                        COMMON STOCK PURCHASE AGREEMENT

     This Agreement is made as of September 18, 2000 by and among Symphonix

                                  Definitions
                                  -----------

     "Affiliate" shall have the meaning set forth in Rule 12b-2 of the rules and
regulations promulgated under the Exchange Act; provided, however, that for
purposes of this Agreement, the Investors and their respective Affiliates, on
the one hand, and the Company and its Affiliates, on the other, shall not be
deemed to be "Affiliates" of one another.

the Exchange Act.

the average of the highest bid and lowest asked prices on such day in the
domestic over-the-counter market as reported by the National Quotation Bureau,
Incorporated, or any similar or successor organization (and in each such case
excluding any trades that are not bona fide, arm's length transactions).  If at

proposed that one be selected, the investment banking firm will be selected by
an arbitrator located in Santa Clara County, California, selected by the
American Arbitration Association (or if such organization ceases to exist, the

shall select the investment banking firm (within ten (10) days of its

interest of the Investors, of not more than four investment banking firms of
national standing in the United States, of which no more than two may be named
by the Company and no more than two may be named by a majority in interest of
the Investors. The arbitrator may consider, within the ten-day period allotted,
arguments from the parties regarding which investment banking firm to choose,
but the selection by the arbitrator shall be made in its sole discretion from
the list of four. The determination of the Fair Market Value by such investment
banking firm shall be final and binding upon the parties, and the Company shall
pay all of the fees and expenses of the investment banking firm and arbitrator
(if any) used to determine the Fair Market Value.

     "Investors' Pro Rata Portion" shall mean (i) in the case of the issuance of

purchased by the Investors, would result in the Investors maintaining their
percentage interest in the Total Current Voting Power of the Company in effect
immediately prior to such issuance of Voting Stock or (ii) in the case of the
issuance of any other securities other than Voting Stock, that number of shares
of such stock to be issued which, if purchased by the Investors, would result in

or in replacement of, Common Shares, Additional Shares or New Securities.

Company that covers any of the Registrable Securities registered pursuant to the

           (b)  Either JP Morgan or Patricof may elect to exercise the
Adjustment on behalf of all Investors, subject to Section 2.2(e), by completing,
executing and delivering to the Company the Notice of One-Time Adjustment (the
"Adjustment Notice"), the form of which is attached hereto as Exhibit B.

Exchange Act of 1934, as amended, and (ii) has sold any Company securities

addition, any Investor (a "Non-Participating Investor"), other than a Restricted
Investor, may elect not to participate in the Adjustment initiated pursuant to
Section 2.2(b) by providing notice to the Company of such intent within 30 days
of receipt of the Company Notice. The Restricted Investors and the Non-
Participating Investors shall then have the right to subsequently participate in
the Adjustment as set forth in Section 2.2(f) provided that either Patricof or
JP Morgan does not participate in the Adjustment elected pursuant to Section
2.2(b).

           (f)  Either Patricof or JP Morgan, whichever has not participated in
the Adjustment elected pursuant to Section 2.2(b), may elect to exercise the
Adjustment on behalf of all the Restricted Investors and the Non-Participating
Investors by completing, executing and delivering to the Company the Adjustment
Notice. Upon receipt of the Adjustment Notice, the Company shall promptly
provide the Company Notice to each other Investor. The Restricted Investors and

its obligations under and contemplated by this Agreement and the Related
Agreements. This Agreement and the Related Agreements have been or will be at
the Closing, as the case may be, duly executed and delivered by an authorized
officer of the Company and as of the date of this Agreement or the Closing Date,
as the case may be, will constitute legal, valid and binding obligations of the
Company, enforceable against the Company in accordance with their terms, except

relating to or affecting the enforcement of creditors' rights generally and by
limitations of equity, public policy and judicial decisions.

     3.4  SEC Documents; Financial Statements; Subsequent Events. The Company
          ------------------------------------------------------
has filed in a timely manner all documents that the Company was required to file
with the SEC under Sections 13, 14(A) and 15(d) of the Exchange Act, through the
date of this Agreement and all rules and regulations thereunder. As of their
respective filing dates, all documents filed by the Company with the SEC (the
"SEC Documents") complied in all material respects with the requirements of the
Exchange Act or the Securities Act, as applicable, and all rules and regulations
thereunder. None of the SEC Documents contained, as of their respective dates,
any untrue statement of material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements made therein,
in light of the circumstances under which they were made, not misleading, and
such SEC Documents, when read as a whole, do not contain as of the date hereof
any untrue statements of a material fact and do not omit to state a material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading. The financial statements of the
Company included in the SEC Documents (the "Financial Statements") comply in all
material respects with applicable accounting requirements and with the published
rules and regulations of the SEC with respect thereto. The Financial Statements
have been prepared in accordance with United States generally accepted
accounting principles consistently applied and fairly present the financial
position of the Company and any subsidiaries at the dates thereof and the
results of the Company's operations, and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal adjustments, none of
which is material) .

     3.5  Governmental Consents. No consent, approval, order or authorization
          ---------------------
of, or registration, qualification, designation, declaration or filing with, any
federal, state, or local governmental authority on the part of the Company is
required in connection with the execution and delivery of this Agreement and the
Related Agreements and the consummation of the transactions contemplated by this
Agreement and the Related Agreements except (A) for the filing of a Form D with
respect to the issuance of the Common Shares with the SEC and (B) for the filing
of a Nasdaq National Market Notification Form (pursuant to Rule 10b-17
promulgated under the Exchange Act) with Nasdaq.

     3.6  Exempt Transactions. Subject in part to the accuracy of the Investors'
          -------------------
representations and warranties in Section 4 of this Agreement, the offer, sale
and issuance of the Common Shares

                                      -7-
<PAGE>

and the Additional Shares in conformity with the terms of this Agreement shall
constitute transactions exempt from the registration requirements of Section 5
of the Securities Act and from the registration or qualification requirements of
the laws of any applicable state or United States jurisdiction.

     3.7  No Material Adverse Change. Since June 30, 2000, there have not been
          --------------------------
any changes in the assets, liabilities, financial condition, business or
operations of the Company from that reflected in the Financial Statements except
(i) changes in the ordinary course of business which have not been, either
individually or in the aggregate, materially adverse, and (ii) the Company's
continued incurrence of operating losses and negative cash flow.

     3.8   Intellectual Property.
           ---------------------

           (a)  As of the date hereof, set forth in Schedule 3.8 hereto is a
list of all domestic and foreign patents, patent applications, registered
trademarks, trademark applications, registered service marks, service mark
applications, registered trade names and copyright registrations, owned by or
registered in the name of the Company, or of which the Company is a licensor or
licensee or in which the Company has any right and is material to the business
of the Company (collectively, the "Company Intellectual Property"). To the best
of its knowledge generally, and specifically after conducting a reasonable
investigation only with respect to patents held by Hearing Instrument
Manufacturers Patent Partnership ("HIMPP") as referenced in their February 9,
1998 facsimile to the Company, the Company owns or possesses sufficient legal
rights to all of the Company Intellectual Property, in each case free and clear
of any liens, charges, restrictions, claims or encumbrances and without any
conflict with, or misappropriation or infringement of, the rights of others,
necessary for its business as now conducted and as proposed to be conducted by
the Company. To the best of its knowledge, the Company has not infringed,
misappropriated or otherwise violated any intellectual property rights of any
third person. As of the date hereof, set forth in Schedule 3.8 is a list of all
agreements related to Company Intellectual Property (excluding software that may
be purchased over-the-counter for less than $25,000 and any other standard end-
user, object code, internal-use software license and support/maintenance
agreements) to which the Company is party. In each case where a patent or patent
application, trademark registration or trademark application, service mark
registration or service mark application, or copyright registration or copyright
application included in the Company Intellectual Property is held by assignment,
the assignment has been duly recorded with the governmental authority from which
the patent or registration issued or before which the application or application
for registration is pending. None of the trademarks, service marks, applications
for trademarks or applications for service marks included in the Company
Intellectual Property has been the subject of an opposition or cancellation
procedure. There are no claims pending, or to the Company's knowledge,
threatened, that the Company Intellectual Property is invalid or unenforceable
or that the Company has violated or, by conducting its business, would violate
any of the patents, trademarks, service marks, trade names, copyrights, trade
secrets or other proprietary rights or processes of any other person or entity,
and to the best knowledge of the Company, there is no basis for such claim
(whether or not pending or threatened). The Company is not actually aware of any
violation by a third party of any of the Company's patents, trademarks,

                                      -8-
<PAGE>

service marks, trade names, copyrights, trade secrets, licenses, proprietary
rights and processes. The Company is not actually aware that any of its
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of such employee's best efforts to promote the interest of the Company
or that would conflict with the Company's business. Neither the execution or
delivery of this Agreement, nor the carrying on of the Company's business by the
employees of the Company, will, to the Company's actual knowledge, conflict with
or result in a breach of the terms, conditions, or provisions of, or constitute
a default under, any contract, covenant or instrument under which any such
employee is now obligated. The Company does not believe it is or will be
necessary to use any inventions of any of its employees (or persons it currently
intends to hire) made prior to their employment by the Company. That certain
U.S. Patent No. 6,024,717 "Apparatus and Method for Sonically Enhanced Drug
Delivery" issued to Ball et al. on February 15, 2000 is not material to the
business of the Company.

           (b)  The Company has not granted any third party any right to
reproduce, distribute, market, or exploit any Company Intellectual Property.
There exist no restrictions on the disclosure, use or transfer of the Company
Intellectual Property. None of the Company Intellectual Property has been
adjudicated invalid or unenforceable in whole or in part, and, to the actual
knowledge of the Company, all such Company Intellectual Property is valid and
enforceable. The consummation of the transactions contemplated by this Agreement
will not alter, impair or extinguish any Company Intellectual Property. As of
the date hereof, except as set forth in Schedule 3.8, the Company has not given
an indemnity in connection with any intellectual property right to any third
party.

           (c)  All designs, drawings, specifications, source code, object code,
documentation, flow charts, and diagrams incorporating or reflecting any of the
Company Intellectual Property constitute original creations of, and were
written, developed and created solely and exclusively by employees of the
Company without the assistance of any third party or entity or were created by
third parties who assigned ownership of their rights to the Company in
consultant confidentiality and invention assignment agreements, copies of which
have been provided or made available to the Investors or their special counsel.

     3.9   Authorized Capital Stock. As of the date hereof, the authorized
           ------------------------
capital stock of the Company consists of 50,000,000 shares of common stock, par
value $0.001 per share, of which at August 31, 2000, 13,432,770 shares were
issued and outstanding, and 5,000,000 shares of preferred stock par value $0.001

reserved a total of 475,000 shares of Company Common Stock for issuance under
its 1997 Employee Stock Purchase Plan, of which, at August 31, 2000, 146,270

Stock for issuance under its 1994 Stock Option Plan, of which, at August 31,
2000, 2,438,757 shares of Company Common Stock are duly reserved for issuance
upon exercise of outstanding options. As of August 31, 2000, 16,118 shares of
Company Common Stock are reserved for issuance upon exercise of other options,
warrants and rights held by

                                      -9-
<PAGE>

other parties. Except as set forth on Schedule 3.9 hereto, there are no other
options, warrants, conversion privileges, convertible securities or other
contractual rights presently outstanding to purchase or otherwise acquire any
authorized but unissued shares of any of the Company's or any of its
subsidiaries' capital stock or other securities. Except as set forth on Schedule
3.9, there are no preemptive or similar rights to purchase or otherwise acquire
shares of capital stock of the Company or any subsidiary, whether pursuant to
law, the certificates of incorporation or Bylaws of the Company or any of its
subsidiaries, or any agreement or instrument. The issued and outstanding shares
of capital stock of the Company have been duly authorized, validly issued and
are fully paid and nonassessable. Except as set forth in the SEC Documents, no
warrants, options or other rights to purchase, agreements or other obligations
to issue, or agreements or other rights to convert any obligation into, any
shares of capital stock of the Company have been granted or entered into by the
Company. All of the above securities of the Company were issued in compliance
with all applicable federal and state securities laws and were not issued in
violation of or subject to any preemptive rights or other rights to subscribe
for or purchase securities. Except as set forth on Schedule 3.9, the Company is
not a party to or bound by any agreement or commitment pursuant to which the
Company is or could be required to register any securities under the Securities
Act. The Common Shares to be purchased at the Closing shall represent
approximately 31% of the Total Current Voting Power based upon a total of
13,432,770 shares of Company Common Stock outstanding as of August 31, 2000 plus
the 6,397,632 shares to be purchased pursuant to Section 2.1 above and plus the
1,026,062 shares of Company Common Stock to be purchased by Siemens
Audiologische Technik GmbH pursuant to a Common Stock Purchase Agreement dated
December 1, 1999.

     3.10  Litigation. There are no actions, suits, proceedings or
           ----------
investigations pending or, to the best of the Company's knowledge, threatened
against the Company or any of its subsidiaries or properties before or by any
court or arbitrator or any governmental body, agency or official in which there
is a reasonable likelihood (in the good faith judgment of the Company) of an
adverse decision that (A) would have a material adverse effect on the Company's
properties or assets or the business of the Company as presently conducted or
proposed to be conducted or (B) would impair the ability of the Company to
perform in any material respect its obligations under this Agreement. The
Company is not in default with respect to any judgment, order or decree of any
court or governmental agency or instrumentality which, individually or in the
aggregate, could reasonably be expected to have a material adverse effect on the
assets, properties or business of the Company.

     3.11  Compliance With Other Instruments. The business and operations of the
           ---------------------------------
Company and its subsidiaries have been and are being conducted in accordance
with all applicable laws, rules and regulations of all governmental authorities,
except for such violations of applicable laws, rules and regulations which would
not, individually or in the aggregate, have a material adverse effect on the
assets, properties, financial condition or business of the Company. Neither the
execution and delivery of, nor the performance or compliance with, this
Agreement or the Related Agreements by the Company and the transactions
contemplated hereby or thereby, will, with or without the giving of notice or
the passage of time, (i) result in any breach of, or constitute a default under,
or result in the imposition of any lien or encumbrance upon any asset or
property of the Company pursuant to,

                                      -10-
<PAGE>

any agreement or other instrument to which the Company or any of its
subsidiaries is a party or by which it or any of its properties, assets or
rights is bound or affected, except for such breach or default or the imposition
of any such lien or encumbrance which, either individually or in the aggregate,
could not reasonably be expected to have a material adverse effect on the
assets, properties, financial condition or business of the Company or (ii)
conflict with or violate the Certificate of Incorporation or Bylaws of the
Company, or any applicable law, rule, regulation, statute, judgment, order or
decree. The Company is not in violation of its Certificate of Incorporation or
Bylaws nor in violation of, or in default under, any lien, indenture, mortgage,
lease, agreement, instrument, commitment or arrangement, except for such
defaults which would not, individually or in the aggregate, reasonably be
expected to have a material adverse effect on the assets, properties, financial
condition or business of the Company, or subject to any restriction which would
prohibit the Company from entering into or performing its obligations under this
Agreement or the Related Agreements.

     3.12  Brokers or Finders. No person, firm or corporation has or will have,
           ------------------

of any kind except (i) those, if any, reflected in the financial statements

thereunder.

          Representations, Warranties and Covenants of the Investors
          ----------------------------------------------------------

     Each Investor, severally and not jointly, hereby represents and warrants to
the Company as follows:

     4.1   Authorization. (i) Such Investor has all requisite legal and
           -------------
corporate or other power and capacity and has taken all requisite corporate or
other action to execute and deliver this Agreement, to purchase the Common
Shares and the Additional Shares to be purchased by it and to carry out and
perform all of its obligations under this Agreement; and (ii) this Agreement
constitutes the legal, valid and binding obligation of such Investor,
enforceable in accordance with its terms, except (A) as limited by applicable
bankruptcy, insolvency, reorganization, or similar laws relating to or affecting
the enforcement of creditors' rights generally and (B) as limited by equitable
principles generally.

     4.2   Investment Experience. Such Investor is an "Accredited Investor" as
           ---------------------
defined in Rule 501(A) under the Securities Act. Such Investor is aware of the
Company's business affairs and financial condition and has had access to and has
acquired sufficient information about the Company to reach an informed and
knowledgeable decision to acquire the Common Shares and Additional Shares. Such
Investor has such business and financial experience as is required to give it
the capacity to protect its own interests in connection with the purchase of the
Common Shares.

     4.3   Investment Intent. Such Investor is purchasing the Common Shares and
           -----------------
the Additional Shares for its own account as principal, for investment purposes
only, and not with a

                                      -14-
<PAGE>

present view to, or for, resale, distribution or fractionalization thereof, in
whole or in part, within the meaning of the Securities Act. Such Investor
understands that its acquisition of the Common Shares and the Additional Shares
has not been registered under the Securities Act or registered or qualified
under any state securities law in reliance on specific exemptions therefrom,
which exemptions may depend upon, among other things, the bona fide nature of
such Investor's investment intent as expressed herein. Such Investor will not,
directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of
(or solicit any offers to buy, purchase or otherwise acquire or take a pledge
of) any of the Common Shares and the Additional Shares, except in compliance
with the terms of this Agreement and the registration requirements of the
Securities Act, and the rules and regulations promulgated thereunder, or an
exemption thereunder.

     4.4   Registration or Exemption Requirements. Such Investor further
           --------------------------------------
acknowledges and understands that the Common Shares and the Additional Shares
may not be resold or otherwise transferred except in a transaction registered
under the Securities Act or unless an exemption from such registration is
available. Such Investor understands that the certificate(s) evidencing the
Common Shares and the Additional Shares will be imprinted with a legend that
prohibits the transfer of such securities unless (i) they are registered or such
registration is not required, and (ii) except as otherwise provided in Section
2.3(c), if the transfer is pursuant to an exemption from registration under the
Securities Act and, if the Company shall so request in writing, an opinion of
counsel reasonably satisfactory to the Company is obtained to the effect that
the transaction is so exempt.

     4.5   No Legal, Tax or Investment Advice. Such Investor understands that
           ----------------------------------
nothing in this Agreement or any other materials presented to such Investor in
connection with the purchase of the Common Shares or the Additional Shares
constitutes legal, tax or investment advice. Such Investor has consulted such
legal, tax and investment advisors as it, in its sole discretion, has deemed
necessary or appropriate in connection with its purchase of the Common Shares
and the Additional Shares.

           ---------------------------------------------------
of each Investor to purchase the Common Shares at the Closing under this
Agreement is subject to the fulfillment on or prior to the Closing Date of the
following conditions, the waiver of which shall not be effective against any
Investor who does not consent thereto:

           (a)  Representations and Warranties True. The representations and
                -----------------------------------
warranties made by the Company in Section 3 hereof shall be true and correct in
all respects on the Closing Date with the same force and effect as if they had
been made on and as of said date (other than representations and warranties made
specifically with reference to a particular date, which shall have been true and
correct in all respects as of such date), except in each case, or in the
aggregate, as does

                                      -15-
<PAGE>

              Covenants of the Company and the Investors' Rights
              --------------------------------------------------

     8.1   The Investors' Rights to Maintain.
           ---------------------------------

           (a)  In General.  In the event the Company proposes an issuance of
                ----------
New Securities, each Investor shall have the right to purchase for the same
consideration paid by any other purchaser such Investor's Pro Rata Portion, in
whole or in part, at an aggregate purchase price equal to the product of the
lowest price per share at which such New Securities were or will be sold in such
issuance (a price per share as determined in accordance with subsection (b)
below), multiplied by such Investor's Pro Rata Portion or any part thereof (the
"Purchase Price").

           (b)  Issuances of New Securities.
                ---------------------------

                (i)    No fewer than ten (10) and no more than thirty (30)
calendar days prior to the issuance and sale of any New Securities, the Company
shall notify each Investor of the Company's intention to make such issuance by
written notice (the "Company's Issuance Notice") setting forth the number and
type of New Securities and the calculation of each Investor's Pro Rata Portion.

                (ii)   Within fourteen (14) calendar days after receipt by each
Investor of the Company's Issuance Notice, each Investor shall notify the
Company by written notice (the "Investor's Issuance Notice") stating whether
such Investor desires to buy such Investor's Pro Rata Portion, or any part
thereof, for the Purchase Price.

                (iii)  The Company shall promptly, in writing, inform each
Investor that purchases all the New Securities available to it (each, a "Fully-
Exercising Investor") of any other Investor's failure to do likewise. During the
ten (10)-calendar-day period commencing after receipt of such information, each
Fully-Exercising Investor shall be entitled to obtain that portion of the New
Securities for which Investors were entitled to subscribe but which were not
subscribed for by the Investors that is equal to the proportion that the number
of shares of Company Common Stock issued and held, or issuable upon conversion
and exercise of all Convertible Securities then held, by such Fully-Exercising
Investor bears to the total number of shares of Company Common Stock issued and
held, or issuable upon conversion and exercise of all Convertible Securities
then held by all Fully-Exercising Investors.

                (iv)   If the Company issues and sells the New Securities, then
each Investor shall be obligated to purchase (if it has elected to exercise its
right to maintain in the Investor's Issuance Notice) such Investor's Pro Rata
Portion (or part thereof) for the Purchase Price. The closing of any purchases
pursuant to this Section 8.1(b) shall take place contemporaneously, subject to
the provisions of paragraph (c) below. If an Investor either

                                      -19-
<PAGE>

(A) does not deliver an Investor's Issuance Notice within the time periods
specified above or (B) elects in an Investor's Issuance Notice not to purchase
the Investor's Pro Rata Portion or any part thereof the Company shall not be
obligated to sell to the Investor the Investor's Pro Rata Portion.

                (v)    The purchase price per share at which each Investor shall
be entitled to purchase such Investor's Pro Rata Portion shall be determined as
follows:

                       (1)  If the event giving rise to the Investor's rights is
a sale or issuance of New Securities for cash or property, including, without
limitation, for securities or assets by way of merger in connection with the
acquisition of another company, the price shall be the price per share specified
in the agreement relating to such issuance, or if no such price is specified,
the Fair Market Value of the New Securities determined as of the date of
issuance and sale of such New Securities.

                       (2)  If the event giving rise to the Investor's rights is
an issuance of New Securities upon conversion of any security convertible into
or exchangeable for Common Stock or upon exercise of any option, warrant or
right to acquire any New Securities, the price shall be the exercise price per
share of such New Securities determined as of the date of such conversion or
exercise plus a pro-rata portion of the premium paid for the underlying option,
warrant or right.

                       (3)  If the event giving rise to the Investor's rights is
an institutional private placement, the price shall be the price per share at
which the New Securities were sold by the Company.

                       (4)  In all other cases, the price shall be the Fair
Market Value of the New Securities determined as of the date of the issuance and
sale of such New Securities.

           (c)  Closing; Other Matters.
                ----------------------

                (i) The purchase and sale of any New Securities pursuant to this
Section 8.1 shall take place at the offices of the Company contemporaneously
with the closing of the sale of the New Securities to purchasers other than
Investors or at such other time and place as the Company and a majority in
interest of the Investors participating in such issuance of New Securities may
agree.

                (ii) The Company and the Investors shall use their best efforts
to comply with all federal and state laws and regulations and Nasdaq and stock
exchange listing requirements applicable to any purchase and sale of shares of
New Securities under this Section 8.1. The issuance of such shares shall be
subject to compliance with applicable laws and regulations and requirements of
Nasdaq and any applicable stock exchange.

                (iii) Upon receipt of the applicable Investor's Issuance Notice
by the Company, the Investor and the Company each shall be obligated, subject to
the other

                                     -20-
<PAGE>

terms and conditions of this Agreement, to consummate the purchase and sale
contemplated by this Section 8.1 and shall use their best efforts to secure any
approvals required in connection therewith.

                (iv) Any securities acquired by an Investor hereunder and all of
the Investors' rights to maintain, shall be subject to all restrictions and
obligations of the Investor set forth elsewhere in this Agreement including, but
not limited to, Section 7.1 of this Agreement.

                (v)  All of the Company's obligations and the Investor's rights
set forth in this Section 8.1 shall terminate on the fifth anniversary of the
Closing Date.

     8.2   Nasdaq Listing. The Company shall file a listing application with
           --------------
Nasdaq for the Common Shares and the Additional Shares and all Company Common
Stock of the Company held by the Investors and use its best efforts to maintain
the listing of its Common Stock on Nasdaq (or a comparable system then in use)
or the New York Stock Exchange or other national exchange for a period of not
less than three years from the date of issuance.

     8.3   Registration Rights. The Investors shall have the following
           -------------------
registration rights:

           (a)  Shelf Registration.
                ------------------

                (i)  The Company shall prepare and file or cause to be prepared
and filed with the SEC, as soon as practicable but in any event by the date that
is ten (10) days after the Closing Date, a Registration Statement for an
offering to be made on a delayed or continuous basis pursuant to Rule 415 of the
Securities Act registering the resale from time to time by the Investors of the
Registrable Securities. The Registration Statement shall be on an appropriate
form permitting registration of such securities for resale by such Investors in
accordance with the methods of distribution elected by the Investors and set
forth in the Registration Statement. The Company shall use commercially
reasonable efforts to cause the Registration Statement to be declared effective
under the Securities Act as promptly as is practicable and to keep the
Registration Statement continuously effective under the Securities Act until the
earlier of (i) the first anniversary of the Closing Date and (ii) such date as
all securities registered on such Registration Statement have been resold (the
earlier to occur is the "Effectiveness Termination Date"); provided, however,
that the Company may suspend sales of Company Common Stock pursuant to such
Registration Statement for a period of not more than forty-five (45) days in the
aggregate in the event it determines in good faith that such Registration
Statement contains or may contain an untrue statement of material fact or omits
or may omit to state a material fact required to be stated therein or necessary
to make the statement therein not misleading; provided further and subject to
the provisions of this Section 8.3(a)(i), the Company shall promptly amend such
Registration Statement in order to correct any untrue statement and/or ensure
that such Registration Statement is not misleading. At the time the Registration
Statement is declared

                                      -21-
<PAGE>

effective, each Investor shall be named as a selling securityholder in the
Registration Statement and the related prospectus in such a manner as to permit
such Investor to deliver such prospectus to purchasers of registered securities
in accordance with applicable law.

                (ii)   If the Registration Statement ceases to be effective for
any reason at any time prior to the Effectiveness Termination Date (other than
because all securities registered thereunder have been resold pursuant thereto),
the Company shall use its commercially reasonable efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof.

                (iii)  The Company shall supplement and amend the Registration
Statement if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Registration Statement, if
required by the Securities Act or, to the extent to which the Company does not
reasonably object, as reasonably requested by an Investor.

                (iv)   Each Investor agrees that if such Investor wishes to sell
securities pursuant to the Registration Statement, it will do so only in
accordance with this Agreement.

           (b)  Company Registration.
                --------------------

                (i)    Notice of the Investor. If at any time or from time to
                       ----------------------
time, the Company shall determine to register any Company capital stock, for its
own account or for the account of others (other than the Investors), other than
a registration relating solely to employee benefit plans or a registration
relating solely to a Commission Rule 145 transaction or a registration on any
registration form which does not include substantially the same information as
would be required to be included in a registration statement covering the sale
of the Common Shares, the Company will:

                       (1)  Promptly give to each Investor written notice
thereof (which shall include a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable blue sky or
other state securities laws); and

                       (2)  include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Common Shares and Additional Shares specified in a
written request or requests, made within ten (10) days after receipt of such
written notice from the Company, by any Investor.

                (ii)   Underwriting. If the registration of which the Company
                       ------------
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise each Investor as a part of the written notice given
pursuant to Section 8.3(b)(i). In such event the right of an Investor to
registration pursuant to Section 8.3(b) shall be

                                      -22-
<PAGE>

conditioned upon such Investor's participation in such underwriting and the
inclusion of such Investor's Registrable Securities in the underwriting to the
extent provided herein. If an Investor proposes to distribute its Common Shares
and Additional Shares through such underwriting, it shall (together with the
Company) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 8.3, if the Company and the
underwriter determine in good faith that marketing factors require a limitation
of the number of shares to be underwritten, the Company and the underwriter may
limit the number of Registrable Securities to be included in the registration
and underwriting to any amount that the Company and the underwriter may
reasonably determine, but in no event shall (A) any Registrable Securities be
reduced unless all other securities (other than securities to be issued by the
Company) are first entirely excluded from the underwriting, or (B) the amount of
securities of the selling Investors included in the offering be reduced below
25% of the total amount of securities included in such offering.

     No Common Shares or Additional Shares excluded from the underwriting by
reason of the marketing limitation shall be included in such registration.  If
such Investor disapproves of the terms of any such underwriting, it may elect to
withdraw therefrom by written notice to the Company and the underwriter.

           (c)  Form S-3. In addition to the rights contained in the foregoing
                --------
provision of this Section 8.3, the Investors shall have the following rights:

                (i)    Special Situations Private Equity Fund, L.P. and its
investment Affiliates shall have the right at any time during the period
commencing on the Effectiveness Termination Date and ending on the second
anniversary of the Closing Date to request registration on Form S-3 under this
Section 8.3(c) (such request shall be in a writing signed by such Investor and
shall state the number of Registrable Securities to be disposed of and the
intended method of disposition of such securities by such Investor); and

                (ii)   the Investors shall have the right at any time after the
Effectiveness Termination Date to request registration on Form S-3 under this
Section 8.3(c) (such requests shall be in a writing signed by the holders of a
majority in interest of the Common Shares and shall state the number of
Registrable Securities to be disposed of and the intended method of disposition
of such securities by the Investors).

Notwithstanding the foregoing provisions of this Section 8.3(c), the Company
shall not be  required to effect a registration pursuant to this Section 8.3(c)
unless Investors propose to dispose of Common Shares and Additional Shares which
the Investors reasonably anticipate will have an aggregate disposition price
(before deduction of underwriting discounts and expenses of sale) of at least
five hundred thousand dollars ($500,000), provided that the Company shall not be
required to effect a registration pursuant to this Section 8.3(c) if at the time
of the request for a registration on Form S-3 the Company in good faith gives
notice within thirty (30) days of such request that it is engaged or

                                      -23-
<PAGE>

has fixed plans to engage within sixty (60) days of the time of the request in a
firmly underwritten registered public offering (but such notice may not be given
more than once in any six (6) month period), and provided further that the
Company shall not be required to effect more than one registration pursuant to
Section 8.3(c)(i), and provided further that the Company shall not be required
to effect more than one registration pursuant to Section 8.3(c)(ii) in any six
(6) month period, and provided further the Company shall have the right to defer
the filing of the Form S-3 registration statement for a period of up to 60 days
after receipt of the Investor's request if the Company shall furnish to the
Investors a certificate signed by an officer of the Company stating that in the
good faith judgment of the Company's Board of Directors it would be seriously
detrimental to the Company and its stockholders for such Form S-3 to be effected
at such time; provided, however, that the Company may exercise this deferral
only once in any 12 month period.

           (d)  Expenses of Registration. All Registration Expenses incurred in
                ------------------------
connection with any registration pursuant to Section 8.3(a), Section 8.3(b) or
Section 8.3(c) shall be borne by the Company. "Registration Expenses" shall mean

Company and reasonable fees and disbursements of counsel for the Investors, blue
sky fees and expenses, and the expense of any special audits incident to or
required by any such registration (but excluding the compensation of regular
employees of the Company which shall be paid in any event by the Company and
Selling Expenses (as defined hereinafter). All Selling Expenses incurred in
connection with any registrations hereunder, shall be borne by the Investors.

applicable to the sale of the Common Shares and Additional Shares.

           (e)  Registration Procedures. In the case of each registration,
                -----------------------
qualification or compliance effected by the Company pursuant to this Section
8.3, the Company will keep the Investors advised in writing as to the initiation
of each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

                (i)    Subject to Section 8.3(a), keep such registration,
qualification or compliance effective for a period of sixty (60) days or until
the Investors have completed the distribution described in the registration
statement relating thereto, whichever first occurs: provided, however, the
Company may suspend sales of Registrable Securities pursuant to a Registration
Statement for a period of not more than fifteen (15) days in the aggregate in
the event it determines in good faith that such Registration Statement contains
or may contain an untrue statement of material fact or omits or may omit to
state a material fact required to be stated therein or necessary to make the
statement therein not misleading; and provided further that if any such
suspension shall occur, the Company shall keep such Registration Statement
effective for an additional period equal to the period sales were suspended;

                (ii)   Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such

                                      -24-

registration statement as may be necessary to comply with the provisions of the

                (iii)  Furnish to the Investors such numbers of copies of a

           --------
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions;

                (v)    In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Investor
participating in such underwriting shall also enter into and perform its
obligations under such an agreement;

                (vi)   Notify immediately each Investor holding Registrable
Securities covered by such registration statement at any time when a prospectus
relating thereto is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing; provided, however, that the Company shall promptly
amend such Registration Statement in order to correct any untrue statement
and/or ensure that such Registration Statement is not misleading;

                (vii)  Cause all such Registrable Securities registered
hereunder to be listed or included on each securities exchange or automated
quotation system on which similar securities issued by the Company are then
listed or included;

                (viii) Provide a transfer agent and registrar for all
Registrable Securities registered hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration; and

                (ix)   Use its best efforts to furnish, at the request of any
Investor requesting registration of Registrable Securities pursuant to this
Section 8.3, on the date that such Registrable Securities are delivered to the
underwriters for sale in connection with a registration pursuant to this Section
8.3, if such securities are being sold through underwriters, or, if such
securities are not being sold through underwriters, on the date that the
registration statement with respect to such securities becomes effective, (i) an
opinion,

                                      -25-
<PAGE>

dated such date, of the counsel representing the Company for the purposes of
such registration, in form and substance as is customarily given to underwriters
in an underwritten public offering (and reasonably acceptable to the counsel for
the Investors), addressed to the underwriters, if any, and to the Investors
requesting registration of Registrable Securities and (ii) a letter dated such
date, from the independent certified public accountants of the Company, in form
and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering (and reasonably
acceptable to the counsel for the Investors), addressed to the underwriters, to
the extent such letter is permitted under generally recognized accounting
practice.

           (f)  Indemnification
                ---------------

                (i)   The Company will indemnify each Investor, its officers,
directors, employees, partners, affiliates, agents, representatives and legal
counsel, and each person controlling (or deemed controlling) such Investor
within the meaning of the Securities Act, (collectively, the "Investors'
Agents") with respect to which registration, qualification or compliance has
been effected pursuant to this Section 8.3, against all claims, losses, damages
and liabilities (or actions in respect thereof), joint or several, arising out
of or based on (i) any untrue statement (or alleged untrue statement) of a
material fact contained in any prospectus, offering circular or other similar
document or any amendments or supplements thereto (including any related
registration statement and amendments or supplements thereto, notification or
the like) incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances under which they were made, or (ii)
any violation by the Company of any federal, state or common law rule or
regulation applicable to the Company in connection with any such registration,
qualification or compliance, and will reimburse each Investor, and each
Investors' Agent, for any legal and any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, as incurred, provided that the Company will not be liable
in any such case to the extent that any such claim, loss, damage, liability or
expense arises out of or is based on any untrue statement or omission based upon
written information furnished to the Company by an instrument duly executed by
such Investor and stated to be specifically for use therein or furnished in
writing by such Investor to the Company in response to a request by the Company
stating specifically that such information will be used by the Company therein.

                (ii)   Each Investor will indemnify the Company, each of its
directors and officers, each legal counsel and independent accountant of the
Company, each person who controls the Company within the meaning of the
Securities Act, any underwriter, and each other Investor, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other similar document, or any omission (or alleged omission) to state
therein a material fact

                                      -26-
<PAGE>

required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances under which they were made, and
will reimburse the Company, such directors, and officers, control persons,
underwriter and each other Investor for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, as incurred, in each case to the
extent, but only to the extent, that such untrue statement (or alleged untrue
statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished in writing to the Company by an
instrument duly executed by such Investor and stated to be specifically for use
therein or furnished by such Investor to the Company in response to a request by
the Company stating specifically that such information will be used by the
Company therein; provided, however, that the indemnity agreement provided in
this Section 8.3(f)(ii) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the written consent of the Investor, which consent shall not be
unreasonably withheld. In no event shall an Investor's indemnification
obligation exceed the net proceeds received from its sale of Registrable
Securities in such offering.

                (iii)  Each party entitled to indemnification under this Section
8.3(e) (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has received written notice of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom, provided that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld). The Indemnified Party may participate in such defense
at such party's expense; provided, however, that the Indemnifying Party shall
bear the expense of such defense of the Indemnified Party if representation of
both parties by the same counsel would be inappropriate due to actual or
potential conflicts of interest. The failure of any Indemnified Party to give
notice within a reasonable period of time as provided herein shall relieve the
Indemnifying Party of its obligations under this Section 8.3(f), but only to the
extent that such failure to give notice shall materially adversely prejudice the
Indemnifying Party in the defense of any such claim or any such litigation. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation.

                (iv)   If the indemnification provided for in this Section
8.3(f) is held to be unavailable to an Indemnified Party with respect to any
loss, liability, claim, damage or expense referred to therein, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder,
shall contribute to the amount paid or payable by such Indemnified Party as a
result of such loss, liability, claim, damage, or expense in such

                                      -27-
<PAGE>

proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage or expense as well as any other relevant equitable considerations;
provided, that in no event shall any contribution by an Investor under this
Section 8.3(f) exceed the net proceeds from the offering received by such
Investor. The relative fault of the Indemnifying Party and of the Indemnified
Party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Indemnifying Party or by
the Indemnified Party and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.

                (v)    Notwithstanding the foregoing, to the extent that the
provisions on indemnification contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

                (vi)   The obligations of the Company and each Investor under
this Section 8.3 shall survive the completion of any offering of the Registrable
Securities in a registration statement under this Section 8.3, and otherwise.

           (g)  Information by the Investor. Each Investor shall furnish to the
                ---------------------------
Company such information regarding such Investor and the distribution proposed
by such Investor as the Company may request in writing and as shall be required
in connection with any registration, qualification or compliance referred to in
this Section 8.

           (h)  Delay of Registration. Each Investor shall not have any right to
                ---------------------
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 8.3.

           (i)  Termination of Registration Rights. All rights and duties
                ----------------------------------
provided for in this Section 8.3 shall terminate on the earlier of (i) the date
five (5) years from the Closing Date, or (ii) with respect to any Investor, the
date that the Investor is able to dispose of all of such Investor's shares in
one three-month period pursuant to Rule 144 and such Investor holds less than 1%
of the Company's outstanding securities.

     8.4   New Securities. The Company agrees not to issue any (i) securities
           --------------
senior to the Common Shares with respect to dividends, liquidation preference,
voting rights, registration rights or redemption rights or (ii) Company Common
Shares (excluding any shares sold pursuant to a registration statement filed
with the SEC) sold at a discount to the Fair Market Value in a transaction in
which the Company receives at least $5 million in proceeds from the sale of such
shares for a period of two years from the Closing without the prior written
consent of a majority in interest of the Investors.

     8.5   Reports Under Securities Exchange Act of 1934. With a view to making
           ---------------------------------------------
available to the Investors the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit Investors to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

           (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times so long as the Company
remains subject to the periodic reporting requirements under Sections 13 or
15(d) of the Exchange Act;

           (b)  use its best efforts to take such action as is necessary to
enable the Investors to utilize Form S-3 for the sale of their Registrable
Securities;

           (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

           (d)  furnish to any Investor, so long as the Investor owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144,
the Securities Act and the Exchange Act, or that it qualifies as a registrant
whose securities may be resold pursuant to Form S-3, (ii) a copy of the most
recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company, and (iii) such other information as may be
reasonably requested in availing any Investor of any rule or regulation of the
SEC which permits the selling of any such securities without registration or
pursuant to such form.

     8.6  Assignment of Rights. The rights to cause the Company to register
          --------------------
Registrable Securities pursuant to Section 8.3 may be assigned by an Investor
only to an Affiliate of such Investor. In the event of such assignment, the
transferee shall furnish the Company written notice of such assignment and agree
in writing to be bound by the obligations of the Investor under this Agreement.

     8.7  Stockholders' Meeting. The Company shall, in accordance with the laws
          ---------------------
of the State of Delaware and the Company's Certificate of Incorporation and
Bylaws, use its best efforts to convene a meeting of holders of Company Common
Stock (the "Company Stockholders' Meeting") as promptly as practicable but in no
event more than forty-five (45) days after the Proxy Statement (as defined in
Section 8.8) is declared effective, to consider and vote upon the approval of
the transactions contemplated hereby, including, without limitation, the sale
and issuance of the Common Shares and Additional Shares to the Investors in
accordance with the terms of this Agreement. Subject to fiduciary obligations
under applicable law, the Board of Directors of the Company shall recommend such
approval, shall not withdraw or modify such recommendation and shall solicit
such approval. Without limiting the generality of the foregoing, if the Board of
Directors of the Company withdraws or modifies its recommendation, the Company
shall nonetheless cause the Company Stockholders' Meeting to be convened and a
vote to be taken, and

                                      -29-
<PAGE>

the Board of Directors shall communicate to the Company's stockholders its basis
for such withdrawal or modification.

           (a)  The Company shall as promptly as practicable after the date
hereof prepare and file with the SEC a proxy statement meeting the requirements

thereunder promulgated by the SEC (the "Proxy Statement") to solicit the
approval of the transactions contemplated hereby by the Company's stockholders.
The Company shall use reasonable efforts to have the Proxy Statement declared
effective under the Exchange Act and the rules and regulations promulgated by
the SEC thereunder as promptly as practicable after such filing, and promptly
mail the Proxy Statement to the stockholders of the Company.

           (b)  The Company shall keep the Investors apprised of the status of
matters relating to the Proxy Statement and the Company Stockholders' Meeting,
including promptly furnishing the Investors and their counsel with copies of
notices or other communications received by the Company from the SEC or Nasdaq.

     8.9   Operation of Business. The Company agrees that, between the date of
           ---------------------
this Agreement and the earlier of the termination of this Agreement and the
Closing Date, except as expressly contemplated by any provision of this
Agreement, the business of the Company shall be conducted only in, and the
Company shall not take any action except in, the ordinary course of business
consistent with past practice.

     8.10  Election of Directors. So long as Patricof, on the one hand, and JP
           ----------------------
Morgan, on the other hand, beneficially own 1,230,315 shares of Company Common
Stock (as adjusted for stock splits, stock dividends, recapitalizations and the
like), the Company shall include in the slate of nominees recommended by the
Company's Board of Directors or management to stockholders for election as
directors at each annual meeting of stockholders of the Company the individuals
designated by Patricof and JP Morgan, respectively. The Company's Board of
Directors and management shall vote all shares for which the Company's
management or Board of Directors hold proxies or is otherwise entitled to vote
in favor of the directors designated by Patricof and JP Morgan. In the event
that the director designated by Patricof or JP Morgan shall cease to serve as a
director for any reason, the vacancy resulting thereby shall be filled by a
designee of such party reasonably acceptable to the Company.

     8.11  Information Rights. The Company covenants and agrees to deliver to
           ------------------
the Investors copies of all regularly prepared financial statements (to the
extent such financial statements are not included in SEC Filings required to be
made by the Company) and to notify the Investors, as soon as reasonably
practicable, of any material adverse change in the financial condition,
business, prospects or corporate affairs of the Company. The Company shall
permit each Investor, at such Investor's expense, to visit and inspect the
Company's properties, to examine its books of account and records

                                      -30-
<PAGE>

and to discuss the Company's affairs, finances and accounts with its officers,
all at such reasonable times as may be requested by the Investor; provided

non-voting observer to attend such meeting; provided, however, the Company may
require as a condition precedent to the rights hereunder that such proposed
observer and each person to have access to any information provided by the
Company with respect to such meeting shall agree to hold in trust and confidence
and to act in a fiduciary manner with respect to any and all information so
received; and , provided further that the Company reserves the right not to
provide any information and to exclude such proposed observer from any meeting
or portion thereof if receipt of such information or attendance at such meeting

attorney-client privilege between the Company and its counsel or if such
proposed observer is either a competitor of the Company or is otherwise
unacceptable to the Company in its reasonable judgment.

     8.13  Acquisitions. The Company agrees that it shall not acquire (by

million.

           -----------

further, that the right to terminate this Agreement under this clause (b)
-------
shall not be available (i) to any party whose failure to fulfill any obligation
under this Agreement has been the cause of, or resulted in, the failure of the
Closing to occur on or before such date or (ii) in the event that the Closing
shall not have occurred as a result of a failure of any representation to be
true and correct and the party seeking termination knew of such breach prior to
the date of this Agreement;

           (c)  by either the Company or a majority in interest of the Investors
by giving written notice to the other party or parties if any governmental
authority shall have issued an injunction or other ruling prohibiting the

injunction or other ruling shall not be subject to appeal or shall have become
final and unappealable; or

           (d)  by either the Company or a majority in interest of the Investors
in the event the Company's stockholders do not approve the transactions
contemplated hereby at the Company Stockholder's Meeting.

     9.2   Effect of Termination. In the event of any termination of this
           ---------------------
Agreement pursuant to Section 9.1, all rights and obligations of the parties
hereunder shall terminate without any liability on the part of either party or
its respective subsidiaries and Affiliates in respect thereof, except that such

sale by the Company of Company Common Stock or Convertible Securities to any
financial or strategic investor) or any of the Company's assets or business (a

                         OPINION OF COMPANY COUNSEL

                            ______________, 2000

To the Investors party to the
Symphonix Devices, Inc.
Common Stock Purchase Agreement
dated as of September 18, 2000

     Ladies and Gentlemen:

     Reference is made to the Common Stock Purchase Agreement, dated as of
September 18, 2000 (the "Agreement"), complete with all listed exhibits thereto,
by and among Symphonix Devices, Inc., a Delaware corporation (the "Company"),
and the investors party to the Agreement (the "Investors"), which provides for
the issuance by the Company to the Investors of shares of Common Stock of the
Company.  This opinion is rendered to you pursuant to Section 5.1(d) of the
Agreement, and all terms used herein have the meanings defined for them in the
Agreement unless otherwise defined herein.

     We have acted as counsel for the Company in connection with the negotiation
of the Agreement and the issuance of the Common Shares and Additional Shares.
As such counsel, we have made such legal and factual examinations and inquiries
as we have deemed advisable or necessary for the purpose of rendering this
opinion.  In addition, we have examined, among other things, originals or copies
of such corporate records of the Company, certificates of public officials and
such other documents and questions of law that we consider necessary or
advisable for the purpose of rendering this opinion.  In such examination we
have assumed the genuineness of all signatures on original documents, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all copies submitted to us as copies thereof, the legal
capacity of natural persons, and the due execution and delivery of all documents
(except as to due execution and delivery by the Company) where due execution and
delivery are a prerequisite to the effectiveness thereof.

     As used in this opinion, the expression "to our knowledge" with reference
to matters of fact means that, after an examination of documents made available
to us by the Company, and after inquiries of officers of the Company, but
without any further independent factual investigation, we find no reason to
believe that the opinions expressed herein are factually incorrect.  Further,
the expression "to our knowledge" with reference to matters of fact refers to
the current actual knowledge of the attorneys of this firm who have worked on
matters for the Company solely in connection with the Agreement and the
transactions contemplated thereby.  Except to the extent expressly set forth
herein or as we otherwise believe to be necessary to our
<PAGE>

Symphonix Devices, Inc. Stock Purchase Agreement

Page 2

opinion, we have not undertaken any independent investigation to determine the
existence or absence of any fact, and no inference as to our knowledge of the
existence or absence of any fact should be drawn from our representation of
the Company or the rendering of the opinion set forth below.

     For purposes of this opinion, we are assuming that you have all requisite
power and authority, and have taken any and all necessary corporate or
partnership action, to execute and deliver the Agreement, and we are assuming
that the representations and warranties made by the Investors in the Agreement
and pursuant thereto are true and correct.  We are also assuming that the
Investors have acquired the Common Shares and Additional Shares, for value, in
good faith and without notice of any adverse claims within the meaning of the
California Uniform Commercial Code.

     The opinions hereinafter expressed are subject to the following
qualifications:

           (a)  We express no opinion as to the effect of applicable

upon compilations of the securities laws of such states contained in reporting
services currently available to us.

     Based upon and subject to the foregoing, and except as set forth in the
Agreement, we advise you that in our opinion:

     1.  The Company is a corporation duly organized and validly existing under,
and by virtue of, the laws of the State of Delaware and is in good standing
under such laws.  The Company has requisite corporate power to own and operate
its properties and assets, and to conduct its business.  The Company is
qualified to do business as a foreign corporation in each jurisdiction in which
the failure to be so qualified would have a material adverse effect on the
Company's business, financial condition or results of operations.

     2.  The Company has all requisite legal and corporate power to execute and
deliver the Agreement, to sell and issue the Common Shares and Additional Shares
under the Agreement, and to carry out and perform its obligations under the
terms of the Agreement.

     3.  As of the date hereof, the authorized capital stock of the Company
consists of 50,000,000 shares of Common Stock and 5,000,000 shares of Preferred
Stock.  The Common Shares and Additional Shares issued under the Agreement, when
issued, will be validly issued, fully paid and nonassessable and free of any
liens, encumbrances and preemptive or similar rights contained in the Restated
Certificate of Incorporation or Bylaws of the Company, each as currently in
effect.  To our knowledge, except for rights described in the Agreement, the SEC
Documents, the Restated Certificate of Incorporation or the Bylaws, there are no
other options, warrants, conversion privileges or other rights currently
outstanding to purchase or otherwise acquire any authorized but unissued shares
of capital stock or other securities of the Company, or any other agreements to
issue any such securities or rights, pursuant to any written agreement
identified to us as material by which the Company is bound.

     4.  All corporate action on the part of the Company, its directors and
stockholders necessary for the authorization, execution and delivery of the
Agreement by the Company, the authorization, sale, issuance and delivery of the
Common Shares and the Additional Shares, and the performance of the Company's
obligations under the Agreement has been taken.  The Agreement has been duly and
validly executed and delivered by the Company and constitutes a valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms.

     5.  The execution, delivery and performance of and compliance with the
terms of the Agreement and the issuance of the Common Shares and the Additional
Shares (assuming the issuance of the Additional Shares as of the date hereof,
and also assuming that no Investor has either purchased or sold any of the
Company's securities, including derivative securities, at any
<PAGE>

time during the six months prior to the date hereof) does not violate any
provision of the Restated Certificate of Incorporation or Bylaws, or, to our
knowledge, any provision of any applicable federal or state law, rule or
regulation. To our knowledge, the execution, delivery and performance of and
compliance with the Agreement and the issuance of the Common Shares and the
Additional Shares (assuming the issuance of the Additional Shares as of the
date hereof) have not resulted and will not result in any material violation
of, or constitute a material default under, any indenture, mortgage or deed of
trust or other agreement, instrument, court order, judgment or decree binding
upon the Company and identified to us as material.

     6.  No consent, approval or authorization of or designation, declaration or
filing with any United States or California governmental authority on the part
of the Company is required in connection with the valid execution and delivery
of the Agreement, or the offer, sale or issuance of the Common Shares and the
Additional Shares (assuming the issuance of the Additional Shares as of the date
hereof), or the consummation of any other transaction contemplated thereby,
except the filing with the Nasdaq Stock Market of a notice of listing of
additional shares on Form 10b-17.

     7.  To our knowledge, there are no actions, suits, proceedings or
investigations pending against the Company, any of its officers, directors,
employees or its properties before any court or governmental agency which,
either in any case or in the aggregate, are likely to result in any material
adverse change in the business or financial condition of the Company or any of
its properties, or in any material impairment of the right or ability of the
Company to carry on its business or which questions the validity of the
Agreement or any action taken or to be taken by the Company in connection
therewith.

     8.  Based in part upon the representations to you in the Agreement, the
offer and sale of the Common Shares and the Additional Shares (assuming the
issuance of the Additional Shares as of the date hereof) to you pursuant to the
terms of the Agreement are exempt from the registration requirements of Section
5 of the Securities Act of 1933, as amended, and from the qualification
requirements of the California Corporate Securities Law of 1968, as amended.

     This opinion is furnished to the Investors solely for their benefit in
connection with the purchase of the Common Shares and the Additional Shares, and
may not be relied upon by any other person or for any other purpose without our
prior written consent.

                                 Sincerely,

                               [Closing Date]

To the Investors party to the Common
Stock Purchase Agreement dated
September 18, 2000 between
Symphonix Devices, Inc. and said Investors:

Ladies and Gentlemen:

     Re:  Symphonix Devices, Inc.
     Our File: 16828-000000

     We at Townsend and Townsend and Crew LLP are acting and have acted as
patent counsel to Symphonix Devices, Inc., a Delaware corporation (the
"Company"). We have reviewed Symphonix's intellectual property portfolio and are
rendering the opinions set forth in this opinion letter pursuant to Section
5.1(e) of the Common Stock Purchase Agreement dated September 18, 2000 by and
between the Company and you (the "Agreement") in connection with the sale and
issuance shares of the Company's Common Stock.

     We are familiar with the technology used by the Company in its business and
the manner of its use thereof and, with regard to the Company's patents, are of
the opinion that:

     (i)  nothing has come to our attention that causes us to believe the
     patents listed in Schedule 3.8 to the Agreement are invalid;

     (ii)  to the best of our knowledge, there are no legal or governmental
     proceedings pending relating to patent rights or other proprietary
     information or materials, and to the best of our knowledge, no such
     proceedings are threatened or contemplated by governmental authorities or
     others;

     (iii)  to the best of our knowledge, the Company is not infringing or
     otherwise violating any patent, trade secrets, or other proprietary
     information or materials of others, including the patents held by the
     Hearing Instrument Manufacturers Patent Partnership (HIMPP) as referenced
     in their February 9, 1998 facsimile to Symphonix, and to the best of our
     knowledge, there are no infringements by others of any of the Company's
     patents, trade secrets, or other proprietary information or material which
     in our judgement could affect materially the use thereof by the Company;
     and

     (iv)  we are unaware of licenses or other rights to patents, trade secrets
     or other proprietary information or materials not possessed by the Company
     which are necessary
<PAGE>

     to conduct the business now being or proposed to be conducted by the
     Company as described in the Agreement.

     Our opinion is subject to the following qualifications:

     A.  We are admitted to the bar of the State of California and are admitted
to practice before the district Courts of the United States and the United
States Patent and Trademark Office, and we express no opinion as to the laws of
any other jurisdiction.

     B.  For the purposes of our opinion, we are relying in part on factual
matters certified to us by an officer of the Company as set forth in the
attached Officer's Certificate.

     C.  We represent the Company primarily in patent matters and would not
necessarily expect to be informed of other matters relating to other aspects of
the Company's intellectual property, including trademarks, trade secrets and
licensing matters.

                                     Very truly yours,

                                     James M. Heslin

Crew LLP as follows:

claim of infringement of any patent or patents;

     3.  To the best of my knowledge, the facts set forth in Section 3.8 of the
Agreement are true and correct; and

     4.  To the best of my knowledge, the Company does not need to obtain a

Partnership (HIMPP) and the Company obtains the digital processors used in the
Company's products from a supplier who is a member of HIMPP.

To the Investors party to the Common
Stock Purchase Agreement dated
September 18, 2000 between
Symphonix Devices, Inc. and said Investors:

Ladies and Gentlemen:

     Re:  Symphonix Devices, Inc.
     Our File: BALL-2046

     We at Medlen & Carroll LLP are acting and have acted as patent counsel to
Symphonix Devices, Inc., a Delaware corporation (the "Company").  We have
reviewed the portion of the Company's intellectual property portfolio with which
we are assisting, as indicated on Schedule 3.8 to the Common Stock Purchase
Agreement dated September 18, 2000 by and between the Company and you (the
"Agreement"), and are rendering the opinions set forth in this opinion letter
pursuant to Section 5.1(e) of the Agreement in connection with the sale and
issuance shares of the Company's Common Stock.

     We are familiar with some of the technology used by the Company in its
business and the manner of its use thereof and, with regard to the Company's
Intellectual property that we have assisted with, are of the opinion that:

     (i)  nothing has come to our attention that causes us to believe the
     patents with which we were assisting, as listed in Schedule 3.8 to the
     Agreement, are invalid;

     (ii)  to the best of our knowledge, there are no legal or governmental
     proceedings pending relating to patent rights or other proprietary
     information or materials, and to the best of our knowledge, no such
     proceedings are threatened or contemplated by governmental authorities or
     others;

     (iii)  to the best of our knowledge, the Company is not infringing or
     otherwise violating any patent, trade secrets, or other proprietary
     information or materials, of others, and to the best of our knowledge,
     there are no infringements by others of the Company's patents, with which
     we were assisting, as listed in Schedule 3.8 to the Agreement which, in our
     judgement could affect materially the use thereof by the Company; and

     (iv)  we are unaware of licenses or other rights to patents, trade secrets
     or other proprietary information or materials not possessed by the Company
     which are necessary

           FORM OF OFFICER AND DIRECTOR INDEMNIFICATION AGREEMENT

                           SYMPHONIX DEVICES, INC.

                          INDEMNIFICATION AGREEMENT

     This Indemnification Agreement ("Agreement") is effective as of
_______________ by and between Symphonix Devices, Inc., a Delaware corporation
(the "Company"), and ____________ ("Indemnitee").

     WHEREAS, the Company wishes to provide for the indemnification of, and the
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

     WHEREAS, the Company and Indemnitee recognize the difficulty in obtaining
liability insurance for the Company's directors, officers, employees, agents and
fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance;

     WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same time
as the availability and coverage of liability insurance has been severely
limited;

     WHEREAS, the Company and Indemnitee desire to have in place the additional
protection provided by an indemnification agreement, and to provide
indemnification and advancement of expenses to the Indemnitee to the maximum
extent permitted by Delaware law; and

     WHEREAS, in view of the considerations set forth above, the Company desires
that Indemnitee shall be indemnified and advanced expenses by the Company as set
forth herein;

     NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth below.

     1.  Certain Definitions.
         -------------------

         (a)  "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of
1934, as amended), other than a trustee or other fiduciary holding securities
under an employee benefit plan of the Company acting in such capacity or a
corporation owned directly or indirectly by the stockholders of the Company in
substantially the same proportions as their ownership of stock of the Company,
becomes the "beneficial owner" (as defined in Rule 13d-3 under said Act),
directly or indirectly, of securities of the Company representing more than
50% of the total voting power represented by the Company's then outstanding
Voting Securities, (ii) during any period of two consecutive years,
individuals who at the beginning of such period constitute the Board of
Directors of the Company and any new director whose election by the Board of
Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two thirds (2/3) of the directors then still in
office who either were directors at the
<PAGE>

beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof,
(iii) the stockholders of the Company approve a merger or consolidation of the
Company with any other corporation other than a merger or consolidation which
would result in the Voting Securities of the Company outstanding immediately
prior thereto continuing to represent (either by remaining outstanding or by
being converted into Voting Securities of the surviving entity) at least 80%
of the total voting power represented by the Voting Securities of the Company
or such surviving entity outstanding immediately after such merger or
consolidation, or (iv) the stockholders of the Company approve a plan of
complete liquidation of the Company or an agreement for the sale or
disposition by the Company of (in one transaction or a series of related
transactions) all or substantially all of the Company's assets.

         (b)  "Claim" shall mean with respect to a Covered Event: any
threatened, pending or completed action, suit, proceeding or alternative
dispute resolution mechanism, or any hearing, inquiry or investigation that
Indemnitee in good faith believes might lead to the institution of any such
action, suit, proceeding or alternative dispute resolution mechanism, whether
civil, criminal, administrative, investigative or other.

         (c)  References to the "Company" shall include, in addition to
Symphonix Devices, Inc., any constituent corporation (including any

Symphonix Devices, Inc. (or any of its wholly owned subsidiaries) is a party
which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees, agents or
fiduciaries, so that if Indemnitee is or was a director, officer, employee,
agent or fiduciary of such constituent corporation, or is or was serving at
the request of such constituent corporation as a director, officer, employee,
agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise, Indemnitee shall stand in
the same position under the provisions of this Agreement with respect to the
resulting or surviving corporation as Indemnitee would have with respect to
such constituent corporation if its separate existence had continued.

         (d)  "Covered Event" shall mean any event or occurrence related to
the fact that Indemnitee is or was a director, officer, employee, agent or
fiduciary of the Company, or any subsidiary of the Company, or is or was
serving at the request of the Company as a director, officer, employee, agent
or fiduciary of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action or inaction on the part of
Indemnitee while serving in such capacity.

         (e)  "Expenses" shall mean any and all expenses (including attorneys'
fees and all other costs, expenses and obligations incurred in connection with
investigating, defending, being a witness in or participating in (including on
appeal), or preparing to defend, to be a witness in or to participate in, any
action, suit, proceeding, alternative dispute resolution mechanism, hearing,
inquiry or investigation), judgments, fines, penalties and amounts paid in
settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) of any Claim and any federal,
state, local or foreign taxes imposed on the Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement.

         (f)  "Expense Advance" shall mean a payment to Indemnitee pursuant to
Section 3 of Expenses in advance of the settlement of or final judgement in
any action, suit, proceeding or alternative dispute resolution mechanism,
hearing, inquiry or investigation which constitutes a Claim.

         (g)  "Independent Legal Counsel" shall mean an attorney or firm of

who shall not have otherwise performed services for the Company or Indemnitee
within the last three years (other than with respect to matters concerning the
rights of Indemnitee under this Agreement, or of other Indemnitees under
similar indemnity agreements).

         (h)  References to "other enterprises" shall include employee benefit

Indemnitee with respect to an employee benefit plan; and references to

Indemnitee reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have
acted in a manner "not opposed to the best interests of the Company" as
referred to in this Agreement.

         (i)  "Reviewing Party" shall mean, subject to the provisions of
Section 2(d), any person or body appointed by the Board of Directors in
accordance with applicable law to review the Company's obligations hereunder
and under applicable law, which may include a member or members of the
Company's Board of Directors, Independent Legal Counsel or any other person or
body not a party to the particular Claim for which Indemnitee is seeking

         (j)  "Section" refers to a section of this Agreement unless otherwise
indicated.

         (k)  "Voting Securities" shall mean any securities of the Company

     2.  Indemnification.
         ---------------

         (a)  Indemnification of Expenses.  Subject to the provisions of
              ---------------------------
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to the
fullest extent permitted by law if Indemnitee was or is or becomes a party to
or witness or other participant in, or is threatened to be made a party to or
witness or other participant in, any Claim (whether by reason of or arising in
part out of a Covered Event), including all interest, assessments and other
charges paid or payable in connection with or in respect of such Expenses.

         (b)  Review of Indemnification Obligations.  Notwithstanding the
              -------------------------------------
foregoing, in the event any Reviewing Party shall have determined (in a
written opinion, in any case in which Independent Legal Counsel is the
Reviewing Party) that Indemnitee is not entitled to be indemnified hereunder
under applicable law, (i) the Company shall have no further obligation under
Section 2(a) to make any payments to Indemnitee not made prior to such
determination by such Reviewing Party,

                                     -3-
<PAGE>

and (ii) the Company shall be entitled to be reimbursed by Indemnitee (who
hereby agrees to reimburse the Company) for all Expenses theretofore paid to
Indemnitee to which Indemnitee is not entitled hereunder under applicable law;
provided, however, that if Indemnitee has commenced or thereafter commences
--------  -------
legal proceedings in a court of competent jurisdiction to secure a
determination that Indemnitee is entitled to be indemnified hereunder under
applicable law, any determination made by any Reviewing Party that Indemnitee
is not entitled to be indemnified hereunder under applicable law shall not be
binding and Indemnitee shall not be required to reimburse the Company for any
Expenses theretofore paid in indemnifying Indemnitee until a final judicial
determination is made with respect thereto (as to which all rights of appeal
therefrom have been exhausted or lapsed). Indemnitee's obligation to reimburse
the Company for any Expenses shall be unsecured and no interest shall be
charged thereon.

         (c)  Indemnitee Rights on Unfavorable Determination; Binding Effect.
              --------------------------------------------------------------
If any Reviewing Party determines that Indemnitee substantively is not
entitled to be indemnified hereunder in whole or in part under applicable law,
Indemnitee shall have the right to commence litigation seeking an initial
determination by the court or challenging any such determination by such
Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and, subject to the provisions of Section 15, the Company hereby
consents to service of process and to appear in any such proceeding. Absent
such litigation, any determination by any Reviewing Party shall be conclusive
and binding on the Company and Indemnitee.

         (d)  Selection of Reviewing Party; Change in Control.  If there has
              -----------------------------------------------
not been a Change in Control, any Reviewing Party shall be selected by the
Board of Directors, and if there has been such a Change in Control (other than
a Change in Control which has been approved by a majority of the Company's
Board of Directors who were directors immediately prior to such Change in
Control), any Reviewing Party with respect to all matters thereafter arising
concerning the rights of Indemnitee to indemnification of Expenses under this
Agreement or any other agreement or under the Company's Certificate of
Incorporation or Bylaws as now or hereafter in effect, or under any other
applicable law, if desired by Indemnitee, shall be Independent Legal Counsel
selected by Indemnitee and approved by the Company (which approval shall not
be unreasonably withheld). Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be entitled to be indemnified hereunder under applicable law
and the Company agrees to abide by such opinion. The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to
indemnify fully such counsel against any and all expenses (including
attorneys' fees), claims, liabilities and damages arising out of or relating
to this Agreement or its engagement pursuant hereto. Notwithstanding any other
provision of this Agreement, the Company shall not be required to pay Expenses
of more than one Independent Legal Counsel in connection with all matters
concerning a single Indemnitee, and such Independent Legal Counsel shall be
the Independent Legal Counsel for any or all other Indemnitees unless (i) the
employment of separate counsel by one or more Indemnitees has been previously
authorized by the Company in writing, or (ii) an Indemnitee shall have
provided to the Company a written statement that such Indemnitee has
reasonably concluded that there may be a conflict of interest between such
Indemnitee and the other Indemnitees with respect to the matters arising under
this Agreement.

                                     -4-
<PAGE>

         (e)  Mandatory Payment of Expenses.  Notwithstanding any other
              -----------------------------
provision of this Agreement other than Section 10 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim, Indemnitee shall be indemnified against all Expenses incurred by
Indemnitee in connection therewith.

     3.  Expense Advances.
         ----------------

         (a)  Obligation to Make Expense Advances.  Upon receipt of a written
              -----------------------------------
undertaking by or on behalf of the Indemnitee to repay such amounts if it
shall ultimately be determined that the Indemnitee is not entitled to be
indemnified therefore by the Company hereunder under applicable law, the
Company shall make Expense Advances to Indemnitee.

         (b)  Form of Undertaking.  Any obligation to repay any Expense Advances
              -------------------
hereunder pursuant to a written undertaking by the Indemnitee shall be
unsecured and no interest shall be charged thereon.

         (c)  Determination of Reasonable Expense Advances.  The parties agree
              --------------------------------------------
that for the purposes of any Expense Advance for which Indemnitee has made
written demand to the Company in accordance with this Agreement, all Expenses
included in such Expense Advance that are certified by affidavit of
Indemnitee's counsel as being reasonable shall be presumed conclusively to be
reasonable.

     4.  Procedures for Indemnification and Expense Advances.
         ---------------------------------------------------

         (a)  Timing of Payments.  All payments of Expenses (including without
              ------------------
limitation Expense Advances) by the Company to the Indemnitee pursuant to this
Agreement shall be made to the fullest extent permitted by law as soon as
practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than thirty (30) business days after such
written demand by Indemnitee is presented to the Company, except in the case
of Expense Advances, which shall be made no later than ten (10) business days
after such written demand by Indemnitee is presented to the Company.

         (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
              --------------------------------
condition precedent to Indemnitee's right to be indemnified or Indemnitee's
right to receive Expense Advances under this Agreement, give the Company
notice in writing as soon as practicable of any Claim made against Indemnitee
for which indemnification will or could be sought under this Agreement. Notice
to the Company shall be directed to the Chief Executive Officer of the Company
at the address shown on the signature page of this Agreement (or such other
address as the Company shall designate in writing to Indemnitee). In addition,
Indemnitee shall give the Company such information and cooperation as it may
reasonably require and as shall be within Indemnitee's power.

         (c)  No Presumptions; Burden of Proof.  For purposes of this
              --------------------------------
Agreement, the termination of any Claim by judgment, order, settlement
(whether with or without court approval) or conviction, or upon a plea of nolo
                                                                          ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
----------
did not meet any particular standard of conduct or have any particular belief
or that a

                                     -5-
<PAGE>

court has determined that indemnification is not permitted by this Agreement
or applicable law. In addition, neither the failure of any Reviewing Party to
have made a determination as to whether Indemnitee has met any particular
standard of conduct or had any particular belief, nor an actual determination
by any Reviewing Party that Indemnitee has not met such standard of conduct or
did not have such belief, prior to the commencement of legal proceedings by
Indemnitee to secure a judicial determination that Indemnitee should be
indemnified under this Agreement under applicable law, shall be a defense to
Indemnitee's claim or create a presumption that Indemnitee has not met any
particular standard of conduct or did not have any particular belief. In
connection with any determination by any Reviewing Party or otherwise as to
whether the Indemnitee is entitled to be indemnified hereunder under
applicable law, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

         (d)  Notice to Insurers.  If, at the time of the receipt by the
              ------------------
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company
has liability insurance in effect which may cover such Claim, the Company
shall give prompt notice of the commencement of such Claim to the insurers in
accordance with the procedures set forth in the respective policies. The
Company shall thereafter take all necessary or desirable action to cause such
insurers to pay, on behalf of the Indemnitee, all amounts payable as a result
of such Claim in accordance with the terms of such policies.

         (e)  Selection of Counsel.  In the event the Company shall be obligated
              --------------------
hereunder to provide indemnification for or make any Expense Advances with
respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by
Indemnitee (which approval shall not be unreasonably withheld) upon the
delivery to Indemnitee of written notice of the Company's election to do so.
After delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees or expenses of separate counsel
subsequently retained by or on behalf of Indemnitee with respect to the same
Claim; provided that, (i) Indemnitee shall have the right to employ
Indemnitee's separate counsel in any such Claim at Indemnitee's expense and
(ii) if (A) the employment of separate counsel by Indemnitee has been
previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and
expenses of Indemnitee's separate counsel shall be Expenses for which
Indemnitee may receive indemnification or Expense Advances hereunder.

     5.  Additional Indemnification Rights; Nonexclusivity.
         -------------------------------------------------

         (a)  Scope.  The Company hereby agrees to indemnify the Indemnitee to
              -----
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable
law, statute or rule which expands the right of a Delaware corporation to
indemnify a member of its board of directors or an officer, employee, agent or
fiduciary, it is the intent of the parties hereto that Indemnitee shall enjoy
by this Agreement the greater benefits afforded by such change. In the event
of any change in any applicable law, statute or rule which narrows the right
of a

                                     -6-
<PAGE>

Delaware corporation to indemnify a member of its board of directors or an
officer, employee, agent or fiduciary, such change, to the extent not
otherwise required by such law, statute or rule to be applied to this
Agreement, shall have no effect on this Agreement or the parties' rights and
obligations hereunder except as set forth in Section 10(a) hereof.

         (b)  Nonexclusivity.  The indemnification and the payment of Expense
              --------------
Advances provided by this Agreement shall be in addition to any rights to
which Indemnitee may be entitled under the Company's Certificate of
Incorporation, its Bylaws, any other agreement, any vote of stockholders or
disinterested directors, the General Corporation Law of the State of Delaware,
or otherwise. The indemnification and the payment of Expense Advances provided
under this Agreement shall continue as to Indemnitee for any action taken or
not taken while serving in an indemnified capacity even though subsequent
thereto Indemnitee may have ceased to serve in such capacity.

     6.  No Duplication of Payments.  The Company shall not be liable under this
         --------------------------
Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise payable hereunder.

     7.  Partial Indemnification.  If Indemnitee is entitled under any
         -----------------------
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however,
for all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     8.  Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
         ---------------------
that in certain instances, federal law or applicable public policy may
prohibit the Company from indemnifying its directors, officers, employees,
agents or fiduciaries under this Agreement or otherwise. Indemnitee
understands and acknowledges that the Company has undertaken or may be
required in the future to undertake with the Securities and Exchange
Commission to submit the question of indemnification to a court in certain
circumstances for a determination of the Company's right under public policy
to indemnify Indemnitee.

     9.  Liability Insurance.  To the extent the Company maintains liability
         -------------------
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.

     10.  Exceptions.  Notwithstanding any other provision of this Agreement,
          ----------
the Company shall not be obligated pursuant to the terms of this Agreement:

                                     -7-
<PAGE>

         (a)  Excluded Actions or Omissions.  To indemnify or make Expense
              -----------------------------
Advances to Indemnitee with respect to Claims arising out of acts, omissions
or transactions for which Indemnitee is prohibited from receiving
indemnification under applicable law.

         (b)  Claims Initiated by Indemnitee.  To indemnify or make Expense
              ------------------------------
Advances to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, counterclaim or crossclaim, except
(i) with respect to actions or proceedings brought to establish or enforce a
right to indemnification under this Agreement or any other agreement or
insurance policy or under the Company's Certificate of Incorporation or Bylaws
now or hereafter in effect relating to Claims for Covered Events, (ii) in
specific cases if the Board of Directors has approved the initiation or
bringing of such Claim, or (iii) as otherwise required under Section 145 of
the Delaware General Corporation Law, regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification, Expense
Advances, or insurance recovery, as the case may be.

         (c)  Lack of Good Faith.  To indemnify Indemnitee for any Expenses
              ------------------
incurred by the Indemnitee with respect to any action instituted (i) by
Indemnitee to enforce or interpret this Agreement, if a court having
jurisdiction over such action determines as provided in Section 13 that each
of the material assertions made by the Indemnitee as a basis for such action
was not made in good faith or was frivolous, or (ii) by or in the name of the
Company to enforce or interpret this Agreement, if a court having jurisdiction
over such action determines as provided in Section 13 that each of the
material defenses asserted by Indemnitee in such action was made in bad faith
or was frivolous.

         (d)  Claims Under Section 16(b).  To indemnify Indemnitee for Expenses
              --------------------------
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of
1934, as amended, or any similar successor statute.

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs
and personal and legal representatives. The Company shall require and cause
any successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part,
of the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company
would be required to perform if no such succession had taken place. This
Agreement shall continue in effect regardless of whether Indemnitee continues
to serve as a director, officer, employee, agent or fiduciary (as applicable)
of the Company or of any other enterprise at the Company's request.

     13.  Expenses Incurred in Action Relating to Enforcement or
          ------------------------------------------------------
Interpretation.  In the event that any action is instituted by Indemnitee under
--------------
this Agreement or under any liability insurance policies maintained by the
Company to enforce or interpret any of the terms hereof or thereof,

                                     -8-
<PAGE>

Indemnitee shall be entitled to be indemnified for all Expenses incurred by
Indemnitee with respect to such action (including without limitation
attorneys' fees), regardless of whether Indemnitee is ultimately successful in
such action, unless as a part of such action a court having jurisdiction over
such action makes a final judicial determination (as to which all rights of
appeal therefrom have been exhausted or lapsed) that each of the material
assertions made by Indemnitee as a basis for such action was not made in good
faith or was frivolous; provided, however, that until such final judicial
determination is made, Indemnitee shall be entitled under Section 3 to receive
payment of Expense Advances hereunder with respect to such action. In the
event of an action instituted by or in the name of the Company under this
Agreement to enforce or interpret any of the terms of this Agreement,
Indemnitee shall be entitled to be indemnified for all Expenses incurred by
Indemnitee in defense of such action (including without limitation costs and
expenses incurred with respect to Indemnitee's counterclaims and cross-claims
made in such action), unless as a part of such action a court having
jurisdiction over such action makes a final judicial determination (as to
which all rights of appeal therefrom have been exhausted or lapsed) that each
of the material defenses asserted by Indemnitee in such action was made in bad
faith or was frivolous; provided, however, that until such final judicial
determination is made, Indemnitee shall be entitled under Section 3 to receive
payment of Expense Advances hereunder with respect to such action.

     14.  Period of Limitations.  No legal action shall be brought and no
          ---------------------
cause of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a
legal action within such two year period; provided, however, that if any
                                          --------  -------
shorter period of limitations is otherwise applicable to any such cause of
action, such shorter period shall govern.

     15.  Notice.  All notices, requests, demands and other communications
          ------
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic, certified or registered mail with
postage prepaid, on the third business day after the date postmarked.
Addresses for notice to either party are as shown on the signature page of
this Agreement, or as subsequently modified by written notice.

     16.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

     17.  Severability.  The provisions of this Agreement shall be severable
          ------------
in the event that any of the provisions hereof (including any provision within
a single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including without limitation each portion of this Agreement containing any
provision held to be invalid, void or otherwise

                                     -9-
<PAGE>

unenforceable, that is not itself invalid, void or unenforceable) shall be
construed so as to give effect to the intent manifested by the provision held
invalid, illegal or unenforceable.

     18.  Choice of Law.  This Agreement, and all rights, remedies, liabilities,
          -------------
powers and duties of the parties to this Agreement, shall be governed by and
construed in accordance with the laws of the State of Delaware as applied to
contracts between Delaware residents entered into and to be performed entirely
in the State of Delaware without regard to principles of conflicts of laws.

     19.  Subrogation.  In the event of payment under this Agreement, the
          -----------
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Company effectively to bring suit to enforce such rights.

     20.  Amendment and Termination.  No amendment, modification, termination or
          -------------------------
cancellation of this Agreement shall be effective unless it is in writing signed
by both the parties hereto.  No waiver of any of the provisions of this
Agreement shall be deemed to be or shall constitute a waiver of any other
provisions hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver.

     21.  Integration and Entire Agreement.  This Agreement sets forth the
          --------------------------------
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

     22.  No Construction as Employment Agreement.  Nothing contained in this
          ---------------------------------------
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or affiliated entities.

such constituent corporation if its separate existence had continued.

         (e)  "Covered Event" shall mean any event or occurrence related to

     2.  Indemnification.
         ---------------

         (a)  Indemnification of Expenses.  Subject to the provisions of
              ---------------------------
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to the
fullest extent permitted by law if Indemnitee was or is or becomes a party to
or witness or other participant in, or is threatened to be made a party to or
witness or other participant in, any Claim (whether by reason of or arising in
part out of a Covered Event), including all interest, assessments and other
charges paid or payable in connection with or in respect of such Expenses.

         (b)  Review of Indemnification Obligations.  Notwithstanding the
              -------------------------------------
foregoing, in the event any Reviewing Party shall have determined (in a
written opinion, in any case in which Independent Legal Counsel is the
Reviewing Party) that Indemnitee is not entitled to be indemnified hereunder
under applicable law, (i) the Company shall have no further obligation under
Section 2(a) to make any payments to Indemnitee not made prior to such
determination by such Reviewing Party, and (ii) the Company shall be entitled
to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company)
for all Expenses theretofore paid to Indemnitee to which Indemnitee is not
entitled hereunder under applicable law; provided, however, that if
                                         --------  -------
Indemnitee has commenced or thereafter commences legal proceedings in a court
of competent jurisdiction to secure a determination that Indemnitee is
entitled to be indemnified hereunder under applicable law, any determination
made by any Reviewing Party that Indemnitee is not entitled to be indemnified
hereunder under applicable law shall not be binding and Indemnitee shall not
be required to reimburse the Company for any Expenses theretofore paid in
indemnifying Indemnitee until a final judicial determination is made with
respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed). Indemnitee's obligation to reimburse the Company for any
Expenses shall be unsecured and no interest shall be charged thereon.

                                     -3-
<PAGE>

         (c)  Indemnitee Rights on Unfavorable Determination; Binding Effect.
              --------------------------------------------------------------
If any Reviewing Party determines that Indemnitee substantively is not
entitled to be indemnified hereunder in whole or in part under applicable law,
Indemnitee shall have the right to commence litigation seeking an initial
determination by the court or challenging any such determination by such
Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and, subject to the provisions of Section 15, the Company hereby
consents to service of process and to appear in any such proceeding. Absent
such litigation, any determination by any Reviewing Party shall be conclusive
and binding on the Company and Indemnitee.

         (d)  Selection of Reviewing Party; Change in Control.  If there has
              -----------------------------------------------
not been a Change in Control, any Reviewing Party shall be selected by the
Board of Directors, and if there has been such a Change in Control (other than
a Change in Control which has been approved by a majority of the Company's
Board of Directors who were directors immediately prior to such Change in
Control), any Reviewing Party with respect to all matters thereafter arising
concerning the rights of Indemnitee to indemnification of Expenses under this
Agreement or any other agreement or under the Company's Certificate of
Incorporation or Bylaws as now or hereafter in effect, or under any other
applicable law, if desired by Indemnitee, shall be Independent Legal Counsel
selected by Indemnitee and approved by the Company (which approval shall not
be unreasonably withheld). Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be entitled to be indemnified hereunder under applicable law
and the Company agrees to abide by such opinion. The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to
indemnify fully such counsel against any and all expenses (including
attorneys' fees), claims, liabilities and damages arising out of or relating
to this Agreement or its engagement pursuant hereto. Notwithstanding any other
provision of this Agreement, the Company shall not be required to pay Expenses
of more than one Independent Legal Counsel in connection with all matters
concerning a single Indemnitee, and such Independent Legal Counsel shall be
the Independent Legal Counsel for any or all other Indemnitees unless (i) the
employment of separate counsel by one or more Indemnitees has been previously
authorized by the Company in writing, or (ii) an Indemnitee shall have
provided to the Company a written statement that such Indemnitee has
reasonably concluded that there may be a conflict of interest between such
Indemnitee and the other Indemnitees with respect to the matters arising under
this Agreement.

         (e)  Mandatory Payment of Expenses.  Notwithstanding any other
              -----------------------------
provision of this Agreement other than Section 10 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim, Indemnitee shall be indemnified against all Expenses incurred by
Indemnitee in connection therewith.

     3.  Expense Advances.
         ----------------

         (a)  Obligation to Make Expense Advances.  Upon receipt of a written
              -----------------------------------
undertaking by or on behalf of the Indemnitee to repay such amounts if it
shall ultimately be determined that the Indemnitee is not entitled to be
indemnified therefore by the Company hereunder under applicable law, the
Company shall make Expense Advances to Indemnitee.

                                     -4-
<PAGE>

         (b)  Form of Undertaking.  Any obligation to repay any Expense Advances
              -------------------
hereunder pursuant to a written undertaking by the Indemnitee shall be
unsecured and no interest shall be charged thereon.

         (c)  Determination of Reasonable Expense Advances.  The parties agree
              --------------------------------------------
that for the purposes of any Expense Advance for which Indemnitee has made
written demand to the Company in accordance with this Agreement, all Expenses
included in such Expense Advance that are certified by affidavit of
Indemnitee's counsel as being reasonable shall be presumed conclusively to be
reasonable.

     4.  Procedures for Indemnification and Expense Advances.
         ---------------------------------------------------

         (a)  Timing of Payments.  All payments of Expenses (including without
              ------------------
limitation Expense Advances) by the Company to the Indemnitee pursuant to this
Agreement shall be made to the fullest extent permitted by law as soon as
practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than thirty (30) business days after such
written demand by Indemnitee is presented to the Company, except in the case
of Expense Advances, which shall be made no later than ten (10) business days
after such written demand by Indemnitee is presented to the Company.

         (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
              --------------------------------
condition precedent to Indemnitee's right to be indemnified or Indemnitee's
right to receive Expense Advances under this Agreement, give the Company
notice in writing as soon as practicable of any Claim made against Indemnitee
for which indemnification will or could be sought under this Agreement. Notice
to the Company shall be directed to the Chief Executive Officer of the Company
at the address shown on the signature page of this Agreement (or such other
address as the Company shall designate in writing to Indemnitee). In addition,
Indemnitee shall give the Company such information and cooperation as it may
reasonably require and as shall be within Indemnitee's power.

         (c)  No Presumptions; Burden of Proof.  For purposes of this
              --------------------------------
Agreement, the termination of any Claim by judgment, order, settlement
(whether with or without court approval) or conviction, or upon a plea of nolo
                                                                          ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
----------
did not meet any particular standard of conduct or have any particular belief
or that a court has determined that indemnification is not permitted by this
Agreement or applicable law. In addition, neither the failure of any Reviewing
Party to have made a determination as to whether Indemnitee has met any
particular standard of conduct or had any particular belief, nor an actual
determination by any Reviewing Party that Indemnitee has not met such standard
of conduct or did not have such belief, prior to the commencement of legal
proceedings by Indemnitee to secure a judicial determination that Indemnitee
should be indemnified under this Agreement under applicable law, shall be a
defense to Indemnitee's claim or create a presumption that Indemnitee has not
met any particular standard of conduct or did not have any particular belief.
In connection with any determination by any Reviewing Party or otherwise as to
whether the Indemnitee is entitled to be indemnified hereunder under
applicable law, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

                                     -5-
<PAGE>

         (d)  Notice to Insurers.  If, at the time of the receipt by the
              ------------------
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company
has liability insurance in effect which may cover such Claim, the Company
shall give prompt notice of the commencement of such Claim to the insurers in
accordance with the procedures set forth in the respective policies. The
Company shall thereafter take all necessary or desirable action to cause such
insurers to pay, on behalf of the Indemnitee, all amounts payable as a result
of such Claim in accordance with the terms of such policies.

         (e)  Selection of Counsel.  In the event the Company shall be obligated
              --------------------
hereunder to provide indemnification for or make any Expense Advances with
respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by
Indemnitee (which approval shall not be unreasonably withheld) upon the
delivery to Indemnitee of written notice of the Company's election to do so.
After delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees or expenses of separate counsel
subsequently retained by or on behalf of Indemnitee with respect to the same
Claim; provided that, (i) Indemnitee shall have the right to employ
Indemnitee's separate counsel in any such Claim at Indemnitee's expense and
(ii) if (A) the employment of separate counsel by Indemnitee has been
previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and
expenses of Indemnitee's separate counsel shall be Expenses for which
Indemnitee may receive indemnification or Expense Advances hereunder.

     5.  Additional Indemnification Rights; Nonexclusivity.
         -------------------------------------------------

         (a)  Scope.  The Company hereby agrees to indemnify the Indemnitee to
              -----
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable
law, statute or rule which expands the right of a Delaware corporation to
indemnify Indemnitee, it is the intent of the parties hereto that Indemnitee
shall enjoy by this Agreement the greater benefits afforded by such change. In
the event of any change in any applicable law, statute or rule which narrows
the right of a Delaware corporation to indemnify Indemnitee, such change, to
the extent not otherwise required by such law, statute or rule to be applied
to this Agreement, shall have no effect on this Agreement or the parties'
rights and obligations hereunder except as set forth in Section 10(a) hereof.

         (b)  Nonexclusivity.  The indemnification and the payment of Expense
              --------------
Advances provided by this Agreement shall be in addition to any rights to
which Indemnitee may be entitled under the Company's Certificate of
Incorporation, its Bylaws, any other agreement, any vote of stockholders or
disinterested directors, the General Corporation Law of the State of Delaware,
or otherwise. The indemnification and the payment of Expense Advances provided
under this Agreement shall continue as to Indemnitee for any action taken or
not taken while serving in an indemnified capacity even though subsequent
thereto Indemnitee may have ceased to serve in such capacity.

                                     -6-
<PAGE>

     6.  No Duplication of Payments.  The Company shall not be liable under this
         --------------------------
Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise payable hereunder.

     7.  Partial Indemnification.  If Indemnitee is entitled under any
         -----------------------
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however,
for all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     8.  Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
         ---------------------
that in certain instances, federal law or applicable public policy may
prohibit the Company from indemnifying Indemnitee under this Agreement or
otherwise. Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the Securities
and Exchange Commission to submit the question of indemnification to a court
in certain circumstances for a determination of the Company's right under
public policy to indemnify Indemnitee.

     9.  Liability Insurance.  To the extent the Company maintains liability
         -------------------
insurance applicable to entities similarly situated as Indemnitee, Indemnitee
shall be covered by such policies in such a manner as to provide Indemnitee the
same rights and benefits as are provided to the most favorably insured of the
entities similarly situated as Indemnitee.

     10.  Exceptions.  Notwithstanding any other provision of this Agreement,
          ----------
the Company shall not be obligated pursuant to the terms of this Agreement:

         (a)  Excluded Actions or Omissions.  To indemnify or make Expense
              -----------------------------
Advances to Indemnitee with respect to Claims arising out of acts, omissions
or transactions for which Indemnitee is prohibited from receiving
indemnification under Section 145 of the Delaware General Corporation Law or
other applicable law.

         (b)  Claims Initiated by Indemnitee.  To indemnify or make Expense
              ------------------------------
Advances to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, counterclaim or crossclaim, except
(i) with respect to actions or proceedings brought to establish or enforce a
right to indemnification under this Agreement or any other agreement or
insurance policy or under the Company's Certificate of Incorporation or Bylaws
now or hereafter in effect relating to Claims for Covered Events, (ii) in
specific cases if the Board of Directors has approved the initiation or
bringing of such Claim, or (iii) as otherwise required under Section 145 of
the Delaware General Corporation Law, regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification, Expense
Advances, or insurance recovery, as the case may be.

         (c)  Lack of Good Faith.  To indemnify Indemnitee for any Expenses
              ------------------
incurred by the Indemnitee with respect to any action instituted (i) by
Indemnitee to enforce or interpret this Agreement, if a court having
jurisdiction over such action determines as provided in Section 13 that each
of the material assertions made by the Indemnitee as a basis for such action
was not made in good faith or was frivolous, or (ii) by or in the name of the
Company to enforce or interpret this

                                     -7-
<PAGE>

Agreement, if a court having jurisdiction over such action determines as
provided in Section 13 that each of the material defenses asserted by
Indemnitee in such action was made in bad faith or was frivolous.

         (d)  Claims Under Section 16(b).  To indemnify Indemnitee for
              --------------------------
Expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs
and personal and legal representatives. The Company shall require and cause
any successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part,
of the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company
would be required to perform if no such succession had taken place.

     13.  Expenses Incurred in Action Relating to Enforcement or
          ------------------------------------------------------
Interpretation.  In the event that any action is instituted by Indemnitee
--------------
under this Agreement or under any liability insurance policies maintained by
the Company to enforce or interpret any of the terms hereof or thereof,
Indemnitee shall be entitled to be indemnified for all Expenses incurred by
Indemnitee with respect to such action (including without limitation
attorneys' fees), regardless of whether Indemnitee is ultimately successful in
such action, unless as a part of such action a court having jurisdiction over
such action makes a final judicial determination (as to which all rights of
appeal therefrom have been exhausted or lapsed) that each of the material
assertions made by Indemnitee as a basis for such action was not made in good
faith or was frivolous; provided, however, that until such final judicial
determination is made, Indemnitee shall be entitled under Section 3 to receive
payment of Expense Advances hereunder with respect to such action. In the
event of an action instituted by or in the name of the Company under this
Agreement to enforce or interpret any of the terms of this Agreement,
Indemnitee shall be entitled to be indemnified for all Expenses incurred by
Indemnitee in defense of such action (including without limitation costs and
expenses incurred with respect to Indemnitee's counterclaims and cross-claims
made in such action), unless as a part of such action a court having
jurisdiction over such action makes a final judicial determination (as to
which all rights of appeal therefrom have been exhausted or lapsed) that each
of the material defenses asserted by Indemnitee in such action was made in bad
faith or was frivolous; provided, however, that until such final judicial
determination is made, Indemnitee shall be entitled under Section 3 to receive
payment of Expense Advances hereunder with respect to such action.

     14.  Period of Limitations.  No legal action shall be brought and no
          ---------------------
cause of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of

                                     -8-
<PAGE>

accrual of such cause of action, and any claim or cause of action of the
Company shall be extinguished and deemed released unless asserted by the
