exercise and has properly given written notice of the exercise of its
option to sublease the premises for a period beginning June 1, 1998,

rental rate for the term beginning June 1, 1998, and expiring on May 31,
1999, only. Any additional option terms, if so exercised, and the rental
rates therefor, shall be addressed in subsequent amendments.

     WHEREAS, the Authority and Sublessee mutually desire to amend

amended.

     NOW, THEREFORE, for and in consideration of the premises herein set
forth and the terms and conditions hereinafter stated, the Authority and
Subleasee agree to and hereby do amend said Sublease Agreement dated June
1, 1992, as amended, as follows, to-wit:

     1. Delete paragraph 4 in its entirety and insert the following in lieu
thereof:

     Paragraph 4. Rental. Sublessee shall pay for the use and occupancy of
the premises for the terms beginning June 1, 1998, and extending through
May 31, 1999, the sum of One Hundred Seventy-Five Thousand and 00/100
Dollars ($175,000,00); payable in equal monthly payments of Fourteen
Thousand Five Hundred Eighty-three and 33/100 Dollars ($14,583.33).
Provided, however, Two Thousand One Hundred Twenty-five and 00/100 Dollars
($2,125.00) of the monthly payment for the twelve (12) months of said
one-year term shall be deferred upon the following condition: the total
amount deferred, Twenty-five Thousand Five Hundred and 00/100 Dollars
($25,500.00), less any amounts attributable to improvements made by
Sublessee prior to May 31, 1999, and which have not been previously
deducted from rental obligations pursuant to this Agreement shall be paid
to Sublessor in a lump-sum prior to May 31, 1999. Paid receipt
documentation for improvements shall be provided to Sublessor.

     Sublessee shall not be liable to the Sublessor for any additional
charge for purchase or sale of fuel made while utilizing the premises
should Sublessee determine, at its option, to purchase or resale fuel,
delivered from any Fixed Base Operations resident and operating on
Sublessor's premises. Said Fixed Base Operations shall be responsible for
payment of any and all appropriate funds, based on the Sublessee's
published sales price to the Sublessee's customers and in effect at the
time of delivery.

     Should no resident Fixed Base Operations be agreeable to selling fuel
to Sublessee on the Sublessor's premises and the Sublessee elects to sell
fuel on the subleased premises, then and if the sale of fuel is permitted
on the subleased premises, by applicable Federal and State law, then and
only in such an event, said Sublessee shall pay to the Sublessor a sum
equal to that charged other Fixed Base Operations on all fuel sold on the
subleased premises. Sublessee agrees that the additional rental called for
herein will be paid on all fuel used in connection with refueling
operations on all aircraft.

     Sublessee agrees to keep complete and accurate records of all fuel
sold by Sublessee on the subleased premises during the term of this
Sublease or any extension thereof and Sublessee shall on or before the 25th
day of each and every month provide the Sublessor with written notice of
such fuel sales together with the payment required by the subparagraph
above. In addition. Sublessee shall, on or before the 25th day of June of
each lease year provide the Sublessor with a certified statement of fuel
sold during the immediately preceding lease year together with any fuel
fees due to the Sublessor for that period.

     The Sublessor shall have the right on upon an annual basis, written
notice to the Sublessee to increase the fuel fees, provided however, such
increase shall apply to all Fixed Base Operations uniformly.

     2. The effective date of this amendment shall be June 1, 1998.

     3. All other terms and provisions of said Sublease Agreement dated
June 1, 1992, as amended, shall remain of full force and effect.
