In support of its ongoing efforts to improve product performance, process
efficiency and reduce the costs of Processing Products, Byers Peak may from time
to time suggest that an engineering change be made to a Product by delivering a
proposal to VNUS. Each proposal shall include a description of the proposed
change, a description of any improvements in the Product or cost reductions
which will result from the change, and the effect of the change, if any, on
production scheduling or Product testing. Each proposal shall provide detail
sufficient to permit VNUS to evaluate the desirability of such change. VNUS
agrees to consider each proposal it receives from Byers Peak, but reserves the
right to accept or reject each such proposal in its sole discretion.

In the event either VNUS or Byers Peak identifies an engineering change that
must be implemented for reasons of safety or efficacy, the parties agree to
cooperate so as to effect such a change as soon as possible after discovery.
Once the need for such a change is discovered, the parties agree that no
affected Product shall be Processed or shipped until such a change has been
implemented, notwithstanding any delay in scheduled ship dates. The parties
further agree to cooperate in the implementation of such a change on Product
shipped prior to discovery of the hazard. In this regard, Byers Peak agrees to
provide a field and factory retrofit method (including materials and/or labor),
as appropriate, including spares. VNUS and Byers Peak shall agree in writing on
appropriate charges for the implementation of a change prior to each change
implementation.

Byers Peak agrees to provide VNUS such method at rates noted in Exhibit A, with
all assistance required to develop and release such methods at the engineering
rate of $***/hour.

VNUS and Byers Peak agree to determine if the change directly impacts material
or labor costs. If such a change results in a Product modification, and cost is
impacted, the price of the units will be adjusted, Amendments to Exhibit A and
outstanding purchase orders will also be made in accordance to the requirements
set forth in this contract.

acts of God, acts of civil or military authority, fires, floods, epidemics,
quarantine restrictions, war, riots, accidents to machinery, acts of terrorism,
or any other like or different events beyond the control of the party whose
performance is interfered with. In any such case, prompt written notice shall be

        information.

     2. Suppliers initially involved in RBC's quote process for fabricated
        assemblies were used to determine material costs in this proposal.
        Byers Peak will review the utilization of other suppliers if/when it
        becomes appropriate for improvements in cost, quality and delivery.

     3. Byers Peak's quality system will be utilized for any validations
        required, DMR structure and the production of this product.

     4. Customer and or RBC (tbd) will provide direction for, and participate
        in, sustained engineering efforts for product and process as required:

          a.  Change-order review and approval process

          b.  Review and approval of planning and risk mitigation

          c.  Product configuration release (DMR)

          d.  Configuration change review and approval

     5. Patent requirements are not within the scope of Byers Peak's
        responsibilities.

     6. NRE estimate is based on the assumption that a Device Master Record
        exists in a complete structure and is available to Byers Peak in
        electronic format.

     7. Product certification efforts, such as UL, CE, ASTM ship qualifications
        are not included.

     8. Our proposal to address the current inventory of materials at RBC is to
        transfer these materials to Byers Peak with no carrying cost applied.
        Depending on inventories, Material Purchase Orders will either be
        issued to RBC for the entire stock of materials or as materials are
        needed for product build. Materials will be purchased at RBC's "last
        paid" pricing.

BUSINESS DETAILS

The costs associated within this proposal are three-fold:

1)  NRE efforts will begin once Byers Peak receives an approved copy of this
    proposal and a purchase order for the amount noted in the NRE section. The
    purchase order should be indicated with a "not to exceed" amount.

2)  Production will begin once a second purchase order is received and a Supply
    Agreement has been approved.

      NOTE:

      A minimum build of *** units is required to attain acceptable quantities
      for process validation per Byers Peak's current quality system [should RBC
      request such validation].

      Byers Peak acknowledges that a different quantity may be required to
      satisfy RBCs' Quality System requirements.

3)  If desired, Repair Depot services will require a separate purchase order.

ESTIMATED LEAD-TIME

First Article: *** from the time Byers Peak has taken receipt of all
documentation, materials and capital equipment. Product lead-times are based on
current supplier quoted delivery lead-times.

Production volumes can begin upon customer First Article sample approval.

TERMS

NRE Payment terms are net ***.

Product Payment and Repair Depot terms are ***.

Should client opt to cancel or modify the program, they will be invoiced for
work performed and equipment & materials committed (not to exceed purchase
order quantity).

INTRODUCTION

Byers Peak, Inc. is submitting a second revision of the manufacturing
proposal. This document is intended to capture the estimated product cost that
is based on an updated product structure and Bill of Material.

Quote is based on request for second quote email dated January 15, 2004 from
Chirs Justice of RBC and referencing file: Second_Quote_Package.zip.

PROJECT SUMMARY

OBJECTIVE

To provide finished VNUS RF Generator units that meet the following:

     -  Specification
     -  Cost target
     -  Timely delivery requirements, including scalable production
     -  Flexibility in monthly forecasted volumes
     -  Depot repair service (if requested)
     -  Regulatory/quality preparedness

SCOPE OF WORK
     -  The NRE scope of this manufacturing project is yet to be determined. NRE
        activities may include but are not limited to: internal costs for
        engineering efforts to transfer/supplement the Design History File and
        Device Master Record, external efforts associated to Circuit Card
        Assembly set-up and test processes/fixtures. CCA Test approaches are
        still in discussion (flying probe verses ICT (in-circuit test), etc.).

PROPOSAL DELIVERABLES

Byers Peak is providing the estimated cost associated to materials, assembly,
test and margin for the VNUS RF Generator:

MANUFACTURING TRANSFER AND MANUFACTURING NRE

The elements associated with product transfer responsibilities will be
allocated to RBC, VNUS or Byers Peak, Inc. As the definition of these
responsibilities is refined, another iteration of this proposal will be
submitted.

ASSUMPTIONS/NOTATIONS

   1. The Bill of Materials provided by RBC was utilized for device material
      estimates and the accuracy of the material cost is based on this
      information.

   2. Suppliers initially involved in RBC's quote process for fabricated
      assemblies were used to determine material costs in this proposal. Byers
      Peak will review the utilization of other suppliers if/when it becomes
      appropriate for improvements in cost, quality and delivery.

   3. Our proposal to address the current inventory of materials at RBC is to
      transfer these materials to Byers Peak with no carrying cost applied.
      Depending on inventories, Material Purchase Orders will either be issued
      to RBC for the entire stock of materials or as materials are needed for
      product build. Materials will be purchased at RBC's "last paid" pricing.

   4. A minimum build of *** units is required to attain acceptable quantities
      for process validation per Byers Peak's current quality system [should RBC
      request such validation]. Byers Peak acknowledges that a different
      quantity may be required to satisfy RBCs' Quality System Requirements.

cost-effective repair depot services.

-  Optional Post-Warranty Repair and Complaint Investigation rates are $*** hour
   for labor plus materials with *** margin added to both.

         -  Repair Depot includes root cause analysis, repair, report generation
            and trending (if desired).
