is expressly agreed that anything herein contained to the contrary
notwithstanding, Borrower shall remain liable under the Borrower Documents to

IT
IS HEREBY COVENANTED AND AGREED by and between the parties hereto as follows:

 

ARTICLE I

DEFINITIONS

 

For
all purposes of this Mortgage, terms defined in the heading and recitals of
this Mortgage are used as so defined and capitalized terms used herein shall
have the respective meanings set forth in Appendix A hereto for all purposes of
this Mortgage (such definitions to be equally applicable to both the singular
and plural forms of the terms defined). 
Any agreement referred to below shall mean such agreement as amended,
supplemented and modified from time to time in accordance with the applicable
provisions thereof and of the other Operative Documents.  Unless otherwise specified, Section and
Article references are to Sections and Articles of this Mortgage.  Appendix A and each of Exhibits A through
F attached hereto are hereby incorporated herein by this reference.

 

ARTICLE
II

THE NOTES

 

SECTION
2.01.  Notes.  The Notes and Security Trustee’s form of
certificate of authentication to appear on the Notes shall each be
substantially in the form set forth on Exhibit B.  On the Closing Date, Borrower shall issue a
Note to Lender in an aggregate original principal amount in Dollars equal to
the Loan.  Such Note shall be subject to
the terms and conditions set forth in this Article II.

 

SECTION
2.02.  Terms of Notes.

 

(a)                                  Interest Rate.  The
Notes shall bear interest at the Floating Rate.

 

(b)                                 [intentionally omitted]

 

(c)                                  Floating Rate Loan.  The
following terms shall apply to a Floating Rate Loan:

 

(i)                                     Each Note shall bear interest on the unpaid
principal amount thereof from time to time outstanding from and including the
date thereof until such principal amount is paid in full at the Floating Rate
applicable to each Interest Period in effect with respect thereto.  Such interest on the Note shall accrue with
respect to each Interest Period at the Applicable Rate in effect for such
Interest Period and shall be due and payable in arrears on each Payment Date
noted in Annex A to each Note.

 

 

The Floating Rate in respect of each Interest
Period shall be determined by the Security Trustee by reference to the
definition of Floating Rate.  Security
Trustee shall provide written notice to the Borrower of the amount of interest
due on each Payment Date no fewer than five (5) business days prior to that
Payment Date (and if such notice is not timely received, Borrower shall be
deemed to have paid the amount of interest due for the applicable Interest
Period if it, at its election, (i) pays an amount equal to the interest payment
for the prior Interest Period, or (ii) pays an amount equal to the interest due
for the applicable Interest Period as reasonably calculated by Borrower in good
faith).  Notwithstanding the foregoing,
the final payment on the Notes shall be an amount sufficient to discharge in
full the unpaid principal amount, all accrued and unpaid interest and all other
amounts due and owing to all Note Holders under the Operative Documents.

 

(ii)                                  [intentionally omitted]

 

(iii)                               Interest shall be calculated on the basis of
a year of 360 days and the actual number of days elapsed.

 

(d)                                 Each Note shall bear interest at the Past Due
Rate on any principal thereof and interest and other amounts due thereunder,
hereunder and under the other Operative Documents, not paid when due (whether
at stated maturity, by acceleration or otherwise), for any period during which
the same shall be overdue, payable on demand by the Note Holder given through
Security Trustee.  Interest on past-due
amounts shall be calculated on the basis of a year of 360 days and the actual
days elapsed.  In the event the principal
of or interest on a Note or other amount payable thereunder or hereunder is not
paid in full when due (whether at stated maturity, by acceleration or
otherwise), the period applicable to the Past Due Rate shall be either (i) a
period commencing on the due date of such principal, interest or other amount
and ending on the next succeeding Business Day and thereafter each period
commencing on the last day of the preceding period and ending on the next
succeeding Business Day, or (ii) such other period or periods (not greater than
six months) as the Security Trustee may, at any time and from time to time
during the period the same remains past-due, select in its sole discretion for
the purpose of determining the Past Due Rate therefor.

 

(e)                                  The Notes shall be executed on behalf of
Borrower by one of its authorized officers. 
Notes bearing the signatures of individuals who were at any time the
proper officers of Borrower shall bind Borrower, notwithstanding that such
individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Notes or did not hold such offices at the
respective dates of such Notes.  No Notes
shall be issued hereunder except those provided for in Section 2.01 and
any Notes issued in exchange or replacement therefor pursuant to the terms of
this Mortgage.  Each Note issued under Section
2.01, Section 2.07 or Section 2.08 shall be dated the Closing
Date.  No Note shall be secured by or
entitled to any benefit under this Mortgage or be valid or obligatory for any
purpose, unless there appears on such Note a certificate of authentication in
the form provided for herein executed by Security Trustee by the manual
signature of one of its authorized officers and such certificate upon any Note
shall be conclusive evidence, and the only evidence, that such Note has been
duly authenticated and delivered hereunder.

 

SECTION
2.03.  [intentionally omitted]

 

SECTION
2.04.  Method of Payment.  Principal and interest and other amounts due
hereunder or under the Notes or in respect hereof or thereof shall be payable
in Dollars in immediately available funds prior to 11:15 A.M., New York City
time, on the due date thereof, to Security Trustee at such account or accounts
at such financial institution or institutions as the Note Holders shall have
designated to Security Trustee in writing, in immediately available funds for
distribution to the relevant Note Holders, such payment to be made, in the case
of any such designated account in New York City, New York, prior to

 

 

2:00 P.M., New York City time, on the due
date thereof.  If Security Trustee,
through negligence or willful misconduct, shall fail to make any such payment
as provided in the preceding sentence after its receipt of funds at the place
and prior to the time specified above, Security Trustee, in its individual
capacity and not as trustee, agrees to compensate the Note Holders for loss of
use of funds in a commercially reasonable manner, and Borrower shall have no
liability for and the Mortgage Estate shall not secure any such loss or any
overdue interest on the Notes in connection with any such failure of Security
Trustee to timely distribute funds. All such payments by Borrower and Security
Trustee shall be made free and clear of and without reduction for account of
all wire and other like charges.  Prior
to the due presentment for registration of transfer of any Note, Borrower and
Security Trustee may deem and treat the Person in whose name any Note is
registered on the Note Register as the absolute owner of such Note for the
purpose of receiving payment of all amounts payable with respect to such Note
and for all other purposes whether or not such Note shall be overdue, and
neither Borrower nor Security Trustee shall be affected by any notice to the
contrary.  If any sum payable under the
Notes or under this Mortgage falls due on a day which is not a Business Day,
then such sum shall be payable on the next succeeding Business Day together
with interest thereon at the Applicable Rate from and including the scheduled
due date to but excluding such next succeeding Business Day; provided,
that if such succeeding Business Day falls into the next calendar month, such
payment shall be made on the preceding Business Day.

 

SECTION
2.05.  Application of Payments.  Each payment of principal and interest or
other amounts due in respect of each Note shall, except as otherwise expressly
provided herein, be applied, first, to the payment of any amount (other
than the principal of or the Breakage Amount, if any, or interest on such Note)
due in respect of such Note, second, to the payment of the Breakage
Amount, if any, and interest on such Note (as well as any interest on overdue
principal and, to the extent permitted by law, interest and other amounts
payable thereunder) due thereunder, third, to the payment of the principal
of such Note then due and fourth, the balance, if any, remaining
thereafter, to the payment of the principal of such Note remaining unpaid (provided
that such Note shall not be subject to prepayment or purchase without the
consent of the affected Note Holder except as permitted by Sections 2.10
and 2.11).

 

SECTION
2.06.  Termination of Interest in
Mortgage Estate.  A Note Holder shall
not, as such, have any further interest in, or other right with respect to, the
Mortgage Estate when and if the principal amount of and the Breakage Amount, if
any, and interest on and other amounts due under all Notes held by such Note
Holder and all other sums due to such Note Holder hereunder and under the other
Operative Documents shall have been paid in full.

 

SECTION
2.07.  Registration, Transfer and
Exchange of Notes.  Security Trustee
agrees with Borrower that Security Trustee shall keep a register (herein
sometimes referred to as the “Note Register”) in which provisions shall
be made for the registration of Notes and the registration of transfers of
Notes.  The Note Register shall be kept
at the offices of Security Trustee or at the office of any successor Security
Trustee, and Security Trustee is hereby appointed “Note Registrar” for
the purpose of registering Notes and transfers of Notes as herein
provided.  Upon surrender for
registration of transfer of any Note at the offices, Borrower shall execute,
and Security Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Notes of a like aggregate principal
amount.  At the option of the Note
Holder, its Notes may be exchanged for other Notes of any authorized
denominations, of a like aggregate principal amount, upon surrender of the
Notes to be exchanged at the offices. 
Each new Note issued upon transfer or exchange shall be in a principal
amount of at least $1,000,000 (except as may be necessary to evidence the
entire outstanding principal amount of a Note) and dated the Closing Date.  Whenever any Notes are so surrendered for
exchange, Borrower shall execute, and Security Trustee shall authenticate and
deliver, the Notes which the Note Holder making the exchange is entitled to
receive.  All Notes issued upon any
registration of transfer or exchange of Notes shall be the valid obligations of
Borrower evidencing the same respective obligations, and entitled to the same
security and

 

 

benefits under this Mortgage, as the Notes
surrendered upon such registration of transfer or exchange.  Every Note presented or surrendered for
registration of transfer or exchange, shall (if so required by Security
Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to Security Trustee duly executed by the Note
Holder thereof or his attorney duly authorized in writing, and Security Trustee
may require evidence satisfactory to it as to the compliance of any such
transfer with the Securities Act. 
Security Trustee shall make a notation on each new Note or Notes of the
amount of all payments of principal previously made on the old Note or Notes
with respect to which such new Note is issued and the date to which interest
accrued on such old Note or Notes has been paid.  Security Trustee shall not be required to
register the transfer of or exchange any surrendered Notes as above provided
during the ten calendar day period preceding the due date of any payment on
such Notes.

 

Borrower
and Security Trustee shall treat the Person in whose name each Note is
registered on the Note Register as the Note Holder with respect thereto for all
purposes hereof until due presentment for registration of transfer as provided
in this Section 2.07.  Security
Trustee shall give Borrower and each Note Holder prompt notice of such transfer
of a Note under this Section 2.07. 
Each Note Holder, by its acceptance of a Note, agrees that any transfer
of any Note acquired by it hereunder shall not be effected unless the
transferee shall have delivered to Borrower and Security Trustee (1) a written
representation as to the matters specified in Section 7(b) and 7(d) of the Loan
Agreement and, notwithstanding the above, such transferee by its acceptance of
a Note shall be deemed to have made such a representation and (2) an agreement
to be bound by and comply with the provisions of the Loan Agreement and this
Mortgage binding on a “Lender” or “Note Holder” and, notwithstanding the above,
such transferee by its acceptance of a Note shall be deemed to have made such
agreement.

 

SECTION
2.08.  Mutilated, Destroyed, Lost or
Stolen Notes.  If any Note shall
become mutilated, destroyed, lost or stolen, Borrower shall, upon the written
request of the affected Note Holder, execute, and Security Trustee shall
authenticate and deliver in replacement thereof, a new Note in the same principal
amount, dated the date of such Note and designated as issued under this
Mortgage.  If the Note being replaced has
become mutilated, such Note shall be surrendered to Security Trustee and a
photocopy thereof shall be furnished to Borrower by Security Trustee.  If the Note being replaced has been
destroyed, lost or stolen, the affected Note Holder shall furnish to Borrower
and Security Trustee such security or indemnity as may be reasonably required
by them to hold Borrower and Security Trustee harmless and evidence
satisfactory to Borrower and Security Trustee of the destruction, loss or theft
of such Note and of the ownership thereof; provided, however,
that if the affected Note Holder is an original party to the Loan Agreement or
an Affiliate thereof, the written notice of such destruction, loss or theft and
such ownership and the written undertaking of such Note Holder delivered to
Borrower and Security Trustee to hold harmless Borrower and Security Trustee in
respect of the execution, authentication and delivery of such new Note shall be
sufficient evidence, security and indemnity. 
No transfer of a Note shall be effective unless recorded in the Note
Register.

the Engines subject to such Event of Loss), on the earlier of the date of
Borrower’s payment with respect to such Event of Loss in Section 4.01(d)
hereof and the last day permitted for such payment under said Section

of, or as a replacement for, a Note, shall be designated as having been issued
in connection with such Replacement Airframe and/or Replacement Engine, but
without any other change therein except as provided for in this Article II.

 

SECTION
2.13.  Increased Regulatory Costs;
Illegality.

 

(a)                                  If the enactment, adoption or promulgation,
after the Closing Date, of any applicable law or regulation or any change,
after the Closing Date, in any applicable law, rule, regulation, guidance or
ruling or any exceptions thereto (or any applicable published change, after the
Closing Date, in the interpretation thereof (whether or not having the force of
law) or any compliance by such Lender with any request from such authority (provided
that the observance thereof is in accordance with the reasonable practice of
lenders in the country concerned)) of general applicability by any
governmental, fiscal, monetary or other authority charged with the
administration or application thereof (in each of the foregoing cases which is
binding upon such Lender, in any applicable jurisdiction for purposes of
funding or maintaining any Note or the participation by such Lender in the
transactions contemplated hereby and by the other Operative Documents), (1)
shall make it unlawful for such Lender to fund or maintain its Note or (2)
shall:

 

 

(i)                                     impose, modify or deem applicable any
reserve, special deposit or similar requirement (including, without limitation,
any such requirement imposed by the Board of Governors of the Federal Reserve
System, but excluding any such requirement with respect to which such Lender is
entitled to compensation during the relevant interest period and excluding any
regulatory change the effect of which is the implementation of the Basle Accord
as in effect on the date hereof) against deposits with, or credit extended by,
such Lender by reason of the funding or maintaining of its Note;

 

(ii)                                  impose, modify or deem applicable a capital
adequacy requirement which such Lender can establish has the effect of
increasing the amount of capital required to be maintained by such Lender, but
only to the extent that such increase is directly attributable and allocable to
such Lender’s obligations to fund and maintain its Note; or

 

(iii)                               impose, modify or deem applicable any Tax
(not excluded from indemnification under Section 6(b) of the Loan Agreement),
or other governmental, monetary or other charge or other condition which in
each case is in the nature of such reserve, special deposit or similar
requirement;

 

and
the result of any of the foregoing clauses (i), (ii) and (iii) shall be to
increase in the aggregate and by a material amount the costs to such Lender,
but only to the extent that such increase is directly attributable and
allocable to funding and maintaining the Note (any such reserve, special
deposit, similar requirement, Tax or other governmental, monetary or other
charge or condition or capital adequacy cost being hereinafter collectively
referred to as an “Increased Cost”) then the Lender shall promptly
provide Security Trustee and Borrower with written notice of such event giving
rise to such illegality or Increased Cost; provided, that in assessing the
effect of such enactment, adoption, change or condition and determining such
Increased Cost, such Lender shall evaluate and apply the requirements in
respect of its Note hereunder in a manner which is no less favorable to
Security Trustee and Borrower than, and shall not discriminate in such
evaluation and application in relation to, and with respect to clauses (i) and
(ii) above, the other deposits with or credit extended by the Lender involving
other Persons, and with respect to clause (ii) above, comparable funding
obligations held by the Lender of the same type and category involving other
Persons. Such notice shall be accompanied by an officer’s certificate
describing in reasonable detail (A) the events giving rise to such illegality
or Increased Cost, (B) the basis for determining and allocating such Increased
Cost with respect to the Note and a statement to the effect that the determination
for such Increased Cost in connection with its obligations under its Note has
been made in a manner that does not discriminate against Security Trustee or
Borrower, and (C) a good faith estimate of the amount expected to be incurred
by the Lender (such estimate to set out in reasonable detail the basis on which
it has been prepared).

 

Within
thirty (30) days of the receipt of any invoice for Increased Cost incurred
following (or accompanying such notice), Borrower shall remit the amount of
such Increased Cost to such Lender.

 

Notwithstanding
any of the provisions hereof, such Lender shall not be entitled to serve notice
to cause a payment of Increased Cost if (I) the Lender (or any office, branch
or Affiliate thereof) incurred the relevant Increased Cost as a result of the
Lender’s (or any office, branch or Affiliate thereof) having acted in a manner
contrary to, or failed to act in a manner required by, the applicable laws,
rules, regulations, rulings or exceptions thereto or interpretations thereof or
(II) the relevant Increased Cost was imposed with respect to the period prior
to receipt by Borrower of the notice with respect thereto pursuant to the first
paragraph of this Section 2.13.

 

 

(b)                                 Borrower shall not be required to make
payments under this Section 2.13 to any Lender if (i) a claim hereunder
arises through circumstances peculiar to such Lender and which do not affect
commercial lenders in the same jurisdiction generally, (ii) such Lender is not
also seeking indemnification against similar increased costs, to the extent it
is entitled to do so, in transactions with substantial borrowers (it being
agreed that an officer’s certificate to the contrary from any such Lender shall
constitute conclusive evidence of such fact) or (iii) the claim arises out of a
voluntary relocation by such Lender of its lending office.

interest payable on any Payment Date or on overdue payments of principal and
interest shall be promptly distributed to pay in full the principal and
interest and other amounts (as well as any interest on overdue principal and,
to the extent permitted by law, on interest and other amounts) then due on or
in respect of the Notes to the Note Holders thereof ratably, without priority

(b)                                 Application of Other Amounts Held by Security
Trustee.  Except as otherwise provided in Section

Payment Date the full amount then distributable pursuant Section 3.01(a),
Security Trustee shall, if so requested in writing by a Majority in Interest of
Note Holders, distribute other payments of the character referred to in Sections
4.01(d)(vi) and 4.01(e)(ix) then held by it or thereafter received

Security Trustee as the result of a payment or prepayment described in Section
2.10, shall be applied to prepayment of the Notes and to all other amounts
payable thereunder or hereunder or under the other Operative Documents as

of any one Note Holder over any other such Note Holder.

 

(b)                                 Insurance Proceeds upon Event of Loss.  With
respect to any payment of insurance proceeds received by Security Trustee as a

any Engine, any such insurance proceeds so received shall be held by the
Security Trustee as security for the obligations of Borrower under the
Operative Documents and invested in accordance with the terms of Section
3.07, provided that, subject to Section 4.01(e)(ix), such
proceeds shall be released to Borrower upon Borrower’s written request upon the
replacement of such damaged Airframe or Engine as provided in Sections
4.01(d) and 5.06 hereof.  In
the event the Airframe or any Engine is replaced in accordance with Sections
4.01(d) and 5.06 hereof, provided that Borrower shall have fully
performed or, concurrently therewith, will fully perform the terms of Sections
4.01(d) and 5.06

 

 

hereof, Borrower may elect by written notice
to Security Trustee to apply such insurance proceeds directly to the
acquisition of the Replacement Airframe or Replacement Engine, as the case may
be.

 

(c)                                  Insurance Proceeds other than upon Event of
Loss.  With respect to any payment of insurance
proceeds otherwise than in respect of an Event of Loss, any insurance proceeds
so received by Security Trustee shall be held by Security Trustee as security
for the obligations of Borrower under the Operative Documents and invested in
accordance with the terms of Section 3.07, provided that, subject
to Section 4.01(e)(ix), such proceeds shall be released to Borrower upon
receipt by Security Trustee of evidence reasonably satisfactory to the Security
Trustee of the repair of such damage to the Airframe or Engine or as otherwise
provided in Section 4.01(e) hereof; provided, further,
that upon receipt from Borrower of evidence reasonably satisfactory to Security
Trustee that the damage giving rise to such payment shall be repaired, Borrower
may elect by written notice to Security Trustee to apply such insurance
proceeds to the repair of the Aircraft, Airframe or the Engine.

 

(d)                                 Proceeds from Government or Other Party.  Any
amounts received by Security Trustee directly or indirectly from any
Governmental Authority or other party (other than an insurer) pursuant to any
provisions of Section 4.01(d)(iii) shall be held by the Security
Trustee, as security for the obligations of Borrower under the Operative
Documents and shall be invested in accordance with the terms of Section 3.07
and at such time as the conditions for payment to Borrower specified in said Section
4.01(d)(iii) shall be fulfilled, such amount, and the proceeds of any
investments thereof, shall, to the extent not applied to such obligations of
Borrower, be paid pursuant to instruction to Borrower to the extent provided in
this Mortgage.

 

SECTION
3.03.  Payment After Event of Default,
etc.  Notwithstanding Section 3.02
and except as otherwise provided in Section 3.05(ii), all payments
received and amounts held or realized by Security Trustee after an Event of
Default shall have occurred and so long as such an Event of Default shall be
continuing and Security Trustee shall have foreclosed or enforced the Lien of
this Mortgage or after the Notes shall have become due and payable as provided
in Section 4.03, together with all payments or amounts then held by
Security Trustee as part of the Mortgage Estate, shall be promptly distributed
by Security Trustee in the following order of priority:

 

First, so
much of such payments or amounts as shall be required to reimburse Security
Trustee for any tax, fees, expense, charge or other loss incurred by Security
Trustee (to the extent reimbursable pursuant to the terms of this Mortgage not
previously reimbursed) (including, without limitation, the expenses of any
sale, taking or other proceeding, reasonable attorneys’ fees and expenses,
court costs, and any other expenditures incurred or expenditures or advances
made by Security Trustee in the protection, exercise or enforcement of any
right, power or remedy or any damages sustained by Security Trustee, liquidated
or otherwise, upon such Event of Default) shall be applied by Security Trustee
in reimbursement of such expenses;

 

Second, so
much of such payments or amounts remaining as shall be required to reimburse
the Note Holders in full for payments made pursuant to Section 5.03 (to
the extent not previously reimbursed) shall be distributed to such Note
Holders, and if the aggregate amount remaining shall be insufficient to reimburse
all such payments in full, it shall be distributed ratably, without priority of
any Note over any other, in the proportion that the aggregate amount of the
unreimbursed payments made by each such Note Holder pursuant to Section 5.03
bears to the aggregate amount of the unreimbursed payments made by all Note
Holders pursuant to Section 5.03;

 

Third, so
much of such payments or amounts remaining as shall be required to pay in full
to the Note Holders the Breakage Amount, if any, and all other amounts payable

or pursuant to any other provision of any

 

 

Operative Document and secured hereunder
(other than amounts payable pursuant to clause “second”, “fourth”,
or “fifth” of this Section 3.03) to Note Holders and remaining
unpaid shall be distributed to such Note Holders, and if the aggregate amount
remaining shall be insufficient to pay all such amounts in full, it shall be
distributed ratably, without priority of any Note over any other, in the
proportion that the aggregate amount due each Note Holder under this clause “third”
bears to the aggregate amount due all Note Holders under this clause “third”;

 

Fourth, so
much of such payments or amounts remaining as shall be required to pay in full
the aggregate amount of all accrued but unpaid interest to the date of
distribution on the Notes shall be distributed to the Note Holders, and if the
aggregate amount remaining shall be insufficient to pay all such amounts in
full, it shall be distributed ratably, without priority of any one Note over
any other, in the proportion that the aggregate amount of all accrued but
unpaid interest to the date of distribution on each Note bears to the aggregate
amount of all accrued but unpaid interest to the date of distribution on all
Notes;

 

Fifth, so
much of such payments or amounts remaining as shall be required to pay in full
the aggregate unpaid principal amount of all Notes shall be distributed to the
Note Holders, and if the aggregate amount remaining shall be insufficient to
pay all such amounts in full, it shall be distributed ratably, without priority
of any one Note over any other, in the proportion that the aggregate unpaid
principal amount of each Note bears to the aggregate unpaid principal amount of
all Notes;

 

Sixth, the
balance, if any, of such payments or amounts remaining thereafter shall be
distributed to Borrower.

 

SECTION
3.04.  Certain Payments.  (a) Except as otherwise provided in this

(b)                                 Except as otherwise provided in Sections

Borrower in respect of Security Trustee in its individual capacity or any Note
Holder pursuant to Section 6 of the Loan Agreement, directly to the Person
entitled thereto.

 

SECTION
3.05.  Other Payments.  Any payments received by Security Trustee
whose purpose or intended payee is not identified shall be held by Security
Trustee pending identification of the intended purpose of such payment, and
thereafter, if no provision as to the application thereof is made in this
Mortgage, shall be distributed by Security Trustee (i) to the extent received
or realized at any time prior to the payment in full of all obligations to the
Note Holders secured by the Lien of this Mortgage, in the order of priority
specified in Section 3.03, and (ii) to the extent received or realized
at any time after payment in full of all obligations to the Note Holders
secured by the Lien of this Mortgage, in the following order of priority:  first, in the manner provided in the
clause “first” of Section 3.03 and second, in the manner
provided in clause “seventh” of Section 3.03.

 

SECTION
3.06.  Payments to Borrower.  Any amounts distributed hereunder by Security
Trustee to Borrower shall be paid to Borrower by wire transfer of funds of the
type received by Security Trustee at the address and account set forth in

Permitted Investments as directed in writing by Borrower.  Unless otherwise expressly provided in this
Mortgage, any income realized as a result of any such investment, net of
Security Trustee’s reasonable fees and expenses in making such investment,
shall be held and applied by Security Trustee in the same manner as the
principal amount of such investment is to be applied and any losses, net of
earnings and such reasonable fees and expenses, shall be charged against the
principal amount invested.  Security
Trustee shall not be liable for any loss resulting from any investment required
to be made by it under this Mortgage other than by reason of its willful
misconduct or gross negligence or any negligence in the handling or application
of funds, and any such investment may be sold (without regard to its maturity)
by Security Trustee without instructions whenever Security Trustee reasonably
believes such sale is necessary to make a distribution required by this
Mortgage.

IV

COVENANTS; EVENTS OF DEFAULT;

REMEDIES OF SECURITY TRUSTEE

 

SECTION
4.01.  Covenants of Borrower.  So long as the Lien of the Mortgage has not
been discharged and terminated pursuant to the terms hereof, Borrower hereby
covenants and agrees as follows:

 

(a)                                  Liens.  Except as expressly permitted
hereby, Borrower will not directly or indirectly create, incur, assume or
suffer to exist any Lien on or with respect to the Aircraft, Airframe or
Engines, title thereto or any interest therein or in this Mortgage, except (i)
the Lien of this Mortgage, (ii) Liens for Taxes of Borrower either not yet due
or being contested in good faith by appropriate proceedings so long as such
proceedings do not involved any material risk of the sale, forfeiture or loss
of the Airframe or any Engine or any interest therein, (iii) materialmen’s,
mechanics’, workmen’s, repairmen’s, employees’, or other like Liens arising in
the ordinary course of Borrower’s business securing obligations that are not
overdue or are being contested in good faith by appropriate proceedings so long
as such proceedings do not involve any material risk of the sale, forfeiture or
loss of the Airframe or any Engine or any interest therein, (iv) Liens arising
out of any judgment or award against Borrower with respect to which at the time
an appeal or proceeding for review is being prosecuted in good faith by
appropriate proceedings diligently conducted and with respect to which there
shall have been secured and continuing a stay of execution pending such appeal
or proceeding for review, so long as such proceedings do not involve any
material risk of the sale, forfeiture or loss of the Airframe or any Engine or
any interest therein and (v) any other Lien with respect to which Borrower
shall have provided a bond or other security in an amount and under terms
reasonably satisfactory to Security Trustee. 
Borrower will promptly, at its own expense, take (or cause to be taken)
such actions as may be necessary duly to discharge any such Lien not permitted
above if the same shall arise at any time.

 

(b)                                 Registration, Maintenance and Operation;
Possession; Insignia.

 

(i)                                     Registration and Maintenance. 
Borrower, at its own cost and expense, shall:  (1) cause the Aircraft to be and to remain
duly registered with the FAA in the name of Borrower under the Transportation
Code; (2) maintain, inspect, test, service, repair, and overhaul (or cause to
be maintained, inspected, tested, serviced, repaired, and overhauled) the
Aircraft (and any engine that is not an Engine but that is installed on the
Aircraft) (A) so as to keep the Aircraft in as good condition and appearance as
when originally delivered to Borrower by the Manufacturer on the Acquisition
Date, ordinary wear and tear excepted, in good operating condition and in
compliance at all times with

 

 

Borrower’s FAA-approved maintenance program
for the Aircraft, as well as in compliance with Manufacturer’s or Engine
Manufacturer’s mandatory service bulletins and so as to maintain in full force
and effect any warranties of the Manufacturer or the Engine Manufacturer and to
keep the Aircraft in such condition as may be necessary to enable all
certificates, licenses, permits and authorizations required for the use and
operation of the Aircraft and each Engine and Part, including the airworthiness
certification for the Aircraft to be maintained in good standing at all times
(other than during temporary periods of storage, maintenance, or modification
in accordance with applicable regulations or when the FAA or other aviation
authority having jurisdiction over the Aircraft grounds Bombardier Regional Jet
Aircraft Model CL-600-2B19 aircraft) under (x) the Transportation Code, or (y)
the applicable laws of any other jurisdiction in which the Aircraft may then be
registered from time to time;  provided,
however, that Borrower may, in good faith, contest the validity or
application of any law, rule, regulation, order or bulletin in any reasonable
manner that does not materially adversely affect the respective interest of
Security Trustee or Lender in or to such Airframe or Engines or any Operative
Document and such contest or failure to comply will not result in any material
risk of loss, sale, forfeiture or damage to the Aircraft or any risk of civil
or criminal liability to Security Trustee or Lender; (B) in substantially the
same manner as Borrower maintains, inspects, tests, services, repairs or
overhauls similar aircraft operated by Borrower in similar circumstances and
without in any way discriminating against the Aircraft; (C) so as to comply
with any requirements under policies of insurance required to be maintained
hereunder; or (D) or such other manner as shall be approved by Security Trustee
whether by reason of its mortgaged status or otherwise; (3) promptly furnish or
cause to be furnished to Security Trustee such information as may be required
to enable Security Trustee to file any reports required to be filed by Security
Trustee with any Governmental Authority because of such person’s interest in
the Aircraft; and (4) maintain or cause to be maintained, in English, all
records, logs and other materials required to be maintained in respect of the
Aircraft by the FAA or the applicable regulatory agency or body of any other
jurisdiction in which the Aircraft may then be registered.

 

(ii)                                  Operation.  Borrower will not maintain,
use, locate, service, repair, overhaul or operate the Aircraft in violation of
any law or any rule, regulation, treaty, order or certificate of any
Governmental Authority (domestic or foreign) having jurisdiction, or in
violation of any airworthiness certificate, license or registration relating to
the Aircraft issued by any such authority or for a purpose for which it is not
designed or in violation of any requirements of insurance pursuant to Section
4.01(e) or in violation of any requirements as may be necessary to keep any
unexpired warranties of Manufacturer or Engine Manufacturer in full force and
effect.  If such law, rule, regulation,
treaty, order or certificate requires alteration of the Aircraft, Borrower will
conform thereto or obtain conformance therewith at no expense to Security
Trustee or Lender.  Notwithstanding the
foregoing, after Borrower shall have provided Security Trustee with a
certificate of a Responsible Officer stating all relevant facts with respect
thereto, (except for any mandatory grounding of the Aircraft by an aviation
authority having appropriate jurisdiction) Borrower may contest in good faith
the validity or application of any such law, rule, regulation, treaty, order,
certificate, license, registration or violation in any reasonable manner that
does not adversely affect Lender’s or Security Trustee’s respective interests
in or to the Aircraft or any Operative Document and such contest or
non-compliance will not result in any material risk of loss, forfeiture or
damage to the Aircraft or any risk of unindemnified civil or criminal liability
to Security Trustee or Lender.  In
addition, Borrower shall comply with the provisions of this Article 4
notwithstanding such contest.  If the
indemnities or insurance specified in Section 4.01(e) hereof, have not
been obtained, Borrower will not operate, use or locate the Aircraft in or to
any area excluded from coverage by any insurance required to be maintained by
the terms of Section 4.01(e) hereof, unless such operation results from
a hijacking, medical emergency, equipment malfunction, weather conditions,
navigational error, or other extraordinary events beyond the control of
Borrower, so long as Borrower diligently and in good faith proceeds to remove
the Aircraft from such area.   Unless the
Aircraft has been requisitioned for use by the United States Government pursuant
to Section 4.01(d)(iv) hereof and indemnification or insurance has been
provided in accordance with Section 4.01(e) hereof, the Aircraft

 

 

may not be operated, used or located in any
declared war zone or in any area that is an area of recognized hostilities
(except to leave any such zone or area), unless such operation results from a
hijacking, medical emergency, equipment malfunction, weather conditions,
navigational error, or other extraordinary events beyond the control of
Borrower, so long as Borrower diligently and in good faith proceeds to remove
the Aircraft from such area.

 

(iii)                               Registration. 
Borrower, at its own cost and expense, shall cause the Aircraft to be
duly registered as a United States aircraft under the Transportation Code in
the name of Borrower as the owner thereof, and shall not take any action or
fail to perform any act that would cause such registration not to remain
effective during the Term.

 

(iv)                              Possession.  Borrower will not, without the
prior written consent of Lender, lease or otherwise in any manner deliver,
transfer or relinquish possession of the Airframe or any Engine or install or
permit any Engine to be installed on any airframe other than the Airframe, provided
that so long as no Specified Default or Event of Default shall have occurred
and be continuing at the time of such lease, delivery, transfer or
relinquishment of possession or installation, Borrower may, without the prior
written consent of Lender or Security Trustee:

 

(1)                                  subject the Engines or engines then installed
on the Airframe to normal interchange agreements or any Engine to normal
pooling or similar arrangements, in each case customary in the airline industry
and entered into by Borrower in the ordinary course of its business with any
Certified Air Carrier, Engine Manufacturer, Manufacturer or an authorized
service center of either Manufacturer or Engine Manufacturer, in each case, not
then insolvent or subject to any bankruptcy, reorganization or similar
proceeding; 

 

(2)                                  deliver possession of the Airframe or any
Engine to the manufacturer thereof or to any other qualified institution for
testing, service, repair, maintenance or overhaul work on the Airframe or
Engine or any Part of any thereof or for alterations or modifications in or
additions to such Airframe or Engine to the extent required or permitted by the
terms of this Mortgage;

 

(3)                                  install an Engine on an airframe owned by
Borrower which airframe is free and clear of all Liens, except:  (A) Permitted Liens and those that apply only
to engines (other than Engines), appliances, parts, instruments, appurtenances,
accessories, furnishings and other equipment (other than Parts) installed on
such airframe (but not to the airframe as an entirety) that do not contemplate,
permit or require the transfer of title to such airframe or engine installed
thereon, and (B) the rights of third parties under interchange agreements that
would be permitted under Section 4.01(b)(iv)(1);

 

(4)                                  install an Engine on an airframe leased to
Borrower or purchased by Borrower subject to a conditional sale or other
security agreement, provided that (A) such airframe is free and clear of
all Liens, except:  (1) the respective
rights of the parties to the lease or conditional sale or other security
agreement covering such airframe, or their assignees, and (2) Liens of the type
permitted by Section 4.01(b)(iv)(3) and (B) such lease, conditional sale
or other security agreement effectively provides that such Engine shall not
become subject to the lien of such lease, conditional sale or other security
agreement, notwithstanding the installation thereof on such airframe; and

 

(5)                                  for a period not to extend beyond the end of
the Term, subject the Airframe or any Engine to: (1) the U.S. Civil Reserve Air
Fleet Program, (2) contracts with the U.S. government or any agency thereof the
obligations of which are supported by the full faith

 

 

and
credit of the U.S. government or (3) any wet lease or similar arrangement under
which Borrower maintains operational control of the Aircraft.

 

(6)                                  [intentionally omitted]

 

(v)                                 Insignia.  On or prior to the Closing
Date, or as soon thereafter as practicable, Borrower agrees to affix and
maintain (or cause to be affixed and maintained) in the cockpit of the Airframe
adjacent to the registration certificate therein and on each Engine a plainly
visible and fireproof nameplate having dimensions of not less than 10 cm x 7 cm
and bearing the inscription:

 

“Subject
to a security interest in favor of C.I.T. Leasing Corporation, as Security
Trustee”

 

(such
nameplate to be replaced, if necessary, with a nameplate reflecting the name of
any successor Security Trustee, in each case as permitted under the Operative
Documents).

 

Except
as above provided, Borrower will not allow the name of any Person to be placed
on the Airframe or on any Engine as a designation that might be interpreted as
a claim of ownership, provided that nothing herein contained shall
prohibit Borrower from placing its customary colors, name and insignia on the
Airframe or any Engine.

 

(vi)                              Holding Out.  Borrower agrees that it will
not at any time represent or hold out Lender or Security Trustee or any
Affiliate of any of them (and will use its best efforts to ensure that none of
Lender and Security Trustee or any Affiliate of any of them is not at any time
represented or held out) as being in any way connected or associated with any
operation of the Airframe, any Engine or any Part or any other operations or
carriage undertaken by Borrower.

 

(vii)                           No Pledging of Credit. 
Borrower is not authorized to, and agrees that it will not purport to,
pledge the credit of Lender or Security Trustee for any maintenance, service,
repairs, or overhauls of, modifications to, or changes or alterations in, the
Airframe, any Engine, or any Part, or for any other purpose whatsoever.

 

(c)                                  Replacement and Pooling of Parts;
Alterations, Modifications and Additions.

 

(i)                                     Replacement of Parts. 
Borrower, at its own cost and expense, will promptly replace or cause to
be replaced all Parts that 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, except as otherwise provided in Section
4.01(c)(iii) hereof.  All replacement
parts shall be owned by Borrower free and clear of all Liens (except Permitted
Liens, pooling arrangements permitted by Section 4.01(c)(ii) hereof and
replacement Parts temporarily installed on an emergency basis which are
replaced as promptly as practicable thereafter in accordance with the terms of
this Section 4.01(c)) and shall be in as good operating condition as, and shall
have a value, economic useful life and utility equal to or greater than, the
Parts replaced, assuming such replaced Parts were in the condition and repair
required to be maintained by the terms hereof. 
All Parts (other than Obsolete Parts) at any time removed from the
Airframe shall remain subject to the Lien of the Mortgage, no matter where
located, until such time as such Parts shall be replaced by parts that meet the
requirements for replacement parts specified above.  Immediately upon any replacement part
becoming incorporated or installed in or attached to the Airframe or any
Engine, without further act (subject only to Permitted Liens and any pooling
arrangement permitted by Section 4.01(c)(ii) hereof and except
replacement parts temporarily installed on an emergency basis which are
replaced as promptly as practicable thereafter in accordance with the terms of
this Section 4.01(c)), (i) such part shall become subject to the Lien of
the Mortgage and

 

 

shall be deemed a Part for all purposes
hereof to the same extent as each Part originally incorporated or installed in
or attached to the Airframe or such Engine and (ii) the replaced Part shall no
longer be subject to the Lien of the Mortgage and shall no longer be deemed a
Part hereunder.

 

(ii)                                  Pooling of Parts.  Any
Part removed from the Airframe or any Engine as provided in Section
4.01(c)(i) hereof may be subjected by Borrower to a pooling arrangement of
the type permitted by Section 4.01(b)(iv)(1) hereof, provided
that the part replacing such removed Part shall be incorporated or installed in
or attached to such Airframe or Engine in accordance with Section 4.01(c)(i)
hereof as promptly as practicable after the removal of such removed Part.  In addition, any replacement part may be
owned by any third party subject to such a pooling arrangement, provided
that Borrower, at its expense, as promptly thereafter as practicable, shall
either (1) cause such replacement part to become the property of Borrower, free
and clear of all Liens other than Permitted Liens or (2) replace such
replacement part with a further replacement part owned by Borrower, free and
clear of all Liens other than Permitted Liens.

 

(iii)                               Alterations, Modifications and Additions. 
Borrower, at its expense, will make (or cause to be made) such
alterations and modifications in and additions to the Airframe and Engines as
may be required to be made during the Term to comply with all applicable laws
and to meet the applicable standards of any airworthiness directives or any
other standard of the FAA (or any applicable regulatory agency or body of any
other jurisdiction in which the Aircraft may then be registered) and any
mandatory service bulletins of Manufacturer or Engine Manufacturer (such laws,
rules, regulations, FAA or other applicable regulatory agency requirements and
any mandatory bulletins, collectively “Airworthiness Requirements”); provided,
however, that, Borrower may, in good faith, contest the validity or
application of any Airworthiness Requirement in any reasonable manner that does
not adversely affect the respective interest of Security Trustee or Lender in
or to such Airframe or Engines or any Operative Document and such contest or
failure to comply will not result in any material risk of loss, sale,
forfeiture or damage to the Aircraft or any risk of unindemnified civil or
criminal liability to Lender.  Borrower
shall pay all costs of each Airworthiness Requirement.

 

In
addition, Borrower, at its expense, may from time to time make such alterations
and modifications or improvements to the Airframe or any Engine as Borrower may
deem desirable in the proper conduct of its business, including removal of
Parts that Borrower deems to be obsolete or no longer suitable or appropriate
for use on the Airframe or such Engine (“Obsolete Parts”), provided
that no such alteration, improvement modification, removal or addition (1)
impairs the condition or airworthiness of the Airframe or such Engine, or diminishes
the value, utility or remaining useful life of the Airframe or such Engine
below the value, utility or remaining useful life thereof immediately prior to
such alteration, modification, removal or addition, assuming the Airframe or
such Engine was then in the condition required to be maintained by the terms
contained herein, except that the value (but not the utility, condition,
airworthiness or remaining useful life) of the Airframe or any Engine may be
reduced by the value of Obsolete Parts that shall have been removed so long as
the aggregate original cost of all Obsolete Parts, which shall have been
removed and not replaced shall not exceed $300,000, and provided that,
to the extent required by applicable law or for the safe operation of the Aircraft
or performance of the function of the Part removed, replacements therefor are
installed on the Aircraft or (2) involves structural alterations to the
Aircraft that would require material realteration to restore the Aircraft to
its original passenger configuration or be inconsistent with the use of the
Aircraft as an aircraft in passenger configuration, provided, that any
alteration of the Aircraft from passenger configuration to non-passenger
configuration shall require the prior written consent of the Security Trustee
and Lender.  All parts incorporated or
installed in or attached or added to the Airframe or an Engine as the result of
such alteration, modification or addition shall, without further act, become subject
to the Lien of the Mortgage.  The
foregoing provisions of this second paragraph of subparagraph (iii) shall not
apply to Nonproprietary Parts, which Borrower may add to, or, so long as no
Event of Default has occurred and is continuing and

 

 

the Security Trustee has not commenced the exercise
of remedies pursuant to the terms set forth in this Mortgage, remove from, the
Aircraft in its sole and absolute discretion. 
In the event Borrower removes any Nonproprietary Part in accordance with
the immediately preceding sentence, such Nonproprietary Part shall not be
deemed a Part for any purposes herein or in the other Operative Documents.

 

(iv)                              No Liability for Alteration, Modification or
Addition; Grounding.  In no event shall
Security Trustee or Lender bear any liability or cost whatsoever for (v) any
alteration or modification or, or addition to, the Airframe or any Engine, (w)
any grounding of the Aircraft, (x) suspension of certification of the Aircraft,
(y) loss of revenue suffered by Borrower for any reason whatsoever, or (z) the
cost of Nonproprietary Parts.

 

(v)                                 Substitution of Engine.  So
long as no Event of Default exists and Borrower does not discriminate in its
selection of an engine to install on the Airframe based on its mortgaged
status, Borrower may at any time during the Term in its sole discretion
substitute any Engine for an Acceptable Alternate Engine.  Upon such substitution, Borrower shall comply
with the terms of Section 4.01(d)(ii) hereof to the same extent as if an
Event of Loss had occurred with respect to such Engine.

 

(d)
                              Loss, Destruction, Requisition, etc

 

(i)                                     Event of Loss with Respect to the Aircraft.  Upon
the occurrence of an Event of Loss with respect to the Airframe or the Airframe
and one or more Engines, Borrower shall (1) forthwith (and, in any event, within
ten days of such occurrence) give Security Trustee notice of such Event of Loss
and (2) within 60 days after such occurrence, give Security Trustee written
notice of its election to perform one of the following options (it being
understood that failure to give such notice shall be deemed an election of the
option set forth in clause (I) below). 
Borrower shall:

 

(I)                                    to the extent not paid to Security Trustee as
insurance proceeds, pay or cause to be paid to Security Trustee not later than
the earlier of (i) 180 days after the occurrence of such Event of Loss, (ii) 5
Business Days following the payment of insurance proceeds with respect to such
Event of Loss, or (iii) the Final Maturity Date, the then outstanding principal
amount of the Notes, together with accrued interest thereon to the date of such
payment, plus the Breakage Amount and all other amounts due to Note Holders and
the Security Trustee under the Operative Documents; or

 

(II)                                provided that no Specified Default or Event
of Default shall have occurred and be continuing, no later than 180 days
following such Event of Loss substitute an aircraft or an airframe or an
airframe and one or more engines, as the case may be.

 

At
such time as Security Trustee shall have received the amounts specified in (I)
above, the Lien of the Mortgage shall be terminated pursuant to, and in
accordance with, Section 9.01 hereof.

 

If
Borrower elects to substitute an aircraft (or an airframe or an airframe and
one or more engines, as the case may be), then Borrower shall, at its expense,
obtain good and marketable title to another aircraft (or an airframe or an
airframe and one or more engines that, together with the Engines or Engine
constituting a part of the Aircraft but not installed thereon at the time of
such Event of Loss, constitute the Aircraft) free and clear of all Liens (other
than the Lien of this Mortgage) and having at least the value, utility and
remaining economic useful life (as confirmed by an independent appraiser
selected by Security Trustee and reasonably acceptable to Borrower) and being
in as good condition as the Aircraft subject to such Event of Loss, in each
case assuming that the Aircraft had been maintained in accordance with the
terms hereof, provided that any aircraft, airframe or engine so substituted
hereunder shall be of the same or improved make and model as the Aircraft, and
in the case of an Engine, shall be an Acceptable

 

 

Alternate Engine; and prior to or at the time
of any such substitution Borrower, at its own expense, shall (1) cause such
replacement aircraft, airframe or engine to become subject to the Lien of this
Mortgage; (2) cause a Mortgage Supplement to be filed for recording pursuant to
the Transportation Code or the applicable laws, rules and regulations of any
other jurisdiction in which the Airframe may then be registered and cause a
financing statement or statement or other requisite documents of a similar
nature to be filed in such place or places as necessary in order to perfect the
security interests herein created; (3) furnish Security Trustee with such
evidence of Borrower’s title to such replacement aircraft and of compliance
with the insurance provisions of Section 4.01(e) hereof with respect to
such substituted property as Security Trustee may reasonably request and that
the substituted property has been entered into Borrower’s FAA-approved
maintenance program; and (4) provide an opinion of counsel, which counsel shall
be reasonably acceptable to Security Trustee, to the effect that Borrower holds
title to such replacement aircraft free and clear of all Liens (except the Lien
of this Mortgage) and Security Trustee shall be entitled to the benefits and
protection of Section 1110 of the Bankruptcy Code with respect to the aircraft
substituted hereunder to at least the same extent as the original Airframe and
Engine or Engines, as the case may be, and otherwise comply with the provisions
and satisfy the conditions set forth in Section 5.06 hereof.  For all purposes hereof, the property
substituted shall after such transfer be deemed part of the property leased
hereunder and shall be deemed an “Aircraft,” “Airframe” or “Engine,”
as the case may be.  No such substitution
shall result in the reduction of any amounts due under the Notes.  Borrower agrees to pay all reasonable out-of-pocket
costs and expenses (including without limitation, reasonable counsel fees and
disbursements and any costs incurred in connection with Section 5.06
hereof) of Security Trustee and Lender in connection with the foregoing
replacement.

 

(ii)                                  Event of Loss with Respect to an Engine.  Upon
the occurrence of an Event of Loss with respect to an Engine under
circumstances where an Event of Loss has not occurred with respect to the
Airframe, Borrower shall promptly (and in any event, within ten days after such
occurrence) give Security Trustee written notice thereof and shall, within 90
days after the occurrence of such Event of Loss, obtain good and marketable
title to an Acceptable Alternate Engine free and clear of all Liens (other than
the Lien of this Mortgage).  Borrower, at
its expense, will (1) cause a Mortgage Supplement to be filed for recording
pursuant to the Transportation Code or the applicable laws, rules and
regulations of any other jurisdiction in which the Airframe may then be
registered and cause a financing statement or statement or other requisite
documents of a similar nature to be filed in such place or places as necessary
in order to perfect the security interests herein created, (2) furnish Security
Trustee with such evidence of Borrower’s title to such Acceptable Alternate
Engine and of compliance with the insurance provisions of Section 4.01(e)
hereof with respect to such Acceptable Alternate Engine as Security Trustee may
reasonably request, (3) furnish Security Trustee with an opinion of Borrower’s
counsel to the effect that title to such Acceptable Alternate Engine is free
and clear of all Liens (except the Lien of this Mortgage), and (4) otherwise
comply with the provisions and satisfy the conditions set forth in Section
5.06 of this Mortgage.  For all
purposes hereof, each such Acceptable Alternate Engine shall, after such
conveyance, be deemed an “Engine.” 
No such substitution shall result in the reduction of any amounts due
under the Notes.  Borrower agrees to pay
all reasonable out-of-pocket costs and expenses (including without limitation,
reasonable counsel fees and disbursements) of Security Trustee and Lender in
connection with the foregoing replacement.

 

(iii)                               Application of Payments from Governmental
Authorities for Requisition of Title, etc.  Any payments (other than
insurance proceeds the application of which is provided for in Section
4.01(e) hereof) received at any time by Borrower from any Governmental
Authority or other person with respect to an Event of Loss resulting from the
theft, disappearance, destruction, condemnation, confiscation or seizure of, or
requisition of title to or use of, the Airframe or any Engine, will be applied
as follows:

 

 

(1)                                  if payments are received with respect to the
Airframe (or the Airframe and any Engine or engines then installed
thereon):  (A) unless the same are
replaced pursuant to Section 4.01(d)(i)(II) hereof, so much of such
payments as the then outstanding principal amount of the Loan, together with
accrued interest thereon to the date of such payment, plus all other amounts
due to Note Holders under the Operative Documents shall be applied in reduction
of Borrower’s obligation to pay such sums pursuant to Section 4.01(d)(i)
hereof if not already paid by Borrower, or, if already paid by Borrower, shall
be applied to reimburse Borrower for its payment of such sums, and following
the foregoing application, the balance, if any, of such payments shall be
distributed to Borrower; or (B) if such property is, or is to be, replaced pursuant
to Section 4.01(d)(i)(II) hereof, such payments shall be paid over to
the Security Trustee, and the Security Trustee shall pay such amounts to
Borrower, provided that Borrower shall have fully performed or,
concurrently therewith, will fully perform the terms of the last paragraph of Section
4.01(d)(i) hereof with respect to the Event of Loss for which such payments
are made; and

 

(2)                                  if such payments are received with respect to
an Engine under circumstances contemplated by Section 4.01(d)(ii) hereof,
so much of such payments remaining shall be paid over to Security Trustee, and
the Security Trustee shall pay such amounts to Borrower, provided that
Borrower shall have fully performed, or concurrently therewith will perform,
the terms of Section 4.01(d)(ii) hereof with respect to the Event of
Loss for which such payments are made.

 

(iv)                              Requisition for Use of the Aircraft by the
United States Government or Government of Registry of the Aircraft; Other
Government Payments.  In the event of the requisition for use of
the Airframe and the Engines or engines installed on the Airframe during the
Term not constituting an Event of Loss by the United States government or any
other Governmental Authority, Borrower shall promptly notify Security Trustee
of such requisition, and all of Borrower’s rights and obligations as set forth
in the Operative Documents with respect to the Aircraft shall continue to the
same extent as if such requisition had not occurred.  Except as set forth in Section
4.01(d)(iii) with respect to certain payments upon the occurrence of an
Event of Loss, all payments received by Borrower from the United States
government or any other Governmental Authority for the use of such Airframe and
Engines or engines, or any other payment by a governmental entity or Person
shall be paid over to, or retained by, Borrower.

 

(v)                                 Requisition for Use of an Engine by the
United States Government or any other Governmental Authority.  In
the event of the requisition for use of an Engine by the United States government
or any other Governmental Authority (other than in the circumstances
contemplated by Section 4.01(d)(iii) or Section 4.01(d)(iv)
hereof), Borrower shall replace such Engine hereunder with an Acceptable
Alternate Engine and Borrower shall comply with the terms of Section
4.01(d)(ii) hereof to the same extent as if an Event of Loss had occurred
with respect to such Engine.  Upon
compliance with Section 4.01(d)(ii) hereof, any payments received by
Borrower from such Governmental Authority with respect to such requisition
shall be retained by Borrower.

 

(vi)                              Application of Payments During Existence of a
Specified Default or an Event of Default.  Any amount referred to in this
Section 4.01(d) that is payable to or retainable by Borrower shall not
be paid to or retained by Borrower if at the time of such payment or retention
a Specified Default or an Event of Default shall have occurred and be
continuing, but shall be held by or paid over to Security Trustee as security
for the obligations of Borrower under this Mortgage and, if an Event of Default
shall have occurred and be continuing, applied against Borrower’s obligations
hereunder as and when due.  At such time
as there shall not be continuing any such Specified Default or Event of
Default, such amount shall be paid to Borrower to the extent not previously
applied in accordance with the preceding sentence.

 

 

(e)                                  Insurance.

 

(i)                                     Public Liability, Property Damage Liability,
and War Risk Insurance.  Except as provided in Section 4.01(e)(iv),
and subject to the provisions of Section 4.01(e)(vi), Borrower will
carry or cause to be carried, at its expense, with insurers of recognized
reputation and responsibility, comprehensive airline liability and products
liability insurance (including, without limitation, contractual, bodily injury,
passenger and property damage liability) insurance (exclusive of manufacturer’s
product liability insurance) with respect to the Aircraft, in an amount not
less than the amount set forth in Exhibit F hereto.  In addition, Borrower shall at all times
maintain war risk (aviation liability) insurance of the scope substantially
similar to the coverage provided by AVN 52D (or its equivalent) (but excluding
the limitation of liability set forth therein) as specified below, in an amount
(taking into consideration any insurance or indemnification provided by the
United States government or any agency or instrumentality thereof the
obligations of which are supported by the full faith and credit of the United
States government in accordance with Section 4.01(e)(viii) hereof) not
less than the amount set forth on Exhibit F hereto.  Further, all insurance described in this Section
4.01(e)(i) shall be at least of a scope and coverage (except as to dollar
requirements) as is customarily carried by United States based regional air
carriers engaged in the same or similar business, similarly situated with the
Borrower and operating similar aircraft and engines; excluding, however, for
purposes of the foregoing, regional carriers owned by, controlled by, or
otherwise covered under, a major carriers insurance policy unless Borrower also
has insurance coverage under a major carriers insurance policy.  For the avoidance of doubt, AVN 52D provides
insurance against the following risks (collectively, “War Risks”): (1)
war, invasion, acts of foreign enemies (whether war be declared or not), civil
war, rebellion, revolution, insurrection, martial law, military or usurped
power, or attempts at usurpation of power, (2) strikes, riots, civil commotions
or labor disturbances, (3) any act of one or more persons, whether or not
agents of a sovereign power, for political or terrorist purposes and whether or
not the loss or damage resulting therefrom is accidental or intentional, (4)
any malicious act or act of sabotage, (5) confiscation, nationalization,
seizure, restraint, detention, appropriation, requisition for title or use by
or under the order of any government (whether civil, military or de facto) or
public or local authority, and (6) hi-jacking or any unlawful seizure or
wrongful exercise of control of the aircraft or crew in flight (including any
attempt at such seizure or control) made by any person or persons on board the
aircraft acting without the consent of the insured.

 

(ii)                                  Insurance Against Loss or Damage to the
Aircraft.  Except as provided in Section 4.01(e)(iv),
and subject to the provisions of Section 4.01(e)(vi), Borrower shall
maintain or cause to be maintained in effect, at its expense, with insurers of
recognized reputation and responsibility, all-risk ground, taxiing and flight
aircraft hull insurance covering the Aircraft (including Engines and Parts
temporarily removed from the Aircraft), and fire and explosion coverage,
ingestion and lightning and electrical damage, and extended coverage and all-risk
property damage insurance, including fire and transit, covering Engines and
Parts while removed from the Aircraft and not replaced by similar components
(or while removed from the Aircraft and not destined to be reattached to the
Aircraft) insured on a replacement cost clause; provided that such
insurance shall at all times while the Aircraft is subject to this Mortgage be
for an amount on an agreed value basis not less than 110% of the then
outstanding principal amount of the Notes, together with accrued interest
thereon (the “Insured Amount”).  Further, Borrower shall at all times maintain
or cause to be maintained war risk (aircraft hulls) and governmental
confiscation insurance (other than by the government of registry of the
Aircraft) per the terms of AVN48B writeback except (b) or its equivalent
providing insurance against the following risks: (1) strikes, riots, civil
commotions or labor disturbances, (2) any malicious act or act of sabotage and
(3) hi-jacking or any unlawful seizure or wrongful exercise of control of the
aircraft or crew in flight (including any attempt at such seizure or control)
made by any person or persons on board the aircraft acting without the consent
of the insured.  Such insurance described
in the immediately preceding sentence shall be in an amount (taking into
consideration any insurance or indemnification provided by the United States

 

 

government or any agency or instrumentality
thereof the obligations of which are supported by the full faith and credit of
the United States government in accordance with Section 4.01(e)(viii)
hereof) not less than the Insured Amount. 
All insurance described in this Section 4.01(e)(ii) shall be at
least of a scope and coverage (except as to dollar requirements) as is
customarily carried by United States based regional air carriers engaged in the
same or similar business, similarly situated with the Borrower and operating
similar aircraft and engines; excluding, however, for purposes of the
foregoing, regional carriers owned by, controlled by, or otherwise covered
under, a major carriers insurance policy unless Borrower also has insurance
coverage under a major carriers insurance policy.

 

(iii)                               Application of Insurance Proceeds. 
Except during a period when a Specified Default or Event of Default has
occurred and is continuing, all losses will be adjusted by Borrower with the
insurers.  It is agreed that all
insurance payments received as the result of the occurrence of an Event of Loss
will be applied as follows:

 

(1)                                  If such payments are received with respect to
the Airframe (or the Airframe and the Engines installed thereon), (A) unless
such property is replaced pursuant to Section 4.01(d)(i)(II) hereof,
such payments as shall not exceed the then outstanding principal amount of the
Note, together with accrued interest thereon to the date of such payment, plus
all other amounts due to Note Holders under the Operative Documents shall be
applied in reduction of Borrower’s obligation to pay such amounts and the other
amounts payable under Section 4.01(d)(i), if not already paid by
Borrower, or, if already paid by Borrower, shall be applied to reimburse
Borrower for its payment of such amounts, and the balance, if any, of such
payments remaining thereafter will be paid over to, or retained by Borrower, or
(B) if such property is, or is to be, replaced pursuant to Section
4.01(d)(i)(II) hereof, such payments shall be paid over to Security
Trustee, and the Security Trustee shall pay such amounts to Borrower, provided
that Borrower shall have fully performed or, concurrently therewith, will fully
perform the terms of Section 4.01(d)(i)(II) hereof with respect to the
Event of Loss for which such payments are made.

 

(2)                                  If such payments are received with respect to
an Engine under the circumstances contemplated by Section 4.01(d)(ii)
hereof, such payments shall be paid over to Security Trustee, and the Security
Trustee shall pay such amounts to Borrower, provided that Borrower shall
have fully performed or, concurrently therewith, will fully perform the terms
of Section 4.01(d)(ii) hereof with respect to the Event of Loss for
which such payments are made.

 

(3)                                  The insurance payments for any property
damage loss to the Airframe or any Engine not constituting an Event of Loss
with respect thereto shall be paid over to, or retained by, Borrower if
$2,500,000 or less; otherwise, to Security Trustee.

 

(iv)                              Aircraft Not In Operation. 
During any period that the Airframe or an Engine while temporarily
removed from the Aircraft and not replaced by similar components, as the case
may be, is grounded and not in operation, Borrower may, so long as Borrower
takes reasonable measures to protect the Airframe and the Engines, carry or
cause to be carried as to such non-operating property, in lieu of the insurance
required by Sections 4.01(e)(i) and (e)(ii) above, and subject to
the provisions of Section 4.01(e)(vi), insurance otherwise conforming
with the provisions of Sections 4.01(e)(i) and (e)(ii), except that the
amounts of coverage, the scope of the risks and the type of insurance shall be
consistent with industry practice for similarly situated United States air
carriers in respect of the same or similar aircraft which are similarly
grounded and not in operation, provided that the amount of coverage, the scope
of risks and type of insurance shall be at least as favorable as from time to
time applicable to aircraft owned or leased by Borrower of the same type as the
Aircraft similarly grounded and not in operation; provided that subject
to the provisions of Section 4.01(e)(vi), Borrower shall maintain

 

 

insurance against risk of loss or damage to
the Aircraft in an amount at least equal to the Insured Amount during such
period that the Aircraft is on the ground and not in operation.

 

(v)                                 Reports, etc. 
Borrower will furnish, or cause to be furnished, to Security Trustee and
Lender on or before the Closing Date and during each calendar year thereafter
on or before the anniversary of the Closing Date a certificate of insurance and
broker’s letter of undertaking, signed by an independent firm of insurance
brokers reasonably acceptable to Security Trustee (the “Insurance Brokers”),
describing in reasonable detail the hull and liability insurance (and property
insurance for detached Engines and Parts) then carried and maintained with
respect to the Aircraft and stating the opinion of such firm that such
insurance complies with the terms hereof and that premiums have been paid.  Borrower will cause such Insurance Brokers to
agree to advise promptly Security Trustee and Lender in writing if the
Insurance Brokers cease to be the insurance brokers to Borrower, or of the
occurrence of any default in the payment of any premium and of any other act or
omission on the part of Borrower of which it has actual knowledge and that might
invalidate or render unenforceable, in whole or in part, any insurance on the
Aircraft as required by the terms hereof and to advise such Persons in writing
at least 30 days prior to the cancellation (but not scheduled expiration) or
material change or lapse of any insurance required to be maintained pursuant to
this Section 4.01(e).  In
addition, Borrower will also cause such Insurance Brokers to deliver to
Security Trustee, on or prior to the date of expiration of any insurance policy
referenced in a previously delivered certificate of insurance, a new
certificate of insurance, substantially in the same form as delivered by
Borrower to such parties on the Closing Date except for changes in the report
or the coverage consistent with the terms hereof.  If Borrower fails to maintain or cause to be
maintained insurance as herein provided, Security Trustee or any Note Holder
may at its sole option, but without any obligation to do so, provide such
insurance and, in such event, Borrower shall, upon demand, reimburse Security
Trustee, for the cost thereof to Security Trustee; provided, however,
that no exercise by Security Trustee of said option shall affect the provisions
of this Mortgage, including the provisions that failure by Borrower to maintain
insurance prescribed hereunder shall constitute an Event of Default.

 

(vi)                              Self-Insurance. 
Subject to the terms set forth in Exhibit E hereto, Borrower may
self-insure the risks required to be insured against pursuant to this Section
4.01(e).

 

(vii)                           Additional Insurance. 
Borrower may at its own expense carry insurance with respect to its
interest in the Aircraft in amounts in excess of that required to be maintained
by this Section 4.01(e).  Security
Trustee or Lender or any Affiliate thereof may carry for its or their own
account at its or their sole cost and expense insurance with respect to its
interest in the Aircraft, and such insurance does not adversely affect or
materially impair Borrower from carrying the insurance required by this Section
4.01(e) or adversely affect such insurance or the cost thereof (it being
understood that all salvage rights to the Airframe and Engines shall remain
with Borrower’s insurers).

 

(viii)                        Indemnification by Government in Lieu of
Insurance.  Notwithstanding any provisions of this Section
4.01(e) requiring insurance, Security Trustee agrees to accept, in lieu of
insurance against any risk with respect to the Aircraft, indemnification from,
or insurance provided by, the United States government or any agency or
instrumentality thereof the obligations of which are supported by the full
faith and credit of the United States government, against such risk in an
amount that, when added to the amount of insurance against such risk maintained
by Borrower shall be at least equal to the amount of insurance against such
risk otherwise required by this Section 4.01(e) (taking into account
self-insurance permitted by Section 4.01(e)(vi) hereof).  Any such indemnification or insurance
provided by the United States government or any agency or instrumentality
thereof shall provide substantially similar protection as the insurance
required by this Section 4.01(e). 
Borrower shall furnish, in advance of attachment of such indemnity or
insurance, a certificate of a Responsible Officer of Borrower confirming

 

 

in reasonable detail the amount and scope of
such indemnification or insurance and that such indemnification or insurance
complies with the preceding sentence.

 

(ix)                                Application of Payments During Existence of a
Specified Default or an Event of Default.  Any amount referred to in this
Section 4.01(e) that is payable to or retainable by Borrower shall not
be paid to or retained by Borrower if at the time of such payment or retention
a Specified Default or an Event of Default shall have occurred and be
continuing, but shall be held by or paid over to Security Trustee as security
for the obligations of Borrower under this Mortgage and, if an Event of Default
shall have occurred and be continuing, applied against Borrower’s obligations
hereunder as and when due.  At such time
as there shall not be continuing any such Specified Default or Event of
Default, such amount shall be paid to Borrower to the extent not previously
applied in accordance with the preceding sentence.

 

(x)                                   Terms of Insurance Policies.  Each
policy carried in accordance with Sections 4.01(e)(i) and (e)(ii)
hereof covering the Aircraft, and any policies taken out in substitution or
replacement for any such policies, (A) shall in the case of liability insurance
carried pursuant to Section 4.01(e)(i), including all war risk insurance
as required by such section, name the Additional Insureds as additional
insureds, and in the case of insurance carried pursuant to Sections
4.01(e)(i) and (e)(ii), name the Loss Payee as first loss payee (but
without imposing on any such party liability to pay premiums, calls or other
charges with respect to such insurance), (B) shall provide that if the insurers
cancel such insurance for any reason whatever, or if the same is allowed to
lapse for non-payment of premium or if any material change is made in the
insurance that adversely affects the interest of any Additional Insured under
this Agreement, such lapse, cancellation or change shall not be effective as to
any Additional Insured for 30 days (seven days in the case of war risk and
allied perils coverage) after receipt by the Insurance Broker of written notice
by such insurers of such lapse, cancellation or change, (C) shall provide that
the Additional Insureds shall have no liability for premiums, commissions,
calls, assessments, warranties or representations to underwriters, or advances
with respect to such policies, (D) shall provide that such insurance is primary
without right of contribution, (E) shall provide that in respect of the
respective interest of each Additional Insured under this Agreement in such
policies the insurance shall not be invalidated by any action or inaction of
Borrower or any other Person and shall insure the respective interests of the
Additional Insureds, as they appear under this Agreement, regardless of any
breach or violation of any representation, warranty, declaration or condition
contained in such policies by Borrower or, in the case of an Additional
Insured, the breach or violation by any other Additional Insured, (F) shall
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, (G) shall provide that the Additional Insured shall have
no responsibility for premium and the insurers shall waive any right of set-off
or counterclaim against the Additional Insureds except in respect of
outstanding premium in respect of the Aircraft and shall waive any rights of
subrogation against the Additional Insureds, (H) shall provide that (1) in the
event of a loss involving the Aircraft, Airframe, or an Engine for which
proceeds are in excess of $2,500,000, the proceeds in respect of such loss up
to the amount of the then outstanding principal amount of the Notes plus all other
amounts due to the Note Holders under the Operative Documents, together with
accrued interest thereon shall be payable, to Security Trustee as loss payee; provided,
that the application of such insurance proceeds shall be as provided in Section
4.01(e)(iii), with any amounts paid and held by Security Trustee for any
period being subject to Section 3.07 hereof; provided, further,
that in the case of any payment to Security Trustee otherwise than in respect
of an Event of Loss, Security Trustee shall, upon receipt of evidence
reasonably satisfactory to it that the damage giving rise to such payment has
been repaired, pay the amount of such payment, and any interest or income
earned thereon in accordance with Section 3.07 hereof, to Borrower or
its order (provided, that Borrower may elect by written notice to Security
Trustee to apply such insurance proceeds directly to the repair of the relevant
Airframe or Engine, as the case may be), and (2) the entire amount of any such
loss for which proceeds are $2,500,000 or less or the amount of any proceeds of
any such loss in excess of the

 

 

then outstanding principal amount of the
Notes, together with accrued interest thereon plus all other amounts due to the
Note Holders under the Operative Documents shall be paid to Borrower or its
order unless a Specified Default or an Event of Default shall have occurred and
be continuing and the insurers have been notified thereof by Security Trustee,
(I) shall specifically exclude coverage for any Additional Insured or Loss
Payee with respect to any claim arising out of the legal liability of such
Person as manufacturer, repairer, supplier or servicing agent of the Aircraft
and shall not operate to prejudice the rights of recourse of the underwriters
of such insurance against any such Additional Insured or Loss Payee where such
rights of recourse would have existed had such exclusion not been effected
under such policies, (J) shall be payable in Dollars, and (K) in the event the
hull “all risks” and hull war risks policies are placed separately, shall
contain AVS103 (or its equivalent) (being the current London market endorsement
for such).

 

Notwithstanding
the foregoing, in the event the insurance acquired by Borrower is subject to
the AVN 67B endorsement, to the extent the terms of such endorsement conflict
with the foregoing, the terms of AVN 67B shall apply.

 

(f)                                    Inspection.  At all reasonable times prior
to the termination of this Mortgage pursuant to Section 9.01 (but with
respect to each Person, so long as no Default relating to the maintenance of
the Aircraft or Event of Default shall have occurred and be continuing, no more
than once in any twelve month period for such Person), the Lender may conduct
an inspection of the Aircraft and any Engine and the books and records of
Borrower relative thereto and to this Mortgage. 
Such inspection of the Aircraft shall be limited to a visual,
walk-around inspection which may include boarding the Aircraft, but shall not
include opening any panels or bays (although those otherwise open may be
inspected), and, so long as no Event of Default shall have occurred and be
continuing, shall be conducted so as not to interfere with Borrower’s business
or operation and maintenance of the Aircraft; provided, that the
foregoing limitation regarding the opening of any panels or bays shall not
apply with respect to Lender if an Event of Default has occurred and is
continuing.  Upon the written request of
Security Trustee, Borrower will use reasonable efforts to, but shall not be
obligated to, give such Person notice of the next scheduled “C” check or other
heavy maintenance visit with respect to the Aircraft or any Engine and afford
such Person an opportunity to be present at the same (in exercise of its annual
inspection right) without interfering in any material respect with the
maintenance, operations or business of Borrower.  Borrower shall furnish Security Trustee or
any Note Holder such additional information concerning the location, condition,
use and operation of the Aircraft (including information normally maintained by
Borrower regarding flight hours and cycles) as Security Trustee or any Note
Holder may reasonably request, including the location of the Aircraft and the
times and places of scheduled heavy maintenance.  Neither Security Trustee nor any Note Holder
shall have any duty to make any such inspection and shall not incur any
liability or obligation by reason of not making any such inspection.  Except for any inspection in connection with
an existing Event of Default, Security Trustee or such Note Holder shall be
responsible for costs incurred with respect to any inspection of the Aircraft.

 

SECTION
4.02.  Event of Default.  “Event of Default” means the
occurrence of any of the following events (whatever the reason for such Event
of Default and whether such event shall be voluntary or involuntary or come
about or be effected by operation of law or pursuant to or in compliance with
any judgment, decree or order of any court or any order, rule or regulation of
any administration or governmental body):

 

(a)                                  the failure of Borrower to pay to Security
Trustee when due any payment of principal of, or interest on, any Note and such
failure shall have continued unremedied for 5 Business Days, or the failure of
Borrower to pay to Security Trustee or any other intended recipient when due
any other amount due and payable hereunder, or under any Note or the Loan
Agreement, and such failure shall have continued unremedied for 10 Business
Days after written notice of such failure to Borrower; or

 

 

(b)                                 Borrower shall fail to carry and maintain on
or with respect to the Aircraft (or cause to be carried and maintained)
insurance required to be maintained in accordance with the provisions of Section
4.01(e) hereof; or

 

(c)                                  Borrower or Guarantor shall have failed to
perform or observe (or caused to be performed and observed) in any material
respect any other covenant or agreement to be performed or observed by it under
any Operative Document, and such failure shall continue unremedied for a period
of 30 days after written notice thereof by Security Trustee or any Note Holder;
provided, however, that if Borrower shall have undertaken to cure
any such failure relating to maintenance, service, repair, overhaul or
modifications, and notwithstanding the reasonable diligence of Borrower in
attempting to cure such failure, such failure is not cured within such 30 day
period but is curable with future due diligence, there shall exist no Event of
Default under this Section 4.02(c) so long as Borrower is proceeding with
due diligence to cure such failure and shall in fact cure such failure within
150 days following such notice; or

 

(d)                                 any representation or warranty made by
Borrower herein or in any other Operative Document or any document or
certificate furnished by Borrower or Guarantor in connection herewith or
therewith or pursuant hereto or thereto shall prove to have been incorrect in
any material respect at the time made, and shall continue uncured (together
with any adverse consequence thereof) for a period of 30 days after the receipt
by Borrower of a written notice from Security Trustee or any Note Holder
advising Borrower of the existence of such incorrectness;

 

(e)                                  Borrower shall not be a Certificated Air
Carrier;

 

(f)                                    Guarantor shall fail to observe any covenant
regarding the transfer or assignment of the Guaranty contained in Section 5(i)
of the Loan Agreement and such failure shall continue uncured for a period of
15 days after written notice from Security Trustee or any Note Holder, or the
Guaranty shall be repudiated by Guarantor or shall otherwise cease to be in
full force and effect; or

 

(g)                                 the commencement of an involuntary case or
other proceeding in respect of Borrower or Guarantor in an involuntary case
under the federal bankruptcy laws, as now or hereafter constituted, or any
other applicable federal or state bankruptcy, insolvency or other similar law
in the United States or seeking the appointment of a receiver, liquidator,
assignee, custodian, trustee, sequestrator (or similar official) of Borrower or
Guarantor or for all or substantially all of its property, or seeking the
winding-up or liquidation of its affairs and the continuation of any such case
or other proceeding undismissed or unstayed for a period of 60 consecutive days
or an order for relief under Chapter 11 of the Bankruptcy Code with respect to
Borrower or Guarantor as debtor or any other order, judgment or decree shall be
entered in any proceeding by any court of competent jurisdiction appointing,
without the consent of Borrower, a receiver, trustee or liquidator of Borrower
or Guarantor, or for all or substantially all of its property, or sequestering
of all or substantially all of the property of Borrower or Guarantor and any
such order, judgment, decree, appointment or sequestration shall be final or
shall remain in force undismissed, unstayed or unvacated for a period of 60
consecutive days after the date of entry thereof; or

 

(g)                                 the commencement by Borrower or Guarantor of
a voluntary case under the federal bankruptcy laws, as now constituted or
hereafter amended, or any other applicable federal or state bankruptcy,
insolvency or other similar law in the United States, or the consent by
Borrower or Guarantor to the appointment of or taking possession by a receiver,
liquidator, assignee, trustee, custodian, sequestrator (or other similar
official) of Borrower or Guarantor or for all or substantially all of its
property, or the making by Borrower or Guarantor of any assignment for the
benefit of creditors or Borrower or Guarantor shall take any corporate action
to authorize any of the foregoing; or

 

 

(h)                                 one or more final judgment(s) is/are rendered
by one or more court(s) of competent jurisdiction against Borrower or Guarantor
for a total of more than $20 million (of if greater 20% of Borrower’s Tangible
Net Worth as of the date of Borrower’s then most recent quarterly or annual
financial statements), excluding any amount insured by a solvent insurer who
has admitted coverage for the underlying claim(s), and such judgment(s) is/are
not stayed or discharged, or fully bonded again, within 30 days of the date of
entry.

 

SECTION
4.03.  Remedies.  If an Event of Default shall have occurred
and be continuing, Security Trustee may, consistent with applicable laws, do
any of the following:

 

(a)                                  Security Trustee may, at the direction of a
Majority in Interest of Note Holders, by notice in writing to the Borrower,
declare the entire unpaid balance of the Notes to be immediately due and
payable (or, if an Event of Default of the type described in Section 4.02(f)
or (g) shall have occurred and be continuing, the Notes shall
automatically be immediately due and payable); and thereupon all such unpaid
balance, together with all accrued interest thereon and Breakage Amount, if
any, together with all other amounts due hereunder and under the Notes and the
Operative Documents shall be and become immediately due and payable without
presentment, demand, protest or notice, all of which are hereby waived;

 

(b)                                 Upon the written demand of Security Trustee
and at the Borrower’s expense, the Borrower shall promptly deliver possession
of the Airframe or any Engine and/or the records, logs and other documents at
any time maintained and retained with respect thereto as Security Trustee may
so demand to Security Trustee or its order in the manner and condition required
by, and otherwise in accordance with all the provisions of, this Mortgage, or
Security Trustee at its option may enter upon the premises where all or any
part of the Airframe or any Engine is located and take immediate possession of
and remove the same by summary proceedings or otherwise (and at Security
Trustee’s option, store the same at the Borrower’s premises until disposal
thereof by Security Trustee), all without liability accruing to Security Trustee
(other than that caused by Security Trustee’s willful misconduct or gross
negligence) for or by reason of such entry or taking of possession or removing
whether for the restoration of damage to property caused by such action or
otherwise.  The Borrower shall, at the
request of Security Trustee, promptly execute and deliver to Security Trustee
such instruments or other documents as Security Trustee may deem necessary or
advisable to enable Security Trustee or an agent or representative designated
by Security Trustee, at such time or times and place or places as Security
Trustee may specify, to obtain possession of all or any part of the Mortgage
Estate the possession of which Security Trustee shall at the time be entitled
to hereunder;

 

(c)                                  To the extent applicable, Security Trustee
shall have the rights and remedies of a secured party under the Uniform
Commercial Code as enacted in any jurisdiction in which any of the Mortgage
Estate may be located and, in any case, Security Trustee may immediately, directly
or by such agent as it may appoint, without demand of performance and (to the
extent permitted by applicable laws) without notice of intention to sell or of
time or place of sale or of redemption or other notice or demand whatsoever to
the Borrower, all of which are hereby expressly waived and without
advertisement, sell at public or private sale or otherwise realize upon the
whole, or from time to time any part, of the Mortgage Estate. If notice of any
sale or other disposition is required by law to be given, the Borrower hereby
agrees that a notice sent at least fifteen (15) days before the time of any
intended public sale, or of the time after which any private sale or other
disposition of the Mortgage Estate is to be made, shall be reasonable notice of
such sale or other disposition;

 

 

(d)                                 Security Trustee may, either after entry or
without entry, proceed by suit or suits at law or in equity to foreclose this
Mortgage and to sell at public or private sale in connection therewith all or,
from time to time, any part of the Mortgage Estate;

 

(e)                                  Security Trustee may hold, use, operate,
lease to others or keep idle the Aircraft, Airframe or any Engines as Security
Trustee in its sole discretion may determine, all free and clear of any rights
of the Borrower, and without any duty to account to the Borrower with respect
to such action or inaction or for any proceeds with respect thereto;

 

(f)                                    Security Trustee may commence legal
proceedings for the appointment of a receiver or receivers (to which Security
Trustee shall be entitled as a matter of right) to take possession of the
Mortgage Estate pending the sale thereof pursuant either to the power of sale
given in this Section 4.03 or to a judgment, order or decree made in any
judicial proceeding for the foreclosure or involving the enforcement of this
Mortgage;

 

(g)                                 Security Trustee may either directly or by
such agent as it may appoint or by means of a receiver appointed by a court
therefor, enter upon the premises of the Borrower, and any other premises where
any of the Mortgage Estate may be located, exclude the Borrower and all other
Persons therefrom and take immediate possession of the Mortgage Estate, using
all necessary force to do so;

 

(h)                                 [intentionally omitted]

 

(i)                                     Upon every taking of possession pursuant to
this Section 4.03, Security Trustee may, from time to time, make all
such expenditures for maintenance, insurance, repairs, replacements,
alterations, additions and improvements to and of the Mortgage Estate as
Security Trustee may deem proper.  In
each such case, Security Trustee shall have the right to hold, use, operate,
store, lease, control or manage the Mortgage Estate, and to exercise all rights
and powers of Borrower relating to the Mortgage Estate as Security Trustee
shall deem appropriate, including the right to enter into any and all such
agreements with respect to the use, operation, storage, leasing, control or
management of any of the Mortgage Estate. 
The Borrower shall promptly, upon demand therefor, reimburse the
Security Trustee for the amount of any expenditures, plus interest at the Past
Due Rate, made pursuant to this Section 4.03(i);

 

(j)                                     Security Trustee may (A) assert all claims
for damages in respect of the Aircraft or any Engine, arising as a result of
any default by the Engine Manufacturer or the Manufacturer in respect of the
Warranties, and (B) exercise any and all rights of Borrower to compel
performance of the terms of the Engine Warranties or the Aircraft Warranties,
as the case may be; or

 

(k)                                  Security Trustee shall have, and may
exercise, in addition to the aforesaid rights and remedies, all other rights
and remedies available hereunder, at law or in equity, or by statute, each of
which may be exercised singly or concurrently with any one or more other rights
or remedies.

 

SECTION
4.04.  Remedies Cumulative.  Each and every right, power and remedy given
to Security Trustee specifically or otherwise in this Mortgage shall be
cumulative and shall be in addition to every other right, power and remedy
herein specifically given or now or hereafter existing at law, in equity or by
statute, and each and every right, power and remedy whether specifically herein
given or otherwise existing may be exercised from time to time and as often and
in such order as may be deemed expedient by Security Trustee, and the exercise
or the beginning of the exercise of any power or remedy shall not be construed
to be a waiver of the right to exercise at the same time or thereafter any
other right, power or remedy.  No delay
or omission by Security Trustee in the exercise of any right, remedy or power

 

 

or in the pursuit of any remedy shall impair
any such right, power or remedy or be construed to be a waiver of any default
on the part of Borrower or to be an acquiescence therein.

 

SECTION
4.05.  Discontinuance of Proceedings.  In case Security Trustee shall have
instituted any proceeding to enforce any right, power or remedy under this
Mortgage by foreclosure, entry or otherwise, and such proceedings shall have
been discontinued or abandoned for any reason or shall have been determined
adversely to Security Trustee, then and in every such case, Security Trustee
and Borrower shall, subject to any determination in such proceedings, be
restored to their former positions and rights hereunder with respect to the
Mortgage Estate, and all rights, remedies and powers of Security Trustee shall
continue as if no such proceedings had been instituted.

 

SECTION
4.06.  Waiver of Past Defaults.  Upon written instructions from a Majority in
Interest of Note Holders, Security Trustee shall waive any past Default or
Event of Default hereunder and its consequences and, upon any such waiver, such
Default or Event of Default shall cease to exist and any Default or Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Mortgage, but no such waiver shall extend to any subsequent or other
Default Event of Default or impair any right consequent thereon; provided,
however, that in the absence of written instructions from all Note Holders,
Security Trustee shall not waive any Default or Event of Default (i) in the
payment of the principal of, or interest on, or other amounts due under, any
Note then outstanding, or (ii) in respect of a covenant or provision hereof
which, under the proviso to the first sentence of Section 8.01 or under
the last sentence of Section 8.01, cannot be waived without the consent
of each Note Holder.

 

SECTION
4.07.  Engine Warranties and Aircraft
Warranties.  Effective at any time
after an Event of Default has occurred, and for so long as such Event of
Default is continuing and thereafter until the Engine Manufacturer or the
Manufacturer, as the case may be, shall have received notice from Security
Trustee that all Events of Default have been cured or waived (which Security
Trustee hereby agrees promptly to give upon such cure or waiver), Borrower does
hereby constitute Security Trustee, its corporate successors and permitted
assigns, Borrower’s true and lawful attorney, irrevocably, with full power (in
the name of Borrower or otherwise) to ask, require, demand, receive, compromise
and give acquittance for any and all monies and claims for monies due and to
become due under, or arising out of, the Engine Warranties in respect of any
Engine or the Aircraft Warranties in respect of the Aircraft, for such period
as Security Trustee may exercise rights with respect thereto under this
Mortgage, to endorse any checks or other instruments or orders in connection
therewith and to file any claims or take any action or institute (or, if
previously commenced, assume control of) any proceedings and to obtain any
recovery in connection therewith that Security Trustee may reasonably deem to
be necessary or advisable with respect to such monies and claims for monies.  Security Trustee confirms expressly for the

conclusively on any notice of the occurrence and

 

 

continuance of an Event of Default given by
Security Trustee hereunder without inquiring as to the accuracy of, or the
entitlement of Security Trustee to give, such notice.

DUTIES OF SECURITY TRUSTEE

 

SECTION
5.01.  Notices.  (a) Notice of Event of Default.  If Security Trustee shall have knowledge of a
Default or of an Event of Default arising from a failure to pay any amount of
principal and interest due and owing, Security Trustee shall forthwith give
telephone notice thereof to Borrower and the Note Holders (promptly confirmed
by facsimile to such Persons not later than one Business Day thereafter).  Subject to Sections 4.06 and 5.03,
Security Trustee shall take such action, or refrain from taking such action,
with respect to any such Event of Default (including with respect to the
exercise of any rights or remedies hereunder) as Security Trustee shall be
instructed in writing by the Majority in Interest of Note Holders.  Subject to the provisions of Section 5.03,
if Security Trustee shall not have received instructions as above provided
within 20 calendar days after notice of such Event of Default to the Note
Holders, Security Trustee may, subject to instructions thereafter received
pursuant to the preceding provisions of this Section 5.01, take such
action, or refrain from taking such action, but shall be under no duty to take
or refrain from taking any action, with respect to any such Event of Default as
it shall be directed by the Majority in Interest of Note Holders.  In the event Security Trustee shall at any
time commence to foreclose or otherwise enforce the Lien of this Mortgage,
Security Trustee shall forthwith notify the Note Holders and Borrower.  For all purposes of this Mortgage, in the
absence of actual knowledge on the part of an officer in its offices, in the
case of Security Trustee, Security Trustee shall not be deemed to have
knowledge of any Default or any Event of Default (except, upon the failure of
Borrower to make scheduled payments of principal and interest on the Payment
Date, which failure shall constitute knowledge of a Default) unless notified in
writing by Borrower or one or more Note Holders.  This Section 5.01, however, is subject
to the condition that, if at any time after the principal of the Notes shall
have become due and payable pursuant to Section 4.03 and before any
judgment or decree for the payment of the money so due, or any thereof, shall
be entered, all overdue payments of interest upon the Notes and all other
amounts payable under the Notes (except the principal of the Notes which by
such declaration shall have become payable) shall have been duly paid, and
every other Default and Event of Default with respect to any covenant or
provision of this Mortgage shall have been cured, then and in every such case a
Majority in Interest of Note Holders may (but shall not be obligated to), by written
instrument filed with Security Trustee, rescind and annul such acceleration and
its consequences; but no such rescission or annulment shall extend to or affect
any subsequent Default or Event of Default or impair any right consequent
thereon.

 

(b)                                 Other Notices. 
Security Trustee will furnish to each Note Holder promptly upon receipt
thereof, duplicates or copies of all reports, notices, requests, demands,
certificates, financial statements and other instruments furnished to Security
Trustee under any Operative Document to the extent the same shall not have been
otherwise directly distributed to the Note Holders pursuant to the express
provision of any other Operative Document.

 

SECTION
5.02.  Action Upon Instructions.  Subject to the terms of Sections 5.01
and 5.03, upon the written instructions at any time and from time to
time of a Majority in Interest of Note Holders, Security Trustee shall take
such of the following actions as may be specified in such instructions:  (i) exercise such election or option, or make
such decision or determination, or give such notice, consent, waiver or
approval or exercise such right, remedy or power or take such other action
hereunder or under any other Operative Document or in respect of any part or
all of the Mortgage Estate as shall be specified in such instructions; (ii)
take such action with respect to, or to preserve or protect, the Mortgage
Estate (including the discharge of Liens) as shall be specified in such
instructions and as are consistent with this Mortgage; and (iii) take such
other action in respect of the subject matter of this Mortgage pursuant to the

 

 

terms hereof. 
Security Trustee will execute and Borrower will file or cause to be
filed such continuation statements with respect to financing statements
relating to the security interest created hereunder in the Mortgage Estate as
may be specified from time to time in written instructions of a Majority in
Interest of Note Holders (which instructions may, by their terms, be operative
only at a future date and which shall be accompanied by the execution form of
such continuation statement so to be filed).

 

SECTION
5.03.  Indemnification.  Security Trustee shall not be required to
take any action or refrain from taking any action hereunder (other than under
the first sentence of Section 5.01) unless Security Trustee shall have
been indemnified by the Note Holders against any liability, cost or expense
(including counsel fees) which may be incurred in connection therewith.  Security Trustee shall not be under any
obligation to take any action under this Mortgage and nothing in this Mortgage
contained shall require Security Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.  Security Trustee shall not be required to take
any action hereunder (other than under the first sentence of Section 5.01),
nor shall any other provision of this Mortgage be deemed to impose a duty on
Security Trustee to take any action, if Security Trustee shall have been
advised by counsel that such action is contrary to the terms hereof or is
otherwise contrary to law.

 

SECTION
5.04  No Duties Except as Specified in
Mortgage or Instructions.  Security
Trustee shall not have any duty or obligation to use, operate, store, lease,
control, manage, sell, dispose of or otherwise deal with the Aircraft or any
other part of the Mortgage Estate, or to otherwise take or refrain from taking
any action under, or in connection with, this Mortgage or any part of the
Mortgage Estate, except as expressly provided by the terms of this Mortgage or
as expressly provided in written instructions from Note Holders as provided in
this Mortgage; and no implied duties or obligations shall be read into this
Mortgage against Security Trustee. 
Security Trustee agrees that it will, in its individual capacity and at
its own cost and expense (but without any right of indemnity in respect of any
such cost or expense) promptly take such action as may be necessary to duly
discharge all Liens on any part of the Mortgage Estate which result from claims
against it in its individual capacity (i) resulting from any breach of any
representation, warranty or covenant made by Security Trustee in its individual
capacity contained in the Operative Documents or (ii) not related to the
mortgaging to it of the Aircraft or the administration of the Mortgage Estate
or any other transaction contemplated by or pursuant to the Loan Agreement or
any document included in the Mortgage Estate.

 

SECTION
5.05.  No Action Except Under
Operative Documents or Instructions. 
Borrower and Security Trustee agree that they will not use, operate,
store, lease, control, manage, sell, dispose of or otherwise deal with the
Aircraft or any other part of the Mortgage Estate except (i) in accordance with
the terms of the Operative Documents, or (ii) in accordance with the powers
granted or reserved to, or the authority conferred upon, Borrower and Security
Trustee pursuant to this Mortgage and in accordance with the express terms
hereof.

 

SECTION
5.06.  Replacement Airframes and
Replacement Engines.  At any time and
from time to time, any Airframe or Engine which has been (or is to be treated
as if the same had been) subject to an Event of Loss and may be replaced under Section
4.01(d)(i) or (d)(ii) hereof by a Replacement Airframe or
Replacement Engine, as the case may be, shall be replaced in accordance with
the provisions of this Section 5.06 and Section 4.01(d), and
Borrower shall, from time to time, direct Security Trustee to execute and
deliver to or as directed in writing by Borrower an appropriate instrument
releasing such Airframe and/or Engine, as appropriate, from the Lien of this
Mortgage and Security Trustee shall execute and deliver such instrument as

Trustee; Appointment of Successor. 
(a) Security Trustee or any successor thereto may resign at any time
without cause by giving at least 30 calendar days’ prior written notice to
Borrower and each Note Holder, such resignation to be effective upon the
acceptance of the trusteeship by a successor Security Trustee.  In addition, (A) a Majority in Interest of
Note Holders may at any time remove Security Trustee without cause by an
instrument in writing delivered to Borrower and Security Trustee and (B)
Borrower may, so long as no Specified Default or Event of Default shall be

writing delivered to Security Trustee. 
Borrower, in the case of either (A) or (B) of the immediately preceding
sentence, shall promptly notify each Note Holder thereof in writing, such
removal to be effective upon the acceptance of the trusteeship by a successor
Security Trustee.  In the case of the
resignation or removal of Security Trustee, a Majority in Interest of Note

such Note Holders.  If a successor
Security Trustee shall not have been appointed within 30 calendar days after
such notice of resignation or removal, Security Trustee, Borrower or any Note
Holder may apply to any court of competent jurisdiction to appoint a successor
Security Trustee to act until such time, if any, as a successor shall have been
appointed as above provided.  The
successor Security Trustee so appointed by such court shall immediately and
without further act be superseded by any successor Security Trustee appointed
as above provided within one year from the date of the appointment by such
court.

 

(b)                                 Any successor Security Trustee, however
appointed, shall execute and deliver to Borrower and to the predecessor
Security Trustee an instrument accepting such appointment, and thereupon such
successor Security Trustee, without further act, shall become vested with all
the estates, properties, rights, powers and duties of the predecessor Security
Trustee hereunder in the trusts hereunder applicable to it with like effect as
if originally named Security Trustee herein; but nevertheless upon the written
request of such successor Security Trustee, such predecessor Security Trustee
shall execute and deliver an instrument transferring to such successor Security
Trustee, upon the trusts herein expressed applicable to it, all the estates,
properties, rights and powers of such predecessor Security Trustee, and such
predecessor Security Trustee shall duly assign, transfer, deliver and pay over
to such successor Security Trustee all monies or other property then held by
such predecessor Security Trustee hereunder.

 

(c)                                  Any successor Security Trustee, however
appointed, shall be a United States Person and shall also be a bank or trust
company having a combined capital and surplus of at least

 

 

$100,000,000, if there be such an institution
willing, able and legally qualified to perform the duties of Security Trustee
hereunder upon reasonable or customary terms.

 

(d)                                 Any corporation into which Security Trustee
may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which
Security Trustee shall be a party, or any corporation to which substantially
all the corporate trust business of Security Trustee may be transferred, shall,
subject to the terms of paragraph (c) of this Section, be Security Trustee
under this Mortgage without further act.

 

SECTION

Trustees.  (a) At any time or times,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Mortgage Estate may at the time be located or in which any
action of Security Trustee may be required to be performed or taken or if Security
Trustee shall be advised by counsel satisfactory to it that it is so necessary
or prudent in the interests of the Note Holders, or in the event Security
Trustee shall have been requested to do so by a Majority in Interest of Note
Holders, Security Trustee, by an instrument in writing signed by it, and
without the concurrence of Borrower, may appoint one or more individuals or
corporations to act as separate trustee or separate trustees or co-trustee,
acting jointly with Security Trustee, or to act as separate trustee or trustees
of all or any part of the Mortgage Estate with such powers as may be provided
in an agreement supplemental hereto.

 

(b)                                 Security Trustee and, at the request of
Security Trustee, Borrower, shall execute, acknowledge and deliver all such
instruments as may be required by the legal requirements of any jurisdiction or
by any such separate trustee or separate trustees or co-trustee for the purpose
of more fully confirming such title, rights or duties to such separate trustee
or separate trustees or co-trustee and Borrower hereby makes, constitutes and
appoints Security Trustee its agent and attorney-in-fact for it and in its
name, place and stead to execute, acknowledge and deliver the same in the event
that Borrower shall not itself execute and deliver the same within 20 days
after receipt by it of such request so to do. 
Upon the acceptance in writing of such appointment by any such separate
trustee or separate trustees or co-trustee, it, he or they shall be vested with
such title to the Mortgage Estate or any part thereof, and with such rights and
duties, as shall be specified in the instrument of appointment, jointly with
Security Trustee (except insofar as local law makes it necessary for any such
separate trustee or separate trustees or co-trustee to act alone) subject to
all the terms of this Mortgage.  Any
separate trustee or separate trustees or co-trustee may, at any time by an
instrument in writing, constitute Security Trustee its or his attorney-in-fact
and agent with full power and authority to do all acts and things and to
exercise all discretion on its or his behalf and in its or his name.  In case any such separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, the
title to the Mortgage Estate and all assets, property, rights, powers, trusts,
obligations and duties of such separate trustee or co-trustee shall, so far as
permitted by law, vest in and be exercised by Security Trustee, without the
appointment of a successor to such separate trustee or co-trustee unless and
until a successor is appointed.

 

(c)                                  All provisions of this Mortgage which are for
the benefit of Security Trustee shall extend to and apply to each separate
trustee or co-trustee appointed pursuant to the foregoing provisions of this Section
7.02.

 

(d)                                 Every separate trustee and co-trustee
hereunder shall, to the extent permitted by law, be appointed and act and
Security Trustee shall act, subject to the following provisions and conditions:

 

(i)                                     all powers, duties, obligations and rights
conferred upon Security Trustee in respect of the receipt, custody, investment
and payment of monies shall be exercised solely by Security Trustee;

 

 

(ii)                                  all other rights, powers, duties and
obligations conferred or imposed upon Security Trustee shall be conferred or
imposed upon and exercised or performed by Security Trustee and such separate
trustee or separate trustees or co-trustee jointly except to the extent that
under any law of any jurisdiction in which any particular act or acts are to be
performed, Security Trustee shall be incompetent or unqualified to perform such
act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Mortgage Estate in any such
jurisdiction) shall be exercised and performed by such separate trustee or
separate trustees or co-trustee;

 

(iii)                               no power hereby given to, or with respect to
which it is hereby provided may be exercised by, any such separate trustee or
separate trustees or co-trustee shall be exercised hereunder by such Person
except jointly with, or with the consent of, Security Trustee; and

 

(iv)                              no trustee hereunder shall be personally
liable by reason of any act or omission of any other trustee hereunder.

 

If
at any time Security Trustee shall deem it no longer necessary or prudent in
order to conform to any such law, or take any such action or shall be advised
by such counsel that it is no longer legally required or necessary or prudent
in the interest of the Note Holders or in the event Security Trustee shall have
been requested to do so by a Majority in Interest of Note Holders, Security
Trustee shall execute and deliver a mortgage supplemental hereto and all other
instruments and agreements necessary or proper to remove any separate trustee or
separate trustees or co-trustee.

 

(e)                                  Any request, approval or consent in writing
by Security Trustee to any separate trustee or separate trustees or co-trustee
shall be sufficient warrant to such separate trustee or separate trustees or
co-trustee, as the case may be, to take such action as may be so requested,
approved or consented to.

 

(f)                                    Notwithstanding any other provision of this Section
7.02, the powers of any separate trustee or separate trustees or co-trustee
appointed pursuant to this Section 7.02 shall not in any case exceed
those of Security Trustee hereunder.

in, or enforcing the judgment of, any court, it is necessary for any Person to
convert a sum due hereunder in Dollars into another currency (the “Judgment
Currency”), the rate of exchange used shall be that at which in accordance
with normal banking procedures such Person could purchase Dollars with the
Judgment Currency on the Business Day preceding that on which final judgment is
given or the order of enforcement made.

 

(b)                                 The obligation of Borrower in respect of any
sum due from it to any Person hereunder shall, notwithstanding any judgment or
order of enforcement in such Judgment Currency, be discharged only to the
extent that on the Business Day following that on which final judgment is given
or the order of enforcement made, such Person may in accordance with normal
banking procedures purchase Dollars with the Judgment Currency; if the Dollars
so purchased are less than the sum originally due to such Persons in Dollars,
Borrower agrees, as a separate obligation and notwithstanding any such judgment
or order of enforcement, to indemnify any Person against such loss attributable
to any of its

 

 

obligations hereunder, and if the Dollars so
purchased exceed the sum originally due from Borrower, in Dollars, such Person
shall remit to Borrower such excess.  Any
additional amount due from Borrower under this Section 9.16 will be due
as a separate debt and shall not be affected by judgment or order of
enforcement being obtained for any other sums due under or in respect of this
Mortgage or any other Operative Document.
