     3.   Lessor will pay all expenses related to the operation of the Aircraft
          when incurred, and will provide an invoice and bill Lessee for the

          the invoice and bill therefor.

     4.   Lessee will provide Lessor with requests for flight time and proposed
          flight schedules as far in advance of any given flight as possible,
          and in any case, at least twenty-four (24) hours in advance of
          Lessee's planned departure.  Requests for flight time shall be in a
          form whether written or oral, mutually convenient to, and agreed upon
          by the parties.  In addition to the proposed schedules and flight
          times Lessee shall provide at least the following information for each
          proposed flight at some time prior to scheduled departure as required
          by the Lessor or Lessor's flight crew:

          (a)  proposed departure point;

          (b)  destination;

          (c)  date and time of flight;

          (d)  the number of anticipated passengers;

          (e)  the nature and extent of luggage and/or cargo to be carried;

          (f)  the date and time of return flight, if any; and

          (g)  any other information concerning the proposed flight that may be
               pertinent or required by Lessor or Lessor's flight crew.

     5.   Lessor shall have final authority over the scheduling of the Aircraft,
          provided, however, that Lessor will use its best efforts to
          accommodate Lessee's needs and to avoid conflicts in scheduling.

     6.   Lessor shall be solely responsible for securing maintenance,
          preventive maintenance and required or otherwise necessary inspections
          on the Aircraft, and shall take such requirements into account in
          scheduling the Aircraft.  No period of maintenance, preventative
          maintenance or inspection shall be delayed or postponed for the
          purpose of scheduling the Aircraft, unless said maintenance or

                                       2
<PAGE>

          inspection can be safely conducted at a later time in compliance with
          all applicable laws and regulations, and within the sound discretion
          of the pilot in command.  The pilot in command shall have final and
          complete authority to cancel any flight for any reason or condition
          which in his judgment would compromise the safety of the flight.

     7.   Lessor shall employ, pay for and provide to Lessee a qualified flight
          crew for each flight undertaken under this Agreement.

     8.   In accordance with applicable Federal Aviation Regulations, the
          qualified flight crew provided by Lessor will exercise all of its
          duties and responsibilities in regard to the safety of each flight
          conducted hereunder.  Lessee specifically agrees that the flight crew,
          in its sole discretion, may terminate any flight, refuse to commence
          any flight, or take other action which in the considered judgment of
          the pilot in command is necessitated by considerations of safety.  No
          such action of the pilot in command shall create or support any
          liability for loss, injury, damage or delay to Lessee or any other
          person.  The parties further agree that Lessor shall not be liable for
          delay or failure to furnish the Aircraft and crew pursuant to this
          Agreement when such failure is caused by government regulation or
          authority, mechanical difficulty, war, civil commotion, strikes or
          labor disputes, weather conditions, or acts of God.

     9.   At all times during the term of this Lease, Lessor shall cause to be
          carried and maintained, at Lessor's cost and expense, physical damage
          insurance with respect to the Aircraft in the amount set forth below:

          Aircraft Physical Damage           $5,650,000.00
          (No Deductible While
          In Motion or Not in Motion)

          At all times during the term of this Lease, Lessor shall also cause to
          be carried and maintained, at Lessor's cost and expense, third party
          aircraft liability insurance, passenger legal liability insurance,
          property damage liability insurance, and medical expense insurance in
          the amounts set forth below:

          Combined Liability Coverage for
          Bodily Injury and Property Damage
          Including Passengers -

          Each Occurrence                    $100,000,000.00

          Medical Expense Coverage -
          Each Person                        $5,000.00

     Lessor shall also bear the cost of paying any deductible amount on any
policy of insurance in the event of a claim or loss.

                                       3
<PAGE>

     Any policies of insurance carried in accordance with this Lease:  (i) shall
name Lessee as an additional insured; and (ii) shall contain a waiver by the
underwriter thereof of any right of subrogation against Lessee; and (iii) shall
provide that in respect of the interests of Lessee, such policies of insurance
shall not be invalidated by any action or inaction of Lessor or any other person
and shall insure Lessee (subject to the limits of liability and war risk
exclusion set forth in such policies) regardless of any breach or any violation
of any warranty, declarations or conditions contained in such policies by Lessor
or any other person; and (iv) shall provide that if the insurers cancel
insurance for any reason whatsoever, or the same is allowed to lapse for non-
payment of premium, or if there is any material change in policy terms and
conditions, such a cancellation, lapse or change shall not be effective as to
Lessee.  Each liability policy shall be primary without right of contribution
from any other insurance which is carried by Lessee or Lessor and shall
expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured.

     Lessor shall submit this Lease for approval to the insurance carrier for
each policy of insurance on the aircraft.  Lessor shall arrange for a
Certificate of Insurance evidencing appropriate coverage as to the Aircraft and
the satisfaction of the requirements set forth above to be given by its
insurance carriers to Lessor.

     10.  Lessee warrants that:

          (a)  It will use the Aircraft for and on account of its own business
               only, and will not use the Aircraft for the purpose of providing
               transportation of passengers or cargo in air commerce for
               compensation or hire;

          (b)  It shall refrain from incurring any mechanics or other lien in
               connection with inspection, preventative maintenance, maintenance
               or storage of the Aircraft, whether permissible or impermissible
               under this Agreement, nor shall there be any attempt by any party
               hereto to convey, mortgage, assign, lease or any way alienate the
               Aircraft or create any kind of lien or security interest
               involving the Aircraft or do anything or take any action that
               might mature into such a lien; and

          (c)  During the term of this Agreement, it will abide by and conform
               to all such laws, governmental and airport orders, rules and
               regulations, as shall from time to time be in effect relating in
               any way to the operation and use of the Aircraft by a timesharing
               Lessee.

     11.  For purposes of this Agreement, the permanent base of operation of the
          Aircraft shall be Spartanburg, SC.

     12.  Neither this Agreement nor any party's interest herein shall be
          assignable to any other party whatsoever.  This Agreement shall inure
          to the benefit of and be binding upon the parties hereto, their heirs,
          representatives and successors.
