                   Collectively referred to as "The Parties"


WHEREAS SIEMENS is a designer, manufacturer and distributor of hearing
instruments and components for hearing instruments, including integrated
circuits and hybrids for hearing instruments; and

WHEREAS SYMPHONIX is a designer, manufacturer and distributor of semi-
implantable and totally implantable middle ear hearing devices; and

WHEREAS SIEMENS and SYMPHONIX believe that it will be in both of their best
interests to establish a long-term cooperative relationship in connection with
the global positioning of SIEMENS PRODUCTS and SYMPHONIX PRODUCTS as providing a
single continuum of hearing care for the hearing impaired; and

interests to establish, based on this global positioning, certain joint

SYMPHONIX PRODUCTS in certain markets.


DEFINITIONS
- -----------

"SYMPHONIX PRODUCTS" are defined as all  current and future semi-implantable and
totally implantable middle ear devices designed and / or manufactured by
SYMPHONIX. The current SYMPHONIX PRODUCTS are listed in Annex 1. Future
                                                        -------
SYMPHONIX PRODUCTS will be included as soon as practical after they become
available.

"SIEMENS PRODUCTS" are defined as all current and future hearing instruments
designed and / or manufactured by SIEMENS.

"TERRITORY"  is defined as the countries listed in Annex 2.
                                                   -------


1.  Global Marketing Alliance

SIEMENS and SYMPHONIX shall use their best efforts to jointly promote SIEMENS
PRODUCTS and SYMPHONIX PRODUCTS in the global market.

SYMPHONIX PRODUCTS shall be positioned as superior, technologically advanced
hearing care solutions that address unmet needs of hearing impaired people who
are dissatisfied with hearing instruments and therefor are candidates for semi-
implantable or totally implantable hearing devices.

SIEMENS PRODUCTS shall be positioned as superior, technologically advanced
hearing instruments.

Together, SIEMENS PRODUCTS and SYMPHONIX PRODUCTS will be positioned as
providing a single continuum of care for the hearing impaired. This joint
positioning by SIEMENS and SYMPHONIX will be exclusive, as to hearing
instruments and semi-implantable and totally implantable hearing devices.


2.  Marketing Cooperation

The Parties agree that they will conduct cooperative marketing programs such as
the following:

(i)   joint multimedia programs, including educational programs and workshops
      aimed at increasing awareness of hearing health care and the benefits of
      the SYMPHONIX PRODUCTS among dissatisfied hearing instrument users,
      audiologists and hearing instrument dispensers;

(ii)  joint attendance at workshops and scientific conferences and sponsorship
      of satellite meetings;

(iii) joint attendance at medical / audiological conferences;

(iv)  joint sponsorship of educational forums aimed at hearing impaired
      individuals;

(v)   joint market research studies;

(vi)  joint creation of patient support groups; and

(vii) joint development of a patient data base that produces  cross-referral of
      patients.

The Parties agree that they will develop specific programs designed to actively
involve hearing instrument dispensers in the promotion of the SYMPHONIX
PRODUCTS. Such programs will be designed to provide  incentives  to achieve
referral of potential patients to clinical implanting sites. Such programs may
include sale by the hearing instrument dispenser of the external audio processor
(external part of the semi-implantable hearing device), as well as referral fees
and fitting fees.


The Parties intend that these programs will be initiated in the TERRITORY, i.e.
during Q 4 of calendar 1999 in France, during Q 1 of calendar 2000 in Spain,
Germany and UK, and as soon as practical in the other countries of the
TERRITORY. The Parties intend that such programs will be fully implemented in
the United States of America and Canada immediately after initiation of
commercial sales. In all other countries such programs will be implemented if
reasonably possible to do so. Any claims regarding The Parties' respective
products shall be subject to approval by SYMPHONIX for SYMPHONIX PRODUCTS and by
SIEMENS for SIEMENS PRODUCTS.


3.  Distribution

SIEMENS is hereby appointed to be the exclusive distributor of SYMPHONIX
PRODUCTS in the TERRITORY, subject to the provisions of Section 4.

The Parties will continually monitor the potential distribution of SYMPHONIX
PRODUCTS in countries not currently included in the TERRITORY. However, it is
expressly agreed that the TERRITORY and the provisions of this paragraph, do not
and will not in the future, include the United States of America and Canada. As
existing SYMPHONIX distribution contracts with third party distributors expire,
or SIEMENS foresees marketing potential for SYMPHONIX PRODUCTS or SYMPHONIX
prepares for distribution of SYMPHONIX PRODUCTS in additional countries,
SYMPHONIX and SIEMENS shall negotiate in good faith the addition of such
countries to the TERRITORY.

The distribution rights include but are not limited to the direct sale to local
distributors, hospitals, ENT doctors, dispensers, health insurance companies and
end users.


4.  Existing SYMPHONIX Distribution Agreements with third Parties;
    SIEMENS Distributors

The designation of certain countries in Annex 2 as part of the TERRITORY, is
contingent on appropriate termination by SYMPHONIX of existing distribution
agreements. The Parties will cooperate in these cases, subject to the following
paragraph, to ensure as smooth as possible a transition from the existing
distribution agreement to SIEMENS or to a new distribution agreement with the
appropriate third party SIEMENS distributor. The countries covered by this
paragraph are Italy, Spain, Portugal, Denmark and Sweden.


In all cases, where SIEMENS wants to appoint third party distributors in the
TERRITORY for purposes of this AGREEMENT, such appointment is contingent on
SYMPHONIX's explicit  prior written approval which shall only be withheld if the
third party distributor distributes products which are directly in competition
to SYMPHONIX PRODUCTS, or if the third party distributor can not qualify to
market the SYMPHONIX PRODUCTS.

SIEMENS shall ensure that distribution rights granted to its third party
distributors are consistent with the provisions of this Agreement, and do not
exceed the rights granted hereunder to SIEMENS.


5.  Scope and Limitation of SIEMENS' Distribution Authority

SIEMENS and SYMPHONIX shall use their reasonable efforts to develop a
comprehensive business plan for distribution of SYMPHONIX PRODUCTS in the
TERRITORY  within a period of sixty (60) days after the effective date of this
AGREEMENT. Such business plan will address specific programs and resource
allocations on a country-by-country basis, and will be updated regularly at
least on a yearly basis.

5.1  Introduction Period

     The Parties have agreed on principles for such business plan for the period
     of the first two (2) years after the effective date as provided in section
     14 ("Introduction Period") as follows:

     SIEMENS shall perform in its own name and for its own account all
     warehousing, shipping, returns handling, order processing, and invoicing
     for SYMPHONIX PRODUCTS;

     SYMPHONIX shall provide SIEMENS with adequate quantities of SYMPHONIX
     PRODUCTS on a consignment basis and SIEMENS will issue purchase orders
     weekly for such SYMPHONIX PRODUCTS, when sold to third party customers
     (including third party distributors);

     SYMPHONIX shall pay to SIEMENS an amount equal to 5% of the amount invoiced
     by SIEMENS (excluding taxes, freight and similar items) to third party
     customers and distributors as a handling fee. Such handling fee will be
     offset with the purchase price for the corresponding purchase of SYMPHONIX
     PRODUCTS by SIEMENS;


     SIEMENS shall purchase SYMPHONIX PRODUCTS from SYMPHONIX at prices equal to
     SYMPHONIX's list prices, unless SYMPHONIX has explicitly agreed to a
     different price for specific transactions;

     SIEMENS shall pay all applicable taxes (such as VAT), freight, duty and
     similar items due in the TERRITORY and may invoice these as appropriate to
     third party distributors and customers;

     SIEMENS shall pay all invoices for SYMPHONIX PRODUCTS within thirty (30)
     days of the invoice date (net of the 5% handling fee described above);

     SYMPHONIX shall retain title to SYMPHONIX PRODUCTS until shipped by SIEMENS
     to third party distributors or customers;

     SIEMENS will keep accurate records of the consignment inventory (including
     by serial numbers), and will make such records available to SYMPHONIX upon
     request, including by submission of periodic detailed inventory reports;

     SIEMENS will keep such records, maintain the inventory and process
     transactions in such a way as to be in compliance with the applicable E.U.
     directives for active implantable medical devices and U.S. regulations for
     Class III medical devices;

     SIEMENS and SYMPHONIX will agree on a yearly budget with detailed
     assignment of cost to be borne by each of the Parties;

     SYMPHONIX will be responsible for promotion as well as for clinical and
     technical support with surgeons and hospitals, and will bear the cost for
     its support personnel in the TERRITORY;

     SIEMENS will be responsible for promotion with hearing aid dispensers and
     will bear the cost of its hearing instruments sales and support personnel
     in the TERRITORY;

     SYMPHONIX will render the technical and clinical support to SIEMENS
     subsidiaries, third party distributors or any other party interested in
     SYMPHONIX PRODUCTS.


5.2  Subsequent Period

     Commencing two (2) years from the effective date provided in section 14,
     ("Subsequent Period") SIEMENS will assume the distribution responsibility
     for the SYMPHONIX PRODUCTS under the following principles:

     SYMPHONIX PRODUCTS will be purchased by SIEMENS at prices providing SIEMENS
     with a discount from SYMPHONIX's price list. Such discount will be at least
     50%. The Parties agree that a discount above 50% for SIEMENS is possible.
     However, the purchase price to SIEMENS for SYMPHONIX PRODUCTS should allow
     SYMPHONIX at least a 20% manufacturing margin, fully loaded manufacturing
     cost considered. The Parties agree that a manufacturing margin of greater
     than 20% for SYMPHONIX is possible. The SIEMENS purchase prices for
     SYMPHONIX PRODUCTS shall be reviewed on an annual basis by the Parties;

     SIEMENS shall be fully responsible for developing the market in the
     TERRITORY, for promoting and selling SYMPHONIX PRODUCTS in the TERRITORY
     and for determining its sales prices for SYMPHONIX PRODUCTS. SIEMENS shall
     maintain the organization and commit to resources to ensure optimum sales
     for SYMPHONIX PRODUCTS under the mutually revised business plan;

     From the beginning of the Subsequent Period, i.e. after two (2) years from
     the effective date provided in section 14, SIEMENS will assume the direct
     sales and support organization of SYMPHONIX with such personnel becoming
     employees of SIEMENS, providing that the Parties will have consulted and
     mutually agreed upon any increases in staffing levels during the
     Introduction Period;

     SIEMENS will keep adequate records, maintain the inventory and process
     transactions in such a way as to be in compliance with the applicable E.U.
     directives for active implantable medical devices and U.S. regulations for
     Class III medical devices;

     Payment terms will be the same as during the Introduction Period, but title
     and risk of loss will pass at the time of shipment by SYMPHONIX, such
     shipments being FOB San Jose (INCOTERMS 1990).


5.3  Regulatory Compliance
     During both, the Introduction Period and the Subsequent Period, SIEMENS
     shall assist SYMPHONIX as follows in complying with regulatory requir-
     ments.

     SIEMENS shall refer any complaints regarding SYMPHONIX PRODUCTS to
     SYMPHONIX within two (2) working days after they had become known by
     SIEMENS, and if a complaint requires follow up actions to be taken, SIEMENS
     will provide all required information available at SIEMENS to SYMPHONIX
     within one (1) working day.

     Pursuant to the United States Federal Drug Administration's ("FDA") Medical
     Device Reporting Regulations and E. U. vigilance reporting requirements,
     SYMPHONIX may be required to report to the FDA and European regulatory
     agencies information that reasonably suggests that a SYMPHONIX PRODUCT may
     have caused or contributed to the death or serious injury or has
     malfunctioned and that the device would be likely to cause or contribute to
     a death or serious injury if the malfunction were to recur. SIEMENS agrees
     to supply to SYMPHONIX any such information available at SIEMENS within
     forty-eight (48) hours after becoming aware of such information so that
     each can comply with governmental reporting requirements. In the event that
     a SYMPHONIX PRODUCT is recalled, SIEMENS shall cooperate with and assist
     SYMPHONIX in locating, and retrieving if necessary, recalled SYMPHONIX
     PRODUCTS from SIEMENS' customers.

     SIEMENS shall maintain a system of traceability of the SYMPHONIX PRODUCTS
     including the following consignee information in respect of each SYMPHONIX
     PRODUCT sold: (1) SYMPHONIX part number, (2) date of receipt of SYMPHONIX
     PRODUCT from SYMPHONIX, (3) serial numbers / expiration date, (4) invoice
     number under which the unit was shipped to SIEMENS` customer, (5) date of
     shipment of unit from SIEMENS` warehouse, (6) name and address of SIEMENS'
     consignee (this shall at a minimum be to the level of the hospital or
     clinic).

     SIEMENS shall use its best efforts to encourage customers to complete and
     submit the registration cards included with each SYMPHONIX PRODUCT.

     SIEMENS shall allow SYMPHONIX access to audit inventory processing for
     conformance to the requirements of EN ISO 9001.


6.  Commercial Transactions

Commercial transactions concerning SYMPHONIX PRODUCTS shall be performed by
SIEMENS in its own name and on its own account. However, product liability shall
be borne by SYMPHONIX as per Section 11 of this AGREEMENT.


7.  Future Product Development

The Parties enter into this AGREEMENT to establish a long term relationship.
SYMPHONIX shall therefore include SIEMENS and SIEMENS shall include SYMPHONIX as
a participant in its process for the definition and specification of future
products. SYMPHONIX shall make all future SYMPHONIX PRODUCTS  available to
SIEMENS for the distribution in the TERRITORY, and such SYMPHONIX PRODUCTS shall
be marketed by SIEMENS as soon as practical after they become available.


8.   Products

From time to time Annex 1 shall be modified by adding newly developed SYMPHONIX
PRODUCTS and by deleting obsolete and discontinued SYMPHONIX PRODUCTS. However,
any SYMPHONIX PRODUCT discontinuation will be announced with six (6) months
written notice to SIEMENS. SYMPHONIX will make available to SIEMENS for a period
of at least seven (7) years accessories, spare parts and replacement SYMPHONIX
PRODUCTS of any SYMPHONIX PRODUCT after the effective date of its
discontinuation.


9.  Confidentiality

SIEMENS shall not use for its own benefit (except as authorized in this
AGREEMENT) nor make available nor disclose to third parties any technical or
marketing information (e.g., drawings or specifications) or information of a
confidential nature which it may acquire in the course of its cooperation with
SYMPHONIX, and shall also prevent the aforementioned information from being
disclosed to or used by unauthorized parties. SYMPHONIX shall assume the same
obligation with regard to information received from SIEMENS. The above mentioned
obligation does not apply to information which is or will become part of the
public domain or which has been publicly disclosed by the other Party without
breach of a confidentiality obligation. The terms of this provision shall
survive the termination of this AGREEMENT  for five (5) years.


10.    Default and Extraordinary Termination

In addition to any other termination rights hereunder, each Party shall have the
right to terminate this AGREEMENT and to pursue all remedies available to such
Party, upon the occurrence of any of the following:

(i)  a material breach by the other Party of any of any material term or
     condition or representation or warranty contained in this AGREEMENT which
     such Party fails to cure within thirty (30) days after written notice
     thereof;
(ii) the other Party's insolvency, admission of inability to pay its debts as
     they become due, filing of a petition for bankruptcy relief or assignment
     for the benefit of creditors.


11.    Liability

11.1. Indemnification for Infringement of Intellectual Property

      SYMPHONIX will defend, at its expense, any action brought against SIEMENS
      or SIEMENS' subsidiaries, affiliates, agents, employees or customers to
      the extent that it is based on a claim that a SYMPHONIX PRODUCT, when used
      in accordance with this Agreement, infringes a patent, trademark or
      copyright in the TERRITORY. SYMPHONIX will pay any costs, settlements and
      damages finally awarded provided that SIEMENS or SIEMENS' subsidiaries,
      affiliates, agents, employees or customers

      (i)   promptly notifies SYMPHONIX in writing of any claim,

      (ii)  gives SYMPHONIX sole control of the defense and settlement, and

      (iii) provides all reasonable assistance in connection therewith.
      SYMPHONIX agrees to keep SIEMENS or SIEMENS' subsidiaries, affiliates,
      agents, employees or customers advised of the status of any claim.

      If any SYMPHONIX PRODUCT is finally adjudged to so infringe, or in
      SYMPHONIX's opinion such a claim is likely to succeed, SYMPHONIX will, at
      its option

      (i)   procure for SIEMENS the right to continue using the SYMPHONIX
            PRODUCT,

      (ii)  modify or replace the SYMPHONIX PRODUCT so there are no
            infringements, or

      (iii) refund the price paid including handling charges for logistics upon
            return of the

            SYMPHONIX PRODUCT.


       The foregoing states the entire liability of SYMPHONIX and the exclusive
       remedy for SIEMENS or SIEMENS' subsidiaries, affiliates, agents,
       employees or customers relating to infringement or claims of infringement
       of any patent, trademark, copyright, mask work right, trade secret or
       other proprietary right by the SYMPHONIX PRODUCT.

11.2.  Product Liability Indemnification

       SYMPHONIX agrees to defend against and indemnify and hold SIEMENS or
       SIEMENS' subsidiaries, affiliates, agents, employees or customers
       harmless from product liability claims, losses, damages or expenses
       (including costs of defending any proceedings) resulting from the
       purchase, sale, storage, transportation or foreseeable use of SYMPHONIX
       PRODUCTS, whether brought under theories of express or implied warranty,
       negligence or strict liability. This indemnification will not apply to
       any SYMPHONIX PRODUCT which, as determined by arbitration or a competent
       courts decision, has been

       (i)   modified without SYMPHONIX's written authorization,

       (ii)  not used or maintained in compliance with SYMPHONIX's instructions,

       (iii) subjected to misuse, improper maintenance, unusual stress or
             accident, or

       (iv)  used or sold after the "Use Before" date specified by SYMPHONIX.

11.3.  Conditions to Indemnification Obligations

       The indemnification obligations are subject to the following conditions:

       (i)   the indemnified party gives prompt notice to SYMPHONIX of the
             potential liability or claim;

       (ii)  the indemnified party promptly grants to SYMPHONIX control over its
             defence and settlement; and

       (iii) the indemnified party, at the indemnifying party's expense,
             provides reasonable and timely assistance in defence of the claim.
             The indemnified party may, at its option and expense, participate
             in the defence and settlement of any claim or liability under this
             AGREEMENT; however, if the indemnified party agrees to a settlement
             of such claim or liability without the written consent of
             SYMPHONIX, SYMPHONIX shall have no obligation to indemnify the
             indemnified party in connection with such settlement.

11.4.  Product Liability Insurance

       SYMPHONIX shall, for the lifetime of the SYMPHONIX PRODUCTS, secure and
       maintain a product liability insurance policy providing coverage for
       product liability exposure (including negligence and strict liability) to
       third parties resulting from defective SYMPHONIX PRODUCTS (such as
       design-, manufacture-, instruction defects) supplied


       by SYMPHONIX to SIEMENS in the TERRITORY, provided such coverage is
       available on commercially reasonable terms. At SIEMENS' request,
       SYMPHONIX shall provide SIEMENS a copy of the insurance policy. The
       Parties shall, during the term of this agreement, discuss annually the
       level of insurance coverage maintained by SYMPHONIX.

11.5.  General Indemnity

       Unless otherwise provided for this Agreement, either Party will indemnify
       and hold the other Party harmless from and against any and all losses,
       damages, claims, liabilities, cost and expenses (including reasonable
       attorneys` fees) directly resulting from

       (i)   any gross negligent or intentional breach of this Agreement or any
             duty or obligations hereunder, or

       (ii)  any claims that may be made by reason of any gross negligent or
             intentional act or omission of a Party or any of its subsidiaries,
             affiliates, agents or employees.


12.    WARRANTIES

12.1   SYMPHONIX warrants to SIEMENS that the SYMPHONIX PRODUCTS will on the
       date of shipment be free from defects in materials and workmanship, and
       will under normal use, starting with the date of implantation, conform in
       material respects to the then-current user documentation for a period of
       three (3) years for the implanted portion of such SYMPHONIX PRODUCT and
       for a period of one (1) year for its external portion, but at least for
       the mandatory period under the regulations of the E. U.. This limited
       warranty will not apply to any SYMPHONIX PRODUCT which as proved by
       SYMPHONIX, has been

       (i)   modified without SYMPHONIX's written authorization,

       (ii)  not used or maintained in compliance with SYMPHONIX's instructions,

       (iii) subjected to misuse, improper maintenance, unusual stress or
             accident, or

       (iv)  used or sold after the "Use Before" date specified by SYMPHONIX.

       This limited warranty extends only to SIEMENS and not to any end user or
       customer of SIEMENS. The provisions of this Section 12.1 shall not affect
       the statutory rights of any end-user in the TERRITORY.

12.2.  SIEMENS shall use its best efforts to ensure with its customers that
       procedures for ordering of SYMPHONIX PRODUCT and shipment of stock
       precludes having expired SYMPHONIX PRODUCT in stock. Expired SYMPHONIX
       PRODUCT must not be sold and is not returnable except for re-
       sterilization, at the cost, including freight, of SIEMENS. SYMPHONIX may
       by notice in writing require SIEMENS to return any expired


       SYMPHONIX PRODUCT to SYMPHONIX for re-sterilization which shall be
       performed at the cost including freight of SIEMENS.

12.3   SYMPHONIX shall pass on to SIEMENS good title, free and clear of all
       liens and/or encumbrances to SYMPHONIX PRODUCTS delivered as replacement
       for non-conforming SYMPHONIX PRODUCTS.

12.4   If SYMPHONIX is unable, within sixty (60) business days of SYMPHONIX'
       receipt of defective SYMPHONIX PRODUCTS, to repair or replace non-
       conforming SYMPHONIX PRODUCTS, SIEMENS shall be credited the original
       purchase price for such SYMPHONIX PRODUCTS. In case of a warranty defect,
       which requires a removal from the patients body of defective SYMPHONIX
       PRODUCTS as well as a re-implant of repaired/replaced SYMPHONIX PRODUCTS
       all direct cost for such surgery, to be paid by SIEMENS shall be borne by
       SYMPHONIX, provided SYMPHONIX has approved in advance of the need for
       such removal and re-implant, or that there is a mandatory medical
       indication that is directly related to defective SYMPHONIX PRODUCTS.

12.5   SIEMENS shall make no representations to third parties regarding the
       performance or functional capabilities or characteristics of the
       SYMPHONIX PRODUCTS beyond those stated in SYMPHONIX's then-current
       printed Product Specification.


13.   Assignment

Neither Party may assign or otherwise transfer this AGREEMENT, or assign any of
its rights or delegate any of its obligations hereunder, without the prior
written consent of the other Party, and any attempted or purported assignment by
either Party without such consent shall be null and void. Notwithstanding the
foregoing, either Party may assign all of its rights and delegate all of its
obligations hereunder in connection with the sale of all or substantially all of
its assets or the reorganization of the assignor, without the prior written
consent of the other Party; provided, however, that any such assignee must
assume all obligations of the assignor under this AGREEMENT to the reasonable
satisfaction of the non-assigning Party.


14.   Duration of AGREEMENT, Ordinary Termination

This AGREEMENT shall become effective upon signature by both Parties of both
this Agreement and the Common Stock Purchase Agreement between the Parties, and
shall remain in force for a period of five (5) years. Notwithstanding the
foregoing, this AGREEMENT shall not terminate before September 30, 2004, except
as provided in Section 10 and 15.

Unless either Party has given twelve (12) months written notice of intent to not
renew this AGREEMENT, this AGREEMENT shall automatically renew for successive
one (1) year periods beyond September 30, 2004. After this date, this AGREEMENT
will be cancelable by either Party upon twelve (12) month written notice to the
other Party.

If SYMPHONIX decides not to renew the Agreement a fee will be payable by
SYMPHONIX to SIEMENS, such fee is  one times the SIEMENS' prior twelve months
revenues with SYMPHONIX PRODUCTS in the TERRITORY.

Such fee will be payable 60 days after the effective date of the termination of
this AGREEMENT.


15.   SYMPHONIX Change of Control

In the event of a Change in Control of SYMPHONIX (as defined herein), SYMPHONIX
shall have the right to terminate, with three (3) months written notice, this
AGREEMENT by paying SIEMENS the greater of (i) US$ 1,000,000 or 2 times SIEMENS'
prior twelve months revenues with SYMPHONIX PRODUCTS in the TERRITORY if this
AGREEMENT is terminated during the first or second year of the initial term of
this AGREEMENT, (ii) US$ 1,000,000 or 1.5 times  SIEMENS' prior twelve months
revenues with SYMPHONIX PRODUCTS in the TERRITORY if this AGREEMENT is
terminated during the third year of the initial term or (iii) US$ 2,000,000 or 1
times SIEMENS' prior twelve months revenues with SYMPHONIX PRODUCTS in the
TERRITORY if this AGREEMENT is terminated during the fourth or fifth year of the
initial term. Upon a termination of this AGREEMENT for such reason SYMPHONIX

A "Change in Control of SYMPHONIX" shall mean

(i)   a merger, consolidation or other business combination or transaction to
      which SYMPHONIX is a party if the stockholders of SYMPHONIX immediately
      prior to the effective date of the merger, consolidation or other business
      combination or transaction as a result of such share ownership own less
      than 50 % of the voting power of the surviving corporation following such
      merger, consolidation, or other business combination or transaction,

(ii)  an acquisition by any person of voting stock of SYMPHONIX representing 20
      % or more of the total current voting power of SYMPHONIX,

(iii) a sale of all or substantially all the assets of SYMPHONIX or

(iv)  a liquidation or dissolution of SYMPHONIX.

If the change in control results in an acquisition of SYMPHONIX by a
manufacturer of acoustic hearing aids, then this AGREEMENT may be cancelled by
SIEMENS at SIEMENS' option. Payments will be as set out above.


16.   Arbitration

The Parties shall make a good faith effort to settle amicably any dispute or
difference arising out of or resulting from this AGREEMENT or ancillary
agreements regarding its performance. An attempt to arrive at a settlement shall
be deemed to have failed as soon as one of the Parties to this AGREEMENT so

and exclusively by arbitration under the rules of arbitration of the
International Chamber of Commerce in Paris ("Rules") by three (3) arbitrators

that place shall apply where the Rules are silent. It is agreed that all
documentary submissions, presentations, and proceedings shall be in the English
language.

The arbitral award shall be substantiated in writing. The decision of the
arbitral tribunal shall be final and binding on the Parties, and judgement upon
the arbitral award may be entered in any court having jurisdiction thereof. The
arbitral tribunal shall assign the costs of arbitration.


17. Applicable Law

The contractual relations between the Parties shall be governed by the
provisions of this AGREEMENT and all other agreements regarding its performance,
