                      NON-QUALIFIED STOCK OPTION AGREEMENT

                         UNDER THE PRIMIX SOLUTIONS INC.
                                 1995 STOCK PLAN

      Pursuant to the Primix Solutions Inc. 1995 Stock Plan as amended through
the date hereof (the "Plan"), Primix Solutions Inc. (the "Company") hereby
grants to the Optionee named in Exhibit A attached hereto an option (the "Stock
Option") to purchase on or prior to the Expiration Date specified in Exhibit A
all or part of the number of shares ("Option Shares") of Common Stock, par value
$.001 per share (the "Stock"), of the Company specified in Exhibit A at the
Option Exercise Price per Share specified in Exhibit A subject to the terms and
conditions set forth herein and in the Plan.

      1. Vesting Schedule. No portion of this Stock Option may be exercised
until such portion shall have vested. Except as set forth below, and subject to
the discretion of the Committee (as defined in paragraph 2 of the Plan) to
accelerate the vesting schedule hereunder, for so long as the Optionee is a
director of, or employed as an employee or officer of, or retained to render
services as a consultant of, the Company or a Related Corporation, this Stock
Option shall vest in accordance with the vesting schedule specified in Exhibit
A.

      Unless alternate provisions are made, this Stock Option will terminate
upon the occurrence of (i) the dissolution or liquidation of the Company, (ii) a
merger, consolidation or other business combination in which the Company is
acquired by another entity (other than a holding company formed by the Company)
or in which the Company is not the surviving entity ("Acquisition") or (iii) the
sale of all or substantially all of the assets of the Company to another entity
("Sale"). In the event of a termination due to an Acquisition or Sale, such
portions of this Stock Option which have vested plus such additional portions
which by their terms vest upon an Acquisition or Sale, shall be exercisable for
at least fifteen (15) days prior to the date of such termination.

      2. Manner of Exercise.

            (a) The Optionee may exercise this Stock Option only in the
following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Company of his or her
election to purchase some or all of the vested Option Shares purchasable at the
time of such notice. This notice shall specify the number of Option Shares to be
purchased.

      Payment of the purchase price for the Option Shares may be made by one or
more of the following methods: (i) in cash, by certified or bank check or other
instrument acceptable to the Committee; (ii) by the Optionee delivering to the
Company a properly executed exercise notice together with irrevocable
instructions to a broker to promptly deliver to the Company cash or a check
payable and acceptable to the Company to pay the Stock Option purchase price,
provided that in the event the Optionee chooses to pay the Stock Option purchase
price as so provided, the Optionee and the broker shall comply with such
procedures and enter into such agreements of
<PAGE>

indemnity and other agreements as the Committee shall prescribe as a condition
of such payment procedure; or (iii) at the discretion of the Committee by any
combination of (i) and (ii) above. Payment instruments will be received subject
to collection.

      The delivery of certificates representing the Option Shares will be
contingent upon the Company's receipt from the Optionee of full payment for the
Option Shares, as set forth above and any agreement, statement or other evidence
that the Company may require to satisfy itself that the issuance of Stock to be
purchased pursuant to the exercise of Stock Options under the Plan and any
subsequent resale of the shares of Stock will be in compliance with applicable
laws and regulations.

            (b) Certificates for shares of Stock purchased upon exercise of this
Stock Option shall be issued and delivered to the Optionee upon compliance to
the satisfaction of the Committee with all requirements under applicable laws or
regulations in connection with such issuance and with the requirements hereof
and of the Plan. The determination of the Committee as to such compliance shall
be final and binding on the Optionee. The Optionee shall not be deemed to be the
holder of, or to have any of the rights of a holder with respect to, any shares
of Stock subject to this Stock Option unless and until this Stock Option shall
have been exercised pursuant to the terms hereof, the Company shall have issued
and delivered the shares of Stock to the Optionee, and the Optionee's name shall
have been entered as the stockholder of record on the books of the Company.
Thereupon, the Optionee shall have full voting, dividend and other ownership
rights with respect to such shares of Stock.

            (c) The minimum number of shares with respect to which this Stock
Option may be exercised at any one time shall be 100 shares, unless the number
of shares with respect to which this Stock Option is being exercised is the
total number of shares subject to exercise under this Stock Option at the time.

      3. Termination of Employment. If the Optionee's employment or service
relationship as a director or consultant ("Service Relationship") with the
Company or a Related Corporation (as defined in the Plan) is terminated, this
Stock Option shall no longer vest and the period within which to exercise the
Stock Option to the extent then vested and exercisable may be subject to earlier
termination as set forth below.

            (a) Termination Due to Death. If the Optionee's Service Relationship
with the Company or a Related Corporation terminates by reason of death, any
Stock Option held by the Optionee, to the extent exercisable, may thereafter be
exercised by the Optionee's personal representative or beneficiary who has
acquired the Stock Option by will or by the laws of descent and distribution for
a period of 360 days from the date of death or until the Expiration Date, if
earlier.

            (b) Termination Due to Disability. If the Optionee's Service
Relationship with the Company or a Related Corporation terminates by reason of
disability (as defined in Paragraph 10 of the Plan), any Stock Option held by
the Optionee shall become fully exercisable

                                       2
<PAGE>

and may thereafter be exercised by the Optionee for a period of 360 days from
the date of termination or until the Expiration Date, if earlier.

            (c) Termination of Service Relationship. If the Optionee's Service
Relationship with the Company or a Related Corporation terminates for any reason
other than death or disability (as defined in paragraph 10 of the Plan), and
unless otherwise determined by the Committee, any Stock Option held by the
Optionee may be exercised, to the extent exercisable on the date of termination,
for a period of fifteen (15) days from the date of termination or until the
Expiration Date, if earlier. Any Stock Option that is not exercisable at such
time shall terminate immediately and be of no further force or effect.

            (d) Notwithstanding any other provision hereof or of the Plan, no
portion of this Stock Option shall be exercisable after the Expiration Date
hereof.

      4. Incorporation of Plan. Notwithstanding anything herein to the contrary,
this Stock Option shall be subject to and governed by the terms and conditions
of the Plan. Capitalized terms in this Agreement shall have the meaning
specified in the Plan, unless a different meaning is specified herein or in
Exhibit A attached hereto and incorporated herein.

      5. Transferability. This Agreement is personal to the Optionee, is
non-assignable and is not transferable in any manner, by operation of law or
otherwise, other than by will or the laws of descent and distribution. This
Stock Option is exercisable, during the Optionee's lifetime, only by the
Optionee, and thereafter, only by the Optionee's personal representative or
beneficiary.

      6. Tax Withholding. No later than the date as of which part or all of the
value of any shares of Stock received under the Plan first becomes includible in
the Optionee's gross income for Federal tax purposes, the Optionee shall make
arrangements with the Company in accordance with paragraph 20 of the Plan
regarding payment of any Federal, state or local taxes required to be withheld
with respect to such income.

      7. Miscellaneous.

            (a) Notice hereunder shall be given to the Company at its principal
place of business, and shall be given to the Optionee at the address set forth
below, or in either case at such other address as one party may subsequently
furnish to the other party in writing.

            (b) This Stock Option does not confer upon the Optionee any rights
with respect to continuance of employment by the Company or any Related
Corporation.

            (c) Pursuant to paragraph 16 of the Plan, the Committee may at any
time amend or cancel any outstanding portion of this Stock Option, but no such
action may be taken which adversely affects the Optionee's rights under this
Agreement without the Optionee's consent.

                              PRIMIX SOLUTIONS INC.
                                 1996 Stock Plan
                         Amended as of January 26, 2001

      1. Purpose. This 1996 Stock Plan, as amended (the "Plan") is intended to
provide incentives: (a) to employees of Primix Solutions Inc. (the "Company")
and any Related Corporation (as hereinafter defined) by providing them with
opportunities to purchase stock in the Company pursuant to options granted
hereunder which qualify as "incentive stock options" under Section 422(b) of the
Internal Revenue Code of 1986, as amended (the "Code") ("ISO" or "ISOs"); (b) to
directors, officers, employees and consultants of the Company and Related
Corporations by providing them with opportunities to purchase stock in the
Company pursuant to options granted hereunder which do not qualify as ISOs
("Non-Qualified Option" or "Non-Qualified Options"); and (c) to directors,
officers, employees and consultants of the Company and Related Corporations by
providing them with opportunities to make direct purchases of stock in the
Company ("Purchases"). Both ISOs and Non-Qualified Options are referred to
hereafter individually as an "Option" and collectively as "Options." Options and
authorizations to make Purchases are referred to hereafter collectively as
"Stock Rights." As used herein, the term "Related Corporation" shall include (i)
any corporation with respect to which the Company owns, directly or indirectly,
stock possessing 51 percent or more of the total voting power of all classes of
stock of such corporation and (ii) any corporation which directly owns stock
possessing 51 percent or more of the of the total voting power of all classes of
stock of the Company. As used herein, the terms "parent" and "subsidiary" mean
"parent corporation" and "subsidiary corporation," respectively, as those terms
are defined in Section 424 of the Code.

      2.    Administration of the Plan.

            A. The Plan shall be administered by a stock plan committee (the
"Committee") consisting of not less than two directors of the Company appointed
by the Board of Directors of the Company (the "Board") each of whom (1)
qualifies as a "non-employee director" within the meaning of Rule 16b-3(b)(3)(i)
promulgated under the Securities Exchange Act of 1934, as amended, (the "Act")
and (2) qualifies as an "outside director" within the meaning of Section 162(m)
of the Code on and after the date the Plan becomes subject to such section.
Subject to the terms of the Plan, the Committee shall have the authority to (i)
determine the employees of the Company and Related Corporation (from among the
class of employees eligible under paragraph 4 to receive ISOs) to whom ISOs may
be granted, and to determine (from among the class of individuals and entities
eligible under paragraph 4 to receive Non-Qualified Options and to make
Purchases) to whom Non-Qualified Options and authorizations to make Purchases
may be granted; (ii) determine the time or times at which Options may be granted
or Purchases made; (iii) determine the option price of shares subject to each
Option, which price shall not be less than the minimum price specified in
paragraph 7 and the purchase price of shares subject to each Purchase; (iv)
determine whether each Option granted shall be an ISO or a Non-Qualified Option;
(v) determine (subject to paragraph 8) the

                                       1
<PAGE>

time or times when each Option shall become exercisable and the duration of the
exercise period; (vi) determine what percentage of shares underlying an Option
can be accelerated; (vii) determine whether restrictions such as repurchase
options are to be imposed on shares subject to Options and Purchases and the
nature of such restrictions, if any, (viii) amend or modify any outstanding
Stock Right in a manner which may differ among individual optionees or
purchasers and (ix) interpret the Plan and prescribe and rescind rules and
regulations in accordance with it. The interpretation and construction by the
Committee of any provisions of the Plan or of any Stock Right granted under it
shall be final and binding upon all parties. The Committee may from time to time
adopt such rules and regulations for carrying out the Plan as it may deem best.
No member of the Committee shall be liable for any action or determination made
in good faith with respect to the Plan or any Stock Right granted under it.

            B. The Committee may select one of its members as its chairman, and
shall hold meetings at such time and places as it may determine. Acts by a
majority of the Committee, or acts reduced to or approved in writing by a
majority of the members of the Committee, shall be the valid acts of the
Committee.

            C. The Committee, in its discretion, may delegate to the Chief
Executive Officer of the Company all or part of the Committee's authority and
duties with respect to Options, including the granting thereof, to individuals
who are not subject to the reporting and other provisions of Section 16 of the
Act or "covered employees" within the meaning of Section 162(m) of the Code. The
Committee may revoke or amend the terms of a delegation at any time but such
action shall not invalidate any prior actions of the Committee's delegate or
delegates that were consistent with the terms of the Plan.

      3.    Option Grants to Directors.

            Except as may otherwise be approved by the Board:

            A. Each individual who first becomes a member of the Board after the
date of adoption of this Plan by the Board of Directors shall be granted on the
date such individual first joins the Board an Option to acquire 20,000 shares of
Common Stock.

            B. Each Director who is serving as a Director of the Company on each
January 1 shall automatically be granted on such day an Option to acquire 5,000
shares of Common Stock.

            C. The exercise price per share for the Common Stock covered by an
Option granted hereunder shall be equal to the "fair market value" (as defined
in paragraph 7) of the Common Stock on the date the Option is granted. An Option
granted under this paragraph 3 shall vest as follows: 25% of the total number of
shares underlying the Option

                                       2
<PAGE>

shall vest on the first anniversary of the grant date and 6.25% of the total
number of shares underlying the Option shall vest at the end of each full
calendar quarter thereafter. No Option issued under this paragraph 3 shall be
exercisable after the expiration of ten years from the date upon which such
option is granted.

            D. The rights of a Director in an Option granted under this
paragraph 3 shall terminate 90 days after such Director ceases to be a Director
of the Company or the specified expiration date, if earlier, provided, however,
that any Option granted to a Director and outstanding on the date of his death
may be exercised by the legal representative or legatee of the optionee for a
period of twelve months from the date of death or until the expiration of the
stated term of the option, if earlier.

            E. Options granted under this paragraph 3 may be exercised only by
written notice to the Company specifying the number of shares to be purchased.
Payment of the full purchase price of the shares to be purchased may be made by
one or more of the methods specified in paragraph 15. An individual shall have
the rights of a stockholder only as to shares acquired upon the exercise of an
option and not as to unexercised options.

            F. The provisions of this paragraph 3 shall apply only to Options
granted or to be granted to Directors, and shall not be deemed to modify, limit
or otherwise apply to any other provision of this Plan or to any Option issued
under this Plan to an individual who is not a Director of the Company. To the
extent inconsistent with the provisions of any other paragraph of this Plan, the
provisions of this paragraph 3 shall govern the rights and obligations of the
Company and Directors respecting Options granted or to be granted to Directors.

      4. Eligible Employees and Others. ISOs may be granted to any employee of
the Company or any Related Corporation. Those officers and directors of the
Company who are not employees may not be granted ISOs under the Plan.
Non-Qualified Options and authorizations to make Purchases may be granted to any
director (whether or not an employee), officer, employee or consultant of the
Company or any Related Corporation. The Committee may take into consideration a
recipient's individual circumstances in determining whether to grant an ISO, a
Non-Qualified Option or an authorization to make a Purchase. Granting of any
Stock Right to any individual or entity shall neither entitle such individual or
entity to, nor disqualify such individual or entity from, participation in any
other grant of Stock Rights.

      5. Stock. The stock subject to Options and Purchases shall be authorized
but unissued shares of Common Stock, par value $0.001 per share, of the Company
(the "Common Stock"), or shares of Common Stock reacquired by the Company in any
manner. The aggregate number of shares which may be issued pursuant to the Plan
is 5,500,000, and on and after the date the Plan becomes subject to Section
162(m) of the Code, Options with respect to no more than 333,333 shares of
Common Stock may be granted to any one individual participant during any
calendar year period. Such numbers shall be subject to adjustment as provided in
paragraph 14. Any shares issued hereunder may be issued as ISOs, Non-Qualified
Options, or to persons or

                                       3
<PAGE>

entities making Purchases, so long as the number of shares so issued does not
exceed the aggregate number of shares of Common Stock subject to the Plan. If
any Option granted under the Plan shall expire, be canceled or otherwise
terminate for any reason without having been exercised in full or shall cease
for any reason to be exercisable in whole or in part, or if the Company shall
reacquire any shares issued pursuant to Purchases, the unpurchased shares
subject to such Options and any shares so reacquired by the Company shall again
be available for grants of Stock Rights under the Plan.

      6. Granting of Stock Rights. Stock Rights may be granted under the Plan at
any time on or after May 20, 1996 and prior to May 20, 2006. The date of grant
of a Stock Right under the Plan will be the date specified by the Committee at
the time it grants the Stock Right; provided, however, that such date shall not
be prior to the date on which the Committee acts to approve the grant. The
Committee shall have the right, with the consent of the optionee, to convert an
ISO granted under the Plan to a Non-Qualified Option pursuant to paragraph 17.

      7. Minimum Option Price; ISO Limitations.

            A. The price per share specified in the agreement relating to each
Non-Qualified Option granted under the Plan shall in no event be less than the
lesser of (i) the book value per share of Common Stock as of the end of the
fiscal year of the Company immediately preceding the date of such grant, or (ii)
50 percent of the fair market value per share of Common Stock on the date of
such grant.

            B. The price per share specified in the agreement relating to each
ISO granted under the Plan shall not be less than the fair market value per
share of Common Stock on the date of such grant. In the case of an ISO to be
granted to an employee deemed to own, pursuant to Section 424 of the Code, stock
possessing more than ten percent of the total combined voting power of all
classes of stock of the Company or any parent or subsidiary, the price per share
specified in the agreement relating to such ISO shall not be less than 110
percent of the fair market value per share of Common Stock on the date of grant.

            C. To the extent that the aggregate fair market value (determined at
the time an ISO is granted) of Common Stock for which ISOs granted to any
employee are exercisable for the first time by such employee during any calendar
year (under all stock option plans of the Company and any parent or subsidiary)
exceed $100,000, such ISO shall be deemed to be a Non-Qualified Option.

            D. "Fair market value" of the Company's Common Stock shall be
determined as of the last business day for which the prices or quotes discussed
in this sentence are available prior to the date such Option is granted and
shall mean (i) the last reported sale price (on such date) of the Common Stock
on the principal national securities exchange on which the Common Stock is
traded, if the Common Stock is then traded on a national securities exchange; or
(ii) the

                                       4
<PAGE>

last reported sale price (on such date) of the Common Stock on the National
Market System of The Nasdaq Stock Market, Inc. ("NASDAQ"), if the Common Stock
is not then traded on a national securities exchange; or (iii) the closing bid
price (or average of bid prices) last quoted (on such date) by an established
quotation service for over-the-counter securities, if the Common Stock is not
reported on NASDAQ. Notwithstanding the foregoing, "fair market value" of the
Company's Common Stock on the effective date of the Company's initial public
offering shall be the offering price to the public of the Common Stock on such
date.

      8. Option Duration. Subject to earlier termination as provided in
paragraphs 10 and 11, each Option shall expire on the date specified by the
Committee, but not more than (i) ten years from the date of grant in the case of
Non-Qualified Options, (ii) ten years from the date of grant in the case of ISOs
generally, and (iii) five years from the date of grant in the case of ISOs
granted to an employee deemed to own, pursuant to Section 424 of the Code, stock
possessing more than ten percent of the total combined voting power of all
classes of stock of the Company or any parent or subsidiary. Subject to earlier
termination as provided in paragraphs 10 and 11, the term of each ISO shall be
the term set forth in the original instrument granting such ISO, except with
respect to any part of such ISO that is converted into a Non-Qualified Option
pursuant to paragraph 17.

      9. Exercise of Option. Subject to the provisions of paragraphs 10 through
13, each Option granted under the Plan shall be exercisable as follows:

            A. The Option shall either be fully exercisable on the date of grant
or shall become exercisable thereafter in such installments as the Committee may
specify.

            B. Once an installment becomes exercisable it shall remain
exercisable until expiration or termination of the Option, unless otherwise
specified by the Committee.

            C. Each Option or installment may be exercised at any time or from
time to time, in whole or in part, for up to the total number of shares with
respect to which it is then exercisable.

            D. The Committee shall have the right to accelerate the date of
exercise of any installment of any Option.

      10. Termination of Employment. If an ISO optionee ceases to be employed by
the Company and all Related Corporations other than by reason of death or
disability as defined in paragraph 11, no further installments of his ISOs shall
become exercisable, and his ISOs shall terminate after the passage of three
months from the date of termination of his employment, but in no event later
than on their specified expiration dates, except to the extent that such ISOs
(or unexercised installments thereof) have been converted into Non-Qualified
Options pursuant to paragraph 17. Employment shall be considered as continuing
uninterrupted during any bona fide

                                       5

leave of absence such as those attributable to illness, military obligations or
governmental service) provided that the period of such leave does not exceed 90
days or, if longer, any period during which such optionee's right to
reemployment is guaranteed by statute. A bona fide leave of absence with the
written approval of the Committee shall not be considered an interruption of
employment under the Plan, provided that such written approval contractually
obligates the Company or any Related Corporation to continue the employment of
the optionee after the approved period of absence. Unless otherwise designated
by the Committee or required by law, a leave of absence shall not be treated as
service for purposes of determining vesting pursuant to a Stock Right. ISOs
granted under the Plan shall not be affected by any change of employment within
or among the Company or any Related Corporation, so long as the optionee
continues to be an employee of the Company or any Related Corporation. Nothing
in the Plan shall be deemed to give any grantee of any Stock Right the right to
be retained in employment or other service by the Company or any Related
Corporation for any period of time.

      11. Death; Disability.

            A. If an ISO optionee ceases to be employed by the Company and all
Related Corporations by reason of his death, any of his ISOs may be exercised,
to the extent of the number of shares of Common Stock with respect to which such
optionee could have exercised it on the date of his death by his estate, legal
representative or legatee who has acquired the ISO by will or by the laws of
descent and distribution, at any time prior to the earlier of the specified
expiration date of the ISO or twelve (12) months from the date of the optionee's
death.

            B. If an ISO optionee ceases to be employed by the Company and all
Related Corporations of the Company by reason of his disability, such optionee
shall have the right to exercise the ISO held by such optionee on the date of
termination of employment, to the extent of the number of shares of Common Stock
with respect to which such optionee could have exercised such ISO on such date,
at any time prior to the earlier of the specified expiration date of such ISO or
twelve (12) months from the date of the termination of the optionee's
employment. For the purposes of the Plan, the term "disability" shall mean
"permanent and total disability" as defined in Section 22(e)(3) of the Code or
successor statute.

      12. Assignability. No Stock Right shall be assignable or transferable
by the grantee except by will or by the laws of descent and distribution, and
during the lifetime of the grantee each Stock Right shall be exercisable only by
him. Notwithstanding the foregoing, the Committee may provide in an option
agreement that the optionee may transfer, without consideration for the
transfer, his Non-Qualified Options to members of his immediate family, to
trusts for the benefit of such family members, to partnerships in which such
family members are the only partners, or to charities. Shares of Common Stock
issued upon the exercise of Stock Rights shall be subject to such rights of
first refusal, repurchase rights and other restrictions on transfer in favor of
the Company as the Committee may determine at the time such Stock Rights are
granted.

                                       6
<PAGE>

      13. Terms and Conditions of Stock Rights. Stock Rights shall be evidenced
by instruments (which need not be identical) in such forms as the Committee may
from time to time approve. With respect to Options, such instruments shall
conform to the terms and conditions set forth in paragraphs 7 and 12 hereof and
may contain such other provisions as the Committee deems advisable which are not
inconsistent with the Plan, including restrictions applicable to shares of
Common Stock issuable upon exercise of Options. In granting any Non-Qualified
Option, the Committee may specify that such Non-Qualified Option shall be
subject to the restrictions set forth herein with respect to ISOs, or to such
other termination and cancellation provisions as the Committee may determine.
The Committee may from time to time confer authority and responsibility on one
or more of its own members and/or one or more officers of the Company to execute
and deliver such instruments. The proper officers of the Company are authorized
and directed to take any and all action necessary or advisable from time to time
to carry out the terms of such instruments.

      14. Adjustments. Upon the occurrence of any of the following events, the
total number and type of securities authorized to be issued under this Plan and
each participant's rights with respect to Stock Rights granted to him hereunder
shall be adjusted as hereinafter provided, unless otherwise specifically
provided in the written agreement between such participant and the Company
relating to such Stock Rights:

            A. If the shares of Common Stock shall be subdivided or combined
into a greater or smaller number of shares or if the Company shall issue any
shares of Common Stock as a stock dividend on its outstanding Common Stock, the
number of shares of Common Stock authorized for issuance pursuant to this Plan
and deliverable upon the exercise of Options shall be appropriately increased or
decreased proportionately, and appropriate adjustments shall be made in the
purchase price per share to reflect such subdivision, combination or stock
dividend.

            B. If the Company is to be consolidated with or acquired by another
entity in a merger, sale of all or substantially all of the Company's assets or
otherwise (an "Acquisition"), the Plan and all Options granted hereunder shall
terminate unless the Committee or the board of directors of any entity assuming
the obligations of the Company hereunder (the "Successor Board"), in connection
with the Acquisition, make provision for the assumption of Options heretofore
granted, or the substitution of such Options with new options of the successor
entity or parent thereof with appropriate adjustment as to the number and kind
of shares and, if appropriate, the per share exercise prices. In the event of
such termination, each optionee shall be permitted to exercise for a period of
at least 15 days prior to the date of such termination (1) all Options held by
such optionee which are then exercisable, and (2) such number of additional
Options held by such optionee, to the extent such options are not then
exercisable, as may be specified in the relevant option agreement, if any.

            C. In the event of a recapitalization or reorganization of the
Company (other

                                       7
<PAGE>

than a transaction described in subparagraph B above) pursuant to which
securities of the Company or of another corporation are issued with respect to
the outstanding shares of Common Stock, the number and type of securities
authorized for issuance pursuant to the Plan shall be appropriately adjusted and
an optionee upon exercising an Option shall be entitled to receive for the
purchase price paid upon such exercise the securities he would have received if
he had exercised his Option prior to such recapitalization or reorganization.

            D. Notwithstanding the foregoing, any adjustments made pursuant to
subparagraphs A, B or C with respect to ISOs shall be made only after the
Committee, after consulting with counsel for the Company, determines whether
such adjustments would constitute a "modification" of such ISOs (as that term is
defined in Section 424 of the Code) or would cause any adverse tax consequences
for the holders of such ISOs. If the Committee determines that such adjustments
made with respect to ISOs would constitute a modification of such ISOs, it may
refrain from making such adjustments.

            E. In the event of the proposed dissolution or liquidation of the
Company, each Option will terminate immediately prior to the consummation of
such proposed action or at such other time and subject to such other conditions
as shall be determined by the Committee.

            F. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares subject to Options or the number
and type of securities authorized to be issued pursuant to the Plan. No
adjustments shall be made for dividends paid in cash or in property other than
securities of the Company.

            G. No fractional shares shall be issued under the Plan and the
optionee shall receive from the Company cash in lieu of such fractional shares.

            H. Upon the happening of any of the foregoing events described in
subparagraphs A, B or C above, the class and aggregate number of shares set
forth in paragraph hereof that are subject to Stock Rights which previously have
been or subsequently may be granted under the Plan shall also be appropriately
adjusted to reflect the events described in such subparagraphs. The Committee or
the Successor Board shall determine the specific adjustments to be made under
this paragraph 14 and, subject to paragraph 2, its determination shall be
conclusive.

            I. If any person or entity owning restricted Common Stock obtained
by exercise of a Stock Right made hereunder receives shares or securities in
connection with a corporate transaction described in subparagraphs A, B or C
above as a result of owning such restricted Common Stock, such shares or
securities or cash shall be subject to all of the conditions and restrictions
applicable to the restricted Common Stock with respect to which such

                                       8
<PAGE>

shares or securities were issued, unless otherwise determined by the Committee
or the Successor Board.

            J. The Committee may grant Stock Rights under the Plan in
substitution for stock and stock based awards held by employees of another
corporation who concurrently become directors, officers, employees or
consultants of the Company or a Related Corporation as the result of a merger or
consolidation of the employing corporation with the Company or a Related
Corporation or the acquisition by the Company or a Related Corporation of
property or stock of the employing corporation. The Committee may direct that
the substitute awards be granted on such terms and conditions as the Committee
considers appropriate in the circumstances. Any substitute Stock Rights granted
under the Plan in accordance with this Section shall not count against the share
limitation set forth in Section 5.

      15. Means of Exercising Stock Rights. A Stock Right (or any part or
installment thereof) shall be exercised by giving written notice to the Company
at its principal office address. Such notice shall identify the Stock Right
being exercised and specify the number of shares as to which such Stock Right is
being exercised, accompanied by full payment of the purchase price therefor
either (a) in United States dollars in cash or by check, or (b) if authorized by
the applicable Option agreement or at the discretion of the Committee, through
delivery of shares of Common Stock that the optionee has beneficially owned for
more than six months and which the optionee may freely transfer having a fair
market value equal as of the date of the exercise to the cash exercise price of
the Stock Right, or (c) at the discretion of the Committee, by delivery of the
grantee's personal note (which shall be recourse or partially non-recourse at
the discretion of the Committee) bearing interest payable not less than annually
at no less than 100% of the lowest applicable federal rate, as defined in
Section 1274(d) of the Code; provided that at least so much of the exercise
price as represents the par value of the Common Stock shall be paid other than
with a note, or (d) at the discretion of the Committee, by the optionee
delivering to the Company a properly executed exercise notice together with
irrevocable instructions to a broker to promptly deliver to the Company cash or
a check payable and acceptable to the Company to pay the purchase price;
provided that in the event the optionee chooses to pay the purchase price as so
provided, the optionee and the broker shall comply with such procedures and
enter into such agreements of indemnity and other agreements as the Committee
shall prescribe as a condition of such payment procedure, or (e) at the
discretion of the Committee, by any combination of (a), (b), (c) and (d) above.
The holder of a Stock Right shall not have the rights of a stockholder with
respect to the shares covered by his Stock Right until the date of issuance of a
stock certificate to him for such shares. Except as expressly provided above in
paragraph 14 with respect to changes in capitalization and stock dividends, no
adjustment shall be made for dividends or similar rights for which the record
date is before the date such stock certificate is issued.

      16. Term and Amendment of Plan.

            A. This Plan shall become effective upon approval by the holders of
a

                                       9
<PAGE>

majority of the shares of Common Stock of the Company present or represented and
entitled to vote at a meeting of stockholders. Subject to such approval by the
stockholders and to the requirement that no Common Stock may be issued hereunder
prior to such approval, Stock Options may be granted hereunder on and after
adoption of this Plan by the Board. This Plan was adopted by the Board on May
10, 1996, amended by the Board on May 17, 1996 and approved, in such amended
form, by the stockholders of the Company on May 20, 1996, amended by the Board
on October 9, 1996, amended by the Board on March 11, 1999 and approved, in such
amended form, by the stockholders of the Company on June 25, 1999, amended by
the Board on October 6, 2000, and amended by the Board on January 26, 2001 and
approved, in such amended form, by the stockholders of the Company on March 22,
2001. The Plan shall continue in effect until the earlier of: (i) May 9, 2006,
(ii) its termination by the Board, or (iii) the date on which all of the shares
of Common Stock available for issuance under the Plan have been issued and all
restrictions on such shares under the terms of the Plan and the Stock Right
agreements have lapsed.

            B. The Board may terminate or amend the Plan in any respect at any
time, except that, without the approval of the stockholders obtained within 12
months before or after the Board adopts a resolution authorizing any of the
following actions: (a) the total number of shares that may be issued under the
Plan may not be increased (except by adjustment pursuant to paragraph 14); (b)
the provisions of paragraph 4 regarding eligibility for grants of ISOs may not
be modified; (c) the provisions of paragraph 7(B) regarding the exercise price
at which shares may be offered pursuant to ISOs may not be modified (except by
adjustment pursuant to paragraph 14); and (d) the expiration date of the Plan
may not be extended. Plan amendments shall be subject to the approval by the
stockholders of the Company, if and to the extent determined by the Committee to
be necessary to ensure that ISOs granted under the Plan are qualified under
Section 422 of the Code. In no event may action of the Board or stockholders
adversely affect the right of a grantee, without his consent, under any Stock
Right previously granted to him unless required to ensure that the Option is
treated as an ISO or to comply with applicable law.

      17. Conversion of ISOs into Non-Qualified Options; Termination of ISOs.
The Committee, at the written request of any optionee, may in its discretion
take such actions as may be necessary to convert such optionee's ISO (or any
installments or portions of installments thereof) that have been exercised on
the date of conversion into Non-Qualified Options at any time prior to the
expiration of such ISOs, regardless of whether the optionee is an employee of
the Company or a Related Corporation at the time of such conversion. Such
actions may include, but not be limited to, extending the exercise period or
reducing the exercise price of the appropriate installments of such Options. At
the time of such conversion, the Committee (with the consent of the optionee)
may impose such conditions on the exercise of the resulting Non-Qualified
Options as the Committee in its discretion may determine, provided that such
conditions shall not be inconsistent with this Plan. Nothing in the Plan shall
be deemed to give any optionee the right to have such optionee's ISOs converted
into Non-Qualified Options, and

                                       10
<PAGE>

no such conversion shall occur until and unless the Committee takes appropriate
action. The Committee, with the consent of the optionee, may also terminate any
portion of any ISO that has not been exercised at the time of such termination.

      18. Application of Funds. The proceeds received by the Company from the
sale of shares pursuant to Options granted and Purchases authorized under the
Plan shall be used for general corporate purposes.

      19. Governmental Regulation. The Company's obligation to sell and deliver
shares of the Common Stock under this Plan is subject to the approval of any
governmental authority required in connection with the authorization, issuance
or sale of such shares.

      20. Withholding of Additional Income Taxes. Upon the exercise of a
Non-Qualified Option, the making of a Purchase of Common Stock for less than its
fair market value, or the vesting of restricted Common Stock acquired on the
exercise of a Stock Right hereunder, the Company, in accordance with Section
3402(a) of the Code, may require the optionee or purchaser to pay any taxes
required to be withheld in respect of the amount that is considered compensation
includable in such person's gross income. The Company and its Related
Corporations shall, to the extent permitted by law, have the right to deduct any
such taxes from any payment otherwise due to the optionee or purchaser. The
Committee in its discretion may condition (i) the exercise of an Option, (ii)
the making of a Purchase of Common Stock for less than its fair market value, or
(iii) the vesting of restricted Common Stock acquired by exercising a Stock
Right on the grantee's payment of such additional withholding taxes.

            A. With the approval of the Committee, a participant may elect to
have the minimum required tax withholding obligation satisfied, in whole or in
part, by (i) authorizing the Company to withhold from shares of Common Stock to
be issued pursuant to any Stock Right number of shares with an aggregate fair
market value that would satisfy the withholding amount due, or (ii) transferring
to the Company shares of Common Stock owned by the participant with an aggregate
fair market value that would satisfy the withholding amount due. The fair market
value of any shares of Common Stock withheld or tendered to satisfy any such tax
withholding obligation shall not exceed the amount determined by the applicable
statutory withholding rates.

      21. Notice to Company of Disqualifying Disposition. Each employee who
receives an ISO must agree to notify the Company in writing immediately after
the employee makes a Disqualifying Disposition (as hereinafter defined) of any
Common Stock acquired pursuant to the exercise of an ISO. A "Disqualifying
Disposition" is any disposition (including any sale) of such Common Stock before
the later of (a) two years after the date the employee was granted the ISO, or
(b) one year after the date the employee acquired Common Stock by exercising the
ISO. If the employee has died before such stock is sold, these holding period
requirements do not apply and no Disqualifying Disposition can occur thereafter.

                                       11

      22. Governing Law; Construction. The validity and construction of the Plan
and the instruments evidencing Stock Rights shall be governed by the laws of the
State of Delaware. In construing this Plan, the singular shall include the
plural and the masculine gender shall include the feminine and neuter, unless
the context otherwise requires. In the event of a conflict between the terms and
provisions of this Plan and the terms and provisions of any Stock Right
agreement, the terms and provisions of this Plan shall govern.
