determines that any applicable condition specified in Article III has not been
satisfied, the Agent will promptly 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 on a day on which the 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 and
the amount being repaid shall be made available by such Bank to the Agent as
provided in
 17

subsection (b), or remitted by the Borrower to the Agent as provided in Section
2.12, as the case may be.

     (d)  Unless the Agent shall have received notice from a Bank prior to the
date of any Borrowing (or, in the case of a Base Rate Borrowing, prior to 12:00
Noon on the date of such 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 if such Bank shall not
have done so within five Domestic Business Days of demand therefor by the Agent,
then the Borrower, each severally agrees to pay 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
paid 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 make available to the Agent such corresponding amount,
such amount so made available shall constitute such Bank's Loan included in such
Borrowing for purposes of this Agreement.  Nothing in this subsection (d) shall
relieve any Bank of its obligation to make Loans in accordance with the terms
and conditions of this Agreement or relieve any Bank from responsibility for
default by it in such obligation.

     SECTION 2.05.  Notes.  (a)  The Loans of each Bank shall be evidenced by a
single Note payable to the order of such Bank for the account of its Applicable
Lending Office; provided that each Bank may, by notice to the Borrower and the
Agent, request that its Loans of a particular Class or Type be evidenced by a
separate Note.  Each such separate 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 Class or Type.  Each reference in this
Agreement to the "Note" of such Bank shall be deemed to refer to and include any
or all of such Notes, as the context may require.

          (b)  Upon receipt of each Bank's Note pursuant to Section 3.02(a), the
Agent shall forward such Note to such Bank.  Each Bank shall record the date,
amount, Class, Type and maturity of each Loan made by it and the date and amount
 18

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, endorse on the schedule forming a part thereof appropriate notations to
evidence the foregoing information with respect to each such Loan then
outstanding; provided that the inaccuracy of, or the failure of any Bank to
make, any such recordation or endorsement shall not affect the obligations of
the Borrower hereunder or under the Notes.  Each Bank is hereby irrevocably
authorized by the Borrower so to endorse its Note and to attach to and make a
part of its 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.

     (b)  Each CD 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 Applicable Margin plus the applicable Adjusted CD Rate;
provided that if any CD Loan shall, as a result of the further proviso to the
definition of Interest Period, have an Interest Period of less than 30 days,
such CD Loan 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.

          The "Adjusted CD Rate" applicable to any Interest Period means a rate
per annum determined pursuant to the following formula:
 19

                   [ 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.
 327.3(e) (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
 20

United States.  The Adjusted CD Rate shall be adjusted 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 the Interest Period applicable thereto, at a rate per annum
equal to the sum of the Applicable Margin plus the applicable London Interbank
Offered Rate.  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.

     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 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.

     (d)  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.

     (e)  Any overdue principal of and interest on any Loan shall bear interest,
payable on demand, for each day from and including the date payment thereof was
due to but excluding the date of actual payment, at a rate per annum equal to
the sum of 1% plus the rate applicable to Base Rate Loans for such day.
 21

          (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.

          (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.

          (h)  The "Applicable Margin" with respect to any Committed Loan at any
date is the applicable percentage amount set forth in the table below based on
the Type of such Loan and the Status on such date:

                Level I     Level II    Level III    Level IV     Level V
                 Status      Status       Status      Status       Status
                -------     --------    ---------    --------     --------
                                                    
Euro-Dollar     0.3125%        0.40%       0.55%       0.625%      0.675%
     Loans

CD Loans        0.4375%       0.525%      0.675%        0.75%       0.80%

     SECTION 2.08.  Fees.

     (a)  Commitment Fees.  During the period from and including the
Commencement Date to but not including the Termination Date, the Borrower shall
pay to the Agent for the account of the Banks ratably in proportion to their
Commitments a commitment fee at the Commitment Fee Rate on the daily amount by
which the aggregate amount of the Commitments exceeds the aggregate outstanding
principal amount of the Loans.

     For purposes of this subsection (a), "Commitment  Fee Rate" means a rate
per annum equal to 0.05%.

     (b)  Facility Fees.  During the period from and including the Commencement
Date to but not including the Termination Date (or such earlier or later date on
which the Commitments shall have terminated in their entirety and the Loans
shall have been repaid in full), the Borrower shall pay to the Agent for the
account of each Bank a facility fee at the Facility Fee Rate on the daily amount
of such Bank's
 22

Commitment (whether used or unused) and, after termination of the Commitments
and until repayment in full of the Loans, on the aggregate outstanding principal
amount of the Loans.

     For purposes of this subsection (b):

     "Facility Fee Rate" means a rate per annum equal to (i) for any day on
     which Level I Status exists 0.1375%,  (ii) for any day on which Level II
     Status exists, 0.15%, (iii) for any day on which Level III Status exists,
     0.20%, (iv) for any day on which Level IV Status exists, 0.25% and (v) for
     any day on which Level V Status exists, 0.325%.

     (c)  Payments.  Accrued commitment fees and facility fees shall be payable
quarterly in arrears on each March 31, June 30, September 30, and December 31 on
or prior to the date of termination of the Commitments in their entirety and
upon the date of termination of the Commitments in their entirety (and, if
later, the date the Loans shall be repaid in their entirety).

     SECTION 2.09.  Optional Termination or Reduction of Commitments.  The
Borrower 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
$50,000,000 or any larger integral multiple thereof, the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans.

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

     SECTION 2.11.  Optional Prepayments.  (a)  The Borrower may, upon at least
one Domestic Business Day's notice to the Agent, prepay any Base Rate Borrowing
(or any Money Market LIBOR Borrowing bearing interest at the Prime Rate pursuant
to Section 8.01(a)) in whole at any time, or from time to time in part in
amounts aggregating $50,000,000 or any larger integral multiple of $10,000,000,
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 included in such Borrowing.
 23

     (b)  Except as provided in Section 2.15(a), 2.17 or 8.02 the Borrower may
not prepay all or any portion of the principal amount of any Fixed Rate 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 of such prepayment and such notice shall not thereafter be
revocable by the Borrower.

     SECTION 2.12.  General Provisions as to Payments. (a)  The Borrower shall
make each payment of principal of, and interest on, the 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 specified in or pursuant to Section 9.01.  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 the Borrower prior to
the date on which any payment is due to the Banks hereunder that the Borrower
will not make such payment in full, the Agent may assume that the Borrower has
made such payment in full to the Agent on such date and the Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank.  If and to the extent
that the 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
 24

Bank until the date such Bank repays such amount to the Agent, at the Federal
Funds Rate.

     SECTION 2.13.  Funding Losses.  If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan (pursuant to Section 2.15(a) or
2.17, Article VI or VIII or otherwise) on any day other than the last day of the
Interest Period applicable thereto, or if the 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 2.15(a), or by any Bank in accordance with Section 2.17(a),
the Borrower shall reimburse each Bank on demand for any resulting loss or
expense incurred by it (or by any 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 Borrower 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
all commitment and facility fees shall be computed on the basis of a year of 360
days and paid for the actual number of days elapsed (including the first day but
excluding the last day).

     SECTION 2.15.  Termination of a Bank's Commitments; Designation of
Additional Banks.

     (a)  The Borrower may, upon at least three Domestic Business Days' notice
to the Agent and any Bank, terminate the Commitment of such Bank entirely,
provided that, if any Loans of such Bank are then outstanding, the Borrower
shall prepay each Loan of such Bank in full on the effective date of such
termination, together with accrued interest thereon and all accrued fees on such
Bank's Commitment to such effective date and all other amounts payable for the
account of such Bank hereunder.

          (b)  If the Borrower shall terminate the Commitment of any Bank
pursuant to the provisions of subsection (a) of this Section, the Borrower may
designate another bank or other banks (which may be one of the Banks) (in either
case, an "Additional Bank") to be parties to this
 25

Agreement, whose Commitments (or additional Commitments) shall not in the
aggregate exceed the amount of the Commitment so terminated.  Any Additional
Bank shall become a party to this Agreement and be considered a Bank hereunder
for all purposes if (i) it shall agree in writing to be bound by all of the
terms and provisions of this Agreement, such agreement to specify the amount of
the Commitment of such Additional Bank and to be otherwise in form and substance
satisfactory to the Agent, (ii) it shall make Committed Loans of each Type to
the Borrower in principal amounts which bear the same ratio to the amounts of
the Committed Loans of such Type of other Banks then outstanding as the
Commitment of such Additional Bank bears to the then Commitments of such other
Banks and (iii) a copy of such agreement and of evidence satisfactory to the
Agent of the making of such Committed Loans shall be furnished to the Agent and
the Banks.

     SECTION 2.16.  Agent's Fees.  The Borrower shall pay to the Agent for its
own account fees in the amounts and at the times previously agreed between them.

     SECTION 2.17.  Change of Control.  (a)  If a Change of Control shall occur
the Borrower will, within ten days after the occurrence thereof, give the Agent
notice thereof, and the Agent shall promptly notify each Bank thereof.  Such
notice shall describe in reasonable detail the facts and circumstances giving
rise thereto and the date of such Change of Control and each Bank may, by notice
to the Borrower and the Agent given not later than fifty days after the date of
such Change of Control, terminate its Commitment, which shall be terminated, and
declare the Note held by it (together with accrued interest thereon) and any
other amounts payable hereunder for its account to be, and such Note and such
amounts shall become, due and payable, in each case on the sixtieth day after
the date of such Change of Control (or if such day is not a Domestic Business
Day, the next succeeding Domestic Business Day), without presentment, demand,
protest or other notice of any kind, all of which are hereby waived by the
Borrower.

     For purposes of this Section, the following terms have the following
meanings:

     A "Change of Control" shall occur if (i) any "person" or "group" of persons
shall have acquired "beneficial ownership" (within the meaning of Section 13(d)
or 14(d) of the Securities Exchange Act of 1934, as amended, and the applicable
rules and regulations thereunder), of shares of Voting Stock representing 35% or
more of the Voting Power of the Borrower, (ii) during any period of
 26

twenty-five consecutive months, commencing before or after the date of this
Agreement, individuals who at the beginning of such twenty-five month period
were directors of the Borrower (together with any replacement or additional
directors whose election was recommended by incumbent management of the Borrower
or who were elected by a majority of directors then in office) cease to
constitute a majority of the board of directors of the Borrower, or (iii) any
Person or group of related Persons shall acquire all or substantially all of the
assets of the Borrower; provided, that a Change of Control shall not be deemed
to have occurred pursuant to clause (iii) above if the Borrower shall have
merged or consolidated with or transferred all or substantially all of its
assets to another corporation in compliance with the provisions of Section 5.02
and the surviving or successor or transferee corporation is no more leveraged
than was the Borrower immediately prior to such event.   For purposes of this
definition, the term "leveraged" when used with respect to any corporation shall
mean the percentage represented by the total assets of that corporation divided
by its stockholders' equity, in each case determined and as would be shown in a
consolidated balance sheet of such corporation prepared in accordance with
generally accepted accounting principles in the United States of America.

     "Voting Power" as applied to the stock of any corporation means the total
voting power represented by all outstanding Voting Stock of such corporation.

     "Voting Stock" as applied to the stock of any corporation means stock of
any class or classes (however designated) having ordinary voting power for the
election of the directors of such corporation, other than stock having such
power only by reason of the happening of a contingency.

     (b)  The Borrower agrees to indemnify each Bank and hold each Bank 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 for any Bank in connection with any investigative, administrative or
judicial proceeding, whether or not such Bank shall be designated a party
thereto) which may be incurred by any Bank (or by the Agent in connection with
its actions as Agent hereunder), in any way relating to or arising out of this
Agreement as amended from time to time and an actual, proposed or threatened
Change of Control (as defined above); provided that (i) no Bank shall have the
right to be indemnified hereunder for its own gross negligence or willful
misconduct as determined
 27

by final judgment of a court of competent jurisdiction; (ii) the Borrower shall
not, in connection with any such proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate law firm for any period for the Banks and the Agent (which shall be
selected by the Agent after consultation with the Borrower); (iii) the Agent and
each Bank shall consult with the Borrower from time to time at the request of
the Borrower regarding the conduct of the defense in any such proceeding and
(iv) the Borrower shall not be obligated to pay an amount of any settlement
entered into without its consent (which shall not be unreasonably withheld).






                                   ARTICLE III
                                        
                            CONDITIONS TO BORROWINGS

     outstanding principal amount of the Loans will not exceed the aggregate
     amount of the Commitments;
     
          (c)  the fact that the Borrowing will not contravene any provision of
     applicable law or of the certificate of incorporation or by-laws of the
     Borrower or of any agreement or instrument binding upon it;
     
          (d)  the fact that, immediately after such Borrowing, no Default shall
     have occurred and be continuing; and
     
          (e)  the fact that the representations and warranties of the Borrower

     representation and warranty set forth in Section 4.04(c) as to any material
     adverse change which has theretofore been disclosed in writing by the
     Borrower to the Banks) shall be true in all material respects 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

     Required Banks may reasonably request;
     
          (c)  receipt by the Agent of an opinion of Davis Polk & Wardwell,

     The Borrower represents and warrants that:

     SECTION 4.01.  Corporate Existence and Power.  The Borrower is a
corporation duly incorporated, validly existing and in good standing under the
laws of Delaware, 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; Contravention.
The execution, delivery and performance by the Borrower of this Agreement and
the Notes are within the Borrower'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 Borrower or of any agreement,
judgment, injunction, order, decree or other instrument binding upon the
Borrower or result in the creation or imposition of any Mortgage on any asset of
the Borrower or any of its Subsidiaries.

     SECTION 4.03.  Binding Effect.  This Agreement constitutes a valid and
binding agreement of the Borrower and the Notes, when executed and delivered in
accordance with this Agreement, will constitute valid and binding obligations of
the Borrower.

     SECTION 4.04.  Financial Information.

     (a)  The consolidated balance sheet of the Borrower as of December 31, 1993
and the related consolidated statements of income and cash flows for the fiscal
year then ended, reported on by Price Waterhouse and included in the Borrower's
1993 Form 10-K, copies of which have been delivered to the Agent for each of the
Banks, fairly present, in conformity with generally accepted accounting
principles, the consolidated financial position of the Borrower as of such date
and its consolidated results of operations and cash flows for such fiscal year.
 30

     (b)  The unaudited consolidated balance sheet of the Borrower as of June
30, 1994 and the related unaudited consolidated statements of income and cash
flows for the six months then ended, set forth in the Borrower's quarterly
report for the fiscal quarter ended June 30, 1994 as filed with the Securities
and Exchange Commission on Form 10-Q, copies of which have been delivered to the
Agent for 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 paragraph (a) of this Section, the consolidated
financial position of the Borrower as of such date and its consolidated results
of operations and cash flows for such six month period (subject to normal
year-end adjustments).

     (c)  Since June 30, 1994 there has been no change in the consolidated
financial position or operations of the Borrower, considered as a whole, which
would materially and adversely affect the ability of the Borrower to perform its
obligations hereunder and under the Notes.

     SECTION 4.05.  Litigation.  Except as set forth in the Borrower's 1993 Form
10-K and quarterly report on Form 10-Q for the fiscal quarter ended June 30,
1994, there is no action, suit, arbitration or other proceeding, inquiry or
investigation, at law or in equity, or before or by any court, public board or
body, arbitrator or arbitral body, pending against the Borrower or of which the
Borrower has otherwise received official notice or which to the knowledge of the
Borrower is threatened against the Borrower, wherein there is a reasonable
possibility of an unfavorable decision, ruling or finding which would materially
adversely affect the Borrower's ability to perform its obligations under this
Agreement and the Notes and since the dates of the respective descriptions of
proceedings contained in the reports identified above, there has been no change
in the status of such proceedings which would materially adversely affect the
Borrower's ability to perform its obligations under this Agreement and the
Notes.

     SECTION 4.06.  Environmental Matters.  The Borrower does not presently
anticipate that remediation costs and penalties associated with environmental
laws, to the extent not previously provided for, will have a material adverse
effect on the consolidated financial position of the Borrower.

     SECTION 4.07.  Taxes.  United States Federal income tax returns of the
Borrower have been examined and closed through the fiscal year ended December
31, 1987.  The Borrower has filed all United States Federal income tax
 31

returns and all other material tax returns that are required to be filed by it
and has paid all material taxes due pursuant to such returns or pursuant to any
assessment received by it, except for any such taxes being diligently contested
in good faith and by appropriate proceedings. Adequate reserves have been
provided on the books of the Borrower in respect of all taxes or other
governmental charges in accordance with generally accepted accounting
principles, and no tax liabilities in excess of the amount so provided are
anticipated that could materially and adversely affect the consolidated
financial position or operations of the Borrower, considered as a whole.

     SECTION 4.08.  Compliance with Laws.  The Borrower and Marathon Oil Company
are in compliance with all applicable laws, rules and regulations, other than
such laws, rules or regulations (i) the validity or applicability of which the
Borrower or Marathon Oil Company is contesting in good faith or (ii) failure to
comply with which cannot reasonably be expected to have consequences which would
materially and adversely affect the consolidated financial position or
operations of the Borrower, considered as a whole.

     SECTION 4.09.  Marathon.  Marathon Oil Company 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

                                    COVENANTS
                                        
                                        
     The Borrower agrees that, so long as any Bank has a Commitment hereunder or
any amount payable under any Note remains unpaid:

     SECTION 5.01.  Information.  The Borrower will deliver to the Agent for
each of the Banks:

          (a)  as soon as available and in any event within 90 days after the
     end of each fiscal year of the Borrower, a consolidated balance sheet of
     the Borrower as of the end of such fiscal year and the related consolidated
     statements of income and cash flows for such fiscal year, setting forth in
     each case in
      32
     
     comparative form the figures for the previous fiscal year, all reported on
     by Price Waterhouse or other independent public accountants of nationally
     recognized standing;
     
          (b)  as soon as available and in any event within 45 days after the
     end of each of the first three quarters of each fiscal year of the
     Borrower, a consolidated balance sheet of the Borrower as of the end of
     such quarter and the related consolidated statements of income and cash
     flows for such quarter and for the portion of the Borrower's fiscal year
     ended at the end of such quarter, setting forth in each case in comparative
     form the figures for the corresponding quarter and the corresponding
     portion of the Borrower's previous fiscal year;
     
          (c)  simultaneously with the delivery of each set of financial
     statements referred to in clause (a) above, a certificate of the chief
     financial officer or the chief accounting officer of the Borrower stating
     whether there exists on the date of such certificate any Default and, if
     any Default then exists, setting forth the details thereof and the action
     which the Borrower is taking or proposes to take with respect thereto;
          (d)  forthwith upon the occurrence of any Default, a certificate of
     the chief financial officer or the chief accounting officer of the Borrower
     setting forth the details thereof and the action which the Borrower is
     taking or proposes to take with respect thereto;
     
          (e)  promptly upon the mailing thereof to the shareholders of the
     Borrower generally, copies of all financial statements, reports and proxy
     statements so mailed;
     
          (f)  promptly upon the filing thereof, copies of all annual, quarterly
     or other reports which the Borrower shall have filed with the Securities
     and Exchange Commission; and
     
          (g)  from time to time such additional information regarding the
     financial position or business of the Borrower and its Subsidiaries and
     affiliates as the Agent, at the request of any Bank, may reasonably
     request.
     
     SECTION 5.02.  Consolidations and Mergers.  So long as this Agreement shall
remain in effect, the Borrower shall not consolidate or merge with or into any
other Person
 33

or convey, transfer or lease all or substantially all of its assets as an
entirety to any Person, unless:

          (i)  either (x) the Borrower shall be the corporation surviving such
     merger or (y) the corporation formed by such consolidation or into which
     Borrower is merged or the Person which acquires by conveyance, transfer or
     lease all or substantially all of the assets of the Borrower as an entirety
     shall be a corporation organized and existing under the laws of the United
     States of America or any state or the District of Columbia and shall
     execute and deliver to each Bank an agreement, in form and substance
     satisfactory to each Bank, containing an assumption by such successor
     corporation of the due and punctual performance and observance of each
     covenant and condition of this Agreement to be performed or observed by the
     Borrower;
     
          (ii) the Borrower or such successor corporation, as the case may be,
     shall have a consolidated net worth (that is, total consolidated assets
     less total consolidated liabilities) of no less than the net worth (as so
     determined) of the Borrower immediately prior to such consolidation, merger
     or conveyance, transfer or lease of all or substantially all of the
     Borrower's assets as an entirety to such Person; and
     
          (iii) immediately after giving effect to such transaction, no Default
     shall have occurred and be continuing.
     
Upon any consolidation or merger in which the Borrower is not the surviving
corporation or any conveyance, transfer or lease of all or substantially all of
the assets of the Borrower as an entirety in accordance with this Section, the
successor corporation formed by such consolidation or into which the Borrower is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Borrower
under this Agreement with the same effect as if such successor corporation had
been named as the Borrower herein.  No such conveyance, transfer or lease of all
or substantially all of the assets of the Borrower as an entirety shall have the
effect of releasing the Borrower or any successor corporation which shall
theretofore have become such in the manner prescribed in this Section from any
liability hereunder.

          SECTION 5.03.  Use of Proceeds.   The proceeds of the Loans made under
this Agreement will be used by the
 34

Borrower for its general corporate purposes.  None of such proceeds will be used
in violation of any applicable law or regulation including, without limitation,
Regulation U of the Board of Governors of the Federal Reserve System.

     SECTION 5.04.  Termination of Prior Credit Agreements.  On or prior to the
earlier of (i) the date of the first Borrowing hereunder and (ii) August 30,
1994 (the "Commencement Date"), the Borrower will terminate, or cause to be
terminated, in their entirety the commitments of the banks under the Existing
Credit Agreements.  The Borrower shall promptly notify the Agent of the
termination of the above referenced agreements, and such termination shall be a
condition precedent to the effectiveness of the Commitments hereunder.

     SECTION 5.05.  Negative Pledge.   If the Borrower or any Subsidiary of the
Borrower shall mortgage, pledge, encumber, or subject to a lien (hereinafter to
"Mortgage" or a "Mortgage") as security for any indebtedness for money borrowed
(x) any blast furnace facility or raw steel producing facility, or rolling mills
which are a part of a plant which includes such a facility; or (y) any property
capable of producing oil or gas; and, which in either case, is located in the
United States and determined by the Board of Directors of the Borrower, in good
faith, to be a principal property, the Borrower will secure or will cause such
Subsidiary to secure the Borrower's obligations hereunder equally and ratably
with all indebtedness or obligations secured by the Mortgage then being given
and with any other indebtedness of the Borrower or such Subsidiary then entitled
thereto; provided, however, this covenant shall not apply in the case of:

          (i)  any Mortgage existing on the date of this Agreement (whether or
     not such Mortgage includes an after-acquired property provision);
     
          (ii)  any Mortgage, including a purchase money Mortgage, incurred in
     connection with the acquisition of any property (for purposes hereof the
     creation of any Mortgage within 180 days after the acquisition or
     completion of construction of such property shall be deemed to be incurred
     in connection with the acquisition of such property), the assumption of any
     Mortgage previously existing on such acquired property or any Mortgage
     existing on the property of any corporation when such corporation becomes a
     Subsidiary of the Borrower;
 35
     
          (iii)  any Mortgage on such property in favor of the United States of
     America, any state, or any agency, department, political subdivision or
     other instrumentality of either, to secure partial, progress or advance
     payments to the Borrower or any Subsidiary of the Borrower pursuant to the
     provisions of any contract or any statute;
     
          (iv)  any Mortgage on such property in favor of the United States of
     America, any state, or any agency, department, political subdivision or
     other instrumentality of either, to secure borrowings by the Borrower or
     any Subsidiary of the Borrower for the purchase or construction of the
     property mortgaged;
     
          (v)  any Mortgage in connection with a sale or other transfer of (i)
     oil or gas in place for a period of time or in an amount such that the
     purchaser will realize therefrom a specified amount of money or specified
     amount of minerals or (ii) any interest in property of the character
     commonly referred to as an "oil payment" or "production payment";
     
          (vi)  any Mortgage on any property arising in connection with or to
     secure all or any part of the cost of the repair, construction,
     improvement, alteration, exploration, development or drilling of such
     property or any portion thereof;
     
          (vii)  any Mortgage on any pipeline, gathering system, pumping or
     compressor station, pipeline storage facility, other pipeline facility,
     drilling equipment, drilling platform, drilling barge, any movable railway,
     marine or automotive equipment, gas plant, office building, storage tank,
     or warehouse facility, any of which is located on any property included
     herein under clause (y) above;
     
          (viii)  any Mortgage on any equipment or other personal property used
     in connection with any property included herein under clause (y) above;
     
          (ix)  any Mortgage on any property included herein under clause (y)
     above arising in connection with the sale of accounts receivable resulting
     from the sale of oil or gas at the wellhead; or
     
          (x)  any renewal of or substitution for any Mortgage permitted under
     the preceding clauses.
 36
     
Notwithstanding the foregoing restriction contained in this Section 5.05, the
Borrower may and may permit its Subsidiaries to incur liens or grant Mortgages
on property covered by the restriction above so long as the net book value of
the property so encumbered together with all property subject to the restriction
on sale and leasebacks contained in Section 5.06 does not at the time such lien
or Mortgage is granted exceed 5% of Consolidated Net Tangible Assets.
"Consolidated Net Tangible Assets" means the aggregate value of all assets of
the Borrower and its Subsidiaries on a consolidated basis after deducting
therefrom (a) all current liabilities (excluding all long-term debt due within
one year), (b) all investments in unconsolidated subsidiaries and all
investments accounted for on the equity basis and (c) all goodwill, patent and
trademarks, unamortized debt discount and other similar intangibles (all
determined in conformity with generally accepted accounting principles and
calculated on a basis consistent with the Borrower's most recent audited
consolidated financial statements).

     SECTION 5.06.  Sale and Leaseback.  The Borrower will not, nor will it
permit any Subsidiary of the Borrower to, sell or transfer (x) any blast furnace
facility or raw steel producing facility, or rolling mills which are a part of a
plant which includes such a facility; or (y) any property capable of producing
oil or gas; which in either case is located in the United States and determined
by the Board of Directors of the Borrower, in good faith, to be a principal
property, with the intention of taking back a lease of such property; provided,
however, this covenant shall not apply if:

          (i)  the sale is to a Subsidiary of the Borrower (or to the Borrower
     in the case of a Subsidiary);
     
          (ii)  the lease is for a temporary period by the end of which it is
     intended that the use of such property by the lessee will be discontinued;
     
          (iii)  the Borrower or a Subsidiary of the Borrower could, in
     accordance with Section 5.05, Mortgage such property without equally and
     ratably securing the Borrower's obligations hereunder;
     
     (iv)  the transfer is incident to or necessary to effect any operating,
farm out, farm in, unitization, acreage exchange, acreage contributions, bottom
hole or dry hole arrangements or pooling agreement or any other agreement of the
same general nature relating to the acquisition, exploration, maintenance,
development and
 37

     operation of oil or gas properties in the ordinary course of business or as
     required by regulatory agencies having jurisdiction over the property; or
     
          (v)  (A) the Borrower promptly informs the Agent of such sale, (B) the
     net proceeds of such sale are at least equal to the fair value (as
     determined by resolution adopted by the Board of Directors of the Borrower)
     of such property and (C) the Borrower shall, and in any such case the
     Borrower covenants that it will, within 180 days after such sale, apply an
     amount equal to the net proceeds of such sale to the retirement of debt of
     the Borrower, or of a Subsidiary of the Borrower in the case of property of
     such Subsidiary, maturing by its terms more than one year after the date on
     which it was originally incurred (herein called "funded debt"); provided
     that the amount to be applied to the retirement of funded debt of the
     Borrower or of a Subsidiary of the Borrower shall be reduced by the amount
     equal to the amount below if, within 75 days after such sale, the Borrower
     shall deliver to the Agent an officer's certificate (1) stating that on a
     specified date after such sale the Borrower or a Subsidiary of the
     Borrower, as the case may be, voluntarily retired a specified principal
     amount of funded debt, (2) stating that such retirement was not effected by
     payment at maturity or pursuant to any applicable mandatory sinking fund or
     prepayment provision (other than provisions requiring retirement of any
     funded debt of the Borrower or a Subsidiary of the Borrower, as the case
     may be, under the circumstances referred to in this Section 5.06) and (3)
     stating the then optional redemption or prepayment price applicable to
     funded debt so retired or, if there is no such price applicable, the amount
     applied by the Borrower or a Subsidiary of the Borrower, as the case may
     be, to the retirement of such funded debt.  The Borrower shall deliver to
     the Agent a certified copy of the resolution of the Board of Directors of
     the Borrower referred to in paragraph (v)(B) above and an officer's
     certificate setting forth all material facts under this Section 5.06.  The
     term retirement of such funded debt shall include the in-substance
     defeasance of such funded debt in accordance with then applicable
     accounting rules.

                                    DEFAULTS
                                        
                                        
     SECTION 6.01.  Events of Default.  If one or more of the following events
("Events of Default") shall have occurred and be continuing:

          (a)  the Borrower shall fail to pay when due any principal of any
     Note, or shall fail to pay within five Domestic Business Days after the due
     date thereof any interest on any Note;
     
          (b)  the Borrower shall fail to observe or perform any covenant
     contained in Section 5.02;
     
          (c)  the Borrower shall fail to observe or perform any covenant or
     agreement contained in this Agreement (other than those contained in
     Section 5.05 or 5.06 or those covered by clauses (a) or (b) above) for 10
     days after written notice thereof has been given to the Borrower by the
     Agent at the request of any Bank;
     
          (d)  the Borrower shall fail to observe or perform any covenant
     contained in Section 5.05 or 5.06 for 30 days after written notice thereof
     has been given to the Borrower by the Agent at the request of any Bank;
     provided that the continuation of such failure for 30 days or longer after
     such notice shall not constitute an Event of Default if (i) such failure is
     curable but cannot be cured within 30 days, (ii) the Borrower, upon the
     aforesaid notice from the Agent, institutes curative action as promptly as
     practicable, and (iii) the Borrower diligently pursues such action to
     completion within a reasonable period, which period shall not, in any
     event, continue for more than 90 days after the aforesaid notice from the
     Agent;
     
          (e)  any representation, warranty, certification or statement made by
     the Borrower in this Agreement or in any certificate, financial statement
     or other document delivered pursuant to this Agreement shall prove to have
     been incorrect in any material respect when made or deemed made;
     
     (f)  the Borrower 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
 39

     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, or shall
     make a general assignment for the benefit of creditors, or shall fail
     generally to pay its debts as they become due, or shall take any corporate
     action to authorize any of the foregoing;
     
          (g)  an involuntary case or other proceeding shall be commenced
     against the Borrower seeking liquidation, reorganization or other relief
     with respect to it 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, and such involuntary case or other
     proceeding shall remain undismissed and unstayed for a period of 60 days;
     or an order for relief shall be entered against the Borrower under the
     federal bankruptcy laws as now or hereafter in effect; or
     
          (h)  notice of intent to 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 any member of the ERISA Group shall incur and not satisfy a withdrawal
     liability under Title IV of ERISA in respect of a Multiemployer Plan in
     excess of (i) $50,000,000 for any year or (ii) $250,000,000 in the
     aggregate;
     
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 Borrower
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 Borrower declare the Notes (together with
accrued interest thereon) and any other amounts payable hereunder to be, and the
Notes and such amounts shall thereupon become, immediately due and payable
without presentment, demand, protest or other notice of any kind, all of which
are hereby waived by the Borrower; provided that in the case of any of
 40

the Events of Default specified in paragraph (f) or (g) above, without any
notice to the Borrower or any other act by the Agent or the Banks, the
Commitments shall thereupon terminate and the Notes (together with accrued
interest thereon) and any other amounts payable hereunder shall become
immediately due and payable without presentment, demand, protest or other notice
of any kind, all of which are hereby waived by the Borrower.

     SECTION 6.02.  Notice of Default.  The Agent shall give notice to the
Borrower under Section 6.01(c) or (d) promptly upon being requested to do so by
any Bank and shall thereupon notify all the Banks thereof.

     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 the Borrower or any Subsidiary or affiliate of the Borrower as if
it were not the Agent hereunder.

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

     SECTION 7.04.  Consultation with Experts.  The Agent may consult with legal
counsel (who may be counsel for the 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.
 41

     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 or their own gross negligence or willful misconduct; provided
that the provisions of this sentence are for the sole benefit of the Agent, its
affiliates and their respective directors, officers, agents and employees and
shall not release any Bank from liability it would otherwise have to the
Borrower.  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 Borrower; (iii) the satisfaction of any condition specified in
Article III, except receipt of items required to be delivered to the Agent; or
(iv) the validity, effectiveness or genuineness of 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 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
Borrower) against any cost, expense (including 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, the Managing Agent, any Co-
Agent or any other Bank, and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement.  Each 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.
 42

     SECTION 7.08.  Successor Agent.  The Agent may resign at any time by giving
notice thereof to the Banks and the Borrower.  Upon any such resignation, the
Borrower shall have the right to appoint a successor Agent from among the Banks,
subject to the approval of the Required Banks, which shall not be unreasonably
withheld.  If no successor Agent shall have been so appointed by the Borrower
and approved by the Required Banks, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving of 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.  Co-Agents.  The Co-Agents shall have no responsibility,
obligation or liability under this Agreement in their respective capacities as
Co-Agents.

                                  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
or the London Interbank Offered Rate, as the case may
 43

     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 Borrower and the Banks,
whereupon until the Agent notifies the Borrower 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 Prime 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 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 made or issued
after the date of this Agreement (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 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 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 as a result of any
of the foregoing 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
 44

then outstanding principal amount of each such Euro-Dollar Loan, together with
accrued interest 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, unless the Borrower elects pursuant
to Section 8.05 not to borrow such Base Rate Loan.

     SECTION 8.03.  Increased Cost.  (a)  If on or after (i) the date hereof, in
the case of any Committed Loan or any obligation to make Committed Loans or (ii)
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 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
made or issued after the applicable date set forth above (whether or not having
the force of law) of any such authority, central bank or comparable agency:

          (A)  shall subject any Bank (or its Applicable Lending Office) to any
     tax, duty or other charge with respect to its Fixed Rate Loans, its Note or
     its obligation to make Fixed Rate Loans, or shall change the basis of
     taxation of payments to any Bank (or its Applicable Lending Office) of the
     principal of or interest on its Fixed Rate Loans or any other amounts due
     under this Agreement in respect of its Fixed Rate Loans or its obligation
     to make Fixed Rate Loans (except for taxes based on or measured in whole or
     in part by the gross income, net income, gross revenue or gross receipts of
     such Bank or its Applicable Lending Office imposed by the jurisdiction in
     which such Bank's principal executive office or Applicable Lending Office
     is located); or
     
     (B)  shall impose, modify or deem applicable any reserve, special deposit,
insurance assessment or similar requirement (including, without limitation, any
such requirement imposed by the Board of Governors of the Federal Reserve System
or the Federal Deposit Insurance Corporation, but excluding (x) with respect to
any CD Loan any such requirement included in an applicable Domestic Reserve
Percentage or Assessment Rate, (y) with respect to any Euro-Dollar Loan any such
requirement with respect to which such Bank is entitled
 45

     to compensation during the relevant Interest Period pursuant to Section
     8.03(d) and (z) any such requirement with respect to which such Bank is
     entitled to compensation pursuant to Section 8.03(b)) 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 (or, in the
case of Regulation D, to impose a cost on) 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 Borrower 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 the adoption after the date
hereof of any applicable law, rule or regulation regarding capital adequacy, or
any change after the date hereof in any such law, rule or regulation or 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 after the date hereof 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 would have achieved
but for such adoption, change or compliance (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 Borrower shall pay to such Bank such additional
amount or amounts as will compensate such Bank (or its Parent) for such
reduction; provided that the Borrower shall not be obligated to compensate any
Bank (or its Parent) in respect of any such reduction in respect of periods more
than six months prior to the date on which such Bank shall have notified the
Borrower of its intention to demand such
 46

compensation and setting forth the amount or the specific basis of computation
thereof.

     (c)  Each Bank will promptly notify the Borrower and the Agent of any event
of which it has knowledge, occurring after the date hereof, which will entitle
such Bank to compensation pursuant to Section 8.03(a) or (b) 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 Section 8.03(a) or (b) 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.

     (d)  The Borrower shall pay for the account of each Bank on the last day of
each Interest Period with respect to any Euro-Dollar Loan (and, if such Interest
Period is longer than three months, at intervals of three months after the first
day thereof), if at any time during such Interest Period such Bank shall be
required to maintain (and shall maintain in amounts deemed by such Bank to be
material) reserves against any category of liabilities which includes deposits
by reference to which the interest rate on Euro-Dollar Loans is determined as
provided in this Agreement or against any category of extensions of credit or
other assets of such Bank which includes loans by a non-United States office of
such Bank to United States residents (including without limitation reserves
against "Eurocurrency liabilities" under Regulation D), an additional amount
(determined by such Bank and notified to the Borrower and the Agent) equal to
the product of the following for each day during such Interest Period:

          (i)  the principal amount of the Euro-Dollar Loan of such Bank to
     which such Interest Period relates outstanding on such day; and
     
          (ii)  the remainder of (x) a fraction the numerator of which is the
     applicable London Interbank Offered Rate (expressed as a decimal) and the
     denominator of which is one minus the stated rate (expressed as a decimal)
     at which such reserve requirements are imposed on such Bank on such day
     minus (y) such numerator; and
     
          (iii)  1/360.
 47

If a Bank which is entitled to require payment by the Borrower of the amount
provided for in this Section 8.03(d) determines that a lesser amount is required
to compensate it for the costs of the reserve requirements referred to therein,
such Bank may, but shall not be obligated to, reduce the amount payable by the
Borrower thereunder to a lesser amount specified in the notice delivered
pursuant to this Section 8.03(d).

     (e)  Each Bank organized under the laws of a jurisdiction outside the
United States of America agrees that it shall deliver to the Borrower  (with a
copy to the Agent) (i) within 30 days after the date of execution of this
Agreement, two duly completed copies of United States Internal Revenue Service
Form 1001 or 4224, as appropriate, promulgated pursuant to the Code, indicating
that such Bank is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes as permitted
by the Code, (ii) from time to time, such extensions or renewals of such forms
(or successor forms) as may reasonably be requested by the Borrower but only to
the extent such Bank determines that it may properly effect such extensions or
renewals under applicable tax treaties, laws, regulations and directives and
(iii) in the event of a transfer of any Loan to an affiliate of such Bank, a new
Internal Revenue Service Form 1001 or 4224 (or any successor form), as the case
may be, for such affiliate.  The Borrower and the Agent shall each be entitled
to rely on such forms in its possession until receipt of any revised or
successor form pursuant to the preceding sentence.

     SECTION 8.04.  Base Rate Loans Substituted for Affected Fixed Rate Loans.
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 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 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,
has been repaid, all payments of principal which would otherwise be applied to
repay such
 48

Fixed Rate Loans shall be applied to repay its Base Rate Loans instead.

     SECTION 8.05.  Election Not to Borrow.  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, the Borrower may elect to
terminate this Agreement as to such Bank, and in connection therewith not to
borrow any Base Rate Loan provided for in Section 8.02 or to prepay any Base
Rate Loan made pursuant to Section 8.02 or 8.04, provided that the Borrower (i)
notifies such Bank through the Agent of such election at least three Euro-Dollar
Business Days before any date fixed for such a borrowing or such a prepayment,
as the case may be, and (ii) repays all of such Bank's outstanding Loans at the
end of the respective Interest Periods applicable thereto or as otherwise
required by Section 8.02, together with accrued interest thereon and all accrued
fees on such Bank's Commitment to such date and all other amounts payable for
the account of such Bank hereunder.  Upon receipt by the Agent of such notice,
the Commitment of such Bank shall terminate.

     SECTION 8.06.  Notice Mandatory.  The Agent or the affected Bank, as the
case may be, shall promptly give notice to the Borrower when circumstances which
gave rise to a suspension of the obligations of the Banks or a Bank to make
loans of a particular Type pursuant to Section 8.01 or 8.02, or to a demand for
compensation under Section 8.03, no longer exist.


                                   ARTICLE IX
                                        
                                  MISCELLANEOUS
                                        
                                        
     SECTION 9.01.  Notices.  All notices, requests and other communications to
any party hereunder shall be in writing (including bank wire, telex, telecopy or
similar writing) and shall be given to such party:  (x) in the case of the
Borrower or the Agent, at its address or telex or telecopy number set forth on
the signature pages hereof, (y) in the case of any Bank, at its address or telex
or telecopy number set forth in its Administrative Questionnaire or (z) in the
case of any party, at such other address or telex or telecopy number as such
party may hereafter specify for the purpose by notice to the Agent and the
Borrower.  Each such notice, request or other communication shall be effective
(i) if given by telex, when such telex is transmitted to the telex number
specified in this Section and the appropriate
 49

answerback is received, (ii) if given by telecopy, when such telecopy is
transmitted to the telecopy number specified in this Section and appropriate
confirmation of transmission 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 VIII and notices to the Borrower under Section 6.01(c) shall not
be effective until received.

     SECTION 9.02.  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 9.03.  Expenses; Documentary Taxes.  The Borrower shall pay (i) all
out-of-pocket expenses of the Agent, including fees and disbursements of Davis
Polk & Wardwell, special counsel for the Agent, in connection with the
preparation 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 out-of-pocket expenses incurred by the Agent or any Bank,
including fees and disbursements of counsel, in connection with such Event of
Default and collection and other enforcement proceedings resulting therefrom.
The Borrower shall indemnify each Bank against any transfer taxes, documentary
taxes, assessments or charges made by any governmental authority by reason of
the execution and delivery of this Agreement or the Notes.

     SECTION 9.04.  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 at
such time 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
 50

set-off or counterclaim it may have and to apply the amount subject to such
exercise to the payment of indebtedness of the Borrower other than its
indebtedness under the Notes. The 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 the Borrower in the amount of such participation.

     SECTION 9.05.  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 Borrower 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) subject
to Section 2.15, increase any Commitment of any Bank 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 (iv) change the
percentage of the Commitments or the percentage 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; and further provided that no such amendment or
waiver shall materially change, to the detriment of any Bank, any provision of
Article VIII hereof without the consent of such Bank.

     SECTION 9.06.  Successors and Assigns.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all 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
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement.
 51

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 Borrower hereunder including, without limitation,
the right to approve any amendment, modification or waiver of any provision of
this Agreement; provided that such participation agreement may provide that such
Bank will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii) or (iii) of Section 9.05 without the consent of
the Participant.  The Borrower agrees 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 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 all or any portion of its rights under
this Agreement and the Notes to an affiliate of such Bank or to a Federal
Reserve Bank.  No such assignment shall release the transferor Bank from its
obligations hereunder without the written consent of the Borrower and the Agent
(in which case the provisions of subsection (d) shall be applicable).  The
Borrower and the Agent shall be entitled to treat each Bank as the holder of the
Notes issued to its order and owner of the Loans evidenced thereby unless and
until notice of assignment pursuant to this subsection (c) is received by them.

     (d)  Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all or a portion of its rights and obligations
under this Agreement and its Note, and such Assignee shall assume such rights
and obligations, pursuant to an instrument substantially in the form of Exhibit
G executed by such Assignee and such transferor Bank, with (and subject to) the
subscribed consent of the Borrower and the Agent (which consent of the Agent
shall not be unreasonably withheld); provided 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 an 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
 52

any party shall be required.  Upon the consummation of any assignment pursuant
to this subsection (d), the transferor Bank, the Agent and the Borrower shall
make appropriate arrangements so that, if required, a new Note is 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 $2,000.  If the Assignee is not incorporated under the laws of the United
States of America or a state thereof, it shall, prior to the first date on which
interest or fees are payable hereunder for its account, deliver to the Borrower
and the Agent certification as to exemption from deduction or withholding of any
United States federal income taxes in accordance with Section 8.03(e).

     (e)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 than such
Bank would have been entitled to receive with respect to the rights transferred,
unless such transfer is made with the Borrower's prior written consent or by
reason of the provisions of Section 8.02 or 8.03 requiring such Bank to
designate a different Applicable Lending Office under certain circumstances.

     SECTION 9.07.  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 of the Board of Governors of the Federal
Reserve System) as collateral in the extension or maintenance of the credit
provided for in this Agreement.

     SECTION 9.08.  New York Law.  This Agreement and each Note shall be
construed in accordance with and governed by the law of the State of New York.

     SECTION 9.09.  Counterparts; 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.
Subject to Section 5.04, this Agreement shall become effective when the Agent

hereof, appropriate notations to evidence the foregoing information with respect

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  10260-0060

Dear Sirs:


     I am General Counsel of USX Corporation, a Delaware corporation (the
"Borrower").  I refer to the Credit Agreement (the "Credit Agreement") dated as
of August 18, 1994 among the Borrower, the Co-Agents and other Banks listed on
the signature pages thereof, Chemical Bank, as Managing Agent, and Morgan
Guaranty Trust Company of New York, as Agent.  Terms defined in the Credit
Agreement are used herein as therein defined.

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

     Upon the basis of the foregoing, I am of the opinion that:

     1.  The Borrower is a corporation duly incorporated, validly existing and
in good standing under the laws of
 2

Delaware and is qualified to do business in each jurisdiction where the
ownership of its property or the conduct of its business requires such 
qualification.  The Borrower has all the corporate power required to conduct 
its business as now conducted.

     2.  The execution, delivery and performance by the Borrower of the Credit
Agreement and the Notes are within the Borrower'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 Borrower or
of any agreement, judgment, injunction, order, decree or other instrument
binding upon the Borrower or result in the creation or imposition of any
Mortgage on any asset of the Borrower or any of its Subsidiaries.

     3.  The Credit Agreement constitutes a valid and binding agreement of the
Borrower and the Notes constitute valid and binding obligations of the Borrower.

     4.  Except as set forth in the Borrower's 1993 Form 10-K and quarterly
report on Form 10-Q for the fiscal quarter ended June 30, 1994, there is no 
action, suit, arbitration or other proceeding, inquiry or investigation, at law 
or in equity, or before or by any court, public board or body, arbitrator or
arbitral body, pending against the Borrower or of which the Borrower has
otherwise received official notice or which to my knowledge is threatened 
against the Borrower, wherein there is a reasonable possibility of an
unfavorable decision, ruling or finding which would materially adversely affect
the Borrower's ability to perform its obligations under the Credit Agreement
and the Notes and since the dates of the respective descriptions of proceedings
contained in the reports identified above, there has been no change in the
status of such proceedings which would materially adversely affect the
Borrower's ability to perform its obligations under the Credit Agreement and
the Notes.

     The foregoing opinion is limited to the laws of the Commonwealth of
Pennsylvania, the Federal laws of the United States of America and the General
Corporation law of the State of Delaware.  I am a member of the Bar of the State
of Ohio, and as to matters of Pennsylvania law, I have relied on the advice of
members of the Legal Department admitted to practice in Pennsylvania.  As the
Credit Agreement and the Notes are by their terms governed by the laws of the
State of New York, the foregoing opinion should be understood to conclude that
(i) a Pennsylvania court or a Federal court sitting in Pennsylvania
 3

would give effect to the choice of New York law to govern the Credit Agreement
and the Notes and (ii) under the internal laws of the State of Pennsylvania the
Credit Agreement constitutes a valid and binding agreement of the Borrower and
the Notes constitute valid and binding obligations of the Borrower.

                              Very truly yours,
                                                      EXHIBIT F

                                         Credit Agreement]


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  10260-0060

Dear Sirs:


     We have participated in the preparation of the Credit Agreement (the 
"Credit Agreement") dated as of August 18, 1994 among USX Corporation, a
Delaware corporation (the "Borrower"), the Co-Agents and other banks listed on 
the signature pages thereof (the "Banks"), Chemical Bank, as Managing Agent, 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 3.02(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 Borrower of the Credit
Agreement and the Notes are within the
 2

Borrower's corporate powers and have been duly authorized by all necessary
corporate action.

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

     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 any other person without our prior written consent.

                                   Very truly yours,
