organized and existing under the laws of Delaware and having its principal place
of business at 5742 West Harold Gatty Drive, Salt Lake City, Utah 84116
("Seller") on the one hand and

      3Com Corporation, a company organized and existing under the laws of
Delaware and having its principal place of business at 5400 Bayfront Plaza,
Santa Clara, California 95052 ("Buyer") on the other hand. "Seller and Buyer"
are hereinafter also collectively referred to as "Parties" and individually as a
Party.

      WHEREAS, Seller agrees to manufacture and sell to Buyer the Products (as
hereinafter defined) and Buyer agrees to purchase from Seller such Products,
subject to the terms and conditions of this Agreement.

1. DEFINITIONS

      A. "Affiliate": with respect to any Party, any other party directly or
indirectly controlling, controlled by, or under common control with such Party.
For purposes of this definition, "control" when used with respect to any party,
means the possession, directly or indirectly, of the power to direct or cause
the direction of the management and policies of such party, whether through the
ownership of voting securities, by contract or otherwise; the terms
"controlling" and "controlled" have meanings correlative to the foregoing.
Buyer's Affiliates are identified in Exhibit E, which may be changed by written
notice from Buyer to Seller from time to time.

      B. "BOM": Buyer's Bill of Materials.

      C. Buyer's "Authorized Agent": any of Buyer's Affiliates, or any third
party suppliers, subcontractors or contract manufacturers who desire to purchase
Products or Materials and whose credit worthiness is reasonably acceptable to
Seller, who purchase on a letter of credit basis, or whose payment obligations
are guaranteed by Buyer. Buyer's Authorized Agents are identified in Exhibit E,
which may be changed from time to time by written agreement between Buyer and
Seller.

      D. "Days": calendar days unless otherwise specified.


      E. "Excess Materials": Unique Materials on hand and ordered consistent

caused by Buyer.


      F. "Finished Goods Stockroom": the section of Seller's facility designated
as the area where the Product is delivered to Buyer.

      G. "Materials": component line items on the BOM, which are collectively
assembled to produce the Product.

      H. "Manufacturing Lead Time": the total aggregate lead time of that
component of the Product having the longest lead time, plus the time necessary
for receiving and inspecting all components for such Product, manufacturing the
Product, and systems integration, test and distribution, all as mutually agreed
upon by the Seller and Buyer.

      I. "MRP": Materials requirements planning.

      J. "NRE": non-recurring engineering expenses.


      K. "Obsolete Materials": Unique Materials on hand and ordered consistent
with Buyer's forecast at agreed-upon leadtimes which can no longer be used for
their designated Product and/or for which there is no forecast for the following
[*]


      L. "Performance Standards": those performance standards set forth in
Exhibit F, as may be modified from time to time by mutual written agreement of
the Parties.

      M. "Product(s)": the product(s) identified by Buyer's part number or
assembly identification name as more fully described in Buyer's Specifications.

      N. "Pull" means a replenishment driven process triggered by customer
consumption whereby Product is manufactured and delivered by Seller based upon
Buyer's replenishment demand, which is generated by actual use, disposition or
consumption of Product by Buyer; the overall objective being to minimize Seller
and Buyer's inventories while enabling greater flexibility and faster response
in fulfilling Buyer's variable replenishment demand.

      O. "Build Request" is a document Buyer provides to Seller on an as-needed
basis and serves as a replenishment request. The Build Request indicates, among
other things, the part number(s), quantity(s), delivery date(s), and
destination(s) of the Product(s) being requested.

      P. "Pull Product" shall mean Products, which may be purchased by Buyer
under a Pull Purchase Order pursuant to this Agreement, and for which Seller and
Buyer have jointly agreed are to be designated as pull Products.

      Q. "Blanket Purchase Order" is Buyer's blanket Purchase Order for a
Product. Blanket Purchase Orders shall reference this Agreement and include the
mutually agreed Price (as defined in Section 13A), but do not bind Buyer or
Seller as to total quantities purchased, delivery dates, or the total dollar
commitment of such Blanket Purchase Order.


                                       2

      U. "Unique Materials": Custom (i.e. specifically designed for the
Products) Materials or noncancellable and nonreturnable industry standard
Materials (i.e., that are not available from multiple suppliers or from a single
supplier with multiple customers).

2. PRECEDENCE OF DOCUMENTS

      The precedence of documents between Buyer and Seller shall be:

      A.    This Agreement, as it may be amended in writing by mutual agreement

      B.    A Purchase Order

      C.    Buyer's non-binding forecast

3. PURCHASE AND SUPPLY COMMITMENT

      A. Buyer agrees that it and its Authorized Agents shall purchase, and
Seller agrees to supply, a minimum of 5,000 production machine hours of
utilization per quarter at Buyer's Q2FY2000 standards on existing equipment as
of the Effective Date for existing Products (or applicable standards as mutually
agreed for new Products or new capital equipment for existing Products) during
the Initial Term of this Agreement. Notwithstanding the foregoing, if Seller
falls to meet the Performance Standards set forth in Exhibit F in all material
respects, or otherwise fails to comply with material obligations hereunder, or
Seller fails to make the minimum commitment available to Buyer in accordance
with Buyer's orders in any quarter due to a Materials shortage or otherwise (not
directly caused by Buyer), Buyer will be under no obligation to reach this
minimum in any quarter of such material noncompliance but will be under this
obligation in subsequent periods if such noncompliance is cured within the
Initial Term. Notwithstanding the foregoing, any failure of Seller to make
minimum commitments available to Buyer in accordance with Buyer's orders in any
quarter shall only relieve Buyer of its obligation to reach its minimum
commitment to the extent of such shortfall provided that Seller makes the
remainder of such commitment available in such quarter in accordance with
Buyer's orders.

      B. Any overage in purchase of Products of no more than [*]% that occurs
during any quarter will be credited towards the subsequent quarterly period and
any deficit in purchase of Products of no more than [*]% in any quarter may be
made up in the next quarter to the extent there is not a deficit in such
subsequent quarter. This minimum purchase commitment takes precedence over the



                                       3
<PAGE>


Flexibility Parameters of Exhibit D; Failure to meet the commitment is subject
to a [*] notice and cure period.


4. PURCHASE ORDERS, FLEXIBILITY, RESCHEDULES, CANCELLATIONS


      A. Buyer will provide a minimum of [*] continuous, Blanket Purchase Order
coverage. Blanket Purchase Orders may be submitted in the form of hard copy, by
facsimile, or by electronic transfer if there is an electronic data interchange
("EDI") agreement in place between Buyer and Seller. Purchase Orders will
specify part numbers, quantity, prices, product revisions, requested delivery
dates and delivery locations all of which shall be consistent with the terms
hereof. Any terms or conditions contained in the Purchase Order or in Seller's
acknowledgement or other document which are inconsistent with or in conflict
with the terms and conditions contained in this Agreement or which increase or
impose additional obligations, liabilities, or risks upon the other Party are
hereby expressly rejected and shall have no effect. Blanket Purchase Orders will
be for one part number per purchase order and indicate: (1) agreed-upon purchase
Price; (2) method for shipping, receiving and billing of Product shipped per the
"Build Request Process Flow" method set out in Exhibit G or as otherwise
mutually agreed; and (3) payment terms as defined in this Agreement. Blanket
Purchase Orders quantities are not considered for liability purposes or for use
in Materials planning and forecast requirements. Materials liability is set
forth in Exhibit D. Buyer shall communicate demand for long range and weekly
increments consistent with the Build Request Process Flow set forth in Exhibit G
or as otherwise mutually agreed.

      B. Alternatively, Buyer will provide a Blanket Purchase Order [*] at
the agreed-upon Price for the forecasted demand for [*]. Buyer will release
Build Requests for Products on a [*] basis for the quantities to be shipped
the following [*] based upon demand patterns and backlog status. On a
periodic basis at Buyer's discretion, Buyer may issue a Build Request
document to Seller, requesting delivery of Product pursuant to the Build
Request Process Flow set forth in Exhibit G. Such Build Requests shall be
Buyer's only commitment to purchase Products (subject to Section 3 above),
and Seller's only authorization to ship Product to Buyer. A Build Request may
be in electronic or written (including facsimile) form. Seller agrees to
multiple Build Requests per Day.

      C. When Buyer issues a Build Request, Products must be scheduled for
delivery at least [*] after Seller's receipt of the Build Request. If Buyer
requests Seller to ship Products in fewer than [*] after Seller's receipt of the
Build Request, Seller agrees to make commercially reasonable efforts to
accommodate Buyer's request.

      D. Buyer and Seller agree to, on a [*] basis, reconcile their respective
data records with respect to open Purchase Order quantity the quantity of
Product ordered, shipped and delivered pursuant to Buyer's Build Requests during
the previous [*] period.

      E. Seller will use commercially reasonable efforts, and will allocate
excess capacity at the Salt Lake City facility pro-rata based on customer unit
order volume among Buyer and other customers (to the extent Seller does not have
enough capacity to meet Buyer's orders beyond forecast and minimum commitment)
to meet Buyer's requested increases in capacity beyond


                                       4
<PAGE>

forecasted quantities within the Manufacturing Lead Time subject to Materials
availability, other scheduled manufacturing, and manufacturing capacity. If any
premium, expediting, or other increased charges over quoted costs are required
in order to meet Buyer's increased requirements, they must be approved in
advance by Buyer. Buyer agrees to pay for all such pre-approved costs that
represent out-of-pocket costs incurred by Seller. In addition, Seller commits at
no additional cost to Buyer to comply with the flexibility terms for Materials
and capacity availability as defined below provided that Seller is not obligated
to procure additional capital equipment to meet this obligation:

Materials and Capacity Availability Upside

       [*]              % Upside


       0-2                  [*]
       2-4                  [*]
       4-8                  [*]
       >8                   [*]


      F. Exhibit D sets forth the allowable outward reschedules, cancellations
and upward flexibility.


      G. Changes to Purchase Orders that are permissible under Exhibit D and
changes to its forecasts will be consolidated by Buyer who will take
commercially reasonable efforts to limit its requests to one request per [*]

      H. Purchase Orders shall not be considered as accepted until confirmed in
writing by an authorized representative of Seller. Seller shall make
commercially reasonable efforts to confirm Purchase Orders (except by written
mutual arrangement) within [*] after receipt. Notwithstanding the foregoing, if
Seller fails to accept or reject within [*], Seller will be deemed to have
accepted that Purchase Order. No additional or different provisions proposed by
either Party shall apply unless expressly agreed to in writing by both Parties.
Seller will accept Purchase Orders which are consistent with the terms and
conditions of this Agreement.

      I. Seller will meet the delivery dates specified by Buyer if such dates
are consistent with the Performance Standards set forth in Exhibit F.

      J. On a [*] basis Seller will provide Buyer with a list of all Materials
with leadtimes exceeding [*] for review and mutual approval. Upon mutual
approval, Seller will update the MRP with the mutually agreed current leadtimes.
Any Unique Materials that are required to be purchased beyond mutually agreed
leadtimes requires completion of the "Long Leadtime Authorization Form" set
forth in Exhibit H.



                                       5
<PAGE>

      K. Any Unique Materials item whose cost will change, with inventory or
liability still available, but less than a forecasted [*] production, will
result in a Price change, using a [*] method:


                                      [*]


      L. or such other method as mutually agreed.

5. ROLLING FORECAST

      Buyer will provide Seller with at least a [*] rolling non-binding
forecast, updated [*]. Buyer authorizes Seller to procure long lead-time
Materials consistent with Section 4J above in accordance with Buyer's forecasts
and flexibility requirements. Buyer further authorizes Seller to purchase
minimum buy items and reel quantities to support economic order quantities and
Materials requirement planning which may exceed authorized forecasts or Purchase
Orders. Seller agrees to inform Buyer of such purchases and Buyer shall have the
right to pre-approved all purchases of Unique Materials ordered in excess of
forecast. Some of Seller's orders to vendors and/or some Materials may be
designated by vendors as non-cancelable or non-returnable. All of these actions
may result in Materials procurement in excess of that required by Buyer's
Purchase Orders and forecasts. Buyer hereby authorizes Seller to make such
purchases as are reasonably necessary to meet Buyer's forecasts. Buyer will be
liable for, and Buyer's liability with respect to the procurement of Materials
will be limited to Excess and Obsolete Materials as set forth in Section 7 and
Section 8 below. For the avoidance of doubt, Seller will be responsible for
managing the disposition and liability of all industry standard Materials at no
expense or liability to Buyer (i.e., all non-Unique Materials). In addition,
Buyer may limit its liability hereunder by specifying to Seller in writing a
maximum amount. If Buyer elects to specify a maximum amount Seller will purchase
only to that amount and will notify Buyer of the impact to Buyer's
forecast/Purchase Orders.

6. PURCHASES BY BUYER'S AUTHORIZED AGENTS

      Seller agrees that all of the Buyer's Authorized Agents, wherever located,
shall be entitled to make purchases under this Agreement, and all such
purchases shall apply to the purchase commitments in Section 3, subject to
their credit worthiness being reasonably acceptable to Seller, unless they
purchase on a letter of credit basis or their payments are guaranteed by Buyer.
Any payment timing and credit limitations placed on Buyer's Authorized Agents,
other than those presented in this Agreement, will be agreed upon in writing by
both Parties. Seller agrees to notify Buyer of any credit limitations applicable
to Buyer's Authorized Agents.


                                       6
<PAGE>

7. EXCESS MATERIALS.

      With respect to any Excess Materials on hand, Seller will notify Buyer of
the amount and the cost of such Excess Materials in a consolidated, monthly
report. Buyer shall either (i) pay carrying costs for Excess Materials at a rate
of [*] per month as it ages greater than [*] after receipt of such monthly
notice by Buyer; or (ii) buy all Excess Materials at [*] to be held in bonded
stock for consumption based upon a forecasted demand within the next [*]. Seller
will use reasonable commercial efforts to sell Excess Materials.

8. OBSOLETE MATERIALS

      On a [*] basis, Seller will send Buyer a report which states the Materials
that are determined to be Obsolete Materials. Buyer will purchase Obsolete
Materials at [*] plus a [*] Materials acquisition charge. Buyer will provide
Seller a purchase order within [*] of confirmation of obsolescence. Seller will
use reasonable commercial efforts to sell Obsolete Materials.

9. TERM OF AGREEMENT

      This Agreement shall become effective upon execution by authorized
representatives of both Parties. This Agreement shall expire [*] after the date
of execution by both Parties ("Initial Term"), unless this Agreement is
terminated earlier pursuant to Section 25 or 26 and shall be automatically
extended for one or more additional successive [*] periods (each, a "Renewal
Term"), unless one Party notifies the other Parry in writing at least [*] prior
to the beginning of such additional period that it desires not to extend.
Minimum purchase obligations pursuant to Section 3 shall terminate upon
expiration of the Initial Term and shall not be renewed in any Renewal Term. The
Initial Term, along with any Renewal Terms, is referenced to herein as the
"Term" of this Agreement.

10. PRODUCTION CAPACITY

      All manufacturing will be conducted at Seller's Salt Lake City, Utah
facility unless otherwise agreed. Seller shall make available the necessary
capacity at such facility to meet Buyer's production requirements, as provided
by Buyer in Sections 4 and 5. Seller will notify Buyer on a [*] basis to confirm
that capacity is available for the forecasted period for the following [*] and
to advise Buyer of any capacity constraints for the remainder of the forecast
period. Buyer agrees to not unreasonably withhold approval of additional
production facilities in the event of extraordinary demand beyond Buyer's
forecasts. However, to the extent Seller does not have sufficient capacity to
meet Buyer's orders beyond forecast and minimum commitments, Seller will
allocate capacity at the Salt Lake City facility pro-rata among Buyer and other
customers, based on customer unit order volumes, and Buyer is under no
obligation to approve the manufacture of Products at any other of Seller's
locations if Buyer determines in its sole discretion that such location does not
meet Buyer's business needs.



                                       7
<PAGE>

11. FLEXIBILITY CAPABILITY

      Buyer may issue change requests for Product quantities and schedule dates,
and Seller shall maintain the necessary capacity to accommodate such changes, in
accordance with the Flexibility Parameters attached as Exhibit D (the
"Flexibility Parameters"). Changes made in accordance with the Flexibility
Parameters will not incur cost or liability for Buyer.

12. MATERIALS TRANSFER

      Seller agrees to buy, from time to time, Buyer's on-hand Materials that
are in excess of Buyer's own production requirements and are needed for Seller's
production within the open Purchase order period. Seller also agrees to sell
Materials in excess of Seller's production requirements to Buyer, to any of
Buyer's Authorized Agents or anyone else designated by Buyer whose credit
worthiness is reasonably acceptable to Seller, who purchases on a letter of
credit basis, or whose payment obligations are guaranteed by Buyer. Transfer
quantities and payment terms will be mutually agreed on a case-by-case basis.
Prices shall be at Buyer's or Seller's, as the case may be, actual purchase
price for the transferred Materials.

13. PRICING

      A. The prices for Products sold pursuant to this Agreement are set out in
Exhibit A to this Agreement (hereinafter referred to as "Prices"). Any change to
the Prices set forth in Exhibit A shall be identified by an amendment to Exhibit
A which must be approved by authorized representatives of both Parties. All
Prices shall be in US Dollars, unless otherwise negotiated and documented in
Exhibit A.

      B. Delivery is at Seller's dock or the Seller's Finished Goods Stockroom,
whatever the case may be. Buyer shall pay all applicable out-bound freight
costs, out-bound export costs, including any pre-shipment inspection charges if
mandated by the authorities of the country of exportation, as well as all
out-bound export brokerage, documentation, processing, customs and any other
export fees and taxes for export out of the United States at Buyer's request.
Buyer also agrees to pay all sales and use taxes on Products or Materials sold
to Buyer to Seller's delivery point or furnish Seller with tax exemptions. Both
Parties agree that Prices shall include all costs of the Product manufacture,
including pack-out of finished goods, as well as charges such as packaging,
palletizing, packing, crating, and storage as needed.

      C. All Materials shall be purchased from suppliers on Buyer's approved
vendor list (the "AVL") as revised from time to time. Buyer agrees to use
reasonably commercial efforts to have Buyer's suppliers extend to Seller (as
agreed to by the applicable supplier) any and all Buyer negotiated Materials
pricing solely for purchases for Products manufactured under this Agreement.
Buyer will consider requests by Seller to permit such pricing to be extended to
Seller for purchases for Seller's other customers (as agreed to by the
applicable supplier).

      D. Any Materials inspection processes that are in place at the
manufacturing facility as of the Effective Date are included in the negotiated
Price. Materials cost reductions negotiated by


                                       8
<PAGE>


Buyer with component suppliers will also be factored into Buyer's Materials
cost. Cost reductions negotiated by Seller for Buyer-controlled Materials from
alternate suppliers that are not on Buyer's approved vendor list, but which have
been approved by Buyer for inclusion on the AVL, will be [*] following first
production shipment of such components by the new supplier to Seller, after
which time the cost reduction will be factored fully into Buyer's Materials
cost.

14. DELIVERY

      A. Seller will deliver the Product no more than [*] before and [*] after
the agreed delivery date, but if deliveries are delayed by causes beyond
Seller's control, will promptly notify Buyer and may make partial deliveries.
If Seller continues to be unable to meet the agreed delivery date due to
supply constraints, it will provide Buyer a report of such supply constraints
and proposed actions to minimize the impact of these constraints. If delivery
is more than [*] late due to causes entirely within Seller's control, Seller
will pay the incremental cost of expedited shipment. Delivery terms are
Ex-Works (as defined in the International Chamber of Commerce "Incoterms"
1990 edition) from Seller's production facility. Title and risk of loss to
the Product passes to the Buyer at the point of delivery, i.e. Seller's dock
or Sellers' Finished Goods Stockroom.

      B. Seller shall segregate and clearly designate the Products as belonging
to Buyer. Seller shall maintain insurance coverage in a form reasonably
acceptable to Buyer to cover risk of loss to the Products until delivery to the
common carrier.

15. PACK-OUT, PACKING, MARKING, AND SHIPPING INSTRUCTIONS

      A. All Product shall be finished, packed-out, prepared and packed for
shipment in a commercially reasonable manner with the intent to secure the
lowest transportation rates and meet carrier's requirements and those set forth
in Buyer's Pack-Out and Packaging Specifications which are attached hereto as
Exhibit C.

      B. Each shipping container shall be marked to show Buyer's Purchase Order

16. QUALITY STANDARDS AND CERTIFICATION

      A. MANAGEMENT REVIEW PROCESS. The Parties intend to maintain active and
open communications at both the program level and at the strategic level, and
agree to engage in periodic reviews of all applicable activities encompassing
the relationship. Executive representatives from both Parties will meet no less
than [*] to review all major elements of this Agreement and to jointly agree
upon updated performance metrics for this Agreement. Initially, the Parties
intend to rotate these meetings between Seller's locations and Buyer's corporate
facilities in Santa Clara,



                                       9

California. Special attention will be paid to Buyer programs specific to the
host site, although the Parties will also follow a standard agenda covering the
total business. This agenda will include reviewing Buyer future Product roadmaps
and schedules, organizational updates, future manufacturing and process
improvements by Seller's business reviews, and performance metrics reflecting
activities during the period since the last review.

      B. PERFORMANCE METRICS. Performance Metrics as set forth in Exhibit F will
include, but are not limited to, the following: (i) total Buyer-Seller business
level; (ii) Seller product quality and yields; (iii) Seller on-time delivery
performance; (iv) Buyer forecast accuracy; (v) Seller inventory summary; (vi)
Buyer EC activity; (vii) lead time characterization; (viii) Seller prototype
on-time delivery and quality performance; and (ix) Seller future/projected
manufacturing/process and cost improvements. Seller agrees to maintain quality
standards, measurement practices, quality reports, and inspection processes as
they exist at the Salt Lake City facility as of the Effective Date subject to
any changes as may be mutually agreed. In addition, Seller will work with Buyer
to develop mutually-agreeable closed-loop quality and corrective action
processes on a going forward basis. Seller shall maintain the quality plan in
effect at the Salt Lake City facility as of the Effective Date. The Parties
shall cooperate to develop a mutually acceptable quality plan incorporating such
existing plan at a minimum on a going forward basis. Upon request of either
Party, the Parties will cooperate to document such plan in writing. The Parties
shall engage in quarterly reviews and weekly conference calls to track
performance and update such plan.

      C. Seller agrees that all Products will conform in all material respects
to the Specifications for the part number stated on the BOM or Buyer's Purchase
Order, the Specifications for the manufacture and pack-out of the Products, and
to the workmanship specifications of IPC-610B Class 2 as modified from time to
time, which are set forth in Exhibits B and C, and to the then currently
accepted commercial manufacturing practices. For the avoidance of doubt, as used
in this Agreement "material" includes without limitation any non-conformity that
may cause a customer to return a Product.

      D. Seller will supply qualification samples to Buyer upon request. Buyer
shall provide written notification to Seller of the results of qualification
testing of each Product. If the sample is approved by Buyer, then Buyer will be
deemed to have accepted the BOM for the qualification samples and the processes
performed by Seller will be deemed to meet the appropriate Specifications.

      E. Buyer shall have the right to purchase spare Materials for the Products
in order to perform internal maintenance, support, and repair and for lab stock
and testing purposes. Such purchases shall be governed by the applicable terms
and conditions set forth in this Agreement.

      F. Seller will conform to the requirements of ISO 9002 at all times in
manufacturing the Products hereunder. Seller agrees that it currently is or
will, within twelve (12) months of the Effective Date of this Agreement become
certified under ISO 9002, and during the term of this Agreement will remain ISO
9002 certified. If at any time hereafter certification under ISO 9002 is no
longer generally appropriate, Seller will ensure that it is certified under
another comparable or higher standard which is reasonably acceptable to Buyer.


                                       10
<PAGE>

      G. Seller agrees that it will perform final "out-of-box" testing of a
sample of the Products to verify that the Products conform to the Specifications
in all material respects prior to delivery to Buyer. If any Products in the
sample deviate from the Specifications, Seller shall rework all defective
Products in the lot being sampled to render them compliant with the
Specifications in all material respects. Test methods and test procedures shall
be as currently in place at the Salt Lake City facility or as otherwise agreed
to by both Parties.

      H. If Buyer returns defective Products to Seller, Seller agrees to
implement on a prompt basis appropriate actions as necessary to minimize the
possibility that additional defective Products will be delivered to Buyer, and
further agrees as soon as reasonably possible to implement appropriate
corrective actions as necessary to prevent reoccurrence of the defect. Seller
further agrees to conduct a detailed failure analysis and to report the failure
analysis data to Buyer within [*] of receipt of the defective Product at
Seller's location. Seller agrees to preserve and maintain all data associated
with Product failure analysis and corrective actions and to make that data
available to Buyer upon request at no charge provided that Seller shall not be
obligated to preserve and maintain such data beyond the period required by its
ISO 9002 certification or the warranty period for the Products, whichever is
greater. Seller agrees to participate in Buyer's closed-loop corrective action
process.

      I. Seller agrees to advise Buyer in writing of any material changes to
manufacturing processes and any changes to Materials, sources of supply, or
process chemistries, test procedures, quality reporting or other major
processes, and to ensure that any such changes do not compromise specifications,
quality, or reliability of Products ordered pursuant to this Agreement. In the
case of changes to Materials or sources of supply, such notice shall be provided
no less than the [*] prior to the effectiveness of such change. Seller may not
make any such changes without prior written approval from Buyer. In the event a
Seller-proposed change fails Buyer's qualification, Seller is obligated to
provide the existing qualified Product until the proposed changed can be
qualified.

17. INSPECTION, TESTING, AND ACCEPTANCE

      A. Products purchased pursuant to this Agreement shall be subject to
inspection, testing, and acceptance by Buyer, which shall occur within [*] of
delivery of Product.

      B. All Products built by Seller for Buyer will have a specific set of
Product testing procedures and acceptance criteria as currently in place at the
Salt Lake City facility or as otherwise agreed to by both Parties. Upon request
of either Party, the Parties will cooperate to document such procedures and
criteria in writing. Should Products or Seller's processes be found to be
non-conforming, Seller will withhold shipping Product until such non-conformance
is resolved to Buyer's reasonable satisfaction. Buyer will not be responsible
for Products that fail to meet agreed upon acceptance criteria.

      C. All Products are subject to Buyer's inspection and test at Buyer's
facility before final acceptance. Buyer has a [*] acceptance period after
delivery. In the event of non-conforming



                                       11
<PAGE>


order (i.e. failure to meet Purchase Order or failure to meet warranty), Buyer
has the right to reject the order in whole or in part within such [*] period.

      D. Upon [*] notice, Buyer shall have the right to perform vendor
qualifications and/or on-site inspections at Seller's manufacturing facilities
during Seller's normal business hours. If an inspection or test is made on
Seller's premises, Seller shall provide Buyer's inspectors with reasonable
facilities and assistance at no additional charge. In the event that any on-site
inspection of the Products indicates that the Products do not conform to the
requirements of this Agreement, Seller shall not ship such Products to Buyer
until such nonconformity has been corrected to Buyer's reasonable satisfaction
and Buyer has approved shipment of such Products in writing. This does not
preclude, prevent or limit Buyer's right to perform acceptance testing at
Buyer's facilities.

18. RETURN OF PRODUCT

      A. In the event Buyer detects non-conforming Products prior to acceptance,
a Non-Conforming Materials Report (NCMR) and/or a Corrective Action request
(CAR) shall be provided to Seller and Seller shall submit an initial response to
such CAR within [*] after receipt. Seller must provide a Return Materials
Authorization (RMA) within [*] after receipt of request for an RMA from Buyer.

      B. Buyer may reject and return any defective Product to Seller at Seller's
expense. Seller agrees to reimburse Buyer all reasonable and actual freight and
handling costs associated with return of any defective Product. Seller will
return conforming Products freight prepaid as per the following schedule to
Buyer or issue appropriate credit no later than [*] or as mutually agreed by
both Parties, from the date Seller receives the defective Product.

is found to be free of defects shall be subject to a "No Defect Found Charge" as
specified in Exhibit A. However, Seller will waive any NDF Charges on Products
returned for repair, if returned Products result in an NDF rate not exceeding
[*] of the monthly unit volume. For an NDF rate greater than [*] but not more
than [*] the Parties will mutually agree upon allocation of the NDF Charge.

      C. If pending the analysis of returned Products by Seller Buyer is in
urgent need of Product, Buyer may issue a Purchase Order to replace the Products
to which the CAR pertains. Seller will expedite such Purchase Order at Buyer's
request and, if requested by Buyer, will ship the order by.

without consent to an entity that succeeds to all or substantially all of the
business or assets of such Party. Without limiting the foregoing, this Agreement
will be binding upon and inure to the benefit of the Parties and their permitted
successors and assigns.

      Notwithstanding the foregoing, Seller shall have the right upon written
notice to Buyer to assign this Agreement to a wholly-owned (direct or indirect)
subsidiary of Seller's ultimate parent, such arrangement not to affect the

      Nothing herein shall prohibit Seller from granting in favor of its lenders
a security interest in any accounts receivable by Seller from Buyer under this
Agreement.

31. COMPLIANCE WITH LAWS

      Seller agrees that its performance under this Agreement shall comply with
all applicable laws including without limitation laws governing its relationship
with its employees, agents or subcontractors. Buyer agrees that its performance
under this Agreement shall comply with all applicable laws including without
limitation laws governing its relationship with its employees, agents or
subcontractors.

32. PATENT, COPYRIGHT AND TRADEMARK INDEMNITY

      A. Indemnity by Seller. Seller will, at its expense, defend, indemnify and
hold Buyer, its Affiliates, officers and directors harmless from any costs,
expenses (including reasonable attorney's fees), losses, damages, court
judgments or awards or liabilities (collectively, "Damages") incurred as a
result of any claim that any Service or Product provided by Seller to Buyer
pursuant to this Agree-


                                       21
<PAGE>

ment infringes or is alleged to infringe any patent, copyright, trade secret,
trademark mask work right or other proprietary right(s) of a third party, but
solely to the extant such infringement or alleged infringement arises out of or
relates to a Seller Responsibility; provided that Seller is promptly notified by
Buyer, rendered reasonable assistance by Buyer (at Seller's expense) and
permitted to control the defense or settlement of such claim. As used herein,
"Seller Responsibility" means any aspect of the manufacture of the Products or
performance of the Services that is not specifically required in writing by
Buyer in its specified designs, Materials, processes or other instructions and
with respect to which there is a non-infringing alternative available to
implement such requirements, or any deviations from such requirements by Seller
or its agents. For the avoidance of doubt, a Seller Responsibility occurs with
respect to any discretionary action by Seller in the manner of implementing
Buyer's requirements if a non-infringing alternative exists. Without limiting
the foregoing, such indemnification shall not apply to infringing combinations
to the extent arising from the combination of the Product with other items in
which the combination was not performed by Seller or its agents or from claims
for infringement to the extent arising from changes to the Products not made by
Seller or its agents.

      B. Indemnity by Buyer. Buyer will, at its expense, defend, indemnify and
hold Seller and its Affiliates, officers and directors harmless from Damages
incurred as a result of any claim that any Product or Service provided by Seller
to Buyer hereunder infringes or is alleged to infringe any patent, copyright,
trade secret, trademark, mask work right or other proprietary right(s) of a
third party, except to the extent that such infringement or alleged infringement
arises out of or relates to a Seller Responsibility, and except to the extent
Seller has indemnification coverage from the applicable supplier with respect to
any Buyer-Specified Materials Infringement Claim; provided that Buyer is
promptly notified by Seller, rendered reasonable assistance by Seller (at
Buyer's expense) and permitted to control the defense or settlement of such
claim. Such indemnification shall not apply to infringing combinations arising
from the combination of Buyer's requirements with other items that are not
Buyer's requirements.

      C. Buyer-Specified Materials Infringement Claim. Seller will use
reasonable commercial efforts to obtain indemnification protection covering
Seller (and Buyer if possible) from its suppliers of Buyer-Specified Materials
for any claim that the Buyer-Specified Materials provided by suppliers infringes
or is alleged to infringe any patent, copyright, trade secret, trademark, mask
work, or other proprietary right(s) of a third party (a "Buyer-Specified
Materials Infringement Claim"), and Seller will use reasonable commercial
efforts to pass through to Buyer any indemnification protection that is so
obtained. As used herein, "Buyer-Specified Materials" means any Materials that
are specifically required in writing by Buyer and with respect to which there is
no non-infringing alternative available to implement such requirement. Where
Seller has obtained indemnification protection from a supplier of
Buyer-Specified Materials and is unable to pass through such indemnification
protection to the Buyer and a Buyer-Specified Materials Infringement Claim is
made against Buyer, Seller agrees that it will indemnify Buyer for Buyer's
Damages incurred as a result of such Buyer-Specified Materials Infringement
Claim, but such indemnification by Seller shall be provided only to the extent
Seller is able to obtain indemnification from such supplier using reasonable
commercial efforts and after application of such indemnification amount against
Damages incurred by Seller in connection with such Buyer-Specified Materials
Infringement Claim.


                                       22
<PAGE>

All reasonable costs of outside counsel pre-approved by Buyer to enforce such
indemnification protection from such supplier of Materials, to the extent
incurred in respect of Seller's indemnification of Buyer under this Section 32C,
shall be reimbursed by Buyer.

      D. Additional Obligations. Should the use of any Product by Buyer or its
customers be enjoined because of a Seller Responsibility, Seller shall (or in
the event Seller wishes to minimize its potential liability hereunder arising
from an infringement claim based on a Seller Responsibility, Seller may) either
(i) substitute a fully equivalent non-infringing unit of the Product for each
affected unit of the Product sold to Buyer; (ii) modify the infringing Product
so that it no longer infringes but remains functionally equivalent (iii) obtain
for Buyer, at Seller's expense, the right to continue to make, use and sell the
Product; or if none of the foregoing is feasible (iv) refund to Buyer the
purchase price paid therefor and accept return of the infringing Products.

33. CAPACITY PLANNING


      A. Seller agrees to review forecasts provided by Buyer and advise Buyer if
Seller anticipates that it will be unable to achieve the requested volumes.
Buyer's volume forecasts will be provided to Seller according to Section 5.
Seller may from time to time request Buyer to review Buyer's forecast and advise
of any changes and Buyer will do so. Seller agrees to provide Buyer with either
1) confirmation of feasibility of the forecast received, or 2) notice of
specific feasibility issues with the forecast received within [*] of receiving
said forecast.


      B. If Buyer's rolling forecast exceeds Seller's available maximum capacity
for Buyer, Seller shall advise Buyer of the limitations in the capacity and
provide a response in writing as described in the Purchase Order and rolling
forecast articles.

34. GRATUITIES

      Each Party represents and warrants that it has not offered or given and
will not offer or give any employee, agent, or representative of the other Party
any gratuity with a view toward securing any business from the other Party or
influencing such person with respect to the business between the Parties.

35. INSURANCE AND STATUTORY OBLIGATIONS

      If either Party's work under this Agreement requires access to any of the
other Party's premises or the premises of the other Party's buyers, suppliers,
or locations where the other Party conducts business, or with material or
equipment furnished by the other Party, both Parties shall take all necessary
precautions to prevent the occurrence of any injury to persons or property
during the progress of such work and, except to the extent that such injury is
due to the other Party's negligence or willful misconduct, each Party shall
indemnify the other Party against all loss which may result in any way from any
negligence or willful misconduct of the Party, its employees, servants, agents,
or subcontractors, and each Party shall maintain such insurance as shall protect
the other Party from such risks and from any statutory liabilities arising
therefrom and shall provide evidence of such insurance to the other Party upon
request.


                                       23
<PAGE>

36. INSURANCE COVERAGE


      A. Seller will provide evidence of product liability insurance in a form
reasonably acceptable to Buyer in the amounts of [*] per occurrence and [*]
aggregate per year, will maintain in effect such insurance for a period of [*]
after termination of such Agreement, and will provide Buyer with a certificate
of insurance.

      B. Buyer will provide evidence of product liability insurance in a form
reasonably acceptable to Seller in the amounts of [*] per occurrence and [*]
aggregate per year, and will maintain in effect such insurance for a period of
[*] after termination of such Agreement and will provide Seller with a
certificate of insurance.


37. CONFIDENTIAL INFORMATION

      A. "Confidential Information" means any information: (i) disclosed by one
Party (the "Disclosing Party") to the other (the "Receiving Party"), which, if
in written, graphic, machine-readable or other tangible form is marked as
"Confidential" or "Proprietary," or which, if disclosed orally or by
demonstration, is identified at the time of initial disclosure as confidential
and is summarized in writing and similarly marked and delivered to the Receiving
Party within thirty (30) Days of initial disclosure; (ii) which at the time it
is disclosed is or should reasonably be known by the Receiving Party to be
proprietary or confidential information of the Disclosing Party, or (iii) which
is otherwise deemed to be "Confidential Information" by the terms of this
Agreement. Notwithstanding the foregoing, Buyer's Confidential Information shall
include without limitation all Specifications of the Product. As used in this
Section 37A, the terms "Receiving Party" and "Disclosing Party" may be
understood to include, as appropriate under the circumstances, 3Com or its
subsidiaries or Palm or its subsidiaries, as applicable, and MSL or the MSL
Affiliates.

      B. Confidential Information Exclusions. Confidential Information will
exclude information that the Receiving Party can demonstrate is: (i) now or
hereafter, through no unauthorized act or failure to act on Receiving Party's
part, in the public domain; (ii) known to the Receiving Party from a source
other than the Disclosing Party (including former employees of the Disclosing
Party) without an obligation of confidentiality at the time Receiving Party
receives the same from the Disclosing Party, as evidenced by written records;
(iii) hereafter furnished to the Receiving Party by a third party as a matter of
right and without restriction on disclosure; (iv) furnished to others by the
Disclosing Party without restriction on disclosure; or (v) independently
developed by the Receiving Party without use of the Disclosing Party's
Confidential Information. Nothing in this Agreement shall prevent the Receiving
Party from disclosing Confidential Information to the extent the Receiving Party
is legally compelled to do so by any governmental investigative or judicial
agency pursuant to proceedings over which such agency has jurisdiction;
provided, however, that prior to any such disclosure, the Receiving Party shall
(a) assert the confidential nature of the Confidential Information to the
agency; (b) immediately notify the Disclosing Party in writing of the agency's
order or request to disclose; and (c) cooperate fully with the Disclosing Party
in protecting against any such disclosure and/or obtaining a protective order
narrowing the scope of the compelled disclosure and protecting its
confidentiality.


                                       24
<PAGE>

      C. Confidentiality Obligation. The Receiving Party shall treat as
confidential all of the Disclosing Party's Confidential Information and shall
not use such Confidential Information except as expressly permitted under this
Agreement. Without limiting the foregoing, the Receiving Party shall use the
same degree of care and means that it utilizes to protect its own information of
a similar nature, but in any event not less than reasonable ease and means, to
prevent the unauthorized use or the disclosure of such Confidential Information
to third parties. The Confidential Information may be disclosed only to
employees or contractors of the Receiving Party with a "need to know" who are
instructed and agree not to disclose the Confidential Information and not to use
the Confidential Information for any purpose, except as set forth herein;
provided, however, in the case of Buyer, the term "employees or contractors of a
Receiving Party" shall include employees and contractors of Buyer and its
Authorized Agents (but with respect to Authorized Agents who are not Affiliates
disclosure shall be limited to the extent necessary to enable such Authorized
Agents to purchase under this Agreement). The Receiving Party shall have
appropriate written agreements with any such employees or contractors sufficient
to comply with the provisions of this Agreement. A Receiving Party may not
alter, decompile, disassemble, reverse engineer, or otherwise modify any
Confidential Information received hereunder and the mingling of the Confidential
Information with information of the Receiving Party shall not affect the
confidential nature or ownership of the same as stated hereunder.

      D. Confidentiality of Agreement. Each Party agrees that the terms and
conditions, but not the existence, of this Agreement will be treated as the
other Party's Confidential Information and that no reference to the terms and
conditions of this Agreement or to activities pertaining thereto may be made in
any form of press release or public statement without first consulting with the
other Party; provided, however, that each Party may disclose the terms and
conditions of this Agreement: (i) as may be required by law; (ii) to legal
counsel of the Parties; (iii) in connection with the requirements of an initial
public offering or securities filing; (iv) in confidence, to accountants, banks,
and financing sources and their advisors; (v) in confidence, in connection with
the enforcement of this Agreement or rights under this Agreement; or (vii) in
confidence, in connection with a merger or acquisition or proposed merger or
acquisition, or the like.

      E. No Confidential Information of Other Parties. Each Party represents and
warrants to the other that it has not used and shall not use in the course of
its performance hereunder, and shall not disclose to the other, any confidential
information of any third party, unless it is expressly authorized in writing by
such third party to do so.

      F. Required Disclosure. In the event the Receiving Party is required to
disclose the Disclosing Party's Confidential Information pursuant to the order
or requirement of a court, administrative agency, or other governmental body,
the Receiving Party shall provide prompt notice thereof to the Disclosing Party
and shall use its reasonable efforts to obtain a protective order or otherwise
prevent public disclosure of such information.

38. PUBLIC ANNOUNCEMENTS.

      Seller and Buyer agree to consult with each other before issuing any press
release or making any public statement with respect to this Agreement prior to
the Closing Date (as such term is


                                       25
<PAGE>

defined in the Asset Purchase Agreement) and, except as may be required by
applicable law will not issue any such press release or make any such public
statement prior to such consultation. Seller and Buyer agree that the initial
press release to be jointly issued by the Parties with respect to the
transactions contemplated by this Agreement shall be in the form heretofore
agreed.

39. COUNTRY OF ORIGIN

      For each Product purchased under this Agreement, Seller shall furnish
Buyer with country of origin (manufacture), by quantity and part number (Buyer's
and Seller's).

40. PROPERTY FURNISHED BY BUYER

      Any tools, drawings, specifications, or other Materials furnished by Buyer
for use by Seller in its performance under this Agreement or any Purchase Order
issued hereunder shall be identified and shall remain the property of Buyer and
shall be used by Seller only in its performance hereunder and Seller shall, at
Buyer's expense, take such action as Buyer may reasonably request to give full
legal effect to Buyer's rights therein. Such property shall be returned to Buyer
at Buyer's cost, upon request, to destination specified by Buyer in good
condition, except for normal wear and tear. Buyer shall maintain, or pay to
maintain, any Buyer-owned property in use by Seller.

41. GENERAL

      A. Any obligations and duties which, by their nature, extend beyond the
expiration or earlier termination of this Agreement, including Sections 18, 20,
24, 26, 27, 30, 32, 36, 37, 40, and 41 (collectively, the "Surviving
Obligations") shall survive any such expiration or termination and remain in
effect. Termination shall not relieve any Party from its liability for breach.

      B. If any provision or provisions of this Agreement shall be held to be
invalid, illegal or unenforceable, such provision shall be enforced to the
fullest extent permitted by applicable law and the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby. Any waiver of any kind by a Party of a breach of this
Agreement must be in writing, shall be effective only to the extent set forth in
such writing and shall not operate or be construed as a waiver of any subsequent
breach. Any delay or omission in exercising any right, power or remedy pursuant
to a breach or default by a Party shall not impair any right, power or remedy
which either Party may have with respect to a future breach or default.

      C. To the extent the laws of the United States are applicable, Seller
hereby gives assurance to Buyer that it shall not export, re-export or otherwise
disclose, directly or indirectly, technical data received from Buyer or the
direct product of such technical data to any person or destination when such
export, re-export or disclosure is prohibited by the laws of the United States
or regulations of a Department of the United States. This Agreement is
considered to be Buyer and Seller Confidential Information.

      D. The entire agreement between the Parties is incorporated in this
Agreement and Exhibits, and it supersedes all prior discussions and agreements,
both oral and written, between the Parties


                                       26
<PAGE>

relating to the subject matter hereof. This Agreement can be modified only by a
written amendment duly signed by persons authorized to sign agreements on behalf
of both Parties, and shall not be supplemented or modified by any course of
dealing or trade usage. Variance from or addition to the terms and conditions of
this Agreement in any Purchase Order, or other written notification from Seller
will be of no effect. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument. This Agreement
shall become effective when each party hereto shall have received a counterpart
hereof signed by the other party hereto.

      E. Exhibits specified in this Agreement shall be attached hereto and by

      F. The construction, validity, and performance of this Agreement and any

      G. Each of the Parties agrees that all actions, suits or proceedings
arising out of or based upon this Agreement or the subject matter hereof shall
be brought and maintained exclusively in the state or federal courts located in
the State of New York. Each of the parties by execution hereof (i) hereby
irrevocably submits to the jurisdiction of the state and federal courts located
in the Borough of Manhattan, City of New York, State of New York for the purpose
of any action, suit or proceeding arising out of or based upon this Agreement or
the subject matter hereof and (ii) hereby waives to the extent not prohibited by
applicable law, and agrees not to assert, by way of motion, as a defense or
otherwise, in any such action, suit or proceeding, any claim that it is not
subject personally to the jurisdiction of the above-named court, that it is
immune from extraterritorial injunctive relief, that his or its property is
exempt or immune from attachment or execution, that any such action, suit or
proceeding may not be brought or maintained in the above-named court should be
dismissed on the grounds of forum non conveniens, should be transferred to any

<PAGE>

by the laws of the State of New York, agrees that service of process by
registered or certified mail, return receipt requested, at the address specified
in or pursuant to Section 30 hereof is reasonably calculated to give actual
notice and waives and agrees not to assert by way of motion, as a defense or
otherwise, in any such action, suit or proceeding any claim that service of
process made in accordance with Section 30 hereof does not constitute good and
sufficient service of process. The provisions of this Section 41G shall not
restrict the ability of any party to enforce in any court any judgment obtained
in the state or federal courts located in the State of New York. [*]

      H. Buyer and Seller agree to conduct joint quarterly business reviews with
Senior Management of both Parties for the purpose of reviewing the ongoing
operational performance of Buyer and Seller as it relates to this Agreement,
discuss anticipated business conditions, corrective and preventive action plans
as necessary and appropriate respective strategic business decisions.

      MSL hereby joins this Agreement for the purposes set forth in this
paragraph. MSL hereby guarantees to Buyer the performance by Seller of the
obligations of Seller under this Agreement, and, in the event of default by the
Seller of any such obligations, MSL agrees to perform all such obligations as if
MSL were Seller under this Agreement (subject to any limitations which would

payment, acceptance or protest under this Agreement; (b) discharge due to the

collection, enforcement or recovery of all or any part of any obligations
hereunder from Seller; or (iii) exercise or assert any other right or remedy to
which Buyer is or may be entitled in connection with any such obligations
