interest shall be payable in accordance with the following provisions:

                                  3.1      Installments of Principal and
                 Interest.  Commencing on the Initial Payment Date and then on
                 each Quarterly Payment Date thereafter, Borrower shall pay to
                 Lender a combined installment of principal and interest in the
                 amount of the Quarterly Payment which shall be applied first
                 to accrued and unpaid interest and then to principal;
                 provided, however, the amount of each Quarterly Payment to be
                 applied to principal shall be not less than $200,000, and
                 Borrower shall be required to pay the shortfall, if any, on

                                  3.2      Payment at Maturity.  The entire
                 unpaid principal balance of this Note and all accrued but
                 unpaid interest under this Note shall be due and payable on
                 the Maturity Date.

                 4.       Calculation of Interest; Application of Payments.
Interest shall be calculated on the basis of a 360-day year and actual days
elapsed.  All payments under this Note shall be credited first to costs and
expenses, then to accrued interest then due and thereafter to unpaid principal.

                 5.       Prepayment.  This Note may be prepaid in whole or in
part at any time, subject to the payment of any amounts which may be owing
pursuant to Section 2.5 of the Loan Agreement and this Section.  Borrower
agrees to indemnify and hold Bank free from any loss or reasonable expense
(including, without limitation, any loss or reasonable expense incurred by
reason of the liquidation or redeployment of deposits or other funds acquired
by Bank to fund or maintain the Loan) which Bank may incur as a result of (a) a
default by Borrower in payment when due of the principal amount or
   3
interest in the Loan, or (b) any prepayment (whether mandatory, upon demand by
Bank or otherwise) prior to the end of any Quarterly Period.  At the election
of Bank such losses shall be conclusively deemed to consist of any amount equal
to the sum of:

                 i)       The interest that would have been received from
                 Borrower on the amounts to be redeployed during the Quarterly
                 Period (or remaining portion thereof) in question had Borrower
                 not failed to repay or prepaid such funds, less

                 ii)      the return which Bank could have obtained at a place
                 such funds are on deposit in the interbank dollar market
                 selected by Bank in its sole discretion on the date of such
                 failure to repay or prepayment or and such funds had remained
                 on deposit until the end of the relevant Quarterly Period.

Borrower acknowledges that prepayment of such amount will result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full extent of such costs, expenses and/or
liabilities.  Borrower, therefore, agrees to pay the above-described prepayment
fee and agrees that said amount represents a reasonable estimate of the
prepayment costs, expenses and/or liabilities of Bank.  Concurrently with any
prepayment of principal, Borrower shall notify Lender in writing that Borrower
is making a prepayment in an amount specified in such written notice.

                 6.       Acceleration Upon Certain Transfers.  The Mortgage
and the Loan Agreement contains provisions allowing Lender to accelerate the
maturity of this Note, among other circumstances, upon sale, transfer or
further encumbrance of the aircraft described in the Mortgage.

                 7.       Default.  If any payment under this Note (whether of
principal or interest or both) is not paid within three (3) days after the date
on which the payment is due (irrespective of whether Borrower has received any
notice of such nonpayment) or if Borrower fails to perform fully and when due
any other covenant or obligation of Borrower under this Note, or if an "Event
of Default" shall have occurred under the Mortgage or the Loan Agreement,
Borrower shall be in default hereunder and Lender may elect, without any
further notice or demand to Borrower, to declare all principal and accrued but
unpaid interest under this Note immediately due and payable.  Any failure of
Lender to make such election following a default or defaults shall not
constitute a waiver of Lender's rights to make the election in the event of any
subsequent default.  Notwithstanding any provisions in this Note to the
contrary, any principal, accrued interest, late payment charges and other
amounts which are payable under this Note, the Mortgage, the Loan Agreement or
any other instrument, agreement or document executed by Borrower in connection
with the Loan and which remain unpaid on the Maturity Date or any acceleration
of this Note shall thereafter bear interest, at the Default Rate.  Borrower
expressly acknowledges and agrees that the accrual of interest at the Default
Rate is reasonable under the circumstances existing on the date of this





                                       3
   4
Note, that it would be extremely difficult and impractical to fix Lender's
actual damages arising out of any failure to pay the outstanding indebtedness
of this Note upon the Maturity Date or upon any acceleration of this Note and
that interest accrued at the Default Rate shall be presumed to be the actual
amount of such damages incurred by Lender.  Upon Borrower's default under this
Note, Lender, at its option, shall have the right to apply all payments made by
Borrower in connection with the Loan to principal, accrued interest, late
payment charges and other amounts which are payable under this Note, the
Mortgage, the Loan Agreement, or any other instrument, agreement or document
executed by Borrower in connection with the Loan in such order and amounts as
Lender may determine in its sole and absolute discretion.

                 8.       Late Payment Charge.  If any payment under this Note
(whether of principal or interest or both and including the payment due on the
Maturity Date or upon any acceleration of this Note) is not paid within three
(3) days after the date on which the payment is due, Borrower shall pay to
Lender, in addition to the delinquent payment and without any requirement of
notice or demand by Lender, a late payment charge equal to the Late Charge.
Borrower expressly acknowledges and agrees that the foregoing late payment
charge provision is reasonable under the circumstances existing on the date of
this Note, that it would be extremely difficult and impractical to fix Lender's
actual damages arising out of any late payment and that the foregoing late
payment charge shall be presumed to be the actual amount of such damages
incurred by Lender.  No provision in this Note (including, without limitation,
the provisions for a late payment charge) shall be construed as in any way
excusing Borrower from its obligation to make each payment under this Note
promptly when due.

                 9.       Costs of Collection.  Borrower and all endorsers
jointly and severally promise to pay (a) all costs and expenses of collection,
including, without limitation, attorneys' fees, in the event this Note or any
portion of this Note is placed in the hands of attorneys for collection and
such collection is effected without suit;  (b) attorneys' fees, as determined
by the court or by arbitration, and all other costs, expenses and fees incurred
by Lender in the event suit or arbitration is instituted to collect this Note
or any portion of this Note; and (c) all costs and expenses, including, without
limitation, attorneys' fees incurred by Lender in connection with any
bankruptcy, insolvency or reorganization proceeding or receivership involving
Borrower or any affiliate of Borrower, including, without limitation,
attorneys' fees incurred in making any appearances in any such proceeding or in
seeking relief from any stay or injunction issued in or arising out of any such
proceeding.

                 10.      Arbitration.  Borrower acknowledges and agrees to the
arbitration provisions attached to the Loan Agreement as Exhibit "A", the terms
of which are incorporated herein.

                 11.      Offsets.  No indebtedness evidenced by this Note
shall be deemed to have been offset or shall be offset or compensated by all or
part of any claim, cause of action, counterclaim or cross-claim, whether
liquidated or unliquidated, which





                                       4
   5
Borrower now or hereafter may have or claim to have against Lender.
Furthermore, in respect to the present indebtedness of, or any future
indebtedness incurred by, Borrower to Lender, Borrower waives, to the fullest
extent permitted by law, the benefits of any applicable law, regulation or
procedure which substantially provides that, where cross-demands for money have
existed between persons at any point in time when neither demand was barred by
the applicable statute of limitations, and an action is thereafter commenced by
one such person, the other may assert in his answer the defense of payment in
that the two demands are compensated so far as they equal each other,
notwithstanding that an independent action asserting the claim would at the
time of filing the answer be barred by the applicable statute of limitations.

                 12.      Certain Waivers.  Borrower and endorsers jointly and
severally waive diligence, grace, demand, presentment for payment, exhibitions
of this Note, protest, notice of protest, notice of dishonor, notice of demand,
notice of nonpayment and any and all exemption rights against the indebtedness
evidenced by his Note; and agree to any and all extensions or renewals from
time to time without notice and to any partial payments of this Note made
before or after maturity and that no such extension, renewal or partial payment
shall release any one or all of them from the obligations of payment of this
Note or any installment of this Note; and consent to offsets of any sums owned
to any one or all of them by Lender at any time.

                 13.      Loss, Theft, Destruction or Mutilation of Note.  In
the event of the loss, theft or destruction of this Note, upon Borrower's
receipt of a reasonably satisfactory indemnification agreement executed in
favor of Borrower by the party who held this Note immediately prior to its
loss, theft or destruction, or in the event of the mutilation of this Note,
upon Lender's surrender to Borrower of the mutilated Note, Borrower shall
execute and deliver to such party or Lender, as the case may be, a new
promissory note in form and content identical to this Note in lieu of the lost,
stolen, destroyed or mutilated Note.

                 14.      Notices.  The provisions of the Mortgage and the Loan
Agreement concerning the giving and receipt of notices shall apply to any
notice or other communications given under this Note.

                 15.      Obligations Joint and Several.  If Borrower consists
of more than one person or entity, each shall be jointly and severally liable
for the performance of each of the obligations of Borrower to Lender hereunder.

                 16.      Construction of Note.  Captions in this Note are
included solely for convenience and are not to be referred to in construing or
interpreting this Note.  Each reference in this Note to a particular paragraph
is a reference to a paragraph of this Note unless otherwise expressly
indicated.  The terms "include", "includes" and "including" are not used in any
limiting sense, but rather by way of example or illustration.  If any portion
of this Note is declared invalid, illegal or unenforceable by any court of
competent jurisdiction, such portion shall be deemed severed from this Note and
the





                                       5
   6
remaining portions shall continue in full force and effect.  Time is strictly
of the essence of each and every provision of this Note.  This Note shall be
governed by and interpreted and enforced according to the laws of the State of
California.

                 IN WITNESS WHEREOF, Borrower does execute this Note as of the
date first written above.
