it sees fit. Nothing in this Agreement will prevent Maxtor from procuring
Products or the same or substantially similar goods or materials from other
sources than Komag or from providing the same itself, provided that the
confidentiality and intellectual property rights terms of this Agreement are not
breached.
1.2 Warranty. Each of Komag’s warranties made hereunder is materially relied
upon by Maxtor in entering into this Agreement or any Order.
1.2.1 Authority Warranty. Each party represents and warrants that all corporate
action necessary for the authorization, execution and delivery of this Agreement
by such party and the performance of its obligations under this Agreement has
been taken. Further, each party represents and warrants that neither the
execution of this Agreement nor any performance of this Agreement shall conflict
with or be prohibited by any interest, agreement, obligation, contract, order,
law, regulation, or duty, oral or written, to which it is a party or by which it
is bound.
1.2.2 Product Warranty. Komag warrants the Product, upon delivery and for
fifteen (15) months thereafter, to:

REQUEST. OMISSIONS ARE DESIGNATED AS [****]. A COMPLETE VERSION OF THIS EXHIBIT
HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.
     (ii) not infringe any patent, trademark, copyright, trade secret, or other
intellectual property right of any third person;
     (iii) be newly manufactured and not used or reworked (except as provided in
Maxtor-approved procedures);
     (iv) be free from defects in workmanship and materials except as defined in
and allowed by the Product Specification;
     (v) conform to applicable specifications, drawings, or other descriptions

     (vi) possess the qualities of goods which Komag has held out to Maxtor as a
sample or model;
     (vii) initially meet and continue to meet Maxtor’s qualification criteria
and standards (this specific warranty shall not apply to any Order which is
declared a “Risk Buy” in writing by Maxtor); and
     (viii) be contained or packaged according to Maxtor’s specifications as
agreed and in effect at the time this Agreement is executed, or as may be
mutually agreed thereafter.
The above is the Product Warranty (“Product Warranty”). A unit of Product which
meets all of the standards of the Product Warranty shall be a Conforming Product
(“Conforming Product”). Replaced Product shall be subject to the provisions of
this warranty to the same extent as the original Product except that the
warranty period shall run from its delivery date.
1.2.4 Scope of Warranty. The above warranties shall be construed as conditions
as well as warranties and shall be cumulative.
1.2.5 Warranty Disclaimer. Except for the warranties set forth above, Komag
grants no warranties, either express or implied, for the Product, and disclaims
all implied warranties including without limit any implied warranties of
merchantability or fitness for a particular purpose.
1.3 Remedies.
1.3.1 Product Remedies. In the event that Maxtor determines that a Product is
not a Conforming Product, and Komag has had forty eight (48) hours notice or if
Komag must receive parts from Maxtor, ninety-six (96) hours notice of such
determination, during which time Komag may take such actions as it desires to
confirm for itself Maxtor’s determination, then Maxtor may elect to have the
Product replaced or to receive a full refund for the Product as follows:
     (i) Komag agrees to replace any Product not Conforming to the requirements
of this Agreement when requested by Maxtor. If Komag, upon such notice of
defect, fails to replace the Product, Maxtor may do so without further notice
and Komag shall reimburse Maxtor for actual direct manufacturing costs incurred
to replace the Media in such actions. No inspection, test or approval of any
kind, including approval of designs, shall affect Komag’s obligation under this
Agreement.
     (ii) Komag agrees to refund the purchase price (if payment has been made by
Maxtor) or to credit Maxtor’s account for such purchase price (if payment has
not been made by Maxtor) of any Product not Conforming to the requirements of
this Agreement when requested by Maxtor.
     (iii) Product which has been used or rejected shall not thereafter be
tendered for acceptance unless the former use or rejection is identified by
Komag in writing and Maxtor accepts such tender in writing.
1.4 Prices.
1.4.1 Product Price.
     (A) The purchase price for Product paid to Komag by Maxtor for the balance
of 2003 and for all of 2004 shall be as detailed in Exhibit B “Komag Expansion
Pricing Matrix”. This pricing shall be on a not-to-exceed basis, and it is
anticipated that yield improvements and/or decreases in material costs will
provide lower prices from Komag to Maxtor on a Product by Product basis. The
prices in Exhibit B shall be reviewed at least monthly by Komag and Maxtor, with
the specific intent of finding ways to reduce said pricing.
     (B) Komag agrees to diligently pursue and to work cooperatively with Maxtor
in pursuing cost reductions, which shall be reflected in prompt reductions to
the prices in Exhibit B when such cost reductions are implemented. Such price
reductions shall not apply to inventory declared by Komag, except as mutually
agreed.
     (C) [****] .
     (D) It is understood and agreed that any cancelled or rejected portion of
an Order which is cancelled or rejected because of Komag’s fault, including
without limit warranty, inspection, deliveries, shortages, or epidemic, shall
nevertheless be counted as purchased for purposes of determining Maxtor’s right
to any discounts or other considerations based on quantity purchased.
     (E) [****] .
     (F) Komag agrees that prices for new technologies, such as perpendicular
magnetic recording

5

--------------------------------------------------------------------------------

 

(“PMR”) and synthetic anti-ferromagnetic coating (“SAF” or “AFC”) will be based
upon the assumption that Komag’s costs shall be comparable to MMC’s costs, and
that such MMC costs shall be predicated on MMC using labor costs equivalent to
the lesser of MMC’s actual labor costs or the labor costs actually incurred by
KMS. Maxtor will help facilitate communication between MMC and Komag should
there be wide discrepancies in costs for new technologies.
     (G) Maxtor agrees that the prices detailed in Exhibit B include process
improvement plans Komag has made known to Maxtor at the time of execution of
this Agreement, as detailed in Exhibit C.
1.4.2 Terms of Sale. The terms of sale are as follows:
     (i) For sales to Maxtor’s research, engineering, qualification,
development, or NPI facilities, or in any case which is not Just in Time (JIT):
Title, and risk of loss or damage to the Products passes from Komag to Maxtor,
at Maxtor’s receiving dock. Maxtor selects the common carrier and pays for
freight, but Komag is responsible for all other shipment and pre-delivery costs
including without limit insurance and packing according to the terms of this
Agreement. If the sale involves international shipment from Komag to Maxtor,
then the terms of sale are D.D.P. Maxtor’s designated delivery location; and
Komag is responsible for importation and all customs, taxes, imposts, or duties.
     (ii) For sales to Maxtor’s factory facilities under Just In Time (“JIT”)
terms:
Title, and risk of loss or damage, passes from Komag to Maxtor at Maxtor’s
receiving dock. Maxtor pays for all freight from Komag’s origin to the JIT
warehouse, but Komag is responsible for all other shipment and pre-delivery
costs including without limit inventory, stocking, all warehouse expense,
insurance, packing, and shipment from warehouse to Maxtor according to the terms
of this Agreement. Maxtor selects the common carrier. Excess transportation
costs resulting from Komag’s failure to comply with the provisions of this
Agreement will be paid by Komag. Terms of sale are D.D.U. Maxtor’s designated
delivery location.
ARTICLE II — PROCEDURES
2.1 Qualification.
2.1.1 Qualification. The respective obligations of the parties pursuant to this
Agreement shall be subject to the successful qualification of Komag’s Product
and its manufacturing process in Maxtor’s HDD and with Maxtor’s customers, as
Maxtor deems necessary. Maxtor and Komag shall cooperate to set up the necessary
processes and procedures to accomplish and facilitate such qualification.
Successful qualification means successful qualification with each specified
head. After Maxtor’s approval or acceptance of the initial qualification
prototypes of the Products, Komag shall not make any changes in the Product
design or material according to the Specification, any processes documented in
the mutually agreed Process Management Plan; or in plant location.
2.1.2 Changes. Komag shall use its best efforts to promptly notify Maxtor in
writing of any change in Product design or material according to the
Specification; production process documented in the mutually agreed Process
Management Plan; or in plant location in order to allow it to re-qualify the
Product, before any Product is manufactured by the new design, material, process
or in the new location and sold to Maxtor. Failing such written notice and
re-qualification, Komag will be responsible for Maxtor’s damages up to the cost
of the affected Product and any direct expense incurred for the rework of
Maxtor’s HDD. Any Product delivered to Maxtor after such change and without
re-qualification may be rejected by Maxtor for a full refund.
2.2 Tooling. Unless otherwise specified in this Agreement, all tooling and/or
all other articles required for Komag’s performance under this Agreement shall
be furnished by Komag, maintained in good condition and replaced when necessary
at Komag’s expense. If Maxtor agrees to pay Komag for special tooling or other
items either separately or as a stated part of the unit price of Products, title
to same shall be and remain in Maxtor upon payment, and the tooling shall be
treated as property of Maxtor, furnished by Maxtor to Komag.
     (A) Maxtor agrees to pay for the prototype tooling required to establish
the development of new form factors in KUS. This includes tools and cassettes
required to transport substrates to Komag, media within Komag’s process, and
finished media to Maxtor. Notwithstanding anything to the contrary in this
paragraph, such prototype tooling shall not exceed $250K for any one form factor
for any one program, and Maxtor agrees to pay fifty percent (50%) of such
tooling cost upon placement of purchase order, and the balance of fifty percent
(50%) of such tooling cost upon shipment of first samples of material to Maxtor.
Komag agrees that if, for any reason, it should not qualify on a program for
which Maxtor has authorized and made payments for tooling, Komag shall reimburse
Maxtor for said tooling costs. Maxtor’s payments for said tooling shall be made
in accordance with the payment terms and conditions in effect between the two
companies at the time each payment is due.

6

--------------------------------------------------------------------------------

 

     (B) Komag will pay for all volume tooling, including any special tooling
for form factors new to the Maxtor dedicated Tools at Komag, and make ready said
tooling as required in KMS three (3) months prior to the start of DVT.
2.3 Commitment, Forecasts, and Orders.
2.3.1 Volume Commitment.
     (A) Komag agrees to exclusively sell Maxtor the output from the Intevac
Tools, Additive Tools, and Incremental Tools and the output from any other
Intevac tools that Komag adds to its production capacity under the terms of this
Agreement.
     (B) Komag understands and agrees that Maxtor’s intention is to fully
utilize MMC Capacity as a first priority, followed by fully utilizing Komag’s
Maxtor-dedicated capacity as a 2nd priority. Should market conditions force a
drastic downturn in demand, Maxtor may not be able to fully consume 100% of
Komag’s installed capacity.
     (C) Komag’s failure to deliver Product for any reason, including but not
limited to production problems, material shortages, quality issues and
qualification issues shall relieve Maxtor of any commitment to purchase Komag
Product for so long as such failure continues, plus reasonable times thereafter
for reallocation of commitments, at no penalty to Maxtor. Komag shall have a
cure period of thirty (30) days in which to cure any default in its volume
commitment to Maxtor. Notwithstanding the above, in the event of Komag’s failure
to deliver Product for any reason, Maxtor shall specifically have the right to
re-allocate material demand to other internal or external suppliers subject to
reasonable commitments required by said suppliers that may prevent Maxtor from
meeting its Product purchase commitments to Komag over a period ranging from the
balance of the quarter in which Komag fails to meet its supply commitment plus
the two quarters following that quarter, at no penalty to Maxtor. Maxtor shall
make every reasonable effort to minimize any such impact to Komag.
     (D) Maxtor’s volume forecasts and commitments are not fixed quantities, but
may vary with Maxtor’s level of business, tracking to Maxtor’s increasing or
decreasing HDD volumes and business projections, and such increases or decreases
shall be without penalty to Maxtor.
     (E) Any cancelled or rejected portion of an Order which is cancelled or
rejected because of Komag’s fault, including without limit warranty, inspection,
deliveries, shortages, or epidemic, shall be counted as purchased for the
purpose of determining Maxtor’s compliance with the foregoing volume purchase
commitment.
     (F) Maxtor’s commitment to purchase Product from Komag is strictly
predicated on:
          (i) Komag’s ability to qualify as required on multiple Maxtor drive
programs across all disk form factors offered by Maxtor, with disks capable of
supporting required drive performance using one Komag disk matched with all head
suppliers, or with one Komag disk matched to individual head suppliers, as
solely determined by Maxtor. Maxtor shall assign reasonable Engineering, SQE,
Factory and other resources to support Komag’s efforts to get qualified on
Maxtor products.
          (ii) Komag’s agreement that Maxtor’s volume commitments are contingent
upon Komag providing disks in a qualification time-frame that is equal to or
superior to Maxtor’s other supplier(s). Determination of the performance and
reliability aspects of the media provided by Komag shall be based on VCAP
yields, RTP yields, FGA results, SGT testing, HTS testing, the DPPM levels of
Maxtor drives, and any other tests and/or metrics which Maxtor may from time to
time implement or require. Any decision by Maxtor to purchase from an
alternative supplier, based on better performance in Maxtor’s drives, may, at
Maxtor’s sole option, be deducted from Maxtor’s percentage commitment to Komag
without penalty to Maxtor, based on at least one (1) month’s worth of data.
Notwithstanding the above, Komag’s performance will be assessed using at least
one (1) month’s work of drive data involving no less than 200,000 Komag disks.
Differences must be statistically significant.
          (iii) Komag’s agreement that if, after reasonable commercial efforts
by both parties, Komag fails to qualify on any Head-Disk combinations, then
Maxtor has no duty to purchase Product from Komag for such Head-Disk
combinations and Maxtor’s purchase requirements are reduced accordingly without
penalty to Maxtor.
          (iv) Komag agreement to provide disks to Maxtor with no degradation in
its ability to meet Maxtor’s glide and certification test specifications, as
defined for programs currently qualified and in production, or currently being
developed and/or tested and/or qualified by Maxtor. Any plans by Komag to change
any test parameters shall be submitted to and approved by Maxtor in Maxtor’s
sole discretion, prior to implementation by Komag. Should Komag be unable to
provide disks up to and including the anticipated volume of [****] disks per
quarter as the result of tester throughput issues and/or test parameters that do
not meet Maxtor’s specifications for quality or performance, Maxtor’s purchase
requirements are reduced accordingly without penalty to Maxtor.
          (v) Komag’s agreement that, in the event Komag fails to qualify with
each head for a particular Maxtor program on a timely basis, Maxtor may:
               (a) reduce Komag’s allocation for that program if Maxtor produces
HDD for

7

--------------------------------------------------------------------------------

 

the program with the head that Komag failed to qualify (and use reasonable
commercial efforts to award Komag compensating volumes in other Programs)
without penalty to Maxtor; and
                      (b) determine that the foregoing volume commitments shall
thereafter be measured without reference to such reduced program if Maxtor
produces HDD for the program with the head that Komag failed to qualify without
penalty to Maxtor.
          (G) In the event that Komag fails to qualify for any two (2) Maxtor
programs in a row, or for any three (3) Maxtor programs in any twelve (12) month
period, then Maxtor, in its sole discretion, may terminate this Agreement
without any penalty or payment whatsoever, and such termination shall not be a
breach of this Agreement.
2.3.2 Forecasts. During the term of this Agreement, Maxtor shall provide Komag,
on a monthly basis, with a four (4) quarter rolling forecast setting forth its
estimated Product needs and shall provide Orders for the first thirteen
(13) weeks of the forecast. Orders will be placed sixty (60) days in advance of
the date as of which the Products are to be delivered. Maxtor may request a
shorter lead time and Komag shall use its reasonable commercial efforts to meet
such date. Maxtor’s forecast is provided solely for Komag’s convenience and for
its planning purposes; no forecast shall be construed as an authorization by
Maxtor to order any materials for, or to allocate any labor or equipment for the
manufacture of the Product nor impose on Komag any obligation to supply
additional Product. Maxtor will not be responsible for any of Komag’s cost or
expense for materials, Product, labor, or other commitments or expenses, other
than as authorized in Orders.
2.3.3 Komag’s Capacity. Komag covenants to provide Maxtor with the right of
first refusal to fifty percent (50%) of any new, uncommitted capacity in order
to meet Maxtor’s Product needs.
2.3.4 Maxtor’s Forecast Allocation. Allocation of the forecast among Maxtor’s
programs is solely at Maxtor’s discretion and it is understood that Maxtor shall
have no duty under this Agreement to take or refrain from taking any action
which might, in Maxtor’s judgment, substantially and adversely impact Maxtor’s
relationships with or commitments to internal or external media vendors or
customers.
     (i) If Komag fails to meet the requirements for any Maxtor program at any
time, the Product quantities allocated for that Maxtor program within the
forecast may be reduced or eliminated by Maxtor. Maxtor will use reasonable
commercial efforts to award to Komag compensating increases in other Maxtor
programs.
     (ii) If Maxtor forecasts increased Product needs for any particular Maxtor
program, Maxtor will use reasonable commercial efforts to provide Komag with the
opportunity to supply increased quantities for such program, provided that Komag
is qualified to the configurations and customers driving the increased forecast
and is meeting Maxtor’s specifications and functional requirements, including
production ramp and yield. In such case, Maxtor will notify Komag of any such
resultant forecasted increased allocation and Komag will promptly notify Maxtor
of Komag’s available capacity and commitment to supply such increase.
     (iii) If Maxtor forecasts decreased Product needs for any particular Maxtor
program, Maxtor will use reasonable commercial efforts to award to Komag
compensating increases in other Maxtor programs, subject to the terms of
Section 2.3.1 (A).
     (iv) Should Maxtor not utilize Komag’s reserved capacity for a period
greater than ninety (90) days, and should Maxtor have no forecast to use said
capacity for an additional and successive ninety (90) days, then Komag may, with
Maxtor’s prior written agreement, utilize said capacity for a third (3rd) party,
subject to the terms and conditions following: (a) Komag may offer to and
utilize the capacity for any third (3rd) party only if such party agrees with
Komag in writing in advance to give up such capacity with thirty (30) days of
written notice by Komag; and (b) Komag can and will start production for Maxtor
for an existing qualified Maxtor product within forty-eight (48) hours of the
end of said thirty (30) day notice period, or such shorter period if the demand
requirements from the third (3rd) party should end in less than thirty
(30) days.
2.3.5 Shortages. With the exception of substrates, as set forth in Section 1.1.1
(iii), Komag agrees that in the event of a shortage of capacity or material that
will affect the supply of the Product, Maxtor’s Order(s), subject to normal
lead-time requirements, shall be filled according to an allocation plan at least
as favorable as those provided to all other Komag customers with similar or
lesser quantity forecasts and Orders. Komag shall provide Maxtor with as much
notice as possible if it anticipates or has reason to believe that Komag’s
output of the Product will not be sufficient to meet all of Maxtor’s Product
needs for any period.
2.4 Orders.
2.4.1 Orders. All purchases and sales shall be initiated by Maxtor’s issuance of
written purchase orders sent via airmail, E-mail, web-based, facsimile, or
courier (“Order”). Such Orders shall reference this Agreement and state the unit
quantities, unit descriptions, price, requested delivery dates and shipment
instructions. The

8

--------------------------------------------------------------------------------

 

acceptance by Komag of an Order shall be indicated by written or E-signature
acknowledgment within three (3) work days. Maxtor will have the right to deem
its order as accepted by Komag if Komag’s acknowledgment does not reach Maxtor
within ten (10) days from the date of the Order. By shipping the Products, or by
confirming or accepting an Order, or by performing the work described in an
Order, or by allowing an Order to be deemed accepted, Komag agrees to the Order
and to the terms and conditions of this Agreement. All Orders meeting the terms
and conditions of this Agreement shall be accepted by Komag.
2.4.2 Precedences. Any terms and conditions added or referenced by either party
in any purchase order, confirmation, acceptance or any similar document
purporting to modify the terms and conditions contained in this Agreement, shall
be disregarded unless expressly agreed upon in writing signed by the parties,
which expressly amends this Agreement. The preprinted terms and conditions of
purchase orders, acceptances, confirmations and similar business documents shall
have no effect as amendments of, objections to, or modifications of this
Agreement.
2.4.3 End of Life. Komag commits to supply Product to Maxtor for the duration of
the Maxtor HDD program for which the Product is qualified and until one
(1) calendar quarter after Maxtor’s last production build for the program. The
last purchase order date and the last shipment date for the Product for each
program shall be agreed to by the parties.
2.5 Inspection. Maxtor and Komag shall cooperate to inspect Products, and
nothing in this section shall limit Maxtor’s other rights and remedies.
2.5.1 Inspection by Maxtor. Maxtor may test each lot or Order of Product to
ensure that the Products meet Maxtor’s specifications and acceptance criteria,
and Komag shall not ship any Products that do not Conform. Product may be
inspected and tested by Maxtor or Maxtor’s agent at all reasonable times and
places after manufacture and before or after shipment. . If any inspection or
test is made on the Komag’s premises, Komag shall, without additional charge,
provide reasonable facilities and assistance for the safety and convenience of
inspectors in such manner as not unduly to delay the work. Inspection of
Products at Komag’s facility shall be without prejudice to Maxtor’s right to
inspect and reject such Products upon delivery to Maxtor’s facility. Where
applicable, Maxtor may, at its option, inspect all Products or inspect a
statistical sample selected from each lot, and Product, lots or Orders may be
inspected more than once. Product delivered to and inspected by Maxtor and
deemed acceptable by Maxtor will be transferred to Maxtor’s ownership and
invoiced according to terms set forth in this agreement.
2.5.2 Inspection by Komag. Komag will ensure that all Products are tested in
accordance with Maxtor’s specifications and requirements, as may be amended from
time to time. Komag will provide only those Products conforming to Maxtor’s
specifications and requirements, unless Komag has obtained prior written
approval from Maxtor for any deviation from such specifications. Komag further
agrees to maintain adequate authenticated inspection test documents that relate
to work performed under this Agreement. Such records shall be retained by Komag
for a period of two (2) years after Product shipment and made available to
Maxtor upon request. Komag agrees to supply Maxtor with inspection and test
reports, affidavits, certifications or any other documents as may be reasonably
requested. Komag agrees to collect and send to Maxtor, data on failure rates and
causes on a monthly basis in a mutually agreed format.
2.5.3 In Case of Failure of Inspection. If the above inspection or testing
detects Products which do not conform to the specifications or the requirements
of this Agreement, Maxtor and Komag will closely cooperate to identify and find
a way to correct the causes of the problem(s). Maxtor may refuse to accept
Product which does not conform. Maxtor may reject entire lots if lot acceptance
criteria established in the specifications are not fulfilled. The rejected
Product may, at Maxtor’s discretion, be returned to Komag and Komag may verify
the nonconformance. Maxtor will use its reasonable commercial efforts to assist
Komag in identifying and rectifying the cause(s) for rejection.
2.5.4 Stop Ship Order. Maxtor may stop future shipments of Product until the
cause(s) for non-conformity, as mutually determined by parties, have been
corrected. A stop ship order may be issued by Maxtor, without limiting its other
rights and remedies, when one half of one percent (.5%) or the threshold amount
stated in the Specification, whichever is less, of the Product shall be
non-conforming over a period of seven (7) days or more or over ten percent (10%)
of an Order or more, whichever occurs sooner. In the event Maxtor issues a stop
ship order, Komag must immediately cease shipment of the Products, and all
Orders which have been or would have been filled by the nonconforming Product
are terminated without liability to Maxtor until such stop ship order is lifted
and Maxtor retains all of its rights and remedies under this Agreement. Maxtor
will use commercially reasonable efforts to work with Komag to determine the
cause of the nonconformance problem and to develop solutions

--------------------------------------------------------------------------------

 

2.6 Shipping. The following terms apply to all shipments, whether Just In Time
(JIT) or otherwise.
2.6.1 Carrier. Komag and Maxtor shall agree upon the common carrier.
2.6.2 Timeliness. Komag shall use its best efforts to meet one hundred percent
(100%) on-time delivery commitments to Maxtor’s JIT HUBs, unless relieved of
such JIT HUB obligation in writing in advance by Maxtor. Notwithstanding the
above, Komag shall in all cases use its best efforts to ensure zero shortages to
any Maxtor production line. If Komag’s performance falls below one hundred
percent (100%) on-time deliveries, then Komag shall implement a corrective
action plan acceptable to Maxtor which brings the deliveries back to one hundred
percent (100%) on-time. If Komag is unable to deliver any Product on schedule,
Komag shall promptly notify Maxtor giving a new delivery date, and Maxtor may:
     (i) accept the new delivery date; or
     (ii) reschedule the delivery by means of a Change Order; or
     (iii) cancel the delayed portion of the Order without liability, if (i) and
(ii) above are not commercially reasonable for Maxtor.
At Maxtor’s request, Komag will provide Maxtor with daily notification of
shipping delays or of the progress of delayed Products in transit. Such
notification will include action plans to for recovery or expediting of the
affected Product.
2.6.3 Shipping Documents. Either invoice or delivery orders may be used when
making deliveries. Each set must contain three (3) copies. Each copy must
identify this Agreement, item number and description of Products, purchase order
number, and quantity of Products shipped. A complete packing list specifying
Maxtor’s applicable purchase order number, quantity of Products shipped, and
part number shall be enclosed with all shipments under this Agreement. All
documents accompanying the Products shall reference the purchase order number.
2.6.4 Packing. Unless otherwise specified in writing, all Products are to be
packed and marked in accordance with Maxtor’s specifications.
2.7 Just In Time (JIT) Delivery. Komag shall maintain a buffer stock of Products
in a quantity and location to be agreed upon from time to time in writing in
order to provide Just-In-Time (JIT) delivery to Maxtor. All expenses of
maintaining the buffer stock shall be borne and covered by Komag, including
without limit the expense of establishing EDI and/or E-mail links as required by
Maxtor, unless otherwise expressly provided by this Agreement. Maxtor recognizes
that Singapore law requires the payment of a tax on inventory that is held in a
JIT Hub more than thirty (30) days, and shall make reasonable efforts to pull
all such inventory within thirty (30) days, subject to drive build schedules. A
minimum of fourteen (14) days of buffer stock shall be maintained at the
warehouse; fourteen (14) days of buffer stock shall be determined as one half
(1/2) of the next four (4) weeks of Product on Order, unless the parties shall
agree to another level of buffer stock in writing. Such JIT buffer stock shall
be required at both Maxtor’s Singapore plants and Maxtor’s China plant. All
Products in the buffer stock shall have passed source inspection by Komag,
Maxtor, or both, before shipment to the warehouse. Maxtor will, from time to
time, typically daily, request deliveries from the buffer stock in quantities
that are even multiples of pallet loads by means of a pull signal.
2.8 Acceptance. If, after thirty (30) days from the date of receipt by Maxtor,
Maxtor has not rejected the Product, it will be deemed to have been accepted by
Maxtor. The act of inspection or payment by Maxtor for the Product will not be
construed as Maxtor’s acceptance of any Product. Acceptance of any Product shall
not affect the warranty or any remedy provided hereunder.
2.9 Returns. Returns of product to Komag are at Komag’s expense for shipping for
all returns which are caused by Komag’s fault and for reasonable and customary
packing in the event of significant returns which are caused by Komag’s fault,
including without limit warranty, inspection, and epidemics and are F.O.B.
Maxtor, and title and risk of loss pass to Komag upon delivery to the common
carrier at Maxtor’s dock. Komag shall pay all expenses for shipment of
replacement Product, which is caused by Komag’s fault, including without limit
warranty, inspection, and epidemics. Return shipments are F.O.B. Maxtor, and
title and risk of loss pass to Komag upon delivery to Maxtor’s dock. If Komag
requests, Maxtor will apply Komag’s Return Materials Authorization (RMA) or
similar number to the returned Products and/or related documentation, provided,
however, that Komag must supply such RMA number to Maxtor on a timely basis.
2.10 Epidemics. Epidemic or sweeping failures of Product may be detected
directly or by virtue of failures of Maxtor’s HDD’s, and the procedures and
remedies for epidemics are in addition to all other of Maxtor’s rights and
remedies available under this Agreement. An epidemic failure shall occur when
one percent (1%) of Maxtor’s HDD delivered to one or more

***CONFIDENTIAL TREATMENT HAS BEEN REQUESTED FOR PORTIONS OF THIS EXHIBIT. THE
COPY FILED HEREWITH OMITS THE INFORMATION SUBJECT TO THE CONFIDENTIALITY
REQUEST. OMISSIONS ARE DESIGNATED AS [****]. A COMPLETE VERSION OF THIS EXHIBIT
HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.
customers shall fail within six (6) months of delivery for reasons Maxtor
determines to be related to Product and which the parties have discussed. In the
event that Maxtor’s HDDs should develop any epidemic failure related to Komag’s
Product, the parties will meet in order to work out technical methods to
diagnose and remedy the problem. In such event, shipment of undelivered Products
related to the epidemic may be postponed, at Maxtor’s request, until the cause
of the epidemic has been corrected. In case upon the expiration of 30
(thirty) days from the date of Maxtor’s notice regarding the epidemic, Komag has
not yet remedied the same, then Maxtor shall be entitled to cancel pending
Orders without any liability for such cancellation and without prejudice to
Maxtor’s rights for damages or any other remedy. In the event that a remedy has
been found, all Product units subsequently delivered to Maxtor shall incorporate
the modification remedying the defect, if necessary, and Komag shall be obliged
to accept return of all Product units previously delivered to Maxtor, affected
by such epidemic, provided the epidemic is related to Product or Komag process
non-conformance. Maxtor agrees to re-accept delivery of such returned epidemic
material if it is mutually agreed that such epidemic failure has been remedied.
In the event Maxtor can show that the epidemic is due to the failure of the
Product to meet the Product Specification, Komag will refund the cost of the
Product and Maxtor and Komag will negotiate in good faith any direct expense
incurred for the rework of Maxtor’s HDD.
2.11 Invoicing. Komag will issue the invoices for the Products and will date
them with a date equal or subsequent to date of delivery to Maxtor’s dock.
Invoices shall reference this Agreement, purchase order number, item number and
description of Products, unit price of Products, and total amounts due.
2.12 Payment.
2.12.1 Terms. Invoices shall be due and payable:
      (i) [****] ;
      (ii) [****] ; and
      (iii) [****] .
2.12.2 Currency. Unless expressly provided to the contrary, all amounts stated
in this Agreement and all sums payable under this Agreement shall be denominated
in United States Dollars and all payments made under this Agreement shall be
made by wire transfer, cashier’s check, or other ready funds in United States
Dollars to payee’s designated account and bank.
2.12.3 Disputes. Maxtor shall have forty five (45) days after the invoice date
to contest in good faith the amounts and items charged. If the dispute is
resolved prior to fifteen (15) days before the original due date, payment shall
be due on the original due date. If the dispute is resolved thereafter, payment
is due fifteen (15) days after the resolution of the dispute.
2.13 Order Changes. No Order shall be deemed or construed to be modified,
amended, rescinded, canceled, or waived in whole or in part, except by a written
Change Order signed by a representative of each party.
2.13.1 Changes. Komag grants to Maxtor, subject to Komag’s plant constraints,
the right to make changes to the Product mix or schedule one or more times
without penalty, provided that the overall volume of the Order is not changed.
Komag must respond within two (2) working days. If any such change causes an
increase or decrease in the cost of, or the time required for performance of,
any part of the work on an Order or affects any other provisions, an equitable
adjustment shall be made in the price or delivery schedule, or both, and in such
other provisions as may be affected. It is understood that market conditions or
requirements by Maxtor’s customers may require changes in the Product mix one or
more times and it is anticipated that such changes may occur frequently. Any
claim by Komag for adjustment under this clause must be asserted in writing
within thirty (30) days of Komag’s receipt of the Change Order. Where the cost
of any property made obsolete or surplus as a result of a change is included in
Komag’s claim for such adjustment, Maxtor shall have the right to prescribe the
manner of disposition of such property once the claim payment has been made. If
Maxtor’s Change Order is an acceleration or increase, Komag will use its
reasonable commercial efforts to meet the requested quantities and/or delivery
dates.
2.13.2 Cancellation. Maxtor may cancel Order(s) by notifying Komag in writing.
Komag will cease work on

11

--------------------------------------------------------------------------------

 

the affected Order in accordance with such notice. Maxtor will
     (i) purchase and pay for any units of Product that have been completed as
of the effective date of the cancellation;
     (ii) will pay Komag the actual overhead, labor and materials costs incurred
by Komag in connection with the Production of any Products that are partially
completed as of the effective date of cancellation up to the total purchase
price under the canceled order(s);
     (iii) pay the costs of components and other materials procured by Komag
specifically on account of the canceled order(s), and receive title to such
items;
     (iv) pay the costs of components and other materials, including without
limit tools, dies, jigs, fixtures, plans, drawings, information and
manufacturing materials specifically produced or acquired for performance of
this Agreement and receive title to such items; and
     (v) pay any cancellation or restocking charges imposed by vendors on
account of any canceled orders pursuant to clauses (iii) and (iv) above.
Provided, however, that the aggregate of such payments shall not exceed the
amounts originally due under the Order. Komag will use its reasonable commercial
efforts to return components and other materials to its vendors and/or use them
in other activities at Komag. Komag will in any event use its reasonable
commercial efforts to mitigate the cancellation charges under this Agreement.
All Products which are purchased or paid for under the above terms shall count
as purchased for the purpose of determining total volumes of Product purchased
by Maxtor.
2.14 Engineering Changes. Komag shall not make any changes to the Product or any
process by which they are produced except as set forth in this section.
2.14.1 Definition. Engineering change(s) are those changes in Product design or
material according to the Specification or production process documented in the
mutually agreed Process Management Plan. Any Product which is subject to an
engineering change must be re-qualified unless otherwise provided by Maxtor in
writing.
2.14.2 Komag Change(s). Komag will notify Maxtor of any engineering change
proposed to be made by Komag to the Products or any process by which they are
produced, and will supply a written description of the expected effect of the
engineering change on the Products, including its effect on the form, fit,
function, schedule, price, performance, and reliability of the Products. Maxtor
may elect to evaluate the prototype, parts and/or designs specified as part of
the proposed change and Komag shall provide the prototype, parts and/or design
to Maxtor at applicable volume pricing for such evaluation. Maxtor agrees to
make every effort to approve or disapprove Komag’s proposed changes within five
(5) working days after receipt of Komag request for non-critical changes, and
within twenty-four (24) hours for critical changes. Komag will not change or
modify the Products or any process by which they are produced by implementation
of such engineering change without Maxtor’s prior written approval.
2.14.3 Maxtor Change(s). Maxtor may request, in writing and in a manner similar
to Komag’s request, that Komag incorporate any non-critical engineering change
into the Products, and Komag will provide to Maxtor its written response within
five (5) working days after receipt of Maxtor’s request Maxtor will give Komag
as much notice as possible of any expected request. For critical engineering
changes, as determined by Maxtor, Komag will respond within twenty-four
(24) hours of Maxtor’s written request. Komag’s response will state the cost
savings or increase, if any, expected to be created by the engineering change,
and the effect on the schedule and price of the Products. If Maxtor requests
Komag to incorporate an engineering change into the Products, the applicable
Specifications will be amended as required. Komag will not unreasonably refuse
to incorporate Maxtor’s engineering changes into the Products. In the event any
Maxtor required engineering change directly causes a negative financial impact
to Komag due to incorporation of such change into a Product, the parties agree
to promptly meet to discuss fair compensation for such financial impact. Komag
agrees to use its best efforts to notify Maxtor of such financial impact prior
to incorporation of such engineering change, and in any event, notify Maxtor as
soon as Komag becomes aware of such impact. Maxtor will determine whether the
Product must be re-qualified in whole or in part as a result of any engineering
change.
2.15 Working Relationship.
     (A) Designated Maxtor and Komag teams or team members will meet monthly or
as the parties may agree to review current and future plans and activities.
Agendas will include product and technology road-mapping, development and
qualification schedules, capacity planning, yield performance, cost targets,
volumes, plans, quality and delivery performance, and other topics related to
Maxtor and the Products.
     (B) Komag agrees to work collaboratively with Maxtor Advanced Development
teams on issues related to Komag’s new Product development and Maxtor’s hard
disk drive development.
     (C) The lead engineers of each party shall agree upon time tables,
contents, and procedures for Product and technology disclosures, at least
quarterly.
