      FOR VALUE RECEIVED, TigerAir, Inc., a Texas corporation (the
"Maker"), promises to pay to the order of Aero Services

successors and assigns and any other transferee or successor
then becoming holder of this Note, "Payee"), in lawful money of
the United States of America at the principal office of Payer at
660 Newtown-Yardley Road, Newtown, Pennsylvania  18940, or at
such other place as Payee may from time to time designate by
written notice to Maker, the lesser of Fifty Thousand Dollars
($50,000) or the aggregate unpaid principal amount then
outstanding on the Working Capital Loan (as defined in that
certain Transfer Agreement by and among Maker and Payee of even
date herewith (the "Agreement")), together with all interest,
fees, costs and penalties thereon, as follows:

 1.     Agreement.  This Note is the Working Capital Note issued pursuant to,
and is payable in accordance with, the Agreement.  Any
capitalized term used in this Note but not defined herein shall
have the meaning ascribed to such term in the Agreement.  The
terms, covenants, conditions, provisions, stipulations and
agreements of the Agreement are incorporated herein by
reference, and are hereby made a part of this Note to the same
extent and with the same effect as if they were fully set forth
herein, and Maker hereby covenants to abide by and to comply
with each and every term, covenant, provision, stipulation,
promise, agreement and condition set forth in this Note and in
the Agreement.  The holder of this Note is entitled to the
benefits of the Agreement to which reference is hereby made for
a statement of the terms and conditions under which this Note is
issued and may enforce the agreements of Maker contained therein
and exercise remedies provided for thereby or otherwise
available in respect thereof.

 2.          Interest.  Commencing as of the date hereof and continuing until
repayment in full of all sums due hereunder, the unpaid
principal sum of this Note shall bear interest at the rate of
nine and one-half percent (9.5%) per annum (the "Interest
Rate").  Interest shall accrue daily.  All computations of
interest hereunder shall be made on the basis of a year of 360
days, for the actual number of days occurring in the period for
which such interest is payable (including the first day but
excluding the last day).

3.   Payments and Maturity.  The entire outstanding principal sum under this
Note shall be due and payable on October 7, 1996, unless
accelerated by Payee (the "Maturity Date").  Accrued interest on
the outstanding principal sum of this Note shall be payable
monthly in arrears, and shall be due and payable on the first
(1st) day of each month.  Any amount of principal outstanding
hereunder in excess of the Credit Line Cap (as defined in the
Agreement) shall be immediately due and payable.  All unpaid
principal, accumulated interest and any fees or charges owed to
Payee shall be payable in full on the Maturity Date.

4.       Prepayment.  Maker shall have the right, at any time, to prepay the
outstanding principal amount of this Note, in whole or in part
from time to time (without premium or penalty), provided that
Maker contemporaneously therewith pays Payee all accrued but
unpaid interest together with all other sums then due hereunder
or on account hereof.                                                          
   

5.           Late Charges and Default Interest.  Any payment of principal or
interest not paid within ten (10) business days after the date
on which it is due shall result in a late charge in the amount
of five percent (5%) of the payment so due.  The assessment or
collection of such charge shall not be construed as a waiver by
Payee of any default occasioned by the failure of Maker to make
such payment within ten (10) business days of its due date. 
During the continuance of an Event of Default (as hereinafter
defined), interest shall accrue on the outstanding principal sum
of this Note at the rate of twelve percent (12%) per annum (the
"Default Interest Rate").

6.     Application of Payments.  Each and all of the payments made hereunder
shall be applied first to expenses and costs incurred by Payee
and for which Maker is responsible; second, to any accrued and
unpaid fees; third, to accrued and unpaid interest hereunder;
and, fourth, to the principal balance of this Note.

7.     Advances.  Advances of principal, prepayment and readvances under the
Working Capital Loan may be made from time to time in accordance
with the Agreement, but Payee, in its sole discretion, may
refuse to make advances or readvances hereunder during the
continuance of an Event of Default hereunder. 

8.    Statement of Account.  From time to time, Payee may furnish Maker with
a statement of Maker's account under the Working Capital Loan,
which statement shall be deemed to be correct, accepted by and
binding on Maker, unless Payee receives a written statement of
exceptions from Maker within twenty (20) days after such
statement of account has been furnished to Maker.  

9.     Security.  Payment of this Note is secured in accordance with Section
14 of the Agreement, including the security interests and liens
granted pursuant thereto or otherwise in connection therewith
and any other assignments and conveyances made from time to time
pursuant to the Agreement.

10.          Event of Default.  If Maker (i) fails in any way to perform its
obligations under this Note, the Acquisition Capital Note (as
defined in the Agreement), the Agreement, or any other
instrument, document or agreement executed by Maker pursuant to
or in otherwise in connection with the Agreement, (ii) fails in
any way to observe any covenant or agreement under this Note,
the Acquisition Note, the Agreement, or any other instrument,
document or agreement executed by Maker pursuant to or in
otherwise in connection with the Agreement, or (iii) fails to
make any payment when due under this Note or the Acquisition
Note, which default is not cured within ten (10) days (each of
the foregoing constituting an "Event of Default" hereunder),
then, Payee, at its option and without further notice to Maker,
may declare immediately due and payable the entire unpaid
principal sum due hereunder (with interest to accrue thereafter
at the Default Interest Rate), and all other charges and sums
due by Maker under this Note of the Agreement; and payment
thereof may be enforced and recovered in whole or in part at any
time by one or more of the remedies provided to Payee in the
Agreement, or at law or equity.  In such case Payee may also
recover all costs of suit and other expenses in connection
therewith, together with an attorneys' commission, for
collection, of five percent (5%) of the total amount then due by
Maker to Payee, together with interest on any judgment obtained
by Payee at the Default Interest Rate.  Payee may exercise this
option to accelerate during any default by Maker regardless of
any prior forbearance.

EMPOWER ANY ATTORNEY OF COURT OF RECORD OF PENNSYLVANIA OR ELSEWHERE
TO, ON THE OCCURRENCE OF A DEFAULT UNDER THIS NOTE, APPEAR FOR AND ENTER

and under the Agreement, together with all other remedies

and may be pursued singly, successively or together at the sole

13.        Waiver and Release.  To the extent permitted by law, Maker hereby
waives and releases all errors, defects and imperfections in any
proceedings instituted by Payee under the terms hereof or of the

virtue of any present or future laws exempting any property, or
any part of the proceeds arising from any sale of any property,
from attachment, levy or sale under execution, or providing for
any stay of execution, exemption from civil process, or
extension of time for payment; and maker agrees that any
property that may be levied against pursuant to a judgment
obtained by virtue hereof, on any writ of execution issued
thereon, may be sold on any such writ in whole or in part in any
order desired by Payee.

      Maker and all endorsers, sureties and guarantors, hereby
jointly and severally waive presentment for payment, demand,
notice of demand, notice of non-payment or dishonor, protest and
notice of protest of this Note, and all other notices in connec-
tion with the delivery, acceptance, performance, default or
enforcement of the payment of this Note, and they agree that the
liability of each of them shall be unconditional, without regard
to the liability of any other party, and shall not be affected
in any manner by an indulgence, extension of time, renewal,
waiver or modification granted or consented to by Payee.  Maker
and all endorsers, sureties and guarantors consent to any and
all extensions of time, renewals, waivers, or modifications that
may be granted by Payee with respect to the payment or other

part thereof, with or without substitution, and agree that

parties hereto without notice to them or affecting their
liability hereunder.

sion, to have waived any of its rights or remedies hereunder
unless such waiver is in writing and signed by Payee, and then
only to the extent specifically set forth in the writing.  A
waiver on one event shall not be construed as continuing or as
a bar to or waiver of any right or remedy to a subsequent event.

 14.       Governing Law.  This instrument shall be governed by and construed
according to the laws of the Commonwealth of Pennsylvania,
including its statutes or limitation but without regard to its
rules governing conflict of laws.

of the Federal and State Courts sitting in or for Bucks County,

of reference only and shall not be deemed to define, limit or
describe the scope or intent of this Note.

17.    Partial Invalidity.  In the event that any provision of this Note (or
any part of any provision) is held by a court of competent
jurisdiction to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality, or unenforceability shall
not affect any other provisions (or remaining parts of the
affected provision) of this Note; but this Note shall be con-
strued as if such invalid, illegal, or unenforceable provision
had not been contained herein, but only to the extent it is
invalid, illegal, or unenforceable.

18.     Maximum Rate of Interest.  It is not intended by this Note to charge
interest at a rate in excess of the maximum rate of interest
permitted to be charged to Maker under applicable law, but if,
notwithstanding, interest in excess of the maximum rate shall be
paid under this Note, the excess shall be retained by Payee and
applied to reduce the principal sum outstanding, or returned to
Maker.

the plural, the plural the singular, and the use of any gender
shall be applicable to all genders, and words "Payee" and
