         long as immediately thereafter 100% of the voting stock or other
         ownership interest of the resulting Person is owned by the Guarantor
         or another wholly-owned Subsidiary of the Guarantor; and

                 (z)      any wholly-owned Subsidiary of the Guarantor may
         sell, transfer, convey, lease or assign all or a substantial part of
         its assets to the Guarantor or to a wholly-owned Subsidiary of the
         Guarantor;

provided, however, in each of the cases described in the preceding clauses (x),
(y), and (z), that (A) immediately thereafter and after giving effect thereto,
no Default or Event of Default shall have occurred and be continuing, and (B)
prior thereto, in any such case involving the Company where the Company is not
the surviving entity, such surviving entity shall assume the obligations of the
Company under this Agreement and the other L/C Related Documents pursuant to an
agreement or document in form and substance satisfactory to the Agent and all
of the Banks, and the Guarantor shall reaffirm its obligations under the
Guaranty pursuant to an agreement or document in form and substance
satisfactory to the Majority Banks.

For the purposes of this Section 7.02, "Sale Limit" means an annual amount
equal to 25% of Consolidated Tangible Net Worth determined as of the end of the
immediately preceding fiscal year of the Guarantor. The term "value" means,
with respect to any asset, stock or other ownership or equity interest disposed
of, the greater of such item's book or fair market value (or the fair market
value, if book value is not applicable) as of the date of disposition, with
"book value" being the value of such item as would appear immediately prior to
such disposition on a


                                       53
<PAGE>   60
balance sheet of the owner of such item prepared in accordance with GAAP.

         7.03    Transactions with Affiliates.  The Company shall not and shall
not permit the Guarantor or any of its Subsidiaries to enter into any
transaction with any Affiliate of the Company or of any such Subsidiary except
as contemplated by this Agreement or in the ordinary course of business and
pursuant to the reasonable requirements of the business of the Company or such
Subsidiary and upon fair and reasonable terms no less favorable to the Company
or such Subsidiary than would obtain in a comparable arm's-length transaction
with a Person not an Affiliate of the Company or such Subsidiary.

         7.04    Compliance with ERISA.  Except to the extent that such would
not result, in the aggregate for all Plans, in a Material Adverse Effect, the
Company shall not directly or indirectly and shall not permit or suffer any
ERISA Affiliate directly or indirectly (i) to terminate, any Plan subject to
Title IV of ERISA so as to result in any material (in the opinion of the
Majority Banks) liability to the Company or any ERISA Affiliate, (ii) to permit
to exist any ERISA Event or any other event or condition, which presents the
risk of a material (in the opinion of the Majority Banks) liability of the
Company or any ERISA Affiliate, or (iii) to make a complete or partial
withdrawal (within the meaning of ERISA Section 4201) from any Multiemployer
Plan so as to result in any material (in the opinion of the Majority Banks)
liability to the Company or any ERISA Affiliate, (iv) to enter into any new
Plan or modify any existing Plan so as to increase its obligations thereunder
except in the ordinary course of business consistent with past practice which
could result in any material (in the opinion of the Majority Banks) liability
to the Company or any ERISA Affiliate, or (v) permit the present value of all
nonforfeitable accrued benefits under each Plan (using the actuarial
assumptions utilized by the PBGC upon termination of a Plan) materially (in the
opinion of the Majority Banks) to exceed the fair market value of Plan assets
allocable to such benefits, all determined as of the most recent valuation date
for each such Plan.

         7.05    Change in Business.  The Company shall not, and shall not
permit any of its Subsidiaries to, engage in any material line of business
substantially different from those lines of business carried on by it on the
date hereof.

         7.06    Change in Structure.  Except as permitted under Section 7.02,
the Company shall not and shall not permit the Guarantor or any of its
Subsidiaries to, make any changes in its capital structure (including, without
limitation, in the terms of its outstanding stock) or amend its certificate of


                                       54
<PAGE>   61
incorporation or by-laws if, as a result, there would be a reasonable
likelihood of having a Material Adverse Change.

         7.07    Accounting Changes.  The Company shall not, and shall not
permit the Guarantor or any of its Subsidiaries to, make any significant change
in accounting treatment and reporting practices, except as required by GAAP, or
change the fiscal year of the Guarantor or any of its Subsidiaries, except, in
the case of a Subsidiary of the Guarantor which become a Subsidiary of the
Guarantor after the date hereof, for a change in the fiscal year of such
Subsidiary to make such Subsidiary's fiscal year the same as that of the
Guarantor.

         7.08    Other Contracts.  The Company shall not enter into any
employment contracts or other arrangements whose terms, including salaries,
benefits and other compensation, are not normal and customary in the industry.

         7.09    Current Ratio.  The Company shall not permit the Guarantor's
consolidated ratio of (i) Consolidated Current Assets to (ii) Consolidated
Current Liabilities, to be less than 1.15 to 1.0 at any time.

         7.10    Consolidated Tangible Net Worth.  The Company shall not permit
the Guarantor's Consolidated Tangible Net Worth at any time to be less than (x)
$300,000,000 plus (y) 40% of consolidated net income earned in those fiscal
quarters for which consolidated net income is positive, and which end after
January 1, 1992, and at or prior to such time.

         7.11    Indebtedness to Tangible Net Worth Ratio.  The Company shall
not permit the Guarantor's ratio of consolidated Indebtedness (excluding the
Guarantor's obligations under the Guaranty and the obligations of the Guarantor
and its Subsidiaries under undrawn standby letters of credit) to Consolidated
Tangible Net Worth to be at any time greater than 1.50 to 1.0.

         7.12    Funded Debt to Tangible Net Worth Ratio.  The Company shall
not permit the Guarantor's ratio of total Consolidated Funded Debt to
Consolidated Tangible Net Worth to be at any time greater than 1.20 to 1.0.

         7.13    Interest Coverage Ratio.  The Company shall not permit the
Guarantor's ratio of (a) the sum of Consolidated Operating Income, Consolidated
Interest Expense, and consolidated provision for income taxes, in each case of
the Guarantor and its Subsidiaries on a consolidated basis, to (b) Consolidated
Interest Expense, for any period of four (4) consecutive fiscal quarters to be
less than 1.5 to 1.0.

Subsidiary shall have set aside on its books such reserves or other appropriate
provisions therefor as may be required by GAAP; or

through (vii) that involves a net increase in aggregate Unfunded Pension

applicable grace period) of any material obligation or agreement of the
Guarantor or any of its Subsidiaries with respect to any L/C Indebtedness.

     8.02        Remedies. If any Event of Default occurs, the Agent shall, at

terminated, whereupon such Commitments shall forthwith be terminated; (b)
declare the unpaid principal amount of all outstanding L/C Borrowings, 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;
(c) with respect to any and all contingent, unmatured, or unliquidated
Obligations, declare and require that cash in an amount equal to the aggregate
amount of such Obligations be paid over and pledged to the Agent pursuant to a
pledge and security agreement in the form of Exhibit 2.07, to be held as
additional cash collateral, in which case such amounts shall be immediately
pledged and delivered to the Agent as demanded by the Agent; or (d) exercise
all rights and remedies available to it under this Agreement or the other L/C
Related Documents or applicable law; provided, however, that upon the
occurrence of any event specified in clause (g) or (h) of Section 8.01 above or
upon the occurrence with respect to the Guarantor of any event described in
paragraphs (g) or (h) of Section 8.01 (in the case of such reference to clause
(h) upon the expiration of the 60 day period mentioned therein), the obligation
of each Bank to issue or amend the Letter of Credit shall automatically
terminate and the unpaid principal amount of all outstanding L/C Borrowings and

exclusive of any other rights, powers, privileges or remedies provided by law
or in equity, or under any other instrument, document or agreement.

     8.04        HLT Status.  If at any time after the Closing Date, for any
reason the Company or the transaction contemplated hereby shall be designated
as a highly leveraged transaction ("HLT") in accordance with the applicable
standards adopted by bank regulatory officials, Agent shall provide the Company
with written notice of such designation and the fees and interest rates payable
by the Company shall be amended to reflect HLT pricing based on amounts being
charged at such time by the Agent for interest and fees on HLT credits ("HLT
Rates").  Agent shall provide the Company with notice of the HLT Rates and the
HLT Rates shall apply for all purposes under this Agreement as of the date the
Company or the transaction contemplated hereby is designated as an HLT.

liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement (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 L/C 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 L/C Related
Document, or the value of any collateral, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other L/C
Related Document, or for any failure of the Company or any other party to any
L/C 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 L/C 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, telecopy, 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 L/C 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 L/C 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 and 4.02, each Bank shall


                                       61
<PAGE>   68
be deemed to have consented to, approved or accepted or to be satisfied with
each document or other matter required thereunder to be consented to or
approved by or acceptable or satisfactory to such Bank unless an officer of the
Agent responsible for the transactions contemplated by the L/C Related
Documents shall have received notice from such Bank prior to the execution of
this Agreement by the Agent or prior to an amendment of the Letter of Credit,
as appropriate, specifying its objection thereto and either such objection
shall not have been withdrawn by notice to the Agent to that effect.

     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 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 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 L/C 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.


                                       62
<PAGE>   69
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.  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 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 the any such person
any way relating to or arising out of this Agreement 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 L/C 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 business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent or the Issuing
Bank hereunder and without notice to the Banks.  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 or the Issuing


                                       63
<PAGE>   70
Bank, 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
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)    In the event that the Banks obtain any collateral for the
Obligations, 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 L/C Related Document; (ii) constituting Property sold or to be sold
or disposed of as part of or in connection with any disposition permitted
hereunder; (iii) constituting Property 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 Property 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 all the Banks as


                                       64
<PAGE>   71
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).

          (c)    Each Bank agrees with and in favor of each other (which
agreement shall not be for the benefit of the Company, the Guarantor, or any of
the Guarantor's Subsidiaries) that the Company's obligation to such Bank under
this Agreement and the other L/C Related Documents is not and shall not be
secured by any real property collateral now or hereafter acquired by such Bank.

                                 MISCELLANEOUS


     10.01       Amendments and Waivers.  No amendment or waiver of any 
provision of this Agreement or any other L/C Related Document and no consent 
with respect to any departure by the Company 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

          (g)    release the Guarantor from its obligations under Section 2 of
the Guaranty or any amendment of Section 2 of the Guaranty; or

          (h)    extend the termination date of the Letter of Credit beyond

Banks if so required by this Agreement, affect the rights or duties of the
Agent under this Agreement or any other L/C Related Document.

         10.02   Notices.

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

otherwise provides, telegraphic, telex, facsimile transmission or cable

          (b)    All such notices and communications shall, when transmitted by

          (c)    The Company acknowledges and agrees that the agreement of the
Agent and the Banks at Article II herein to receive certain notices by
telephone and facsimile is solely for the convenience and at the request of the
Company.  The Agent and the 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


                                       66
<PAGE>   73
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 L/C 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 any Bank or the Agent takes any action in
connection with the enforcement or preservation of any rights (including in
connection with any "workout" or restructuring regarding the Letter of Credit,
this Agreement, or any L/C Related Document), pay or reimburse each Bank and
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 "workout" or restructuring regarding the Letter of Credit, this
Agreement, or any L/C Related Document) under this Agreement, any L/C 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 to each of the Banks;

but, in


                                       67
<PAGE>   74
the case of an appraisal, only to the extent it was reasonable to obtain such
appraisal; and

          (d)    pay to the Agent all fees required by letter agreement between
the Agent and the Company or the Guarantor to be paid whether or not any of the
transactions contemplated by this Agreement are consummated.

     10.05       Indemnity.  The Company shall pay, indemnify, and hold each
Bank, the Agent and each of their respective officers, directors, employees,
counsel, agents and attorneys-in-fact (each, an "Indemnified Person") harmless
from and against any and all liabilities, obligations, losses, damages,
penalties, 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 of this Agreement and any
other L/C Related Documents or the transactions contemplated herein, and with
respect to any investigation, litigation or proceeding related to this
Agreement or the Letter of Credit or the use 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
Proceeding, or otherwise, then to the extent of such recovery the obligation or
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

prior written consent of each Bank.

     10.08   Assignments, Participations, etc.

          (a)    Any Bank may, with the written consent of (i) the Company (at
all times other than during the existence of an Event of Default), (ii) the
Agent, and (iii) the Issuing Bank, which consent of the Company shall not be
unreasonably withheld, at any time assign and delegate to one or more Eligible
Assignees (provided that no written consent of the Company or the Agent or the
Issuing Bank 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 and the other rights and obligations of
such Bank hereunder, in a minimum amount of $5,000,000; provided, however,
that (i) the Company, the Agent, and the Issuing Bank 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 10.08
(an "Assignment and Acceptance").

          (b)    From and after the date that the Agent notifies the assignor
Bank that it has received an executed Assignment and Acceptance and payment of
the processing fee, (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 L/C 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, relinquish its
rights and be released from its obligations under the L/C Related Documents.

          (c)    Immediately upon each Assignee's 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 Commitments 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 Letter of Credit and the
drawings thereunder, the Commitment of that Bank and the other interests of
that Bank (the "originating Bank") hereunder and under the other L/C Related
Documents; provided, however, that (i) the originating Bank's obligations under
this Agreement shall remain unchanged,


                                       69
<PAGE>   76
(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
L/C 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 L/C 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 L/C 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 L/C 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 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; and (D) to such Bank's
independent auditors and other professional advisors.  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 Agent or the Banks
pursuant to this Agreement or which has been


                                       70
<PAGE>   77
delivered to the Agent or the Banks by the Company in connection with the
Banks' credit evaluation of the Company prior to entering into this Agreement;
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.  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 L/C Related Document irrespective of whether or not the Agent or
such Bank shall have made demand under this Agreement or any L/C 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.

     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 Domestic 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 or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

Agreement and each of the other L/C Related Documents.

                                  Exhibit 2.14

                                    Guaranty        Morrison Knudsen Corporation

         This Guaranty is entered into as of August 4, 1992, between MORRISON
KNUDSEN CORPORATION, a Delaware corporation (the "Guarantor"), and Bank of
America National Trust and Savings Association as agent (in such capacity, the
"Agent") for the banks (collectively "Banks" and individually "Bank") party to
the Standby Letter of Credit and Reimbursement Agreement referred to below.

                                   Recitals.

         A.      Morrison Knudsen Corporation, an Ohio corporation (the
"Borrower"), the Banks, and the Agent entered into a Standby Letter of Credit
and Reimbursement Agreement dated as of August 4, 1992.  The Standby Letter of
Credit and Reimbursement Agreement as now in effect or hereafter extended,
renewed or amended is hereinafter called the "Reimbursement Agreement".

         B.      The Banks are willing to make a letter of credit available to
the Borrower as provided in the Reimbursement Agreement on the condition that
all of the Borrower's indebtedness and obligations under the Reimbursement
Agreement are guaranteed by Guarantor.

         C.      In order to induce the Banks to make said letter of credit
available to the Borrower as provided in the Reimbursement Agreement, and for
other valuable consideration, the Guarantor issues this Guaranty of the
Borrower's indebtedness and obligations under the Reimbursement Agreement.

1.       Definitions.

         Unless otherwise defined herein, capitalized terms used in this
Guaranty have the meanings given to them in the Reimbursement Agreement.

2.       Guaranty.

         2.1     Guaranty.     The Guarantor hereby unconditionally guarantees
and  promises to pay to the Agent and each Bank, or order, on demand, any and
all indebtedness and obligations of the Borrower to the Agent and each Bank
from time to time outstanding under or in respect to the Reimbursement
Agreement (the "Obligations").  The Agent, the Banks or any Bank may permit the
indebtedness of the Borrower to the Agent, the Banks or any Bank to include
indebtedness other than the Obligations, and may apply any


                                       1
<PAGE>   98
amounts received from any source, other than from the Guarantor, to that
portion of Borrower's indebtedness to the Agent, the Banks, or any Bank, which
is not a part of the Obligations.

         2.2     Obligations Independent.  The obligations hereunder are joint
and several, and independent of the obligations of the Borrower, and a separate
action or actions may be brought and prosecuted against the Guarantor whether
action is brought against the Borrower or whether the Borrower be joined in any
such action or actions.   The Guarantor waives the benefit of any statute of
limitations affecting its liability hereunder.

         2.3     Authorization of Renewals, Etc.      The Guarantor authorizes
the Agent and each Bank, without notice or demand and without affecting its
liability hereunder, from time to time to:

                 (a)      renew, compromise, extend, accelerate or otherwise
change the time for payment, or otherwise change the terms, of the Obligations,
including increase or decrease of the rate of interest thereon, or otherwise
change the terms of the Reimbursement Agreement;

                 (b)      receive and hold security for the payment of this
Guaranty or the Obligations and exchange, enforce, waive, release, fail to
perfect, sell, or otherwise dispose of any such security;

                 (c)      apply such security and direct the order or manner of
sale thereof as the Agent, the Banks or any Bank, as the case may be, in its or
their discretion may determine; and

                 (d)      release or substitute any one or more of any
endorsers or guarantors of the Obligations.

The performance or occurrence of any of the acts or events described in clauses
(a), (b), (c), and (d) above with respect to indebtedness of the Borrower,
other than the Obligations, to the Agent, the Banks, or any Bank, shall not
affect the liability of the Guarantor hereunder.

         2.4     Waiver of Certain Rights.  The Guarantor waives any right to
require the Agent or any Bank to:

                 (a)      proceed against the Borrower;

                 (b)      proceed against or exhaust any security for the
         Obligations or any other indebtedness of the Borrower to the Agent,
         the Banks, or any Bank; or


                                       2
<PAGE>   99
                 (c)      pursue any other remedy in the Agent's or any such
         Bank's power whatsoever.

         2.5     Waiver of Certain Defenses.  The Guarantor waives any defense
arising by reason of any disability or other defense of the Borrower, or the
cessation from any cause whatsoever of the liability of the Borrower, or any
claim that the Guarantor's obligations exceed or are more burdensome than those
of the Borrower.

         2.6     Waiver of Subrogation.    The Guarantor waives any right of
subrogation, reimbursement, indemnification, and contribution (contractual,
statutory or otherwise), including without limitation, any claim or right of
subrogation under the Bankruptcy Code (Title 11 of the U.S. Code) or any
successor statute, against the Borrower arising from the existence or
performance of this Guaranty and the Guarantor waives any right to enforce any
remedy which the Agent, the Banks or any Bank now has or may hereafter have
against the Borrower, and waives any benefit of, and any right to participate
in, any security now or hereafter held by the Agent, the Banks or any Bank
securing the Obligations.  The Agent, the Banks or any Bank may foreclose,
either by judicial foreclosure or by exercise of power of sale, any deed of
trust or mortgage securing the Obligations or any other indebtedness of the
Borrower to the Agent, the Banks or any Bank, and, even if the foreclosure may
destroy or diminish the Guarantor's rights against the Borrower, the Guarantor
shall be liable to the Agent and each Bank for any part of the Obligations
remaining unpaid after the foreclosure.

         2.7     Waiver of Presentments, Etc.  The Guarantor waives all
presentments, demands for performance, notices of nonperformance, protests,
notices of protest, notices of dishonor, and notices of acceptance of this
Guaranty and of the existence, creation, or incurring of new or additional
Obligations or any other indebtedness of Borrower to the Agent, the Banks or
any Bank.

         2.8     Information Relating to Borrower.     The Guarantor
acknowledges and agrees that it shall have the sole responsibility for
obtaining from the Borrower such information concerning the Borrower's
financial condition or business operations as the Guarantor may require, and
that neither the Agent nor any Bank has any duty at any time to disclose to the
Guarantor any information relating to the business operations or financial
condition of the Borrower.

         2.9     Right of Setoff.    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
Guarantor, any such notice being waived


                                       3
<PAGE>   100
by the Guarantor 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 Guarantor against any and all obligations
of the Guarantor now or hereafter existing under this Guaranty or any other L/C
Related Document, irrespective of whether or not the Agent or such Bank shall
have made demand under this Guaranty or any L/C Related Document and although
such obligations may be contingent or unmatured.  Each Bank agrees promptly to
notify the Guarantor 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 2.9 are in addition to the other rights and remedies
(including without limitation, other rights of set-off) which such Bank may
have.

         2.10    Subordination.  Any obligations of the Borrower to the
Guarantor, now or hereafter existing, including but not limited to any
obligations to the Guarantor as subrogee of the Agent, the Banks or any Bank
or resulting from the Guarantor's performance under this Guaranty, are hereby
subordinated to the Obligations and all other indebtedness of the Borrower to
the Agent, the Banks, or any Bank.  Such obligations of the Borrower to the
Guarantor if the Majority Banks so request shall be enforced and performance
received by the Guarantor as trustee for the Agent and the Banks and the
proceeds thereof shall be paid over to the Agent and the Banks on account of
the Obligations, but without reducing or affecting in any manner the liability
of the Guarantor under the other provisions of this Guaranty.

         2.11    Reinstatement of Guaranty.     If this Guaranty is returned or
canceled, and subsequently any payment or transfer of any interest in property
by the Borrower to the Agent or any Bank in fulfillment of any Obligation is
rescinded or must be returned by the Agent or any Bank to the Borrower, this
Guaranty shall be reinstated with respect to any such payment or transfer,
regardless of any such prior return or cancellation.

         2.12    Powers.  It is not necessary for the Agent or any Bank to
inquire into the powers of the Borrower or of the officers, directors, partners
or agents acting or purporting to act on its behalf, and any Obligations made
or created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder.

         2.13     Taxes.   (a) (i) If any taxes (other than taxes on net income
(A) imposed by the country or any subdivision of the country in which a Bank's
principal office or actual lending office is located and (B) measured by the
United States taxable income such Bank would have received if such Bank's share
in all payments


                                       4
<PAGE>   101
under or in respect of this Guaranty and any instrument or agreement required
from the Guarantor under the Reimbursement Agreement were exempt from taxes
levied by the Guarantor's country) are at any time imposed on such Bank's
share in any payments made under or in respect of this Guaranty and any
instrument or agreement required from the Guarantor under the Reimbursement
Agreement including, but not limited to, payments made pursuant to this
Section, the Guarantor shall pay all such taxes and shall also pay to such
Bank, on demand, all additional amounts which such Bank specifies as necessary
to preserve the after-tax yield such Bank would have received if such taxes had
not been imposed.

          (ii)   The additional amounts necessary to preserve the after-tax
yield such Bank would have received if such taxes had not been imposed shall be
calculated pursuant to the formula:

                                                 (w) (t) (i)
                                           y =  -------------
                                                    1-w-t

         where the terms are defined as follows:

                 y =  additional payment to be made to the Bank 
                 w =  withholding tax rate levied by foreign government

                 t =  the Bank's combined Federal and state tax rate

                 i =  stated interest to be paid on Obligations (base rate plus
                      quoted spread, all multiplied by the amount of such
                      Obligations)

                 1 =  one

                 (b)      The  Guarantor will provide such Bank with original
tax receipts, notarized copies of tax receipts, or such other documentation as
will prove payment of tax in a court of law applying the United States Federal
Rules of Evidence, for all taxes paid by the Guarantor pursuant to subparagraph
(a) above. The Guarantor will deliver receipts to such Bank within 30 days
after the due date for the related tax.

         3.6     No Default.   No Default or Event of Default exists or would
result from the incurring of obligations by the Guarantor under this Guaranty
or any other L/C Related Document.  Neither the Guarantor nor any of its

employment with the Borrower or the Guarantor, except to the extent required
by Section 4980B of the Code and at the sole expense of the participant or the
beneficiary of the participant to the fullest extent permissible under such

respects with the notice and continuation coverage requirements of Section

such liability) under Section 4201 or 4243 of ERISA with respect to a
Multiemployer Plan or (ii) any liability under Title IV of ERISA (other than

the Guarantor or any of its Subsidiaries of the Contract or any other documents
and agreements related thereto.

                 (c)      The Contract and the other documents and agreements
related thereto to which the Borrower, the Guarantor or any of their respective

Subsidiary than would obtain in a comparable arm's-length transaction with a
Person not an Affiliate of the Guarantor.

not result, in the aggregate for all Plans, in a Material Adverse Effect, the
Guarantor shall not directly or indirectly and shall not permit or suffer any

Bank of America National Trust and
  Savings Association
315 Montgomery Street, 15th Floor
San Francisco, California 94104

Dear Sirs:

         We have acted as counsel for Morrison Knudsen Corporation, an Ohio
corporation (the "Company"), and Morrison Knudsen Corporation, a Delaware
corporation (the "Guarantor"), in connection with the execution and delivery of
the Standby Letter of Credit and Reimbursement Agreement, dated as of ________
________, 1992 (the "Agreement"), between the Company, the several financial
institutions party thereto (collectively, the "Banks"), and Bank of America
National Trust and Savings Association, as agent for the Banks (the "Agent").

         This opinion is provided to the Bank as required pursuant to Section
4.01 of the Agreement.  Capitalized terms not otherwise defined herein have
the respective meanings set forth in the Agreement.

         We have examined executed copies of the Agreement, the Guaranty, the
Letter of Credit, and the various other L/C Related Documents, certificates of
public officials from the States of Ohio and Delaware, the certificates of
incorporation and by-laws of the Company and the Guarantor, in each case, as
amended to date; records of proceedings of the Boards of Directors of the
Company and the Guarantor during or by which resolutions were adopted relating
to matters covered by this opinion, and certificates of officers of the
Company as to certain factual matters.  In addition, we have made such other
investigations as we have deemed necessary to enable us to express the opinions
hereinafter set forth.  We have assumed the genuineness of all signatures of
persons signing the Agreement and the Guaranty on behalf of parties thereto
other than the Company and the Guarantor, the authenticity of all documents
submitted to us as originals and the conformity to authentic original documents
of all documents submitted to us as certified, conformed or photostatic copies.
We have further assumed (i) the due organization, valid existence, and good
standing under its jurisdiction of organization of each party to the L/C
Related Documents (other than the Company or the Guarantor), and the
enforceability of each L/C Related Document





                                     - 1 -
<PAGE>   124
against each party thereto (other than the Company or the Guarantor), and (iii)
the power and authority of each party to an L/C Related Document (other than
the Company or the Guarantor) to enter into and perform its respective
obligations under each L/C Related Document to which it is a party.

         As to any facts material to this opinion which we did not
independently establish or verify, we have relied upon representations of
officers and other representatives of the Company and the Guarantor and others,
and we believe such reliance is justified.

         Attorneys in this office are members of the Bars of the States of
California and Idaho, and we do not express any opinion herein concerning any
other law, other than the federal law of the United States the corporation law
of the State of Ohio as it relates to the opinions set forth below, and the
Delaware General Corporation Law.

         Based upon the foregoing, and further subject to the last two
paragraphs of this letter, we hereby advise you that in our opinion:

         1.      (a)   The Company has been duly incorporated and is validly
         existing and in good standing as a corporation under the laws of the
         State of Ohio.

                 (b)      The Guarantor has been duly incorporated and is
         validly existing and in good standing as a corporation under the laws
         of the State of Delaware.

                 (c)      Each Subsidiary of the Guarantor is duly organized
         and existing under the laws of the jurisdiction of its formation.

         2.      (a) The Company has the corporate power and authority to own
         its assets, to conduct the business in which it is currently engaged,
         and to execute, deliver, and perform the Agreement and to execute the
         other L/C Related Documents to which it is a party.

                 (b)      The Guarantor has the corporate power and authority
         to own its assets, to conduct the business in which it is currently
         engaged and to execute, deliver, and perform under, the Guaranty and
         to execute other L/C Related Documents to which it is a party.

         3.      (a)   Each of the Company and the Guarantor is duly qualified
         as a foreign corporation and in good standing under the laws of each
         jurisdiction where its ownership, lease, or operation of property or
         the conduct of its business requires such qualification, except to the
         extent that the failure to be so qualified would not, in the
         aggregate, have a Material Adverse Effect.

                 (b)      Each Subsidiary of the Guarantor is duly qualified as
         a foreign corporation and in good standing under the laws of each
         jurisdiction where its ownership, lease, or operation of property or
         the conduct of its business requires such qualification, except to the
         extent that the failure to be so qualified would not, in the aggregate
         over all Subsidiaries of the Guarantor, have a Material Adverse
         Effect.

         4.      (a)   The Agreement and the Letter of Credit have been duly
         authorized by the Company and no further corporate action is required
         in connection therewith.  The execution and delivery of the Agreement
         and the due performance of the provisions therein do not and will not

         incorporation, by-laws or any agreement, indenture, or other document
         or instrument or Contractual Obligation to which the Company is a
         party or by the terms by which the Company or any of its property is

         to any Contractual obligation.

         Guarantor and no further corporate action is required in connection
         therewith.  The execution and delivery of the Guaranty and the due
         performance of the provisions therein do not and will not violate,

         incorporation, by-laws or any agreement, indenture, or other document
         or instrument or Contractual Obligation to which the Guarantor is a
         party or by the terms by which the Guarantor or any of its property
         is bound or affected, or result in or require the creation  or
         imposition of any Lien on any of the respective properties  or
         revenues of the Company or the Guarantor or any subsidiary  of the
         Guarantor pursuant to any Contractual Obligation.

         5.      (a)      Except as set forth on Schedule 5.05 of of the
         Agreement, no litigation, investigation, or proceedings of or before
         any court, arbitrator, or other Governmental Authority is pending or,
         to the best of our knowledge, threatened, against the Company, the
         Guarantor, or any subsidiary of the Guarantor or any of their
         respective properties or revenues, which, if determined adversely to
         the Company, the Guarantor, or any Subsidiary of the Guarantor, could
         reasonably be expected to have a Material Adverse Effect.

                 (b)      Except as set forth on Schedule 5.12 of the
         Agreement, no litigation, investigation, claims, disputes, or other

         result in liabilities in excess of $10,000,000 in the aggregate.

         Guarantor, or any Subsidiary of the Guarantor, which purports to
         affect or pertain to the Contract.

         6.      Neither the Company, the Guarantor, nor any Subsidiary of the
         Guarantor is an "investment company", or a company "controlled" by an
         "investment company", within the meaning of the Investment Company Act
         of 1940, as amended.

         7.      Regulation U of the Board of Governors of the Federal Reserve
         System does not apply to the Company's procurement of the issuance of
         the Letter of Credit for the account of the Company, any extension of
         credit under the Agreement, or any of the obligations of the Company
         or the Guarantor under the Agreement or the Guaranty.

         8.      Except as set forth on Schedule 5.12 of the Agreement, the
         Company, the Guarantor, and each Subsidiary of the Guarantor are in
         compliance with all Environmental Laws, except such non-compliance
         which would not result in liability in excess of $10,000,000 in the
         aggregate.

         9.      To the best of our knowledge, no event has occurred or would
         result from the incurring of the obligations by the Company under the
         Agreement or by the Guarantor under the Guaranty which is, or with the
         lapse of time or notice or both would become, an Event of Default.

         10.     The Guarantor has no Subsidiaries other than those listed on
         Schedule 5.18(a) of the Agreement.

         This letter has been furnished to you pursuant to Article IV of the
Agreement for your use in connection with the Agreement, and except for
reliance upon by the Agent, the Banks, and Participants and Assignees, may not
be relied upon for any other purpose or by any other party without our consent.

                               Very truly yours,

                                  Re:  Standby Letter of Credit

         Dear Sirs:

                We have acted as special California counsel to Morrison Knudsen
         Corporation, an Ohio corporation (the "Company"), and Morrison Knudsen
         Corporation, a Delaware corporation (the "Guarantor"), in connection
         with the transactions contemplated by the Standby Letter of Credit and
         Reimbursement Agreement, dated as of _________________ ____,  1992 (the
         "Agreement"), among the Company, the several financial institutions
         party thereto (collectively, the "Banks"), and Bank of America
         National Trust and Savings Association, as agent for the Banks (the
         "Agent").  This opinion is provided to the Agent as required pursuant
         to Section 4.01(e) of the Agreement.  Capitalized terms not otherwise
         defined herein have the respective meanings set forth in the
         Agreement.

                For the purposes of this opinion, we have examined original
         counterparts, or copies certified or otherwise identified to our
         satisfaction, of the Agreement, the Guaranty, the Letter of Credit,
         the Assignment and Acceptance in the form of Exhibit 10.08 to the
         Agreement and the pledge and security agreement in the form of Exhibit
         2.07 to the Agreement (collectively, the "Loan Documents").  We have
         also examined and relied upon the originals, or copies certified or
         otherwise identified to our satisfaction, of certificates of public
         officials from the States of Ohio and Delaware, the certificates of
         incorporation and by-laws of the Company and the Guarantor, in each
         case, as amended to date; records of proceedings of the Boards of
         Directors of the Company and the Guarantor during or by which
         resolutions were adopted relating to matters covered by this opinion,
         and certificates of officers of the Company as to certain factual
         matters.  In addition, we have examined such other documents,
         records, and matters of law and made such other investigations as we
<PAGE>   128
To the Parties Listed on
   the Attached Schedule A
Re: Standby Letter of Credit
August 3, 1992
Page 2

         have deemed necessary for the purposes of the opinion
         hereinafter set forth.

                For the purposes of this opinion, we have assumed (a) that
         (except as to the Company and the Guarantor) all of the documents
         referred to in this opinion have been duly authorized, executed and
         delivered by, and that lawful consideration has been provided by all
         of the parties to such documents, (b) that all of the signatures and
         acknowledgements by or on behalf of all of the parties so such
         documents are genuine, (c) that (except as to the Company and the
         Guarantor) all signatories to such documents have been authorized, (d)
         that all such parties are duly organized and validly existing and have
         the power and authority to execute, deliver and perform such
         documents, (e) that all of the documents submitted to us as executed
         counterparts are authentic and (f) that all of the documents submitted
         to us as copies conform to the executed counterparts of such
         documents.  As to any facts material to this opinion which we did not
         independently establish or verify, we have relied upon representations
         of officers and other representatives of the Company and the Guarantor
         and others and we believe it is reasonable to rely upon such
         representations.

                We have further assumed, without independent investigation or
         inquiry, that each Bank is a bank organized or incorporated under, or
         a foreign bank licensed to conduct a banking business through an
         agency or branch located in the United States of America pursuant to,
         the laws of the United States of America or any state of the United
         States of America within the meaning of Section 1 of Article XV of the
         California Constitution and Section 1716 of the California Financial
         Code, and we express no opinion as to whether or not any Bank falls
         within such meanings.

                Based upon the foregoing, and further subject to the
         assumptions, qualifications, explanations and limitations set forth
         herein, we are of the opinion that:

         1.   (a)  Each of the Agreement and the other Loan Documents to which
         the Company is a party constitutes,
<PAGE>   129
To the Parties Listed on
   the Attached Schedule A
Re: Standby Letter of Credit
August 3, 1992
Page 3

         or when delivered will constitute, the valid and binding obligations
         of the Company, enforceable against the Company in accordance with
         their terms.

                 (b)      Each of the Guaranty and the other Loan Documents to
         which the Guarantor is a party constitutes, or when delivered will
         constitute, the valid and binding obligations of the Guarantor,
         enforceable against the Guarantor in accordance with their terms.

         2.      No consent, approval, authorization, registration, or filing
         with any Governmental Authority is required on the part of the Company
         or the Guarantor in connection with the execution, delivery or
         performance of the Agreement, the Guaranty, or the other Loan
         Documents, except as may have been obtained and certified copies of
         which have been delivered to by the Guarantor and the Company to the
         Agent.

         3.      The execution, delivery, and performance by the Company and
         the Guarantor of the Agreement, the Guaranty, and the other Loan
         Documents to which the Company or the Guarantor is a party will not
         violate, contravene, or result in a breach of any Requirement of Law
         applicable to the Company or the Guarantor, or result in or require
         the creation or imposition of any Lien on any of its respective
         properties or revenues of the Company or the Guarantor or any
         Subsidiary of the Guarantor pursuant to such Requirement of Law,
         except for such violations, contraventions, breaches or Liens as would
         not, in the aggregate, have a Material Adverse Effect.

         The foregoing opinions are subject to the following assumptions,
qualifications, explanations and limitations:

                 (a)      The enforceability of the obligations of the Company
         and the Guarantor under, and the rights and remedies provided for in,
         the Loan Documents may be limited by bankruptcy, insolvency,
         reorganization, moratorium or similar laws relating to or affecting
<PAGE>   130
To the Parties Listed on

         creditors' rights generally and are subject to general principles of
         equity (whether considered in a proceeding in law or at equity),
         including without limitation (i) the possible unavailability of
         specific performance, injunctive relief or any other equitable remedy
         and (ii) concepts of materiality, reasonableness, good faith and fair
         dealing.

                 (b)      The enforceability of certain provisions of the Loan
         Documents may be limited by California laws rendering unenforceable
         (i) the release of a party from, or the indemnification of a party
         against liability for its own wrongful or negligent acts under certain
         circumstances or (ii) indemnification contrary to public policy.

                 (c)      The enforceability of certain provisions of the Loan
         Documents may be limited under certain circumstances to the extent
         that such provisions purport to impose invalid liquidated damages,
         penalties, forfeiture or late payment charges or a higher rate of
         interest as a result of delinquency in payment or the occurrence of a
         default.

                 (d)      The enforceability of certain provisions of the Loan
         Documents to the effect that the terms thereof may not be waived or
         modified except in writing, may be limited to the extent that a
         performed oral agreement has been created modifying any such document
         or that an implied agreement by trade practice or course of dealing
         has been created allowing a waiver.

                 (e)      The enforceability of certain provisions of the Loan
         Documents may be limited by provisions or judicial interpretations of
         California law relating to the enforcement of the rights of a secured
         creditor, which modify or affect the remedial provisions provided for,
         or which invalidate waivers (including, without limitation, any waiver
         of the protection of applicable statutes of limitation) set forth in,
         the Loan Documents, including limitations on the ability of a
<PAGE>   131

Page 5

         lender to exercise various self-help or summary remedies without
         notice or opportunity for hearing.

                 (f)      We also advise you of California statutory provisions
         and case law to the effect that, in certain circumstances, a surety
         may be exonerated if the creditor materially alters the original
         obligation of the principal without the consent of the guarantor,
         elects remedies for default that impair the subrogation rights of the
         guarantor against the principal, or otherwise takes any action without
         notifying the guarantor that materially prejudices the guarantor.

                All statements in this opinion which are limited to our current
         actual knowledge are based solely upon (i) our examination described
         in this opinion, (ii) inquiry of the attorneys in our Los Angeles,
         California offices who have performed services for the Company and the
         Guarantor in connection with the transactions contemplated by the Loan
         Documents and (iii) inquiry of officers of the Company and the
         Guarantor.

                We are members of the Bar of the State of California, and we do
         not express any opinion herein concerning the laws of any other
         jurisdiction except the Federal law of the United States, the
         corporation law of the State of Ohio, and the Delaware General
         Corporation Law.

                This letter has been furnished to you by us as counsel to the
         Borrower and the Guarantor pursuant to Section 4.01(e) of the
         Agreement for your use in connection with the Agreement, and except
         for reliance upon by the Banks, and Participants and Assignees, may
         not be relied upon for any other purpose or by any other party without
         our prior consent in each instance.

                                        Very truly yours,

                            Re:  opinion of Counsel

Dear Sirs:

         We have acted as counsel for Morrison Knudsen Corporation, an Ohio
corporation (the "Company"), and Morrison Knudsen Corporation, a Delaware
corporation (the "Guarantor"), in connection with the proceedings referenced in
our opinion below.

         Subject to the last two paragraphs of this letter, we hereby advise
you that in our opinion:

         1.      The proceedings brought by Local No. 719, United Auto Workers
and Carole J. Travis and Bombardier Corporation and Pullman Technology, Inc.
against Metra and Morrison Knudsen Corporation, which proceedings began in the
Circuit Court of Cook County, Illinois and had case numbers 92-CH-01041 and
92-CH-10142, and all related lawsuits, actions, litigation, and other
proceedings, whether at law or in equity, have been terminated by a judgment in
favor of the defendants, Metra and Morrison Knudsen Corporation, and all rights
to appeal have been extinguished.  Thus, the doctrine of res judicata would
preclude any subsequent action by Local 719, Ms. Travis, Bombardier or Pullman.

         We are members of the Bar of the State of Illinois and we do not
express any opinion herein concerning any law other than the law of the State
of Illinois.

         This letter has been furnished to you in connection with the execution
and delivery of the Standby Letter of Credit and Reimbursement Agreement, dated
as of           , 1992, (the "Agreement"), between the Company, the several

         THIS WAIVER TO STANDBY LETTER OF CREDIT AND REIMBURSEMENT AGREEMENT
(the "Waiver"), dated as of March 31, 1994, is entered into by and among
Morrison Knudsen Corporation, an Ohio corporation (the "Company"), BANK OF
AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION, as agent for itself and the
Banks (the "Agent"), and the several financial institutions party to the Credit
Agreement (collectively, the "Banks").


                                    RECITALS

         A.      The Company, Banks, and Agent are parties to a Standby Letter
of Credit and Reimbursement Agreement dated as of August 4, 1992 as amended by
that Waiver and Amendment to Credit Agreement dated as of December 22, 1992 and
as further modified by that Waiver to Standby Letter of Credit and
Reimbursement Agreement dated as of August 6, 1993 (as so amended and modified,
the "Credit Acrreement") pursuant to which the Agent and the Banks have
extended certain credit facilities to the Company and certain of its
subsidiaries and pursuant to which the Issuing Bank has issued a letter of
credit for the benefit of Metra and for the account of the Company.

         B.      The Company proposes to consolidate within its wholly-owned
subsidiary, MK Rail Corporation, a Delaware corporation ("MK Rail"), the
business of the remanufacture of locomotives, the manufacture of new
locomotives, the design, manufacture and distribution of locomotive component
parts and the provision of locomotive fleet maintenance services (together, the
"Business"), which heretofore has been conducted through various divisions and
subsidiaries of the Company.  In connection therewith, the Company will
transfer certain assets relating to the Business to MK Rail, enter into an
Environment Liability Transfer Agreement pursuant to which MK Rail will assume
all environmental liabilities and obligations relating to the Business,
transfer certain obligations to MK Rail and enter into other arrangements, all
as described in that Form S-1 Registration Statement filed by MK Rail with the
SEC on February 24, 1994 (the "S-1").  Coincident with such transactions, MK
Rail proposes to conduct an initial public offering of eight million shares of
its common stock, as more specifically described in the S-1 (the "Offering").

         C.      The Company has requested that the Banks (i) consent to the
transfer of property and obligations relating to the Business to MK Rail as
described in the S-1 (the "Transfer"), (ii) consent to the Offering, and (iii)
waive the potential non-compliance with certain existing covenants under the
Credit Agreement in connection with the Transfer and the Offering.


                                       1
<PAGE>   168
         D.      The Agent and the Banks are willing to consent to and waive
compliance with certain matters for purposes of the Credit Agreement, subject
to the terms and conditions of this Waiver.

         NOW, THEREFORE, for valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto hereby agree as follows:

         1.      Defined Terms.  Unless otherwise defined herein, capitalized
terms used herein shall have the meanings, if any, assigned to them in the
Credit Agreement.

         2       Waiver.

                 (a)      For purposes of this Waiver, the "Items of Non-
Compliance" shall mean:

                          (i)     any non-compliance with the requirements of
         Section 7.02 of the Credit Agreement solely as a consequence of the
         Transfer or the Offering; and

                          (ii)    any non-compliance with the requirements of
         Section 7.03 of the Credit Agreement solely as a consequence of the
         Transfer or the offering.

                 (b)      Subject to and upon the terms and conditions hereof,
the Agent and the Banks hereby waive the non-compliance constituting the Items
of Non-Compliance, providing the Transfer and Offering are consummated no later
than June 30, 1994.

                 (c)      The Items of Non-Compliance are prospective only; the
Company represents below that there exists no Default or Event of Default.
Nothing contained herein shall be deemed a waiver of (or otherwise affect
the Agent's or the Banks' ability to enforce) any Default or Event of Default,
including without limitation (i) any Default or Event of Default as may now or
hereafter exist and arise from or otherwise be related to the Transfer or the
Offering (including without limitation any cross-default arising under the
Credit Agreement by virtue of any matters resulting from the Transfer or the
Offering), and (ii) any Default or Event of Default arising at any time after
the Effective Date and which is the same as any of the Items of Non-Compliance.

         3.      Representations and Warranties.  The Company hereby represents
and warrants to the Agent and the Banks as follows:

                 (a)      No Default or Event of Default has occurred and is
continuing.

                 (b)      The execution, delivery and performance by the
Company of this Waiver have been duly authorized by all necessary corporate and
other action and do not and will not require any


                                       2
<PAGE>   169
registration with, consent or approval of, notice to or action by, any Person
(including any Governmental Authority) in order to be effective and
enforceable.  The Credit Agreement constitutes the legal, valid and binding
obligations of the Company, enforceable against it in accordance with its
respective terms, without defense, counterclaim or offset.

                 (c)      All representations and warranties of the Company
contained in the Credit Agreement are true and correct.

                 (d)      The Company is entering into this Waiver on the basis
of its own investigation and for its own reasons, without reliance upon the
Agent and the Banks or any other Person.

         4.      Effective Date.  This Waiver will become effective as of March
31, 1994 (the "Effective Date"), provided that each of the following conditions
precedent has been satisfied:

                 (a)      The Agent has received from the Company and the
Majority Banks a duly executed original or facsimile copy of this Waiver,
together with a Waiver to Guaranty ("Guaranty Waiver") addressing matters
relating to the subject of this Waiver, duly executed by the Guarantor and the
Majority Banks.  The Agent may rely upon any document delivered to it in
legible form by facsimile transmission.

                 (b)      The Agent has received from the Company and the
Guarantor a copy of a resolution passed by the board of directors of each such
corporation, certified by the Secretary or an Assistant Secretary of such
corporation as being in full force and effect on the date hereof, authorizing
the execution, delivery and performance of this Waiver and the Guaranty Waiver,
respectively.

                 (c)      All representations and warranties contained herein
are true and correct as of the Effective Date.

         5.      Reservation of Rights.  The Company acknowledges and agrees
that neither the Agent's nor the Banks' execution and delivery of this Waiver,
shall be deemed (i) to create a course of dealing or otherwise obligate the
Agent or the Banks to forbear or execute similar waivers under the same or
similar circumstances in the future, or (ii) to waive, relinquish or impair
any right of the Agent or the Banks to receive any indemnity or similar payment
from any person or entity as a result of any matter arising from or relating to
the Transfer or the Offering.

         6.      Miscellaneous.

                 (a)      Except as herein expressly amended, all terms,
covenants and provisions of the Credit Agreement are and shall remain in full
force and effect and all references therein to


                                       3
<PAGE>   170
such Credit Agreement shall henceforth refer to the Credit Agreement as amended
by this Waiver.  This Waiver shall be deemed incorporated into, and a part of,
the Credit Agreement.

                 (b)      This Waiver shall be binding upon and inure to the
benefit of the parties hereto and thereto and their respective successors and
assigns.  No third party beneficiaries are intended in connection with this
Waiver.

                 (c)      This Waiver shall be governed by and construed in
accordance with the law of the State of California.

                 (d)      This Waiver may be executed in any number of
counterparts, each of which shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument.

                 (e)      This Waiver, together with the Credit Agreement,
contains the entire and exclusive agreement of the parties hereto with
reference to the matters discussed herein and therein.  This Waiver supersedes
all prior drafts and communications with respect thereto.  This Waiver may not
be amended except in accordance with the provisions of Section 10.01 of the
Credit Agreement.

                 (f)      If any term or provision of this Waiver shall be
deemed prohibited by or invalid under any applicable law, such provision shall
be invalidated without affecting the remaining provisions of this Waiver or the
Credit Agreement, respectively.

                 (g)      The Company covenants to pay to or reimburse the
Agent, upon demand, for all costs and expenses (including allocated costs of
in-house counsel) incurred by the Agent in connection with the development,
preparation, negotiation, execution and delivery of this Waiver and the
Guaranty Waiver.

         IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Waiver as of the date first above written.

                               WAIVER TO GUARANTY

         THIS WAIVER TO GUARANTY (the "Waiver"), dated as of March 31, 1994, is
entered into by and among, Morrison Knudsen Corporation, a Delaware corporation
(the "Guarantor"), BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION, as
agent for itself and the Banks (the "Agent"), and the several financial
institutions party to the Credit Agreement (collectively, the "Banks").

                                    RECITALS

         A.      Morrison Knudsen Corporation, an Ohio corporation (the
"Company"), Banks, and Agent are parties to a Standby Letter of Credit and
Reimbursement Agreement dated as of August 4, 1992 as amended by that Waiver
and Amendment to Credit Agreement dated as of December 22, 1992 and as further
modified by that Waiver to Standby Letter of Credit and Reimbursement Agreement
dated as of August 6, 1993 (as so amended and modified, the "Credit
Agreement") pursuant to which the Agent and the Banks have extended certain
credit facilities to the Company and certain of its subsidiaries and pursuant
to which the Issuing Bank has issued a letter of credit for the benefit of
Metra and for the account of the Company.  The obligations of the Company under
the Credit Agreement are unconditionally guaranteed by the Guarantor pursuant
to that Guaranty dated as of August 4, 1992, as amended or modified by the
Waiver and Amendment to Guaranty dated as of December 22, 1992 and that Waiver
to Guaranty dated as of August 6, 1993 (as so amended and modified, the
"Guaranty").

         B.      The Company proposes to consolidate within its wholly-owned
subsidiary, MK Rail Corporation, a Delaware corporation ("IMK Rail"), the
business of the remanufacture of locomotives, the manufacture of new
locomotives, the design, manufacture and distribution of locomotive component
parts and the provision of locomotive fleet maintenance services (together, the
"Business"), which heretofore has been conducted through various divisions and
subsidiaries of the Company.  In connection therewith, the Company will
transfer certain assets relating to the Business to MK Rail, enter into an
Environment Liability Transfer Agreement pursuant to which MK Rail will assume
all environmental liabilities and obligations relating to the Business,
transfer certain obligations to MK Rail and enter into other arrangements, all
as described in that Form S-1 Registration Statement filed by MK Rail with the
SEC on February 24, 1994 (the "S-1").  Coincident with such transactions, MK
Rail proposes to conduct an initial public offering of eight million shares of
its common stock, as more specifically described in the S-1 (the "Offering").


                                       1
<PAGE>   188
         C.      The Company and the Guarantor have requested that the Banks
(i) consent to the transfer of property and obligations relating to the
Business to MK Rail as described in the S-1 (the "Transfer"), (ii) consent to
the Offering, and (iii) waive the potential non-compliance with certain
existing covenants under the Credit Agreement and the Guaranty in connection
with the Transfer and the Offering.

         D.      The Agent and the Banks are willing to consent to and waive
compliance with certain matters for purposes of the Guaranty, subject to the
terms and conditions of this Waiver.

         NOW, THEREFORE, for valuable consideration, the receipt and adequacy 
of which are hereby acknowledged, the parties hereto hereby agree as follows:

         1.      Defined Terms.  Unless otherwise defined herein, capitalized
terms used herein shall have the meanings, if any, assigned to them in the
Credit Agreement.

         2.       Waiver.

                 (a)      For purposes of this Waiver, the "Items of Non-
Compliance" shall mean:

                          (i)     any non-compliance with the requirements of 
         Section 5.2 of the Guaranty solely as a consequence of the Transfer
         or the Offering; and

                          (ii)    any non-compliance with the requirements of
         Section 5.3 of the Guaranty solely as a consequence of the Transfer or
         the Offering.

                 (b)       Subject to and upon the terms and conditions hereof,
the Agent and the Banks hereby waive the non-compliance constituting the Items
of Non-Compliance, providing the Transfer and Offering are consummated no later
than June 30, 1994.

                 (c)      The Items of Non-Compliance are prospective only; the
Guarantor represents below that there exists no breach of or default under the
Guaranty.  Nothing contained herein shall be deemed a waiver of (or otherwise
affect the Agent's or the Banks' ability to enforce) any Default or Event of
Default, including without limitation (i) any Default or Event of Default as
may now or hereafter exist and arise from or otherwise be related to the
Transfer or the Offering (including without limitation any cross-default
arising under the Credit Agreement by virtue of any matters resulting from the
Transfer or the Offering), and (ii) any Default or Event of Default arising at
any time after the Effective Date and which is the same as any of the Items of
Non-Compliance.


                                       2
<PAGE>   189
         3.      Representations and Warranties.  The Guarantor hereby
represents and warrants to the Agent and the Banks as follows:

                 (a)       No breach or default has occurred and is continuing
under the Guaranty.

                 (b)      The execution, delivery and performance by the
Guarantor of this Waiver have been duly authorized by all necessary corporate
and other action and do not and will not require any registration with, consent
or approval of, notice to or action by, any Person (including any Governmental
Authority) in order to be effective and enforceable.  The Guaranty constitutes
the legal, valid and binding obligations of the Guarantor, enforceable against
it in accordance with its respective terms, without defense, counterclaim or
offset.

                 (c)      All representations and warranties of the Guarantor
contained in the Guaranty are true and correct.

                 (d)      The Guarantor is entering into this Waiver on the
basis of its own investigation and for its own reasons, without reliance upon
the Agent and the Banks or any other Person.

         4.      Effective Date.  This Waiver will become effective as of March

precedent has been satisfied:

                 (a)      The Agent has received from the Guarantor and the
Majority Banks a duly executed original or facsimile copy of this Waiver,

rely upon any document delivered to it in legible form by facsimile
transmission.

                 (b)      The Agent has received from the Guarantor and the
Company a copy of a resolution passed by the board of directors of each such
corporation, certified by the Secretary or an Assistant Secretary of such
corporation as being in full force and effect on the date hereof,
authorizing the execution, delivery and performance of this Waiver and the
Agreement Waiver, respectively.

                 (c)      All representations and warranties contained herein
are true and correct as of the Effective Date.

         5.      Reservation of Rights.  The Guarantor acknowledges and agrees
that neither the Agent's nor the Banks' execution and delivery of this Waiver,
shall be deemed (i) to create a course of dealing or otherwise obligate the
Agent or the Banks to forbear or execute similar waivers under the same or
similar circumstances in the future, or (ii) to waive, relinquish or


                                       3
<PAGE>   190
impair any right of the Agent or the Banks to receive any indemnity or similar
payment from any person or entity as a result of any matter arising from or
relating to the Transfer or the Offering.  The Guarantor hereby consents to the

the Agreement Waiver and hereby reaffirms and agrees that the Guaranty is in
full force and effect, without defense, offset or counterclaim.

         6.      Miscellaneous.

                 (a)      Except as herein expressly amended, all terms,
covenants and provisions  of the Guaranty are and shall remain in full force
and effect and all references therein to such Guaranty shall henceforth refer

assigns.  No third party beneficiaries are intended in connection with this
Waiver.

accordance with the law of the State of California.

                 (d)      This Waiver may be executed in any number of
counterparts, each of which shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument.

                 (e)      This Waiver, together with the Guaranty, contains the
entire and exclusive agreement of the parties hereto with reference to the
matters discussed herein and therein.  This Waiver supersedes all prior
drafts and communications with respect thereto.

                 (f)      If any term or provision of this Waiver shall be
deemed prohibited by or invalid under any applicable law, such


                                       4
<PAGE>   191
provision shall be invalidated without affecting the remaining provisions of

                         WAIVER AND SECOND AMENDMENT
                        TO STANDBY LETTER OF CREDIT AND
                            REIMBURSEMENT AGREEMENT


         THIS WAIVER AND SECOND AMENDMENT TO STANDBY LETTER OF CREDIT AND
REIMBURSEMENT AGREEMENT (the "Waiver and Amendment"), dated as of August 9,
1994, is entered into by and among Morrison Knudsen Corporation, an Ohio
corporation (the "Company"), BANK OF AMERICA NATIONAL TRUST AND SAVINGS
ASSOCIATION, as agent for itself and the Banks (the "Agent"), and the several
financial institutions party to the Letter of Credit and Reimbursement
Agreement (collectively, the "Banks").


                                    RECITALS

         A.      The Company, Banks, and Agent are parties to a Standby Letter
of Credit and Reimbursement Agreement dated as of August 4, 1992 as amended by
that Waiver and Amendment to Credit Agreement dated as of December 22, 1992,
as further modified by that Waiver to Standby Letter of Credit and
Reimbursement Agreement dated as of August 6, 1993, and as further modified by
that Waiver to Standby Letter of Credit and Reimbursement Agreement dated as of
March 31, 1994 (as so amended and modified, the "Credit Agreement") pursuant to
which the Agent and the Banks have extended certain credit facilities to the
Company and certain of its subsidiaries and pursuant to which the Issuing Bank
has issued a letter of credit for the benefit of Metra and for the account of
the Company.

         B.      The Company has reported to the Agent and the Banks the
existence of a certain event of default under the Credit Agreement.  The
Company has requested that the Banks waive such event of default and agree to
certain amendments of the Credit Agreement.

         C.      The Banks are willing to waive such default under the Credit
Agreement, and to amend the Credit Agreement, subject to the terms and
conditions of this Waiver and Amendment.


         NOW, THEREFORE, for valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto hereby agree as follows:


         1.      Defined Terms.  Unless otherwise defined herein, capitalized
terms used herein have the meanings, if any, assigned to them in the Credit
Agreement.


                                       1
<PAGE>   209
         2.      Default and waiver.

                 (a)      For purposes of this Waiver and Amendment, the
"Existing Default" means the default existing on this date under Section 7.13
of the Credit Agreement for the period ended on June 30, 1994 by reason of the
non-recurring charges to income for the quarter ended June 30, 1994 in the
aggregate pre-tax amount of $92,022,000 announced by the Company on July 19,
1994.

                 (b)      Subject to and upon the terms and conditions hereof,
the Banks hereby waive the Existing Default.

                 (c)      Nothing contained herein shall be deemed a waiver of
(or otherwise affect the Agent's or the Banks' ability to enforce) any other
default or Event of Default, including without limitation (i) any default or
Event of Default as may now or hereafter exist and arise from or otherwise be
related to the Existing Default (including without limitation any cross-default
arising under the Credit Agreement by virtue of any matters resulting from the
Existing Default), and (ii) any default or Event of Default arising at any time
after the Effective Date and which is the same as any of the Existing Default.


         3.      Amendments to Credit Agreement.

                 (a)      Section 1.01 of the Credit Agreement is amended by
inserting the following definitions in the proper alphabetical location:

                 "Moody's" means Moody's Investors Service, Inc. and any
         successor thereto that is a nationally recognized rating agency.

                 "S&P" means Standard & Poor's Corporation and any successor
         thereto that is a nationally recognized rating agency.


                 (b)      Section 2.08(a) of the Credit Agreement is amended by
inserting "(i)" after "(a)" and adding the following as clause (ii) to Section
2.08(a):

                          "(ii)   The Letter of Credit Fee will increase to
                 0.50% per annum if (A) the Company's long-term debt is rated
                 below BBB- by S&P or below Baa3 by Moody's, or (B) the
                 Company's commercial paper is rated below A3 by S&P or P3 by
                 Moody's, or (C) both of the Company's long term debt and
                 commercial paper is not rated by either S&P or Moody's. The
                 increase in the fee shall take effect as of the opening of
                 business on the day on which either of the rating agencies
                 announces a change in the relevant rating."


                                       2
<PAGE>   210
                 (c)      Section 6.01 of the Credit Agreement is amended by
adding the following as new subsection (e) to such Section:

                          "(e) as soon as available but not later than 45 days
         after the end of each of its fiscal quarters, a current schedule of
         Metra cars delivered, payments, and Letter of Credit status
         substantially in the form of the "METRA LETTER OF CREDIT - PROJECTED
         L/C REQUIREMENT" in the form of the chart provided in Tab 2 of the
         Company's "Presentation to Financial Institutions" dated July 1994."

                 (d)      Section 7.13 of the Credit Agreement is amended by
inserting "(i)" immediately after the caption to such Section and adding the
following as subsection (ii) to such Section:

                 "(ii)    For purposes of this Section, Consolidated Operating
         Income shall be calculated without giving effect to the non-recurring
         charges to income for the quarter ended June 30, 1994 in the aggregate
         pre-tax amount of $92,022,000 announced by the Company on July 19,
         1994."


         4.      Representations and Warranties.  The Company hereby represents
and warrants to the Agent and the Banks as follows:

                 (a)      Other than the Existing Default, no Default or Event
of Default has occurred and is continuing.

                 (b)      The execution, delivery and performance by the
Company of this Waiver and Amendment have been duly authorized by all necessary
corporate and other action and do not and will not require any registration
with, consent or approval of, notice to or action by, any Person (including any
Governmental Authority) in order to be effective and enforceable. The Credit
Agreement as amended by this Waiver and Amendment constitutes the legal, valid
and binding obligations of the Company, enforceable against it in accordance
with its respective terms, without defense, counterclaim or offset.

                 (c)      Subject to the Existing Default, all representations
and warranties of the Company contained in the Credit Agreement are true and
correct.

                 (d)      The Company is entering into this Waiver and
Amendment on the basis of its own investigation and for its own reasons,
without reliance upon the Agent and the Banks or any other Person.

         5.      Effective Date.  This Waiver and Amendment will become
effective as of August 9, 1994 (the "Effective Date"),


                                       3
<PAGE>   211
provided that each of the following conditions precedent has been satisfied:

                 (a)      The Agent has received from the Company and the
Majority Banks a duly executed original or facsimile copy of this waiver,
together with (i) a duly executed Guarantor Acknowledgment and Consent in the
form attached hereto (the "Consent"), and (ii) a Waiver to Guaranty ("Guaranty
Waiver") addressing matters relating to the subject of this Waiver, duly
executed by the Guarantor and the Majority Banks. The Agent may rely upon any
document delivered to it in legible form by facsimile transmission.

                 (b)      The Agent has received from the Company and the
Guarantor a copy of a resolution passed by the board of directors of each such
corporation, certified by the Secretary or an Assistant Secretary of such
corporation as being in full force and effect on the date hereof, authorizing
the execution, delivery and performance of this Waiver and the Guaranty Waiver,
respectively.

                 (c)      All representations and warranties contained herein
are true and correct as of the Effective Date.

                 (d)      The Agent has received from the Company (i) the sum
of $2,5OO for each Bank responding, by close of business on August 5, 1994, to 
the Agent's letter to the Banks dated August 1, 1994, describing the Company's
request for this Waiver and Amendment; and (ii) the sum agreed upon between the
Company and the Agent as the one-time non-refundable administrative agency fee
for the account of the Agent in connection with this Waiver and Amendment.


         6.      Reservation of Rights.  The Company acknowledges and agrees
that neither the Agent's nor the Banks' forbearance in exercising their rights
and remedies in connection with the Existing Default, nor the execution and
delivery by the Agent and the Banks of this Waiver and Amendment, shall be
deemed (i) to create a course of dealing or otherwise obligate the Agent or the
Banks to forbear or execute similar waivers under the same or similar
circumstances in the future, or (ii) to waive, relinquish or impair any right
of the Agent or the Banks to receive any indemnity or similar payment from any
person or entity as a result of any matter arising from or relating to the

any of the matters covered in Paragraph 2(a) of this Waiver and Amendment.


         3.      Amendment to the Guaranty.  Section 5.13 of the Guaranty is
amended by inserting "(i)" immediately after the caption to such Section and
adding the following as subsection (ii) to such Section:

         pre-tax amount of $92,022,000 announced by the Company on July 19,
         1994."


         4.      Representations and Warranties.  The Guarantor hereby

         6.      Reservation of Rights.  The Guarantor acknowledges and agrees

deemed prohibited by or invalid under any applicable law, such provision shall
be invalidated without affecting the remaining provisions of this Amendment or
