     6.0 Symbios Representations/Warranties

          6.1 Representations and Warranties:  Symbios represents and warrants:
     (i) it has the right to enter into this Agreement; (ii) Symbios'
     performance of this Agreement will not violate the terms of any license,
     contract agreement, note or other obligation to which Symbios is a party or
     any statute, law, regulation or ordinance to which Symbios is subject,
     including, without limitation, all health, safety and environmental
     statutes, laws, regulations and ordinances (iii) at the time of execution,
     no claim, lien, or action is pending or threatened against Symbios or its
     subsidiaries or parent company (and to the best of Symbios' knowledge after
     reasonable inquiry, Symbios' suppliers or affiliates) which would have a
     materially adverse impact on IBM's or its subsidiaries', or their
     respective distributors' or customers' use of the Products. Symbios will
     provide prompt written knowledge if subsequent action occurs; (iv) that, as
     of the date of this Agreement, the Product does not infringe any patent,
     trademark, copyright or other intellectual property right of a third party;
     (v) that (a) neither the Products contain nor are any of the Products
     manufactured using ozone depleting substances including, without
     limitation, chloroflurocarbons, halons, methyl chloroform and carbon
     tetrachloride; and (b) the Products do not contain any hazardous or
     carcinogenic materials or chemicals; (vi) each of the Products will not
     cause personal injury when used for its intended use; and (vii) all
     Products provided to IBM under this Agreement are new and do not contain
     anything used or reconditioned.

          6.2 Product Warranty:  Symbios warrants that from the date of shipment
     of the Product and for the period of time specified in the applicable PSPL,
     all Products provided to IBM are free from defects in material and
     workmanship, and will conform to all of the agreed upon specifications.

     This warranty does not apply to any Product which has been misused
(including static discharge, improper installation, repair, or accident),
neglected, or modified, or which Symbios is not capable of testing under those
test conditions that were used with the manufacturing and testing processes
during the original manufacturing of the Product. Supplier's sole obligation to
IBM for a Product failing to meet this Product warranty, and as mutually agreed
to by the parties, is to replace or repair the Product or to issue IBM a credit
for the purchase price of the Product, but only if (i) the failure has occurred
within the warranty period, (ii) Symbios has received written notice of the
warranty claim, (iii) IBM has returned the Product to Symbios under Symbios'
Return Material Authorization (RMA) procedure, and (iv) Symbios has reasonably
verified that the Product is defective. Symbios warrants a replacement or
repaired Product for the unexpired term of the warranty for the defective
Product, or for an extended warranty period as mutually agreed to by the
parties.

     THE WARRANTIES IN THIS AGREEMENT ARE IN LIEU OF ALL OTHER WARRANTS, EXPRESS
OR IMPLIED, INCLUDING THOSE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR USE.

     7.0 Intellectual Property Indemnification

     Symbios grants IBM all rights and licenses necessary for IBM and its
subsidiaries to use and sell the parts and commodities sold hereunder and to
exercise their rights under this Agreement. Symbios agrees to defend, at its
expense, and pay all damages, costs and attorney's fees finally awarded in any
claim that Symbios' Product infringes any intellectual property rights of a
third party or any claim that Symbios failed to comply with its representations
or warranties under Subsection 6.1 of this Agreement. If such a claim of
infringement is made, Symbios shall, use reasonable efforts to obtain for IBM
the right to continue to use and sell Symbios' Product or Symbios shall replace
it with non-infringing product which meets the Product specifications. If such a
claim of infringement is made before Symbios completes delivery of the affected
Product under this Agreement, Symbios may decline to make further shipments of
that Product without breaching this Agreement

     Supplier will not be obligated to defend or be liable for costs or damages
if the infringement solely and necessarily arises out of (a) IBM's technology or
compliance with IBM's written specifications, or (b) IBM's combining with,
adding to, or modifying the Product after shipment by Symbios, unless Symbios is
a contributory infringer, or (c) use of the Product, or any part of the Product,
in the practice of a manufacturing

                                        2

     control of the defaulting party, and the defaulting party shall provide the
     nondefaulting party immediate notice of any such anticipated delay or
     failure of compliance, provided, however, that the nondefaulting party
     shall be relieved of its obligations, except obligations to make payments
     for Products already provided, during the existence of such condition and
     that any such act shall relieve the defaulting party's obligations
     hereunder for such time as the conditions causing such delay or failure are

Exhibits and Product Unique Attachments ("Attachment"), is incorporated under
the Production Procurement Agreement [*], also referred to as [*] ("Agreement")
and is entered into by and between LSI Logic Storage Systems, Inc. ("LSI" or
"Supplier") and International Business Machines Corporation ("IBM", or "Buyer").
The original Agreement was entered into by Symbios Logic Inc. ("Symbios"), but
LSI has purchased Symbios in its entirety, and LSI hereby assumes all
obligations of Symbios and all terms and conditions of the Agreement as they
apply to this Attachment. This Attachment is conditional and does not become
binding unless and until the Closing Date, as defined in the Asset Purchase

     distribute on behalf of IBM only that quantity of Products that are ordered
     by IBM pursuant to a Work Authorization.

     2.0 Product Description

     The Products to be purchased under this Attachment are more fully described
in the Product Unique Attachments attached hereto.

     The Products are further described by the requirements set forth in the

          3.1 Tamper Evident Protection.  Each Product (except for spare parts
     as defined in Section 4.4) shall be required to have tamper evident
     protection to ensure that the Products are new when received by end user
     customers. Tamper evident protection will be in the form of IBM logo tape,
     labels or seals applied to the finished Product packaging in such a manner
     that if removed or tampered with, it would be evident that the finished
     Product packaging has been opened. Such tamper evident method must not be
     resealable, without evidence of tampering.

     LSI agrees to treat such IBM logo tape, labels, seals or other specified
materials with appropriate controls to prevent unauthorized use or dissemination
(including tracking the purchase, internal use, application, and destruction [to
avoid use by others]), and to limit access to such materials to only those with
a need to know to carry out the tamper evident sealing on new Products. LSI
agrees to only use the IBM logo tape, labels, seals or other specified materials
in connection with new Product, and not with any other product or with any Spare
Part.

          3.2 Labels.  LSI shall ensure that no markings, labels of any kind,
     are placed on the Products, other than as expressly specified by IBM in
     writing.

          3.3 Product Warranties:  Notwithstanding anything to the contrary, LSI
     represents and warrants that at all times: (i) for a period of [*] from
     Product delivery to IBM, the Product shall operate (a) in accordance with
     all specifications and requirements in this Attachment, and be free from
     defects in design, material, and workmanship, (b) in accordance with the
     uses as contemplated by the Agreement (including this Attachment),
     including those validated by completion of IBM's [*], and (c) in or with
     IBM product offerings. Those Products that do not conform to this or any
     other Product warranties shall,

     be repaired or replaced by LSI within [*] of IBM's notification to LSI.
     However, for situations involving non-conformance prior to IBM's delivery
     of its Product to IBM's customers and resellers, LSI shall replace the
     non-conforming Product with a new conforming Product within [*]. If repair
     or replacement is not reasonably feasible, then the purchase price paid
     shall be credited or refunded; (ii) for Products that either have: (a) Dead
     on Arrival (DOA performance is determined by dividing the number of defects
     by the number of systems installed by dealers and or customers) [*] of
     total Products purchased; (b) an epidemic defect rate of [*] of Products
     purchased with the same date code; (c) [*] of total Products purchased that
     contain defects related to the same root cause which has been determined
     and mutually agreed by both Parties; or (d) for Products that IBM has
     recalled or otherwise returned for safety reasons, LSI shall, at IBM's
     option within [*] of IBM's notification to LSI, repair and/or replace all

     repair or replacement is not reasonably feasible, then the purchase price
     paid shall be credited or refunded; (iii) LSI will maintain and submit to
     IBM, written evidence of the certifications and approvals addressed in this
     Attachment for all Products, and that LSI will affix all required labels
     regarding such certifications and approvals on the appropriate area of each
     Product and packaging; (iv) when used in accordance with its associated
     documentation, the Products purchased under this Attachment are Year 2000
     ready such that they are capable of correctly processing, providing,
     receiving and displaying date data, as well as exchanging accurate date
     data within and between the twentieth and twenty-first century, provided
     all other products (software, hardware and firmware) used with the Products
     properly exchange accurate date data with it.

     The warranties in this Subsection 3.3 shall be considered to be part of the
warranties in Subsection 6.1 of the Agreement and supplement any other
warranties in Section 6.0 of the Agreement.

          3.4 Product Support Training and Documentation.  LSI shall provide
     with reasonable frequency "T3" training (i.e., teaching individuals in a
     manner to allow them to teach others) which shall be conducted at Research
     Triangle Park, NC. IBM shall provide reasonable travel and living expenses
     for this training. Education materials for "T3" training will be provided
     by LSI in reasonable quantities. Education updates would also be required
     for significant changes in the product or in the repair or support of the
     Product for which IBM will provide reasonable training, travel and living
     expenses.

          3.5 Product Field Support.  IBM customer support may include providing
     end-user customer support by telephone or electronic methods ("Level 1
     Support") and determining whether any defects, quality issues or other
     problems exist with the Product and provide a solution within [*] from
     end-user customer's inquiry ("Level 2 Support"). LSI shall be responsible
     to provide appropriate training and diagnostic tools so that IBM may
     provide such Level 1 and Level 2 Support. LSI shall provide Level 3 Support
     (support inquiries from IBM that exceed the capabilities of Level 2
     Support) and will provide a solution to such problems within [*] from IBM's
     inquiry. LSI shall provide IBM an LSI engineering contact name and phone
     number for Level 3 Support purposes. For problems that the parties mutually
     agree are more complex, the parties shall use best efforts to finalize a
     plan and provide a solution within [*] from IBM's inquiry.

     In the event repairs or corrections to the Products are required, LSI shall
make and test the necessary repairs or corrections, and LSI shall include such
repairs or corrections in subsequently delivered Product. LSI shall maintain a
comprehensive log of all Level 3 defects, repairs, and corrections, and shall
ensure that IBM has the most current version of such log to properly assist
customers. Within [*] of preparing repairs or corrections. LSI shall deliver to
IBM updated technical specifications and Product documentation reflecting such
corrections or repairs. The Product support described in this Attachment shall
not relieve LSI from any warranty obligations.

     IBM has the right to withhold payments in any amount equivalent to the
price of all Products affected by the Severity Level 1 defect (e.g., the
customer is unable to use the product and/or customer operations are critically
impacted) due to LSI upon notice to LSI of a Severity Level 1 (SL1) Defect,
until such Defect is corrected to IBM's reasonable satisfaction. An SL1 Defect
is a defect that results in an emergency condition that causes critical impact
to IBM's schedule or that critically hinders performance or continued
performance of the Product.

     Product (Hereinafter, these materials and assistance shall be referred to
     as the "Manufacturing Package"), upon the occurrence of any of the
     following from which LSI and IBM reasonably believes LSI cannot recover:
     (a) commencement of any involuntary proceeding in bankruptcy or insolvency
     against LSI; or (b) appointment, without LSI's consent, of a receiver or an
     assignee for the benefit of creditors; or (c) LSI ceases to carry on
     business as an on-going entity; or (d) LSI, for any other reason, does not
     meet the on time delivery criteria defined in Section 8.3 of this PSPL and
     does not expect to again provide or is unable to again provide on time
     delivery; or (e) LSI materially breaches the Agreement (including this
     Attachment). LSI shall provide the Manufacturing Package as soon as
     possible after IBM requests it, but in no event more than [*] following

     Subsection, and except in cases where tooling or modifications to tooling
     are requested by IBM, LSI shall, [*], supply and do all things necessary,
     including, without limitation, supply all tooling and equipment required
     for the manufacture and testing of the Product. In the event that IBM has
     paid for, or otherwise snakes available to LSI, tooling or equipment
     pertaining to any aspect of the Product, LSI agrees to sign a separate
     tooling loan agreement that addresses additional loan requirements.

          3.11 Product Cost Reduction Enhancements.  If LSI decides to market a
     product that is positioned as a cost reduced or enhanced version of the
     Products, LSI agrees to offer and sell said product as "Product" to IBM
     under the terms and conditions of this Attachment, except for price that
     will be negotiated between the parties. If IBM buys said replacement
     product, the quantity purchased in combination with the quantity of the
     original Products purchased hereunder, shall collectively apply to IBM's
     purchase quantities for purposes of calculating price, to the extent that
     Product pricing is determined by quantities purchased. Notwithstanding the
     above, unless the parties agree in a written amendment that a particular
     enhanced product shall replace the "Product," LSI agrees to continue to
     make the original Product available to IBM through the end of Product's
     life.

          3.12 Compatibility Requirements.  The Product shall meet its
     functional specifications. LSI will work with IBM to make the Product

                                        4
<PAGE>

     expressed in Work Authorizations ("WAs," i.e., written or electronic IBM
     purchase orders or other electronic transactions that are expressly
     identified by IBM as an authorization to perform work under the Agreement,
     including this Attachment) shall be the only charges due to LSI from IBM,
     unless otherwise authorized in writing by IBM. LSI warrants that the
     pricing in the Product Unique Attachments does not include sales taxes and
     that LSI will not include, or otherwise charge IBM for, any sales tax on
     any Products purchased by IBM. IBM will provide LSI with an applicable sale
     tax exemption certificate, as appropriate.

          4.2 Cost Reductions.  LSI agrees to provide IBM cost reductions
     consistent with industry pricing and technology trends.

          4.3 Payments.  LSI will invoice IBM upon shipment of Product to IBM.
     Terms for payment on all invoices will be net [*] from date of acceptable
     invoice to IBM. Payment of invoices shall not be deemed acceptance of the
     Products. All prices are expressed in US dollars.

          4.4 Spare Parts and Field Replacement Units (FRUs).  The list of FRUs
     (also referred to as spare parts, which may consist of the entire Product
     or portions thereof) and agreed to pricing for FRUs (for cases where IBM
     elects to purchase FRUs) shall be listed in the relevant Product Unique
     Attachment, provided, however, that the parties may elect to establish
     updated pricing for such FRUs via other documents that are signed by both
     parties. IBM reserves the right to review LSI's FRUs supply plan. Should
     IBM purchase FRUs for the Product from LSI, LSI shall not be relieved from
     any of its warranty and support obligations. LSI shall reimburse IBM for
     any FRUs IBM has to replace due to LSI's failure to comply with any of its
     warranties and representations.

     FRUs will be made available for [*], or longer if legally required by law
after: (a) the expiration of this Attachment; (b) the last shipment of Product
from LSI; or (c) IBM's withdrawal of the Product from the market, whichever
occurs last, unless otherwise expressly agreed upon in writing for longer
periods by both parties for the applicable Product.

     For the Products under this Attachment, LSI will not substitute FRUs, even
if such FRUs are equal or better to those originally approved by IBM, unless
expressly agreed to by IBM in writing.

     LSI shall ship FRUs for returned parts within [*] of receipt. All FRUs
shall be upgraded to the latest EC level, single-packed and single-labeled.

     For the purposes of evaluating LSI's performance, as it relates to FRU
orders, LSI will be measured against the following criteria. LSI scores are
calculated on a monthly basis and are used to compare LSI to other similarly
situated suppliers and the awarding of business. Nothing in this section shall
relieve Supplier of any obligations in the Agreement (including this
Attachment).

     In any calendar month in which LSI fails to meet the above performance
criteria specified in this section, LSI will respond to IBM with an agreed upon
action plan within [*] of notification by IBM demonstrating its ability to
achieve the required measurements. LSI's failure to successfully execute an
action plan within an agreed upon time frame, may, in addition to other remedies
in the Agreement (including this Attachment) and at law, result in substantial
or complete reduction of new business awards from IBM.

     IBM will obtain RMA (Returned Material Authorization) from LSI prior to
shipment of returned FRUs, subject to LSI promptly providing such RMA to IBM
upon request. LSI will acknowledge receipt of

                                        5
<PAGE>

FRUs within [*] of receipt, and such acknowledgment shall include a report
regarding any shortages, overages or damages alleged to have occurred in
transit. LSI will reimburse IBM at the current FRU price for FRUs that are
stripped, stolen, lost, damaged or unaccounted for, except for those reported to
IBM upon initial receipt of the returned FRUs.

     LSI will provide a packing slip with all return shipments of unrepairable
FRUs to IBM which specify LSI's name, IBM part numbers being shipped, quantity
of each part number being shipped, and the relevant Purchase Order number. In
addition to the above, the packing slip for FRU returns which are unrepairable
will also reference a return authorization number (such numbers are obtained by
contacting IBM), provide a reason for return, and will be shipped within [*]
after receiving IBM's authorization.

     5.0 Work Authorization Logistics

          5.1 Placement of Work Authorizations (WA's), Reschedules and
     Cancellations.  WAs, duly issued by IBM procurement personnel, shall be the
     only authorization for LSI to deliver any Product under this Attachment.
     IBM shall have no obligation to issue any Work Authorizations. IBM shall
     not be liable for any costs incurred by LSI in its anticipation of
     receiving Work Authorizations or in performing work in excess of any
     authorized limits of Work Authorizations issued hereunder. Except as
     expressly stated in this Subsection 5.1 and as authorized under Work
     Authorizations, all other expenses in support of this Attachment shall be
     borne by LSI, without liability to IBM, unless authorized by IBM in
     writing.

     IBM's Product order lead time from WA issuance to delivery is [*]. LSI
agrees to cooperate and use all reasonable efforts for cases where IBM requests
an earlier delivery. Any increase in the agreed to lead-time must have IBM's
prior written approval.

     IBM MAY USE "BLANKET" PURCHASE ORDERS (e.g., electronically these may
identified as "Scheduling Agreements") WHICH MAY HAVE THE APPEARANCE OF A NORMAL
PURCHASE ORDER, BUT SUCH BLANKET PURCHASE ORDERS CAN BE DISTINGUISHED BY NOT
HAVING A DELIVERY DATE AND ARE ISSUED ONLY AS A LOGISTICAL PROCESSING DOCUMENT
TO ENABLE THE USE OF ELECTRONIC PURCHASE ORDER COMMUNICATIONS AND ARE NOT
BINDING IN ANY MANNER AND SHALL NOT BE INTERPRETED AS AN AUTHORIZATION TO
PERFORM ANY WORK, REGARDLESS OF ANY QUANTITIES OR PRICES THAT MAY BE INCLUDED IN
SUCH BLANKET PURCHASE ORDERS.

             5.1.1 Accommodation of Increases in Order Volume.  LSI agrees to
        use all reasonable efforts to accommodate the following increases to
        Product order quantities which may be made by IBM without any additional

     Authorizations issued by IBM provided such Work Authorizations comply with
     the terms and conditions of this Attachment. LSI shall confirm receipt of
     each Work Authorization and, if LSI does not object to such Work
     Authorization within [*] of receipt and identify the reasons of
     non-compliance with this Attachment, then such Work Authorization will be
     deemed to have been accepted by LSI.

                                        7
<PAGE>

     IBM may provide [*] estimated forecast for any quantities of Product that
may be required. LSI will use reasonable efforts to respond to such forecast
within [*].

     ANY PRODUCT QUANTITIES CITED IN OR IN SUPPORT OF THIS AGREEMENT (INCLUDING
THIS ATTACHMENT) ARE PRELIMINARY ONLY AND SHALL NOT IN ANY WAY BE CONSTRUED AS A
COMMITMENT AND ARE NON-BINDING. IBM MAKES NO REPRESENTATION OR WARRANTY AS TO
THE QUANTITY OF PRODUCTS THAT IT WILL PURCHASE, IF ANY.

          5.3 Product Allocation.  LSI will ensure proper management and
     operational controls are present to provide for an equitable and
     proportional allocation of capacity, resources, commodities, tooling and
     any other items required to execute this Attachment. In the event of a
     non-LSI controlled shortage of any items necessary to satisfy the
     requirements of LSI internal (i.e., LSI branded products) and external
     customers, the order of precedence for said allocation will be; (i) the
     acknowledged purchase orders, (ii) pending purchase orders, and (iii)
     system forecasts from all affected parties submitted and on record for the
     month in which the shortage became known to LSI. [*]. Non-LSI-controlled
     shortages are those events that occur in the industry at-large. Shortages
     caused by LSI actions (e.g. commodity purchase orders not placed, internal
     or external LSI customer demand increase which LSI accepts) will not
     relieve LSI of its obligation to meet IBM's accepted Work Authorizations
     and will use reasonable efforts to meet forecasted demands, including the
     associated flexibility terms set forth in this Attachment.

     LSI will promptly notify IBM in writing that such a shortage has occurred,
the expected duration of said shortage, and the impact upon the monthly forecast
in use at that time. LSI will include in this notification that IBM is receiving
its proportional share of all LSI resources and that no LSI internal or external
customer has received preferential treatment in the allocation of resources.

     Notwithstanding the above, (a) IBM shall have first priority to all
components, subassemblies or services supplied by suppliers that IBM has
directed to or otherwise presented to LSI provided they are deemed acceptable by
LSI and such suppliers are not current suppliers to LSI; or such suppliers may
be current suppliers to LSI provided the supplies provided by suppliers are
those that have been previously allocated to IBM over and above those supplies
previously allocated to LSI; (b) any IBM or IBM subsidiary supplied components,
subassemblies or services shall only be used on Products hereunder, unless
otherwise agreed to in writing by the parties, and (c) LSI will use reasonable
efforts to mitigate the impact to IBM of all shortages, regardless of their
nature or cause.

     6.0 Product Replacements

     IBM and LSI will jointly establish a process to replace Products for
situations identified by IBM that are essential for IBM to maintain a positive
relationship with its customer and are not related to any Product defects or
warranty claims. IBM will identify the Products to LSI in writing, and LSI will
use reasonable efforts to provide such replacement Products within [*] if
Product is in LSI's inventory or otherwise within [*] to customers, at IBM's
cost, subject to the parties prior written agreement of such cost.

     7.0 Quality, Inspection and Acceptance

          7.1 Quality Plan.  LSI shall implement and maintain a comprehensive
     quality plan (including inspection and quality assurance procedures) that
     demonstrates a high quality Product rate and continuous quality improvement
     of the Product production. LSI will provide monthly Product reports to IBM.
     Such quality plan shall be submitted to IBM for review and approval. Once
     approved, such document shall be incorporated herein by reference.

          7.2 On-Site Product Inspections.  LSI's responsibilities hereunder
     shall include comprehensive quality controls, testing and inspection of the
     Products and all components and subassemblies thereof IBM may also inspect
     the Products at LSI facilities with reasonable advance notice and perform
     additional inspection and testing of all Products delivered to customers,
     and may refuse to accept Products that do not conform to all
     specifications, warranties, and/or other requirements.

                                        8
<PAGE>

          7.3 Use of NDF Products.  "No-Defects-Found Product" ("NDF-Product")
     shall mean any Product that has been returned to LSI as defective, but
     after comprehensive analysis and testing, the Product was found by the
     parties not to be defective in any manner. LSI agrees that NDF Products
     shall not be used in any Products, except in spare parts. LSI further
     agrees that any NDF Product that has been used in a Spare Part, and then
     subsequently returned and found to be an NDF Product again, will never be
     used hereunder, even as a Spare Part.

     However, LSI may use such returned Spare Part for LSI's own independent
purposes outside of this Attachment, subject to: (a) LSI removing all references
to IBM (including, but not limited to logos, labels, model numbers, etc.,
regardless of whether such references are in the hardware or code) and all IBM
unique features (e.g. bezels, documentation, or other ship group material). LSI
hereby agrees to protect, defend, hold harmless and indemnify IBM and customers
from and against any and all claims, suits, actions, demands or liabilities
arising out of LSI's use of such returned spare parts outside of this Agreement.

     8.0 Delivery

          8.1 Product Delivery.  All Products and spare parts may be shipped FOB
     receipt by carriers from the replenishment centers as designated by IBM.
     Payment of transportation, import/export fees, duties, taxes and tariffs
     will be specified in the relevant Product Unique Attachment or in another
     document signed by IBM and LSI. LSI shall utilize the "pull process"
     through EDI allowing IBM to systematically request Product from LSI on an
     as needed basis. At the request of IBM, LSI shall work with IBM to jointly
     establish a written process for handling missing items from the original
     ship groups.

          8.3 On-Time Delivery.  If LSI cannot meet a scheduled delivery date,
     LSI shall promptly notify IBM of LSI's revised delivery date and IBM may,
     at its option, (i) reschedule Products, (ii) [*] associated with shipping
     and handling incurred as a result of the late delivery, (iii) cancel
     Products not delivered without charge; and (iv) exercise all other remedies
     provided at law, in equity and in the Agreement, including this Attachment.

     Notwithstanding anything to the contrary contained in the Agreement or this
Attachment, if LSI fails to deliver products on time and to the extent that such
failure is caused solely by: (a) LSI's inability to utilize (for reasons beyond
LSI's reasonable control) any of the Assigned Information, Assigned Copyrights,
Assigned Software, and/or licensed materials (as such capitalized terms are
defined in that certain Intellectual Property Agreement between IBM and LSI
dated June 28, 2002) or (b) IBM's default under any agreement between IBM and
LSI executed in connection with LSI's acquisition of the assets set forth in the
Asset Purchase Agreement between IBM and LSI dated June 28, 2002, then the
failure to deliver products on time shall not be considered a breech of this
Attachment and LSI will not be responsible for the [*] set forth above as long
as LSI uses commercially reasonable efforts to mitigate the effects of the delay
and otherwise complies with IBM instructions regarding the Product.

          8.4 Date of Manufacture.  LSI agrees that the date of manufacture for
     all Products purchased by IBM shall be less than [*] from the date of
     Product delivery to the IBM designated replenishment warehouse.

          8.5 Distribution of [*] Software.  Pursuant to Section 3.1.13.3 of the
     IBM/[*] agreement [*], LSI will be provided with the [*] software Version
     2.0 and updates thereto ("[*] Software") on shrink wrap CDs and shall have
     the right to include the [*] Software within the Product carton and
     distribute the same with the Product. LSI will have no right to modify the
     [*] Software or distribute it in a manner other than as described herein
     and shall not remove or tamper with the tamper evident protection provided
     with the [*] Software. IBM represents that LSI's performance pursuant to
     the terms of this Section 8.5 will not violate the terms of SOW [*]. IBM
     may terminate this Section 8.5 at any time by providing LSI a written
     termination notice.

     9.0 Replenishment

          9.1 Replenishment Logistics

     This section 9.0 shall only apply when Pull Profiles are addressed as
described below.

          9.2 Pull Definitions

     "Pull Buffer" means a quantity of Pull Products within the Liability
Horizon Quantity which is held in inventory by Supplier.

     "Pull Products" means Products specified in a Pull Product Profile.

     "Pull Product Profile," "Pull Profile," "MIRS Profile," or "Profile" means
the relevant document signed by both parties or otherwise included in a PSPL
describing the Pull Products and supporting information, including, but not
limited to, IBM Part Number, Liability Horizon, Replenishment Time and packaging
requirements.

     "Pull Purchase Order," "Pro forma Purchase Order," "PPO," or "Purchase
Order" means a purchase order used by Buyer as a logistical tool only to enable
system and related activities for the pull process, and does not represent a
firm offer by Buyer nor bind Buyer to any quantity or delivery date.

     "Liability Horizon" means the period of time as specified in the relevant
Pull Profile used to calculate the maximum liability for a given Pull Product,
by applying the Liability Horizon period against the Planning Schedule.

     "Liability Horizon Quantity" means the quantity of Pull Products specified
in the Planning Schedule contained within the Liability Horizon. The Liability
Horizon Quantity is the WA for Pull Products ordered under this section 9.0.

     "Upside Flexibility" means a percentage of Pull Products specified in the
Pull Profile in excess of the Liability Horizon Quantity.

     "Liability Horizon Quantity Overage" or "Overage Limit" or "Overage" means
a Liability Horizon Quantity which exceeds the quantity of Pull Products
committed to in the Pull Notifications for the same period.

     "Planning Schedule" means Buyer's [*] of requirements for Pull Products.

     "Pull Notification" means Buyer's only authorization for Supplier to
deliver a specified quantity of Pull Products. "Replenishment Time" means the
total elapsed time from Supplier receipt of a Pull Notification to delivery of
the Pull Products to Buyer's location as specified in this PSPL or Pull Profile.
The Replenishment Time consist of response time, transit time and/or process
time as defined in the relevant Pull Profile.

          9.3 Pull Profile Planning

     After the parties agree to a Pull Profile, Buyer may issue a PPO to
Supplier for all Pull Products. Buyer may issue a Planning Schedule at intervals
as specified in the Pull Profile, the most recent Planning Schedule to supersede
all previous Planning Schedules. The Planning Schedule provides a forecast of
requirements for the Pull Products and establishes quantities applicable to the
Liability Horizon Quantity and Upside Flexibility, if any, with the Supplier.
Supplier will respond to the Planning Schedule as specified in this PSPL or Pull
Profile.

          9.4 Pull Delivery

     Supplier will deliver to Buyer on the delivery date the Pull Products
specified in the Pull Notifications issued by Buyer, provided such Pull
Notifications do not exceed the Liability Horizon Quantity. Supplier will comply
with Pull Notifications for quantities of Pull Products in excess of the
Liability Horizon Quantity but within the Upside Flexibility. Risk of loss and
title will pass to Buyer when Product is pulled from consignment.

                                        10
<PAGE>

          9.5 Pull Limitation of Liability

     Unless the Pull Products are specified in a Planning Schedule in
conjunction with the Liability Horizon in a Pull Profile, Buyer makes no
representation or warranty and assumes no liability regarding the quantity of
Pull Products that it will purchase. Buyer assumes no liability for materials
procured or products built beyond the Liability Horizon Quantity. Supplier will
apply Overages towards future Pull Notifications and the parties will agree to a
reconciliation amount and a disposition of Overage Products, if any. The
reconciliation amount will be reduced by any amount realized by Supplier for
Pull Products (including raw materials or works-in-progress) used, returned or
sold to any party, and any other reductions agreed to by the parties.

          9.6 Order of Precedence

     Notwithstanding section 9.11 of the Agreement (i.e. [*]), in the event of
any conflict in the documents contained in the Agreement involving Pull
Products, the order of precedence will be: (i) the Pull Profile in section 9.7
below (or separate Pull Profile if signed separate from but in support of this
Attachment); (ii) this section 9.0; (iii) the relevant Product Unique
Attachment, (iv) the balance of this Attachment; and (v) the Agreement (i.e.
[*]).

warehouse.

     (2) Parties shall use commercially reasonable efforts to reconcile
inventory and any associated liabilities monthly;

     (3) The Parties agree to periodically review the status of inventory in the
warehouse. Based on the periodic review, the parties shall engage in
commercially reasonable actions to mitigate inventory exposure. When warehouse
inventory exceeds the required buffer stock in Section 9.7 (Pull Product
Profile), IBM agrees to pull Product that has been in the warehouse for [*]
provided it is a business day (otherwise on the next business day), unless the
parties agree to some other commercially reasonable period.

     (4) Beginning [*] prior to the [*]and on a [*] basis thereafter, LSI and
IBM will work together and use commercially reasonable efforts to precisely
determine the inventory quantity in the warehouse at the end of the [*].

     10.0 Engineering Record Changes

     LSI will notify IBM before any LSI initiated changes, which shall not take
place without IBM approval. LSI will advise IBM promptly in writing of any LSI
initiated changes that will affect the form, fit or function of the Product, and
will ensure that such changes do not compromise the quality, reliability,
compatibility or performance of Products ordered by IBM hereunder. LSI will not
implement any form, fit or function changes to the Product without IBM's prior
written approval.

     IBM may request changes to the Product in writing at any time. LSI will
promptly consider such changes and inform IBM in writing of the affect of
suggested changes on form, fit or function, price and schedule. The parties will
negotiate in good faith to resolve any adjustments in price, schedule and/or
specifications prior to implementation.

     party or in the event that the other party becomes insolvent, files, or has
     filed against it, a petition in bankruptcy or undergoes a reorganization
     pursuant to a petition in bankruptcy. Such termination shall become
     effective [*] after receipt of such notice, unless the party receiving
     notice remedies the cause cited in such notice within such [*] period. In
     the event LSI terminates an Attachment as set forth in this Subsection
     12.1, LSI shall have the right to cancel all outstanding WAs. In the event
     IBM terminates an Attachment as set forth in this Subsection 12.1, LSI
     shall immediately (a) cease all work and shall treat all applicable
     outstanding WAs in accordance with Subsection 12.2, (b) prepare and submit
     to IBM an itemization of all completed and partially completed Products
     under such WAs, and at IBM's sole option and only upon IBM's written
     direction, LSI shall deliver to IBM the (i) number of IBM requested
     completed Products at the prices set forth in the applicable WA and (ii)
     IBM requested partially completed Products at a price not to exceed the
     actual and reasonable costs substantiated by LSI within any authorized
     limits and cancellation schedules set forth in this Attachment and WAs,
     provided however, in no event shall such price exceed the per unit price of
     the Product, (c) allow IBM access to LSI's premises to take possession of
     all IBM owned property or to file a security interest in such property, and
     (d) return to IBM all IBM confidential information or property, if any. IBM

     the notice. LSI will immediately cease all work under such WA in accordance
     with the cancellation notice. IBM shall have no liability if it cancels WAs
     for reasonable cause.

     Any existing credits in IBM's favor at the time of cancellation shall be
deducted from any amount due to LSI and if such credits exceed the amount due to
LSI under the applicable WA, LSI agrees to refund the difference to IBM within
[*] of the effective date of cancellation. The results of all work paid for by
IBM under the applicable WA are the sole property of IBM, and upon cancellation,
the disposition of all such IBM property shall be in accordance with IBM's
written instructions.

          12.3 Attachment Termination for Convenience.  IBM may terminate this
     Attachment for convenience at any time by providing LSI written termination
     notice, and such notice shall be effective immediately upon LSI's receipt
     of such notice, unless the notice provides for a longer period. In the
     event of such notice, LSI shall immediately cease all work and shall treat
     all applicable outstanding WAs in accordance with Subsection 5.1.2, from
     the time of receipt of the written termination notice. IBM's total and
     maximum liability is set forth in Subsection 5.1.2.

     logos at all times in accordance with the specifications in this
     Attachment.

     16.0 Freedom of Action

     Nothing in this Attachment shall be construed as: (a) prohibiting or
restricting either party or their subsidiaries from independently developing,
having developed independently, acquiring, licensing, distributing or marketing
products, services and other materials which are competitive in any form with
the Products; or (b) affecting either party's pricing of products or services,
other than LSI's pricing of Products and services to IBM hereunder. Nothing in

     17.0 Intellectual Property

          17.1 Confidential Information.  All confidential information exchanged
     between the parties shall be exchanged under and governed by the terms and
     conditions of Confidential Disclosure Agreement [*]. LSI agrees not to
     disclose any information concerning the Product hereunder, or any
     supporting activity thereof, without IBM's prior written permission, except
     as may be required by law or governmental rule or regulation, or to
     establish LSI's rights under this Attachment; provided, however, that if
     LSI seeks to disclose for reasons not requiring IBM's prior written
     approval, LSI shall limit such disclosure to the extent required, shall
     allow IBM to review the information disclosed prior to the disclosure, and
     shall apply, where available, for confidentiality protective orders and the
     like. Any such review by IBM shall not be construed to make IBM responsible
     for the contents of the disclosure, and LSI remains solely liable for the
     contents thereof. Except as stated above in this Subsection 17.1 and in any
     separately signed agreement for the exchange of confidential information,
     neither party shall have any obligation of confidentiality to the other.

          17.2 Trademarks.  Notwithstanding any other provisions of this
     Attachment to the contrary, neither party shall have the right to use the
     trademarks, service marks, trade names, or product names of

     21.0 Conditional Obligation to Purchase Products

          21.1 Subject to the limitations and exclusions provided in this SOW,
     LSI agrees to sell to IBM and IBM agrees to purchase from LSI the portions
     of IBM's (a) [*]and (b) [*] for new [*] and [*] enclosures [*] as expressly
     identified in Product-Unique Attachments #1 and #2 attached hereto, for the
     following time periods:

             (a) From the Effective Date of this Attachment through the [*] of
        the Effective Date, IBM will purchase [*] of the [*] and [*] of SSG's
        [*] during this time period; and

             (b) From the [*] of the Effective Date plus [*] of the Effective
        Date, IBM will purchase no less than [*] of the [*] brand's and no less
        than [*] of SSG's [*] during this period.

          21.2 "[*]" means the number of units the [*] or SSG, as applicable,
     requires to fulfill customer orders received by IBM for the Products
     worldwide during the time periods set forth immediately above, subject to
     the limitations and exclusions provided in this Attachment. IBM makes no
     representations or commitments regarding the amount of its [*] or the
     number of Products it will order. IBM is under no obligation to purchase
     Products in any quantity.

          21.3 Notwithstanding the foregoing, IBM is relieved of its conditional
     obligation to purchase its [*] for Products hereunder and shall have no
     liability to LSI to the extent that:

             (1) LSI does not produce Products that conform to specifications or
        other requirements of the Agreement and does not remedy that situation
        in accordance with the terms of any relevant Product Unique Attachment,
        this Attachment, or the Agreement;

             (2) IBM cancels WAs due to LSI's failure to deliver Products on
        time as per Section 8.3 of this Attachment;(3) IBM cancels WAs for cause
        as per Section 12.2 of this Attachment;

             (4) LSI does not remain competitive as required under Section 22 of
        this Attachment;

             (5) LSI otherwise fails to comply with a material term of this
        Attachment (including the Product Unique Attachments) or the Agreement
        and fails to cure such noncompliance in accordance with this Attachment
        or the Agreement;

                                        15
<PAGE>

             (6) LSI has actual knowledge of situation(s) where IBM has not
        complied with this Section 21.0 and LSI fails to notify IBM where such
        notice could have enabled IBM to cure without subsequent liability to
        LSI;

             (7) LSI declines to bid in response to a IBM RFQ or fails to
        fulfill a WA;

             (8) either party terminates all or part of this Attachment or the
        Agreement in accordance with the terms of Section 12 of this Attachment;

             (9) a Competitor of IBM acquires a beneficial interest in at least
        [*] of the outstanding shares, securities, or ownership interests
        representing the right to vote for the election of managing authority or
        the right to make decisions for LSI; or if a Competitor of IBM
        purchases, leases, licenses or otherwise acquires a beneficial interest
        in at least [*] of the assets of LSI; or if a Competitor of IBM becomes
        entitled to appoint a [*]; or if work performed by LSI for a single
        Competitor of IBM represents more than [*] of LSI's total operating
        revenue and IBM reasonably believes that this situation is having a
        significant, detrimental effect on IBM's relationship with LSI under
        this Attachment; or (10) Products conform to specifications provided by
        IBM but are nevertheless incompatible with IBM's overall system unit
        design, to the extent that LSI had an opportunity to make the Product
        compatible pursuant to Section 3.12 of the Attachment.

             For the purposes of this Attachment, a "Competitor of IBM" shall
        mean any company which is directly, or through an Affiliate is
        indirectly: (i) involved in the development, manufacture or sales of
        information handling hardware through which activity it generates annual
        revenue in excess of [*], or (ii) involved in the development or sale of
        software or computer-related services through which activity it
        generates annual revenue in excess of [*].

     For the purposes of this Attachment, "Affiliate" shall mean entities that
     control, are controlled by or are under common control with, a party to
     this Attachment.

          21.4  IBM is not obligated to purchase and IBM shall have no liability
     to LSI with respect to:

             (1) products in IBM's possession or under IBM's control prior to or
        on the Effective Date of this Attachment;

             (2) products awarded by IBM to another supplier prior to the
        Effective Date of this Attachment or products derived from an
        Engineering Change to those products;

             (3) products that a customer requires to be provided by a source
        other than LSI; and

             (4) initial production quantities (generally, [*] from the date
        such Products are made generally available to the public) if IBM
        believes, in its sole and reasonable discretion, that it is necessary to
        produce these Products elsewhere due to concerns about engineering,
        Parts availability, process and manufacturing readiness, or plant volume
        capabilities, provided that IBM notifies LSI about the concerns and LSI
        is unable to resolve them to IBM's satisfaction before the order for
        initial production quantities must be placed.

          21.5 The parties agree that damages are difficult to ascertain and as
     a reasonable estimate of LSI's actual damages, and not as a penalty, IBM
     will pay LSI liquidated damages as set forth in this Section 21.5 for each
     Product that IBM purchased from another supplier in violation of this
     Section 21. Notwithstanding the foregoing, IBM will have no liability and
     shall not pay liquidated or other damages to the extent that the number of
     such Products purchased by IBM from another supplier in violation of
     Section 21 during each calendar year is no more than [*]: (a) all Products
     ordered by IBM during that calendar year from LSI; plus, (b) all such
     Products that IBM purchases from another supplier during that calendar year
     in violation of Section 21.

     IBM will pay [*] for each Product [*] by IBM from another supplier in
violation of Section 21 between the Effective Date of this Attachment and the
[*] of the Effective Date, for the number of such Products that is more than [*]
of all such Products ordered by IBM during the [*] from either LSI or another
supplier in violation of Section 21. This is the sole and exclusive remedy
available to LSI for IBM's failure to fulfill its
                                        16
<PAGE>

obligations under Section 21, and stands in lieu of all other remedies available
to LSI under this Agreement, at law, and in equity. LSI must bring any claim
under this Section 21.5 within [*] of the date LSI has actual knowledge of facts
giving rise to the claim, but in no event more than [*] after the date the claim
arises. If IBM purchases more than [*] of its [*] for a Product in any given
[*], then this Section 21.5 shall not apply and the parties shall follow the
dispute resolution mechanisms otherwise available to them.

     22.0 LSI Competitiveness

          22.1 IBM's commitment to purchase Products from LSI is contingent upon
     LSI remaining competitive for each Product and in each geography with
     regard to supplier performance criteria which include, without limitation:
     Price, Product quality, Lead Times, on-time delivery, technology, Product
     support and responsiveness. The determination of competitiveness will be
     made by IBM in IBM's reasonable judgment and sole discretion, acting in
     good faith. IBM may request LSI to provide such relevant data to
     demonstrate competitiveness. IBM may at any time test LSI's competitiveness
     relative to the industry on a periodic basis through a competitive RFQ
     process with other external suppliers, internal IBM suppliers, and/or a
     comparison of industry benchmark RFI data.

          22.2 In the event that IBM determines in its sole and reasonable
     discretion that LSI is noncompetitive pursuant to Section 22.1, then IBM
     shall provide written notice to LSI specifying the Product(s),
     geography(ies), and area(s) of performance in which LSI is noncompetitive.
     If LSI receives such notice and:

             (1) does not correct the identified noncompetitive performance to
        IBM's satisfaction or negotiate a resolution action plan to the matter
        which is satisfactory to IBM within [*] of said notice for price issues;
        or

             (2) does not correct the identified noncompetitive performance to
        IBM's satisfaction Of negotiate a resolution action plan to the matter
        which is satisfactory to IBM within [*] of said notice for all other
        performance issues:

then IBM may, in addition to its other rights tinder this Attachment and the
Agreement, source the affected Products from other suppliers and/or cancel any
unfulfilled WA(s) for the affected product(s) at no charge and without
liability.

     23.0 Indemnification

          23.1 General Indemnification.  LSI will defend, hold harmless and
     indemnify, including legal fees, Customers and IBM personnel against third
     patty claims that arise or are alleged to have arisen as a result of
     negligent or intentional acts or omissions of LSI or LSI personnel or
     breach by LSI of any term of this Attachment (including the product Unique
     Attachments) and the Agreement.

     LSI's obligation to indemnify IBM under this section shall be contingent on
IBM (i) notifying LSI promptly in writing of such a claim, (ii) giving LSI sole
control and authority to proceed as contemplated herein provided, that LSI shall
have sole control of any such claim or settlement negotiations, and (iii) giving
LSI proper and fail information and assistance to settle and/or defend any such
claim. Failure by IBM to notify LSI promptly in writing of such a claim will
relieve LSI of its obligations under this section only to the extent that LSI's
ability to defend the claim is prejudiced by such lack of notice.

     24.0 Assignment

     IBM may assign some or all of its rights and obligations under this
Attachment and the Agreement to third parties or its Affiliates, at IBM's sole
discretion, including, but not limited to, assigning the right to procure FRUs
to third-party service providers. LSI may assign some or all of its rights and
obligations under this Attachment and the Agreement to third parties or its
subsidiaries with prior written consent from IBM's Business Coordinator except
that LSI shall have the right to assign some or all of its rights and
obligations under this Attachment and the Agreement in connection with the sale
of all or part of its business that makes use of or sells the Products purchased
hereunder. Any unauthorized assignment of this #Attachment or the Agreement is
void.

     25.0 Order of Precedence

     Notwithstanding section 9.11 of the Agreement [*] and section 9.6 of this
Attachment, in the event of any conflict in the documents contained in the
Agreement. the order of precedence will be: (i) the relevant Product Unique
Attachment: (ii) the balance of this Attachment; and (iii) the Agreement [*].

     THIS ATTACHMENT AND ITS EXHIBITS, PRODUCT UNIQUE ATTACHMENTS, WAS, AND PULL
PROFILES ISSUED HEREUNDER, THE AGE THAT THIS ATTACHMENT IS ISSUED UNDER, AND THE
