	NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

	SIX MONTHS ENDED OCTOBER 31, 1996 AND 1995

	(UNAUDITED)


A.	These financial statements, except for the April 30, 1996 condensed
        consolidated balance sheet, have been prepared without audit as
        permitted by the rules and regulations of the Securities and Exchange
        Commission.  Certain information and footnote disclosures normally
        included in the financial statements have been condensed or omitted
        pursuant to such rules and regulations; however, the Company believes
        that this information is fairly presented.  These condensed
        consolidated financial statements should be read in conjunction
        with the financial statements contained in the Company's Annual
        Report on Form 10-K for the year ended April 30, 1996 and the
        accompanying notes and Management's Discussion and Analysis of
        Financial Condition and Results of Operations.

B.	In the opinion of management, the accompanying unaudited condensed
        consolidated financial statements contain all adjustments, consisting
        of only normal, recurring adjustments, necessary to fairly present
        the financial results for the interim periods presented.

C.	The Company's financial results, particularly as it relates to its
        domestic oil and gas operations, are influenced by seasonal
        fluctuations. During the winter, there are more days of adverse
        weather conditions and fewer hours of daylight than the other months
        of the year.  Consequently, flight hours are generally lower during
        the Company's third fiscal quarter than at other times of the year.
        This produces a seasonal aspect to the Company's business and
        typically results in reduced revenues from operations during those
        months.  Therefore, the results of operations for interim periods are
        not necessarily indicative of the operating results that may be
        expected for the full fiscal year.

D.	Primary earnings per share are computed based on the weighted average
        number of shares and dilutive equivalent shares of common stock
        (stock options) outstanding during each year using the treasury stock
        method.

E.	Certain reclassifications have been made to the prior year's
        financial statements in order to conform with the classifications
        adopted for reporting in fiscal 1997.

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

The Company is engaged in providing helicopter transportation and related
services.  The predominant portion of its revenue is derived from
transporting offshore oil and gas production and drilling workers on a
worldwide basis.  The Company also performs helicopter transportation
services for a variety of hospital and medical programs and aircraft
maintenance to outside parties.

RESULTS OF OPERATIONS

The following is a comparison of the second quarter and the first six months
of the fiscal year ending April 30, 1997 with the comparable period of the
prior fiscal year.

Second Quarter Fiscal 1997 to Fiscal 1996

Revenues

The Company generates revenues from both ongoing service contracts with
established customers and non-contract flights referred to as Specials.
Domestic Oil and Gas contracts are generally on a month to month basis and
consist of a fixed fee plus an hourly charge for actual flight time.
Specials are customer flights, primarily domestic oil and gas, provided on an
as needed basis that are not provided pursuant to ongoing contracts and which
generally carry higher rates.

International and aeromedical contracts also provide for fixed and hourly
charges, but are generally for longer terms.  These contracts impose early
cancellation fees to encourage customers to fulfill the contract term and
cover the Company's additional upfront costs in the event of early
termination.

The following table summarizes and compares the Company's revenues by certain
market segments for the quarters ended October 31, 1996 and 1995:

Domestic Oil and Gas

   Domestic Oil and Gas revenues increased $3 million, or 9%, to $ 37.6
million for the quarter.The Company attributes this increase to better
economic conditions in the Gulf of Mexico.  As of October 31, 1996 the
Company had thirty more aircraft under contract than last year at
October 31, 1995.  Domestic flight hours increased 10% to 48,072 hours from
43,724 hours, as compared to the quarter ended October 31, 1995.
 
Aeromedical Services

   Aeromedical revenues increased to $ 7.5 million, or 14%, from $ 6.6
million.  This increase is due primarily to the addition of two new programs
and the utilization of five additional aircraft bringing the total
Aeromedical contracts and aircraft to fourteen and thirty-eight, respectively.
EMS flight hours increased 12% to 3,739 hours from 3,344 hours.

International and Technical Services

   International Oil and Gas revenues increased $ 2.6 million, or 68%, to
$ 6.4 million.International flight hours increased 60% to 7,951 hours from
4,984 hours.  The increase in revenue and flight hours is due primarily to
the addition of two new contracts which utilize thirteen dedicated aircraft.

   Technical Services and other revenues increased $ 0.8 million from 
$ 2.9 million to $ 3.7 million.

Direct Expenses

   Direct expenses increased $ 5.6 million, or 13%, to $ 47.1 million
primarily as a result of increased activity levels. Direct expenses did not
increase proportionately with the increase in revenues which improved the
Company's operating margin to 15% compared to 13% in the prior years
comparable quarter. Direct expenses that did not show a proportional increase
were primarily spare parts usage, depreciation expense, and helicopter rent.

   Human Resources costs, including employee benefit costs, increased $ 2.7
million, or 16%.This increase is due primarily to the hiring of additional
personnel which were needed to support higher levels of flight activity.

   Helicopter expenses increased $ 0.9 million, or 5%, to $ 20.4 million.
Fuel expense, spare parts usage, and depreciation expense increased $ 0.8
million, $ 0.2 million, and $ 0.2 million, respectively.  These increases
were primarily the result of increased fuel costs, increased flight activity,
and the purchase of additional aircraft, respectively.  The average fuel cost
per gallon increased by $ 0.18 which accounted for $ 0.5 million of the fuel
cost increase.  These costs were offset by a decrease in insurance costs and
helicopter rent of $ 0.3 million and $ 0.2 million, respectively.

  Other expenses and Technical Services cost of goods sold increased $ 1.1
million and $0.7 million, respectively.
                                       

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses increased by $ 0.5 million
to $ 3.4 million for the quarter.  This increase was primarily a result of
consultant fees related to information system upgrades.

Domestic Oil and Gas

   For the first six months Domestic Oil and Gas revenues increased 9%,
or $ 6 million, to $ 73 million due primarily to increased activity in the
Gulf of Mexico.  The Company attributes the increase to better economic
conditions in the Gulf of Mexico; a result of rising crude oil and natural
gas prices and increased drilling activity.  These factors produced a 10%
increase in Domestic Oil and Gas flight hours.  The company maintained its
market share at 52% for the current and prior year period.

Aeromedical Services

  Aeromedical revenues increased to $ 15.1 million, or 17%, from $ 12.9
million.  This increase is due primarily to the addition of two new programs
and the utilization of five additional aircraft bringing the total
Aeromedical contracts and aircraft to fourteen and thirty-eight,
respectively.  EMS flight hours increased 18% to 7,691 hours from 6,518
hours.


International and Technical Services

   International Oil and Gas revenues increased substantially to $ 11.4
million, or 39%, due primarily to the addition of two new contracts which
utilize thirteen aircraft.  Flight hours increased 42% to 14,650 hours.

   Technical Services and other revenues decreased slightly to $ 5.8 million
from $ 6.1 million, or 5%.

Direct Expenses

   Direct expenses increased $ 6.9 million, or 8%, to $ 89.5 million
primarily as a result of increased flight activity.  Direct expenses did not
increase proportionately with the increase in revenues which improved the
Company's operating margin to 15% compared to 12% in the prior years
comparable period.  Direct expenses that did not show a proportional
increase were primarily spare parts usage and helicopter rent.

   Human resources costs increased $ 3.3 million from $ 33.2 million to
$ 36.5 million.  This increase is due primarily to the hiring of additional
personnel which were needed to support higher levels of flight activity.

   Helicopter expenses increased $ 1.2 million, or 3%, to $ 39.5 million from
$ 38.3 million.  Fuel expense, depreciation expense, and spare parts usage
increased $ 1.2 million, $ 0.4 million, and $ 0.1 million, respectively.
Fuel costs increased due to a $ 0.15 average cost per gallon increase and an
increase in flight activity.  Depreciation expense and spare parts usage
increased due to the purchase of additional aircraft and higher maintenance
requirements associated with increased flight activity, respectively.
These costs were partially offset by a decrease in insurance expense of $ 0.6
million and a decrease in helicopter rent of $ 0.2 million.

   Other expenses and Technical Services cost of goods sold increased $ 1.9
million and $ 0.2 million, respectively.

Selling, General, and Administrative Expenses

   Selling, general, and administrative expenses increased $ 1.2 million
from $ 5.4 million to $ 6.6 million.  The increase was primarily a result of
consultant fees related to information systems upgrades.

LIQUIDITY AND CAPITAL RESOURCES

   The following is comparison of the first six months of the fiscal year
ending April 30, 1997 with the period ending April 30, 1996.

   The Company's cash position as of October 31, 1996 was $ 3 million
compared to $ 1.9 million at April 30, 1996, the Company's fiscal year end.
Working capital increased $ 9.1 million from $ 26.5 million at fiscal year
end to $ 35.6 million.  The increase was primarily related to an increase in
accounts receivable of $ 7.1 million and an increase in inventory of $ 3.8
million, offset by an increase in accounts payable of $ 1.2 million.

   Total long-term debt increased $ 26.5 million to $ 55 million.  On
August 13, 1996 the Company and its principal lending group ratified a loan
agreement that amended and restated its original loan agreement dated January
1, 1986.  The new agreement increased the Company's credit capacity to $ 65
million from $ 55 million.  In addition, the new agreement lowers the
Company's effective interest rate on its outstanding debt under this
facility.  The annual projected interest expense reduction for the fiscal
year ended April 30, 1997, using the total debt outstanding under this
facility at October 31, 1996, is $0.1 million.  The Company's current debt
obligation totals $ 8.8 million, due in equal quarterly installments, which
the Company intends to pay with cash flow from operations.  At
November 29, 1996, the Company had $ 10 million credit capacity available
under its revolving credit facility.  The Company is in compliance with all
provisions of its loan agreement.


   Cash generated from operating activities and financing activities was
$ 1.9 million and $ 26 million, respectively.  The Company utilized its cash
flow from operating activities and financing activities to fund $ 26.8
million in investing activities.  Investing activities primarily included
the purchase of twenty-two aircraft for $ 17.7 million, and $ 5.2 million
in aircraft capital improvements.  The Company paid dividends totaling
$ 0.5 million or $ 0.10 per share.

   The Company continues to review selected domestic bases for possible
fuel contamination resulting from routine flight operations, and to date the
company has identified known or suspected fuel contamination at five of its
bases.  Although the full extent of contamination has not been determined,
based on this preliminary information, a provision of $ 1.7 million was made
for remediation costs through the fiscal year ended April 30, 1996 and an
additional $ 0.8 million provision was made in the first six months of fiscal
1997.  The company will make additional provisions to the extent necessary as
reliable estimates of these costs become available.

   In the first quarter of fiscal year 1996, the Company acquired a 49%
interest in Irish Helicopters Limited (IHL) based in Dublin Ireland.  IHL
was recently notified that its principal service contract will not be renewed
and will therefore terminate on December 31, 1996.  As a result, IHL is
reviewing a number of alternatives including the possibility that it will
not continue as a going concern.  Based on the final determination of IHL's
plans, PHI will evaluate and adjust, as necessary its investment which
currently aggregates $3.7 million.

compliance with all the terms and provisions of this Agreement with the
same effect as if the same were a portion of the original Aircraft

registration, recordation or filing documents and any other appropriate
security documentation as the Agent or any Bank through the Agent may
request for the purpose of describing said Aviation Unit (including all

apparatus, appurtenances and accessories) in reasonable detail, and
expressly and specifically subjecting the same to the Security Interest;
(d) delivering or causing to be delivered to the Agent and each Bank an
opinion of counsel (dated the date of the filing for recordation in the

full compliance with all provisions of this Agreement with respect to the
same.

account such factors as the Agent may deem appropriate.  The Prime Rate is
not necessarily the lowest or best rate actually charged to any customer,
and such rate may not correspond with future increases or decreases in
interest rates charged by other lenders or market rates in general.  The
Agent and any of the Banks may make various business or other loans at
rates of interest having no relationship to the Prime Rate.  Without
notice to the Company or any other person, the Prime Rate shall change
automatically from time to time, as determined by the Agent, subject

of such conversion or continuation) and ending 1, 2, 3, 4, 6, 9 or 12
months thereafter, as the Company may specify in the Request for Borrowing

Periods are subject to the following:

     such Rate Period shall end on the immediately preceding Business
     Day;

          (2)  any Rate Period that would otherwise extend beyond the

2.   THE LOANS.

     2.01 Loans.

          (a)  Upon the terms and conditions set forth in this
Agreement, each Bank agrees to renew, modify and extend the loans made by
it to the Company pursuant to the Prior Amended and Restated Loan
Agreement and to convert such loans to principal outstanding under a
revolving credit facility that will be used for general corporate purposes
and for funding the Company's purchase of additional Aviation Units and
that will convert into a term facility on the Conversion Date (the
"Loans"), and to make additional Loans to the Company as part of
Borrowings hereunder on any one or more Business Days on or after the
Effective Date to but not including the Conversion Date, up to an
aggregate principal amount not exceeding at any one time outstanding its
Commitment, subject to the provisions of Section 8.16.  After giving
effect to the foregoing, each Bank's Loans shall be evidenced by a single
Note, payable to the order of such Bank in installments and bearing
interest payable (except as otherwise provided in Article 3) on each
Interest Payment Date and on the date when such Loan is paid in full at
the rate or rates set forth in Section 2.03.  Within the limits set forth
above and subject to the terms and conditions of this Agreement, the
Company may prior to, but not on or after the Conversion Date, borrow
under this Subsection 2.01(a), repay or prepay the Loans pursuant to
Article 3 and reborrow under this Subsection 2.01(a).  On and after the
Conversion Date, the Commitments of the Banks are no longer revolving in
nature and amounts repaid or prepaid may not be reborrowed.  The
conversion of the indebtedness due to each Bank under the loans made to
the Company pursuant to the Prior Amended and Restated Loan Agreement into
the Loans under the terms of this Agreement, shall not effect a novation
of, but shall be, to the fullest extent applicable, in modification,
renewal, extension, rearrangement and replacement of the term loans made
by the Banks to the Company pursuant to the Prior Amended and Restated
Loan Agreement.

          (b)  The aggregate principal amount of the Loans shall be
payable in quarterly installments each in an amount equal to the lesser of
(i) the greater of (x) $1,500,000 and (y) 3.75% of the aggregate principal
amount of the Loans outstanding as of the immediately preceding October 31
and (ii) the aggregate principal amount of the Loans outstanding as of
such date, which quarterly installments shall be payable on the last day
of each January, April, July and October of each year, commencing October
31, 1996 and ending on the first such date (after the Conversion Date) on
which the aggregate unpaid principal amount of the Loans shall be paid in
full by reason of quarterly installments paid as aforesaid and any
prepayments made pursuant to Article 3 or otherwise (but in any event no
later than October 31, 2002) (the "Termination Date").

          (c)  Each Bank shall post on a schedule attached to its Note
or in records relating to its Note (i) the date and principal amount of
each Loan, (ii) the rate of interest each such Loan will bear, and
(iii) each payment of principal and interest thereon; provided, however,
that neither the failure to make any such postings nor any inaccuracy
therein shall affect the Company's obligations under any Note or this
Agreement.  The information set forth on such schedule shall be rebuttably
presumptive evidence of the matters described in the immediately preceding
sentence.

     2.02 Borrowing Procedure.

          (a)  The Prime Rate Loans and the LIBOR Loans shall be made
upon at least three (3) full Business Days' prior notice from the Company
to the Agent and each Bank (a "Notice of Borrowing").  Each such Notice of
Borrowing shall specify (i) the Borrowing Date, (ii) the total amount of
the proposed Loans (which shall be for not less than $1,000,000 and in an
integral multiple of $250,000), and (iii) whether such Loans are to be
Prime Rate Loans or LIBOR Loans, and if such Loans are to be LIBOR Loans,
the Rate Period applicable thereto.

          (b)  In connection with each Borrowing to be used to fund the
Company's purchase of additional Aviation Units, the Company shall (i)
deliver, prior to the Borrowing Date set forth in the Notice of Borrowing
related to such Borrowing, to the Agent, with a copy to each Bank,
invoices, receipts, or other evidence of purchase (such evidence to be
within seven (7) days prior to such Borrowing Date) showing an aggregate
value thereof that is greater than or equal to the amount of the Borrowing
referred to in such Notice of Borrowing and (ii), pursuant to, and within
the time periods specified by, Section 9.05(a), subject such helicopters
or other Aviation Units to the Security Interest and execute and deliver
to the Agent Security Documents, satisfactory to the Agent, to subject
such helicopters or other Aviation Units to the Security Interest, and
(iii) comply with each of the requirements set forth in clause (a) of the
second paragraph of Section 7.11 in relation to such helicopters or other
Aviation Units.

          (c)  The failure of any Bank to make the Loan to be made by
it as part of any Borrowing shall not relieve any other Bank of its
obligation, if any, hereunder to make its Loan on the date of such
Borrowing, but no Bank shall be responsible for the failure of any other
Bank to make the Loan to be made by such other Bank on the date of any
Borrowing.

          (d)  Not later than 11:00 a.m. (Dallas time) on the Borrowing
Date for each Borrowing, each Bank shall make its Ratable Share of such
Borrowing available at the Office of the Agent in immediately available
funds.  On each Borrowing Date, provided each Bank shall have made its
Ratable Share of the applicable Borrowing available to the Agent as
required by the immediately preceding sentence, the Agent shall pay the
proceeds of such Borrowing in immediately available funds to or upon the
order of the Company no later than 2:00 p.m. (Dallas time).

          (e)  Unless the Agent shall have received notice from a Bank
prior to the date of any Borrowing that such Bank will not make available
to the Agent such Bank's Ratable Share of such Borrowing, the Agent may
assume that such Bank has made such Ratable Share available to the Agent
on the date of such Borrowing in accordance with Subsection 2.02(c), and
the Agent may, in reliance upon such assumption, make available to the
Company on such date a corresponding amount.  If and to the extent such
Bank shall not have so made such Ratable Share available to the Agent,
such Bank, upon demand, and the Company, within three (3) Business Days
after demand, severally agree to repay to the Agent such corresponding
amount together with interest thereon, for each day from the date such
amount is made available to the Company until the date such amount is
repaid to the Agent, at the federal funds rate.  If such Bank shall repay
to the Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan as part of such Borrowing for purposes of this
Agreement.

     2.03 Rates of Interest.  The Loans shall bear interest on the
unpaid principal amount thereof from time to time outstanding at a rate or
rates per annum as follows:

          (a)  The Loans shall bear interest prior to maturity (by
acceleration or otherwise) at (i) for the Loans maintained as Prime Rate
Loans at the lesser of (A) the Applicable Prime Rate and (B) the Highest
Lawful Rate in effect from time to time and (ii) for the Loans maintained
as LIBOR Loans, at the lesser of (A) the LIBOR Rate applicable during such
Rate Period, and (B) the Highest Lawful Rate in effect from time to time
during such Rate Period.  Interest on the Prime Rate Loans shall be due
and payable quarterly on (each a "Prime Rate Interest Payment Date") the
last day of each January, April, July and October commencing on the last
day of October, 1996, and on each such date thereafter until the date
(after the Conversion Date) when all principal amounts outstanding under
the Notes shall be paid in full and until the obligation of each Bank to
make Loans shall be terminated.  Interest on each LIBOR Loan shall be due
and payable on each Prime Rate Interest Payment Date, and, if not a Prime
Rate Interest Payment Date, the last day of each Rate Period for such
LIBOR Loan (each a "LIBOR Interest Payment Date" and, together with each
Prime Rate Interest Payment Date, an "Interest Payment Date").

          (b)  Overdue amounts of principal and interest on the Notes
shall bear interest payable on demand at a rate per annum (based on a year
of 365 or 366 days and actual days lapsed) equal to the lesser of the
Highest Lawful Rate or 3% per annum above the Prime Rate, but in no event
to exceed the maximum rate allowed by La. R.S. S 9:3509.1 if and to the
extent applicable.

          (c)  (i) If the Applicable Prime Rate, the LIBOR Rate or the
Commitment Fee should become subject to adjustment in accordance with the
definition of the term Applicable Prime Rate, LIBOR Margin or Commitment
Fee, respectively, in Section 1.01, such adjustment shall:

          (A)  be made upon receipt by the Banks of the quarterly
          financial statements required to be delivered pursuant to
          Section 7.01, 

          (B)  be effective as of the first day of the fiscal quarter
          of the Company following the fiscal quarter reported upon in
          such financial statements, and 

          (C)  remain effective for each day thereafter until the first
          day of the fiscal quarter of the Company following the failure
          to meet or the exceeding of the requirements of the applicable
          clause of the definition of the term Applicable Prime Rate,
          LIBOR Margin or Commitment Fee, as applicable, in
          Section 1.01.  

               (ii) In the event any such adjustment to the Applicable
     Prime Rate, the LIBOR Rate or the Commitment Fee, respectively,
     shall result in the amount of interest or fees paid to any Bank on
     a previous Interest Payment Date being more or less than the amount
     due on such Interest Payment Date calculated at the adjusted level,
     the amount of any overpayment or underpayment, as the case may be,
     to such Bank resulting therefrom shall be deducted from or added to,
     respectively, the amount of interest or fees due to such Bank on the
     next Interest Payment Date succeeding such adjustment to the
     Applicable Prime Rate, the LIBOR Rate or the Commitment Fee,
     respectively; provided, however that no deductions or additions
     shall occur after the Termination Date with respect to interest or
     fees paid on any Loan, or the Conversion Date with respect to any
     fees paid with respect to the unused portion of the Commitments, and
     any adjustment to the Applicable Prime Rate, the LIBOR Rate or the
     Commitment Fee, respectively, that would otherwise require such
     deduction or addition after such date shall be of no effect.  

               (iii)     All adjustments to the Applicable Prime Rate, the
     LIBOR Rate or the Commitment Fee, respectively, provided for in this
     Subsection 2.03(c) and in the definition of Applicable Prime Rate,
     LIBOR Margin and Commitment Fee, respectively, in Section 1.01 shall
     be adequately supported, in the sole but reasonable discretion of
     the Banks, by the quarterly financial statements required to be
     delivered from the Company to the Banks pursuant to Section 7.01.

     2.04 Increased Costs - Reserve Requirements, Etc.

          (a)  If any Bank determines that compliance with any law or
regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or
would affect the amount of capital required or expected to be maintained
by such Bank or any corporation controlling such Bank and that the amount
of such capital is increased by or based upon the existence of such Bank's
Loans or Commitment and other loans or commitments of this type then, upon
demand by such Bank (with a copy of such demand to the Agent), the Company
shall immediately pay to such Bank from time to time as specified by such
Bank, additional amounts sufficient to compensate such Bank or such
corporation in the light of such circumstances, to the extent that such
Bank reasonably determines such increase in capital to be allocable to the
existence of any of such Bank's Loans or Commitment hereunder.

          (b)  The Company shall pay immediately upon demand by the
Agent any applicable stamp and registration taxes, duties, official and
sealed paper taxes or similar charges due, or which under applicable law
could in the future become due, or which may in the future become due as
a result of any change in applicable law, the interpretation thereof, or
otherwise, in connection with any Borrowing or the Notes or this Agreement
or in connection with the enforcement hereof or thereof.

          (c)  A certificate of any Bank seeking direct payment,
compensation or reimbursement under this Section 2.04 and setting forth a
computation of the amount or amounts to be paid by the Company shall be
delivered to the Company and shall be conclusive in the absence of
manifest error.

     2.05 Recapture.  Notwithstanding anything in this Agreement to the
contrary, if the rate of interest applicable to any Borrowing or portion
thereof (the "Applicable Rate") would, but for the limitation of the rate
herein to the Highest Lawful Rate, for any period of time exceed the
Highest Lawful Rate, the rate of interest to accrue on such Borrowing or
portion thereof during such period shall be limited to the Highest Lawful
Rate, but such Borrowing shall bear interest thereafter at the Highest
Lawful Rate until the total amount of interest accrued thereon equals the
amount of interest which would have accrued thereon if the Applicable Rate
would have at all times been in effect during such period.

     2.06 Commitment Fees; Agent's Fees.

          (a)  The Company agrees to pay to the Agent for the account
of each Bank the Commitment Fee, from and including the Effective Date to
and including the Termination Date.  The Commitment Fee shall be due and
payable on each Prime Rate Interest Payment Date, and shall be computed
for the period commencing with the day on which the Commitment Fee was
last paid, as the case may be, to but not including the day the Commitment
Fee is due and payable.

          (b)  In addition to the Commitment Fees described above, the
Company agrees to pay to the Agent for the period from and including the
Effective Date to and including the date upon which all obligations of the
Company under this Agreement, the Notes and the Security Documents have
been paid in full and neither the Agent nor any Bank has any commitment
hereunder, an agent's fee for its services as Agent in an amount equal to
(a) $25,000 on the first day of May in each year in which this Agreement
shall be in effect as of such date, and (b) on the date on which all such
obligations are paid in full and neither the Agent nor any Bank has any
commitment hereunder, an amount equal to $25,000 times a fraction, the
numerator of which is the number of days that has elapsed from but not
including the date on which such Agent's fee was last paid to and
including the date on which such obligations are paid in full and neither
the Agent nor any Bank has any commitment hereunder, and the denominator
of which is 365.

     2.07 Payments, Notice of Certain Repayments, and Computations.

          (a)  All payments by the Company of principal, interest and
Commitment Fees hereunder and under the Notes shall be made in Dollars to
the Agent at the Office of the Agent for the account of each of the
respective Banks in immediately available funds not later than 11:00 a.m. 
(Dallas time) on the date when due.  The Company hereby authorizes each
Bank, if and to the extent payment is not made within three (3) days of
the date when due pursuant to any Note held by such Bank or the provisions
of this Agreement, to debit any account of the Company with such Bank in
an amount equal to the principal, interest, expenses, reimbursements,
compensation, Commitment Fees, and any other amount from time to time due
under any Note payable to such Bank or hereunder or under any Security
Document.  Any Bank which so debits an account of the Company shall give
the Company and the Agent prompt notice of such debit, the amount thereof
and the obligations of the Company to which the amount so debited was

rate applicable to the Loans in accordance with this Agreement, and the
Agent's determination thereof shall be conclusive in the absence of
clearly demonstrated error.

     2.08 Set-Off, Counterclaims and Taxes.  All payments of principal,
interest, expenses, reimbursements, compensation and any other amount from
time to time due hereunder or under the Notes shall be made by the Company
without set-off 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
taxing authority, excluding income and franchise taxes of the United
States and any political subdivision thereof.  If the making of such
payments is prohibited by law unless such a tax, levy, impost or other
charge is deducted or withheld therefrom, the Company shall pay to the
Agent, on the date of each such payment, such additional amounts as may be
necessary in order that the net amounts received by the Agent after such
deduction or withholding shall equal the amounts which would have been
received if such deduction or withholding were not required.  A
certificate of the Agent seeking payment of such additional amounts under
this Section 2.08 and setting forth a computation of the amount or amounts
to be paid to it by the Company shall be delivered to the Company and
shall be conclusive in the absence of manifest error.  The Company shall
confirm that all applicable taxes, if any, imposed on this Agreement or on
any transaction 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 Agent within 30 days after

of the Banks, provided that such termination and each such partial
reduction shall be irrevocable and that each such partial reduction shall
be in the aggregate amount of $1,000,000 or an integral multiple thereof,
and provided, further, that the Company shall not reduce the sum of the
Commitments at any time to an amount less than the aggregate unpaid
principal amount of the Notes and the Permitted Letter of Credit Amounts,

Commitments of the Banks shall be deemed reduced or terminated, as the
case may be, as provided in such notice.

purposes of the Company.

          (a)  With respect to the principal amount of the Loans
outstanding from time to time, subject to the terms and provisions of this
Agreement, the Company shall have the option, to (a) convert on any
Business Day all or any part of such outstanding principal amount
maintained as a Prime Rate Loan at such time to a LIBOR Loan; provided,
however, that each such LIBOR Loan shall be in a principal amount greater
than or equal to $1,000,000 or an integral multiple of $500,000 in excess
thereof, (b) convert all or any part of such outstanding principal amount
maintained as a LIBOR Loan to a Prime Rate Loan on the last day of the
Rate Period relating to such LIBOR Loan, or (c) effective as of the last
day of any Rate Period during which the outstanding principal amount of a
Loan is maintained as a LIBOR Loan, continue all or a portion of such
outstanding principal amount as a LIBOR Loan and the succeeding Rate
Period of each such continued LIBOR Loan shall commence on the last day of
the Rate Period then ended; provided, however, that each such continued
LIBOR Loan shall be in a principal amount greater than or equal to
$1,000,000 or an integral multiple of $500,000 in excess thereof. 
Notwithstanding anything set forth herein, none of the outstanding
principal amount of the Loans shall be converted to, or continued as, a
LIBOR Loan if (y) the last day of the Rate Period relating to such LIBOR
Loan does not occur on or before the Termination Date or (z) a Default or
an Event of Default has occurred and is continuing.

          (b)  In the event the Company shall elect to convert or
continue all or any part of the outstanding principal amount of a Loan as
provided in the immediately preceding Subsection 2.11(a), the Company
shall deliver a written notice to the Agent (each such notice, a "Notice
of Conversion or Continuation") (x) with respect to the conversion of all
or any part of a Loan to a LIBOR Loan or the continuation of any LIBOR
Loan, no later than 11:00 a.m., Dallas, Texas time three Business Days in
advance of the proposed conversion or continuation date, and (y) with
respect to the conversion of all or any part of a LIBOR Loan to a Prime
Rate Loan, no later than 11:00 a.m., Dallas, Texas time on the Business
Day immediately preceding the proposed conversion date, specifying in each
case (i) the amount of the outstanding principal amount of each Loan that
is to be converted or continued, (ii) the date of such proposed conversion
or continuation, which date shall be a Business Day, (iii) whether the
proposed conversion is of (A) Prime Rate Loan(s) to LIBOR Loan(s), or (B)
LIBOR Loan(s) to Prime Rate Loan(s), (iv) in the case of a conversion to,
or continuation of, a LIBOR Loan, the requested Rate Period, (v) the
aggregate principal amount of the Loans outstanding after giving effect to
such conversion or continuation, and (vi) that no Default or Event of
Default has occurred and is continuing.  Each Notice of Conversion or
Continuation shall be irrevocable and the Company shall be bound to
convert or continue in accordance therewith.

          (c)  If with respect to all or any part of the outstanding
principal amount of any LIBOR Loan the Company fails to timely submit a
Notice of Conversion or Continuation, such outstanding principal amount
shall, effective as of the last day of the Rate Period relating thereto,
automatically and without notice of any kind be converted to a Prime Rate
Loan. 

     2.12 Provisions Relating to LIBOR Loans.

          (a)  Notwithstanding anything set forth this Agreement, the
Banks shall not be obligated to convert all or any part of the outstanding
principal amount of any Loan maintained as a LIBOR Loan to a Prime Rate
Loan until the last day of the Rate Period relating to such LIBOR Loan.

          (b)  If the Company shall have requested a LIBOR Loan or
requested that all or any part of the outstanding principal amount of any
Loan be converted to, or continued as, a LIBOR Loan and the Agent in good
faith determines (which determination shall be conclusive) that
extraordinary circumstances make it impossible or impracticable to
ascertain the applicable LIBOR Rate for the applicable Rate Period, such
Loan or portion thereof shall instead be funded, converted into or
continued, as the case may be, as a Prime Rate Loan.

          (c)  Notwithstanding anything set forth in this Agreement, if
at any time the Agent in good faith determines (which determination shall
be final and conclusive) that the introduction of, or any change in, any
applicable law, rule, regulation or treaty or any change in the
interpretation, application or administration thereof by any governmental
or other regulatory authority charged with the interpretation, application
or administration thereof shall make it unlawful for any of the Banks to
maintain or fund any LIBOR Loan, the Agent shall give notice thereof to
the Company and effective as of the date of such notice, and
notwithstanding Subsection 2.12(a), the outstanding principal amount of
such LIBOR Loan shall be converted to a Prime Rate Loan.  Within five (5)
Business Days after any Bank's written notice and demand therefor, the
Company shall pay to such Bank such amount or amounts (to the extent that
such amount or amounts would not be usurious under applicable Law and to
the extent such amount or amounts have not been included in the
determination of the LIBOR Rate) as may be necessary to compensate such
Bank for any direct or indirect costs and losses incurred by it under, in
connection with or as a result of such conversion, but otherwise without
penalty.  If notice with respect to any LIBOR Loan has been given by the
Agent pursuant to the foregoing provisions of this Subsection 2.12(c)
then, unless and until the Agent notifies the Company that the
circumstances giving rise to such notice no longer apply, the Banks shall
have no obligation to make or convert all or any part of the outstanding
principal amount of any Loan into a LIBOR Loan.  Any claim by the Banks
for compensation under this Subsection 2.12(c) shall be accompanied by a
certificate setting forth the computation upon which such claim is based
and such certificate shall be conclusive and binding for all purposes
absent manifest error.

          (d)  In the event that any law, regulation, treaty or
directive or any change therein or in the interpretation, application or
administration thereof or compliance by any Bank with any request or
directive (whether or not having the force of law) from any central bank
or other governmental authority, agency or instrumentality, does or shall,
as a result of, or with respect to, any LIBOR Loan:

               (i)  subject such Bank to any tax, duty or other charge
          of any kind whatsoever with respect to this Agreement, any
          other Loan Document or all or any part of the outstanding
          principal amount of any Loan, or change the basis of taxation
          of payments to such Bank of principal, interest or any other
          amount payable hereunder or under any other Loan Document
          (except for changes in the rate of any tax presently imposed
          on such Bank);

               (ii) impose, modify or hold applicable any reserve,
          special deposit, compulsory loan or similar requirement
          against assets held by, or deposits or other liabilities in or
          for the account of, advances or loans by, or other credit
          extended by, or any other acquisition of funds by, any office
          of such Bank; or

               (iii)     impose on such Bank any other condition;

and the result of any of the foregoing is to increase the cost to such
Bank of making, renewing or maintaining advances or extensions of credit
to the Company or to reduce any amount receivable from the Company
thereunder then, in any such case (and to the extent not already included
in the calculation of the applicable LIBOR Rate), the Company shall
promptly pay to such Bank, within five (5) Business Days after such Bank's
written notice and demand therefor, any amounts necessary to compensate
such Bank for such additional cost or reduced amount receivable.  Any
claim by a Bank for compensation under this Subsection 2.12(d) shall be
accompanied by a certificate setting forth the computation upon which such
claim is based and such certificate shall be conclusive and binding for
all purposes absent manifest error.

          (e)  In the event any prepayment under Section 3.02 requires
the Company to prepay a LIBOR Loan, or any part thereof, prior to the last
day of the Rate Period relating thereto, within five (5) Business Days
after the Agent's demand therefor the Company shall pay to the Agent such
amount or amounts (to the extent that such amount or amounts would not be
usurious under applicable Law) as may be necessary to compensate the Banks
for any costs and losses incurred by it under, in connection with or as a
result of such prepayment.  Any claim by the Agent for compensation under
this Subsection 2.12(e) shall be accompanied by a certificate setting
forth the computation upon which such claim is based and such certificate
shall be conclusive and binding for all purposes absent manifest error.

          (f)  The Company may not prepay any LIBOR Loan before the
last day of the Rate Period relating thereto, except for payments required
under Section 3.02(b).

     2.13 Permitted Letters of Credit.  Subject to the terms and
conditions of this Agreement, the Company may request that the Issuing
Bank issue, from time to time during the period commencing on the
Effective Date, and ending on the Business Day immediately prior to the 
Conversion Date, for the account of the Company through such of the
Issuing Bank's branches as it and the Company may jointly agree, one or
more letters of credit in accordance with this Section 2.13 and subject to
the provisions of Section 8.16 (each such letter of credit issued in
accordance with this Section 2.13, being individually referred to as a
"Permitted Letter of Credit" and collectively referred to as the
"Permitted Letters of Credit").  Notwithstanding the foregoing, the
Issuing Bank shall not have any obligation to issue any Permitted Letter
of Credit at any time.

          The Company may request issuances of Permitted Letters of
Credit only if:

          (a)  the aggregate undrawn face amount of Permitted Letters
of Credit theretofore issued by the Issuing Bank, after giving effect to
all requested but unissued Letters of Credit, does not exceed any limit
imposed by law or regulation upon the Issuing Bank;

          (b)  immediately after giving effect to the issuance of such
Permitted Letter of Credit, the aggregate amount of Permitted Letter of
Credit Amounts would not exceed $5,000,000 and the amount available for
Loans under the Commitments would not be less than $0; 

          (c)  such Permitted Letter of Credit has an expiration date
on or before the Business Day immediately preceding the Conversion Date; 

          (d)  the Company shall have satisfied in full the conditions
precedent set forth in Section 6.02 as though such Permitted Letter of
Credit constituted a Loan in the face amount thereof;

          (e)  the Company shall have delivered to the Issuing Bank, at
such times and in such manner as the Issuing Bank may prescribe, a
Permitted Letter of Credit application, a Letter of Credit Reimbursement
Agreement, and such other documents and materials as may be required
pursuant to the terms thereof;

          (f)  the terms of the proposed Permitted Letter of Credit
shall not be inconsistent with any term or provision of this Agreement and
otherwise shall be reasonably satisfactory to the Issuing Bank; and

          (g)  as of the date of issuance of such Permitted Letter of
Credit, no order, judgment, or decree of any court, arbitrator, or
Governmental Authority shall purport by its terms to enjoin or restrain
the Issuing Bank from issuing such Permitted Letter of Credit, and no law,
rule, or regulation applicable to the Issuing Bank, and no request or
directive (whether or not having the force of law) from any Governmental
Authority having jurisdiction over the Issuing Bank, shall prohibit or
request that the Issuing Bank refrain from the issuance of letters of
credit generally or the issuance of such Permitted Letter of Credit.

     2.14 Issuance of Permitted Letters of Credit.

          (a)  The Company shall give the Issuing Bank written notice
in an Officers' Certificate of its request for the issuance of a Permitted
Letter of Credit no later than 10:00 a.m. three (3) Business Days prior to
the date such Permitted Letter of Credit is requested to be issued.  Such
notice shall be irrevocable and shall specify, with respect to such
requested Permitted Letter of Credit, the face amount, beneficiary,
effective date of issuance, expiry date (which effective date and expiry
date shall be a Business Day and, with respect to the expiry date, shall
be no later than the Business Day immediately preceding the Conversion
Date), and the currency in which, and the purpose for which, such
Permitted Letter of Credit is to be issued.  The Issuing Bank may issue
such Permitted Letter of Credit on the date requested by the Company,
unless (i) on or before the Business Day prior to such issuance date, the
Issuing Bank shall have received written notice from any Bank that the
conditions precedent to the Company's request for an issuance of a
Permitted Letter of Credit as set forth in Section 2.13 have not been met;
or (ii) on the requested issuance date, the officer of the Issuing Bank
executing such Permitted Letter of Credit has actual knowledge that such
conditions precedent to the Company's request for an issuance of a
Permitted Letter of Credit as set forth in Section 2.13 have not been met. 
If the Issuing Bank receives written notice, or such officer has actual
knowledge that the conditions precedent to the Company's request for an
issuance of a Permitted Letter of Credit have not been met, then the
Issuing Bank shall not issue any Permitted Letter of Credit until (a) such
notice is withdrawn; (b) the condition(s) described in such notice have
been waived in accordance with the provisions of this Agreement, or (c)
such officer shall have actual knowledge of the satisfaction of all
conditions precedent having been met.

          (b)  The Issuing Bank shall not extend or amend any Permitted
Letter of Credit unless the requirements of this Section 2.14 are met as
though a new Permitted Letter of Credit was being requested and issued.

     2.15 Reimbursement Obligations; Duties of Issuing Bank.

          (a)  Notwithstanding any provisions to the contrary in any
Letter of Credit Reimbursement Agreement:

               (i)  The Company shall reimburse the Issuing Bank for
          a drawing under a Permitted Letter of Credit issued by the
          Issuing Bank no later than the earlier of (A) the time
          specified in the related Letter of Credit Reimbursement
          Agreement; or (B) one (1) Business Day after the Issuing Bank
          has provided notice (which notice may be in writing or oral,
          including without limitation oral notice by telephone) of any
          payment of such drawing by the Issuing Bank; and

               (ii) the Company's Reimbursement Obligation with
          respect to a drawing under a Permitted Letter of Credit shall
          bear interest from the date of such drawing to the date paid
          in full at the Applicable Prime Rate.

          (b)   No action taken or omitted to be taken by the Issuing
Bank in connection with any Permitted Letter of Credit shall (i) result in
any liability on the part of the Issuing Bank to any other Bank, unless
the Issuing Bank's action or omission constitutes willful misconduct or
gross negligence; or (ii) relieve any Bank of any of its obligations to
the Issuing Bank hereunder, unless the Permitted Letter of Credit in
question was issued at a time during which a notice, described in Section
2.14, from such Bank to the Issuing Bank remained in effect.  Each Bank
agrees that, prior to making any payment to a beneficiary with respect to
a drawing under a Permitted Letter of Credit, the Issuing Bank shall be
responsible only to confirm that documents required by the terms of such
Permitted Letter of Credit to be delivered as a condition precedent to
such drawing have been delivered and that the same appear on their face to
conform with the requirements thereof.  Each Bank further agrees that the
Issuing Bank may assume that documents appearing on their face to be the
documents required to be delivered as a condition precedent to a drawing
do in fact comply.

     2.16 Participations.

          (a)  Immediately upon the issuance by the Issuing Bank of any
Permitted Letter of Credit in compliance with the provisions of Section
2.13, each Bank, other than the Issuing Bank, shall be deemed to have
irrevocably and unconditionally purchased and received from the Issuing
Bank, without recourse or warranty, an undivided interest and
participation to the extent of such Bank's Ratable Share in such Permitted
Letter of Credit, including, without limitation, all obligations of the
Company with respect thereto and any security therefor or guaranty
pertaining thereto.

          (b)  The Issuing Bank shall promptly notify each other Bank,
if the Company fails to reimburse the Issuing Bank for payments made by
the Issuing Bank in respect of drawings by a beneficiary under a Permitted
Letter of Credit.  Upon such Bank's receipt of such notice, such Bank
shall unconditionally pay to the Agent, for the account of the Issuing
Bank, an amount equal to such Bank's Ratable Share of the unreimbursed
payment made by the Issuing Bank under the Permitted Letter of Credit. 
Such payment shall be made by such Bank in the same currency in which the
applicable Permitted Letter of Credit was denominated and in same day
funds on the day such Bank receives notice from the Agent that such
payment is owing, if such notice is received by such Bank prior to 10:00
a.m. (Dallas, Texas time) on a Business Day; if such notice is not
received by such time, then such Bank shall remit its payment on the next
Business Day following the day such notice is received.  Any amount
payable by a Bank under this Subsection 2.16(b) which is not paid when due
pursuant to the terms hereof, shall be payable on demand, together with
interest thereon at the federal funds rate from the date such payment was
due until paid in full.  The failure of any Bank to make any payment owing
by it under this Subsection 2.16(b) shall neither relieve nor increase the
obligation of any other Bank to make any payment owing by it under this
Subsection 2.16(b).  The Agent shall promptly remit to the Issuing Bank
all amounts received by the Agent, for the account of the Issuing Bank,
from each other Bank pursuant to this Subsection 2.16(b).

          (c)  Whenever the Issuing Bank receives a payment with
respect to a Reimbursement Obligation (including any interest thereon) for
which the Issuing Bank has received payments from another Bank pursuant to
Subsection 2.16(b), the Issuing Bank shall promptly remit to each Bank
which has funded its participating interest therein, in the currency and
in the kind of funds so received, an amount equal to such Bank's Ratable
Share thereof.  Each such payment shall be made by the Issuing Bank on the
Business Day on which such person receives the funds paid to such person
pursuant to the preceding sentence, if received prior to 10:00 a.m.
(Dallas, Texas time) on such Business Day, and otherwise on the next
succeeding Business Day.

          (d)  The obligations of a Bank under Subsection 2.16(b) to
make payments to the Agent for the account of the Issuing Bank with
respect to a Permitted Letter of Credit shall be irrevocable, not subject
to any qualification or exception whatsoever, and shall be made in
accordance with, but not subject to, the terms and conditions of this
Agreement under all circumstances (assuming that the Issuing Bank has
issued such Permitted Letter of Credit in compliance with the provisions
of Section 2.13), including, without limitation, any of the following
circumstances:

               (i)  any lack of validity or enforceability of this
          Agreement or any Note or Security Document;

               (ii) the existence of any claim, setoff, defense, or
          other right which the Company may have at any time against a
          beneficiary named in a New Permitted Letter of Credit or any
          transferee of any Permitted Letter of Credit (or any person
          for whom any such transferee may be acting), the Agent, any
          Bank, the Issuing Bank, or any person, whether in connection
          with this Agreement, any Permitted Letter of Credit, the
          transactions contemplated herein, or any unrelated
          transactions (including any underlying transactions between
          the Company and the beneficiary named in any Permitted Letter
          of Credit);

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

               (iv) the surrender or impairment of any security for
          the performance or observance of any of the terms of any Loan
          Document; or

               (v)  the occurrence of any Default or Event of Default.

     2.17 Payment of Reimbursement Obligations.

          (a)  The Company agrees to pay to the Issuing Bank the amount
of all Reimbursement Obligations, interest and other amounts payable to
the Issuing Bank under or in connection with any Permitted Letter of
Credit immediately when due, irrespective of any claim, set-off, defense,
or other right which the Company may have at any time against the Issuing
Bank or any other person.

          (b)  In the event any payment by the Company received by the
Issuing Bank with respect to a Permitted Letter of Credit and distributed
to the Banks on account of their respective participation is thereafter
set aside, avoided, or recovered from the Issuing Bank in connection with
any bankruptcy, reorganization, arrangement, insolvency, readjustment of
debt, dissolution or other liquidation law of any jurisdiction, each Bank
which received such distribution shall, upon demand by the Issuing Bank,
contribute such Bank's Ratable Share of the amount set aside, avoided, or
recovered together with interest at the rate required to be paid by the
Issuing Bank upon the amount required to be repaid by it.

     2.18 EXONERATION.  As between the Company, the Issuing Bank, each
other Bank and the Agent, the Company assumes all risks of the acts and
omissions of, or misuse of the  Permitted Letter of Credit issued by the
Issuing Bank by, the respective beneficiaries of such  Permitted Letter of
Credit.  In furtherance and not in limitation of the foregoing, subject to
the provisions of the  Permitted Letter of Credit applications, each of
the Issuing Bank, the other Banks and the Agent, in the absence of gross
negligence or intentional misconduct on its part, shall not be
responsible:

          (a)  for the form, validity, sufficiency, accuracy,
genuineness, or legal effect of any document submitted by any party in
connection with the application for and issuance of a  Permitted Letter of
Credit, even if it should in fact prove to be in any or all respects
invalid, insufficient, inaccurate, fraudulent, or forged; 

          (b)  for the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign a  Permitted
Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, which may prove to be invalid or ineffective for any
reason;

          (c)  for failure of the beneficiary of a  Permitted Letter of
Credit to comply duly with conditions required in order to draw upon such 
Permitted Letter of Credit;

          (d)  for errors, omissions, interruptions, or delays in
transmission or delivery of any messages, by mail, cable, telegraph,
telex, or otherwise, whether or not they be in cipher;

          (e)  for errors in interpretation of technical terms;

          (f)  for any loss or delay in the transmission or otherwise
of any document required in order to make a drawing under any  Permitted
Letter of Credit or of the proceeds thereof;

          (g)  for the misapplication by the beneficiary of such 
Permitted Letter of Credit; or

          (h)  for any consequences arising from causes beyond the
control of the Agent or any Bank (including the Issuing Bank) including,
without limitation, any act or omission, whether rightful or wrongful, of
any present or future de jure or de facto government or Governmental
Authority.

          IN FURTHERANCE AND EXTENSION AND NOT IN LIMITATION OF THE
SPECIFIC PROVISIONS HEREINABOVE SET FORTH, ANY ACTION TAKEN OR
OMITTED BY
THE ISSUING BANK UNDER OR IN CONNECTION WITH THE PERMITTED LETTERS
OF
CREDIT OR ANY RELATED CERTIFICATES, IF TAKEN OR OMITTED IN GOOD FAITH
AND
NOT CONSTITUTING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, SHALL NOT
PUT THE
AGENT, THE ISSUING BANK OR ANY OTHER BANK UNDER ANY RESULTING
LIABILITY TO
THE COMPANY OR RELIEVE THE COMPANY OF ANY OF ITS OBLIGATIONS
HEREUNDER TO
ANY SUCH PERSON.

     2.19 Reporting Requirements.  In addition to the reports required
by Section 7.01, the Company shall, no later than the tenth Business Day
following the last day of each month, provide to each Bank separate
schedules for each  Permitted Letter of Credit, in form and substance
satisfactory to the Agent, showing the date of issue, beneficiary, face
amount, expiration date, and the reference number of each  Permitted
Letter of Credit issued by the Issuing Bank which was outstanding at any
time during such month and the aggregate amount payable by the Company
during the month pursuant to Section 2.20.

     2.20 Compensation for Permitted Letters of Credit.

          (a)  Letter of Credit Fee.  The Company agrees to pay to the
Agent, for the account of each Bank, in the case of each Permitted Letter
of Credit, a letter of credit fee (the "Letter of Credit Fee") payable
quarterly in arrears equal to the greater of (i) the LIBOR Margin
multiplied by the average amount available to be drawn under such 
Permitted Letter of Credit during the quarter then ending multiplied by
the actual number of days during such quarter on which such Permitted
Letter of Credit was outstanding, divided by 360 and (ii) the actual
number of days during such quarter on which such Permitted Letter of
Credit was outstanding multiplied by $300, divided by 360.  The Company
shall also pay to the Agent, in the event of any extension or modification
of a  Permitted Letter of Credit which extends the expiration date or
increases the maximum amount available for drawing thereunder an
additional fee calculated and payable on the same basis as that set forth
in the first sentence of this Subsection 2.20(a) with respect to any such
extension or additional amount.  Whenever the Issuing Bank receives a
payment from the Company with respect to any fees incurred in connection
with any  Permitted Letter of Credit issued by the Issuing Bank, the
Issuing Bank shall promptly remit to the Agent, and the Agent shall
promptly remit to each Bank which has funded its participation in such 
Permitted Letter of Credit, in the currency provided for in such 
Permitted Letter of Credit and in same day funds, an amount equal to such
Bank's Ratable Share of such fees.

          (b)  Issuing Bank's Charges.  The Issuing Bank shall have the
right to receive, solely for its own account, such amounts as it and the
Company may agree, in writing, to compensate the Issuing Bank with respect
to issuance fees and the Issuing Bank's out-of-pocket costs of issuing and
servicing Permitted Letters of Credit.

          (c)  Increased Capital.  If either (i) the introduction of or
any change in or in the interpretation of any law or regulation, or (ii)
compliance by the Issuing Bank or any other Bank with any guideline or
request from any central bank or other Governmental Authority (whether or
not having the force of law) affects or would affect the amount of capital
required or expected to be maintained by it or any corporation controlling
it, and the Issuing Bank or such other Bank determines, on the basis of
reasonable allocations, that the amount of such capital is increased by or
is based upon its issuance or maintenance of or participation in, the
Permitted Letters of Credit then, upon demand by such Bank, the Company
shall immediately pay to the Agent (for the account of such Bank), from
time to time as specified by the Issuing Bank or such other Bank,
additional amounts sufficient to compensate such Bank therefor.  A
certificate as to such amounts submitted to the Company by such Bank
shall, in the absence of manifest error, be conclusive and binding for all
purposes.

3.   PREPAYMENT.

     3.01 Optional Prepayments.  The Company at any time and from time
to time on any Business Day may prepay the principal amount of any
Borrowings in whole or in part, without premium or penalty; provided that:

          (a)  The Company shall give to the Agent and each Bank not
less than five (5) full Business Days prior notice of each prepayment
specifying the aggregate principal amount of such Borrowings to be prepaid
and the prepayment date.  The Company's notice of such prepayment having
been given as aforesaid, the principal amount of the Loans comprising such
Borrowings specified in the notice, together with interest thereon to the
date of prepayment, shall become due and payable on such prepayment date;
and

          (b)  Prepayments of Loans made under this Section 3.01 on or
after the Conversion Date shall be applied, ratably, to such principal
installments of the Loans as the Company shall designate in its notice of
prepayment given pursuant to Subsection 3.01(a); provided that:

               (i)  if the Company does not so designate the principal
          installments of the Loans to which any of such prepayments is
          to be applied, such prepayment shall be applied ratably
          (according to each Bank's Ratable Share) to the principal
          installments due under the Loans in the inverse order of their
          respective due dates (the "Back End Installments");

               (ii) the Company may not designate the principal
          installments of the Loans to which any of such prepayment is
          to be applied, other than the Back End Installments, except in
          an amount that, when added to the sum of all other prepaid

be made on the next preceding Business Day.

5.   REPRESENTATIONS AND WARRANTIES.  The Company represents and
warrants:

     5.01 Organization and Qualification.  The Company and each

the laws of the state of their respective incorporation,  have the
corporate power to own their respective property and to carry on their
respective business as now conducted, and (c) are duly qualified as a
foreign corporation to do business and are in good standing in every

the case may be.  The Company is a Louisiana corporation and is a "citizen
of the United States" within the meaning of Section 101(13) of the Federal
Aviation Act and is an "air carrier" duly qualified as an "air taxi
commercial operator" within the meaning of said Act and the regulations
issued thereunder.  The corporations named in Exhibit B are the only
Subsidiaries of the Company on the Effective Date, and such Exhibit
accurately reflects the percentage of (x) the issued and outstanding
capital stock, and (y) the Voting Stock of each class of each Subsidiary
on the Effective Date and accurately identifies the Consolidated
Subsidiaries and the percentage of the Company's and each other
Subsidiary's ownership of the outstanding Voting Stock of each Subsidiary. 
The shares of capital stock of each Subsidiary owned by the Company have
been validly issued, are outstanding, fully-paid and non-assessable shares
of such Subsidiary and are owned by the Company free and clear of all
Liens (except statutory liens for taxes not yet due and for salaries of
clerical employees, none of which liens has been filed or perfected).

     5.02 Financial Statements.  The Company has furnished the Banks
with the following financial statements:   consolidated financial

1995 included in the Company's Annual Report on Form 10-K for the fiscal
year of the Company ended April 30, 1995 and accompanied by the report of
KPMG Peat Marwick, and  unaudited consolidated financial statements as at
and for the fiscal quarter of the Company ended January 31, 1996,
certified by the principal financial officer of the Company.  These
statements have been prepared in conformity with generally accepted
accounting principles consistently followed throughout the periods
involved and present fairly the consolidated financial condition of the
Company and the Consolidated Subsidiaries and the consolidated results of
operations of the Company and the Consolidated Subsidiaries as at the
dates and for the periods indicated, and neither the Company nor any
Consolidated Subsidiary has any material obligations or liabilities,
contingent or otherwise, not disclosed in the financial statements
described in clause (a) of this Section 5.02.  There has been no material
adverse change in the consolidated condition or operations, financial or
otherwise, of the Company and the Subsidiaries since April 30, 1995.

     5.03 Actions Pending.  There is no action or proceeding pending or,
to the knowledge of the Company, threatened against the Company or any
Subsidiary before any court or administrative agency which might result in
a material adverse change in the business or condition of the Company and
the Subsidiaries when taken as a whole.  There are no outstanding
judgments or awards against the Company or any Subsidiary.

     5.04 No Default.  Neither the Company nor any Subsidiary is in
default in any respect under the provisions of any instrument evidencing
any Indebtedness of the Company or such Subsidiary or of any agreement
relating thereto, or in default in any respect under any order, writ,
injunction or decree of any court, or in default in any respect under or
in violation of any order, regulation or demand of any governmental
instrumentality, which defaults or violations might have consequences
which would materially adversely affect the business, prospects, earnings,
properties or condition, financial or otherwise, of the Company and the
Subsidiaries, taken as a whole.  

     5.05 Warranty of Title; Leases.  The Company and each Subsidiary
have good and marketable title to their real property and valid and
indefeasible ownership interests in their other properties, free and clear
of all Liens other than Permitted Liens.  The Company has good and
marketable title to all the Collateral and has good right and full power
and authority to subject the Collateral to the Security Interest.  The
Collateral is free and clear of all Liens other than Permitted Liens.  The
Security Documents do, as of the Effective Date, constitute a first
mortgage on and first priority perfected security interest in the
Collateral subject only to Permitted Liens.  There is no financing
statement, chattel mortgage or notice thereof (including FAA Form 905,
"Aircraft Chattel Mortgage") or other security agreement or instrument or

now on file in any public office (including the Aircraft Registry) and not
canceled covering any of the Collateral other than those previously filed,
the effect of which has been terminated by termination statements or
releases (including FAA Form 8050-41) duly filed prior to the time of the
filing of any of the Security Documents for recordation in the Aircraft
Registry.  The Company and each Subsidiary have the right to, and do,
enjoy peaceful and undisturbed possession under all leases to which any of

the Company and each of its Consolidated Subsidiaries have been examined
and reported on by the Internal Revenue Service for all fiscal years to

officers know of no claims by any governmental authority for any unpaid
taxes.  There are no tax sharing agreements between the Company and any of
the Subsidiaries.

     5.07 Conflicting or Adverse Agreements or Restrictions.  Neither
the Company nor any Subsidiary is a party to any contract or agreement or
subject to any restriction which materially and adversely affects the
business or assets or financial condition of the Company and the
Subsidiaries when taken as a whole.  Neither the execution nor delivery of
this Agreement or the Notes nor compliance with the terms and provisions
hereof or of the Notes or any of the Security Documents will be contrary
to the provisions of, or constitute a default under, the charter or
by-laws of the Company or any Subsidiary or any law or any regulation,
order, writ, injunction or decree of any court or governmental
instrumentality or any agreement or instrument to which the Company or any
Subsidiary is a party or by which it is bound or to which it is subject.

owns any "margin stock" within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System (herein called "margin stock"). 
No part of the proceeds of any Borrowing will be used for the purpose of
purchasing or carrying any margin stock or for the purpose of reducing or
retiring any indebtedness which was originally incurred to purchase or
carry any margin stock.  No part of the proceeds of any Borrowing shall be
used for any purpose which might constitute the transactions contemplated
by this Agreement a "purpose" credit within the meaning of said Regulation
U, as now in effect or as it may hereafter be amended.  Neither the
Company nor any agent acting on its behalf has taken or will take any
action which might cause this Agreement, any Note or any Borrowing

the Board of Governors of the Federal Reserve System or to violate the
Securities Exchange Act of 1934, as amended, in each case as in effect now
or as the same may hereafter be in effect on the date of any Borrowing.

independent public accountants, are adequate have been established with
respect thereto and (iii) the Company's title to the affected portion of
the Collateral shall not be divested thereby and its right to use the

jurisdiction or jurisdictions (other than any actions contemplated,

to this Agreement or the Security Documents, including the execution,
delivery and recording of the Security Documents, the creation of the
Security Interest and any actions taken by the Agent or such Bank or in

the discharge of this Agreement, and, without limiting the generality of
Section 12.09, said obligations are herein assumed expressly for the
benefit of, and shall be enforceable by, the Agent, the Banks or any other
holder of an interest in any Note.

Marking.

          (a)  At its own cost and expense: (i) forthwith upon the
delivery thereof, cause each portion of the  Aircraft to be duly
registered, and at all times thereafter to remain duly registered, in the
name of the Company, under the Federal Aviation Act; it will not register
any portion of the Aircraft under the laws of any country other than the
United States of America as aforesaid and it will cause the Security
Documents to be duly recorded and maintained of record in the Aircraft
Registry and any other appropriate public offices as a first mortgage on,
and as creating a prior perfected security interest in, the Aircraft and
each portion thereof (including each portion which consists of an aircraft
engine of 750 or more rated takeoff horsepower, or the equivalent of that
horsepower, or a propeller capable of absorbing 750 or more rated takeoff
shaft horsepower); (ii) maintain, service, repair, overhaul and test the
Aircraft so as to maintain the Aircraft in such condition as may be
necessary to enable the airworthiness certification of the Aircraft to be
maintained in good standing at all times under the Federal Aviation Act,
and, in any event, in good repair, working order and operating condition,
ordinary wear and tear excepted, and in compliance with any applicable
requirements of law and of any governmental authority having jurisdiction
(regardless of upon which person such requirements shall, by their terms,
be nominally imposed), and from time to time it will make or cause to be
made all necessary or appropriate repairs, restorations, replacements and
renewals thereof and additions or improvements thereto, and in furtherance
thereof (subject to Section 9.01 and the provisions of this Agreement
specifying the obligations of the Company upon the occurrence of Events of
Loss) will promptly replace aircraft engines and all Parts of whatever
nature which, originally or from time to time, have been incorporated in
or installed as part of the Aircraft, or any portion thereof, and which
may from time to time become worn out, lost, stolen, destroyed, seized,
confiscated, damaged beyond repair or permanently rendered unfit for use
for any reason whatsoever, and each replacement portion shall be free and
clear of all Liens (other than Permitted Liens) and rights of others and
shall be in as good operating condition as, and shall have a value and
utility at least equal to that of, the replaced portion (assuming that
such replaced portion shall have been in the condition and state of repair
required to be maintained under the terms hereof); (iii) maintain all
records, logs and other materials required by the Federal Aviation
Administration, and any other governmental authority having jurisdiction,
to be maintained in respect of the Aircraft, regardless of upon which
person any such requirements shall, by their terms, be nominally imposed,
and the Company will comply with all applicable maintenance, service,
repair and overhaul manuals and service bulletins published by or on
behalf of the manufacturers of the Aircraft; (iv) at such times as any
Bank may reasonably request, through the Agent, furnish to the Agent, with
a copy to each Bank, statements regarding the condition and state of
repair of the Aircraft, in such detail as such Bank, through the Agent,
may reasonably request; and (v) procure and pay for all permits,
franchises, inspections and licenses necessary or appropriate in
connection with the Aircraft or any repair, restoration, replacement,
renewal, addition or improvement with respect to the Aircraft, the failure
to procure which might have an adverse effect on any Aviation Unit or
Units constituting a portion of the Aircraft, or any interest of the Banks
therein or in respect thereof.  The Company further covenants that the
Aircraft will not be (x) maintained, used or operated in violation of any
law or any rule, regulation or order of any governmental authority having
jurisdiction, or in violation of any airworthiness certification, license
or registration relating to the Aircraft issued by any such governmental
authority or (y) used or operated at any time that the full amount of
insurance required by Section 7.10 to be carried with respect thereto
shall not be in effect.  The Company further covenants (A) that no portion
of the Aircraft, the Appraised Value of which is used to determine the
Borrowing Base will be used, operated or situated at any time or for any
period outside the continental United States; and (B)(1) the Company shall
maintain with respect to the Aircraft used, operated or situated outside
the continental United States hull war risk insurance (including insurance
against war, strikes, riots, civil commotion, acts of persons for
political or terrorist purposes, malicious acts, acts of sabotage,
hijacking, confiscation and nationalization, except confiscation and
nationalization by the United States), extending throughout the world,
which insurance shall be made payable to the Agent, for the benefit of the
Banks under a standard mortgagee loss payable clause satisfactory to the
Agent and each Bank, or (2) the Company shall have entered into such other
protective arrangements with respect to such Aircraft used, operated or
situated outside the continental United States as shall be acceptable to
the Agent and each Bank.

          (b)  At all times affix to and maintain in each portion of
the Aircraft consisting of an Aviation Unit, adjacent to the airworthiness
certification therein, a metal nameplate bearing the following inscription
in plain, distinct and conspicuous lettering:

     "THIS EQUIPMENT IS OWNED BY PETROLEUM HELICOPTERS, INC.  SUBJECT TO
     A MORTGAGE IN FAVOR OF NATIONSBANK OF TEXAS, N.A., WHITNEY
NATIONAL
     BANK AND, FIRST NATIONAL BANK OF COMMERCE (THE "BANKS").  ANY
BUYER
     OR OTHER ENCUMBRANCER OF THIS EQUIPMENT IS HEREBY PUT ON NOTICE
THAT
     THE SALE OR CREATION OF AN ENCUMBRANCE BY PETROLEUM
HELICOPTERS,
     INC. TO OR IN FAVOR OF SUCH BUYER OR ENCUMBRANCER IS IN VIOLATION
OF
     THE AFORESAID MORTGAGE UNLESS AND UNTIL SUCH BUYER OR
ENCUMBRANCER
     SHALL HAVE RECEIVED FROM SAID NATIONSBANK OF TEXAS, N.A., AS AGENT
     FOR THE BANKS, A WRITTEN STATEMENT TO THE EFFECT THAT SUCH
EQUIPMENT
     HAS BEEN DULY RELEASED FROM THE SECURITY INTEREST OF SAID
MORTGAGE."

The Company will promptly replace any part of such nameplate which may be
removed, defaced or destroyed, and in the event that any person shall, in
accordance with the terms of this Agreement, succeed to the position of
the Company or the Banks named on any such nameplate, the Company will
promptly replace such nameplate with a nameplate inscribed with the name
of such successor.  Except as above provided, the Company will not permit
or suffer the name of any person other than the Company to be placed on
any portion of the Aircraft as a designation that might be interpreted as
a claim of ownership or a right to the possession or use thereof.

          (c)  Hangar the Aircraft principally in Lafayette Parish,
Louisiana, and although any Aviation Unit may from time to time, and for
various periods of time, operate in the normal course of business outside
said parish and state, it is intended and agreed that such Aviation Unit
shall remain principally hangared, and in that sense located, in Lafayette
Parish, Louisiana.

     7.10 Insurance with Respect to the Aircraft.

          (a)  Without limiting the generality of Section 7.03, at its
own cost and expense, maintain, with  insurers of recognized national
stature and responsibility satisfactory to the Agent and the Banks,
insurance policies insuring against loss or damage to the Aircraft from
such risks and in such amounts as a prudent person would maintain on
similar properties; provided, however, that, without the prior written
consent of the Agent and the Banks, the Company will not permit or suffer
the Aircraft to be insured on any basis or to any extent other than that
upon which the other Aviation Units in the Company's fleet shall be
insured, and, in any event, the Company will not permit or suffer the
amount of such insurance for each occurrence, less the deductible, if any,
with respect thereto, at any time to be less than the Appraised Value of
the Aircraft.  The policies required by this Subsection 7.10(a) to be
maintained shall name the Agent as an additional insured with respect to
the Aircraft and any payment of claims thereunder shall be made payable to
the Agent (without the necessity for the Company's joining in endorsing
any check or otherwise accepting any payment) under a standard mortgagee
loss payable clause satisfactory to the Agent and the Banks; provided,
however, that such policies may provide that, with respect to proceeds of
any particular claim in an amount not exceeding $50,000, such proceeds may
be paid by the insurers directly to the Company rather than to the Agent
unless an Event of Default or Default shall have occurred and be
continuing and the Agent shall have notified the insurer thereof.  To the
extent that such insurance coverage shall be available, such policies
shall further provide that (v) in respect of the interest of the Agent and
the Banks in such policies, the insurance shall not be invalidated by any
action or inaction of the Company or any other person, (w) the Agent's and
Banks' interest shall be insured regardless of any breach or violation by
the Company of any warranties, declarations or conditions contained in
such policies, (x) the insurers waive all rights of subrogation against
the Company, the Agent and each Bank, (y) the insurers waive any right to
any set-off, counterclaim or deduction, whether by attachment or
otherwise, in respect of any liability of the Company and (z) such
insurance will not be invalidated by any foreclosure or other remedial
proceedings or notices thereof relating to the Aircraft or any portion
thereof or interest therein, or by any change in the title to or ownership
of the Aircraft or any portion thereof or interest therein, or by the use
or operation of the Aircraft or any portion thereof for purposes more
hazardous, or in a manner more hazardous, than shall have been permitted
by such policies.  No such policy shall contain a provision reducing or
eliminating the liability of the insurer thereunder for any loss by reason
of the existence of other insurance policies covering the Aircraft or any
portion thereof against the peril involved, whether collectible or not. 
As between the Agent and the Banks and the Company, all insurance proceeds
received as the result of the occurrence of an Event of Loss shall be
applied in accordance with Subsection 9.02(a), and all insurance proceeds
received as the result of loss or damage not constituting an Event of Loss
shall be applied in accordance with Subsection 9.02(b).

          (b)  At its own cost and expense, maintain, with insurers of
recognized national stature and responsibility satisfactory to the Agent
and the Banks, insurance policies with respect to the Aircraft insuring
against loss or damage to the person and property of others from such
risks and in such amounts as a prudent person would maintain in similar
circumstances (including passenger legal liability insurance); provided,
however, that the Company will maintain public liability (including
passenger legal liability) and property damage insurance applicable to the
Aircraft in an amount which shall not be less than $20,000,000 per
accident, subject to a deductible not in excess of $50,000.  The policies
required by this Subsection 7.10(b) to be maintained shall name the Agent
for the equal and ratable benefit of the Banks as an additional insured
with respect to the Aircraft, and, to the extent available, shall insure
the Agent's and Banks' interest regardless of any breach of or violation
by the Company of any warranties, declarations or conditions contained in
such policies and shall provide that the insurers waive all rights of
subrogation against the Company, the Agent and each Bank and that the
insurers waive any right to any set-off, counterclaim or deduction,
whether by attachment or otherwise, in respect of any liability of the
Company.  No such policy shall contain a provision reducing or eliminating
the liability of the insurer thereunder for any loss by reason of the
existence of other insurance policies covering the Aircraft or any portion
thereof against the peril involved, whether collectible or not.

          Each insurance policy required by this subsection (b) to be
maintained by the Company shall expressly provide that all the provisions
thereof, except the limits of liability (which shall be applicable to all
insureds as a group) and liability for premiums (which shall be solely a
liability of the Company), shall operate in the same manner as if there
were a separate policy covering each insured.

          (c)  Upon request, furnish to the Agent, with a copy to each
Bank, and in any event within 120 days after the end of each fiscal year
of the Company, a certificate signed by the Company's independent
insurance broker or consultant summarizing the insurance then maintained
by the Company pursuant to this Section 7.10 and stating that, in the
opinion of said broker or consultant, such insurance complies with the
terms hereof.

          The Company will, and every insurance policy required by this
Section 7.10 to be maintained by the Company shall provide that the
insurer will, (i) advise the Agent and each Bank in writing promptly of
any default in the payment of any premiums or of any other act or omission
on the part of the Company of which it shall have knowledge and which
might invalidate or render unenforceable, in whole or in part, any such
insurance and (ii) advise the Agent and each Bank in writing, at least
thirty days prior thereto, of the expiration or cancellation or any
reduction or any material change in the coverage of any such insurance
(each such policy to provide that no such cancellation, reduction or
change will be effective until thirty days after such notice is given). 
The Company will advise the Agent and each Bank in writing promptly of any
notice or other communication received from any insurer by which such
insurer indicates that it may seek to suspend, terminate or change any
insurance required by this Section 7.10 to be maintained by the Company.

     7.11 Recording, Etc.  Forthwith upon the execution and delivery of
this Agreement and thereafter from time to time, cause the Security
Documents and all other documents and notices with respect thereto
(including financing statements and continuation statements, if any), to
be promptly filed, registered or recorded (and the Company will cause any
such filing, registration and recording to be continued in effect) to such
extent, in such manner and in such places (including the Aircraft
Registry) as may be necessary or appropriate under any present or future
law in order to publish notice of and fully to preserve and protect the
validity and priority of the Security Interest, and the interest of the
Agent and the Banks, in the property comprising or intended to comprise
the Collateral (including any portion of the Aircraft or any Part which
consists of an aircraft engine of 750 or more rated takeoff horsepower, or
the equivalent of that horsepower, or a propeller capable of absorbing 750
or more rated takeoff shaft horsepower), and from time to time will
perform or cause to be performed any and all other actions, and will
execute and deliver or cause to be executed and delivered and filed,
registered or recorded any and all other documents, that may be required
by applicable law or requested by any Bank for such publication,
preservation and protection.  The Company will pay or cause to be paid all
filing, registration and recording taxes and fees incident to such filing,
registration and recording, and all expenses incident to the preparation,
execution, delivery and acknowledgment of this Agreement, the Security
Documents, financing statements, continuation statements, if any, and
other such documents, and all stamp taxes and other taxes, duties,
imposts, assessments and charges arising out of or in connection with the
execution and delivery of this Agreement, the Security Documents,
financing statements, continuation statements and other such documents.

          The Company will deliver to the Agent (a) promptly after the
execution and delivery of any Security Document which subjects additional
Collateral to the Security Interest, an opinion of legal counsel
satisfactory to the Banks stating either (i) that such Security Document
and all other documents have been properly filed, registered and recorded
to the extent required by this Section 7.11, and reciting the details of
such action or referring to prior opinions of counsel in which such
details are given, or (ii) that no such action is necessary to maintain
the Security Interest, as so required, and (b) within 45 days after a
written request from the Agent or any Bank, but in no event more than once
during each calendar year, an opinion of legal counsel satisfactory to the
Banks (i) stating that all action has been taken with respect to the
filing, registration, recording, refiling, re-registration and
re-recording of the Security Documents and all other documents as is
necessary to maintain the Security Interest, as required under this
Agreement and the Security Documents (including the Security Interest on
any property acquired by the Company after the date of execution and
delivery of the Security Documents and owned on the date of such request
which is intended to be subject to the Security Interest), and reciting
the details of such action or referring to prior opinions of counsel in
which such details are given, and (ii) describing what if any action of
the foregoing character may reasonably be expected to become necessary in
the future to maintain the Security Interest, as so required, in the
Collateral.

     7.12 Material Adverse Change.  Notify each Bank promptly of the
occurrence of any material adverse change with respect to the business,
prospects, earnings, properties or condition, financial or otherwise, of
the Company or of the Company and the Subsidiaries taken as a whole since
April 30, 1995 (including, without limitation, any downward valuation by
the Company or any Subsidiary of the Aviation Units or any determination
by the Company or any Subsidiary that a significant portion of its
Receivables is uncollectible).  If at any time any Bank notifies the
Company through the Agent that it believes that the value of the Aircraft
to be less than the Appraised Value of the Aircraft, the Company will, at
its own cost and expense, forthwith submit to the Agent, with a copy to
each Bank, such new written opinions of the Independent Appraiser as the
Agent, or such Bank through the Agent, shall reasonably require.

     7.13 Further Assurances.  At any time and from time to time,
promptly, at its own cost and expense, the Company will do, execute,
acknowledge and deliver, or cause to be done, executed, acknowledged and
delivered, any and all such further acts, instruments, mortgages, security
agreements, financing statements, continuation statements and assurances
as the Agent or any Bank through the Agent shall reasonably require to
obtain the full benefits of the estates, interests, rights, powers,
privileges, and immunities granted herein and in the Security Documents
and for the better mortgaging, hypothecating, pledging, assuring and
confirming to or with the Banks, or for the protection or continuance of
protection of the validity and priority of the Security Interest in, all
or any portion of the Collateral by the Security Documents mortgaged,
hypothecated or pledged, or intended hereby or thereby to be mortgaged,
hypothecated or pledged, to or with the Banks or which the Company may be
or may hereafter become bound to mortgage, hypothecate or pledge to or
with the Banks.

     7.14 Change of Control.   Notify the Agent and each Bank forthwith
if at any time Carroll Wilson Suggs ("C.W. Suggs") shall cease to own the
Control Stock (hereinafter defined), and  at any time thereafter, upon the
written demand of the Agent given at the request of the Majority Banks,
pay to the Agent, for the ratable account of the Banks, the entire unpaid
principal amount of the Notes, together with accrued interest thereon on
the date specified in such demand, which date shall not be less than 30
days after the date of such demand; provided, however, if C.W. Suggs shall
cease to own the Control Stock solely because of the death of C.W. Suggs,
then, if and so long as the Control Stock is owned by the estate of C.W.
Suggs and the successor trustees of trusts created under the will of
Robert L. Suggs (the "Successor Trustees") (collectively, the "Substitute
Control Group"), such demand by the Agent shall be given only during the
period from and including the date that is 273 days after the death of
C.W. Suggs to and including the date that is 365 days after her death;
provided further that if at any time after the death of C.W. Suggs the
Control Stock shall cease to be owned by the Substitute Control Group, the
terms of the preceding proviso shall thereupon cease to apply and such
demand for payment may thereupon and at any time thereafter be given.  As
used in this Section 7.14, the term "Control Stock" shall mean that number
of shares of the capital stock of the Company which is sufficient to give
the holder or holders thereof the power to elect all of the members of the
board of directors of such corporation; Control Stock shall be deemed
"owned" only if owned both legally and beneficially; provided that in the
case of stock owned by the estate of C.W. Suggs, the interest therein of
heirs and devisees shall be disregarded until any of such stock is
transferred from the estate to any such heir or devisee; provided further
that for purposes of this Section 7.14, including for purposes of the

shortened, and (c) to the extent not described in Schedule III, Permitted

its obligations under this Agreement, the Notes or any of the Security
Documents, or cause or permit any part of any of such person's property to

9.   POSSESSION, USE, VALUATION AND RELEASE OF COLLATERAL; APPLICATION
OF
PROCEEDS THEREOF; ADDITIONS TO COLLATERAL.

     9.01 Possession and Use of Collateral.  Unless and until an Event
of Default shall have occurred and be  continuing, the Company may remain
in full possession, enjoyment and control of the Collateral (except any
Investment Securities deposited as security for the Notes with, and held
by, the Agent in accordance with the provisions of this Agreement), may
manage, operate and use the same and each portion thereof (except the
aforesaid Investment Securities) and may take and use the tolls, rents,
issues, profits, receipts, products, revenues and other income thereof,
except as otherwise expressly provided in this Agreement or any Security
Document; provided, however, that, as a condition to the foregoing
privilege of the Company, the possession, enjoyment, control, management,
operation and use of the Collateral shall at all times be maintained and
conducted in accordance with the requirements of this Agreement and the
Security Documents.

          Anything in this Agreement or the Security Documents to the
contrary notwithstanding, the Company may, at its own cost and expense,
remove from any Aviation Unit constituting a portion of the Aircraft, in
the ordinary course of maintenance, service, repair, overhaul or testing,
any aircraft engine or any Parts, whether or not worn out, destroyed,
seized, confiscated, damaged beyond repair or permanently rendered unfit
for use; provided, however, that the Company shall have fully complied
with the provisions of Subsection 7.09(a) of this Agreement as if such
removed aircraft engine or Parts shall have been worn out, lost, stolen,
destroyed, seized, confiscated, damaged beyond repair or permanently
rendered unfit for use.  Any aircraft engine and all Parts at any time
removed from any Aviation Unit constituting a portion of the Aircraft
shall, no matter where located, remain subject to the Security Interest
until the Company shall have fully complied with the provisions of Section
7.11 with respect to each such aircraft engine and such Part.

          It is expressly agreed that, anything herein contained to the
contrary notwithstanding, the Company shall remain liable under any and
all purchase orders and contracts relating to the construction or
acquisition of the Aircraft or any portion thereof to perform all its
obligations thereunder, all in accordance with and pursuant to the terms
and provisions thereof, and neither the Agent or any Bank shall have
liability under any of the foregoing by reason of or arising out of the
action taken by the Company in the granting of the Security Interest, nor
shall the Agent or any Bank be required or obligated in any manner to
perform or fulfill any obligation of the Company under or pursuant to any
such purchase orders or contracts.

          Upon, but not before, (a) the occurrence of an Event of
Default and the automatic acceleration of the Notes pursuant to clause (a)
of Section 10.02 or the making of the request or the granting of the
consent required by clause (b) of Section 10.02, the Agent may, with the
consent of the Majority Banks and shall upon the request of the Majority
Banks, notify any and all account debtors or obligors on the Receivables
of the Company to make payment on all such Receivables to the Agent for
application as provided in Section 10.05, and, subsequent to the
occurrence of an Event of Default, any proceeds of Receivables received by
the Company shall be held in trust by the Company for the account of the
Agent and the Banks, shall not be commingled with any other funds,
accounts, monies or property of the Company and, upon receipt thereof by
the Company shall be promptly accounted for, paid over, transmitted and
delivered to the Agent for the benefit of the Banks in the form received
by the Company.  The Company agrees to assist the Agent in all such
collection efforts.

          The Company hereby agrees that it will not, except as
expressly permitted by this Agreement, take, suffer or omit to take any
action the taking, suffering or omission of which might result in an
impairment of the Collateral or any portion thereof, or the Security
Interest therein.  Without limiting the generality of the foregoing, the
Company agrees that it will not sell, transfer or otherwise dispose of,
lease, or create or suffer to exist any Lien on, all or any portion of the
Collateral except as and to the extent permitted by the express terms of
this Agreement.

     9.02 Loss, Restriction, Requisition, Etc.

          (a)  If an Event of Loss shall occur, the Company shall
forthwith (and, in any event, within 20 days after  such occurrence) give
the Agent and each Bank notice of such Event of Loss.  Any amounts
received by the Agent representing payment of insurance proceeds or
payment from any governmental authority or other person with respect to
any condemnation, requisition, confiscation, theft or seizure of, or
requisition of title to or use of, or loss or damage to, the Aircraft or
any portion thereof resulting in the occurrence of such Event of Loss, net
of the direct expenses of collecting such insurance proceeds or other
payments and net of the taxes payable upon or occasioned by such Event of
Loss, shall be paid, ratably, to the Banks for application to the
principal installments due under the Loans in the inverse order of their
respective due dates.  If, as a result of such Event of Loss, the Company
shall not be in compliance with Subsection 8.16, the Company also shall,
within 40 days after the occurrence of such Event of Loss, (x) elect to
take one or more of the following actions in respect of such Event of Loss
and (y) give the Agent and each Bank notice of which action it has elected
to take (said written notice being hereinafter in this Subsection 9.02(a)
called the "Notice of Election"):

               (i)  the Company may deposit with the Agent for the
          equal and ratable benefit of the Banks, as security for the
          Notes and as a portion of the Collateral subject to the
          Security Interest, Pledged Investment Securities in an
          aggregate amount equal to the Appraised Value (determined
          prior to such Event of Loss) of the Aircraft affected by such
          Event of Loss and in respect of which Aviation Units shall not
          have been subjected to the Security Interest pursuant to
          clause (ii) below or the Notes shall not have been prepaid
          pursuant to clause (iii) below; and, in the event of the
          Company's election to take such action, the Company shall,
          within 30 days after the delivery of the Notice of Election,
          deposit such Pledged Investment Securities with the Agent at
          its principal office in Dallas, Texas (any such Investment
          Securities to be deposited and pledged with the Agent in such
          manner and pursuant to a pledge and security agreement, in
          form and substance satisfactory to all of the Banks, executed
          by the Company in favor of the Banks) (each such pledge and
          security agreement, together with all supplements,
          modifications and amendments thereto, herein referred to as a
          "Securities Pledge Agreement"); or

               (ii) the Company may subject to the Security Interest
          one or more helicopters or one or more other Aviation Units
          (provided, however, that any such other Aviation Units must be
          acceptable to the Agent and each Bank), having an aggregate
          Appraised Value (in the case of helicopters or other Aviation
          Units more than one year old, as specified by the Independent
          Appraiser in a written opinion addressed and delivered to the
          Agent and each Bank) at least equal to the Appraised Value
          (determined prior to such Event of Loss) of the Aircraft
          affected by such Event of Loss and in respect of which
          Investment Securities shall not have been pledged with the
          Bank pursuant to clause (i) above or the Notes shall not have
          been prepaid pursuant to clause (iii) below; and, in the event
          of the Company's election to take such action, the Company
          shall, within 45 days after the delivery of the Notice of
          Election, take Appropriate Actions; or

               (iii)     the Company may prepay principal on the Notes in
          an amount equal to the amount necessary to cause the Company
          to be in compliance with Subsection 8.16; and in the event of
          the Company's election to take such action, the Company shall,
          in the Notice of Election, specify the principal amount of the
          Loans to be repaid and designate a date for prepayment which
          shall be no later than 45 days after the date of the
          occurrence of such Event of Loss, and on such date such
          aggregate principal amount of the Loans, together with
          interest thereon to the date of such prepayment, shall become
          due and payable.  All such prepayments shall be applied as set
          forth in Subsection 3.02(d) and shall be paid without any
          premium or penalty except as provided in Subsection 3.02(d).

Upon or concurrently with full compliance by the Company with the
foregoing provisions of this Subsection 9.02(a), the Company may make
written request of the Agent to release from the Security Interest in
accordance with Subsection 9.05(b) any Aircraft which is the subject of an
Event of Loss.

          In the event that the Company shall deposit Pledged Investment
Securities with the Agent pursuant to clause (i) above, the Agent shall
deal with the same in accordance with the provisions of Subsection 9.02(c)
and the other provisions of this Agreement.  In the event that the Agent
shall receive any insurance proceeds or payments from any governmental
authority or other person in connection with the occurrence of such Event
of Loss, such amounts shall be held by the Agent as a portion of the
Collateral and may be invested in accordance with the provisions of
Subsection 9.02(c).  Such amounts shall be paid to the Company upon
written request by the Company, but only after the Company shall have
fully complied with the foregoing provisions of this Subsection 9.02(a)
and only if, at the time of such payment, the Agent or any Bank shall not
have any knowledge or notice that any Default or Event of Default shall
have occurred and then be continuing, or will exist immediately after such
payment.

          (b)  If any Aircraft or any portion thereof shall be
condemned, requisitioned, confiscated, stolen, seized, lost or damaged or
its title or use requisitioned, and such action shall not result in an
Event of Loss, the Company will promptly take the action required by
Section 7.09 with respect to the repair and replacement thereof, and, in
the event of any such condemnation, requisition, confiscation, requisition
of title or use, the Company will forthwith (and, in any event, upon the
earlier of the Business Day next preceding the date upon which a Borrowing
Base Certificate is to be delivered hereunder or 10 days after such
occurrence) notify the Banks in writing and, forthwith upon receipt by the
Company, will deposit with the Agent any award or purchase price received
by the Company in connection therewith (the Company hereby assigning to
the Agent for the equal and ratable benefit of the Banks all its rights
and interest in and to any and all such awards or purchase price and
hereby agreeing to execute and deliver, upon the request of the Agent or
any Bank, any and all assignments and other instruments deemed by the
Agent or such Bank to be necessary or desirable for the purpose of
confirming or further evidencing the assignment by the Company of the
aforesaid awards or purchase price to the Agent for the benefit of the
Banks free and clear of any and all Liens of any kind or nature whatsoever
created by the Company).  Any amounts received by the Agent representing
payment of insurance proceeds or payment from any governmental authority
or other person with respect to any condemnation, requisition,
confiscation, theft or seizure of, or requisition of title to or use of,
or loss or damage to, the Aircraft or any portion thereof that shall not
result in an Event of Loss will be applied by the Agent to reimburse the
Company for (but only after its completion of) the repair or replacement
of the affected portion of the Aircraft, but such reimbursement shall be
made only if no Default or Event of Default shall have occurred and be
continuing and upon receipt by each Bank, in form and substance
satisfactory to such Bank, of an Officers' Certificate requesting such
reimbursement, describing the costs incurred by the Company for which it
is requesting reimbursement and certifying that (i) there is not any
outstanding Indebtedness for the purchase price or construction of said
repairs or replacements, or for labor, wages, materials or supplies in
connection with the making thereof, which, if unpaid, might become the
basis for a vendor's, mechanic's, laborer's, materialman's, statutory or
other similar lien upon said repairs or replacements or any portion
thereof, or which might materially impair the security afforded by said
repairs or replacements; (ii) no Default or Event of Default has occurred
and is then continuing, or will exist immediately after such
reimbursement; (iii) no part of the amount requested for reimbursement has
been or is being made the basis, in any previous or then pending
application, for the withdrawal of any other proceeds under this
subsection (b); and (iv) the affected portion of the Aircraft, as so
repaired or replaced, is of a value not less than the value thereof
immediately preceding such condemnation, requisition, confiscation, theft,
seizure, requisition of title or use, loss or damage and, in any event, is
in the condition required by Section 7.09 to be maintained.  With respect
to any particular loss as to which the insurance proceeds shall not exceed
$50,000 and which shall have been paid to the Company, such proceeds shall
be applied by the Company (and the Company, by acceptance of such
proceeds, covenants so to apply such proceeds) to the cost of repairing,
restoring or replacing the property destroyed or damaged; and any portion
of such proceeds remaining after such application may be retained by the
Company.

          (c)  All Pledged Investment Securities deposited with the
Agent as security for the Notes, pursuant to Subsection 9.02(a)(i) or any
other provision of this Agreement, and all insurance proceeds and payments
from any governmental authority or other person received by the Agent in
connection with any loss or taking of, or damage to, the Collateral, shall
be held by the Agent for the benefit of the Banks as a portion of the
Collateral.  Any such proceeds and payments shall be invested and
reinvested by the Agent in Investment Securities in accordance with
written instructions received from the Company, and Investment Securities
purchased with such proceeds and payments shall also be held by the Agent
for the benefit of the Banks as Pledged Investment Securities constituting
a portion of the Collateral.  The interest accruing on all Pledged
Investment Securities held by the Agent, and any profit realized from the
investment of such proceeds and payments or the sale of Pledged Investment
Securities held by the Agent (hereinafter, net of commissions and
expenses, collectively called "Pledged Investment Securities Gains"),
shall be held by the Agent for the account of the Company (but subject to
the Security Interest), and shall be paid to or at the direction of the
Company from time to time upon written request by the Company if, at such
time, neither the Agent nor any Bank shall have any knowledge or notice
that a Default or Event of Default shall have occurred and then be
continuing, or will exist immediately after such payment.  Amounts equal
to losses, if any, attributable to such Pledged Investment Securities
deposited with the Agent and specified in any report delivered by the
Agent to the Company pursuant to the next sentence shall be paid to the
Agent, to be held as a portion of the Collateral, by the Company within 5
days after the delivery to the Company by the Agent of such report. 
Within 15 days after the end of each calendar month during which any
Pledged Investment Securities shall be held by the Agent as a portion of
the Collateral, the Agent shall deliver to the Company a written report of
the earnings and losses, if any, attributable to such Pledged Investment
Securities during the preceding calendar month, or the portion thereof
during which such Pledged Investment Securities shall have been held by
the Agent as a portion of the Collateral.  Upon the payment by the Agent
to the Company of any Pledged Investment Securities Gains in accordance
with the foregoing provisions of this subsection (c), the amount of such
Pledged Investment Securities Gains so paid shall be deemed to have been
released from the Security Interest.

          In addition to the payment of Pledged Investment Securities
Gains and the release thereof from the Security Interest in accordance
with the preceding paragraph, and without limiting the generality of any
other provisions of this Agreement, the Agent may, with the consent of the
Banks, make payment of and deliver Pledged Investment Securities to or at
the direction of the Company, and may, with the consent of the Banks,
release the same from the Security Interest, upon the written request of
the Company, the presentation to the Agent and the Banks of any documents
(including appropriate termination statements or releases), in form and
substance satisfactory to the Agent and each Bank, presented to the Agent
and each Bank by the Company and necessary to release the same from the
Security Interest, and the taking by the Company of all the actions
specified in Subsection 9.02(a)(ii) to subject to the Security Interest
one or more additional helicopters or other Aviation Units having an
aggregate Appraised Value equal to or greater than the aggregate amount of
the Pledged Investment Securities to be released from the Security
Interest.

          Any Aircraft subject to an Event of Loss or subject to the
provisions of Subsection 9.02(b) shall not be included in Aircraft for the
purpose of determining the Borrowing Base.

     9.03 Valuation of Aircraft, Etc.

          (a)  The Company will deliver or cause to be delivered to the
Agent and each Bank on or before June 15 in  each calendar year,
commencing June 15, 1996, (i) with respect to any Aircraft that shall at
the time be new or not more than one year old, an Officers' Certificate
certifying the purchase price thereof, and having attached thereto a
schedule of all the Aircraft showing the Appraised Value of each Aviation
Unit constituting a portion thereof for that year and the immediately
prior year and (ii) with respect to any Aircraft that shall at the time be
more than one year old, a written opinion of the Independent Appraiser,
dated as of a date after April 30 of that year and addressed to the Agent
and each Bank, specifying the "purchase price" (as referred to in and
determined in accordance with clause (ii) of the definition of "Appraised
Value" set forth herein) of such Aircraft as of such date.  The written
opinion referred to in clause (ii) of the preceding sentence shall (x)
state that the Independent Appraiser has, on or after April 30 of that
year, made such a physical inspection, if any, of each helicopter or other
Aviation Unit covered by said written opinion as he deems necessary or
appropriate for the purposes of such opinion; (y) indicate, for each such
helicopter or other Aviation Unit, (aa) the make and model, manufacturer's
serial number and the United States registration number thereof, (bb) the
month and year of purchase thereof by the Company, (cc) the original
purchase price thereof and (dd) the "purchase price" thereof referred to
in and determined in accordance with clause (ii) of the definition of
"Appraised Value" set forth herein; and (z) otherwise be satisfactory in
form and substance to the Agent and each Bank.  In the event that, after
receiving any such annual written opinion of the Independent Appraiser,
any Bank shall deliver to the Company and the Agent a written request for
a new written opinion and a written statement of the reasons for its
objection to the annual opinion, the Company shall cause the Independent
Appraiser to deliver to the Agent, with a copy to each Bank, within 30
days after the receipt by the Company of such written request, a new
written opinion, dated as of a date within such 30-day period, with
respect to the matters referred to in clause (ii) of the first sentence of
this Subsection 9.03(a); provided, however, that, if the Company shall
not, within 45 days after the delivery to the Agent and the Banks of any
annual written opinion, have received a written request for a new written
opinion pursuant to the preceding sentence, the Agent and the Banks shall
be deemed to have permitted the Company to use such annual written opinion
as the basis for determining the "Appraised Value" of Aircraft for
purposes of this Agreement, including, without limitation, as the basis
for complying with its obligations under Subsection 9.03(b).  In the event
any Bank shall request a new written opinion pursuant to the preceding
sentence, the Agent and the Banks shall be deemed to have permitted the
Company to use the most recent annual written opinion delivered by the
Independent Appraiser as the basis for determining the "Appraised Value"
of Aircraft for purposes of this Agreement until such new written opinion
is delivered.

          (b)  In the event that for any reason, other than the
occurrence of an Event of Loss, the aggregate outstanding principal
amounts of the Loans and the aggregate amount of Permitted Letter of
Credit Amounts shall, at any time, exceed the Borrowing Base as shown on
the most recently delivered Borrowing Base Certificate, then, the Company
may, in lieu of the mandatory prepayment required pursuant to Subsection
3.02(b): (i) take all the actions described in Subsection 9.02(a)(ii) for
the purpose and with the effect of subjecting to the Security Interest one
or more helicopters or one or more other Aviation Units (provided,
however, that any such other Aviation Units must be acceptable to the
Agent and the Banks) having an aggregate Appraised Value in an amount
which, when added to the aggregate Appraised Value of the Aircraft then
subject to the Security Interest,  the amount of Pledged Investment
Securities then held by the Agent subject to the Security Interest and 80%
of the amount of Eligible Receivables, would cause the Company to be in
compliance with the provisions of Section 8.16; or (ii) deposit Pledged
Investment Securities with the Agent pursuant to a Securities Pledge
Agreement in such an amount that will cause the Company to be in
compliance with Section 8.16; provided, however, notwithstanding the time
periods set forth in Subsection 9.02(a)(ii), any action taken by the
Company pursuant to this Subsection 9.03(b) must be taken within 3
Business Days of the date upon which the Company or any Bank determines
that the Company is not in compliance with Section 8.16.

     9.04 Protection of Purchasers.  No purchaser of property purporting
to be released under this Agreement shall be bound to ascertain the
authority of the Agent and the Banks to execute any documents effecting
such release, or to inquire as to any facts required by the provisions of
this Agreement to exist as a condition to the proper exercise of such
authority.

     9.05 Other Additions to Collateral; Releases of Collateral

          (a)  Other Additions to Collateral.  Within 30 days after
purchasing any Aviation Unit that the Company desires or is required by
Subsection 2.02(b) to include in the calculation of the Borrowing Base,
the Company will grant a first priority security interest in such Aviation
Unit to the Banks to secure the Company's obligations hereunder and under
any other documents executed in connection herewith or contemplated
hereby, whereupon such Aviation Unit shall constitute a portion of the
Collateral subject to the Security Interest.  Without limitation on the
foregoing, within 30 days after the purchase of such Aviation Unit, the
Company shall take Appropriate Actions.

          (b)  Releases of Collateral.  (i) If the Company determines
that it is in the best interest of the Company to transfer ownership of
one or more Aviation Units that comprise a portion of the Aircraft or
exchange one or more Aviation Units that comprise a portion of the
Aircraft for one or more other Aviation Units, then upon the delivery of
an Officers' Certificate stating the United States registration number of
the Aviation Unit to be transferred or exchanged and the date (which shall
not be less than 14 nor more than 90 days from the date of such Officers'
Certificate) that the Company intends to consummate such transaction, the
Company may request that the Agent, on behalf of the Banks, release from
the Security Interest the Aircraft to be transferred or exchanged and the
Agent, on behalf of the Banks, within a reasonable time after such request
and in any event on or before the date on which the Company consummates
such transaction, shall execute all documents (including all appropriate
termination statements and releases) required to effect such release,
provided that (A) (I) the Company shall provide the Aviation Unit to be
received by it in any such exchange for inclusion in the Security Interest
pursuant to Subsection 9.05(b)(ii), and the sum of the Appraised Value of
said Aviation Unit, as reflected on a certificate of an Independent
Appraiser, in form and substance acceptable to the Agent, plus the amount
of any cash to be received by the Company as additional consideration for
the Aviation Unit being transferred, shall be greater than or equal to the
Appraised Value, as reflected on a certificate of an Independent
Appraiser, in form and substance acceptable to the Agent, of the Aviation
Unit to be released, and the Company shall pay to the Agent for the
ratable benefit of the Banks all proceeds, if any, from such sale, net of
direct expenses of, and taxes payable upon or occasioned by, such sale, to
be applied to the principal installments due under the Loans according to
the terms and conditions of Subsection 3.02(c), or (II) in the event the
Company is selling one or more Aircraft, the Company shall pay to the
Agent for the ratable benefit of the Banks the proceeds of such sale, net
of direct expenses of, and taxes payable upon or occasioned by, such sale
to be applied to the principal installments due under the Loans according
to the terms and conditions of Subsection 3.02(c), and (B) no Default or
Event of Default has occurred and is continuing or would result from the
release of the Aircraft to be transferred or exchanged by the Company, and
the Company shall have delivered to the Agent an Officers' Certificate to
such effect in the form of Exhibit E to this Agreement.

               (ii) For each Aviation Unit that the Company desires or
          is required to include in the Security Interest as a
          substitute for an Aviation Unit to be released pursuant to
          Subsection 9.05(b)(i), the Company shall, upon its acquisition
          thereof, grant a first priority security interest in such
          Aviation Unit to the Banks to secure the Company's obligations
          hereunder and under any other documents executed in connection
          herewith or contemplated hereby, whereupon such Aviation Unit
          shall constitute a portion of the Collateral subject to the
          Security Interest.  Without limitation on the foregoing,
          within 30 days after the earlier of the Company's acquiring
          the Aviation Unit to be subjected to the Security Interest or
          the Agent's release of the Aircraft pursuant to Subsection
          9.05(b)(i), the Company shall take Appropriate Actions.

               (iii)     The Agent shall be absolutely entitled to rely on
          the Officers' Certificates and certificates of Independent
          Appraisers and opinions of counsel referred to in the
          definition of "Appropriate Actions" and (b) for the veracity
          of each of the statements made therein absent actual knowledge
          to the contrary on the part of the officer of the Agent
          executing the documents relating to such release or addition. 
          The Agent shall not be required to investigate or verify any
          statement made in such Officers' Certificates and certificates
          of Independent Appraisers and opinions of counsel and any
          investigation that the Agent shall elect to undertake shall
          not affect its ability to rely on such Officers' Certificates
          and Certificates of Independent Appraisers and opinions of
          counsel.

               (iv) As long as there is no Default or Event of
          Default, each of the Banks hereby authorizes the Agent to
          execute and deliver (and, where appropriate, as determined by
          the Agent in its sole and independent discretion, to authorize
          others to execute and deliver on its behalf) on behalf of the
          Banks, all documents required to effect the release of the
          Aviation Unit and the addition of one or more substitute
          Aviation Unit received by the Company, if any, under the
          Security Interest.

               (v)  At no one time shall there be more than three (3)
          Aircraft that are the subject of releases from the Security
          Interest unless all requirements set forth in this Subsection
          9.05(b) with respect thereto and with respect to the Aviation
          Units to be subjected to the Security Interest in place
          thereof have been satisfied.

Default hereunder:

premium thereon, when due (whether by scheduled maturity, mandatory
prepayment, acceleration, demand or otherwise) and such failure shall
continue after the applicable grace period, if any, specified in the
agreement or instrument relating to such Indebtedness if the effect of
such failure is to permit the holder of such Indebtedness for Money
Borrowed to declare such Indebtedness for Money Borrowed due prior to its
stated maturity, or any other condition shall exist or event occur
permitting any Indebtedness for Money Borrowed (other than Indebtedness
evidenced by the Notes) owing by the Company or any Subsidiary to become
or be declared due prior to its stated maturity; or

          (c)  Any material representation or warranty made by the

debt, dissolution or other liquidation law of any jurisdiction; or

          (i)  Any such application is filed, or any such proceedings
are commenced, against the Company or any Subsidiary, and the Company or
such Subsidiary indicates its approval, consent or acquiescence, or an
order is entered appointing a trustee or receiver or custodian, or
adjudicating the Company or any Subsidiary bankrupt or insolvent, or
approving the petition in any such proceedings, and such order remains in
effect for 60 days; or

any "prohibited transaction" (as defined in Section 406 of ERISA or
Section 4975 of the Code) which can be expected to result in a material
liability to the Company; (ii) any material "accumulated funding
deficiency" (as defined in Section 302 of ERISA or Section 412 of the
Code), whether or not waived, shall exist with respect to any PBGC Plan or
Multiple Employer Plan, if in the reasonable judgment of the Majority
Banks, such accumulated funding deficiency would give rise to a material
liability of the Company; (iii) the Company, any Subsidiary or any ERISA
Affiliate shall apply for or be granted a funding waiver under Section 302
of ERISA or Section 412 of the Code, which waiver or request for waiver is

Event not subject to the provision for thirty-day notice to the PBGC under
applicable PBGC regulations) shall occur with respect to any PBGC Plan or

to give rise to a material liability of the Company or any Subsidiary; (v)
proceedings shall commence to have a trustee appointed or a trustee shall
be appointed to terminate or administer a PBGC Plan or a Multiple Employer

to give rise to a material liability of the Company or any Subsidiary with
respect to such termination; (vi) a notice of intent to terminate a PBGC
Plan or Multiple Employer Plan under Section 4041(c) is filed with the

Majority Banks, would likely subject the Company, any Subsidiary or any
ERISA Affiliate to material liability; or (ix) any event or condition
described in (i) through (viii) above (determined without regard to
whether the event or condition taken alone would or could result in a
material liability) shall occur or exist with respect to a PBGC Plan, a
Multiple Employer Plan or a Multiemployer Plan which individually or in
combination with one or more of any events described in clauses (i)
through (viii) above (determined without regard to whether the event or
condition taken alone would or could result in a material liability), if
any, in the opinion of the Majority Banks would likely, subject the
Company, any Subsidiary or any ERISA Affiliate to any material tax,
penalty or other liability; provided that for the purposes of this
Subsection 10.01(l), an obligation or liability shall be considered
material if it equals or exceeds $500,000; or

          (m)  The Company does not pay any dividend on any of its
capital stock as declared or permits any dividend to accumulate on any of
its capital stock in respect of which cumulative dividends are provided
for.

     10.02     Acceleration of Maturity.  Upon (a) the occurrence of any
Event of Default described in Subsection 10.01(g), 10.01(h), 10.01(i) or
10.01(j) with respect to the Company, the unpaid principal amount of and
accrued interest on the Notes and the Loans shall automatically become
immediately due and payable, together with all other amounts payable under
this Agreement or any Security Document, and the obligation of each Bank
to make Loans and the capacity of NationsBank to issue Permitted Letters
of Credit shall automatically terminate, without presentment, demand,
protest or further notice (including, without limitation, notice of
acceleration and notice of intent to accelerate) of any kind, all of which
are hereby expressly waived by the Company and (b) the occurrence of any
other Event of Default, the Agent shall at the request, and may with the
consent, of the Majority Banks, by notice to the Company, (i) declare the
obligation of each Bank to make Loans and the ability of NationsBank to
issue Permitted Letters of Credit to be terminated whereupon the same
shall forthwith terminate, and (ii) declare the unpaid principal amount of
and accrued and unpaid interest on the Notes and the Loans, together with
all other amounts payable under this Agreement or any Security Document,
to be forthwith due and payable, whereupon the principal amount of and
accrued and unpaid interest on the Notes and the Loans, and all such other
amounts, shall become and be forthwith due and payable, without
presentment, demand, protest or further notice (including, without
limitation, notice of acceleration and notice of intent to accelerate) of
any kind, all of which are hereby expressly waived by the Company.  Upon
the occurrence of any such Event of Default and the acceleration of the
unpaid principal amount of and accrued and unpaid interest on the Notes
and the Loans and all other amounts due hereunder and under the Security
Documents, the Agent shall at the request, and may with the consent, of
the Majority Banks, proceed to protect and enforce the rights of the Banks
either by suit in equity or by action at law or both, whether for the
specific performance of any covenant or agreement contained in this
Agreement or in any Security Document or in aid of the exercise of any
power granted in this Agreement or in any Security Document; or may
proceed to enforce the payment of the indebtedness outstanding under the
Notes, hereunder and under or secured by the Security Documents and
interest thereon in the manner set forth therein; it being intended that
no remedy conferred herein or in any other Security Document shall be
exclusive but shall be in addition to every other remedy given hereunder
and under the Security Documents or now or hereafter existing at law or in
equity or by statute or otherwise.

     10.03     Right of Set-off.  Upon (a) the occurrence and during the
continuance of any Event of Default and (b) either automatic acceleration
of the Notes pursuant to clause (a) of Section 10.02 or the making of the
request or the granting of the consent required by clause (b) of Section
10.02 to declare the Notes due and payable pursuant to the provisions of
Section 10.02, each Bank is hereby authorized, to the extent permitted by
applicable law, at any time and from time to time, without notice to the
Company (any such notice being expressly waived by the Company), 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 (whether or
not then due and payable) at any time owing by such Bank to or for the
credit or the account of the Company, against any and all of the
obligations of the Company now or hereafter existing under this Agreement,
the Notes or any of the Security Documents, irrespective of whether or not
such Bank shall have made any demand for satisfaction of such obligations
and although such obligations may be unmatured or portions thereof may be
owing to Banks other than the Banks effecting such set-off and
application.  Each Bank agrees to notify the Company and the Agent
promptly after any such set-off and application made by such Bank,
provided that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of each Bank under
this Section 10.03 are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which such Bank
may have hereunder, under any of the other Security Documents or under any
applicable law.

     10.04     Sharing of Payments, Etc.  If at any time, whether before or
after the occurrence of an Event of Default, any Bank shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right
of set-off or otherwise) of principal, interest or Commitment Fees on
account of the Notes held by it in excess of its Ratable Share of such
payments, such Bank shall purchase from the other Banks such
participations in the Notes held by them as shall be necessary to cause
such purchasing Bank to share the excess payment ratably with each of
them, provided, however, that if all or any portion of such excess payment
is thereafter recovered from such purchasing Bank, such purchase from each
Bank shall be rescinded and such Bank shall repay to the purchasing Bank
the purchase price to the extent of such recovery together with an amount
equal to such Bank's ratable share (according to the proportion of  the
amount of such Bank's required repayment to  the total amount so recovered
from the purchasing Bank) of any interest or Commitment Fee paid or
payable by the purchasing Bank in respect of the total amount so
recovered.  The Company agrees that any Bank so purchasing a participation
from another Bank pursuant to this Section 10.04 may exercise all its
rights of payment (including the right of set-off) with respect to such
participation, at any time, as fully as if such Bank were the direct
creditor of the Company in the amount of such participation.

     10.05     Application of Proceeds of Collateral.  (a)  All moneys
received by the Agent as a result of the enforcement of the rights and
remedies of the Agent or the Banks pursuant to the Security Documents
shall be distributed by the Agent on the dates fixed by the Agent
(individually a "Distribution Date" and collectively, the "Distribution
Dates") as follows:

     FIRST:    to the Agent in payment of the amount of any and all
               unreimbursed expenses of the Agent, including, without

               and of any agents and experts employed by the Agent,
               incurred by the Agent prior to the relevant Distribution
               Date in connection with (w) the administration of this
               Agreement and the Security Documents, (x) the custody,
               preservation, use or operation of, or the sale of,
               collection from, or other realization upon any assets of
               the Company pursuant to the Security Documents (y) the
               exercise or enforcement of any of the rights of the
               Agent hereunder or under the Security Documents or (z)
               the failure by the Company to perform or observe any of
               the provisions of this Agreement or any Security
               Document;

     SECOND:   to the Banks in an amount equal to the sum of the unpaid
               principal of and interest on the Notes plus the
               aggregate amount of Permitted Letter of Credit Amounts
               (excluding all such Amounts which the issuing Bank of
               any Permitted Letters of Credit has paid to the
               beneficiary thereof and has been reimbursed therefor by
               the Company), and accrued interest thereon, if any, and,
               in the event such moneys shall be insufficient to pay in
               full such amount, then to the payment thereof ratably to
               each Bank in the same proportion which (x) the sum of
               aggregate unpaid principal of and interest on the Notes
               held by such Bank plus the aggregate amount of
               unreimbursed Permitted Letter of Credit Amounts and
               accrued interest thereon (excluding therefrom an amount
               equal to that portion of such interest calculated at a
               rate per annum in excess of the rate per annum provided
               for under Subsection 2.03(b), such excluded amount being
               the "Excess Interest"), if any, in respect of Permitted
               Letters of Credit issued by such Bank bears to (y) the
               sum of the aggregate unpaid principal of and interest on
               the Notes plus the aggregate amount of Permitted Letter
               of Credit Amounts and accrued interest thereon
               (excluding therefrom an amount equal to the aggregate
               Excess Interest), if any, on the relevant Distribution
               Date (all such partial prepayments to be applied by each
               Bank first to the payment of accrued and unpaid interest
               on the Notes and Permitted Letter of Credit Amounts, if
               any, of such Bank, then to the payment of principal
               thereon and finally pursuant to the documents evidencing
               the Permitted Letter of Credit Amounts, if any, of such
               Bank); provided, however, in the event any Bank that has
               issued a Permitted Letter of Credit does not for any
               reason apply its portion of the proceeds of the
               Collateral as provided herein within 30 days after the
               expiration date of such Permitted Letter of Credit, such
               Bank shall return all such unapplied proceeds to the
               Agent for distribution to the Banks for the ratable
               application to any unpaid obligations held by the Banks
               in respect of the Notes and any other Permitted Letters
               of Credit;

     THIRD:    to the Banks in an amount equal to the sum of unpaid
               commitment and agent's fees payable under this Agreement
               plus the fees, if any, due in respect of any Permitted
               Letters of Credit (collectively the "Fees"), whether
               matured or unmatured, and, in the event such moneys
               shall be insufficient to pay in full such amount, then
               to the payment thereof ratably to each Bank in the same
               proportion which the aggregate amount of Fees due to
               such Bank bears to the aggregate unpaid Fees due to all
               the Banks on the relevant Distribution Date;

     FOURTH:   to the Banks in an amount equal to the aggregate Excess
               Interest plus all other amounts due under this Agreement
               and the Security Documents (collectively the "Other
               Amounts"), and in the event such moneys shall be
               insufficient to pay in full such amount, then to the
               payment thereof ratably to each Bank in the same
               proportion which the aggregate amount of Other Amounts
               due such Bank bears to the aggregate unpaid Other
               Amounts due to all the Banks on the relevant
               Distribution Date; and

     FIFTH:    any surplus then remaining shall be paid to the Company,
               or to its successors and assigns, or to whomsoever may
               be lawfully entitled to receive the same, or as a court
               of competent jurisdiction may direct.

          (b)   The term "unpaid" as used in this Section 10.05 shall
mean all obligations outstanding as of a Distribution Date as to which
prior distributions have not been made, after giving effect to any
adjustments which are made pursuant to Section 10.04 and of which the
Agent shall have been notified.

11.  THE AGENT.

     11.01     Appointment of Agent; Authority.  Each of the Banks
irrevocably appoints and authorizes the Agent to  act on its behalf under
this Agreement and under the Security Documents, and to exercise such
powers hereunder and thereunder as are specifically delegated to or
required of the Agent by the terms hereof and thereof, together with such
powers as may be reasonably incidental thereto.  As to (i) any action
which is discretionary with the Agent under the provisions hereof or of
the Notes or the Security Documents or (ii) any action not expressly
required of the Agent by this Agreement, the Notes and the Security
Documents (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of all of the Banks, and such instructions shall be binding
upon all Banks and all holders of Notes; provided, however, that the Agent
shall not be required to take any action which, in the reasonable opinion
of the Agent, either exposes the Agent to personal liability or is
contrary to this Agreement, any Note, any Security Document or applicable
law.

     11.02     INDEMNIFICATION OF AGENT.  The Agent shall not be required to
take any action hereunder or to prosecute or defend any suit in respect of
this Agreement, the Notes or the Security Documents, unless indemnified to
its satisfaction by the Banks against loss, cost, liability and expense. 
If any indemnity furnished to the 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 EACH OF THE BANKS
AGREES TO INDEMNIFY the Agent, its officers, directors, employees,
attorneys and agents (each an "Indemnified Party") (to the extent not
reimbursed by the Company), ratably according to such Bank's Ratable
Share, 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 Indemnified Party in any way
relating to or arising out of this Agreement, the Security Documents, or
the Notes, or any of them, or any action taken or omitted by such
Indemnified Party under this Agreement, the Security Documents or the
Notes, or any of them, 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 Indemnified Party's gross negligence or willful misconduct, provided
further, that IT IS THE INTENTION OF THE BANKS TO INDEMNIFY EACH
INDEMNIFIED PARTY FROM AND AGAINST THE CONSEQUENCES OF ITS OWN
NEGLIGENCE. 
Without limiting the generality of the foregoing, each Bank agrees to
reimburse each Indemnified Party promptly upon demand for its Ratable
Share of any out-of-pocket expenses (including counsel fees) incurred by
such Indemnified Party in connection with the preparation, execution,
administration or enforcement of, or the preservation of any rights
hereunder or under the Notes or the Security Documents to the extent such
Indemnified Party is not reimbursed by the Company.

          The payment obligations and indemnities contained in this
Section 11.02 shall survive the payment or sale or transfer of the Notes,
and the termination of this Agreement (i) with respect to all events,
facts, conditions or other circumstances occurring or existing prior to
such sale, transfer or termination, and (ii) with respect to all
liabilities, obligations, losses, damages, penalties, claims, actions,
suits, costs, charges, expenses and disbursements, whenever the same shall
be imposed, incurred or asserted (whether before or after such sale,
transfer, resignation, removal or termination), arising out of the events,
facts, conditions or other circumstances referred to in the first
paragraph of this Section 11.02.  The aforesaid payment obligations and
indemnities are made expressly for the benefit of, and shall be
enforceable by, any Indemnified Party.

     11.03     LIABILITY OF AGENT.  NEITHER THE AGENT NOR ANY OTHER
INDEMNIFIED PARTY SHALL BE LIABLE FOR ANY ACTION TAKEN OR OMITTED
BY IT OR
THEM HEREUNDER, OR IN CONNECTION HEREWITH, (i) with the consent or at the
request of the Banks, or (ii) in the absence of its or their own gross
negligence or willful misconduct.  Without limitation of the generality of
the foregoing, the Agent:  (i) may treat the payee of any Note as the
holder thereof until the Agent receives written notice of the assignment
or transfer thereof signed by such payee and in form satisfactory to the
Agent; (ii) may consult with legal counsel (including counsel for the
Company), independent public accountants and other experts selected by it
and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel,
accountants or experts; (iii) makes no warranty or representation to any
Bank and shall not be responsible to any Bank for any statements,
warranties or representations made in or in connection with this
Agreement, any Security Document or any Note; (iv) shall not have any duty
to ascertain or to inquire as to the performance or observance or any of
the terms, covenants or conditions of this Agreement, the Security
Documents or any Note, or to inspect the property (including the books and
records) of the Company or any Subsidiary; (v) shall not be deemed to have
notice of any Default or Event of Default absent actual knowledge thereof
by a Responsible Officer of the Agent; (vi) shall not be responsible to
any Bank for the due execution, legality, validity, enforceability or
genuineness of this Agreement, any Security Document or any Note, or any
other instrument or document furnished pursuant thereto; and (vii) shall
incur no liability under or in respect of the Agreement, any Security
Document or any Note by acting upon any notice or consent (whether oral or
written and whether by telephone, telegram, cable, telex or facsimile),
certificate or other instrument or writing (which may be by telegram,
cable, telex or facsimile) believed by it to be genuine and communicated,
signed or sent by the proper person or persons.

     11.04     Independent Credit Decision.  Each Bank agrees that it has
relied solely upon its independent review of the financial statements of
the Company and all other representations and warranties made by the
Company herein or otherwise in making the credit decisions preliminary to
entering into this Agreement and agrees that it will continue to rely
solely upon its independent review of the facts and circumstances of the
Company in making future decisions with respect to this Agreement and the
Borrowings.  Each Bank agrees that it has not relied and will not rely
upon the Agent or any other Bank respecting the ability of the Company to
perform its obligations pursuant to this Agreement, the Notes or any
Security Document.

     11.05     Agent and Affiliates; Multiple Capacities. With respect to its
Commitment, the Loans made by it and the Notes payable to it, NationsBank
shall have the same rights and powers under this Agreement, the Security
Documents and the Notes as any other Bank and may exercise the same as
though it were not the Agent; and the term "Bank" or "Banks" shall, unless
otherwise expressly indicated, include NationsBank in its individual
capacity.  NationsBank 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
or entity who may do business with or own securities of any of them or of
their subsidiaries, all as if NationsBank were not the Agent and without
any duty to account therefor to the Banks.  No exercise or failure to
exercise by NationsBank of any of its discretionary powers, rights or
remedies in one capacity shall constitute, or be deemed to constitute, a
breach of any duty of loyalty, fiduciary duty or other duty which
NationsBank has, or may have, in any other capacity.  If at any time any
other Bank shall serve as Agent, the foregoing provisions of this Section
11.05 shall apply to such Bank mutatis mutandis.

     11.06     Successor Agent.  The Agent or any successor or successors
hereunder may at any time, by giving 30 days' prior written notice to the
Company and the Banks, resign and be discharged of the responsibilities
under this Agreement, the Security Documents and the Notes, such
resignation to become effective upon the earlier of (i) 30 days from the
date of such notice or (ii) the appointment of a successor agent, and the
approval of such successor agent by the Majority Banks and the Company
(which consent of the Company will not be unreasonably withheld).  The
Agent may be removed at any time and a successor agent appointed, with the
consent of the Company (which consent shall not be unreasonably withheld),
by the affirmative vote of all of the Banks (other than the Agent);
provided that the Agent so removed shall be entitled to its fees and
expenses to the date of removal.  If no successor agent shall be appointed
and accepted within 30 days from the date of the giving of the aforesaid
notice of resignation or within 30 days from the date of such removal, the
Bank that is an original party to this Agreement (excluding the Agent that
has resigned or been removed) having the largest Ratable Share shall
become the Agent.  Any such successor agent shall immediately and without
further act be superseded by any successor agent appointed by the Banks as
above provided.  Upon the acceptance of any appointment as Agent under
this Agreement by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Agent.  After any retiring Agent's resignation or
removal as Agent under this Agreement, the Security Documents and the
Notes, the provisions of this Article 11 shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Agent under
this Agreement, the Security Documents and the Notes.

12.  MISCELLANEOUS.

     12.01     No Waiver; Remedies.  No failure or delay on the part of the
Agent or any Bank in exercising any power  or right hereunder or under the
Notes or any Security Document shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any
other right or power.  The remedies herein are cumulative and not
exclusive of any remedies provided by law.

     12.02     Amendments, Etc.  Except for amendments to the Security
Documents to effect the addition or release of certain Collateral pursuant
to Sections 9.02, 9.03, or 9.05, no modification or waiver of any
provision of this Agreement, any of the Security Documents or the Notes
and no consent to the departure by the Company therefrom shall in any
event be effective unless the same shall be in writing and signed by the
Majority Banks, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given; provided,
however, that no amendment, waiver or consent shall, unless in writing and
signed by the Agent in addition to the Majority Banks, affect the rights
or duties of the Agent hereunder or under any Security Document.  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.

     12.03     Duty With Respect to Collateral.  The duty of the Agent and
any Bank with respect to the Collateral shall be solely to use reasonable
care in the custody and preservation of Collateral in its possession, and
neither the Agent nor any Bank shall be required to take any steps to
preserve rights against prior parties.

     12.04     Performance of Company's Covenants.  If the Company shall fail
to perform or cause to be performed any of the covenants contained in
Subsections 7.06(b)-(h), 7.09, 7.10 and 7.11, any Bank may, but shall be
under no obligation to, advance sums to perform the same on its behalf;
and sums so advanced by such Bank shall be repaid by the Company on demand
and shall bear interest at the rate of the lesser of the Highest Lawful
Rate or the Prime Rate plus 3% per annum until paid, and shall be secured
hereby, having the benefit of the Security Interest.  No such advance
shall be deemed to relieve the Company from any default under this
Agreement.

     12.05     INDEMNITIES.  Any provision hereof to the contrary
notwithstanding, and whether or not the transactions contemplated by this
Agreement shall be consummated:

          (a)  The Company agrees to pay on demand (i) all reasonable
costs and expenses of the Agent and the Banks paid to third parties in
connection with the preparation, execution, delivery and administration of
this Agreement, the Notes and the Security Documents, and also in
connection with any future amendment or supplement to or waiver or release
with respect to (whether or not given) any of the foregoing (including,
without limitation, the reasonable fees and out-of-pocket expenses of
Baker & Botts, L.L.P., special counsel for the Agent and the Banks, and
Liskow & Lewis, special Louisiana counsel for the Agent and the Banks),
and (ii) all reasonable costs and expenses of the Agent and the Banks
(including reasonable counsel fees and expenses), if any, in connection
with the enforcement of, and preservation of any rights under this
Agreement, the Notes and the Security Documents.

          (b)  THE COMPANY HEREBY ASSUMES LIABILITY FOR, AND AGREES TO
INDEMNIFY, PROTECT, SAVE AND KEEP HARMLESS the Agent and each Bank and
their respective successors and assigns and any of their respective
officers, directors, employees, attorneys and agents, and any of them
(hereinafter for purposes hereof called an "Indemnified Bank Party"), from
and against, any and all liabilities, obligations, losses, damages,
penalties, claims, causes of action, suits, demands, judgments, costs,
charges, expenses and disbursements (including legal fees and expenses),
of whatsoever kind and nature (hereinafter for the purposes hereof
collectively called "Expenses"), imposed on, asserted against or incurred
or suffered by any Indemnified Bank Party and in any way relating to or
arising out of this Agreement, any of the Security Documents or the
construction, manufacture, installation, purchase, acceptance,
non-acceptance, rejection, ownership, delivery, non-delivery, possession,
use, occupancy, transportation, operation, insurance, condition, safety,
return, sale, exchange or other disposition of or in respect of the
Collateral or any portion thereof or interest therein, including latent
and other defects, whether or not discoverable by the Company or any
Indemnified Bank Party, any claim for patent, trademark or copyright
infringement, any claim arising under the strict liability doctrine in
tort or any claim arising from (a) injury to persons or property growing
out of or in connection with the ownership or use of the Collateral, or
any portion thereof or interest therein, or resulting from the condition
or safety thereof or (b) violation or breach by the Company of any
representation, warranty, covenant, agreement or condition contained in
this Agreement or any of the Security Documents or of conditions,
agreements, laws, regulations, requirements and rules affecting or
relating to the Collateral, or any portion thereof or interest therein;
provided, however, that the Company shall not be required to indemnify any
Indemnified Bank Party against Expenses incurred by an Indemnified Bank
Party attributable to its gross negligence or willful misconduct;
provided, further, THAT IT IS THE INTENT OF THE PARTIES HERETO THAT THE
COMPANY INDEMNIFY EACH INDEMNIFIED BANK PARTY AGAINST EXPENSES
INCURRED BY
AN INDEMNIFIED BANK PARTY ATTRIBUTABLE TO THE CONSEQUENCES OF ITS
OWN
NEGLIGENCE, WHETHER SOLE, CONCURRENT, CONTRIBUTORY OR OTHERWISE. 
If the
Company shall have knowledge of any Expense hereby indemnified against, it
will give prompt written notice thereof to every Indemnified Bank Party
concerned.  All amounts payable by the Company under this Subsection
12.05(b) shall be paid directly to the Indemnified Bank Party or Parties
entitled to indemnification.  The Company shall be obligated under this
Subsection 12.05(b) as primary obligor whether or not any Indemnified Bank
Party shall also be indemnified with respect to the same matter under any
other agreement by any other person, and any Indemnified Bank Party
seeking to enforce the indemnification by the Company may proceed directly
against the Company under this Subsection 12.05(b) without first resorting
to any such other rights of indemnification.  If any action, suit or
proceeding shall be brought against any Indemnified Bank Party in
connection with any claim indemnified against under this Subsection
12.05(b), the Company may (and, upon such Indemnified Bank Party's
request, will), at the Company's own cost and expense, resist and defend
such action, suit or proceeding, or cause the same to be resisted and
defended, by counsel selected by the Company and approved by such
Indemnified Bank Party, and, in the event of any failure by the Company to
do so, the Company will pay all costs and expenses (including legal fees
and expenses) incurred by such Indemnified Bank Party in connection with
such action, suit or proceeding.  In the event that the Company shall be
required to make any payment under this Subsection 12.05(b), the amount
payable (and which the Company hereby covenants to pay) shall be an amount
which, after deduction of all taxes required to be paid by the particular
Indemnified Bank Party in respect of the receipt thereof under the laws of
the United States of America or of any political subdivision thereof
(after giving credit for any savings in respect of any such taxes by
reason of deductions, credits or allowances in respect of the payment of
the expense indemnified against, and of any such taxes), shall be equal to
the amount of such payment.  Upon the payment in full by the Company of
any indemnities under this Subsection 12.05(b), the Company shall be
subrogated to any right of such Indemnified Bank Party in respect of the
matter against which indemnity shall have been given.  Thereafter, and so
long as no Default or Event of Default has occurred and is continuing, any
payment received by any Indemnified Bank Party from any person (except the
Company) as a result of any matter with respect to which such Indemnified
Bank Party has been indemnified by the Company under this Subsection
12.05(b) shall be paid over to the Company to the extent necessary to
reimburse the Company for indemnification payments previously made.

          Without limiting the generality of the foregoing, THE COMPANY
HEREBY ASSUMES LIABILITY FOR, AND AGREES TO INDEMNIFY, PROTECT, SAVE
AND
KEEP HARMLESS each Indemnified Bank Party from and against, any and all
liabilities, obligations, losses, damages, penalties, claims, causes of
action, suits, demands, judgments, costs, charges, expenses and
disbursements (including legal fees and expenses), which any of the
Indemnified Bank Parties may sustain or incur by reason of or arising out
of any and all claims or proceedings (whether brought by a private party,
governmental authority, or otherwise) for bodily injury, property damage,
abatement, remediation, environmental damage, or impairment or any other
injury or damage resulting from or relating to any Hazardous Materials
located upon, migrating into, from, or through or otherwise relating to
any property of the Company or any Subsidiary (whether or not the release
of such Hazardous Materials was caused by the Company, any Subsidiary, a
tenant, or subtenant of the Company or any Subsidiary, a prior owner, a
tenant or subtenant of any prior owner or any other party and whether or
not the alleged liability is attributable to the handling, storage,
generation, transportation, or disposal of any Hazardous Materials or the
mere presence of any Hazardous Materials on such property; provided that
the Company shall not be liable to the Indemnified Bank Parties where the
release of such Hazardous Materials occurs at any time after which the
Company or any Subsidiary has ceased to own such property), which any
Indemnified Bank Party may incur due to the making of Loans or the
Commitments hereunder, the exercise of any of its rights under this
Agreement, the Notes, the Security Documents, or otherwise, provided that
no Indemnified Bank Party shall be entitled to the benefits of this
paragraph to the extent its own gross negligence or willful misconduct
contributed to its loss, provided, further, THAT IT IS THE INTENT OF THE
PARTIES HERETO THAT THE COMPANY INDEMNIFY EACH INDEMNIFIED BANK
PARTY FROM
AND AGAINST THE CONSEQUENCES OF SUCH INDEMNIFIED BANK PARTY'S OWN
NEGLIGENCE, WHETHER SOLE, CONCURRENT, CONTRIBUTORY OR OTHERWISE. 
If any
action, suit or proceeding shall be brought against any Indemnified Bank
Party in connection with any claim indemnified against under this
paragraph of this Subsection 12.05(b), the Company may (and, upon such
Indemnified Bank Party's request, will), at the Company's own cost and
expense, resist and defend such action, suit or proceeding, or cause the
same to be resisted and defended, by counsel selected by the Company and
approved by such Indemnified Bank Party, and, in the event of any failure
by the Company to do so, the Company will pay all costs and expenses
(including legal fees and expenses) incurred by such Indemnified Bank
Party in connection with such action, suit or proceeding.  Upon the
payment in full by the Company of any indemnities under this Subsection
12.05(b), the Company shall be subrogated to any right of such Indemnified
Bank Party in respect of the matter against which indemnity shall have
been given.  Thereafter, and so long as no Default or Event of Default has
occurred and is continuing, any payment received by any Indemnified Bank
Party from any person (except the Company) as a result of any matter with
respect to which such Indemnified Bank Party has been indemnified by the
Company under this Subsection 12.05(b) shall be paid over to the Company
to the extent necessary to reimburse the Company for indemnification
payments previously made.

          (c)  The payment obligations and indemnities contained in
this Section 12.05 shall survive the payment or sale or transfer of the
Notes, and the termination of this Agreement  with respect to all events,
facts, conditions or other circumstances occurring or existing prior to
such sale, transfer or termination, and  with respect to all liabilities,
obligations, losses, damages, penalties, claims, actions, suits, costs,
charges, expenses and disbursements, whenever the same shall be imposed,
incurred or asserted (whether before or after such sale, transfer,
resignation, removal or termination), arising out of the events, facts,
conditions or other circumstances referred to in clause (i) of this
Subsection 12.05(c).  The aforesaid payment obligations and indemnities
are made expressly for the benefit of, and shall be enforceable by, any
Indemnified Bank Party.

construed to require or permit the payment or collection of interest at a
rate that exceeds the Highest Lawful Rate (and, to the extent that the
Highest Lawful Rate is at any time determined by Texas law, such rate
shall be the "indicated rate ceiling" described in Section (a)(1) of
Article 1.04 of Chapter 1, Subtitle 1, Title 79, of the Revised Civil
Statutes of Texas, 1925, as amended; provided, however, to the extent
permitted by such Article, the Banks from time to time by notice through
the Agent to the Company may revise the aforesaid election of such
interest rate ceiling as such ceiling affects the then current or future
balances of the Borrowings outstanding under the Notes).  Accordingly, if
the maturity of the Notes is accelerated for any reason, or in the event
of voluntary prepayment of all or any portion of the Notes by the Company,
or in any other event, earned interest for any Bank on each Borrowing may
never exceed the Highest Lawful Rate, computed from the Borrowing Date of
each such Borrowing until payment, and any unearned interest otherwise
payable under any Note which is in excess of the Highest Lawful Rate shall
be canceled automatically as of the date of such acceleration or
prepayment or other such event and (if theretofore paid) shall, at the
option of the holder of such Note, be either refunded to the Company or
credited on the principal of such Note.  In determining whether or not the
interest paid or payable, under any specific contingency, exceeds the
Highest Lawful Rate, the Company and the Banks shall, to the maximum
extent permitted by applicable law, (a) characterize any nonprincipal
payment as an expense, fee or premium rather than as interest, and (b)
amortize, prorate, allocate and spread, in equal parts during the period
of the full stated term of the borrowing in question, all interest at any
time contracted for, charged, received or reserved in connection with such
Borrowing.

     12.09     Survival of Representations and Warranties.  All
representations, warranties and covenants contained herein or made in
writing by the Company in connection herewith shall survive the execution
and delivery of this Agreement and of the Notes, and will bind and inure
to the benefit of the respective successors and assigns of the parties
hereto, whether so expressed or not, provided that the undertaking of the
Banks to make the Loans to the Company shall not inure to the benefit of
any successor or assign of the Company.

     12.10     Severability.  Should any clause, sentence, paragraph,
subsection 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.

     12.11     Descriptive Headings.  The section headings in this Agreement
have been inserted for convenience only and shall be given no substantive
meaning or significance whatever in construing the terms and provisions of
this Agreement.

     12.12     Counterparts.  This Agreement may be executed in several
counterparts, and by the parties hereto on separate counterparts.  When
counterparts executed by all the parties shall have been delivered to the
Agent, this Agreement shall become effective, and at such time the Agent
shall notify the Company and each Bank.  Each counterpart, when so
executed and delivered, shall constitute an original instrument, and all
such separate counterparts shall constitute but one and the same
instrument.

     12.13     GOVERNING LAW.  THIS AGREEMENT AND THE NOTES SHALL BE
INTERPRETED AND GOVERNED BY, AND THE RIGHTS, OBLIGATIONS AND
LIABILITIES
OF THE PARTIES HERETO AND THERETO SHALL BE DETERMINED IN
ACCORDANCE WITH,
THE LAWS OF THE STATE OF TEXAS AND APPLICABLE FEDERAL LAW.  Without
limitation of the foregoing, nothing in this Agreement or in the Notes
shall be deemed to constitute a waiver of any rights which any Bank may
have under applicable federal legislation relating to the rate of interest
which such Bank may contract for, take, reserve, receive or charge in
respect of any borrowing.  Chapter 15, Subtitle 3, Title 79, of the
Revised Civil Statutes of Texas, 1925, as amended (relating to revolving
loan and revolving triparty accounts), shall not apply to this Agreement
or the Notes hereunder or the transactions contemplated hereby.

          THIS WRITTEN "LOAN AGREEMENT" (AS DEFINED IN SECTION 26.02 OF
THE TEXAS BUSINESS AND COMMERCE CODE, AS IN EFFECT ON THE EFFECTIVE
DATE
AND AS THE SAME MAY THEREAFTER BE AMENDED AT ANY TIME AND FROM
TIME TO
TIME), TOGETHER WITH THE NOTES AND THE SECURITY DOCUMENTS,
REPRESENTS THE
FINAL AGREEMENT BETWEEN THE COMPANY, THE BANKS AND THE AGENT AND
MAY NOT
BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL
AGREEMENTS OF SAID PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS
BETWEEN SAID PARTIES.

Restricted Stock issuable under Section 2.1 shall not exceed the limit
specified in the first paragraph of Section 2.1.

     2.3  If the Award Recipient's employment with the Company should

such shares of Restricted Stock.

     4.2  Upon the lapse of restrictions on shares of Restricted Stock
issued to the Award Recipient in accordance with the provisions of Section
2.1, PHI shall cause a stock certificate without a restrictive legend
representing such shares of Restricted Stock to be issued in the name of the
Award Recipient or his nominee within 30 days after the end of the

Recipient is free to hold or dispose of the shares of Common Stock
represented by such certificate subject to applicable securities laws.

                             Withholding Taxes

     At any time that an Award Recipient is required to pay to the Company
an amount required to be withheld under the applicable income tax laws in
connection with the lapse of restrictions on shares of Restricted Stock, the
Award Recipient may, subject to the approval of the Committee, satisfy this
obligation in whole or in part by electing that the Company withhold shares
of Common Stock having a value equal to the amount required to be withheld
in accordance with the terms of the Plan currently in effect or as it may
be amended.

                                    7.

                           Additional Conditions

     Anything in this Agreement to the contrary notwithstanding, if at any
time PHI further determines, in its sole discretion, that the listing,
registration or qualification (or any updating of any document) of the
shares of Common Stock issued or issuable pursuant hereto is necessary on
any securities exchange or under any federal or state securities or blue sky
law, or that the consent or approval of any governmental regulatory body is
necessary or desirable as a condition of, or in connection with, the
issuance of shares of Common Stock pursuant hereto, or the removal or any
restrictions imposed on such shares, such shares of Common Stock shall not
be issued, in whole or in part, or the restrictions thereon removed, unless
such listing, registration, qualification, consent or approval shall have
been effected or obtained free of any conditions not acceptable to PHI.

                                    8.

right to continue in the employment of the Company or to interfere in any
way with the right of the Company to terminate the Award Recipient's em-

ployment relationship with the Company at any time.

                   NON-QUALIFIED STOCK OPTION AGREEMENT
                      UNDER THE AMENDED AND RESTATED
                        PETROLEUM HELICOPTERS, INC.
               1995 INCENTIVE COMPENSATION PLAN, AS AMENDED
  
  
     THIS AGREEMENT is entered into as of July 30, 1996, by and between
  Petroleum Helicopters, Inc., a Louisiana corporation ("PHI"), and Carroll
  W. Suggs (the "Optionee").
  
     WHEREAS, under the Amended and Restated Petroleum Helicopters, Inc.
  1995 Incentive Compensation Plan, as amended (the "Plan"), the Compensation
  Committee of the PHI Board of Directors (the "Committee") may, among other
  things, award options to purchase shares of the non-voting common stock,
  $.10 par value per share, of PHI (the "Common Stock") to a key employee of
  PHI or one of its subsidiaries (collectively, the "Company"); and 
  
     WHEREAS, pursuant to the Plan, on July 30, 1996, the Committee awarded
  an option to purchase Common Stock to the Optionee.
  
     NOW, THEREFORE, in consideration of the premises, it is agreed as
  follows:
  
                                  1.
  
                            Grant of Option
  
     1.1  PHI hereby grants to the Optionee effective July 30, 1996 (the
  "Date of Grant") the right, privilege and option to purchase 23,200 shares
  of Common Stock (the "Option") at an exercise price of $14.875 per share
  (the "Exercise Price").  The Option shall vest, become exercisable and
  expire as provided in Sections 2 and 3 below.
  
     1.2  The Option is a non-qualified stock option and shall not be
  treated as an incentive stock option under Section 422 of the Internal
  Revenue Code of 1986, as amended.
  
                                  2.
  
                           Vesting of Option
  
     2.1  Effective July 31, 1997, the Compensation Committee of the Board
  of Directors of PHI (the "Committee") shall make a determination as to the
  portion of the Option that is vested as follows:
  
          (a)  Company Performance Goals
  
               (1)  If the Company's consolidated earnings before
       income taxes for the fiscal year ending April 30, 1997, as adjusted
       by the Committee for extraordinary items ("Actual Operating Income"),
       equals the consolidated earnings before income taxes reflected in the
       Company's annual budget for the fiscal year ending April 30, 1997
       ("Budgeted Operating Income"), the Option shall vest with respect to
       16,000 of the shares covered thereby.
  
               (2)  If Actual Operating Income exceeds Budgeted
       Operating Income, the Option shall vest with respect to an additional
       160 shares for each 1% by which Actual Operating Income exceeds
       Budgeted Operating Income, up to a maximum of 3,200 additional
       shares.
  
               (3)  If Actual Operating Income is less than Budgeted
       Operating Income, but is between 90% and 100% of Budgeted Operating
       Income, then the Option shall vest with respect to 16,000 shares,
       less 320 shares for each 1% or fraction of 1% by which Actual
       Operating Income is less than Budgeted Operating Income.
  
               (4)  If Actual Operating Income is less than 90% of
       Budgeted Operating Income, no portion of the Option shall vest based
       upon Company performance.
  
          (b)  Individual Performance
  
     The Option may vest with respect to up to an additional 4,000 shares
  in the discretion of the Compensation Committee based on an evaluation of
  the Optionee's performance for the year.
  
     2.2  All unvested Options or portions thereof shall be forfeited.
  
                                  3.
  
                           Time of Exercise
  
     3.1  Subject to the provisions of the Plan and Section 2 hereof, the
  Optionee shall be entitled to exercise the vested portion of the Option with
  respect to 50% of the shares beginning July 31, 1997 and with respect to the
  remaining 50% of the shares beginning July 31, 1998.
  
     3.2  The Option shall expire and may not be exercised later than ten
  years following the Date of Grant.
  
     3.3  Notwithstanding the foregoing, the Option shall become
  accelerated and immediately exercisable to the extent vested if (a.) the
  Optionee dies while she is employed by the Company, (b.) the Optionee
  becomes disabled within the meaning of Section 22(e)(3) of the Code
  ("Disability") while she is employed by the Company, (c.) the Optionee
  retires from employment with the Company on or after attaining the age of
  65 or is granted early retirement by a vote of the Board of Directors
  ("Retirement") or (d.) pursuant to the provisions of the Plan.
  
                                  4.
  
                   Conditions for Exercise of Option
  
     During the Optionee's lifetime, the Option may be exercised only by
  her or by her guardian or legal representative.  The Option must be exer-
  
  cised while the Optionee is employed by the Company, or, to the extent
  exercisable at the time of termination of employment, within 190 days of the
  date on which she ceases to be an employee, except that (a.) if she ceases
  to be an employee because of Retirement or Disability, the Option may be
  exercised within three years from the date on which she ceases to be an
  employee, (b.) if the Optionee's employment is terminated for cause, the
  unexercised portion of the Option is immediately terminated, and (c.) in the
  event of the Optionee's death, the Option may be exercised by her estate,
  or by the person to whom such right devolves from her by reason of her death
  within two years after the date of her death; provided, however, that no
  Option may be exercised later than 10 years after the Date of Grant.
  
                                  5.
  
                         Additional Conditions
  
     Anything in this Agreement to the contrary notwithstanding, if at any
  time PHI further determines, in its sole discretion, that the listing,
  registration or qualification (or any updating of any such document) of the
  shares of Common Stock issuable pursuant to the exercise of an Option is
  necessary on any securities exchange or under any federal or state
  securities or blue sky law, or that the consent or approval of any
  governmental regulatory body is necessary or desirable as a condition of,
  or in connection with the issuance of shares of Common Stock pursuant
  thereto, or the removal of any restrictions imposed on such shares, such
  shares of Common Stock shall not be issued, in whole or in part, unless such
  listing, registration, qualification, consent or approval shall have been
  effected or obtained free of any conditions not acceptable to PHI.
  
                                  6.
  
                  No Contract of Employment Intended
  
     Nothing in this Agreement shall confer upon the Optionee any right to
  continue in the employ of the Company or to interfere in any way with the
  right of PHI to terminate the Optionee's employment relationship with the
  Company at any time.
  
                                  7.
  
                                 Taxes
  
     The Company may make such provisions as it may deem appropriate for
  the withholding of any federal, state and local taxes that it determines are
  required to be withheld on the exercise of the Option.
  
                                  8.
  
                            Binding Effect
  
     This Agreement shall inure to the benefit of and be binding upon the
  parties hereto and their respective heirs, executors, administrators and
  successors.
  
                                  9.
  
                        Inconsistent Provisions
  
     The Option granted hereby is subject to the provisions of the Plan. 
  If any provision of this Agreement conflicts with a provision of the Plan,
  the Plan provision shall control.
  
                                  10.
  
                        Adjustments to Options
  
     Appropriate adjustments shall be made to the number and class of
  shares of Common Stock subject to the Option and to the Exercise Price in
  certain situations described in Section 12.6 of the Plan.
  
                                  11.
  
                         Termination of Option
  
     The Committee, in its sole discretion, may terminate the Option. 
  However, no termination may adversely affect the rights of the Optionee to
  the extent that the Option is currently vested on the date of such
  termination.
  
     IN WITNESS WHEREOF the parties hereto have caused this Agreement to
  be executed as of the day and year first above written.
