lenders from time to time parties to this Agreement (collectively, the
"Lenders"), BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION and BANK OF
MONTREAL,  as Syndication Agents, THE INDUSTRIAL BANK OF JAPAN, LTD., LOS
ANGELES AGENCY as Co-Agent,and UNION BANK OF SWITZERLAND, NEW YORK BRANCH, as
Administrative Agent (the "Administrative Agent").

                             W I T N E S S E T H:

       WHEREAS, the Borrower has requested the Lenders severally to commit to
lend to the Borrower up to $350,000,000 on a revolving basis for general
corporate purposes;

       WHEREAS, the Lenders are willing to make such loans, on the terms and
conditions provided herein;

       NOW, THEREFORE, the parties agree as follows:


                                  ARTICLE I

                                 Definitions

       Section  1.01  DEFINITIONS.

       (a)     TERMS GENERALLY.  The definitions ascribed to terms in this
Agreement apply equally to both the singular and plural forms of such terms. 
Whenever the context may require, any pronoun shall be deemed to include the
corresponding masculine, feminine and neuter forms.  The words "include",
"includes" and "including" shall be interpreted as if followed by the phrase
"without limitation".  The phrase "individually or in the aggregate" shall be
deemed general in scope and not to refer to any specific Section or clause of
this Agreement.  All references herein to Articles, Sections, Exhibits and
Schedules shall be deemed references to Articles and Sections of, and Exhibits
and Schedules to, this Agreement unless the context shall otherwise require. 
The table of contents, headings and captions herein shall not be given effect
in interpreting or construing the provisions of this Agreement.  Except as
otherwise expressly provided herein, all references to "dollars" or "$" shall
be deemed references to the lawful money of the United States of America.

       (b)     ACCOUNTING TERMS.  Except as otherwise expressly provided
herein, the term "consolidated" and all other terms of an accounting nature
shall be interpreted and construed in accordance with GAAP, as in effect from
time to time; PROVIDED, HOWEVER, that, for purposes of determining compliance
with any covenant set forth in Article VII, such terms shall be construed in
accordance with GAAP as in effect on the date of this Agreement, applied on a
basis consistent with the construction thereof applied in preparing the
Borrower's audited financial statements referred to in Section 5.01(k).  If
there shall occur a change in GAAP which but for the foregoing proviso would
affect the computation used to determine compliance with any covenant set




forth in Article VII, the Borrower and the Lenders agree to negotiate in good
faith in an effort to agree upon an amendment to this Agreement that will
permit compliance with such covenant to be determined by reference to GAAP as
so changed while affording the Lenders the protection intended to be afforded
by such covenant prior to such change (it being understood, however, that such
covenant shall remain in full force and effect in accordance with its existing
terms unless and until such amendment shall become effective).

       a particular Competitive Bid Rate but the amount of such Competitive Bid
       shall cause the total amount of Competitive Bids accepted by the
       Borrower to exceed the amount specified in the Borrowing Request, then
       the Borrower shall (notwithstanding the minimum bid acceptance amount
       required by clause (F) below) accept a portion of such Competitive Bid
       or Bids in an amount equal to the amount specified in the Borrowing
       Request less the amount of all other Competitive Bids at a lower
       Competitive Bid Rate accepted with respect to such Borrowing Request,
       which acceptance, in the case of multiple Competitive Bids at such
       Competitive Bid Rate, shall be made PRO RATA in accordance with the
       amount of each such Competitive Bid at such Competitive Bid Rate,

            (E)  if the Borrower shall accept Competitive Bids made at a
       particular Competitive Bid Rate but shall be restricted by other
       conditions hereof from borrowing the principal amount of Competitive
       Loans specified in such Borrowing Request in respect of which
       Competitive Bids at such Competitive Bid Rate have been made or if the
       Borrower shall accept Competitive Bids made at a particular Competitive
       Bid Rate but the aggregate amount of Competitive Bids made at such
       Competitive Bid Rate shall exceed the amount specified in the Borrowing
       Request, then the Borrower shall accept a PRO RATA portion of each
       Competitive Bid made at such Competitive Bid Rate aggregating the       
       
                                      -21-
  

       
       portion of Competitive Loans with respect to which Competitive Bids at
       such Competitive Bid Rate have been received; PROVIDED, HOWEVER, that if
       the principal amount of Competitive Loans to be so allocated is not
       sufficient to enable Competitive Loans to be so allocated to each such
       Lender in a principal amount equal to $5,000,000 or in integral
       multiples of $1,000,000 in excess thereof, in the case of Eurodollar
       Competitive Loans, or in a principal amount equal to $1,000,000 or in
       integral multiples of $100,000 in excess thereof, in the case of
       Absolute Rate Competitive Loans, the Borrower shall select the Lenders
       to be allocated such Competitive Loans in a principal amount equal to
       not less than $1,000,000 but may round up allocations to the next higher
       integral multiple of $100,000 if necessary, and 

            (F)  except as provided in clauses (D) and (E) above, no Competitive
       Bid shall be accepted for a Competitive Loan unless such Competitive
       Loan is in a principal amount equal to $5,000,000 or an integral
       multiple of $1,000,000 in excess thereof in the case of Eurodollar
       Competitive Loans, or in a principal amount equal to $1,000,000 or in
       integral multiples of $100,000 in excess thereof, in the case of
       Absolute Rate Competitive Loans.

       (e)  If the Borrower notifies the Administrative Agent that a Borrowing
Notice for Competitive Loans is cancelled, the Administrative Agent shall give
prompt notice thereof to the Lenders.

       (f)  If the Borrower accepts one or more Competitive Bids, the
Administrative Agent shall promptly give notice (i) to each Lender that
submitted a Competitive Bid of the date and aggregate amount of such
Competitive Loan(s), the Competitive Bid Rate therefor and whether or not any
Competitive Bid made by such Lender has been accepted by the Borrower, (ii) to
each Lender whose Competitive Bid, or any portion thereof, has been accepted
by the Borrower, of the principal amount of the Competitive Loan to be made by
such Lender and the date for repayment thereof, together with the Competitive
Rate or Competitive Margin, as applicable, and any other terms applicable to
such Competitive Loan and (iii) to each Lender of the principal amounts and
Competitive Bid Rates specified in each of the Competitive Bids submitted in
response to the related Borrowing Request.

       (g)  Following any acceptance by the Borrower and notification by the
Administrative Agent pursuant to Section 2.06(f), and upon satisfaction, or
waiver by the Lenders, of each of the applicable conditions precedent
contained in Article VI, (i) such Lenders shall disburse to the Borrower, on
the specified Borrowing Date, Competitive Loans in the aggregate principal
amount accepted by the Borrower, in immediately available funds, and (ii) the
Borrower shall deliver to each such Lender a duly executed Competitive Note
evidencing its Competitive Loan. 

       (h)  Nothing in this Section 2.06 shall be construed as a right of first
offer in favor of the Lenders or to otherwise limit the ability of the
Borrower to request and accept credit facilities from any Person (including
any Lender).       

                                      -22-
  


       (i)  Each Competitive Loan shall be repaid, together with all accrued
and unpaid interest thereon, on the applicable Maturity Date.


                                 ARTICLE III

                              Interest and Fees

       Section 3.01  INTEREST RATE DETERMINATION; CONVERSION.  (a) Except to
the extent that the Borrower shall request, in a Revolving Credit Request, in
a Conversion Request or in a written election pursuant to Section 3.03(b),
that Revolving Credit Loans (or portions thereof) bear interest as Eurodollar
Loans, Revolving Credit Loans shall bear interest as ABR Revolving Loans.

       (b)  The Borrower may request, by giving a Conversion Request to the
Administrative Agent, not later than 1:00 P.M., New York time on the third
Business Day prior to the requested Conversion Date, that all or portions of
the outstanding Revolving Credit Loans, in the aggregate principal amount of
$5,000,000 or in integral multiples of $1,000,000 in excess thereof, in the
case of Loans being converted to or continued as Eurodollar Revolving Loans,
and in the aggregate principal amount of $1,000,000 or in integral multiples
of $100,000 in excess thereof (or, if the aggregate principal amount of
outstanding Revolving Loans is less than $1,000,000, then all such lesser
amount), in the case of ABR Revolving Loans, bear interest from and after the
Conversion Date as either ABR Revolving Loans or Eurodollar Revolving Loans;
PROVIDED, HOWEVER, that during the continuance of any Default or Event of
Default that shall have occurred, no Loan (or portion thereof) may be
converted into Eurodollar Revolving Loans.  Upon receipt, the Administrative
Agent forthwith shall give notice to each Lender of the substance of each
Conversion Request.  Upon payment by the Borrower of the amounts, if any,
required by Section 4.03, on the Conversion Date the Loans or portions thereof
as to which the Conversion Request was made shall commence to accrue interest
in the manner selected by the Borrower therein.

       (c)  Competitive Loans shall bear interest as Absolute Rate Competitive
Loans or Eurodollar Competitive Loans as determined in accordance with Section
2.06.

       Section 3.02  INTEREST ON ABR REVOLVING LOANS.  Each ABR Revolving Loan
shall bear interest from the date made until the date repaid, or (if converted
into a Eurodollar Revolving Loan) to (but excluding) the first day of any
relevant Interest Period, as the case may be, payable in arrears on the last
day of each calendar quarter of each year, commencing with the first such date
after the Effective Date, and on the date such Loan is repaid, at a rate per
annum equal to the Alternate Base Rate in effect from time to time, which rate
shall change as and when said Alternate Base Rate shall change.

       Section 3.03  INTEREST ON EURODOLLAR LOANS.  (a)  Each Eurodollar Loan
shall bear interest from the date made until the date repaid or converted to
an ABR Revolving Loan, payable in arrears, with respect to Interest Periods of
three months or less, on the last day of such Interest Period, and with
respect to Interest Periods longer than three months, on the day which is

                                      -23-
  


three months after the commencement of such Interest Period and on the last
day of such Interest Period, at a rate per annum equal to the sum of (i) the
Applicable Margin, in the case of Eurodollar Revolving Loans, or the
Competitive Margin, in the case of Eurodollar Competitive Loans, and (ii)
LIBOR.

       (b)  Each Eurodollar Revolving Loan shall become an ABR Revolving Loan
at the end of the Interest Period therefor, unless (i) there shall not have
occurred and be continuing a Default or Event of Default and (ii) not later
than the third Business Day prior to the last day of such Interest Period,
(x) the Borrower shall have delivered to the Administrative Agent an
irrevocable written election of the subsequent Interest Period, in which case
such Eurodollar Revolving Loan shall remain outstanding as a Eurodollar
Revolving Loan, or (y) the Borrower shall have delivered to the Administrative
Agent a Conversion Request with respect thereto, in which case such Eurodollar
Revolving Loan shall be converted in accordance with Section 3.01(b).

       (c)  If, during any period, a Lender shall be required to maintain
reserves against "Eurocurrency Liabilities" in accordance with Federal Reserve
Board Regulation D (or any successor regulation), the Borrower shall pay
additional interest during such period on each outstanding Eurodollar Loan of
such Lender (contemporaneously with each interest payment due thereon
commencing with the first such payment due at least five Business Days after
receipt of the notice referred to in the next sentence) at a rate per annum up
to but not exceeding the marginal rate determined by the following formula:

                                    LIBOR             -  LIBOR.
                      ---------------------------------
                      1 - Eurodollar Reserve Percentage

Each Lender shall promptly notify the Borrower, with a copy to the
Administrative Agent, upon becoming aware that the Borrower may be required to
make a payment of additional interest to such Lender.  When requesting payment
pursuant to this Section 3.03(c), a Lender shall provide to the Borrower, with
a copy to the Administrative Agent, a certificate, signed by an officer of
such Lender setting forth, in reasonable detail, the basis of such claim, the
amount required to be paid by the Borrower to such Lender and the computations
made by such Lender to determine such amount.  Absent manifest error, such
certificate shall be binding as to the amounts of additional interest owing in
respect of such Lender's Eurodollar Loans.  Any Lender that gives notice under
this Section 3.03(c) shall promptly withdraw such notice (by written notice of
withdrawal given to the Administrative Agent and the Borrower) whenever such
Lender is no longer required to maintain such reserves or the circumstances
giving rise to such notice shall otherwise cease.  Notwithstanding the
foregoing, no Lender shall be entitled to request compensation under this
Section 3.03(c) with respect to any Eurodollar Competitive Loan if it shall
have had actual knowledge of the change giving rise to such request at the
time of submission of the relevant Competitive Bid, unless notice of such
Lender's entitlement to such compensation shall have been furnished to the
Borrower at or prior to such time.

       Section 3.04  INTEREST ON ABSOLUTE RATE COMPETITIVE LOANS.  Each
Absolute Rate Competitive Loan shall bear interest from the date of such Loan

                                      -24-
  


to (but excluding) its Maturity Date, payable in arrears on the date such Loan
is repaid, at a rate per annum equal to the Competitive Rate.

       Section 3.05  INTEREST ON OVERDUE AMOUNTS.  All overdue amounts
(including principal, interest and fees) hereunder, and, during the
continuance of any Event of Default that shall have occurred, each Loan, shall
bear interest, payable on demand, at a rate per annum equal to the sum of (i)
2% and (ii)  in the case of Eurodollar Loans, the rate then applicable until
the end of the current Interest Period therefor, and thereafter the rate of
interest applicable to ABR Revolving Loans, changing as and when such rate
shall change, and in the case of ABR Revolving Loans, the rate of interest
applicable thereto, changing as and when such rate shall change.

       Section 3.06  DAY COUNTS.  Interest on ABR Revolving Loans shall be
calculated on the basis of (a) a 365- or, if applicable, a 366-day year for
the actual number of days elapsed for so long as interest is determined
pursuant to clause (i) of the definition of "Alternate Base Rate" and (b) a
360-day year for the actual number of days elapsed for so long as interest is
determined based on clause (ii) of the definition of "Alternate Base Rate". 
Interest on all other Loans, and all fees shall be calculated on the basis of
a 360-day year for the actual number of days elapsed.

       Section 3.07  MAXIMUM INTEREST RATE.  (a)  Nothing in this Agreement
shall require the Borrower to pay interest at a rate exceeding the maximum
rate permitted by applicable law.  Neither this Section nor Section 11.01 is
intended to limit the rate of interest payable for the account of any Lender
to the maximum rate permitted by the laws of the State of New York (or any
other applicable law) if a higher rate is permitted with respect to such
Lender by supervening provisions of U.S. Federal law.

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

       (c)  If the amount of interest payable for the account of any Lender in
respect of any interest computation period is reduced pursuant to Sec-
tion 3.07(b) and the amount of interest payable for its account in respect of
any subsequent interest computation period would be less than the maximum
amount permitted by law to be charged by such Lender, then the amount of
interest payable for its account in respect of such subsequent interest
computation period shall be automatically increased to such maximum
permissible amount; PROVIDED that at no time shall the aggregate amount by
which interest paid for the account of any Lender has been increased pursuant
to this Section 3.07(c) exceed the aggregate amount by which interest paid for
its account has theretofore been reduced pursuant to Section 3.07(b).

       Section 3.08  COMMITMENT FEES.  The Borrower agrees to pay to the
Administrative Agent, for the account of each Lender, on the last day of each
calendar quarter of each year, commencing with the first such day after the
Effective Date (or such later date on which such Lender becomes a Lender), and

                                      -25-
  


on the Termination Date (or other date on which the Commitment shall
terminate) with respect to such Lender, a fee (the "Commitment Fee") computed
by applying (i) the applicable percentage per annum set forth below based on
the ratings of the Borrower's senior unsecured long-term debt on each day
during the then-ending quarter (or shorter period ending with the Termination
Date or any other date on which the Commitment of such Lender shall terminate)
to (ii) the amount of such Lender's Unused Commitment on such day:


                                             Commitment Fee
                                          Percentage Per Annum

                                  ARTICLE IV

                           Disbursement and Payment

       Section 4.01  DISBURSEMENT.  (a)  Each Loan shall be made by the
relevant Lender from such Lender's branch or affiliate identified as its
Applicable Lending Office.

       (b)  The failure of any Lender to make any Loan to be made by it on
the Borrowing Date therefor shall not relieve any other Lender of its
obligation to make its Loan or Loans on such date, but neither any Lender nor
the Administrative Agent shall be responsible for the failure of any other
Lender to make a Loan to be made by such other Lender.

       (c)  The Administrative Agent may, but shall not be required to,
advance on behalf of any Lender the amount of such Lender's Loan to be made on
a Borrowing Date, unless such Lender shall have notified the Administrative
Agent prior to such Borrowing Date that it does not intend to make such Loan

                                      -26-
  


on such date.  If the Administrative Agent makes any such advance, the
Administrative Agent shall be entitled to recover the amount so advanced on
demand from the Lender on whose behalf such advance was made and, if such
Lender does not pay the Administrative Agent the amount of such advance on
demand, the Borrower agrees promptly to repay such amount to the
Administrative Agent.  Until such amount is repaid to the Administrative Agent
by such Lender or the Borrower, such advance shall be deemed for all purposes
to be a Loan made on such Borrowing Date by the Administrative Agent.  The
Administrative Agent shall be entitled to recover from the Lender or the
Borrower, as the case may be, interest on the amount advanced by it for each
day from the Borrowing Date therefor until repaid to the Administrative Agent,
at a rate per annum equal to the Federal Funds Rate until the third Business
Day after the date of the advance and, thereafter, at the rate per annum equal
to the relevant rate on Loans made on the relevant Borrowing Date.

       Section 4.02  METHOD AND TIME OF PAYMENTS; SHARING AMONG LENDERS. 
(a)  All funds received by the Administrative Agent for the account of the
Lenders in respect of payments made by the Borrower under, or from any other
Person on account of, any Credit Document shall be distributed forthwith by
the Administrative Agent among the Lenders, in like funds as received, ratably
in proportion to their respective interests therein.  Each payment of
Commitment Fees and each reduction of the Total Commitment shall be apportioned
among the Lenders in proportion to each Lender's Pro Rata Share.

       (b)  All payments by the Borrower hereunder shall be made without
setoff or counterclaim to the Administrative Agent, for its account or for the
account of the Lender or Lenders entitled thereto, as the case may be, in
dollars and in immediately available funds at the office of the Administrative
Agent prior to 3:00 P.M., New York time, on the date when due.

       (c)  Whenever any payment from the Borrower shall be due on a day that
is not a Business Day, the date of payment thereof shall be extended to the
next succeeding Business Day.  If the date for any payment of principal is
extended by operation of law or otherwise, interest thereon shall be payable
for such extended time.

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

       (e)  If any Lender shall receive from the Borrower or any other Person
any amount owing under any Credit Document (whether received pursuant to the
exercise of any right of set-off, banker's lien, realization upon any security
held for or appropriated to such obligation or otherwise) other than in
proportion to such Lender's ratable share thereof, then such Lender shall

                                      -27-
  


purchase from each other Lender a participating interest in so much of the
other Lenders' Loans as shall be necessary in order that each Lender shall
share such payment with each of the other Lenders in proportion to each
Lender's ratable share; provided that nothing herein contained shall obligate
any Lender to apply any set-off, banker's lien or collateral security first to
the obligations of the Borrower hereunder if the Borrower is obligated to such
Lender pursuant to other loans or notes.  If any purchasing Lender shall be
required to return any excess payment received by it, such participation shall
be rescinded and the purchase price restored to the extent of such return, but
without interest.

       Section 4.03  COMPENSATION FOR LOSSES.  (a)  If (i) the Borrower makes
a prepayment, or a Conversion Date occurs, other than on the last day of the
relevant Interest Period, (ii) the Borrower revokes any Borrowing Request for
Eurodollar Revolving Loans, (iii) Eurodollar Revolving Loans (or portions
thereof) are converted into ABR Loans pursuant to Section 4.05 or (iv) Loans
(or portions thereof) shall become or be declared to be due prior to the
scheduled maturity thereof, then the Borrower shall pay to each Lender an
amount that will compensate such Lender for any loss (other than lost profit)
or premium or penalty incurred by such Lender as a result of such prepayment,
conversion, declaration or revocation in respect of funds obtained for the
purpose of making or maintaining such Lenders's Loans, or any portion thereof. 
Such compensation shall include an amount equal to the excess, if any, of (i)
the amount of interest which would have accrued on the amount so paid or
prepaid, or not borrowed or converted, for the period from the date of such
payment or prepayment or conversion or failure to borrow to the last day of
such Interest Period (or, in the case of a failure to borrow, the Interest
Period that would have commenced on the date of such failure to borrow) in
each case at the applicable rate of interest for such Loan provided for herein
(excluding, however, any Applicable Margin included therein) over (ii) the
amount of interest (as reasonably determined by such Lender) which would have
accrued to such Lender on such amount by placing such amount on deposit for a
comparable period with leading banks in the London interbank deposit market.

       (b)  In connection with a demand for payment pursuant to this Section
4.03, a Lender shall provide to the Borrower, with a copy to the
Administrative Agent, a certificate, signed by an officer of such Lender,
setting forth in reasonable detail the amount required to be paid by the
Borrower to such Lender and the computations made by such Lender to determine
such amount.  In the absence of manifest error, such certificate shall be
conclusive as to the amount so required to be paid.

       Section 4.04  WITHHOLDING AND ADDITIONAL COSTS.

       (a)  WITHHOLDING.  (i) To the extent permitted by law, all payments
under this Agreement and under the Notes (including payments of principal and
interest) shall be payable to each Lender free and clear of any and all
present and future taxes, levies, imposts, duties, deductions, withholdings,
fees, liabilities and similar charges other than Excluded Taxes (collectively,
"Taxes").  If any Taxes are required to be withheld or deducted from any
amount payable under this Agreement, then the amount payable under this
Agreement shall be increased to the amount which, after deduction from such
increased amount of all Taxes required to be withheld or deducted therefrom,
will yield to such Lender the amount stated to be payable under this
Agreement.  The Borrower shall also hold each Lender harmless and indemnify it

                                      -20-
  


for any stamp or other taxes with respect to the preparation, execution,
delivery, recording, performance or enforcement of the Credit Documents (all
of which shall be included within "Taxes").  If any of the Taxes specified in
this Section 4.04(a) are paid by any Lender, the Borrower shall, upon demand
of such Lender, promptly reimburse such Lender for such payments, together
with any interest, penalties and expenses incurred in connection therewith. 
The Borrower shall deliver to the Administrative Agent certificates or other
valid vouchers for all Taxes or other charges deducted from or paid with
respect to payments made by the Borrower hereunder.  Notwithstanding the
foregoing, the Borrower shall be entitled, to the extent required to do so by
law, to deduct or withhold (and shall not be required to make payments as
otherwise required by this Section 4.04 on account of such deductions or
withholdings) income or other similar taxes imposed by the United States of
America from interest, fees or other amounts payable hereunder for the account
of any Lender other than a Lender (A) that is a U.S. Person for U.S. federal
income tax purposes or (B) that has the Prescribed Forms on file with the
Borrower for the applicable year to the extent deduction or withholding of
such taxes is not required as a result of such filing of such Prescribed
Forms; provided that, if the Borrower shall so deduct or withhold any such
taxes, the Borrower shall provide a statement to the Administrative Agent and
such Lender, setting forth the amount of such taxes so deducted or withheld,
the applicable rate and any other information or documentation which such
Lender may reasonably request for assisting such Lender to obtain any
allowable credits or deductions for the taxes so deducted or withheld in the
jurisdiction or jurisdictions in which such Lender is subject to tax.

       (ii)  Each Lender that is not incorporated under the laws of the
United States of America or a state thereof shall deliver to the Borrower and
the Administrative Agent two duly completed copies of United States Internal
Revenue Service Form 1001 or 4224 (or any successor form or forms), certifying
in either case that such Lender is entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income
taxes ("Prescribed Forms").  Each Lender that so delivers such Prescribed
Forms further undertakes to deliver to the Borrower and the Administrative
Agent two additional copies of such Prescribed Forms on or before the date
that such Prescribed Forms expire or become obsolete or after the occurrence
of any event requiring a change in the most recent Prescribed Forms so
delivered by it, and such amendments thereto or extensions or renewals thereof
as may be reasonably requested by the Borrower or the Administrative Agent, in
each case certifying that such Lender is entitled to receive payments under
this Agreement without deduction or withholding of any United States federal
income taxes, unless an event (including without limitation any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such Prescribed Forms
inapplicable or which would prevent such Lender from duly completing and
delivering Prescribed Forms with respect to it and such Lender advises the
Borrower and the Administrative Agent that it is not capable of receiving
payments without any deduction or withholding of United States federal income
tax.  If any Lender that is not incorporated under the laws of the United
States of America or a state thereof fails to comply with the provisions of
this Section, the Borrower and/or the Administrative Agent, may, as required
by law, deduct and withhold federal income tax payments from payments to such
Lender under this Agreement.       

                                      -29-
  


       (b)  ADDITIONAL COSTS.  Subject to Sections 4.04(c), (d) and (e):

       (i) Without duplication of any amounts payable described in Section
  3.03(c) or 4.03(a), if after the date hereof, any change in any law or
  regulation or in the interpretation thereof by any court or administrative
  or Governmental Authority charged with the administration thereof or the
  enactment of any law or regulation shall either (1) impose, modify or deem
  applicable any reserve, special deposit or similar requirement against any
  Lender's Commitment or Loans or (2) impose on any Lender (or such Lender's
  Applicable Lending Office) any other condition regarding this Agreement,
  its Commitment or the Loans and the result of any event referred to in
  clause (1) or (2) shall be to increase the cost to such Lender (or such
  Lender's Applicable Lending Office) of maintaining its Commitment or any
  Eurodollar Loans or Absolute Rate Competitive Loans made by such Lender
  (which increase in cost shall be calculated in accordance with such
  Lender's reasonable averaging and attribution methods) by an amount which
  such Lender deems to be material, then, upon demand by such Lender, then
  the Borrower shall pay to such Lender, on demand, an amount equal to such
  increase in cost; and

       (ii) Without duplication of any amounts payable described in Section
  3.03(c) or 4.03(a), if any Lender shall have determined that the adoption
  of any applicable law, rule, regulation or guideline regarding capital
  adequacy, or any change therein, or any change in the interpretation or
  administration thereof by any Governmental Authority, central bank or
  comparable agency charged with the interpretation or administration
  thereof, (including any such adoption or change made prior to the date
  hereof but not effective until after the date hereof) or compliance by
  such Lender (or such Lender's Applicable Lending Office) with any request
  or directive regarding capital adequacy (whether or not having the force
  of law) of any such authority, central bank or comparable agency, has or
  would have the effect of reducing the rate of return on capital for such
  Lender (or such Lender's Applicable Lending Office) or any corporation
  controlling such Lender as a consequence of its obligations under this
  Agreement to a level below that which such Lender (or such Lender's
  Applicable Lending Office) or such corporation could have achieved but for
  such adoption, change or compliance (taking into consideration such
  Lender's (or such Lender's Applicable Lending Office) or such
  corporation's policies with respect to capital adequacy), then from time
  to time, upon demand by such Lender, then the Borrower shall pay to such
  Lender, on demand, such additional amount or amounts as will compensate
  such Lender (or such Lender's Applicable Lending Office) or such
  corporation for such reduction.

       (c)  LENDING OFFICE DESIGNATIONS.  Before making any demand for
payment pursuant to this Section 4.04, each Lender shall, if possible,
designate a different Applicable Lending Office if such designation will avoid
the need for giving such notice and will not, in the judgment of such Lender,
be otherwise disadvantageous to such Lender.

       (d)  CERTIFICATE, ETC.  In connection with any demand for payment
pursuant to this Section 4.04, a Lender shall provide to the Borrower, with a
copy to the Administrative Agent, a certificate, signed by an officer of such
Lender, setting forth in reasonable detail the basis for such demand, the
amount required to be paid by the Borrower to such Lender, the computations
made by such Lender to determine such amount and satisfaction of the

                                      -30-
  


conditions set forth in the next sentence.  In the absence of manifest error,
the certificate referred to above shall be conclusive as to the amount so
required to be paid.

       (e)  LIMITATIONS.  The Borrower shall not be obligated to compensate a
Lender for any amount under Section 4.04(b) (i) and (ii) arising or occurring
more than 90 days prior to the date on which an office of such Lender
primarily responsible for the administration of this Agreement obtains actual
knowledge that such Lender is entitled to such compensation or (ii) with
respect to any Competitive Loan if it shall have had actual knowledge of the
change giving rise to such request at the time of submission of the relevant
Competitive Bid, unless notice of such Lender's entitlement to such
compensation shall have been specified in such Lender's Competitive Bid.

       Section 4.05  FUNDING IMPRACTICABLE.  If at any time any Lender shall
have determined in good faith (which determination shall be conclusive) that
the making or maintenance of all or any part of such Lender's Eurodollar
Revolving Loans has been made impracticable or unlawful because of compliance
by such Lender in good faith with any law or guideline or interpretation or
administration thereof by any Governmental Authority charged with the inter-
pretation or administration thereof or with any request or directive of such
body (whether or not having the effect of law) or because U.S. dollar deposits
in the amount and requested maturity of such Eurodollar Revolving Loans are
not available to such Lender in the London Eurodollar interbank market, then
the Administrative Agent, upon notification to it of such determination by
such Lender, shall forthwith advise the other Lenders and the Borrower
thereof.  Upon such date as shall be specified in such notice and until such
time as the Administrative Agent, upon notification to it by such Lender,
shall notify the Borrower and the other Lenders that the circumstances
specified by it in such notice no longer apply, (i) notwithstanding any other
provision of this Agreement, such Eurodollar Revolving Loans shall, automati-
cally and without requirement of further notice, or any payment pursuant to
Section 4.03 or 4.04, by the Borrower, be converted to ABR Revolving Loans,
(ii) the obligation of such Lender to make or continue Eurodollar Revolving
Loans shall be suspended, and, if the Borrower shall request in a Borrowing
Request or Conversion Request that the Lenders make a Eurodollar Revolving
Loan, the Loan requested to be made by such Lender shall instead be made as an
ABR Revolving Loan and (iii) such Lender shall not submit Competitive Bids in
respect of requests for Eurodollar Competitive Loans.

       Section 4.06  EXPENSES; INDEMNITY.  (a) The Borrower agrees to pay all
out-of-pocket expenses incurred by the Administrative Agent or any Lender
(including reasonable fees and disbursements of counsel) in connection with
the enforcement of any provision of any Credit Document or any amendment or
supplement to this Agreement.

       (b)  The Borrower agrees to indemnify the Administrative Agent and
each of the Lenders and their respective directors, officers, employees and
agents (each, an "Indemnitee") against, and to hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses,
including counsel fees and expenses, incurred by or asserted against any
Indemnitee arising out of, in any way connected with, or as a result of
(i) the execution or delivery of any Credit Document or any agreement or
instrument contemplated by any Credit Document, the performance by the parties
thereto of their respective obligations under any Credit Document or the
consummation of the transactions contemplated by any Credit Document, (ii) the

                                      -31-
  


use of the proceeds of the Loans or (iii) any claim, litigation, investigation
or proceeding relating to any of the foregoing, whether or not any Indemnitee
is a party thereto; PROVIDED that such indemnity shall not, as to any Indemni-
tee, be available to the extent that such losses, claims, damages, liabilities
or related expenses are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Indemnitee.

       (c)  All amounts due under this Section 4.06 shall be payable in
immediately available funds upon written demand therefor.

       Section 4.07.  SURVIVAL.  The provisions of Sections 4.03, 4.04, 4.06
and 9.06, shall remain operative and in full force and effect regardless of
the expiration of the term of this Agreement, the consummation of the
transactions contemplated hereby, the repayment of any of the Loans, the
reduction or termination of any Commitments, the invalidity or
unenforceability of any term or provision of any Credit Document, or any
investigation made by or on behalf of the Lenders.

       Section 4.08.  SUBSTITUTION OF A LENDER.  Notwithstanding anything to
the contrary contained herein, if any Lender shall request compensation
pursuant to Section 4.04(b)(i) and (ii) in an aggregate amount in excess of
$25,000, then, in each case, the Borrower may require that such Lender
transfer all of its right, title and interest under this Agreement and such
Lender's Notes to one or more of the other Lenders or any other lender
identified by the Borrower and reasonably acceptable to the Administrative
Agent (a "Proposed Lender") which is willing to assume all of the obligations
of such Lender, for consideration equal to the outstanding principal amount of
such Lender's Loans, together with interest thereon to the date of such
transfer and all other amounts payable under the Credit Documents to such
Lender on or prior to the date of such transfer (including, without
limitation, any fees accrued hereunder and any amounts which would be payable
under Section 4.03 as if all of such Lender's Loans were being prepaid in full
on such date).  Subject to the execution and delivery of new notes, an
Assignment and Acceptance, and such other documents as such Lender may
reasonably require, such Proposed Lender shall be a "Lender" for all purposes
hereunder.  Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements of the Borrower contained in Sections 4.04
and 4.06 (without duplication of any payments made to such Lender by the
Borrower or the Proposed Lender) shall survive for the benefit of any Lender
replaced under this Section 4.08 with respect to the time prior to such
replacement.

 
                                  ARTICLE V

                        Representations and Warranties

       Section 5.01  REPRESENTATIONS AND WARRANTIES.  The Borrower represents
and warrants to the Administrative Agent and each Lender as follows:

       (a)  CORPORATE EXISTENCE. 

                                      -32-
  

            
            (i)  the Borrower and each of its Significant Subsidiaries has
       been duly incorporated and is validly existing and in good standing
       under the laws of its jurisdiction of incorporation;

            (ii)  the Borrower  and each of its Significant Subsidiaries has
       the corporate power and authority and all necessary governmental
       licenses, authorizations, consents and approvals material to the
       ownership of its assets and the carrying on of its business;

            (iii)  the Borrower has the power and authority and all 
       governmental licenses, authorizations, consents and approvals to
       execute, deliver and perform its obligations under this Agreement and
       the Notes; and

            (iv)  the Borrower is duly qualified as a foreign corporation,
       licensed and in good standing under the laws of each jurisdiction
       where its ownership, lease or operation of Property or the conduct of
       its business requires such qualification.

       (b)  CORPORATE AUTHORIZATION; NO CONTRAVENTION.  The execution, 
  delivery, and  performance by the Borrower of the Credit Documents have
  been duly authorized by all necessary corporate action and do not and will
  not:

            (i)  contravene the terms of the Borrower's articles of
       incorporation, bylaws or other organizational document;

            (ii)  conflict with or result in any breach or contravention of,
       or the creation of any Lien under, any indenture, agreement, lease,
       instrument, Contractual Obligation, injunction, order, decree or
       undertaking to which the Borrower is a party or by which it is bound;
       or

            (iii)  violate any Requirement of Law.

       (c)  GOVERNMENTAL AUTHORIZATION.  The CPUC has duly issued an order
  which sets forth any and all CPUC approvals and authorizations required
  for the Borrower to enter into the Credit Documents and to take all
  actions contemplated hereby or in connection herewith, and such order
  remains in full force and effect in the form issued, and no other consent,
  approval, authorization or order of any Governmental Authority is required
  for due execution, delivery and performance by the Borrower of the Credit
  Documents.

       (d)  BINDING EFFECT.  This Agreement  is, and the Notes when delivered
  hereunder will be legal, valid and binding obligations of the Borrower
  enforceable against the Borrower in accordance with their respective terms
  subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
  moratorium or similar laws of general applicability relating to or
  affecting creditors' rights and to general equity principles.

       (e)  LITIGATION.  There are no actions, suits, proceedings, claims or
  disputes pending, or to the best knowledge of the Borrower, threatened at
  law, in equity, in arbitration or before any Governmental Authority, against

                                      -33-
  


  the Borrower, or its Subsidiaries or any of their respective Properties which 
  (i) purport to affect or pertain to this Agreement, or any of the transactions
  contemplated hereby; or (ii) if determined adversely to the Borrower, or its 
  Subsidiaries, might have a Material Adverse Effect.  No injunction, writ, 
  temporary restraining order or any order of any nature has been issued by any
  court or other Governmental Authority purporting to enjoin or restrain the 
  execution, delivery and performance of any Credit Document, or directing that
  the transactions provided for herein not be consummated as herein provided.

       (f)  NO DEFAULT.  No Default or Event of Default exists or would
  result from the incurring of the Obligations by the Borrower under this
  Agreement.  Neither the Borrower, nor any of its Significant Subsidiaries,
  is in default under or with respect to any Contractual Obligation which,
  individually or together with all such defaults, would have a Material
  Adverse Effect.

       (g)  ERISA COMPLIANCE.  

            (i) Each Qualified Plan is in compliance in all material respects
       with the applicable provisions of ERISA, the Code and other federal or
       state law, including all requirements under the Code or ERISA for
       filing reports (which are true and correct in all material respects as
       of the date filed), and to the best knowledge of the Borrower,
       benefits have been paid in accordance with the provisions of such
       Plan.

            (ii) Each Qualified Plan has been determined by the IRS to qualify
       under Section 401 of the Code, the IRS has not determined that any
       amendment to any Qualified Plan does not qualify under Section 401 of
       the Code, and the trusts created thereunder have been determined to be
       exempt from tax under the provisions of Section 501 of the Code, and
       to the best knowledge of the Borrower nothing has occurred which would
       cause the loss of such qualification or tax-exempt status.

            (iii) There is no outstanding liability under Title IV of ERISA
       with respect to any Plan maintained or sponsored by the Borrower or
       any ERISA Affiliate (as to which the Borrower is or may be liable),
       nor with respect to any Plan to which the Borrower or any ERISA
       Affiliate (wherein the Borrower is or may be liable) contributes or is
       obligated to contribute.

            (iv) None of the Qualified Plans subject to Title IV of ERISA has
       any Unfunded Pension Liability as to which the Borrower is or may be
       liable.

            (v) No ERISA Event has occurred or is reasonably expected to occur
       with respect to any Plan maintained or sponsored by the Borrower or to
       which the Borrower is obligated to contribute.            
       
                                      -34-
  

       
            (vi) There are no pending or, to the best knowledge of the
       Borrower, threatened claims, actions or lawsuits, other than routine
       claims for benefits in the usual and ordinary course, asserted or
       instituted against (i) any Plan maintained or sponsored by the
       Borrower or its assets, (ii) any member of the Controlled Group with
       respect to any Qualified Plan of the Company, or (iii) any fiduciary
       with respect to any Plan for which the Borrower may be directly or
       indirectly liable, through indemnification obligations or otherwise
       which would be reasonably likely to have a Material Adverse Effect.

            (vii) The Borrower has not incurred nor reasonably expects to
       incur (i) any liability (and no event has occurred which, with the
       giving of notice under Section 4219 of ERISA, would result in such
       liability) under Section 4201 or 4243 of ERISA with respect to a
       Multiemployer Plan or (ii) any liability under Title IV of ERISA
       (other than premiums due and not delinquent under Section 4007 of
       ERISA) with respect to a Plan.

            (viii) The Borrower has not transferred any Unfunded Pension
       Liability outside of the Controlled Group or otherwise engaged in a
       transaction that could be subject to Section 4069 or 4212(c) of ERISA.

            (ix) The Borrower has not engaged, directly or indirectly, in a
       non-exempt prohibited transaction (as defined in Section 4975 of the
       Code or Section 406 of ERISA) in connection with any Plan which would
       have a Material Adverse Effect. 

       (h)  USE OF PROCEEDS; MARGIN REGULATIONS.  No Loans will be used,
  directly or indirectly, (i) to purchase or carry Margin Stock or (ii) to
  repay or otherwise refinance indebtedness of the Borrower or others
  incurred to purchase or carry Margin Stock or (iii) to extend credit for
  the purpose of purchasing or carrying any Margin Stock.  No Loan will be
  used to acquire any security in any transaction which is subject to
  Sections 13 or 14 of the Securities Exchange Act of 1934.

       (i)  TITLE TO PROPERTIES.  The Borrower and each of its Significant
  Subsidiaries has sufficient and legal title in fee simple to or valid
  leasehold interest in all its Property, except for such defects in title
  as could not, individually or in the aggregate, have a Material Adverse
  Effect.  Such Property is free and clear of all Liens or rights of others,
  except Permitted Liens.

       (j)  TAXES.  The Borrower and its Subsidiaries have filed all federal
  and other material tax returns and reports required to be filed and have
  paid all federal and other material taxes, assessments, fees and other
  governmental charges levied or imposed upon them or their Properties,
  income or assets otherwise due and payable except (a) those which are
  being contested in good faith by appropriate proceedings and for which
  adequate reserves have been provided in accordance with GAAP and no Notice
  of Lien has been filed or recorded, and (b) those levied or imposed on
  Subsidiaries other than Significant Subsidiaries the nonpayment of which
  would not, in the aggregate, have a Material Adverse Effect.  To the best
  knowledge of the Borrower, there is no proposed tax assessment against the
  Borrower or any of its Subsidiaries which would, if the assessment were
  made, have a Material Adverse Effect.       
  
                                      -35-
  

  
       (k)  FINANCIAL CONDITION.

       December 31, 1996, and the unaudited consolidated balance sheets of
       the Borrower as of March 31, 1997, and the related consolidated
       statements of income, changes in shareholders' equity and cash flows
       for, each of the respective periods then ended, copies of which have
       been furnished to the Administrative Agent and the Lenders, fairly
       present the consolidated financial condition of the Borrower and its
       consolidated Subsidiaries as of, and the results of its operations and
       cash flows for, each of the respective periods then ended, applied on
       a consistent basis.  Such financial statements were prepared in
       accordance with GAAP consistently applied throughout the period
       covered thereby, are complete and accurate, and show all material
       indebtedness and other liabilities of the Borrower and its
       consolidated Subsidiaries as of the date thereof (including
       liabilities for taxes and material commitments).

            (ii)  The unaudited unconsolidated balance sheets of the Borrower
       as of December 31, 1996, and as of March 31, 1997 and the related
       unconsolidated statements of income, changes in shareholders' equity
       and cash flows for the period then ended, copies of which have been
       furnished to the Administrative Agent and the Lenders, fairly present
       the financial position of the Borrower as of, and the results of its
       operations and cash flows for, each of the respective periods then
       ended, applied on a consistent basis.

       (l)  ENVIRONMENTAL MATTERS. 

            (i)  The operations of the Borrower and each of its Subsidiaries
       comply with all Environmental Laws except where such noncompliance
       would not have a Material Adverse Effect.

            (ii)  The Borrower and each of its Subsidiaries have obtained all
       licenses, permits, authorizations and registrations required under any
       Environmental Law ("Environmental Permits") necessary for its
       operations, and all such Environmental Permits are in good standing,
       and the Borrower and each of its Subsidiaries are in compliance with
       all terms and conditions of such Environmental Permits, except where
       the failure so to obtain, be in good standing or  be in compliance
       would not have a Material  Adverse Effect.

            (iii)  None of the Borrower, any of its Subsidiaries or any of
       their present Property or operations is subject to any outstanding
       written order from or agreement with any Governmental Authority or
       other Person, nor subject to any judicial or docketed administrative
       proceeding, respecting any Environmental Law, Environmental Claim or
       Hazardous Material which would have a Material Adverse Effect.         
       
                                      -30-
  

       
            (iv)  There are no conditions or circumstances which may give rise
       to any Environmental Claim arising from the operations of the Borrower
       or its Subsidiaries which would have a Material Adverse Effect. 
       Without limiting the generality of the foregoing (i) neither the
       Borrower nor any of its Subsidiaries has any underground storage tanks
       (x) that are not properly registered or permitted under applicable
       Environmental Laws or (y) that are leaking or disposing of Hazardous
       Materials off-site and (ii) the Borrower and its Subsidiaries have
       notified all of their employees of the existence, if any, of any
       health hazard arising from the conditions of their employment and have
       met all notification requirements under Title III of CERCLA or any
       other Environmental Law, except where the failure to so notify would
       not, in the aggregate, have a Material Adverse Effect.

       (m)  REGULATED ENTITIES.  Neither the Borrower nor any Person
  controlling the Borrower is (a) an "Investment Company" within the meaning
  of the Investment Company Act of 1940; or (b) subject to regulation under
  the Public Utility Holding Company Act of 1935, the Federal Power Act, the
  Interstate Commerce Act or any regulation thereunder limiting its ability
  to incur Debt.

       (n)  LABOR RELATIONS.  There are no strikes, lockouts or other labor
  disputes against the Borrower or any of its Subsidiaries or, to the best
  of the Borrower's knowledge, threatened against or affecting the Borrower
  or any of its Subsidiaries which would have a Material Adverse Effect, and
  no significant unfair labor practice complaint is pending against the
  Borrower or any of its Subsidiaries or, to the best knowledge of the
  Borrower, threatened against any of them before any Governmental Authority
  which would have a Material Adverse Effect.

       (o)  INSURANCE.  The Properties of the Borrower and its Significant
  Subsidiaries are insured with financially sound and reputable insurance
  companies, in such amounts, with such deductibles and covering such risks
  as is customarily carried by companies engaged in similar businesses and
  owning similar Properties in localities where the Borrower or such
  Significant Subsidiary operates.

       (p)  FULL DISCLOSURE.  None of the representations or warranties made
  by the Borrower in this Agreement as of the date of such representations
  and warranties, and none of the statements contained in any certificate
  furnished by or on behalf of the Borrower in connection with this
  Agreement contains any untrue statement of a material fact or omits any
  material fact required to be stated therein or necessary to make the
  statements made therein, in light of the circumstances under which they
  are made, not misleading.

       (q)  COMPLIANCE WITH APPLICABLE LAWS.  Neither the Borrower nor any
  Subsidiary is in default with respect to any judgment, order, writ,
  injunction, decree or decision of any Governmental Authority which default
  would have a Material Adverse Effect.  The Borrower and each Subsidiary is
  complying in all material respects with all applicable statutes and
  regulations, including ERISA and applicable occupational, safety and
  health and other labor laws, of all Governmental Authorities, a violation
  of which would have a Material Adverse Effect.       
  
                                      -37-
  

  
       (r)  RANKING.  Obligations of the Borrower hereunder and under the
  Notes will rank senior to or PARI PASSU with all other Unsecured Debt of
  the Borrower.

       Section 5.02  SURVIVAL.  All representations and warranties made by
the Borrower in this Agreement, and in the certificates or other instruments
prepared or delivered in connection with or pursuant to this Agreement, shall
(i) be considered to have been relied upon by the Lenders, (ii) survive the

  liability (for additional taxes, to Plan  participants, or otherwise) in

                                  ARTICLE IX

                           The Administrative Agent

          Section 9.01  THE AGENCY.  Each Lender appoints Union Bank of
Switzerland, New York Branch, as its agent hereunder and irrevocably
authorizes the Administrative Agent to take such action on its behalf and to
exercise such powers hereunder and thereunder as are specifically delegated to
the Administrative Agent by the terms hereof and thereof, together with such
powers as are reasonably incidental thereto, and the Administrative Agent

                                     -48-


hereby accepts such appointment subject to the terms hereof.  The relationship
between the Administrative Agent and the Lenders shall be that of agent and
principal only and nothing herein shall be construed to constitute the
Administrative Agent a trustee or fiduciary for any Lender nor to impose on
the Administrative Agent duties or obligations other than those expressly
provided for herein.

          Section 9.02  THE ADMINISTRATIVE AGENT'S DUTIES.  The Administrative
Agent shall promptly forward to each Lender copies, or notify each Lender as
to the contents, of all notices received from the Borrower pursuant to the
terms of this Agreement and, in the event that the Borrower fails to pay when
due the principal of or interest on any Loan, the Administrative Agent shall
promptly give notice thereof to the Lenders.  As to any other matter not
expressly provided for herein, the Administrative Agent shall have no duty to
act or refrain from acting with respect to the Borrower, except upon the
instructions of the Required Lenders.  The Administrative Agent shall not be
bound by any waiver, amendment, supplement, or modification of this Agreement
which affects its duties hereunder, unless it shall have given its prior
written consent thereto.  The Administrative Agent shall have no duty to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, covenants or agreements binding on the Borrower pursuant to this
Agreement nor shall the Administrative Agent be deemed to have knowledge of
the occurrence of any Default or Event of Default (other than a failure of the
Borrower to pay when due the principal or interest on any Loan), unless it
shall have received written notice from the Borrower or a Lender specifying
such Default or Event of Default and stating that such notice is a "Notice of
Default".

          Section 9.03  LIMITATION OF LIABILITIES.  Each of the Lenders and
the Borrower agree that (i) neither the Administrative Agent nor any of its
officers or employees shall be liable for any action taken or omitted to be
taken by any of them hereunder except for its or their own gross negligence or
wilful misconduct, (ii) neither the Administrative Agent nor any of its
officers or employees shall be liable for any action taken or omitted to be
taken by any of them in good faith in reliance upon the advice of counsel,
independent public accountants or other experts selected by the Administrative
Agent, and (iii) the Administrative Agent shall be entitled to rely upon any
notice, consent, certificate, statement or other document believed by it to be
genuine and correct and to have been signed and/or sent by the proper Persons.

          Section 9.04  THE ADMINISTRATIVE AGENT AS A LENDER.  The
Administrative Agent may, without any liability to account, maintain deposits
or credit balances for, invest in, lend money to and generally engage in any
kind of banking business with the Borrower or any Subsidiary or Affiliate of
the Borrower without any duty to account therefor to the other Lenders.

          Section 9.05  LENDER CREDIT DECISION.  Neither the Administrative
Agent, nor any of its Affiliates, officers or employees has any responsibility
for, gives any guaranty in respect of, nor makes any representation to the
Lenders as to, (i) the condition, financial or otherwise, of the Borrower or
any Subsidiary thereof or the truth of any representation or warranty given or
made in this Agreement, or in connection herewith or therewith or (ii) the
validity, execution, sufficiency, effectiveness, construction, adequacy,
enforceability or value of this Agreement or any other document or instrument
related hereto.  Except as specifically provided herein, neither the
Administrative Agent nor any of its Affiliates, officers or employees shall
have any duty or responsibility, either initially or on a continuing basis, to
provide any Lender with any credit or other information with respect to the

                                     -49-


operations, business, property, condition or creditworthiness of the Borrower
or any of its Subsidiaries, whether such information comes into the
Administrative Agent's possession on or before the date hereof or at any time
thereafter.  Each Lender acknowledges that (i) it has, independently and
without reliance upon the Administrative Agent or any other Lender, based on
such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and (ii) all
information reviewed by it in its credit analysis or otherwise in connection
herewith has been provided solely by or on behalf of the Borrower, and the
Administrative Agent has no responsibility for such information.  Each Lender
also acknowledges that it will independently and without reliance upon the
Administrative Agent or any other Lender, 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 action under any Credit Document.

          Section 9.06  INDEMNIFICATION.  Each Lender agrees to indemnify the
Administrative Agent, to the extent not reimbursed by the Borrower, ratably in
proportion to its Commitment (as of the time of the incurrence of the
liability being indemnified against), from and against any and all
liabilities, obligations, losses, claims, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against the
Administrative Agent in any way relating to or arising out of this Agreement,
or any action taken or omitted to be taken by the Administrative Agent
hereunder; provided, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the gross negligence or
wilful misconduct of the Administrative Agent or any of its officers or
employees.  Without limiting the foregoing, each Lender agrees to reimburse
the Administrative Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including fees and disbursements of counsel incurred
by the Administrative Agent in connection with the preparation, execution or
enforcement of, or legal advice in respect of rights or responsibilities
under, any Credit Document or any amendments or supplements thereto, to the
extent that the Administrative Agent is not reimbursed for such expenses by
the Borrower.  Except for action expressly required of the Administrative
Agent hereunder, the Administrative Agent shall in all cases by fully
justified in failing or refusing to act hereunder unless it shall receive
further assurances to its satisfaction from the Lenders of their
indemnification obligations under this Section 9.06 against any and all
liability and expense that may be incurred by it by reason of taking or
continuing to take any such action.

          Section 9.07  SUCCESSOR ADMINISTRATIVE AGENT.  The Administrative
Agent may resign at any time by giving written notice thereof to the Lenders
and the Borrower.  Upon any such resignation, the Required Lenders shall have
the right to appoint a successor Administrative Agent.  If no successor
Administrative Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within 30 days after the resigning
Administrative Agent's giving of notice of resignation, the resigning
Administrative Agent may appoint a successor Administrative 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 $250,000,000.  Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the resigned

                                     -50-


Administrative Agent, and the resigned Administrative Agent shall be
discharged from its duties and obligations under this Agreement.  After any
Administrative Agent's resignation, the provisions of this Article IX shall
continue to inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.


                                  ARTICLE X

                         Evidence of Loans; Transfers

          Section 10.01  EVIDENCE OF LOANS.   (a)  REVOLVING CREDIT NOTES. 
The Borrower's obligation to repay the Revolving Credit Loans shall be
evidenced by Revolving Credit Notes, one such payable to the order of each
Lender.  The Revolving Credit Note of each Lender shall (i) be in the
principal amount of such Lender's Commitment, (ii) be dated the Effective Date
and (iii) be stated to mature on the Termination Date and bear interest from
its date until maturity on the principal balance (from time to time
outstanding thereunder) payable at the rates and in the manner provided
herein.  Each Lender is authorized to indicate upon the grid attached to its
Revolving Credit Note all Revolving Credit Loans made by it pursuant to this
Agreement, interest elections and payments of principal and interest thereon. 
Such notations shall be presumptive as to the aggregate unpaid principal
amount of all Revolving Credit Loans made by such Lender, and interest due
thereon, but the failure by any Lender to make such notations or the
inaccuracy or incompleteness of any such notations shall not affect the
obligations of the Borrower hereunder or under the Revolving Credit Notes.

          (b)  COMPETITIVE NOTES.  The Borrower's obligation to repay the
Competitive Loans shall be evidenced by Competitive Notes payable to the order
of the Lenders.  Each Competitive Note shall be payable to the Lender making
the Competitive Loan evidenced thereby, shall be in the principal amount of
such Competitive Loan, shall be dated the Borrowing Date for such Competitive
Loan and shall be stated to mature on the applicable Maturity Date and bear
interest from its date until maturity on the principal amount of such
Competitive Loan payable at the rates and in the manner provided herein.

          Section 10.02  PARTICIPATIONS.  Any Lender may at any time grant to
one or more financial 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 Lender of a participating interest to a Participant, whether
or not upon notice to the Borrower and the Administrative Agent, such Lender
shall remain responsible for the performance of its obligations hereunder,
and, except to the extent such participating interest has been granted
pursuant to Section 4.02(e), the Borrower and the Administrative Agent shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement.  Any agreement pursuant
to which any Lender may grant such a participating interest shall provide that
such Lender shall retain the sole right and responsibility to enforce the
obligations of the Borrower hereunder including the right to approve any
amendment, modification or waiver of any provision of this Agreement;
PROVIDED, that such participation agreement may provide that such Lender will
not agree to any modification, amendment or waiver of this Agreement described
in clauses (i) through (vi), inclusive, of Section 11.06 without the consent
of the Participant.

                                     -51-


          Section 10.03  ASSIGNMENTS.  (a)  Any Lender may at any time assign
to one or more financial institutions (each an "Assignee") all, or a
proportionate part of all, of its rights and obligations under this Agreement,
and such Assignee shall assume such rights and obligations, pursuant to an
instrument, in substantially the form of EXHIBIT F (an "Assignment and
Acceptance"), executed by such Assignee and such transferring Lender, with
(and subject to) the signed consent of the Borrower and the Administrative
Agent (which consent shall not be unreasonably withheld); PROVIDED, that the
foregoing consent requirement shall not be applicable in the case of an
assignment or other transfer by any Lender to an affiliate of such Lender, to
another Lender or to a Federal Reserve Bank.  Upon execution and delivery of
an Assignment and Acceptance and payment by such Assignee to such transferring
Lender of an amount equal to the purchase price agreed between such
transferring Lender and such Assignee and payment by the transferring Lender
or the Assignee of an assignment fee of $2000 to the Administrative Agent,
such Assignee shall be a Lender party to this Agreement and shall have all the
rights and obligations of a Lender with a Commitment as set forth in such
Assignment and Acceptance, and the transferring Lender shall be released from
its obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required.

          (b)  No Assignee of any transferring Lender's rights shall be
entitled to receive any greater payment under Section 4.03 or 4.04 than such
Lender would have been entitled to receive with respect to the rights trans-
ferred, unless such transfer is made with the Borrower's prior written consent
or by reason of the provisions of Section 4.04(c) requiring such transferring
Lender to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such payment
did not exist.

          Section 10.04.  CERTAIN PLEDGES.  Notwithstanding any other
provision in this Agreement, any Lender may at any time create a security
interest in, or pledge, all or any portion of its rights under this Agreement
and any Note held by it in favor of any Federal Reserve Bank in accordance
with Federal Reserve Board Regulation A (or any successor provision) or U.S.
Treasury Regulation 31 C.F.R. Sec. 203.14 (or any successor provision), and such
Federal Reserve Bank may enforce such pledge or security interest in any
manner permitted under applicable law.

TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR

                                     -52-

Administrative Agent and the Lenders each hereby irrevocably submits to the
non-exclusive jurisdiction of any state or federal court in the Borough of

ing or judgment relating to or arising out of any Credit Document.  The
Borrower, the Administrative Agent and the Lenders each hereby irrevocably
consents to the jurisdiction of any such court in any such action and to the
laying of venue in the Borough of Manhattan, The City of New York.  The
Borrower, the Administrative Agent and the Lenders each hereby irrevocably
waives, to the fullest extent permitted by applicable law, any objection to
the laying of the venue of any such suit, action or proceeding brought in the
aforesaid courts and hereby irrevocably waives any claim that any such suit,
action or proceeding brought in any such court has been brought in an
inconvenient forum.

          Section 11.04  SET-OFF.  The Borrower hereby authorizes each Lender
(including each Lender in its capacity as a purchaser of a participation
interest pursuant to Section 4.02(e)) upon the occurrence of an Event of
Default and at any time and from time to time during the continuance thereof,
to the fullest extent permitted by law, to set-off and apply any and all
deposits (whether general or special, time or demand, provisional or final and
in whatever currency) at any time held, and other Indebtedness at any time
owing, by such Lender to or for the credit or the account of the Borrower
against any of the obligations of the Borrower, now or hereafter existing
under any Credit Document, held by such Lender, irrespective of whether such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured.  The rights of each Lender under this
Section 11.04 are in addition to other rights and remedies (including other
rights of set-off) which such Lender may have.  Any Lender exercising its
rights under this Section 11.04 shall give notice thereof to the Borrower and
the Administrative Agent concurrently with or prior to the exercise of such
rights; PROVIDED that failure to give such notice shall not affect the
validity of such exercise.

          Section 11.05  CONFIDENTIALITY.  The Lenders and the Administrative
Agent agree (on behalf of themselves and each of their Affiliates, directors,
officers, employees and representatives) to take normal and reasonable
precautions and exercise due care to maintain the confidentiality of all 
non-public information provided to them by the Borrower or any Subsidiary or by
the Administrative Agent on the Borrower's or any Subsidiary's behalf in
connection with this Agreement and neither the Administrative Agent, any
Lender, nor any of their Affiliates, directors, officers, employees and
representatives shall use any such information for any purpose or in any
manner other than pursuant to the terms contemplated by this Agreement, except
to the extent such information (a) was or becomes generally available to the
public other than as a result of a disclosure by the Administrative Agent or
any Lender, or (b) was or becomes available on a non-confidential basis from a
source other than the Borrower, provided that such source is not bound by a
confidentiality agreement with the Borrower known to the Administrative Agent
or affected Lender(s); PROVIDED that nothing herein shall limit the disclosure
of any such information (i) to the extent required by statute, rule,
regulation or judicial process; (ii) to counsel for any of the Lenders or the
Administrative Agent; (iii) to bank examiners, auditors or accountants;

enforcement of the Credit Documents or (vii) to any assignee or participant
(or prospective assignee or participant) so long as such assignee or
participant (or prospective assignee or participant)  first executes and
delivers to the respective Lender a Confidentiality Agreement, in
substantially the form of EXHIBIT G.

          Section 11.06  AMENDMENTS AND WAIVERS.  Any provision of this
Agreement may be amended, modified, supplemented or waived, but only by a
written amendment or supplement, or written waiver, signed by the Borrower and
either the Required Lenders (and, if the rights or duties of the
Administrative Agent are affected thereby, by the Administrative Agent), or
the Administrative Agent with the consent of the Required Lenders; PROVIDED,
HOWEVER, that no such amendment, modification, or waiver shall, unless signed
by all the Lenders, or by the Administrative Agent with the consent of all the
Lenders, (i) increase or decrease the Commitment of any Lender or subject any
Lender to any additional obligation, (ii) reduce the principal of or rate of
interest on any Loan or any fees hereunder, (iii) postpone any payment of
principal of or interest on any Loan or any fees hereunder, (iv) postpone any

Agreement, or (vi) amend, modify, supplement or waive the provisions of this
Section 11.06.  Except to the extent expressly set forth therein, any waiver
shall be effective only in the specific instance and for the specific purpose
for which such waiver is given.

          Section 11.07.  CUMULATIVE RIGHTS; NO WAIVER.  Each and every right
granted to the Administrative Agent and the Lenders hereunder or under any
other document delivered in connection herewith, or allowed them by law or
equity, shall be cumulative and not exclusive and may be exercised from time
to time.  No failure on the part of the Administrative Agent or any Lender to
exercise, and no delay in exercising, any right will operate as a waiver
thereof, nor will any single or partial exercise by the Administrative Agent
or any Lender of any right preclude any other or future exercise thereof or
the exercise of any other right.
