         cost and expense to perform the construction work. All construction
         work, including workmanship and materials, shall be of first class
         quality. The User shall re-do, replace or reconstruct at its own cost
         and expense, any construction work not done in accordance with the
         approved plans and specifications, the provisions of this Section or
         any further requirements of Pan American made in accordance with this
         Agreement.

3.6.3    Prior to entering into a contract for any part of the construction
         work, the User shall submit to Pan American for its approval the names
         of the contractors to whom the User proposes to award said contracts.
         Pan American shall have the right to disapprove any contractor who may
         be unacceptable to it. The User shall include in all such contracts
         such provisions and conditions as may be required by Pan American
         including, without limitation thereto, the provisions set forth in
         Exhibit B attached hereto and hereby made a part hereof.

3.6.4    The User shall furnish or require its architect to furnish a resident
         engineer during the construction period as Pan American may require.
         The User shall require certification by a licensed engineer of all pile
         driving data and of all controlled concrete work and such other
         certifications as may be requested by Pan American from time to time.

3.6.5    The User agrees to be solely responsible for any plans and
         specifications used by it and for any loss or damages resulting from
         the use thereof, notwithstanding the same have been approved by Pan
         American and the Port Authority notwithstanding the incorporation
         therein of Pan American or Port Authority recommendations or
         requirements. Notwithstanding the requirements for approval by Pan
         American of the contracts to be entered into by the User on the
         incorporation therein of Pan American requirements or recommendations,
         and notwithstanding any rights Pan American may have reserved to itself
         hereunder, Pan American shall have no liabilities or obligations of any
         kind to any contractors engaged by the User or for any other matter in
         connection therewith

                                       5

         and the User hereby releases and discharges Pan American, its
         Directors, officers, representatives and employees of and from any and
         all liability, claims for damages or losses of any kind, whether legal
         or equitable, or from any action or cause of action arising or alleged
         to arise out of the performance of any construction work pursuant to
         the contracts between the User and its contractors. Any warranties
         contained in any construction contract entered into by the User for the
         performance of the construction work hereunder shall be for the benefit
         of Pan American and the Port Authority as well as the User.

3.6.6    Pan American shall have the right, through its duly designated
         representatives, to inspect the construction work and the plans and
         specifications thereof, at any and all times during the progress
         thereof and from time to time, in its discretion, to take samples and
         perform testing on any part of the construction work.

3.6.7    The User agrees that it shall deliver to Pan American "as-built"
         drawings (capable of being reproduced) of the construction work and
         shall during the term of this Agreement keep said drawings current
         showing thereon any changes or modifications which may be made. (No
         changes or modifications to be made without Pan American's consent.)

3.6.8    The User shall, if requested by Pan American, take all reasonable
         measures to prevent erosion of the soil and the blowing of sand and
         soil during the performance of the construction work, including but not
         limited to the fencing of the space or portion thereof and the covering
         of open areas with asphaltic emulsion or similar materials as Pan
         American may direct.

3.6.9    The User shall pay or cause to be paid all claims lawfully made against
         it by its contractors, subcontractors, materialmen and workmen, and all
         claims lawfully made against it by other third persons arising out of
         or in connection with or because of the performance of the construction
         work, and shall cause its contractors and subcontractors to pay all
         such claims lawfully made against them, provided, however, that nothing
         herein contained shall be construed to limit the right of the User to
         contest any claim of a contractor, subcontractor, materialman, workman
         and/or other person and no such claim shall be considered to be an
         obligation of the User within the meaning of this Section unless and
         until the same shall have been finally adjudicated. The User shall use
         its best efforts to resolve any such claims and shall keep Pan American
         fully informed of its actions with respect thereto. The User shall
         require its construction contractor to furnish a bond for the faithful
         performance of all obligations imposed upon the contractor by the
         construction contract and also for the payment of all lawful claims of
         subcontractors, materialmen and workmen arising out of the performance
         of said construction contract.

3.6.10   The User shall procure and maintain comprehensive general liability
         insurance, including automotive, with a contractual liability
         endorsement covering the obligations assumed by the User pursuant to
         this Section 3 which shall be in addition to all policies of insurance
         otherwise required under the Agreement or

                                       6
<PAGE>

         the User may provide such insurance by requiring each contractor
         engaged by it for the construction work to procure and maintain such
         insurance including such contractual liability endorsement, said
         insurance not to contain any care, custody or control exclusions, any
         exclusions for explosions, collapses or damage to underground utilities
         or facilities, and not to contain any exclusion for bodily injury to or
         sickness, disease or death of any employee of the User or of any of its
         contractors which would conflict with or in any way impair coverage
         under the contractual liability endorsement. Said insurance shall name
         Pan American and the Port Authority as an additional insured and be in
         not less than the following amounts:

         (i)      Bodily Injury Liability:

         The insurance required hereunder shall be maintained in effect during
         the performance of the construction work. A certified copy of each of
         the policies or a certificate or certificates evidencing the existence
         thereof, or binders, shall be delivered to Pan American at least
         fifteen (15) days prior to the commencement of any work. In the event
         any binder is delivered, it shall be replaced within thirty (30) days
         by a certified copy of the policy or a certificate. Each such copy or
         certificate shall contain a valid provision or endorsement that the
         policy may not be cancelled, terminated, changed or modified without
         giving fifteen (15) days' written advance notice thereof to Pan
         American and the Port Authority. The aforesaid insurance shall be
         written by a company or companies approved by Pan American, Pan
         American agreeing not to withhold its approval unreasonably. If at any
         time any of the insurance policies shall be or become unsatisfactory to
         Pan American as to form or substance or if any of the carriers issuing
         such policies shall be or become unsatisfactory to Pan American, the
         User shall promptly

                                       7
<PAGE>

         obtain a new and satisfactory policy in replacement, Pan American
         agreeing not to act unreasonably hereunder.

3.6.11   The User shall prior to the commencement of the construction work at
         all times during the construction work submit to Pan American all
         engineering studies with respect to the construction work and samples
         of construction materials as may be required at any time and from time
         to time by Pan American.

3.6.12   The User shall procure and maintain or cause to be procured and
         maintained Builder's Risk Completed Value Insurance covering the
         construction work during the performance thereof including material
         delivered to the construction site but not attached to the realty. Such
         insurance shall name Pan American, the Port Authority, the User and its
         contractors and subcontractors as additional assureds and such policy
         shall provide that the loss shall be adjusted with and payable to the
         User. Such proceeds shall be used by the User for the repair,
         replacement or rebuilding of the construction work and any excess shall
         be paid over to Pan American. The policies or certificates representing
         this insurance shall be delivered by the User to Pan American prior to
         the commencement of construction and each policy or certificate
         delivered shall bear the endorsement of or be accompanied by evidence
         of payment of the premium thereon and, also, a valid provision
         obligating the insurance company to furnish the Port Authority and Pan
         American fifteen (15) days' advance notice of the cancellation,
         termination, change or modification of the insurance evidenced by said
         policy or certificate. The insurance shall be written by companies
         approved by Pan American, Pan American agreeing not to withhold its
         approval unreasonably. If at any time any of the insurance policies
         shall be or become unsatisfactory to Pan American as to form or
         substance or if any of the carriers issuing such policies shall be or
         become unsatisfactory to Pan American, the User shall promptly obtain a
         new and satisfactory policy in replacement, Pan American agreeing not
         to act unreasonably hereunder.

3.6.13   Nothing contained in this Agreement shall grant or be deemed to grant
         to any contractor, architect, supplier, subcontractor or any other
         person engaged by the User or any of its contractors in the performance
         of any part of the construction work any right of action or claim
         against Pan American, its Directors, officers, agents and employees or
         the Port Authority, its Commissioners, officers, agents and employees
         with respect to any work any of them may do in connection with the
         construction work. Nothing contained herein shall create or be deemed
         to create any relationship between Pan American and any such
         contractor, architect, supplier, subcontractor or any other person
         engaged by the User or any of its contractors in the performance of any
         part of the construction work and neither Pan American nor the Port
         Authority shall be responsible to any of the foregoing for any payments
         due or alleged to be due thereto for any work performed or materials
         purchased in connection with the construction work.

3.6.14   When the construction work is substantially completed and is ready for
         use by the User, the User shall advise Pan American to such effect and
         shall deliver to Pan

                                       8
<PAGE>

         American a certificate by an authorized officer of the User certifying
         that such construction work has been constructed strictly in accordance
         with the approved plans and specifications and the provisions of this
         Agreement and in compliance with all applicable laws, ordinances and
         governmental rules, regulations and orders. Thereafter, such
         construction work will be inspected by Pan American and if the same has
         been completed as specified by the User, a certificate to such effect
         shall be delivered to the User, subject to the condition that all risks
         thereafter with respect to the construction and installation of the
         same and any liability therefor for negligence or other reason shall be
         borne by the User. The User shall not use or permit the use of the
         construction work for the purposes set forth in this Agreement until
         such certificate is received from Pan American. The date of delivery of
         the certificate by Pan American shall constitute the Completion Date
         for the purposes of this Agreement.

3.6.15   The construction work shall be constructed in such a manner that there
         will be at all times a minimum of air pollution, water pollution or any
         other type of pollution and a minimum of noise emanating from, arising
         out of or resulting from the operations of the User under this
         Agreement. Accordingly, and in addition to all other obligations
         imposed on the User under this Agreement and without diminishing,
         limiting, modifying or affecting any of the same, the User shall be
         obligated to construct as part of the construction work hereunder such
         structures, fences, equipment, devices and other facilities as may be
         necessary or appropriate to accomplish the foregoing and all of the
         foregoing shall be covered under the plans and specifications of the
         User submitted under Section 3 hereof and shall be part of the
         construction work hereunder.

3.6.15.1 Notwithstanding the provisions of subsection 3.6.15 above and in
         addition thereto, Pan American hereby reserves the right from time to
         time and at any time during the term of the Agreement to require the
         User, subsequent to the completion of the construction work to design
         and construct at its sole cost and expense such further reasonable
         structures, fences, equipment, devices and other facilities as may be
         necessary or appropriate to accomplish the objectives as set forth in
         the first sentence of said subsection.

3.6.15.2 All locations, the manner, type and method of construction and the size
         of any of the foregoing shall be determined by Pan American. The User
         shall submit for Pan American's approval its plans and specifications
         covering the required work and upon receiving such approval shall
         proceed diligently to construct the same. All other provisions of this
         Section with respect to the construction work shall apply and pertain
         with like effect to any work which the User is obligated to perform
         pursuant to this subsection 3.6.15 and upon completion of each portion
         of such work it shall be and become a part of the construction work.
         The obligations assumed by the User under this subsection 3.6.15 are a
         special inducement and consideration to Pan American in granting this
         Agreement to the User.

4.       Other Construction by the User

4.1      Except as otherwise expressly provided herein, the User shall not erect
         any structures, make any improvements or do any other construction work
         on the Space, or install any fixtures (other than trade fixtures,
         removable without material damage to the Space, any such damage to be
         immediately repaired by the User) without the prior written approval of
         Pan American and in the event any construction, improvement,
         alteration, modification, addition, repair or replacement is made
         without such approval, then upon reasonable notice so to do, the User
         will remove the same or at the option of Pan American, cause the same
         to be changed to the satisfaction of Pan American. In case of any
         failure on the part of the User to comply with such notice, Pan
         American may effect the removal or change and User shall pay the cost
         thereof to Pan American.

4.2      In no event shall the User erect or be authorized to erect any
         structure on Area B.

5.       Fees to Pan American

5.1      Commencing upon the effective date and continuing each month until the
         completion of the sixtieth (60th) month of the term hereof, the User
         shall pay to Pan American a monthly fee of Sixteen Thousand Nine
         Hundred Sixty-Three Dollars ($16,963.00), subject to adjustment as
         hereinafter provided.

5.1.1    If the effective date occurs on a day other than the first day of a
         month, the fee payable for such month shall be prorated on the basis
         that the number of days from the effective date to the end of such
         month bears to the actual number of days in such month.

5.2      Commencing upon the date the User's contractor enters upon the Space to
         begin construction of the facilities set forth in Section 3.1 hereof
         and ending upon the Completion Date, the monthly fee set forth in
         Section 5.1 above shall be abated at the rate of One Thousand Two
         Hundred Thirty-Three Dollars ($1,233.00) per month.

5.3      Upon the effective date a structure known as Building 29 exists upon
         the Space. User is hereby authorized to demolish said structure in
         connection with the construction of facilities set forth in Section 3.1
         hereof and upon the date of completion of such demolition and removal
         of all debris, the monthly fee set forth in Section 5.1 above shall be
         abated at the rate of Nine Hundred Dollars ($900.00) per month.

5.4      Upon the effective date a structure known as Building 26 exists upon

         date of completion of such demolition and removal of all debris the
         monthly fee set forth in Section 5.1 above shall be abated at the rate
         of Fifty Dollars ($50.00) per month.

<PAGE>

5.5      Upon the effective date a structure known as Hangar No. 3 exists upon
         the Space. Subject to prior approval by the Port Authority and Pan
         American of an alteration application for the demolition of Hangar No.
         3, User may demolish said Hangar upon written authorization from Pan
         American to so proceed, and upon the date of completion of such
         demolition removal of all debris and appropriate supplemental site work
         to permit the Hangar No. 3 site to be used as an aircraft ramp, the
         monthly fee shall be abated by Five Thousand Three Hundred Eighty-Seven
         Dollars and Fifty Cents ($5,387.50) per month. Nothing contained herein
         shall constitute an obligation upon the Port Authority or Pan American
         to authorize the demolition of Hangar No. 3.

5.6      The abatements referred to in 5.3, 5.4 and 5.5 above shall become
         effective upon the date Pan American renders to User acceptance in
         writing of the demolition work.

5.7      Notwithstanding any provision hereof, User understands and acknowledges
         that upon the effective date of this Agreement Mars Aircraft Radio
         Service Company of New Jersey ("Mars") occupies approximately 2,096
         square feet on the second floor of the west lean-to of Hangar No. 3
         ("the Mars Space") under a Use and Occupancy Agreement with Pan
         American dated March 3, 1978 ("the Mars Agreement") and that said Mars
         Space is not a part of the Space under this Agreement. Starting with
         the second anniversary of the effective date of this Agreement or upon
         earlier termination of the Mars Agreement, whichever occurs first, the
         monthly fee shall be Seventeen Thousand Two Hundred Fifteen Dollars
         ($17,215.00), subject to abatement as provided in 5.2, 5.3, 5.4 and 5.5
         above and subject to proration for a fractional month as set forth in
         5.1.1; and thenceforth the Mars Space shall become a part of the Space
         under this Agreement.

5.7.1    During the occupancy of the Mars Space by Mars, User agrees to supply
         to Mars heat and electricity and agrees to permit Mars, its employees
         and customers to use the existing stairway leading from the hangar
         floor to the Mars Space and to use the common corridors for purposes of
         access to the Mars Space and as a means of access to the public street
         adjacent to the Space and to provide for the use of toilet facilities
         and washroom in the west lean-to of Hangar No. 3.

5.7.2    Further, User hereby agrees to the use by Mars, solely for its
         employees and customers, of twelve automobile parking spaces at rates
         mutually satisfactory to User and Mars; and to use space on aircraft
         parking ramps for the sole purpose of parking aircraft of Mars'
         customers at User established rates, provided, however, that such use
         by Mars shall be subject to approval by User as to location and that
         the exercise of such right of use shall not unreasonably interfere with
         User's operations on the Space.

5.7.3    User hereby agrees to the use by Mars of the Space for the erection of
         Mars' signs, subject to the approval of User and of Pan American of an
         alteration application.

5.8      Starting with the first day of the sixty-first (61st) full month of the
         term of this Agreement counting from the effective date and continuing
         for the next succeeding sixty (60) months, the monthly fee shall be
         Seventeen Thousand Two Hundred Fifteen Dollars ($17,215.00) (less any
         abatement granted to User under the provisions of Sections 5.3, 5.4 or
         5.5 above), multiplied by a fraction, the numerator of which shall be
         the Consumer Price Index for all urban consumers of the Bureau of Labor
         Statistics of the United States Department of Labor, all items,
         Selected Large Cities, for the New York-Northeastern New Jersey Area
         Base Year 1967 = 100 (hereinafter referred to as "the CPI") as
         published for the month in which the fee payment for the sixtieth
         (60th) full month of the term shall become due and the denominator of
         which shall be the CPI published for the month preceding the month in
         which the effective date falls.

5.8.1    Starting with the 121st monthly payment and continuing for the next
         succeeding sixty (60) months, the monthly payments shall be computed in
         the same manner as in Section 5.8 above, except that the numerator of
         the fraction shall be the CPI published for the month that the 120th
         monthly payment shall be due.

5.8.2    Starting with the 181st monthly payment and continuing for the next
         succeeding sixty (60) months, the monthly payments shall be computed in
         the same manner as 5.8 above except that the numerator of the fraction
         shall be the CPI published for the month that the 180th monthly payment
         shall be due.

5.8.3    Starting with the 241st monthly payment and continuing throughout the
         remaining term of the Agreement, the monthly payments shall be computed
         in the same manner as in 5.8 above except that the numerator of the
         fraction shall be the CPI published for the month that the 240th
         monthly payment shall be due.

5.8.4    In computing the adjustments for the monthly fees, in no event shall
         the monthly fees be less than the monthly fees payable during the five
         year period immediately preceding.

5.8.5    In the event any CPI is published using a base year other than 1967,

         place of receipt of the order therefor, and for sales made and for
         services rendered outside the Airport, if the order therefor is
         received at the Airport, and shall include revenues of any type arising

         January 1 of the calendar year following the effective date and each
         successive twelve month period thereafter.

5.9.5    In the event that Pan American shall enter into agreements with other
         users at the Airport providing for a percentage or other fee payable to
         Pan American for the sale of aircraft from the Airport, which fee is
         less than the fee as set forth in subsection 5.9.2 hereof, such lesser
         fee shall be substituted for the aforementioned fee upon the effective
         date of such agreement for such lesser fee with other users.

5.9.6    All gross receipts from the sale of aircraft by the User shall be
         considered as having been derived at the Airport and are subject to the

         the customer for the aircraft taken in trade shall be subject to the
         percentage fee, provided, however, that the aircraft taken in trade
         shall be subject to said fee at its resale price when sold.

5.9.8    Sales of aircraft owned by others for which User has acted as broker
         shall not be considered as gross receipts from sale of aircraft,
         provided, however, that the brokerage fee earned by User from such sale

         written notice to Pan American whenever any of User's rights and
         privileges hereunder are being exercised by any such firms,
         subsidiaries, corporations or entities. The foregoing shall not be
         deemed to grant to any such subsidiary, firm, corporation or entity any
         rights or privileges granted to User hereunder.

6.       Time of Payment and Computation of Amounts

6.1      User shall pay to Pan American the monthly fees specified in the
         Section entitled "Fees to Pan American" hereof in advance on the first
         (1st) day of each and every month until the termination of this
         Agreement, provided, however, if this Agreement is terminated other
         than the last day of the month the last payment shall be the then
         effective basic monthly fee prorated in the same proportion the number
         of days the Agreement was effective in the last month bears to thirty
         (30) days.

6.2      For each annual period the User shall pay the gross receipts percentage
         fee as follows: on the twentieth (20th) day of the first (1st) month
         following the effective date hereof and on the twentieth (20th) day of
         each and every month thereafter including the month following the end
         of the annual period, the User shall render to Pan American a statement
         certified by User's principal financial officer showing its gross
         receipts for the preceding calendar month and its cumulative gross
         receipts from the date of commencement of the annual period for which
         the report is made, through the last day of the preceding calendar
         month; whenever any such statement shall show that the cumulative gross
         receipts for the annual period are in excess of the annual exemption
         amount, the User shall pay to Pan American at the time of rendering the
         statement an amount equal to Five Percent (5%) of such excess and shall
         on the twentieth (20th) day of each month thereafter during the annual
         period and the month next succeeding that annual period, pay to Pan
         American an amount equal to Five Percent (5%) of the

                                       14
<PAGE>

         gross receipts of each subsequent month during the annual period. At
         any time that the annual exemption amount is decreased by abatement so
         that there is an excess of gross receipts as to which such percentage
         fee has not been paid the same shall be payable to Pan American on
         demand.

6.3      Upon any termination of the use and occupancy hereunder (even if stated
         to have the same effect as expiration, but in no event if termination
         of said use and occupancy is due to termination of the Basic Agreement
         either by the Port Authority pursuant to any of the provisions of
         Section 15 (a) thereof or by Pan American for any reason whatsoever),
         the User shall, within twenty (20) days of the effective date of such
         termination, make a payment of such percentage fees computed as
         follows: First, the User shall within twenty (20) days after the
         effective date of termination render to Pan American a statement of
         gross receipts certified by User's principal financial officer for the
         annual period in which the effective date of termination falls; and,
         second, the payment when due on account of all such percentage fees for
         the annual period in which the effective date of termination falls
         shall be the excess of such percentage fees computed as follows, over
         the total of such percentage fee payments previously made for such
         annual period: Five Percent (5%) of the gross receipts of the User for
         such annual period which are in excess of the annual exemption amount,
         said annual exemption amount being multiplied by a fraction, the
         numerator of which shall be the number of days from the commencement of
         the annual period to the effective date of termination, and the
         denominator of which shall be three hundred sixty-five (365).

6.4      Nothing contained in the foregoing shall affect the survival of the
         obligations of the User as set forth in the Sections of this Agreement
         covering the survival of the User's obligations.

6.5      User shall pay the percentage fee on gross receipts from sales of
         aircraft as follows: on the twentieth (20th) day of the first (1st)
         month following the commencement of the annual period and on the
         twentieth (20th) day of each and every month thereafter User shall
         render to Pan American a statement certified by User's principal
         financial officer showing its gross receipts from the retail sales of
         aircraft made during the preceding month and shall pay the percentages
         fee thereon at the time such statement is rendered. If no sales were
         made during any month, a negative statement shall be rendered to that
         effect.

6.6      The fees specified herein shall be payable at the office of the Manager
         of Teterboro Airport, 399 Industrial Avenue, Teterboro, New Jersey
         07608, or such other location as may from time to time be substituted
         therefor.

         orderly condition and appearance the Space and all the User's fixtures,

         fire-alarm, sewerage, drainage, water-supply and electrical systems,
         including all pipes, wires, lines, conduits, equipment and fixtures and
         shall make all necessary repairs and replacements and do all necessary
         rebuilding and repainting, regardless of the cause or the condition
         requiring the same.

7.4      In the event the User fails to commence so to repair, replace, rebuild
         or paint within a period of ten (10) days after notice from Pan
         American so to do, or fails diligently to continue to complete the
         repair, replacement, rebuilding or painting of all the Space required
         to be repaired, replaced, rebuilt or painted by the User under the
         terms of this Agreement, Pan American may, at its option, and in
         addition to any other remedies which may be available to it, repair,

         electricity necessary for the operation of the said lights, and shall
         operate the same in accordance with the directions of Pan American. Pan
         American hereby directs that all said obstruction lights shall until
         further notice, be operated daily for a period commencing thirty (30)

9.1      The User shall, during the term of this Agreement, insure and keep
         insured to the extent of One Hundred Percent (100%) of the replacement
         value thereof, all buildings, structures, improvements, installations,
         facilities, and fixtures now or in the future located on the Space
         against such hazards and risks as may now or in the future be included
         under the standard form of fire insurance policy of the State of New
         Jersey and also against damage or loss by windstorm, cyclone, tornado,
         hail, explosion, riot, civil commotion, aircraft, vehicles and smoke,
         under the standard form of fire insurance policy of New Jersey, and the
         form of extended coverage endorsement prescribed as of the effective
         date of the said insurance by the rating organization having
         jurisdiction, and also covering boiler and machinery hazards and risks
         and also, subject to the availability thereof, covering nuclear
         property losses and contamination hazards and risks in a separate
         insurance policy or policies or as an additional coverage endorsement
         to the aforesaid policies in the form as may now or in the future be
         prescribed as of the effective date of said insurance by the rating
         organization having jurisdiction.

9.2      The aforesaid insurance coverages and renewals thereof shall insure the
         Port Authority and Pan American as their interests may appear and shall
         provide that the loss, if any, shall be adjusted with Pan American and
         the Port Authority and shall be payable to the Port Authority or Pan
         American as their interests may appear.

9.3      In the event the Space or any part thereof shall be damaged by any
         casualty against which insurance is carried pursuant to this Section
         the User shall promptly notify Pan American of such casualty and shall
         thereafter furnish to Pan American such information and data as shall
         enable the parties to adjust the loss.

9.4      At least seven (7) days prior to the beginning of the term of this
         Agreement, the policies or certificates representing said insurance
         shall be delivered by the User to Pan American and each policy or
         certificate delivered shall bear an endorsement obligating the
         insurance company to furnish the Port Authority and Pan American twenty
         (20) days' advance notice of the cancellation of the insurance
         evidenced by said policy or certificates or of any changes or
         endorsements which may be made thereon. Renewal policies or
         certificates shall be delivered to Pan American at least twenty (20)
         days before the expiration of the insurance which such policies are to
         renew.

9.4.1    The aforesaid insurance shall be written by a company or companies
         approved by Pan American.

9.5      To the extent that any loss is recouped by actual payment to the Port
         Authority or Pan American of the proceeds of the insurance herein
         referred to above, such proceeds will be paid to the User to cover its
         costs of rebuilding or repairing the portion or all of the Space which
         has been damaged or destroyed. Such payment will be made by Pan
         American to the User in installments if requested by the User

                                       17
<PAGE>

         and as work progresses provided that as to each request for payment the
         User shall certify by a responsible officer or authorized
         representative thereof that the amounts requested are due and payable
         to its contractor for work completed. Upon completion of all the work,
         the User shall certify by a responsible officer or authorized
         representative that such rebuilding and repairs have been completed,
         that all costs in connection therewith have been paid by the User and
         said costs are fair and reasonable and said certification shall also
         include an itemization of costs. Nothing herein contained shall be
         deemed to release the User from any of its repair, maintenance or
         rebuilding obligations under the Agreement. If the proceeds of any such
         insurance paid to Pan American exceed the User's costs of rebuilding or
         repair, the excess of such proceeds shall be retained by Pan American.

9.6      If there is damage or destruction to the Space covered by insurance
         under this Section, the User shall promptly repair, rebuild or replace
         the damaged or destroyed portion of the Space.

9.7      If the User does not so properly proceed then Pan American may repair
         or rebuild and may apply such proceeds of such insurance towards such
         repair, replacement and rebuilding, but no such application shall
         relieve the User of its obligations under this Agreement.

9.8      If, moreover, there is damage or destruction to the property covered
         under this Section which occurs within the last three years of the term
         of the Agreement, the obligations of the User to repair, replace or
         rebuild such damaged or destroyed property at User's option may be
         discharged (provided that the insurance applicable thereto has been
         maintained in full force and effect) in which case the entire proceeds
         of the insurance applicable thereto shall be retained by Pan American.

9.9      The provisions of Section 9.1 above notwithstanding, the User may
         request, in writing, that Pan American secure and maintain the
         insurance coverage to the extent specified in said Section 9.1,
         provided, however, that the User shall reimburse Pan American for the
         cost thereof and provided, further, that the policy or policies
         provided by Pan American shall name the Port Authority and Pan American
         as insured under such policies and that any loss shall be adjusted with
         Pan American and the Port Authority as their interests may appear but
         that in the event the User is required to make repairs, replacement or
         rebuilding on the Space or any part thereof which is covered by the
         aforesaid insurance, the proceeds thereof shall be made available to
         the User for the purpose of performing its obligations in the same
         manner and same extent as set forth in Section 9.5 hereof.

9.9.1    In the event User elects to request Pan American to provide the
         insurance as set forth in 9.9 above, and said insurance is in fact
         provided, Pan American agrees and hereby grants the User and any
         sub-user of the Space approved in writing by Pan American, a waiver of
         subrogation under said fire insurance policy or policies, provided,
         however, that if Pan American deems the operations

                                       18
<PAGE>

         performed on or within the Space by the User or such approved sub-user
         are extra hazardous or otherwise will invalidate the terms of said fire
         insurance policy or policies, the said waiver of subrogation shall be
         withdrawn by Pan American.

10.      Indemnity, Liability Insurance

10.1     The User shall indemnify and hold harmless the Port Authority, its
         Commissioners, officers, employees and representatives; and Pan
         American, its Directors, officers, employees and representatives from
         all claims and demands of third persons, including, but not limited to,
         claims and demands for death or personal injury or for property damages
         arising out of the use and occupancy of the Space by the User or out of
         any other acts or omissions of the User, its officers, employees on the
         Space or out of the acts or omissions of others on the Space with
         consent of the User, excepting only claims and demands which result
         solely from negligent acts done by Pan American, its Directors,
         officers, agents and employees.

10.2     In addition to the obligations set forth in the above subsection, the
         User, in its own name as assured, shall maintain and pay the premiums
         on the following described policies of comprehensive public liability
         insurance and automobile liability insurance which shall cover its
         operations hereunder and shall be effective throughout the term in
         limits not lower than the following:

                  Non-Owned Vehicles
                  Hired Vehicles

10.3     Neither the Port Authority nor Pan American shall be named as an
         insured in any policy of insurance required by this Section, unless the
         Port Authority or Pan American shall, at any time during the effective
         period of this Agreement, direct otherwise in writing, in which case
         the User shall cause the Port Authority and/or Pan American to be so
         named. As to any insurance required by the provisions of this Agreement
         to secured by or at the direction of the User, a certified copy of each
         of the policies or certificates evidencing the existence thereof, or
         binders,

                                       19
<PAGE>

         together with evidence of the payment of the premium thereon, shall be
         delivered to Pan American within fifteen (15) days prior to occupancy
         by User of the Space. In the event any binder is delivered, it shall be
         replaced within thirty (30) days by a certified copy of the policy or a
         certificate. Each such copy or certificate shall contain a valid
         provision or endorsement that the policy may not be cancelled,
         terminated, changed or modified without giving twenty (20) days'
         written advance notice thereof to Pan American. A renewal policy shall
         be delivered to Pan American at least twenty (20) days prior to the
         expiration date of each expiring policy, except for any policy expiring
         after the date of expiration of the term. If at any time any of the
         policies shall be or become unsatisfactory to Pan American as to form
         or substance or if any of the carriers issuing such policies shall be
         or become unsatisfactory to Pan American, the User shall promptly
         obtain a new and satisfactory policy in replacement.

11.1     The User, its customers, its contractors, suppliers of material and
         furnishers of services shall have the right of ingress and egress
         between the Space and the city streets or public ways outside the
         Airport by means of such pedestrian or vehicular roadways to be used in
         common with others having rights of passage within the Airport, as may
         from time to time be designated by Pan American for the use of the
         public.

11.2     The User shall have the right of ingress and egress between the Space
         and the public landing areas at the Airport by means of connecting
         taxiways, to be used in common with others having rights of passage
         thereon.

11.3     The use of any such roadway or taxiway shall be subject to the Rules
         and Regulations of the Airport which are now in effect or which may
         hereafter be promulgated for the safe and efficient operation of the
         Airport. Pan American may, at any time, temporarily or permanently,
         close or consent to or request the closing of, any such roadway or
         taxiway and any other way at, in or near the Space presently or
         hereafter used as such, so long as a reasonable means of ingress and
         egress as provided above remains available to the User. Subject to the
         foregoing obligation the User hereby releases and discharges the Port
         Authority, its Commissioners, officers, employees and agents; Pan
         American, its Directors, officers, employees and agents and all
         municipalities and other governmental authorities and their respective
         successors and assigns, of and from any and all claims, demands or
         causes of action which the User may now or at any time hereafter have
         against any of the foregoing, arising or alleged to arise out of the
         closing of any street, roadway or other area, whether within or outside
         the Space. The User shall not do or permit anything to be done which
         will interfere with the free access and passage of others to space
         adjacent to the Space or in any streets or roadways near the Space.

12.      Various Obligations of the User

12.1     The User shall conduct its operations in an orderly and proper manner
         and so as not to annoy, disturb or be offensive to others at the Space.
         The User shall take all reasonable measures:

12.1.1   to eliminate vibrations tending to damage any equipment, structure,
         building or portion of a building which is on the Space, or is a part
         thereof, or is located elsewhere on the Airport, and

12.1.2   to keep the sound level of its operations as low as possible.

12.2     The User shall control the conduct, demeanor and appearance of its
         employees and invitees and of those doing business with it, and upon
         objection from Pan American concerning the conduct, demeanor or
         appearance of any such shall immediately take all lawful steps
         necessary to remove the cause of the objection. If Pan American shall
         so request, the User agrees to supply and require its employees to wear
         or carry badges or other suitable means of identification, which shall
         be subject to the prior and continuing approval of the Manager of the
         Airport.

12.3     It is the intent of the parties hereto that noise caused by aircraft
         engine operation shall be held to a minimum. To this end the User will
         conduct its operations in such a manner as to keep the noise produced
         by aircraft engines and component parts thereof to a minimum by such
         methods as are practicable, considering the extent and type of the
         operations of the User. In addition, the User will employ the maximum
         amount of noise arresting and noise reducing devices that are available
         and economically practicable, considering the extent of the operations
         of the User. In its use of the Space, the User shall take all possible
         care, caution and precaution and shall use its best efforts to minimize
         prop or jet blast interference to aircraft operating on or to
         buildings, structures and roadways, now located on or which in the
         future may be located on areas adjacent to the Space. In the event Pan
         American determines that the User has not curbed the prop or jet blast
         interference, the User hereby covenants and agrees to erect and
         maintain at its own expense such structure or structures as may be
         necessary to prevent prop or jet blast interference subject, however,
         to the prior written approval of Pan American as to type, manner and
         method of construction.

12.4     The User shall daily remove from the Space by means of facilities
         provided by it all garbage, debris and other waste materials arising
         out of or in connection with its operations hereunder, and any such not
         immediately removed shall be temporarily stored in a clean and sanitary
         condition in suitable garbage and waste receptacles, the same to be
         made of metal and equipped with tight-fitting covers, and to be of a
         design safely and properly to contain whatever material may be placed
         therein, said receptacles being provided and maintained by the User.
         The receptacles shall be kept covered except when filling or emptying
         the same. The User shall exercise extreme care in removing such
         garbage, debris and other

                                       21
<PAGE>

         waste materials from the Space. The manner of such storage and removal
         shall be subject in all respects to _______________________. No
         facilities of the Airport shall be used for such removal unless with
         Pan American's prior consent in writing. No such garbage, debris or
         other waste materials shall be or be permitted to be thrown, discharged
         or disposed into or upon the waters at or bounding the Space.

12.5     It is intended that the standards and obligations imposed by this
         Section shall be maintained or complied with by the User in addition to
         its compliance with all applicable Federal, State and Municipal laws,
         ordinances and regulations, and in the event that any of said laws,
         ordinances and regulations shall be more stringent than such standards
         and obligations, the User agrees that it will comply with such laws,
         ordinances and regulations in its operations hereunder. Changes in such
         laws or regulations are not grounds for termination of this Agreement.

12.6     The User shall promptly observe, comply with and execute the provisions
         of any and all present and future rules and regulations, requirements,
         orders and directions of the National Fire Protection Association and
         the Fire Insurance Organization of New Jersey or of any other board or
         organization exercising or which may exercise similar functions which
         may pertain or apply to the operations of the User on the Space and the
         User shall, subject to and in accordance with the provisions of this
         Agreement relating to construction by the User, make any and all
         structural or nonstructural improvements, alterations or repairs of the
         Space that may be required at any time hereafter by any such present or
         future rule, regulation, requirement, order or direction. If by reason
         of any failure on the part of the User to comply with the provisions of
         this Section, any fire insurance, extended coverage or other insurance
         rate on the Space or any part thereof, or on the Airport or any part
         thereof, shall at any time be higher than it otherwise would be, then
         the User shall pay to Pan American that part of all premiums paid by
         Pan American which shall have been charged because of such violation or
         failure by the User.

12.7     In connection with the conduct of User's business the User shall:

12.7.1   use its best efforts in every proper manner to maintain, develop and
         increase the business conducted by it hereunder;

12.7.2   not divert, cause or allow to be diverted, any business from the
         Airport;

12.7.3   maintain in accordance with accepted accounting practice during the
         term hereof User's records and books of account recording all
         transactions at, through or in anywise connected with the Airport which
         records and books of account shall be kept at all times at the User's
         place of business at the Airport;

12.7.4   permit in ordinary business hours during the term hereof and for one
         (1) year thereafter the examination and audit by the officers,
         employees or representatives of Pan American of such records and books
         of account and also any records and

                                       22
<PAGE>

         books of account of any company owned or controlled by the User if said
         Company performs services similar to those performed by the User
         anywhere at the Airport.

12.7.5   The User shall be solely responsible for compliance with the provisions
         of this Section and no act or omission of Pan American shall relieve
         the User _______________________.

12.8     In addition to compliance by the User with all laws, ordinances,
         governmental rules, regulations and orders now or at any time in effect
         during the term of the use hereunder which as a matter of law are
         applicable to the operation, use or maintenance by the User of the
         Space or the operations of the User under this Agreement (the foregoing
         not to be construed as a submission by Pan American or the Port
         Authority to the application to itself of such requirements or any of
         them), the User agrees that it shall conduct all its operations under
         the Agreement and shall operate, use and maintain the Space in
         accordance with a high standard and in such manner that there will be
         at all times a minimum of air pollution, water pollution or any other
         type of pollution and a minimum of noise emanating from, arising out of
         or resulting from the operation, use or maintenance of the Space by the
         User and from the operations of the User under this Agreement. Pan
         American hereby reserves the right from time to time and at any time
         during the term of the Agreement to require the User, and the User
         agrees to design and construct at its sole cost and expense such
         reasonable structures, fences, equipment, devices and other facilities
         as may be necessary or appropriate to accomplish the objectives as set
         forth in the first sentence of this paragraph. All locations, the
         manner, type and method of construction and the size of any of the
         foregoing shall be determined by Pan American. The User shall submit
         for Pan American approval a Construction Application together with its
         plans and specifications covering the required work and upon receiving
         such approval shall proceed diligently to construct the same.

12.9     The obligations assumed by the User under the above paragraph shall
         continue throughout the term of this Agreement and shall not be
         limited, affected, impaired or in any manner modified by the fact that
         Pan American or the Port Authority shall have approved any Construction
         Application and supporting plans, specifications and contracts covering
         construction work and notwithstanding the incorporation therein of Pan
         American's or the Port Authority's recommendations or requirements and
         notwithstanding that Pan American and the Port Authority may have at
         any time during the term of the Agreement consented to or approved any
         particular procedure or method of operation which the User may have
         proposed, or Pan American or the Port Authority may have itself
         prescribed the use of any procedure or method. The agreement of the
         User to assume the obligations under the above paragraph is a special
         inducement and consideration to Pan American in entering into this
         Agreement with the User.

         install, maintain, operate or permit the installation, maintenance or
         operation of any restaurant, kitchen, stand or other establishment of
         any type for the sale of food or of any vending machines or device
         designed to dispense or sell merchandise or services of any kind to the
         public, except that User may, for the benefit of its employees,
         customers, guests and visitors install coin operated vending machines
         or services for the dispensing and sale of the following:

13.1.1   Hot and cold packaged foods

13.1.4   Tobacco and tobacco products

13.1.5   Newspapers and periodicals

13.1.6   Telephone services (pay stations)
         (hereinafter called "vending machines").

13.2     If User, by itself or by contractors installs vending machines on the
         Space for the limited sale of merchandise or services permitted
         hereunder, it shall have the right to retain the revenues derived
         therefrom, provided, however, that

13.3     The User shall itself and shall also require its contractors to
         indemnify and hold harmless Pan American, its Directors, officers,
         agents and employees and the Port Authority, its Commissioners,
         officers, agents and employees from and against all claims and demands
         of third persons (including employees, officers and agents of Pan
         American and the Port Authority) arising or alleged to arise out of the
         installation, operation or maintenance of the vending machines or
         arising or alleged to arise out of any actual or alleged infringement
         of any patent, trademark or copyright or any alleged or actual unfair
         competition in any wise connected with the operation of the vending
         machines.

13.4     The limited right to install, operate and maintain vending machines
         granted to User herein may be terminated by Pan American at any time
         during the term of this Agreement upon ninety (90) days' notice to the
         User and Pan American, at any time thereafter, may substitute for the
         User's vending machines other machines selling similar merchandise or
         services operated by Pan American or by its permittee or
         concessionnaire and thereupon User shall remove its machines.

13.5     Upon installation by Pan American or by its permittee or
         concessionnaire of vending machines in substitution of User's vending
         machines, all revenues derived therefrom shall be retained by Pan
         American.

                                       24
<PAGE>

13.6     Upon rendering of notice to User of termination of the right to operate
         vending machines, Pan American may elect to permit User's vending
         machines to remain, but in such case, User shall pay or cause to be
         paid to Pan American each month for each machine upon the same basis
         for the preceding month as any permittee or concessionnaire of Pan
         American then operating machines at the Airport for sale to the general
         public of similar merchandise or rendering of similar services.

13.7     The termination by Pan American of the limited right of User to install
         vending machines at the Space shall be non-discriminatory in that
         similar rights granted to other Users at the Airport shall be
         terminated concurrently therewith, and in the exercise of such right by
         Pan American User shall not be entitled to assert any claim or
         institute any action or proceeding at law or in equity to assert any
         claim on account thereof whether for loss, damages or loss of revenue,
         consequential or otherwise.

13.8     The User shall not overload any floor or paved area on the Space and
         shall repair any floor including supporting members and any paved area
         damaged by overloading.

13.9     The User shall not do or permit to be done anything which may interfere
         with the effectiveness or accessibility of the utility, mechanical,
         electrical, drainage and sewer systems, fire-protection system and
         other systems installed or located on or in the Space.

13.10    The User shall not commit any nuisance or permit its employees or
         others on the Space with its consent to commit or create or continue or
         tend to create any nuisance on the Space or in or near the Airport.

13.11    The User shall not cause or permit to be caused or produced upon the
         Space, to permeate the same or to emanate therefrom, any unusual,
         noxious or objectionable smokes, gases, vapor or odors.

13.12    The User shall not do or permit to be done any act or thing upon the
         Space which:

13.12.1  will invalidate or conflict with any fire insurance policies covering
         the Space or any part thereof, or the Airport, or any part thereof; or

13.12.2  which, in the opinion of Pan American, may constitute an
         extra-hazardous condition so as to increase the risks normally
         attendant upon the operations permitted by this Agreement; or

13.12.3  which will increase the rate of any fire insurance, extended coverage
         or other insurance on the Airport or any part thereof or upon the
         contents of any building thereon.

13.13    Except persons who have been granted valid permits from Pan American,
         User shall not permit, foster or allow on the Space any persons who

<PAGE>

13.13.1  doing maintenance work on aircraft not owned solely by said persons,

13.13.2  giving flight instruction of any sort unless such persons are members
         of User's flight instruction staff, or

14.      Rules and Regulations

14.1     User shall observe and obey and shall compel others on the Space and
         those doing business with it with respect to the Space to observe and
         obey such Rules and Regulations of the Airport as are now in effect or
         as may be promulgated from time to time for the government and conduct
         of operations for reasons of safety, health or preservation of
         property, for the good and orderly appearance of the Space and for the
         safe and efficient operation and use of the Space. If a copy of the
         Rules and Regulations is not attached, then Pan American will make a
         copy thereof available to the User at the office of the Manager of
         Teterboro Airport.

15.      Signs

15.1     Except with the prior written approval of Pan American, the User shall
         not erect, maintain or display any advertising, signs, posters or
         similar devices at or on the Space.

15.2     Upon demand by Pan American, the User shall remove, obliterate or paint
         out any and all advertising, signs, posters and similar devices placed
         by the User on the Space or elsewhere on the Airport without the prior
         approval of Pan American. In the event of a failure on the part of the
         User so to remove, obliterate or paint out each and every sign or piece
         of advertising and so to restore the Space and the Airport, Pan
         American may perform the necessary work and the User shall pay the
         costs thereof to Pan American on demand.

16.      Assignment

16.1     The User agrees that it will not grant the right of sub-use, sell,
         convey, transfer, assign, mortgage or pledge this Agreement or any part
         thereof or any rights granted thereby without the prior written consent
         of Pan American.

16.2     If the User assigns, sells, conveys, transfers, mortgages, pledges or
         grants the right of sub-use under this Agreement in violation of the
         foregoing provisions of this Section, or if the Space is occupied by
         anyone other than the User, Pan American may collect from any assignee,
         sub-user or anyone who claims a right to this Agreement or who occupies
         the Space any charges or fees payable by it and shall apply the net
         amount collected to the fees, herein reserved; and no such collection
         shall be deemed a waiver by Pan American of the agreements contained in
         this Section nor of acceptance by Pan American of any assignee,
         claimant or occupant, nor as a release of the User by Pan American from
         the further performance by the User of the agreements contained herein.

                                       26

17.      Condemnation

17.1     The User, in any action or proceeding instituted by any governmental
         agency or agencies for the taking for a public use of any interest in
         all or any part of the Space, shall not be entitled to assert any claim
         to any compensation or award or part thereof made or to be made therein
         or therefor, or to institute any action or proceeding or to assert any
         claim against such agency or agencies or against the Port Authority or
         Pan American for or on account of any such taking (except the possible
         claim to an award for loss of the User's removable fixtures), it being
         understood and agreed between Pan American and the User that Pan
         American shall be entitled to all the compensation or awards made or to
         be made or paid for in such taking, free of any claim or right of the
         User.

17.2     In the event of a taking of the entire Space by any governmental agency
         or agencies, then this Agreement shall be cancelled as of the date
         possession is taken from the Port Authority by the agency or agencies,
         and shall cease and determine in the same manner and with the same
         effect as if the Agreement had on that date expired.

17.3     In the event of a taking by any governmental agency or agencies of a
         part of the Space, then use as to such part only shall, as of the date
         possession thereof is taken from the Port Authority by such agency or
         agencies, cease and determine, and the Fees thereafter to be paid by
         the User to Pan American shall be abated as hereinafter provided from
         and after the date of such taking. In the event that a substantial part
         shall be taken which shall be deemed to mean a taking so extensive that
         the User is unable to use or operate the Space for the purposes
         expressed in this Agreement, then the User shall have the right to be
         exercised within thirty (30) days of the taking to terminate this
         Agreement, such termination to have the same effect as expiration.

17.4     In the event that all or any portion of the Space is required by the
         Port Authority to comply with any present or future governmental law,
         rule, regulation, requirement, order or direction, Pan American may by
         notice given to the User terminate the Agreement with respect to all or
         such portion of the Space so required. Such termination shall be
         effective on the date specified in the notice. The User hereby agrees
         to deliver possession of all or such portion of Space so required upon
         the effective date of such termination. No taking by or conveyance to
         any governmental authority as described in this Section, nor any
         delivery by the User nor taking by the Port Authority pursuant to this
         subsection shall be or be construed to be a breach of this Agreement or
         be made the basis of any claim by the User against the Port Authority
         or Pan American for damages, consequential or otherwise.

17.5     In the event a taking or conveyance as set forth above occurs with
         respect to all or any portion of the new building or new structures
         which shall be erected or constructed by the User, Pan American shall
         pay to the User the unamortized capital investment (as is hereinafter
         defined), if there be any, of such new building

                                       27
<PAGE>

         or new structures, provided, however, that with respect to a taking or
         conveyance the sums payable to the User by Pan American shall be
         limited to the extent of amounts covering the foregoing which shall
         have actually been paid to Pan American by the Port Authority or by
         others under the terms of the Basic Agreement, which amounts shall have
         been paid to Pan American through the Port Authority by the
         governmental agency or agencies, it being understood that the User
         shall not have any claim whatsoever against Pan American or the Port
         Authority by reason of insufficient or claimed insufficiency of the
         amounts so paid to Pan American. Payment to the User shall be made
         within sixty (60) days after receipt of the notice by Pan American from
         the Port Authority that payments have been received by the Port
         Authority from the governmental agency or agencies and confirmation
         that the Port Authority will reimburse Pan American upon evidence of
         payment to User.

17.6     The unamortized capital investment referred to in the above subsection
         shall be the capital investment in all or any part of the new building
         or new structures which shall be erected at the Space by the User with
         the approval of Pan American as referred to in the Section entitled
         "Construction by User" of this Agreement (as may be affected by the
         taking or conveyance in whole or in part), multiplied by a fraction,
         the numerator of which shall be the number of whole calendar months
         between the effective date of taking or termination as set forth above,
         and the end of the amortization period of each such new building or new
         structures as hereinafter set forth, and the denominator of which shall
         be the total said amortization period of such new building or new
         structures.

17.7     Except as otherwise agreed to by the parties hereto prior to
         commencement of construction, the amortization period with respect to
         each such new structure or new building shall commence as of the date
         of substantial completion of the same, shall be computed in whole
         months, and shall be:

17.7.1   the useful life of the new building or new structure as determined
         under sound accounting practice; or

17.7.2   two hundred forty (240) months; or

17.7.3   to termination of the term hereof, whichever is least of the above.

17.8     For purposes of this Agreement and to the extent permitted by sound
         accounting practice, the capital investment of the User for each such
         new building or new structure shall mean the sum of the following
         items:

17.8.1   payments to independent contractors and suppliers of materials,
         excluding any payments for engineering, architectural planning or
         designing services, engaged or retained by the User for the actual
         construction of the work, including site preparation and bringing
         utilities to the site; and

17.8.2   an amount equal to Ten Percent (10%) of the above item.

                                       28
<PAGE>

17.9     A statement of capital investment in duplicate detailing all of the
         foregoing including two copies of invoices and contracts and certified
         by the principal financial officer of the User shall be delivered to
         Pan American not later than forty-five (45) days after completion of
         any construction, and the User shall permit Pan American and the Port
         Authority by their agents, employees or representatives at all
         reasonable times prior to a final settlement or determination of
         capital investment to examine and audit the records and books of the
         User which pertain to the capital investment and the User agrees to
         keep such records and books of account within the District of the Port
         Authority during such time. If in the certified statement, there is
         included any item of cost or expense as having been incurred which in
         the opinion of Pan American or the Port Authority was not so incurred,
         or which in the opinion of Pan American or the Port Authority was not a
         cost or expense properly chargeable to the capital investment under
         sound accounting practice, within one hundred eighty (180) days after
         completion of audit and examination by the Port Authority and Pan
         American, Pan American shall give written notice to the User stating
         its objection to such item and the grounds therefor, which notice shall
         be considered final in the determination of the capital investment.

17.10    There shall be excluded from the capital investment any cost of
         personal property.

17.11    Notwithstanding any other provision of this Agreement, in ascertaining
         the amount Pan American shall be obligated to pay the User under the
         terms of this Section the unamortized capital investment of each such
         new structure or new building shall be diminished by the amount that
         any part of the components of any costs thereof are secured by liens,
         mortgages or other encumbrances or conditional bills of sale on said
         capital investment and less any other amounts whatsoever due to Pan
         American by the User under this Agreement or any other agreement with
         the User at the Airport. The capital investment for any such new
         structure or new building shall not include any expenses, outlays or
         charges by or for the account of the User for or in connection with the
         work unless said work is actually made and completed and becomes part
         of the Space.

18.      Non-Discrimination

18.1     Without limiting the generality of any of the provisions of this
         Agreement, the User, for itself, its successors in interest, and
         assigns, as a part of the consideration hereof, does hereby covenant
         and agree as a covenant running with the land that (1) no person on the
         grounds of race, color, or national origin shall be excluded from
         participation in, denied the benefits of, or be otherwise subjected to
         discrimination in the use of the Space, (2) that in the construction of
         any improvement on, over, or under the Space and the furnishing of
         services thereon, no person on the grounds of race, color, or national
         origin shall be excluded from participation in, denied the benefits of,
         or otherwise subjected to discrimination, (3) that the User shall use
         the Space in compliance with all other requirements imposed by or
         pursuant to Title 49, Code of Federal Regulations, Department of
         Transportation, Subtitle A, Office of the Secretary, Part 21,

                                       29

         Nondiscrimination in Federally-assisted programs of the Department of
         Transportation-Effectuation of Title VI of the Civil Rights Act of
         1964, and as said Regulations may be amended, and any other present or
         future laws, rules, regulations, orders or directions of the United
         States of America with respect thereto which from time to time may be
         applicable to the User's operations thereat, whether by reason of
         agreement between Pan American and the United States Government or
         otherwise.

18.2     The User shall include the provisions of the above subsection in every
         agreement or concession pursuant to which any person or persons, other
         than the User, operates any facility at the Space providing services to
         the public and shall also include therein a provision granting Pan
         American a right to take such action as the United States may direct to
         enforce such covenant.

18.3     The User's noncompliance with the provisions of this Section shall
         constitute a material breach of the Agreement. In the event of the
         breach by the User of any of the above nondiscrimination provisions,
         Pan American may take any appropriate action to enforce compliance; or
         in the event such noncompliance shall continue for a period of twenty
         (20) days after receipt of written notice from Pan American, Pan
         American shall have the right to terminate this Agreement with the same
         force and effect as a termination under the Section of the Agreement
         providing for termination for default by the User in the performance or
         observance of any other term or provision of the Agreement; or may
         pursue such other remedies as may be provided by law; and as to any or
         all of the foregoing, Pan American may take such action as the United
         States may direct.

18.4     The User shall indemnify and hold harmless Pan American and the Port
         Authority from any claims and demands of third persons including the
         United States of America resulting from the User's noncompliance with
         any of the provisions of this Section and the User shall reimburse Pan
         American and the Port Authority for any loss or expense incurred by
         reason of such noncompliance.

18.5     Nothing contained in this Section shall grant or shall be deemed to
         grant to the User the right to transfer or assign the Agreement, to
         make any agreement or concession of the type mentioned in this Section,
         or any right to perform any construction on the Space.

19.      Governmental Requirements

19.1     The User shall procure all licenses, certificates, permits or other
         authorization from all governmental authorities, if any, having
         jurisdiction over the User's operations at the Space which may be
         necessary for the User's operations thereat.

19.2     The User shall pay all taxes, license, certification, permit and
         examination fees and excise which may be assessed, levied, exacted or
         imposed on the Space or operation hereunder or on the gross receipts or
         income to User therefrom, and shall make all applications, reports and
         returns required in connection therewith.

                                       30

19.3     Pan American has agreed by a provision in its agreement with the Port
         Authority covering the Airport to conform to the enactments,
         ordinances, resolutions and regulations of various governmental
         authorities having jurisdiction and of their various departments,
         boards and bureaus in regard to construction and maintenance of
         buildings and structures and in regard to health and fire protection.
         The User shall, within forty-eight (48) hours after its receipt of any
         notice of violation, warning notice, summons or other legal process for
         the enforcement of any such enactment, ordinance, resolution or
         regulation, deliver the same to Pan American. Unless otherwise directed
         in writing by Pan American because the same is inapplicable, the User
         shall conform to such enactments, ordinances, resolutions and
         regulations insofar as they relate to the operations of the User at the
         Space. In the event of compliance with any such enactment, ordinance,
         resolution or regulation on the part of the User, acting in good faith,
         commenced after such delivery to Pan American but prior to the receipt
         by the User of a written direction from Pan American, such compliance
         shall not constitute a breach of this Agreement, although Pan American
         thereafter notifies the User to refrain from such compliance.

19.4     The User shall promptly observe, comply with and execute the provisions
         of any and all present and future governmental laws, rules,
         regulations, requirements, orders and directions which may pertain or
         apply to the User's operations at the Space.

19.5     The User's obligations to comply with governmental requirements are
         provided herein for the purpose of assuring proper safeguards for the
         protection of persons and property at the Space.

20.      Rights of Entry Reserved

20.1     The Port Authority, by its officers, employees, agents, representatives
         and contractors and Pan American by its officers, employees, agents,
         representatives and contractors shall have the right at all reasonable
         times to enter upon the Space for the purpose of inspecting the same,
         for observing the performance by the User of its obligations under this
         Agreement and for the doing of any act or thing which the Port
         Authority or Pan American may be obligated or have the right to do
         under this Agreement, or otherwise.

20.2     Without limiting the generality of the foregoing, Pan American, by its
         officers, employees, agents, representatives and contractors and by the
         employees, agents, representatives and contractors of any furnisher of
         utility services in the vicinity, shall have the right, for its own
         benefit, for the benefit of the User, or for the benefit of others than
         the User at the Airport, to maintain existing and future utilities
         systems or portions thereof on the Space, including therein, without
         limitation thereto, systems for the supply of heat, water, gas, fuel,
         electricity and for the furnishing of fire-alarm, fire-protection,
         sprinkler, sewerage, drainage, telegraph and telephone services,
         including all lines, pipes, mains, wires, conduits and equipment
         connected with or appurtenant to such systems, and to enter upon

                                       31
<PAGE>

         the Space at all reasonable times to make such repairs, replacements or
         alterations as may, in the opinion of Pan American, be deemed necessary
         or advisable and, from time to time to construct or install over, in or
         under the Space new systems or parts thereof, including lines, pipes,
         mains, wires, conduits and equipment; provided, however, that in the
         exercise of such rights of repair, alteration or new construction Pan
         American shall not unreasonably interfere with the use and occupancy of
         the Space by the User.

20.3     The exercise of any or all of the foregoing rights by the Port
         Authority, Pan American or others shall not be or be construed to be an
         eviction of the User nor be made the grounds for any abatement of fees,
         nor any claim or demand for damages, consequential or otherwise.

20.4     Nothing in this Section shall impose or shall be construed to impose
         upon Pan American or the Port Authority any obligation so to construct
         or maintain or to make repairs, replacements, alterations or additions,
         or shall create any liability for any failure so to do.

21.      Basic Agreement

21.1     In the event the Basic Agreement is terminated, revoked, cancelled or
         expires, this Agreement shall terminate on the day preceding such date
         the same as if such preceding date were the expiration date of the term
         of this Agreement.

22.      Patents, Trademarks

22.1     The User represents that it is the owner of or fully authorized to use
         any, and all services, processes, machines, articles, marks, names or
         slogans used by it in its operations under or in anywise connected with
         this Agreement. The User agrees to save and hold the Port Authority,
         Pan American, their Commissioners, Directors, officers, employees,
         agents and representatives free and harmless of and from any loss,
         liability, expense, suit or claim for damages in connection with any
         actual or alleged infringement of any patent, trademark or copyright,
         or arising from any alleged or actual unfair competition or other
         similar claim arising out of the operations of the User under or in
         anywise connected with this Agreement.

23.      Additional Fees and Charges

23.1     If Pan American is required or elects to pay any sum or sums or incurs
         any obligations or expense by reason of the failure, neglect or refusal
         of the User to perform or fulfill any one or more of the conditions or
         agreements contained in this Agreement, or as a result of an act or
         omission of the User contrary to the said conditions and agreements,
         the User agrees to pay the sum or sums so paid or the expense so
         incurred, including all interest, costs, damages and penalties, and the
         same may be added to any installment of Fees thereafter due hereunder,
         and each and every part of the same shall be and become additional
         Fees, recoverable by Pan American in the same manner and with like
         remedies as if they were

                                       32
<PAGE>

         originally a part of the Fees as set forth in the Section entitled
         "Fees to Pan American" hereof.

24.      Right of Re-Entry

24.1     Pan American shall, as an additional remedy upon the giving of a notice
         of termination as provided in the Section entitled "Termination by Pan
         American" hereof, have the right to re-enter the Space and every part
         thereof upon the effective date of termination without further notice
         of any kind, and may regain and resume possession either with or
         without the institution of summary or any other legal proceedings or
         otherwise. Such re-entry or regaining or resumption of possession,
         however, shall not in any manner affect, alter or diminish any of the
         obligations of the User under this Agreement, and shall in no event
         constitute an acceptance of surrender.

25.      Surrender

25.1     The User covenants and agrees to yield and deliver peaceably to Pan
         American possession of the Space on the date of cessation of the
         Agreement, whether such cessation be by termination, expiration or
         otherwise, promptly and in good condition, except for reasonable wear
         which does not cause or tend to cause deterioration of the improvements
         or adversely affect the efficiency or proper utilization thereof.

26.      Termination by Pan American

26.1     Upon the occurrence of any of the following events or at any time

26.3     No acceptance by Pan American of fees, charges, or other payments in
         whole or in part for any period or periods after a default of any of
         the terms, agreements and conditions hereof to be performed, kept or
         observed by the User shall be deemed a waiver of any right on the part
         of Pan American to terminate this Agreement.

26.4     No waiver by Pan American of any default on the part of the User in
         performance of any of the terms, covenants or conditions hereof to be

         (60) days by action of any governmental agency having jurisdiction
         thereof, from conducting its operations at the Airport, regardless of
         the fault of the User," the sole right of Pan American shall be a right
         of termination.

27.      Services by User

27.1     A principal purpose of Pan American in the making of this Agreement is
         to make available at the Airport the items and/or services which the
         User is permitted to sell and/or render hereunder and the User hereby
         warrants and agrees that it will conduct a first-class operation and

         (including licensed personnel as necessary), supplies, materials, and
         facilities.

27.2.5   Pan American and User recognize the desirability and the existing need
         to provide aircraft maintenance services to User's hangar occupants;
         therefore, as a special, inducement for Pan American in entering into
         this Agreement User hereby agrees to continue providing or cause to be
         provided FAA approved personnel and facilities for maintenance
         servicing and repair of aircraft during the term of this Agreement, so
         long as the rendering of such services are economically justifiable. In
         the event the economics of rendering such services are such as to
         impose such severe financial hardship upon the User that can only be
         relieved by the discontinuance thereof by User, User shall render sixty
         (60) days' written notice to Pan American of its intention to so
         discontinue, together with financial data and other factors supporting
         such decision. Concurrently with notice to Pan American, User shall
         notify its customers in order that they may assess the continued need
         for such services. User shall take all appropriate steps consistent
         with this Agreement and consistent with User's existing space and its
         insurance requirements to assist and permit its customers in making
         alternate arrangements for the provision of maintenance services.

         It is clearly understood by Pan American and User that in the event
         User terminates maintenance services for economic reasons that User's
         customers may with User's permission which shall not unreasonably be
         withheld have FAA approved and qualified maintenance personnel perform
         maintenance on User's customers' aircraft within User's Space provided
         the User is properly indemnified.

         In the event User discontinues maintenance services (except temporary
         disruption due to labor disputes) for reasons other than financial
         hardship directly attributable to rendering such services, such
         discontinuance shall constitute a material breach hereof and if such
         services are not resumed by User within a period of thirty (30) days
         after receipt of written notice from Pan American, Pan American shall
         have the right to terminate this Agreement with the same force and
         effect as a termination under Section 26 hereof.

27.3     The Port Authority has applied for and received a grant or grants of
         money from the Administrator of the Federal Aviation Administration
         pursuant to the Federal Airport Act of 1946 and pursuant to the Airport
         and Airway Development Act of 1970 (49 U.S.C. 1701), as the same have
         been amended and supplemented, and the Port Authority may in the future
         apply for and receive further such grants. Pan American under its
         Operating Agreement with the Port Authority for Teterboro Airport,
         dated September 19, 1967, has assumed certain obligations of the Port
         Authority under the Grant Agreement and in connection therewith, the
         Port Authority and Pan American may in the future undertake certain
         additional obligations respecting the operation of the Airport and the
         activities of contractors, lessees and permittees thereon. The
         performance by the User of the promises and obligations contained in
         this Agreement is therefore a special consideration and inducement to
         Pan American to enter into this Agreement and the User further
         covenants and agrees that if the Administrator of the Federal Aviation
         Administration or any other governmental officer or body having

                                       36
<PAGE>

         jurisdiction over the enforcement of the obligations of the Port
         Authority and/or Pan American in connection with Federal Airport Aid,
         shall make any orders, recommendations or suggestions respecting the
         performance by the User of its obligations under this Agreement, the
         User will promptly comply therewith, at the time or times when and to
         the extent that Pan American may direct.

28.      Survival of the Obligations of the User

28.1     In the event that the Agreement shall have been terminated in
         accordance with a notice of termination as provided in the Section
         entitled "Termination by Pan American" hereof, or in the event that Pan
         American has re-entered, regained or resumed possession of the Space in
         accordance with the provisions of the Section entitled "Right of
         Re-Entry" hereof, all the obligations of the User under this Agreement
         shall survive such termination or cancellation, re-entry, regaining or
         resumption of possession and shall remain in full force and effect for
         the full term of this Agreement, and the amount or amounts of damages
         or deficiency shall become due and payable to Pan American to the same
         extent, at the same time or times, and in the same manner as if no
         termination, cancellation, re-entry, regaining or resumption of
         possession had taken place. Pan American may maintain separate actions
         each month to recover the damage or deficiency then due or at its
         option and at any time may sue to recover the full deficiency less the
         proper discount, for the entire unexpired term of the Agreement.

28.2     The amount of damages for the period of time subsequent to termination
         or cancellation (or re-entry, regaining or resumption of possession) on
         account of the User's Fee obligations, shall be the sum of the
         following:

28.2.1   The amount of the total of all installments of basic fees pursuant to
         the Section entitled "Fees to Pan American" hereof, less the
         installments thereof payable prior to the effective date of termination
         except that the credit to be allowed for the installment payable on the
         first (1st) day of the month in which the termination is effective
         shall be prorated for the part of the month the Agreement remains in
         effect on the basis of the total days in the month;

28.2.2   An amount equal to all expenses incurred by Pan American in connection
         with regaining possession, restoring the Space, acquiring a User for
         the Space, legal expenses (including but not limited to attorneys'
         fees), putting the Space in order including, without limitation to,
         cleaning, redecorating (on failure of the User to restore), maintenance
         and brokerage fees.

29.      Use Subsequent to Cancellation or Termination

29.1     Pan American, upon termination or cancellation pursuant to the Section
         entitled "Termination by Pan American" of this Agreement, or upon any
         re-entry, regaining or resumption of possession pursuant to the Section
         entitled "Right of Re-Entry" of this Agreement, may occupy the Space or
         may enter into an agreement with another User and shall have the right
         to permit any person, firm or

                                       37
<PAGE>

         corporation to enter upon the Space and use the same. Such use may be
         of part only of the Space or of the entire Space or a part thereof,
         together with other space, and for a period of time the same as or
         different from the balance of the term hereunder remaining, and on
         terms and conditions the same as or different from those set forth in
         this Agreement. Pan American shall also, upon said termination or
         cancellation, or upon said re-entry, regaining or resumption of
         possession, have the right to repair and to make structural or other
         changes in the Space, including changes which alter the character of
         the Space and the suitability thereof for the purposes of the User
         under this Agreement, without affecting, altering or diminishing the
         obligations of the User hereunder. In the event either of use by others
         or of any actual use and occupancy by Pan American, there shall be
         credited to the account of the User against its survived obligations
         hereunder any net amount remaining after deducting from the amount
         actually received from any User, licensee, permittee or other occupier
         in connection with the use of the said Space or portion thereof during
         the balance of the term of use, and occupancy as the same is originally
         stated in this Agreement, or from the market value of the occupancy of
         such portion of the Space as Pan American may itself during such period
         actually use and occupy, less all expenses, costs and disbursements
         incurred or paid by Pan American in connection therewith. No such use
         and occupancy shall be or be construed to be an acceptance of a
         surrender of the Space, nor shall such use and occupancy constitute a
         waiver of any rights of Pan American hereunder. Pan American will use
         its best efforts to minimize damages to User under this Section
         commensurate with its obligations under the Basic Agreement.

30.      Remedies to be Non-Exclusive

30.1     Except where otherwise specifically provided, all remedies provided in
         this Agreement shall be deemed cumulative and additional and not in
         lieu of or exclusive of each other or of any other remedy available to
         either party at law or in equity.

31.      Limitation of Rights and Privileges Granted

31.1     No exclusive rights at the Airport are granted by this Agreement and no
         greater rights or privileges with respect to the use of the Space or
         any part thereof are granted or intended to be granted to the User by
         this Agreement, or by any provision thereof, than the rights and
         privileges expressly and specifically granted hereby.

32.      Removal of Personal Property

32.1     The User shall have the right at any time during the term of this
         Agreement to remove its equipment, inventories, removable fixtures and
         other personal property from the Space.

                                       38
<PAGE>

32.2     If the User shall fail to remove its property on or before the
         termination or expiration of the term, Pan American may remove such
         property to a public warehouse for deposit or retain the same in its
         own possession, and sell the same at public auction, the proceeds of
         which shall be applied first, to the expense of removal, storage and
         sale; second, to any sums owed by the User to Pan American, with any
         balance remaining to be paid to the User, but if the expenses of such
         removal, storage and sale shall exceed the proceeds of sale, the User
         shall pay such excess to Pan American upon demand.

33.      Brokerage

33.1     The User represents and warrants that no broker has been concerned on
         its behalf in the negotiation of this Agreement and that there is no
         such broker who is or may be entitled to be paid a commission in
         connection therewith. The User shall indemnify and save harmless Pan
         American of and from any claim for commission or brokerage made by any
         such broker when such claim is based in whole or in part upon any act
         or omission of the User.

34.      Notices

34.1     Except where expressly required or permitted herein to be oral, all
         notices, requests, consents and approvals required to be given to or by
         either party shall be in writing, and all such notices and requests
         shall be personally delivered to the duly designated officer or
         representative of such party or delivered to the office of such officer
         or representative during regular business hours, or forwarded to him or
         to the party at such address by registered mail.

35.      Construction and Application of Terms

35.1     The Section and subsection headings, if any, in this Agreement, are
         inserted only as a matter of convenience and for reference and in no
         way define, limit or describe the scope of intent of any provision
         hereof.

36.      Non-Liability of Individuals

36.1     Neither the Directors of Pan American or User nor any officers, agents
         or employees thereof, shall be charged personally by the other with any
         liability or held liable to the other under any term or provision of
         this Agreement, or because of its execution or attempted execution, or
         because of any breach or attempted or alleged breach thereof.

37.      Abatement

37.1     Except for abatement of fees set forth in Sections 5.2, 5.3, 5.4 and
         5.5 hereof, if at any time the User shall become entitled to abatement
         of Fees by the provisions of this Agreement or otherwise, the abatement
         of Fees shall be made on an equitable basis giving effect to the amount
         and character of the Space, the use of which is denied the User as
         compared with the entire Space.

                                       39
<PAGE>

38.      Port Authority Consent

38.1     This Agreement shall become effective upon the execution hereof by all
         parties hereto and the execution of a Consent Agreement between and
         among the Port Authority, Pan American, and User.

39.      Entire Agreement

         Exhibits A, B and C.

39.2     It constitutes the entire Agreement of the parties on the subject
         matter hereof. It may not be changed, modified, discharged or extended
         except by written instrument duly executed by Pan American and the
         User. The User agrees that no representations or warranties shall be

                           either the prior year's fee multiplied by a fraction,
                           the numerator of which shall be the CPI as published
                           for the month of December of the year prior to the

                           Space in the year 2009. In the event that such an
                           appraisal is performed, from and after January 1,
                           2010 the monthly fee payable by the User shall be the
                           greater of either (i) one twelfth of the appraised
                           building rate for Hangar 3 and Hangar 4 plus the
                           appraised land rate for Area 1 and 3, if Area 3 is
                           then a part of the Space or (ii) the December 2009
                           total monthly fee payable for Area 1 and 3 multiplied
                           by a fraction the numerator of which shall be the CPI
                           as published for the month of December 2009 and the
                           denominator of which shall be the CPI published for
                           the month of December 2008. In the event that the fee
                           calculated in accordance with (ii) above is fifteen
                           percent (15%) or higher than that calculated in
                           accordance with (i) above, then the monthly fee
                           payable effective January 1, 2010 would be the
                           greater of (a) the fee payable January 2000 adjusted
                           annually by 1/2 of the change in the CPI or (b) the
                           rate calculated per (i) above.

                  5.18.1   In the event that a real estate appraisal of the
                           User's Space is not performed in the year 2009,
                           effective January 1, 2010 the User shall pay to
                           Johnson Controls a total monthly fee for building and
                           land for Area 1 and Area 3, if then a part of the
                           Space, equal to the greater of either (i) the fee
                           payable December 1, 2009 multiplied by a fraction,
                           the numerator of which shall be the CPI as published
                           for the month of December 2009 and the denominator of
                           which shall be the CPI published for the month of
                           December 2008 or (ii) the rate payable December 1,
                           2009. In computing the total monthly fee payable in
                           no event shall the monthly fee be less than

                           the prior year's fee or increased by an amount
                           greater than six percent (6%).

                  5.19     Effective January 1, 2011 and annually thereafter the
                           User shall pay to Johnson Controls a total monthly
                           fee for building and land for Area 1 and Area 3, if
                           then a part of the Space, equal to the greater of (i)
                           the prior year's fee multiplied by a fraction, the
                           numerator of which shall be the CPI as published for
                           the month of December of the year prior to the
                           affected year and the denominator of which shall be
                           the CPI published for the month of December of two
                           years prior to the affected year, or (ii) the rate
                           payable December of the prior year. In computing the
                           total monthly fee payable in no event shall the
                           monthly fee be less than the prior year's fee or
                           increased by an amount greater than six percent (6%).

                  5.20     In the event that the term of the Agreement is
                           extended beyond the twenty (20) year anniversary of
                           the completion of the construction provided for in

                           based upon the appraised building rate derived from a
                           real estate appraisal performed of the facility, with
                           the appraiser to be selected by the Port Authority.
                           If an appraisal is not conducted the building rental
                           fee will be determined using the prevailing rate for
                           comparable space at the Airport or the existing rate
                           increased by the CPI, whichever is higher.

                  5.20.1   Effective on the January 1st following the twentieth
                           (20th) year anniversary of the Completion Date
                           described in Paragraph 3 of Supplement No. 4 of the
                           Agreement and annually thereafter, the User shall pay
                           to Johnson Controls the monthly building rental fee
                           stated above, multiplied by a fraction, the numerator
                           of which shall be the CPI as published for the month
                           of December of the year immediately preceding January

                           two years preceding. In computing the total monthly
                           fee payable in no event shall the monthly fee be less
                           than the year preceding."

                  minorities and five percent (5%) for firms owned and
                  controlled by women.

         2002, whichever occurs earlier and which will be known as the "Start
         Date", and for each and every calendar year thereafter, the Port
         Authority may ascertain the User's percentage share (hereinafter
         referred to as the "User's Current Fuel Share") of the total aircraft
         fuel gallons sold (hereinafter referred to as "Total Current Fuel
         Dispensed") at the Airport for the preceding calendar year. The fuel
         dispensed by the User for the year preceding the Start Date and the
         year preceding each and every calendar year thereafter during which
         such calculation is made shall be known as the "User's Current Fuel
         Dispensed". The User's Current Fuel Share shall be calculated by
         dividing the User's Current Fuel Dispensed by the Total Current Fuel
         Dispensed preceding the year during which such calculation is made. The
         User's Current Fuel Share for calendar year 1998 shall hereinafter be
         defined as "the Base Year Fuel Share" and is shown below:

         one-half percent (12.5%) or less of the User's Base Year Fuel Share,
         provided the Accommodation Space is not then covered by a sub-use or
         other agreement or at such other time as the Port Authority deems it is
         in the best interest of the Airport to restore the Accommodation Space
         to the User.

14.6.    The User agrees that all handling, sublease, sub-use and occupancy
         agreements shall be reasonable and at non-discriminatory rates, fees

         rata share of the User's costs of (1) operation and maintenance, (2)
         services provided, and (3) the User's fees and investment in the

                           Port Authority shall have no obligation to conduct

                  is understood and agreed that the Port Authority shall not be

                  or any costs in connection with the removal, restoration,
                  modification, correction or change required to cause such work

         (e)      The entire obligation of the Port Authority under this

         (f)      The User shall promptly submit to the Port Authority further
                  information, including but not limited to its estimate of the
                  amounts and times of the various payments it will be making
                  for Construction Costs as the Port Authority may from time to
                  time, and at any time, request, and shall be available itself
                  or cause its architect or engineer to be available for
                  consultation in connection with payment certificates submitted
                  pursuant to subparagraph (b) of this Paragraph.

                  to time by its agents, employees and representatives to audit
                  and inspect during regular business hours the books, records
                  and other data of the User relating to the cost of

                  the Construction Work, it being understood that the Port
                  Authority shall not be bound by any prior audit conducted by
                  it. The User agrees to keep such books, records and other data
                  within the Port of New York District. The User shall maintain
                  such books, records and other data for five (5) years after
                  the User has delivered the certificate marked "final" called
                  for under subparagraph (b) above.

         (h)      If the User has included in any portion of the cost of the
                  Construction work any item as having been incurred, but which
                  in the opinion of the Port Authority was not so incurred, or
                  which in the opinion of the Port Authority was not so incurred
                  is not an item properly chargeable to such element of cost
                  under sound accounting practice, or does not represent an
                  appropriate division of the costs of a particular contract
                  which are required to be designated according to time of
                  performance or delivery, and the parties have been unable to
                  resolve their differences within 90 days after the Port
                  Authority gave its notice objecting to the same, the Port

                  Authority an amount equal to the product obtained by
                  multiplying (A) the amount of each Subsequent Construction
                  Advance made on other than the last day of a month, and (B)
                  the number of days in the period from the date of such

                  the total of all Construction Advances made to the User
                  hereunder up to the time of such audit then, upon demand of
                  the Port Authority, the User shall immediately pay to the Port
                  Authority an amount equal to the difference between the
                  amounts expended by the User as disclosed by the Port
                  Authority audit and the aforesaid amount of the total of all
                  Construction Advances made to the User and effective from and
                  after such date of payment the Construction Advance Amount
                  shall be reduced by the amount of such payment and the Monthly
                  Additional Rental payable by the User adjusted appropriately
                  hereunder.

17.      The Port Authority may advance funds to the User for the construction
         of hangars. If Port Authority funds are provided to the User a security
         deposit in the form of any of the following will need to be provided:
         Cash, Letter of Credit, Treasury Bonds, Treasury Notes. The bonds can
         be issued by any of the following: States of New Jersey or New York or
         the Port Authority of New York and New Jersey. Security will be in the
         amount of one million dollars ($1,000,000) for each hangar to be
         constructed. If two hangars are being constructed simultaneously one
         million dollars will need to be provided to the Port Authority for each
         hangar for which funding is being provided. If the hangars are being
         constructed consecutively (only one is being constructed at a time),
         the one million dollar security from the first hangar can be rolled
         over to be used for the second. The security is only required during
         the construction period until a certificate of occupancy has been
         issued.

                                CONSENT AGREEMENT

         THIS AGREEMENT, dated as of October 15, 1999 by and among THE PORT
AUTHORITY OF NEW YORK AND NEW JERSEY (hereinafter called "the Port Authority")
and JOHNSON CONTROLS WORLD SERVICES INC. (hereinafter called the "Airport
Operator") and ATLANTIC AVIATION CORPORATION (hereinafter called "the User"),

                                 WITNESS, THAT:

         WHEREAS, the Port Authority and the Airport Operator have heretofore
entered into an agreement dated September 19, 1967 (which agreement, as the same
has been or may hereafter be supplemented and amended, is hereinafter called
"the Main Agreement"), pursuant to which the Airport Operator is operating and
using Teterboro Airport (hereinafter called "the Airport") and;

         WHEREAS, pursuant to and in accordance with the terms of the Main
Agreement, the Airport Operator and the User entered into a Use and Occupancy
Agreement dated February 14, 1979 with the consent of the Port Authority (which
consent was set forth in an agreement hereinafter called the "Consent
Agreement") which Use and Occupancy Agreement has been designated TA-121 and
hereinafter called "TA-121"; and

         WHEREAS, the Airport Operator and the User desire to execute a
Surrender Agreement which calls for the User, under certain conditions, to
surrender a portion of the Space associated with TA-121. A copy of which
Surrender Agreement is attached hereto, made a part hereof and hereafter called
"the Surrender Agreement", subject to the consent of the Port Authority and the
execution of a Consent Agreement by and among the Airport Operator, the User and
the Port Authority.

         NOW, THEREFORE, for and in consideration of the mutual agreements
herein contained, the Port Authority, the Airport Operator and the User hereby
agree effective as of the Effective Date of the Surrender Agreement as follows:

         1.       On the terms and conditions hereinafter set forth, the Port
                  Authority consents to the Surrender Agreement.

         2.       (a) If the Main Agreement shall terminate (whether through the
                  expiration of its term or by earlier termination as provided
                  in the Main Agreement) before the expiration date of the two
                  year period identified in the Surrender Agreement, if the User
                  is in occupancy of and using the "surrender space" identified
                  in the Surrender Agreement, the Surrender Agreement will be
                  terminated. Under these conditions, the User is obligated to
                  enter into another surrender agreement with the Port Authority
                  or a successor airport operator selected by the Port Authority
                  with the same terms and conditions of the Surrender Agreement,
                  and with such additional terms as may be necessary or
                  appropriate.

         3.       Neither this Consent Agreement, nor anything contained herein
                  nor the consent granted hereunder shall constitute or be
                  deemed to constitute a

                                     Page 1

<PAGE>

                  consent to nor shall they create an inference or implication
                  that there has been consent to any enlargement, variation or
                  change in the rights, powers and privileges granted to the
                  Airport Operator under the Main Agreement, nor consent to the
                  granting or conferring of any rights, powers or privileges to
                  the User as may be provided by TA-121 if not granted to the
                  Airport Operator under the Main Agreement, nor shall the same
                  impair or change any of the duties, liabilities and
                  obligations imposed on the Airport Operator under the Main
                  Agreement. The Surrender Agreement is an agreement between the
                  Airport Operator and the User with respect to the various
                  matters set forth therein. Neither this Consent Agreement nor
                  anything contained herein nor the consent granted hereunder
                  shall constitute an agreement between the Port Authority and
                  the Airport Operator that the provisions of Surrender
                  Agreement shall apply and pertain as between the Airport
                  Operator and the Port Authority, it being understood that the
                  terms, provisions, covenants, conditions and agreements of the
                  Main Agreement shall, in all respects, be controlling,
                  effective and determinative. The specific mention of or
                  reference to the Port Authority in any part of Surrender
                  Agreement, including, without limitation thereto, any mention
                  of any consent or approval of the Port Authority now or
                  hereafter to be obtained, shall not be or be deemed to create
                  an inference that the Port Authority has granted its consent
                  or approval thereto under this Consent Agreement or shall
                  thereafter grant its consent or approval thereto or that the
                  subject matter as to which the consent or approval applies has
                  been or shall be approved or consented to in principle or in
                  fact or that the Port Authority's discretion pursuant to the
                  Main Agreement as to any such consents or approvals shall in
                  any way be affected or impaired. The lack of any specific
                  reference in any provisions of the Surrender Agreement to Port
                  Authority approval or consent shall not be deemed to imply
                  that no such approval or consent is required and the Main
                  Agreement shall, in all respects, be controlling, effective
                  and determinative.

         4.       The granting of the consent hereunder by the Port Authority
                  shall not be or be deemed to operate as a waiver of consent to
                  any subsequent agreement with respect to the use or occupancy
                  of space at the Airport (by the Airport Operator or by the
                  User) or to any assignment of the Main Agreement or TA-121 or
                  of any rights under either of them, whether in whole or in
                  part.

         5.       Reference herein to the User shall mean and include the User,
                  its officers, agents, employees and also others on the Space
                  covered by TA-121 or elsewhere on the Airport with the consent
                  of the User.

         6.       Neither the Commissioners of the Port Authority nor any of
                  them, nor any officer, agent or employee thereof shall be held
                  personally liable to the Airport Operator or to the User under
                  any term of provision of this Consent Agreement or because of
                  its execution or because of any breach or alleged breach
                  hereof.

                             SUPPLEMENTAL AGREEMENT

         THIS AGREEMENT, dated this 23rd day of August, 2000 by and between THE
PORT AUTHORITY OF NEW YORK AND NEW JERSEY (hereinafter called the "Port
Authority") and ATLANTIC AVIATION CORPORATION, a corporation organized under the
laws of the State of Delaware (hereinafter called the "User"),

         WITNESSETH, THAT:

         WHEREAS, The Port Authority of New York and New Jersey (hereinafter
called "the Port Authority") is the owner of Teterboro Airport located in the
Boroughs of Teterboro, Moonachie and Hasbrouck Heights and in the Township of
Lyndhurst, County of Bergen in the State of New Jersey; and

         WHEREAS, Johnson Controls World Services Inc. (hereinafter called
"Johnson Controls") is the operator of Teterboro Airport and has the right to
operate and use the Airport as successor - assignee to an agreement between Pan
American World Airways, Inc. (hereinafter called "Pan American") and the Port
Authority dated September 19, 1967 (hereinafter called the "Basic Agreement");
and

         WHEREAS, a Use and Occupancy Agreement, bearing file No. TA-121 and
made effective as of February 14, 1979, was entered into between Pan American
and the User for the use and occupancy of certain Space at Teterboro Airport
(which Use and Occupancy Agreement is hereinafter referred to as "the
Agreement"); and

         WHEREAS, Johnson Controls and the Port Authority intend to terminate
the Basic Agreement effective as of the Termination Date, as hereinafter
defined; and

         WHEREAS, effective from and after the Termination Date the Port
Authority will be the operator of the Airport and now desires, together with the
User, to provide for the continuation of the Agreement and the substitution of
the Port Authority in the place and stead of Johnson Controls as the Airport
Operator under the Agreement;

         NOW, THEREFORE, in consideration of the mutual agreements and
respective promises herein contained and made by the parties hereto, the parties
hereby agree, as of the date first set forth above, as follows:

<PAGE>

         1.       The parties hereby agree that if, as and when the Basic
Agreement shall expire or be terminated, the Port Authority shall notify the
User of the effective date thereof, with such date set forth in said notice
being herein referred to as the "Effective Date." From and after the Effective
Date, the term of the Agreement shall continue as provided in the Agreement with
the Port Authority as the Airport Operator thereunder, with the Port Authority
succeeding to all the rights and obligations of Johnson Controls under the
Agreement from and after the Termination Date. The obligations and liabilities
of Johnson Controls to the User arising under the Agreement prior to the
Termination Date shall be and remain the obligations and liabilities of Johnson
Controls and the Port Authority shall have no responsibility therefore.

         2.       As between the Port Authority and the User, this substitution
of the Port Authority shall not in any way whatsoever affect or impair the
liability of Johnson Controls to the User or to the Port Authority to perform
all the terms, provisions and conditions of the Agreement on the part of Johnson
Controls to be performed, for the period from the effective date of the
Agreement to and including the Termination Date and the obligation to comply
with all requirements of the Port Authority and appropriate federal, state and
local governmental agencies arising from any environmental condition of the
Space.

         3.       From and after the Termination Date, the Port Authority shall
assume all the rights, obligations and duties of Johnson Controls under the
Agreement as well as the performance of, and does hereby agree to perform, all
the terms, provisions and conditions of the Agreement on the part of the Airport
Operator thereunder to be performed. The execution of this instrument by the
Port Authority does not constitute a representation by it that Johnson Controls
has performed or fulfilled every obligation required by the Agreement; as to
such matters the User agrees to look solely to Johnson Controls.

         4.       No provision of the Agreement, including but not limited to,
those imposing obligations on the User with respect to laws, rules, regulations,
taxes, assessments and liens, shall be construed as a submission or admission by
the Port Authority that the same could or does lawfully apply to the Port
Authority, nor shall the existence of any provision of the Agreement covering
actions which shall or may be undertaken by the User or the Airport Operator,
including but not limited to, construction on the Space covered by the
Agreement, be deemed to imply or infer that Port Authority consent or approval
thereto has been or shall be given or that Port Authority discretion with
respect thereto will in any way be affected or impaired. References in this
paragraph to specific matters and provisions shall not be construed as
indicating any limitation upon the rights of the Port Authority with respect to
its discretion as to matters and provisions in the Agreement which are not
specifically referred to herein.

         5.       Except as otherwise provided herein, during the remainder of
the term of the Agreement all the terms, provisions, covenants and conditions of
the Agreement shall be and continue in full force and effect.

         6.       Neither the Commissioners of the Port Authority nor any of
them, nor any officer, agent or employee thereof, shall be charged personally by
the User with any liability, or held liable to it under any term or provision of
this Supplemental Agreement, or because of its execution or attempted execution
or because of any breach thereof.

         7.       This Supplemental Agreement and the Agreement which it amends
constitute the entire agreement between the Port Authority and the User on the
subject matter, and may not be changed, modified, discharged or extended except
by instrument in writing duly executed on behalf of both the Port Authority and
the User.

         IN WITNESS WHEREOF, the parties hereto have executed these presents as

                  Warranty where the liability agreed or determined

6.5      MATTERS ARISING SUBSEQUENT TO THIS AGREEMENT

         The Seller shall not be liable for breach of any Seller's Warranty in
         respect of any matter to the extent that the same would not have
         occurred but for:

         6.5.1    any matter or thing done or omitted to be done pursuant to and
                  in compliance with this Agreement or otherwise at the request
                  in writing or with the approval in writing of the Purchaser;

                  of the Purchaser or any of the Group Companies introduced or
                  having effect after Closing.

6.6      RECOVERY FROM THIRD PARTIES FOLLOWING RECOVERY FROM THE SELLER

         If the Seller has paid an amount in discharge of any claim for breach
         of any Seller's Warranty and the Purchaser or any Group Company is
         entitled to recover (whether by payment, discount, credit, relief,
         insurance or otherwise) from a third party a sum which indemnifies or
         compensates the Purchaser or Group Company (in whole or in part) in
         respect of the loss or liability which is the subject matter of the
         claim, the Purchaser shall, or shall procure that the relevant Group
         Company shall, pay to the Seller as soon as practicable after receipt
         an amount equal to (i) any sum recovered from the third party less any
         costs and expenses incurred in obtaining such recovery less any
         Taxation attributable to the recovery after taking account of any tax
         relief available in respect of any matter giving rise to the claim or
         if less (ii) the amount previously paid by the Seller to the Purchaser
         less any Taxation attributable to it.

6.7      MITIGATION OF LOSSES

         The Purchaser shall procure that all reasonable steps are taken and all
         reasonable assistance is given to avoid or mitigate any Losses which in
         the absence of mitigation might give rise to a liability in respect of
         any claim for breach of any Seller's Warranty.

6.8      FRAUD

         None of the limitations contained in this Clause 6 shall apply to any
         claim which arises or is increased, or to the extent to which it arises
         or is increased, as the consequence of, or which is delayed as a result
         of, fraud or wilful concealment by the Seller or any of its directors,
         officers, employees or agents.

7        CLAIMS

7.1      NOTIFICATION OF POTENTIAL CLAIMS

                                       8

<PAGE>
         If the Purchaser becomes aware of any fact, matter or circumstance that
         may give rise to a claim against the Seller for breach of any Seller's
         Warranty, the Purchaser shall as soon as reasonably practicable give a
         notice in writing to the Seller setting out such information as is
         available to the Purchaser as is reasonably necessary to enable the
         Seller to assess the merits of the claim and shall use its reasonable
         endeavours to preserve such evidence as the Seller may consider
         necessary. Failure to give notice within such period shall not affect
         the rights of the Purchaser except to the extent that the Seller is
         prejudiced by the failure.

7.2      NOTIFICATION OF CLAIMS UNDER THIS AGREEMENT

         Notices of claims for breach of Seller's Warranty shall be given by the
         Purchaser to the Seller within the time limits specified in Clause 6.1,
         specifying in reasonable detail the legal and factual basis of the
         claim and the evidence on which the Purchaser relies and, if
         practicable, an estimate of the amount of Losses which are, or are to
         be, the subject of the claim (including any Losses which are contingent
         on the occurrence of any future event).

7.3      COMMENCEMENT OF PROCEEDINGS

         Any claim notified pursuant to Clause 7.2 shall (if it has not been
         previously satisfied, settled or withdrawn) be deemed to be irrevocably
         withdrawn twelve months after the notice is given pursuant to Clause
         7.2 or, in the case of any contingent liability, twelve months after
         such contingent liability becomes an actual liability and is due and
         payable unless legal proceedings in respect of it have been commenced
         by being both issued and served.

7.4      INVESTIGATION BY THE SELLER

         In connection with any matter or circumstance that may give rise to a
         claim against the Seller for breach of any Seller's Warranty:

         7.4.1    the Purchaser shall allow, and shall procure that the relevant
                  Group Company allows, the Seller and its financial, accounting
                  or legal advisers to investigate the matter or circumstance
                  alleged to give rise to a claim and whether and to what extent
                  any amount is payable in respect of such claim; and

         7.4.2    the Purchaser shall disclose to the Seller all material of
                  which the Purchaser is aware which relates to the claim and
                  shall, and shall procure that the relevant Group Company
                  shall, give, subject to their being paid all reasonable costs
                  and expenses, all such information and assistance, including
                  access to premises and personnel, and the right to examine and
                  copy or photograph any assets, accounts, documents and
                  records, as the Seller or its professional advisers may
                  reasonably request subject to the Seller agreeing in such form
                  as the Purchaser may reasonably require to keep all such
                  information confidential and to use it only for the purpose of
                  investigating and defending the claim in question.

7.5      CONDUCT OF THIRD PARTY CLAIMS

         If the matter or circumstance that may give rise to a claim against the
         Seller for breach of any Seller's Warranty is a result of or in
         connection with a claim by or liability to a third party then the
         Purchaser or other member of the Purchaser's Group shall, subject to
         the next sentence, be entitled, in its absolute discretion, to take
         such action as it shall deem necessary to avoid, dispute, deny, defend,
         resist, appeal, compromise or contest such claim or liability
         (including, without limitation, making counterclaims or other claims
         against third parties) but shall, so far as practicable, without
         prejudice to the rights of the insurers

                                       9

<PAGE>
         of the Purchaser's Group, consult with the Seller and with the
         Guarantor before taking any such action. No such claim shall be settled
         by the Purchaser without the prior written consent of the Guarantor.

8        GUARANTEE AND INDEMNITY

8.1      In consideration of the Purchaser entering into this Agreement, the
         Guarantor irrevocably and unconditionally:

         8.1.1    guarantees to the Purchaser the due and punctual performance
                  and discharge by the Seller of all its obligations and
                  liabilities (including without limitation the obligation to
                  pay money) under this Agreement and the Closing Documents
                  (together, the "GUARANTEED OBLIGATIONS") and agrees to pay on
                  demand from time to time each sum which the Seller is liable
                  to pay under this Agreement and the Closing Documents; and

         8.1.2    agrees, as an additional and independent obligation, that if
                  any of the Guaranteed Obligations are not recoverable from the
                  Guarantor under the guarantee in Clause 8.1.1 for any reason
                  the Guarantor will be liable to the Purchaser as a principal
                  debtor by way of indemnity for the same amount as that for
                  which it would have been liable had those Guaranteed
                  Obligations been recoverable and further agrees to discharge
                  that liability on demand from time to time.

8.2      The guarantee in Clause 8.1.1 shall be a continuing security until the
         performance and discharge in full of the Guaranteed Obligations.

8.3      The Guarantor's obligations to the Purchaser shall not be reduced,
         discharged, impaired or adversely affected by reason of:

         8.3.1    any time, indulgence, waiver or other concession which the
                  Purchaser may grant to the Seller or any other person;

         8.3.2    the insolvency, incapacity, lack of authority, death or
                  disability of the Seller or the Guarantor or of any person
                  purporting to act on behalf of either of them;

         8.3.3    any termination, amendment, variation, release, novation or
                  supplement of or to this Agreement or the terms of any of the
                  Guaranteed Obligations;

         8.3.4    any variation, extension, discharge or compromise of any right
                  or remedy which the Purchaser may now or hereafter have from
                  or against the Seller and any other person in respect of any
                  of the obligations and liabilities of the Seller and any other
                  person under and in respect of this Agreement;

         8.3.5    any act or omission by the Purchaser or any other person in
                  perfecting or enforcing any security, guarantee, assurance
                  against loss or indemnity present or future from or against
                  the Seller and any other person or any such security,
                  guarantee, assurance against loss or indemnity being
                  defective, void or unenforceable;

         8.3.6    any claim or enforcement of payment from the Seller and any
                  other person;

         8.3.7    any defect, irregularity, unenforceability, invalidity,
                  illegality, frustration or discharge by operation of law of
                  any of the obligations of the Purchaser or the Guarantor;

         8.3.8    any change of control of the Seller or the occurrence of any
                  circumstance affecting the liability of the Seller to
                  discharge any Guaranteed Obligations;

                                       10

<PAGE>
         8.3.9    any security given or payment made to the Purchaser by the
                  Seller or any other person being avoided or reduced under any
                  law (whether English or foreign) relating to bankruptcy,
                  liquidation or analogous circumstances in force from time to
                  time;

         8.3.10   any change in the Seller's or the Guarantor's constitution or
                  any statutory or other compromise or arrangement with
                  creditors affecting the Seller; or

         8.3.11   any act or omission which would not have discharged or
                  affected the obligations of the Guarantor had it been a
                  principal debtor instead of a guarantor.

8.4      The obligations and liabilities expressed to be undertaken by the
         Guarantor under the guarantee in Clause 8.1.1 are those of primary
         obligor and not merely as a surety.

8.5      The Purchaser shall not be obliged before taking steps to enforce any
         of its rights and remedies under the guarantee in Clause 8.1.1:

         8.5.1    to take action or obtain judgment in any court against the
                  Seller and any other person;

         8.5.2    to make or file any claim in a bankruptcy, liquidation,
                  administration or insolvency of the Seller and any other
                  person; or

         8.5.3    to make demand, enforce or seek to enforce any claim, right or
                  remedy against the Seller and any other person.

8.6      The guarantee in Clause 8.1.1 shall be in addition to any other
         security, guarantee, assurance against loss or indemnity held by the
         Purchaser at any time from the Seller or any other person and shall not
         merge with or prejudice or be prejudiced by any security, guarantee,
         assurance against loss or indemnity or any other contractual or legal
         rights of the Purchaser.

8.7      Any settlement or discharge in whole or in part by the Purchaser of the
         Guaranteed Obligations shall be deemed to be given or made on condition
         that it shall be of no effect as a settlement or discharge if the
         assurance, security or payment on the faith of which it was made shall
         afterwards be avoided, set aside or ordered to be refunded by virtue of
         any law (whether English or foreign) relating to bankruptcy,
         liquidation or analogous circumstances in force from time to time or
         for any other reason so that at any time after such avoidance, setting
         aside or order for refund the Purchaser shall be entitled to exercise
         its rights under the guarantee in Clause 8.1.1 as if no such settlement
         or discharge had been made.

8.8      All payments by the Guarantor shall be made in immediately available
         funds to the credit of such account as the Purchaser may designate and
         in full without any set-off, counterclaim or other deduction. If any
         such deduction is so required, the Guarantor shall simultaneously pay
         to the Purchaser such amount as is necessary to ensure that the
         Purchaser receives a net sum equal to what it would have received had
         no deduction been made.

8.9      No claim may be made against the Guarantor pursuant to this Clause 8
         more than three years after the date of this Agreement, or, in the case
         of a claim related to any Seller's Warranty in Schedule 7 given
         pursuant to Clause 10.15, more than three years after the date on which
         the relevant Seller's Warranty is given.

                                       11
<PAGE>

8.10     The aggregate liability of the Guarantor pursuant to this Clause 8
         shall not exceed the aggregate of the consideration paid for the Shares
         pursuant to Clause 3 and, if the Call Option is exercised pursuant to
         Clause 10.15, the consideration paid by the Purchaser for the relevant
         Retained Shares pursuant to Clause 10.15.

                  exercise all voting and other rights in relation to the Shares
                  and, if applicable, the Retained Shares in accordance with the
                  Purchaser's Instructions.

10.2     WHOLE AGREEMENT

         10.2.1   This Agreement contains the whole agreement between the
                  parties relating to the sale of the Shares and, If applicable,
                  the Retained Shares at the date of this Agreement to the
                  exclusion of any terms implied by law which may be excluded by
                  contract and supersedes any previous written or oral agreement
                  between the parties in relation to the matters dealt with in
                  this Agreement.

         10.2.2   The Purchaser acknowledges that it has not been induced to
                  enter this Agreement by any representation, warranty or
                  undertaking not expressly incorporated into it.

         10.2.3   So far as is permitted by law and except in the case of fraud,
                  each of the Seller and the Purchaser agrees and acknowledges
                  that its only right and remedy in relation to any
                  representation, warranty or undertaking made or given in
                  connection with this Agreement shall be for breach of the
                  terms of this Agreement to the exclusion of all other rights
                  and remedies (including those in tort or arising under
                  statute).

10.3     ASSIGNMENT

         10.3.1   Each of the Seller and the Guarantor agrees that the benefit
                  of every provision in this Agreement is given to the Purchaser
                  for itself and its successors in title and assigns.
                  Accordingly, the Purchaser (and its successors and permitted
                  assigns) may, without the consent of the Seller or of the
                  Guarantor, assign to the beneficial owner for the time being
                  of the Shares and, if applicable, the Retained Shares the
                  benefit of all or any of the Seller's and the Guarantor's
                  obligations under this Agreement, and/or any benefit arising
                  under or out of this Agreement, provided that the assignee
                  shall not be entitled to receive under this Clause any greater
                  amount than that to which the Purchaser would have been
                  entitled.

         10.3.2   Each of the Seller and the Guarantor agrees that, upon the
                  request of the Purchaser or its successors in title or
                  permitted assigns, this Agreement may be novated (in whole but
                  not in part) in favour of the beneficial owner for the time
                  being of the Shares and, if applicable, the Retained Shares
                  and the Seller and the Guarantor shall execute a novation
                  agreement in terms to be agreed at the time between the
                  Seller, the Purchaser and the Guarantor.

10.4     THIRD PARTY RIGHTS

         10.4.1   A person who is not a party to this Agreement has no right
                  under the Contracts (Rights of Third Parties) Act 1999 to
                  enforce any term of, or enjoy any benefit under, this
                  Agreement, except to the extent set out in this Clause 10.4.

<PAGE>
         10.4.2   A Group Company (whilst the Group Company remains in the
                  Purchaser's Group) may enforce and rely on Clause 5.3 to the
                  same extent as if it were a party.

         10.4.3   This Agreement may be terminated and any term may be amended
                  or waived without the consent of any Group Company.

10.5     VARIATION

         No variation of this Agreement shall be effective unless in writing and
         signed by or on behalf of each of the parties.

10.6     METHOD OF PAYMENT

         Wherever in this Agreement provision is made for the payment by one
         party to the other, such payment shall be effected by crediting for
         same day value the account specified by the payee to the payer
         reasonably in advance and in sufficient detail to enable payment by
         telegraphic or other electronic means to be effected on or before the
         due date for payment.

10.7     COSTS

         Each party shall bear its own costs in connection with the preparation,
         negotiation and entry into of this Agreement and the sale of the Shares
         and, if applicable, the Retained Shares.

10.8     INTEREST

         If a party to this Agreement defaults in the payment when due of any
         sum payable under this Agreement, its liability shall be increased to
         include interest on such sum from the date when such payment is due
         until the date of actual payment (after as well as before judgment) at
         a rate per annum of two per cent above the base rate from time to time
         of Barclays Bank PLC. Such interest shall accrue from day to day and
         shall be compounded monthly.

10.9     GROSSING-UP OF INDEMNITY PAYMENTS, VAT

         10.9.1   Where any payment is made under this Agreement pursuant to an
                  indemnity, compensation or reimbursement provision (including
                  for the avoidance of doubt any claim pursuant to Clauses 5, 7
                  or 8) and that sum is subject to a charge to Taxation in the
                  hands of the recipient (other than Taxation attributable to a
                  payment being properly treated as an adjustment to the
                  consideration paid by the Purchaser for the Shares) the sum
                  payable shall be increased to such sum as will ensure that
                  after payment of such Taxation (and after giving credit for
                  any tax relief available to the recipient in respect of the
                  matter giving rise to the payment) the recipient shall be left
                  with a sum equal to the sum that it would have received in the
                  absence of such a charge to taxation.

         10.9.2   Where under the terms of this Agreement one party is liable to
                  indemnify or reimburse another party in respect of any costs,
                  charges or expenses, the payment shall include an amount equal
                  to any VAT thereon not otherwise recoverable by the other
                  party, subject to that party using all reasonable endeavours
                  to recover such amount of VAT as may be practicable.

         10.9.3   If any payment under this Agreement constitutes the
                  consideration for a taxable supply for VAT purposes, then in
                  addition to that payment the payer shall pay any VAT due.

10.11 INVALIDITY

         10.11.1  If any provision in this Agreement shall be held to be

                                       15
<PAGE>
                  or modification is necessary so that the provision is legal,
                  valid and enforceable and gives effect to the commercial
                  intention of the parties.

         10.11.2  To the extent it is not possible to delete or modify the

                  venue or on the ground that proceedings have been brought in
                  an inconvenient forum.

                                       16

<PAGE>
         10.15.1  The Seller hereby grants the Purchaser, in consideration of
                  the Purchaser's execution of this Agreement, a call option
                  (the "CALL OPTION") over the Retained Shares, upon the terms
                  of this Clause 10.15.

         10.15.2  The Call Option may be exercised by the Purchaser by notice in
                  writing to the Purchaser served at any time up to and
                  including 31 December 2004.

         10.15.3  The Call Option may be exercised either in respect of all the
                  Retained Shares at the same time, or in two separate tranches
                  of 4,107,000 Retained Shares and 9,712,500 Retained Shares
                  each.

         10.15.4  The price payable by the Purchaser on exercise of the Call
                  Option shall be an amount in cash equal to (pound)1 per
                  Retained Share the subject of the exercise of the Call Option
                  plus an amount calculated as follows:

                          (A x 12% x (T)/365) - (B + C)

                  where:

                  A = (pound)2 x the number of Retained Shares the subject of
                  the exercise of the Call Option;

                  B = the amount of interest on P, calculated in accordance with
                  the terms of the Existing Loan Note Instrument, for the period
                  comprised in T;

                  C = the amount of any dividends paid by the Company in the
                  period comprised in T in respect of the Retained Shares the
                  subject of the exercise of the Call Option;

                  P = the nominal amount of Existing Loan Notes equal to the
                  nominal value of the Retained Shares the subject of the
                  exercise of the Call Option; and

                  T = the number of days elapsed from (and including) 30 April
                  2004 to (but excluding) the date of completion of the transfer
                  of Shares by the Seller to the Purchaser (or as it may direct)
                  upon exercise of the Call Option.

         10.15.5  The transfer of Retained Shares shall take place within five
                  Business Days after exercise of the Call Option at such place
                  as the Purchaser and the Seller may agree. On that transfer,
                  the Purchaser shall pay the Seller the Call Option price for
                  the relevant Retained Shares. Against that payment, the Seller
                  shall execute, and deliver to the Purchaser or as it may
                  direct, a duly executed stock transfer form in respect of the
                  relevant Retained Shares in favour of the Purchaser or as it
                  may direct accompanied by the relative share certificate.

         10.15.6  The provisions of Clauses 2.2 and 2.3 shall apply to the sale
                  of Retained Shares, as if the references in them to Shares
                  were to Retained Shares and to Closing were to the date of
                  transfer of the Retained Shares.

         10.15.7  On the transfer of Retained Shares to the Purchaser, the
                  Seller shall be deemed to represent and warrant to the
                  Purchaser that the statements set out in Schedule 7 are true
                  and accurate and not misleading as of the date of that
                  transfer.

         10.15.8  While the Call Option remains exercisable the Seller shall not
                  create any Encumbrance on, or dispose of, the Retained Shares
                  or any interest in them except in accordance with this Clause.

<PAGE>
         10.15.9  On the transfer of Retained Shares pursuant to this Clause
                  10.15, the Purchaser shall also subscribe for New Loan Notes
                  with a nominal amount equal to the nominal value of the
                  Retained Shares being transferred at that time. On receipt of
                  the proceeds of that subscription, the Company shall forthwith
                  repay the same nominal amount of Existing Loan Notes.

         10.15.10 The Purchaser may not exercise the Call Option in respect of
                  all the Retained Shares or in respect of the tranche of
                  9,712,500 of the Retained Shares unless and until debt or
                  equity securities of Macquarie Infrastructure Assets Trust are
                  admitted to trading on an investment exchange.

         10.15.11 The Seller agrees with the Purchaser, in consideration for the
                  Purchaser's execution of this Agreement, not to sell, transfer
                  or otherwise dispose of any interest that it may have in any

                                 (CLAUSE 5.1.4)

The following are the persons referred to in Clause 5.1.4:

Andrew Hunter

                                   SCHEDULE 5
                                  (CLAUSE 5.2)

The following matters are disclosed for the purpose of Clause 5

1        On 7 November 2003, Pipeway Limited, then a subsidiary of Southern
         Utilities (Holdings) Limited (formerly Saur Water Services plc), was
         sold to an unconnected third party by Southern Utilities (Holdings)
         Limited for (pound)1.35 million.

2        On 29 February 2004, Optimum Information Services Limited transferred
         its business and assets to South East Water Limited.

3        On 8 January 2004, South East Water Limited and the Guarantor entered
         into an agreement for the provision by the Guarantor of financial and
         corporate strategy advice for a charge of (pound)2.4 million per annum.

4        South East Water Limited is in dispute with one of its contractors.
         Thus far, there has been exchange of correspondence with the threat of
         litigation from the contractor, but no proceedings have as yet been
         issued. The contractor alleges breaches of procurement rules in
         relation to the award of a contract in 2001 and is claiming loss of
         profit and bid costs of just over (pound)5 million. The management of
         South East Water Limited are confident there is no legitimate basis to
         this claim.

5        South East Water Limited has entered into two capital commitments in
         excess of(pound)1 million since 1 October 2003, being:

5.1      in relation to the Bewil-Darwell link, with a value of(pound)4.3
         million; and

5.2      in relation to the Cowbeech Water Treatment Works project, with a value
         of(pound)2.4 million.

6        A former employee of South East Water Limited has alleged false
         reporting of a failure of chlorination at Beenham Heath Treatment Works
         in November 1999. Management of South East Water Limited have
         investigated the claim and are confident that there is no legitimate
         basis to it.

7        The two issued shares in Southern Utilities Limited (a dormant company)
         are registered in the name of Margaret Devlin (Managing Director of
         South East Water Limited) and Geoffrey Hoskins (formerly Deputy
         Chairman of South East Water Limited). They are to be transferred to
         Southern Utilities (Holdings) Limited shortly after Closing.
