sale of network products Customer will offer Flextronics the best prices and
terms that it offers other customers for comparable projected volumes.

3.0  FORECASTS, PURCHASE ORDERS AND MATERIAL PROCUREMENT

3.1  FORECAST.  Each week, Customer shall provide Flextronics with a rolling six
(6) month Product order forecast, by week for the first thirteen (13) weeks and
monthly for the following three (3) months ("Forecast").

3.2  PURCHASE ORDERS.  Customer will issue Purchase Orders monthly for Products
to be manufactured in the subsequent four (4) month period commencing on the
date of the Purchase Order.  All Purchase Orders shall be submitted to
Flextronics at Flextronics' facility in either (i) Rochester, New Hampshire,
(ii) Limerick, Ireland, or (iii) any other Flextronics facility to which the
Parties mutually agree.  Purchase Orders shall be accepted by Flextronics,
provided however that Flextronics may reject any Purchase Order (i) if
Flextronics cannot reasonably obtain Materials necessary to fulfill a Purchase
Order; (ii) if new and unique equipment is required to manufacture the Products;
or (iii) if a Purchase Order in the aggregate exceeds the most recent Forecast
by 10% for the first month, 20% for the second month, or 30% for the third
month. Flextronics shall notify Customer of its rejection of any Purchase Order
within five (5) Business Days of receipt of such order in writing, specifying
the reason for its rejection and proposing reasonable alternatives.

3.3  The Parties agree that the terms and conditions contained in this Agreement
shall prevail over any terms and conditions of any Purchase Order,
acknowledgment form or other instrument.

3.4  Each accepted Purchase Order constitutes:  (i) a commitment by Flextronics
to manufacture the Products described in that Purchase Order; and (ii) an
authorization from the Customer to Flextronics to procure, using standard
purchasing practices, the Materials and labor necessary to manufacture the
Products covered by that Purchase Order.

3.5  In addition, Customer authorizes Flextronics to purchase, in amounts beyond
the amount necessary to fill accepted Purchase Orders, labor and Materials:  (i)
with lead times greater than ninety (90) days at the time the Purchase Order is
placed ("Long Lead Time Components") plus 30 days to account for the order,
shipment, receipt and manufacturing time and,  (ii) purchased in quantities
above the required amount for accepted Purchase Orders to achieve price targets
("Economic Order Inventory"), and (iii) purchased in excess of requirements for
accepted Purchase Orders because of minimum lot sizes available from
manufacturers ("Minimum Order Inventory").  Together these are called "Special
Inventory".  Flextronics may purchase Long Lead Time Components sufficient to
meet all deliveries under the Purchase Orders and Product Forecast in effect at
the time the order with the supplier is placed, and may reasonably purchase
Minimum Order Inventory even if greater than the amount necessary to meet
Purchase Orders and Product Forecast.  Economic Order Inventory shall be
purchased by Flextronics only with the prior approval of Customer.  Flextronics
will, from time to time, hold Long Lead Time Components and finished Products in
inventory to increase Customer's sourcing flexibility. The components and
quantities of all such inventory will be documented in a separate letter and
signed by authorized representatives of both Flextronics and Customer.

4.0  SHIPMENTS, SCHEDULE CHANGE, CANCELLATION

4.1  SHIPMENTS.  All Products delivered pursuant to the terms of this Agreement
shall be suitably packed for shipment in accordance with Customer's Packing
Specifications, marked for shipment to Customer's distribution center, or other
agreed location, and delivered to a carrier or forwarding agent.  Shipment will
be F.O.B. Flextronics' facility at which time risk of loss and title will pass
to Customer.  All freight, insurance and other shipping expenses, as well as any
special packing expenses not included in the price for the Products, will be
paid by Customer. If the Product is source inspected by Customer prior to
shipment, Customer will inspect goods within five (5) Business Days of its
request date.

</TABLE>

All other changes in quantity or shipment date require Flextronics' prior
written consent.  Flextronics shall use reasonable commercial efforts to meet
quantity increases.  Allowable quantity increases are subject to Materials
availability.  If there are extra costs to meet a reschedule or increase,
Flextronics will inform Customer for its acceptance and approval in advance.  In
order to minimize excess and obsolete inventory or to respond to End Customer
requirements, Customer shall have the right to split Purchase Orders or schedule
partial deliveries.

4.3  CANCELLATION.  If Customer cancels any portion of Product quantity of an
accepted Purchase Order, Customer will pay Flextronics for Products, Inventory,
and Special Inventory affected by the cancellation as follows:  (i) 100% of the
contract price for all Product Inventory in Flextronics' possession, (ii) 104%
of the cost of all Manufacturing Inventory and Special Inventory in Flextronics'
possession and not returnable to the vendor or usable for other customers,
whether in raw form or work in process, less the salvage value thereof, (iii)
104% of the cost of all Manufacturing Inventory and Special Inventory on order
and not cancelable, (iv) any vendor cancellation charges incurred with respect
to Manufacturing Inventory and Special Inventory accepted for cancellation or
return by the vendor, and (v) expenses incurred by Flextronics related to labor
and equipment specifically put in place to support Customer's Purchase Orders
which expenses have been approved by Customer.  Flextronics will use reasonable
commercial efforts to return unused Manufacturing Inventory and Special
Inventory to and to cancel pending orders for such inventory with its supplier,
and to otherwise mitigate the amounts payable by Customer. Customer may, at its
option, instruct Flextronics to ship, at Customer's expense, all or any portion
of any Manufacturing Inventory or Special Inventory for which Customer has paid
Flextronics to any location designated by Customer.  Flextronics will notify
Customer within five (5) Business Days of receipt of a cancellation if Customer
will be charged any fees for a cancellation, and the Parties agree to cooperate
in trying to reduce any such charges.

5.0  INVENTORY MANAGEMENT, DELIVERY AND ACCEPTANCE

5.1  PRODUCT INVENTORY MANAGEMENT.    Flextronics will maintain and manage
Customer's Product Inventory so as to accommodate Customer's Forecast and to
provide a Product Inventory buffer at no additional charge.  For any Product
Inventory maintained and managed by Flextronics in excess of Customer's Forecast
and the Product Inventory buffer because of Customer's failure to take delivery
of Product in accordance with its forecast, Customer shall pay Flextronics an
inventory fee of one (1%) percent of the Product price for two four-week periods
and one five-week period during each Quarter, starting on the Effective Date.
During each four or five week period, the inventory fee for each Product shall
be based upon Customer's most recent Forecast and calculated as follows:  (a)
the weekly average of

                                    8 of 23
<PAGE>

                                                                  EXECUTION COPY

that forecasted amount will be taken, and that amount multiplied by the number
of weeks in the Inventory Buffer Period to determine the maximum Product
Inventory level, or Inventory buffer, for each week for each Product; (b) at the
end of each week, the actual inventory held by Flextronics will be compared to
the Inventory buffer for the week; (c) at the end of the four-week or five-week
period, the difference between the actual inventory counts and the Inventory
buffer for each Product at the end of each week are added together and, if the
sum is a positive number, it is divided by the number of weeks in the period to
determine the number of excess units of that Product; and (d) for each Product
where the actual inventory exceeds the Inventory buffer, Customer shall pay
Flextronics an inventory fee equal to one (1%) percent of the product of the
excess units of that Product times the Product price [.01(excess units x unit
price)]. A further illustration of this calculation is attached as Exhibit B.
The sum of all inventory fees shall be payable by Customer net thirty days from
the last day of each four-week period or five-week period.

5.2  AGED PRODUCT INVENTORY.  Upon five (5) Business Days notice to Customer
that Flextronics has held any Product Inventory for more than ninety (90) days,
Flextronics may deliver such Product Inventory to Customer.

5.3  DELIVERY.  Flextronics shall deliver Products to the Customer distribution
center, or other agreed location, on the date specified in the applicable
Purchase Order.  Flextronics shall promptly notify Customer of any expected
delays in meeting the delivery dates specified in each Purchase Order.  Customer
shall have the right to request an expedited shipment of affected Products, and
Flextronics shall bear all incremental freight costs associated with the
expedited shipment.

5.4  ACCEPTANCE.  The Parties agree that the Products shall be deemed accepted
upon delivery to Customer's facility.

include a description of the proposed engineering change sufficient to permit
Flextronics to evaluate its feasibility and cost. Flextronics shall use
reasonable efforts to provide within five (5) days of receipt of an ECO a
detailed response to the ECO including a specification of: (a) material exposure
for scrap (Material procured and no longer usable); (b) material cost for new
Material to be added; (c) labor cost by activity to be performed; (d) the
proposed implementation date; and (e) the impact on the delivery schedule and
pricing of the Product.  Neither Party shall unreasonably withhold or delay
agreement to an ECO and the Parties shall use all reasonable efforts to agree
to, and implement at the earliest opportunity, ECO's relating to personal and
Product safety.  Until an ECO has been agreed to in writing, such ECO shall not
become effective, and the Parties shall continue to perform their obligations
under the then-effective specifications.

6.2  FLEXTRONICS SPONSORED CHANGES.  Flextronics may notify Customer in writing
of proposed ECOs no less than the lead time of the affected Materials plus
thirty (30) days and will, if so requested, provide Customer with samples.  The
notification shall include the proposed Product changes, anticipated price
changes and the proposed implementation date.  Notification shall also include
the appropriate documentation to support Customer's investigation of the impact
of this proposal. Customer will review the feasibility of the implementation of
the proposed ECO.  If lead time or new costs are required for the ECO, lead time
and new prices will be reviewed. Customer is to advise Flextronics of its
decision with respect to the proposed ECO within ten (10) Business Days after
receipt of Flextronics' written notification. No ECO's shall be made by
Flextronics without Customer's prior written approval, which may be withheld in
Customer's sole discretion.

which is attached as Exhibit C.  Before implementing any such schedule, the
Parties agree to review and adjust Non-Labor Overhead, standard Product pricing
and the new product services pricing schedule to ensure that Customer is not
charged twice for such services and that the new product services pricing is
industry competitive.  When Customer, in Customer's discretion, determines that
the Volume Shipment Date for a proposed new product has been achieved, that new
product shall be considered a Product under the terms of this Agreement and all
provisions applicable to the manufacture of any Product, including by not
limited to pricing terms and Flextronics' warranties, shall thereafter apply to
the manufacture of that Product, unless the Parties agree otherwise.

                                                                  EXECUTION COPY

  Customer is late with payments, or Flextronics has reasonable cause to believe
  Customer may not be able to pay, Flextronics may require prepayment or delay
  shipments or suspend work until assurances of payment satisfactory to
  Flextronics are received.

12.2  INITIAL PRICING.  Prices for all Products delivered to Customer during the
Initial Quarter shall be calculated as follows:

          For Products manufactured by Flextronics in the United States:

               Initial Price = (BOM Value at Closing + Initial Overhead) x .944

          For Products manufactured by Flextronics in Ireland:

               Initial Price = (BOM Value at Closing + Initial Overhead)

The Initial Price for all Products is included in Exhibit A.

12.3  QUARTERLY PRICE ADJUSTMENTS.  Until the expiration of the initial term of
this Agreement, prices for all Products delivered under this Agreement shall be
adjusted at the beginning of each Quarter after the Initial Quarter, with the
adjusted price for each Product calculated as follows:

          Adjusted Price = (Repricing BOM Value + Adjusted Overhead) x  100/95

provided that the Adjusted Price for each Product price shall never exceed the
price for that Product in the prior Quarter, except to the extent that a higher
price results because of market forces affecting the BOM Value that can be
confirmed by independent industry benchmarks.   Flextronics shall notify
Customer of its proposed Adjusted Price for a Quarter fifteen (15) days before
the beginning of the Quarter (the "Repricing Notice").  Customer may require
Flextronics to explain or provide documentation in support of the proposed
Adjusted Price before the Quarterly Review Meeting, and the Parties shall
negotiate in good faith any differences regarding the Adjusted Price for a
Quarter at the Quarterly Review Meeting.  The Adjusted Prices finally agreed to
by the Parties shall apply to all Products delivered by Flextronics to Customer
during that Quarter.  An example calculation of the Adjusted Price for a Product
is attached as Exhibit D.

12.4  VOLUME PRICE ADJUSTMENTS. The Parties agree that if in any Quarter after
the Initial Quarter the total unit volume of Products delivered to Customer and
the total Standard Hours used to manufacture such Products:

  (a) both decline to more than ten percent (10%) below the total unit volume of
  Products manufactured and the total Standard Hours used to manufacture such
  Products in the Initial Quarter, the Parties shall meet and negotiate in good
  faith increases in future Product prices or other mechanisms to compensate
  Flextronics for the underabsorbtion of Flextronics' manufacturing overhead
  expenses caused by the decline and not covered by product purchases by other
  customers; or

  (b) both increase to more than ten percent (10%) above the total unit volume
  of Products manufactured and the total Standard Hours used to manufacture such
  Products in the Initial Quarter, the Parties shall meet and negotiate in good
  faith reductions in future Product prices to provide Customer with the benefit
  of the overabsorbtion of Flextronics' manufacturing overhead expenses caused
  by the increase.

12.5  PAYMENT AT CLOSING.  Within thirty (30) days of the Effective Date,
Customer shall pay Flextronics an amount equal to fifty percent (50%) of:   (a)
the aggregate of the actual Bill of Materials values for all Products delivered
by Customer to End Users between December 21, 1999, and the Effective Date;
subtracted from (b) the aggregate Bill of Materials values for such Products
calculated using the BOM Value as of December 21, 1999.

12.6  PRODUCT PRICE SAVINGS REBATE.  Following the close of every Rebate Period,
a Product price savings rebate shall be computed and invoiced to Customer.  The
rebate for a particular Rebate Period shall equal that Rebate Period's Rebate
Share multiplied by the difference between (a) the total value of all Products
delivered to Customer in the Rebate Period and (b) the total value of those
Products had Customer paid (i) in the First Rebate Period, the Initial Price for
those Products, or (ii) in the subsequent Rebate Periods, the price in effect
for those Products on the day before the first day of the Rebate Period.
Customer agrees to pay any rebate within thirty (30) days of receipt of an
invoice for the rebate.  An example of such a calculation is shown in Exhibit G.

12.7  OPERATING PROFIT REBATE. Within thirty (30) days of the first anniversary
of the Effective Date, Flextronics shall pay to Customer the amount of
Flextronics' Operating Profit for that year that exceeds five percent (5%) of
Net Sales for that year.

12.8  DISCLOSURE OF COST INFORMATION.  Flextronics shall, subject to any
relevant obligation of confidentiality, provide to Customer all information and
documentation reasonably required by Customer with respect to  BOM Value and
Materials costs.  Flextronics shall provide reasonable assurances to Customer
that it is receiving the lowest cost for Materials charged by Flextronics to
other similarly situated customers (based on volume, types of  products and
Materials, level of variance between forecasts, actual demand, manufacturing
facility used, and other criteria to be mutually agreed upon).

12.9  Right to Review.   Customer shall, at its cost and expense, have the right
exercisable on a Quarterly basis upon ten (10) days' notice to Flextronics
during Flextronics' normal business hours to review Flextronics' books and
records relating to BOM Value and Materials costs and, for new products being
considered for manufacture under this Agreement pursuant to Section 7.1, Labor
Cost and Non-Labor Overhead, for the purpose of confirming those costs and the
pricing methodology for the Products and all fees or charges payable.  If
Customer identifies any issues or concerns related to such costs and the
determination hereunder of any price or fee, Customer shall provide a statement
to Flextronics setting out in reasonable detail the nature of such issues or
concerns.  The Parties shall attempt to resolve the matters in dispute in a
timely manner and make such adjustments, if any, to any price or fee as may be
required. For certainty, Customer acknowledges and agrees that any right to
review under this Section 12.9 may be limited by and is subject to any
confidentiality obligations that Flextronics may have to its other customers.

21.0    CONFIDENTIAL INFORMATION

21.1    CONFIDENTIAL INFORMATION.  "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"; (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, Customer's Confidential Information
shall include without limitation all Manufacturing or Functional Specifications
of a Product, all Product order Forecasts, and all new product plans.

21.2    CONFIDENTIAL INFORMATION EXCLUSIONS.  Confidential Information does not
include information that the Receiving Party can demonstrate is: (i) now or
hereafter, through no fault of the Receiving Party, in the public domain; (ii)
known to the Receiving Party from a source without an obligation of
confidentiality to the Disclosing Party; (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

                                    20 of 23

                                                                  EXECUTION COPY

any government agency or court; provided, however, that before any such
disclosure, the Receiving Party shall (a) assert the confidential nature of the
Confidential Information; (b) immediately notify the Disclosing Party in writing
of the 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.

21.3  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 care 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.  The
Receiving Party shall have appropriate written agreements with any such
employees or contractors sufficient to comply with the provisions of this
Agreement.

21.4  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 (vi) in
confidence, in connection with a merger or acquisition or proposed merger or
acquisition, or the like.

21.5  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.

22.0    MISCELLANEOUS

22.1   COMPLIANCE WITH THE LAWS AND PERMITTING.  Each Party agrees that its

22.2  ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement between

or warranties on behalf of any other Party, whether express or implied, or to
bind the other Party in any respect whatsoever.

22.5  DISPUTE RESOLUTION.  In the event of any dispute or disagreement with
regard to the rights or obligations of the Parties under this Agreement or any
transaction contemplated by it, the Parties shall use all reasonable efforts to
settle the dispute or disagreement.  If their initial efforts are unsuccessful,
either Party may, upon written notice to the other, escalate the dispute or
disagreement for review and discussion between their chief executive officers.
The Parties agree that, except in the case of an action for preliminary relief
to enjoin an infringement of an Intellectual Property Right or any other event
that may cause irreparable injury, neither Party shall institute litigation with
regard to any dispute or disagreement until at least thirty (30) days after the
date of the notice escalating the dispute or disagreement to their chief
executive officers.  In the event a dispute between the Parties hereunder with
respect to this Agreement must be resolved by litigation or other proceeding or
a Party must engage an attorney to enforce its rights hereunder, the prevailing
Party shall be entitled to receive reimbursement for all associated reasonable
costs and expenses (including, without limitation, attorneys' fees) from the
other Party.

22.6  CHOICE OF LAW AND JURISDICTION.  Any action brought by Customer under this
Agreement or with regard to actions taken pursuant to this Agreement shall be

California, notwithstanding any contrary conflict of law or choice of laws
principle, and shall be brought and maintained exclusively in the state or
federal courts of the State of California.  Any action brought by Flextronics
under this Agreement or with regard to actions taken pursuant to this Agreement

federal courts of the State of New Hampshire.

22.7  SUCCESSORS, ASSIGNMENT.  This Agreement shall be binding upon and inure to
the benefit of the Parties hereto and their respective successors, assigns and
legal representatives.  Neither Party shall have the right to assign or
otherwise transfer its rights or obligations under this Agreement except with
the prior written consent of the other Party, not to be unreasonably withheld.
Nothing in this section shall prohibit Customer from:  (i) transferring rights
and obligations under this Agreement to its Affiliates provided that such
entities agree to be bound by the terms and conditions of this Agreement; or
(ii) transferring its rights and obligations under this Agreement to another
entity that purchases all or substantially all of Customer's business,
regardless of the nature of that transaction, so long as that entity agrees to
be bound by the terms and conditions of this Agreement.

22.8    FORCE MAJEURE.  In the event that either Party is prevented from
performing or is unable to perform any of its obligations under this Agreement
(other than a payment obligation) due to any Act of God, fire, casualty, flood,
earthquake, war, strike, lockout, epidemic, destruction of production
facilities, riot, insurrection, or any other cause beyond the reasonable control
of the Party invoking this section, and if such Party shall have used its
commercially reasonable efforts to mitigate its effects, such Party shall give
prompt written notice to the other Party, its performance shall be excused, and
the time for the performance shall be extended for the period of delay or
inability to perform due to such occurrences.  Regardless of the excuse of Force
Majeure, if such Party is not able to perform within ninety (90) days after such
event, the other Party may terminate the Agreement and the provisions of Section
15.4 shall apply.  Termination of this Agreement shall not affect the
obligations of either Party, which exist as of the date of termination.

      material furnished by Riverstone which is deemed confidential hereunder

13. INTELLECTUAL PROPERTY CLAIMS:

13.1  INDEMNIFICATION BY RIVERSTONE - Riverstone shall defend, at Riverstone's
      expense, any claim brought against Tellabs, its Resellers or End Users (a
      "Claim Defendant") alleging that any Riverstone Product acquired or
      licensed under this Agreement (or the underlying technology) infringes a
      patent, copyright, trade secret, mask work right or any other intellectual
      property right (hereinafter a "Claim"). Riverstone shall pay all costs and
      damages awarded or agreed to in settlement, provided that the Claim
      Defendant gave Riverstone prompt written notice of the Claim, reasonable
      assistance and sole authority to defend or settle the Claim. Riverstone
      shall obtain for the Claim Defendant, the right to continue using the
      Product, or replace or modify the Product so it becomes non-infringing. If
      the remedies set forth in the preceding sentence are not reasonably
      available, Riverstone shall grant Tellabs a credit for the Product

                                     Page 9
<PAGE>

      normally depreciated and have Tellabs return the Product to Riverstone.
      Riverstone shall not have any liability if the alleged infringement is
      based upon the use, license or sale of the Product in combination with
      other products, including software not furnished by Riverstone if the use,
      license or sale of the Product alone would not have constituted an
      infringement. This is Riverstone's entire liability and Tellabs exclusive
      remedy for intellectual property Claims.

13.2  REPRESENTATION AND INDEMNIFICATION BY TELLABS - Tellabs represents and
      warrants that it is the owner or licensee of all Tellabs Brands and agrees
      that Riverstone shall have no responsibility for the protection or
      maintenance of Tellabs' rights in Tellabs Brands, provided that Riverstone
      has used the Tellabs Brands only in strict compliance with the terms of
      this Agreement. Tellabs shall hold Riverstone harmless from and defend, at
      Tellabs' expense, any claim brought against Riverstone alleging that any
      Tellabs Brand infringes the trademark, trade name or any other
      intellectual property right of a third party (a "Brand Claim") provided
      that Riverstone's use of the Tellabs Brands was in strict conformity with
      the terms of this AGREEMENTS. Tellabs shall pay all costs and damages
      awarded or agreed to in settlement, provided that the Riverstone gave
      Tellabs prompt written notice of the Brand Claim, reasonable assistance
      and sole authority to defend or settle the Brand Claim. Riverstone shall
      not be entitled to use or distribute the Tellabs Brands or any product
      bearing any of the Tellabs Brands except to Tellabs.

                    EXHIBIT D - TECHNICAL SUPPORT GUIDELINES

NATURE OF TECHNICAL SUPPORT - During the term of this Agreement, Riverstone will
assist TELLABS in the identification and resolution of Product performance
problems and errors.  Riverstone's technical support shall be Level 3 Support
to the TELLABS in connection with its support of its Resellers and End Users.
Level 1 Support and Level 2 Support shall be the sole and exclusive
responsibility of the TELLABS and its Resellers.  Level 3 Support shall be
provided by Riverstone only to engineering personnel designated by the TELLABS
who are trained in the technical operation of the Product.  Riverstone's support
will be provided in accordance with the following guidelines:

1.   TECHNICAL SUPPORT

1.1  Availability - Riverstone shall provide Level 3 Support via telephone,
     facsimile and electronic mail twenty-four hours per day, seven days per
     week.

1.2  Response - TELLABS shall use reasonable efforts to attempt to resolve End
     User support requirements for the Products. If TELLABS cannot successfully
     resolve an issue within a reasonable period of time, Riverstone's technical
     support staff will provide assistance. Riverstone will provide an initial
     response to all TELLABS support requests within [ * ] (unless an earlier
     response is required by Section 2 below), and TELLABS and Riverstone will
     mutually agree, in good faith, what additional information or documentation
     will be required for resolution of the problem. Riverstone will provide a
     problem report form for TELLABS's use in reporting problems.

2.   ERROR CORRECTION

2.1. Error Definitions - "Error" means a reproducible that causes a Product not
     to function substantially in conformance with its specifications. Errors
     are classified as follows:

     Category 1: End User's network segment or management application is down or
     experiencing a consistent, measurable performance impact with no immediate
     resolution available.
     Category 2: End User is experiencing intermittent failure, performance
     degradation, or functionality of network or management applications.
     Category 3: Issues that do not affect customer's normal network or
     management application operation or questions concerning Product
     functionality or usage.

2.2. Non-Emergency Technical Support - For End User or Reseller problems not
     deemed by TELLABS to be an emergency, Riverstone will use its best efforts
     to address and resolve the problems as quickly as practicable during normal
     business hours. If a particular problem is not resolved within two (2)
     Business Days following the initial call to Riverstone, technical support
     managers and engineers for each Party, will discuss and work in good faith
     to devise and implement a satisfactory resolution. Problems regarded as
     non-emergencies include: (i) installation and operation problems, i.e.
     routine questions that can be resolved by following documentation; and (ii)
     deviations from documentation, omissions and known workarounds, i.e.
     problems that cannot be resolved by following the documentation or result
     from reasonable misinterpretation of the documentation.

2.3. Emergency Technical Support - Riverstone acknowledges that Category 1 and
     Category 2 Errors should be resolved quickly. During the applicable
     Warranty Period, Riverstone shall replace any defective Products or correct
     Errors promptly following receipt of notice from TELLABS, not to exceed the
     following:

     . Riverstone shall provide an initial response to Errors reported by
       TELLABS within [ * ] (Category 1) and within [ * ] (Category 2 and 3) and
       TELLABS and Riverstone shall promptly agree in good faith to any
       additional information and documentation that may be required to permit
       Riverstone to resolve such errors. The error correction period begins
       after TELLABS has enough information to profile the error and can
       recreate the error or has access to a facility where the error can be
       recreated. Initial response is defined as talking to a qualified Level 3
       support engineer who initiates trouble-shooting.

     . Riverstone shall use its best efforts to resolve Category 1 Errors within
       [ * ] of receipt of notice of such Error.

     . Riverstone shall use its best efforts to resolve Category 2 Errors within
       [ * ] of receipt of notice of such Error.

     . Riverstone shall use its best efforts to resolve Category 3 Errors within
       [ * ] of receipt of notice of such Error.

                                    Page 20
<PAGE>

      The prescribed Error correction periods above may be extended by agreement
      of the Parties, e.g., if resolution of problem requires hardware
      certification or test, or if resolution represents significant risk to the
      primary Product functions.

2.4.  Support Reports and Evaluation - Riverstone shall provide a reporting
      mechanism by which TELLABS will regularly receive a detailed list of the
      status of all Errors reported and resolved, including a list of
      workarounds and bug-fixes. At least once during each calendar quarter, the
      Parties shall hold management-level meetings to discuss improvements in
      support.

3.    TECHNICAL SUPPORT HOTLINE

TELLABS shall make all requests for technical support to the following hotline
telephone or facsimile number, or via the Internet to the address indicated:

  Riverstone Technical Hotline contacts as follows:
  Telephone No.  877 -RSN-TAC9

                                   Exhibit G
                           Process for Modifications

    In the event of any conflict between the terms of this Exhibit G and the
    terms of Section 4.3 of the Agreement the terms of this Exhibit G will
    control.

1.  Representatives from Riverstone and Tellabs (the "Product Committee") agree
    to meet at the beginning of each calendar quarter during the term hereof to
    discuss new features to be added to the Products and to modify the Product
    Roadmap which will guide the development of the Products. The initial
    Product Roadmap is attached as Exhibit F.

2.  Tellabs shall have the right to develop new line cards for the Products,
    other than a [ * ], that are [ * ]. Nothing will prohibit Tellabs from
    independently developing a CMTS product or card (but not for integration
    into the Product) provided that Tellabs does not use any Riverstone
    confidential or proprietary information in such development.

3.  Riverstone, either itself or through a third party, will [ * ] requested by
    Tellabs, except those which Tellabs has elected to develop pursuant to
    paragraph 2 above. Riverstone will notify Tellabs within 60 days of the date
    the Product Committee submits the feature to Riverstone [ * ]. If Riverstone
    [ * ], either itself or through a third party, the [ * ] be owned by
    Riverstone, and subject to paragraph 4 below, Riverstone will be free to
    make the [ * ]. If Riverstone does not [ * ] within the 60 day period, then
    Tellabs can:

    (i)  If the feature is a software feature, [ * ]. This software feature will
         not be sold to any other customer for [ * ] after general availability
         of the feature, provided however that if [ * ] takes 6 or more months,
         the period [ * ] will be one (1) year. This software feature will [ * ]
         by Riverstone and Tellabs.

    (ii) If the feature requires a new line card, [ * ]. This line card will
         [ * ]. Nothing will prohibit Riverstone from independently developing a
         comparable or equivalent feature or line card provided that Riverstone
         does not use any Tellabs confidential or proprietary information in
         such development.

4.  Certain of the features requested by Tellabs may contain Tellabs proprietary
    intellectual property, trade secrets or confidential information or
    functionality not found in the products of any other competitor (each, a
    "Unique Feature"). If Riverstone develops this feature pursuant to the
    foregoing paragraphs, either independently or with the assistance of Tellabs
    or a third party, the feature may be incorporated by Riverstone into the
    relevant Products and [ * ] during the term of the Agreement, Tellabs may
    specify that the license to Riverstone is subject to [ * ] Riverstone from
    selling any product that embodies or utilizes the feature to [ * ] from the
    date the product is first made generally available to Tellabs. Riverstone
    acknowledges that there may be situations in which Tellabs wishes to
    incorporate a Unique Feature in the Product and believes it needs [ * ]. In
    such cases, Tellabs will notify Riverstone that this situation exists when
    the feature is first presented to the Product Committee and before any
    confidential information regarding the nature, purpose, functionality or
    other attributes of the Unique Feature is disclosed to any Riverstone
    employee or representative. The parties will engage in good faith
    negotiations regarding such additional protections.

5.  The restriction contained on Riverstone's right to sell a feature to a CMTS
    customer under Section 3 (i) above and the field of use restriction
    contained in the license from Tellabs to Riverstone under Section 4 above
    shall expire automatically on the date that [ * ].

6.  Riverstone will provide to Tellabs such assistance and information (such as,
    interface information) which is necessary for Tellabs to exercise the
    development and other rights set forth above and in the Agreement, and shall
    grant to Tellabs and hereby grants to Tellabs an fully paid up, worldwide
    license to use such information and technology for the purpose of exercising
    such rights.
