         issue revisions of that forecast to Manufacturer monthly ("Forecast",
         as initially shown in Exhibit C and updated on a monthly basis
         beginning thirty (30) days after the Effective Date). Manufacturer will
         purchase materials to support Purchase Order demand ("Materials").

         reviews of those Materials subject to such minimum or economic order
         quantity requirements. Purchaser is responsible, and will pay in
         accordance with Section 4(a), for Material purchased to support
         Purchaser's Purchase Orders, to fulfill the first sixty (60) days of
         the Forecast as in effect from time to time, or with Purchaser's
         pre-approval, purchased to support Purchaser's non-binding Forecast. If
         in case of Purchaser requests schedule reductions or cancellations,
         Manufacturer will use commercially practicable efforts to reschedule or
         cancel such Materials. Purchaser will maintain a minimum of sixty (60)
         days of Products on order at all times. Each Purchase Order shall
         become effective upon acceptance of the order by Manufacturer.

         delivery schedules.

e.       All Purchase Orders issued by Purchaser shall contain the following

         Purchaser will provide blanket orders to Manufacturer to support
         Manufacturer's assembly of Product to a certain level of assembly.
         These lower level assemblies would then be configured and shipped per
         subsequent orders issued by Purchaser (the parties will work in good
         faith to reach agreement on the details of this model prior to
         commencement of standard Product shipments, which agreement will be in
         writing and signed by both parties).

g.       Any Material deemed obsolete due to an ECO or no future scheduled
         demand will be reported to Purchaser on a monthly basis. Purchaser

                  within a reasonable time after Purchaser or Purchaser's
                  customer acknowledges receipt of Products.

         ii.      Purchaser shall forward defective Products to Manufacturer at
                  Manufacturer's expense. Manufacturer shall use its commercial
                  best effort to return the repaired or replaced Products
                  freight prepaid by Manufacturer to Purchaser or other
                  Purchaser specified location no later than thirty (30) days

                  original warranty period, whichever is longer.

                     ARRIS - PLEXUS MANUFACTURING AGREEMENT

         iii.     DOA's are replaced immediately by the Purchaser and must
                  receive highest repair priority by Manufacturer. Repaired DOA
                  units must be brought to "new" condition (boxes/labels/date
                  codes/etc) for restocking in Purchasers class A inventory.

         iv.      Manufacture will capture and summarize all warranty repair
                  data in a format that can be jointly used by the Manufacturer
                  and Purchaser to lead improvements in process, workmanship and
                  design to prevent future failures of the top Pareto failures.

                  Repaired Products shall be warranted for a period of ninety
                  (90) days or the remainder of the original warranty period,
                  whichever is longer. The aforementioned warranties shall inure
                  to Purchaser.

         Purchasers Products will be warranted by Manufacturer in accordance
         with the original manufacturers warranty or 90 days whichever is
         greater. In the event any components are not in conformity with those
         foregoing warranties, Manufacturer agrees to make commercially
         reasonable efforts to pursue failure analysis (root cause) data from
         the supplier and to negotiate on Purchasers behalf all warranty terms.

c        The foregoing warranty shall not be valid if the Products or component
         parts have been subjected to abuse or the defects are the result of and
         caused by misuse, accident, neglect, alteration, or improper testing,
         storage, and/or improper installation by Purchaser, it its agents,
         other subcontractors or its customers.

         identified the returned goods with the proper Returned Material
         Authorization (RMA) number displayed on the shipping cartons and the
         associated Product name. In addition, if there is more than one RMA lot
         being returned at any given time, there cannot be more than one RMA lot
         per shipping container. RMA numbers shall be issued by the Program
         Manager or designate.

         will be returned to Purchaser in new shipping containers with proper
         RMA number and Product name displayed on the carton. The period for
         this return will be thirty (30) calendar days from the date of receipt
         at Manufacturer.

         charge to cover the costs of handling and testing.

g.       Upon Purchaser's request, Manufacturer will repair out-of-warranty
         Products. Each such out-of-warranty repair shall be charged as agreed
         to by both Parties. This repair cost basis will be one of the

8.       TERMINATION AND CANCELLATION

a.       For Cause - This Agreement may be terminated by either party at any
         time upon occurrence of any one or more of the following Events of
         Default:

         (1)      failure of the other party: a) to perform pursuant to the
                  material terms and conditions of this Agreement; and b) to
                  cure such performance deficiency within thirty (30) days after
                  receiving written notice thereof given by the aggrieved party;
                  or

         (2)      the entering into or filing by the other party of a petition,
                  arrangement or proceeding seeking an order for relief under
                  the bankruptcy laws of the United States, a receivership for
                  any assets of the other party; a composition with or
                  assignment for the benefit of its creditors; a readjustment of
                  debt or the dissolution or liquidation of the other party.

b.       For Convenience - After the first year anniversary of the Effective
         Date, either party may terminate this Agreement for convenience upon
         one hundred eighty (180) days advance written notice to the other
         party. Should such termination occur, notwithstanding any implication
         to the contrary that may otherwise be suggested by this Agreement,
         neither party shall owe any obligation of any type whatsoever to the
         other party other than for accrued obligations existing as of the date
         of termination.

c.       Transition Support and Assurance - Manufacturer will support the
         transition to a new manufacturer and insure an adequate supply of
         Product to support reasonable Purchaser Forecasts during the transition
         period. If a supply disruption exceeding two weeks from confirmed
         delivery date or limitations of less than 75% of Purchaser's Forecast
         occurs due to the sole negligence or willful misconduct of Manufacturer
         and Manufacturer fails to cure such supply shortfall within thirty (30)
         days after receiving written notice thereof from Purchaser, the parties
         agree that damages will be difficult to ascertain and that

<PAGE>

                     ARRIS - PLEXUS MANUFACTURING AGREEMENT

         Purchaser's business will be irreparably damaged, as such Manufacturer
         will compensate Purchaser $1,000,000 as liquidated damages for the
         disruption. Such amount is payable within thirty (30) days of written
         notice by Purchaser of its claim for such amount due to such supply
         disruption. Purchaser will also provide such written notice to
         Manufacturer no later than 60 days after such supply disruption,
         failing which Manufacturer will be relieved of the reimbursement
         obligation. Prior to payment, Purchaser will provide the necessary
         documentation to support claims of supply disruption and a itemized
         detail of any out of pocket expense incurred.

         As mutually agreed in a transition plan, Manufacturer shall prepare,

         and shipping by Purchaser, each of the following items, to the extent
         (with respect to the items described in clauses a through d, below)
         such items are either owned by Purchaser or exclusively used in
         manufacture of the Products:

         a.       Product Documentation; e.g. drawings, schematics,
                  Bills-of-Materials, component specifications, approved
                  suppliers, test specifications, process files, and other items
                  necessary to describe the product.

         b.       Manufacturing Process Documentation; e.g. process profiles,
                  SMT placement programs, temperature profiles, control
                  parameters and other items necessary to describe the
                  manufacturing process.

         c.       Manufacturing and Test programs; software used in the
                  manufacture and test of the products.

         d.       Manufacturing and Test equipment, fixtures, jigs, transport
                  carriers and other items necessary to manufacture the product.

         e.       Materials, work in progress and Products.

         f.       Any consigned equipment described in Section 18 hereof and any

         Such removal shall be accomplished in a mutually agreed manner so as to
         reasonably minimize any disruptions. Items owned by Manufacturer (other
         than Materials and Products) shall be purchased by Purchaser at a price
         to be negotiated, not to exceed typical market prices. Purchaser shall
         also purchase all remaining Products (at then current prices) and
         Materials (as if such Materials were Excess Materials) and work in
         progress (at Manufacturer's cost at of the last completed manufacturing
         operation for such work in progress) and pay Manufacturer any costs
         associated with cancellation of Material then on order.

9.       INSPECTION

a.       Upon request and reasonable notice from Purchaser, Manufacturer shall
         allow Purchaser to inspect and review the work being performed under
         this Agreement, including Materials being used. However, shipments will
         not be delayed if Purchaser fails to effect such source inspection.
         Source inspection will not relieve Manufacturer of its warranty
         obligations herein.

                     ARRIS - PLEXUS MANUFACTURING AGREEMENT

b.       In the course of purchasing component parts on behalf of Purchaser,
         Manufacturer must follow Purchaser's Approved Vendors List (AVL) for
         all component parts. If Manufacturer offers an alternative to
         Purchaser's AVL, the alternative may be approved in writing by
         Purchaser prior to procurement/production at Manufacturer's facility
         which approval shall not be unreasonably withheld.

10.      ENGINEERING CHANGE ORDERS

It is recognized that from time to time Manufacturer will be asked to implement
Engineering Change Orders ("ECOs"). The following delineates the procedures to
be followed by the Parties:

a.       Purchaser must notify Manufacturer in writing of proposed ECO. This
         notification will include the documentation of the change to
         effectively support Manufacturer's investigation of the impact of this
         proposal. The documentation should include: ECO form with written
         description of change, revised BOM, drawings, AVL, media, required
         implementation date, etc.

b.       If such changes cause an increase or decrease in the total number of
         Products due under an order issued hereunder or in the time required
         for its performance, an equitable adjustment shall be made; provided,
         however, that any claim by either party therefore must be asserted in
         writing in the form of a quotation within thirty (30) calendar days
         from the acknowledged receipt date of the change notice by
         Manufacturer.

c.       Upon notice of a change, Manufacturer shall use commercially reasonable
         efforts to review all costs impacted within five (5) days after
         Manufacturer's receipt of ECO proposal. All cost impacts and material
         availability issues will be presented, mutually reviewed and agreed to
         in writing with Purchaser prior to Manufacturer's implementation.

d.       Purchaser will be responsible for all expedite costs associated with
         emergency ECO implementation. For non-emergency ECOs, Manufacturer
         shall present the cost impacts and material availability issues, to be
         mutually reviewed and agreed-to in writing by the parties prior to
         Manufacturer's implementation.

e.       Manufacturer shall notify Purchaser in writing of any proposed changes
         to the Products. If Purchaser has not given approval of any proposed
         changes within fifteen (15) calendar days after receipt of such written
         notification, Manufacturer will conclusively presume that Purchaser has
         disapproved the change. Manufacturer will continue to deliver unchanged
         Products in accordance with the provisions of this Agreement should
         Purchaser not approve the proposed change.

11.      CONFIDENTIALITY

Both parties acknowledge that, by reason of their relationship, they may have
access to certain information and materials concerning the other's business,

termination of this Agreement.

All written data such as drawings, plans, reports, designs, schematics, bill of
materials, and other specifications supplied by Purchaser to Manufacturer shall
remain the exclusive property of Purchaser. Such data and any copies thereof,
together with all data furnished by Purchaser and any copies thereof, shall be
returned to the extent requested upon completion of the services, in the event
of termination under the Agreement. The confidentiality obligations in this
paragraph shall be in addition to the confidentiality obligations in any
separate non-disclosure agreement between the parties. Should any conflict arise
between any such non-disclosure agreement and the provisions of this paragraph,
such non-disclosure agreement shall control.

12.      INDEMNIFICATION

Subject to Section 15.g hereof, Purchaser shall indemnify and defend the
Manufacturer against all claims, suits, losses, damages, expenses (including
attorneys' fees), and liabilities ("Claims") for bodily injury, personal injury,

indemnification rights hereunder shall notify the other party promptly upon
receiving or learning of any claim or action pursuant to which indemnity will be
sought and shall provide reasonable assistance to the indemnifying party, at the
indemnifying party's expense, in the defense of any such action. The
indemnifying party will have sole control over the defense or settlement of
claims indemnified by it. Other than with respect to intellectual property
infringement, both parties shall carry and maintain liability insurance coverage
to satisfactorily cover its obligations under this Agreement.

         approval.

b.       Cost reductions will be sought by Purchaser and Manufacturer for each
         Product through the terms of this Agreement. Manufacturer will revise
         pricing for each cost reduction as follows:

         (i)      Purchaser identified cost reductions will be reflected in the
                  pricing 100% after depletion of Materials.

         (ii)     50% of Manufacturer identified cost reductions will be
                  reflected in the pricing for ninety (90) days after depletion
                  of Materials, thereby sharing the cost reduction equally with
                  Purchaser. Thereafter, the full cost reduction will be
                  reflected in the base Material cost.

c.       Pricing will be reviewed and adjusted each calendar quarter by
         Manufacturer to reflect as a minimum: ECOs, present market conditions
         for material, cost reductions, present process yields, and changes in
         demand.

d.       Products depicted in Exhibit A will be priced as depicted in Exhibit G
         - Product Pricing. Product pricing will be revised from time to time as
         agreed by both parties.

a.       Upon prior authorization via a purchase order by Purchaser,
         Manufacturer shall order and purchase for Purchaser at Purchaser's
         expense all of the process tooling, assembly tools, and test fixtures
         required to manufacture the Products except for tools consigned by
         Purchaser and listed in Exhibit D ("Consigned Equipment"). Manufacturer
         shall submit the request for authorization to Purchaser in writing and
         Purchaser shall grant or deny the request in writing within ten (10)
         days after the date of request. If Purchaser does not

<PAGE>

                     ARRIS - PLEXUS MANUFACTURING AGREEMENT

         respond to Manufacturer within the prescribed period for each request,
         the request shall be canceled. Manufacturer shall not be liable for the
         impact to production schedules should Purchaser not grant authorization
         or should not respond to a request in a timely manner. All Purchase
         Orders and Forecasts for Products requiring the tooling shall be
         mutually reviewed and adjusted accordingly.

b.       Manufacturer shall provide or contract for all maintenance and
         calibration required for the process tooling, manufacturing tooling and
         test equipment whether purchased by Manufacturer or consigned by
         Purchaser while in the possession of Manufacturer. Preventative
         maintenance shall be at the expense of Manufacturer. Remedial
         maintenance and scheduled calibration required shall be at the expense
         of the Purchaser.

c.       Upon termination of this Agreement Manufacturer all of the process
         tooling, manufacturing tooling and test equipment paid for by Purchaser
         as well as all consigned tooling and equipment supplied by Purchaser
         shall be returned in the manner set forth in Section 8 of this
         Agreement.

19.      ARRIS CONSIGNED INVENTORY

a.       Manufacturer acknowledges that Purchaser may have inventory that will
         be consigned to Manufacturer. Manufacturer will warehouse free of
         charge Purchaser owned inventory. Beginning balance is established per
         part/quantity detail contained on Exhibit E hereto (such inventory, the
         "Consigned Inventory"). The list of Consigned Inventory shall be
         updated to reflect such inventory as of actual transfer date pursuant
         to a physical inventory of the Consigned Inventory to occur as mutually
         agreed by both parties (and Exhibit E shall be updated to reflect such
         changes).

b.       Consigned Inventory will be stored at the designated manufacturing
         facility. Manufacturer assumes risk of loss for the Consigned Inventory
         with the exception of loss due to spoilage, reduction in moisture
         content, and similar items and due to fire, flood, theft, Act of God or
         other casualties. Purchaser shall insure the Inventory from such
         casualties, and provide Manufacturer, upon request with proof of such
         insurance.

c.       Manufacturer will procure consigned inventory from Purchaser at
         Manufacturer's quoted cost, as required to support Purchasers Forecast
         and/or Purchase Orders. There will be monthly reporting on all
         transfers of the Consigned Inventory to Manufacturer's production
         inventory. Manufacturer will use commercially reasonable efforts to use
         products in the Consigned Inventory before purchasing from any other
         supplier. Material ending balances will be calculated and reported
         monthly.

d.       All book to physical adjustments of inventory records for whatever
         reason other than normal machine set-up and fallout will be the
         financial liability of Manufacturer. Any such book to physical
         consigned inventory discrepancy will be corrected by Manufacturer
         issuing Purchaser a credit for the quoted cost of those components.
