                                    SUBLEASE

     THIS SUBLEASE is made this ________ of _____________________, 2000, between
WYOMING ASSOCIATES, INC., a South Carolina corporation, ("Tenant"), and ESA
SERVICES, INC. ("Subtenant").

                                    RECITALS

     1.  Tenant is the Tenant of the property commonly known as Kensington
Drive, Spartanburg, South Carolina (the "Building" or the "Premises").  Tenant
is the assignee of the interest of Johnson Development Associates, Inc., as
tenant under an Agreement from The City of Spartanburg ("Landlord") ("Underlying
Lease"), a copy of which is attached hereto as "Exhibit A".

     2.  Subtenant desires a sublease for the use of sufficient space (the
"Sublease Premises") to park one Challenger (N333GJ) aircraft (the "Aircraft")
within the Premises at a location reasonably designated by Tenant from time to
time (the "Sublease Premises") pursuant to the terms and conditions contained in
this Sublease ("Sublease").  In addition, Subtenant shall be entitled to
nonexclusive reasonable use of the restroom facilities, crew accommodations,
office space, kitchen and conference room by its employees, pilots and mechanic
as provided herein and provided such use does not unreasonably interfere with
Tenant's use thereof.  Other subtenants shall share space in and on the Premises
with Subtenant.  Its interests shall not be exclusive.

     3.  Tenant for itself and/or its other subtenants shall use the balance of
the Premises.

     In consideration of the mutual covenants, conditions and agreements
contained herein, the parties agree as follows:

                                   SECTION ONE
                        DESCRIPTION OF SUBLEASE PREMISES

     Tenant shall demise to Subtenant the Sublease Premises, as described in
Paragraph 2 above. Subtenant agrees to lease the Sublease Premises in an "as is"
condition, except as otherwise expressly set forth herein, provided that Tenant,
and not Subtenant, shall have complete responsibility for the condition of, and
any repair cost related to, the Sublease Premises and the Premises, except for
damage caused by Subtenant, its agents, servants, visitors, invitees, guests or
licensees and in the event of any and all violations of any local, state and/or
federal environmental hazardous waste laws, rules and regulations that exist as
of the date of this Sublease and/or are not introduced to the Premises by the
Subtenant, its agents, servants, visitors, invitees, guests or licensees.

                                   SECTION TWO
                               PURPOSE OF SUBLEASE

     The Sublease Premises demised under this Sublease shall be used by
Subtenant for aircraft hanger purposes for the storage of the Aircraft, for
conducting maintenance on the Aircraft and uses related thereto and for no other
purposes. Subject to Section 25, Subtenant
<PAGE>

may hire outside vendors for aircraft and hanger maintenance services other than
those required to be provided by Tenant hereunder and shall not be obligated to
use Tenant or vendors provided by Tenant for such maintenance services.

                                 SECTION THREE
                         TERM OF SUBLEASE; RENEWAL TERM

     The term of this Sublease shall be ten (10) years commencing upon
completion of the Premises Improvements and terminating on December 31, 2009.
Subject to the provisions below, Subtenant shall have the option of extending
this Sublease for two (2) successive five year periods (each an "Extension
Term") upon written notice delivered to Tenant not less than 180 days prior to
the end of the current term or Extension Term unless terminated sooner as
provided herein or under the Underlying Lease.  Termination or expiration of the
term of the Underlying Lease shall also extinguish this Sublease, provided that
in the event of a monetary breach of the Underlying Lease by Tenant or its
assignor, Subtenant shall have the right to cure such breach within thirty (30)
days of notice thereof, and further provided that the amounts paid to Landlord
to cure any such breach may be deducted from the rent payable hereunder.  If the
Term of the Underlying Lease expires, any applicable Extension Term shall
terminate concurrently.

                                  SECTION FOUR
                                      RENT

     During the initial term and any Extension Term of this Sublease, Subtenant
shall pay to Tenant Two Thousand Nine Hundred and no/100 ($2,900.00) Dollars per
month (subject to adjustments as provided below) payable on the first day of the
term of the Sublease and on the first day of each subsequent month as complete
and full rent for the Sublease Premises. Any other sums due as additional rental
under the provisions of this Sublease if any shall constitute rent and be due on
the basic rental payment due date first occurring after notice and invoice from
Tenant. All such payments shall be paid to Landlord without set off except as
provided in Section 3.

     The monthly rental payments shall increase on the same dates as the rent
increases go into effect under their underlying Agreement with the City of
Spartanburg. The increase paid by each Subtenant shall be in proportion to the
percentage increase of the underlying Agreement. Each Subtenant shall pay its
proportionate share of the cost of operating the Premises (as defined in Section
5 below) as "Additional Rent".

                                  SECTION FIVE
                                ADDITIONAL RENT

     Tenant shall pay and maintain records of payment of public liability and
property damage insurance, and the costs of common area maintenance on the
Premises and shall on an annual basis present statements of account on the same
expenses and collect from Subtenant, as Additional Rent, as then existing.
Subtenant's share of common area maintenance expenses shall be proportional
based on the number of pilots and personnel associated with the aircraft fleet
of Subtenant. The proportion may change based on changes in the type, size and

                                       2
<PAGE>

requirements of the aircraft fleet and the number of personnel associated with
the aircraft fleet. TENANT SHALL CONTRIBUTE $950.00 PER MONTH AS ADDITIONAL
RENT. Additional Rent shall be made with each monthly Rent payment. Adjustment
in the monthly Additional Rent payment shall be made by March 1, based on the
actual expenditures of the preceding twelve month period. If the amount
collected does not equal the actual expenditures, adjustment shall be made
annually as required within thirty (30) days of Tenant's rendering of account.

     For purposes of this paragraph, "Common Area Maintenance Expense" shall
include all costs and expenditures incurred by Tenant in maintaining and
operating refuse collection facilities and removal; parking lot and tarmac
sweeping and snow removal; parking lot and tarmac repairs and maintenance
including patching, resurfacing and repainting; common area lighting
maintenance, security; sidewalk cleaning; landscaping maintenance and repair,
including replacing and renovation of plant material; irritation associated
expenses; personnel expenses associated with the above functions.  Tenant may
enter into reasonable contracts for the execution of these common area
maintenance functions.

     The Premises are owned by the City of Spartanburg.  As they are publicly
owned, they should be exempt from ad valorem taxation.  However, should the
Premises become subject to ad valorem taxation, the amount of such taxes shall,
for purposes of this Section, be included as a common area expense and shall be
collected proportionately from Subtenant as Additional Rent.

                                   SECTION SIX
                       CASUALTY DAMAGE OR INJURY INSURANCE
                            AND WAIVER OF SUBROGATION

     1.  If the Sublease Premises shall be destroyed or damaged by any acts of
war, the elements, including earthquake, fire damage or other casualty, to such
extent as to render the Sublease Premises untenantable in whole or in
substantial part, either the Tenant or the Subtenant shall have the right to
declare this Sublease terminated upon written notice to the other.  Subtenant
shall not have the option of terminating this Sublease if Subtenant's storage of
the Aircraft with the Building is not interrupted for more than forth-five (45)
days.  In the event any such destruction or damage occurs and this Sublease is
not terminated as permitted herein, Subtenant's rental obligations in this
Sublease shall be abated pro rata during the time that such destruction or
damage occurs and thereafter until the repair thereof is substantially
completed.

     2.  At all times during the term of this Sublease, Subtenant shall maintain
in full force and effect, at its sole cost, one or more policies of insurance,

               value of the Aircraft(s) located at the Sublease Premises,
               including a waiver of subrogation in favor of the Tenant and
               Tenant's insurer; with deductible being the sole responsibility
               of Subtenant.

name Tenant, its Manager, officers, directors, members, employees, and agents as

a severability of interest, insuring contractual liability; and providing the

inaction or breach of warranty on the part of the insured.

the other and their employees, officers, directors, manager, members and agents,
successors and assigns from and against any and all losses, damages, claims,
suits or actions, judgments, and costs, including reasonable attorneys' fees,

<PAGE>

Premises or to the contents thereof which loss or damage is covered by valid and
collectable fire and extended coverage insurance policies or other property
damage policies to the extent that such loss or damage is recovered under such
policies.

                                 SECTION SEVEN
                        COMPLIANCE WITH UNDERLYING LEASE

     Subtenant shall not cause or allow any undue waste or other deterioration
on the Sublease Premises or Premises and shall comply with all applicable laws
and ordinances respecting the use and occupancy of the Sublease Premises or
Premises relating to matters not covered elsewhere in this Sublease.

     This Sublease and Subtenant's rights under this Sublease shall at all times
be subject and subordinate to the Underlying Lease, and Subtenant shall
otherwise abide by all of the terms of the Underlying Lease, with respect to the
Sublease Premises and its use of the Premises.  The Subtenant covenants and
agrees to use the Sublease Premises in accordance with the terms and conditions
of the Underlying Lease and further covenants not to do any act which will
result in violation of the terms of the Underlying Lease.

     In furtherance of the foregoing, the parties hereby confirm each to the
other, that it is not practical in this Sublease agreement to enumerate all of
the rights and obligations of the various parties under the Underlying Lease and
specifically to allocate those rights and obligations in this Sublease.
Accordingly, in order to afford to Subtenant the benefits of this Sublease and
of those provisions of the Underlying Lease which, by their nature are intended
to benefit the party in possession of the Premises, and in order to protect
Tenant against a default by Subtenant which might cause a default or event of
default by Sublandlord under the Underlying Lease, the following privileges
shall apply.  Notwithstanding the above, any terms in this Sublease that are
inconsistent with the Underlying Lease shall govern and control the rights and
obligations of and between Tenant and Subtenant.

     Provided Subtenant shall timely pay all rent when and as due under this
Sublease, Tenant shall pay when and as due all base rent, additional rent and
other charges payable by Tenant to Landlord under the Underlying Lease, Tenant
shall perform its covenants and obligations under the Underlying Lease which do
not require for their performance possession of the Sublease Premises and which
are not otherwise to be performed hereunder by Subtenant on behalf of Tenant.
For example, but not in limitation, Tenant shall at all times keep in full force
and effect all insurance required of Tenant as tenant under the Underlying
Lease.  Tenant hereby grants to Subtenant the right to receive all of the
services and benefits with respect to the Sublease Premises which are provided
by Landlord under the Underlying Lease.  Tenant shall have no duty to perform
any obligations of Landlord which are, by their nature, the obligation of an
owner or manager of real property.  Tenant shall have no responsibility for or
be liable to Subtenant for any default, failure or delay on the part of Landlord
in the performance or observance by Landlord of any of its obligations under the
Underlying Lease, nor shall such default by Landlord affect his Sublease or
waive or defer the performance of any of Subtenant's obligations hereunder
except to the extent that such default by Landlord excuses performance by
Tenant, under the Underlying Lease.  Subtenant's sole recourse for a violation
of the Underlying Lease by Tenant, except for payment permitted under Section 3,
is termination of this Sublease

                                       5
<PAGE>

in the event the Underlying Lease is terminated or the use of the Sublease
Premises is interrupted by the Landlord as a result thereof.

     As they apply to the Sublease Premises or Subtenant's use, Subtenant shall
perform all affirmative covenants and shall refrain from performing any act
which is prohibited by the negative covenants of the Underlying Lease, where the
obligation to perform or refrain from performing is by its nature imposed upon
the party in possession of the Sublease Premises.  If practicable, Subtenant
shall perform affirmative covenants which are also covenants of Tenant under the
Underlying Lease at least three (3) days prior to the date when Tenant's
performance is required under the Underlying Lease.  Notwithstanding anything to
the contrary contained in this Sublease, but without limitation of Subtenant's
obligation to pay rent hereunder, Subtenant shall have no obligation to pay
Total Rent due from Tenant under the Underlying Lease.  Tenant shall have the
right to enter the Sublease Premises to cure any default by Subtenant under this
Section.

     Without limitation of the foregoing, Subtenant shall not violate the
Underlying Lease, nor shall Subtenant knowingly permit any act or omission to
occur upon the Sublease Premises which violates the Prime Lease.
Notwithstanding anything to the contrary contained herein, Subtenant and Tenant
agree to indemnify the other for and to hold the other harmless from all costs
and expenses of any nature whatsoever (including without limitation reasonable
attorneys' fees) related to any violation of this Section 7, unless the same
arises due to the acts or omissions of the other.

     Subtenant acknowledges that any termination of the Underlying Lease shall
extinguish this Sublease.  Landlord's consent to this Sublease (i) shall not
make Landlord a party to this Sublease, (ii) shall not create any privity of
contract between Landlord and Subtenant or other contractual liability or duty
on the part of the Landlord to the Subtenant, (iii) shall not constitute
Landlord's consent or waiver of consent to any subsequent sublease or sub-
sublease, and (iv) shall not in any manner increase, decrease or otherwise
affect the rights and obligations of Landlord and Tenant under the Underlying
Lease, in respect to the Sublease Premises.  Any term of this Sublease that in
any way conflict with or alters the provisions of the Underlying Lease shall be
of no effect as to Landlord, and Landlord shall not assume any obligations as
landlord under the Sublease, and Subtenant shall not acquire any rights under
the Sublease directly assertable against Landlord under the Underlying Lease.

     Subtenant hereby expressly agrees to be bound by the following provisions
of the Agreement:

          (a)  Paragraph 4(c) -- That, in the interest of public health, the use
               --------------
               of lighted tobacco products will not be permitted in buildings
               upon the leased premises.

          (b)  Paragraph 4(g) -- Johnson assures that it will undertake an
               --------------
               Affirmative Action program as required by CFR Part 152, Sub-part
               E, to insure that no person shall on the grounds of race, creed,
               color, national origin, handicap or sex be excluded from
               participating in any employment activities on the leased premises
               covered in 14 CFR, Part 152, Sub-part E.  Johnson assures that no
               person shall be excluded on these grounds from participating in,
               or

                                       6
<PAGE>

               receiving the services or benefits of, any program or activity on
               the leased premises covered by this sub-part. Johnson assures
               that it will require that its covered sub-organizations provide
               assurance that they similarly will undertake Affirmative Action
               programs, and that they will require assurance from their sub-
               organizations, as required by 14 CFR, part 152, Sub-part E, to
               the same effect for their respective operations on the leased
               premises.

                                  SECTION EIGHT
                                     REPAIRS

     Subject to the obligations of Landlord, if any, in the Underlying Lease,
Tenant, unless herein specified to the contrary, shall maintain the Sublease
Premises in good repair and tenantable condition to the extent required by the
Underlying Lease during the continuance of this Sublease, except in case of
damage arising from wilful or negligent acts or omissions of Subtenant or the
agents, servants, employees, invitees or visitors of Subtenant which shall be
repaired by Subtenant.

                                  SECTION NINE
                     ALTERATIONS, ADDITIONS OR IMPROVEMENTS

     Subtenant shall not make any alterations, additions, or improvements on or
to the Premises or Sublease Premises without first obtaining the written consent
of Tenant and Landlord.  At the request of Tenant or Landlord, which request
must be received by Subtenant at least ten (10) days prior to the expiration or
five (5) days prior to any earlier termination of this Sublease, Subtenant shall
remove at the end of the term, all personal property, all alterations, additions
or improvements made by Subtenant.  To the extent not so requested, all
alterations, additions, and improvements shall remain on and be surrendered with
the Premises as a part thereof at the termination of this Sublease without
disturbance, molestation or injury.

                                  SECTION TEN
                                     LIENS

     Subtenant shall keep the Sublease Premises free and clear of all liens
arising out of any work performed, materials furnished, or obligations incurred
by Subtenant.

                                 SECTION ELEVEN
                        SALES, ASSIGNMENTS AND SUBLEASES

     Subtenant shall not assign this Sublease, or sublet or otherwise encumber
the Sublease Premises, or any part thereof or interest therein.

                                 SECTION TWELVE
                                QUIET ENJOYMENT

     If Subtenant performs the terms of this Sublease, Tenant will warrant and
defend Subtenant in the enjoyment and peaceful possession of, and shall not
disturb Subtenant's tenancy

                                       7
<PAGE>

in the Sublease Premises during the term hereof without any interruption by
Tenant or any person rightfully claiming under Tenant.

                                SECTION THIRTEEN
                                  CONDEMNATION

     If the Sublease Premises or any parts thereof are appropriated or taken for
any public use by virtue of eminent domain or condemnation proceedings, or if by
reason of law, ordinance, or by court decree, whether by consent or otherwise,
the use of the Sublease Premises by Subtenant for any of the specific purposes
referred to herein shall be prohibited, Tenant or Subtenant shall have the right
to terminate this Sublease as of the date of surrender of possession of the
Premises or a portion thereof to the condemning authority on at least ten (10)
days written notice to the other party, and rental shall be paid only to the
time when Subtenant surrenders possession of the Sublease Premises.  This
Sublease shall terminate if the Underlying Lease is terminated.  Any rental paid
in advance beyond the time that the Property has been taken from Subtenant and
this Sublease terminates shall be returned promptly by Tenant to Subtenant on
demand.  Subtenant waives any right to recover from the condemning authority for
any damage that may be suffered by Subtenant by reason of any condemnation.

                                SECTION FOURTEEN
                     TENANT'S REPRESENTATIONS AND WARRANTIES

terms, covenants or provisions of the Underlying Lease.

     (2) The Underlying Lease has not been altered, amended or modified except
