1.1 Product.

1.1.1 Purchase and Supply. Maxtor wishes to secure a supply of Product and to purchase
quantities of such Product from Komag meeting Maxtor’s specifications set forth in Exhibit A and
for use in Maxtor’s HDD’s. Komag shall provide to Maxtor, exclusively, all of the capacity and
output from the Intevac Tools, Additive Tools, and Incremental Tools required to support this
Agreement. Komag wishes to supply such Product to Maxtor under the terms and conditions of this
Agreement and at the prices set forth on Exhibit B, as more completely detailed elsewhere in this
Agreement, including, but not limited to Section 1.4.1 Pricing. Therefore, subject to the terms
and conditions of this Agreement, Maxtor will purchase and Komag will supply Product for the term
of this Agreement. Maxtor’s obligation to purchase Product from Komag is contingent upon:

     (i) Komag’s Product meeting Maxtor’s requirements, including but not limited to time to
market, time to volume, Product specifications, performance, quality and functional requirements
(including, without limit, media-chargeable HDD yields), Maxtor customer requirements, and the
other terms and conditions of this Agreement.

     (ii) Komag’s commitment to Maxtor, on a best efforts basis, that the installation of the
Additive Tools shall be at least partially completed by the end of [****] , to a degree
sufficient to ensure that Komag can deliver to Maxtor the full quarterly capacity of at least
[****] . Komag’s commitment to capacity and production output on these [****]
machines shall take into account Maxtor’s normal qualification requirements for Products, tools,
and facilities.

     (iii) Komag’s commitment to provide the substrate input required for [****] Maxtor
disk output per quarter, taking into consideration the yields that are likely for the mix of
programs and form factors required from Maxtor. Komag shall meet its substrate commitments, either
by adjusting the allocation of its current internal and external substrate supply, or by adding
qualified capacity in its own or a third party facility.

1.1.2 Specifications. As of the Effective Date, Exhibit A may not be attached. The
parties will from time to time agree in writing upon specifications for the Product or amendments
to agreed-upon specifications and such agreed-upon specifications or amendments shall become parts
of Exhibit A and shall be incorporated into this Agreement when each such written agreement is
made.

1.1.3 Participation in Programs. Maxtor will use reasonable commercial efforts to qualify
and utilize Komag’s Product in all Maxtor programs as they are defined in Maxtor’s product roadmap.
Komag will use its best efforts to participate in all Maxtor programs as they are defined in
Maxtor’s product roadmap.

1.1.4 Freedom of Action. Nothing in this Agreement shall prevent either party from
engaging in similar business with other persons, including, without limit, competitors of the other
party, provided that the confidentiality and terms of this Agreement are not breached.

1.1.5 Second Sources. Komag understands that Maxtor qualifies additional sources for
Products or the same or substantially similar goods or materials from time to time and places its
orders among qualified internal and external suppliers as 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:

     (i) have a clear title, free of all security interests, encumbrances, or liens;

***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.

     (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 given, including
those set forth in this Agreement and Komag’s sales literature;

     (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

9

 

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

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.

12

 

     (D) Komag shall sample all new Product or other examples of development, including without limit
all new technologies, techniques, or processes, to Maxtor on a most favored basis.

the delayed party may defer any performance or delivery prevented by the force majeure condition

the contrary. References to quarter shall refer to Maxtor’s fiscal quarter unless expressly stated
