1.   SCOPE OF AGREEMENT; TERM.

(a)  SCOPE OF AGREEMENT. This Agreement sets forth the terms and conditions
governing the purchase and sale of Items, the relationship between Applied and
Supplier, and compliance with Applied's business processes and is intended to
supplant any and all previous agreements, including the "Manufacturing
Agreement" between the parties dated 20 February 1997 and "Addendum" dated 20
March 2000. Applied's current business processes and requirements for certain
matters covered by this Agreement, including packaging, delivery, shipment,
crating and repair of Items, are set forth in the Attachments. Applied
Materials, Inc. and its subsidiaries shall be entitled to purchase and use Items
from Supplier under this Agreement, and shall have all of the rights and
obligations of "Applied" under this Agreement. As to any purchase of Items under
this Agreement by Applied Materials, Inc., all obligations under this Agreement
are the sole obligations of Applied Materials, Inc. As to any purchase of Items
under this Agreement by a subsidiary of Applied, all obligations under this
Agreement are the sole obligations of such subsidiary. This Agreement shall not
apply to Applied's purchase, and Supplier's sale, of any goods or services
pursuant to (i) a purchase order or other agreement which expressly identifies
this Global Supply Agreement and states that the terms and conditions of the
purchase order or other agreement, rather than this Agreement, shall govern the
transaction; or (ii) a joint development or license agreement, except to the
extent expressly provided therein.

(b) TERM. This Agreement shall commence on the Effective Date and, unless
extended as set forth in this Section 2 or terminated as set forth in Section
21, shall expire on 31 October 2004 (the "Term"). At any time prior to
expiration of the Term, Applied may, at its sole option, extend the Term for an
additional period not to exceed six (6) months by delivering written notice to
Supplier of such extension. The Parties acknowledge that after the Term they may
desire to renew this Agreement or enter into a similar volume supply agreement.
If Supplier decides during the Term that it does not wish to enter into such
renewal or volume supply agreement, Supplier shall provide notice thereof to
Applied at least six (6) months prior to the expiration of the Term.

(c)  UPDATING BUSINESS PROCESSES. Applied regularly undertakes to refine and
improve its business processes. In that regard, Applied shall have the right to
amend any Attachment, other than Attachment 1 and Attachment 7, by posting the
amended Attachment on the Applied Web Site, and by giving notice thereof to
Supplier in writing or in the form of a notification appearing on the Applied
Web Site, or by other electronic means. Supplier agrees to regularly access the
Applied Web Site to review any amended Attachments. If Supplier fails to object
to an amendment to an Attachment within thirty (30) days after the date on which
the amended Attachment is posted on the Applied Web Site, then such amended
Attachment shall be deemed to be accepted by Supplier as an Attachment to this
Agreement, effective as of the posting date. All modifications to Attachment 1
and Attachment 7 shall be upon the mutual written agreement of the Parties.

3.   ORDERS.

(a)  ORDERS. All orders for Items shall be in the form of an Authorized Demand
Signal. An Authorized Demand Signal shall (i) identify the Item(s) requested;
(ii) state the quantity, date, time and place of delivery, and price of the
Item(s) requested (unless previously specified in Attachment 1, which shall
control); and (iii) specify if it is for a Spares Down Order (as defined in this
Agreement). Supplier shall accept communications of Authorized Demand Signals in
the format designated by Applied.

(b)  ACCEPTANCE/REJECTION OF ORDERS. Supplier shall promptly communicate its
acceptance or rejection of an Authorized Demand Signal. Supplier shall not,
however, reject an Authorized Demand Signal for

                                        2
<Page>

Items set forth on Attachment 1 so long as the Authorized Demand Signal conforms
to the terms and conditions of this Agreement. Any notice of rejection shall
state the specific grounds for such rejection. Certain Authorized Demand Signals
shall be deemed to be accepted as follows:

     (i) An Authorized Demand Signal that is for a "Spares Down Order" will be
deemed accepted by Supplier upon the expiration of one (1) business hour after
its receipt by Supplier unless Supplier objects by electronic or telephonic
notice within said one (1) business hour period (any telephonic notice of
rejection shall be followed by the delivery of written or electronic notice to
Applied within one (1) business day of delivery of the rejected Authorized
Demand Signal (Supplier business hours are 8:00 am to 5:00 pm Eastern Time)

     (ii) An Authorized Demand Signal sent via EDI or other electronic
transmission will be deemed accepted by Supplier upon the expiration of four (4)
hours after the time it is issued, unless Supplier objects by electronic notice
within said four (4) hour period; and

     (iii) An Authorized Demand Signal that is an Applied purchase order
(whether in hard copy or electronic form) shall be accepted upon the terms
specified within such order.

In all events, any objection by Supplier to the terms of an Authorized Demand
Signal shall be deemed waived upon Supplier's delivery of Items.

(c)  ORDER ADJUSTMENTS. Supplier acknowledges that, due to the highly cyclical
nature of the semiconductor equipment industry and other factors, Applied may be
required to modify Authorized Demand Signals from time to time. Applied may
increase the quantity of Items in any Authorized Demand Signal at any time prior
to the scheduled delivery date and, provided such increase falls within the
Quantity Flexibility Matrix set forth below, (i) Supplier will deliver such
increased quantity with no additional charges including accelerated delivery,
expedite fees or the like, and (ii) such increase will not affect the delivery
schedule of Items previously ordered.

</Table>

If Applied requires an increase in the quantity of Items in any Authorized
Demand Signal and such increase does not fall within the Quantity Flexibility
Matrix set forth above, then, if feasible and as mutually agreed upon by the
Parties, Supplier will provide such increased Items in accordance with the
modified Authorized Demand Signal and Applied shall pay costs resulting there
from, provided such costs are (i) reasonable; (ii) authorized by Applied in
writing in advance of delivery; and (iii) identified separately from the unit
price on Supplier's invoice to Applied.

(d)  REDUCTION OR CANCELLATION OF AN AUTHORIZED DEMAND SIGNAL. If Applied
requires a reduction in the quantity of Items in any Authorized Demand Signal,
or cancels any Authorized Demand Signal, the Parties' respective rights and
obligations shall be: (i) as specified in Section 16 if the Item set forth in
such Authorized Demand Signal is a VMI Item (as defined in Section 16); or (ii)
in Section 21(b) if the Item set forth in such Authorized Demand Signal is not a
VMI Item.

(e)  PURCHASES BY AUTHORIZED THIRD PARTY. Certain Items may be (i) incorporated
into subassemblies or other products made for Applied by a third party; or (ii)
otherwise processed by a third party. In such

                                        3

event, Applied may designate the third party as authorized to purchase such
Item(s) from Supplier and, upon Supplier's receipt of notice thereof, Supplier
shall enter into an agreement with such third party to sell such Item(s) to such
third party on terms (including pricing) consistent with and no less favorable
than the terms set forth in this Agreement.

(f)  NO VOLUME COMMITMENT. Applied does not commit to purchase a specific volume
of any Item from Supplier except as specified in an Authorized Demand Signal
and, subject to Supplier's IP Rights (as defined in section 11(b)), Applied may
manufacture or buy goods and/or services from third parties that are identical
or similar to the Items.

4.   PRICING.

(a)  CONTRACT PRICE. "Contract Price" means the domestic and/or export price in
U.S. Dollars for an Item as set forth on Attachment 1; provided, that if a price
for an Item is not specified on Attachment 1, then the Contract Price shall be
the price set forth in an Authorized Demand Signal that is accepted by Supplier
in accordance with this Agreement. The Contract Price for each Item shall remain
in effect throughout the Term, except for any price reductions or other changes
mutually agreed to by the Parties in writing.

(b)  PRICING COMPONENTS. The Contract Price, and any quotations for Items, shall
include all finishing, testing, inspecting and packaging fees, applicable
royalties and all applicable taxes (excluding sales, use and similar taxes). Any
quotations for Items shall include all costs relating to warranties and such
costs shall be separately identified and itemized. Any quotations for Items
shall not include any amounts relating to (i) initial set-up charges; (ii) costs
for special dies, tools, patterns or test fixtures; and (iii) non-recurring
engineering fees amortized into the per unit price, unless separately identified
and itemized. Quotations for prototypes shall reflect the total value of
Applied's business with Supplier. In this regard, Supplier shall consider
providing a specific number of prototype Items free of charge and/or pricing
prototypes at or near volume pricing.

(c)  TRANSPORTATION COSTS. For Items to be delivered to a destination within the
country of origin, pricing in a quotation or as set forth in Attachment 1 shall
not include any transportation costs other than insurance expense, which shall
be separately identified and itemized. For Items to be delivered outside the
country of origin, all costs for shipping, import/export fees, customs,
insurance and other transportation expenses, for which reimbursement to Supplier
is applicable, shall be separately identified and itemized in a quotation.

(d)  PRICE REDUCTIONS. Supplier shall implement all committed price reductions
set forth in this Agreement and on Attachment 1. All quantities of Items
purchased by Applied and its subsidiaries purchasing under this Agreement will
be aggregated for purposes of calculating applicable price reductions. Any
change in circumstances (such as an increase in Applied's purchase volume, or a
decline in industry conditions), may result in a review of Agreement terms
and/or negotiated reduction in the Contract Price.

(e)  TAXES. Applied will pay any applicable sales, use or similar tax imposed in
connection with the sale of Items to Applied; provided, that Supplier shall not
charge or collect, and Applied shall have no liability for, taxes on any sale of
Items for which Applied has provided Supplier with an appropriate resale
certificate or other documentation evidencing an exemption from such taxes. For
all sales of Items upon which tax reimbursement to Supplier is applicable,
Supplier shall separately identify and itemize all applicable taxes on invoices
submitted to Applied.

(f)  FAVORED CUSTOMER. Subject to Section 9 of this Agreement regarding
prohibited activities and confidentiality, Supplier warrants and agrees that, if
such sales are permitted, it will not sell to any third

party, goods or services similar or identical to any Items upon terms (including
pricing, discounts, and delivery) which are more favorable than those set forth
in this Agreement. When making the determination as to whether terms are more
favorable, Supplier shall take into account the price of an Item independently
and the cumulative volume of business between Supplier and Applied. If Supplier
offers more favorable terms to any third party, then Supplier will provide
prompt notice to Applied, and if agreed upon by Applied, this Agreement shall be
modified to include the more favorable terms. If, as a result of any such
modification, the pricing of an Item is reduced, Supplier will issue a refund or
credit to Applied, at Applied's option, in an amount equal to the savings
Applied would have realized if Applied had been offered the more favorable term
on the date such term was initially offered to the third party. Notwithstanding
the foregoing, in no event shall Supplier offer or sell Items to Applied at
prices or on terms that would be unlawfully discriminatory under applicable law.

5.   DELIVERY OF ITEMS.

(a)  DELIVERY REQUIREMENTS. Time is of the essence as to the delivery of all
Items ordered under this Agreement. Supplier shall meet the (i) negotiated lead
time; (ii) order adjustment requirements as set forth in Section 3; and (iii)
time, date, location and other delivery requirements for Items, as specified in
Attachment 1 or, if not set forth in Attachment 1, as set forth in the
Authorized Demand Signal for said Items, irrespective of which Applied
organization or division has issued the Authorized Demand Signal. Delivery will
be considered timely only if Items are delivered in the correct quantity, and at
the time, date and location specified in the Authorized Demand Signal. If
necessary for Supplier to meet its delivery requirements, Supplier at its
expense, will use expedited delivery methods to complete and deliver the Items.

(b)  DELIVERY REQUIREMENTS FOR SPARES DOWN ORDERS. Supplier acknowledges that it
may be necessary to provide expedited support and delivery service for the
division of Applied responsible for furnishing spare parts and service to
Applied's customers, referred to as Customer Productivity Solutions ("CPS") or
its successor entity. As to any Authorized Demand Signal identified as a "Spares
Down Order," Supplier shall (i) respond (via telephone or electronically) within
one (1) hour to any Applied inquiry relating to a Spares Down Order; (ii) ship
the Items set forth in the Spares Down Order within four (4) hours following
receipt of a Spares Down Order if such Order is sent to Supplier before 2:00
p.m. Supplier local time; or if the Spares Down Order is sent to Supplier after
2:00 p.m. Supplier local time, then before 12:00 p.m. Supplier local time the
following business day; and (iii) notify (via telephone or electronically)
Applied when the Item set forth in the Spares Down Order leaves the Supplier's
facility. If Supplier cannot meet all of Applied's delivery requirements for
Items ordered, then Supplier shall (A) provide notice to Applied of such event,
and (B) prioritize Items set forth in a Spares Down Order over other Items
ordered via any other Authorized Demand Signal. Supplier shall comply with any
special packaging and labeling requirements as to any Spares Down Order, as set
forth in the Attachments entitled "Unit Packaging Label Specifications"
(Attachment 2) and "Packaging (0250-0098)" (Attachment 3a) and "Marking
(0250-01033)" (Attachment 3b) located on the Applied Web Site.

(c)  REMEDIES. If Supplier fails to deliver any Item at the time and place set
forth in the Authorized Demand Signal, Applied shall have the right, at its sole
option, to (i) require Supplier, at Supplier's expense, to use expedited
delivery methods to complete and deliver the Items; (ii) allocate or redirect
the Supplier's deliveries of Items to certain Applied facilities; (iii) reverse
manufacture Items previously purchased by Applied to obtain component parts and
then debit Supplier the reasonable fair market value for those unused remaining
component parts that Applied returns to Supplier excluding Items that are
proprietary to Supplier as designated in Attachment 1("Proprietary Items"); or
(iv) purchase products comparable to the Item in the open market or from other
suppliers and charge Supplier with any cost differential between the Contract
Price and the price paid in the open market or to other suppliers, which cost
may include premium costs for expedited delivery and administrative costs.

6.   SHIPPING AND RISK OF LOSS.

(a)  SHIPPING AND PACKAGING REQUIREMENTS.

     (i) Supplier will ship all Items in accordance with Attachment 4 entitled
"Transportation Routing Guide" located on the Applied Web Site, including use of
approved carriers as may be applicable given the classification of the shipment
(i.e., domestic or international).

     (ii) Supplier shall comply with any special packaging and labeling
requirements for Items as set forth in the Attachments entitled "Unit Packaging
Label Specifications" (Attachment 2) and "Packaging (0250-0098)" (Attachment 3a)
and "Marking (0250-01033)" (Attachment 3b) located on the Applied Web Site. In
the event such Attachments are not applicable to an Item, the Item shall be
packaged, marked and labeled in accordance with best commercial practices. In
all events, however, Supplier must include a valid packing slip number or
package ID on each package or shipment of Items.

(b)  SHIPMENTS AND INSURANCE.

     (i) US-BASED SHIPMENTS. For Items manufactured in the United States where
the applicable destination point is also in the United States, Applied shall be
responsible for all costs and expenses (other than insurance) to deliver the
Items to the applicable destination point once such Items have been tendered to
the carrier, provided that Supplier complies with Applied's Transportation
Routing Guide then in effect. All delivery costs and expenses for such shipment
shall be specified as "Freight - Third Party Bill" on bills of lading or
shipping receipts, to be paid directly by Applied. Unless specifically approved
by Applied in advance, Applied shall not be responsible for, delivery costs and
expenses (i) in excess of the costs determined under Applied's Transportation
Routing Guide for applicable delivery methods; (ii) payable to carriers not
approved under Applied's Transportation Routing Guide, (iii) incurred as a
result of Supplier's need to use expedited delivery methods, unless such
expedited delivery methods are approved by Applied in advance in writing, or
(iv) incurred in connection with the transportation of Items between Supplier
and a Sub-tier Supplier or any other supplier.

     (ii) OTHER SHIPMENTS. For Items not covered by Section 6(b)(i) above,
Supplier shall be responsible for the initial payment of all delivery costs and
expenses, which have been previously approved by Applied, to deliver the Items
to the applicable destination point. Upon submission to Applied of an itemized
invoice, Applied shall reimburse the supplier all costs for shipping,
import/export fees, customs, additional insurance and other transportation
expenses.

     (iii) INSURANCE AND RISK OF LOSS. In all events, Supplier shall be
responsible to insure such Item during transport up to at least the Contract
Price of such Item. Supplier shall be responsible for the risk of loss to an
Item until delivered to the applicable destination point and accepted by
Applied. In addition, Supplier's responsibility for risk of loss continues with
respect to any Item rejected by Applied, or as to any Item for which acceptance
is revoked, except if such loss is caused by the gross negligence of Applied's
employees acting within the scope of their employment.

7.   ACCEPTANCE AND TITLE TRANSFER.

(a)  ACCEPTANCE AND TITLE TRANSFER. Title to an Item will only transfer to
Applied upon acceptance of an Item. Acceptance shall occur only in the event
that: (i) Applied or its designee has received the Item at the specified
destination point; and (ii) either (1) Applied or its designee has entered the
Item into Applied's internal systems, or (2) a period of twenty-four (24) hours
from the delivery of the Item has elapsed, whichever come first. At any point
prior to acceptance, Applied may reject and return any Item that does not
conform to the applicable Specifications and incur no liability or obligation
related to such

                                        6
<Page>

Item. As to Items that are rejected and returned, Applied may recover and offset
or adjust payments in respect of such Items, including any costs or fees related
to shipping and insuring such Items.

(b)  PAYMENT UPON CONSUMPTION MODEL. "Payment Upon Consumption" means a payment
process by which Supplier would retain title to all Items until such time as
Applied has fully integrated such Items into the products manufactured by
Applied. Upon Applied's request to implement a Payment Upon Consumption process,
Supplier will not unreasonably refuse to do so, and the Parties agree to
negotiate in good faith to enter into an agreement setting forth the terms and
conditions of such process.

8.   PAYMENT.

(a)  PAYMENT TERMS. Payment by Applied for an Item will be made thirty (30) days
from the later of the date of (i) Applied's receipt of an invoice for the Item
consistent with the terms of this Agreement and (ii) Applied's acceptance of the
Item per Section 7(a) above. If payment is made within fifteen (15) days of the
later of either (i) or (ii) above, Applied may deduct two percent (2%) from the
amount due as a prompt payment discount. Applied is authorized by Supplier to
make payments under this Agreement by either check or electronic funds transfer,
and Supplier shall provide Applied with the information necessary for electronic
funds transfer capability.

(b)  INVOICES. Upon mutual agreement, Supplier shall participate in Applied's
Evaluated Receipts Settlement ("ERS") program, whereby Supplier is paid based on
the quantity of Items received and the Contract Price for such Items, without
Supplier providing an invoice. The terms and conditions of the ERS program are
as set forth in Attachment 5 entitled "ERS Program Requirements" located on the
Applied Web Site. If the Parties agree that Supplier will not participate in the
ERS program, then Supplier will remit an Item invoice to Applied no earlier than
when the Item is shipped to Applied and adhere to the requirements for invoices
section of Attachment 5 entitled "Invoicing Requirements for Non-ERS Suppliers"
located on the Applied Web Site.

(c)  EFFECT OF PAYMENT AND RIGHT TO OFFSET. Applied's payment for an Item shall
not preclude revocation of acceptance. All payments shall be subject to
adjustment for errors and shortages.. Applied may at any time set off any amount
owed by Applied to Supplier against any amount owed by Supplier to Applied.

(d)  RECONCILIATION OF PAYMENT DISCREPANCIES. As to any payment discrepancy,
including any claim by Supplier against Applied for payment, nonpayment, damages
or other adjustments as to delivered Items (a "Payment Discrepancy"), Supplier
must, as a condition precedent to any such claim, give notice of its Payment
Discrepancy claim by properly completing and delivering to Applied a Payment
Discrepancy notification for all delivered Items within ninety-six (96) days
from the earliest of any of the following which discloses a Payment Discrepancy:
(i) the issuance of an ERS report under the ERS program; (ii) the date on which
an invoice is returned to Supplier; (iii) the date of partial payment or (iv)
the date of delivery of notice to Supplier of a Payment Discrepancy. The
required Payment Discrepancy form, submission procedures and contact information
are as set forth in Attachment 6 entitled "Supplier Payment Discrepancy Claims
Process located on the Applied Web Site.

9.   CONFIDENTIALITY AND PROHIBITED ACTIVITIES.

(a)  GENERAL. "Confidential Information" means all information obtained by,
disclosed to, or developed by Supplier and that is based on, incorporates,
constitutes or derived from any of the following: (i) samples, schematics,
drawings, designs, Specifications, manuals, Applied Forecasts or other
forecasts, Authorized Demand Signals, customer information and other technical,
business, financial or trade secret information obtained from or through
Applied, including Internal Applied Data; and (ii) all other proprietary,
technical, business, financial or trade secret information obtained by Supplier
from or through Applied, Applied's customers and/or Applied's suppliers during
the term of Applied and

Supplier's business relations, or in connection with the negotiation,
performance or enforcement of the Agreement. Confidential Information does not
include information that (A) includes Supplier IP Rights (B) is or becomes a
matter of public knowledge through no fault or act of Supplier; (C) is
rightfully received by Supplier from a third party not subject to restriction on
disclosure of such information; (D) is independently developed by Supplier
without the use of any Confidential Information; or (E) was rightfully in the
possession of Supplier prior to its disclosure by or on behalf of Applied;
provided, however, that such information shall be Confidential Information to
the extent that (1) such information constitutes specific information, even if
it is embraced by more general information which is a matter of public knowledge
or in the possession of Supplier, or (2) such information is a combination of
individual items of information, even if that combination could be reconstructed
from non-confidential sources if none of the non-confidential sources shows the
whole combination and its principle of operation; and, provided further, that
the sale or unrestricted disclosure of an Item or other article or product made
through a confidential manufacturing process of Applied shall not be deemed to
constitute a public disclosure of the process. Supplier shall be permitted to
disclose Confidential Information to the limited extent required pursuant to a
valid order of a court or authorized government agency, provided Supplier has
given Applied a prior opportunity to defend, protect or limit such disclosure.
Applied grants to Supplier the right to use Confidential Information solely for
the purpose of providing Items to Applied. Supplier will provide Confidential
Information only to those individuals who need to know such Confidential
Information to provide Items to Applied and shall ensure that it is clearly
marked as "Applied Materials Confidential Information." Supplier shall use
reasonable care to protect the confidentiality of Confidential Information, and
in any event, Supplier shall use at least that degree of care that Supplier uses
to protect it own like information.

(b)  PROHIBITED ACTIVITIES. Except as expressly authorized in Section 9(a)
above, Supplier shall not use or disclose any Confidential Information for any
purpose, including: (i) reverse engineering the Items; (ii) developing,
designing, manufacturing, engineering, refurbishing, selling or offering for
sale, any good or service which may be used or sold as a replacement for any
Item or other good used on or with Applied equipment for which Applied provided
Supplier with Applied Confidential Information at any time, including
modifications to any Item; or (iii) assisting any third party in any manner to
perform any such activities. In addition, Supplier shall not make or sell to any
third party any good or service that may be used or sold as a replacement for
any Item or other good used on or with Applied equipment for which Applied
provided Supplier with Confidential Information at any time, including
modifications to Items. Further, Supplier agrees not to disclose to Applied any
information that Supplier or any third party regards as proprietary or
confidential. Applied may use without restriction any and all information
disclosed to it by Supplier except as Applied otherwise agrees in writing under
any nondisclosure agreement ("NDA") between the parties.

(c)  OTHER NDA'S. During the business relationship between Supplier and Applied
one or more NDA's may be, or may have been, entered into. In the event of an
apparent conflict between or among provision(s) of this Agreement and any NDA,
such provisions shall be read in a mutually consistent way, or if no such
reading is reasonably possible, the provision(s) that are most protective of
Confidential Information shall take precedence over conflicting or less
protective provision(s).

(d)  EQUITABLE RELIEF. Supplier agrees that Applied would suffer irreparable
harm for which monetary damages are an inadequate remedy, and that equitable
relief is appropriate, if Supplier were to breach or threaten to breach any
obligations in this Section 9.

(e)  PRESS RELEASES/PUBLICITY NOT AUTHORIZED. Supplier will not issue any press
release, advertising, publicity or public statement or in any way engage in any
other form of public disclosure that indicates Applied's relationship with
Supplier or implies any endorsement by Applied of Supplier or Supplier's
products or services, without the prior written approval of Applied. Nothing
herein, shall preclude

disclosure as required by law, provided Supplier has given Applied prior notice
and an opportunity to contest the necessity of such disclosure.

(f)  DISPOSAL OF CONFIDENTIAL INFORMATION. Upon the termination or expiration of
the Agreement, and otherwise upon the request of Applied, Supplier will promptly
return to Applied all Confidential Information and all documentation that reveal
or are based in any way on Confidential Information, and permanently eliminate
the same from all of its computer and information storage systems. Thereafter,
Supplier shall cease all use of Confidential Information. Supplier may, however,
with Applied's prior written approval, destroy any Applied Confidential
Information or documentation, provided that Supplier certifies to Applied the
destruction of such Confidential Information or documentation reflecting same.
In addition, Supplier agrees it will immediately return to Applied any materials
provided to it to facilitate electronic access to Internal Applied Data,
including any K-zone key, documents, software or other items.

10.    ELECTRONIC ACCESS TO INTERNAL APPLIED DATA.

(a)  GENERAL. If Supplier is granted access to Internal Applied Data then, in
addition to Supplier's obligations under Sections 9 and 11, the terms and
conditions of this Section shall apply. Supplier's access to the Internal
Applied Data is subject to compliance with (i) the terms of use, if any, of the
Applied Web Site or such other database or intranet, as applicable, and (ii) any
technical and security requirements of Applied, including the issuance of
passwords and requirements related to using Applied's Virtual Private Network
and "K-zone" key. Applied may terminate Supplier's right of access or change the
method of access to the Internal Applied Data at any time. In no event shall
Supplier facilitate or enable access to Internal Applied Data by any Sub-tier
Supplier or other third party.

(b)  USE. If Applied grants Supplier access to the Internal Applied Data, then
Supplier shall have the limited right to download, store, display and use
Applied Internal Data for the sole purpose of performing its obligations under
this Agreement in connection with the design, manufacture and sale of Items to
Applied. Supplier may not use the Applied Internal Data in any other way,
commercially or otherwise. Unless otherwise notified by Applied, Supplier may
store copies of Internal Applied Data on Supplier's networks and information
storage systems, provided, such Internal Applied Data is stored either on
hardware that is dedicated solely to Applied, or otherwise separated from other
information of Supplier, so that the Internal Applied Data is not accessible to
individuals except as authorized by this Agreement. If Applied provides Supplier
with any recommendations for establishing an interface or other methods of
accessing the Internal Applied Data, Supplier assumes all risk in implementing
any such recommendation. Supplier acknowledges that the Internal Applied Data
may be made available via a software program, which, for convenience, may
identify Supplier as the "Design Owner" or "Owner" in certain instances, or use
other terms which may appear to be inconsistent with the terms of Section 11
(Intellectual Property Rights). Such inconsistent terms will not apply to nor
affect the terms of Section 11 of this Agreement.

(c)  CONSENT TO MONITORING. Supplier agrees that its access to and use of
Internal Applied Data and all acts in connection with Applied's internal systems
are recorded and may be monitored. Supplier expressly consents to such recording
and monitoring. If such recording or monitoring reveals possible evidence of
criminal activities involving any individual, then Applied may provide such
evidence to the appropriate law enforcement organization and take any other
appropriate action.

11.    INTELLECTUAL PROPERTY RIGHTS.

(a)  "APPLIED'S IP RIGHTS" means all rights, whether registered or unregistered,
arising from or relating to patents, copyrights, trade secrets, trademarks,
service marks, trade names, mask works, moral rights and other proprietary
rights in any jurisdiction in and to (i) all inventions, discoveries, works of
authorship,

know-how, technical information, work product, Confidential Information, and/or
other information obtained by Supplier from Applied, whether directly or
indirectly, in the course of performing work under this Agreement
(built-to-print); and (ii) any improvements, enhancements or modifications to
subsection (i). For all non built-to-print Items the parties shall enter into a
separate written agreement to address applicable ownership and license rights to
technologies jointly developed during the course of this Agreement.

(b)  "SUPPLIER'S IP RIGHTS" means all rights, whether registered or
unregistered, arising from or relating to patents, copyrights, trade secrets,
trade marks, service marks, trade names, mask works, moral rights and other
proprietary rights in any jurisdiction in and to (i) all inventions,
discoveries, works of authorship, know-how, technical information, work product
and/or other information made, conceived or developed by Supplier or Sub-tier
Suppliers; and (ii) any improvements, enhancements or modifications to
subsection (i) provided that subsections (i) and (ii) are made, conceived or
developed independent of Applied's personnel, Applied's IP Rights and work
performed under this Agreement, either prior to or after the Effective Date of
this Agreement.

(c)  OWNERSHIP, ASSIGNMENT AND LICENSE. Applied owns all right, title and
interest in Applied's IP Rights. Supplier owns all right, title and interest in
Supplier IP Rights. Supplier hereby irrevocably transfers and assigns to
Applied, without further compensation, any and all of Supplier's right, title
and interest in and to Applied's IP Rights, and Supplier shall cause its
employees, agents, contractors and Sub-tier Suppliers to also assign and
transfer such rights to Applied. Applied grants to Supplier a non-exclusive,
revocable, royalty-free, limited and non-transferable license to use Applied's
IP Rights solely for the purpose of performing Supplier's obligations under this
Agreement to manufacture and sell to Applied Items under the Agreement. This
license may be revoked by Applied at any time, with or without cause, and shall
expire in any event, if not sooner revoked, on the expiration or termination of
the Agreement. Such license shall not be assigned or transferred in any way, and
shall not succeed to or vest in any successor. Nothing in the Agreement shall be
deemed to grant to Supplier any other license or other right to or under any of
Applied's IP Right for Supplier's own benefit to use in any other way,
commercially or otherwise, or to provide or offer Items or other products or
services to any party other than Applied. Supplier further agrees never to make
any claim in or to Applied's IP Rights licensed to Supplier or to any interest
in or derived from same. Notwithstanding this transfer and assignment,
Supplier's IP Rights shall not be assigned or transferred to Applied under this
Section.

(d)  FURTHER ASSURANCES. At no cost to Applied, Supplier will take, and will
cause its employees, agents, and Sub-tier Suppliers to take, all actions
reasonably requested by Applied, from time to time, to fully vest or perfect
Applied's IP Rights. Such actions shall include providing documents and
information useful or necessary to (i) register, apply for or maintain any of
Applied's IP Rights; or (ii) pursue or defend any administrative, court, or
other legal proceeding involving any of Applied's IP Rights. In addition, during
the Term, Supplier shall promptly disclose to Applied any of Applied's IP Rights
of which it is aware. Nothing herein shall require Supplier to incur expenses
outside of normal business practices without reimbursement by Applied.

(e)  LICENSE TO MARKS. Applied grants to Supplier a non-exclusive, revocable,
royalty-free, limited and non-transferable license to affix or install on Items
those trademarks, service marks and trade names of Applied's (collectively,
"Marks") that are specified to be installed or affixed under Applied
Specifications for the Items. Such license of Marks is limited, revocable by
Applied, shall not be assigned, sublicensed or transferred in any way. Use by
Supplier of all Marks shall be solely for the benefit of Applied and as directed
by Applied. Supplier shall install and affix the Marks solely in accordance with
Applied's specifications, packaging and labeling requirements and any quality
requirements for the Marks or Items that Applied may establish. Applied may
inspect Supplier's

facilities and examine Items at any time during normal business hours to monitor
or evaluate the quality of the Marks affixed to the Item.

(f)  AGREEMENT WITH EMPLOYEES OR OTHERS. As to any Supplier employee, agent,
Sub-tier Supplier or designated third party who is authorized to receive or
obtain (directly or indirectly) Confidential Information (collectively, the
"Recipients"), Supplier shall ensure that the Recipients have entered into an
agreement with Supplier prior to the Recipient obtaining any Confidential
Information, which obligates the Recipient to (i) hold all Confidential
Information in confidence and not to use the Confidential Information in any
way, except on behalf of Supplier in performing its obligations hereunder for
the benefit of Applied and otherwise protect the Confidential Information upon
substantially similar terms to those set forth in Section 9; and (ii) assign to
Applied all right, title and interest in and to Applied's IP Rights, and take
such other action as may be requested to fully vest or perfect Applied's IP
Rights in Applied. Supplier will provide Applied with copies of such agreements
upon Applied's request.

(g)  ESCROW AGREEMENT FOR VITAL ITEMS. "Vital Item" means an Item that, at any
time, Applied is not able to replace with a reasonably practicable commercial
alternative within six (6) months or less of Applied desiring to do so. Any Item
identified as a Vital Item will be so designated on Attachment 1. Upon Applied's
request, Applied and Supplier agree to execute a mutually agreeable three party
escrow agreement, substantially in the form set forth in Attachment 7 entitled
"Technology Escrow Agreement" located on the Applied Web Site, covering a Vital
Item.

12.    WARRANTY.

(a)  SUPPLIER WARRANTY: Supplier represents and warrants that, for a period of
twenty-four (24) months from the date of delivery to Applied, the Items (i) will
be free from defects in workmanship, material, and manufacture; (ii) will comply
with the requirements of this Agreement, including all Applied Specifications
and manufacturing work instructions; and (iii) will be of merchantable quality
and fit and suitable for the purpose intended by Applied (excluding the Maglev
Items as specified in Attachment 1). Supplier further represents and warrants
that (A) the Items will consist of new (not used or recycled) material, and (B)
Applied shall acquire good and marketable title to the Items, free and clear of
all liens, claims and encumbrances. Further, to the extent that the design of an
Item is Supplier's responsibility, Supplier represents and warrants that such
design will be free from defects.

(b)  SERVICES. Supplier represents and warrants that, for a period of
twenty-four (24) months from delivery to Applied, all services performed in
connection with this Agreement will be performed in a competent, professional
and workmanlike manner, free from defects, and in accordance with the best
professional practices in the industry. For the purposes of this Section, the
results of any service performed by Supplier will be considered included in the
term "Item."

(c)  FREE FROM INFRINGEMENT. Supplier represents and warrants that the Items,
including the manufacture, use and sale of the Items, shall not give rise to,
nor be subject to, any claim or liability for infringement of any intellectual
property rights, including any patent, copyright, trademark, trade secrets,
moral rights, confidential information or any other proprietary or intellectual
property rights, of any third party.

(d)  MISCELLANEOUS WARRANTY ITEMS. From time to time Applied may designate
certain third parties, including its customers, to directly avail itself of
Applied's rights under this Section. Applied may assign and transfer, in whole
or in part, the rights provided by Supplier to Applied under this Section to any
of Applied's customers or any subsequent purchaser of the Items subject to the
provisions of this Section 12. The warranties set forth in this Agreement are in
addition to all other warranties, expressed or implied, and will survive any
delivery, inspection, acceptance or payment by Applied.

(e)  REMEDIES.

     (i) NON-PROPRIETARY ITEMS: If an Item does not meet the warranty
requirements set forth in this Agreement, Applied may, at its option, (i)
require Supplier to correct any defective or nonconforming Item by, at Applied's
option, either repair or replacement; or (ii) return such defective or
nonconforming Item to Supplier and recover from Supplier the Contract Price
thereof; or (iii) correct the defective or nonconforming Item itself and charge
Supplier with the cost of such correction; or (iv) purchase products comparable
to the defective or nonconforming Item in the open market or from other
suppliers, as deemed appropriate by Applied, and, at Applied's option, charge
Supplier with any reasonable cost differential between the price of the Item
under this Agreement and the price paid, which cost may include premium fees for
expedited delivery and administrative costs. In addition, Applied may cancel the
balance of the undelivered, defective or nonconforming Items and/or terminate
this Agreement in accordance with its terms. As to any Item that is repaired,
replaced or corrected under this Section, Supplier's warranty shall continue to
apply to such Item for (A) the full remaining balance of the original
twenty-four (24) month term applicable to such Item, or (B) ninety (90) days
from the date such repaired, replaced or corrected Item is received and accepted
by Applied, whichever period of time is greater. Upon request from Applied,
Supplier shall provide pre-approved returned material authorization ("RMA(s)")
to facilitate return of Items. Applied may notify Supplier of defects and non
conformances and communicate its elected remedy by delivery of notice or in
accordance with the discrepant material report ("DMR") and closed-loop
corrective action processes as set forth in Attachment 8 entitled "Supplier
Corrective Action Request" located on the Applied Web Site.

     (ii) PROPRIETARY ITEMS: At its own expense, Supplier agrees to repair or
replace at its option all defective Items and to use reasonable efforts to
correct all software Items not performing substantially in accordance with
applicable product specifications, provided that Applied has given Supplier
notice of such warranty claim within the warranty period. If Supplier is unable,
after reasonable efforts, to repair or replace such defective Items or to
correct such Items not performing in accordance with applicable product
specifications, Applied's sole remedy shall be the refund of an amount not to
exceed the actual payments received by Supplier for such Items. All repairs will
be done during normal working hours. All replaced parts shall become Supplier's
property. Supplier may require that the Items be shipped to Supplier and
returned to Applied, at Supplier's expense, for warranty service to be
performed. Supplier shall provide pre-approved returned material authorization
("RMA(s)") to facilitate return of Items. Applied may notify Supplier of defects
and non conformances by delivery of notice or in accordance with the discrepant
material report ("DMR") and closed-loop corrective action processes as set forth
in Attachment 8 entitled "Supplier Corrective Action Request" located on the
Applied Web Site. Based on such notification, Supplier agrees to provide, at its
expense, on-site defects and non-conformances support as needed to correct such
defects and non-conformances. If Supplier determines that Items for which
Applied has requested warranty service are not eligible for warranty service,
for any reason, Applied shall pay or reimburse Supplier for all costs of
investigating and responding to such request at the hourly rate of $110. Charges
associated with travel will be billed per the travel time rate below:

     TRAVEL TIME RATE:
     Point to point $75.00/hour (max. travel time charge=8 hours). Irrespective
     of the support personnel labor category, Supplier will not bill Applied for
     travel time in excess of 8 hours, at the hourly rate of $75 per hour. Under
     no circumstances Supplier will bill Applied for travel expenses for on-site
     support performed at Applied's facilities in Austin, Texas.

     FIELD SERVICE EXPENSE CHARGES:
     (1) Car Expenses: US$ 0.40/Mile
     (2) Air Expenses: Actual Cost
     (3) Rent-a-Car or any other transportation: Actual Cost
     (4) Overnights living Accommodations:       US$140.00/Night

The above rates shall apply to the extent that the above rates do not exceed the
individual amounts that would be reimbursed by Applied per its then current
travel policy. Changes to any of the above rates will be made in writing and
mutually agreed to between the parties.

(f)  EXTENDED WARRANTY; EPIDEMIC FAILURE. Without limiting Applied's rights as
specified elsewhere in this Section 12, if an Item is discovered to be defective
or nonconforming at a statistically higher rate than the rate applicable to such
Item as established upon mutual agreement of the Parties and set forth in
Attachment 1, then, at no cost to Applied and at Applied's option, Supplier will
(i) extend the warranty period for such Item for no less than an additional
twelve (12) months from the date on which the warranty for the Item would
otherwise expire, and/or (ii) compensate Applied for mutually agreed direct
expenses attributable to correcting the defect/nonconformance, including field
support, logistics (freight, duties), advanced exchange of a refurbished part,
refurbishment, and any required upgrade cost including qualification.

(g)  TIMING. If Supplier receives notice that an Item is defective or
non-confirming, then Supplier will use the most expeditious manner possible to
effect the action specified by Applied, including the use of overnight delivery
services for shipment of Items to and from Applied. For any Item for which a
repair or replacement timeline is identified in Attachment 1, Supplier will
repair or replace such Item within such timeline. In all events, however, as to
any Items that Applied identifies as "production" or that are delivered by
Supplier for the purposes of production, Supplier will replace or repair the
defective or non-conforming Item within twenty-four (24) hours from receipt of
Applied's request.

(h)  COSTS. Supplier shall be solely responsible for all costs, fees and
expenses in connection with fulfilling its obligations under this Section,
subject to the rate set forth in Section (e)(2) and (f) above, including all
labor, material, parts, shipping, taxes, customs and other costs, fees and
expenses arising from, among other things, the removal, repair, replacement,
reinstallation, inspection, shipping and testing of any defective or
nonconforming Items. If any such costs, fees or expenses are incurred or paid by
Applied (including, for example, the cost to remove such an Item from a customer
site), Applied shall charge and bill such costs to Supplier, and may offset such
costs against amounts otherwise due to Supplier from Applied. All costs
reimbursable to Applied under this Section shall be due and payable on demand.

13.    SUPPLIER REFURBISHMENT SERVICES.

"Refurbishment Services" means services (i) to correct or repair any defect or
non-conformance to an Item that is not covered by Section 12; and (ii) to
retrofit an Item such that it complies with the most current released
Specification for a newly manufactured version of the Item, regardless of
whether the Item is within its warranty period. Upon Applied's request for
Refurbishment Services, Supplier and Applied shall negotiate in good faith to
enter into an arrangement governing the Refurbishment Services in the form of
(A) an Attachment or (B) a separate agreement on substantially similar terms and
conditions as set forth in the then current "Supplemental Flat Rate Repair
Agreement" ("Refurbishment Agreement") located on the Applied Web Site as
Attachment 9. If no pricing for Refurbishment Services is established for an
Item under a Refurbishment Agreement or otherwise, Supplier agrees that charges
for Refurbishment Services for Items no longer under warranty shall not exceed
forty percent (40%) of the price of a newly manufactured Item. Upon request from
Applied, Supplier shall provide pre-approved RMA(s) to facilitate return of
Items.

14.    SUPPLIER PERFORMANCE PLAN.

Applied and Supplier will jointly develop a supplier performance plan in the
form set forth in Attachment 10 entitled "Supplier Performance Plan" located on
the Applied Web Site. Supplier agrees to self-monitor

its performance, at both corporate and operational site levels, against the
performance targets established in the Supplier Performance Plan. At least once
a month, Supplier will submit to Applied its actual performance against
performance targets in the Supplier Performance Plan.

15.    MANUFACTURING REQUIREMENTS.

(a)  FIRST ARTICLE INSPECTIONS. Applied and Supplier shall perform inspections
of the first Item of any part number: (i) ordered by Applied; (ii) following a
change of Specifications (including drawings); or (iii) manufactured after a
change in Supplier's manufacturing location, manufacturing process or any other
change that must first be evaluated and approved by Applied ("First Article").
All First Article inspections shall be completed in compliance with the
requirements set forth in Attachment 11 entitled Supplier First Article
Requirements" located on the Applied Web Site. Supplier shall provide all
documentation necessary for Applied to inspect a First Article.

(b)  DESIGN AND PROCESS CHANGE COMMUNICATION. After Applied has approved the
First Article, Supplier shall not make any change to the design (firmware,
hardware or software) of the Item that may alter the Specifications or the form,
fit, function or interchangeability of parts without first submitting a Supplier
Problem Sheet as set forth in Attachment 12 on the Applied Web Site. Supplier
will not make changes to the manufacturing process of such Items without first
submitting a Supplier Notification Form as set forth in Attachment 13 on the
Applied Web Site.

(c)  OTHER CHANGES AND EQUITABLE ADJUSTMENTS. Applied may, upon notice to
Supplier, submit Engineering Change Orders ("ECOs") or request other changes
within the scope of the Agreement with respect to any of the following: (i)
Specifications; (ii) the place and date of delivery of Items; or (iii) the
place, date and manner of inspection or acceptance of Items. Supplier agrees
that it will use reasonable efforts to accommodate such requests in a timely and
cost effective manner. If any request for such changes causes an increase or
decrease in the cost of or time required for performance of the Agreement,
Applied will consider an equitable adjustment in the Contract Price or delivery
schedule, or both, and the Agreement shall be modified in writing accordingly.
If Applied and Supplier are unable to agree upon an equitable adjustment, then
Applied may remove the affected Item from this Agreement without affecting the
remaining Items. No claim by Supplier for adjustment under this subsection shall
be valid unless in writing and received by Applied within thirty (30) days from
the date of Supplier's receipt of the notice of such change; provided, however,
that such period may be extended upon the written approval of Applied.
Supplier's expectations and responsibilities associated with the ECO process are
set forth in Attachment 14 on the Applied Web Site.

(d)  QUALITY REQUIREMENTS. Supplier shall comply with Applied's quality
requirements set forth in Attachment 15 entitled "Supplier Quality Requirements"
located on the Applied Web Site or shall participate in performance improvement
plans in order to achieve compliance with this Section

(e)  OZONE DEPLETING CHEMICAL. Supplier will not deliver any Items manufactured
with or containing Class I ODCs, as defined under Section 602 of the Federal
Clean Air Act (42 USC Section 7671a). Supplier will certify to Applied that each
shipment of Items does not contain any Class I ODCs.

(f)  SAFETY NOTICES. In addition to any of Supplier's obligations under this
Agreement or imposed by law, Supplier will immediately notify Applied of any
known or suspected safety issues related to an Item (including, without
limitation, component or material issues) by submitting a completed Supplier
Notification Form to Applied as set forth in Attachment 13 on the Applied Web
Site.

<Page>

(a)  VENDOR MANAGED INVENTORY. Participation in this program will be by mutual
agreement of the parties. "Vendor Managed Inventory" or "VMI" means a program
whereby the Parties agree that Supplier, will stock and maintain certain
mutually agreed upon Items at specified locations, with Supplier retaining title
to, and risk of loss with respect to, the Items until such Items are procured by
Applied or its designee in accordance with the terms and conditions of such
program. In the event Applied designates certain Items to be included within the
VMI program ("VMI Items") by providing Supplier with notice of such designation,
Supplier agrees to manufacture and stock such VMI Items in accordance with: (i)
any authorized inventory planning and collaboration tool provided to Supplier by
Applied; and/or (ii) a separate VMI agreement between Applied and Supplier in
form identical or substantially similar to Attachment 16 entitled "Supplier Hub
Amendment to the GSA" located on Applied's Web Site.

(b)  FORECASTS. Applied may periodically issue to Supplier rolling forecasts
setting forth projected demand for Items, whether by specific divisions or
otherwise ("Applied Forecasts"). Applied Forecasts are intended for planning
purposes only and shall not constitute a binding purchase commitment of Applied.

(c)  INVENTORY LEVELS AND TRACKING REQUIREMENTS. Unless otherwise designated in
Attachment 1 or the VMI Agreement, Supplier will maintain a minimum level of one
(1) week of supply and a maximum of two (2) weeks of supply of each VMI Item set
forth in the most recent Applied Forecast, and such minimum to maximum level of
all such VMI Items shall be considered "Finished Good Inventory" under this
Agreement. When Supplier is creating inventory levels to satisfy its minimum or
maximum levels of Finished Good Inventory, any reduction in quantity of Items
that were ordered pursuant to an Authorized Demand Signal or any Authorized
Demand Signal that is later cancelled by Applied shall be returned to Supplier's
inventory and Supplier will adjust its inventory levels accordingly. Supplier
shall monitor and report its work-in-process and VMI Item count to Applied for
all Finished Good Inventory.

(d)  CLAIM FOR REIMBURSEMENT OF EXCESS ITEMS. If Applied has not taken delivery
of any unit of a VMI Item in Finished Good Inventory within twelve (12) months
from the date of Applied's last receipt of any such unit, Supplier may then
submit a claim for reimbursement for such Excess Items to Applied within thirty
(30) days from the end of such twelve (12) month period. Supplier's failure to
submit such a claim within this thirty (30) day period shall constitute waiver
of any claim for reimbursement for such Excess Items and Applied shall be
released from all liability relating to such Excess Item.

(e)  CLAIM FOR REIMBURSEMENT OF OBSOLETE ITEMS. A VMI Item in Finished Goods
Inventory will be considered an "Obsolete Item" when Applied provides notice to
Supplier that such VMI Item is an "Obsolete Item." If Supplier desires to submit
a claim for costs associated with Obsolete Items, then Supplier shall submit a
claim for such obsolete Item(s) within thirty (30) days from the date on which
Applied notifies Supplier that the VMI Item(s) are Obsolete Items. Supplier's
failure to submit such a claim within this thirty (30) day period shall
constitute a waiver of any claim for reimbursement for such Obsolete Items and
Applied shall be released from all liability relating to such Obsolete Items.

(f)  SCOPE OF CLAIM. Applied will not be liable for Finished Goods Inventory
other than as described in this Section. In addition, no claim for reimbursement
or payment for Finished Goods Inventory shall be made in the following
situations: (i) any termination by Applied pursuant to Section 21(a)
(Termination for Default); (ii) if Supplier has introduced design or product
changes; (iii) Supplier errors in production; (iv) if Supplier has been paid for
such Items previously or has made a claim for reimbursement or payment for such
Items previously; or (v) if such Items are "Commercial Off-the-Shelf Items"

21.    TERMINATION.

(a)  TERMINATION FOR DEFAULT.

     (i) Subject to any cure permitted under subsection (ii) below, Applied may
terminate this Agreement, in whole or in part, effective upon delivery of notice
to Supplier, if (i) Supplier fails to deliver Items in accordance with the terms
of this Agreement, including specified delivery times, Item requirements or
other Specifications; (ii) Supplier breaches any other provision of this
Agreement; (iii) Supplier anticipatorily repudiates any material provision of
this Agreement; (iv) Supplier becomes insolvent, files a petition for relief
under a Chapter 7 bankruptcy, insolvency or similar law, makes an assignment for
the benefit of its creditors, or takes any action for (or in anticipation of)
any of the foregoing; or (v) there is a material adverse change in the business,
properties, prospects, operations or condition (financial or otherwise) of
Supplier. Upon any termination pursuant to this Section, Supplier shall: (1)
continue to supply any portion of the Items for which this Agreement is not
cancelled; (2) be liable for additional costs, if any, incurred by Applied for
the purchase of similar goods and services to cover such default; and (3) at
Applied's request, transfer title and deliver to Applied: (a) any completed
Items, (b) any partially completed Items, and (c) all unique materials and
tooling subject or relating to the termination. Termination of the Agreement
under this Section 21(a) shall constitute "cancellation" under the Uniform
Commercial Code as adopted in California.

     (ii) Solely with respect to Supplier's quality performance and/or delivery
obligations related to the Items, Supplier agrees to enter into a mutually
agreed performance improvement plan to cure any quality performance and delivery
obligations related to the Items. At the end of the performance improvement
plan, Supplier shall have thirty (30) days from the date of written notice from
Applied to cure any quality performance and delivery obligations related to the
Items. If the default or breach has not been cured or corrected on or prior to
the expiration of the time period for cure, then Applied may terminate the
Agreement, without giving Supplier any further opportunity to cure, by giving
another Notice of Termination to Supplier. The date of termination of the
Agreement shall be the date on which Supplier receives such Notice of
Termination or such later date for termination specified by Applied in the
second Notice of Termination.

(b)  TERMINATION FOR CONVENIENCE.

     (i) Applied may terminate the Agreement, including any Authorized Demand
Signal, in whole or in part, at any time for Applied's convenience by giving

termination and the conduct required of Supplier in connection therewith.
Supplier will use commercially reasonable efforts to mitigate any damages
incurred in connection with such termination. Within ninety (90) days from the
date on which Supplier receives such notice, Supplier shall deliver to Applied a
written claim for all of Supplier's damages incurred in connection with the
termination ("Termination Charges"), in the form and containing such
documentation as required by Applied. In no event, shall Termination Charges
include any damages relating to Commercial Off-the-Shelf Items.

     (ii) Failure by Supplier to deliver such claim for Termination Charges
within this 90-day period shall constitute a waiver by Supplier of all claims
against Applied as to Termination Charges and a release of all Applied's
liability arising out of such termination.

     (iii) If Applied does not agree with the amount specified in Supplier's
claim for Termination Charges, Applied and Supplier will attempt to agree upon a
reasonable amount for Termination Charges. If Applied and Supplier fail to agree
upon such an amount within six (6) months after receipt by Applied of the claim
for Termination Charges from Supplier, then the Termination Charges will be
conclusively presumed to be the sum of the following as to Items for which the
termination applies (provided that no costs shall be duplicated): (i) the unpaid
Contract Price for all Items delivered to Applied prior to the date of Applied's
termination; (ii) the Contract Price for all Items completed in accordance with
the Agreement but not delivered to Applied prior to the date of termination,
provided such Items are promptly delivered to Applied; (iii) the actual costs
for work-in-process incurred by Supplier, less any costs related to
Commercial-Off-The-Shelf components either manufactured or procured by Supplier,
which are properly allocable or apportionable under GAAP to the terminated
portion of the Agreement, and an amount representing a fair and reasonable
profit on such costs; and (iv) the reasonable, out-of-pocket costs paid by
Supplier to its Sub-tier Suppliers as a direct result of Supplier's cancellation
of work being performed by such sub-tier suppliers or Supplier's termination of
contracts with such Sub-tier Suppliers. Applied's obligation to pay costs
pursuant to clauses (iii) and (iv) above shall be subject to Supplier's
obligation to use commercially reasonable efforts to mitigate any such costs.

     (iv) This Section 21(b) sets forth Supplier's sole remedies, and Applied's
entire liability to Supplier, in the event of a termination by Applied for
convenience, excluding any termination or cancellation of a VMI Item, for which
Supplier's sole remedy and Applied's entire liability is as set forth in Section
16.

(c)  POST TERMINATION CONSEQUENCES. On the date of termination or expiration of
the Agreement for any reason, Supplier shall (i) stop work being performed by
Supplier pursuant to the Agreement, (ii) cancel orders for parts and/or
materials with Supplier's Sub-tier Suppliers and cease ordering any such parts
and/or materials, (iii) cancel work being performed by Supplier's Sub-tier
Suppliers, (iv) at Applied's request, assign to Applied Supplier's interests in
contracts with Supplier's Sub-tier Suppliers, (v) furnish Applied with release
of claims from Supplier's Sub-tier Supplier resulting from orders and/or work
canceled by Supplier, (vi) protect all property in which Applied has or may
acquire an interest, (vii) fully cooperate with Applied to minimize any adverse
effect on Applied or its customers, and (viii) perform those other obligations
set forth in this Agreement upon the termination or expiration of this
Agreement.

ADVISED OF THE POSSIBILITY OF ANY OF THE FOREGOING DAMAGES. NOTWITHSTANDING THE
FOREGOING, THE LIABILITY LIMITATION IN THIS SECTION 22 SHALL NOT APPLY TO CLAIMS
OF WILLFUL INFRINGEMENT OF EITHER PARTY'S INTELLECTUAL PROPERTY RIGHTS.

23.    INDEMNITY BY SUPPLIER.

(a)  Supplier shall defend, indemnify and hold harmless Applied from and against
any and all claims, demands, suits, actions, losses, penalties, damages (whether
actual, punitive, consequential or otherwise), authorized settlements, and all
other liabilities and associated costs and expenses, including attorney's fees,
expert's fees, costs of investigation and other costs of litigation (all of the
foregoing being collectively called "Indemnified Liabilities"), arising solely
out of or relating to (i) Supplier's breach of any provision of the Agreement;
(ii) any negligent, grossly negligent or intentional acts, errors or omissions
by Supplier, its employees, officers, agents or representatives; or (iii) strict
liability or products liability with respect to or in connection with the Items;
(iv) any claim by a Sub-tier Supplier against Applied; or (v) the actual or
alleged infringement or misappropriation of patent, copyright, trademark, trade
secret rights, confidential information, proprietary rights, or other rights of
a third party, except to the extent that the infringement or misappropriation
was unavoidably caused by Supplier's compliance with a detailed design furnished
and required by Applied. THE INDEMNITY BY SUPPLIER IN FAVOR OF APPLIED SHALL
EXTEND TO APPLIED, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND
REPRESENTATIVES AND SHALL INCLUDE, AND IS INTENDED TO INCLUDE, INDEMNIFIED
LIABILITIES WHICH ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION TO BE THE
RESULT OF ACTS OR OMISSIONS OF SUPPLIER AS A JOINT TORTFEASOR. IF SUPPLIER IS
LIABLE ONLY AS A JOINT TORTFEASOR, THEN SUPPLIER'S LIABILITY SHALL NOT EXTEND TO
THAT PORTION OF LIABILITY DETERMINED BY THE COURT TO BE THE RESULT OF ACTS OR
OMISSIONS OF APPLIED. The indemnity of Supplier as to Indemnified Liabilities
under clauses (ii) and (iii) above, shall not extend to liabilities and damages
that are caused by the sole negligence of Applied, and as to Indemnified
Liabilities under clause (v), shall not extend to liabilities and damages that
are caused as described in the "except to the extent" term of such clause (v).
In addition to Supplier's obligations as to Indemnified Liabilities that arise
under clause (v), Supplier shall, at Applied's option (1) procure for Applied
and its customers the right to continue to use, sell and resale any affected
Item, (2) with respect to a claim for infringement, modify the affected Item so
that it is no longer infringing, or (3) replace any affected Item with a
non-infringing good or service comparable to the affected Item. If none of these
alternatives are possible, Applied shall have the right to return or upon mutual
agreement, destroy, any affected Items for a full refund of the purchase price,
plus applicable transportation costs.

(b)  In the event of any such Indemnified Liabilities, Applied shall (i)
promptly notify Supplier; (ii) at Supplier's expense, reasonably cooperate with
Supplier in the defense of such claim; and (iii) not settle any such Indemnified
Liabilities without Supplier's written consent, which shall not be unreasonably
withheld or delayed. Supplier shall keep Applied informed at all times as to the
status of Supplier's efforts and consult with Applied and/or its counsel
regarding such efforts. Supplier shall not settle any such claim without the
prior written consent of Applied, which shall not be unreasonably withheld or
delayed.

24.    IMPORT AND EXPORT REQUIREMENTS.

(a)  GENERAL. Supplier shall comply with all applicable export control laws or
regulations promulgated and administered by the laws of the United States or the
government of any other country with jurisdiction over the parties or the

Items to any person or destination when such export, re-export or disclosure is
in violation of Export Laws. Supplier will provide Applied with any and all
information that may be required to comply with Export Laws, including
applicable "Export Control Classification Numbers," documentation substantiating
U.S. and foreign regulatory approvals for the Items, and information required by
Customs officials to substantiate the value of imported Items including any
adjustments in valuation attributable to "assists" as defined by U.S. Customs
regulations. All required export and import information shall be sent to the
attention of: Manager, Customs Compliance, Applied Materials, 2881 Scott Blvd.,
M/S 2041, Santa Clara, CA 95050; or any agent so designated by Applied.

identifying for each Item delivered the (i) Applied part number and (ii) the
country of manufacture. This data shall be provided to Applied upon Applied's
request and in any event, within fifteen (15) days after each month end. If
Supplier is a U.S. manufacturer of any Item supplied to Applied, as defined by
U.S. Customs regulations, Supplier shall, on an annual basis and in accordance
with Applied's written instructions, provide Applied with a signed
manufacturer's affidavit.

(c)  DUTY DRAWBACK. Supplier will provide Applied or its agent with U.S. Customs
entry data and information that Applied determines is necessary for Applied to
qualify for duty drawback. Such data shall include information and receipts for

unique part numbers, lot numbers and any other data which will assist Applied in
identifying imported Items sold to Applied shall also be provided. At the time
of delivery of the Items, but in no event later than thirty (30) days after each
calendar quarter, Supplier will provide said documents accompanied by a
completed Certificate of Delivery of Imported Merchandise or Certificate of
Manufacture and Delivery of Imported Merchandise (Customs Form 331) as

All policies must be primary and non-contributing and shall include Applied as
an additional insured. Supplier also waives all rights of subrogation. Supplier
will require and verify that each of its Sub-tier Suppliers carries at least the
same insurance coverage and minimum limits of insurance, as Supplier is required
to carry pursuant to the Agreement. Supplier shall notify Applied at least
thirty (30) days prior to the cancellation or implementation of any material
change in the foregoing policy coverage that would affect Applied's interests.

26.    ELECTRONIC COMMUNICATION. The Parties acknowledge that they are relying
upon electronic means, in addition to email and facsimile transmissions, to
exchange Authorized Demand Signals and other delivery and order information.
Supplier agrees to communicate with Applied using the standards designated by
Applied. To the extent communication through electronic means is inaccessible or
made otherwise unavailable due to technical difficulties or due to the effect of
any law or regulation governing electronic transactions, the Parties agree (i)
that any delivery or order information received electronically prior to the date
of such inaccessibility or unavailability will remain valid; and (ii) to
conduct, to the extent possible, their transactions by other than electronic
means.

27.    MISCELLANEOUS.

(a)  ASSIGNMENT. This Agreement shall be binding on, and inure to the benefit
of, the Parties and their respective permitted assigns. Supplier shall not
assign or otherwise transfer this Agreement or any of Supplier's rights or
obligations hereunder, in any manner, including by way of merger, exchange or
combination, or sale of fifty percent (50%) or more of Supplier's capital stock
or similar ownership interests, or sale of all or substantially all of its
assets or the assets of any line of business involved in Supplier's performance
of this Agreement (each a "Change in Control"), or otherwise, without the prior
written consent of Applied. Applied may assign or otherwise transfer this
Agreement or any of its rights or obligations hereunder, in whole or part, at
any time.

(b)  CHANGE OF CONTROL. Supplier will notify Applied immediately of Supplier's
intent to effect any Change of Control or any sale of ten percent (10%) or more
of Supplier's capital stock or similar ownership interest of Supplier. In no
event shall such notice to Applied be later than the date Supplier enters into
negotiations with respect to a letter of intent, term sheet (or other statement
of transaction terms) or definitive agreement regarding such event, whichever is
earliest.

(c)  WAIVER. If either Party fails to insist on performance of any term or
condition, or fails to exercise any right or privilege hereunder, such failure
shall not constitute a waiver of such term, condition, right or privilege.

(d)  SURVIVAL OF OBLIGATIONS. Termination or expiration of this Agreement will
not relieve either Party of its obligations under Sections 8(c), 9, 11(a) - (d),
12, 19, 20(d) - (f), 21 - 24, 27(c) - (e), (g), (i) - (k), (n), (o), (q), (r),
(s) nor will termination or expiration relieve the Parties from any liability
arising prior to the date of termination or expiration.

(e)  SEVERABILITY. Any provision of this Agreement that is held unenforceable or
invalid for any reason by a court of competent jurisdiction shall be severed
from this Agreement, and the remainder of the Agreement shall continue in
effect; provided, that such unenforceable or invalid provision shall be given
effect to the maximum extent then permitted by law.

(f)  GENERAL COMPLIANCE WITH LAWS AND EEO REGULATIONS. Supplier represents,
warrants and agrees that (i) Supplier's execution, delivery and performance of
this Agreement will not conflict with or violate any applicable law, rule,
regulation, order, decree, or ordinance; and (ii) Supplier shall comply with the
requirements of 41 CFR Sections 60-1.4(a) -250.5(a), and -741.5(a), if
applicable, relating to equal opportunity clauses pertaining to government
contracts.

(g)  COMPLIANCE WITH SECURITIES LAWS. Supplier agrees that certain of the
Confidential Information, including new product plans and Internal Applied Data,
may be "material, nonpublic information" for purposes of federal or state
securities laws, the awareness of which prohibits Supplier and its employees,
contractors, representatives and agents from (i) buying or selling Applied's
securities (stock, options, etc.) (i.e., "insider trading") and (ii) passing
Confidential Information on to anyone who may buy or sell

Applied securities (i.e., "tipping"), until after the information has been
disclosed to the public and absorbed by the market. Without limiting any of
Supplier's other obligations under this Agreement, Supplier will comply with all
federal and state securities laws prohibiting insider trading and tipping, and
shall immediately notify Applied in the event of any insider trading or tipping
by Supplier or its employees, contractors, representatives or agents of which it
becomes aware.

(h)  NO GRATUITY; FCPA. Supplier will not offer or give any gratuity to induce
any person or entity to enter into, execute or perform the Agreement or any
other agreement with Applied. Supplier further represents that it has knowledge
and understanding of the Foreign Corrupt Practices Act of the United States of
America, and that no principal, partner, officer, director or employee of
Supplier is or will become an official of any governmental body of any country
(other than the U.S.) in which Supplier provides goods or services for Applied
during the Term. Supplier agrees that it shall not, in the conduct of its
performance under this Agreement, and with regard to any funds, assets, or
records relating thereto, offer, pay, give, or promise to pay or give, directly
or indirectly, any payment or gift of any money or thing of value to (i) any
non-U.S. government official to influence any acts or decisions of such official
or to induce such official to use his influence with the local government to
effect or influence the decision of such government in order to assist Supplier
in its performance of its obligations under this Agreement or to benefit
Applied; (b) any political party or candidate for public office for such
purpose; or (ii) any person if Supplier knows or has reason to know that such
money or thing of value will be offered, promised, paid, or given, directly or
indirectly, to any official, political party, or candidate for such purpose. In
the event of any breach by Supplier of this Section, (1) Applied will have a
lawful claim against Supplier for any funds and/or the value of property paid by
Supplier in breach of this provision, (2) Supplier will automatically surrender
any claim for fees and other payments due under this Agreement, and (3) this
Agreement will automatically be rendered void.

(i)  APPLICABLE LAW, JURISDICTION, VENUE. This Agreement shall be governed by

rules. Items shall be deemed and shall qualify as goods under the Uniform
Commercial Code as adopted in California. Any suit arising out of this
Agreement, at law or in equity, shall be brought in a state or federal court in
California or Texas, the jurisdiction of which state or federal court includes
Santa Clara County, California or Travis County, Texas, provided that such court
has jurisdiction over the subject matter of the suit. Each Party consents to
personal jurisdiction in the above courts. Supplier further consents to such
venue as Applied selects in any of such courts.

(j)  CISG. With respect to transactions to which the 1980 United Nations
Convention on Contracts for the International Sale of Goods ("CISG") would
otherwise apply, the rights and obligations of the parties under the Agreement
shall not be governed by the provisions of the CISG.

(k)  GENERAL REPRESENTATIONS. Supplier represents and warrants as follows: (i)
Supplier is duly organized, validly existing, and in good standing under the
laws of the jurisdiction of its organization; and (ii) Supplier's execution and
delivery of this Agreement and Supplier's performance of its obligations
hereunder will not (1) violate any provision of the charter, bylaws or other
governing document of Supplier, or (2) conflict with, result in a breach of, or
constitute a default under, any other agreement or arrangement by which Supplier
is bound.

(l)  FORCE MAJEURE. If and to the extent that a Party's performance of any of
its obligations pursuant to this Agreement is prevented, hindered or delayed by
fire, flood, earthquake, elements of nature or acts of God, acts of war,
terrorism, riots, civil disorders, rebellions, revolutions, strikes, labor
disputes or any other similar cause beyond the reasonable control of such Party
(each, a "Force Majeure Event"), then the non-performing, hindered or delayed
Party shall be excused for such non-performance, hindrance or delay, as
applicable, of those obligations affected by the Force Majeure Event for as long
as such Force Majeure Event continues; provided, that such Party continues to
use commercially reasonable efforts to

recommence performance whenever and to whatever extent possible without delay,
including through the use of alternate sources, workaround plans or other means.
Notwithstanding the preceding sentence, if the Force Majeure Event continues for
a period of more than thirty (30) days, Applied may terminate this Agreement
effective upon delivery of notice to Supplier and such termination shall be
deemed a termination pursuant to Section 21(a)(ii). The Party whose performance
is prevented, hindered or delayed by a Force Majeure Event shall promptly notify
the other Party in writing of the occurrence of a Force Majeure Event and
describe in reasonable detail the nature of the Force Majeure Event.

(m)  NO AGENCY. Each Party shall be deemed to be an independent contractor and
not an agent, joint venturer or representative of the other Party, and neither
Party may create any obligations or responsibilities on behalf of or in the name
of the other Party. Each Party also agrees not to make false or misleading
statements, claims or representations about the other Party, its products or the

Agreement or in law or in equity.

Agreement shall be in writing (unless otherwise expressly stated) and shall be

                                    RECITALS

          A.   Applied and Supplier have entered into a supply agreement (the

            Applied is not able to replace with a reasonably practicable
            commercial alternative within six (6) months or less of Applied
            desiring to do so. Any Item identified as a Vital Item will be so
            designated on Attachment 1 of the Supply Agreement.

       (b)  "Item" or "Items" means a component, equipment, material,
            subassembly or other goods and related software and services
            specified in (i) Attachment 1 of the Supply Agreement, (ii) an
            Authorized Demand Signal, or (iii) a purchase order delivered by

       product, Confidential Information, and/or other information and (ii) any
       improvements, enhancements or modifications related thereto, which are
       made, conceived or developed by Applied, Supplier or its Sub-tier
       Suppliers, either alone or with others, arising out of or related to the
       work performed under the Supply Agreement or based on or derived from the
       foregoing.

       (d) "Supplier IP Rights" means all rights, whether registered or
       unregistered, arising from or relating to patents, copyrights, trade
       secrets, trade marks, service marks, trade names, mask works, moral
       rights and other proprietary rights in any jurisdiction in and to (i) all
       inventions, discoveries, works of authorship, know-how, technical

       independent of Applied's personnel, Applied's IP Rights, and work
       performed under the Supply Agreement, either prior to or after the
       Effective Date of the Supply Agreement.

2. ESCROW MATERIALS. "Escrow Materials" means all materials required to
manufacture the Vital Items, including but not limited to the materials
identified in Exhibit B (Escrow Materials) to this Agreement. All Escrow
Materials must be in English.

3. DEPOSITS. Within ten (10) days after the execution of this Agreement by all
Parties, Supplier will deliver to the Escrow Agent a copy of the Escrow
Materials in existence as of the date of execution of this Agreement (the
"Initial Deposit"). In addition, within thirty (30) days after any Supplier
completes any substantial modification to any Vital Item or to the methods of
manufacturing any Vital Item, Supplier will deliver a complete set of updated
Escrow Materials for such Vital Item (a "Subsequent Deposit") to the Escrow
Agent. Notwithstanding the foregoing, Supplier will make a Subsequent Deposit
containing the then-current set of Escrow Materials for all Vital Items at least
once every six (6) months or as otherwise may be required under the Supply
Agreement. Supplier shall deliver a replacement copy of the Escrow Materials
within ten (10) days of receipt of any notice issued by the Escrow Agent
pursuant to PARAGRAPH 5 (Storage of Materials; Inspection). Once deposited with
the Escrow Agent, no Escrow Materials will be destroyed or released except as
provided in PARAGRAPH 7 (Term) or PARAGRAPH 11 (Delivery of Escrow Materials to
Applied).

4. RECEIPTS BY ESCROW AGENT. Supplier will furnish to the Escrow Agent Exhibit
Bs in triplicate describing the Initial Deposit and each Subsequent Deposit. The
Escrow Agent will issue a receipt in the form of a dated and signed Exhibit B
for all Escrow Materials received and accepted by Escrow Agent and will forward
copies of such Exhibit Bs to both Applied and Supplier. Upon each deposit of the
Escrow Materials, the Escrow Agent shall perform the inspection tests required
in accordance with its then standard inspection processes. During the
inspection, the Escrow Agent shall compare the quantity, type, labeling, and
legibility of the labels of the Escrow Material to the Exhibit B. If a
discrepancy exists between the labeling of

                                       2.
<Page>

the Escrow Material and Exhibit B, Escrow Agent will note the discrepancy on the
Exhibit B, date and sign the Exhibit B with exceptions noted, and mail a copy
thereof to Applied and Supplier. If Applied or Supplier deem necessary, Supplier
will correct the discrepancy by depositing corrected Escrow Materials and
Exhibit B.

5.   STORAGE OF MATERIALS; INSPECTION. The Escrow Agent will establish under its
control a receptacle for the purpose of storing the Escrow Materials in
safekeeping in an appropriate physical facility and will allow the inspection of
the Escrow Materials by an independent third party designated by Applied and
Supplier to perform audits (`Independent Agent') to confirm that each Deposit is
complete or, at the Independent Agent and/or Applied's request and expense, will
perform such inspection itself. Any inspection by the Independent Agent will be
done in the presence of an authorized representative of the Escrow Agent. The
Independent Agent will notify Supplier at least ten (10) days before any
requested inspection and Supplier will have the right to attend the inspection
as scheduled by the Escrow Agent and the Independent Agent. Authorized
representatives of the Escrow Agent will have access to the Escrow Materials to
the extent necessary for the Escrow Agent to perform its obligations under this
Escrow Agreement. The Escrow Agent shall notify Applied and Supplier if it
becomes aware at any time during the term of the Escrow Agreement that the copy
of the Escrow Materials held by it has been lost, damaged or destroyed.

6.   RECORDS. The Escrow Agent will keep complete written records of the
activities undertaken and the materials prepared and delivered to the Escrow
Agent pursuant to this Escrow Agreement. Supplier or Applied will be entitled at
reasonable times during normal business hours, and upon reasonable notice to the
Escrow Agent, to inspect the records of the Escrow Agent with respect to the
Escrow Materials and to inspect the facilities of the Escrow Agent. (Applied or
Supplier, whomever is paying) will pay for all of Escrow Agents expenses
regarding the audit inspection including but not limited to third party travel,
wages, and lodging associated with any non local travel, provided that Applied
has approved estimates of expenses in advance of Escrow Agent providing
services. Upon the completion of each deposit and upon the written request of
either Applied or Supplier, the Escrow Agent shall forward to both Applied and
Supplier a copy of the Exhibit B recording the inventory of the latest deposit.
Escrow Agent will issue to Supplier and Applied a report profiling the account
history at least semi-annually. The Escrow Agent may provide copies of the
account history pertaining to this Agreement upon the request of any party to
this Agreement.

7.   TERM. This Escrow Agreement will be effective upon execution by all three
Parties and will terminate only if and when (a) all of the Escrow Materials are
delivered to Applied pursuant to PARAGRAPH 11 (Delivery of Escrow Materials to
Applied), (b) any arbitration initiated under PARAGRAPH 17 (Arbitration) has
been completed upon notification by arbitrator (unless the result of such
arbitration is that the Escrow Materials are to be returned to the Escrow Agent,
in which case this Escrow Agreement will remain in effect); (c) upon joint
instruction that Supplier has ceased doing business with Applied and/or
Applied's subassemblers, and (d) if Escrow Agent does not receive fees for
maintaining the escrow in accordance with Paragraph 18. Subassemblers has the
meaning set forth in the Supply Agreement. Any Escrow Materials with the Escrow
Agent after termination shall be returned to Supplier.

hereby specifically authorized, to provide the Escrow Materials to Applied
immediately upon written notice by Applied (a "Release Notice") that one or more
of the Release Events has occurred, and to provide Supplier with a copy of the
Release Notice. The Release Notice must identify which Release Event or Release
Events have occurred. If such notice does not identify Release Event by Section

confirms the specific Release Event.

12.  BANKRUPTCY. Supplier and Applied acknowledge that this Escrow Agreement is
an "agreement supplementary to" the Supply Agreement as provided in Section
365(n) of Title 11, United States Code (the "Bankruptcy Code"). Supplier
acknowledges that if Supplier, as a debtor in possession or a trustee in
bankruptcy in a case under the Bankruptcy Code, rejects the Supply Agreement or
this Escrow Agreement, Applied may elect to retain its rights under the Supply
Agreement and this Escrow Agreement as provided in Section 365(n) of the
Bankruptcy Code. Upon written request of Applied to Supplier or the bankruptcy
trustee, Supplier or such bankruptcy trustee will not interfere with the rights
of Applied as provided in the Supply Agreement and this Escrow Agreement,

distribute, import, improve, and offer for sale Vital Items. This license

or otherwise change the Supplier IP Rights. Applied agrees that it will refrain
from exercising its rights under the foregoing license unless and until a
Release Event has occurred.

diligence in accordance with at least the high level of care with which the
Escrow Agent protects its own valuable materials, but in no case shall such care
be less than best practices generally accepted by other service providers within
the escrow industry. Except as provided in PARAGRAPH 4 (Receipt by Escrow Agent)

to verify that the Escrow Materials deposited with the Escrow Agent by Supplier
do, in fact, consist of those items that Supplier is obligated to deliver under
this Escrow Agreement or (b) to verify the existence, relevance, completeness,
currency, or accuracy of the Escrow Materials. The Escrow Agent will be entitled
to act in good faith reliance upon any written instruction, instrument, or
signature believed in good faith to be genuine and to assume in good faith that
any person purporting to give any writing, notice, advice, or written
instruction in connection with, or relating to, this Escrow Agreement has been
duly authorized to do so.

delivered to Applied pursuant to Paragraph 11, Applied will return the original
Escrow Materials to the Escrow Agent and certify in writing that it has
destroyed any copies it made of such Escrow Materials. The Escrow Agent agrees
to maintain all Escrow Materials coming into its possession under this Agreement
in strictest confidence.
The Escrow Agent shall have no right to use either the Supplier's or Applied's
trademarks or trade names or to refer to this Agreement or the services

information on suitable and accessible media to enable a reasonably skilled
manufacturing professional to understand, manufacture, maintain and support the

17.  ARBITRATION. After the Escrow Agent's delivery of the Escrow Materials to
Applied pursuant to PARAGRAPH 11 (Delivery of Escrow Materials to Applied), if

Agent, such dispute will be settled by arbitration before a single arbitrator
selected in accordance with the rules of the American Arbitration Association

days following Applied's delivery of a Release Notice to the Escrow Agent
pursuant to PARAGRAPH 11 (Delivery of Escrow Materials to Applied), in

party responsible for payment of the Escrow Agent's fees at least 60 days prior
to any increase in fees. For any service not listed on the Escrow Agent's
standard fee schedule, the Escrow Agent will provide a quote prior to rendering
the service, if requested. The Escrow Agent shall not be required to perform any

hold harmless Escrow Agent from any and all claims, demands, actions, damages,
arbitration fees and expenses, costs, attorneys fees and other liabilities which
may be incurred by Escrow Agent, prior to, and in the event of adjudication,
settlement or award, arising from any third party claims or claims in litigation
or arbitration arising from the performance of its duties hereunder, provided
that such litigation or arbitration shall not have resulted from any action
taken or omitted by Escrow Agent for which it is negligent, or have engaged in
willful misconduct or breached its obligations as set forth in this Agreement.

20.  DISCHARGE OF ESCROW AGENT. In the event that renewal fees have not been
paid by Supplier, and Applied has declined the opportunity to pay the renewal
fees, the Escrow Agent may resign and be discharged from its duties or
obligations hereunder by giving notice in writing of such resignation to
Supplier and Applied specifying a date when such resignation will take effect,
which date must be at least sixty (60) days after the date of receipt of such
notice. Prior to the effective date of such resignation, Supplier will arrange

escrow agent having substantially the same terms as this Escrow Agreement. When
Supplier notifies the Escrow Agent of the name and address of the new escrow

date of Applied's receipt of Escrow Agent's resignation notice, the Escrow Agent

18.  COMPENSATION. The Escrow Agent is entitled to be paid its standard fees and
