     (D) The AUTHORITY shall have the right to set-off any past due amount(s)
owed the AUTHORITY by AIRLINE by applying all or a portion of AIRLINE's current

     Agreement) including aircraft arrivals, aircraft departures, AUTHORITY-
     Controlled Passenger Holdrooms, Maximum Certificated Gross Landed Weight of
     said aircraft arrivals, and Revenue Aircraft Arrivals, by aircraft type;

     (ii) AIRLINE's Originating Enplaned Passengers and Deplaned Passengers,
     separately identified, with deplanements segregated by terminating, and
     on-line and off-line transferring passengers;

     handled by AIRLINE for the month; and

     (iv) Statistics required by subparagraphs (i) through (iii) above, for each
     Airline ground-handled by AIRLINE for which AIRLINE has agreed to make such
     reports and which do not otherwise have an agreement with the AUTHORITY

<Page>

     (C) AIRLINE hereby agrees to cooperate as reasonably practical and possible
with the AUTHORITY in establishing procedures for electronic submission of the
reports required in this Section 602.

SECTION 603. FAILURE TO REPORT

     (A) If AIRLINE fails to furnish the AUTHORITY with complete reports as
required by Section 602 for any month, AIRLINE's Rentals, Fees, Charges and
Supplemental Charges shall be determined by assuming that the Maximum Gross
Landed Weight of AIRLINE's Revenue Aircraft Arrivals, Enplaned Passengers, and
Deplaned Passengers for such month were one hundred twenty-five percent (125%)
of the highest reported monthly Maximum Gross Landed Weight of Revenue Aircraft
Arrivals, Originating Enplaned Passengers, and Deplaned Passengers reported by
AIRLINE in the immediately preceding twelve month period and AIRLINE shall make
payment to the AUTHORITY for Rentals, Fees, and Charges, and Supplemental
Charges based upon said estimates. Any necessary adjustment in such Rentals,
Fees, Charges, or Supplemental Charges shall be calculated after an accurate
report is delivered to the AUTHORITY by AIRLINE for the month in question.
Resulting surpluses or deficits shall be applied as credits or charges to the
appropriate charges or invoices in the month succeeding reconciliation.

     (B) The AUTHORITY shall have the right to rely on said activity reports in
determining Rentals, Fees, Charges, and Supplemental Charges due hereunder.
AIRLINE shall have full responsibility for the accuracy of said reports. Late
payment and payment deficiencies due to incomplete or inaccurate activity
reports shall be subject to the late payment and late penalty charges as set
forth in Section 601(C) hereof.

     (C) The acceptance by the AUTHORITY of any AIRLINE payment shall not
preclude the AUTHORITY from verifying the accuracy of Airline's reports or
computations, or from recovering any additional payment actually due from
AIRLINE. Interest on any additional amount due shall accrue thereon from the
date the payment was originally due at the rate prescribed and calculated in
Section 601(C) hereof.

     (D) AIRLINE acknowledges that the AUTHORITY incurs additional
administrative expense if AIRLINE'S monthly reports are not filed when due, are
incomplete or are inaccurate. To compensate the AUTHORITY for this
administrative expense, AIRLINE agrees to pay the AUTHORITY a charge of $50.00
(increasing by $50 for each instance to a maximum of $250 per instance) for each
monthly report which is not complete or received by its due date. Said payment
shall be paid within thirty (30) days of the AUTHORITY'S invoice therefor. This
charge shall be, in addition to, and not in lieu of charges and reimbursements
required by Section 603(B) above.

Airline providing scheduled or charter passenger or all-cargo air transportation
service to and from the AIRPORT, having similar leased premises, facilities,
rights, and privileges and imposing similar obligations to those of AIRLINE

to AIRLINE hereunder.  Notwithstanding the foregoing provision, the AUTHORITY
reserves the right to charge for the AUTHORITY-controlled space and facilities
on a per use basis, and ground lease space at different rates.

     premises are provided to AIRLINE by the AUTHORITY, the AUTHORITY shall pay
     all costs resulting from such relocation, including the value of AIRLINE's
     unamortized improvements. All such costs shall be considered a cost of the

consideration shall be deferred upon receipt of requests for deferral by a
Majority In Interest, as defined and appropriate to each proposed Deferrable
Capital Expenditure. All such airline requests for deferral must be in writing
and submitted to the AUTHORITY by each individual carrier requesting deferral
within 30 days following the meeting described above or, in the event no such
meeting is requested, within 15 days following the distribution of the
AUTHORITY's notice described above. In the event a Majority In Interest requests
a deferral of a proposed Deferrable Capital Expenditure, the AUTHORITY shall not
undertake said Deferrable Capital Expenditure for at least 1-year

                                       58
<Page>

following the deferral request, or such shorter period if specified in the
written deferral requests by a Majority In Interest.  A Majority In Interest may
at any time eliminate any remaining portion of a 1-year deferral period for a
particular Deferrable Capital Expenditure by requesting such elimination in
writing to the AUTHORITY or by approving a request by the AUTHORITY to eliminate
the balance of the deferral period.  Following any deferral period set forth in
this Section, the AUTHORITY shall have the right to undertake such Deferrable
Capital Expenditure and include the cost thereof in the Authority Requirement
for the calculation of Landing Fees under Section 503 or Apron Fees under
Section 504 pursuant to this Agreement.  Absent requests for deferral by a
Majority in Interest of Signatory Airlines and Signatory Cargo Carriers, as
applicable, under the conditions provided herein, AUTHORITY may proceed with the
Deferrable Capital Expenditure and include the cost thereof in the Authority
Requirement for calculation of Landing Fees under Section 503 or Apron Fees
under Section 504.

SECTION 1003.  COST OVERRUNS

     A cost overrun for a Deferrable Capital Expenditure or any project listed
on Exhibit F shall be treated us a separate Deferrable Capital Expenditure.
However, AIRLINE agrees that in the event that such cost overrun is not the
result of a material change in the project's scope, AIRLINE shall not
unreasonably withhold its approval of the additional expenditure; provided,
however, AUTHORITY has made reasonable and diligent effort to complete the
project as originally defined within the projected cost as originally presented
to the Signatory Airlines, and Signatory Cargo Carriers if applicable.

                                   ARTICLE XI
           INSURANCE, DAMAGE TO LEASED PROPERTIES AND INDEMNIFICATION

SECTION 1101.  INSURANCE

     (A) GENERAL. AIRLINE shall provide and maintain adequate insurance in full
force and effect at all times during the term of this Agreement and all
extensions thereto, as set forth below, with limits as hereinafter stated,
insuring against the liabilities set forth below, if AIRLINE does not wish to
provide and maintain insurance coverage for its Affiliated Airlines operating at
the AIRPORT under this Agreement it shall cause such Affiliated Airlines to
provide and maintain such coverage as set forth below. Such insurance shall
include, by way of example but not by way of limitation, comprehensive general
liability coverage and automobile liability insurance coverage and shall not be
in amounts less than hereinafter stated.

     If any of the insurance is written as "claims made" coverage, then AIRLINE
agrees to keep and cause Affiliated Airlines operating at the AIRPORT under this
Agreement to keep such "claims made" insurance in full force and effect for at
least 5 years after the expiration or termination of this Agreement.

     (B) RISKS AND MINIMUM LIMITS OF COVERAGE.

     (i) COMMERCIAL GENERAL LIABILITY INCLUDING AIRCRAFT LIABILITY. AIRLINE and
     its Affiliated Airlines shall procure and maintain policies of insurance
     for commercial general liability insurance. Such insurance shall be in an
     amount not less than of One Hundred Million Dollars ($100,000,000) if tile
     largest number of available passenger and AIRLINE crew seats on any single
     aircraft regularly operated by AIRLINE at the AIRPORT is less than 70
     seats, or not less than Two Hundred Million Dollars ($200,000,000) if the
     largest number of available passenger and AIRLINE crew seats on any single
     aircraft regularly operated by AIRLINE at the AIRPORT is at least 70 seats
     In each case, such coverage shall be single limit liability with no annual
     aggregate.

     (ii) AUTOMOBILE LIABILITY INSURANCE. Five Million Dollars ($5,000,000)
     combined single limit per occurrence (for automobiles used by AIRLINE in
     the course of its performance under this Agreement, including AIRLINE's
     non-owned and hired autos).

     (iii) WORKERS' COMPENSATION AND EMPLOYER'S LIABILITY INSURANCE. Workers'
     Compensation Insurance and Employer's Liability Insurance in accordance
     with Ohio laws and regulations. With respect to Workers' Compensation
     Insurance, if AIRLINE elects to be self-insured, AIRLINE shall comply with
     the applicable requirements of law. If any portion of work is to be
     subcontracted, AIRLINE shall require the subcontractors similarly to
     provide such coverage (or qualify as a self-insured) for all the latter's
     employees to be engaged in such work. AIRLINE hereby covenants and agrees
     that the AUTHORITY, its officers, or employees will not be liable or
     responsible for any claims or actions occasioned by AIRLINE's failure to
     comply with the provisions of this subparagraph and that the
     indemnification provisions of this Agreement shall apply to this Section.

                                       60
<Page>

     It is expressly agreed that the employees of AIRLINE are not AUTHORITY
     employees for any purpose.

     (iv) CONTENTS INSURANCE. AIRLINE shall be solely responsible for obtaining
     insurance policies that provide coverage for losses of AIRLINE owned
     property. The AUTHORITY shall not be required to provide such insurance
     coverage or be responsible for payment of AIRLINE's cost for such
     insurance.

     (v) BUILDERS RISK INSURANCE. During any period of construction or
     reconstruction for which AIRLINE contracts, AIRLINE shall carry, or shall
     require its contractor or contractors to carry, a policy of Builders Risk
     Insurance in an amount sufficient to insure the value of the work. The
     AUTHORITY shall he named Loss Payee on Builders Risk coverage to the extent
     of the AUTHORITY's interest therein (except to the extent coverage relates
     to AIRLINE's equipment and personal property).

     (vi) DEDUCTIBLES AND SELF-INSURANCE RETENTION. AIRLINE agrees AUTHORITY may
     determine the reasonableness of retention and deductibles applicable to its
     coverage at the AIRPORT.

     (vii) ALL RISK. Covering AIRLINE improvements, trade fixtures, and
     equipment, including fire, lighting, vandalism, and extended coverage
     perils. The AUTHORITY shall be named Loss Payee on such coverage to the
     extent of the AUTHORITY's interest therein (except to the extent coverage
     relates to AIRLINE's equipment and personal property).

     (C) OTHER PROVISIONS.

     (i) FORM OF POLICIES. The insurance may be in one or more policies of
     insurance. Nothing the AUTHORITY does or fails to do shall relieve AIRLINE
     from its duties to provide the required coverage hereunder, and the
     AUTHORITY's actions or inactions shall not be construed as waiving the
     AUTHORITY's rights hereunder,

     (ii) ISSUERS OF POLICIES. The issuer of any policy shall be a financially
     sound insurance company of recognized responsibility and subject to the
     reasonable approval of the AUTHORITY. Such issuer shall be authorized to
     cover losses in the State of Ohio,

     (iii) INSURED PARTIES. Each policy, except those for Workers' Compensation
     and Employer's Liability, shall name the AUTHORITY (and its officers,
     agents, and employees) as Additional Insured as its interest may appear, to
     the extent of the AIRLINE's indemnification obligations under this
     Agreement on the issued certificate of insurance and all renewal
     certificates (such certificates to accurately reflect the AUTHORITY'S
     Additional Insured status on AIRLINE'S original policies and any renewals
     or replacements thereof during the term of this Agreement).

                                       61
<Page>

     (iv) DEDUCTIBLES. Without increasing, decreasing or expanding its duties
     under Section 1101(B) hereof, AIRLINE shall assume and bear any claims or
     losses to the extent of any deductible amounts and waives any claim it may
     ever have for the same against the AUTHORITY, its officers, agents, or
     employees; provided, however, that nothing herein stated shall diminish
     AIRLINE's rights or increase AIRLINE's obligations in respect to its
     undertakings or hold harmless defense and indemnification set forth in
     Section 1103 hereof.

     (v) CANCELLATION. Each policy shall expressly state that it may not be
     cancelled, materially modified or nonrenewed unless 30 days advance written
     notice is given in writing to the AUTHORITY by the insurance company.

     (vi) AGGREGATES. AIRLINE shall give written notice to the AUTHORITY within
     thirty (30) days of the date upon which total claims by any party against
     AIRLINE reduce the aggregate amount of coverage below the amounts required
     by this Agreement. In the alternative, the policy may contain an
     endorsement establishing a policy aggregate for the particular project or
     location subject to this Agreement.

     (vii) SUBROGATION.  Each policy shall contain an endorsement to the effect
     that the issuer waives any claim or right in the nature of subrogation to
     recover against the AUTHORITY, its officers, agents, or employees.

     (viii) ENDORSEMENT OF PRIMARY INSURANCE. Each policy hereunder except
     Workers' Compensation shall be primary insurance to any other insurance
     available to the Additional Insured and Loss Payee with respect to claims
     arising hereunder,

     (ix) LIABILITY FOR PREMIUM. AIRLINE shall be solely responsible for payment
     of all insurance premiums required hereunder, and the AUTHORITY shall not
     be obligated to pay any premiums.

     (x) PROOF OF INSURANCE. Within thirty (30) days of the Effective Date of
     this Agreement and at any time during the term of this Agreement, AIRLINE
     shall furnish the AUTHORITY with certificates of insurance. If reasonably
     requested in writing by the AUTHORITY, AUTHORITY shall have the right to
     examine AIRLINE's insurance policies.

     (D) Notwithstanding the proof of insurance requirements set forth above, it
is the intention of the parties hereto that AIRLINE, continuously and without
interruption, maintain in force the required insurance coverages to be carried
by AIRLINE set forth above.

     (E) AUTHORITY RIGHT TO REVIEW AND ADJUST COVERAGE LIMITS. The AUTHORITY
reserves the right at reasonable intervals during the term of this Agreement to
cause the insurance requirements of this Article XI to be reviewed by an
independent insurance consultant experienced in insurance for public airports,
taking into consideration changes in statutory law, court decisions, or the
claims history of the airline industry as well as that of AIRLINE, and, based on
the written recommendations of such

                                       62
<Page>

consultant, and in consultation with AIRLINE, to reasonably adjust the insurance
coverages and limits required herein but not more often than every twenty-four
months.

SECTION 1102.  DAMAGE TO PREMISES

     (A) MINOR DAMAGE. If any part of the Leased Premises, or adjacent
facilities directly and substantially affecting the use of the Leased Premises,
shall be partially damaged by fire or other casualty, but said circumstances do
not render the Leased Premises untenantable as determined by the AUTHORITY, the
same shall be repaired to usable condition with due diligence by the AUTHORITY
as provided in this Section 1102.

     (B) SUBSTANTIAL DAMAGE. If any part of the Leased Premises, or adjacent
facilities directly and substantially affecting the use of the Leased Premises,
shall be so extensively damaged by fire, or other casualty, as to render any
portion of said Leased Premises untenantable but capable of being repaired, as
determined by the AUTHORITY, the same shall be repaired to usable condition with
due diligence by the AUTHORITY as provided in this Section 1102. In such case,
the rentals payable hereunder with respect to affected Leased Premises shall be
paid up to the time of such damage and shall thereafter be abated ratably in the
proportion that the part of the urea rendered untenantable bears to total Leased
Premises of the same category and area. Such abatement in rent will continue
until such time as such affected Leased Premises shall be restored adequately
for AIRLINE's use. The AUTHORITY shall use its best efforts to provide alternate
facilities to continue AIRLINE's operation while repair, reconstruction, or
replacement is being completed, at a rental rate not to exceed that provided in
this Agreement for comparable space provided that AIRLINE's rental costs shall
not increase as a result of any such alternate facilities unless AIRLINE
requests additional space and/or space replacement of a classification at higher
rental rates concurrent with such reassignment to alternate facilities.

     (C) TOTAL DAMAGE.

     (i) If any part of the Leased Premises, or adjacent facilities directly and
     substantially affecting the use of the Leased Premises, shall be damaged by
     fire or other casualty, and is so extensively damaged as to render any
     portion of said Leased Premises incapable of being repaired, as determined
     by the AUTHORITY, the AUTHORITY shall notify AIRLINE as soon as practicable
     under the circumstances after the date of such damage of its decision
     whether to reconstruct or replace said space. However, the AUTHORITY shall
     be under no obligation to replace or reconstruct such premises. The rentals
     payable hereunder with respect to affected Leased Premises shall be paid up
     to the time of such damage and thereafter shall cease until such time as
     replacement or reconstructed space shall be available for use by AIRLINE.

     (ii) In the event the AUTHORITY elects to reconstruct or replace affected
     Leased Premises, the AUTHORITY shall use its best efforts to provide
     alternate facilities to continue AIRLINE's operation while repair,
     reconstruction, or replacement is being completed, at a rental rate not to
     exceed that provided in this Agreement for comparable space. However, if
     such damaged space shall not have been replaced or reconstructed, or the
     AUTHORITY is not diligently pursuing such replacement or reconstruction,
     within six months after the date of such damage or destruction, AIRLINE
     shall have the right, upon giving the

                                       63
<Page>

     AUTHORITY 30 days advance written notice, to delete the affected Leased
     Premises from this Agreement, but this Agreement shall remain in effect
     with respect to the remainder of said Leased Promises, unless such damaged
     or destroyed premises prevent AIRLINE from operating its Air Transportation
     Business at the AIRPORT.

     (iii) In the event the AUTHORITY elects not to reconstruct or replace
     affected Leased Premises, the AUTHORITY shall meet and consult with AIRLINE
     on ways to permanently provide AIRLINE with adequate replacement space for
     affected Leased Premises.  AIRLINE shall have the right, upon giving the
     AUTHORITY 30 days advance written notice, to delete the affected Leased
     Premises from this Agreement, but this Agreement shall remain in full force
     and effect with respect to the remainder of said Leased Premises, unless
     the loss of such premises prevents AIRLINE from operating its Air
     Transportation Business at the AIRPORT.

     (D) SCOPE OF RESTORATION OF PREMISES.

     (i) The AUTHORITY's obligations to repair, reconstruct, or replace affected
     premises under the provisions of this Section shall in any event be limited
     to using due diligence and best efforts to restore affected Leased Premises
     to substantially the same condition that existed prior to any such damage
     and shall further be limited to the extent of insurance proceeds available
     to the AUTHORITY for such repair, reconstruction, or replacement. AIRLINE
     agrees that if the AUTHORITY elects to repair, reconstruct, or replace
     affected premises as provided in this Section, then AIRLINE shall proceed
     with reasonable diligence and at its sole cost and expense to repair,
     reconstruct, or replace its signs, fixtures, furnishings, equipment, and
     other items provided or installed by AIRLINE in or about the Leased
     Premises in a manner and in a condition at least equal to that which
     existed prior to said damage or destruction.

     (ii) In lieu of the AUTHORITY's repair, reconstruction, or replacement of
     the affected premises, as provided in this Section, if AIRLINE requests to
     perform said function with respect to damage under Sections 1102(A) and
     1102(B), the AUTHORITY may in its sole discretion, allow AIRLINE to perform
     such work. AIRLINE shall not be performing such work as an agent or
     contractor of the AUTHORITY. Any such work by AIRLINE must be done in
     accordance with the requirements of Section 801. The AUTHORITY shall
     reimburse AIRLINE for the cost of such work performed by AIRLINE.

     (E) DAMAGE FROM AIRLINE NEGLIGENCE. Notwithstanding the provisions of this
Section, in the event that due to the negligent or willful acts of AIRLINE, its
agents, servants, or employees, or those under its control, Leased Premises
shall be damaged or destroyed by fire, casualty, or otherwise, there shall be no
abatement of rent during the restoration or replacement of said Leased Premises
and AIRLINE shall have no option to delete the affected Leased Premises from
this Agreement under the provisions of this Section. To the extent that the
costs of repairs pursuant to this section shall exceed the amount of any
insurance proceeds payable to the AUTHORITY by reason of such damage or
destruction, AIRLINE shall pay the amount of such additional costs to the
AUTHORITY.

SECTION 1103.  INDEMNIFICATION

     (A) AIRLINE agrees to defend, indemnify, and hold harmless the AUTHORITY,
its past, present and future directors, officers, employees, and agents from and
against any and all loss, liability, penalties, damages of whatever nature,
causes of action, suits, claims, demands, judgments, injunctive relief, awards
and settlements, costs and expenses, including, without limitation, payments of
claims of liability resulting from any injury or death of any person or damage
to or destruction of any property, arising out of or in connection with the
conduct of AIRLINE's Air Transportation Business or the AIRLINE's use of its
Leased Premises or other areas or facilities at the AIRPORT by AIRLINE, its
agents, employees, business invitees, contractors, or subcontractors, including,
but not limited to:

     (i) The acts or omissions of AIRLINE, its agents, employees, business
     invitees, contractors, or subcontractors;

     (ii) AIRLINE's use or occupancy of the AIRPORT and the Leased Premises;

     (iii) The violation by AIRLINE in the conduct of AIRLINE's Air
     Transportation Business or its use of its Leased Premises or other areas or
     facilities at the AIRPORT of any provision, warranty, covenant, or
     condition of this Agreement, of any applicable, law, ordinance, regulation,
     or court order affecting the AIRPORT, including the AUTHORITY's Rules and
     Regulations; and

     (iv) Violations or alleged violations of any federal or state laws as a
     result of any actions taken by AIRLINE, pursuant to this Agreement.

     AIRLINE will, at its own cost and expense, defend all such claims, demands
and suits, whether frivolous or not.

     (B) Without limiting the foregoing, AIRLINE also agrees to defend,
indemnify, and hold harmless the AUTHORITY, its past, present and future
directors, officers, agents, and employees:

     (i) From and against any and all claims or liability for compensation under
     any workers' compensation statute arising out of injuries sustained by any
     employee of AIRLINE. AIRLINE shall require by contract that its licensees
     and contractors to maintain in effect at all times workers' compensation
     insurance as required by law;

     (ii) From, and to assume all liability for, and to pay, all applicable
     taxes and assessments for payment of which the AUTHORITY may become liable
     and which by law may be levied or assessed on the Leased Premises, or which
     arise out of the operations of AIRLINE or by reason of AIRLINE's occupancy
     of its Leased Premises except for any taxes or assessments based on the
     gross or net income or gross or net receipts of the AUTHORITY that are not
     allocable to airline-related receipts. However, AIRLINE may, at its own
     risk, cost, and expense, and at no cost to the AUTHORITY, contest, by
     appropriate judicial or

                                       65
<Page>

     administrative proceedings, the applicability or the legal or
     constitutional validity of any such tax or assessment, and the AUTHORITY
     will, to the extent permitted by law, execute such documents as are
     necessary to permit AIRLINE to contest or appeal the same.  AIRLINE shall
     be responsible for obtaining bills for all of said taxes and assessments
     directly from the taxing authority and shall promptly deliver to the
     AUTHORITY, upon request, copies of receipts of payment.  In the event the
     AUTHORITY receives any tax billings, it will forward said billings to
     AIRLINE; and

     (iii) From and against any and all suits, claims, actions, or proceedings
     alleging a taking of property or interests in property without just
     compensation, trespass, nuisance, property damage, personal injury or
     similar claims, actions, proceedings or suits based upon the environmental
     impacts resulting from AIRLINE'S use of the AIRPORT for the landing and
     taking-off of aircraft including noise, smoke, or vibration.

     (C) AIRLINE shall defend, indemnify, and hold the AUTHORITY, and its
agents, officers, and employees, completely harmless from and against any claim,
suit, demand, action, liability, loss, damage, judgment, or fine, and all costs
and expenses of whatever kind or nature (including, but not limited to,
reasonable and actual attorney's fees, court costs, investigation expenses, and
expert fees) associated therewith in any way arising from or based upon the
violation of any federal, state, or municipal laws, statutes, resolutions, or
regulations by AIRLINE, its agents, employees, contractors, or tenants, in
conjunction with AIRLINE'S use and/or occupancy of the Leased Premises or its
operations at the AIRPORT.

     (D) AIRLINE further agrees that if a prohibited incursion into the air
operations area occurs, or if the Airfield Operations Area or sterile area
security is breached, by or due to the negligence or willful act or omission of
any of AIRLINE'S employees, agents, contractors, and such incursion or breach
results in a civil penalty action against the AUTHORITY, AIRLINE shall assume
the defense of any such action and be responsible for any civil penalty or
settlement amount required to be paid by the AUTHORITY as a result of such
incursion or breach. The AUTHORITY shall notify AIRLINE of any allegation,
investigation, or proposed or actual civil penalty sought for such incursion or
breach. Civil penalties and settlement and associated expenses reimbursable
under this paragraph include but are not limited to those paid or incurred as a
result of violation of FAA Federal Aviation Regulation Part 107, "Airport
Security," FAA Federal Aviation Regulation Part 108, "Airplane Operator
Security," and FAA Federal Aviation Regulation Part 139, "Certification and
Operations: Land Airports Serving Certain Air Carriers."

     (E) AIRLINE'S obligation to defend and indemnify past directors, officers
and employees of the AUTHORITY shall apply to such persons only for such periods
during which said directors, officers and employees held their office or
position with the AUTHORITY.

     (F) The AUTHORITY shall promptly notify AIRLINE of each claim, action,
proceeding, or suit in respect of which indemnity may be sought by the AUTHORITY
against AIRLINE hereunder, setting forth the particulars of such claim, action,
proceeding or suit, and shall furnish AIRLINE with a copy of all judicial
filings and legal process and any correspondence received by the AUTHORITY
related thereto.

                                       66
<Page>

     (G) The duty to defend, indemnify, hold harmless, and reimburse shall apply
to any claim, demands, or suits made against the AUTHORITY, whether or not
meritorious for which AIRLINE is responsible pursuant to Section 1103. Provided,
however, that upon the filing by anyone of a claim with the AUTHORITY for
damages arising out of incidents for which AIRLINE herein agrees to indemnify
and hold the AUTHORITY harmless, the AUTHORITY shall promptly notify AIRLINE of
such claim and, in the event that AIRLINE does not settle or compromise such
claim, then AIRLINE shall undertake the legal defense of such claim both on
behalf of AIRLINE and on behalf of the AUTHORITY. It is specifically agreed,
however, that the AUTHORITY, at its option and at its own expense, may
participate in the legal defense of such claim. Any final judgment rendered
against the AUTHORITY for any cause for which AIRLINE is liable hereunder shall
be conclusive against AIRLINE as to amount upon the expiration of the time for
appeal therefrom. In the event the AUTHORITY shall fail to give AIRLINE notice
of any such demand, notice, summons, or other process received by the AUTHORITY
and such failure to give notice shall result in prejudice to AIRLINE in the
defense of any action or legal proceeding contemplated herein, such failure or
delay shall release AIRLINE of its liability as set forth in this paragraph
insofar as only the particular claim or legal proceeding is concerned, and only
to the extent of such prejudice. Nothing in this Article XI shall be deemed a
change or modification in any manner whatsoever of the method or conditions of
preserving, asserting, or enforcing arty claim of legal liability against the
AUTHORITY. This Section 1103 shall not be construed as a waiver of the
AUTHORITY's immunity.

     (H) The AUTHORITY, at its own expense except as otherwise provided herein,
shall be invited to attend and participate in all meetings (including those
related to settlement) and to appear and participate in all judicial proceedings
and to the extent of its interests, approve, in writing, the terms of any
settlement related to any claim, action, proceeding or suit set forth in (his
Section.

     (I) Notwithstanding the provisions of this Section, AIRLINE shall have no
obligation to indemnify the AUTHORITY for any amounts to be paid in connection
with losses, liabilities, penalties, damages of whatever nature, causes of
action, suits, claims, demands, injunctive relief, judgments, awards and
settlements to the extent such are the result of the AUTHORITY's negligence or
willful misconduct.

     (J) This Section shall survive the expiration or early termination of this
Agreement. AIRLINE understands and agrees that any insurance protection
furnished by AIRLINE pursuant to Section 1101 shall in no way limit AIRLINE's
responsibility to indemnify and hold harmless the AUTHORITY under the provisions
of this Agreement.

SECTION 1104.  AUTHORITY NOT LIABLE

     The AUTHORITY shall not in any event be liable for any acts or omissions of
AIRLINE, its officers, agents, employees, invitees, and independent contractors,
or for any conditions resulting from the operations or activities of any such
lessee, tenant, or concessionaire, AIRLINE officers, employees, invitees, or
independent contractors, or for any conditions resulting from the operations or
activities of AIRLINE's officers, agents, employees, invitees, or independent
contractors either to AIRLINE or to any other person.  The AUTHORITY shall not
be liable for AIRLINE's failure to perform any of the obligations under this
Agreement or for any delay in the performance thereof.  AIRLINE expressly agrees
that the AUTHORITY shall not be liable to AIRLINE, for bodily injury or for any
loss or damage to real or personal property occasioned by flood, fire,
earthquake, lightning, windstorm, hail, explosion, riot, strike, civil
commotion, smoke,

                                       67
<Page>

vandalism, malicious mischief, or acts of civil authority and not caused by the
negligence or willful acts or omissions of the AUTHORITY.

                                  ARTICLE XII
                       MERGERS, ASSIGNMENT AND SUBLETTING

SECTION 1201.  AIRLINE MERGERS AND CONSOLIDATIONS

     If AIRLINE consolidates with or merges into another corporation or permits
one or more other corporations to consolidate with or merge into it, or
transfers or conveys all or substantially all of its property, assets and
licenses to another corporation, the corporation resulting from or surviving
such merger (if other than AIRLINE) or consolidation or the corporation to which
such transfer or conveyance is made shall (a) expressly assume in writing and
agree to perform all of AIRLINE's obligations hereunder, (h) he qualified to do
business in the State of Ohio, and (c) if such corporation shall not be
organized and existing under the laws of the United States of America or any
state or territory thereof or the District of Columbia, furnish to the AUTHORITY
an irrevocable consent to service of process in, and to the jurisdiction of the
courts of, the State of Ohio with respect to any action or suit, in law or at
equity, brought by the AUTHORITY to enforce this Agreement.  If AIRLINE is the
surviving corporation in such a merger, the express assumption referred to in
the preceding sentence shall not be required.

SECTION 1202.  ASSIGNMENT OR SUBLETTING

     AIRLINE shall not assign, transfer, convey, sell, mortgage, pledge, or
encumber (hereinafter collectively referred to as "Assignment") or sublet its
Leased Premises without the advance approval of the AUTHORITY.  If AIRLINE fails
to obtain advance approval of any such assignment or sublease or the AUTHORITY,
in addition to the rights and remedies set forth in Article XIII, shall have the
right to refuse to recognize such agreement, and the assignee or sublessee shall
acquire no interest in this Agreement or any rights to use the Leased Premises.

SECTION 1203.  AUTHORITY APPROVAL OF ASSIGNMENTS

     (A) Without in any manner limiting AUTHORITY's general right to approve
assignments, it shall not be unreasonable for the AUTHORITY to disapprove or
condition an assignment of AIRLINE's Leased Premises on any or all of the
following circumstances, among others:

     (i) The assignment is for less than the full remainder of the term of this
     Agreement.

     (ii) The assignment does not require the assignee to accept and comply with
     all provisions of the Agreement, including but not limited to accepting
     Signatory Airline status.

     (B) Notwithstanding the foregoing, this Section shall not be interpreted to
preclude or to require the AUTHORITY's approval of the assignment of this
Agreement and AIRLINE's rights and obligations hereunder to a parent,
subsidiary, or merged company if such parent, subsidiary, or merged company
conducts an Air Transportation Business at the AIRPORT and assumes all rights
and obligations hereunder. Written notice of such assumption shall be provided
by the parent, subsidiary, or merged company 30 days prior to the effective date
of such assignment.

SECTION 1204.  AUTHORITY APPROVAL OF SUBLEASES

     (A) Without in any manner limiting AUTHORITY's general right to approve
subleases, it shall not be unreasonable for the AUTHORITY to disapprove or
condition a sublease of AIRLINE's Leased Premises on any or all of the following
circumstances, among others:

     (i) If a Signatory Airline, including a Signatory Airline which is not
     leasing space directly from the AUTHORITY because of the unavailability of
     such space, is, in the determination of the AUTHORITY, in need of tile
     Leased Premises proposed to be subleased; provided, however, that such
     Signatory Airline is willing to take such Leased Premises on substantially
     the same terms and conditions as proposed in the sublease and is willing to
     provide AIRLINE with a reasonable security deposit not to exceed 3 month's
     rentals, fees, and charges

     (ii) If the AUTHORITY determines that there is available space and/or
     Passenger Holdrooms for lease directly from the AUTHORITY by the proposed
     sublessee or if the sublease does not contain a provision which permits it
     to be terminated upon notice from the AUTHORITY to the parties thereto of
     the availability of AUTHORITY controlled space, provided that this
     paragraph shall not apply to Airlines which are code shares.

SECTION 1205.  METHOD OF OBTAINING APPROVAL

     AIRLINE, when requesting an approval of an assignment or sublease under
Section 1202, shall include with its request a copy of the proposed agreement,
if prepared, or a detailed summary of the material terms and conditions to be
contained in such agreement. Any proposed agreement or detailed summary thereof
shall provide the following information: (a) the Leased Premises to be assigned
or sublet; (b) the terms; (c) if a sublease, the rentals and fees to be charged;
and (d) all material terms and conditions of the assignment or sublease the
AUTHORITY may reasonably require. If approved, AIRLINE shall submit a fully
executed copy of such agreement to the AUTHORITY within 30 days after the
commencement of the assignment or sublease.

SECTION 1206.  ADMINISTRATIVE CHARGE

     In the event AIRLINE is authorized by the AUTHORITY to sublease any portion
of its Leased Premises, AIRLINE may charge such sublessee, in addition to a
reasonable charge for any services and AIRLINE-owned property provided by

rentals not to exceed one hundred fifteen percent (115%) of AIRLINE's rentals
for such portion of the Leased Premises.

SECTION 1207.  AIRLINE TO REMAIN LIABLE

     AIRLINE shall remain fully and primarily liable during the term of this
Agreement for the payment of all of the rentals due and payable to the

other obligations hereunder, unless otherwise agreed to by the AUTHORITY.

SECTION 1302.  TERMINATION BY THE AUTHORITY

     (A) Whenever an Event of Default has occurred, the AUTHORITY may, at its
option, immediately and without further notice of such Event of Default:

     (i) Terminate this Agreement and the lettings, licenses, and other rights
     of AIRLINE hereunder, without discharging any of AIRLINE's obligations
     hereunder and, at the AUTHORITY's further option, exclude AIRLINE from its
     Leased Premises. In the event AIRLINE uses, occupies, or fails to surrender
     or remove its property from its Leased Premises, or any portion thereof,
     without the

                                       72
<Page>

     written consent of the AUTHORITY after this Agreement has been terminated
     or expires, AIRLINE may be deemed a tenant at sufferance during the period
     of such use or failure and, in such event, AIRLINE shall pay the rate for
     rentals, fees, and charges established by the AUTHORITY for Airlines which
     are not Signatory Airlines during such period.  In such event, the
     AUTHORITY shall have, in addition to whatever other rights are available to
     the AUTHORITY, the right to all remedies provided under applicable laws,
     and reasonable costs, disbursements, and attorney fees including
     consequential damages incurred as a result of the holdover.

     (ii) Without terminating this Agreement, exclude AIRLINE from its Leased
     Premises and use its best efforts to lease such Leased Premises to another
     airline with any rentals received credited to the amounts owed by AIRLINE,
     minus a fifteen percent (15%) administrative fee of all sublease rentals
     received, holding AIRLINE liable for all Rentals, Fees, and Charges and
     other payments due hereunder up to the effective date of such leasing and
     for the excess, if any, of the Rentals, Fees, and Charges and other amounts
     payable by AIRLINE under this Agreement for the remainder of the term of
     this Agreement over the rentals and other amounts which are paid by such
     new airline under such new agreement.

     (iii)  In addition, the AUTHORITY may, from time to time, take whatever
     action at law or in equity appears necessary or desirable to collect
     Rentals, Fees, and Charges and any other amounts payable by AIRLINE
     hereunder then due and thereafter to become due, and to enforce the
     performance and observance of any obligation, agreement or covenant of
     AIRLINE under this Agreement.

     (B) In the event of an Event of Default, the AUTHORITY may exercise any and
all of the rights provided to it in this Section 1302 irrespective of any

rights and remedies given to the AUTHORITY by law, shall be cumulative and
concurrent. No termination of this Agreement or the taking or recovering of the
Leased Premises shall deprive the AUTHORITY of any of the AUTHORITY's remedies
or actions against AIRLINE for rentals, fees, and charges or for damages or for
the breach of any covenant herein contained, nor shall the bringing of any
action for rentals, fees, and charges or breach of covenant, or the resort to
any other remedy herein provided for the recovery of rentals, fees, and charges
be construed as a waiver of the right to obtain possession of the Leased
Premises.

     (E) In no event shall this Agreement or any rights or privileges hereunder
be an asset of AIRLINE under any bankruptcy, insolvency, or reorganization
proceedings.

                                       73

SECTION 1303.  CHANGE OF LEASE TERM

     (A) Notwithstanding the provisions of Section 201, automatically and
immediately upon the occurrence of an Event of Default described in Section 1301
(H), (I), (J), (K), (L) or (M), the term of this Agreement shall convert to
month-to-month, commencing on the date of the automatic conversion and in
addition to its rights under Article XIII either party shall have the right to
terminate the Agreement upon 30 days written notice from the AUTHORITY to
AIRLINE, or from AIRLINE to the AUTHORITY.

     (B) The conversion of the term of this Agreement pursuant to this Section
1303 shall not discharge any of AIRLINE's obligations hereunder nor affect any
of the AUTHORITY's other remedies set forth herein.

SECTION 1304.  TERMINATION BY AIRLINE

     (A) At any time that AIRLINE is not in default hereunder, AIRLINE may
terminate this Agreement and its obligations hereunder to the extent set forth
below, at AIRLINE's option, prior to the scheduled expiration date set forth in
Section 201, by giving the AUTHORITY 60 days' advance written notice by
registered or certified mail upon or after the happening and during the
continuance of any of the following events:

     (i) Any action of the Federal Aviation Administration or any other federal,
     state, county, or municipal governmental agency refusing to permit AIRLINE
     to operate into, from, or through the AIRPORT such aircraft (licensed for
     use in scheduled air transportation) as AIRLINE has previously operated
     regularly thereon, and the remaining in force of such refusal for a period
     of at least 60 days; provided however, that this provision shall not apply
     if occasioned by AIRLINE's failure to comply with airworthiness or noise
     standards for such aircraft as promulgated by FAA;

     (ii) Any failure by the AUTHORITY to keep, perform and observe any material
     promise, covenant, or other provision of this Agreement for a period of 30
     days after written notice specifying such failure and requesting that it be
     remedied is given to the AUTHORITY by AIRLINE; provided, however, that any
     such failure which can be cured, but which cannot with due diligence be
     cured within such 30 day period, shall not give rise to AIRLINE's right to
     terminate this Agreement if corrective action is instituted by the
     AUTHORITY within such 30 day period and diligently pursued until the
     failure is corrected; or

     (iii) AIRLINE is prevented from conducting its Air Transportation Business
     at the AIRPORT for a period in excess of 60 consecutive days for any reason
     other than causes directly controlled by AIRLINE.

                             SURRENDER OF PREMISES

SECTION 1401. SURRENDER OF PREMISES

     (A) SURRENDER OF PREMISES. AIRLINE covenants and agrees that on expiration
of the term of this Agreement, or earlier termination as hereinafter provided,
or on reassignment or reallocation of the Leased Premises as provided herein, it
will peaceably surrender possession of the Leased Premises, and other space made
available to AIRLINE hereunder in a clean, sanitary, and good condition,
reasonable wear and tear taking into account maintenance required to be done by
AIRLINE, and acts of God, fire, and other casualties excepted, and the AUTHORITY
shall have the right to take possession of said Leased Premises and other space
made available to AIRLINE hereunder. The AUTHORITY shall not be required to give
notice to quit possession at the expiration date of the term of this Agreement.

     (B) REMOVAL OF PERSONAL PROPERTY. Provided AIRLINE is not in default for
payment of Rentals, Fees, Charges, PFCs, or any other payment due hereunder,
AIRLINE shall have the right, on expiration or early termination of this
Agreement and within 30 days thereafter, to remove or dispose of all trade
fixtures and equipment and other personal property installed or placed by
AIRLINE, in, on, or about the AIRPORT; provided, however, that the AUTHORITY
reserves the right to purchase from AIRLINE its ticket counter inserts and
baggage conveyors at AIRLINE's netbook value of such inserts and conveyors at
fair market value as of the date of such expiration or early termination.
AIRLINE shall not be entitled to remove non-trade fixtures without the advance
written consent of the AUTHORITY.

     (C) REMOVAL DAMAGES. In the event AIRLINE removes its trade fixtures and
equipment and other personal property and/or is allowed to remove its non-trade
fixtures and removes such fixtures, AIRLINE shall repair any damage caused by
such removal. Removal shall be at AIRLINE's expense. Notwithstanding the above,
consideration shall be given to the intended long-term use of the Premises and
in the event it is determined that such Premises shall not be maintained for a
period warranting the repairs indicated above, AIRLINE's requirement to perform
such may be reduced or eliminated by AUTHORITY. In the event the Leased Premises
are yielded or delivered to the AUTHORITY in need of repair, reconditioning, or
restoration to its original condition (reasonable wear and tear taking into
account maintenance required to be done by AIRLINE excepted), after reasonable
notice to AIRLINE, the AUTHORITY shall repair or recondition said excepted
Leased Premises and the cost thereof will be invoiced to AIRLINE as provided in
Section 704. The AUTHORITY shall determine the condition of the Leased Premises
at the termination of this Agreement by expiration or otherwise.

     (D) OWNERSHIP OF FIXTURES NOT REMOVED. In the event AIRLINE fails to remove
its property, in addition to whatever other rights are available to the
AUTHORITY, with prior notification of AIRLINE the AUTHORITY shall have the
options of (a) removing, selling, or storing AIRLINE property at AIRLINE's
expense, or (b) taking title to AIRLINE property in lieu of removal on behalf of
AIRLINE. In the event the AUTHORITY takes title to such property or otherwise
disposes of the property, the AUTHORITY shall be entitled to all proceeds of
sale of such AIRLINE property as liquidated damages for the breach of this
covenant to remove.

                            MISCELLANEOUS PROVISIONS

SECTION 1501. RELATIONSHIP OF PARTIES

     Nothing herein contained is intended or shall be construed to in any
respect create or establish any relationship other than that of lessor and
lessee, and nothing herein shall be construed to establish any partnership,
joint venture or association or to make AIRLINE the general representative or
agent of the AUTHORITY for any purpose whatsoever.

SECTION 1502. AMENDMENT

     Except as otherwise expressly provided herein, this Agreement, including

     (A) This Agreement and all rights granted to AIRLINE hereunder, are
expressly subordinated and subject to the lien and provisions of the pledges,
transfer, hypothecation, or assignment made by the AUTHORITY in any Trust
Indenture executed by the AUTHORITY to issue Bonds. The AUTHORITY expressly
reserves the right to make such pledges and grant such liens and enter into
covenants as it may deem necessary or desirable to secure and provide for the
payment of Bonds, including the creation of reserves therefor, provided that the
AUTHORITY shall not take any actions that would he inconsistent with the term
and conditions of this Agreement.

     (B) AIRLINE understands that the AUTHORITY is and will be the issuer of
Bonds. With respect to Bonds that may be issued in the future, the interest on
which is intended to be excludable from gross income from the holders of such
Bonds for Federal income tax purposes under the Internal Revenue Code of 1986,
AIRLINE agrees that it will not act, or fail to act (and will immediately cease
and desist from any action, or failure to act) with respect to the use of the
Leased Premises, if the act or failure to act may cause the AUTHORITY to be in
noncompliance with the provisions of the Internal Revenue Code of 1986 as they
now exist or may be amended, supplemented, or replaced, or the regulations or
rulings issued thereunder, nor will AIRLINE take, or persist in, any action or
omission which may cause the interest on the tax-exempt Bonds either (a) not to
be excludable from the gross income of the holders thereof for Federal income
tax purposes; or (b) to become subject to the alternative minimum tax (the AMT)
for Federal income tax purposes.

SECTION 1504. CERTIFICATE IN CONNECTION WITH ISSUANCE OF BONDS

     AIRLINE agrees that in connection with any issuance of Bonds by the
AUTHORITY, upon not less than 30 days prior written request by the AUTHORITY,
AIRLINE will deliver to the AUTHORITY a statement in writing certifying:

     (i) That this Agreement is unmodified and in full force and effect (or if
     there have been modifications, a description of such modifications and that
     the Agreement as modified is in full force and effect);

                                       76
<Page>

     (ii) That to the AIRLINE's knowledge the AUTHORITY is not in default under
     any provision of this Agreement, or, if in default, the nature thereof in
     detail; and

     (iii) Such further matters as may be reasonably requested by the AUTHORITY,
     it being intended that any such statement may be relied upon by the parties
     involved in such issuance of Bonds.

SECTION 1505. NO THIRD PARTY BENEFICIARIES

     This Agreement is for the sole benefit of the parties hereto and their
permitted assigns and nothing herein expressed or implied shall give or be

hereunder.

SECTION 1508. SURVIVAL OF WARRANTIES

     All warranties and covenants set forth in this Agreement shall survive the
execution and performance of this Agreement.

SECTION 1509. QUIET ENJOYMENT

     The AUTHORITY agrees that, upon payment of all amounts due hereunder and
performance of the covenants and agreements on the part of AIRLINE to be
performed hereunder, the AUTHORITY shall not act or fail to act, except as
otherwise provided by this Agreement, in a manner that will prevent AIRLINE from
peaceably having and, in accordance with the terms hereof, enjoying the Leased
Premises and all rights, licenses, services, and privileges of the AIRPORT and
its appurtenances and facilities granted herein.

SECTION 1510. NO PERSONAL LIABILITY

     (A) The AUTHORITY shall not be liable for any acts or omissions of any
airline or any condition resulting from the operations or activities of tenants
or their representatives.

the operation of the AIRPORT by the United States of America.

courts and waives personal service of any and all process upon the AIRLINE
herein, and consents that all such service of process shall be made by certified
mail, return receipt requested, directed to AIRLINE at the address herein
stated, and service so made shall be completed 7 days after the same shall have

     In the event any covenant, condition, or provision herein is held to be

covenant, condition, or provision shall be deemed amended to conform to
applicable laws so as to be valid or enforceable or, if it cannot be so amended
without materially altering the intention of the parties, it shall be stricken.

SECTION 1517. NO WAIVER

     No provision of this Agreement shall be deemed to have been waived by

SECTION 1521. TIMING

     The parties expressly agree that time is of the essence in this Agreement.

SECTION 1522. REPRESENTATIVES

     The AUTHORITY and AIRLINE shall each designate a representative who, except
as otherwise provided hereunder, shall be authorized to act for the AUTHORITY
and AIRLINE, respectively, with respect to any actions to be taken by either of

to the other party.

SECTION 1523. APPROVALS

     (A) Whenever in this Agreement any approval is required from AIRLINE, such
decision shall be promptly rendered and shall not be unreasonably withheld or
conditioned. No disapproval shall be valid if such disapproval constitutes an

such matters.

     (B) Wherever in this Agreement the approval of the AUTHORITY is required,
such approval may be given by the Executive Director, shall be promptly rendered
and shall not be unreasonably withheld except as otherwise expressly provided
herein.

     (C) In all instances in this Agreement where consent or approval of one
party is required for an action by the other party, such consent shall be in
writing unless otherwise agreed by the parties.

SECTION 1524. PROHIBITION AGAINST EXCLUSIVE RIGHTS

     It is hereby specifically understood and agreed that nothing herein
contained shall be construed to grant or authorize the granting of an exclusive
right to provide aeronautical services to the public as prohibited by
Section 308(a) of the Federal Aviation Act of 1958, as amended, and the
AUTHORITY reserves the right to grant to others the privileges and right of
conducting any or all activities of an aeronautical nature.

     BINDING EFFECT. The terms, conditions, and covenants of this Agreement

Permittee shall not in any manner prejudice or diminish the rights of Signature
as set forth in Article 25. Imposition of a late payment fee is solely at
Signature's option and failure by Signature to exercise this option does not
waive Signature's right to exercise this right at a future date.

prevailing land rents and/or concession fees applicable to Signature's leasehold

certificates or other evidence of insurance from the Permittee shall not be
deemed a waiver by Signature. Non-conforming insurance shall not relieve

Nonfulfillment of the insurance conditions by Permittee hereunder may constitute
a material breach of this Permit and Signature retains the right to suspend the
Permit until proper evidence of insurance is provided or, in the continued
absence of such insurance evidence, terminate this Permit, in Signature's sole
discretion.

b) increase the rate of insurance on the Space or any property located therein.
If, by reason of the failure of Permittee to comply with the provisions of this
Permit, the insurance rate shall at any time be higher than it otherwise would

demand, for that part of all premiums for any insurance coverage that shall have
been charged because of such actions by Permittee.

maintain, at Signature's expense, liability insurance, fire insurance with
extended coverage and other insurance on Signature's leased premises with

provided, however, that should Signature initiate corrective action in response
to a notification of default within thirty (30) days and the nature of the
corrective action required precludes Signature from rectifying such default

term, covenant, agreement, provision, condition or limitation of this Permit or
to exercise any right or remedy consequent upon a breach thereof, and no

such breach or application of the security deposit in light of any breach, shall
constitute a waiver of any such breach or of any such term, covenant, agreement,
provision, condition, limitation, right or remedy. No term, covenant, agreement,
provision, condition or limitation of this Permit to be kept, observed or
performed by Signature or by Permittee, and no breach thereof, shall be waived,
