I.   Financing shall be carried out using the sale and lease back procedure
     (purchase price DM [***] net). The contract shall be focused on partial
     amortization:

     The customer hereby confirms that he is the owner of the products and that
     third-party rights do not exist.  Title shall pass to PMG upon payment of
                           ---

                          ---

PHILIPS MIETSYSTEM GMBH

LEASING CONTRACT NO.:  95 02219 097



LEASE TERMS

I.  SUBJECT MATTER OF CONTRACT: 1.  Pursuant to this contract, PMG shall permit
the customer to engage in paid use of the products listed on the front page.

2.  The customer is aware that PMG acquires the products specifically for the
individual contract in order to make them available for use by the customer for
the term of the contract in exchange for payment of monthly compensation.

II.  DELIVERY:  1.  The delivery of the operationally ready products shall be
defined in a delivery protocol, of which the customer shall receive a copy.

2.  The delivery period shall be extended in a reasonable manner, if PMG is
prevented from performing this contract in a timely manner due to strike, lock-
out, Act of God or delivery disruptions with the manufacturer, supplier or
subcontractor.  The customer may terminate the contract if PMG is in default and
does not perform within a reasonable grace period.  Deadline imposition and
notice of termination must be in writing.  If PMG is in default with respect to
a portion of the delivery, and the customer is able to use the other products
independently, the customer shall be solely entitled to a corresponding partial
termination of the contract.

3.  If it is impossible for PMG to perform the contract in whole or in part due
to the reasons stated in section 2, PMG shall be

 
released from its duty to deliver and the customer shall be released from its
duty to pay.

4.   PMG shall be entitled to make partial deliveries and render partial
services.

5.   As long as the customer is in default with respect to payment of the
monthly compensation or payment on a delivery or service which PMG provided
pursuant to this contract, PMG shall be entitled to withhold deliveries or
services without incurring an obligation to make compensation for any damages
which arise.

III. CONTRACT TERM:  1.  The use relationship shall begin on the date of
delivery of the operationally ready products.  If PMG makes partial deliveries
which can be used by the customer independent of the still outstanding
deliveries, and pro rata compensation can be seen from the contract or delivery
protocol, the use period shall begin separately for each sub-product upon
operationally ready delivery.

2.   The contract is concluded for an indefinite term.

3.   The customer may terminate the use relationship or the individual sub-use
relationships upon notice of 6 months no earlier than the end of the imputed
term.  The imputed term (in months) shall begin at the beginning of contractual
payment.

4.   PMG hereby irrevocably offers the customer the opportunity to rescind the
contract on a mutually agreeable basis in exchange for a compensation payment.
The customer may accept this offer upon declaration notice of 6 months effective
no earlier than the end of the month following the respective beginning of
contractual payment which corresponds to half of the stipulated imputed term--
rounded up to full months.  This offer shall only apply if 40% of the ordinary
operational useful life has been fulfilled.

A settlement payment shall be due upon acceptance of the contract.  It shall be
calculated based on the total of the compensation still outstanding through the
expiration of the imputed term.  Upon acceptance of this offer, the remaining
sum shall accrue interest at the prevailing Bundesbank discount rate at the time
of premature end of the contract.  The sum, plus the prevailing value-added tax,
shall be due without deduction on the date of the premature end of the
contractual relationship.  (In addition, the costs of return pursuant to section
XV shall be due).

In the event of the sale of the products returned to PMG within

 
90 days, 90% of the net sales proceeds--but not more than the amount of the
compensation payment therefor--shall be credited to the customer.

IV. PAYMENT:  1. The customer shall pay compensation on a monthly basis in
advance starting from the first day of the month following delivery of the
operationally ready products.  The compensation shall not include any fees
payable to the Deutsche Bundespost or other agency.

2.  If the customer defaults on a payment, PMG shall be entitled to charge
interest in the amount of 3% above the respective discount rate of the Deutsche
Bundesbank.

3.  The customer may only assert a right of retention if said right is based on
claims arising from this leasing contract.  He shall be entitled to an offset
against the claims of PMG if PMG has acknowledged the customer's counter claim
or if said counter claim has been established by final judicial determination.


V.  CHANGE IN COMPENSATION:  1.  The monthly compensation may be adjusted
accordingly if the delivery of products pursuant to the agreement takes place
more than 4 months following the conclusion of the contract and the sales prices
for the products charged by the suppliers changes during this period.

2.  If the cost factors which influence the compensation change following
conclusion of the contract, or if the taxes payable in connection with this
contract are changed, revoked or reintroduced, the monthly compensation may be
adjusted in accordance with the changed circumstances.

3.  The adjustment shall be made in writing and shall include communication of
the amount and the point in time from which the change of compensation shall
apply.

4.  If, as a result of the adjustment pursuant to section 2--in relation to the
overall leasing period to date--the compensation increases by more than an
annual average of 5%, the customer shall be entitled to terminate the contract
within a period of 4 weeks following receipt of the written notice of
modification; said termination shall be effective on the date on which the new
compensation would become effective in the absence of termination.  Said
termination right on the part of the customer

 
shall not exist if new or modified taxes were the reason for the increase of
compensation.
