            ADDITIONAL PROVISIONS CONCERNING RIGHTS OF THE PARTIES


APPLICATION OF PAYMENTS:  Any sums received from me may be applied at Lender's
discretion to obligations hereunder or to any other indebtedness owed by me to
Lender despite directions, if any, appearing on the remittance, and to interest
before principal, and if permitted by law to past due interest before
installments.  If any proceeds from the sale of the Goods or insurance are
applied to the debt, I remain liable to make each monthly payment described in
this contract until it is paid in full.  Lender may accept payments marked "paid
in full" or with other restrictive endorsements, without losing any of your
rights under this Agreement.

DEFAULT:  This contract shall be in default (a) if I fail to pay any
installment when due; (b) if I attempt to sell or encumber any interest in the
Goods; (c) if I institute or have instituted against me proceedings under any
bankruptcy or insolvency law; (d) if I make an assignment for the benefit of
creditors; (e) if I fail to pay taxes levied on the Goods; (f) if any
attachment, execution, writ, or other process is levied against any of my
property; (g) if I fail at any time to keep the Goods properly insured as
described below; (h) if I remove the Goods, without prior written notice to
Lender, from the location in which I have agreed to keep them; (i) if I fail to
maintain the Goods in good condition and repair or permit its value to be
impaired; (j) if I permit the Goods to be used in violation of any law,
regulation or policy of insurance; (k) if any representation, warranty or
statement is made to Lender in connection with this agreement which is false in
any material respect when made; (l) if any legal entity such as a partnership,
limited liability company or corporation) that has agreed to pay this agreement
ceases to do business, dissolves, liquidates its assets or terminates or fails
to maintain its legal existence; (m) if I fail to comply with any other
provision of this contract: or (n) if for any reason Lender deems the debt or
security unsafe. In any such event Lender may take possession of any Goods in
which Lender has a Security Interest and exercise any other remedies provided by
law. In such event I agree, upon demand, to assemble the Goods at a location
designated by Lender, and Lender may immediately and without notice declare the
entire balance of this contract due and payable. In addition, to the extent
permitted by law, Lender may collect all reasonable expenses, including
attorney's fees, incurred in realizing on the security interest granted
hereunder, or otherwise enforcing the terms of this contract. If I reside in
Texas, I agree that any remaining amounts due under this contract after any
default by me shall be payable to Lender or its order at Dallas, in Dallas
County, Texas.

If Lender takes possession of the Goods after I default, it shall be
commercially reasonable for Lender to sell; (i) the Goods at a private sale;
(ii) at wholesale to a dealer in used goods of like kind; or (iii) at retail to
a purchaser directly or through a dealer in such used goods.  The enumeration of
the foregoing methods of disposition are without limitation to the Lender's
right to dispose of the Goods by any other manner or method (whether by sale,
lease, or otherwise) in a commercially reasonable manner.  Lender also has the
right to take possession of the Goods or render the Goods unusable.  Upon
default, I grant Lender permission to cancel any insurance on the Goods and if
allowed by law, to apply any premium refunds to my debt to Lender with any
excess returned to me.  Waiver of any breach or default shall not constitute a
waiver of any other or subsequent breach or default.

RISK OF LOSS AND OTHER AGREEMENTS.  I hold the Goods at my risk and expense with
no abatement in any obligation on account of loss or damage.  I will settle
all claims of any kind against the seller of the Goods directly with the seller
and I will not use any such claim as a defense, setoff or counterclaim against
any effort by Lender to enforce this Contract.  I authorize Lender to file (or
to execute on my behalf and file) a financing statement (or statements) in order
to perfect the security interest granted herein, indicating the type of items
described herein or describing such items.  Each person who signs this Agreement
agrees that any carbon signature, facsimile signature or electronic signature
shall constitute an original signature within the meaning of applicable law, for
all purposes, including the filing of financing statements.  Lender may correct
patent or clerical errors in the Agreement, or any purchase order or financing
statement executed in connection with the transactions contemplated in this
Agreement.  Any provision of this Agreement prohibited by law shall be
ineffective and deemed deleted to the extent of such prohibition and shall not
invalidate any other provision hereof.

INSURANCE:  Except to the extent this Agreement is for service work, I will at
all times keep the Goods insured against all risk of loss, damage or destruction
for greater or their full insurable value or the then outstanding amount of this
Loan.  Lender must be listed as a loss payee.  I may choose the person through
whom I obtain the insurance but the insurance must be acceptable to Lender.
Such insurance will provide that it may not be canceled by me without Lender's
consent and may not be canceled by the insurance company without at least ten
(10) days written notice to Lender.  I will provide Lender with evidence of the
paid-up insurance on the Goods within fifteen (15) days of the date of this
contract and at least thirty (30) days before the renewal date.  If I fail to
provide evidence of the insurance within the time periods specified in the
preceding sentence, then I will reimburse Lender for the cost of any insurance
Lender purchased until the date such evidence is provided by me.  If I fail to
keep the Goods properly insured, Lender may, but is under no obligation to, buy
insurance to protect the Goods and add the cost to my debt to Lender, and I
promise to pay additional cost upon Lender's demand.  To the fullest extent
permitted by law, I will pay Lender a reasonable administrative fee for
obtaining and canceling such insurance.

I may meet this insurance requirement by having Lender purchase such insurance.
Inclusion of any amount of Physical Damage Insurance in the Insurance Disclosure
box on the front of this contract will be election to do this, but such
insurance will only be purchased if Lender accepts this Agreement.  Such
insurance will cover only the fair market value of the Goods at the time of the
loss.  If the term of such insurance is less than the term of this Agreement, I
will, upon termination of such insurance, purchase insurance to fulfill my
obligation to insure hereunder.
