applicable law. The parties also intend for the Merger to be treated as a

accounting purposes.

        B. The Boards of Directors of Shockwave and Atom have determined that
the Merger is in the best interests of their respective companies and
shareholders, have approved the Merger and, accordingly, have agreed to effect
the Merger provided for herein upon the terms and conditions of this Agreement.

irrevocably vote all shares of Atom capital stock owned by such Atom Shareholder
in favor of this Agreement, the Merger, the Restated Articles of Incorporation
and the other transactions contemplated by this Agreement (the "ATOM REQUIRED
APPROVALS"), and an investment representation letter in the form and substance
of Exhibit B attached hereto under which each such Atom Shareholder will provide
certain representations and warranties to Shockwave (the "INVESTMENT
REPRESENTATION LETTER").

Shockwave Shareholders holding a majority of the outstanding shares of (i)
Shockwave Common Stock and Shockwave Preferred Stock, (ii) Shockwave Preferred
Stock, (iii) Shockwave Series A Preferred Stock, and (iv) Shockwave Series B
Preferred Stock will execute and deliver to Shockwave a voting agreement in the
form and substance of Exhibit C attached hereto (the "SHOCKWAVE VOTING
AGREEMENT") under which each such Shockwave Shareholder will agree to
irrevocably vote all shares of Shockwave capital stock owned by such Shockwave
Shareholder in favor of this Agreement, the Merger, the amendment and

the Surviving Corporation, with one of the initial directors for the Atom

(the "FIRST RESTATED VOTING AGREEMENT") to set forth the terms of such

Stock held by an Atom Shareholder that is issued and outstanding immediately
prior to the Effective Time will, by virtue of the Merger and without the need
for any further action on the part of the holder thereof (except as expressly

Conversion Number. The preceding provisions of this Section 2.1(c) are subject

(regarding the withholding of Escrow Shares).

               (d) Conversion of Atom Series C Preferred Stock. Subject to the
terms and conditions of this Agreement, at the Effective Time, each share of
Atom Series C Preferred Stock held by an Atom Shareholder that is issued and
outstanding immediately prior to the Effective Time will, by virtue of the
Merger and without the need for any further action on the part of the holder

               (e) Fractional Shares. No fractional shares of Shockwave Common
Stock or Shockwave Preferred Stock will be issued in connection with the Merger.
In lieu thereof, each holder of Atom Common Stock or Atom Preferred Stock who
would otherwise be entitled to receive a fraction of a share of Shockwave Common
Stock, Shockwave Series C-1 Preferred Stock, Shockwave Series C-2 Preferred
Stock or Shockwave Series C-3 Preferred Stock pursuant to Section 2.1, computed
after aggregating, for each class or series, all shares of Shockwave Common
Stock, Shockwave Series C-1 Preferred Stock, Shockwave Series C-2 Preferred
Stock or Shockwave Series C-3 Preferred Stock to be received by such holder
pursuant to Section 2.1, will instead receive from Shockwave, upon surrender of
such holder's Atom Certificates pursuant to Article 7, an amount of cash

the fair market value per share on the Closing Date, as determined in good faith
by the Board of Directors of Shockwave, of the Shockwave Common Stock, Shockwave
Series C-1 Preferred Stock, Shockwave Series C-2 Preferred Stock or Shockwave
Series C-3 Preferred Stock (as adjusted to reflect any Capital Change (as

Stock, Shockwave Series C-1 Preferred Stock, Shockwave Series C-2 Preferred
Stock or Shockwave Series C-3 Preferred Stock that such holder would otherwise
have been entitled to receive.

               (f) Dissenting Shares. Holders of shares of Atom Common Stock and
Atom Preferred Stock who have complied with all requirements for perfecting
shareholders' rights of appraisal, as set forth in Chapter 23B.13 of the WBCA,
will be entitled to their rights under the WBCA with respect to such shares
("DISSENTING SHARES").

               (h) Continuation of Vesting and Repurchase Rights. If any shares
of Atom Common Stock or Atom Preferred Stock outstanding immediately prior to
the Effective Time are at the Effective Time (a) unvested or are subject to a
repurchase option, risk of forfeiture, or any other condition providing that
such shares may be forfeited to Atom upon any termination of the shareholder's
employment, directorship or other relationship with Atom (and/or any affiliate
of Atom) under the terms of any restricted stock purchase agreement, stock
option agreement


                                       7
   9

(including any stock option agreement under the Atom Plan (as defined in Section
2.3)) or other agreement with Atom ("UNVESTED ATOM SHARES"), or (b) not Unvested
Atom Shares but are otherwise subject to a contractual restriction on the
transfer of such shares ("RESTRICTED ATOM SHARES"), then such repurchase option,
risk of forfeiture, other condition or contractual restriction on transfer will
be assigned to Shockwave, and the Shockwave Merger Shares issued upon the
conversion of such Unvested Atom Shares or Restricted Atom Shares in the Merger
will continue to be unvested and will continue to be subject to the same
repurchase options, risks of forfeiture, other conditions or contractual
restrictions on transfer, as applicable, immediately following the Effective
Time as they were subject to immediately prior to the Effective Time. The
certificates representing such shares of Shockwave Common Stock will accordingly
be marked with appropriate legends noting such repurchase options, risks of
forfeiture, other conditions or contractual restrictions on transfer. Atom will
take all actions that may be necessary to ensure that, from and after the
Effective Time, Shockwave is entitled to exercise any such repurchase option or
other right set forth in any such restricted stock purchase agreement or other
agreement and to enforce any such contractual restriction on transfer.

        2.2 Adjustments for Capital Changes. Notwithstanding the provisions of
Section 2.1, if Shockwave recapitalizes, either through a subdivision (or stock
split) of any of its outstanding shares of Shockwave Common Stock or Shockwave
Preferred Stock into a greater number of such shares, or a combination (or
reverse stock split) of any of its outstanding shares of Shockwave Common Stock
or Shockwave Preferred Stock into a lesser number of such shares, or
reorganizes, reclassifies or otherwise changes its outstanding shares of
Shockwave Common Stock or Shockwave Preferred Stock into the same or a different
number of shares of other classes or series of Shockwave stock (other than
through a subdivision or combination of shares provided for in the preceding
clause), or declares a dividend or other distribution on its outstanding shares
payable in shares of Shockwave Common Stock or Shockwave Preferred Stock, in
shares or securities convertible into shares of Shockwave Common Stock,
Shockwave Preferred Stock and/or other Shockwave equity securities (each, a
"CAPITAL CHANGE"), at any time after the Agreement Date and prior to the
Effective Time, then the Atom Conversion Number will be proportionally and
equitably adjusted.

        2.3 Atom Options. At the Effective Time, all outstanding options ("ATOM
OPTIONS") to purchase Atom Common Stock, including all Atom Options granted
under the Atom 1998 Stock Option Plan (the "ATOM PLAN"), will be assumed by
Shockwave. Holders of each Atom Option so assumed by Shockwave will be entitled,
in accordance with the terms of such option, to purchase after the Effective
Time that number of shares of Shockwave Common Stock ("SHOCKWAVE OPTIONS"),
determined by multiplying the number of shares of Atom Common Stock subject to
such Atom Option at the Effective Time by the Atom Conversion Number, and the
exercise price per share for each such Shockwave Option will equal the exercise
price of the Atom Option immediately prior to the Effective Time divided by the
Atom Conversion Number. If the foregoing calculation results in a Shockwave
Option being exercisable for a fraction of a share, then the number of shares of
Shockwave Common Stock subject to such Shockwave Option will be rounded down to
the nearest whole number and the exercise price of such Shockwave Option will be
rounded up to the nearest cent. The term, exercisability, vesting schedule,
status as an "incentive stock option" under Section 422 of the Code, if
applicable, and


                                       8
   10

all other terms of the Atom Options will otherwise be unchanged, except as
provided in Section 5.11. Continuous employment with Atom will be credited to an
optionee for purposes of determining the number of shares that are vested after
the Effective Time.

        2.4 Atom Warrants. At the Effective Time, all then outstanding warrants,
exchangeable or convertible securities or rights to purchase or otherwise
acquire Atom Common Stock or Atom Preferred Stock that are exercisable or
convertible, ultimately or potentially, into Atom Common Stock or Atom Preferred
Stock ("ATOM WARRANTS") will by virtue of the Merger, and without any further
action on the part of any holder thereof, be assumed by Shockwave and converted
into a warrant or like security ("SHOCKWAVE WARRANTS") to purchase that number
of shares of Shockwave Common Stock or Shockwave Preferred Stock determined by
multiplying the number of shares of Atom Common Stock or Atom Preferred Stock
that are subject to such Atom Warrant immediately prior to the Effective Time by
the Atom Conversion Number, at an exercise price per share of such Shockwave
Common Stock or Shockwave Preferred Stock equal to the exercise price per share
of Atom Common Stock or Atom Preferred Stock that was in effect for such Atom
Warrant immediately prior to the Effective Time divided by the Atom Conversion
Number. If the foregoing calculation would result in an assumed Atom Warrant
being exercisable (a) for a fraction of a share of Shockwave Common Stock or
Shockwave Preferred Stock, then the number of shares of Shockwave Common Stock
or Shockwave Preferred Stock subject to such Shockwave Warrant will be rounded
down to the nearest whole number of shares of Shockwave Common Stock or
Shockwave Preferred Stock, or (b) for a fraction of a cent, then the exercise
price of such Atom Warrant will be rounded up to the nearest cent. The
exercisability period and other terms and conditions of the Atom Warrants will
remain unchanged.

        2.5 Escrow of Shares. At the Effective Time, Shockwave will withhold
from the Shockwave Merger Shares 10% of the Shockwave Merger Shares to be issued
to Atom Shareholders in the Merger upon conversion of their Atom Common Stock
and Atom Preferred Stock pursuant to Section 2.1, rounded down to the nearest
whole share (such withheld Shockwave Merger Shares and any dividends or
distributions received in respect of such Shockwave Merger Shares being
hereinafter referred to as the "ESCROW SHARES"), and will hold the certificates
representing such Escrow Shares as security for the Atom Shareholders'
indemnification obligations for Damages under Article 11. The Escrow Shares will
be represented by a certificate or certificates issued in the names of each Atom
Shareholder in proportion to each such shareholder's interest therein and will
be held by Shockwave, subject to the terms and conditions of Article 11, until
the Release Date (as defined in Section 11.1). The holder of the Escrow Shares
will be determined by the parties between the Agreement Date and the Closing
Date and, if such holder is a third party, then the costs and expenses relating
to such third party holder will be borne by the Atom Shareholders on a Pro Rata
Basis (as defined in Section 11.2).

        2.6 Effects of the Merger. At and upon the Effective Time of the Merger:

               (a) the separate existence of Atom will cease and Atom will be
merged with and into Shockwave, and Shockwave will be the surviving corporation
of the Merger (sometimes


                                       9
   11

hereinafter referred to as the "SURVIVING CORPORATION") pursuant to the terms of
this Agreement, the Articles of Merger and the Certificate of Merger;

               (b) the Restated Certificate of Incorporation will be the
Certificate of Incorporation of the Surviving Corporation immediately after the
Effective Time;

   12

Shareholder or other holder of Atom securities regarding the tax treatment of

        Atom represents and warrants to Shockwave that, except as set forth in
the letter addressed to Shockwave from Atom and dated as of the Agreement Date

        3.4 Capitalization of Atom.

               (a) Outstanding Securities. The authorized capital stock of Atom
consists entirely of 25,000,000 shares of Atom Common Stock, of which a total of

issued and outstanding shares of Atom Common Stock and Atom Preferred Stock held
by each of the Atom Shareholders are set forth in Schedule 3.4(a)-1 to this
Agreement. Except as expressly set forth Schedule 3.4(a)-1, no shares of Atom
Common Stock or Atom Preferred Stock are issued or outstanding. To Atom's
knowledge, each of the Atom Shareholders has good and marketable title to that
number of shares of Atom Common Stock and/or Atom Preferred Stock as set forth
beside such person's name on Schedule 3.4(a)-1, free and clear of all
Encumbrances or any restrictions on voting. An aggregate of 4,750,000 shares of

exercise price for each such Atom Option and Atom Warrant, the number of shares
or other securities covered by each such Atom Option and Atom Warrant, and the

agreement under the Atom Plan and each agreement for each Atom Option that does
not conform to the standard agreement under the Atom Plan, and true and complete
copies of each Atom Warrant, have been delivered by Atom to Shockwave or its
legal counsel, Fenwick & West LLP. The vesting or exercisability (or any other
material terms) of any Atom Option, except as disclosed in the Atom Disclosure
Letter, will not accelerate or otherwise change as a result of the execution and
delivery of this Agreement or the consummation of the Merger or the other
transactions contemplated by this Agreement or the occurrence of any subsequent
event (such as the termination of employment of the option holder following
consummation of the Merger). Except for the Non-Plan Options, no Atom Options
have been granted or are outstanding except under and pursuant to the Atom Plan.
Atom has issued convertible promissory notes with an aggregate principal amount
of $3,880,286 (the "ATOM NOTES"). Schedule 3.4(a)-3 of the Atom Disclosure
Letter lists for each person who holds an Atom Note, the name of the holder of
each such Atom Note, the principal amount of such Atom Note, and the number of
shares of Atom Preferred Stock or other securities of Atom into which such Atom
Note is convertible. True and complete copies of each Atom Note has been
delivered by Atom to Shockwave or its legal counsel.

               (b) Valid Issuance. As of the Closing Date, there will have been
no change in the authorized or outstanding capital stock of Atom as represented
in Section 3.4(a), other than as contemplated by this Agreement. All issued and
outstanding shares of Atom Common Stock and Atom Preferred Stock have been duly
authorized and validly issued, are fully paid and nonassessable, are not subject
to any preemptive right, right of first refusal, right of first offer or right
of rescission, and have been offered, issued, sold and delivered by Atom in
compliance with (i) all registration or qualification requirements (or
applicable exemptions therefrom) of all applicable securities laws and, to the
knowledge of Atom, other applicable Legal Requirements and (ii) all requirements
set forth in applicable agreements or instruments. All shares of Atom Common
Stock and Atom Preferred Stock subject to issuance under Atom Options and Atom


                                       13
   15

Warrants, upon issuance on the terms and conditions specified in the instruments
pursuant to which they are issuable, will be duly authorized, validly issued,
fully paid and nonassessable. All outstanding Atom Options and Atom Warrants
have been issued and granted in compliance with (i) all registration or
qualification requirements (or applicable exemptions therefrom) of all
applicable securities laws and, to the knowledge of Atom, other applicable Legal
Requirements and (ii) all requirements set forth in applicable agreements or
instruments.

               (c) No Other Options, Warrants or Rights. Other than as set forth
in Section 3.4(a), there are no options, warrants, convertible securities or
other securities, calls, commitments, conversion privileges, preemptive rights,

obligating Atom to grant, issue, extend, or enter into any such option, warrant,
convertible security or other security, call, commitment, conversion privilege,
preemptive right, right of first refusal, right of first offer or other right or
agreement, and there is no liability for dividends accrued but unpaid.

               (d) No Voting Arrangements or Registration Rights. Except as
contemplated by this Agreement, there are no voting agreements, voting trusts or
proxies applicable to any of Atom's outstanding capital stock or any Atom
Options or to the conversion of any shares of Atom's capital stock in the Merger
pursuant to any agreement or obligation to which Atom is a party or, to Atom's
knowledge, pursuant to any other agreement or obligation. Atom is not under any
obligation to register under the Securities Act any of its presently outstanding
shares of stock or other securities or any stock or other securities that may be
subsequently issued.

        3.5 No Conflict. Neither the execution and delivery of this Agreement
nor any of the Atom Ancillary Agreements by Atom, nor the consummation of the
Merger or the other transactions contemplated hereby or thereby, will conflict
with, or (with or without notice or lapse of time, or both) result in a
termination, breach, impairment or violation of, or constitute a default under:
(a) any provision of the Articles of Incorporation or Bylaws of Atom as
currently in effect; (b) any material federal, state, local or foreign judgment,
writ, decree, order, statute, rule or regulation applicable to Atom or any of
its material assets or properties; or (c) any material instrument, agreement,
contract, undertaking, understanding, letter of intent, memorandum of
understanding or commitment (whether verbal or in writing) to which Atom is a
party or by which Atom or any of its material assets or properties are bound. To
Atom's knowledge, neither Atom's entering into this Agreement nor the
consummation of the Merger or the other transactions contemplated by this
Agreement will give rise to, or trigger the application of, any rights of any
third party that would come into effect upon the effectiveness of the Merger.
The consummation of the Merger by Atom will not require the consent, release,
waiver or approval of any third party (including the consent of any party
required to be obtained in order to keep any agreement between such party and
Atom in effect following the Merger or to provide that Atom is not in breach or
violation of any such agreement following the Merger), other than the approval
of this Agreement and the Merger by Atom Shareholders under the WBCA.


                                       14

        3.6 Litigation. There is no action, suit, arbitration, mediation,
proceeding, claim or investigation pending against Atom (or against any officer,
director, employee or agent of Atom in their capacity as such or relating to
their employment, services or relationship with Atom) before any Governmental
Authority or arbitrator, nor, to Atom's knowledge, has any such action, suit,
arbitration, mediation, proceeding, claim or investigation been threatened.
There is no judgment, decree, injunction, rule or order of any Governmental
Authority or arbitrator outstanding against Atom. To Atom's knowledge, there is
no basis for any person to assert a claim against Atom based upon: (a) Atom's
entering into this Agreement or any Atom Ancillary Agreement or consummating the
Merger or the other transactions contemplated by this Agreement, any Atom
Ancillary Agreement; or (b) a claim of ownership of, or options, warrants or
other rights to acquire ownership of, any shares of the capital stock of Atom or
any rights as an Atom shareholder, including any option, warrant or preemptive
rights or rights to notice or to vote, other than for the rights of the Atom
Shareholders with respect to the Atom Common Stock and Atom Preferred Stock
shown as being owned by such persons on Schedule 3.4(a)-1 of the Atom Disclosure
Letter and the rights of holders of Atom Options and Atom Warrants shown as
being owned by such persons on Schedule 3.4(a)-2 of the Atom Disclosure Letter.

        3.7 Taxes.

               (a) Atom has timely filed all federal, state, local and foreign
tax and information returns required to be filed by it, has timely paid all
taxes required to be paid by it for which payment is due, has established an
adequate accrual or reserve for the payment of all taxes payable in respect of
the periods or portions thereof prior to the Closing Date subsequent to the
periods covered by its most recent applicable tax returns (which accrual or
reserve as of the Balance Sheet Date (as defined in Section 3.8) is fully
reflected on the Balance Sheet and in any more recent balance sheet of Atom
provided by Atom to Shockwave on or before the Agreement Date), has made all
necessary estimated tax payments, and has no liability for taxes in excess of
the amount so paid or accruals or reserves so established. All such returns and
reports are true, correct and complete, and Atom has provided Shockwave with
true and correct copies of such returns and reports. Atom is not delinquent in
the payment of any tax or in the filing of any tax returns, and no deficiencies
for any tax have been threatened, claimed, proposed or assessed against Atom or
any of the officers, employees or agents of Atom in their capacity as such. Atom
has not received any notification from the Internal Revenue Service or any other
taxing authority regarding any material issues that: (i) are currently pending
before the Internal Revenue Service or any other taxing authority (including but
not limited to any sales or use tax authority) regarding Atom, or (ii) have been
raised by the Internal Revenue Service or other taxing authority and not yet
finally resolved. No tax return of Atom is under audit by the Internal Revenue
Service or any state or local taxing agency or authority and any such past
audits (if any) have been completed and fully resolved to the satisfaction of
the applicable tax authority conducting such audit and all taxes determined by
such audit to be due from Atom have been paid in full to the applicable taxing
authorities. No tax liens are currently in effect against any assets of Atom
other than liens which arise by operation of law for taxes not yet due and
payable. There is not in effect any waiver by Atom of any statute of limitations
with respect to any taxes; and Atom has not consented to extend the due date for
which any tax may be assessed or collected by any taxing authority. Atom is not
a "personal holding company" within the


                                       15
   17

meaning of the Code. Atom has withheld with respect to each of its employees and
independent contractors all taxes, including but not limited to federal and
state income taxes, FICA, Medicare, FUTA and other taxes, required to be
withheld, and paid such withheld amounts to the appropriate tax authority within
the time prescribed by law. Since its inception, Atom has not been a "United
States real property holding corporation," as defined in Section 897(c)(2) of
the Code, and in Section 1.897-2(b) of the Treasury Regulations issued
thereunder (the "REGULATIONS"), and Atom has filed, or at the Effective Time
will file, with the Internal Revenue Service all statements, if any, which are
required under Section 1.897-2(h) of the Regulations. Atom has not been
distributed in a transaction qualifying under Section 355 of the Code within the
last two years, nor has Atom distributed any corporation in a transaction
qualifying under Section 355 of the Code within the last two years. Atom has not
elected pursuant to the Code to be treated as an "S" corporation or a
collapsible corporation pursuant to Section 1362(a) or Section 341(f) of the
Code. Atom will not, as a result of any action taken prior to the Effective
Time, have any adjustment under Section 481 of the Code for periods after the
Effective Time.

               (b) For the purposes of this Section, the terms "TAX" and "TAXES"
include all federal, state, local and foreign income, alternative or add-on
minimum income, gains, franchise, excise, property, property transfer, sales,
use, employment, license, payroll, ad valorem, documentary, stamp, withholding,
occupation, recording, value added or transfer taxes, governmental charges,
fees, customs duties, levies or assessments (whether payable directly or by
withholding), and, with respect to any such taxes, any estimated tax, interest,
fines and penalties or additions to tax and interest on such fines, penalties
and additions to tax.

        3.8 Atom Financial Statements. Attached as Schedule 3.8 to the Atom
Disclosure Letter are Atom's audited balance sheet as of December 31, 1999, its
audited consolidated statements of operations, statements of cash flows and
statements of changes in shareholders' equity for the year ended December 31,
1999, its unaudited balance sheet of Atom as of October 31, 2000, and its
unaudited consolidated statements of operations, statements of cash flows and
statements of changes in shareholders' equity for the ten-months ended October
31, 2000 (all such financial statements of Atom and any notes thereto are
hereinafter collectively referred to as the "ATOM FINANCIAL STATEMENTS"). The
Atom Financial Statements: (a) are derived from and are in accordance with the
books and records of Atom, (b) fairly present the financial condition of Atom at
the dates therein indicated and the results of operations for the periods
therein specified, and (c) have been prepared in accordance with United States
generally accepted accounting principles ("GAAP") applied on a basis consistent
with prior periods except for any absence of notes with respect to the unaudited
Atom Financial Statements. Atom has no material debt, liability or obligation of
any nature, whether accrued, absolute, contingent or otherwise, and whether due
or to become due, except for (a) those shown on Atom's unaudited balance sheet
as of October 31, 2000 included in the Atom Financial Statements (the "BALANCE
SHEET"), and (b) those that may have been incurred after October 31, 2000 the
"BALANCE SHEET DATE") in the ordinary course of Atom's business consistent with
its past practices, and that are not material in amount, either individually or
collectively. All reserves established by Atom that are set forth in or
reflected in the Balance Sheet are adequate. At the Balance Sheet Date, there
were no material loss contingencies (as such term is used in Statement of
Financial Accounting Standards No. 5 issued by the Financial Accounting
Standards Board in March 1975) which are


                                       16
   18

not adequately provided for in the Balance Sheet as required by said Statement
No. 5. The Atom Financial Statements comply in all material respects with the
American Institute of Certified Public Accountants' Statement of Position 97-2,
as amended.

        3.9 Title to Properties. Atom has good and marketable title to all of
its assets and properties (including those shown on the Balance Sheet), free and
clear of all Encumbrances, other than liens for current taxes that are not yet
due and payable and except for liens which in the aggregate do not secure more
than $10,000 in liabilities. All machinery, vehicles, equipment and other
tangible personal property owned or leased by Atom or used in its business are
in good condition and repair, normal wear and tear excepted, and all leases of
real or personal property to which Atom is a party are fully effective and
afford Atom, as applicable, peaceful and undisturbed leasehold possession of the
real or personal property that is the subject of the lease. To its knowledge,
Atom is not in material violation of any zoning, building, safety or
environmental ordinance, regulation or requirement or other law or regulation
applicable to the operation of its owned or leased properties, nor has Atom
received any notice of violation of law with which it has not complied. Atom
does not own any real property. Schedule 3.9 to the Atom Disclosure Letter sets
forth a complete and accurate list and a brief description of all personal
property owned or leased by Atom with an individual value of $10,000 or greater.

        3.10 Absence of Certain Changes. Since the Balance Sheet Date, Atom has
operated its business in the ordinary course consistent with its past practice,
and since such date there has not been with respect to Atom any:

               (a) Material Adverse Change;

               (b) amendment or change in the Articles of Incorporation or
Bylaws or other charter documents;

               (c) incurrence, creation or assumption by Atom of (i) any

any right to repurchase shares of Atom's capital stock upon the shareholder's
termination of employment or services with Atom or pursuant to any right of
first refusal;

               (f) payment or discharge by Atom of any Encumbrance on any asset
or property of Atom, or the payment or discharge of any liability of Atom, in
each case that was not either shown on the Balance Sheet or incurred in the
ordinary course of Atom's business after the


                                       17
   19

Balance Sheet Date in an amount not in excess of $10,000 for any single
liability to a particular creditor;

               (g) purchase, license, sale, assignment or other disposition or
transfer, or any agreement or other arrangement for the purchase, license, sale,
assignment or other disposition or transfer, of any of the assets, properties or
goodwill of Atom other than a license of any product or products of Atom made in
the ordinary course of Atom's business consistent with its past practice;

a Material Adverse Effect on Atom;

               (i) declaration, setting aside or payment of any dividend on, or

any direct or indirect redemption, purchase or other acquisition of any capital
stock of Atom or any change in any rights, preferences, privileges or
restrictions of any outstanding security of Atom;

               (j) change or increase in the compensation payable or to become
payable to any of the officers, directors, or employees of Atom, or in any bonus
or pension, insurance or other benefit payment or arrangement (including stock
awards, stock option grants, stock appreciation rights or stock option grants)
made to or with any of such officers, employees or agents except in connection
with normal employee salary or performance reviews or otherwise in the ordinary
course of Atom's business consistent with its past practice and except as
contemplated in this Agreement;

               (k) change with respect to the management, supervisory or other
key personnel of Atom;

               (l) obligation or liability incurred by Atom to any of its
officers, directors or shareholders, except for normal and customary
compensation and expense allowances payable to officers in the ordinary course
of Atom's business consistent with its past practice;

               (m) making by Atom of any loan, advance or capital contribution
to, or any investment in, any officer, director or shareholder of Atom or any

material interest at the time of such loan, advance, capital contribution or
investment;

               (n) entering into, amendment of, relinquishment, termination or
non-renewal by Atom of any contract, lease, transaction, commitment or other
right or obligation other than in the ordinary course of its business consistent
with its past practice; or any written or oral indication or assertion by the
other party thereto of any material problems with Atom's services or performance
under such contract, lease, transaction, commitment or other right or obligation

Except as set forth in Schedule 3.12 to the Atom Disclosure Letter, no consent,

Effective Time, any Atom Material Agreement will continue to be in full force
and effect without any breach or violation thereof caused by virtue of the

exists, that (with or without notice or lapse of time) will, or would reasonably

Material Agreement, (ii) the right to a rebate, chargeback, penalty or change in
delivery schedule under any Atom Material Agreement, (iii) the right to
accelerate the maturity or performance of any obligation of Atom under any Atom

reasonably be expected to have individually or in the aggregate a Material
Adverse Effect on Atom. Atom has not received any notice or other communication
regarding any actual or possible violation or breach of, or default under, any
Atom Material Agreement.

               (a) To Atom's knowledge, Atom owns, or has the valid right or
license to use, possess, sell, license, copy, distribute, market, advertise
and/or dispose of all Intellectual Property (as defined below) to the extent
necessary or required for the conduct of the business of Atom as presently
conducted and as presently proposed to be conducted by Atom (such Intellectual
Property being hereinafter collectively referred to as the "ATOM IP RIGHTS"),
and such rights to use, possess, sell, license, copy, distribute, market,
advertise and/or dispose of are


                                       21

               (b) Neither the execution, delivery and performance of this
Agreement nor the consummation of the Merger and the other transactions
contemplated by this Agreement will: (a) constitute a material breach of or
default under any instrument, contract, license or other agreement governing any
Atom IP Right to which Atom is a party (collectively, the "ATOM IP RIGHTS
AGREEMENTS"); (b) cause the forfeiture or termination of, or give rise to a
right of forfeiture or termination of, any Atom IP Right; or (c) materially
impair the right of Atom or Shockwave as the Surviving Corporation to use,
possess, sell or license any Atom IP Right or portion thereof.

               (c) To Atom's knowledge, Atom has ownership or license rights
necessary in order to manufacture, market, license, sell or furnish, or for the
intended use of, any product or service currently licensed, utilized, sold,
provided or furnished by Atom or currently under development by Atom; and, to
Atom's knowledge, there is no pending or threatened, claim or litigation
contesting the validity, ownership or right of Atom to use, possess, sell,
market, advertise, license or dispose of any Atom IP Right nor, to the knowledge
of Atom, is there any basis for any such claim, nor has Atom received any notice
asserting that any Atom IP Right or the proposed use, sale, license or
disposition thereof conflicts or will conflict with the rights of any other
party, nor, to the knowledge of Atom, is there any basis for any such assertion.

               (d) To Atom's knowledge, no current or former employee,
consultant or independent contractor of Atom: (i) is in material violation of
any term or covenant of any employment contract, patent disclosure agreement,
invention assignment agreement, non-disclosure agreement, noncompetition
agreement or any other contract or agreement with any other party, in each case
where the subject of which is Intellectual Property, by virtue of such
employee's, consultant's, or independent contractor's being employed by, or
performing services for, Atom or using trade secrets or proprietary information
of others without permission; or (ii) has developed any technology, software or
other copyrightable, patentable, or otherwise proprietary work for Atom that is
subject to any agreement under which such employee, consultant or independent
contractor has assigned or otherwise granted to any third party any rights
(including Intellectual Property) in or to such technology, software or other
copyrightable, patentable or otherwise proprietary work or any Intellectual
Property related thereto. To Atom's


                                       22
   24

knowledge, the employment of any employee of Atom or the use by Atom of the
services of any consultant or independent contractor does not subject Atom to
any liability to any third party.

               (e) Other than agreements listed in Schedule 3.13(e) to the Atom
Disclosure Letter, there are no and will be no royalties, honoraria, fees or
other payments payable by Atom to any third person (other than salaries payable
to employees and amounts payable to independent contractors not contingent on or
related to use of their work product) pursuant to agreements in effect as of the
Effective Time by reason of the ownership, use, possession, license, copying,
modifying, making derivative works of, sale, marketing, advertising and/or
disposition of any Atom IP Rights by Atom before or after the Closing Date, and
none will become payable as a result of the consummation of the Merger or the
other transactions contemplated by this Agreement.

               (f) Atom has taken all commercially reasonably and appropriate
steps to protect, preserve and maintain the secrecy and confidentiality of the
Atom IP Rights constituting reasonably protectible trade secrets and all Atom's
ownership interests and proprietary rights therein. All officers, employees and
consultants of Atom have executed and delivered to Atom an agreement regarding
the protection of such proprietary information and the assignment of inventions
to Atom; and copies of all such agreements have been delivered to Shockwave's
counsel. Atom has secured valid written assignments from all consultants,
contractors and employees who were involved in, or who contributed to, the
creation or development of any Atom IP Rights, of the rights to such
contributions that may be owned by such persons or that Atom does not already
own by operation of law. No current or former employee, officer, director,
consultant or independent contractor of Atom has any right, license, claim or
interest whatsoever in or with respect to any Atom IP Rights.

Disclosure Letter contains a true and complete list of (i) all worldwide
registrations made by or on behalf of Atom of any patents, copyrights, mask
works, trademarks, service marks, Internet domain names or Internet or World

written governmental actions made or taken pursuant to federal, state and

unregistered copyrights, trademarks and service marks owned by Atom used in
connection with the business of Atom as presently conducted or contemplated. To

medical claims through such health plan during the twelve months preceding the
Agreement Date for more than $20,000 in the aggregate.

               (e) There has been no amendment to, written interpretation or
announcement (whether or not written) by Atom relating to, or change in employee
participation or coverage under, any Atom Benefit Arrangement that would
increase materially the expense of maintaining such Atom Benefit Arrangement
above the level of the expense incurred in respect thereof during the calendar
year 1999.

               (f) The group health plans (as defined in Section 4980B(g) of the
Code) that benefit employees of Atom are in compliance, in all respects, with
the continuation coverage requirements of Section 4980B of the Code as such
requirements affect Atom and its employees. As of the Closing Date, there will
be no material outstanding, uncorrected violations under the Consolidation
Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), with respect to
any of Atom Benefit Arrangements, covered employees, or qualified beneficiaries
that could result in a Material Adverse Effect on Atom, or in a Material Adverse
Effect on Shockwave after the Effective Time.

               (g) Unless otherwise indicated in Schedule 3.15(g) to the Atom
Disclosure Letter, no benefit payable or which may become payable by Atom
pursuant to any Atom Benefit Arrangement or as a result of or arising under this
Agreement or the other transactions contemplated by this Agreement will
constitute an "excess parachute payment" (as defined in Section 280G(b)(1) of
the Code) which is subject to the imposition of an excise Tax under Section 4999
of the Code or which would not be deductible by reason of Section 280G of the
Code. Unless otherwise indicated in Schedule 3.15(g) to the Atom Disclosure
Letter, Atom is not a party to any: (i) agreement with any employee or service
provider of Atom (A) the benefits of which are contingent, or the terms of which
are materially altered, upon the occurrence of a transaction involving Atom in
the nature of the Merger or the other transactions contemplated by this
Agreement or any Atom Ancillary Agreement, (B) providing any term of employment
or compensation guarantee, or (C) providing severance benefits or other benefits
after the termination of employment of such person regardless of the reason for
such termination of employment; or (iii) agreement or plan, including any stock
option plan, stock appreciation rights plan or stock purchase plan, any of the
benefits of which will be increased, or the vesting of benefits of which will be
accelerated, by the occurrence of the Merger or the other transactions
contemplated by this Agreement.

               (h) Except as disclosed in Schedule 3.15(h), each Atom Option was

underlying shares covered


                                       28
   30

by such option, as determined by Atom's Board of Directors after giving due
consideration to the advice of its counsel and accountants as to possible
compensation charge issues, on the date of grant. All Atom Options granted as
incentive stock options met the requirements of Section 422 of the Code on the
date of grant. All Atom Options granted to individuals who are not identified as
independent contractors may properly be accounted for under Accounting
Principles Board Opinion No. 25 and related Accounting Principles Board
amendments and interpretations.

               (i) Attached as Schedule 3.15(i) are complete and correct copies
of all policies of Atom relating to sales or commissions.

Atom with, any regulatory agency with respect to Atom, or any securities of
Atom, and all applications for such permits, orders, and consents.

        3.17 No Brokers. Other than the fees and expenses of Morgan Stanley & Co. ("MORGAN STANLEY") pursuant to the engagement letter dated May 30, 2000 (the
"ENGAGEMENT LETTER") between Atom and Morgan Stanley, a copy of which has been
delivered to Shockwave or its legal counsel, neither Atom nor any affiliate of
Atom is obligated for the payment of any fees or expenses of any investment
banker, broker, finder or similar party in connection with the origin,
negotiation or execution of this Agreement or in connection with the Merger or
any other transaction contemplated by this Agreement.

   31
               (b) Atom has devised and maintains a system of internal
accounting controls sufficient to provide reasonable assurances that: (i)
transactions are executed in accordance with management's general or specific
authorization; (ii) transactions are recorded as necessary (A) to permit
preparation of financial statements in conformity with generally accepted
accounting principles or any other criteria applicable to such statements, and
(B) to maintain accountability for assets; and (iii) the amount recorded for
assets on the books and records of Atom is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

        3.19 Insurance. Since its organization, Atom has maintained, and now
maintains, policies of insurance and bonds of the type and in amounts
customarily carried by persons conducting businesses or owning assets similar in
type and size to those of Atom, including all legally required workers'
compensation insurance and errors and omissions, casualty, fire and general
liability insurance. There is no claim pending under any of such policies or
bonds as to which coverage has been questioned, denied or disputed by the
underwriters of such policies or bonds. All premiums due and payable under all
such policies and bonds have been timely paid and Atom is otherwise in
compliance with the terms of such policies and bonds. Atom has no knowledge of
any threatened termination of, or material premium increase with respect to, any
of such policies. All policies of insurance now held by Atom are set forth in
Schedule 3.19 to Atom Disclosure Letter, together with the name of the insurer
under each policy, the type of policy, the policy coverage amount and any
applicable deductible.

        3.20 Environmental Matters.

               (a) Atom is in material compliance with all applicable
Environmental Laws (as defined below), which compliance includes the possession
by Atom of all permits and other governmental authorizations required under
applicable Environmental Laws, and compliance with the terms and conditions
thereof. Atom has not received any notice or other communication (in writing or
otherwise), whether from a governmental body, citizens groups, employee or
otherwise, that alleges that Atom is not in compliance with any Environmental
Law, and to Atom's knowledge, there are no circumstances that may prevent or
interfere with the compliance by Atom with any current Environmental Law in the
future. To Atom's knowledge, no current or prior owner of any property leased or
possessed by Atom has received any notice or other communication (in writing or
otherwise), whether from a government body, citizens group, employee or
otherwise, that alleges that such current or prior owner or Atom is not in
compliance with any Environmental Law. All governmental authorizations currently
held by Atom pursuant to any Environmental Law (if any) are identified in
Schedule 3.20 of Atom Disclosure Letter.

               (b) For purposes of this Agreement: (a) "ENVIRONMENTAL LAW" means
any federal, state or local statute, law regulation or other legal requirement
relating to pollution or protection of human health or the environment
(including ambient air, surface water, ground water, land surface or subsurface
strata), including any law or regulation relating to emissions, discharges,
releases or threatened releases of Materials of Environmental Concern, or
otherwise relating to the manufacture, processing, distribution, use, treatment,
storage, disposal, transport or handling of Materials of Environmental Concern;
and (b) "MATERIAL OF ENVIRONMENTAL



                                       30
   32
CONCERN" include chemicals, pollutants, contaminants, wastes, toxic substances,
petroleum and petroleum products and any other substance that is currently
regulated by an Environmental Law or that is otherwise a danger to health,
reproduction or the environment.

        3.21 Accounts Receivable. The receivables shown on the Balance Sheet on
the Balance Sheet Date arose in the ordinary course of business, consistent with
past practice, and have been collected or are collectible in the book amounts
thereof, less an amount not in excess of the allowance for doubtful accounts
provided for in the balance sheet of Atom on the Balance Sheet Date. Allowances
for doubtful accounts and warranty returns are adequate and have been prepared
in accordance with GAAP consistently applied and in accordance with the past
practices of Atom. The receivables of Atom arising after the Balance Sheet Date
and prior to the Closing Date arose or will arise in the ordinary course of
business, consistent with past practice, and have been collected or are
collectible in the book amounts thereof, less allowances for doubtful accounts
determined in accordance with the past practices of Atom. To the knowledge of
Atom, none of its receivables is subject to any material claim of offset,
recoupment, setoff or counter-claim and it has no knowledge of any specific
facts or circumstances (whether asserted or unasserted) that could give rise to
any such claim. No material amount of receivables are contingent upon the
performance by Atom of any obligation or contract other than normal warranty
repair and replacement. No person has any Encumbrance on any of such receivables
and no agreement for deduction or discount has been made with respect to any of
such receivables. Schedule 3.21 sets forth an aging of accounts receivable of
Atom in the aggregate and by customer, and indicates the amounts of allowances
for doubtful accounts.

        3.22 Board Actions. The Board of Directors of Atom has unanimously (a)
approved this Agreement, the Merger and all the agreements, transactions and
actions contemplated hereby, (b) determined that the Merger is in the best
interests of the Atom Shareholders and is on terms that are fair to such
shareholders, and has recommended the Merger to the Atom Shareholders, and (c)
submitted this Agreement, the Merger and the transactions and agreements
contemplated by this Agreement to the vote and approval of Atom Shareholders.

agreeing to vote for approval of this Agreement, the Merger, the Restated
Articles of Incorporation and the other transactions contemplated by this
Agreement.

        3.24 No Existing Discussions. Neither Atom nor any director, officer,
employee or agent of Atom or, to Atom's knowledge, any Atom Shareholder, is
engaged, directly or indirectly, in any discussions or negotiations with any
third party relating to any Alternative Transaction (as defined in Section 5.7).

        3.25 Disclosure. Neither this Agreement, its exhibits and schedules and
the Atom Disclosure Letter, nor any Atom Ancillary Agreements delivered by Atom
to Shockwave under



                                       31
   33
this Agreement, taken together, contains any untrue statement of a material fact
or omits to state any material fact necessary in order to make the statements
contained herein and therein, in light of the circumstances under which such
statements were made, not misleading.

        3.26 Tax Matters. Atom has not taken or agreed to take any action, nor
does Atom have knowledge of any fact or circumstance that would prevent the
Merger from qualifying as a reorganization within the meaning of Section 368(a)
of the Code.

                                       34

Shareholders with respect to the Shockwave Common Stock and Shockwave Preferred
Stock and the rights of holders of options and warrants to purchase Shockwave
Common Stock.

        4.7 Taxes. Shockwave has timely filed all federal, state, local and
foreign tax and information returns required to be filed by it, has timely paid
all taxes required to be paid by it for which payment is due, has established an
adequate accrual or reserve for the payment of all taxes payable in respect of
the periods or portions thereof prior to the Closing Date subsequent to the
periods covered by its most recent applicable tax returns (which accrual or
reserve as of the Shockwave Balance Sheet Date (as defined in Section 4.8) is
fully reflected on the Shockwave Balance Sheet and in any more recent balance
sheet of Shockwave provided by Shockwave to Shockwave on or before the Agreement
Date), has made all necessary estimated tax payments, and has no liability for
taxes in excess of the amount so paid or accruals or reserves so established.
All such returns and reports are true, correct and complete, and Shockwave has
provided Shockwave with true and correct copies of such returns and reports.
Shockwave is not delinquent in the payment of any tax or in the filing of any
tax returns, and no deficiencies for any tax have been threatened, claimed,
proposed or assessed against Shockwave or any of the officers, employees or
agents of Shockwave in their capacity as such. Shockwave has not received any
notification from the Internal Revenue Service or any other taxing authority
regarding any material issues that: (i) are currently pending before the
Internal Revenue Service or any other taxing authority (including but not
limited to any sales or use tax authority) regarding Shockwave, or (ii) have
been raised by the Internal Revenue Service or other taxing authority and not
yet finally resolved. No tax return of Shockwave is under audit by the Internal
Revenue Service or any state or local taxing agency or authority and any such
past audits (if any) have been completed and fully resolved to the satisfaction
of the applicable tax authority conducting such audit and all taxes determined
by such audit to be due from Shockwave have been paid in full to the applicable
taxing authorities. No tax liens are currently in effect against any assets of
Shockwave other than liens which arise by operation of law for taxes not yet due
and payable. There is not in effect any waiver by Shockwave of any statute of
limitations with respect to any taxes; and Shockwave has not consented to extend
the due date for which any tax may be assessed or collected by any taxing
authority. Shockwave is not a "personal holding company" within the meaning of
the Code. Shockwave has withheld with respect to each of its employees and
independent contractors all taxes, including but not limited to federal and
state income taxes, FICA, Medicare, FUTA and other taxes, required to be
withheld, and paid such withheld amounts to the appropriate tax authority within
the time prescribed by law. Since its inception, Shockwave has not been a
"United States real property holding corporation," as defined in Section
897(c)(2) of the Code, and in Section 1.897-2(b) of the Regulations, and
Shockwave has filed, or at the Effective Time will file, with the Internal
Revenue Service all statements, if any, which are required under Section
1.897-2(h) of the Regulations. Shockwave has not been distributed in a
transaction qualifying under Section 355 of the Code within the last two years,
nor has Shockwave distributed any corporation in a transaction qualifying under
Section 355 of the Code within the last two years. Shockwave has not elected
pursuant to the



                                       35
   37
Code to be treated as an "S" corporation or a collapsible corporation pursuant
to Section 1362(a) or Section 341(f) of the Code. Shockwave will not, as a
result of any action taken prior to the Effective Time, have any adjustment
under Section 481 of the Code for periods after the Effective Time.

        4.8 Shockwave Financial Statements. Attached as Schedule 4.8 to the
Shockwave Disclosure Letter are Shockwave's audited balance sheet as of March
31, 2000, its unaudited consolidated statements of operations, statements of
cash flows and statements of changes in shareholders' equity for the year ended
March 31, 2000, its unaudited balance sheet of Shockwave as of October 31, 2000,
and its unaudited consolidated statements of operations, statements of cash
flows and statements of changes in shareholders' equity for the seven-months
ended October 31, 2000 (all such financial statements of Shockwave and any notes
thereto are hereinafter collectively referred to as the "SHOCKWAVE FINANCIAL
STATEMENTS"). The Shockwave Financial Statements: (a) are derived from and are
in accordance with the books and records of Shockwave, (b) fairly present the
financial condition of Shockwave at the dates therein indicated and the results
of operations for the periods therein specified, and (c) have been prepared in
accordance with United States GAAP applied on a basis consistent with prior
periods except for any absence of notes with respect to the unaudited Shockwave
Financial Statements. Shockwave has no material debt, liability or obligation of
any nature, whether accrued, absolute, contingent or otherwise, and whether due
or to become due, except for (a) those shown on Shockwave's unaudited balance
sheet as of October 31, 2000 included in the Shockwave Financial Statements (the
"SHOCKWAVE BALANCE SHEET"), and (b) those that may have been incurred after
October 31, 2000 (the "SHOCKWAVE BALANCE SHEET DATE") in the ordinary course of
Shockwave's business consistent with its past practices, and that are not
material in amount, either individually or collectively. All reserves
established by Shockwave that are set forth in or reflected in the Shockwave
Balance Sheet are adequate. At the Shockwave Balance Sheet Date, there were no
material loss contingencies (as such term is used in Statement of Financial
Accounting Standards No. 5 issued by the Financial Accounting Standards Board in
March 1975) which are not adequately provided for in the Shockwave Balance Sheet
as required by said Statement No. 5. The Shockwave Financial Statements comply
in all material respects with the American Institute of Certified Public
Accountants' Statement of Position 97-2. For purposes of this Section 4.8 only,
references to "material" means the amount of $200,000 or more.

        4.9 Absence of Certain Changes. Since the Shockwave Balance Sheet Date,
there has not been with respect to Shockwave any:

               (a) Material Adverse Change;

               (b) amendment or change in the Certificate of Incorporation or
Bylaws or other charter documents;

               (c) damage, destruction or loss of any property or asset, whether
or not covered by insurance, having (or likely with the passage of time to have)
a Material Adverse Effect on Shockwave;



                                       36
   38
               (d) declaration, setting aside or payment of any dividend on, or
the making of any other distribution in respect of, the capital stock of
Shockwave, or any split, combination or recapitalization of the capital stock of
Shockwave or any direct or indirect redemption, purchase or other acquisition of
any capital stock of Shockwave or any change in any rights, preferences,
privileges or restrictions of any outstanding security of Shockwave;

               (e) grant or issuance of any options, warrants or other rights to
acquire from Shockwave, directly or indirectly, except as described in Section

as presently proposed to be conducted by Shockwave (such Intellectual Property
being hereinafter collectively referred to as the "SHOCKWAVE IP RIGHTS"), and
such rights to use, possess, sell, license, copy, distribute, market, advertise
and/or dispose of are sufficient for such conduct of such business.

               (b) Neither the execution, delivery and performance of this
Agreement nor the consummation of the Merger and the other transactions
contemplated by this Agreement will: (a) constitute a material breach of or
default under any instrument, contract, license or other agreement governing any

IP RIGHTS AGREEMENTS"); (b) cause the forfeiture or termination of, or give rise
to a right of forfeiture or termination of, any Shockwave IP Right; or (c)

is there any basis for any such claim, nor has Shockwave received any notice
asserting that any Shockwave IP Right or the proposed use, sale, license or

consultant or independent contractor of Shockwave: (i) is in material violation
of any term or covenant of any



                                       38
   40
employment contract, patent disclosure agreement, invention assignment
agreement, non-disclosure agreement, noncompetition agreement or any other

which is Intellectual Property, by virtue of such employee's, consultant's, or
independent contractor's being employed by, or performing services for,
Shockwave or using trade secrets or proprietary information of others without

copyrightable, patentable or otherwise proprietary work or any Intellectual
Property related thereto. To Shockwave's knowledge, the employment of any

such agreements have been delivered to Shockwave's counsel.

sold, licensed, leased or delivered by Shockwave to customers and all services
provided by Shockwave to customers on or prior to the Closing Date conform in
all material respects to applicable contractual commitments, express and implied
warranties, product specifications and product documentation and to any
representations provided to customers and Shockwave has no material liability
(and, to Shockwave's knowledge, there is no basis for any present or future
action, suit, proceeding, hearing, investigation, charge, complaint, claim or
demand against Shockwave giving rise to any liability relating to the foregoing
contracts that could have a Material Adverse Effect on Shockwave) for
replacement or repair thereof or other damages in connection therewith in excess
of any reserves therefor reflected on the Shockwave Balance Sheet.

produce and display the short films, animations and other digital media on its
website or available by Shockwave for syndication. Except pursuant to a license,

such Governmental Permits are in full force and effect. Shockwave has not
received any notice or other communication from any Governmental Authority
regarding (i) any actual or possible violation of law or any Governmental Permit
or any failure to comply with any term or requirement of any Governmental
Permit, or (ii) any actual or possible revocation, withdrawal, suspension,
cancellation, termination or modification of any Governmental Permit.

Incorporation and Bylaws as currently in effect; and (b) Shockwave's minute book

material respects true, complete and correct, (ii) have been maintained in
accordance with good business practices on a basis consistent with prior years,
(iii) are stated in reasonable detail and accurately and fairly reflect the
transactions and dispositions of the assets of Shockwave, and (iv) accurately

               (b) Shockwave has devised and maintains a system of internal
accounting controls sufficient to provide reasonable assurances that: (i)
transactions are executed in accordance with management's general or specific
authorization; (ii) transactions are recorded as necessary (A) to permit
preparation of financial statements in conformity with generally accepted
accounting principles or any other criteria applicable to such statements, and
(B) to maintain accountability for assets; and (iii) the amount recorded for

assets at reasonable intervals and appropriate action is taken with respect to
any differences.

        4.15 Environmental Matters. Shockwave is in material compliance with all
applicable Environmental Laws, which compliance includes the possession by
Shockwave of all permits and other governmental authorizations required under
applicable Environmental Laws, and compliance with the terms and conditions
thereof. Shockwave has not received any notice or other communication (in
writing or otherwise), whether from a governmental body, citizens



                                       40
   42
groups, employee or otherwise, that alleges that Shockwave is not in compliance
with any Environmental Law, and to Shockwave's knowledge, there are no
circumstances that may prevent or interfere with the compliance by Shockwave
with any current Environmental Law in the future. To Shockwave's knowledge, no
current or prior owner of any property leased or possessed by Shockwave has
received any notice or other communication (in writing or otherwise), whether
from a government body, citizens group, employee or otherwise, that alleges that
such current or prior owner or Shockwave is not in compliance with any
Environmental Law.

        4.16 Accounts Receivable. The receivables shown on the Shockwave Balance
Sheet on the Shockwave Balance Sheet Date arose in the ordinary course of
business, consistent with past practice, and have been collected or are
collectible in the book amounts thereof, less an amount not in excess of the
allowance for doubtful accounts provided for in the balance sheet of Shockwave
on the Shockwave Balance Sheet Date. Allowances for doubtful accounts and
warranty returns are adequate and have been prepared in accordance with GAAP
consistently applied and in accordance with the past practices of Shockwave. The
receivables of Shockwave arising after the Shockwave Balance Sheet Date and
prior to the Closing Date arose or will arise in the ordinary course of
business, consistent with past practice, and have been collected or are
collectible in the book amounts thereof, less allowances for doubtful accounts
determined in accordance with the past practices of Shockwave. To the knowledge
of Shockwave, none of its receivables is subject to any material claim of
offset, recoupment, setoff or counter-claim and it has no knowledge of any
specific facts or circumstances (whether asserted or unasserted) that could give
rise to any such claim. No material amount of receivables are contingent upon
the performance by Shockwave of any obligation or contract other than normal
warranty repair and replacement. No person has any Encumbrance on any of such
receivables and no agreement for deduction or discount has been made with
respect to any of such receivables. Schedule 4.16 sets forth an aging of
accounts receivable of Shockwave in the aggregate and by customer, and indicates
the amounts of allowances for doubtful accounts.

        4.17 Board Actions. The Board of Directors of Shockwave has unanimously

the Shockwave Disclosure Letter, nor any Shockwave Ancillary Agreements
delivered by Shockwave to Shockwave under this Agreement, taken together,
contains any untrue statement of a material fact or omits to state any material
fact necessary in order to make the statements contained herein and therein, in
light of the circumstances under which such statements were made, not

                                 CLOSING MATTERS

        7.1 The Closing. Subject to termination of this Agreement as provided in
Article 10, the closing of the transactions to consummate the Merger (the
"CLOSING") will take place at the offices of Fenwick & West LLP, 275 Battery
Street, San Francisco, Shockwave at 10:00 a.m., Pacific Time, on January 2, 2001
or, if all of the conditions to Closing set forth in Articles 8 and 9 have not
been satisfied and/or waived in accordance with this Agreement on or before
January 2, 2001, on the second business day after all such conditions have been
satisfied and/or waived in accordance with this Agreement, or on such other day
as Shockwave and Atom may mutually agree upon (the "CLOSING DATE"). Concurrently
with the Closing, the Articles of Merger will be filed with the Washington
Secretary of State and the Certificate of Merger will be filed with the Delaware
Secretary of State.

        7.2 Exchange of Certificates.

               (a) At the Effective Time, shares of Atom Common Stock and Atom
Preferred Stock that are outstanding immediately prior thereto will, by virtue
of the Merger and without further action, cease to exist, and all such shares
will be converted into the right to receive from Shockwave the number of
Shockwave Merger Shares to which such holder is entitled pursuant to Section
2.1, subject to the provisions of Section 2.1(e) regarding the elimination of
fractional Merger Shares), Section 2.1(f) (regarding Dissenting Shares) and
Section 2.5 (regarding the withholding of Escrow Shares). At the Closing, each
holder of shares of Atom Common Stock and Atom Preferred Stock that are
outstanding immediately prior thereto will surrender either (i) the
certificate(s) for such shares (each a "ATOM CERTIFICATE"), duly endorsed to
Shockwave for cancellation as of the Effective Time, or (ii) an affidavit of
lost certificate and an indemnity in form and substance reasonable satisfactory
to Shockwave (the "AFFIDAVIT"). Promptly after the Effective Time and receipt of
such Atom Certificate or Affidavit, as the case may be: (a) Shockwave or its
transfer agent will issue to each tendering holder of an Atom Certificate or an
Affidavit, certificates (a "TENDERING ATOM HOLDER") for the number of Shockwave
Merger Shares to which such holder is entitled pursuant to Section 2.1, subject
to the provisions of Section 2.1(e) (regarding the elimination of fractional
Merger Shares), Section 2.1(f) (regarding Dissenting Shares) and Section 2.5
(regarding the withholding of Escrow Shares); and (b) Shockwave or its transfer
agent will pay by check to each Tendering Atom Holder cash in the amounts
payable to such holder in accordance with the provisions of Sections 2.1(f).



                                       50
   52
               (b) No dividends or distributions payable to holders of record of
Shockwave Common Stock or Shockwave Preferred Stock after the Effective Time
will be paid to the holder of any unsurrendered Atom Certificate unless and
until the holder of such unsurrendered Atom Certificate surrenders such Atom
Certificate or an Affidavit to Shockwave as provided above. Subject to the
effect, if any, of applicable escheat and other laws, following surrender of any
Atom Certificate or Affidavit, there will be delivered to the person entitled
thereto, without interest, the amount of any dividends and distributions
theretofore paid with respect to Shockwave Common Stock so withheld as of any
date subsequent to the Effective Time and prior to such date of delivery.

               (c) After the Effective Time, there will be no further
registration of transfers on the stock transfer books of Atom or its transfer
agent of any shares of capital stock of Atom that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Atom Certificates or
an Affidavit are presented for any reason, they will be canceled and exchanged
as provided in this Section 7.2.

               (d) Until Atom Certificates or an Affidavit representing shares
of Atom Common Stock and Atom Preferred Stock that are outstanding immediately
prior to the Effective Time are surrendered pursuant to Section 7.2(a), such
Atom Certificates will be deemed, for all purposes, to evidence ownership of the
number of Shockwave Merger Shares into which such shares of Atom Common Stock
and Atom Preferred Stock will have been converted pursuant to Section 2.1,
subject to the provisions of Section 2.1(e) regarding the elimination of
fractional Merger Shares), Section 2.1(f) (regarding Dissenting Shares) and
Section 2.5 (regarding the withholding of Escrow Shares).

        7.3 Appraisal Rights. If holders of Atom Common Stock and Atom Preferred
Stock are entitled to appraisal rights pursuant to the WBCA in connection with
the Merger, any Dissenting Shares held by Atom Shareholders will not be
converted into a right to receive Shockwave Common Stock or Shockwave Preferred
Stock, but will be converted into the right to receive such consideration as may
be determined to be due with respect to such Dissenting Shares pursuant to the
WBCA. Atom will give Shockwave prompt notice (and in no event more than two
business days) of any demand received by Atom for appraisal of Atom Common Stock
and Atom Preferred Stock, and Shockwave will have the right to control all
negotiations and proceedings with respect to such demand. Atom agrees that,
except with the prior written consent of Shockwave, it will not voluntarily make
any payment with respect to, or settle or offer to settle, any such demand for
appraisal. In the event that any Atom Shareholder fails to make an effective
demand for payment or otherwise loses his status as a holder of Dissenting
Shares (a "DISSENTING SHAREHOLDER"), Shockwave will, as of the later of the
Effective Time of the Merger or ten business days from the occurrence of such
event, issue and deliver, upon surrender by such Dissenting Shareholder of its
Atom Certificate or Certificates or an Affidavit, the Shockwave Merger Shares,
without interest thereon, to which such Dissenting Shareholder would have been
entitled to under Section 2.1 (less the number of Escrow Shares to be held in
escrow with respect to such shareholder pursuant to Section 2.5).

        9.19 Conversion of Atom Notes. Each holder of an Atom Note will have
agreed in writing to convert such Atom Note into preferred stock of the
Surviving Corporation in its first preferred stock financing following the
Effective Time.

                            TERMINATION OF AGREEMENT

        10.1 Termination by Mutual Consent. This Agreement may be terminated at
any time prior to the Effective Time by the mutual written consent of Shockwave
and Atom.

        10.2 Unilateral Termination.

               (a) Either Shockwave or Atom, by giving written notice to the
other, may terminate this Agreement if a court of competent jurisdiction or
other Governmental Authority



                                       56
   58
will have issued a nonappealable final order, decree or ruling or taken any
other action, in each case having the effect of permanently restraining,
enjoining or otherwise prohibiting the Merger.

               (b) Either Shockwave or Atom, by giving written notice to the
other, may terminate this Agreement if the Merger will not have been consummated
by midnight Pacific Time on the Termination Date; provided, however, that the
right to terminate this Agreement pursuant to this Section 10.2(b) will not be
available to any party whose failure to perform in any material respect any of
its obligations or covenants under this Agreement results in the failure of any
condition set forth in Article 8 or Article 9 or if the failure of such
condition results from facts or circumstances that constitute a material breach
of a representation or warranty or covenant made under this Agreement by such
party.

               (c) Shockwave may terminate this Agreement at any time prior to
the Effective Time upon a breach of any representation, warranty, covenant or
agreement on the part of Atom set forth in this Agreement, or if any
representation or warranty of Atom will have become untrue, in either case such
that the conditions set forth in Section 9.1 or Section 9.2 would not be
satisfied as of the time of such breach or as of the time such representation or
warranty shall have become untrue, provided that if such inaccuracy in Atom's
representations and warranties or breach by Atom is curable by Atom through the
exercise of its commercially reasonable efforts, then Shockwave may not
terminate this Agreement under this Section 10.2(c) for ten days after delivery
of written notice from Shockwave to Atom of such breach, provided Atom continues
to exercise commercially reasonable efforts to cure such breach (it being
understood that Shockwave may not terminate this Agreement pursuant to this
Section 10.2(c) if such breach by Atom is cured during such ten-day period, or
if Shockwave shall have materially breached this Agreement).

               (d) Atom may terminate this Agreement at any time prior to the
Effective Time upon a breach of any representation, warranty, covenant or
agreement on the part of Shockwave set forth in this Agreement, or if any
representation or warranty of Shockwave will have become untrue, in either case
such that the conditions set forth in Section 8.1 or Section 8.2 would not be
satisfied as of the time of such breach or as of the time such representation or
warranty shall have become untrue, provided that if such inaccuracy in
Shockwave's representations and warranties or breach by Shockwave is curable by
Shockwave through the exercise of its commercially reasonable efforts, then Atom
may not terminate this Agreement under this Section 10.2(d) for ten days after
delivery of written notice from Atom to Shockwave of such breach, provided
Shockwave continues to exercise commercially reasonable efforts to cure such
breach (it being understood that Atom may not terminate this Agreement pursuant
to this Section 10.2(d) if such breach by Shockwave is cured during such ten-day
period, or if Atom shall have materially breached this Agreement).

               (e) No Liability for Termination. Termination of this Agreement
by a party (the "TERMINATING PARTY") in accordance with the provisions of this
Article 10 will not give rise to any obligation or liability on the part of the
Terminating Party on account of such termination; provided, however, that
nothing herein will relieve a party from liability for a willful breach of



                                       57
   59
this Agreement. The provisions of this Article 10 and Article 12 will survive
any termination of this Agreement.

                                   ARTICLE 11
                  SURVIVAL OF REPRESENTATIONS, INDEMNIFICATION
                       AND REMEDIES; CONTINUING COVENANTS

        11.1 Survival of Representations. All representations, warranties and
covenants of the parties contained in this Agreement will remain operative and
in full force and effect, regardless of any investigation made by or on behalf
of any of the parties to this Agreement, until that date (the "RELEASE DATE")
which is the earlier of (a) the termination of this Agreement in accordance with
its terms or (b) the first anniversary of the Effective Time; provided, however,
that notwithstanding the foregoing, either party may seek recovery of Damages
(as defined in Section 11.2(a) relating to Special Damages (as defined in
Section 11.2(b)) at any time prior to the expiration of the applicable statute
of limitations for the claim which seeks recovery of such Special Damages.

        11.2 Agreement to Indemnify.

               (a) (i) Shockwave will indemnify and hold harmless the Atom
Shareholders (each hereinafter referred to individually as an "ATOM INDEMNIFIED
PERSON" and collectively as "ATOM INDEMNIFIED PERSONS"), and (ii) the Atom
Shareholders severally, but not jointly, on a pro rata basis based upon their
respective ownership interests in the escrowed portion of the Atom Common Stock
and Atom Preferred Stock set forth besides their names on Schedule 3.4(a)-1 to
this Agreement ("PRO RATA BASIS"), will indemnify and hold harmless, Shockwave
and its officers, directors, agents, representatives, shareholders and
employees, and each person, if any, who controls or may control Shockwave within
the meaning of the Securities Act or the Exchange Act (each hereinafter referred
to individually as a "SHOCKWAVE INDEMNIFIED PERSON" and collectively as
"SHOCKWAVE INDEMNIFIED PERSONS") from and against any and all claims, demands,
suits, actions, causes of actions, losses, costs, damages, liabilities and
expenses including reasonable attorneys' fees, other professionals' and experts'
reasonable fees and court or arbitration costs (hereinafter collectively
referred to as "DAMAGES") directly or indirectly incurred, resulting or and
arising out of any inaccuracy, misrepresentation, breach of, or default in, any
of the representations, warranties or covenants given or made by, in the case of
a Claim (as defined in Section 11.5) made by Shockwave Indemnified Persons, Atom
in this Agreement or in the Atom Disclosure Letter or in any certificate
delivered by or on behalf of Atom or an officer of Atom pursuant hereto; or, in
the case of a Claim made by the Representatives (as defined below), Shockwave in
this Agreement, the Shockwave Disclosure Letter or in any certificate delivered
by or on behalf of Shockwave or an officer of Shockwave pursuant hereto. Except
with respect to claims arising from Special Damages, which may be raised after
the Release Date, any Claim made by Shockwave or the Representatives under this
Section 11.2(a) must be raised in a writing delivered to the other party by no
later than the Release Date and, if raised by such date, such Claim will survive
the Release Date until final resolution thereof. Escrow Shares, other than
Escrow Shares having a value (calculated pursuant to Section 11.3(a)) equal to
the amount of Damages asserted in any Claim which has not been resolved pursuant
to



                                       58
   60
the terms hereof prior to the Release Date, will be released to the Atom
Shareholders on the Release Date or, in the case of any such withheld shares,
upon the resolution of such Claim(s).

               (b) (i) Shockwave will indemnify and hold harmless Atom
Indemnified Persons from and against Damages incurred or suffered by any such
persons or arising from, by reason of or in connection with any fraudulent
conduct or fraudulent misrepresentation on the part of Shockwave or any officer,
director, employee or agent of Shockwave, and (ii) the Atom Shareholders will
severally, but not jointly, on a Pro Rata Basis, indemnify and hold harmless
Shockwave Indemnified Persons from and against Damages incurred or suffered by
any such persons or arising from, by reason of or in connection with (A) any
fraudulent conduct or fraudulent misrepresentation on the part of Atom or any
officer, director, employee or agent of Atom, or (B) any inaccuracy,
misrepresentation, breach of or default in, of the representations and
warranties of Atom set forth in Section 3.4 (Capitalization) or Section 3.7
(Taxes) (collectively, "SPECIAL DAMAGES").

        11.3 Limitation.

               (a) Cap On Indemnity Obligation of the Atom Shareholders. Except
with respect to claims for indemnification for Special Damages, in no event will
the total of the Claims for Damages against any Atom Shareholder exceed the
value of such Atom Shareholder's pro rata portion of the escrowed Shockwave
Merger Shares received by such Atom Shareholder in the Merger. The value of each
share of Shockwave Common Stock, Shockwave Series C-1 Preferred Stock, Shockwave
Series C-2 Preferred Stock or Shockwave Series C-3 Preferred Stock, for such
purposes of satisfying claims for Damages, will be deemed to equal the fair
market value on the Closing Date per share of Shockwave Common Stock, Shockwave
Series C-1 Preferred Stock, Shockwave Series C-2 Preferred Stock or Shockwave
Series C-3 Preferred Stock as determined in good faith by the board of directors
of Shockwave. Except with respect to Special Damages, each Atom Shareholder
agrees that Claims against such shareholder under this Article 11 shall be
satisfied by the forfeiture of such shareholder's Escrow Shares (including
fractions of a share thereof) as provided for in this Article 11 and that no
Shockwave Indemnified Person will have any obligation to exercise its remedies
against any other assets of such shareholder prior to exercising them against
such Escrow Shares. In the event of a Capital Change after the Effective Time,
the fair market value of the Escrow Shares will, for purposes of this Section
11.3, be proportionally and equitably adjusted. In no event will the total of
the Claims for Damages against any Atom Shareholder for Special Damages exceed
50% of the fair market value on the Closing Date of the Merger Shares issued to
such Atom Shareholder.

               (b) Cap On Indemnity Obligation of Shockwave. In no event will
the total of the Claims for Damages against Shockwave exceed the fair market
value on the Closing Date of the Escrow Shares (the "SHOCKWAVE INDEMNIFICATION
LIMIT"). Shockwave will satisfy any Claim for Damages, at its option, in either
cash or shares of Shockwave Common Stock and Shockwave Series C Preferred Stock.
If Shockwave elects to issue shares of Shockwave Common Stock and Shockwave
Series C Preferred Stock to satisfy any Claim, such shares will have an
aggregate fair market value equal to such Claim, and such shares of Shockwave
Common Stock and Shockwave Series C Preferred Stock will be allocated
proportionally to each



                                       59
   61
Atom Shareholder according to such shareholder's ownership of shares of Atom
Common Stock and Atom Preferred Stock immediately prior to the Effective Time.
The value of each share of Shockwave Common Stock, Shockwave Series C-1
Preferred Stock, Shockwave Series C-2 Preferred Stock or Shockwave Series C-3
Preferred Stock, for such purposes of satisfying claims for Damages, will be
deemed to equal the fair market value on the Closing Date per share of Shockwave
Common Stock, Shockwave Series C-1 Preferred Stock, Shockwave Series C-2
Preferred Stock or Shockwave Series C-3 Preferred Stock as determined in good
faith by the board of directors of Shockwave.

               (c) Basket. The indemnification provided for in Section 11.2(a)
will not apply unless and until the aggregate Damages for which one or more
Shockwave Indemnified Persons or Atom Indemnified Persons, as the case may be,
seeks or has sought indemnification hereunder exceeds a cumulative aggregate of
$100,000 (the "BASKET"), in which event Atom Shareholders or Shockwave, as the
case may be, will, subject to the limitations Section 11.3(a) and (b), be liable
to indemnify the Shockwave Indemnified Persons or the Atom Indemnified Persons,
as the case may be, for all Damages; provided, however, that the Basket and the
foregoing provisions of this sentence will not apply to any Claim for fraudulent
conduct, fraudulent misrepresentation or other willful misconduct on the part of
Shockwave or any officer, director, employee or agent of Shockwave, or Atom, an
Atom Shareholder or any officer, director, employee or agent of Atom.

               (d) Exclusive Contractual Remedy and Limitations. Shockwave, the
Atom Shareholders and Atom each acknowledge that resort to this Article 11 shall
be the exclusive contractual remedy of Shockwave, the Shockwave Indemnified
Persons, Atom and the Atom Indemnified Persons for any Claim for Damages.
Shockwave, the Atom Shareholders and Atom each further acknowledge that resort
to the Escrow Fund shall be the exclusive contractual remedy of Shockwave and
the Shockwave Indemnified Persons for any Claim for Damages by Shockwave, and
the Shockwave Indemnification Limit shall be the exclusive contractual remedy of
Atom and the Atom Indemnified Persons for any Claim for Damages by the
Representatives. The maximum liability of any Atom Shareholder for any breach of
a representation, warranty or covenant of Atom will be limited to the Escrow
Shares in which such holder has an interest; provided, however, that the maximum
liability of any Atom Shareholder for Special Damages will be limited to 50% of
the fair market value on the Closing Date of the Merger Shares issued to such
Atom Shareholder. The maximum liability of Shockwave for Special Damages will be
limited to 50% of the Shockwave Indemnification Limit.

        11.4 Appointment of Representatives. Robert Egan and Thomas Heogh will
act as representatives (the "REPRESENTATIVES") of the Atom Shareholders and as
the attorneys-in-fact and agents for and on behalf of each Atom Shareholder with
respect to Claims under Article 11. Any action taken or decisions made by
Messrs. Egan and Heogh as Representatives will be taken or made jointly. The
Representatives will take any and all actions and the make any decisions
required or permitted to be taken by the Representatives under this Agreement,
including the exercise of the power to: (a) authorize the release or delivery to
Shockwave of Escrow Shares and any other assets deposited in escrow pursuant to
the terms of Section 2.5 and Article 11 (including any shares of Shockwave
capital stock or other securities into which Shockwave Common Stock or Shockwave
Preferred Stock is converted or exchanged or which is received in



                                       60
   62
respect of such Escrow Shares or other capital stock and securities) in
satisfaction of Claims by any Shockwave Indemnified Person pursuant to Article
11; (b) agree to, negotiate, enter into settlements and compromises of, demand
arbitration of, and comply with orders of courts and awards of arbitrators with
respect to, such Claims; (c) arbitrate, resolve, settle or compromise any Claim
made pursuant to Article 11; and (d) take all actions necessary in the judgment
of the Representatives for the accomplishment of the foregoing. The
Representatives will have authority and power to act on behalf of each Atom
Shareholder with respect to the disposition, settlement or other handling of all
Claims under Article 11 and all rights or obligations arising under Article 11.
The Atom Shareholders will be bound by all actions taken and documents executed
by the Representatives in connection with Article 11, and Shockwave will be
entitled to rely on any action or decision of the Representatives. In performing
the functions specified in this Agreement, the Representatives will not be
liable to any Atom Shareholder in the absence of gross negligence or willful
misconduct on the part of the Representatives. The Atom Shareholders will
severally, but not jointly, on a Pro Rata Basis, indemnify the Representatives
and hold him harmless against any loss, liability or expense incurred without
gross negligence or willful misconduct on the part of the Representatives and
arising out of or in connection with the acceptance or administration of his
duties hereunder; provided that in no event will such indemnification against
any Atom Shareholder exceed the value of such Atom Shareholder's pro rata
portion of the escrowed Shockwave Merger Shares received by such Atom
Shareholder in the Merger. Any out-of-pocket costs and expenses reasonably
incurred by the Representatives in connection with actions taken by the
Representatives pursuant to the terms of Article 11 (including the hiring of
legal counsel and the incurring of legal fees and costs) will be paid by the
Atom Shareholders to the Representatives on a Pro Rata Basis.

        11.5 Notice of Claim. As used herein, the term "CLAIM" means a claim for
indemnification of any Shockwave Indemnified Person or Atom Indemnified Person
for Damages under Article 11. Shockwave (and only Shockwave) may give notice of
a Claim under this Agreement whether for its own Damages or for Damages incurred
by any other Shockwave Indemnified Person, and the Representatives (and only the
Representatives) may give notice of a Claim under this Agreement for Damages
incurred by any Atom Indemnified Person. In the case of a Claim by a Shockwave
Indemnified Person, Shockwave will give written notice of the Claim executed by
an officer of Shockwave to the Representatives and, in the case of a Claim by an
Atom Indemnified Person, the Representatives will give written notice of the
Claim to Shockwave (a "NOTICE OF CLAIM"), in each case promptly after Shockwave
or the Representatives, as the case may be, becomes aware of the existence of
any potential Claim by a Shockwave Indemnified Person against the Atom
Shareholders or an Atom Shareholder or by an Atom Indemnified Person against
Shockwave under Article 11, but in any event before the Release Date arising
from or relating to:

               (a) (i) in the case of a Claim made by Shockwave, any inaccuracy,
misrepresentation, breach of, or default in, any of the representations,
warranties or covenants given or made by Atom in this Agreement or in the Atom
Disclosure Letter or in any certificate delivered by Atom or an officer of Atom
pursuant hereto; or (ii) in the case of a Claim made by the Representatives, any
inaccuracy, misrepresentation, breach of, or default in, any of the
representations, warranties or covenants given or made by Shockwave in this
Agreement or in



                                       61
   63
the Shockwave Disclosure Letter or in any certificate delivered by Shockwave or
an officer of Shockwave pursuant hereto; or

               (b) only in the case of a Claim made by Shockwave, the assertion,
whether orally or in writing, against Shockwave or against any other Shockwave
Indemnified Person of a claim, demand, suit, action, arbitration, investigation,
inquiry or proceeding brought by a third party against such Shockwave
Indemnified Person that is based upon, or includes assertions that would, if
true, constitute (in each such case, a "THIRD-PARTY CLAIM") any inaccuracy,
misrepresentation, breach of, or default in, any of the representations,
warranties or covenants given or made by Atom in this Agreement or in the Atom
Disclosure Letter or in any certificate delivered by or on behalf of Atom or an
officer of Atom pursuant hereto (if such inaccuracy, misrepresentation, breach
or default existed at the Closing Date).

        Until the Release Date, no delay on the part of Shockwave in giving the
Representatives, or on the part of the Representatives in giving Shockwave, a
Notice of Claim will relieve the Representatives or any Atom Shareholder (in the
case of a Claim made by Shockwave) or Shockwave (in the case of a Claim made by
the Representatives) from any of its obligations under Article 11 unless (and
then only to the extent) that the Representatives or the Atom Shareholders (in
the case of a Claim made by Shockwave) or Shockwave (in the case of a Claim made
by the Representatives) are materially prejudiced thereby.

        11.6 Defense of Third-Party Claims.

               (a) Shockwave will defend any Third-Party Claim, and the costs
and expenses incurred by Shockwave in connection with such defense (including
but not limited to reasonable attorneys' fees, other professionals' and experts'
fees and court or arbitration costs) will be included in the Damages for which
Shockwave may seek indemnity pursuant to a Claim made by any Shockwave
Indemnified Person hereunder.

               (b) The Representatives will have the right to receive copies of
all pleadings, notices and communications with respect to the Third-Party Claim
to the extent that receipt of such documents by the Representatives does not
affect any privilege relating to the Indemnified Person, and may participate in
settlement negotiations with respect to the Third-Party Claim. No Shockwave
Indemnified Person will enter into any settlement of a Third-Party Claim without
the prior written consent of the Representatives (which consent will not be
unreasonably withheld), provided, that if the Representatives will have
consented in writing to any such settlement, then the Representatives will have
no power or authority to object to any Claim by any Shockwave Indemnified Person
under Section 11.2 for the amount of such settlement; and the Atom Shareholders
will remain responsible to indemnify the Shockwave Indemnified Persons for all
Damages they may incur arising out of, resulting from or caused by the
Third-Party Claim to the fullest extent provided in Article 11.

        11.7 Contents of Notice of Claim. Each Notice of Claim by Shockwave or
the Representatives given pursuant to Section 11.5 will contain the following
information:



                                       62
   64
               (a) such party's good faith estimate of the reasonably
foreseeable maximum amount of the alleged Damages arising from such Claim (which
amount, in the case of Third-Party Claims, may be the amount of damages claimed
by the third party in an action brought against any Shockwave Indemnified Person
based on alleged facts, which if true, would give rise to liability for Damages
to such Shockwave Indemnified Person under Article 11); and

               (b) a brief description, in reasonable detail (to the extent
reasonably available to such party), of the facts, circumstances or events
giving rise to the alleged Damages based on such party's good faith belief
thereof, including the identity and address of any third-party claimant (to the
extent reasonably available to such party) and copies of any formal demand or
complaint.

        11.8 Resolution of Notice of Claim. Any Notice of Claim received by the
Notified Party pursuant to Sections 11.5 and 11.7 will be resolved as follows:

               (a) Uncontested Claims. In the event that, within thirty calendar
days after a Notice of Claim is received by the Representatives or Shockwave, as
the case may be (the "NOTIFIED PARTY"), pursuant to Sections 11.5 and 11.7, the
Notified Party does not contest such Notice of Claim in writing to Shockwave or
the Representatives, as the case may be (the "NOTIFYING PARTY") as provided in
Section 11.8(b) (an "UNCONTESTED CLAIM"), the Notified Party will be
conclusively deemed to have consented to the recovery by the Notifying Party of
the full amount of Damages specified in the Notice of Claim in accordance with
Article 11, including, in the case of a Claim against the Atom Shareholders, the
forfeiture of shares of Shockwave Common Stock, Shockwave Preferred Stock and
any other assets deposited in escrow pursuant to the terms of Section 2.5 and
Article 11 (including any shares of Shockwave capital stock or other securities
into which Shockwave Common Stock or Shockwave Preferred Stock is converted or
exchanged or which is received in respect of such shares of Shockwave Common
Stock, Shockwave Preferred Stock or other capital stock and securities), in
accordance with Section 11.3(a) and, without further notice, to have stipulated
to the entry of a final judgment for damages against, as the case may be,
Shockwave or the Atom Shareholders for such amount in the Superior Court for the
County of San Francisco, the United States District Court for the Northern
District of California or any other court having jurisdiction over the matter
where venue is proper.

               (b) Contested Claims. In the event that the Notified Party gives
the Notifying Party written notice contesting all or any portion of a Notice of
Claim (a "CONTESTED CLAIM") within the thirty day period specified in Section
11.8(a), then: (i) such Contested Claim will be resolved by either (A) a written
settlement agreement executed by the Notified Party and the Notifying Party or
(B) in the absence of such a written settlement agreement, by binding
arbitration between the Notified Party and the Notifying Party in accordance
with the terms and provisions of Section 11.8(c).

               (c) Arbitration of Contested Claims. Shockwave and Atom agree
that any Contested Claim will be submitted to mandatory, final and binding
arbitration before J.A.M.S./ENDISPUTE or its successor ("J.A.M.S."), pursuant to
the United States Arbitration




                                       63
   65
Act, 9 U.S.C., Section 1 et seq. and that any such arbitration will be conducted
in San Francisco County, California. Either Shockwave or the Representatives may
commence the arbitration process called for by this Agreement by filing a
written demand for arbitration with J.A.M.S. and giving a copy of such demand to
each of the other party to this Agreement. The arbitration will be conducted in
accordance with the provisions of J.A.M.S' Streamlined Arbitration Rules and
Procedures in effect at the time of filing of the demand for arbitration,
subject to the provisions of Section 11.8(c). The parties will cooperate with
J.A.M.S. and with each other in promptly selecting an arbitrator from J.A.M.S.'
panel of neutrals, and in scheduling the arbitration proceedings in order to
fulfill the provisions, purposes and intent of this Agreement. The parties
covenant that they will participate in the arbitration in good faith, and that
they will share in its costs in accordance with subparagraph (i) below. The
provisions of this Section 11.8(c) may be enforced by any court of competent
jurisdiction, and the party seeking enforcement will be entitled to an award of
all costs, fees and expenses, including attorneys' fees, to be paid by the party
against whom enforcement is ordered. Subject to the provisions of subparagraph
(vii) below, judgment upon the award rendered by the arbitrator may be entered
in any court having competent jurisdiction.

                      (i) Payment of Costs. The parties will bear the expense of
deposits and advances required by the arbitrator in equal proportions, but
either party may advance such amounts, subject to recovery as an addition or
offset to any award. The arbitrator will determine the party who is the
prevailing party and the party who is the non-prevailing party. The
non-prevailing party will pay all reasonable costs, fees and expenses related to
the arbitration, including reasonable fees and expenses of attorneys,
accountants and other professionals incurred by the prevailing party, the fees
of each arbitrator and the administrative fee of the arbitration proceedings. If
such an award would result in manifest injustice, however, the arbitrator may
apportion such costs, fees and expenses between the parties in such a manner as
the arbitrator deems just and equitable.

                      (ii) Burden of Proof. Except as may be otherwise expressly
provided herein, for any Contested Claim submitted to arbitration, the burden of
proof will be as it would be if the claim were litigated in a judicial
proceeding governed by California law exclusively.

                      (iii) Award. Upon the conclusion of any arbitration
proceedings hereunder, the arbitrator will render findings of fact and
conclusions of law and a final written arbitration award setting forth the basis
and reasons for any decision reached (the "FINAL AWARD") and will deliver such
documents to the Representatives and Shockwave, together with a signed copy of
the Final Award. Subject to the provisions of subparagraph (vii) below, the
Final Award will constitute a conclusive determination of all issues in
question, binding upon the Atom Shareholders, the Representatives and Shockwave,
and will include an affirmative statement to such effect. To the extent that the
Final Award determines that a Shockwave Indemnified Person or an Atom
Indemnified Person has actually incurred Damages in connection with the
Contested Claim through the date of the Final Award ("INCURRED DAMAGES"), the
Final Award will set forth and award to the Shockwave Indemnified Persons or the
Atom Indemnified Persons, as the case may be, the amount of such Incurred
Damages. In addition, the Final Award will set forth and award to the Shockwave
Indemnified Persons or the Atom Indemnified



                                       64
   66
Persons, as the case may be, an additional amount of Damages equal to the
reasonably foreseeable amount of alleged Damages that the arbitrator determines
(based on the evidence submitted by the parties in the arbitration) are
reasonably likely to be incurred by such persons as a result of the facts giving
rise to the Contested Claim ("ESTIMATED DAMAGES"), which amount of Estimated
Damages may include the amount of damages claimed by a third party in an action
brought against any Indemnified Person based on alleged facts which, if true,
would give rise to Damages. Awards of Damages will be subject to the provisions
regarding the "Basket" (as defined in Section 11.3); provided, however, that
awards of Damages arising out of fraudulent conduct, fraudulent
misrepresentation or other willful misconduct on the part of Shockwave or any
officer, director, employee or agent of Shockwave; or Atom or any officer,
director, employee or agent of Atom or any subsidiary of Atom will not be
subject to such provisions regarding the "Basket."

                      (iv) Timing. The Representatives, Shockwave and the
arbitrator will conclude each arbitration pursuant to this Section 11.8 as
promptly as possible for the Contested Claim being arbitrated.

                      (v) Terms of Arbitration. The arbitrator chosen in
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions or the provisions of
this Agreement.

                      (vi) Exclusive Remedy. Following the Effective Time,
except as specifically otherwise provided in this Agreement, arbitration
conducted in accordance with this Agreement will be the sole and exclusive
remedy of the parties for any Claim made pursuant to Article 11.

                      (vii) Treatment of Damages. Upon issuance and delivery of
the Final Award as provided in subparagraph (iii) above, the Shockwave
Indemnified Persons or Atom Indemnified Persons, as the case may be, will
immediately be entitled to recover (A) the amount of any Incurred Damages
determined and awarded under such Final Award and (B) the amount of Estimated
Damages determined and awarded under such Final Award and such Incurred Damages
and such Estimated Damages will be deemed to be owed to the Shockwave
Indemnified Persons or Atom Indemnified Persons, as the case may be, for
purposes of this Agreement. Both Incurred Damages and Estimated Damages owed to
Shockwave Indemnified Persons or Atom Indemnified Persons, as the case may be,
are deemed to be Damages for purposes of this Agreement.

        11.9 Distribution Upon Termination of Escrow Period. As soon as
reasonably practicably following the Release Date, Shockwave will deliver to the
Atom Shareholders all of the Escrow Shares in excess of any amount of Escrow
Shares necessary to satisfy any unsatisfied or disputed claims for Damages
specified in any Notice of Claim delivered to the Representatives before the
Release Date. As soon as all such claims have been resolved, Shockwave will
deliver to the Atom Shareholders all remaining Escrow Shares not required to
satisfy such claims.

                                  MISCELLANEOUS

        12.1 Governing Law. The internal laws of the State of California,
irrespective of its choice of law principles, will govern the validity of this
Agreement, the construction of its terms, and the interpretation and enforcement
of the rights and duties of the parties hereto; provided however, that issues
involving the consummation and effects of the Merger will be governed by the
laws of the States of Delaware and Washington.

        12.2 Assignment; Binding Upon Successors and Assigns. Except as set
forth in Section 12.12, neither party hereto may assign any of its rights or
obligations hereunder without the prior written consent of the other party
hereto. This Agreement will be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns. Any
assignment in violation of this provision will be void.

        12.3 Severability. If any provision of this Agreement, or the
application thereof, will for any reason and to any extent be invalid or
unenforceable, then the remainder of this Agreement and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of the void or unenforceable provision.

        12.4 Counterparts. This Agreement may be executed in any number of
counterparts, each of which will be an original as regards any party whose
signature appears thereon and all of which together will constitute one and the
same instrument. This Agreement will become binding when one or more
counterparts hereof, individually or taken together, will bear the signatures of
all parties reflected hereon as signatories.

        12.5 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party hereunder will be deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such party, and the exercise of any one remedy will not preclude the exercise
of any other. The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties will be entitled to seek an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any court of the United States or any state
having jurisdiction.

        12.6 Amendment and Waivers. Any term or provision of this Agreement may
be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default or any succeeding
breach or default. This Agreement may be amended by the parties hereto as
provided in this Section at any time before or after approval of this Agreement
by the Atom Shareholders



                                       66
   68
or the Shockwave Shareholders, but, after such approval, no amendment will be
made which by applicable law requires the further approval of the Atom
Shareholders or the Shockwave Shareholders without obtaining such further
approval. At any time prior to the Effective Time, each of Atom and Shockwave,
by action taken by its Board of Directors, may, to the extent legally allowed,
(a) extend the time for the performance of any of the obligations or other acts
of the other; (b) waive any inaccuracies in the representations and warranties
made to it contained herein or in any document delivered pursuant hereto; and
(c) waive compliance with any of the agreements or conditions for its benefit
contained herein. No such waiver or extension will be effective unless signed in
writing by the party against whom such waiver or extension is asserted. The
failure of any party to enforce any of the provisions hereof will not be
construed to be a waiver of the right of such party thereafter to enforce such
provisions.

        12.7 Expenses. Each party will bear its respective legal, auditors',
investment bankers' and financial advisors' fees and other expenses incurred
with respect to this Agreement, the Merger and the other transactions
contemplated by this Agreement ("TRANSACTION EXPENSES"); provided, however,
that, if the Merger is successfully consummated, any Transaction Expenses of
Atom (including Transaction Expenses that are paid by Atom at or prior to the
Effective Time, but excluding fees and expenses of Morgan Stanley, which fees
and expenses will be paid by Shockwave as the Surviving Corporation following
the Merger) in excess of $350,000 will be paid by the Atom Shareholders at or
prior to the Closing; provided further that any fees and expenses of a purchaser
representative for the Atom Shareholders who are unaccredited investors will be
paid by the Atom Shareholders. If for any reason Shockwave pays any amounts in
excess of the foregoing limit, Shockwave will be entitled to be reimbursed by
the Atom Shareholders for such payment and, if not so reimbursed, Shockwave will
be entitled to treat the amount of payment as Damages recoverable under Section
11.2, without giving effect to the Basket.

        12.8 Attorneys' Fees. Should suit be brought to enforce or interpret any
part of this Agreement, the prevailing party will be entitled to recover, as an
element of the costs of suit and not as damages, reasonable attorneys' fees to
be fixed by the court (including costs, expenses and fees on any appeal). The
prevailing party will be entitled to recover its costs of suit, regardless of
whether such suit proceeds to final judgment.

        12.9 Notices. All notices and other communications required or permitted
under this Agreement will be in writing and will be either hand delivered in
person, sent by facsimile, sent by certified or registered first class mail,
postage pre-paid, or sent by nationally recognized express courier service. Such
notices and other communications will be effective upon receipt if hand
delivered or sent by facsimile, five days after mailing if sent by mail, and one

        12.10 Construction of Agreement. This Agreement has been negotiated by
the respective parties hereto and their attorneys and the language hereof will
not be construed for or against either party. A reference to a Section or an
exhibit will mean a Section in, or exhibit to, this Agreement unless otherwise
explicitly set forth. The titles and headings herein are for reference purposes
only and will not in any manner limit the construction of this Agreement which
will be considered as a whole. Unless otherwise indicated, the words "include,"
"includes" and "including" when used herein will be deemed in each case to be
followed by the words "without limitation." Each reference herein to a law,
statute, regulation, document or agreement will be deemed in each case to
include all amendments thereto.

        12.11 No Joint Venture. Nothing contained in this Agreement will be
deemed or construed as creating a joint venture or partnership between any of
the parties hereto. No party is by virtue of this Agreement authorized as an
agent, employee or legal representative of any other party. No party will have
the power to control the activities and operations of any other and their status
is, and at all times will continue to be, that of independent contractors with
respect to each other. No party will have any power or authority to bind or
commit any other party. No party will hold itself out as having any authority or
relationship in contravention of this Section.

        12.12 Further Assurances. Each party agrees to cooperate fully with the
other parties and to execute such further instruments, documents and agreements
and to give such further



                                       69
   71
written assurances as may be reasonably requested by any other party to evidence
and reflect the transactions described herein and contemplated hereby and to
carry into effect the intents and purposes of this Agreement.

        12.13 Third Party Beneficiary Rights. No provisions of this Agreement
are intended, nor will be interpreted, to provide or create any third party
beneficiary rights or any other rights of any kind in any client, customer,
affiliate, shareholder, partner or any party hereto or any other person or
entity unless specifically provided otherwise herein and, except as so provided,
all provisions hereof will be personal solely between the parties to this
Agreement; except that the provisions of Article 11 are intended to create third
party beneficiary rights for the Atom Shareholders.

        12.14 Public Announcement. Upon execution of this Agreement, Shockwave
and Atom will issue a press release approved by both parties announcing the
Merger. Thereafter, Shockwave in its discretion may issue press releases and
make other disclosures regarding the Merger. Prior to the publication of such
initial and mutually agreed press release, neither party will make any public
announcement relating to this Agreement or the other transactions contemplated
by this Agreement (except as may be required by law). Neither Shockwave nor Atom
will make any disclosures regarding this Agreement or the Merger that would
jeopardize Shockwave's ability to timely and lawfully issue the Shockwave Merger
Shares in the Merger pursuant to the exemptions described in Section 2.7.

        12.15 Atom Disclosure Letter and Shockwave Disclosure Letter. The Atom
Disclosure Letter and the Shockwave Disclosure Letter will be arranged in
separate parts corresponding to the numbered and lettered sections contained in
Articles 3 and 4, respectively, and the information disclosed in any numbered or
lettered part will be deemed to relate to and to qualify only the particular
representation or warranty set forth in the corresponding numbered or lettered
section in Articles 3 and 4, respectively, and any other representation or
warranty in such Article to which the relevance of such information is readily
apparent from the text of the information disclosed, but will not be deemed to

        12.16 Confidentiality. Atom and Shockwave each confirm that they have
entered into the Nondisclosure Agreement and that they are each bound by, and
will abide by, the provisions of such Nondisclosure Agreement (except that

party to the disclosing party or be destroyed, as provided in the Nondisclosure
Agreement.

        12.17 Entire Agreement. This Agreement, the Note Purchase Agreement and
the exhibits hereto constitute the entire understanding and agreement of the
parties hereto with respect to the subject matter hereof and supersede all prior
and contemporaneous agreements or understandings, inducements or conditions,
express or implied, written or oral, between the parties with respect hereto
other than the Nondisclosure Agreement. The express terms hereof



                                       70

                             ATOM VOTING AGREEMENT


        This ATOM VOTING AGREEMENT (this "AGREEMENT") is entered into as of
December 14, 2000 (the "AGREEMENT DATE") by and between Shockwave.com, Inc., a
Delaware corporation ("SHOCKWAVE"), and [name of shareholder] ("SHAREHOLDER").


                                    RECITALS

        A. Concurrently with the execution of this Agreement, Shockwave and Atom
Corporation, a Washington corporation ("ATOM"), are entering into an Agreement
and Plan of Reorganization dated as of December 14, 2000 (the "MERGER
AGREEMENT"), which provides (subject to the conditions set forth therein) for
the merger of Atom with and into Shockwave (the "MERGER") with Shockwave to
survive the Merger. Upon the effectiveness of the Merger, the outstanding shares
of Atom Common Stock and Atom Preferred Stock will be converted into the right
to receive Shockwave Common Stock and Shockwave Series C Preferred Stock, and
outstanding Atom Options and Atom Warrants to purchase shares of Atom Common
Stock and Atom Preferred Stock will be converted into Shockwave Options and
Shockwave Warrants, all as more particularly set forth in the Merger Agreement.
Capitalized terms used but not otherwise defined in this Agreement will have the
same meanings ascribed to such terms in the Merger Agreement.

        B. As of the Agreement Date, Shareholder owns in the aggregate
(including shares held both beneficially and of record and other shares held
either beneficially or of record) the number of shares of Atom Common Stock and
Atom Preferred Stock set forth below Shareholder's name on the signature page of
this Agreement (all such shares, together with any shares of Atom Common Stock
and Atom Preferred Stock or any other shares of capital stock of Atom that may
hereafter be acquired by Shareholder, being collectively referred to herein as
the "SUBJECT SHARES"). If, between the Agreement Date and the Expiration Date
(as defined in Section 1.1(b) below), the outstanding shares of Atom's capital
stock are changed into a different number or class of shares by reason of any
stock split, stock dividend, reverse stock split, reclassification,
recapitalization or other similar transaction, then the shares constituting the
Subject Shares shall be appropriately adjusted, and shall include any shares or
other securities of Atom issued on, or with respect to, the Subject Shares in
such a transaction.

        C. As a condition to the willingness of Shockwave to enter into the
Merger Agreement, Shockwave has required that Shareholder agree, and in order to
induce Shockwave to enter into the Merger Agreement, Shareholder has agreed, to
enter into this Agreement.

        In consideration of the facts recited above, the parties to this
Agreement, intending to be legally bound by this Agreement, now hereby agree as
follows:



   76

                                    ARTICLE 1
                           TRANSFER OF SUBJECT SHARES

        1.1 No Transfer of Voting Rights.

                (a) Shareholder covenants and agrees that, prior to the
Expiration Date, Shareholder will not deposit any of the Subject Shares into a
voting trust or grant a proxy or enter into an agreement of any kind with
respect to any of the Subject Shares, except for the Proxy called for by Section
2.2 of this Agreement and except for any other proxy granted by Shareholder to
Shockwave.

                (b) As used in this Agreement, the term "EXPIRATION DATE" shall
mean the earlier of (i) the date upon which the Merger Agreement is validly
terminated in accordance with the provisions of Article 10 of the Merger
Agreement or (ii) the Effective Time of the Merger.

        1.2 Prohibition on Disposition and Transfer. Shareholder agrees that
prior to the Expiration Date, Shareholder will not, directly or indirectly,
sell, transfer, exchange, pledge or otherwise dispose of, or in any other way
reduce Shareholder's risk of ownership or investment in, or make any offer or
agreement relating to any of the foregoing with respect to the Subject Shares,
except in connection with the Merger.

                                    ARTICLE 2
                            VOTING OF SUBJECT SHARES

        2.1 Agreement. Shareholder hereby agrees that, prior to the Expiration
Date, at any meeting of Atom Shareholders, however called, and in any action
taken by the written consent of Atom Shareholders without a meeting, unless
otherwise directed in writing by Shockwave, Shareholder shall vote the Subject
Shares:

                (a) in favor of the Merger, the execution and delivery by Atom
of the Merger Agreement attached hereto as Exhibit 1 and the adoption and
approval of the terms thereof and in favor of each of the other transactions
contemplated by the Merger Agreement, and any action required in furtherance
hereof and thereof;

                (b) in favor of the amendment and restatement of the Articles of
Incorporation of Atom to provide that no payment of a liquidation preference to
holders of Atom Preferred Stock will be paid in connection with the Merger;

                (c) in favor of the waiver (by amendment of any such agreement
or otherwise), effective as of immediately prior to the effectiveness of the
Merger, of any rights of first refusal, rights of first offer, rights of notice
or rights of co-sale of Shareholder under any agreement applicable to the
Subject Shares, to the extent that the same may apply to the Merger or any other
actions or transactions contemplated by the Merger Agreement; provided, however,
that such waiver will not apply to the shares of Shockwave Common Stock or
Shockwave Preferred Stock issued or issuable to Shareholder in connection with
the Merger; and



                                       2
   77

                (d) against any "Alternative Transaction" (as defined in Section
5.7 of the Merger Agreement).

Prior to the Expiration Date, Shareholder shall not enter into any agreement or
understanding with any Person to vote or give instructions in any manner
inconsistent with clauses (a), (b), (c) or (d) of this Section 2.1.

        2.2 Proxy. Contemporaneously with the execution of this Agreement,
Shareholder shall deliver to Shockwave a proxy with respect to the Subject
Shares in the form and substance attached hereto as Exhibit 2, which proxy shall
be irrevocable to the fullest extent permitted by applicable law (the "PROXY").

                                    ARTICLE 3
                                     WAIVER

        3.1 Appraisal Rights. Shareholder hereby agrees not to exercise any
rights of appraisal and any dissenters' rights that Shareholder may have
(whether under applicable law or otherwise) or could potentially have or acquire
in connection with the Merger.

        3.2 Other Rights. Shareholder hereby waives any rights of first refusal,
rights of first offer, rights to notice or rights of co-sale of Shareholder
under any agreement applicable to the Subject Shares, in each case as the same
may apply to the execution and delivery of the Merger Agreement and the
consummation of the Merger and the other actions and transactions contemplated
by the Merger Agreement; provided, however, that such waiver will not apply to
the shares of Shockwave Common Stock or Shockwave Preferred Stock issued or
issuable to Shareholder in connection with the Merger.

        3.3 Consent and Waiver. Shareholder hereby gives any consents or waivers
that are reasonably required for the consummation of the Merger under the terms
of any agreement to which Shareholder is a party or pursuant to any rights
Shareholder may have.

                                    ARTICLE 4
                  REPRESENTATIONS AND WARRANTIES OF SHAREHOLDER

        Shareholder hereby represents and warrants to Shockwave that the
following representations and warranties will be accurate in all respects at all
times through the Expiration Date and will be accurate in all respects as of the
date of the consummation of the Merger as if made on that date:

        4.1 Due Organization, Authorization, etc. Shareholder has all requisite
power and capacity to execute and deliver this Agreement and to perform
Shareholder's obligations hereunder. This Agreement has been duly executed and
delivered by Shareholder and constitutes a legal, valid and binding obligation
of Shareholder, enforceable against Shareholder in accordance with its terms,
subject to (a) laws of general application relating to bankruptcy, insolvency
and the relief of debtors, and (b) rules of law governing specific performance,
injunctive relief and other equitable remedies.



                                       3
   78

        4.2 No Conflicts, Required Filings and Consents.

                (a) The execution and delivery of this Agreement by Shareholder
do not, and the performance of this Agreement by Shareholder will not: (i)
conflict with or violate any order, decree or judgment applicable to Shareholder
or by which Shareholder or the Subject Shares is bound or affected; or (ii)
result in any breach of or constitute a default (with notice or lapse of time,
or both) under, or give to others or affect any rights of termination,
amendment, acceleration or cancellation of, or result in the creation of any

                                IRREVOCABLE PROXY

        The undersigned shareholder of Atom Corporation, a Washington

and (ii) any and all other shares of capital stock of Atom which the undersigned
may acquire after the date hereof. The shares of the capital stock of Atom
referred to in clauses (i) and (ii) of the immediately preceding sentence are
collectively referred to as the "SHARES." Upon the execution hereof, all prior
proxies given by the undersigned with respect to any of the Shares (other than
any proxies granted to Shockwave) are hereby revoked, and no subsequent proxies
will be given with respect to any of the Shares.

        This proxy is irrevocable, is coupled with an interest and is granted in
connection with that certain Atom Voting Agreement, dated as of the date hereof,
between Shockwave and the undersigned (the "VOTING AGREEMENT"), and is granted
in consideration of Shockwave entering into the Agreement and Plan of
Reorganization dated as of December 14, 2000 between Shockwave and Atom (the

proxy have the meanings ascribed to such terms in the Voting Agreement.

        The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the Expiration Date at
any meeting of Atom Shareholders, however called, or in any action by written
consent of Atom Shareholders:

        (i) in favor of the Merger, the execution and delivery by Atom of the
Merger Agreement attached hereto as Exhibit 1 and the adoption and approval of
the terms thereof and in favor of each of the other transactions contemplated by
the Merger Agreement, and any action required in furtherance hereof and thereof;

        (ii) in favor of the amendment and restatement of the Articles of
Incorporation of Atom to provide that no payment of a liquidation preference to
holders of Atom Preferred Stock will be paid in connection with the Merger;

        (iii) in favor of the waiver (by amendment of any such agreement or
otherwise), effective as of immediately prior to the effectiveness of the
Merger, of any rights of first refusal, rights of first offer, rights of notice
or rights of co-sale of Shareholder under any agreement applicable to the
Subject Shares, to the extent that the same may apply to the Merger or any other
actions or transactions contemplated by the Merger Agreement; provided, however,
that such waiver will not apply to the shares of Shockwave Common Stock or
Shockwave Preferred Stock issued or issuable to Shareholder in connection with
the Merger; and



   83

        (iv) against any "Alternative Transaction" (as defined in Section 5.7 of
the Merger Agreement).

        The undersigned shareholder may vote the Shares on all other matters not
described in the foregoing subparagraphs (i), (ii), (iii) and (iv) above.

        Prior to the Expiration Date, at any meeting of Atom Shareholders,
however called, and in any action by written consent of Atom Shareholders, the

abstain from voting on any matter covered by the foregoing subparagraphs (i),
(ii), (iii) and (iv) above.

        This proxy and any obligation of the undersigned hereunder shall be
binding upon the heirs, successors and assigns of the undersigned (including any
transferee of any of the Shares).

        This proxy shall terminate upon the Expiration Date.

        RE:     INVESTMENT REPRESENTATION LETTER [to be executed by accredited
                investors]

Ladies and Gentlemen:

        The undersigned ("SHAREHOLDER") holds shares of Common Stock and/or
Preferred Stock of Atom Corporation, a Washington corporation ("ATOM"). Pursuant
to that certain Agreement and Plan of Reorganization dated as of December 14,
2000 (the "MERGER AGREEMENT") by and between Shockwave.com, Inc., a Delaware
corporation ("SHOCKWAVE"), and Atom, Atom will be merged with and into Shockwave
(the "MERGER"), with Shockwave to be the surviving corporation of the Merger. In
connection with the Merger, Shockwave will issue to Atom Shareholders Shockwave
Common Stock and Shockwave Series C Preferred Stock (the "MERGER SHARES") in a
private placement effected in reliance on an exemption from the registration
requirements of the Securities Act of 1933, as amended (the "SECURITIES ACT"),
provided by Section 4(2) of the Securities Act and/or Regulation D promulgated
under the Securities Act, and exemptions from the qualification requirements of
applicable state law. Shareholder is a shareholder of Atom, and Shareholder
acknowledges and agrees that Shockwave is relying on the truth and accuracy of
the representations and warranties made by Shareholder in this Investment
Representation Letter in order to rely on the exemption described above. Unless
otherwise defined herein, all capitalized terms used herein shall have the same
meanings given to such terms in the Merger Agreement.

        Shareholder hereby makes the following representations, warranties and
agreements to Shockwave, each of which representations and warranties contained
in the following Sections of this Investment Representation Letter are true and
correct as to Shareholder as of the date hereof and will be true and correct on
and as of the Closing Date.

        1. Binding Agreement; Authority. This Investment Representation Letter
constitutes Shareholder's valid and legally binding obligation, enforceable in
accordance with its terms, except as may be limited by (a) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights generally, and (b) rules of
law and equity governing specific performance, injunctive relief and other
equitable remedies. Shareholder has executed, delivered and performed
his/her/its obligations under, and has all requisite legal power, authority and
capacity to execute, deliver and perform his/her/its obligations under, this
Investment Representation Letter. The execution, delivery and performance by
Shareholder of this Investment Representation Letter have been duly and validly
approved and authorized by all necessary corporate, trust, partnership or
custodial action required by applicable law.

        2. Title; No Other Securities; Waiver. Shareholder has good and
marketable title to that number of shares of Atom Common Stock and/or Atom
Preferred Stock as set forth beside his/her/its name on Schedule 3.4(a)-1 to the
Atom Disclosure Letter (the "SUBJECT SHARES"), free and clear of all mortgages,
deeds of trust, security interests, pledges, liens, title retention devices,
collateral assignments,



   85

claims, charges, restrictions or other encumbrances of any kind. Except as set
forth in the Atom Disclosure Schedule, Shareholder has no interest in, or right
of any kind to, any other securities of Atom, including any options, warrants,
convertible securities or other securities, calls, commitments, conversion
privileges, preemptive rights, rights of first refusal, rights of first offer or
other rights or agreements outstanding to purchase or otherwise acquire (whether
directly or indirectly) any shares of Atom capital stock or any securities
convertible into or exchangeable for any shares of Atom capital stock or
obligating Atom to grant, issue, extend or enter into any such option, warrant,
convertible security or other security, call, commitment, conversion privilege,
preemptive right, right of first refusal, right of first offer or other right or
agreement. Shareholder hereby waives any rights of first refusal, rights of
first offer, rights to notice, rights of co-sale, tag-along rights, information
rights, registration rights, preemptive rights, rights of redemption or
repurchase, and similar rights of Shareholder under any agreement, arrangement
or understanding applicable to the Subject Shares, in each case as the same may
apply to the execution and delivery of the Merger Agreement and the consummation
of the Merger and the other actions and transactions contemplated by the Merger
Agreement.

        3. Approval of Agreement; Merger. Shareholder hereby approves the terms
of the Merger Agreement and the Merger, and agrees to be bound by the
indemnification obligations of Shareholder as security for the performance of
the obligations of Shareholder under Article 11 of the Merger Agreement.
Shareholder further approves the designation of and designates _____________ as
the representative of Shareholder (the "REPRESENTATIVE") and as the
attorney-in-fact and agent for and on behalf of Shareholder with respect to
claims for indemnification under Article 11 and the taking by the Representative
of any and all actions and the making of any decisions required or permitted to
be taken by the Representative under the Merger Agreement in accordance with
Article 11 thereof.

        4. Purchase for Own Account. The Merger Shares to be issued to
Shareholder hereunder will be acquired for investment for Shareholder's own
account, not as a nominee or agent, and not with a view to the public resale or
distribution thereof within the meaning of the Securities Act, and Shareholder
has no present intention of selling, granting any participation in, or otherwise
distributing the same.

        5. Disclosure of Information. Shareholder has received or has had full
access to all the information Shareholder considers necessary or appropriate to
make an informed investment decision with respect to the Merger Shares to be
issued to Shareholder under the Merger Agreement. Shareholder has had an
opportunity to ask questions and receive answers from Shockwave and Atom
regarding the terms and conditions of the offering of Merger Shares pursuant to
the Merger Agreement and to obtain additional information (to the extent
Shockwave possessed such information or could acquire it without unreasonable
effort or expense) necessary to verify any information furnished to Shareholder
or to which Shareholder had access.

        6. Investment Experience. Shareholder understands that the acquisition
of the Merger Shares pursuant to the Merger Agreement involves substantial risk.
Shareholder acknowledges that Shareholder can bear the economic risk of
Shareholder's investment in the Merger Shares, and has such knowledge and
experience in financial or business matters that Shareholder is capable of
evaluating the merits and risks of this investment in the Merger Shares and
protecting his/her/its own interests in connection with this investment.
Shareholder hereby represents that he/she/it is an "accredited investor" as such
term is defined under Section 501(a) of Regulation D promulgated under the
Securities Act.

        7. Merger Shares. Shareholder understands that the Merger Shares are
characterized as "restricted securities" under the Securities Act inasmuch as
they are being acquired from Shockwave in a



                                       2
   86

transaction not involving a public offering and that under the Securities Act
and applicable regulations thereunder such securities may be resold without
registration under the Securities Act only in certain limited circumstances. In
this connection, Shareholder represents that Shareholder is familiar with
Securities Exchange Commission Rule 144 as presently in effect, and understands
the resale limitations imposed thereby and by the Securities Act. Shareholder
understands that, except as set forth in Section 2.7 of the Merger Agreement and
the Investors' Rights Agreement, Shockwave is under no obligation to register
any of the Merger Shares. Shareholder agrees to be bound by the limitations and
restrictions set forth in Section 2.7 of the Merger Agreement and the Investors'
Rights Agreement while exercising any of the rights granted to Shareholder
therein.

        8. Further Limitations on Disposition. Without in any way limiting the
representations set forth above, Shareholder further agrees not to make any
disposition of all or any portion of the Merger Shares issued to Shareholder in
the Merger unless and until:

                (a) there is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

                (b) Shareholder shall have notified Shockwave of the proposed
disposition and shall have furnished Shockwave with a statement of the
circumstances surrounding the proposed disposition, and, at the expense of
Shareholder or Shareholder's transferee, with an opinion of counsel, reasonably
satisfactory to Shockwave, that such disposition will not require registration
of such securities under the Securities Act.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required for the transfer
of such shares by gift, will or intestate succession by Atom Shareholder to his
or her spouse or lineal descendants or ancestors or any charitable organization
or any trust for any of the foregoing, personal representative (such as an
executor of Shareholder's will), custodian or conservator of Shareholder in the
case of the death, bankruptcy or adjudication of incompetency of Shareholder,
partners of Shareholder if Shareholder is a partnership or members of
Shareholder if Shareholder is a limited liability company (each a "PERMITTED
TRANSFEREE"); provided that the Permitted Transferee agrees in writing to be
subject to the terms of this Section 8 to the same extent as if the transferee
were an original Shareholder hereunder.

        9. Legends. Shareholder acknowledges and understands that the
certificates evidencing the Merger Shares issued in the Merger will bear the
legend set forth below:

        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES
        LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
        TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT
        AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS,
        PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE
        AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS
        INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE
        SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
        SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR
        RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES
        LAWS.



                                       3
   87

The legend set forth above shall be removed by Shockwave from any certificate
evidencing Merger Shares upon receipt by Shockwave of an opinion by its counsel
that a registration statement under the Securities Act is at that time in effect
with respect to the legended security or upon delivery to Shockwave of an
opinion by its counsel, or counsel reasonably satisfactory to Shockwave, that
such security can be freely transferred in a public sale without such a
registration statement being in effect.

        10. Stop-Transfer Instructions. Shareholder agrees that to ensure
compliance with the restrictions imposed by this Investment Representation
Letter, Shockwave may issue appropriate "stop-transfer" instructions to its
transfer agent, if any, and if Shockwave transfers its own securities, it may
make appropriate notations to the same effect in its own records.

        11. Refusal to Transfer. Shockwave will not be required to (a) register
a transfer on its books any Merger Shares that have been sold or otherwise
transferred in violation of any of the provisions of this Investment
Representation Letter, or (b) treat as owner of such Merger Shares, or to accord
the right to vote or pay dividends, to any purchaser or other trustee to whom
such Merger Shares have been so transferred.

        12. Compliance With Laws and Regulations. The issuance and transfer of
the Merger Shares will be subject to and conditioned upon compliance by
Shockwave and Shareholder with all applicable state and federal laws and
regulations and with all applicable requirements of any stock exchange or
automated quotation system on which Merger Shares may be listed or quoted at the
time of such issuance or transfer.

        13. Entire Agreement. This Investment Representation Letter and the
specific provisions of the Merger Agreement by which Shareholder has agreed to
be bound constitute the entire agreement and understanding of the parties with
respect to the subject matter of this Investment Representation Letter, and
supersede all prior understandings and agreements, whether oral or written,
between or among the parties hereto with respect to the specific subject matter
hereof.

        14. Construction of Agreement. This Investment Representation Letter has
been negotiated by the respective parties hereto and their attorneys and the
language hereof will not be construed for or against either party.

        15. Governing Law. The internal laws of the State of California
(irrespective of its choice of law principles) will govern the validity of this
Investment Representation Letter, the construction of its terms, and the
interpretation and enforcement of the rights and duties of the parties hereto.

        16. Assignment; Binding Upon Successors and Assigns. Neither party
hereto may assign any of its rights or obligations hereunder without the prior
written consent of the other party hereto. This Investment Representation Letter
will be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

        17. Severability. If any provision of this Investment Representation
Letter, or the application thereof, will for any reason and to any extent be
invalid or unenforceable, then the remainder of this Investment Representation
Letter and the application of such provision to other persons or circumstances
will be interpreted so as reasonably to effect the intent of the parties hereto.



                                       4
   88

        18. Counterparts. This Investment Representation Letter may be executed
in any number of counterparts, each of which will be an original as regards any
party whose signature appears thereon and all of which together will constitute
one and the same instrument.

        19. Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party hereunder will be deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such party, and the exercise of any one remedy will not preclude the exercise
of any other. The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this Investment Representation Letter
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to seek an
injunction or injunctions to prevent breaches of this Investment Representation
Letter and to enforce specifically the terms and provisions hereof in any court
of the United States or any state having jurisdiction.

        20. Amendment and Waivers. Any term or provision of this Investment
Representation Letter may be amended, and the observance of any term of this
Investment Representation Letter may be waived (either generally or in a
particular instance and either retroactively or prospectively), only by a
writing signed by the party to be bound thereby.

                                            Very truly yours,

        RE:     INVESTMENT REPRESENTATION LETTER [to be executed by unaccredited
                investors]

Ladies and Gentlemen:

        The undersigned ("SHAREHOLDER") holds shares of Common Stock and/or
Preferred Stock of Atom Corporation, a Washington corporation ("ATOM"). Pursuant
to that certain Agreement and Plan of Reorganization dated as of December 14,
2000 (the "MERGER AGREEMENT") by and between Shockwave.com, Inc., a Delaware
corporation ("SHOCKWAVE"), and Atom, Atom will be merged with and into Shockwave
(the "MERGER"), with Shockwave to be the surviving corporation of the Merger. In
connection with the Merger, Shockwave will issue to Atom Shareholders Shockwave
Common Stock and Shockwave Series C Preferred Stock (the "MERGER SHARES") in a
private placement effected in reliance on an exemption from the registration
requirements of the Securities Act of 1933, as amended (the "SECURITIES ACT"),
provided by Section 4(2) of the Securities Act and/or Regulation D promulgated
under the Securities Act, and exemptions from the qualification requirements of
applicable state law. Shareholder is a shareholder of Atom, and Shareholder
acknowledges and agrees that Shockwave is relying on the truth and accuracy of
the representations and warranties made by Shareholder in this Investment
Representation Letter in order to rely on the exemption described above. Unless
otherwise defined herein, all capitalized terms used herein shall have the same
meanings given to such terms in the Merger Agreement.

        Shareholder hereby makes the following representations, warranties and
agreements to Shockwave, each of which representations and warranties contained
in the following Sections of this Investment Representation Letter are true and
correct as to Shareholder as of the date hereof and will be true and correct on
and as of the Closing Date.

        1. Binding Agreement; Authority. This Investment Representation Letter
constitutes Shareholder's valid and legally binding obligation, enforceable in
accordance with its terms, except as may be limited by (a) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights generally, and (b) rules of
law and equity governing specific performance, injunctive relief and other
equitable remedies. Shareholder has executed, delivered and performed
his/her/its obligations under, and has all requisite legal power, authority and
capacity to execute, deliver and perform his/her/its obligations under, this
Investment Representation Letter. The execution, delivery and performance by
Shareholder of this Investment Representation Letter have been duly and validly
approved and authorized by all necessary corporate, trust, partnership or
custodial action required by applicable law.

        2. Title; No Other Securities; Waiver. Shareholder has good and
marketable title to that number of shares of Atom Common Stock and/or Atom
Preferred Stock as set forth beside his/her/its



   90

name on Schedule 3.4(a)-1 to the Atom Disclosure Letter (the "SUBJECT SHARES"),
free and clear of all mortgages, deeds of trust, security interests, pledges,
liens, title retention devices, collateral assignments, claims, charges,
restrictions or other encumbrances of any kind. Except as set forth in the Atom
Disclosure Schedule, Shareholder has no interest in, or right of any kind to,
any other securities of Atom, including any options, warrants, convertible
securities or other securities, calls, commitments, conversion privileges,
preemptive rights, rights of first refusal, rights of first offer or other
rights or agreements outstanding to purchase or otherwise acquire (whether
directly or indirectly) any shares of Atom capital stock or any securities
convertible into or exchangeable for any shares of Atom capital stock or
obligating Atom to grant, issue, extend or enter into any such option, warrant,
convertible security or other security, call, commitment, conversion privilege,
preemptive right, right of first refusal, right of first offer or other right or
agreement. Shareholder hereby waives any rights of first refusal, rights of
first offer, rights to notice, rights of co-sale, tag-along rights, information
rights, registration rights, preemptive rights, rights of redemption or
repurchase, and similar rights of Shareholder under any agreement, arrangement
or understanding applicable to the Subject Shares, in each case as the same may
apply to the execution and delivery of the Merger Agreement and the consummation
of the Merger and the other actions and transactions contemplated by the Merger
Agreement.

        3. Approval of Agreement; Merger. Shareholder hereby approves the terms
of the Merger Agreement and the Merger, and agrees to be bound by the
indemnification obligations of Shareholder as security for the performance of
the obligations of Shareholder under Article 11 of the Merger Agreement.
Shareholder further approves the designation of and designates _____________ as
the representative of Shareholder (the "REPRESENTATIVE") and as the
attorney-in-fact and agent for and on behalf of Shareholder with respect to
claims for indemnification under Article 11 and the taking by the Representative
of any and all actions and the making of any decisions required or permitted to
be taken by the Representative under the Merger Agreement in accordance with
Article 11 thereof.

        4. Purchase for Own Account. The Merger Shares to be issued to
Shareholder hereunder will be acquired for investment for Shareholder's own
account, not as a nominee or agent, and not with a view to the public resale or
distribution thereof within the meaning of the Securities Act, and Shareholder
has no present intention of selling, granting any participation in, or otherwise
distributing the same.

        5. Disclosure of Information. Shareholder has received or has had full
access to all the information Shareholder considers necessary or appropriate to
make an informed investment decision with respect to the Merger Shares to be
issued to Shareholder under the Merger Agreement. Shareholder has had an
opportunity to ask questions and receive answers from Shockwave and Atom
regarding the terms and conditions of the offering of Merger Shares pursuant to
the Merger Agreement and to obtain additional information (to the extent
Shockwave possessed such information or could acquire it without unreasonable
effort or expense) necessary to verify any information furnished to Shareholder
or to which Shareholder had access.

        6. Investment Experience. Shareholder understands that the acquisition
of the Merger Shares pursuant to the Merger Agreement involves substantial risk.
Shareholder acknowledges that Shareholder can bear the economic risk of
Shareholder's investment in the Merger Shares, and has such knowledge and
experience in financial or business matters that Shareholder is capable of
evaluating the merits and risks of this investment in the Merger Shares and
protecting his/her/its own interests in connection with this investment.



                                       2
   91

        7. Appointment of Purchaser Representative. Shareholder hereby appoints
_______________ to act as a "purchaser representative," as that term is used in
Rule 501(h) promulgated under the Securities Act, for the purpose of making
Shareholder's decision to exchange Atom Common Stock and/or Atom Preferred Stock
pursuant to the Merger Agreement.

        8. Merger Shares. Shareholder understands that the Merger Shares are
characterized as "restricted securities" under the Securities Act inasmuch as
they are being acquired from Shockwave in a transaction not involving a public
offering and that under the Securities Act and applicable regulations thereunder
such securities may be resold without registration under the Securities Act only
in certain limited circumstances. In this connection, Shareholder represents
that Shareholder is familiar with Securities Exchange Commission Rule 144 as
presently in effect, and understands the resale limitations imposed thereby and
by the Securities Act. Shareholder understands that, except as set forth in
Section 2.7 of the Merger Agreement and the Investors' Rights Agreement,
Shockwave is under no obligation to register any of the Merger Shares.
Shareholder agrees to be bound by the limitations and restrictions set forth in
Section 2.7 of the Merger Agreement and the Investors' Rights Agreement while
exercising any of the rights granted to Shareholder therein.

        9. Further Limitations on Disposition. Without in any way limiting the
representations set forth above, Shareholder further agrees not to make any
disposition of all or any portion of the Merger Shares issued to Shareholder in
the Merger unless and until:

                (a) there is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

                (b) Shareholder shall have notified Shockwave of the proposed
disposition and shall have furnished Shockwave with a statement of the
circumstances surrounding the proposed disposition, and, at the expense of
Shareholder or Shareholder's transferee, with an opinion of counsel, reasonably
satisfactory to Shockwave, that such disposition will not require registration
of such securities under the Securities Act.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required for the transfer
of such shares by gift, will or intestate succession by Atom Shareholder to his
or her spouse or lineal descendants or ancestors or any charitable organization
or any trust for any of the foregoing, personal representative (such as an
executor of Shareholder's will), custodian or conservator of Shareholder in the
case of the death, bankruptcy or adjudication of incompetency of Shareholder,
partners of Shareholder if Shareholder is a partnership or members of
Shareholder if Shareholder is a limited liability company (each, a "PERMITTED
TRANSFEREE"); provided that the Permitted Transferee agrees in writing to be
subject to the terms of this Section 9 to the same extent as if the transferee
were an original Atom Shareholder hereunder.

        10. Legends. Shareholder acknowledges and understands that the
certificates evidencing the Merger Shares issued in the Merger will bear the
legend set forth below:

        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES
        LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
        TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT
        AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS,
        PURSUANT



                                       3
   92

        TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT
        THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR
        AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE
        AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER
        TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH
        THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

The legend set forth above shall be removed by Shockwave from any certificate
evidencing Merger Shares upon receipt by Shockwave of an opinion by its counsel,
that a registration statement under the Securities Act is at that time in effect
with respect to the legended security or upon delivery to Shockwave of an
opinion by its counsel, or counsel reasonably satisfactory to Shockwave, that
such security can be freely transferred in a public sale without such a
registration statement being in effect.

        11. Stop-Transfer Instructions. Shareholder agrees that to ensure
compliance with the restrictions imposed by this Investment Representation
Letter, Shockwave may issue appropriate "stop-transfer" instructions to its
transfer agent, if any, and if Shockwave transfers its own securities, it may
make appropriate notations to the same effect in its own records.

        12. Refusal to Transfer. Shockwave will not be required to (a) register
a transfer on its books any Merger Shares that have been sold or otherwise
transferred in violation of any of the provisions of this Investment
Representation Letter, or (b) treat as owner of such Merger Shares, or to accord
the right to vote or pay dividends, to any purchaser or other trustee to whom
such Merger Shares have been so transferred.

        13. Compliance With Laws and Regulations. The issuance and transfer of
the Merger Shares will be subject to and conditioned upon compliance by
Shockwave and Shareholder with all applicable state and federal laws and
regulations and with all applicable requirements of any stock exchange or
automated quotation system on which Shockwave's capital stock may be listed or
quoted at the time of such issuance or transfer.

        14. Entire Agreement. This Investment Representation Letter and the
specific provisions of the Merger Agreement by which Shareholder has agreed to
be bound constitute the entire agreement and understanding of the parties with
respect to the subject matter of this Investment Representation Letter, and
supersede all prior understandings and agreements, whether oral or written,
between or among the parties hereto with respect to the specific subject matter
hereof.

        15. Construction of Agreement. This Investment Representation Letter has
been negotiated by the respective parties hereto and their attorneys and the
language hereof will not be construed for or against either party.

        16. Governing Law. The internal laws of the State of California
(irrespective of its choice of law principles) will govern the validity of this
Investment Representation Letter, the construction of its terms, and the
interpretation and enforcement of the rights and duties of the parties hereto.

        17. Assignment; Binding Upon Successors and Assigns. Neither party
hereto may assign any of its rights or obligations hereunder without the prior
written consent of the other party hereto. This Investment Representation Letter
will be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns.



                                       4
   93

        18. Severability. If any provision of this Investment Representation
Letter, or the application thereof, will for any reason and to any extent be
invalid or unenforceable, then the remainder of this Investment Representation
Letter and the application of such provision to other persons or circumstances
will be interpreted so as reasonably to effect the intent of the parties hereto.

        19. Counterparts. This Investment Representation Letter may be executed
in any number of counterparts, each of which will be an original as regards any
party whose signature appears thereon and all of which together will constitute
one and the same instrument.

        20. Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party hereunder will be deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such party, and the exercise of any one remedy will not preclude the exercise
of any other. The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this Investment Representation Letter
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to seek an
injunction or injunctions to prevent breaches of this Investment Representation
Letter and to enforce specifically the terms and provisions hereof in any court
of the United States or any state having jurisdiction.

        21. Amendment and Waivers. Any term or provision of this Investment
Representation Letter may be amended, and the observance of any term of this
Investment Representation Letter may be waived (either generally or in a
particular instance and either retroactively or prospectively) only by a writing
signed by the party to be bound thereby.


                                       Very truly yours,

                           SHOCKWAVE VOTING AGREEMENT


        This SHOCKWAVE VOTING AGREEMENT (this "AGREEMENT") is entered into as of
December 14, 2000 (the "AGREEMENT DATE") by and between Atom Corporation, a
Washington corporation ("Atom") and [name of shareholder] ("SHAREHOLDER").

                                    RECITALS

        A. Concurrently with the execution of this Agreement, Shockwave.com,
Inc., a Delaware corporation ("SHOCKWAVE"), and Atom are entering into an
Agreement and Plan of Reorganization dated as of December 14, 2000 (the "MERGER
AGREEMENT"), which provides (subject to the conditions set forth therein) for
the merger of Atom with and into Shockwave (the "MERGER") with Shockwave to
survive the Merger. Upon the effectiveness of the Merger, the outstanding shares
of Atom Common Stock and Atom Preferred Stock will be converted into the right
to receive Shockwave Common Stock and Shockwave Series C Preferred Stock, and
outstanding Atom Options and Atom Warrants to purchase shares of Atom Common
Stock and Atom Preferred Stock will be converted into Shockwave Options and
Shockwave Warrants, all as more particularly set forth in the Merger Agreement.
Capitalized terms used but not otherwise defined in this Agreement will have the
same meanings ascribed to such terms in the Merger Agreement.

        B. As of the Agreement Date, Shareholder owns in the aggregate
(including shares held both beneficially and of record and other shares held
either beneficially or of record) the number of shares of Shockwave Common Stock
and Shockwave Preferred Stock set forth below Shareholder's name on the
signature page of this Agreement (all such shares, together with any shares of
Shockwave Common Stock and Shockwave Preferred Stock or any other shares of
capital stock of Shockwave that may hereafter be acquired by Shareholder, being
collectively referred to herein as the "SUBJECT SHARES"). If, between the
Agreement Date and the Expiration Date (as defined in Section 1.1(b) below), the
outstanding shares of Shockwave's capital stock are changed into a different
number or class of shares by reason of any stock split, stock dividend, reverse
stock split, reclassification, recapitalization or other similar transaction,
then the shares constituting the Subject Shares shall be appropriately adjusted,
and shall include any shares or other securities of Shockwave issued on, or with
respect to, the Subject Shares in such a transaction.

        C. As a condition to the willingness of Atom to enter into the Merger
Agreement, Atom has required that Shareholder agree, and in order to induce Atom
to enter into the Merger Agreement, Shareholder has agreed, to enter into this
Agreement.

        In consideration of the facts recited above, the parties to this
Agreement, intending to be legally bound by this Agreement, now hereby agree as
follows:

        1.1 No Transfer of Voting Rights.

                (a) Shareholder covenants and agrees that, prior to the

respect to any of the Subject Shares, except for the Proxy called for by Section

                (b) As used in this Agreement, the term "EXPIRATION DATE" shall

agreement relating to any of the foregoing with respect to the Subject Shares,
except in connection with the Merger.

Shares:

                (a) in favor of the Merger, the execution and delivery by
Shockwave of the Merger Agreement and the adoption and approval of the terms
thereof and in favor of each of the other transactions contemplated by the
Merger Agreement and any action required in furtherance hereof and thereof;

                (b) in favor of the amendment and restatement of the Certificate
of Incorporation of Shockwave in form and substance attached hereto as Exhibit
1;

                (c) in favor of the waiver (by amendment of any such agreement
or otherwise), effective as of immediately prior to the effectiveness of the
Merger, of any rights of first refusal, rights of first offer or rights of
notice of Shareholder under any agreement applicable to the Subject Shares, to
the extent that the same may apply to the Merger or any other actions or
transactions contemplated by the Merger Agreement; and

                (d) against any other action which is intended, or would
reasonably be expected to, impede, interfere with, delay, postpone, discourage
or adversely affect the Merger, the other transactions contemplated by the
Merger Agreement or any action required in furtherance hereof or thereof.



                                       2

in connection with the Merger.

        3.2 Other Rights. Shareholder hereby waives any rights of first refusal,
rights of first offer or rights to notice of Shareholder under any agreement
applicable to the Subject Shares, in each case as the same may apply to the
execution and delivery of the Merger Agreement and the consummation of the
Merger and the other actions and transactions contemplated by the Merger
Agreement.

        3.3 Consent and Waiver. Shareholder hereby gives any consents or waivers
that are reasonably required for the consummation of the Merger under the terms
of any agreement to which Shareholder is a party or pursuant to any rights
Shareholder may have.

                                    ARTICLE 4

of the consummation of the Merger as if made on that date:

        4.1 Due Authorization, etc. Shareholder has all requisite power and
capacity to execute and deliver this Agreement and to perform Shareholder's
obligations hereunder. This Agreement has been duly executed and delivered by

        4.2 No Conflicts, Required Filings and Consents.

                (a) The execution and delivery of this Agreement by Shareholder
do not, and the performance of this Agreement by Shareholder will not: (i)
conflict with or violate any



                                       3
   97

order, decree or judgment applicable to Shareholder or by which Shareholder or
the Subject Shares is bound or affected; or (ii) result in any breach of or
constitute a default (with notice or lapse of time, or both) under, or give to
others or affect any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of any lien, restriction, adverse
claim, option on, right to acquire, or any encumbrance or security interest in
or to, any of the Subject Shares, except as disclosed in the Shockwave
Disclosure Letter.

                (b) The execution and delivery of this Agreement by Shareholder
do not, and the performance of this Agreement by Shareholder will not, require
any notice to or consent of any third party.

        4.3 Title to Subject Shares. As of the Agreement Date, Shareholder
beneficially or of record owns the Subject Shares set forth under Shareholder's

either beneficially or of record, any shares of capital stock of Shockwave or
rights to acquire any shares of capital stock of Shockwave, other than the
Subject Shares set forth below Shareholder's name on the signature page hereof
(other than shares subject to options).

                                    ARTICLE 5

herein, neither this Agreement nor any of the rights, interests or obligations
hereunder shall be assigned by either of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
party. Subject to the preceding sentence, this Agreement shall be binding upon
and shall inure to the benefit of (a) Shareholder and Shareholder's heirs,

Notwithstanding anything contained in this Agreement to the contrary, nothing in
this Agreement, expressed or implied, is intended to confer on any person or
entity other than the parties hereto or their respective heirs, successors and
assigns, any rights, remedies, obligations or liabilities under or by reason of
this Agreement.

        5.4 Severability. If any provision of this Agreement, or the application
thereof, will for any reason and to any extent be invalid or unenforceable, then
the remainder of this Agreement and application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto.

Preferred Stock shall be entitled to receive dividends, when as and if declared
by the Board, out of any funds and assets of the Corporation legally available
therefor, prior and in preference to the payment of any dividends on the Common
Stock. However, no dividends (other than a Common Stock Dividend) shall be paid
with respect to the Common Stock during any calendar year unless dividends for
each series of Preferred Stock shall have first been paid or declared and set
apart for payment to the holders of each such series of Preferred Stock,
respectively, during that calendar year in at least an amount per share of
Preferred Stock determined by multiplying the (a) dividend to be paid on one
share of Common Stock by (b) the number of shares of Common Stock then issuable
upon conversion of such share of Preferred Stock pursuant to Section 5;
provided, however, that this restriction shall not apply to Permitted
Repurchases. Payments of any dividends to the holders of each such series of
Preferred Stock shall be paid pro rata, on an equal priority, pari passu basis.
Dividends on the Preferred Stock shall not be mandatory or cumulative, and no
rights or interest shall accrue to the holders of the Preferred Stock by reason
of the fact that the Corporation shall fail to declare or pay dividends on the
Preferred Stock in any amount in any calendar year or any fiscal year of the
Corporation, whether or not the earnings of the Corporation in any calendar year
or fiscal year were sufficient to pay dividends.

                2.2 Non-Cash Dividends. Whenever a dividend provided for in this
Section 2 shall be payable in property other than cash, the value of such
dividend shall be deemed to be the fair market value of such property as
determined in good faith by the Board.

        3. LIQUIDATION RIGHTS. In the event of any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the funds and
assets that may be legally distributed to the Corporation's stockholders (the
"AVAILABLE FUNDS AND ASSETS") shall be distributed to stockholders in the
following manner:

                3.1 Liquidation Preferences.

                (a) Subject to clause 3.1(b) below, the holders of each share of
Preferred Stock then outstanding shall be entitled to be paid, out of the
Available Funds and Assets, and prior and in preference to any payment or
distribution (or any setting apart of any payment or distribution) of any
Available Funds and Assets on any shares of Common Stock, an amount per share
equal to the Original Issue Price for each such series of Preferred Stock,
respectively, plus



                                       3
   108

all declared but unpaid dividends thereon. If upon any liquidation, dissolution
or winding up of the Corporation, the Available Funds and Assets shall be
insufficient to permit the payment to holders of the Preferred Stock of their
full preferential amounts described in this subsection, then all Available Funds
and Assets shall be distributed among the holders of the then outstanding
Preferred Stock pro rata, on an equal priority, pari passu basis, according to
their respective liquidation preferences as set forth herein (with the
distributions to the holders of then outstanding Series C Preferred Stock made
in accordance with the provisions of clause 3.1(b) below).

                (b) Liquidation Preference Payment to Series C Preferred Stock.

                        (i) To the extent that any payment or distribution is to
be made to holders of Series C Preferred Stock pursuant to this Section 3, the
holders of Series C-3 Preferred Stock shall be entitled to receive, prior and in
preference to any payment or distribution to the holders of Series C-1 Preferred
Stock or Series C-2 Preferred Stock, by reason of their ownership thereof, an
amount per share equal to the Original Issue Price for each such series of
Preferred Stock, respectively, plus all declared but unpaid dividends thereon.
If upon any liquidation, dissolution or winding up of the Corporation the
Available Funds and Assets allocated to the Series C Preferred Stock shall be
insufficient to permit the payment to holders of Series C-3 Preferred Stock of
their full preferential amounts described in this clause b(i), then all
Available Funds and Assets to be distributed to holders of Series C Preferred
Stock shall be distributed among the holders of the then outstanding Series C-3
Preferred Stock pro rata, on an equal priority, pari passu basis, according to
their respective liquidation preferences as set forth herein.

                        (ii) Upon the completion of the distribution required by
clause (b)(i) above, if Available Funds and Assets remain, then the holders of
Series C-2 Preferred Stock shall be entitled to receive, prior and in preference
to any payment or distribution to the holders of Series C-1 Preferred Stock, by
reason of their ownership thereof, an amount per share equal to the Original
Issue Price per share for each share of Series C-2 Preferred Stock then held by
them, plus all declared but unpaid dividends thereon. If upon any liquidation,
dissolution or winding up of the Corporation the Available Funds and Assets
allocated to the Series C Preferred Stock shall be insufficient to permit the
payment to holders of Series C-2 Preferred Stock of their full preferential
amounts described in this clause b(ii), then all Available Funds and Assets to
be distributed to holders of Series C-2 Preferred Stock shall be distributed
ratably among the holders of Series C-2 Preferred Stock in proportion to the
preferential amount each holder is otherwise entitled to receive.

                        (iii) Upon the completion of the distribution required
by clause (b)(ii) above, if Available Funds and Assets remain, then the holders
of Series C-1 Preferred Stock shall be entitled to receive, prior and in
preference to any payment or distribution to the holders of Common Stock, by
reason of their ownership thereof, an amount per share equal to the Original
Issue Price per share for each share of Series C-1 Preferred Stock then held by
them, plus all declared but unpaid dividends thereon. If upon any liquidation,
dissolution or winding up of the Corporation the Available Funds and Assets
allocated to the Series C Preferred Stock shall be insufficient to permit the
payment to holders of Series C-1 Preferred Stock of their full



                                       4
   109

preferential amounts described in this clause b(iii), then all Available Funds
and Assets to be distributed to holders of Series C-1 Preferred Stock shall be
distributed ratably among the holders of Series C-1 Preferred Stock in
proportion to the preferential amount each holder is otherwise entitled to
receive.

                3.2 No Participation Rights. If at the closing or effective time
of the liquidation event, shares of Common Stock of the Corporation are
outstanding and there are any Available Funds and Assets remaining after the
payment or distribution (or the setting aside for payment or distribution) to
the holders of the Preferred Stock of their full preferential amounts described
above in Section 3.1, then all such remaining Available Funds and Assets shall
be distributed among the holders of the then outstanding Common Stock pro rata
according to the number of shares of Common Stock held by such holders. If at
the closing or effective time of the liquidation event, no shares of Common
Stock of the Corporation are outstanding and there are any Available Funds and
Assets remaining after the payment or distribution (or the setting aside for
payment or distribution) to the holders of the Preferred Stock of their full
preferential amounts described above in Section 3.1, then all remaining
Available Funds and Assets shall be distributed among the holders of the then
outstanding Preferred Stock pro rata according to the greatest whole number of
shares of Common Stock then issuable to each holder upon conversion in full of
such shares of Preferred Stock pursuant to Section 5.

                3.3 Merger or Sale of Assets. Any (i) acquisition of the
Corporation by another entity by means of any transaction or series of related
transactions (including, without limitation, any reorganization, merger or
consolidation) that results in the transfer of fifty percent (50%) or more of
the outstanding voting power of the Corporation; or (ii) sale of all or
substantially all of the assets of the Corporation, shall each be deemed to be a
liquidation, dissolution or winding up of the Corporation as those terms are
used in this Section 3.

                3.4 Non-Cash Consideration. If any assets of the Corporation
distributed to stockholders in connection with any liquidation, dissolution, or
winding up of the Corporation are other than cash, then the value of such assets
shall be their fair market value as determined by the Board of Directors in good
faith, except that any securities to be distributed to stockholders in a
liquidation, dissolution, or winding up of the Corporation shall be valued as
follows:

                        (a) The method of valuation of securities not subject to
investment letter or other similar restrictions on free marketability shall be
as follows:

                                (i) if the securities are then traded on a
national securities exchange or the Nasdaq National Market (or a similar
national quotation system), then the value shall be deemed to be the average of
the closing prices of the securities on such exchange or system over the thirty
(30) day period ending three (3) days prior to the distribution; and

                                (ii) if (i) above does not apply but the
securities are actively traded over-the-counter, then the value shall be deemed
to be the average of the closing bid prices over the thirty (30) day period
ending three (3) days prior to the distribution; and



                                       5
   110

                                (iii) if there is no active public market, then
the value shall be the fair market value thereof, as determined in good faith by
the Board of Directors of the Corporation.

                        (b) The method of valuation of securities subject to
investment letter or other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in
subparagraphs (a)(i), (ii) or (iii) of this subsection to reflect the
approximate fair market value thereof, as determined in good faith by the Board
of Directors.

        4. VOTING RIGHTS.

                4.1 Common Stock. Each holder of shares of Common Stock shall be
entitled to one (1) vote for each share thereof held.

                4.2 Preferred Stock. Each holder of shares of Preferred Stock
shall be entitled to the number of votes equal to the number of whole shares of
Common Stock into which such shares of Preferred Stock could be converted
pursuant to the provisions of Section 5 below at the record date for the
determination of the stockholders entitled to vote on such matters or, if no
such record date is established, the date such vote is taken or any written
consent of stockholders is solicited. Fractional votes shall not, however, be
permitted and any fractional voting rights otherwise available on an
as-converted to Common Stock basis shall be rounded to the nearest whole number
of votes.

                4.3 General. Subject to the other provisions of this Certificate
of Incorporation, each holder of Preferred Stock shall have full voting rights
and powers equal to the voting rights and powers of the holders of Common Stock,
and shall be entitled to notice of any stockholders' meeting in accordance with
the bylaws of the Corporation (as in effect at the time in question) and
applicable law, and shall be entitled to vote, together with the holders of
Common Stock, with respect to any question upon which holders of Common Stock
have the right to vote, except as may be otherwise provided by applicable law.
Except as otherwise expressly provided herein or as required by law, the holders
of Preferred Stock and the holders of Common Stock shall vote together and not
as separate classes.

        5. CONVERSION RIGHTS. The outstanding shares of Preferred Stock shall be
convertible into Common Stock as follows:

                5.1 Optional Conversion.

                        (a) At the option of the holder thereof, each share of
Preferred Stock shall be convertible, at any time or from time to time prior to
the close of business on the business day before any date fixed for redemption
of such share, into fully paid and nonassessable shares of Common Stock as
provided herein.

                        (b) Each holder of Preferred Stock who elects to convert
the same into shares of Common Stock shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or any
transfer agent for the Preferred Stock or Common Stock, and



                                       6
   111

shall give written notice to the Corporation at such office that such holder
elects to convert the same and shall state therein the number of shares of
Preferred Stock being converted. Thereupon the Corporation shall promptly issue
and deliver at such office to such holder a certificate or certificates for the
number of shares of Common Stock to which such holder is entitled upon such
conversion. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the certificate or
certificates representing the shares of Preferred Stock to be converted, and the
person entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder of such shares
of Common Stock on such date. If a conversion election under this subsection 5.1
is made in connection with an underwritten offering of the Corporation's
securities pursuant to the Securities Act of 1933, as amended, (which
underwritten offering does not cause an automatic conversion pursuant to
subsection 5.2 to take place) the conversion may, at the option of the holder
tendering shares of Preferred Stock for conversion, be conditioned upon the
closing with the underwriters of the sale of the Corporation's securities
pursuant to such offering, in which event the holders making such elections who
are entitled to receive Common Stock upon conversion of their Preferred Stock
shall not be deemed to have converted such shares of Preferred Stock until
immediately prior to the closing of such sale of the Corporation's securities in
the offering.

                5.2 Automatic Conversion.

                        (a) Each share of Preferred Stock shall automatically be
converted into fully paid and nonassessable shares of Common Stock, as provided
herein: (i) immediately prior to the closing of a firm commitment underwritten
public offering pursuant to an effective registration statement filed under the
Securities Act of 1933, as amended, covering the offer and sale of Common Stock
for the account of the Corporation in which the aggregate public offering price
(before deduction of underwriters' discounts and commissions) equals or exceeds
Twenty-Five Million Dollars ($25,000,000) and the public offering price per
share of which equals or exceeds Five Dollars ($5.00) per share before deduction
of underwriters' discounts and commissions (such price per share of Common Stock
to be appropriately adjusted to reflect Common Stock Events (as defined in
subsection 5.4); or (ii) upon the Corporation's receipt of the written consent
of the holders of not less than sixty-six percent (66%) of the then outstanding
shares of Preferred Stock to the conversion of all then outstanding Preferred
Stock under this Section 5.

                        (b) Upon the occurrence of an event specified in
subparagraph 5.2(a) (i) or (ii) above, the outstanding shares of Preferred Stock
shall be converted into Common Stock automatically without the need for any
further action by the holders of such shares and whether or not the certificates
representing such shares are surrendered to the Corporation or its transfer
agent; provided, however, that the Corporation shall not be obligated to issue
certificates evidencing the shares of Common Stock issuable upon such conversion
unless the certificates evidencing such shares of Preferred Stock are either
delivered to the Corporation or its transfer agent as provided below, or the
holder notifies the Corporation or its transfer agent that such certificates
have been lost, stolen or destroyed and executes an agreement satisfactory to
the Corporation to indemnify the Corporation from any loss incurred by it in
connection with such



                                       7
   112

certificates. Upon the occurrence of such automatic conversion of the Preferred
Stock, the holders of Preferred Stock shall surrender the certificates
representing such shares at the office of the Corporation or any transfer agent
for the Preferred Stock or Common Stock. Thereupon, there shall be issued and
delivered to such holder promptly at such office and in its name as shown on
such surrendered certificate or certificates, a certificate or certificates for
the number of shares of Common Stock into which the shares of Preferred Stock
surrendered were convertible on the date on which such automatic conversion
occurred.

                5.3 Conversion Price. Each share of Preferred Stock shall be
convertible in accordance with subsection 5.1 or subsection 5.2 above into the
number of shares of Common Stock which results from dividing the Original Issue
Price for such series of Preferred Stock by the conversion price for such series
of Preferred Stock that is in effect at the time of conversion (the "CONVERSION
PRICE"). The initial Conversion Price for each such series of Preferred Stock,
other than the Series C-3 Preferred Stock, shall be the Original Issue Price for
such series of Preferred Stock, and the initial Conversion Price for the Series
C-3 Preferred Stock shall be Three Dollars Twenty-Five Cents ($3.25). The
Conversion Price of each series of the Preferred Stock shall be subject to
adjustment from time to time as provided below. Following each adjustment of the
Conversion Price, such adjusted Conversion Price shall remain in effect until a
further adjustment of such Conversion Price hereunder.

                5.4 Adjustment Upon Common Stock Event. Upon the happening of a
Common Stock Event (as hereinafter defined), the Conversion Price of each series
of Preferred Stock shall, simultaneously with the happening of such Common Stock
Event, be adjusted by multiplying the Conversion Price of such series of
Preferred Stock in effect immediately prior to such Common Stock Event by a
fraction, (i) the numerator of which shall be the number of shares of Common
Stock issued and outstanding immediately prior to such Common Stock Event, and
(ii) the denominator of which shall be the number of shares of Common Stock
issued and outstanding immediately after such Common Stock Event, and the
product so obtained shall thereafter be the Conversion Price for such series of
Preferred Stock. The Conversion Price for each series of Preferred Stock shall
be readjusted in the same manner upon the happening of each subsequent Common
Stock Event. As used herein, the term the "COMMON STOCK EVENT" shall mean at any
time or from time to time after the Original Issue Date, (i) the issue by the
Corporation of additional shares of Common Stock as a dividend or other
distribution on outstanding Common Stock, (ii) a subdivision of the outstanding
shares of Common Stock into a greater number of shares of Common Stock, or (iii)
a combination of the outstanding shares of Common Stock into a smaller number of
shares of Common Stock.

                5.5 Adjustments for Other Dividends and Distributions. If at any
time or from time to time after the Original Issue Date the Corporation pays a
dividend or makes another distribution to the holders of the Common Stock
payable in securities of the Corporation, other than an event constituting a
Common Stock Event, or in other property not provided for elsewhere in this
Section 5, then in each such event provision shall be made so that the holders
of the Preferred Stock shall receive upon conversion thereof, in addition to the
number of shares of Common Stock receivable upon conversion thereof, the amount
of securities of the Corporation or other property which they would have
received had their Preferred Stock been converted into



                                       8
   113

Common Stock on the date of such event (or such record date, as applicable) and
had they thereafter, during the period from the date of such event (or such
record date, as applicable) to and including the conversion date, retained such
securities or other property receivable by them as aforesaid during such period,
subject to all other adjustments called for during such period under this
Section 5 with respect to the rights of the holders of the Preferred Stock or
with respect to such other securities or other property by its terms.

                5.6 Adjustment for Reclassification, Exchange and Substitution.
If at any time or from time to time after the Original Issue Date the Common
Stock issuable upon the conversion of the Preferred Stock is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than by a Common Stock
Event or a stock dividend, reorganization, merger, consolidation or sale of
assets provided for elsewhere in this Section 5), then in any such event each
holder of Preferred Stock shall have the right thereafter to convert such stock
into the kind and amount of stock and other securities and property receivable
upon such recapitalization, reclassification or other change by holders of the
number of shares of Common Stock into which such shares of Preferred Stock could
have been converted immediately prior to such recapitalization, reclassification
or change, all subject to further adjustment as provided herein or with respect
to such other securities or property by the terms thereof.

                5.7 Reorganizations, Mergers and Consolidations. If at any time
or from time to time after the Original Issue Date there is a reorganization of
the Corporation (other than a recapitalization, subdivision, combination,
reclassification or exchange of shares provided for elsewhere in this Section 5)
or a merger or consolidation of the Corporation with or into another corporation
(except an event which is governed under subsection 3.3), then, as a part of
such reorganization, merger or consolidation, provision shall be made so that
the holders of the Preferred Stock thereafter shall be entitled to receive, upon
conversion of the Preferred Stock, the number of shares of stock or other
securities or property of the Corporation, or of such successor corporation
resulting from such reorganization, merger or consolidation, to which a holder
of Common Stock deliverable upon conversion would have been entitled on such
reorganization, merger or consolidation. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 5
with respect to the rights of the holders of the Preferred Stock after the
reorganization, merger or consolidation to the end that the provisions of this
Section 5 (including adjustment of the Conversion Price then in effect and
number of shares issuable upon conversion of the Preferred Stock) shall be
applicable after that event and be as nearly equivalent to the provisions hereof
as may be practicable. This subsection 5.7 shall similarly apply to successive
reorganizations, mergers and consolidations.

                5.8 Sale of Shares Below Conversion Price.

                        (a) Adjustment Formula. If at any time or from time to
time after the Original Issue Date the Corporation issues or sells, or is deemed
by the provisions of this subsection 5.8 to have issued or sold, Additional
Shares of Common Stock (as hereinafter defined), otherwise than in connection
with a Common Stock Event as provided in subsection 5.4, a dividend or
distribution as provided in subsection 5.5, a recapitalization, reclassification
or



                                       9
   114

other change as provided in subsection 5.6, or a reorganization, merger or
consolidation as provided in subsection 5.7, for an Effective Price (as
hereinafter defined) that is less than the Conversion Price for a series of
Preferred Stock in effect immediately prior to such issue or sale (or deemed
issue or sale), then, and in each such case, the Conversion Price for such
series of Preferred Stock shall be reduced, as of the close of business on the
date of such issue or sale, to the price obtained by multiplying such Conversion
Price by a fraction:

                                (i) The numerator of which shall be the sum of
(A) the number of Common Stock Equivalents Outstanding (as hereinafter defined)
immediately prior to such issue or sale of Additional Shares of Common Stock
plus (B) the quotient obtained by dividing the Aggregate Consideration Received
(as hereinafter defined) by the Corporation for the total number of Additional
Shares of Common Stock so issued or sold (or deemed so issued and sold) by the
Conversion Price for such series of Preferred Stock in effect immediately prior
to such issue or sale; and

                                (ii) The denominator of which shall be the sum
of (A) the number of Common Stock Equivalents Outstanding immediately prior to
such issue or sale plus (B) the number of Additional Shares of Common Stock so
issued or sold (or deemed so issued and sold).

                        (b) Certain Definitions. For the purpose of making any
adjustment required under this subsection 5.8:

                                (i) The "ADDITIONAL SHARES OF COMMON STOCK"
shall mean all shares of Common Stock issued (including such shares that are
deemed to have been issued pursuant to Section 5.8(c)) by the Corporation,
whether or not subsequently reacquired or retired by the Corporation, other
than:

                                        (A) shares of Common Stock issued or
issuable upon conversion of the outstanding shares of the Preferred Stock;

                                        (B) any shares of Common Stock or
Preferred Stock (and/or options, warrants or rights therefor) granted or issued
hereafter to employees, officers, directors, contractors, consultants or
advisers to, the Corporation or any Subsidiary pursuant to incentive agreements,
stock purchase or stock option plans, stock bonuses or awards, warrants,
contracts or other arrangements that are approved by the Board of Directors;

                                        (C) any shares of the Corporation's
Common Stock or Preferred Stock (and/or options, warrants or rights therefor)
issued or issuable to parties that are (i) providing the Corporation with
equipment leases, real property leases, loans, credit lines, guaranties of
indebtedness or similar transactions; (ii) providers of goods and services; or
(iii) providers or developers of content or technology, or strategic or
commercial partners of the Corporation; provided that such arrangements, in each
case, are approved by the Board of Directors and are for primarily non-equity
financing purposes;



                                       10
   115

                                        (D) shares of Common Stock or Preferred
Stock (and/or options, warrants or rights therefor) issued pursuant to the
acquisition of another corporation or entity by the Corporation by
consolidation, merger, purchase of all or substantially all of the assets, or
other reorganization in which the Corporation acquires, in a single transaction
or series of related transactions, all or substantially all of the assets of
such other corporation or entity or a division or business unit of such
corporation or entity or fifty percent (50%) or more of the voting power of such
other corporation or entity or fifty percent (50%) or more of the equity
ownership of such other entity;

                                        (E) shares of Common Stock issued
pursuant to a transaction described in Section 5.4 hereof; and

                                        (F) shares of Common Stock issued or
issuable in a public offering prior to or in connection with which all
outstanding shares of Preferred Stock will be converted into Common Stock.

                                (ii) The "AGGREGATE CONSIDERATION RECEIVED" by
the Corporation for any issue or sale (or deemed issue or sale) of securities
shall (A) to the extent it consists of cash, be computed at the gross amount of
cash received by the Corporation before deduction of any underwriting or similar
commissions, compensation or concessions paid or allowed by the Corporation in
connection with such issue or sale and without deduction of any expenses payable
by the Corporation; (B) to the extent it consists of property other than cash,
be computed at the fair value of that property as determined in good faith by
the Board; and (C) if Additional Shares of Common Stock, Convertible Securities
or Rights or Options to purchase either Additional Shares of Common Stock or
Convertible Securities are issued or sold together with other stock or
securities or other assets of the Corporation for a consideration which covers
both, be computed as the portion of the consideration so received that may be
reasonably determined in good faith by the Board to be allocable to such
Additional Shares of Common Stock, Convertible Securities or Rights or Options.

                                (iii) The "COMMON STOCK EQUIVALENTS OUTSTANDING"
shall mean the number of shares of Common Stock that is equal to the sum of (A)
all shares of Common Stock of the Corporation that are outstanding at the time
in question, plus (B) all shares of Common Stock of the Corporation issuable
upon conversion of all shares of Preferred Stock or other Convertible Securities
that are outstanding at the time in question, plus (C) all shares of Common
Stock of the Corporation that are issuable upon the exercise of Rights or
Options (excluding any shares of Common Stock excluded from the definition of
"Additional Shares of Common Stock" pursuant to subsection 5.8(b)(i)(B), after
the Original Issue Date) that are outstanding at the time in question assuming
the full conversion or exchange into Common Stock of all such Rights or Options
that are Rights or Options to purchase or acquire Convertible Securities into or
for Common Stock.

                                (iv) The "CONVERTIBLE SECURITIES" shall mean
stock or other securities convertible into, or exchangeable for, shares of
Common Stock.



                                       11
   116

                                (v) The "EFFECTIVE PRICE" of Additional Shares
of Common Stock shall mean the quotient determined by dividing the total number
of Additional Shares of Common Stock issued or sold, or deemed to have been
issued or sold, by the Corporation under this subsection 5.8, into the Aggregate
Consideration Received, or deemed to have been received, by the Corporation
under this subsection 5.8, for the issue of such Additional Shares of Common
Stock; and

                                (vi) The "RIGHTS OR OPTIONS" shall mean
warrants, options or other rights to purchase or acquire shares of Common Stock
or Convertible Securities.

                        (c) Deemed Issuances. For the purpose of making any
adjustment to the Conversion Price of any series of Preferred Stock required
under this subsection 5.8, if the Corporation issues or sells any Rights or
Options or Convertible Securities and if the Effective Price of the shares of
Common Stock issuable upon exercise of such Rights or Options and/or the
conversion or exchange of Convertible Securities (computed without reference to
any additional or similar protective or antidilution clauses) is less than the
Conversion Price then in effect for a series of Preferred Stock, then the
Corporation shall be deemed to have issued, at the time of the issuance of such
Rights, Options or Convertible Securities, that number of Additional Shares of
Common Stock that is equal to the maximum number of shares of Common Stock
issuable upon exercise or conversion of such Rights, Options or Convertible
Securities upon their issuance and to have received, as the Aggregate
Consideration Received for the issuance of such shares, an amount equal to the
total amount of the consideration, if any, received by the Corporation for the
issuance of such Rights or Options or Convertible Securities, plus, in the case
of such Rights or Options, the minimum amounts of consideration, if any, payable
to the Corporation upon the exercise in full of such Rights or Options, plus, in
the case of Convertible Securities, the minimum amounts of consideration, if
any, payable to the Corporation (other than by cancellation of liabilities or
obligations evidenced by such Convertible Securities) upon the conversion or
exchange thereof; provided that:

                                (i) if the minimum amounts of such consideration
cannot be ascertained, but are a function of antidilution or similar protective
clauses, then the Corporation shall be deemed to have received the minimum
amounts of consideration without reference to such clauses;

                                (ii) if the minimum amount of consideration
payable to the Corporation upon the exercise of Rights or Options or the
conversion or exchange of Convertible Securities is reduced over time or upon
the occurrence or non-occurrence of specified events other than by reason of
antidilution or similar protective adjustments, then the Effective Price shall
be recalculated using the figure to which such minimum amount of consideration
is reduced; and

                                (iii) if the minimum amount of consideration
payable to the Corporation upon the exercise of such Rights or Options or the
conversion or exchange of Convertible Securities is subsequently increased, then
the Effective Price shall again be recalculated using the increased minimum
amount of consideration payable to the Corporation



                                       12
   117

upon the exercise of such Rights or Options or the conversion or exchange of
such Convertible Securities.

No further adjustment of the Conversion Price, adjusted upon the issuance of
such Rights or Options or Convertible Securities, shall be made as a result of
the actual issuance of shares of Common Stock on the exercise of any such Rights
or Options or the conversion or exchange of any such Convertible Securities. If
any such Rights or Options or the conversion rights represented by any such
Convertible Securities shall expire without having been fully exercised, then
the Conversion Price as adjusted upon the issuance of such Rights or Options or
Convertible Securities shall be readjusted to the Conversion Price which would
have been in effect had an adjustment been made on the basis that the only
shares of Common Stock so issued were the shares of Common Stock, if any, that
were actually issued or sold on the exercise of such Rights or Options or rights
of conversion or exchange of such Convertible Securities, and such shares of
Common Stock, if any, were issued or sold for the consideration actually
received by the Corporation upon such exercise, plus the consideration, if any,
actually received by the Corporation for the granting of all such Rights or
Options, whether or not exercised, plus the consideration received for issuing
or selling all such Convertible Securities actually converted or exchanged, plus
the consideration, if any, actually received by the Corporation (other than by
cancellation of liabilities or obligations evidenced by such Convertible
Securities) on the conversion or exchange of such Convertible Securities,
provided that such readjustment shall not apply to prior conversions of
Preferred Stock.

                5.9 Certificate of Adjustment. In each case of an adjustment or
readjustment of the Conversion Price for a series of Preferred Stock, the
Corporation, at its expense, shall cause its Chief Financial Officer to compute
such adjustment or readjustment in accordance with the provisions hereof and
prepare a certificate showing such adjustment or readjustment, and shall mail
such certificate, by first class mail, postage prepaid, to each registered
holder of the Preferred Stock at the holder's address as shown in the
Corporation's books.

                5.10 Fractional Shares. No fractional shares of Common Stock
shall be issued upon any conversion of Preferred Stock. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall pay the holder cash equal to the product of such fraction
multiplied by the Common Stock's fair market value as determined in good faith
by the Board as of the date of conversion.

                5.11 Reservation of Stock Issuable Upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Preferred Stock, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of the Preferred Stock; and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose.



                                       13
   118

                5.12 Notices. Any notice required by the provisions of this
Certificate of Incorporation to be given to the holders of shares of the
Preferred Stock shall be deemed given upon the earlier of actual receipt or
deposit in the United States mail, by certified or registered mail, return
receipt requested, postage prepaid, or delivery by a recognized express courier,
fees prepaid, addressed to each holder of record at the address of such holder
appearing on the books of the Corporation.

                5.13 No Impairment. The Corporation shall not avoid or seek to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation, but shall at all times in good faith
assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the conversion rights of the holders of the
Preferred Stock against impairment.

        6. RESTRICTIONS AND LIMITATIONS.

                6.1 Series A Protective Provisions. So long as any shares of
Series A Preferred Stock remain outstanding, the Corporation shall not, without
the approval, by vote or written consent, of the holders of a majority of the
Series A Preferred Stock then outstanding, voting as a separate series:

                        (a) amend its Certificate of Incorporation in any manner
that would alter or change the rights, preferences, privileges or restrictions
of such series of Preferred Stock;

                        (b) authorize or issue any other equity security,
including any other security convertible into or exercisable for any equity

any manner that materially and adversely affects the rights of such series of
Preferred Stock.

                6.2 Series B Protective Provisions. So long as any shares of
Series B Preferred Stock remain outstanding, the Corporation shall not, without

Series B Preferred Stock then outstanding, voting as a separate series:

                        (a) amend its Certificate of Incorporation in any manner
that would alter or change the rights, preferences, privileges or restrictions
of such series of Preferred Stock;

                        (b) authorize or issue any other equity security,
including any other security convertible into or exercisable for any equity

any manner that materially and adversely affects the rights of such series of
Preferred Stock.

                6.3 Series C Protective Provisions. So long as any shares of

the approval, by vote or written consent, of the holders of a majority of the
Series C Preferred Stock (with the Series C-1 Preferred Stock, Series C-2
Preferred Stock and Series C-3 Preferred Stock treated as a single series) then
outstanding, voting as a separate series on an as-converted to Common Stock
basis; provided, however, that in the event of an amendment contemplated by
Section 6.3(d) below that materially and adversely affects the rights of the
Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred
Stock in a manner different from any other such Series C Preferred Stock, such
amendment shall require the prior approval of the holders of a majority of the
Series C-1 Preferred Stock, Series C-2 Preferred Stock, Series C-3 Preferred
Stock, as the case may be, voting separately:

                        (a) amend its Certificate of Incorporation in any manner

of the Series C Preferred Stock;

                        (b) authorize or issue any other equity security,
including any other security convertible into or exercisable for any equity
security having rights or preferences senior to or being on a parity with the
Series C Preferred Stock as to dividend rights or liquidation preferences;

                        (c) reclassify any outstanding shares of securities of

or on a parity with the Series C Preferred Stock; or

                        (d) amend its Certificate of Incorporation or Bylaws in
any manner that materially and adversely affects the rights of the Series C

                6.4 Class Protective Provisions. So long as any shares of

approval, by vote or written consent, of the holders of a majority of the
Preferred Stock then outstanding, voting as a single class on an as-converted to
Common Stock basis (and not as separate series):

                        (a) effect the acquisition of the Corporation by another
entity by means of any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation) that results in

the Corporation;



                                       15
   120

                        (b) sell, convey of otherwise dispose of all or

                7.1 No Reissuance of Preferred Stock. No share or shares of

                7.2 Preemptive Rights. No stockholder of the Corporation shall
have a right to purchase shares of capital stock of the Corporation sold or

                                   ARTICLE VI

        The Board of Directors of the Corporation shall have the power to adopt,

elimination or limitation of the liability of a director, then the liability of
a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.

        Neither any amendment nor repeal of this Article VIII, nor the adoption

                                                                       EXHIBIT G

             FIRST AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT


        This FIRST AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT (this
"AGREEMENT") is made and entered into as of January ___, 2001 by and among
Shockwave.com, Inc., a Delaware corporation (the "COMPANY"), Macromedia, Inc., a
Delaware corporation ("MACROMEDIA"), the persons and entities listed on Exhibit
A attached hereto (the "SERIES B PURCHASERS" and, together with Macromedia, the
"PRIOR INVESTORS"), and the persons and entities listed on Exhibit B attached
hereto (the "ATOM SHAREHOLDERS" and, together with the Prior Investors, the
"INVESTORS").

        A. In connection with the formation of the Company, Macromedia
contributed certain assets to the Company and entered into certain agreements
with the Company and in exchange therefor has received shares of the Company's
Series A Preferred Stock (the "SERIES A STOCK") issued by the Company to
Macromedia pursuant to that certain Formation Agreement, dated as of December 1,
1999, by and between the Company and Macromedia (the "FORMATION AGREEMENT"),
that certain Asset License Agreement of even date therewith (the "ASSET
LICENSING AGREEMENT"), that certain IT Services Agreement of even date
therewith, that certain Corporate Services Agreement of even date therewith and
other ancillary agreements as contemplated by the Formation Agreement
(collectively the "MACROMEDIA AGREEMENTS").

        B. As part of and in connection with the transactions contemplated by
the Macromedia Agreements, the Series B Purchasers purchased from the Company
shares of the Company's Series B Preferred Stock (the "SERIES B STOCK") issued
by the Company to such Series B Purchasers pursuant to that certain Series B
Preferred Stock Purchase Agreement, dated as of December 1, 1999, by and among
the Company, the Series B Purchasers and, for the purpose only of Sections 4, 6
and 9, Macromedia (the "SERIES B AGREEMENT").

        C. The Company has issued common stock purchase warrants to acquire
shares of Common Stock (the "WARRANTS") to content and service providers
described on Exhibit C to this Agreement (the "WARRANT HOLDERS") and shares of
Common Stock (the "SHARES") to Macromedia subject to a subscription agreement
(the "SUBSCRIPTION AGREEMENT"), and desires to give registration rights with
regard to the Shares and the shares of Common Stock issuable upon exercise of
the Warrants; and

        D. The Prior Investors have been granted certain information,
registration rights and/or rights of first refusal under an Investors' Rights
Agreement, dated as of December 1, 1999, by and between the Prior Holders and
the Company, as amended by Amendment No. 1 to Investors' Rights Agreement dated
as of January 14, 2000 and Amendment No. 2 to Investors' Rights Agreement dated
as of April 27, 2000 (the "PRIOR RIGHTS AGREEMENT").

        E. The Company and Atom Corporation, a Washington corporation ("ATOM"),
entered into an Agreement and Plan of Reorganization dated as of December 14,
2000 (the "MERGER AGREEMENT"), which provides (subject to the conditions set
forth therein) for the merger of Atom with and into the Company (the "MERGER")
with the Company to survive the Merger. Upon the effectiveness of the Merger,
the outstanding shares of Atom Common Stock and Atom


   122

Preferred Stock will be converted into the right to receive Shockwave Common
Stock and Shockwave Series C Preferred Stock (the "SERIES C STOCK" and, together
with the Series A Stock and the Series B Stock, the "PREFERRED STOCK"), and
outstanding Atom Options (as defined in the Merger Agreement) and Atom Warrants
(as defined in the Merger Agreement) to purchase shares of Atom Common Stock and
Atom Preferred Stock will be converted into Shockwave Options (as defined in the
Merger Agreement) and Shockwave Warrants (as defined in the Merger Agreement),
all as more particularly set forth in the Merger Agreement. The Merger Agreement
provides that, as a condition to Atom's obligations under the Merger Agreement,
the Company will enter into this Agreement and the Atom Shareholders will be
granted the rights set forth herein.

        F. The Company and the Prior Investors desire to enter into this
Agreement in order to amend, restate and replace their rights and obligations
under the Prior Rights Agreement with the rights and obligations set forth in
this Agreement. Section 4.2 of the Prior Rights Agreement provides that the
Prior Rights Agreement may be amended by the written consent of the holders of
sixty-six percent (66%) of all the Registrable Securities (as defined in the
Prior Rights Agreement), and the undersigned parties to this Agreement hold
sixty-six percent (66%) or more of the Registrable Securities.

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual promises hereinafter set forth, the parties hereto agree as follows:

        1.      INFORMATION RIGHTS.

               1.1 Financial Information. The Company covenants and agrees that,
commencing on the date of this Agreement, for so long as any Investor holds at
least 300,000 shares of Preferred Stock and/or the equivalent number (on an
as-converted basis) of shares of Common Stock issued upon the conversion of such
shares of Preferred Stock ("CONVERSION STOCK"), the Company will:

                    (a) Annual Reports. Furnish to such Investor, as soon as
practicable and in any event within one hundred twenty (120) days after the end
of each fiscal year of the Company, a consolidated Balance Sheet as of the end
of such fiscal year, a consolidated Statement of Income and a consolidated
Statement of Cash Flows of the Company and its subsidiaries for such year,
setting forth in each case in comparative form the figures from the Company's
previous fiscal year (if any), all prepared in accordance with generally
accepted accounting principles and practices and audited by nationally
recognized independent certified public accountants; and

                    (b) Quarterly Reports. Furnish to such Investor as soon as
practicable, and in any case within sixty (60) days after the end of each fiscal
quarter of the Company (except the last quarter of the Company's fiscal year),
quarterly unaudited financial statements, including an unaudited Balance Sheet,
an unaudited Statement of Income and an unaudited Statement of Cash Flows.

   123

                    (c) Reporting with Macromedia. So long as the Company
consolidates its financial statements with Macromedia and Macromedia is subject
to the reporting requirements of the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), the Company's obligation to deliver financial information
in this Section 1.1 shall be satisfied, as to Macromedia, by filing of
Macromedia's periodic reports under the Exchange Act and, as to Investors other
than Macromedia entitled to receive such reports under this Section 1.1, by
delivery to such Investors of the publicly filed reports of Macromedia. If
Macromedia ceases to consolidate its financial statements with those of the
Company, the Company shall prepare and deliver to investors entitled to receive
such reports under this Section 1.1, financial statements as provided therein.

                    (d) Confidentiality. Unless such information is otherwise
made generally available to the public through filings with the Securities and
Exchange Commission (the "COMMISSION") or otherwise, each Investor agrees to
hold all information received pursuant to this Section 1.1 in confidence and not
to use or disclose any of such information to any third party, except to the
extent such information may be made publicly available by the Company.

               1.2 Inspection Rights. The Company shall permit each Investor
holding at least 300,000 shares of Preferred Stock and/or the equivalent number
(on an as-converted basis) of shares of Conversion Stock, or any combination
thereof, at such Investor's expense, to visit and inspect the Company's
properties, to examine its books of account and records and to discuss the
Company's affairs, finances and accounts with its officers, all at such
reasonable times as may be requested by such Investor. Each Investor agrees to
hold all information received from such inspections in confidence, and not to
use or disclose any of such information to any third party, except to the extent
such information may be made publicly available by the Company.

               1.3 Termination of Information Rights. The Company's obligations
under Sections 1.1 and 1.2 above will terminate upon the earliest to occur of
the following: (i) the initial closing of the Company's initial public offering
of Common Stock pursuant to an effective registration statement filed under the
U.S. Securities Act of 1933, as amended (the "SECURITIES ACT"); (ii) the
effective time of a merger or other acquisition of the Company in which the
Company is not the surviving corporation or (iii) the time at which the Company
itself becomes subject to the reporting requirements of the Exchange Act (other
than as an entity consolidated for reporting purposes with Macromedia).

        2.      REGISTRATION RIGHTS.

                2.1     Definitions. For purposes of this Section 2:

                    (a) Registration. The terms "REGISTER," "REGISTRATION" and
"REGISTERED" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act, and the
declaration or ordering of effectiveness of such registration statement.

                    (b) Registrable Securities. The term "REGISTRABLE
SECURITIES" means: (1) all the shares of Common Stock issued or issuable upon
the conversion of any shares of Series A Stock issued under the Formation
Agreement; (2) all shares of Common Stock issued

   124

under the Formation Agreement; (3) all shares of Common Stock issued or issuable

STOCK"); (5) all shares of Common Stock issued to Macromedia under the
Subscription Agreement; (6) all shares of Common Stock issued or issuable upon
the conversion of any shares of Series C Stock issued under the Merger
Agreement; and (7) all shares of Common Stock issued as (or issuable upon the
conversion or exercise of any warrant, right or other security which is issued
as) a dividend or other distribution with respect to, or in exchange for or in
replacement of, all such shares of Common Stock described in clause (1), (2),
(3), (4), (5) or (6) of this subsection (b); excluding in all cases, however,
any Registrable Securities sold by a person in a transaction in which rights
under this Section 2 are not assigned in accordance with this Agreement or any
Registrable Securities sold to the public or sold pursuant to Rule 144
promulgated under the Securities Act.

                    (c) Registrable Securities Then Outstanding. The number of
shares of "REGISTRABLE SECURITIES THEN OUTSTANDING" shall mean the number of
shares of Common Stock which are Registrable Securities and (1) are then issued
and outstanding or (2) are then issuable pursuant to the exercise or conversion
of then outstanding and then exercisable options, warrants or convertible
securities.

                    (d) Holder. For purposes of this Section 2 and Sections 3
and 4 hereof, the term "HOLDER" means any person owning of record Registrable
Securities that have not been sold to the public or pursuant to Rule 144
promulgated under the Securities Act or any assignee of record of such
Registrable Securities to whom rights under such Sections have been duly
assigned in accordance with this Agreement; provided, however, that for purposes
of this Agreement, a record holder of shares of Series A Stock, Series B Stock
or Series C Stock convertible into such Registrable Securities and a holder of
Warrants exercisable for Registrable Securities shall be deemed to be the Holder
of such Registrable Securities; provided further, that a holder of Warrant Stock
with respect to such Warrant Stock and a holder of Macromedia with respect to
such Common Stock shall not be a Holder for purposes of Sections 2.2 or 3 of
this Agreement; and provided, further, that the Company shall in no event be
obligated to register shares of Preferred Stock or Warrants, and Holders of
Registrable Securities will not be required to convert their shares of Series A
Stock, Series B Stock, or Series C Stock into Common Stock, and the holders of
Warrants will not be required to exercise these securities for stock, in order
to exercise the registration rights granted hereunder until immediately before
the closing of the offering to which the registration relates.

                    (e) Form S-3. The term "FORM S-3" means such form under the
Securities Act as is in effect on the date hereof or any successor registration
form under the Securities Act subsequently adopted by the SEC which permits
inclusion or incorporation of substantial information by reference to other
documents filed by the Company with the SEC.

                    (f) SEC. The term "SEC" or "COMMISSION" means the U.S.
Securities and Exchange Commission.

   125

               2.2 Demand Registration.

                    (a) Request by Holders. If the Company shall receive at any
time after the earlier of (i) November 25, 2003 or (ii) six (6) months after the
effective date of the Company's initial public offering of its securities
pursuant to a registration filed under the Securities Act, a written request
from the Holders of at least a majority of the Registrable Securities then
outstanding that the Company file a registration statement under the Securities
Act covering the registration of Registrable Securities pursuant to this Section
2.2, then the Company shall, within twenty (20) days after the receipt of such
written request, give written notice of such request ("REQUEST NOTICE") to all
Holders, and effect, as soon as practicable, the registration under the
Securities Act of all Registrable Securities which Holders request to be
registered and included in such registration by written notice given by such
Holders to the Company within twenty (20) days after receipt of the Request
Notice, subject only to the limitations of this Section 2; provided that the
Registrable Securities requested by all Holders to be registered pursuant to
such request must either (i) be at least twenty-five percent (25%) of all
Registrable Securities then outstanding or (ii) have an anticipated aggregate
public offering price (before any underwriting discounts and commissions) of not
less than $25,000,000. The Company shall not be obligated to effect a
registration under this Section 2.2 during the six-month period after the
effective date of the Company's initial public offering of its securities as set
forth above.

                    (b) Underwriting. If the Holders initiating the registration
request under this Section 2.2 ("INITIATING HOLDERS") intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
then they shall so advise the Company as a part of their request made pursuant
to this Section 2.2 and the Company shall include such information in the
written notice referred to in Section 2.2(a). In such event, the right of any
Holder to include his Registrable Securities in such registration shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting (unless
otherwise mutually agreed by a majority in interest of the Initiating Holders
and such Holder) to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting by the Company and a majority in
interest of the Initiating Holders. Notwithstanding any other provision of this
Section 2.2, if the underwriter(s) advise(s) the Company in writing that
marketing factors require a limitation of the number of securities to be
underwritten then the Company shall so advise all Holders of Registrable
Securities that would otherwise be registered and underwritten pursuant hereto,
and the number of Registrable Securities that may be included in the
underwriting shall be reduced as required by the underwriter(s) and allocated
among the Holders of Registrable Securities on a pro rata basis according to the
number of Registrable Securities then outstanding held by each Holder requesting
registration (including the Initiating Holders); provided, however, that the
number of shares of Registrable Securities to be included in such underwriting
and registration shall not be reduced unless all other securities of the Company
are first entirely excluded from the underwriting and registration. Any
Registrable Securities excluded and withdrawn from such underwriting shall be
withdrawn from the registration.

   126

                    (c) Maximum Number of Demand Registrations. The Company is
obligated to effect only two (2) such registrations pursuant to this Section
2.2.

                    (d) Deferral. Notwithstanding the foregoing, if the Company
shall furnish to Holders requesting the filing of a registration statement
pursuant to this Section 2.2, a certificate signed by the President or Chief
Executive Officer of the Company stating that in the good faith judgment of the
Board of Directors of the Company, it would be seriously detrimental to the
Company and its shareholders for such registration statement to be filed and it
is therefore essential to defer the filing of such registration statement, then
the Company shall have the right to defer such filing for a period of not more
than one hundred twenty (120) days after receipt of the request of the
Initiating Holders; provided, however, that the Company may not utilize this
right more than once in any twelve (12) month period.

                    (e) Expenses. All expenses incurred in connection with a
registration pursuant to this Section 2.2, including without limitation all
federal and "blue sky" registration and qualification fees, printers' and
accounting fees, fees and disbursements of counsel for the Company, and the
reasonable fees and disbursements of one counsel for the selling Holders (but
excluding underwriters' discounts and commissions) shall be borne by the
Company. Each Holder participating in a registration pursuant to this Section
2.2 shall bear such Holder's proportionate share (based on the total number of
shares sold in such registration other than for the account of the Company) of
all discounts, commissions or other amounts payable to underwriters or brokers
in connection with such offering. Notwithstanding the foregoing, the Company
shall not be required to pay for any expenses of any registration proceeding
begun pursuant to this Section 2.2 if the registration request is subsequently
withdrawn at the request of the Holders of a majority of the Registrable
Securities to be registered, unless the Holders of a majority of the Registrable
Securities then outstanding agree to forfeit their right to one (1) demand
registration pursuant to this Section 2.2 (in which case such right shall be
forfeited by all Holders of Registrable Securities); provided, further, however,
that if at the time of such withdrawal, the Holders have learned of a material
adverse change in the condition, business, or prospects of the Company not known
to the Holders at the time of their request for such registration and have
withdrawn their request for registration with reasonable promptness after
learning of such material adverse change, then the Holders shall not be required
to pay any of such expenses and shall retain their rights pursuant to this
Section 2.2.

               2.3 Piggyback Registrations. The Company shall notify all Holders
of Registrable Securities in writing at least thirty (30) days prior to filing
any registration statement under the Securities Act for purposes of effecting a
public offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to any registration
under Section 2.2 or Section 2.4 of this Agreement or to any employee benefit
plan or a corporate reorganization) and will afford each such Holder an
opportunity to include in such registration statement all or any part of the
Registrable Securities then held by such Holder. Each Holder desiring to include
in any such registration statement all or any part of the Registrable Securities
held by such Holder shall, within twenty (20) days after receipt of the
above-described notice from the Company, so notify the Company in writing, and
in such notice shall inform the
   127
Company of the number of Registrable Securities such Holder wishes to include in
such registration statement. If a Holder decides not to include all of its
Registrable Securities in any registration statement thereafter filed by the
Company, such Holder shall nevertheless continue to have the right to include
any Registrable Securities in any subsequent registration statement or
registration statements as may be filed by the Company with respect to offerings
of its securities, all upon the terms and conditions set forth herein.

                    (a) Underwriting. If a registration statement under which
the Company gives notice under this Section 2.3 is for an underwritten offering,
then the Company shall so advise the Holders of Registrable Securities. In such
event, the right of any such Holder's Registrable Securities to be included in a
registration pursuant to this Section 2.3 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with
the managing underwriter or underwriter(s) selected for such underwriting.
Notwithstanding any other provision of this Agreement, if the managing
underwriter determine(s) in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the managing
underwriter(s) may exclude shares (including Registrable Securities) from the
registration and the underwriting, and the number of shares that may be included
in the registration and the underwriting shall be allocated, first, to
shareholders exercising any demand registration rights, second to the Company,
and third, to each of the Holders requesting inclusion of their Registrable
Securities in such registration statement on a pro rata basis based on the total
number of Registrable Securities then held by each such Holder, provided
however, that the right of the underwriters to exclude shares (including
Registrable Securities) from the registration and underwriting as described
above shall be restricted so that: (i) the number of Registrable Securities
included in any such registration is not reduced below twenty-five percent (25%)
of the shares included in the registration, except for a registration relating
to the Company's initial public offering from which all Registrable Securities
may be excluded. If any Holder disapproves of the terms of any such
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company and the underwriter, delivered at least twenty (20) days prior to
the effective date of the registration statement. Any Registrable Securities
excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the registration. For any Holder that is a partnership or corporation, the
partners, retired partners and shareholders of such Holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons shall be deemed to be a single "Holder,"
and any pro rata reduction with respect to such "Holder" shall be based upon the
aggregate amount of shares carrying registration rights owned by all entities
and individuals included in such "Holder," as defined in this sentence.

                    (b) Expenses. All expenses incurred in connection with a
registration pursuant to this Section 2.3 (excluding underwriters' and brokers'
discounts and commissions), including, without limitation all federal and "blue
sky" registration and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company and reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company.

               2.4 Form S-3 Registration. In case the Company shall receive from
any Holder or Holders of Registrable Securities a written request or requests
that the Company effect a registration on Form S-3 and any related qualification
or compliance with respect to all or a part of the Registrable Securities owned
by such Holder or Holders, then the Company will:

                    (a) Notice. Promptly give written notice of the proposed
registration and the Holder's or Holders' request therefor, and any related
qualification or compliance, to all other Holders of Registrable Securities; and

                    (b) Registration. As soon as practicable, effect such
registration and all such qualifications and compliances as may be so requested
and as would permit or facilitate the sale and distribution of all or such
portion of such Holder's or Holders' Registrable Securities as are specified in
such request, together with all or such portion of the Registrable Securities of
any other Holder or Holders joining in such request as are specified in a
written request given within twenty (20) days after receipt of such written
notice from the Company; provided, however, that the Company shall not be
obligated to effect any such registration, qualification or compliance pursuant
to this Section 2.4:

                         (1) if Form S-3 is not available for such offering;

                         (2) if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public of less than $1,000,000;

                         (3) if the Company shall furnish to the Holders a
certificate signed by the President or Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its shareholders
for such Form S-3 Registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement no more than once during any twelve month period for a period of not
more than sixty (60) days after receipt of the request of the Holder or Holders
under this Section 2.4;

                         (4) if the Company has, within the six (6) month period
preceding the date of such request, already effected one (1) registration on
Form S-3 for the Holders pursuant to this Section 2.4; or

                         (5) in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance.

                    (c) Expenses. Subject to the foregoing, the Company shall
file a Form S-3 registration statement covering the Registrable Securities and
other securities so requested to be registered pursuant to this Section 2.4 as
soon as practicable after receipt of the request or requests of the Holders for
such registration. The Company shall pay all expenses incurred in connection
with the first four (4) registrations requested pursuant to this Section 2.4,

   129

(excluding underwriters' or brokers' discounts and commissions), including
without limitation all federal and "blue sky" registration and qualification,
printers' and accounting fees and the reasonable fees and disbursements of one
counsel for the selling Holder or Holders and counsel for the Company. All
expenses incurred in connection with any subsequent registration requested
pursuant to this Section 2.4 shall be borne by the Holders who participate in
such registration on a pro rata basis according to the number of Registrable
Securities owned by the Holders that are included in such registration at the
time it goes effective.

                    (d) Not Demand Registration. Form S-3 registrations shall
not be deemed to be demand registrations as described in Section 2.2 above.

               2.5 Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities under this Agreement, the Company
shall, as expeditiously as reasonably possible:

                    (a) Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use reasonable, diligent efforts
to cause such registration statement to become effective, and, upon the request
of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for up to one hundred
twenty (120) days.

                    (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                    (c) Furnish to the Holders such number of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by them that are included in such registration.

                    (d) Use reasonable, diligent efforts to register and qualify
the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders, provided that the Company shall not be required in
connection 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.

                    (e) 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(s) of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                    (f) Notify each Holder of 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

   130

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.

                    (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities, on the date that such Registrable
Securities are delivered to the underwriters for sale, 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, (1) an opinion, dated as of 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 satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities and (2) a
"comfort" letter dated as of 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 satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities.

               2.6 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 2.2, 2.3 or
2.4 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to timely effect
the registration of their Registrable Securities.

               2.7 Delay of Registration. No Holder shall 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 2.

               2.8 Indemnification. In the event any Registrable Securities are
included in a registration statement under Sections 2.2, 2.3 or 2.4:

                    (a) By the Company. To the extent permitted by law, the
Company will indemnify and hold harmless each Holder, the partners, officers and
directors of each Holder, any underwriter (as defined in the Securities Act) for
such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act against any losses,
claims, damages, or liabilities (joint or several) to which they may become
subject under the Securities Act, the l934 Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively, "VIOLATIONS" and, individually, a
"VIOLATION"):

                         (1) any untrue statement or alleged untrue statement of
a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto;

   131

                         (2) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or

                         (3) any violation or alleged violation by the Company
of the Securities Act, the Exchange Act, any federal or state securities law or
any rule or regulation promulgated under the Securities Act, the Exchange Act or
any federal or state securities law in connection with the offering covered by
such registration statement; 

and the Company will reimburse each such Holder, partner, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability or action; provided however, that the
indemnity agreement contained in this Section 2.8(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, partner, officer, director, underwriter
or controlling person of such Holder.

                    (b) By Selling Holders. To the extent permitted by law, each
selling Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company within the meaning of the Securities
Act, any underwriter and any other Holder selling securities under such
registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, partner or
director, officer or controlling person of such other Holder may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by such Holder expressly for
use in connection with such registration; and each such Holder will reimburse
any legal or other expenses reasonably incurred by the Company or any such
director, officer, controlling person, underwriter or other Holder, partner,
officer, director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this Section 2.8(b)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld; and provided further,
that the total amounts payable in indemnity by a Holder under this Section
2.8(b) in respect of any Violation shall not exceed the net proceeds received by
such Holder in the registered offering out of which such Violation arises.
   132

                    (c) Notice. Promptly after receipt by an indemnified party
under this Section 2.8 of notice of the commencement of any action (including
any governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 2.8,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 2.8, but the omission so to deliver written
notice to the indemnifying party will not relieve it of any liability that it
may have to any indemnified party otherwise than under this Section 2.8.

                    (d) Defect Eliminated in Final Prospectus. The foregoing
indemnity agreements of the Company and Holders are subject to the condition
that, insofar as they relate to any Violation made in a preliminary prospectus
but eliminated or remedied in the amended prospectus on file with the SEC at the
time the registration statement in question becomes effective or the amended
prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "FINAL
PROSPECTUS"), such indemnity agreement shall not inure to the benefit of any
person if a copy of the Final Prospectus was furnished to the indemnified party
and was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

                    (e) Contribution. In order to provide for just and equitable
contribution to joint liability under the Securities Act in any case in which
either (1) any Holder exercising rights under this Agreement, or any controlling
person of any such Holder, makes a claim for indemnification pursuant to this
Section 2.8 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 2.8 provides
for indemnification in such case, or (2) contribution under the Securities Act
may be required on the part of any such selling Holder or any such controlling
person in circumstances for which indemnification is provided under this Section
2.8; then, and in each such case, the Company and such Holder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion so that such Holder
is responsible for the portion represented by the percentage that the public
offering price of its Registrable Securities offered by and sold under the
registration statement bears to the public offering price of all securities
offered by and sold under such registration statement, and the Company and other
selling Holders are responsible for the remaining portion; provided, however,
that, in any such case, (A) no such Holder will be required to contribute any
amount in excess of the public offering price of 

   133
all such Registrable Securities offered and sold by such Holder pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

                    (f) Survival. The obligations of the Company and Holders
under this Section 2.8 shall survive the completion of any offering of
Registrable Securities in a registration statement, and otherwise.

               2.9 "Market Stand-Off" Agreement.

                    (a) Each Holder hereby agrees that it shall not, to the
extent requested by the Company or an underwriter of securities of the Company,
sell or otherwise transfer or dispose of any Registrable Securities or other
shares of stock of the Company then owned by such Holder (other than to donees
or partners of the Holder who agree to be similarly bound) for up to one hundred
eighty (180) days following the effective date of a registration statement of
the Company filed under the Securities Act; provided, however, that such
agreement shall be applicable only to the first such registration statement of
the Company which covers securities to be sold on its behalf to the public in an
underwritten offering but not to any Registrable Securities sold pursuant to
such registration statement.

                    (b) In order to enforce the market stand-back agreement in
this Section 2.9, the Company shall have the right to place restrictive legends
on the certificates representing the shares subject hereto and to impose stop
transfer instructions with respect to the Registrable Securities and such other
shares of stock of each Holder (and the shares or securities of every other
person subject to the foregoing restriction) until the end of such period.

               2.10 Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:

                    (a) Make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times after the effective date of the first registration under the Securities
Act filed by the Company for an offering of its securities to the general
public;

                    (b) File with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements); and

                    (c) So long as a Holder owns any Registrable Securities, to
furnish to the Holder forthwith upon request a written statement by the Company
as to its compliance with the reporting requirements of said Rule 144 (at any
time after 90 days after the effective date of the first registration statement
filed by the Company for an offering of its securities to the general public),
and of the Securities Act and the Exchange Act (at any time after it has become
subject 

   134

to the reporting requirements of the Exchange Act), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
of the Company as a Holder may reasonably request in availing itself of any rule
or regulation of the Commission allowing a Holder to sell any such securities
without registration (at any time after the Company has become subject to the
reporting requirements of the Exchange Act).

               2.11 Termination of the Company's Obligations. The Company shall
have no obligations pursuant to Sections 2.2 through 2.4 with respect to: (a)
any request or requests for registration made by any Holder on a date more than
five (5) years after the closing date of the Company's initial public offering;
or (b) any Registrable Securities proposed to be sold by a Holder in a
registration pursuant to Section 2.2, 2.3 or 2.4 if, in the opinion of counsel
to the Company, all such Registrable Securities proposed to be sold by a Holder
may be sold in a three-month period without registration under the Securities
Act pursuant to Rule 144 under the Securities Act.

        3.      RIGHT OF FIRST REFUSAL.

               3.1 General. Each Holder (as defined in Section 2.1(d)) and any
party to whom such Holder's rights under this Section 3 have been duly assigned
in accordance with Section 4.1(b) (each such Holder or assignee being
hereinafter referred to as a "RIGHTS HOLDER") has a right of first refusal to
purchase such Rights Holder's Pro Rata Share (as defined below), of all (or any
part) of any "New Securities" (as defined in Section 3.2) that the Company may
from time to time issue after the date of this Agreement, provided, however,
that no Holder will be entitled to such right of first refusal if, at the time
of the Company's offer of such New Securities, the Holder is not an "accredited
investor" as that term is defined in Section 501(a) of Regulation D promulgated
by the Commission under the Securities Act. A Rights Holder's "PRO RATA SHARE"
for purposes of this right of first refusal is the ratio of (a) the number of
Registrable Securities as to which such Rights Holder is the Holder (and/or is
deemed to be the Holder under Section 2.1(d)), to (b) the number of shares of
Common Stock of the Company equal to the sum of (1) the total number of shares
of Common Stock of the Company then outstanding plus (2) the total number of
shares of Common Stock issuable upon exercise or conversion of all Preferred
Stock of the Company then outstanding plus (3) the number of shares of Common
Stock of the Company issuable upon exercise and/or conversion of all rights,
options or warrants to purchase such Common Stock or Preferred Stock of the
Company then outstanding.

               3.2 New Securities. "NEW SECURITIES" shall mean any Common Stock
or Preferred Stock of the Company, whether now authorized or not, and rights,
options or warrants to purchase such Common Stock or Preferred Stock, and
securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or Preferred Stock; provided, however, that
the term "New Securities" does not include:

                    (a) shares of Common Stock issued or issuable upon
conversion of the outstanding shares of the Preferred Stock;

                    (b) any shares of Common Stock or Preferred Stock (or
options, warrants or rights therefor) granted or issued hereafter to employees,
officers, directors, 

   135

contractors, consultants or advisers to, the Company or any Subsidiary pursuant
to incentive agreements, stock purchase or stock option plans, stock bonuses or
awards, warrants, contracts or other arrangements that are approved by the Board
of Directors;

                    (c) any shares of the Company's Common Stock or Preferred
Stock (and/or options, warrants or rights therefor) issued or issuable to (i)
parties providing the Company with equipment leases, real property leases,
loans, credit lines, guaranties of indebtedness or similar financing or (ii)
providers of goods and services or (iii) providers or developers of content or
technology, or strategic or commercial partners of the Company; provided that
such arrangements, in each case, are approved by the Board of Directors and are
for primarily non-equity financing purposes;

                    (d) shares of Common Stock or Preferred Stock (and/or
options, warrants or rights therefor) issued pursuant to the acquisition of
another corporation or entity by the Company by consolidation, merger, purchase
of all or substantially all of the assets, or other reorganization in which the
Company acquires, in a single transaction or series of related transactions, all
or substantially all of the assets of such other corporation or entity or fifty
percent (50%) or more of the voting power of such other corporation or entity or
fifty percent (50%) or more of the equity ownership of such other entity;

                    (e) any shares of Series A Stock issued under the Formation
Agreement, any shares of Series B Stock issued under the Series B Agreement and
any shares of Series C Stock issued under the Merger Agreement, as such
agreements may be amended;

                    (f) any securities issuable upon exercise of any options,
warrants or rights to purchase any securities of the Company outstanding on the
date of this Agreement ("WARRANT SECURITIES") and any securities issuable upon
the conversion of any Warrant Securities or upon the exercise or conversion of
any securities, if such securities were first offered to the Rights Holders
hereunder;

                    (g) shares of the Company's Common Stock or Preferred Stock
issued in connection with any stock split or stock dividend; and

                    (h) securities offered by the Company to the public pursuant
to a registration statement filed under the Securities Act.

               3.3 Procedures. In the event that the Company proposes to
undertake an issuance of New Securities, it shall give to each Rights Holder
written notice of its intention to issue New Securities (the "NOTICE"),
describing the type of New Securities and the price and the general terms upon
which the Company proposes to issue such New Securities. Each Rights Holder
shall have twenty (20) days from the date of mailing of any such Notice to agree
in writing to purchase such Rights Holder's Pro Rata Share of such New
Securities for the price and upon the general terms specified in the Notice by
giving written notice to the Company and stating therein the quantity of New
Securities to be purchased (not to exceed such Rights Holder's Pro Rata Share)
and to execute and deliver to the Company such other documentation as may be
reasonably required by the Company to demonstrate that such Rights Holder is, at
the 

   136

time of such offer of New Securities, an "accredited investor" as defined in
Regulation D. If any Rights Holder fails to so agree in writing and to
demonstrate such Rights Holder's status as an "accredited investor" within such
twenty (20) day period to purchase such Rights Holder's full Pro Rata Share of
an offering of New Securities (a "NONPURCHASING HOLDER"), then such
Nonpurchasing Holder shall forfeit the right hereunder to purchase that part of
his Pro Rata Share of such New Securities that he did not so agree to purchase
and the Company shall promptly give each Rights Holder who has timely agreed to
purchase his full Pro Rata Share of such offering of New Securities and
demonstrated his status as an "accredited investor" (a "PURCHASING HOLDER")
written notice of the failure of any Nonpurchasing Holder to purchase such
Nonpurchasing Rights Holder's full Pro Rata Share of such offering of New
Securities (the "OVERALLOTMENT NOTICE"). Each Purchasing Holder shall have a
right of overallotment such that such Purchasing Holder may agree to purchase a
portion of the Nonpurchasing Holders' unpurchased Pro Rata Shares of such
offering on a pro rata basis according to the relative Pro Rata Shares of the
Purchasing Rights Holders, at any time within ten (10) days after receiving the
Overallotment Notice.

               3.4 Failure to Exercise. In the event that the Rights Holders
fail to exercise in full the right of first refusal within such twenty (20) plus
ten (10) day period, then the Company shall have ninety (90) days thereafter to
sell the New Securities with respect to which the Rights Holders' rights of
first refusal hereunder were not exercised, at a price and upon general terms
not materially more favorable to the purchasers thereof than specified in the
Company's Notice to the Rights Holders. In the event that the Company has not
issued and sold the New Securities within such ninety (90) day period, then the
Company shall not thereafter issue or sell any New Securities without again
first offering such New Securities to the Rights Holders pursuant to this
Section 3.

               3.5 Termination. This right of first refusal shall terminate (a)
immediately before the initial closing of the first underwritten sale of Common
Stock of the Company to the public pursuant to a registration statement filed
with, and declared effective by, the SEC under the Securities Act, covering the
offer and sale of Common Stock to the public at an offering price of at least
$5.00 per share (such offering price being subject to proportional adjustment to
reflect subdivisions, combinations, stock dividends and similar transactions
affecting the number of outstanding shares of Common Stock) for an aggregate
gross public offering price (calculated before deduction of underwriters'
discounts and commissions) of at least $25,000,000 and shall not extend to
shares of Common Stock sold in such offering, or (b) upon (1) the acquisition of
all or substantially all the assets of the Company or (2) an acquisition of the
Company by another corporation or entity by consolidation, merger or other
reorganization in which the holders of the Company's outstanding voting stock
immediately prior to such transaction own, immediately after such transaction,
securities representing less than fifty percent (50%) of the voting power of the
corporation or other entity surviving such transaction.

               3.6 Waiver. The right of first refusal provided in this Section 3
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and 

   137

Investors (and/or any of their permitted successors or assigns) holding
sixty-six percent (66%) of all the Registrable Securities then outstanding.

        4.      ASSIGNMENT AND AMENDMENT.

               4.1 Assignment. Notwithstanding anything herein to the contrary:

                    (a) Information Rights. The rights of an Investor under
Section 1.1 hereof may be assigned only to a party who acquires from an Investor
(or an Investor's permitted assigns) at least that number of shares of Preferred
Stock and/or an equivalent number (on an as-converted basis) of shares of
Conversion Stock described in Section 1.1 hereof.

                    (b) Registration Rights; Refusal Rights. The registration
rights of a Holder under Section 2 hereof and the rights of first refusal of a
Rights Holder under Section 3 hereof may be assigned only to a party who

The parties hereto recognize that Employee has unique knowledge and experience regarding Atom's business, and Shockwave and Atom desire to be assured that confidential information pertaining to Atom's business and the goodwill of Atom will be preserved and protected and will inure to the benefit of Shockwave.

Employee agrees that the termination of his employment with Atom to effect the transfer of his employment from Atom to Shockwave at the Employment Effective Date or from Shockwave to any parent, subsidiary or successor of Shockwave thereafter shall not constitute a termination of his employment under this Agreement.

If Shockwave terminates Employee for Cause, this Agreement shall terminate and Employee shall not be entitled to any further benefits hereunder, except for accrued and unpaid salary and vacation. For purposes of this Agreement, "CAUSE" shall mean: (i) Employee's willful misconduct in the performance of Employee's material duties, including Employee's failure to follow the reasonable and lawful directions of the person to whom Employee reports which are consistent with Employee's position and duties, provided that (a) Employee is given written notice from Shockwave setting forth with reasonable specificity such misconduct or failure and giving Employee notice that failure to cure such misconduct or failure will result in termination of Employee for Cause, and (b) Employee's failure to correct the behavior described in the notice within 15 business days following receipt of such notice; (ii) Employee's commission of a felony offense, plea of "guilty" or "no contest" to a felony offense or commission of any unlawful act which would be materially detrimental to the reputation of Shockwave or its affiliates, or a material act of dishonesty, fraud, embezzlement, misappropriation or financial dishonesty against Shockwave or its affiliates; (iii) Employee's material breach of this Agreement, the Employee Invention Assignment and Confidentiality Agreement, or any other material written agreement between Shockwave and Employee, or Employee's material breach or violation of any lawful material employment policy of Shockwave, including those prohibiting harassment of another employee, provided that any such Shockwave employment policies are not inconsistent with the provisions of this Agreement; or (iv) Employee's failure to relocate to the San Francisco, California area within 180 days of the Effective Time of the Merger, or make himself reasonably physically available in San Francisco during regular business days and hours beginning no later than 90 days of the Effective Date of Merger.

(d) Upon Death or Disability.

LABOR CODE SECTION 2870 NOTICE. I have been notified and understand that the provisions of Sections 3 and 5 of this Agreement do not apply to any Assigned Invention that qualifies fully under the provisions of Section 2870 of the California Labor Code, which states as follows: ANY PROVISION IN AN EMPLOYMENT AGREEMENT WHICH 13 171 PROVIDES THAT AN EMPLOYEE SHALL ASSIGN, OR OFFER TO ASSIGN, ANY OF HIS OR HER RIGHTS IN AN INVENTION TO HIS OR HER EMPLOYER SHALL NOT APPLY TO AN INVENTION THAT THE EMPLOYEE DEVELOPED ENTIRELY ON HIS OR HER OWN TIME WITHOUT USING THE EMPLOYER'S EQUIPMENT, SUPPLIES, FACILITIES, OR TRADE SECRET INFORMATION EXCEPT FOR THOSE INVENTIONS THAT EITHER: (1) RELATE AT THE TIME OF CONCEPTION OR REDUCTION TO PRACTICE OF THE INVENTION TO THE EMPLOYER'S BUSINESS, OR ACTUAL OR DEMONSTRABLY ANTICIPATED RESEARCH OR DEVELOPMENT OF THE EMPLOYER; OR (2) RESULT FROM ANY WORK PERFORMED BY THE EMPLOYEE FOR THE EMPLOYER. TO THE EXTENT A PROVISION IN AN EMPLOYMENT AGREEMENT PURPORTS TO REQUIRE AN EMPLOYEE TO ASSIGN AN INVENTION OTHERWISE EXCLUDED FROM BEING REQUIRED TO BE ASSIGNED UNDER CALIFORNIA LABOR CODE SECTION 2870(a), THE PROVISION IS AGAINST THE PUBLIC POLICY OF THIS STATE AND IS UNENFORCEABLE. 5. ASSIGNMENT OF OTHER RIGHTS. In addition to the foregoing assignment of Assigned Inventions to the Company, I hereby irrevocably transfer and assign to the Company: (i) all worldwide patents, patent applications, copyrights, mask works, trade secrets and other intellectual property rights in any Assigned Inventions; and (ii) any and all "Moral Rights" (as defined below) that I may have in or with respect to any Assigned Inventions. I also hereby forever waive and agree never to assert any and all Moral Rights I may have in or with respect to any Assigned Inventions, even after termination of my work on behalf of the Company. "MORAL RIGHTS" mean any rights to claim authorship of an Assigned Inventions, to object to or prevent the modification of any Assigned Inventions, or to withdraw from circulation or control the publication or distribution of any Assigned Inventions, and any similar right, existing under judicial or statutory law of any country in the world, or under any treaty, regardless of whether or not such right is denominated or generally referred to as a "moral right". 6. ASSISTANCE. I agree to assist the Company in every proper way to obtain for the Company and enforce patents, copyrights, mask work rights, trade secret rights and other legal protections for the Company's Assigned Inventions in any and all countries. I will execute any documents that the Company may reasonably request for use in obtaining or enforcing such patents, copyrights, mask work rights, trade secrets and other legal protections. My obligations under this paragraph will continue beyond the termination of my employment with the Company, provided that the Company will compensate me at a reasonable rate after such termination for time or expenses actually spent by me at the Company's request on such assistance. I appoint the Secretary of the Company as my attorney-in-fact to execute documents on my behalf for this purpose should I be unavailable or unwilling to do so. 7. PROPRIETARY INFORMATION. I understand that my employment by the Company creates a relationship of confidence and trust with respect to any information of a confidential or 14 172 secret nature that may be disclosed to me by the Company that relates to the business of the Company, to its predecessor division within Macromedia, Inc., or to the business of any parent, subsidiary, affiliate, customer or supplier of the Company or any other party with whom the Company agrees to hold information of such party in confidence (the "PROPRIETARY INFORMATION"). Such Proprietary Information includes, but is not limited to, Assigned Inventions, marketing plans, product plans, business strategies, financial information, forecasts, personnel information, customer lists and domain names. 8. CONFIDENTIALITY. At all times, both during my employment and after its termination, I will keep and hold all such Proprietary Information in strict confidence and trust. I will not use or disclose any Proprietary Information without the prior written consent of the Company, except as may be necessary to perform my duties as an employee of the Company for the benefit of the Company. Upon termination of my employment with the Company, I will promptly deliver to the Company all documents and materials of any nature pertaining to my work with the Company. I will not take with me any documents or materials or copies thereof containing any Proprietary Information. 9. NO BREACH OF PRIOR AGREEMENT. I represent that my performance of all the terms of this Agreement and my duties as an employee of the Company will not breach any invention assignment, proprietary information, confidentiality or similar agreement with any former employer or other party. I represent that I will not bring with me to the Company or use in the performance of my duties for the Company any documents or materials or intangibles of a former employer or third party that are not generally available to the public or have not been legally transferred to the Company. 10. NOTIFICATION. I hereby authorize the Company to notify my actual or future employers of the terms of this Agreement and my responsibilities hereunder. 11. INJUNCTIVE RELIEF. I understand that in the event of a breach or threatened breach of this Agreement by me the Company may suffer irreparable harm and will therefore be entitled to injunctive relief to enforce this Agreement. 12. GOVERNING LAW; SEVERABILITY. This Agreement will be governed by and construed in accordance with the laws of the State of California, without giving effect to that body of laws pertaining to conflict of laws. If any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced, such provision shall be stricken from this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement. Notwithstanding the forgoing, if the value of this Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be binding, then this Agreement will not be enforceable against such affected party and both parties agree to renegotiate such provision(s) in good faith. 15 173 13. COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered will be deemed an original, and all of which together shall constitute one and the same agreement. 14. ENTIRE AGREEMENT. This Agreement and the documents referred to herein constitute the entire agreement and understanding of the parties with respect to the subject matter of this Agreement, and supersede all prior understandings and agreements, whether oral or written, between or among the parties hereto with respect to the specific subject matter hereof. 15. AMENDMENT AND WAIVERS. This Agreement may be amended only by a written agreement executed by each of the parties hereto. No amendment of or waiver of, or modification of any obligation under this Agreement will be enforceable unless set forth in a writing signed by the party against which enforcement is sought. Any amendment effected in accordance with this section will be binding upon all parties hereto and each of their respective successors and assigns. No delay or failure to require performance of any provision of this Agreement shall constitute a waiver of that provision as to that or any other instance. No waiver granted under this Agreement as to any one provision herein shall constitute a subsequent waiver of such provision or of any other provision herein, nor shall it constitute the waiver of any performance other than the actual performance specifically waived. 16. SUCCESSORS AND ASSIGNS; ASSIGNMENT. Except as otherwise provided in this Agreement, this Agreement, and the rights and obligations of the parties hereunder, will be binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators and legal representatives. The Company may assign any of its rights and obligations under this Agreement. No other party to this Agreement may assign, whether voluntarily or by operation of law, any of its rights and obligations under this Agreement, except with the prior written consent of the Company. 17. FURTHER ASSURANCES. The parties agree to execute such further documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement. 16 174 18. "AT WILL" EMPLOYMENT. I understand that this Agreement does not constitute a contract of employment or obligate the Company to employ me for any stated period of time. I understand that I am an "at will" employee of the Company. This Agreement shall be effective as of the first day of my employment by the Company. SHOCKWAVE.COM, INC.

CONVERTIBLE PROMISSORY NOTE OF ATOM CORPORATION $ 5,000,000.00 Issue Date: December 15, 2000 Maturity Date: December 15, 2001 1. OBLIGATION. The undersigned, Atom Corporation ("BORROWER"), hereby promises to pay to the order of Macromedia, Inc., ("LENDER" OR "HOLDER") on December 15, 2001, at Lender's principal place of business at 600 Townsend Street, San Francisco, CA 94103, or at such other place as Holder may direct, the principal sum of Five Million Dollars ($5,000,000.00) plus accrued interest at a rate of 6.10 percent (6.10%) per annum, compounded annually, which rate is not less than the minimum rate established pursuant to Section 1274(d) of the Internal Revenue Code of 1986, as amended, as of the date hereof. As used herein, the term "HOLDER" shall initially mean Lender, and shall subsequently mean each person or entity to which this Note is duly assigned. This Note shall be entered into pursuant to a Note Purchase Agreement dated December 14, 2000 (the "NOTE AGREEMENT") between Lender and Borrower. 2. DEFAULT; ACCELERATION OF OBLIGATION. Borrower will be deemed to be in default under this Note and the outstanding unpaid principal balance of this Note, together with all interest accrued thereon, will immediately become due and payable in full, without the need for any further action on the part of Holder, upon the occurrence of any of the following events (each an "EVENT OF DEFAULT"): (a) upon Borrower's failure to make any payment when due under this Note; (b) upon the filing by or against Borrower of any voluntary or involuntary petition in bankruptcy or any petition for relief under the federal bankruptcy code or any other state or federal law for the relief of debtors; provided, however, with respect to an involuntary petition in bankruptcy, such petition has not been dismissed within thirty (30) days after the filing of such petition; (c) upon the execution by Borrower of an assignment for the benefit of creditors or the appointment of a receiver, custodian, trustee or similar party to take possession of Borrower's assets or property; or (d) material breach of the terms and conditions of the Note Agreement. 184 3. REMEDIES ON DEFAULT; ACCELERATION. Upon any Event of Default, Holder will have, in addition to its rights and remedies under this Note, full recourse against any real, personal, tangible or intangible assets of Borrower, and may pursue any legal or equitable remedies that are available to Holder, and may declare the entire unpaid principal amount of this Note and all unpaid accrued interest under this Note to be immediately due and payable in full. 4. CONVERSION. Upon the closing of the Merger (as referred to in the Note Agreement), all of Shockwave's indebtedness under this Note shall become convertible into equity securities of the surviving corporation, Shockwave (the "SERIES NEXT PREFERRED STOCK"), issued in Shockwave's next private equity financing (the "NEXT EQUITY FINANCING"), provided the Next Equity Financing closes prior to the Maturity Date of this Note. Upon the Next Equity Financing, Borrower's indebtedness under this Note shall automatically be converted into that number of fully paid and nonassessable shares of Shockwave's Series Next Preferred Stock that is equal to the dollar amount of all principal outstanding and interest accrued as of the date of conversion being converted into stock by Holder, divided by the price per share of Shockwave's Series Next Preferred Stock at which such Series Next Preferred Stock is or will be offered to other Series Next Preferred Stock investors (the "CONVERSION PRICE"); provided, however, that the Conversion Price will automatically, equitably and proportionally be adjusted to reflect any subdivision (stock split), combination (reverse stock split), stock dividend or other recapitalization affecting Shockwave's Series Next Preferred Stock. In the event that the Merger Agreement (as referred to in the Note Agreement) is terminated according to its terms, all of Borrower's indebtedness under this Note shall automatically be converted into Borrower's Series D Preferred Stock based upon a fully diluted pre-money valuation of Borrower's equity of $75,000,000 (the "BORROWER CONVERSION PRICE"); provided, however, that the Conversion Price will automatically, equitably and proportionally be adjusted to reflect any subdivision (stock split), combination (reverse stock split), stock dividend or other recapitalization affecting Borrower's Series D Preferred Stock. Such Series D Preferred Stock received by Holder will have rights, privileges, preferences and restrictions no less favorable than Borrower's Series C Preferred Stock in existence on the date of the Note Agreement and any Series D Preferred Stock issued subsequent to that date, and will have a liquidation preference based upon the price per share of the Series D Preferred Stock. Borrower covenants and agrees with Holder that Borrower will not in any way alter, amend or modify any of the rights, preferences, privileges or restrictions of Borrower's Series D Preferred Stock, or to issue, eliminate or reduce the number of authorized shares of Borrower's Series D Preferred Stock. Upon the conversion of Borrower's outstanding indebtedness hereunder pursuant to this Section, Borrower, at its expense, will as soon as practicable cause to be issued in the name of and delivered to Holder, a certificate or certificates for the number of fully paid and nonassessable shares of Borrower's Series D Preferred Stock to which Holder is entitled upon such conversion. Such certificates will include legends required federal and applicable state securities laws. No fractional shares will be issued upon any conversion of this Note or any part hereof. If, upon any conversion of this Note, a fraction of a share would otherwise result, then Shockwave or Borrower, as the case may be, will pay Holder an amount of cash equal to the fair market value of one share of the type and class of capital stock issuable to Holder upon such conversion (determined in accordance with the Conversion Price or Borrower Conversion Price, as the case may be, applicable at the time of -2- 185 such conversion), multiplied by the fraction of a share of stock to which Holder would otherwise be entitled. 5. WAIVER AND AMENDMENT. Any provision of this Note may be amended or modified only by a writing signed by both Borrower and Holder. Except as provided below with respect to waivers by Borrower, no waiver or consent with respect to this Note will be binding or effective unless it is set forth in writing and signed by the party against whom such waiver is asserted. No course of dealing between Borrower and Holder will operate as a waiver or modification of any party's rights or obligations under this Note. No delay or failure on the part of either party in exercising any right or remedy under this Note will operate as a waiver of such right or any other right. A waiver given on one occasion will not be construed as a bar to, or as a waiver of, any right or remedy on any future occasion. 6. WAIVERS OF BORROWER. Borrower hereby waives presentment, notice of non-payment, notice of dishonor, protest, demand and diligence. This Note may be amended only by a writing executed by Borrower and Holder. 7. GOVERNING LAW.

CONVERTIBLE PROMISSORY NOTE OF ATOM CORPORATION $ 5,000,000.00 Issue Date: January __, 2001 Maturity Date: January __, 2002 1. OBLIGATION. The undersigned, Atom Corporation ("BORROWER"), hereby promises to pay to the order of Macromedia, Inc., ("LENDER" OR "HOLDER") on January __, 2002, at Lender's principal place of business at 600 Townsend Street, San Francisco, CA 94103, or at such other place as Holder may direct, the principal sum of Five Million Dollars ($5,000,000.00) plus accrued interest at a rate of 6.10 percent (6.10%) per annum, compounded annually, which rate is not less than the minimum rate established pursuant to Section 1274(d) of the Internal Revenue Code of 1986, as amended, as of the date hereof. As used herein, the term "HOLDER" shall initially mean Lender, and shall subsequently mean each person or entity to which this Note is duly assigned. This Note shall be entered into pursuant to a Note Purchase Agreement dated December 14, 2000 (the "NOTE AGREEMENT") between Lender and Borrower. 2. DEFAULT; ACCELERATION OF OBLIGATION. Borrower will be deemed to be in default under this Note and the outstanding unpaid principal balance of this Note, together with all interest accrued thereon, will immediately become due and payable in full, without the need for any further action on the part of Holder, upon the occurrence of any of the following events (each an "EVENT OF DEFAULT"): (a) upon Borrower's failure to make any payment when due under this Note; (b) upon the filing by or against Borrower of any voluntary or involuntary petition in bankruptcy or any petition for relief under the federal bankruptcy code or any other state or federal law for the relief of debtors; provided, however, with respect to an involuntary petition in bankruptcy, such petition has not been dismissed within thirty (30) days after the filing of such petition; (c) upon the execution by Borrower of an assignment for the benefit of creditors or the appointment of a receiver, custodian, trustee or similar party to take possession of Borrower's assets or property; or (d) material breach of the terms and conditions of the Note Agreement. 189 3. REMEDIES ON DEFAULT; ACCELERATION. Upon any Event of Default, Holder will have, in addition to its rights and remedies under this Note, full recourse against any real, personal, tangible or intangible assets of Borrower, and may pursue any legal or equitable remedies that are available to Holder, and may declare the entire unpaid principal amount of this Note and all unpaid accrued interest under this Note to be immediately due and payable in full. 4. CONVERSION. Upon the closing of the Merger (as referred to in the Note Agreement), all of Shockwave's indebtedness under this Note shall become convertible into equity securities of the surviving corporation, Shockwave (the "SERIES NEXT PREFERRED Stock"), issued in Shockwave's next private equity financing (the "NEXT EQUITY FINANCING"), provided the Next Equity Financing closes prior to the Maturity Date of this Note. Upon the Next Equity Financing, Borrower's indebtedness under this Note shall automatically be converted into that number of fully paid and nonassessable shares of Shockwave's Series Next Preferred Stock that is equal to the dollar amount of all principal outstanding and interest accrued as of the date of conversion being converted into stock by Holder, divided by the price per share of Shockwave's Series Next Preferred Stock at which such Series Next Preferred Stock is or will be offered to other Series Next Preferred Stock investors (the "CONVERSION PRICE"); provided, however, that the Conversion Price will automatically, equitably and proportionally be adjusted to reflect any subdivision (stock split), combination (reverse stock split), stock dividend or other recapitalization affecting Shockwave's Series Next Preferred Stock. In the event that the Merger Agreement (as referred to in the Note Agreement) is terminated according to its terms, all of Borrower's indebtedness under this Note shall automatically be converted into Borrower's Series D Preferred Stock based upon a fully diluted pre-money valuation of Borrower's equity of $75,000,000 (the "BORROWER CONVERSION PRICE"); provided, however, that the Conversion Price will automatically, equitably and proportionally be adjusted to reflect any subdivision (stock split), combination (reverse stock split), stock dividend or other recapitalization affecting Borrower's Series D Preferred Stock. Such Series D Preferred Stock received by Holder will have rights, privileges, preferences and restrictions no less favorable than Borrower's Series C Preferred Stock in existence on the date of the Note Agreement and any Series D Preferred Stock issued subsequent to that date, and will have a liquidation preference based upon the price per share of the Series D Preferred Stock. Borrower covenants and agrees with Holder that Borrower will not in any way alter, amend or modify any of the rights, preferences, privileges or restrictions of Borrower's Series D Preferred Stock, or to issue, eliminate or reduce the number of authorized shares of Borrower's Series D Preferred Stock. Upon the conversion of Borrower's outstanding indebtedness hereunder pursuant to this Section, Borrower, at its expense, will as soon as practicable cause to be issued in the name of and delivered to Holder, a certificate or certificates for the number of fully paid and nonassessable shares of Borrower's Series D Preferred Stock to which Holder is entitled upon such conversion. Such certificates will include legends required federal and applicable state securities laws. No fractional shares will be issued upon any conversion of this Note or any part hereof. If, upon any conversion of this Note, a fraction of a share would otherwise result, then Shockwave or Borrower, as the case may be, will pay Holder an amount of cash equal to the fair market value of one share of the type and class of capital stock issuable to Holder upon such conversion (determined in accordance with the Conversion Price or Borrower Conversion Price, as the case may be, applicable at the time of -2- 190 such conversion), multiplied by the fraction of a share of stock to which Holder would otherwise be entitled. 5. WAIVER AND AMENDMENT. Any provision of this Note may be amended or modified only by a writing signed by both Borrower and Holder. Except as provided below with respect to waivers by Borrower, no waiver or consent with respect to this Note will be binding or effective unless it is set forth in writing and signed by the party against whom such waiver is asserted.
