WAINOCO OIL CORPORATION AND SUBSIDIARIES
NOTES TO INTERIM FINANCIAL STATEMENTS
June 30, 1997
(Unaudited)

1.  Financial statement presentation and earnings per share

Financial statement presentation

    The condensed consolidated financial statements include the accounts of
Wainoco Oil Corporation, a Wyoming Corporation, and its wholly owned
subsidiaries, including Frontier Holdings Inc. ("Frontier" or the "Refinery"),
collectively referred to as Wainoco or the Company.  These financial statements
have been prepared by the registrant without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission (SEC) and include all
adjustments (comprised of only normal recurring adjustments) which are, in the
opinion of management, necessary for a fair presentation.  Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations, although Wainoco believes that
the disclosures are adequate to make the information presented not misleading.
It is suggested that the financial statements included herein be read in
conjunction with the financial statements and the notes thereto included in
Wainoco's annual report on Form 10-K for the year ended December 31, 1996.

    Wainoco conducts its refining operations in the Rocky Mountain region of the
United States.  The Company's Cheyenne, Wyoming Refinery purchases the crude oil
to be refined and markets the refined petroleum products produced, including
various grades of gasoline, diesel fuel, asphalt and petroleum coke. As
discussed in Note 4, on June 16, 1997, Wainoco completed the sale of all its
Canadian oil and gas properties.  Operating results for Wainoco's oil and gas
exploration and production segment have been presented as discontinued
operations in the accompanying statements of operations and all previously
reported results have been restated to this presentation.

Earnings per share

    Primary and fully diluted earnings per share have been computed on the
weighted average number of common shares outstanding and assume the exercise of
stock option shares for the six months ended June 30, 1997 and the three months
ended June 30, 1997 and 1996.  The effect of dilution for the fully diluted
computation was immaterial. No effect was given for the addition of dilutive
stock options for the six months ended June 30, 1996 as a loss was incurred.
The primary and fully diluted average shares outstanding for the six months and
three months ended June 30, 1997 were 27,336,847 and 27,415,191, and in 1996
were 27,256,002 and 27,330,233, respectively.

    In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("FAS") No. 128, Earnings Per Share, which
establishes new standards for computing and presenting earnings per share.  The
provisions of the statement are effective for fiscal years ending after December
31, 1997. If the provisions of FAS No. 128 had been adopted in 1997 and 1996,
basic and diluted earnings per share would not have been materially different
from primary and fully diluted earnings per share, respectively, as calculated
in accordance with Accounting Principles Board Opinion No. 15.

3.  Refining credit facility

    The Frontier revolving credit facility was amended in 1997 to extend the
maturity from April 2, 1998 to April 2, 1999.  No changes to the financial terms
of the credit facility were made.

4.  Sale of Canadian oil and gas operations

    On June 16, 1997, Wainoco completed the sale of all its Canadian oil and gas
properties to Numac Energy Inc. The transaction was initiated by the Company
through a negotiated bid process in order to maximize shareholder value.  The
oil and gas assets were located in British Columbia and Alberta and included
approximately 94 billion cubic feet of natural gas, 1.7 million barrels of oil,
condensate and natural gas liquids, 121,500 net undeveloped leasehold acres and
a significant amount of seismic data.  Additionally, value was received for
certain Canadian income tax pools of the Company.

    The contract purchase price of C$133.6 million was adjusted from the January
1, 1997 effective date of the sale to June 16, 1997.   Net proceeds after these
adjustments, transaction expenses and severance costs were approximately C$126.7
million (US$91.3 million) as of June 16, 1997.  As of June 30, 1997, $7.7
million of cash deposits are restricted until all Canadian tax reporting is
completed, which is expected to be within six months.

    A net gain of $23.3 million was realized on the transaction.  No Canadian
taxes are estimated to be payable due to available oil and gas deductions and
net operating loss carryforwards.  For U.S. federal income taxes, available net
operating loss carryforwards will be utilized to offset the gain;  however,
alternative minimum taxes of approximately $800,000 are estimated to be payable.

    The cumulative translation adjustment as of May 5, 1997 (the measurement
date of the sale) of $9.9 million was realized against income as a result of the
sale.  In prior periods, Wainoco had recognized the currency translation impact
of its Canadian operations as a direct reduction to shareholders' equity.
Consequently, the recognition of the cumulative translation adjustment in the
accompanying statements of operations has no affect on shareholders' equity.

    A net operating loss of $54,000 from Canadian operations from the
measurement date until June 16, 1997 was included in the gain calculation.  As
of June 30, 1997, the assets and liabilities of the Canadian operations retained
by Wainoco consist of the following (in thousands):

             Receivables                   $323
             Other Assets                   141

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS

                        RESULTS OF OPERATIONS
Six months ended June 30, 1997 compared with the same period in 1996

  The Company had net income for the six months ended June 30, 1997 of
$9,661,000, or $.35 per share, compared to a loss of $3,705,000 or $.14 per
share for the same period in 1996.  The 1997 results include a $23.3 million
gain on the sale of the Canadian oil and gas operations which closed on June 16,
1997 and the $9.9 million reduction to income in recognition of the cumulative
translation adjustment.  Refer to Note 4 to the financial statements for further
information on the sale.  Operating results for Wainoco's oil and gas
exploration and production segment have been presented as discontinued
operations in the accompanying statements of operations and all previously
reported results have been restated to this presentation.  Wainoco's primary
continuing operation is its Frontier refining operation in the Rocky Mountain
region of the United States.

  Operating income increased $551,000 in 1997 versus 1996 due to an increase in
the refined product spread and an increase in other income offset by higher
refining operating costs.  The refined product spread was $4.75 per bbl compared
to $4.66 per bbl in 1996.  The 1997 refined product spread benefited from better
light product margins and improved sweet/sour spread despite the first quarter
1997 inventory losses of approximately $4.0 million from a decline in crude
prices of more than $6 per bbl.  Inventories are recorded at the lower of cost
on a first in, first out (FIFO) basis or market.  Refined product revenues
increased $9.3 million or 5.3%.  The increase in refined product revenues
resulted from a $.65 per bbl increase in average product sales prices.  Refined
product sales volumes also increased 3% in 1997 over 1996 levels. Yields of
gasoline decreased 3%, while yields of distillate increased by 1% from the same
period in 1996.

  Other income increased $685,000 to $1,230,000 in 1997 versus 1996 due to
foreign currency transaction gains of $496,000 related to the Canadian sales
proceeds and higher processing fees.

  Refining operating costs increased $9.3 million or 6% over 1996 levels due to
an increase in material costs and refining operating expense.  Material costs
per bbl increased 3% or $.56 per bbl in 1997 due to higher oil prices and
inventory losses caused by the rapid decline in crude prices since year-end
1996.  The sweet/sour spread increased 33% to average $3.40 per bbl in the six
months of 1997 as Frontier contracted approximately 30,000 bpd of Wyoming and
Canadian sour crude oil for much of 1997 at a sweet/sour spread substantially
better than in 1996. Refining operating expense per bbl increased $.12 per bbl
to $3.33 per bbl in 1997 due to higher maintenance costs compared to 1996
operating expenses which were reduced by a $1.3 million settlement of repair
costs related to a 1995 pipeline gas explosion.

  Selling and general expenses increased $99,000 or 3% for the six months ended
June  30, 1997 reflecting increases in salaries and benefits.  The six months
ended June 30, 1996 included $240,000 of salary and salary-related expenses of
certain employees who were not retained subsequent to March 31, 1996 in
connection with the disposition of United States oil and gas operations in late
1995 and corporate reorganization in early 1996.

  Depreciation increased $63,000 or 1% in the 1997 six-month period as compared
to the same period in 1996, attributable to increases in capital investment.

  The interest expense increase of $504,000 or 6% in 1997 was attributable to
interest on higher borrowings during 1997 under the Frontier revolving credit
facility and more 12% senior notes outstanding during 1997 than 1996.  Average
debt for the six months increased from $152 million in 1996 to $161  million in
1997.

  Income from discontinued oil and gas operations includes Canadian oil and gas
operations through May 5, 1997 and both Canadian and United States oil and gas
operations for 1996.  Income from discontinued operations declined $240,000 to
$1,721,000 for the six months ended June 30, 1997 as compared to 1996,
consisting of a $601,000 increase in Canadian oil and gas income and a $841,000
decrease in United States oil and gas income.  The increase in Canadian oil and
gas income is due to higher oil and gas prices offset by declining volumes.  The
1996 discontinued earnings included $841,000 associated with the 1995
disposition of United States oil and gas operations, due to a reduction of
certain accruals.

Three months ended June 30, 1997 compared with the same period in 1996

  The Company had net income for the three months ended June 30, 1997 of
$18,140,000, or $.66 per share, compared to net income of $1,737,000, or $.06
per share, for the same period in 1996.  The 1997 results include a $23.3
million gain on the sale of the Canadian oil and gas operations which closed on
June 16, 1997 and the $9.9 million reduction to income in recognition of the
cumulative translation adjustment.  Refer to Note 4 to the financial statements
for further information on the sale.  Operating results for Wainoco's oil and
gas exploration and production segment have been presented as discontinued
operations in the accompanying statements of operations and all previous
reported results have been restated to this presentation.  Wainoco's primary
continuing operation is its Frontier refining operation in the Rocky Mountain
region of the United States.

  Operating income increased $3,124,000 to $9,045,000 in 1997 versus 1996 due to
an increase in the refined product spread to $6.18 per bbl from $5.77 per bbl,
an increase in other income and reduced refining operating expense.  The
improvement in the refined product spread was due to better gasoline margins,
the increase sweet/sour spread for crude oil and better by-product margins due
to lower crude oil prices.  Despite the improved refined product spread and
increased sales volumes, refined product revenues decreased as product and crude
price levels were lower. Refined product sales prices declined $1.81 per bbl in
1997 to an average $25.06 per bbl.  Refined product sales volumes increased
approximately 2% in 1997 from 1996 levels, primarily asphalt and other
by-product sales.  Yields of gasoline and diesel each declined 3% from 1996
levels while asphalt and other by-product yields increased.  The crude charge
rate was unchanged, yet the percentage of sour crude usage increased to 92% of
total crude oil charge in 1997 versus 84% in 1996.  The increased sour crude
usage, while more profitable, resulted in lesser gasoline and diesel yields and
increased by-product yields.

  Other income increased $589,000 to $872,000 in 1997 versus 1996 due to foreign
currency transaction gains of $496,000 related to the Canadian sales proceeds
and higher processing fees.

  Refining operating costs decreased $7,467,000 or 8% over 1996 levels primarily
as a result of a decrease in material costs and a decrease in refining operating
expense.  Material costs per bbl decreased approximately  11% or $2.22 per bbl
in 1997 due to lower oil prices.  The sweet/sour spread increased 29% to average
$3.32 per bbl in 1997, as Frontier has contracted approximately 30,000 bpd of
Wyoming and Canadian sour crude oil for much of 1997 at a sweet/sour spread
substantially better than in 1996.  Refining operating expense decreased $.28
per bbl to $2.98 per bbl in 1997 due to reduced energy and turnaround costs
partially offset by higher maintenance costs.  The strike by approximately 150
union employees which commenced May 8, 1996 and settled July 29, 1996 did not
adversely impact 1996 operating costs.

  Selling and general expenses increased $352,000 to $1,785,000 for the three
months ended June 30, 1997, reflecting increases in salary and benefits and
other general expenses.

  The interest expense increase of $195,000 or 5% was attributable to higher
borrowings during 1997 under the refining revolving credit facility and more 12%
senior notes outstanding during 1997 than 1996.  Average debt for the three
months ended June 30, 1997 increased from $154 million in 1996 to $161 million
in 1997.

  Income from discontinued oil and gas operations includes Canadian oil and gas
operations from April 1, 1997 through May 5, 1997 and both Canadian and United
States oil and gas operations for the 1996 period.  Income from discontinued
operations declined $25,000 to $167,000 for the three months ended June 30, 1997
as compared to 1996, consisting of a $57,000 decrease in Canadian oil and gas
income and a $110,000 decrease in United States oil and gas income.  The
decrease in Canadian oil and gas income is due to only one month of income being
reported for 1997.  The 1996 discontinued earnings included $110,000 associated
with the 1995 disposition of United States oil and gas operations due to a
reduction of certain accruals.

LIQUIDITY AND CAPITAL RESOURCES

  On June 16, 1997, Wainoco completed the sale of its Canadian oil and gas
properties.  Net proceeds after purchase price adjustments, transaction expenses
and severance costs were approximately C$126.7 million (US$91.3 million).  The
Company intends to use the net proceeds from the disposition to repay $57.5
million principal amount of debt obligations of the Company.  The Company
expects to retire $7.5 million of 10 3/4% Subordinated Debentures in October
1997 and repay $50 million of 12% Senior Notes in the third quarter of 1997 at a
redemption price of 103.43%.  Based on the anticipated repayments, the Company
will recognize an extraordinary loss on debt extinguishment during the second
half of 1997 totaling approximately $2.7 million due to the redemption premium
of 103.43% on the 12% Senior Notes and reduction in debt issuance costs.  On
July 21, 1997, the Company initiated a tender offer for $91.4 million of its 12%
Senior Notes at a price of par as required by the Senior Note Indenture after a
material sale of assets.  The par tender offer will expire on August 20, 1997.
The ultimate amount of debt repayment in 1997 will depend upon the response to
the tender offer, the Company's market outlook and investment opportunities
available to Wainoco and could vary significantly.

  Commencing June 30, 1997, borrowings under the Frontier revolving credit
facility are reflected as current liabilities.  Prior to this, borrowings were
reflected as long-term debt because of available credit under the Canadian oil
and gas line of credit which was terminated upon the sale of the Canadian oil
and gas properties.

  During the first six months of 1997, $4,820,000 of cash flows were used in
operating activities.  In 1996, $7,313,000 of cash flows were used in operating
activities primarily for a Refinery inventory increase of $9,028,000. The
primary source of cash was net borrowings of $6,400,000 in 1997 and $7,600,000
in 1996 under the Frontier line of credit.  Proceeds on the resale of $2,000,000
of 12% Senior Notes in each of the years were used to finance operating and
investing activities.

  At June 30, 1997, the Company had $18,600,000 available under the Frontier
line of credit.  The Company had working capital of $83,731,000 at June 30,
1997, including sales proceeds, compared with $4,404,000 at June 30, 1996.

  Additions to property and equipment in the first six months decreased
$2,108,000 from the first six months in 1996.  In the first six months of 1997,
capital expenditures in Canada decreased approximately $1.9 million to $3.3
million, while expenditures at the Refinery decreased approximately $.2 million
to $2.3  million.  Investing activities include proceeds from the sale of the
Canadian oil and gas properties of $91.3 million for the six months ended June
30, 1997.  Capital expenditures of approximately $9.0 million are currently
planned for 1997, of which $4.4 million had been incurred as of June 30, 1997.
Capital expenditures of approximately $6.2 million are planned for the Refinery
in 1997.

                          COMMITMENTS
 
     Section 2.1  Commitments.
 
          (a)  Each Bank agrees severally, on the terms and
 conditions contained in this Agreement, to extend credit to the
 Borrower from time to time from the Closing Date to the Commit-
 ment Termination Date by making loans to the Borrower (the
 "Loans") pursuant to Section 2.4 and participating in letters of
 credit issued for the account of the Borrower (the "Letters of
 Credit") pursuant to Section 2.9, in an aggregate amount not to
 exceed at any time outstanding the amount set forth opposite such
 Bank's name on the signature pages hereof or, if such Bank has
 entered into one or more Assignments and Acceptances, set forth
 for such Bank in the Register maintained by the Agent pursuant to
 Section 9.8(c); provided, however, that the sum of (i) the
 aggregate principal amount of all Loans outstanding, (ii) the
 aggregate Letter of Credit Amount of all Letters of Credit
 outstanding and (iii) the aggregate amount of unreimbursed
 drawings under all Letters of Credit shall not exceed fifty
 million dollars ($50,000,000) at any time; provided further,
 however, that the sum of (i) the aggregate principal amount of
 all Loans outstanding, (ii) the Letter of Credit Usage and
 (iii) the aggregate amount of unreimbursed drawings under all
 Letters of Credit shall not exceed the Borrowing Base at any
 time; and provided further, however, that the aggregate principal
 amount of all Loans outstanding at any time shall not exceed
 $20,000,000 (said agreement by each Bank, subject to the
 foregoing provisos, herein called such Bank's "Commitment"). 
 Within the limits of each Bank's Commitment, the Borrower may
 borrow under Section 2.4, have Letters of Credit issued for the
 Borrower's account under Section 2.9, prepay Loans under
 Section 2.7(a), reborrow under Section 2.4, and have additional
 Letters of Credit issued for the Borrower's account under
 Section 2.9 after the expiration of previously issued Letters of
 Credit.
 
          (b)  Reduction of Commitments.  The Borrower shall have
 the right, upon at least seven (7) Business Days' notice to the
 Agent, to terminate in whole or reduce ratably in part the unused
 portions of the respective Commitments of the Banks; provided,
 however, that each partial reduction shall be in the aggregate
 amount of five million dollars ($5,000,000) or an integral
 multiple thereof.
 
     Section 2.2  Fees.
 
          (a)  The Borrower shall pay to the Agent for the
 account of the Banks, from June 30, 1997 to the Commitment
 Termination Date, a commitment fee at the rate of .375% per annum
 on the average daily amount by which fifty million dollars
 ($50,000,000) exceeds the sum of (i) the aggregate face amount of
 all Letters of Credit outstanding plus (ii) the aggregate amount
 of all Loans outstanding.  Such commitment fee shall be payable
 quarterly in arrears on the last Business Day of each March,
 June, September and December, commencing on September 30, 1997,
 and on the Commitment Termination Date.
 
          (b)  The Borrower shall pay to the Agent for its own
 account such fees as provided in the Agent's Fee Letter.
 
     Section 2.3  Mandatory Prepayment of Loans and Pledge of
 Cash Collateral.  If at any time (a) the sum of (i) the aggregate
 principal amount of all Loans outstanding, (ii) the aggregate
 Letter of Credit Amount of all Letters of Credit outstanding and
 (iii) the aggregate amount of unreimbursed drawings under all
 Letters of Credit exceeds (b) the aggregate Commitments, or if at
 any time (y) the sum of (i) the aggregate principal amount of all
 Loans outstanding, (ii) the Letter of Credit Usage and (iii) the
 aggregate amount of unreimbursed drawings under all Letters of
 Credit exceeds (z) the Borrowing Base, then, in either case, the
 Borrower shall immediately, without notice or request by the
 Agent or the Banks, prepay the Loans (together with accrued
 interest to the date of prepayment on the principal amount
 prepaid) and/or pledge additional cash collateral to the Agent to
 secure reimbursement of amounts available to be drawn under
 outstanding Letters of Credit, in an aggregate amount equal to
 such excess.
 
 A.  LOANS
 
     Section 2.4  Making Loans.
 
          (a)  Each Borrowing shall be made on notice, given
 (i) with respect to any Borrowing consisting of Reference Rate
 Loans, not later than 1:30 p.m., Los Angeles time, on the
 Business Day before the date of the proposed Borrowing and
 (ii) with respect to any Borrowing consisting of LIBOR Loans, not
 later than 11:00 a.m., Los Angeles time, on the third Business
 Day before the date of the proposed Borrowing, each such notice
 to be given by the Borrower to the Agent, which shall give each
 Bank prompt notice thereof by telecopier.  Each such notice of a
 Borrowing (a "Notice of Borrowing") shall be in writing, or by
 telephone confirmed promptly in writing, by an Authorized
 Officer, specifying (i) the requested date of such Borrowing
 (which shall be a Business Day), (ii) the requested Type of Loans
 making up such Borrowing, (iii) the requested aggregate amount of
 such Borrowing, (iv) in the case of a Borrowing consisting of
 LIBOR Loans, the requested initial Interest Period for such LIBOR
 Loans and (v) the fact that the statements set forth in Sec-
 tion 4.2(b) are true as of the date of such Borrowing.  Each Bank
 shall, before 11:00 a.m., Los Angeles time, on the date of such
 Borrowing, make available to the Agent at its address referred to
 in Section 9.2, in immediately available funds, such Bank's
 ratable portion of such Borrowing.  After the Agent's receipt of
 such funds and upon fulfillment of the applicable conditions set
 forth in Article 4, the Agent will make such funds available to
 the Borrower by crediting the Borrower's concentration account
 number 0880412175 at the Agent's aforesaid address.  Notwith-
 standing the provisions of the first sentence of this Section
 2.4(a), if the Borrower gives the Agent notice of a Borrowing
 consisting of Reference Rate Loans not later than 8:30 a.m., Los
 Angeles time, on the day of the proposed Borrowing, the Agent and
 the Banks will use their best efforts (but shall not be obligat-
 ed) to make such Reference Rate Loans available on the day on
 which such notice is given; provided, however, that the Agent and
 the Banks shall no longer be required to use their best efforts
 as described in this sentence if the Agent, at its sole option
 exercisable at any time, gives the Borrower notice of the same.
 
          (b)  Each Notice of Borrowing shall be irrevocable and
 binding on the Borrower.  The Borrower shall indemnify each Bank
 against any loss, cost or expense incurred by such Bank as a
 result of any failure to fulfill, on or before the date specified
 for such Borrowing in the related Notice of Borrowing, the
 applicable conditions set forth in Article 4, including any loss
 (including loss of anticipated profits), cost or expense incurred
 by reason of the liquidation or reemployment of deposits or other
 funds acquired by such Bank to fund the Loan to be made by such
 Bank as part of such Borrowing when such Loan, as a result of
 such failure, is not made on such date.
 
          (c)  Unless the Agent receives notice from a Bank
 before the date of any Borrowing that such Bank will not make
 available to the Agent such Bank's ratable portion of such
 Borrowing, the Agent may assume that such Bank has made such
 portion available to the Agent on the date of such Borrowing in
 accordance with Section 2.4(a), 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 has
 not made such ratable portion available to the Agent, such Bank
 and the Borrower severally agree to repay to the Agent forthwith
 on demand such corresponding amount, together with interest
 thereon, for each day from the date such amount is made available
 to the Borrower until the date such amount is repaid to the
 Agent, at (i) in the case of the Borrower, the interest rate
 applicable at the time to the Loans making up such Borrowing and
 (ii) in the case of such Bank, the Federal Funds Rate.  If such
 Bank repays to the Agent such corresponding amount, such amount
 so repaid shall constitute such Bank's Loan as part of such
 Borrowing for purposes of this Agreement.
 
          (d)  The failure of any Bank to make the Loan to be
 made by it as part of any Borrowing shall not relieve any other
 Bank of its obligation, if any, hereunder to make its Loan on the
 date of such Borrowing, but no Bank shall be responsible for the
 failure of any other Bank to make the Loan to be made by such
 other Bank on the date of any Borrowing.
 
     Section 2.5  Repayment.  The Borrower shall repay to the
 Agent for the account of the Banks the outstanding principal
 amount of the Loans on the Commitment Termination Date.
 
     Section 2.6  Interest.
 
          (a)  The Borrower shall pay interest on the unpaid
 principal amount of each Loan made by each Bank, from the date of
 such Loan until such principal amount has been paid in full,
 (i) during such periods as such Loan is a Reference Rate Loan, at
 a rate per annum equal at all times to the sum of the Reference
 Rate in effect from time to time plus 0.5% per annum, payable
 monthly in arrears on the last Business Day of each calendar
 month during such periods and on the Commitment Termination Date,
 and (ii) during such periods as such Loan is a LIBOR Loan, at a
 rate per annum equal at all times during each Interest Period for
 such Loan to the sum of the LIBOR Rate for such Interest Period
 for such Loan plus 1.75% per annum, payable on the last day of
 such Interest Period or, if such Interest Period is longer than
 90 days, on the day that is 90 days after the first day of such
 Interest Period and on the last day of such Interest Period.
 
          (b)  Any amount of principal of any Loan that is not
 paid when due (whether at stated maturity, by required prepay-
 ment, by acceleration or otherwise) shall bear interest, from the
 date on which such amount is due until such amount is paid in
 full, payable on demand, at a rate per annum (the "Default Rate")
 equal at all times to the sum of the interest rate applicable to
 such Loan at the time it became due plus 3.00% per annum.
 
          (c)  The Agent shall give prompt notice to the Borrower
 and the Banks of each applicable interest rate determined by the
 Agent for purposes of Section 2.6(a).
 
          (d)  If the Borrower fails to select the duration of
 any Interest Period for any LIBOR Loans in accordance with the
 provisions contained in the definition of "Interest Period" in
 Section 1.1, the Agent will forthwith so notify the Borrower and
 the Banks, and such Loans will automatically, on the last day of
 the then existing Interest Period therefor, Convert into
 Reference Rate Loans.
 
     Section 2.7  Prepayments.
 
          (a)  The Borrower may on any Business Day, in the case
 of Reference Rate Loans upon prior written notice not later than
 9:00 a.m., Los Angeles time, on the day of any prepayment of such
 Loans, and in the case of LIBOR Loans upon at least three
 (3) Business Days' prior written notice, to the Agent stating the
 proposed date and aggregate principal amount of the prepayment,
 and if such notice is given the Borrower shall, prepay the
 outstanding principal amounts of the Loans making up a Borrowing
 in whole or ratably in part, together, in the case of LIBOR
 Loans, with accrued interest to the date of such prepayment on
 the principal amount prepaid; provided, however, that any
 prepayment of LIBOR Loans shall be made on, and only on, the last
 day of an Interest Period for such Loans; and provided further,
 however, that each partial prepayment shall be in the aggregate
 principal amount of one hundred thousand dollars ($100,000) or an
 integral multiple thereof.
 
          (b)  If at any time the aggregate principal amount of
 all Loans outstanding exceeds $20,000,000, then the Borrower
 shall immediately, without notice or request by the Banks, prepay
 the outstanding principal amounts of the Loans making up one or
 more Borrowings in whole or ratably in part in the aggregate
 amount equal to such excess, together with accrued interest to
 the date of such prepayment on the principal amount prepaid.
 
     Section 2.8  Voluntary Conversion of Loans.  The Borrower
 may on any Business Day, upon prior written notice (signed by an
 Authorized Officer) given to the Agent (a) with respect to any
 Conversion to Reference Rate Loans, not later than 11:00 a.m.,
 Los Angeles time, on the second Business Day before the date of
 the proposed Conversion and (b) with respect to any Conversion to
 LIBOR Loans, not later than 11:00 a.m., Los Angeles time, on the
 third Business Day before the date of the proposed Conversion,
 subject to the provisions of Sections 3.2 and 3.3, Convert all
 the Loans of one Type making up the same Borrowing into Loans of
 the other Type; provided, however, that any Conversion of LIBOR
 Loans into Reference Rate Loans shall be made on, and only on,
 the last day of an Interest Period.  Each such notice of a
 Conversion shall, within the restrictions specified above,
 specify (i) the date of such Conversion, (ii) the Loans to be
 Converted and (iii) if such Conversion is into LIBOR Loans, the
 duration of the Interest Period for such Loans.  Each such notice
 of a Conversion shall be irrevocable and binding on the Borrower. 
 The Agent shall give each Bank prompt notice by telecopier of
 each such notice of a Conversion.
 
 B.  LETTERS OF CREDIT
 
     Section 2.9  Issuance of Letters of Credit.
 
          (a)  The Borrower shall be entitled to request the
 issuance of Letters of Credit by giving the Agent a Letter of
 Credit Request at least one (1) Business Day before the requested
 date of issuance of such Letter of Credit (which shall be a
 Business Day).  Any Letter of Credit Request received by the
 Agent later than 3:00 p.m., Los Angeles time, shall be deemed to
 have been received on the next Business Day.  Each Letter of
 Credit Request shall be made by telecopier (subject to the terms
 and conditions of the Teletransmission Agreement), shall be
 signed by an Authorized Officer, shall be irrevocable and shall
 be effective upon receipt by the Agent.  Provided that a valid
 Letter of Credit Request has been received by the Agent and upon
 fulfillment of the other applicable conditions set forth in
 Article 4, the Agent will issue the requested Letter of Credit
 from its office specified in Section 9.2.  If a Letter of Credit
 Request is received by the Agent after 3:00 p.m., Los Angeles
 time, on the Business Day before the requested date of issuance
 of the related Letter of Credit, then the Agent shall use its
 best efforts, but shall not be obligated, to issue such Letter of
 Credit on the requested date of issuance, upon fulfillment of the
 applicable conditions set forth in Article 4.  No Letter of
 Credit shall have an expiration date later than sixty (60) days
 after the Commitment Termination Date.
 
          (b)  Immediately upon the issuance of each Letter of
 Credit, the Agent shall be deemed to have sold and transferred to
 each Bank, and each Bank shall be deemed to have purchased and
 received from the Agent, in each case irrevocably and without any
 further action by any party, an undivided interest and participa-
 tion in such Letter of Credit, each drawing thereunder and the
 obligations of the Borrower under this Agreement in respect
 thereof in an amount equal to the product of (i) a fraction the
 numerator of which is the amount of the Commitment of such Bank
 and the denominator of which is the aggregate amount of all of
 the Commitments and (ii) the maximum amount available to be drawn
 under such Letter of Credit (assuming compliance with all
 conditions to drawing).  The Agent shall promptly advise each
 Bank of the issuance of each Letter of Credit, the Letter of
 Credit Amount of such Letter of Credit, any change in the face
 amount or expiration date of such Letter of Credit, the
 cancellation or other termination of such Letter of Credit and
 any drawing under such Letter of Credit.
 
     Section 2.10  Drawing and Reimbursement.  The payment by the
 Agent of a draft drawn under any Letter of Credit shall consti-
 tute for all purposes of this Agreement the making by Union Bank
 of a Reference Rate Loan in the amount of such payment (without
 any requirement of compliance with the conditions set forth in
 Article 4 or with the limitations contained in Section 2.1(a),
 but subject to Sections 2.3 and 2.7(b)).  In the event that any
 such Loan by Union Bank resulting from a drawing under any Letter
 of Credit is not repaid by the Borrower by 11:00 a.m., Los
 Angeles time, on the day of such drawing, Union Bank shall
 promptly notify the Agent, and the Agent shall promptly notify
 each other Bank.  Each such Bank shall, on the day of such
 notification, make a Reference Rate Loan, which shall be used to
 repay the applicable portion of Union Bank's Reference Rate Loan
 with respect to such Letter of Credit drawing, in an amount equal
 to the amount of such Bank's participation in such drawing for
 application to repay Union Bank (without any requirement of
 compliance with the conditions set forth in Article 4 or with the
 limitations contained in Section 2.1(a), but subject to Sections
 2.3 and 2.7(b)) and shall deliver to the Agent for Union Bank's
 account, on the day of such notification and in immediately
 available funds, the amount of such Reference Rate Loan.  In the
 event that any Bank fails to make available to the Agent for the
 account of Union Bank the amount of such Reference Rate Loan,
 Union Bank shall be entitled to recover such amount on demand
 from such Bank together with interest thereon at the Federal
 Funds Rate.
 
     Section 2.11  Obligations Absolute.  The obligations of the
 Borrower under this Agreement, any Letter of Credit, any Letter
 of Credit Request and any other agreement or instrument relating
 to any Letter of Credit shall be absolute, unconditional and
 irrevocable and shall be paid strictly in accordance with the
 terms of the aforementioned documents under all circumstances,
 including the following:
 
          (a)  any lack of validity or enforceability of any
 Letter of Credit, this Agreement or any other Credit Document;
 
          (b)  the existence of any claim, setoff, defense or
 other right that the Borrower may have at any time against any
 beneficiary or transferee of any Letter of Credit (or any Person
 for whom any such beneficiary or transferee may be acting), the
 Agent, any Bank (other than the defense of payment in accordance
 with the terms of this Agreement) or any other Person, whether in
 connection with this Agreement, any other Credit Document, the
 transactions contemplated hereby or thereby or any unrelated
 transaction;
 
          (c)  any statement or other document presented under
 any Letter of Credit proving to be forged, fraudulent, invalid or
 insufficient in any respect, or any statement therein being
 untrue or inaccurate in any respect whatsoever;
 
          (d)  payment by the Agent under any Letter of Credit
 against presentation of a draft or certificate that does not
 comply with the terms of such Letter of Credit;
 
          (e)  any exchange, release or nonperfection of any
 Collateral or other collateral, or any release, amendment or
 waiver of or consent to departure from any Guaranty, other Credit
 Document or other guaranty, for any of the Obligations of the
 Borrower in respect of the Letters of Credit; and 
 
          (f)  any other circumstance or happening whatsoever,
 whether or not similar to any of the foregoing.
 
     Section 2.12  Letter of Credit Fees and Charges.
 
          (a)  The Borrower shall pay to the Agent for the
 account of the Banks, from June 30, 1997 to the Commitment
 Termination Date, a letter of credit fee at the rate of 1.25% per
 annum on the aggregate of the average daily Letter of Credit
 Amounts of all Letters of Credit outstanding from time to time. 
 Such letter of credit fee shall be payable monthly in arrears on
 the first Business Day of each calendar month, commencing on July
 1, 1997, to the extent accrued during the immediately preceding
 calendar month.
 
          (b)  The Borrower shall pay to the Agent for its own
 account such additional fees and charges (including cable
 charges) as are generally associated with letters of credit, in
 accordance with the Agent's standard internal charge guidelines.
 
     Section 2.13  Limits of Liability of Agent and Banks.
 
          (a)  The Borrower agrees to the provisions in the
 Letter of Credit Request form; provided, however, that the terms
 of this Agreement shall take precedence if there is any inconsis-
 tency between the terms of this Agreement and the terms of said
 form.
 
          (b)  The Borrower assumes all risks of the acts or
 omissions of any beneficiary or transferee of any Letter of
 Credit with respect to its use of such Letter of Credit.  Neither
 the Agent nor any Bank nor any of their respective officers or
 directors shall be liable or responsible for (i) the use that may
 be made of any Letter of Credit or any acts or omissions of any
 beneficiary or transferee in connection therewith; (ii) the
 validity, sufficiency or genuineness of documents, or of any
 endorsement thereof, even if such documents should prove to be in
 any or all respects invalid, insufficient, fraudulent or forged;
 (iii) payment by the Agent against presentation of documents that
 do not comply with the terms of any Letter of Credit, including
 failure of any documents to bear any reference or adequate
 reference to any Letter of Credit; or (iv) any other circumstance
 whatsoever in making or failing to make payment under any Letter
 of Credit; provided, however, that the Borrower shall have a
 claim against the Agent, and the Agent shall be liable to the
 Borrower, to the extent of any direct, but not consequential,
 damages suffered by the Borrower that the Borrower proves were
 caused by (A) the Agent's willful misconduct or gross negligence
 in determining whether documents presented under any Letter of
 Credit comply with the terms of such Letter of Credit or (B) the
 Agent's willful failure to make lawful payment under any Letter
 of Credit after the presentation to the Agent by the beneficiary
 or transferee of such Letter of Credit of a draft and certifi-
 cates strictly complying with the terms and conditions of such
 Letter of Credit.  In furtherance and not in limitation of the
 foregoing, the Agent may accept any document that appears on its
 face to be in order, without responsibility for further investi-
 gation, regardless of any notice or information to the contrary.
 
 C.  PAYMENT PROVISIONS
 
     Section 2.14  Payments.
 
          (a)  The Borrower shall make each payment hereunder and
 under the Notes not later than 11:00 a.m., Los Angeles time, on
 the day when due in U.S. dollars to the Agent at its address set
 forth in Section 9.2, in immediately available funds.  The Agent
 will promptly thereafter cause to be distributed like funds
 relating to the payment of principal, interest or fees ratably
 (other than amounts payable pursuant to Section 2.2(b) or
 Article 3) to the Banks and like funds relating to the payment of
 any other amount payable to any Bank to such Bank, in each case
 to be applied in accordance with the terms of this Agreement.
 
          (b)  The Borrower hereby authorizes each Bank, if and
 to the extent that any payment owed to such Bank is not made when
 due hereunder or under any other Credit Document, to charge from
 time to time against any or all of the Borrower's accounts with
 such Bank any amount so due.
 
          (c)  Unless the Agent receives notice from the Borrower
 before 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 any Bank on such
 due date an amount equal to the amount then due to such Bank.  If
 and to the extent that the Borrower has not so made such payment
 in full to the Agent, each Bank shall repay to the Agent
 forthwith on demand such amount distributed to such Bank,
 together with interest thereon, for each day from the date such
 amount is distributed to such Bank until the date on which such
 Bank repays such amount to the Agent, at the Federal Funds Rate.
 
     Section 2.15  Computation of Interest and Fees.  All
 computations of interest and fees hereunder shall be made on the
 basis of a year of three hundred sixty (360) days for the actual
 number of days (including the first day but excluding the last
 day) occurring in the period for which such interest or fees are
 payable.  Each determination by the Agent of an interest rate
 hereunder shall be conclusive and binding for all purposes,
 absent manifest error.
 
     Section 2.16  Payments on Non-Business Days.  Whenever any
 payment hereunder or under any other Credit Document is stated to
 be due on a day other than a Business Day, such payment shall be
 made on the next succeeding Business Day, and such extension of
 time shall in such case be included in the computation of payment
 of interest or fee, as the case may be; provided, however, that,
 if such extension would cause payment of interest on or principal
 of LIBOR Loans to be made in the next succeeding calendar month,
 such payment shall be made on the next preceding Business Day.
 
     Section 2.17  Sharing of Payments, Etc.  If any Bank obtains
 any payment (whether voluntary, involuntary, through the exercise
 of any right of setoff, or otherwise) on account of the Loans
 made by it or the Letters of Credit participated in by it (other
 than pursuant to Section 2.2(b) or Article 3) in excess of its
 ratable share of payments on account of the Loans and Letters of
 Credit obtained by all of the Banks, then such Bank shall
 forthwith purchase from the other Banks such participations in
 the Loans made by them and the Letters of Credit participated in
 by them as necessary to cause such purchasing Bank to share the
 excess payment ratably with each of them; provided, however,
 that, if all or any portion of such excess payment is thereafter
 recovered from such purchasing Bank, such purchase from any Bank
 shall be rescinded, and such Bank shall repay to the purchasing
 Bank the purchase price to the extent of such recovery together
 with an amount equal to such Bank's ratable share (according to
 the proportion of (a) the amount of such Bank's required
 repayment to (b) the total amount so recovered from the purchas-
 ing Bank) of any interest or other amount paid or payable by the
 purchasing Bank in respect of the total amount so recovered.  The
 Borrower agrees that any Bank so purchasing a participation from
 another Bank pursuant to this section may, to the fullest extent
 permitted by law, exercise all of its rights of payment (includ-
 ing the right of setoff) with respect to such participation as
 fully as if such Bank were the direct creditor of the Borrower in
 the amount of such participation.
 
     Section 2.18  Evidence of Debt.
 
          (a)  The indebtedness of the Borrower resulting from
 all Loans made by each Bank from time to time shall be evidenced
 by the Notes.
 
          (b)  The books and accounts of the Agent shall be
 conclusive evidence, absent manifest error, of all Letter of
 Credit Amounts and of the amounts of all Loans, drawings under
 Letters of Credit, reimbursements under Letters of Credit, fees,
 interest and other charges advanced, due, outstanding or paid
 pursuant to this Agreement or any other Credit Document.
 
 
                           ARTICLE 3.
                        YIELD PROTECTION
 
     Section 3.1  Increased LIBOR Loan Costs.  If, due to either
 (a) the introduction of or any change (other than any change by
 way of imposition or increase of reserve requirements, in the
 case of LIBOR Loans, included in the LIBOR Reserve Percentage) in
 or in the interpretation of any Governmental Rule or (b) compli-
 ance with any Governmental Rule (whether or not having the force
 of law), there is an increase in the cost to any Bank of agreeing
 to make, making, funding or maintaining any LIBOR Loans, then the
 Borrower shall from time to time, upon demand by such Bank (with
 a copy of such demand to the Agent), pay to the Agent for the
 account of such Bank additional amounts sufficient to compensate
 such Bank for such increased cost.  A certificate as to the
 amount of such increased cost, submitted to the Borrower and the
 Agent by such Bank, shall be conclusive and binding for all
 purposes, absent manifest error.
 
     Section 3.2  Illegality.  Notwithstanding any other
 provision of this Agreement, if the introduction of or any change
 in or in the interpretation of any Governmental Rule makes it
 unlawful, or any Governmental Person asserts that it is unlawful,
 for any Bank to perform its obligations hereunder to make LIBOR
 Loans or to continue to fund or maintain LIBOR Loans hereunder,
 then, on notice thereof and demand therefor by such Bank to the
 Borrower through the Agent, (a) the obligation of such Bank to
 make LIBOR Loans and to Convert Loans into LIBOR Loans shall be
 suspended until the Agent notifies the Borrower that such Bank
 has determined that the circumstances causing such suspension no
 longer exist, and (b) the Borrower shall forthwith prepay in full
 all LIBOR Loans of such Bank then outstanding, together with
 interest accrued thereon, unless the Borrower, within five
 (5) Business Days of such notice and demand, Converts all LIBOR
 Loans of all Banks then outstanding into Reference Rate Loans in
 accordance with Section 2.8.
 
     Section 3.3  Inadequacy of LIBOR.  If, with respect to any
 LIBOR Loan, the Majority Banks notify the Agent that the interest
 rate determined pursuant to Section 2.6(a)(ii) for any Interest
 Period for such Loan will not adequately reflect the cost to the
 Majority Banks of making, funding or maintaining their respective
 LIBOR Loans for such Interest Period, then the Agent shall
 forthwith so notify the Borrower and the Banks, whereupon (a) all
 LIBOR Loans will automatically, on the last day of the then
 existing respective Interest Periods therefor, Convert into
 Reference Rate Loans, and (b) the obligations of the Banks to
 make, or to Convert Loans into, LIBOR Loans shall be suspended
 until the Agent notifies the Borrower and the Banks that the
 circumstances causing such suspension no longer exist.
 
     Section 3.4  Increased Letter of Credit Costs.  If, after
 the date hereof, any change in any Governmental Rule or in the
 interpretation thereof by any Governmental Person charged with
 the administration thereof either (a) imposes, modifies or deems
 applicable any reserve, special-deposit or similar requirement
 against letters of credit or guaranties issued by or participated
 in, or assets held by, or deposits in or for the account of, the
 Agent or any Bank or (b) imposes on the Agent or any Bank any
 other condition regarding this Agreement, the Agent, such Bank or
 any Letter of Credit, and the result of any event referred to in
 the preceding clause (a) or (b) is to increase the cost to the
 Agent of issuing or maintaining any Letter of Credit or to any
 Bank of purchasing or maintaining any participation therein,
 then, upon demand by the Agent or by such Bank through the Agent,
 the Borrower shall pay to the Agent or to such Bank through the
 Agent, from time to time as specified by the Agent or by such
 Bank through the Agent, additional amounts sufficient to
 compensate the Agent or such Bank for such increased cost.  A
 certificate as to the amount of such increased cost, submitted to
 the Borrower by the Agent or such Bank, shall be conclusive and
 binding for all purposes, absent manifest error.
 
     Section 3.5  Capital Adequacy.  If any Bank determines that
 compliance with any Governmental Rule (whether or not having the
 force of law) affects or would affect the amount of capital
 required or expected to be maintained by such Bank or any
 corporation controlling such Bank and that the amount of such
 capital is increased by or based upon the existence of such
 Bank's commitment to lend hereunder and other commitments of this
 type or the commitment to issue or participate in, or the
 issuance of or participation in, the Letters of Credit (or
 similar contingent obligations), then, upon demand by such Bank
 (with a copy of such demand to the Agent), the Borrower shall pay
 to the Agent for the account of such Bank, from time to time as
 specified by such Bank, additional amounts sufficient to
 compensate such Bank in the light of such circumstances, to the
 extent that such Bank reasonably determines such increase in
 capital to be allocable to the existence of such Bank's commit-
 ment to lend hereunder or commitment to issue or participate in,
 or the issuance of or participation in, Letters of Credit.  A
 certificate as to such amounts submitted to the Borrower by such
 Bank shall be conclusive and binding for all purposes, absent
 manifest error.
 
     Section 3.6  Funding Losses.  If any payment of principal
 of, or Conversion of, any LIBOR Loan is made other than on the
 last day of an Interest Period relating to such Loan, as a result
 of a payment or Conversion pursuant to Section 3.2 or accelera-
 tion of the maturity of the Obligations pursuant to Section 7.1
 or for any other reason, the Borrower shall, upon demand by any
 Bank (with a copy of such demand to the Agent), pay to the Agent
 for the account of such Bank any amounts required to compensate
 such Bank for any additional losses, costs or expenses that it
 may reasonably incur as a result of such payment or Conversion,
 including any loss (including loss of anticipated profits), cost
 or expense incurred by reason of the liquidation or reemployment
 of deposits or other funds acquired by such Bank to fund or
 maintain such Loan.
 
     Section 3.7  Substitution of Bank.  If (a) any Bank demands
 payment from the Borrower in any material amount pursuant to
 Section 3.1, 3.4 or 3.5 or (b) any Bank gives notice of illegali-
 ty pursuant to Section 3.2, and in either case the event or
 circumstances causing such Bank to make such demand or give such
 notice is not applicable to the Majority Banks, then the Borrower
 shall have the right, with the assistance of the Agent, to seek
 a mutually satisfactory bank or banks (which may be one or more
 of the Banks) to substitute for such Bank by purchasing the
 Obligations and assuming the Commitment of such Bank; provided,
 however, that in any event the Borrower shall be obligated to
 compensate such Bank pursuant to Section 3.1, 3.4 or 3.5 or to
 prepay such Bank's LIBOR Loans pursuant to Section 3.2, as
 applicable.

 of their respective officers) in or in connection with any Credit
 Document proves to have been incorrect in any material respect
 when made;
 
          (c)  the Borrower or FOC, as applicable, fails to
 perform or observe any term, covenant or agreement contained in
 Article 6.B. or in Section 7.2 of the FOC Guaranty; or the
 Borrower or any Affiliate fails to perform or observe any other
 term, covenant or agreement of any Credit Document on its part to
 be performed or observed, and the same is not remedied within ten
 (10) days after written notice thereof has been given to the
 Borrower by the Agent;
 
          (d)  the Borrower, any Affiliate or any Subsidiary of
 any thereof fails to pay any principal of any Debt thereof
 outstanding in a principal amount of at least one million dollars
 ($1,000,000) in the aggregate (excluding the Obligations), or any
 interest or premium thereon, when due (whether by scheduled
 maturity, required prepayment, acceleration, demand or other-
 wise), and such failure continues after the applicable grace
 period, if any, specified in the agreement or instrument relating
 to such Debt; any other event occurs or condition exists under
 any agreement or instrument relating to any such Debt and
 continues after the applicable grace period, if any, specified in
 such agreement or instrument, if the effect of such event or
 condition is to accelerate, or to permit the acceleration of, the
 maturity of such Debt; or any such Debt is declared to be due and
 payable, or is required to be prepaid, redeemed, purchased or
 defeased (other than by a regularly scheduled required prepay-
 ment, redemption, purchase or defeasance), or an offer to prepay,
 redeem, purchase or defease such Debt is required to be made, in
 each case before the stated maturity thereof;
 
          (e)  the Borrower, any Affiliate or any Subsidiary of
 any thereof generally does not pay its debts as such debts become
 due, admits in writing its inability to pay its debts generally
 or makes a general assignment for the benefit of creditors; any
 proceeding is instituted by or against the Borrower, any
 Affiliate or any Subsidiary of any thereof seeking to adjudicate
 it a bankrupt or insolvent, seeking liquidation, winding up,
 reorganization, arrangement, adjustment, protection, relief, or
 composition of it or its debts under any law relating to
 bankruptcy, insolvency or reorganization or relief of debtors, or
 seeking the entry of an order for relief or the appointment of a
 receiver, trustee or other similar official for it or for any
 substantial part of its property; or the Borrower, any Affiliate
 or any Subsidiary of any thereof takes any corporate action to
 authorize any of the actions set forth above in this subsec-
 tion (e);
 
          (f)  any judgment or order for the payment of money in
 excess of one million dollars ($1,000,000) is rendered against
 the Borrower, any Affiliate or any Subsidiary of any thereof, and
 either (i) enforcement proceedings are commenced by any creditor
 upon such judgment or order or (ii) there is any period of ten
 (10) consecutive days (or, if the entire amount is covered by
 insurance (subject to applicable deductibles), 30 consecutive
 days) during which a stay of enforcement of such judgment or
 order, by reason of a pending appeal or otherwise, is not in
 effect, unless such judgment or order has been vacated, satis-
 fied, dismissed, or bonded pending appeal or, in the case of a
 judgment or order the entire amount of which is covered by
 insurance (subject to applicable deductibles), is the subject of
 a binding agreement with the plaintiff and the insurer covering
 payment therefor;
 
          (g)  there occurs, in the reasonable judgment of the
 Majority Banks, any material adverse change in the business,
 condition (financial or otherwise), operations, performance,
 properties or prospects of the Borrower, FHI, FOC, FRI, FPLI or
 any Subsidiary of any thereof;
 
          (h)  any provision of any Credit Document for any
 reason ceases to be valid and binding on or enforceable against,
 in any material respect, the Borrower or any Affiliate party
 thereto, or the Borrower or such Affiliate so states in writing;
 or
 
          (i)  for any reason except to the extent permitted by
 the terms of the Security Agreement, the Account Pledge Agree-
 ment, the Note Pledge Agreement or the Stock Pledge Agreement,
 there ceases to be a valid and perfected first-priority security
 interest in favor of the Agent in any of the Collateral purported
 to be covered by any of such agreements; 
 
 then, and in any such event, the Agent (i) shall at the request,
 or may with the consent, of the Majority Banks, by notice to the
 Borrower, declare the obligation of each Bank to make Loans, and
 the obligation of the Agent to issue Letters of Credit, to be
 terminated, whereupon the same shall forthwith terminate, and
 (ii) shall at the request, or may with the consent, of the
 Majority Banks, by notice to the Borrower, declare the Obliga-
 tions, all interest thereon and all other amounts payable under
 this Agreement and the other Credit Documents to be forthwith due
 and payable, whereupon (A) the Obligations, all such interest and
 all such amounts shall become and be forthwith due and payable,
 without presentment, demand, protest or further notice of any
 kind, all of which are hereby expressly waived by the Borrower,
 and (B) to the extent any Letters of Credit are then outstanding,
 the Borrower shall deposit with and pledge to the Agent cash
 collateral in the aggregate Letter of Credit Amount of such
 Letters of Credit; provided, however, that, in the event of an
 actual or deemed entry of an order for relief with respect to the
 Borrower, any Affiliate or any Subsidiary of any thereof under
 the Federal Bankruptcy Code, (x) the obligation of each Bank to
 make Loans and of the Agent to issue Letters of Credit shall be
 terminated automatically, and (y) the Loans, all such interest
 and all such amounts (including such cash collateral) shall
 automatically become and be due and payable, without presentment,
 demand, protest or any notice of any kind, all of which are
 hereby expressly waived by the Borrower.
 
 
                           ARTICLE 8.
                           THE AGENT
 
     Section 8.1  Authorization and Action.  Each Bank hereby
 appoints and authorizes the Agent to take such action as agent on
 its behalf and to exercise such powers under this Agreement as
 are delegated to the Agent by the terms hereof, together with
 such powers as are reasonably incidental thereto.  As to any
 matters not expressly provided for by the Credit Documents
 (including enforcement of and collection under the Credit
 Documents), the Agent shall not be required to exercise any
 discretion or take any action, but shall be required to act or to
 refrain from acting (and shall be fully protected in so acting or
 refraining from acting) upon the instructions of the Majority
 Banks, and such instructions shall be binding upon all Banks and
 all holders of Notes; provided, however, that the Agent shall not
 be required to take any action that exposes the Agent to personal
 liability or that is contrary to the Credit Documents or
 applicable law.  The Agent agrees to give each Bank prompt notice
 of each notice given to it by the Borrower pursuant to the terms
 of this Agreement.
 
     Section 8.2  Agent's Reliance, Etc.  Neither the Agent nor
 any of its directors, officers, agents or employees shall be
 liable for any action taken or omitted to be taken by it or them
 under or in connection with the Credit Documents, except for its
 or their own gross negligence or willful misconduct.  Without
 limitation of the generality of the foregoing, the Agent (a) may
 treat any Bank that has signed this Agreement or an Assignment
 and Acceptance as the holder of the applicable portion of the
 Obligations; (b) may consult with legal counsel (including
 counsel for the Borrower or any Affiliate), independent public
 accountants and other experts selected by it and shall not be
 liable for any action taken or omitted to be taken in good faith
 by it in accordance with the advice of such counsel, accountants
 or experts; (c) makes no warranty or representation to any Bank
 and shall not be responsible to any Bank for any statements,
 warranties or representations made in or in connection with the
 Credit Documents; (d) shall not have any duty to ascertain or to
 inquire as to the performance or observance of any of the terms,
 covenants or conditions of any Credit Document on the part of the
 Borrower or any Affiliate or to inspect the property (including
 the books and records) of the Borrower or any Affiliate;
 (e) shall not be responsible to any Bank for the due execution,
 legality, validity, enforceability, genuineness, sufficiency or
 value of any Credit Document or any other instrument or document
 furnished pursuant hereto or thereto; and (f) shall incur no
 liability under or in respect of any Credit Document by acting
 upon any notice, consent, certificate or other instrument or
 writing (which may be by telecopier or otherwise) believed by it
 to be genuine and signed or sent by the proper party or parties.
 
     Section 8.3  Union Bank and Affiliates.   With respect to
 its Commitment, the Loans made by it, the Note issued to it and
 the Letters of Credit participated in by it, Union Bank shall
 have the same rights and powers under this Agreement as any other
 Bank and may exercise the same as though it were not the Agent;
 and the term "Bank" or "Banks" shall, unless otherwise expressly
 indicated, include Union Bank in its individual capacity.  Union
 Bank and its affiliates may accept deposits from, lend money to,
 act as trustee under indentures of, and generally engage in any
 kind of business with, the Borrower, any Affiliate, any Subsid-
 iary of any thereof and any Person that may do business with or
 own securities of the Borrower, any Affiliate or any such
 Subsidiary, all as if Union Bank were not the Agent and without
 any duty to account therefor to the Banks.
 
     Section 8.4  Bank Credit Decision.  Each Bank acknowledges
 that it has, independently and without reliance on the Agent or
 any other Bank and based on the financial statements referred to
 in Section 6(e) of the FOC Guaranty and such other 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 on the Agent or any other Bank and based on such
 documents and information as it deems appropriate at the time,
 continue to make its own credit decisions in taking or not taking
 action under this Agreement.
 
     Section 8.5  Indemnification.  The Banks agree to indemnify
 the Agent (to the extent not promptly reimbursed by the Borrow-
 er), ratably according to the respective principal amounts of the
 Obligations then held by each of them (or if no Obligations are
 at the time outstanding or if any Obligations are then held by
 Persons that are not Banks, ratably according to the respective
 amounts of their Commitments), from and against any and all
 liabilities, obligations, losses, damages, penalties, actions,
 judgments, suits, costs, expenses and disbursements of any kind
 or nature whatsoever that may be imposed on, incurred by or
 asserted against the Agent in any way relating to or arising out
 of the Credit Documents or any action taken or omitted by the
 Agent under the Credit Documents; provided, however, that no Bank
 shall be liable for any portion of such liabilities, obligations,
 losses, damages, penalties, actions, judgments, suits, costs,
 expenses or disbursements resulting from the Agent's gross
 negligence or willful misconduct.  Without limitation of the
 foregoing, each Bank agrees to reimburse the Agent promptly upon
 demand for its ratable share of any costs and expenses payable by
 the Borrower under Section 9.4, to the extent that the Agent is
 not reimbursed for such costs and expenses by the Borrower.
 
     Section 8.6  Successor Agent.  The Agent may resign at any
 time by giving written notice thereof to the Banks and the
 Borrower and may be removed at any time with or without cause
 with the written approval of the Majority Banks.  Upon any such
 resignation or removal, the Majority Banks shall have the right
 to appoint a successor Agent.  If no successor Agent has been so
 appointed by the Majority Banks, and has accepted such appoint-
 ment, within thirty (30) days after the retiring Agent's giving
 of notice of resignation or the Majority Banks' removal of the
 retiring Agent, then the retiring Agent may, on behalf of the
 Banks, appoint a successor Agent, which shall be a commercial
 bank organized under the laws of the United States of America or
 of any state thereof and having a combined capital and surplus of
 at least five hundred million dollars ($500,000,000).  Upon the
 acceptance of any appointment as Agent hereunder by a successor
 Agent, such successor Agent shall thereupon succeed to and become
 vested with all of the rights, powers, privileges and duties of
 the retiring Agent, and the retiring Agent shall be discharged
 from its duties and obligations under the Credit Documents. 
 After any retiring Agent's resignation or removal hereunder as
 Agent, the provisions of this Article 8 shall inure to its
 benefit as to any actions taken or omitted to be taken by it
 while it was agent under this Agreement.
 
     Section 8.7  Agent as Collateral Holder.
 
          (a)  Except for action expressly required of the Agent
 hereunder or under any other Credit Document as holder of any
 Collateral, the Agent shall in all cases be fully justified in
 refusing to act hereunder and thereunder unless it is further
 indemnified to its satisfaction by the Banks, proportionately in
 accordance with the Obligations then due and payable to each of
 them, against any and all liability and expense that may be
 incurred by the Agent by reason of taking or continuing to take
 any such action.
 
          (b)  Except as expressly provided herein, the Agent
 shall have no duty to take any affirmative steps with respect to
 the collection of amounts payable in respect of the Collateral. 
 The Agent shall incur no liability as a result of any private
 sale of the Collateral.
 
          (c)  The Banks hereby consent, and agree upon written
 request by the Agent to execute and deliver such instruments and
 other documents as the Agent may deem desirable to confirm such
 consent, to the release of the Liens on the Collateral, including
 any release in connection with any sale, transfer or other
 disposition of the Collateral or any part thereof, in accordance
 with the Credit Documents.
 
          (d)  The Agent shall be deemed to have exercised
 reasonable care in the custody and preservation of the Collateral
 in its possession if the Collateral is accorded treatment
 substantially equal to that the Agent accords its own property,
 it being understood that neither the Agent nor any Bank shall
 have responsibility for (i) ascertaining or taking action with
 respect to calls, conversions, exchanges, maturities, tenders or
 other matters relative to any Collateral, whether or not the
 Agent or any Bank is deemed to have knowledge of such matters, or
 (ii) taking any necessary steps to preserve rights against any
 parties with respect to any Collateral.
 
 
                           ARTICLE 9.
                         MISCELLANEOUS
 
     Section 9.1  Amendments, Etc.  No amendment or waiver of any
 provision of this Agreement or any Note, or consent to any
 departure by the Borrower therefrom, shall be effective unless in

 Banks (and, in the case of amendments, the Borrower), and then
 such waiver or consent shall be effective only in the specific

     Section 9.3  No Waiver; Remedies.  No failure on the part of
 any Bank or the Agent to exercise, and no delay in exercising,
 any right hereunder shall operate as a waiver thereof, and no
 single or partial exercise of any such right shall preclude any
 other or further exercise thereof or the exercise of any other
 right.  The remedies provided herein are cumulative and not
 exclusive of any remedies provided by law.
 
     Section 9.4  Costs and Expenses.  The Borrower agrees to pay
 on demand (a) all costs and expenses of the Agent in connection
 with the preparation, execution, delivery, administration,
 modification and amendment of this Agreement, the other Credit
 Documents and the other documents to be delivered hereunder,
 including (i) the reasonable fees and out-of-pocket expenses of

 bankruptcy, insolvency or similar proceeding or otherwise.
 
     Section 9.5  Indemnification.  The Borrower hereby agrees to
 indemnify and hold harmless the Agent and each Bank and each of
 their respective officers, directors, employees, agents, advisors
 and affiliates (each an "Indemnified Person") from and against
 any and all claims, damages, losses, liabilities, costs and
 expenses (including reasonable attorneys' fees and expenses,
 whether or not such Indemnified Person is named as a party to any
 proceeding or is otherwise subjected to judicial or legal process
 arising from any such proceeding) that any of them may incur, or
 that may be claimed, asserted or awarded against any of them by
 any Person, in each case arising out of, related to or in

 any Loan, any Letter of Credit, the Wainoco Note Offering, the
 consummation of any transaction contemplated hereby or thereby,
 the transfer of or payment or failure to pay under any Letter of
 Credit or the use by the Borrower or the beneficiary of any

 final, nonappealable judgment by a court of competent jurisdic-
 tion to have resulted from such Indemnified Person's gross
 negligence or willful misconduct.
 
     Section 9.6  Right of Setoff.  Upon (a) the occurrence and
 during the continuation of any Event of Default and (b) the
 making of the request or the granting of the consent specified by
 Section 7.1 to authorize the Agent to declare the Obligations due

 is hereby authorized at any time and from time to time, to the
 fullest extent permitted by law, to set off and apply any and all
 deposits (general or special, time or demand, provisional or
 final) at any time held and other indebtedness at any time owing
 by such Bank to or for the credit or the account of the Borrower
 against any and all of the obligations of the Borrower now or
 hereafter existing under this Agreement and the other Credit
 Documents, irrespective of whether such Bank has made any demand
 under this Agreement or any such other Credit Document and
 although such obligations may be unmatured.  Each Bank agrees to
 notify the Borrower promptly after any such setoff and applica-
 tion made by such Bank; provided, however, that the failure to
 give such notice shall not affect the validity of such setoff and
 application.  The rights of each Bank under this section are in

 (ii) to any bank or other entity as necessary, or as reasonably
 deemed by such assigning Bank to be appropriate, in order to

 affiliate of such Bank, all of or a portion of its rights and
 obligations under this Agreement (including all or a portion of

 outstanding Letters of Credit); provided, however, that (A)
 except in the case of an assignment to a Person that, immediately
 before such assignment, was a Bank, the amount of the Commitment
 of the assigning Bank being assigned pursuant to each such
 assignment (determined as of the date of the Assignment and
 Acceptance with respect to such assignment) shall in no event be
 less than five million dollars ($5,000,000) and (B) the parties
 to each such assignment shall execute and deliver to the Agent,
 for its acceptance and recording in the Register, an Assignment
 and Acceptance.  Upon such execution, delivery, acceptance and
 recording, from and after the effective date specified in each
 Assignment and Acceptance, which effective date shall be at least
 five (5) Business Days after the date of delivery thereof to the
 Agent or, if so specified in such Assignment and Acceptance, the
 date of acceptance thereof by the Agent, (1) the assignee
 thereunder shall be a party hereto and, to the extent that rights
 and obligations hereunder have been assigned to it pursuant to
 such Assignment and Acceptance, shall have the rights and
 obligations of a Bank hereunder and (2) the Bank assignor
 thereunder shall, to the extent that rights and obligations
 hereunder have been assigned by it pursuant to such Assignment
 and Acceptance, relinquish its rights and be released from its
 obligations under this Agreement.
 
          (b)  By executing and delivering an Assignment and
 Acceptance, the Bank assignor thereunder and the assignee
 thereunder confirm to and agree with each other and the other
 parties hereto as follows:  (i) other than as provided in such
 Assignment and Acceptance, such assigning Bank makes no represen-
 tation or warranty and assumes no responsibility with respect to

 connection with this Agreement or the execution, legality,
 validity, enforceability, genuineness, sufficiency or value of
 this Agreement or any other instrument or document furnished
 pursuant hereto; (ii) such assigning Bank makes no representation
 or warranty and assumes no responsibility with respect to the
 financial condition of the Borrower, any Affiliate or any of
 their respective Subsidiaries or the performance or observance by
 the Borrower or any Affiliate of any of their respective
 obligations under this Agreement or any other instrument or
 document furnished pursuant hereto; (iii) such assignee confirms
 that it has received a copy of this Agreement, together with
 copies of the financial statements referred to in Section 6(e) of
 the FOC Guaranty and such other documents and information as it
 has deemed appropriate to make its own credit analysis and
 decision to enter into such Assignment and Acceptance; (iv) such
 assignee will, independently and without reliance upon the Agent,
 such assigning Bank or any other Bank and based on such documents
 and information as it may deem appropriate at the time, continue
 to make its own credit decisions in taking or not taking action
 under this Agreement; (v) such assignee appoints and authorizes
 the Agent to take such action as agent on its behalf and to
 exercise such powers under this Agreement as are delegated to the
 Agent by the terms hereof, together with such powers as are
 reasonably incidental thereto; and (vi) such assignee agrees that
 it will perform in accordance with their terms all of the
 obligations that by the terms of this Agreement are required to
 be performed by it as a Bank.
 
          (c)  The Agent shall maintain at its address set forth
 in Section 9.2 a copy of each Assignment and Acceptance delivered
 to and accepted by it and a register for the recordation of the
 names and addresses of the Banks and the Commitment of, and the
 amount of Obligations owing to, each Bank from time to time (the
 "Register").  The entries in the Register shall be conclusive and
 binding for all purposes, absent manifest error, and the
 Borrower, the Agent and the Banks may treat each Person whose
 name is recorded in the Register as a Bank hereunder for all
 purposes of this Agreement.  The Register shall be available for
 inspection by the Borrower or any Bank at any reasonable time and
 from time to time upon reasonable prior notice.
 
          (d)  Upon its receipt of an Assignment and Acceptance
 executed by an assigning Bank and an assignee, the Agent shall,
 if such Assignment and Acceptance has been completed and is in
 proper form and if such assignee is acceptable to the Agent,
 (i) accept such Assignment and Acceptance, (ii) record the
 information contained therein in the Register and (iii) give
 prompt notice thereof to the Borrower.
 
          (e)  Each Bank may sell participations to one or more
 banks or other entities in or to all or a portion of its rights
 and obligations under this Agreement (including all or a portion
 of its Commitments, the Loans owing to it and its participations
 in outstanding Letters of Credit); provided, however, that
 (i) such Bank's obligations under this Agreement (including its
 Commitment to the Borrower hereunder) shall remain unchanged,
 (ii) such Bank shall remain solely responsible to the other
 parties hereto for the performance of such obligations, (iii) the
 Borrower, the Agent and the other Banks shall continue to deal
 solely and directly with such Bank in connection with such Bank's
 rights and obligations under this Agreement and (iv) no partici-
 pant under any such participation shall have any right to approve
 any amendment or waiver of any provision of any Credit Document,
 or any consent to any departure by the Borrower or any Affiliate
 therefrom, except to the extent that such amendment, waiver or
 consent would reduce the principal of, or interest on, the Loans
 or any fees or other amounts payable hereunder, in each case to
 the extent subject to such participation, postpone any date fixed
 for any payment of principal of, or interest on, the Loans or any
 fees or other amounts payable hereunder, in each case to the
 extent subject to such participation, or release all or substan-
 tially all of the Collateral, except as provided in the Credit
 Documents.
 
          (f)  Any Bank may, in connection with any assignment or
 participation or proposed assigned or participation pursuant to
 this Section 9.8, disclose to the assignee or participant or
 proposed assignee or participant any information relating to the
 Borrower furnished to such Bank by or on behalf of the Borrower.

 arbitrator shall be selected pursuant to the Commercial Rules of
 the AAA.  However, the arbitrator selected must be a retired
 state- or federal-court judge with at least 5 years of judicial
 experience in civil matters.  In the event that the selection
 pursuant to the Commercial Rules of the AAA does not result in
 the appointment of a single neutral arbitrator within 30 days,
 any Party may petition the court to appoint a single neutral
 arbitrator who is a retired state- or federal-court judge with at
 least 5 years of judicial experience in civil matters.  The
 Parties shall bear equally the fees and expenses of the arbitra-
 tor unless the arbitrator otherwise provides in any award
 thereby.
 
          (c)  Powers of and Limitations on Arbitrator.  The
 arbitrator shall have the powers provided by the California
 Arbitration Act and the Commercial Rules of the AAA, including
 the powers described below, except as provided in this Section
 9.12.
 
               (i)  The arbitrator shall determine all challenges
 to the legality or enforceability of this Section 9.12.
 
              (ii)  The arbitrator shall apply the rules of
 evidence to the same extent as they would be applied in a court
 of law.
 
             (iii)  The arbitrator shall give effect to all legal
 and equitable defenses in determining any claim or controversy,
 including statutes of limitation, the statute of frauds, waiver
 and estoppel.
 
              (iv)  A Party may not conduct discovery unless the
 arbitrator grants such Party leave to do so upon a showing of
 good cause.  All discovery shall be completed within 90 days
 after the appointment of the arbitrator.  The arbitrator shall
 limit discovery to nonprivileged material that is relevant to the
 issues to be determined by the arbitrator.
 
               (v)  The AAA shall determine the time of the
 hearing and shall designate its location from among the cities of
 Los Angeles, San Diego and San Francisco, based upon the conve-
 nience of the arbitrator, the Parties and any witnesses.  How-
 ever, such hearing shall be commenced within 30 days after
 completion of discovery, unless the arbitrator grants a continu-
 ance upon a showing of good cause by any Party.  At least 7 days
 before the date set for such hearing, the Parties shall exchange
 copies of exhibits to be offered as evidence, and lists of the
 witnesses who will testify, at such hearing.  Once commenced, the
 hearing shall proceed from day to day until completed, unless the
 arbitrator grants a continuance upon a showing of good cause by
 any Party.  Any Party may cause to be prepared, at its expense,
 a written transcription or electronic recordation of such
 hearing.
 
              (vi)  Any award by the arbitrator shall be set
 forth in a written decision supported by findings of fact and
 conclusions of law that the arbitrator shall deliver to the
 Parties concurrently with such award.
 
             (vii)  The award of the arbitrator may include
 equitable relief.
 
            (viii)  The arbitrator may not award punitive damages
 unless the arbitrator first makes written findings of fact that
 would satisfy the requirements for recovery of punitive damages
 under California law.  No such award of punitive damages shall
 exceed a sum equal to twice the amount of actual damages as
 determined by the arbitrator.
 
              (ix)  The arbitrator shall have the power to award
 reasonable attorneys' fees (including a reasonable allocation for
 the costs of in-house counsel) and costs to the prevailing party.
 
               (x)  The provisions of California Civil Code
 Sections 47 et seq. shall apply to the arbitration to the same
 extent as they would apply to a judicial proceeding subject to
 such provisions.
 
              (xi)  The laws of the State of California shall
 govern the arbitration pursuant to this Section 9.12.
 
          (d)  Provisional Remedies, Self-Help and Foreclosure. 
 No provision of this Section 9.12 shall limit the right of any
 Party (i) to exercise self-help remedies, including setoff,
 (ii) to foreclose against or sell any collateral, by power of
 sale or otherwise, or (iii) to obtain or oppose provisional or
 ancillary remedies from a court of competent jurisdiction before,
 after or during the pendency of the arbitration.  The exercise
 of, or opposition to, any such remedy shall not waive the right
 of any Party to arbitration pursuant to this Section 9.12.  If
 any obligation under any Credit Document is or becomes secured by
 an interest in real property, then no claim or controversy shall
 be submitted to arbitration without the consent of all Parties. 
 If any Party does not consent to such submission, then the claim
 or controversy shall be determined by a judicial action in which
 all decisions of fact and law shall, at the request of any Party,
 be referred to a referee in accordance with California Code of
 Civil Procedure Sections 638 et seq.  The referee shall be
 selected pursuant to the provisions of Section 9.12(b) and shall
 have the powers conferred upon an arbitrator by Section 9.12(c). 
 Judgment upon the award rendered by such referee shall be entered
 in the court in which such judicial action was commenced, in
 accordance with California Code of Civil Procedure Sections 644
 et seq.
 
          (e)  Miscellaneous.  Judgment upon the award of the
 arbitrator may be entered in any court of competent jurisdiction. 
 In the event that multiple claims are asserted, some of which are
 found to be not subject to this Section 9.12, the Parties agree
 to stay the proceedings of the claims not subject to this Section
 9.12 until all other claims are resolved in accordance with this
 Section 9.12.  In the event that claims are asserted against
 multiple parties, some of which are not subject to this Section
 9.12, the Parties agree to sever the claims subject to this
 Section 9.12 and to resolve them in accordance with this Section
 9.12.  In the event that any provision of this Section 9.12 is
 found to be illegal or unenforceable, the remainder of this
 Section 9.12 shall remain in full force and effect.
 
     Section 9.13  Reference to and Effect on Credit Documents.
 
          (a)  On and after the effective date of this Agreement,
 each reference in the other Credit Documents to "the Credit
 Agreement," "thereunder," "thereof," "therein" or any other
 expression of like import referring to the Revolving Credit and
 Letter of Credit Agreement dated as of August 10, 1992 among the
 parties to this Agreement shall mean and be a reference to this
 Agreement.
 
          (b)  Except as amended or amended and restated as of the date
 hereof, the Credit Documents shall remain in full force and effect and are
 hereby ratified and confirmed.  Without limiting the generality of the
 foregoing, the Security Agreement, the Account Pledge Agreement, the Note
 Pledge Agreement, the Stock Pledge Agreement and all of the Collateral
 described therein do and shall continue to secure the payment of all
 obligations stated to be secured thereby under this Agreement and the
 other Credit Documents.
 
          (c)  The execution, delivery and effectiveness of this
 Agreement shall not operate as a waiver of any right, power or
 remedy of any Bank or the Agent under any of the Credit Documents
 or constitute a waiver of any provision of any of the Credit
 Documents.
