         of Exhibit C hereto, (i) in the case of Eurodollar Loans, not later
         than 9:00 a.m., Houston, Texas time, three Business Days before the
         Borrowing Date specified for a proposed Competitive Borrowing and (ii)
         in the case of Fixed Rate Loans, not later than 8:30 a.m., Houston,
         Texas time, on the day of a proposed Competitive Borrowing.
         Competitive Bids that do not conform substantially to the format of
         Exhibit C may be rejected by the Auction Administration Agent after
         conferring with, and upon the instruction of, the Company, and the
         Auction Administration Agent shall notify the non-conforming Bank of
         such rejection as soon as practicable.  Each Competitive Bid shall
         refer to this Agreement and (x) specify the principal amount (which
         shall be in a minimum principal amount of $5,000,000 and in an
         integral multiple of $1,000,000 and which may equal the entire
         principal amount of the Competitive Borrowing requested by the
         Company) of the Competitive Loan the Bank is willing to make to the
         Company, (y) specify the Competitive Bid Rate(s) at which the Bank is
         prepared to make the Competitive Loan and (z) confirm the Interest
         Period with respect thereto specified by the Company in its
         Competitive Bid Request.  A Competitive Bid submitted by a Bank
         pursuant to this paragraph (b) shall be irrevocable.

                 (c)         The Auction Administration Agent shall promptly
         notify the Company by telecopier of all the Competitive Bids made, the
         Competitive Bid Rate and the principal amount of each Competitive Loan
         in respect of which a Competitive Bid was made and the identity of the
         Bank that made each bid.  The Auction Administration Agent shall send
         a copy of all Competitive Bids to the Company for its records as soon
         as practicable after completion of the bidding process set forth in
         this Section 2.2.

                 (d)         The Company may in its sole and absolute
         discretion, subject only to the provisions of this Section 2.2(d),
         accept or reject any or all of the Competitive Bids referred to in
         paragraph (c) above; provided, however, that the aggregate amount of
         the Competitive Bids so accepted by the Company may not exceed the
         principal amount of the Competitive Borrowing requested by the
         Company.  The Company shall notify the Auction Administration Agent by
         telecopier whether and to what extent it has decided to accept or
         reject any or all of the bids referred to in paragraph (c) above, (i)
         in the case of Eurodollar Loans, not later than 11:00 a.m., Houston,
         Texas time, three Business Days before the Borrowing Date specified
         for a proposed Competitive Borrowing and (ii) in the case of Fixed
         Rate Loans, not later than 9:30 a.m., Houston, Texas time, on the day
         specified for a proposed Competitive Borrowing; provided, however,
         that (w) the failure by the Company to give such notice shall be
         deemed to be a rejection of all the bids referred to in paragraph (c)
         above, (x) the Company shall not accept a bid made at a particular
         Competitive Bid Rate if the Company has decided to reject a bid made
         at a lower Competitive Bid Rate, (y) if the Company shall accept bids
         made at a particular Competitive Bid Rate but shall be restricted by
         other conditions hereof from borrowing the full principal amount of
         Competitive Loans in respect of which bids at such Competitive Bid
         Rate have been made or shall not require the full amount offered
         thereby, then the Company shall accept a pro rata portion of each bid
         made at such Competitive Bid Rate based as nearly as possible on the
         respective principal amounts of Competitive Loans for which such bids
         were made and (z) no bid shall be accepted for a Competitive Loan
         unless such Competitive Loan is in a





                                      -23-
   29
         minimum principal amount of $5,000,000 and an integral multiple of
         $1,000,000.  Notwithstanding the foregoing clause (z), if it is
         necessary for the Company to accept a pro rata allocation of the bids
         made in response to a Competitive Bid Request (whether pursuant to the
         events specified in clause (y) above or otherwise) and the available
         principal amount of Competitive Loans to be allocated among the Banks
         is not sufficient to enable Competitive Loans to be allocated to each
         Bank in a minimum principal amount of $5,000,000 and in integral
         multiples of $1,000,000, then the Company shall select the Banks to be
         allocated such Competitive Loans and shall round allocations up or
         down to the next higher or lower multiple of $500,000 as it shall deem
         appropriate.  A notice given by the Company pursuant to this paragraph
         (d) shall be irrevocable.

                 (e)         The Auction Administration Agent shall promptly
         notify each bidding Bank whether or not its Competitive Bid has been
         accepted (and if so, in what amount and at what Competitive Bid Rate)
         by telecopier, and each successful bidder will thereupon become bound,
         subject to the other applicable conditions hereof, to make the
         Competitive Loan in respect of which its bid has been accepted.  After
         completing the notifications referred to in the immediately preceding
         sentence, the Auction Administration Agent shall (i) notify the
         Administrative Agent of each Competitive Bid that has been accepted,
         the amount thereof and the Competitive Bid Rate therefor and (ii)
         notify each Bank of the aggregate principal amount of all Competitive
         Bids accepted.

                 (f)         Upon receipt from the Administrative Agent of the
         LIBO Rate applicable to any Eurodollar Loan to be made by any Bank
         pursuant to a Competitive Bid that has been accepted by the Company
         pursuant to Section 2.2(d), the Auction Administration Agent shall
         notify such Bank of (i) the applicable LIBO Rate and (ii) the sum of
         the applicable LIBO Rate plus the Margin bid by such Bank.

                 (g)         No Competitive Bid Request shall be made within
         five Business Days of the date of any other Competitive Bid Request,
         unless the Company and the Auction Administration Agent shall mutually
         agree otherwise.

   30
                 (h)         If the Auction Administration Agent shall at any
         time have a Commitment hereunder and shall elect to submit a
         Competitive Bid in its capacity as a Bank, it shall submit such bid
         directly to the Company one quarter of an hour earlier than the latest
         time at which the other Banks are required to submit their bids to the
         Auction Administration Agent pursuant to paragraph (b) above.

                 (i)         All notices required by this Section 2.2 shall be
         made in accordance with Section 8.2.

         Section 2.3         Committed Borrowing Procedure.  In order to effect
a Committed Borrowing, the Company shall hand deliver or telecopy to the
Administrative Agent a duly completed request for Committed Borrowing,
substantially in the form of Exhibit A-2 hereto (a "Notice of Committed
Borrowing"), (i) in the case of Eurodollar Loans, not later than 10:00 a.m.,
Houston, Texas time, three Business Days before the Borrowing Date specified
for a proposed Committed Borrowing, and (ii) in the case of Alternate Base
Loans, not later than 10:00 a.m., Houston, Texas time, on the Business Day
which is the Borrowing Date specified for a proposed Committed Borrowing.  No
Fixed Rate Loan shall be requested or made pursuant to a Notice of Committed
Borrowing.  Such notice shall be irrevocable and shall in each case refer to
this Agreement and specify (x) whether the Loans then being requested are to be
Eurodollar Loans, or Alternate Base Loans, (y) the Borrowing Date of such Loans
(which shall be a Business Day) and the aggregate amount thereof (which shall
not be less than $10,000,000 and shall be an integral multiple of $1,000,000)
and (z) in the case of a Eurodollar Loan, the Interest Period with respect
thereto (which shall not end later than the Termination Date).  If no Interest
Period with respect to any Eurodollar Loan is specified in any such Notice of
Committed Borrowing, then the Company shall be deemed to have selected an
Interest Period of one month's duration.  Promptly, and in any event on the
same day the Administrative Agent receives a Notice of Committed Borrowing
pursuant to this Section 2.3 if such notice is received by 10:00 a.m., Houston,
Texas time on a Business Day and otherwise on the next succeeding Business Day,
the Administrative Agent shall advise the other Banks of such Notice of
Committed Borrowing and of each Bank's portion of the requested Committed
Borrowing by telecopier.  Each Committed Borrowing shall consist of Loans of
the same Type made on the same day and having the same Interest Period.

         Section 2.4         Refinancings; Conversions.

                 (a)         The Company may refinance all or any part of any
         Loan with a Loan of the same or a different type made pursuant to
         Section 2.2 or Section 2.3, subject to the conditions and limitations
         set forth herein and elsewhere in this Agreement, including, without
         limitation, refinancings of Competitive Loans with Committed Loans and
         Committed Loans with Competitive Loans.  Any Loan or part thereof so
         refinanced shall be deemed to be repaid in accordance with Section
         2.18 with the proceeds of a new Borrowing hereunder and the proceeds
         of the new Loan, to the extent they do not exceed the principal amount
         of the Loan being refinanced, shall not be paid by the Banks to the
         Administrative Agent or by the Administrative Agent to the Company
         pursuant to Section 2.7(c); provided, however, that (i) if the
         principal amount extended by a Bank in a refinancing is greater than
         the principal amount extended by such Bank in the Borrowing being
         refinanced, then such Bank shall pay such difference to the
         Administrative Agent for distribution to the Banks described in (ii)
         below, (ii) if the principal amount extended by a Bank in the
         Borrowing being refinanced is greater than the principal amount being
         extended by such Bank in the refinancing, the Administrative Agent
         shall return the difference to such Bank out of amounts received
         pursuant to (i) above, (iii) to the extent any Bank fails to pay the
         Administrative Agent amounts due from it pursuant to (i) above, any
         Loan or portion thereof being refinanced shall not be deemed repaid in
         accordance with Section 2.18 to the extent of such failure and the
         Company shall pay such amount to the Administrative Agent pursuant to
         Section 2.18 and (iv) to the extent the Company fails to pay to the
         Administrative Agent any amounts due in accordance with Section 2.18
         as a result of the failure of a Bank to pay the Administrative Agent
         any amounts due as described in (iii) above, the portion of any
         refinanced Loan deemed not repaid shall be deemed to be outstanding
         solely to the Bank which has failed to pay the Administrative Agent
         amounts due from it pursuant to (i) above to the full extent of such
         Bank's portion of such refinanced Loan.

                 (b)         Subject to the conditions and limitations set
         forth in this Agreement, the Company shall have the right from time to
         time to convert all or part of one Type of Committed Loan





                                      -26-
   32
         into another Type of Committed Loan or to continue all or a part of
         any Committed Loan that is a Eurodollar Loan from one Interest Period
         to another Interest Period by giving the Administrative Agent written
         notice (by means of a Notice of Committed Borrowing) (i) in the case
         of Eurodollar Loans, not later than 10:00 a.m., Houston, Texas time,
         three Business Days before the date specified for such proposed
         conversion or continuation, and (ii) in the case of Alternate Base
         Loans, not later than 10:00 a.m., Houston, Texas time, on the Business
         Day which is the date specified for such proposed conversion or
         continuation.  Such notice shall specify (A) the proposed date for
         conversion or continuation, (B) the amount of the Committed Loan to be
         converted or continued, (C) in the case of conversions, the Type of
         Committed Loan to be converted into, and (D) in the case of a
         continuation of or conversion into a Eurodollar Loan, the duration of
         the Interest Period applicable thereto; provided that (1) Eurodollar
         Loans may be converted only on the last day of the applicable Interest
         Period, (2) except for conversions to Alternate Base Loans, no
         conversion shall be made while a Default or Event of Default has
         occurred and is continuing and no continuations of any Eurodollar Loan
         from one Interest Period to another Interest Period shall be made
         while a Default or Event of Default has occurred and is continuing,
         unless such conversion or continuation has been approved by Majority
         Committed Banks, and (3) each such conversion or continuation shall be
         in an amount not less than $10,000,000 and shall be an integral
         multiple of $1,000,000.  All notices given under this Section shall be
         irrevocable.  If the Company shall fail to give the Administrative
         Agent the notice as specified above for continuation or conversion of
         a Eurodollar Loan prior to the end of the Interest Period with respect
         thereto, such Eurodollar Loan shall automatically be converted into an
         Alternate Base Loan on the last day of the Interest Period for such
         Eurodollar Loan.

         Section 2.5         Fees.  The Company agrees to pay to each Bank,
through the Administrative Agent, on each Quarterly Payment Date and on the
Termination Date, in immediately available funds, a facility fee (a "Facility
Fee") calculated by multiplying the Facility Fee Percentage by the amount of
the average daily Commitment of such Bank, whether used or unused, during the
preceding three-month period (or shorter period commencing with the Effective
Date and/or ending with the Termination Date).  All





                                      -27-
   33
Facility Fees shall be computed by the Administrative Agent on the basis of the
actual number of days elapsed in a year of 360 days, and shall be conclusive
and binding for all purposes, absent manifest error.  The Facility Fee due to
each Bank shall commence to accrue on the Effective Date and shall cease to
accrue on the earlier of the Termination Date and the termination of the
Commitment of such Bank as provided herein.  Notwithstanding the foregoing, in
no event shall any Bank be permitted to receive any compensation hereunder
constituting interest in excess of the Highest Lawful Rate.

         Section 2.6         Termination and Reduction of Commitments.

                 (a)         Subject to Section 2.12(b), the Company may
         permanently terminate, or from time to time in part permanently
         reduce, the Total Commitment, in each case upon at least three
         Business Days' prior written notice to the Administrative Agent (who
         shall promptly forward a copy thereof to each Bank and the Auction
         Administration Agent).  Such notice shall specify the date and the
         amount of the termination or reduction of the Total Commitment.  Each
         such partial reduction of the Total Commitment shall be in a minimum
         aggregate principal amount of $10,000,000 and in an integral multiple
         of $1,000,000.

                 (b)         On the Termination Date the Total Commitment shall
         be zero.

                 (c)         Each reduction in the Total Commitment pursuant to
         this Section 2.6 shall be made ratably among the Banks in accordance
         with their respective Commitments. Simultaneously with any termination
         of Commitments pursuant to this Section, the Company shall pay to the
         Administrative Agent for the accounts of the Banks the Facility Fees
         on the amount of the Total Commitment so terminated, accrued through
         the date of such termination.

         Section 2.7         Loans.

                 (a)         Each Borrowing made by the Company on any date
         shall be (i) in the case of Competitive Loans, in an integral multiple
         of $1,000,000 and in a minimum aggregate principal amount of
         $5,000,000 and (ii) in the case of Committed Loans, in an integral
         multiple of $1,000,000 and in a minimum





                                      -28-
   34
         aggregate principal amount of $10,000,000.  Competitive Loans shall be
         made by the Banks in accordance with Section 2.2(d), and Committed
         Loans shall be made by the Banks ratably in accordance with their
         respective Commitments on the Borrowing Date of the Committed
         Borrowing; provided, however, that the failure of any Bank to make any
         Loan shall not in itself relieve any other Bank of its obligation to
         lend hereunder.

                 (b)         Each Competitive Loan shall be a Eurodollar Loan
         or a Fixed Rate Loan, and each Committed Loan shall be a Eurodollar
         Loan or an Alternate Base Loan, as the Company may request subject to
         and in accordance with Section 2.2, Section 2.3 or Section 2.4(b), as
         applicable.  Each Bank may at its option make any Eurodollar Loan by
         causing a foreign branch or Affiliate of such Bank to make such Loan;
         provided, however, that any exercise of such option shall not affect
         the obligation of the Company to repay such Loan in accordance with
         the terms of this Agreement.  Loans of more than one interest rate
         option may be outstanding at the same time; provided, however, that
         the Company shall not be entitled to request any Loan which, if made,
         would result in an aggregate of more than ten separate Interest
         Periods being outstanding hereunder at any one time.  For purposes of
         the foregoing, Loans having different Interest Periods, regardless of
         whether they commence on the same date, shall be considered separate
         Loans.

                 (c)         Subject to Section 2.4, each Bank shall make its
         portion of each Competitive Borrowing and each Committed Borrowing on
         the proposed Borrowing Date thereof by paying the amount required to
         the Administrative Agent at the Principal Office in immediately
         available funds not later than 12:00 noon, Houston, Texas time, and
         the Administrative Agent shall by 2:00 p.m., Houston, Texas time,
         credit the amounts so received to the general deposit account of the
         Company with the Administrative Agent or, if Loans are not made on
         such date because any condition precedent to a Borrowing herein
         specified shall not have been met, return the amounts so received to
         the respective Banks as soon as practicable; provided, however, if and
         to the extent the Administrative Agent fails to return any such
         amounts to a Bank on the Borrowing Date for such Borrowing, the
         Administrative Agent shall pay interest on such unreturned amounts,
         for each day from such Borrowing Date to the date such amounts are
         returned to such Bank, at the Federal Funds Effective Rate.





                                      -29-
   35
                 (d)         The outstanding principal amount of each
         Competitive Loan shall be due and payable on the last day of the
         Interest Period applicable to such Competitive Loan, and the
         outstanding principal balance of each Committed Loan shall be due and
         payable on the Termination Date.

         Section 2.8         Loan Accounts.

                 (a)         The Loans made by each Bank shall be evidenced by
         one or more loan accounts or records maintained by such Bank in the
         ordinary course of business.  Absent manifest error, the loan accounts
         or records maintained by the Administrative Agent and each Bank shall
         be prima facie evidence of the amount of the Loans made by the Banks
         to the Company and the interest and payments thereon.  Any failure so
         to record or any error in doing so shall not, however, limit or
         otherwise affect the obligation of the Company hereunder to pay any
         amount owing with respect to the Loans.

                 (b)         Upon the request of any Bank made through the
         Administrative Agent, the Loans made by such Bank may be evidenced by
         one or more Notes, instead of or in addition to loan accounts, and
         upon any such request the Company shall execute and deliver such Notes
         to such Bank.  Each such Bank shall, and is hereby authorized by the
         Company to, endorse on the schedule attached to the relevant Note held
         by such Bank (or on a continuation of such schedule attached to each
         such Note and made a part thereof) or in its records relating to such
         Note an appropriate notation evidencing the date and amount of each
         Competitive Loan or Committed Loan, as applicable, of such Bank, each
         payment or prepayment of principal of any Competitive Loan or
         Committed Loan, as applicable, and the other information provided for
         on such schedule.  The failure of any Bank to make such a notation or
         any error therein shall not in any manner affect the obligation of the
         Company to repay the Competitive Loans or Committed Loans, as
         applicable, made by such Bank in accordance with the terms of the
         relevant Note.

         Section 2.9         Interest on Loans.

                 (a)         Subject to the provisions of Section 2.10, each
         Eurodollar Loan shall bear interest at a rate per annum (computed on
         the basis of the actual number of days elapsed over a year of 360
         days) equal to the lesser of (i) the Highest Lawful Rate and (ii) the
         LIBO Rate for the Interest Period in effect for such Loan (A) plus or
         minus, as the case may be, in the case of each Competitive Loan, the
         Margin specified by a Bank with respect to such Loan in its
         Competitive Bid submitted pursuant to Section 2.2(b) or (B) plus, in
         the case of each Committed Loan, the Applicable Margin.  Interest on
         each Eurodollar Loan shall be payable on each Interest Payment Date
         applicable thereto.  The applicable LIBO Rate for each Interest Period
         shall be determined by the Administrative Agent, and such
         determination shall be conclusive absent manifest error.

                 (b)         Subject to the provisions of Section 2.10, each
         Alternate Base Loan shall bear interest at the rate per annum equal to
         the lesser of (i) the Highest Lawful Rate and (ii) the Alternate Base
         Rate (if the Alternate Base Rate is based on the Prime Rate, computed
         on the basis of the actual number of days elapsed over a year of 365
         or 366 days, as the case may be; if the Alternate Base Rate is based
         on the Federal Funds Effective Rate, computed on the basis of the
         actual number of days elapsed over a year of 360 days).  Interest on
         each Alternate Base Loan shall be payable on each Interest Payment
         Date applicable thereto.  The applicable Alternate Base Rate shall be
         determined by the Administrative Agent, and such determination shall
         be conclusive absent manifest error.

                 (c)         Subject to the provisions of Section 2.10, each
         Fixed Rate Loan shall bear interest at a rate per annum (computed on
         the basis of the actual number of days elapsed over a year of 360
         days) equal to the fixed rate of interest offered by the Bank making
         such Loan and accepted by the Company pursuant to Section 2.2.
         Interest on each Fixed Rate Loan shall be payable on each Interest
         Payment Date applicable thereto.

                 (d)         The Company shall pay to the Administrative Agent
         for the account of each Bank that has made a Eurodollar Loan to the
         Company, so long as such Bank shall be required under





                                      -31-
   37
         regulations of the Board to maintain reserves with respect to
         liabilities or assets consisting of or including Eurocurrency
         Liabilities, additional interest on the unpaid principal amount of
         each such Eurodollar Loan of such Bank, from the date of such Loan
         until such principal amount is paid in full, at an interest rate per
         annum for such number of days during the Interest Period for such Loan
         as shall be pertinent equal to the remainder obtained by subtracting
         (i) the LIBO Rate for such Interest Period from (ii) the rate obtained
         by dividing such LIBO Rate referred to in clause (i) above by that
         percentage equal to 100% minus the Reserve Percentage of such Bank for
         such Interest Period, payable on the next Interest Payment Date
         applicable to such Loan; provided, however, in no event shall any Bank
         be permitted to receive interest hereunder in excess of the Highest
         Lawful Rate.  Such additional interest shall be determined by such
         Bank as, if and to the extent incurred, and shall be payable as
         aforesaid upon notification thereof by such Bank to the Company
         through the Administrative Agent.  Each determination by a Bank of
         additional interest under this Section 2.9(d) shall be conclusive and
         binding for all purposes in the absence of manifest error.

         Section 2.10        Interest on Overdue Amounts.  If the Company shall
default in the payment of the principal of or interest on any Loan or any other
amount becoming due hereunder, the Company shall on demand from time to time
pay interest, to the extent permitted by Law, on such defaulted amount up to
(but not including) the date of actual payment (after as well as before
judgment) at a rate per annum equal to the lesser of (i) the Highest Lawful
Rate and (ii) the Agreed Maximum Rate (if the Alternate Base Rate is based on
the Prime Rate, computed on the basis of the actual number of days elapsed over
a year of 365 or 366 days, as the case may be; if the Alternate Base Rate is
based on the Federal Funds Effective Rate, computed on the basis of the actual
number of days elapsed over a year of 360 days).

         Section 2.11        Alternate Rate of Interest.  In the event, and on
each occasion, that on the day two Business Days prior to the commencement of
any Interest Period for a Eurodollar Loan that is a Committed Loan, the
Administrative Agent shall have determined that dollar deposits in the amount
of the requested principal amount of such Eurodollar Loan are not generally
available in the Eurodollar Interbank Market, or that dollar deposits are not





                                      -32-
   38
generally available in the Eurodollar Interbank Market for the requested
Interest Period, or that the rate at which such dollar deposits are being
offered will not adequately and fairly reflect the cost to any Bank of making
or maintaining such Eurodollar Loan during such Interest Period, or that
reasonable means do not exist for ascertaining the LIBO Rate, the
Administrative Agent shall, as soon as practicable thereafter, give telecopy
notice of such determination to the Company, the Auction Administration Agent,
and the Banks.  In the event of any such determination, any request by the
Company for a Eurodollar Loan that is a Committed Loan shall, until the
circumstances giving rise to such notice no longer exist, be deemed to be a
request for an Alternate Base Loan.  Each determination by the Administrative
Agent hereunder shall be conclusive absent manifest error.

         Section 2.12        Prepayment of Loans.

                 (a)         Prior to the Termination Date, the Company shall
         have the right at any time to prepay any Committed Borrowing, in whole
         or in part, subject to the requirements of Section 2.15 or Section
         2.16 but otherwise without premium or penalty, upon at least five
         Business Days prior written notice to the Administrative Agent;
         provided, however, that each such partial prepayment shall be in an
         integral multiple of $1,000,000 and in a minimum aggregate principal
         amount of $5,000,000.  Each notice of prepayment shall specify the
         prepayment date and the aggregate principal amount of each Borrowing
         to be prepaid, shall be irrevocable and shall commit the Company to
         prepay such Borrowing by the amount stated therein.  The Company shall
         not have the right to prepay any Competitive Borrowing.

                 (b)         On the date of any termination or reduction of the
         Total Commitment pursuant to Section 2.6(a), the Company shall pay or
         prepay so much of the Loans as shall be necessary in order that the
         aggregate principal amount of the Loans outstanding will not exceed
         the Total Commitment following such termination or reduction.  Subject
         to the foregoing, any such payment or prepayment shall be applied to
         such Borrowing or Borrowings as the Company shall select.  All
         prepayments under this paragraph shall be subject to Section 2.15 and
         Section 2.16.





                                      -33-
   39
                 (c)         All prepayments under this Section 2.12 shall be
         accompanied by accrued interest on the principal amount being prepaid
         to the date of prepayment.

         Section 2.13        Reserve Requirements; Change in Circumstances.

                 (a)         Notwithstanding any other provision herein, if
         after the date of this Agreement any Regulatory Change (i) shall
         change the basis of taxation of payments to any Bank of the principal
         of or interest on any Eurodollar Loan or Fixed Rate Loan made by such
         Bank or any other fees or amounts payable hereunder (other than (x)
         Taxes imposed on or measured by the capital, receipts or franchises of
         such Bank or the overall gross or net income of such Bank by the
         jurisdiction in which such Bank has its principal office or by any
         political subdivision or taxing authority therein (or any Tax which is
         enacted or adopted by such jurisdiction, political subdivision, or
         taxing authority as a direct substitute for any such Taxes) or (y) any
         Tax, assessment, or other governmental charge that would not have been
         imposed but for the failure of any Bank to comply with any
         certification, information, documentation, or other reporting
         requirement), (ii) shall impose, modify, or deem applicable any
         reserve, special deposit, or similar requirement with respect to any
         Eurodollar Loan against assets of, deposits with or for the account
         of, or credit extended by, such Bank under this Agreement (without
         duplication of any amounts paid pursuant to Section 2.9(d)), or (iii)
         with respect to any Eurodollar Loan, shall impose on such Bank or the
         Eurodollar Interbank Market any other condition affecting this
         Agreement or any Eurodollar Loan made by such Bank, and the result of
         any of the foregoing shall be to materially increase the actual cost
         to such Bank of maintaining its Commitment or of making or maintaining
         any Eurodollar Loan or Fixed Rate Loan or to materially reduce the
         amount of any sum received or receivable by such Bank hereunder
         (whether of principal, interest, or otherwise) in respect thereof,
         then the Company shall pay to the Administrative Agent for the account
         of such Bank, within ten days following delivery to the Company of the
         certificate specified in paragraph (c) below by such Bank, such
         additional amount or amounts as will reimburse such Bank for such
         increase or reduction to such Bank to the extent reasonably allocable
         to this Agreement.  Notwithstanding the foregoing, in no event shall
         any Bank be permitted to receive any payment hereunder constituting
         interest in excess of the Highest Lawful Rate.





                                      -34-
   40
                 (b)         If any Bank shall have determined in good faith
         that any Regulatory Change regarding capital adequacy or compliance by
         any Bank (or its parent or any lending office of such Bank) with any
         request or directive regarding capital adequacy (whether or not having
         the force of Law) of any Tribunal, monetary authority, central bank,
         or comparable agency, has or would have the effect of reducing the
         rate of return on such Bank's (or its parent's) capital as a
         consequence of its obligations hereunder to a level below that which
         such Bank (or its parent) could have achieved but for such Regulatory
         Change, or compliance (taking into consideration such Bank's policies
         with respect to capital adequacy) by an amount deemed by such Bank to
         be material, then from time to time, the Company shall pay to the
         Administrative Agent for the account of such Bank, within ten days
         following delivery to the Company of the certificate specified in
         paragraph (c) below by such Bank, such additional amount or amounts as
         will reimburse such Bank (or its parent) for such reduction.
         Notwithstanding the foregoing, in no event shall any Bank be permitted
         to receive any payment hereunder constituting interest in excess of
         the Highest Lawful Rate.

                 (c)         Each Bank shall notify the Company of any event
         occurring after the date hereof entitling such Bank to compensation
         under paragraph (a) or (b) of this Section 2.13 (together with a good
         faith estimate of the amounts it would be entitled to claim in respect
         of such event) as promptly as practicable, but in any event on or
         before the date which is 60 days after the related Regulatory Change
         or other event; provided that (i) if such Bank fails to give such
         notice by such date, such Bank shall, with respect to compensation
         payable pursuant to paragraph (a) or (b) of this Section 2.13 in
         respect of any costs resulting from such Regulatory Change or other
         event, only be entitled to payment under paragraph (a) or (b) of this
         Section 2.13 for costs incurred from and after the date of such notice
         and (ii) such Bank will take such reasonable actions, if any
         (including the designation of a different Applicable Lending Office
         for the Loans of such Bank affected by such event) to avoid the need
         for, or reduce the amount of, such compensation so long as such
         actions will not, in the reasonable opinion of such Bank,





                                      -35-
   41
         be materially disadvantageous to such Bank.  A certificate of a Bank
         setting forth in reasonable detail (i) the Regulatory Change or other
         event giving rise to any costs, (ii) such amount or amounts as shall
         be necessary to reimburse such Bank (or participating banks or other
         entities pursuant to Section 8.11) as specified in paragraph (a) or
         (b) of this Section 2.13, as the case may be, and (iii) the
         calculation of such amount or amounts, shall be delivered to the
         Company (with a copy to the Administrative Agent) promptly after such
         Bank determines it is entitled to payment under this Section 2.13, and
         shall be conclusive and binding absent manifest error.  In preparing
         such certificate, such Bank may employ such assumptions and
         allocations of costs and expenses as it shall in good faith deem
         reasonable and may use any reasonable averaging and attribution
         method.

                 (d)         In the event any Bank shall seek payment pursuant
         to this Section 2.13 or the events contemplated under Section 2.11 or
         Section 2.14 shall have occurred with respect to any Bank, the Company
         may, provided no Event of Default has occurred and is continuing, give
         notice to such Bank (with copies to the Agents) that it wishes to seek
         one or more Eligible Assignees (which may be one or more of the Banks,
         but which may not be a Person who would be entitled at such time to
         claim payment pursuant to this Section 2.13 or with respect to which
         any of the events contemplated under Section 2.11 or Section 2.14
         would exist at such time if such Person were a Bank under this
         Agreement) to assume the Commitment of such Bank and to purchase its
         outstanding Loans and Notes (if any).  Each Bank requesting payment
         pursuant to this Section 2.13, or with respect to which any of the
         events contemplated under Section 2.11 or Section 2.14 have occurred,
         agrees to sell its Commitment, Loans, Notes (if any), and interest in
         this Agreement and the other Loan Papers pursuant to Section 8.11(c)
         to any such Eligible Assignee approved by the Company and the
         Administrative Agent for an amount equal to the sum of the outstanding
         unpaid principal of and accrued interest on such Loans and Notes (if
         any) plus all other fees and amounts (including, without limitation,
         any payment claimed by such Bank under this Section 2.13 and as to
         which such Bank has delivered the certificate required by Section
         2.13(c) on or before the date such Commitment, Loans, and Notes (if 
         any) are purchased) due such Bank hereunder calculated, in each case, 
         to the date such Commitment, Loans, 





                                      -36-
   42
         Notes (if any) and interest are purchased, whereupon such Bank shall
         have no further Commitment or other obligation to the Company hereunder
         or under any other Loan Paper.

                 (e)         Notwithstanding anything herein to the contrary,
         no Bank or participant shall be entitled to any payment under this
         Section 2.13 with respect to any Competitive Loan.

                 (f)         Without prejudice to the survival of any other
         obligations of the Company hereunder, the obligations of the Company
         under this Section 2.13 shall survive for one year after the
         termination of this Agreement and/or the payment or assignment of any
         of the Loans or Notes.

         Section 2.14        Change in Legality.

                 (a)         Notwithstanding anything to the contrary herein
         contained, if any Regulatory Change shall make it unlawful for any
         Bank to make or maintain any Eurodollar Loan or to give effect to its
         obligations in respect of Eurodollar Loans as contemplated hereby,
         then, by prompt written notice to the Company and to the
         Administrative Agent and the Auction Administration Agent, such Bank
         may:

                             (i)          declare that Eurodollar Loans will
                 not thereafter be made by such Bank hereunder, whereupon the
                 Company shall be prohibited from requesting Eurodollar Loans
                 from such Bank hereunder unless such declaration is
                 subsequently withdrawn; and

                             (ii)         if such unlawfulness shall be
                 effective prior to the end of any Interest Period of an
                 outstanding Eurodollar Loan, require that all outstanding
                 Eurodollar Loans with such Interest Periods made by it be
                 converted to Alternate Base Loans, in which event (A) all such
                 Eurodollar Loans shall be automatically converted to Alternate
                 Base Loans as of the effective date of such notice as provided
                 in paragraph (b) below and (B) all payments and prepayments of
                 principal which would otherwise have been applied to repay the
                 converted Eurodollar Loans shall instead be applied to repay
                 the Alternate Base Loans resulting from the conversion of such
                 Eurodollar Loans.





                                      -37-
   43
                 (b)         For purposes of this Section 2.14, a notice to the
         Company (with a copy to the Administrative Agent and the Auction
         Administration Agent) by any Bank pursuant to paragraph (a) above
         shall be effective on the date of receipt thereof by the Company.  Any
         Bank having furnished such a notice agrees to withdraw the same
         promptly following any Regulatory Change that makes it lawful for such
         Bank to make and maintain Eurodollar Loans.

                 (c)         If, with respect to any Bank, a condition arises
         or an event occurs which would, or would upon the giving of notice,
         result in the payment of amounts pursuant to Section 2.13 or permit
         such Bank, pursuant to this Section 2.14, to suspend its obligation to
         make Eurodollar Loans, such Bank, promptly upon becoming aware of the
         same, shall notify the Company thereof and shall take such steps as
         may reasonably be available to it (including, without limitation,
         changing its Applicable Lending Office) to mitigate the effects of
         such condition or event, provided that such Bank shall be under no
         obligation to take any step that, in its good faith opinion, would (a)
         result in its incurring any additional costs in performing its
         obligations hereunder and under any outstanding Loan (unless the
         Company has notified such Bank of the Company's agreement to reimburse
         it for the same) or (b) be otherwise adverse to such Bank in a
         material respect.

         Section 2.15        INDEMNITY.  THE COMPANY SHALL INDEMNIFY EACH BANK
AGAINST ANY LOSS OR REASONABLE EXPENSE WHICH SUCH BANK MAY SUSTAIN OR INCUR AS
A CONSEQUENCE OF (A) ANY FAILURE BY THE COMPANY TO FULFILL ON THE DATE OF ANY
BORROWING HEREUNDER THE APPLICABLE CONDITIONS SET FORTH IN ARTICLE III, (B) ANY
FAILURE BY THE COMPANY TO BORROW HEREUNDER AFTER A NOTICE OF COMMITTED
BORROWING PURSUANT TO ARTICLE II HAS BEEN GIVEN OR AFTER COMPETITIVE BIDS HAVE
BEEN ACCEPTED, (C) ANY PAYMENT, PREPAYMENT, OR CONVERSION OF A EURODOLLAR LOAN
OR FIXED RATE LOAN REQUIRED BY ANY OTHER PROVISION OF THIS AGREEMENT OR
OTHERWISE MADE ON A DATE OTHER THAN THE LAST DAY OF THE APPLICABLE INTEREST
PERIOD FOR ANY REASON, INCLUDING WITHOUT LIMITATION THE ACCELERATION OF
OUTSTANDING LOANS AS A RESULT OF ANY EVENT OF DEFAULT, (D) ANY FAILURE BY THE
COMPANY FOR ANY REASON (INCLUDING WITHOUT LIMITATION THE EXISTENCE OF A DEFAULT
OR AN EVENT OF DEFAULT) TO PAY, PREPAY OR CONVERT A EURODOLLAR LOAN ON THE DATE
FOR SUCH PAYMENT, PREPAYMENT OR CONVERSION, SPECIFIED IN THE RELEVANT NOTICE OF
PAYMENT, PREPAYMENT OR CONVERSION UNDER





                                      -38-
   44
THIS AGREEMENT.  THE INDEMNITY OF THE COMPANY PURSUANT TO THE IMMEDIATELY
PRECEDING SENTENCE SHALL INCLUDE, BUT NOT BE LIMITED TO, ANY LOSS OR REASONABLE
EXPENSE SUSTAINED OR INCURRED OR TO BE SUSTAINED OR INCURRED IN LIQUIDATING OR
EMPLOYING DEPOSITS FROM THIRD PARTIES ACQUIRED TO EFFECT OR MAINTAIN SUCH LOAN
OR ANY PART THEREOF AS A EURODOLLAR LOAN OR FIXED RATE LOAN.  SUCH LOSS OR
REASONABLE EXPENSE SHALL INCLUDE, WITHOUT LIMITATION, AN AMOUNT EQUAL TO THE
EXCESS, IF ANY, AS REASONABLY DETERMINED BY EACH BANK OF (I) ITS COST OF
OBTAINING THE FUNDS FOR THE LOAN BEING PAID, PREPAID, OR CONVERTED OR NOT
BORROWED, PAID, PREPAID OR CONVERTED (BASED ON THE LIBO RATE OR, IN THE CASE OF
A FIXED RATE LOAN, THE FIXED RATE OF INTEREST APPLICABLE THERETO) FOR THE
PERIOD FROM THE DATE OF SUCH PAYMENT, PREPAYMENT, OR CONVERSION OR FAILURE TO
BORROW, PAY, PREPAY OR CONVERT TO THE LAST DAY OF THE INTEREST PERIOD FOR SUCH
LOAN (OR, IN THE CASE OF A FAILURE TO BORROW, PAY, PREPAY OR CONVERT, THE
INTEREST PERIOD FOR THE LOAN WHICH WOULD HAVE COMMENCED ON THE DATE OF SUCH
FAILURE TO BORROW, PAY, PREPAY OR CONVERT) OVER (II) THE AMOUNT OF INTEREST (AS
REASONABLY DETERMINED BY SUCH BANK) THAT WOULD BE REALIZED BY SUCH BANK IN
REEMPLOYING THE FUNDS SO PAID, PREPAID, OR CONVERTED OR NOT BORROWED, PAID,
PREPAID OR CONVERTED FOR SUCH PERIOD OR INTEREST PERIOD, AS THE CASE MAY BE.  A
CERTIFICATE OF EACH BANK SETTING FORTH ANY AMOUNT OR AMOUNTS AND, IN REASONABLE
DETAIL, THE COMPUTATIONS THEREOF, WHICH SUCH BANK IS ENTITLED TO RECEIVE
PURSUANT TO THIS SECTION 2.15 SHALL BE DELIVERED TO THE COMPANY (WITH A COPY TO
THE ADMINISTRATIVE AGENT) AND SHALL BE CONCLUSIVE, IF MADE IN GOOD FAITH,
ABSENT MANIFEST ERROR.  THE COMPANY SHALL PAY TO THE ADMINISTRATIVE AGENT FOR
THE ACCOUNT OF EACH BANK THE AMOUNT SHOWN AS DUE ON ANY CERTIFICATE WITHIN 30
DAYS AFTER ITS RECEIPT OF THE SAME.  NOTWITHSTANDING THE FOREGOING, IN NO EVENT
SHALL ANY BANK BE PERMITTED TO RECEIVE ANY COMPENSATION HEREUNDER CONSTITUTING
INTEREST IN EXCESS OF THE HIGHEST LAWFUL RATE.  WITHOUT PREJUDICE TO THE
SURVIVAL OF ANY OTHER OBLIGATIONS OF THE COMPANY HEREUNDER, THE OBLIGATIONS OF
THE COMPANY UNDER THIS SECTION 2.15 SHALL SURVIVE FOR ONE YEAR AFTER THE
TERMINATION OF THIS AGREEMENT AND/OR THE PAYMENT OR ASSIGNMENT OF ANY OF THE
LOANS OR NOTES.

         Section 2.16        Pro Rata Treatment.  Except as permitted under
Section 2.9(d), Section 2.13(c) and Section 2.15 with respect to interest, (a)
each payment or prepayment of principal and each payment of interest with
respect to a Competitive Borrowing (at a particular Competitive Bid Rate) or a
Committed Borrowing shall be made pro rata among the Banks in accordance with
the respective





                                      -39-
   45
principal amounts of the Loans extended by each Bank, if any, with respect to
such Competitive Borrowing or Committed Borrowing, and (b) conversions of
Committed Loans to Committed Loans of another Type, continuations of Committed
Loans that are Eurodollar Loans from one Interest Period to another Interest
Period, refinancings of Competitive Loans with Committed Loans, and Committed
Loans which are not refinancings of other Loans shall be made pro rata among
the Banks in accordance with their respective Commitments.

         Section 2.17        Sharing of Setoffs.  Each Bank agrees that if it
shall through the exercise of a right of banker's lien, setoff, or counterclaim
against the Company (pursuant to Section 8.6 or otherwise), including, but not
limited to, a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Bank under any applicable Debtor Relief Law or
otherwise, obtain payment (voluntary or involuntary) in respect of the
Committed Loans held by it (other than pursuant to Section 2.9(d), Section
2.13, or Section 2.15) as a result of which the unpaid principal portion of the
Committed Loans held by it shall be proportionately less than the unpaid
principal portion of the Committed Loans held by any other Bank, it shall be
deemed to have simultaneously purchased from such other Bank a participation in
the Committed Loans held by such other Bank, so that the aggregate unpaid
principal amount of the Committed Loans and participations in Committed Loans
pursuant to this Section 2.17 held by each Bank shall be in the same proportion
to the aggregate unpaid principal amount of all Committed Loans then
outstanding as the principal amount of the Committed Loans held by it prior to
such exercise of banker's lien, setoff, or counterclaim was to the principal
amount of all Committed Loans outstanding prior to such exercise of banker's
lien, setoff, or counterclaim; provided, however, that if any such purchase or
purchases or adjustments shall be made pursuant to this Section 2.17 and the
payment giving rise thereto shall thereafter be recovered, such purchase or
purchases or adjustments shall be rescinded to the extent of such recovery and
the purchase price or prices or adjustment restored without interest.  The
Company expressly consents to the foregoing arrangements and agrees that any
Bank holding a participation in a Committed Loan deemed to have been so
purchased may exercise any and all rights of banker's lien, setoff, or
counterclaim with respect to any and all moneys owing by the Company to such
Bank as fully as if such Bank had made a Committed Loan directly to the Company
in the amount of such participation.

         Section 2.18        Payments.

                 (a)         The Company shall make each payment hereunder and
         under any instrument delivered hereunder not later than 11:00 a.m.
         (Houston, Texas time) on the day when due in dollars to the
         Administrative Agent at its Principal Office for the account of the
         Banks, in federal or other immediately available funds.  The
         Administrative Agent will promptly thereafter cause to be distributed
         like funds relating to the payment of principal of or interest on
         Committed Loans (other than pursuant to Section 2.9(d), Section 2.13,
         and Section 2.15) or Facility Fees ratably to the Banks and like funds
         relating to the payment of any other amount (including, without
         limitation, payments of principal or interest on Competitive Loans
         which are not made ratably to the Banks) payable to any Bank to such
         Bank for the account of its Applicable Lending Office, in each case to
         be applied in accordance with the terms of this Agreement.

                 (b)         Whenever any payment hereunder or under any Note
         shall be stated to be due on a day other than a Business Day, such
         payment shall be made on the next succeeding Business Day, and such
         extension of time shall in all such cases be included in the
         computation of payment of interest or Facility Fee, as the case may
         be; provided, however, if such extension would cause payment of
         interest on or principal of a Eurodollar Loan to be made in the next
         following calendar month, such payment shall be made on the next
         preceding Business Day.

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

                 (d)         Except as expressly provided in Section 2.19, all
         payments (whether of principal, interest, fees, reimbursements, or
         otherwise) by the Company under this Agreement shall be made without
         setoff or counterclaim and shall be made free and clear of and without
         deduction for any present or future Tax, levy, impost, or any other
         charge, if any, of any nature whatsoever now or hereafter imposed by
         any Tribunal.  Except as otherwise provided in Section 2.19, if the
         making of such payments by the Company is prohibited by Law unless
         such a Tax, levy, impost, or other charge is deducted or withheld
         therefrom, the Company shall pay to the Administrative Agent, on the
         date of each such payment, such additional amounts (without
         duplication of any other amounts required to be paid by the Company
         pursuant to Section 2.13) as may be necessary in order that the net
         amounts received by the Banks after such deduction or withholding
         shall equal the amounts which would have been received if such
         deduction or withholding were not required.  The Company shall confirm
         that all applicable Taxes, if any, imposed on this Agreement or
         transactions hereunder shall have been properly and legally paid by it
         to the appropriate taxing authorities by sending official Tax receipts
         or notarized copies of such receipts to the Administrative Agent
         within 30 days after payment of any applicable Tax.

         Section 2.19        Tax Forms.  With respect to each Bank which is
organized under the Laws of a jurisdiction outside the United States, within 30
days after the Execution Date, and from time to time thereafter if requested by
the Company or the Administrative Agent, or as otherwise required by law, each
such Bank shall provide the Administrative Agent and the Company with the forms
prescribed by the Internal Revenue Service of the United States certifying as
to such Bank's status for purposes of determining exemption from United States
withholding Taxes with respect to all payments to be made to such Bank
hereunder or other documents satisfactory to the Company and the Administrative
Agent indicating that all payments to be made to such Bank hereunder are
subject to such Tax at a rate reduced by an applicable Tax treaty.  Unless the
Company and the Administrative Agent have received such forms or such documents
indicating that payments hereunder are not subject to United States withholding
Tax, the Company or the Administrative





                                      -42-
   48
Agent (after notice from the Administrative Agent to such Bank of such
non-receipt) shall withhold Taxes from such payments at the applicable
statutory rate (or any reduced applicable Tax treaty rate) in the case of
payments to or for any Bank organized under the Laws of a jurisdiction outside
the United States.

         Section 2.20        Calculation of LIBO Rates.  The provisions of this
Agreement relating to calculation of the LIBO Rate are included only for the
purpose of determining the rate of interest or other amounts to be paid
hereunder that are based upon such rate, it being understood that each Bank
shall be entitled to fund and maintain its funding of all or any part of a
Eurodollar Loan as it sees fit.  All such determinations hereunder, however,
shall be made as if each Bank had actually funded and maintained funding of
each Eurodollar Loan through the purchase in the Eurodollar InterBank Market of
one or more eurodollar deposits in an amount equal to the principal amount of
such Loan and having a maturity corresponding to the Interest Period for such
Loan.

         Section 2.21        Booking Loans.  Subject to Section 2.19, any Bank
may make, carry, or, transfer Loans at, to, or for the account of any of its
branch offices or the office of any Affiliate.

         Section 2.22        Quotation of Rates.  It is hereby acknowledged
that the Company may call the Administrative Agent on or before the date on
which notice of a Borrowing is to be delivered by the Company in order to
receive an indication of the rate or rates then in effect, but that such
projection shall not be binding upon the Administrative Agent or any Bank nor
affect the rate of interest which thereafter is actually in effect when the
election is made.

         Material Subsidiaries is duly qualified as a foreign corporation to do
         business and is in good standing in every jurisdiction where the
         character of its Properties or nature of its activities make such
         qualification necessary, except where the failure to be so qualified
         or in good standing would not have a Material Adverse Effect; and

                 (d)         On the Execution Date, the Company has no Material
         Subsidiaries.

         Section 4.2         Financial Statements.  The Current Financials

         Section 4.7         Taxes.  To the extent that failure to do so would
have a Material Adverse Effect, the Company and each of its Material
Subsidiaries has filed all Tax returns or reports required of it and has paid
all Tax liability shown thereon as due to the extent the same has become due
and before it may have become delinquent (except to the extent being contested
in good faith by appropriate proceedings and for which adequate reserves have
been established).  The federal income tax liability of the Company and its
Subsidiaries has been audited by the Internal Revenue Service and has been
finally determined and satisfied for all taxable years up to and including the
taxable year ended December 31, 1986.

         Section 4.8         Approvals Required.  Neither the execution and
delivery of this Agreement and the other Loan Papers by the Company, nor the
consummation by the Company of any of the transactions contemplated hereby or
thereby requires the consent or approval of, the giving of notice to, or the
registration, recording, or filing of any document with, or the taking of any
other action in respect of any Tribunal except for the routine filing of copies

Exchange Commission, except for any of the foregoing required of any Bank or

repair, overhaul, improve, and rebuild the Aircraft so as to keep all Aircraft
in as good a condition as presently exists or as when acquired by the Company
if any Aircraft are hereafter acquired (ordinary wear and tear excepted), and
as required to meet the air-worthiness standards of the Federal Aviation
Administration and the Department of Transportation (to the extent such
standards are applicable to the Aircraft) or the standards observed by the
Company with respect to Property of similar type, whichever is higher.  The
Company shall comply with all applicable mandatory maintenance, service,
repair, and overhaul manuals issued by the respective manufacturers of the
Aircraft.  The Company shall comply with all Laws of Tribunals having
jurisdiction over the Company or the Aircraft, including all applicable
requirements of the Federal Aviation Administration and the Department of
Transportation as to operation, maintenance, or use of the Aircraft.  In the
event that any such Law requires alteration of any Aircraft, the Company shall
conform thereto or obtain conformance therewith at no expense to the Agents or
the Banks and will maintain such Aircraft in proper operating condition under
such Laws; provided, however, that the Company may, in good faith, contest the
validity or application of any such Law in any reasonable manner which does not
materially adversely affect the Rights of the Agents or the Banks.

         Section 5.5         Maintenance of Books and Records.  The Company
shall, and shall cause each of its Subsidiaries to, maintain proper books of
record and account in which full, true, and correct entries in accordance with
GAAP consistently applied (except for any change with which the Company's
independent auditors concur) will be made of all dealings and transactions in
relation to their business and activities.

         Section 5.6         Inspection.  At reasonable times and upon
reasonable notice, the Company shall permit, and shall cause each of its
Material Subsidiaries to permit, any employees and other representatives of the
Administrative Agent or any Bank to visit and inspect any Properties, to
examine all books of account, records, reports, and other papers, to make
copies and extracts therefrom (subject to any confidentiality agreements,
copyright restrictions, and similar limitations), and to discuss the Company's
and Material Subsidiaries' affairs, finances, Properties, condition (financial
or otherwise) and accounts with the Company's and Material Subsidiaries'
officers, employees and independent certified public accountants, at such times
and as often as may be reasonably requested; provided, however, that (a) any
such inspection which includes Aircraft shall be a visual, walk-around
inspection and may not include opening any panels, bays or the like of any
Aircraft, (b) no exercise of any inspection rights provided for in this Section
5.6 shall interfere with the normal operation or maintenance of the Aircraft
by, or the business of, the Company, and (c) the Administrative Agent and each
Bank shall cause their respective employees and representatives to hold in
strict confidence all information acquired pursuant to such Agent's or Bank's
Rights under this Section 5.6, except for necessary disclosure to participants
in the Loans or Commitments, disclosure in connection with disputes relating to
the Loan Papers, or disclosure compelled by judicial or administrative process
or by other requirements of Law.

         Section 5.7         Insurance.  The Company shall maintain insurance
with such insurers, in such amounts (including by way of self-insurance and
deductibles), in such forms and covering such risks as may be then customary in
the domestic airlines industry.  Without in any way limiting the foregoing, the
Company shall maintain such insurance on the Aircraft, including "all-risk"
hull insurance and aviation liability insurance.

         Section 5.8         Appraisals.  On each Appraisal Delivery Date, the
Company shall submit an Appraisal of the Pool Assets to the Administrative
Agent as of the date which is 30 days prior to such Appraisal Delivery Date;
provided, however, that if such Appraisal is to be delivered on such Appraisal
Delivery Date as a consequence of clause (b) of the definition thereof, the
Appraisal to be delivered on such date shall only be in respect of the assets
to be removed from and/or added to the Pool Assets.

         Section 5.12        Restrictions on Sale-Leaseback Transactions; Pool
Assets.

                 (a)         At all times prior to the Asset Pool Date, neither
         the Company nor any of its consolidated Subsidiaries will engage in
         any Sale-Leaseback Transaction unless the amount of Sale-Leaseback
         Debt resulting from such transaction, plus the aggregate of all other
         Sale-Leaseback Debt then existing, does not at the time exceed 10% of
         Consolidated Net Tangible Assets; provided, however, if a
         Sale-Leaseback Transaction would result in Sale-Leaseback Debt
         exceeding such 10% limitation, then such Sale-Leaseback Transaction
         shall be permitted if such excess amount of the Sale-Leaseback Debt
         (i) were treated as Debt secured by a Lien, and (ii) would not,





                                      -54-
   60
         together with all other Debt of the Company and its Subsidiaries
         existing at the time and secured by Liens not excepted pursuant to
         Section 5.13(a), exceed the limitation imposed by Section 5.13(b).

                 (b)         At all times on or after the Asset Pool Date, the
         Company (i) will ensure that the Appraised Value of the Pool Assets
         shall satisfy the Collateral Coverage Test (based upon the most recent
         Appraisal delivered to the Administrative Agent and the Banks pursuant
         to the provisions of Section 5.8), and (ii) will not convey, sell,
         lease, transfer or otherwise dispose of, whether voluntarily or
         involuntarily (it being understood that loss of property due to theft,
         destruction, confiscation, prohibition on use or similar event shall
         constitute a disposal for purposes of this covenant), or remove or
         substitute, any Pool Asset (or any engine included in the Pool Assets
         unless such engine is replaced by another working engine or engines of
         comparable value, assuming half-time condition) or agree to do any of
         the foregoing at any future time, except that:

                             (1)          so long as no Event of Default
                 exists, the Company may replace a Pool Asset with another
                 asset of the Company (and Schedule II shall be modified to
                 reflect such replacement), provided that (A) such replacement
                 shall be made on a dollar-for-dollar basis based upon (x) in
                 the case of the asset being removed from the Pool Assets, the
                 Appraised Value of such Pool Asset (as determined by the most
                 recently delivered Appraisal with respect to such Pool Asset)
                 and (y) in the case of the asset being added to the Pool
                 Assets, the Appraised Value of such asset (as determined by an
                 Appraisal performed at the time of such replacement), and (B)
                 prior to effecting the replacement, the Company shall have
                 delivered a certificate of the Company signed by its duly
                 authorized officer to the Administrative Agent certifying
                 compliance with this Section 5.12(b) and attaching to such
                 certificate the Appraisal required by Section 5.8;

                             (2)          so long as no Event of Default exists
                 or would result therefrom, the Company may remove an asset
                 from the Pool Assets (and Schedule II shall be modified to
                 reflect such removal), provided that (A) after giving effect
                 to such removal, the Appraised Value of the





                                      -55-
   61
                 remaining Pool Assets (as determined by an Appraisal of all
                 Pool Assets performed at the time of such removal) shall
                 satisfy the Collateral Coverage Test, and (B) prior to
                 effecting the removal, the Company shall have delivered a
                 certificate of the Company signed by its duly authorized
                 officer to the Administrative Agent certifying that, and
                 providing calculations demonstrating that, after giving effect
                 to such removal, the Appraised Value of the Pool Assets shall
                 satisfy the Collateral Coverage Test, and otherwise certifying
                 compliance with this Section 5.12(b) and attaching to such
                 certificate Appraisals of all Pool Assets obtained in
                 connection with such removal; and

                             (3)          in the event (x) that an Appraisal
                 furnished pursuant to Section 5.8 discloses that the
                 Collateral Coverage Test is not satisfied or (y) the
                 Collateral Coverage Test is not satisfied following an
                 involuntary disposal of any Pool Asset (or any engine included
                 in the Pool Assets unless such engine is replaced by another
                 working engine or engines of comparable value, assuming
                 half-time condition) (whether by loss of property due to
                 theft, destruction, confiscation, prohibition on use, any
                 similar event or otherwise), based upon the most recent
                 Appraisal of the Pool Assets (from which the appraised values
                 of the Pool Assets which are the subject of the involuntary
                 disposition shall be subtracted) furnished pursuant to Section
                 5.8, the Company shall within 60 days after the date of such
                 Appraisal or involuntary disposal, as the case may be,
                 designate additional assets as Pool Assets to the extent that,
                 after giving effect to such designation the Appraised Value of
                 the Pool Assets, based on the most recently delivered
                 Appraisal with respect to assets already constituting Pool
                 Assets and based on an Appraisal performed at the time of such
                 addition with respect to assets being added to Pool Assets,
                 shall satisfy the Collateral Coverage Test (and Schedule II
                 shall be modified to reflect such addition), provided that (A)
                 at the time of such addition, the Administrative Agent and the
                 Banks shall have received a certificate of the Company signed
                 by its duly authorized officer certifying that the conditions
                 set forth in this Section 5.12(b) shall have been satisfied
                 after giving effect to such addition and attaching thereto
                 such Appraisal, and (B) the asset being added shall constitute
                 Stage 3 Equipment.

         Company will not, nor will it permit any Material Subsidiary to,
         issue, assume or guarantee any Debt directly or indirectly secured or
         collateralized by any Lien of or upon any Property of the Company or
         any Material Subsidiary (including without limitation shares of
         capital stock or indebtedness issued by any Material Subsidiary),
         whether such Property is owned at the date of this Agreement or
         hereafter acquired, without making effective provision whereby the
         Obligation (together with, if the Company shall so determine, any
         other Debt issued, assumed or guaranteed by the Company or any
         Material Subsidiary ranking equally with the Obligation and then
         existing or thereafter created) shall be secured by such Lien equally
         and ratably with (or, at the option of the Company, prior to) such
         Debt, so long as such Debt shall be so secured or collateralized;
         provided that the foregoing shall not apply to, nor prevent the
         creation or existence of, any of the following:

                             (1)          Liens of or upon any Property owned

                 the later of the acquisition, completion of construction or

                 (b)         Notwithstanding the provisions of subsection (a)
         of this Section 5.13, the Company or any Material Subsidiary may,
         without equally and ratably securing the Obligation, issue, assume or
         guarantee any Debt secured by a Lien not excepted by clauses (1)
         through (13) of such subsection (a), if the aggregate amount of such
         Debt, together with all other Debt of the Company and its Material
         Subsidiaries existing at such time and secured by Liens not so
         excepted, does not at the time exceed 10% of Consolidated Net Tangible
         Assets.

                 (c)         In the event the Company shall directly or
         indirectly secure or collateralize any Debt by any Lien of or upon any
         Aircraft, then the Company shall be deemed to have satisfied any
         resulting obligations under subsection (a) of this Section 5.13 to
         secure the Obligation equally and ratably with such Debt, if it shall
         secure or collateralize the Obligation with a Lien of the same type
         and rank of or upon other Aircraft, which other Aircraft shall have no
         less equivalent value relative to the aggregate principal amount of





                                      -59-
   65
         the Obligation than the Aircraft first referred to have in relation to
         the aggregate principal amount of such Debt.  All such Liens granted
         to or for the benefit of the Banks shall be granted and perfected
         pursuant to documentation reasonably satisfactory to the
         Administrative Agent and its counsel.

                 (d)         At all times on or after the Asset Pool Date, the
         Company will not, nor will it permit any Material Subsidiary to,
         create, assume or suffer to exist any Lien upon or with respect to the
         Pool Assets, or enter into any arrangement with any Person that would
         materially negatively impact the value of any Pool Asset realizable by
         any third party or assign any right to receive the proceeds from the
         sale, transfer or disposition of any of the Pool Assets, or file or
         suffer to exist the filing with respect to any of the Pool Assets of
         any financing statement naming the Company or any Material Subsidiary
         as debtor under the Uniform Commercial Code or any similar notice of
         Lien naming the Company or any Material Subsidiary as debtor under any
         similar recording or notice statute (including, without limitation,
         any filing under Title 49, United States Code, Section 44107), other
         than Permitted Liens affecting Pool Assets.

                 (e)         At all times on or after the Asset Pool Date, the
         Company will not enter into or suffer to exist, and will not permit
         any of its Material Subsidiaries to enter into or suffer to exist, any
         agreement prohibiting or conditioning the creation or assumption of
         any Lien upon any Pool Asset.

         Section 5.14        Mergers and Dissolutions.  Neither the Company nor
any Subsidiary will merge or consolidate with any Person other than any merger
or  consolidation whereby the Company (or, if the Company is not involved, the
Subsidiary) is the surviving corporation and no Default or Event of Default
exists or would result therefrom. Neither the Company nor any Subsidiary
(excluding any Subsidiary existing on the Execution Date to the extent that it
does not contribute more than two percent of the consolidated net income or own
more than two percent of the consolidated assets of the Company and its
Subsidiaries at the time of any such liquidation or dissolution) will
liquidate, wind up, or dissolve itself (or suffer any liquidation or
dissolution).

         Section 5.15        Assignment.  The Company will not assign or
transfer any of its Rights, duties, or obligations under any of the Loan
Papers.

                          EVENTS OF DEFAULT; REMEDIES

         Section 6.1         Events of Default.  Any one or more of the
following events shall be "Events of Default" hereunder (which shall include by
definition the expiration of any grace period with respect thereto), whether
the same shall occur and be continuing for any reason whatsoever (and whether
such occurrence shall be voluntary or involuntary or come about or be effected
by operation of Law or otherwise):

                 (a)         Payment of Obligation.  Failure to pay any
         installment of principal on any Loan when due whether at maturity, by
         declaration as authorized by this Agreement, or otherwise; or failure
         to pay, within 10 days after the due date thereof, any interest on any
         Loan; or failure to pay, within 10 days after the due date thereof, or
         if no due date therefor is herein specified within 10 days after
         written demand therefor is given to the Company by the Administrative
         Agent, any other amount payable by the Company hereunder or under any
         of the other Loan Papers.

                 (b)         Covenants.  Default shall be made in the
         observance or performance of any other of the covenants, conditions,
         and agreements on the part of the Company contained herein, or in any
         other Loan Papers and such default shall continue for a period of 30
         days after the Administrative Agent shall have given the Company
         notice thereof in writing.

                 (c)         Debtor Relief.  The Company or any Material
         Subsidiary shall file a voluntary petition in bankruptcy or a petition
         or answer seeking reorganization, arrangement, composition,
         liquidation, receivership, or similar relief under any Debtor Relief
         Law, or shall file a petition to take advantage of any Debtor Relief
         Law, or shall make an assignment for the benefit of creditors, or
         shall admit in writing its inability to pay its debts as they become
         due, or shall fail generally to pay its debts as they become due, or





                                      -61-
   67
         shall consent to the appointment of any receiver, trustee, custodian
         or liquidator of it or all or a substantial part of its Property; or a
         proceeding or action shall be instituted or commenced against the
         Company or any Material Subsidiary seeking an order for relief or a
         reorganization, arrangement, composition, liquidation, receivership,
         or similar relief under any Debtor Relief Law or seeking the
         appointment, without the consent of the Company or any Material
         Subsidiary, of any receiver, trustee, custodian or liquidator of it or
         all or a substantial part of the Property of the Company or any
         Material Subsidiary and such proceeding or action shall remain
         undismissed or unstayed for a period of 90 days; or an order, decree,
         or judgment for an involuntary petition adjudicating the Company or
         any Subsidiary insolvent shall be entered by any court of competent
         jurisdiction and shall remain undismissed or unstayed for a period of
         90 days.

                 (d)         Payment of Judgments.  The Company or any of its
         Material Subsidiaries fails to pay any judgment or order for the
         payment of money in excess of $25,000,000 rendered against it or any
         of its assets (exclusive of judgment amounts fully covered by
         insurance where the insurer has admitted liability in respect thereof)
         and either (i) any enforcement proceedings shall have been commenced
         by any creditor upon such judgment or order or (ii) the same shall not
         be discharged (or provisions shall not be made for such discharge), or
         a stay of execution thereof shall not be procured, within 30 days from
         the date of entry thereof and the Company or the relevant Material
         Subsidiary shall not, within said period of 30 days, or such longer
         period during which execution of the same shall have been stayed,
         appeal therefrom and cause the execution thereof to be stayed during
         such appeal.

                 (e)         Default on Other Debt or Security.  The Company or
         any Material Subsidiary shall (i) fail to pay any principal of or
         interest on any Debt (other than the Obligation) the principal or face
         amount of which exceeds $25,000,000 when due (or, where permitted,
         within any applicable grace period), whether by scheduled maturity,
         required prepayment, acceleration, demand or otherwise and such
         default continues unremedied for five Business Days after such due
         date or applicable grace period, or (ii) fail to perform or observe
         any other provision (other than a provision that is substantially
         identical to a provision in this Agreement)





                                      -62-
   68
         contained in any agreement securing or relating to such Debt (or any
         other breach or default under such Debt agreement occurs) if the
         effect of such failure to perform or observe such other provisions (or
         breach or default) is to cause such Debt to become due prior to its
         stated maturity; provided, however, that if any such failure, breach
         or default shall be waived or cured (as evidenced by a writing from
         such holder or trustee) then, to the extent of such waiver or cure,
         the Event of Default hereunder by reason of such failure, breach or
         default shall be deemed likewise to have been thereupon waived or
         cured.

                 (f)         ERISA.  Any "Reportable Event" as such term is
         defined in ERISA under any Plan, or the appointment by an appropriate
         Tribunal of a trustee to administer any Plan, or the termination of
         any Plan within the meaning of Title IV of ERISA, and any of the
         foregoing results in a material liability to the Pension Benefit
         Guaranty Corporation; or any material accumulated funding deficiency
         within the meaning of ERISA exists under any Plan.

                 (g)         Misrepresentation.  Any representation or warranty
         made by the Company is untrue in any material respect, or any
         certificate, schedule, statement, report, notice or writing (excluding
         any Appraisal, for which the Company makes no representation)
         furnished by the Company to the Agents or to the Banks, or any of
         them, is untrue in any material respect on the date as of which the
         facts set forth are stated or certified, shall remain material at the
         time of discovery and shall, if curable, remain incorrect in any
         material respect after 30 days after written notice thereof to the
         Company (any failure to include within any such schedule, statement,
         report, notice, or writing information which failure would cause the
         material included to be misleading shall be as much an untruth as a
         false statement contained therein).

         Section 6.2         Remedies Upon Default.  If an Event of Default
specified in Section 6.1(c) occurs, the Commitments of the Banks shall
thereupon automatically terminate and the aggregate unpaid principal balance of
and accrued interest on the Obligation shall thereupon become due and payable
concurrently therewith, without any action by the Administrative Agent or any
Bank and without diligence, presentment, demand, protest, notice of protest or
intent to accelerate, or notice of any other kind, all of which are





                                      -63-
   69
hereby expressly waived.  Except as set forth in the preceding sentence, should
any Event of Default occur and be continuing, the Administrative Agent may, and
if requested by the Majority Banks, shall, do any one or more of the following:

                 (a)         Acceleration.  Declare (by written notice to the
         Company) the entire unpaid balance of the Obligation, or any part
         thereof, immediately due and payable, whereupon it shall be due and
         payable, without diligence, presentment, demand, protest, notice of
         protest or intent to accelerate, or other notice of any kind (except
         any notice or demand specified in this Agreement), all of which are
         hereby expressly waived.

                 (b)         Termination.  Terminate the Commitments by written
         notice to the Company.

                 (c)         Judgment.  Reduce any claim to judgment.

                 (d)         Rights.  Exercise any and all legal and equitable
         Rights available to it.

         Section 6.3         Remedies in General.  If any Event of Default
shall occur and be continuing, the Administrative Agent may immediately proceed
to protect and enforce all or any Rights with respect thereto contained in this
Agreement or any other Loan Papers or may enforce any other legal or equitable
Rights.  Any Right may be exercised from time to time, independently or
concurrently, and as often as shall be deemed expedient.  No waiver of any
Event of Default shall extend to any subsequent Event of Default.


                                 ARTICLE VII

                                  THE AGENTS

         Section 7.1         Authorization and Action.  Each Bank hereby
irrevocably appoints and authorizes (a) TCB to act as its Administrative Agent
hereunder and under each of the other Loan Papers, (b) Chase to act as its
Auction Administration Agent hereunder and under each of the other Loan Papers,
(c) B of A to act as its Documentation Agent hereunder and under each of the
other Loan Papers, and (d) NationsBank to act as Syndication Agent hereunder.
TCB consents to such appointment and agrees to perform





                                      -64-
   70
the duties of the Administrative Agent hereunder and under the other Loan
Papers.  Chase consents to such appointment and agrees to perform the duties of
the Auction Administration Agent hereunder and under the other Loan Papers.  B
of A consents to such appointment and agrees to perform the duties of the
Documentation Agent hereunder and under the other Loan Papers.  NationsBank
consents to such appointment and agrees, in consultation with the Company and
the other Agents, to select a syndicate of Banks to participate in the
Commitments.  Each Bank authorizes and directs the Administrative Agent, the
Auction Administration Agent and the Documentation Agent to act on its behalf
and to exercise such powers under this Agreement as are specifically delegated
to or required of such Agent by the terms hereto, together with such powers as
are reasonably incidental thereto.  As to any matters not expressly provided
for by this Agreement or the other Loan Papers (including, without limitation,
enforcement or collection of the Loans or Notes), the Administrative Agent, the
Auction Administration Agent and the Documentation 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 Loans or Notes; provided,
however, that no Agent shall be required to take any action which exposes such
Agent to personal liability or which is contrary to this Agreement or
applicable Law.

         Section 7.2         Agents' Reliance, Etc.  None of the Agents and
none of their respective Affiliates, 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 Loan Papers (i) with the consent or at the request of
the Majority Banks (or the Majority Committed Banks or all the Banks, if
required) or (ii) in the absence of its or their own gross negligence or
willful misconduct (it being the express intention of the parties that the
Agents and their respective directors, officers, agents, and employees shall
have no liability for actions and omissions under this Section 7.2 resulting
from their ordinary contributory negligence).  Without limitation of the
generality of the foregoing, each Agent (i) may treat the payee of each Loan or
Note as the holder thereof until such Agent receives written notice of the
assignment or transfer thereof signed by such payee and in form satisfactory to
such Agent; (ii) may consult with legal counsel (including counsel for the
Company), independent public





                                      -65-
   71
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; (iii) makes no warranty or
representation to any Bank and shall not be responsible to any Bank for any
statements, warranties, or representations made by or on behalf of the Company
in or in connection with any Loan Paper; (iv) except as otherwise expressly
provided herein, 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
Loan Paper or to inspect the property (including the books and records) of the
Company or any of its Subsidiaries; (v) shall not be responsible to any Bank
for the due execution, legality, validity, enforceability, genuineness,
sufficiency, or value of any Loan Paper or any other instrument or document
furnished pursuant hereto or thereto; and (vi) shall incur no liability under
or in respect of any Loan Paper by acting upon any notice, consent,
certificate, or other instrument or writing (which may be by telecopier)
reasonably believed by it to be genuine and signed or sent by the proper party
or parties.

         Section 7.3         Rights of Agents as Banks.  With respect to their
Commitments, the Loans, if any, made by them and the Notes, if any, issued to
them, each Bank that is an Agent (including any Agent that hereafter becomes a
holder of a Loan or Note) and its Affiliates shall have the same rights and
powers under this Agreement or any other Loan Paper as any other Bank and may
exercise the same as though it were not an Agent; and the term "Bank" or
"Banks" shall, unless otherwise expressly indicated, include each Bank that is
an Agent (including any Agent that hereafter becomes a holder of a Loan or
Note), in its individual capacity.  Each Bank that is an Agent (including any
Agent that hereafter becomes a holder of a Loan or Note) 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 Company, any of the
Subsidiaries and any Person who may do business with or own securities of the
Company or of the Subsidiaries, all as if such Bank were not an Agent, and
without any duty to account therefor to the Banks.

         Section 7.4         Bank Credit Decision.  Each Bank acknowledges and
agrees that it has, independently and without reliance upon any of the Agents
or any other Bank and based on the Current Financials and such other documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter





                                      -66-
   72
into this Agreement.  Each Bank also acknowledges and agrees that it will,
independently and without reliance upon any of the Agents or any other Bank and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement.

         SECTION 7.5         AGENTS' INDEMNITY.  NONE OF THE AGENTS SHALL BE
REQUIRED TO TAKE ANY ACTION HEREUNDER OR TO PROSECUTE OR DEFEND ANY SUIT IN
RESPECT OF THIS AGREEMENT OR THE LOANS OR NOTES UNLESS INDEMNIFIED TO SUCH
AGENT'S SATISFACTION BY THE BANKS AGAINST LOSS, COST, LIABILITY, AND EXPENSE.
IF ANY INDEMNITY FURNISHED TO SUCH AGENT SHALL BECOME IMPAIRED, IT MAY CALL FOR
ADDITIONAL INDEMNITY AND CEASE TO DO THE ACTS INDEMNIFIED AGAINST UNTIL SUCH
ADDITIONAL INDEMNITY IS GIVEN.  IN ADDITION, THE BANKS AGREE TO INDEMNIFY EACH
AGENT OTHER THAN THE SYNDICATION AGENT (TO THE EXTENT NOT REIMBURSED BY THE
COMPANY), RATABLY ACCORDING TO THE RESPECTIVE PRINCIPAL AMOUNTS OF THE
COMMITTED LOANS THEN HELD BY EACH OF THEM (OR IF NO COMMITTED LOANS ARE AT THE
TIME OUTSTANDING, RATABLY ACCORDING TO EITHER (I) THE RESPECTIVE AMOUNTS OF
THEIR COMMITMENTS, OR (II) IF THE COMMITMENTS HAVE TERMINATED, THE RESPECTIVE
AMOUNTS OF THE COMMITMENTS IMMEDIATELY PRIOR TO SUCH TERMINATION), FROM AND
AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, 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
SUCH AGENT IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY
ACTION TAKEN OR OMITTED BY SUCH AGENT UNDER THIS AGREEMENT OR THE OTHER LOAN
PAPERS (INCLUDING, WITHOUT LIMITATION, ANY ACTION TAKEN OR OMITTED UNDER
ARTICLE II OF THIS AGREEMENT); PROVIDED 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 SUCH AGENT'S
FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  EACH BANK AGREES, HOWEVER, THAT
IT EXPRESSLY INTENDS, UNDER THIS SECTION 7.5, TO INDEMNIFY EACH AGENT RATABLY
AS AFORESAID FOR ALL SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, AND DISBURSEMENTS ARISING OUT OF OR
RESULTING FROM SUCH AGENT'S ORDINARY OR CONTRIBUTORY NEGLIGENCE.  WITHOUT
LIMITATION OF THE FOREGOING, EACH BANK AGREES TO REIMBURSE EACH AGENT (OTHER
THAN THE SYNDICATION AGENT) PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE OF ANY
OUT-OF-POCKET EXPENSES (INCLUDING REASONABLE COUNSEL FEES) INCURRED BY SUCH
AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION, ADMINISTRATION, OR
ENFORCEMENT OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER,
THIS





                                      -67-
   73
AGREEMENT AND THE OTHER LOAN PAPERS TO THE EXTENT THAT SUCH AGENT IS NOT
REIMBURSED FOR SUCH EXPENSES BY THE COMPANY.  THE PROVISIONS OF THIS SECTION
7.5 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT AND/OR THE PAYMENT OR
ASSIGNMENT OF ANY OF THE LOANS OR NOTES.

         Section 7.6         Successor Administrative Agent.  The
Administrative Agent may resign at any time by giving written notice thereof to
the Banks, the Auction Administration Agent, and the Company and may be removed
as Administrative Agent under this Agreement and the other Loan Papers at any
time with or without cause by the Majority Banks.  Upon any such resignation or
removal, the Majority Committed Banks or, after termination of the Commitments,
the Majority Banks shall have the right, with the consent of the Company
(provided that the Company's consent shall not be required during the
continuance of a Default or an Event of Default), to appoint a successor
Administrative Agent.  If no successor Administrative Agent shall have been so
appointed and shall have accepted such appointment within 30 calendar days
after the retiring Administrative Agent's giving notice of resignation or the
Majority Banks' removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Banks, with the consent of the
Company (provided that the Company's consent shall not be required during the
continuance of a Default or Event of Default), appoint a successor
Administrative 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 $500,000,000.  Upon the acceptance of any
appointment as Administrative Agent hereunder and under the other Loan Papers
by a successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all rights, powers, privileges and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations under this Agreement
and the other Loan Papers.  After any retiring Administrative Agent's
resignation or removal as the Administrative Agent hereunder and under the
other Loan Papers, the provisions of this Article VII shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was the
Administrative Agent under this Agreement and the other Loan Papers.

         Section 7.7         Successor Auction Administration Agent.  The
Auction Administration Agent may resign at any time by giving written notice
thereof to the Banks, the Administrative Agent, and the Company and may be
removed as Auction Administration Agent





                                      -68-
   74
under this Agreement and the other Loan Papers at any time with or without
cause by the Majority Banks.  Upon any such resignation or removal, the
Majority Committed Banks or, after termination of the Commitments, the Majority
Banks shall have the right, with the consent of the Company (provided that the
Company's consent shall not be required during the continuance of a Default or
an Event of Default), to appoint a successor Auction Administration Agent.  If
no successor Auction Administration Agent shall have been so appointed and
shall have accepted such appointment within 30 calendar days after the retiring
Auction Administration Agent's giving notice of resignation or the Majority
Banks' removal of the retiring Auction Administration Agent, then the retiring
Auction Administration Agent may, on behalf of the Banks, appoint a successor
Auction Administration Agent, with the consent of the Company (provided that
the Company's consent shall not be required during the continuance of a Default
or Event of Default), 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 $500,000,000.  Upon the acceptance of any
appointment as Auction Administration Agent hereunder and under the other Loan
Papers by a successor Auction Administration Agent, such successor Auction
Administration Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges, and duties of the retiring Auction Administration
Agent, and the retiring Auction Administration Agent shall be discharged from
its duties and obligations under this Agreement and the other Loan Papers.
After any retiring Auction Administration Agent's resignation or removal as the
Auction Administration Agent hereunder and under the other Loan Papers, the
provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was the Auction Administration
Agent under this Agreement and the other Loan Papers.

         Section 7.8         Successor Documentation Agent.  The Documentation
Agent may resign at any time by giving written notice thereof to the Banks, the
Administrative Agent, the Auction Administration Agent, and the Company and may
be removed as Documentation Agent under this Agreement and the other Loan
Papers at any time with or without cause by the Majority Banks.  Upon any such
resignation or removal, the Majority Committed Banks or, after termination of

Agent.  If no successor Documentation Agent shall have been so appointed and
shall have accepted such appointment within 30 calendar days after the retiring
Documentation Agent's giving notice of resignation or the Majority Banks'
removal of the retiring Documentation Agent, then the retiring Documentation
Agent may, on behalf of the Banks, appoint a successor Documentation Agent,
with the consent of the Company (provided that the Company's consent shall not
be required during the continuance of a Default or an Event of Default), 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 $500,000,000.  Upon the acceptance of any appointment as Documentation
Agent hereunder and under the other Loan Papers by a successor Documentation
Agent, such successor Documentation Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges, and duties of the retiring
Documentation Agent, and the retiring Documentation Agent shall be discharged
from its duties and obligations under this Agreement and the other Loan Papers. 
After any retiring Documentation Agent's resignation or removal as the
Documentation Agent hereunder and under the other Loan Papers, the provisions of
this Article VII shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was the Documentation Agent under this Agreement and
the other Loan Papers.

         Section 7.9         Notice of Default.  The Administrative Agent shall
not be deemed to have knowledge or notice of the occurrence of any Default or
Event of Default hereunder unless the Administrative Agent shall have received
notice from a Bank or the Company referring to this Agreement, describing such
Default or Event of Default and stating that such notice is a "notice of
default."  If the Administrative Agent receives such a notice, the
Administrative Agent shall give notice thereof to the Banks and the Auction
Administration Agent; provided, however, if such notice is received from a
Bank, the Administrative Agent also shall give notice thereof to the Company.
The Administrative Agent shall be entitled to take action or refrain from
taking action with respect to such Default or Event of Default as provided in
Section 7.1 and Section 7.2.

                                 MISCELLANEOUS

         Section 8.1         Amendments, Etc.  No amendment or waiver of any
provision of this Agreement or any other Loan Paper, nor consent to any
departure by the Company herefrom or therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Majority Committed Banks,
or after termination of the Commitments, the Majority Banks (or the
Administrative Agent with the consent of the Majority Committed Banks, or after
termination of the Commitments, the Majority Banks) in all cases, and then, in
any case, such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no amendment, waiver, or consent shall, unless in writing and signed by all the
Banks (or the Administrative Agent with the consent of all the Banks), do any
of the following:  (a) waive any of the conditions specified in Section 3.1,
3.2, or 3.3 (if and to the extent that the Borrowing which is the subject of
such waiver would involve an increase in the aggregate outstanding amount of
Loans over the aggregate amount of Loans outstanding immediately prior to such
Borrowing), (b) reduce or increase the amount or alter the terms of the
Commitments of any Banks or subject any Banks to any additional obligations,
(c) reduce the principal of, or rate or amount of interest applicable to, any
Loan other than as provided in this Agreement, or any fees hereunder, (d)
postpone any date fixed for any payment of principal of, or interest on, the
Loans or any fees hereunder, (e) change this Section 8.1, or (f) change the
percentage of the Commitments or of the aggregate unpaid principal amount of
the Loans, or the number of Banks, which shall be required for the Banks or any
of them to take any action hereunder; and provided, further, that no amendment,
waiver, or consent shall, unless in writing and signed by the Administrative
Agent in addition to the Banks required above to take such action, affect the
rights or duties of the Administrative Agent under this Agreement or any other
Loan Paper; and provided, further, that no amendment, waiver, or consent shall,
unless in writing and signed by the Auction Administration Agent in addition to
the Banks required to take such action, affect the rights or duties of the
Auction Administration Agent pursuant to this Agreement or any other Loan
Paper; and provided, further, that no amendment, waiver, or consent shall,
unless in writing and signed by the Documentation Agent in addition to the
Banks required to take such action, affect the rights or duties of the
Documentation Agent pursuant to this Agreement or any other Loan Paper.

of any Loan or Note giving consent or notice or making any request of the
Company provided for hereunder, shall notify each Bank, the Administrative
Agent, and the Auction Administration Agent thereof.  In the event that the
holder of any Loan or Note (including any Bank) shall transfer such Loan or
Note, it shall promptly so advise the Administrative Agent and the Auction
Administration Agent which shall be entitled to assume conclusively that no
transfer of any Loan or Note has been made by any holder (including any Bank)
unless and until such Agent receives written notice to the contrary.  Notices,

         hereto), or five days after being mailed to the address as set forth
         herein (or such other address designated by such party in a written
         notice to the other parties hereto) respectively, or when delivered to
         such address; provided, however, Communications to any Agent pursuant
         to Article II or Article VII shall not be effective until received by
         such Agent.

         Section 8.3         No Waiver; Remedies.  No failure on the part of
any Bank or any Agent to exercise, and no delay in exercising, any Right
hereunder or under any other Loan Paper shall operate as a waiver thereof; nor
shall any single or partial exercise of any such Right, or any abandonment or
discontinuance of any steps to enforce such Right, preclude any other or
further exercise thereof or the exercise of any other Right.  No notice to or
demand on the Company in any case shall entitle the Company to any other or
further notice or demand in similar or other circumstances.  The Rights herein
provided are cumulative and not exclusive of any Rights provided by Law.

         Section 8.4         Costs, Expenses and Taxes.  The Company agrees to
pay or reimburse the Agents for paying: (i) all reasonable costs and expenses
of the Agents in connection with (A) the preparation, execution, delivery, and
administration of this Agreement and the other Loan Papers, including, without
limitation, the reasonable fees and out-of-pocket expenses of counsel for the
Agents with respect thereto and with respect to advising the Agents as to their
respective Rights and responsibilities under this Agreement and the other Loan
Papers, and (B) any amendment, modification, supplement, or waiver of any of
the terms of this Agreement, and (ii) all reasonable costs and expenses of the
Banks and the Agents (including reasonable counsel's fees, and including
reasonable allocated in-house counsel fees for any Bank or any Agent) in
connection with the enforcement of this Agreement and the other Loan Papers.
In addition, the Company shall pay any and all Taxes payable or determined to
be payable in connection with the execution and delivery of this Agreement and
the other Loan Papers, and agrees to save the Agents and each Bank harmless
from and against any and all liabilities with respect to or resulting from any
delay in paying or omitting to pay such Taxes, if any, which may be payable or
determined to be payable in connection with the





                                      -73-
   79
execution and delivery of this Agreement or any other Loan Paper.  The
obligations of the Company under this Section 8.4 shall survive the termination
of this Agreement and/or repayment of the Loans.

         SECTION 8.5         INDEMNITY.  THE COMPANY AGREES TO INDEMNIFY AND
HOLD HARMLESS THE AGENTS AND THE BANKS AND EACH OF THEIR RESPECTIVE AFFILIATES,
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS AND REPRESENTATIVES AGAINST
ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, CLAIMS, COSTS, DEFICIENCIES, EXPENSES, AND DISBURSEMENTS OF
ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED
AGAINST ANY AGENT, ANY BANK, OR ANY OF THEIR RESPECTIVE AFFILIATES, OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR OTHER REPRESENTATIVES IN ANY WAY
RELATING TO OR ARISING OUT OF THE LOAN PAPERS, ANY TRANSACTION RELATED HERETO,
OR ANY ACT, OMISSION, OR TRANSACTION OF THE COMPANY, ITS SUBSIDIARIES, AND
AFFILIATES, OR ANY OF THEIR EMPLOYEES, OFFICERS, DIRECTORS OR OTHER
REPRESENTATIVES, TO THE EXTENT THAT ANY OF THE SAME RESULTS, DIRECTLY OR
INDIRECTLY, FROM ANY CLAIMS MADE OR ACTIONS, SUITS, OR PROCEEDINGS COMMENCED BY
OR ON BEHALF OF ANY PERSON OTHER THAN AN AGENT OR A BANK.  THE OBLIGATION OF
THE COMPANY UNDER THIS SECTION SHALL CONTINUE FOR A PERIOD OF ONE YEAR AFTER
PAYMENT OF THE OBLIGATION AND TERMINATION OF ANY OR ALL LOAN PAPERS, AND SHALL
NOT BE RELIEVED BY ANY CLAIM OR ALLEGATION OF NEGLIGENCE BY ANY AGENT OR ANY
BANK; PROVIDED, HOWEVER, THAT ALTHOUGH EACH INDEMNIFIED PARTY SHALL HAVE THE
RIGHT TO BE INDEMNIFIED FROM ITS OWN ORDINARY NEGLIGENCE, NO INDEMNIFIED PARTY
SHALL HAVE THE RIGHT TO BE INDEMNIFIED HEREUNDER FOR ITS OWN FRAUD, GROSS
NEGLIGENCE, OR WILLFUL MISCONDUCT.

         Section 8.6         Right of Setoff.  If any Event of Default shall
have occurred and be continuing, each Bank is hereby authorized at any time
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 Company against any and all obligations of
the Company now or hereafter existing under this Agreement and the Loans held
by such Bank, irrespective of whether or not such Bank shall have made any
demand under this Agreement or any Note and although such obligations may be
unmatured.  Each Bank agrees promptly to notify the Company and the
Administrative Agent after any such setoff and application made by such Bank,
but the failure to give such notice shall not affect the validity of such
setoff





                                      -74-
   80
and application.  The Rights of each Bank under this Section 8.6 are in
addition to the Rights and remedies (including, without limitation, other
Rights of setoff) which such Bank may have.

         SECTION 8.7         GOVERNING LAW; VENUE; SERVICE OF process.

                 (a)         THIS AGREEMENT AND ALL OTHER LOAN PAPERS SHALL BE
         DEEMED TO BE CONTRACTS AND AGREEMENTS EXECUTED BY THE COMPANY, THE
         AGENTS, AND THE BANKS UNDER THE LAWS OF THE STATE OF TEXAS AND OF THE
         UNITED STATES AND FOR ALL PURPOSES SHALL BE CONSTRUED IN ACCORDANCE
         WITH, AND GOVERNED BY, THE LAWS OF SAID STATE AND OF THE UNITED
         STATES.  Without limitation of the foregoing, nothing in this
         Agreement or in any Note shall be deemed to constitute a waiver of any
         Rights which any Bank may have under applicable federal legislation
         relating to the amount of interest which such Bank may contract for,
         take, receive, or charge in respect of any Loans, including any Right
         to take, receive, reserve, and charge interest at the rate allowed by
         the Law of the states where such Bank is located.  The provisions of
         Chapter 15 of Article 5069 of the Texas Revised Civil Statutes do not
         apply to this Agreement or any Note issued hereunder.

                 (b)         TO THE EXTENT PERMITTED BY APPLICABLE LAW, ANY
         ACTION OR PROCEEDING AGAINST THE COMPANY UNDER OR IN CONNECTION WITH
         ANY OF THE LOAN PAPERS MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT IN
         DALLAS COUNTY, TEXAS.  TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE
         COMPANY HEREBY IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE
         JURISDICTION OF SUCH COURTS, AND (B) WAIVES ANY OBJECTION IT MAY NOW
         OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING
         BROUGHT IN ANY SUCH COURT OR THAT ANY SUCH COURT IS AN INCONVENIENT
         FORUM.  THE COMPANY AGREES THAT SERVICE OF PROCESS UPON IT MAY BE MADE
         BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, AT ITS
         ADDRESS SPECIFIED OR DETERMINED IN ACCORDANCE WITH THE PROVISIONS OF
         SECTION 8.2.  NOTHING HEREIN OR IN ANY OF THE OTHER LOAN PAPERS SHALL
         AFFECT THE RIGHT OF ANY AGENT OR ANY BANK TO SERVE PROCESS IN ANY
         OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF ANY AGENT OR
         ANY BANK TO BRING ANY ACTION OR PROCEEDING AGAINST THE COMPANY OR WITH
         RESPECT TO ANY OF ITS PROPERTY IN COURTS IN OTHER JURISDICTIONS.  ANY
         ACTION OR PROCEEDING BY THE COMPANY AGAINST ANY AGENT OR ANY BANK
         SHALL BE BROUGHT ONLY IN A COURT LOCATED IN DALLAS COUNTY, TEXAS.

   81
         Section 8.8         Usury Not Intended.  The Company and the Banks
intend to strictly comply with all applicable Laws, including Applicable Laws.
Accordingly, the provisions of this Section 8.8 shall govern and control over
every other provision of this Agreement and any Note, whenever executed, which
conflicts with this Section 8.8, even if such provision declares that it
controls (unless such provision expressly identifies and refers to this Section
8.8 and specifically states that it will control over this Section 8.8).  As
used in this Section 8.8, the term "interest" includes the aggregate of all
charges which constitute interest under Applicable Laws, provided that, to the
maximum extent permitted by Applicable Laws, (a) any non-principal payment
shall be characterized as an expense or fee or something other than
compensation for the use, forbearance, or detention of money and not as
interest, and (b) all interest at any time contracted for, reserved, charged,
or received shall be amortized, prorated, allocated, and spread, in equal or
unequal parts throughout the entire contemplated term of the Borrowings so that
interest for the entire term does not exceed the maximum rate permitted by
Applicable Laws.  In no event shall the Company or any other Person be
obligated to pay, or any Bank have any right or privilege to contract for,
reserve, receive, retain, or charge (a) any interest in excess of the maximum
amount of nonusurious interest permitted under Applicable Laws, or (b) total
interest in excess of the amount which such Bank could lawfully have contracted
for, reserved, received, retained, or charged had the interest been calculated
for the full term of the Borrowings at the Highest Lawful Rate.  On each day,
if any, that the interest rate (the "Stated Rate") called for under this
Agreement or under any Note or other related document exceeds the Highest
Lawful Rate, the rate at which interest shall accrue shall automatically be
fixed by operation of this sentence at the Highest Lawful Rate for that day,
and shall remain fixed at the Highest Lawful Rate (or at any time no Highest
Lawful Rate shall exist, at the Agreed Maximum Rate) for each day thereafter
until the total amount of interest accrued equals the total amount of interest
which would have accrued if there were no such ceiling rate as is imposed by
this sentence.  Thereafter, interest shall accrue at the Stated Rate unless and
until the Stated Rate again exceeds the Highest Lawful Rate when the provisions
of the immediately preceding sentence shall again automatically operate to
limit the interest accrual rate.  The daily interest rates to be used in
calculating interest at the Highest Lawful Rate shall be determined by dividing
the applicable Highest Lawful Rate per annum by the number of days in the
calendar





                                      -76-
   82
year for which such calculation is being made.  None of the terms and
provisions contained in this Agreement, any Note, or any other Loan Paper which
directly or indirectly relate to interest shall ever be construed without
reference to this Section 8.8 or construed to create a contract to pay for the
use, forbearance, or detention of money at an interest rate in excess of the
Highest Lawful Rate.  If the term of any Loan is shortened by reason of
acceleration of maturity as a result of any Event of Default or other cause, or
by reason of any required or permitted prepayment, and if for that (or any
other) reason any Bank at any time (including but not limited to the stated
maturity of any Borrowing) is owed or receives (and/or has received) interest
in excess of interest calculated at the Highest Lawful Rate, then and in any
such event all of any such excess interest shall be cancelled automatically as
of the date of such acceleration, prepayment, or other event which produces the
excess, and, if such excess interest has been paid to a Bank, it shall be
credited pro tanto against the then-outstanding principal balance of the
Company's obligations to such Bank, effective as of the date or dates when the
event occurs which causes it to be excess interest, until such excess is
exhausted or all of such principal has been fully paid and satisfied, whichever
occurs first, and any remaining balance of such excess shall be promptly
refunded to its payor.

         Section 8.9         Survival of Representations and Warranties.  All
representations and warranties contained herein or made in writing by the
Company in connection herewith shall survive the execution and delivery of this
Agreement and the other Loan Papers, and no investigation by any Agent or any
Bank or any closing shall affect the representations and warranties or the
Right of any Agent or any Bank to rely upon them.

         Section 8.10        Binding Effect.  This Agreement shall become
effective when it shall have been executed by the Company, the Agents, and each
Bank and thereafter shall be binding upon and inure to the benefit of the
Company (subject to the provisions of Section 8.11), the Agents, each Bank and
their respective successors and assigns.

         Section 8.11        Successors and Assigns; Participations.

                 (a)         Whenever in this Agreement any of the parties
         hereto is referred to, such reference shall be deemed to include the
         successors and permitted assigns of such party; and all





                                      -77-
   83
         covenants, promises, agreements, representations and warranties by or
         on behalf of the Company, the Agents or the Banks that are contained
         in this Agreement shall bind and inure to the benefit of their
         respective successors and assigns.  The Company may not assign or
         transfer any its rights or obligations hereunder without the prior
         written consent of all of the Banks.

                 (b)         Each Bank may without the consent of the Company
         sell participations to one or more banks or other entities in all or a
         portion of its rights and obligations under this Agreement (including,
         without limitation, all or a portion of its Commitment and the Loans
         owing to it and any Note or Notes held by it); provided, however, that
         (i) such Bank's obligations under this Agreement shall remain
         unchanged, (ii) such Bank shall remain solely responsible to the other
         parties hereto for the performance of such obligations, (iii) such
         Bank shall remain the holder of its Loans and Notes (if any) for all
         purposes of this Agreement, (iv) the participating banks or other
         entities shall be entitled to the cost protection provisions contained
         in Article IIand Section 8.4, but only to the extent that such
         protection would have been available to such Bank, calculated as if no
         such participations had been sold, and the indemnity protection
         provisions contained in Section 8.5, (v) the Company, the Agents, 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 (vi) such Bank shall not sell a participation that
         conveys to the participant the right to vote or give or withhold
         consents under this Agreement or any other Loan Papers, other than the
         right to vote upon or consent to (y) amendments, modifications, or
         waivers with respect to any fees payable hereunder (including the
         dates fixed for the payment of any such fees) or the amount of
         principal or the rate of interest payable on, or the dates fixed for
         any payment of principal of or interest on, the Loans and (z) any
         extension of the Termination Date.

                 (c)         Each Bank may assign, with the prior written
         consent of the Company (which consent shall not be unreasonably
         withheld and shall not be required after the occurrence or during the
         continuance of a Default or Event of Default) and the Administrative
         Agent, to one or more Eligible Assignees, all or a portion of its
         interests, rights, and obligations





                                      -78-
   84
         under this Agreement (including, without limitation, all or a portion
         of its Commitment and the same portion of the Committed Loans at the
         time owing to it; provided, however, that (i) each Bank's Commitment
         (including Loans owing to it) shall not be less than $10,000,000,
         minus reductions pursuant to Section 2.6(a), (ii) each such assignment
         shall be of a constant, and not a varying, percentage of all the
         assigning Bank's rights and obligations under this Agreement (other
         than any Competitive Loans, any Competitive Notes and any right to
         make Competitive Loans), (iii) the assignee thereof shall deliver to
         the Company and the Administrative Agent any Internal Revenue Service
         forms required by Section 2.19, and (iv) the parties to each such
         assignment shall execute and deliver to the Administrative Agent, for
         its acceptance and recording in the Register (as defined below), an
         Assignment and Acceptance substantially in the form of Exhibit H
         hereto (an "Assignment and Acceptance"), together with a properly
         completed Administration Questionnaire, any Note or Notes subject to
         such assignment and a processing and recordation fee of $2,000 (or
         such lesser amount as shall be acceptable to the Administrative
         Agent); provided, however, no such fee shall be required in the case
         of any assignment requested by the Company pursuant to Article II of
         this Agreement.  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
         Business Days after the execution thereof (unless a shorter period
         shall be agreed to by the Company, the Administrative Agent, and the
         assignor Bank), (x) the Eligible Assignee thereunder shall be a party
         hereto and, to the extent provided in such Assignment and Acceptance,
         have the rights and obligations of a Bank hereunder and under the
         other Loan Papers and (y) the assignor Bank thereunder shall, to the
         extent provided in such Assignment and Acceptance, be released from
         its obligations under this Agreement and the other Loan Papers (and,
         in the case of an Assignment and Acceptance covering all of the

         on behalf of such Eligible Assignee and to exercise such powers under

                                      -80-
   86
         in the absence of manifest error, and the Company, the Agents, 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 Company, any Bank, the
         Administrative Agent, or the Auction Administration Agent at any
         reasonable time and from time to time upon reasonable prior notice.

                 (f)         Upon its receipt of an Assignment and Acceptance
         executed by an assigning Bank and an Eligible Assignee together with
         any Note or Notes subject to such assignment and the written consent

         Exhibit H hereto, (i) accept such Assignment and Acceptance, (ii)
         record the information contained therein in the Register, and (iii)
         give prompt notice thereof to the Banks, the Administrative Agent, the
         Auction Administration Agent, and the Company.  Within five Business
         Days after receipt of such notice, the Company, at its own expense,
         shall execute and deliver to the Administrative Agent in exchange for
         the surrendered Note or Notes, if any, (x) a new Committed Note or
         Committed Notes to the order of such Eligible Assignee in an amount
         equal to its portion of the Commitment assumed by it pursuant to such
         Assignment and Acceptance, (y) if the assigning Bank has retained its
         Competitive Note, a new Competitive Note to the order of the Eligible
         Assignee, and (z) if the assigning Bank has retained any Commitment
         hereunder, new Committed Notes to the order of the assigning Bank in
         an amount equal to the Commitment retained by it hereunder.  Such new
         Committed Notes shall be in an aggregate principal amount equal to the
         aggregate principal amount of such surrendered Committed Notes.  Such
         new Committed Notes and Competitive Notes shall be dated the effective
         date of such Assignment and Acceptance and shall otherwise be in
         substantially the form of Exhibit D-1 or D-2 as applicable, hereto.
         Cancelled Notes shall be returned to the Company.

                 (g)         Notwithstanding any other provision herein, any
         Bank may, in connection with any assignment or participation or
         proposed assignment or participation pursuant to this Section 8.11,
         disclose to the assignee or participant or proposed assignee or
         participant any information relating to the Company and its
         Subsidiaries furnished to such Bank by or





                                      -81-
   87
         on behalf of the Company; provided, that prior to any such disclosure,
         each such assignee or participant or proposed assignee or participant
         shall agree for the benefit of the Company to preserve the
         confidentiality of any confidential information relating to the
         Company received from such Bank.

                 (h)         Notwithstanding any other provision set forth in
         this Agreement, any Bank may at any time create a security interest in
         all or any portion of its Rights under this Agreement (including,
         without limitation, the Loans owing to it and any Notes held by it) in
         favor of any Federal Reserve Bank in accordance with Regulation A of
         the Board.

         Section 8.12         Independence of Covenants.  All covenants
contained in this Agreement shall be given independent effect so that if a
particular action or condition is not permitted by any such covenants, the fact
that such action or condition would be permitted by an exception to, or
otherwise be within the limitations of, another covenant shall not avoid the
occurrence of a Default or Event of Default if such action is taken or
condition exists.
 
         Section 8.13        Severability.  Should any clause, sentence,
paragraph, or Section of this Agreement be judicially declared to be invalid,
unenforceable, or void, such decision will not have the effect of invalidating
or voiding the remainder of this Agreement, and the parties hereto agree that
the part or parts of this Agreement so held to be invalid, unenforceable, or
void will be deemed to have been stricken herefrom and the remainder will have
the same force and effectiveness as if such part or parts had never been
included herein.

         Section 8.14        Entire Agreement.     THIS AGREEMENT, THE FEE
LETTERS BETWEEN THE COMPANY AND THE RESPECTIVE AGENTS, AND THE OTHER LOAN
PAPERS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES HERETO AND SUPERSEDE
ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS,
WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF, AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.  Without in any way limiting the foregoing, this Agreement supersedes
that certain Competitive Advance and Revolving Credit Facility Agreement dated
as of December 14, 1990, as amended, among the Company and the Banks and Agents
named therein, and the commitments of such Banks thereunder are hereby
terminated.
