   12

Loan only to refinance the Debtor's purchase of the Engine.

        2.5 Increased Costs. If any change in any law, regulation or treaty, or
in the interpretation or administration thereof, or compliance by the Lender
with any request or directive (whether or not having the force of law) of any
authority charged with the interpretation or administration thereof, shall in
the reasonable determination of the Lender:

        (a) subject the Lender to any tax, levy or other governmental charge
with respect to the Loan or its obligation to make or maintain the Loan or
change the basis of taxation of payments by the Debtor to the Lender in respect
of the Loan (other than any tax on or measured by the overall net income of the
Lender); or

        (b) impose, modify or hold applicable any reserve, special deposit or
similar requirement against assets of, deposits or other liabilities of or for
the account of, or loans or commitments by, the Lender with respect to the Loan
(including without limitation any reserves against "Eurocurrency Liabilities"
under Regulation D of the Board of Governors of the Federal Reserve System); or

         (c) impose on the Lender any other condition with respect to the Loan
or its obligation to make and maintain the Loan; and the result of any of the
foregoing is to increase the cost to the Lender of making or maintaining such
Loan or to reduce the amount of any sum received or receivable by the Lender
under this Agreement or the Note issued to the Lender, then the Debtor shall pay
to the affected Lender on demand from time to time such additional amounts as
may be necessary to reimburse the Lender for such increased cost or to
compensate the Lender for such reduced amount; provided, however, that upon the
Debtor's payment of such increased cost or compensation to the Lender, the
Debtor shall have the option to prepay the Note in full at the time of its
payment of any such increased cost or compensation with no prepayment penalty at
such time only. A certificate, calculating in reasonable detail the amount of
such increased cost or reduced amount, shall be submitted to the Debtor by any
affected Lender, and shall, absent manifest error, be final, conclusive and
binding for all purposes.

        2.6 Capital Adequacy. If any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any governmental agency or
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Lender with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, in 



                                       12
   13

the Lender's reasaonable determination (which determination shall be conclusive
and binding) has the effect of increasing the amount of capital required to be
maintained by the Lender or reducing the rate of return on capital as a
consequence of its agreement to make, or its making of, the Loan pursuant to
this Agreement to a level below that which the Lender could have achieved but
for such adoption, change or compliance (taking into consideration policies with
respect to capital adequacy) by an amount reasonably deemed by the Lender to be
material, then, upon demand by the Lender, the Debtor shall pay to the Lender,
from time to time as specified by the Lender, such additional amounts which
shall be sufficient to compensate the Lender for the cost of such additional
capital or reduced rate of return; provided, however, that upon the Debtor's
payment of such additional amounts or compensation to the Lender, the Debtor
shall have the option to prepay the Note in full at the time of its payment of
any such additional amounts or compensation with no prepayment penalty at such
time only. A certificate calculating in reasonable detail the amount of any such
cost or reduced rate of return, submitted to the Debtor by any such affected
Lender, shall, absent manifest error, be final, conclusive and binding for all
purposes.

        2.7 Illegality. In the event that the Lender shall have reasonably
determined that the making or continuation of the Loan is or has become unlawful
or interferes with or prevents compliance by the Lender in good faith with any
applicable law, governmental rule, regulation, guideline or order (whether or
not having the force of law or whether or not failure to comply therewith would
be unlawful), the Lender shall promptly give notice to the Debtor of such
determination. The Debtor shall, on the next Installment Payment Date after
notice of any such determination or earlier if required by law, repay the entire
Loan, together with all interest accrued thereon and all other amounts payable
hereunder and under the Note with no prepayment penalty at such time only.

        2.8 Funding Losses. If the Debtor fails to fulfill the conditions set
forth in Sections 2.5, 2.6, and/or 2.7 of this Agreement by the time specified
for their fulfillment or otherwise fails to borrow the Loan after delivering a
notice with respect thereto, then the Debtor shall pay the Lender the amount of
any losses, costs and expenses reasonably incurred as a consequence thereof,
including any loss of margin or expenses incurred in liquidating or re-employing
deposits or other funds acquired to make such Loan. A certificate, calculating
in reasonable detail the amount of any such losses, costs and expenses,
submitted to the Debtor shall, absent manifest error, be final, conclusive and
binding for all purposes.

        2.9 Method of Payment. The Debtor shall make each payment due under this
Agreement and under the Note to the Lender at its 



                                       13

under this Agreement) any amount due under this Agreement or the Note,
including, without limitation, principal, interest, fees and charges, against
any account of the Debtor with the Lender (other than any payments or amounts
held in the Account which are solely Maintenance Fees or Security Deposits which
payments or amounts shall be disbursed pursuant to the terms of Sections 9.1(b),
9.1(c) and/or 10.13 of this Agreement). Whenever any payment to be made under
this Agreement or under the Note shall be stated to be due on a Saturday, Sunday
or a public holiday, or the equivalent for banks generally under the laws of the

succeeding Business Day, and such extension of time shall be included in the

Without limiting the generality of the foregoing, Debtor shall (or shall cause
the Lessee to) maintain, inspect, service, repair, overhaul and test the Engine,
and furnish all parts, replacements, mechanisms, devices and servicing required
therefor, so that the value, condition and operating efficiency of the Engine

operated by Debtor (or the Debtor shall cause the Lessee to) maintain, use and
operate the Engine, in compliance with any and all statutes, laws, ordinances,
regulations and mandatory standards, letters, circulars, bulletins, instructions
or directives issued by any governmental agency applicable to the maintenance,
use or operation thereof, in compliance with any certificate, license or
registration relating to the Engine issued by any agency, and in a manner that
does not modify or impair any existing warranties on the Engine or any part
thereof. Debtor shall also (or shall cause the Lessee to) operate the Engine
solely in the conduct of its business and/or for commercial purposes, and Debtor
shall not (and shall cause the Lessee not to) operate or permit the Engine to be
operated at any time or in any

   32

geographic area when or where insurance required by the provisions of Section
5.12 hereof shall not be in effect or excluded from coverage, or in any
recognized or threatened area of hostilities unless fully covered to Lender's
satisfaction by hull, war, and political risk insurance, or any area in which
Lender's first lien on the Engine may be jeopardized or not recognized, as
determined in Lender's sole judgment, or in a manner, for any time period, such
that, any third party shall be deemed to have "operational control" of the
Engine, except for the Lessee pursuant to the terms of the Lease.
Notwithstanding anything contained in this Section 5.11(b) to the contrary, so
long as the Debtor shall (or cause the Lessee to) use, operate, maintain,
inspect, service, repair, overhaul and test the Engine (and maintain and keep
any Records) at a level which fully satisfies in all respects the terms and
conditions of the Lease, the Debtor shall be deemed to have complied in all
respects to the terms and conditions of this Section 5.11(b).

        (c) Identification. If requested by Lender in writing, Debtor shall, at
its own cost and expense (or the Debtor shall cause the Lessee, at the Lessee's
own cost and expense to), attach to the Engine a data plate satisfactory to
Lender disclosing Lender's security interest in the Engine.

        (d) Replacement Parts. Debtor, at its own cost and expense, will
promptly (or will cause the Lessee to promptly) replace all Parts which may from
time to time become worn out, lost, stolen, taken, destroyed, seized,
confiscated, requisitioned, damaged beyond repair or permanently rendered or
declared unfit for use for any reason whatsoever (such substituted Parts
hereinafter called "Replacement Parts"). In addition, in the ordinary course of
maintenance, service, repair, overhaul or testing, Debtor may, at its own cost
and expense, (or may cause the Lessee to promptly) remove serviceable Parts,
provided that Debtor shall, at its own cost and expense (or Debtor shall cause
the Lessee, at the Lessee's own cost and expense to), replace such serviceable
Parts as promptly as practicable. All Replacement Parts (i) shall be owned by
Debtor or Lessee free and clear of all Liens (other than the Lien of the Lender
hereunder), (ii) shall be in an airworthy condition and of at least equivalent
model and modification status and/or service bulletin accomplishment status,
shall be fully interchangeable as to form, fit and function and shall be in a
good operating condition as, and shall have a value and utility at least equal
to, the Parts replaced assuming such replaced Parts were in the condition and
repair required to be maintained by the terms hereof, (iii) shall have a current
"serviceable tag" of the manufacturer or maintenance facility providing such
items to Debtor or Lessee, indicating that such Parts are new, serviceable or
overhauled, (iv) if serviceable, shall have all maintenance records from the
last overhaul thereof and the maintenance history since the last overhaul
thereof, (v) if overhauled, have all overhaul records, and (vi) if a life
limited Part, have continuous 



                                       32
   33

records since the date of manufacture or the date of the last overhaul. All
Parts at any time removed from the Engine shall remain part of the Collateral,
no matter where located, until such time as such Parts shall be replaced by
Parts which have been incorporated or installed in or attached to the Engine and
which meet the requirements for Replacement Parts specified above. Without
limiting the generality of any term of this Agreement, immediately upon any
Replacement Part becoming incorporated or installed in or attached to the Engine
as above provided, without further act, such Replacement Part shall become
subject to this Agreement including, without limitation, the lien and security
interest of this Agreement, and shall be deemed part of the Collateral and shall
be deemed part of the Engine, as the case may be, for all purposes hereof to the
same extent as the Parts originally incorporated or installed in or attached to
the Engine, and the Lender's lien and security interest with respect to the Part
being replaced by the Replacement Part shall automatically thereafter be deemed
to be released and shall no longer be subject to the terms of this Agreement.
Notwithstanding anything contained in this Section 5.11(d) to the contrary, so
long as the Debtor shall (or cause the Lessee to) use, operate, maintain,
inspect, service, repair, overhaul and test the Engine and replace any Parts
(and maintain and keep any Records) at a level which fully satisfies in all
respects the terms and conditions of the Lease, the Debtor shall be deemed to
have complied in all respects to the terms and conditions of this Section
5.11(d).

        (e) Additions; Modifications. Debtor (or the Lessee) shall be entitled
from time to time during the term of this Agreement to, at Debtor's or Lessee's
sole cost and expense, make such alterations, modifications, additions to or
removals from any Engine or Engine as may be reasonable in the proper conduct by
Debtor (or the Lessee, as applicable) of its business; provided, that in no
event shall any such alteration, modification, addition or removal (i) impair
the originally intended function or use of the Engine or diminish the use,
condition or value of the same, assuming the Engine was in the condition and
repair then required to be maintained by the terms hereof, and/or (ii) as to any
Additional Parts (as such term is defined below), the removal of any such
Additional Parts can be readily removed without causing material damage to the
Engine. All Parts incorporated or installed in or attached to the Engine as the
result of such alteration, modification or addition shall be collectively
referred to as the "Additional Parts". Debtor shall (or shall cause the Lessee
to) repair all damage to the Engine resulting from any installation and/or
removal of any Additional Parts so as to restore the Engine to its condition
prior to installation, normal wear and tear excepted assuming the Engine was in
the condition and repair then required to be maintained by the terms hereof. Any
alterations or modifications with respect to the Engine that may at any time
during the term of this Agreement be required to comply with applicable law or
any governmental rule or regulation shall be 



                                       33
   34

made at the sole cost and expense of Debtor or Lessee, as applicable. Without
limiting the generality of any term of this Agreement, immediately upon any
Additional Parts becoming incorporated or installed in or attached to the Engine
as above provided, without further act, such Additional Parts shall become
subject to this Agreement including, without limitation, the lien and security
interest of this Agreement, and shall be deemed part of the Collateral and shall
be deemed part of the Engine, as the case may be, for all purposes hereof to the
same extent as the Parts originally incorporated or installed in or attached to
the Engine; provided, that if such Additional Part was in addition to, and not a
replacement of or substitution for, any Part incorporated or installed in or
attached or added to the Engine on the date the Engine became subject to the
terms of this Agreement (a "Debtor Additional Part"), Debtor may (or may cause
the Lessee to) at any time remove such Debtor Additional Part from the Engine so
long as the removal of such Debtor Additional Part (i) does not impair the
originally intended function or use of the Engine or diminish the use, condition
or value of the same, assuming the Engine was in the condition and repair then
required to be maintained by the terms hereof, and/or (ii) can be readily
removed without causing material damage to the Engine, and upon removal of such
Debtor Additional Part, Lender's lien and security interest with respect to such
Debtor Additional Part shall automatically be deemed to be released and shall no
longer be subject to the terms of this Agreement. Notwithstanding anything
contained in this Section 5.11(e) to the contrary, so long as the Debtor shall
(or cause the Lessee to) use, operate, maintain, inspect, service, repair,
overhaul and test the Engine and make additions or modifications to the Engine
or any Parts (and maintain and keep any Records) at a level which fully
satisfies in all respects the terms and conditions of the Lease, the Debtor
shall be deemed to have complied in all respects to the terms and conditions of
this Section 5.11(e).

        5.12   Insurance.

        (a) Engine Liability and Property Damage Insurance. Debtor represents
and warrants that it will (or will cause the Lessee to) maintain at all times,
at its own cost and expense (or at the Lessee's own cost and expense), with
insurers of recognized responsibility, (i) comprehensive aircraft and general
public liability insurance against bodily injury and property damage claims in
an amount not less than $300,000,000.00 for each single occurrence and (ii) such
other property damage insurance (exclusive of manufacturer's product liability
insurance) with respect to the Engine as is of the type and in the amounts
usually carried by companies engaged in the same or a similar business as Debtor
(or Lessee), similarly situated with Debtor (or Lessee), and owning or operating
similar aircraft and engines, and which covers risks of the kind customarily
insured against by such 



                                       34
   35

companies.

        (b) Insurance Against Loss or Damage to the Engine. Debtor represents
and warrants that it will (or will cause the Lessee to) maintain in effect at
all times, at its own cost and expense (or at the Lessee's own cost and
expense), with insurers of recognized responsibility, all-risk ground and flight
aircraft hull insurance covering the Engine, provided that such insurance shall
at all times be not less than the greater of (i) the full replacement value of
the Engine as such value is set forth on Exhibit C attached hereto, (ii) the
aggregate unpaid principal amount of the Note or (iii) the amount which would be
paid pursuant to Section 2.3 hereof upon the occurrence of an Event of Loss
(each such amount determined as of each anniversary of the Closing Date for the
next succeeding year throughout the term of this Agreement). Debtor shall (or
shall cause the Lessee to), at its (or the Lessee's) own cost and expense,
additionally maintain in effect with an insurer of recognized responsibility
reasonably satisfactory to Lender, hijacking (air piracy) insurance with respect
to the Engine in a face amount of not less than the greater of (i) the full
replacement value of the Engine as such value is set forth on Exhibit C attached
hereto, (ii) the aggregate unpaid principal amount of the Note or (iii) the
amount which would be paid pursuant to Section 2.3 hereof upon the occurrence of
an Event of Loss (each such amount determined as of each anniversary of the
Closing Date for the next succeeding year throughout the term of this
Agreement), which shall be in full force and effect throughout any geographical
areas at any time traversed by the Engine. Such insurance shall also include
governmental confiscation and expropriation and related insurance, if and to the
extent the same is maintained by Debtor (or Lessee, as applicable) with respect
to other aircraft owned or operated by Debtor (or Lessee, as applicable) on the
same routes as the Engine or where the custom in the United States airline
industry is to carry such insurance with respect to aircraft and engines
operated on the same routes as the Engine.

        (c) Lender as Additional Insured; Notice. Any policies of insurance
carried in accordance with this Section and any policies taken out in
substitution or replacement or any such policies (i) shall be amended to name
Lender as the additional insured as its interests may appear, (ii) with respect
to insurance carried in accordance with paragraph (b) of this Section 5.12
covering the Engine, shall provide that any amount(s) payable thereunder which
exceed $200,000.00 in the aggregate shall be paid directly to Lender as sole
loss payee and not to Lender and Debtor jointly (and, so long as no Event of
Default has occurred, such amounts shall be disbursed by Lender to Debtor or
other appropriate persons for payment of the costs actually incurred with
respect to repairs made to the Engine so as to restore it to the operating
condition required hereunder, or shall be disbursed by Lender as otherwise
required by this Agreement), and that any amount(s) of 



                                       35
   36

less than $200,000.00 in the aggregate shall be paid to Debtor (and such amounts
shall be applied by Debtor to pay the costs of such repairs) provided, however,
that if an Event of Default has occurred, any and all such proceeds or amounts
shall be paid directly to Lender to be applied pursuant to the applicable terms
of this Agreement, (iii) shall provide that if any insurer cancels such
insurance for any reason whatever, or any substantial change is made in any of
the coverage required hereunder, or the same is allowed to lapse for nonpayment
of premium or such insurance coverage is reduced, such cancellation, change,
lapse or reduction shall not be effective as to Lender for thirty (30) days
following receipt by Lender of written notice, and (iv) shall provide that in
respect of the interests of Lender in such policies, the insurance shall not be
invalidated by any action or inaction of Debtor or any other Person (other than
Lender). Each insurance policy and its respective cover amount(s) obtained in
accordance with the requirements set forth in paragraphs (a) and (b) of this
Section 5.12 shall (i) be primary insurance, not subject to any co-insurance
clause and shall be without right of contribution from any other insurance, and
(ii) expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured or loss payee, and shall waive any right of such insurer
to any setoff, counterclaim or other deduction, by attachment or otherwise, in
respect of Lender or Debtor. Debtor shall arrange for appropriate certification
as to the satisfaction of the requirements set forth above in this Section 5.12
to be delivered to Lender not later than the Closing Date.

        (d) Reports, etc. Upon the request of the Lender, Debtor shall furnish
to Lender a report describing in reasonable detail the insurance then carried
and maintained on the Engine and certifying that such insurance complies with
the terms hereof and such other evidence of insurance coverage that the Lender
reasonably requests. In the event Debtor shall fail to maintain insurance as
herein provided, Lender may, at its option, provide such insurance, and Debtor
shall, upon demand, reimburse Lender for the cost thereof, together with
interest at the Late Charge Rate from the date of payment through the date of
reimbursement.

        (e) Agreed Value. Anything herein to the contrary notwithstanding, at
all times while the Engine is subject to this Agreement, the insurance required
by Section 5.12 of this Agreement shall be for an amount on an "agreed value"
basis not less than the greater of (i) the full replacement value of the Engine
as such value is set forth on Exhibit C attached hereto, (ii) the aggregate
unpaid principal amount of the Note or (iii) the amount which would be paid
pursuant to Section 2.3 hereof upon the occurrence of an Event of Loss (each
such amount determined as of each anniversary of the Closing Date for the next
succeeding year throughout the term of this Agreement).

        (e) using its best efforts to remarket, lease or sell the Engine upon
any Lessee Event of Default under the Lease so long as no Event of Default has
occurred under this Agreement (other than any Event of Default based on any
Lessee Event of Default under the Lease), provided, however, that any bona fide
and arm's length lease or sale of the Engine proposed by the Debtor to any
Person that is not an Affiliate shall be subject to the prior written consent of

reports regarding the Engine which are provided by the Lessee to the Debtor
pursuant to the terms of the Lease and copies of any reports or other
information regarding any damage to the Engine.

furnish to Lender from time to time such information relating to the Collateral,
the Debtor or the Guarantor (or their respective Subsidiaries and/or
Affiliates), financial or otherwise, as Lender shall reasonably request;
provided, however, with regard to any additional information concerning the
Engine, the Lender shall be entitled to (i) any additional information
concerning the Engine which the Lessee is required to provide the Debtor (or the

        SECTION 6. SECURITY INTEREST.

        6.1 Grant of Security Interest. As collateral security for the prompt
and complete payment and performance when due of all of the Obligations and in
order to induce Lender to enter into this Agreement and make the Loan to Debtor
in accordance with the terms hereof and to extend other credit from time to time
to Debtor, whether under this Agreement, the Note or otherwise, Debtor hereby
assigns, conveys, mortgages, pledges, hypothecates and transfers to Lender, and
hereby grants to Lender a present and continuing first priority security
interest in and lien on all of Debtor's right, title and interest in, to and
under the Collateral; but none of Debtor's (and/or any other party's of any kind
whatsoever) obligations, liabilities and/or duties of any kind whatsoever under,
or with respect to the Collateral. Notwithstanding anything to the contrary
contained herewith or otherwise, the Lender does not by virtue of this
Agreement, the Collateral Assignment or otherwise assume any obligations,
liabilities and/or duties of any kind whatsoever of the Debtor (and/or of any
other party of any kind whatsoever) under, or with respect to, the Collateral
and the Lender shall not be responsible in any way whatsoever for the
performance by the Debtor (and/or by any other party of any kind whatsoever) in
connection with, relating to, or arising under, the Collateral.



                                       41
   42

        The security interest granted herein shall attach to each item of
Collateral at the time Debtor has any interest of any kind whatsoever in such
Collateral without any further action of any kind whatsoever.

        6.2 Lender Appointed as Attorney-in-Fact.

        (a) Debtor hereby irrevocably constitutes and appoints Lender and any
other officer or agent thereof, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of Debtor and in the name of Debtor or in its own name, from time to
time in Lender's discretion, for the purpose of carrying out the terms of this
Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Agreement. Debtor hereby ratifies all that said attorney shall
lawfully do or cause to be done by virtue hereof. To the extent permitted by
law, this power of attorney is a power coupled with an interest and shall be
irrevocable. Without limiting the generality of the foregoing, pursuant to such
appointment, the Lender shall have authority (i) to endorse Debtor's name on any
checks, notes, drafts or any other payments or instrument relating to the
Collateral which come into the Lender's possession or control, (ii) to execute,
sign, file and record UCC financing statements, UCC amendments and other lien
recordation documents with respect to any Collateral, and (iii) to settle
insurance claims with the applicable insurer and/or to collect any insurance
proceeds from the applicable insurer in connection with any casualty occurrence
or Event of Loss.

        (b) The powers conferred on Lender hereunder are solely to protect its
interest in the Collateral and shall not impose any duty upon it to exercise any
such powers. Lender shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers and neither it nor any of
its officers, directors, employees or agents shall be responsible to Debtor for
any act or failure to act.

                                       43
   44

time); or

        (h) any representation or warranty made by Guarantor in the Guaranty,

                                       44
   45

Lender) regarding any loan, lease, deferred purchase price agreement,

regarding any such loan, lease, deferred purchase price agreement, advancement
of credit or any other financing or credit arrangement or facility of any kind
whatsoever, or if the aggregate amount of the underlying agreement, indebtedness
or obligation regarding any such default of any such loan, lease, deferred

arrangement or facility of any kind whatsoever; or

        (l) either Debtor or Guarantor shall default in any payment,

arrangement or facility of any kind whatsoever or any other transaction,
condition, covenant, agreement or matter specifically referred to elsewhere in
this Section 7), if the aggregate amount of such respective payment,
indebtedness or obligation, or if the aggregate amount of the underlying
agreement, indebtedness or obligation regarding any such default, is in excess
of $250,000.00 and such default results in the acceleration of (or the request
for) any such payment, agreement, indebtedness or obligation unless such default
or acceleration is subject to a bona fide dispute between the Debtor or the
Guarantor and such other party and said dispute is being diligently contested by
the Debtor or the Guarantor in good faith and by appropriate proceedings,
provided, however, any such bona fide dispute and default shall be resolved and
cured within one hundred eighty (180) days after the occurrence of such default;
or

        (m) any judgment, attachment or garnishment against Debtor and/or the

                                       45
   46

or Guarantor shall terminate its existence by merger, consolidation, or sale of
substantially all of its assets or otherwise (except as otherwise expressly
permitted with regard to the Guarantor in Section 5.10 of this Agreement); or

        (o) if the Guarantor shall no longer continue to control one hundred
percent (100%) of Debtor's issued and outstanding stock at all times; or

        (p) if any person or group (as defined in Rules 13d-3 and 13-5 under the
Securities Act), becomes the "beneficial owner" (as defined in Rules 13d-3 and
13d-5 under the Securities Act) of a larger number of shares of common stock of
the Guarantor than the number of shares of which CHARLES F. WILLIS, IV and
members of his family (including children, brothers and sisters) is the
beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Securities Act);
or

        (q) if either Debtor or Guarantor is a publicly held corporation, there

case may be, stock such that the Debtor or Guarantor, as the case may be, is no
longer subject to the reporting requirements of the Securities Exchange Act of
1934, or no longer has a class of equity securities registered under Section 12
of the Securities Act of 1933; or

        (r) if a Lessee Event of Default has occurred under the Lease; or

        (s) if the Debtor ceases to be a wholly-owned Subsidiary of the
Guarantor.

        Notwithstanding Subsection (r) of this Section 7, Debtor shall have the
right, within ten (10) days after the Debtor has been given notice that a Lessee
Event of Default has occurred under the Lease, to cure, at its sole cost and
expense, any Lessee Event of Default under the Lease relating solely to the
Lessee's failure to pay any Monthly Rent, Maintenance Fees and other payments
expressly due the Debtor by the Lessee thereunder (each a "Lessee Payment
Default") by paying the Lender the applicable Monthly Rent, Maintenance Fees and
such other payments or amounts expressly due the Debtor by the Lessee under the
Lease (any such Monthly Rent, Maintenance Fees and other payments or amounts
hereinafter collectively, the "Lessee Cure Payment") within such ten (10) day
period; provided, however, that the Debtor shall only have the right to cure one
(1) Lessee Payment Default during the term of the Lease. The Debtor shall not,
as a result of exercising the right to cure any such Lessee Payment Default,
obtain any Lien on any of the Collateral (including any Monthly Rent,
Maintenance Fees or any other amounts payable under the Lease) for or on account
of any costs or expenses incurred in connection with the exercise of such right,
nor shall any claim 



                                       46
   47
of the Debtor against the Lessee or any other party for the repayment of such
costs or expenses impair the prior right and security interest of the Lender in
the Collateral (including any Monthly Rent, Maintenance Fees or any other
amounts payable under the Lease). Upon the receipt by the Lender of the Debtor's
payment of the applicable Lessee Cure Payment (in immediately available funds),
the Lender shall credit and apply any such payment to the applicable outstanding
Obligations, Maintenance Fees, Security Deposits and/or other amounts required
under this Agreement, as the case may be, as provided in Section 9.1, Section
10.13 or any other applicable section of this Agreement.

        SECTION 8. REMEDIES.

        8.1 Termination of Commitment. If an Event of Default specified in
subsections 7 (i) or (j) above shall occur, then, and in any such event, the
Commitment shall immediately terminate and the principal amount of the Note,
together with accrued interest thereon and all other amounts owing under or with
respect to this Agreement (including, without limitation, any prepayment premium
or fee calculated as of the date of the Event of Default which premium or fee
shall also be due and payable) shall become immediately due and payable without
any notice or other action by Lender, and if any other Event of Default shall
occur and be continuing, then, and in any such event, Lender may (a) terminate
forthwith the Commitment and/or (b) declare the Note to be forthwith due and
payable, whereupon the remaining principal amount of the Note, together with
accrued interest thereon and all other amounts owing under or with respect to
this Agreement (including, without limitation, any prepayment premium or fee
calculated as of the date of the Event of Default which premium or fee shall
also be due and payable), shall become immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived, anything contained herein or in the Note to the
contrary notwithstanding. During the continuance of any Event of Default
hereunder, Lender shall have the right to pursue and enforce any of its rights
and remedies under Section 8, Subsections 8.2 through 8.4, inclusive, hereof.

        8.2 Additional Remedies. Upon the occurrence of any Event of Default,
Lender may, at its sole option and discretion, in addition to any other rights
or remedies granted to it under this Agreement, at law or in equity or under any
other instrument or agreement securing, evidencing or relating to the
Obligations, exercise one or more of the following remedies with respect to any
or all of the Collateral: (a) cause Debtor to, at Debtor's expense, promptly
return such Collateral (or any portion thereof requested by Lender) to such
location as Lender may from time to time reasonably designate, or Lender, at its
option, may enter upon the premises where the Collateral (or any portion thereof


                                       47
   48
requested by Lender) is located and take immediate possession of and remove the
same by self-help (to the extent permitted by law), or summary proceedings or
otherwise all without liability to Lender for or by reason of damage to property
or such entry or taking possession; provided, however, that the Lender shall not
remove any Collateral in the possession of the Lessee under the Lease so long as
no default or event of default exists under the Lease; (b) sell any or all of
the Collateral at public or private sale or otherwise dispose of, hold, use,
operate, lease to others or keep idle the Collateral (or any portion thereof),
all as Lender in its sole discretion may determine and all free and clear of any
rights of Debtor; (c) remedy such default, including making repairs or
modifications to any Collateral, for the account of and the expense of Debtor
and Debtor agrees to reimburse Lender for all of Lender's reasonable costs and
expenses; (d) apply any security deposit or other cash collateral or sale or
remarketing proceeds of any Collateral at any time as it sees fit to reduce any
amounts due to Lender (other than any payments or amounts held in the Account
which are solely Maintenance Fees or Security Deposits which payments or amounts
shall be disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13
of this Agreement); and (e) exercise any other right or remedy which may be
available to it under applicable law and the UCC or proceed by appropriate court
action to enforce the terms hereof or to recover damages for the breach hereof.
In addition to the foregoing, Debtor shall continue to be liable for all
indemnities under this Agreement and the Note and for all legal fees and other
costs and expenses resulting from any Event of Default or the exercise of
Lender's remedies. Without limiting the generality of the foregoing, Lender
shall (i) have the right upon any public sale or sales, and, to the extent
permitted by law, upon any such private sale or sales to purchase the whole or
any part of the Collateral so sold, free of any right or equity of redemption in
Debtor, which right or equity is hereby expressly released, and/or (ii) apply
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale (after deducting all reasonable costs and expenses of every
kind incurred therein or incidental to the care, safekeeping or otherwise of any
or all of the Collateral or in any way relating to the rights of Lender
hereunder, including attorney's fees and legal expenses) to the payment in whole
or in part of the Obligations, in such order as Lender may elect and only after
so applying such net proceeds and after the payment by Lender of any other
amount required by any provision of law (including Section 9-504(1)(c) of the
UCC), need Lender account for the surplus, if any, to Debtor. To the extent
permitted by applicable law, Debtor waives all claims, damages, and demands
against Lender arising out of the repossession, retention or sale of the
Collateral. Debtor agrees that Lender need not give more than ten (10) days'
notice (which notification shall be deemed given when mailed, postage prepaid,
addressed to Debtor at its address set forth in Section 10.2. hereof or
delivered by overnight delivery service to the Debtor at such 



                                       48
   49

address) of the time and place of any public sale or of the time after which a
private sale may take place and that such notice is reasonable notification of
such matters. Debtor shall be liable for any deficiency if the proceeds of any
sale or disposition of the Collateral are insufficient to pay all amounts to
which Lender is entitled.

        8.3 Costs of Collection. Debtor shall be liable for, and also agrees to
pay, all costs, charges and expenses of Lender, including reasonable attorneys'
fees and disbursements, incurred by or on behalf of Lender with respect to (i)
any Event of Default, (ii) the collection of any of the Obligations, (iii) the



                                       49
   50

enforcement of any of its respective rights under this Agreement, at law or in
equity or otherwise and/or (iv) the exercise of any of Lender's rights or
remedies under this Agreement, at law or in equity or otherwise.

        8.4 Waivers. Without limiting the generality of any other terms of this
Agreement, Debtor hereby waives presentment, demand, protest or any notice,
except as expressly provided herein, (to the extent permitted by applicable law)
of any kind in connection with this Agreement or any Collateral.

        SECTION 9. ACCOUNT

        9.1 Account.

        (a) All proceeds of checks, notes, cash and other proceeds of the Lease
Receivables as well as all proceeds from the sale of the Engine, any securities
(other than securities issued by Debtor) and any other Collateral and other cash
receipts of every kind and nature (other than the proceeds of any other
borrowing or amount expressly permitted by this Agreement) shall be collected
into any account required by the Lender in its sole discretion (the "Account")
commencing on the date of this Agreement and at all times hereafter pursuant to
the terms of this Section 9.1. The Lender shall maintain the Account at all
times until the Loan and any and all other Obligations of the Debtor due or
owing to the Lender under this Agreement, the Note, the Collateral Assignment or
any agreement, instrument or document evidencing any other Obligations have been
paid in full. Simultaneously with the Debtor's execution of this Agreement, the
Debtor shall direct the Lessee to make all payments under the Lease directly to
the Lender and into the Account. The Debtor shall hold in trust for Lender and
immediately remit to Lender by depositing the same into the Account all checks,
notes, cash and other proceeds of the Lease Receivables as well as all proceeds
from the sale of the Engine, any securities (other than securities issued by
Debtor) and any other Collateral and other cash receipts of every kind and
nature (other than the proceeds of other borrowing or amount expressly permitted
by this Agreement). The Debtor agrees that all payments or amounts received in
the Account will be the sole and exclusive property of Lender. The Lender shall,
on the second (2nd) Business Day after which any payment or amount is received
into the Account, and on a provisional basis until the final receipt of good
funds, (i) credit and apply all payments or amounts held in the Account which
are Monthly Rent to the applicable monthly principal and interest installment
due under the Note and any other outstanding amounts due or payable under the
Note and this Agreement, (ii) so long as no Lessee Event of Default exists under
the Lease, hold all payments or amounts held in the Account which are solely
Maintenance Fees and/or Security Deposits pursuant to the terms of this Section
9 and/or Section 10.13 of this Agreement, and (iii) so long as no Event of
Default exists under this Agreement, the Note, the Collateral Assignment or any
agreement, instrument 



                                       50
   51

or document evidencing any other Obligations, disburse the remaining amounts
held in the Account (after application to the payments or amounts due or payable
under the Note and this Agreement as provided in subclause (i) above) which are
not Maintenance Fees or Security Deposits expressly due or payable under the
Lease (or are not accrued interest on any Maintenance Fees or Security Deposits)
to the Debtor by wire transfer to Wells Fargo Bank, San Francisco, CA 94163, ABA
No. 121 000 248, Account No. 4518-101423 or to such other address or bank
account requested by the Debtor pursuant to the notice provisions of Section
10.2 of this Agreement. Upon the occurrence of an Event of Default under this
Agreement, the Note, the Collateral Assignment or any agreement, instrument or
document evidencing any other Obligations, the Lender shall, on the second (2nd)
Business Day after which any payment or amount is received into the Account
(other than any payments or amounts held in the Account which are solely
Maintenance Fees or Security Deposits which payments or amounts shall be
disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13 hereof),
and on a provisional basis until the final receipt of good funds, credit and
apply all such payments or amounts (including, without limitation, any accrued
interest on any amounts contained in the Account) first, to any amounts due or
outstanding under the Note (including, without limitation, all principal,
accrued interest or any prepayment premium or fee calculated as of the date of
the Event of Default which premium or fee shall also be due and payable),
second, the remainder of any such payments or amounts, if any (or in the event
there are no amounts due or outstanding under the Note, all such payments or
amounts shall be applied), to any other amounts due or payable under this
Agreement, the Collateral Assignment, or any amounts due or outstanding under
any agreement, instrument or document evidencing any other Obligations, and
third, the remainder of any such payments or amounts, if any, to a cash
collateral account under the sole dominion and control of Lender until such
Event of Default is cured by Debtor pursuant to the applicable terms of this
Agreement or any other applicable agreement or waived by Lender in its sole
discretion. Any provisional credit hereunder is subject to reversal if the final
collection of a payment is not received by the Lender within five (5) Business
Days following the initial receipt of such payment and will thereafter be
credited when such payment is actually received in good funds. The Debtor agrees
that it shall promptly pay to the Lender $85.00 per month for the Lender's
administration of the Account, together with, if any, all other reasonable fees
charged, and all reasonable expenses incurred, by the Lender in connection with
the administration of the Account. The Lender shall send the Debtor monthly
invoices regarding the $85.00 monthly payment and any other reasonable fees or
expenses charged or incurred in connection with the Lender's administration of
the Account. Without in any way whatsoever limiting the generality of the terms
of this Agreement, the Note, the Collateral Assignment or any other terms and
conditions of any other agreement, instrument 



                                       51
   52

or document evidencing any other Obligations, Debtor hereby irrevocably appoints
Lender its attorney-in-fact to endorse Debtor's name on any checks, notes,
drafts or any other payments or instruments relating to such items (and/or any
Collateral) which come into the Lender's possession or control pursuant to the
Account and to take any other action of any kind whatsoever that the Lender
deems necessary or desirable in its sole discretion regarding the same and/or
the Account, including, without limitation, inserting missing dates on checks,
notes, drafts or any other payments or instruments and/or rejecting and/or
returning checks, notes, drafts or any other payments or instruments, without
being liable in any way whatsoever for wrongful dishonor or any other thing or
matter of any kind whatsoever. To the extent appropriate or permissible under
the applicable law, such power is coupled with an interest and shall be
irrevocable. In addition, such power shall terminate only upon the Debtor's
payment and/or performance, as the case may be, in full of all of the
indebtedness and/or obligations of any kind whatsoever owing or due to the
Lender by the Debtor. Neither the Lender nor its counsel will be liable for any
acts or omissions nor error of judgment or mistake of fact or law in connection
with the exercise and/or enforcement of its rights under this Section 9. Nothing
contained in this Agreement, the Collateral Assignment or any other agreement,
instrument or document evidencing any other Obligations or otherwise or any acts
or omissions of the Lender or its counsel shall be deemed, or construed, in any
way whatsoever as the Lender being in control of the management and/or affairs
of the Debtor (other than to exercise the rights granted to the Lender under
this Agreement, the Collateral Assignment or any other agreement, instrument or
document evidencing any other Obligations to, among other things, protect its
interest in the Collateral). The Debtor further agrees that the terms of this
Section 9 are in addition to, and do not in any way whatsoever limit, the terms
of this Agreement or any related cash management or lockbox agreements or
documents executed and/or delivered in connection herewith. However, in the
event of a conflict between the terms and provisions of this Section 9 and any
related cash management or lockbox agreements or documents executed and/or
delivered in connection herewith, the applicable terms and provisions of this
Section 9 shall control for all purposes. Notwithstanding anything to the
contrary contained in this Section 9 or otherwise, all payments, funds or
amounts received into the Account (including, without limitation, all Monthly
Rent, Maintenance Fees and Security Deposits) may also be commingled with the
Lender's other funds and no trust relationship of any kind whatsoever shall
exist between the Lender and the Debtor as to any such payments, funds or
amounts so deposited. No interest shall be payable with regard to any payments,
funds or amounts deposited into the Account except as otherwise expressly
provided in Section 9.1(b) hereof.

        (b) The amount of all existing Maintenance Fees and Security Deposits
only held in the Account shall bear interest at a variable rate equal to the
Libor Rate for each Interest Period. 



                                       52
   53

Any interest accrued on the Maintenance Fees and/or the Security Deposits
pursuant to the immediately preceding sentence for any Interest Period shall be
credited into the Account on the first day of each calendar month immediately
following said Interest Period or on the first Business Day of such calendar
month (said first day or first Business Day of each calendar month hereinafter
the "Interest Credit Day") so long as any such Maintenance Fees and/or Security
Deposits are required to be maintained in the Account pursuant to the terms of
this Section 9. The Maintenance Fees and/or the Security Deposits (including,
without limitation, any accrued interest thereon), shall not be released and/or
disbursed to the Debtor (or any other party) until any and all obligations
outstanding under the Note, the Collateral Assignment and this Agreement (other
than any obligations relating solely to any other agreement, instrument or
document between the Debtor and the Lender) have been fully paid and/or
performed, as the case may be, except as otherwise expressly provided in Section
9.1(c) hereof, provided, however, that upon the occurrence of any Event of
Default under this Agreement, the Note, the Collateral Assignment or any
agreement, instrument or document evidencing any other Obligations, the
Maintenance Fees and the Security Deposits (including, without limitation, any
accrued interest thereon), shall not be released and/or disbursed to the Debtor
until any and all Obligations outstanding by the Debtor under this Agreement,
the Note, the Collateral Assignment or any other agreement, instrument or
document between the Debtor and the Lender have been fully paid and/or
performed, as the case may be, except as otherwise expressly provided in Section
9.1(c) hereof; provided further, however, that nothing contained in the
foregoing proviso shall be deemed to limit, impair or adversely affect in any
way whatsoever the Lender's rights under this Agreement, the Collateral
Assignment or any other agreements, documents or instruments to set off, debit
or apply any Maintenance Fees, Security Deposits or any other amounts as
provided in Section 9.1(c) or Section 10.13 of this Agreement or any other
applicable section of this Agreement.

        (c) So long as no Lessee Event of Default exists under the Lease, upon
three (3) Business Days prior written notice by the Debtor to the Lender for the
release of any Maintenance Fees which are being held in the Account, and receipt
by the Lender from the Debtor of such documents (including, without limitation,
such documents required to be supplied by the Lessee under the Lease or the
General Terms Agreement relating to any such amounts) as the Lender shall
reasonably request to document the Lessee's right to such Maintenance Fees, the
Lender shall disburse directly to the Lessee (or the applicable vendor, supplier
or maintenance company performing the applicable maintenance work or to the
Debtor if the Debtor has already paid for any such maintenance work) on behalf
of the Debtor the amount of any Maintenance Fees which the Lender expressly
agrees shall be released from the Account (which approval or agreement shall be
in the reasonable determination of the Lender). Upon and after 



                                       53
   54

the occurrence of a Lessee Event of Default under the Lease (but without
limiting any rights of the Lender to debit, apply or set off any amounts in the
Account which are not Maintenance Fees or Security Deposits, including, without
limitation, all Monthly Rent and accrued interest in the Account), the Lender
shall have the absolute right to immediately debit the Account for any
Maintenance Fees and Security Deposits (and the amounts in the Account relating
to Maintenance Fees and Security Deposits shall be immediately released
accordingly), and apply the proceeds thereof first, to any amounts due or
outstanding under the Note (including, without limitation, all principal,
accrued interest or any prepayment premium or fee calculated as of the date of
the Event of Default which premium or fee shall also be due and payable),
second, the remainder of any such amounts, if any, to any other amounts due or
payable under this Agreement, the Collateral Assignment, or any amounts due or
outstanding under any agreement, instrument or document evidencing any other
Obligations, and third, the remainder of any such amounts, if any, to a cash
collateral account under the sole dominion and control of Lender until such
Event of Default is cured by Debtor pursuant to the applicable terms of this
Agreement or any other applicable agreement or waived by Lender in its sole
discretion; provided, however, that in the event the Debtor exercises its right
to cure one (1) Lessee Payment Default and pays the Lender the applicable Lessee
Cure Payment pursuant to the terms of the last paragraph of Section 7 of this
Agreement, upon the receipt by the Lender of the Debtor's payment of the
applicable Lessee Cure Payment (in immediately available funds), the Lender
shall credit any amounts into the Account which the Lender has set off or
debited against Maintenance Fees or Security Deposits only with a corresponding
amount from the Debtor's payment of the Lessee Cure Payment, and effective as of
any such credit such amounts shall be deemed Maintenance Fees and/or Security
Deposits, as the case may be, and, if applicable, the Lender shall also credit
or apply any remaining amounts of such payment as provided in Section 9.1(a),
Section 9.1(b) or Section 10.13 of this Agreement or any other applicable
section of this Agreement.

        SECTION 10. MISCELLANEOUS.

        10.1 No Waiver; Cumulative Remedies. No failure or delay on the part of
Lender in exercising any right, power or privilege hereunder or under the Note
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
No right or remedy in this Agreement is intended to be exclusive but each shall
be cumulative and in addition any other remedy referred to herein or otherwise
available to Lender at law or in equity; and the exercise by Lender of any one
or more of such remedies shall not preclude the simultaneous or later exercise
by Lender of any or all such other remedies. No express or implied waiver by
Lender of an Event of Default shall in any way be, or be construed to be, a
waiver of any future or 



                                       54
   55

subsequent Event of Default. After the occurrence of any Event of Default, the
acceptance by Lender of any installment of principal and interest or of any
other sum owing hereunder or under the Note shall not constitute a waiver of
such Event of Default, regardless of Lender's knowledge or lack of knowledge
thereof at the time of acceptance of any such payment, and shall not constitute
a reinstatement of this Agreement and/or the Note if Lender has sent Debtor a
notice of default, unless Lender shall have agreed in writing to reinstate this
Agreement and/or the Note and waive the Event of Default. To the extent
permitted by law, Debtor waives any rights now or hereafter conferred by statute
or otherwise which limit or modify any of Lender's rights or remedies under this
Agreement and/or the Note.

        10.2 Notices. All notices, requests and demands to or upon any party
hereto shall be deemed to have been duly given or made when received by

the United States mail, return receipt requested first class postage prepaid,

whether or not discoverable, and any Indemnified Liabilities for patent,
trademark or copyright infringement, provided, however, that Debtor shall have
no obligations thereunder with respect to Indemnified Liabilities arising from

        (c) If Debtor fails to perform or comply with any of its agreements
contained herein and Lender shall itself perform or comply, or otherwise cause
performance or compliance, with such agreement, the reasonable expenses of
Lender incurred in connection with such performance of compliance, together with
interest thereon at the rate provided for in the Note shall be payable by Debtor

thereof) now held or which may hereafter be held as security for this Agreement,
the payment of the Note and/or any Obligations, or may add any property as
security, or may release any party liable hereunder or under any applicable loan
documents or otherwise, all without releasing in any way the obligations or the
liability of the Debtor or any endorser or guarantor of Debtor or otherwise. The
Debtor hereby further expressly waives any right to require the Lender or any
other party to marshal any property or other collateral security of any kind
whatsoever (or any portion thereof) now held or which may hereafter be held as
security for this Agreement, the payment of the Note and/or any Obligations or

whatsoever at any time held, including, without limitation, any amounts or
proceeds (including, without limitation, any accrued interest) contained in the
Account (other than any Maintenance Fees or Security Deposits as expressly
provided below), and other indebtedness at any time owing by the Lender to or
for the credit or the account of the Debtor against any and all of the



                                       58
   59

obligations of the Debtor now or hereafter existing under this Agreement, the
Note, the Collateral Assignment or any agreement, document or instrument
evidencing any other Obligations, irrespective of whether or not the Lender
shall have made any demand under this Agreement, the Note, the Collateral
Assignment or any agreement, document or instrument evidencing any other
Obligations, and although such obligations may be unmatured; provided, however,
that the Lender shall not be authorized to set off any amounts in the Account
which are solely Maintenance Fees and/or Security Deposits without notice to the
Debtor or any other party until after the occurrence a Lessee Event of Default
under the Lease, and upon the occurrence of any such Lessee Event of Default,
the Lender shall have the right to set off and apply any and all Maintenance
Fees and/or Security Deposits without notice to the Debtor as provided in this
Section 10.13; provided further, however, that in the event the Debtor exercises
its right to cure one (1) Lessee Payment Default and pays the Lender the Lessee
Cure Payment pursuant to the terms of the last paragraph of Section 7 of this
Agreement, upon the receipt by the Lender of the Debtor's payment 
of the applicable Lessee Cure Payment (in immediately available funds), the
Lender shall credit any amounts into the Account which the Lender has set off or
debited against Maintenance Fees or Security Deposits only with a corresponding
amount from the Debtor's payment of the Lessee Cure Payment, and effective as of

Deposits, as the case may be, and, if applicable, the Lender shall also credit
or apply any remaining amounts of such payment as provided in this Section 10.13
or in Section 9.1(a) or Section 9.1(b) of this Agreement or any other applicable
section of this Agreement. The Lender agrees promptly to notify the Debtor after
any such set off and application, provided that the failure to give such notice
shall not affect the validity of such setoff and application. The rights of the
Lender under this Section 10.13 are in addition to any other rights and remedies
of any kind whatsoever (including, without limitation, other rights of setoff)
which the Lender may have.

        10.14 Primary Obligations. Notwithstanding anything to the contrary
contained herein or otherwise, the Debtor shall be, and remain, primarily and
fully liable and obligated for any and all Obligations and the performance of
all terms and conditions hereunder notwithstanding the Lease and the Lessee's
obligations thereunder.

        10.15 Assignment By Lender. Lender, may at any time, without notice to

not be unreasonably withheld or conditioned and shall be given or denied by the
Debtor and the Guarantor within ten (10) Business Days after receipt by the
Debtor and the Guarantor of any request by the Lender for such consent, and in
the event that the Debtor or the Guarantor do not object in writing to any such
request by the Lender within in such ten (10) Business Day period any such
failure to so object shall be deemed (without any further action of any kind
whatsoever) an absolute waiver of the Debtor's and the Guarantor's rights to
object to any such assignment, sale or transfer; provided further, however, that
no consent of any kind of the Debtor or the Guarantor shall be required for any
merger or consolidation between the Lender or any parent, affiliate or
subsidiary of the Lender and any Competitor of the Debtor or the Guarantor or
any Designated Lender of a Competitor of the Debtor or the Guarantor (or any
parent, affiliate or subsidiary of any such Competitor or Designated Lender).
Debtor agrees that the rights hereunder of any such assignee, lender, creditor,
mortgagee, transferee or Person of Lender shall not be subject to any defense,
setoff, recoupment, abatement, reduction, claim or counterclaim (collectively
the "Defenses") that Debtor has or may at any time have against Lender and/or
its agents, employees, officers, directors, shareholders, subsidiaries,
affiliates, successors, and assigns for any reason whatsoever; and Debtor hereby

Lender an acknowledgment of assignment in form and substance satisfactory to 



                                       60
   61

the requesting party which, among other things, reaffirms the basic terms and
conditions of this Agreement, the Note and/or the Obligations, and (ii) to
comply with the reasonable demands of any such assignee, lender, creditor,
mortgagee, transferee or Person of Lender in order to perfect any such
assignment or transfer, at Lender's sole expense.

conclusive and may be enforced in any other jurisdiction, within or outside the
United States of America, by suit on the judgment, a certified or exemplified
copy of which shall be conclusive evidence of the fact and the amount of the
liability.

Gentlemen:

        We have acted as general counsel for T-12 Inc., a California corporation

("Guarantor") in connection with the execution of the Engine Loan and Security
Agreement of even date (the "Agreement"), between Debtor and Fleet Capital
Corporation ("Lender") and the related transactions contemplated thereby. Terms
not otherwise defined herein shall have the defined meanings set forth in the
Agreement.

        We are familiar with the Debtor and the Guarantor, their respective
affairs, and their respective charter, by-laws, and corporate records. We have
examined originals or copies, certified or otherwise identified to our
satisfaction, or such records, instruments, decisions, certificates, and
documents, have made such inquiries as to questions of fact of officers and
representatives of Debtor and the Guarantor and have made such examinations of
laws, rules, regulations, orders, decrees, writs, judgments, awards,
injunctions, and the like, as are necessary and appropriate for purposes of
giving the opinions hereinafter expressed.

        Based upon the foregoing, it is our opinion:

        1.     Debtor is a corporation duly organized, validly existing and in
               good standing under the laws of the State of California, has the
               necessary authority and power to own the Engine and its other
               assets and to transact the business in which it is engaged, and
               is duly qualified to do business in each jurisdiction in which
               the conduct of its business or the ownership or operation of its
               assets requires such qualification.

        2.     Debtor is a citizen of the United States within the 


                                       1
   68

               meaning of Subtitle VII of Title 49 of the United States Code, as
               amended and recodified.

        3.     Debtor has full power, authority and legal right to execute and
               deliver the Agreement, the Note, the Collateral Assignment and
               all other instruments to be executed and delivered pursuant to
               the Agreement, to perform its obligations thereunder, to borrow
               thereunder and to grant the security interest created by the
               Agreement and the Collateral Assignment.

        4.     No consent of any other party (including any partners,
               stockholders, trustees or holders of indebtedness), and no
               consent, license, approval or authorization of, exemption by, or
               registration or declaration with, any governmental body,
               authority, bureau or agency is required in connection with the
               execution, delivery or performance by Debtor of the Agreement,
               the Note, the Collateral Assignment and any other instruments to
               be executed and delivered pursuant to the Agreement, or the
               validity or enforceability of the Agreement, the Note, the
               Collateral Assignment and any other instruments to be executed
               and delivered pursuant to the Agreement, except recordation of
               the Agreement with the FAA, which shall have been duly effected
               as of the Closing Date.

        5.     The execution, delivery and performance by Debtor of each of the
               Agreement, the Note, the Collateral Assignment and any other
               instruments to be executed and delivered pursuant to the
               Agreement does not and shall not violate any provision of any
               applicable law or regulation or of any judgment, award, order,
               writ or decree of any court or governmental instrumentality, will
               not violate any provision of the charter or by-laws of Debtor and
               will not violate any provision of or cause a default under any
               mortgage, indenture, contract, agreement or other undertaking to
               which Debtor is a party or which purports to be binding upon
               Debtor or upon any of its assets, and will not result in the
               creation or imposition of any Lien on any of the assets of Debtor
               other than the security interest intended to be created by the
               Agreement and the Collateral Assignment.

        6.     The Agreement, the Collateral Assignment and any other
               instruments to be executed and delivered pursuant to the
               Agreement have been duly 


                                       2

   69

               authorized, executed and delivered by Debtor and constitutes
               legal, valid and binding obligations of Debtor enforceable in
               accordance with their respective terms. The Note and the Schedule
               have been duly authorized, executed and delivered by Debtor and
               constitutes legal, valid and binding obligations of Debtor
               enforceable in accordance with their respective terms.

        7.     To the best of Debtor's actual knowledge, there is no action,
               suit, investigation or proceeding (whether or not purportedly on
               behalf of Debtor) pending or threatened against or affecting
               Debtor or any of its assets (a) which involves the Engine or any
               of the transactions contemplated by the Agreement, the Note, the
               Collateral Assignment and any other instruments to be executed
               and delivered pursuant to the Agreement; or (b) which, if
               adversely determined, could have an adverse effect upon the
               transactions contemplated by the Agreement, the Note, the
               Collateral Assignment and any other instruments to be executed
               and delivered pursuant to the Agreement or a material adverse
               effect on the business, operations or financial condition of
               Debtor.

        8.     On the Closing Date Debtor shall have good and marketable title
               to the Engine subject to no Liens except the security interest in
               favor of Lender and the interest of the Lessee in the Engine
               pursuant to the Lease.

        9.     On the Closing Date Lender shall have a legal, valid and
               continuing first and only priority security interest in the
               Collateral, free and clear of all other Liens except for the
               interest of the Lessee in the Engine pursuant to the Lease, and
               all filings, recordings or other actions necessary or desirable
               in order to establish, protect and perfect such security interest
               in favor of Lender as a perfected first and only priority
               security interest in the Collateral will have been duly effected,
               and all taxes, fees and other charges in connection therewith
               shall have been duly paid.

        10.    Debtor is not in default, and no event or condition exists which
               after the giving of notice or lapse of time or both would
               constitute an event of default, under any mortgage, indenture,
               contract, agreement, judgment or other undertaking to which
               Debtor is a party or which purports to be 


                                       3

   70

               binding upon Debtor or upon any of its assets, except for any
               such default, event or condition which, individually or in the
               aggregate, would not affect Debtor's ability to perform its
               obligations under the Agreement or any such mortgage, indenture,
               contract, agreement, judgment or other undertaking.

        11.    Guarantor is a corporation duly organized, validly existing and
               in good standing under the laws of the State of California, has
               the necessary authority and power to own and operate its assets
               and to transact the business in which it is engaged, and is duly
               qualified to do business in each jurisdiction where its failure
               to do so would adversely affect its business, operations or
               financial condition or its ability to perform under the Guaranty,
               the Pledge Agreement, the Stock Powers and all other instruments
               to be executed and delivered pursuant thereto and to perform its
               obligations thereunder.

        12.    Guarantor has full power, authority and legal right to execute
               and deliver the Guaranty, the Pledge Agreement, the Stock Powers
               and all other instruments to be executed and delivered pursuant
               thereto and to perform its obligations thereunder.

        13.    No consent of any other party (including any partners,
               stockholders, trustees or holders of indebtedness), and no
               consent, license, approval or authorization of, exemption by, or
               registration or declaration with, any governmental body,
               authority, bureau or agency is required in connection with the
               execution, delivery or performance by Guarantor of the Guaranty,
               the Pledge Agreement, the Stock Powers and all other instruments
               to be executed and delivered pursuant thereto, or the validity or
               enforceability of the Guaranty, the Pledge Agreement, the Stock
               Powers and all other instruments to be executed and delivered
               pursuant thereto.

        14.    The execution, delivery and performance by Guarantor of each of
               the Guaranty, the Pledge Agreement, the Stock Powers and all
               other instruments to be executed and delivered pursuant thereto
               does not and shall not violate any provision of any applicable
               law or regulation or of any judgment, award, order, writ or
               decree of any court or governmental instrumentality, will not
               violate any provision of the charter or 


                                       4

   71

               by-laws of Guarantor and will not violate any provision of or
               cause a default under any mortgage, indenture, contract,
               agreement or other undertaking to which Guarantor is a party or
               which purports to be binding upon Guarantor or upon any of its
               assets, and will not result in the creation or imposition of any
               Lien on any of the assets of Guarantor other than the security
               interest intended to be created by the Pledge Agreement.

        15.    The Guaranty, the Pledge Agreement, the Stock Powers and all
               other instruments to be executed and delivered pursuant thereto
               have been duly authorized, executed and delivered by Guarantor
               and constitute legal, valid and binding obligations of Guarantor
               enforceable in accordance with their respective terms.

        16.    There is no action, suit, investigation or proceeding (whether or
               not purportedly on behalf of Guarantor) pending or threatened
               against or affecting Guarantor or any of its assets (a) which
               involves the Collateral or the Pledge Stock or any of the
               transactions contemplated by the Agreement, the Guaranty, the
               Pledge Agreement, the Stock Powers and all other instruments to
               be executed and delivered pursuant thereto; or (b) which, if
               adversely determined, could have an adverse effect upon the
               transactions contemplated by the Agreement or a material adverse
               effect on the business, operations or financial condition of
               Guarantor.

        17.    On the Closing Date Guarantor shall have good and marketable
               title to the Pledged Stock subject to no Liens except the
               security interest created by the Pledge Agreement in favor of
               Lender.

        18.    On the Closing Date Lender shall have a legal, valid and
               continuing first and only priority security interest in the
               Pledged Stock, free and clear of all other Liens, and all
               filings, recordings or other actions necessary or desirable in
               order to establish, protect and perfect such security interest in
               favor of Lender as a perfected first and only priority security
               interest in the Pledged Stock will have been duly effected, and
               all taxes, fees and other charges in connection therewith shall
               have been duly paid.

        19.    Guarantor is not in default, and no event or condition exists
               which after the giving of notice 


                                       5

   72

               or lapse of time or both would constitute an event of default,
               under any mortgage, indenture, contract, agreement, judgment or
               other undertaking to which Guarantor is a party or which purports
               to be binding upon Guarantor or upon any of its assets, except
               for any such default, event or condition which, individually or
               in the aggregate, would have no material adverse affect on the
               Guarantor's ability to perform its obligations under the
               Guaranty, the Pledge Agreement, the Stock Powers or all other
               instruments to be executed and delivered pursuant thereto and to
               perform its obligations thereunder

                                              Very truly yours,
